The association between clinician-based common terminology criteria for adverse events (CTCAE) and patient-reported outcomes (PRO): a systematic review

Comparing symptom reporting by prostate cancer patients and healthcare professionals in the international multicentre REQUITE study

INTRODUCTION

Previous studies showed that healthcare professionals and patients had only moderate to low agreement on their assessment of treatment-related symptoms. We aimed to determine the levels of agreement in a large cohort of prostate cancer patients.

METHODS

Analyses were made of data from 1,756 prostate cancer patients treated with external beam radiotherapy (RT) and/or brachytherapy in Europe and the USA and recruited into the prospective multicentre observational REQUITE study. Eleven pelvic symptoms at the end of RT were compared after translating patient-reported outcomes (PROs) into CTCAE-based healthcare professional ratings. Gwet's AC2 agreement coefficient and 95% confidence intervals were calculated for each symptom. To compare severity of grading between patients and healthcare professionals, percent agreement and deviations for each symptom were graphically depicted. Stratified and sensitivity analyses were conducted to identify potential influencing factors and to assess heterogeneity and robustness of results.

RESULTS

The agreement for the 11 pelvic symptoms varied from very good (AC2 > 0.8: haematuria, rectal bleeding, management of sphincter control) to poor agreement (AC2 ≤ 0.2: proctitis and urinary urgency). Fatigue had a negative impact on the agreement. Patients tended to grade symptoms more severely than healthcare professionals. Information on sexual dysfunction was missing more frequently in healthcare professional assessment than PROs.

CONCLUSION

Agreement was better for observable than subjective symptoms, with patients usually grading symptoms more severely than healthcare professionals. Our findings emphasize that PROs should complement symptom assessment by healthcare professionals and be taken into consideration for clinical decision-making to incorporate the patient perspective.

Sexual Health Update in Women

The Clinical Update series is intended to help busy clinicians stay up to date with recently published important and potentially practice-changing articles on topics pertinent to the care of women. In this update on sexual health, we review studies on use of vaginal dilators for vaginal stenosis in gynecologic cancer survivors, sexual dysfunction in transgender people, as well as studies evaluating the effect of physical activity and infertility on female sexual health.

A Retrospective Analysis of Conversion Therapy with Lenvatinib, Sintilimab, and Arterially-Directed Therapy in Patients with Initially Unresectable Hepatocellular Carcinoma

Purpose

The purpose of this study was to investigate the triple-combination therapy of lenvatinib plus sintilimab plus arterially-directed therapy as a conversion therapy for initially unresectable hepatocellular carcinoma (HCC).

Patients and Methods

We retrospectively analyzed data from all HCC patients who underwent lenvatinib plus sintilimab plus arterially-directed therapy at Tianjin Medical University Cancer Hospital between December 2018 and October 2020. Of 98 enrolled patients, 37 patients were classified as potentially resectable. We compared the potentially resectable population (PRP) with the non-potentially resectable population (NPRP). The primary study endpoint was conversion rate, and secondary endpoints included progression-free survival (PFS), overall survival (OS), objective response rate (ORR), disease control rate (DCR), and safety.

Results

The baseline characteristics were comparable between populations except for a higher proportion of patients with extrahepatic metastases in the NPRP versus PRP (23/61 [37.7%] vs 3/37 [8.1%], respectively; p=0.003). For PRP, the ORR was 67.6% based on RECIST v1.1 (75.7% based on mRECIST), conversion rate was 40.5% (15/37). Of the 15 patients who underwent surgical resection, three achieved complete pathological remission. The median follow-up for all patients was 28 months (range: 2-47). For NPRP, the ORR was 22.9% based on RECIST v1.1 (31.1% based on mRECIST), The median PFS for PRP was significantly longer than that of NPRP (25 vs 13 months, p = 0.0025). The median OS for PRP was significantly longer than that of NPRP (not reached VS 21 months, p=0.014). Hypertension was the most common grade ≥3 adverse reaction in both PRP and NPRP. No new safety signals were observed for any of the treatments.

Conclusion

The triple-combination therapy of lenvatinib plus sintilimab plus arterially-directed therapy can convert potentially unresectable HCC into resectable disease and improve long-term survival.

Patient-reported experiences with side effects of kidney cancer therapies and corresponding information flow

BACKGROUND

Treatment options for metastatic renal cell carcinoma (mRCC) have improved over recent years. Various therapies for metastatic renal cell carcinoma are currently approved for first and successive lines. Having various treatment options makes it important to reflect how patients experience side effects in the real-world setting. So far, data on the side effects of these treatments have only been collected within clinical trials, and have been mostly assessed by the investigator and not as patient-reported outcomes. Our aim was to determine patient-reported experiences of side effects in the real-world setting and to evaluate the doctor-patient communication regarding side effects. Data were collected via an anonymous, voluntary online survey given to members of a support group for RCC; the questionnaire was completed by 104 mRCC patients.

RESULTS

89.1% of participants were suffering from side effects of any grade. These appeared to be higher for patients treated with tyrosine kinase inhibitors compared to those treated with immune-checkpoint inhibitors (98.4% vs. 68.4%). However, information on side effects is scarce: 4.0% had never heard anything about them while only 18.8% of participants received detailed information on possible side effects. Although 85.6% of participants reported side effects to their physician, 34.6% did not encounter an improvement. Limitations of the study include the design as an online questionnaire and the small sample, consisting only of members of a support group.

CONCLUSIONS

Differences can be seen between patient-reported side effects within our survey and those based on clinical trials. A shift towards more patient-reported outcomes is needed. In addition, patients seeking the advice of their physician on side effects are in need of more-or better-information and support.

How do patients interpret and respond to a single-item global indicator of cancer treatment tolerability?

BACKGROUND

There is increasing interest in patient-reported measures of cancer treatment tolerability. A global measure of bother, the FACT GP5 item ("I am bothered by side effects of treatment") is potentially useful for regulatory, research, and clinical use. To understand this item's appropriateness for capturing treatment tolerability, we conducted cognitive interviews on this item with 3 samples of cancer patients.

METHODS

Patients with ovarian cancer (Study 1: N = 21; on treatment), lymphoma (Study 2: N = 14; on treatment), and colorectal or lung cancer (Study 3: N = 16; treatment naïve) were interviewed about GP5's understandability and relevance to their treatment side effects. What patients think about when answering GP5 was also assessed. In all studies, the interview included both structured and open-ended questions. Qualitative data were coded to extract themes and responses to structured questions were tallied.

RESULTS

Most patients on treatment (Studies 1 and 2) reported that the GP5 item wording is appropriate (88%) and its meaning is clear (97%). They were very confident or confident in their response (97%) and stated that GP5 was relevant to their cancer experience (97%). When answering GP5, patients considered their treatment and specific side effects. A large proportion (40%) of the treatment-naïve (Study 3) patients reported that GP5 was not relevant to their cancer treatment, and the largest proportion responded to GP5 thinking of negative side effect expectancies.

CONCLUSION

This study provides assurance that GP5 is a useful indicator of treatment tolerability, and is meaningful to people with cancer, especially once they have started treatment.

Cardiovascular adverse events associated with cyclophosphamide, pegylated liposomal doxorubicin, vincristine, and prednisone with or without rituximab ((R)-CDOP) in non-Hodgkin’s lymphoma: A systematic review and meta-analysis

Background: The (R)-CDOP combination regimen, based on pegylated liposomal doxorubicin, is increasingly used for elderly patients with non-Hodgkin’s lymphoma. However, the cardiotoxicity and efficacy of the (R)-CDOP regimen compared with conventional anthracyclines have not been demonstrated in the general population. Therefore, this systematic review and meta-analysis evaluated the risk of cardiotoxicity and efficacy associated with the (R)-CDOP regimen in patients with non-Hodgkin’s lymphoma.

Methods: PubMed, Embase, Cochrane Library, CNKI, WanFang Database, and VIP were searched. The search covered the period from the start of the clinical use of (R)-CDOP to April 2022. We searched the literature for cardiovascular adverse events associated with (R)-CDOP in non-Hodgkin’s lymphoma. The data were analyzed using R 4.2.0 and Stata 12.0.

Results: From the included studies, the important findings were as follows: total cardiovascular event rate, 7.45% (95% confidence interval [CI] = 4.86%–10.44%); non-serious cardiovascular adverse event rate, 6.48% (95% CI = 3.70%–9.8%); serious cardiovascular adverse event rate, 0.67% (95% CI = 0.00%–2.12%); heart failure rate, 0.55% (95% CI = 0.00%–1.93%); rate of treatment discontinuation attributable to left ventricular dysfunction or heart failure, 0.02% (95% CI = 0.00%–0.57%); and cardiovascular death rate, 0.00% (95% CI = 0.00%–0.37%). Compared with the (R)-CHOP regimen, the (R)-CDOP regimen reduced the risk of cardiovascular events, including total cardiovascular adverse events (odds ratio [OR] = 0.161, 95% CI = 0.103–0.251, p < 0.001, and NNT = 3.7), non-serious cardiovascular adverse events (OR = 0.171, 95% CI = 0.093–0.314, p < 0.001, and NNT = 3.6), serious cardiovascular adverse events (OR = 0.252, 95% CI = 0.119–0.535, p < 0.001, and NNT = 6.8), and heart failure (OR = 0.294, 95% CI = 0.128–0.674, p = 0.004, and NNT = 9.5). To evaluate the survival benefits, we compared (R)-CDOP and (R)-CHOP regimens. We found that the (R)-CDOP regimen was no less efficacious, including complete remission (CR) (OR = 1.398, 95% CI = 0.997–1.960, and p = 0.052), partial response (PR) (OR = 1.631, 95% CI = 1.162–2.289, and p = 0.005), objective response rate (ORR) (OR = 2.236, 95% CI = 1.594–3.135, and p < 0.001), stable disease (SD) (OR = 0.526, 95% CI = 0.356–0.776, and p = 0.001), and progressive disease (PD) (OR = 0.537, 95% CI = 0.323–0.894, and p = 0.017).

Conclusion: Our findings suggested that the (R)-CDOP regimen had a lower risk of cardiovascular adverse events in non-Hodgkin’s lymphoma than the (R)-CHOP regimen, demonstrating its safety with regard to cardiotoxicity. In addition, this study found the (R)-CDOP regimen was no less efficacious than the (R)-CHOP regimen in the treatment of non-Hodgkin’s lymphoma. These findings need to be validated by higher-quality research because of the limited number and quality of included studies.

Patient-centered dosing: oncologists' perspectives about treatment-related side effects and individualized dosing for patients with metastatic breast cancer (MBC)

PURPOSE

Although metastatic breast cancer (MBC) is treatable, it is not curable and most patients remain on treatment indefinitely. While oncologists commonly prescribe the recommended starting dose (RSD) from the FDA-approved label, patient tolerance may differ from that seen in clinical trials. We report on a survey of medical oncologists' perspectives about treatment-related toxicity and willingness to discuss flexible dosing with patients.

METHODS

We disseminated a confidential survey via social media/email in Spring 2021. Eligible respondents needed to be US-based medical oncologists with experience treating patients with MBC.

RESULTS

Of 131 responses, 119 were eligible. Physicians estimated that 47% of their patients reported distressing treatment-related side effects; of these, 15% visited the Emergency Room/hospital and 37% missed treatment. 74% (n = 87) of doctors reported improvement of patient symptoms after dose reduction. 87% (n = 104) indicated that they had ever, if appropriate, initiated treatment at lower doses. Most (85%, n = 101) respondents did not believe that the RSD is always more effective than a lower dose and 97% (n = 115) were willing to discuss individualized dosing with patients.

CONCLUSION

Treatment-related side effects are prevalent among patients with MBC, resulting in missed treatments and acute care visits. To help patients tolerate treatment, oncologists may decrease initial and/or subsequent doses. The majority of oncologists reject the premise that a higher dose is always superior and are willing to discuss individualized dosing with patients. Given potential improvements regarding quality of life and clinical care, dose modifications should be part of routine shared decision-making between patients and oncologists.

An implementation study of electronic assessment of patient-reported outcomes in inpatient radiation oncology

Purpose

Despite evidence for clinical benefits, recommendations in guidelines, and options for electronic data collection, routine assessment of patient-reported outcomes (PROs) is mostly not implemented in clinical practice. This study aimed to plan, conduct and evaluate the implementation of electronic PRO (e-PRO) assessment in the clinical routine of an inpatient radiation oncology clinic.

Methods

The guideline- and evidence-based, stepwise approach of this single-center implementation study comprised preparatory analyses of current practice, selection of assessment instruments and times, development of staff training, and evidence-based recommendations regarding the use of the e-PRO assessment, as well as on-site support of the implementation. Process evaluation focused on potential clinical benefit (number of documented symptoms and supportive measures), feasibility and acceptance (patient contacts resulting in completion/non-completion of the e-PRO assessment, reasons for non-completion, preconditions, facilitators and barriers of implementation), and required resources (duration of patient contacts to explain/support the completion).

Results

Selection of instruments and assessment times resulted in initial assessment at admission (EORTC QLQ-C30, QSR 10), daily symptom monitoring (EORTC single items), and assessment at discharge (EORTC QLQ-C30). Recommendations for PRO-based clinical action and self-management advice for patients concerning nine core symptoms were developed. Staff training comprised group and face-to-face meetings and an additional e-learning course was developed. Analyses of clinical records showed that e-PRO assessment identified more symptoms followed by a higher number of supportive measures compared to records of patients without e-PRO assessment. Analysis of n = 1597 patient contacts resulted in n = 1355 (84.9%) completed e-PROs (initial assessment: n = 355, monitoring: n = 967, final assessment: n = 44) and n = 242 (15.2%) non-completions. Instructions or support to complete e-PROs took on average 5.5 ± 5.3 min per patient contact. The most challenging issue was the integration of the results in clinical practice.

Conclusion

E-PRO assessment in oncologic inpatient settings is acceptable for patients and can support symptom identification and the initiation of supportive measures. The challenge of making the “data actionable” within the clinical workflow and motivating clinical staff to use the results became evident.

Cancer patients’ perceptions regarding their symptoms and functioning are important as they can differ from a professional assessment. Patients’ perceptions and self-assessment can be collected via electronic devices. Thus, the clinical staff can see a graphic overview of individual disease-related burden. Despite studies indicating the benefit of this assessment for care and symptom management, it is not integrated into routine care so far. The aim of our study was, to plan, conduct and evaluate the implementation of electronic patient-reported assessment in a radio-oncology inpatient clinic under “real-life” clinical conditions instead of study conditions. Patients could complete an electronic assessment at the beginning/end and during their treatment. Results indicate that electronic self-assessment can identify more symptoms than the assessment of physicians and nurses. Patients completing a self-assessment are more likely to receive supportive measures. The majority of 80–90% of patients were willing to complete a self-assessment. On average 5–6 min were needed to explain or support the completion. While the intervention was feasible and acceptable for patients, motivating clinical staff using its results was most challenging. The importance of technical support became evident.

Application value of modified skin expansion in PICC catheterization under the guidance of B-ultrasound in gastrointestinal cancer patients with chemotherapy

OBJECTIVE

To investigate the clinical value of modified skin expansion in peripherally inserted central venous catheter (PICC) catheterization under the guidance of B-ultrasound in gastrointestinal cancer patients with chemotherapy.

METHODS

In this retrospective study, 60 gastrointestinal cancer patients with chemotherapy were included and divided into an experimental group (treated with modified skin expansion in PICC catheterization under the guidance of B-ultrasound) and a control group (treated with the longitudinal skin expansion in PICC catheterization under the guidance of B-ultrasound). The bleeding volume, pain score, success rate of one-time PICC catheterization and the incidence of complication were compared between the two groups.

RESULTS

The modified skin expansion in PICC catheterization under the guidance of B-ultrasound had obvious effect on gastrointestinal cancer patients with chemotherapy. The VAS scores were significantly lower after PICC catheterization in the experimental group compared with the control group (P < 0.05). The success rate of one-time PICC catheterization in the experimental group was significantly higher than that in the control group. Moreover, the incidence of complication and massive bleeding during puncture and 24 hours after puncture was significantly lower in the observation group compared with that in the control group.

CONCLUSIONS

Modified skin expansion in PICC catheterization under the guidance of B-ultrasound in gastrointestinal cancer patients with chemotherapy can improve the success rate of one-time sheath delivery, effectively reduce the amount of blood leakage after catheterization, reduce patients' pain and reduce the incidence of complications.

Linking the European Organisation for Research and Treatment of Cancer Item Library to the Common Terminology Criteria for Adverse Events

PURPOSE

The European Organisation for Research and Treatment of Cancer (EORTC) Item Library is an interactive online platform currently composed of 950 unique items (questions) derived from 67 patient-reported outcome (PRO) questionnaires. PROs complement clinician adverse event (AE) reporting classifications like the Common Terminology Criteria for Adverse Events (CTCAE). This work aims to create a standardized framework using the CTCAE to systematically classify symptomatic AEs from the EORTC Item Library through linking individual items to corresponding AEs.

METHODS

The EORTC Item Library items were searched for within the CTCAE (v5.0) and linked to an AE if they were described within the AE's title, description, or grading. Symptoms described in EORTC items but not located in the CTCAE were coded as missing symptoms. Other nonsymptom EORTC items, not described within the CTCAE were assigned a non-CTCAE descriptive classification. Further descriptive codes (eg, multiple issues) were allocated to enable descriptive analysis. Two raters independently coded 26.2% (n = 249) of the items. The remaining 701 items were coded by one rater and verified by the second, followed by discussion with two additional raters to reach consensus.

RESULTS

Overall, 625 (65.8%) EORTC items were linked to 208 different AEs. Three hundred sixty-nine items provide information about non-CTCAE cancer-related issues and were categorized into seven descriptive classifications, including body image; emotional impact of a symptom, diagnosis, or treatment; global health and quality of life; and impact on life and daily activities. Inter-rater agreement for independent coding was 79.1%. Bowel urgency and tenesmus were identified as missing symptoms in CTCAEv5.0.

CONCLUSION

The EORTC Item Library provides considerable coverage of CTCAE toxicities, along with other complementary issues important to patients with cancer. Using the CTCAE clinical framework to classify symptomatic PRO items may facilitate PRO selection and use in clinical trials and routine care.

Evaluation of the patient experience of symptomatic adverse events on Phase I clinical trials using PRO-CTCAE

BACKGROUND

Adverse event (AE) reporting in early-phase clinical trials is essential in determining the tolerability of experimental anticancer therapies. The patient-reported outcome version of the CTCAE (PRO-CTCAE) evaluates AE components such as severity and interference in daily life. The aim of this study was to correlate the grade of clinician-reported AEs with patients' reported experience of these toxicities using PRO-CTCAE.

METHODS

Patients with advanced solid tumours enrolled on Phase I clinical trials were surveyed using the PRO-CTCAE. Symptomatic AEs were recorded by physicians using the CTCAE. A logistic regression model was used to assess associations between CTCAE grade and PRO responses.

RESULTS

Of 219 evaluable patients, 81 experienced a high-grade (3/4) clinician-reported symptom, and of these, only 32 (40%) and 26 (32%) patients concordantly reported these as either severe or very severe, and interfering with daily life either 'quite a bit' or 'very much', respectively. Of the 137 patients who experienced a low-grade (1/2) clinician-reported AE as their worst symptom, 98 (72%) and 118 (86%) patients concordantly reported these as either mild-moderate severity and minimally interfering with daily life, respectively. There was a statistically significant association between clinician-reported AE grade and interference. Interference scores were also associated with dose reductions.

CONCLUSION

This is the first study to explore patient-reported severity and interference from symptomatic toxicities and compare clinician grading of the same toxicities. The study provided further evidence to support the added value of the PRO-CTCAE in Phase I oncology trials, which would make AE reporting patient-centred. Further work is needed to determine how this would affect the assessment of tolerability.

Essential barriers and considerations for the implementation of electronic patient-reported outcome (ePRO) measures in oncological practice: contextualizing the results of a feasibility study with existing literature

Aim

Monitoring electronic patient-reported outcomes (ePRO) can provide various benefits to cancer patients, such as enhanced quality of life, reduction of hospital admissions, and even prolonged survival. Furthermore, ePRO might offer significant benefits to patients under antineoplastic treatment in the context of the current COVID-19 pandemic. However, evidence on feasibility of ePRO in routine cancer care and barriers met in a real-life setting remains limited.

Subject and methods

We conducted a feasibility study among patients diagnosed with multiple myeloma currently under antineoplastic treatment. Patients filled out weekly ePRO questionnaires and were followed up for 6 months. In case of adverse events, an alert was sent to the clinic. We assessed uptake and adherence, as well as subjective perceptions of patients and clinic staff. A semi-structured literature review was conducted to contextualize results.

Results

Eleven patients were recruited and followed up for 6 months. Overall adherence was found at a high level and remained stable throughout the study period. Feedback from patients was positive; however, clinic staff expressed disappointment and frustration, criticising an increase of workload while not perceiving any benefit to the oncological treatment. Both findings were backed by evidence we found in literature.

Conclusions

Implementation of ePRO monitoring to routine cancer treatment seems to be feasible regarding patients' acceptance and compliance. However, integration of the tool into clinical workflow without increasing workload and deterring clinicians proves to be a major challenge.

Impact of Guidelines Regarding Dihydropyrimidine Dehydrogenase (DPD) Deficiency Screening Using Uracil-Based Phenotyping on the Reduction of Severe Side Effect of 5-Fluorouracil-Based Chemotherapy: A Propension Score Analysis

Dihydropyrimidine dehydrogenase (DPD) deficiency is associated with severe fluoropyrimidines-induced toxicity. As of September 2018, French recommendations call for screening for DPD deficiency by plasma uracil quantification prior to all fluoropyrimidine-based chemotherapy. A dose reduction of fluoropyrimidine is recommended when uracil concentration is equal to or greater than 16 ng/mL. This matched retrospective study assessed the impact of DPD screening on the reduction of severe side effects and on the management of DPD-deficient patients. Using a propensity score, we balanced the factors influencing 5-Fluorouracil (5-FU) toxicity. Then, the severity scores (G3 and G4 severity as well as their frequency) of patients who did not benefit from DPD screening were compared with those of patients who benefited from DPD screening for each treatment cycle (from 1 to 4). Among 349 screened patients, 198 treated patients were included. Among them, 31 (15.7%) had DPD deficiency (median uracilemia 19.8 ng/mL (range: 16.1−172.3)). The median toxicity severity score was higher in the unscreened group for each treatment cycle (0 vs. 1, p < 0.001 at each cycle from 1 to 4) as well as the cumulative score during all courses of treatment (p = 0.028). DPD-deficient patients received a significantly lower dose of 5-FU (p < 0.001). This study suggests that pretherapeutic plasmatic uracil assessment, along with 5-FU dosage adjustment, may be beneficial in reducing 5-FU toxicity in real-life patients.

Association between tumor response to systemic therapy and patient-reported disease symptoms

BACKGROUND

The association of treatment-induced tumor shrinkage with symptom palliation for patients with lung cancer remains unknown. We investigated this correlation using the Edmonton Symptom Assessment System-Revised.

METHODS

Using the in-hospital cancer registry, we identified patients receiving chemotherapy and/or immunotherapy for newly diagnosed advanced or metastatic lung cancer. Tumor response and post-treatment Edmonton Symptom Assessment System-Revised were obtained after 2-3 treatment cycles. Patients were divided into groups with or without >30% unidirectional tumor shrinkage (objective response [OR] or non-OR [N-OR] groups, respectively). They were further classified as good-objective response (>50% unidirectional tumor shrinkage), moderate-objective response (30-50% shrinkage), progressive disease (>20% tumor growth or new lesion) or stable disease (SD; N-objective response and non-progressive disease). The primary endpoint was change in the total Edmonton Symptom Assessment System-Revised score from baseline. The Mann-Whitney U test was used for analysis.

RESULTS

In total, 113 patients were enrolled. The total Edmonton Symptom Assessment System-Revised score was significantly more improved in the OR group versus the N-OR group (median: 5 vs. 2, respectively; P = 0.013). This association was more prominent in patients with small-cell lung cancer and large-cell neuroendocrine tumor than those with other histology. Sensitivity analyses showed that the total Edmonton Symptom Assessment System-Revised score was more improved in the OR group versus the SD group (median: 5 vs. 3, respectively; P = 0.029) and in the 'good-OR' group versus the 'moderate-OR and SD' group (median: 7.5 vs. 2, respectively; P = 0.003), suggesting that greater tumor shrinkage led to more symptom amelioration.

CONCLUSIONS

Tumor shrinkage was associated with Edmonton Symptom Assessment System-Revised score improvement in patients with lung cancer receiving systemic therapy.

Role of Consolidative Stereotactic Body Radiation Therapy in Oligoresistant/Oligoprogressive Pulmonary Parenchymal Metastases

Aim

To extend the survival of patients by providing local control of metastases in oligoresistance/oligoprogressive disease.

Methods

We retrospectively evaluated the efficacy of stereotactic body radiotherapy (SBRT) applied to 30 lesions in the lungs of 19 patients who were considered inoperable by the tumor board upon the development of oligoresistance/oligoprogressive lung metastasis while undergoing chemotherapy between January 2016 and December 2017. Each patient had one to five metastases in their lungs. The median SBRT biologic effective dose at α/β of 10 (BED₁₀) was 180.0 (IQR: 115.5–180.0) Gy.

Results

We obtained effective, low-toxicity results. The rates of local control were 89.4%, 84.2%, and 78.9% for the 1st, 2nd, and 3rd years, respectively. The median local control time was 4 (IQR: 3–6) months. The median overall survival (OS) was 36.3 (IQR: 29.7–42.9) months. The rates of OS for the 1st, 2nd, and 3rd years were 89.5%, 73.7%, and 61.4%, respectively. Despite the nonoccurrence of grade 4–5 toxicity in the lungs, six (31.6%) patients had grade 1–3 pulmonary pneumonia, one patient had a grade 4 skin ulceration, and two patients had increased chronic obstructive pulmonary disease in the follow-up period.

Discussion

In patients with oligometastatic lung tumors, SBRT is very effective in terms of progression-free survival and OS.

Evaluation of the implementation of Value-Based Healthcare with a weekly digital follow-up of lung cancer patients in clinical practice

OBJECTIVE

The aim of this study was to evaluate the implementation of Value-Based Healthcare principles for lung cancer patients in a large Belgian hospital. This hospital implemented a digital platform for the collection of patient-reported outcomes and the standardisation of care pathways. Also, a follow-up by the multidisciplinary care team was put in place.

METHODS

Evaluation was done by employing a mixed method approach with data analysis of all included patients (n = 201), a pilot study (n = 30) and semi-structured interviews with the care team (n = 5).

RESULTS

Overall, 95% of all lung cancer patients of two thoracic oncologists agreed to participate in the digital follow-up during the period January 2018 to September 2020 (201 participating patients). The response rates of those patients were high: 92% of the weekly questionnaires and 90% of the 6-weekly ICHOM questionnaires were responded. Based on the pilot study, we conclude that questions are clear and the platform is user-friendly for 90% of patients in the pilot. The interviews revealed that the weekly follow-up has a positive impact on the patient-provider communication and makes it easier to discuss psychological and palliative care needs.

CONCLUSION

This study shows a successful implementation of Value Based Healthcare with weekly digital follow-up. Clinical trial registration is as follows: www.

Acute toxicity and patient-reported outcomes in anal canal cancer: results of a pilot study

INTRODUCTION

Anal canal cancer (ACC) is uncommon. The gold standard of care is chemoradiotherapy treatment. However, this treatment is associated with considerable acute and late side effects. The aim of this pilot study was to evaluate acute toxicity and patient-reported outcomes (PRO) in these patients from planning to 3 months after treatment.

METHODS

Sixteen patients were recruited to this prospective observational study from March 2015 to December 2017. All patients received volumetric modulated arc therapy (VMAT) in 30#. Toxicity data were graded by a Radiation Oncologist using the Common Terminology Criteria for Adverse Effects (CTCAE) version 4 at planning, weekly during treatment, 6-week and 3-month post-treatment. PRO data were collected using the EORTC QLQ C30 and CR29 questionnaires completed by patients at planning, mid and end treatment and 3-month post-treatment.

RESULTS

The majority of toxicity and PRO items peaked in severity at the end of treatment (week 6). Skin was the only item where >50% of patients had ≥ grade 2 toxicity at any point with 75% having ≥ grade 2 at week 6. Patient-reported embarrassment significantly increased over time (P < 0.001). No meaningful relationships were found between PRO and CTCAE results.

CONCLUSION

After reaching their maximum severity at the end of treatment, the majority of toxicity and PRO items approached baseline levels by 3-month post-treatment. The results of this study suggest that PROs are an important complementary tool to CTCAE and provide greater understanding of patients' perception of treatment side effects.

Chronic Effects of Effective Oral Cannabidiol Delivery on 24-h Ambulatory Blood Pressure and Vascular Outcomes in Treated and Untreated Hypertension (HYPER-H21-4): Study Protocol for a Randomized, Placebo-Controlled, and Crossover Study

Accumulating data from both human and animal studies suggest that cannabidiol (CBD) may be associated with improved cardiovascular function, markedly with regard to reduction in blood pressure and improved endothelial function. However, there is a lack of randomized studies to support these notions, especially in at-risk populations. The principal aim of this randomized, placebo-controlled, and crossover study is to examine the influence of chronic CBD administration on 24-h blood pressure in individuals with mild or moderate hypertension who are either untreated or receiving standard care therapy. The secondary aims of the study are to determine the safety and tolerability of 5 weeks of CBD administration, and to quantify the effect on arterial stiffness, CBD and vascular health biomarkers, inflammation, heart rate variability, and psychological well-being in both groups of patients. The present single-center study is designed as a triple blind (Participant, Investigator, Outcomes Assessor), placebo-controlled, crossover pilot study in which 70 hypertensive volunteers (aged 40–70 years) will receive DehydraTECH2.0 CBD formulation and placebo in a crossover manner. We believe that comprehensive analyses that will be performed in the present trial will decipher whether CBD is in fact a safe and valuable supplement for patients with treated and untreated hypertension.

Longitudinal Collection of Patient-Reported Outcomes and Activity Data during CAR-T Therapy: Feasibility, Acceptability, and Data Visualization

Background: Clinicians must closely monitor patients for toxicities after chimeric antigen receptor T-cell therapy (CAR-T). Patient-reported outcomes (PROs) (e.g., toxicities, quality of life) and activity data (e.g., steps, sleep) may complement clinicians’ observations. This study tested the feasibility and acceptability of collecting PROs and activity data from patients with hematologic malignancies during CAR-T and explored preliminary data patterns. Methods: Participants wore a Fitbit tracker and completed PROs at several timepoints through 90-days post-infusion. Feasibility was assessed with a priori benchmarks for recruitment (≥50%), retention (≥70%), PRO completion (≥70%), and days wearing the Fitbit (≥50%). Acceptability was assessed with participant satisfaction (a priori benchmark > 2 on a 0−4 scale). Results: Participants (N = 12) were M = 66 years old (SD = 7). Rates of recruitment (68%), retention (83%), PRO completion (85%), and days wearing the Fitbit (85%) indicated feasibility. Satisfaction with completing the PROs (M = 3.2, SD = 0.5) and wearing the Fitbit (M = 2.9, SD = 0.5) indicated acceptability. Preliminary data patterns suggested that participants with better treatment response (vs. progressive disease) had a higher toxicity burden. Conclusions: Longitudinal PRO and activity data collection was feasible and acceptable. Data collected on a larger scale may be used to specify risk prediction models to identify predictors of severe CAR-T-related toxicities and inform early interventions.

Lack of Concordance in Symptomatic Adverse Event Reporting by Children, Clinicians, and Caregivers: Implications for Cancer Clinical Trials

PURPOSE

To examine concordance in symptomatic adverse event (AE) grading using the Common Terminology Criteria for Adverse Events (CTCAE 4.0) for clinicians and its patient-reported outcome (PRO) versions for children (Ped-PRO-CTCAE) and caregivers (Ped-PRO-CTCAE [Caregiver]).

METHODS

Children age 7-18 years with a first cancer diagnosis, their clinicians, and caregivers completed CTCAE-based measures before starting a treatment course (T1) and after the treatment (T2). Grades (0-3) were assigned by each reporter for 15 core AEs spanning physical and mental health. Mean grades were compared between reporters using two-sample t-tests; agreement was estimated using weighted kappa (κ) statistics. Multivariable mixed regression models were used to evaluate associations of clinical factors with AE reporting concordance. Significance was set at α = .05 (two-sided).

RESULTS

There were 438 child-clinician-caregiver triads with complete data at either T1 or T2. For children, the mean age was 13 years (standard deviation = 3.4), 53.7% were male, 32.6% non-White, and 56.4% had leukemia/lymphoma. At T1, clinician mean AE grades were significantly lower (ie, better) than children for all AEs and remained significantly lower at T2 except for constipation, nausea, anorexia, neuropathy, and anxiety. Caregiver mean AE grades were similar to children at T1 and significantly higher (ie, worse) at T2 for nausea, vomiting, anorexia, pain, fatigue, anxiety, and depression. Agreement for child-clinician grading was poor-to-fair at T1 (κ range, 0.08-0.34) and T2 (0.11-0.35), and for child-caregiver, was fair-to-good at T1 (0.34-0.65) and T2 (0.24-0.60). No factors were consistently associated with reporter concordance across AEs.

CONCLUSION

Compared with children, symptomatic AEs were consistently under-reported by clinicians with low agreement and over-reported by caregivers with low-moderate agreement. Direct reporting by children using Ped-PRO-CTCAE or similar measures should be routinely incorporated for toxicity assessment in clinical trials.

Patient- and physician-reported pain after tyrosine kinase inhibitor discontinuation among patients with chronic myeloid leukemia

For patients with optimally treated chronic myeloid leukemia (CML), discontinuation of tyrosine kinase inhibitor (TKI) therapy can lead to treatment-free remission. In previous trials, TKI discontinuation has been associated with increased musculoskeletal pain in some patients ("withdrawal syndrome"), based on physician-reported adverse events (AE). Patient-reported pain has not been described. The Life After Stopping TKI study was a 14-site prospective, non-randomized clinical trial of TKI discontinuation. We defined increased pain after discontinuation as: (i) a physician-reported pain AE, (ii) a 2-level increase in self-reported musculoskeletal pain (4-level single item), or (iii) initiation of a medication for pain. We plotted the trajectory of patient-reported pain over time using a piecewise mixed-effects ordinal logistic model. Within 3 months of discontinuation, 35 of 172 patients (20.3%) had a physician-reported pain AE, 22 of 172 (12.8%) had an increase in self-reported pain, and 18 of 154 (11.7%) initiated a pain medication. Agreement among these measures was limited; overall, 60 of 172 patients (34.9%) had increased pain. Three patients (1.7%) restarted a TKI because of pain. The modelpredicted trajectory showed an increase in pain in the first 3 months followed by a decrease, returning to baseline levels by 6 months and further decreasing after that. This trajectory was similar among patients who did and did not restart TKI, suggesting that resuming a TKI for withdrawal syndrome may be necessary for some, but other approaches to manage pain should be tried so that patients can remain in treatment-free remission when possible.

Impact of electrochemotherapy in metastatic cutaneous melanoma: a contemporary systematic review and meta-analysis

BACKGROUND

Electrochemotherapy (ECT) harnesses electric pulses to enhance cytotoxic drug delivery into tumors and has entered the armamentarium to treat superficially metastatic melanoma. We performed a systematic review and meta-analysis to assess treatment patterns and patient outcomes.

METHODS

PubMed, Medline, Embase, and the Cochrane Library databases were queried for publication from inception to September 2020. Primary outcome measures were overall and complete response rate (ORR and CRR); secondary outcomes included local control rate (LCR) and overall survival (OS).

RESULTS

Twenty-seven studies met the selection criteria for a total of 1161 individuals (mean age 71 years) and 5308 tumors (weighted mean size 14 mm). The majority of patients (n = 1124) underwent bleomycin-ECT. Aggregate ORR was 77.6% (95% confidence interval [CI] 71.0 - 83.2%) and CRR 48% (95% CI 42 - 54%), with no significant difference between the route of bleomycin administration (ORR, 69.2 vs. 81.9% following intravenous or intratumoral bleomycin, p = .37) and tumor size (p = .69). When reported (n = 8 studies), 1- and 2-year LCR ranged from 54 to 89% and 72 to 74%, respectively, and 1-year OS (n = 3 studies) from 67 to 89%.

CONCLUSIONS

ECT with either intratumoral or intravenous bleomycin confers a high therapeutic response in cutaneous metastatic melanoma. Moderate evidence supports its low toxicity and durability of local control.HighlightsElectrochemotherapy (ECT) is associated with a 77% overall response rate (ORR).Intravenous and intratumoral bleomycin are equally effective.There are no relevant toxicity concerns.One-year local tumor control rate ranges from 54 to 89%.Current literature has significant variation in reporting.

Evaluating the implementation and impact of navigator-supported remote symptom monitoring and management: a protocol for a hybrid type 2 clinical trial

Background

Symptoms in patients with advanced cancer are often inadequately captured during encounters with the healthcare team. Emerging evidence demonstrates that weekly electronic home-based patient-reported symptom monitoring with automated alerts to clinicians reduces healthcare utilization, improves health-related quality of life, and lengthens survival. However, oncology practices have lagged in adopting remote symptom monitoring into routine practice, where specific patient populations may have unique barriers. One approach to overcoming barriers is utilizing resources from value-based payment models, such as patient navigators who are ideally positioned to assume a leadership role in remote symptom monitoring implementation. This implementation approach has not been tested in standard of care, and thus optimal implementation strategies are needed for large-scale roll-out.

Methods

This hybrid type 2 study design evaluates the implementation and effectiveness of remote symptom monitoring for all patients and for diverse populations in two Southern academic medical centers from 2021 to 2026. This study will utilize a pragmatic approach, evaluating real-world data collected during routine care for quantitative implementation and patient outcomes. The Consolidated Framework for Implementation Research (CFIR) will be used to conduct a qualitative evaluation at key time points to assess barriers and facilitators, implementation strategies, fidelity to implementation strategies, and perceived utility of these strategies. We will use a mixed-methods approach for data interpretation to finalize a formal implementation blueprint.

Discussion

This pragmatic evaluation of real-world implementation of remote symptom monitoring will generate a blueprint for future efforts to scale interventions across health systems with diverse patient populations within value-based healthcare models.

Health-Related Quality of Life and Side Effects in Gastrointestinal Stromal Tumor (GIST) Patients Treated with Tyrosine Kinase Inhibitors: A Systematic Review of the Literature

BACKGROUND

The introduction of tyrosine kinase inhibitors (TKIs) has revolutionized the treatment of gastrointestinal stromal tumors (GISTs), resulting in a substantial gain in median overall survival. Subsequently, health-related quality of life (HRQoL) has become more relevant. Here, we systematically review the available literature on HRQoL issues and side effects of different TKIs registered for the treatment of GIST.

METHODS

A search through five databases was performed. Full reports in English describing HRQoL outcomes and/or side effects in GIST patients on TKI therapy were included.

RESULTS

A total of 104 papers were included; 13 studies addressed HRQoL, and 96 studies investigated adverse events. HRQoL in patients treated with imatinib, regorafenib, and ripretinib remained stable, whereas most sunitinib-treated patients reported a decrease in HRQoL. Severe fatigue and fear of recurrence or progression were specifically assessed as HRQoL issues and had a negative impact on overall HRQoL as well as psychological and physical well-being. The majority of studies focused on physician-reported side effects. Nearly all GIST patients treated with a TKI experienced at least one adverse event, mostly mild to moderate.

CONCLUSIONS

Despite the fact that almost all patients treated with a TKI experienced side effects, this did not seem to affect overall HRQoL during TKI therapy. In daily practice, it are the side effects that hamper a patient's HRQoL resulting in treatment adjustments, suggesting that the reported side effects were underestimated by physicians, or the measures used to assess HRQoL do not capture all relevant issues that determine a GIST patient's HRQoL.

Continuous low-dose gemcitabine in primary cutaneous T cell lymphoma: a retrospective study

PURPOSE

the aim of our retrospective study was to evaluate the efficacy of a continuous therapy with a lower dosage of gemcitabine compared to those usually administered in patients with CTCL.

MATERIAL AND METHODS

twenty-two patients received different dosages of gemcitabine. Dosage and schedule of the drug were chosen on the basis of clinical features. Gemcitabine was given at 1000 mg every 15 days in 13 patients (4 MF, 9 SS); at 1000 mg at days +1, +8, +15 in 6 cases (3 MF, 3 SS).

RESULTS

All patients had been previously treated: four patients had received both skin directed and systemic treatments. Eighteen patients had received photopheresis, IFN, chemotherapy and immunotherapy. The Objective Response Rate (CR+PR) among all patients was 54.5% (12 of 22 patients) with a CR of 4.5% (1 of 22 patients) and a PR of 50% (11 of 22 patients). Patients with SS had an ORR of 61.5% (8 of 13 patients) with 1 CR (7%) and 7 PR (53.8%); patients with MF showed an ORR of 55.6% (5 of 9 patients) but no patients experienced CR (0%). The schedule with the highest efficacy and the lowest toxicity profile was 1000 mg every 15 days. Median PFS and OS in all patients were 17 and 45 months respectively. Gemcitabine was generally well tolerated. This article is protected by copyright. All rights reserved.

CONCLUSIONS

we have demonstrated that a much lower dose of gemcitabine (1000 mg once every 15 days) in patients with advanced-stage and refractory CTCL can lead to a durable response, with tolerable and manageable adverse effects. This article is protected by copyright. All rights reserved.

The Underestimated and Overlooked Burden of Diarrhea and Constipation in Cancer Patients

PURPOSE OF REVIEW

This review aims to summarize and discuss the diverse causes of two major gastrointestinal dysfunction symptoms, diarrhea and constipation, in cancer patients. We also discuss short- and long-term clinical, economic, and humanistic consequences, including the impact on cancer treatment regimens and patient quality of life, highlighting the limitations of the literature.

RECENT FINDINGS

Diarrhea and constipation as a result of cancer and its treatment can risk the success of anti-cancer therapies by requiring treatment delay or withdrawal, and imposes a substantial humanistic burden in patients with cancer. Despite its importance and frequency, gastrointestinal side effects may be overlooked due to the focus on cancer treatment, and the impact on patients may be underestimated. Additionally, the burden reported may not fully reflect current cancer management, particularly the true impact of economic consequences. A full understanding of the burden of diarrhea and constipation in patients with cancer is required, including broad evaluation of clinical considerations, the patient experience, and an updated assessment of economic burden. This would improve caregivers' appreciation of the impact of gastrointestinal dysfunction and aid the prioritization of future research efforts.

Recurrent brain metastases: the role of resection of in a comprehensive multidisciplinary treatment setting

Background

Treatment decision for recurrent symptomatic brain metastases (BM) is challenging with scarce data regarding surgical resection. We therefore evaluated the efficacy of surgery for pretreated, recurrent BM in a comprehensive multidisciplinary treatment setting.

Methods

In a retrospective single center study, patients were analyzed, who underwent surgical resection of recurrent BM between 2007 and 2019. Intracranial event-free survival (EFS) and overall survival (OS) were evaluated by Kaplan-Maier and Cox regression analysis.

Results

We included 107 patients with different primary tumor entities and individual previous treatment for BM. Primary tumors comprised non-small cell lung cancer (NSCLC) (37.4%), breast cancer (19.6%), melanoma (13.1%), gastro-intestinal cancer (10.3%) and other, rare entities (19.6%). The number of previous treatments of BM ranged from one to four; the adjuvant treatment modalities comprised: none, focal or whole brain radiotherapy, brachytherapy and radiosurgery. The median pre-operative Karnofsky Performance Score (KPS) was 70% (range 40–100) and improved to 80% (range 0-100) after surgery. The complication rate was 26.2% and two patients died during the perioperative period. Sixty-seven (62.6%) patients received postoperative local radio-oncologic and/or systemic therapy. Median postoperative EFS and OS were 7.1 (95%CI 5.8–8.2) and 11.1 (95%CI 8.4–13.6) months, respectively. The clinical status (postoperative KPS ≥ 70 (HR 0.27 95%CI 0.16–0.46; p < 0.001) remained the only independent factor for survival in multivariate analysis.

Conclusions

Surgical resection of recurrent BM may improve the clinical status and thus OS but is associated with a high complication rate; therefore a very careful patient selection is crucial.

Treatment Algorithm for Cancerous Wounds: A Systematic Review

BACKGROUND

In advanced cancer stage the incidence of cancerous wounds is about 5%, and the estimated life expectancy is not more than 6 to 12 months. Without interdisciplinary and individualized treatment strategy, symptoms progress, and adversely influence quality of life.

METHODS

Authors collected different treatment algorithms for cancerous wound published by wide scale of medical expertise, and summarized surgical, oncological, radiation oncological, nursing and palliative care aspects based on radiological information.

RESULTS

Interdisciplinary approach with continuous consultation between various specialists can solve or ease the hopeless cases.

CONCLUSIONS

This distressing condition needs a comprehensive treatment solution to alleviate severe symptoms. Non-healing fungating wounds without effective therapy are severe socio-economic burden for all participants, including patients, caregivers, and health services. In this paper authors collected recommendations for further guideline that is essential in the near future.

Psychometric properties of patient-reported outcome measures for dysphagia in head and neck cancer: a systematic review protocol using COSMIN methodology

BACKGROUND

Dysphagia (swallowing difficulty) is one of the most common and debilitating sequelae of head and neck cancer (HNC). Patient-reported outcome measures (PROMs) are a fundamental component of dysphagia outcomes evaluation, as they inform treatment consequences that cannot be captured by objective clinician measures. Many PROMs for dysphagia in HNC are available, but their validity is unclear. As a consequence, the selection of the most appropriate PROM for dysphagia in HNC is complex and often based on the clinician's personal preferences, rather than on valid psychometric properties. This protocol describes a systematic review aiming at (1) identifying PROMs specific to dysphagia symptoms, swallowing functional status, swallowing-related health status, and swallowing-related quality of life in HNC, (2) mapping them to our conceptual framework of dysphagia-related PROs, and (3) appraising their psychometric properties using the Consensus Based Standards for the Selection of Health Measurement Instrument (COSMIN) methodology.

METHODS

Six electronic databases will be searched from inception to December 2020 for all primary studies in any language and design detailing PROM development, reliability, validity, feasibility, interpretability, and/or cross-cultural adaptation. Eligibility criteria will target PROMs for patients with HNC (≥ 90% of the study sample) with ≥ 20% of their items pertaining to swallowing. Two independent raters will screen abstract and full texts and a third rater will resolve discrepancies. Data will be extracted on study, sample and PROM characteristics, and results of psychometric testing. PROMs will be mapped to our conceptual framework. The methodological quality of included PROMs and their psychometric properties will be appraised using the COSMIN risk of bias checklist and evidence will be summarized using a modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

DISCUSSION

This systematic review will provide a summary of existing dysphagia-related PROMs for people with HNC and a comprehensive account of their psychometric properties. We will provide recommendations on PROMs selection which will aid healthcare professionals to the most appropriate PROM based on its validity, reliability, feasibility, interpretability and suitability for clinical and research settings. Further recommendations will be made on areas of measurement property requiring further testing.

Exploring Noona Using Passively-Collected Data and Satisfaction/Loyalty Ratings

Background

Electronic patient-reported outcomes’ real time communication of treatment-related symptoms is increasingly associated with better outcomes including longer survival and less health care resource use, but the primary method of collecting this information, static questionnaires, has not evolved.

Objective

The aim of this paper is to describe the use of Noona’s three methods of communicating treatment-related symptoms, which are as follows: (1) Noona symptom questionnaires (NSQ), which incorporate branching logic; (2) a diary; and (3) secure messaging, the last two of which have NSQ reporting functionality. It also aims to explore, using multivariable analyses, whether patients find value using these features.

Methods

Noona users (N=1081) who have an active account for more than 30 days, who responded to the satisfaction/loyalty item, and who were undergoing active cancer treatment (systemic or radiotherapy) in the United States were included in this study. All study data were collected via software embedded within Noona code. This includes metadata, patient activities (measured in clicks), and responses to a satisfaction/loyalty question (“How likely are you to recommend Noona to another patient”) displayed on the Noona home page.

Results

Noona users expressed a high degree of satisfaction/loyalty when asked to rate how likely they would recommend Noona to another patient. Multivariable analyses indicate small but significant effects for some of the analyses. Use of NSQs were significantly related to satisfaction/loyalty, users of NSQs had significantly higher satisfaction/loyalty than those who did not use any, and secure communication use was significantly higher for those who rated the app highly compared to those who did not. These relationships will likely be further explicated with the use of satisfaction/loyalty questions that focus specifically on feature use.

Conclusions

Noona is well liked by respondents, and exploratory multivariable analyses demonstrate the potential for using passively and minimally invasive data to demonstrate value.

A phase I/II study of acute and late physician assessed and patient-reported morbidity following whole pelvic radiation in high-risk prostate cancer patients

BACKGROUND

The aim of this study was to assess acute and late morbidity measured by the physician and patient-reported outcomes (PROs) in high-risk prostate cancer (PC) patients receiving whole pelvic intensity-modulated radiotherapy (IMRT) in the setting of a national clinical trial.

MATERIAL AND METHODS

A total of 88 patients with adenocarcinoma of the prostate and high-risk parameters were enrolled from 2011 to 2013. All patients received 78 Gy in 39 fractions of IMRT delivering simultaneous 78 Gy to the prostate and 56 Gy to the seminal vesicles and lymph nodes. Physician-reported morbidity was assessed by CTCAE v.4.0. PROs were registered for gastro-intestinal (GI) by the RT-ARD score, genito-urinary (GU) by DAN-PSS, sexual and hormonal by EPIC-26, and quality of life (QoL) by EORTC QLQ-C30.

RESULTS

Median follow-up (FU) time was 4.6 years. No persistent late CTCAE grade 3+ morbidity was observed. Prevalence of CTCAE grade 2+ GI morbidities varied from 0 to 6% at baseline throughout FU time, except for diarrhea, which was reported in 19% of the patients post-RT. PROs revealed increased GI morbidity (≥1 monthly episode) for "rectal urgency", "use of pads", "incomplete evacuation", "mucus in stool" and "bowel function impact on QoL" all remained significantly different (p < .05) at 60 months compared to baseline. CTCAE grade 2+ GU and sexual morbidity were unchanged. GU PROs on obstructive and irritative GU items (≥daily episode) increased during RT and normalized at 24 months. No clinically significant differences were found in sexual, hormonal, and QoL scores compared to baseline.

CONCLUSIONS

Whole pelvic RT resulted in a mild to the moderate burden of late GI morbidities demonstrated by a relatively high prevalence of PROs. Whereas, physician-assessed morbidity revealed a low prevalence of late GI morbidity scores. This emphasizes the importance of using both PROs and physician-reported scoring scales when reporting late morbidity in clinical trials.

Patient-reported outcomes version of the common terminology criteria for adverse events and quality-of-life linear analogue self-assessment in breast cancer patients receiving radiation therapy: single-institution prospective registry

Purpose/objectives

We sought to investigate the impact of patient-reported outcomes version of the common terminology criteria for adverse events (PRO-CTCAE) on overall quality-of-life (QOL) employing linear analogue self-assessment (LASA) in breast cancer (BC) patients undergoing radiation therapy (RT).

Materials/methods

All patients treated with RT for BC with curative intent from 2015 to 2019 at our institution were included. Breast specific PRO-CTCAE and overall QOL LASA questionnaires were administered at baseline, end-of-treatment, 3, 6, 12 months, and then annually. Minimal clinically important difference in overall QOL was a 10-point change in LASA. Hypofractionation was any treatment > 2 Gy per fraction. Mixed models for repeated measures were used to determine the association of PRO-CTCAE and overall QOL LASA.

Results

Three hundred thirty-one (331) patients with a median follow-up of 3.1 years (range 0.4–4.9) were included. Average overall QOL LASA scores were 78.5 at baseline, 79.8 at end-of-treatment, 79.8 at 3 months, 77.1 at 6 months, 79.4 at 12 months, and 79.7 at 24 months. On univariate analysis, patients reporting a grade ≥ 3 PRO-CTCAE had, on average, a 10.4-point reduction in overall LASA QOL (p < 0.0001). On multivariate analysis, not being treated with hypofractionation and higher BMI were predictive for worse overall LASA QOL with a 10-point reduction in LASA for patients reporting a grade ≥ 3 PRO-CTCAE (p < 0.0001).

Conclusions

Patients reporting a grade ≥ 3 PRO-CTCAE experienced statistically significant and clinically meaningful deterioration in overall QOL LASA. Hypofractionation improved QOL while higher BMI predicted for worse QOL. PRO-CTCAE should be integrated into future clinical trials.

Patient-reported distress as an early warning sign of unmet palliative care needs and increased healthcare utilization in patients with advanced cancer

INTRODUCTION

Cancer patients' sources of distress are often unaddressed, and patient-reported distress data could be utilized to identify those with unmet and impending care needs. We explored the association between moderate/severe distress and healthcare utilization in a large sample of non-small cell lung cancer (NSCLC) and non-colorectal gastrointestinal cancer patients.

METHODS AND MATERIALS

Adult patients treated between July 2013 and March 2019. Data from the NCCN Distress Thermometer (DT) and the accompanying "Problem List" were extracted from the EHR. A DT score of ≥ 4 indicates "actionable distress." Statistical analysis was performed using descriptive analysis for patient characteristics, clinical outcomes, and sources of distress. Generalized linear mixed models were fit to determine the relationship between distress and healthcare utilization (hospitalization, emergency department (ED) visit, or both).

RESULTS

The ten most frequently reported problems were from the Physical and Emotional domains of the Problem List. Distress was mostly related to physical symptoms (pain, fatigue) and emotional issues (worry, fears, sadness, nervousness). Patients with actionable distress generally reported more problems across all their visits. Actionable distress was associated with higher odds of the composite outcome measure of hospitalization or visiting the ED, within both the next 3 months (OR = 1.37; 95% CI = 1.19, 1.58; p < 0.001) and 6 months (OR = 1.19; 95% CI = 1.03, 1.37; p = 0.019).

CONCLUSION

Patients with significant distress had marked utilization of ED and inpatient services. DT scores are a source of untapped data in the EHR that can highlight patients in need of intervention, including palliative care and cancer support services.

Preventing taxane-related peripheral neuropathy, pain and nail toxicity: a prospective self-controlled trial comparing hilotherapy with frozen gloves in early breast cancer

PURPOSE

The prevention of taxane-related toxicities at the extremities is highly important for patients' treatment and quality-of-life. Several studies endorse hand/foot-cooling using frozen gloves as a prophylactic intervention. Unlike frozen gloves, hilotherapy produces cooling at a constant temperature. Comparative data with frozen gloves are unavailable.

METHODS

This prospective self-controlled study explores the efficacy of hilotherapy at the right hand and foot compared to frozen gloves at the left in patients with early breast cancer treated with weekly paclitaxel 80 mg/m² or three-weekly docetaxel 75 mg/m². Patient-reported outcomes were collected at baseline, 6, 12, 18 and 24 weeks after the start of treatment. Primary and secondary endpoints were the incidence of any-grade and ≥ grade 2 side-effects (peripheral neuropathy, pain and nail toxicities), and perceived comfort of both interventions.

RESULTS

Sixty-two patients participated. The incidence of any-grade side-effects was similar on both sides, 85.5% with hilotherapy and 90.3% with frozen gloves (p = 1.000). The incidence of ≥ grade 2 side-effects at the extremities was significantly lower with hilotherapy: 43.6% compared to 61.3% with frozen gloves (p = 0.013). Perceived comfort was significantly better for hilotherapy than for frozen gloves (p < 0.0001).

CONCLUSIONS

Compared to frozen gloves, continuous cooling of hands and feet using hilotherapy produces better prevention of ≥ grade 2 patient-reported side-effects at the extremities (peripheral neuropathy, pain and nail toxicities). Perceived comfort was significantly better for hilotherapy. From a clinical and patient perspective, hilotherapy is a better alternative for preventing clinically significant taxane-related side-effects.

Place of patient-reported outcomes & experiences measurements (PROMS/PREMS) in the assessment and pricing of Health technologies in France

In the context of health technologies assessment, patient-reported outcome measures (PROMs) have become assessment criteria that are expected by evaluation agencies along with the other usual clinical criteria. PROMs instruments measure all aspects of patient experience in connection with their health: symptoms, activities of daily living (physical function, sleep, etc.), various aspects of health-related quality of life (QoL), compliance, global impression of change in wellbeing. PROMs are useful both as 1) a primary or secondary efficacy endpoints, and 2) a tolerability criterion to supplement vigilance data reported by clinicians. Measurement of PROMs must be subject to methodological rigor that is identical to that of other assessment criteria measured by an observer. Scales must be validated, suitable for the objective, and where possible specific to a disease. In addition to standard measures of quality of life, PROMs are taken into consideration in the assessments performed by the HAS, even if their impact on the conclusions is difficult to isolate, as assessments are multifactorial and take into account all data available with regard to the medical context. The CEPS will indirectly take into account PROMs in the fixing of the price or tariff only if they have contributed to the award of the ASA/ASMR by the ad hoc committee of the HAS. The working group has formulated three recommendations which aim to further the implementation of patient-reported outcome measures: (1) Better information for all parties involved in a dossier for technology assessment, (2) Systematization of the collection of PROMs for evaluation of health products, (3) Improved quality of dossiers thanks to the use of relevant and validated tools.

Symptoms reported by gastrointestinal stromal tumour (GIST) patients on imatinib treatment: combining questionnaire and forum data

PURPOSE

Treatment with the tyrosine kinase inhibitor (TKI) imatinib in patients with gastrointestinal stromal tumours (GIST) causes symptoms that could negatively impact health-related quality of life (HRQoL). Treatment-related symptoms are usually clinician-reported and little is known about patient reports. We used survey and online patient forum data to investigate (1) prevalence of patient-reported symptoms; (2) coverage of symptoms mentioned on the forum by existing HRQoL questionnaires; and (3) priorities of prevalent symptoms in HRQoL assessment.

METHODS

In the cross-sectional population-based survey study, Dutch GIST patients completed items from the EORTC QLQ-C30 and Symptom-Based Questionnaire (SBQ). In the forum study, machine learning algorithms were used to extract TKI side-effects from English messages on an international online forum for GIST patients. Prevalence of symptoms related to imatinib treatment in both sources was calculated and exploratively compared.

RESULTS

Fatigue and muscle pain or cramps were reported most frequently. Seven out of 10 most reported symptoms (i.e. fatigue, muscle pain or cramps, facial swelling, joint pain, skin problems, diarrhoea, and oedema) overlapped between the two sources. Alopecia was frequently mentioned on the forum, but not in the survey. Four out of 10 most reported symptoms on the online forum are covered by the EORTC QLQ-C30. The EORTC-SBQ and EORTC Item Library cover 9 and 10 symptoms, respectively.

CONCLUSION

This first overview of patient-reported imatinib-related symptoms from two data sources helps to determine coverage of items in existing questionnaires, and prioritize HRQoL issues. Combining cancer-generic instruments with treatment-specific item lists will improve future HRQoL assessment in care and research in GIST patients using TKI.

Serious Adverse Events Reporting in Phase III Randomized Clinical Trials of Colorectal Cancer Treatments: A Systematic Analysis

Objective: The occurrence, development, and prognosis of serious adverse events (SAEs) associated with anticancer drugs in clinical trials have important guiding significance for real-world clinical applications. However, to date, there have been no studies investigating SAEs reporting in randomized clinical trials of colorectal cancer treatments. This article systematically reviewed the SAEs reporting of phase III randomized clinical trials of colorectal cancer treatments and analyzed the influencing factors. Methods: We reviewed all articles about phase III randomized clinical trials of colorectal cancer treatments published in the PubMed, Embase, Medline, and New England Journal of Medicine databases from January 1, 1993, to December 31, 2018, and searched the registration information of clinical trials via the internet sites such as "clinicaltrials.gov". We analyzed the correlation between the reported proportion (RP) of SAEs in the literature and nine elements, including the clinical trial sponsor and the publication time. Chi-square tests and binary logistic regression were used to identify the factors associated with improved SAEs reports. This study was registered on PROSPERO. Results: Of 1560 articles identified, 160 were eligible, with an RP of SAEs of 25.5% (41/160). In forty-one publications reporting SAEs, only 14.6% (6/41) described the pattern of SAEs in detail. In clinical trials sponsored by pharmaceutical companies, the RP of SAEs was significantly higher than that in those sponsored by investigators (57.6 versus 20.7%, p < 0.001). From 1993 to 2018, the RP of SAEs gradually increased (none (0/6) before 2000, 17.1% (12/70) from 2000 to 2009, and 34.5% (29/84) after 2009). The average RP of SAEs published in the New England Journal of Medicine (N Engl J Med), the Lancet, the Journal of the American Medical Association (JAMA), the Lancet Oncology (Lancet Oncol), and the Journal of Clinical Oncology (J Clin Oncol) was significantly higher than that published in other journals (31.9 versus 16.7%, p = 0.030). In the clinical trials referenced by clinical guidelines, the RP of SAEs was higher than that in non-referenced clinical trials (32.0 versus 15.9%, p = 0.023). Binary logistic regression analysis showed that pharmaceutical company sponsorship, new drug research, and sample size greater than 1000 were positive influencing factors for SAEs reporting. Conclusion: Although the RP of SAEs increased over time, SAEs reporting in clinical trials needs to be further improved. The performance, outcomes and prognosis of SAEs should be reported in detail to guide clinical practice in the real world.

Pneumonitis and fibrosis after breast cancer radiotherapy: occurrence and treatment-related predictors

BACKGROUND

Radiation pneumonitis (RP) and radiation fibrosis (RF) are common side effects after breast cancer (BC) radiotherapy (RT). However, there is a great variation in the frequency of RP and RF. This study presents the occurrence of- and the treatment-related predictors for RP and RF. Further, physician- and patient-reported pulmonary symptoms during the first year after postoperative RT for BC are demonstrated.

MATERIALS AND METHODS

From 2007 to 2008, 250 BC patients referred for postoperative RT were included in a prospective cohort study and followed during the first year after RT. High-resolution computed tomography of the lungs and symptom registration were performed before RT and 3, 6, and 12 months after RT. Patient-reported symptoms were registered by standard quality of life questionnaires. Logistic regression analyses were applied to estimate treatment-related predictors for radiological RP (rRP), clinical RP (cRP), radiological RF (rRF), and clinical RF (cRF).

RESULTS

The occurrence of rRP and cRP at three months was 78% and 19%, while 12 months after RT rRF and cRF was 89% and 16%, respectively; all reported as grade 1. In multivariable analyses, mastectomy predicted cRP at three months (OR = 2.48, p = .03) and cRF at six months, ipsilateral lung volume receiving 20 Gray or more (V20), V30, and mean lung dose (MLD) predicted rRP at six months (OR = 1.06, p = .0003; OR = 1.10, p = .001; and OR = 1.03, p = .01, respectively). Endocrine treatment predicted cRF at 12 months (OR = 2.48, p = .02). Physicians reported significant more dyspnea at 3 months (p = .003) and patients reported 'a little dyspnea' more at 3 and 12 months compared to baseline (p = .007).

CONCLUSION

RP and RF are prevalent in the first year after BC radiation. Mastectomy predicted cRP at three months. V20, V30, D25, and MLD predicted rRP at 6 months, and endocrine treatment predicted cRF at 12 months. Patients and physicians reported dyspnea differently.

The efficacy and tolerability of ultra-hypofractionated radiotherapy in low-intermediate risk prostate cancer patients: single center experience

BACKGROUND

We aimed to investigate the efficacy and tolerability of ultra-hypofractionated radiotherapy (UHRT) in the treatment of low and intermediate-risk prostate cancer patients.

METHODS

This retrospective study was conducted using data derived from 44 patients who underwent UHRT, and toxicity assessment and clinical response were investigated. Treatment consisted of 35-36.25 Gy in 5 fractions using stereotactic ablative radiotherapy (SABR) with the Linac-based delivery system.

RESULTS

The median duration of follow-up was 52 months (8-68 months) and the median age was 71.5 years (54-85 years). Twenty-seven patients were assigned as intermediate-risk, whereas 17 patients had low-risk. The 5-year overall survival rate was 87.8%, while the 5-year biochemical recurrence-free survival (bRFS) rate was 97.4%. Acute grade 3 genitourinary (GU) side effect was not observed in any patient, whereas acute gastrointestinal (GI) system grade 3 side effect was seen in 6.8% of the patients. Late grade 3 GU and GI side effects were seen in 4.6% and 6.8% of the patients, respectively. In patients with planning target volume (PTV) ≥85 ml, acute grade ≥2 GU side effects were more common (p=.034).

CONCLUSION

Our data demonstrated that UHRT administered with volumetric arc therapy (VMAT) can be recommended for selected patients with low-intermediate risk prostate cancer. Further prospective, multicentric, controlled trials on larger series are warranted to reach more accurate conclusions.

Nursing Management and Adverse Events in Thyroid Cancer Treatments with Tyrosine Kinase Inhibitors. A Narrative Review

Simple Summary

Tyrosine kinase inhibitors are an effective and promising therapy in the treatment of advanced differentiated medullary thyroid cancers. The prevention and management of new adverse events of these drugs are important to keep patients on their treatment course, avoiding drug discontinuation or interruption, and are associated with a faster recovery of the disease. The contribution of a multidisciplinary team of healthcare professionals optimizes the management of adverse events, maximizing the benefits and reducing the risks of treatment, consequently improving the quality of life of patients.

Abstract

Background: The advent of multikinase inhibitors has changed the treatment of advanced, metastatic, unresectable thyroid cancers, refractory to available treatments. These drugs cause new adverse events that should be prevented and treated for long periods, and sometimes beyond their discontinuation. The purpose of this narrative review was the description, prevention, and nursing management of the most frequent adverse events of locally advanced or metastatic differentiated thyroid cancer with sorafenib and lenvatinib, and medullary Thyroid cancer with vandetanib and cabozantinib treatment. Methods: A narrative literature review. Results: Studies included in this narrative review suggest that over 90% of patients treated with tyrosine kinase inhibitors experience at least 1 adverse event of any grade affecting their quality of life. Patients treated with tyrosine kinase inhibitors experienced at least one adverse event at any grade in ≥90% of cases, with a higher incidence in the first 6–8 weeks of treatment. The most frequent adverse events that can affect a patients’ quality of life are dermatological, gastrointestinal, cardiovascular, and metabolic. Conclusions: Early assessment of risk factors and identification of adverse events can help nurses support these patients throughout their clinical-therapeutic pathway, increasing the benefits of treatment and reducing reduction/discontinuation.

Association Between Physician and Patient Reported Symptoms in Patients Treated with Definitive Radiotherapy for Locally Advanced Lung Cancer in a Statewide Consortium

INTRODUCTION

Little data have been reported about the patient experience during curative radiotherapy for lung cancer in routine clinical practice, or how this relates to treatment toxicity reported by clinicians. The purpose of this study was to compare clinician-reported adverse events (AEs) with patient-reported outcomes (PROs) including both specific symptoms/side effects as well as overall quality of life (QOL) during and after definitive radiotherapy (RT) for locally advanced lung cancer (LALC) in a large statewide cohort.

METHODS AND MATERIALS

Patient-reported outcomes (PROs) were prospectively collected from patients treated with definitive radiotherapy for LALC at 24 institutions within the XXXX Radiation Oncology Quality Consortium between 2012-2018 using the Functional Assessment of Cancer Therapy Trial Outcome Index (FACT-TOI). Physicians prospectively recorded adverse events (AEs) using CTCAE version 4.0. Patient-reported quality of life (QOL) changes from baseline were assessed during and after radiotherapy using the FACT-TOI. Spearman correlation coefficients were calculated for AEs and similar PROs, and multivariable analysis was used to assess associations with QOL.

RESULTS

1361 patients were included and 53% of respondents reported clinically meaningful declines in QOL at the end of RT. Correlation between clinician-reported esophagitis and patient-reported trouble swallowing was moderate (R=0.67) while correlations between clinician-reported pneumonitis and patient-reported shortness of breath (R=0.13) and cough (R=0.09) were weak. Clinician-reported AEs were significantly associated with clinically meaningful declines inpatient-reported QOL, with R=-0.46 for a summary AE-score. QOL was more strongly associated with fatigue (R=-0.41) than lung-specific AEs.

CONCLUSIONS

AEs are associated with clinically meaningful declines in QOL during and after RT for LALC, but associations between AEs and QOL are only modest. This highlights the importance of PRO data, and future research should assess whether earlier detection of PRO changes could allow for interventions that reduce the frequency of treatment-related clinically meaningful declines in QOL.

Rheumatic Manifestations and Diseases From Immune Checkpoint Inhibitors in Cancer Immunotherapy

Immune checkpoint inhibitors (ICIs), which can enhance antitumor immunity and inhibit cancer growth, have revolutionized the treatment of multiple cancers and dramatically decreased mortality. However, treatment with ICIs is directly associated with immune-related adverse events (irAEs) because of inflammation in off-target organs and autoimmunity resulting from non-specific immune activation. These irAEs can cause rheumatic diseases and manifestations such as inflammatory arthritis, polymyalgia rheumatica, myositis, vasculitis, Sicca and Sjogen's syndrome, and systemic lupus erythematosus. Early diagnosis and treatment of these adverse events will improve outcomes and quality of life for cancer patients. The treatment of rheumatic diseases induced by ICIs requires multidisciplinary cooperation among physicians. Furthermore, the underlying mechanisms are not fully understood and it is difficult to predict and evaluate these side effects precisely. In this review, we summarize available studies and findings about rheumatic irAEs, focusing mainly on the clinical manifestations, epidemiology, possible mechanisms, and guiding principles for treating these irAEs.

Best regimens for treating chemo-naïve incurable squamous non-small cell lung cancer with a programmed death-ligand 1 tumor proportion score of 1%-49%: A network meta-analysis

Background

Non‐small cell lung cancer (NSCLC) is the leading cause of cancer‐related mortality worldwide. It is advisable to select the appropriate treatment based on characteristics of the cancer such as pathology, mutations, and programmed death‐ligand 1 (PD‐L1) levels. In this study, by remarking squamous NSCLC with low PD‐L1 expression without mutations, we investigated the efficacy and safety of regimens that included molecularly targeted drugs such as immune checkpoint inhibitors (ICIs) through a network meta‐analysis.

Methods

Databases were searched systematically to identify appropriate articles, in which randomized trials with incurable squamous NSCLC were described. Suitable studies were manually checked by two reviewers. A random model network meta‐analysis was conducted, in which the primary outcome was the overall survival rate.

Results

We identified 48 studies, which included 16 391 patients. When a platinum + third‐generation cytotoxic agent regimen (platinum regimen) was a reference, the platinum regimen + pembrolizumab (Pemb) yielded the best results in regard to the overall survival rate when compared with chemotherapy (hazard ratio [HR] = 0.57, 95% confidence interval [CI] = 0.36–0.90, p = 0.016) followed by the platinum regimen + nivolumab (Niv) + ipilimumab (Ipi) (HR = 0.61, 95% CI = 0.44–0.84, p = 0.003). However, the efficacy of ICI monotherapy was not statistically different from that of the platinum regimen.

Conclusions

The combination therapies, which were the platinum regimen + Pemb and the platinum regimen + Niv + Ipi, rather than ICI monotherapy were effective first‐line agents for treating squamous NSCLC with low PD‐L1 levels.

Relationship between Serum Bortezomib Concentration and Emergence of Diarrhea in Patients with Multiple Myeloma and/or AL Amyloidosis

(1) Background: multiple myeloma patients have benefited from bortezomib therapy, though it has often been discontinued owing to diarrhea. The objective of this study was to verify serum bortezomib concentration in the emergence of diarrhea. (2) Methods: this prospective, observational case-control, and monocentric study was performed with an approval by the Ethics Committee of Kumamoto University Hospital in 2015 (No. 1121) from February 2015 to April 2017. (3) Results: twenty-four patients with bortezomib therapy were recruited; eight patients (33.3%) developed diarrhea at day 3 as median. Median measured trough bortezomib concentration at 24 h after first or second dose for patients with or without diarrhea was 0.87 or 0.48 ng/mL, respectively (p = 0.04, Wilcoxon signed rank test). Receiver operation characteristic (ROC) analysis produced the cut-off concentration of 0.857 ng/mL (area under the ROC curve of 0.797, sensitivity of 0.625, specificity of 0.875). The survival curves between patients with and without diarrhea were similar (p = 0.667); those between patients with higher and lower concentration than median value (0.61 ng/mL) were also similar (p = 0.940). (4) Conclusions: this study indicated the possible involvement of serum bortezomib concentration in the emergence of diarrhea in bortezomib therapy in patients with multiple myeloma.

Primary or adjuvant chemoradiotherapy for cervical cancer with intraoperative lymph node metastasis - A review

Upon discovery of lymph node metastasis during radical hysterectomy with pelvic lymphadenectomy in early-stage cervical cancer, the gynaecologist may pursue one of two treatment strategies: abandonment of surgery followed by primary (chemo)radiotherapy (PRT) or completion of radical hysterectomy, followed by adjuvant (chemo)radiotherapy (RHRT). Current guidelines recommend PRT over RHRT, as combined treatment is presumably associated with increased morbidity. However, this review of literature suggests there are no significant differences in survival and recurrence and total proportions of adverse events between treatment strategies. Additionally, both strategies are associated with varying types of adverse events, and affect quality of life and sexual functioning differently, both in the short and long term. Although total proportions of adverse events were comparable between treatment strategies, lower extremity lymphoedema was reported more often after RHRT and symptom experience (e.g. distress from bladder or bowel problems) and sexual dysfunction more often after PRT. As reporting of adverse events, quality of life and sexual functioning were not standardised across the articles included, and covariate adjustment was not conducted in most of the analyses, comparability of studies is hampered. Accumulating retrospective evidence suggests no major differences on oncological outcome and morbidity after PRT and RHRT for intraoperatively discovered lymph node metastasis in cervical cancer. However, conclusions should be considered cautiously, as all studies were of retrospective design with small sample sizes. Still, treatment strategies seem to affect adverse events, quality of life and sexual functioning in different ways, allowing room for shared decision-making and personalised treatment.

A Fructo-Oligosaccharide Prebiotic Is Well Tolerated in Adults Undergoing Allogeneic Hematopoietic Stem Cell Transplantation: A Phase I Dose-Escalation Trial

Alterations of the gut microbiota after allogeneic hematopoietic cell transplantation (allo-HCT) are a key factor in the development of transplant-related complications such as graft-versus-host disease (GVHD). Interventions that preserve the gut microbiome hold promise to improve HCT-associated morbidity and mortality. Murine models demonstrate that prebiotics such as fructo-oligosaccharides (FOSs) may increase gut levels of short-chain fatty acids (SCFAs) such as butyrate and consequently induce proliferation of immunomodulatory FOXP3+CD4+ regulatory T cells (Tregs), which impact GVHD risk. We conducted a pilot phase I trial to investigate the maximum tolerated dose of FOS in patients undergoing reduced-intensity allo-HCT (n = 15) compared with concurrent controls (n = 16). We administered the FOS starting at pretransplant conditioning and continuing for a total of 21 days. We characterized the gut microbiome using shotgun metagenomic sequencing, measured stool short-chain fatty acids (SCFAs) using liquid chromatography-mass spectrometry, and determined peripheral T cell concentrations using cytometry by time-of-flight. We found that FOS was safe and well-tolerated at 10 g/d without significant adverse effects in patients undergoing allo-HCT. Community-level gut microbiota composition differed significantly on the day of transplant (day 0) between patients receiving FOS and concurrent controls; however, FOS-associated alterations of the gut microbiota were not sustained after transplant. Although the impact of FOS was fleeting, transplantation itself impacted a substantial number of taxa over time. In our small pilot trial, no significant differences were observed in gut microbial metabolic pathways, stool SCFAs, or peripheral Tregs, although Tregs trended higher in those patients who received FOS. A marker of CD4+ T cell activation (namely, CTLA4+) was significantly higher in patients receiving FOS, whereas a non-significant trend existed for FOP3+CD4+ Treg cells, which were higher in those receiving FOS compared with controls. FOS is well tolerated at 10 g/d in patients undergoing reduced-intensity allo-HCT. Although the alterations in gut microbiota and peripheral immune cell composition in those receiving FOS are intriguing, additional studies are required to investigate the use of prebiotics in HCT recipients.
