Clinical characteristics and prognostic implications of immune-related hepatitis in patients with advanced non-small cell lung cancer treated with immune checkpoint inhibitors: a retrospective study

Background

With the widespread use of immune checkpoint inhibitors (ICIs), patients inevitably experience immune-related adverse events (irAEs). Therefore, the study was conducted on the clinical characteristics and outcomes of patients with non-small cell lung cancer (NSCLC) with immune-related hepatitis (ir-hepatitis).

Methods

We identified patients with advanced NSCLC who developed ir-hepatitis after immunotherapy between June 2016 and December 2022. Their irAEs were categorized according to the Common Terminology Criteria for Adverse Events version 4.03 (CTCAE 4.03). Kaplan-Meier curves and log-rank tests were used to analyze survival.

Results

A total of 35 patients were enrolled in the study. The numbers of mild (grade 1-2) and severe (grade 3-4) ir-hepatitis cases were 13 (grade 1, 3; grade 2, 10) and 22 (grade 3, 17; grade 4, 5), respectively. The median onset time of ir-hepatitis was 1.6 months. The median progression-free survival (mPFS) was 8.3 months. PFS differed between patients with early ir-hepatitis developing within two treatment cycles and those with ir-hepatitis developing more than two treatment cycles (5.5 vs. 12.7 months, P=0.004). Patients with severe rather than mild ir-hepatitis tended to poorer PFS survival (5.8 vs. 11.2 months, P=0.130). The appearance of ir-hepatitis within two treatment cycles (P=0.002) and higher severity grades of ir-hepatitis (P=0.005) were independent risk factors for PFS.

Conclusions

Early and severe ir-hepatitis are associated with worse survival benefits, which still required more basic and perspective studies.

Raising awareness of immune-related side effects in oncological patients under palliative care: a report of two cases

BACKGROUND

Immune checkpoint inhibitors (ICI) have emerged as a successful treatment option for diverse cancer entities. However, ICI therapy can be associated with immune-related adverse events (irAE) that can affect any organ system. These side effects can be severe, irreversible and sometimes even fatal. Due to the presentation as diverse and often unspecific clinical patterns, end-of-life care concepts may be pursued hastily suspecting disease progression in oncological patients receiving palliative care (PC).

CASE DESCRIPTION

This report describes two cancer patients whose symptom burden was caused by such irAEs: One patient with metastatic cutaneous squamous cell carcinoma (SCC) presenting with disorientation and urinary incontinence, another patient with metastatic melanoma presenting with a sudden and unspecific deterioration of the overall condition. After imaging and blood sampling, an encephalitis and an immune-mediated diabetes mellitus were diagnosed. After treatment with corticosteroids and hydration alongside insulin substitution both patients experienced a complete symptom relief.

CONCLUSIONS

We aim to emphasize the importance of continued collaboration between primary care givers and PC teams as well as raise awareness among PC providers of severe immune-related side effects in cancer patients receiving ICI. Especially within this patient cohort, PC teams play a crucial part in detecting possible irAEs, which resolve in the majority of cases when receiving early guideline-adapted treatment.

A pilot study of anlotinib with third-generation epidermal growth factor receptor tyrosine kinase inhibitors in untreated EGFR-mutant patients with advanced non-small cell lung cancer

Background

In recent years, osimertinib, a third-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), has been recommended as a first-line treatment for EGFR-mutant advanced non-small cell lung cancer (NSCLC). A phase III study (AENEAS) to assess the efficacy and safety of aumolertinib, another third-generation EGFR-TKI, vs. gefitinib as a first-line treatment in patients with locally advanced or metastatic NSCLC harboring EGFR mutations has also achieved positive results. Despite the improvements in progression-free survival (PFS) and overall survival (OS) of third- vs. first-generation EGFR-TKIs, combined treatment strategies to postpone drug resistance and further prolong survival benefits remain to be explored.

Methods

We conducted a nonrandomized phase II trial (ChiCTR2000035140) of an oral multitarget antiangiogenic TKI (anlotinib) with third-generation EGFR-TKIs (osimertinib or aumolertinib) in untreated patients with EGFR mutation and advanced NSCLC. Anlotinib and the third-generation EGFR-TKIs were orally administrated (anlotinib at a dose of 12 mg once every other day and osimertinib at 80 mg once daily or aumolertinib at 110 mg once daily). The primary end point of the study was the objective response rate (ORR). Secondary endpoints included the disease control rate (DCR), OS, PFS, and safety of the combined treatment.

Results

Enrollment was ceased due to treatment-related adverse events (trAEs) after 11 of 35 planned patients were treated. Among these 11 patients, two were lost to follow-up, and the treatment of five of the remaining nine patients was discontinued due to trAEs, including stomachache, rash, hyponatremia, pulmonary embolism, and interstitial pneumonia. AEs of grade 3 or worse were observed in five patients, but no treatment-related death occurred in these patients.

Conclusions

Combining anlotinib and third-generation EGFR-TKIs in untreated EGFR-mutant patients with advanced NSCLC demonstrated significantly increased toxicity, suggesting that the combined treatment strategy was an inappropriate therapeutic choice in this setting.

Adverse events of bevacizumab for triple negative breast cancer and HER-2 negative metastatic breast cancer: A meta-analysis

Background: Triple-negative breast cancer (TNBC) and HER-2 negative metastatic breast cancer (HER-2 negative MBC) are intractable to various treatment schemes. Bevacizumab as a novel anti-VEGF drug, its safety for these two high-risk breast cancers remains controversial. Therefore, we conducted this meta-analysis to assess the safety of Bevacizumab for TNBC and HER-2 negative MBC. Methods: We searched Medline, Embase, Web of science and Cochrane databases updated to 1 Oct 2022 for relevant randomized controlled trials (RCTs). In all, 18 RCTs articles with 12,664 female patients were included. We used any grade Adverse Events (AEs) and grade ≥3 AEs to assess the AEs of Bevacizumab. Results: Our study demonstrated that the application of Bevacizumab was associated with increased incidence of grade ≥3 AEs (RR = 1.37, 95% CI 1.30-1.45, Rate: 52.59% vs. 41.32%). Any grade AEs (RR = 1.06, 95% CI 1.04-1.08, Rate: 64.55% vs. 70.59%) did not show a significant statistical difference in both overall results and among the subgroups. In subgroup analysis, HER-2 negative MBC (RR = 1.57, 95% CI 1.41-1.75, Rate: 39.49% vs. 25.6%), dosage over 15 mg/3w (RR = 1.44, 95% CI 1.07-1.92, Rate: 28.67% vs. 19.93%) and endocrine therapy (ET) (RR = 2.32, 95% CI 1.73-3.12, Rate: 31.17% vs. 13.42%) were associated with higher risk of grade ≥3 AEs. Of all graded ≥3 AEs, proteinuria (RR = 9.22, 95%CI 4.49-18.93, Rate: 4.22% vs. 0.38%), mucosal inflammation (RR = 8.12, 95%CI 2.46-26.77, Rate: 3.49% vs. 0.43%), palmar-plantar erythrodysesthesia syndrome (RR = 6.95, 95%CI 2.47-19.57, Rate: 6.01% vs. 0.87%), increased Alanine aminotransferase (ALT) (RR = 6.95, 95%CI 1.59-30.38, Rate: 3.13% vs. 0.24%) and hypertension (RR = 4.94, 95%CI 3.84-6.35, Rate: 9.44% vs. 2.02%) had the top five risk ratios. Conclusion: The addition of Bevacizumab for TNBC and HER-2 negative MBC patients showed an increased incidence of AEs especially for grade ≥3 AEs. The risk of developing different AEs varies mostly dependent on the type of breast cancer and combined therapy.

Efficacy and safety of nimotuzumab combined with chemoradiotherapy in the treatment of locally advanced cervical cancer

Background

Platinum-based concurrent chemoradiotherapy (CCRT) is the primary treatment for locally advanced cervical cancer (LACC). Improving the efficacy of LACC treatment is the focus of clinical research, and nimotuzumab combined with CCRT is a new research direction. This retrospective study aimed to investigate the efficacy and safety of nimotuzumab combined with CCRT compared with CCRT alone for treating LACC.

Methods

Data from LACC patients treated at The Affiliated Hospital of Qingdao University from March 2017 to December 2019 were collected, and patients were assigned to either a nimotuzumab plus chemoradiotherapy (N + CCRT) group or a CCRT group. Baseline data were also collected. Patients were followed up every 3 to 6 months by imaging examination or telephone. The primary endpoints were overall survival (OS) and progression-free survival (PFS), and the secondary endpoints were complete response rate (CRR), objective response rate (ORR), and incidence of adverse events (AEs).

Results

A total of 120 patients (65 in the N + CCRT group and 55 in the CCRT group) were enrolled, which baseline data were no statistical difference between the two groups (P>0.05). In the N + CCRT group, the 1-, 2-, and 3-year cumulative survival rates were 98.46%, 95.38%, and 90.50%, respectively, and the 1-, 2-, and 3-year cumulative PFS rates were 89.23%, 83.08%, and 79.73%, respectively. The CRR was 86.15% (56/65), and the ORR was 92.31% (60/65). In the CCRT group, the 1-, 2-, and 3-year cumulative survival rates were 94.55%, 87.27%, and 78.18%, respectively, and the 1-, 2-, and 3-year cumulative PFS rates were 81.82%, 69.09%, and 59.69%, respectively. The CRR was 70.91% (39/55), and the ORR was 87.27% (48/55). The CRR (86.15% vs. 70.91%, P=0.040) and 3-year cumulative PFS rates (79.73% vs. 59.69%, P=0.039) were significantly higher in the N + CCRT group than in the CCRT group. The incidences of various AEs were from 5.45% to 95.38%, without significant difference in AEs between the two groups (P>0.05).

Conclusions

Nimotuzumab combined with CCRT enhanced the PFS and CRR of LACC patients and was well tolerated. The results can provide reference for clinical treatment of LACC.

Real-World Safety Profile of Biologics Used in Rheumatology: A Six-Year Observational Pharmacovigilance Study in the Calabria Region

Background: The introduction of biological agents into the clinical armamentarium has modified the management of moderate-severe inflammatory arthritis (IA). However, these drugs can lead to serious adverse events (SAEs) and unpredictable adverse events (AEs) that are difficult to detect in pre-marketing clinical trials. This pharmacovigilance project aimed to study the AEs associated with biologics use in rheumatology. Methods: The current investigation is a multicenter, prospective, observational cohort study based on the Calabria Biologics Pharmacovigilance Program. Patients treated with one biologic agent from January 2016 to January 2022 were enrolled. Results: Overall, 729 (86.3%) of a total of 872 patients did not develop AEs or SAEs, whereas 143 (16.4%) patients experienced at least one AE, of which 16 (1.8%) had at least one SAE. The most common AEs were administration site conditions followed by gastrointestinal, nervous system and skin disorders. We reported a total of 173 switches and 156 swaps. Switches mainly occurred for inefficacy (136; 77.7%), whereas only 39 (22.3%) were due to the onset of an AE. Primary/secondary failure was the most frequent reason for swaps (124, 79%), while AEs onset led to 33 (21%) swaps. Conclusions: This study supports the validity of our program in monitoring and detecting AEs in the rheumatological area, confirming the positive beneficial/risk ratio of biologics.

Systematic review and meta-analysis of the incidence rates of adverse events after digestive endoscopy in children

BACKGROUND

With the widespread use of digestive endoscopy in children, a variety of adverse events (AEs) have occurred after digestive endoscopy. However, there are notable differences in the incidence of adverse reactions in digestive endoscopy in children at present, which makes it difficult to assess the safety of digestive endoscopy in children.

METHODS

Studies related to digestive endoscopy in children were screened from January 2005 to October 2021 from PubMed, Web of Science, Spring, CNKI, and Science Direct databases. RevMan5.3 and Stata were employed to carry out meta-analysis on the incidence of adverse respiratory events, myoclonus, abdominal pain, fever, bleeding, chest pain, sore throat, vomiting, and delayed capsule discharge after digestive endoscopy in children. The article quality was evaluated by the Agency for Healthcare Research and Quality (AHRQ). The chi-square test and I² were adopted to test literature heterogeneity, and the article publication bias was assessed by displaying an inverted funnel plot as a funnel plot.

RESULTS

In all, 15 articles were included, involving a total of 27,770 children. In all, 15 articles were included, involving a total of 27,770 children. The risk ratio (RR) value of adverse respiratory events after digestive endoscopy in children was 1.31 [95% confidence interval (CI): 1.17 to 1.47, P<0.00001]; the odds ratio (OR) value of the incidence of myoclonus was 1.21 (95% CI: 1.01 to 1.46, P=0.04); the incidence of abdominal pain was 1.18 (95% CI: 1.11 to 1.27, P<0.00001); the incidence of fever was 1.09 (95% CI: 1.06 to 1.12, P<0.00001); the incidence of bleeding was 1.24 (95% CI: 0.94 to 1.64, P=0.13); the incidence of chest pain was 1.06 (95% CI: 1.03 to 1.09, P<0.0001); incidence of sore throat was 1.11 (95% CI: 1.05 to 1.18, P=0.0004); incidence of vomiting was 1.13 (95% CI: 1.06 to 1.21, P=0.0001); and the incidence of delayed capsule expulsion was 1.18 (95% CI: 1.00 to 1.40, P=0.05).

DISCUSSION

The incidence of AEs after digestive endoscopy in children was low, which can be used in the diagnosis and therapy of digestive system diseases in children.

Preventable Adverse Events in Obstetrics-Systemic Assessment of Their Incidence and Linked Risk Factors

(1) Background: Adverse events (AEs) are an inherent part of all medical care. Obstetrics is special: it is characterized by a very high expectation regarding safety and has rare cases of harm, but extremely high individual consequences of harm. However, there is no standardized identification, documentation, or uniform terminology for the preventability of AEs in obstetrics. In this study, therefore, an obstetrics-specific matrix on the preventable factors of AEs is established based on existing literature to enable standardized reactive risk management in obstetrics. (2) Methods: AEs in obstetrics from one hospital from the year 2018 were retrospectively evaluated according to a criteria matrix regarding preventability. Risk factors for preventable AEs (pAEs) were identified. (3) Results: Out of 2865 births, adverse events were identified in 659 cases (23%). After detailed case analysis, 88 cases (13%) showed at least 1 pAE. A total of 19 risk factors could be identified in 6 categories of pAEs. (4) Conclusion: Preventable categories of error could be identified. Relevant obstetric risk factors related to the error categories were identified and categorized. If these can be modified in the future with targeted measures of proactive risk management, pAEs in obstetrics could also be reduced.

Adverse events of rituximab in neuromyelitis optica spectrum disorder: a systematic review and meta-analysis

Background:

The adverse events (AEs) of rituximab (RTX) for neuromyelitis optica spectrum disorder (NMOSD) are incompletely understood.

Aim:

To collate information on the reported the AEs of RTX in NMOSD and assess the quality of evidence.

Methods:

PubMed, EMBASE, Web of Science, Cochrane Library, Wanfang Data, CBM, CNKI, VIP, clinicaltrials.gov, and so on were searched for studies with control groups as well as for case series that had assessed the RTX-associated AEs. The incidence of AEs and the comparison of AE risks among different therapies were pooled. The GRADE was developed for evidence quality.

Results:

A total of 3566 records were identified. Finally, 36 studies (4 RCTs, 6 crochet studies, 2 NRCTs, and 24 case series), including 1542 patients (1299 females and 139 males), were included for final analyses. Rates of patients with any AEs, any serious AEs (SAEs), infusion-related AEs, any infection, respiratory infection, urinary infection, and death were 28.57%, 5.66%, 27.01%, 17.36%, 4.76%, 4.76%, and 0.17%, respectively. The results from subgroup analysis showed that AE rates were most likely not associated with covariates such as duration of illness and study designs. Very low-quality evidence suggested that the risk ratios (RR) of any AEs (0.84, 95% CI = 00.42–1.69, p = 0.62) and any infections (1.24 95% CI = 0.18–8.61) of RTX were similar to that of azathioprine, and the RR of any AEs of RXT was akin to that of mycophenolate mofetil (0.66, 95% CI = 0.32–1.35 p = 0.26). Evidence of low to high quality showed the lower RR of RTX in other AEs, but not in infusion-related AEs. Strategies to handle AEs focused on symptomatic treatments.

Conclusions:

RTX is mostly safer than other immunosuppressants in NMOSD: the incidence of RTX-associated AEs was not high, and when present, the AEs were usually mild or moderate and could be well controlled. Given its efficacy and safety, RTX could be recommended as a first-line treatment for NMOSD.

Real-world hematological adverse events in Chinese patients with advanced ovarian cancer treated with an individualized starting dose of niraparib

Background

This work set out to examine the hematological adverse events (AEs) of an individualized starting dose (ISD) of niraparib in Chinese patients with ovarian cancer (OC).

Methods

The medical records of 43 patients with OC who were treated with an ISD of niraparib at the Cancer Hospital of The University of Chinese Academy of Sciences between February 2019 and January 2020 were retrospectively reviewed. Treatment-emergent hematological AEs were analyzed.

Results

Of the 43 patients with OC, 28 (65.1%) had hematological AEs of ≥ grade 1, including thrombocytopenia (39.5%), leukopenia (37.2%), and anemia (34.9%). Ten (23.3%) patients developed grade 3/4 hematological AEs, including thrombocytopenia (11.6%), leukopenia (9.3%), and anemia (7.0%). Among the individuals who developed AEs during treatment, 9 (32.1%) patients had their treatment interrupted, with treatment being restarted in 8 (28.6%) cases, and 4 (14.3%) patients had the drug dose decreased. No deaths were reported. The median times to the occurrence of any-grade leukopenia, anemia, and thrombocytopenia were 30 (range, 7 to 162), 34 (range, 7 to 108), and 20 (range, 13 to 180) days, respectively. Most AEs occurred within the first 3 months of treatment (93.8% leukopenia, 80.0% anemia, and 76.5% thrombocytopenia). Treatments for AEs included supplementation of recombinant human granulocyte colony-stimulating factor (n=5, 17.9%), erythrocytes (n=2, 7.1%), and recombinant human thrombopoietin (n=5, 17.9%).

Conclusions

The incidence of adverse hematological reactions to an ISD of niraparib in Chinese patients with advanced OC is relatively lower in the real world than in the phase III clinical trials PRIMA (also an ISD) and NOVA. These hematological AEs can be managed through dose adjustment and symptomatic therapy.

An analytical study of drug utilization, disease progression, and adverse events among 165 COVID-19 patients

Background

The coronavirus disease 2019 (COVID-19) epidemic has lasted for nearly 4 months by this study was conducted. We aimed to describe drug utilization, disease progression, and adverse drug events of COVID-19.

Methods

A retrospective, single-center case series study enrolled 165 consecutive hospitalized COVID-19 patients who were followed up until March 25, 2020, from a designated hospital in Wuhan. Patients were grouped by a baseline degree of severity: non-severe and severe. An analytical study of drug utilization, disease progression, and adverse events (AEs) of COVID-19 was conducted.

Results

Of the 165 COVID-19 cases, antivirals, antibacterials, glucocorticoids, and traditional Chinese medicine (TCM) were administered to 92.7%, 98.8%, 68.5%, and 55.2% of patients, respectively. The total kinds of drugs administered to the severe subgroup [26, interquartile range (IQR) 18–39] were 11 more than the non-severe subgroup (15, IQR 10–24), regardless of comorbidities. The 2 most common combinations of medications in the 165 cases were ‘antiviral therapy + glucocorticoids + TCM’ (81, 49.1%) and ‘antiviral therapy + glucocorticoids’ (23, 13.9%). Compared with non-severe cases, severe cases received more glucocorticoids (88.5% vs. 66.2%, P=0.02), but less TCM (50.0% vs. 63.3%, P=0.20), and suffered a higher percentage of death (34.6% vs. 7.2%, P=0.001). At the end of the follow-up, 130 (78.8%) patients had been discharged, and 24 (14.5%) died. There were 13 patients (7.9%) who had elevated liver enzymes, and 49 patients (29.7%) presented with worsening kidney function during the follow-up.

Conclusions

Of the 165 COVID-19 patients, the fatality rate remained high (14.5%). Drug utilization for COVID-19 was diverse and generally complied with the existing guidelines. Combination regimens containing antiviral drugs might be beneficial to assist COVID-19 recovery. Additionally, liver and kidney AEs should not be ignored.

Target therapy for metastatic alveolar soft part sarcoma: a retrospective study with 47 cases

Background

Alveolar soft part sarcoma (ASPS) is a translocation-associated soft-tissue tumor resistant to conventional cytotoxic agents. This report aims to compare the efficacy of anlotinib versus pazopanib as targeted monotherapy in metastatic ASPS and to determine the impact of drug dosage reduction on disease control.

Methods

Sixteen and 31 patients with metastatic ASPS were respectively treated with anlotinib and pazopanib monotherapy at a single institution. Objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were retrieved and compared between both therapeutic arms. Adverse events (AEs) within each group were recorded. Kaplan-Meier survivorship curves computed the impact of drug dosage reduction on PFS.

Results

The anlotinib group showed an ORR of 31.2%, compared to 35.5% in the pazopanib arm (P=0.772). Median PFS was 23.6 months [95% confidence interval (CI), 16.2-31.0 months] in patients treated with anlotinib, but dropped to 13.7 months (95% CI, 10.8-16.7 months) in those managed with pazopanib (P=0.023). One (6.3%) patient on anlotinib and 11 (35.5%) on pazopanib developed AEs requiring drug dosage reduction (P=0.029), which significantly reduced patients' PFS in the latter setting (10.5 vs. 15.8 months, P=0.012). In patients without dosage reduction, anlotinib showed a bordering advantage than pazopanib on median PFS (24.5 vs. 15.8 months, P=0.112).

Conclusions

Compared to pazopanib, anlotinib yielded longer PFS and lower incidence of AEs in ASPS patients. Drug dosage reduction was more frequently encountered with the former agent and affected the disease control.

Stakeholder perspectives on addressing adverse events from adjuvant cancer therapy: A qualitative study

BACKGROUND

With increasing survival rates, a growing population of patients with cancer have received or will receive adjuvant therapy to prevent cancer recurrences. Patients and caregivers will confront the complexities of balancing the preventative benefits of adjuvant therapy with possible near-term or long-term adverse events (AEs). Adjuvant treatment-related AEs (from minimal to severe) can impact therapeutic adherence, quality of life, emotional and physical health, and survival. However, to the authors' knowledge, limited information is available regarding how stakeholders use or desire to use adjuvant-related AE information to inform the care of patients with cancer.

METHODS

A qualitative, purposeful sampling approach was used to elicit stakeholder feedback via semistructured interviews (24 interviews). Drug development, drug regulatory, clinical, payer, and patient/patient advocacy stakeholders were questioned about the generation, dissemination, and use of adjuvant treatment-related AE information to inform the care of patients with cancer. Transcripts were coded independently by 2 senior health care researchers and reconciled to identify key themes.

RESULTS

All stakeholder groups in the current study identified needed improvements in each of the following 4 areas: 1) improving the accessibility and relevance of AE-related information; 2) better integrating and implementing available information regarding AEs for decisions; 3) connecting contemporary cultural and economic value systems to the generation and use of information regarding adjuvant treatment-related AEs; and 4) addressing a lack of alignment and ownership of stakeholder efforts to improve the use of AE information in the adjuvant setting.

CONCLUSIONS

Despite commonalities in the overall needs identified by the diverse stakeholders in the current study, broad systemic change has been stymied. The current study identified the lack of alignment and the absence of a central "owner" of these diffuse efforts as a previously unrecognized hurdle to realizing the desired systemic improvements. Future initiatives aimed at improving quality of life and outcomes for patients receiving adjuvant therapy through the improved use of AE information must address this challenge through innovative collectives and novel leadership strategies.

Clinical presentation, management and outcomes of sacral metastases: a multicenter, retrospective cohort study

Background

Sacral metastases are rare and literature regarding their management is sparse. This multicenter, prospective, observational study aimed to determine health related-quality of life (HRQOL) and pain in patients treated for sacral metastases with surgery and/or radiation therapy (RT). The secondary objectives were to describe the adverse event (AE) profile and change in neurologic function in this population.

Methods

Twenty-three patients presenting with symptomatic sacral metastases were identified from the Epidemiology, Process and Outcomes of Spine Oncology (EPOSO) dataset, a prospective multicenter study on spinal metastases. Patients requiring surgery and/or RT between August 2013 and February 2017 were prospectively enrolled. HRQOL, assessed by the Spine Oncology Study Group Outcomes Questionnaire (SOSGOQv2.0), the Short Form-36 version 2 (SF-36v2), and the EuroQol-5Dimension (EQ-5D) was documented at baseline, 6 weeks, 3 and 6 months post-treatment. Pain numeric rating scale (NRS), AEs, lower extremities motor score (ASIA), and bowel and bladder function were also recorded.

Results

Eight patients underwent surgery ± RT and 15 patients underwent RT alone. Mean age was 59.3 (SD 11.7) years and 13 patients were female. At 6 months, 3 (37.5%) surgical patients and 2 (13.3%) RT patients were deceased. There was a trend showing that surgical patients had worse baseline HRQOL and pain. Pain NRS, EQ-5D, SOSGOQv2.0, and the mental component of the SF-36v2 showed improvement, irrespective of treatment (P>0.05). Ten AEs occurred in the surgical cohort, dominated by wound complications (n=3). Bowel and bladder function improved at 6 weeks in both groups.

Conclusions

Surgical treatment and RT are both valid treatment options for symptomatic sacral metastases. Improvement in HRQOL can be expected with an acceptable AE rate.

Immune checkpoint blockade for advanced non-small cell lung cancer: challenging clinical scenarios

Immune checkpoint blockade has shown anti-tumour activity and improved survival in advanced non-small cell lung cancer (NSCLC). A number of anti-PD-1/PD-L1 and CTLA-4 monoclonal antibody agents have been evaluated in metastatic non-small cell lung cancer. Nivolumab, pembrolizumab and atezolizumab are currently approved for use in clinical practice due to demonstrated improvement in response rate, overall survival (OS) and quality of life (QoL) over standard chemotherapy. We present a series of cases that highlight the clinical challenges that these novel agents present. A review of rare immune-related adverse events (AEs), optimal treatment duration and patient selection will be presented. This series will also address real-life clinical scenarios such as treatment re-challenge and management of immune-related AEs.

Drug-drug interactions in cancer chemotherapy: an observational study in a tertiary health care centre

BACKGROUND

The objective of this study was to evaluate the occurrence of drug-drug interactions (DDIs) in patients on cancer chemotherapy, with the identification of risk factors for these DDIs.

METHODS

This was a cross-sectional, descriptive study carried out at the Department of Onco-Radiation at Guru Gobind Singh Medical College, Faridkot, Punjab. The DDIs were recorded with the help of a drug interaction/interplay information software.

RESULTS

In total, 354 interactions were identified from 283 patient records. The mean age of the patients in the study was 49.05±14.35 years. According to the mechanism of interaction, 306 (86.44%) drug interactions were classified as pharmacokinetic and 48 (13.56%) as pharmacodynamic in nature.

CONCLUSIONS

Sensitization of the treating oncologist and the establishment of alerts, such as electronic alerts or a novel fully digital computerized technology that gives a warning when a health expert enters a patient's prescription orders into the electronic medical documentation, can be helpful in controlling DDIs.

Incident adverse drug reactions in geriatric inpatients: a multicentred observational study

Background

Adverse drug reactions (ADRs) are common in older adults and frequently have serious clinical and economic consequences. This study was conducted as a feasibility study for a randomized control trial (RCT) that will investigate the efficacy of a software engine to optimize medications and reduce incident (in-hospital) ADRs. This study's objectives were to (i) establish current incident ADR rates across the six sites participating in the forthcoming RCT and (ii) assess whether incident ADRs are predictable.

Methods

This was a multicentre, prospective observational study involving six European hospitals. Adults aged ⩾ 65 years, hospitalized with an acute illness and on pharmacological treatment for three or more conditions were eligible for inclusion. Adverse events (AEs) were captured using a trigger list of 12 common ADRs. An AE was deemed an ADR when its association with an administered drug was adjudicated as being probable/certain, according to the World Health Organization Uppsala Monitoring Centre causality assessment. The proportion of patients experiencing at least one, probable/certain, incident ADR within 14 days of enrolment/discharge was recorded.

Results

A total of 644 patients were recruited, evenly split by sex and overwhelmingly of White ethnicity. Over 80% of admissions were medical. The median number of chronic conditions was five (interquartile range 4-6), with eight or more conditions present in approximately 10%. The mean number of prescribed medications was 9.9 (standard deviation 3.8), which correlated strongly with the number of conditions (r = 0.54, p < 0.0001). A total of 732 AEs were recorded in 382 patients, of which 363 were incident. The majority of events were classified as probably or possibly drug related, with heterogeneity across sites (χ² = 88.567, df = 20, p value < 0.001). Out of 644 patients, 139 (21.6%; 95% confidence interval 18.5-25.0%) experienced an ADR. Serum electrolyte abnormalities were the most common ADR. The ADRROP (ADR Risk in Older People) and GerontoNet ADR risk scales correctly predicted ADR occurrence in 61% and 60% of patients, respectively.

Conclusion

This feasibility study established the rates of incident ADRs across the six study sites. The ADR predictive power of ADRROP and GerontoNet ADR risk scales were limited in this population.

Cognitive Interview-Based Validation of the Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events in Adolescents with Cancer

CONTEXT

The National Cancer Institute created the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) to allow direct input on symptomatic adverse events (AEs) from adult patients in oncology trials.

OBJECTIVES

This study sought to determine the youngest age to complete the PRO-CTCAE, evaluated comprehension of PRO-CTCAE among adolescents, tested new items not currently in PRO-CTCAE, and tested a parent-proxy version.

METHODS

From seven pediatric cancer hospitals, 51 adolescents (13-20 years) receiving cancer treatment participated, along with 40 parent proxies. We evaluated 55 AEs from the PRO-CTCAE library (97 questions) and seven new AEs not in PRO-CTCAE that assess symptom frequency, severity, interference, or presence. Questions were distributed across three forms to reduce burden. Cognitive interviews with retrospective probing were completed in age groups of 13-15 and 16-20 year olds. Proxies were interviewed independently.

RESULTS

In general, the 16-20 year olds and the parent proxies were able to understand and complete the PRO-CTCAE and newly designed AE questions. Five PRO-CTCAE terms (bloating of the abdomen, anxiety, flashing lights in front of your eyes, hot flashes, and bed sores) and the wording of the questions about AE severity were challenging for a few adolescents and proxies. The 13-15 year olds had greater challenges completing the PRO-CTCAE.

CONCLUSION

This study extends use of the adult PRO-CTCAE for adolescents as young as 16 years and proposes new questions for seven new symptomatic AEs and a parent-proxy version of PRO-CTCAE. Additional testing of the new questions and alternative language for more challenging PRO-CTCAE items is recommended in adults.
