A systematic review of quality of life in head and neck cancer treated with surgery with or without adjuvant treatment

Association between objective measures of oral health and salivary gland irradiation with patient-reported outcomes following head and neck radiation therapy

PURPOSE

To determine whether objective measures of oral health and salivary gland irradiation correlates with subjective measures of eating, drinking, and salivation in patients following head and neck radiation therapy (HNRT).

METHODS

This cross-sectional study included 112 patients following HNRT with a completed patient-reported outcome (PRO) scale. Objective measures at post-HNRT visit included decayed-missing-filled teeth (DMFT) scores, periodontal disease condition, oral hygiene status, dental prosthesis use, and prescribed radiation dose to salivary glands. Data were collected and statistical analysis was performed.

RESULTS

There was no significant association between PRO scales and dental prosthesis use, periodontal disease, and oral hygiene. Although some significant findings were seen with DMFT and prescribed radiation dose to salivary glands, this explained only very small amounts of the variation in eating, drinking, and salivation measures in these patients.

CONCLUSION

PRO measures should be integrated in the routine care of patients with head and neck cancer.

Genetic Risk For Depression and Quality of Life in Patients With Head and Neck Cancer

Importance

Although patients with head and neck cancer (HNC) have been shown to experience high distress, few longitudinal studies include a comprehensive evaluation of biopsychosocial factors affecting quality of life (QoL), including genetic risk for depression.

Objective

To identify factors at the time of cancer diagnosis associated with QoL scores at 3 months after treatment in patients newly diagnosed with a first occurrence of HNC.

Design, Setting, and Participants

This prospective longitudinal study of 1464 participants with a 3-month follow-up, including structured clinical interviews and self-administered measures was carried out at the Department of Otolaryngology Head and Neck Surgery at 2 tertiary care McGill University Affiliated Hospitals, McGill University Health Centre, and Jewish General Hospital. Eligible patients were adults newly diagnosed within 2 weeks with a primary first occurrence of HNC, had a Karnofsky Performance Scale score higher than 60, and an expected survival of more than 6 months. Two hundred and twenty-three patients (72%) consented to participate and completed the baseline questionnaire, and 71% completed the 3-month follow-up measures.

Exposures

An a priori conceptual model including sociodemographics, medical variables, psychosocial risk factors, and a polygenic risk score for depression (PRS-D) was tested.

Main outcomes and measures

The Functional Assessment of Cancer Therapy-Head and Neck measured QoL at baseline and at 3 months.

Results

Participants were mostly men (68.7%), with a mean (range) age of 62.9 (31-92) years, 36.6% having a university degree, 35.6% living alone, and 71.4% diagnosed with advanced HNC with mostly cancers being of the oropharynx (42.2%), oral cavity (17%), and larynx (16.3%). QoL at 3 months after HNC diagnosis was associated with higher PRS-D (B = -4.71; 95% CI, -9.18 to -0.23), and a diagnosis of major depressive disorder within 2 weeks of an HNC diagnosis (B = -32.24; 95% CI, -51.47 to 13.02), lifetime suicidal ideation (B = -22.39; 95% CI, -36.14 to -8.65), living with someone (B = 12.48; 95% CI, 3.43-21.52), having smoked cigarettes in the past 30 days pre-HNC diagnosis (B = -15.50; 95% CI, -26.07 to -4.93), chemotherapy type (B = -11.13; 95% CI, -21.23 to -1.02), and total radiotherapy dose (Gy) (B = -0.008; 95% CI, -0.01 to -0.002).

Conclusions and relevance

This study identified the predictive value of a genetic predisposition to depression on QoL and function immediately after oncologic treatments. These findings highlight the potential importance of genetic profiling pretreatment to identify those most susceptible to experience QoL and functional compromise. Depression is a clear area of public health concern and should be a central focus in the treatment of patients with HNC.

Patterns and Trends in Adjuvant Therapy for Major Salivary Gland Cancer

OBJECTIVE

To investigate adjuvant therapy indications, utilization, and associated survival disparities in major salivary gland cancer (MSGC).

STUDY DESIGN

Retrospective cohort study.

SETTING

The 2006 to 2017 National Cancer Database.

METHODS

Patients with surgically resected MSGC were included (N = 11,398). pT3-4 classification, pN2-3 classification, lymphovascular invasion, pathologic extranodal extension (pENE), and positive surgical margin (PSM) were considered indications for adjuvant radiotherapy (aRT). pENE and PSM were considered possible indications for adjuvant chemotherapy. Multivariable logistic and Cox regression models were implemented.

RESULTS

Among 6694 patients with≥ $\ge $ 1 indication for aRT, 1906 (28.5%) received no further treatment and missed aRT. Age, race, comorbidity status, facility type, and distance to reporting facility were associated with missed aRT (P < .025). Among 4003 patients with ≥1 possible indication for adjuvant chemoradiotherapy (aCRT), 914 (22.8%) received aCRT. Patients with pENE only (38.5%) and both pENE and PSM (44.0%) received aCRT more frequently than those with PSM only (17.0%) (P < .001). Academic facility was associated with aCRT utilization (P < .05). aCRT utilization increased between 2006 and 2017 in both academic (14.8% vs 23.9%) and nonacademic (8.8% vs 13.5%) facilities (P < .05). Among 2691 patients with ≥1 indication for aRT alone, missed aRT portended poorer OS (hazard ratio [HR]: 1.61, 95% confidence interval [CI]: 1.28-2.03, P < .001). Among 4003 patients with ≥1 possible indication for aCRT, aRT alone (HR: 1.02, 95% CI: 0.89-1.18, P = .780) and aCRT were associated with similar OS.

CONCLUSION

Missed aRT in MSGC occurs frequently and portends poorer OS. Further studies clarifying indications for aCRT are required.

Prediction of pathological complete response in locally advanced head and neck squamous cell carcinoma treated with neoadjuvant chemo-immunotherapy using volumetric multisequence MRI histogram analysis

PURPOSE

This study aimed to develop a multisequence MRI-based volumetric histogram metrics model for predicting pathological complete response (pCR) in advanced head and neck squamous cell carcinoma (HNSCC) patients undergoing neoadjuvant chemo-immunotherapy (NCIT) and compare its predictive performance with AJCC staging and RECIST 1.1 criteria.

METHODS

Twenty-four patients with locally advanced HNSCC from a prospective phase II trial were enrolled for analysis. All patients underwent pre- and post-NCIT MRI examinations from which whole-tumor histogram features were extracted, including T1WI, T2WI, enhanced T1WI (T1Gd), diffusion-weighted imaging (DWI) sequences, and their corresponding apparent diffusion coefficient (ADC) maps. The pathological results divided the patients into pathological complete response (pCR) and non-pCR (N-pCR) groups. Delta features were calculated as the percentage change in histogram features from pre- to post-treatment. After data reduction and feature selection, logistic regression was used to build prediction models. ROC analysis was performed to assess the diagnostic performance.

RESULTS

Eleven of 24 patients achieved pCR. Pre_T2_original_firstorder_Minimum, Post_ADC_original_firstorder_MeanAbsoluteDeviation, and Delta_T1Gd_original_firstorder_Skewness were associated with achieving pCR after NCIT. The Combined_Model demonstrated the best predictive performance (AUC 0.95), outperforming AJCC staging (AUC 0.52) and RECIST 1.1 (AUC 0.72). The Pre_Model (AUC 0.83) or Post-Model (AUC 0.83) had a better predictive ability than AJCC staging.

CONCLUSION

Multisequence MRI-based volumetric histogram analysis can non-invasively predict the pCR status of HNSCC patients undergoing NCIT. The use of histogram features extracted from pre- and post-treatment MRI exhibits promising predictive performance and offers a novel quantitative assessment method for evaluating pCR in HNSCC patients receiving NCIT.

Neoadjuvant immunotherapy for head and neck squamous cell carcinoma

The neoadjuvant immunotherapy approach marks a significant shift in the treatment paradigm of potentially curable HNSCC. Here, current therapies, despite being highly individualized and advanced, often fall short in achieving satisfactory long-term survival rates and are frequently associated with substantial morbidity.The primary advantage of this approach lies in its potential to intensify and enhance treatment regimens, offering a distinct modality that complements the existing triad of surgery, radiotherapy, and chemotherapy. Checkpoint inhibitors have been at the forefront of this evolution. Demonstrating moderate yet significant survival benefits in the recurrent-metastatic setting with a relatively better safety profile compared to conventional treatments, these agents hold promise when considered for earlier stages of HNSCC.On the other hand, a significant potential benefit of introducing immunotherapy in the neoadjuvant phase is the possibility of treatment de-escalation. By reducing the tumor burden before surgery, this strategy could lead to less invasive surgical interventions. The prospect of organ-sparing protocols becomes a realistic and highly valued goal in this context. Further, the early application of immunotherapy might catalyze a more effective and durable immune response. The induction of an immune memory may potentially lead to a more effective surveillance of residual disease, decreasing the rates of local, regional, and distant recurrences, thereby enhancing overall and recurrence-free survival.However, neoadjuvant immunotherapy is not without its challenges. One of the primary concerns is the safety and adverse events profile. While data suggest that adverse events are relatively rare and manageable, the long-term safety profile in the neoadjuvant setting, especially in the context of curative intent, remains a subject for ongoing research. Another unsolved issue lies in the accurate assessment of treatment response. The discrepancy between radiographic assessment using RECIST criteria and histological findings has been noted, indicating a gap in current imaging techniques' ability to accurately reflect the true efficacy of immunotherapy. This gap underscores the necessity for improved imaging methodologies and the development of new radiologic and pathologic criteria tailored to evaluate the response to immunotherapy accurately.Treatment combinations and timing represent another layer of complexity. There is a vast array of possibilities in combining immunotherapy agents with conventional chemotherapy, targeted therapy, radiation, and other experimental treatments. Determining the optimal treatment regimen for individual patients becomes an intricate task, especially when comparing small, single-arm, non-randomized trials with varying regimens and outcome measures.Moreover, one needs to consider the importance of pre- and intraoperative decision-making in the context of neoadjuvant immunotherapy. As experience with this treatment paradigm grows, there is potential for more tailored surgical approaches based on the patient's remaining disease post-neoadjuvant treatment. This consideration is particularly relevant in extensive surgeries, where organ-sparing protocols could be evaluated.In practical terms, the multi-modal nature of this treatment strategy introduces complexities, especially outside clinical trial settings. Patients face challenges in navigating the treatment landscape, which involves coordination across multiple medical disciplines, highlighting the necessity for streamlined care pathways at specialized centers to facilitate effective treatment management if the neoadjuvant approach is introduced to the real-world.These potential harms and open questions underscore the critical need for meticulously designed clinical trials and correlational studies to ensure patient safety and efficacy. Only these can ensure that this new treatment approach is introduced in a safe way and fulfils the promise it theoretically holds.

Predictors for Success and Failure in Transoral Robotic Surgery-A Retrospective Study in the North of the Netherlands

Transoral Robotic Surgery (TORS) is utilized for treating various malignancies, such as early-stage oropharyngeal cancer and lymph node metastasis of an unknown primary tumor (CUP), and also benign conditions, like obstructive sleep apnea (OSA) and chronic lingual tonsillitis. However, the success and failure of TORS have not been analyzed to date. In this retrospective observational multicenter cohort study, we evaluated patients treated with TORS using the da Vinci surgical system. Success criteria were defined as identification of the primary tumor for CUP, >2 mm resection margin for malignant conditions, and improvement on respiratory polygraphy and tonsillitis complaints for benign conditions. A total of 220 interventions in 211 patients were included. We identified predictors of success, such as low comorbidity status ACE-27, positive P16 status, and lower age for CUP, and female gender and OSA severity for benign conditions. For other malignancies, no predictors for success were found. Predictors of failure based on postoperative complications included high comorbidity scores (ASA) and anticoagulant use, and for postoperative pain, younger age and female gender were identified. This study provides valuable insights into the outcomes and predictors of success and failure in TORS procedures across various conditions and may also help in patient selection and counseling.

Patient-reported outcome measures for dysphagia in head and neck cancer: A systematic review and appraisal of content validity and internal structure

Dysphagia is a major head and neck cancer (HNC) issue. Dysphagia-related patient-reported outcome measures (PROMs) are critical for patient-centred assessment and intervention tailoring. This systematic review aimed to derive a comprehensive inventory of HNC dysphagia PROMs and appraise their content validity and internal structure. Six electronic databases were searched to February 2023 for studies detailing PROM content validity or internal structure. Eligible PROMs were those developed or validated for HNC, with ≥20% of items related to swallowing. Two independent raters screened citations and full-text articles. Critical appraisal followed COSMIN guidelines. Overall, 114 studies were included, yielding 39 PROMs (17 dysphagia-specific and 22 generic). Of included studies, 33 addressed PROM content validity and 78 internal structure. Of all PROMs, only the SOAL met COSMIN standards for both sufficient content validity and internal structure. Notably, the development of 18 PROMs predated the publication of COSMIN standards. In conclusion, this review identified 39 PROMs addressing dysphagia in HNC, of which only one met COSMIN quality criteria. Given that half of PROMs were developed prior to COSMIN guidelines, future application of current standards is needed to establish their psychometric quality.

Psychosocial consequences of head and neck cancer symptom burden after chemoradiation: a mixed-method study

PURPOSE

Patients with head and neck cancer (HNC) experience significant symptom burden from combination chemotherapy and radiation (chemoradiation) that affects acute and long-term health-related quality of life (HRQOL). However, psychosocial impacts of HNC symptom burden are not well understood. This study examined psychosocial consequences of treatment-related symptom burden from the perspectives of survivors of HNC and HNC healthcare providers.

METHODS

This was a cross-sectional, mixed-method study conducted at an NCI-designated comprehensive cancer center. Participants (N = 33) were survivors of HNC who completed a full course of chemoradiation (n = 20) and HNC healthcare providers (n = 13). Participants completed electronic surveys and semi-structured interviews.

RESULTS

Survivors were M = 61 years old (SD = 9) and predominantly male (75%), White (90%), non-Hispanic (100%), and diagnosed with oropharynx cancer (70%). Providers were mostly female (62%), White (46%) or Asian (31%), and non-Hispanic (85%) and included physicians, registered nurses, an advanced practice nurse practitioner, a registered dietician, and a speech-language pathologist. Three qualitative themes emerged: (1) shock, shame, and self-consciousness, (2) diminished relationship satisfaction, and (3) lack of confidence at work. A subset of survivors (20%) reported clinically low social wellbeing, and more than one-third of survivors (35%) reported clinically significant fatigue, depression, anxiety, and cognitive dysfunction.

CONCLUSION

Survivors of HNC and HNC providers described how treatment-related symptom burden impacts psychosocial identity processes related to body image, patient-caregiver relationships, and professional work. Results can inform the development of supportive interventions to assist survivors and caregivers with navigating the psychosocial challenges of HNC treatment and survivorship.

Pain management for post-treatment survivors of complex cancers: a qualitative study of opioids and cannabis

Aim: We aimed to understand experiences with opioids and cannabis for post-treatment cancer survivors. Patients & methods: We conducted seven focus groups among head and neck and lung cancer survivors, using standard qualitative methodology to explore themes around 1) post-treatment pain and 2) utilization, perceived benefits and perceived harms of cannabis and opioids. Results & conclusion: Survivors (N = 25) experienced addiction fears, stigma and access challenges for both products. Opioids were often perceived as critical for severe pain. Cannabis reduced pain and anxiety for many survivors, suggesting that anxiety screening, as recommended in guidelines, would improve traditional pain assessment. Opioids and cannabis present complex harms and benefits for post-treatment survivors who must balance pain management and minimizing side effects.

Skull Base Reconstruction by Subsite after Sinonasal Malignancy Resection

Reconstruction after the resection of sinonasal malignancies is complex and primarily dependent on the defect size and location. While the reconstructive paradigm for sellar mass resection is well delineated, the challenges associated with reconstruction after sinonasal malignancy resection are less well described. This narrative review will address the goals of reconstruction after both endonasal endoscopic and open sinonasal malignancy resection and reconstructive options specific to these subsites. The goals of reconstruction include repairing cerebrospinal fluid leaks, restoring sinonasal function, providing a nasal airway, and optimizing the patient's quality of life. These goals are often complicated by the anatomic nuances of each involved sinus. In this review, we will discuss the methods of reconstruction specific to each sinonasal subsite and describe the factors that guide choosing the optimal reconstructive technique.

Quality of Life After Head and Neck Cancer Surgery and Free Flap Reconstruction: A Systematic Review

BACKGROUND

Different factors can affect the quality of life of patients treated for head and neck cancer undergoing major surgical intervention. However, it remains unclear which specific factors and what possible interventions could have the greatest influence on quality of life postoperatively for patients undergoing surgical resection with free flap reconstruction. The objective of our systematic review was to identify which factors, at the time of surgical treatment, are associated with a worse postoperative quality of life for patients undergoing surgical resection with free flap reconstruction for head and neck cancer.

METHODS

We performed a systematic review of MEDLINE, Embase, CINAHL, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL), from their inception through November 2021. We included peer reviewed studies that evaluated the impact of specific factors on quality of life for adult patients who underwent surgery with free flap reconstruction for head and neck cancer. Two reviewers independently screened citations for eligibility and extracted data. Risk of bias of each study was evaluated using the New-Castle Ottawa Scale. Vote counting and qualitative review were used to synthesize results. All relevant findings were reported.

RESULTS

We initially identified 1971 articles. We included 22 articles in our systematic review, totaling 1398 patients. There was a high level of variability for factors evaluated throughout studies and many studies presented small sample sizes. However, some factors were associated with worse long-term quality of life, including older age, radiotherapy, higher tumor stage, dysphagia, anxiety as well as depressive symptoms. Very few articles analyzed their data for specific tumor subsites and the impact of psychosocial factors was rarely evaluated throughout studies.

CONCLUSIONS

For patients with head and neck cancer requiring free flap reconstruction, some specific factors may correlate with changes in quality of life. However, these findings are based on very few and mostly underpowered studies. A better understanding of factors affecting quality of life could allow a more personalized and overall better quality of care for patients.

Interventions to improve quality of life in patients with head and neck cancers receiving radiation therapy: a scoping review

BACKGROUND

Quality of life (QOL) is impaired in patients with head and neck cancers (HNC) due to illness and treatment-associated morbidity. Although there is evidence from the studies on interventions' role in improving QOL receiving radiation therapy, these are not systematically synthesised. In this scoping review, we searched and synthesised the evidence on interventions to improve the QOL and its impact among patients with HNCs.

METHODS

This scoping review was conducted using the framework proposed by Arksey and O'Malley, and the extensions suggested by Levac et al. were incorporated. Two reviewers independently searched four electronic databases using key thesaurus and free-text terms, and the data was extracted, tabulated, synthesised and reported as categories.

RESULTS

Seventy-nine papers reported various interventions of diverse nature such as pharmacological, physical, nutritional, complementary and alternative therapies, psychosocial, oral care related, laser and photobiomodulation therapies, rehabilitative, educational, technology-based, surgical, device-related and nurse lead interventions. Most studies reported clinically meaningful impact of interventions on QOL, although the outcome differences were often statistically insignificant. Few studies reported a combination of interventions to address the multidimensional concerns faced by patients with HNCs. None of the studies examined the impact of interventions on QOL among long-term survivors of HNCs.

CONCLUSION

As QOL concerns in patients with HNCs are multifaceted, more extensive studies with complex multi-component interventions and robust research designs are warranted.

Stepped-care to improve mental health outcomes among underserved patients with lung and head and neck cancer

BACKGROUND

The comparative effectiveness study (ClinicalTrials.gov, NCT03016403) assessed the effects of a stepped-care intervention versus usual care on mental health outcomes, including anxiety, depression, coping self-efficacy, emotional distress (anxiety and depression combined), health-related quality of life (HRQoL), and perceived stress among underserved patients (i.e., low-income, uninsured, underinsured) with lung cancer (LC) and head-and-neck cancer (HNC).

METHODS

In a randomized controlled trial, we investigated if 147 patients who received the stepped-care intervention had better mental health outcomes compared to 139 patients who received usual care. Using an intent-to-treat approach, we analyzed outcomes with linear mixed models.

RESULTS

For the primary outcomes estimated mean differences (denoted by "Δ"), depression (Δ = 1.75, 95% CI = 0.52, 2.98, p = 0.01) and coping self-efficacy (Δ = -15.24, 95% CI = -26.12, -4.36, p = 0.01) were better for patients who received the intervention compared to patients who received usual care, but anxiety outcomes were not different. For secondary outcomes, emotional distress (Δ = 1.97, 95% CI: 0.68, 3.54, p =< 0.01) and HRQoL (Δ = -4.16 95% CI: -7.45, -0.87, p = 0.01) were better for patients who received the intervention compared to usual care patients, while perceived stress was not different across groups.

CONCLUSIONS

The stepped-care intervention influenced depression and coping self-efficacy, important outcomes for patients with acute illnesses like LC and HNC. Although differences in emotional distress met the minimally important differences (MID) previously reported, depression and HRQoL were not above the MID threshold. Our study is among a few to report differences in mental health outcomes for underserved LC and HNC patients after receiving a psychological intervention.

Decisional regret, symptom burden, and quality of life following transoral robotic surgery for oropharyngeal cancer

BACKGROUND

Transoral robotic surgery (TORS) has equivalent oncologic control to radiotherapy with potential for improved quality of life (QOL) and lower patient-reported decisional regret.

METHODS

Cross-sectional study between 2016 and 2021 of TORS patients with early-stage oropharyngeal squamous cell carcinoma who completed the Decision Regret Scale (DRS), M. D. Anderson Dysphagia Inventory (MDADI), and University of Washington Quality of Life (UW-QOL). The median time from treatment to questionnaire completion was 1.8 years (IQR 1.4-3.3, range 1.0-5.6).

RESULTS

Of 65 patients, 84.6% expressed no or mild decisional regret. Regret was not associated with clinical parameters or adjuvant treatment but was correlated with MDADI (τavg = -0.23, p < 0.001) and UW-QOL (τavg = -0.27, p < 0.001). Worse MDADI was associated with older age and worse UW-QOL was associated with multi-site operation and shorter time to survey.

CONCLUSIONS

Overall, the TORS cohort expressed very limited decisional regret. DRS scores were unaffected by clinicodemographics or additional adjuvant therapies, but decision regret was correlated with worse QOL and worse swallowing.

Functional and quality-of-life outcomes following salvage surgery for recurrent squamous cell carcinoma of the head and neck: a systematic review and meta-analysis

BACKGROUND

Recurrent head and neck squamous cell carcinomas (HNSCC) are frequently managed with salvage surgery, but the impact these operations have on function and quality-of-life (QoL) is understudied. This review aimed to provide a quantitative and qualitative assessment of the functional and QoL effects of salvage surgical procedures.

METHODS

Systematic review and meta-analysis were conducted of studies reporting QoL and function following salvage HNSCC resections.

RESULTS

The search identified 415 articles and 34 were selected for inclusion. Pooled random effects analysis revealed long-term feeding and tracheostomy tube rates of 18% and 7%. Pooled long-term feeding tube rates in open oral and oropharyngeal, transoral robotic, total and partial laryngectomy surgeries were 41%, 25%, 11% and 4%. Eight studies used validated QoL questionnaires.

CONCLUSIONS

Functional and QoL outcomes from salvage surgery are acceptable, but appear to be worse following open procedures. Prospective studies measuring changes over time are needed to assess these procedures impact on patient well-being.

Long-term patient-reported outcomes after reconstructive surgery for head and neck cancer: A systematic review

Current literature on reconstruction after head and neck cancer (HNC) focusses on short-term patient-reported outcomes (PROs), while there is a need for knowledge on long-term consequences. Embase, Medline, Web of Science, and Cochrane were searched for studies on health-related quality of life (HRQoL) after HNC reconstruction, using validated PROMs in at least 50 patients, and a follow-up of more than 1 year. Thirty studies were included, comprising 2358 patients with a follow-up between one and 10 years. The most used questionnaire was the UW-QoL v4. Reconstructive surgery was generally followed by diminished oral function, worsened by radiotherapy. Patients experienced anxiety and fear of cancer recurrence. However, there was a progressive decrease in pain over time with some flaps having more favorable HRQoL outcomes. Age and bony tumor involvement were not related to postoperative HRQoL. These results may lead to better patient counseling and expectation management of HNC patients.

Adjuvant radiotherapy mitigates impact of perineural invasion on oncologic outcomes in early-stage oral cavity squamous cell carcinoma. A multi-institutional analysis of 557 patients

OBJECTIVES

Understand the prognostic impact of perineural invasion (PNI) in early-stage oral cavity squamous cell carcinoma (OCSCC). Assess the influence of adjuvant radiotherapy on outcomes of patients with PNI-positive early-stage OCSCC.

MATERIALS AND METHODS

Retrospective seven-institution cohort study including patients with pathologic T1-2 N0-1 OCSCC who underwent primary surgery with negative margins. Outcomes included disease-free survival (DFS) and locoregional control (LRC). Cox proportional hazards models were used to evaluate oncologic outcomes. Interaction terms were introduced to assess relationships between PNI and adjuvant radiotherapy.

RESULTS

Among 557 patients (mean (SD) age 61.0 (13.9), 47.2% female, 66.6% pathologic T1, 93.5% pathologic N0), 93 had PNI-positive tumors, among which 87.1% underwent neck dissection and 39.6% received radiotherapy. On multivariable analysis, PNI was associated with lower DFS and LRC. Adjuvant radiotherapy was not associated with improved outcomes on multivariable analysis of the entire cohort. However, among patients with PNI-positive tumors, adjuvant radiotherapy significantly decreased hazard for DFS.

CONCLUSION

Among patients with low-risk, early-stage OCSCC, PNI was associated with worse DFS and LRC. In patients with PNI-positive tumors, adjuvant radiotherapy lowered hazard for DFS on multivariable analysis. These data support using adjuvant radiotherapy for patients with early-stage OCSCC with PNI.

Oral Mucosa in Cancer Patients-Putting the Pieces Together: A Narrative Review and New Perspectives

The oral mucosa is a key player in cancer patients and during cancer treatment. The increasing prevalence of cancer and cancer-therapy-associated side effects are behind the major role that oral mucosa plays in oncological patients. Oral mucositis is a debilitating severe complication caused by the early toxicity of chemo and/or radiotherapy that can restrict treatment outcome possibilities, even challenging a patient's survival. It has been referred to as the most feared cancer treatment complication. Predictive variables as to who will be affected, and to what extent, are still unclear. Additionally, oral mucositis is one of the sources of the increasing economic burden of cancer, not only for patients and their families but also for institutions and governments. All efforts should be implemented in the search for new approaches to minimize the apparently ineluctable outburst of oral mucositis during cancer treatment. New perspectives derived from different approaches to explaining the interrelation between oral mucositis and the oral microbiome or the similarities with genitourinary mucosa may help elucidate the biomolecular pathways and mechanisms behind oral mucosa cancer-therapy-related toxicity, and what is more important is its management in order to minimize treatment side effects and provide enhanced cancer support.

Image-Guided Intraoperative Assessment of Surgical Margins in Oral Cavity Squamous Cell Cancer: A Diagnostic Test Accuracy Review

(1) Background: The assessment of resection margins during surgery of oral cavity squamous cell cancer (OCSCC) dramatically impacts the prognosis of the patient as well as the need for adjuvant treatment in the future. Currently there is an unmet need to improve OCSCC surgical margins which appear to be involved in around 45% cases. Intraoperative imaging techniques, magnetic resonance imaging (MRI) and intraoral ultrasound (ioUS), have emerged as promising tools in guiding surgical resection, although the number of studies available on this subject is still low. The aim of this diagnostic test accuracy (DTA) review is to investigate the accuracy of intraoperative imaging in the assessment of OCSCC margins. (2) Methods: By using the Cochrane-supported platform Review Manager version 5.4, a systematic search was performed on the online databases MEDLINE-EMBASE-CENTRAL using the keywords "oral cavity cancer, squamous cell carcinoma, tongue cancer, surgical margins, magnetic resonance imaging, intraoperative, intra-oral ultrasound". (3) Results: Ten papers were identified for full-text analysis. The negative predictive value (cutoff < 5 mm) for ioUS ranged from 0.55 to 0.91, that of MRI ranged from 0.5 to 0.91; accuracy analysis performed on four selected studies showed a sensitivity ranging from 0.07 to 0.75 and specificity ranging from 0.81 to 1. Image guidance allowed for a mean improvement in free margin resection of 35%. (4) Conclusions: IoUS shows comparable accuracy to that of ex vivo MRI for the assessment of close and involved surgical margins, and should be preferred as the more affordable and reproducible technique. Both techniques showed higher diagnostic yield if applied to early OCSCC (T1-T2 stages), and when histology is favorable.

TRIM21 Expression as a Prognostic Biomarker for Progression-Free Survival in HNSCC

Patients with head and neck squamous cell carcinoma (HNSCC) continue to have a rather poor prognosis. Treatment-related comorbidities have negative impacts on their quality of life. TRIM21 is a cytosolic E3 ubiquitin ligase that was initially described as an autoantigen in autoimmune diseases and later associated with the intracellular antiviral response. Here, we investigated the role of TRIM21 as a biomarker candidate for HNSCC in predicting tumor progression and patient survival. We analyzed TRIM21 expression and its association with clinical-pathological parameters in our HNSCC cohort using immunohistochemistry. Our HNSCC cohort included samples from 419 patients consisting of primary tumors (n = 337), lymph node metastases (n = 156), recurrent tumors (n = 54) and distant metastases (n = 16). We found that cytoplasmic TRIM21 expression was associated with the infiltration of immune cells into primary tumors. In addition, TRIM21 expression was significantly higher in primary tumors than in lymph node metastases, and increased TRIM21 expression was correlated with shorter progression-free survival in HNSCC patients. These results suggest that TRIM21 could be a new biomarker for progression-free survival.

[Posttherapeutic quality of life after treatment of salivary gland cancer]

BACKGROUND

In addition to overall survival and recurrence-free interval, posttherapeutic quality of life has been established as an independent criterion for treatment evaluation. Thereby, both the specific changes in the head and neck region and their objectification represent a particular challenge for the assessment of quality of life. There are different validated questionnaires available.

OBJECTIVE

Based on the literature, an overview of the relevant questionnaire instruments is given and the specific aspects in patients with salivary gland cancer are presented.

MATERIALS AND METHODS

A selective literature search was conducted to collect publications dealing with the assessment of health-related quality of life in head and neck tumor patients. The papers were critically appraised and summarized.

RESULTS

There are some validated questionnaires available to measure quality of life in patients with head and neck tumors as well as a few specific questionnaires for patients after parotidectomy.

CONCLUSION

By assessing quality of life using standardized questionnaire instruments, disease and treatment consequences can be objectified. Thus, the need for supportive measures, e.g., for rehabilitation in facial nerve palsy, can be identified more reliably.

Development and Preliminary Validation of the Questionnaire "Evaluation of the Constitution of Social Circles" in Patients Treated for Cancer of the Upper Aerodigestive Tract

PURPOSE

The constitution of social circles around patients treated for cancer of the upper aerodigestive tract (UADT) has a major influence on factors that affect quality of life (QOL) but is poorly assessed, mainly due to a lack of tools. The objective of this study is to develop a questionnaire that assesses the constitution of social circles in a population treated for UADT cancer and to analyze the construct (structural and clinical validity) and criterion validity.

METHODS

The Evaluation of the Constitution of Social Circles (ECSC) questionnaire was developed in French by a committee of experts. Structural validity was analyzed using inter-item correlations. The scores of a group of patients treated for UADT cancer were compared with those of a group of healthy subjects (clinical validity). For criterion validity, the ECSC scores were compared to those from various questionnaires that assess social functioning (QFS), psychological status (HAD), perceived speech impairment (PHI), and QOL (EORTC QLQ-H&N35) in patients.

RESULTS

Structural validity shows low to moderate inter-item correlations which is consistent with the construction of the questionnaire not assessing underlying concepts. Clinical validity was satisfactory regarding the frequency of contact (p = 0.01), satisfaction with the frequency of contact in the private circle (p = 0.03), and the size of the social circles of family and friends (p ≤ 0.01). Criterion validity was adequate with moderate correlations between the ECSC scores and the QFS sub-scores of interest (rs > 0.56, p < 0.05). Anxiety (HAD) had a low correlation (|rs| = 0.46, p < 0.05) with satisfaction with exchanges and the frequency of contact with family. Satisfaction with exchanges with the private circle was moderately correlated with the EORTC QLQ-H&N35 score (rs = 0.56, p = 0.01) and showed a negative trend on the PHI (rs < -0.39, p ≥ 0.05).

CONCLUSION

While the test-retest reliability is yet to be evaluated and the sample size should be increased, this preliminary study shows that the ECSC is a valid tool for assessing the constitution of social circles in patients treated for UADT cancer. It highlights the links between social circles and their functional impact on communication and QOL.

Unmet needs, quality of life and psychological distress: insights regarding head and neck cancer patients in a rural setting

OBJECTIVE

This study aimed to evaluate the perceived quality of life, unmet needs and psychological distress in patients with head and neck cancer in a rural setting in New Zealand.

METHOD

Patients presenting with head and neck cancer in Northland, New Zealand, were asked to complete questionnaires on quality of life, unmet needs, and anxiety or depression together with a free-text option.

RESULTS

About one quarter of respondents (27 per cent) scored high in the anxiety and depression scale, with corresponding diminished quality of life scores and increased needs. Over half of respondents (54 per cent) found it challenging to travel for treatment. Financial difficulties were encountered more frequently with indigenous patients. Rurality alone does not lead to significant differences in quality of life or needs.

CONCLUSION

After treatment for head and neck cancer, it is important to monitor and manage patients' psychological distress and ease of access to health services to improve quality of life.

Changes in oral function, swallowing function, and quality of life in patients with head and neck cancer: a prospective cohort study

Background

Head and neck cancer (HNC) treatment can cause oral morbidities, such as oral dryness and dysphagia, affecting the patient’s quality of life (QOL). The relationship between oral functions and QOL in patients with early-stage HNC remains poorly studied. This study aimed to evaluate changes in the QOL of patients with early-stage HNC and identify factors that affect the QOL of these patients.

Methods

In this prospective cohort study, 37 patients who underwent early-stage (Stage I/Stage II) HNC treatment were evaluated for their oral function, swallowing function, and the QOL score at baseline (BL) and 12 months after surgical treatment (12 M). The participants were divided into two groups: patients who returned to the BL QOL score at 12 M (RE; n = 26) and those who did not (NR; n = 11).

Results

In total, 29.7% (11/37) patients with early-stage HNC did not return to the BL QOL score at 12 M. There was no significant difference between the RE and NR groups regarding the oral and swallowing function. Moreover, oral and swallowing function of all patients returned to the BL at 12 M. The NR group showed lower QOL scores than the RE group in the global health status, and “sticky saliva” parameters in the questionnaires.

Conclusion

Restoration of the oral function is insufficient to improve the QOL of patients with early-stage HNC. The treatment of these patients should instead consider several factors that affect their QOL.

"It's part of our life now": a qualitative exploration of the social eating experiences of family members of patients living with head and neck cancer

Purpose

Family members (FMs) of patients with head and neck cancer (HNC) report a change in their social eating experience. They miss out on the opportunities and benefits that eating with others provides. However, few studies investigate FM’s social eating experiences, with existing research primarily focusing on the patient experience. Therefore, the aim of this study was to explore the social eating experiences of FMs of patients who have had treatment for HNC.

Methods

A qualitative research design using semi-structured interviews was used to understand FM’s social eating experiences. Key themes were inductively developed from the data using reflexive thematic analysis.

Results

Twelve interviews were conducted with FMs, and three key themes were identified: (1) changes and challenges experienced by FMs due to HNC patients’ social eating difficulties, (2) living with social eating changes is a balancing act, and (3) FMs’ efforts to promote social eating for a patient with HNC. FMs expressed significant changes to their social eating habits within and outside the home, indicating the need for support to meet their own emotional, psychological and social needs.

Conclusion

FMs experience many demands and tensions, having to balance the psychological impact they experience, which are often minimised, whilst attempting to find the best ways to support, protect and encourage their loved ones to adjust and adapt to social eating changes. Therefore, interventions need to support FMs’ challenges and equip them to know how to best support patients living with HNC and themselves.

Nanobubbles loaded with carbon quantum dots for ultrasonic fluorescence dual detection

To increase the efficiency and accuracy of clinical tumor detection, we explored multiple imaging by preparing carbon quantum dot (CQD)-loaded nanobubbles for ultrasonic fluorescence dual detection. In this experiment, we prepared 1,2-dioleoyl3-trimethylammonium-propane chloride (DOTAP) cationic liposomes using the film dispersion method and chose perfluoropentane as the core gas material of the nanobubbles. The nanobubbles were coupled with the negatively charged CQDs through the charge effect to prepare the testing agent for two-way diagnosis with ultrasound contrast and fluorescence detection. The formulation and preparation of the loaded CQD liposome nanobubbles were screened. In vivo experiments showed that nanobubbles can be enriched to the tumor site within 5 min, which enables clearer ultrasound imaging and is conducive to tumor detection. We expect CQD-loaded liposome (Lip-CQD) nanobubbles to become a new ultrasonic contrast agent for clinical applications that can provide a basis for early tumor diagnosis and thus earlier treatment.

Considerations for developing supportive care interventions for survivors of head and neck cancer: A qualitative study

OBJECTIVE

This study aimed to describe considerations for developing supportive care interventions targeted to head and neck cancer (HNC) survivors.

METHODS

One-time semi-structured interviews (N = 33) were conducted with HNC survivors who had recently finished treatment (n = 20) and HNC providers (e.g., physicians, nurses; n = 13). Interviews were transcribed verbatim and coded using inductive applied thematic analysis techniques to identify themes.

RESULTS

HNC survivors (75% male; M = 61 years old) and providers (54% physicians; 62% female) were unanimously supportive of developing HNC-specific supportive care interventions. Participants described potential benefits of offering interventions at various points throughout the HNC treatment and survivorship trajectory rather than at a single critical time. Many participants preferred group-based interventions because of the high value of peer-support. Others described how group interventions may not be appropriate for all HNC survivors due to risks for negative social comparisons and exacerbated anxiety. Participants suggested topics that should be addressed in HNC-specific interventions including education about acute and long-term side effects, symptom management, nutritional support, relationship/social role changes, grief/loss, and fear of recurrence.

CONCLUSIONS

HNC-specific supportive care interventions are critically needed, as survivors experience persistent symptoms and distinct psychosocial concerns that impact quality of life. Findings from this study can inform the development of supportive care interventions targeted to the unique psychosocial concerns of HNC survivors.

Translation and validation of M.D. Anderson Symptom Inventory-Thyroid Cancer module in Chinese thyroid cancer patients: a cross-sectional and methodological study

Aim

To translate and validate the Chinese version of the MDASI-THY among thyroid cancer patients.

Background

The M.D. Anderson Symptom Inventory-Thyroid Cancer module (MDASI-THY) is one of well-validated instruments for thyroid-specific symptom assessment. To date, the instrument has not been used in China.

Methods

After standard forward- and back-translation procedures, two instruments, the Chinese version of MDASI-THY and the European Organization for Research and Treatment of Cancer QLQ C30, were answered by 309 thyroid patients. The content, convergent discriminant validity and reliability of the MDASI-THY were evaluated.

Results

The scale of content validity index (S-CVI) and the item of content validity index (I-CVI) of the instrument were over 0.80. There were significant relationships between MDASI-THY and EORTC QLQ-C30 (r range, 0.139 ~ 0.766, -0.759 ~ -0.461, p < 0.001). Symptoms were severer for patients underwent surgical treatment (Z = -9.999, p < 0.001). The Cronbach’s alpha was 0.966 (between 0.954 and 0.827 for subscales). Most symptom items had moderate to high interitem correlations (r range, 0.297 ~ 0.773).

Conclusions

The Chinese version of MDASI-THY demonstrated favorable validity and reliability. It can be used in development of symptom management program in thyroid cancer patients in China.

Relevance to clinical practice

Healthcare providers can apply this instrument to assess Chinese thyroid cancer patients to increase the understanding of their symptom experience, resulting in a better symptom management.

Donor Site Morbidity and Quality of Life after Microvascular Head and Neck Reconstruction with a Chimeric, Thoracodorsal, Perforator-Scapular Flap Based on the Angular Artery (TDAP-Scap-aa Flap)

Extensive defects in the head and neck area often require the use of advanced free flap reconstruction techniques. In this study, the thoracodorsal perforator-scapular free flap technique based on the angular artery (TDAP-Scap-aa flap) was postoperatively evaluated regarding the quality of life and the donor site morbidity using the standardized SF-36 and DASH questionnaires (short form health 36 and disabilities of the arm, shoulder and hand scores). Over a five-year period (2016−2020), 20 selected cases (n = 20) requiring both soft and hard tissue reconstruction were assessed. On average, the harvested microvascular free flaps consisted of 7.8 ± 2.1 cm hard tissue and 86 ± 49.8 cm2 soft tissue components. At the donor site (subscapular region), only a mild morbidity was observed (DASH score: 21.74 ± 7.3 points). When comparing the patients’ postoperative quality of life to the established values of the healthy German norm population, the observed SF-36 values were within the upper third (>66%) of these established norm values in almost all quality-of-life subcategories. The mild donor site morbidity and the observed quality of life indicate only a small postoperative impairment when using the TDAP-Scap-aa free flap for the reconstruction of extensive maxillofacial defects.

Scrambler Therapy Enhances Quality of Life in Cancer Patients in a Palliative Care Setting: A Randomised Controlled Trial

Objectives:

Given the known side effects of opioids and the negative impact of these side effects on quality of life (QOL), there is a need for therapies that can reduce opioid intake and improve QOL in patients suffering from cancer pain. Scrambler therapy (ST) is a neuromodulatory therapy that has been shown to reduce cancer pain, but its effect on QOL is not well understood. This study intended to evaluate the efficacy of ST for enhancing QOL in cancer patients through minimising pain and opioid intake.

Material and Methods:

This was a randomised controlled trial including 80 patients with head, neck and thoracic cancer. In both arms, patients were given pain management drugs following the WHO analgesic ladder for ten consecutive days. In the intervention arm each day ST was given. Pain, morphine intake, and QOL (WHOQOL-BREF) were assessed.

Results:

All domains of QOL improved significantly in the intervention arm in comparison to the control arm. In comparison to baseline, pain improved in both the intervention and the control arm on day 10 and at follow-up. However, QOL significantly improved in the intervention arm, while morphine intake decreased. In the control arm, QOL deteriorated, while morphine intake increased.

Conclusion:

ST significantly improved QOL. Since the increase in QOL took place along with a significantly lower morphine intake, the improvement in QOL may not only be explained by lower pain scores but, also, by a reduced intake of morphine, because the lower dosages of morphine will decrease the likelihood of side effects associated with the drug.

Highly Efficient Separation of Ultratrace Radioactive Copper Using a Flow Electrolysis Cell

Preparing compounds containing the radioisotope ⁶⁴Cu for use in positron emission tomography cancer diagnostics is an ongoing area of research. In this study, a highly efficient separation method to recover ⁶⁴Cu generated by irradiating the target ⁶⁴Ni with a proton beam was developed by employing a flow electrolysis cell (FE). This system consists of (1) applying a reduction potential for the selective adsorption of ⁶⁴Cu from the target solution when dissolved in HCl and (2) recovering the ⁶⁴Cu deposited onto the carbon working electrode by desorbing it from the FE during elution with 10 mmol/L HNO₃, which applies an oxidation potential. The ⁶⁴Cu was selectively eluted at approximately 30 min under a flow rate of 0.5 mL/min from the injection to recovery. The newly developed flow electrolysis system can separate the femtomolar level of ultratrace radioisotopes from the larger amount of target metals as an alternative to conventional column chromatography.

Long-Term Swallowing Outcome and Dysphagia in Advanced Staged Head and Neck Squamous Cell Carcinomas after Radiotherapy

Objective: To evaluate the impact of radiotherapy (RT) on dysphagia and long-term swallowing outcome in patients with stage III and IV head and neck squamous cell carcinomas (HNSCCs). Material and Methods: Between 2005 and 2008, 189 patients with HNSCCs underwent primary or adjuvant RT in a curative setting. Long-term swallowing outcome was evaluated in 50 patients. Among them, 26 were further eligible for prospective analysis of long-term swallowing and dysphagia outcome. Medical charts were retrospectively reviewed regarding pre- and post-treatment dysphagia (3 months after last irradiation setting) as well as persisting long-term dysphagia (2019−2021). Results: Pre-treatment dysphagia was observed in 24 (48%) of 50 patients, particularly in oropharyngeal or hypopharyngeal stage III−IV tumors (OR 9.3; p = 0.003). Conversely, 46 patients (92%) complained about post-treatment dysphagic symptoms, which were more commonly seen in patients with positive neck nodes (OR 10.5; p = 0.037). The post-treatment dysphagia rate dropped from 92% to 24% (p < 0.001) during surveillance, which was significantly linked to xerostomia (OR 5.77; p = 0.019), dysgeusia (OR 9.9; p = 0.036) and free flap reconstruction (OR 6.1; p = 0.022). Conclusion: Pretreatment dysphagia is common in advanced stage HNSCCs and almost all patients complain about dysphagia at the end of RT. Importantly, applied RT protocols did not affect long-term dysphagia, which improves significantly in the majority of patients over time. Meeting Information: Preliminary results have been presented at the 65th Annual Meeting of the Austrian Society of Otorhinolaryngology, 22−26 September 2021, Austria.

Oral cavity squamous cell carcinomas in patients with no identified risk factors: Feeling like an outsider

OBJECTIVES

Head and neck squamous cell carcinomas (HNSCCs) mainly affect smokers and drinkers. However, oral cavity squamous cell cancers (OCSCCs) are increasingly affecting patients with no identified risk factors (NIRFs). This study aimed at characterising their experience of the disease.

METHODS

Qualitative study based on semi-structured interviews of 20 survivors of OCSCC with NIRF. Methods used in grounded theory approach were applied.

RESULTS

Patients with NIRF had a similar experience to that of patients with risk factors regarding treatments. The absence of identified causes led to stigma and led the patients to distance themselves, both from the stereotypic HNSCC cancer patient and the identity as a cancer patient. Furthermore, having no identified risk factors seemed to reinforce the fear of recurrence.

CONCLUSION

This study is the first to address key gaps in knowledge regarding patients with NIRF having survived OCSCC. Their experience is similar to that of patients with orphan diseases. Owing to confrontation with other patients and the repeated questions of caregivers about tobacco/alcohol consumption, these patients felt stigmatised during their treatment. OCSCC patients with NIRF may benefit from guidance and support on how to engage in prevention.

Health-related quality of life in maxillectomy patients undergoing dentoalveolar rehabilitation

OBJECTIVES

Surgical resection of the maxilla impairs aesthetics, speech, swallowing, and mastication. Maxillary reconstruction is increasingly performed with virtual surgical planning (VSP) to enhance functional dental rehabilitation with a conventional denture or osseointegrated implants. The aim of this study was to determine whether dental status and VSP is associated with health-related quality of life (HRQOL) and function in patients who have undergone maxillectomy.

MATERIALS AND METHODS

A cross-sectional study was conducted among patients who underwent free flap reconstruction or obturation of the maxilla between July 2009 and December 2020. The FACE-Q Head and Neck Cancer (FACE-Q) module, M.D. Anderson Dysphagia Inventory (MDADI), and Speech Handicap Index (SHI) were used to evaluate HRQOL.

RESULTS

Forty-three patients (response rate 59%) completed questionnaires and 48% underwent dental rehabilitation. In Okay Class II and III defects, adjusting for the effect of radiotherapy and time from surgery, there was a positive association between denture status and FACE-Q smiling (p = 0.020), eating (p = 0.012), smiling (p = 0.015), and MDADI global (p = 0.015), emotional (p = 0.027), functional (p = 0.028), and composite (p = 0.029) scores. VSP was associated with FACE-Q swallowing (p = 0.005), drooling (p = 0.030), eating (p = 0.008), smiling (p = 0.021), MDADI global (p = 0.017), emotional (p = 0.041), functional (p = 0.040), composite (p = 0.038), and SHI total scores (p = 0.042).

CONCLUSIONS

Dentoalveolar rehabilitation and VSP were associated with higher HRQOL scores relating to eating and drinking, smiling, and speaking.

Experiences and perceptions of social eating for patients living with and beyond head and neck cancer: a qualitative study

Purpose

Patients with head and neck cancer (HNC) describe eating as more than a physical activity for nutrition and calories. After treatment for HNC, patients report a changed social experience around food, with eating and drinking in front of family and friends depicted as a challenge. However, there is limited research exploring how patients with HNC adapt and cope with social eating difficulties. This study aims to explore patients’ experiences and perceptions of social eating and drinking following treatment for HNC.

Methods

A qualitative research design using semi-structured interviews was employed to understand the experiences of social eating of patients living with and beyond HNC. Reflexive thematic analysis was used to inductively develop key themes from the data.

Results

Fourteen interviews were conducted with patients, and two key themes were identified: (1) “Social eating became a conscious process” and (2) “Strategies to maximise social eating participation”. To maximise social eating enjoyment, patients attempted to minimise the attention on their eating function and the fuss created around food. Patients with HNC established psychological and cognitive adaptations to manage expectations and promote positive participation in social eating.

Conclusion

This paper identifies key barriers limiting or diminishing social eating for patients with HNC; including being self-conscious, lack of understanding from others and functional issues with eating and drinking. This research highlights the need to raise awareness of social eating challenges and for the social dimensions of eating to be addressed through family-centred, supportive holistic interventions implemented early in the patient’s cancer journey.

[18F]FDG-PET accurately identifies pathological response early upon neoadjuvant immune checkpoint blockade in head and neck squamous cell carcinoma

Purpose

To investigate the utility of [¹⁸F]FDG-PET as an imaging biomarker for pathological response early upon neoadjuvant immune checkpoint blockade (ICB) in patients with head and neck squamous cell carcinoma (HNSCC) before surgery.

Methods

In the IMCISION trial (NCT03003637), 32 patients with stage II‒IVb HNSCC were treated with neoadjuvant nivolumab with (n = 26) or without (n = 6) ipilimumab (weeks 1 and 3) before surgery (week 5). [¹⁸F]FDG-PET/CT scans were acquired at baseline and shortly before surgery in 21 patients. Images were analysed for SUV_max, SUV_mean, metabolic tumour volume (MTV), and total lesion glycolysis (TLG). Major and partial pathological responses (MPR and PPR, respectively) to immunotherapy were identified based on the residual viable tumour in the resected primary tumour specimen (≤ 10% and 11–50%, respectively). Pathological response in lymph node metastases was assessed separately. Response for the 2 [¹⁸F]FDG-PET-analysable patients who did not undergo surgery was determined clinically and per MR-RECIST v.1.1. A patient with a primary tumour MPR, PPR, or primary tumour MR-RECIST-based response upon immunotherapy was called a responder.

Results

Median ΔSUV_max, ΔSUV_mean, ΔMTV, and ΔTLG decreased in the 8 responders and were significantly lower compared to the 13 non-responders (P = 0.05, P = 0.002, P < 0.001, and P < 0.001). A ΔMTV or ΔTLG of at least − 12.5% detected a primary tumour response with 95% accuracy, compared to 86% for the EORTC criteria. None of the patients with a ΔTLG of − 12.5% or more at the primary tumour site developed a relapse (median FU 23.0 months since surgery). Lymph node metastases with a PPR or MPR (5 metastases in 3 patients) showed a significant decrease in SUV_max (median − 3.1, P = 0.04). However, a SUV_max increase (median + 2.1) was observed in 27 lymph nodes (in 11 patients), while only 13 lymph nodes (48%) contained metastases in the corresponding neck dissection specimen.

Conclusions

Primary tumour response assessment using [¹⁸F]FDG-PET-based ΔMTV and ΔTLG accurately identifies pathological responses early upon neoadjuvant ICB in HNSCC, outperforming the EORTC criteria, although pseudoprogression is seen in neck lymph nodes. [¹⁸F]FDG-PET could, upon validation, select HNSCC patients for response-driven treatment adaptation in future trials.

Selected functional outcomes in advanced oral cancer: Comparison of surgery alone versus surgery with postoperative radiotherapy

BACKGROUND

Study objectives were to determine whether the addition of postoperative radiation (PORT) resulted in a decline in oral function relative to surgery alone and to describe the longitudinal course of oral function following treatment of advanced oral cancer.

METHODS

This was a 36-month retrospectively analyzed observational cohort study of patients with stage III-IV oral cancer. Prospectively collected, oral functional outcomes were acquired pretreatment and 3, 6, 12, 24, and 36 months post-treatment.

RESULTS

One hundred and eighteen patients were included. Forty-three patients treated with surgery alone were compared to 75 who received surgery with PORT. Mixed model analysis demonstrated the acute effect of PORT was associated with patient-rated xerostomia (p < 0.001) and the late or persistent effect was associated with decreased clinician-rated eating in public (p = 0.008), understandability of speech (p = 0.02), and normalcy of diet (p = 0.005) compared with surgery alone. There were no differences between surgery alone and PORT groups in clinician-rated feeding tube dependence or patient-rated speech handicap.

CONCLUSIONS

The use of PORT was associated with a demonstrable decline in oral function in four of six outcomes measures relative to surgery alone.

Neoadjuvant immunotherapy with nivolumab and ipilimumab induces major pathological responses in patients with head and neck squamous cell carcinoma

Surgery for locoregionally advanced head and neck squamous cell carcinoma (HNSCC) results in 30‒50% five-year overall survival. In IMCISION (NCT03003637), a non-randomized phase Ib/IIa trial, 32 HNSCC patients are treated with 2 doses (in weeks 1 and 3) of immune checkpoint blockade (ICB) using nivolumab (NIVO MONO, n = 6, phase Ib arm A) or nivolumab plus a single dose of ipilimumab (COMBO, n = 26, 6 in phase Ib arm B, and 20 in phase IIa) prior to surgery. Primary endpoints are feasibility to resect no later than week 6 (phase Ib) and primary tumor pathological response (phase IIa). Surgery is not delayed or suspended for any patient in phase Ib, meeting the primary endpoint. Grade 3‒4 immune-related adverse events are seen in 2 of 6 (33%) NIVO MONO and 10 of 26 (38%) total COMBO patients. Pathological response, defined as the %-change in primary tumor viable tumor cell percentage from baseline biopsy to on-treatment resection, is evaluable in 17/20 phase IIa patients and 29/32 total trial patients (6/6 NIVO MONO, 23/26 COMBO). We observe a major pathological response (MPR, 90‒100% response) in 35% of patients after COMBO ICB, both in phase IIa (6/17) and in the whole trial (8/23), meeting the phase IIa primary endpoint threshold of 10%. NIVO MONO’s MPR rate is 17% (1/6). None of the MPR patients develop recurrent HSNCC during 24.0 months median postsurgical follow-up. FDG-PET-based total lesion glycolysis identifies MPR patients prior to surgery. A baseline AID/APOBEC-associated mutational profile and an on-treatment decrease in hypoxia RNA signature are observed in MPR patients. Our data indicate that neoadjuvant COMBO ICB is feasible and encouragingly efficacious in HNSCC.

Immune checkpoint blockade has become standard care for patients with recurrent metastatic head and neck squamous cell carcinoma (HNSCC). Here the authors present the results of a non-randomized phase Ib/IIa trial, reporting safety and efficacy of neoadjuvant nivolumab monotherapy and nivolumab plus ipilimumab prior to standard-of-care surgery in patients with HNSCC. .

Optimizing brief, focused assessment of priority symptoms and concerns in recurrent and/or metastatic squamous cell carcinoma of the head and neck: Content validation of the Functional Assessment of Cancer Therapy/National Comprehensive Cancer Network Head and Neck Symptom Index-10 (FHNSI-10)

BACKGROUND AND AIMS

Patients with recurrent and/or metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN) experience vast disease and treatment burdens. Brief, focused instruments are needed to assess patient-reported priority symptoms and concerns as targeted outcome assessments for use in clinical research. Although the instrument was developed based on expert and patient input and is psychometrically valid, the Functional Assessment of Cancer Therapy (FACT)/National Comprehensive Cancer Network (NCCN) Head and Neck Symptom Index-10 (FHNSI-10) has yet to undergo content validation from the perspective of R/M SCCHN patients to evaluate its use as a brief symptom-focused targeted endpoint assessment for use in clinical research.

METHODS

Interviews conducted with R/M SCCHN patients explored priority symptoms and concerns, followed by cognitive debriefing of the FHNSI-10 to evaluate face validity. Transcripts were analyzed, and results were mapped to the FHNSI-10. In accordance with published recommendations, expert input from the original development and published literature was considered for content validity assessment.

RESULTS

A total of 18 patients participated in a concept elicitation interview; saturation was obtained at interview 17. Most (83%) were undergoing active treatment, male (94%), white (72%), and did not have a college degree (67%). The most commonly mentioned symptoms were lumps/swelling, pain, sore throat, difficulty swallowing, and voice changes. For all items, ≥75% reported each question was relevant to their R/M SCCHN experience and 94% reported the instrument captured their experiences with R/M SCCHN.

CONCLUSION

Results provide support for the content validity of the FHNSI-10, inasmuch as all 10 items were spontaneously reported and considered relevant to R/M SCCHN. Content validity might be enhanced by adding cough and hearing impairment items; however, the existing FHNSI-10 covers the majority of symptoms uncovered in interviews with a small sample of R/M SCCHN patients.

Surgical factors associated with patient-reported quality of life outcomes after free flap reconstruction of the oral cavity

OBJECTIVES

To determine which surgical factors are associated with quality-of-life (QOL) outcomes in oral cavity cancer survivors after free flap reconstruction of the oral cavity.

PATIENTS AND METHODS

A cross-sectional study was conducted from a multidisciplinary head and neck cancer (HNC) survivorship clinic. Oral cavity cancer survivors with at least 6-months of postoperative follow-up from ablation and free flap reconstruction were included. Primary outcome measures were validated patient-reported outcome measures (PROMs) including the Eating Assessment Tool-10 (EAT-10) measure of swallowing-specific QOL, University of Washington Quality of Life (UW-QOL) physical and social-emotional subscale scores and feeding tube dependence.

RESULTS

Extent of tongue resection was associated with EAT-10 and the UW-QOL Physical subscale scores. Patients with oral tongue defects reported worse scores than with composite defects in the EAT-10 and UW-QOL physical domain (p = 0.0004, 0.0025, respectively). This association no longer applies when controlling for differences in extent of tongue resection. Patients with anterior composite resections reported worse EAT-10 scores than lateral resections (p = 0.024). This association no longer applies when controlling for extent of tongue resection (p = 0.46). Gastric tube dependence demonstrates similar trends to PROMs.

CONCLUSION

Extent of tongue resection was strongly associated with poor QOL outcomes after free tissue reconstruction of the oral cavity and mediates the associations between other defect characteristics and QOL. These findings demonstrate the need for emphasis on expected oral tongue defects when counseling patients and highlight the need to address QOL in a multidisciplinary fashion post-operatively.

High-Resolution 18F-FDG PET/CT for Assessing Three-Dimensional Intraoperative Margins Status in Malignancies of the Head and Neck, a Proof-of-Concept

The surgical treatment of head and neck malignancies relies on the complete removal of tumoral tissue, while inadequate margins necessitate the use of adjuvant therapy. However, most positive margins are identified postoperatively as deep margins, and intraoperative identification of the deep positive margins could help achieve adequate surgical margins and decrease adjuvant therapies. To improve deep-margin identification, we investigated whether the use of high-resolution preclinical PET and CT could increase certainty about the surgical margins in three dimensions. Patients with a malignancy of the head and neck planned for surgical resection were administered a clinical activity of 4MBq/kg ¹⁸F-FDG approximately one hour prior to surgical initiation. Subsequently, the resected specimen was scanned with a micro-PET-CT imaging device, followed by histopathological assessment. Eight patients were included in the study and intraoperative PET/CT-imaging of 11 tumoral specimens and lymph nodes of three patients was performed. As a result of the increased resolution, differentiation between inflamed and dysplastic tissue versus malignant tissue was complicated in malignancies with increased peritumoral inflammation. The current technique allowed the three-dimensional delineation of ¹⁸F-FDG using submillimetric PET/CT imaging. While further optimization and patient stratification is required, clinical implementation could enable deep margin assessment in head and neck resection specimens.

Prophylactic pentoxifylline and vitamin E use for dental extractions in irradiated patients with head and neck cancer

OBJECTIVE

Osteoradionecrosis (ORN) of the jaw is preceded by dental extractions in up to 10% of cases. We present a case series of post-radiotherapy patients undergoing dental extractions who have received the prophylactic antifibrotic agents pentoxifylline and vitamin E (PVe) to prevent ORN.

STUDY DESIGN

A retrospective review was conducted of 219 patients with head and neck cancer (HNC) undergoing 1079 dental extractions between 2009 and 2020. Data regarding oncological treatment, prophylactic drug regimen, dental history, and clinical outcome was collected.

RESULTS

Twelve patients developed ORN at 17 extraction sites (ORN rates, 1.6% and 5.5% at tooth level and patient level, respectively). PVe regimen compliance significantly decreased ORN rates at the patient level (3.4% vs 11.5%; P < .03) and the tooth level (1.0% vs 3.5%; P < .01) compared with no PVe. Regimen compliance significantly reduced ORN rates in patients with oropharyngeal cancer (P < .01); in those with mandibular (P < .005) molar (P < .003), and flapless extractions (P < .04); in patients with radiation regions >40 Gy (P < .0009); and in those who underwent primary closure (P < .03). Machine learning analysis identified almost all these factors as influential at a tooth level for ORN.

CONCLUSIONS

PVe regimen compliance decreased dental extraction ORN rates more than the literature base rates of 7% at the patient level and 2% at the tooth level. Given its success in managing existing ORN, PVe could be extended prophylactically for dental extractions in irradiated patients with head and neck cancer.

Unmet supportive care needs of patients with rare cancer: A systematic review

OBJECTIVE

Patients with rare cancers may experience different unmet needs than those with common cancer. The objective of this systematic review was to (1) investigate unmet supportive care needs of rare cancer patients throughout the disease trajectory and (2) identify predictive factors for these unmet needs.

METHODS

PubMed, PsycINFO and CINAHL were searched for publications (January 2011 to March 2021) focusing on unmet needs of patients with rare cancer. Two reviewers independently selected studies, extracted data and performed quality assessment. Findings were synthesised.

RESULTS

The search yielded 4,598 articles, of which 59 articles met eligibility criteria and 57 were of medium or high quality. Rare cancer patients most frequently reported unmet needs in the healthcare system and information domain (up to 95%), followed by the psychological domain (up to 93%) and the physical and daily living domain (up to 80%). Unmet needs were mainly reported in the posttreatment phase. The most frequently identified predictors were higher anxiety, younger age and higher neuroticism.

CONCLUSION

Patients with rare cancer have unmet needs throughout their disease trajectory. Supportive care needs of rare cancer patients should be addressed individually, depending on the rare cancer subdomain and phase of disease and from diagnosis onwards.

Combined quality of life and posttraumatic growth evaluation during follow-up care of patients suffering from oral squamous cell carcinoma

Oral cancer therapy is associated with a loss in health-related quality of life (HRQOL) and can also lead to post-traumatic growth (PTG). The current study analyzed the relationship between HRQOL, PTG and influencing clinical factors after treatment. The coherent clinical data of 15 patients were retrospectively analyzed over a 1-year study period. HRQOL and PTG were studied using the University of Washington Quality of Life Version 4 (UW-QOL v4) and Posttraumatic Growth Inventory (PTGI) questionnaires. The results revealed that HRQOL was significantly decreased in a pre- to postoperative manner (P=0.011). Sex demonstrated a nearly significant effect on HRQOL (P=0.058). PTG was experienced the most after surgery, and continuously decreased over the 1-year study period. Patient age had a significant effect on PTG (P=0.040). A significant correlation was also established between HRQOL and PTG (P<0.05). HRQOL and PTG are important influencing factors during postoperative tumor follow-up care and should be simultaneously recorded to address individual patient needs and improve quality of treatment.

The Head and Neck Survivorship Tool (HN-STAR) Trial (WF-1805CD): A protocol for a cluster-randomized, hybrid effectiveness-implementation, pragmatic trial to improve the follow-up care of head and neck cancer survivors

Survivors of head and neck cancer (HNC) can have multiple health concerns. To facilitate their care, we developed and pilot-tested a clinical informatics intervention, HN-STAR. HN-STAR elicits concerns online from HNC survivors prior to a routine oncology clinic visit. HN-STAR then presents tailored evidence-based clinical recommendations as a clinical decision support tool to be used during the visit where the oncology clinician and survivor select symptom management strategies and other actions. This generates a survivorship care plan (SCP). Online elicitation of health concerns occurs 3, 6, and 9 months after the clinic visit, generating an updated SCP each time. HN-STAR encompasses important methods of improving survivorship care (e.g., needs assessment, tailored interventions, dissemination of guidelines) and will be evaluated in a pragmatic trial to maximize external validity. This hybrid type 1 implementation-effectiveness trial tests HN-STAR effectiveness while studying barriers and facilitators to implementation in community oncology practices within the National Cancer Institute Community Oncology Research Program. Effectiveness will be measured as differences in key survivorship outcomes between HNC participants who do and do not use HN-STAR over one year after the clinic visit. The primary endpoint is HNC-specific quality of life; other outcomes include patient-centered measures and receipt of guideline-concordant care. Implementation outcomes will be assessed of survivors, providers, and clinic stakeholders. The hybrid design will provide insight into a dose-response relationship between the extent of implementation fidelity and effectiveness outcomes, as well as how to incorporate HN-STAR into standard practice outside the research setting.

The impact of the COVID-19 pandemic on the quality of life of head and neck cancer survivors

BACKGROUND

Head and neck cancer (HNC) survivors are particularly vulnerable to the deleterious consequences of lockdown and social distancing. The psychosocial effects of the COVID-19 pandemic on this group are still unknown, and we want to explore how their quality of life (QoL) has changed in this unique situation.

MATERIALS AND METHODS

An online survey, composed of pandemic-specific items, plus the EORTC QLQ-C30, was administered to a cohort of HNC survivors. Using previously published reference values as a control group, we have evaluated the impact of the pandemic on their QoL. We have also explored the differences between those who had received a total laryngectomy (LP, laryngectomized population) vs other HNC patients, in order to assess the role of tracheostomy in this regard.

RESULTS

One hundred and twenty-one HNC patients completed the survey. The scores of the physical (80.5 vs 85, p = 0.028), role (78 vs 84, p = 0.030), and emotional functioning (76 vs 81, p = 0.041) were significantly different in the two groups, with worse functioning in our patients. Comparing LP with the other HNC patients, social (76.6 vs 88.9, p = 0.008) and physical functioning (75.5 vs 86.1, p = 0.006) were significantly worse in the former group. LP also reported a greater perception that others are afraid to be close to them (1.67 vs 1.32, p = 0.020). No differences were found between LP with and without voice prosthesis.

CONCLUSIONS

Our results show how HNC patients are at high risk for a worsening in QoL because of the ongoing COVID-19 global pandemic.

A Mechanistic Overview of Taste Bud Maintenance and Impairment in Cancer Therapies

Since the early 20th century, progress in cancer therapies has significantly improved disease prognosis. Nonetheless, cancer treatments are often associated with side effects that can negatively affect patient well-being and disrupt the course of treatment. Among the main side effects, taste impairment is associated with depression, malnutrition, and morbid weight loss. Although relatively common, taste disruption associated with cancer therapies remains poorly understood. Here, we review the current knowledge related to the molecular mechanisms underlying taste maintenance and disruption in the context of cancer therapies.
