Immune Status of Cervical Lymph Nodes in Head and Neck Cancer-A Surgical Oncology Perspective.

Neck dissection for cervical lymph node metastasis is an established procedure for head and neck cancer (HNC). However, with the advent of immunotherapy, head and neck surgical oncologists need to rethink removing all lymph nodes, including those with immune function. We investigated the anti-cancer immune response of the cervical lymph nodes in four patients with human papillomavirus type 16 (HPV16)-positive head and neck squamous cell carcinoma. Using lymphocytes extracted from local, metastatic, and non-metastatic lymph nodes and peripheral blood from these patients, we performed an intracellular flow cytometric cytokine assay using anti-IFNγ and anti-TNF-α monoclonal antibodies to detect HPV16 E6- and E7-specific T cells. HPV status and p16 immunostaining were determined by in situ detection using the HPV RNAscope method and immunohistochemistry. In one case, E6-specific and E7-specific CD8+ T cells were detected in proximal metastatic nodes and distal non-metastatic nodes. This finding suggests that non-metastatic nodes should be preserved for their immune function during neck dissection and that the immune function of non-metastatic lymph nodes is important when administering immunotherapy. In this context, head and neck surgical oncologists treating HNC should consider the place of immunotherapy and neck dissection in the treatment of HNC.

A survey on oral health-related standard of care for head and neck cancer patients in the EU.

To map oral health-related standard of care in the context of head and neck cancer (HNC) treatment across the European Union (EU). Six hundred and ninety centers across the European Union were contacted. The questionnaire contained questions focusing on the team/department structure, HNC treatment planning routines, and assessment and handling of dental treatment needs prior to cancer treatment. Eighty-seven centers across the EU responded. Department structure and number of HNC patients treated per year varied widely and dental professionals are included as part of the team in about 25% of the centers. Standard of care, in terms of dental assessment and preventive dentistry routines, such as recording an orthopantomogram, offering dental treatment, and providing a radiation protection splint and splint for fluoride application, differed significantly among the European regions. Independent of the region, these aspects are positively affected if dental professionals are part of the interdisciplinary treatment team and if dental treatment is offered within the center. Dental professionals are still only to a very limited extent included in interdisciplinary treatment planning teams of HNC patients. However, their inclusion and/or offering dental treatment within the same hospital/center appears to improve oral health-related standard of care. Inclusion of dental professionals in treatment planning teams of HNC patients appears to improve oral health-related standard of care within HNC treatment.

The Diagnostic and Prognostic Value of EBUS-TBNA for Intrathoracic Metastasis in Previously Treated Patients With Head and Neck Cancer.

The present study assessed the diagnostic and prognostic significance of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for suspected intrathoracic metastasis after HNC treatment. A retrospective analysis was conducted on 75 patients with a prior history of head and neck cancer treatment who underwent EBUS-TBNA for suspected intrathoracic metastases between March 2012 and December 2021. A total of 126 targeted lesions, including 107 mediastinal/hilar lymph nodes and 19 intrapulmonary/mediastinal masses, were sampled. The metastatic head and neck cancer (HNC) cases detected by EBUS-TBNA consisted of nasopharyngeal carcinoma (n = 24), oropharyngeal carcinoma (n = 3), hypopharynx carcinoma (n = 6), laryngeal carcinoma (n = 6), and oral cavity carcinoma (n = 6). Cases with negative EBUS-TBNA results consisted of tuberculosis (n = 9), sarcoidosis (n = 3), anthracosis (n = 9), and reactive lymphadenitis (n = 9). Six false-negative cases were found among the 75 patients with suspected intrathoracic metastases. The diagnostic sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of the EBUS-TBNA procedure for metastatic HNC were 88.2, 100.0, 100.0, 80, and 92.0%, respectively. The diagnosis of HNC intrathoracic metastasis by EBUS-TBNA correlated with an adverse prognosis in terms of overall survival (OS) (P = .008). The log-rank univariate analysis and Cox regression multivariate analysis results indicated that the detection of metastatic HNC through EBUS-TBNA was a significant independent prognostic factor for patients with HNC who had received prior treatment. Endobronchial ultrasound-guided transbronchial needle aspiration is a safe, effective, and minimally invasive procedure for assessing suspected intrathoracic metastasis in HNC patients after treatment. The intrathoracic metastasis detected by EBUS-TBNA has crucial prognostic significance in previously treated HNC patients.

Photoactivated HPPH-Liposomal therapy for the treatment of HPV-Negative head and neck cancer

ObjectivesHuman Papillomavirus (HPV)-negative head and neck cancer (HNC) is an aggressive malignancy with a poor prognosis. To improve outcomes, we developed a novel liposomal targeting system embedded with 2-[1-hexyloxyethyl]-2-devinyl pyropheophorbide-a (HPPH), a chlorin-based photosensitizer. Upon exposure to 660 nm light, HPPH phototriggering generates reactive oxygen species. The objective of this study was to evaluate biodistribution and test efficacy of HPPH-liposomal therapy in a patient-derived xenograft (PDX) model of chemoradioresistant HNC. Materials and MethodsPDX models were developed from two surgically resected HNCs (P033 and P038) recurrent after chemoradiation. HPPH-liposomes were created including trace amounts of DiR (Ex/Em 785/830 nm), a near infrared lipid probe. Liposomes were injected via tail vein into PDX models. Biodistribution was assessed at serial timepoints in tumor and end-organs through in vivo DiR fluorescence. To evaluate efficacy, tumors were treated with a cw-diode 660 nm laser (90 mW/cm2, 5 min). This experimental arm was compared to appropriate controls, including HPPH-liposomes without laser or vehicle with laser alone. ResultsHPPH-liposomes delivered via tail vein exhibited selective tumor penetration, with a peak concentration at 4 h. No systemic toxicity was observed. Treatment with combined HPPH-liposomes and laser resulted in improved tumor control relative to either vehicle or laser alone. Histologically, this manifested as both increased cellular necrosis and decreased Ki-67 staining in the tumors treated with combined therapy. ConclusionsThese data demonstrate tumor-specific anti-neoplastic efficacy of HPPH-liposomal treatment for HNC. Importantly, this platform can be leveraged in future studies for targeted delivery of immunotherapies which can be packaged within HPPH-liposomes.

Advances in nanomaterials for the diagnosis and treatment of head and neck cancers: A review.

Nanomaterials (NMs) have increasingly been used for the diagnosis and treatment of head and neck cancers (HNCs) over the past decade. HNCs can easily infiltrate surrounding tissues and form distant metastases, meaning that most patients with HNC are diagnosed at an advanced stage and often have a poor prognosis. Since NMs can be used to deliver various agents, including imaging agents, drugs, genes, vaccines, radiosensitisers, and photosensitisers, they play a crucial role in the development of novel technologies for the diagnosis and treatment of HNCs. Indeed, NMs have been reported to enhance delivery efficiency and improve the prognosis of patients with HNC by allowing targeted delivery, controlled release, responses to stimuli, and the delivery of multiple agents. In this review, we consider recent advances in NMs that could be used to improve the diagnosis, treatment, and prognosis of patients with HNC and the potential for future research.

FREQUENCY OF HUMAN PAPILLOMAVIRUS (HPV) WITH HEAD AND NECK CANCER: A SINGLE ONCOLOGY CENTER EXPERIENCE FROM KARACHI, PAKISTAN

Background: The global incidence of head and neck cancer (HNC) is escalating. This research aimed to analyze the prevalence of human papillomavirus (HPV) in patients suffering from HNC. Material and Methods: We conducted a forward-looking observational study at the Department of Medical Oncology, Jinnah Postgraduate Medical Center, Karachi, Pakistan, from January through September 2021. The study included patients above 15 years old, of any gender, with a confirmed diagnosis of HNC. HPV presence was determined via Polymerase Chain Reaction (PCR) for each patient. Socio-demographic data was collected using a pre-established proforma, and data analysis was executed using SPSS version 23. Results: A total of 305 patients with HCNs were included. The mean age of patients was 46.46±12.58 years. The most common site of HNCs was found to be oral cavity (82%) and squamous cell carcinoma was the most common histological type (94.1%). Of 305 HNCs, 134 had tumor size of T3, 200 had nodal status of N1, 263 had grade II and only had metastasis (2.3%). Out of 305 patients with HNCs, 39 cases were found to be HPV positive. Statistically significant differences were observed between HPV and gender (p=0.048), naswar (p=0.018), betel nut consumption (p=0.020) and site of tumor (p=0.038). Conclusion: The presence of HPV presents distinctive HNC characteristics and may serve as a survival indicator for these types of malignancies. Given the inherent genetic and socio-demographic disparities, along with differences in sexual behaviors and harmful lifestyle habits, the need for sex and race-specific clinical trials for HNC treatment is becoming increasingly evident.

Enhancing Radiotherapy Workflow for Head and Neck Cancer with Artificial Intelligence: A Systematic Review.

Head and neck cancer (HNC) is characterized by complex-shaped tumors and numerous organs at risk (OARs), inducing challenging radiotherapy (RT) planning, optimization, and delivery. In this review, we provided a thorough description of the applications of artificial intelligence (AI) tools in the HNC RT process. The PubMed database was queried, and a total of 168 articles (2016-2022) were screened by a group of experts in radiation oncology. The group selected 62 articles, which were subdivided into three categories, representing the whole RT workflow: (i) target and OAR contouring, (ii) planning, and (iii) delivery. The majority of the selected studies focused on the OARs segmentation process. Overall, the performance of AI models was evaluated using standard metrics, while limited research was found on how the introduction of AI could impact clinical outcomes. Additionally, papers usually lacked information about the confidence level associated with the predictions made by the AI models. AI represents a promising tool to automate the RT workflow for the complex field of HNC treatment. To ensure that the development of AI technologies in RT is effectively aligned with clinical needs, we suggest conducting future studies within interdisciplinary groups, including clinicians and computer scientists.

Chronotherapy in head and neck cancer (HNC): A systematic review.

e18016 Background: Chronotherapy in cancer is optimizing the administration time of anti-cancer treatment according to circadian rhythm and cellular phase to improve the efficacy against tumor cells while decreasing side effects on normal cells. Several randomized controlled trials (RCT) evaluated chronotherapy of chemotherapy (chrono-chemotherapy: time-specific infusions) and/or radiotherapy (chrono-radiotherapy: morning radiotherapy) in various cancers and reported improved treatment efficacy and reduced toxicity. However, the effect of chronotherapy in HNC treatment is unclear as there are no prior systematic reviews reported. Therefore, this systematic review summarizes available clinical evidence on the effect of chrono-chemotherapy (CCT) and chrono-radiotherapy (CRT) on treatment response and adverse events in HNC adult patients. Methods: We conducted a systematic search using Medical Subject Headings (MeSH) in four online databases (OVID, Embase, CINAHL and Scopus), and 6078 articles identified were published in English between the databases' inception date and June 30, 2022. We included original peer-reviewed retrospective and prospective human studies investigating CCT and/or CRT versus conventional treatments in HNC patients. We excluded articles that contained no abstract, were unrelated to HNC, were pre-clinical and case reports, or did not include time-specific interventions in their methods. Results: 16 studies were finally included. Overall, studies were heterogenous in demographics, study design, intervention, and outcome measures, thus meta-analysis could not be performed. Nine studies (RCT = 3, Non-RCT = 2 & Retro = 4) investigated CRT. Squamous cell carcinoma (SCC) was mainly reported as the primary tumor (stage I-II). 7/9 studies reported a significant reduction in the incidence of oral mucositis (Grade ≥3) in the CRT group as opposed to conventional radiotherapy (RT) groups (p < 0.05). In contrast, treatment response was investigated in 4/9 studies and was insignificant (p > 0.05). Seven studies (RCT = 5 & Retro = 2) investigated CCT in patients diagnosed with SSC (stage II-IV). All included studies had concurrent RT. Different chemotherapeutic agents were used in combinations or as a single agent, namely Cisplatin, 5- Fu, Paclitaxel and Docetaxel. CCT groups in all studies achieved a significant reduction in Nausea & Vomiting (Grade ≥3), while a significant reduction in Leukopenia & Thrombocytopenia (Grade ≥3) was reported in 2 studies only (p < 0.05). Treatment response (OS and PFS) was not significantly different (p > 0.05) between both groups except 2 studies reported significantly higher ORR in chronotherapy groups (p < 0.05). Conclusions: CCT and CRT in HNC treatment in most studies provided evidence of toxicity reduction while treatment response was maintained. However, large multicentric randomized controlled studies with standardized protocols and optimized designs are still needed.

A retrospective chart review of palliative care consultation during curative-intent chemoradiation for head and neck cancer.

e24165 Background: Head and neck cancer (HNC) treatment with chemoradiation therapy (CRT) is highly morbid. Patients develop significant symptoms including severe pain, dysphagia, and malnutrition resulting in poor quality of life (QOL), frequent hospitalizations, and high rates of depression. Although integration of palliative care (PC) teams into the care of incurable cancers has resulted in improved QOL, less is known about its integration into the care of patients receiving curative-intent treatments. We sought to characterize the use of PC during HNC CRT at a single cancer center. Methods: We performed a retrospective chart review of patients who received curative-intent CRT for HNC from 1/2008 to 1/2019 at Fox Chase Cancer Center. We excluded patients with metastatic disease or who participated in a PC intervention study. Data extracted included: demographics, comorbidities, cancer subtypes, human papilloma virus (HPV) status, inpatient admissions, feeding tube use, pain medication usage, and PC referrals throughout CRT. We used parametric and non-parametric statistics for hypothesis testing. Results: A total of 332 patients were included; median age was 60, 73% were male, 57.8% had oropharynx HNC, 10.2% had a history of chronic pain, and 18.9% had a psychiatric diagnosis. At the start of treatment, 38.5% of patients were on opioids for cancer pain or chronic pain, which increased to 90.7% of patients by the end of CRT. Six months after CRT, 30% of patients remained on opioids. 44.7% of patients required a feeding tube and 51.4% were admitted to the hospital. Despite the significant symptomatology, only 64 patients (19.2%) were referred to PC during treatment. The patients referred to PC were more likely to be younger (p=0.002), have an inpatient admission during treatment (p=0.001), a history of a psychiatric disorder (p=0.001) or substance abuse (p=0.003), and less likely to have HPV-related HNC. Conclusions: A large majority of patients receiving CRT for HNC faced significant pain with a high hospitalization rate, yet few had the expertise of PC involved in their care. Those who were referred to PC were more likely to have pre-existing substance use or chronic pain. These data provide strong rationale for the development of standardized, PC-based interventions to help with the symptomatology of HNC treatment to better serve this high needs population.

Prospective study: expression levels of microRNA-7-3p and its target STAT3 in head and neck cancer.

Head and neck cancer (HNC) is the seventh most prevalent type of cancer in the globe, and it encompasses a wide range of tumors that affect the oral, facial and neck region. Despite breakthroughs in treatment strategies, patients survival has not increased substantially in the last few decades. Therefore, there is need for quick and reliable biomarkers and therapeutic targets for the treatment of HNC. Interestingly, microRNAs (miRNAs) are a small non-coding RNAs (ncRNAs) that have a role in the post-transcriptional regulation of gene expression. Thus, the aim of the study is to evaluate the role of miR-7-3p in the HNC and normal tissues. A total of 25 HNC and normal tissues were collected from the Department of Oral and Maxillofacial Surgery, Saveetha Dental College and Hospitals. Bioinformatic tool (TargetScan) was used to predict the target for miR-7-3p. The tissue samples were processed for Hematoxylin and Eosin staining and following that total RNA was extracted and analyzed for expression studies using RT-qPCR. The bioinformatic analysis of the current study have revealed that STAT3 is a direct target for miR-7-3p. The histopathological examination showed damaged epithelial cells and keratin pool formation was observed in HNC tissue. Our results have also revealed that the miR-7-3p levels were significantly reduced and STAT3 levels were significantly higher in the HNC tissues when compared to the normal tissues. MiR-7-3p can be used as a prognostic, diagnostic biomarker and therapeutic target for the treatment of HNC.

A proposed framework for the implementation of head and neck cancer treatment at a new cancer center from a radiation oncology perspective.

Establishing a new head and neck cancer (HNC) treatment center requires multidisciplinary team management and expertise. To our knowledge, there are no clear recommendations or guidelines in the literature for the commencement of HNC radiation therapy (RT) at a new cancer center. We propose a novel framework outlining the necessary components required to set-up a new radiation therapy HNC treatment. We reviewed the infrastructure and methodology in the commencement of HNC radiation therapy in our cancer care center and invited several external, experienced metropolitan head and neck radiation oncologists to develop a novel consensus guideline that may be used by new RT centers to treat HNC. Recommendations were presented to our internal and external staff specialists using a survey questionnaire with ratings utilized to determine consensus using pre-defined thresholds as per the American Society of Clinical Oncology Guidelines Methodology Manual. This consensus recommendation aims to improve RT utilization whilst advocating for optimal patient outcomes by presenting a framework for new radiation therapy centers ready to step up and manage the treatment of head and neck cancer patients. We propose these evidence-based consensus guidelines endorsed by external HNC radiation oncologists.

EffEx-HN trial: study protocol for a randomized controlled trial on the EFFectiveness and feasibility of a comprehensive supervised EXercise program during radiotherapy in Head and Neck cancer patients on health-related quality of life

BackgroundWith over 500,000 annually reported cases worldwide, head and neck cancer (HNC) is the seventh most common type of cancer worldwide. Treatment of HNC with chemoradiotherapy frequently results in serious impairments in physical and psychosocial functioning. Besides, HNC patients typically start their cancer treatment already with poor physical and psychosocial health. It has been shown that a sufficient level of physical activity (PA) before, during, and after cancer treatment is associated with fewer negative treatment-related side effects and a better quality of life (QOL). In order to prevent worsening of functioning and limit the physical impact of the HNC treatment, a comprehensive supervised exercise program (CSEP) may be beneficial during early cancer treatment. However, up to now, the feasibility and effectiveness of such a program are not yet investigated thoroughly in HNC. Therefore, the primary objective of this study is to examine the effectiveness of a CSEP during HNC treatment, in addition to usual supportive care, compared to usual supportive care alone, on health-related QOL up to 1 year post-diagnosis. Secondary objectives entail gathering information on (1) the effectiveness of a CSEP on secondary outcomes such as physical and mental function, activities of daily life, and participation in society and (2) the feasibility, possible barriers, and facilitators for participation in a CSEP during HNC treatment.MethodsTo investigate the effectiveness of the CSEP, a parallel, open-label randomized controlled trial will be performed. To study the feasibility of the CSEP, a mixed-method study will be performed in a subgroup of participants. HNC patients are eligible if they receive radiotherapy at the Radiation-Oncology department of the University Hospital of Leuven. A 4-size permuted block randomization will be used. The control group receives the current standard of supportive care. The intervention group receives a CSEP, additional to the same usual supportive care. The CSEP consists of a 12-week intensive phase with 3 exercise sessions of 1 h per week, where supervision is gradually reduced after 6 weeks. During the maintenance phase (from week 13), patients exercise at home with monthly tele-consultations with a physiotherapist. The CSEP contains supervised aerobic and resistance training. In both groups, outcomes of interest are evaluated through self-reported questionnaires and clinical assessments, at baseline, 6 weeks, 12 weeks, 6 months, and 12 months post-diagnosis. The primary endpoint is health-related QOL, measured with the EORTC QLQ-C30 at 6 months post-diagnosis.DiscussionThe study will be conducted in accordance with the Declaration of Helsinki. This protocol has been approved by the ethical committee of the University Hospitals Leuven (s65549). Recruitment started in January 2022. Results will be disseminated via peer-reviewed scientific journals and presentations at congresses.Trial registrationTrial Registration: ClinicalTrials.govIdentifier: NCT05256238Date of registration: February 25, 2022

Abstract 546: Targeting BRAF mutations in head and neck cancer

Abstract The mitogen-activating protein kinase (MAPK) pathway [RAS/RAF/MEK/MAPK] is a well-known mitogenic pathway essential for regulation of cell proliferation, survival, differentiation, invasion, and apoptosis, etc. In normal cells, upon the binding of external stimuli, activated Ras relays the signals through a RAF-MEK-ERK (MAPKKK-MAPKK-MAPK) phosphorylation cascade, leading to MAPK pathway activation. On the other hand, in cancer cells, aberrations or mutations of the pathway components usually could lead to constitutive activation of the pathway, resulting in dysregulation of these cellular processes. Notably, mutations of MAPK pathway components are found in 18% of head and neck cancer (HNC). Among these, mutations of the serine/threonine-protein kinase B-Raf (BRAF gene) account for about 1.8% of HNC (based on TCGA-HNSCC cohort, USA). Serving as one of the key kinase members of the MAPK pathway, BRAF is considered as a precision drug target in various cancer types, including melanoma, thyroid cancer, and non-small cell lung cancer (NSCLC). While the significance of BRAF mutations remains underexplored in HNC, exceptionally favorable responses to BRAF and MEK inhibition had been reported in HNC patients carrying BRAF-mutations. Based on this, we hypothesize that BRAF mutations may confer drug sensitivity and serve as a predictive biomarker for personalized therapy in HNC. Here, we demonstrated that ectopic overexpression of mutated BRAF resulted in MAPK pathway activation in HNC cell models. We also showed that ectopic BRAFV600E could promote the in vitro growth of head and neck cancer cells in both 2D and 3D culture conditions as well as enhance anoikis resistance, which is a prerequisite for metastasis. Further preliminary results showed that the mutated BRAFV600E mutant could promote the invasiveness of HNC cells. In summary, our findings support that targeting the BRAF mutants could be a potential therapeutic approach or precision treatment for HNC.

Predictive Factors for Cancer Treatment Delay in a Racially Diverse and Socioeconomically Disadvantaged Urban Population.

Incremental delays in time to treatment initiation (TTI) have been shown to cause a proportional, increased independent risk of disease-specific mortality for breast cancer, colorectal cancer (CRC), head and neck cancer (HNC), non-small-cell lung cancer (NSCLC), and pancreatic cancer. Studies suggest that delays are associated with racial and socioeconomic disparities. We evaluated associations between patient factors and TTI to identify those associated with delay. This is a retrospective cohort study at an urban community-based academic center of patients diagnosed with or referred for curative-intent treatment of breast cancer, CRC, HNC, NSCLC, and pancreatic cancer from January 2019 to December 2021. Variables of interest included Charlson Comorbidity Index (CCI) score, insurance type, language preference, and inpatient admission 30 days before diagnosis. Factors associated with TTI delay, defined as TTI ≥ 30 days, were assessed using multivariable logistic regression. Among 2,543 patients (69% female), the mean age was 63.4 years and the median TTI was 25 days (IQR, 6-44). Within multivariable models, patients treated as outpatient and not admitted 30 days before diagnosis experienced statistically significant greater delay for CRC (odds ratio [OR], 2.82; 95% CI, 1.71 to 4.66) and NSCLC (OR, 2.11; 95% CI, 1.31 to 3.39). Higher CCI score was associated with delay for HNC (OR, 2.63; 95% CI, 1.04 to 6.66) and NSCLC (OR, 1.75; 95% CI, 1.14 to 2.71). For breast cancer, uninsured and Spanish-speaking patients (OR, 1.79; 95% CI, 1.21 to 2.67) experienced increased TTI. Care coordination/compliance (eg, inpatient 30 days before diagnosis), clinical (eg, medical comorbidities), and socioeconomic (eg, uninsured status) predictors for delayed TTI were identified and may inform delay minimizing interventions. Our data support evidence that TTI delays are associated with demographic and socioeconomic disparities. Existing disparities are likely exacerbated by delays that disproportionately affect patients with care coordination/compliance issues, multiple comorbidities, and lower socioeconomic status.

Interventions to reduce times to diagnosis and treatment of head and neck cancer: A systematic review and narrative synthesis.

We systematically reviewed evidence of health system interventions to reduce diagnostic and treatment intervals for people with head and neck cancer (HNC). Electronic databases were searched from inception to 30 April 2020 for controlled or uncontrolled comparative studies. Primary outcome was any time interval between first clinical presentation and treatment onset. Thirty-seven studies were included. Four types of interventions were identified: single clinic-based (N=4), multidisciplinary clinic-based (N=15), hospital or service re-design (N=12), and health system re-design (N=6). There was some evidence that multidisciplinary interventions improve timeliness of diagnosis and treatment; however, evidence of long-term effectiveness was lacking. Study quality was assessed as either low or moderate. Interventions to reduce times to diagnosis and treatment of HNC are heterogeneous, with limited evidence of effectiveness. Future interventions should account for the complex and dynamic nature of health systems and adhere to best-practice principles for early-diagnosis research.

Management of Older Patients with Head and Neck Cancer: A Comprehensive Review.

The projected increase in life expectancy over the next few decades is expected to result in a rise in age-related diseases, including cancer. Head and neck cancer (HNC) is a worldwide health problem with high rates of morbidity and mortality. In this report, we have critically reviewed the literature reporting the management of older patients with HNC. Older adults are more prone to complications and toxicities secondary to HNC treatment, especially those patients who are frail or have comorbidities. Thus, this population should be screened prior to treatment for such predispositions to maximize medical management of comorbidities. Chronologic age itself is not a reason for choosing less intensive treatment for older HNC patients. Whenever possible, also older patients should be treated according to the best standard of care, as nonstandard approaches may result in increased treatment failure rates and mortality. The treatment plan is best established by a multidisciplinary tumor board with shared decision-making with patients and family. Treatment modifications should be considered for those patients who have severe comorbidities, evidence of frailty (low performance status), or low performance status or those who refuse the recommendations of the tumor board.

Loss to Follow-up in Head and Neck Cancer: A Systematic Review of Randomized Controlled Trials.

To evaluate the reporting and rates of loss to follow-up (LTFU) in head and neck cancer (HNC) randomized controlled trials based in the United States. Pubmed/MEDLINE, Cochrane, Scopus databases. A systematic review of titles in Pubmed/MEDLINE, Scopus, and Cochrane Library was performed. Inclusion criteria were US-based randomized controlled trials focused on the diagnosis, treatment, or prevention of HNC. Retrospective analyses and pilot studies were excluded. The mean age, patients randomized, publication details, trial sites, funding, and LTFU data were recorded. Reporting of participants through each stage of the trial was documented. Binary logistic regression was performed to evaluate associations between study characteristics and reporting LTFU. A total of 3255 titles were reviewed. Of these, 128 studies met the inclusion criteria for analysis. A total of 22,016 patients were randomized. The mean age of participants was 58.6 years. Overall, 35 studies (27.3%) reported LTFU, and the mean LTFU rate was 4.37%. With the exception of 2statistical outliers, study characteristics including publication year, number of trial sites, journal discipline, funding source, and intervention type did not predict the odds of reporting LTFU. Compared to 95% of trials reporting participants at eligibility and 100% reporting randomization, only 47% and 57% reported on withdrawal and details of the analysis, respectively. The majority of clinical trials in HNC in the United States do not report LTFU, which inhibits the evaluation of attrition bias that may impact the interpretation of significant findings. Standardized reporting is needed to evaluate the generalizability of trial results to clinical practice.

Muscle Tension Dysphonia: A Sequeale of Chemoradiotherapy in Patients of Head and Neck Cancer.

It's very important to demarcate that voice is the production of sound by the larynx while speech is articulation of the produced sound by tongue movements, soft palate and the lips. Mucositis, dysphagia, change in speech and voice are the common sequelae of Radiotherapy (RT) alone or in combination with chemotherapy (CRT) which is commonly used in the treatment of head and neck cancer (HNC). The aim of this study was to investigate the patient-reported voice impairment among non laryngeal head and neck cancer survivors who were treated with curative RT/CRT with or without surgery. This tertiary institutional assessor blinded study consists of a study cohort of 128 patients who after of completion of treatment for HNC reported to the laryngology clinic for voice complaints and throat discomfort. The assessment included laryngeal endoscopic and stroboscopic imaging, acoustics assessment and VHI (Vocal handicap index). This study cohort consisted of 89.8% males and 11.2% females. There was hyperadduction and strain of ventricular bands in almost all the cases. There was hyperactivity and compression of both true and false cords in 80.5% of the cases. DSI impairment level showed significant association with gender, VHI, GRBAS score and RT/CRT and it did not show significant association with smoking and surgery, while VHI showed significant association with DSI and RT/CRT and it did not show significant association with gender, smoking and surgery. Muscle tension is a very common effect of RT/RCT and dysphonia can be easily associated with it. Future research needs to focus on specific voice treatment regimens in HNC treated with RT/CRT to improve the quality of life of these patients.

Head and Neck Cancer Management

Head and Neck Cancer (HNC) is a broad category of cancer, comprises of cancer that origin into oral cavity, pharynx, larynx, sinuses and salivary gland. Majority of oral cancer cases reported in Pakistan are metastatic to Head and Neck and are with morphology of squamous cell carcinoma. Locally advance, un-resectable tumors are treated with systemic therapies. Commonly prescribe systemic therapies includes chemotherapy and targeted therapy. However, chemotherapy is the most prescribed systemic therapy because of advance presentation of cases with the morphology of Squamous cell carcinoma. Cisplatin and Carboplatin are drug of choice in HNC treatment. Chemotherapy treatment result in many toxicities such as nausea-vomiting, nephrotoxicity, cystitis, diarrhea, mucositis, ototoxicity, myelosuppresion, allergic reaction and others. These side-effects could be overcome through pharmacological and non-pharmacological interventions.
