RESUMEN
Background and Objectives: Despite decades of experience with definitive chemo-radiotherapy (CRT) in cervical oesophageal cancer (CEC), the loco-regional control and survival outcomes are dismal. This review evaluated the outcomes of various treatment strategies being commonly utilized. Materials and methods: A literature review was conducted to identify relevant articles on CEC published from years 2000-2023 addressing the predefined key questions. These questions focussed on the comparative outcomes of various primary treatment approaches (surgery, CRT, or trimodality treatment) and the radiation dose schedules, volumes, and techniques. Results: CRT is the standard approach for treatment for CEC so far. The potential role of surgery and trimodality approach in settings of evolving surgical approaches needs to be validated. The high dose schedules that are preferentially practiced in CEC have not shown any benefit in improving the disease outcomes over the standard dose schedule of 50.4 Gy. The target volume delineation practice of elective nodal irradiation (ENI) does not have a proven benefit over the involved field irradiation (IFI). The limited evidence on radiation techniques suggests that intensity-modulated radiotherapy/volumetric-modulated arc therapy (IMRT/VMAT) techniques can improve toxicity profile over three-dimensional conformal radiotherapy (3DCRT), but no advantage proven in disease outcomes so far. Conclusion: This review will guide clinicians in decision-making for the management of this relatively rare entity and the directions for future research in these areas. Future large-scale multicentre prospective studies are needed for validating and standardizing our current practices and exploring potential options to improve the outcomes.
RESUMEN
PURPOSE: The rising cost of cancer treatment causes out-of-pocket spending among patients or caregivers in lower-middle-income countries, resulting in acute misery and insolvency. This study aimed to assess the financial toxicity associated with cancer treatment and the coping strategies for cancer treatment adopted among the caregivers of patients with cancer in a tertiary cancer care center. MATERIALS AND METHODS: This prospective cross-sectional study was conducted among the primary caregivers of patients with cancer undergoing curative treatment from March to June 2023. The estimated sample size was 403 caregivers. The financial toxicity was assessed using a modified Comprehensive Score for Financial Toxicity-Functional Assessment of Chronic Illness Therapy tool, and coping strategies were explored using a validated questionnaire of 20 questions. Univariate and multivariate analyses investigated the associations and factors influencing financial toxicity. RESULTS: The caregivers recruited in the study were 403; 83.8% were younger than 50 years, and 66.5% were male. The common cancer types included were breast cancer (27.3%), GI cancer (17.9%), head and neck cancer (12.4%), and gynecological cancer (11.6%). The mean financial toxicity score was 22.32 (standard deviation, 9.55), with 64% experiencing moderate to severe financial toxicity. The most common coping strategies used were spending a portion or all of the savings, borrowing money from others, restructuring their spending habits, seeking financial assistance from the cancer center, and resorting to gold loans. CONCLUSION: Screening patients and their primary caregivers using a modified COST tool can help identify families experiencing severe financial toxicity and provide necessary intervention.

BACKGROUND: Women who use or are in treatment for drug use during the perinatal period often have complex needs and presenting comorbidity. Women who use opioids during pregnancy, and their infants, experience poor outcomes. Drug use by women during pregnancy is a public health priority. This scoping review aimed to (1) map clinical guidelines, treatment protocols and good practice guidance across the UK for women who use or are in treatment for drug use during the perinatal period, (2) identify recommended best practice across health and social care for optimising outcomes and reducing inequalities for these women and (3) identify potential gaps within guidance. METHODS: We followed the Joanna Briggs International (JBI) guidance on scoping reviews and PRISMA Scr extension. A registered protocol, containing a clear search strategy, inclusion, and exclusion criteria was adhered to. Reviewers double screened 25%, discussing disagreements. Data were extracted using a predefined template and charted in tables. Recommendations for best practice were organised around agreed categories. RESULTS: Of 968 documents screened, 111 met the inclusion criteria. The documents included UK-wide, national, regional, and organisational policy documents. They varied in the degree they were relevant to women who use or are in treatment for drug use during the perinatal period, the settings to which they applied, and their intended users. Most were created without patient or public involvement and lacked any clear evidence base. Overall, documents recommended an integrated model of care with a lead professional, clear referral pathways and information sharing between agencies. Guidance suggested referrals should be made to specialist midwives, drug, and social care services. A holistic assessment, inclusive of fathers / partners was suggested. Recent documents advocated a trauma-informed care approach. Opioid substitution therapy (OST) was recommended throughout pregnancy where required. Potential gaps were identified around provision of support for women postnatally, especially when their baby is removed from their care. CONCLUSIONS: This synthesis of recommended practice provides key information for practitioners, service providers and policy makers. It also highlights the need for guidelines to be evidence-based, informed by the experiences of women who use or are in treatment for drug use during the perinatal period, and to address the support needs of postnatal women who have their babies removed from their care.

Circulating cell-free DNA (cfDNA) is a promising tool for liquid biopsy-based tests. cfDNA has been reported to help in the diagnosis, quantification of minimal residual disease, prognosis, and identification of mutations conferring resistance in various types of cancers. Cervical cancer is the fourth most common cancer among women worldwide. High-risk human papillomavirus (hr-HPV) infections have been associated with almost all cervical cancers. Lack of HPV vaccines in national vaccination programs and irregular screening strategies in nations with low or moderate levels of human development index have led to cervical cancer becoming the second leading cause of cancer mortality in women. As HPV integration and overexpression of E6/E7 oncoprotein are crucial steps in the development of cancer, HPV cfDNA could potentially be used as a specific biomarker for the detection of cervical cancer. Many studies have used HPV cfDNA and other gene mutations or mRNA expression profiles for diagnosis and disease surveillance in patients with cervical cancer at various stages of disease progression. In this review we present an overview of different studies discussing the utility of cfDNA in cervical cancer and summarize the evidence supporting its potential use in diagnosis and treatment monitoring.
RESUMEN
C1orf74, also known as URCL4, has been reported to have higher expression and be associated with poor prognosis in lung adenocarcinoma patients, and its role in regulation of the EGFR/AKT/mTORC1 pathway has been recently elucidated. In the current study, we used publicly available data and experimental validation of C1orf74 gene expression and its association with prognosis in cervical cancer patients. qRT-PCR was performed using RNA from cervical cancer cell lines and twenty-five cervical cancer patients. Data from TNMplot revealed that mRNA expression of the C1orf74 gene in primary tumor tissues, as well as metastatic tissues from cervical cancer patients, was significantly higher compared to normal cervical tissues. HPV-positive tumors had higher expression of this gene compared to HPV-negative tumors. qPCR analysis also demonstrated higher expression of C1orf74 in HPV-positive cervical cancer cell lines and most cervical cancer patients. The promoter methylation levels of the C1orf74 gene in cervical cancer tissues were lower compared to normal cervical tissues (p < 0.05). Collectively, our study indicates that higher expression of the C1orf74 gene caused by hypomethylation of its promoter is associated with poor overall survival in cervical cancer patients. Thus, C1orf74 is a novel prognostic marker in cervical cancer.

The utilization of stereotactic body radiation therapy for the treatment of liver metastasis has been widely studied and has demonstrated favorable local control outcomes. However, several predictive factors play a crucial role in the efficacy of stereotactic body radiation therapy, such as the number and size (volume) of metastatic liver lesions, the primary tumor site (histology), molecular biomarkers (e.g., KRAS and TP53 mutation), the use of systemic therapy prior to SBRT, the radiation dose, and the use of advanced technology and organ motion management during SBRT. These prognostic factors need to be considered when clinical trials are designed to evaluate the efficacy of SBRT for liver metastases.

PURPOSE: To evaluate clinical outcomes of recurrent gynaecological cancers treated with reirradiation (reRT) using advanced brachytherapy (BT) technique. METHODS AND MATERIALS: Seventy-six women who underwent reRT with BT for gynaecological cancers at our institute between January 2000 and December 2019 were analysed to determine patient, disease and treatment characteristics and clinical outcomes. Descriptive analysis was used for demographics, and the Kaplan Meir method was used for survival analysis. RESULTS: Median age at recurrence was 55 years (Range: 35-73). Forty-three patients had recurrent cervical cancer with intact uterus, and 33 had recurrent vault/vaginal cancers post adjuvant RT. Eight patients received EBRT prior to BT (Range: 30-50Gy). Twenty-two patients (28.9%) received salvage chemotherapy before consideration of brachytherapy. Brachytherapy application was done using MUPIT in 38, Vienna applicator in 20, Syed Neblett in 8, central vaginal cylinder in 3, multicatheter intravaginal applicator in 2, tandem-ovoids in 4 and Houdek applicator in 1 patient. Median cumulative EQD2 for all courses of radiation was 108 Gy (IQR 92-123 Gy). At median follow up of 39 months, local control (LC), progression-free survival (PFS) and Overall survival (OS) at 2-years was 60%, 56.3%, and 72.9 respectively. Patients who had recurrences beyond 2 years had significantly better OS compared to early recurrences. Patients who received BT doses >40 Gy had a higher LC and PFS. Grade 3 to 4 late rectal toxicity was seen in 10 (13%), bladder toxicity in 6 (8%) and vaginal fibrosis in 24 (31%) patients. CONCLUSION: The use of advanced BT approach in reirradiation setting is a feasible and safe option in treatment of post-treatment recurrent cervical, endometrial, and vaginal cancers.

Fiducial markers are utilized for image guided radiotherapy (IGRT) alignment during the delivery of liver stereotactic body radiosurgery (SBRT). There are limited data demonstrating the impact of matching fiducials on the accuracy of liver SBRT. This study quantifies the benefit of fiducial-based alignment and improvements in inter-observer reliability. Nineteen patients with 24 liver lesions were treated with SBRT. Target localization was performed using fiducial markers on cone-beam computed tomography (CBCT). Each CBCT procedure was retrospectively realigned to match both the liver edge and fiducial markers. The shifts were recorded by seven independent observers. Inter-observer variability was analyzed by calculating the mean error and uncertainty for the set-up. The mean absolute Cartesian error observed from fiducial and liver edge-based alignment was 1.5 mm and 5.3 mm, respectively. The mean uncertainty from fiducial and liver edge-based alignment was 1.8 mm and 4.5 mm, respectively. An error of 5 mm or greater was observed 50% of the time when aligning to the liver surface versus 5% of the time when aligning to fiducial markers. Aligning to the liver edge significantly increased the error, resulting in increased shifts when compared to alignment to fiducials. Tumors of 3 cm or farther from the liver dome had higher mean errors when aligned without fiducials (4.8 cm vs. 4.4 cm, p = 0.003). Our data support the use of fiducial markers for safer and more accurate liver SBRT.

Introduction: Perianal tumours are a rare site of malignancy, and tumours primarily involving the perineal body without vaginal and anal canal involvement are uncommon. Case summary: A 67-year-old woman presented with a lesion involving the perineum and rectovaginal septum without extension into vaginal or anorectal mucosa and with skip lesions in the vulva. Biopsy was confirmative of squamous cell carcinoma, with p16 positive. A complete metastatic workup with MRI of the pelvis and CECT thorax and abdomen was done. She was diagnosed with perianal carcinoma stage cT2N0M0 Stage II (American Joint Committee on Cancer 8th Edition of Cancer Staging) since the lesion reached the anal verge. Given the location of the tumour (perineal body), comorbidities and advanced age, she received radical radiotherapy with an intensity-modulated radiotherapy technique - 56 Gy in 28 fractions with the intention of organ preservation. The response assessment with MRI at 3 months showed a complete tumour response. She has been disease-free for 3 years and is on regular follow-ups. Conclusion: Isolated perineal body squamous cell carcinomas are unusual, and synchronous vulvar skip lesion makes this case unique. Radical radiotherapy achieved organ preservation with tumour control and minimal toxicity in an elderly frail patient.
RESUMEN
Both (biological) sex and (socio-cultural) gender are relevant for health but in large-scale studies specific gender measures are lacking. Using a masculine gender-score based on 'traditional masculine-connotated aspects of everyday life', we explored how masculinity may affect sex differences in the prevalence of chronic health problems. We used cross-sectional data (2008-2012) from the Doetinchem Cohort Study to calculate a masculine gender-score (range 0-19) using information on work, informal care, lifestyle and emotions. The sample consisted of 1900 men and 2117 women (age: 40-80). Multivariable logistic regressions including age and SES were used to examine the role of masculine gender on sex differences in the prevalence of diabetes, coronary heart disease, CVA, arthritis, chronic pain and migraine. Men had higher masculine gender-scores than women (12.2 vs 9.1). For both sexes, a higher masculine gender-score was associated with lower prevalence of chronic health problems. Diabetes, CHD, and CVA were more prevalent in men, and gender-adjustment resulted in greater sex differences: e.g. for diabetes the ORsex changed from 1.21 (95 %CI 0.93-1.58) to 1.60 (95 %CI 1.18-2.17). Arthritis, chronic pain, and migraine were more prevalent in women, and gender-adjustment resulted in smaller sex differences: e.g. for chronic pain the ORsex changed from 0.53 (95 %CI 0.45-0.60) to 0.73 (95 %CI 0.63-0.86). Gender measured as 'everyday masculinity' is associated with lower prevalence of chronic health problems in both men and women. Our findings also suggest that the commonly found sex differences in the prevalence of chronic health problems have a large gender component.
RESUMEN
PURPOSE: Breaking bad news (BBN) is a vital part of oncology practice. We conducted this study to assess an abbreviated PENS protocol [Patient preference, Explanation, Next appointment, and Support] for BBN in oncology outpatient (OP) settings. METHODS: This observational study was conducted in a university teaching hospital, including cancer patients who were unaware of their condition and willing to discuss their disease status. The duration of BBN was the primary outcome. After the BBN session, patients filled a validated questionnaire; response scores of ≤ 13 were classified as content with BBN. RESULTS: Fifty patients (mean age 53.7 years, range 28-76) were included in the study. The average duration of BBN was 6.1 (range 2-11) min. Assessed by the response score sum, 43 (86%) patients were satisfied with BBN. Only three (6%) of the discontented patients felt that the BBN duration was too short. Most (94%) of patients reported that they understood the information imparted during the BBN session. After the session, 36 (72%) patients admitted to either feeling the same or reassured compared to before the session. The oncologists also were comfortable with PENS. CONCLUSIONS: The PENS approach is a practical method for BBN, especially when the oncologists have higher OP workloads. More extensive trials are required to validate the protocol in other settings. TRIAL REGISTRATION: Clinical Trial Registry of India (CTRI/2021/07/034707).

Purpose: The primary objective was to compare 3'-deoxy-3'-(18F) fluorothymidine (FLT) positron emission tomography (PET)/computed tomography (CT) uptake in 3 cohorts of stereotactic body radiation therapy (SBRT) patients: (1) pre-SBRT, (2) stable post-SBRT lung fibrosis, and (3) suspicious or proven local recurrence post-SBRT. The secondary objectives were to optimize FLT-PET imaging by comparing FLT uptake in respiratory-gated (4-dimensional) versus nongated (3-dimensional) FLT-PET scans. Methods: Patients with early-stage non-small cell lung cancer planned or treated with SBRT at the institution with radiographic findings of fibrosis or recurrence were eligible for the study. All patients underwent imaging with FLT-PET/CT before SBRT in cohort 1 and at fibrosis or recurrence in cohort 2 and 3, respectively. The planned sample size was 20 patients in each cohort, with 60 patients total. FLT-PET standardized uptake value (SUV) variables including SUVmax, SUVmean, SUVpeak, SUV50, and SUV95 were compared among the 3 cohorts using the Kruskal-Wallis test. The correlation of respiratory-gated and nongated FLT-PET SUV variables was performed using the Spearman correlation coefficient. Results: Forty-one patients were recruited for the study (20 in cohort 1, 16 in cohort 2, and 5 in cohort 3) between 2015 and 2019. The majority received a diagnosis of stage I lung cancer (86%), and the most common prescription was 48 Gy in 4 fractions (59%). Respiratory-gated FLT-PET was performed in 35 patients. The FLT SUV variables were well correlated between respiratory-gated and nongated scans (r = 0.8-1.0). The SUVpeak, SUVmean, and SUVmax were significantly lower in the fibrosis cohort compared with the recurrence and pretreatment cohorts. The SUV50 and SUV95 values in the recurrence cohort were statistically similar to the pretreatment cohort. Conclusions: FLT-PET/CT may be helpful in differentiating SBRT-related fibrosis from recurrence. Nongated FLT-PET/CT with reporting of SUVmax and SUV95 values is recommended.
RESUMEN
Locally advanced esophageal cancer has a dismal prognosis. Surgery remains the cornerstone treatment with 5-year survival rates of approximately 12-39%. Rates of local failure and distant metastases are high following surgical resection of locally advanced tumors. Neoadjuvant therapy (either radiation therapy, chemotherapy, or a combination) prior to surgery carries the advantage of tackling micrometastases and improving complete resection rates. Neoadjuvant concurrent chemotherapy and radiotherapy are a favored approach with evidence for improved pathologic complete response (pCR) rates and improved survival compared with surgery alone. Randomized trials of the optimal neoadjuvant approach are ongoing.

Hepatocellular carcinoma (HCC) accounts for 90% of liver tumours and is one of the leading causes of mortality. Cirrhosis due to viral hepatitis, alcohol or steatohepatitis is the major risk factor, while liver dysfunction due to cirrhosis is a deciding factor in its treatment. The treatment modalities for HCC include liver transplant, hepatectomy, radiofrequency ablation, transarterial chemoembolisation, transarterial radioembolisation, targeted therapy, immunotherapy, and radiation therapy. The role of radiation therapy has been refined with the increasing use of stereotactic body radiation therapy (SBRT). Trials over the past two decades have shown the efficacy and safety of SBRT in recurrent and definitive HCC, leading to its acceptance and adoption in some more recent guidelines. However, high quality level I evidence supporting its use is currently lacking. Smaller randomised trials of external beam radiation therapy suggest high efficacy of radiation therapy compared to other treatments for patients with unresectable HCC, and phase III trials comparing SBRT with other modalities are ongoing. In this review, we discuss the rationale for SBRT in HCC and present evidence on its efficacy, associated toxicity, and technological advances.
RESUMEN
The advent of molecular profiling has revolutionized the treatment of lung cancer by comprehensively delineating the genomic landscape of the epidermal growth factor receptor (EGFR) gene. Drug resistance caused by EGFR mutations and genetic polymorphisms of drug metabolizing enzymes and transporters impedes effective treatment of EGFR mutant and resistant lung cancer. This review appraises current literature, opportunities, and challenges associated with liquid biopsy and pharmacogenomic (PGx) testing as precision therapy tools in the management of EGFR mutant and resistant lung cancers. Liquid biopsy could play a potential role in selection of precise tyrosine kinase inhibitor (TKI) therapies during different phases of lung cancer treatment. This selection will be based on the driver EGFR mutational status, as well as monitoring the development of potential EGFR mutations arising during or after TKIs treatment, since some of these new mutations may be druggable targets for alternative TKIs. Several studies have identified the utility of liquid biopsy in the identification of EGFR driver and acquired resistance with good sensitivities for various blood-based biomarkers. With a plethora of sequencing technologies and platforms available currently, further evaluations using randomized controlled trials (RCTs) in multicentric, multiethnic and larger patient cohorts could enable optimization of liquid-based assays for the detection of EGFR mutations, and support testing of CYP450 enzymes and drug transporter polymorphisms to guide precise dosing of EGFR TKIs.

To report the outcomes of patients with head and neck squamous cell cancers (HNSCC) who received radiotherapy as a part of their first line treatment. All patients treated with radiotherapy for HNSCC between 2013 and 2017 were retrospectively identified from the department records. Patients with follow-up of less than 3 months following primary treatment were excluded. The demographic, disease and outcome details were retrieved from the patients' hospital records. The disease free survival (DFS) was estimated with Kaplan-Meier analysis, and effect of different variables on DFS were compared using log-rank test. The late toxicities of treatment were also recorded and reported. A total of 311 patients were found to be eligible. Most patients were males (82%), and oral cavity cancers predominated (45.3%). 237 patients (76.2%) had locally advanced disease at presentation. Radiotherapy was used as definitive treatment for 152 patients (48.9%). At a median follow up of 14.8 months (range: 3-85.2 months), the estimated Disease-Free Survival (DFS) was 52.7 months (95%CI: 37.7-67.7 months). Locally advanced disease correlated with a significantly lower median DFS (61.2 vs. 32.8 months; p = 0.01), but other factors, including gender, use of concurrent chemotherapy and adjuvant vs definitive radiotherapy appeared to have no statistical association with DFS. 181 (58.2%) patients had chronic RT-related toxicities at last follow-up, but most were generally mild, most frequently subcutaneous fibrosis (48.6%, which occurred significantly more frequently in patients receiving adjuvant RT following surgery- 40.8% versus 57.2%; p = 0.03) and xerostomia (32.4%). Radiation induced osteoradionecrosis was rare, occurring in only three (1%).Most HNSCC patients present with locally advanced disease, where disease control remains poor. Though there is substantial toxicity following treatment, the risk of severe toxicities with modern radiotherapy is low.
RESUMEN
PURPOSE: Intracavitary brachytherapy using High-Dose-Rate (HDR) and Low-dose-rate (LDR) in cervical cancer has been utilized. We report the long-term final results of a large randomized trial in terms of toxicities and efficacy. METHODS AND MATERIALS: Between 1996 to 2005, 816 patients were randomized to LDR (nâ¯=â¯441 patients) or HDR brachytherapy (nâ¯=â¯369 patients) stratified by FIGO Stage grouping. Patients with Stage I-II received external irradiation of 40 Gy in 20 fractions (with midline block (MLB)) followed by either 2 LDR Intracavitary applications of 30 Gy to point A (2-3 weeks apart) or 5 HDR Intracavitary applications of 7 Gy to point A once weekly. Patients with Stage III received 50 Gy in 25 fractions (with MLB after 40 Gy) followed by either one application of LDR 30 Gy to point A or three applications of HDR 7 Gy to point A once weekly. RESULTS: With a median follow-up was 64 months (interquartile range [IQR]: 21 - 111), moderate to severe rectal and bladder complications were higher in LDR arm as compared to HDR arm (9.7% vs. 3.6%; pâ¯=â¯0.02) and (10.5% vs. 5.5%; pâ¯=â¯0.06) for Stage I-II. No difference in rectal or bladder complications for Stage III patients. Disease free and overall survivals were similar in both the arms for all stages. CONCLUSIONS: HDR intracavitary brachytherapy with 7 Gy per fraction weekly is superior to LDR in terms of late rectal and bladder complications. Local control rates and survivals are similar irrespective of stages.

BACKGROUND: Stereotactic body radiotherapy (SBRT) is increasingly being performed for hepatocellular cancer and liver metastases. The purpose of this study was to review the practice of SBRT for hepatocellular, pancreatic cancer and liver metastases in India. METHODS: A survey comprising of 25 questions was designed and served to radiation oncology professionals at two major conferences. The survey consisted of 25 multiple choice questions on SBRT infrastructure and caseload, simulation methods and immobilizations, organ motion control methods, simulation and delivery, indications of liver and pancreatic SBRT and prescribed dose. The responses were analyzed using descriptive statistics. RESULTS: From January to June 2017, about 200 professionals were approached and 71 professionals responded with a response rate of 35.5%. The duration of the SBRT practice among respondents was less than 3 years in 53% with 32% having formal training in SBRT. The most common sites for the use of SBRT were lung and brain followed by liver and spine. Liver SBRT was practiced by 29 (59.2%) for hepatic oligometastases, hepatocellular carcinoma (HCC), and cholangiocarcinoma. The most common fractionation used was 50-60 Gy/6 fractions and 45 Gy/3 fractions. Pancreatic SBRT was practiced by 37%, mostly for medically inoperable or locally advanced pancreatic cancer. SBRT was not practiced by 22 (31%) of the respondents, and the main reasons were lack of infrastructure and structured training. CONCLUSION: The SBRT for liver has increased with a usage rate of over 50% amongst respondents. Pancreatic SBRT use is infrequent and limited to inoperable or advanced cases. Lack of infrastructure and training are the main challenges in the routine adaptation of SBRT.

OBJECTIVE/HYPOTHESIS: To estimate the prevalence of baseline clinically significant distress (distress score ≥ 4) in head and neck cancer patients planned and treated with radical intent radiotherapy using the National Comprehensive Cancer Network Distress Thermometer (DT) and assess factors predictive of distress. STUDY DESIGN: Cross-sectional study. METHODS: This was a cross-sectional study evaluating distress in 600 head and neck cancer patients undergoing radiation therapy. The DT was used to screen patients for distress at baseline before radiotherapy. RESULTS: The median distress score of the entire cohort was 4 interquartile range (IQR) (IQR: 3-5), and 340 patients (56.7%) had clinically significant distress. On univariate analysis, the causal factors predictive of distress were low socioeconomic status (P = .04), presence of proliferative growth at presentation (P = .008), site of the tumor (oral cavity, P = .02), comorbidity (P = .04), and presence of Ryle's tube or tracheostomy tube at baseline (P = .01). Low socioeconomic status was significant (P = .04) on multivariate analysis for high levels of distress. CONCLUSIONS: Among head and neck cancer patients, 56% of patients had clinically significant baseline distress, and patients with low socioeconomic status had high distress. There is a need for interventions to mitigate distress. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:2023-2029, 2021.
