ABSTRACT Compliance to intensive multiweek radiation therapy (RT) regimens in head and neck cancer (HNC) patients is challenging, particularly among medically underserved patients with fewer financial and social resources. Treatment prolongation reduces local control and overall survival rates, making adherence to treatment a key factor in optimal outcome. We evaluated factors affecting compliance in medically underserved patients who received RT for HNC in a large municipal hospital setting in New York City.
Retrospective review.
Treatment records of patients treated between July 2004 and August 2008 were reviewed. Number of and reasons for missed treatments were identified. Several demographic, toxicity, and treatment variables were analyzed for impact on compliance.
Eighty consecutive HNC patients who underwent RT with a 5- to 7-week regimen were identified. Thirty-two patients (40%) missed no treatments, 36 (45%) missed one to six treatments, six (8%) missed seven to 14 treatments, two (3%) missed more than 14 treatments, and four (5%) did not complete treatment. Reasons for missed treatments were hospitalization (31% of events) and toxicity (20%). Patients with percutaneous endoscopic gastrostomy tube were more likely to miss treatments (P = .01, chi(2) test). No other variable showed a significant association with missed treatments (chi(2) test).
Intensive RT for HNC can be delivered with very good adherence within a medically underserved population. Eighty-five percent of patients completed treatment with 0 to 6 days of interruption. Efforts to further improve adherence in this population are ongoing.

    ABSTRACT: Background The aim of this study was to analyse the reasons for not starting or for early of radiotherapy at the Radiation Oncology Department.Methods All radiotherapy treatments from March 2010 to February 2012 were included. Early withdrawals from treatment those that never started recorded. Clinical, demographic and dosimetric variables were also noted.ResultsFrom a total of 3250 patients treated and reviewed, 121 (4%) did not start or complete the planned treatment. Of those, 63 (52%) did not receive any radiotherapy fraction and 58 (48%) did not complete the course, 74% were male and 26% were female. The mean age was 67¿±¿13 years. The most common primary tumour was lung (28%), followed by rectum (16%). The aim of treatment was 62% radical and 38% palliative, 44% of patients had metastases; the most common metastatic site was bone, followed by brain. In 38% of cases (46 patients) radiotherapy was administered concomitantly with chemotherapy (10 cases (22%) were rectal cancers).The most common reason for not beginning or for early withdrawal of treatment was clinical progression (58/121, 48%). Of those, 43% died (52/121), 35 of them because of the progression of the disease and 17 from other causes. Incomplete treatment regimens were due to toxicity (12/121 (10%), of which 10 patients underwent concomitant chemotherapy for rectal cancer).Conclusions The number of patients who did not complete their course of treatment is low, which shows good judgement in indications and patient selection. The most common reason for incomplete treatments was clinical progression. Rectal cancer treated with concomitant chemotherapy was the most frequent reason of the interruption of radiotherapy for toxicity.

    ABSTRACT: A state of the science review to assess how nutritional status and malnutrition are defined by the community of researchers studying head & neck cancer (HNC) patients. In 117 publications, nutritional status was described diversely, ranging from merely one to all six of the following features: weight loss, body composition, quantity/type of food intake, symptoms impacting oral intake, inflammation and altered metabolism. Methods of assessment of each feature were inconsistent. Cancer- and treatment-related symptoms impacting oral intake were a prominent theme. Metabolic changes potentially related to weight loss and efficacy of nutritional therapy were rarely described (<15% of articles). There were 24 different explicit definitions for malnutrition. Consensus is needed regarding the criteria to adequately describe HNC-associated malnutrition. Standardization of assessments will permit aggregation of data, and integration into clinical practice-specifically, development of consensus criteria for implementation and termination of nutrition therapies.

    ABSTRACT: The objective was to analyze the radiotherapy (RT) practice at the cancer centre of a tertiary academic medical institution in Delhi. This audit from an Indian public institution covered patient care processes related to cancer diagnosis, integration of RT with other anti-cancer modalities, waiting time, overall treatment time, and compliance with RT. Over a period of one year, all consecutively registered patients in radiotherapy were analyzed for the audit cycle. Analysis of 1,030 patients showed median age of 49.6 years, with presentation as stage I and II in 14.2%, stage III and IV in 71.2% and unknown stage in 14.6%. A total of 974 (95%) were advised for RT appointment; 669 (68.6%) for curative intent and 31.4% for palliation. Mean times for diagnostic workup and from registration at cancer centre to radiotherapy referral were 33 and 31 days respectively. Median waiting time to start of RT course was 41 days. Overall RT compliance was 75% and overall duration for a curative RT course ranged from 50 days to 61 days. Non-completion and interruption of RT course were observed in 12% and 13% respectively. Radiotherapy machine burden in a public cancer hospital in India increases the waiting time and 25% of advised patients do not comply with the prescribed treatment. Infrastructure, machine and manpower constraints lead to more patients being treated on cobalt (74%) and by two-dimensional (78%) techniques.
