Late Feeding Tube Dependency in Head and Neck Cancer Patients Treated with Definitive Radiation Therapy and Concurrent Systemic Therapy.

ABSTRACT: Objective The study aimed to evaluate the impact of late swallowing dysfunction leading to percutaneous endoscopic gastrostomy (PEG) tube dependence on the overall survival (OS) in a cohort of locally advanced head and neck cancer patients treated and cured with definitive radiotherapy (RT) and concurrent systemic therapy (CST). Materials and methods A total of 62 patients with locally advanced head and neck cancer were included in the analysis based on the following selection criteria: stage III, IVA, or IVB disease, treated with definitive RT and CST, no major head and neck surgery, no evidence of local or distant recurrent disease, and at least one post-RT modified barium swallow study. Patients were classified as PEG dependent or PEG independent at the time of the last follow-up. Estimates of OS were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed to evaluate the impact of various clinical factors on OS. Results The median follow-up was 48 months (range: 7.6-235 months). The five-year OS was 64.3% in the PEG-dependent group and 86.1% in the PEG-independent group (p=0.022). Age over 70 at diagnosis was also associated with poorer OS (p=0.044). On univariate analysis, PEG dependency maintained a significantly worse OS (hazard ratio [HR]: 2.59; 95% confidence interval [CI]: 1.11-5.99, p=0.028). On multivariate analysis, PEG dependency (HR: 4.25; 95% CI: 1.33-13.62; p=0.015), advanced N stage (HR: 4.74; 95% CI: 1.17-19.26, p=0.035), and older age at diagnosis (HR: 4.37; 95% CI: 1.21-15.84; p=0.025) were significantly associated with worse OS. Conclusions Late PEG dependency is associated with poor OS in head and neck cancer patients cured with definitive RT and CST. Interventions designed to help head and neck cancer patients maintain swallowing function may result in improved outcomes.

Project description:Rhabdomyosarcoma (RMS) is rare in adults, with a significantly worse prognosis than its pediatric counterpart. Radiotherapy (RT) plays a significant role in treating head and neck RMS (HNRMS), but the outcomes of conventional RT are limited by the complex anatomy and unfavorable pathology subtypes of the adult H&N RMS. Here, we aim to report the effectiveness and safety of carbon-ion beam RT (CIRT), either alone or in combination with proton radiotherapy (PRT) in the management of adult HNRMS. Fifteen adult patients with HNRMS were enrolled on a prospective registry protocol between 06/2015 and 12/2019. Eight patients presented with parameningeal tumors, and eight had unfavorable pathology subtypes [alveolar =7, not otherwise specified (NOS) =1]. Eleven patients had gross tumors before the start of RT (volume range, 46.1-137.6 cm3). Two patients failed the earlier RT. All except for one patient received multi-drug chemotherapy. The median absolute dose of particle beam RT was 70.0 Gy [relative biological effectiveness (RBE)]. With a median follow-up of 21 months, local or distant recurrence occurred in three and four patients, respectively, and two added patients had both local and distant failure. One patient died of distant metastasis (DM), and another died of an unrelated condition. The 1- and 2-year overall survival (OS), local relapse-free survival (LRFS), distant metastasis-free survival (DMFS), and progression-free survival (PFS) rates were 87.5% and 70.0%, 92.3% and 67.1%, 72.2% and 54.2%, and 65.0% and 24.4%, respectively, for the entire cohort. Both patients who failed earlier RT and received salvage CIRT developed DM but were alive at last follow-up. No acute toxicity of ≥ grade 3 or late toxicity of ≥ grade 2 was observed. CIRT, either used alone or in combination with PRT, is not only feasible and safe but also useful in local disease control for HNRMS. DM is the most important cause of treatment failure; thus, more effective systemic treatment is needed to improve the prognosis of HNRMS further.
