TLDR
Proton beam therapy can be a safe and effective curative reirradiation strategy, with acceptable rates of toxicity and durable disease control.Abstract:
Purpose Reirradiation of head and neck (H&N) cancer is a clinical challenge. Proton radiation therapy (PRT) offers dosimetric advantages for normal tissue sparing and may benefit previously irradiated patients. Here, we report our initial experience with the use of PRT for H&N reirradiation, with focus on clinical outcomes and toxicity. Methods and Materials We retrospectively reviewed the records of patients who received H&N reirradiation with PRT from April 2011 through June 2015. Patients reirradiated with palliative intent or without prior documentation of H&N radiation therapy were excluded. Radiation-related toxicities were recorded according to the Common Terminology Criteria for Adverse Events Version 4.0. Results The conditions of 60 patients were evaluated, with a median follow-up time of 13.6 months. Fifteen patients (25%) received passive scatter proton therapy (PSPT), and 45 (75%) received intensity modulated proton therapy (IMPT). Thirty-five patients (58%) received upfront surgery, and 44 (73%) received concurrent chemotherapy. The 1-year rates of locoregional failure–free survival, overall survival, progression-free survival, and distant metastasis–free survival were 68.4%, 83.8%, 60.1%, and 74.9%, respectively. Eighteen patients (30%) experienced acute grade 3 (G3) toxicity, and 13 (22%) required a feeding tube at the end of PRT. The 1-year rates of late G3 toxicity and feeding tube independence were 16.7% and 2.0%, respectively. Three patients may have died of reirradiation-related effects (1 acute and 2 late). Conclusions Proton beam therapy can be a safe and effective curative reirradiation strategy, with acceptable rates of toxicity and durable disease control.read more

TL;DR: In this paper, the authors provide a comprehensive overview of advances from the past three decades on the pathogenic role of EBV, and the genomic, epigenomic and immune landscape of Nasopharyngeal carcinoma (NPC), which have led to the development of new biomarkers, therapeutic targets and improved treatment approaches for patients with NPC.

TL;DR: It is concluded that combination chemotherapy resulted in improved response rates but was associated with an increased toxicity and no improvement in overall survival.

TL;DR: Preclinical data points heavily toward a strong synergy between radiotherapy and immune treatments, however, several issues concerning dosage, timing, patient selection and toxicity need to be resolved before the abscopal effect can become clinically relevant.

Patterns of failure in patients receiving definitive and postoperative IMRT for head-and-neck cancer.
TL;DR: It is shown that the target definition and coverage for patients treated with IMRT for parotid sparing is adequate and the predominant tumor failure within CTV1 may imply the need to identify patients with radioresistant tumor subvolumes within the CTV.

TL;DR: Full-dose reirradiation combined with chemotherapy was feasible in patients with inoperable HNC, and the incidence and severity of late toxicity was markedly increased in comparison to that observed after the first irradiation.
