Background: Patients with local recurrences or new head and neck primary tumors in previously irradiated tissues have few options for salvage treatment. One option for select patients is to undergo reirradiation with concurrent chemotherapy. The purpose of this study is to report the initial clinical results of the Fox Chase phase I and II prospective reirradiation and chemotherapy studies.
Methods: Between July 1996 and January 2002, 38 patients with locally recurrent unresectable squamous cell carcinoma of the head and neck were treated with concurrent chemotherapy and reirradiation on two prospective trials. All patients had received prior radiation therapy to the head and neck region (median dose, 64.2 Gy). Patients received cisplatin and paclitaxel along with hyperfractionated external beam radiation therapy to the site of recurrence.
Results: The median follow-up was 10 months. The median survival was 12.4 months, with actuarial rates of overall survival of 50% and 35% at 1 and 2 years, respectively. During follow-up, 63% of patients experienced local progression of disease, all in the irradiated field. Actuarial progression-free survival at 1 year was 33%, with a median time to progression of 7.3 months. Acute grade 3 to 4 toxicity included neutropenia, nausea, emesis, and mucositis.
Conclusions: Hyperfractionated split-course reirradiation and concurrent cisplatin and paclitaxel chemotherapy demonstrates durable locoregional control in select patients, although late toxicity may occasionally be significant. Only sites of disease recurrence need to be covered in the reirradiation fields.

Background: Online adaptive radiotherapy (OART) and rapid quality assurance (QA) are essential for effective heavy ion therapy (HIT). However, there is a shortage of deep learning (DL) models and workflows for predicting Monte Carlo (MC) doses in such treatments.
Purpose: This study seeks to address this gap by developing a DL model for independent MC dose (MCDose) prediction, aiming to facilitate OART and rapid QA implementation for HIT.

The zinc finger protein 32 (ZNF32) has been associated with high expression in various cancers, underscoring its significant function in both cancer biology and immune response. To further elucidate the biological role of ZNF32 and identify potential immunotherapy targets in cancer, we conducted an in-depth analysis of ZNF32. We comprehensively investigated the expression of ZNF32 across tumors using diverse databases, including TCGA, CCLE, TIMER2.

The occurrence of diseases characterized by irregular spinal alignment, such as kyphosis, lordosis, scoliosis, and dropped head syndrome (DHS) is increasing, particularly among older adults. DHS is characterized by an excessive forward tilt of the head and neck, causing the head to droop. Although it is believed that muscle activity plays a role in both the onset and treatment of DHS, the underlying mechanisms remain unclear.
