Researchers are comparing two types of radiation therapy, proton beam radiation therapy PBT and intensity modulated photon radiotherapy IMRT, to treat patients with stage I to IVA esophageal cancer. The study aims to find out whether PBT improves overall survival and causes fewer serious heart and lung side effects compared to IMRT. Additional goals include examining symptom burden, quality of life, tumor response, cost-effectiveness, hospitalization length, lymphocyte levels, and rates of treatment failures and complications. Participants are randomly assigned to one of two groups. One group receives PBT over 28 treatment sessions, five days a week for 5.5 weeks, combined with chemotherapy chosen by the patient and their doctor. The other group receives IMRT on the same schedule with similar chemotherapy options. After chemoradiation, patients may have surgery to remove the esophagus tumor if they are eligible. Throughout the study, blood samples and imaging scans PETCT or CT are collected. Participants are closely monitored during treatment and followed for up to eight years. Follow-up visits occur every 3 to 6 months for the first three years and annually thereafter. The study measures overall survival, heart and lung side effects, symptom changes, tumor response, hospitalization time, immune cell counts, and quality-adjusted life years. The study also collects biospecimens for future research on treatment complications and assesses economic factors related to each radiation therapy.

Researchers are evaluating how well radiation therapy with or without the chemotherapy drug cisplatin works in treating patients who have stage III-IVA squamous cell carcinoma of the head and neck after surgery. This phase II trial aims to understand if adding cisplatin to radiation therapy improves disease-free survival and to explore the role of p53 mutations as a biomarker for treatment benefit. The study also assesses the safety and side effects of these treatments and looks for other genetic changes that might guide new therapies. Participants are randomly assigned to one of two groups. One group receives intensity-modulated radiation therapy IMRT once daily, five days a week for six weeks. The other group receives the same radiation schedule plus weekly intravenous cisplatin for six weeks. After treatment, participants are followed up every six months for three years and then yearly for seven years to monitor outcomes. During the study, patients will have assessments including surgical tumor tissue analysis for p53 mutation, imaging scans to check for cancer spread, and blood tests to monitor health and organ function. Researchers will track disease recurrence, new tumors, or death for up to 10 years. Side effects will be recorded during treatment. The total study participation includes treatment over six weeks followed by long-term follow-up visits lasting up to 10 years.
