This study proposes to develop and maintain a biorepository of blood samples collected from patients receiving definitive chemoradiotherapy for locally advanced rectal cancer, locally advanced pancreatic cancer, non-small cell lung cancer, or cervical cancer. The ultimate goal of this biorepository will be to provide the resource to initiate an exploration of ctDNA as a potential liquid biopsy for GI and Thoracic malignancy detection and surveillance.

The purpose of this study is to determine if GC4419, administered prior to intensity-modulated radiation therapy (IMRT), reduces the severity of radiation-induced oral mucositis in patients who have been diagnosed with locally advanced, non-metastatic squamous cell carcinoma of the head and neck.

RATIONALE: Giving radiation therapy that uses a 3-dimensional (3-D) image of the tumor to help focus thin beams of radiation directly on the tumor, and giving radiation therapy in higher doses over a shorter period of time, may kill more tumor cells and have fewer side effects. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether radiation therapy is more effective when given alone or together with cetuximab in treating patients with head and neck cancer that has been removed by surgery.

PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared with radiation therapy given together with cetuximab in treating patients who have undergone surgery for locally advanced head and neck cancer.

This randomized phase II-R/III trial studies gemcitabine hydrochloride with or without erlotinib hydrochloride followed by the same chemotherapy regimen with or without radiation therapy and capecitabine or fluorouracil in treating patients with pancreatic cancer that was removed by surgery. Drugs used in chemotherapy, such as gemcitabine hydrochloride, capecitabine, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells. Giving chemotherapy together with or without erlotinib hydrochloride and/or radiation therapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether chemotherapy is more effective when given with or without erlotinib hydrochloride and/or radiation therapy in treating pancreatic cancer.

The purpose of this study is to determine the magnitude of clinical benefit achieved through machine learning assisted radiation treatment planning (MLAP) on post-treatment clinical outcomes such as acute toxicity and patient reported outcomes.

The purpose of this study is to to evaluate the rate of overall survival (OS) at two years in patients with either borderline or locally advanced pancreatic cancer who receive electron beam intraoperative radiation therapy (IORT) following chemotherapy and radiation therapy.
