3 Clinical Trials for Various Conditions
This study determines whether a positron emission tomography (PET)/computed tomography (CT) 4-point scoring system may predict overall survival for anal squamous cell cancer patients. A 4-point scoring system involving imaging scans may help to predict how patients with anal squamous cell cancer respond to chemoradiation therapy.
This phase II trial studies the side effects of LET-IMPT and standard chemotherapy, and how well they work in treating patients with newly diagnosed stage I-III anal canal squamous cell cancer. LET-IMPT is a type of radiation therapy that uses high energy proton "beamlets" to "paint" the radiation dose into the target and may help to kill tumor cells and shrink tumors. Giving LET-IMPT and standard chemotherapy may work better in treating patients with anal canal squamous cell cancer.
This trial studies the prevalence of anal dysplasia and anal cancer in patients with cervical, vaginal, and vulvar dysplasia and cancer. Studying samples collected from patients in the laboratory may help doctors learn more about the human papillomavirus and how often anal cancer occurs in patients with cervix, vagina, or vulvar cancer.
