Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
