Trial Identification

Brief Title: Adaptive Radiation in Anal Cancer

Official Title: Feasibility Study of Adaptive Radiotherapy for the Treatment of Locally-Advanced Anal Squamous Cell Carcinoma

Study ID: NCT05838391

Study Description

Brief Summary: This is a 20 patient pilot study to examine the feasibility of dose-adapted radiation therapy for the treatment of locally advanced anal squamous cell cancer. The tumor and a patient's anatomy may change during radiation treatment and daily adaption of the radiation plan (i.e., a new daily plan based on the anatomy of the day) may help to maximize the dose to the tumor and minimize the radiation dose to the normal surrounding organs.

Detailed Description: The standard treatment for Human Papilloma Virus (HPV)-positive locally advanced anal cancer (described as a tumor that is greater than 4 cm in size, or with positive lymph nodes) is 54 Gy of radiation treatment to the anal canal and primary tumor planning total volume (PTV), 50.4-54 Gy to positive nodal PTV and 45 Gy to elective lymph node PTV with 5-fluorouracil (5-FU) and mitomycin-C chemotherapy administered at the same time as radiation in 30 fraction (treatments) delivery. During the six week course of radiotherapy, there is often a notable decrease in volume of the tumor (both primary and regional nodes), as early as one week into treatment, detected on weekly on-board Cone Beam Computed Tomography (CBCT), which is a scan done on the treatment machine while patients receive radiation to ensure that the tumor is being treated and normal tissue is not. However, CT simulation (a CT scan used to plan radiation treatment) and re-planning of the treatment to account for the tumor shrinkage are not routinely performed due to time, patient inconvenience and staffing resources. As such, daily adaptive radiation, which can generate a new CT-based plan using the anatomy of the day, may be a time efficient method to both plan and treat the patient.
