Nerve block for radiation pain during anal cancer treatment
Part of Cancer, Digestive system clinical trials.
This study tests a nerve block procedure (ganglion impar neurolysis) to reduce severe pain caused by radiation therapy for anal or perianal skin cancer. It may help you manage pain while you continue your cancer treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have localized anal cancer or perianal skin cancer
- You are about to start or have already started chemotherapy and radiation therapy for your cancer
- You consistently rate your pain as 5 or higher on a 0–10 scale, or pain is interfering with your daily life
- You are 18 years or older
- You are willing to fill out questionnaires and sign a consent form

This study tests a procedure that blocks nerves in the upper belly to relieve pain from advanced cancer. It may help people whose pain is not controlled by strong pain medicines.
This trial tests two types of pain-relieving nerve blocks for people with severe cancer pain in the pelvis or perineum that has not improved enough with standard stepwise pain medicines. It may help reduce pain and lessen bothersome side effects from pain pills.
This trial tests whether a specific radiation plan that avoids treating the inner groin lymph nodes can treat early-stage anal cancer effectively while reducing side effects. Participants may also receive chemotherapy if they are eligible.
This trial tests a new, more precise type of radiation therapy for anal cancer. It uses daily MRI scans to adjust the radiation dose based on how the tumor shrinks, aiming to give stronger treatment to the cancer while protecting healthy tissue.
This trial tests an adaptive, image-guided radiation plan for anal canal squamous-type cancers. It may help deliver effective treatment while adjusting the radiation based on how your body and tumor respond.
This trial tests a combination of the immunotherapy drug pembrolizumab, two chemotherapy drugs (carboplatin and paclitaxel), and radiation for people with early-stage anal cancer who cannot take the usual chemotherapy. The goal is to see if this approach is safe and effective as an alternative treatment.
