Treat Colorectal Tumors With Proton Therapy

Colorectal cancer starts as a growth on the inner lining of the colon or rectum. These growths, called polyps, may develop into cancer and grow into the wall of the colon or rectum over time.

Are There Symptoms of Colorectal Cancer?

A colorectal screening is recommended for those over 40 years of age or with a family history of colon cancer, and if symptoms occur like bowel habit changes, rectal bleeding, bloody stools and unexplained weight loss.

How Is Colorectal Cancer Treated?

Colorectal cancer is treated with surgery, chemotherapy and radiation therapy.

A tumor in the colon or rectum, in close proximity to other critical structures such as the small bowel, bladder and rectum, makes precise targeting of radiation a critical factor in treatment. That’s why radiation with proton therapy may be prescribed. Proton therapy applies a concentrated dose of radiation directly to the tumor that has formed in the colon or rectum, limiting harm to the vital, healthy tissue surrounding it.

The Maryland Proton Treatment Center (MPTC) Uses Proton Therapy to Treat a Variety of Colorectal Tumors:

• Adenocarcinomas
• Gastrointestinal stromal tumors
• Lymphomas
• Sarcomas
• Carcinoid tumors

Benefits of Proton Therapy to Treat Colorectal Cancer

Improved Quality of Life

Proton therapy delivers a high dose of radiation to the tumor while minimizing radiation exposure to surrounding healthy tissue. This can help reduce the risk of side effects, such as radiation-induced damage to the gastrointestinal system that could impact the ability to eat, digest food and drink, and eliminate waste.

Enhanced Treatment Effectiveness

Due to the precise nature of proton therapy, a higher dose of radiation is delivered to cancerous cells while minimizing exposure to healthy tissue, which improves the effectiveness of the treatment and increases the likelihood of long-term cancer control. Proton therapy has been shown to be highly effective in treating colorectal cancers and sparing nearby critical structures, especially with other concerns, such as concordant inflammatory bowel disease or prior radiation exposure.

Proton therapy offers a promising treatment option for colorectal cancer patients, with the potential for improved cancer control and reduced side effects compared to traditional radiation therapy. However, the use of proton therapy may depend on various factors, such as the size and location of the tumor, the patient’s medical history, and their overall health. A multidisciplinary team of medical professionals should evaluate each case to determine the best course of treatment.
