Radiation-Induced Problems in Colorectal Surgery.

Clin Colon Rectal Surg 2016 Jun;29(2):85-91

Department of Colorectal Surgery, Digestive Diseases Institute, Cleveland Clinic Foundation, Cleveland, Ohio.

Radiotherapy not only plays a pivotal role in the cancer care pathways of many patients with pelvic malignancies, but can also lead to significant injury of normal tissue in the radiation field (pelvic radiation disease) that is sometimes as challenging to treat as the neoplasms themselves. Acute symptoms are usually self-limited and respond to medical therapy. Chronic symptoms often require operative intervention that is made hazardous by hostile surgical planes and unforgiving tissues. Read More

Gastrointestinal toxicity associated to radiation therapy.

Clin Transl Oncol 2010 Aug;12(8):554-61

Hospital Universitario de la Princesa, Madrid, Spain.

Radiation therapy in combination with other treatments, such as surgery and chemotherapy, increases locoregional control and survival in patients with thoracic, abdominal and pelvic malignancies. Nevertheless, significant clinical toxicity with combined treatments may be seen in these patients.
