Treatment modalities for patients with an obstruction due to an irresectable malignant stenosis of the colon are: a palliative colostomy proximal of the obstruction, radiotherapy, laser therapy, cryosurgery, and photodynamic therapy. In 4 patients, 3 men and 1 woman of 70, 66, 74, and 38 years respectively with obstruction ileus caused by an irresectable distal colonic carcinoma, a self-expanding wallstent was successfully placed endoscopically in the stenosis of the latter three as a palliative measure, resulting in the unimpeded passage of faeces and intestinal gas.

Purpose: Radiotherapy (RT) is a well-established modality for treating malignancies, but its role in treatment of benign lesions has not been well explored. Herein, we present a retrospective analysis of a 7-year data regarding the benefit and the safety profile of RT for treating benign tumors in our institute.
Materials And Methods: Data of 23 patients who received RT for benign tumors from January 2015 to April 2022 were retrieved, and a retrospective analysis was conducted.

Background: Pancreatic adenocarcinoma (PaC) still has a dismal prognosis, and despite medical advances, a bleak 5-year survival rate of only 8%, largely due to late diagnosis and limited curative surgical options for most patients. Frontline palliative treatment shows some survival advantages. However, the high disease mortality is accompanied by high morbidity including cancer-related pain and additional symptoms, which strongly impair patients' quality of life (QOL).
