Background/Aim:
The evaluation of radiotherapy toxicity in oncologic IBD patients. Defining the optimal patient and treatment factors that would be able to reduce the risk to organs.
Materials And Methods:
A review of all published radiotherapy trials was performed to identify the clinical and treatment factors of inflammatory bowel disease's patients treated for different solid tumors.
Results:
Overall, acute (Grade ≥ 3) gastrointestinal complications attributable to RT ranged between 20-21% of the treated patients. A late Grade ≥ 3 gastrointestinal toxicity was developed in a range between 8-29%.
Conclusion:
A special attention should be given to the description of IBD location, activity status, concurrent chemotherapy, irradiation dose and technique, in order to minimize post-irradiation morbidity. It is not easy to distinguish late morbidity attributable to radiotherapy due to the IBD itself.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
