Accelerated Premalignant Polyposis and Second Colon Cancers: Incriminating Immunosuppression, Radiotherapy, and Systemic Chemotherapy Agents.

摘要

We believe that timing for colonoscopic surveillance in these patients should be different from the general population in order to identify promptly these rapidly progressive neoplasms. Screening for second malignancies should be considered early after remission of the primary cancer is documented, especially when a prolonged survival or a cure is anticipated. We also recommend consideration be given to increasing the frequency of colonoscopy in these cohorts. Future studies are required in order to establish the optimal time interval for surveillance colonoscopy in these high-risk individuals.
