Anal Fistulas in Severe Perineal Crohn's Disease: Mri Assessment in the Determination of Long-Term Healing Rates.

Background & Aims: The European Crohn's and Colitis Organization recommends magnetic resonance imaging (MRI) of anal fistulas to decide on the drug/surgery strategy. No evidence is available on the long-term impact of MRI features on fistula healing. The aim of this study was to evaluate the benefit of combined drug/surgery strategies for the treatment of perianal Crohn's fistulas based on MRI factors at referral.

Clinical, histological, and molecular risk factors for cancer recurrence in patients with stage II colon cancer.

Introduction: The assessment of risk factors of cancer recurrence in patients with stage II colon cancer (CC) is crucial. Our aim was to study the clinical, histological, and molecular features associated with 3-year disease-free survival in a series of consecutive patients with stage II CC treated in three regional digestive oncology centers.

Methods: Clinical and histological data of all patients after curative surgery for stage II CC, treated from 2001 until 2009, were collected retrospectively.
