- Minute Type I Gastric Carcinoid With Regional Lymph Node Metastasis(2013) LUPINACCI, Renato Micelli; DIAS, Andre Roncon; MELLO, Evandro Sobroza; KONDO, AndreType I gastric carcinoids are indolent lesions that only rarely metastasize. Until now, lymph node metastasis had only being observed in large (>= 10 mm) and usually invasive lesions (deep submucosa or beyond). This study reports a diminutive (8 mm) gastric carcinoid, limited to the superficial layer of the submucosa (sm1), with no angiovascular invasion, but with a high Ki-67 index (7%) and an involved perigastric lymph node. The aggressive behavior of this lesion ends the previous believe that small and superficial type I gastric carcinoids do not metastasize. This case also indicates that better parameters are necessary to evaluate the malignant potential of these lesions and presents a further support to the value of 2010 World Health Organization classification of gastrointestinal neuroendocrine tumors.
- A modified supralevator pelvic exenteration for the treatment of locally advanced rectal cancer with vaginal and uterine invasion(2013) DIAS, Andre Roncon; NAHAS, Sergio CarlosPost-chemoradiation T4 rectal cancer remains a therapeutic challenge and an aggressive surgical approach is the only chance for a cure. Rectal lesions infiltrating the upper vaginal wall and uterine cervix are usually treated by low anterior resection with en bloc removal of the vagina and uterus. However, failure can occur when one is trying to access the anterior recto-vaginal plane below the tumor, especially in obese patients with a narrow pelvis. The remaining surgical alternatives are aggressive and debilitating. The objective of the study is to describe a modified supralevator pelvic exenteration for selected patients. A new surgical option is added to the armamentarium of the oncologic surgeon. The discussion focuses on the indications for this surgical technique and its advantages, such as the preservation of the anal sphincter and the vagina, thus allowing for fecal continence and sexual activity.
