conferenceObject LAPAROSCOPIC RIGHT COLECTOMY WITH EXTRACORPOREAL ANASTOMOSIS HAS HIGHER MORBIDITY COMPARED TO INTRACORPOREAL ANASTOMOSIS?(2017) PINTO, R.; GERBASI, L.; CAMARGO, M.; KIMURA, C.; SOARES, D.; BUSTAMANTE-LOPEZ, L.; NAHAS, C.; CAMPOS, F.; CECCONELLO, I.; NAHAS, S.- PROGNOSTIC FACTORS FOR LEFT COLECTOMY FOR COLON CANCER: A TEN YEARS EXPERIENCE OF A SINGLE UNIVERSITY INSTITUTION(2017) NAHAS, Sergio Carlos; NAHAS, Caio Sergio; BUSTAMANTE-LOPEZ, Leonardo Alfonso; PINTO, Rodrigo Ambar; MARQUES, Carlos Frederico Sparapan; CAMPOS, Fabio Guilherme; CECCONELLO, IvanABSTRACT Background: Colorectal cancer is the third most common cancer in the world. In Brazil, it is the leading cause of cancer in the gastrointestinal tract. Aim: To evaluate the preoperative, perioperative, and postoperative risk factors for recurrence and overall survival of patients with left colon cancer operated during a ten-year period. Methods: Patients with left colon cancer surgically treated underwent clinical preoperative workout and cancer staging. The following factors were studied: gender, age, tumor location, T stage, lymph node yield, N stage, M stage, histological type, and tumor differentiation. It was analyzed the influence in five-year overall survival. Results: A total of 173 patients underwent left colectomy for colon cancer. There was a slight predominance of male gender with 50.9%. The mean age was 60.8 years old. Fifteen (8.7%) tumors were located at splenic flexure, 126 (72.8%) at sigmoid colon, and 32 (18.5%) at descending colon. The median length of hospital stay was seven days. Mean survival was 47.5 months. At 60 months seven patients (4%) lost follow-up, 38 patients (21.9%) deceased and 135 patients (78%) were alive. Overall survival time was 48 months. Conclusion: Advanced stages (T3-T4, N+ and M+) were the only factors associated with poor long term survival in left colon cancer.
- Prognostic factors of surgically-treated patients with cancer of the right colon: a ten years' experience of a single universitary institution(2015) NAHAS, Sergio Carlos; NAHAS, Caio Sergio Rizkallah; BUSTAMANTE-LOPEZ, Leonardo Alfonso; PINTO, Rodrigo Ambar; MARQUES, Carlos Frederico Sparapan; CAMPOS, Fabio Guilherme; CECONELLO, IvanBACKGROUND: Colorectal cancer is one of the most common malignancies in the world. There are many controversies in the literature about the prognostic value of primary tumor location. Many studies have shown higher survival rates for tumors in the right colon, and worse prognosis for lesions located more distally in the colon. AIM: To analyze the results of surgical treatment of right-sided colon cancers patients operated in one decade period and identify the prognostic factors that were associated with lower overall survival in stages I-IV patients. METHODS: A retrospective review from the prospectively collected database identified 178 patients with right-sided colon cancer surgically treated with curative intent. Demographic factors (gender and age), tumor factors (site, T stage, N stage, M stage, histological type and tumor differentiation), and lymph node yield were extracted to identify those associated with lower overall survival. RESULTS: Mean age was 65 (±12) years old, and 105 (56.1%) patients were female. Most common affected site was ascending colon (48.1%), followed by cecum (41.7%) and hepatic flexure (10.2%). Mean length of hospital stay was 14 (±2.8) days. T stage distribution was T1 (4.8%), T2 (7.5%), T3 (74.9%), and T4 (12.8%). Nodal involvement was present in 46.0%, and metastatic disease in 3.7%. Twelve or more lymph nodes were obtained in 87.2% of surgical specimens and 84.5% were non-mucinous tumors. Mean survival time was 38.3 (±30.8) months. Overall survival was affected by T stage, N stage, M stage, and final stage. Lymph node involvement (OR=2.06) and stage III/IV (OR=2.81) were independent negative prognostic factors. CONCLUSION: Right-sided colon cancer presented commonly at advanced stage. Advanced stage and lymph node involvement were factors associated with poor long term survival.
