ADENOCARCINOMA OF COLON AND RENAL CARCINOMA OF CLEAR SYNCHRONIC CELLS: A CASE REPORT

This study reported the case of a patient with a diagnosis of colonic and renal synchronic tumors: Moderately differentiated adenocarcinoma of sigmoid and renal carcinoma of the synchronic clear cell variant in a 66-year-old female patient who were surgically resected in a single approach in an Oncology service in the interior of the State of Ceará, Brazil. For data collection, records of the medical record, interview with the patient and the surgeon responsible for the case, photographic record of the diagnostic methods to which the patient was submitted, and literature review were used. It followed all the ethical principles established by law 466/2012. From this study it was concluded that: a) the incidence of colorectal cancer and synchronic renal cell carcinoma ranges from 0.03 to 4.85% in the analyzed literature, b) risk factors for synchronic tumors include genetic and environmental factors; c) renal cell carcinoma is usually diagnosed by performing preoperative tests for staging of abdominal carcinomas. Still, large prospective studies are necessary to define the best therapeutic strategy, however, some authors have confirmed that simultaneous laparoscopic resection of both neoplasms is possible and presents low morbidity and mortality. Keywords: synchronic tumor, colon cancer, renal cancer.
