My father (65.5 yrs) has been diagnosed with synchronous polyps in a routine colonoscopy. Surgeon found one large Polyp in the Sigmoid and two small in ascending and transverse colon. The histopathology of samples taken during colonoscopy suggested that sigmoid polyp was malignant and transverse colon polyp was benign. He further went for polypetomy to remove two small polyps and Anterior resection to remove sigmoid adinocarcinoma. The histopathological results of the mass classifies it as: T2N0Mx. All 11/11 lymph nodes were found to be reactive and CT of abdomen (prior to surgery) shows all other organs as free of any signs of malignancy. Proximal and distal margins of anastomosis are uninvolved. Microscopic tumor extension into the muscularis propria. Serosa is free of tumor infiltration. Histological measurement of tumor to nearest margin is 5 mm. Perinural invasion is not identified. Lympho-vascular invasion is not identified. Ulcerative lesion measures 3.4x2.8x0.8 cm and the nearest resected end was 4.2 cm away. The other resected end was 10.2 cm away.
The medical oncologist suggested only monitoring and recommended no chemo. Is it ok? or shall we go for second opinion?
Thanks in advance,
Mandar
