The preoperative OPNI can be used as a simple prognostic indicator in colorectal carcinoma.

BMI might be a representation of the physical condition brought about by the extent of tumor progression rather than a factor influencing the factors related to gastric carcinoma.

We experienced a rare case of a pedunculated polyp of the appendix, which had been incidentally found by preventive appendectomy performed when providing surgical treatment for rectal carcinoma. A pathological investigation of this polypoid lesion demonstrated branches of fibro-muscular stalks connecting with the lamina muscularis covered by a hyperplastic mucosa, which proved to be consistent with the features of hamartoma. The patient had no external characteristics of Peutz-Jeghers syndrome, including mucocutaneous pigmentation and gastrointestinal polyposis, observed by endoscopy. This case is considered to be a Peutz-Jeghers type polyp of the appendix with a pedunculated form, which is very rare.

PPS could be an easy and useful criteria to stratify prognosis of patients with colorectal carcinoma.

The aim of the present study was to establish a series of criteria based on lymphopenia and thrombocytosis to determine prognosis for patients with colorectal carcinoma. Correlation of preoperative lymphopenia and thrombocytosis with clinicopathological characteristics was investigated in 215 patients with colorectal carcinoma who had undergone surgical treatment. Multivariate analysis showed that the presence of at least either lymphopenia or thrombocytosis (P=0.006), venous invasion (P=0.003) and the stage of tumors (P=0.019) were independent prognostic indicators. Lymphocyte percentage and platelet counts that can be determined using only data from complete blood counts may therefore serve as simple and useful tools to appropriately determine prognosis for patients with colorectal carcinoma.
