[Treatment Strategy for Familial Adenomatous Polyposis Presenting with Obstructive Colorectal Cancer and Concurrent Liver Metastasis].

A 27-year-old man was referred to our hospital for a detailed examination of abdominal distention, bloody stool, anorectal pain, and weight loss. A colonoscopy revealed a circumferential type 2 tumor at 9 cm from the anal verge which was diagnosed as an adenocarcinoma based on biopsy. Contrast-enhanced CT of the abdomen showed an elevated perineal lipid concentration in the rectum(Ra)which was suspicious for clinical T4a stage, and simultaneous S7/8 liver metastasis.

Prognostic significance of preoperative low serum creatine kinase levels in gastric cancer.

Purpose: We evaluated the clinicopathological and prognostic significance of preoperative serum creatine kinase (CK) levels in gastric cancer.

Patients And Methods: The subjects of this retrospective study were 942 patients who underwent surgery without preoperative chemotherapy for gastric cancer (643 men and 299 women), excluding Stage IV gastric cancer, between January, 2001 and December, 2020. We set the cutoff values for CK according to gender, as 64 U/L for men and 57 U/L for women, and evaluated the clinicopathological, prognostic, and gender significance of low CK levels by multivariate analysis.
