Aldo-keto reductase family 1, member B10 (AKR1B10), an enzyme that converts retinals into retinols is known to detect in non-small cell lung carcinoma (squamous cell- and adeno-carcinomas), but is barely expressed in normal tissues. Since these types of carcinoma occur frequently in the uterus (like in the lung), AKR1B10 may also be overexpressed in two major types of uterine cancer, cervical cancer (CC), and endometrial cancer (EMC). The objective of this study is to investigate AKR1B10 expression in uterine cancer and to analyze its clinical significance. In samples from uterine cancer patients, AKR1B10 was detected in 6 out of 30 (20.0%) CC cases and 6 out of 38 (15.8%) EMC cases. Statistical analysis indicated that AKR1B10 expression was associated with tumor recurrence after surgery and keratinization of squamous cell carcinoma only in CC. Although retinol (a metabolic product by AKR1B10) was observed in the normal epithelium, the molecule was not observed in cancer cells of AKR1B10-positive CC samples suggesting that the recurrence in CC may not depend on the convert of retinals into retinols via AKR1B10, a potential indicator in the management of patients with CC.

Autonomic nerve preservation is oncologically and functionally excellent and suitable for almost all patients with advanced lower rectal cancer. Intensive chemotherapy is needed for patients whose autonomic nerves were killed in suspicion of nerve invasion.

Summary: The aim of this study was to evaluate the effectiveness of laparoscopic-assisted total colectomy with ileal J-pouch anal anastomosis in comparison with that of conventional open total colectomy in patients with ulcerative colitis. From 1990From until 1999 patients underwent open total colectomy, while 21 patients had laparoscopic-assisted total colectomy. Patients characteristics, perioperative course, and recovery were compared. Differences between the groups were tested using Student's t-test for independent groups and chi-square tests when appropriate. Nasogastric tube could be removed after POD 1.1 vs. 4.8 (p<0.05), the mean time to passage of stool was 1.7(range, 1 to 3) vs. 5.4 (range, 3 to 7) days (p<0.05), and in the laparoscopic group watery stool was soon made solid after POD 24.3 vs. 87.3 (p<0.01). There were no significant differences in the mean operating time and mean estimated operating blood loss between two groups. Postoperative morbidity did not differ significantly between the patients treated conventionally (45.5%) and laparoscopically (33.3%). The findings of this study indicate that laparoscopic-assisted total colectomy improved cosmetic results and to be a safe and effective treatment for the elective surgery of ulcerative colitis.
