Background: We previously reported significant associations between genetic variants in insulin receptor substrate 1 (IRS1) and breast cancer risk in women carrying BRCA1 mutations. The objectives of this study were to investigate whether the IRS1 variants modified ovarian cancer risk and were associated with breast cancer risk in a larger cohort of BRCA1 and BRCA2 mutation carriers.

Methods: IRS1 rs1801123, rs1330645, and rs1801278 were genotyped in samples from 36 centers in the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA).

Purpose: The primary objective was to establish noninferiority of laparoscopy compared with laparotomy for recurrence after surgical staging of uterine cancer.

Patients And Methods: Patients with clinical stages I to IIA disease were randomly allocated (two to one) to laparoscopy (n = 1,696) versus laparotomy (n = 920) for hysterectomy, salpingo-oophorectomy, pelvic cytology, and pelvic and para-aortic lymphadenectomy. The primary study end point was noninferiority of recurrence-free interval defined as no more than a 40% increase in the risk of recurrence with laparoscopy compared with laparotomy.

Purpose: The objective was to compare laparoscopy versus laparotomy for comprehensive surgical staging of uterine cancer.

Patients And Methods: Patients with clinical stage I to IIA uterine cancer were randomly assigned to laparoscopy (n = 1,696) or open laparotomy (n = 920), including hysterectomy, salpingo-oophorectomy, pelvic cytology, and pelvic and para-aortic lymphadenectomy. The main study end points were 6-week morbidity and mortality, hospital length of stay, conversion from laparoscopy to laparotomy, recurrence-free survival, site of recurrence, and patient-reported quality-of-life outcomes.

Purpose: To investigate, in a phase III randomized trial, whether postoperative external-beam irradiation to the standard pelvic field improves the recurrence-free interval and overall survival (OS) in women with Stage IB cervical cancers with negative lymph nodes and certain poor prognostic features treated by radical hysterectomy and pelvic lymphadenectomy.

Methods And Materials: Eligible patients had Stage IB cervical cancer with negative lymph nodes but with 2 or more of the following features: more than one third (deep) stromal invasion, capillary lymphatic space involvement, and tumor diameter of 4 cm or more. The study group included 277 patients: 137 randomized to pelvic irradiation (RT) and 140 randomized to observation (OBS).

Background: Both acute renal failure (ARF) and female sex are strongly associated with mortality after open-heart surgery. This study analyzes the effect of sex and race on the incidence of ARF after open-heart surgery and its influence on mortality.

Methods: A total of 24,660 patients underwent open-heart surgery at the Cleveland Clinic Foundation (Cleveland, OH) from 1993 to 2000.

Purpose: The endorectal advancement flap is a surgical procedure used in the treatment of anorectal and rectovaginal fistulas. There is a wide range of success rates published in the literature. This study was undertaken to examine the success rate of primary endorectal advancement flap in our own institution.
