OBJECTIVE To determine long-term survival and predictors of recurrence in patients with platinum-treated ovarian cancer who were followed for 10 years after second-look laparotomy with negative findings. METHODS Records were reviewed of 91 consecutive patients with negative findings on second-look laparotomy after platinum-based chemotherapy between January 1978 and January 1987. Statistical analysis used Kaplan-Meier survival curves, Cox proportional hazards, and multiple logistic regression. RESULTS Mean age of patients was 57 (range 30-79) years. Distribution by stage and grade was as follows: stage I, ten; II, 18; III, 57; IV, six; grade 1, 18; 2, 28; 3, 45. Forty-seven of 91 women had optimal initial cytoreduction. Recurrence-free survival rates for all subjects were 75% at 2 years, 55% at 5 years, and 52% at 10 years. For women with stage I disease, the recurrence-free survival rate was 90% at 2, 5, and 10 years. For women with stage II disease, recurrence-free survival rates were 78, 72, and 66% at 2, 5, and 10 years, respectively. Patients with stage III or IV disease had recurrence-free survival rates of 72, 44, and 40% at 2, 5, and 10 years, respectively. Risk of recurrent disease was related to tumor stage (relative risk [RR] 2.02; 95% confidence interval [CI] 1.2, 3.3; P = .005), grade (RR 2.00; 95% CI 1.3, 3.2; P = .004), and presence of a residual tumor of more than 2 cm at the end of initial surgery (RR 3.19; 95% CI 1.2, 8.5; P = .02). CONCLUSION Ovarian cancer patients face an appreciable risk of recurrence in the first 5 years after second-look laparotomy with negative findings after platinum-based chemotherapy, but those who remain disease free at 5 years have excellent long-term survival rates. Tumor stage, grade, and presence of a residual tumor of more than 2 cm after initial surgery are significant predictors of recurrence.

Hormone Replacement Therapy and Life Expectancy After Prophylactic Oophorectomy in Women With BRCA1/2 Mutations: A Decision Analysis

Katrina Armstrong; J. Sanford Schwartz; Thomas C. Randall; Stephen C. Rubin; Barbara L. Weber

PURPOSE The decision about prophylactic oophorectomy is difficult for many premenopausal women with BRCA1/2 mutations because of concerns and controversy about the use of hormone replacement therapy (HRT) after oophorectomy. PATIENTS AND METHODS A Markov decision analytic model used the most current epidemiologic data to assess the expected outcomes of prophylactic oophorectomy with or without HRT (to age 50 years or for life) in cohorts of women with BRCA1/2 mutations. Sensitivity analyses were conducted to assess the impact of alternative assumptions about effects of HRT, effects of prophylactic oophorectomy, and risks of cancer associated with BRCA1/2 mutations. RESULTS In our model, prophylactic oophorectomy lengthened life expectancy in women with BRCA1/2 mutations, irrespective of whether HRT was used after oophorectomy. This gain ranged from 3.34 to 4.65 years, depending on age at oophorectomy. Use of HRT after oophorectomy was associated with relatively small changes in life expectancy (+0.17 to -0.34 years) when HRT was stopped at age 50, but larger decrements in life expectancy if HRT was continued for life (-0.79 to -1.09 years). HRT was associated with a gain in life expectancy of between 0.39 and 0.79 years for mutation carriers undergoing both prophylactic mastectomy and oophorectomy. CONCLUSION On the basis of the results of this decision analysis, we recommend that women with BRCA1/2 mutations undergo prophylactic oophorectomy after completion of childbearing, decide about short-term HRT after oophorectomy based largely on quality-of-life issues rather than life expectancy, and, if using HRT, consider discontinuing treatment at the time of expected natural menopause, approximately age 50 years.

OBJECTIVE To compare peri- and post-operative complications and outcomes of robotic-assisted surgical staging with traditional laparoscopic surgical staging for women with endometrial cancer. METHODS A retrospective chart review of cases of women undergoing minimally invasive total hysterectomy and pelvic and para-aortic lymphadenectomy by a robotic-assisted approach or traditional laparoscopic approach was conducted. Major intraoperative complications, including vascular injury, enterotomy, cystotomy, or conversion to laparotomy, were measured. Secondary outcomes including operative time, blood loss, transfusion rate, number of lymph nodes retrieved, and the length of hospitalization were also measured. RESULTS 275 cases were identified-102 patients with robotic-assisted staging and 173 patients with traditional laparoscopic staging. There was no significant difference in the rate of major complications between groups (p=0.13). The mean operative time was longer in cases of robotic-assisted staging (237 min vs. 178 min, p<0.0001); however, blood loss was significantly lower (109 ml vs. 187 ml, p<0.0001). The mean number of lymph nodes retrieved were similar between groups (p=0.32). There were no significant differences in the time to discharge, re-admission, or re-operation rates between the two groups. CONCLUSION Robotic-assisted surgery is an acceptable alternative to laparoscopy for minimally invasive staging of endometrial cancer. In addition to the improved ease of operation, visualization, and range of motion of the robotic instruments, robotic surgery results in a lower mean blood loss, although longer operative time. More data are needed to determine if the rates of urinary tract injuries and other surgical complications can be reduced with the use of robotic surgery.

Differences in Treatment and Outcome Between African-American and White Women With Endometrial Cancer

Thomas C. Randall; Katrina Armstrong

PURPOSE To investigate disparities in treatment and outcomes between African-American and white women with endometrial cancer. PATIENTS AND METHODS We analyzed 1992 to 1998 Surveillance, Epidemiology, and End Results data for 21,561 women with epithelial cancers of the endometrium. Sequential Cox proportional hazard models were used to determine the association between tumor characteristics (stage, grade, and histologic type), sociodemographic characteristics (age and marital status), and treatment (surgery and radiation therapy) and the racial difference in mortality. RESULTS The unadjusted hazard ratio (HR) for death from endometrial cancer for African-American women compared with white women was 2.57. However, African-American women were significantly more likely to present with advanced-stage disease and have poorly differentiated tumors or tumors with an unfavorable histologic type and were significantly less likely to undergo definitive surgery at all stages of disease. Adjusting for tumor and sociodemographic characteristics lowered the HR for African-American women to 1.80. Further adjustment for the use of surgery reduced the HR to 1.51. The association between surgery and survival was stronger among white women (HR, 0.26) than among African-American women (HR, 0.44). CONCLUSION African-American women with endometrial cancer are significantly less likely to undergo primary surgery and have significantly shorter survival than white women with endometrial cancer. Racial differences in treatment are associated with racial differences in survival. The association between use of surgery and survival is weaker among African-American than white women, raising questions about potential racial differences in the effectiveness of surgery.

PURPOSE Chemotherapy for ovarian cancer is usually administered by medical oncologists (MOs) or gynecologic oncologists (GOs). GOs perform a broad spectrum of surgical and medical activities while managing a limited number of diseases; MOs specialize in the administration of chemotherapy but manage a broad array of diseases. We asked whether survival, treatment, and toxicity differed according to the type of specialist providing the chemotherapy after surgery. PATIENTS AND METHODS Using Surveillance, Epidemiology, and End Results (SEER)--Medicare data for patients 65 years old from 1991 through 2001 from eight SEER sites, we identified 344 patients with ovarian cancer who were treated with chemotherapy by a GO after surgery. Using optimal matching and propensity scores based on 36 characteristics, we matched these patients to 344 similar patients who were operated on and staged by the same type of surgeon but who received chemotherapy from an MO. RESULTS MOs administered chemotherapy over more weeks than did the GOs (16.5 v 12.1 weeks, respectively; P < .0023), and MO patients had substantially more weeks that included chemotherapy-associated adverse events than GO patients (16.2 v 8.9 weeks, respectively; P < .0001). However, there was no difference in 5-year survival rate between the GO and MO groups (35% v 34%, respectively; P = .45). CONCLUSION GO- and MO-treated patients who were closely matched on prognostic characteristics experienced very different rates of chemotherapy-associated adverse events and very different chemotherapy treatment styles by specialty type; however, their survival was virtually identical.

CYTOREDUCTIVE SURGERY FOR OVARIAN CANCER

Thomas C. Randall; Stephen C. Rubin

Cytoreductive surgery is a crucial component of the management of cancer of the ovary. Surgical cytoreduction of ovarian cancer volume has been associated with an increase in survival in all settings in which it has been studied. This association seems strongest, and the benefits of aggressive surgery are generally greatest, in patients with chemosensitive disease. Effective surgical management of ovarian cancer, therefore, requires competence in surgical anatomy and cytoreductive techniques and a thorough understanding of the patients disease status and therapeutic goals.

Vaginal cuff dehiscence after robotic total laparoscopic hysterectomy.

Barbara Robinson; John B. Liao; Sarah Adams; Thomas C. Randall

BACKGROUND: Vaginal cuff dehiscence with small bowel evisceration after hysterectomy is a rare event that may be occurring more frequently with the advent of robotic laparoscopic hysterectomies. CASES: Two women underwent robotic total laparoscopic hysterectomy for menorrhagia and stage I endocervical adenocarcinoma, respectively. Each presented 7–8 weeks postoperatively with abdominal pain and vaginal pressure after intercourse. The small bowel protruded into the vagina through the dehisced vaginal cuff. Both cuffs were repaired vaginally with delayed absorbable suture. One repair required revision 7 weeks after the initial repair. CONCLUSION: Robotic total laparoscopic hysterectomy may be associated with increased risk of vaginal cuff dehiscence and small bowel evisceration. This observation may be because of thermal spread and cuff tissue damage from electrosurgery used for colpotomy.

Vaginal cuff recurrence of endometrial cancer treated by laparoscopic-assisted vaginal hysterectomy.

Christina S. Chu; Thomas C. Randall; Christina A. Bandera; Stephen C. Rubin

BACKGROUND Laparoscopic-assisted vaginal hysterectomy (LAVH) has been suggested as an alternative to total abdominal hysterectomy (TAH) for the treatment of early endometrial cancer. Although studies have reported good results with equivalent rates of recurrence and survival, the need for use of intrauterine manipulators during the LAVH raises the concern for operative dissemination of tumor cells. CASES We report three patients with stage I, noninvasive or superficially invasive endometrial cancer with vaginal cuff recurrence within 9 months of treatment by LAVH. CONCLUSION While LAVH may be a technically acceptable alternative to TAH for the management of early-stage endometrial cancer, its routine use should be undertaken with caution, as the long-term risks for recurrence and survival have yet to be defined in a randomized, controlled fashion.

Cost-effectiveness of raloxifene and hormone replacement therapy in postmenopausal women: Impact of breast cancer risk

Katrina Armstrong; Tze-Ming Chen; Daniel Albert; Thomas C. Randall; J. Sanford Schwartz

OBJECTIVE To examine the life expectancy and cost‐effectiveness of hormone replacement therapy (HRT) and raloxifene therapy in healthy 50‐year‐old postmenopausal women. METHODS We performed a cost‐effectiveness analysis using a Markov model, discounting the value of future costs and benefits to account for their time of occurrence. RESULTS Both HRT and raloxifene therapy increase life expectancy and are cost‐effective relative to no therapy for 50‐year‐old postmenopausal women. For women at average breast cancer and coronary heart disease risk, lifetime HRT increases quality‐adjusted life expectancy more (1.75 versus 1.32 quality‐adjusted life years) and costs less (
