RESUMEN

OBJECTIVES: The aim of this study was to determine the necessary reduction in recurrence rate that would make postchemoradiation positron emission tomography (PET)/computed tomography (CT) to direct completion hysterectomy for locally advanced cervical cancer (LACC) cost-effective. METHODS: A decision model evaluated costs and recurrence rates of 2 posttreatment surveillance strategies in LACC: (1) routine surveillance without PET/CT and (2) PET/CT after 3 months to triage to completion hysterectomy. Incremental cost-effectiveness ratios were expressed in dollars per additional cancer recurrence avoided. Model parameters included expected rates of recurrence using each strategy, true- and false-positive rates of posttreatment PET/CT, and major complications of completion hysterectomy. From published data, we modeled an LACC baseline recurrence rate of 32%, PET/CT false-positive rate of 33%, and false-negative rate of 19%. We assumed that PET/CT revealed persistent local cervical cancer in 16% and progressive or distant disease in 6%. Costs of PET/CT, hysterectomy, and treatment for recurrence were based on Medicare reimbursements. A 50% salvage rate with hysterectomy was assumed and varied in sensitivity analysis. RESULTS: Routine use of PET/CT to direct completion hysterectomy was associated with a higher average cost ($16,579 vs $15,450) and a lower recurrence rate (26% vs 32%). The incremental cost-effectiveness ratio of PET was $20,761 per recurrence prevented. When the probability of recurrence after hysterectomy dropped to 25% or less, PET/CT was a dominant strategy. CONCLUSIONS: Routine use of PET/CT to determine which patients may benefit from a completion hysterectomy after chemoradiation for LACC has the potential to be highly cost-effective.

RESUMEN

BACKGROUND: Marriage confers a survival advantage for many cancers but has yet to be evaluated in uterine cancer patients. We sought to determine whether uterine cancer survival varied by self-reported relationship status. METHODS: Data were downloaded from the Surveillance, Epidemiology, and End Results program for women diagnosed with uterine cancer (between 1991 and 2010 in nine geographic regions). Patients with complete clinical data for analysis were categorized as married, single, widowed or other (divorced or separated). Differences in distributions were evaluated using Chi-square, exact and/or Mantel-Haenszel test. Uterine cancer survival was analyzed by Kaplan-Meier method with log-rank test and multivariate Cox regression analysis. RESULTS: Of 47,420 eligible patients, 56% were married, 15% were single and 19% were widows. Married vs. non-married women had a higher likelihood of having low risk (grade 1/2 endometrioid) endometrial cancer and local disease (p<0.0001), and a reduced risk of cancer death (HR=0.8, 95% CI=0.77-0.84). Multivariate evaluation of uterine cancer survival by relationship type indicated that widows consistently had significantly worse uterine cancer survival than single, married and other women in all patients and subset analyses (p<0.0001). CONCLUSION: While marital status is associated with differential uterine cancer survival, evaluation of self-reported relationship by type indicated that the poor outcome observed in widows explained most of the benefit attributed to marriage. This report identifies widows as a new high-risk subpopulation with significantly inferior outcomes potentially benefiting from personalized care and social support.

RESUMEN

STUDY OBJECTIVE: To evaluate if the use of Valleylab mode ("V mode") (Covidien, Mansfield, MA) electrothermal energy for colpotomy during total laparoscopic hysterectomy (LH) results in a smaller margin of thermal injury to the upper vagina compared with traditional cut/coagulate (cut/coag) electrothermal energy. DESIGN: Prospective randomized clinical trial (Canadian Task Force classification I). SETTING: University medical center. PATIENTS: A total of 101 subjects who underwent LH between June 2010 and August 2012. INTERVENTIONS: Subjects were randomized to colpotomy by V mode electrothermal energy or cut/coag electrothermal energy. MEASUREMENTS AND MAIN RESULTS: The primary end point was the median depth of thermal injury measured in millimeters. The secondary end points included the proportion of subjects who developed granulation tissue, induration, infection, or dehiscence at the vaginal cuff at 4 weeks, 3 months, or 6 months postoperatively. There was no significant difference in the median depth of thermal injury in the cut/coag and V mode arms (anterior margin: 0.68 mm vs 0.63 mm [p = .94], posterior margin: 0.66 mm vs 0.70 mm [p = .87], respectively). Twenty-seven percent of subjects in each arm developed at least 1 of the clinical end points at 4 weeks, 3 months, or 6 months postoperatively (granulation tissue: 6%-18% vs 8%-21%, induration: 0%-2% vs 4%-5%, infection: 0%-4% vs 0%-10%, dehiscence: 2% vs 0% in the cut/coag and V mode arms, respectively), with no difference between arms (p = 1.0). CONCLUSION: The V mode does not reduce the depth of thermal injury compared with cut/coag electrothermal energy when used for colpotomy incision during total laparoscopic hysterectomy (Clinical Trials.gov ID: NCT02080546).

RESUMEN

OBJECTIVE: We wished to determine the reduction in the rate of wound complications that would render the use of prophylactic negative pressure wound vacuum therapy (NPWT) cost saving compared to routine incision care (RC) following laparotomy for gynecologic malignancy. METHODS: A decision tree was designed from a payer perspective to compare strategies for incision management following laparotomy for gynecologic malignancy: (1) RC; (2) prophylactic NPWT. Rates of wound complication, antibiotic use, re-hospitalization, re-operation, and home health use were obtained from a published cohort of 431 women who underwent laparotomy for endometrial cancer 2002-2007. Costs were estimated using Medicare reimbursements; cost of NPWT ($200) was obtained from hospital financial department. A 50% reduction in wound complications using NPWT was assigned initially and varied for sensitivity analysis. RESULTS: The mean BMI was 36. The wound complication rate was 31% (37% for BMI>30, 41% for BMI>40). The overall cost of incision care was $104 lower for NPWT than for RC. At the lowest cost of NPWT ($200), the risk of wound complication must be reduced by 33% (relative risk=0.67) for NPWT to achieve cost savings in this cohort. Modeling obese and morbidly obese cohorts, the NPWT resulted in overall cost savings of $163 and $203, respectively, and the risk of wound complication must be reduced by 28% and 25%, respectively, for NPWT to achieve cost savings. CONCLUSION: If the wound complication rate can be reduced by one-third, prophylactic NPWT is potentially cost saving in high-risk women undergoing laparotomy for gynecologic malignancy.

RESUMEN

Despite the increasing availability of palliative care, oncology providers often misunderstand and underutilize these resources. The goals of palliative care are relief of suffering and provision of the best possible quality of life for both the patient and her family, regardless of where she is in the natural history of her disease. Lack of understanding and awareness of the services provided by palliative care physicians underlie barriers to referral. Oncologic providers spend a significant amount of time palliating the symptoms of cancer and its treatment; involvement of specialty palliative care providers can assist in managing the complex patient. Patients with gynecologic malignancies remain an ideal population for palliative care intervention. This review of the literature explores the current state of palliative care in the treatment of gynecologic cancers and its implications for the quality and cost of this treatment.

RESUMEN

OBJECTIVE: To evaluate the optimal cytoreduction (OPT) rate, National Comprehensive Cancer Network (NCCN) treatment guideline compliance rate and patient outcomes for advanced stage epithelial ovarian cancer (EOC) patients at our low volume institution. METHODS: Following IRB approval, records of patients with Stage III-IV EOC, primary peritoneal, or fallopian tube carcinoma completing both primary surgery and adjuvant chemotherapy were reviewed. Patient demographics, clinicopathologic variables, cytoreduction status (optimal or suboptimal), NCCN treatment guideline compliance, and survival were reviewed. Standard statistical tests including the t-test, Chi-square or Fisher's exact test and Kaplan-Meier Survival curves were utilized. RESULTS: Overall, 48 patients met all inclusion criteria. 35(73%) and 13 (27%) achieved optimal and suboptimal cytoreduction, respectively. Median overall survival (OS) for all patients was 37.1 months (95% CI 23.2 - 51.1 months) and NCCN treatment guideline compliance was 85.4%. Compared to sub-optimally cytoreduced patients the optimally cytoreduced patients were significantly older (62.2 vs. 53.5 yrs; p=0.015); no other significant clinicopathologic differences were observed between the two groups. 19 of 48 (39.6%) patients enrolled in an upfront cooperative group trial. Median OS was 43.4 months for optimally compared to 15.6 months in sub-optimally cytoreduced patients (p=0.012). CONCLUSIONS: NCCN treatment guideline compliance, OPT, and median OS rates in our low volume institution are similar to those reported nationally, and argue against using volume alone as a rationale for centralization of care.

RESUMEN

OBJECTIVE: Recurrent cervical cancer has a poor prognosis despite aggressive treatment. We evaluate the comparative-effectiveness of four management strategies in recurrent cervix cancer incorporating risk prognostication categories derived from pooled collaborative group trials: 1) standard doublet chemotherapy; 2) selective chemotherapy (home hospice with no chemotherapy for poorest prognosis patients with remainder receiving standard doublet chemotherapy); 3) single-agent chemotherapy with home hospice; and 4) home hospice. METHODS: A cost-effectiveness decision model was constructed. Survival reduction of 24% was assumed for single-agent chemotherapy and 40% for hospice only compared to standard doublet chemotherapy. Overall survival and strategy cost for each arm were modeled as follows: standard doublet chemotherapy 8.9 months ($33K); selective chemotherapy 8.7 months ($29K); single-agent chemotherapy with home hospice 6.7 months ($16K); and home hospice alone 5.3 months ($11K). Base case analysis assumed equal quality of life (QOL). Sensitivity analyses assessed model uncertainties. RESULTS: Standard doublet chemotherapy for all is not cost-effective compared to selective chemotherapy with an incremental cost-effectiveness ratio (ICER) of $276K per quality-adjusted life-year (QALY). Sensitivity analysis predicted that a 90% improvement in survival is required before standard doublet chemotherapy is cost-effective in the poorest prognosis patients. Selective chemotherapy is the most cost-effective strategy compared to single-agent chemotherapy with home hospice with an ICER of $78K/QALY. Chemotherapy containing regimens become cost-prohibitive with small decreases in QOL. CONCLUSIONS: Supportive care based treatment strategies are potentially more cost-effective than the current standard of doublet chemotherapy for all patients with recurrent cervical cancer and warrant prospective evaluation.

RESUMEN

OBJECTIVE: To determine if early palliative care intervention in patients with recurrent, platinum-resistant ovarian cancer is potentially cost saving or cost-effective. METHODS: A decision model with a 6 month time horizon evaluated routine care versus routine care plus early referral to a palliative medicine specialist (EPC) for recurrent platinum-resistant ovarian cancer. Model parameters included rates of inpatient admissions, emergency department (ED) visits, chemotherapy administration, and quality of life (QOL). From published ovarian cancer data, we assumed baseline rates over the final 6 months: hospitalization 70%, chemotherapy 60%, and ED visit 30%. Published data from a randomized trial evaluating EPC in metastatic lung cancer were used to model odds ratios (ORs) for potential reductions in hospitalization (OR 0.69), chemotherapy (OR 0.77), and emergency department care (OR 0.74) and improvement in QOL (OR 1.07). The costs of hospitalization, ED visit, chemotherapy, and EPC were based on published data. Ranges were used for sensitivity analysis. Effectiveness was quantified in quality adjusted life years (QALYs); survival was assumed equivalent between strategies. RESULTS: EPC was associated with a cost savings of $1285 per patient over routine care. In sensitivity analysis incorporating QOL, EPC was either dominant or cost-effective, with an incremental cost-effectiveness ratio (ICER) <$50,000/QALY, unless the cost of outpatient EPC exceeded $2400. Assuming no clinical benefit other than QOL (no change in chemotherapy administration, hospitalizations or ED visits), EPC remained highly cost-effective with ICER $37,440/QALY. CONCLUSION: Early palliative care intervention has the potential to reduce costs associated with end of life care in patients with ovarian cancer.

RESUMEN

OBJECTIVES: We sought to evaluate the effect of systematic lymphadenectomy (LND) on endometrial cancer-specific survival in an elderly population. METHODS: Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) program from 1988 to 2006. Women who underwent primary hysterectomy for non-serous, non-clear cell endometrial carcinoma were included. Women were stratified by age (<70, 70-79, and ≥ 80) and disease-specific survival (DSS) was analyzed via the Kaplan-Meier method and stratified by postoperative grade. Cohorts were compared using the log-rank test. In a simulated population, the disease-specific survival of women with pre-operative grade 1 endometrial carcinoma was calculated using a weighted average survival accounting for those upgraded at final pathology. RESULTS: Endometrial cancer was identified in 5759 women ≥ 80 years old. Disease specific survival at 5 years for the LND and no LND groups was 93.4% and 94.5% (p=0.36) for grade 1, 84.4% and 85% (p=0.97) for grade 2, and 65.9% and 60.9% (p=0.002) for grade 3. In the simulated pre-operative grade 1 group, 5 year disease-specific survival (DSS) was 91% in the LND group and 92% in the no LND group. CONCLUSION: In women older than 80, systematic lymphadenectomy is associated with improved DSS for high grade, but similar DSS for low grade endometrial cancer, consistent with what is seen with younger women. As there is no clear survival benefit to lymphadenectomy in elderly women presenting with low grade disease, the surgeon should carefully weigh the surgical risks and benefits in this patient population, which may be at higher risk for morbidity.

RESUMEN

This review evaluates the use of robotic-assisted laparoscopic surgery in the treatment of gynecologic malignancies and objectively evaluates the use of these systems in performing radical hysterectomies and surgical staging of gynecologic malignancies. The review focuses on surgical length, blood loss, complications, recovery time, and adequacy of surgical staging of robotic-assisted surgery compared to abdominal and non-robotically assisted laparoscopic surgery for malignancies.

RESUMEN

BACKGROUND: Inactivating somatic mutations in the ARID1A gene are described in a significant fraction of clear cell and endometrioid ovarian cancers leading to loss of the corresponding protein (BAF250a). Expression of BAF250a was examined in clear cell and endometrioid cancers accrued as part of the North Carolina Ovarian Cancer Study, a population-based case-control study, to determine whether loss of expression is associated with clinical and epidemiological features. METHODS: Immunostaining for BAF250a was performed using 212 clear cell and endometrioid ovarian cancers. Associations between loss of BAF250a and clinical and epidemiological features were examined. Variables were analyzed by logistic regression. RESULTS: Loss of BAF250a expression was noted in 96 (45%) of 212 cancers: 34 (41%) of 82 clear cell cases and 62 (48%) of 130 endometrioid cases. There was no relationship between the loss of BAF250a and stage, grade, survival, or epidemiological variables. CONCLUSIONS: These data confirm that loss of the ARID1A-encoded protein BAF250a is a frequent event in the genesis of clear cell and endometrioid ovarian cancers. Loss of BAF250a was not associated with clinical or epidemiologic characteristics. One explanation for these findings is that inactivation of the chromatin remodeling pathway may be a requisite event in the development of these cancers.

RESUMEN

PURPOSE: To compare taxane maintenance chemotherapy, paclitaxel (P) and paclitaxel poliglumex (PP), with surveillance (S) in women with ovarian, peritoneal, or fallopian tube (O/PC/FT) cancer who attained clinical complete response after first-line platinum-taxane therapy. METHODS: Women diagnosed with O/PC/FT cancer who attained clinical complete response after first-line platinum-taxane-based chemotherapy were randomly allocated 1:1:1 to S or maintenance, P 135 mg/m2 once every 28 days for 12 cycles, or PP at the same dose and schedule. Overall survival (OS) was the primary efficacy end point. RESULTS: Between March 2005 and January 2014, 1,157 individuals were enrolled. Grade 2 or worse GI adverse events were more frequent among those treated with taxane (PP: 20%, P: 27% v S: 11%). Grade 2 or worse neurologic adverse events occurred more often with taxane treatment (PP: 46%, P: 36% v S: 14%). At the fourth scheduled interim analysis, both taxane regimens passed the OS futility boundary and the Data Monitoring Committee approved an early release of results. With a median follow-up of 8.1 years, 653 deaths were reported; none were attributed to the study treatment. Median survival durations were 58.3, 56.8, and 60.0 months for S, P, and PP, respectively. Relative to S, the hazard of death for P was 1.091 (95% CI, 0.911 to 1.31; P = .343) and for PP, it was 1.033 (95% CI, 0.862 to 1.24; P = .725). The median times to first progression or death (PFS) were 13.4, 18.9, and 16.3 months for S, P, and PP, respectively. Hazard ratio = 0.801; 95% CI, 0.684 to 0.938; P = .006 for P and hazard ratio = 0.854; 95% CI, 0.729 to 1.00; P = .055 for PP. CONCLUSION: Maintenance therapy with P and PP did not improve OS among patients with newly diagnosed O/tubal/peritoneal cancer, but may modestly increase PFS. GI and neurologic toxicities were more frequent in the taxane treatment arms.

RESUMEN

Objectives: A risk assessment model for metastasis in endometrioid endometrial cancer (EEC) was developed using molecular and clinical features, and prognostic association was examined. Methods: Patients had stage I, IIIC, or IV EEC with tumor-derived RNA-sequencing or microarray-based data. Metastasis-associated transcripts and platform-centric diagnostic algorithms were selected and evaluated using regression modeling and receiver operating characteristic curves. Results: Seven metastasis-associated transcripts were selected from analysis in the training cohorts using 10-fold cross validation and incorporated into an MS7 classifier using platform-specific coefficients. The predictive accuracy of the MS7 classifier in Training-1 was superior to that of other clinical and molecular features, with an area under the curve (95% confidence interval) of 0.89 (0.80-0.98) for MS7 compared with 0.69 (0.59-0.80) and 0.71 (0.58-0.83) for the top evaluated clinical and molecular features, respectively. The performance of MS7 was independently validated in 245 patients using RNA sequencing and in 81 patients using microarray-based data. MS7 + MI (myometrial invasion) was preferrable to individual features and exhibited 100% sensitivity and negative predictive value. The MS7 classifier was associated with lower progression-free and overall survival (p ≤ 0.003). Conclusion: A risk assessment classifier for metastasis and prognosis in EEC patients with primary tumor derived MS7 + MI is available for further development and optimization as a companion clinical support tool.

RESUMEN

OBJECTIVE: Determine if pre-treatment Patient-Generated Subjective Global Assessment (PG-SGA) predicts febrile neutropenia (FN) in gynecologic cancer patients receiving primary combination chemotherapy. METHODS: Following IRB approval, clinicopathologic variables, pre-treatment laboratory values and PG-SGA were recorded from eligible patients. Bone marrow toxicity (CTC 3.0) divided groups of patients: (1) No grade 3 or 4 neutropenia, (2) grade 3 or 4 neutropenia, (3) FN. Statistical analysis with Kruskal-Wallis one-way analysis of variance and a receiver operating characteristic (ROC) curve were performed. RESULTS: 58 patients met study inclusion: 25 in group 1, 28 in group 2, and 5 in group 3. Mean age was 61 and the majority, 42 (72%), had ovarian cancer. Median PG-SGA scores were: 6 (group 1) vs. 7 (group 2) vs. 14 (group 3) (p=0.019). Both median albumin: (1) 4.2 vs. (2) 4.0 vs. (3) 3.4 g/dl (p=0.041), and hemoglobin: (1) 12.1 vs. (2) 11.75 vs. (3) 10.6g/dl (p=0.05) differed between the groups. The overall AUC of the ROC curve for PG-SGA was 0.831 ± 0.064 (95% CI=0.706 to 0.956, p=0.015). Using the ROC, selecting a PG-SGA score of 7.5 to be predictive of febrile neutropenia yields a sensitivity of 100% and a specificity of 60%. When the cutoff value is set at 12.5, the specificity improves to 81% while decreasing sensitivity to 80%. CONCLUSIONS: PG-SGA scores were higher for patients experiencing FN and may be a reasonably predictive marker of FN in patients receiving multi-agent primary chemotherapy and likely benefactors of prophylactic GCSF.

RESUMEN

OBJECTIVE: To evaluate the costs and effectiveness of thromboprophylaxis strategies following laparotomy for ovarian cancer. METHODS: We constructed a decision model to evaluate six strategies for management of postoperative venous thromboembolism (VTE) risk: (1) no thromboprophylaxis; (2) inpatient sequential compression device (SCD); (3) inpatient unfractionated heparin (UFH) 5000 units TID; (4) inpatient low molecular weight heparin (LMWH) 40 mg daily; (5) UFH 5000 units TID×1 month; (6) LMWH 40 mg daily×1 month. Rates of VTE, heparin-induced thrombocytopenia, and significant bleeding for each strategy were obtained from published literature. Costs were based on institutional charges or obtained from the Agency for Healthcare Research and Quality Nationwide Inpatient Sample database for 2008 and average wholesale pricing. Sensitivity analyses were performed to account for uncertainty in estimates. RESULTS: In the base case, UFH×1 month was the least expensive (mean cost $1611) and most effective (VTE risk 1.9%) strategy. LMWH×1 month was equally effective but more expensive ($2197). Inpatient UFH, inpatient LMWH, and SCDs were less effective and more expensive than UFH×1 month. In the sensitivity analysis, cost rankings remained unchanged unless the baseline probability of VTE was assumed <6.5%, the cost of VTE treatment was <$20,000, or the cost of bleeding was >$4500. LMWH×1 month became least expensive when cost was decreased 38%. CONCLUSION: Based on current evidence, extended prophylaxis with UFH is the least expensive and most effective strategy to prevent postoperative VTE following laparotomy for ovarian cancer.

RESUMEN

OBJECTIVE: The purpose of this study was to compare operative outcomes and complications for patients with endometrial cancer who underwent staging by laparoscopy vs laparotomy in a low-volume facility. STUDY DESIGN: Research was conducted with a retrospective cohort of surgical patients with clinical stage I endometrial cancer from 2004-2009. RESULTS: Eighty-six demographically similar patients (50 laparotomy and 36 laparoscopy) were identified. Laparoscopy had less estimated blood loss (339 vs 558 mL; P = .013) and lower rates of transfusion (5.6% vs 24%; P = .02). Laparoscopy was longer (281 vs 202 minutes; P < .0005) but required a shorter hospital stay (2.2 vs 5.5 days; P < .0005). Laparoscopy patients had fewer overall complications (16.7% vs 32%; P = .11). No differences in final surgical stage or lymph node yields between the groups were present. CONCLUSION: Although a longer procedure, laparoscopy had fewer complications and shorter hospital stays. Prolonged operative time, compared with published experience, is potentially the result of unique factors in our center.

RESUMEN

OBJECTIVE: To determine survival and interventions for patients with non-curative gynecologic malignancies based on supportive care enrollment. METHODS: An IRB approved retrospective review identified patients with recurrent/persistent gynecologic cancers from 2002 to 2008. Demographics, therapy, clinicopathologic data, hospice utilization, surgical/invasive procedures and survival were collected. Patients were considered hospice enrollees if they enrolled following recommendation from their provider (HOSPICE); however, patients that declined hospice when recommended were considered (NO HOSPICE), regardless if they ultimately received supportive care. Standard statistical tests including: t-test and Kaplan-Meier with Log Rank were used. RESULTS: Eighty-one patients were identified: 29 patients (36%) NO HOSPICE and 52 (64%) HOSPICE. Mean age was 61. Most patients had ovarian cancer (54.3%), were white (61.7%) and had disease recurrence (72%). Patients utilized a median of 3 anti-neoplastic therapies (range 0-10) for recurrent or progressive/persistent disease. Median time receiving hospice care was 1week for NO HOSPICE patients versus 8weeks HOSPICE patients (p<0.0005). In a subset of patients with recurrent disease, median overall survival for NO HOSPICE patients was 9months (95% CI 5.9-12.1months) versus 17months (95% CI 11.1-22.9months) for HOSPICE patients (p=0.002). NO HOSPICE patients were more likely to have a procedure performed (55% vs. 31%) within 4weeks of their death, including the administration of chemotherapy OR 2.4 (95% CI 1.1-7.1, p=0.036). CONCLUSIONS: While retrospective reviews evaluating hospice are challenging, our data suggest no detrimental impact on survival for hospice patients. Continued evaluation for patients at the end-of-life is necessary in order to optimize resource utilization.

RESUMEN

We report on a case of a suburethral erosion of transobturator tape tracking into the right thigh with abscess formation 20 months from surgery resulting in necrotizing fasciitis. A 64-year-old woman presented with new onset of severe right thigh pain. Physical exam was concerning for a right thigh abscess and she was admitted to general surgery for evaluation. Gynecology was consulted secondary to a complaint of foul vaginal discharge. The patient was noted to have a vaginal mass on the anterior vaginal wall. A computed tomography scan showed a large right medial thigh abscess. The patient was taken for emergency exploratory surgery where an ObTape (Mentor, Santa Barbara, CA, USA) TOT was found eroding through the anterior vaginal wall, extending into the thigh abscess. During removal of the ObTape from her thigh, the entire gracilis muscle was removed due to necrotizing fasciitis and extensive tissue debridement was performed. A wound vac was placed and the patient had an uneventful recovery.

RESUMEN

BACKGROUND: Synchronous primary gynecologic tumors are relatively uncommon with the diagnosis often made following initial surgery. CASE: A multiparous female in her 50s with postmenopausal bleeding was referred to our institution with a biopsy-proven diagnosis of endometrial cancer. Preoperative physical exam revealed a suspicious cervical lesion and upon biopsy she was found to have a signet-ring cell carcinoma of the cervix. Secondary to morbid obesity, the patient was not a candidate for a radical hysterectomy and was treated with curative radiation for stage IB 1 cervical carcinoma and clinical stage I endometrial carcinoma. CONCLUSION: Cervical signet-ring cell carcinoma is an extremely rare pathologic diagnosis. The preoperative discovery of synchronous primary gynecological tumors necessitates individualized planning and treatment.
