RESUMO

OBJECTIVES: To assess the efficacy and toxicity of paclitaxel and carboplatin (PC) compared to bleomycin, etoposide, and cisplatin (BEP) for treatment of newly diagnosed Stage IIA-IV or recurrent chemotherapy-naive ovarian sex cord-stromal tumors (SCST). METHODS: This phase II noninferiority trial randomly assigned patients to receive PC (6 cycles P 175 mg/m2 and C AUC = 6 IV every 3 weeks), or BEP (4 cycles B 20 units/m2 IV push day 1, E 75 mg/m2 IV days 1-5, and cisplatin 20 mg/m2 IV days 1-5 every 3 weeks). The primary endpoint was progression- free survival (PFS). This trial is registered with ClinicalTrials.gov, NCT01042522. RESULTS: At the interim analysis, 63 patients (31 PC and 32 B.P. had accrued between Feb 8, 2010 and Apr 30, 2020. Median age was 48 years. 87% had granulosa cell tumors. 37% had measurable disease. The DSMB closed accrual early for futility of PC arm. The futility analysis was supported by an estimated HR = 1.11 [95% CI: 0.57 to 2.13] which exceeded the pre-determined threshold for non-inferiority (1.10). Median PFS was 27.7 months [11.2 to 41.0] for PC and 19.7 months for BEP [95% CI: 10.4-52.7]. PC patients had fewer grade 3 or higher adverse events (PC 77% vs BEP 90%). CONCLUSIONS: The study met its pre-specified criterion for stopping early for futility and so failed to demonstrate non-inferiority of PC versus BEP in ovarian SCSTs, in a non-inferiority test with a hazard ratio margin of 1.1. Both PC and BEP may be considered in patients with advanced/recurrent SCST.

RESUMO

Vulvar cancer is annually diagnosed in an estimated 6,470 individuals and the vast majority are histologically squamous cell carcinomas. Vulvar cancer accounts for 5% to 8% of gynecologic malignancies. Known risk factors for vulvar cancer include increasing age, infection with human papillomavirus, cigarette smoking, inflammatory conditions affecting the vulva, and immunodeficiency. Most vulvar neoplasias are diagnosed at early stages. Rarer histologies exist and include melanoma, extramammary Paget's disease, Bartholin gland adenocarcinoma, verrucous carcinoma, basal cell carcinoma, and sarcoma. This manuscript discusses recommendations outlined in the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for treatments, surveillance, systemic therapy options, and gynecologic survivorship.

RESUMO

OBJECTIVE: Assess outcomes of interval debulking surgery (IDS) after neoadjuvant chemotherapy via minimally invasive surgery (MIS) compared with laparotomy in patients with advanced epithelial ovarian cancer. METHODS: Patients diagnosed with stage IIIC or IV epithelial ovarian cancer between 2013 and 2018 who received neoadjuvant chemotherapy and IDS were identified in the National Cancer Database. Primary outcome was overall survival. Secondary outcomes were 5-year survival, 30- and 90-day postoperative mortality, extent of surgery, residual disease, hospitalization duration, surgical conversions, and unplanned readmissions. Propensity score matching was used to compare MIS and laparotomy for IDS. Association of treatment approach with overall survival was assessed using Kaplan-Meier method and Cox regression. Sensitivity analysis was conducted for effect of unmeasured confounders. RESULTS: A total of 7897 patients met inclusion criteria; 2021 (25.6%) underwent MIS. Percentage undergoing MIS increased from 20.3%-29.0% over the study period. After propensity score matching, median overall survival was 46.7 months in the MIS group versus 41.0 months in the laparotomy group [hazard ratio (HR) 0.86 (95%CI 0.79-0.94)]. Five-year survival probability was higher in MIS versus laparotomy (38.3% vs 34.8%, p < 0.01). There was lower 30- and 90-day mortality (0.3% vs 0.7% [p = 0.04] and 1.4% vs 2.5% [p = 0.01], respectively), shorter length of stay (median 3 vs 5 days, p < 0.01), lower residual disease (23.9% vs 26.7%, p < 0.01), and lower additional cytoreductive procedures (59.3% vs 70.8%, p < 0.01) in MIS compared to laparotomy, with similar rates of unplanned readmission (2.7% vs 3.1%, p = 0.39). CONCLUSIONS: Patients who undergo IDS by MIS have similar overall survival and decreased morbidity compared with laparotomy.

RESUMO

Adenocarcinoma of the endometrium (also known as endometrial cancer, or more broadly as uterine cancer or carcinoma of the uterine corpus) is the most common malignancy of the female genital tract in the United States. It is estimated that 65,950 new uterine cancer cases will have occurred in 2022, with 12,550 deaths resulting from the disease. Endometrial carcinoma includes pure endometrioid cancer and carcinomas with high-risk endometrial histology (including uterine serous carcinoma, clear cell carcinoma, carcinosarcoma [also known as malignant mixed Müllerian tumor], and undifferentiated/dedifferentiated carcinoma). Stromal or mesenchymal sarcomas are uncommon subtypes accounting for approximately 3% of all uterine cancers. This selection from the NCCN Guidelines for Uterine Neoplasms focuses on the diagnosis, staging, and management of pure endometrioid carcinoma. The complete version of the NCCN Guidelines for Uterine Neoplasms is available online at NCCN.org.

RESUMO

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States, with less than half of patients living >5 years following diagnosis. The NCCN Guidelines for Ovarian Cancer provide recommendations for the diagnosis, evaluation, treatment, and follow-up for patients with ovarian, fallopian tube, and primary peritoneal cancers. These NCCN Guidelines Insights summarize the panel discussion behind recent important updates to the guidelines, including revised guidance on alternative chemotherapy regimens for patients with advanced age and/or comorbidities, a new algorithm for recurrent low-grade serous carcinoma based on developing research and novel therapeutic agents, and updated language regarding tumor molecular analysis applications in ovarian cancer.

RESUMO

Joe V. Meigs was a visionary clinician and an early adopter of radical techniques in the surgical treatment of ovarian cancer. His 1934 textbook "Tumors of the Female Pelvic Organs", consolidated his approach to this "hopeless" disease, with pearls on diagnosis, outcomes, and even speculations about the benefits of minimally invasive surgery. Decades before adjuvant chemotherapy would prove of value, and in an era when sophisticated statistics were unheard of, he nonetheless tried to eke out what benefits he could using the methods available in his time. We transition his original findings and observations through the advent of platinum-based chemotherapy, retrospective cohort studies supporting the benefits of primary debulking, and finally the long-awaited randomized controlled trial. We aim to provide historical context for the underpinnings of how cytoreductive surgery has evolved into its current role in the treatment of advanced ovarian cancer.

RESUMO

PURPOSE: To identify clinical and non-clinical factors associated with utilization of primary cytoreductive surgery (PCS) or neoadjuvant chemotherapy (NACT) in women with advanced stage epithelial ovarian cancer (EOC). METHODS: Using the National Cancer Database, we identified women with stage IIIC and IV EOC diagnosed from 2012 to 2014. The primary outcome was receipt of NACT, defined in the primary analysis as utilization of chemotherapy as the first cancer-directed therapy, irrespective of whether interval surgery was performed. Univariable and multivariable associations between clinical and non-clinical factors and receipt of NACT were investigated using mixed-effect logistic regression models. A secondary analysis excluded women who received primary chemotherapy but did not receive interval cytoreductive surgery. RESULTS: Among 17,302 eligible women, 10,948 (63.3%) underwent PCS and 6354 (36.7%) received NACT. Older age, stage IV disease, high-grade, and serous histology were associated with receipt of NACT in univariate (p<0.001) and multivariable analyses (p<0.001). Analysis of non-clinical factors revealed that residency in the Northeast region and receipt of treatment closer to home were associated with NACT in univariate (p<0.05) but not multivariable analysis (p>0.05). In multivariable analysis, African-American race/ethnicity (p=0.04), low-income level (p=0.02), treatment in high-volume centers (p<0.01), and insurance by Medicare or other government insurance (p<0.001) were associated with receipt of NACT. When women who received no surgery were excluded, all factors that were independent predictors of NACT in the main analysis remained significant, except for race/ethnicity. CONCLUSIONS: Non-clinical factors were associated with the use of NACT at a magnitude similar to that of clinically relevant factors.

RESUMO

OBJECTIVE: Clinical registries within medical societies have demonstrated the capacity to promote quality improvement. Opportunities for well-designed data repositories could yield reliable national standards for informing reimbursement, determining adherence to care guidelines, maintaining board certification, and developing bundled payment models. Looking to the future, we set out to develop a gynecologic cancer registry serving the members of the Society of Gynecologic Oncology (SGO). METHODS: The SGO Clinical Outcomes Registry (COR) initiated a web-based data entry platform as a foray into developing a functional registry, compiling data elements specific to gynecologic oncology. Endometrial and ovarian cancer patients began enrollment in early 2014. Within one year, 19 sites were participating with the addition of cervical cancer patients in January 2015. RESULTS: To date, >6500 patients are currently entered from 29 sites, and the COR is being queried to address topics of quality improvement, disparities, and cancer outcomes. CONCLUSIONS: The SGO COR has proven the feasibility of developing a functional gynecologic cancer registry, with high uptake, rapid accrual, and ability to investigate topics of quality and outcome using the COR.

RESUMO

BACKGROUND: The American Society of Clinical Oncology recommends that patients with advanced cancer receive dedicated palliative care services early in their disease course. This investigation serves to understand how palliative care services are utilized for ovarian cancer patients in a tertiary referral center. METHODS: We conducted a retrospective review of women treated for ovarian cancer at our institution from 2010 through 2015. Clinical variables included presence and timing of palliative care referral. Data were correlated utilizing univariable and multivariable parametric and non-parametric testing, and survivals were analyzed using the Kaplan-Meier method and cox-proportional hazard models. RESULTS: We identified 391 women treated for ovarian cancer, of whom 68% were diagnosed with stage III or IV disease. Palliative care referral was utilized in 28% in the outpatient (42%) and inpatient (58%) settings. Earlier use of referral was observed in those who never underwent surgical cytoreduction or had interval cytoreductive surgery (p < 0.001). Palliative care referral was independently associated with advanced stage (OR 1.7, p = 0.02), recurrence (OR 2.0, p = 0.002) and hospice referral (OR 6.0, p < 0.001). In 38% of women referral occurred within 30 days of death, and 17% within one week of death. Outpatient initial consultation was associated with an unadjusted 1 year overall survival benefit (p < 0.01) compared to inpatient consultation. CONCLUSIONS: The outcomes in this study suggest a late use of palliative care that is reactionary to patient needs and not a routine component of ovarian cancer care as national guidelines recommend.

RESUMO

OBJECTIVE: To examine temporal trends in treatment and survival among black, Asian, Hispanic, and white women diagnosed with endometrial, ovarian, cervical, and vulvar cancer. METHODS: Using the National Cancer Database (2004-2014), we identified women diagnosed with endometrial, ovarian, cervical, and vulvar cancer. For each disease site, we analyzed race/ethnicity-specific trends in receipt of evidence-based practices. Professional societies' recommendations were used to define these practices. Using data from the Surveillance, Epidemiology, and End Results Program (2000-2009) we analyzed trends in 5-year survival. RESULTS: Throughout the study period black (64.8%) and Hispanic (68.3%) women were less likely to undergo lymphadenectomy for stage I ovarian cancer compared to Asian (79.5%) and white patients (74.6%). Black women were the least likely group to undergo lymphadenectomy in all periods. Among patients with stage II-IV ovarian cancer, 76.6% of white and Asian women received both surgery and chemotherapy, compared to 70.8% of black and 73.9% Hispanic women. Hispanic women with deeply invasive or high-grade stage I endometrial cancer underwent lymphadenectomy less frequently (74.5%) than all other groups (80.7%). Black women were less likely to have chemo-radiotherapy for stage IIB-IVA cervical cancer (75.6% versus 80.4% of all others). Black women were also less likely to have a surgical lymph node evaluation for vulvar cancer (58.8% versus 63.5% of all others). Among women diagnosed with ovarian, endometrial, and cervical cancer, black women had lower five-year survival than other groups. CONCLUSION: Significant racial disparities persist in the delivery of evidence-based care. Black women with ovarian, endometrial, and cervical cancer continue to experience higher cancer-specific mortality than other groups.

RESUMO

OBJECTIVE: For patients with advanced stage epithelial ovarian cancer (EOC), substantial emphasis has been placed on diagnostic tests that can discern which of two treatment options - primary cytoreductive surgery (PCS) or neoadjuvant chemotherapy followed by interval cytoreductive surgery (NACT+ICS) - optimizes patient-level outcomes. Our goal was to project potential life expectancy (LE) gains that could be achieved by use of such a test. METHODS: We developed a microsimulation model to project LE for patients with stage IIIC EOC. We compared: a "standard-of-care" strategy, in which patients were triaged to PCS vs. NACT+ICS based on current clinical practice; and a "test" strategy, in which patients were triaged based on results of a hypothetical test. We identified those test performance characteristics for which the test strategy outperformed the standard-of-care strategy, from a LE standpoint. Effects of parameter uncertainty were evaluated in sensitivity analysis. RESULTS: Even with a perfect test, the LE gain was modest (LE with test vs. standard-of-care strategy=67.6 vs. 66.4months; LE gain=1.2months). In order to outperform the standard-of-care, the test had to have a high probability of correctly identifying "resectable" patients at PCS (i.e. those for whom complete or optimal cytoreduction would be possible); this test property was more important than correct triage of unresectable patients to NACT+ICS. Results were sensitive to the proportion of patients whose underlying disease was resectable at PCS. CONCLUSION: Diagnostic tests that are designed to triage patients with advanced stage EOC will likely have only a modest effect on LE.

RESUMO

PURPOSE: The aim of this study was to determine factors associated with the adoption of minimally invasive surgery (MIS) compared with laparotomy in the treatment of endometrial cancer and to compare surgical outcomes and survival between these two surgical modalities. METHODS: We utilized the National Cancer Data Base (NCDB) to identify women diagnosed with presumed early-stage endometrial cancer between 2010 and 2012. We also identified factors associated with the performance of MIS and utilized propensity score matching to create a matched cohort of women who underwent minimally invasive staging surgery or laparotomy for surgical staging. RESULTS: Overall, 20,346 women were eligible for inclusion in the study; 12,604 (61.9%) had MIS, while 7742 (38.1%) had a laparotomy. African American race (odds ratio [OR] 0.54, 95% confidence interval [CI] 0.49-0.60], Hispanic ethnicity (OR 0.70, 95% CI 0.61-0.80), Charlson score >2 (OR 0.79, 95% CI 0.69-0.91), high-grade histology (OR 0.63, 95% CI 0.59-0.68), presumed clinical stage II disease (OR 0.53, 95% CI 0.46-0.60), and surgery at a community cancer program (OR 0.46, 95% CI 0.39-0.55) or in the Midwest region (OR 0.70, 95% CI 0.64-0.76) were associated with a decreased likelihood of having MIS, while private insurance (OR 1.69, 95% CI 1.45-1.97) and highest quartile median household income (OR 1.13, 95% CI 1.03-1.24) were associated with an increased likelihood of having MIS. After propensity score matching, there was no association between minimally invasive staging surgery and 3-year overall survival (hazard ratio 1.03, 95% CI 0.92-1.16). CONCLUSION: There are notable racial, ethnic, socioeconomic, and geographic variations in the utilization of MIS for endometrial cancer staging in the US. After controlling for the aforementioned factors, MIS had a similar 3-year survival compared with laparotomy in women undergoing staging surgery for endometrial cancer.

RESUMO

Clinical outcomes research seeks to understand the real-world manifestations of clinical care. In particular, outcomes research seeks to reveal the effects of pharmaceutical, procedural, and structural aspects of healthcare on patient outcomes, including mortality, disease control, toxicity, cost, and quality of life. Although outcomes research can utilize interventional study designs, insightful use of observational data is a defining feature of this field. Many questions in gynecologic oncology are not amenable to investigation in randomized clinical trials due to cost, feasibility, or ethical concerns. When a randomized trial is not practical or has not yet been conducted, well-designed observational studies have the potential to provide the best available evidence about the effects of clinical care. Such studies may use surveys, medical records, disease registries, and a variety of administrative data sources. Even when a randomized trial has been conducted, observational studies can be used to estimate the real-world effect of an intervention, which may differ from the results obtained in the controlled setting of a clinical trial. This article reviews the goals, methodologies, data sources, and limitations of clinical outcomes research, with a focus on gynecologic oncology.

RESUMO

OBJECTIVE: Surgical cytoreduction has been postulated to affect survival by increasing the efficacy of chemotherapy in ovarian cancer. We hypothesized that women with high-grade serous ovarian cancer, which usually responds to chemotherapy, would derive greater benefit from complete cytoreduction than those with histologic subtypes that are less responsive to chemotherapy, such as mucinous and clear cell carcinoma. METHODS: We conducted a retrospective cohort study of patients who underwent primary cytoreductive surgery and adjuvant chemotherapy for stage IIIC or IV epithelial ovarian cancer from 2011 to 2013 using data from the National Cancer Database. We constructed multivariable models to quantify the magnitude of associations between residual disease status (no residual disease, ≤1cm, or >1cm) and all-cause mortality by histologic type among women with clear cell, mucinous, and high-grade serous ovarian cancer. Because 26% of the sample had unknown residual disease status, we used multiple imputations in the primary analysis. RESULTS: We identified 6,013 women with stage IIIC and IV high-grade serous, 307 with clear cell, and 140 with mucinous histology. The association between residual disease status and mortality hazard did not differ significantly among histologic subtypes of ovarian cancer (p for interaction=0.32). In covariate adjusted models, compared to suboptimal cytoreduction, cytoreduction to no gross disease was associated with a hazard reduction of 42% in high-grade serous carcinoma (hazard ratio [HR]=0.58, 95% confidence interval [CI]=0.49-0.68), 61% in clear cell carcinoma (HR=0.39, 95% CI=0.22-0.69), and 54% in mucinous carcinoma (HR=0.46, 95% CI=0.22-0.99). CONCLUSIONS: We found no evidence that surgical cytoreduction was of greater prognostic importance in high-grade serous carcinomas than in histologies that are less responsive to chemotherapy.

RESUMO

PURPOSE: To examine patterns of care and survival for Hispanic women compared to white and African American women with high-grade endometrial cancer. METHODS: We utilized the National Cancer Data Base (NCDB) to identify women diagnosed with uterine grade 3 endometrioid adenocarcinoma, carcinosarcoma, clear cell carcinoma and papillary serous carcinoma between 2003 and 2011. The effect of treatment on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazards model. RESULTS: 43,950 women were eligible. African American and Hispanic women had higher rates of stage III and IV disease compared to white women (36.5% vs. 36% vs. 33.5%, p<0.001). African American women were less likely to undergo surgical treatment for their cancer (85.2% vs. 89.8% vs. 87.5%, p<0.001) and were more likely to receive chemotherapy (36.8% vs. 32.4% vs. 32%, p<0.001) compared to white and Hispanic women. Over the entire study period, after adjusting for age, time period of diagnosis, region of the country, urban or rural setting, treating facility type, socioeconomic status, education, insurance, comorbidity index, pathologic stage, histology, lymphadenectomy and adjuvant treatment, African American women had lower overall survival compared to white women (Hazard Ratio 1.21, 95% CI 1.16-1.26). Conversely, Hispanic women had improved overall survival compared to white women after controlling for the aforementioned factors (HR 0.87, 95% CI 0.80-0.93). CONCLUSIONS: Among women with high-grade endometrial cancer, African American women have lower all-cause survival while Hispanic women have higher all-cause survival compared to white women after controlling for treatment, sociodemographic, comorbidity and histopathologic variables.

RESUMO

BACKGROUND: Whereas advances in minimally invasive surgery have made laparoscopic staging technically feasible in stage I epithelial ovarian cancer, the practice remains controversial because of an absence of randomized trials and lack of high-quality observational studies demonstrating equivalent outcomes. OBJECTIVE: This study seeks to evaluate the association of laparoscopic staging with survival among women with clinical stage I epithelial ovarian cancer. STUDY DESIGN: We used the National Cancer Data Base to identify all women who underwent surgical staging for clinical stage I epithelial ovarian cancer diagnosed from 2010 through 2012. The exposure of interest was planned surgical approach (laparoscopy vs laparotomy), and the primary outcome was overall survival. The primary analysis was based on an intention to treat: all women whose procedures were initiated laparoscopically were categorized as having had a planned laparoscopic procedure, regardless of subsequent conversion to laparotomy. We used propensity methods to match patients who underwent planned laparoscopic staging with similar patients who underwent planned laparotomy based on observed characteristics. We compared survival among the matched cohorts using the Kaplan-Meier method and Cox regression. We compared the extent of lymphadenectomy using the Wilcoxon rank-sum test. RESULTS: Among 4798 eligible patients, 1112 (23.2%) underwent procedures that were initiated laparoscopically, of which 190 (17%) were converted to laparotomy. Women who underwent planned laparoscopy were more frequently white, privately insured, from wealthier ZIP codes, received care in community cancer centers, and had smaller tumors that were more frequently of serous and less often of mucinous histology than those who underwent staging via planned laparotomy. After propensity score matching, time to death did not differ between patients undergoing planned laparoscopic vs open staging (hazard ratio, 0.77, 95% confidence interval, 0.54-1.09; P = .13). Planned laparoscopic staging was associated with a slightly higher median lymph node count (14 vs 12, P = .005). Planned laparoscopic staging was not associated with time to death after adjustment for receipt of adjuvant chemotherapy, histological type and grade, and pathological stage (hazard ratio, 0.82, 95% confidence interval, 0.57-1.16). CONCLUSION: Surgical staging via planned laparoscopy vs laparotomy was not associated with worse survival in women with apparent stage I epithelial ovarian cancer.

RESUMO

OBJECTIVE: Neoadjuvant chemotherapy and interval debulking surgery for the treatment of advanced ovarian cancer has remained controversial, despite the publication of two randomized trials comparing this modality with primary cytoreductive surgery. This study describes temporal trends in the utilization of neoadjuvant chemotherapy and interval debulking surgery in clinical practice in the United States. METHODS: We completed a time trend analysis of the National Cancer Data Base. We identified women with stage IIIC and IV epithelial ovarian cancer diagnosed between 2004 and 2013. We categorized subjects as having undergone one of four treatment modalities: primary cytoreductive surgery followed by adjuvant chemotherapy, neoadjuvant chemotherapy followed by interval debulking surgery, surgery only, and chemotherapy only. Temporal trends in the frequency of treatment modalities were evaluated using Joinpoint regression, and χ2 tests. RESULTS: We identified 40,694 women meeting inclusion criteria, of whom 27,032 (66.4%) underwent primary cytoreductive surgery and adjuvant chemotherapy, 5429 (13.3%) received neoadjuvant chemotherapy and interval surgery, 5844 (15.4%) had surgery only, and 2389 (5.9%) received chemotherapy only. The proportion of women receiving neoadjuvant chemotherapy and surgery increased from 8.6% to 22.6% between 2004 and 2013 (p<0.001), and adoption of this treatment modality occurred primarily after 2007 (95%CI 2006-2009; p=0.001). During this period, the proportion of women who received primary cytoreductive surgery and chemotherapy declined from 68.1% to 60.8% (p<0.001), and the proportion who underwent surgery only declined from 17.8% to 9.9% (p<0.001). CONCLUSION: Between 2004 and 2013 the frequency of neoadjuvant chemotherapy and interval surgery increased significantly in the United States.

RESUMO

OBJECTIVE: To investigate racial disparities with respect to adjuvant treatment and survival in patients presenting with malignant ovarian germ cell tumors (OGCT). METHODS: The National Cancer Database (NCDB) was used to identify women diagnosed with OGCT. Demographic data were abstracted, including stratification by race and histology. Standard univariate and multivariate analyses using logistic regression were performed to describe predictors of adjuvant treatment. Kaplan-Meier and Cox proportional hazards survival methods were used to evaluate racial differences in survival between African American (AA) and white (W) women. RESULTS: The study population included 2196 patients, with 1654 (75.3%) W and 328 (14.9%) AA women. Histologic distribution varied significantly by race (p<0.0001), but neither age nor stage at presentation showed racial differences (p=0.086 and p=0.209, respectively). AA received more chemotherapy than W (W: 54.6%, AA: 65.5%, p=0.008), but in multivariate analysis there was no statistically significant difference in any adjuvant treatment modality. Despite similar treatment, and independent of histology, survival varied significantly by race with 91% (CI 0.89-0.93) five year survival in W patients compared to 84% five year survival in AA (CI 0.8-0.89) (p=0.02). These disparities were most pronounced in advanced stage disease, with 5 year survival of 84% (CI 0.79-0.89) in W compared to 61% (CI 0.48-0.78) for AA in stage III (p=0.0002), and 54% (CI 0.42-0.68) compared to 14% (CI 0.03-0.71) for stage IV (p=0.05). CONCLUSIONS: AA with OGCT have significantly worse 5 year survival when compared to W patients despite similar rates and modalities of adjuvant treatment.
