RESUMEN
Approximately 10% of patients with malignant ovarian germ cell tumors will experience a tumor relapse. Given the rarity of malignant ovarian germ cell tumors, management of these patients is challenging. Secondary cytoreductive surgery can be considered for carefully selected patients with a goal to achieve complete gross or optimal resection. For patients with platinum sensitive disease who have already received platinum-based chemotherapy, standard dose chemotherapy with paclitaxel/ifosfamide/cisplatin or vinblastine/ifosfamide/cisplatin can be considered. High-dose chemotherapy protocols at specialized centers should be explored even for patients with platinum-resistant disease; however, optimal timing is under investigation. A subset of patients with malignant ovarian germ cell tumors harbors potentially actionable genomic alterations. Further research is required to identify novel therapeutic approaches for these patients.
RESUMEN
Observational and cohort studies using large databases have made important contributions to gynecologic oncology. Knowledge of the advantages and potential limitations of commonly used databases benefits both readers and reviewers. In this review, researchers familiar with National Cancer Database (NCDB), Surveillance, Epidemiology, and End Results Program (SEER), SEER-Medicare, MarketScan, Healthcare Cost and Utilization Project (HCUP), National Surgical Quality Improvement Program (NSQIP), and Premier, describe each database, its included data, access, management, storage, highlights, and limitations. A better understanding of these commonly used datasets can help readers, reviewers, and researchers to more effectively interpret and apply study results, evaluate new research studies, and develop compelling and practice-changing research.
RESUMEN
OBJECTIVE: To investigate the impact of a prior cervical excisional procedure on the oncologic outcomes of patients with apparent early-stage cervical carcinoma undergoing radical hysterectomy. METHODS: The National Cancer Database (2004-2015) was accessed, and patients with FIGO 2009 stage IB1 cervical cancer who had a radical hysterectomy with at least 10 lymph nodes (LNs) removed and a known surgical approach were identified. Patients who did and did not undergo a prior cervical excisional procedure (within 3 months of hysterectomy) were selected for further analysis. Overall survival (OS) was evaluated following the generation of Kaplan-Meier curves and compared with the log-rank test. A Cox model was constructed to control a priori-selected confounders. RESULTS: A total of 3159 patients were identified; 37.1% (n = 1171) had a prior excisional procedure. These patients had lower rates of lymphovascular invasion (29.2% vs. 34.9%, p = 0.014), positive LNs (6.7% vs. 12.7%, p < 0.001), and a tumor size >2 cm (25.7% vs. 56%, p < 0.001). Following stratification by tumor size, the performance of an excisional procedure prior to radical hysterectomy was associated with better OS even after controlling for confounders (aHR: 0.45, 95% CI: 0.30, 0.66). The rate of minimally invasive surgery was higher among patients who had a prior excisional procedure (61.5% vs. 53.2%, p < 0.001). For these patients, performance of minimally invasive radical hysterectomy was not associated with worse OS (aHR: 1.37, 95% CI: 0.66, 2.82). CONCLUSIONS: For patients undergoing radical hysterectomy, preoperative cervical excision may be associated with a survival benefit. For patients who had a prior excisional procedure, minimally invasive radical hysterectomy was not associated with worse overall survival.
RESUMEN
OBJECTIVE: To evaluate the role of systematic lymphadenectomy at the time of interval cytoreductive surgery for patients with advanced-stage epithelial ovarian carcinoma who achieved complete gross resection. METHODS: The National Cancer DataBase was accessed, and patients diagnosed between 2010 and 2015 with advanced-stage ovarian carcinoma who underwent interval cytoreductive surgery and achieved complete gross resection were identified. Patients who did not undergo lymphadenectomy and those who underwent systematic lymphadenectomy (defined as at least 20 lymph nodes removed) were selected for further analysis. Median overall survival was compared with the log-rank test and controlled for a priori selected confounders. RESULTS: A total of 1060 patients were identified. Systematic lymphadenectomy was performed for 125 (11.8%) patients with a median of 29 lymph nodes (range 20-72) removed. Rate of lymph node metastasis was 62.4%. Patients who underwent systematic lymphadenectomy had higher rate of unplanned readmission (8.9% vs 1.6%, p<0.001), and median hospital stay (6 vs 4 days, p<0.001). Median overall survival for patients who did and did not undergo systematic lymphadenectomy was 44.2 and 40.4 months, respectively, p=0.40. After controlling for confounders, performance of systematic lymphadenectomy was not associated with better survival (HR=0.98, 95% CI 0.80 to 1.19). CONCLUSION: Systematic lymphadenectomy is rarely performed at the time of interval cytoreductive surgery and not associated with a survival benefit for patients who achieved complete gross resection.

The success of chimeric antigen receptor T-cell (CAR-T) therapies in the treatment of hematologic malignancies has led to the investigation of their potential in the treatment of solid tumors, including ovarian cancer. While the immunosuppressive microenvironment of ovarian cancer has been a barrier in their implementation, several early phase clinical trials are currently evaluating CAR-T cell therapies targeting mesothelin, folate receptor a, HER2, MUC16, and B7H3. Ongoing challenges include cytokine-associated and "on-target, off-tumor" toxicities, while most common adverse events include cytokine release syndrome, hemophagocytic lymphohistiocytosis/macrophage activation-like syndrome (HLH/MAS), and neurotoxicity. In the present review, we summarize the current status of CAR-T therapy in ovarian cancer and discuss future directions.
RESUMEN
OBJECTIVE: Investigate the prevalence of ERBB2/HER2 gene amplification among patients with gynecologic malignancies. METHODS: The American Association of Cancer Research (AACR) Genomics Evidence of Neoplasia Information Exchange (GENIE) (version 13.1) database was accessed and patients with endometrial, ovarian, and cervical cancer were identified. Patients with available data on the presence of copy-number gene alterations were selected for further analysis. Incidence of ERBB2 amplification following stratification by tumor site and histology was evaluated. Data from the OncoKB database, as provided by cBioPortal, was utilized to determine presence of pathogenic genomic alterations. RESULTS: A total of 6961 patients who met the inclusion criteria were identified: 49.1% with ovarian cancer, 45.2% with endometrial cancer and 5.7% with cervical cancer respectively. Overall incidence of ERBB2 amplification was 3.8%. Highest incidence of ERBB2 amplification was observed among patients with mucinous ovarian (14.4%), uterine serous (13.2%), uterine clear cell (9.4%), and uterine carcinosarcoma (7.9%). ERBB2 amplification was rare among patients with TP53 wild-type endometrioid endometrial cancer (0.4%). High incidence of mutations in genes of the PI3K pathway was observed among patients with ERBB2 amplified tumors. CONCLUSION: ERBB2 amplification is frequently encountered among patients with uterine serous carcinoma, and mucinous ovarian carcinoma. In addition, a high incidence was also observed among those with uterine clear cell carcinoma, and uterine carcinosarcoma. For patients with endometrioid endometrial carcinoma, incidence of ERBB2 amplification is low, especially in the absence of TP53 mutations.

OBJECTIVE: Our objective was to use real-world data to investigate the impact of delayed interval cytoreductive surgery on the survival of patients with advanced stage high-grade ovarian carcinoma. METHODS: We accessed the National Cancer Database and identified patients diagnosed between 2004-2015 with advanced stage high-grade ovarian carcinoma who received neoadjuvant chemotherapy and underwent interval cytoreductive surgery. Based on timing between surgery and chemotherapy administration patients were categorized into standard (9-13.0 weeks) and delayed (13.01-26 weeks) interval cytoreductive surgery groups. Overall survival was compared with the log-rank test and a Cox model was constructed to control for a priori selected confounders. RESULTS: We identified a total of 5051 patients; 2389 (47.3%) and 2662 (52.7%) in the standard and delayed interval cytoreductive surgery groups respectively. There was no difference in complete gross resection rates (53.2% vs 54.5%, p=0.51). Patients in the delayed interval cytoreductive surgery group were less likely to undergo complex surgery (39.3% vs 45.6%, p<0.001) and had lower rates of unplanned re-admission (4.1% vs 2.6%, p=0.003). There was no difference in overall survival between the standard and delayed interval cytoreductive surgery groups, p=0.13 (median 34.3 vs 33.9 months) even after controlling for confounders (hazard ratio (HR) 1.04, 95% confidence intervals (CIs): 0.97, 1.12). There was no difference in overall survival between the two groups for patients with no gross residual (p=0.95; median overall survival 40.08 vs 39.8 months) or gross residual disease (p=0.16; median overall survival 32.89 and 32.16 months). CONCLUSION: For patients with advanced stage ovarian cancer delayed interval cytoreductive surgery may not be associated with worse overall survival.
RESUMEN
The DNA damage response (DDR) results in activation of a series of key target kinases that respond to different DNA damage insults. DDR inhibitors such as PARP inhibitors lead to the accumulation of DNA damage in tumor cells and ultimately apoptosis. However, responses to DDRi monotherapy in the clinic are not durable and resistance ultimately develops. DDRi-DDRi combinations such as PARPi-ATRi, PAPRi-WEE1i and PARPi-AsiDNA can overcome multiple resistance mechanisms to PARP inhibition. In addition, DDRi-DDRi combinations can provide viable treatment options for patients with platinum-resistant disease. In the present chapter we discuss rationale of DDRi-DDRi strategies that capitalize on genomic alterations found in ovarian cancer and other solid tumors and may provide in the near future new treatment options for these patients.

OBJECTIVE: To investigate the use and outcomes of adjuvant chemotherapy for patients with advanced-stage low-grade serous ovarian carcinoma following primary cytoreductive surgery. METHODS: Patients diagnosed between 2010 and 2015 with International Federation of Gynecology and Obstetrics stage II-IV low-grade serous ovarian carcinoma who underwent primary debulking surgery with known residual disease status and had at least 1 month of follow-up were identified in the National Cancer Database. Adjuvant chemotherapy was defined as receipt of chemotherapy within 6 months of surgery. Overall survival was evaluated using the Kaplan-Meier method and compared with the log-rank test. A Cox model was constructed to control for a priori-selected confounders. A systematic review of the literature was also performed. RESULTS: In total, 618 patients with stage II-IV low-grade serous ovarian carcinoma who underwent primary cytoreductive surgery were identified; 501 (81.1%) patients received adjuvant chemotherapy, while 117 (18.9%) patients did not. The median follow-up of the present cohort was 47.97 months. There was no difference in overall survival between patients who did and did not receive adjuvant chemotherapy (p=0.78; 4-year overall survival rates were 77.5% and 76.1%, respectively). After controlling for patient age, medical co-morbidities, disease stage, and residual disease status, administration of adjuvant chemotherapy was not associated with better overall survival (HR=0.87, 95% CI 0.55 to 1.38). Based on data from three retrospective studies, omission of adjuvant chemotherapy following cytoreductive surgery was not associated with worse progression-free survival benefit (HR=1.25, 95% CI 0.80 to 1.95) for patients with stage III-V low-grade serous ovarian carcinoma. CONCLUSIONS: Adjuvant chemotherapy may not be associated with an overall survival benefit for patients with advanced-stage low-grade serous ovarian carcinoma following primary cytoreductive surgery.

OBJECTIVE: To investigate the utilization and outcomes of adjuvant immunotherapy for patients with vulvar melanoma and inguinal lymph node metastases. METHODS: The National Cancer Database was accessed and patients with vulvar melanoma diagnosed between 2004 and 2015 who did not have distant metastases, underwent inguinal lymphadenectomy, had positive lymph nodes, and at least 1 month of follow-up were identified. Administration of immunotherapy was evaluated and clinicopathological characteristics were compared. Median overall survival was compared with the log-rank test. Stratified analysis based on clinical status of lymph nodes was performed. A Cox model was constructed to evaluate survival after controlling for confounders. RESULTS: A total of 300 patients were identified; the rate of immunotherapy use was 25% (75 patients). Patients who received immunotherapy were younger (median 58 vs 70 years, p<0.001); however, the two groups were comparable in terms of clinical lymph node status, rate of positive tumor margins, presence of tumor ulceration, tumor size, Breslow thickness, and performance of comprehensive lymphadenectomy. There was no overall survival difference between patients who did (median 31.08 months) and did not (median 22.77 months) receive immunotherapy (p=0.18). Following stratification by clinical lymph node status, immunotherapy did not improve overall survival of patients with clinically negative (median 35.35 vs 33.22, p=0.75) or positive lymph nodes (median 23.33 vs 16.99, p=0.64). After controlling for confounders, administration of immunotherapy was not associated with better overall survival (HR 0.81, 95% CI 0.57 to 1.14). CONCLUSIONS: In this study approximately one in four patients received adjuvant immunotherapy. Immunotherapy was not associated with improved overall survival.

OBJECTIVE: To investigate the incidence of MAPK/ERK pathway genomic alterations among patients with gynecologic malignancies. METHODS: We accessed the American Association of Cancer Research Genomics Evidence of Neoplasia Information Exchange publicly available dataset (v13.0). Patients with malignant tumors of the ovary, uterus, and cervix were identified. Following stratification by tumor site and histology, we examined the prevalence of MAPK/ERK pathway gene alterations (somatic mutation, and/or structural chromosome alterations). We included the following RAS-MAPK pathway genes known to be implicated in the dysregulation of the pathway; KRAS, NRAS, BRAF, HRAS, MAP2K1, RAF1, PTPN11, NF1, and ARAF. Data from the OncoKB database, as provided by cBioPortal, were utilized to determine pathogenic gene alterations. RESULTS: We identified a total of 10,233 patients with gynecologic malignancies; 48.2% (n = 4937) with ovarian, 45.2% (n = 4621) with uterine and 6.6% (n = 675) with cervical cancer respectively. The overall incidence of MAPK pathway gene alterations was 21%; the most commonly altered gene was KRAS (13%), followed by NF1 (7%), NRAS (1.3%), and BRAF (1.2%). The highest incidence was observed among patients with mucinous ovarian (71%), low-grade serous ovarian (48%), endometrioid ovarian (37%), and endometrioid endometrial carcinoma (34%). CONCLUSIONS: Approximately 1 in 5 patients with a gynecologic tumor harbor a MAPK/ERK pathway genomic alteration. Novel treatment strategies capitalizing on these alterations are warranted.
RESUMEN
OBJECTIVE: Investigate the incidence of homologous recombination DNA damage response (HR-DDR) genomic alterations among patients with uterine sarcoma. METHODS: The American Association for Cancer Research GENIE v13.0 database was accessed and patients with uterine leiomyosarcoma, adenosarcoma, undifferentiated uterine sarcoma, high-grade endometrial stromal sarcoma, low-grade endometrial stromal sarcoma, and endometrial stromal sarcoma not otherwise specified were identified. We determined the incidence of pathogenic alterations in the following genes involved in HR-DDR: ATM, ARID1A, ATRX, BAP1, BARD1, BLM, BRCA2, BRCA1, BRIP1, CHEK2, CHEK1, FANCA, FANCC, FANCD2, FANCE, FANCF, FANCG, FANCL, MRE11, NBN, PALB2, RAD50, RAD51, RAD51B, RAD51C, RAD51D, WRN. Data from the OncoKB database, as provided by cBioPortal, was utilized to determine the presence of pathogenic genomic alterations. RESULTS: A total of 509 patients contributing with 525 samples were identified. Median patient age at sample collection was 56 years while the majority were White (80.7%). The most common histologic subtype was leiomyosarcoma (63.8%) followed by adenosarcoma (12.3%). The overall incidence of HR-DDR genomic alterations was 28.2%. The most commonly altered genes were ATRX (18.2%), BRCA2 (4%), and RAD51B (2.6%). The highest incidence of HR-DDR genomic alterations was observed among patients with leiomyosarcoma (35.4%), adenosarcoma (27%) and undifferentiated uterine sarcoma (30%), while those with low-grade endometrial stromal sarcoma had the lowest (2.9%) incidence. CONCLUSIONS: Approximately 1 in 3 patients with uterine sarcoma harbor a pathogenic alteration in HR-DDR genes. Incidence is high among patients with uterine leiomyosarcoma and adenosarcoma.
RESUMEN
Approximately 10-25% of patients with locally advanced cervical cancer harbor metastases to the para-aortic lymph nodes. Staging of patients with locally advanced cervical cancer can be performed with imaging techniques, such as PET-CT; however, false negative rates can be as high as 20%, especially for patients with pelvic lymph node metastases. Surgical staging can identify patients with microscopic lymph nodes metastases and aid in accurate treatment planning with the administration of extended-field radiation therapy. Data from retrospective studies investigating the impact of para-aortic lymphadenectomy on the oncological outcomes of patients with locally advanced cervical cancer are mixed, while data from randomized controlled trials do not demonstrate a progression-free survival benefit. In the present review, we explore controversies in the staging of patients with locally advanced cervical cancer and summarize the available literature.
RESUMEN
OBJECTIVE: Investigate outcomes for advanced stage epithelial ovarian cancer (EOC) patients based on facility-level utilization of neoadjuvant chemotherapy (NACT). METHODS: Stage III-IV EOC patients diagnosed between 2010 and 2016 were identified in the National Cancer Database. Percentage of patients managed with NACT was calculated for facilities, reporting ≥120 patients. Facilities with lowest and highest quartile of NACT rate comprised the low and high-utilizing groups. Clinico-pathological characteristics were collected, and appropriate statistical analysis performed. RESULTS: High- and low-utilizing facilities managed on average 54.1% and 25.4% of patients with NACT respectively. Patients managed at high-utilizing facilities were significantly more likely to be >65 (p = 0.029), have stage IV disease (p < 0.001) and comorbidities (p < 0.001). Patients managed with primary debulking surgery (PDS) at low-utilizing facilities were significantly more likely to be >65, have stage IV disease, and have comorbidities (all, p < 0.001). Patients undergoing PDS at low-utilizing facilities were significantly less likely to achieve complete gross resection (p < 0.001), and were significantly more likely to experience 90-day mortality (p < 0.001), and unplanned 30-day readmission (p < 0.001). After controlling for age, comorbidities, race, insurance status, stage, grade and histology, high-utilizing facilities trended towards better overall survival (OS) (HR: 0.92, 95% CI: 0.85-0.99). Overall, patients undergoing PDS had better OS compared to those who had NACT (median 42 vs 27 months, p < 0.001). CONCLUSIONS: Despite treating an EOC population with more advanced disease and comorbidities, high-utilizing facilities have lower surgical morbidity and mortality with no detrimental impact on long-term survival. Careful patient selection to minimize the morbidity and mortality associated with PDS is pivotal.

OBJECTIVES: Evaluate whether the addition of external beam radiation (EBRT) to adjuvant chemotherapy with or without vaginal brachytherapy is associated with better survival for patients with stage IIIC endometrioid endometrial carcinoma. MATERIALS AND METHODS: Patients diagnosed between 2010 and 2015 with apparent early-stage endometrioid adenocarcinoma, without a history of another tumor, who underwent hysterectomy with lymphadenectomy and had positive lymph nodes were identified in the National Cancer Database. Those who received adjuvant chemotherapy (defined as receipt of treatment within 6 mo from surgery) and had at least 1 month of follow-up were selected for further analysis. Overall survival was compared between patients who did and did not receive EBRT within 6 months from surgery with the log-rank test. A Cox model was also constructed to control for confounders. RESULTS: A total of 3116 patients were identified; 1458 (46.8%) received chemotherapy without and 1658 (53.2%) with EBRT. Pathologic characteristics (tumor grade, size, endocervical, and lymph-vascular invasion) were comparable between the two groups. Patients who received external beam radiation had better survival compared with those who did not, P =0.001; 5-year overall survival rates were 83.1% and 77.9%, respectively. After controlling for patient age, race, presence of comorbidities, insurance status, tumor size, grade and endocervical invasion, and the presence of lymph-vascular invasion, the addition of EBRT was associated with a survival benefit (HR: 0.75, 95% CI: 0.62, 0.91). CONCLUSIONS: For patients with endometrioid adenocarcinoma metastatic to the lymph nodes, addition of external beam radiation to adjuvant chemotherapy may be associated with a survival benefit.

RESUMEN
OBJECTIVE: To investigate the utilization and outcomes of ovarian preservation for premenopausal patients with International Federation of Gynecology and Obstetrics (FIGO) stage I grade 2 and 3 endometrioid endometrial carcinoma undergoing hysterectomy. METHODS: The National Cancer Database was accessed; patients aged ≤45 years diagnosed between January 2004 and December 2015 with FIGO stage I grade 2 or 3 endometrioid endometrial carcinoma, who underwent hysterectomy with or without bilateral salpingo-oophorectomy and had at least 1 month of follow-up, were identified. Overall survival was assessed following generation of Kaplan-Meier curves and compared with the log-rank test. A Cox model was constructed to control for a priori selected variables. RESULTS: A total of 2941 patients who met the inclusion criteria were identified; 200 (6.8%) patients did not undergo bilateral salpingo-oophorectomy. Rate of ovarian preservation was comparable between patients with grade 2 (n=163, 6.6%) and grade 3 (n=37, 7.7%) tumors (p=0.38). Patients who did not undergo bilateral salpingo-oophorectomy were younger (median 39 vs 41 years, p<0.001) and less likely to undergo surgical lymph node assessment (52% vs 76.2%, p<0.001). There was no difference in overall survival between patients who did and did not undergo bilateral salpingo-oophorectomy (p=0.94); 5 year overall survival rates were 96.6% and 97%, respectively. After controlling for confounders, including tumor grade, ovarian preservation was not associated with worse overall survival (HR 0.92, 95% CI 0.47 to 1.84). CONCLUSIONS: For patients with grade 2 and 3 FIGO stage I endometrioid carcinoma undergoing hysterectomy, ovarian preservation is rarely performed while no clear detrimental effect on overall survival was found.
RESUMEN
OBJECTIVES: We aimed to evaluate the utilization and impact of surgical para-aortic lymph node staging on the survival of patients with locally advanced stage cervical carcinoma receiving definitive chemoradiation. METHODS: We identified patients in the National Cancer Database diagnosed between January 2010 and December 2015 with locally advanced (FIGO 2009 stage IB2-IVA) cervical carcinoma who did not undergo hysterectomy, received primary chemoradiation and had at least 1 month of follow-up. Two groups of patients were formed based on the assessment method of para-aortic lymph node status - radiologic assessment only versus surgical lymphadenectomy. Overall survival was compared with the log-rank test after Kaplan-Meier curves were generated. A Cox model was constructed to control for a priori selected confounders. RESULTS: We identified a total of 3540 patients who met the inclusion criteria. Para-aortic staging was performed in 333 (9.4%) patients. These patients were younger (median age 46 vs 52 years, p<0.001), less likely to have co-morbidities (8.7% vs 15.6%, p<0.001), more likely to have private insurance (48.9% vs 37.8%, p<0.001) and receive brachytherapy (76.9% vs 70.9%, p=0.022). The rate of para-aortic lymphadenectomy was comparable between patients with stage IB2-II and III-IVA disease (9.4% for both groups, p=0.98). Patients who underwent para-aortic lymphadenectomy were also more likely to have lymph nodes categorized as positive compared with those who had imaging only (27.3% vs 13.2%, p<0.001). There was no difference in overall survival between patients who underwent radiologic only or surgical para-aortic lymph node assessment (p=0.80 from log-rank test); 4 year overall survival rates were 62.9% and 63%. After controlling for confounders, performance of para-aortic lymphadenectomy was not associated with a survival benefit (HR 1.07, 95% CIs: 0.88 to 1.31). CONCLUSIONS: In a large cohort of patients with locally advanced stage cervical carcinoma, para-aortic lymphadenectomy was rarely performed and not associated with a survival benefit.

OBJECTIVE: The goal of this study was to evaluate if addition of adjuvant chemotherapy to radiation therapy improves overall survival in patients with high-intermediate risk stage I endometrial carcinoma with lymphovascular invasion. METHODS: Patients diagnosed between January 2010 and December 2015 with FIGO (International Federation of Gynecology and Obstetrics) stage I endometrioid endometrial carcinoma with lymphovascular invasion who underwent hysterectomy with lymphadenectomy and met the GOG-99 criteria for high-intermediate risk were identified in the National Cancer Database. Patients who received adjuvant radiotherapy with or without adjuvant chemotherapy (administered within 6 months of surgery) and had at least 1 month of follow-up were selected for further analysis. Overall survival was compared with the log-rank test following stratification by type of radiation treatment. A Cox model was constructed to control for a priori selected confounders. RESULTS: A total of 2881 patients who met the inclusion criteria were identified; 2417 (83.9%) patients received radiation therapy alone while 464 (16.1%) received chemoradiation. Rate of adjuvant chemotherapy administration was comparable between patients who received vaginal brachytherapy alone (16.2%), and external beam radiation therapy (with or without vaginal brachytherapy) (15.8%), p=0.78. Rate of chemoradiation was higher for patients with grade 3 (28.8%) tumors compared with those with grade 2 (9.9%) and grade 1 (8.3%) tumors, p<0.001. After controlling for confounders for patients receiving external beam radiation, addition of chemotherapy was not associated with improved overall survival (HR 0.90, 95% CI 0.56 to 1.46). For patients receiving vaginal brachytherapy addition of chemotherapy was associated with better overall survival (HR 0.644, 95% CI 0.45 to 0.92). Benefit was limited to patients with grade 3 tumors, p=0.026; 4-year overall survival rate was 81.1% versus 74.9%. CONCLUSIONS: In patients with high-intermediate risk FIGO stage I endometrioid endometrial carcinoma and lymphovascular invasion, addition of chemotherapy to radiation therapy was associated with a survival benefit for patients with grade 3 tumors receiving vaginal brachytherapy.
