Abstract
Introduction There is limited data on endometrial cancer from developing countries. The risk groups as defined by the ESMO-ESGO-ESTRO and their recommendations for adjuvant treatment have redefined the management protocols. In this retrospective analysis, the outcomes are assessed in the light of the new risk groups and FIGO staging. Material Methods One hundred and two patients of endometrial cancer reporting to the Department of Radiation Oncology from 2015 to 2019 were analysed retrospectively. Patients were stratified as per the ESMO-ESGO-ESTRO risk groups and FIGO staging. Patients were analysed for demographic profile, histopathology details, FIGO stage, treatment modalities received as per the ESMO-ESGO-ESTRO risk groups and the outcomes in terms of disease free survival and overall survival. Results A total of 102 patients were analysed. The mean age at presentation was 57.7 years. Seventy four percent (74.41%) were stage I patients, 14.7 % were stage II, 8.8% were stage III and remaining 2% were stage IV. The mean disease free survival for the patients in FIGO stage I, II, III and IV were found to be 63.5 (59.9 - 67) months, 60.5 (54.2 - 66.9) months, 30.9 (21.5 - 40.2) months and 15.4 (7.8 - 23.0) months respectively. The 5-year overall survival of patients in Stage I was 90.3%. The 3-year mortality of Stage III patients was 58.3%. While there was no mortality observed among Stage II patients, none of the Stage IV patient survived beyond 20 months. The 5-year disease-free survival for patients in Low Risk (LR) group, Intermediate Risk (IR) group and High Risk (HR) group was found to be 91.3%, 90% and 87% respectively. None of the patient in High Intermediate Risk (HIR) group experienced progression of disease and 33.3% patients in advanced group were disease free at 2 years follow-up. The multivariate analysis showed that lymph node involvement is significantly associated with disease-free (p=0.03) and overall survival (p=0.04). Conclusion Even in the developing world, majority of patients present in early stage with survival outcomes comparable to the West. FIGO stage and lymph node involvement continue to be the most important prognostic markers for disease outcomes.

Abstract
Purpose Upfront radiation therapy consisting of brachytherapy with or without external beam radiation therapy is considered standard of care for patients with endometrial carcinoma who are unable to undergo surgical intervention. This study evaluated the cancer-free survival (CFS), cancer-specific survival (CSS), and overall survival (OS) of patients with endometrial carcinoma managed with definitive-intent radiation therapy. Methods and Materials This was a single-institution retrospective analysis of medically inoperable patients with biopsy-proven endometrial carcinoma managed with up-front, definitive radiation therapy at UMass Memorial Medical Center between May 2010 and October 2021. A total of 55 cases were included for analysis. Patients were stratified as having low-risk endometrial carcinoma (LREC; uterine-confined grade 1-2 endometrioid adenocarcinoma) or high-risk endometrial carcinoma (HREC; stage III/IV and/or grade 3 endometrioid carcinoma, or any stage serous or clear cell carcinoma or carcinosarcoma). The CFS, CSS, OS, and grade ≥3 toxic effects were reported for patients with LREC and HREC. Results The median age was 66 years (range, 42-86 years), and the median follow-up was 44 months (range, 4-135 months). Twelve patients (22%) were diagnosed with HREC. Six patients (11%) were treated with high-dose-rate brachytherapy alone and 49 patients (89%) were treated with high-dose-rate brachytherapy and external beam radiation therapy. Twelve patients (22%) were treated with radiation and chemotherapy. The 2-year CFS was 82% for patients with LREC and 80% for patients with HREC (log rank P = .0654). The 2-year CSS was 100% for both LREC and HREC patients. The 2-year OS was 92% for LREC and 80% for HREC (log P = .0064). There were no acute grade ≥3 toxic effects. There were 3 late grade ≥3 toxic effects owing to endometrial bleeding and gastrointestinal adverse effects. Conclusions For medically inoperable patients with endometrial carcinoma, up-front radiation therapy provided excellent CFS, CSS, and OS. The CSS and OS were higher in patients with LREC than in those with HREC. Toxic effects were limited in both cohorts.

Abstract
Adjuvant therapy recommendations for endometrial cancer were historically based on the individual patient's risk of disease recurrence using clinicopathologic factors such as age, stage, histologic subtype, tumor grade, and lymphovascular space invasion. Despite the excellent prognosis for early stages, considerable under- and overtreatment remains. Integrated genomic characterization by the Cancer Genome Atlas (TCGA) in 2013 defined four distinct endometrial cancer subgroups (POLE mutated, microsatellite instability, low copy number, and high copy number) with possible prognostic value. The validation of surrogate markers (p53, Mismatch repair deficiency, and POLE) to determine these subgroups and the addition of other molecular prognosticators (CTNNB1, L1CAM) resulted in a practical and clinically useful molecular classification tool. The incorporation of such molecular alterations into established clinicopathologic risk factors resulted in a refined, improved risk assessment. Thus, the ESGO/ESTRO/ESP consensus in 2020 defined for the first time different prognostic risk groups integrating molecular markers. Finally, the feasibility and clinical utility of molecular profiling for tailoring adjuvant therapy in the high-intermediate-risk group is currently under investigation (NCT03469674).

Abstract
Endometrioid endometrial adenocarcinoma (EEC) is the most common malignancy of the female genital tract. According to the 2009 FIGO staging system, the depth of myometrial invasion (MI), and tumor spread to adjacent organs or tissues are the staging criteria for endometrial carcinoma (EC). Therefore, assessment of the depth of MI is of great importance. There is a spectrum of morphological patterns of MI. Still, their number and features vary according to the scientific literature, with a certain overlap that creates difficulties and controversies in the precise assessment of MI depth. The purpose of this review is to present and discuss the most important and recent information about patterns of MI, focusing on the more aggressive and the elongated and fragmented glands (MELF) pattern in particular. Assessment of MI depth and correct staging of EC is possible only after the precise recognition of each MI pattern.

Abstract
OBJECTIVES Patients with early-stage endometrial cancers (EC) with disease recurrences have worse survival outcomes. The purpose of this study was to identify clinical and pathologic factors that predict for all recurrences in stage IA grade 1 (IAG1) EC. METHODS Records from patients diagnosed with EC were retrospectively reviewed. Baseline characteristics of 222 patients with IAG1 EC who underwent surgical resection were analyzed. Cox proportional hazard analysis was used to identify univariate and multivariate risk factors that predict for recurrence. RESULTS Seventeen (7.65%) patients had recurrences. The 3-year cumulative incidence of recurrence were significantly higher for patients with time from biopsy to surgery ≥6 months (54% vs. 8%, p=0.003), simple hysterectomy with ovarian preservation vs. total hysterectomy and bilateral salpingo-oophorectomy (31% vs. 9%, p=0.032), any myometrial invasion vs. no invasion (18% vs. 2%, p=0.004), and tumor size ≥2 cm (15% vs. 2%, p=0.021). On, multivariate analysis, any myometrial invasion, increasing time from biopsy to surgery, and larger tumor size were independent predictors of any recurrence. Patients with recurrences had worse outcomes than those without (5-year overall survival [OS]=60%; 95% confidence interval [CI]=16%-86% vs. 5-year OS=95%; 95% CI=87%-99%, respectively, p=0.003). CONCLUSION Time from biopsy to surgery, larger tumors, and myometrial invasion are the most important predictors of recurrence. Though the recurrence rates are generally low in IAG1 EC, the survival rate for the patients with recurrences was worse than those without. Identification of additional recurrence risk factors can help select patients who may benefit from adjuvant treatment.

Abstract
Gynecologic malignancies are among the most prevalent cancers affecting women worldwide, but they are heterogeneous diseases with varying risk factors, management paradigms, and outcomes. Gynecologic cancers mediated by human papillomavirus (HPV) are preventable and curable with early detection and treatment. Dramatic reductions in cervical cancer incidence and mortality have been achieved through cancer screening and HPV vaccination. Radiotherapy plays a central role in the management of gynecologic malignancies. For some cancers, radiotherapy alone can be curative. More often, radiotherapy is used in conjunction with surgery and systemic therapy to improve locoregional control and extend overall survival. This chapter reviews recent advances in radiotherapeutic management of gynecologic malignancies.

Abstract
OBJECTIVE Adjuvant management of women with high-intermediate- and high-risk early-stage endometrial cancer remains controversial. Recently published results of GOG 249 revealed that vaginal brachytherapy plus chemotherapy (VBT + CT) was not superior to whole pelvic radiation therapy (WPRT) and was associated with more toxicities and higher nodal recurrences. This study examined off-study utilization of VBT + CT among women who met criteria for GOG 249 in the period prior to study publication. METHODS Women diagnosed with FIGO IA-IIB endometrioid, serous, or clear cell uterine cancer between 2004-2015 and treated with hysterectomy and radiotherapy (RT) were identified in the National Cancer Database. Cochrane-Armitrage trend test was used to assess trends over time. Univariate and multivariate Cox analyses were performed to calculate odds ratio (OR) of VBT + CT receipt and hazard ratio (HR) of OS. Propensity-score matched analysis was conducted to account for baseline differences. RESULTS 9956 women met inclusion criteria. 7548 women (75.8%) received WPRT while 2408 (24.2%) received VBT + CT in the study period. From 2004-2015, there was a significant increase in VBT + CT use (p < 0.001) with the largest overall increase occurring in 2009 to 22%. Factors significantly associated with VBT + CT receipt included higher socioeconomic status (p < 0.001), higher grade endometrioid cancer (p < 0.001), and aggressive histology (p < 0.001). After propensity-score matching, VBT + CT was associated with improved OS (HR 0.74, 95% CI 0.58-0.93); however, when stratified by FIGO stage, VBT + CT was only associated with improved OS for FIGO stage 1B (HR 0.62, 95% CI 0.44-0.87). CONCLUSIONS There was significant use of experimental arm off-study treatment in the United States prior to report of GOG 249 results. Providers should be cautious when offering off-study treatment utilizing an experimental regimen given uncertainty about efficacy and toxicity.

Using the Radiosensitivity Index (RSI) to Predict Pelvic Failure in Endometrial Cancer Treated With Adjuvant Radiation Therapy. Int J Radiat Oncol Biol Phys 2019; 106:496-502. [PMID: 31759077 DOI: 10.1016/j.ijrobp.2019.11.013] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2019] [Revised: 10/20/2019] [Accepted: 11/06/2019] [Indexed: 12/24/2022]
Abstract
PURPOSE Variability exists in the adjuvant treatment for endometrial cancer (EC) based on surgical pathology and institutional preference. The radiosensitivity index (RSI) is a previously validated multigene expression index that estimates tumor radiosensitivity. We evaluate RSI as a genomic predictor for pelvic failure (PF) in EC patients treated with adjuvant radiation therapy (RT). METHODS AND MATERIALS Using our institutional tissue biorepository, we identified EC patients treated between January 1999 and April 2011 with primarily endometrioid histology (n = 176; 86%) who received various adjuvant therapies. The RSI 10-gene signature was calculated for each sample using the previously published algorithm. Radiophenotype was determined using the previously identified cutpoint where RSI ≥ 0.375 denotes radioresistance (RR) and RSI < 0.375 describes radiosensitivity. RESULTS A total of 204 patients were identified, of which 83 (41%) were treated with adjuvant RT. Median follow-up was 38.5 months. All patients underwent hysterectomy with bilateral salpingo-oophorectomy with the majority undergoing lymph node dissection (n = 181; 88%). In patients treated with radiation, RR tumors were more likely to experience PF (3-year pelvic control 84% vs 100%; P = .02) with worse PF-free survival (PFFS) (3-year PFFS 65% vs 89%; P = .04). Furthermore, in the patients who did not receive RT, there was no difference in PF (P = .87) or PFFS (P = .57) between the RR/radiosensitive tumors. On multivariable analysis, factors that continued to predict for PF included the RR phenotype (hazard ratio [HR], 12.2; P = .003), lymph node involvement (HR, 4.4; P = .02), and serosal or adnexal involvement (HR, 5.3; P = .01). CONCLUSIONS On multivariable analysis, RSI was found to be a significant predictor of PF in patients treated with adjuvant RT. We propose using RSI to predict which patients are at higher risk for failing in the pelvis and may be candidates for treatment escalation in the adjuvant setting.

Abstract
OBJECTIVES To compare patterns of care and overall survival (OS) between stereotactic body radiotherapy (SBRT) and percutaneous local tumor ablation (LTA) for non-surgically managed early-stage non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS The National Cancer Database (NCDB) was queried from 2004 to 2014 for adults with non-metastatic, node-negative invasive adenocarcinoma or squamous cell carcinoma of the lung with primary tumor size ≤5.0 cm who did not undergo surgery or chemotherapy and received SBRT or LTA. Patterns of care were assessed with multivariate logistic regression. After propensity-score weighting with generalized boosted regression, OS was assessed with univariate and doubly-robust multivariate Cox regression. RESULTS Of 15,792 patients, 14,651 (93%) received SBRT and 1141 (7%) received LTA. Increasing age (OR 1.01, p = .035), treatment at an academic institution (OR 2.94, p < .001), increasing tumor size (OR 1.05, p < .001), and more recent year of diagnosis (OR 1.43, p < .001) were predictive of treatment with SBRT, whereas comorbidities (OR 0.74, p = .003) and treatment at a high-volume facility (OR 0.05, p < .001) were predictive for LTA. At a median follow-up of 26.2 months, SBRT was associated with improved OS relative to LTA within a propensity-score weighted doubly-robust multivariate analysis (HR 0.71, p < .001). On weighted subgroup analyses, improved OS was observed with SBRT for tumor sizes >2.0 cm (HR 0.72, p < .001) and for those treated at high-volume facilities (HR 0.71, p < .001). No OS difference was found with SBRT or LTA in tumor sizes ≤2.0 cm (HR 0.90, p = .227). CONCLUSION Within the NCDB, SBRT was more commonly utilized and was associated with improved OS when compared to percutaneous LTA for patients with non-surgically managed early-stage NSCLC. Patients with small tumor volumes likely represent an appropriate population for future prospective randomized comparisons between SBRT and LTA.

Abstract
BACKGROUND Adjuvant chemotherapy treatment for different endometrial cancer stages is still debated. We aimed to evaluate the outcome of early (FIGO I-II) vs late stage (FIGO III-IV) endometrial cancer in an institutional experience using chemotherapy only after surgery. METHOD Charts of patients with endometrial carcinoma who underwent surgery with postoperative chemotherapy between February 2012 and December 2017 were retrospectively identified, and the recurrence as well as prognosis were assessed. RESULT Of the 272 eligible endometrioid adenocarcinoma (EA) patients, 127 had received chemotherapy, 145 did not receive chemotherapy; 37 were in late stage (FIGO III-IV) and 235 were in early stage (FIGO I-II). In the late stage group, patients with no chemotherapy had worse overall survival (OS) and recurrence-free survival (RFS) as compared to the patients taking chemotherapy (OS, 28.6% vs 76.4%, P = 0.059; RFS, 17.1% vs 66.4%, P = 0.053). However, in the early stage group, there was no significant difference between the OS and RFS between the patients that were receiving and not receiving chemotherapy (OS, 84.1% vs 93.3%, P = 0.789; RFS, 76.7% vs 72.4%, P = 0.924). Independent predictive factors of recurrence were age over 53 years, histological grade G3, as well as late stages (FIGO III-IV), while independent predictive factors of OS were age over 53 years, deeper depth of myometrial invasion, and late stages (FIGO III-IV). CONCLUSION In late stages, patients with chemotherapy had lower recurrence rate and favorable OS as compared to patients not taking chemotherapy, which was the benefit of postoperative adjuvant chemotherapy, and chemotherapy might be strongly considered in late stage EA.

Location of recurrences in high-risk stage Iendometrial cancer patients not given postoperative radiotherapy: A Danish gynecological cancer group study. Int J Gynecol Cancer 2019; 29:497-504. [PMID: 30833438 DOI: 10.1136/ijgc-2018-000056] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2018] [Revised: 10/17/2018] [Accepted: 10/19/2018] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVES To study recurrence rates in Danish high-risk stage I endometrial cancers not given radiotherapy in accordance with the decision of the Danish Gynecological Cancer Group. METHODS This prospective national cohort study includes all 4707 endometrial carcinomas diagnosed from 2005 to 2012. Of these, 623 patients had grade 3 endometroid adenocarcinoma with >50% myometrial invasion or serous/clear/undifferentiated carcinoma (with any depth of invasion). In 305 patients with high-risk stage I on final pathology, 14.1% received adjuvant external beam radiotherapy and 9.6% adjuvant chemotherapy. No patients received brachytherapy. 5-year Kaplan-Meier survival estimates and actuarial recurrence rates were calculated, and adjusted Cox regression analysis used for comparison. Recurrence rates were compared with historical Danish population data (DEMCA 98-99). RESULTS For non-irradiated patients, 5-year overall survival, cancer-specific survival, and progression-free survival rates in high-risk stage I patients were 65%, 78%, and 73%, respectively. For non-irradiated patients, isolated local recurrences were uncommon (vaginal 3.1%, pelvic 0.4%). Death was mainly due to a high occurrence of non-local recurrences, with 8.8% experiencing a first recurrence in the abdominal cavity (outside the field where radiation traditionally have been given) and 13.0% a distant metastasis outside the abdominal cavity. Grade 3 tumors with >50% myometrial invasion seem to be characterized by a different pattern of recurrences, with significantly more isolated vaginal recurrences (7.9% vs 2.2%) and fewer total number of abdominal recurrences (7.9% vs 15.3%) as compared with unfavorable tumor types. CONCLUSION Isolated vaginal and pelvic recurrences were rare (3-5%) in patients with a final pathologic diagnosis of high-risk stage I endometrial cancer even after the Danish Gynecological Cancer Group decided to omit all types of postoperative radiotherapy and introduce lymph node staging.

Abstract
PURPOSE To compare radiation toxicity in endometrial cancer patients treated with adjuvant vaginal brachytherapy (VBT) vs. VBT with concurrent chemotherapy (CCT) or sequential chemotherapy (SCT) METHODS: We retrospectively analyzed 131 patients with endometrial cancer treated with VBT without external beam radiation therapy. Toxicities were graded according to the Common Terminology Criteria for Adverse Events v4.03. CCT was defined as VBT delivered between the first and last cycle of chemotherapy (CT); SCT was defined as VBT delivered before or after CT. RESULTS Median followup was 36 months, with a 3-year survival rate of 88%. Of the 131 patients, 92 were treated with VBT alone, 34 with VBT and CCT, and 5 with VBT and SCT. The most common toxicity was vaginal stricture, with 30 (22.9%) patients affected. The distribution of toxicities was vaginal 28%, urinary 12%, rectal 11%, and fatigue 5%; none greater than Grade 2. Compared with patients treated with VBT alone, the addition of CT did not increase the chance of vaginal stricture formation (p = 0.84). The difference in system-specific toxicities between treatment modalities was not statistically significant. CONCLUSION The most common pelvic toxicity from VBT is vaginal stenosis with other toxicities being infrequent and generally Grade 1. The addition of CT in a sequential or concurrent fashion did not increase the rate of pelvic toxicity from VBT alone.

Abstract
OBJECTIVE Radiotherapy (RT) is an established adjuvant treatment for stage II endometrioid endometrial carcinoma (EEC). The role of chemotherapy (CT) in stage II EEC is less proven. We used the National Cancer Data Base to identify factors associated with adjuvant CT in stage II EEC and to explore whether receipt of CT was associated with improved overall survival (OS). METHODS/MATERIALS Women diagnosed in 2010 to 2013 with International Federation of Obstetrics and Gynecology stage II EEC (grades 1-3) after hysterectomy and bilateral salpingo-oophorectomy were identified in the National Cancer Data Base. Multivariable logistic regression was used to identify covariates associated with receipt of CT. Overall survival among patients receiving RT, CT, or chemoradiotherapy (CRT) after surgery was compared using Kaplan-Meier estimates, the log-rank test, Cox proportional hazards regression, and propensity score matching. RESULTS We identified 6102 stage II EEC patients. There were 358 patients (6%) who received adjuvant CT alone and 525 (9%) who received CRT; the remainder received RT alone (n = 1906; 31%) or no adjuvant treatment (n = 3313; 54%). The presence of lymphovascular invasion (odds ratio, 3.58; P < 0.001) and grade 3 disease (odds ratio, 3.40; P < 0.001) was strongly associated with receipt of CT or CRT. The OS at 3 years for the entire cohort was 89%. On multivariable analysis, CT versus RT was associated with worse OS (hazard ratio [HR], 2.12 [95% confidence interval, 1.46-3.06]; P < 0.001), whereas CRT versus RT was not associated with improved OS (HR, 1.07 [95% confidence interval, 0.71-1.62]; P = 0.781). After propensity score matching, there remained no difference in OS between RT and CRT (HR, 1.14; P = 0.614). CONCLUSIONS Patients with stage II EEC have an excellent prognosis, and most undergo observation or receive adjuvant RT in the United States. Receipt of CT (alone or with RT) was not associated with an OS advantage compared with RT alone in this observational cohort. Randomized trials will help clarify the role of CT in stage II patients.

Abstract
Endometrial cancer is a clinically heterogeneous disease and it is becoming increasingly clear that this heterogeneity may be a function of the diversity of the underlying molecular alterations. Recent large-scale genomic studies have revealed that endometrial cancer can be divided into at least four distinct molecular subtypes, with well-described underlying genomic aberrations. These subtypes can be reliably delineated and carry significant prognostic as well as predictive information; embracing and incorporating them into clinical practice is thus attractive. The road towards the integration of molecular features into current classification systems is not without obstacles. Collaborative studies engaging research teams from across the world are working to define pragmatic assays, improve risk stratification systems by combining molecular features and traditional clinicopathological parameters, and determine how molecular classification can be optimally utilized to direct patient care. Pathologists and clinicians caring for women with endometrial cancer need to engage with and understand the possibilities and limitations of this new approach, because integration of molecular classification of endometrial cancers is anticipated to become an essential part of gynaecological pathology practice. This review will describe the challenges in current systems of endometrial carcinoma classification, the evolution of new molecular technologies that define prognostically distinct molecular subtypes, and potential applications of molecular classification as a step towards precision medicine and refining care for individuals with the most common gynaecological cancer in the developed world.

Adjuvant chemoradiotherapy versus radiotherapy alone for women with high-risk endometrial cancer (PORTEC-3): final results of an international, open-label, multicentre, randomised, phase 3 trial. Lancet Oncol 2018; 19:295-309. [PMID: 29449189 PMCID: PMC5840256 DOI: 10.1016/s1470-2045(18)30079-2] [Citation(s) in RCA: 371] [Impact Index Per Article: 61.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2017] [Revised: 11/24/2017] [Accepted: 11/30/2017] [Indexed: 12/14/2022]
Abstract
Background Although women with endometrial cancer generally have a favourable prognosis, those with high-risk disease features are at increased risk of recurrence. The PORTEC-3 trial was initiated to investigate the benefit of adjuvant chemotherapy during and after radiotherapy (chemoradiotherapy) versus pelvic radiotherapy alone for women with high-risk endometrial cancer. Methods PORTEC-3 was an open-label, international, randomised, phase 3 trial involving 103 centres in six clinical trials collaborating in the Gynaecological Cancer Intergroup. Eligible women had high-risk endometrial cancer with FIGO 2009 stage I, endometrioid-type grade 3 with deep myometrial invasion or lymph-vascular space invasion (or both), endometrioid-type stage II or III, or stage I to III with serous or clear cell histology. Women were randomly assigned (1:1) to receive radiotherapy alone (48·6 Gy in 1·8 Gy fractions given on 5 days per week) or radiotherapy and chemotherapy (consisting of two cycles of cisplatin 50 mg/m2 given during radiotherapy, followed by four cycles of carboplatin AUC5 and paclitaxel 175 mg/m2) using a biased-coin minimisation procedure with stratification for participating centre, lymphadenectomy, stage of cancer, and histological type. The co-primary endpoints were overall survival and failure-free survival. We used the Kaplan-Meier method, log-rank test, and Cox regression analysis for final analysis by intention to treat and adjusted for stratification factors. The study was closed on Dec 20, 2013, after achieving complete accrual; follow-up is ongoing. PORTEC-3 is registered with ISRCTN, number ISRCTN14387080, and ClinicalTrials.gov, number NCT00411138. Results 686 women were enrolled between Nov 23, 2006, and Dec 20, 2013. 660 eligible patients were included in the final analysis, of whom 330 were assigned to chemoradiotherapy and 330 were assigned to radiotherapy. Median follow-up was 60·2 months (IQR 48·1–73·1). 5-year overall survival was 81·8% (95% CI 77·5–86·2) with chemoradiotherapy versus 76·7% (72·1–81·6) with radiotherapy (adjusted hazard ratio [HR] 0·76, 95% CI 0·54–1·06; p=0·11); 5-year failure-free survival was 75·5% (95% CI 70·3–79·9) versus 68·6% (63·1–73·4; HR 0·71, 95% CI 0·53–0·95; p=0·022). Grade 3 or worse adverse events during treatment occurred in 198 (60%) of 330 who received chemoradiotherapy versus 41 (12%) of 330 patients who received radiotherapy (p<0·0001). Neuropathy (grade 2 or worse) persisted significantly more often after chemoradiotherapy than after radiotherapy (20 [8%] women vs one [1%] at 3 years; p<0·0001). Most deaths were due to endometrial cancer; in four patients (two in each group), the cause of death was uncertain. One death in the radiotherapy group was due to either disease progression or late treatment complications; three deaths (two in the chemoradiotherapy group and one in the radiotherapy group) were due to either intercurrent disease or late treatment-related toxicity. Interpretation Adjuvant chemotherapy given during and after radiotherapy for high-risk endometrial cancer did not improve 5-year overall survival, although it did increase failure-free survival. Women with high-risk endometrial cancer should be individually counselled about this combined treatment. Continued follow-up is needed to evaluate long-term survival.

Improved Outcome of High-Grade, Early 1-Stage Endometrioid Endometrial Carcinoma With Adjuvant Chemotherapy and Radiotherapy: Comparison of 2 Treatment Strategies.

Abstract
OBJECTIVE Patients with high-grade endometrioid endometrial carcinoma have a high risk of recurrence, even in early stage. To determine the benefit of a more aggressive adjuvant treatment approach, different treatment strategies of 2 referral centers were compared. MATERIALS AND METHODS Outcome of all patients with International Federation of Gynecology and Obstetrics IB and II high-grade endometrioid endometrial carcinoma treated between 2008 and 2012, at the Gynecological Oncology Center South (GOCS) were compared with patients treated at the British Columbia Cancer Agency (BCCA). All patients underwent primary surgical treatment. Adjuvant treatment consisted of radiotherapy dependent on final pathology (GOCS), or adjuvant chemotherapy and pelvic radiotherapy (BCCA). RESULTS A total of 116 patients were treated at the GOCS (n = 61) and BCCA (n = 55). Patient cohorts were comparable for clinicopathological factors, except for age at diagnosis and lymphadenectomy. Radiotherapy was applied in 70.5% at the GOCS compared with 100% at the BCCA. All BCCA patients received chemotherapy compared with 3.3% at GOCS. The BCCA treatment strategy resulted in a significant reduced recurrence rate when compared with GOCS, 10.9% and 36.1%, respectively. There was no significant difference in the recurrence rate between patients with (n = 48) and without a lymphadenectomy (n = 68). Yet, numbers are relatively low. Because most recurrences were distant 78.6% (22/28), adjuvant chemotherapy resulted in reduced disease-related mortality. CONCLUSIONS Adjuvant chemotherapy and radiotherapy in early-stage high-grade endometrioid endometrial carcinoma results in improved disease-specific and overall survival compared to radiotherapy alone. Yet, due to the relatively low numbers, validation of these findings is needed in large prospective trials.

Abstract
Objective To date, there is no convincing evidence comparing the impact of combined chemotherapy and radiotherapy with chemotherapy alone in postoperative uterine serous carcinoma (USC), which remains an unclear issue. We conducted a meta-analysis assessing the impact of combined chemotherapy and radiotherapy compared to chemotherapy alone on overall survival in postoperative USC. Methods A comprehensive search was performed in the databases of EMBASE, PubMed, Web of Science, and Cochrane Library from inception to March 2016. Studies comparing survival among patients who underwent combined chemotherapy and radiotherapy or chemotherapy alone after surgery for USC were included. Quality assessments were carried out by the Newcastle–Ottawa Scale. Hazard ratio (HR) for overall survival was extracted, and a random-effects model was used for pooled analysis. Publication bias was assessed using both funnel plot and the Egger regression test. Statistical analyses were performed using Stata version 13.0 software. Result Nine retrospective studies with relatively high quality containing 9354 patients were included for the final meta-analysis. The pooled results demonstrated that combined chemotherapy and radiotherapy significantly reduced the risk of death (HR, 0.72; P < 0.0001) compared to chemotherapy alone with a low heterogeneity (I2 = 21.0%, P = 0.256). Subgroup analyses indicated that calculating HR by unadjusted method may cause the heterogeneity among studies. Exploratory analyses showed that either patients with early stage disease (HR, 0.73; P = 0.011) or advanced stage disease (HR, 0.80; P < 0.0001) have survival benefits from combined chemotherapy and radiotherapy. No significant evidence of publication bias was found. Conclusions This is the first meta-analysis examining the role of combined chemotherapy and radiotherapy compared to chemotherapy alone in USC. Our results suggest the potential survival benefits of combined chemotherapy and radiotherapy. Further studies, preferably randomized clinical trials, are needed to confirm our results.

Abstract
Endometrial cancer (EC) is the most common gynecological cancer in developed countries. Most patients are diagnosed at an early stage with a low risk of relapse. However, there is a group of patients with a high risk of relapse and poor prognosis. Despite the recent publication of randomized trials, the adjuvant treatment of high-risk EC is still to be defined and there are many open questions about the best approach and the right timing. Unfortunately, the survival of metastatic or recurrent EC is short, due to the poor results of chemotherapy and the lack of a second line of treatment. Advances in the knowledge of the molecular abnormalities in EC have permitted the development of promising targeted therapies.

Abstract
The incidence of endometrial cancer is increasing, and the age of onset is younger than in prior years. Although endometrial cancer still occurs more commonly in older women, for whom the mortality rate is increasing, it also is being diagnosed in younger and younger women. The underlying cause of the increase in incidence is the epidemic of obesity and the resulting hyperinsulinemia. Conservative treatment may be indicated for younger women who wish to retain their fertility. Lifestyle modifications such as diet and exercise can modulate the risk of developing endometrial cancer as well as prevent recurrence and other comorbidities associated with obesity.

Abstract
PURPOSE To evaluate disease-specific survival (DSS) outcomes in Stage II endometrioid endometrial cancer (EC) patients based on pathology and treatment information including adjuvant radiotherapy and lymph node assessment. METHODS AND MATERIALS Using the Surveillance, Epidemiology, and End Results database, 2877 patients with Stage II EC diagnosed between 2004 and 2012 treated with radiation were identified. DSS was determined for different modalities of radiation. Kaplan-Meier estimates of survival and Cox regression modeling were used to explore the risk associated with various factors on DSS. RESULTS The 4-year DSS for the study population was 90%. Radiation was associated with improved 4-year DSS when compared to no radiotherapy (p = 0.03). Patients with Grade 2 and 3 tumors had improved 4-year DSS with radiation (94% vs. 90%, p = 0.02 and 81% vs. 73%, p = 0.15), respectively, but no differences in DSS when vaginal brachytherapy alone was compared with external beam alone or both. Patients with Grade 2 (p = 0.002) and Grade 3 (p < 0.001) tumors without a lymph node dissection (LND) had worse DSS compared to patients with any LND. Patients with Grade 3 tumors without an LND who received radiation showed improved DSS (p = 0.008). Multivariable analysis revealed that age >60 years (p < 0.001), Grade 3 (p < 0.001), no radiotherapy (p = 0.05), and no LNDs (p < 0.001) were significant prognostic factors for worse DSS. CONCLUSIONS Adjuvant radiation, whether delivered by brachytherapy or external beam radiation, is associated with improved DSS in Stage II EC patients with high-grade tumors, therefore brachytherapy may be sufficient.

Abstract
PURPOSE Previous studies of stage II endometrial cancer have included cancers with cervical glandular involvement, a factor no longer associated with risk of recurrence. In order to better assess relapse patterns and the impact of adjuvant therapy, a retrospective analysis was conducted for patients with modern stage II endometrial cancer, defined as cervical stromal invasion. MATERIALS AND METHODS Patients diagnosed with surgically staged FIGO stage II endometrial cancer at the UPMC Hillman Cancer Center from 1990-2013 were reviewed. Factors associated with rates of locoregional control (LRC), distant metastasis (DM), disease-free survival (DFS), and overall survival (OS) were analyzed using the log rank test. RESULTS 110 patients with FIGO stage II disease were identified. Most (84.5%) received EBRT±BT, with 13.6% receiving BT alone. With a median follow-up of 64.6months, the 5-year actuarial rates of LRC, DM, DFS, and OS were 94.9%, 85.1%, 67.9%, and 75.0%, respectively. With 5 locoregional failures, the only factor predictive of LRC was pelvic lymph node dissection. Characteristics associated with DM included age, LVSI, depth of myometrial invasion, and receipt of chemotherapy. Factors predictive of both DFS and OS were age, grade, adverse histology, LVSI, depth of myometrial invasion, and receipt of chemotherapy. CONCLUSIONS This represents the largest single-institution study for modern stage II endometrial cancer, confirming high rates of pelvic disease control after surgery and adjuvant therapy. With most patients receiving adjuvant radiotherapy, the predominant mode of failure, albeit low in absolute number, remains distant metastases.

External pelvic and vaginal irradiation vs. vaginal irradiation alone as postoperative therapy in women with early stage uterine serous carcinoma: Results of a National Cancer Database analysis.

Abstract
PURPOSE Adjuvant treatment in early stage uterine serous carcinoma (USC) usually consists of chemotherapy with vaginal brachytherapy (VB), pelvic external beam radiation therapy (EBRT), or combination. We compared survival outcomes across these various radiation treatment modalities using the National Cancer Database. METHODS AND MATERIALS The National Cancer Database was queried for adult females with histologically confirmed International Federation of Gynecology and Obstetrics 1988 Stage I-II USC diagnosed from 2003 to 2013 treated definitively with hysterectomy, adjuvant chemotherapy, and radiation therapy. χ2 tests were used to assess differences by radiation type (VB, pelvic EBRT, and EBRT + VB) and various clinical variables. Kaplan-Meier and log-rank test methods were used to evaluate survival outcomes. Risk factors related to overall survival were identified by univariate and multivariate analysis. RESULTS We identified 1336 patients with USC who met our inclusion criteria. Most patients were treated with VB (66%) compared with EBRT (21%) or combination EBRT + VB (13%). The proportion of patients who received EBRT (including EBRT + VB) was higher for those who did not have a lymph node dissection or with fewer dissected lymph nodes. Patients treated with VB alone had longer 5-year survival rates (84% [95% confidence interval: 80, 90]) than those treated with EBRT (75% [95% confidence interval: 69, 80]) (p < 0.001). On multivariate analysis, the presence of lymphovascular space invasion (hazard ratio, 2.48; p < 0.001) and the absence of a lymph node dissection (hazard ratio, 2.24; p = 0.047) were independent predictors of overall survival. CONCLUSIONS This large hospital-based study suggests that VB alone may be sufficient for adjuvant radiation treatment in women with USC treated with adjuvant chemotherapy and who underwent an adequate surgical staging.

Abstract
OBJECTIVES There is uncertainty surrounding the prognostic value and clinical utility of peritoneal cytology in endometrial cancer. Our primary objective was to determine if positive cytology is associated with disease-free and overall survival in women treated surgically for endometrial cancer, specifically those with low or intermediate risk disease. METHODS This was a retrospective population-based cohort study of British Columbia Cancer Registry patients who underwent surgery with peritoneal washings for endometrioid-type endometrial cancer from 2003 to 2009. Low risk was defined as Stage IA grade 1 or 2, and intermediate risk defined as Stage IA grade 3, or Stage IB grade 1 or 2 tumours. Five-year overall and disease free-survival were assessed using Kaplan-Meier estimation. Potential covariates including peritoneal cytology, grade, depth of myometrial invasion, LVSI, age, and adjuvant therapy were evaluated in a multivariable Cox proportional hazards model. RESULTS There were 849 patients, of whom 370 (43.6%) and 298 (35.1%) had low- and intermediate-risk disease, respectively. Overall, forty-nine (5.8%) patients had positive cytology, including 6 and 9 with low- and intermediate-risk respectively (2.2% within low and intermediate risk combined). Positive peritoneal cytology was not significantly associated with disease-free (HR 3.17, 95% CI 0.91-11.03) or overall survival (HR 1.33, 95% CI 0.47-3.76) in low and intermediate risk patients. Only age and extensive LVSI were associated with lower overall survival (HR 1.10, 95% CI 1.08-1.13, and HR 2.39, 95% CI 1.02-5.61, respectively). CONCLUSIONS Positive peritoneal cytology was not associated with disease-free and overall survival in women with low and intermediate risk endometrial cancer.

Abstract
This article aims to review the risk stratification of endometrial cancer, treatment rationale, outcomes, treatment planning, and treatment recommendations of vaginal brachytherapy (VBT) in the postoperative management of endometrial cancer patients. The authors performed a thorough review of the literature and reference pertinent articles pertaining to the aims of this review. Adjuvant VBT for early-stage endometrial cancer patients results in very low rates of vaginal recurrence (0-3.1%) with low rates of late toxicity which are primarily vaginal in nature. Post-Operative Radiation Therapy in Endometrial Cancer 2 (PORTEC-2) supports that VBT results in noninferior rates of vaginal recurrence compared to external beam radiotherapy for the treatment of high-intermediate risk patients. VBT as a boost after external beam radiotherapy, in combination with chemotherapy, and for high-risk histologies have shown excellent results as well though randomized data do not exist supporting VBT boost. There are many different applicators, dose-fractionation schedules, and treatment planning techniques which all result in favorable clinical outcomes and low rates of toxicity. Recommendations have been published by the American Brachytherapy Society and the American Society of Radiation Oncology to help guide practitioners in the use of VBT. Data support that patients and physicians prefer joint decision making regarding the use of VBT, and patients often desire additional treatment for a marginal benefit in risk of recurrence. Discussions regarding adjuvant therapy for endometrial cancer are best performed in a multidisciplinary setting, and patients should be counseled properly regarding the risks and benefits of adjuvant therapy.

Abstract
OBJECTIVES Our aim was to assess current surgical practices and use of adjuvant therapy in the treatment of FIGO (International Federation of Gynecology and Obstetrics) stage I endometrioid endometrial cancer. METHODS A 19-question survey was developed and sent to all Society of Gynecologic Oncologist members by e-mail. Data were collected anonymously using Internet-based survey software. Respondents were asked questions regarding preoperative evaluation, surgical approach, lymph node dissection (LND), and adjuvant therapy. RESULTS A total of 1399 surveys were distributed, 320 (23%) members completed the survey. Ninety-seven percent of respondents were gynecologic oncologists or fellows, and 87% treat 30 or more endometrial cancer patients yearly. Respondents were more likely to order preoperative tests such as computed tomography abdomen/pelvis and CA-125 for biopsy-proven grade 3 disease versus grade 1 (82% vs 29%). Robot-assisted laparoscopy was the preferred surgical approach (66%), followed by conventional laparoscopy (21%). Twenty-six percent of respondents perform LND in all cases. Forty-eight percent describe their LND as complete, to the level of the inferior mesenteric artery. Adjuvant therapy was recommended more often with increasing myometrial invasion, tumor grade, and lymphovascular space invasion. Vaginal brachytherapy was the most commonly recommended adjuvant therapy for stage IA. For stage IB, grade 3, positive lymphovascular space invasion disease, respondents were more likely to combine vaginal brachytherapy with external beam radiotherapy and/or chemotherapy. Older patients were more likely to have adjuvant therapy in earlier stages of disease than younger patients. CONCLUSIONS Our findings demonstrate that respondents are individualizing care based on preoperative, intraoperative, and pathologic findings. As expected, adjuvant treatment is recommended for patients with higher stage and grade disease. Robot-assisted hysterectomy and chemotherapy are now commonly used in the management of this disease. We anticipate that new trends will continue to emerge as results from additional studies become available.

Abstract
: Level I evidence exists for use of adjuvant chemotherapy in stage IIIC endometrial cancer (positive lymph nodes), although results of randomized trials have varied. Chemotherapy is also often recommended for high-risk subsets of stage I disease, such as serous carcinomas, although prospective trial data to validate this practice are lacking. Carboplatin plus paclitaxel is the current standard regimen, based on extrapolation of data from the metastatic setting. Several clinical trials have compared adjuvant pelvic radiotherapy alone to a combination of radiotherapy and chemotherapy with mixed results. One of the largest of these trials, Postoperative Radiation Therapy in Endometrial Carcinoma 3 (PORTEC-3), has completed accrual and is awaiting data maturation. Metastatic disease is not curable. For tumors of low-grade endometrioid histology with a prolonged time to recurrence, endocrine therapy with a progestin-based regimen is appropriate. Chemotherapy will be used in most other cases, and the standard first-line regimen is carboplatin and paclitaxel. Few chemotherapy agents have been shown to produce meaningful response rates in the second-line setting. Molecularly targeted therapies such as mTOR inhibitors and antiangiogenic agents including bevacizumab have been studied but their role in the armamentarium remains uncertain. IMPLICATIONS FOR PRACTICE Following surgical resection and staging for endometrial cancer, adjuvant chemotherapy with carboplatin and paclitaxel can be administered to patients with a high risk for recurrence. This includes patients with stage IIIC disease with positive lymph nodes, and high-risk subsets of stage I disease such as serous carcinomas. In the metastatic setting, endocrine therapy can be considered, particularly for patients with lower-grade disease and a prolonged time to recurrence. Combined therapy with carboplatin and paclitaxel is the standard of care used for front-line chemotherapy. Antiangiogenic agents are clearly active, but how they should be integrated into treatment is not yet determined. Immunotherapy is a promising direction for patients with mismatch repair-deficient or polymerase ε-mutated tumors.

Abstract
BACKGROUND About 15% of patients with endometrial cancer have high-risk features and are at increased risk of distant metastases and endometrial cancer-related death. We designed the PORTEC-3 trial to investigate the benefit of adjuvant chemoradiotherapy compared with radiotherapy alone for women with high-risk endometrial cancer. METHODS PORTEC-3 was a multicentre, open-label, randomised, international trial. Women with high-risk endometrial cancer were randomly allocated (1:1) to radiotherapy alone (48·6 Gy) in 1·8 Gy fractions five times a week or chemoradiotherapy (two cycles concurrent cisplatin 50 mg/m(2) and four adjuvant cycles of carboplatin area under the curve [AUC] 5 and paclitaxel 175 mg/m(2)) using a biased coin minimisation procedure with stratification for participating centre, lymphadenectomy, stage of cancer, and histological type. The primary endpoints of the PORTEC-3 trial were overall survival and failure-free survival analysed in the intention-to-treat population. This analysis focuses on 2-year toxicity and health-related quality of life as secondary endpoints; analysis was done according to treatment received. Health-related quality of life was assessed with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) the cervix cancer module and chemotherapy and neuropathy subscales of the ovarian cancer module at baseline, after radiotherapy and at 6, 12, 24, 36, and 60 months after randomisation. Adverse events were graded with Common Terminology Criteria for Adverse Events version 3.0. The study was closed on Dec 20, 2013, after achieving complete accrual, and follow-up remains ongoing for the primary outcomes analysis. This trial is registered with ISRCTN.com, number ISRCTN14387080, and with ClinicalTrials.gov, number NCT00411138. FINDINGS Between Sept 15, 2006, and Dec 20, 2013, 686 women were randomly allocated in the PORTEC-3 trial. Of these, 660 met eligibility criteria, and 570 (86%) were evaluable for health-related quality of life. Median follow-up was 42·3 months (IQR 25·8-55·1). At completion of radiotherapy and at 6 months, EORTC QLQ-C30 functioning scales were significantly lower (worse functioning) and health-related quality of life symptom scores higher (worse symptoms) for the chemoradiotherapy group compared with radiotherapy alone, improving with time. At 12 and 24 months, global health or quality of life was similar between groups, whereas physical functioning scores remained slightly lower in patients who received chemoradiotherapy compared with patients who received radiotherapy alone. At 24 months, 48 (25%) of 194 patients in the chemoradiotherapy group reported severe tingling or numbness compared with 11 (6%) of 170 patients in the radiotherapy alone group (p<0·0001). Grade 2 or worse adverse events were found during treatment in 309 (94%) of 327 patients in the chemoradiotherapy group versus 145 (44%) of 326 patients in the radiotherapy alone group, and grade 3 or worse events were found in 198 (61%) of 327 patients in the chemoradiotherapy group versus 42 (13%) of 326 patients in the radiotherapy alone group (p<0·0001), with most of the grade 3 adverse events being haematological (45%). At 12 and 24 months, no significant differences in grade 3 or worse adverse events were found between groups; only grade 2 or higher sensory neuropathy adverse events persisted at 24 months (25 [10%] of 240 patients in the chemoradiotherapy group vs one [<1%] of 247 patients in the radiotherapy alone group; p<0·0001). INTERPRETATION Despite the increased physician and patient-reported toxicities, this schedule of adjuvant chemotherapy given during and after radiotherapy in patients with high-risk endometrial cancer is feasible, with rapid recovery after treatment, but with persistence of patient-reported sensory neurological symptoms in 25% of patients. We await the analysis of primary endpoints before final conclusions are made.

Abstract
To improve survival in women with endometrial cancer, we need to look at the "big picture" beyond initial treatment. Although the majority of women will be diagnosed with early stage disease and are cured with surgery alone, there is a subgroup of women with advanced and high-risk early stage disease whose life expectancy may be prolonged with the addition of chemotherapy. Immunohistochemistry will help to identify those women with Lynch syndrome who will benefit from more frequent colorectal cancer surveillance and genetic counseling. If they happen to be diagnosed with colorectal cancer, this information has an important therapeutic implication. And finally, because the majority of women will survive their diagnosis of endometrial cancer, they remain at risk for breast and colorectal cancer, so these women should be counselled about screening for these cancers. These three interventions will contribute to improving the overall survival of women with endometrial cancer.

Abstract
In 2014, 9 topics were selected as major advances in clinical research for gynecologic oncology: 2 each in cervical and corpus cancer, 4 in ovarian cancer, and 1 in breast cancer. For cervical cancer, several therapeutic agents showed viable antitumor clinical response in recurrent and metastatic disease: bevacizumab, cediranib, and immunotherapies including human papillomavirus (HPV)-tumor infiltrating lymphocytes and Z-100. The HPV test received FDA approval as the primary screening tool of cervical cancer in women aged 25 and older, based on the results of the ATHENA trial, which suggested that the HPV test was a more sensitive and efficient strategy for cervical cancer screening than methods based solely on cytology. For corpus cancers, results of a phase III Gynecologic Oncology Group (GOG) 249 study of early-stage endometrial cancer with high-intermediate risk factors are followed by the controversial topic of uterine power morcellation in minimally invasive gynecologic surgery. Promising results of phase II studies regarding the effectiveness of olaparib in various ovarian cancer settings are summarized. After a brief review of results from a phase III study on pazopanib maintenance therapy in advanced ovarian cancer, 2 outstanding 2014 ASCO presentations cover the topic of using molecular subtypes in predicting response to bevacizumab. A review of the use of opportunistic bilateral salpingectomy as an ovarian cancer preventive strategy in the general population is presented. Two remarkable studies that discussed the effectiveness of adjuvant ovarian suppression in premenopausal early breast cancer have been selected as the last topics covered in this review.

Abstract
Endometrial cancer is the most common gynaecological tumour in developed countries, and its incidence is increasing. The most frequently occurring histological subtype is endometrioid adenocarcinoma. Patients are often diagnosed when the disease is still confined to the uterus. Standard treatment consists of primary hysterectomy and bilateral salpingo-oophorectomy, often using minimally invasive approaches (laparoscopic or robotic). Lymph node surgical strategy is contingent on histological factors (subtype, tumour grade, involvement of lymphovascular space), disease stage (including myometrial invasion), patients' characteristics (age and comorbidities), and national and international guidelines. Adjuvant treatment is tailored according to histology and stage. Various classifications are used to assess the risks of recurrence and to determine optimum postoperative management. 5 year overall survival ranges from 74% to 91% in patients without metastatic disease. Trials are ongoing in patients at high risk of recurrence (including chemotherapy, chemoradiation therapy, and molecular targeted therapies) to assess the modalities that best balance optimisation of survival with the lowest adverse effects on quality of life.

Recurrences and toxicity after adjuvant vaginal brachytherapy in Stage I-II endometrial cancer: A monoinstitutional experience. Brachytherapy 2015; 15:177-84. [PMID: 26727332 DOI: 10.1016/j.brachy.2015.10.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2015] [Revised: 10/08/2015] [Accepted: 10/28/2015] [Indexed: 01/20/2023]
Abstract
PURPOSE To evaluate the incidences of vaginal recurrence and toxicity after vaginal brachytherapy in Stage I-II endometrial cancer. METHODS AND MATERIALS Between 2003 and 2012, 150 high-intermediate-risk Stage I and 7 Stage II patients, median age 64 years, underwent surgery, with or without lymphadenectomy, and 3D brachytherapy: 7 Gy, at 5 mm depth from applicator surface, for 3-week fractions. The effects of age, grading, number of excised lymph nodes and pathologic stage on loco-regional relapse (LRR), metastases, and tumor-related death were investigated. Vaginal toxicity was evaluated during followup visits. RESULTS At 83 months of median followup, 144 patients were disease free, 2 in relapse, 7 deceased from disease, and 4 from other causes. One vaginal (0.6%), five nodal (3.2%), three pelvic over the vaginal cuff (1.9%), and one distant recurrences were seen (0.6%). The 5-year probability of LRR-free, distant metastasis-free and cause-specific survivals for all patients were 93.6% (95% confidence interval [CI]: 88.1-96.7), 97.8% (95% CI: 93.2-99.3), and 96.5% (95% CI: 93.5-99.5) and for Stage I 95.7% (95% CI: 92.2-9.1), 99.3% (95% CI: 98.0-100), and 97.7% (95% CI: 95.2-100), respectively. At multivariate analysis, Stage II disease and more than 12 lymph nodes sampled were associated with LRR (hazard ratio [HR]: 3.88; 95% CI: 1.390-10.878; p = 0.010 and HR: 6.952; 95% CI: 1.591-30.385; p = 0.010) and Stage II with metastasis and tumor-related death (HR: 23.057; 95% CI: 2.296-231.485; p = 0.008 and HR: 4.324; 95% CI: 1.223-15.290; p = 0.023). Vaginal acute and chronic toxicity was 16% and 55.4%, respectively, all only Grades 1-2. CONCLUSIONS For high-to-intermediate-risk Stage I endometrial cancer, 3D vaginal brachytherapy achieved good local control and low toxicity. In Stage II, patients brachytherapy could be administered after complete surgical staging.

Abstract
The first joint European Society for Medical Oncology (ESMO), European SocieTy for Radiotherapy & Oncology (ESTRO) and European Society of Gynaecological Oncology (ESGO) consensus conference on endometrial cancer was held on 11-13 December 2014 in Milan, Italy, and comprised a multidisciplinary panel of 40 leading experts in the management of endometrial cancer. Before the conference, the expert panel prepared three clinically relevant questions about endometrial cancer relating to the following four areas: prevention and screening, surgery, adjuvant treatment and advanced and recurrent disease. All relevant scientific literature, as identified by the experts, was reviewed in advance. During the consensus conference, the panel developed recommendations for each specific question and a consensus was reached. Results of this consensus conference, together with a summary of evidence supporting each recommendation, are detailed in this article. All participants have approved this final article.

Abstract
PURPOSE Uterine clear-cell carcinoma (UCCC) is a rare subset of type II endometrial carcinoma with a poor prognosis relative to the most common type of endometrioid carcinoma. Due to its rarity, there has been limited direct evidence of the efficacy of specific adjuvant therapy posthysterectomy in women with UCCC. We present a review of current literature regarding adjuvant therapy of uterine clear cell carcinoma. METHODS We searched for English-language publications through Pubmed using a combination of the following key words: endometrial carcinoma, clear cell carcinoma, recurrence, prognosis, adjuvant therapy, radiation treatment and chemotherapy. Due to the rarity of UCCC, studies were not limited by design or number of patients. RESULTS There is a paucity of randomized prospective controlled studies focusing on UCCC adjuvant therapy. Findings have largely been derived from retrospective studies of type II endometrial carcinomas or all endometrial cancers as a group. Very few retrospective studies were found to focus on UCCC adjuvant therapy, although certain larger studies did have subset analyses of UCCC patients. CONCLUSIONS For early stage disease, locoregional radiotherapy, especially vaginal brachytherapy, has evidence of efficacy. The therapeutic gain of radiotherapy may be further improved with the addition of systemic chemotherapy. Evidence for combined radiation therapy with systemic chemotherapy in women with advanced stage UCCC has remained debatable. UCCC-specific studies are needed to determine the best adjuvant therapy for UCCC without the confounding effects of USC and other endometrial cancers.

Abstract
PURPOSE Report current practice patterns for postoperative endometrial cancer emphasizing vaginal brachytherapy (VBT). METHODS AND MATERIALS A 38-item survey was e-mailed to 1,598 American Brachytherapy Society (ABS) members and 4,329 US radiation oncologists in 2014 totaling 5,710 recipients. Responses of practitioners who had delivered VBT in the previous 12 months were included in the analysis. Responses were tabulated to determine relative frequency distributions. χ(2) analysis was used to compare current results with those from the 2003 ABS survey. RESULTS A total of 331 respondents initiated the VBT survey, of whom 289 (87.3%) administered VBT in the prior 12 months. Lymph node dissection and number of nodes removed influenced treatment decisions for 90.5% and 69.8%, respectively. High-dose-rate was used by 96.2%. The most common vaginal length treated was 4 cm (31.0%). Three-dimensional planning was used by 83.2% with 73.4% of those for the first fraction only. Doses to normal tissues were reported by 79.8%. About half optimized to the location of dose specification and/or normal tissues. As monotherapy, the most common prescriptions were 7 Gy for three fractions to 0.5-cm depth and 6 Gy for five fractions to the surface. As a boost, the most common prescriptions were 5 Gy for three fractions to 0.5-cm depth and 6 Gy for three fractions to the vaginal surface. Optimization points were placed at the apex and lateral vagina by 73.1%. Secondary quality assurance checks were performed by 98.9%. CONCLUSIONS VBT is a common adjuvant therapy for endometrial cancer patients, most commonly with HDR. Fractionation and planning processes are variable but generally align with ABS recommendations.
