Racial-Ethnic and Socioeconomic Disparities in Guideline-Adherent Treatment for Endometrial Cancer. Obstet Gynecol 2021; 138:21-31. [PMID: 34259460 PMCID: PMC10403994 DOI: 10.1097/aog.0000000000004424] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Accepted: 03/04/2021] [Indexed: 01/22/2023]
Abstract
OBJECTIVE To evaluate the association of race-ethnicity and neighborhood socioeconomic status with adherence to National Comprehensive Cancer Network guidelines for endometrial carcinoma. METHODS Data are from the SEER (Surveillance, Epidemiology, and End Results) cancer registry of women diagnosed with endometrial carcinoma for the years 2006-2015. The sample included 83,883 women after inclusion and exclusion criteria were applied. Descriptive statistics, bivariate analyses, univariate, and multivariate logistic regression models were performed to evaluate the association between race-ethnicity and neighborhood socioeconomic status with adherence to treatment guidelines. RESULTS After controlling for demographic and clinical covariates, Black (odds ratio [OR] 0.89, P<.001), Latina (OR .92, P<.001), and American Indian or Alaska Native (OR 0.82, P=.034) women had lower odds of receiving adherent treatment and Asian (OR 1.14, P<.001) and Native Hawaiian or Pacific Islander (OR 1.19 P=.012) women had higher odds of receiving adherent treatment compared with White women. After controlling for covariates, there was a gradient by neighborhood socioeconomic status: women in the high-middle (OR 0.89, P<.001), middle (OR 0.84, P<.001), low-middle (OR 0.80, P<.001), and lowest (OR 0.73, P<.001) neighborhood socioeconomic status categories had lower odds of receiving adherent treatment than the those in the highest neighborhood socioeconomic status group. CONCLUSIONS Findings from this study suggest there are racial-ethnic and neighborhood socioeconomic disparities in National Comprehensive Cancer Network treatment adherence for endometrial cancer. Standard treatment therapies should not differ based on sociodemographics. Interventions are needed to ensure that equitable cancer treatment practices are available for all individuals, regardless of racial-ethnic or socioeconomic background.

Abstract
BACKGROUND Adherence to National Comprehensive Cancer Network guidelines have been adopted as the standard of care for various cancers and have been cited to have survival benefits. Few studies have examined the association of adherent treatment and endometrial cancer survival among various racial/ethnic groups and socioeconomic statuses. METHODS Between January 1, 2006 and December 31, 2015, 83,673 women diagnosed with endometrial carcinomas were identified from the Surveillance, Epidemiology, and End Results database. Descriptive statistics of demographic and clinical characteristics were performed. Cox-proportional hazards models were used to examine the effect on cause-specific survival for adherence to guidelines across racial/ethnic and socioeconomic groups. RESULTS Within our sample, 59.5% were treated according to guidelines. Nonadherence to treatment guidelines was significantly associated with decreased survival compared with adherent care (adjusted hazard ratio [HR], 1.59; 95% CI, 1.52-1.67). Being of Black (adjusted HR, 1.41; 95% CI, 1.32-1.51) or Native Hawaiian/Pacific Islander (adjusted HR, 1.44; 95% CI, 1.19-1.73) race/ethnicity compared with White women was significantly associated with worse survival. Being of Asian race/ethnicity (adjusted HR, 0.86, 95% CI, 0.78-0.94) was significantly associated with improved survival compared with White women. Lower neighborhood socioeconomic status was associated with a negative effect on survival relative to women in the highest socioeconomic status category. CONCLUSIONS Findings from this study suggest treatment adherence is an independent predictor of improved survival; however, improved survival was not observed equally among all racial/ethnic and socioeconomic status groups. LAY SUMMARY The National Comprehensive Cancer Network (NCCN) has developed guidelines for physicians to follow in treating various cancers. Within this study of 83,673 women with endometrial cancer, 59.5% of women were treated according to the NCCN guidelines. The findings suggest following NCCN guidelines for treatment of endometrial cancer improves survival. Black or Native Hawaiian/Pacific Islander race and lower neighborhood socioeconomic status has worse survival rates compared with other groups, indicating the importance of exploring other factors that may shape treatment across racial/ethnic and socioeconomic status groups.

Abstract
BACKGROUND Endometrial cancer is the fourth most prevalent cancer in Canadian women. Radiotherapy (RT) is frequently recommended as an adjuvant treatment. There is a high prevalence (>80%) of urinary incontinence (UI) after RT. It is plausible that UI is associated, at least in part, with alterations of the pelvic-floor muscles (PFM). OBJECTIVE The aim of this exploratory study was to compare the PFM functional properties of women reporting UI after hysterectomy and RT for endometrial cancer with those of women with a history of hysterectomy but without UI. DESIGN A descriptive cross-sectional study was conducted. Eleven women were recruited for the affected group, and 18 were recruited for the comparison group. METHODS Urogenital and bowel functions were assessed using International Consultation on Incontinence Questionnaires, and PFM properties were evaluated using a Montreal dynamometer. Nonparametric tests were used for comparison of personal characteristics, functional status, and muscle properties. A correspondence analysis detailed the association between UI severity and PFM properties. RESULTS Maximal opening of dynamometer branches, maximal vaginal length, PFM maximum force and rate of force development in a strength test, and number of rapid contractions during a speed test were reduced in the affected group. No significant difference was found for the endurance test. The severity of UI was found to correspond to the rate of force development and the number of rapid contractions in a speed test, endurance, age, and vaginal length. LIMITATIONS The results are limited to the population studied. The small sample size limited the strength of the conclusions. CONCLUSIONS Some evidence of alterations in PFM properties were found in women with UI after hysterectomy and RT for endometrial cancer. These alterations appeared to be associated with UI, suggesting a possible role for rehabilitation.

Therapeutic role of systematic lymphadenectomy in early-stage endometrial cancer: A systematic review. Oncol Lett 2016; 11:3849-3857. [PMID: 27313706 DOI: 10.3892/ol.2016.4467] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2014] [Accepted: 01/18/2016] [Indexed: 12/29/2022] Open
Abstract
The purpose of the current review was to examine whether systematic lymphadenectomy is safe and effective for treating early-stage endometrial cancer. PubMed, Embase, the Cochrane Library and the China National Knowledge Infrastructure databases were systematically searched during April 2014 to identify studies comparing the use of systematic lymphadenectomy and no systematic lymphadenectomy in parallel for the treatment of early-stage endometrial cancer. A total of 13 eligible studies involving 51,155 patients were included in this review. The median overall survival (OS) rate at 5 years following lymphadenectomy was 90% (range, 73.1-98.3%) for patients undergoing the systematic procedure and 88.2% (range, 68-98.4%) for patients not undergoing the systematic procedure. For the two types of lymphadenectomy, OS has tended to improve over the last 20 years. The combined rate of disease-free and progression-free survival was higher in patients who underwent systematic lymphadenectomy, and the recurrence rate was lower. In particular, systematic lymphadenectomy was associated with markedly higher OS than the non-systematic procedure for patients with intermediate- and high-risk endometrial cancer when ≥11 lymph nodes were removed. Systematic lymphadenectomy demonstrates clinical benefit in patients with early-stage endometrial cancer and should thus be a standard treatment option. In conclusion, systematic lymphadenectomy leads to higher OS than no systematic lymphadenectomy in intermediate- and high-risk patients with early-stage endometrial cancer, particularly when the procedure removes ≥11 lymph nodes.

Abstract
Uterine sarcomas are an uncommon and heterogeneous group of tumors that account for 3-7% of the malignant neoplasms of the uterus and approximately 1% of all malignant tumors of the female genital system. The main clinical manifestations are abnormal uterine bleeding in pre- or postmenopausal women. Pelvic pain, abdominal distension, urinary urgency, and profuse and fetid leukorrhea are other frequent complaints. The authors present a case of a 48-year-old patient that was in amenorrhea for 2 years, who sought treatment for vaginal bleeding. On physical examination, the abdomen was distended, painful in the hypogastrium and upon examination of the external genitalia, it was observed the exteriorization of an amorphous "mass". The patient was submitted to uterine curettage. The results of the histological examination revealed leiomyosarcoma. Staging workup showed an enlarged uterus with endometrial lesion, and non-calcified pulmonary nodules. The patient underwent a pan-hysterectomy and chemotherapy, and is under oncologic treatment. The authors call attention for the unusual form of presentation of this entity.

Abstract
OBJECTIVE The purpose of this study was to evaluate the therapeutic role of systematic retroperitoneal lymphadenectomy in patients with endometrial cancer. METHODS From December 2003 to December 2008, 349 eligible patients who underwent surgical staging procedures at primary treatment were retrospectively analyzed: systematic lymphadenectomy group (n = 246) and no-lymphadenectomy group (n = 103). Survival was analyzed using Kaplan-Meier method and Cox proportional hazards model. RESULTS Overall, patients who underwent lymphadenectomy improved 5-year disease-free survival (89.0% versus 80.7%, P = 0.019) and overall survival (92.8% versus 81.5%, P = 0.001) compared to those who did not undergo lymphadenectomy. Overall survival was not related to lymphadenectomy in 212 low-risk patients (93.1% versus 84.6%, P = 0.176). However, this association was found in 137 patients with intermediate and high-risk (86.2% versus 73.3%, P = 0.021). Multivariate Cox regression analysis showed that FIGO stage (P = 0.037) and lymphadenectomy (P = 0.023) were independent prognostic factors for overall survival. CONCLUSIONS Systematic retroperitoneal lymphadenectomy has a potentially therapeutic role on survival in surgically staged patients with endometrial cancer.

Abstract
PURPOSE To describe radiotherapeutic practice of the treatment of endometrial cancer in members of the Gynecologic Cancer Intergroup (GCIG). METHODS A survey was developed and distributed to the members of the GCIG. The GCIG is a global association of cooperative groups involved in the research and treatment of gynecologic neoplasms. RESULTS Thirty-four surveys were returned from 13 different cooperative groups. For the treatment of endometrial cancer after hysterectomy, mean (SD) pelvic dose was 47.37 (2.32) Gy. The upper border of the pelvic field was L4/5 in 14 respondents, L5/S1 in 13 respondents, and not specified in 6 surveys. When vaginal brachytherapy (VBT) was used in conjunction with external beam radiotherapy, most groups used high dose rate versus low dose rate on 24 versus 5 respondents, respectively. Twenty-eight of the 34 respondents performed computed tomographic simulation. Intensity-modulated radiotherapy was used routinely in 3 of the 34 respondents. For a para-aortic field, the upper border was, most commonly, at the T12-L1 interspace (17 of the 28 respondents), and the mean (SD) dose was 46.15 (2.18) Gy. For VBT alone after hysterectomy, 23 groups performed high-dose-rate brachytherapy (27.57 [10.13] Gy in a mean of 4.3 insertions), and 5 groups used low-dose-rate brachytherapy (41.45 [17.5] Gy). Nineteen of the 28 respondents measured the doses to the bladder and the rectum when performing VBT. For brachytherapy, there was no uniformity in the fraction of the vagina treated or the doses and schedules used. CONCLUSIONS Radiotherapy practices among member groups of the GCIG are similar in doses and dose per fraction with external beam. There is a moderate discrepancy in the brachytherapy practice after hysterectomy. There are no serious impediments to intergroup participation in radiation oncology practices among GCIG members with the use of external beam.

Abstract
BACKGROUND The objectives of the current study were to determine the prognostic factors associated with disease-specific survival (DSS) and to analyze the role of lymphadenectomy (LND) and oophorectomy in the management of uterine leiomyosarcomas (LMS). METHODS Data were abstracted from the Surveillance, Epidemiology, and End Results database (1988-2003). Kaplan-Meier and Cox proportional hazards regression models were used for analyses. RESULTS The median age of the 1396 patients was 52 years. There were 951 patients (68.1%) with International Federation of Gynecology and Obstetrics (FIGO) stage I disease, 43 patients (3.1%) with stage II disease, 99 patients (7.1%) with stage III disease, and 303 patients (21.7%) with stage IV disease. Distribution by tumor grade included 87 patients with grade 1 tumors, 208 with grade 2, and 509 patients with grade 3 tumors. The 5-year DSS rates for patients with stage I, II, III, and IV disease were 75.8%, 60.1%, 44.9%, and 28.7%, respectively. Lymph node metastases were identified in 23 of 348 patients (6.6%) who underwent LND. The 5-year DSS rate was 26% in patients who had positive lymph nodes compared with 64.2% in patients who had negative lymph nodes (P < .001). Of 341 patients aged <50 years with stage I or II disease, 240 (70.4%) underwent oophorectomy. There was no difference in 5-year DSS based on oophorectomy. On multivariate analysis, older age at diagnosis, more recent year of diagnosis, African-American race, higher tumor grade, higher stage of disease, and lack of primary surgical treatment all were associated significantly with worse survival. CONCLUSIONS Independent predictors of DSS in patients with uterine LMS included age, race, stage, grade, and primary surgery. Oophorectomy was not found to have an independent impact on survival.

Abstract
Although surgical pathological staging is the standard of care for uterine carcinoma, the benefits of a complete lymphadenectomy remain controversial. Evidence suggests that this procedure provides prognostic information and directs the use of appropriate adjuvant treatment in patients who are node-positive. Furthermore, it eliminates the need for adjuvant treatment in low-risk patients with negative nodes and no extrauterine spread of disease. Although the complications associated with this procedure raise the question as to whether all low-risk patients need a complete lymphadenectomy, the limitations of preoperative and intraoperative pathological analyses mean that lymphadenectomy in low-risk patients might still have merit. Future advances are warranted to enhance preoperative radiological and intraoperative pathological assessment to establish the risk of nodal disease. In this review, we assess the evidence on the prognostic and therapeutic benefits of a complete versus selective lymphadenectomy. Moreover, we discuss the complications associated with lymphadenectomy and identify subsets of low-risk patients who might not need to undergo this procedure.
