Weight Change Pattern and Survival Outcome of Women with Endometrial Cancer.

ABSTRACT: The aim of this study was to determine the association between weight change patterns and survival outcomes of women with endometrial cancer.This retrospective study examined surgically-staged endometrial cancer cases with available weight information between 1999 and 2013 (n = 665). Proportional body mass index (delta-BMI) change at 6 months, 1 and 2 years after hysterectomy was compared with baseline BMI and correlated to patient demographics, tumor characteristics, treatment type, and disease-free survival (DFS) and overall survival (OS).Mean BMI was 35.6, and 69 % of cases were obese. At 6 months, 1 and 2 years after surgery, 39.1, 51.6, and 57.0 % of the study population, respectively, gained weight compared with pre-treatment baseline. In univariate analysis, 6-month delta-BMI change was significantly associated with DFS and OS, demonstrating bidirectional effects (both p < 0.001): 5-year rates, ?15.0 % delta-BMI loss (33.5 and 59.1 %), 7.5-14.9 % loss (67.3 and 70.0 %), <7.5 % loss (87.8 and 95.7 %), <7.5 % gain (87.2 and 90.3 %), 7.5-14.9 % gain (64.6 and 67.6 %), and ?15.0 % gain (32.5 and 66.7 %). In multivariable analysis controlling for age, ethnicity, baseline BMI, histology, grade, stage, chemotherapy, and radiotherapy, 6-month delta-BMI change remained an independent prognostic factor for DFS and OS (all p < 0.05): adjusted hazard ratios, ?15 % delta-BMI loss (3.35 and 5.39), 7.5-14.9 % loss (2.35 and 4.19), 7.5-14.9 % gain (2.58 and 3.33), and ?15.0 % gain (2.50 and 3.45) compared with <7.5 % loss. Similar findings were observed at a 1-year time point (p < 0.05). Baseline BMI was not associated with survival outcome (p > 0.05).Our results demonstrated that endometrial cancer patients continued to gain weight after hysterectomy, and post-treatment weight change had bidirectional effects on survival outcome.

Project description:ObjectiveTo examine the survival outcomes in women with endometrial cancer who were taking low-dose aspirin (81-100 mg/d).MethodsA multicenter retrospective study was conducted examining patients with stage I-IV endometrial cancer who underwent hysterectomy-based surgical staging between January 2000 and December 2013 (N=1,687). Patient demographics, medical comorbidities, medication types, tumor characteristics, and treatment patterns were correlated to survival outcomes. A Cox proportional hazard regression model was used to estimate adjusted hazard ratio for disease-free and disease-specific overall survival.ResultsOne hundred fifty-eight patients (9.4%, 95% confidence interval [CI] 8.8-11.9) were taking low-dose aspirin. Median follow-up time for the study cohort was 31.5 months. One hundred twenty-seven patients (7.5%) died of endometrial cancer. Low-dose aspirin use was significantly correlated with concurrent obesity, hypertension, diabetes mellitus, and hypercholesterolemia (all P<.001). Low-dose aspirin users were more likely to take other antihypertensive, antiglycemic, and anticholesterol agents (all P<.05). Low-dose aspirin use was not associated with histologic subtype, tumor grade, nodal metastasis, or cancer stage (all P>.05). On multivariable analysis, low-dose aspirin use remained an independent prognostic factor associated with an improved 5-year disease-free survival rate (90.6% compared with 80.9%, adjusted hazard ratio 0.46, 95% CI 0.25-0.86, P=.014) and disease-specific overall survival rate (96.4% compared with 87.3%, adjusted hazard ratio 0.23, 95% CI 0.08-0.64, P=.005). The increased survival effect noted with low-dose aspirin use was greatest in patients whose age was younger than 60 years (5-year disease-free survival rates, 93.9% compared with 84.0%, P=.013), body mass index was 30 or greater (92.2% compared with 81.4%, P=.027), who had type I cancer (96.5% compared with 88.6%, P=.029), and who received postoperative whole pelvic radiotherapy (88.2% compared with 61.5%, P=.014). These four factors remained significant for disease-specific overall survival (all P<.05).ConclusionOur results suggest that low-dose aspirin use is associated with improved survival outcomes in women with endometrial cancer, especially in those who are young, obese, with low-grade disease, and who receive postoperative radiotherapy.

Project description:ImportanceAlthough primary debulking surgery (PDS) is often considered the criterion standard for treatment of stage IV endometrial cancer, PDS is associated with significant morbidity and poor survival. Neoadjuvant chemotherapy (NACT) has been proposed as an alternative treatment strategy.ObjectiveTo determine the use of and outcomes associated with NACT for women with stage IV endometrial cancer.Design, setting, and participantsThis cohort study used the National Cancer Database to identify women with stage IV endometrial cancer treated from January 1, 2010, to December 31, 2015. The cohort was limited to women aged 70 years or younger with minimal comorbidity (comorbidity score = 0). Women were stratified based on receipt of NACT or PDS. A propensity score analysis with inverse probability weighting was performed to balance the clinical characteristics of the groups. Survival was examined using flexible parametric Royston-Parmer models to account for time-varying hazards associated with use of NACT. An intention-to-treat (ITT) analysis was performed, as was a per-protocol (PP) analysis that included only women who received treatment with both chemotherapy and surgery (in either sequence). Data were analyzed from March 15, 2018, to July 20, 2018.Main outcomes and measuresUse of NACT and overall survival.ResultsOf a total of 4890 women (median age, 60 years [interquartile range, 54-65 years]) with stage IV endometrial cancer, NACT was used in 952 women (19.5%). Use of NACT increased from 106 of 661 women (16.0%; 95% CI, 13.2%-18.8%) in 2010 to 224 of 938 women (23.9%; 95% CI, 21.2%-26.6%) in 2015 (P < .001). In a multivariate model, more recent year of diagnosis (risk ratio [RR], 1.42; 95% CI, 1.21-1.79 for 2015 vs 2010), stage IVB disease (RR, 1.31; 95% CI, 1.03-1.67 for stage IVB vs IVA), and serous histology (RR, 1.38; 95% CI, 1.13-1.69 for serous vs endometrioid histology) were associated with use of NACT. In a propensity score-balanced cohort, use of NACT displayed a time-varying association with survival. In the ITT analysis, use of NACT was associated with decreased mortality for the first 3 months after diagnosis (hazard ratio [HR] at 2 months, 0.81; 95% CI, 0.66-0.99). After 4 months, the survival curves crossed, and receipt of NACT was associated with increased mortality (HR at 6 months, 1.23; 95% CI, 1.09-1.39). In the PP analysis, use of NACT was associated with decreased mortality for the first 8 months after diagnosis (HR at 6 months, 0.79; 95% CI, 0.63-0.98). After 9 months, the survival curves crossed, and receipt of NACT was associated with increased mortality (HR at 12 months, 1.22; 95% CI, 1.04-1.43).Conclusions and relevanceThe results of this cohort study suggest that women treated with PDS are at increased risk of early death but have a more favorable long-term prognosis. In contrast, results suggest that women treated with NACT, particularly if they ultimately undergo surgery, may have superior survival in the short term. Based on these findings, NACT may be appropriate for select patients with advanced uterine serous carcinoma.

Project description:BackgroundBody weight management was an important component in breast cancer survivorship care. The present study described the change patterns of body weight and waist-to-hip ratio (WHR) during the first 5 years of survival, and investigated potential factors associated with very substantial changes.Patients and methodsBased on a longitudinal cohort with 1462 Chinese women with breast cancer, anthropometric measurements including body weight, height, waist and hip circumferences were measured by trained interviewers following standard protocol at four time-points: baseline at study entry, 18-, 36- and 60-months follow up assessments (termed as T0, T1, T2 and T3, respectively). Body height was measured at baseline and body weight at cancer diagnosis were retrieved from medical record.ResultsCompared to weight at breast cancer diagnosis, the median weight change was - 0.5 kg, 0 kg, + 0.5 kg, and + 1 kg at T0, T1, T2 and T3, respectively. During the first 5 years of survival, the proportion of women who were obese have slightly increased. At 60-months after diagnosis, only 14.3% of women had weight gain by > 5 kg; and the percentage of women who had weight gain by > 10% was 10.7%. Nearly half of patients had abdominal obesity at study entry, and this proportion were gradually increased to nearly 70% at 60-months follow-up. Multivariate analysis indicated that older age, and frequent sports participation during the first 5 years of survival were related to lower risk of very substantial weight gain (> 10%) at 60-month follow-up; patients aged 40-49 years, having ≥2 comorbidities and ER negative were associated with less likelihood of very substantial WHR substantial increase (> 10%) at 60-month follow-up.ConclusionWeight gain was modest in Chinese breast cancer survivors during the first 5 years of survival, while central adiposity has become a contemporary public health issue. The incorporation of healthy weight and abdominal circumference patient education and management has a potential to improve cancer survivorship.
