Adjuvant sequential chemo and radiotherapy improves the oncological outcome in high risk endometrial cancer.

ABSTRACT: Evaluation of the impact of sequential chemoradiotherapy in high risk endometrial cancer (EC).Two hundred fifty-four women with stage IB grade 3, II and III EC (2009 FIGO staging), were included in this retrospective study.Stage I, II, and III was 24%, 28.7%, and 47.3%, respectively. Grade 3 tumor was 53.2% and 71.3% had deep myometrial invasion. One hundred sixty-five women (65%) underwent pelvic (+/- aortic) lymphadenectomy and 58 (22.8%) had nodal metastases. Ninety-eight women (38.6%) underwent radiotherapy, 59 (23.2%) chemotherapy, 42 (16.5%) sequential chemoradiotherapy, and 55 (21.7%) were only observed. After a median follow-up of 101 months, 78 women (30.7%) relapsed and 91 women (35.8%) died. Sequential chemoradiotherapy improved survival rates in women who did not undergo nodal evaluation (disease-free survival [DFS], p=0.040; overall survival [OS], p=0.024) or pelvic (+/- aortic) lymphadenectomy (DFS, p=0.008; OS, p=0.021). Sequential chemoradiotherapy improved both DFS (p=0.015) and OS (p=0.014) in stage III, while only a trend was found for DFS (p=0.210) and OS (p=0.102) in stage I-II EC. In the multivariate analysis, only age (? 65 years) and sequential chemoradiotherapy were statistically related to the prognosis.Sequential chemoradiotherapy improves survival rates in high risk EC compared with chemotherapy or radiotherapy alone, in particular in stage III.

Project description:This prospective randomized comparative trial study aimed to evaluate the therapeutic outcomes of radical nephroureterectomy and adjuvant chemotherapy (ACT) used in combination in high risk upper tract urothelial carcinoma (UTUC) patients with cardiovascular comorbidity. Based on the inclusion criteria of high-risk UTUC in EAU guidelines (updated in 2014), all eligible patients treated in our hospital from January 2014 to March 2018 were included, and cases with late disease, renal dysfunction, severe cardiopulmonary disease or other malignant tumors were excluded. The cases were randomized into two groups based on treatment regimen. Multivariate analyses were performed to analyze the influencing factors of survival outcome in the enrolled patients. The Cox proportional-hazards model and the Kaplan-Meier method were employed to assess progression free survival (PFS), overall survival (OS) and cancer specific survival (CSS). In addition, the potential adverse effects of chemotherapy were actively monitored. A total of 176 high-risk UTUC individuals with cardiovascular comorbidity were enrolled and evaluated in this study. Median follow-up durations were 30 months (range 6-54) in the RNU (n = 82) group and 36 months (range 6-54) in the RNU + ACT (n = 94) group. Multivariable analysis indicated that peri-operative cardiovascular events risk grade was independent prognostic factor for OS. Tumor size was independent prognostic factor for PFS and CSS. BMI and lymphovacular invasion were significant predictors of PFS. Clinical stage, lymph node involvement, and tumor grade were significant predictors of PFS, OS and CSS in these patients. Especially, chemotherapy was helpful in improving PFS [P < 0.001, HR = 6.327 (5.115-7.793)], OS [P = 0.013, HR = 2.336 (1.956-2.883)] and CSS [P = 0.008, HR = 3.073 (2.533-3.738)]. Kaplan-Meier analysis demonstrated that the oncologic outcomes of RNU treated high-risk UTUC patients were improved much significantly by ACT, including PFS [P = 0.0033, HR = 3.78 (3.13-4.55)], OS [P = 0.0397, HR = 1.39 (1.01-1.75)] and CSS [P = 0.0255, HR = 1.26 (1.07-1.45)]. Further analysis of the lymph node positive subgroup showed that the median time of oncologic events was enhanced in RNU + ACT treated individuals in comparison with the RNU group, including PFS (11.4 months vs. 31.9 months, P = 0.0018), OS (26.8 months vs. 36.3 months, P = 0.0255) and CSS (28.2 months vs. 39.3 months, P = 0.0197). In the T3/4 cohort, significantly increased median PFS (13.9 months vs. 36.3 months, P = 0.0217), OS (20.6 months vs. 32.2 months, P = 0.0183) and CSS (21.9 months vs. 38.4 months, P = 0.0226) were obtained in the combination group. Additionally, no severe adverse events (over grade 4) associated with chemotherapy were detected in the RNU + ACT group. In conclusion, ACT after radical surgery has statistically significant therapeutic effects on PFS, OS and CSS in high-risk UTUC patients with cardiovascular comorbidity.

Project description:BackgroundPelvic lymph node metastasis carries the highest impact on decreased survival among surgical-pathological risk factors for early-stage cervical cancer. Although concurrent administration of chemotherapy during postoperative radiotherapy is the current standard treatment for surgically treated high-risk early-stage cervical cancer, its effectiveness specific to node-positive disease has not been completely studied.ObjectiveTo examine the association between the use of concurrent chemotherapy and survival in women with early-stage cervical cancer and nodal metastasis receiving adjuvant radiotherapy.Materials and methodsThis is a population-based cohort study using the Surveillance, Epidemiology, and End Results Program from 1988 to 2016. Women with stage T1-2 cervical cancer with pelvic lymph node metastasis who underwent hysterectomy and received postoperative radiotherapy were examined. Trends, characteristics, and overall survival were compared between women who received postoperative radiotherapy alone (n = 729) or in combination with concurrent chemo-radiotherapy (n = 1809). Propensity score-based inverse probability of treatment weighting was used to account for the effect of measured covariates on treatment selection.ResultsAmong 2538 women, there was a marked increase in the use of concurrent chemotherapy from 1997 to 2000 (20.7% to 78.5%, P = .052), followed by a more gradual rise through 2016 (88.3%, P < .001). In a multivariable model, women with non-squamous cell carcinomas and those diagnosed more recently were more likely to receive concurrent chemo-radiotherapy, whereas older women were less likely to receive concurrent chemo-radiotherapy (all, P < .05). At the population level, the 5-year overall survival rates remained unchanged (annual percent change for 1997-2012: -0.1; 95% confidence interval, -1.2 to 1.0; P = .776). In a propensity score weighted cohort, women who received concurrent chemo-radiotherapy had a 5-year overall survival rate similar to women treated with radiotherapy alone (73.1% vs 73.6%; hazard ratio, 1.004; 95% confidence interval, 0.887-1.136; P = .955). Significant differences were also not seen in older women, nonsquamous types, stage T2 disease, and multiple node metastases (all, P > .05).ConclusionDespite the marked increase in the use of concurrent chemo-radiotherapy for women with early-stage cervical cancer and nodal metastases, there was no association between use of concurrent chemotherapy during postoperative radiotherapy and improved survival.
