Survival outcomes of adjuvant radiotherapy and chemotherapy in women with stage I serous papillary and clear cell carcinoma of the endometrium: a Korean multicenter study

An analysis of adjuvant chemoradiotherapy versus chemotherapy on the survival rates for patients with stage IB-III uterine serous carcinoma

The aim of the present study was to investigate whether a combination of chemotherapy plus radiotherapy was able to increase the overall survival rates compared with chemotherapy alone in stage IB-III uterine serous carcinoma. A total of 1096 patients (593 who had not received radiotherapy, and 503 who had) with primary stage IB-III uterine serous carcinoma who underwent surgery and received chemotherapy were included in the present study. The Kaplan-Meier method and Log-Rank tests showed that radiotherapy did not increase 5-year overall survival rates compared with the no-radiotherapy groups (52.3 cf. 50.8%, respectively; P = 0.641). Cox regression analysis subsequently corroborated that radiotherapy did not affect the 5-year overall survival rate (P = 0.635). Patients who were aged ≥ 60 years had a higher mortality rate [hazard ratio (HR), 1.712; 95% confidence interval (95% CI), 1.385-2.117; P < 0.05]. The 5-year overall survival rates were found to be lower in the groups where the regional lymph nodes had not been removed (HR 0.645; 95% CI 0.508-0.821; P < 0.05). Chemotherapy plus radiotherapy was found to not be associated with improved 5-year overall survival rates. However, chemotherapy may be a better treatment option for patients with primary stage IB-III uterine serous carcinoma who have undergone surgery.

Anesthesia management and outcomes of gynecologic oncology surgery

OBJECTIVES

This study assessed postoperative mortality, morbidity, and complications associated with anesthesia administration for gynecologic oncology abdominal surgery and investigated the risk factors for the development of these complications.

METHODS

We conducted a retrospective cohort study analyzing the data of patients who underwent elective gynecologic oncology surgery between 2010 and 2017. The demographic data; comorbidities; preoperative anemia; Charlson Comorbidity Index; anesthesia management; complications; preoperative, intraoperative, and postoperative periods; mortality; and morbidity were investigated. The patients were classified as surviving or deceased. Subgroup analyses of patients with endometrial, ovarian, cervical, and other cancers were performed.

RESULTS

We analyzed 416 patients; 325 survived and 91 were deceased. The postoperative chemotherapy rates (p < 0.001), and postoperative blood transfusion rates (p = 0.010) were significantly higher in the deceased group, while the preoperative albumin levels were significantly lower in the deceased group (p < 0.001). Infused colloid amount was higher in the deceased group of endometrial (p = 0.018) and ovarian cancers (p = 0.017).

CONCLUSIONS

Perioperative patient management for cancer surgery requires a multidisciplinary approach led by an anesthesiologist and surgeon. Any improvement in the duration of hospital stay, morbidity, or recovery rate depends on the success of the multidisciplinary team.

Survival outcomes and the prognostic significance of clinicopathological features in patients with endometrial clear cell carcinoma: a 35-year single-center retrospective study

BACKGROUND

To evaluate the oncological outcomes and the impact of clinicopathological factors on endometrial clear cell carcinoma (ECCC) outcomes.

METHODS

Medical records of patients with primary ECCC treated at our center between 1985 and December 2020 were reviewed. Overall survival (OS) and progression-free survival (PFS) were the endpoints. The Kaplan-Meier method and Cox regression analysis were used.

RESULTS

In total, 156 patients were included, of whom 59% and 41% had early- and advanced-stage ECCC, respectively. The median age of onset was 61 years, and 80.8% of the patients were postmenopausal. Ninety-two (59%) and 64 (41%) patients had pure ECCC and mixed endometrial carcinoma with clear cell carcinoma (CCC) components, respectively. Mixed pathological components, elevated cancer antigen 125 levels, positive lymphovascular space invasion, deep myometrial invasion, and malignant peritoneal washing cytology (PWC) were more frequently observed in the advanced stage. Thirty-nine patients (25%) experienced relapse and 32 patients (20.5%) died. The 5-year PFS and OS rates for the entire cohort were 72.6% and 79%, respectively. Multivariate analysis showed that advanced-stage disease and positive PWC significantly decreased PFS, while advanced-stage disease and older age (> 61 years) significantly decreased OS.

CONCLUSIONS

ECCC is a rare and aggressive type II endometrial carcinoma that is common in older women and patients with advanced-stage disease. Positive PWC was associated with decreased PFS, although its presence did not influence the stage. Positive PWC, and advanced stage and older age were independent negative prognostic factors.

Prognostic Factors for Survival in Patients with Carcinoma Endometrium

Francis. V. JamesObjective  The study aimed to see the clinical outcome and to identify prognostic factors for survival in patients with carcinoma endometrium. Methods  Patients registered at Regional Cancer Centre, Thiruvananthapuram, Kerala, India, with carcinoma endometrium from January 2009 to December 2013 were identified from hospital registry. Data regarding patient demographics, tumor characteristics, treatment schedules, and follow-up were collected using a structured proforma. Survival estimates were generated using the Kaplan-Meier method. Univariate analysis was done using chi-square and Fisher's exact tests. Multivariate analysis using the Cox regression model was performed to determine the impact of prognostic factors on outcome. The statistical analysis was done using SPSS software version 11. Results  The median follow-up of the 686 patients was 95 months (range 3-178 months).There were 432 stage 1 (63%), 100 stage II (14.6%), 108 stage III (15.7%), and 46 stage IV patients (6.7%). The 5-year overall survival was 89.2%. Prognostic factors for survival on univariate analysis were age 60 years or older, nonendometrioid histology, high-grade tumor, cervical stromal involvement, para-aortic node involvement, negative progesterone receptor expression, deep myometrial invasion advanced stage, surgery versus no surgery, serosal involvement, and ovarian and fallopian tube involvement. However, on multivariate analysis, age over 60 years, higher histological grade, advanced stage, and deep myometrial and parametrial invasion were associated with significantly poorer survival. Conclusion  We found that age over 60 years at presentation, higher grade, advanced stage, deep myometrial invasion, and parametrial invasion were associated with poorer survival.

Systematic Lymphadenectomy and Oncological Outcomes of Women With Apparent Early-Stage Clear Cell Carcinoma of the Endometrium: A Multi-Institutional Cohort Study

Objective

The survival value of systematic lymphadenectomy for endometrial cancer is ambiguous and controversial. The current study aimed to evaluate the long-term survival role of combined pelvic and para-aortic lymphadenectomy in patients with presumed early-stage clear cell carcinoma of the endometrium.

Methods

Patients in three Chinese teaching hospitals who presented between 2012 and 2017 with apparent early-stage clear cell carcinoma of the endometrium and underwent surgical staging were selected. Patients who did and did not undergo systematic lymphadenectomy were identified and clinicopathological characteristics were compared. Disease-free survival and overall survival were evaluated following the generation of the Kaplan-Meier curves and the comparison using the log-rank test. A Cox proportional hazards model was employed to control for confounders.

Results

A total of 244 patients underwent systematic lymphadenectomy and 89 did not receive lymph node dissection. The demographic and baseline data were comparable between the two groups. The rate of disease-free survival at 5 years was 64.10% in patients who underwent systematic lymphadenectomy and 45.05% in patients who did not undergo lymphadenectomy. Patients who underwent systematic lymphadenectomy had better disease-free survival than those who did not receive lymphadenectomy (HR, 0.54. 95% CI, 0.38-0.76. P=0.000). The rate of 5-year overall survival was 68.87% in the lymphadenectomy group and 53.33% in patients who did not undergo systematic lymphadenectomy. Systematic lymphadenectomy was also associated with improved 5-year overall survival for women with presumed early-stage clear cell carcinoma of the endometrium (HR, 0.58. 95% CI, 0.39-0.85. P=0.005). After adjusting for confounders, systematic lymphadenectomy was still independently associated with improved disease-free survival and overall survival.

Conclusion

Patients with apparent early-stage clear cell carcinoma of the endometrium who underwent systematic lymphadenectomy had better long-term survival than those who did not undergo systematic lymphadenectomy.
