Risk of metachronous ovarian cancer after ovarian conservation in young women with stage I cervical cancer.

ABSTRACT: While there is an increasing trend of ovarian conservation at the time of surgical treatment for young women with stage I cervical cancer, the risk for subsequent ovarian cancer after ovarian conservation has not been well studied.We sought to examine the incidence of and risk factors for metachronous ovarian cancer among young women with stage I cervical cancer who had ovarian conservation at the time of hysterectomy.The Surveillance, Epidemiology, and End Results Program was used to identify women aged <50 years who underwent hysterectomy with ovarian conservation for stage I cervical cancer from 1983 through 2013 (n = 4365). Time-dependent analysis was performed for ovarian cancer risk after cervical cancer diagnosis.Mean age at cervical cancer diagnosis was 37 years, and the majority of patients had stage IA disease (68.2%) and squamous histology (72.9%). Median follow-up time was 10.8 years, and there were 13 women who developed metachronous ovarian cancer. The 10- and 20-year cumulative incidences of metachronous ovarian cancer were 0.2% (95% confidence interval, 0.1-0.4) and 0.5% (95% confidence interval, 0.2-0.8), respectively. Mean age at the time of diagnosis of metachronous ovarian cancer was 47.5 years, and stage III-IV disease was seen in 55.6%. Age (?45 vs <45 years, hazard ratio, 4.22; 95% confidence interval, 1.16-15.4; P = .018), ethnicity (non-white vs white, hazard ratio, 4.29; 95% confidence interval, 1.31-14.0; P = .009), cervical cancer histology (adenocarcinoma or adenosquamous vs squamous, hazard ratio, 3.50; 95% confidence interval, 1.17-10.5; P = .028), and adjuvant radiotherapy use (yes vs no, hazard ratio, 3.69; 95% confidence interval, 1.01-13.4; P = .034) were significantly associated with metachronous ovarian cancer risk. The presence of multiple risk factors was associated with a significantly increased risk of metachronous ovarian cancer compared to the no risk factor group: 1 risk factor (hazard ratio range, 2.96-8.43), 2 risk factors (hazard ratio range, 16.6-31.0), and 3-4 risk factors (hazard ratio range, 62.3-109), respectively.Metachronous ovarian cancer risk after ovarian conservation for women with stage I cervical cancer is <1%. Older age, non-white ethnicity, adenocarcinoma or adenosquamous histology, and adjuvant radiotherapy may be associated with an increased metachronous ovarian cancer risk.

Project description:ObjectiveTo identify predictors of ovarian conservation at hysterectomy and to examine the association of ovarian conservation and survival of young women with early-stage cervical cancer.MethodsThis is a retrospective cohort study using the Surveillance, Epidemiology, and End Results Program to identify hysterectomy-based surgically treated patients with stage I cervical cancer diagnosed between 1983 and 2012 (N=16,511). Multivariable models were used to identify independent factors associated with ovarian conservation. Among the subgroup of 9,419 women younger than 50 years of age with stage I disease, survival outcomes and causes of death were examined for 3,908 (41.5%) women who underwent ovarian conservation at hysterectomy without radiotherapy.ResultsOn multivariable analysis, age younger than 50 years, stage IA disease, and squamous histology were independent factors associated with ovarian conservation (all, P<.001). Among 5,526 women younger than 50 years of age with stage IA disease who underwent hysterectomy without radiotherapy, overall survival was significantly higher in patients undergoing ovarian conservation than in those undergoing oophorectomy (20-year rate, 93.5% compared with 86.8%, P<.001); cervical cancer-specific survival was similar between the patients who underwent ovarian conservation and those who underwent oophorectomy (98.8% compared with 97.8%, P=.12). On multivariable analysis, ovarian conservation remained an independent prognostic factor for improved overall survival (adjusted hazard ratio 0.63, 95% confidence interval [CI] 0.49-0.82, P=.001) and was independently associated with lower cumulative risks of death resulting from cardiovascular disease (20-year cumulative rate, 1.2% compared with 3.3%, adjusted hazard ratio 0.47, 95% CI 0.26-0.86, P=.014) and other chronic disease (0.5% compared with 1.4%, adjusted hazard ratio 0.24, 95% CI 0.09-0.65, P=.005) compared with oophorectomy. Both cervical cancer-specific survival (20-year rate, 93.1% compared with 92.0%, P=.37) and overall survival (86.7% compared with 84.6%, P=.12) were similar between ovarian conservation and oophorectomy among 3,893 women younger than 50 years of age with stage IB disease who underwent hysterectomy without radiotherapy.ConclusionAmong young women with stage IA cervical cancer, ovarian conservation at hysterectomy is associated with decreased all-cause mortality including death resulting from cardiovascular disease and other chronic diseases.

Project description:ObjectiveTo characterize contributing factors for ovarian conservation during surgical treatment for endometrial cancer and to examine the association of ovarian conservation on survival of young women with early-stage, low-grade tumors.MethodsThis was a population-based study using the Surveillance, Epidemiology, and End Results program to identify surgically treated stage I type I (grade 1-2 endometrioid histology) endometrial cancer cases diagnosed between 1983 and 2012 (N=86,005). Multivariable models were used to identify independent factors for ovarian conservation. Survival outcomes and cause of death were examined for women aged younger than 50 with stage I type I endometrial cancer who underwent ovarian conservation (1,242 among 12,860 women [9.7%]).ResultsOn multivariable analysis, age younger than 50 years, grade 1 endometrioid histology, and tumor size 2.0 cm or less were noted to be independent factors for ovarian conservation (all, P<.001). For 9,110 women aged younger than 50 years with stage I grade 1 tumors, cause-specific survival was similar between ovarian conservation and oophorectomy cases (20-year rates 98.9% compared with 97.7%, P=.31), whereas overall survival was significantly higher in ovarian conservation cases than oophorectomy cases (88.8% compared with 82.0%, P=.011). On multivariable analysis, ovarian conservation remained an independent prognostic factor for improved overall survival (adjusted hazard ratio 0.73, 95% confidence interval [CI] 0.54-0.98, P=.036) and was independently associated with a lower cumulative risk of death resulting from cardiovascular disease compared with oophorectomy (20-year rates, 2.3% compared with 3.7%, adjusted hazard ratio 0.40, 95% CI 0.17-0.91, P=.029). Contrary, cause-specific survival (20-year rates 94.6% compared with 96.1%, P=.68) and overall survival (81.0% compared with 80.6%, P=.91) were similar between ovarian conservation and oophorectomy among 3,750 women aged younger than 50 years with stage I grade 2 tumors.ConclusionOvarian conservation is performed in less than 10% of young women with stage I type I endometrial cancer. Ovarian conservation is associated with decreased mortality in young women with stage I grade 1 tumors.

Project description:ObjectiveTo examine the association between ovarian conservation and oncologic outcome in surgically-treated young women with early-stage, low-grade endometrial cancer.MethodsThis multicenter retrospective study examined women aged <50 with stage I grade 1-2 endometrioid endometrial cancer who underwent primary surgery with hysterectomy from 2000 to 2014 (US cohort n = 1196, and Japan cohort n = 495). Recurrence patterns, survival, and the presence of a metachronous secondary malignancy were assessed based on ovarian conservation versus oophorectomy.ResultsDuring the study period, the ovarian conservation rate significantly increased in the US cohort from 5.4% to 16.4% (P = 0.020) whereas the rate was unchanged in the Japan cohort (6.3-8.7%, P = 0.787). In the US cohort, ovarian conservation was not associated with disease-free survival (hazard ratio [HR] 0.829, 95% confidence interval [CI] 0.188-3.663, P = 0.805), overall survival (HR not estimated, P = 0.981), or metachronous secondary malignancy (HR 1.787, 95% CI 0.603-5.295, P = 0.295). In the Japan cohort, ovarian conservation was associated with decreased disease-free survival (HR 5.214, 95% CI 1.557-17.464, P = 0.007) and an increased risk of a metachronous secondary malignancy, particularly ovarian cancer (HR 7.119, 95% CI 1.349-37.554, P = 0.021), but was not associated with overall survival (HR not estimated, P = 0.987). Ovarian recurrence or metachronous secondary ovarian cancer occurred after a median time of 5.9 years, and all cases were salvaged.ConclusionOur study suggests that adoption of ovarian conservation in young women with early-stage low-grade endometrial cancer varies by population. Ovarian conservation for young women with early-stage, low-grade endometrial cancer may be potentially associated with increased risks of ovarian recurrence or metachronous secondary ovarian cancer in certain populations; nevertheless, ovarian conservation did not negatively impact overall survival.

Project description:ObjectiveTo profile patient characteristics associated with and outcomes of ovarian conservation at the time of hysterectomy in young women with minimal-risk endometrial cancer.MethodsA population-based retrospective analysis of the Nationwide Inpatient Sample between 2007 and 2015 was performed. Women aged <50 with minimal-risk endometrial cancer who had ovarian conservation (n = 2314) were compared to those who had oophorectomy (n = 8191). A classification-tree model with recursive partitioning analysis was constructed to examine patterns of ovarian conservation. Propensity score matching was performed and length of stay and perioperative complications were compared. Two validation cohorts were also analyzed in a similar fashion (benign gynecologic disease and cervical cancer).ResultsThere were nine distinct patterns of patient characteristics identified, and ovarian conservation rates ranged from 11.7% (women aged 40-49 who underwent abdominal hysterectomy at an urban teaching hospital) to 60.5% (non-obese women aged <40 with median household income ≥$63,000) (absolute difference, 48.8%, 95% confidence interval 39.9-57.7; P < 0.001). After propensity score matching, ovarian conservation was significantly associated with a decreased likelihood of hospitalization >2 days (relative risk reduction, 16.7%, P < 0.001). Rates of surgical complications were not different between the two groups (8.2% versus 8.3%, P = 0.91). In the benign gynecologic disease and cervical cancer cohorts, ovarian conservation was also associated with decreased length of hospitalization (all, P < 0.05).ConclusionThere is substantial variability in the utilization of ovarian conservation in young women with minimal-risk endometrial cancer based on patient, surgical, and hospital factors. Our study suggests that guidelines for ovarian conservation in this population would be helpful for improving patient selection and rates of ovarian conservation.

Project description:BackgroundOvarian metastasis following radical gastrectomy, also known as metachronous ovarian metastasis (MOM), pose a significant threat to the long-term survival of female gastric cancer (GC) patients. However, a mechanism to identify and characterize operated patients at high risk of developing MOM remains unknown. This retrospective study aimed to identify risk factors for the occurrence of MOM based on the profiling of clinicopathological parameters and expression of sex hormone receptors (SHR) of operated GC patients with and without ovarian relapse.MethodsThe clinicopathological data of 1,055 female GC patients from two medical centers who underwent surgery between January 2011 and December 2015 were reviewed. A total of 378 patients with and without the occurrence of MOM met the eligibility criteria, including the availability of medical records, adequacy of lymph node dissection, completeness of clinicopathological data, sufficient follow-up time, and no administration of neoadjuvant chemotherapy were selected for further analysis. Expressions of estrogen receptor alpha (ERα), estrogen receptor beta (ERβ), and progesterone receptor (PR) were detected by immunohistochemical staining on the surgical specimens of patients, and retrospective statistical analyses identified independent risk factors for the occurrence of MOM. A risk prediction model in the format of a polygenic hazard score (PHS) for the occurrence of MOM was established by introducing and modifying the previously validated polygenic risk score (PRS)/PHS.ResultsA Cox regression-based multivariate analysis identified premenopausal with an HR of 3.15 (95% CI, 1.66-5.98), more advanced pathological T stage with an HR of 3.79 (95% CI, 2.14-6.69), more advanced pathological N stage with an HR of 1.85 (95% CI, 1.35-2.54), and negative expression of ERβ with an HR of 0.33 (95% CI, 0.15-0.7) as independent risk factors for the occurrence of MOM (P<0.01). Accordingly, a PHS for the occurrence of MOM was established, with 1-, 2-, and 3-year ovarian relapse rates for the high-risk group estimated at 17.8%, 33.7%, and 46.2%, respectively.ConclusionsPremenopausal status, depth of tumor invasion, number of positive lymph nodes, and negative expression of ERβ were independent factors for the occurrence of MOM. More frequent follow-up examinations are recommended to provide timely diagnosis and medical intervention.
