Abstract
PURPOSE OF REVIEW Early menopause represents a relevant clinical issue for women. Nevertheless, this issue should be balanced with the risks of ovarian metastasis, ovarian recurrence, and the risk of recurrence in hormone-sensitive gynecological cancers. The purpose of this review was to provide an overview on current indications and techniques of ovarian preservation in patients with gynecological cancers. RECENT FINDINGS The potential discussion about ovarian conservation could be proposed to patients with FIGO-stage IA grade 1-2 endometrioid endometrial cancer aged 40 years or less, FIGO-stage IB1-IB2 node-negative cervical cancer with squamous cell carcinoma and HPV-associated adenocarcinoma, FIGO-stage IA-IC grade 1-2 serous, endometrioid, mucinous expansile pattern ovarian cancer, any stage germ cell ovarian tumors, and FIGO-stage IA sex cord-stromal tumors. Technique to perform ovarian transposition in cervix cancer is also reported. SUMMARY Ovarian conservation is a surgical approach that involves preserving one or both ovaries during the treatment of gynecologic cancers. This approach has gained popularity in recent years, as it offers several benefits to the patient, including the preservation of hormonal function and fertility. The decision to perform ovarian conservation depends on several factors, such as the stage and type of cancer, the patient's age, fertility desire, and should be carefully discussed with patients.

EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:461-467. [PMID: 36064632 DOI: 10.1016/j.ejso.2022.08.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Accepted: 08/23/2022] [Indexed: 10/15/2022]
Abstract
OBJECTIVE To examine characteristics and survival of patients who developed secondary ovarian cancer after external beam radiotherapy (EBRT) for a prior nonovarian pelvic malignancy. METHODS This is a population-based retrospective cohort study, querying the Surveillance, Epidemiology, and End Result program from 1975 to 2016. 167,269 women who received EBRT for 7 malignancies (anus, rectum, bladder, cervix, uterus, vulva, or vagina) were examined to identify subsequent secondary ovarian cancer diagnosis after EBRT. Then, within the ovarian cancer cohort (n = 147,618), characteristics and survival of patients with secondary ovarian cancer after EBRT were compared to those with ovarian cancer who did not receive prior EBRT. RESULTS Following EBRT for a pelvic malignancy, 215 (1.3 per 1000) patients developed secondary ovarian cancer. Among those, the most frequent prior malignancy was cervical cancer (45.6%), followed by rectal cancer (20.9%). The median time from prior EBRT to secondary ovarian cancer was 8.8 years (interquartile range, 2.8-14.5). In multivariable analysis, patients with secondary ovarian cancer after EBRT were more likely to be older, and have a recent year of diagnosis, but less likely to have early-disease compared to ovarian cancer patients without prior EBRT (all, P < 0.05). In weighted model, patients with secondary ovarian cancer after EBRT had decreased overall survival compared to those with ovarian cancer without prior EBRT (5-year rates, 19.6% versus 39.9%, hazard ratio 1.62, 95% confidence interval 1.43-1.85). Similar association was observed in ages <70, ≥70, White, non-White, early-disease, and advanced-disease in sensitivity analyses. CONCLUSION Radiotherapy-related secondary ovarian cancer may be associated with decreased overall survival.

Abstract
Background The time interval rules and survival outcomes of individuals with synchronous and metachronous breast cancer (BC) and ovarian cancer (OC) were examined in this retrospective population-based investigation. Methods The National Cancer Institute's Surveillance, Epidemiology, and End Results database was used to create a cohort of people diagnosed with BC and OC between 1973 and 2015. Patients were separated into three groups: those with main BC followed by primary OC (group 1), those with synchronous primary breast and ovarian cancer (group 2), and those with OC prior to BC (group 3). The Kaplan-Meier technique was used to assess overall survival (OS) and cancer-specific survival (CSS). Results A total of 4,975 patients were identified: 2,929 patients in group 1, 680 patients in group 2, and 1,366 patients in group 3. The average duration between these tumors was 60 months (range 0-499). Approximately 50% of second primary cancer cases occurred during the first 60 months of the first primary cancer diagnosis, and more than 70% occurred within the first 120 months. The median survival time for 4,975 individuals was 140 months. Group 2 had the smallest median OS (35 months), whereas group 3 had the longest (45 months) (239 months). Conclusions The majority of second primary cancer cases occurred during the first 120 months following the diagnosis of the first original malignancy. Individuals who had primary OC prior to BC had better prognoses, whereas patients who had synchronous BC and OC had worse prognoses.

Trends and characteristics of ovarian conservation at hysterectomy for young women with cervical cancer. Eur J Obstet Gynecol Reprod Biol 2022; 273:59-64. [PMID: 35487095 DOI: 10.1016/j.ejogrb.2022.04.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 04/02/2022] [Accepted: 04/11/2022] [Indexed: 11/04/2022]
Abstract
OBJECTIVE The association between early surgical menopause and increased mortality has been well demonstrated. Prior studies have also demonstrated that ovarian conservation is not associated with worse oncologic outcomes in early-stage cervical cancer. This study examined the contemporary trends and characteristics of ovarian conservation at time of hysterectomy in young women with cervical cancer. METHODS This is a retrospective cohort study examining the National Inpatient Sample. The study population was 4900 women aged ≤50 years with cervical cancer who had hysterectomy-based surgical treatment from 10/2015 to 12/2018. The exposure allocation was the adnexal procedure status (ovarian conservation versus oophorectomy). The main outcome measures were temporal trends of ovarian conservation over time and per patient age. Multivariable binary logistic regression model was fitted to identify independent characteristics associated with ovarian conservation. A classification-tree was constructed by recursive partitioning analysis to examine the utilization patterns of ovarian conservation. RESULTS A total of 2,940 (60.0%) women underwent ovarian conservation at hysterectomy. Ovarian conservation rates remained stable until age 37 years, ranging from 82.5% to 77.9% (P = 0.502), after which time the rate sharply and significantly decreased by 7.4% (95% confidence interval 5.4-9.3, P < 0.001) in one-year age increments from 77.9% at age 37 years to 28.7% at age 50 years. The rate of ovarian conservation increased from 54.7% in Q4/2015 to 64.4% in Q4/2018 (P = 0.002). In multivariable analysis, recent surgery remained an independent factor for ovarian conservation (adjusted-odds ratio per year-quarter 1.04, 95% confidence interval 1.03-1.06). A classification-tree model identified 24 unique patterns of ovarian conservation based on patient factor (age, race/ethnicity, primary expected payer, and year of surgery), surgical factor (minimally invasive hysterectomy), and facility factor (hospital bed capacity and region), ranging from <20% to 90% (absolute percentage difference, >80%). CONCLUSION Increasing rates of ovarian conservation at the time of hysterectomy in women undergoing surgical management of cervical cancer is encouraging; however, the marked decrease noted in patients in their mid-30s as well as substantial variability in ovarian conservation based on patient, surgical, and hospital factors are striking and warrant further consideration in clinical practice guidelines.

Abstract
The concept of neurotrophic factor tyrosine kinase receptor (NTRK) fusion tumor has emerged in recent years. Moreover, NTRK fusion is unusual in common tumors but can often be identified in rare tumors. The NTRK fusion cervical or uterine tumors are mainly recognized through case reports due to their extremely low incidence. In this study, we reported a new case of EML4–NTRK3 fusion cervical sarcoma to enhance its recognition. To the best of our knowledge, this is the first case from a Chinese institution. We also conducted a literature review, in which a total of 19 cases of NTRK fusion cervical tumors and 4 cases of uterine tumors were retrieved. We summarized the clinicopathological features, treatment methods, and prognosis of these cases. Based on available information, we observed that surgery and complete excision, if possible, are still the primary modes of therapy. In addition, an increasing number of studies have shown that tropomyosin receptor kinases (TRK) inhibitors can improve the prognosis of cancer patients with NTRK gene fusion, which gives a silver lining for patients with metastatic lesions. We found that age and mitotic rate may be associated with recurrence or metastasis by univariate survival analysis. To draw more convincing conclusions, there is a need to establish an international database of rare cases and aggregate these sporadic cases.

Abstract
Objective To identify the incidence of ovarian metastasis and the impact of ovarian preservation on oncological outcomes for early-stage adenocarcinoma and adenosquamous cervical cancer. Methods 281 patients with stages IA2-IB1 adenocarcinoma and adenosquamous cervical cancer who underwent radical hysterectomy with pelvic lymphadenectomy (RHND) were included in the study. The incidence of ovarian metastasis was evaluated from 173 patients who underwent oophorectomy during RHND. Subgroup analysis was performed for patients less than 50 years (196 of 281 patients) who were classified into two groups, ovarian preservation and nonovarian preservation groups. 5-year recurrence-free survival (5-yr RFS) and 5-year overall survival (5-yr OS) were evaluated and compared between these groups. Results There was no evidence of ovarian metastasis, synchronous ovarian cancer, or ovarian recurrence during follow-up. In patients less than 50 years of age, there were no statistically significant differences in the 5-yr RFS (P = 0.363), or 5-yr OS (P = 0.974) between the ovarian preservation and nonovarian preservation groups. In Kaplan-Meier analysis, the ovarian preservation group seemed to have a slightly better OS in long-term follow-up (after 15 years); however, the difference was not statistically significant. Conclusions Ovarian preservation was safe in adenocarcinoma and adenosquamous cervical cancer stages IA2-B1. However, the impact of ovarian preservation on oncological outcomes needs to be further investigated.

Abstract
OBJECTIVE To describe how population-based statistics for rare epithelial ovarian cancers are evolving. METHODS This is a retrospective observational study examining the Surveillance, Epidemiology, and End Results Program from 1988 to 2016. Overall survival (OS) of clear cell (OCCC), mucinous (MOC), and low-grade serous (LGSOC) ovarian cancers were compared to high-grade serous ovarian cancer (HGSOC) by fitting a propensity score matching. RESULTS Among 113,365 ovarian malignancies, 5780 OCCCs (5.1%), 7561 MOCs (6.7%), and 2021 LGSOCs (1.8%) were compared to 38,199 HGSOCs. OCCCs and MOCs were more likely to be diagnosed with stage I disease compared to HGSOC (57.0-59.5% versus 8.6%, P<0.001). For early-stage disease, OCCC (hazard ratio [HR] 0.91, 95% confidence interval [CI] 0.82-1.01) and MOC (HR 0.94, 95%CI 0.85-1.04) had similar OS to HGSOC whereas LGSOC had superior OS (HR 0.93, 95%CI 0.89-0.97) versus HGSOC. Conversely, for advanced-stage disease, OCCC (HR 1.42, 95%CI 1.32-1.53) and MOC (HR 1.11, 95%CI 1.09-1.13) had poorer OS whereas LGSOC (HR 0.86, 95%CI 0.84-0.89) had superior OS compared to HGSOC. OCCC (HR range, 1.92-2.45) and MOC (HR range, 1.73-2.22) had particularly poorer OS in the first three years following diagnosis compared to HGSOC. Population-level statistics for advanced-stage disease showed that 5-year OS rates have increased in HGSOC (16.9% to 36.8%, P<0.001) and LGSOC (50.8% to 66.4%, P=0.010); but remain unchanged for OCCC (21.0% to 28.2%, P=0.174) and MOC (21.4% to 16.5%, P=0.102). CONCLUSION OCCC, MOC, and LGSOC comprise 2-7% of ovarian malignancies, have distinct characteristics and survival compared to HGSOC. While these rare tumors have a favorable to comparable prognosis in early-stage disease, disproportionally poor survival in advanced-stage OCCC and MOC highlights the need for further research into novel treatment strategies.

Abstract
Objective To examine the association between tumor grade and survival for women with squamous cervical cancer. Methods This retrospective observational study utilized the Surveillance, Epidemiology, and End Result program data between 1983 and 2013 to examine women with squamous cervical cancer with known tumor differentiation grade. Multivariable analyses were performed to assess independent associations between tumor differentiation grade and survival. Results A total of 31,536 women were identified including 15,175 (48.1%) with grade 3 tumors, 14,084 (44.7%) with grade 2 neoplasms and 2,277 (7.2%) with grade 1 tumors. Higher tumor grade was significantly associated with older age, higher stage disease, larger tumor size, and lymph node metastasis (all, p<0.001). In a multivariable analysis, grade 2 tumors (adjusted-hazard ratio [HR]=1.21; p<0.001) and grade 3 tumors (adjusted-HR=1.45; p<0.001) were independently associated with decreased cause-specific survival (CSS) compared to grade 1 tumors. Among the 7,429 women with stage II–III disease who received radiotherapy without surgical treatment, grade 3 tumors were independently associated with decreased CSS compared to grade 2 tumors (adjusted-HR=1.16; p<0.001). Among 4,045 women with node-negative stage I disease and tumor size ≤4 cm who underwent surgical treatment without radiotherapy, grade 2 tumors (adjusted-HR=2.54; p=0.028) and grade 3 tumors (adjusted-HR=4.48; p<0.001) were independently associated with decreased CSS compared to grade 1 tumors. Conclusion Our study suggests that tumor differentiation grade may be a prognostic factor in women with squamous cervical cancer, particularly in early-stage disease. Higher tumor grade was associated with poorer survival.

METHODS This retrospective observational study examined the Surveillance, Epidemiology, End Results Program between 1973 and 2013.

Survival was compared between metachronous and non-metachronous uterine malignancies according to tumor factors. RESULTS The 10- and 20-year cumulative incidences of metachronous uterine malignancy were 0.6% and 1.2%, respectively. When compared to non-metachronous uterine malignancy, metachronous tumor were more likely to be non-endometrioid and advanced-stage (both, P < 0.001). As a whole cohort, metachronous uterine malignancy was significantly associated with decreased overall survival (OS) compared to non-metachronous tumors (hazard ratio [HR] 4.22, P < 0.001). OS was significantly worse in metachronous compared to non-metachronous malignancies, although the magnitude of statistical significance was greater for endometrioid tumors (HRs for endometrioid versus non-endometrioid: 6.17 versus 1.92). For grade 1-2 endometrial cancer, metachronous cases had significantly decreased OS compared to non-metachronous cases, a larger difference than that seen in higher grade tumors (HRs for grade 1-2 versus 3: 7.79 versus 2.15). Similarly, in early-stage endometrial cancer, metachronous cases had significantly decreased OS, with a greater HR compared to advanced-stage disease (HRs for stage I-II versus III-IV: 5.29 versus 2.29). CONCLUSION Radiotherapy-associated metachronous uterine malignancy after cervical cancer is rare but commonly presents with aggressive tumor characteristics. The impact on survival is considerably high when metachronous uterine malignancy is endometrioid, low-grade, and early-stage.

Abstract
OBJECTIVE To examine incidences and risk factors for metachronous vulvar, vaginal, and anal malignancies after a cervical cancer diagnosis. METHODS This is a retrospective study examining data from the Surveillance, Epidemiology, and End Result Program between 1973 and 2013. Cumulative incidences of vulvar, vaginal, and anal cancers after the diagnosis of cervical cancer were assessed (n = 79,050). Multivariable analysis was performed to determine independent risk factors for these metachronous cancers. RESULTS Vaginal cancer (20-year cumulative incidence, 0.57%) was the most common type of metachronous malignancy, followed by vulvar cancer (0.33%), and anal cancer (0.16%, P < 0.001). Median time to diagnosis was 5.4 years for vaginal cancer, 6.5 years for vulvar cancer, and 13.5 years for anal cancer. On multivariable analysis, metachronous vulvar cancer was associated with older age (hazard ratio [HR] per year 1.04, 95% confidence interval [CI] 1.02-1.05, P < 0.001), squamous histology (HR 2.64, 95%CI 1.38-5.05, P = 0.003), and radiotherapy use (HR 2.52, 95%CI 1.66-3.84, P < 0.001); metachronous vaginal cancer was associated with older age (HR per year 1.03, 95%CI 1.02-1.04, P < 0.001) and Black race (HR 1.73, 95%CI 1.20-2.48, P = 0.003); and metachronous anal cancer was associated with older age (HR 1.03, 95%CI 1.01-1.05, P = 0.017). Overall survival of metachronous cancer was poor (5-year rates: 46.3% for vulvar, 43.0% for vaginal, and 47.5% for anal cancer, respectively). CONCLUSION Although rare, the rate of ano-genital cancers continues to increase over time after a cervical cancer diagnosis. Long-term follow-up and surveillance after cervical cancer treatment is therefore reasonable to detect these metachronous malignancies, particularly in those with risk factors.

Abstract
This retrospective observational study examined trends, characteristics, and survival of women with synchronous endometrial and ovarian cancer (SEOC) in the Surveillance, Epidemiology, and End Results Program between 1973 and 2013. Among 235,454 women with primary endometrial cancer, synchronous ovarian cancer was seen in 4,082 (1.7%) women with the proportion being decreased from 2.0% to 1.6% between 1983 and 2013 (P=0.049); and the proportion of concurrent endometrioid tumors in the two cancer sites has increased from 24.2% to 49.9% among SEOC women (P<0.001). When compared to endometrial cancer without synchronous ovarian cancer, endometrioid histology in the two cancer sites was associated with improved cause-specific survival while non-endometrioid histology in the ovarian cancer was associated with decreased cause-specific survival (adjusted-P<0.01). Among 110,063 women with primary epithelial ovarian cancer, synchronous endometrial cancer was seen in 3,940 (3.6%) women with the proportion being increased from 2.2% to 4.4% between 1973 and 2013 (P<0.001); and the proportion of concurrent endometrioid tumors in the two cancer sites had increased from 24.3% to 50.2% among SEOC women (P<0.001). When compared to primary epithelial ovarian cancer without synchronous endometrial cancer, SEOC was associated with better cause-specific survival if ovarian cancer is endometrioid type or if endometrial cancer is endometrioid type (adjusted-P<0.001). Across the two cohorts, the proportion of SEOC reached to the peak in the late-40 years of age and then decreased significantly (P<0.001). In conclusion, our study suggests that synchronous ovarian cancer has decreased among endometrial cancer whereas synchronous endometrial cancer has increased among epithelial ovarian cancer.

Abstract
OBJECTIVE To examine the trends and survival for women with early-stage epithelial ovarian cancer who underwent adequate lymphadenectomy during surgical treatment. METHODS This is a retrospective observational study examining the Surveillance, Epidemiology, End Results program between 1988 and 2013. We evaluated 21,537 cases of stage I-II epithelial ovarian cancer including serous (n=7,466), clear cell (n=6,903), mucinous (n=4,066), and endometrioid (n=3,102) histology. A time-trend analysis of the proportion of patients who underwent adequate pelvic lymphadenectomy (≥8 per Gynecologic Oncology Group [GOG] criteria, ≥12 per Collaborative Group Report [CGR] criteria for bladder cancer, and >22 per Mayo criteria for endometrial cancer) and a survival analysis associated with adequate pelvic lymphadenectomy were performed. RESULTS There were significant increases in the proportion of women who underwent adequate lymphadenectomy: GOG criteria 3.6% to 28.6% (1988-2010); CGR criteria 2.4% to 22.4% (1988-2013); and Mayo criteria 0.7% to 9.5% (1988-2013) (all, p<0.05). On multivariable analysis, adequate lymphadenectomy was independently associated with improved cause-specific survival compared to inadequate lymphadenectomy: GOG criteria, adjusted-hazard ratio (HR)=0.75, CGR criteria, adjusted-HR=0.77, and Mayo criteria, adjusted-HR=0.85 (all, p<0.05). Compared to inadequate lymphadenectomy, adequate lymphadenectomy was significantly associated with improved cause-specific survival for serous (HR range=0.67-0.73), endometrioid (HR range=0.59-0.61), and clear cell types (HR range=0.66-0.73) (all, p<0.05) but not in mucinous type (HR range=0.80-0.91; p>0.05). CONCLUSION Quality of lymphadenectomy during the surgical treatment for early-stage epithelial ovarian cancer has significantly improved. Adequate lymphadenectomy is associated with a 15%-25% reduction in ovarian cancer mortality compared to inadequate lymphadenectomy.

Abstract
This study seeks to identify risk factors associated with ovarian metastasis and to characterize a population with minimum risk of ovarian metastasis in young women with stage IB-IIB cervical cancer. This was a nation-wide multicenter retrospective study in Japan examining consecutive cases of surgically-treated women with clinical stage IB-IIB cervical cancer who had oophorectomy at radical hysterectomy (n = 5,697). Multivariable analysis was performed to identify independent risk factors for ovarian metastasis. Ovarian metastasis was seen in 70 (1.2%, 95% confidence interval 0.9-1.5) cases. In the entire cohort, adenocarcinoma, lympho-vascular space invasion, uterine corpus tumor invasion, and pelvic/para-aortic nodal metastases remained independent risk factors for ovarian metastasis (all, adjusted-p < 0.05). In a sensitivity analysis of 3,165 women aged <50 years (ovarian metastasis, 1.0%), adenocarcinoma, parametrial tumor involvement, uterine corpus tumor involvement, and pelvic/para-aortic nodal metastases remained independent risk factors for ovarian metastasis (all, adjusted-P < 0.05). In the absence of these five risk factors (representing 46.1% of women aged <50 years), the incidence of ovarian metastasis was 0.14%. With the presence of adenocarcinoma alone (representing 18.9% of women aged <50 years), the incidence of ovarian metastasis was 0.17% and was not associated with increased risk of ovarian metastasis compared to the subgroup without any risk factors (p = 0.87). In conclusion, nearly two thirds of women aged <50 years with clinical stage IB-IIB cervical cancer had no risk factor for ovarian metastasis or had adenocarcinoma alone: these subgroups had ovarian metastasis rates of around 0.1% and may be a candidate population for ovarian conservation at surgical treatment.

Abstract
OBJECTIVE Synchronous endometrial and ovarian cancer with endometrioid histology at two cancer sites typically presents with early-stage disease and is thought to have a good prognosis. We examined the survival of women with early-stage endometrioid endometrial cancer who had synchronous early-stage endometrioid ovarian cancer. METHODS This is a retrospective case-control study examining the Surveillance, Epidemiology, and End Result Program between 1973 and 2013. Survival of women with stage I endometrioid endometrial cancer with stage I endometrioid ovarian cancer (n=839) were compared to women with stage I endometrioid endometrial cancer without synchronous ovarian cancer (n=123,692) after propensity score matching. RESULTS Women with synchronous stage I endometrioid ovarian cancer were more likely to be diagnosed recently, be younger, have stage IA disease, grade 1 tumors, to have undergone lymphadenectomy, and were less likely to receive radiotherapy compared to those without synchronous ovarian cancer (all, P<0.001). In a propensity score matched model, the presence of synchronous ovarian cancer was not associated with endometrial cancer-specific survival (10-year rates 96.0% versus 95.3%, P=0.97) or overall survival (85.6% versus 87.2%, P=0.10). Among tumors with concordant grades at the two cancer sites, survival was similar regardless of presence of synchronous ovarian tumors (grade 1 tumors, 10-year rate for overall survival, 88.2% versus 89.1%, P=0.40; and grade 2 tumors, 84.0% versus 85.8%, P=0.78). CONCLUSION Women with stage I endometrioid endometrial cancer with synchronous stage I endometrioid ovarian cancer have a survival outcome similar to those with stage I endometrioid endometrial cancer without synchronous ovarian cancer.
