COVID-19 outcomes of patients with gynecologic cancer in New York City.

BACKGROUND: New York City (NYC) is the epicenter of severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019 [COVID-19]) in the United States. Clinical characteristics and outcomes of vulnerable populations, such as those with gynecologic cancer who develop COVID-19 infections, is limited. METHODS: Patients from 6 NYC-area hospital systems with known gynecologic cancer and a COVID-19 diagnosis were identified. Demographic and clinical outcome data were abstracted through a review of electronic medical records. RESULTS: Records for 121 patients with gynecologic cancer and COVID-19 were abstracted; the median age at the COVID-19 diagnosis was 64.0 years (interquartile range, 51.0-73.0 years). Sixty-six of the 121 patients (54.5%) required hospitalization; among the hospitalized patients, 45 (68.2%) required respiratory intervention, 20 (30.3%) were admitted to the intensive care unit, and 9 (13.6%) underwent invasive mechanical ventilation. Seventeen patients (14.0%) died of COVID-19 complications. No patient requiring mechanical ventilation survived. On multivariable analysis, hospitalization was associated with an age ≥64 years (risk ratio [RR], 1.73; 95% confidence interval [CI], 1.18-2.51), African American race (RR, 1.56; 95% CI, 1.13-2.15), and 3 or more comorbidities (RR, 1.43; 95% CI, 1.03-1.98). Only recent immunotherapy use (RR, 3.49; 95% CI, 1.08-11.27) was associated with death due to COVID-19 on multivariable analysis; chemotherapy treatment and recent major surgery were not predictive of COVID-19 severity or mortality. CONCLUSIONS: The case fatality rate among gynecologic oncology patients with a COVID-19 infection is 14.0%. Recent immunotherapy use is associated with an increased risk of mortality related to COVID-19 infection. LAY SUMMARY: The case fatality rate among gynecologic oncology patients with a coronavirus disease 2019 (COVID-19) infection is 14.0%; there is no association between cytotoxic chemotherapy and cancer-directed surgery and COVID-19 severity or death. As such, patients can be counseled regarding the safety of continued anticancer treatments during the pandemic. This is important because the ability to continue cancer therapies for cancer control and cure is critical.

Comprehensive genomic sequencing of paired ovarian cancers reveals discordance in genes that determine clinical trial eligibility.

OBJECTIVE: We analyzed comprehensive genomic sequencing results from paired ovarian cancer samples to identify changes in mutational events over time. METHODS: DNA from paired FFPE tumor samples from 50 ovarian cancer patients in the Clearity Foundation Data Repository was analyzed for genomic mutations (GM), copy number alterations (CNA), microsatellite status (MS), tumor mutation burden (TMB), and loss of heterozygosity (LOH) by hybrid-capture, next-generation sequencing of up to 315 genes. Genomic profiles were compared between samples from the same patient. Poor quality results excluded 6 pairs from all analyses and 9 from CNA or LOH. RESULTS: Forty-four patients with predominantly advanced stage disease (34, 77%) and serous histology (31, 70%) received a median of 3 intervening treatment regimens (range 1-13). Analysis of 22 primary and recurrent sample pairs and 22 recurrent tumor pairs detected a median of 2 GM (range 0-5) and 1 CNA (range 0-6)/sample. TMB, MS, and LOH results were mostly concordant across paired samples. GM were consistent across most pairs [32/44 (73%) concordant], while CNA concordance was less [18/35 (51%)]. No changes were detected in therapeutically relevant GM, but 23% of patients had GM or CNA in the second sample that affect clinical trial eligibility. CONCLUSIONS: Paired ovarian cancer samples demonstrate stable genomic alterations across time. However, discordance was observed for some genes used as eligibility criteria for molecularly targeted clinical trials. Repeat tumor testing may be useful in cases where eligibility for such trials is deemed important after consideration of testing costs and potential clinical benefit.

Small cell cancers of the female genital tract: Molecular and clinical aspects.

OBJECTIVE: Extra-pulmonary small cell carcinomas of the gynecologic tract (EPSCC-GTs) are a rare group of aggressive malignancies associated with poor prognoses and limited treatment options. Here, we review the clinical and molecular aspects of EPSCC-GTs and discuss how understanding their molecular features can assist in their diagnosis and the identification of novel effective treatments. METHODS: We searched PubMed and Scopus for articles using the following keywords: "small cell carcinoma" in combination with "neuroendocrine", "ovary", "vagina", "fallopian tube", "vulva", "endometrium", "uterus", "cervix", or "gynecologic". Articles were limited to those published in English from January 1984 to October 2017. RESULTS: EPSCC-GTs account for 2% of all gynecologic malignancies. The molecular features of EPSCC-GTs are largely understudied and unknown, with the exception of small cell carcinoma (SCC) of the ovary, hypercalcemic type (SCCOHT) and SCC of the cervix (SCCC). In nearly all cases, SCCOHT displays mutation in a single gene, SMARCA4, a member of the SWI/SNF chromatin remodeling complex. The loss of expression of the SWI/SNF protein SMARCA2 is another feature of SCCOHT. Dual negative staining for SMARCA2 and SMARCA4 is specific for SCCOHT and is generally used by gynecologic pathologists for the accurate diagnosis of this malignancy. Mutational analysis of SCCC has shown alterations in PIK3CA, KRAS and TP53, of which the last is the most common, although other actionable mutations have been identified. The molecular features of other EPSCC-GTs are largely unknown. CONCLUSIONS: Due to their rarity, the majority of EPSCC-GTs are understudied and poorly understood. As demonstrated in the case of SCCOHT, unraveling the mutational profiles of these tumors can lead to improved diagnosis and the identification of novel therapeutic targets.

Missed opportunities: Genetic counseling and testing among an ethnically diverse cohort of women with endometrial cancer.

OBJECTIVES: Lynch syndrome (LS) accounts for the majority of inherited endometrial cancers (EC), and the identification of probands presents a unique opportunity to treat and prevent multiple cancers. The diagnosis of EC can provide the indication for women with specific risk factors to undergo genetic testing (GT). We sought to evaluate genetic counseling referrals (GCR) and subsequent GT rates in an ethnically diverse group of high-risk women. METHODS: All women diagnosed with EC between 2011 and 2016 were identified. Risk factors for LS including age, family and personal histories of Lynch-related cancers and loss of tumor mismatch repair (MMR) protein expression were identified from laboratory and medical records. Standard two-sided statistical tests were used. RESULTS: Of 583 women diagnosed with EC, 184 (31.6%) were found to have at least one high-risk characteristic for LS. Among these high-risk women, 58% were given GCR and resulting in only 35% undergoing GT. Ten of the 65 high-risk women who had GT (15.4%) were diagnosed with Lynch syndrome, and all ten met high-risk criteria. Two women of Asian race had tumors exhibiting retained MMR protein expression despite germline testing demonstrating Lynch syndrome. CONCLUSIONS: Many high-risk women do not receive GCR despite a high rate of germline mutations among these women. Improving GCR among high-risk women will lead to more subsequent GT to identify more Lynch syndrome families and prevent additional cancers. Among our ethnically diverse cohort, two women diagnosed with LS had retained MMR protein expression. GCR should be offered to women who possess high-risk characteristics despite normal MMR protein expression.

Risk-reducing salpingo-oophorectomy and ovarian cancer screening in 1077 women after BRCA testing.

BACKGROUND: For women at potentially increased risk for ovarian cancer, data regarding screening and risk reduction are limited. Previous studies have reported on the behaviors of BRCA mutation carriers, but less is known about the behaviors of non- BRCA carriers. We surveyed a large cohort of women after BRCA testing to identify the prevalence and posttest predictors of risk-reducing and screening interventions. METHODS: A median of 3.7 years after BRCA testing, 1447 women who received genetic counseling and BRCA testing at 2 hospital sites were surveyed, with a 77.6% response rate. We analyzed data from 1077 survey respondents. We performed univariate and multivariate logistic regression analyses to identify predictors of risk-reducing salpingo-oophorectomy (RRSO), screening transvaginal ultrasonography (TVUS), and screening serum cancer antigen 125 (CA-125). RESULTS: Among the respondents, 201 women (18.7%) received positive test results for a deleterious mutation, 103 women (9.6%) received true-negative results, and 773 women (71.8%) received uninformative results. Overall, 19.1% of eligible women underwent RRSO and 39.6% used screening procedures. A positive BRCA result predicted RRSO (odds ratio [OR], 28.1; 95% CI, 16.2-48.6), TVUS (9.5 [4.3-21.0]), and serum CA-125 (13.0 [5.5-29.0]). Similarly, a true-negative BRCA result reduced the OR for RRSO (0.1 [0.0-0.6]), TVUS (0.2 [0.1-0.5]), and serum CA-125 (0.3 [0.1-0.7]). Of the 71.8% of women who received uninformative results after BRCA testing, 12.3% subsequently underwent RRSO, 33.8% reported ever having undergone screening serum CA-125 since BRCA testing, and 37.3% reported ever having undergone screening TVUS since BRCA testing. CONCLUSIONS: Results of BRCA testing strongly predict RRSO and ovarian cancer screening. Use of RRSO and ovarian screening was reported in a sizable percentage of non- BRCA carriers despite insufficient data to determine the effectiveness of these interventions.

Childbirth and female sexual function later in life.

OBJECTIVE: To examine relationships among parity, mode of delivery, and other parturition-related factors with women's sexual function later in life. METHODS: Self-administered questionnaires examined sexual desire, activity, satisfaction, and problems in a multiethnic cohort of women aged 40 years and older with at least one past childbirth event. Trained abstractors obtained information on parity, mode of delivery, and other parturition-related factors from archived records. Multivariable regression models examined associations with sexual function controlling for age, race or ethnicity, partner status, diabetes, and general health. RESULTS: Among 1,094 participants, mean (standard deviation) age was 56.3 (±8.7) years, 568 (43%) were racial or ethnic minorities (214 African American, 171 Asian, and 183 Latina), and 963 (88%) were multiparous. Fifty-six percent (n=601) reported low sexual desire; 53% (n=577) reported less than monthly sexual activity, and 43% (n=399) reported low overall sexual satisfaction. Greater parity was not associated with increased risk of reporting low sexual desire (adjusted odds ratio [OR] 1.08, confidence interval [CI] 0.96-1.21 per each birth), less than monthly sexual activity (adjusted OR 1.05, CI 0.93-1.20 per each birth), or low sexual satisfaction (adjusted OR 0.96, CI 0.85-1.09 per each birth). Compared with vaginal delivery alone, women with a history of cesarean delivery were not significantly more likely to report low desire (adjusted OR 0.71, CI 0.34-1.47), less than monthly sexual activity (adjusted OR 1.03, CI 0.46-2.32), or low sexual satisfaction (adjusted OR 0.57, CI 0.26-1.22). Women with a history of operative-assisted delivery were more likely to report low desire (adjusted OR 1.38, CI 1.04-1.83). CONCLUSIONS: Among women with at least one childbirth event, parity and mode of delivery are not major determinants of sexual desire, activity, or satisfaction later in life. LEVEL OF EVIDENCE: II.
