SGO and the elephant that is still in the room: Wellness, burnout and gynecologic oncology

OBJECTIVE

To measure wellness and burnout among gynecologic oncology clinicians and identify trends and at-risk populations to inform future interventions.

METHODS

Gynecologic oncologist (GO) and advanced practice provider (APP) responses to the 2020 Society of Gynecologic Oncology State of the Society survey were analyzed. The Maslach Burnout Inventory criteria for burnout was used. Work-life balance was scored on a 5-point Likert scale. Chi-square tests were used to compare mental health factors and the prevalence of burnout. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for associations between burnout and gender.

RESULTS

543 survey responses were included for analysis. Most GO (54%) and all APP respondents were female. Female GOs were disproportionately affected by burnout particularly in the Northeast (female(F): 40.9% vs male(M): 19.1%, p = 0.007) and South (F: 42.5% vs M:22.9%, p = 0.01). Burnout in female GOs over 40 was 1.79 (CI: 1.13-2.83; p-value 0.01) times higher than similarly aged males. Females in non-private practice experienced burnout 1.66 times that of males in similar positions (CI: 1.18-2.94; p < 0.0001). Female GOs reported the worst work-life balance across all 5 domains. APPs and female GOs experienced more stress and feeling overwhelmed compared to men. GOs were more reluctant to see a mental health professional (p = 0.0003) or take medication (p = 0.009) than APPs.

CONCLUSIONS

Burnout in gynecologic oncology persists in both genders and is felt most acutely by female GOs. APPs are not immune and would benefit from inclusion in future research to mitigate burnout in healthcare clinicians.

Allelotype of papillary serous peritoneal carcinomas

OBJECTIVE

Papillary serous peritoneal carcinoma (PSPC) is histologically indistinguishable from papillary serous ovarian carcinoma (PSOC) with a similar clinical presentation, yet may differ in its carcinogenesis. The purpose of this study was to determine the incidence of allelic loss and the frequency of p53 mutation by p53 overexpression in PSPC compared to PSOC.

METHODS

An allelotype analysis of 26 patients with PSPC was performed using 39 microsatellite markers from 25 chromosomal arms. Thirty-seven previously studied patients with PSOC served as the comparison. P53 mutations were detected by immunohistochemical protein overexpression.

RESULTS

There was significantly less LOH in PSPC than PSOC. Both the number of chromosomes with LOH and the proportion of tumors with allelic loss were less frequent. Significant LOH, defined as >/=30% of informative tumors having loss at a chromosome locus, was seen on 4 chromosome arms in PSPC: 12p, 17p, 17q, and 18q, compared to 18 arms in PSOC: 4q, 5q, 6p, 6q, 9p, 9q, 12p, 12q, 13q, 15q, 16q, 17p, 17q, 18q, 19p, 19q, 22q, and Xq (P < 0.001). The median LOH frequency was higher in PSOC than PSPC, 43% versus 33%, respectively (P = 0.013), and more PSOC tumors had LOH than PSPC tumors, 91% versus 65% (P = 0.042). P53 overexpression was detected in 80% of PSPC tumors.

CONCLUSIONS

LOH occurs less frequently in PSPC compared to PSOC. Chromosomal regions with high frequencies of LOH common to PSPC and PSOC, such as 12p, 17p, 17q, and 18q, may harbor tumor suppressor genes important in the carcinogenesis of both malignancies and likely include p53.

Pattern of lymph node metastases in clinically unilateral stage I invasive epithelial ovarian carcinomas

PURPOSE

There is controversy regarding the pattern of lymphatic spread in unilateral stage I invasive ovarian carcinomas. The purpose of this study is to describe the incidence and distribution of lymph node (LN) metastases in ovarian carcinomas clinically confined to one ovary.

METHODS

Ninety-six patients with disease visibly confined to one ovary were identified. Pathology reports were reviewed to identify metastatic LN involvement, number of involved nodes, and their locations. Patients with gross disease in the pelvis or abdomen or those who had grossly positive LNs removed for debulking were excluded from this review.

RESULTS

Fourteen of ninety-six patients (15%) had microscopically positive LNs on pathologic review. All of these 14 patients had grade 3 tumors. Grade 3 tumors were more commonly seen in LN-positive versus LN-negative patients (P < 0.001). Pelvic nodes were positive in 7 patients (50%), paraaortic nodes in 5 patients (36%), and both in 2 patients (14%). Forty-two patients had LN sampling only on the side ipsilateral to the neoplastic ovary, 4 of whom (10%) had LN metastases. Fifty-four patients had bilateral sampling performed, 10 of whom (19%) had LN metastases. Of these 10 patients, isolated ipsilateral LN metastases were seen in 5 (50%) cases. Isolated contralateral LN metastases were seen in 3 (30%) cases, and bilateral metastases were seen in 2 (20%).

CONCLUSIONS

In this cohort of patients with clinical stage I ovarian carcinoma with disease limited to one ovary, bilateral LN sampling increased the identification of nodal metastases. Ipsilateral sampling may result in the understaging of patients. Bilateral pelvic and paraaortic LN sampling is recommended to accurately stage ovarian carcinoma.

BRCA1 promoter region hypermethylation in ovarian carcinoma: a population-based study

There is a clear association between germ-line BRCA1 mutations and inherited ovarian cancer; however, the association between BRCA1 mutations and sporadic ovarian cancer remains ambiguous. The frequency of BRCA1 promoter hypermethylation as an epigenetic means of BRCA1 inactivation was determined for a large, population-based cohort of ovarian cancer patients. BRCA1 promoter hypermethylation was determined by methylation-specific restriction digestion of tumor DNA, followed by Southern blot analysis and confirmed by methylation-specific PCR. BRCA1 promoter hypermethylation was observed in 12 of 98 ovarian tumors. BRCA1 methylation status of the primary tumor was conserved in six recurrent tumors after interim chemotherapy. None of the 12 tumors with BRCA1 promoter hypermethylation demonstrated BRCA1 protein expression by immunohistochemistry. BRCA1 methylation was only seen in ovarian cancer patients without a family history suggestive of a breast/ ovarian cancer syndrome. Therefore, the 12 BRCA1 methylated tumors represented 15% (12 of 81) of the sporadic cancers analyzed in this study. Although the clinical significance of BRCA1 promoter hypermethylation is yet to be determined, promoter hypermethylation may be an alternative to mutation in causing the inactivation of the BRCA1 tumor suppressor gene in sporadic ovarian cancer.

Molecular advances in gynecologic oncology

Cancer is a genetic disease, and inherited or acquired genetic defects contribute to the initiation and progression of cancer. Improved molecular techniques have lead to the identification of many of these genetic mutations in gynecologic malignancies. The molecular characterization of cancer has provided a better understanding of tumor formation and the clinical behavior of different tumor types, with important implications for developing screening tests and prognostic markers. Applications of these findings have led to novel targeted gene therapies that correct the critical genetic defects seen in gynecologic cancers. Future research will focus on the clinical translation of these genetic alterations as targets of cancer prevention, screening, and treatment.

Malignant Brenner tumor mimicking a primary squamous cell carcinoma of the cervix

An 86-year-old female presented with a necrotic cervical mass that was biopsy-proven squamous cell carcinoma. She had an elevated CA-125 and a pelvic mass. At surgery, this mass was found to be of adnexal origin and contiguous with the cervix. Histology showed a malignant Brenner tumor with abundant squamous differentiation eroding the cervix and simulating a primary cervical malignancy. We describe this case and review the literature on metastatic tumors to the cervix.

A case of fatal pulmonary thromboembolism associated with the use of intravenous estrogen therapy

OBJECTIVE

To report a case of fatal pulmonary embolism associated with the use of i.v. estrogen therapy for menometrorrhagia.

DESIGN

Case report.

SETTING

University hospital.

PATIENT(S)

A 52-year-old woman with fibroid uterus treated with GnRH analogues with add-back therapy who presented with excessive vaginal bleeding.

INTERVENTION(S)

Intravenous conjugated estrogens were administered for a total of six doses.

MAIN OUTCOME MEASURE(S)

Fatal thromboembolic event.

RESULT(S)

The day after i.v. conjugated estrogens were administered, the patient had only scant vaginal bleeding, but she experienced the sudden onset of respiratory distress, became comatose, and subsequently had ventricular fibrillation leading to asystole. All resuscitative efforts failed. Postmortem examination revealed bilateral pulmonary artery thromboembolism (saddle embolus).

CONCLUSION(S)

Intravenous conjugated estrogen therapy may be complicated by fatal thromboembolic events. This potential adverse effect must be considered in the use of such therapy for severe menometrorrhagia, especially when treating a patient at increased risk.
