Posterior-scleritis: Case report of an uncommon immune-related adverse event in the treatment of advanced endometrial cancer

As Immune checkpoint inhibitors are being expanded for use in gynecologic malignancies, rare immune-related adverse events are more frequently being reported. Here we describe a 63-year-old with Stage IIIB mismatch repair deficient uterine adenocarcinoma who underwent six cycles of carboplatin and paclitaxel with partial response but persistent disease. She was then started on single agent pembrolizumab. After six cycles of pembrolizumab, she developed bilateral vision changes and was diagnosed with posterior scleritis. Pembrolizumab was held and she was treated with oral prednisone, with rapid resolution of symptoms. One month after completion of prednisone, vision changes were again reported and she was restarted on a longer oral prednisone course. She then underwent definitive surgical management consisting of a total laparoscopic hysterectomy and bilateral salpingo-oophorectomy, with final pathology of benign endometrial hyperplasia. She has completed her steroid course without any symptoms. Given her complete pathologic response, she was subsequently placed into surveillance and is currently without evidence of disease. Prompt recognition and treatment of this rare immune-related adverse event led to the prevention of potential permanent, debilitating outcomes.

Opportunities Missed: Cervix Cancer Screening Failures in Women Aged 65 and Older

OBJECTIVES

This study aimed to determine the screening history and associated outcomes of women diagnosed with cervical cancer after age 65.

METHODS

All patients from 2012 to 2021 diagnosed with squamous, adenocarcinoma, neuroendocrine, or adenosquamous cervical cancer after age 65 in a single managed care organization (MCO) were included in this retrospective cohort study. Demographic, medical, screening, pathologic, follow-up, and treatment data were extracted. Statistical analysis was done using chi-square test and logistic regression. Cancer-specific survival was estimated using the Kaplan-Meier method.

RESULTS

Of 2,175 patients screened, 209 met inclusion criteria. Only 26.3% of patients had appropriate cervical cancer screening and 41% of patients died of their disease. Managed care organization membership duration of more than 5 years positively correlated with proper cervical cancer screening ( p < .001); however, 64% of the long-term members still did not meet criteria to end screening at age 65, with 42.6% of these patients having more than 25 physician visit opportunities to address screening. Increased physician visits correlated with earlier stage at diagnosis of cervical cancer ( p = .012). Median cancer-specific survival was significantly better in properly screened patients at 68 vs 30 months, respectively ( p = .03).

CONCLUSIONS

Most patients diagnosed with cervical cancer after age 65 did not have adequate previous screening, including those who were MCO members for more than 5 years. There were many missed opportunities for screening, despite multiple provider touchpoints. The authors' data suggest that adequate screening confers a survival benefit secondary to earlier stage at diagnosis. Further study in this age group is needed to redefine the criteria to end cervix cancer screening.

Juvenile granulosa cell tumor in a transgender male with Ollier disease: A case report

•Multiple case reports are published on patients with Ollier's disease presenting simultaneously with granulosa cell tumors.•More medical conditions are being treated with androgens and estrogens, including gender dysphoria.•Caution should be given to transgender patients on active hormonal therapy.•Providers should consider prescreening for hormonally responsive medical conditions.

Racial Disparities in Brachytherapy Treatment among Women with Cervical and Endometrial Cancer in the United States

Brachytherapy improves clinical outcomes among women diagnosed with cervical and endometrial cancers. Recent evidence demonstrates that declining brachytherapy boosts for women with cervical cancer were associated with higher mortality. In this retrospective cohort study, women diagnosed with endometrial or cervical cancer in the United States between 2004 and 2017 were selected from the National Cancer Database for evaluation. Women ≥18 years of age were included for high intermediate risk (PORTEC-2 and GOG-99 definition) or FIGO Stage II-IVA endometrial cancers and FIGO Stage IA-IVA-non-surgically treated cervical cancers. The aims were to (1) evaluate brachytherapy treatment practice patterns for cervical and endometrial cancers in the United States; (2) calculate rates of brachytherapy treatment by race; and (3) determine factors associated with not receiving brachytherapy. Treatment practice patterns were evaluated over time and by race. Multivariable logistic regression assessed predictors of brachytherapy. The data show increasing rates of brachytherapy for endometrial cancers. Compared to non-Hispanic White women; Native Hawaiian and other Pacific Islander (NHPI) women with endometrial cancer and Black women with cervical cancer were significantly less likely to receive brachytherapy. For both NHPI and Black women, treatment at community cancer centers was associated with a decreased likelihood of brachytherapy. The data suggest racial disparities among Black women with cervical cancer and NHPI women with endometrial cancer and emphasize an unmet need for brachytherapy access within community hospitals.

The kelch protein KLHDC8B guards against mitotic errors, centrosomal amplification, and chromosomal instability

The malignant cell in classical Hodgkin lymphoma (HL) is the binucleated giant Reed-Sternberg cell. Chromosomal instability and mitotic errors may contribute to HL pathogenesis; one potential mitotic regulator is the kelch protein KLHDC8B, which localizes to the midbody, is expressed during mitosis, and is mutated in a subset of familial and sporadic HL. We report that disrupting KLHDC8B function in HeLa cells, B lymphoblasts, and fibroblasts leads to significant increases in multinucleation, multipolar mitoses, failed abscission, asymmetric segregation of daughter nuclei, formation of anucleated daughter cells, centrosomal amplification, and aneuploidy. We recapitulated the major pathologic features of the Reed-Sternberg cell and concluded that KLHDC8B is essential for mitotic integrity and maintenance of chromosomal stability. The significant impact of KLHDC8B implicates the central roles of mitotic regulation and chromosomal segregation in the pathogenesis of HL and provides a novel molecular mechanism for chromosomal instability in HL.
