TERT promoter mutations and survival outcomes in adult-type granulosa cell tumors

To evaluate survival outcomes among patients with adult-type granulosa cell tumors who have telomerase reverse transcriptase (TERT) promoter mutations. This is a retrospective cohort study using the MD Anderson Rare Gynecologic Malignancy Registry. Patients with adult granulosa cell tumors who underwent molecular testing for TERT promoter and FOXL2 c.C402G mutations were included. We used descriptive statistics to compare demographic and clinical variables and estimated progression-free and overall survival with Kaplan-Meier curves. Cox proportional hazards regression and log-rank tests were employed for comparisons, with multivariable analyses adjusting for various factors. Among 70 patients, 28 (40%) had TERT+ tumors. The median age at diagnosis was 40 years (range 12-71) for TERT- patients and 46 years (range 25-76) for TERT+ patients. At diagnosis, 22 (63%) of 35 TERT- patients were stage I, 10 (29%) stage II, and 3 (9%) stage III, while in the TERT+ group, 17/23 (74%) were stage I, 3 (13%) stage II, and 3 (13%) stage II. Univariable analysis showed no difference in time from diagnosis to first recurrence (p=0.19) and from first recurrence to second recurrence (p=0.24) based on tumor TERT status. The median time from first to second recurrence in the TERT- group was 27.3 months (95% CI 14.1 to 40.0) and in the TERT+ group was 14.8 months (95% CI 8.1 to 21.0). There was no observed difference in overall survival between the groups (HR=0.53; 95% CI 0.19 to 1.45; p=0.21).Multivariable analysis adjusting for age at diagnosis, TERT promoter mutation status, systemic chemotherapy, and stage demonstrated a significant difference in progression-free survival based on TERT mutation status (HR=2.89; 95% CI 1.32 to 6.36). After adjustment for covariates, patients with adult granulosa cell tumors and TERT+ tumors had shorter progression-free survival after first recurrence. TERT promoter mutations may identify a subset of patients with recurrent adult granulosa cell tumors and less favorable outcomes.

Surgical and Blood-Based Minimal Residual Disease in Patients with Ovarian Cancer after First-line Therapy: Clinical Outcomes and Translational Opportunities

Abstract Purpose: Minimal residual disease (MRD) after first-line treatment of advanced-stage ovarian cancer remains a long-standing barrier to cure. We investigated the prognostic and translational value of MRD detection by second-look laparoscopy (SLL) and ctDNA at the completion of first-line therapy. Experimental Design: Patients with high-grade epithelial ovarian cancer who had a complete clinical response to first-line therapy and underwent SLL and plasma collection for ctDNA were included. Progression-free survival (PFS) and overall survival (OS) were estimated based on MRD and clinicopathologic status. Spatial transcriptomics (GeoMx and Visium) and proteomics (CODEX) profiling were performed on serial samples from select patients. Results: Forty of 95 (42.1%) patients had surgically detected MRD, which was associated with worse PFS (median PFS 7.4 vs. 23.8 months; P < 0.001) and OS (median OS 33.9 vs. not reached; P < 0.001). SLL positivity was an independent negative prognostic factor for OS (HR, 4.40; 95% confidence interval, 1.37–14.21; P = 0.013) in multivariable analysis. Among 44 patients who underwent SLL and had ctDNA testing, 34% (15/44) were ctDNA-positive, which was associated with worse PFS (6.4 vs. 28.1 months; P < 0.001) and OS (32.4 months vs. not reached; P = 0.008). We demonstrated the feasibility of spatial multiomics in studying MRD and their ability to provide hypothesis-generating observations, implicating the upregulation of the hypoxia signaling pathway, expression of multiple druggable targets (CDK6, GLS, MSLN, ERBB2), and immune exclusion in MRD lesions. Conclusions: Approximately half of patients in clinical remission after first-line therapy have assessable MRD, which can inform prognosis, therapeutic target discovery, and clinical trials.

Knowledge matters and empowers: HPV vaccine advocacy among HPV-related cancer survivors

To describe knowledge about human papillomavirus (HPV), HPV-related care behavior, and advocacy intent (e.g., vaccine recommendation and willingness to become an advocate for vaccination) and to investigate associations between knowledge, HPV-related care behavior, and advocacy intent among HPV-related cancer survivors. A cross-sectional online survey was offered through Qualtrics to HPV-related cancer survivors who were either volunteers at a cancer center or patients of survivorship clinics. A total of 200 survivors responded. Only 33.2% of respondents reported knowing their cancer was HPV-related and 56.8% reported HPV vaccine is safe. Participants who knew that their cancer was caused by HPV were more likely to have vaccinated their children (p < .001). Also, participants who knew that the vaccine is safe were more willing to recommend the vaccine (p < .001), to be a peer mentor for others with HPV-related cancers (43.2% vs. 14.0%, p < .001), and to act as an advocate for increasing vaccination rates (44.1% vs. 24.4%, p = 0.01). Finally, survivors who were aware of the vaccine's effectiveness in decreasing precancerous lesions were more likely to recommend the vaccine (45.7% vs. 12.0%, p = .002). Raising survivor awareness of the link between HPV and cancer and HPV vaccine safety may increase their willingness to serve as powerful opinion leaders and peer mentors to promote HPV vaccination. Providers may take the simple step of informing patients that their cancer is HPV-related and HPV vaccine is safe to increase the number of informed and empowered survivors.

Vulvar Cancer Incidence in the United States and its Relationship to Human Papillomavirus Vaccinations, 2001–2018

Abstract The human papillomavirus (HPV) vaccine was indicated for the prevention of vulvovaginal cancers in 2008, but its impact on the incidence of vulvar cancers within the US is unknown. To determine this, we conducted a secondary analysis of 88,942 vulvar cancer cases among women 20+ years old using the US Cancer Statistics 2001–2018 databases. Data were stratified by tumor behavior (in situ or invasive), age (20–44, 45–64, 65+ years old), race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic), and US census region (Northeast, South, Midwest, West), and incidence rates and average annual percentage changes (AAPC) were calculated by group. Reversing previous trends, the incidence of vulvar carcinoma in situ significantly decreased between 2001 and 2018 among women from all age groups, races/ethnicities, and regions (combined AAPC,  −4.3; 95% confidence interval (CI), −4.7 to −3.8). The incidence of invasive vulvar squamous cell carcinoma decreased significantly among 20- to 44-year-old women (AAPC, −0.8; 95% CI, −1.3 to −0.3), but significantly increased among those 45 to 64 (AAPC, 2.3; 95% CI, 1.8–2.8) and 65+ years old (AAPC, 1.2; 95% CI, 1.1–1.4). Regardless of tumor behavior, incidence was highest among non-Hispanic Whites and the Midwest region. Overall, the significant declines in vulvar carcinoma in situ among all ages, as well as invasive vulvar cancer among younger women, are encouraging and complement other recent data suggesting HPV vaccinations are already reducing anal and cervical cancer incidence. Over time, further declines in vulvar carcinoma incidence are likely as uptake and completion rates of the HPV vaccine increase in the US. Prevention Relevance: We found evidence that HPV vaccinations likely contributed to a decrease in the incidences of vulvar carcinoma in situ and invasive vulvar carcinoma among 20- to 44-year-old women between 2001 and 2018. Our data add to the growing evidence that HPV vaccinations are reducing the incidence of HPV-related anogenital cancers.
