Abstract

Objectives: To evaluate survival outcomes among patients with adult-type granulosa cell tumors who have telomerase reverse transcriptase (TERT) promoter mutations.

Methods: 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.

Results: 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).

Conclusions: 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.
