Parity, menopausal hormone therapy, and risk of ovarian granulosa cell tumor - A population-based case-control study.

Objective: Adult-type ovarian granulosa cell tumors (AGCTs) are hormonally active neoplasms with limited epidemiological data available. We evaluated the effect of parity and postmenopausal hormone therapy (HT) use on the risk of AGCT in a population-based case-control setting.

Methods: We identified all women diagnosed with AGCT during 1994-2015 (n = 505) from the Finnish Cancer Registry.

Other Primary Malignancies Among Women With Adult-Type Ovarian Granulosa Cell Tumors.

Objective: The aim of this study was to determine the incidence of new primary malignancies after adult-type granulosa cell tumor (AGCT) and the incidence of AGCT after breast and uterine cancer using nationwide population-based registry data.

Methods: We used the Finnish Cancer Registry to identify all patients diagnosed with AGCT in 1968 to 2013 (n = 986). The number of subsequent primary malignancies among women with AGCT and the number of AGCTs in women with previous breast or uterine cancer were compared with the expected number of cases and expressed as standardized incidence ratios (SIRs).

Characteristics and outcome of recurrence in molecularly defined adult-type ovarian granulosa cell tumors.

Objective: Adult-type ovarian granulosa cell tumors (AGCTs) have an unpredictable tendency to relapse. In a carefully validated patient cohort, we evaluated the prognostic factors related to AGCT recurrence.

Methods: We identified all patients diagnosed with AGCT during 1956-2014 in Helsinki University Hospital, with a minimum follow-up of one year (n=240).

Molecularly Defined Adult Granulosa Cell Tumor of the Ovary: The Clinical Phenotype.

The histopathologic features of adult granulosa cell tumors (AGCTs) are relatively nonspecific, resulting in misdiagnosis of other cancers as AGCT, a problem that has not been well characterized. FOXL2 mutation testing was used to stratify 336 AGCTs from three European centers into three categories: 1) FOXL2 mutant molecularly defined AGCT (MD-AGCT) (n = 256 of 336), 2) FOXL2 wild-type AGCT (n = 17 of 336), 3) misdiagnosed other tumor types (n = 63 of 336). All statistical tests were two-sided.

The clinical utility of serum anti-Müllerian hormone in the follow-up of ovarian adult-type granulosa cell tumors--A comparative study with inhibin B.

Ovarian adult-type granulosa cell tumors (AGCTs) require prolonged follow-up, but evidence regarding the optimal follow-up marker is lacking. The objective of our study was to validate the clinical usefulness of serum anti-Müllerian hormone (AMH) and the current marker inhibin B as single and combined markers of AGCTs. We conducted a longitudinal, partially prospective cohort study of 123 premenopausal and postmenopausal AGCT patients with a median follow-up time of 10.

Clinical characteristics and survival of patients with an adult-type ovarian granulosa cell tumor: a 56-year single-center experience.

Objective: The objective of this study was to evaluate clinical prognostic factors and survival of patients with ovarian granulosa cell tumors (GCTs) in a long-term follow-up study.

Methods: A total of 240 adult-type GCTs diagnosed in Helsinki University Central Hospital from 1956 to 2012 were histologically reevaluated. Data were analyzed for several clinical factors in relation to major developments in imaging, surgery, and chemotherapy: the old era (1956-1983) and the new era (1984-2012).
