Ovarian Sertoli-Leydig cell tumours: A systematic review of relapsed cases

Outcomes in ovarian Sertoli-Leydig cell tumor: A report from the International Pleuropulmonary Blastoma/DICER1 and Ovarian and Testicular Stromal Tumor Registries

OBJECTIVE

Sertoli-Leydig cell tumors (SLCTs) are rare sex cord-stromal tumors, representing <0.5% of all ovarian tumors. We sought to describe prognostic factors, treatment and outcomes for individuals with ovarian SLCT.

METHODS

Individuals with SLCT were enrolled in the International Pleuropulmonary Blastoma/DICER1 Registry and/or the International Ovarian and Testicular Stromal Tumor Registry. Medical records were systematically abstracted, and pathology was centrally reviewed when available.

RESULTS

In total, 191 participants with ovarian SLCT enrolled, with most (92%, 175/191) presenting with FIGO stage I disease. Germline DICER1 results were available for 156 patients; of these 58% had a pathogenic or likely pathogenic germline variant. Somatic (tumor) DICER1 testing showed RNase IIIb hotspot variants in 97% (88/91) of intermediately and poorly differentiated tumors. Adjuvant chemotherapy was administered in 40% (77/191) of cases, and among these, nearly all patients received platinum-based regimens (95%, 73/77), and 30% (23/77) received regimens that included an alkylating agent. Three-year recurrence-free survival for patients with stage IA tumors was 93.6% (95% CI: 88.2-99.3%) compared to 67.1% (95% CI: 55.2-81.6%) for all stage IC and 60.6% (95% CI: 40.3-91.0%) for stage II-IV (p < .001) tumors. Among patients with FIGO stage I tumors, those with mesenchymal heterologous elements treated with surgery alone were at higher risk for recurrence (HR: 74.18, 95% CI: 17.99-305.85).

CONCLUSION

Most individuals with SLCT fare well, though specific risk factors such as mesenchymal heterologous elements are associated with poor prognosis. We also highlight the role of DICER1 surveillance in early detection of SLCT, facilitating stage IA resection.

Sertoli-Leydig cell tumor with DICER1 mutation

Sertoli-Leydig cell tumors (SLCT) are a rare form of sex cord stromal tumors. DICER1 germline mutations have been identified in a portion of these cases. We report a 15-year-old individual who presented to a well-child visit with secondary amenorrhea and subjective observations of a deepening voice and broadening shoulders. Elevations were noted in serum testosterone, inhibin B, androstenedione, and DHEA. Pelvic ultrasound and magnetic resonance imaging (MRI) revealed a left ovarian complex lesion measuring 5.8 x 5.5 x 4.6 cm. A laparoscopic unilateral salpingo-oophorectomy was performed with negative pelvic washings and a diagnosis of stage 1A, poorly differentiated/grade 3 SLCT of the ovary. Somatic and germline testing both demonstrated DICER1 pathologic variations. Adjuvant chemotherapy with cisplatin/etoposide/ifosfamide (PEI) was completed under the care of pediatric oncology, and this patient is now undergoing surveillance with no signs of recurrence. DICER1 Syndrome is associated with multiple tumors, including SLCT, pleuropulmonary blastoma (PPB), cystic sarcomas, and Wilms tumor among others. Patients with SLCT found to have a DICER1 mutation should undergo genetic testing and cancer screening, which may help to identify neoplasms associated with the DICER1 mutation at an early stage. This case will serve as a useful addition to the literature and review suggested pre-operative, operative, and surveillance guidelines.

Imaging in gynecological disease (27): clinical and ultrasound characteristics of recurrent ovarian stromal cell tumors

OBJECTIVE

To describe the clinical and ultrasound characteristics of recurrent granulosa cell and Sertoli-Leydig cell tumors.

METHODS

This was a retrospective observational study performed at Fondazione Policlinico Universitario A. Gemelli, Istituto di Ricovero e Cura a Carattere Scientifico, IRCCS, Rome (Gemelli center), Italy. Patients with a histological diagnosis of recurrent granulosa cell tumor or Sertoli-Leydig cell tumor were identified from the database of the Department of Gynecological Oncology. Those who had undergone a preoperative ultrasound examination at the Gemelli center between 2012 and 2020 were included, and the data retrieved from the original ultrasound reports. In all of these reports, the recurrent tumors were described using International Ovarian Tumor Analysis (IOTA) terminology. If a patient had more than one episode of relapse, information from all episodes was collected. If there was more than one recurrent tumor at the same ultrasound examination, all tumors were included. One expert sonographer also reviewed all available ultrasound images to identify typical ultrasound patterns using pattern recognition.

RESULTS

We identified 30 patients with a histological diagnosis of recurrent granulosa cell tumor (25 patients, 55 tumors) or Sertoli-Leydig cell tumor (five patients, seven tumors). All 30 had undergone at least one preoperative ultrasound examination at the Gemelli center and were included. These women had a total of 66 episodes of relapse, of which a preoperative ultrasound examination had been performed at the Gemelli center in 34, revealing 62 recurrent lesions: one in 22/34 (64.7%) episodes of relapse, two in 4/34 (11.8%) episodes and three or more in 8/34 (23.5%) episodes. Most recurrent granulosa cell tumors (38/55, 69.1%) and recurrent Sertoli-Leydig tumors (6/7, 85.7%) were classified as solid or multilocular-solid tumors, while 8/55 (14.5%) recurrent granulosa cell tumors and 1/7 (14.3%) recurrent Sertoli-Leydig cell tumors were unilocular cysts and 9/55 (16.4%) recurrent granulosa cell tumors were multilocular cysts. The nine unilocular cysts had contents that were anechoic (n = 2) or had low-level echogenicity (n = 7), had either smooth (n = 4) or irregular (n = 5) internal cyst walls, and ranged in largest diameter from 8 to 38 mm, with three being < 20 mm and five being 20-30 mm. On retrospective review of the images, two typical ultrasound patterns were described: small solid tumor measuring < 2 cm (15/62, 24.2%) and tumor with vascularized echogenic ground-glass-like content (12/62, 19.4%).

CONCLUSIONS

Some granulosa cell and Sertoli-Leydig cell recurrences manifest one of two typical ultrasound patterns, while some appear as unilocular cysts. These are usually classified as benign, but in patients being followed up for a granulosa cell tumor or Sertoli-Leydig cell tumor, a unilocular cyst should be considered suspicious of recurrence. © 2023 The Authors.

The Hidden Source of Testosterone Hypersecretion in a Female-A 30-Year Journey

A Sertoli-Leydig cell tumor (SLCT) is a rare ovarian tumor that often excessively secretes testosterone and its precursor, leading to virilization in females. We present a case of a female patient with persistent, severe hyperandrogenism. Our patient had a history of left oophorectomy due to an ectopic pregnancy and initially presented with amenorrhea at the age of 30. Biochemical evaluations suggested ovarian hyperandrogenism. Despite the absence of an ovarian mass, she underwent a right oophorectomy and remained hyperandrogenic postoperatively. When she established care with our endocrinology clinic at the age of 58, she had more virilizing features and total testosterone levels ranging from 10.1 to 12.0 nmol/L (292-346 ng/dL; normal reference range for women: 0.07-1.56 nmol/L; 2-45 ng/dL). While biochemical evaluations were consistent with tumorous ovarian hyperandrogenism, ultrasound and computed tomography again failed to identify the source. Finally, an 18F-fluorodeoxyglucose-positron emission tomography/computed tomography revealed a mass in the left adnexa, and she underwent removal of the mass. The final pathology confirmed SLCT. The case highlights that SLCT may be small and slow-growing and not readily visible on conventional imaging modalities.

Ovarian Sertoli-Leydig tumor: A tricky tumor case report

INTRODUCTION AND IMPORTANCE

Ovarian Sertoli-Leydig cell tumors (SLCT) are a rare sex cord-stromal tumors, accounting for <0,2 % of all ovarian malignancies. As these tumors are found at an early stage in young women, the whole management dilemma is finding the right balance between a treatment efficient enough to prevent recurrences but that still enables fertility-sparing.

CASE PRESENTATION

We report the case of a 17 years old patient hospitalized in the oncology and gynecology ward of the university hospital Ibn Rochd in Casablanca, presenting a moderately differentiated Sertoli-Leydig cell tumor in the right ovary, our aim is to analyze the clinical, radiological and histological characteristics of this rare tumor that can be tricky to diagnose and review the different management therapies available and the challenges they present.

CLINICAL DISCUSSION

Ovarian Sertoli-Leydig cell tumors (SLCT) are rare sex cord-stromal tumors that should not be misdiagnosed. The prognosis of patients with grade 1 SLCT is excellent without adjuvant chemotherapy. Intermediate and poorly differentiated SLCTs require a more aggressive management. Complete surgical staging and adjuvant chemotherapy should be considered.

CONCLUSION

Our case reaffirms that in the presence of a pelvic tumor syndrome and signs of virilization, SLCT should be suspected. The treatment is essentially surgical, if diagnosed early on, we can offer an effective treatment that preserves their fertility. Efforts should be focused on the creation of regional and international registries of SLCT cases in order to achieve greater statistical power in future studies.

Use of staging for sex cord stromal tumours

PURPOSE OF REVIEW

Sex cord-stromal tumours (SCSTs) are rare ovarian cancers. As in the literature, only small case series or case reports are published, gathering solid evidence about their management is challenging. Surgery plays a pivotal role, and accurate staging is one of the most important prognostic factors. This review focuses on the current evidence for surgical staging in the management of SCSTs.

RECENT FINDINGS

Staging procedures have been inferred by epithelial ovarian cancers; however, they are often only partially performed, and most SCSTs therefore end up incompletely staged, raising the issue of the need for restaging or further treatments. In addition, some parts of the staging procedure have been questioned over the years, and lymphadenectomy is now considered unnecessary for SCSTs.The generally favourable prognosis of SCSTs, the introduction of minimally invasive surgery and fertility-sparing approaches is empowering the question of which staging procedures are beneficial for these patients. We reviewed the role of each staging procedure proposed by the guidelines in light of new scientific updates.

SUMMARY

Surgical staging should always be performed. It includes peritoneal samplings (peritoneal washing, multiple peritoneal biopsies, omental biopsy and biopsy of any suspicious area), whereas lymphadenectomy could be omitted. Laparoscopy may be considered a feasible approach.
