Retrospective analysis of clinicopathological characteristics of 19 ovarian juvenile granulosa cell tumor cases

Sex Cord-Stromal Tumors of the Ovary: An Update and Review. Part II - Pure Sex Cord and Sex Cord-Stromal Tumors

We review the time honored but still frequently challenging features of ovarian sex cord-stromal tumors and also emphasize new developments, including unusual morphologic appearances that, despite the relative rarity of many of the tumors, result in a disproportionate number of differential diagnostic problems, variant immunohistochemical profiles, and specific molecular and syndromic associations. These neoplasms are also of historical interest as current knowledge is still based in significant part to the contributions of 2 giants of gynecologic pathology, Dr Robert Meyer and Dr. Robert E. Scully. In part I, we reviewed the pure ovarian stromal tumors. Now, in part II, we present the major clinical, pathologic, and genomic features of pure sex cord and sex cord-stromal tumors.

Laparoscopy for Ovary-Sparing Tumorectomy in Children with Ovarian Tumors: A Clinical Retrospective Analysis

Objective: The aim of this study is to analyze the characteristics of pediatric ovarian tumors (OTs) and evaluate treatment strategies for ovary-sparing tumorectomy (OST). Materials and Methods: Medical records of children from October 2011 to December 2021 were reviewed. Data regarding clinical characteristics, pathological type, and management of OST were analyzed. Results: In total, 61 patients with OTs were screened. The median age was 14.8 ± 3.0 years. The median length and volume of borderline and malignant OTs were larger than those of benign OTs (P < .001 and P = .05, respectively). There was a significant difference in the median OT volume between torsion and nontorsion OTs (P = .04). The overall OST rate was 91.8% (67/73). A total of 53.4% (39/73) lesions were treated with laparoscopic OST. The OT volume was smaller in patients who underwent laparoscopy than in those who underwent laparotomy (P = .04). The probability of intraoperative tumor rupture or spillage was higher during laparoscopy than during laparotomy (P = .02). No significant differences were observed in OT recurrence. Seven patients had borderline and malignant tumors, 3 of whom had stage IA tumors and underwent OST. None of the patients experienced relapse. Conclusions: OT size is a useful reference factor for differential diagnosis and choosing laparoscopic surgery. Intraoperative tumor rupture and spillage of benign tumors during laparoscopy and laparotomy did not seem to be associated with recurrence, and laparoscopic OST was considered safe. Further prospective studies are required to confirm these conclusions.

Bilateral Ovarian Juvenile Granulosa Cell Tumor with Extensive Extracellular Mucin Deposition in an Adolescent: Report of a Rare Presentation with a Comprehensive Review of the Literature

Juvenile granulosa cell tumor (JGCT) of the ovary is an uncommon malignancy, with most cases seen in adolescent girls and young women. The majority of these patients present with unilateral ovarian disease, and to date, bilateral JGCTs have been reported in 10 cases. Although the histopathologic features have been detailed in the published literature, extensive extracellular mucin deposition has been documented in only one case. Herein, we report a 17-year-old adolescent girl with bilateral solid-cystic adnexal masses diagnosed as bilateral JGCT with abundant extracellular mucin deposition on histopathology. The index case highlights a rare clinical and histopathologic presentation of JGCT. Adequate knowledge of such unusual presentations is essential for accurate distinction from other ovarian tumors and appropriate management.

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.

Prognostic predictors in recurrent adult granulosa cell tumors of the ovary: a systematic review and meta-analysis

BACKGROUND

Ovarian adult granulosa cell tumours are low-grade malignant sex cord-stromal neoplasm with a low recurrence rate. Prognostic factors for recurrence include tumor stage, tumor rupture in Stage I neoplasms and the presence of residual tumors after surgery. However, in recurrent tumors, prognostic factors for overall survival (OS) are lacking. In the present paper, we conducted a systematic meta-analysis with the aim to assess prognostic factors for OS in patients with recurrent GCT.

METHODS

Electronic databases were searched for all studies assessing prognostic factors in recurrent adult granulosa cell tumor of the ovary. Student T test, Fisher's exact test and Kaplan-Meier survival analysis with long-rank test were used to assess differences among groups; a p value < 0.05 was considered significant.

RESULTS

Eleven studies analyzing 102 recurrent tumors were included in the systematic review. Tumor stage and localization of recurrent tumors were significantly associated with OS on Kaplan-Meier analysis; Cox regression analysis showed a HR of 0.879 for the stage II, of 3.052 for the stage III, and of 2.734 for stage IV tumor was significantly associated with OS (p = 0.037); observed HRs for abdominal and thoracic locations were of 2.405 and of 4.024, respectively.

CONCLUSIONS

In conclusion, the present article emphasizes the prognostic significance of tumor stage > II and extrapelvic anatomic sites of recurrences in patients with recurrent granuolase cell tumors of the ovary.
