Cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy for recurrent adult granulosa cell tumor: A case report

Is there a role of cytoreductive surgery with HIPEC in recurrent ovarian granulosa cell tumors? An Indian cancer center experience with review of literature

BACKGROUND

Granulosa cell tumors of the ovary represent the most common sex-cord stromal tumors. Though characterized by an indolent course and a good five-year survival rate, they tend to have late recurrences and subsequent poorer survival. The role of hyperthermic intraperitoneal chemotherapy (HIPEC) in women with recurrent granulosa cell tumors with peritoneal dissemination has not been well defined.

METHODS

All patients with adult or juvenile type granulosa cell tumors who underwent cytoreductive surgery with HIPEC with 70 mg/m2 of cisplatin for 60 minutes over a period of four years were retrospectively evaluated. We also performed a review of the literature on similar cases reported.

RESULTS

We identified eight patients with recurrent adult granulosa cell tumors (AGCT) who fulfilled our inclusion criteria. The mean operative duration was 340 minutes, inclusive of the duration of HIPEC. Fifty percent of patients suffered from postoperative morbidity. Grade 4 morbidity was observed in one patient. At a median follow-up of 35 months, four patients experienced disease recurrence. The median disease-free survival was 10 months (range: 6-31 months) and the median overall survival was 11.5 months (range: 7-40 months).

CONCLUSION

Cytoreductive surgery (CRS) and HIPEC provides a unique opportunity for treating peritoneal dissemination in patients with recurrent ovarian AGCTs. This procedure is well tolerated with acceptable morbidity. Prospective studies are warranted to further elucidate the efficacy of this novel therapeutic approach in recurrent ovarian granulosa cell tumors.

A Descriptive Analysis of Patients Undergoing Cytoreductive Surgery for the First Peritoneal Recurrence from Adult Granulosa Cell Tumours: Focus on Disease Distribution, Morphology of Peritoneal Disease and the Role of HIPEC - a Retrospective Study by INDEPSO

The aim of the present study was to report the clinical outcome and factors affecting survival in patients with first recurrence of AGC treated with cytoreductive surgery with or without HIPEC. The second aim was to study the disease distribution in the peritoneal cavity according to the peritoneal carcinomatosis index (PCI) and the morphology of peritoneal deposits. In this retrospective multicentric study, all patients of adult granulosa cell tumor with peritoneal recurrence were treated with CRS with or without HIPEC. Relevant clinical and demographic data were captured. Multivariable logistic regression was performed to evaluate the factors affecting recurrence after CRS ± HIPEC. Factors affecting survival and second recurrences were evaluated in addition to studying the disease distribution at first recurrence. In the period from January 2013 to December 2021, 30 consecutive patients of recurrent adult type granulosa cell tumor of the ovary undergoing CRS ± HIPEC were included in this study. The median follow-up duration was 55 months [12-96 months]. The median rPFS and rOS were both not reached. HIPEC (p = 0.015) was the only factor independently associated with a longer rPFS. CRS with or without HIPEC can be performed with an acceptable morbidity in patients with the first recurrence from adult granulosa cell tumours. The role of HIPEC, patterns of peritoneal spread and impact of other prognostic factors on the treatment outcome all need further evaluation in larger series of patients.

Management of recurrent granulosa cell tumor of the ovary: Contemporary literature review and a proposal of hyperthermic intraperitoneal chemotherapy as novel therapeutic option

Granulosa cell tumors of the ovary (GCT) are the most common type of sex cord stromal tumors. Although most of patients are diagnosed at early stage and has favorable 5-year overall survival rate, 16-23% of GCT ultimately develop recurrent disease. Recurrences are characterized by disseminated peritoneal metastasis. The treatment options include systemic chemotherapy, secondary CRS or palliative localized radiation therapy have not yet standardized due to the rarity of disease. Aggressive CRS followed up by hyperthermic intraperitoneal chemotherapy (HIPEC) has been shown to provide benefit in other peritoneal disease but limited data available for recurrent GCT. We have a case of recurrent Adult-type GCT (AGCT) who was treated with CRS followed by HIPEC with mitomycin C and doxorubicin. The patient has no evidence of recurrence for approximately 11 years. An electronic search of the PubMed database with the following search terms: GCT, HIPEC showed that there were total 21 patients with recurrent GCT treated in seven different studies and 13 of 21 (61.9%) patients had no evidence of disease during follow-up ranging from 6 to 100 months. Three patients (14.2%) died of the disease. Six studies used cisplatin for HIPEC. At least 76.2% (16 of 21, data not available for five patients) had complete cytoreduction with total 16 cases of perioperative complications but no perioperative mortality was observed. Although further investigation is needed, we propose that CRS and HIPEC can be an effective therapeutic option for recurrent GCT at experienced institutions.

Hyperthermic intraperitoneal chemotherapy for women with granulosa cell tumors of the ovary: a systematic review of the literature

Background: Adult and juvenile granulosa cell tumors of the ovary are rare functional sex-cord-stromal ovarian neoplasms characterized by low malignant potential and late relapse. Evidence-based management options for primary and recurrent juvenile (JGCT) and adult (AGCT) granulosa cell tumors are limited and treatment options have not been standardized. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) may be an option to treat these women effectively. Methods: Systematic literature review using PubMed and the Cochrane Central Register of Controlled Trials. Results: No reports of HIPEC among women with a first diagnosis of AGCT were identified. We identified 5 reports on the safety and therapeutic efficacy of CRS and HIPEC in 19 patients with recurrent AGCT and one patient with JGCT. The pooled rate of complete cytoreduction was 95 % (18/19) with 16 % (3/19) severe morbidity and no procedure-related mortality. The median time of follow-up was 30 (range, 3 to 72) months, during which 6/19 (31 %) patients experienced a recurrence and two patients (10 %) died of the disease. Conclusion: CRS and HIPEC are a safe and potentially effective treatment option for selected women with recurrent AGCT limited to the abdomen.
