Therapy of advanced ovarian juvenile granulosa cell tumors

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.

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

AIM

To describe the clinical and pathological characteristics, diagnosis, treatment, and outcomes of juvenile granulosa cell tumor (JGCT).

METHODS

We retrospectively analyzed the data of 19 patients with histopathologically confirmed juvenile granulosa cell tumors treated in two medical centers in Wuhan city of China between 1999 and 2019.

RESULTS

Totally, 19 patients were included during the period. The median age at diagnosis was 8.25 years (range, 0.25-28 years). The most common clinical presentation was abdominal pain, five out of 10 prepubertal children presented with precocious puberty. Three patients underwent radical surgery (including total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and pelvic and para-aortic lymphadenectomy), the other 16 patients had fertility-sparing surgery (cystectomy or ipsilateral salpingo-oophorectomy with or without omentectomy and lymphadenectomy). Eighteen patients had the international federation of gynecology and obstetrics (FIGO) stage I tumors, one patient had FIGO stage II disease. Twelve patients received postoperative adjuvant chemotherapy. The median follow-up time from the time of diagnosis was 35 months (range, 13-250 months). One patient experienced relapse and died of the disease 32 months after the initial diagnosis. Eighteen patients were alive and had not experienced recurrence during the follow-up period. The reproductive age patients that received fertility-sparing surgery had regular menstruation.

CONCLUSIONS

A majority of JGCTs are diagnosed as FIGO stage I tumors and have favorable clinical outcomes. Adjuvant chemotherapy seems to improve outcomes for patients with advanced-stage JGCTs; however, the value of chemotherapy in stage Ic patients is still unknown. Fertility sparing surgery should be considered in young patients who wish to bear children.

Pediatric ovarian Sertoli-Leydig cell tumors with heterologous rhabdomyosarcoma elements: Clinical case series and review of the literature

Sertoli-Leydig cell tumors (SLCTs) are rare ovarian neoplasms in pediatric patients. More exceedingly rare are SLCTs that also contain heterologous rhabdomyosarcoma (RMS) elements. For these patients, there is no standardized treatment. We report four cases of pediatric SLCT with heterologous RMS elements that were successfully treated with surgical resection and adjuvant chemotherapy. All four patients are alive and remain in remission.

A rare case report of ovarian juvenile granulosa cell tumor with massive ascites as the first sign, and review of literature: Case report and review of literature

RATIONALE

Massive ascites as the first sign of ovarian juvenile granulosa cell tumor (JGCT) in an adolescent is an extremely rare, and its clinical features and treatment methods have not been well described.

PATIENT CONCERNS

The clinical characteristics, diagnosis, and treatment methods in a 19-year-old girl who presented with massive abdominal distention and ascites was retrospectively reviewed. Abdominopelvic ultrasonography showed a large amount of ascites. The nature of ascites was exudate. All tumor markers were normal, but ascites and serum tumor CA125 levels were significantly increased. Abdominal CT showed left attachment area teratoma and right attachment area capsule solid change.

DIAGNOSES

Histological and immunohistochemical results were compatible with JGCT. Based on the FIGO classification, the patient with only malignant ascites was categorized into stage IC.

INTERVENTIONS

The patient underwent mass resection with salpingoophorectomy. Following the operation, she received 6 courses of adjuvant chemotherapy with Nedaplatin and Paclitaxel liposome.

OUTCOMES

The patient was followed up postoperatively for 6 months to date without recurrence.

LESSONS

We should be highly vigilant the JGCT with massive ascites as the first clinical manifestation.

Juvenile Granulosa Cell Tumor of the Ovary: A Clinicopathologic Study

STUDY OBJECTIVE

To report on the clinical characteristics and outcome of pediatric patients with juvenile granulosa cell tumor (JGCT) of the ovary. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: Patients with histopathologically confirmed ovarian JGCT diagnosed between 1990 and 2016 were identified. Data on the clinical presentation, surgical management, oncologic management, laboratory investigation, follow-up, and outcome were collected. Tumors were staged according to the International Federation of Gynecology and Obstetrics criteria.

RESULTS

Eight patients were diagnosed with ovarian JGCT during the study period. The median age at presentation was 3 years (range, 0.7-14 years). Precocious puberty was the presenting symptom in all five prepubertal children; abdominal distension due to mass effect was the presenting symptom in three children older than 9 years of age. In patients who had preoperative serologic testing, estradiol (n = 3) and inhibin (n = 3) levels were elevated. Five patients had stage I disease, and three had stage III. All stage I patients underwent salpingo-oophorectomy as the only treatment. Stage III patients received adjuvant chemotherapy. After a median follow-up of 6.2 years, six patients (75%) were alive without evidence of disease. One stage I patient with germline p53 mutation and phosphatase and tensin homolog mutation, died because of subsequent liposarcoma. One patient with stage IIIB disease developed recurrence detected according to an elevated inhibin serum level, and died due to progressive disease despite receiving multiple chemotherapy regimens.

CONCLUSION

Juvenile granulosa cell tumor has a favorable prognosis in patients with stage I disease after surgical resection alone. Adjuvant chemotherapy might be indicated in patients with higher-stage tumors.

Sertoli-Leydig cell tumors: current status of surgical management: literature review and proposal of treatment

To identify the appropriate management we review the current literature on the diagnostic and different surgical procedures to which the patients affected by Sertoli-Leyding cell tumors (SLCTs) were submitted. Through the description of a case report we also propose an interdisciplinary diagnostic approach and a laparoscopic surgical staging, with a long-term follow-up. The analysis shows that pelvic ultrasound is primary diagnostic procedure, and only 36% of publications clearly describe to have performed more specific investigation. The hormone assessment is performed in the presence of specific endocrine symptoms. Laparoscopic approach is chosen by a few surgeon. Laparotomic surgery is preferred based in not recent recommendations for ovarian cancer treatment, although it is demonstrated the efficacy and safety of laparoscopy in the treatment of ovarian epithelial tumors. Different steps that are usually used for oncological ovarian cancer staging are not always performed. Conservative and fertility sparing surgery is commonly accepted, and even preferred due to the young age of patients. In the surgical treatment of SLCTs is necessary to adopt common guidelines, and evenly define the steps that the patient should be submitted. If are observed epithelial cancer oncological principles, laparoscopic surgery should be the approach of choice for these patients.

Massive ascites as the only sign of ovarian juvenile granulosa cell tumor in an adolescent: a case report and a review of the literature

Ovarian neoplasms are relatively rare in childhood and adolescence; only 5% to 8% of the cases are of sex cord stromal origin. Granulosa cell tumors are a group of estrogen producing sex cord stromal tumors of the ovary. They occur in 95% of the cases in adults, and only about 5% of the cases, which differ in histologic characteristics, are of juvenile type. A 13-year-old girl is reported who presented with massive abdominal distention and ascites. An abdominopelvic computed tomography scan showed a predominantly cystic mass lesion with septations arising from the left ovary. All tumor markers were normal, but serum inhibin level was increased. The patient underwent mass resection with salpingoophorectomy. Histopathology was compatible with the juvenile granulosa cell tumor. Interestingly, menarche was started in the patient soon after the surgery. To the best of our knowledge, massive ascites as the only clinical manifestation in the juvenile granulosa cell tumor has not reported as yet.

Management of ovarian and testicular sex cord-stromal tumors in children and adolescents

Pediatric ovarian and testicular sex cord-stromal tumors are distinct from germ cell neoplasms and may present with palpable mass or signs of hormone production. Both may be associated with specific genetic syndromes. Staging for ovarian sex cord-stromal tumors is based on the International Federation of Gynecology and Obstetrics classification for ovarian carcinoma. Treatment for those with high risk disease includes multiagent chemotherapy. Testicular stromal tumors often, though not always, follow a benign course. Additional research will help to define optimal treatment strategies for children with these rare tumors.

Sex cord stromal tumors of the ovary in children: a clinicopathological report from the Italian TREP project

BACKGROUND

Ovarian sex-cord stromal tumors (SCST) are rare in childhood and include a variety of neoplasms with different clinical features and biologic behavior. Aim of the analysis was to report the clinical findings and treatment results of a series of patients with SCST of the ovary, registered in a multi-institutional Italian network on rare tumors in children and adolescent between 2000 and 2009.

METHODS

Data on 23 patients, 5-176 months old, from 13 Centers were reviewed. All patients were grouped on the basis of the results of the first surgical approach, according to the Children Oncology Group staging system. A cisplatin based chemotherapy was recommended in patients with a localized disease, who had undergone an incomplete excision/initial biopsy, and in case of metastatic spread.

RESULTS

A frequent symptom was abdominal pain; 9/23 cases had signs of hormonal secretion and two patients were hospitalized for acute pain following ovarian torsion. Twelve patients had a Juvenile-Granulosa Cell tumor, six a Sertoli-Leydig Cell tumor, three a Fibrothecoma, and two a Sclerosing-Stromal tumor. Twenty-one patients maintained the complete remission (follow-up: 9-91 months), 2 with a ST II Sertoli-Leydig Cell tumor relapsed and one of them died. Immonohistochemical studies could be done in 10 cases.

CONCLUSIONS

Completeness of resection and histology were important prognostic factors; in our series the Sertoli-Leydig Cell tumor was the most aggressive variety. Hormonal signs (precocious puberty, telarca, menarche) were common in younger patients and led to an early diagnosis. Cisplatin based chemotherapy seemed to be effective for locally advanced tumors.

Ovarian juvenile granulosa cell tumors in infants

Juvenile ovarian granulosa cell tumors (JGCTs) are described infrequently in pediatrics, and their finding in prepubertal patients is exceptional. Most of the tumors are benign, but recurrences up to 4 years of follow-up have been described. We present 2 cases of JGCT in infants: 1 with late recurrence of bilateral ovarian JGCT and 1 in a newborn with Ollier disease. Clinical diagnosis and treatment of JGCT are revised.

Adnexal masses in infancy and childhood

The presentation of adnexal masses in childhood differs from that in adult women. Children may present with poorly localized symptoms or precocious puberty. Ovarian cysts occur throughout development; ovarian tumors are less frequent but occur in all age groups. Congenital malformations may present with signs or symptoms of an adnexal mass. Occasionally adnexal findings may suggest the presence of an underlying syndrome. Assessment of the patient's developmental, hormonal, and pubertal status is necessary to ensure an accurate diagnosis. Treatment options must consider risks to ovarian function and future fertility.

Juvenile granulosa cell tumor of the ovary associated with tuberous sclerosis

BACKGROUND

Tuberous sclerosis is a neurocutaneous syndrome characterized by benign tumors that can affect many organs. Juvenile granulosa cell tumors of the ovary are rare neoplasms that typically occur in the first three decades of life and have excellent prognosis for early-staged disease.

CASE REPORT

We report the first case of an 8-year-old white female with tuberous sclerosis and juvenile granulosa cell tumor of the ovary. She presented with a 20 x 22 cm pelvic mass and received a right salpingo-oophorectomy. Three months later, she recurred and underwent a left salpingo-oophorectomy, lymphadenectomy, and omentectomy followed by four cycles of Bleomycin, Etoposide, and Cisplatin chemotherapy. She is currently free of disease 8 years after her recurrence.

CONCLUSION

Treatment options and a review of the literature pertaining to juvenile ovarian granulosa cell tumors and tuberous sclerosis are discussed.

Malignant lesions of the ovary in childhood

Approximately half of all lesions of the ovary in childhood are neoplastic, yet only a small fraction of neoplastic lesions contain malignant elements. Overall, malignancies of the ovary account for 10% of all ovarian masses and 1% of childhood cancers. Primary ovarian malignancies fall into three broad categories based on the cell type of origin. Germ cell tumors predominate and may be further subdivided based on the differentiation of the malignant cells. Epithelial cell tumors, which are most common in adults, and sex-cord stromal tumors each make up 15% of the total in children. Rare malignant lesions and metastatic disease account for the small remaining group of tumors. Regardless of tumor type, the majority of patients present with localized disease, but proper surgical staging is important to determine the need for adjuvant therapy. The development of platinum-based chemotherapeutic regimens has resulted in significant improvements in long-term survival, even for children who present with advanced stage disease.

Ovarian sex cord-stromal tumors--a clinicopathological study of 72 cases from the Kiel Pediatric Tumor Registry

We analyzed 72 patients with ovarian sex cord-stromal tumors (OSCST) registered at the German Pediatric Tumor Registry in Kiel over a 20-year period. Juvenile granulosa cell tumors (JGCT, n=48) were the most frequent histological subtype. In addition, there were 14 Sertoli-Leydig cell tumors, 5 sclerosing stromal tumors, 2 sex cord tumors with annular tubules, 2 thecomas and 1 steroid cell tumor. Stage according to FIGO (International Federation of Gynecologists and Obstetricians) was Ia in 39 patients, Ic in 17 patients, II in 3 patients and III in 1 patient (60 patients with complete data). Compared with adult granulosa cell tumors, JGCT showed pronounced mitotic activity [mean 9.8 mitoses/10 high power field (HPF)], which was significantly higher than in other histological subtypes (2.7/10 HPF, P=0.001). Immunohistochemical analysis revealed frequent coexpression of vimentin (positive in 52/52 examined tumors), cytokeratin (27/33), and inhibin (19/20). Of patients, 12 with Ic or higher stage tumors received adjuvant cisplatinum-based chemotherapy. Event-free survival at 10 years was 0.88 +/- 0.05 (38/43 patients with follow-up data). Outcome significantly correlated with stage and mitotic activity (<20 versus > or =20 mitoses/10 HPF: event-free survival 1.0 versus 0.48 +/- 0.05, P=0.0001). In conclusion, this analysis confirms that the majority of patients with OSCST present at low tumor stage and that prognosis in these patients is excellent. Refractory tumors are characterized by high proliferative activity. Therefore, histopathological evaluation substantially contributes to risk assessment in patients with OSCST and might be useful for therapy stratification in prospective therapeutic protocols.
