Comparison between laparoscopy and laparotomy in the surgical re-staging of granulosa cell tumors of the ovary

Robotic transumbilical single-site re-staging surgery of ovarian granulosa cell tumor - case report and technical points with video

Introduction

Robotic laparo-endoscopic single-site (R-LESS) surgery is a potential advancement from the conventional single-site surgery in minimally invasive surgery (MIS) management for early ovarian cancer including granulosa cell tumors. This case report details the use of a novel robotic surgical system for a trans-umbilical single-site re-staging procedure to assess its feasibility and safety. It also discusses the technical challenges encountered during omentectomy, one of the most challenging steps of the surgery, since it requires changing of instrument direction from pelvic to abdominal area.

Case presentation

We presented a case of a female in 40 years old who came to our hospital for a re-staging surgery. She underwent open abdominal right ovarian and fallopian tube resection in local hospital, and post-operative pathology reported ovarian granulosa cell tumor. Since she insisted to have MIS, robotic laparo-endoscopic trans-umbilical single-site re-staging surgery was planned for her. The scope of the surgery was total hysterectomy, left ovarian and fallopian tube resection, and omentectomy. The whole surgery took 240 min. Console time was 173 min. Intra-operative bleeding was 50 mL. The patient left our hospital 3 days after surgery with no complications.

Discussion

Ovarian granulosa cell tumor is not common. Staging can be performed under MIS in highly selected patients. During infra-colic omentectomy, spaces were rather narrow for valid movement of robotic arms. To solve this problem, assistant played crucial role for traction and exposure.

Conclusion

To conclude, single-site robotic surgery was feasible for staging of ovarian granulosa cell tumor with highly selected patients.

Effects of different surgical extents on prognosis of patients with malignant ovarian sex cord-stromal tumors: a retrospective cohort study

Malignant ovarian sex cord-stromal tumors are rare neoplasms that account for approximately 5-7% of all ovarian malignancies, and they are primarily treated with surgery. The prognosis of patients with different surgical extents remains controversial. Therefore, the effects of different surgical extents on the prognosis of patients were explored in this retrospective cohort study. Patients with malignant ovarian sex cord-stromal tumors who underwent surgical treatment from January 2000 to December 2019 were selected. Disease-free survival and overall survival rates were calculated by the Kaplan-Meier method and compared by the log-rank test. Prognosis factors were identified by Cox regression analysis. P < 0.05 was considered a statistically significant difference. A total of 278 patients with an average age at onset of 42 (8-78) years old were enrolled. The median follow-up time was 73 months. There was no significant difference in disease-free survival and overall survival rates between patients who underwent fertility-sparing surgery and those who underwent Non-fertility-sparing surgery, and between patients underwent staging surgery and those underwent Non-staging surgery. Age < 40 years (P = 0.024), stage II-III (P = 0.038), a high CA125 level (P = 0.035) and WT-1 (+) (P = 0.016) were independent risk factors for recurrence. In conclusion, different surgical extents have no significant influence on recurrence and survival status of patients with malignant ovarian sex cord-stromal tumors.

[Fertility preservation in female cancer patients.]

In Hungary, an average of 2066 women under the age of 40 are diagnosed with cancer each year according to data from the National Cancer Registry. Approximately two-thirds of these patients require gonadotoxic treatment for their disease, which could potentially reduce their chances of future conception and childbirth. Currently, there are no professional guidelines on fertility preservation in Hungary, however, it is important to inform patients about their options. In our previous paper, we presented the gonadotoxic effects of oncotherapies and the currently available fertility preservation techniques. This second paper provides current treatment methods and recommends fertility preservation techniques in different cancer types. The success of an oncofertility program relies heavily on the effective communication and collaboration between oncologists and reproductive specialists involved in fertility preservation. This paper may be the first step in elaborating a guideline towards improving access to oncofertility services and ultimately improving the quality of life for young cancer survivors in Hungary.

Testosterone elevation in ovarian adult granulosa cell tumor: A case report and review of the literature

RATIONALE

Adult granulosa cell tumors (AGCT) mainly secret estrogen, but few androgens. It is rarer to have amenorrhea and hyperandrogenemia as clinical features. Here, we report a rare case of right side AGCTs with amenorrhea and hyperandrogenemia in a 19-year-old female.

PATIENT CONCERNS

The 19-year-old patient was admitted to our hospital due to amenorrhea for more than 1 year, and discovery of pelvic mass for 4 months. The gynecological ultrasound and computed tomography (CT) cannot define the nature of the mass. Surprisingly, an elevation in testosterone levels was also measured.

DIAGNOSIS AND INTERVENTIONS

The present patient underwent laparoscopic right salpingo-oophorectomy and partial omentectomy and biopsy of the peritoneum.

OUTCOMES

After the surgery, the testosterone value was down to normal. The patient menstrual cramps on August 13, 2021. Her clitoris is smaller than the front. Up to August 1, 2022, there was no obvious sign of recurrence.

LESSONS

Androgen-secreting AGCT is rare. We hope that this case can strengthen gynecologists' early diagnosis and treatment of this disease and improve the prognosis.

Adult ovarian granulosa cell tumors: analysis of outcomes and risk factors for recurrence

OBJECTIVE

Adult granulosa cell tumors represent less than 5% of all ovarian malignancies. The aim of this study was to analyze the clinicopathological parameters and their impact on progression-free and overall survival.

METHODS

Patients with primary adult granulosa cell tumors treated in three international referral centers between July 1999 and December 2018 were included. The following data were anonymously exported from the prospective database: age at diagnosis, International Federation of Gynecology and Obstetrics (FIGO) stage, adjuvant therapy, surgical procedures, progression-free survival, and overall survival. Descriptive statistical analysis regarding tumor and treatment characteristics was performed. Survival analyses included Kaplan-Meier functions and Cox proportional hazard ratios (HR).

RESULTS

A total of 168 patients with primary adult granulosa cell tumors were included. Median age was 50 years (range 13-82). With regard to stage distribution, 54.2% (n=91) of patients were FIGO stage IA, 1.2% (n=2) were stage IB, 26.8% (n=45) were stage IC, and 17.9% (n=30) were FIGO stage II-IV. 66.7% (n=112) of patients underwent surgical restaging, of whom 17.9% (n=20) were moved to a higher stage. In addition, 36 (21.4%) patients underwent fertility-sparing surgery. After a median follow-up of 61 months (range 0-209), 10.7% of patients (n=18) had recurrent disease and 4.8% (n=8) died of disease. Five-year progression-free survival was 86.1% and estimated overall survival was 95.7%. Five-year progression-free survival was worse for patients with advanced stages (FIGO stage IA/B vs IC: HR 5.09 (95% CI 1.53 to 16.9); FIGO stage IA/B vs II-IV: HR 5.62 (95% CI 1.58 to 19.9)). Nineteen patients receiving adjuvant chemotherapy had lower estimated 5-year progression-free survival compared with patients not receiving chemotherapy (49.7% vs 91.1%, p<0.001; HR 9.15 (95% CI 3.62 to 23.1)).

CONCLUSION

The prognosis of patients with primary adult granulosa cell tumors is mainly determined by FIGO stage. The outcome of patients with FIGO stage IC is comparable to those with advanced stages. Fertility-sparing surgery seems to be a safe procedure in stage IA. Our data do not support the use of adjuvant chemotherapy in early and advanced stages of adult granulosa cell tumors.

Surgical staging of apparent early-stage ovarian mucinous carcinoma

Objectives

The aim of the study was to explore the rate of upstaging after complete surgical staging among patients with apparent FIGO stage I ovarian mucinous carcinoma.

Methods

Ovarian mucinous carcinoma patients with surgical treatment at the Peking Union Medical College Hospital between October 2020 and January 1994 were retrospectively reviewed.

Results

In total, 163 patients were included in this study. Surgical restaging was performed in 89 patients after initial incomplete surgical staging, and one-step complete surgical staging was performed in 74 patients. Among these initially incompletely staged patients, residual tumors were found in 16 patients (16/89, 17.9%). Among the 19 patients with apparent FIGO stage IA, no patient was found to have residual tumors after incomplete staging surgery, according to the final pathology result of restaging surgery. Ovarian cystectomy (OR=4.932, 95% CI= 1.347–18.058, P=0.016) was an independent risk factor for residual tumors after incomplete staging surgery. Among all 163 patients, upstaging occurred in 15 patients (15/163, 9.2%). Among 44 apparent FIGO stage IA patients, no patient was upstaged to FIGO II–IVB. Moreover, both a history of ovarian mucinous tumor (OR=4.745, 95% CI= 1.132–19.886, P=0.033) and bilateral ovary involvement (OR=9.739, 95% CI= 2.016–47.056, P=0.005) were independent risk factors for upstaging to FIGO stage II–IVB.

Conclusions

For patients with apparent FIGO stage IA disease, the possibility of residual tumors and upstaging is relatively low. For patients with cystectomy, bilateral mucinous carcinomas, or a history of ovarian mucinous tumors, complete staging surgery maintains greater significance.

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.

Analysis of Outcomes and Prognostic Factors after Fertility-Sparing Surgery in Patients with Early Stage Juvenile Granulosa Cell Tumor of the Ovary: Experience from a Tertiary Center

STUDY OBJECTIVE

The objective of the study was to analyze the oncological outcomes and prognostic factors in patients with early-stage juvenile granulosa cell tumor (JGCT) who underwent fertility-sparing surgery.

DESIGN, SETTING, AND PARTICIPANTS

All patients with early-stage JGCT who underwent fertility-sparing surgery between January 1995 and December 2017 were reviewed retrospectively.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

The risk factors for recurrence and death in patients with early-stage JGCT were identified.

RESULTS

Thirty-five patients were eligible for the current study. The median age was 17 years (range: 4-30 years), and 10 patients were premenarchal. Nine patients were International Federation of Obstetrics and Gynecology stage IA, and 26 were stage IC. Eight subjects underwent complete staging, whereas 28 had no staging at their initial surgery. In those without initial staging, 3 patients who received initial unilateral salpingo-oophorectomy (USO) and 6 with initial cystectomy underwent secondary surgery for staging or USO with staging, respectively. At the time of the secondary staging operation, 1 of the subjects (treated with USO at initial surgery) was found to be stage III and was excluded from this study. Therefore, 8 patients underwent secondary staging surgery performed by laparoscopic surgery, and none of them suffered recurrence during follow-up. Fourteen of the 16 patients with complete staging surgery underwent lymphadenectomy, and none of them had lymph node metastasis. Thirty-one patients received adjuvant chemotherapy after surgery. Eight patients had disease recurrence after a median follow-up time of 51 months (range: 6-229 months), with a median time to recurrence of 4.5 months (range: 2-52 months). Six patients died of their disease. The 5-year disease-free and overall survival rates were 74.8% and 84.3%, respectively. Univariate analysis showed that incomplete staging surgery was associated with increased risk of recurrence (P = 0.029). Adjuvant chemotherapy was not associated with disease-free survival. Four patients had a total of 6 pregnancies, resulting in 6 live births.

CONCLUSION

Complete surgical staging is recommended for early-stage JGCT, but lymph node dissection can be omitted. Laparoscopic restaging surgery is feasible for patients with incomplete staging at initial surgery. However, the prognosis of patients with relapsed JGCT remains poor.

Fertility sparing surgery in sex-cord stromal tumors: oncological and reproductive outcomes

Sex cord stromal tumors are rare neoplasms, frequently diagnosed in young women often as early-stage disease. In patients who desire to preserve fertility, when possible, unilateral salpingo-oophorectomy with peritoneal surgical staging is a safe alternative to radical treatment. In this review, we analyze the available literature on the obstetrical outcomes after fertility-sparing surgery in a total of 255 patients with sex cord stromal tumors. We found that the spontaneous conception rate in granulosa cells tumor is encouraging (88.5%). In particular, juvenile granulosa cell tumors are associated with a more successful pregnancy rate than adult granulosa cells tumors (11/26 (42.3%) in juvenile granulosa cells tumors compared with 28.5% in adult granulosa cell tumors, respectively.) On the other hand, the results of obstetrical outcomes in Sertoli-Leydig cells tumors are less promising (7/36 (19.4%)). Unfortunately, no evidence on this topic is available for sex cord tumor with annular tubules due to the low incidence. Regarding the oncological outcomes of 900 cases of sex cord stromal tumors treated conservatively, data are reassuring with comparable outcomes between patients treated with conservative and radical surgery. Given the limited available data on this rare tumor, further studies are needed to evaluate the safety of conservative approaches and to define the obstetrical outcomes in this patient population.

Oncological Prognosis and Fertility Outcomes of Different Surgical Extents for Malignant Ovarian Sex-Cord Stromal Tumors: A Narrative Review

Background

Malignant ovarian sex-cord stromal tumors (MOSCSTs) are rare neoplasms that account for approximately 5–7% of all ovarian malignancies. The majority (70%) of patients had an early stage; thus, surgery is the predominant treatment. Patients were relatively young at the onset of the tumor. Moreover, the prognosis of patients with this tumor is better than that of malignant epithelial ovarian tumors and tends to recur late with an indolent clinical course. Thus, patients may be more inclined to conservative surgical procedures. There is, however, no objective criterion for selecting a suitable surgical procedure. Clinically, surgical extent depended on the preoperative evaluations, age, and willingness of patients, and gynecologists were relatively subjective when choosing surgery. The prognosis of patients with different surgical extents is still controversial. The review aimed to summarize the impacts of different surgical extents on oncological prognosis and fertility outcomes.

Methods

The literature search was performed in PubMed (https://www.ncbi.nlm.nih.gov/pubmed/), and publications between January 2011 and December 2021 in English including clinical cohort studies and case reports were eligible for inclusion.

Results

We finally identified 12 large-sample retrospective studies and 18 cases of MOSCSTs. The primary surgical procedures include fertility-spring surgery (FSS), total hysterectomy with unilateral or bilateral salpingo-oophorectomy (TAH-USO/BSO), FSS with complete staging procedure, complete staging surgery (CSS), and debulking surgery. FSS includes cystectomy (CYS), unilateral salpingo-oophorectomy (USO) or bilateral salpingo-oophorectomy (BSO) with uterine preservation that allows for potential future assisted reproductive approaches. Complete staging procedure includes peritoneal cytologic examinations, inspections of peritoneal surfaces, random peritoneal biopsies and omentectomy. FSS with complete staging procedure means surgical procedure with uterine preservation and complete staging procedure. And, generally, CSS means TAH-BSO with complete staging procedure.

Conclusion

It can be concluded that USO can be done in young, fertility-desired patients with tumors confined to the ovary but avoid CYS. FSS with complete staging procedure is feasible among stage IC-III patients who have fertility desire. Patients can choose to have a complete surgery once their family is complete or without fertility requirements. CSS is recommended for patients with risk factors such as high stage, poor differentiation, and large tumor size and without fertility desire. A close follow-up is essential.

Robot-assisted laparoscopic debulking surgery for recurrent adult granulosa cell tumors

Despite an often early diagnosis and effective initial surgical management, one third of adult granulosa cell tumors (aGCTs) eventually, and often repeatedly, recurs. Debulking surgery remains the preferred treatment modality for recurrent aGCT, although the risk of intraoperative complications increases with repeated laparotomy. Minimally invasive surgery may limit the risk of complications. We aim to share our initial experience with robotic debulking surgery for recurrent aGCT. Clinical and surgical data of patients with recurrent aGCT who underwent robotic cytoreductive surgery over a three-year period at a tertiary referral center were retrospectively collected and analyzed. Between 2017 and 2020, three patients underwent robotic debulking surgery for recurrent aGCT at our institution. Complete cytoreduction was achieved in all patients. No intraoperative or postoperative complications were reported. This small pilot series at a single academic institution suggests that robot-assisted laparoscopy may be feasible and safe in selected patients with recurrent aGCT. A minimally invasive approach could reduce the complexity of successive surgeries for aGCT relapse.

Disseminated ovarian granulosa cell tumor after laparoscopic surgery: Two case reports

RATIONALE

Granulosa cell tumors (GCT) have an incidence of 0.6 to 0.8/100,000. Short-term relapsed ovarian GCT is extremely rare. Herein, this report aims to present 2 rare cases of disseminated ovarian GCT and analyze the causes of recurrence.

PATIENT CONCERNS

The 2 patients presented with abdominal pain.

DIAGNOSIS

Both the patients were diagnosed with relapsed ovarian GCT (IIIc stage) in the adult type.

INTERVENTIONS

The 2 patients had a medical history of surgery for ovarian GCT by using laparoscopic with power morcellators (LPM). They experienced relapsed ovarian GCT postoperatively. Subsequently, they received a repeated operation through a laparotomy approach. Numerous malignant metastasis neoplasms were detected at the port-sites. Then, tumor resection was performed.

OUTCOMES

The postoperative pathologies of both case 1 and case 2 reported ovarian GCT (IIIc stage) in adult type. The 2 patients presented disease-free survival for more than 33 months follow-up period.

LESSONS

The application of LPM may be a risk factor of disseminated ovarian GCT. However, laparoscopic surgery is still an optimal treatment strategy for ovarian tumors. Besides, gynecologists should comply with the tumor-free principle during surgery.

Stage I juvenile granulosa cell tumors of the ovary: A multicentre analysis from the MITO-9 study

OBJECTIVE

Juvenile type granulosa cell tumor (JGCTs) are extremely rare, mainly diagnosed in young women and pre-pubertal girls at stage I disease. Literature is scanty and guidelines regarding the optimal management are still controversial. The aim of this study is to add on the experience of the MITO group (Multicenter Italian Trials in Ovarian Cancer).

METHODS

Clinicopathological data from patients with stage I JGCTs were retrospectively collected. Descriptive statistics were used to characterize the patient population. Clinicopathological features and treatment variables were evaluated for association with relapse.

RESULTS

Seventeen patients were identified. Surgical approach was laparoscopic and open for 7 (41%) and 10 (59%) patients, respectively. Fertility sparing surgery (FSS) was performed in 15 patients (88%): unilateral salpingo-oophorectomy (USO) in 11 patients, cystectomy with subsequent USO in 2 patients and cystectomy alone in the remaining 2. Adjuvant chemotherapy was given in 2 cases. After a median follow up time of 80 months, no recurrences were registered.

CONCLUSIONS

Given the available data, minimally invasive surgery is safe in stage I JGCTs. Because of the good prognosis and of the young age of patients, FSS can be chosen in most of the cases. The role of cystectomy deserves further validation. The need of adjuvant chemotherapy in stage I disease is still unclear, even if available data does not seem to support treatment over surveillance.

Does uterine preservation affect survival outcomes of patients with stage I ovarian sex cord-stromal cell tumours? A multi-institutional study

OBJECTIVE

Sex cord-stromal tumours of the ovary are relatively uncommon neoplasms that account for 3 % of all ovarian cancers. Uterine preservation with careful staging is achievable; however, conservative surgery remains controversial. This study examined the prognostic effects of uterine preservation in patients with stage I sex cord-stromal tumours.

STUDY DESIGN

This retrospective cohort study was undertaken between January 1986 and February 2019, and the clinicopathological data of 4897 women with malignant ovarian tumours were collected. Seventy-seven patients with stage I sex cord-stromal tumours were eligible for inclusion. The characteristics and survival outcomes of these patients were examined. To investigate the prognostic effects of uterine-preserving surgery, baseline imbalances between patients with and without uterine-preserving surgery were adjusted using an inverse probability of treatment weighting with propensity scores composed of independent clinical variables.

RESULTS

The mean ages of patients in the uterine-preserving surgery and non-uterine-preserving surgery groups were 39.8 and 57.8 years, respectively. After inverse probability of treatment weighting adjustments, no significant differences in overall survival (p = 0.205) or recurrence-free survival (p=0.071) were observed between the uterine-preserving surgery and non-uterine-preserving surgery groups. Estimated 10-year overall survival rates were 98.7 % in the uterine-preserving surgery group and 95.9 % in the non-uterine-preserving surgery group, and 10-year recurrence-free survival rates were 87.2 % in the uterine-preserving surgery group and 78.2 % in the non-uterine-preserving surgery group. Uterine-preserving surgery did not significantly affect the site of tumour recurrence.

CONCLUSION

Uterine-preserving surgery may be a feasible surgical option for patients with stage I sex cord-stromal tumours. Further research is needed to guarantee prognostic accuracy and develop effective therapeutic approaches for sex cord-stromal tumours.
