Neoadjuvant and adjuvant pembrolizumab in advanced high-grade serous carcinoma: the randomized phase II NeoPembrOV clinical trial.

This open-label, non-comparative, 2:1 randomized, phase II trial (NCT03275506) in women with stage IIIC/IV high-grade serous carcinoma (HGSC) for whom upfront complete resection was unachievable assessed whether adding pembrolizumab (200 mg every 3 weeks) to standard-of-care carboplatin plus paclitaxel yielded a complete resection rate (CRR) of at least 50%. Postoperatively patients continued assigned treatment for a maximum of 2 years. Postoperative bevacizumab was optional. The primary endpoint was independently assessed CRR at interval debulking surgery. Secondary endpoints were Completeness of Cytoreduction Index (CCI) and peritoneal cancer index (PCI) scores, objective and best response rates, progression-free survival, overall survival, safety, postoperative morbidity, and pathological complete response. The CRR in 61 pembrolizumab-treated patients was 74% (one-sided 95% CI = 63%), exceeding the prespecified ≥50% threshold and meeting the primary objective. The CRR without pembrolizumab was 70% (one-sided 95% CI = 54%). In the remaining patients CCI scores were ≥3 in 27% of the standard-of-care group and 18% of the investigational group and CC1 in 3% of the investigational group. PCI score decreased by a mean of 9.6 in the standard-of-care group and 10.2 in the investigational group. Objective response rates were 60% and 72%, respectively, and best overall response rates were 83% and 90%, respectively. Progression-free survival was similar with the two regimens (median 20.8 versus 19.4 months in the standard-of-care versus investigational arms, respectively) but overall survival favored pembrolizumab-containing therapy (median 35.3 versus 49.8 months, respectively). The most common grade ≥3 adverse events with pembrolizumab-containing therapy were anemia during neoadjuvant therapy and infection/fever postoperatively. Pembrolizumab was discontinued prematurely because of adverse events in 23% of pembrolizumab-treated patients. Combining pembrolizumab with neoadjuvant chemotherapy is feasible for HGSC considered not completely resectable; observed activity in some subgroups justifies further evaluation to improve understanding of the role of immunotherapy in HGSC.

Preoperative neutrophil/lymphocyte ratio as prognostic factor in epithelial ovarian cancer / Cociente neutrófilos/linfocitos preoperatorio como factor pronóstico en el cáncer epitelial de ovario.

Objectives: To determine if there is an association between the neutrophil to lymphocyte ratio (NLR) and prognosis in patients with epithelial ovarian cancer (EOC) diagnosed and treated in a Spanish population. Material and methods: Retrospective cohort of patients with epithelial ovarian cancer who had neutrophil and lymphocyte values in complete blood count before the histopathological diagnosis and survival of at least three months, in an intermediate complexity hospital. Convenience sampling. Measured variables included age, menopausal stage, parity, International Federation of Gynecology and Obstetrics (FIGO) stage, treatment type, residual tumor, lymph node involvement, presence of ascites, cytology, histologic type, differentiation grade, and CA-125 values. Additionally, outcomes, overall survival, disease/progression-free survival were also measured. Bivariate inferential and Cox regression analyses were performed. Results: Out of 78 candidates, 60 women with EOC were included. Of them, 24 (40%) had a low NLR (≤ 2,9) while 36 (60%) had a high NLR (> 2,9). An association was found between high NLR levels and suboptimal cytoreductive surgery. High NLR ratios were associated with lower overall survival (Hazard ratio (HR): 4.1; 95% CI: 1.4-11.8) and lower 5-year disease-free survival (HR: 2.6; 95% CI: 1.2-5.7). Conclusions: A plasma neutrophil to lymphocyte ratio of more than 2.9 was associated with poor prognosis in patients with epithelial ovarian cancer in our setting. There is a need to establish the optimal cut-off point and conduct prospective studies with larger patient numbers in order to support this information.

Objetivos: evaluar si hay asociación entre los valores del cociente plasmático neutrófilos/ linfocitos (NLR) y el pronóstico en pacientes con cáncer epitelial de ovario (CEO) diagnosticadas y tratadas en una población española. Materiales y métodos: cohorte retrospectiva de pacientes con cáncer epitelial de ovario que tuvieran un recuento de neutrófilos y linfocitos en hemograma previo al diagnóstico histopatológico en un hospital de nivel medio de complejidad y posterior sobrevida de, al menos, 3 meses. Muestreo por conveniencia. Se midieron: edad, estado menopáusico, paridad, estadio Federación International de Ginecología y Obstetricia (FIGO), tipo de tratamiento, tumor residual, afectación ganglionar, presencia de ascitis, citología, tipo histológico, grado de diferenciación y cifras de CA-125; como desenlaces, sobrevida global y sobrevida libre de enfermedad o progresión. Análisis inferencial bivariado y por regresión de Cox. Resultados: de 78 candidatas, ingresaron 60 mujeres con CEO. De ellas, 24 (40%) presentaron un NLR bajo (≤ 2,9) y 36 (60 %) elevado (> 2,9). Se encontró asociación entre los niveles altos de NLR y cirugía citoreductora subóptima. Los niveles altos de NLR se asociaron a menor sobrevida global (Hazard ratio (HR): 4,1; IC 95%: 1,4-11,8) y menor sobrevida libre de enfermedad a los 5 años (HR:2,6; IC 95 %: 1,2-5,7). Conclusiones: un cociente plasmático neutrófilos/linfocitos mayor de 2,9 se asoció a un mal pronóstico en pacientes con cáncer epitelial de ovario en nuestro medio. Se necesita determinar el punto de corte óptimo y realizar estudios prospectivos con mayor número de pacientes que avalen esta información.

Preoperative Immune Cell Dysregulation Accompanies Ovarian Cancer Patients into the Postoperative Period.

Ovarian cancer (OC) poses a significant global health challenge with high mortality rates, emphasizing the need for improved treatment strategies. The immune system's role in OC progression and treatment response is increasingly recognized, particularly regarding peripheral blood mononuclear cells (PBMCs) and cytokine production. This study aimed to investigate PBMC subpopulations (T and B lymphocytes, natural killer cells, monocytes) and cytokine production, specifically interleukin-1 beta (IL-1ß), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10), interleukin-12 (IL-12), and tumor necrosis factor alpha (TNFα), in monocytes of OC patients both preoperatively and during the early postoperative period. Thirteen OC patients and 23 controls were enrolled. Preoperatively, OC patients exhibited changes in PBMC subpopulations, including decreased cytotoxic T cells, increased M2 monocytes, and the disbalance of monocyte cytokine production. These alterations persisted after surgery with subtle additional changes observed in PBMC subpopulations and cytokine expression in monocytes. Considering the pivotal role of these altered cells and cytokines in OC progression, our findings suggest that OC patients experience an enhanced pro-tumorigenic environment, which persists into the early postoperative period. These findings highlight the impact of surgery on the complex interaction between the immune system and OC progression. Further investigation is needed to clarify the underlying mechanisms during this early postoperative period, which may hold potential for interventions aimed at improving OC management.

Management strategy for children with ovarian immature teratoma: results from a tertiary pediatric oncology center.

OBJECTIVES: We present an Egyptian study on pediatric ovarian immature teratomas (ITs), aiming to clarify our treatment strategy selection. METHODS: A retrospective review of all children with pure ovarian ITs who were treated at our institution between 2008 and 2023. The analysis included clinical characteristics, tumor staging according to Children's Oncology Group (COG), grading based on the Norris system, management, and outcomes. RESULTS: Thirty-two patients were included, with a median age of 9 years. All patients underwent primary surgery. Unilateral salpingo-oophorectomy was performed in 31 patients. Surgical staging was completed in all patients. Based on COG staging, there were 28 patients (87.5%) stage I, 1 (3%) stage II, and 3 (9.5%) stage III. According to Norris classification, 16 patients (50%) were classified as grade I, 9 (28%) grade II, and 7 (22%) grade III. All patients in stage I were treated using surgery-alone approach, whereas the remaining four (12.5%) received adjuvant chemotherapy. Five patients in stage I had gliomatosis peritonei (GP), and none of them underwent extensive surgery. At a median follow-up of 86 months, two patients had events. The first patient (stage III/grade I) developed IT relapse on the operative bed, and the second (stage I/grade I) had a metachronous IT on the contralateral ovary. Both patients were successfully managed with surgery followed by second-line chemotherapy. Five-year overall survival and event-free survival for all patients were 100% and 93.4%, respectively. CONCLUSIONS: Surgery-alone strategy with close follow-up achieves excellent outcomes for localized ovarian ITs in children, irrespective of the Norris grading or the presence of GP. However, adjuvant chemotherapy is questionable for patients with incompletely resected or locally advanced tumors, and its role requires further evaluation through prospective multicentric studies with a larger sample size.

Uterine tumors resembling ovarian sex cord tumors: A retrospective analysis of 7 cases from a single institution.

To investigate the clinicopathological features, diagnosis, surgical treatment and prognosis of uterine tumors similar to ovarian sex cord tumors (UTROSCT). The clinical data, surgical approach, histopathological, and immunohistochemical features of 7 cases of UTROSCTs were retrospectively reviewed and followed up. All 4 patients were premenopausal women. The most common clinical presentation was menorrhagia (n = 4) followed by postmenopausal lower abdominal mass (n = 2) and postmenopausal bleeding (n = 1). Gynecological ultrasonography suggested uterine fibroids in 4 cases, adenomyosis with uterine fibroids in 2 cases, and an intrauterine mass in 1 case. Pelvic MRI was performed preoperatively in only 2 cases, and both indicated uterine fibroid degeneration, including 1 patient with suspected malignancy. Preoperative serum tumor markers were measured in 6 patients, and only 1 patient had elevated CA125 levels, up to 158 U/mL. Total hysterectomy with bilateral adnexectomy or salpingectomy was the most common treatment pattern (n = 6). The tumors were located within the myometrium (n = 4), submucosa (n = 1), and isthmus to external cervical os (n = 1), with a range of 2 to 12 (mean = 8) cm. Edema and degeneration were observed in 2 cases, and necrosis in 1 case. Postoperative follow-up ranged from 31 to 82 (mean = 43) months. Unfortunately, 1 patient died at 54 months of follow-up without undergoing hysterectomy. The remaining 6 cases showed no tumor recurrence or metastasis after surgery. Histological examination revealed a tumor composed of epithelioid tumor-like cells arranged in cords, trabeculae, and nests. All 7 tumors showed expression of 2 sex cord differentiation markers. Furthermore, all tumors expressed the smooth muscle marker, while epithelial marker CK (4/7). endometrial stromal marker CD10(0/7). The Ki-67 proliferation index was found to be <5% (5/7). The option of total hysterectomy may be considered for women who do not have any fertility requirements. However, for young women who desire to maintain their reproductive capacity, surgery to preserve the uterus may be an alternative, although it necessitates careful postoperative monitoring. In terms of follow-up monitoring, MRI is more suitable than ultrasound. The diagnosis of UTROSCT heavily relies on histopathological examination and immunohistochemical analysis.

Feasibility of transperineal minimal invasive surgery when performing sacrectomy for advanced primary and recurrent pelvic malignancies.

BACKGROUND: This study aimed to clarify the efficacy and safety of minimally invasive transabdominal surgery (MIS) with transperineal minimal invasive surgery (tpMIS) for sacrectomy in advanced primary and recurrent pelvic malignancies. METHODS: Using a prospectively collected database, we retrospectively analyzed the clinical, surgical, and pathological outcomes of MIS with tpMIS for sacrectomies. Surgery was performed between February 2019 and May 2023. The median follow-up period was 27 months (5-46 months). RESULTS: Fifteen consecutive patients were included in this analysis. The diagnoses were as follows: recurrent rectal cancer, n = 11 (73%); primary rectal cancer, n = 3 (20%); and recurrent ovarian cancer, n = 1 (7%). Seven patients (47%) underwent pelvic exenteration with sacrectomy, six patients (40%) underwent abdominoperineal resection (APR) with sacrectomy, and two patients (13%) underwent tumor resection with sacrectomy. The median intraoperative blood loss was 235 ml (range 45-1320 ml). The postoperative complications (Clavien-Dindo grade ≥ 3a) were graded as follows: 3a, n = 6 (40%); 3b, n = 1 (7%); and ≥ 4, n = 0 (0%). Pathological examinations demonstrated that R0 was achieved in 13 patients (87%). During the follow-up period, two patients (13%) developed local re-recurrence due to recurrent cancer. The remaining 13 patients (87%) had no local disease. Fourteen patients (93%) survived. CONCLUSIONS: Although the patient cohort in this study is heterogeneous, MIS with tpMIS was associated with a very small amount of blood loss, a low incidence of severe postoperative complications, and an acceptable R0 resection rate. Further studies are needed to clarify the long-term oncological feasibility.

A pre-operative scoring model to estimate the risk of blood transfusion over an ovarian cancer debulking surgery (BLOODS score): a Memorial Sloan Kettering Cancer Center Team Ovary study.

OBJECTIVES: To develop a pre-operative tool to estimate the risk of peri-operative packed red blood cell transfusion in primary debulking surgery. METHODS: We retrospectively reviewed an institutional database to identify patients who underwent primary debulking surgery for ovarian cancer at a single center between January 1, 2001 and May 31, 2019. Receiver operating characteristic curve and area under the receiver operating characteristic curve (AUC) were calculated. Five-fold cross-validation was applied to the multivariate model. Significant variables were assigned a 'BLOODS' (BLood transfusion Over an Ovarian cancer Debulking Surgery) score of +1 if present. A total BLOODS score was calculated for each patient, and the odds of receiving a transfusion was determined for each score. RESULTS: Overall, 1566 patients met eligibility criteria; 800 (51%) underwent a peri-operative blood transfusion. Odds ratios (OR) were statistically significant for American Society of Anesthesiologists scores of 3 and 4 (OR 1.34, 95% confidence interval (95% CI) 1.09 to 1.63), pre-operative levels of cancer antigen 125 (CA125) (OR 2.43, 95% CI 1.98 to 2.99), platelets (OR 1.59, 95% CI 1.45 to 1.74), obesity (OR 0.76, 95% CI 0.60 to 0.96), presence of carcinomatosis (OR 2.45, 95% CI 1.93 to 3.11), bulky upper abdominal disease (OR 2.86, 95% CI 2.32 to 3.54), pre-operative serum albumin level (OR 0.31, 95% CI 0.24 to 0.40), and pre-operative hemoglobin level (OR 0.56, 95% CI 0.51 to 0.61). The corrected AUC was 0.748 (95% CI 0.693 to 0.804). BLOODS scores of 0 and 5 corresponded to 11% and 73% odds, respectively, of receiving a peri-operative blood transfusion. CONCLUSIONS: We developed a universal pre-operative scoring system, the BLOODS score, to help identify patients with ovarian cancer who would benefit from surgical planning and blood-saving techniques. The BLOODS score was directly proportional to the American Society of Anesthesiologists score, presence of upper abdominal disease, carcinomatosis, CA125 level, and platelets level. We believe this model can help physicians with surgical planning and can benefit patient outcomes.

Ovarian sclerosing stromal tumor mimicking malignancy: case series and literature review.

BACKGROUND: Sclerosing stromal tumors (SST) are rare ovarian neoplasms that often appear as solid unilateral tumors of the ovary with no specific clinical or radiological presentation. The definitive treatment is surgical removal. CASE PRESENTATION: Our article presents four cases of female patients with sclerosing stromal ovarian tumor with clinical characteristics mimicking malignant ovarian lesions. Interestingly, two of our cases had elevated levels of inhibin B. All patients were treated with surgery (oophorectomy) and had no disease recurrence. CONCLUSION: Tumors' macroscopic features are usually non-specific and often suggestive of possible malignancy, therefore diagnosis is always based on histopathological report.

Ovarian teratoma in a Swiss mountain dog.

A Swiss mountain dog, ~3 y old, was brought to a veterinary clinic because of a progressive enlargement of the abdomen. Upon clinical examination, a large mass was detected. After surgical extraction, the mass was confirmed to be a large ovarian teratoma. The weight of the tumor was > 16% of the dog's overall body weight. The dog recovered fully after surgery. The observations from this case suggest that, although teratomas are rare, prompt and accurate diagnosis is necessary to prevent further growth of these masses and to ensure positive outcomes.

Tératome ovarien chez un chien de montage suisse. Un chien de montagne suisse âgé d'environ 3 ans a été présenté dans une clinique vétérinaire en raison d'une augmentation de volume progressive de l'abdomen. Lors de l'examen clinique, une grosse masse a été détectée. À la suite du retrait chirurgical, la masse a été confirmée comme étant un large tératome ovarien. Le poids de la masse tumorale était > 16 % du poids total du chien. Le chien a récupéré complètement après la chirurgie. Les observations à partir de ce cas suggèrent, bien que les tératomes soient rares, un diagnostic rapide et exact est nécessaire pour prévenir une croissance ultérieure de ces masses et assurer une issue positive.(Traduit par Dr Serge Messier).

Pseudomyxoma peritonei leading to "jelly belly" abdomen: a case report and review of the literature.

BACKGROUND: Pseudomyxoma peritonei is an infrequent condition with a global annual incidence of only one to two cases per million people. Mucinous neoplasms, widespread intraperitoneal implants, and mucinous ascites characterize it. Currently, most clinicians misdiagnose this condition, which leads to delayed management. CASE PRESENTATION: A 44-year-old North Indian female presented with a 1.5-month history of an abdominal lump. Physical examination revealed a sizeable abdominopelvic mass at 36 weeks. Contrast-enhanced computed tomography showed a massive multiloculated right ovarian cystic mass measuring 28 × 23 × 13 cm with mild ascites and elevated carcinoembryonic antigen levels (113.75 ng/ml). A provisional diagnosis of ovarian mucinous neoplasm was made, for which the patient underwent laparotomy. Intraoperatively, there were gross mucinous ascites, along with a large, circumscribed, ruptured right ovarian tumor filled with gelatinous material. The appendicular lump was also filled with mucinous material along with the omentum, ascending colon, right lateral aspect of the rectum, splenic surface, and small bowel mesentery. Cytoreductive surgery was performed along with an oncosurgeon, including total abdominal hysterectomy with bilateral salpingoophorectomy, omentectomy, right hemicolectomy, lower anterior resection, ileo-transverse stapled anastomosis with proximal ileal loop diversion stoma, excision of multiple peritoneal gelatinous implants, and peritoneal lavage. Histopathology and immunohistochemistry confirmed the presence of intestinal-type mucinous carcinoma. Postoperatively, the patient was given six cycles of chemotherapy. She tolerated it without any specific morbidity and had an uneventful recovery. Postoperative follow-up at 15 months revealed normal tumor marker levels and abdominal computed tomography findings and no signs suggestive of local recurrence or distal metastases. CONCLUSIONS: Pseudomyxoma peritonei is a rare disease that is frequently misdiagnosed in the preoperative phase. Therefore, radiologists and clinicians should maintain a high index of suspicion for accurate diagnosis and multidisciplinary management.

Genetic Profiling of Sebaceous Carcinoma Arising from an Ovarian Mature Teratoma: A Case Report.

Ovarian mature teratomas (OMTs) originate from post-meiotic germ cells. Malignant transformation occurs in approximately 1-2% of OMTs; however, sebaceous carcinoma arising from OMTs is rare. This is the first report of a detailed genomic analysis of sebaceous carcinoma arising from an OMT. A 36-year-old woman underwent evaluation for abdominal tumors and subsequent hysterectomy and salpingo-oophorectomy. Pathologically, a diagnosis of stage IA sebaceous carcinoma arising from an OMT was established. Eight months post-surgery, the patient was alive without recurrence. Immunohistochemically, the tumor was negative for mismatch repair proteins. A nonsense mutation in TP53 (p.R306*) and a deletion in PIK3R1 were identified. Single nucleotide polymorphisms across all chromosomes displayed a high degree of homozygosity, suggestive of uniparental disomy. Herein, the OMT resulting from the endoreduplication of oocytes underwent a malignant transformation to sebaceous carcinoma via TP53 as an early event and PIK3R1 as a late event.

Oncological outcomes of fertility-sparing surgery versus radical surgery in stage - epithelial ovarian cancer: a systematic review and meta-analysis.

BACKGROUND: The oncological outcomes of fertility-sparing surgery (FSS) compared to radical surgery (RS) in patients with stage I epithelial ovarian cancer (EOC) remain a subject of debate. We evaluated the risk ratios (RRs) for outcomes in patients with stage I EOC who underwent FSS versus RS. METHODS: We conducted a systematic search of PubMed, Web of Science, and Embase for articles published up to November 29, 2023. Studies that did not involve surgical procedures or included pregnant patients were excluded. We calculated the RRs for disease-free survival, overall survival, and recurrence rate. The quality of the included studies was assessed using the Cochrane Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) tool. The meta-analysis was registered on PROSPERO (CRD42024546460). RESULTS: From the 5,529 potentially relevant articles, we identified 83 articles for initial screening and included 12 articles in the final meta-analysis, encompassing 2,906 patients with epithelial ovarian cancer. There were no significant differences between the two groups in disease-free survival (RR [95% confidence interval {CI}], 0.90 [0.51, 1.58]; P = 0.71), overall survival (RR [95% CI], 0.74 [0.53, 1.03]; P = 0.07), and recurrence rate (RR [95% CI], 1.10 [0.69, 1.76]; P = 0.68). In sensitivity analyses, the significant difference was observed only for overall survival (before exclusion: RR [95% CI], 0.74 [0.53-1.03], P = 0.07; after exclusion: RR [95% CI], 0.70 [0.50-0.99]; P = 0.04). CONCLUSIONS: This is the first and only individual patient data meta-analysis comparing disease-free survival, overall survival, and recurrence rate of patients with early-stage epithelial ovarian cancer undergoing FSS and RS. FSS was associated with similar disease-free survival and risk of recurrence as RS. We hypothesized that the decreased overall survival in the FSS group could not be attributed to distant metastases from epithelial ovarian cancer.

Splenectomy as a part of cytoreductive surgery in ovarian cancer: systematic review and meta-analysis.

OBJECTIVE: The role of splenectomy on cytoreductive surgery in patients with ovarian cancer remains controversial. We conducted this meta-analysis to evaluate the safety and impact of survival outcome of splenectomy in patients with ovarian cancer. METHODS: In this meta-analysis we analyzed studies published in PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), International Clinical Trials Registry Platform (ICTRP), and Clinical Trials. gov that appeared in our search from inception to November 10, 2023. RESULT: This meta-analysis included 10 studies, totaling 6297 patients, comprising one prospective and nine retrospective analyses. The results indicated no significant disparity in overall survival and mortality (OR 1.14, 95% CI 0.69 to 1.87, p=0.62) between the splenectomy cohort and the no splenectomy (required) cohort. Furthermore, relative to the no splenectomy (required) cohort, the splenectomy group showed a heightened incidence of overall post-operative complications (odds ratio (OR) 1.66, 95% CI 1.65 to 2.61, p=0.03), an extended duration of hospitalization (mean difference (MD) 2.88 days, 95% CI 2.09 to 3.67), an increased interval from surgery to the initiation of adjuvant chemotherapy (MD 4.44 days, 95% CI 2.41 to 6.07, p<0.0001), and a greater probability of undergoing reoperation (OR 4.7, 95% CI 1.91 to 11.55, p=0.0007). However, concerning the occurrence of specific post-operative complications such as anastomotic leakage (OR 0.97, 95% CI 0.33 to 2.84, p=0.95), pancreatic fistula (OR 3.25, 95% CI 0.63 to 16.7, p=0.16), abdominal abscess (OR 1.75, 95% CI 0.25 to 12.33, p=0.57), sepsis (OR 1.46, 95% CI 0.77 to 2.77, p=0.25), and thrombotic events (OR 1.82, 95% CI 0.93 to 3.57, p=0.08), no significant differences were observed between the two cohorts. CONCLUSION: Splenectomy does not impact the overall survival and mortality of patients with ovarian cancer. Thus, it can be considered an acceptably safe procedure to obtain optimal cytoreduction. However, caution should be taken when selecting patients for splenectomy because it is associated with an increased incidence of overall post-operative complications, prolonged hospital stays, delayed initiation of adjuvant chemotherapy, and an increased probability of requiring subsequent surgical interventions.

Cytoreductive surgery plus chemotherapy versus chemotherapy alone for recurrent epithelial ovarian cancer.

OBJECTIVES: This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To evaluate the benefits and harms of secondary CRS and chemotherapy in comparison to chemotherapy alone for women with platinum-sensitive recurrent epithelial ovarian cancer.

The experiance of tertiary center for adult granulosa cell tumor: which factors predict survival?

BACKGROUND: This retrospective study aims to evaluate the clinical course and long-term outcomes of patients diagnosed with adult granulosa cell tumors (AGCT). METHODS: The study analyzed a cohort of 112 AGCT patients with a median follow-up of 87 months. Data regarding disease-free survival (DFS), overall survival (OS), recurrence rates, and prognostic factors were collected and analyzed. Surgical interventions, including lymphadenectomy and cytoreductive surgery, were assessed for their impact on outcomes. RESULTS: The study revealed favorable long-term outcomes, with a 5-year DFS of 85% and a 10-year DFS of 83%. Additionally, a 5-year OS of 100% and a 10-year OS of 96% were observed. Recurrence occurred in 13.4% of cases, with advanced stage and positive peritoneal cytology identified as independent poor prognostic factors for DFS. Lymph node involvement was rare, and routine lymphadenectomy did not improve outcomes. Conservative surgery showed comparable DFS rates to definitive surgery in early-stage disease. However, cytoreductive surgery was crucial for advanced and recurrent tumors, with complete tumor resection enhancing survival outcomes. CONCLUSION: The study underscores the importance of vigilant follow-up and individualized treatment strategies for AGCT patients. Despite the retrospective nature of the analysis, the substantial patient cohort and meticulous surgical interventions contribute valuable insights into AGCT management. Prospective multicenter studies are warranted to further elucidate prognostic factors and optimize treatment approaches for this rare malignancy.

Surgical management of ovarian masses in children and adolescents: experience of an academic institution in France.

PURPOSE: Surgical management of ovarian masses in girls still challenging. The aim of the study is to report an 8-year experience in managing children with ovarian masses, and to demonstrate the advantages and the limitations of laparoscopy for such lesions. METHODS: Data of girls aged less than 18 years operated because of an ovarian mass between January 2015 and February 2023 were retrospectively reviewed. Patients were divided into two groups: group A including children operated by laparoscopy, and Group B of patients who underwent open surgery. RESULTS: Eighty-eight children were enrolled. Laparoscopy was performed in 56 patients (63.6%). Group A patients had smaller tumor size (53.6±38.5 vs. 122.2±75.4 mm, P<0.0001), shorter operative time (50.4±20.3 vs. 71.5±36.5 min, P = 0.004), reduced length of hospital stay (1.4±1.1 vs. 3±2.3 days, P<0.0001), and absence of postoperative complications. Only 3 cases (5.7%) of recurrence were seen exclusively within patients followed for benign tumors during a mean follow-up period of 4.6±3 years. CONCLUSION: Laparoscopy should be done in benign ovarian lesions or/and if a torsion is seen. For tumors at high risk of malignancy, laparoscopy can be performed to establish a clear macroscopic diagnosis, for staging of the disease, and resection of small tumors. Conversion to open surgery is indicated in case of doubt.
