RESUMEN
BACKGROUND: Retrospective data suggest that the incidence of parametrial infiltration is low in patients with early-stage low-risk cervical cancer, which raises questions regarding the need for radical hysterectomy in these patients. However, data from large, randomized trials comparing outcomes of radical and simple hysterectomy are lacking. METHODS: We conducted a multicenter, randomized, noninferiority trial comparing radical hysterectomy with simple hysterectomy including lymph-node assessment in patients with low-risk cervical cancer (lesions of ≤2 cm with limited stromal invasion). The primary outcome was cancer recurrence in the pelvic area (pelvic recurrence) at 3 years. The prespecified noninferiority margin for the between-group difference in pelvic recurrence at 3 years was 4 percentage points. RESULTS: Among 700 patients who underwent randomization (350 in each group), the majority had tumors that were stage IB1 according to the 2009 International Federation of Gynecology and Obstetrics (FIGO) criteria (91.7%), that had squamous-cell histologic features (61.7%), and that were grade 1 or 2 (59.3%). With a median follow-up time of 4.5 years, the incidence of pelvic recurrence at 3 years was 2.17% in the radical hysterectomy group and 2.52% in the simple hysterectomy group (an absolute difference of 0.35 percentage points; 90% confidence interval, -1.62 to 2.32). Results were similar in a per-protocol analysis. The incidence of urinary incontinence was lower in the simple hysterectomy group than in the radical hysterectomy group within 4 weeks after surgery (2.4% vs. 5.5%; P = 0.048) and beyond 4 weeks (4.7% vs. 11.0%; P = 0.003). The incidence of urinary retention in the simple hysterectomy group was also lower than that in the radical hysterectomy group within 4 weeks after surgery (0.6% vs. 11.0%; P<0.001) and beyond 4 weeks (0.6% vs. 9.9%; P<0.001). CONCLUSIONS: In patients with low-risk cervical cancer, simple hysterectomy was not inferior to radical hysterectomy with respect to the 3-year incidence of pelvic recurrence and was associated with a lower risk of urinary incontinence or retention.

OBJECTIVE: The aim of this study was to investigate the relation between the peritoneal cancer index, overall survival, and recurrence free survival, in patients with epithelial ovarian cancer. METHODS: Patients treated at the Gustave-Roussy Institute between December 2004 and November 2017 for advanced epithelial ovarian cancer in complete resection were included. The correlation between the peritoneal cancer index and survival was studied using statistical modeling. Multivariate analysis was performed with a logistic regression model. RESULTS: Of the 351 patients included, 94 (27%) had initial surgery and 257 (73%) had interval surgery. Median follow-up was 52.7 months (range 47.6-63.9). Median peritoneal cancer index was 10 (range 0-32). The linear model best represented the relationship between peritoneal cancer index and overall survival. Patients with neoadjuvant chemotherapy had a greater instantaneous risk of baseline death than those with initial surgery, as well as a more rapid increase in this risk as the peritoneal cancer index increased. Overall survival and recurrence free survival were better in the initial surgery group (103.4 months (79.1-not reached (NR)) vs 66.5 months (59.1-95.3) and 31.8 months (23.7-48.7) vs 25.9 months (23.2-29), respectively). Risk factors for death were body mass index, peritoneal cancer index, and need for neoadjuvant chemotherapy. CONCLUSION: The peritoneal cancer index is a prognostic indicator, but its linear relationship with survival precluded setting a unique peritoneal cancer index cut-off. Moreover, the prognostic impact of peritoneal cancer index was stronger in the setting of neoadjuvant chemotherapy.

BACKGROUND: Knowing the homologous recombination deficiency (HRD) status in advanced epithelial ovarian cancer (EOC) is vital for patient management. HRD is determined by BRCA1/BRCA2 pathogenic variants or genomic instability. However, tumor DNA analysis is inconclusive in 15-19% of cases. Peritoneal fluid, available in > 95% of advanced EOC cases, could serve as an alternative source of cell-free tumor DNA (cftDNA) for HRD testing. Limited data show the feasibility of cancer panel gene testing on ascites cfDNA but no study, to date, has investigated HRD testing. METHODS: We collected ascites/peritoneal washings from 53 EOC patients (19 from retrospective cohort and 34 from prospective cohort) and performed a Cancer Gene Panel (CGP) using NGS for TP53/HR genes and shallow Whole Genome Sequencing (sWGS) for genomic instability on cfDNA. RESULTS: cfDNA was detectable in 49 out of 53 patients (92.5%), including those with limited peritoneal fluid. Median cfDNA was 3700 ng/ml, with a turnaround time of 21 days. TP53 pathogenic variants were detected in 86% (42/49) of patients, all with HGSOC. BRCA1 and BRCA2 pathogenic variants were found in 14% (7/49) and 10% (5/49) of cases, respectively. Peritoneal cftDNA showed high sensitivity (97%), specificity (83%), and concordance (95%) with tumor-based TP53 variant detection. NGS CGP on cftDNA identified BRCA2 pathogenic variants in one case where tumor-based testing failed. sWGS on cftDNA provided informative results even when tumor-based genomic instability testing failed. CONCLUSION: Profiling cftDNA from peritoneal fluid is feasible, providing a significant amount of tumor DNA. This fast and reliable approach enables HRD testing, including BRCA1/2 mutations and genomic instability assessment. HRD testing on cfDNA from peritoneal fluid should be offered to all primary laparoscopy patients.

INTRODUCTION: Refinements of brachytherapy techniques have led to better local control of locally advanced cervical cancer (LACC), especially with the development of image-guided adaptive brachytherapy (IGABT). Data on the efficacy of brachytherapy in cervical cancer spreading to adjacent organs are scarce. We report the experience of our institution in the treatment of these advanced tumors with IGABT. MATERIALS AND METHODS: Medical records of patients treated for a LACC spreading to the bladder and/or rectum between 2006 and 2020 at Gustave Roussy Institute were analyzed. Dosimetric parameters were collected and converted into 2 Gy per fraction equivalent doses, including the minimal dose received by 90% of the high-risk target volume (D90 CTVHR) and intermediate-risk target volume (D90 CTVIR), as well as the dose received by the most exposed 2 cm3 of the organs at risk. A Cox regression model was used to study the potential associations between clinical and dosimetric factors with survival endpoints and fistula formation. RESULTS AND STATISTICAL ANALYSIS: A total of 81 patients were identified. All patients received pelvic+/- para-aortic radiotherapy, 45 Gy in 25 fractions +/- boost to gross lymph nodes. Concomitant platinum-based chemotherapy was administered in 93.8% of cases. The median D90 CTVHR dose was 75.5 GyEQD2 (SD: 10.39 GyEQD2) and median CTVHR volume was 47.6 cm3 (SD: 27.9 cm3). Median bladder and rectal D2cm3 dose were 75.04 GyEQD2 (SD: 8.72 GyEQD2) and 64.07 GyEQD2 (SD: 6.68 GyEQD2). After a median follow-up of 27.62 ± 25.10 months, recurrence was found in 34/81 patients (42%). Metastatic failure was the most common pattern of relapse (n = 25). Use of a combined interstitial/intracavitary technique and D90 CTVHR ≥ 75.1 GyEQD2 were prognostic factors for OS in univariate analysis (HR = 0.24, 95%IC: 0.057-1, p = 0.023; HR = 0.2, 95%IC: 0.059-0.68, p = 0.0025, respectively). In multivariate analysis, a D90 CTVHR ≥ 75.1 GyEQD2 was significant for OS (HR = 0.23; 95%IC: 0.07, 0.78, p = 0.018). The occurrence of vesicovaginal fistula (VVF) was the most frequent pattern of local recurrence (HR = 4.6, 95%CI: 1.5-14, p = 0.01). CONCLUSION: Advances in brachytherapy modalities improved local control and survival while reducing toxicities. Enhancing local control through dose escalation and combined intracavitary/interstitial brachytherapy techniques is a major factor in patients cure probability, together with systemic intensification to better control distant events.

BACKGROUND: Endometrioid borderline ovarian tumor (EBOT) is a rare subtype of borderline ovarian malignancies. This study was designed to determine the prognosis of a series of EBOT. METHODS: This is a retrospective review of patients with EBOT treated in or referred to our institutions and a centralized, histological review by a reference pathologist. Data on the clinical characteristics, management (surgical and medical), and oncologic outcomes of patients were required for inclusion. RESULTS: Forty-eight patients were identified. Median age was 52 years (range 14-89). Fourteen patients underwent a conservative surgery and 32 a bilateral salpingo-oophorectomy (unknown in 2 cases). Two patients had bilateral tumors. Forty-three patients had stage I disease, and five patients had stage II disease (10%). Stromal microinvasion and intraepithelial carcinoma was observed in 6 (12%) and 13 (27%) patients respectively. Endometriosis was histologically associated in 12 patients (25%). Synchronous endometrial disease was found in 7 (24%) of 29 patients with endometrial histological evaluation. The median follow-up was 72 months (range 6-146). Two patients developed a recurrence after cystectomy in form of borderline disease (5%). No death related to EBOT occurred. CONCLUSIONS: Peritoneal restaging surgery should be performed if not realized initially, because 5% of EBOTS are diagnosed at stage II-III. Fertility-sparing surgery seems a safe option in selected patients. Because synchronous endometrial diseases, including endometrial carcinoma are frequent, systematic hysterectomy (or endometrial sampling in case of fertility-sparing surgery) is mandatory. Prognosis is generally excellent. Recurrence is a rare event (6%), but it can occur in the form of invasive disease.

BACKGROUND: Clear cell borderline ovarian tumor (CCBOT) is one of the rarest subtypes of borderline ovarian malignancies. The aim of this study was to determine the prognosis of a series of CCBOT. PATIENTS AND METHODS: A retrospective review of patients with CCBOT treated or referred to our institutions. A centralized histological review by a reference pathologist and data on the clinical characteristics, management, and outcomes of patients were required for inclusion. RESULTS: Nineteen patients were identified. Median age was 62 (range 36-83) years. Four patients underwent a conservative surgery and 14 a bilateral salpingo-oophorectomy +/- hysterectomy (unknown in 1 case). One patient had bilateral tumor, and all cases were stage-I disease. All CCBOTs showed an adenofibromatous pattern. Stromal microinvasion was observed in seven cases and intraepithelial carcinoma in two cases. Endometriosis was histologically associated in one case. The median follow-up was 76 (range 6-231) months. No recurrence occurred. Two patients died of intercurrent disease. CONCLUSIONS: Peritoneal staging procedures should always be associated, but restaging surgery could be omitted if there was no suspicious lesion in the peritoneum during initial surgery, since all patients reported had stage-I disease. Fertility-sparing surgery appears to be a safe alternative in young patients. Synchronous endometrial disorders with atypia are infrequent. Prognosis is generally excellent, and long-term risk of recurrence is low. The two recurrences described in literature occurred in stage-IC diseases, highlighting the importance of avoiding perioperative rupture.

PURPOSE: Kinase inhibitors (KI) and antibodies targeting the VEGF pathway are approved in a broad spectrum of cancers and associated with an increased risk of bleeding and thromboembolic events (TE). The use of direct oral anticoagulants (DOACs) apixaban and rivaroxaban is increasing in cancer patients, but limited data are available for patients receiving anti-VEGF agents. METHODS: To assess safety of DOAC with concomitant anti-VEGF agents, a retrospective chart review of all patients receiving concomitantly DOAC and anti-VEGF agents was performed from 2013 to 2020 in our center. Data on demographics, safety, and time on treatment were collected. Main outcome was safety (bleeding and thromboembolic events). RESULTS: Of 92 patients (median age 66 years (IQR: 59-72)), 40 were treated with KI and 52 with bevacizumab. The most frequent primary tumor sites were colon/rectum (24%), kidney (21%), ovary (13%), lung (11%), soft tissue sarcoma (10%), and thyroid (9%); 2% had brain metastases. Apixaban 5 mg bid (n = 41) or rivaroxaban 20 mg daily (n = 51) were given for TE (65%), atrial fibrillation (32%), or other indications (3%). The median duration of concomitant treatment was 4.8 months (95%CI: 0.7-50.0) with bevacizumab and 11.7 months (95%CI: 0.1-53.8) with KI. Grade ≥ 3 bleeding events occurred in 5 patients (5%): 4 patients receiving bevacizumab (one grade 5 upper digestive tract bleeding and three grade 3 rectal or vaginal hemorrhages) and 1 patient under cabozantinib for kidney cancer with endobronchial metastasis (grade 3 hemoptysis). Grade ≥ 3 TE occurred in 8 patients (9%): 7 patients receiving bevacizumab (including one grade 5 pulmonary embolism), and one patient receiving sunitinib (grade 3 pulmonary embolism). Median time-to-event (bleeding or thrombotic event) was not reached (NR) (95%CI: 76.9-NR) for KI and 86.9 months (95%CI: 42.9-148.0) for bevacizumab. CONCLUSIONS AND RELEVANCE: In our experience, the use of DOAC was safe in selected patients treated with KI, but unclear with bevacizumab. More data are needed to endorse guidelines in this specific group of patients.

BACKGROUND: At diagnosis, tumor-infiltrating lymphocytes (TILs) are prognostic in epithelial ovarian cancer (EOC). We recently demonstrated that neoadjuvant chemotherapy (NACT) significantly increased stromal TILs. Here, we investigated the impact of NACT on immune subpopulations with a particular focus on the balance of immune-reactive to tolerant subpopulations. MATERIALS AND METHODS: Tissue microarrays of EOC (145 pre-NACT, 139 post-NACT) were analyzed for CD3+, CD8+, FOXP3+, CD68+, and CD163+ by immunohistochemistry and CD4+ cells from deduction. Stromal TILs scored as percentage of stromal area, while intra-epithelial TILs scored as number of TILs in contact with tumor cells/HPF. Differences were evaluated by Wilcoxon or Chi square tests, Wilcoxon signed-rank for paired analyses, and cox model for PFS and OS. RESULTS: NACT significantly increased stromal CD3+ (p = 0.003) and CD8+ (p = 0.001) and intra-epithelial CD8+ (p = 0.022) and CD68+ (p = 0.0003) infiltration in unmatched samples and among paired samples for stromal CD3+ and CD8+. Neither CD3+, CD8+, CD4+, and CD68+ nor CD163+ expression correlated with outcome at diagnosis or post NACT. Using median value as a cut-off, high stromal CD8+/FOXP3+ ratio (HR = 0.59; p = 0.017) and high stromal CD3+/FOXP3+ ratio post NACT were associated with prolonged PFS (p = 0.0226). The more the balance shifted in favor of effector versus regulatory TILs, the better the survival. Similarly, high CD68+/CD163+ ratio post NACT improved PFS (p = 0.0445). CONCLUSION: NACT has a significant impact on the balance of immune-reactive to immune-tolerant subpopulations and a high ratio of CD8+/FOXP3+, CD3+/FOXP3+, and CD68+/CD163+ post NACT was significantly associated with improved outcomes. Whether this could select patients for immunotherapy in the post-operative setting should be investigated.

BACKGROUND: Most frequent borderline ovarian tumors are serous and mucinous subtypes. Less frequent borderline diseases are endometrioid, clear-cell, and Brenner tumors (BBOT). Very little is known about the latter subtype, and most studies include very short series or case reports. The aim of this study is to determine the prognosis of a continuous series of BBOT and analyze data published in the literature on this rare entity. PATIENTS AND METHODS: A retrospective review of patients with BBOT treated or referred to our institutions was conducted. A centralized histological review by a reference pathologist and data on the clinical characteristics, management, and outcomes of patients were required for inclusion. RESULTS: Overall, 17 patients were identified. Median age was 62 (range 42-85) years. Six patients underwent unilateral salpingo-oophorectomy, and 11 bilateral salpingo-oophorectomy +/- hysterectomy and/or staging surgery. In total, 16 patients had unilateral tumor, and all patients had stage I disease. Stromal microinvasion was observed in three cases. Median follow-up was 60 months (range 7-118 months). One patient developed a recurrence in contralateral ovary after unilateral salpingo-oophorectomy. One patient had previous history of urothelial tumor. CONCLUSIONS: Peritoneal staging surgery is not required because all patients reported had stage I disease. One recurrence occurred. When reviewing all the 82 cases reported in the literature (including ours), 9% had previous history or synchronous urothelial tumor, suggesting the need to carefully check for urological disease in patients with BBOT.

OBJECTIVE: The aim of this study was to assess the outcomes of a large series of patients treated conservatively for stage II or III serous borderline tumors of the ovary (SBOTs) with a long-term follow-up. METHODS: Patients with SBOTs and peritoneal implants, treated in or referred to our institution, were retrospectively reviewed. Outcomes of patients treated conservatively (preservation of the uterus and at least a part of one ovary) to promote subsequent fertility were specifically analyzed. RESULTS: Between 1971 and 2017, 212 patients were identified and followed-up. Among these patients, 65 underwent conservative treatment; eight patients had invasive implants. Among patients treated conservatively, 38 (58%) patients recurred. Twenty-eight recurrences were observed under the form of borderline tumor on the spared ovary and/or noninvasive implants, but eight patients had a recurrence under the form of invasive disease. Compared with radical surgery, the use of conservative treatment (p < 0.0001) was a prognostic factor on disease-free survival (DFS), but without an impact on overall survival (OS). Nevertheless, three deaths occurred. Twenty-four pregnancies (13 spontaneous) were observed in 20 patients (29 patients wanted to become pregnant). CONCLUSION: In this series collecting the largest number of patients undergoing conservative surgery for stage II/III SBOTs, spontaneous pregnancies can be achieved after conservative treatment of advanced-stage disease, but the recurrence rate is high and three deaths were observed. These patients were spared their fertility but with a high rate of recurrence. Uncertainties regarding the safety of conservative treatment should be exposed to these patients.

BACKGROUND: The identification of factors responsible for false negative (FN) rate at 18F- Fluorodeoxyglucose (FDG) Positron Emission Tomography /Computed Tomography (PET/CT) in para-aortic (PA) lymph nodes in the presurgical staging of patients with locally advanced cervical cancer (LACC) is challenging. The aim of this study was to evaluate the impact of PET/CT technology. METHODS: A total of 240 consecutive patients with LACC (International Federation of Gynecology and Obstetrics, FIGO, stage IB2-IVA) and negative Magnetic Resonance Imaging (MRI) and/or Computed Tomography (CT) and negative 18F-FDG PET/CT in the PA region, undergoing laparoscopic PA lymphadenectomy before chemoradiotherapy were included. The FN rate in patients studied with Time of flight (TOF) PET/CT (TOF PET) or non-Time of flight PET/CT (no-TOF PET) technology was retrospectively compared. RESULTS: Patients presented with FIGO stage IB (n = 78), stage IIA-B (n = 134), stage III (n = 18) and stage IVa (n = 10), squamous cell carcinoma (n = 191) and adenocarcinoma (n = 49). 141/240 patients were evaluated with no-TOF PET/CT and 99/240 with TOF PET/CT. Twenty-two patients (9%) had PA nodal involvement at histological analysis and considered PET/CT FN findings. The FN rate was 8.5% for no-TOF PET and 10% for TOF PET subgroup respectively (p = 0.98). Ninety patients (38%) presented with pelvic node uptakes at PET/CT. The FN rate in the PA region was 18% (16/90) and 4% (6/150) in patients with and without pelvic node involvement at PET/CT respectively (19 vs 3% for no-TOF PET and 17 vs 5% for TOF PET subgroup). CONCLUSIONS: In LACC, FN rate in PA lymph nodes detection is a clinical issue even for modern PET/CT, especially in patients with pelvic uptake. Surgical lymphadenectomy should be performed in case of negative PET/CT at PA level in these patients, while it could be discussed in the absence of pelvic uptake.

BACKGROUND: The disappointing activity of single agent immune-checkpoint inhibitors in epitherlial ovarian cancer (EOC) has been attributed in part to its unique tumor microenvironment (TME). IDO, PDL1, LAG3 and TIM3 have been implicated in the immunotolerance of EOC. We investigated the expression of these co-regulators, their change with neoadjuvant chemotherapy (NACT), and their association with outcome. METHOD: We identified 98 patients with EOC treated with NACT and performed IDO, PDL1, LAG3 and TIM3 immunohistochemistry on samples obtained before and after NACT. The cut-off threshold to consider a positive sample was set at 5%. RESULTS: In our cohort, TIM3 was the most prevalent co-regulator, with more than 75% of the samples being TIM3 positive. In comparison, only 22%, 28% and 17% of the samples were considered IDO, PDL1 and LAG3 positive. More than half of ovarian tumors expressed 2, 3 or even all 4 co-inhibitory molecules. However, biomarkers were not correlated with each other. NACT had a marked impact on immune co-regulator expression with over 70% of patients showing a change in biomarker status from negative to positive or vice versa. There was no significant difference in the pattern of co-regulator expression between platinum-sensitive and resistant patients. Co-expression of multiple inhibitory molecules did not appear to affect overall and progression-free survival. CONCLUSION: TIM3 is the most abundant co-inhibitory molecule in OC and may represent an attractive target. In addition, OC frequently co-expressed 2 or more markers supporting ICI combinatorial approaches. Finally, NACT significantly altered the expression of immunosuppressive molecules suggesting that the choice of ICI combinations should be adapted to the composition of the post-NACT immune TME.

BACKGROUND: Ovarian small cell carcinoma, hypercalcaemic type (SCCOHT) is a rare and lethal disease affecting young women. As histological diagnosis is challenging and urgent, there is a clear need for a robust diagnostic test. While mutations in the chromatin-remodelling gene, SMARCA4, appear to be typical, it may not be feasible routinely to be clinically relevant. METHODS: Previous studies have described the value of SMARCA4 IHC to differentiate SCCOHT from ovarian neoplasms (ON), with similar histologic appearances. We aimed to evaluate its clinical utility among a cohort of 44 SCCOHT and 94 rare ON frequently misdiagnosed as SCCOHT. RESULTS: Forty-three percent (16/36) of SCCOHT had been classified locally as non-SCCOHT confirming the diagnosis challenge. Sensitivity and specificity of SMARCA4 IHC were excellent at 88% and 94%, respectively. In a community setting with a much lower prevalence of the disease, estimated PPV is 40% while NPV remained high at 99%. Finally, among the 16 SCCOHT misclassified locally, SMARCA4 IHC testing would have resulted in corrected diagnosis in 88% of cases. CONCLUSIONS: SMARCA4 IHC is a highly sensitive, and specific test for the diagnosis of SCCOHT and is of huge clinical utility in providing a timely and accurate diagnosis of this challenging disease.

OBJECTIVE: To define a prognostic score based on pretreatment values of leucocyte, platelet and hemoglobin in locally advanced cervical cancer (LACC). MATERIAL AND METHODS: We conducted a prospective study of 238 patients for LACC with negative PET imaging in the para-aortic (PA) area and who were undergoing laparoscopic PA lymphadenectomies. All patients were treated with chemo-radiation and brachytherapy. RESULTS: Patients had clinical International Federation of Gynecology and Obstetrics stages IB2 (n = 76), IIA (n = 13), IIB (n = 122), III (n = 18) or IVA (n = 9). We identified three biological parameters (at the time of diagnosis) with three cut-offs which impacted disease free survival (DFS) and overall survival (OS): <12 g/dL for hemoglobin, >10,000/µL for leucocyte and >300 × 109/L for platelet. A score is calculated, as shown in the table below, by adding the scores of all three biological parameters together (with a maximum score of three). DFS at 36 months was 87.3% [78.3-97.4], 58% [45-74.6], 79.1% [71.1-88], 58% [45-74.6] and 56.8% [37.8-85.4] for scores of 0, 1, 2 and 3 respectively. OS at 36 months was 92.6% [84.9-100], 84% [76.6-92.1], 62.5% [48.9-79.9] and 67% [46.8-96] for scores of 0, 1, 2 and 3 respectively. CONCLUSION: This score includes three biomarkers with easily remembered cut-offs that allow us to identify, at the time of diagnosis, those patients with a high risk of relapse (scores of two or three) and those requiring dose escalation.

BACKGROUND: The aim of this study was to assess prognostic factors and implications on further management in a large series of stage-II or III Atypical Proliferative Serous Tumors (APST) with a long-term follow-up. PATIENTS AND METHODS: Patients with APSTs and peritoneal implants treated in, or referred to, our institution were retrospectively reviewed. Prognostic factors on invasive recurrence, disease-free (DFS) and overall survival (OS) were analyzed. RESULTS: Between 1971 and 2017, 212 patients were identified and followed (33 having invasive implants). After a median follow-up of 115 months, 70 recurrences were observed, 28 of them under the form of invasive disease. DFS at 5 years and 10 years was 73% and 62% respectively. The use of a conservative treatment (HR = 5.5[3.33-9.08], p < .0001), the presence of ≥3 peritoneal sites with implants (HR = 1.65[1.01-2.72], p = .045) were unfavorable prognostic factors for DFS. The presence of ≥3 peritoneal sites with implants (HR = 3.02[0.96-9.53], p = .049) and the presence of stromal microinvasion (HR = 3.19[1.12-9.1], p = .022) were unfavorable prognostic factors for OS. Non-conservative surgery (HR = 7[2.35-20.87], p = .0002), invasive implants (HR = 5.37[1.29-22.26], p = .013), and ≥ 3 peritoneal sites with implants (HR = 3.56 [1.11-11.39], p = .024) were identified as predictors of recurrence in the form of an invasive disease. Invasive implants were not associated with DFS (HR = 1.39[0.77-2.51], p = .27), nor OS (HR = 1.76[0.57-5.47], p = .32). CONCLUSION: After a long-term follow-up, type of peritoneal implants is no longer a prognostic factor for OS. Implants ≥3 peritoneal sites seem to impact significantly OS and then require a specific follow-up in this subgroup of patients.

BACKGROUND: Sertoli-Leydig cell tumors (SLCTs) represent less than 0.5% of ovarian tumors. Because of the rarity of this tumor and its peak in frequency at around 25 years of age, this study aimed to describe SLCT management strategies. OBJECTIVE: The objective of this study was to determine the management (i.e., conservative surgery and adjuvant chemotherapy) of ovarian SLCTs. RESULTS: This retrospective analysis included 23 patients treated for ovarian SLCTs. A centralized pathologic review of the tumors was conducted. Patients were referred to or treated in our institution for an ovarian SLCT between 1994 and 2015. The median age at diagnosis was 33 years (range, 4-82 years). According to the 2014 Federation of Gynecology and Obstetrics classification, tumors were classified as stage Ia (n = 15: well differentiated, n = 1; of intermediate differentiation, n = 8; undifferentiated, n = 4; and undefined, n = 2), stage Ib (n = 1), stage Ic1 (n = 5), stage IIb (n = 1), and stage IIIc (n = 1). Surgery was conservative in 13 patients (Ia, n = 7; Ib, n = 1; Ic1, n = 5) and radical in 10 patients (Ia, n = 8; IIb, n = 1; IIIc, n = 1). Seven patients received adjuvant chemotherapy with a cisplatin-based regimen (Ia, n = 2; Ic1, n = 3; IIb, n = 1) or docetaxel + gemcitabine (IIIc, n = 1). Median follow-up was 61 months (range, 15-252 months). Eight patients experienced a relapse (Ia, n = 2; Ib, n = 1; Ic1, n = 3; IIb, n = 1; IIIc, n = 1). Of these, six had at least one peritoneal carcinomatosis, and four died (Ic1, n = 2; IIb, n = 1; and Ia, n = 1). Two patients had a local relapse (one uterus and one ovary) and survived without disease after relapse treatment. The median time between the initial treatment and relapse was 28 months (range 9-70). CONCLUSION: Conservative surgery was safe for patients with stage Ia ovarian SLCTs. The place of conservative surgery for stage Ic1 remains to be defined. The best chemotherapy regimen remains to be defined. IMPLICATIONS FOR PRACTICE: For stage Ia disease, conservative surgery (in women of reproductive age) was safe and effective for treating ovarian Seroli-Leydig cell tumors. Adjuvant chemotherapy should be proposed for stage Ia when poor prognostic factors are present (poor differentiation, retiform pattern, or heterologous elements). For stage Ic1 and more severe stages, radical surgery and adjuvant chemotherapy should be considered. The combination of bleomycin, etoposide, and cisplatin was the most frequently used regimen, but the best chemotherapy regimen remains to be defined.

BACKGROUND: No series had been reported focusing on the results of fertility-sparing surgery in stage I mucinous ovarian cancers according to histotype (infiltrative vs. expansile). Investigating such outcomes was the aim of the present study. MATERIALS AND METHODS: The present study was a retrospective analysis of patients treated conservatively with preservation of the uterus and contralateral ovary from 1976 to 2016. The pathology of the tumors was reviewed by two expert pathologists according to the 2014 World Health Organization (WHO) classification criteria. Oncologic and fertility results were analyzed. RESULTS: Twenty-one patients fulfilled the inclusion criteria, twelve with expansile and nine with infiltrative cancer. All patients had a unilateral tumor and underwent unilateral salpingo-oophorectomy in one-step (n = 6) or two-step (n = 15) surgeries. All but one had complete peritoneal staging surgery based on cytology, omentectomy, and random peritoneal biopsies. Ten had nodal staging surgery. The International Federation of Gynecology and Obstetrics stages were IA (n = 9), IC1 (n = 6), and IC2 (n = 6); the nuclear grades were grade 1 (n = 9), grade 2 (n = 5), and grade 3 (n = 1). Two patients recurred (one expansile and one infiltrative type) 19 and 160 months after surgery, respectively. One stage IA, nuclear grade 2 expansile tumor recurred on the spared ovary; the patient remains alive. The other stage IA infiltrative tumor recurred as peritoneal spread; the patient is alive with disease. Six patients became pregnant; four with expansile tumors and two with infiltrative tumors. CONCLUSION: The type of mucinous cancer has no impact on the oncologic outcome in this series of patients treated conservatively. Fertility-sparing surgery should be considered for early-stage infiltrative-type tumors. IMPLICATIONS FOR PRACTICE: According to the most recently updated World Health Organization classification guidelines, mucinous cancers should be classified as either expansile or infiltrative. The infiltrative type has a poorer prognosis, but there are no data about the safety of fertility-sparing surgery (FSS) in this context. A collection of 21 cases reviewed by two expert pathologists this study is the first devoted to the conservative treatment of mucinous tumors according to both subtypes. The key result was that the type of mucinous cancer has no impact on the oncologic outcome; thus, FSS may be considered in both subtypes.

BACKGROUND: The present study retrospectively determined the outcomes and prognoses in stage I mucinous ovarian carcinoma according to histological type (ie, expansile or infiltrative). METHODS: A centralized pathologic review of tumors in patients treated from 1976 to 2016 for ovarian mucinous carcinoma was performed by 2 expert pathologists according to the 2014 World Health Organization classification. Only patients with stage I disease were analyzed. Tumors were typed as expansile or infiltrative and oncological issues analyzed. RESULTS: A total of 114 cases were reviewed. Fifty were excluded (stage > I in 30 cases and no accessibility to a pathological review for 20 cases). Thus, 64 patients fulfilled the inclusion criteria: 29 had expansile-type and 35 infiltrative-type disease. The characteristics of both groups of patients were comparable, except the use of nodal staging surgery, which was more frequent in patients with infiltrative type. The International Federation of Gynecology and Obstetrics stages in expansile and infiltrative types were as follows: IA in 13 (45%) and 20 (57%), and IC in 16 (55%) and 15 (43%), respectively. Recurrence occurred in 3 patients with expansile type and 6 patients with infiltrative type. Two cases of expansile recurrence had pelvic recurrence and were salvaged after secondary surgery and chemotherapy, whereas 5 cases of infiltrative recurrence had extrapelvic spread and died from disease or were alive with progressive disease. CONCLUSIONS: Recurrence occurred in both types of stage I mucinous ovarian cancer. However, lethal recurrences were observed mainly in infiltrative type.

Fertility preservation in young patients with cervical cancer is suitable only for patients with good prognostic factors and disease amenable to surgery without adjuvant therapy. Consequently, it is only offered to patients with early-stage disease (stage IB tumours <4 cm), negative nodes, and non-aggressive histological subtypes. To determine whether fertility preservation is suitable, the first step is pelvic-node dissection to establish nodal spread. Tumour size (≤2 cm vs >2 cm) and lymphovascular space invasion status are two main factors to determine the best fertility-sparing surgical technique. In this systematic Review, we assess six different techniques that are available to preserve fertility (Dargent's procedure, simple trachelectomy or cone resection, neoadjuvant chemotherapy with conservative surgery, and laparotomic, laparoscopic and robot-assisted abdominal radical trachelectomy). The choice between the six different fertility preservation techniques should be based on the experience of the team, discussion with the patient or couple, and, above all, objective oncological data to balance the best chance for cure with optimum fertility results for each procedure.

Fertility-sparing treatment (FST) for endometrial carcinoma (EC) is an option for a subgroup of young women with low-risk disease. The low-risk group comprises patients with endometrioid EC stage IA, grade 1, with or without focal lymphovascular invasion. In the era of molecular subtyping, treatment de-escalation for some EC subtypes is recommended. Recommendations for fertility-preserving treatments were developed regardless of the molecular classification of EC. However, few studies have focused on this topic. In this review, we summarize the actual data available in the literature and discuss the impact of some molecular subtypes of FST.
