Heterotopic ovarian transplantation instead hormonal replacement therapy after radical hysterectomy for cervical cancer: case report and review of literature.

PURPOSE: Only a few case reports have described heterotopic ovarian tissue transplantation (OTT) with the only objective of restoring ovarian function. METHODS: Case report and review of the literature for reporting cases of heterotopic OTT with the only aim of restoring ovarian endocrine function. In a cancer survivor woman with a history of hysterectomy and bilateral oophorectomy for cervical cancer and because she poorly tolerated hormone replacement therapy (HRT), we performed a heterotopic OTT in a pelvic subcutaneous "pocket" after an OT cryostorage of 17 years. RESULTS: A cyclic ovarian endocrine function started 3 months after OTT with an immediate patient self-described improvement of her quality of life. A second OTT was performed 19 months after, due to hot flushes recurrence and FSH increase. Despite a cyclic endocrine function, progesterone levels have always been low, resulting in a relative hyperoestrogenism state. CONCLUSION: In the future, the indications of heterotopic OTT could be spread in alternative to HRT. However, our data suggest that the heterotopic graft environment is less favorable to corpus luteum development, and further studies are needed to assay the best site of heterotopic graft, the optimal number of ovarian cortex fragments to graft, and the potential risk of relapse in case of malignant residual disease.

Clinical, pathological, and comprehensive molecular analysis of the uterine clear cell carcinoma: a retrospective national study from TMRG and GINECO network.

BACKGROUND: Uterine clear cell carcinomas (CCC) represent less than 5% of uterine cancers. Their biological characteristics and clinical management remain uncertain. A multicenter study to explore both clinical and molecular features of these rare tumors was conducted. METHODS: This multicenter retrospective national study was performed within the French TMRG (Rare Gynecologic Malignant Tumors) network. Clinical data and, when available, FFPE blocks were collected. Clinical features, treatments, and outcome (progression-free survival (PFS) and overall survival (OS)) were analyzed and correlated to the protein (tissue micro-array), RNA (Nanostring nCounter® technology), and DNA (array-Comparative Genomic hybridization and target-next generation sequencing) levels using the tumor samples available. RESULTS: Sixty-eight patients with uterine CCC were enrolled, 61 from endometrial localization and 5 with cervix localization. Median age at diagnosis was 68.9 years old (range 19-89.7). Most tumors were diagnosed at an early stage (78% FIGO stage I-II). Hysterectomy (performed in 90%) and lymph node dissection (80%) were the most frequent surgical treatment. More than 70% of patients received external beam radiotherapy and 57% received brachytherapy. Nearly half (46%) of the patients received chemotherapy. After a median follow-up of 24.7 months, median PFS was 64.8 months (95 CI [5.3-124.4]) and median OS was 79.7 (IC95 [31.0-128.4]). Low hormone receptor expression (13% estrogen-receptor positive), frequent PI3K pathway alterations (58% PTEN loss, 50% PIK3CA mutations), and P53 abnormalities (41%) were observed. Mismatch repair deficiency was identified in 20%. P16 expression was associated with shorter PFS (HR = 5.88, 95 CI [1.56-25], p = 0.009). Transcriptomic analyzes revealed a specific transcriptomic profile notably with a high expression of immune response-associated genes in uterine CCC displaying a very good overall prognosis. CONCLUSIONS: Uterine CCC reported to be potentially MSI high, hormone receptors negative, and sometimes TP53 mutated. However, some patients with immune response-associated features and better prognosis may be candidate to treatment de-escalation and immunotherapy.

PARP inhibitors (PARPi) prolongation after local therapy for oligo-metastatic progression in relapsed ovarian cancer patients.

BACKGROUND: PARP inhibitors (PARPi) have revolutionized the management of high-grade epithelial ovarian cancer (HGOC) treatment. However, a significant number of patients relapse or progress under PARPi, leading to the introduction of a new line of systemic therapy such as chemotherapy. In patients with a limited number of metastatic sites at progression, -referred to as an oligometastatic progression- a potential indication for local therapy followed by re-introduction or continuation of PARPi treatment rather than initiating a new line of chemotherapy could be proposed. However, the impact of such strategies on progression free survival (PFS) in these patients remains unknown. METHODS: This international multicenter retrospective study evaluated the efficacy of PARPi continuation or re-introduction in patients with HGOC after local treatment for oligometastatic progression. The main objective was to assess PFS under PARPi after local therapy (PFS post-LT). Secondary objectives included safety and overall survival (OS). RESULTS: 74 patients were identified in 20 centers between April 2020 and November 2021. 65% of patients were BRCA mutated and 92% had received ≥2 lines of prior systemic chemotherapy before the initial introduction of PARPi. Main progression sites were lymph nodes (42%), peritoneum (27%), liver (16%), other visceral (16%) and abdominal wall (4%). Local therapies included radiotherapy (45%), surgery (43%), both (7%), percutaneous thermal ablation (4%) or chemoembolization (1%). Median PFS post-LT was 11.5 months [95% CI 7.4; 17.2]. After a median follow up of 14.8 months, 6 patients (8.1%) discontinued PARPi due to toxicity. The 1-year overall survival rate was 90.7% [95% CI 79.1; 96.0]. CONCLUSIONS: With close to one year without progression or introduction of a new line of systemic therapy, this study reports the feasibility and potential benefit of this original strategy in patients with oligometastatic progression under PARPi.

Impact of surgery and chemotherapy in ovarian sex cord-stromal tumors from the multicentric Salomé study including 469 patients. A TMRG and GINECO group study.

OBJECTIVE: Identifying prognostic factors and evaluating the impact of adjuvant chemotherapy in patients with sex cord stromal tumors (SCST) is crucial. In this study, we aimed to address these challenges. METHODS: We conducted a retrospective analysis of data from 13 centers of the French Rare malignant gynecological tumors (TMRG) network. We enrolled 469 adult patients with malignant SCST who received upfront surgery since 2011 to July 2015. RESULTS: 75% were diagnosed with adult Granulosa cell tumors, and 23% had another subtype. With a median follow-up of 6.4 years, 154 patients (33%) developed a first recurrence, 82 (17%) two recurrences, and 49 (10%) three recurrences. Adjuvant chemotherapy was administered in 14.7% of patients at initial diagnosis. In relapse, perioperative chemotherapy was administered in 58.5%, 28.2%, and 23.8% of patients, respectively, in the first, second, and third relapse. In the first-line therapy, age under 70 years, FIGO stage, and complete surgery were associated with longer progression-free survival (PFS). Chemotherapy had no impact on PFS in early-stage disease (FIGO I-II). The PFS was similar using BEP or other chemotherapy regimens (HR 0.88 [0.43; 1.81]) in the first-line therapy. In case of recurrence, PFS was statistically prolonged by complete surgery, but perioperative chemotherapy use did not impact PFS. CONCLUSION: Chemotherapy use did not impact survival in the first-line or relapse setting in SCST. Only surgery and its quality demonstrated benefit for PFS in ovarian SCST in any lines of treatment.

Regorafenib or Tamoxifen for platinum-sensitive recurrent ovarian cancer with rising CA125 and no evidence of clinical or RECIST progression: A GINECO randomized phase II trial (REGOVAR).

OBJECTIVE: To evaluate the efficacy and safety of regorafenib versus tamoxifen in platinum-sensitive ovarian cancer biological recurrence, defined by CA-125 increase without radiological (RECIST criteria) or symptomatic evidence of progression. PATIENTS AND METHODS: 116 patients with platinum-sensitive ovarian cancer presenting an isolated increase of CA-125 were planned to be randomized. Regorafenib was administered orally at 160 or 120 mg daily, 3 weeks on/1 week off or tamoxifen at 40 mg daily, until disease progression or development of unacceptable toxicity. The primary endpoint was Progression-Free Survival, assessed by progression according to RECIST 1.1 or death (by any cause). Secondary endpoints included Overall Survival, Best Response and CA-125 response rate. RESULTS: 68 patients were randomized. Median age was 67 years (range: 30-87). Primary site of cancer was ovarian for most patients (92.6%). Tumors were predominantly serous / (89.7%), high grade (83.6%) and initial FIGO staging was III for 69.6% of the patients. Most (79.4%) patients were included after the first line of platinum-based treatment. After a median follow-up of 32 months, there was no difference of progression-free survival (PFS) between regorafenib and tamoxifen groups (p = 0.72), with median PFS of 5.6 months (CI 90%: 3.84-7.52) for the tamoxifen arm and 4.6 months (CI 90%: 3.65-7.33) for the regorafenib arm. There was also no difference in term of overall survival, best response or CA-125 response, delay to next therapy. Regorafenib presented a less favorable safety profile than tamoxifen, with grade 3/4 events occurring for 90.9% of the patients compared to 54.3% for tamoxifen. The most frequent were cutaneous, digestive, and biological events. Notably, hand-foot syndrome occurred in 36.4% of these patients. CONCLUSION: Regorafenib presented an unfavorable toxicity profile compared to tamoxifen, with no superior efficacy in this population of patients.

Dose-intensive regimen treatment for small-cell carcinoma of the ovary of hypercalcemic type (SCCOHT).

PURPOSE: Small cell carcinoma of the ovary of hypercalcemic type (SCCOHT) is a rare and rapidly lethal disease affecting young women. Cytoreductive surgery associated with chemotherapy followed by a high dose chemotherapy regimen (HDC) demonstrated improved outcomes in a unique prospective and several retrospective studies, and this report aimed to confirm these results in an independent and larger cohort. METHODS: Between 2006 and 2018, we conducted a multicentric prospective study on 44 women diagnosed with SCCOHT. Patients were treated homogeneously with optimal cytoreductive surgery and chemotherapy protocol for four to six cycles (PAVEP). In case of complete response, patients received HDC with stem-cell support, followed by pelvic radiotherapy. The primary endpoint was the event-free survival (EFS) in the per-protocol cohort. Secondary analysis explored the effect of HDC with outcomes. RESULTS: Mean age at diagnosis was 33 years old (range 13.8-75.8). 14 patients presented with stage FIGO I, 21 with stage III and 9 with stage IV. Median follow-up was 53.4 months. 38 patients underwent optimal surgery with up to 6 cycles of PAVEP. 30 received HDC, and 21 pelvic radiotherapy. 21 relapses were reported leading to death for 18 patients. Median EFS in the per-protocol cohort was 18.2 months, and 2-year EFS rate was 40%. HDC was significantly associated with better overall survival (p < .001). Grades 3/4 adverse events were frequent but, in most cases, manageable, although one grade-5 adverse-event occurred during HDC. CONCLUSION: Intensive regimen containing multidrug chemotherapy, HDC and pelvic radiotherapy, for the management of SCCOHT, demonstrated encouraging survival and should be proposed for all patients. However, the significant toxicity cost associated is of concern and it should be restricted to expert centers.

Fertility and prognosis of borderline ovarian tumor after conservative management: Results of the multicentric OPTIBOT study by the GINECO & TMRG group.

OBJECTIVES: Description of fertility and prognosis of patients with borderline ovarian tumor (BOT) treated by fertility-sparing surgery through a longitudinal study from the French national cancer network. METHODS: All consecutive patients diagnosed with BOT from the French National Network dedicated to Ovarian Malignant Rare Tumors from 2010 and 2017 were selected. In 2018, an update was made by sending a questionnaire regarding recurrence and fertility to patients aged under 43 years at diagnosis and treated conservatively. We compared the characteristics of the patients with/without recurrence and with/without live birth. RESULTS: Fifty-two patients aged 18 to 42 years presented a desire of pregnancy. Thirty patients (58%) presented a FIGO IA tumor, and 20 patients were treated by bilateral cystectomies (38%). We observed at least one live birth for 33 patients (63%) and local recurrences in 20 patients (38%). Both recurrence and live birth in 17 patients (33%) were reported, with recurrence occurring before pregnancy, after a second fertility-sparing treatment, in half of the cases. No factors associated with recurrence or live birth in this study were identified. Moreover, in this population, both recurrence and live birth were independent of age, with a linear risk along time. Disease-free survival was worse for patients treated with bilateral cystectomy (n = 20, 38%), with no difference in terms of fertility. CONCLUSION: Two third of the patients experienced life birth after conservation surgery. We did not highlight an age/time from surgery for which the risk of recurrence outweighs the chance of pregnancy and to radicalize surgery. Moreover, almost a quarter of the live birth occurred after recurrence, with no more further event to date in these patients. The results encourage to consider a second fertility-sparing surgery after local borderline recurrence in the case of pregnancy desire. All these decisions must be discussed in specialized multidisciplinary boards.

Non-pegylated liposomal doxorubicin (NPLD, Myocet®) + carboplatin in patients with platinum sensitive ovarian cancers: A ARCAGY-GINECO phase IB-II trial.

BACKGROUND: Carboplatin and pegylated liposomal doxorubicin combination is a standard regimen in platinum-sensitive recurrent ovarian cancer patients. The pegylated liposomal doxorubicin shortage from 2011 to 2013 urged assessment of the efficacy and tolerance of non-pegylated liposomal doxorubicin in combination with carboplatin. METHODS: MYCA was a multicenter 2-step phase Ib-II single arm trial meant to assess the safety and efficacy of carboplatin AUC 5 mg/min.mL combined with non-pegylated liposomal (dose escalation from 40 to 50 mg/m2 during phase Ib step; and 50 mg/m2 during phase II step), every 4 weeks in patients with platinum-sensitive relapse. The primary objective was disease control rate (DCR) at 12 months. RESULTS: From 2012 to 2014, 87 patients were enrolled. They were treated as second (78%) or third line (22%) treatment. Total of 67 patients (78%) completed 6 cycles. G-CSF support was prescribed to 58% patients. The DCR at 12 months was 30.0% (95% CI, 20.3-39.7); the median PFS was 10.0 months (95% CI, 8.6-11.0). The median overall survival was 28.1 months (95% CI, 22.3-32.5); and the objective response rate was 58% (95% CI, 47-68). Grade 3-4 neutropenia, anemia and thrombocytopenia were observed in 17%, 13% and 1%, respectively; febrile neutropenia in 6%. One patient who did not receive GCSF support died from febrile neutropenia. CONCLUSION: Non-pegylated liposomal doxorubicin-carboplatin combination exhibits an acceptable safety profile, with GCSF prophylaxis. Acknowledging the lack of direct comparison, efficacy in terms of 12 month DCR was comparable with standard treatments.

Satisfaction with fertility- and sexuality-related information in young women with breast cancer--ELIPPSE40 cohort.

BACKGROUND: Young breast cancer survivors are often dissatisfied with the information provided on fertility and sexuality. Our aim was to discuss possible contributing factors and to propose strategies to increase patient satisfaction with such information. METHODS: Using the French National Health Insurance System database, we constituted the ELIPPSE40 regional cohort of 623 women, aged 18-40, diagnosed with breast cancer between 2005 and 2011. As of January 2014, 319 women had taken part in the 10-, 16-, 28 and 48-month telephone interviews. Satisfaction with the information provided about the potential impact of cancer and its treatment on fertility and sexuality was assessed at 48 months after diagnosis on 5-point Likert scales. RESULTS: Four years after diagnosis, only 53.0 and 42.6% of women were satisfied with fertility- and sexuality-related information, respectively, without any significant change over the 2009-2014 period (P = 0.585 and P = 0.676 respectively). The two issues were moderately correlated (ρ = 0.60; P <0.001). General satisfaction with medical follow-up was the only common correlate. Irrespective of sociodemographic and medical characteristics, satisfaction with fertility-related information was greater among women with a family history of breast/ovarian cancer who had the opportunity to ask questions at the time of cancer disclosure. Satisfaction with sexuality-related information increased with the spontaneous provision of information by physicians at cancer disclosure. CONCLUSIONS: Promoting both patients' question asking behavior and more systematic information could improve communication between caregivers and young breast cancer survivors and address distinct unmet needs regarding fertility- and sexuality- related information.

Prognostic factors for ovarian epithelial cancer in the elderly: a case-control study.

OBJECTIVES: Ovarian cancer is the leading cause of mortality by gynecologic cancers in Western countries. Many publications have suggested that age may be an independent prognostic factor in ovarian carcinoma. There are only few data concerning the impact of treatments and geriatric features within the elderly population. METHODS/MATERIALS: We collected data of older (≥ 70 years old) patients treated in our institution for an invasive ovarian carcinoma between 1995 and 2011. First we described usual clinical and pathological features for these patients, as well as their outcome. We compared these parameters with that of young (<70 years old) patients treated during the same period. We then observed geriatric features in our set: Eastern Cooperative Oncology Group performance status, number of medications, Charlson index, body mass index, hemoglobin, and glomerular filtration rate. We finally looked for prognostic factors specific of the elderly population. RESULTS: One hundred nine elderly patients were identified and compared with 488 younger cases. There was no difference concerning clinicopathologic data. Surgery was more frequently complete in young women (58% vs 41.7%), and older patients received less chemotherapy courses and less taxanes (38.4% vs 67.1%). Young patients had a longer overall survival (median, 65.2 vs 26.2 months, P = 8.5E-10, log-rank test). Multivariate analyses confirmed that age was an independent prognostic factor and that within the elderly set the International Federation of Gynecology and Obstetrics stage, surgery results, number of chemotherapy cycles administered and performance status had a significant prognostic value. No clear correlation could be observed between geriatric characteristics and treatments administration. CONCLUSIONS: Ovarian cancer prognosis is poorer for older women, but they are more frequently suboptimally treated. No correlation could be observed between geriatric factors and surgery or chemotherapy achievement. Treatment decision should be based on objective geriatric assessment in order to improve outcome in this population.

Endometrioid ovarian carcinoma landscape: pathological and molecular characterization.

Endometrioid ovarian cancers (EOvC) are usually managed as serous tumors. In this study, we conducted a comprehensive molecular investigation to uncover the distinct biological characteristics of EOvC. This retrospective multicenter study involved patients from three European centers. We collected clinical data and formalin-fixed paraffin-embedded (FFPE) samples for analysis at the DNA level using panel-based next-generation sequencing and array-comparative genomic hybridization. Additionally, we examined mRNA expression using NanoString nCounter® and protein expression through tissue microarray. We compared EOvC with other ovarian subtypes and uterine endometrioid tumors. Furthermore, we assessed the impact of molecular alterations on patient outcomes, including progression-free survival (PFS) and overall survival (OS). Preliminary analysis of clinical data from 668 patients, including 86 (12.9%) EOvC, revealed more favorable prognosis for EOvC compared with serous ovarian carcinoma (5-year OS of 60% versus 45%; P = 0.001) driven by diagnosis at an earlier stage. Immunohistochemistry and copy number alteration (CNA) profiles of 43 cases with clinical data and FFPE samples available indicated that EOvC protein expression and CNA profiles were more similar to endometrioid endometrial tumors than to serous ovarian carcinomas. EOvC exhibited specific alterations, such as lower rates of PTEN loss, mutations in DNA repair genes, and P53 abnormalities. Survival analysis showed that patients with tumors harboring loss of PTEN expression had worse outcomes (median PFS 19.6 months vs. not reached; P = 0.034). Gene expression profile analysis confirmed that EOvC differed from serous tumors. However, comparison to other rare subtypes of ovarian cancer suggested that the EOvC transcriptomic profile was close to that of ovarian clear cell carcinoma. Downregulation of genes involved in the PI3K pathway and DNA methylation was observed in EOvC. In conclusion, EOvC represents a distinct biological entity and should be regarded as such in the development of specific clinical approaches.

Homologous Recombination Repair Gene Mutations to Predict Olaparib Plus Bevacizumab Efficacy in the First-Line Ovarian Cancer PAOLA-1/ENGOT-ov25 Trial.

PURPOSE: The PAOLA-1/ENGOT-ov25 trial of maintenance olaparib plus bevacizumab for newly diagnosed advanced high-grade ovarian cancer demonstrated a significant progression-free survival (PFS) benefit over placebo plus bevacizumab, particularly in patients with homologous recombination deficiency (HRD)-positive tumors. We explored whether mutations in non-BRCA1 or BRCA2 homologous recombination repair (non-BRCA HRRm) genes predicted benefit from olaparib plus bevacizumab in PAOLA-1. METHODS: Eight hundred and six patients were randomly assigned (2:1). Tumors were analyzed using the Myriad MyChoice HRD Plus assay to assess non-BRCA HRRm and HRD status; HRD was based on a genomic instability score (GIS) of ≥ 42. In this exploratory analysis, PFS was assessed in patients harboring deleterious mutations using six non-BRCA HRR gene panels, three devised for this analysis and three previously published. RESULTS: The non-BRCA HRRm prevalence ranged from 30 of 806 (3.7%) to 79 of 806 (9.8%) depending on the gene panel used, whereas 152 of 806 (18.9%) had non-BRCA1 or BRCA2 mutation HRD-positive tumors. The majority of tumors harboring non-BRCA HRRm had a low median GIS; however, a GIS of > 42 was observed for tumors with mutations in five HRR genes (BLM, BRIP1, RAD51C, PALB2, and RAD51D). Rates of gene-specific biallelic loss were variable (0% to 100%) in non-BRCA HRRm tumors relative to BRCA1-mutated (99%) or BRCA2-mutated (86%) tumors. Across all gene panels tested, hazard ratios for PFS (95% CI) ranged from 0.92 (0.51 to 1.73) to 1.83 (0.76 to 5.43). CONCLUSION: Acknowledging limitations of small subgroup sizes, non-BRCA HRRm gene panels were not predictive of PFS benefit with maintenance olaparib plus bevacizumab versus placebo plus bevacizumab in PAOLA-1, irrespective of the gene panel tested. Current gene panels exploring HRRm should not be considered a substitute for HRD determined by BRCA mutation status and genomic instability testing in first-line high-grade ovarian cancer.

Whole-genome/exome analysis of circulating tumor DNA and comparison to tumor genomics from patients with heavily pre-treated ovarian cancer: subset analysis of the PERMED-01 trial.

Introduction: The poor prognosis of ovarian carcinoma (OvC) is due to the advanced stage at diagnosis, a high risk of relapse after first-line therapies, and the lack of efficient treatments in the recurrence setting. Circulating tumor DNA (ctDNA) analysis is a promising tool to assess treatment-resistant OvC and may avoid iterative tissue biopsies. We aimed to evaluate the genomic profile of recurrent heavily pre-treated OvC. Methods: We performed tumor panel-based sequencing as well as low-coverage whole-genome sequencing (LC-WGS) of tumor and plasma collected in patients with ovarian cancer included in the PERMED-01 trial. Whole-exome sequencing (WES) data of plasma samples were also analyzed and compared to mutation and copy number alteration (CNA) tumor profiles. The prognostic value [progression-free survival (PFS)] of these alterations was assessed in an exploratory analysis. Results: Tumor and plasma genomic analyses were done for 24 patients with heavily pretreated OvC [67% high-grade serous carcinoma (HGSC)]. Tumor mutation burden was low (median 2.04 mutations/Mb) and the most frequent mutated gene was TP53 (94% of HGSC). Tumor CNAs were frequent with a median of 50% of genome altered fraction. Plasma LC-WGS and WES detected ctDNA in 21/24 cases (88%) with a median tumor fraction of 12.7%. We observed a low correlation between plasma and tumor CNA profiles. However, this correlation was significant in cases with the highest circulating tumor fraction. Plasma genome altered fraction and plasma mutation burden (p = 0.011 and p = 0.041, respectively, log-rank tests) were associated with PFS. Conclusions: Combination of LC-WGS and WES can detect ctDNA in most pre-treated OvCs. Some ctDNA characteristics, such as genome altered fraction and plasma mutation burden, showed prognostic value. ctDNA assessment with LC-WGS may be a promising and non-expansive tool to evaluate disease evolution in this disease with high genomic instability.

Real-World Data on Newly Diagnosed BRCA-Mutated High-Grade Epithelial Ovarian Cancers: The French National Multicenter ESME Database.

BACKGROUND: In spite of the frequency and clinical impact of BRCA1/2 alterations in high-grade epithelial ovarian cancer (HGEOC), real-world information based on robust data warehouse has been scarce to date. METHODS: Consecutive patients with BRCA-mutated HGEOC treated between 2011 and 2016 within French comprehensive cancer centers from the Unicancer network were extracted from the ESME database. The main objective of the study was the assessment of clinicopathological and treatments parameters. RESULTS: Out of the 8021 patients included in the ESME database, 266 patients matching the selection criteria were included. BRCA1 mutation was found in 191 (71.8%) patients, while 75 (28.2%) had a BRCA2 mutation only; 95.5% of patients received a cytoreductive surgery. All patients received a taxane/platinum-based chemotherapy (median = six cycles). Complete and partial response were obtained in 53.3% and 20.4% of the cases, respectively. Maintenance therapy was administered in 55.3% of the cases, bevacizumab being the most common agent. After a median follow up of 51.7 months, a median progression-free survival of 28.6 months (95% confidence interval (CI) [26.5; 32.7]) and an estimated 5-year median overall survival of 69.2% (95% CI [61.6; 70.3]) were reported. Notably, BRCA1- and BRCA2-mutated cases exhibited a trend towards different median progression-free survivals, with 28.0 (95% CI [24.4; 32.3]) and 33.3 months (95% CI [26.7; 46.1]), respectively (p-value = 0.053). Furthermore, five-year OS for BRCA1-mutated patients was 64.5% (95% CI [59.7; 69.2]), while it was 82.5% (95% CI [76.6; 88.5]) for BRCA2-mutated ones (p-value = 0.029). CONCLUSIONS: This study reports the largest French multicenter cohort of BRCA-mutated HGEOCs based on robust data from the ESME, exhibiting relevant real-world data regarding this specific population.

What should be done in terms of fertility preservation for patients with cancer? The French 2021 guidelines.

AIM: To provide practice guidelines about fertility preservation (FP) in oncology. METHODS: We selected 400 articles after a PubMed review of the literature (1987-2019). RECOMMENDATIONS: Any child, adolescent and adult of reproductive age should be informed about the risk of treatment gonadotoxicity. In women, systematically proposed FP counselling between 15 and 38 years of age in case of treatment including bifunctional alkylating agents, above 6 g/m2 cyclophosphamide equivalent dose (CED), and for radiation doses on the ovaries ≥3 Gy. For postmenarchal patients, oocyte cryopreservation after ovarian stimulation is the first-line FP technique. Ovarian tissue cryopreservation should be discussed as a first-line approach in case of treatment with a high gonadotoxic risk, when chemotherapy has already started and in urgent cases. Ovarian transposition is to be discussed prior to pelvic radiotherapy involving a high risk of premature ovarian failure. For prepubertal girls, ovarian tissue cryopreservation should be proposed in the case of treatment with a high gonadotoxic risk. In pubertal males, sperm cryopreservation must be systematically offered to any male who is to undergo cancer treatment, regardless of toxicity. Testicular tissue cryopreservation must be proposed in males unable to cryopreserve sperm who are to undergo a treatment with intermediate or severe risk of gonadotoxicity. In prepubertal boys, testicular tissue preservation is: - recommended for chemotherapy with a CED ≥7500 mg/m2 or radiotherapy ≥3 Gy on both testicles. - proposed for chemotherapy with a CED ≥5.000 mg/m2 or radiotherapy ≥2 Gy. If several possible strategies, the ultimate choice is made by the patient.

Endometrial Carcinoma: Immune Microenvironment and Emerging Treatments in Immuno-Oncology.

Endometrial cancer (EC) can easily be cured when diagnosed at an early stage. However, advanced and metastatic EC is a common disease, affecting more than 15,000 patients per year in the United Sates. Only limited treatment options were available until recently, with a taxane-platinum combination as the gold standard in first-line setting and no efficient second-line chemotherapy or hormone therapy. EC can be split into four molecular subtypes, including hypermutated cases with POLE mutations and 25-30% harboring a microsatellite instability (MSI) phenotype with mismatch repair deficiency (dMMR). These tumors display a high load of frameshift mutations, leading to increased expression of neoantigens that can be targeted by the immune system, including (but not limited) to T-cell response. Recent data have demonstrated this impact of programmed death 1 and programmed death ligand 1 (PD-1/PD-L1) inhibitors on chemo-resistant metastatic EC. The uncontrolled KEYNOTE-158 and GARNET trials have shown high response rates with pembrolizumab and dostarlimab in chemoresistant MSI-high tumors. Most responders experiment long responses that last more than one year. Similar, encouraging results were obtained for MMR proficient (MMRp) cases treated with a combination of pembrolizumab and the angiogenesis inhibitor lenvatinib. Approvals have, thus, been obtained or are underway for EC with immune checkpoint inhibitors (ICI) used as monotherapy, and in combination with antiangiogenic agents. Combinations with other targeted therapies are under evaluation and randomized studies are ongoing to explore the impact of ICI-chemotherapy triplets in first-line setting. We summarize in this review the current knowledge of the immune environment of EC, both for MMRd and MMRp tumors. We also detail the main clinical data regarding PD-1/PD-L1 inhibitors and discuss the next steps of development for immunotherapy, including various ICI-based combinations planned to limit resistance to immunotherapy.

Eribulin Efficacy on Brain Metastases in Heavily Pretreated Patients with Metastatic Breast Cancer.

The onset of brain metastases (BM) is a major turning point during advanced breast cancer (ABC) evolution, with only few treatment options when local therapies have failed. The therapeutic effect of eribulin, a wildly used drug in the treatment of ABC, remains unclear in this setting. PATIENTS AND METHODS: We performed a retrospective observational study to assess eribulin efficacy in patients with ABC who displayed BM at time of eribulin initiation. We collected data from the medical files of all ABC patients who received eribulin at our institution from 2012 until 2020. Our main endpoint was the central nervous system (CNS) progression-free survival. (CNS-PFS). Other evaluation criteria were extra-cranial progression free survival (PFS) and overall survival (OS). RESULTS: Twenty patients with BM monitoring data available were selected out of the 549 who received eribulin during the inclusion period. Fifteen patients (75%) had BM progressive as the best response, three patients (15%) had disease stabilization for more than 6 months and only one patient had a partial response according to RECIST 1.1 criteria. Median CNS-PFS was 3.39 months (95CI (3.02-3.76)). Cox univariate analysis identified molecular subtype as the only prognostic parameter in our cohort, with patients with hormone-receptor positive tumors less likely to experience CNS progression than those with triple-negative MBC (HR = 0.23 (95CI = 0.07-0.80), p = 0.021). Median extra-cranial PFS was 2.67 months (95CI (2.33-3.01)). Median OS was 7.68 months (95CI (0-17.41)). CONCLUSION: Eribulin seems to have only a limited impact on BM evolution. Hormone receptors expression may identify a subset of patients with better BM control.

Advance Approval of Outpatient Chemotherapy via Phone Call Optimizes Healthcare Delivery without Compromising Patient Satisfaction with Care.

Patient satisfaction is linked to the amount of time spent with the physician. At the same time, long waiting times in hospitals are a major source of patient dissatisfaction. The aim of this study was to determine whether advance approval of outpatient chemotherapy (CT) via phone call can optimize healthcare delivery without compromising patient satisfaction with care. Between 2013 and 2016, 343 patients with breast/gynecological cancer scheduled to undergo CT on day 8 and/or day 15 of the CT cycle were enrolled in a before-after study conducted in a French comprehensive cancer center. In the control group, 168 patients received a face-to-face consultation with an oncologist on the day of CT for approval of the upcoming CT session. In the intervention group, 175 patients received a phone call from a healthcare provider the day before CT, where assessment of toxicity from the previous CT session was recorded and submitted to an oncologist for approval of the upcoming CT session. At the end of the 6th CT cycle, patient satisfaction was evaluated using EORTC IN-PATSAT32. A total of 233 questionnaires were analyzed (response rate: 77.7%). Satisfaction with care was similar between the two groups. No differences in perceived health status were observed, but self-reported time in hospital was lower in the intervention group than in the control group (p = 0.007). Advance approval of outpatient CT via phone call is feasible and particularly relevant in the current context of immunotherapy development.

TAKTIC: A prospective, multicentre, uncontrolled, phase IB/II study of LY2780301, a p70S6K/AKT inhibitor, in combination with weekly paclitaxel in HER2-negative advanced breast cancer patients.

BACKGROUND: Hormone-resistant HER2-negative or triple-negative advanced breast cancers (ABC) are routinely treated with paclitaxel chemotherapy. LY2780301 is a dual inhibitor of p70 ribosomal protein S6 kinase and AKT. The TAKTIC study aimed at exploring the combination of paclitaxel and LY2780301 in this population. METHODS: In this multicentric phase Ib/II trial, we enrolled patients with HER2-negative ABC, with (phase IB) or without (phase II) prior to cytotoxic treatment for advanced disease. Oral LY2780301 was administered once daily in combination with intravenous weekly paclitaxel. Primary endpoints were to determine the recommended phase II dose (RP2D) of the combination of LY2780301 with weekly paclitaxel (phase Ib), and to estimate a 6 months objective response rate (ORR) (phase II) in patients with HER2-negative ABC, both in the overall patient population and in cases with activation of the PI3K/AKT pathway (PI3KAKT+). RESULTS: A total of 51 patients were enrolled; RP2D was LY2780301 500 mg QD+ paclitaxel 80 mg/m2. Main drug-related adverse events noted in phase Ib included neuropathy (75% of patients, grade 3-4 in 8%), asthenia (58% of patients, no grade 3-4), and ungual toxicity (50% of patients, grade 3-4 in 25%). They were similar in the phase II part, except that 14% of patients experienced pneumonia (grade 3-4 in 6%). In the phase II part, 6-month ORR in the overall population and in PI3KAKT+ subgroup were, respectively, 63.9% [48.8-76.8] and 55% [35-73.7]. CONCLUSION: Combining LY2780301 and weekly paclitaxel in patients with HER2-negative ABC was feasible with preliminary evidence of efficacy in both the overall population and the PI3KAKT+ subgroup.
