Prognostic value of circulating tumor DNA at diagnosis and its early decrease after one cycle of neoadjuvant chemotherapy for patients with advanced epithelial ovarian cancer. An ancillary analysis of the CHIVA phase II GINECO trial.

Objective: To evaluate the prognostic impact of circulating tumor DNA (ctDNA) detection at diagnosis (T0) and its early decrease after one cycle (T1) of neoadjuvant chemotherapy (NACT) in patients with advanced epithelial ovarian cancer (EOC) included in the CHIVA trial (NCT01583322).

Methods: Blood samples were collected at T0 and before each administration of NACT. Circulating tumor DNA detection was performed by next-generation sequencing.

The CD47/TSP-1 axis: a promising avenue for ovarian cancer treatment and biomarker research.

Background: Ovarian cancer (OC) remains one of the most challenging and deadly malignancies facing women today. While PARP inhibitors (PARPis) have transformed the treatment landscape for women with advanced OC, many patients will relapse and the PARPi-resistant setting is an area of unmet medical need. Traditional immunotherapies targeting PD-1/PD-L1 have failed to show any benefit in OC.

Trastuzumab deruxtecan in previously treated HER2-positive metastatic or unresectable breast cancer: Real-life data from the temporary use authorization program in France.

Background: Early access program (formerly cohort Temporary Authorization for Use) was granted for trastuzumab deruxtecan (T-DXd) in France based on DESTINY-Breast01 trial which demonstrated its efficacy and safety in HER2-positive metastatic/unresectable breast cancer after ≥2 anti-HER2-based regimens received at metastatic stage.

Methods: This multicenter real-world early access program included HER2-positive metastatic/unresectable breast patients pretreated with at least two lines of anti-HER2 regimens who received T-DXd 5.4 mg/kg intravenously in monotherapy every 3 weeks.

Spatial Profiling of Ovarian Carcinoma and Tumor Microenvironment Evolution under Neoadjuvant Chemotherapy.

Purpose: This study investigates changes in CD8+ cells, CD8+/Foxp3 ratio, HLA I expression, and immune coregulator density at diagnosis and upon neoadjuvant chemotherapy (NACT), correlating changes with clinical outcomes.

Experimental Design: Multiplexed immune profiling and cell clustering analysis were performed on paired matched ovarian cancer samples to characterize the immune tumor microenvironment (iTME) at diagnosis and under NACT in patients enrolled in the CHIVA trial (NCT01583322).

Results: Several immune cell (IC) subsets and immune coregulators were quantified pre/post-NACT.

Neoadjuvant chemotherapy with or without nintedanib for advanced epithelial ovarian cancer: Lessons from the GINECO double-blind randomized phase II CHIVA trial.

Aim: The oral anti-angiogenic therapy nintedanib prolongs progression-free survival (PFS) when combined with chemotherapy after primary surgery for advanced epithelial ovarian cancer. The randomized phase II CHIVA trial evaluated the impact of combining nintedanib with neoadjuvant chemotherapy (NACT) for epithelial ovarian cancer.

Methods: Patients with newly diagnosed unresectable FIGO stage IIIC-IV epithelial ovarian cancer received 3-4 cycles of carboplatin plus paclitaxel every 3 weeks as NACT before interval debulking surgery (IDS), followed by 2-3 post-operative cycles.

Maintenance olaparib plus bevacizumab in patients with newly diagnosed advanced high-grade ovarian cancer: Main analysis of second progression-free survival in the phase III PAOLA-1/ENGOT-ov25 trial.

Background: PAOLA-1/ENGOT-ov25 (NCT02477644) demonstrated a significant progression-free survival (PFS) benefit with maintenance olaparib plus bevacizumab versus placebo plus bevacizumab in newly diagnosed, advanced ovarian cancer. We report the prespecified main second progression-free survival (PFS2) analysis for PAOLA-1.

Methods: This randomised, double-blind, phase III trial was conducted in 11 countries.

Menopausal symptoms in epithelial ovarian cancer survivors: a GINECO VIVROVAIRE2 study.

Objective: We have previously shown that epithelial ovarian cancer (EOC) and its treatments have negative effects on long-term quality of life (QoL) and fatigue. The present multicenter study investigated the main menopausal symptoms and gynecological management of EOC survivors (EOCS).

Methods: 166 patients with relapse-free ≥3 years after the end of treatment attended a consultation with a gynecologist, including a questionnaire related to vasomotor symptoms (VMS) and sexuality, a clinical examination, a blood sample and an osteodensitometry.

Model-Based Quantification of Impact of Genetic Polymorphisms and Co-Medications on Pharmacokinetics of Tamoxifen and Six Metabolites in Breast Cancer.

Variations in clinical response to tamoxifen (TAM) may be related to polymorphic cytochromes P450 (CYPs) involved in forming its active metabolite endoxifen (ENDO). We developed a population pharmacokinetic (PopPK) model for tamoxifen and six metabolites to determine clinically relevant factors of ENDO exposure. Concentration-time data for TAM and 6 metabolites come from a prospective, multicenter, 3-year follow-up study of adjuvant TAM (20 mg/day) in patients with breast cancer, with plasma samples drawn every 6 months, and genotypes for 63 genetic polymorphisms (PHACS study, NCT01127295).

[Breast cancer in young women. Histological and prognostic specificities: how are they different from older women?].

Early-onset of breast cancer (under the age of 40) represents only 7% of all breast cancers, but is the most common cancer in this age group in women. It is also known to be of worse prognosis, with a more aggressive tumoral behavior. The interaction of different prognostic factors contributes to the complexity of this population: tumor burden and biological features (using classical histopronostic features and genomic data) show differences from older women.

UCBG 2-04: Long-term results of the PACS 04 trial evaluating adjuvant epirubicin plus docetaxel in node-positive breast cancer and trastuzumab in the human epidermal growth factor receptor 2-positive subgroup.

Purpose: We conducted a double-randomised phase III trial to evaluate a concomitant taxane-anthracycline regimen in node-positive breast cancer and the efficacy of trastuzumab in the human epidermal growth factor receptor 2 (HER2)-positive subpopulation.

Methods: A total of 3010 patients with node-positive breast cancer were randomly assigned to receive 6 cycles of 500 mg/m of fluorouracil, 100 mg/m of epirubicin and 500 mg/m of cyclophosphamide (FEC) or 75 mg/m of epirubicin and 75 mg/m of docetaxel (ED). Patients with HER2-positive tumours were secondary randomly assigned to either trastuzumab or observation.

Long-term fatigue and quality of life among epithelial ovarian cancer survivors: a GINECO case/control VIVROVAIRE I study.

Background: Few data are available on long-term fatigue (LTF) and quality of life (QoL) among epithelial ovarian cancer survivors (EOCS). In this case-control study, we compared LTF, symptoms and several QoL domains in EOCS relapse-free ≥3 years after first-line treatment and age-matched healthy women.

Patients And Methods: EOCS were recruited from 25 cooperative GINECO centers in France.

[Expectation about maintenance therapy among the GINECO French ovarian cancer cohort from the European NOGGO/ENGOT-ov22 Expression IV survey].

Background: Expression IV survey evaluated the patients' expectations to a maintenance therapy.

Methods: From January 2015 to March 2016, 401 French patients, in first line or recurrent disease, answered a 24-items anonymous questionnaire. The results were specifically analyzed according to the demographic characteristics and treatment lines.

New advances in DPYD genotype and risk of severe toxicity under capecitabine.

Background: Deficiency in dihydropyrimidine dehydrogenase (DPD) enzyme is the main cause of severe and lethal fluoropyrimidine-related toxicity. Various approaches have been developed for DPD-deficiency screening, including DPYD genotyping and phenotyping. The goal of this prospective observational study was to perform exhaustive exome DPYD sequencing and to examine relationships between DPYD variants and toxicity in advanced breast cancer patients receiving capecitabine.

Maintaining professional activity during breast cancer treatment.

The question of returning to work and pursuing professional activity during cancer treatment is an increasingly important consideration. The present work focuses on factors affecting the feasibility of maintaining professional activity during treatment for breast cancer, for women who wished to do so. Written questionnaires were collected from 216 patients between March and November 2012.

UNICANCER-PEGASE 07 study: a randomized phase III trial evaluating postoperative docetaxel-5FU regimen after neoadjuvant dose-intense chemotherapy for treatment of inflammatory breast cancer.

Background: Inflammatory breast cancer (IBC) is a rare and aggressive disease requiring a multimodal treatment. We evaluated the benefit of adding docetaxel-5-fluorouracil (D-5FU) regimen after preoperative dose-intense (DI) epirubicin-cyclophosphamide (EC) and locoregional treatment in IBC patients.

Patients And Methods: PEGASE 07 was a national randomized phase III open-label study involving 14 hospitals in France.

Myotax: a phase II trial of docetaxel plus non-pegylated liposomal doxorubicin as first-line therapy of metastatic breast cancer previously treated with adjuvant anthracyclines.

Aim: Non-pegylated liposomal doxorubicin (NPLD) has demonstrated equivalent antitumour activity to conventional doxorubicin and a significantly lower risk of cardiotoxicity when given as a single agent or in combination with cyclophosphamide. This phase II trial was performed to evaluate the efficacy and the safety of NPLD and docetaxel combination in patients with metastatic breast cancer previously exposed to adjuvant anthracyclines.

Patients And Methods: Thirty-four patients received NPLD 60 mg/m(2) and docetaxel 75 mg/m(2) in a 21-day cycle as first-line therapy of metastatic breast cancer.

[Node negative breast cancer. Beyond international consensus: a pragmatic approach].

Apart from therapeutic advances related to new treatments, our practices in the management of early breast cancer have been modified by to key organizational settings (1) mass screening, substantially altering the presentation and epidemiology of breast cancer and (2) the development of guidelines to ensure that any patient management is in agreement with the demonstrated impact in the adjuvant treatment. In daily practice, the impact of screening and guidelines recommendations has put us now in a paradoxical situation: while the majority of non-metastatic breast cancers treated in the hexagon are node negative, most of the results of clinical studies on chemotherapy and targeted therapies today arise from populations predominantly node positive. Therefore, it seemed legitimate to convene a working group around a reflection on the directions of adjuvant chemotherapy in a growing node negative population in order to better respond to the questions of the field oncologists, trying to address the discrepancies between different existing guidelines.

Gemcitabine-oxaliplatin combination for ovarian cancer resistant to taxane-platinum treatment: a phase II study from the GINECO group.

Advanced ovarian carcinoma in early progression (<6 months) (AOCEP) is considered resistant to most cytotoxic drugs. Gemcitabine (GE) and oxaliplatin (OXA) have shown single-agent activity in relapsed ovarian cancer. Their combination was tested in patients with AOCEP in phase II study.

Randomized multicenter phase II study of larotaxel (XRP9881) in combination with cisplatin or gemcitabine as first-line chemotherapy in nonirradiable stage IIIB or stage IV non-small cell lung cancer.

Introduction: This randomized phase II study investigated the efficacy and safety of a new taxane, larotaxel (XRP9881), in combination with either cisplatin or gemcitabine in the first-line treatment of patients with nonirradiable stage IIIB or stage IV non-small cell lung cancer to select the combination having the most promising antitumor activity.

Methods: Patients received either larotaxel (50 mg/m) as a 1-hour infusion, followed by a 1-hour infusion of cisplatin (75 mg/m), every 3 weeks (arm A), or gemcitabine (800 mg/m) as a 30 minute infusion, on days 1 and 8, and larotaxel (60 mg/m) as a 1-hour infusion, on day 8 (following gemcitabine), every 3 weeks (arm B). The primary end point was the objective response rate (per-protocol population).
