RESUMO

Concomitant chemotherapy with cisplatin (100 mg/m every 3 weeks) improves outcome for high-risk patients in the postoperative setting and for inoperable disease. Toxicity is increased. Other schemes of potentiation are sometimes used to reduce toxicity, but efficiency is diminished. Cetuximab also improves outcome, but there has been no direct comparison with cisplatin. Immunotherapy is currently being evaluated in association with radiation therapy. Trials are ongoing to evaluate the impact of de-escalation for human papillomavirus-positive patients. The association of docetaxel, cisplatin, and 5-fluorouracil is the standard of induction; it is also the standard treatment for laryngeal preservation. Many trials have attempted to compare the concomitant approach with the sequential treatment; none have managed to show a difference between the two. After induction chemotherapy, there is still no standard of potentiation of radiotherapy.

RESUMO

Chemotherapy is the only option of treatment for most patients presenting with a recurrent and/or metastatic head and neck squamous cell carcinoma. The triple association of cisplatin, 5-fluorouracile, and cetuximab is still the current standard for fit patients. Other schemes are currently being compared with this protocol in ongoing trials and the association of cisplatin, docetaxel, and cetuximab appears to be the most efficient. The human papilloma virus is very likely a favorable prognostic factor. Immunotherapy with nivolumab or pembrolizumab is now a new standard of treatment in second line after yielding an improvement in overall survival, but predictive markers of efficacy are needed to refine the selection of patients. The combination of paclitaxel and buparlisib appears to be promising.

RESUMO

BACKGROUND: Cancer treatment is constantly evolving toward a more personalized approach based on clinical features, imaging, and genomic pathology information. To ensure the best care for patients, multidisciplinary teams (MDTs) meet regularly to review cases. Notwithstanding, the conduction of MDT meetings is challenged by medical time restrictions, the unavailability of critical MDT members, and the additional administrative work required. These issues may result in members missing information during MDT meetings and postponed treatment. To explore and facilitate improved approaches for MDT meetings in France, using advanced breast cancers (ABCs) as a model, Centre Léon Bérard (CLB) and ROCHE Diagnostics cocreated an MDT application prototype based on structured data. OBJECTIVE: In this paper, we want to describe how an application prototype was implemented for ABC MDT meetings at CLB to support clinical decisions. METHODS: Prior to the initiation of cocreation activities, an organizational audit of ABC MDT meetings identified the following four key phases for the MDT: the instigation, preparation, execution, and follow-up phases. For each phase, challenges and opportunities were identified that informed the new cocreation activities. The MDT application prototype became software that integrated structured data from medical files for the visualization of the neoplastic history of a patient. The digital solution was assessed via a before-and-after audit and a survey questionnaire that was administered to health care professionals involved in the MDT. RESULTS: The ABC MDT meeting audit was carried out during 3 MDT meetings, including 70 discussions of clinical cases before and 58 such discussions after the implementation of the MDT application prototype. We identified 33 pain points related to the preparation, execution, and follow-up phases. No issues were identified related to the instigation phase. Difficulties were grouped as follows: process challenges (n=18), technological limitations (n=9), and the lack of available resources (n=6). The preparation of MDT meetings was the phase in which the most issues (n=16) were seen. A repeat audit, which was undertaken after the implementation of the MDT application, demonstrated that (1) the discussion times per case remained comparable (2 min and 22 s vs 2 min and 14 s), (2) the capture of MDT decisions improved (all cases included a therapeutic proposal), (3) there was no postponement of treatment decisions, and (4) the mean confidence of medical oncologists in decision-making increased. CONCLUSIONS: The introduction of the MDT application prototype at CLB to support the ABC MDT seemed to improve the quality of and confidence in clinical decisions. The integration of an MDT application with the local electronic medical record and the utilization of structured data conforming to international terminologies could enable a national network of MDTs to support sustained improvements to patient care.

RESUMO

BACKGROUND/AIM: Olaparib was approved in 2014 by the European Medicines Agency (EMA) as maintenance treatment for patients with breast cancer gene (BRCA)-mutated platinum-sensitive relapsed high-grade epithelial ovarian cancer (EOC) following the results of the Study 19. We present the results of a national real-world study on the effectiveness of olaparib in relapsed BRCA-mutated EOC patients. PATIENTS AND METHODS: Patients with EOC, peritoneal, and/or fallopian-tube cancer treated with olaparib in a French Center between May 2014 and March 2017 were included. The primary end-point of the study was progression-free survival. RESULTS: Of the 128 patients analyzed, 89 were treated according to the EMA label. The median progression-free survival was 17.0 months. The most common treatment-related toxicity was fatigue. Treatment-related myelodysplastic syndrome (n=5) and a second cancer (n=1) were diagnosed. CONCLUSION: In this real-life setting, olaparib confirmed its efficacy and safety profile, as previously shown in clinical trials.

RESUMO

BACKGROUND: a specific subset of metastatic triple-negative breast cancers (mTNBC) is characterized by homologous recombination deficiency (HRD), leading to enhanced sensitivity to platinum-based chemotherapy. Apart from mutations in BRCA1/2 genes, the evaluation of other HRD-related alterations has been limited to date. As such, we analyzed data from mTNBC patients enrolled in the ProfiLER-01 study to determine the prevalence of alterations in homologous recombination-related (HRR) genes and their association with platinum sensitivity. METHODS: next-generation sequencing and promoter methylation of BRCA1 and RAD51C were performed on tumors from patients with mTNBC, using a panel of 19 HRR genes. Tumors were separated into three groups based on their molecular status: mutations in BRCA1/2, mutations in other HRR genes (BRCA1/2 excluded) or BRCA1/RAD51C promoter methylation and the absence of molecular alterations in HRR genes (groups A, B and C, respectively). Sensitivity to platinum-based chemotherapy was evaluated through the radiological response. RESULTS: mutations in BRCA1/2 were detected in seven (13.5%) patients, while alterations in other HRR genes or hypermethylation in BRCA1 or RAD51C were reported in 16 (30.7%) patients; furthermore, no alteration was found in the majority of patients (n = 29; 55.8%). Among 27 patients who received platinum-based chemotherapy, the disease control rate was 80%, 55% and 18% (groups A, B and C, respectively; p = 0.049). Regarding group B, patients with disease control exhibited mutations in FANCL, FANCA and the RAD51D genes or RAD51C methylation; Conclusion: mutations in HRR genes and epimutations in RAD51C were associated with disease control through platinum-based chemotherapy. As such, apart from well-characterized alterations in BRCA1/2, a more comprehensive evaluation of HRD should be considered in order to enlarge the selection of patients with mTNBC that could benefit from platinum-based chemotherapy.

RESUMO

Breast cancer with HER2-amplification accounts for 20 % of breast cancers. The management of patients has dramatically changed with the advent of anti-HER2 treatment, especially the monoclonal antibodies since 2000 in the metastatic and (neo)-adjuvant setting, leading to an improvement of patient outcomes. If therapeutic arsenal has been gradually enhanced with the targeting of HER receptors family, resistances to these treatments are observed, hence the development of new therapeutic strategies. This review provides an updated look of novel therapeutic strategies in HER2-positive breast cancer, as well as future perspectives, both in the adjuvant and metastatic setting.

RESUMO

Introduction: Bevacizumab-containing therapy is considered a standard-of-care front-line option for stage IIIB-IV ovarian cancer based on results of randomized phase 3 trials. The multicenter non-interventional ENCOURAGE prospective cohort study assessed treatment administration and outcomes in the French real-world setting. Patients and Methods: Eligible patients were aged ≥ 18 years with planned bevacizumab-containing therapy for newly diagnosed ovarian cancer. The primary objective was to assess the safety profile of front-line bevacizumab in routine clinical practice; secondary objectives were to describe patient characteristics, indications/contraindications for bevacizumab, treatment regimens and co-medications, follow-up and monitoring, progression-free survival, and treatment at recurrence. In this non-interventional study, treatment was administered as chosen by the investigator and participation in the trial had no influence on the management of the disease. Results: Of 1,290 patients screened between April 2013 and February 2015, 468 were eligible. Most patients (86%) received bevacizumab 15 mg/kg every 3 weeks or equivalent, typically with carboplatin (99%) and paclitaxel (98%). The median duration of bevacizumab was 12.2 (range 0-28, interquartile range 6.9-14.9) months; 8% of patients discontinued bevacizumab because of toxicity. The most common adverse events were hypertension (38% of patients), fatigue (35%), and bleeding (32%). There were no treatment-related deaths. Most physicians (90%) reported blood pressure measurement immediately before each bevacizumab infusion and almost all (97%) reported monitoring for proteinuria before each bevacizumab infusion. Median progression-free survival was 17.4 (95% CI, 16.4-19.1) months. The 3-year overall survival rate was 62% (95% CI, 58-67%). The most commonly administered chemotherapies at recurrence were carboplatin and pegylated liposomal doxorubicin. Discussion: Clinical outcomes and tolerability with bevacizumab in this real-life setting are consistent with randomized trial results, notwithstanding differences in the treated patient population and treatment schedule. Clinical Trial Registration:ClinicalTrials.gov, Identifier NCT01832415.
