[uPA/PAI-1, Oncotype DX™, MammaPrint(®). Prognosis and predictive values for clinical utility in breast cancer management]. / uPA/PAI-1, Oncotype DX™, Mammaprint(®). Valeurs pronostique et prédictive pour une utilité clinique dans la prise en charge du cancer du sein.

CONTEXT AND AIMS: Breast cancer prognosis and predictive biomarkers development would allow sparing some patients from chemotherapy or identifying patients for whom chemotherapy would be indicated. In this context, in 2009, the French National Cancer Institute, a National Health and Science Agency dedicated to cancer, in collaboration with the French society of senology and breast pathology (SFSPM) published a report on the assessment of the prognostic and the predictive clinical validity of tissular biomarkers, uPA/PAI-1, Oncotype DX™ and MammaPrint(®), in breast cancer management. They concluded that only the uPA/PAI-1 prognosis value reached the highest level of evidence (LOE I according to Hayes 1998 classification). In 2012, it was decided to update this report since new data have emerged and because information disparities among clinicians have been identified. This article aims to present the main conclusions together with the levels of evidence associated with those conclusions. METHODS: The updating process was based on literature published since 2009 appraisal and on multidisciplinary and independent experts' opinion. The levels of evidence (LOE) used are those of the classification defined by Simon in 2009 (updated Hayes 1998 classification): LOE IA and LOE IB: high level of evidence; LOE IIB and LOE IIC: intermediate level of evidence; LOE IIIC and LOE IV-VD: low level of evidence. CONCLUSIONS: Among patients without lymph-node involvement, uPA/PAI-1, invasion process biomarkers, reach the highest level of evidence for 10 years recurrence free survival prognosis (LOE IA according to Simon). The predictive value to anthracyclins chemotherapy remains to be confirmed. Oncotype DX™ and MammaPrint(®) prognosis and predictive value do not reach the LOE I level. This updating' process confirms the 2009 levels of evidence for all the three biomarkers prognosis value. Besides, concerning Oncotype DX™ and MammaPrint(®), new data do not allow to conclude neither to their complementary clinical information to other clinicopathological existing biomarkers nor to a favorable cost-efficiency ratio in therapeutic decision making and this because of the methodological weakness and uncertainty that are identified in the selected studies. Practically, beyond the prognosis and predictive biomarkers validity, the clinical utility of a new biomarker for chemotherapy indication depends on its clinical added information with regard to validated biomarkers (HR, HER2 and Ki67) and to clinicopathological parameters. Since they are the sole validated biomarkers of the invasion process, uPA/PAI-1 could complete clinical information of other clinicopathological factors and consequently could confer an added clinical value. However, data concerning the impact of this information on chemotherapy clinical indication are lacking.

[Loco-regional treatments of the metastatic sites for patients with pauci-metastatic cutaneous melanoma (without brain metastasis): French national guidelines]. / Traitements locorégionaux des sites métastatiques chez des patients atteints d'un mélanome pauci-métastatique (hors métastase cérébrale) : recommandations nationales françaises.

INTRODUCTION: The last years are marked by the emergence of new molecules for the treatment of metastatic cutaneous melanoma with a significant benefit on the survival. Besides, some techniques are in development for the loco-regional treatment of the metastatic sites, bringing new therapeutic perspectives. However, their respective use and place in the therapeutic strategy are debated by healthcare professionals. OBJECTIVE: The French National Cancer Institute leads a national clinical practice guidelines project since 2008. It realized a review of these modalities of treatment and developed recommendations. METHODS: The clinical practice guidelines development process is based on systematic literature review and critical appraisal by a multidisciplinary expert workgroup. The recommendations are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines are reviewed by independent practitioners in cancer care delivery. RESULTS: This article presents recommendations for loco-regional treatments of the pulmonary, bone, cutaneous, hepatic and digestive metastatic sites for patients with pauci-metastatic cutaneous melanoma.

Clinical practice guidelines for the management of patients with endometrial cancer in France: recommendations of the Institut National du Cancer and the Société Française d'Oncologie Gynécologique.

INTRODUCTION: Endometrial cancer is the most common gynecological malignancy in France, with more than 6500 new cases in 2010. The French National Cancer Institute has been leading a clinical practice guidelines (CPG) project since 2008. This project involves the development and updating of evidence-based CPG in oncology. OBJECTIVE: To develop CPG for diagnosis, treatment, and follow-up for patients with endometrial cancer. METHODS: The guideline development process is based on systematic literature review and critical appraisal by experts, with feedback from specialists in cancer care delivery. The recommendations are thus based on the best available evidence and expert agreement. RESULTS: Main recommendations include a routine pelvic magnetic resonance imaging in association with magnetic resonance imaging exploration of the para-aortic lymph nodes for locoregional staging, surgical treatment based on total hysterectomy with bilateral salpingo-oophorectomy with or without lymphadenectomy, and clinical examination for the follow-up. The initial laparoscopic surgical approach is recommended for stage I tumors. Lymphadenectomy and postoperative external radiotherapy are recommended for patients with high risk of recurrence but are restricted for patients with low or intermediate risk. If brachytherapy is indicated, it should be given at a high-dose rate rather than a low-dose rate. Routine imaging, biologic tests, and vaginal smears are not indicated for follow-up.

CoCanCPG. Coordination of cancer clinical practice in Europe.

All European countries are facing common challenges for delivering appropriate, evidence-based care to patients with cancer. Despite tangible improvements in diagnosis and treatment, marked differences in cancer survival exist throughout Europe. The reliable translation of new research evidence into consistent patient-oriented strategies is a key endeavour to overcome inequalities in healthcare. Clinical-practice guidelines are important tools for improving quality of care by informing professionals and patients about the most appropriate clinical practice. Guideline programmes in different countries use similar strategies to achieve similar goals. This results in unnecessary duplication of effort and inefficient use of resources. While different initiatives at the international level have attempted to improve the quality of guidelines, less investment has been made to overcome existing fragmentation and duplication of effort in cancer guideline development and research. To provide added value to existing initiatives and foster equitable access to evidence-based cancer care in Europe, CoCanCPG will establish cooperation between cancer guideline programmes. CoCanCPG is an ERA-Net coordinated by the French National Cancer Institute with 17 partners from 11 countries. The CoCanCPG partners will achieve their goal through an ambitious, stepwise approach with a long-term perspective, involving: 1. implementing a common framework for sharing knowledge and skills; 2. developing shared activities for guideline development; 3. assembling a critical mass for pertinent research into guideline methods; 4. implementing an appropriate framework for cooperation. Successful development of joint activities involves learning how to adopt common quality standards and how to share responsibilities, while taking into account the cultural and organisational diversity of the participating organisations. Languages barriers and different organisational settings add a level of complexity to setting up transnational collaboration. Through its activities, CoCanCPG will make an important contribution towards better access to evidence-based cancer practices and thus contribute to reducing inequalities and improving care for patients with cancer across Europe.
