The emergence of oral cancer treatment in oncology has shifted patient follow-up from the hospital to the home. This trend has resulted in an increase in phone and e-mail interactions initiated by patients, but also by pharmacists, by liberal nurses, by general practitioners, and an increase in calls to the emergency response services (SAMU) both for real or perceived emergencies. This increased volume of patient and pharmacist communication has caused significant disruption in the daily activity of affected oncology departments and in particular of the secretariats. The procedures for formulating and securing appropriate responses within a short time frame are generally not established, and as a result, there is a risk that decisions made could be inappropriate for the patient's situation, especially in the case of complications.. Tracking responses to phone calls is necessary and answers should be noted in the medical file, including side effects, in particular the serious AEs for a good quality of care. This guideline describes best practices for oncologists who manage "incoming" calls from patients or professionals involved in the care pathway., (Copyright © 2019 Société Française du Cancer.

Positron Emission Tomography (PET) is a functional nuclear medicine imaging technique which clinical value in oncology has been demonstrated. PET indications are constantly evolving, thanks to the contribution of research. The use of PET in oncology has been the subject of recommendations according to the Standard-Options-Recommendations methodology from the Fédération Nationale des Centres de Lutte Contre le Cancer in 2002, updated in 2003. However, many scientific works have been published since 2003 and new tracers have also obtained a marketing authorization in France. The objective of this work was therefore to update the recommendations established in 2003. In this context, in collaboration with the Société française de médecine nucléaire, a working group was set up for the development of good clinical practice recommendations under the HAS-INCA methodological label. The present document is issued from a comprehensive review of the literature and rigorous appraisal by a panel of national experts, organ specialists, clinical oncologists, surgeons, and imaging specialists. It is intended to be used as a guide to decision-making for those oncology teams that are able to manage patients in various situations in which the AMM label is not sufficiently precise., (Copyright © 2019 Société Française du Cancer.

Despite being 60-years old now, 5-FU remains the backbone of numerous regimen to treat a variety of solid tumors such as breast, head-and-neck and digestive cancers either in neo-adjuvant, adjuvant or metastatic settings. Standard 5-FU usually claims 15-40% of severe toxicities and up to 1% of toxic-death. Numerous studies show a stiff relationship between 5-FU exposure and toxicity or efficacy. In addition, 5-FU pharmacokinetics is highly variable between patients. Indeed, 80% of the 5-FU dose is catabolized in the liver by dihydropyrimidine dehydrogenase (DPD) into inactive compounds. It is now well established that DPD deficiency could lead to severe toxicities and, thus, require dose reduction in deficient patients. However, despite dosage adaptation based on DPD status, some patients may still experience under- or over-exposure, leading to inefficacy or major toxicity. The "Suivi thérapeutique pharmacologique et personnalisation des traitements" (STP-PT) group of the "Société française de pharmacologie et de thérapeutique" (SFPT) and the "Groupe de pharmacologie clinique oncologique" (GPCO)-Unicancer, based on the latest and most up-to-date literature data, recommend the implementation of 5-FU Therapeutic Drug Monitoring in order to ensure an adequate 5-FU exposure., (Copyright © 2018 Société Française du Cancer.

Fluoropyrimidines (FU) are still the most prescribed anticancer drugs for the treatment of solid cancers. However, fluoropyrimidines cause severe toxicities in 10 to 40% of patients and toxic deaths in 0.2 to 0.8% of patients, resulting in a real public health problem. The main origin of FU-related toxicities is a deficiency of dihydropyrimidine dehydrogenase (DPD), the rate-limiting enzyme of 5-FU catabolism. DPD deficiency may be identified through pharmacogenetics testing including phenotyping (direct or indirect measurement of enzyme activity) or genotyping (detection of inactivating polymorphisms on the DPYD gene). Approximately 3 to 15% of patients exhibit a partial deficiency and 0.1 to 0.5% a complete DPD deficiency. Currently, there is no regulatory obligation for DPD deficiency screening in patients scheduled to receive a fluoropyrimidine-based chemotherapy. Based on the levels of evidence from the literature data and considering current French practices, the Group of Clinical Pharmacology in Oncology (GPCO)-UNICANCER and the French Network of Pharmacogenetics (RNPGx) recommend the following: (1) to screen DPD deficiency before initiating any chemotherapy containing 5-FU or capecitabine; (2) to perform DPD phenotyping by measuring plasma uracil (U) concentrations (possibly associated with dihydrouracil/U ratio), and DPYD genotyping (variants *2A, *13, p.D949V, HapB3); (3) to reduce the initial FU dose (first cycle) according to DPD status, if needed, and further, to consider increasing the dose at subsequent cycles according to treatment tolerance. In France, 17 public laboratories currently undertake routine screening of DPD deficiency., (Copyright © 2018 Société Française du Cancer. Published by Elsevier Masson SAS. All rights reserved.)

In order to help the clinician, mathematical models including several clinical and pathological variables are proposed in the literature with the aim to predict the occurrence of an event of interest. Nomograms allow individual prognosis for each patient. When they are developed, validated and correctly used, nomograms can provide important information for patients' care. But, despite the strong interest in nomograms in oncology, statistical methodologies used remain unknown from the medical community. This paper presents the major steps in the development, the validation and the clinical use of nomograms. Examples are given to illustrate these different points and the limits of this methodology. Finally, guidelines on the use of nomograms are proposed for clinicians., (Copyright © 2017 Société Française du Cancer. Published by Elsevier Masson SAS. All rights reserved.)

Cure rates for most childhood cancers and adolescents have made remarkable progress over the last thirty to forty years. The development of secondary malignancies has become an important question for these patients. The frequency is low, but the risk is significantly higher (between 3 and 10 times) and it is the leading cause of long-term mortality off relapse. In this literature review, we discuss the epidemiological aspect and the risk factors contributing to this increased risk, and conclude with a summary of current recommendations for screening and surveillance. We also discuss briefly the constitutional predisposing genetic contributions to other cancers., (Copyright © 2015 Société Française du Cancer. Published by Elsevier Masson SAS. All rights reserved.)
