RESUMO
The National Cancer Institute Common Terminology Criteria for Adverse Events classification is the standard classification used by the physicians in oncology for reporting adverse events. This classification has evolved over the last years according to the emergence of new therapies. Reporting symptoms, quality of life (QoL) and toxicities via patient-reported outcomes (PROs) in clinical practice is not yet a standard of care, nevertheless many studies have been conducted recently to assess feasibility and impact of routine monitoring of PROs, which should enable for better management of toxicities and earlier detection of disease progression in a more patient-centered health care delivery system. The aim of this article was to discuss the advantages and limitations of both approaches, clinicians-reported outcomes and PROs. Growing evidence supports that the routine collection of PROs leads to improvement of QoL and overall survival of cancer patients.

An initial validation of a standardized pharmaceutical counselling guide was carried out in a previous study to improve medication adherence in patients treated for multiple myeloma with oral anticancer therapies. The main objective of this work was the final validation of this guide with 10 naive patients. The main secondary objectives were to assess for the patient the evolution of knowledge about the treatment, understanding of the purpose of the pharmaceutical counselling, adherence to the tools. Each patient completed a self-administered questionnaire: before and after the first pharmaceutical counselling. The primary endpoint was the average success rate per question after the pharmaceutical counselling (a value of ≥ 90% validated knowledge acquisition). Secondary judgement criteria were: change in average success rates per patient and question, rate of reformulation of the objective of the pharmaceutical counselling, response rate to presentation questions, readability and understanding. No average success rate per question after the pharmaceutical counselling was statistically less than 90%. The average success rates per patient before and after the pharmaceutical counselling were 78.9±13.7% vs 96.1±3.9% (P=0.01). The average success rates per question were different for 4 questions. All patients were able to reformulate the objective of the pharmaceutical counselling and validated the presentation, readability and understanding of the documents. This study led to the final validation of the pharmaceutical counselling guide.

The safety of the community treatment with oral anticancer therapies is a strong theme of the cancer plan 2014-2019. The objective of this study was to develop a Pharmaceutical Counseling Guide to improve medication adherence in patients treated for multiple myeloma with oral anticancer therapies. A multidisciplinary professional working group selected a list of relevant medication adherence-related items that served as the framework for the design of the pharmaceutical counseling support materials in patient-accessible language. The readability, understanding and memorization of the information were validated in ten patients treated for myeloma. Twelve items were selected for treatment information (5 items), treatment planning (5 items), and adverse drug effects (2 items). A pharmacist guide, a patient guide, a medication schedule, and three self-questionnaires to evaluate medication knowledge and understanding of patients were developed. The patient test resulted in changes in these documents. This study carried out the initial validation of documents to standardize the pharmaceutical counseling for patients treated for myeloma so that it can be reproduced from one patient to another regardless of the pharmacist, by standardizing the information issued. This study needs to be completed by a final validation in myeloma patients, free from oral anticancer therapies.

INTRODUCTION: Chemotherapy induced toxicities can generate changes in prescribing and relative dose intensity which have an impact on therapeutic efficacy. METHOD: This is a prospective observational study performed in hepato-gastroenterology department for 6 months. All patients treated for colorectal cancer and beginning a protocol with at least one parenteral drug have been included. RESULTS: Among the 48 patients enrolled, 85.4% of them had at least one prescription change, which concerned 30.3% of 238 cycles. Of the 766 analyzed prescription lines, 16.6% of them were postponed and/or 6.7% had modified dosage and/or 5.6% were stopped prematurely. Grades 2 to 4 adverse reactions were responsible for at least one change prescribing to 64.6% of patients and 17.6% of cycles. Toxicity induced prescription changes were mainly due to clinical toxicities (79.3%). The rate of patients with a relative dose intensity greater than 70% was 92.9% in adjuvant state, 66.7% and 62.5% in metastatic state first line and second and subsequent line. CONCLUSION: High-grade clinical toxicities are the main chemotherapy prescription change pattern in colorectal cancer. Knowledge of toxicities before the patient's arrival is expected to target patients for which the drug preparation can be anticipated and for which a cycle postponement, dose adjustment or discontinuation is necessary.

We applied a novel profiling approach using receptor binding domain (RBD) ligands to cell surface domains of a panel of nutrient transporters to characterize the impact of a number of tyrosine kinase inhibitor anticancer drugs on human stem cell-derived cardiomyocytes. High-content screening and flow cytometry analysis showed diagnostic changes in nutrient transporter expression correlating with glycolysis and oxidative phosphorylation-based cell metabolism in glucose and galactose media. Cluster analysis of RBD binding signatures of drug-treated cells cultured in glucose medium showed good correlation with sensitization of mitochondrial toxicity in cells undergoing oxidative phosphorylation in galactose medium. These data demonstrate the potential for RBD ligands as profiling tools to improve the clinical predictivity of in vitro cell assays for drug toxicity.

The (pro)renin receptor [(P)RR] is a 35-kDa transmembrane protein that plays a pivotal role in angiotensin tissue generation and in nonproteolytic prorenin activation. We detected a soluble form of (P)RR [s(P)RR; 28 kDa] in the conditioned medium of cultured cells. The aims of our study were to identify the protease responsible for the generation of s(P)RR, the site of shedding, and to establish the existence of circulating s(P)RR in plasma. We identified furin as the protease responsible for the shedding of endogenous (P)RR based on the following: LoVo colon carcinoma cells devoid of active furin synthesize full-length (P)RR but do not secrete s(P)RR; transfection of Chinese hamster ovary cells with a plasmid coding for alpha1-antitrypsin Portland variant, an inhibitor of furin, completely inhibited the generation of s(P)RR, whereas addition of GM6001, an inhibitor of metalloproteases or of tumor necrosis factor-alpha protease inhibitor-1, an inhibitor of ADAM17, in the culture medium has no effect; when the cDNA coding for (P)RR was translated in vitro and incubated with recombinant furin or ADAM17, only furin was able to generate the 28 kDa-s(P)RR, and mutagenesis in the potential furin cleavage R275A/KT/R278A site abolished s(P)RR generation. Immunofluorescence study in glomerular epithelial cells showed that (P)RR was cleaved in the trans-Golgi, and coprecipitation experiments with renin showed that s(P)RR was present in plasma. In conclusion, our results show that s(P)RR is generated intracellularly by furin cleavage, and that s(P)RR detected in plasma is able to bind renin.
