- Abstract
We conducted a multicenter proof of concept phase II trial in patients with advanced colorectal cancer receiving FOLFIRI-cetuximab regimens to explore individual drug tailoring using pharmacogenetics and pharmacokinetics (PK) monitoring. Patients were stratified by their pharmacogenetic/phenotypic status: the irinotecan dose was adjusted according to the number of TA tandem repeats in the UGT1A1 promoter, while the 5-fluorouracil (5-FU) dose was initially adjusted according to dihydropyrimidine dehydrogenase (DPD) activity at initial screening (5-FU
ODPM Tox ) followed by PK-guided dose optimization (5-FUODPM Protocol ). An advanced cetuximab PK/pharmacodynamics (PD) study was performed but dosage remained unchanged. Eighty-five patients receiving second-line chemotherapy were enrolled. Mean irinotecan doses at 3 months were 247 ± 50, 210 ± 53 and 140 ± 21 mg/m2 for those with 6/6 (33), 6/7 (26), and 7/7 (7) TATA repeats in the UGT1A1 promoter region, respectively. The 5-FU dose was initially reduced in four patients with DPD deficiency, but mean 5-FU dose at 3 months was 2,412 ± 364 mg/m2 (1,615-3,170 mg/m2 ). Grade 4 toxicities were not encountered and grade 4 neutropenia occurred in 6.8%, 5.9%, and 0% of patients with 6/6, 6/7, and 7/7 UGT1A1 genotypes. The objective response rate was 25.8% among the 85 patients, 57.3% in patients with tumors wild type (WT) for KRAS, and 25% in those whose tumor harbored a mutant-KRAS. Secondary resection of hepatic metastases was performed in 31.7% of patients. Median progression-free survival (PFS) for all 85 patients was 181 days and 200, 132, and 121 days for patients with 6/6, 6/7, and 7/7 UGT1A1 genotypes, respectively; these differences were not statistically different. In parallel, a strong relationship was shown between cetuximab AUC and regimen efficacy. We conclude that personalized drug tailoring when administering in FOLFIRI + cetuximab allows for safe and efficient individual dose intensification., (Copyright © 2017 Elsevier Inc.

- Abstract
Background: The current retrospective study was intended to obtain up-to-date and comprehensive data on surgical practice for breast cancer throughout France, including neoadjuvant chemotherapy (NAC) and the more recent surgical techniques of oncoplastic surgery (OPS)., Methods: In June 2011, e-mail surveys were sent to 33 nationally renowned breast cancer surgeons from French public or private hospitals. The questionnaire focused on all the new cases of breast cancer treated in 2010. It included questions regarding surgical practices, with special emphases on NAC and OPS and other surgical characteristics., Results: The overall response rate for the survey was 72.7 %. The total number of breast cancer cases from the survey was 13,762, which constitutes 26.2 % of the total incidence in 2010. Breast-conserving surgery (BCS) was performed for 71.0 % of the patients, and the results were similar throughout the types of practices. Of these patients, 13.9 % received OPS, either upfront or after NAC. Mastectomy was performed for 29.0 % of the patients, which is consistent with French official numbers. Among all patients, 16.3 % underwent surgery after NAC., Conclusion: To the authors' knowledge, there are no publications of national figures on NAC or OPS rates to date. They are convinced that this study offers real-life surgical care information on a large population and covers France's breast cancer surgical landscape. Mastectomy rates in France remain stable and consistent with those in other European countries. However, additional large-scale retrospective studies are required to confirm these figures and further explore NAC and OPS rates as well as surgical practice characteristics.

- Abstract
This article, devoted specifically to gynaecological cancers and their impact on the sexual and marital lives, is a collaboration between the psychologists and onco-gynaecologist within a cancer center. In oncology, gynaecological cancers' treatments involve at the same time anatomical, physiological and functional modifications impacting, in a major way, on the sexual life of women. All the phases of the sexual answer can be touched. Beyond the physical and aesthetic consequences of the treatments, the sexual dysfunctions are generally caused by the deep psychological upheaval induced by the disease affecting a strongly invested female body. Female cancer is also a true test for the couple challenged in its emotional, functional and sexual cohesion: emotional distress, attachment link dysfunction, change of role within the couple, disordered state of communication. The couple cannot survive and find a harmonious intimate life without communication about sexual health between the medical team, the patient and her partner. All doctors and nurses must be able to initiate the subject throughout the course of care by respecting four prerequisites: to be aware of the importance to approach this subject, to create a climate of trust, to dare the questions and to respect the rhythm of the patient and her partner., (Copyright © 2015 Société Française du Cancer.

- Abstract
Advances in medical imaging have greatly enhanced the speciality of radiation oncology by allowing more healthy tissue to be speared for better tumour coverage. Positron emission tomography (PET) with the glucose analogue [18F]-fluoro-2-deoxy-D-glucose (FDG) is a functional imaging method that has become widely used in oncology over the last decade. It has been rapidly incorporated in the staging and treatment planing of many patients with cancer in several anatomic sites such as non-small cell lung carcinomas. However, the initial data were controversial by the use of non dedicated PET units, the lack of patient immobilisation for radiation therapy, or the lack of image registration for fusion PET images with computed tomography (CT). The increased number of combined PET/CT units installed and the development of new isotopes that allow advances in biological and molecular tumour and healthy tissue imaging should lead to enhanced target definition for highly conformal radiation therapy. Such developments might also allow tumour viability or healthy tissue function to be imaged, which could be used during treatment as early indicators of tumour response or healthy tissue injury, possibly leading to a change in treatment strategy based on functional and biological imaging. The contribution of PET imaging advances using FDG or new tracers for treatment planing in the new era of image guided radiation therapy will be discussed in this review.

- Abstract
One of the most recent advances in the management of Her-2/neu positive breast cancer is the validation of a targeted therapy from bench to the clinic, particularly towards the adjuvant setting. The recommended dose of trastuzumab (Herceptin), a humanized monoclonal antibody targeting the HER-2 antigen, has been determined in phase I studies. In the metastatic patients two randomised trials have demonstrated its efficacy when associated to taxanes. In less than 10 years, trastuzumab became the standard of care in the adjuvant treatment of HER-2/neu positive breast cancer. In this setting, two combinations regimen with chemotherapy (concomitant or sequential) have been recently published. The concomitant schedule has been used in three studies (North American Group, BCIRG, FinHer), whereas in the Hera trial trastuzumab was started after the end of neo-adjuvant and adjuvant chemotherapy. In this article, the advantages and uncertainties on efficacy and toxicities of the trastuzumab administration modalities, associated or not to chemotherapy and radiation therapy, are discussed.
