Oncogénétique et psycho-oncologie, une collaboration recommandée...

Résumé: La possibilité depuis 1994, de connaître la probabilité individuelle de développer certains cancers a permis de proposer de nouvelles modalités de prévention, de traitements et contribué au développement actuel de loncogénétique. Une meilleure connaissance des répercussions psychologiques tant pour les patients que pour les apparentés est désormais possible et limplication des psycho-oncologues dans ce cadre de la réalisation des tests prédictifs, recommandée. La mission de «messager» qui incombe au «cas-index» doit faire lobjet dune attention particulière. La complexité de linformation et la dimension paradoxale que peut avoir parfois la communication à propos des choix, rend difficile lévaluation de la qualité du consentement. La situation particulièrement délicate dune aide à la décision à légard de la chirurgie prophylactique, exige une collaboration étroite des généticiens et des psycho-oncologues.Les soins de support en oncologie     

The role of papillomaviruses in human cancers

This review comprehensively evaluates the influence of gene-gene, gene-environment and multiple interactions on the risk of colorectal cancer (CRC). Methods of studying these interactions and their limitations have been discussed herein. There is a need to develop biomarkers of exposure and of risk that are sensitive, specific, present in the pathway of the disease, and that have been clinically tested for routine use. The influence of inherited variation (polymorphism) in several genes has been discussed in this review; however, due to study limitations and confounders, it is difficult to conclude which ones are associated with the highest risk (either individually or in combination with environmental factors) to CRC. The majority of the sporadic cancer is believed to be due to modification of mutation risk by other genetic and/or environmental factors. Micronutrient deficiency may explain the association between low consumption of fruit/vegetables and CRC in human studies. Mitochondrial modulation by dietary factors influences the balance between cell renewal and death critical in colon mucosal homeostasis. Both genetic and epigenetic interactions are intricately dependent on each other, and collectively influence the process of colorectal tumorigenesis. The genetic and environmental interactions present a good prospect and a challenge for prevention strategies for CRC because they support the view that this highly prevalent cancer is preventable.     

Antifungal combination therapy in localized candidosis

A mouse model of localized candidosis in air-filled subcutaneous cysts imitating thrush has been developed. We have now tested various antifungal combinations in this animal model. Flucytosine (5-FC) + amphotericin B (Amph B) showed the highest efficacy, a clear additive or even synergistic effect was seen. The combination of 5-FC + imidazole or triazole derivative was less efficacious, an additive effect was rare. The combination of 5-FC + Amph B was also tested against Candida albicans strains showing various degrees of 5-FC-resistance. A significant reduction in 5-FC-resistant mutants was seen after the treatment with the combination.     

Les génériques en cancérologie: à molécule identique, médicaments identiques? Les biosimilaires, des super-génériques?

Résumé: Les biosimilaires vont bientôt voir leur apparition en Europe. Comment un laboratoire peut-il aborder le développement de son dossier dAMM? Quelles sont les bases légales et les recommandations officielles? Comment la similarité et/ou le caractère générique peuvent-ils être démontrés? Les règles sont-elles identiques à celles des produits chimiques conventionnels pour lesquels, notamment en cancérologie, il existe des médicaments génériques? Comment faire pour que la sécurité et lefficacité des médicaments biosimilaires soient assurées pour les patients?     

Cancer immunotherapy

Unprecedented progress has seen made in the last decade in the field of cancer immunotherapy. The recent approval of nivolumab （Opdivo）, the first anti-programmed cell death-1 （PD-1） antibody, for metastatic melanoma in Japan, marked a milestone in the rapidly advancing field of cancer immunotherapy. Nivolumab together with ipilimumab （Yervoy）, the anti-cytotoxic T-lymphocyte-associated antigen-4 （CTLA-4） antibody, are the first 2 drugs in the class of ＂immune checkpoint inhibitors＂ that have delivered impressive responses in patients with metastatic melanoma and renal cell cancer （RCC） as well as a variety of solid tumors.     

Effect of tumor therapeutic irradiation on the mechanical properties of teeth tissue

Tumor irradiation of the head-neck area is accompanied by the development of a so-called radiation caries in the treated patients. In spite of conservative therapeutic measures, the process results in tooth destruction. The present study investigated the effects of irradiation on the demineralization and remineralization of the dental tissue. For this purpose, retained third molars were prepared and assigned either to a test group, which was exposed to fractional irradiation up to 60 Gy, or to a non-irradiated control group. Irradiated and non-irradiated teeth were then demineralized using acidic hydroxyl-cellulose gel; afterwards the teeth were remineralized using either Bifluorid12 or elmex gelee. The nanoindentation technique was used to measure the mechanical properties, hardness and elasticity, of the teeth in each of the conditions. The values were compared to the non-irradiated control group. Irradiation decreased dramatically the mechanical parameters of enamel and dentine. In nonirradiated teeth, demineralization had nearly the same effects of irradiation on the mechanical properties. In irradiated teeth, the effects of demineralization were negligible in comparison to non-irradiated teeth. Remineralization with Bifluorid12 or elmex gelee led to a partial improvement of the mechanical properties of the teeth. The enamel was more positively affected by remineralization than the dentine.     

Consultation multidisciplinaire pour les patients atteints d’une pathologie tumorale (carcinome infiltrant ou lésion précancéreuse) liée à HPV : la consultation multidisciplinaire papillomavirus

Given the recent increase in the number of human papillomavirus (HPV)-induced cancers in other locations than gynaecological, the number of patients with two cancers at distinct sites, and because of the lack of exhaustive data, we decided to create a multidisciplinary network around an HPV consultation at the Georges-Pompidou European Hospital (HEGP). This network aims to set up the best tools for detecting HPV-associated “multisite” precancerous lesions in order to determine the possible impact of dedicated care for this at-risk population. This monthly consultation was created at the HEGP in June 2014. It is currently organized around five consultations: gynaecological, ENT, urological, digestive and immunological. Every patient who has been diagnosed with HPV-related cancer and whose care is provided at the HEGP is offered this particular follow-up: systematically, once the initial lesion has been treated, the patient is convened annually for a day during which it benefits from the consultations mentioned above. A consultation with a psychologist is systematically proposed. Local samples are taken at each site: a cytological examination, the analysis of known predictive and prognostic virological markers are carried out. This study fits more broadly in a theme of clinical and fundamental research around cancers related to HPV.     

Differentiation state and invasiveness of human breast cancer cell lines

Summary Eighteen breast cancer cell lines were examined for expression of markers of epithelial and fibroblastic differentiation: E-cadherin, desmoplakins, ZO-1, vimentin, keratin and ₁ and ₄ integrins. The cell lines were distributed along a spectrum of differentiation from epithelial to fibroblastic phenotypes. The most well-differentiated, epithelioid cell lines contained proteins characteristic of desmosomal, adherens and tight junctions, were adherent to one another on plastic and in the basement membrane matrix Matrigel and were keratin-positive and vimentin-negative. These cell lines were all weakly invasive in anin vitro chemoinvasion assay. The most poorly-differentiated, fibroblastic cell lines were E-cadherin-, desmoplakin- and ZO-1-negative and formed branching structures in Matrigel. They were vimentin-positive, contained only low levels of keratins and were highly invasive in thein vitro chemoinvasion assay. Of all of the markers analyzed, vimentin expression correlated best within vitro invasive ability and fibroblastic differentiation. In a cell line with unstable expression of vimentin, T47D_CO, the cells that were invasive were of the fibroblastic type. The differentiation markers described here may be useful for analysis of clinical specimens and could potentially provide a more precise measure of differentiation grade yielding more power for predicting prognosis.
