La place de la chimiothérapie dans le traitement du cancer broncho pulmonaire

Single agent chemotherapy of advanced lung cancer is still unsatisfactory. The most encouraging results have been obtained with high dose intermittent treatment with cyclophosphamide, methotrexate or adriamycin. Combination chemotherapy is probably more efficacious than single agent chemotherapy, especially in oat cell carcinoma. The best treatment schedules give a response rate of approximately 80%. The value of adjuvant chemotherapy is not yet established, but new controlled clinical trials are indicated considering the poor results achieved by surgery and radiotherapy.

Les facteurs de transcription du groupe PEA3: Régulateurs transcriptionnels dans le processus de cancérisation

Erm, Er81, and Pea3 are the three members of the PEA3 group which belong to the Ets transcription factors family. These proteins regulate transcription of multiple target genes, such as those encoding several matrix metalloproteinases (MMP), which are enzymes degrading the extracellular matrix during cancer metastasis. In fact, PEA3-group genes are often overexpressed in different types of human cancers that also over-express these MMP and display a disseminating phenotype. In experimental models, regulation of PEA3 group member expression has been shown to influence the metastatic process, thus suggesting that these factors play a key role in metastasis. © John Libbey Eurotext.
