J Thorac Oncol page 7 Author manuscript, increases available in PMC 13th June 2012. limited stage SCLC will be presented at this conference survival associated with low levels of ERCC1 better when treated with platinum-based chemo-radiotherapy. Treated in a small retrospective study of 61 patients with advanced NSCLC with cisplatin and gemcitabine, low RRM1 levels were associated with a trend for a better median survival time compared to high levels of mRNA RRMI. Similar results were observed in the group with concomitant low levels of expression of ERCC1 and RRM1.
Although XAV-939 the results are intriguing, no definitive conclusions from this small retrospective study can be drawn. Until recently, technical Restrict prevented Website will immunohistochemical analysis of proteins Embedded in paraffin tissue samples RRM1. From the group of patients who do not U were re-adjuvant chemotherapy in the study IALT, was the improved survival for those with ERCC1-positive tumors than those with ERCC1-negative tumors. In a retrospective study of patients with resected stage I NSCLC, median survival time free of disease was significantly better in the high RRM1 protein expression than in those with low RRM1 expression. It is conceivable that efficient DNA repair could slow or prevent the progression of molecular events, even in established tumors and tr gt Order to improve the survival period in patients with resected NSCLC.
In fact, the predicted combination of RRM1 and ERCC1 survive better than high high high expression of the protein is only in this study. Those U low ERCC1 Re: In a prospective study presented at the conference, investigators HL Moffitt Cancer Center, 53 patients with advanced NSCLC to therapy based on platinum or nonplatinum assigned based on tumor ERCC1 expression and platinum-containing doublet, those who High ERCC1 had back u with a nonplatinum doublet. The choice of the agent in the second group platinumcontaining doublet was RRM1 expression on the tumor. Patients with low RRM1 expression was again U carboplatin and gemcitabine, and those that high expression of RRM1 have again U docetaxel and carboplatin.
In Similar way, patients have associated with nonplatinum doublet again U either gemcitabine and docetaxel or docetaxel and vinorelbine. The overall objective of progression-free survival 1 year free was 18% and overall survival was 62% a year. The median overall survival time was 13.4 months, which reported better than the traditional 9 to 10 months h Ufigsten therapy with platinum-based doublet was. The story unfolds, the variation in rates of key enzymes involved in DNA repair pathway in established tumors has important implications for cancer therapy.
