Vinorelbine, ifosfamide and cisplatin as first-line treatment in patients with inoperable non-small cell lung cancer.

To assess, in a multicenter setting, the effectiveness of a combination of vinorelbine, ifosfamide and cisplatin in the treatment of non-small cell lung cancer, 123 patients (males=116) with a mean age of 60 years (range 27-75) with stage IIIb/IV non-small cell lung cancer (NSCLC) and performance status

Prognostic significance of c-erbB-2/neu amplification and epidermal growth factor receptor (EGFR) in primary breast cancer and their relation to estradiol receptor (ER) status.

The aim of this study is to evaluate the prognostic significance of c-erbB-2/neu amplification and epidermal growth factor receptor (EGFR) expression in primary breast cancer (BC) and their prognostic implications when combined with estradiol receptor (ER) status. In this work, 825 BCs were studied. Neu amplification was evaluated by dot-blot and EGFR expression was evaluated by ligand binding assay using I125-EGF. Neu, EGFR, estradiol and progesterone receptors (ER and PR) had a marked influence on disease free survival (DFS) in univariate analysis. In node-negative (NO) cases only neu was associated with short DFS (p = 0.005). However, in node-positive (N+) cases both EGFR (p = 0.005) and neu (p = 0.002) influenced DFS. None of the biological markers were significant predictors for overall survival (OS) in NO/BC. On the contrary, in N+/BC, EGFR + (p = 0.003) was associated with short OS. The EGFR + /neu/phenotype represented a sub-group with an even worse prognosis with respect to DFS (p = 0.0034) as well as EGFR + /ER-tumors (p = 0.005). Moreover, neu + /ER-patients also had a high probability of relapse (p = 0.0000) and death (p = 0.006). C-erbB-2/neu, EGFR, histological grade, pN, pT and ER were subjected to a Cox multivariate regression analysis: neu was the most important parameter in predicting recurrence, and EGFR was a significant predictor for OS.

Pharmacokinetics of CuDIPS in mice.

Pharmacokinetic evaluation of Cu(II)2(3,5-diisopropylsalicylate)4(H2O)2 (CuDIPS), a copper complex with anticancer activity in mice, showed rapid absorption into the circulation after subcutaneous (SC) injection of a 0.50mumol, 0.75 mumol or 1.0 mumol dose. A direct relationship was observed between peak plasma copper concentration (one or two hours) and dose. Rate of plasma release also appeared to be dose related. The lowest dose of CuDIPS had no effect on plasma zinc levels; higher doses produced significant increases, but only at one hour. Rapid absorption into the blood (apparent peak in concentration, Tmax, at 0.5 hours) was also found in studies to determine distribution of 67Cu after SC injection of 67Cu and 14C double-labeled CuDIPS (50 mumol/kg body weight). Distribution to other tissues and organs occurred less rapidly with apparent peak 67Cu concentrations at three hours after administration in femur (bone marrow) and intestine, and at six hours in spleen and thymus.
