Abstract

A phase II study of a triplet chemotherapy with the administration sequence of gemcitabine (GEM), docetaxel (DCT) and cisplatin (CDDP) (OLCSG9908) was previously conducted in patients with advanced non-small cell lung cancer (NSCLC). The objective response rate was 34% and the median survival time (MST) and 1-year survival rate were 11.7 months and 49%, respectively. In an in vitro study of different sequence exposures to GEM and DCT, it was reported that the synergistic effect was more prominent using the administration sequence of DCT followed by GEM compared with the reverse sequence. In order to estimate the effects of the administration sequence, a phase II study of the same triplet chemotherapy was conducted with the administration sequence of DCT, CDDP and GEM. Patients with unresectable stage IIIB/IV NSCLC were eligible. All drugs were given intravenously on days 1 and 8, and repeated every 4 weeks for up to 4 cycles. DCT (30 mg/m2) was given first, followed by CDDP (40 mg/m2) and GEM (800 mg/m2). Thirty-four patients were enrolled on this study (OLCSG0101). The objective response rate was 38% (95% CI: 22-56%). As grade 3/4 hematological toxicities, neutropenia, thrombocytopenia and anemia were observed in 70%, 41% and ...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
