“…Although, there is no consensus on standard treatment for these patients, single-agent chemotherapy appears to be a reasonable choice for them. This conclusion arises from the efficacy and tolerability observed with third-generation cytotoxics (gemcitabine, vinorelbine, taxanes) as single-agent therapy in both phase II and III trials [10][11][12][13][14][15][16][17][18][19]. However, this treatment appears only justified for patients with a PS of 2, there is no recommended treatment for PS 3 or 4 ANSCLC patients [20][21][22][23].…”
