Characteristics of the prospective trials of gefitinib monotherapy for advanced EGFR mutation positive non-small cell lung cancers (NSCLC)
Publication source and year (reference) | Gefitinib 250 mg a day treatment | Number of patients (1st line/2nd line) | Country of origin | EGFR mutation analysis |
---|---|---|---|---|
Inoue 2006 (43) | 1st line therapy (chemotherapy naive patients) | 16 (16/0) | Japan | PCR amplification and sequence of exons 18–23 |
Asahina 2006 (44) | 16 (16/0) | Japan | PCR amplification and sequence of exons 18–21 | |
Sutani 2006 (45) | Mixed 1st and subsequent lines of therapy (both patients who had received or not prior chemotherapy) | 27 (4/23) | Japan | Peptide nucleic acid-locked nucleic acid (PNA-LNA) clamp of exons 18–21 |
Yoshida 2007 (46) | 21 (12/9) | Japan | Common fragment analysis of PCR amplification for exon 19 deletions and Cycleave real-time PCR for the L858R mutation | |
Sunaga 2007 (47) | 21 (11/10) | Japan | PCR amplification and sequence of exons 19–21 | |

EGFR, epidermal growth factor receptor; PCR, polymerase chain reaction
one of the patients received both gefitinib and erlotinib
Another prospective study by van Zandwijk et al. [48] was exluded from this analyses due to the small number of patients that received gefitinib (n=3) and lack of survival data.
