Abstract

INTRODUCTION

Conventional, first-line cytotoxic chemotherapy (platinum doublets or nonplatinum doublets) has reached a plateau of a median survival of 7- 8 months in NSCLC patients. Crizotinib treatment achieve higher response rates and progression free survival compared to standard first-line and second-line chemotherapy in PROFILE 1014 and PROFILE 1007 studies and now accepted worldwide for treating ALK-positive advanced NSCLC.

METHODS

A total of 11 patients (6 males and 5 females; mean age: 50.29 ± 12.72 years; age range 30–66 years) with ALK-positive clinically advanced NSCLC who received crizotinib treatment were retrospectively evaluated in the study.

RESULTS

A total of 11 patients were enrolled in the study. Characteristics of patients are given in Table 1. Mean age was 50.29 ± 12.72 (range: 30–66 years). All patients were at stage 4 at the time of diagnosis and had previously received platin doublet regimens. A total of 3 patients had disease progression under crizotinib treatment, including brain metastasis, surrenal metastasis and primary mass progression. One patient who progressed with surrenal metastasis was died at the 6th month of crizotinib treatment. Progression free survival was 25.46±6.56 months (95% CI: 12.59-38.33 months) and overall survival was 104.17 ± 13.72 months (95% CI: 77.23-131.04 months).

DISCUSSION AND CONCLUSION

Crizotinib was well tolerated and showed promising efficacy in patients with ALK-positive, advanced NSCLC.
