  • Clinical Efficacy of Crizotinib for Patients with Anaplastic Lymphoma Kinase-positive Advanced Non-small-cell Lung Cancer

    ObjectiveTo explore the therapeutic efficacy of crizotinib for patients with anaplastic lymphoma kinase (ALK)-positive advanced non-small-cell lung cancer (NSCLC). MethodsWe retrospectively analyzed the clinical data of 31 ALK-positive NSCLC patients who received crizotinib treatment between November 2012 and May 2014 in the Department of Thoracic Oncology of West China Hospital. The median age of the patients was 51 years old, and the percentage of male and female patients was 45.2% and 54.8%, respectively. Among them, 74.2% were non-smokers, 74.2% had an ECOG performance status of 0-2. Histologically, adenocarcinoma was the highest proportion of 96.8%, and one (3.2%) patient had large cell carcinoma. Fifteen (48.4%) ALK-positive patients were given crizotinib in the first-line setting, and 16 (51.6%) accepted crizotinib in the second-line and beyond. ResultsThe objective response rate (ORR) of the patients treated with crizotinib was 61.3%, and the disease control rate (DCR) was 90.3%. The median progression-free survival (time) was 10.0 months [(95% CI (2.9, 17.0) months]. The difference of ORR and DCR between the patients given crizotinib in the first-line setting and the patients given crizotinib in the second-line or beyond was not statistically significant (P=0.716 and P=0.600, respectively). The most frequent treatment-related adverse events were increased aspartate aminotransferase/alanine aminotransferase (64.5%), nausea and vomiting (35.5%), leukopenia (16.7%), vision disorder (16.1%), edema (12.9%), and diarrhea (12.9%), and most toxicities were grade 1 and 2. ConclusionThis study shows that crizotinib can increase the objective response rate and disease control rate, prolong progression-free survival time in patients with advanced ALK-positive non–small-cell lung cancer. Crizotinib has relative fewer side effects and can be tolerated by the patients.

  • Effectiveness and safety of crizotinib in the treatment of non-small cell lung cancer: a systematic review

    ObjectiveTo systematically review the efficacy and safety of crizotinib in the treatment of non-small cell lung cancer (NSCLC).MethodWe electronically searched databases including the Cochrane Library (Issue 5, 2017), PubMed, Embase, China Biology Medicine Database, China National Knowledge Internet Database, VIP Database and Wangfang Data from the establishment to May 2017. The randomized controlled trials (RCTs), non-RCTs, case series and case reports on crizotinib for NSCLC were included. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, assessed the methodological quality of included studies, then make Meta-analysis and descriptive analysis.ResultA total of 15 studies were included, including 4 RCTs, 1 non-RCT, 4 case series and 6 case reports. The results indicated that the progression-free survival time of crizotinib group was 8 months, which was better than chemotherapy group (4.6 months). The results of Meta-analysis showed that the response rate in the crizotinib group was higher than that in the chemotherapy group [RR=2.35, 95%CI (1.59, 3.46), P<0.000 1]. The one year survival rate in the crizotinib group was 74.5%-78.6%. The incidences of adverse reactions including dysopsia, dysgeusia, diarrhea, vomiting, constipation, transaminase lifts, upper respiratory tract infection, edema and dizziness in the crizotinib group were higher than those in the chemotherapy group (P<0.05), while the incidences of adverse reactions including leukopenia, thrombocytopenia, alopecia and fatigue in crizotinib group were lower than those in the chemotherapy group (P<0.05). Subgroup analysis under precision treatment showed the progression-free survival time of anaplastic lymphoma kinase (ALK)-positive group was 8 months, and it was longer than ALK-negative group of 4 months.ConclusionsBased on current evidence, crizotinib is better than chemotherapy for NSCLC. Due to limited quality of the included studies, the above conclusion needs to be verifed by more high quality studies.
