Abstract

Background:

We performed a systematic review and meta-analysis to determine the risk of mucocutaneous adverse events associated with lapatinib.

Patients and methods:

Eligible studies included randomized phase II and III trials of patients with solid tumors on lapatinib; describing events of stomatitis, skin rash, hand foot syndrome, pruritus and alopecia.

Results:

Our search strategy yielded 380 potentially relevant citations on lapatinib from PubMed/Medline, CENTRAL Cochrane Registry and ASCO Meeting Library. After exclusion of ineligible studies, a total of 19 clinical trials were considered eligible for the meta-analysis. The RRs of all-grade skin rash, stomatitis, hand foot syndrome and pruritus were 3.04 (95% CI 2.33–3.96; p < 0.00001), 1.67 (95% CI 1.02–2.3; p < 0.04), 4.45 (95% CI 1.15–17.19; p = 0.03), and 2.02 (95% CI 1.46–2.8; p < 0.0001), respectively. Exploratory subgroup analysis showed no effect of treatment regimen on the RRs of the relevant adverse events.

Conclusions:

Our meta-analysis has demonstrated that lapatinib is associated with a significantly increased risk of all-grade skin rash, hand foot skin reaction and pruritus. Clinicians should be aware of these risks and perform regular clinical monitoring.
