Long-term mucocutaneous adverse effects of imatinib in Indian chronic myeloid leukemia patients

Abstract

Background

Short-term mucocutaneous adverse effects are well documented with imatinib. However, studies on long-term adverse effects and in the ethnic population are lacking.

Objective

To study the long-term mucocutaneous adverse effects of imatinib and factors predicting these adverse effects.

Methods

In this cross-sectional study, consenting adult chronic myeloid leukemia patients on imatinib for more than 250 days were recruited. The details of imatinib treatment were retrieved from hematology clinic records.

Results

Four hundred and thirty-eight patients who were on imatinib for a mean duration of 1820 days were recruited. A mean number of 1.42 ± 0.98 cutaneous adverse effects were seen per patient. Melasma-like pigmentation, periorbital edema, oral lichenoid reaction, cutaneous hypopigmentation, and vesicobullous eruptions were seen in 236 (53.9%), 81 (18.5%), 70 (16%), 42 (9.6%), and 12 (2.7%) patients, respectively. Drug-induced cutaneous eruptions (9.1%) and cutaneous hypopigmentation (9.6%) were seen less frequently. Cutaneous hyperpigmentation was more likely seen in younger patients (P = 0.001) and females (P < 0.001). On multivariate analysis, female gender was a significant risk factor for developing cutaneous hyperpigmentation and periorbital edema.

Conclusion

Cutaneous hyperpigmentation and periorbital edema are common long-term adverse effects of imatinib in Indian patients. Female gender is a significant risk factor for the development of both these adverse effects.
