Aromatase Inhibitor-Induced Carpal Tunnel Syndrome and Stenosing Tenosynovitis: A Systematic Review.

Abstract

BACKGROUND:

Although aromatase inhibitors are the first-line treatment in postmenopausal women with hormone receptor-positive breast cancer, there is increasing evidence that they can induce carpal tunnel syndrome and stenosing tenosynovitis. This systematic review summarizes the risk factors, incidence, and management for patients with aromatase inhibitor-induced carpal tunnel syndrome and stenosing tenosynovitis compared to tamoxifen or placebo.

METHODS:

A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-guided systematic review of PubMed/MEDLINE, Ovid Embase, and the Cochrane Central Register of Controlled Trials was conducted (to March 19, 2020), supplemented with Google Scholar, Plastic and Reconstructive Surgery, and The Journal of Hand Surgery. Two reviewers independently completed the primary and secondary screens and the quality appraisal.

RESULTS:

This study reviewed 577 abstracts and included 19 studies. Risk factors for aromatase inhibitor-induced carpal tunnel syndrome or stenosing tenosynovitis included hormone replacement therapy before trial entry, history of musculoskeletal symptoms, age younger than 60 years, prior chemotherapy, and body mass index greater than 25 kg/m2. The incidence can be increased up to 10 times compared to tamoxifen. Patient discontinuation of aromatase inhibitor treatment because of carpal tunnel syndrome and stenosing tenosynovitis was reported. Nonsurgical management led to complete resolution of carpal tunnel syndrome symptoms in up to 67 percent of cases. Although most aromatase inhibitor-induced stenosing tenosynovitis original studies were low quality, all recommended surgical release for symptom resolution.

CONCLUSIONS:

This study provides current knowledge of the associated risk factors, management options, and quality of literature for aromatase inhibitor-induced carpal tunnel syndrome and stenosing tenosynovitis. Early recognition can prevent self-discontinuation of an aromatase inhibitor and long-term sequelae of poorly treated carpal tunnel syndrome and stenosing tenosynovitis.
