TOPLINE:

Women with daily exposure to spironolactone for dermatologic conditions showed no higher risk of developing breast or gynecologic cancer than that of unexposed women.

METHODOLOGY:

  • Spironolactone, used off-label for several skin conditions in women, carries a warning about an increased tumor risk associated with high doses in rat models, and its antiandrogen properties have prompted hypotheses about a possible increased risk for breast or gynecologic cancers.
  • The researchers reviewed data on 420 women with a history of spironolactone use for acne, hair loss, and hirsutism and 3272 women with no spironolactone use at the authors› institution. Their mean age ranged from 42 to 63 years; the majority were White, and 38% were non-White.
  • Median spironolactone doses ranged from 25 mg to 225 mg; chart reviews included 5-year follow-up data from the first spironolactone exposure to allow time for tumor development.

TAKEAWAY:

  • A total of 37 of the 420 women exposed to spironolactone developed any tumors, as did 546 of the 3272 with no spironolactone exposure.
  • After the researchers controlled for age and race, women exposed to spironolactone were no more likely to develop a malignant tumor than a benign tumor, compared with unexposed women (odds ratio [OR], 0.48, P = .2).
  • The risk for breast or uterine cancer was not significantly different in the spironolactone and non-spironolactone groups (OR, 0.95, P > .9).

IN PRACTICE:

“Women taking spironolactone for acne, hair loss, and hirsutism and who are at low risk of breast or gynecologic cancers may be counseled to have regular gynecology follow-up, but no more frequently than the general population,” but more studies are needed to evaluate risk over longer periods of time, the researchers wrote.

SOURCE:

The lead author of the study was Rachel C. Hill, BS, a student at Weill Cornell Medical College, New York City, and Shari R. Lipner, MD, PhD, of the department of dermatology at Weill Cornell Medical College, was the corresponding author. The study was published online in The Journal of the American Academy of Dermatology.

LIMITATIONS:

The findings were limited by the retrospective design, as well as the small number of spironolactone patients analyzed, the short follow-up period, the lack of information about spironolactone courses, and the inability to control for family history of malignancy.

DISCLOSURES:

The study was supported by the National Center for Advancing Translational Sciences and a grant from the Clinical and Translational Science Center at Weill Cornell Medical College awarded to Ms. Hill. None of the authors had relevant disclosures; Dr. Lipner disclosed serving as a consultant for Ortho-Dermatologics, Eli Lilly, Moberg Pharmaceuticals, and BelleTorus Corporation.
