Pregnant women appear to have worse clinical and economic outcomes after thyroid and parathyroid surgery compared with women who are not pregnant, according to a report in the May issue of Archives of Surgery, one of the JAMA/Archives journals (see also JAMA and Archives Journals).
Thyroid and parathyroid surgery are used to treat cancer and other conditions. The incidence of thyroid cancer has increased by almost 250 percent over the last 30 years, increasing from 3.6 to 8.7 cases per 100,000 persons, according to background information in the article. The rate is almost double in pregnant women, with 14.4 cases per 100,000 persons. "Hyperthyroidism [overactive thyroid] has been reported in 0.1 percent to 0.4 percent of pregnancies. Inadequately treated hyperthyroidism during pregnancy poses significant risks to both mother and fetus," the authors write. "Outcomes after thyroid and parathyroid procedures during pregnancy have not been well characterized in the surgical literature."
SreyRam Kuy, M.D., of Yale University School of Medicine, New Haven, Conn., and United States Department of Veterans Affairs, Washington, and colleagues compared clinical and economic outcomes of thyroid and parathyroid surgery performed on 201 pregnant women (average age 29) and a group of 31,155 age-matched, non-pregnant women from 1999 to 2005. Fetal, maternal and surgical complications as well as in-hospital death, length of stay and hospital costs were measured.
Of the 201 pregnant women, 165 underwent thyroid procedures and 36 underwent parathyroid procedures. "Compared with non-pregnant women, pregnant patients had a higher rate of endocrine [relating to glands that secrete hormones](15.9 percent vs. 8.1 percent) and general complications (11.4 percent vs. 3.6 percent), longer unadjusted lengths of stay (two days vs. one day) and higher unadjusted ...
