Abstract
|
BACKGROUND: Highly increased risk of injuries has been noted around the time of cancer diagnosis. Whether there is a similar increase in risk around the diagnosis of cervical cancer and its precursor lesions was unknown.
METHODS: We performed a cohort study including 3,016,307 Swedish women that participated in cervical screening during 2001 to 2012. We calculated the incidence rates (IR) of hospitalized iatrogenic or noniatrogenic injuries during the diagnostic workup, and the time interval from smear or punch biopsy until surgical treatment or 2 months after the last smear or biopsy, among women with invasive cervical cancer (ICC) or its precursor lesions. We calculated the IRs of injuries during the 2 months after a normal smear among the other women as reference. IR ratios (IRR) and 95% confidence intervals (CI) were calculated using Poisson regression.
RESULTS: Compared with other women, there was an increased rate of iatrogenic injuries during the diagnostic workup of women with ICC (IR, 0.58 per 1,000 person-months; IRR, 8.55; 95% CI, 3.69-19.80) as well as of women with cervical intraepithelial neoplasia grade 3 and adenocarcinoma in situ (IR, 0.09 per 1,000 person-months; IRR, 3.04; 95% CI, 1.73-5.34). We also found an increased rate of noniatrogenic injuries during the diagnostic workup of women with invasive cancer (IR, 0.65 per 1,000 person-months; IRR, 2.48; 95% CI, 1.30-4.47).
CONCLUSIONS: Although rare, there was an increased risk of inpatient care for iatrogenic and noniatrogenic injuries during the diagnostic workup of women with ICC.
IMPACT: Women experienced burden of medical complications and psychologic distress around diagnosis of a potential cervical cancer.
