Description
Summary:The objectives of this research were to evaluate cases of adenocarcinoma in situ (AIS) and early invasive adenocarcinoma (AC) of the uterine cervix in order to: (1) calculate the pathologic discordance between initial biopsies and final surgical excision specimens and (2) describe the clinical and pathologic factors associated with discordance. The University of California, Irvine and Long Beach Memorial tumor registries were used to identify 105 women with AIS and early AC treated between 1990 and 2008. The primary endpoint measured was change in diagnosis when comparing pathology from the initial biopsy to specimens from a large loop excision of the transformation zone (LLETZ), cold knife cone (CKC), or hysterectomy. The variables studied were: age, endocervical curettage (ECC), co-existing cervical intraepithelial neoplasia (CIN), race, and insurance type, as surrogates for socioeconomic status. Initial biopsies were diagnosed as AIS and AC in 44% and 56% of patients, respectively. Of the patients with a biopsy diagnosis ofAIS, 29% had a final diagnosis of AC after excisional procedure, and this discordance was not associated with any of the factors studied. A concerning high rate of discordance between colposcopic-guided punch biopsy and final pathology reinforces the current guidelines to always perform an excisional biopsy following diagnosis of AIS on punch biopsy.
