The objectives of this study were to evaluate 1) the detection rate of atypical glandular cells of undetermined significance of endocervical cell type (AGUS‐EC) and 2) the correlation between AGUS‐EC on cytology and biopsy results using the conventional Papanicolaou (Pap) smear test vs. the ThinPrep® Pap test (TPPT). Cervical‐vaginal samples processed by the conventional Pap smear for 11 mo in 1996–1997 were identified, as were TPPTs collected for the same interval in 1997–1998. Biopsy results were compared after a 9‐mo follow‐up for both groups. There were 112 AGUS‐EC cases from 82,754 conventional Pap smears (detection rate, 0.14%) compared with 58 cases from 82,252 TPPTs (detection rate, 0.07%) (P < 0.01). Biopsies were available in 72 of 112 patients from the conventional Pap smear group and 35 of 58 patients from the TPPT groups. Five dysplastic glandular lesions/AIS were diagnosed by biopsy in the 35 patients (14.3%) from the TPPT group, compared with 2 of the 72 patients (2.8%) from the conventional Pap smear group (P < 0.05). There were no statistically significant differences between other follow‐up diagnoses for the two methods. The use of TPPT resulted in fewer cases of AGUS‐EC and better correlation with histology. The TPPT appears to be as sensitive as and more specific than the conventional Pap smear for detection of endocervical glandular lesions. Diagn. Cytopathol. 23:19–22, 2000. © 2000 Wiley‐Liss, Inc.

The caudate lobectomy combined with an additional partial hepatectomy is preferred because this approach is technically less demanding and offers an adequate surgical margin.

No clear correlation between the mutations studied and DPD activity could be established in this study. However, larger-scale prospective studies are needed to better assess the reported genotype-phenotype correlations.
