In Spain, the guidelines for cervical cancer screening include a recommendation to enroll in external quality control programs. The Spanish Society of Cytology (SEC) has initiated its own quality control program of gynecological cytology (QCPGC).
To describe and discuss the results of the second round of SEĆs QCPGC.
The cases are selected by a group of expert cytologists. The cases with an agreement of 75% of four cytopathologists were used. The cases were scanned with Aperio. The scanned cases not available were excluded. We included a total of 23 cases, 1 negative, 15 low grade lesions (4 ASCUS and 11 LSIL) and 7 high grade lesions (1 ASCH and 6 HSIL). Sixteen cases were studied with ThinPrep™ platform and in 7 cases the SurePath™ platform was used.
Sixteen hospitals participated. The global mean concordance was 70.6%. The mean concordance in the type of lesion was 63.1%. The concordance was 71.9% in negative diagnoses, 56.2% in ASCUS, 69.5% in LSIL and 82.8% in HSIL The discordant cases were diagnosed more frequently as negative and ASCUS. 4.4% of cases had major discordances (HSIL or ASCH versus negatives).
Our results are similar to those reported in the literature, with very few severe discordances.
