[Data quality of cancer registration by Adicap codes, used by French pathologists from Paca, 2005-2006].

AIM

To assess the reliability of systematic and exhaustive cancer Adicap code registration by French pathology laboratories within the Crisap of Paca East network.

METHODS

The Adicap code includes tumour site, histology and pathology technique. A quality control programme was applied to malignant and in situ tumours with an Adicap code to assess data quality, correct errors and supply missing data, based on IARC recommendations.

RESULTS

In 2005 and 2006, 45,980 pathology examinations were entered in the Crisap of Paca East database. There was at least one Adicap code per examination, patients, surgeons and pathologists were identified and date of diagnosis was completed, as recommended by the HAS-Afaqap 2005 French pathologist professional quality control. Discrepancies between histopathology tissue and tumour site were found in 0.32% of cases (n=147), between age and histopathology in 0.04% of cases (n=19), and between genital tumour and sex in 0.01% of cases (n=3). In 2006, within 9535 subjects, dates of birth and postcodes of residence were missing, respectively, in 0.39% (n=37) and 22.46% (n=2142) of cases.

CONCLUSION

Data quality for the Adicap code database may be considered satisfactory. Extended to Paca in 2007, Crisap Paca database can now be exploited for Paca regional cancer control strategy.
