The Louisiana Tumor Registry requires that all in situ and invasive neoplasms (cancers with behavior codes 2 or 3 as classified in the ICD-O-2 or ICD-O-3) be reported. Squamous intraepithelial neoplasia, grade III, of the vulva, vagina, and anus (VIN III, VAIN III, and AIN III) are reportable to the state registry.

All cancers of the brain and central nervous system (site codes C70.0-C72.9 and C75.1-C75.3 in the ICD-0 code books) are to be reported, regardless of behavior code

The three non-reportable diagnoses with behavior codes of 2 or 3 are:

• carcinoma in situ of the cervix

• prostatic intraepithelial neoplasia, grade III

• basal cell or squamous cell carcinoma of the skin
