1. The malignancies must be primary in different organs.
2. Paired-organ (e.g., breast, kidney) malignancies (synchronous or metachronous) are viewed as a single primary.
3. Multiple malignant tumours originating in one organ are viewed as a single primary.
4. The lower intestine and uterus (with adnexa) are each considered single organs.
5. The malignant nature of the lesions must be confirmed histologically.
6. The lesion should be histologically proven to be non-metastatic (may not be possible).

Additional criterion—The malignancy should not have been induced by chemotherapy or radiation.
