Multiple primary cancers

Multiple malignant primary tumours are rare in cancer patients; their frequency as demonstrated by autopsies has been between 3% and 3.6%. It is rare to find more than three distinct primary cancers in an individual. This is a retrospective descriptive study covering 2 years 2022 and 2023 with a collection of 4 illustrative cases. The average age of the patients was 58. All patients had a good outcome. The synchronous tumour associations collected were: (breast and cervix ovary and lung endometrium and ovary vulva and colon). Synchronous association of primary cancers requires a strict diagnostic approach in order to distinguish metastatic forms from primary forms for better patient management.
