2. Multiple primary malignant tumors M P M T

3. M P M T
Multiple primary cancers are defined as occurrence of two or more malignancies, synchronous or metachronous, in different organs without any relation to each other

4. metachronous
M P M T
synchronous

5. synchronous M P MT
The term “synchronous” is used when the second primary cancer is diagnosed within 6 months of the primary cancer

6. metachronous M P M T
“metachronous” is used when the second primary cancer is diagnosed more than 6 months after the diagnosis of the primary cancer. 

7. Occurrence of multiple primary malignancies is still very rare

8. Prevalence of multiple primary malignancies is slowly increasing due to prolonged survival of cancer patients with advances in diagnostic and therapeutic modalities

9. The reasons may be environmental modifications, genetic predisposition or therapy induced. 

10. According to the surveillance, epidemiology, and end results; cancer registries of the National Cancer Institute and cancer survivors had a 14% higher risk of developing a new malignancy than would have been expected in the general population.

11. Females had a slightly higher relative risk than males for all subsequent cancers combined, and the most implicated sites were breast, colon, lung, and melanoma of the skin (Curtis et al., 2006).

12. The prevalence of MPMTs in one study was 0
The prevalence of MPMTs in one study was 0.99% (152/15398): 51 cases were synchronous MPMTs, and 101 cases were metachronous MPMTs. 

13. MPMTs were observed more frequently in : Head and neck tumors (5
MPMTs were observed more frequently in : Head and neck tumors (5.65%) Urinary tumors (4.19%). 

14. Despite its low incidence, the association of two malignancies in a single patient has been widely reported in the literature, while only a few cases of three malignancies have been described
