Synchronous and metachronous malignant tumours expect the unexpected.

Objective: To evaluate occurrence of synchronous and metachronous malignant tumours, to find tumour types, age group, and relationship to treatment received.

Methods: Previously diagnosed 1st primary tumour cases experiencing a synchronous or metachronous tumour, seen at AOI from February 2003 to August 2009 (78 months) were included. The cases were analyzed for morphology/histology of 1st primary tumour, age and gender of patient, treatment received for first tumour, time interval between the 1st and 2nd primary tumour, morphology/histology of second tumour, and the treatment conferred for 2nd tumour.
