Abstract:
The phenomenon of multiple primary malignant tumors in one patient synchronously or metachronously is no more curiosity. So, careful follow up study and early diagnosis of those lesions, based on an awareness of the possibility of the second cancer, will substantially increase the survival of these patients. We collected nine cases of multiple primary cancers according to Moertel's classification histologically proved and treated from 1985 to l992 at Kosin Medical Center. The results were as follows; 1. The average age of the patients was 60.9 years with dominance in seventh decade 2. The male to female ratio was 7: 2 with significant dominance in male. 3. The synchronous to metachronous ratio was 6: 3, in metachronous cases the average time interval between 1st and 2nd cancers was 122 months. 4. In 6 cases of synchronous cancers, there were penile cancer and hepatoma, renal cell carcinoma and bladder cancer, prostatic cancer and bladder cancer, bladder cancer and colon cancer, and prostatic cancer and lung cancer. In 3 cases of metachronous cancers, there were bladder cancer and uterine cervical cancer, bladder cancer and stomach cancer, and renal cell carcinoma and synovial sarcoma. 5. In 3 cases of metachronous cancers, adjuvant therapy was performed in 2 cases after operation including one case of chemotherapy and another case of radiotherapy.
