Abstract:
The term "synchronous tumors" is reserved for simultaneous evolution of two or more tumors with distinct sites, in which the possibility that one tumor is a metastasis of the other has been excluded. In medical practice, the involvement of two different cavitary organs of the gastrointestinal tract is very rare. We present two clinical cases of synchronous tumors: one of a malignant degeneration of a colonic polyp, associated to a jejunal tumor; the other of a patient with a gastric adenocarcinoma, who also had a bulky rectal villous tumor. We tried to find out the etiology of the tumors and the frequency of these associations, mentioned in medical literature. Immunohistochemistry investigations, genetic analysis and familial screening must complete an individualized medical approach in which the surgical technique must be adequate for each case.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
