ABSTRACT

Recurrence is found in 24 to 50% in patients undergoing surgery for colorectal cancer. The main purpose of follow-up is the screening of local or metastatic recurrence. Actually, the follow- up can not be justified only if there is a real advantage for the patient. Optimal modalities of surveillance of colorectal cancers resected have not been determined. The search of liver or lung metastases is actually preferred. The same pattern is used for searching colorectal lesions after a resection of colorectal cancer and after a polypectomy. The cost/ effectiveness deontological value must be considered in the choice of further exams. However, the contribution of a cancerology follow- up is always controversial. Only prospective and randomized trials with a sufficient number of patients would prove the usefulness of a follow-up. In order to minimize the cost's problem, it is interesting to propose follow-up for a target population with a greater individual risk for recurrence

ABSTRACT

Hepatocellular carcinoma is a rapidly fatal tumor. The only hope for a cure lies in early diagnosis. It follows that an effective screening strategy should be used in high-risk populations. Screening currently relies on tumor markers such as alfa fetoproteine [AFP] and imaging modalities. Because the AFP assay lacks sensitivity and specificity in patient with small tumors, other serum markers are being evaluated
