PURPOSE Most prognostic systems for differentiated carcinoma have been designed for papillary carcinoma. OBJECTIVE To analyze the value of the existing prognostic systems for evaluating follicular carcinoma and to determine whether any of them have a better predictive effect. METHODS A total of 66 follicular carcinomas were analyzed. The following prognostic systems were studied: EORTC, AGE...

BACKGROUND Small cell lung cancer (SCLC) is usually classified using the limited and extensive definition. The tumor, node, metastasis (TNM) classification should also be applicable to SCLC, but it has only been reported in small surgical series. The current analysis looks to the impact of the TNM system on the clinical staging of SCLC and of the new International Association for the study of L...

Lung cancer is the leading cause of cancer-related deaths worldwide, with a dismal 5-year survival rate of 15%. The TNM (tumor-node-metastasis) classification system for lung cancer is a vital guide for determining treatment and prognosis. Despite the importance of accuracy in lung cancer staging, however, correct staging remains a challenging task for many radiologists. The new 7th edition of ...

The TNM staging system has been used since the early 1960's to predict breast cancer patient outcome. In an attempt to increase prognostic accuracy, many putative prognostic factors have been identified. Because the TNM stage model can not accommodate these new factors, the proliferation of factors in breast cancer has lead to clinical confusion. What is required is a new computerized prognosti...

Tumor-node-metastasis (TNM) staging is the standard system for the estimation of prognosis of breast cancer patients. However, this system does not exploit information yielded by markers of the biological aggressiveness of breast cancer and is clearly unsatisfactory for optimal-treatment decision-making and for patient counseling. We have developed a prognostic model, based on a few routinely e...
