Medullary thyroid carcinoma: multivariate analysis of prognostic factors influencing survival.

Background: Medullary thyroid carcinoma (MTC) is a rare development of thyroid cancer with a no negligible mortality rate. Our aim was to determine factors that predict outcome in patients with MTC.

Methods: We reviewed the records of all patients with MTC (n=56) who underwent treatment at our institution between January 1990 and December 2000.

Predictors of positive axillary lymph nodes in breast cancer patients with metastatic sentinel lymph node.

Introduction: Breast cancer with metastatic sentinel lymph nodes (SLN) may have clinico-pathologic factors associated with the presence of positive non-sentinel axillary nodes (NSLN). The aim of the present study was to determine factors that predict involvement of NSLN in breast cancer patients with positive SLN.

Material And Methods: A prospective database search identified 80 patients who underwent SLN biopsy for invasive breast cancer between January 1999 and August 2002.
