Abstract
ObjectivesTo identify and evaluate the predictive factors of local recurrence in those patients who have had surgery for invasive breast cancer. Given that local recurrence is directly related with the appearance of distant metastases, and may therefore be considered the best indicator of mortality. Material and methodsA descriptive, retrospective study. A total of 66 and 93 patients who had been operated on in our center between 1996-98, for primary invasive breast cancer, having either conservative surgery or mastectomy. The variables studied are: age, size, site, side, type and hystological grade, axilla, margin, metastases and local recurrence. These variables have been related using multiple regression. ResultsThe age, size and margins are the only variables that have statistically significant differences in the descriptive analysis in both surgical groups. The levels of local recurrence were 7.7% and 9.8% at 5 years, in the conservative and radical surgery respectively (NS). ConclusionsNone of the variables studied were significantly related to the presence of local recurrence as the number of cases was too small. Although the affected margin was the variable which was closest to having significance, being able to relate this factor to a greater risk of metastases and a worse pronostic.
