GONZALEZ REYES, Manuel et al. Diagnostic correlation study in breast cancer. Intra-operative histopathology results vs fi nal histopathology results. Cir. gen [online]. 2014, vol.36, n.3, pp.150-154. ISSN 1405-0099.

Introduction: Breast cancer ranks first in cancer incidence in women in industrialized countries, followed by cervical cancer, colon cancer and cancer of rectum. It is crucial to have a precise histopathological diagnosis, in order to optimize the chances of an accurate diagnosis and the timely and appropriate surgical management. The purpose of this study was to determine the correlation between the histopathology results diagnosed intraoperatively and the final outcome.

Methods: A review was performed on all the records of all patients on whom a definitive histological diagnosis of breast cancer was made. These histopathological findings were compared with the diagnosis that had been made intraoperatively.

Results: During the study period, 270 patients who underwent surgery for probable breast cancer and who already had an intraoperative histopathological diagnosis confi rmed with a defi nitive study were identifi ed. Both the intraoperative study and the defi nitive study agreed on the fi nal diagnosis (positive or negative were identifi ed for cancer) in 95.18% of cases. This was a signifi cant positive correlation. Thus, there was a sensitivity for intraoperative study of 85.7%; with a specifi city of 98.9% and a positive predictive value of 97.2%.

Conclusions: The diagnostic correlation clearly approaches the normal standards accepted internationally. Although it can be concluded that there is good agreement between the intraoperative and fi nal histology reports, all available tools must be used preoperatively in order to achieve a good performance in the surgery.
