A comparative analysis of clinicopathological characteristics and disease-free survival (DFS) outcomes in breast cancer patients: Mammograpghy vs symptomatic diagnosis.
e12018 Background: Our goal was to compare clinicopathological characteristics and DFS time among breast cancer patients diagnosed with mammography or symptoms. Methods: This was retrospective analysis of 828 patient files. Diagnosis was done with mammography or symptom,considering the followings:age,menopause,hormone and HER2 receptor,grade,histologic subtype,lymphovascular(LVI) and perineuronal invasion(PNI),adjuvant chemotheraphy,adjuvant herceptin,adjuvant hormone and adjuvant radiotheraphy use.Recurrence dates,locations and last appointment dates were noted. Results: Breast cancer was detected by mammography in 324 patients vs by sysmptom in 504.The difference in most cases between these two methods were significant,and respectively:positive ALND 30% vs 53.7% p=0.0001,LVI 13.7% vs 31.6% p=0.0001,PNI 7.2% vs 18.1% p=0.0001,adjuvant chemo 67% vs 85% p=0.0001,adjuvant hormone use 87.3% vs 82% p=0.001.However, recurrence rates did not differ sigificantly among two groups 12% vs 12.6% p=0.4.The median follow-up and DFS time was 48 and 37 months,respectively.Prognostic parameters were also analyzed.Pathologic staging p=0.002,PNI p=0.027,LVI p=0.0001,hormone receptor status p=0.0001,triple negativity p=0.016,luminal A group p=0.048 were found statistically significant on DFS.Diagnosis with mammography was found to have no statistically significant effect on DFS. Conclusions: Although patients diagnosed with mammography had better prognostic parameters,recurrence rates were similar with symptomatic patients at the time of diagnosis.At survival analysis,recurrence rates were calculated to be similar to those of symptomatic patients’ group.
