Abstract:
Objective:To explore the effect of the resection of the primary lesion on the prognosis for patients with stage Ⅳ breast cancer.Methods:A total of 132 breast cancer patients who were first diagnosed as stage Ⅳ in the Hebei Cancer Hospital from June 2008 to June 2015 were divided into two groups: the primary resection group ( n=85) and the unresection group ( n=47). The influences of primary resection, timing of operation, lymph node removal or dissection and radiotherapy on the prognosis of stage Ⅳ breast cancer patients were analyzed. Results:Multivariate Logistic regression analysis showed that visceral metastasis was an independent influencing factor for primary lesion resection in stage Ⅳ breast cancer patients ( OR=2.590, 95% CI: 1.090-6.159). Multivariate Cox regression analysis showed that primary resection was an independent factor for the improvement of prognosis in stage Ⅳ breast cancer patients ( OR=0.582, 95% CI: 0.400-0.847). The median overall survival (OS) was 37.20 months in the resection group, which was higher than 24.10 months in the unresection group ( χ2=8.108, P=0.004). Among patients aged ≥50 years old, the median OS was 39.30 months in the resection group and 23.03 months in the unresection group, and the difference was statistically significant ( χ2=14.191, P<0.001). The median OS was 38.00 months in the 66 patients with the operation time from diagnosis to resection of primary lesion<6 months ( n=66), and 35.20 months for ≥6 months ( n=19) ( χ2=4.430, P=0.035), the difference was statistically significant ( χ2=4.430, P=0.035). The median OR of axillary lymph node dissection and axillary lymph node excision group were 45.37 months and 33.44 months, respectively, the difference was statistically significant ( χ2=7.832, P=0.005). The median OS of postoperative radiotherapy group and non-radiotherapy group were 44.80 months and 33.20 months, respectively, the difference was not statistically significant ( χ2=2.950, P=0.086). Conclusion:Resection of the primary lesion may prolong the survival time of some advanced breast cancer patients.
