Background
It was unknown whether surgery for primary tumor would affect the occurrence of local symptoms caused by tumor progression in patients with de novo stage IV breast cancer (BC). Our work attempted to probe the effect of local resection on controlling local symptoms and improving the quality of life in de novo stage IV BC patients.
Methods
Our study included patients presenting with de novo stage IV BC at the Cancer Hospital of the Chinese Academy of Medical Sciences from January 2008 to December 2014. In this study, we defined a new term called “local progress/recurrence of symptoms” (LPRS) to refer to the local problems caused by tumor progression/recurrence. All the patients were grouped into surgery and non-surgery groups. The characteristics of the two groups were analyzed by Chi square and Fisher’s test. Univariate and multivariate Cox regression models were designed to evaluate independent prognostic factors.
Results
This study contained 177 patients. The follow-up deadline was April 1, 2019. The median follow-up time was 33 months (range 1–135 months). In included patients, 77 (43.5%) underwent surgery for primary tumors. Primary tumor surgery could reduce the occurrence of LPRS (relative risk/risk ratio (RR = 0.440; 95% CI 0.227–0.852; p = 0.015)) and patients without LPRS had longer OS (45 months vs 29 months, p < 0.001). In addition, patients who had only one symptom had better OS than those who had two or three symptoms (p = 0.0175).
Conclusions
The quality of life in patients with de novo stage IV breast cancer can be improved by reducing the incidence of local symptoms through primary tumor surgery.
