Abstract
ObjectiveTo analyze the prognostic factors of breast cancer patients with isolated chest wall recurrence (ICWR) after mastectomy, and investigate the optimal treatment.
MethodsA total of 201 breast cancer patients with ICWR after mastectomy who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and the Fifth Medical Center Chinese PLA General Hospital from October 1998 to April 2018 were retrospectively analyzed. The median follow-up was 92.8 months and survival data were obtained.
ResultsAmong 201 patients with ICWR, 103 patients developed subsequent locoregional recurrence (sLRR) and 5-year cumulative sLRR rate was 49.1%; 134 patients developed distant metastasis (DM) and 5-year DM rate was 64.4%; 103 patients died, the median progression-free survival (PFS) was 17.4 months and the 5-year PFS rate was 23.2%; the median overall survival (OS) was 62.5 months and the 5-year OS rate was 52.1%. Multivariate analysis showed that the recurrence interval (HR=2.17, 95% CI: 1.26-3.73) and the locoregional treatment (HR=1.59, 95% CI: 1.05-2.40) were the independent prognostic factors for sLRR. The initial HER2 status (HR=1.60, 95% CI: 1.03-2.48) was the independent prognostic factor for DM. The recurrence interval (HR=1.99, 95% CI: 1.30-3.04), the locoregional treatment (HR=1.99, 95% CI: 1.43-2.76) and the treatment modalities after recurrence (HR=1.70, 95% CI: 1.18-2.46) were the independent prognostic factors for PFS. The initial HER2 status (HR=1.69, 95% CI: 1.02-2.81), the recurrence interval (HR=1.85, 95% CI: 1.15-2.98) and the treatment modalities after recurrence (HR=2.48, 95% CI: 1.56-3.96) were the independent prognostic factors for OS.
ConclusionsBreast cancer patients after ICWR have an optimistic OS until now, but the risk of sLRR and DM is high. Comprehensive treatment modalities including surgery, radiotherapy and systemic therapy improve the outcome of breast cancer patients with ICWR after mastectomy.
