1098 Background: Retrospective studies showing improved survival in patients with metastatic breast cancer (MBC) who undergo surgical treatment of the primary tumor have been criticized for bias in favor of younger, healthier women with lower disease burden. We attempted to identify these biases in our population. Methods: Our institutional cancer registry was queried for patients with MBC from 1994-2010. Demographics, clinical, radiologic and pathologic staging, as well as treatments and outcomes were recorded. Surgical and non-surgical groups were compared for differences in overall survival (OS) and clinicopathologic variables, including comorbidities, using uni- and multivariate analysis. Results: Ninety-one patients with metastatic disease identified within 3 months of initial diagnosis were eligible. 53% (48 pts) had primary breast surgery and 47% (43 pts) did not undergo surgery. Patients in the surgery group were younger on univariate analysis (mean age 53 vs. 62, p<0.01). Neither BMI (mean 30 vs. 29 kg/m²) nor Charlson comorbidity score (mean 6 in both groups) were significantly different, p=NS. Bone metastases were more common in the surgery group (48 vs. 26%) and multiple metastases in the non-surgery group (35 vs. 17%), p<0.05. Patients in the non-surgery group had ≥ 1 visceral metastasis when compared to the surgery group (62 vs. 35%), p<0.05. Higher OS was demonstrated in the surgery group both with Kaplan Meier curves (p<0.05) and univariate analysis (mean 3 vs. 2 yrs, 95% CI 2.6, 3.7), p<0.05. Survival was higher in the surgery group (p<0.01), at 1 year, but this difference did not persist at 3 and 5 years. On multivariate analysis, only difference in age remained significant (p<0.01). Conclusions: Our study supports existing data that women with MBC who have surgical treatment of the primary tumor have an improved survivorship. However, it also suggests a bias towards increased use of surgery in patients who are younger with smaller burden of metastatic disease. We did not find a bias in favor of healthier patients. Further study to determine the mechanism and magnitude of benefit of primary tumor extirpation is still needed.

Introduction: In advanced breast cancer, local treatment is considered palliative. However, although there are some polemic opinions about the surgical treatment, some of the latest studies have emphasized that in advanced cases primary tumor resection (PTR) is related to better outcomes. This review aims to evaluate how resection of the original tumor impacts women with metastatic breast cancer, considering the most recent studies about this subject. Methods: The search was performed in MEDLINE, Scopus, PMC, Current Contents and Wiley Online Library databases; 23 articles - from 2016 to 2019 - were selected and 11 were included in this review. As inclusion criteria were considered: studies presenting outcomes about resection of the primary tumor, comparison between chemotherapy/ hormone therapy/ targeted cancer therapies and surgical intervention, studies published from 2016 to 2019 and available in English, Spanish or Portuguese. We excluded those which did not approach PTR, did not present outcomes of interest (progression-free survival comparison between PTR and systemic therapy) or only discussed systemic therapy, as well as those published before 2016. Results: It was reported in 6 studies that progression-free survival is better on those who underwent surgery. PTR was also related to longer median overall survival in women submitted to surgery, up to 16 months higher when compared to the ones who were not. Enhanced survival even pertained to surgical groups regardless of tumor size.  Conclusion: Based in the analysis, PTR in metastatic breast cancer can be related to higher overall survival.

Locoregional Therapy

PURPOSE Distant metastases are present in 6% or more of patients with newly diagnosed breast cancer. In this context, locoregional therapy for the intact primary tumor has been hypothesized to improve overall survival (OS), but clinical trials have reported conflicting results. METHODS Women presenting with metastatic breast cancer and an intact primary tumor received systemic therapy for 4-8 months; if no disease progression occurred, they were randomly assigned to locoregional therapy for the primary site (surgery and radiotherapy per standards for nonmetastatic disease) or continuing sysmetic therapy. The primary end point was OS; locoregional control and quality of life were secondary end points. The trial design provided 85% power to detect a 19.3% absolute difference in the 3-year OS rate in randomly assigned patients. The stratified log-rank test and Cox proportional hazards model were used to compare OS between arms. Cumulative incidence of locoregional progression was compared using Gray's test. Quality-of-life assessment used standard instruments. RESULTS Of 390 participants enrolled, 256 were randomly assigned: 131 to continued systemic therapy and 125 to early locoregional therapy. The 3-year OS was 67.9% without and 68.4% with early locoregional therapy (hazard ratio = 1.11; 90% CI, 0.82 to 1.52; P = .57). The median OS was 53.1 months (95% CI, 47.9 to not estimable) in the systemic therapy arm and 54.9 months (95% CI, 46.7 to not estimable) in the locoregional therapy arm. Locoregional progression was less frequent in those randomly assigned to locoregional therapy (3-year rate: 16.3% v 39.8%; P < .001). Quality-of-life measures were largely similar between arms. CONCLUSION Early locoregional therapy for the primary site did not improve survival in patients presenting with metastatic breast cancer. Although it was associated with improved locoregional control, this had no overall impact on quality of life.

AbstractThe debate about surgical resection of primary tumor (PT) in de novo metastatic breast cancer (MBC) patients persists. We explored this approach’s outcomes in patients included in a retrospective registry, named El Álamo, of breast cancer patients diagnosed in Spain (1990–2001). In this analysis we only included de novo MBC patients, 1415 of whom met the study’s criteria. Descriptive, Kaplan-Meier and Cox regression analyses were carried out. Median age was 63.1 years, 49.2% of patients had single-organ metastasis (skin/soft tissue [16.3%], bone [33.8%], or viscera [48.3%]). PT surgery (S) was performed in 44.5% of the cases. S-group patients were younger, had smaller tumors, higher prevalence of bone and oligometastatic disease, and lower prevalence of visceral involvement. With a median follow-up of 23.3 months, overall survival (OS) was 39.6 versus 22.4 months (HR = 0.59, p < 0.0001) in the S- and non-S groups, respectively. The S-group OS benefit remained statistically and clinically significant regardless of metastatic location, histological type, histological grade, hormone receptor status and tumor size. PT surgery (versus no surgery) was associated with an OS benefit suggesting that loco-regional PT control may be considered in selected MBC patients. Data from randomized controlled trials are of utmost importance to confirm these results.
