1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeThe purpose of this study was to compare locoregional recurrence-free survival (LRFS) and disease-free survival (DFS) between patients undergoing mastectomy and immediate breast reconstruction (IBR) and those undergoing mastectomy alone.

methodsA retrospective review of patients who underwent mastectomy and immediate breast reconstruction for resectable invasive breast cancer between 2002 and 2010 at a single center was conducted. These cases were matched to patients who underwent mastectomy alone in the same time period, performed by 1:2 matching. Matching control variables included age, tumor size, axillary lymph node metastasis, and estrogen receptor status. Overall, 189 patients were identified in the IBR group, and 362 patients were matched to this group.

resultsIn the IBR group, 75 patients (39.7%) underwent conventional total mastectomy, 78 (41.3%) underwent skin-sparing mastectomy (SSM), and 36 (19.0%) underwent nipple-sparing mastectomy (NSM). The IBR group was significantly younger than the control group (41.9 and 45.1 years, respectively) (p=0.032), in spite of matching between three age groups. The DFS rates were similar between the IBR group and mastectomy alone group, at 92.0% and 89.9%, respectively, at 5-year follow-up (log-rank test, p=0.496). The 5-year LRFS was 96.2% in the IBR group and 96.4% in the mastectomy alone group (log-rank test, p=0.704), similar to data from previous reports. Subgroup analyses for SSM or NSM patients showed no differences in LRFS and DFS between the two groups. Additionally, in stage III patients, IBR did not cause an increase in recurrence.

conclusionIBR after mastectomy, including both SSM and NSM, had no negative impact on recurrence or patient survival, even in patients with advanced disease.
