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

purposeNational guidelines define adequate axillary lymph node dissections as those yielding ≥ 10 lymph nodes (LNs). We aimed to identify the optimal LN yield among node-positive patients.

methodsUsing the National Cancer Data Base (2010-2015), we categorized node-positive patients as follows: (1) neoadjuvant chemotherapy (NAC, cN1-3 or ypN1mi-3) or (2) upfront surgery (pN1-3). A restricted cubic splines model was used to estimate LN retrieval thresholds associated with change in overall survival (OS).

results129,685 patients were identified: 21.2% NAC, 78.8% upfront surgery. Low, moderate, and high retrieval thresholds were estimated to be 1-6, 7-21, and > 21 LNs (upfront surgery), and 1-7, 8-22, and > 22 LNs (NAC). In an adjusted model, high versus low LN yield was associated with greater receipt of adjuvant chemotherapy (upfront surgery OR 1.96, p < 0.001) and greater use of adjuvant radiation (upfront surgery OR 1.08, p = 0.02; NAC OR 1.23, p = 0.002). After adjustment, high versus low LN retrieval was associated with improved OS (upfront surgery HR 0.86, p < 0.001; NAC HR 0.77, p < 0.001). Worse OS was associated with retrieving fewer LNs, likely as a result of an under-staged axilla and missed opportunity for adjuvant therapy, while better OS was independently associated with retrieval of up to approximately 20 LNs, after which survival did not improve.

conclusionIn node-positive breast cancer, the number of nodes retrieved is significantly associated with an increased positive nodal count and greater use of adjuvant therapy. Removal of approximately 20 LNs may improve survival by both more accurate nodal staging and increased adjuvant therapy use.
