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

backgroundThe role of preoperative neoadjuvant chemotherapy (NAC) in patients with resectable colorectal liver metastases (CRLM) remains undetermined. This study aimed to assess the efficacy of NAC in patients with resectable CRLM, especially in high-risk subgroups for recurrence, with special reference to synchronicity and the CRLM grade in the Japanese classification system.

methodsA retrospective analysis of a multi-institutional cohort who was diagnosed with resectable CRLM was performed. CRLM was classified into three grades (A, B, and C) according to the combination of H stage (H1: ≤ 4 lesions and ≤ 5 cm, H2: ≥ 5 lesions or > 5 cm, H3: ≥ 5 lesions and > 5 cm), nodal status of the primary tumor (pN0/1: ≤ 3 metastases, pN2: ≥ 4 metastases), and the presence of resectable extrahepatic metastases.

resultsAmong 222 patients with resectable CRLM, 97 (43.7%) had synchronous CRLM. The surgical failure-free survival (SF-FS) of patients with synchronous CRLM (without NAC) was significantly worse than that of patients with metachronous CRLM (P = 0.0264). The SF-FS of patients with Grade B/C was also significantly worse than that of Grade A (P = 0.0058). Among the 53 patients with synchronous and Grade B/C CRLM, 31 were assigned to NAC, and all of them underwent liver surgery. In this high-risk subgroup, the SF-FS and OS in the NAC group were significantly better than those in the upfront surgery group (P < 0.0001 and P = 0.0004, respectively).

conclusionsPatients with synchronous and Grade B/C CRLM could be good candidates for indication of NAC.
