Retrospective analysis of colorectal cancer patients with metachronous initially unresectable liver metastases (and no other) achieving no evidence of disease after first-line comprehensive therapy: a multicenter real-world study.
Article in Journal of cancer research and clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
purposeTo explore the optimal timing of locoregional therapy in patients with colorectal cancer (CRC) recurrence after radical resection and initially unresectable liver metastases but no other metastases and whether maintenance therapy should be performed after achieving no evidence of disease (NED).
methodsThis study was jointly carried out in six medical institutions in China to collect the clinical data of patients with primary CRC from January 2015 to December 2021. Research participants were identified according to the inclusion criteria of this study for statistical analysis of the clinical characteristics and recurrence time.
results625 patients CRC with metachronous initially unresectable liver metastases but no other metastases were enrolled. Multivariate analysis showed that the number of metastases in the liver and the time from the start of first-line chemotherapy to locoregional therapy significantly affected the progression-free survival (PFS, P < 0.05) following the first-line treatment, and continued maintenance therapy reduced the risk of tumor progression in the patients (P < 0.05). Furthermore, stratified analysis showed that the median PFS of patients with 3-5 metastases in the liver was maximized when the time from the start of first-line chemotherapy to locoregional therapy was 3-4 months. Patients with > 6 metastases in the liver should extend the duration between the start of first-line chemotherapy and locoregional therapy to more than four months. Similarly, with the significant increase in the number of metastases in the liver, subsequent maintenance therapy significantly extended the PFS of the patients.
conclusionsThe overall therapeutic plan in patients with CRC recurrence after radical resection and initially unresectable liver metastases but no other metastases should consider the individual patients' situations, especially the number of metastases in the liver at initial recurrence.
