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 hospitals' volume, specialization, availability of all oncological services, and experience in performing complex surgeries have a favorable impact on gastric cancer (GC) treatment.

aimsThe aim of this study was to compare the results of GC treatment according to the type of oncological hospital in the State of São Paulo.

methodsPatients diagnosed with GC between 2000 and 2022 in qualified hospitals for cancer treatment were evaluated by data extracted from the hospital cancer registry. Patients were assessed according to the type of hospital for cancer treatment: Oncology High Complexity Assistance Unit (UNACON) and Oncology High Complexity Care Center (CACON), which has greater complexity.

resultsAmong the 33,774 patients, 23,387 (69.2%) were treated at CACONs and 10,387 (30.8%) in UNACONs. CACON patients were younger, had a higher level of education, and had a more advanced cTNM stage compared to UNACON (all p<0.001, p<0.05). The time from diagnosis to treatment was over 60 days in 49.8% of CACON's patients and 39.4% of UNACON's (p<0.001, p<0.05). Surgical treatment was performed in 18,314 (54.2%) patients. The frequency pN0 (40.3 vs 32.4%) and pTNM stage I (23 vs 19.5%) were higher in CACON. There was no difference in overall survival (OS) between all adenocarcinoma cases treated at CACON and UNACON (9.3 vs 10.3 months, p=0.462, p>0.05). However, considering only patients who underwent curative surgery, the OS of patients treated at CACON was better (24.4 vs 18 months, p<0.001).

conclusionsPatients with GC who underwent gastrectomy at CACONs had better survival outcomes, suggesting that the centralization of complex cancer surgery may be beneficial.
