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

backgroundPatients with locally advanced or metastatic colorectal cancer (CRC) display heterogeneous responses to standard-of-care therapy. Robust preclinical models of malignancy in the form of patient-derived tumor organoids (PDTOs) have recently come to the fore in tailoring patient care to a personalized medicine level. This study aimed to review the literature systematically regarding PTDOs and gauge their impact on precision medicine in the management of CRC.

methodsA PRISMA-compliant systematic review of the MEDLINE, EMBASE, Web of Science, and Cochrane Library databases was performed. The results were categorized based on the primary objective of the individual studies as follows: organoid use in predicting effective hyperthermic intraperitoneal chemotherapy (HIPEC), systemic chemotherapy in CRC, or neoadjuvant chemoradiotherapy in rectal cancer.

resultsThe literature search found 200 publications, 16 of which met the inclusion criteria. Organoid models of primary and metastatic CRC have been increasingly used to assess clinical responses to standard therapy. Marked heterogeneity exists, matching the responses observed in clinical practice with ex vivo drug and radiation screening. Repeated correlation between organoid and patient sensitivity to forms of HIPEC, systemic chemotherapy, and chemoradiotherapy has been observed.

conclusionPatient-derived tumor organoids are the latest tool in predictive translational research. Current organoid-based studies in precision medicine have shown their great potential for predicting the clinical response of patients to CRC therapy. Larger-scale, prospective data are required to fully support this exciting avenue in cancer care.
