Genomic Landscape of Primary Tumor Site and Clinical Outcome for Patients with Metastatic Colorectal Cancer Receiving Standard-of-Care Chemotherapy.
Observational study in Targeted oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPrimary tumor site and genomic status are utilized for regimen selection in metastatic colorectal cancer; however, the impact on clinical practice is not well known.
objectiveWe aimed to clarify the impact of primary tumor site and genomic status on clinical practice in metastatic colorectal cancer.
methodsThe relationship between primary tumor site, genomic alterations, and clinical outcomes was evaluated in patients with untreated metastatic colorectal cancer using real-world data of a prospective observational study, SCRUM-Japan GI-SCREEN with clinical and genomic data set in 1011 patients enrolled from February 2015 to March 2017.
resultsFive hundred and sixty-one patients were eligible for this study. Patients with right-sided tumors had a significantly worse survival, left-sided tumors with wild-type RAS had favorable outcomes when treated with anti-epidermal growth factor receptor monoclonal antibodies, and cecum tumors had poor prognosis when treated with bevacizumab. The rate of gene alterations varied considerably depending on the primary site. In addition, gene alterations of KRAS, BRAF, SMAD4, or TP53 had individually different contributions to survival from site to site. KRAS, BRAF, PTEN, or SMAD4 mutations were associated with efficacy of bevacizumab or anti-epidermal growth factor receptor monoclonal antibodies.
conclusionsPrimary tumor site is a clinically useful biomarker to predict survival in patients with metastatic colorectal cancer treated with first-line chemotherapy. Moreover, the prognostic or predictive value of several gene alterations by primary tumor site should be considered in clinical practice.
