Kirsten rat sarcoma (KRAS) oncogene mutation predicts magnitude of response and outcomes in hepatic arterial infusion pump therapy of unresectable colorectal liver metastases.

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
Background: The Kirsten rat sarcoma (KRAS) mutation predicts negative outcomes following resection of colorectal liver metastases (CRLM) and adjuvant hepatic arterial infusion (HAI) pump chemotherapy. Less is known on the effects of KRAS mutation on tumor response in patients with unresectable CRLM undergoing HAI chemotherapy with floxuridine. Methods: This is a retrospective cohort study investigating the effects of KRAS mutation on tumor response in patients with unresectable CRLM treated with HAI chemotherapy. Primary endpoint was objective response rate (ORR), secondary endpoints included overall tumor response and conversion to resectability. Results: Twenty-five patients with unresectable liver metastases from colorectal cancer were treated with HAI chemotherapy between 2017-2019. Median number of liver lesions was 12 (range, 1-59) and almost all (n=24) had prior chemotherapy before starting HAI therapy. Median number of cycles administered via HAI pump was 6 (range, 3-12). Overall decrease in liver tumor burden was 63.5% (median; range, -257-100%) with an ORR of 20/25 (80%) and 10 (40%) patients converting to resectable status. Eleven (44%) patients had KRAS positive tumors. When compared to wild-type, KRAS positive tumors had less overall percent decrease (58% Conclusions: KRAS mutational status in patients with unresectable liver metastases from colorectal cancer predicts worse response to HAI chemotherapy compared to wild type.
