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

backgroundRegorafenib and trifluridine/tipiracil are standard third-line chemotherapies for colorectal cancer patients, but their efficacy is limited. Anti-epidermal growth factor receptor antibody rechallenge has been reported to be promising for patients who have obtained clinical benefit from first-line cetuximab-based chemotherapy. Moreover, panitumumab showed non-inferior efficacy to cetuximab.

objectiveThis study assessed the efficacy and safety of third-line panitumumab rechallenge in patients with metastatic KRAS exon 2 wild-type metastatic colorectal cancer who obtained clinical benefit from first-line panitumumab-based chemotherapy. PATIENTS AND

methodsThis was a prospective, multicenter, phase II trial conducted from October 2013 to August 2017. Major eligibility criteria included KRAS exon 2 wild-type and achievement of complete response, partial response, or continued stable disease for at least 6 months in first-line panitumumab-based therapy. Irinotecan plus panitumumab treatment was continued until disease progression or unacceptable toxicity was observed. The primary endpoint was the 3-month progression-free survival (PFS) rate.

resultsTwenty-five patients were enrolled in this study. Their median age was 66.5 years, and the 3-month PFS rate was 50.0% (95% confidence interval 30.0-70.0). The median PFS and overall survival were 3.1 months and 8.9 months, respectively. The response rate and disease control rate were 8.3% and 50.0%, respectively. Common grade 3/4 adverse events were acneiform rash (17%), hypomagnesemia (13%), and dry skin (13%). No treatment-related deaths occurred.

conclusionIrinotecan plus panitumumab rechallenge is a promising third-line treatment regimen in patients with metastatic wild-type KRAS colorectal cancer. CLINICAL TRIAL IDENTIFICATION: UMIN000015916.
