Alpha-fetoprotein-producing advanced colorectal cancer: a rare case report and literature review.
Review in The Journal of international medical research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Alpha-fetoprotein(AFP)-producing colorectal cancer is a rare form of colorectal cancer with a high degree of malignancy, advanced stage, strong invasiveness, poor response to treatment, rapid progression, and poor prognosis. Herein, we present the case of a middle-aged (in his 50s) male patient who underwent left neck lymph node biopsy due to "left neck lymph node enlargement for 5 months." Biopsy results revealed metastatic adenocarcinoma, and computed tomography examination of the chest and abdomen suggested a malignant tumor of the sigmoid colon with multiple metastases. Subsequently, the patient underwent colonoscopy, and the pathological result was colonic adenocarcinoma. Regarding tumor markers, serum alpha-fetoprotein (AFP) was 214 ng/mL. The patient received first- and second-line treatments for colon cancer, but progression-free survival was short. AFP was consistently elevated; after 8 months, the patient had AFP levels of 11,371.8 ng/mL, and imaging confirmed disease progression. The patient subsequently died, with an overall survival of more than 9 months. Compared with other tumor markers, AFP better reflects tumor progression in AFP-producing colorectal cancer.
