Lectin Receptors in Primary and Metastatic Cancer Cells.
Article in Asian Pacific journal of cancer prevention : APJCP, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThe purpose of this study was to detect the distribution of different lectin receptors in primary cancer cells as well as in the case of metastasis, as these biomolecules can potentially predict cancer development in certain tissues and systems.
methodsTo detect lectin receptors in tumors, the authors used conjugates of lectins purified by affinity chromatography with peroxidase, and studied their localization in paraffin sections of 12 cases of primary cancer and 33 of its metastases.
resultIn primary cancers and their metastases, there is a distinct mosaicity in the histotopography of individual lectins, especially peanut and soybean lectin. Mosaicity increases in metastases, which corresponds to the increase in malignancy of tumour cells. Detected cases of metastases with a decrease in mosaicity may be a sign of their monoclonality or a decrease in their malignancy. The study of lectins in the cells of cancer metastases and their comparison with the primary tumour and with each other suggests that in metastases, as a rule, not only signs of malignancy increase, but also the ability of cells to adhere and migrate. Thus, in the process of tumour growth and metastasis, there is a selection of clones of cells that are more prone to the development of new metastases.
conclusionsIt has been revealed that the growth of a primary immature tumour from the epithelium and its metastases is accompanied by sialylation of the surface of tumour cells, which leads to the fact that tumour cells are not recognized by the system of mononuclear phagocytes and this, naturally, contributes to the progression of tumour growth.
