Association of Adiponectin and Vitamin D With Tumor Infiltrating Lymphocytes and Survival in Stage III Colon Cancer.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Adipocyte-derived adiponectin may play a role in the host inflammatory response to cancer.

The researchers examined the association of plasma adiponectin with the density of tumor-infiltrating lymphocytes (TILs) in colon cancers and with vitamin D, clinicopathological features, and patient survival.

Who Took Part

According to the abstract, 600 patients were involved.

PubMed indexes the participants as middle-aged adults and older adults, both men and women.

Plasma adiponectin and 25-hydroxyvitamin D [25(OH)D] were analyzed by radioimmunoassay in 600 patients with stage III colon cancer who received FOLFOX-based adjuvant chemotherapy (NCCTG N0147 [Alliance]).

How the Study Was Run

The design is described as randomized.

The patients were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

TIL densities were determined in histopathological sections.

Associations with disease-free survival (DFS), time to recurrence, and overall survival were evaluated by multivariable Cox regression adjusting for potential confounders (ie, body mass index, race, TILs, and N stage).

All statistical tests were 2-sided.

What Was Measured

The subject headings attached to it are Adiponectin, Antineoplastic Combined Chemotherapy Protocols, Body Mass Index, Chemotherapy, Adjuvant, Colonic Neoplasms, Disease-Free Survival and Fluorouracil.

What This Means in Plain Language

The paper is a randomized study of Vitamin D, K2, Magnesium and Zinc in 600 patients.

With several hundred people or more, it is a fairly large study for this kind of research.

Its findings take up roughly 7 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 2021 (JNCI cancer spectrum), a journal based in England.
