Background The association between natural killer (NK) cells and survival in colorectal
cancer (CRC) patients remains controversial. This study aimed to clarify the prognostic value …

Background Natural killer (NK) cells are important for the prognosis of multiple cancers, but
their prognostic value remains to be evaluated in patients with gastric cancer. Thus, this …

Purpose: Tumor infiltrating T lymphocytes in colorectal cancer (CRC) have prognostic
impact, but the role of natural killer (NK) cells in CRC tissue is unclear. The contribution of …

BACKGROUND Natural killer (NK) cells have a spontaneous cytotoxic capacity against
tumor cells. These cells represent a small proportion of human colon carcinoma‐infiltrating …

PURPOSE: Aim of this study has been to evaluate natural killer (NK) activity in patients with
colorectal tumors before and after curative surgery. METHODS: Forty colorectal cancer …

Background/Aims: To determine whether preoperative natural killer (NK) cell activity has any
prognostic significance in colon cancer patients. Methods: The study population consisted of …

The ability of natural killer (NK) cells to provide protection against myeloid leukemia has
been demonstrated in clinical settings. However, whether NK cells play a role in the clinical …

Abstract Background and Aim We aimed to measure the natural killer (NK) cell activity and
pro‐inflammatory cytokine levels in the peripheral blood of pancreatic cancer patients and …

Objective As the development and progression of colorectal cancer (CRC) are known to be
affected by the immune system, cell subsets such as T cells, natural killer (NK) cells, and …

Results In the multivariate regression analysis, all potential prognostic factors essentially
reflected TNM stage, and tumor resection, NK lymphocyte counts, and peripheral CD3+ and …
