Abstract

Purpose: Stromal cells in the tumor microenvironment, such as macrophages, play an active role in tumor growth and angiogenesis. However, little is known about relationships of biobehavioral factors with angiogenic cytokines and matrix metalloproteinases (MMP) produced by stromal cells. This study examined distress, MMPs, and angiogenic cytokines in ovarian cancer patients and in vitro. Experimental Design: Patients suspected of ovarian cancer completed preoperative questionnaires. At surgery, 56 were confirmed to have epithelial ovarian cancer. Tumor samples were analyzed for macrophage (CD68+) and tumor cell levels of MMP-2, MMP-9, and vascular endothelial growth factor. In vitro stimulation of isolated macrophage cells by the stress hormones norepinephrine and cortisol was done to assess effects on MMP-9. Results: Depressed patients showed significant elevations of MMP-9 in CD68+ cells, adjusting for stage (P < 0.0001). Patients with higher levels of current stress (P = 0.01), life stress over the last 6 months (P = 0.004), and general negative affect (P = 0.007) also showed significantly greater MMP-9 in CD68+ cells. In contrast, higher social support was associated with lower levels of MMP-9 (P = 0.023) and vascular endothelial growth factor (P = 0.036) in tumor cells. In vitro analyses showed that macrophage MMP-9 production could be directly enhanced (up to a 2-fold increase) by the stress hormones norepinephrine and cortisol. Conclusions: Ovarian cancer patients with elevated depressive symptoms, chronic stress, and low social support showed elevations in MMP-9 in tumor-associated macrophages. Direct in vitro enhancement of stromal MMP-9 production by stress hormones was also shown. These findings may have implications for patient outcomes in ovarian cancer.

  • Social isolation, stress, and depression are linked to biological processes that drive tumor progression and lower survival.

    “Additionally, factors such as social isolation, stress, and depression are associated with key biological processes promoting tumor progression and poorer survival.”

    From Living Well: Protocol for a web-based program to improve quality of life in rural and urban ovarian cancer survivors (2024) · cites this paper as [12]

    The Results and Discussion (page not provided) link depression and stress to elevated macrophage MMP-9, and lower social support to tumor-cell MMP-9 and VEGF—factors the paper describes as supporting angiogenesis and invasion. The Conclusion says these mechanisms could have implications for survival, but the study does not establish an association with poorer survival. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
