Volume of hepatoid component and intratumor M2 macrophages predict prognosis in patients with hepatoid adenocarcinoma of the stomach.
Background: Hepatoid adenocarcinoma of the stomach (HAS), a subtype of gastric cancer (GC), includes multiple tumor components, such as enteroblastic and tubular adenocarcinoma components. However, which component mostly contributes to the aggressive behavior of HAS remains unclear. Moreover, the role of tumor-associated macrophages (TAMs) has not been explored in HAS. This study evaluated the clinical significance of the proportion of the hepatoid component within the tumor, CD163 + macrophages, and macrophage colony-stimulating factor-1 (CSF-1) in HAS.
Methods: In total, 56 cases of primary HAS were analyzed. In each case, hepatoid (HC), enteroblastic (EC), and tubular (TC) components were identified, and the ratio of HC to the entire tumor (hepatoid component ratio, HCR) was assessed to examine the correlation between HCR and clinicopathological features. Immunohistochemical staining for CD163 and CSF-1 was performed, and differences in immunohistochemical results among the three tumor components were analyzed. In each tumor component, the prognostic impact of CD163 and CSF-1 was examined.
Results: A high HCR was associated with worse overall survival (OS). CD163 + TAMs and CSF-1 immunoreactivity score in HC were significantly higher than those in the other components. High infiltration of CD163 + TAMs and a high CSF-1 immunoreactivity score in HC were associated with an aggressive course and worse OS. Multivariate analysis revealed the proportion of HC in HAS as an independent prognostic factor (HR = 3.176, p = 0.006).
Conclusions: The HCR and CD163 + TAMs may be useful prognostic predictors, and TAMs may be novel therapeutic targets of HAS.
