The task is to decide the Hallmarks of Cancer (HOC) taxonomy of the article based on its abstract. The input is an abstract text. There are 10 topics you will need to decide whether the article is related to. Topics: sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis, genomic instability and mutation, tumor promoting inflammation, cellular energetics, avoiding immune destruction. The output should be topics from the above 10 topics, that are related to the input article. Please note one article can be related to multiple topics. Output format: provide a semicolon-separated list of relevant topics.

    INPUT: BACKGROUND &amp ; AIMS Hepatocellular carcinoma ( HCC ) is an aggressive malignancy with few treatment options . As the status of the tumour immune microenvironment can affect progression of established tumours , we evaluated potential immune mechanisms associated with survival in HCC . METHODS Immune gene expression profiles were analyzed in tumour and non-tumour liver tissues from resected HCC patients using quantitative PCR and immunohistochemistry . Tumour-infiltrating leukocytes ( TILs ) were isolated to verify the expression of immune genes and to identify proliferating TILs . These parameters were analyzed statistically in relation with patient survival and tumour phenotype ( apoptosis and proliferation ) . RESULTS The immune microenvironment within tumours was found to be heterogeneous , although globally more inert compared to the adjacent non-tumour liver tissue . Univariate analysis in 61 patients identified a group of innate immune genes whose expression within tumours is positively associated with patient survival . TNF , IL6 and CCL2 are the most significant genes , with TNF being an independent predictor of survival in multivariate analysis . The gene set includes macrophage and NK-associated molecules such as TLR4 , TLR3 , CCR2 , NCR3 . Most of these molecules are expressed by TILs . Importantly , proliferating immune cells , predominantly NK and T cells , are present in tumours of patients with longer survival , and exclusively in areas devoid of proliferating tumour cells . NK and CD8(+) T cell densities are correlated positively with tumour apoptosis , and negatively with tumour proliferation . CONCLUSIONS Hence , an inflammatory immune microenvironment within HCC tumours could be an important means to control tumour progression via TIL activation and proliferation .
