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 The current staging system provides an anatomical classification of lung tumors ; its secondary purpose is to allow the prognostic stratification of patients into homogeneous groups after surgery . In this work , intratumoral perineural invasion , lymphatic and blood vessel invasion together with the necrosis content of the tumor exclusive of the non-small cell cancer staging system were studied . METHODS During a 4-year period , 152 patients operated for non-small cell lung cancer ( NSCLC ) at our hospital were analyzed . Mean age of patients was 55.7 +/- 10.1 years . RESULTS Overall 5-year survival was 42.2 % . Mediastinal lymph node involvement , tumor size , incomplete resection , pneumonectomy , presence of necrosis and perineural invasion were significant prognosticators ( P = 0.03 , 0.04 , 0.0001 , 0.046 , 0.0246 , &lt ; 0.0001 , respectively ) . Multivariate analysis revealed that N status , perineural invasion , and the presence of necrosis were independent prognostic factors ( P = 0.006 , P = 0.001 , P = 0.001 , respectively ) . Patients who had stage I tumor with necrosis and perineural invasion had a lower survival rate than those with stage IIIA tumor without these histopathological features ( P = 0.04 ) . The presence of these histopathological characteristics in stage IIIA patients was a sign of a poorer prognosis ( P = 0.0001 ) . CONCLUSIONS Perineural invasion and the presence of necrosis independently indicated a dismal prognosis and their prognostic power is comparable to those of the TNM classification . These factors could be candidates for better survival stratification and the indicators of the need for adjuvant therapy in early stage lung cancer patients .
