Abbreviations: Central Central type of lung cancer, Peripheral Peripheral type of lung cancer, Tumour size The value took from the surgical records, Stage Evaluated basing on the Eighth Edition of the American Joint Committee on Cancer (AJCC) guidelines, Symptom When they first found the mass on lung, Asymptomatic Asymptomatic cases, for the size of operation of case 8 was not queried, the value from preoperative imaging was took to indicate the size; the patient of umber 12 who underwent lung transplantation due to severe chronic obstructive pulmonary disease and pathological examination of the diseased lung showed tumours, but no tumour evidence was found in preoperative imaging thus the tumour location, tumour size and stage could not be judged; P-value: the associations of tumour size was assessed by One-Way ANOVA, meanwhile, other information were assessed by Pearson’s chi-squared test or Fisher’s exact test and 0.05 was considered as statistically significant results
