3.2 LC and Survival
Median follow-up was 41.9 (range 2.1-60.2, average 44.0) months. In total, 16 lesions in 11 patients suffered local progression. The median duration of LC was 35.8 (range 2.1-60.2, average 34.9) months (Figure 2). LC at 1, 3 and 5 years was 71.3%, 41.9% and 27.9%, respectively. Twenty patients died: ten (50%) due to local progression, two (10%) due to haemorrhage, four (20%) due to distant metastasis and four (20%) due to non-cancer reasons (two of cachexia, one of transfusion reaction and one of pulmonary infection). The median OS was 22.6 (range, 2.1~60.2, average 27.1) months (Figure 3). OS at 1-, 3- and 5-years was 57.7%, 23.8% and 11.9%, respectively.
