Figure 1From: Clinical application of tumor volume in advanced nasopharyngeal carcinoma to predict outcomeCumulative survival rates were stratified by primary tumor volume. The 3-year overall survival in subgroups with GTVprn <13 ml and ≧ 13 ml were 92% and 54%. Large GTVprn (≧ 13 ml) was associated with a significantly poorer survival (p < 0.05).Back to article page
