Primary intestinal non-Hodgkin's lymphoma: A clinicopathologic analysis of 81 patients

Figure 1 The survival curves stratified by the five groups according to anatomic site of origin. A: Overall survival among five groups (P = 0.219). Small intestine and ileocecal region vs rectum and multiple sites (P = 0.016); B: Event-free survival among five groups (P = 0.025).

Figure 2 The survival curves stratified by the three histologic subgroups. A: Overall survival among the three groups (P < 0.001); B: Event-free survival among the three groups (P = 0.002).

Figure 3 The survival curves stratified by the two groups according to lactate dehydrogenase levels. A: Overall survival between the two groups (P = 0.034); B: Event-free survival between the two groups (P = 0.010). LDH: Lactate dehydrogenase.
