Fig. 3APrognosis according to degree of lymphatic spread and therapeutic modality. In the Kaplan-Meier survival curve, lymphoma involvement of short distance
max in patients treated with CTx and RTx had the most favorable PFS and OS (PFS,
P<0.001;
; OS,
P<0.001,
Fig. 3B). Meanwhile, involvement of long distance
max in patients received only CTx had worst PFS and OS (PFS,
P<0.001,
; OS,
P<0.001,
Fig. 3B). Lymphoma involvement of short distance
max in patients treated with only CTx and long distance
max involvement in patients who received chemotherapy combined with radiotherapy did not have significant survival differences (PFS,
P=0.431; OS,
P=0.578).
