Fig. 2From: Unraveling the patterns and pathways of local recurrence of nasopharyngeal carcinoma: evidence for individualized clinical target volume delineationThe stepwise pattern and pathways of local recurrence of nasopharyngeal carcinoma. The incidence of recurrence of each anatomic site was listed in the schema. It was noteworthy that most of the recurrence of nasopharyngeal carcinoma followed a stepwise, orderly pattern, with decreased incidence of relapse as the distance from nasopharynx increased. Of note, the cases of in-situ recurrence were excluded from analysis. LVPM, Levator veli palatine muscle; TVPM, Tensor veli palatine muscleBack to article page
