Cytological investigation sometimes makes it possible to establish tumor progression or recurrence even before the appearance of the first clinical symptoms. An increase in the expression of radiation changes with further absence of tumor elements during a follow-up should be regarded as a prognostically favorable factor of the effectiveness of radiation therapy.
细胞学检查有时甚至在出现首个临床症状之前就能确定肿瘤进展或复发情况。随访期间，若放射改变的表达增加且肿瘤成分进一步消失，则应被视为放射治疗效果的预后有利因素。
