Partial regression in primary carcinoma of the lung: does it occur?

Abstract

This immunophenotype resembles that shown in regressing skin malignancies and suggests a similar process occurring in lung cancer. Regressing lung cancers are associated with a better prognosis than matched controls (P = 0.0034), some showed radiological evidence of growth retardation and the group had an excess of the large cell undifferentiated histological type.
