Supplementary material for Shen et al.
Supplementary Fig. 1: Patients with squamous cell carcinoma-in situ (SCCis) and SCCis with follicular involvement (SCCis-foll). Patients with indicated diagnoses each year. Numbers of cases were slightly higher as some patients may have had more than one diagnosis on a particular day (associated with same accession number/report).
Supplementary Table 1: Demographics of SCCis-foll that recurred (n=63) and non-recurrent (n=630) cases matched for follow-up time.
Supplementary methods: Identification of cases, Exclusion of patients, Histologic analysis, Non-recurrent control group, Statistics
