Circumstances leading to the censorship of high-grade preinvasive lesions during surveillance
| Patient identity code | Reasons for censorship | Preinvasive lesions affected (n) | Duration of surveillance (months) |
|---|---|---|---|
| PDT, photodynamic therapy. | |||
| Surveillance was discontinued in 18 high-grade preinvasive lesions when patients received treatment that might influence the outcome of the lesion. The duration of follow-up and the reasons for censorship are given for each patient. | |||

| 003 | PDT to synchronous carcinoma in the same lung | 3 | 6 |
| 003 | Chemotherapy for recurrent cancer in the contralateral lung | 1 | 10 |
| 002 | Lower lobectomy for synchronous carcinoma in the same lung, with sleeve resection and reimplantation of the upper lobe after removing proximal preinvasive lesions | 4 | 19 |
| 001 | PDT to the adjacent synchronous carcinoma | 1 | 4 |
