‚ÄÉCircumstances leading to the censorship of high-grade preinvasive lesions during surveillance

Patient identity codeReasons for censorshipPreinvasive 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.
007Upper lobectomy for synchronous carcinoma in the same lobe119
005Radical external radiotherapy to synchronous carcinoma in the same lung28
003PDT to synchronous carcinoma in the same lung36
003Chemotherapy for recurrent cancer in the contralateral lung110
002Lower lobectomy for synchronous carcinoma in the same lung, with sleeve resection and reimplantation of the upper lobe after removing proximal preinvasive lesions419
001PDT to the adjacent synchronous carcinoma14
014Surgery to correct postoperative bronchial stricture with removal of lesion111
010Radical external radiotherapy to synchronous carcinoma in the same lung422
011Radical endobronchial radiotherapy to synchronous carcinoma in the same lung120
