  1. Long term survival and symptom palliation in small primary bronchial carcinomas following treatment with intraluminal radiotherapy alone.

    Article - En anglais

    Between April 1988 and December 1992,37 patients with small, previously unirradiated, primary non-small cell carcinomas of the bronchus causing symptoms due to endobronchial disease were treated at the Christie Hospital, Manchester, with a single fraction of high dose rate intraluminal radiotherapy (ILT) using the microSelectron-HDR machine.

    Small primary (SP) lesions were defined as being less than 2 cm in diameter in a direction perpendicular to the central axis of the iridium-192 treatment source.

    Fifteen patients (41%) were treated to a dose of 15 Gy and 22 patients (59%) to 20 Gy at a distance of 1 cm from the central axis of the source.

    At 6 weeks following ILT, improvement in symptoms was seen in the following percentages of patients : haemoptysis 96%, pulmonary collapse 69%, cough 55% and dyspnoea 52%. The magnitude of improvement in these symptoms was largely maintained in patients surviving to 4 months and then 12 months post-ILT.

    Median actuarial survival was 709 days, 2-year survival 49.4% and 5-year survival 14.1%. Overall, there was no significant difference in survival after treatment with 20 Gy compared with 15 Gy at 1 cm.

    At the close of study, there were four patients still alive without disease recurrence with survivals of 38,48,49 and 63 months.

    All had had biopsy-proven squamous cell carcinomas and all had been treated with 20 Gy at 1 cm. (...)
