Zusammenfassung
Die CT-gesteuerte Radiofrequenzablation (RFA) primärer und sekundärer Lungentumoren ist im Begriff, sich als minimal-invasive therapeutische Option zur lokalen Kontrolle der Lungenherde zu etablieren.
Sie kommt bei einem Patientenkollektiv zur Anwendung, das entweder aufgrund der limitierten kardiopulmonalen Reserven oder sonstiger Komorbiditäten nicht für eine Vollnarkose und/oder Lungenresektion in Frage kommt, oder dessen Lungenherde in Zahl, Verteilung und Größe eine Operation nicht sinnvoll erscheinen lassen.
Die bisherigen Kurzzeitverläufe zeigen erfolgversprechende Ergebnisse.
Abstract
Assess the safety and evidence of efficacy of RFA for colorectal (CRC) lung metastases with follow up to1 year. Twenty-three patients had percutaneous RFA for 52 colorectal pulmonary metastases under fluoro-CT. Patients received IV conscious sedation and local analgesia with routine hospitalisation/monitoring for 24 h post RFA. Patients had CT scanning at 1 month and then 3 monthly with serum CEA assessment monthly and 3 monthly. All ablations were technically successful. Tumor diameter ranged from 0.3 to 4.2 cm. Pneumothorax occurred in 43% (10 of 23) of patients. Six patients required intercostal chest drain placement. Six patients had a second RFA, 4 for new lesions and 2 patients had a previously treated lesion retreated. Median admission was 2.0 days (range 1–9). Median follow-up is 428 days (range 173–829), with data reported to 1 year in this paper. Five patients died at 5, 6, 8, 8 and 12 months post RFA from extra-pulmonary (1) or widespread (4) disease. One patient developed malignant pleural effusion at 6 months after RFA. Cavitation was seen in nine treated lesions (17%), all resolved with scar tissue contraction by 12 months. Eighteen patients with CT scan follow-up at one year have 40 lesions classified as: disappeared (17), decreased (5), stable/same size (4), increased (14). Percutaneous imaging–guided RFA of multiple CRC pulmonary metastases is a minimally invasive treatment option with modest morbidity. A significant proportion of patients show good evidence of successful local control at one year.
