Abstract

Objective: To describe multimodality management of lung tumors in a newly established multidisciplinary lung ablation clinic (LAC).
Methods: This retrospective cohort study included consecutive patients with primary lung cancer or pulmonary metastases evaluated in a LAC from its inception in 2/2020 to 10/2022. Thoracic surgeons, radiation oncologists, interventional pulmonologists, and thoracic radiologists experienced in interventional procedures met weekly for 1 hour with input from medical oncologists as needed to discuss imaging and management of patients referred for consideration of percutaneous image-guided thermal ablation (IGTA). Decision-making and treatment recommendation were prospectively recorded. Treatments received within 12 months after the visit were abstracted from the EMR following IRB approval.
Results: 287 patients (male, n=120 [42%]; median age 69 years; 60% ECOG 0 [range 0-3]) with primary lung cancer (n=125 [44%]) or pulmonary metastases (18% sarcoma; 11% colorectal cancer, 5% renal cell carcinoma) were reviewed in 97 LAC sessions. 38 (13%) of patients were reviewed more than once. Pre referral, 137 (48%), 126 (44%), 66 (23%), and 42 (15%) had received systemic therapy or resection, stereotactic ablative radiotherapy (SABR), or IGTA to the lung, respectively. Treatment recommendations considered 1) histology; 2) tumor biology; 3) location, size, and the number of lesions; 4) patient age, co-morbidities, and ECOG status; and 5) lesion-specific risk of complications associated with each modality. Local ablative therapy was recommended for 183 patients (64%), including surgery, SABR, and IGTA, for 24 (8.4%), 43 (15%), and 71 (25%), respectively. Two or more modalities were considered equally appropriate for 45 patients (16%). 170 patients (59%) received local therapy, including surgery for 34 (12%), SABR for 50 (17%), and IGTA for 70 (24%). Multimodal therapy occurred in 14 patients (5%), including 5 treated with SABR, then IGTA; 3 with IGTA then SABR; 3 with surgery then SABR; 2 with surgery then IGTA; 1 with surgery, then SABR, then IGTA. Systemic therapy was recommended for 51 patients (18%), including 26 (9%) who also received local therapy.
Conclusions: Multidisciplinary evaluation of patients with primary and metastatic lung tumors referred for IGTA demonstrated that 17% underwent SABR and 12% underwent resection instead, while 5% required multimodal therapy highlighting the importance of a multidisciplinary LAC.
