Background:
In patients operated on for non-small cell lung cancer, several guidelines recommend a follow-up based on regular clinic visits and chest CT-scans. However, evidence to support these recommendations is poor, in the absence of randomized data. The IFCT-0302 trial is a randomized multicenter trial which compared 2 follow-up programs after complete resection for a clinical stage I, II, IIIA and T4 (pulmonary nodules in the same lobe) N0-2 NSCLC (TNM 6[th] edition). We present the results of compliance with the follow-up programs for the first 2 years after randomization.
Methods:
In the CXR arm, follow-up consisted of clinic visit and chest X-rays. In the CCT arm, patients underwent clinic visit, chest X-rays, thoraco-abdominal CT scan plus fiberoptic bronchoscopy (only mandatory for squamous cell and large cell carcinomas). In both arms, procedures were repeated every 6 months after randomization during the first 2 years, and yearly until 5 years, in the absence of recurrence or second primary cancer. Supplementary procedures were allowed in case of symptoms. Primary endpoint was overall survival.
Results:
Between January 2005 and November 2012, 1775 patients were randomized (CXR: 888; CCT: 887). Patient characteristics were well balanced between the two arms : males 76.3%, median age 62 years (range: 33-87), adenocarcinomas 56.7%, stage I-II 82.1%, lobectomy or bilobectomy 86,8%, pre- and/or post-operative radiotherapy 8.7%, and pre- and/or post-operative chemotherapy 45%. Surveillance was performed in 97% of patients at 6 months, in 94% at 12 months, in 90% at 18 months and in 84% at 24 months, and did not differ between the 2 arms. Intervals between randomization and visits were respected with no difference between arms (mean +/-SD in months from randomization: 5.93 +/- 0.84; 11.95 +/- 0.98; 18.05 +/- 0.99; 24.18 +/-1.30, respectively). In the 757 patients of the CXR arm, who had a follow-up visit at 6 months and no recurrence, 754 (99.6%) had a clinic visit and 730 (96.4%) a chest X-ray. In the 706 patients of the CCT arm who had a follow-up visit at 6 months and no recurrence, 702 (99.4%) had a clinic visit, 478 (67.7%) a chest X-ray, 678 (96%) a chest CT-scan, and 342 (48.4%) a bronchoscopy. Comparable compliance results were observed at 12, 18 and 24 months. In the CXR arm, supplementary thoracic CT-scans were done in 119 patients (15.7 %) at 6 months, in 96 (14.4 %) at 12 months, in 78 (13.2%) at 18 months and in 58 (11.4%) at 24 months. Other supplementary procedures were more frequent in the CCT arm than in the CXR arm, consisting mostly of brain imaging (at 6 months, in 93 (13.2%) and 39 (5.2%) patients, respectively, p<.001).
Conclusion:
Compliance with the follow-up programs was excellent in terms of timing. Chest X-ray was often omitted in the CCT arm. In the CXR arm, supplementary CT-scans that did not lead to a diagnosis of recurrence or second primary cancer were performed in 10 to 15% of patients. In the CCT arm, the most frequently performed supplementary procedure was brain imaging.
