After curative lung cancer surgery, there is a risk of recurrence of the primary cancer, or development of a new cancer. Historically, patients who have undergone curative lung cancer surgery have been monitored with chest radiographs (CXR). Unfortunately, 70% of such patients still die of lung cancer. As a result, there has been interest in other methods of surveillance in order to detect recurring or new cancers earlier and have more success in treating them. One such technique is Low Dose Computed Tomography (LDCT), which is currently the standard of care and surveillance at this institution. This pilot study aims to determine whether regimented, intensive, short interval LDCT surveillance leads to higher rates of detection and treatment of recurring lung cancers. The study group will be followed up according to a regimented surveillance program using LDCT. The study group will be compared to a group of historical controls whose follow up after surgery was not standardized, but rather left up to the discretion of the individual surgeon. If the results of this study show improvements in detection and treatment of recurrent cancers, it will allow for a larger trial to study the effects of the LDCT surveillance program on lung cancer survival.
The study question aims to determine whether for survivors after curative surgery for Stage I and Stage II lung cancer, a structured Surveillance Program with Low Dose CT can increase the rate of detection and treatment of recurring or new cancers when compared to historical non-structured surveillance with CXR. This study will also determine if it is warranted to pursue a larger scale randomized controlled trial to further investigate optimal LDCT surveillance follow-up intervals and long-term lung cancer survival.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| LDCT Surveillance Program Group | Active Comparator | This cohort will follow a strict schedule of Low Dose Computed Tomography Imaging scans and clinical visits 3, 6, and 12 months after surgery. At each encounter, a history, physical examination, and review of the LDCT results will be performed. Patients with normal clinical and imaging findings will proceed to the next scheduled clinical encounter. Patients with abnormal findings will be managed according to predetermined algorithms. |
|
| Historical Control Group | Other | The control group will be a retrospective cohort taken from 1-year before the implementation of the LDCT surveillance program. The post-operative follow-up of these participants was not standardized, but rather left up to the discretion of the individual surgeons, and involved chest radiograph imaging as opposed to Low Dose Computed Tomography. |
