Lung Resection for Stage 1 Patients

Key findings

In 2017, 55% of stage 1 lung cancer patients (non-small cell lung cancer and small cell lung cancer) had surgery compared with 62% in 2013. The proportion of patients who have surgical resection varies by age, at 89% of stage 1 lung cancer patients under age 50 compared with 25% of those ages 80 and above.

Why is this important to Ontarians?

  • Surgical resection is the treatment of choice for early stage non-small cell lung cancer. Patients with stage 1 disease have the most favourable prognosis.[1]
  • A population-based study concluded that survival was favourable for resected early stage non-small cell lung cancer patients, including groups such as elderly patients and those with multiple tumours.[2]
  • Small cell lung cancer is not generally treated with surgery, as the cancer has often spread to other parts of the body at the time of diagnosis and responds better to chemotherapy and radiation therapy.[3]

Results

  • In 2017, 55% of stage 1 lung cancer patients had surgery compared with 62% in 2013.
  • Surgery volumes for stage 1 have fluctuated, with a low of 1,579 surgeries in 2013 and a high of 2,048 in 2016.
  • The proportion of patients having surgical resection varies by age, at 89% of stage 1 lung cancer patients under age 50 compared with 25% of patients ages 80 and above.

Opportunities

  • Surgery is not common for small cell lung cancer patients, because it is not appropriate care for many of those patients. Further investigation into the pathology of lung resection patients will be done by the Surgical Oncology Program.
  • Advances in treatment include preoperative radiation therapy, an emerging primary treatment for non-small cell lung cancer. This may explain the decreasing percentage of patients receiving surgery.
