Brief Summary:
The overall project aim is to study risk and outcomes following thoracic surgery by cross-linking high-quality national Swedish health-data registers for population-based investigations of individual level clinically relevant patient data.

Condition or disease Intervention/treatment
Lung Cancer Pulmonary Metastasis Surgery Procedure: Thoracic surgery

Detailed Description:

The purpose of this research project is to study risks and outcomes in patients who underwent thoracic surgery, primarily for lung cancer. We aim to establish a fundament for the conduct of nationwide population-based studies by linking patient-level data from the Swedish quality register for thoracic surgery (ThoR) and other national health-data registers maintained by the government agencies Statistics Sweden and the National Board of Health and Welfare. Cross-linking patient-level data is possible through the Personal Identity Number assigned to every individual who has resided in Sweden on a permanent basis. The Swedish Personal Identity Number is the unique identifier in all national registers.

Specifically, we aim:

  1. To analyze the association between socioeconomic factors and prognosis in patients undergoing pulmonary resection for lung cancer.
  2. To investigate the implementation of minimally invasive surgery for lung cancer in Sweden.
