The Centre is associated with the Department of Thoracic Surgery of the Medical University of Wroclaw and Lower-Silesian Centre for Pulmonary Diseases, Poland, while the research database constitutes a part of the National Lung Cancer Registry, administered by the Institute of Tuberculosis and Pulmonary Diseases in Warsaw, Poland.\n\n\n* Attribute Information:\n\n1.

PRE4: Forced vital capacity - FVC (numeric) \n3. PRE5: Volume that has been exhaled at the end of the first second of forced expiration - FEV1 (numeric) \n4. PRE6: Performance status - Zubrod scale (PRZ2,PRZ1,PRZ0) \n5. PRE7: Pain before surgery (T,F) \n6. PRE8: Haemoptysis before surgery (T,F) \n7. PRE9: Dyspnoea before surgery (T,F) \n8. PRE10: Cough before surgery (T,F) \n9. PRE11: Weakness before surgery (T,F) \n10. PRE14: T in clinical TNM - size of the original tumour, from OC11 (smallest) to OC14 (largest) (OC11,OC14,OC12,OC13) \n11. PRE17: Type 2 DM - diabetes mellitus (T,F) \n12. PRE19: MI up to 6 months (T,F) \n13. PRE25: PAD - peripheral arterial diseases (T,F) \n14. PRE30: Smoking (T,F) \n15. PRE32: Asthma (T,F) \n16. AGE: Age at surgery (numeric) \n17. Risk1Y: 1 year survival period - (T)rue value if died (T,F) \n\nClass Distribution: the class value (Risk1Y) is binary valued. \n\n\n", "format": "ARFF", "uploader": "Rafael G.
