Post-operative life expectancy in lung cancer patients
class | description |
---|---|
1 | death within one year after surgery |
2 | survival |
Three classification algorithms are compared and the best one is selected for its results to be analysed. Weights assigned to the classes are then adjusted, together with the scoring function, to adapt to the healthcare provider's needs.
- DGN: Diagnosis - specific combination of ICD-10 codes for primary and secondary as well multiple tumours if any (DGN3,DGN2,DGN4,DGN6,DGN5,DGN8,DGN1)
- PRE4: Forced vital capacity - FVC (numeric)
- PRE5: Volume that has been exhaled at the end of the first second of forced expiration - FEV1 (numeric)
- PRE6: Performance status - Zubrod scale (PRZ2,PRZ1,PRZ0)
- PRE7: Pain before surgery (T,F)
- PRE8: Haemoptysis before surgery (T,F)
- PRE9: Dyspnoea before surgery (T,F)
- PRE10: Cough before surgery (T,F)
- PRE11: Weakness before surgery (T,F)
- PRE14: T in clinical TNM - size of the original tumour, from OC11 (smallest) to OC14 (largest) (OC11,OC14,OC12,OC13)
- PRE17: Type 2 DM - diabetes mellitus (T,F)
- PRE19: MI up to 6 months (T,F)
- PRE25: PAD - peripheral arterial diseases (T,F)
- PRE30: Smoking (T,F)
- PRE32: Asthma (T,F)
- AGE: Age at surgery (numeric)
- Risk1Y: 1 year survival period - (T)rue value if died (T,F)
Class value (Risk1Y) is binary valued.
