Heart monitoring during lung cancer therapy may save lives

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. It is diagnosed as non-small cell lung cancer by pathological examination or cytological examination; it is assessed as locally advanced, unresectable stage III non-small cell lung cancer by imaging; 2. Plan to receive radical radiotherapy and chemotherapy ± immunotherapy; 3. Male or female between 18 and 75 years old; 4. Life expectancy ≥ 12 weeks; 5. The World Health Organization (WHO) PS score is 0 or 1; 6. Organ and bone marrow function meet the following conditions: Forced expiratory volume per second (FEV1) ≥1000 ml; absolute neutrophil count ≥1.5×10\^9/L; platelets ≥100×10\^9/L; hemoglobin ≥90 g/L ; Serum creatinine clearance calculated according to the Cockcroft-Gault formula ≥50 mL/min (Cockcroft and Gault 1976); serum bilirubin ≤1.5 times the upper limit of normal (ULN); alanine aminotransferase and aspartate aminotransferase ≤2.5 times ULN; 7. A signed informed consent form is required before proceeding with any step in the research; 8. There is an abnormality in the initial cardiac output index. Exclusion Criteria: 1. PS score 2-4; 2.
