DELTA-P 0–2 — lower small-cell lung cancer risk

Band: DELTA-P 0–2 — lower small-cell lung cancer risk

Interpretation. DELTA-P 0–2 — lower small-cell lung cancer risk

Suggested management. Lower DELTA-P; still image per protocol if clinically indicated.

DELTA-P Score for SCLC Risk in LEMS: 0 — DELTA-P 0–2 — lower small-cell lung cancer risk. Interpretation: DELTA-P 0–2 — lower small-cell lung cancer risk What to do: Lower DELTA-P; still image per protocol if clinically indicated. Inputs: Age ≥50 years (+1): false; Smoking at diagnosis (or within prior 5 years for LEMS) (+1): false; Weight loss ≥5% (+1): false; Bulbar involvement (+1): false; Erectile dysfunction (+1): false; Karnofsky performance status <70 (+1): false Source: Titulaer MJ et al. Clinical Dutch-English Lambert-Eaton Myasthenic syndrome (LEMS) tumor association prediction score accurately predicts small-cell lung carcinoma. Arch Neurol. DOI: 10.1001/archneurol.2010.360. PMID: 21245427. Scope: DELTA-P awards 1 point each within 3 months of onset for age ≥50, smoking, weight loss ≥5%, bulbar involvement, erectile dysfunction, and Karnofsky performance status <70; higher scores predict SCLC association.
