Key result

Advanced NSCLC in men is linked to ~21% lower pretreatment serum IGF-1 levels versus controls.

  • P=0.025
  • n=80

Why the study?

The clinical significance of pretreatment serum levels of IGF-1 and IGFBP-3 in advanced stage NSCLC and their contribution to clinical evaluations was unclear.

Are pretreatment serum levels of IGF-1 and IGFBP-3 altered in men with advanced non-small cell lung cancer compared to healthy controls?

Population

80 men with smoking history of minimum 20 pack/years including 50 advanced stage NSCLC patients and 30 healthy controls

Comparison

Advanced stage NSCLC patients vs healthy controls

Design

Case-control study

Overview

Lower IGF-1 levels and ratio were associated with advanced NSCLC and histologic subtype; leaves open diagnostic utility pending prospective validation.

Structured PICO

Are pretreatment serum levels of IGF-1 and IGFBP-3 altered in men with advanced non-small cell lung cancer compared to healthy controls?

P
Population
80 men aged 40-79 years with a heavy smoking history, comprising 50 patients with advanced non-small cell lung cancer and 30 healthy controls.
C
Comparator
30 healthy controls
O
Outcome
Pretreatment serum levels of IGF-1 and IGFBP-3 and their ratiosurrogate

Main Result

Absolute Event Rate: 104.7% vs 132.4%

p-value: p=0.025

Pretreatment serum levels of IGF-1 and the IGF-1/IGFBP-3 ratio are significantly lower in men with advanced NSCLC and may serve as useful diagnostic markers.

Limitations

  • Small sample size
  • Insufficient follow-up time

Cite This Study

Çolak et al. (2012) conducted a case-control in Advanced Non-Small Cell Lung Cancer (n=80). Advanced non-small cell lung cancer vs. Healthy controls was evaluated on Pretreatment serum IGF-1 levels (ng/ml) (p=0.025). Pretreatment serum IGF-1 levels were significantly lower in men with advanced non-small cell lung cancer compared to healthy controls (104.7 vs 132.4 ng/ml, p=0.025).
