Table 2 PIK3CA mutations and amplification in gastric cancer--multivariable models assessing tumor size, differentiation, tumor stage, lymph node metastasis and survival status (OR and 95%CI)

From: Highly frequent PIK3CA amplification is associated with poor prognosis in gastric cancer

Factors PIK3CA mutations [OR (95% CI)] PIK3CA amplification [OR (95% CI)]
Tumor size1 0.80 (0.29-2.21) 0.88 (0.50-1.54)
Differentiation2 5.53 (0.65-47.4) 1.85 (0.86-4.02)
Tumor stage3 1.19 (0.33-4.35) 0.60 (0.31-1.17)
Lymph node metastasis 1.32 (0.13-13.6) 1.44 (0.45-4.58)
Survival status4 0.41 (0.07-2.41) 3.50 (1.36-9.00)*
  1. * Significant at P < 0.05
  2. † OR: odds ratio with 95% confidence interval
  3. 1 Tumor size (≤ 3 cm; > 3 cm and ≤ 5 cm; > 5)
  4. 2 Differentiation (well or moderate; poor or no differentiation)
  5. 3 Tumor stage (I; II; III; IV)
  6. 4 Survival status (alive; dead)
