Table 4

Comparison of histopathological parameters and tumor stage of gallbladder cancer patients between age < 45 years (𝑛=17) and age ≥ 45 years (𝑛=22).

Parameters	Age < 45 years(𝑛=17); 𝑛 (%)	Age ≥ 45 years (𝑛=22); 𝑛 (%)	𝑃 value
Histopathology
Well-differentiated tumors	4 (23.53)	15 (68.18)	0.01*
Poorly and moderately differentiated tumors	13 (76.47)	7 (31.82)
Tumor stage
Stage II	7 (36.36)	15 (65)	0.11
Stage III	10 (63.64)	7 (35)

Values are given as numbers. Differences were tested by using Fisher exact test. *Indicates statistically significant difference (𝑃 < 0.05).
