Gallbladder cancer survival is influenced by tumor stage and differentiation. Advanced tumors and vascular infiltration significantly reduce survival rates in patients with gallbladder cancer.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Gastroenterology

Context:

  • Gallbladder cancer prognosis remains incompletely understood.
  • Accurate survival data and prognostic indicators are crucial for patient management.

Purpose:

  • To determine actuarial survival rates for gallbladder cancer patients.
  • To identify key prognostic factors influencing gallbladder cancer outcomes.

Summary:

  • This study analyzed 745 gallbladder cancer cases (637 women, 108 men). Overall 10-year survival was 38%. Early-stage tumors showed 92% 10-year survival, while advanced tumors had 16% 5-year survival.
  • Tumor differentiation and vascular/lymphatic infiltration were significant prognostic factors. Well-differentiated tumors and absence of infiltration correlated with better survival.
  • Sex and ethnic origin did not impact survival rates.

Impact:

  • Identifies tumor infiltration and differentiation degree as critical independent prognostic factors in gallbladder cancer.
  • Provides essential data for risk stratification and treatment planning in gallbladder cancer patients.
  • Highlights the importance of staging and histological features for predicting patient outcomes.
