University hospital, Chile. 53 Patients underwent reoperation with the aim of doing a lymphadenectomy and resecting the gallbladder bed. Lymph nodes and liver invasion were associated with recurrence. Survival analysis was focused on the group with subserosal infiltration because it is the largest subgroup in this study and prognosis is intermediate. Extended cholecyste- ctomy improved the prognosis of patients whose cancers were restricted to the subserosal layer.
Additional treatments are necessary to improve the results obtained with operation alone.
The studies were reviewed retrospectively. Signal intensity of the lesions were measured. Early and delayed enhancement patterns were evaluated. Dynamic MRI can help differentiate benign from malignant gallbladder lesions. TI - Lentinan potentiates immunity and prolongs the survival time of some patients.
