Overview
Surgery
In previously unsuspected gallbladder cancer, discovered in the surgical specimen following a routine gallbladder operation and confined to mucosa or muscle layer (T1), the majority of patients are cured and require no further surgical intervention.[1] [2] Re-exploration to resect liver tissue near the gallbladder bed or extended or formal hepatectomy and lymphadenectomy including N1 and N2 lymph node basins may be associated with delayed recurrences or extended survival in patients with stage I or II gallbladder cancer.[3] [4] Apparently localized cancers that are suspected before or during the operation can be surgically removed with a wedge of liver and lymph nodes and lymphatic tissue in the hepatoduodenal ligament. Long-term disease-free survival will occasionally be achieved. In jaundiced patients (stage III or stage IV), there should be consideration of preoperative percutaneous transhepatic biliary drainage for relief of biliary obstruction.
Implantation of the carcinoma at all port sites (including the camera site) after laparoscopic removal of an unsuspected cancer is a problem. Even for stage I cancers, the port sites must be excised completely.[5]
Unresectable Gallbladder Cancer
Unresectable gallbladder cancer is defined by the following TNM classification:
- Any T, N1, M0
- Any T, N0 or N1, M1
- Most T3, N0, M0
- T4, N0, M0
These patients are not curable. Significant symptomatic benefit can often be achieved with relief of biliary obstruction. A few patients have very slow-growing tumors and may live several years.
