Abstract
Carcinoma gallbladder is associated with an overall 5‐year survival rate reported less than 5% due to late diagnosis. Advent of ultrasound scanning may help in detecting gallbladder polyps and an early gallbladder cancer. Excellent 5‐year survival (up to 100%) has been reported for Stage Ia disease and the survival has significantly improved for Stage Ib, II, and III if appropriate re‐operation is carried out soon after the incidental detection of gallbladder cancer. Laparoscopic cholecystectomy (LC) is contraindicated in the presence of gallbladder cancer. It is recommended to excise all laparoscopic port sites, at the time of re‐operation. Re‐operation for Stage II gallbladder cancer is associated with a 90–100% 3‐year survival rate. Patients with Stage III and IV tumors also benefit from an extended cholecystectomy. Patients with bulky primary tumors without lymph node metastases (T4N0) seem to have a better prognosis than those with distant lymph node metastases, and should be treated aggressively. It is advantageous to perform the appropriate extent of surgery for gallbladder cancer at the initial operation. Heightened awareness of the presence of cancer and the knowledge of appropriate management are important. For patients whose cancer is an incidental finding on pathologic review, re‐resection is indicated for all disease except Stage Ia. Radiotherapy and chemotherapy have not been found effective as an adjuvant or palliative therapy in gallbladder cancer. J. Surg. Oncol. 2006;93:690–698.
