Background: There is currently no preoperative staging/scoring system available for gall-bladder cancer. Unfortunately, in gallbladder cancer, patients manifest advanced stages of the disease. There is need for a methodology that can aid accurate preoperative staging and the subsequent treatment algorithm. We thus sought to validate a new scoring system, the Tata Memorial Hospital Staging System (TMHSS), for gallbladder cancer.

Methods: TMHSS is based on the cumulative impact of specific features of computed tomographic scan, presence or absence of jaundice, and serum cancer antigen 19–9 levels. This scoring system was first proposed in 2004. Patients with gallbladder cancer were enrolled onto the testing sample for TMHSS to ascertain its validity. A total of 335 consecutive patients with gallbladder cancer who sought care at the Tata Memorial Hospital between May 1, 2005, and December 31, 2006, were studied. Treatment was suggested on the basis of current existing protocols. Each patient was assigned a TMHSS score, and the treatment decision taken was compared with the algorithm generated for each individual score. Concurrence of the decision taken with the score generated algorithm was tested by the Kendall tau-b test.

Results: Ordinal-by-ordinal analysis of the value of the test was .75, which showed excellent concurrence and a statistically significant P value (P < .0001).

Conclusion: TMHSS provides an excellent correlative treatment plan for patients with gallbladder cancer. It has the potential to reduce unnecessary surgical explorations and to direct patients to the ideal treatment strategy, thereby offering a degree of prognostication.
