Perioperative Therapy Preoperative Chemotherapy Versus Chemoradiotherapy in Locally Advanced Gall Bladder Cancers

About the study

Locally advanced Gall bladders cancers not amenable for curative resection are often treated with chemotherapy alone which is the current standard of care. Randomized trials have shown survival benefit with combination chemotherapy in gallbladder cancers. Gallbladder cancer is not common western world and thus there is lack of evidence regarding the impact of neoadjuvant or concurrent chemo-radiation in this cancer.Use of neoadjuvant treatment with chemotherapy alone or chemoradiotherapy has shown to downsize these tumors to safely undergo R0 resection in few published studies. Also if the patients develop distant metastasis during this neoadjuvant therapy they can be spared of unnecessary surgery. In a pilot study of 28 patients by Engineer et al conducted at Tata Memorial centre treated with neoadjuvant concurrent chemoradiation the investigators could achieve R0 resectability rate 0f 47% with a median overall survival (OAS) and progression free survival (PFS) of 35 and 20 months for the patients undergoing R0 resection. In this study the investigators intend to compare the effects of using neoadjuvant chemotherapy alone vs. neoadjuvant chemoradiation and chemotherapy for locally advanced gall bladder cancers in terms of down staging and overall survival.
