Perioperative Therapy Preoperative Chemotherapy Versus Chemoradiotherapy in Locally Advanced Gall Bladder Cancers
Sponsor: Tata Memorial Hospital
Summary
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.

Interventions
Gemcitabine
Those randomized to systemic chemotherapy alone will proceed to receive Chemotherapy Gemcitabine gemcitabine 1000 mg/m2delivered day 1 and 8 every 3 weeks for 4 cycles
Cisplatin
Inj. cisplatin 25 mg/m2 delivered. day 1 and 8 every 3 weeks for 4 cycles
Chemoradiation
Radiotherapy will be for 5 weeks and will be given only in the study arm. The radiation dose will be 50-55 Gy/ 25 fractions to the gross disease and 45 Gy/ 25 fractions to suspected microscopic disease along with weekly gemcitabine (300 mg/ m2).
PETCECT
All the patients will undergo PETCECT to rule out metastatic disease
Laparoscopy
Patients will be subjected to staging laparoscopy with 16b1 lymph node biopsy to rule out metastatic disease.
