Gemcitabine with carboplatin for advanced intrahepatic cholangiocarcinoma: A study from North India Cancer Centre.

BACKGROUND

Gemcitabine plus cisplatin has been established as a standard chemotherapy regimen for advanced biliary tract cancers (BTCs) based on the phase III UK ABC-02 study, which included all types of biliary cancers. There is very limited data regarding the effectiveness of known chemotherapeutic regimens especially in IHCC.

METHODS

Records of 63 patients diagnosis of IHCC who received Gemcitabine and Carboplatin (G-C Regimen) chemotherapy as a first line were retrospectively reviewed. The primary aim of this study was to assess the response rate of gemcitabine carboplatin-based chemotherapy as a first line therapy in advanced intrahepatic cholangiocarcinoma (IHCC). The secondary objectives were to assess toxicity, progression free survival and overall survival.

RESULTS

There were 38 men and 25 women in our study with a median age of 56.75 years (range 31-78 years). Of the 38+25= 63 patients, 21 patients (33.8%) progressed, 5 patients (8.06%) had complete response, 25 patients (40.3%) had partial response, 12 patients (19.3%) had stable disease. Overall response rate was 48.36% and tumor control rate was 67.6%. Progression free survival was 5.3 months and overall survival of 10.3 months was seen. The most common grade 3-4 toxicities were anemia, neutropenia, and thrombocytopenia. Most common nonhematological toxicity was fatigue.

CONCLUSION

Gemcitabine in combination with carboplatin has activity against advanced IHCC. Our results are comparable with other gemcitabine carboplatin studies as well as gemcitabine cisplatin-based studies.
