Brief summary: Biliary tract cancer (BTC) is rare in the West, but it is relatively high in Asia, including Korea. Currently used as the standard primary treatment in metastatic or locally advanced BTC is gemcitabine/platinum combination chemotherapy.There is no standard secondary chemotherapy recognized after the failure of the gemcitabine/platinum first line treatment. The investigators try to evaluate role of 5-FU, leucovorin, irinotecan, and oxaliplatin combination chemotherapy (FOLFIRINOX) for the patients who progressed after gemcitabine/cisplatin first line chemotherapy.

Detailed description: \<Biliary tract cancer\> Biliary tract cancer (BTC) is a common term for malignant tumors that occur in gallbladder and bile duct, the path in which bile is released. According to the anatomical location, biliary tract cancer is divided into intrahepatic cholangiocarcinoma and extrahepatic cholangiocarcinoma, and extrahepatic cholangiocarcinoma is classified as perihilar cholangiocarcinoma and distal cholangiocarcinoma. Biliary tract cancer is rare in the West, but it is relatively high in Asia, including Korea. Biliary tract cancer occurs annually in Korea, accounting for about 5,600 cases, 2.4 percent of the total cancer, and ranks sixth in deaths from cancer. Biliary tract cancer is a type of cancer that is difficult to treat because most patients are diagnosed with progressive diseases that cannot be operated. Only about a quarter of patients are diagnosed with surgical-ready conditions as a treatment where full surgical operation can be expected to complete, but the five-year survival rate for operation is poor at 8-44% due to a high recurrence after surgery.

\<Metastatic or relapsed biliary tract cancer treatment\> Chemotherapy is the main treatment in BTC, which is relapsed or metastatic status. 5- Fluorouracil (5-FU)-based treatment has been shown to improve the survival period for pancreatic and bile cancer patients compared to the optimal supportive care (5-FU/leucovorin ± etoposide 6.0 vs. 2.5 months, p \<0.01). Also, chemotherapy helped maintain the quality of life. The improvement in quality of life over a period of at least four months showed a significant difference compared to 10% in the group that received only optimal supportive care for 36% of the chemotherapy group. (p \< 0.01). Currently used as the standard primary treatment in metastatic or locally advanced BTC is gemcitabine/platinum combination chemotherapy. In a large phase III study, Gemcitabine/cisplatin significantly improved the median value of the progressive free survival (PFS) period from 5.0 months to 8.0 months, and the overall survival (OS) period from 8.1 months to 11.7 months, compared to the gemcitabine alone. If Cisplatin is not available, oxaliplatin can be considered as a merger with gemcitabine. The Gemcitabine/oxaliplatin regimen reported in the phase II and phase III studies PFS was 4.2-5.5 months, median for the OS period was 9.5-12.4 months.

\<Salvage treatment of biliary tract cancer\> To date, there is no standard secondary chemotherapy recognized after the failure of the gemcitabine/platinum primary treatment. Since BTC usually occurs at an advanced age and shows a low frequency of occurrence in the West, there are practical limitations to conducting large-scale clinical research. So far, there is no large three-phase study proving the benefits of secondary chemotherapy after the failure of gemcitabine/platinum chemotherapy. Implementation of secondary chemotherapy in actual clinicians is known to vary from country to country, depending on the medical judgment of the responsible clinician. In a large-scale retrospective study by the Association des Gastro-Enterologies Oncology (AGEO) group in France, 32.5% of the patients were treated with second line therapy, and 75% of the patients were reported in Japan. A retrospective study and a two-phase study and systematic literature review suggest that there will be a benefit from the treatment if second line treatment is selected for patients whose general health is relatively well maintained. Results of single or combination therapy using drugs such as Irinotecan, oxaliplatin, 5-FU, S-1, and capecitabine were reported in phase II and retrospective studies, yielding an average of 3.2 months of PFS, 7.7% of mean response rate, and 7.2 months of OS.

The 5-FU/leucovorin/irinotecan (FOLFIRI) therapy, along with the capecitabine/irinotecan therapy, is reported as the most commonly used secondary chemotherapy in the AGEO group in France. A treatment strategy for continuous use of FOLFIRI as a secondary treatment after the failure of Gemcitabine/oxaliplatin showed the median value for OS period of 21.9 months, and the median value for the PFS period. The PFS and OS due to the FOLFIRI was found to be 3.2 months and 8.4 months, respectively. On the other hand, the FOLFOX therapy, which combines oxaliplatin with 5-FU, showed a response rate of 21.6 % when administered as a secondary treatment after the failure of gemcitabine/cisplatin, and a median PFS of 3.1 months. A phase III study is currently underway that compares the administration of FOLFOX as a secondary treatment with the optimum support. In Korea, there is a problem with the standard reimbursement for applying to drugs prescribed to cancer patients, and in particular, cancer drugs that can be used as secondary therapy in metastatic BTC patients are limited. There is a need to improve the prognosis of BTC patients by expanding the use of various drugs that have been proven through external clinical research.

\<5-FU, leucovorin, irinotecan, and oxaliplatin combination chemotherapy (FOLFIRINOX) regimen for other cancer of BTC\> In a pre-clinical experiment, oxaliplatin and irinotecan have synergistic effects and are known to have relatively no overlap of toxic effects among, 5-FU, leucovorin, irinotecan, and oxaliplatin. The combination treatment of 5-FU/leukovorin/irinotecan/oxaliplatin (FOLFIRINOX) had a high therapeutic effect on progressive pancreatic cancer and colon cancer. In a phase III study comparing FOLFIRINOX and gemcitabine as a first line treatment in metastatic pancreatic cancer, the objective response rate (32 vs. 9%), PFS (6.4 vs. 3.3 months) and OS (11.1 vs. 6.8 months) were significantly higher in FOLFIRINOX. On the other hand, treatment-related toxicities, with a grade 3/4 of neutropenia (46 vs. 21%), febrile neutropenia (5.4 vs. 1.2%), thrombocytopenia (9.1 vs. 3.6%), sensory neuropathy (9 vs. 0%), vomiting (23 vs. 18%), and diarrhea (113 vs. 2%) were more common in FOLFIRINOX. In a phase III study comparing the 5-FU/leukovorin/irinotecan/oxaliplatin(FORFOXRI) and the 5-FU/leukovorin/irinotecan(FORFIRI) as a first line treatment in metastatic colorectal cancer, the FORFOXRI group was objective response (66 vs. 41 %), the PFS (9.8 vs. 6.9 months) and the OS (2.6 vs. 16.7 months) showed significant improvements. In pancreatic cancer, FOLFIRINOX was a treatment that was limited in patients with good general condition due to its high level of toxicity, including neutropenia, but the dose-reduction proved to be applied not only as a primary treatment but also as a secondary treatment. In a phase II study of pancreatic cancer patients in China, there was a 29% of grade 3/4 neutropenia were reported due to the treatment of modified FOLFIRINOX using oxaliplatin 68 mg/m2, irinotecan 135 mg/m2, and 5-FU injection of 2,400 mg/m2 for 46 hours, and there was no increase in mortality and febrile neutropenia. Other major grade 3 or higher toxicity levels showed improved safety profiles with thrombocytopenia (4.8%), anemia (8.1%), infection (4.8%), and elevated liver enzyme (14.5%).

\<Rationale of this trial\>

As a 2nd line treatment for metastatic BTC the assessment of modified FOLFIRINOX is supported by:

* The prognosis for metastatic BTC, which fails first line therapy, is poor and has no standardized treatment. Therefore, better treatment modalities are required to improve the survival of patients who no longer respond to first line treatment and to maintain the quality of life.
* Treatments that use irinotecan or oxaliplatin as secondary therapy for metastatic BTC have been shown in retrospective and phase II studies and are actually used in clinical practice of other countries.
* Oxaliplatin and irinotecan have synergistic effects and the FOLFIRINOX therapy, which uses both drugs together in 5-FU/leucovorin, has been shown to increase efficacy in pancreatic and colon cancer.
* The modified FOLFIRINOX, which was used with reduced dosage, indicates an acceptable toxic profile while maintaining its efficacy
