Abstract
Oncology is and will continue to evolve resulting from a better understanding of the biology and intrinsic genetic profile of each cancer. Tumor biomarkers and targeted therapies are the new face of precision medicine, so it is essential for all physicians caring for cancer patients to understand and assist patients in understanding the role and importance of such markers and strategies to target them. This review was initiated in an attempt to identify, characterize, and discuss literature supporting clinically relevant molecular markers and interventions. The efficacy of targeting specific markers will be examined with data from clinical trials focusing on treatments for esophageal, gastric, liver, gallbladder, biliary tract, and pancreatic cancers.

Abstract
Cholangiocarcinomas are rare biliary tract tumors that are often challenging to diagnose and treat. Cholangiocarcinomas are generally categorized as intrahepatic or extrahepatic depending on their anatomic location. The majority of patients with cholangiocarcinoma do not have any of the known or suspected risk factors and present with advanced disease. The optimal evaluation and management of patients with cholangiocarcinoma requires thoughtful integration of clinical information, imaging studies, cytology and/or histology, as well as prompt multidisciplinary evaluation. The current review focuses on recent advances in the diagnosis and treatment of patients with cholangiocarcinoma and, in particular, on the role of endoscopy, surgery, transplantation, radiotherapy, systemic therapy, and liver-directed therapies in the curative or palliative treatment of these individuals.

Abstract
Cholangiocarcinomas (CCCs) are rare tumors that are derived from the epithelial cell lining of the bile ducts. They can be classified as intrahepatic, extrahepatic-perihilar and extrahepatic-distal tumors. The prognosis of CCCs is poor as, in many cases, they are diagnosed at advanced stages, at which point curative surgical resection is not possible. Furthermore, most patients will experience a tumor recurrence despite initial complete CCC resection. Therefore, alternative/additional therapeutic strategies are needed to improve tumor- and recurrence-free survival after surgery as well as tumor control in patients with advanced disease. In clinical practice, apart from systemic chemotherapies for the therapeutic management of CCCs, locoregional as well as multimodal strategies are available, including external and internal radiation therapies. This review focuses on the currently available nonsurgical therapies for patients with CCCs, alone or in combination with other modalities, and on evolving therapeutic concepts that are being explored in clinical studies.

Abstract
BACKGROUND Unsatisfying long-term survival of intrahepatic cholangiocarcinoma (ICC) triggers the clinicians searching for molecular markers, such as K-ras mutation, to tailor management strategy. Additionally, emergence of tyrosine kinase inhibitors (TKIs) brings new hope to palliate advanced ICC; whether the efficacy of TKIs is influenced by k-ras mutation is largely unknown. This study was designed to determine the prevalence of k-ras mutation and its clinical significance in ICC, as well as to pave the reference for future application of TKIs. METHODS A total of 86 patients with ICC who underwent hepatectomy were retrospectively recruited. K-ras mutation was determined by using laser capture microdissection and direct sequencing method. Association among clinicopathological variables and K-ras mutation was analyzed. Prognostic factors of ICC after hepatectomy also were determined. RESULTS Nineteen (22%) patients exhibited K-ras mutations. Seventeen had their K-ras mutations occurring at codon 12, and the remaining two occurring at codon 13 and codon 61 in one each. Perineural invasion was exclusively the variable associated with K-ras mutation (odds ratio, 6.9) using logistic regression analysis. Multivariate analysis demonstrated that resection margin, T-status, nodal metastasis, and K-ras mutation were independent prognostic factors. The median survival of ICC patients with K-ras mutation was 5.7 months compared with 19.0 months in those without K-ras mutation (P = 0.002). CONCLUSIONS The prevalence of K-ras mutations in a considerably large cohort of ICC was 22%. K-ras mutation is strongly associated with perineural invasion phenotypically. K-ras mutation is an independent prognostic factor of ICC after hepatectomy.

Abstract
The purpose of chemotherapy in patients with advanced solid cancers, including biliary tract cancer, is generally to improve the survival and quality of life of the patients. Also, adjuvant chemotherapy is expected to increase the curability of surgery in patients scheduled to undergo surgery. Most patients with unresectable biliary tract cancer develop obstructive jaundice, and biliary drainage is needed before any of the aforementioned treatments. Once jaundice is resolved by stenting of the bile duct or bilio-intestinal bypass, cholangitis often develops, leading to rapid deterioration of the patient's general condition. Therefore, the beneficial effect of chemotherapy in such patients remains controversial. A few randomized controlled trials have demonstrated the survival benefit of chemotherapy as compared with supportive care. In one of these trials, improvement of the quality of life was also confirmed. Recently, since the survival benefit of combined gemcitabine plus cisplatin therapy over gemcitabine alone has been demonstrated in randomized controlled clinical trials, this combined regimen has been recognized as a standard therapy for unresectable biliary tract cancer. A second-line regimen is now expected to be established for patients with gemcitabine-refractory biliary tract cancer, although the significance of second-line therapy remains unclear. One of the next issues in relation to chemotherapy for biliary tract cancer is the development of molecular-targeted agents; however, few large clinical trials of such agents have been conducted for biliary tract cancer. Various issues in chemotherapy for biliary tract cancer remain to be investigated, and global cooperation is necessary to conduct large clinical trials.

Abstract
Biliary tract cancers (BTCs) are a heterogeneous group of malignancies, with a historically poor prognosis as a whole. Until recently, the development of effective therapeutics was hampered by the relatively low incidence, heterogeneity in patients and tumors, and correspondingly poor clinical trial enrollments. With the publication of the landmark phase III ABC-02 trial demonstrating the superiority of gemcitabine and cisplatin combination chemotherapy, the landscape changed for the development of new agents. Despite this progress, there are currently no approved targeted agents for BTC. This review will focus on recent developments in targeted therapeutics, directed against several key signaling pathways in BTC, including epidermal growth factor receptor, angiogenesis, and the mitogen-activated protein kinase pathway. Data from recent phase I and II trials will be discussed, along with a preview of upcoming trials involving targeted therapies.

Abstract
BACKGROUND Combination chemotherapy has proven beneficial in biliary tract cancer and further improvements may be achieved by individualizing treatment based on biomarkers and by adding biological agents. We report the effect of chemotherapy with panitumumab as first-line therapy for KRAS wild-type irresectable biliary tract cancer. PATIENTS AND METHODS Patients were treated with gemcitabine 1000 mg/m(2), oxaliplatin 60 mg/m(2), and panitumumab 6 mg/kg i.v. every 2 weeks followed by two daily administrations of capecitabine 1000 mg/m(2) in 7 days. RESULTS During 22 months, 46 patients were included in a single institution. The primary end point, fraction of progression-free survival (PFS) at 6 months, was 31/42 [74%; 95% confidence interval (CI) 58% to 84%]. Forty-two patients had measurable disease. Response rate was 33% and disease control rate 86%. Median PFS was 8.3 months (95% CI 6.7-8.7 months) and median overall survival was 10.0 months (95% CI 7.4-12.7 months). Toxicity was manageable including eight cases of epidermal growth factor receptor-related skin adverse events of grade 2 or more. CONCLUSIONS Marker-driven patient selection is feasible in the systemic treatment of biliary tract cancer. Combination chemotherapy with panitumumab in patients with KRAS wild-type tumors met the efficacy criteria for future testing in a randomized trial.

Abstract
Biliary tract cancers (gallbladder cancer, intra- and extra-hepatic cholangiocarcinoma and selected periampullary cancers) accounted for 12,760 new cases of cancer in the USA in 2010. These tumors have a dismal prognosis with most patients presenting with advanced disease. Early, accurate diagnosis is essential, both for potential cure where possible and for optimal palliative therapy in all others. This review examines the currently available and emerging technologies for diagnosis and treatment of this group of diseases.

Abstract
Carcinomas of the Ampulla of Vater are rare tumors, accounting for 0.2% of gastrointestinal cancers. Compared with other biliary tract neoplasms, these tumors have a relatively favorable prognosis after surgical resection. Based on their epithelium of origin, two subtypes of ampullary carcinoma have been recently distinguished: intestinal and pancreatobiliary. This study evaluates histopathological features and outcomes of ampullary carcinoma and to compares the survival of these tumors to that of other biliary tract tumors. The chemotherapic options available for ampullary cancer are also reviewed. We analyzed data from 20 consecutive patients with ampullary carcinomas and 26 patients with other biliary tract carcinomas, observed in our Institution. Statistical analysis was performed by using either Fisher’s exact test or χ2 test for categorical variables. Median time of survival was calculated and compared using the Log-Rank test. Similar distribution of demographic characteristics and stage between ampullary and other biliary tract cancers was observed. Patients with ampullary cancer underwent surgery more frequently than other biliary cancers while chemotherapy and radiotherapy were used equally. In accordance with the literature, a longer median survival was observed in the group of ampullary carcinomas.

Abstract
It is necessary to establish effective chemotherapy to improve the survival of patients with biliary tract cancer, because most of these patients are unsuitable candidates for surgery, and even patients undergoing curative surgery often have recurrence. Recently, the combination of cisplatin plus gemcitabine was reported to show survival benefits over gemcitabine alone in randomized clinical trials conducted in the United Kingdom and Japan. Thus, the combination of cisplatin plus gemcitabine is now recognized as the standard therapy for unresectable biliary tract cancer. One of the next issues that need to be addressed is whether molecular targeted agents might also be effective against biliary tract cancer. Although some targeted agents have been investigated as monotherapy for first-line chemotherapy, none were found to exert satisfactory efficacy. On the other hand, monoclonal antibodies such as bevacizumab and cetuximab have also been investigated in combination with a gemcitabine-based regimen and have been demonstrated to show promising activity. Furthermore, clinical trials using new targeted agents for biliary tract cancer are also proposed. This cancer is a relatively rare and heterogeneous tumor consisting of cholangiocarcinoma and gallbladder carcinoma. Therefore, a large randomized clinical trial is necessary to confirm the efficacy of chemotherapy, and international collaboration is important.

Abstract
Gallbladder cancer is an aggressive tumor. Its incidence varies according to geography. Surgery is the standard treatment for localized stage but there is no standard treatment in metastatic or locally advanced disease. Because of the rarity of bile tract cancer (BTC) and gallblader carcinoma (GBC), most studies have grouped all BTC and GBC together, and there are very few GBC-specific studies. In addition, there is a paucity of randomized controlled studies in this disease with small numbers of patients and inclusion bias. One randomized trial ABC-02 was well conducted and showed a survival benefit in favor of gemcitabine (GEM)+cisplatin (CDDP), which can be regarded as the standard in locally advanced BTC. Adjuvant therapy after surgical resection is not validated. Understanding the molecular mechanisms of carcinogenesis of GBC has opened the way for the use of targeted therapies. This new treatment would improve survival and quality of life of our patients.

Abstract
BACKGROUND Patients with biliary tract cancer have a poor prognosis, and, until recently, no standard palliative chemotherapy has been defined. We aimed to investigate the efficacy and safety of cetuximab in combination with gemcitabine and oxaliplatin (GEMOX) for first-line treatment of biliary tract cancer. METHODS From Oct 1, 2006, to July 26, 2008, patients with unresectable locally advanced or metastatic biliary tract cancer were sequentially enrolled and treated at one centre in Austria. All patients received intravenous infusions of 500 mg/m(2) cetuximab on day 1, 1000 mg/m(2) gemcitabine on day 1, and 100 mg/m(2) oxaliplatin on day 2, every 2 weeks for 12 cycles. The primary outcome was overall response rate. Analysis was by intention to treat. Adverse reactions were assessed according to National Cancer Institute Common Toxicity Criteria. The study is completed and registered with ClinicalTrials.gov, number NCT01216345. FINDINGS 30 patients with median age of 68 years (IQR 62-73) were enrolled and included in the analysis. Objective response occurred in 19 patients (63%; 95% CI 56·2-69·8), of whom three (10%; 3·2-16·8) achieved complete response, and 16 (53%; 46·2-59·8) achieved partial response. Nine patients underwent potentially curative secondary resection after major response to therapy. Grade 3 adverse events were recorded in 13 patients: skin rash (n=4), peripheral neuropathy (n=4), thrombocytopenia (n=3), nausea (n=1), diarrhoea (n=1), and neutropenia (n=1); no grade 4 adverse events were recorded. INTERPRETATION Cetuximab plus GEMOX was well tolerated and had encouraging antitumour activity, leading to secondary resection in a third of patients. These findings warrant further study of cetuximab plus GEMOX in a large randomised trial.

[PMID: 20840777 PMCID: PMC2949805 DOI: 10.1186/1471-2407-10-492] [Citation(s) in RCA: 66] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2010] [Accepted: 09/14/2010] [Indexed: 12/18/2022] Open
Abstract
Background Intrahepatic cholangiocarcinoma (ICC) is the second most common type of primary liver cancer. Only few studies have focused on palliative radiotherapy used for patients who weren't suitable for resection by surgery. This study was conducted to investigate the effect of external beam radiotherapy (EBRT) for patients with unresectable ICC. Methods We identified 84 patients with ICC from December 1998 through December 2008 for retrospective analysis. Thirty-five of 84 patients received EBRT therapy five times a week (median dose, 50 Gy; dose range, 30-60 Gy, in fractions of 1.8-2.0 Gy daily; EBRT group); the remaining 49 patients comprised the non-EBRT group. Tumor response, jaundice relief, and survival rates were compared by Kaplan-Meier analysis. Patient records were reviewed and compared using Cox proportional hazard analysis to determine factors that affect survival time in ICC. Results After EBRT, complete response (CR) and partial response (PR) of primary tumors were observed in 8.6% and 28.5% of patients, respectively, and CR and PR of lymph node metastases were observed in 20% and 40% of patients. In 19 patients with jaundice, complete and partial relief was observed in 36.8% and 31.6% of patients, respectively. Median survival times were 5.1 months for the non-EBRT group and 9.5 months for the EBRT group (P = 0.003). One-and two-year survival rates for EBRT versus non-EBRT group were 38.5% versus 16.4%, and 9.6% versus 4.9%, respectively. Multivariate analysis revealed that clinical symptoms, larger tumor size, no EBRT, multiple nodules and synchronous lymph node metastases were associated with poorer prognosis. Conclusions EBRT as palliative care appears to improve prognosis and relieve the symptom of jaundice in patients with unresectable ICC.

Abstract
Biliary tract cancers (BTC), which encompass intra- and extrahepatic cholangiocarcinomas and gallbladder carcinomas, are a genetically diverse collection of cancers. Evidence suggests distinct models of molecular and pathologic progression, and a growing body of genetics data points to a heterogeneous collection of underlying mutations in key oncogenes and tumor suppressor genes. Although tumor genetics have been used to tailor individual treatment regimens and guide clinical decision making in other cancers, these principles have not been applied in BTC. Recent clinical trials with targeted therapies seem promising, although the relationships between subsets of patients with positive responses to therapy and tumor genetics remain unexplored. Here, we summarize the molecular pathogenesis and genetics of BTCs and animal modeling and relate these to recent and ongoing clinical trials with targeted agents.

Abstract
We have reviewed the pivotal presentations related to gastrointestinal malignancies from 2009 annual meeting of the American Society of Clinical Oncology with the theme of "personalizing cancer care". We have discussed the scientific findings and the impact on practice guidelines and ongoing clinical trials. Adding trastuzumab to chemotherapy improved the survival of patients with advanced gastric cancer overexpressing human epidermal growth factor receptor 2. Gemcitabine plus cisplatin has become a new standard for first-line treatment of advanced biliary cancer. Octreotide LAR significantly lengthened median time to tumor progression compared with placebo in patients with metastatic neuroendocrine tumors of the midgut. Addition of oxaliplatin to fluoropyrimidines for preoperative chemoradiotherapy in patients with stage II or III rectal cancer did not improve local tumor response but increased toxicities. Bevacizumab did not provide additional benefit to chemotherapy in adjuvant chemotherapy for stage II or III colon cancer. In patients with resected stage II colon cancer, recurrence score estimated by multigene RT-PCR assay has been shown to provide additional risk stratification. In stage IV colorectal cancer, data have supported the routine use of prophylactic skin treatment in patients receiving antibody against epidermal growth factor receptor, and the use of upfront chemotherapy as initial management in patients with synchronous metastasis without obstruction or bleeding from the primary site.

Abstract
Gallbladder cancer (GBC) represents the most common and aggressive type among the biliary tree cancers (BTCs). Complete surgical resection offers the only chance for cure; however, only 10% of patients with GBC present with early-stage disease and are considered surgical candidates. Among those patients who do undergo "curative" resection, recurrence rates are high. There are no established adjuvant treatments in this setting. Patients with unresectable or metastatic GBC have a poor prognosis. There has been a paucity of randomized phase III data in this field. A recent report demonstrated longer overall survival with gemcitabine in combination with cisplatin than with gemcitabine alone in patients with advanced or metastatic BTCs. Molecularly targeted agents are under development. In this review, we attempt to discuss the current status and key issues involved in the management of GBC.
