Abstract
Backgrounds/Aims Reported incidence of extrahepatic bile duct cancer is higher in Asians than in Western populations. Korea, in particular, is one of the countries with the highest incidence rates of extrahepatic bile duct cancer in the world. Although research and innovative therapeutic modalities for extrahepatic bile duct cancer are emerging, clinical guidelines are currently unavailable in Korea. The Korean Society of Hepato-Biliary-Pancreatic Surgery in collaboration with related societies (Korean Pancreatic and Biliary Surgery Society, Korean Society of Abdominal Radiology, Korean Society of Medical Oncology, Korean Society of Radiation Oncology, Korean Society of Pathologists, and Korean Society of Nuclear Medicine) decided to establish clinical guideline for extrahepatic bile duct cancer in June 2021. Methods Contents of the guidelines were developed through subgroup meetings for each key question and a preliminary draft was finalized through a Clinical Guidelines Committee workshop. Results In November 2021, the finalized draft was presented for public scrutiny during a formal hearing. Conclusions The extrahepatic guideline committee believed that this guideline could be helpful in the treatment of patients.

Clin Transl Radiat Oncol 2023; 41:100646. [PMID: 37441542 PMCID: PMC10334123 DOI: 10.1016/j.ctro.2023.100646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 05/25/2023] [Accepted: 05/29/2023] [Indexed: 07/15/2023] Open
Abstract
Purpose To evaluate the patterns of locoregional recurrence (LRR) in patients with perihilar extrahepatic cholangiocarcinoma (PEHC) treated with radical resection and to suggest the optimal target volume for elective nodal irradiation. Methods Medical records of PEHC patients who underwent radical resection between January 2000 and September 2021 at five institutions were reviewed. Patients who were confirmed with LRR in the follow-up imaging study were included. The LRR sites were mapped onto the corresponding sites in template computed tomography images. The margin around the vascular structure was investigated to generate the clinical target volume (CTV) covering the common sites of regional recurrences. Results A total of 87 LRRs in 46 patients were identified, 29 (33.3%) of which were local recurrences and 58 (66.7%) were regional recurrences. The most common site of local recurrence was the liver resection margin (n = 16), followed by the anastomosis site (n = 8). Regional recurrences were observed most commonly in the para-aortic area (n = 13), followed by in the aortocaval space (n = 11), portal vein area (n = 11), and portocaval area (n = 9). Nodal CTV was generated by adding an individualized margin around the portal vein, aorta, common hepatic artery, celiac artery, and left gastric artery. Conclusions The LRR patterns in the resected PEHC were evaluated and specific guidelines for nodal CTV delineation were provided, which may help physicians delineating the target volume in postoperative radiotherapy for PEHC. These findings need further validation in a lager cohort.

The Potential Role of Adjuvant Chemoradiotherapy in Patients with Microscopically Positive (R1) Surgical Margins after Resection of Cholangiocarcinoma. Curr Oncol 2023; 30:4754-4766. [PMID: 37232816 PMCID: PMC10217181 DOI: 10.3390/curroncol30050358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 04/27/2023] [Accepted: 05/02/2023] [Indexed: 05/27/2023] Open
Abstract
(1) Background: Biliary tract cancers (BTCs) are a heterogeneous group of neoplasms with dismal prognosis and the role of adjuvant chemoradiotherapy in high-risk resected patients is unclear. (2) Methods: We retrospectively analyzed the outcomes of BTC patients who received curative intent surgery with microscopically positive resection margins (R1) and adjuvant chemoradioradiotherapy (CCRT) or chemotherapy (CHT) from January 2001 to December 201. (3) Results: Out of 65 patients who underwent R1 resection, 26 received adjuvant CHT and 39 adjuvant CCRT. The median recurrence-free survival (RFS) in the CHT and CHRT groups was 13.2 and 26.8 months, respectively (p = 0.41). Median overall survival (OS) was higher in the CHRT group (41.9 months) as compared to the CHT group (32.2 months), but the difference was not statistically significant (HR 0.88; p = 0.7). A promising trend in favor of CHRT was observed in N0 patients. Finally, no statistically significant differences were observed between patients undergoing adjuvant CHRT after R1 resection and patients treated with chemotherapy alone after R0 surgery. (4) Conclusions: Our study did not show a significant survival benefit with adjuvant CHRT over CHT alone in BTC patients with positive resection margins, while a promising trend was observed.

Abstract
PURPOSE To evaluate the role of adjuvant radiotherapy (RT) after curative resection in patients with extrahepatic bile duct (EHBD) cancer. METHODS Between January 2000 and December 2015, 1475 patients with EHBD cancer who underwent curative resection were accrued from 14 institutions in Korea. Among these, 959 patients did not receive any adjuvant therapy (RT(-) group), while 516 underwent postoperative RT with or without chemotherapy (RT(+) group). RESULTS The median age was 67 years. Nodal involvement was present in 482 patients (32.7%), and resection margin was involved in 293 patients (19.9%). RT(+) group had more patients with proximal tumours, advanced tumours, nodal involvement, perineural invasion, and involved resection margin than RT(-) group (all p < 0.001). With a median follow-up of 36 months, there were 211 locoregional recurrences, 307 distant metastases and 322 combined locoregional and distant failures. On multivariate analysis incorporating age, tumour location, differentiation, pT classification, pN classification, perineural invasion and resection margin, adjuvant RT was associated with improved overall survival (hazard ratio, 0.74; 95% confidence interval, 0.63-0.86; p < 0.001). When RT(+) group was separated into RT alone, concurrent chemoradiotherapy (CCRT) and CCRT followed by chemotherapy, the greatest benefit was observed in patients treated with CCRT followed by chemotherapy (hazard ratio, 0.52; 95% confidence interval, 0.41-0.68). CONCLUSIONS Adjuvant RT combined with chemotherapy improved survival outcomes of resected EHBD cancer patients. Considering the greatest benefit observed in patients receiving CCRT followed by chemotherapy, a randomised controlled trial comparing chemotherapy alone and CCRT followed by chemotherapy is urgently needed.

Abstract
INTRODUCTION The benefits of adjuvant radiotherapy (ART) for extrahepatic cholangiocarcinoma are uncertain largely because existing publications lack clear comparisons between ART and non-ART arms. METHODS PubMed, Medline, Embase, and the Cochrane library were systematically searched until December 2020. The primary endpoint was overall survival (OS). Sensitivity analysis was performed for studies with reliable comparability (i.e., no favorable prognosticators in the ART arm that could skew the data). RESULTS Twenty-three studies involving 1,731 patients with extrahepatic cholangiocarcinoma were reviewed. The overall median of all median prescribed doses was 50.4 Gy; brachytherapy or an intraoperative boost of 10-21 Gy was applied in 5 studies. The pooled 1-, 3-, and 5-year OS rates in the non-ART and ART arms were 69.2% versus 81.0%, p = 0.035; 34.3% versus 44.7%, p = 0.025; 25.6% versus 31.7%, p = 0.115, respectively. The corresponding pooled locoregional recurrence rates were 52.1% versus 34.9% (p = 0.014). The pooled rate of grade ≥3 gastrointestinal complications was 9.8%. Sensitivity analysis performed on 14 eligible studies showed that the ART arms had a lower pooled R0 rate (36.8% vs. 63.2%, p = 0.02) and a higher rate of positive lymph nodes (47.4% vs. 34.9%, p = 0.08). The pooled 1-, 3-, and 5-year OS rates in the non-ART versus ART arms of the selected studies were 78.2% versus 84.9%, p = 0.143; 38.5% versus 49.2%, p = 0.026; and 27.8% versus 34.5%, p = 0.11, respectively. CONCLUSIONS ART was shown to improve OS in all studies and in those selected for their reliable comparability.

The Role of Adjuvant Chemoradiotherapy in Nonhilar Extrahepatic Bile Duct Cancer: A Long-Term Single-Institution Analysis. Int J Radiat Oncol Biol Phys 2021; 111:395-404. [PMID: 34029643 DOI: 10.1016/j.ijrobp.2021.05.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2020] [Revised: 05/09/2021] [Accepted: 05/11/2021] [Indexed: 12/26/2022]
Abstract
PURPOSE Despite frequent use in the clinical setting, especially for patients with high-risk factors for relapse, the role of adjuvant treatment has not been clarified in nonhilar extrahepatic bile duct cancer (NH-EHBDC). The goal of this study is to identify the role of adjuvant chemoradiotherapy (CRT) in NH-EHBDC patients after radical surgery. METHODS AND MATERIALS Patients with NH-EHBDC who underwent radical surgery from July 2007 to December 2018 were reviewed retrospectively. Univariate and multivariate analyses were conducted to identify prognostic factors for locoregional recurrence-free survival (LRRFS), distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS). Subgroup analyses were performed to further identify the role of adjuvant CRT. RESULTS Three hundred twenty-eight patients were accrued. At a median follow-up of 37.1 months (range, 1.0-144.2 months), the 3-year LRRFS, DMFS, DFS, and OS were 63.4%, 59.0%, 53.2%, and 67.5%, respectively. In multivariate analysis, adjuvant CRT was an independent prognostic factor for LRRFS, DMFS, DFS, and OS (P < .05). For patients with nodal involvement, pT3 stage, tumor size ≥ 5 cm, poorly differentiated tumor, and R1 resection, adjuvant CRT significantly improved DFS (P < .05). CONCLUSIONS In patients with NH-EHBDC, adjuvant CRT significantly improved LRRFS and DFS. For patients with risk factors such as nodal involvement, pT3 stage, poorly differentiated tumor, tumor size ≥ 5 cm, or R1 resection, adjuvant CRT might contribute to improve treatment outcomes.

Abstract
BACKGROUND Adjuvant (chemo)radiotherapy (A(C)RT) may be an important supplement to surgery for extrahepatic cholangiocarcinoma (EHCC). However, whether all patients would achieve benefits from A(C)RT and which adjuvant regimen, adjuvant radiotherapy (ART) or adjuvant chemoradiotherapy (ACRT), would be preferred, are still undetermined. The low incidence of EHCC makes it difficult to carry out randomized controlled trials (RCTs); therefore, almost all clinical studies on radiotherapy are retrospective. We have conducted a meta-analysis of these retrospective studies. METHODS We conducted a meta-analysis of current retrospective studies using PubMed, Embase, and ClinicalTrials databases. All studies published in English that were related to A(C)RT and which analyzed overall survival (OS), disease-free survival (DFS), or locoregional recurrence-free survival (LRFS) were included. Estimated hazard ratios (HRs) were calculated for OS, DFS, and LRFS. RESULTS Data from eight studies including 685 patients were included. Our analysis showed that A(C)RT significantly improved OS (HR 0.69, 95% confidence interval (CI) 0.48-0.97, P=0.03), DFS (HR 0.60, 95% CI 0.47-0.76, P<0.0001), and LRFS (HR 0.27, 95% CI 0.17-0.41, P<0.00001) of EHCC overall. In subgroups, patients with microscopically positive resection margin (R1) could achieve a benefit from A(C)RT (HR 0.44, 95% CI 0.27-0.72, P=0.001). No statistically OS difference was observed in negative resection margin (R0) subgroup (HR 0.98, 95% CI 0.30-3.19, P=0.98).Significant OS benefit was found in patients who received concurrent ACRT (HR 0.40, 95% CI 0.26-0.62, P<0.0001), while the result of ART without chemotherapy showed no significant benefit (HR 1.14, 95% CI 0.29-4.50, P=0.85). In the distal cholangiocarcinoma subgroup, no significant difference was seen when ACRT and ART were included (HR 0.61, 95% CI 0.14-2.72, P=0.52), but a significant difference was seen when analyzing the concurrent ACRT only (HR 0.29, 95% CI 0.13-0.64, P=0.002). CONCLUSIONS A(C)RT may improve OS, DFS, and LRFS in EHCC patients, especially in those with R1 resection margins. ACRT may be superior to ART especially in distal patients.

Ann Gastroenterol Surg 2020; 4:455-463. [PMID: 32724890 PMCID: PMC7382438 DOI: 10.1002/ags3.12345] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Revised: 04/03/2020] [Accepted: 04/15/2020] [Indexed: 01/04/2023] Open
Abstract
AIM This study evaluated the effects of postoperative adjuvant chemoradiotherapy (A-CRT) for positive hepatic ductal margin (HM+) in extrahepatic cholangiocarcinoma (EHCC). METHODS Patients with EHCC who underwent surgical resection between 2002 and 2014 were included in this retrospective study. For patients with HM+, A-CRT was conducted. The clinical effect of A-CRT for HM+ on the survival and recurrence and prognostic factors of EHCC was reviewed. RESULTS Among 340 patients, the hepatic ductal margin was negative in 296 and positive in 44. Of the 44 patients with HM+, 22 received postoperative A-CRT, and 22 did not. Hepatic stump recurrence occurred in 19 patients. The incidence was significantly higher in patients with HM+ (20%, 9/44) than in those with negative hepatic ductal margin (HM-) (3%, 10/296) (P < .001). Among the patients with HM+, the incidence was almost identical between the patients with and without A-CRT: 23% (5/22) in HM+/CRT- and 18% (4/22) in HM+/CRT+ patients (P = .999). The median survival time was 49 months in HM-, 43 months in HM+/CRT-, and 49 months in HM+/CRT+ patients. The differences were not significant among the groups. A multivariate analysis revealed CA 19-9 ≥ 300 U/mL, combined vascular resection, histologic grade G2/G3, and lymph node metastasis to be significant prognostic factors. However, the performance of postoperative A-CRT did not contribute to prolonging survival. CONCLUSION A-CRT for HM+ in patients with EHCC did not affect the survival or stump recurrence.

Abstract
Extrahepatic cholangiocarcinoma (EHCC) is a rare malignant tumor, and current treatment methods are also relatively limited. Radical surgery is the only potentially curative method for the long survival time. However, despite undergoing radical resection, prognosis remained poor due to the high recurrence rate and distant metastasis. Therefore, adjuvant chemotherapy and radiotherapy should be offered to patients who have undergone surgery. Unfortunately, the low incidence of this disease has resulted in a lack of high-level evidence to confirm the importance of adjuvant chemotherapy or radiotherapy. At present, it is still controversial whether adjuvant therapy can prolong the survival of patients after operation, especially patients with negative margins or lymph nodes. Furthermore, standard regimens of adjuvant have not been identified. This review summarizes the currently available evidence of the effect of adjuvant therapy in the management of EHCC. Ultimately, we concluded that adjuvant therapy may improve survival in high-risk (positive margin or lymph node or advanced stage) patients and adjuvant concurrent chemoradiotherapy followed by chemotherapy may be the optimum selection for them. This needs to be verified by randomized prospective clinical trials.

Abstract
Extrahepatic bile duct cancer (EBDC) is a rare malignancy that involves neoplastic changes extending from both hepatic ducts to the common bile duct. The treatment of choice is surgical resection, but the predominant pattern of initial treatment failure is locoregional recurrence. Accordingly, adjuvant radiotherapy has been administered after surgical resection based on these rationales. At this time, there is minimal evidence supporting adjuvant radiotherapy, because there have been no phase III trials evaluating its benefit. Relatively small retrospective studies have tried to compare outcomes associated with EBDC treated with or without radiotherapy. We aimed to review studies investigating adjuvant radiotherapy for resected EBDC. Because less than one-third of EBDC cases are amenable to curative resection at diagnosis, other locoregional treatment modalities need to be considered, including radiotherapy. The next aim of this review was to summarize reports of definitive radiotherapy for unresectable EBDC. Patients with advanced EBDC often experience biliary obstruction, which can lead to jaundice and progress to death. Biliary stent insertion is an important palliative procedure, but stents are prone to occlusion after subsequent ingrowth of the EBDC. Radiotherapy can be effective for maintaining the patency of inserted stents. We also reviewed the benefit of palliative radiotherapy combined with the biliary stent insertion. Lastly, we discuss the existing gaps in the evidence supporting radiotherapy in the management of EBDC.

Abstract
BACKGROUND The benefit of adjuvant chemotherapy for resectable cholangiocarcinoma remains unclear due to the lack of randomized control studies. This study aimed to investigate the possible benefit of postoperative adjuvant chemotherapy for resectable cholangiocarcinoma. DATA SOURCES Relevant research articles published before 1st March 2018 in PubMed, Embase and the Cochrane library databases were retrieved. Published data were extracted and analyzed by RevMan 5.3, and the results were presented as hazard ratios (HRs) [95% confidence intervals (CI)] and forest plots. RESULTS One prospective and eighteen retrospective studies were included, with a total number of 11,458 patients, 4696 of whom received postoperative chemotherapy. There was a significant improvement of the overall survival (OS) for patients who underwent operation + adjuvant chemotherapy compared to those who underwent operation alone (HR = 0.61; P < 0.001). Subgroup analyses show that the postoperative chemotherapy group compared with operation alone group are indicated as follows: hilar cholangiocarcinoma group (HR = 0.60; P < 0.001), intrahepatic cholangiocarcinoma group (HR = 0.60; P < 0.001), R1 resection group (HR = 0.71; P = 0.04), LN-positive diagnosis group (HR = 0.58; P < 0.001), gemcitabine-based chemotherapy group (HR = 0.42; P < 0.001), distal cholangiocarcinoma group (HR = 0.48; P = 0.17), R0 resection group (HR = 0.69; P = 0.43), and 5-flurouracil-based chemotherapy group (HR = 0.90; P = 0.66), respectively. CONCLUSIONS Postoperative adjuvant chemotherapy can improve the OS in intrahepatic and hilar cholangiocarcinoma patients. However, distal cholangiocarcinoma patients gain no benefit from postoperative adjuvant chemotherapy. Prospective randomized trials are warranted in order to define the standard chemotherapy regimen.

Abstract
Cholangiocarcinoma is a rare and aggressive malignancy of the biliary tract. Complete surgical resection can be curative, but the majority of patients are diagnosed with advanced disease and usually die within a year of diagnosis. Most deaths are attributable to local disease progression rather than distant metastases, supporting the use of locoregional therapies. There is evidence that locoregional therapies can provide local tumor control resulting in increased survival while avoiding some of the side effects of systemic treatments, increasing potential treatment options for patients who may be unsuitable for systemic palliative treatments. This review considers the evidence for locoregional therapies in cholangiocarcinoma, which can be classified into endoscopic, vascular, percutaneous and radiation oncological therapies. Current guidelines do not recommend the routine use of locoregional therapies due to a lack of prospective data, but the results of ongoing trials are likely to increase the evidence base and impact on clinical practice.

Abstract
BACKGROUND/AIM The role of radio(chemo) therapy for non-metastatic bile duct cancer is not well defined. This study provides additional data for this rare situation. PATIENTS AND METHODS Data of eight patients receiving radio(chemo)therapy for non-metastatic bile duct cancer were retrospectively analyzed regarding local control, metastases-free survival and overall survival. In addition to the entire cohort, five tumor- or treatment-related factors were investigated: tumor stage, histologic grading, point in time of radio(chemo)therapy, upfront surgery and concurrent chemotherapy. RESULTS Median overall survival was 37 months. Overall survival rates at 3 and 5 years were 56% and 38%, respectively. Lower histologic grading was significantly associated with better overall survival (p=0.042). Metastases-free survival rates at 3 and 5 years were 38% and 19%, while local control rates were 43% and 21%, respectively. Concurrent radiochemotherapy (vs. radiotherapy alone) resulted in significantly improved local control (p=0.014). CONCLUSION Radiochemotherapy can achieve promising results in selected patients with non-metastatic bile duct cancer.

Abstract
Purpose This study was conducted to evaluate the impact of radiation dose after margin involved resection in patients with extrahepatic bile duct cancer. Methods Among the 251 patients who underwent curative resection followed by adjuvant chemoradiotherapy, 86 patients had either invasive carcinoma (n = 63) or carcinoma in situ (n = 23) at the resected margin. Among them, 54 patients received conventional radiation dose (40-50.4 Gy) and 32 patients received escalated radiation dose (54-56 Gy). Results Escalated radiation dose was associated with improved locoregional control (5yr rate, 73.8% vs. 47.1%, p = 0.069), but not disease-free survival (5yr rate, 43.4% vs. 32.6%, p = 0.490) and overall survival (5yr rate, 40.6% vs. 29.6%, p = 0.348). In multivariate analysis for locoregional control, invasive carcinoma at the margin (HR 2.957, p = 0.032) and escalated radiation dose (HR 0.394, p = 0.047) were independent prognostic factors. No additional gastrointestinal toxicity was observed in escalated dose group. Conclusions Delivery of radiation dose ≥ 54 Gy was well tolerated and associated with improved locoregional control, but not with overall survival after margin involved resection. Further validation study is warranted.

Abstract
OBJECTIVE To evaluate the benefit of adjuvant radiotherapy (RT) after surgical resection for extrahepatic bile duct (EHBD) cancer. METHODS From 1997 to 2015, 59 patients with EHBD cancer were the subject of this study; 36 patients not undergoing adjuvant treatment after surgery (observation group) and 23 patients receiving adjuvant RT (RT group) were compared. Microscopic residual disease (R1) was in 9 (25%) patients and 5 (22%) patients, and macroscopic residual disease (R2) was in 2 (6%) patients and 6 (26%) patients in the observation and RT groups, respectively. Adjuvant RT was delivered to the tumour bed and regional lymph nodes up to 50.4 Gy (range, 45-61 Gy). RESULTS With a median follow-up of 19 months, local recurrence was observed in 10 (28%) patients and 2 (9%) patients in the observation and RT groups, respectively. On univariate analysis, the 5-year local recurrence-free survival (LRFS) rates were 50% in the observation group and 54% in the RT group (p = 0.401). The 5-year overall survival (OS) rates were 29.3% in the observation group and 26.3% in the RT group (p = 0.602). On multivariable analysis, however, adjuvant RT significantly improved LRFS [hazard ratio (HR), 0.310; 95% confidence interval (CI), 0.100-0.963; p = 0.043] and had a trend towards increased OS (HR, 0.491; 95% CI, 0.219-1.102; p = 0.085). Resection margin (RM) status was also correlated with LRFS (HR for R1 6.134, 95% CI 2.051-18.344; and HR for R2 18.551, 95% CI 3.680-93.520; p < 0.001) and OS (HR for R1 1.816, 95% CI 0.853-3.867; and HR for R2 3.564, 95% CI 1.175-10.809; p = 0.054). CONCLUSION RM status was a significant prognosticator of EHBD cancer, and adjuvant RT improved local control rate; thereby, survival rate might be increased. Advances in knowledge: The benefit of adjuvant RT in EHBD cancer was demonstrated via comparison with observation group.

Abstract
Purpose To investigate the outcomes of postoperative radiotherapy (RT), in patients with extrahepatic bile duct (EHBD) cancer by comparing the survival rate between patients undergoing surgery alone or surgery plus postoperative RT, and to identify the prognostic factors affecting survival. Materials and Methods Between 2000 and 2013, 52 patients with EHBD cancer underwent surgical resection. Of these, 33 patients did not receive postoperative RT (group I), and 19 patients did (group II). R1 resection was significantly more frequent in group II. The median radiation dose was 5,040 cGy. Results The 3-year overall survival (OS) rate for group I and group II was 38% and 56%, respectively (p = 0.274). The 3-year disease free survival (DFS) rate for group I and group II was 20% and 31%, respectively (p = 0.049), and the 3-year loco-regional recurrence free survival (LRFS) rates were 19% and 58%, respectively (p = 0.002). Multivariate analyses showed that postoperative RT and lymphovascular invasion were independent prognostic factors for DFS and LRFS. Overall, 42 patients (80%) experienced treatment failure. Distant metastasis was the predominant pattern of failure in group II. Conclusion Postoperative RT after surgical resection appeared to improve the loco-regional control and DFS rate. More effort is needed to reduce distant metastasis, the major pattern of failure, in patients who receive postoperative RT.

Abstract
Cholangiocarcinoma is a very heterogeneous and rare group of neoplasms originating from the perihilar, intra-, or extrahepatic bile duct epithelium. It represents only 3% of gastrointestinal cancers, although their incidence is increasing as its mortality increases. Surgical resection is the only potentially curative option, but unfortunately the resectability rate is low. Overall, these malignancies have got a very poor prognosis with a five-year survival rate of 5-10%. Although the five-year survival rate increases to 25-30% in the cases amenable to surgery, only 10-40% of patients present with resectable disease. Therefore, it is necessary to optimize the benefit of adjuvant strategies after surgery to increase the rate of curability. This study reviewed the role of adjuvant chemotherapy in resectable bile duct cancers.

Abstract
In the oncology landscape, cholangiocarcinoma is a challenging disease in terms of both diagnosis and treatment. Besides anamnesis and clinical examination, a definitive diagnosis of cholangiocarcinoma should be supported by imaging techniques (US, CT, MRI) and invasive investigations (ERC or EUS with brushing and FNA or US or CT-guided biopsy) followed by pathological confirmation. Surgery is the main curative option, so resectability of the tumour should be promptly assessed. Moreover, jaundice must be evaluated at the outset because biliary tract decompression with drainage and stent placement may be required. If the patient is resectable, pre-operative assessment of postoperative liver function is mandatory. After a curative resection, an adjuvant therapy may be administered. Otherwise, in cases with macroscopic residual disease after surgery or locally recurrent or unresectable cholangiocarcinoma at the diagnosis, first-line chemotherapy is the preferred strategy, possibly associated with radiotherapy and/or locoregional treatments. As the diagnostic and therapeutic pathway for cholangiocarcinoma can be declined in different modalities, patients should be promptly referred to a multidisciplinary team in a tertiary centre, familiar with this rare but lethal disease. Hence, the aim of the present paper is to focus on diagnostic and therapeutic algorithms based on the common guidelines and also on the clinical practice of multispecialist expert groups.

Abstract
Surgical treatment remains the only curative treatment for gallbladder cancer. However, even after liver resection, locoregional failure seems to be a significant problem. While there is no Level I evidence, multiple studies have shown benefit for adjuvant radiation in high-risk patients. After extensive liver resection, tolerance to conventional chemoradiation may be limited by potential liver toxicity. Stereotactic body radiotherapy has been used safely and effectively in hepatobiliary malignancies. We present a case report, highlighting the potential therapeutic role of adjuvant stereotactic body radiotherapy (SBRT) for gallbladder cancer.

Abstract
Background: Unresectable intrahepatic and hilar cholangiocarcinomas carry a dismal prognosis. Systemic chemotherapy and conventional external beam radiation and brachytherapy have been used with limited success. We explored the use of stereotactic body radiotherapy (SBRT) for these patients. Methods: Patients with unresectable intrahepatic or hilar cholangiocarcinoma or those with positive margins were included in this study. Systemic therapy was used at the discretion of the medical oncologist. The CyberknifeTM stereotactic body radiotherapy system used to treat these patients. Patients were treated with three daily fractions. Clinical and radiological follow-up were performed every three months. Results: 34 patients (16 male and 18 female) with 42 lesions were included in this study. There were 32 unresectable tumors and two patients with resected tumors with positive margins. The median SBRT dose was 30Gy in three fractions. The median follow-up was 38 months (range 8-71 months). The actuarial local control rate was 79%. The median overall survival was 17 months and the median progression free survival was ten months. There were four Grade III toxicities (12%), including duodenal ulceration, cholangitis and liver abscess. Conclusions: SBRT is an effective and reasonably safe local therapy option for unresectable intrahepatic or hilar cholangiocarcinoma.

Abstract
Purpose This study analyzed the outcomes of patients with resected extrahepatic bile duct cancer (EHBDC) in order to clarify the role of adjuvant treatments in these patients. Materials and Methods A total of 336 patients with EHBDC who underwent curative resection between 2001 and 2010 were analyzed retrospectively. The treatment types were as follows: surgery alone (n=168), surgery with chemotherapy (CTx, n=90), surgery with radiotherapy (RT) alone (n=29), and surgery with chemoradiotherapy (CRT, n=49). Results The median follow-up period was 63 months. The 5-year rates of locoregional failure-free survival (LRFFS), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) for all patients were 56.5%, 59.7%, 36.6%, and 42.0%, respectively. In multivariate analysis, surgery with RT and CRT was a significant prognostic factor for LRFFS, and surgery with CTx was a significant prognostic factor for DMFS, and surgery with CTx, RT, and CRT was a significant prognostic factor for PFS (p < 0.05). Surgery with CTx and CRT showed association with superior OS (p < 0.05), and surgery with RT had marginal significance (p=0.078). In multivariate analysis of the R1 resection patients, surgery with CRT showed significant association with OS (p < 0.05). Conclusion Adjuvant RT and CTx may be helpful in improving clinical outcomes of patients with resected EHBDC who have a high risk of disease recurrence, particularly R1 resection patients. Conduct of additional prospective, larger-scale studies will be required in order to confirm the benefit of adjuvant RT and CTx in these patients.

Abstract
AIM: To investigate the prognostic value of metastatic lymph node ratio (MLNR) in extrahepatic cholangiocarcinoma (ECC) patients undergoing radical resection.
METHODS: Seventy-eight patients with ECC were enrolled. Associations between various clinicopathologic factors and prognosis were investigated by Kaplan-Meier analyses. The Cox proportional-hazards model was used for multivariate survival analysis.
RESULTS: The overall three- and five-year survival rates were 47.26% and 23.99%, respectively. MLNR of 0, 0-0.2, 0.2-0.5, and > 0.5 corresponded to five-year survival rates of 28.59%, 21.60%, 18.84%, and 10.03%, respectively. Univariate analysis showed that degree of tumor differentiation, lymph node metastasis, MLNR, tumor-node-metastasis (TNM) stage, and margin status were closely associated with postoperative survival in ECC patients (P < 0.05). Multivariate analysis showed that MLNR and TNM stage were independent prognostic factors after pancreaticoduodenectomy (HR = 2.13, 95%CI: 1.45-3.11; P < 0.01; and HR = 1.97, 95%CI: 1.17-3.31; P = 0.01, respectively). The median survival time for MLNR > 0.5, 0.2-0.5, 0-0.2, and 0 was 15 mo, 24 mo, 23 mo, and 35.5 mo, respectively. There were statistical differences in survival time between patients with different MLNR (χ2 = 15.38; P < 0.01).
CONCLUSION: MLNR is an independent prognostic factor for ECC patients after radical resection and is useful for predicting postoperative survival.

Abstract
Cholangiocarcinomas are rare cancers arising from the epithelia of the biliary tract. The only prospect of curative therapy is with surgery. However, relapse rates are high with five-year survival rates typically around 20-30%. Involved resection margins and spread to local lymph nodes are associated with a higher risk of relapse. Such poor outcomes provide a rationale for adjuvant strategies to improve survival. However, there is little randomised data to support the use of adjuvant therapy; the available evidence base is based mostly on retrospective case series and results are often conflicting. This review evaluates the available evidence. Adjuvant therapy may be considered on an individual patient basis after discussion of the limitations of our knowledge. The results of prospective, randomised clinical trials of adjuvant therapy are eagerly awaited. Progress will require collaboration of basic science and clinical oncology and the execution of well-designed clinical trials.

Abstract
Surgical resection is the treatment of choice for bile duct cancers. The aim of this study was to investigate disease recurrence patterns and prognostic factors for recurrence of distal bile duct cancers after surgical resection. A retrospective study was performed on 122 patients with distal bile duct cancers who underwent R0 or R1 surgical resection at Korea University Guro Hospital from 1991 to 2010. Sites of initial disease recurrence were classified as locoregional or distant. Univariate and multivariate analyses were performed to investigate the factors affecting recurrence. Of the 122 patients, 80 patients developed recurrence. The disease-free survival rate was 63.1 per cent at one year and 36.4 per cent at three years. The patterns of recurrence at diagnosis were locoregional in 25 patients, locoregional and distant metastasis in 14 patients, and distant metastasis in 41 patients. Multivariate analyses revealed that recurrence pattern, lymph node metastasis, and differentiation are independent prognostic factors affecting disease-free survival. R status (marginal significance) and tumor differentiation were independent prognostic factors associated with locoregional recurrence. Differentiation and lymph node metastasis were independent prognostic factors associated with distant metastasis. The prognosis after recurrence was poor with a 1-year survival rate after recurrence of 26.1 per cent. Adjuvant chemo- or radiation therapy, delivered in patients mainly with R1 resection or with presence of lymph node metastasis, did not demonstrate the survival benefit. Significant factors for recurrence were tumor differentiation and lymph node metastasis. Therefore, close follow-up and adjuvant therapy will be necessary in patients with lymph node metastasis or poorly differentiated tumor.

Abstract
OBJECTIVES To evaluate the prognostic significance of phosphorylated Akt (p-Akt), phosphorylated mammalian target of rapamycin (p-mTOR), and total phosphatase and tensin homolog deleted on chromosome 10 (PTEN) expressions in patients undergoing adjuvant chemoradiotherapy (CRT) for proximal extrahepatic bile duct (EHBD) cancer. METHODS Sixty-three patients with proximal EHBD cancer who underwent curative resection followed by adjuvant CRT were enrolled into this study. Postoperative radiotherapy was delivered to tumor bed and regional lymph nodes up to a median of 40 Gy (range, 40 to 54 Gy). Fifty-nine patients also received fluoropyrimidine chemotherapy as a radiosensitizer. p-Akt, p-mTOR, and PTEN expression were assessed with immunohistochemical staining on the tissue microarray. RESULTS p-Akt, p-mTOR, and PTEN were expressed in 23 (36.5%), 17 (27.0%), and 24 patients (38.1%), respectively. p-Akt expression was associated with distant metastasis and overall survival (OS), but not with locoregional recurrence. The 5-year distant metastasis-free and OS rates were 25.8% versus 58.2% (P=0.007), and 27.5% versus 50.2% (P=0.0167) in patients with negative and positive expression, respectively. On multivariate analysis, nodal involvement was the only significant prognosticator predicting inferior distant metastasis-free survival (P=0.0105), whereas p-Akt expression had a borderline significance (P=0.0541). As for OS, p-Akt expression was a marginally significant prognosticator (P=0.0635), whereas other risk factors lost the statistical significance. CONCLUSION p-Akt expression tended to be associated with a favorable prognosis in patients undergoing curative resection followed by adjuvant CRT for proximal EHBD cancer.

Abstract
This study was conducted to investigate survival and prognostic factors for extrahepatic cholangiocarcinoma (ECC) following surgical resection and evaluate the effects of postoperative adjuvant therapy (AT) on overall survival (OS). We retrospectively collected clinical and pathological data between March, 2008 and December, 2013. The Kaplan-Meier method and the COX regression model were used to evaluate the OS and prognostic factors of 105 postoperative ECC patients, of whom 32 had received AT. The patients were stratified into seven risk subgroups and the survival rates were compared within each subgroup between patients who received AT and those who did not. The results demonstrated a median OS of 17.6 months, with 1- and 3-year survival rates of 67.9 and 19.5%, respectively, for the entire cohort. On univariate analysis, preoperative cholangitis, non-R0 surgical margins, poor differentiation grade, stage 3/4 and lymphatic metastasis were identified as adverse prognostic factors. AT was not significantly associated with improved OS. However, the subgroup analysis revealed that the effect of AT was significant only in the lymphatic metastasis group (median OS, 21.6 vs. 10.4 months; and 3-year OS, 16.6 vs. 0%, respectively; P=0.02). The survival curves of the AT and non-AT groups were significantly different only for node-positive patients. The COX regression model identified lymphatic metastasis, surgical margins and AT as independent prognostic factors for ECC. A negative resection margin may reduce the mortality rate following surgery by 47%. By contrast, lymph node metastasis was associated with a 2.18-fold higher mortality rate for ECC patients. Postoperative AT contributed to a 0.45-fold mortality rate compared to non-AT ECC patients. Therefore, we concluded that AT is a favorable prognostic factor for ECC patients and it may prolong the survival of patients with lymphatic metastasis. Our data suggest that postoperative AT should be recommended for node-positive ECC patients.

Abstract
Purpose Extended liver resection may provide long-term survival in selected patients with Bismuth type IV hilar cholangiocarcinoma (HCCA). The purpose of this study was to identify anatomical factors that predict curative-intended resection. Methods Thirty-three of 159 patients with Bismuth type IV HCCA underwent major hepato-biliary resection with curative intent (CIR) between 2000 and 2010. Disease extent and anatomical variations were analyzed as factors enabling CIR. Results CIR ratio with hilar trifurcation bile duct variation (13/16) was significantly higher than that with other bile duct variation types (18/25). Hilum to left second bile duct confluence and tumor infiltration over left second bile duct confluence lengths in right-sided CIR were significantly shorter than those lengths in left-sided CIR (10.8 ± 4.9 and 2.7 ± 0.8 mm vs. 16.5 ± 8.4 and 7.0 ± 5.3 mm, respectively). Left-sided CIR patients had a marginally higher proportion of tumors invading ≤5 mm over the right second confluence than that in right-sided CIR patients (13/17 vs. 6/16; P = 0.061). The 3-year survival rate after CIR (28%) was significantly higher than after non-CIR (6.1%). Conclusion We recommend the criteria of CIR as bile duct variation type, length of hilum to contralateral second bile duct confluence, and extent of tumor infiltration over the second confluence for Bismuth type IV HCCA.

Abstract
BACKGROUND The fate of a microscopic positive ductal margin (MPDM) of extrahepatic bile duct (EHBD) cancer is unclear. The purpose of this study was to analyse the clinicopathological features of EHBD cancer with MPDM and to identify the prognostic factors associated with survival. METHODS Between 1995 and 2007, a retrospective analysis of 464 patients who had undergone surgical resection for EHBD cancer was conducted. Clinicopathological factors likely to influence survival were assessed using univariate and multivariate analysis. RESULTS One hundred twenty-four patients had MPDM which included invasive carcinoma (IC) (n =85) and carcinoma in situ (CIS)/ high-grade dysplasia (HGD) (n = 39). The median survival (MS) of R0, R1 as CIS/ HGD, and R1 as IC were 41 months, 29 months, and 18 months, respectively. Adverse prognostic factors were 'IC' on the resection margin [HR = 1.66, 95% confidence intervals (CIs) 1.06-2.59, P = 0.026], and no use of adjuvant chemoradiotherapy (HR = 1.57, 95% CIs 1.04-2.39, P = 0.033). Adjuvant chemoradiotherapy was beneficial in patients with MPDM as IC (5-year survival rate 19.7 compared with 2.8%, P = 0.011). CONCLUSIONS The presence of MPDM is an important prognostic factor in EHBD cancer. When a ductal resection margin is positive, discrimination between 'IC' and 'CIS/ HGD' is important.

Abstract
PURPOSE To find the applicability of adjuvant radiotherapy for extrahepatic bile duct cancer (EBDC), we analyzed the pattern of failure and evaluate prognostic factors of locoregional failure after curative resection without adjuvant treatment. MATERIALS AND METHODS In 97 patients with resected EBDC, the location of tumor was classified as proximal (n = 26) and distal (n = 71), using the junction of the cystic duct and common hepatic duct as the dividing point. Locoregional failure sites were categorized as follows: the hepatoduodenal ligament and tumor bed, the celiac artery and superior mesenteric artery, and other sites. RESULTS The median follow-up time was 29 months for surviving patients. Three-year locoregional progression-free survival, progression-free survival, and overall survival rates were 50%, 42%, and 52%, respectively. Regarding initial failures, 79% and 81% were locoregional failures in proximal and distal EBDC patients, respectively. The most common site was the hepatoduodenal ligament and tumor bed. In the multivariate analysis, perineural invasion was associated with poor locoregional progression-free survival (p = 0.023) and progression-free survival (p = 0.012); and elevated postoperative CA19-9 (≥37 U/mL) did with poor locoregional progression-free survival (p = 0.002), progression-free survival (p < 0.001) and overall survival (p < 0.001). CONCLUSION Both proximal and distal EBDC showed remarkable proportion of locoregional failure. Perineural invasion and elevated postoperative CA19-9 were risk factors of locoregional failure. In these patients with high risk of locoregional failure, adjuvant radiotherapy could be considered to improve locoregional control.

Radiat Oncol J 2014; 32:7-13. [PMID: 24724046 PMCID: PMC3977131 DOI: 10.3857/roj.2014.32.1.7] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2013] [Revised: 01/13/2014] [Accepted: 02/13/2014] [Indexed: 12/21/2022] Open
Abstract
Purpose To evaluate the results of postoperative radiotherapy in patients with extra-hepatic bile duct cancer (EHBDC) and identify the prognostic factors for local control and survival. Materials and Methods Between January 2001 and December 2010, we retrospectively reviewed the cases of 70 patients with EHBDC who had undergone curative resection and received postoperative radiotherapy. The median radiation dose was 50.4 Gy (range, 41.4 to 54 Gy). The resection margin status was R0 in 30 patients (42.9%), R1 in 25 patients (35.7%), and R2 in 15 patients (21.4%). Results The 5-year rates of overall survival (OS), event-free survival (EFS), and locoregional control (LRC) for all patients were 42.9%, 38.3%, and 61.2%, respectively. The major pattern of failure was distant relapses (33 patients, 47.1%). A multivariate analysis showed that the postradiotherapy CA19-9 level, radiation dose (≥50 Gy), R2 resection margins, perineural invasion, and T stage were the significant prognostic factors for OS, EFS, and LRC. OS was not significantly different between the patients receiving R0 and R1 resections, but was significantly lower among those receiving R2 resection (54.6%, 56.1%, and 7.1% for R0, R1, and R2 resections, respectively). Conclusion In patients with EHBDC who had undergone curative resection, a postoperative radiotherapy dose less than 50 Gy was suboptimal for OS and LRC. Higher radiation doses may be needed to obtain better LRC. Further investigation of novel therapy or palliative treatment should be considered for patients receiving R2 resection.

Abstract
BACKGROUNDS/AIMS Little is known about clinical features and survival outcome in locally advanced unresectable extrahepatic cholangiocarcinoma (EHC). The aim was to investigate the clinical features and the survival outcome in these patients, and to evaluate the role of palliative resections in locally advanced unresectable EHC. METHODS Between 1995 and 2007, 280 patients with locally advanced unresectable EHC were identified. Clinical, pathologic, and survival data were investigated. A comparative analysis was done between those who received palliative resection (PR) and those who were not operated on (NR). RESULTS The overall median survival of the study population was 10±1 months, and the 3- and 5-year survival rates (YSR) were 8.5% and 2.5%, respectively. The median survival, 3- and 5-YSR of PR were 23 months, 32.1% and 13.1%, respectively. For NR, they were 9 months, 3.9% and 0%, which were significantly worse than PR (p<0.001). In univariate analysis, T classification, N classification, tumor location, palliative resection, adjuvant treatment, chemotherapy, and radiation therapy were factors that showed survival difference between PR and NR. Regional lymph node metastasis (RR, 2.084; 95% CI, 1.491-2.914; p<0.001), non-resections (RR, 2.270; 95% CI, 1.497-3.443; p<0.001), and no chemotherapy (RR, 1.604; 95% CI, 1.095-2.349; p=0.015) were identified as risk factors for poor outcome on multivariate analysis. CONCLUSIONS Without evidence of systemic disease, palliative resection may provide some survival benefit in selected locally advanced unresectable EHCs and adjuvant treatment may further improve survival outcome.

Abstract
Hepatocellular carcinoma (HCC) is the third most common cause of cancer worldwide and is rising in incidence. Ultrasound is the preferred modality for screening high-risk patients for HCC because it detects clinically significant nodules, widespread availability and lower cost. HCC does not require a biopsy for diagnosis if specific imaging criteria are fulfilled. Transarterial chemoembolization (TACE) is the most common modality used to treat HCC followed by ablation. Cholangiocarcinoma (CCA) is increasing in incidence and the second most common primary malignancy of the liver. There is no effective screening strategy for CCA although magnetic resonance imaging and carbohydrate antigen 19-9 (CA 19-9) are commonly used without proven benefit. Therapy for CCA is challenging and resection, when possible, is the mainstay of therapy. Gemcitabine in combination with cisplatin or biologics may offer a modest survival benefit. Liver transplantation for CCA is associated with reasonable survival in select cases. Molecular diagnostics offer the potential to develop personalized approaches in the management of HCC and CCA.

Abstract
Cholangiocarcinoma (CC) is a rare cancer arising from the epithelium of the biliary tree, anywhere from the small peripheral hepatic ducts to the distal common bile duct. Classification systems for CC typically group tumours by anatomical location into intrahepatic, hilar or extrahepatic subtypes. Surgical resection or liver transplantation remains the only curative therapy for CC, but up to 80% of patients present with advanced, irresectable disease. Unresectable CC remains resistant to many chemotherapeutic agents, although gemcitabine, particularly in combination with other agents, has been shown to improve overall survival. Ongoing investigation of biological agents has also yielded some promising results. Several novel interventional and endoscopic techniques for the diagnosis and management of non-operable CC have been developed: initial results show improvements in symptoms and progression-free survival, but further randomised studies are required to establish their role in the management of CC.

Abstract
Cholangiocarcinoma (CCA) is the second most common primary hepatic malignancy worldwide. The incidence of intrahepatic CCA is increasing, whereas that of extrahepatic CCA is decreasing. This review looks at the new advances that have been made in the management of CCA, based on a PubMed and Science Citation Index search of results from randomized controlled trials, reviews, and cohort, prospective and retrospective studies. Aggressive interventional approaches and new histopathological techniques have been developed to make a histological diagnosis in patients with high risk factors or suspected CCA. Resectability of the tumour can now be assessed using multiple radiological imaging studies; the main prognostic factor after surgery is a histologically negative resection margin. Biliary drainage and/or portal vein embolization may be performed before extended radical resection, or liver transplantation may be undertaken in combination with neoadjuvant chemotherapy or chemoradiotherapy. Though many advances have been made in the management of CCA, the standard modality of treatment has not yet been established. This review focuses on the clinical options for different stages of CCA.

Abstract
PURPOSE To develop nomograms for predicting the overall survival (OS) and relapse-free survival (RFS) in patients with extrahepatic bile duct cancer undergoing adjuvant chemoradiation therapy after curative resection. METHODS AND MATERIALS From January 1995 through August 2006, a total of 166 consecutive patients underwent curative resection followed by adjuvant chemoradiation therapy. Multivariate analysis using Cox proportional hazards regression was performed, and this Cox model was used as the basis for the nomograms of OS and RFS. We calculated concordance indices of the constructed nomograms and American Joint Committee on Cancer (AJCC) staging system. RESULTS The OS rate at 2 years and 5 years was 60.8% and 42.5%, respectively, and the RFS rate at 2 years and 5 years was 52.5% and 38.2%, respectively. The model containing age, sex, tumor location, histologic differentiation, perineural invasion, and lymph node involvement was selected for nomograms. The bootstrap-corrected concordance index of the nomogram for OS and RFS was 0.63 and 0.62, respectively, and that of AJCC staging for OS and RFS was 0.50 and 0.52, respectively. CONCLUSIONS We developed nomograms that predicted survival and recurrence better than AJCC staging. With caution, clinicians may use these nomograms as an adjunct to or substitute for AJCC staging for predicting an individual's prognosis and offering tailored adjuvant therapy.

Abstract
AIM: To evaluate the prognostic significance of CD24 expression in patients undergoing adjuvant chemoradiotherapy for extrahepatic bile duct (EHBD) cancer.
METHODS: Eighty-four patients with EHBD cancer who underwent curative resection followed by adjuvant chemoradiotherapy were enrolled in this study. Postoperative radiotherapy was delivered to the tumor bed and regional lymph nodes up to a median of 40 Gy (range: 40-56 Gy). All patients also received fluoropyrimidine chemotherapy for radiosensitization during radiotherapy. CD24 expression was assessed with immunohistochemical staining on tissue microarray. Clinicopathologic factors as well as CD24 expression were evaluated in multivariate analysis for clinical outcomes including loco-regional recurrence, distant metastasis-free and overall survival.
RESULTS: CD24 was expressed in 36 patients (42.9%). CD24 expression was associated with distant metastasis, but not with loco-regional recurrence nor with overall survival. The 5-year distant metastasis-free survival rates were 55.1% and 29.0% in patients with negative and positive expression, respectively (P = 0.0100). On multivariate analysis incorporating N stage, histologic differentiation and CD24 expression, N stage was the only significant factor predicting distant metastasis-free survival (P = 0.0089), while CD24 expression had borderline significance (P = 0.0733). In subgroup analysis, CD24 expression was significantly associated with 5-year distant metastasis-free survival in node-positive patients (38.4% with negative expression vs 0% with positive expression, P = 0.0110), but not in node-negative patients (62.0% with negative expression vs 64.0% with positive expression, P = 0.8599).
CONCLUSION: CD24 expression was a significant predictor of distant metastasis for patients undergoing curative resection followed by adjuvant chemoradiotherapy especially for node-positive EHBD cancer.

Abstract
Biliary tract cancer is a rare malignant tumor. There is limited knowledge about biology and natural history of this disease and considerable uncertainty remains regarding its optimal diagnostic and therapeutic management. The role of adjuvant therapy is object of debate and controversy. Although resection is identified as the most effective and the only potentially curative treatment, there is no consensus on the impact of adjuvant chemotherapy and/or radiotherapy on the high incidence of disease recurrence and on survival. This is mainly due to the rarity of this disease and the consequent difficulty in performing randomized trials. The only two prospectively controlled trials concluded that adjuvant chemotherapy did not improve survival. Most of the retrospective trials, which had limited sample size and included heterogeneous patients population and non-standardized therapies, suggested a marginal benefit of chemoradiotherapy in reducing locoregional recurrence and an uncertain impact on survival. Well-designed multi-institutional randomized trials are necessary to clarify the role of adjuvant therapy. Two ongoing phase III trials may provide relevant information.

Abstract
OBJECTIVE The objective of our study was to retrospectively evaluate local control and survival after radiofrequency ablation (RFA) in patients with liver metastases arising from extrahepatic cholangiocarcinoma who had previously undergone curative resection. MATERIALS AND METHODS From May 2003 to May 2009, RFA using an internally cooled electrode was performed on 29 metachronous liver metastases (mean number of tumors per patient, 1.6) arising from extrahepatic cholangiocarcinoma in 18 patients (mean age, 66 years). Tumor size ranged from 0.9 to 4.6 cm in maximum dimension (mean, 2.3 cm). As historical comparisons, we included 24 patients diagnosed with recurrent metastasis limited to the liver between February 1997 and April 2003 and who met the inclusion criteria for RFA: 16 patients received supportive therapy only and eight patients underwent chemotherapy with or without radiation. RESULTS Five patients had major complications (liver abscess, n = 4 patients; biliary stricture, n = 1; 17% per-treatment complication rate [5/29]), but there were no procedure-related deaths. Complete tumor necrosis was achieved in all 29 tumors after one session of RFA. The local tumor progression rate was 38% (median time to detection, 5 months). From the first diagnosis of liver metastasis, the median overall survival was 12.4 months and the 3-year survival rate was 10%. Patients who received RFA lived significantly longer than patients who received chemoradiotherapy (median survival, 5.6 months) and those who received supportive treatment (median survival, 5.3 months) (p < 0.001). CONCLUSION Percutaneous RFA results in effective local tumor control and may prolong survival in patients with recurrent hepatic metastases after curative resection for extrahepatic cholangiocarcinoma.

Abstract
BACKGROUND The majority of patients with cholangiocarcinoma present with advanced, irresectable tumours associated with poor prognosis. The incidence and mortality rates associated with cholangiocarcinoma continue to rise, mandating the development of novel strategies for early detection, improved resection and treatment of residual lesions. AIM To review the current evidence base for surgical, adjuvant and neo-adjuvant techniques in the management of cholangiocarcinoma. METHODS A search strategy incorporating PubMed/Medline search engines and utilising the key words biliary tract carcinoma; cholangiocarcinoma; management; surgery; chemotherapy; radiotherapy; photodynamic therapy; and radiofrequency ablation, in various combinations, was employed. RESULTS Data on neo-adjuvant and adjuvant techniques remain limited, and much of the literature concerns palliation of inoperable disease. The only opportunity for long-term survival remains surgical resection with negative pathological margins or liver transplantation, both of which remain possible in only a minority of selected patients. Neo-adjuvant and adjuvant techniques currently provide only limited success in improving survival. CONCLUSIONS The development of novel strategies and treatment techniques is crucial. However, the shortage of randomised controlled trials is compounded by the low feasibility of conducting adequately powered trials in liver surgery, due to the large sample sizes that are required.
