World J Gastroenterol 2013; 19:1438-1443. [PMID: 23539485 PMCID: PMC3602503 DOI: 10.3748/wjg.v19.i9.1438] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2012] [Revised: 12/26/2012] [Accepted: 01/07/2013] [Indexed: 02/06/2023] Open
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
BACKGROUND/PURPOSE The aims of this study were to evaluate long-term outcomes and to determine prognostic factors for survival in patients with resected biliary carcinoma who received adjuvant gemcitabine plus S-1 chemotherapy. METHODS Seventy patients with International Union Against Cancer (UICC) stage II, III, or IV biliary carcinoma received postoperative adjuvant chemotherapy consisting of intravenous gemcitabine 700 mg/m(2) on day 1 and oral S-1 60-100 mg/body for seven consecutive days, followed by a 1-week pause of chemotherapy. Patients received up to ten 2-week cycles. Long-term outcomes and predictors of survival with this adjuvant chemotherapy regimen were analyzed. RESULTS The median duration of follow-up was 47 months. Fifty-six percent of patients had node-positive disease, and 80% of patients underwent R0 resection. Overall and disease-free survival rates were 91 and 81% at 1 year, 56 and 55% at 3 years, and 40 and 46% at 5 years, respectively. Lymph node status (p = 0.025) and surgical margin status (p = 0.033) were independently associated with long-term survival by multivariate analysis. CONCLUSIONS Adjuvant gemcitabine plus S-1 chemotherapy may be a promising strategy for patients with resected biliary carcinoma, and nodal status and surgical margin status may be predictors of survival with this treatment strategy.

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
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
BACKGROUND Extrahepatic biliary duct cancers (EBDC) are uncommon malignancies characterized by a poor prognosis with high rate of loco-regional recurrence. The purpose of the present study is to assess the feasibility and the potential impact of adjuvant radiotherapy (RT) in a series of patients treated in one institution. METHODS Twenty three patients with non-metastatic bile duct cancer treated surgically with curative intent (4 gallbladder, 7 ampullary and 12 cholangiocarcinoma) received 3D conformal external beam RT to a median total dose of 50.4 Gy. Concurrent chemotherapy based on 5-FU was delivered to 21 patients (91%). Surgical margins were negative in 11 patients (48%), narrow in 2 (9%), and microscopically involved in 8 (35%). Eleven patients (55%) had metastatic nodal involvement. The average follow-up time for all patients was 30 months (ranging from 3-98). RESULTS Acute gastrointestinal grade 2 toxicity (RTOG scale) was recorded in 2 patients (9%). Nausea or vomiting grade 1 and 2 was observed in 8 (35%) and 2 patients (9%) respectively. Only one patient developed a major late radiation-induced toxicity. The main pattern of recurrence was both loco-regional and distant (liver, peritoneum and/or lung). No difference was observed in loco-regional control according to the tumor location. The 5-year actuarial loco-regional control rate was 48.3% (67% and 30% for patients operated on with negative and positive/narrow/unknown margins respectively, p=0.04). The 5-year actuarial overall survival was of 35.9% for the entire group (61.4% in case of negative margins and 16.7% in case of positive/narrow/unknown margins, p=0.07). CONCLUSIONS Postoperative RT with 50-60 Gy is feasible with acceptable acute and late toxicities. The potential benefit observed in our series may support the use of adjuvant RT in patients with locally advanced disease. Prospective randomized trials are warranted to confirm definitively the role of RT in this tumor location.

A systematic review with a meta-analysis of observational studies. Cancer Treat Rev 2011; 38:111-9.

Abstract
BACKGROUND The role for adjuvant radiotherapy (ART) after curative resection in extrahepatic cholangiocarcinoma remains unclear. Due to the lack of randomized trials, available data comes from single center experiences or data-based population studies with inconclusive results. OBJECTIVE To assess the impact of radiotherapy (with or without concurrent chemotherapy) on toxicity and survival of radically resected patients with extrahepatic bile duct cancer (extrahepatic cholangiocarcinoma, gallbladder cancer and pure ampullary cancer). DATA SOURCES AND STUDY SELECTION Eligible studies with data on survival, recurrence and toxicity were retrieved from the MEDLINE, ISI web of science, EMBASE and Cochrane databases from January 1995 to December 2008, to ensure that all ART treatments were performed with conventional 3D techniques. In the absence of randomized controlled-studies, all observational cohort studies (longitudinal and historical) were initially considered. Ten retrospective cohort studies (where the use of concurrent CT was reported only in 2), met all inclusion criteria and were enrolled for final meta-analysis. Hazard ratio (HR) had to be extracted from survival curves using the Tierney et al. methods. MIX 1.7 statistical software was used for meta-analysis. RESULTS All studies on ART used conventional 3D-techniques. Patients in the ART cohorts were more likely to have involved surgical margins and positive lymph nodes. For extrahepatic cholangiocarcinoma location, ART significantly improved overall survival (HR 0.62; 95% CI 0.48 to 0.78, p<0.001). Meta-analysis was not feasible for gallbladder cancer and ampullary cancer locations. Late radiation-induced toxicity was low (2-9% late obstruction or GI bleeding). CONCLUSION In the absence of randomized controlled studies, we found in the present systematic review and meta-analysis of observational studies that, patients with extrahepatic cholangiocarcinoma treated with adjuvant RT have a significant lower risk of dying compared to patients treated with surgery alone.

Abstract
The aim of this review is to describe recent advances and topics in the surgical management of bile duct cancer. Radical resection with a microscopically negative margin (R0) is the only way to cure cholangiocarcinoma and is associated with marked survival advantages compared to margin-positive resections. Complete resection of the tumor is the surgeon’s ultimate aim, and several advances in the surgical treatment for bile duct cancer have been made within the last two decades. Multidetector row computed tomography has emerged as an indispensable diagnostic modality for the precise preoperative evaluation of bile duct cancer, in terms of both longitudinal and vertical tumor invasion. Many meticulous operative procedures have been established, especially extended hepatectomy for hilar cholangiocarcinoma, to achieve a negative resection margin, which is the only prognostic factor under the control of the surgeon. A complete caudate lobectomy and resection of the inferior part of Couinaud’s segment IV coupled with right or left hemihepatectomy has become the standard surgical procedure for hilar cholangiocarcinoma, and pylorus-preserving pancreaticoduodenectomy is the first choice for distal bile duct cancer. Limited resection for middle bile duct cancer is indicated for only strictly selected cases. Preoperative treatments including biliary drainage and portal vein embolization are also indicated for only selected patients, especially jaundiced patients anticipating major hepatectomy. Liver transplantation seems ideal for complete resection of bile duct cancer, but the high recurrence rate and decreased patient survival after liver transplant preclude it from being considered standard treatment. Adjuvant chemotherapy and radiotherapy have a potentially crucial role in prolonging survival and controlling local recurrence, but no definite regimen has been established to date. Further evidence is needed to fully define the role of liver transplantation and adjuvant chemo-radiotherapy.

Abstract
PURPOSE The benefit of adjuvant radiotherapy (RT) after surgical resection for extrahepatic cholangiocarcinoma has not been clearly established. We analyzed survival outcomes of patients with resected extrahepatic cholangiocarcinoma and examined the effect of adjuvant RT. METHODS AND MATERIALS Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) program between 1973 and 2003. The primary endpoint was the overall survival time. Cox regression analysis was used to perform univariate and multivariate analyses of the following clinical variables: age, year of diagnosis, histologic grade, localized (Stage T1-T2) vs. regional (Stage T3 or greater and/or node positive) stage, gender, race, and the use of adjuvant RT after surgical resection. RESULTS The records for 2,332 patients were obtained. Patients with previous malignancy, distant disease, incomplete or conflicting records, atypical histologic features, and those treated with preoperative/intraoperative RT were excluded. Of the remaining 1,491 patients eligible for analysis, 473 (32%) had undergone adjuvant RT. After a median follow-up of 27 months (among surviving patients), the median overall survival time for the entire cohort was 20 months. Patients with localized and regional disease had a median survival time of 33 and 18 months, respectively (p<.001). The addition of adjuvant RT was not associated with an improvement in overall or cause-specific survival for patients with local or regional disease. CONCLUSION Patients with localized disease had significantly better overall survival than those with regional disease. Adjuvant RT was not associated with an improvement in long-term overall survival in patients with resected extrahepatic bile duct cancer. Key data, including margin status and the use of combined chemotherapy, was not available through the SEER database.

Abstract
Abstract
Background
Although ductal resection margin status in extrahepatic cholangiocarcinoma is evaluated by intraoperative histological examination of frozen sections, its clinical relevance remains controversial.
Methods
Material taken from patients who underwent R0 or R1 resection for extrahepatic cholangiocarcinoma with intraoperative histological examination of the final ductal resection margins between 1994 and 2003 were reviewed. The following histological classification was used: insufficient, negative for malignancy (NM), undetermined lesion (UDL) or positive for malignancy (PM). Multivariable analyses of overall survival and anastomotic recurrence in relation to ductal margin status were performed.
Results
Resection material from 363 patients was identified. For the proximal ductal margin, only PM in intramural lesions was significantly associated with poor survival (hazard ratio (HR) 1·72, 95 per cent confidence interval (c.i.) 1·06 to 2·74) and anastomotic recurrence (HR 6·39, 95 per cent c.i. 1·89 to 21·62) compared with NM. In analysis of overall survival according to distal ductal margin status, the HRs for UDL and PM lesions in comparison with NM were not significant.
Conclusion
PM in intramural lesions found during intraoperative histological examination of the proximal ductal resection margin was related to clinical outcome. This finding favours additional resection of the bile duct. A similar association was not found for histology results of the distal resection margin.

Abstract
PURPOSE To evaluate the effect of postoperative concurrent chemoradiotherapy using three-dimensional conformal radiotherapy and to identify the prognostic factors that influence survival in patients with extrahepatic bile duct cancer. METHODS AND MATERIALS We retrospectively analyzed the data from 101 patients with extrahepatic bile duct cancer who had undergone postoperative concurrent chemoradiotherapy using three-dimensional conformal radiotherapy. Of the 101 patients, 52 (51%) had undergone complete resection (R0 resection) and 49 (49%) had microscopic or macroscopic residual tumors (R1 or R2 resection). The median radiation dose was 50 Gy. Also, 85 patients (84%) underwent concurrent chemotherapy with 5-fluorouracil. RESULTS The median follow-up period was 47 months for the surviving patients. The 5-year overall survival rate was 34% for all patients. A comparison between patients with R0 and R1 resection indicated no significant difference in the 5-year overall survival (44% vs. 33%, p=.2779), progression-free survival (35% vs. 22%, p=.3107), or locoregional progression-free survival (75% vs. 63%, p=.2784) rates. An analysis of the first failure site in the 89 patients with R0 or R1 resection indicated isolated locoregional recurrence in 7 patients. Elevated postoperative carbohydrate antigen 19-9 level was an independent prognostic factor for overall survival (p=.001) and progression-free survival (p=.033). A total of 3 patients developed Grade 3 or greater late toxicity. CONCLUSION Adjuvant concurrent chemoradiotherapy using three-dimensional conformal radiotherapy appears to improve locoregional control and survival in extrahepatic bile duct cancer patients with R1 resection. The postoperative carbohydrate antigen 19-9 level might be a useful prognostic marker to select patients for more intensified adjuvant therapy.

Abstract
In patients with hilar cholangiocarcinoma, extended hepatectomy and caudate lobe resection are often performed to achieve an R0 resection. In patients whose standardized future liver remnant is less than or equal to 20% of total liver volume, portal vein embolization (PVE) should be performed. In patients with biliary dilatation of the future liver remnant, a biliary drainage catheter should be placed before PVE. If the planned surgery is an extended right hepatectomy, segment 4 branch embolization improves the hypertrophy of segments 2 and 3. In high-volume centers, PVE can be safely performed; it increases the resectability rate and results in the same survival rates as those in patients who undergo resection without PVE.
