Advanced biliary tract carcinomas: a retrospective multicenter analysis of first and second-line chemotherapy

FOLFIRI-bevacizumab as a second-line treatment for advanced biliary tract cancer after gemcitabine-based chemotherapy

Background

Advanced biliary tract cancer (BTC) has a poor prognosis. Gemcitabine with platinum chemotherapy was the standard first-line chemotherapeutic regimen until the recent addition of anti-PD-1/PD-L1 antibodies. After disease progression, the only second-line chemotherapy that has demonstrated a survival benefit versus supportive care is FOLFOX (folinic acid, fluorouracil, and oxaliplatin), with a modest benefit. This study aimed to assess the efficacy and safety of second-line FOLFIRI (folinic acid, fluorouracil, and irinotecan) combined with bevacizumab for advanced BTC.

Methods

This single-center retrospective study enrolled patients with metastatic BTC (intrahepatic cholangiocarcinoma [ICC], extrahepatic cholangiocarcinoma [ECC], or gallbladder carcinoma) that progressed after first-line gemcitabine-based chemotherapy. FOLFIRI-bevacizumab was administered intravenously every 2 weeks [folinic acid 200 mg/m², fluorouracil 400 mg/m² (bolus), fluorouracil 2400 mg/m² (46-h continuous intravenous infusion), irinotecan 180 mg/m², and bevacizumab 5 mg/kg] until unacceptable toxicity, patient refusal, or disease progression.

Results

Overall, 28 patients received the FOLFIRI-bevacizumab regimen after gemcitabine-based chemotherapy. The median overall survival (OS) was 9.0 months (95% CI 6.4-16.5). The OS rate was 39.3% (95% CI 24.8-62.3) and 10.7% (95% CI 3.7-32.1) at 12- and 24-months respectively. The median progression-free survival (PFS) was 5.2 months (95% CI 3.1-10.2) with FOLFIRI-bevacizumab. The PFS rates at 12 months and 24 months were 17.9% (95% CI 8.19-39.5] and 10.7% (95% CI 3.7-31.2), respectively. The overall response rate (ORR) to FOLFIRI-bevacizumab was 23.1%, with a disease control rate (DCR) of 69.3%. Grade 3-4 adverse events (sAE) were reported in 20 patients (71.4%) treated with FOLFIRI-bevacizumab.

Conclusion

FOLFIRI-bevacizumab as a second-line treatment for advanced BTC after gemcitabine-based chemotherapy showed efficacy and safety with a promising tumor response rate in this retrospective single-center study.

A Systematised Literature Review of Real-World Treatment Patterns and Outcomes in Unresectable Advanced or Metastatic Biliary Tract Cancer

BACKGROUND

Biliary tract cancers are rare aggressive malignancies typically diagnosed when the disease is metastatic or unresectable, precluding curative treatment.

OBJECTIVE

We aimed to identify treatment guidelines, real-world treatment patterns, and outcomes for unresectable advanced or metastatic biliary tract cancers in adult patients.

METHODS

Databases (MEDLINE, Embase, Cochrane Database of Systematic Reviews) were systematically searched between 1 January, 2000 and 25 November, 2021, and supplemented by hand searches. Eligible records were (1) treatment guidelines and (2) observational studies reporting real-world treatment outcomes, for unresectable advanced or metastatic biliary tract cancers. Only studies performed in the UK, Germany, France, Australia, Canada and South Korea were extracted, to moderate the number of records for synthesis while maintaining representation of a wide range of biliary tract cancer incidences.

RESULTS

A total of 66 relevant unique full-text records were extracted, including 16 treatment guidelines and 50 observational studies. Among guidelines, chemotherapies were most strongly recommended at first line (1L); the combination of gemcitabine and cisplatin (GEMCIS) was recommended as the standard of care in 1L. Recommendations for systemic chemotherapy in the second line (2L) conflicted because of uncertainties around survival benefit. Guidelines on further lines of treatment included a range of locoregional modalities and stenting or best supportive care without providing clear recommendations because of data paucity. Fifty observational studies reporting real-world treatment outcomes were extracted, of which 25 (50%) and 9 (18%) reported outcomes in 1L and 2L, respectively; 22 (44%) reported outcomes for treatments described as 'palliative'. In 1L, outcomes for systemic chemotherapy were most frequently described (23/25 studies), and GEMCIS was the most common systemic chemotherapy used (10/23 studies) in line with guidelines. Median overall survival with 1L systemic chemotherapy was < 12 months in most studies (16/23; range 4.7-22.3 months). Most 2L studies (10/11) described outcomes for systemic chemotherapy, most commonly for fluoropyrimidine-based regimen (5/10 studies). Median overall survival with 2L systemic chemotherapy was < 12 months in 5/10 studies (range 4.9-21.5 months). Median progression-free survival was reported more rarely than median overall survival. Some studies with small sample sizes or specifically selected patient populations (e.g. higher performance status, or patients who had already responded to treatment) achieved higher median overall survival.

CONCLUSIONS

At the time of this review, treatment options for unresectable advanced or metastatic biliary tract cancers confer poor real-world survival. For over a decade, GEMCIS remained the 1L standard of care, highlighting the lack of therapeutic innovation in this indication and the urgent unmet need for novel treatments with improved outcomes in this aggressive condition. Additional observational studies are needed to further understand the effectiveness of currently available treatments, as well as newly available therapies including the addition of immunotherapy in the evolving treatment landscape.

Laparoscopic hepatopancreaticoduodenectomy for synchronous gallbladder cancer and extrahepatic cholangiocarcinoma: a case report

Background

Hepatopancreaticoduodenectomy (HPD) is one of the most complex procedures, and it is very rarely reported. Laparoscopic HPD (LHPD) is even rarer. To date, there are only 3 reports of LHPD for locally advanced gallbladder cancer (GBC) or extrahepatic cholangiocarcinoma (ECC). This is the first report of LHPD for synchronous GBC and ECC.

Case presentation

A 75-year-old female patient complained of jaundice for 2 weeks without fever or abdominal pain. She was diagnosed with synchronous GBC and ECC. After a comprehensive preparation, she underwent a laparoscopic pancreaticoduodenectomy and resection of hepatic segments of IVb and V, and her digestive tract reconstruction followed Child’s methods. She was discharged on the 12th day postoperatively without pancreatic leakage, biliary leakage, or liver failure.

Conclusions

LHPD is safe and feasible for selected cases of GBCs or ECCs.

Second-line treatments in advanced biliary tract cancer: systematic literature review of efficacy, effectiveness and safety

Background: A systematic review was conducted to understand clinical, economic and health-related quality-of-life outcomes in second-line biliary tract cancer. Materials & methods: The review followed established recommendations. The feasibility of network meta-analysis revealed limited networks, thus synthesis was limited to a summary of reported ranges, percentiles and medians. Results: The review included 62 trials and observational studies highly variable with respect to key baseline characteristics. Commonly evaluated second-line treatments included fluoropyrimidine-, gemcitabine- and S-1-based regimens. Across active treatment arms, median overall survival ranged from 3.5 to 15.0 months (median: 6.9), median progression-free survival from 1.4 to 6.5 months (median: 2.9) and objective response from 0 to 36.4%. Outcomes were similar between study types, with a few notable outliers. Treatment-related/-emergent adverse events were infrequently reported; no studies reported economic or health-related quality-of-life outcomes. Conclusions: Biliary tract cancer is a difficult-to-treat disease with poor prognosis. Despite evolving treatment landscapes, more recent studies did not show clinical outcome improvement, highlighting an unmet need among advanced/metastatic patients.

Efficacy and Safety of FOLFOX as a Second-Line Chemotherapy for Patients with Locally Advanced and/or Metastatic Carcinoma Gall Bladder – Experience from a Tertiary Care Center in India

Background: Carcinoma gallbladder is mostly diagnosed in locally advanced, inoperable, or metastatic stage. Best supportive care with or without palliative chemotherapy is the only feasible treatment option. Gemcitabine and platinum agents' combination is the most effective first option with no well-established second-line regimen. Objectives: We planned to study the response rate, safety, the progression-free survival (PFS), and overall survival (OS) on the second-line FOLFOX-4 chemotherapy. Methods: This is a prospective single-arm observational study of 29 eligible patients. Patients were studies for response to the second-line FOLFOX-4 chemotherapy. Positron emission tomography/computed tomography scans were done for response assessment; chemotherapy toxicity was graded using National Cancer Institute clinical toxicity criteria; and survival rates (PFS and OS) were studied. Results: Among the 39 patients with gemcitabine-based chemotherapy (CT-1), the median PFS-1 was 6.5 months. Twenty-nine patients received second-line chemotherapy (CT-2). Responses observed complete response in 2/29, partial response in 7/29, stable disease in 1/29 patients, and progressive disease in 19/29. The overall response rate was 9/29 (31.0%). Grades 2–4 toxicities were anemia (17.95%), thrombocytopenia (12.82%), neutropenia (12.82%), and peripheral neuropathy (7.69%). The median OS was 9.13 months. Late PFS-1 (>median PFS-1) patients had significantly lower mortality as compared to early PFS-1, odds ratio of 0.251 (P = 0.002), and median PFS-2 was 2.53 months. Conclusion: After the failure of gemcitabine and platinum-based chemotherapy, FOLFOX-4 is modestly effective, fairly well tolerated and this needs to be proven in a larger randomized phase 3 study. Further research into the pathogenesis of biliary tract cancer with the aim to identify new targets for treatments is required.

The Effect of Inflammatory Markers on Survival in Advanced Biliary Tract Carcinoma Treated with Gemcitabine/Oxaliplatin Regimen

BACKGROUND

In advanced biliary tract carcinoma (BTC), the prognosis is very poor, and the overall survival is less than 1 year. This study aimed to determine the effect of neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), C-reactive protein (CRP)/albumin ratio (CAR), and prognostic nutritional index (PNI) on the survival of BTC patients treated with gemcitabine/oxaliplatin (GEMOX) regimen.

METHODS

Data of 53 patients with advanced BTC were evaluated retrospectively. Association between inflammatory markers and 6-month PFS and 12-month OS were compared by the log-rank test. The optimal cutoff values were determined by a receiver operating characteristic (ROC) curve analysis. NLR, dNLR, CAR, and PNI were grouped based on cutoff points 1.95, 1.15, 0.57, and 33, respectively. Univariate and multivariate analyses were used to assess their prognostic values for survival.

RESULTS

Lower dNLR (< 1.15) was prognostic for higher 6-month PFS and 12-month OS rates, while lower NLR (< 1.95) was prognostic for higher 6-month PFS rates only. CAR and PNI did not have statistically significant effects on survival.

CONCLUSIONS

Pretreatment dNLR and NLR values in advanced BTC can be used as predictive markers for survival in patients undergoing the GEMOX regimen.

Multi-institutional retrospective analysis of FOLFIRI in patients with advanced biliary tract cancers

BACKGROUND

Gemcitabine plus platinum is the standard of care first-line treatment for advanced biliary tract cancers (BTC). There is no established second-line therapy, and retrospective reviews report median progression-free survival (PFS) less than 3 mo on second-line therapy. 5-Fluorouracil plus irinotecan (FOLFIRI) is a commonly used regimen in patients with BTC who have progressed on gemcitabine plus platinum, though there is a paucity of data regarding its efficacy in this population.

AIM

To assess the efficacy of FOLFIRI in patients with biliary tract cancers.

METHODS

We retrospectively identified patients with advanced BTC who were treated with FOLFIRI at MD Anderson, University of Michigan and Mayo Clinic in Jacksonville. Data were collected on patient demographics, BTC subtype, response per RECIST v1.1, progression and survival.

RESULTS

Ninety-eight patients were included of which 74 (75%) had metastatic and 24 (25%) had locally advanced disease at the time of treatment with FOLFIRI. The median age was 60 (range, 22-86) years. The number of patients with extrahepatic cholangiocarcinoma, gall bladder cancer and intrahepatic cholangiocarcinoma were 10, 17 and 71, respectively. FOLFIRI was used as 1^st, 2^nd, 3^rd or 4^th – N^th lines in 8, 50, 36 and 4 patients, respectively. Median duration on FOLFIRI in the entire cohort was 2.2 (range, 0.5-8.4) mo. The median PFS and overall survival were 2.4 (95% confidence interval (CI): 1.7-3.1) and 6.6 (95%CI: 4.7-8.4) mo, respectively. Median PFS for patients treated with FOLFIRI in 1^st, 2^nd, 3^rd or 4^th – N^th lines were 3.1, 2.5, 2.3 and 1.5 mo, respectively. Eighteen patients received concurrent bevacizumab (n = 13) or EGFR-targeted therapy (n = 5) with FOLFIRI, with a median PFS of 2.7 mo (95%CI: 1.7-5.1).

CONCLUSION

In this largest multi-institution retrospective review of 98 patients with BTC treated with FOLFIRI, efficacy appears to be modest with outcomes similar to other cytotoxic chemotherapy regimens.

Inoperable Biliary Tract and Primary Liver Tumors: Palliative Treatment Options

Primary liver tumors are most commonly hepatocellular carcinoma and intrahepatic cholangiocarcinoma. Although surgical resection offers a chance for cure, these tumors generally present at a late, inoperable stage, necessitating an understanding of noncurative and palliative treatment options. These options include ablative therapies, including radiofrequency ablation; intra-arterial therapies, including transcatheter chemoembolization; biliary decompression; radiotherapy; systemic therapies, including traditional chemotherapeutic agents; and molecular therapies, such as sorafenib. Selection of nonoperative treatment depends on patient and tumor factors as well as institutional resources and expertise.

The Efficacy of Different Chemotherapy Regimens for Advanced Biliary Tract Cancer: A Systematic Review and Network Meta-Analysis

Background: Although gemcitabine plus cisplatin (GP) is considered as standard chemotherapy for patients with advanced biliary tract cancer (BTC), the optimal regimen remains unknown.

Methods: Using Network meta-analysis (NMA), a systematic review was conducted to find the most effective chemotherapy regimen for advanced BTC. We searched PubMed, Web of Science, Embase, Scopus and the Cochrane Library for articles published before October 6, 2018. Articles about chemotherapeutic comparisons were included. Hazard ratios (HRs) for overall survival (OS) and progression free survival (PFS) were estimated while odd ratios (ORs) was assessed for objective response rate (ORR).

Results: The NMA included 25 studies and 3,312 individuals. Among all the regimens, Folfox-4 regimen obtained a superior difference in OS (BSC vs. Folfox-4, HR 3.4, 95% CI 1.7-6.7). XP was slightly better than GP in OS and GS approximately obtained the same efficacy to GP (HR for XP vs. GP 0.74, 95% CI 0.51-1.1; HR for GS vs. GP 1.1, 95% CI 0.71-1.5). Most of the targeted therapies included in this study tend to achieve better results in PFS and ORR but failed to improve OS, in which E-GEMOX achieved the best ORR when compared to BSC (OR 0.03, 95% CI 0.00-0.94).

Conclusions: Folfox-4 regimen is likely to be the optimal chemotherapy for patients with advanced BTC and the predominant targeted therapy hasn't achieved significant success currently. XP and GS can be considered as alternatives for advanced BTC.

Drug development and clinical trial design in pancreatico-biliary malignancies

Pancreatico-biliary (P-B) tumors arise from the pancreas, bile duct, and ampulla of Vater. Despite their close anatomical location, they have different etiology and biology. However, they uniformly share a poor prognosis, with no major improvements observed in overall survival over decades, even in the face of progress in diagnostic imaging and surgical techniques, and advances in systemic and loco-regional radiation therapies. To date, cytotoxic treatment has been associated with modest benefits in the advanced disease setting, and survival for patients with stage IV disease has not exceeded a year. Therefore, there is a pressing need to identify better treatments which may impact more significantly. Frequently, encouraging signals of potential efficacy for novel agents in early phase clinical trials have been followed by disappointing failures in larger phase III trials, raising the valid question of how drug development can be optimized for patients with pancreatic adenocarcinoma and biliary tract malignancies. In this article we summarize the current therapeutic options for these patients and their limitations. The biological context of these cancers is reviewed, highlighting features that may make them resistant to standard chemotherapeutics and could be potential therapeutic targets. We discuss the role of early phase clinical trials, defined as phase I and non-randomised phase II trials, within the clinical context and current therapeutic landscape of P-B tumors and postulate how translational studies and trial design may enable better realization of emerging targets together with a proposed model for future patient management. A detailed summary of current phase I clinical trials in P-B tumors is provided.

Diagnosis and Management of Intrahepatic and Extrahepatic Cholangiocarcinoma

Cholangiocarcinomas (CC) are rare tumors which usually present late and are often difficult to diagnose and treat. CCs are categorized as intrahepatic, hilar, or extrahepatic. Epidemiologic studies suggest that the incidence of intrahepatic CCs may be increasing worldwide. In this chapter, we review the risk factors, clinical presentation, and management of cholangiocarcinoma.

The efficacy and safety of different pharmacological interventions for patients with advanced biliary tract cancer: A network meta-analysis

Biliary tract cancer (BTC) is the second common cancer in liver cancer. Chemotherapy is the mainstay of treatments for patients with advanced or metastatic disease, while fluorouracil (FU)-based and gemcitabine (GEM)-based treatments are most widely applied. This NMA aimed to figure out whether the addition of platinum (PLA) and target agents (TAR) can influence the efficacy and safety of standard chemotherapy. Network meta-analysis (NMA) was conducted based on the records from PubMed, Embase and Cochrane. Eligible data was extracted from available qualified trials and outcomes. Software R 3.2.3 and STATA 13.0 were used to conduct the Bayesian NMA, calculating odds ratios (ORs) and hazard ratios (HRs) with 95% credible interval (CrI) to evaluate different treatments.Almost all treatments were superior to best supportive care (BSC) and FU in terms of 1-OS, 2-OS and 1-PFS. GEM+PLA and GEM+PLA+TAR exhibited better efficacy than most treatments in 1-OS, 2-OS and 1-PFS, and yielded better results than BSC and GEM+FU in terms of 2-PFS. Most drug-containing treatments reported higher overall response rate (ORR) than BSC. GEM and GEM+FU were associated with a higher risk of neutropenia and thrombocytopenia compared to FU, FU+PLA and GEM+PLA. No statistical difference was detected in terms of nausea and vomiting.GEM+PLA and GEM+PLA+TAR were both efficacious and were associated with fewer adverse events. In conclusion, the addition of PLA can significantly improve the efficacy of FU and GEM-based treatments, and the addition of TAR to GEM+PLA can contribute to further improvement, but with a mild increase of adverse events.

Hepatopancreatoduodenectomy for perihilar cholangiocarcinoma following laparoscopic total gastrectomy

•

Surgical resection is the only curative treatment for perihilar cholangiocarcinoma.

•

Hepatopancreatoduodenectomy for biliary cancers after total gastrectomy is a challenging procedure with high morbidity and mortality rates.

•

However, this procedure can provide the chance for long-term survival if curative resection is feasible.

•

This case was the first report of hepatopancreatoduodenectomy following laparoscopic total gastrectomy.

Introduction

Surgical resection is the only curative treatment for perihilar cholangiocarcinoma. However, Hepatopancreatoduodenectomy (HPD) procedure remains controversial in regard to the balance between the survival benefit and high risk of mortality and morbidity.

Presentation of case

A 72-year-old man who was revealed the dilation of intrahepatic hepatic duct by computed tomography after laparoscopic total gastrectomy was referred to our hospital. The patient had undergone laparoscopic total gastrectomy with Roux-en-Y esophageal-jejunostomy reconstruction 1 year previously. By several examinations, we consequently diagnosed this case as a perihilar cholangiocarcinoma and performed HPD. Histological examination revealed a well differentiated adenocarcinoma without lymph-node metastasis and a negative margin of liver parenchyma and pancreas. He was recovered from a grade B pancreatic fistula by conservative therapy and discharged post-operatively on day 64 in good health. The patient received postoperative systemic chemotherapy with gemcitabine for 6 months. 16 months after surgery, the patient has had no recurrence.

Discussion

HPD for biliary and cancers after total gastrectomy is a challenging procedure with high morbidity and mortality rates. However, this procedure can provide the chance for long-term survival if curative resection is feasible.

Conclusion

This case was the first report of hepatopancreatoduodenectomy following laparoscopic total gastrectomy.

Phase II study of fixed dose-rate gemcitabine plus S-1 as a second-line treatment for advanced biliary tract cancer

PURPOSE

Gemcitabine plus platinum is considered standard first-line chemotherapy for patients with advanced biliary tract cancer. However, no standard second-line therapy has been established for this disease. According to reports, S-1 exerts anti-tumor effects on advanced biliary tract cancer and gemcitabine is more effective via fixed dose-rate administration. We evaluated the efficacy and safety of a combination of fixed dose-rate gemcitabine and S-1 after failure of gemcitabine or gemcitabine plus cisplatin therapy.

METHODS

This single-arm phase II study (clinical trial number: UMIN000005918) set the response rate as the primary endpoint and used a MiniMax two-stage design with a null hypothesis < 7% and alternative hypothesis ≥ 25%. Thirty-five patients were needed to yield a power of 90% and α value of 0.05. Patients received gemcitabine (1000 mg/m², div, 100-min period, day 1) and S-1 (40 mg/m² twice daily, oral, days 1-7), every 2 weeks until disease progression or intolerable adverse events were observed.

RESULTS

Forty-one patients were enrolled, and 3 of 23 first-stage patients responded. The overall response rate was 9.8% [95% confidence interval (CI): 2.7-19.2%]. The median overall and progression-free survival were 7.0 [95% CI: 5.3-8.6] and 2.6 months (95% CI: 1.6-3.5), respectively. The most common grade 3-4 adverse events were leukopenia (19.5%), neutropenia (19.5%), anemia (14.6%), thrombocytopenia (7.3%), and anorexia (4.8%).

CONCLUSION

Second-line fixed dose-rate gemcitabine plus S-1 was not sufficiently effective and tolerable in patients with advanced biliary tract cancer refractory to gemcitabine or gemcitabine plus cisplatin.

Efficacy of fluoropyrimidine-based chemotherapy in patients with advanced biliary tract cancer after failure of gemcitabine plus cisplatin: retrospective analysis of 321 patients

Background:

We aimed to assess the efficacy of second-line fluoropyrimidine-based chemotherapy in patients with advanced biliary tract cancer (BTC) after failure of gemcitabine plus cisplatin (GEMCIS).

Methods:

We retrospectively examined patients with histologically documented advanced BTC who received first-line GEMCIS between December 2010 and June 2015. Among 748 patients treated with first-line GEMCIS, 321 (43%) subsequently received fluoropyrimidine-based second-line systemic chemotherapy.

Results:

Fluoropyrimidine monotherapy and fluoropyrimidine–platinum combination were used in 255 and 66 patients, respectively. In patients with measurable disease, the overall response rate (ORR) was 3% and disease control rate was 47%. After a median follow-up of 27.6 months (range, 0.9–70.4 months), the median progression-free survival (PFS) and overall survival (OS) were 1.9 months (95% confidence interval (CI), 1.6–2.2) and 6.5 months (95% CI, 5.9–7.0), respectively. The ORR was significantly higher in patients who received fluoropyrimidine–platinum combination compared with those who received fluoropyrimidine alone (8 vs 1%, P=0.009), although the PFS (P=0.43) and OS (P=0.88) did not significantly differ between these groups.

Conclusions:

Fluoropyrimidine-based chemotherapy was modestly effective as a second-line chemotherapy for advanced BTC patients after failure of GEMCIS. Fluoropyrimidine–platinum combination therapy was not associated with improved survival outcomes, as compared with fluoropyrimidine monotherapy.

A systematic review of safety and efficacy of hepatopancreatoduodenectomy for biliary and gallbladder cancers

OBJECTIVES

To review the evidence on the safety and efficacy of hepatopancreatoduodenectomy for biliary and gallbladder cancers.

METHODS

Medline and EMBASE were systematically searched for papers of hepatopancreatoduodenectomy in patients with biliary and gallbladder cancers.

RESULTS

Eighteen studies involving 397 patients were reviewed. Major hepatectomy was undertaken in 81.3% of the 397 patients and the R0 resection rate was 71.3%. The morbidity and mortality rates were 78.9% and 10.3%, respectively. The 5-year overall survival rate ranged from 3% to 50% (median = 31%). The 5-year survival rate in patients who underwent curative resection was 18-68.8% (median = 51.3%), and 0% in patients who received non-curative resection.

CONCLUSIONS

Hepatopancreatoduodenectomy is a challenging procedure with high morbidity and mortality rates. However, this procedure can provide a chance of long-term survival in patients in whom curative resection is feasible.

Second-line chemotherapy in advanced biliary cancer progressed to first-line platinum-gemcitabine combination: a multicenter survey and pooled analysis with published data

Background

After progression to a standard first-line platinum and gemcitabine combination (GP), there is no established second-line therapy for patients with advanced biliary tract cancers (aBTC). Indeed, literature data suggest limited activity of most second-line agents evaluated so far.

Methods

We collected a large retrospective series of aBTC patients treated with second-line chemotherapy after progression to a first-line GP regimen at different Italian institutions. We then pooled the data with those reported in previous studies, which were identified with a Medline search and the on-line abstract datasets of major international oncology meetings.

Results

A total of 174 patients were included in the multicenter survey: response rate (RR) with second-line chemotherapy was low (3.4 %), with median PFS and OS of 3.0 months and 6.6 months, respectively. At multivariate analysis, preserved performance status, low CA19.9 levels and absence of distant metastases were favorable prognostic factors. Data from other five presented or published series were identified, for a total of 499 patients included in the pooled analysis. The results confirmed marginal activity of second-line chemotherapy (RR: 10.2 %), with limited efficacy in unselected patient populations (median PFS: 3.1 months; median OS: 6.3 months).

Conclusions

The current analysis highlights the limited value of second-line chemotherapy after a first-line GP combination in aBTC. While waiting for effective biologic agents in this setting, ongoing randomized trials will identify the optimal second-line chemotherapy regimen and validate prognostic factors for individual patient management.

A systematic review of the safety and efficacy of hepatopancreatoduodenectomy for biliary and gallbladder cancers

OBJECTIVES

To review the evidence on the safety and efficacy of hepatopancreatoduodenectomy for biliary and gallbladder cancers.

METHODS

Medline and EMBASE were systematically searched for papers describing hepatopancreatoduodenectomy in patients with biliary and gallbladder cancers.

RESULTS

Eighteen studies involving 397 patients were reviewed. A major hepatectomy was undertaken in 81.3% of the 397 patients, and the R0 resection rate was 71.3%. The morbidity and mortality rates were 78.9% and 10.3%, respectively. The 5-year overall survival rate ranged from 3% to 50% (median = 31%). The 5-year survival rate in patients who underwent a curative resection was 18-68.8% (median = 51.3%), and 0% in patients who received a non-curative resection.

CONCLUSIONS

A hepatopancreatoduodenectomy is a challenging procedure with high morbidity and mortality rates. However, this procedure can provide a chance of long-term survival in patients in whom a curative resection is feasible.
