Project description:Intrahepatic cholangiocarcinoma (ICC) is a rare, aggressive cancer of the biliary tract. It often presents with locally advanced or metastatic disease, but for patients with early-stage disease, surgical resection with negative margins and portahepatis lymphadenectomy is the standard of care. Recent advancements in ICC include refinement of staging, improvement in liver-directed therapies, clarification of the role of adjuvant therapy based on new randomized controlled trials, and advances in minimally invasive liver surgery. In addition, improvements in neoadjuvant strategies and surgical techniques have enabled expanded surgical indications and reduced surgical morbidity and mortality. However, recurrence rates remain high and more effective systemic therapies are still necessary to improve recurrence-free and overall survival. In this review, we focus on current and emerging surgical principals for the management of ICC including preoperative evaluation, current indications for surgery, strategies for future liver remnant augmentation, technical principles, and the role of neoadjuvant and adjuvant therapies.

Project description:Intrahepatic cholangiocarcinoma (iCCA) is a rare and complex malignancy of the biliary epithelium. Due to its silent presentation, patients are frequently diagnosed late in their disease course, resulting in poor overall survival. Advances in molecular profiling and targeted therapies have improved medical management, but long-term survival is rarely seen with medical therapy alone. Surgical resection offers a survival advantage, but negative oncologic margins are difficult to achieve, recurrence rates are high, and the need for adequate future liver remnant limits the extent of resection. Advances in neoadjuvant and adjuvant treatments have broadened patient treatment options, and these agents are undergoing active investigation, especially in the setting of advanced, initially unresectable disease. For those who are not able to undergo resection, liver transplantation is emerging as a potential curative therapy in certain cases. Patient selection, favorable tumor biology, and a protocolized, multidisciplinary approach are ultimately necessary for best patient outcomes. This review will discuss the current surgical management of locally advanced, liver-limited intrahepatic cholangiocarcinoma as well as the role of liver transplantation for select patients with background liver disease.

Project description:Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver malignancy and is increasing in incidence. Long-term outcomes are optimized when patients undergo margin-negative resection followed by adjuvant chemotherapy. Unfortunately, a significant proportion of patients present with locally advanced, unresectable disease. Furthermore, recurrence rates are high even among patients who undergo surgical resection. The delivery of systemic and/or liver-directed therapies prior to surgery may increase the proportion of patients who are eligible for surgery and reduce recurrence rates by prioritizing early systemic therapy for this aggressive cancer. Nevertheless, the available evidence for neoadjuvant therapy in ICC is currently limited yet recent advances in liver directed therapies, chemotherapy regimens, and targeted therapies have generated increasing interest its role. In this article, we review the rationale for, current evidence for, and ongoing research efforts in the use of neoadjuvant therapy for ICC.

Project description:PurposeThe present study assesses long-term overall survival (OS) and disease-free survival (DFS) after curative resection for intrahepatic cholangiocarcinoma (ICCA) depending on resection margin (RM) status and lymph node (LN) status.MethodsClinical data of all consecutively resected patients with ICCA at a single high-volume center between 2005 and 2018 were collected. Minimum follow-up was 36 months. Perioperative and long-term oncological outcome was assessed.ResultsOne hundred ninety-two cases were included in the analysis. Thirty- and 90-day-mortality was 5.2% (n = 10) and 10.9% (n = 21). OS was 26 months with 1-, 2-, and 5-year-OS rates of 72%, 53%, and 26%. One-, 2-, and 5-year-DFS rates were 54%, 42%, and 35% (N0 vs. N1: 29 vs. 9 months, p = 0.116). R1 was not found to be an independent risk factor for reduced survival in the overall cohort (p = 0.098). When differentiating according to the LN status, clear resection margins were significantly associated with increased DFS for N0 cases (50 months vs. 9 months, p = 0.004). For N1 cases, no significant difference in DFS was calculated for R0 compared to R1 cases (9 months vs. 9 months, p = 0.88). For N0 cases, clear resection margins > 10 mm were associated with prolonged OS (p = 0.048).ConclusionFor N1 cases, there was no significant survival benefit when comparing R0 versus R1, while the complication rate remained high for the extended resection types. In view of merging multimodal treatment, the hilar first concept assesses locoregional LN status for optimal surgical therapy.

Project description:Intrahepatic cholangiocarcinoma (ICCA) is a rare and aggressive malignant tumor that arises from the biliary tracts in the liver. Upfront surgery with adjuvant capecitabine in patients with resectable disease is often the standard treatment. Unfortunately, only 20% of patients present with resectable disease and many individuals will develop recurrence or metastatic disease after curative-intent resection. Patients with advanced or metastatic ICCA often require multidisciplinary care with a combination of cytotoxic chemotherapy, targeted therapy, and/or locoregional therapies. Gemcitabine plus cisplatin is currently first line therapy for advanced or metastatic ICCA. In recent years, efforts have been focused to develop more effective targeted therapy, most commonly with FGFR and IDH inhibitors for ICCA. Despite these efforts, ICCA still carries a poor prognosis. We herein review the current clinical management of ICCA focusing on surgical technique and systemic therapies.

Project description:Intrahepatic cholangiocarcinoma (iCC) is distinguished as an entity from perihilar and distal cholangiocarcinoma and gallbladder carcinoma. Recently, molecular profiling and histopathological features have allowed further classification. Due to the frequent delay in diagnosis, the prognosis for iCC remains poor despite major technical advances and multimodal therapeutic approaches. Liver resection represents the therapeutic backbone and only curative treatment option, with the functional residual capacity of the liver and oncologic radicality being deciding factors for postoperative and long-term oncological outcome. Furthermore, in selected cases and depending on national guidelines, liver transplantation may be a therapeutic option. Given the often advanced tumor stage at diagnosis or the potential for postoperative recurrence, locoregional therapies have become increasingly important. These strategies range from radiofrequency ablation to transarterial chemoembolization to selective internal radiation therapy and can be used in combination with liver resection. In addition, adjuvant and neoadjuvant chemotherapies as well as targeted therapies and immunotherapies based on molecular profiles can be applied. This review discusses multimodal treatment strategies for iCC and their differential use.

Project description:BackgroundThis study aimed to determine the role of surgical treatment in patients with stage II intrahepatic cholangiocarcinoma (iCCA).MethodsData were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. We divided stage II iCCAs into solitary tumors with vascular invasion (T2sN0M0) and multiple tumors with/without vascular invasion (T2mN0M0) according to the criteria of AJCC v.8. The Kaplan-Meier method and log-rank test were used to evaluate differences in overall survival (OS). We performed two propensity score-matching analyses with (PSM2) or without (PSM1) surgical treatment.Results667 and 778 iCCA patients with stage II and IIIB were recruited. After PSM2, there was no survival difference in stage II iCCA patients in hypothetical conditions with similar surgical proportions (p = 0.079). However, OS was significantly worse in patients with T2mN0M0 than T2sN0M0 when the actual surgical proportion existed after PSM1 (p < 0.001). OS was similar between T2mN0M0 and IIIB regardless of whether PSM1 (p = 0.907) or PSM2 (p = 0.699) was performed. The surgical treatment was verified to associate with prognosis.ConclusionsThe survival benefit by surgical treatment was existed in Stage II but not in Stage IIIB iCCA patients. The OS for T2mN0M0 will approach that of T2sN0M0 if the surgical proportion is gradually increased.

Project description:Aim: We aimed to compare the survival outcomes of radiofrequency ablation (RFA) and surgical resection (SR) for patients with small early-stage primary intrahepatic cholangiocarcinoma (ICC). Methods: Patients with small (≤5 cm) and early-stage ICC were screened from the Surveillance, Epidemiology, and End Results (SEER) database. Overall survival (OS) and cancer-specific survival (CSS) rates between the SR and RFA patients were evaluated. The results were verified using an inverse probability-weighting model (IPTW). Results: In total, 184 patients with small T1 stage ICC that received RFA or SR treatment were identified. The OS rates at 1, 3, and 5 years were 87.4, 73.3, and 61.5% for patients who underwent SR, respectively, and 89.9, 42.4, and 23.9%, respectively, for patients who received RFA. CSS rates at 1, 3, and 5 years were 91.5, 73.8, and 66.1%, respectively, for the SR group and 93.5, 53.4, and 30.0%, respectively, for the RFA group. The OS and CSS rates were evaluated to be significantly better in the SR group than in the RFA group after the multivariate Cox regression and IPTW analysis. Subsequently, the survival benefit of SR was also observed in the subgroup of patients with <4.5 or <4 cm early-stage ICC when compared with RFA. Conclusion: Our results indicated that the SR provided a significantly better prognosis than RFA in patients with small and early-stage ICC. SR as the first-line treatment of primary early-stage ICC is still recommended. However, prospective randomized controlled trials with larger sample sizes are required to compare these modalities in the treatment of ICC.

Project description:BackgroundIntrahepatic cholangiocarcinoma (iCCA) is a rare biliary tract cancer with increasing incidence and poor survival rates. This study aims to evaluate the incidence and survival trends of iCCA patients over 20 years using a national cancer database, and assess the temporal association between survival and landmark clinical trials.MethodsData was extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Age-adjusted incidence rates (AAIRs) were calculated from 2000 to 2020. Overall survival was analyzed based on diagnosis time and disease stage. Subgroup analysis was performed for patients diagnosed between 2015 and 2020. Landmark clinical trials were reviewed to determine temporal changes in survival.ResultsIn this analysis of 28,918 iCCA patients, the AAIR increased from 0.49 per 100,000 in 2000 to 1.38 in 2020 [annual percent change (APC) 6.94, 95% confidence interval (CI): 6.32 to 7.56], with a notable decline from 2019 to 2020. Incidence rates overall displayed an uptrend course across subgroups divided by sex, race, age, and disease stage. The age-adjusted median overall survival (mOS) improved from 5.28 months in 2000 to 9.3 months in 2013, then stabilized between 8.0-9.0 months after 2013. Using 2010 as a cutoff, when the ABC-02 trial was published, the decade-based mOS increased from 6.55 months in 2000-2010 to 9.06 months in 2010-2020. During 2015-2020, the overall mOS was 8.8 months, with mOS of 24.3, 12.1, and 5.4 months for local, regional, and distant stages, respectively.ConclusionsThe study indicates a steady rise in iCCA incidence since 2000 across all subgroups. Survival rates improved since 2000 but stabilized after 2013, following the ABC-02 trial publication in 2010. The impact of more recent clinical trials on survival rates requires further analysis in the coming years.
