Filter by:The extent of intrahepatic infiltration of perihilar cholangiocarcinoma (PHCC) remains unclear. This research aimed to explore the pattern and extent of intrahepatic infiltration of PHCC to guide surgical treatment and pathological research. This prospective study included 62 participants diagnosed with PHCC who underwent major hepatectomy. A whole-mount digital liver pathology system (WDLPS) for hepatectomy specimens greater than 10 × 10 cm was used to panoramically assess the intrahepatic infiltration extent of PHCC.
Background Bile duct cancer (cholangiocarcinoma) represents the second most common type of hepatobiliary cancer worldwide with an incidence of 0.35 to 2 per 100.000 annually. Currently, surgical resection is the only curative option. However, patients are not eligible for surgery if the tumor cannot be resected or the cancer has spread. For this group of patients, palliative chemotherapy is the most suited treatment option. To find out if a patient is suited for surgery, CT and MRI are performed. These imaging techniques, however, struggle to correctly identify small cancer spreads that are smaller than 1 cm. Therefore, cancer that has already spread can be found during surgery. In these cases, the tumor cannot be removed and the surgery therefore has not been of any benefit for the patient. These surgeries could be avoided by implementing a diagnostic tool with significantly higher accuracy than those currently used. Single center studies have shown that fibroblast activation protein inhibitor (FAPI) PET-CT is a very promising technique for determining metastases in tumors with prominent desmoplastic reactions, like cholangiocarcinoma. The investigators predict that implementation of preoperative FAPI PET-CT could prevent futile surgery for at least half of patients in whom intra-operative metastasized disease is found using the current work-up. Patient population Patients ≥18 years with potentially curable proximal cholangiocarcinoma (perihilar, intrahepatic and gall bladder cholangiocarcinoma) who are planned to undergo surgery based on imaging using CT thorax/abdomen and MRI of the upper abdomen. Exclusion criteria are previous abdominal surgery or chemotherapy, known pregnancy or lactation and indication for FDG PET-CT. Participation in this study Participation would mean to undergo FAPI PET-CT prior to the scheduled surgery. This will take up about half a day of the participant's time. Afterwards, participants receive questionnaires about quality of life and use of healthcare services over a period of six months in order for the researchers to be able to calculate the cost-effectiveness of additional FAPI PET-CT. Risks and benefits of participation Patients may benefit directly from [18F]F-FAPI PET-CT by allowing for more targeted treatment, possibly avoiding futile surgery and receiving chemotherapy or best clinical support instead, minimizing treatment delay. Avoiding futile surgery will also prevent patients from being exposed to the risks and discomfort associated with surgery: hospital stay, possibility of intraoperative or postoperative complications, postoperative pain and recovery, and mortality. Potential risks and burdens associated with this study are an extra hospital visit and a time burden of approximately half a day. Risks associated with administering FAPI are (re)bleed and infection. Both risks have a minimal probability of onset and can usually easily be treated. As [18F]F-FAPI is a sub-pharmacologically micro-dosed diagnostic tracer, the risk of allergic reactions is expected to be minimal and no tissue damage is expected. The burden associated with undergoing a PET-CT may be laying still for a certain time, and possible experience of claustrophobia. Possible metastases of the cancer will have to be confirmed when suspicious findings are seen on FAPI PET-CT. This could mean that participants will have to undergo additional testing such as imaging (CT or MRI) or biopsy. Undergoing FAPI PET-CT prior to surgery will result in a surgical delay when compared with the current clinical practice. The investigators do not expect this delay to influence the patient's prognosis. Follow-up will result in a time burden for patients to answer questionnaires on a two-weekly or monthly basis.
It is sometimes difficult to precisely understand whether a primary liver cancer is a hepatocellular carcinoma or a cholangiocarcinoma. The researchers will develop and validate a liquid biopsy, based on exosomal content analysis and powered by machine learning, to help clinicians differentiate these two cancers before surgery.
Neoadjuvant chemo- and immunotherapy ameliorate the recurrence rate of cholangiocarcinoma (CCA) at 12 months after surgery.
The overall goal of the WU-PE-CGS is to build a rigorous, scientific evidence base for approaches that direct engagement of cancer patients and post-treatment cancer survivors as participants in cancer research, and to investigate the impact of directly engaging participants in decisions regarding returning of genomic results on participants' health and satisfaction. Participants in this study will be presented with the choice of types of genomic results to receive, and the Engagement Optimization Unit (EOU) will investigate the impact of this intervention on participant knowledge, expectations of benefit, personal utility, and decisional conflict.
This is a randomized trial to compare the standard echoendoscope with the newly developed EndoSound Visual System in the evaluation of lesions in the gastrointestinal tract.
This study is a single-arm Phase II clinical trial aiming to evaluate the safety and efficacy of HAIC combined with Cadonilimab and Regorafenib as second-line treatment for unresectable intrahepatic cholangiocarcinoma. The study plans to enroll approximately 45 participants. All enrolled participants will receive continuous treatment: HAIC-Gemox: Gemcitabine 1000mg/m2 on Day 1 + Oxaliplatin 85mg/m2 on Day 1, every 3 weeks (Q3W), for up to 6 treatment cycles, Cadonilimab(6mg/kg, D2, Q3W) and Regorafenib (80mg QD, Q3W) until the investigator determines that there is no longer any clinical benefit (based on comprehensive assessment including RECIST v1.1 imaging evaluation and clinical condition), intolerable toxicity, initiation of new anti-tumor therapy, or meeting other criteria for treatment discontinuation, whichever occurs first.
This study is a single-arm, open-arm, single-center clinical study to explore the efficacy and safety of HAIC in combination with Surufatinib and Toripalimab in patients with inoperable or metastatic intrahepatic cholangiocarcinoma. The study was divided into three stages: screening period, treatment period and follow-up period. During the treatment period, the tumor status was evaluated by imaging every 6 weeks (±7 days), and the efficacy was changed to every 8 weeks (±7 days) after 12 weeks until the disease progressed (RECIST 1.1) or death (during the treatment of the patient) or toxicity became intolerable. The tumor treatment status and survival status after the disease progression were recorded. Safety outcome measures included AE, changes in laboratory test values, vital signs and electrocardiogram changes.
Patients with intrahepatic cholangiocarcinoma (IHC) have relatively aggressive tumors, and the prognosis for most of these patients is dismal. Surgery is the only option that can offer potential cure, but only an estimated 20-25 % are amenable to resection. Down-staging conventional chemotherapy has a relatively low response rate (< 50 %). Patients will be included into the respective treatment arms based on their tumour characteristics and disease stage, but also based on their ability/preferences, as HAI-FUDR/DEX requires going to Oslo every fortnight for the duration of the treatment and SIRT has some limitations regarding tumour distribution. Data from the MSKCC has suggested a clinically relevant benefit from adding intrahepatic chemotherapy to systemic therapy. HAI-FUDR/DEX is not approved in Norway and can only be evaluated in a protocolized trial. Given the risk of distant disease progression with IHC, the addition of conventional systemic chemotherapy makes good clinical sense, and data from MSKCC supports this approach. SIRT is another modality also applied trans-arterially and directly into the tumour. This treatment is approved in Norway and available in Bergen and in Oslo. It is far less cumbersome to deliver and maintain than HAI-FUDR/DEX. The efficacy and safety of the two treatment groups, HAI-FUDR/DEX and SIRT, will be compared in a parallel cohort (non-randomized) design
The purpose of this study is to compare laparoscopic ablation to open ablation of liver malignancies regarding complication rates and ablation response as well as quality of life following the surgery.
