Plain English summary of protocol

Background and study aims
Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer and characterized by high invasiveness and frequent postoperative recurrence. In view of high tumor recurrence, adjuvant strategies have been explored for many years. We are in urgent need of biomarkers to better select which patients are more likely to benefit from adjuvant chemotherapy.

Who can participate?
Patients with resected ICC

What does the study involve?
We enrolled patients with primary ICC from August 2014 to July 2019 who received curative resection in the Department of Liver Surgical Oncology of Zhongshan Hospital, Fudan University, Shanghai, China, and collected tissue samples from their tumors and matched non-cancerous livers. A part of each frozen sample was subjected to whole-exome sequencing. Some frozen samples and formalin-fixed, paraffin-embedded samples were used for Sanger sequencing.

What are the possible benefits and risks of participating?
This research aims to discover new biomarkers that will help to select patients who are more likely to benefit from adjuvant chemotherapy. There were no risks of participating.

Where is the study run from?
Zhongshan Hospital, Fudan University (China)

When is the study starting and how long is it expected to run for?
January 2014 to September 2022

Who is funding the study?
1. National Natural Science Foundation of China (No. 82173260, No. 81972708, No. 82072681, No. 82003082)

Participant information sheet No participant information sheet available
Scientific titleAssociation of IDH1 mutations with survival and recurrence in resected intrahepatic cholangiocarcinoma received or not received adjuvant chemotherapy
Study objectivesThe presence of IDH1 mutations was associated with better survival and decreased risk of recurrence in patients with resected ICC who received adjuvant chemotherapy
Ethics approval(s)Approved 06/05/2021, Research Ethics Committee of Zhongshan Hospital (Zhongshan Hospital, Fudan University, 136 Yi Xue Yuan Road, Shanghai 200032, China; +86-21-31587871; ec@zs-hospital.sh.cn), ref: B2021-305
Health condition(s) or problem(s) studiedIntrahepatic cholangiocarcinoma
InterventionOur research is an observation study. No intervention was involved in the course of the study. We collected tissue samples from patients attending the Department of Pathology of Zhongshan Hospital. The team enrolled patients with primary ICC who were receiving curative resection. Tissue samples were collected from the tumors and matched non-cancerous livers. All the tissues were used for whole-exome sequencing or Sanger sequencing to discover biomarkers to better select which patients are more likely to benefit from adjuvant chemotherapy. The clinical information of patients about treatment methods and survival time were collected from the clinical information database of Zhongshan Hospital. Before surgical operation and tissue sample collection, oral and written informed consent from each participant, with information such as the use of tissue sample and clinical characteristics for scientific research, which was granted by The Research Ethics Committee of Zhongshan Hospital. Patients receiving palliative surgeries, prior interventions or who have other primary malignancies and inflammatory diseases during the follow-up were excluded from the study. Patients who received chemotherapy or not received adjuvant chemotherapy after surgery.
Intervention typeProcedure/Surgery
Primary outcome measure1. Disease-free survival (DFS), defined as the interval between the surgery and any diagnosis of recurrence, measured using data collected every 3 months in the clinical information database of Zhongshan Hospital at one timepoint
2. Overall survival (OS), defined as the time from the date of surgery until death or to the end of follow-up, measured using data collected every 3 months in the clinical information database of Zhongshan Hospital at one timepoint
Secondary outcome measuresGene mutation measured using whole-exome sequencing or Sanger sequencing at one timepoint
Overall study start date01/01/2014
Completion date30/09/2022
