Radioactive Seed-guided Resection of Cholangiocellular Carcinoma in Cirrhotic Patients

Study Overview
=================
Brief Summary
-----------------
Detection of cholangiocellular and hepatocellular carcinomas can be challenging in both radiologic imaging and during surgical resection. Therefore, radioactive seed-guided resection of these tumors, analogously to breast cancer, could be an interesting approach. The investigators present two cases of cirrhotic patients where this method of tumor labelling was used.

Detailed Description
-----------------
The investigators selected two cases of patients with liver cirrhosis where seed-guided liver resection was used. Seed-guided resection is procedure that is usually commonly used in breast cancer surgery but so far not in liver surgery. This report emphasizes the difficulties, which surgeons and radiologists may face in tumor entities that are difficult to identify both macroscopically, by palpation and intraoperative imaging techniques. The first case was a patient suffering from suspected hepatocellular carcinoma with the background of alcoholic liver cirrhosis. This patient already underwent liver surgery to remove the suspected tumour but the lesion could not be removed correctly as identification was not possible neither with palpation nor with the help of intraoperative ultrasound. For this reason, the patient was selected for seed-guided resection. The second patient, who presented nine months after the first one, presented with the suspicion of cirrhosis, two lesion small in size and in a surgically difficult localization. Therefore, the patient was selected for seed-guided resection.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| R0-Resection according to the tumour classification system | Removal of the tumour in healthy tissue, which means that microscopically no tumour tissue is detectable in the resection margin of the removed tissue. This is always examined by a trained pathologist. | 1 week after operation | 
| Procedure-Safety (No residual source of radiation) | Complete seed extraction was confirmed intraoperatively by specimen radiography immediately after tissue removal and by ensuring that no residual source of radiation is traceable in the patient with the gamma probe system. | 1 Day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of patients without side effects | Clinical follow up of the patients to ensure that there are no side effects from implanting the Seed in the liver | 6 months |
