Background/aim: Palliative irradiation is effective in alleviating symptoms in patients with metastatic cancer in general. However, little data exist regarding irradiation of metastatic bile duct cancer. Selection of the best regimen for such a patient should be based on their survival prognosis.
Patients And Methods: This study included five patients irradiated for metastatic bile duct cancer and aimed to identify predictors of survival by analyzing six factors: age, gender, general condition (Karnofsky performance score), metastatic site receiving palliative irradiation, metastases outside irradiated sites and time between diagnosis of bile duct cancer and palliative irradiation.
Results: In the whole series, median survival was 3 months. Survival rates at 3 and 6 months were 40% and 40%, respectively. A Karnofsky performance score >70% had a borderline significant association with better survival (p=0.05).
Conclusion: Karnofsky performance score was identified as predictor of survival and should be considered when assigning the radiation regimen to patients with metastatic bile duct cancer.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) has become the gold standard management for patients who present with common bile duct stone (CBDS). Although laparoscopic cholecystectomy is generally recommended for patients who have CBDS clearance, there is still a significant proportion of patients who are managed expectantly. Our study aimed to evaluate the outcomes of expectant management (EM) versus prophylactic cholecystectomy after initial endoscopic removal of CBDS.

Hilar Cholangiocarcinoma (h-CCA) originates from the epithelial cells, which characters as longitudinal growth along the bile ducts and invasion of peripheral vascular nerves. Due to the tumours insidious progression and usually become advanced stage disease at presentation, patients' mortality could parallel incidence rates. For patients who are not amenable to resection, systemic therapy and palliative treatment become the way to go.

As a leading cause of morbidity and mortality, fibrosis is the common pathway of various chronic inflammatory diseases in organs and causes death in a large number of patients. It can destroy the structure and function of organs and ultimately lead to organ failure, which is a major cause of disability and death in many diseases. However, the regulatory mechanism of organ fibrosis is not well clear and the lack of effective drugs and treatments, which seriously endangers human health and safety.
