Overall survival in gallbladder surgery not significantly affected by volume of liver resection
USA: A recent study published in Annals of Surgical Oncology found no difference in overall survival rate based on how much of the liver is resected provided the cancer is completely removed among patients undergoing gallbladder cancer surgery.
“When the surgery to remove gallbladder cancer is successful and all the cancer is removed, the amount of liver that is removed doesn't seem to make a big difference in how long patients live,” said corresponding author Eduardo Vega, MD, assistant professor of surgery at Boston University Chobanian & Avedisian School of Medicine.
Gallbladder cancer is most common in people who have gallstones or have had gallstones in the past. While uncommon, most gallbladder cancers are discovered at a late stage when the prognosis is often poor and liver resection is pivotal for treatment. However, there is debate about how much of the liver should be removed when performing gallbladder cancer surgery.
To address the lack of consensus regarding optimal resection, the researchers reviewed the medical records of 101 patients of Hospital Sotero del Rio Chile who had surgery to remove gallbladder cancer between 1999 and 2018. Chile has one of the highest incidences of gallbladder cancer in the world.
