CHICAGO – Pseudocirrhosis appears radiographically similar to cirrhosis, but lacks its classic pathologic features.
The study is the largest cohort of patients with pseudocirrhosis studied to date. “It provides important clinical information about the natural history of this condition to help oncologists better understand which patients develop this condition and what complications are most common. Interestingly, we found that patients who developed ascites had a worse overall survival than patients who did not develop ascites, which was not previously reported,” said Laura Huppert, MD, who presented the findings during a poster session at the annual meeting of the American Society of Clinical Oncology.
Pseudocirrhosis is commonly found in patients with metastatic breast cancer and can lead to ascites and varices, among other complications. “These problems can be quite debilitating and even life-threatening for our patients. In order to better diagnose and treat our patients with pseudocirrhosis, we first wanted to understand the natural history of this condition, including which patients develop it, what treatments they have received, and what complications are most frequent,” said Dr. Huppert, MD, who is a hematology/oncology fellow at the University of California, San Francisco.
The study was retrospective, making it impossible to determine causality. “It is possible that the biology of HR+ disease predisposes patients to the development of pseudocirrhosis through mechanisms that are not yet elucidated. Alternatively, this may be due to the fact that patients with HR+ disease tend to have longer survival and are on systemic therapy for longer periods of time, allowing more time for pseudocirrhosis to develop in response to systemic therapy,” Dr. Huppert said.
In future work, Dr. Huppert plans to examine a control arm of patients with liver disease who do not develop pseudocirrhosis to gain a better understanding of factors that might cause the condition. She also hopes to work with hepatologists to determine if new antifibrosis agents might be applicable to pseudocirrhosis. “There may be interesting things we can learn from other disease states and apply to this condition,” she said.
The researchers analyzed data from 120 patients with pseudocirrhosis. 82.5% of patients were HR+/HER2–, 11.7% were HR+/HER2+, 2.5% were HR–/HER2+, and 3.3% were triple negative. Liver metastases were present in all patients, and 82.5% had more than 15 liver lesions.
A total of 92.5% of patients had previously undergone chemotherapy before pseudocirrhosis was identified, and the median time to diagnosis of pseudocirrhosis after diagnosis of liver metastases was 18.7 months. 50% of patients with pseudocirrhosis had stable or responding disease. After pseudocirrhosis diagnosis, patients underwent a median of 1.0 additional lines of therapy, and the median overall survival following pseudocirrhosis diagnosis was 7.9 months. A total of 80.8% of patients went on to be diagnosed with ascites, 17.5% with esophageal varices, 21.7% with splenomegaly, 10.0% with gastrointestinal bleeding, and 9.2% with hepatic encephalopathy.
Patients with radiographic evidence of ascites survived an average of 42.8 months after metastatic breast cancer diagnosis, while those without ascites survived an average of 76.2 months (P < .001).
Specialty care was rare: Just 7.5% of patients received a GI/hepatology consultation.
Dr. Huppert has no relevant financial disclosures.
