Recurrent metastatic breast cancer presenting with portal hypertension and pseudocirrhosis

The Clinical Features and Outcomes of Pseudocirrhosis in Breast Cancer

Pseudocirrhosis is a diffuse nodularity of the liver that radiologically mimics cirrhosis but is a distinct pathological process. It is seen almost exclusively in patients with liver metastases and may represent a response to systemic treatment. Data on the risk factors for pseudocirrhosis and outcomes are limited. In total, 170 patients with a diagnosis of breast cancer and pseudocirrhosis in a 10-year period were identified and retrospectively analysed. Data were collected on baseline patient characteristics, treatments received, and outcomes. Median time between diagnosis of liver metastases and diagnosis of pseudocirrhosis was 17.1 months (range, 0-149 months). In total, 89.4% of patients received chemotherapy between their diagnosis of breast cancer liver metastases and their diagnosis of pseudocirrhosis, most commonly a taxane (74.7%) or capecitabine (67.1%), and the median treatment lines received was 3. Median OS from first diagnosis of pseudocirrhosis was 7.6 months (95% CI: 6.1-9.6 months) and was longer in patients with HER2+ disease at 16.7 months (95% CI: 6.4-32.9 months), which was statistically significant. In our study, pseudocirrhosis occurred in the presence of liver metastases and was associated with a poor prognosis. HER2+ patients with pseudocirrhosis had a better prognosis than other subtypes, but we did not identify other significant predictors of survival. Chemotherapy was not a prerequisite for pseudocirrhosis development, although the majority of patients had received at least one line of chemotherapy before pseudocirrhosis was diagnosed.

Pseudocirrhosis: A Case Series with Clinical and Radiographic Correlation and Review of the Literature

BACKGROUND AND AIMS

Pseudocirrhosis is a poorly understood acquired morphologic change of the liver that occurs in the setting of metastatic malignancy and radiographically resembles cirrhosis. Pseudocirrhosis has been primarily described in metastatic breast carcinoma, with few case reports arising from other primary malignancies. We present 29 cases of pseudocirrhosis, including several cases from primary malignancies not previously described.

METHODS

Radiologic, clinical, demographic, and biomedical data were collected retrospectively and analyzed. We compared clinical and radiologic characteristics and outcomes between patients with pseudocirrhosis arising in metastatic breast cancer and non-breast primary malignancies.

RESULTS

Among the 29 patients, 14 had breast cancer and 15 had non-breast primaries including previously never reported primaries associated with pseudocirrhosis, melanoma, renal cell carcinoma, appendiceal carcinoid, and cholangiocarcinoma. Median time from cancer diagnosis to development of pseudocirrhosis was 80.8 months for patients with primary breast cancer and 29.8 months for non-breast primary (p = 0.02). Among all patients, 15 (52%) had radiographic features of portal hypertension. Radiographic evidence of portal hypertension was identified in 28.6% of breast cancer patients, compared to 73.3% of those with non-breast malignancies (p = 0.03).

CONCLUSION

Pseudocirrhosis has most commonly been described in the setting of metastatic breast cancer but occurs in any metastatic disease to the liver. Our study suggests that portal hypertensive complications are more common in the setting of non-breast primary cancers than in metastatic breast cancer. Prior exposure to multiple chemotherapeutic agents, and agents known to cause sinusoidal injury, is a common feature but not essential for the development of pseudocirrhosis.

Clinical characteristics and outcomes in patients with metastatic breast cancer and pseudocirrhosis: a single center retrospective cohort study

PURPOSE

Pseudocirrhosis is a term used to describe changes in hepatic contour that mimic cirrhosis radiographically, but lack the classic pathologic features of cirrhosis. This radiographic finding is frequently found in patients with metastatic breast cancer (MBC), but the risk factors and clinical consequences are poorly understood.

METHODS

In this retrospective study, we identified patients with MBC and pseudocirrhosis who were treated at a single center from 2002 to 2021. We used chart extraction and radiology review to determine demographic characteristics, treatment history, imaging features, and complications of pseudocirrhosis.

RESULTS

120 patients with MBC and pseudocirrhosis were identified with the following BC subtypes: hormone receptor (HR) positive, HER2 negative (n = 99, 82.5%), HR+/HER2+ (n = 14, 11.7%), HR- /HER2+ (n = 3, 2.5%), and triple negative (TNBC; n = 4, 3.3%). All patients had liver metastases and 82.5% (n = 99) had > 15 liver lesions. Thirty-six patients (30%) presented with de novo metastatic disease. Median time from MBC diagnosis to pseudocirrhosis was 29.2 months. 50% of patients had stable or responding disease at the time of pseudocirrhosis diagnosis. Sequelae of pseudocirrhosis included radiographic ascites (n = 97, 80.8%), gastric/esophageal varices (n = 68, 56.7%), splenomegaly (n = 26, 21.7%), GI bleeding (n = 12, 10.0%), and hepatic encephalopathy (n = 11, 9.2%). Median survival was 7.9 months after pseudocirrhosis diagnosis. Radiographic ascites was associated with shorter survival compared to no radiographic ascites (42.8 vs. 76.2 months, p =  < 0.001).

CONCLUSIONS

This is the largest case series of patients with MBC and pseudocirrhosis. Nearly all patients had HR+ MBC and extensive liver metastases. Survival was short after pseudocirrhosis and prognosis worse with radiographic ascites.

Pseudocirrhosis and portal hypertension in patients with metastatic cancers: a systematic review and meta-analysis

Pseudocirrhosis is a clinical and radiological entity mimicking liver cirrhosis in patients without a history of chronic liver disease. We performed a systematic review and meta-analysis of the current literature to evaluate the state-of-the-art and investigate the epidemiology and clinical features of pseudocirrhosis. We searched PubMed, Web of Science and Scopus for literature published until February 28, 2022. We included in the final analysis 62 articles (N = 389 patients): 51 case reports (N = 64 patients), 5 case series (N = 35 patients) and 6 observational studies (N = 290 patients). About 80% of patients included in the case reports and case series had breast cancer. Most patients had at least one clinical sign of portal hypertension and ascites was the most common clinical manifestation of portal hypertension. The median time from pseudocirrhosis to death was 2 months (IQR 1-7 months). Alkylating agents and antimitotics were the most common classes of anticancer drugs reported in our study population. Notably, about 70% of patients received three or more anticancer drugs. Finally, pseudocirrhosis is a condition that occurs in patients with hepatic metastases and may have a negative impact on survival and clinical management of patients because of the potential development of portal hypertension and its complications.

Liver metastases - An unusual cause of portal hypertension: A case report

Introduction

Portal hypertension is a rare complication of liver metastases. The study highlights that clinician should be aware of conditions mimicking cirrhosis with similar clinical presentation and imaging findings.

Case presentation

We present the case of a 29-year-old non-alcoholic lady who presented to our hospital with a history of two months of progressive, painless abdominal distension and progressively increasing yellowish discoloration of the eyes. Physical examination, laboratory investigations, and imaging tests led to a diagnosis of multiple metastases from breast carcinoma to the liver leading to portal hypertension after exclusion of other causes of portal hypertension. However, after three weeks of presentation to the hospital, the patient died before any therapeutic measures were initiated to address breast carcinoma.

Clinical discussion

Liver metastasis from primary breast carcinoma rarely presents with clinical symptoms of portal hypertension. Although portal hypertension secondary to pseudocirrhosis, predominantly linked to ongoing chemotherapy for known cancers, has been previously described in case studies, our case had an unusual presentation leading to diagnostic uncertainty.

Conclusion

Our case highlights the rare cause of liver metastasis secondary to breast carcinoma, which presented as portal hypertension.

Transjugular intrahepatic portosystemic shunt for the management of symptomatic malignant pseudocirrhosis

BACKGROUND

Pseudocirrhosis is defined by radiologic changes of the liver parenchyma secondary to metastatic disease and/or cancer treatments, and portends a high rate of morbidity and mortality from sequelae of portal hypertension. Transjugular intrahepatic portosystemic shunt (TIPS) is an effective treatment for portal hypertension; however, TIPS is relatively contraindicated in the setting of hepatic metastases. The study aims to determine the technical efficacy and clinical outcomes of patients undergoing TIPS for symptomatic pseudocirrhosis.

METHODS

Retrospective analysis of patients with hepatic malignancy who underwent TIPS between 2008 and 2020 at a single tertiary care center. Patients with imaging findings of pseudocirrhosis and without history of primary liver malignancy or confounding causes of cirrhosis were included. West Haven scores assessing hepatic encephalopathy were obtained from chart review. Technical success was defined as successful TIPS creation with reduction in the portosystemic gradient (PSG). Clinical success was defined as resolution of variceal bleeding and/or ascites.

RESULTS

Nine patients (4 female/5 male), average (± SD) age 61.2±9.5 years with metastatic pseudocirrhosis were included for analysis. Primary malignancy was colorectal adenocarcinoma (n=5), neuroendocrine tumor (n=3), and malignant endothelial hemangioendothelioma (n=1). Average Model for End Stage Liver Disease (MELD-Na) score was 15.7±3.7. Technical success was 8/9 (89%) with average PSG reduced from 23.5±11.0 to 6.5±2.8 mmHg (P=0.001). Clinical success was 6/9 (67%). Two patients required TIPS revision after initial clinical success. Mild-moderate HE occurred in 6/9 patients post TIPS (67%), with a highest West Haven score of 2. Time from TIPS to death for acute variceal bleeding and ascites was 4.9±4.2 and 12±16.5 months, respectively. Cause of death was disease progression (n=5), variceal bleeding (n=1), or unavailable (n=2).

CONCLUSIONS

TIPS in the setting of malignant pseudocirrhosis can be created safely with similar clinical outcomes to TIPS performed for benign disease. Rates of low-grade hepatic encephalopathy may be higher amongst patients undergoing TIPS for pseudocirrhosis.

Pseudocirrhosis in Breast Cancer - Experience From an Academic Cancer Center

Background

Pseudocirrhosis is characterized by radiological changes in the liver that resemble cirrhosis, but with more rapid onset and progression. Though reported most frequently in patients with metastatic breast cancer, little is known about its prognostic factors and impact on breast cancer outcomes.

Methods

In this observational study, we reviewed abdominal CT and/or MRI scan reports of all patients with invasive breast cancer diagnosed at our center, during a ten-year period, to identify patients with pseudocirrhosis. Exclusion criteria included lack of baseline imaging, pre-existing cirrhosis, hepatitis B or C, other chronic liver diseases, or heavy alcohol use. Routine descriptive statistical measures were used. Survival distributions were estimated using Kaplan-Meier method, and Cox regression was used for multivariate analysis. Two-tailed p < 0.05 was considered significant.

Results

Eighty-six patients were included - all were females, median age was 57.5 years, and 90% were Caucasian; 86% of primary tumors were hormone-receptor positive and 17% were HER2 positive. Most patients (98%) had metastatic disease with liver involvement (94%), and were heavily pre-treated - 97% with chemotherapy, 85% with hormonal therapy, and 19% with anti-HER2 agents. Median interval from breast cancer diagnosis to pseudocirrhosis was 75.4 months (IQR 35.2-115.3 months). Thirty-six percentage of patients had ≥1 signs of portal hypertension and 49% had ≥1 signs of hepatocellular failure. Pseudocirrhosis led to permanent discontinuation of chemotherapy, endocrine therapy, and all systemic therapies in 29%, 31%, and 20% patients, respectively. Median overall survival from diagnosis of pseudocirrhosis was 10.0 months (95%CI 5.2-14.8 months). On multivariate analysis, coagulopathy, hyperbilirubinemia, hypoalbuminemia, and cancer progression were independently predictive of mortality.

Conclusions

In this largest series, to date, of breast cancer with pseudocirrhosis, the latter was often complicated by portal hypertension and hepatocellular failure, and markedly impacted breast cancer management. Survival was shorter for patients who developed hepatocellular failure.

Other types of diffuse liver disease: is there a way to do it?

There are a variety of less common diffuse liver diseases that can be asymptomatic or cause severe liver dysfunction. For the majority of them, the association of clinical, laboratory, and imaging findings are needed to narrow the differential diagnosis. In this article, we will review and describe the rarer diffuse liver diseases including drug-related liver disease, inflammatory and infectious diseases, and deposition disorders such as amyloidosis, glycogen storage disease, Wilson's disease, and alpha-1 antitrypsin deficiency. Abdominal radiologists should be familiar with the imaging features of different types of diffuse liver diseases to help the multidisciplinary team involved in the treatment of these patients. The data related to some of these conditions are scarce and sometimes experimental, but we want to demonstrate to the reader the value of imaging techniques in their analysis and introduce the potential of new imaging methods.
