Hepatocellular carcinoma with direct invasion to the stomach

Hepatocellular Carcinoma with Gastrointestinal Involvement: A Systematic Review

In this paper, we aimed to evaluate clinical and imagistic features, and also to provide a diagnostic algorithm for patients presenting with gastrointestinal involvement from hepatocellular carcinoma (HCC). We conducted a systematic search on the PubMed, Scopus and Web of Science databases to identify and collect papers oncases of HCC with gastrointestinal involvement. This search was last updated on 29 April 2022. One hundred and twenty-three articles were included, corresponding to 197 patients. The majority of the patients were male (87.30%), with a mean age of 61.21 years old. The analysis showed large HCCs located mainly in the right hepatic lobe, and highly elevated alfa-fetoprotein (mean = 15,366.18 ng/mL). The most frequent etiological factor was hepatitis B virus (38.57%). Portal vein thrombosis was present in 27.91% of cases. HCC was previously treated in most cases by transarterial chemoembolization (32.99%) and surgical resection (28.93%). Gastrointestinal lesions, developed mainly through direct invasion and hematogenous routes, were predominantly detected in the stomach and duodenum in equal measure—27.91%. Gastrointestinal bleeding was the most common presentation (49.74%). The main diagnostic tools were esophagogastroduodenoscopy (EGD) and computed tomography. The mean survival time was 7.30 months. Gastrointestinal involvement in HCC should be included in the differential diagnosis of patients with underlying HCC and gastrointestinal manifestations or pathological findings in EGD.

Gastric Metastasis of Hepatocellular Carcinoma With Gastrointestinal Bleeding After Liver Transplant: A Case Report

Gastrointestinal (GI) metastasis of hepatocellular carcinoma is very rare. This is the first report of post-transplantation gastric metastasis. A 43-year-old man with a history of hepatitis B-related hepatocellular carcinoma (HCC) in the right anterior segment of the liver received an orthotopic liver transplant. Three months after the transplantation, pulmonary metastasis was found by chest computed tomography, and he received 1 course of gamma knife treatment. He complained of melena with anemia 17 months post liver transplantation. Abdominal CT scan showed new occupying lesions in the liver and a mass in the stomach and around the spleen with embolus in the splenic vein. Endoscopy revealed a large irregular cauliflower-like mass in fundus with ulceration and bleeding on the surface. He received symptomatic treatment, but died of cancer-related bleeding 4 months later. GI bleeding may due to gastric metastasis after liver transplantation.

Hepatocellular carcinoma with duodenal invasion and metastasis

BACKGROUND AND AIM

Hepatocellular carcinoma (HCC) is the leading cause of cancer-related deaths in Taiwan. HCC with duodenal involvement are rare and are associated with a poor prognosis. The purpose of this retrospective study was to collect clinical information and data regarding survival following various treatments.

METHODS

Between 1996 and 2009, 21 cases (17 men) were diagnosed with HCC and duodenal invasion and metastases by diagnostic imaging, endoscopy with biopsy, or surgically collected specimens sent to pathology. The clinical course was analyzed from the patients' medical records.

RESULTS

Gastrointestinal bleeding was reported in 18/21 patients. Diagnostic imaging showed that the majority of cases involved direct tumor invasion (predominantly from the right liver lobe) and six cases from metastasis. Tumor mass and ulcerations were the most common features noted on endoscopy. In addition to the component therapy and medication treatment, panendoscopic hemostasis, surgery, transcatheter arterial embolization, and radiotherapy were performed for the management of duodenal involvement and gastrointestinal bleeding. Survival duration after duodenal involvement ranged from 0.2 to 57.8 months (mean 10.5 months).

CONCLUSIONS

Gastrointestinal bleeding in advanced HCC should raise suspicions of duodenal involvement. HCC can involve the duodenum by direct invasion (from either the left or right liver lobes) or metastasis. The prognosis for HCC patients with duodenal involvement is poor, but is improved by supportive care and application of various treatment modalities.

Long term survival in patients with hepatocellular carcinoma directly invading the gastrointestinal tract: case reports and literature review

Hepatocellular carcinoma (HCC) directly invading the gastrointestinal (GI) organs is rare and is associated with poor survival outcome. We report two patients with good long-term outcome following resection of HCC that invaded the stomach and duodenum, respectively. A literature review was conducted to elucidate the course of patients with this pathology. Two cases (57-year-old and 72-year-old males) with enlarged hepatic tumors directly invading the stomach and duodenum underwent hepatectomies with en-bloc resection of the involved organs. Both patients are still alive at 80 and 68 months following the surgery. Our literature review showed that most of the patients with this pathology have manifested, and died of persistent GI bleeding. Patients who were treated surgically had a statistically significant longer survival than those who were treated with non-surgical palliative treatments (P < 0.001). In addition, patients who were treated with surgery with curative intent tend to have a longer survival times than those who were treated with surgery to palliate the bleeding but the difference was not statistically significant (P < 0.174). Removing the tumor completely could significantly prolong the survival of patients with HCC invading the GI tract.
