Lower gastrointestinal bleeding from a hepatocellular carcinoma invading the colon

Massive and life-threatening upper gastrointestinal bleeding due to invasive hepatocellular carcinoma: A case report

•

Hepatocellular carcinoma (HCC), which constitutes more than 90% of primary liver cancers, is a major global health problem.

•

In HCC, 30% of cancer related deaths is due to hepatic failure, and 10% is due to gastrointestinal (GI) bleeding. GI metastasis is reported as 0.4-2%. GI bleeding frequency due to HCC direct invasion is 0.05-2%, and may be fatal.

•

Besides, the repetition of TAE, intra-arterial chemotherapy, radiotherapy, and individualized treatment plans have recently increased survival in unresectable HCC patients, and thus it is expected that GI involvement will be more commonly encountered in HCC patients in the near future.

Background

The mean survival is less than 6 months in hepatocellular carcinoma (HCC) patients with extrahepatic metastasis. Gastrointestinal(GI) bleeding frequency due to HCC invasion is 0.05% to 2.0%, and may be fatal.

Case presentation

We encountered a case of HCC with direct invasion to the gastrium that caused a life-threatening upper GI bleeding. Our patient was a 62 year old male who was a heavy smoker and drinker for almost 30 years. He had several upper GI bleeding episodes during the previous 6 months. Computed tomography (CT) revealed a 13 cm liver tumour directly invading the gastrium. Partial hepatic resection and subtotal gastrectomy were performed. Unfortunately, the patient died at the intensive care unit postoperatively due to hepatic failure.

Discussion

Although the prognosis of HCC that has invaded the gastrium is very poor due to the advanced stage of the disease, surgical resection may be a favourable treatment option for patients with a massive upper GI bleeding.

Conclusions

The incidence of patients with massive bleeding due to gastric invasion of HCC is low, and only a few cases have been reported in the literature. Our purpose while presenting this rare case is to increase the awareness about the issue.

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.

Massive upper gastrointestinal hemorrhage due to invasive hepatocellular carcinoma and hepato-gastric fistula

A 36-year-old male Asian immigrant with a history of hepatitis B and hepatitis C related unresectable hepatocellular carcinoma in the left lobe of the liver presented with hematemesis and severe anemia. He was diagnosed with a liver mass that was resected 8 years ago described as a benign tumor in his home country. He had received trans-arterial chemoembolization (TACE) four months ago after subsequent diagnosis of unresectable hepatoma, and currently was receiving chemotherapy with Sorafenib. After resuscitation, a contrast enhanced computerized tomography was performed which showed fistulization of hepatocellular carcinoma into adjacent stomach. This finding was confirmed during endoscopy with direct visualization of the fistulous opening. Hepatocellular carcinoma (HCC) invading the gastrointestinal (GI) tract is rare. We present a case and literature review of HCC with local invasion of the stomach causing massive upper GI bleeding after receiving TACE.

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.

Endoscopic treatment of duodenal bleeding caused by direct hepatocellular carcinoma invasion with an ethanol injection

We report a case of a man who developed duodenal bleeding caused by direct hepatocellular carcinoma (HCC) invasion, which was successfully treated with endoscopic ethanol injection. A 57-year-old man with known HCC was admitted for melena and exertional dyspnea. He had been diagnosed with inoperable HCC a year ago. Urgent esophagogastroduodenoscopy (EGD) showed two widely eroded mucosal lesions with irregularly shaped luminal protruding hard mass on the duodenal bulb. Argon plasma coagulation and Epinephrine injection failed to control bleeding. We injected ethanol via endoscopy to control bleeding two times with 14 cc and 15 cc separately without complication. Follow-up EGD catched a large ulcer with necrotic and sclerotic base but no bleeding evidence was present. He was discharged and he did relatively well during the following periods. In conclusion, Endoscopic ethanol injection can be used as a significantly effective and safe therapeutic tool in gastrointestinal tract bleeding caused by HCC invasion.

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.

Hepatogastric fistula caused by direct invasion of hepatocellular carcinoma after transarterial chemoembolization and radiotherapy

A 63-year-old man with a history of hepatitis-B-related hepatocellular carcinoma (HCC) in the left lateral portion of the liver received repeated transcatheter arterial chemoembolization (TACE) and salvage radiotherapy. Two months after completing radiotherapy, he presented with dysphagia, epigastric pain, and a protruding abdominal mass. Computed tomography showed that the bulging mass was directly invading the adjacent stomach. Endoscopy revealed a fistula from the HCC invading the stomach. Although the size of the mass had decreased with the drainage through the fistula, and his symptoms had gradually improved, he died of cancer-related bleeding and hepatic failure. This represents a case in which an HCC invaded the stomach and caused a hepatogastric fistula after repeated TACE and salvage radiotherapy.

Successful en bloc resection of primary hepatocellular carcinoma directly invading the stomach and pancreas

Multivisceral surgical resection for cure was successfully performed in a 70-year-old man suffering from a primary hepatocellular carcinoma (HCC) associated with direct invasion to the stomach and pancreas. The patient presented with gastric outlet obstruction, upper abdominal pain and a history of chronic liver disease due to hepatitis B virus (HBV) infection. Upper gastrointestinal (GI) endoscopy revealed an infiltrating tumor protruding through the gastric wall and obliterating the lumen. Computer tomograghy (CT) and magnetic resonance imaging (MRI) scan demonstrated a 15-cm tumor in the left lateral segment of the liver with invasion to the stomach and pancreas. Alpha-foetoprotein (AFP) levels and liver function tests were normal. The patient underwent an en bloc left hepatectomy, total gastrectomy, distal pancreatectomy with splenectomy and radical lymphadenectomy. Pathology revealed a poorly differentiated, giant cell HCC involving the stomach and pancreas. Disease-free margins of resection were achieved. The patient’s postoperative course was uneventful. Sixteen months after surgery, he has no recurrence or distal metastasis. Direct invasion of HCC into the GI tract is rarely encountered. Complete surgical resection should be considered in selected patients with an appropriate hepatic functional reserve.

Direct invasion to the colon by hepatocellular carcinoma: Report of two cases

Although hepatocellular carcinoma (HCC) is a common tumor, direct invasion of the gastrointestinal tract by HCC is uncommon. Recently, we encountered two cases of HCC with direct invasion to the colon. The first patient was a 79-year-old man who underwent transarterial chemo-embolization (TACE) for HCC 1.5 years prior to admission to our hospital. Computed tomography (CT) showed a 7.5-cm liver tumor directly invading the transverse colon. Partial resection of the liver and transverse colon was performed. The patient survived 6 mo after surgery, but died of recurrent HCC. The second patient was a 69-year-old man who underwent TACE and ablation for HCC 2 years and 7 months prior to being admitted to our hospital for melena and abdominal distension. CT revealed a 6-cm liver tumor with direct invasion to the colon. The patient underwent partial resection of the liver and right hemicolectomy. The patient recovered from the surgery. But, unfortunately, he died of liver failure due to liver cirrhosis one month later. Although the prognosis of HCC that has invaded the colon is generally poor due to the advanced stage of the disease, surgical resection may be a favorable treatment option in patients with a good general condition.

Hepatocellular carcinoma with direct invasion to the stomach

A 71-year-old man was admitted to our hospital with abdominal pain. Hepatocellular carcinoma (HCC) had been diagnosed 2 years earlier and he had undergone 7 courses of intra-hepato-arterial chemotherapy (IHAC). We performed gastrointestinal fiberscopy and identified a massive protrusion on the lesser curvature. Abdominal contrast-enhanced computed tomography revealed multiple hepatic masses and an extrahepatic enlarged mass with invasion to the pancreas and stomach. A specimen for endoscopic biopsy revealed adenocarcinoma that stained positive for alpha-fetoprotein. Gastrointestinal bleeding resulting from direct invasion of HCC is unusual.

Les tumeurs du colon transverse

Carcinoma of the transverse colon accounts for 10% of all colorectal cancer. Diagnosis is often delayed and complicated forms (perforation, fistulization, obstruction) occur in 30-50% of cases. The progression of symptoms is often insidious and tumors may be voluminous by the time of diagnosis. Right sided tumors are typically bulky and late-stage; perforation may lead to abdominal wall or retroperitoneal abscess. Tumor can also extend or fistulize into adjacent organs. Distal transverse cancers may be small annular lesions which are prone to obstruction. Cancers present as T4 lesions in 20-40% of cases. Abdominal CT is the best test to evaluate the loco-regional extension of advanced tumors. Their central location and advanced stage at presentation results in an extensive differential diagnosis. This central location also poses difficult surgical choices for lymph node dissection, extent of resection, and re-establishment of intestinal continuity. Surgical series which focus on transverse colon cancer date from the 1970-80's; they show curative resections in only 50% with morbidity/mortality of 20% and a global five year survival of less than 35%; they were considered to have a particularly poor prognosis.
