Comprehensive Review of Clinical Presentation, Diagnosis, Management, and Prognosis of Ruptured Hepatocellular Carcinoma. J Gastrointest Surg 2024:S1091-255X(24)00458-X. [PMID: 38759880 DOI: 10.1016/j.gassur.2024.05.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 05/10/2024] [Accepted: 05/13/2024] [Indexed: 05/19/2024]
Abstract
INTRODUCTION Spontaneous rupture of hepatocellular carcinoma (rHCC) is a life-threatening complication occurring in 3-15% of patients with HCC. This review discusses the most recent updates in the epidemiology, pathophysiology, risk factors, diagnosis and presentation, management, and prognostic factors of rHCC. METHODS A comprehensive systematic review was performed using MEDLINE/PubMed and Web of Science databases, with the end of search date being December 1, 2023, regarding rHCC diagnosis, imaging, and management. RESULTS Achieving adequate hemostasis and stabilization of the patient remains the primary objective in managing patients presenting with rHCC. In earlier studies, the mortality rate in the acute phase of rHCC has been reported to be 25-75%. However, more recent studies reviewed here have demonstrated that transcatheter arterial embolization/chemoembolization (TAE/TACE) followed by elective hepatectomy in select patients may offer significantly improved survival benefits and decrease perioperative complications compared to TAE/TACE alone or emergent/one-stage hepatectomy. CONCLUSION Although prognosis for rHCC remains the lowest among causes of death related to HCC, more recent studies have demonstrated that improved short- and long-term patient outcomes may be achieved through active surveillance efforts for HCC combined with advanced multimodal diagnostic tools and multidisciplinary management strategies.

Abstract
We report a case of a life-threatening ruptured renal angiomyolipoma (AML) that did not meet the criteria for prophylactic treatment (tumor >4 cm or intratumoral aneurysm >5 mm) during follow-up. A woman in her 70s was followed up for a 2.5-cm AML with a rich vascular component. An intratumoral aneurysm >5 mm was not identified for 2 years. She complained of a sudden abdominal pain with hypotension, and contrast-enhanced computed tomography revealed a retroperitoneal hematoma with contrast media extravasation from an intratumoral aneurysm. Emergency transcatheter arterial embolization was successfully performed using N-butyl cyanoacrylate glue. Rupture can occur in small AMLs or in AMLs not identified with intratumoral aneurysms during follow-up. AMLs with a rich vascular component at the kidney surface are more likely to rupture.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors globally. Many complications are attributed to it, including spontaneous rupture, which is a serious and rare complication that can be life-threatening. Managing and detecting this condition might pose challenges, especially when there is no prior history of liver cirrhosis or tumor. We report on a 57-year-old man followed as an outpatient for chronic hepatitis C who presented to the emergency department for abdominal pain with abdominal distention and jaundice, occurring two months after treatment by direct-acting antiviral (DAA). He was not known to have a liver tumor on the ultrasound performed before the start of treatment. Therefore, the diagnosis of tumor rupture was not very clear. The evolution was fatal, and death occurred quickly. Although the association between DAA treatment and hepatocarcinogenesis and its possible complications is unknown, close monitoring by high-performance imaging is probably required in patients under DAA.

Abstract
Rupture of HCC (rHCC) is a life-threatening complication of hepatocellular carcinoma (HCC), and rHCC may lead to a high rate of peritoneal dissemination and affect survival negatively. Treatment for rHCC mainly includes emergency surgery, interventional therapies, and palliative treatment. However, the management of rHCC should be carefully evaluated. For patients with severe bleeding, who are not tolerant to open surgery, quick hemostatic methods such as rupture tissue ablation and TAE/TACE can be performed. We described clinical presentation, prognosis, complication, interventional management, and current evidence of rHCC from the perspective of interventional radiologists. Overall, our review summarized that interventional therapies are necessary for most patients with rHCC to achieve hemostasis, even in some patients with Child–Pugh C. Moreover, TAE/TACE followed by staged hepatectomy is a beneficial treatment for rHCC according to current clinical evidence. TAE/TACE is the first choice for most patients with rHCC, and appropriate interventional treatment may provide staged surgery opportunities for those who are not tolerant to emergency surgery to reach an ideal prognosis.

Abstract
Background Ruptured hepatocellular carcinoma (rHCC) is considered a rare and life-threatening manifestation; when it happens, it often requires acute and positive intervention. At present, the mechanism of rHCC development is gradually being understood while there are many kinds of rHCC treatment. From our clinical observation, the prognosis of rHCC patients is not as poor as it is currently believed. It may not be appropriate to include all patients with rHCC in T4. Main Body The incidence of ruptured hepatocellular carcinoma is now rising. Especially in the Asian region, it can even reach 10% – 15%. The most common symptom of HCC rupture is abdominal pain, and there are now a variety of treatments for hepatocellular carcinoma rupture. With aggressive treatment, rHCC patients can also achieve a better prognosis. The patient’s condition varies on admission, so the treatment methods will also be different. It is critical to identify prognostic factors simultaneously, and rHCC can be effectively managed by focusing on important prognostic factors. Conclusion A review was carried out to analyze diagnosis, mechanism, treatment, and prognostic risk factors on this disease condition during the current situation; it is hoped that it will provide better guidance for clinicians. Moreover, patients with rHCC were managed hierarchically to prolong their prognosis.

Rupture of Hepatocellular Carcinoma: A Review of Literature. J Clin Exp Hepatol 2019; 9:245-256.

Abstract
Approximately 700,000 people die of Hepatocellular Carcinoma (HCC) each year worldwide, making it the third leading cause of cancer related deaths. Rupture is a potentially life-threatening complication of HCC. The incidence of HCC rupture is higher in Asia and Africa than in Europe. In Asia approximately 10% of patients with a diagnosis of HCC die due to rupture each year. Spontaneous rupture is the third most common cause of death due to HCC after tumor progression and liver failure. The diagnosis of rupture in patients without history of cirrhosis or HCC may be difficult. The most common symptom of ruptured HCC is abdominal pain (66-100%). Shock at presentation can be seen in 33-90% of cases; abdominal distension is reported in 33%. Abdominal paracentesis documenting hemoperitoneum is a reliable test to provisionally diagnose rupture of HCC, it can be seen in up to 86% of clinically suspected cases. The diagnoses can be confirmed by computed tomography scan or ultrasonography, or both in 75% of cases. Careful pre-treatment evaluation is essential to decide the best treatment option. Management of ruptured HCC involves multi-disciplinary care where hemostasis remains a primary concern. Earlier studies have reported a mortality rate of 25-75% in the acute phase of ruptured HCC. However, recent studies have reported a significant decrease in the incidence of mortality. There is also a decrease in the incidence of ruptured HCC due to improved surveillance and early detection of HCC. Transarterial Embolization is the least invasive method to effectively induce hemostasis in the acute stage with a success rate of 53-100%. Hepatic resection in the other hand has the advantage of achieving hemostasis and in the same go offers a potentially curative resection in selected patients.

Abstract
Background Although secondary liver involvement of the lymphoma is common and occurs in 50% of patients with non-Hodgkin’s lymphoma, liver tumor rupture in malignant lymphoma is extremely rare. We report a case of a spontaneously ruptured secondary liver involvement of non-Hodgkin’s lymphoma that was successfully treated with transcatheter arterial embolization (TAE) to obtain hemostasis, and subsequent hepatectomy and systemic chemotherapy. To the best of our knowledge, this is only the second reported case of a ruptured hepatic lymphoma. Case presentation A 74-year-old man with sudden-onset right shoulder and upper quadrant pain was transferred to our hospital via an ambulance. His vital signs were stable. Contrast-enhanced computed tomography showed a large hypo-enhancing tumor (94 × 81 mm) in the posterior segment of the liver, with intratumoral extravasation and a 12 × 10 mm daughter tumor in segment 5 of the liver. Hemoperitoneum due to rupture of hepatocellular carcinoma with intratumoral hemorrhage was suspected, although the serum alpha-fetoprotein and protein induced by vitamin K absence-II levels were within normal range. TAE was used for hemostasis. Extended posterior segmentectomy including tumor resection in segment 5 was performed on day 23 after embolization. The postoperative course was uneventful. Pathological examination of the resected specimens revealed that the ruptured tumor was diffuse large B-cell lymphoma. Postoperative fluorodeoxyglucose positron emission tomography-computed tomography showed uptake in the left parotid gland, pancreas, and thoracic vertebra. Based on these findings, the final diagnosis was a ruptured secondary hepatic malignant lymphoma. Complete remission was achieved with chemotherapy. He remains alive 30 months after hepatectomy without evidence of relapse. Conclusions We report the first case describing a hepatic tumor rupture as the first presentation of a primary or secondary hepatic malignant lymphoma. The patient was successfully treated with TAE, hepatectomy, and subsequent systemic chemotherapy for non-Hodgkin’s lymphoma.

Abstract
Background A ruptured hepatocellular carcinoma (HCC) is often fatal. In addition to surgery and transarterial embolization, radiofrequency ablation (RFA) might be another option for treating a ruptured HCC. Unfortunately, conventional RFA has a limited ablation zone; as such, it is rarely used to treat ruptured tumors. Case presentation This case was a 60-year-old man who had a large, ruptured HCC in which hydrochloric acid (HCl)-enhanced RFA successfully controlled the bleeding and made the tumor completely necrotic. Conclusion Considering the effectiveness of HCl-enhanced RFA in achieving hemostasis and tumor ablation, it might be a new option for treating large, ruptured HCCs.

Abstract
Hemoperitoneum due to spontaneous rupture of hepatocellular carcinoma is a life-threatening and rare condition in western countries with an incidence of less than 3% because of early detection of cirrhosis and neoplasm. Here, we describe a case of a 66-year-old male patient with altered mental status with hemorrhagic shock. Computed tomography scan of abdomen revealed hemoperitoneum and mass in liver. Patient underwent resection of liver tumor and biopsy revealed multinodular hepatocellular carcinoma. A high degree of suspicion is required where severe anemia and hemoperitoneum can be a first presentation for hepatocellular carcinoma especially in patients with chronic hepatitis C infection. Early diagnosis is crucial since mortality rates remain high for untreated cases.

Abstract
The incidence of hepatocellular carcinoma (HCC) is rising worldwide. Spontaneous rupture of HCC occasionally occurs, and ruptured HCC with intraperitoneal hemorrhage is potentially life-threatening. The most common symptom of ruptured HCC is acute abdominal pain. The tumor size in ruptured HCC is significantly greater than that in non-ruptured HCC, and HCC protrudes beyond the original liver margin. In the acute phase, hemostasis is the primary concern and tumor treatment is secondary. Transcatheter arterial embolization (TAE) can effectively induce hemostasis. The hemostatic success rate of TAE ranges 53-100%. A one-stage surgical operation is a treatment modality for selected patients. Conservative treatment is usually given to patients in a moribund state with inoperable tumors and thus has poor outcomes. Patients with severe ruptures of advanced HCC and poor liver function have high mortality rates. Liver failure occurs in 12-42% of patients during the acute phase. In the stable phase, tumor treatment, such as transarterial chemoembolization or hepatic resection should be concerned. The combination of acute hemorrhage and cancer in patients with ruptured HCC requires a two-step therapeutic approach. TAE followed by elective hepatectomy is considered an effective strategy for patients with ruptured HCC.

Abstract
BACKGROUND A spontaneous hepatic haemorrhage (SHH) is a rare condition that presents acutely to both hepatobiliary and general surgeons. Management of the condition is challenging because of the emergent presentation requiring immediate intervention, the presence of underlying chronic liver disease and the multiple potential underlying aetiological conditions. METHODS A literature search on a spontaneous hepatic haemorrhage was instituted on Medline (1966-2014), Cochrane Register of Controlled Trials, EMBASE (1947-2014), PubMed, Web of Science and Google Scholar. The specific topics of interest were causes - including rare causes, pathophysiological mechanisms and management options. A narrative review was planned from the outset. RESULTS After 1546 abstracts were reviewed, 74 studies were chosen for inclusion. Hepatocellular carcinoma (HCC) is the commonest cause of a spontaneous haemorrhage with 10% of HCC presenting with bleeding. Other causes are benign hepatic lesions (hemangioma, adenoma, focal nodular hyperplasia, nodular regenerative hyperplasia, biliary cystadenoma and angiomyelolipoma), malignant hepatic tumours (angiosarcoma, haemangioendothelioma, hepatoblastoma and rhabdoid sarcoma), peliosis hepatis, amyloid, systemic lupus erythematosis, polyarteritis nodosa, HELLP syndrome and acute fatty liver of pregnancy. Treatment practice emphasizes arterial embolization to obtain haemostasis with a hepatectomy reserved for tumour-bearing patients after staging and assessment of liver function. CONCLUSION A spontaneous hepatic haemorrhage is an acute presentation of a spectrum of conditions that requires early diagnosis and multidisciplinary management.

Abstract
The identification of bleeding sites of ruptured hepatocellular carcinoma (HCC) is important for immediate treatment. We experienced a case of ruptured HCC readily treated with transarterial embolization (TAE) after identification of the bleeding site using contrast-enhanced ultrasonography (CEUS) with Sonazoid. We report the case of a 61-year-old male with multiple HCCs caused by alcohol-related cirrhosis, who was admitted for rapid development of abdominal fullness. The diagnosis was established by hemorrhagic ascites by abdominal paracentesis. No clear extravasation was found on contrast-enhanced computed tomography. CEUS using the re-injection method in the post-vascular phase showed active bleeding from a lesion close to the S5 gallbladder bed. Abdominal angiography was urgently performed. Based on CEUS findings, selective cannulation of the cystic artery was performed. Cystic angiography findings with carbon dioxide showed extravasation. He was treated by TAE. Our case had multiple HCCs, but CEUS was useful for the identification of bleeding sites.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is often diagnosed late because of the lack of pathognomonic symptoms. This study evaluated outcomes following liver resection (LR) for patients with HCC presenting with large tumor size (over 10 cm), adjacent organ invasion, or ruptured tumor, which we termed as complicated HCC (cHCC). MATERIALS AND METHODS We retrospectively reviewed 660 HCC patients who underwent LR between January 2001 and July 2005. The patients were grouped into cHCC and non-cHCC according to the defined criteria. The clinicopathological features were analyzed and compared between the two groups. RESULTS Patients in the cHCC group required longer operative times and resulted in greater intraoperative blood loss and more severe surgical complications. The cHCC group had a higher incidence of HCC recurrence after LR, and the HCC recurrence had a tendency to be associated with extrahepatic metastasis. The 5-year RFS (P < 0.0001) and OS (P < 0.0001) of cHCC and non-cHCC patients were 18.5% and 28.9% versus 37.5% and 57.6%, respectively. CONCLUSIONS LR for cHCC can be a great challenge for liver surgeons. However, with comparable operative mortality rates and acceptable survival times, surgical resection should always be considered performing in patients with cHCC, if clinically feasible.

Abstract
OBJECTIVE To provide an overview of recent studies on transarterial chemoembolization-related hepatic and biliary damage (TRHBD) in patients with malignant hepatic tumors (MHT) and to explore the reasons for TRHBD. METHODS Literature on the treatments for MHT by TACE was sought in PubMed and the related information was summarized. RESULTS TRHBD is found to occur in the hepatic parenchymal cells, biliary tree and blood-vascular system. The damage is mainly due to ischemia resulting from embolic materials such as gelatin sponge and lipiodol. In addition, clinicians' skill levels in non-superselective catheterization, the health condition of the patients, and the chemical agents used may also be related to the damage. Most of the deterioration can be reversed if the patients are diagnosed and treated properly and promptly. CONCLUSIONS Understanding the mechanisms of TRHBD more comprehensively is helpful in developing effective methods for prevention and treatment.

Abstract
AIM: To assess the treatment and tumor-related variables associated with outcome after treatment of spontaneously ruptured hepatocellular carcinoma (HCC).
METHODS: Patients with ruptured HCC were identified. The complications, mortality and survival were assessed. The relationship between tumor size and the severity of hemoperitoneum and between tumor size and grade were examined.
RESULTS: From January 1993 to January 2008, 556 patients with HCC with or without cirrhosis were evaluated; of which, 16 (2.87%) presented with spontaneous rupture. All but 1 patient had cirrhosis. Twelve patients underwent surgical resection while 4 underwent trans-cutaneous arterial catheter embolization (TAE) (trans-cutaneous arterial embolization). Early mortality (< 30 d) was 25% (4 of 16) and was inversely related to Child-Pugh score; 3 of the 4 early deaths occurred in patients treated with TAE with 1 of 12 occurring in the resected group. There was no correlation between tumor size and grade or between size and severity of hemoperitoneum.
CONCLUSION: Tumor size did not correlate with severity of the hemoperitoneum. There was an inverse relationship between G1-G3 (grade of cellular differentiation) HCC and dimensions.

Abstract
Hepatocellular carcinoma (HCC) has a tendency to rupture spontaneously which leads to a life-threatening condition. Disruption of the tumor surface or a tear in a parasitic feeding artery can cause HCC rupture leading to hemoperitoneum. When evaluating patients with a ruptured HCC, CT can detect tumors, determine tumor extent, define the presence of tumor bleeding, and show serial hematoma density changes. Thus, familiarity with the various CT findings of ruptured HCCs is essential to ensure proper diagnosis and treatment. In this pictorial essay, the authors illustrate the usual and unusual manifestations of ruptured HCCs, as visualized by CT, and include some angiographic correlations. CT findings predictive of HCC rupture are also discussed.

Abstract
Rupture of hepatocellular carcinoma (HCC) is a life-threatening complication. Peritoneal metastasis of HCC after spontaneous rupture was seldom noted. We report a case of intraperitoneal metastasis of HCC after spontaneous rupture. A previously asymptomatic 72-year-old man was admitted due to dull abdominal pain with abdominal fullness. He had a history of HCC rupture 10 mo ago and transarterial embolization was performed at that time. Abdominal computer tomography (CT) scan showed a huge peritoneal mass over the right upper quadrant area. Surgical resection was arranged and subsequent microscopic examination confirmed a diagnosis of moderately-differentiated HCC.

Abstract
Hemoperitoneum may occur in various emergent conditions. In the trauma setting, evidence of intraperitoneal blood depicted at computed tomography (CT) should lead the radiologist to conduct a careful search of images for the injured visceral organ (the liver or spleen). Specific CT signs, such as a sentinel clot or extravasation of intravascular contrast material, may indicate the source of bleeding and help direct management. In addition, the configuration of accumulated blood may help identify the injured organ; for example, triangular fluid collections are observed in the mesentery most often in the setting of bowel or mesenteric injury. Less commonly, hemoperitoneum may have a nontraumatic origin. Iatrogenic hemoperitoneum may occur as a complication of surgery or other interventional procedures in the abdominal cavity or as a result of anticoagulation therapy. Hemoperitoneum also may be seen in the setting of blood dyscrasias such as hemophilia and polycythemia vera. Tumor-associated hemorrhage, which most often occurs in hepatocellular carcinoma, hepatic adenoma, or vascular metastatic disease, also may produce hemoperitoneum. Other potential causes of nontraumatic hemoperitoneum are gynecologic conditions such as hemorrhage or rupture of an ovarian cyst and rupture of the gestational sac in ectopic pregnancy, and hepatic hematoma in syndromic hemolysis with elevated liver enzymes and low platelet count (HELLP syndrome). Vascular lesions (visceral artery aneurysms and pseudoaneurysms) that occur in systemic vascular diseases such as Ehlers-Danlos syndrome or in pancreatitis are another less common source of hemoperitoneum.

Abstract
O objetivo deste trabalho foi descrever e ilustrar aspectos incomuns do hepatocarcinoma na tomografia computadorizada e ressonância magnética. A partir da análise retrospectiva de 100 casos de pacientes com hepatocarcinoma diagnosticado por análise combinada de exames de imagem, dosagem de alfa-feto-proteína, biópsia percutânea ou ressecção cirúrgica, selecionamos aqueles com apresentação atípica em um ou mais métodos de imagem ou aqueles com evolução não usual, ilustrando os seus principais aspectos de imagem. Entre os casos apresentados, escolhemos pacientes com hepatocarcinomas císticos, hemorrágicos, rotos e causando hemoperitônio, calcificados, com regressão espontânea, exofíticos, hipovasculares, gigantes e com disseminação não usual. O hepatocarcinoma é o tumor maligno mais comum do fígado e freqüentemente tem apresentação típica e associada à cirrose hepática. Porém, em alguns casos, apresentações atípicas podem retardar o seu diagnóstico.

Abstract
Spontaneous intraperitoneal bleeding can result from a vast array of etiologies. Fortunately, most are uncommon and currently available imaging modalities can be used to differentiate them in almost all cases. Meticulous imaging technique and careful observation of key imaging features are important for accurate characterization of the organ of origin of the spontaneous bleeding. CT is the single most important imaging technique in the detection and characterization of spontaneous intraperitoneal bleeding. Further development in multidetector technology, such as the introduction of new machines with 8 or 16 detectors, should improve the effectiveness of CT further. Sonography and MR imaging are complimentary to CT, especially in patients with pelvic abnormalities or equivocal CT findings.

Abstract
A variety of high-resolution imaging techniques are currently available for the evaluation of patients with RUQ pain. In these patients, an imaging approach that is based on identifying the presence of certain clinical signs and symptoms can aid in choosing the appropriate imaging modality and establishing the diagnosis. For patients presenting with a positive Murphy sign, sonography and biliary scintigraphy are the most useful initial imaging techniques. In patients with fever and a negative Murphy sign, a combination of sonography and contrast-enhanced CT can establish the diagnosis in most cases. And finally, in patients without fever or a positive Murphy sign, CT and MR are appropriate first-line imaging techniques.

Abstract
To evaluate the helical CT findings of ruptured hepatocellular carcinoma (HCC), 12 patients with ruptured HCC were reviewed with regard to the tumour's location, size and contour protrusion, the appearance of the mass, the enhancement pattern, multiplicity and secondary changes. All ruptured tumours were located at the periphery of the liver and had a protruding contour. The maximum diameter of tumours ranged from 2 cm to 16 cm. Discontinuity of the hepatic surface was seen in 11 cases. In eight cases, CT images during the arterial phase showed a non-enhancing low attenuating lesion with focal discontinuity and peripheral rim enhancement. Seven cases showed separation of tumour content from the peripheral enhancing rim and intraperitoneal rupture of tumour content into the perihepatic space. Because of the similar appearance to an enucleated orbital globe with remaining sclera, this was termed the "enucleation sign". As well as ruptured masses, 10 cases with non-ruptured masses also showed a non-enhancing low attenuating pattern. Seven cases showed a haematoma with high attenuation around the ruptured mass. The peripheral location, protruding contour, discontinuity of the hepatic surface and surrounding haematoma are helpful signs in the diagnosis of ruptured HCC. The "enucleation sign" may be a characteristic finding in ruptured HCC.

Abstract
Spontaneous hepatic bleeding is a rare condition. In the absence of trauma or anticoagulant therapy, hepatic hemorrhage may be due to underlying liver disease. The most common causes of nontraumatic hepatic hemorrhage are hepatocellular carcinoma and hepatic adenoma. Such hemorrhage can also occur in patients with other liver tumors, such as focal nodular hyperplasia, hemangiomas, and metastases. Other conditions associated with this entity include HELLP syndrome, amyloidosis, and miscellaneous causes. Imaging plays a significant role in the diagnosis and management of this potentially lethal entity. In the appropriate clinical setting, the diagnosis of a hemorrhagic liver lesion is suggested when a hyperechoic mass or a mass with hyperechoic areas is seen at ultrasonography, a hyperattenuating mass is seen at computed tomography (CT), or a mass with high-signal-intensity areas is seen at T1-weighted magnetic resonance (MR) imaging. The signal intensity of blood can be increased or decreased on MR images depending on when the hemorrhage is imaged. The presence and extent of commonly associated subcapsular hematomas and hemoperitoneum can be easily ascertained with CT. During the first 24-72 hours, acute hematomas are hyperattenuating on nonenhanced CT scans; later, they decrease in attenuation and sometimes develop a pseudocapsule.

Abstract
BACKGROUND Transarterial oily chemoembolization (TOCE) is frequently employed as a non-operative treatment for hepatocellular carcinoma (HCC). Serious complications of TOCE are well known but ruptured HCC as a fatal complication of TOCE has not been reported previously. METHODS A retrospective study was performed on all patients who received TOCE for treatment of HCC from January 1989 to October 1996; the complication of ruptured HCC within 2 weeks from the procedure was recorded. RESULTS During the study period, 391 patients received a total of 1443 sessions of TOCE (mean 3.7 sessions per patient) for the treatment of HCC, with an overall median survival of 10.4 months. Six patients developed ruptured tumour within 2 weeks after TOCE, resulting in an overall incidence of 1.5 per cent per patient or 0.4 per cent per procedure. All except one patient died 1-25 days after tumour rupture. Factors common to these six patients included: (1) male sex; (2) large tumour size (range 8-17 cm in diameter); (3) tumour located in the right lobe of the liver; (4) tumour ruptured after the first session of TOCE; and (5) TOCE performed as primary treatment without previous hepatic resection. CONCLUSION Ruptured HCC is a serious complication of TOCE although the incidence is low. It occurred predominantly in men after the first session of TOCE for a large irresectable tumour of the right lobe.

Abstract
Spontaneous rupture of hepatocellular carcinoma (HCC) is a life-threatening condition; the mechanism is not clear but it is suggested that rupture is usually preceded by rapid expansion of the tumour secondary to bleeding from within its substance. Diagnosis may be made by abdominal paracentesis, ultrasonography, computed tomography or angiography; the positive rates of diagnosis are 86, 66, 100 and 20 per cent respectively. Prognosis is poor. Based on treatment results reported in the literature, the mean survival time for patients who underwent hepatectomy, transcatheter arterial embolization (TAE) and conservative therapy were 247, 98 and 13 days respectively. Judging from the reported results the first choice for emergency treatment of haemostasis is TAE. If laparotomy is undertaken, hepatic artery ligation, preferably of the branch supplying the liver lobe bearing the tumour, should be considered, together with haemostasis of the rupture site by various means (suture plication, packing, argon beam coagulation, use of microwave or absolute ethanol). Emergency hepatectomy should be reserved for patients with an easily resectable lesion who are in a stable cardiovascular condition. Conservative therapy may be used for selected patients in extremely poor condition. The rational treatment for the majority of patients with ruptured HCC is TAE, followed by hepatectomy if the lesion is resectable.
