Combined Neuroendocrine Carcinoma and Hepatocellular Carcinoma of the Liver: Systematic Literature Review Suggests Implementing Biological Characterization to Optimize Therapeutic Strategy. Cancers (Basel) 2025; 17:1074. [PMID: 40227579 PMCID: PMC11988019 DOI: 10.3390/cancers17071074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2025] [Revised: 03/11/2025] [Accepted: 03/19/2025] [Indexed: 04/15/2025] Open
Abstract
BACKGROUND Mixed neuroendocrine-non-neuroendocrine tumors (MINEN) of the liver are exceptionally rare, with limited data available regarding their clinical behavior, pathogenesis, and optimal management. The coexistence of hepatocellular carcinoma (HCC) and neuroendocrine carcinoma (NEC) within the liver presents diagnostic and therapeutic challenges. METHODS A systematic literature search was conducted on PubMed, identifying cases of primary mixed HCC and NEC in the liver. The search adhered to PRISMA guidelines, and relevant studies were critically analyzed. A total of 45 documented cases were reviewed, focusing on patient demographics, clinical characteristics, treatment strategies, and outcomes. RESULTS Most patients (90%) were male, with a median age of 66.5 years. Hepatitis B or C infection was present in 74% of cases, and liver cirrhosis was reported in 38%. The combined type was the most frequently observed histological pattern (65%). Treatment modalities varied, including transarterial chemoembolization (TACE), radiofrequency ablation (RFA), surgery, and systemic therapies. The median overall survival was 10 months, highlighting the aggressive nature of these tumors. CONCLUSIONS Given the rarity and poor prognosis of hepatic MINEN tumors, multidisciplinary management is essential. Advanced molecular profiling may offer insights into tumor biology and potential therapeutic targets. Future research should explore novel systemic therapies, including immune checkpoint inhibitors, to improve patient outcomes.

Abstract
OBJECTIVE To highlight two cases mixed neuroendocrine non-neuroendocrine tumors (MINEN) of the liver and to review the literature till date. To present two cases of MINEN of the liver diagnosed in our centre with clinical & diagnostic workup, the treatment modalities, and follow up. Extensive review of the literature and compilation of the presentation and treatment modalities used in those cases. CASE REPORTS Thirty-three cases of MINEN of the liver have been reported till date including ours. Our cases presented as incidental masses in liver during workup for other symptoms. AFP levels were normal in both cases but PIVKA (Protein induced by vitamin K absence) levels were increased. Resection was done in one of the cases while the other patient had to undergo transplantation. A diagnosis of MINEN was made on H&E, and confirmed on IHC. One patient was unfit for systemic chemotherapy whereas the other patient received cisplastin and etoposide based chemotherapy. Both patients developed metastasis on follow up but are still alive after 12-15 months. CONCLUSION MINEN is an uncommon tumor of the liver with a poor prognosis as shown by the few studies available. Recurrence and distant metastases are often described even after complete resection and the course is fatal. The role of adjuvant chemotherapy following surgical resection is not fully elucidated. Mean survival in the cases reported ranged from 1 month to 33 months. However, no significant differences were seen in the clinicopathologic profile of the cases described so far. Further multiinstitutional studies and follow up will help to further characterize this subtype for appropriate treatment.

Abstract
Background Cases of large-cell neuroendocrine carcinoma (NEC) concomitant hepatocellular carcinoma (HCC) are very rare. Based on the microscopic characteristics, mixed HCC-NEC tumors can be divided into collision type and combined type. We report a patient with both collision and combined type HCC-NEC tumor at the same time. Case presentation A 58-year-old man with hepatitis B and cirrhosis was found to have two masses in segment 5 and segment 8 of the liver, respectively. Preoperative imaging diagnosis was primary liver cancer. Indocyanine green retention test (ICG R15) <10% suggested that the patient can tolerate surgery. Partial hepatectomy was performed under the guidance of 3D reconstruction. Postoperative pathology showed that most of the tumors in S5 were large-cell neuroendocrine carcinoma (90%), and a small part were hepatocellular carcinoma (10%). The tumor in S8 of the liver was diagnosed as HCC combined with immunohistochemistry. After surgery, the patient underwent genetic testing, which indicated mutations in TP53 gene. The test of immune markers of the sample suggest that the patient may benefit little from immune checkpoint inhibitor therapy. The cisplatin and etoposide chemotherapy protocol to the patient following their surgery. Eight month later after the operation, Enhanced CT showed there was no recurrence or metastasis of the tumor. Conclusion The case at hand augments the understanding of HCC-NEC mixed tumors, offering pivotal insights into their precise diagnosis and treatment modalities. Furthermore, we document a favorable prognosis, marked by an absence of recurrence signs thus far-a rarity in comparable instances. This enlightenment stands to facilitate the handling of ensuing cases and enhance patient prognoses.

Abstract
Mixed hepatocellular carcinoma with neuroendocrine carcinoma (HCC-NEC) is extremely rare, comprising about 0.46% of primary hepatic tumors. A 63-year-old man who was a chronic alcoholic presented with a nine-centimeter-sized hepatic mass. His serum alpha-fetoprotein and protein induced by vitamin K antagonist-II levels were 22,815 ng/mL and 183 mAU/mL, respectively. The patient underwent a right hemihepatectomy, including the middle hepatic vein. The tumor consisted of poorly differentiated HCC (20%) and large- and small-cell-type NEC (80%) components as per the pathological examination. Immunohistochemically chromogranin and synaptophysin were positive in the areas of NEC and negative in the areas of HCC. Adjuvant chemotherapy with a combination of cisplatin and etoposide was administered after surgery. At postoperative 5 months, the patient complained of right flank pain, and CT showed a new mass measuring 7.3 cm in the right adrenal gland. Postoperatively, after 6.5 months, more recurred masses were noted on the posterior aspect of the right kidney and both lungs. Although the regimen was changed from etoposide to irinotecan, additional recurred masses were developed in the liver, lung, and brain. He passed away 12 months after the surgery. After reviewing and analyzing previous literature, the 1 and 2 year overall survival rates are 57.3 and 43.6%, respectively, and the 1 and 2 year disease-free survival rates are 36.2 and 29.0%, respectively. Mixed HCC-NEC is a very rare tumor, and the surgical outcome is poor.

Abstract
Primary hepatic neuroendocrine carcinomas (PHNECs) are extremely rare, with only about 90 cases having been reported in the English-language literature. Among all neuroendocrine neoplasms, primary hepatic neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs) are extremely rare, accounting for 0.3% of NETs and 0.28-0.46% of malignant liver tumors. Additionally, primary hepatic NECs occur infrequently. The clinical diagnosis of primary hepatic NEC remains challenging because of its rarity and the lack of information about its characteristic appearance on images. Consequently, pathological examination through the performance of a preoperative liver tumor biopsy is essential for diagnosis. Due to the lack of availability of substantial high-quality data, there is no standard therapy for primary hepatic NEC. We present the first case of PHNEC metastasized to the mesentery reported in the English-language literature.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) can occasionally develop with other non-HCC cell types, either in a combined type or collision type. A collision tumor is defined as two histopathologically distinct tumors of the same organ lacking a clear transition zone. Hepatic collision tumors are rare. Among them, “hepatocellular carcinoma-hepatic neuroendocrine carcinoma” (HCC-NEC) collision tumors are especially rare and information about them is rarely published.
CASE SUMMARY A 48-year-old man with typical findings of HCC underwent consecutive therapies, including radiofrequency ablation and embolization prior to resection. Diagnosis of the HCC-NEC collision tumor in the right liver and another HCC in the left liver was established following surgical resection. The patient displayed NEC metastasis following resection and succumbed to septicemia after 2 more rounds of chemotherapy. To our knowledge, this is the 25th reported case of mixed HCC-NEC tumor. The rarity of HCC-NEC collision tumors and the absence of diagnostic criteria make it difficult to differentiate this condition from simple liver tumors, especially in patients with chronic liver disease.
CONCLUSION Our case highlights the difficulty in accurately diagnosing HCC-NEC in the absence of histological evidence. The prognosis is poor for this condition, although ultrasound-guided liver biopsy can be helpful to establish a prompt diagnosis. Further accumulation of such cases could help establish an accurate diagnosis earlier. Early discovery of NEC may allow for better treatment strategies and better prognoses.

Abstract
Background Primary hepatic neuroendocrine carcinomas (NECs) are extremely rare. The rate of recurrence after resection is extremely high, and the prognosis is poor. It is debatable whether chemotherapy or surgical resection is the optimal initial treatment for primary hepatic NECs. Therefore, selecting an appropriate therapeutic approach for patients with primary hepatic NECs remains clinically challenging. We present a case of primary hepatic NEC in a patient who developed recurrence after undergoing surgical resection. Case presentation A 78-year-old man with bone metastases of prostate cancer was referred to our department because of a solitary 66-mm tumor in the left lateral segment of the liver, which was detected on annual follow-up by computed tomography after prostate resection. A biopsy and preoperative diagnostic workup identified the lesion as a primary hepatic neuroendocrine carcinoma; therefore, left lateral segmentectomy was performed. Immunohistochemically, the tumor was positive for chromogranin A, synaptophysin, and CD 56, and the Ki-67 index was 40%. This neuroendocrine carcinoma was classified as a large cell type. Adjuvant chemotherapy with carboplatin + etoposide was initially administered a month after surgery. However, lymph node recurrence occurred 4 months after surgery, and the patient died of systemic metastases 15 months after surgical resection. Conclusions Due to the lack of availability of abundant quantities of relevant, high-quality data, there is no standard therapy for primary hepatic NECs. Selecting the most appropriate treatment for patients depending on several factors, such as the stage and differentiation of a tumor and a patient’s performance status and clinical course, is consequently preferred. More cases need to be studied to establish the best treatment strategy for primary hepatic NEC.

Abstract
Background: Neuroendocrine tumors are heterogeneous malignancies that originate from the neuroendocrine system. Previous studies show that this cancer type mainly localizes in the gastrointestinal tract and often metastasizes to the liver. Primary liver neuroendocrine tumors are very rare and primary hepatic neuroendocrine tumors (PHNET) with concurrent hepatocellular carcinoma (HCC) are extremely rare. To the best of our knowledge, only few PHNET cases have been identified, making their diagnosis difficult. Here, we report the biggest ever reported and “deceiving” lesion of a mixed neuroendocrine-non-neuroendocrine neoplasm in the liver, aiming to raise awareness and improve treatment of the disease. Case Presentation: Here, we report a preoperative misdiagnosed case that presented with hepatocellular carcinoma clinical features and no extrahepatic tumors. Postoperative pathology confirmed that it was a mixed neuroendocrine-non-neuroendocrine neoplasm. The patient was then referred for etoposide and cisplatin-based chemotherapy. No disease recurrence was observed at the 6-month follow-up. Conclusion: We report a very rare and easily misdiagnosed case and we speculate that there were “undifferentiated cells” undergoing neuroendocrine and hepatocellular carcinoma differentiation, during which some hepatocellular carcinoma cells express neuroendocrine features. We recommend proper surgery and postoperative platinum-based chemotherapy in the management of this disease.

Abstract
Background Hepatocellular carcinoma (HCC) can grow in a mosaic pattern, often combined with various non-hepatocellular cells. However, HCC combined with a neuroendocrine carcinoma (NEC) component is rarely reported, and its clinical features, origin, diagnosis, and behavior have not been established. In the literature, mixed HCC–NEC tumors are categorized as either collision type or combined type, depending on their microscopic features. Here, we report a patient with a combined-type HCC–NEC tumor. Case presentation An asymptomatic 84-year-old woman was found to have a solid mass in the right lobe of the liver. Laboratory and radiologic examinations showed typical findings of HCC, including arterial-phase enhancement, and portal- and delay-phase washout. She was treated by partial laparoscopic hepatectomy of segment 5. Pathological examination showed that the tumor was predominantly HCC, partly admixed with an NEC component. A transitional zone between the HCC and NEC tissues was also observed. The tumor was finally diagnosed as a combined-type primary mixed NEC–HCC tumor. After the preoperative diagnosis, the patient underwent somatostatin receptor scintigraphy to detect the primary NEC lesion, but no accumulation was found in any other part of her body. She has been free of recurrence for 9 months since the surgery. Conclusion Mixed HCC–NEC tumors are extremely rare, and correct diagnosis requires multidisciplinary collaboration. The accumulation of further cases is needed to help understand the exact pathology, diagnosis, and treatment of this disease.

Abstract
INTRODUCTION Although primary hepatic neuroendocrine carcinomas, whose prognostic mechanisms remain unclear, are rare, coexistence of neuroendocrine carcinomas and other tumors is rarer. In this report, we describe a unique case of coexistence between primary hepatic neuroendocrine carcinoma and a distal cholangiocarcinoma in the pancreas. PATIENT CONCERNS A 64-year-old woman with a history of diabetes, but none of hepatitis, was admitted to hospital because of intermittent epigastric distension and pain discomfort for more than 1 month aggravated 1 day. A contrast-enhanced computed tomography (CT) scan of the upper abdomen and abdominal magnetic resonance imaging (MRI) revealed a thickening of the bile duct wall in the middle and lower segment of common bile duct and the corresponding lumen is narrow and low-density tumors with ring enhancement (1.83 cm × 1.9 cm) in lobi hepatis dexte. DIAGNOSIS Primary neuroendocrine carcinoma of the liver was diagnosed to be coexisting with a distal cholangiocarcinoma, which had invaded the pancreas. Immunohistochemical examination revealed that the neoplastic cells strongly expressed chromogranin A, synaptophysin, and CD56 proteins. The tumor cells did not express HepPar-1, glypican-3, S-100, CK7, and CK19 in the liver tumor. A distal bile duct in pancreatic tissues shows the characteristics of typical bile duct carcinoma, as an invasion of carcinoma is also seen in the pancreatic tissues. Gastrointestinal endoscopy, chest and abdominal CT, abdominal MRI, and positron emission tomography (PET)-CT were used to exclude metastatic neuroendocrine tumors of the liver. INTERVENTIONS Resection of the pancreas-duodenum, the right anterior lobe of the liver, and regional lymph nodes was performed in patients. OUTCOMES The patient had survived for 5 months after the operation. CONCLUSION A unique case of a coexistence of primary hepatic neuroendocrine carcinoma and a distal cholangiocarcinoma, which had invaded the pancreas. No treatment guidelines are established for the treatment of the unique case.

Abstract
The composite tumors of the liver are very rare, including the coexistence of HCC (hepatocellular carcinoma) with NEC (neuroendocrine carcinoma). The rare occurrence of these tumors necessitates more reported cases in order to fully understand their clinical characteristics, behaviors and treatments. Herein is described an incidental collision tumor of HCC-NEC, along with a review of the literature focusing on their clinicopathological findings and prognosis. The tumor presented here was found incidentally in the hepatectomy specimen of a 56-year-old man who had undergone liver transplantation for rapidly progressive liver failure because of alcoholic hepatitis and cirrhosis. Imaging and laboratory examinations did not demonstrate tumor-related findings. During macroscopic examination, two sharply defined and distinctive areas (1.7 cm and 0.6 cm dimension respectively) were detected among the cirrhotic nodules. The characteristic histopathological features and immunohistochemical findings allowed a diagnosis of HCC-NEC to be made. There was no evidence of recurrence and metastasis after 10 months following surgery. The present case and review revealed that these tumors are frequently found in older ages and males. Although serum markers are valuable in the discrimination of malignant tumors, their absence cannot completely rule out composite HCC-NEC. Diagnosis requires a comprehensive histopathological evaluation together with immunohistochemistry. The NEC component might influence the treatment strategy and eventually the outcome of the patient. In conclusion, the rare occurrence of HCC-NEC and the lack of diagnostic clinical signs and symptoms do not exclude their consideration in the differential diagnosis of liver tumors, especially in patients with the chronic liver disease.

Abstract
Primary combined hepatocellular carcinoma (HCC) and neuroendocrine carcinoma is a rare entity, and so is hypercalcemia due to ectopic parathyroid hormone (PTH) secretion by tumor. A 44-year old man with hepatitis B virus associated chronic liver disease presented with a hepatic mass. Hemihepatectomy discovered the mass as combined HCC and poorly differentiated cholangiocarcinoma. During adjuvant chemoradiation therapy, he presented with nausea, and multiple systemic metastases were found. Laboratory tests revealed hypercalcemia with markedly elevated PTH and neuron specific enolase. Parathyroid scan showed normal uptake in parathyroid glands, suggestive of ectopic PTH secretion. Subsequently, immunohistochemistry of neuroendocrine marker was performed on the primary lesion, and confirmed the neuroendocrine differentiation in non-HCC component. The patient died 71 days after surgery. This report may suggest the possibility of ectopic PTH secretion by neuroendocrine carcinoma of hepatic origin causing hypercalcemia. Caution for neuroendocrine differentiation should be exercised when diagnosing poorly differentiated HCC.

Abstract
Background Primary hepatic neuroendocrine carcinomas are extremely rare. Because of the rarity of PHNEC, its clinical features and treatment outcomes are not well understood. A proper diagnosis and the correct therapeutic approach therefore remain clinically challenging. Case presentation A 67-year-old man was admitted to our department because of a liver tumor. Computed tomography revealed a single liver tumor 50 mm in diameter and located in the S3 region. Biopsy and imaging findings resulted in a diagnosis of primary hepatic neuroendocrine carcinoma. Left lateral segmentectomy was performed. Immunohistochemically, the tumor cells were positive for synaptophysin, chromogranin A, and CD56. Ki-67 was positive in > 90% of the tumor cells. The final diagnosis was primary hepatic neuroendocrine carcinoma. The patient suffered two episodes of lymph node recurrence. Nonetheless, the tumor was excised to prolong survival. Thus, after lymphadenectomy, he received adjuvant chemotherapy for 6 months. Two years after surgery, the patient remains alive and in good general condition. Conclusions In most cases, primary hepatic neuroendocrine carcinoma, while extremely rare, has a poor prognosis. At present, surgical resection is a priority for curative treatment, but in patients with recurrence, combined therapies are recommended.

Abstract
RATIONALE Hepatocellular carcinoma (HCC) is known to grow in a mosaic pattern, and it can sometimes be combined with non-hepatocellular cells. Despites the variety of combination, HCC with a significant neuroendocrine carcinoma (NEC) component remains very rare. Most of the reported cases were treated as conventional HCC with a relatively poor prognosis. Early diagnosis may lead to a better treatment modality. Here, we report a case of composite HCC and small cell carcinoma (SCC) with nodal metastasis of the SCC component alone. PATIENT CONCERNS A 65-year-old man with chronic viral hepatitis C presented with abdominal discomfort for 2 months. Computed tomography and angiography of the liver showed a 4.3 cm hypervascular tumor in segment 4 and enlargement of the perihilar and paracaval lymph nodes. INTERVENTIONS Extended left lobectomy and regional lymph node dissection were performed. DIAGNOSIS The hepatic tumor was heterogeneous with two distinct gross components. The green part showed a grade III hepatocellular carcinoma with an immunoreaction to Hep Par 1, glypican 3 and α-fetoprotein, whereas the white part exhibited a small cell carcinoma, as evidenced by expressions of chromogranin A and synaptophysin. The lymph node was metastasized by the SCC component. The SCC part was also positive for vimentin with perivascular accentuation. ß-catenin immunostain showed reduced membranous expression in the SCC component, as compared to HCC. OUTCOMES The patient expired 39 days after the surgical intervention. LESSONS Clinicians should be highly alert to a composite hepatic tumor, especially in dealing with a small heterogeneous tumor (< 5 cm) with early lymph node metastasis.

Abstract
Combined primary hepatic neuroendocrine carcinoma (PHNEC) and hepatocellular carcinoma (HCC) is a very rare malignant hepatic tumor. Its prognosis and histological features are uncertain. Here we report the case of such a tumor in a 70-year-old male Japanese patient with adverse prognosis. The patient underwent a right hepatic lobectomy for a tumor mass that measured 11×10cm in diameter located in the right lobe of the liver, treated with transcatheter arterial chemoembolization (TACE) and percutaneous transhepatic portal vein embolization (PTPE) therapy five weeks before the operation. Histologically, the hepatic tumor was composed of predominantly HCC and admixed with a small part of neuroendocrine carcinoma (NEC). The NEC component was distributed as a collision-type tumor separated by fibrous bands from HCC and the combined-type tumor, focally intermingling with HCC. One month after the surgery, metastasis to abdominal lymph nodes and the lumbar vertebra was detected. Although the additional treatments of systematic chemotherapy and radiation therapy were performed, the patient died 3 months after the initial surgery.

Abstract
BACKGROUND/AIMS We investigated the clinicopathological features of hepatic neuroendocrine tumours (NET) and neuroendocrine carcinoma (NEC), which remain largely unknown. MATERIAL AND METHODS We examined 1235 tumours from 1048 patients who had undergone curative hepatectomy for liver neoplasms at Kurume University Hospital. Pathological diagnoses were based on the 2010 WHO Classification of Tumours of the Digestive System. We performed immunostaining for hepatocyte markers (eg, hepatocyte paraffin (HepPar)-1), neuroendocrine markers (eg, chromogranin A (CGA)) and the proliferation marker (Ki-67). RESULTS There were four cases of NET G2 (0.38%) and five of hepatic malignant tumours with an NEC component (HNEC) (0.48%). HNEC cases were classified into three types, that is, transitional, intermediate and separate types, according to their histological and immunohistochemical features. In the former two types, the NEC component intermingled with the moderately to poorly differentiated hepatocellular carcinoma (HCC) component or intermediate component consisting of tumour cells showing the colocalisation of CGA and HepPar-1. In the separate type, the NEC and poorly differentiated HCC components were present separately, whereas the sarcomatous HCC component was detected in the vicinity of the NEC component. Ki-67 labelling indices of the NET G2, HCC and NEC components of HNEC were 6.8%, 14.9% and 58.9%, respectively. CONCLUSIONS Primary hepatic NET and NEC are very rare tumours. The NEC component in HNEC showed high proliferative activity and influenced patient prognoses.

Abstract
Primary hepatic neuroendocrine carcinoma (NEC) with concurrent occurrence of hepatocellular carcinoma (HCC) of the liver is very rare. Only 8 cases have been reported in the literature. Concurrent occurrence of HCC and NEC in the liver is classified as combined type or collision type by histological distributional patterns; only 2 cases have been reported. Herein, we report a case of collision type concurrent occurrence of HCC and NEC, in which primary hepatic NEC was in only a small portion of the nodule, which is different from the 2 previously reported cases. A 72-year-old male with chronic hepatitis C was admitted to our hospital for a hepatic mass detected by liver computed tomography (CT) at another clinic. Because the nodule was in hepatic segment 3 and had proper radiologic findings for diagnosis of HCC, including enhancement in the arterial phase and wash-out in the portal and delay phases, the patient was treated with laparoscopic left lateral sectionectomy. The pathology demonstrated that the nodule was 2.5 cm and was moderately differentiated HCC. However, a 3 mm-sized focal neuroendocrine carcinoma was also detected on the capsule of the nodule. The tumor was concluded to be a collision type with HCC and primary hepatic NEC. After the surgery, for follow-up, the patient underwent a liver CT every 3 mo. Five multiple nodules were found in the right hepatic lobe on the follow-up liver CT 6 mo post-operatively. As the features of the nodules in the liver CT and MRI were different from that of HCC, a liver biopsy was performed. Intrahepatic recurrent NEC was proven after the liver biopsy, which showed the same pathologic features with the specimen obtained 6 mo ago. Palliative chemotherapy with a combination of etoposide and cisplatin has been administered for 4 months, showing partial response.

Abstract
Primary hepatic neuroendocrine carcinoma (NEC) is rare, and its origin, clinical features, diagnosis and treatment have not been clarified. Primary mixed NEC and hepatocellular carcinoma (HCC) is even rarer and is divided into either combined type or collision type. We report a patient with the combined type of mixed NEC and HCC. A 72-year-old male was diagnosed with HCC and underwent hepatectomy because of the presence of two tumors in his liver. Histological examination demonstrated that one of the tumors had both NEC and HCC components. The transitional zone was noted in the immunohistological examination, and the tumor was determined to be the combined type of primary mixed NEC and HCC. This was the first description of an HCC component being found in an NEC-dominant area in a primary mixed NEC and HCC tumor. Three weeks after hepatectomy, an abdominal computed tomography scan showed extensive regional and para-aortic lymphadenopathy, and early relapse was suspected in the patient. The patient died 3 months after the operation despite treatment with combination chemotherapy. This report describes an unfavorable case and summarizes all the primary mixed NEC and HCC tumor cases that have been previously reported.
