Abstract
RATIONALE Pulmonary embolism (PE) has diverse clinical manifestations and syncope might be the first or only symptom of PE. Tumor disease usually presents with symptoms associated with the primary site, however, PE may be the first manifestation of occult tumors. PATIENT CONCERNS Here, we report 2 patients admitted to our hospital because of syncope. One patient had a chronic hepatitis B history of more than 20 years and the other patient had chronic heavy drinking for many years. Neither patient had been diagnosed with neoplastic disease before admission. DIAGNOSES Clinical examinations, including laboratory tests and imaging tests upon admission demonstrated PE resulting in syncope. Furthermore, malignant hepatocellular carcinoma (HCC), inferior vena cava, and right atrium tumor thrombus were diagnosed. INTERVENTIONS Thrombolysis and anti-coagulation therapy were performed immediately after the diagnosis of PE. Twenty-seven HCC patients with PE in 27 articles from 1962 to 2020 in the PubMed database were reviewed. OUTCOMES The improvement was achieved that no syncope recurred after treatment of PE. The oxygen partial pressure increased and the D-dimer level decreased. The clinical characteristics of 27 HCC patients with PE were summarized and analyzed. LESSONS It is important for clinicians to be aware that occult carcinoma might be a reason for patients with PE presenting with syncope. If PE cannot be explained by common causes, such as our patient, and HCC should be highly suspected when inferior vena cava and right atrial mass are found on imaging tests.

Abstract
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer and cancer related deaths worldwide. Metastasis of HCC into the cardiac cavity is mostly caused by direct tumor thrombus invasion through the major hepatic veins and of vena cava inferior with continuous extension into the right cardiac cavity. Right heart metastasis without invasion of inferior vena cava (IVC), which may be caused by haematogenous spread of cancer cells, is rarely reported. We report a case of HCC with IVC and right atrium (RA) thrombus in a patient who presented to us with decompensated cardiac failure. Strikingly, the patient was young and with negative serum HBsAg, and anti-HCV results. Our case highlights a rare presentation of metastatic intracardiac tumor thrombus involving the RA in advanced HCC without any symptoms of cardiac failure, and henceforth, the role of screening echocardiography for all patients with advanced HCC especially with vena caval involvement to rule out intracardiac thrombus.

Abstract
Background Pulmonary tumor embolism (PTE) is difficult to detect before death, and it is unclear whether the discrepancy between antemortem clinical and postmortem diagnosis improves with the advance of the diagnostic technologies. In this study we determined the incidence of PTE and analyzed the discrepancy between antemortem clinical and postmortem diagnosis. Methods We performed a retrospective autopsy study on patients with the history of malignant solid tumors from 1990 to 2020 and reviewed all the slides of the patients with PTE. We also analyzed the discrepancies between antemortem clinical and postmortem diagnosis in 1999, 2009 and 2019 by using the Goldman criteria. Goldman category major 1 refers to cases in which an autopsy diagnosis was the direct cause of death and was not recognized clinically, but if it had been recognized, it may have changed treatment or prolonged survival. Results We found 20 (3%) cases with PTE out of the 658 autopsy cases with solid malignancies. Out of these 20 cases, urothelial carcinoma (30%, 6/20) and invasive ductal carcinoma of the breast (4/20, 20%) were the most common primary malignancies. Seven patients with shortness of breath died within 3–17 days (average 8.4±2.2 days) after onset of the symptoms. Pulmonary embolism was clinically suspected in seven out of twenty (35%, 7/20) patients before death, but only two patients (10, 2/20) were diagnosed by imaging studies before death. The rate of Goldman category major 1 was 13.2% (10/76) in 1999, 7.3% (4/55) in 2009 and 6.9% (8/116) in 2019. Although the rate of Goldman category major 1 appeared decreasing, the difference was not statistically significant. The autopsy rate was significantly higher in 2019 (8.4%, 116/1386) than in 2009 (4.4%, 55/1240). Conclusions The incidence of PTE is uncommon. Despite the advances of the radiological techniques, radiological imaging studies did not detect the majority of PTEs. The discrepancy between the antemortem clinical and the postmortem diagnosis has not improved significantly over the past 30 years, emphasizing the value of autopsy.

Abstract
In recent years, emerging immunotherapy has been included in various malignant tumor treatment standards. Temperature has been considered to affect different pathophysiological reactions such as inflammation and cancer for a long time. However, in tumor immunology research, temperature is still rarely considered a significant variable. In this review, we discuss the effects of room temperature, body temperature, and the local tumor temperature on the tumor immune microenvironment from multiple levels and perspectives, and we discuss changes in the body's local and whole-body temperature under tumor conditions. We analyze the current use of ablation treatment-the reason for the opposite immune effect. We should pay more attention to the therapeutic potential of temperature and create a better antitumor microenvironment that can be combined with immunotherapy.

Abstract
Acute distress immediately following an 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) scan is an exceedingly rare event. We report a case whose condition was suddenly deteriorated in the nuclear medicine laboratory, and whose diagnosis was confirmed by FDG-PET/CT. A 67-year-old woman with left renal cell carcinoma (RCC) suddenly complained of dyspnea and tachycardia just after undergoing FDG-PET/CT. PET/CT images showed increased FDG uptakes in the left renal vein, inferior vena cava, right atrium, and bilateral hila. She was diagnosed with a massive tumor embolism from the inferior vena cava to both pulmonary arteries, and urgently underwent tumor embolectomy. FDG-PET/CT was helpful for diagnosing the tumor embolism and differentiating it from bland thromboembolism in this patient with RCC.

Pulmonary tumor thrombotic microangiopathy of hepatocellular carcinoma: A case report and review of literature. World J Gastroenterol 2019; 25:6949-6958. [PMID: 31908398 PMCID: PMC6938728 DOI: 10.3748/wjg.v25.i48.6949] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Revised: 12/06/2019] [Accepted: 12/22/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare condition in patients with hepatocellular carcinoma (HCC); to date, few cases have been reported. While hepatic dysfunction has been focused on the later stages of HCC, the management of symptoms in PTTM is important for supportive care of the cases. For the better understanding of PTTM in HCC, the information of our recent case and reported cases have been summarized.
CASE SUMMARY A patient with HCC exhibited acute and severe respiratory failure. Radiography and computed tomography of the chest revealed the multiple metastatic tumors and a frosted glass–like shadow with no evidence of infectious pneumonia. We diagnosed his condition as acute respiratory distress syndrome caused by the lung metastases and involvement of the pulmonary vessels by tumor thrombus. Administration of prednisolone to alleviate the diffuse alveolar damages including edematous changes of alveolar wall caused by the tumor cell infiltration and ischemia showed mild improvement in his symptoms and imaging findings. An autopsy showed the typical pattern of PTTM in the lung with multiple metastases.
CONCLUSION PTTM is caused by tumor thrombi in the arteries and thickening of the pulmonary arterial endothelium leading to the symptoms of dyspnea in terminal staged patients. Therefore, supportive management of symptoms is necessary in the cases with PTTM and hence we believe that the information presented here is of great significance for the diagnosis and management of symptoms of PTTM with HCC.

Abstract
Adenocarcinoma of the prostate is occasionally associated with pulmonary embolism, occurring as a result of secondary hypercoagulable states or cancer-associated emboli. The objective of this study was to provide a review of clinical, histopathological and immunohistochemical features of poorly differentiated prostatic adenocarcinoma, emphasizing the relevance of undiagnosed malignancy as a cause of pulmonary embolism. The current study describes the case of a 78-year-old male who experienced remarkable clinical symptoms suggestive of pulmonary embolism. Following several diagnostic examinations, the patient was diagnosed with pulmonary embolism, which led to the detection of prostatic adenocarcinoma. Poorly differentiated adenocarcinoma with a Gleason's score of nine was set as a definite diagnosis. Multiple tumor emboli within small and medium-sized pulmonary blood vessels were found in all specimens taken from lung tissue. Immunohistochemical analysis showed diffuse and strong positivity of tumor cells within pulmonary arteries. Hidden malignancy is a diagnostic challenge that should be considered in the differential diagnosis of pulmonary embolism. Laboratory and radiological findings with additional histopathological evaluation are needed for the definite diagnosis.

Abstract
OBJECTIVE Arterial neoplastic emboli are uncommon, accounting for <1% of thromboemboli in the current literature. Nonetheless, this event may be associated with significant morbidity and mortality. Herein, we report a series of 11 cases of arterial neoplastic emboli from a single tertiary care center along with a comprehensive review of the literature to date. The aim of this study was to document the incidence, clinical presentations, and complications of arterial neoplastic emboli as well as to highlight the importance of routine histologic examination of thrombectomy specimens. METHODS Pathology archives from a single tertiary care institution were queried to identify cases of surgically resected arterial emboli containing neoplasm (1998-2014). Histopathology was reviewed for confirmation of diagnosis. Patient demographics and oncologic history were abstracted from the medical record. Comprehensive literature review documented 332 patients in 275 reports (1930-2016). RESULTS Eleven patients (six men) with a median age of 63 years (interquartile range, 42-71 years) were identified through institutional archives. Embolism was the primary form of diagnosis in seven (64%) cases. Cardiac involvement (primary or metastasis) was present in more than half of the cohort. Comprehensive literature review revealed that pulmonary primaries were the most common anatomic origin of arterial neoplastic emboli, followed by gastrointestinal neoplasia. Cardiac involvement was present in 18% of patients, and sentinel identification of neoplasia occurred in 30% of cases. Postmortem evaluation was the primary means of diagnosis in 27%. CONCLUSIONS This study highlights the importance of routine histopathologic evaluation of embolectomy specimens in patients with and without documented neoplasia.

Abstract
Sorafenib (Nexabar, Bayer, Berlin, Germany), one of multikinase inhibitors, can infrequently downstage advanced hepatocellular carcinoma (HCC). There are some reports that sorafenib in combination with other modalities, such as transcatheter arterial chemoembolization (TACE) or radiation therapy, could represent a bridge to surgery. We have observed a progressive HCC case with hepatic vein tumor thrombosis proceeding to the inferior vena cava (IVC-HVTT) convert to a state of feasible curative resection after a multidisciplinary treatment which included sorafenib. The patient underwent a successful resection in consequence of this therapy. A 45-year-old male with Hepatitis B Virus-associated chronic hepatitis was diagnosed as HCC with IVC-HVTT. To obtain oncological curative resection, we performed TACE, radiation therapy followed by administration of sorafenib (800 mg per day, total 72 g). The tumor including IVC-HVTT remarkably shrank, therefore, an extended posterior sectionectomy and total removal of the IVC-HVTT was successfully performed. The operation time was 736 minutes and the amount of intraoperative hemorrhage was 805 mL. No postoperative complication occurred. Adjuvant therapy with sorafenib was started four weeks after the operation and continued for 6 months (800 mg per day, total 144 g). The patient is alive without recurrence for about 4 years from the initial therapy. Multidisciplinary therapy including sorafenib, TACE, radiation, and hepatic resection may be an effective strategy to treat HCC patients with IVC-HVTT.

Abstract
Adhesion to the extracellular matrix and endothelial lining of blood vessels is critical for tumor cells to grow at original or metastatic sites. Inhibition of tumor cell adhesion can be an antitumor strategy. Guanosine-rich (G-rich) oligodeoxynucleotides (ODNs) can inhibit the adhesion of certain tumor cells. However, no data exist on how inclusion of the CpG motif in the G-rich sequence influences tumor cell adhesion and subsequent tumorigenesis. In this study, in vitro and in vivo assays were used to evaluate how a panel of ODN-containing contiguous guanosines and the CpG motif influenced adhesion of B16 melanoma cells. The results showed that a self-designed ODN, named BW001, containing the polyG motif and a full phosphorothioate modification backbone could inhibit B16 melanoma cell adhesion on a culture plate or on a plate coated with various substances. In vivo data revealed that B16 melanoma cells co-administered with BW001 and intraperitoneally injected into mice formed fewer tumor colonies in peritoneal cavities. This effect was related to the polyG motif and the full phosphorothioate modification backbone and enhanced by the existence of the CpG motif. Additional in vivo data showed that survival of tumor-bearing mice in the BW001 group was significantly prolonged, subcutaneous melanoma developed much more slowly, and lung dissemination colonies formed much less often than in mice inoculated with B16 melanoma cells only. The effect was CpG motif-dependent. These results suggest that BW001 may exert an integrated antitumor effect.

Abstract
Hepatocellular carcinoma usually metastasizes to regional lymph nodes, lung, and bones but can rarely invade the inferior vena cava with intravascular extension to the right atrium. We present the case of a 75-year-old man who was admitted for generalized oedema and was found to have advanced HCC with invasion of the inferior vena cava and endovascular extension to the right atrium. In contrast to the great majority of hepatocellular carcinoma, which usually develops on the basis of liver cirrhosis due to identifiable risk factors, none of those factors were present in our patient.

Abstract
Spontaneous regression of hepatocellular carcinoma (HCC) is an extremely rare phenomenon. We herein report the case of a 73-year-old man who showed the spontaneous regression of multiple pulmonary recurrences of HCC that had occurred after hepatectomy. The patient was undergoing dialysis due to diabetic renal failure when ultrasonography revealed a liver tumor (diameter ~ 10 cm). A preoperative diagnosis of HCC with hepatic vein thrombosis was made. The liver function was well preserved and then the right hepatic vein area was resected. Two months after hepatectomy the α-fetoprotein level increased, and multiple lung nodules were observed on follow-up computed tomography. A diagnosis of multiple lung metastases was made, but no therapy was started because of the patient's renal failure. Five months after hepatectomy the α-fetoprotein level normalized, and the metastases regressed completely. The patient is now doing well without any recurrence at 13 months after the surgery. The associated literature on spontaneous HCC regression is also reviewed.

Abstract
During hospitalization for evaluation of a large testicular tumor with extensive metastatic disease, this 14-year-old boy collapsed while showering and could not be resuscitated. At autopsy, there was no evidence of thromboembolic phenomenon, a known cause of sudden death in metastatic testicular tumors and other large abdominal tumors. However, marked compression of the inferior vena cava by a large pelvicoabdominal tumor mass and findings suggestive of systemic-portal shunting were consistent with the death due to the impaired venous return via the inferior vena cava.

Complete remission of multiple recurrent hepatocellular carcinomas by oral administration of enteric-coated tegafur/uracil in a patient with huge hepatocellular carcinoma extending to the inferior vena cava after hepatic resection: analysis of mRNA expression of fluoropyrimidine metabolism enzymes in the primary tumor.

Abstract
We herein report the complete remission of multiple recurrent hepatocellular carcinomas (HCCs) by the oral administration of tegafur/uracil (UFT) alone. A 56-year-old Japanese man with two huge HCCs was admitted and underwent hepatic resection. Intraoperative ultrasonography revealed that the tumor thrombus extended to the inferior vena cava (IVC) with a small tumor in the left hepatic lobe. Right trisectionectomy of the liver, removal of the tumor thrombus in the IVC, and partial resection of the left lobe were performed. Microscopic examination revealed that the larger tumor was moderately to poorly differentiated HCC and the smaller tumor was well-differentiated HCC. The small tumor in the left lobe was diagnosed as an intrahepatic metastasis of the larger tumor. Two months after the surgery, computed tomography (CT) revealed multiple HCC recurrences in the remnant liver, but complete remission was achieved by the administration of UFT alone. To clarify the reason for the good response of the recurrent HCC to UFT, the mRNA expression level of several fluoropyrimidine metabolism enzymes was measured in resected specimens. A lower expression of thymidine phosphorylase (TP) might explain the good response to UFT. The patient is alive without intra- or extrahepatic recurrence more than 6 years after the hepatic resection.

Abstract
Sudden and unexpected natural deaths and nonnatural deaths may result from various pulmonary conditions. Additionally, several nonpulmonary conditions of forensic significance may be complicated by the development of respiratory lesions. Certain situations with pulmonary pathology are particularly likely to be critically scrutinized and may form the basis of allegations of medical negligence, other personal injury liability, or wrongful death.1

Predictors of hepatic venous trunk invasion and prognostic factors in patients with hepatocellular carcinomas that had come into contact with the trunk of major hepatic veins.

Abstract
PURPOSE In this study, we tried to identify the preoperative predictors of hepatic venous trunk invasion and the prognostic factors in patients with hepatocellular carcinoma (HCC) that had come into contact with the trunk of a major hepatic vein over a distance of 1.0 cm or more. METHODS Forty patients who had such HCCs resected were entered into this study and predictors of hepatic venous trunk invasion and prognostic factors were evaluated by univariate and multivariate analyses. RESULTS AND CONCLUSIONS A combined resection of the HCC and the venous trunk was performed in 29 patients. Hepatic venous trunk invasion was observed in 12 patients, including 2 with inferior vena cava tumor thrombus. A stepwise logistic regression analysis indicated that tumors larger than or equal to 7 cm in diameter and tumors showing a poorly differentiated histological grade were independent predictors of hepatic venous trunk invasion. The survival of patients without venous trunk invasion was significantly better than that for patients with venous trunk invasion (P = 0.048). A univariate analysis revealed that Child-Pugh classification B (P = 0.002), a high des-gamma-carboxy prothrombin concentration (> or =400 mAU/ml, P = 0.023), a large HCC (> or =5.0 cm in diameter, P = 0.002), the presence of portal vein invasion (P < 0.001), the presence of venous trunk invasion (P = 0.048), the presence of intrahepatic metastasis (P < 0.001), and poorly differentiated HCC (P = 0.006) correlated with a worse overall survival after hepatic resection. In a multivariate analysis, however, only the presence of intrahepatic metastasis (P = 0.037, relative risk 8.25) was an independent predictor of poor overall survival. CONCLUSIONS Large tumors (> or =7 cm in diameter) and poorly differentiated HCCs were more likely to be associated with hepatic venous trunk invasion and intrahepatic metastasis was an independent prognostic factor in patients with HCC that had come into contact with the trunk of a major hepatic vein.

Abstract
BACKGROUND The specific incidence of thrombotic pulmonary embolism (PE), tumor PE and tumor invasion into large veins according to tumor type and tumor site remains unclear. METHODS AND RESULTS A total of 65,181 cancer patients were identified from 98,736 postmortem examinations. Thrombotic PE occurred in 2.32% of all cancer patients and comprised 88.6% of the total number of all PE events. The incidence of thrombotic PE was high in those with adenocarcinoma, leukemia and large cell carcinoma, and was low in those with hepatic cell carcinoma. The incidence of PE was high when tumor was present in hematogenous tissue, lungs, ovaries, pancreas and the biliary system, and was low when tumor was present in the liver. The incidence of tumor PE was high with large cell carcinoma, hepatic cell carcinoma and adenocarcinoma, and was also high when tumor was present in the lungs, ovaries, kidneys and liver. There was a significant correlation between the incidence of tumor PE and the incidence of tumor invasion into large veins. CONCLUSION The incidence of thrombotic PE, tumor PE and tumor invasion into large veins varies significantly according to tumor histopathology and tumor site.

Abstract
A 48-year-old patient with known alcohol abuse and long-standing liver cirrhosis presented with spontaneous bacterial peritonitis and subsequent hepato-renal syndrome. Autopsy revealed a large hepatocellular carcinoma of the right liver lobe. Histologically, pulmonary arteries, arterioles, and capillaries were occluded by numerous tumor emboli. Small tumor emboli also covered the endocardium of the right ventricle. A review of the literature shows that macroscopic as well as microscopic pulmonary tumor embolism is often diagnosed in patients with a previously unknown malignancy. Moreover, pulmonary tumor embolism radiologically mimics pneumonia, tuberculosis, or interstitial lung disease. Therefore, an autopsy should be considered in cases of fulminant or massive pulmonary embolism to exclude tumor embolism even when the patients' history is insignificant as to this point, and in cases with known malignant tumors and respiratory symptoms to exclude tumor microembolism.
