The clinical and pathological features of 24 patients with cerebral emboli complicating 66% of our cases of nonbacterial thrombotic endocarditis (NBTE) associated with carcinoma are reviewed. Twelve patients were admitted for a cerebrovascular accident (CVA) while 4 patients developed a CVA during hospitalization. Transient ischemic attacks preceded the CVA in 3 patients. More often the CVA took the form of a single sudden accident. Cerebral infarcts however were generally multiple and hemorrhagic and varied in size and age. In 4 patients large softenings were directly responsible for death. 8.6% of cerebral embolisms were caused by NBTE and in 10 patients cerebral embolization was the first symptom of a carcinoma. The frequency of NBTE in ovarian carcinoma even in the absence of metastases may motivate a more aggressive approach towards unexplained cerebral embolism.

The disease of a 34-year-old patient with relapsing cerebral embolisms, endocarditis, thrombophlebitis and hypercoagulopathy had the characteristics of paraneoplastic syndromes described and discussed in literature. Autopsy yielded a clinically unrecognised, dedifferentiated adenocarcinoma of the bronchial system. At an early stage of the disease cerebral embolisms had produced severe cerebral neurological signs with varying manifestations. This influenced not only the clinical picture and course of the disease to a considerable extent, but also focussed diagnostic attention on these signs to such a degree that the possibility of a masked carcinoma did not seem to suggest itself. The assumption of paraneoplastic linkups is supported by experimental and postmortem examinations on metabolic and immunological remote action of tumours on cardiac valves and on the vascular and coagulation system. However, the exact pathogenetic details are still largely unknown.

Infectious mural endocarditis is uncommon and not well documented. The clinical setting and pathologic features of five patients with Aspergillus mural endocarditis are described. Leukemia, carcinoma, renal transplantation, and hepatic failure were the primary diseases. Associated conditions include high-dose corticosteroids, cytotoxic therapy, renal failure, gram-negative sepsis, and endotracheal intubation. All patients received prolonged antibiotic therapy or treatment with three or more antibiotics. All had clinically undetected aspergillosis and severe fungal pneumonia. Fungal myocardial abscesses were present in each patient. Aspergillus mural endocarditis developed in more than 40% of patients with cardiac aspergillosis. Endocardial vegetations were contiguous with underlying myocardial infection; yet they may develop initially as a subendocardial focus rather than from a myocardial abscess. Aspergillus mural endocarditis progressed to destroy the mitral valve ring and served as a source of mycotic embolization to vital organs.

Terminal endocarditis develope in cancer patients almost latently. There is no difference between the so-called "tumor-endocarditis" and other verrucous endocarditis associated with terminal tuberculosis, sepsis or rheumatism. It is more frequent in cases with large or ulcerated primary tumours and multiple metastases than in cases with early cancer. It also develope more frequently in well differentiated cancer (squamous and adenocarcinoma) than in indifferentiated forms of cancer. Terminal endocarditis is often seen in patients with cancer of the gallbladder, pancreas, liver, stomach, rectum, and ovary. In carcinoma of the liver, pancreas and biliary tract the trend to embolism is more reduced through icterus than the trend to terminal endocarditis.

Attention has recently been drawn to the association of digestive carcinoma and streptococcus bovis endocarditis. The authors studied 130 records of patients with endocarditis and an association with a digestive tumour (3 neoplasms, one villous tumour) was found in four. Streptococcus bovis was demonstrated in one case, streptococcus faecalis in two and streptococcus durans in one. The association of carcinoma and subacute endocarditis would thus seem to not solely relate to digestive commensual organisms. The question of common factors favourising carcinoma and endocarditis is raised.

The pathological features of 12 acinar cell neoplasms of the pancreas are described; these comprise 11 carcinomas, of which seven were pure acinar cell growths and four were mixed acinar and ductal carcinomas, and one adenoma. These tumors occurred in a series of 105 during the period 162-75. Thrombotic endocarditis developed in three out the 11 carcinoma cases. The distinctive histological features of these neoplasms and the means of differentiating them from anaplastic carcinomas and certain other carcinomas, for example, islet cell carcinoma, oat cell carcinomas, and carcinoid tumours, are discussed. The poor prognosis of pancreatic cancers is emphasized, and reasons are put forward for believing that future epidemiological studies may need to take account of the histological types of pancreatic carcinoma.

A group of 175 patients had barium enema. Pour-plate blood cultures were obtained immediately before and after the procedure and 5, 10, 15, and 30 minutes later. Bacteremia was demonstrable in 20 (11.4%) patients. In some, blood cultures were positive for as long as 15 minutes after barium enema; all were negative at 30 minutes. Among the bacteria associated with the 20 episodes of bacteremia were Escherichia coli, Klebsiella, enterococci, Proteus morganii, Bacteroides, and Veillonella. The incidence of bacteremia among patients with ulcerative colitis, regional enteritis, rectal polyps, colonic or rectal carcinoma, nonspecific diarrhea, or other lower intestinal tract disorders was not much different from patients free of rectosigmoid disease. The results of this study suggest that a history of recent barium enema may be important in patients who have endocarditis.

Two subjects with cerebral embolism were found at autopsy to have marantic (nonbacterial thrombotic) endocarditis (NBTE) and an unsuspected carcinoma. A additional 16 subjects with marantic endocarditis and cancer were found on reviewing the autopsy records of 22 subjects with NBTE. Of these 18 subjects with NBTE and cancer, eight developed a stroke during their illness, in five as the initial manifestation of cancer. Although the association of cancer and marantic endocarditis is generally well recognized, cerebral embolism from this source should be more seriously considered as one of the "remote effects" of cancer on the nervous system.

About 15% of patients with cancer have cerebrovascular lesions, resulting from 4 kinds of disorders sometimes intermingled in advanced disseminated cancer: coagulation disorders, direct effects of the tumor, infections and therapeutic measures. Infarction, hardly less frequent than hemorrhage, mostly complicates lymphoma and carcinoma. Hypercoagulation states, such as chronic disseminated intravascular coagulation, nonbacterial thrombotic endocarditis, and nonmetastatic cerebral venous thrombosis account for about 50% of cases. Tumor emboli, as seen in intravascular malignant lymphomatosis, arteritis related to aspergillus, granulomatous angiitis with or without herpes zoster and radiation-induced atherosclerosis are rarer. Cerebral hemorrhages, excluding bleeding from the metastases of choriocarcinoma and melanoma are mainly associated with leukemia by acute disseminated intravascular coagulation as in promyelocytic leukemia, by leukostasis or by pancytopenia. Both infarction and hemorrhage rarely reveal the neoplasia. Lesions are often small and disseminated, and therefore produce a picture of diffuse acute or subacute encephalopathy rather than acute focal deficits. Finally, there may be no relationship between the cerebrovascular event and the neoplasia, and atherosclerosis or traumatic subdural hematoma may well be the causal factor.

The problems arising from the discovery of a colorectal tumor during an infectious endocarditis caused by Streptococci D have rarely been mentioned in the surgical literature. The frequency of association of an asymptomatic colorectal tumor and of a Streptococcus bovi endocarditis is now undisputed. This notion implies the systematic search for an intestinal lesion (adenoma or carcinoma) in case of endocarditis or septicemia without involvement of the valves, caused by a streptococcus of group D. The authors report about 3 cases of enterococcal (1 case) and S. bovis (2 cases) infectious endocarditis revealing a colic adenocarcinoma (2 cases) and a villous adenoma (1 case), all being perfectly latent. The specific therapeutic problems arising from this association are outlined, including the antibiotic therapy, the role of the anticoagulant treatment and the priority given to valve surgery in case of hemodynamic instability.
