Abstract: The study was designed to investigate the changes in axonal transport that result from disturbances in protein synthesis. Doxorubicin, an antineoplastic drug which interferes with the function of DNA, has a selective effect on peripheral sensory nerves because of the high vascular permeability in the dorsal root ganglia. After the intravenous administration of a moderate dose (4 mg/kg) to male Wistar rats, the transport of slow component a (SCa) was found to be retarded, transport velocity being decreased by 17% (0.85 +/- 0.06 mm/day vs 1.03 +/- 0.06 mm/day in controls). The transport kinetics of the fast anterograde and retrograde components (aFC and rFC) were unchanged after the administration of a dose of 6 mg/kg, although the relative amount of aFC was decreased by 27% (3.2 +/- 0.9% vs 4.4 +/- 1.1% in controls). It is suggested that the neuronopathy induced by doxorubicin is mediated by changes in axonal transport.

Abstract: Many patients with diffuse malignant pleural mesothelioma have dyspnea or chest pain. Cardiac symptomatology is frequently difficult to differentiate from symptoms of pleuropulmonary disease. To better define the clinical characteristics of cardiac involvement in patients with mesothelioma, the electrocardiographic (EKG) and echocardiographic findings in 64 patients with biopsy-proven malignant pleural mesothelioma were reviewed. A total of 19/64 (30%) patients had autopsy studies available for review. The EKG was abnormal in 55 patients (89%). Over half (60%) had an arrhythmia, including sinus tachycardia (42%), premature atrial and ventricular contractions (13%), atrial fibrillation (3%), and atrial flutter (1%). Over one third (37%) had a conduction abnormality, including bundle branch block (13%), hemiblock (8.5%), and incomplete right bundle branch block (13%). Echocardiography revealed a total of 13 patients with pericardial effusions, two with pericardial thickening, and one with an anterior sonolucent space. Of 19 autopsies, cardiac invasion was found in 14 (74%), with more than half to the pericardium and more than one quarter to the myocardium. It is concluded that: clinical cardiac abnormalities occur in the great majority of patients with malignant pleural mesothelioma, pathologic cardiac invasion occurs in the great majority of patients with pleural mesothelioma, and the EKG and echocardiogram are helpful in differentiating cardiac involvement from progressive pulmonary disease in patients with pleural mesothelioma.

Abstract: The gall bladder mucosa is composed of neutral mucopolysaccharide and protein radical containing secretory cells, protein radical containing migratory cells, and neutral and acid mucopolysaccharides plus sialic acid containing goblet cells. The prognostic significance of histologic or histochemical parameters in gall bladder adenocarcinoma (GBA) are unknown. To determine if histochemical acid mucopolysaccharide content in GBA has prognostic value, GBA histologic sections from 26 advanced stage disease patients participating in Eastern Cooperative Oncology Group (ECOG) treatment study EST-2273 were stained with alcian blue at pH. 1.0, assessed by a pathology panel for either high (greater than 50%) or low (less than 50%) acid mucopolysaccharide content, and correlated with patient survival. Initial panel unanimous concurrence rate on acid mucopolysaccharide content was 88.9%. Median survival times from the start of chemotherapy to date of death for high acid mucopolysaccharide content GBA was 14 weeks versus five weeks for the low content GBA (P less than 0.0001). The results indicate that high acid mucopolysaccharide content in GBA significantly improves prognosis. ECOG recommends stratification by acid mucopolysaccharide content in future GBA treatment investigations.
