Between 1950 and 1965, 365 patients were treated for transitional cancer of the bladder at our hospitals. A retrospective study was done, using clinical records and a histopathologic review to determine the long-term natural history of this population when treated conservatively. The natural history of 3 separate patient populations was discovered, based solely on the grading of the transurethrally resected fragments. Based on the grade on initial presentation these patients were divided into grades I, II and III. Of the patients 5 per cent in grade I, 16 per cent in grade II, 28 to 35 per cent in grade III not involving muscle and 83 per cent in grade III involving muscle died of bladder cancer. Ninety-seven patients (26 per cent) died of bladder cancer, 110 (31 per cent) died of other causes and 158 (43 per cent) have been alive more than 5 years (104 more than 10 years). Grade I tumors that progressed to a higher grade did so within 2 years of the initial diagnosis. Of the bladder cancer deaths 83 per cent occurred within 2 years of the initial diagnosis. Of 64 patients dying more than 5 years after presentation only 7 died of bladder cancer.

Inadequate left internal mammary artery (LIMA) graft to the left anterior descending artery (LAD) was encountered in 10 of 3,076 patients between 1984 and July 1990. The mean number of bypass grafts was 2.9 per patient. All patients with inadequate LIMA grafts were stable preoperatively with normal to moderately reduced left ventricular function. No technical difficulties were encountered during surgery. All patients were weaned off cardiopulmonary bypass with minimal or no inotropic support. Each patient developed myocardial ischemia of the LAD territory and/or circulatory collapse or recurrent ventricular dysrhythmia during the first 24 h postoperatively. Six patients, who were immediately re-operated on and had an additional saphenous graft to the LAD, recovered with no infarction and good functional results. Four patients, who were medically treated, developed myocardial infarction. In cases of refractory circulatory collapse and/or ventricular dysrhythmia, inadequate LIMA flow should be suspected. We recommend urgent re-operation with additional saphenous vein graft to the LAD.

Extranodal marginal zone lymphoma (EMZL) is a B-cell lymphoma arising from mucosa-associated lymphoid tissue (MALT). The disease characteristics, clinical course and treatment vary considerably based on site of involvement. Because long-term outcome data for EMZL are limited, we sought to describe the clinical details of a large number of patients with EMZL evaluated at the Case Comprehensive Cancer Center over a 12-year period to identify prognostic markers including the impact of site of involvement. We identified 211 cases of EMZL involving the stomach (30%), ocular adnexa (19%), lungs (16%) and intestines (9%). Initial treatment included antibiotics (18%), radiation (21%), rituximab (20%), chemotherapy (3%), rituximab + chemotherapy (7%), surgery (17%) or observation (8%). After a median follow-up of 44·3 months (range 2·2-214·9), median progression-free survival (PFS) was 68·2 months (95% confidence interval [CI] 54·5-111·3) and median overall survival (OS) has not been reached. Age >60 years, elevated lactate dehydrogenase level (LDH), ≥4 lymph node groups involvement, and high follicular lymphoma international prognostic index (FLIPI) were associated with inferior PFS/OS. In summary, patients with EMZL have excellent prognosis with median OS in excess of 10 years. Age, elevated LDH, advanced disease, and high FLIPI score are associated with worse outcomes.
