Case records of 78 patients of acute lymphoblastic leukemia have been reviewed. Complete remission occurred in seven cases following an episode of septicemia and supportive care.
Four patients with Hodgkin's disease developed thrombocytopaenic purpura during remission phase. The interval at which it occurred following chemotherapy ranged from a period of 4 months to 4 years. Detailed investigations failed to reveal recurrence of Hodgkin's disease. All patients responded well to steroid therapy. In the median duration of one year follow-up Hodgkin's disease remained under control. Thus, the occurrence of thombocytopaenic purpura in patients treated for Hodgkin's lymphoma need not imply recurrence or active Hodgkin's disease.
We observed 50 patients receiving high-dose cisplatin-based chemotherapy in a prospective, randomized double-blind trial. One group received metoclopramide (MCP) alone (total dose, 6 mg/kg), whereas the other group was given dexamethasone (DMS) (total dose, 60 mg) in addition to MCP. The patient characteristics of the two groups were comparable, confirming satisfactory randomization. Multivariate regression analysis failed to show any statistical significance in the antiemetic response between the two treatment groups. However, female patients receiving Adriamycin (Adria Laboratories, Columbus, OH) concurrently and obese persons exhibited more vomiting. The overall antiemetic response rate was 66%. Because the side effects were minimal, a higher dose of MCP is expected to improve emetic control without increasing toxicity. The use of a 36-hour assessment period in our study gave more meaningful data. An exponential increase in the dose of MCP is probably required, with respect to weight, to obtain the same antiemetic efficacy.
We report transfusion reactions due to acquired anti-IgA antibodies in a 32-year-old woman with acute lymphoblastic leukemia. Previously, such reactions have been reported only after several hundred transfusions. In our patient they commenced within the first few transfusions.
Fifteen cases of histologically proven Askin Rosai tumor were treated at Tata Memorial Hospital over a period of 3 years. Patients included 12 men and three women. Clinical features included chest wall mass (14), pain (11), bony involvement (6), fever (4), dyspnoea (4), weight loss (1), cough (1), and hemoptysis (1). Previously treated patients received different treatment protocols, which made evaluation difficult. Of our ten patients who have completed induction therapy, five received vincristine and cyclophosphamide, whereas the other five received more aggressive chemotherapy. Complete remission has been achieved in two and four of these patients, respectively. One patient in each group had recurrence of the disease, in both cases at the local site. Thus, from our preliminary data, we suggest that Askin Rosai tumor should be treated with complete surgical excision followed by an aggressive combination of chemotherapy and local radiotherapy.
We report a patient with Poland's syndrome who developed acute lymphoblastic leukemia (ALL) at 28 years of age. This is the first time that such an association has been reported from outside the United States or in an adult. The relevant literature is reviewed.
The records of 458 patients with acute lymphoblastic leukemia (ALL) have been reviewed. The diagnosis of ALL was based on clinical examination and morphological, cytochemical and immunophenotypic characteristics (20% or more blasts reacting with lymphoid monoclonal antibodies) of blood and/or bone marrow. Blast cells of 6 (1.3%) patients showed positive reaction with Sudan black B (SBB) in the absence of reactivity to any other myeloid markers. Positive reaction with SBB stain cannot be considered specific for myeloid series.
