The solitary pulmonary nodule will be found increasingly by the use of newer imaging techniques, including computed tomography (CT) screening. The aim must be to have an approach that avoids unnecessary surgery or biopsy with their attendant risks. Plain films characterisation, CT assessment, including densitometry and enhancement, and growth patterns are(More)
Twenty patients with osteosarcoma and pathologic fractures were treated with a chemotherapeutic regimen consisting of cis-diamminedichloroplatinum-II (CDP), Adriamycin (ADR) (doxorubicin) and high-dose methotrexate with citrovorum factor "rescue" (MTX-CF). Before the introduction of the regimen, the primary tumor in two patients was treated by immediate(More)
Ninety-eight pediatric patients were treated with three separate protocols (Treatment and investigation of Osteosarcoma [TIOS] I, II, and III) and 47 developed recurrent disease (metastases and/or local recurrence). Actuarial overall disease-free survival (hereafter designated survival) was 43%. Over 90% of the patients were treated initially with(More)
Preoperative chemotherapy with intraarterial cis-diamminedichloroplatin-II (CDP) and mannitol diuresis was administered to the primary tumor in 42 patients with osteosarcoma. The dose was 150 mg/m2 and more than 90% of the infusions were administered during a 2-week period. On occasion this period was extended to 3 weeks because of temporary renal(More)
A randomized two-arm study was undertaken to determine relative tumoricidal effects of intra-arterial cis-diamminedichloroplatinum II (I/A-CDP) and high-dose methotrexate with citrovorum factor rescue (MTX-CF) in the treatment of the primary tumor in patients with osteosarcoma. Responses were evaluated by clinical, radiographic, angiographic, and pathologic(More)
Temporary neurologic abnormalities were detected in 9 of 60 patients undergoing treatment with high-dose methotrexate and citrovorum factor rescue (MTX-CF) for osteosarcoma. The incidence of abnormalities and abnormalities themselves were more severe than previously reported. This was attributed to an increased dose and more frequent administration of(More)
Acute nonlymphocytic leukemia (ANLL) developed in 2 of 142 pediatric patients with osteosarcoma treated with a cis-diamminedichloroplatinum-II (CDP)-based regimen: acute monomyelogenous leukemia (M4) with a normal female karyotype in one and acute myelogenous leukemia (M2) with t (8,21) in the other. The ANLLs occurred, respectively, in each patient 3 and 4(More)
BACKGROUND This study was designed to measure inter-observer variation between thoracic radiologists in the diagnosis of diffuse parenchymal lung disease (DPLD) using high resolution computed tomography (HRCT) and to identify areas of difficulty where expertise, in the form of national panels, would be of particular value. METHODS HRCT images of 131(More)
Sixty patients with extremity osteosarcoma were treated with intraarterial cisplatin. This was followed by surgical resection (amputation or limb salvage) and postoperative adjuvant chemotherapy utilizing two different protocols. Seventy-five percent of patients achieved an initial response. Overall disease-free survival was 58%. The number of patients(More)
Localized fibrous tumours of the pleura are rare primary pleural tumours that may exhibit malignant behaviour in approximately 20% of cases. The clinical, radiological and pathological features of five patients with malignant localized fibrous tumours of the pleura are presented. Clinical symptoms included chest pain, breathlessness and cough. Hypertrophic(More)
