Lymphocyte-predominant Hodgkin’s lymphoma (LPHL) differs in histologic and clinical presentation from classical Hodgkin’s
lymphoma (cHL). Treatment of LPHL patients using standard Hodgkin’s lymphoma protocols leads to complete remission in more
than 95% of patients. Survival and freedom from treatment failure are substantially worse in advanced-stage patients than
for early-stage patients. Thus, patients in advanced stages and those in early stages with unfavorable risk factors should
be treated similar to those with cHL. In contrast, patients with early-stage LPHL without risk factors might be sufficiently
treated with reduced-intensity programs having less severe adverse effects. As a result, treatment of early LPHL is rather
heterogeneous, including radiotherapy using extended-fleld technique, involved-fleld radiotherapy (IF-RT), combined-modality
treatment, and, more recently, monoclonal antibodies. Watch-and-wait strategy plays an important role in pediatric oncology,
to avoid adverse effects associated with therapy. IF-RT seems to be emerging as a treatment of choice for patients with stage
IA LPHL; most larger study groups, such as the German Hodgkin Study Group and the European Organisation for Research and Treatment
of Cancer, have adopted IF-RT as the treatment of choice for these patients. 相似文献

Four cases of high-flow carotid-cavernous sinus fistula (CCF), three of them posttraumatic and one spontaneous, have been treated by a direct surgical approach to the cavernous sinus. The CCF's were obliterated by the introduction into the cavernous sinus of muscle fragments and/or fibrin sealant. In the three cases with a preoperatively patent internal carotid artery (ICA), the CCF was occluded and the ICA flow preserved. One of these also had a posttraumatic false aneurysm that enclosed the two avulsed ends of a transected intracavernous ICA. This was treated by cervical ICA ligation following resolution of the CCF. A fourth patient, who had previously undergone an unsuccessful ICA trapping procedure elsewhere, also obtained a good result. The case histories and the surgical technique are presented. Direct intracavernous obliteration with muscle fragments and fibrin sealant fulfills the criteria for treatment of high-flow CCF's: occlusion of the arteriovenous fistula and preservation of the ICA circulation. While this surgical technique is a therapeutic option in some cases, it appears to have precise indications in others. 相似文献

Hypoxia is related to poor prognosis because it is associated to chemo-and radioresistance. During recent years the evolution
of imaging methods like PET/CT and MRI has meant the appearance of new perspectives with direct implications in radiation
therapy. We discuss previous experiences in staging, planning and in the follow-up process with these techniques for measuring
tumour hypoxia. 相似文献

Almost 90% of primary acute pericarditis are idiopathic. Between specifics forms, a very low percentage of cases are due to chronic rheumatic diseases. A case of adult Still's disease (juvenile chronic rheumatoid arthritis) with acute pericarditis being the first clinical manifestation (besides fever and general syndrome) is presented. Therapy with oral prednisone was rapidly effective, and pericardial effusion resolved after 3 weeks of treatment, as echocardiography showed. 相似文献

In a family 6 members in 3 generations were affected by centronuclear myopathy (CNM) of autosomal dominant inheritance. The apparent onset was in the early forties and the disease progressed slowly. Limb weakness was predominant. Strabismus was present in 5 cases and calves hypertrophy in 3. Serum creatinine kinase was always within the normal range. In one case myotonic bursts were found at electromyography. In 2 cases brain stem auditory evoked potential studies demonstrated abnormal prolongation of interpeak latencies I-III and favoured subclinical nervous system involvement. Muscular biopsies showed typical features of centronuclear myopathy with 50 to 80% central nuclei. In two cases immunocytochemical labelling of dystrophin showed staining in the sarcoplasm in favour of an arrest in the morphogenesis of developing myofiber. Others families with autosomal dominant CNM in the literature and also some sporadic adult cases had similar clinical features. 相似文献
