Dose-intense chemotherapy every 2 weeks with dose-intense cyclophosphamide, doxorubicin, vincristine, and prednisone may improve survival in intermediate- and high-grade lymphoma: a phase II study of the Southwest Oncology Group (SWOG 9349).

PURPOSE: To test the hypothesis that therapy of intermediate- and high-grade (excluding Burkitt lymphoblastic) lymphoma with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) could be safely dose-intensified with routine filgrastim support. PATIENTS AND METHODS: Eligible patients were those who were previously untreated and who had either bulky stage II, or stage III or IV lymphoma with working formulation histology D, E, F, G, H, or J; performance status < or = 2; and acceptable end organ function. No upper age limit was specified. Therapy was dose-intensified CHOP (CHOP-DI) with filgrastim support. Each course was repeated every 14 days for six planned courses. RESULTS: Eighty-eight eligible patients were treated with CHOP-DI and had a median follow-up of 5.1 years on this phase II study, designated Southwest Oncology Group (SWOG) 9349. The progression-free survival was 51% at 2 years and 41% at 5 years. The overall survival was 60% at 5 years. Three fatal treatment-related events occurred. One patient with myelodysplastic syndrome was reported. CONCLUSION: Treatment with CHOP-DI can be safely administered in the cooperative group setting and results in improved survival. Estimated overall survival at 5 years was 14% better than that of patients treated with standard-dose CHOP in an earlier SWOG study, although progression-free survival of 60% at 2 years-the prespecified end point-was not achieved. CHOP-DI, given every 2 weeks at escalated doses, is a strategy that should be tested in a future randomized clinical trial in lymphoma.     

Health status and quality of life in patients with early-stage Hodgkin's disease treated on Southwest Oncology Group Study 9133.

PURPOSE: We describe the short and intermediate-term quality-of-life (QOL) outcomes in patients treated on a randomized clinical trial in early-stage Hodgkin's disease (Southwest Oncology Group [SWOG] 9133) comparing subtotal lymphoid irradiation (STLI) with combined-modality treatment (CMT). PATIENTS AND METHODS: Two hundred forty-seven patients participated in the QOL study (SWOG 9208), completing several standardized instruments (Symptom Distress Scale; Cancer Rehabilitation Evaluation System - Short Form; Medical Outcomes Study 36-Item Short-Form Health Survey Vitality Scale; and a health perception item), as well as questions about work, marital status, and concerns about having children. This article reports on results from baseline before random assignment, at 6 months, and at 1 and 2 years after random assignment. RESULTS: Patients receiving CMT experienced significantly greater symptom distress (P <.0001), fatigue (P =.001), and poorer QOL (P =.015) at 6 months than the STLI patients, reflecting a shorter time since completion of therapy in the CMT arm. Importantly, patients in the two groups did not differ on any outcomes at the 1-and 2-year assessments. Both patient groups reported significantly more fatigue before treatment than healthy reference populations, and fatigue did not improve in either group after treatment. CONCLUSION: This study demonstrated that patients with early-stage Hodgkin's disease experience a short-term decrease in QOL and an increase in symptoms and fatigue with treatment, which is more severe with CMT; by 1 year, however, CMT and STLI patients report similar outcomes. Fatigue scores for both arms were lower at baseline than scores for the general population and did not return to normal levels 2 years after random assignment. The mechanisms responsible for this lingering problem warrant further investigation.     

Smoking among participants in the childhood cancer survivors cohort: the Partnership for Health Study.

PURPOSE: This article describes baseline data collection and the intervention design of Partnership for Health, a smoking cessation intervention for smokers in the Childhood Cancer Survivors Study. The purpose of this article is to evaluate demographic, psychosocial, and cancer-related factors that are associated with smoking behavior and mediators of smoking cessation. PATIENTS AND METHODS: This study includes 796 smokers from the Childhood Cancer Survivors Study database who were diagnosed with cancer before the age of 21, had survived at least 5 years, and were at least 18 years of age at the time of the baseline survey. Correlates of smoking behaviors included smoking rate, number of recent quit attempts, and nicotine dependence; two key mediators of smoking cessation, readiness to quit smoking and self-efficacy, were also assessed. RESULTS: Participants smoked, on average, 14 cigarettes/day; 53.2% were nicotine dependent, and 58% had made at least one quit attempt in the past year. Smoking behaviors were primarily associated with demographic variables; mediators of cessation were primarily associated with age at cancer diagnosis and perceived vulnerability to smoking-related illnesses. Severity of psychologic symptoms was associated with increased smoking rate, high nicotine dependence, and low self-efficacy. Support for quitting was related to smoking rate, number of quit attempts, readiness to quit smoking, and self-efficacy. CONCLUSION: These findings indicate that many cancer survivors who smoke are receptive to smoking cessation interventions. Factors related to mediators of smoking cessation might be particularly good targets for intervention.     

INVITED REVIEW GASTROINTESTINAL MANIFESTATIONS IN PEDIATRIC AIDS

The pathologic changes in the gastrointestinal tract of children with AIDS are variable, clinically significant, and reflect multisystemic disease processes. Inflammation, changes in the lymphoid tissue, miscellaneous lesions, and tumors are documented in 58 patients in addition to cases reported in the literature. Cytomegalovirus infection of the gastrointestinal tract, associated with ulcerations, hemorrhage, perforation, and intestinal obstruction, carries a high morbidity and mortality, whereas the remaining infections are not life threatening. Special stains and electron micrographic examination are important to identify correctlycertain microorganisms such asmycobacterium avium intracellulare, cryptosporidia, and microsporidia. Lymphoproliferative changes of the gastrointestinal tract, a component of the generalized lymphoproliferative process, need to be characterized by tumor markers and cytogenetic studies. Within the miscellaneous lesions, AIDS associated arteriopathy can be complicated by intestinal ulceration and perforation. Both lymphomas and smooth muscle tumor in children with AIDS are related to Epstein-Barr virus infection. The smooth muscle tumors are frequently malignant and multiple.     

Clinical Classification as a Guide to Treatment of Sinusitis in Children

Evaluation of all 153 children undergoing CT scan of the paranasal sinuses for recalcitrant sinusitis symptoms between January 1988 and July 1992 was performed. Clinical categorization into groups of patients presenting with chronic sinusitis (CS) and recurrent acute sinusitis (RAS) was based upon pattern of disease and presentation. Clinical symptoms and signs, radiological examination, treatment, and outcome were compared between these distinct clinical groups. Eighty-two (55%) children were categorized as RAS and 68 (45%) as CS. Children with CS presented more frequently with a persistent cough, purulent nasal discharge, immune deficiency, and more severe mucosal disease on CT than children with RAS. Medical therapy successfully controlled the symptoms of sinusitis in 79 (96%) with RAS versus 27 (40%) with CS. Surgery was performed in 44 children: 3 (3.6%) with RAS versus 41 (60%) with CS, p<0.01. At a mean follow-up of 2.0 years, >80% of all the children were either asymptomatic or improved regardless of treatment modality. These data support the use of clinical classification as a guide to medical versus surgical therapy in children with sinusitis.     

Preterm Infants 30–36 Weeks' Gestation in Victoria — Where Should They Be Delivered?

Summary: There is little doubt that very preterm infants <30 weeks' gestation should be born in level-3 perinatal centres. For preterm infants 30–36 weeks' gestation, however, the optimum place of birth is not so clear-cut. The aims of this study of livebirths 30–36 weeks' gestational age born in Victoria were to determine: 1) the proportions delivered outside level-3 centres, and 2) for infants born outside level-3 centres, the proportions transferred after birth to a level-3 nursery in the first days after birth. Data on the number of livebirths 30–36 weeks' gestational age in Victoria in the 3 years 1994–1996, inclusive, were supplied by the Victorian Perinatal Data Collection Unit. Data were obtained from the Newborn Emergency Transport Service (NETS) on all transfers within the first 3 days after birth to a level-3 centre for infants born outside level-3 centres. For the 3 years 1994–1996 there were 11,375 livebirths 30–36 weeks' gestational age in Victoria. The proportion born outside a level-3 perinatal unit was 57.9% overall, and rose with increasing gestational age, from 10.9% at 30 weeks to 69.0% at 36 weeks. Of the 6,587 livebirths outside a level-3 centre, 808 (12.3%) were transferred within the first 3 days after birth by NETS to a level-3 centre, the proportions falling with increasing maturity, being 73.7%, 48.5%, 28.4%, 26.9%, 18.8%, 11.8%, and 7.0% at 30, 31, 32, 33, 34, 35, and 36 weeks, respectively. These data may help medical practitioners when determining the place of delivery for infants 30–36 weeks' gestation.     

Development of a diabetes care management curriculum in a family practice residency program.

Improving the quality of care for patients with chronic illness has become a high priority. Implementing training programs in disease management (DM) so the next generation of physicians can manage chronic illness more effectively is challenging. Residency training programs have no specific mandate to implement DM training. Additional barriers at the training facility include: 1) lack of a population-based perspective for service delivery; 2) weak support for self-management of illness; 3) incomplete implementation due to physician resistance or inertia; and 4) few incentives to change practices and behaviors. In order to overcome these barriers, training programs must take the initiative to implement DM training that addresses each of these issues. We report the implementation of a chronic illness management curriculum based on the Improving Chronic Illness Care (ICIC) Model. Features of this process included both patient care and learner objectives. These were: development of a multidisciplinary diabetes DM team; development of a patient registry; development of diabetes teaching clinics in the family practice center (nutrition, general management classes, and one-on-one teaching); development of a group visit model; and training the residents in the elements of the ICIC Model, ie, the community, the health system, self-management support, delivery system design, decision support, and clinical information systems. Barriers to implementing these curricular changes were: the development of a patient registry; buy-in from faculty, residents, clinic leadership, staff, and patients for the chronic care model; the ability to bill for services and maintain clinical productivity; and support from the health system key stakeholders for sustainability. Unique features of each training site will dictate differences in emphasis and structure; however, the core principles of the ICIC Model in enhancing self-management may be generalized to all sites.     

Glomerular Membranopathy in Children with IgA Nephropathy and Henoch Schönlein Purpura

We evaluated renal biopsies from 34 children with IgA nephropathy or Henoch Schönlein purpura to further characterize the ultrastructural features of the glomerular membranopathy that occurs in these disorders. Focal glomerular basement membrane damage was identified in 29 children and was severe in 4 of the children. Alterations included focal and segmental attenuation, splitting, duplications, and spike-like subepithelial protrusions of the lamina densa, along with saccular glomerular microaneurysms arising at the paramesangium. Those cases with extensive glomerular basement membrane lesions had either moderate or severe glomerular alterations apparent by light microscopy. Over half of the cases with glomerular membranopathy had immunohistological or ultrastructural evidence of focal peripheral glomerular capillary wall immune deposits and electron-dense deposits occurred at sites of glomerular basement membrane splitting. Despite the focal attenuation of the glomerular basement membrane, we did not identify any biopsy with findings of thin basement membrane disease. The glomerular basement membrane ultrastructural findings we describe are characteristic of IgA nephropathy and Henoch Schönlein purpura, are common in children with these disorders, and are similar to the ultrastructural alterations of the basement membrane that occur in other glomerulonephritides. These basement membrane injuries may be inflammatory cell or immune mediated but their pathogenesis requires further study.
