Patient-Centered Care and Healthcare Consumerism in Online Healthcare Service Advertisements: A Positioning Analysis.

Patient-centered care and healthcare consumerism are the two most dominant ideas about the relationship between patients and providers in the United States. To identify providers' positions between the two perspectives, we analyzed the content of direct-to-consumer healthcare service advertisements. The advertisements were collected in the state of Nevada (N = 323) and their landing pages were analyzed for provider attributes, patient experience features, and terms referring to patients and providers. The results showed that the advertisements fully embraced the notion of patient-centeredness by commonly claiming patient-centered care and frequently using the term "patient." The advertisements also contained multiple indicators of healthcare consumerism, although they avoided using the terms "consumer/customer/client" closely associated with consumerism. Contrary to the prominence of patient experience features, provider attributes were not common. An additional analysis of inter-specialty differences in advertising features confirmed the strong consumerism position of cosmetic surgery providers. Application of the healthcare service advertising analytic scheme developed for this study could help providers and healthcare administrators recognize how their advertising messages may reflect their values.

Comparing the attitudes of physicians and non-physicians toward communicating a patient's BRCA1 mutation to a first-degree relative against a patient's wishes.

Although genetic testing can be vastly informative, it creates a dilemma if a patient does not want to disclose an abnormal genetic test to at-risk relatives. A sample of 200 participants from Nevada (100 physicians, 100 non-physicians) completed an 11-item questionnaire asking demographic information, familiarity with genetics and genetic testing, and opinions about a physician's role in a hypothetical case in which a patient does not wish to communicate her BRCA1 mutation to her sister. Although most respondents did not think the physician should notify the sister against the patient's wishes, more non-physicians (40%) than physicians (23%) contended that the physician should do so (p = 0.0119). Most respondents from both groups agreed that the physician should not have the legal duty to notify the sister, would not be morally justified in sharing genetic test results with the sister, but should have the right to notify a patient's relatives if the disease is "serious, preventable, and treatable." More non-physicians than physicians agreed that physicians should have an educational requirement on how to communicate genetic test results to patients and their family (88% vs 65%, p = 0.0002). Most physicians (70%) reported a familiarity/strong familiarity with genetic testing compared to non-physicians (33%; p < 0.0001). Future qualitative research should assess physicians' understanding of issues surrounding familial communication of genetic test results. Educational interventions to facilitate effective communication to patients and families are needed and welcomed by most physicians. Discrepancies between the attitudes of physicians and patients or the public need to be better understood and addressed.

Mantle Cell Lymphoma Presenting as a Subcutaneous Mass of the Right Leg.

Mantle cell lymphoma (MCL) is a relatively rare B-cell non-Hodgkin lymphoma, typically presenting with extensive lymphadenopathy, bone marrow involvement, and splenomegaly. Extranodal sites can also be involved. We discuss a 73-year-old man whose MCL presented with a 6-month history of a subdermal mass of the right upper thigh and no systemic symptoms.

Outcome of patients with intracranial relapse enrolled on national Wilms Tumor Study Group clinical trials.

BACKGROUND: The occurrence of brain metastases (at diagnosis or at relapse) in patients with Wilms tumor is very rare. METHODS: We retrospectively reviewed the clinical characteristics of patients with Wilms tumor and relapse to the brain enrolled on the National Wilms Tumor Studies (NWTSs) 1-5. RESULTS: Intracranial relapse was documented in 47 patients (0.5%). Of the 45 patients with adequate data, 26 (58%) patients were male. Thirty-eight (84%) patients had favorable histology Wilms tumor. In 30 patients (67%), the appearance of intracranial disease was preceded by relapse at another site. Ten patients did not have any disease-directed therapy. Surgical resection was attempted in 15 patients; gross total resection was achieved in 11 patients. Twenty-nine patients received brain irradiation; the median dose was 3,000 cGy (range 1,080-4,000 cGy). Twenty-seven patients received chemotherapy. The 5-year overall survival from the time of intracranial relapse was 28.7% (95% confidence interval: 14.4-43.1%). Nine patients (all favorable histology Wilms tumor) were alive with a median follow-up from brain relapse of 140 months (range 35-381 months). All nine survivors received radiation therapy, eight received chemotherapy, and four underwent surgery (two gross total resection, two partial resection). The overall survival after brain metastases of the NWTS-5 patients was significantly higher than the overall survival of the NWTS 1-4 patients (P value = 0.029, log-rank test). CONCLUSIONS: Patients with Wilms tumor recurrence involving the brain may have durable survival, particularly those treated in recent years. Multimodality therapy including radiation and chemotherapy should be considered for these patients.

Management of adults with Wilms' tumor: recommendations based on international consensus.

Since Wilms' tumor occurs rarely in adults, there are no standard treatments available. Most adult patients will be diagnosed unexpectedly following nephrectomy for presumed renal cell carcinoma. Outcome for adults is inferior compared with children, although better results are reported when treated within pediatric trials. Multiple factors, including the unfamiliarity of adult oncologists and pathologists with Wilms' tumors, lack of standardized treatment and consequent delays in initiating the appropriate risk-adapted therapy, may contribute to the poor outcome. A standardized approach for the management of adult Wilms' tumors is proposed with the aim to limit treatment delay after surgery and encourage a uniform approach for this rare disease and thereby improve survival. These recommendations are based on discussions held with representatives of the renal tumor committees of the Society of Paediatric Oncology and Children's Oncology Group, and have been updated with a review of more recently published institutional and trial experience of adults treated on pediatric protocols. They provide a critical evaluation of the current evidence for the management of adult Wilms' tumors and propose details of how current pediatric therapeutic guidelines could be adapted for use in adults.

Candidate genes and potential targets for therapeutics in Wilms' tumour.

Wilms' tumour (WT) is the most common malignant renal tumour of childhood. During the past two decades or so, molecular studies carried out on biopsy specimens and tumour-derived cell lines have identified a multitude of chromosomal and epigenetic alterations in WT. In addition, a significant amount of evidence has been gathered to identify the genes and signalling pathways that play a defining role in its genesis, growth, survival and treatment responsiveness. As such, these molecules and mechanisms constitute potential targets for novel therapeutic strategies for refractory WT. In this report we aim to review some of the many candidate genes and intersecting pathways that underlie the complexities of WT biology.

Long-term outcomes for infants with very low risk Wilms tumor treated with surgery alone in National Wilms Tumor Study-5.

OBJECTIVE: To determine the event-free survival (EFS) and overall survival (OS) of children with very low risk Wilms tumor (VLRWT) treated with surgery only. BACKGROUND: Previous studies suggested that postoperative chemotherapy had not improved the prognosis of children with VLRWT. A total of 77 children <24 months of age with small (<550 g) Stage I favorable histology Wilms tumors were treated with surgery only. This study was closed based on stopping rules to ensure that the 2-year EFS was > or =90%. METHODS: A total of 77 children were assessed for EFS and OS. Of these patients, 21 enrolled at the time of closure were recalled, treated with dactinomycin and vincristine (regimen EE4A), and censored for analysis thereafter. About 111 children subsequently treated with EE4A were available for comparison. RESULTS: Median follow-up of surviving patients was 8.2 years for surgery only (range, 1.9-11.8 years) and 5.2 years for the EE4A group (range, 1.6-8.9 years). The estimated 5-year EFS for surgery only was 84% (95% confidence interval [CI]: 73%, 91%); for the EE4A patients it was 97% (95% CI: 92%, 99%, P = 0.002). One death was observed in each treatment group. The estimated 5-year OS was 98% (95% CI: 87%, 99%) for surgery only and 99% (95% CI: 94%, 99%) for EE4A (P = 0.70). CONCLUSION: The surgery-only EFS was lower than anticipated but, coupled with a much higher than anticipated salvage rate of the chemotherapy naive patients whose disease recurred, led to an observed long-term OS equivalent to that seen with 2-drug chemotherapy. This approach to the treatment of patients with VLRWT eliminates the toxic side-effects of chemotherapy for a large majority of patients. A follow-up study is underway to confirm these findings.

Extending the horizon for cell-based immunotherapy by understanding the mechanisms of action of photopheresis.

Most of the current cell-based immunotherapy protocols concentrate on immune stimulatory effects against certain pathogenic insults, such as cancer. In this article, a potential cell-based immunotherapeutic strategy to induce immune tolerance by infusion of apoptotic leukocytes is presented in conjunction with a review of newly understood mechanisms of action of photopheresis and relevant information about allogeneic transfusion-related immunomodulation. The scientific rationale is discussed by examining our understanding of the role of apoptosis in self-antigen tolerance, the interaction between apoptotic bodies and antigen-presenting cells, and the subsequent induction of T regulatory cells and clonal deletion of effector T cells. Previous data on transfusion-related immunomodulation are assembled to examine a possible link between the immunosuppressive effects obtained from photopheresis and those seen post allogeneic blood transfusion. Accumulating evidence appears to support the hypothesis that photopheresis and allogeneic blood transfusion may share a mechanism of action for the induction of immunosuppression, which suggests the potential of eliciting selective immune tolerance by giving the recipient a bolus of apoptotic cells. Such immunotherapy interventions could bring significant clinical benefit to patients undergoing transplant rejection or autoimmune-related disorders and deserve further investigation as well as validation studies.

Rethinking pediatric assent: from requirement to ideal.

Physician-investigators are required to obtain informed consent from adult participants in their studies. Inclusion of children in research legally requires informed permission of a child's parent or guardian. It is increasingly recognized that a child need not assume a passive role when included in research, but that his or her active involvement should be sought, as expressed by the child's assent to partake in clinical research. This article briefly explores the history of assent and the central role of assessing a child's understanding of research and preference for participating in decisions related to their care, as necessary components of meaningful assent.

Treatment of Wilms tumor relapsing after initial treatment with vincristine, actinomycin D, and doxorubicin. A report from the National Wilms Tumor Study Group.

OBJECTIVE: We evaluated the use of alternating cycles of cyclophosphamide/etoposide and carboplatin/etoposide in children entered on National Wilms Tumor Study (NWTS)-5 who were diagnosed between August 1, 1995 and May 31, 2002 and who relapsed after chemotherapy with vincristine, actinomycin D, and doxorubicin (VAD) and radiation therapy (DD-4A). PATIENTS AND METHODS: One hundred three patients who relapsed or had progressive disease after initial VAD chemotherapy and radiation therapy were registered on stratum C of the NWTS-5 Relapse protocol. Twelve patients were not evaluable: five due to insufficient data, six due to major protocol violations, and one for refusal of therapy. Among the 91 remaining patients, 14 with stage V Wilms tumor (WT), 1 with contralateral relapse, and 16 who did not achieve a complete response (CR) to the initial three-drug chemotherapy were not included in this analysis. Relapse treatment included alternating courses of the drug pairs cyclophosphamide/etoposide and carboplatin/etoposide, surgery, and radiation therapy. RESULTS: The outcomes of 60 patients were analyzed. The lung was the only site of relapse for 33 patients; other sites of relapse included the operative bed, the abdomen, and liver. Four-year event-free survival (EFS) and overall survival (OS) were 42.3 and 48.0% respectively for all patients and were 48.9 and 52.8% for those who relapsed in the lungs only. Thrombocytopenia was the most frequent toxicity. CONCLUSION: These results demonstrate that approximately one-half of children with unilateral WT who relapse after initial treatment with VAD and radiation therapy can be successfully retreated.

Topotecan is active against Wilms' tumor: results of a multi-institutional phase II study.

PURPOSE: A phase II study was conducted to evaluate the activity and safety of topotecan in pediatric patients with recurrent Wilms' tumor. PATIENTS AND METHODS: Patients with favorable histology Wilms' tumor (FHWT) and recurrence after at least one salvage chemotherapy regimen or with anaplastic histology Wilms' tumor (AHWT) in first or subsequent recurrence were eligible. Patients were stratified according to histology, with statistical considerations based on the FHWT stratum. Topotecan was administered intravenously over 30 minutes for 5 days on 2 consecutive weeks. Treatment dosages were adjusted to achieve a target area under the curve (AUC) of 80 +/- 10 ng/mL*h. Tumor responses were measured after two cycles of treatment. RESULTS: Thirty-seven patients (26 patients with FHWT) were enrolled and received a total of 94 cycles of topotecan (range, one to six cycles). The median topotecan dosage required to achieve the target AUC was 1.8 mg/m2 (range, 0.7 to 3.2 mg/m2). Of 25 assessable patients with FHWT, 12 had partial response (PR), six had stable disease (SD), and seven had progressive disease (PD), for an overall response rate of 48% (95% CI, 27.8% to 68.7%). Of 11 assessable patients with AHWT, two had PR, one had SD, and eight had PD. The main toxicities were grade 3 and 4 neutropenia (median duration, 13 days) and thrombocytopenia (median duration, 7.5 days). CONCLUSION: Topotecan administered on a protracted schedule is active against recurrent FHWT. Inclusion of topotecan in front-line clinical trials for patients with recurrent Wilms' tumor should be considered.

Treatment of Wilms tumor relapsing after initial treatment with vincristine and actinomycin D: a report from the National Wilms Tumor Study Group.

PURPOSE: NWTS-5 was a multi-institutional clinical trial for patients less than 16 years of age at diagnosis with specific renal neoplasms who were diagnosed between August 1, 1995 and May 31, 2002. A uniform approach to the treatment of patients with relapse was employed. PATIENTS AND METHODS: Seventy-two patients who relapsed after immediate nephrectomy (stages I and II), initial chemotherapy with vincristine (VCR) and actinomycin D and no radiation therapy were registered on stratum B of the NWTS-5 relapse protocol. Four patients were not evaluable: one due to insufficient data and three due to major protocol violations. Among the 68 remaining patients, one who was 19 years of age at initial diagnosis of Wilms tumor, five with bilateral Wilms tumor at diagnosis, three who developed a contralateral relapse, and one with persistent disease were not included in this analysis. Relapse treatment included surgical excision, when feasible, radiation therapy and alternating courses of VCR, doxorubicin and cyclophosphamide and etoposide and cyclophosphamide. RESULTS: The outcomes of 58 patients were analyzed. The lung was the only site of relapse for 31 patients. Event-free survival 4 years after relapse was 71.1% and 4-year overall survival was 81.8% for all patients and were 67.8 and 81.0% for those who relapsed only to their lungs. The most frequent toxicities were hematological. CONCLUSIONS: These results demonstrate that a significant proportion of children with Wilms tumor who relapse after initial treatment with VCR and actinomycin D can be successfully re-treated.
