RESUMO

PURPOSE: We sought to understand the attitudes of individuals with abnormal breast imaging findings prompting a diagnostic breast biopsy toward donation of blood, excised tissue, or percutaneous biospecimens for research, and to understand medical oncologists' attitudes toward research biospecimen collection in this population. METHODS: We included individuals who presented to a single academic medical center for a clinically indicated, image-guided, percutaneous breast biopsy. We administered a survey prior to knowledge of biopsy results to assess willingness to consider, entirely for research purposes, donating blood or excess excised breast tissue, or having additional biospecimens (AB) obtained during a clinically indicated percutaneous biopsy. We also surveyed breast medical oncologists from National Cancer Institute-designated cancer centers to assess attitudes toward approaching patients for biospecimen research. RESULTS: Overall, 53/63 patients responded to the survey; 70% would consider donating blood, 85% would consider donating excess excised breast tissue, and 32% would consider having AB obtained during a clinically indicated biopsy. Main motivating factors for considering AB included contributing to scientific knowledge and return of study or biopsy results, whereas anxiety and the potential discomfort were the main dissuading factors. Among 191 medical oncologists, most were very comfortable (59.2%), or somewhat comfortable (32.5%) asking patients to have AB obtained during a clinically indicated breast biopsy. Medical oncologists reported hesitancy to refer a patient for AB due to potential pain/discomfort, and other procedure risks. CONCLUSIONS: Only one-third of individuals with breast imaging findings would consider consenting to AB during a diagnostic biopsy, whereas most were open to donating blood or excess excised breast tissue. Most medical oncologists would be comfortable asking patients to have AB obtained during the biopsy. Understanding patients' and oncologists' baseline attitudes may inform the design and approach to breast biospecimen-based research.

RESUMO

BACKGROUND: The objective of this study was to describe the perspective of patients with early breast cancer toward research biopsies. The authors hypothesized that more patients at academic sites than at community-based sites would be willing to consider these procedures. METHODS: In total, 198 patients with early stage breast cancer were recruited from 3 academic centers (n = 102) and from 1 community oncology practice (n = 96). The primary objective was to compare the proportion of patients willing to consider donating excess tissue biospecimens from surgery, from a clinically indicated breast biopsy, or from a research purposes-only biopsy (RPOB) between practice types. RESULTS: Most patients (93% at academic sites, 94% at the community oncology site) said they would consider donating excess tissue from surgery for research. One-half of patients from academic or community sites would consider donating tissue from a clinically indicated breast biopsy. On univariate analysis, significantly fewer patients from academic sites would consider an RPOB (22% at academic sites, 42% at the community site; P = .003); however, this difference was no longer significant on multivariate analysis (P = .96). Longer transportation times and unfavorable prior experiences were associated with less willingness to consider an RPOB on multivariate analysis. Significantly fewer patients from academic sites (14%) than from the community site (35%) would consider a research biopsy in a clinical trial (P = .04). Contributing to scientific knowledge, return of results, and a personal request by their physician were the strongest factors influencing patients' willingness to undergo research biopsies. CONCLUSIONS: The current results rejected the hypothesis that more patients with early breast cancer at academic sites would be willing to donate tissue biospecimens for research compared with those at community oncology sites. These findings identify modifiable factors to consider in biobanking studies and clinical trials.

RESUMO

PURPOSE: Sensorineural hearing loss (SNHL) is associated with intellectual and academic declines in children treated for embryonal brain tumors. This study expands upon existing research by examining core neurocognitive processes that may result in reading difficulties in children with treatment-related ototoxicity. PATIENTS AND METHODS: Prospectively gathered, serial, neuropsychological and audiology data for 260 children and young adults age 3 to 21 years (mean, 9.15 years) enrolled in a multisite research and treatment protocol, which included surgery, risk-adapted craniospinal irradiation (average risk, n = 186; high risk, n = 74), and chemotherapy, were analyzed using linear mixed models. Participants were assessed at baseline and up to 5 years after diagnosis and grouped according to degree of SNHL. Included were 196 children with intact hearing or mild to moderate SNHL (Chang grade 0, 1a, 1b, or 2a) and 64 children with severe SNHL (Chang grade 2b or greater). Performance on eight neurocognitive variables targeting reading outcomes (eg, phonemics, fluency, comprehension) and contributory cognitive processes (eg, working memory, processing speed) was analyzed. RESULTS: Participants with severe SNHL performed significantly worse on all variables compared with children with normal or mild to moderate SNHL (P ≤ .05), except for tasks assessing awareness of sounds and working memory. Controlling for age at diagnosis and risk-adapted craniospinal irradiation dose, performance on the following four variables remained significantly lower for children with severe SNHL: phonemic skills, phonetic decoding, reading comprehension, and speed of information processing (P ≤ .05). CONCLUSION: Children with severe SNHL exhibit greater reading difficulties over time. Specifically, they seem to struggle most with phonological skills and processing speed, which affect higher level skills such as reading comprehension.

RESUMO

BACKGROUND: Few researchers routinely disseminate results to participants; however, there is increasing acknowledgment that benefits of returning results outweigh potential risks. Our objective was to determine whether use of specific guidelines developed by the Children's Oncology Group (COG) when preparing a lay summary would aid in understanding results. Specifically, to determine if caregivers of childhood cancer survivors found a lay summary comprehensive, easy to understand, and helpful following participation in a computerized cognitive training program. METHODS: In a previous study, 68 childhood survivors of acute lymphoblastic leukemia or brain tumor with identified cognitive deficits were randomly assigned to participate in a computerized cognitive intervention or assigned to a wait list. Following conclusion of this study, participants' caregivers were contacted and provided with a summary of results based on COG guidelines and survey. Forty-three participants returned the surveys, examining caregivers' interpretation of the summary, reaction to the results, and information regarding preference for receiving results. RESULTS: Caregivers reported results as important (93%), helpful (93%), easy to understand (98%), and relevant to their child (91%). They interpreted the results as generally positive, with many caregivers endorsing satisfaction (84%); however, concern of long-term implications was expressed (25%). Most preferred receiving results through postal letter (88%) or email (47%). CONCLUSIONS: Benefits of returning research results to families appear to outweigh potential negative consequences. Returning results may help inform families when making future health care-related decisions. There is a great need to develop and assess the utility of guidelines for returning research results.

RESUMO

BACKGROUND: Childhood brain tumor diagnoses are stressful for families. Children diagnosed with craniopharyngioma (Cp) present with particularly challenging medical and cognitive problems due to tumor location and associated biophysiologic comorbidities. This study examined parental distress in a sample of families of patients with Cp treated with proton beam therapy to identify factors for targeting psychological intervention. PROCEDURE: Prior to (n = 96) and 1 year after (n = 73) proton therapy, parents of children diagnosed with Cp (9.81 ± 4.42 years at baseline; 49% male) completed a self-report measure of distress, the Brief Symptom Inventory (BSI). Children completed cognitive assessment measures at baseline; medical variables were extracted from the study database. RESULTS: At baseline, t-tests revealed parents reported higher levels of distress than normative expectations on Anxiety, Depression, Global Severity, and Positive Symptom Distress BSI scales (P < 0.05). Linear mixed effects models revealed parent report measures of child executive dysfunction and behavioral issues were more predictive of parental distress than patients' cognitive performance or medical status (P < 0.05). Models also revealed a significant reduction only in Anxiety over time (t = -2.19, P < 0.05). Extensive hypothalamic involvement at baseline predicted this reduction (P < 0.05). CONCLUSION: Parents experience significant distress before their child begins adjuvant therapy for Cp, though parental distress appears largely unrelated to medical complications and more related to parent perceptions of child cognitive difficulties (vs. child performance). Importantly, this may be explained by a negative parent reporting style among distressed parents. Knowledge of socio-emotional functioning in parents related to patient characteristics is important for optimization of psychological intervention.

RESUMO

PURPOSE: To explore patients' perspectives following anterior cruciate ligament rupture and subsequent reconstructive surgery. METHODS: A qualitative study design was employed, using validated questionnaires, interviews and general inductive methodology. Semi-structured interviews were conducted with five men and four women who had undergone an anterior cruciate ligament reconstruction in the past 6-36 months. Participants completed the Knee Osteoarthritis Outcome Score and the Tegner Activity Score. Descriptive statistics were used to analyze quantitative data. Interviews were recorded, transcribed and analyzed using the general inductive approach to develop key themes. RESULTS: Participants had not returned to pre-injury knee-related activity levels (Tegner score: 7 pre-injury; 4 current). The theme of a disruptive "journey" emerged with two sub-themes of "loss of identity" and "life at the present," influenced positively and negatively by "support systems" and experience with the "care pathway." This unequivocally negative experience resulted in irrevocable changes to their lives, reflected by current lower knee-related quality of life. CONCLUSIONS: Anterior cruciate ligament injury and rehabilitation thereof have a profound influence in the individual's identity. The results imply that a broader approach is needed within the rehabilitation process to address psychosocial factors, in addition to physical impairments and function. Implications for rehabilitation Anterior cruciate ligament rupture has a profound influence on patients' understanding of their individual identity. Support systems the patients have in place influence the patients' experience of the care pathway. Understanding psychosocial responses and implementing appropriate strategies and interventions for these may be critical for rehabilitation of these patients.

RESUMO

PURPOSE: This study examined the association between gender role orientation (GRO) and health-related quality of life (HRQOL) in youth, and how this relationship may differ between males and females as well as among African-American, White, and Hispanic individuals. GRO has been reported to influence serious health outcomes including cancer, heart disease, mental illness, and mortality rates. However, few studies have examined the link between GRO and health outcomes for children, even though gender identity is formed in childhood. METHODS: Data were examined from 4824 participants in the Healthy Passages™ project, a population-based survey of fifth-grade children in three US metropolitan areas. Children reported their own HRQOL using the PedsQL and degree of female, male, and androgynous GRO using the Children's Sex Role Inventory. RESULTS: Based on structural equations analysis, male GRO was positively associated with HRQOL for all racial/ethnic groups, regardless of sex, whereas female GRO was associated with better HRQOL for Hispanic and White females and poorer HRQOL for Hispanic males. Androgynous GRO was associated with better HRQOL among Hispanic and White females, but not males nor African-Americans of either sex. CONCLUSIONS: Racial/ethnic differences emerged for female and androgynous, but not male, GROs. Hispanic males are the only group for which GRO (female) was associated with poorer HRQOL. Future research should find ways to help youth overcome negative effects on health from gender beliefs and behavior patterns with sensitivity to racial/ethnic membership.

RESUMO

INTRODUCTION: Fulvestrant is an antiestrogen therapy with a unique mechanism of action. Unlike the selective estrogen receptor modulator tamoxifen, fulvestrant has no known estrogen agonist activity and is considered a pure antiestrogen. Its primary mechanism of action is thought to result from downregulation of the estrogen receptor (ER). Considerable data have demonstrated the efficacy of fulvestrant in postmenopausal women with ER-positive advanced breast cancer, both in the first-line setting and following disease progression on tamoxifen or aromatase inhibitors. Recent studies report improved benefit with alternative dosing strategies. At all administration schedules, fulvestrant has an excellent safety profile with no significant adverse effects. AREAS COVERED: This article provides a review of the mechanism of action of fulvestrant and the preclinical and clinical data evaluating its use as a form of endocrine therapy. The reader will gain insight into the pharmacologic properties of the drug and its role in the treatment of advanced hormone receptor-positive breast cancer in postmenopausal women. EXPERT OPINION: Based on data demonstrating the efficacy of fulvestrant, including prolonged clinical benefit in many patients, this well-tolerated antiestrogen is an important therapy for breast cancer. The optimal position of fulvestrant in the sequence of endocrine therapies for postmenopausal women and its role in combination regimens are not yet resolved.

RESUMO

OBJECTIVE: We have identified a large kindred with multiple endocrine neoplasia 2A (MEN 2A) due to a mutation at RET codon 609 that results in a cysteine to serine substitution, a mutation previously identified in only one case in the literature. We characterized the clinical phenotype of the kindred and the biochemical mechanism of this new mutation. PATIENTS AND DESIGN: The index case, a 42-year-old woman, presented with pheochromocytoma. We screened 29 family members for the presence of the mutation. Of the 15 mutation-positive family members, 11 agreed to undergo further evaluation by physical examination, calcium and pentagastrin-stimulated calcitonin levels, measurement of urinary metanephrines, adrenal imaging and serum calcium levels. Biochemical characterization of the mutation was by transient transfection of human neuroblastoma cells and Western blot analysis. RESULTS: This kindred demonstrated an inheritance pattern consistent with autosomal dominant pheochromocytoma. Strikingly, no clinically evident case of medullary thyroid cancer (MTC) was observed among mutation-positive family members. Thyroidectomy in six cases revealed C-cell hyperplasia in all and microscopic MTC in two cases. Transfection experiments using human neuroblastoma cells showed that the mutant RET, unlike the wild-type receptor, is constitutively phosphorylated in the absence of ligand, and thus resembles other previously characterized MEN 2A mutations. CONCLUSIONS: The identification of a new mutation causing a MEN 2A phenotype that features pheochromocytoma and the surprising absence of clinically apparent MTC has significant implications for carriers of this mutation and provides further insights into the genotype-phenotype correlation in MEN 2A.
