Approach for reporting master protocol study designs on ClinicalTrials.gov: qualitative analysis.

OBJECTIVE: To describe an approach for reporting master protocol research programs (MPRPs) that is consistent with existing good reporting practices and that uses structured information to convey the overall master protocol and design of each substudy. DESIGN: Qualitative analysis. DATA SOURCES: ClinicalTrials.gov trial registry. MAIN OUTCOME MEASURES: Established goals and related practices of the trial reporting system were outlined, examples and key characteristics of MPRPs were reviewed, and specific challenges in registering and reporting summary results to databases designed for traditional clinical trial designs that rely on a model of one study per protocol were identified. RESULTS: A reporting approach is proposed that accommodates the complex study design of MPRPs and their results. This approach involves the use of separate registration records for each substudy within one MPRP protocol (with potential exceptions noted). CONCLUSIONS: How the proposed approach allows for clear, descriptive, structured information about each substudy's prespecified design and supports timely reporting of results after completion of each substudy is described and illustrated. Although the focus is on reporting to ClinicalTrials.gov, the approach supports broader application across trial registries and results databases. This paper is intended to stimulate further discussion of this approach among stakeholders, build awareness about the need to improve reporting of MPRPs, and encourage harmonization across trial registries globally.

Patterns of Enrollment in Cancer Treatment Trials During the COVID-19 Pandemic at National Cancer Institute-Designated Cancer Centers.

ABSTRACT: The COVID-19 pandemic posed unprecedented strain on enrollment to cancer clinical trials and their conduct. Here, we highlight an analysis using information from the National Cancer Institute (NCI) Clinical Trials Reporting Program database to describe enrollment patterns to interventional cancer treatment trials at NCI-Designated Cancer Centers during the pandemic. Enrollment to cancer treatment trials at NCI-Designated Cancer Centers decreased precipitously early in the pandemic and has not yet fully returned to the 2019 baseline as of mid-2021. We discuss possible reasons for this and how some of the changes in clinical trial conduct implemented during the pandemic may become part of the standard conduct of NCI-supported clinical trials and broaden access to trials.

Characteristics of Breast Ducts in Normal-Risk and High-risk Women and Their Relationship to Ductal Cytologic Atypia.

Breast ductal cytologic atypia is an important risk factor for sporadic breast cancer. Characterization of the associated normal breast tissue is needed to develop additional methods of risk assessment and new targets for breast cancer prevention. We conducted a prospective clinical trial evaluating women at normal-risk or at high-risk for sporadic breast cancer. Breast ductal cells were collected and studied cytologically and by gene expression profiling, and breast ductal architectural changes were studied by breast ductal endoscopy (BDE) and breast MRI. One hundred and forty subjects were studied, 70 at high risk (RR, 2.0-4.6) and 70 at normal risk. Cytologic atypia was present in 22.9% of high-risk and 25.7% of normal-risk subjects. Ductal endoscopy was performed in 89 subjects and revealed benign intraductal abnormalities, primarily intraductal fibrous webbing suggesting chronic inflammation, in 40.4% of high-risk and 5.4% of normal-risk subjects, respectively (P 2 = 0.0002). Two high-risk subjects with atypia and no normal-risk subjects with atypia developed invasive breast cancer. Gene expression profiling of ductal cells showed comparable gene expression profiles without enriched expression of previously defined oncogenic signatures in subjects with cellular atypia compared with those without atypia, and in high-risk subjects compared with normal-risk subjects (FDR > 0.5). Cytologic ductal atypia in normal-risk subjects does not appear to be of clinical significance. Atypia in women at high risk may be associated with benign and malignant breast ductal abnormalities; these characteristics of high-risk ductal cells may not be reflected in gene expression profiles.

The National Cancer Institute and Department of Veterans Affairs Interagency Group to Accelerate Trials Enrollment (NAVIGATE): A federal collaboration to improve cancer care.

Cancer clinical trials represent an important option for patients with a diagnosis of cancer and the clinician-investigators involved in their care who seek options for their disease. For all who are impacted by cancer, these studies offer opportunities for greater learning. Conducting these important studies involves several challenges, including recruiting eligible participants. To address barriers that arise over the course of these activities, the Department of Veterans Affairs (VA) and National Cancer Institute (NCI) have partnered to increase Veteran participation in oncology clinical trials. This initiative, the NCI And VA Interagency Group to Accelerate Trials Enrollment, or NAVIGATE, is focused on addressing recruitment across the VA healthcare system and finding systematic solutions related to activating, recruiting for and conducting oncology clinical trials at VA Medical Centers. Additional goals include (1) establishing a sustainable network that can serve as a model for other VA sites interested in doing cancer clinical trials, (2) recruitment of minority patients, and (3) developing best practices and policies that can be deployed across the VA healthcare system. In this manuscript, we describe the scope, organization, activities, and future directions of NAVIGATE while also highlighting key needs for successfully conducting cancer clinical trials within the VA system. This partnership between 2 large federal agencies with a shared commitment to improving cancer care may provide lessons to others who are also dedicated to helping those affected by the disease.

Research Priorities, Measures, and Recommendations for Assessment of Tobacco Use in Clinical Cancer Research.

There is strong evidence that cigarette smoking causes adverse outcomes in people with cancer. However, more research is needed regarding those effects and the effects of alternative tobacco products and of secondhand smoke, the effects of cessation (before diagnosis, during treatment, or during survivorship), the biologic mechanisms, and optimal strategies for tobacco dependence treatment in oncology. Fundamentally, tobacco is an important source of variation in clinical treatment trials. Nevertheless, tobacco use assessment has not been uniform in clinical trials. Progress has been impeded by a lack of consensus regarding tobacco use assessment suitable for cancer patients. The NCI-AACR Cancer Patient Tobacco Use Assessment Task Force identified priority research areas and developed recommendations for assessment items and timing of assessment in cancer research. A cognitive interview study was conducted with 30 cancer patients at the NIH Clinical Center to evaluate and improve the measurement items. The resulting Cancer Patient Tobacco Use Questionnaire (C-TUQ) includes "Core" items for minimal assessment of tobacco use at initial and follow-up time points, and an "Extension" set. Domains include the following: cigarette and other tobacco use status, intensity, and past use; use relative to cancer diagnosis and treatment; cessation approaches and history; and secondhand smoke exposure. The Task Force recommends that assessment occur at study entry and, at a minimum, at the end of protocol therapy in clinical trials. Broad adoption of the recommended measures and timing protocol, and pursuit of the recommended research priorities, will help us to achieve a clearer understanding of the significance of tobacco use and cessation for cancer patients.

An Improved Breast Epithelial Sampling Method for Molecular Profiling and Biomarker Analysis in Women at Risk for Breast Cancer.

BACKGROUND: There is a strong need to define the molecular changes in normal at-risk breast epithelium to identify biomarkers and new targets for breast cancer prevention and to develop a molecular signature for risk assessment. Improved methods of breast epithelial sampling are needed to promote whole-genome molecular profiling, increase ductal epithelial cell yield, and reduce sample cell heterogeneity. METHODS: We developed an improved method of breast ductal sampling with ductal lavage through a 22-gauge catheter and collection of ductal samples with a microaspirator. Women at normal risk or increased risk for breast cancer were studied. Ductal epithelial samples were analyzed for cytopathologic changes, cellular yield, epithelial cell purity, quality and quantity of DNA and RNA, and use in multiple downstream molecular applications. RESULTS: We studied 50 subjects, including 40 subjects at normal risk for breast cancer and 37 subjects with non-nipple aspirate fluid-yielding ducts. This method provided multiple 1.0 mL samples of high ductal epithelial cell content (median ≥8 samples per subject of ≥5,000 cells per sample) with 80%-100% epithelial cell purity. Extraction of a single intact ductal sample (fluid and cells) or the separate frozen cellular component provided DNA and RNA for multiple downstream studies, including quantitative reverse transcription- polymerase chain reaction (PCR) for microRNA, quantitative PCR for the human telomerase reverse transcriptase gene, whole-genome DNA amplification, and array comparative genomic hybridization analysis. CONCLUSION: An improved breast epithelial sampling method has been developed, which should significantly expand the acquisition and biomarker analysis of breast ductal epithelium in women at risk for breast cancer.

Relationships between computer-extracted mammographic texture pattern features and BRCA1/2 mutation status: a cross-sectional study.

INTRODUCTION: Mammographic density is similar among women at risk of either sporadic or BRCA1/2-related breast cancer. It has been suggested that digitized mammographic images contain computer-extractable information within the parenchymal pattern, which may contribute to distinguishing between BRCA1/2 mutation carriers and non-carriers. METHODS: We compared mammographic texture pattern features in digitized mammograms from women with deleterious BRCA1/2 mutations (n = 137) versus non-carriers (n = 100). Subjects were stratified into training (107 carriers, 70 non-carriers) and testing (30 carriers, 30 non-carriers) datasets. Masked to mutation status, texture features were extracted from a retro-areolar region-of-interest in each subject's digitized mammogram. Stepwise linear regression analysis of the training dataset identified variables to be included in a radiographic texture analysis (RTA) classifier model aimed at distinguishing BRCA1/2 carriers from non-carriers. The selected features were combined using a Bayesian Artificial Neural Network (BANN) algorithm, which produced a probability score rating the likelihood of each subject's belonging to the mutation-positive group. These probability scores were evaluated in the independent testing dataset to determine whether their distribution differed between BRCA1/2 mutation carriers and non-carriers. A receiver operating characteristic analysis was performed to estimate the model's discriminatory capacity. RESULTS: In the testing dataset, a one standard deviation (SD) increase in the probability score from the BANN-trained classifier was associated with a two-fold increase in the odds of predicting BRCA1/2 mutation status: unadjusted odds ratio (OR) = 2.00, 95% confidence interval (CI): 1.59, 2.51, P = 0.02; age-adjusted OR = 1.93, 95% CI: 1.53, 2.42, P = 0.03. Additional adjustment for percent mammographic density did little to change the OR. The area under the curve for the BANN-trained classifier to distinguish between BRCA1/2 mutation carriers and non-carriers was 0.68 for features alone and 0.72 for the features plus percent mammographic density. CONCLUSIONS: Our findings suggest that, unlike percent mammographic density, computer-extracted mammographic texture pattern features are associated with carrying BRCA1/2 mutations. Although still at an early stage, our novel RTA classifier has potential for improving mammographic image interpretation by permitting real-time risk stratification among women undergoing screening mammography.

Implementation of timeline reforms speeds initiation of National Cancer Institute-sponsored trials.

BACKGROUND: The National Cancer Institute (NCI) organized the Operational Efficiency Working Group in 2008 to develop recommendations for improving the speed with which NCI-sponsored clinical trials move from the idea stage to a protocol open to patient enrollment. METHODS: Given the many stakeholders involved, the Operational Efficiency Working Group advised a multifaceted approach to mobilize the entire research community to improve their business processes. New staff positions to monitor progress, protocol-tracking Web sites, and strategically planned conference calls were implemented. NCI staff and clinical teams at Cooperative Groups and Cancer Centers strived to achieve new target timelines but, most important, agreed to abide by absolute deadlines. For phase I-II studies and phase III studies, the target timelines are 7 months and 10 months, whereas the absolute deadlines were set at 18 and 24 months, respectively. Trials not activated by the absolute deadline are automatically disapproved. RESULTS: The initial experience is encouraging and indicates a reduction in development times for phase I-II studies from the historical median of 541 days to a median of 442 days, an 18.3% decrease. The experience with phase III studies to date, although more limited (n = 25), demonstrates a 45.7% decrease in median days. CONCLUSIONS: Based upon this progress, the NCI and the investigator community have agreed to reduce the absolute deadlines to 15 and 18 months for phase I-II and III trials, respectively. Emphasis on initiating trials rapidly is likely to help reduce the time it takes for clinical trial results to reach patients in need of new treatments.

Single-cell genetic analysis of ductal carcinoma in situ and invasive breast cancer reveals enormous tumor heterogeneity yet conserved genomic imbalances and gain of MYC during progression.

Ductal carcinoma in situ (DCIS) is a precursor lesion of invasive ductal carcinoma (IDC) of the breast. To understand the dynamics of genomic alterations in this progression, we used four multicolor fluorescence in situ hybridization probe panels consisting of the oncogenes COX2, MYC, HER2, CCND1, and ZNF217 and the tumor suppressor genes DBC2, CDH1, and TP53 to visualize copy number changes in 13 cases of synchronous DCIS and IDC based on single-cell analyses. The DCIS had a lower degree of chromosomal instability than the IDC. Despite enormous intercellular heterogeneity in DCIS and IDC, we observed signal patterns consistent with a nonrandom distribution of genomic imbalances. CDH1 was most commonly lost, and gain of MYC emerged during progression from DCIS to IDC. Four of 13 DCISs showed identical clonal imbalances in the IDCs. Six cases revealed a switch, and in four of those, the IDC had acquired a gain of MYC. In one case, the major clone in the IDC was one of several clones in the DCIS, and in another case, the major clone in the DCIS became one of the two major clones in the IDC. Despite considerable chromosomal instability, in most cases the evolution from DCIS to IDC is determined by recurrent patterns of genomic imbalances, consistent with a biological continuum.

Interphase cytogenetics of sputum cells for the early detection of lung carcinogenesis.

This perspective on Varella-Garcia et al. (beginning on p. 447 in this issue of the journal) examines the role of interphase fluorescence in situ hybridization for the early detection of lung cancer. This work is an important step toward identifying and validating a molecular marker in sputum samples for lung cancer early detection and highlights the value of establishing cohort studies with biorepositories of samples collected from participants followed over time for disease development.

Mammographic density does not differ between unaffected BRCA1/2 mutation carriers and women at low-to-average risk of breast cancer.

Elevated mammographic density (MD) is one of the strongest risk factors for sporadic breast cancer. Epidemiologic evidence suggests that MD is, in part, genetically determined; however, the relationship between MD and BRCA1/2 mutation status is equivocal. We compared MD in unaffected BRCA1/2 mutation carriers enrolled in the U.S. National Cancer Institute's Clinical Genetics Branch's Breast Imaging Study (n = 143) with women at low-to-average breast cancer risk enrolled in the same study (n = 29) or the NCI/National Naval Medical Center's Susceptibility to Breast Cancer Study (n = 90). The latter were BRCA mutation-negative members of mutation-positive families or women with no prior breast cancer, a Pedigree Assessment Tool score <8 (i.e., low risk of a hereditary breast cancer syndrome) and a Gail score <1.67. A single experienced mammographer measured MD using a computer-assisted thresholding method. We collected standard breast cancer risk factor information in both studies. Unadjusted mean percent MD was higher in women with BRCA1/2 mutations compared with women at low-to-average breast cancer risk (37.3% vs. 33.4%; P = 0.04), but these differences disappeared after adjusting for age and body mass index (34.9% vs. 36.3%; P = 0.43). We explored age at menarche, nulliparity, age at first birth, menopausal status, number of breast biopsies, and exposure to exogenous hormonal agents as potential confounders of the MD and BRCA1/2 association. Taking these factors into account did not significantly alter the results of the age/body mass index-adjusted analysis. Our results do not provide support for an independent effect of BRCA1/2 mutation status on mammographic density.

The prioritization of cancer antigens: a national cancer institute pilot project for the acceleration of translational research.

The purpose of the National Cancer Institute pilot project to prioritize cancer antigens was to develop a well-vetted, priority-ranked list of cancer vaccine target antigens based on predefined and preweighted objective criteria. An additional aim was for the National Cancer Institute to test a new approach for prioritizing translational research opportunities based on an analytic hierarchy process for dealing with complex decisions. Antigen prioritization involved developing a list of "ideal" cancer antigen criteria/characteristics, assigning relative weights to those criteria using pairwise comparisons, selecting 75 representative antigens for comparison and ranking, assembling information on the predefined criteria for the selected antigens, and ranking the antigens based on the predefined, preweighted criteria. Using the pairwise approach, the result of criteria weighting, in descending order, was as follows: (a) therapeutic function, (b) immunogenicity, (c) role of the antigen in oncogenicity, (d) specificity, (e) expression level and percent of antigen-positive cells, (f) stem cell expression, (g) number of patients with antigen-positive cancers, (h) number of antigenic epitopes, and (i) cellular location of antigen expression. None of the 75 antigens had all of the characteristics of the ideal cancer antigen. However, 46 were immunogenic in clinical trials and 20 of them had suggestive clinical efficacy in the "therapeutic function" category. These findings reflect the current status of the cancer vaccine field, highlight the possibility that additional organized efforts and funding would accelerate the development of therapeutically effective cancer vaccines, and accentuate the need for prioritization.

Ductal lavage in women from BRCA1/2 families: is there a future for ductal lavage in women at increased genetic risk of breast cancer?

PURPOSE: Ductal lavage has been used for risk stratification and biomarker development and to identify intermediate endpoints for risk-reducing intervention trials. Little is known about patient characteristics associated with obtaining nipple aspirate fluid (NAF) and adequate cell counts (> or =10 cells) in ductal lavage specimens from BRCA mutation carriers. METHODS: We evaluated patient characteristics associated with obtaining NAF and adequate cell counts in ductal lavage specimens from the largest cohort of women from BRCA families yet studied (BRCA1/2 = 146, mutation-negative = 23, untested = 2). Fisher's exact test was used to evaluate categorical variables; Wilcoxon nonparametric test was used to evaluate continuous variables associated with NAF or ductal lavage cell count adequacy. Logistic regression was used to identify independent correlates of NAF and ductal lavage cell count adequacy. RESULTS: From 171 women, 45 (26%) women had NAF and 70 (41%) women had ductal lavage samples with > or =10 cells. Postmenopausal women with intact ovaries compared with premenopausal women [odds ratio (OR), 4.8; P = 0.03] and women without a prior breast cancer history (OR, 5.2; P = 0.04) had an increased likelihood of yielding NAF. Having breast-fed (OR, 3.4; P = 0.001), the presence of NAF before ductal lavage (OR, 3.2; P = 0.003), and being premenopausal (OR, 3.0; P = 0.003) increased the likelihood of ductal lavage cell count adequacy. In known BRCA1/2 mutation carriers, only breast-feeding (OR, 2.5; P = 0.01) and the presence of NAF (OR, 3.0; P = 0.01) were independent correlates of ductal lavage cell count adequacy. CONCLUSIONS: Ductal lavage is unlikely to be useful in breast cancer screening among BRCA1/2 mutation carriers because the procedure fails to yield adequate specimens sufficient for reliable cytologic diagnosis or to support translational research activities.

Recruitment to a physical activity intervention study in women at increased risk of breast cancer.

BACKGROUND: Physical activity is being studied as a breast cancer prevention strategy. Women at risk of breast cancer report interest in lifestyle modification, but recruitment to randomized physical activity intervention studies is challenging. METHODS: We conducted an analysis of recruitment techniques used for a prospective, randomized pilot study of physical activity in women at risk of breast cancer. We evaluated differences in proportion of eligible patients, enrolled patients, and successful patients identified by each individual recruitment method. The Fisher-Freeman-Halton test (an extension of Fisher's exact test from 2 x 2 tables to general row by column tables) was used to compare the success of different recruitment strategies. RESULTS: We received 352 inquiries from women interested in participating, of whom 171 (54%) were eligible. Ninety-nine women completed a baseline activity evaluation, and 58 (34% of eligible; 16% of total inquiries) were randomized. Recruitment methods fell into three broad categories: media techniques, direct contact with potential participants, and contacts with health care providers. Recruitment strategies differed significantly in their ability to identify eligible women (p = 0.01), and women who subsequently enrolled in the study (p = 0.02). CONCLUSION: Recruitment techniques had varying success. Our data illustrate the challenges in recruiting to behavior modification studies, and provide useful information for tailoring future recruitment efforts for lifestyle intervention trials.

Randomized comparison of phone versus in-person BRCA1/2 predisposition genetic test result disclosure counseling.

PURPOSE: This study evaluated whether phone results were equivalent to in-person result disclosure for individuals undergoing BRCA1/2 predisposition genetic testing. METHODS: A total of 111 of 136 subjects undergoing education and counseling for BRCA1/2 predisposition genetic testing agreed to randomization to phone or in-person result disclosure. Content and format for both sessions were standardized. Data from the State-Trait Anxiety Inventory and the Psychological General Well-Being index were collected at baseline and then again at 1 week and 3 months after disclosure of test results. Baseline measures were administered after the following had occurred: counseling/education session had been conducted, informed consent had been obtained, and decision to be tested had been made. Satisfaction and cost assessments were administered after the result session. At 1 week, participants were asked their preferred method of result disclosure. RESULTS: There were no differences in anxiety and general well-being measures between 50 phone and 52 in-person results disclosure. Both groups reported similar rates of satisfaction with services. Among those with a preference, 77% preferred the notification method assigned. There was a statistically significant preference for phone results among the 23% who did not prefer the method assigned. Greater costs were associated with in-person result disclosure. CONCLUSIONS: These data suggest that phone results are a reasonable alternative to traditional in-person BRCA1/2 genetic test disclosure without any negative psychologic outcomes or compromise in knowledge. However, further study is needed in a more clinically representative population to confirm these findings.

The inhibition and treatment of breast cancer with poly (ADP-ribose) polymerase (PARP-1) inhibitors.

BRCA1 and BRCA2 mutations are responsible for most familial breast carcinomas. Recent reports carried out in non-cancerous mouse BRCA1- or BRCA2-deficient embryonic stem (ES) cells, and hamster BRCA2-deficient cells have demonstrated that the targeted inhibition of poly(ADP-ribose) polymerase (PARP-1) kills BRCA mutant cells with high specificity. Although these studies bring hope for BRCA mutation carriers, the effectiveness of PARP-1 inhibitors for breast cancer remains elusive. Here we present the first in vivo demonstration of PARP-1 activity in BRCA1-deficient mammary tumors and describe the effects of PARP-1 inhibitors (AG14361, NU1025, and 3-aminobenzamide) on BRCA1-deficient ES cells, mouse and human breast cancer cells. AG14361 was highly selective for BRCA1-/- ES cells; however, NU1025 and 3-aminobenzamide were relatively non-selective. In allografts of naïve ES BRCA1-/- cells there was either partial or complete remission of tumors. However, in allografts of mouse, BRCA1-/- mammary tumors, there was no tumor regression or remission although a partial inhibition of tumor growth was observed in both the BRCA1-/- and BRCA1+/+ allografts. In human tumor cells, PARP-1 inhibitors showed no difference in vitro in limiting the growth of mammary tumors irrespective of their BRCA1 status. These results suggest that PARP-1 inhibitors may non-specifically inhibit the growth of mammary tumors.

Effects of raloxifene on circulating prolactin and estradiol levels in premenopausal women at high risk for developing breast cancer.

BACKGROUND: Prolactin is a peptide hormone necessary for normal breast development that may contribute to breast tumorigenesis. Estrogen is a significant positive regulator of prolactin synthesis; therefore, raloxifene, a selective estrogen receptor modulator under study as a breast cancer prevention agent, may modulate both estradiol and prolactin levels by inhibiting estradiol from binding to its receptor. METHODS: Premenopausal women at increased risk for invasive breast cancer participated in a pilot chemoprevention trial and were given 60 mg raloxifene daily for 24 months. Fasting serum samples collected at baseline and after 12 months on drug were used to measure circulating prolactin, estradiol, and sex hormone binding globulin (SHBG) levels. RESULTS: Of the 27 subjects who completed 12 months of raloxifene, 23 had paired prolactin samples, and 20 had paired estradiol and SHBG samples. Prolactin levels did not significantly change with raloxifene treatment, but SHBG levels increased (mean change = 7.3 nmol/L; P = 0.0001; 95% confidence interval, 3.9-10.7). Estradiol (mean change = 42 pg/mL; P = 0.048; 95% confidence interval, 1-84 pg/mL) levels were elevated when comparing 15 of the 20 women with paired estradiol measurements who also had both of these samples taken during the early follicular phase of the menstrual cycle. CONCLUSIONS: This report is the first to examine the long-term effects of raloxifene on prolactin, estradiol, and SHBG levels in premenopausal women who are also at increased risk for developing invasive breast cancer. Raloxifene had no significant effect on prolactin levels but did increase estradiol and SHBG measurements.

High prevalence of occult endobronchial malignancy in high risk patients with moderate sputum atypia.

Early stage radiographically occult lung cancer has a high cure rate, but comprises a small fraction of all lung cancer. Abnormal sputum cytology is one indication for bronchoscopy in patients with chest imaging that is not suspicious for lung cancer. While there is good evidence that sputum cytologic findings of carcinoma, carcinoma in situ or severe atypia predict high rates of diagnosis of lung cancer, less is known of the frequency in which lung cancer is diagnosed in bronchoscopies carried out for the indication of moderate sputum atypia. One small series, published in abstract form only, reported an 8% rate of diagnosis of lung cancer in subjects bronchoscoped for moderate atypia. We tested the hypothesis that moderate sputum atypia is an indicator of occult central airway cancer in a retrospective analysis of a group of high risk subjects, defined as current or former smokers with >30 pack-years tobacco smoking and airflow obstruction with moderate atypia sputum cytology. Seventy-nine such subjects with no evidence of malignancy on chest radiograph at the time bronchoscopy was scheduled underwent white light and autofluorescence bronchoscopy. Lung cancer was found in five subjects; three had invasive squamous cell carcinomas and two had carcinoma in situ. Seven additional subjects had severe dysplasia found on endobronchial biopsy. Moderate sputum atypia may be an important marker of risk for occult endobronchial malignancy in high risk subjects.

Randomized comparison of group versus individual genetic education and counseling for familial breast and/or ovarian cancer.

PURPOSE: An efficient approach to education and counseling before BRCA1 and BRCA2 mutation testing is necessary for effective utilization of testing in the community. Education and counseling, when delivered individually, are limited by a shortage of trained health care providers as well as by financial and time constraints. The purpose of this study was to determine whether pretest education and counseling for breast cancer genetics in a group setting is equivalent to that provided on an individual basis. PATIENTS AND METHODS: One hundred forty-two patients at high risk for harboring a BRCA mutation were randomly assigned to group or individual education and counseling sessions. Group education was followed by brief individual counseling. Knowledge and Impact of Events Scales (IES) were administered at baseline and after education and counseling and at 1 week and 3, 6, and 12 months. Satisfaction with education and counseling was measured at completion of the session. Preferred method of education and counseling was solicited at 3 months. RESULTS: There was no difference in knowledge or IES scores between groups. When stratified by genetic test results, knowledge scores showed no difference. Regardless of group, post-test IES scores in patients with positive results were higher than patients with negative or uninformative results but returned to baseline by 12 months. Participants were equally satisfied with either method they were assigned. Significantly more time was spent per patient in individual sessions (1.25 hours) than in group education (0.74 hours). CONCLUSION: Our data suggest that group education and counseling may confer similar benefits compared with traditional individual sessions. Additional investigation of this approach in larger numbers of patients is warranted.
