Lung Cancer Patients' and Caregivers' Satisfaction With Multidisciplinary Versus Serial Care in a Community Healthcare Setting: A Prospective Comparative-Effectiveness Cohort Study.

BACKGROUND: Multidisciplinary Care is recommended for complex oncologic conditions. We compared lung cancer patients' and caregivers' satisfaction with Multidisciplinary Care to routine, serial care. MATERIALS AND METHODS: We analyzed validated surveys administered at baseline, 3 and 6 months to patients and their caregivers enrolled in a prospective cohort comparative-effectiveness study of Multidisciplinary versus Serial Care (clinicaltrials.gov NCT02123797). Multivariate mixed linear models examined the cross-group differences, time-related variances, and how interaction between groups and time-periods influenced satisfaction. RESULTS: Compared to serial care (N = 297), the Multidisciplinary Care cohort (N = 159), was older (69 vs. 66 years), had earlier clinical stage (41% vs. 33% stage I/II), and less severe symptoms (45% vs. 35% asymptomatic). Demographic and social-economic characteristics of caregivers (N = 99 for Multidisciplinary and 123 for Serial Care, respectively) were similar. Multidisciplinary Care patients and caregivers were more likely to perceive their care to be better than that of other patients (p < .01). Although Serial Care patients and caregivers expressed greater satisfaction with their treatment plan (p < .01 patients, p = 0.04 caregivers), Multidisciplinary Care patients showed greater improvement at 6-months (p < .01). Multidisciplinary Care patients and caregivers reported better overall satisfaction with team members (p < .01) while Serial Care patients had greater improvement in their satisfaction with team members at 6-months (p = .04). Multidisciplinary Care patients perceived more financial burden at 6-months compared to Serial Care patients (p = .04). CONCLUSION: Patient-caregiver dyads had mixed perceptions of their care experience. Recipients of Multidisciplinary Care perceived better experience with care and team members; Serial Care recipients expressed greater satisfaction with their treatment plan.

Prospective Comparative Effectiveness Trial of Multidisciplinary Lung Cancer Care Within a Community-Based Health Care System.

PURPOSE: Multidisciplinary lung cancer care is assumed to improve care delivery by increasing transparency, objectivity, and shared decision making; however, there is a lack of high-level evidence demonstrating its benefits, especially in community-based health care systems. We used implementation and team science principles to establish a colocated multidisciplinary lung cancer clinic in a large community-based health care system and evaluated patient experience and outcomes within and outside this clinic. METHODS: We conducted a prospective frequency-matched comparative effectiveness study (ClinicalTrials.gov identifier: NCT02123797) evaluating the thoroughness of lung cancer staging, receipt of stage-appropriate treatment, and survival between patients receiving care in the multidisciplinary clinic and those receiving usual serial care. Target enrollment was 150 patients on the multidisciplinary arm and 300 on the serial care arm. We frequency-matched patients by clinical stage, performance status, insurance type, race, and age. RESULTS: A total of 526 patients were enrolled: 178 on the multidisciplinary arm and 348 on the serial care arm. After adjusting for other factors, multidisciplinary patients had significantly higher odds (odds ratio [OR]: 2.3 [95% CI, 1.5 to 3.4]) of trimodality staging compared with serial care. Patients on the multidisciplinary arm also had higher odds of receiving invasive stage confirmation (OR: 2.0 [95% CI, 1.4 to 3.1]) and mediastinal stage confirmation (OR: 1.9 [95% CI, 1.3 to 2.8]). Additionally, patients receiving multidisciplinary care were significantly more likely to receive stage-appropriate treatment (OR: 1.8 [95% CI, 1.1 to 3.0]). We found no significant difference in overall or progression-free survival between study arms. CONCLUSION: The multidisciplinary clinic delivered significant improvements in evidence-based quality care on multiple levels. Even in the absence of a demonstrable survival benefit, these findings provide a strong rationale for recommending this model of care.

Lung Cancer Diagnosed Through Screening, Lung Nodule, and Neither Program: A Prospective Observational Study of the Detecting Early Lung Cancer (DELUGE) in the Mississippi Delta Cohort.

PURPOSE: Lung cancer screening saves lives, but implementation is challenging. We evaluated two approaches to early lung cancer detection-low-dose computed tomography screening (LDCT) and program-based management of incidentally detected lung nodules. METHODS: A prospective observational study enrolled patients in the early detection programs. For context, we compared them with patients managed in a Multidisciplinary Care Program. We compared clinical stage distribution, surgical resection rates, 3- and 5-year survival rates, and eligibility for LDCT screening of patients diagnosed with lung cancer. RESULTS: From 2015 to May 2021, 22,886 patients were enrolled: 5,659 in LDCT, 15,461 in Lung Nodule, and 1,766 in Multidisciplinary Care. Of 150, 698, and 1,010 patients diagnosed with lung cancer in the respective programs, 61%, 60%, and 44% were diagnosed at clinical stage I or II, whereas 19%, 20%, and 29% were stage IV (P = .0005); 47%, 42%, and 32% had curative-intent surgery (P < .0001); aggregate 3-year overall survival rates were 80% (95% CI, 73 to 88) versus 64% (60 to 68) versus 49% (46 to 53); 5-year overall survival rates were 76% (67 to 87) versus 60% (56 to 65) versus 44% (40 to 48), respectively. Only 46% of 1,858 patients with lung cancer would have been deemed eligible for LDCT by US Preventive Services Task Force (USPSTF) 2013 criteria, and 54% by 2021 criteria. Even if all eligible patients by USPSTF 2021 criteria had been enrolled into LDCT, the Nodule Program would have detected 20% of the stage I-II lung cancer in the entire cohort. CONCLUSION: LDCT and Lung Nodule Programs are complementary, expanding access to early lung cancer detection and curative treatment to different-risk populations. Implementing Lung Nodule Programs may alleviate emerging disparities in access to early lung cancer detection.

Interest in Cessation Treatment Among People Who Smoke in a Community-Based Multidisciplinary Thoracic Oncology Program.

INTRODUCTION: To evaluate the need for tobacco cessation services within a multidisciplinary clinic (MDC), we surveyed patients on their smoking status, interest in quitting, and willingness to participate in a clinic-based cessation program. We further evaluated the association between interest in cessation or willingness to participate in a cessation program and overall survival (OS). METHODS: From 2014 to 2019, all new patients with lung cancer in the MDC at Baptist Cancer Center (Memphis, TN) were administered a social history questionnaire to evaluate their demographic characteristics, smoking status, tobacco dependence, interest in quitting, and willingness to participate in a cessation program. We used chi-square tests and logistic regression to compare characteristics of those who would participate to those who would not or were unsure and Kaplan-Meier curves and Cox regression to evaluate the association between cessation interest or willingness to quit and OS. RESULTS: Of 641 total respondents, the average age was 69 years (range: 32-95), 47% were men, 64% white, 34% black, and 17% college graduates. A total of 90% had ever smoked: 34% currently and 25% quit within the past year. Among the current smokers, 60% were very interested in quitting and 37% would participate in a cessation program. Willingness to participate in a cessation program was associated with greater interest in quitting (p < 0.0001), better OS (p = 0.02), and reduced hazard of death (hazard ratio = 0.52, 95% confidence interval: 0.30-0.88), but no other characteristics. CONCLUSIONS: Patients with lung cancer in an MDC expressed considerable interest in tobacco cessation services; patients willing to participate in a clinic-based cessation program had improved survival.

Outcomes After Use of a Lymph Node Collection Kit for Lung Cancer Surgery: A Pragmatic, Population-Based, Multi-Institutional, Staggered Implementation Study.

INTRODUCTION: Suboptimal pathologic nodal staging prevails after curative-intent resection of lung cancer. We evaluated the impact of a lymph node specimen collection kit on lung cancer surgery outcomes in a prospective, population-based, staggered implementation study. METHODS: From January 1, 2014, to August 28, 2018, we implemented the kit in three homogeneous institutional cohorts involving 11 eligible hospitals from four contiguous hospital referral regions. Our primary outcome was pathologic nodal staging quality, defined by the following evidence-based measures: the number of lymph nodes or stations examined, proportions with poor-quality markers such as nonexamination of lymph nodes, and aggregate quality benchmarks including the National Comprehensive Cancer Network criteria. Additional outcomes included perioperative complications, health care utilization, and overall survival. RESULTS: Of 1492 participants, 56% had resection with the kit and 44% without. Pathologic nodal staging quality was significantly higher in the kit cases: 0.2% of kit cases versus 9.8% of nonkit cases had no lymph nodes examined; 3.2% versus 25.3% had no mediastinal lymph nodes; 75% versus 26% attained the National Comprehensive Cancer Network criteria (p < 0.0001 for all comparisons). Kit cases revealed no difference in perioperative complications or health care utilization except for significantly shorter duration of surgery, lower proportions with atelectasis, and slightly higher use of blood transfusion. Resection with the kit was associated with a lower hazard of death (crude, 0.78 [95% confidence interval: 0.61-0.99]; adjusted 0.85 [0.71-1.02]). CONCLUSIONS: Lung cancer surgery with a lymph node collection kit significantly improved pathologic nodal staging quality, with a trend toward survival improvement, without excessive perioperative morbidity or mortality.

Breastfeeding Rates and Programs in Europe: A Survey of 11 National Breastfeeding Committees and Representatives.

INTRODUCTION: Among the world's regions, the WHO European Region has the lowest rates of exclusive breastfeeding at the age of 6 months with approximately 25%. Low rates and early cessation of breastfeeding have important adverse health consequences for women, infants, and young children. Protecting, promoting, and supporting breastfeeding are a public health priority. OBJECTIVES: National breastfeeding data and monitoring systems among selected European countries and the WHO European Region are compared. Mechanisms for the support, protection, and promotion of breastfeeding are reviewed and successes and challenges in implementation of national programs are presented. METHODS: National representatives of national breastfeeding committees and initiatives in 11 European countries, including Belgium, Croatia, Denmark, Germany, Ireland, Italy, The Netherlands, Norway, Spain, Sweden, and Switzerland, participated in a standardized survey. Results are evaluated and compared in a narrative review. RESULTS: Variation exists in Europe on breastfeeding rates; methodology for data collection; and mechanisms for support, protection, and promotion of breastfeeding. Directly after birth, between 56% and 98% of infants in all countries were reported to receive any human milk, and at 6 months 38% to 71% and 13% to 39% of infants to be breastfed or exclusively breastfed, respectively. National plans addressing breastfeeding promotion, protection, and support exist in 6 of the 11 countries. CONCLUSIONS: National governments should commit to evidence-based breastfeeding monitoring and promotion activities, including financial and political support, to improve breastfeeding rates in the Europe. Renewed efforts for collaboration between countries in Europe, including a sustainable platform for information exchange, are needed.

Personal and perceived public mental-health stigma as predictors of help-seeking intentions in adolescents.

This study aimed to determine predictors of help-seeking intentions for symptoms of depression/anxiety and self-harm in adolescents. It focused on personal and perceived public stigma to gather data of value for the design of anti-stigma interventions. Participants (n = 722; 368 girls) were recruited from three cohorts of secondary school students in Ireland (mean ages: 1st = 12.9 years; 3rd = 14.9 years; 5th = 16.6 years). Hierarchical regression models indicated that perceived public stigma is a significant unique predictor of help-seeking intentions for depression [F(4, 717) = 13.4, p < .001] and self-harm [F(4, 717) = 13.5, p < .001]. This indicates that young people's beliefs about other people's stigma towards mental health problems was a stronger predictor of help-seeking intentions than their own stigma beliefs. These findings highlight the importance of looking separately at different types of stigma when investigating the role of stigma in predicting help-seeking intentions.

Pragmatic trial of a multidisciplinary lung cancer care model in a community healthcare setting: study design, implementation evaluation, and baseline clinical results.

BACKGROUND: Responsible for 25% of all US cancer deaths, lung cancer presents complex care-delivery challenges. Adoption of the highly recommended multidisciplinary care model suffers from a dearth of good quality evidence. Leading up to a prospective comparative-effectiveness study of multidisciplinary vs. serial care, we studied the implementation of a rigorously benchmarked multidisciplinary lung cancer clinic. METHODS: We used a mixed-methods approach to conduct a patient-centered, combined implementation and effectiveness study of a multidisciplinary model of lung cancer care. We established a co-located multidisciplinary clinic to study the implementation of this care-delivery model. We identified and engaged key stakeholders from the onset, used their input to develop the program structure, processes, performance benchmarks, and study endpoints (outcome-related process measures, patient- and caregiver-reported outcomes, survival). In this report, we describe the study design, process of implementation, comparative populations, and how they contrast with patients within the local and regional healthcare system. Trial Registration: ClinicalTrials.gov Identifier: NCT02123797. RESULTS: Implementation: the multidisciplinary clinic obtained an overall treatment concordance rate of 90% (target >85%). Satisfaction scores were high, with >95% of patients and caregivers rating themselves as being "very satisfied" with all aspects of care from the multidisciplinary team (patient/caregiver response rate >90%). The Reach of the multidisciplinary clinic included a higher proportion of minority patients, more women, and younger patients than the regional population. Comparative effectiveness: The comparative effectiveness trial conducted in the last phase of the study met the planned enrollment per statistical design, with 178 patients in the multidisciplinary arm and 348 in the serial care arm. The multidisciplinary cohort had older age and a higher percentage of racial minorities, with a higher proportion of stage IV patients in the serial care arm. CONCLUSIONS: This study demonstrates a comprehensive implementation of a multidisciplinary model of lung cancer care, which will advance the science behind implementing this much-advocated clinical care model.

Evolution in the Surgical Care of Patients With Non-Small Cell Lung Cancer in the Mid-South Quality of Surgical Resection Cohort.

Surgery is the most important curative treatment modality for patients with early-stage non-small cell lung cancer (NSCLC). We examined the pattern of surgical resection for NSCLC in a high incidence and mortality region of the United States over a 10-year period (2004-2013) in the context of a regional surgical quality improvement initiative. We abstracted patient-level data on all resections at 11 hospitals in 4 contiguous Dartmouth Hospital Referral Regions in North Mississippi, East Arkansas, and West Tennessee. Surgical quality measures focused on intraoperative practice, with emphasis on pathologic nodal staging. We used descriptive statistics and trend analyses to assess changes in practice over time. To measure the effect of an ongoing regional quality improvement intervention with a lymph node specimen collection kit, we used period effect analysis to compare trends between the preintervention and postintervention periods. Of 2566 patients, 18% had no preoperative biopsy, only 15% had a preoperative invasive staging test, and 11% underwent mediastinoscopy. The rate of resections with no mediastinal lymph nodes examined decreased from 48%-32% (P < 0.0001), whereas the rate of resections examining 3 or more mediastinal stations increased from 5%-49% (P < 0.0001). There was a significant period effect in the increase in the number of N1, mediastinal, and total lymph nodes examined (all P < 0.0001). A quality improvement intervention including a lymph node specimen collection kit shows early signs of having a significant positive effect on pathologic nodal examination in this population-based cohort. However, gaps in surgical quality remain.

Prognostic Value of National Comprehensive Cancer Network Lung Cancer Resection Quality Criteria.

BACKGROUND: The National Comprehensive Cancer Network (NCCN) surgical resection guidelines for non-small cell lung cancer recommend anatomic resection, negative margins, examination of hilar/intrapulmonary lymph nodes, and examination of three or more mediastinal nodal stations. We examined the survival impact of these criteria. METHODS: A population-based observational study was done using patient-level data from all curative-intent, non-small cell lung cancer resections from 2004 to 2013 at 11 institutions in four contiguous Dartmouth Hospital referral regions in three US states. We used an adjusted Cox proportional hazards model to assess the overall survival impact of attaining NCCN guidelines. RESULTS: Of 2,429 eligible resections, 91% were anatomic, 94% had negative margins, 51% sampled hilar nodes, and 26% examined three or more mediastinal nodal stations. Only 17% of resections met all four criteria; however, there was a significant increasing trend from 2% in 2004 to 39% in 2013 (p < 0.001). Compared with patients whose surgery missed one or more criteria, the hazard ratio for patients whose surgery met all four criteria was 0.71 (95% confidence interval: 0.59 to 0.86, p < 0.001). Margin status and the nodal staging criteria were most strongly linked with survival. CONCLUSIONS: Attainment of NCCN surgical quality guidelines was low, but improving, over the past decade in this cohort from a high lung cancer mortality region of the United States. The NCCN quality criteria, especially the nodal examination criteria, were strongly associated with survival. The quality of nodal examination should be a focus of quality improvement in non-small cell lung cancer care.

Novel retinoid ester in combination with salicylic acid for the treatment of acne.

BACKGROUND: Retinoids (RC), alpha-hydroxy acids (AHA), and salicylic acid (BHA) treat acne through differing mechanisms of action. It is theorized that optimal improvement can be achieved by combining the RC-induced normalization of cellular differentiation, AHA-induced exfoliation in hydrophilic areas, and BHA-induced exfoliation in lipophilic areas. AHA and RC have been combined in a bioengineered molecule (AHA retinoid conjugate, or AHA-RC) delivering both lactic acid (AHA) and RC in a manner reducing retinoid-associated irritation. OBJECTIVES: To evaluate efficacy and tolerability of a twice-daily, three-product skincare regimen using AHA-RC in combination with BHA for patients with acne. METHODS: A total of 27 women (age range 20-58 years, mean 37.81 ± 10.04 years) with mild-to-moderate acne used a 3-product regimen consisting of a twice-daily cleanser and topical serum (0.1% AHA-RC, 2% salicylic acid, and 10.4% l-lactic acid), with broad-spectrum SPF 50+ sunscreen as needed, over an 8-week period. Counts were made at baseline, week 4, and week 8 of total inflammatory (papules, pustules) and noninflammatory (open comedones, closed comedones) lesions. Dryness, stinging, and other secondary endpoints were rated on a 0-5 scale. RESULTS: Statistically significant reduction in inflammatory and noninflammatory lesion counts (P = 0.006 and P = 0.015, respectively) was noted at 4 weeks. Improvement continued into week 8 with highly significant (P < 0.001) reductions in both lesion counts. CONCLUSIONS: The topical combination of lactic acid, SA, and AHA-RC produced acne improvement after 4 weeks with continuing cumulative improvement at 8 weeks. AHA-RC represents a new molecule combining several mechanisms of action to achieve acne improvement.

The Tolerability and Efficacy of a Three-product Anti-aging Treatment Regimen in Subjects with Moderate-to-severe Photodamage.

Retinoids and alpha hydroxy acids differ in mechanism of action for treatment of photodamage, but concurrent use may produce a synergistic effect by combining retinoid-induced normalization of cellular differentiation with alpha hydroxy acid-induced exfoliation (in hydrophilic areas) and enhanced dermal and epidermal hydration. A recent bioengineered molecule, ethyl lactyl retinoate (alpha hydroxy acid retinoid conjugate), is the first to deliver alpha hydroxy acids and retinoids together in a hydrolysis-based time-released fashion. This could improve efficacy while minimizing irritation commonly associated with retinoid use. An eight-week clinical study was conducted to examine the efficacy and tolerability of this formulation; 25 women aged 54.1 ±8.9 years (mean ± SD) with moderate-to-severe photodamage (as determined by physician investigators using the Glogau Wrinkle Scale) employed a twice-daily regimen of cleanser (7.8% 1-lactic acid, 2% salicylic acid) and anti-aging serum (0.1% alpha hydroxy acids-retinoids, 6.5% 1-lactic acid) with concurrent use of sun protection factor 50+ sunscreen as needed. Longitudinal analysis of study data revealed statistically significant improvement in photodamage, dryness/flaking, dyschromia, and global appearance at eight weeks. All study products were well-tolerated throughout. Investigators concluded that the alpha hydroxy acid retinoid conjugate is a safe and effective topical therapy for moderate-to-severe photodamage, warranting further study, (clinicaltrials.gov, NCT02422836, https://clinicaltrials.gov/ct2/show/NCT02422836?term=NCT02422836).

'One-stop shop': lung cancer patients' and caregivers' perceptions of multidisciplinary care in a community healthcare setting.

BACKGROUND: Multidisciplinary care is rarely practiced in community healthcare settings where the majority of patients receive lung cancer care in the US. We sought direct input from patients and their informal caregivers on their experience of lung cancer care delivery. METHODS: We conducted focus groups of patient and caregiver dyads. Patients had received care for lung cancer in or out of a multidisciplinary thoracic oncology clinic coordinated by a nurse navigator. Focus groups were audiotaped, transcribed, and analyzed using Creswell's 7-step process. Recurring overlapping themes were developed using constant comparative methods within the Grounded Theory framework. RESULTS: A total of 46 participants were interviewed in focus groups of 5 patient-caregiver dyads. Overlapping themes were a perception that multidisciplinary care improved physician collaboration, patient-physician communication, and patient convenience, while reducing redundancy in testing. Improved coordination decreased confusion, stress, and anxiety. Negative experience of serial care included poor communication among physicians, insensitive communication about illness, delays in diagnosis and treatment, misdiagnosis, and mistreatment. Physician-to-physician communication and patient education were suggested areas for improvement in the multidisciplinary model. CONCLUSIONS: Multidisciplinary care was perceived as more patient-centered, effective, safe, and efficient than standard serial care. It was also believed to improve the timeliness of care and equitable access to high quality care. Additional studies to compare these perspectives to those of other key stakeholders, including clinicians, hospital administrators and representatives of third party payers, will facilitate better understanding of the role of multidisciplinary care programs in lung cancer care delivery.

Preoperative Evaluation of Lung Cancer in a Community Health Care Setting.

BACKGROUND: We examined the presurgical evaluation of suspected lung cancer patients in a community-based health care system to establish current benchmarks of care that will lay the groundwork for an evidence-based quality improvement project. METHODS: We retrospectively reviewed clinical records of all recipients of lung resection at two institutions, and classified all lung cancer relevant procedures into five "nodal points": lesion detection, diagnostic biopsy, radiologic staging, invasive staging, and treatment. We analyzed the frequency of passage through each nodal point, the time intervals between nodal points, and the use of staging modalities. RESULTS: Of 614 eligible patients, 92% had lung cancer, 5% had a non-lung primary tumor, 3% had a benign lesion. Six percent received preoperative therapy; 39% of resections were minimally invasive. Ninety-eight percent of patients had a preoperative computed tomography (CT) scan, 27% had no preoperative diagnostic procedure, 22% had no preoperative positron emission tomography (PET)/CT scans, and 88% had no invasive preoperative staging test. Only 10% had trimodality staging with CT, PET/CT, and invasive staging. Twenty-one percent of patients who had an invasive staging test had mediastinal nodal metastasis at resection. The median duration (interquartile range) from initial lesion identification to resection was 84 days (43 to 189) days; from lesion identification to diagnostic biopsy, 28 days (7 to 96); and from diagnostic biopsy to surgery, 40 days (26 to 69). CONCLUSIONS: There is opportunity for improvement in the thoroughness, accuracy, and timeliness of preoperative evaluation of suspected lung cancer patients in this community cohort. Better coordination of care may significantly improve these benchmarks.

Audit of lymphadenectomy in lung cancer resections using a specimen collection kit and checklist.

BACKGROUND: Audits of operative summaries and pathology reports reveal wide discordance in identifying the extent of lymphadenectomy performed (the communication gap). We tested the ability of a prelabeled lymph node specimen collection kit and checklist to narrow the communication gap between operating surgeons, pathologists, and auditors of surgeons' operation notes. METHODS: We conducted a prospective single cohort study of lung cancer resections performed with a lymph node collection kit from November 2010 to January 2013. We used the kappa statistic to compare surgeon claims on a checklist of lymph node stations harvested intraoperatively with pathology reports and an independent audit of surgeons' operative summaries. Lymph node collection procedures were classified into four groups based on the anatomic origin of resected lymph nodes: mediastinal lymph node dissection, systematic sampling, random sampling, and no sampling. RESULTS: From the pathology reports, 73% of 160 resections had a mediastinal lymph node dissection or systematic sampling procedure, 27% had random sampling. The concordance with surgeon claims was 80% (kappa statistic 0.69, 95% confidence interval: 0.60 to 0.79). Concordance between independent audits of the operation notes and either the pathology report (kappa 0.14, 95% confidence interval: 0.04 to 0.23) or surgeon claims (kappa 0.09, 95% confidence interval: 0.03 to 0.22) was poor. CONCLUSIONS: A prelabeled specimen collection kit and checklist significantly narrowed the communication gap between surgeons and pathologists in identifying the extent of lymphadenectomy. Audit of surgeons' operation notes did not accurately reflect the procedure performed, bringing its value for quality improvement work into question.

Size and histologic characteristics of lymph node material retrieved from tissue discarded after routine pathologic examination of lung cancer resection specimens.

Redissection of discarded lung resection specimens after routine pathology examination reveals missed lymph node metastasis. We sought to determine if size can be used to grossly select lymph nodes for microscopic examination. This is a prospective cohort study of lymph nodes retrieved from discarded lung resection specimens. The association between size and histologic characteristics of retrieved material was compared by the Wilcoxon-Mann-Whitney test. We retrieved 1094 grossly 'lymph node-like" tissue from 112 remnant lung resection specimens, of which 345 (32%) proved not to be lymph nodes and 71 (9%) of 749 lymph nodes had metastasis. Metastasis was present in discarded nodes in 26 (23%) of 112 patients. The non-lymph node tissue was significantly smaller than lymph nodes (P < .0001); lymph nodes with metastases were significantly larger than those without metastases (P < .0001). However, there was significant size overlap between the 3 types of grossly lymph node-like tissue. Thirty-two percent of nodes with metastasis were less than 1 cm; 15% of patients had at least 1 lymph node less than 1 cm with metastasis. The size difference between lymph nodes with and without metastasis is clinically unhelpful because of broad overlap. Size is insufficiently discriminatory and cannot be relied on to select materials for histologic examination. A third of grossly retrieved material was non-lymph node tissue. This probably occurs during routine pathologic examination and likely contributes to the low N1 lymph node count.

A transition pilot program for adolescents with sickle cell disease.

INTRODUCTION: Transition from pediatric to adult care is challenging for adolescents with chronic illnesses, including those with sickle cell disease (SCD). We describe a pilot program created to facilitate transition from pediatric to adult care by helping adolescents with SCD identify an adult medical home. METHODS: We investigated the feasibility of this program by evaluation of overall participation, satisfaction, and acceptance. A secondary objective was to compare the proportion of adolescents who fulfilled a first appointment with an adult hematologist among participants and nonparticipants. RESULTS: During the first 18 months of the program, 83 adolescents were invited and 34 (41%) agreed to participate; 25 (74%) completed their first visit within 3 months after leaving the pediatric program, compared with 16 of 49 (33%) of nonparticipants (p = .0002). Overall, 41 of 83 adolescents (49%) completed an appointment with an adult SCD program, regardless of program participation, in contrast with 11 of 75 adolescents (15%) who did so during the 18 months before the program was created (p < .0001). DISCUSSION: This transition pilot program was feasible, and most adolescent participants with SCD established an adult medical home.
