Pilot Study Demonstrating the Value of Interdisciplinary Education on the Integration of Radiation Therapy in Lung Cancer Management.

ABSTRACT: This study aimed to understand baseline knowledge of basic principles of radiation therapy for lung cancer among medical oncology, thoracic surgery, and pulmonology trainees and practicing physicians and also assess whether a didactic lecture will improve objective knowledge and perceived comfort level in making appropriate referrals to radiation oncology (RO). Radiation oncologists at 8 academic institutions offered a presentation covering indications, logistics, efficacy, and toxicity of thoracic radiation. Participants completed a survey to assess their prior exposures to RO and perceived value of the lecture, and objective knowledge gained based on pre/post-lecture questions. Among 121 attendees, 76 completed the pre-test, and 25 the post-test (response rates 62.8% and 20.7%, respectively). Fifty-seven (75.0%) had never previously experienced a RO didactic about lung cancer, 62 (81.6%) had never seen a linear accelerator, and 65 (85.5%) had never rotated in a RO department. The mean pre-test score was 53.5% (SD 17.6%), with a trend (p = 0.066) towards thoracic surgeons (61.5%) performing better than medical oncologists (55.5%) or pulmonologists (48.3%). Level of training (p = 0.130), and prior RO exposures (p = 0.240), did not significantly impact pre-test scores. The mean post-test score of 75.1% (SD 3.6%) was significantly higher than mean pre-test score (p < 0.001). After the lecture, 25 participants (100%) felt more knowledgeable about RO, and 24 (96%) felt more comfortable making appropriate referrals to RO. A didactic lecture about RO for trainees and physicians who treat lung cancer at 8 academic institutions was feasible, filled a gap in exposure, and improved knowledge.

Project description:BackgroundStereotactic body radiation therapy (SBRT) is an effective treatment modality for non-small cell lung cancer (NSCLC); however, there are concerns regarding potential toxicity for centrally located tumors.MethodsThis retrospective study considered patients with SBRT for central lung NSCLC (defined as a tumor within 2 cm of any mediastinal critical structure). The institutional protocol was that patients with central tumors received SBRT less frequently than daily-generally once or twice weekly.ResultsA total of 115 patients with 148 lesions were treated with SBRT to a median 45 [5-60] Gy in 4 [1-5] fractions over a median 5.3 [0-18] days. Many patients treated with this method presented with advanced disease: 58 treatments involved nodal targets, and 42 had stage 3 disease. 52% of patients had chronic obstructive pulmonary disease (COPD), and only 49% had a biopsy, often due to concerns regarding other medical comorbidities. Rates of prior chemotherapy, thoracic surgery, and thoracic radiotherapy were 32%, 21%, and 49%, respectively. Via the Kaplan-Meier method, 2-year overall survival was 65%, and 2-year local control was 77%. Two-year local-progression free survival was 53%, and 2-year progression-survival was 48%. Treatments for stage 3 disease had an impressive 82% 2-year local control that was comparable to early stage treatments. Patients with stage 3 disease had a 2-year overall survival of 59%, which trended towards decreased overall survival compared to early stage patients. There were 13 grade 1 (9%) and 14 grade 2 (9%) toxicities. There were no reported grade ≥3 acute or late toxicities and only 3 cases of pneumonitis.ConclusionsOur series demonstrates encouraging local control with low rates of toxicity for central lung SBRT, including many stage 3 patients. This may be the result of the relatively large inter-fraction interval. This interval may allow for greater tumor effects (such as reoxygenation) and improved tolerance from normal tissues.

Project description:The value proposition for biosimilars can be characterized as a concept that moves beyond the argument of cost reduction relative to the innovator biologic drug and into a framework that incorporates the diverse needs of key healthcare stakeholders during the transition from clinical development to commercialization in the marketplace.To identify factors that facilitate and inhibit the development, commercialization, and adoption of biosimilars, and to recommend modifications in program design that are likely to support the demonstration of the value of biosimilars for payers, providers, and patients.The primary data sources for this article include surveys conducted by Boston Healthcare Associates with payers and clinicians in the United States and the European Union 5 markets and blinded international protocol feasibility assessments completed by Worldwide Clinical Trials. Survey methodology used either convenience or purposeful sampling as appropriate, with participants extracted from diverse audiences, representative of those who generate or evaluate clinical data shaping the economic exchange and preferential status influencing physician adoption and patient access to biosimilars. Patient characteristics and psychosocial issues influencing patients' perception of small-molecule generics were extracted from the available literature to inform exploratory hypotheses, given the relative absence of such information for biosimilars.This article reviews the current evidence and summarizes results of surveys conducted with payers, providers, and drug investigation sites in the United States. Based on a review of published literature, as well as these survey results, conflicting and convergent demands exist for gathering data related to biosimilars. The motivations and data needs for these new agents are diverse, requiring adjudication of regulatory, economic, and clinical incentives beginning at program inception and extending through commercialization of the final biosimilar agent.The development and commercialization of biosimilars represent an international activity that can encounter unanticipated challenges, as well as opportunities to achieve clinical and commercial success. Evolving regulatory guidance mapped in relation to payer, physician, and patient sentiments may inform the biosimilar development program designs, implementation, and positioning of the new drug.
