ABSTRACT

A recent interpretation of the Stark Law limits cancer practices from delivering drugs to their patients by mail or courier-a perverse interpretation of a law meant to curb physician self-referrals and one that has led to patient harm.

ABSTRACT

PURPOSE: Oral mucositis (OM) remains a common, debilitating toxicity of radiation therapy (RT) for head and neck cancer. The goal of this phase IIb, multi-institutional, randomized, double-blind trial was to compare the efficacy and safety of GC4419, a superoxide dismutase mimetic, with placebo to reduce the duration, incidence, and severity of severe OM (SOM). PATIENTS AND METHODS: A total of 223 patients (from 44 institutions) with locally advanced oral cavity or oropharynx cancer planned to be treated with definitive or postoperative intensity-modulated RT (IMRT; 60 to 72 Gy [≥ 50 Gy to two or more oral sites]) plus cisplatin (weekly or every 3 weeks) were randomly assigned to receive 30 mg (n = 73) or 90 mg (n = 76) of GC4419 or to receive placebo (n = 74) by 60-minute intravenous administration before each IMRT fraction. WHO grade of OM was assessed biweekly during IMRT and then weekly for up to 8 weeks after IMRT. The primary endpoint was duration of SOM tested for each active dose level versus placebo (intent-to-treat population, two-sided α of .05). The National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.03, was used for adverse event grading. RESULTS: Baseline patient and tumor characteristics as well as treatment delivery were balanced. With 90 mg GC4419 versus placebo, SOM duration was significantly reduced (P = .024; median, 1.5 v 19 days). SOM incidence (43% v 65%; P = .009) and severity (grade 4 incidence, 16% v 30%; P = .045) also were improved. Intermediate improvements were seen with the 30-mg dose. Safety was comparable across arms, with no significant GC4419-specific toxicity nor increase of known toxicities of IMRT plus cisplatin. The 2-year follow-up for tumor outcomes is ongoing. CONCLUSION: GC4419 at a dose of 90 mg produced a significant, clinically meaningful reduction of SOM duration, incidence, and severity with acceptable safety. A phase III trial (ROMAN; ClinicalTrials.gov identifier: NCT03689712) has begun.

ABSTRACT

Effective communication is a requirement in the teamwork necessary for improved coordination to deliver patient-centered, value-based cancer care. Communication is particularly important when care providers are geographically distributed or work across organizations. We review organizational and teams research on communication to highlight psychological safety as a key determinant of high-quality communication within teams. We first present the concept of psychological safety, findings about its communication effects for teamwork, and factors that affect it. We focus on five factors applicable to cancer care delivery: familiarity, clinical hierarchy-related status differences, geographic dispersion, boundary spanning, and leader behavior. To illustrate how these factors facilitate or hinder psychologically safe communication and teamwork in cancer care, we review the case of a patient as she experiences the treatment-planning process for early-stage breast cancer in a community setting. Our analysis is summarized in a key principle: Teamwork in cancer care requires high-quality communication, which depends on psychological safety for all team members, clinicians and patients alike. We conclude with a discussion of the implications of psychological safety in clinical care and suggestions for future research.

ABSTRACT

Chromosomal instability (CIN) is a hallmark of cancer that contributes to tumour heterogeneity and other malignant properties. Aberrant centromere and kinetochore function causes CIN through chromosome missegregation, leading to aneuploidy, rearrangements and micronucleus formation. Here we develop a Centromere and kinetochore gene Expression Score (CES) signature that quantifies the centromere and kinetochore gene misexpression in cancers. High CES values correlate with increased levels of genomic instability and several specific adverse tumour properties, and prognosticate poor patient survival for breast and lung cancers, especially early-stage tumours. They also signify high levels of genomic instability that sensitize cancer cells to additional genotoxicity. Thus, the CES signature forecasts patient response to adjuvant chemotherapy or radiotherapy. Our results demonstrate the prognostic and predictive power of the CES, suggest a role for centromere misregulation in cancer progression, and support the idea that tumours with extremely high CIN are less tolerant to specific genotoxic therapies.

ABSTRACT

Stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS) are advanced radiotherapy delivery techniques that allow for the delivery of high-dose per fraction radiation. Advances in imaging technology and intensity modulation have allowed SRS and SBRT to be used for the treatment of tumors in close proximity to the spinal cord and cauda equina, in particular spinal metastases. While the initial treatment of spinal metastases is often conventional palliative radiotherapy, treatment failure is not uncommon, and conventional re-irradiation may not be feasible due to spinal cord tolerance. SBRT and SRS have emerged as important techniques for the treatment of spinal metastases in the proximity of previously irradiated spinal cord. Here we review the current data on the use of SBRT and SRS spinal re-irradiation, and future directions for these important treatment modalities.

ABSTRACT

Substantial controversy remains regarding the optimal adjuvant treatment for patients with resectable pancreatic adenocarcinoma. Despite improvements in radiation techniques, systemic therapies, and incorporation of targeted agents, the 5-year survival rates for early stage patients remains less than 25% and the optimal adjuvant treatment approach remains unclear. Here we summarize the data presented at the 2012 American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium regarding controversial issues surrounding the role, timing, and selection of patients for adjuvant chemoradiation strategies following curative resection for pancreatic adenocarcinoma. (Abstracts #301, #333, and #206).

ABSTRACT

BACKGROUND: Limited data evaluate intensity-modulated radiotherapy (IMRT) for cancers of the hypopharynx and larynx. We report clinical outcomes and failure patterns for these patients. METHODS: Between September 2001 and December 2007, 42 patients with squamous cell carcinoma (SCC) of the hypopharynx (n = 23) and larynx (n = 19) underwent IMRT, 11 postoperatively and 31 definitively. Thirty-six received systemic therapy. Median follow-up was 30 months among surviving patients. RESULTS: Three local failures occurred within the high-dose region and 3 occurred in regional nodes. Seven patients developed distant metastasis as the initial failure. Three-year actuarial estimates of locoregional control, freedom from distant metastasis, and overall survival rates were, respectively, 80%, 72%, and 46%. CONCLUSIONS: IMRT provides good locoregional control for SCC of the hypopharynx and larynx compared with historical controls. Locoregional relapses occurred in the high-dose volumes, suggesting adequate target volume delineation. Hypopharyngeal tumors, which fare worse than laryngeal tumors, warrant investigation of more aggressive treatment.

ABSTRACT

The complexity of health care delivery within the United States continues to escalate in an exponential fashion driven by an explosion of medical technology, an ever-expanding research enterprise, and a growing emphasis on evidence-based practices. The delivery of care occurs on a continuum that spans across multiple disciplines, now requiring complex coordination of care through the use of novel clinical teams. The use of teams permeates the health care industry and has done so for many years, but confusion about the structure and role of teams in many organizations contributes to limited effectiveness and suboptimal outcomes. Teams are an essential component of graduate medical education training programs. The health care industry's relative lack of focus regarding the fundamentals of teamwork theory has contributed to ineffective team leadership at the physician level. As a follow-up to our earlier manuscripts on teamwork, this article clarifies a model of teamwork and discusses its application to high-performance teams in health care organizations. Emphasized in this discussion is the role played by the physician leader in ensuring team effectiveness. By educating health care professionals on the fundamentals of high-performance teamwork, we hope to stimulate the development of future physician leaders who use proven teamwork principles to achieve the goals of trainee education and excellent patient care.

ABSTRACT

INTRODUCTION: The current standard of care for good performance status patients with locally advanced non-small cell lung carcinoma is concurrent chemoradiation, although a clearly superior regimen has not been identified. Docetaxel has been shown to possess good single-agent activity against non-small cell lung cancer (NSCLC) and radiosensitizing properties, both alone and synergistically with carboplatin. We undertook this phase II study to determine the safety and efficacy of weekly docetaxel-carboplatin and concurrent radiation therapy followed by docetaxel-carboplatin consolidation for the treatment of locally advanced NSCLC. METHODS: Sixty-seven patients having previously untreated stage IIIA or IIIB unresectable NSCLC were enrolled, with 61 patients evaluated for endpoints. Docetaxel 20 mg/m IV infusion over 30 minutes followed by carboplatin area under the curve = 2 over 30 minutes was administered weekly during concurrent thoracic radiotherapy. After 3 week rest, consolidation docetaxel 75 mg/m(2) IV infusion over 60 minutes and carboplatin area under the curve = 6 over 30 minutes was administered every 3 weeks for two cycles. Concurrent thoracic radiation consisted of 45 Gy (1.8 Gy fractions 5 d/wk for first 5 weeks) followed by 18 Gy boost (2.0 Gy fractions 5 d/wk for 2 weeks) for a total dose of 63 Gy. RESULTS: One and 2 years overall survival rates were 45 and 20%, respectively. Progression free survival at 1 year was 27%. Median survival time was 12 months. Median time to progression was 8 months. The primary hematologic toxicity was leukopenia. The primary nonhematologic toxicity was esophagitis. CONCLUSION: The administered regimen of weekly docetaxel-carboplatin and concurrent radiation therapy followed by docetaxel-carboplatin consolidation has acceptable toxicity profile. However, the overall survivals at 1 and 2 years are somewhat disappointing.

ABSTRACT

PURPOSE: The optimal dose of gemcitabine that can be used with concurrent radiation therapy for locally advanced non-small cell lung cancer has not been well defined. This trial addresses this question in an alternating sequence "ping-pong" design trial to find the maximum tolerated dose (MTD) for gemcitabine/carboplatin (Sequence A) or gemcitabine/paclitaxel (Sequence B) and thoracic radiation therapy followed by adjuvant gemcitabine/carboplatin chemotherapy. PATIENTS AND METHODS: Thirty-five patients with histologically confirmed Stage IIIA/B non-small cell lung cancer were entered into two separate sequences, each with multiple cohorts. A dose level was considered acceptable if, of the first six eligible patients on each cohort, fewer than three experienced dose limiting toxicities. RESULTS: Sequence B of this 2 sequence "ping-pong" trial closed early due to toxicity in cohort 2 (gemcitabine 300 mg/m/wk and paclitaxel 30 mg/m/wk). On Sequence A, the MTD was the cohort 5 dose: gemcitabine 450 mg/m/wk and carboplatin 2 area under curve (AUC) concurrently with thoracic radiation. Cohort 7 (gemcitabine 600 mg/m/wk and carboplatin 2 AUC) showed 4 dose limiting toxicities: 2 grade 3 esophagitis; one grade 3 febrile neutropenia; and one grade 4 neutropenia. CONCLUSION: Concurrent gemcitabine/paclitaxel chemoradiation regimen followed by adjuvant gemcitabine/carboplatin produced excessive toxicity at the lowest tested dose combination and was not suitable for further study in this trial. Meanwhile, the MTD of concurrent gemcitabine/carboplatin chemoradiation was determined to be gemcitabine 450 mg/m and carboplatin AUC-2. This combination was found to be tolerable. Although not a primary end point, survival results are summarized as well.

ABSTRACT

The scope of patient management increasingly crosses the defined lines of multiple medical specialties and services to meet patient needs. Concurrently, many hospitals and health-care systems have adapted new multidisciplinary team structures that provide patient-centric care as opposed to the more traditional discipline-centered delivery of care. As health care continues to evolve, the use of teams becomes even more critical in allowing interdependence between multiple disciplines to provide excellent care delivery and ongoing patient management. The use of teams permeates the health-care industry (and has done so for many years), but confusion about the structure, role, and use of teams contributes to limited effectiveness. The health-care industry's underuse of the fundamentals of corporate teamwork has, in part, created ineffective team leadership at the physician level. As the first in a series of documents on teamwork, this article is intended to introduce the reader to the rudiments of team theory and to present an introduction to a model of teamwork. The role of current and future physician leaders in ensuring team effectiveness is emphasized in this discussion. By educating health-care professionals on the foundations of high-performance teamwork, we hope to accomplish two main goals. The first goal is to help create a common and systematic taxonomy that physician leaders and institutional management can agree on and refer to concerning the development of high-performance health-care teams. The second goal is to stimulate the development of future physician leaders who use proven teamwork principles as a powerful modality to achieve efficient and optimal patient care. Most importantly, we wish to emphasize that health care, both philosophically and practically, is delivered best through high-performance teams. For such teams to perform properly, the organizational environment must support the team concept tangibly. In concert, we believe the best manner in which to cultivate knowledge and performance of the health-care organizational mission and goals is by using such teams.

ABSTRACT

In the demanding and unpredictable environment of the health care industry, hospitals and health systems continue to search for ways to improve the efficiency and quality of care provision and, thus, thrive. Service line organization in health care, a concept that was popularized in the past, has recently experienced a resurgence, spanning the gamut from small community hospitals to large academic medical centers. The modern service line has transformed into an organizational tool that provides hospitals and health systems with a novel approach to achieve the goals of efficient and effective care. Physician leaders can play an integral role in the management of service lines, using a combination of management skills and clinical expertise to provide the oversight and direction necessary for assuring excellence in clinical care and value in its delivery. This article presents an overview of service line structure, implementation, implications, and the role of the physician-leader.

ABSTRACT

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for their anti-inflammatory effects and have been shown to have chemopreventive effects as well. NSAIDs inhibit cyclooxygenase (COX) activity to exert their anti-inflammatory effects, but it is not clear whether their antitumorigenic ability is through COX inhibition. Using subtractive hybridization, we previously identified a novel member of the transforming growth factor-beta superfamily that has antitumorigenic activity from indomethacin-treated HCT-116 human colorectal cancer cells. On further investigation of this library, we now report the identification of a new cDNA corresponding to the thymosin beta-4 gene. Thymosin beta-4 is a small peptide that is known for its actin-sequestering function, and it is associated with the induction of angiogenesis, accelerated wound healing, and metastatic potential of tumor cells. However, only selective NSAIDs induce thymosin beta-4 expression in a time- and concentration-dependent manner. For example, indomethacin and SC-560 [5-(4-chlorophenyl)-1-(4-methoxyphenyl)-3-(trifluoromethyl)-1H-pyrazole] induce thymosin beta-4 expression whereas sulindac sulfide does not. We show that selective NSAIDs induce actin cytoskeletal reorganization, a precursory step to many dynamic processes regulating growth and motility including tumorigenesis. This is the first report to link thymosin beta-4 induction with NSAIDs. These data suggest that NSAIDs alter the expression of a diverse number of genes and provide new insights into the chemopreventive and biological activity of these drugs.
