American Society of Clinical Oncology Policy Statement on Clinical Pathways in Oncology.

The use of clinical pathways in oncology care is increasingly important to patients and oncology providers as a tool for enhancing both quality and value. However, with increasing adoption of pathways into oncology practice, concerns have been raised by ASCO members and other stakeholders. These include the process being used for pathway development, the administrative burdens on oncology practices of reporting on pathway adherence, and understanding the true impact of pathway use on patient health outcomes. To address these concerns, ASCO's Board of Directors established a Task Force on Clinical Pathways, charged with articulating a set of recommendations to improve the development of oncology pathways and processes, allowing the demonstration of pathway concordance in a manner that promotes evidence-based, high-value care respecting input from patients, payers, and providers. These recommendations have been approved and adopted by ASCO's Board of Directors on August 12, 2015, and are presented herein.

Systemic therapy in men with metastatic castration-resistant prostate cancer:American Society of Clinical Oncology and Cancer Care Ontario clinical practice guideline.

PURPOSE: To provide treatment recommendations for men with metastatic castration-resistant prostate cancer (CRPC). METHODS: The American Society of Clinical Oncology and Cancer Care Ontario convened an expert panel to develop evidence-based recommendations informed by a systematic review of the literature. RESULTS: When added to androgen deprivation, therapies demonstrating improved survival, improved quality of life (QOL), and favorable benefit-harm balance include abiraterone acetate/prednisone, enzalutamide, and radium-223 ((223)Ra; for men with predominantly bone metastases). Improved survival and QOL with moderate toxicity risk are associated with docetaxel/prednisone. For asymptomatic/minimally symptomatic men, improved survival with unclear QOL impact and low toxicity are associated with sipuleucel-T. For men who previously received docetaxel, improved survival, unclear QOL impact, and moderate to high toxicity risk are associated with cabazitaxel/prednisone. Modest QOL benefit (without survival benefit) and high toxicity risk are associated with mitoxantrone/prednisone after docetaxel. No benefit and excess toxicity are observed with bevacizumab, estramustine, and sunitinib. RECOMMENDATIONS: Continue androgen deprivation (pharmaceutical or surgical) indefinitely. Abiraterone acetate/prednisone, enzalutamide, or (223)Ra should be offered; docetaxel/prednisone should also be offered, accompanied by discussion of toxicity risk. Sipuleucel-T may be offered to asymptomatic/minimally symptomatic men. For men who have experienced progression with docetaxel, cabazitaxel may be offered, accompanied by discussion of toxicity risk. Mitoxantrone may be offered, accompanied by discussion of limited clinical benefit and toxicity risk. Ketoconazole or antiandrogens (eg, bicalutamide, flutamide, nilutamide) may be offered, accompanied by discussion of limited known clinical benefit. Bevacizumab, estramustine, and sunitinib should not be offered. There is insufficient evidence to evaluate optimal sequences or combinations of therapies. Palliative care should be offered to all patients.

Assessment of risk evaluation and mitigation strategies in oncology: summary of the oncology risk evaluation and mitigation strategies workshop.

To address oncology community stakeholder concerns regarding implementation of the Risk Evaluation and Mitigation Strategies (REMS) program, ASCO sponsored a workshop to gather REMS experiences from representatives of professional societies, patient organizations, pharmaceutical companies, and the US Food and Drug Administration (FDA). Stakeholder presentations and topical panel discussions addressed REMS program development, implementation processes, and practice experiences, as well as oncology drug safety processes. A draft REMS decision tool prepared by the ASCO REMS Steering Committee was presented for group discussion with facilitated, goal-oriented feedback. THE WORKSHOP IDENTIFIED SEVERAL UNINTENDED CONSEQUENCES RESULTING FROM CURRENT ONCOLOGY REMS: (1) the release of personal health information to drug sponsors as a condition for gaining access to a needed drug; (2) risk information that is not tailored-and therefore not accessible-to all literacy levels; (3) exclusive focus on drug risk, thereby affecting patient-provider treatment discussion; (4) REMS elements that do not consider existing, widely practiced oncology safety standards, professional training, and experience; and (5) administrative burdens that divert the health care team from direct patient care activities and, in some cases, could limit patient access to important therapies. Increased provider and professional society participation should form the basis of ongoing and future REMS standardization discussions with the FDA to work toward overall improvement of risk communication.

A randomized, open-label pilot study comparing desirudin and argatroban in patients with suspected heparin-induced thrombocytopenia with or without thrombosis: PREVENT-HIT Study.

Because of an extreme risk for thromboemboli, patients with suspected heparin-induced thrombocytopenia (HIT) require immediate initiation of an alternative anticoagulant. The only therapies approved by the Food and Drug Administration require intravenous infusion of expensive direct thrombin inhibitors. This prospective, randomized, open-label, exploratory study compared the clinical and economic utility of subcutaneous desirudin vs argatroban, the most frequently used agent for suspected or immunologically confirmed HIT, with or without thrombosis. Sixteen patients were randomized to treatment with fixed-dose desirudin (15 or 30 mg) every 12 hours or activated partial thromboplastin time-adjusted argatroban by intravenous infusion. Arm A included 8 patients naive to direct thrombin inhibitor therapy, whereas Arm B included 8 patients on argatroban for at least 24 hours before randomization. The primary efficacy measure was the composite of new or worsening thrombosis (objectively documented), amputation, or death. Other end points included major and minor bleeding while on drug therapy, time to platelet count recovery, and pharmacoeconomics. No amputations or deaths occurred. One patient randomized to argatroban had worsening of an existing thrombosis. Major bleeding occurred in 2 patients on argatroban and in none during desirudin treatment. There was 1 minor bleed in each treatment group. The average medication cost per course of treatment was $1688 for desirudin and $8250 for argatroban. Desirudin warrants further study as a potentially cost-effective alternative to argatroban in patients with suspected HIT.

Rationale and design of the PREVENT-HIT study: a randomized, open-label pilot study to compare desirudin and argatroban in patients with suspected heparin-induced thrombocytopenia with or without thrombosis.

BACKGROUND: Desirudin, a bivalent direct thrombin inhibitor (DTI), is approved by the US Food and Drug Administration for the prevention of deep vein thrombosis, which may lead to pulmonary embolism, in patients undergoing elective hip replacement surgery. It became available in the United States in March 2010. OBJECTIVE: The goal of the present article was to provide an overview of the rationale and design of the PREVENT-HIT study, a randomized, prospective, open-label, active drug-controlled, exploratory trial comparing the clinical and economic utility of desirudin versus argatroban in patients with suspected heparin-induced thrombocytopenia (HIT), with or without thrombosis. SUMMARY: The PREVENT-HIT study was designed to enroll approximately 120 patients from 20 to 25 US centers. All eligible patients were required to be aged >or=18 years. Patients with suspected HIT with or without thrombosis were divided into 2 treatment arms and randomized to receive treatment with desirudin or argatroban in a 1:1 ratio using a block randomization method. Arm A comprised patients who were naive to DTI therapy; arm B included patients whose condition was previously stabilized with intravenous argatroban. Desirudin was administered as a fixed-dose injection (15 or 30 mg SC q12h in patients without or with thrombosis, respectively). Argatroban was administered by continuous intravenous infusion in accordance with approved prescribing information or institutional prescribing guidelines at each study site. The primary efficacy outcome measure included the occurrence of any of the following up to 30 days after study drug discontinuation: new-onset or worsening thrombosis requiring discontinuation of study drug; amputation; or all-cause mortality. Other outcomes that were assessed included platelet recovery, bleeding, and pharmacoeconomic parameters. In addition, adverse events and other safety parameters were evaluated. Study enrollment began in November 2008 and ended in December 2009 due to slow enrollment (N = 16). The study results will be published separately. CONCLUSION: The results from the PREVENT-HIT study should enhance understanding of the comparative clinical and economic utility of desirudin and argatroban in patients with HIT with or without thrombosis.

The heparin-induced thrombocytopenia task force model: implementing quality improvement and economic outcome initiatives.

Heparin-induced thrombocytopenia (HIT) is a costly but potentially preventable complication associated with the use of heparin. Based on a 1% to 3% incidence of HIT, the total cost and potential financial loss due to HIT complicating open-heart surgery is estimated to range from over 100 to 300 million dollars and from over 33 to 100 million dollars annually, respectively, in the United States. To minimize the personal and economic cost of HIT, the Charleston Area Medical Center (CAMC) HIT Task Force developed institutional guidelines for diagnosis and treatment, educated medical staff and patients, and took measures institution-wide to reduce patient exposures to heparin.

Primary, extranodal, follicular non-Hodgkin lymphoma of the gallbladder: case report and a review of the literature.

We report the first case of isolated primary extranodal non-Hodgkin lymphoma follicular grade 2 limited to the gallbladder, found in the laparoscopic cholecystectomy specimen from a 70 year old woman with symptomatic cholelithiasis. The pericystic duct lymph node, surgical margins, and other lymph nodes, were not involved with lymphoma. According to the medical literature in English language, mucosa associated lymphoid tissue lymphoma (6 cases) is the most frequent type (38%) of primary gallbladder lymphomas (15 reported cases plus our case). Our case demonstrates that follicular lymphoma can be limited to the gallbladder, and confirm that it can occur in an organ normally devoid of lymphoid tissue.
