PHAR announced that results from the first study to assess the clinical utility of the DCIS Score Assay in management of DCIS will be presented at American Society of Clinical Oncology (ASCO) Annual Meeting. Clinicians and breast cancer patients must decide among multiple treatment options including breast conserving surgery, mastectomy, partial or whole breast radiation, and hormonal manipulation. Treatment recommendations are usually made using clinicopathologic factors to estimate average local recurrence risk for similar patients. The validated Oncotype® DX 12-gene assay for DCIS gives additional, independent, individual estimates of 10-year risk In association with 10 cancer centers throughout the United States, PHAR conducted a prospective observation study on the impact of the DCIS Score result on radiation treatment recommendations for patients with DCIS. The study results will be presented at ASCO’s 50th Annual Meeting in Chicago, IL, and can be viewed here.
PHAR partnered with researchers at Genentech Inc. to study the relationship between the Healthcare Effectiveness Data and Information Set (HEDIS) and Asthma-Related Outcomes. Patients with low asthma medication ratio (AMR< 0.5) had worse asthma control by multiple measures including hospitalization/ED visits, OCS use, and SABA use. The number of asthma-related office visits was also slightly higher for low AMR patients. The findings support the use of AMR as a quality of care measurement for patients with persistent asthma. The Academy of Managed Care Pharmacy awarded this study a silver medal at their annual meeting. The poster presented at the AMCP Annual Meeting can be viewed here.
Dr. Gordon Sun of PHAR, along with researchers from the University of Michigan and VA Center for Clinical Management Research compared postoperative technical, quality-of-life, and cost outcomes following either robotic or open thyroidectomy for thyroid nodules and cancer. They examined relevant controlled trials, comparative effectiveness studies, and cohort studies for eligible publications to calculate the pooled relative risk for key postoperative complications, mean differences for operative time, and standardized mean differences for length of stay using random effects models. They found that the robotic approaches may introduce the risk of new complications and require longer operative times. The study can be read here.
Despite the availability of numerous antiepileptic drugs, some epilepsies remain resistant to treatment. We compared utilization and costs in patients with uncontrolled epilepsy to those with stable epilepsy using commercial insurance claims data. We found patients with uncontrolled epilepsy use more services and incur higher costs compared with those with stable epilepsy. Epilepsy-related costs accounted for <50% of the total costs, suggesting that comorbid conditions and/or under identification of utilization may substantially contribute to costs. This study was published in Epilepsy & Behavior and can be read here.
Given the small magnitude of benefit with adjuvant therapy in stage II colon cancer, chemotherapy is often selected for patients based on their physicians’ subjective assessment of clinical factors. To help guide oncologists’ adjuvant treatment recommendations for standard risk patients where other existing markers are not informative, the 12-gene colon cancer Oncotype DX® Recurrence Score® Assay was developed. The investigators at PHAR in collaboration with Genomic Health studied the effects of the assays by conducting physician surveys. U.S. medical oncologists who ordered the assay for ≥3 stage II colon cancer patients were asked to complete a web-based survey regarding their most recent such patient. They found that the use of the Oncotype DX assay is associated with an overall change of nearly one in three treatment recommendations for stage II colon cancer patients, and that it may lead to more appropriate use of adjuvant treatment. The study can be read here.
There are no clinical guidelines on best practices for the use of bronchoscopy and esophagoscopy in diagnosing head and neck cancer. Dr. Gordon Sun of PHAR partnered with investigators from the University of Michigan and the University of Pennsylvania to examine variation in the use of bronchoscopy and esophagoscopy across hospitals in Michigan through a retrospective cohort study of the Michigan State Ambulatory Surgery Database. The authors found that patients with head and neck cancer who are undergoing diagnostic laryngoscopy are much more likely to undergo concurrent bronchoscopy and esophagoscopy at low- and medium-volume hospitals than at high-volume hospitals.

Experts from Eisai presented findings of a PHAR/Eisai study on chemotherapy-induced nausea and vomiting (CINV) medication at the MASCC/ISOO International Symposium on Supportive Care in Cancer, held in Berlin, Germany. The investigators compared the cost and occurrence of CINV between patients who were only prescribed palonosetron and patients who were prescribed the generic alternative in combination with other oral medication. The study found that patients treated with palonosetron alone had a significantly lower risk of CINV, and lower CINV-related charges, than patients treated with generic alternatives.

Researchers at PHAR, in conjunction with experts from Novartis Pharmaceuticals Corporation, presented the results of several studies on Cushing’s disease at the Endocrine Society’s 95th Annual Meeting on June 19th, 2013. Cushing’s disease, a pituitary disorder, is poorly studied because of its rarity. The PHAR research team reported on the incidence, treatment patterns, and annual economic burden associated with the disease–topics on which very little was previously known. The three posters presented at ENDO can be viewed by clicking the links below:
The PHAR researchers presented three posters at the 18th Annual International Meeting of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) in New Orleans, LA. A summary and link to each poster can be found below:
- A Markov cohort model assessed the clinical and economic trade-offs of two products (EVG/cobi/FTC/TDF and EFV/FTC/TDF) in first-line antiretroviral therapy in US adults and found that EVG/cobi/FTC/TDF was not cost effective in the base case compared with EFV/FTC/TDF for first-line HIV treatment. The poster can be viewed here.
- A comparison of healthcare costs and utilization between epilepsy patients treated with Long-Acting and Short-Acting antiepileptic drug (AED) monotherapy found that LA AED users incur a lower economic burden than SA AED. The poster can be viewed here.
- An evaluation of commercially-insured patients with Cushing’s disease, a rare disorder resulting from excessive exposure to glucocorticoids, found a substantial economic burden in these patients with up to $35,000 incurred annually in overall healthcare costs, of which $31,995 are for medical costs. The poster can be viewed here.
According to Andrew M. Kaunitz, MD, Editor in chief of Journal Watch, Women’s Health, a study by PHAR researchers demonstrates that “except in women with mutations that raise risk for ovarian cancer, bilateral oophorectomy should not be performed at hysterectomy for benign indications.” Dr. Kaunitz is is Professor and Associate Chair of the Department of Obstetrics and Gynecology at the University of Florida College of Medicine–Jacksonville.
