OBJECTIVE. The purposes of this article are to review the causes of pelvic congestion syndrome and the imaging used to make the diagnosis and to summarize the treatment options. CONCLUSION. Pelvic congestion syndrome is one of many causes of chronic pelvic pain. It is thought to arise from ovarian and pelvic venous incompetence. Findings from various noninvasive imaging studies, such as Doppler ultrasound and MRI, in association with the clinical symptoms are critical in establishing the diagnosis.
Purpose
Cyclin‐dependent kinase (CDK) 4/6 inhibitors are integral treatment for advanced hormone receptor positive breast cancer; however, venous thromboembolic events (VTE) occurred in 1%‐5% of clinical trial patients. Thrombosis rates in the real‐world setting remain unclear. We aimed to define the rate of thromboembolic events, risk factors for thrombosis on CDK 4/6 inhibitors and evaluate the Khorana VTE risk score as a predictive tool for VTE in patients on CDK 4/6 therapy.
Methods
Multicenter retrospective analysis of adult breast cancer patients prescribed palbociclib, ribociclib, or abemaciclib. The primary endpoint was thrombosis during treatment or within 30 days of CDK inhibitor discontinuation. Cox regression was used to model time‐to‐thrombosis, starting from a patient's initiation of CDK 4/6 therapy. The extended Kaplan‐Meier method and Cox modeling were used to assess the effect of time‐varying thrombosis status on overall survival.
Results
Two hundred and sixty‐six patients were included (89% on palbociclib, 14% on abemaciclib, 7% on ribociclib). Twenty‐nine thrombotic events occurred in 26 (9.8%) women. Of these events, 72% were venous and 34% were arterial. The 1‐year incidence of thrombosis was 10.4% overall, 10.9% on palbociclib, 8.3% on ribociclib, and 4.8% on abemaciclib. Hemoglobin less than 10 g/dL was a statistically significant predictor of thrombosis (HR 3.53, P: .014). Khorana score ranged from 0‐3, with the majority between 0 and 1 and was not predictive of VTE. Thrombosis was associated with reduced overall survival (HR 1.28, P: .128, median 7.3 months) compared to not having a CDK‐associated clot (median 35.7 months).
Discussion
VTE in our analysis is higher than reported in clinical trials and arterial thrombosis comprised over one‐third of events. The highest incidence was with palbociclib, followed by ribociclib. Khorana score did not predict VTE risk. Larger, real‐world studies are needed. The role for prophylactic anticoagulation is yet to be defined in this patient population.
Objective The purpose of this study was to identify trends in oncology care that allow one to forecast workforce supply and demand, the training and skills needed by the oncology pharmacist for the likely future of oncology care. Methods Interviews were conducted with experienced oncology pharmacists in leadership roles at 20 organizations balanced by geographic region and type of practice site (academic or community/ambulatory). Results were analyzed using descriptive statistics and theme identification. Results Practice sites differed widely in numbers of patient visits, practitioner/patient ratios, residency program presence, and other structural features. Despite this, the majority reported an expectation of growth in cancer patients, oncology physicians, oncology pharmacists, pharmacy technicians, oncology nurses, and advanced practice practitioners in the next two to five years. Fifty percent of sites currently support Post Graduate Year 2 (PGY2) oncology residencies. At least 50% reported routine pharmacist involvement in 12 clinical functions. More future involvement was predicted for immunotherapy (80%) and oral oncolytic therapy (90%). Interprofessional involvement was reported for a broad variety of practice-related committees and patient education teams. Limited pharmacist involvement in credentialing, quality measurement, and value-based reimbursement systems was found. Conclusion Anticipated increases in demand for oncology pharmacists strongly suggest the need for more PGY2 oncology residency programs and on-the-job oncology training programs. Oncology pharmacists are currently involved in many clinical and administrative functions including multidisciplinary management. While a core set of clinical functions has been identified, oncology pharmacists must prepare for the increased use of oral oncology agents and immunotherapy. Pharmacist involvement in value-based reimbursement and other data-based quality outcome measurements should be increased to optimize involvement in team-based patient care.
