RESUMEN

Education is the main avenue for disseminating new research findings into clinical practice. Understanding factors that affect translation of research into practice may help cancer educators design programs that facilitate the time it takes for research-indicated practices to become standard care. To understand various factors, the National Cancer Institute (NCI) Office of Education and Special Initiatives (OESI)(1) with individual cooperation from Oncology Nursing Society (ONS), American Society of Clinical Oncology (ASCO), and Association of Oncology Social Work (AOSW) administered a Practitioner Information Needs survey to five different types of practitioners involved in cancer care. While most of the 2,864 practitioners (83%) agreed they had access to current practice information, practitioners in large practice settings were more likely to report having access to research than those small practice settings. However, only 33% indicated that they had adequate time to access the information. Colleagues or experts within the organization were cited as the most frequently relied on information resource (60%), and peer-reviewed journals were cited as second (57%). Overall, 66% strongly or somewhat agreed that their organizations exhibit effective change management practices. A majority (69%) agreed that implementation of new practices is hindered by the lack of available staff time. Financial factors and the characteristics of the information presented were also believed to be factors contributing to research implementation. Group differences were observed among practitioner groups and practice settings for some factors.

RESUMEN

Objective We describe an apparently unique case of an extra-uterine leiomyoma in the cervical paraspinal tissue including its evaluation and management. Methods A 14-year-old girl was referred to the neurology clinic for an abnormal head CT following a concussion. MRI revealed a homogenously enhancing left cervical paraspinal mass. The patient underwent complete resection and subsequent genetic testing and counseling were obtained to determine the presence of Li-Fraumeni Syndrome (LFS) or Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) mutations. Result Histopathological examination proved that the tumor was a benign leiomyoma. Genomic testing for Fumarate Hydratase Gene, HLRCC, TP53 mutations or deletions, and LFS sequencing were negative. Further testing showed no immunosuppression. Conclusions To the best of our knowledge, this is the only case of paraspinal leiomyoma to have been reported to date. We emphasize the importance of considering immunosuppression, LFS, or HLRCC as an underlying cause in extra-uterine leiomyata.

RESUMEN

BACKGROUND: In the United States, hospice agencies are required to convene interdisciplinary group (IDG) meetings no less frequently than every 15 days to review patients' care plans. Challenges associated with information sharing during these meetings can impede efficiency and frustrate attendees. OBJECTIVES: We sought to examine information sharing in the context of hospice IDG meetings as a first step toward developing an informatics tool to support interdisciplinary collaboration in this setting. Specifically, we wanted to better understand the purpose of information sharing in IDG meetings and determine the type(s) of information required to fulfill that purpose. Methods, Setting, and Participants: In this qualitative descriptive study, we analyzed video recordings of care plan discussions (n = 57) in hospice IDG meetings and individual interviews of hospice providers (n = 24). RESULTS: Data indicated that sharing physical, psychosocial, and spiritual information is intended to optimize hospice teams' ability to deliver whole-person care that is aligned with patient and family goals and that satisfies regulatory requirements. CONCLUSION: Information sharing is a key function of hospice teams in IDG meetings. Informatics tools may optimize IDG meeting efficiency by succinctly presenting well-organized and required information that is relevant to all team members. Such tools should highlight patient and family goals and ensure that teams are able to satisfy regulatory requirements.

RESUMEN

The purpose of this study was to develop a safe and efficacious drug delivery platform for sustained release of cisplatin after locoregional administration. We successfully synthesized hyaluronan-cisplatin nanoconjugates (HA-Lys-Pt) using an N-Ac-lysine linker, which formed a thermodynamically stable five-membered ring with the platinum. The conjugate was characterized for release kinetics, in vitro anti-proliferative activity, degradability, impurity content, formation of Pt-DNA adducts, pharmacokinetics, tolerability in rodents and canines, and for efficacy in rodents. The 75 kD HA-Lys-Pt (75HA-Lys-Pt) sustained release of platinum with a 69 h half-life in phosphate buffered saline without substantial burst release. Compared to intravenous cisplatin, subcutaneously injected 75HA-Lys-Pt formed 3.2-fold more Pt-DNA adducts in rat peripheral blood mononuclear cells compared to intravenous cisplatin over 96 h. Subcutaneous 75HA-Lys-Pt was tolerable in rats at 40 mg/kg (4 × LD50 of conventional cisplatin) and resulted in 62.5% partial response and 37.5% stable disease in murine xenografts of head and neck squamous cell cancer (20 mg/kg/wk × 3 weeks). 75HA-Lys-Pt demonstrated extended tmax and improved area-under-the-curve compared to cisplatin in rats and canines. Canine safety was demonstrated by liver enzyme and electrolyte levels, complete blood count, and urinalysis.

RESUMEN

OBJECTIVE To conduct a phase I-II clinical trial of hyaluronan-cisplatin nanoconjugate (HA-Pt) in dogs with naturally occurring malignant tumors. ANIMALS 18 healthy rats, 9 healthy mice, and 16 dogs with cancer. PROCEDURES HA-Pt was prepared and tested by inductively coupled plasma mass spectrometry; DNA-platinum adduct formation and antiproliferation effects of cisplatin and HA-Pt were compared in vitro. Effects of cisplatin (IV) and HA-Pt (SC) in rodents were tested by clinicopathologic assays. In the clinical trial, dogs with cancer received 1 to 4 injections of HA-Pt (10 to 30 mg/m(2), intratumoral or peritumoral, q 3 wk). Blood samples were collected for pharmacokinetic analysis; CBC, serum BUN and creatinine concentration measurement, and urinalysis were conducted before and 1 week after each treatment. Some dogs underwent hepatic enzyme testing. Tumors were measured before the first treatment and 3 weeks after each treatment to assess response. RESULTS No adverse drug effects were detected in pretrial assessments in rodents. Seven of 16 dogs completed the study; 3 had complete tumor responses, 3 had stable disease, and 1 had progressive disease. Three of 7 dogs with oral and nasal squamous cell carcinoma (SCC) that completed the study had complete responses. Myelosuppression and cardiotoxicosis were identified in 6 and 2 dogs, respectively; none had nephrotoxicosis. Four of 5 dogs with hepatic enzymes assessed had increased ALT activities, attributed to diaquated cisplatin products in the HA-Pt. Pharmacokinetic data fit a 3-compartment model. CONCLUSIONS AND CLINICAL RELEVANCE HA-Pt treatment resulted in positive tumor responses in some dogs, primarily those with SCC. The adverse effect rate was high. IMPACT FOR HUMAN MEDICINE Oral SCC in dogs has characteristics similar to human head and neck SCC; these results could be useful in developing human treatments.
