Case ReportsSevere infusion reactions to brentuximab vedotin in two patients with Hodgkin lymphoma previously treated with allogeneic stem cell transplantation.
Brentuximab vendotin is a monoclonal antibody approved in August 2011 for use in patients with Hodgkin disease and a rare systemic lymphoma known as anaplastic large cell lymphoma. Brentuximab is approved in patients with Hodgkin disease who have failed autologous transplantation or after failure of at least two prior multi-agent chemotherapy regimens but has not been studied following allogeneic transplantation. Four patients with relapsed Hodgkin disease have been treated at our institution with at least two doses of brentuximab vendotin. ⋯ Both patients with reactions had relapsed following allogeneic stem cell transplants, while neither of the patients who tolerated the infusions had undergone transplantation. We report our experience with brentuximab vendotin-treated patients at our institution, focusing on the two post-allogeneic patients who experienced multiple significant infusion reactions. This report evaluates possible mechanisms behind their reactions, including previous allogeneic stem cell transplantation as a likely precipitating factor.

A retrospective review of antiemetic use for chemotherapy-induced nausea and vomiting in pediatric oncology patients at a tertiary care center.
Chemotherapy-induced nausea and vomiting are the most dreaded and distressing side effects for cancer patients undergoing chemotherapy treatment. These side effects have a significant impact on the patients' quality of life and can interfere with their ability to receive intensive chemotherapy regimens. With the recent advances in antiemetic pharmacotherapy and supportive care, the current treatments for chemotherapy-induced nausea and vomiting, when used appropriately, have become highly effective in mitigating these adverse effects. ⋯ Inadequate antiemetic prophylaxis is associated with a high risk of breakthrough emesis particularly with high emetogenic chemotherapy regimens. Standardizing antiemetic prophylaxis based on emetogenic level could reduce breakthrough emesis and improve the quality of life in pediatric oncology patients.

Evaluation of clinical pharmacists' follow-up service in an oncology pain clinic.
Patients who present with pain in an oncology setting are often complex and require a multidisciplinary approach for symptom control. The Pain and Symptom Control Clinic at Tom Baker Cancer Center includes two pharmacists who participate in weekly multidisciplinary clinics and provide a follow-up service to patients. ⋯ The inclusion of pharmacists in the Pain and Symptom Control Clinic is favored by patients and health care professionals and provides increased efficiency to the clinic.

Case ReportsSelective ophthalmic intra-arterial melphalan therapy for advanced retinoblastoma: implementation and outcomes of a new chemotherapy protocol.
Retinoblastoma is a relatively uncommon childhood tumor. If untreated, RB grows to fill the eye and destroys the ocular globe's internal architecture. Metastatic spread usually begins after the first 6 months, and death occurs within a matter of years. ⋯ In our hospital, pediatric oncologists asked the Pharmacy Department for assessment in order to implement a new chemotherapy protocol for the treatment of advanced intraocular elegible retinoblastoma cases using melphalan administered directly through the ophthalmic artery. In this paper, we describe the protocol implementation carried out by our collaborative interdisciplinary team as well as the clinical outcomes of five cases treated with ophthalmic intra-arterial melphalan therapy. Oncology pharmacists can contribute with their knowledge to the implementation process of new collaborative practice protocols recommending doses, predicting possible adverse effects and assessing about drug stability and elaboration, packaging and administration methods.

Adherence to hepatitis B screening and prophylactic lamivudine for prevention of rituximab-associated hepatitis B reactivation.
Treatment with rituximab can be associated with hepatitis B reactivation leading to fulminant hepatitis and sometimes fatal hepatitis. The manufacturer has recommended screening the high-risk patients and monitoring hepatitis B virus carriers during and several months after the therapy. Prophylaxis with lamivudine has been recommended to prevent reactivation in hepatitis B virus carriers receiving rituximab. An institutional guideline was developed and implemented. This study evaluated the adherence to these clinical guidelines of hepatitis B screening in patients receiving rituximab-based treatment, the use of lamivudine prophylaxis, and the prevalence of positive hepatitis B virus surface antigen in this patient population in southeast Michigan. ⋯ The prevalence of hepatitis B virus surface antigen positivity is low in this study; however, antibody to hepatitis B virus core antigen positivity is high. Education to clinicians is warranted to increase awareness and further improve adherence to the clinical guidelines.
