Subcutaneous Administration: Evolution, Challenges, and the Role of Hyaluronidase.

BACKGROUND: The subcutaneous (SC) route has evolved significantly. More than two dozen chemotherapy and supportive therapies have been approved for use in the oncology setting. Several IV therapies have been approved for the SC route and require a significantly higher volume than historical maximum limits. Differences exist in how these drugs are administered as compared to older chemotherapy agents. OBJECTIVES: The purpose of this article is to provide a brief history of the SC route and describe its role in cancer treatment. The use of recombinant hyaluronidase is reviewed within the context of SC monoclonal antibodies. Proper administration techniques and interventions for reducing patient discomfort are discussed. METHODS: Sentinel medical texts, pharmacokinetic studies, manufacturer's recommendations, and peer-reviewed articles were examined. FINDINGS: The SC route offers several advantages over the oral and IV routes. A clear understanding of anatomical site selection and injection techniques is beneficial for providing requisite patient education.

Hazardous Drug Contamination: Presence of Bathroom Contamination in an Ambulatory Cancer Center.

BACKGROUND: Many hazardous drugs (HDs) are excreted in urine and feces, and evidence has shown that bathrooms of patients receiving chemotherapy at home are contaminated with HDs. However, little information exists on bathroom contamination in ambulatory clinics where HDs are administered. OBJECTIVES: This project aimed to determine the presence of HD residue in the patient and staff bathrooms of an ambulatory cancer center. METHODS: A quality improvement project was initiated to examine potential contamination by the HDs 5-fluorouracil and oxaliplatin in a patient bathroom and a secured badge-access staff bathroom in the infusion department of an ambulatory comprehensive cancer center. Twice-daily wipe testing was conducted on the floor in front of the toilet and the flush handle for five consecutive days. FINDINGS: Sixty-five percent of the samples from the floor of the patient bathroom were positive for at least one of the HDs. In the staff bathroom, 35% of the floor samples were positive for at least one HD. None of the flush handle samples were above the level of detection.
