Nursing care of the patient receiving chemotherapy includes patient education and drug administration, as well as ongoing assessment, early identification, and intervention for side effects. Two liposomal anthracyclines are available in the United States, pegylated liposomal doxorubicin (Doxil/Caelyx [PLD]) and liposomal daunorubicin (DaunoXome [DNX]). Because of their unique liposomal formulations, the administration and toxicity profiles of these agents are different from those of conventional anthracyclines, as well as each other. Common severe toxicities of conventional anthracycline treatment such as nausea/vomiting, alopecia, and neutropenia are less frequent and less severe during liposomal anthracycline treatment, and cumulative-dose cardiotoxicity is rare, particularly with PLD therapy. Dose-related adverse events with liposomal anthracycline therapy include stomatitis and neutropenia, and more frequent doses of PLD are associated with hand-foot syndrome. Ongoing nursing assessment, patient education, and adjustments to the dose or dose-schedule can reduce the severity or frequency of these toxicities. Nurses must be aware of the unique characteristics of liposomal anthracycline therapy to provide optimal patient education and nursing care.

A systematic review was performed to determine whether first-line dose-intensive chemotherapy supported by growth factor or autologous bone marrow/stem cell transplantation improves response rate, time-to-disease progression, or survival compared with standard-dose chemotherapy in patients with inoperable, locally advanced, or metastatic soft tissue sarcoma. The MEDLINE, EMBASE, and Cochrane Library databases were searched. Three randomized trials (2 phase 3, 1 phase 2), 12 phase 2, and 5 phase 1 dose-escalation trials were located. One randomized trial (N=314) did not detect significant differences in response rate (P=.65) or survival (log-rank P=.98) between high-dose doxorubicin plus ifosfamide with granulocyte macrophage colony-stimulating factor and doxorubicin plus ifosfamide at standard doses. Progression-free survival, however, was significantly longer in the high-dose arm (log-rank P=.03). Higher rates of thrombocytopenia, infection, grade 3 of 4 asthenia, and stomatitis were observed with high-dose compared with standard-dose chemotherapy. Preliminary results from a second randomized trial (N=162) indicated no benefit with respect to tumor response for an intensified mesna, doxorubicin (Adriamycin), ifosfamide, and dacarbazine regimen with granulocyte colony-stimulating factor support compared with standard doxorubicin, ifosfamide, and dacarbazine. Grade 4 thrombocytopenia was significantly higher with the high-dose regimen. Four phase 2 trials of high-dose regimens observed tumor response rates greater than 50%. Phase 1 trials reported dose-limiting toxicity for dose-intensive chemotherapy regimens. On the basis of the available evidence, high-dose chemotherapy with growth factor or autologous bone marrow/stem cell transplantation should not be used in the routine treatment of patients with inoperable, locally advanced, or metastatic soft tissue sarcoma.
