OBJECTIVE The aim of this retrospective study was to evaluate the feasibility and efficacy of response to continuous-infusion ifosfamide and doxorubicin combination as second-line chemotherapy for patients with recurrent or refractory osteosarcoma. MATERIALS AND METHODS Eighteen recurrent or refractory osteosarcoma patients who were treated with continuous-infusion ifosfamide and doxorubicin ...

PURPOSE In osteosarcoma, aggressive preoperative and postoperative multidrug chemotherapy given to all patients has improved patient survival rate to the present level of approximately 60%. However, no tumor marker is available that reliably can identify those patients who will or will not respond to chemotherapy. EXPERIMENTAL DESIGN In an attempt to find leads to such markers, we have obtain...

The in vivo cytokinetic effects on bone marrow cells from 19 patients with leukemia and lymphoma were inves tigated following a 5-day continuous i.v. infusion of ifosfamide (a congener of cyclophosphamide) at a daily dose of 1.0 to 1.8 g/sq m. There were 8 patients without bone marrow involvement by tumor cells at the time of study, and 11 patients had various degrees of neoplastic re placement...

BACKGROUND Some studies have shown a somatic nociceptive response due to the activation of transient receptor potential A1 channels (TRPA1), which is modulated by the TRPA1 antagonist HC-030031. However, a few studies report the role of TRPA1 in visceral pain. Therefore, we investigated the participation of TRPA1 in visceral nociception and the involvement of nitric oxide, the opioid system and...

Purpose Because we had observed in the synovial sarcoma subgroup of a broad phase III advanced soft tissue sarcoma study a significantly greater objective regression rate from ifosfamide+doxorubicin (88%) than from doxorubicin alone (20%) (P = 0.02), the Eastern Cooperative Oncology Group (ECOG) decided to further assess this two drug combination in a subsequent Phase II study.Patients Between ...

INTRODUCTION Ifosfamide is a chemotherapy agent infrequently associated with liver toxicity. To the best of our knowledge, this report is the first to describe serious liver toxicity associated with ifosfamide used in combination with doxorubicin that caused acute but fully reversible liver failure and encephalopathy. This report reviews the possible mechanisms by which ifosfamide causes this a...

Although approved for the treatment of pancreatic cancer, the chemotherapeutic agent ifosfamide is not an effective therapy for this type of tumour. Ifosfamide must be activated by cytochrome P450 (P450) enzymes in the liver, initially to a short lived intermediate and then to toxic metabolites that are subsequently distributed by the circulatory system. Particularly for pancreatic cancer, this...

Etoposide and ifosfamide are chemotherapeutic agents used frequently in the treatment of sarcomas and hematologic malignancies. Ocular side effects are rarely reported. We describe a case of a patient on etoposide and ifosfamide who presented with unilateral vision loss, anemia, and thrombocytopenia. The patient was found to have a large subinternal limiting membrane hemorrhage in the right eye...

Uterine sarcomas are rare, high-risk malignancies. Expert histologic review is important for accurate diagnosis. For high-grade leiomyosarcomas, the risk of recurrence is high after complete resection of uterus-limited disease; however, no adjuvant therapy has been proven to improve survival. Chemotherapy regimens with efficacy in treating advanced uterine leiomyosarcoma include gemcitabine-doc...
