Combination effect of antitumor agents, including cyclocytidine and cytosine arabinoside, was evaluated on the conception of pharmacological synergism and not of therapeutic synergism. Ascites sarcoma-180 and L-1210 leukemia were used as tumor systems. In sarcoma-180 system, combinations of
Histiocytic sarcoma, a rare hematopoietic neoplasm with evidence of histiocytic differentiation, is often refractory to conventional chemotherapy and radiotherapy, and its prognosis is generally dismal. The optimal management of this malignancy has not been established. We report a case of
BACKGROUND
The presence of tumor-specific mutations in the cancer genome represents a potential opportunity for pharmacologic intervention to therapeutic benefit. Unfortunately, many classes of oncoproteins (e.g., transcription factors) are not amenable to conventional small-molecule screening.
The chemotherapeutic activity of five cytostatic drugs was investigated experimentally in monotherapy and in two-drug combinations, using Yoshida sarcoma cells implanted into the wall of the glandular stomach of Sprague-Dawley rats. In monotherapy, the antibiotic agent mitomycin C and the
Four cases of central nervous system involvement by granulocytic sarcoma (three intracranial and one paraspinal) in children with acute nonlymphocytic leukemia (FAB M1 or M2 subtype) are presented, and therapeutic modalities are discussed. All tumors were noted at initial presentation with diagnosis
Experience with high-dose cytosine arabinoside (HDAC) in pediatric solid tumors is limited. Sixteen children with solid tumors resistant to conventional therapies were registered in a pilot Pediatric Oncology Group (POG) study that required the administration of HDAC at 3 g/m2 every 12 hours for
BACKGROUND
Although lymphoproliferative disorders are well-described and known entities post renal transplantation, acute myeloid sarcoma is a rare if ever reported occurrence in this setting. Immunosuppressive therapy is thought to be the main culprit in these cases.
METHODS
A 51-year-old man
A novel murine tumor resistant to cis-diamminedichloroplatinum (cisplatin, DDP) was obtained (M5/DDP) after 22 passages in which mice bearing the ovarian reticular cell sarcoma M5076 (M5) were treated with DDP. Although DDP conserved some inhibitory activity on growth of M5/DDP, it was much less
Serum-free growth of Ewing's sarcoma (ES) and primitive peripheral neuroectodermal tumour (pPNET) cell lines was achieved by supplementing a basal medium with insulin-like growth factor-I (IGF-I). These cultures were used to investigate the sensitivity of 3 ES (EW-2, RD-ES, SK-ES-1) and 3 pPNET
An immunomodulatory polysaccharide-rich substance (Noni-ppt) from the fruit juice of Morinda citrifolia has been found to possess both prophylactic and therapeutic potentials against the immunomodulator sensitive Sarcoma 180 tumour system. The antitumour activity of Noni-ppt produced a cure rate of
Granulocytic sarcomas are malignant solid tumors composed of poorly differentiated myeloid cells that occur in association with myelocytic leukemia. The clinicopathologic characteristics of granulocytic sarcomas that presented in the oral mucosa and in the facial, scalp and neck skin of 8 patients
