OBJECTIVE
Uterine sarcomas are a heterogeneous group of tumors with a propensity for metastasis and resistance to conventional therapy. Recent success in the treatment of other solid tumors with the targeted tyrosine kinase inhibitor imatinib mesylate offers new avenues for investigation. The
Recombinant human interferon alpha A/D (IFN alpha A/D) is known to be as active on murine cells as on human cells. We studied the antitumor effect of pure IFN alpha A/D on Meth-A sarcoma subcutaneously transplanted into female syngeneic BALB/c mice. When administered systematically
Ascites sarcoma 180 (S180A) is a transplantable tumor which causes hypercalcemia in tumor-bearing mice, and stimulates bone resorption without parathyroid hormone-like activity. In the present study, parathyroid hormone-related protein (PTHrP) mRNA could not be detected in total RNA from S180A
We have previously described an in vitro sensitization (IVS) procedure which enabled the generation of therapeutic T cells from tumor-bearing mice for adoptive immunotherapy. The procedure involved culture of tumor-draining lymph node (TDLN) cells with irradiated tumor in the presence of
To determine the safety, maximum tolerated dose, and preliminary efficacy of concomitant interferon-alpha and zidovudine therapy in AIDS-related Kaposi's sarcoma (KS), 56 patients with biopsy-proven KS and documented human immunodeficiency virus type 1 (HIV) infection were enrolled into a phase I
A prospective clinical trial of concomitant interferon-alpha 2b and etoposide was conducted in 24 previously untreated patients with epidemic Kaposi's sarcoma. Eight of 21 evaluable patients (38%) achieved either a complete response (1 patient) or a partial response (7 patients). None of the
Alpha interferon has been the most widely studied biologic response modifier for the treatment of Kaposi's sarcoma (KS) associated with acquired immune deficiency syndrome (AIDS). At San Francisco General Hospital's AIDS Clinic, three sequential trials of recombinant interferon alfa-2b (Intron A)

OBJECTIVE
The effects of conditioned media from the methylcholanthrene (MCA) fibrosarcoma on hepatocyte albumin production and amino acid transport were studied. The authors characterized a factor responsible for the observed effects and investigated the role of tumor necrosis factor-alpha
The effect of recombinant tumor necrosis factor-alpha (rTNF), injected directly into the tumor, was evaluated in a Phase I/II study of 27 patients with AIDS-associated Kaposi's sarcoma (KS). The maximally tolerated intralesional dose was less than 100 micrograms/m2 and the recommended intralesional
A 71-year-old female patient with classic Kaposi sarcoma (sarcoma idiopathicum haemorrhagicum multiplex) of the lower legs and one hand was treated with intralesional recombinant interferon alpha 2b. After 6 consecutive weeks of intratumoral injection of 1-3 million IU interferon-alpha 2b (Intron A)
A 23-year-old woman with an alveolar soft-part sarcoma of her calf with pulmonary metastases unresponsive to chemotherapy is described. Interferon (IFN) alpha-2b induced an impressive tumour response still ongoing after IFN treatment had to be stopped because of a psychosis. An explanation of this
This article reviews developments over nearly 15 years in the application of interferon-alpha (IFN-alpha) to the treatment of Kaposi's sarcoma (KS) in patients with acquired immunodeficiency syndrome (AIDS). The initial success of IFN treatment for selected patients with AIDS-associated KS occurred
We have shown previously that isolated limb perfusion (ILP) in sarcoma-bearing rats results in high response rates when melphalan is used in combination with tumour necrosis factor alpha (TNF-alpha). This is in line with observations in patients. Here we show that ILP with doxorubicin in combination
The RNA-dependent DNA polymerase purified from B77 avian sarcoma virus exhibited two distinct DNA-processing activities. The alpha and beta 2 isoenzymes possessed an endodeoxyribonuclease activity capable of nicking simian virus 40 superhelical DNA, whereas the alpha beta isoenzyme performed as an
