Of 131 patients with primary Ewing's sarcoma (ES) with extremity locations, treated between April 1972 and May 1987, 13 had amputation; 56 had a local resection with 31 (55%) requiring radiation therapy (RT) as an adjuvant to local therapy. Sixty-two of 131 patients (47%) had RT only. Local
An 11-month-old white female with a three-month history of swelling of soft tissue around the right eye presented with a proptotic globe and marked limitation of motility. A CT scan showed a soft-tissue mass in the orbit, which was biopsied and examined by light and electron microscopy. The specimen
DNA synthesis was studied in mouse ascites sarcoma cells using a permeable cell system. The sarcoma was induced by the Schmidt-Ruppin strain of Rous sarcoma virus. The cells were made permeable to nucleoside triphosphates by treatment with a hypotonic buffer containing 10 mM Tris Cl, 4 mM MgCl2, 1
The chloride salts of lithium (Li+) and cesium (Cs+) were evaluated for their ability to influence the growth of Sarcoma I implants in A/J mice. The administration of daily doses of either 1 or 3 mEq/kg CsCl to these mice reduced the incidence and size of tumor implants. This effect was not apparent
The effect of cesium therapy on various cancers is reported. A total of 50 patients were treated over a 3 year period with CsCl. The majority of the patients have been unresponsive to previous maximal modalities of cancer treatment and were considered terminal cases. The Cs-treatment consisted of
The capacity of RNA subunits of Schmidt-Ruppin Rous sarcoma virus to bind (dT)n was studied by cesium sulfate density gradient centrifugation, sucrose gradient centrifugation, or polyacrylamide gel electrophoresis. Two classes of subunits were observed. In agreement with previous reports, 60 to 70%
The effect of pretreatment with CsCl on mice bearing sarcoma I implants was studied as a function of duration of treatment period, life span and tissue Cs+ and K+ levels. Treatment with CsCl for 14 consecutive days prior to sarcoma implantation resulted in initial reduction of the tumor-mediated
Previously, we reported (Fritsch and Temin, J. Virol. 21:119-130, 1977) that infectious viral DNA was not present in spleen necrosis virus-infected stationary chicken cells. However, a stable intermediate was present in such infected stationary cells as evidenced by the appearance of infectious
OBJECTIVE
Soft-tissue sarcomas most frequently metastasize to the lung. Surgical resection of pulmonary metastases is the primary treatment modality. Although lobectomy is widely acknowledged as the standard procedure to treat primary pulmonary tumors, the standard for pulmonary metastases is not
The nasal cavity of 67 dogs with malignant nasal neoplasia was treated with radiation. Preirradiation surgical cytoreduction of the tumor was done in 41 dogs. Fifty dogs were irradiated by use of 10 fractions over 22 days, and 17 dogs were given a similar total dose in 5 fractions over 35 days. The
We present the case of a child who had had a previous episode of torsades de pointes (TdP) and who was scheduled for elective surgery under general anesthesia. The pathophysiology of this condition and the anesthesia concerns are discussed. An 8-year-old male with a history of osteogenic sarcoma had
Reaction of phosphoroorganic synthons with 8-azaadenine, 8-aza-2, 6-diaminopurine, and 8-azaguanine using cesium carbonate yielded regioisomeric 8-azapurine N7-, N8-, and N9-(2-(phosphonomethoxy)alkyl) derivatives. This reaction followed by deprotection afforded isomeric 2-(phosphonomethoxy)ethyl
Between 1972 and 1986, 37 patients with lower genital tract malignancies were treated with intracavitary or interstitial brachytherapy. Thirteen patients presented with clear cell adenocarcinoma, 14 patients with embryonal rhabdomyosarcoma, 6 patients with endodermal sinus tumor, 3 patients with
