Thirteen dogs with malignant tumors of the nasal cavity were treated with a combination of slow release cisplatin and megavoltage radiation. Radiation was delivered on a Monday through Friday schedule using a 6 MV linear accelerator. The median total dose was 49.5 Gy (range 49.5-56 Gy). Cisplatin was given using an open-cell polylactic acid polymer, impregnated with the drug and implanted intramuscularly at a distant site, as a slow release delivery system (OPLA-Pt [THM Biomedical, Inc]). The median dose used was 60 mg/m2 (range 60-100 mg/m2). When combined with radiation, this delivery system caused no systemic drug toxicity, and a local tissue reaction was seen in only two dogs. Acute side effects to normal tissue from radiation were not enhanced, as measured by subjective assessment. When compared to a group of historical controls that received radiation without OPLA-Pt, the dogs that received combined radiation and cisplatin had longer overall survival times, with a median of 580 days. The control group had a median survival of 325 days. Previously reported median survival times for comparable megavoltage radiation treatment range from 6 to 13 months. Some dogs in both groups also received adjubant chemotherapy but this did not influence survival time. By multivariate analysis, only the use of OPLA-Pt was found to significantly influence survival, with a p value of p = 0.023. Mega-voltage radiation and slow release cisplatin appears to be a well tolerated combination that may favorably affect survival of dogs with nasal tumors.- PMID:

LUCY HAD NONE OF THIS STUFF. STILL IN REMISSION AT 20 MONTHS POST BIOPSY PROVEN DIAGNOSIS. I MAY CONSIDER IT IF SHE TURNS. THE HOLISTIC TREATMENT / ORTHOMOLECULAR METHODS (simply herbs or natural substances used for thousands of years) SURE SEEMS TO WORK.
