A 13-month-old Standardbred Colt had a recurrent hemangioma at the level of the coronary band. Multiple excisions had led to a nonhealing skin and hoof defect. Using 14 MV electrons, a total dose of 36 Gy was administered, given as six fractions of 6 Gy twice a week. Wound healing by second intention was achieved over the next 4 months and the colt began race training 6 months after the end of therapy. Twenty months later the colt is sound and there is no evidence of tumor recurrence. 相似文献

Local recurrence of feline soft tissue sarcomas is common despite aggressive treatment. Liposomal doxorubicin might serve as a depot radiosensitizer if administered concomitantly with daily radiotherapy and thus improve tumor control. In this pilot study, the feasibility of concomitant liposomal radiochemotherapy was evaluated in a palliative setting in 10 cats with advanced soft tissue sarcomas. Cats were treated with median number of 5 (range 5–7) daily fractions of radiotherapy and a median total dose of 20 Gy (range 20–31.5 Gy). One dose of liposomal doxorubicin was administered at the beginning of radiotherapy. Seven cats received further free or liposomal doxorubicin after completion of the liposomal doxorubicin/radiation protocol. Seven of the treated 10 cats (70%) achieved a partial (n=5) or complete (n=2) response with a median response duration of 237 days. The median progression free interval in all 10 cats was 117 days and the median overall survival time was 324 days. Concomitant liposomal radiochemotherapy was tolerated well in nine cats, one cat experienced temporary anorexia. Although the number of patients is too small to make definitive conclusions, results appear promising enough to investigate the role of liposomal doxorubicin as a radiosensitizer further. 相似文献

Prognostic significance of tumor histology and four computed tomography (CT) staging methods was tested retrospectively in dogs from three treatment centers that underwent intent-to-cure-radiotherapy for intranasal neoplasia. Disease-free and overall survival times were available for 94 dogs. A grouping of anaplastic, squamous cell, and undifferentiated carcinomas had a significantly shorter median disease-free survival (4.4 mo) than a grouping of all sarcomas (10.6 months). Disease-free survivals were not significantly different, when all carcinomas were compared with all sarcomas. The published original and modified WHO staging methods did not significantly relate to either survival endpoint. A modified human maxillary tumor staging system previously applied to canine nasal tumors was prognostically significant for both survival endpoints; a further modified version of that CT-based staging system resulted in improved significance for both survival endpoints. Dogs with unilateral intranasal involvement without bone destruction beyond the turbinates on CT, had longest median survival (23.4 months); CT evidence of cribriform plate involvement was associated with shortest median survival (6.7 months). Combining CT and histology statistically improved prognostic significance for both survival endpoints over the proposed CT staging method alone. Significance was lost when CT stages were collapsed to 相似文献
