Abstract

OBJECTIVE

To determine outcome of cats with nonlymphoid tumors of the vertebral canal that undergo surgery.

DESIGN

Retrospective study.

ANIMALS

11 cats.

PROCEDURE

Information obtained from the medical records included signalment, tumor location, gross evaluation of completeness of surgical excision, histologic diagnosis, and survival time.

RESULTS

Median age of cats was 12 years: all cats had negative FeLV and feline immunodeficiency virus test results. All cats underwent a hemilaminectomy or dorsal laminectomy. The tumor was located in the thoracic portion of the vertebral column in 6 cats. Six cats had intradural-extramedullary tumors. Tumors included meningioma (n = 5), malignant nerve sheath tumors (2), and meningeal sarcoma, chondrosarcoma, lipoma, and osteosarcoma (1 each). One cat was lost to follow-up, 1 cat with meningioma was alive 1,400 days after surgery, and 1 cat with a nerve sheath tumor was alive 2,190 days after surgery. Median survival time for the other 4 cats with meningioma was 180 days (range, 30 to 600 days).

CLINICAL IMPLICATIONS

Cats with nonlymphoid vertebral canal tumors that undergo surgery may have a good prognosis.

摘要

目的

确定接受手术治疗的患有椎管非淋巴样肿瘤的猫的预后情况。

设计

回顾性研究。

动物

11只猫。

过程

从病历中获取的信息包括特征、肿瘤位置、手术切除完整性的大体评估、组织学诊断和生存时间。

结果

猫的中位年龄为12岁：所有猫的猫白血病病毒和猫免疫缺陷病毒检测结果均为阴性。所有猫均接受了半椎板切除术或背侧椎板切除术。6只猫的肿瘤位于脊柱胸段。6只猫患有硬膜内髓外肿瘤。肿瘤包括脑膜瘤（n = 5）、恶性神经鞘瘤（2只）、脑膜肉瘤、软骨肉瘤、脂肪瘤和骨肉瘤（各1只）。1只猫失访，1只患有脑膜瘤的猫术后存活1400天，1只患有神经鞘瘤的猫术后存活2190天。其他4只患有脑膜瘤的猫的中位生存时间为180天（范围为30至600天）。
