The medical records of 87 dogs treated with surgery for cutaneous malignant melanoma (CMM) of the haired skin were retrospectively reviewed for overall survival time (OST), progression-free survival time (PFS), and prognostic factors. The post-surgery median PFS and median OST were 1282 days and 1363 days, respectively. The post-surgery metastatic rate was 21.8% with a local recurrence rate of 8%. Increasing mitotic index (MI) was predictive of a significantly decreased OST and PFS on multivariable analysis [hazard ratio (HR): 1.05, 95% confidence interval (CI): 1.02 to 1.07 and HR: 1.04, 95% CI: 1.02 to 1.06, respectively]. Increasing age was likewise predictive of a significantly decreased OST and PFS on multivariable analysis (HR: 1.39, 95% CI: 1.17 to 1.65 and HR: 1.33, 95% CI: 1.14 to 1.54, respectively). These results confirm clinical impressions that long survival times are likely in dogs diagnosed with malignant melanoma of the haired skin when treated with surgery alone.
对87只接受手术治疗的有毛皮肤皮肤恶性黑色素瘤（CMM）犬的病历进行回顾性分析，以评估总生存时间（OST）、无进展生存时间（PFS）和预后因素。术后中位PFS和中位OST分别为1282天和1363天。术后转移率为21.8%，局部复发率为8%。多变量分析显示，有丝分裂指数（MI）增加预示着OST和PFS显著降低[风险比（HR）：1.05，95%置信区间（CI）：1.02至1.07；HR：1.04，95%CI：1.02至1.06]。多变量分析同样显示，年龄增加预示着OST和PFS显著降低（HR：1.39，95%CI：1.17至1.65；HR：1.33，95%CI：1.14至1.54）。这些结果证实了临床印象，即仅接受手术治疗的被诊断为有毛皮肤恶性黑色素瘤的犬可能有较长的生存时间。
