Results 42 cases were classified into conventional, fibrosarcoma lesion, myxoid and melanin pigmented DFSP.

Conclusions A slowly enlarged painless cutaneous or subcutaneous nodules quickly growing in recent time is the clinical characteristic feature of DFSP.

结论皮内或皮下缓慢生长的无痛性小结节于近期生长加快为该病的临床特征；

Once the tumor is diagnosed as DFSP after local excision, it is necessary to take wide excision.

在局部切除术后，一经病理检查确诊为DFSP，必须施行补充广泛切除以避免肿瘤残留；

Results DFSP, with low malignancy, slow growth, rare metastasis, was easy to relapse.

结果该肿瘤属低度恶性，生长缓慢，很少转移，但易复发；

Radiotherapy can not reduce the recurrence rate of DFSP in the patients only receiving local resection.

放射治疗不能降低局部复发率。

CD34 is positive and very characteristic for diagnosis and identification of DFSP.

CD34稳定阳性表达对隆突性皮肤纤维肉瘤的诊断及鉴别诊断有一定意义。

Methods The clinical and pathological data of 128 patients with DFSP treated at 81 Hospital of PLA from 1969 to 2001 were reviewed retrospectively.

方法1969～2001年我院共收治128例隆突性皮肤纤维肉瘤患者，对其临床和病理资料进行回顾性分析。

3-year disease-free survival rate ( DFSR) of the young and postmenopausal women with breast cance were 78.6%, 93.1% respectively, and significant difference was observed ( P < 0.05).

青年组与绝经组3年无病生存率（DFSR）分别为78.6%，93.1%，差异明显（P<0.05）。

The five-year survival rate ( SR), disease free survival rate ( DFSR) were 65 6% and 54 5%, respectively.

总的5年生存率、无瘤生存率分别为65.6%和54.5%。

At last, the DFST algorithm and the depth first search algorithm of the AI are compared and the differences between them are showed.

最后，将该算法与人工智能中的深度优先搜索算法[3]进行了比较，阐述了其中的不同之处。
