在1965年1月～1987年7月间,在肯塔基大学医疗中心治疗了22例小的(<2cm)表浅层浸润(<5mm)的外阴鳞癌,并评价了淋巴结转移的预后因素,其中包括;浸润的深度,分级,淋巴浆细胞浸润(LPI)的程度,淋巴管间隙浸润的存在(LVSI)和神经周围的浸润(PNI)。病人平均年龄60岁(28～78岁)。用目镜测微计从上皮的表面测量侵犯的深度,平均深度2mm(0.7～4mm)。18例为Ⅰ级肿瘤,4例Ⅱ级。LPI 最轻的10例,中
Between January 1965 and July 1987, 22 patients with small (<2 cm) superficial infiltrates (<5 mm) of vulvar squamous cell carcinoma were treated at the University of Kentucky Medical Center and the prognostic factors of lymph node metastasis were evaluated, with Including depth of invasion, grading, degree of lymphoproliferation (LPI), presence of lymphatic space infiltration (LVSI), and perineural infiltration (PNI). The average patient age of 60 years (28 to 78 years old). The depth of invasion was measured from the surface of the epithelium with an eyepiece micrometer, with an average depth of 2 mm (0.7 to 4 mm). 18 cases of grade Ⅰ tumor, 4 cases of grade Ⅱ. The lightest LPI in 10 cases
