治疗睾丸肿瘤的一般程序是:先切除睾丸,而后根据组织学类型、瘤标以及淋巴结和远处转移情况进行放疗、化疗或淋巴结清扫术。我院收治的睾丸精原细胞瘤中,有两例因瘤体较大采用N-甲酰溶肉瘤素(以下简称氮甲)先减细胞化疗行术前准备。待肿瘤明显缩小后,再行切除,可取得较好疗效,现报告如下: 例1:男、36岁、农民。自幼右阴囊内无睾丸,有时右腹股沟可扪及未下降之睾丸。因下腹偏右生长一儿头大小之肿块于1981年7月15日入院。入院后以“膀胱肿瘤”而取下腹正中切口探查。术中见膀胱右后壁外有一直径约15cm的肿物,与右精索相连,认定为右侧隐睾恶变。肿瘤与周 The general procedure for the treatment of testicular tumors is to remove the testis first, and then to perform radiotherapy, chemotherapy or lymph node dissection according to histological type, tumor markers, lymph node and distant metastasis. Of the testicular seminoma tumors treated in our hospital, there were two cases because of the larger size of the tumor using N-formyllysin sarcoma (hereinafter referred to as N-A) prior to preoperative chemotherapy. After the tumor is significantly reduced, re-excision can achieve better results. The current report is as follows: Example 1: Male, 36 years old, farmer. There is no testis in the right scrotum since childhood, and sometimes the right groin can lick and drop the testis. A child with a head-sized mass was admitted to the hospital on July 15, 1981. After hospital admission, a ventral midline incision was taken with a “bladder tumour.” During the operation, there was a tumor with a diameter of about 15 cm outside the right posterior wall of the bladder, which was connected with the right spermatic cord and was considered to be malignant of the right cryptorchidism.
