目的 研究采用高能电子束照射治疗外阴癌的疗效。 方法 ２０ 例外阴癌中初治组８ 例，局部病灶照射总量为６０ ～６５ Ｇｙ／５～６ 周，腹股沟区照射４０ Ｇｙ／４ ～５ 周。术后复发组７ 例，局部病灶照射总量６０ ～６５ Ｇｙ／５ ～６周。术后肿瘤残留补充放疗组５ 例，局部照射３０ ～４０ Ｇｙ／３ ～４ 周。 结果 照射后肿瘤全部消退占７３３３ ％ （ 不包括术后补充放疗组在内），皮肤反应较６０Ｃｏ 为轻，三年生存率为６１５％ 。 结论 有手术禁忌证者，较表浅的肿瘤，术后切缘有癌，术后复发者均可采用放疗，如并用以顺铂为主的化疗可提高疗效。
Objective To study the effect of high-energy electron beam irradiation on vulvar cancer. Methods Eighteen cases of neoplasm in the initial treatment group were included in the 8 cases. The total focal irradiation was 60 to 65 Gy/5 to 6 weeks, and the inguinal region was irradiated 40 Gy/4 to 5 weeks. The recurrence group had 7 cases and the total focal irradiation was 60-65 Gy/5 to 6 weeks. Postoperative tumor residual radiotherapy group 5 cases, local irradiation 30 ~ 40 Gy / 3 to 4 weeks. Results After irradiation, the total tumor regression accounted for 73% 33% (excluding the postoperative supplemental radiotherapy group). The skin reaction was lighter than that of 60Co. The three-year survival rate was 61.5%. Conclusions There are surgical contraindications, superficial tumors, postoperative margins, and postoperative recurrences can be treated with radiotherapy. For example, cisplatin-based chemotherapy can improve the efficacy.
