本文介绍一例男性患者。经血管造影表明有右肾腺癌,胸部照片表明两肺已有癌转移。用 X 线照射原发性癌,约五个月后,作右肾切除术前,肺部转移癌已消退,且维持了约两年,亦即确诊为癌症后三年内,肺部转移消退的情况一直没有改变。临床上认为患者的癌肿已消退,可以正常地工作。本例进一步证实:用姑息疗法(包括 X 线照射)来治疗晚期的原发性肾癌,较以往对许多患者所采用的其他疗法,有更大的价值。近年来,有一些关于肿瘤“自然”消退的报导。有些是关于肾腺癌肺部转移病灶的消退。“自然”一词的意义应加以商讨,因所报导的大多数病例,是指癌的自然发展受外科治疗遏制。 This article describes a case of male patients. Angiographic angiography showed right renal adenocarcinoma, and chest photographs showed that both lungs had metastases. After X-rays were used to illuminate the primary cancer, about five months after the right nephrectomy, the lung metastases had subsided and remained for about two years. That is, within three years after the diagnosis of cancer, the metastasis of the lungs subsided. The situation has not changed. It is clinically considered that the patient’s cancer has subsided and can work normally. This case further confirms that the use of palliative therapy (including X-ray irradiation) to treat advanced primary kidney cancer is of greater value than other treatments used in many patients. In recent years, there have been reports of the “natural” regression of tumors. Some are related to the regression of renal adenocarcinoma lung metastases. The meaning of the word “natural” should be discussed, because the majority of reported cases meant that the natural development of cancer was curbed by surgical treatment.
