肾脏腺癌是一种较为罕见的癌。通常这种癌会迅速发展,临床症状迅速加剧。患者常见的临床表现要么是转移,要么是局部病灶太广泛而不能手术根治。化疗、激素治疗和许多免疫学上的处理,不影响患者的存活率。由于有一些在肾切除后出现罕见的自发性症状消退或全身性疾病消失的报告,现在已假定,免疫机制在控制这种肿瘤方面起着重要的作用。目前,尽管采用了多种治疗方法,但肾细胞癌(RCC)的自然史变化不大,故仍然是一种很难对付的疾病。
Kidney adenocarcinoma is a rare cancer. Usually this kind of cancer will develop rapidly and clinical symptoms will rapidly increase. The common clinical manifestations of patients are either metastasis or local lesions that are too extensive to be cured. Chemotherapy, hormone therapy, and many immunological treatments do not affect patient survival. Because there are reports of rare spontaneous regressions or disappearance of systemic diseases after nephrectomy, it has now been assumed that the immune mechanism plays an important role in controlling this type of tumor. At present, despite a variety of treatments, the natural history of renal cell carcinoma (RCC) has not changed so much, and it is still a very difficult disease to treat.
