恶性肿瘤治疗的成败关键在于早期发现、早期诊断及早期治疗.化疗是肿瘤综合治疗中处于主导地位的治疗手段之一,贯彻于抗肿瘤治疗的始终.对防止病变复发、转移、提高患者的生存质量及延长生存期起着十分重要的作用.化疗药物系细胞毒制剂,不仅杀伤肿瘤细胞,对人体重要脏器(肝、肾、骨髓、心及肺等)也有损害.因此,在治疗过程中一些患者每因有关脏器功能异常而使临床医师裹足不前,不敢贸然进行化疗,但是经过认真检查及分析判断,上述有关脏器功能异常,有时则系肿瘤的直接或间接影响而非化疗所致,医师如采取等待或观望态度,往往使患者失去治疗机会,进而肿瘤进展,病情恶化.上述现象在一些晚期患者中较为常见.临床工作发现,这类患者经过我们认真检查分析判断后,积极主动地给患者进行化疗,亦取得了较理想的效果,现举一些实例供参考. The key to success or failure in the treatment of malignant tumors lies in early detection, early diagnosis and early treatment. Chemotherapy is one of the dominant treatment methods in comprehensive cancer treatment. It is always implemented in anti-tumor therapy. It prevents the recurrence of disease, metastasis, and improves the survival of patients. Quality and prolonged survival play a very important role. Chemotherapy drugs are cytotoxic agents that not only kill tumor cells, but also damage vital organs (liver, kidney, bone marrow, heart and lungs, etc.). Therefore, during the course of treatment, In some patients, each clinician would not dare to undergo chemotherapy because of organ dysfunction. However, after careful examination and analysis, the above-mentioned abnormalities in organ function are sometimes caused by direct or indirect effects of the tumor rather than chemotherapy. Physicians such as taking a wait or wait-and-see attitude often make patients lose treatment opportunities, and then the progress of the tumor, the disease deteriorated. The above phenomenon is more common in some advanced patients. Clinical work found that such patients after our careful examination analysis and judgment, proactive Chemotherapy to patients has also achieved satisfactory results. Now give some examples for reference.
