Of cancer patients in Nigeria, 92% report at a late stage before treatment. Those with tumours of the head and neck region in particular, pose serious problems with management. Their advanced disease means that they are often inoperable and results of treatment by radiation are poor because the dose is limited to what the tissues can tolerate and also because the larger the tumour volume involved, the less the amount of radiation dose possible, so the response is poor. The problem is made worse by inadequate radiotherapy facilities. At the time of the study only one moderately equipped radiotherapy centre served the whole of Nigeria (with a population of 100 million) and neighbouring Ghana, Sierra-Leone and the Cameroons. There is usually a patient waiting list of about 3-4 months at any time, thus making prompt treatment impossible. These local problems and the search for an alternative approach led to this prospective study, which took place between 1980 and 1984. Two hundred and five adult patients with histologically proven, and locally advanced, epidermoid carcinoma in the head and neck region were given combination chemotherapy with Vincristine, Bleomycin and Methotrexate as the first line of management. There was a tumour regression rate of 68% (complete + partial), such that further treatment with surgery, radiotherapy, or a combination of both was then possible.
在尼日利亚的癌症患者中,92%在接受治疗前已处于晚期。尤其是那些患有头颈部肿瘤的患者,在治疗管理方面存在严重问题。他们的病情已发展到晚期,这意味着他们往往无法进行手术,而且放射治疗效果不佳,因为剂量被限制在组织所能耐受的范围内,同时,肿瘤体积越大,可能给予的放射剂量就越少,所以治疗反应较差。放疗设施不足使问题更加严重。在研究开展之时,整个尼日利亚(人口1亿)以及邻国加纳、塞拉利昂和喀麦隆仅有一个设备中等的放疗中心。任何时候通常都有大约3至4个月的患者候诊名单,因此无法及时进行治疗。这些当地存在的问题以及寻求替代治疗方法的需求促成了这项前瞻性研究,该研究于1980年至1984年期间进行。205例经组织学证实为头颈部局部晚期表皮样癌的成年患者,接受了以长春新碱、博来霉素和甲氨蝶呤联合化疗作为一线治疗方案。肿瘤消退率为68%(完全缓解 + 部分缓解),使得后续有可能采用手术、放疗或两者联合的进一步治疗。
