To determine the recent incidence of melanoma in the Nelson-Marlborough area of New Zealand and to compare this with a formerly determined incidence from the same area and with published incidences and trends elsewhere in New Zealand and Queensland.
All histopathology reports for the region were examined retrospectively each four weeks and relevant information extracted. In cases of doubt, pathologists were consulted and cases reviewed. Population, demographic and weather information was obtained from statistical records.
These showed a doubling of the incidence since the previous survey with a reduction in female incidence. There was marked reduction in the incidence in the age groups 20-39 with an increase in those over 60 years. The number of superficial more easily cured lesions were almost doubled with marked reduction in the more sinister thicker and nodular lesions.
The incidence of melanoma in the region is increasing at a rate comparable with other areas but with significant reductions in the incidence of thicker and more advanced melanoma as well as a decreased incidence in those under 40 years of age. The incidence in Nelson-Marlborough still remains very high but is slightly less than that shown for the Tauranga district over a similar period.
确定新西兰尼尔森 - 马尔堡地区黑色素瘤的近期发病率，并将其与该地区先前确定的发病率以及新西兰其他地区和昆士兰公布的发病率及趋势进行比较。
每四周回顾性检查该地区所有组织病理学报告，并提取相关信息。如有疑问，咨询病理学家并复查病例。人口、人口统计学和天气信息从统计记录中获取。
这些结果显示，自上次调查以来发病率翻了一番，女性发病率有所下降。20 - 39岁年龄组的发病率显著降低，60岁以上人群的发病率有所增加。浅表性更容易治愈的病变数量几乎翻倍，而更凶险的较厚和结节性病变数量显著减少。
该地区黑色素瘤的发病率增长速度与其他地区相当，但较厚和更晚期黑色素瘤的发病率显著降低，40岁以下人群的发病率也有所下降。尼尔森 - 马尔堡地区的发病率仍然很高，但略低于同期陶朗加地区的发病率。
