A proportionate mortality ratio (PMR) analysis utilizing death certificates and work histories was performed on 201 white male decedents who had been employed in pulp and paper production plants and had died between 1970 and 1984. PMRs for all malignant neoplasms (PMR = 131) and lung cancer (PMR = 151) were significantly elevated, whereas PMRs for lymphopoietic system cancer (PMR = 190) and cancer of the large intestine (PMR = 147) showed nonsignificant excesses. Most of the excess cancers of the lung and large intestine were limited to those with greater than 30 years between initial employment in a pulp and paper plant and death. Excess lung and lymphopoietic system cancers have been found in other studies of paperworker mortality, although this study failed to support previous findings of excess stomach cancer. These results continue to raise concerns that paperworkers are at elevated risk for some occupational cancers.
对201名曾受雇于纸浆和造纸厂且于1970年至1984年间死亡的白人男性死者进行了比例死亡率（PMR）分析，该分析利用了死亡证明和工作经历。所有恶性肿瘤的PMR（PMR = 131）和肺癌的PMR（PMR = 151）显著升高，而淋巴造血系统癌症的PMR（PMR = 190）和大肠癌的PMR（PMR = 147）显示出非显著的超额情况。大部分肺癌和大肠癌的超额情况仅限于那些在纸浆和造纸厂初次就业至死亡间隔超过30年的人。在其他造纸工人死亡率研究中也发现了肺癌和淋巴造血系统癌症的超额情况，尽管本研究未能支持先前关于胃癌超额的发现。这些结果继续引发人们对造纸工人患某些职业性癌症风险升高的担忧。
