由于方法学的差异,有关分裂症中癌症的发病率和死亡率研究结果极不一致。而且精神分裂症同时患有癌症较罕见,故获得两者关系的可靠结论实为困难。最近,丹麦一次调查表明精神分裂症病人中某些癌症的发病率较低。该组病人来自住院治疗这一特殊生活环境。故对评价医院环境对癌症发病的影响提供了观察的机会。为了澄清环境因素和精神分裂症本身对罹患癌症危险的作用,对有无癌症的两组精神分裂症患者进行了对照研究。方法:选择性别、年龄相匹配的有无癌症的两组精神分裂症住院病人。癌症分为:男性为肺癌和膀胱癌;女性为乳腺癌和子宫颈癌。调查因素包括:婚状状况、住所、职业、生育史、首次住院年龄、住院时间等。
Due to methodological differences, the findings on the incidence and mortality of cancer in schizophrenia are extremely inconsistent. Moreover, while schizophrenia has both rare cancers, it is difficult to get a reliable conclusion about the relationship between the two. Recently, a Danish survey showed that some cancers in schizophrenia patients have a low incidence. This group of patients comes from inpatient treatment of this special living environment. Therefore, the evaluation of the impact of hospital environment on the incidence of cancer provides an opportunity to observe. To clarify the role of environmental factors and schizophrenia itself in the risk of cancer, two groups of schizophrenic patients with and without cancer were compared. METHODS: Two groups of schizophrenic inpatients with sex and age matched for cancer were selected. Cancer is divided into: men are lung and bladder cancer; women are breast and cervical cancer. Survey factors include: marital status, domicile, occupation, birth history, first hospitalization, hospitalization time and so on.
