一项刊登在国际杂志Cancer上的研究论文中，来自加州癌症预防学会的研究人员表示，结婚戒指或许是抵御癌症的强大药物，研究者在文章中指出，对于癌症而言，已婚人士似乎拥有显著的生存优势，相比已经结婚的男性患者而言，单身的男性癌症患者的死亡率要高于前者27%，而单身女性癌症患者的死亡率要高于已婚女性死亡率的19%。

　　文章作者Scarlett Lin Gomez说道，我们发现的这种效应非常显著，过去10至15年的研究结果表明，婚姻对于癌症患者也存在类似的效应，而这种效应总是因为已婚人士的配偶给予的支持和关爱。但已婚个体更趋向于有较高的混合性收入和更好的保险体系，为此研究人员决定进一步研究来揭示是否金钱在已婚配偶的生存率上扮演着重要角色。

　　研究人员分析了来自加州80万名个体的健康记录，这些个体在2000至2009年间均被诊断出患有侵袭性的癌症，而且研究者对这些个体一直追踪观察到2012年；研究者表示，财力状况对个体击败癌症的机会并不具有一定影响，反而来自配偶的关怀和支持是癌症患者获益且提高生存率的关键，比如带着他/她去定期进行检查，给对方准备一顿营养的餐食，并且提醒对方按时服药等。

　　已婚的癌症患者往往会从情感上的支持获益，而这会减少患者的压力并且改善患者疾病进展的步伐；Gregory Masters博士说道，致力于护理事业的价值或许对于改善癌症病人的生存率非常有必要，本文研究结果或许并不是仅对于改善癌症患者的生存有效，我们都知道不论疾病困扰，当两个人结为伴侣共同生活扶持，他们或许也会变得比较长寿。

　　研究者表示，结婚对个体生存的有益影响或许在各种族人群中都表现不同，白人或许会因结婚获益较多，而西班牙裔的美国人和太平洋岛居民或许获益较少，而出生在美国的西班牙裔的美国人和太平洋岛居民相比出生在国外的个体而言获益的程度又会增加。

　　BACKGROUND Although married cancerpatientshave more favorable survival than unmarried patients, reasons underlying this association are not fully understood. The authors evaluated the role of economic resources, including health insurance status and neighborhood socioeconomic status (nSES), in a large California cohort. METHODS From the California Cancer Registry, we identified 783,167 cancer patients (386,607 deaths) who were diagnosed during 2000 through 2009 with a first primary, invasive cancer of the 10 most common sites of cancer-related death for each sex and were followed through 2012. Age-stratified and stage-stratified Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs) for all-cause mortality associated with marital status, adjusted for cancer site, race/ethnicity, and treatment. RESULTS Compared with married patients, unmarried patients had an elevated risk of mortality that was higher among males (HR, 1.27; 95% CI, 1.26-1.29) than among females (HR, 1.19; 95% CI, 1.18-1.20; Pinteraction <.001). Adjustment for insurance status and nSES reduced the marital status HRs to 1.22 for males and 1.15 for females. There was some evidence of synergistic effects of marital status, insurance, and nSES, with relatively higher risks observed for unmarried status among those who were under-insured and living in high nSES areas compared with those who were under-insured and living in low nSES areas (Pinteraction = 6.8 × 10 9 among males and 8.2 × 10 8 among females). CONCLUSIONS The worse survival of unmarried than married cancer patients appears to be minimally explained by differences in economic resources.
