OBJECTIVE: To evaluate the relationship and strength of association for alcohol drinking and tea consumption with the riskS of nasopharynx cancer among Chinese population so as to provide control rationales for nasopharynx cancer in China.
METHODS: A systematic search of 3 Chinese electronic databases (CNKI, VIP, Wanfang) and 3 English databases (Pubmed, ScienceDirect and SpringerLink) up to March 2013 was performed. Two reviewers independently conducted the literature search, examined eligibility and performed data extraction and quality evaluations. Pooled odd ratio (OR) value and 95%CI value were calculated with random-effects model weighted with inverse of variances.
RESULTS: A total of 14 studies (including 3 cohort and 11 case-control) involving 6559 cases of nasopharynx cancer and 10 567 controls from 6 provinces were included. The pooled OR between alcohol drinking and risks of nasopharynx cancer was 1.12 (95%CI: 0.98-1.26; I(2) = 44.5%, P = 0.037). Compared with the non-drinkers, the risks of nasopharynx cancer for regular drinkers and occasional drinkers were 1.18 (95%CI: 1.00-1.38; I(2) = 0.0%, P = 0.578) and 0.76 (95%CI: 0.65-0.89; I(2) = 33.4%, P = 0.212). And the association of tea consumption with the risks of nasopharynx cancer was 0.53 (95%CI: 0.43-0.60; I(2) = 17.9%, P = 0.301).
CONCLUSIONS: In China, occasional alcohol drinking may decrease the risks of nasopharynx cancer while regular drinking elevates the risks. And there is significantly protective effect for tea consumption on the risks of nasopharynx cancer.
