Association between allergic rhinitis or hay fever and lung cancer

According to a recent study, an inverse association has been identified between allergic rhinitis (AR) and lung cancer. However, further epidemiological investigations are needed to fully assess the current landscape. The findings of this study were published in the journal, Medicine.

Following an extensive search of PubMed, ScienceDirect, and Google Scholar, a total of 7 suitable articles were incorporated into this systematic review and meta-analysis, with 4724 cases and 9059 controls, with 5 originating from the USA, and one each from Germany and Canada.

A strong inverse correlation between AR and lung cancer was seen in the pooled analysis, with an odds ratio of 0.55 (95% confidence interval: 0.45-0.68; P value < .00001).

The above study demonstrated a negative relationship between AR and lung cancer. However, additional epidemiological studies are required to comprehensively evaluate the present situation.
