“…From 422 unique studies identified using the search strategy, 15 studies met the inclusion criteria (13)(14)(15)(16)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34). One population-based case-control study by Campbell and colleagues, using the Canadian National Enhanced Cancer Surveillance Study, reported and analyzed data from Ontario and seven other Canadian provinces separately using different physical activity measurement modality, and hence, these were analyzed as two separate studies (25).…”

“…On restricting analysis to six high-quality studies (13,14,16,30,32,33), physical activity continued to have a significant inverse association with gastric cancer risk (OR ¼ 0.86; 95% CI, 0.75-0.99), with moderate heterogeneity (I 2 ¼ 51%, Cochran Q test P ¼ 0.07). After excluding two studies in which the control population was composed of patients with nongastric cancer, a stable association was persistent between physical activity and gastric cancer (14 studies; 0.78; 95% CI, 0.71-0.87; refs.…”

“…The earliest cohort study recruited patients starting in 1965 and latest completed recruitment in 2000, with mean reported follow-up ranging from 6 to 18.8 years (13,14,16,29,30,32,33). Five studies were performed in Asian populations (16,26,27,31,32) and 10 studies were performed in Western populations (six in North America; refs. 13,15,25,28,33,34) and 4 in Europe) (14,24,29,30).…”

“…Six studies were performed exclusively in men (27, 28, 30, 32-34); in one case-control study from Turkey (26), no cases of gastric cancer were observed in females, who formed <10% of entire study population. In eight studies, recreational (with or without household) physical activity was the only measured domain (13,24,25,27,(29)(30)(31)(32); in three studies, only occupational physical activity was inferred on the basis of the job title (15,26,34); four other studies reported combined recreational and occupational activity in estimating the lifetime physical activity (14,16,28,33). In four studies, cases and controls were recruited from hospitals (24,26,27,31); one study obtained data on cases and controls exclusively based on the state cancer registry, with no direct patient contact (34).…”

Physical activity may be associated with reduced risk of gastric cancer. We performed a systematic review and meta-analysis to evaluate the magnitude of the association and the quality of supporting evidence. After a comprehensive search of bibliographic databases and conference proceedings through February 2013 for observational studies that examined associations between recreational and/or occupational physical activity and gastric cancer risk, we identified 16 studies (seven cohort, nine case control) reporting 11,111 cases of gastric cancer among 1,606,760 patients. Summary adjusted-OR estimates with 95% confidence intervals (CI) were estimated using the random-effects model. Meta-analysis demonstrated that the risk of gastric cancer was 21% lower among the most physically active people as compared with the least physically active people (OR ¼ 0.79; 95% CI, 0.71-0.87) with moderate heterogeneity among studies (I 2 ¼ 55%). This protective effect was seen for gastric cancers in the cardia (four studies; OR ¼ 0.80; 95% CI, 0.63-1.00) and distal stomach (five studies; OR ¼ 0.63; 95% CI, 0.52-0.76). The effect size was significantly smaller in highquality studies (six studies; OR ¼ 0.86; 95% CI, 0.75-0.99), as compared with low-quality studies (10 studies; OR ¼ 0.74; 95% CI, 0.69-0.81). The results were consistent across sex, study quality, study design, and geographic location. In conclusion, meta-analysis of published observational studies indicates that physical activity is associated with reduced risk of gastric cancer. Lifestyle interventions focusing on increasing physical activity may decrease the global burden of gastric cancer, in addition to a myriad of other health benefits. Cancer Prev Res; 7(1); 12-22.

Physical activity across the lifespan and liver cancer incidence in the NIH‐AARP Diet and Health Study cohort

et al. 2018

While liver cancer rates in the United States are increasing, 5‐year survival is only 17.6%, underscoring the importance of prevention. Physical activity has been associated with lower risk of developing liver cancer, but most studies assess physical activity only at a single point in time, often in midlife. We utilized physical activity data from 296,661 men and women in the NIH‐AARP Diet and Health Study cohort to test whether physical activity patterns over the life course could elucidate the importance of timing of physical activity on liver cancer risk. We used group modeling of longitudinal data to create physical activity trajectories using four time points across the life course from teenage years through middle age, identifying seven distinct trajectories. We then used Cox proportional hazards regression to assess the association between the physical activity trajectories and risk of hepatocellular carcinoma, the most common type of liver cancer. We found that, in adjusted analyses, compared to those with consistently low physical activity patterns, those who maintained activity levels over time had a 26–36% lower risk of liver cancer and those who increased physical activity over time had no associations with risk, while those who decreased activity over time had a nonsignificantly higher risk of liver cancer. Our results suggest that sustained physical activity is associated with lower risk of hepatocellular carcinoma, while increasing physical activity later in life may not yield the same benefit. Future research with larger sample sizes and more detailed data on dose and timing of physical activity may continue to yield insight into this association between physical activity and liver cancer risk.

Numerous epidemiological studies have examined the association between physical activity and pancreatic cancer; however, findings from individual cohorts have largely not corroborated a protective effect. Among other plausible mechanisms, physical activity may reduce abdominal fat depots inducing metabolic improvements in glucose tolerance and insulin sensitivity, thereby potentially attenuating pancreatic cancer risk. We performed a systematic review to examine associations between physical activity and pancreatic cancer. Six electronic databases were searched from their inception through July 2009, including MEDLINE and EMBASE, seeking observational studies examining any physical activity measure with pancreatic cancer incidence/mortality as an outcome. A random effects model was used to pool individual effect estimates evaluating highest vs. lowest categories of activity. Twenty-eight studies were included. Pooled estimates indicated a reduction in pancreatic cancer risk with higher levels of total (five prospective studies, RR: 0.72, 95% CI: 0.52-0.99) and occupational activity (four prospective studies, RR: 0.75, 95% CI: 0.59-0.96). Nonsignificant inverse associations were seen between risks and recreational and transport physical activity. When examining exercise intensity, moderate activity appeared more protective (RR: 0.79, 95% CI: 0.52-1.20) than vigorous activity (RR: 0.97, 95% CI: 0.85-1.11), but results were not statistically significant and the former activity variable incorporated marked heterogeneity. Despite indications of an inverse relationship with higher levels of work and total activity, there was little evidence of such associations with recreational and other activity exposures.Pancreas cancer is the thirteenth most common malignancy in Europe but is the fifth most frequent cause of cancer death. 1 Although relatively rare it grows aggressively, it metastasises early and is often detected late; consequently, 5 year survival is formidably low at only 5% in Europe and 75% of patients die within a year of their initial diagnosis. 2 Current pharmacological and radiological modalities confer little benefit to this neoplasm; a focus on methods for both its prevention and earlier detection are therefore pivotal. Despite this dismal prognosis, the etiology of pancreatic cancer remains poorly understood. Cigarette smoking is the most strongly associated risk factor for this disease; a meta-analysis of 82 articles (42 retrospective and 40 prospective studies) has shown that smoking may increase the risk of this neoplasm by as much as 75% (RR: 1.74, 95% CI: 1.61-1.87). 3 In addition, long-standing type II diabetes 4,5 and obesity 6-8 have also been associated with this multifaceted disease. Despite the potential for physical activity to ameliorate the effect of these latter risk factors, findings from observational epidemiological studies examining physical activity and pancreatic cancer risk remain ambiguous. 9,10 Physical inactivity and obesity, particularly abdominal adiposity, increase the risk ...
