| contents | This study investigates the incidence and age at diagnosis of Non-Hodgkin Lymphoma (NHL) among missileers stationed at Malmstrom Air Force Base (MAFB) compared to national benchmarks. The analysis was motivated by reports of elevated cancer diagnoses within the Intercontinental Ballistic Missile (ICBM) community, specifically targeting NHL cases due to initial media focus and data collection through the Torchlight Initiative. The methodology integrates simulation-based estimation of expected diagnoses using incomplete data and expert knowledge on the underlying population. Statistical tests, including the Standardized Incidence Ratio (SIR) and a nonparametric Sign Test, were used to evaluate both the rate of diagnosis and age at diagnosis. The results demonstrate a statistically significant increase in NHL diagnoses among missileers in the later decades, with observed rates surpassing expected benchmarks. The study also finds that the median age of diagnosis is significantly younger for the study population compared to national averages. Key methodological contributions include estimating the population size and service start ages when comprehensive cohort data is unavailable, incorporating uncertainty quantification, and applying multiple hypothesis testing to identify temporal patterns. While the study acknowledges limitations such as small sample size and estimation uncertainty, as well as recognizing the study subjects as self-reported diagnoses, the findings highlight the effectiveness of these statistical techniques in identifying significant deviations from expected rates. Future studies should refine and build upon these methods, incorporating survival analysis and additional covariates to improve the robustness and scope of the results. |
