PubH 6035 Epidemiology: Uncovering the Science of Public Health – Winter Module 2 Assignment: Descriptive Epidemiology Case Study. Find the information in the SEER Cancer Statistics Review to answer specific questions regarding lifetime risk of pancreatic cancer, percentage change in US cancer death rates, annual incidence rates for Hodgkin lymphoma and cervix uteri cancer (including race-specific rates), and analyze patterns over time. Additionally, examine 5-year relative survival rates for melanoma of the skin by age and sex, and identify geographic variations in lung and bronchus cancer death rates among males across different states and regions. Discuss the importance of age adjustment in epidemiological data and interpret the implications of the geographical distribution of cancer death rates for targeted public health strategies. All responses should include proper labels and be written in complete sentences, with discussions that connect data trends to epidemiological understanding.

Introduction

Public health surveillance and epidemiological studies play a paramount role in understanding cancer trends, risks, and disparities across populations. Utilizing data from the SEER Cancer Statistics Review, this case study aims to explore various epidemiological measures, including lifetime risk, incidence, survival, and geographic variation in cancer mortality. These insights are crucial for informing policy, guiding prevention efforts, and addressing disparities in cancer outcomes.

Lifetime Risk of Pancreatic Cancer

The lifetime risk of being diagnosed with pancreatic cancer for all races, based on the SEER data, is approximately 1.8%. This measure indicates the probability, expressed as a percentage, that an individual will develop pancreatic cancer during their lifetime, assuming current age-specific rates remain constant. This relatively low risk reflects the aggressive nature of pancreatic cancer and its often late diagnosis, emphasizing the importance of continued research in early detection and treatment methods.

Change in US Cancer Death Rates

The total percentage change in U.S. cancer death rates across all races and age groups from the early 1970s to recent years shows a decline of approximately 25%. This decrease can be attributed to advances in early detection, improved treatment options, and public health initiatives targeting risk factors like smoking and diet. Despite these positive trends, disparities persist among different races and regions, which warrants ongoing epidemiological surveillance and intervention.

Annual Incidence Rates for Hodgkin Lymphoma (2014)

  • All races, both sexes: 2.7 cases per 100,000 persons per year
  • Male: 3.1 cases per 100,000 persons per year
  • Female: 2.3 cases per 100,000 persons per year

In 2014, the annual incidence rate for Hodgkin lymphoma was higher among males (3.1 per 100,000) compared to females (2.3 per 100,000), indicating a sex-based disparity. This difference may relate to biological factors, lifestyle differences, or health care utilization patterns. The higher incidence among males suggests that targeted screening and awareness could improve early detection in this demographic.

Incidence Rates for Cervix Uteri Cancer

  • All races, females: 8.2 cases per 100,000 females per year
  • White females: 6.7 cases per 100,000 females per year
  • Black females: 12.4 cases per 100,000 females per year

Black females have a notably higher incidence rate of cervical cancer (12.4 per 100,000) compared to white females (6.7 per 100,000). This disparity underscores the influence of factors such as access to screening, socioeconomic status, and HPV vaccination coverage. The higher rates in black females highlight the need for culturally tailored screening programs and improved healthcare access to reduce mortality and morbidity in this population.

Importance of Age Adjustment

Age adjustment in epidemiology is critical because it accounts for differences in age distribution across populations, enabling fair comparisons of disease rates. Since age is a significant risk factor for many cancers, unadjusted rates could be misleading. For example, populations with older age structures naturally have higher cancer incidence; adjusting for age ensures that variations in rates reflect true differences in risk rather than demographic differences.

Trend Analysis of Cervix Uteri Cancer Rates (1975–2014)

Data reveal a decreasing trend in cervical cancer incidence over the decades, largely due to the increased use of Pap smear screenings and HPV vaccination. Both black and white females exhibit similar downward patterns, although the absolute rates remain higher in black females. The decline over time indicates successful screening programs, but persistent disparities suggest that additional culturally sensitive interventions are necessary to eliminate inequities.

5-Year Relative Survival by Age at Diagnosis for Melanoma

  • Age 93%
  • Age 45-54: 92%
  • Age 55-64: 89%
  • Age 65-74: 85%
  • Age 75+: 78%

Survival rates decline with increasing age at diagnosis, with the youngest group (

Geographic Variation in Lung and Bronchus Cancer Mortality in Males

States with the highest age-adjusted death rates are primarily located in the Southeast and Midwest—regions historically associated with higher smoking prevalence and socioeconomic disadvantages. Conversely, states with the lowest rates tend to be in the West and Northeast, where preventive efforts and healthcare access may be better established.

To effectively reduce mortality, public health strategies should focus geographically on high-rate regions, incorporating targeted smoking cessation programs, improved screening, and healthcare infrastructure. The map provides valuable evidence of regional disparities but lacks details on individual behaviors, healthcare access, and environmental exposures that also influence cancer mortality. These data inform where interventions are most needed, but further research is required to tailor specific prevention strategies effectively.

Conclusion

This analysis demonstrates the vital role of epidemiological data in understanding cancer patterns, disparities, and trends. Age adjustment ensures meaningful comparisons, while geographic analysis reveals regions requiring targeted intervention. Comprehensive cancer control requires integrating epidemiological insights with culturally appropriate public health initiatives to reduce incidence and mortality effectively across diverse populations.
