“…One study showed substantial variations of ICC stage distribution by birth region. 17 Immigrant women from East Asia, Western Europe and America had higher early-stage incidence whereas South Asian women had higher late-stage incidence. This study emphasizes that taking into account immigration history and birth region can identify important differences between population groups.…”

“…Generally, immigration history, visible minority status and being foreign-born are associated with lower participation rates of cervical cancer screening. 9,10,16,17,36,37 Canadian and US ICC incidence trends are closely tied to patterns of screening participation. 1,38 Risk factors for cervical cancer include smoking history and number of lifetime sexual partners.…”

“…Canadian studies report little variation in cervical cancer screening participation by levels of urbanization. 16,17,45 One study suggested rural residence was associated with lower screening rates. 11 Urban-rural variations may indicate differences in access to screening and diagnostic services, but also HPV prevalence, and sociodemographic and health characteristics.…”

“…Factors associated with lower access to screening services include lower educational attainment, lower socioeconomic status, not having a regular primary care provider, immigration history and identifying as Indigenous.

“…7 However, corresponding figures in HICs are different; in Canada, 34% of women have stage I disease and 19% of women have stage III and IV disease at diagnosis. 9 These differences in stage of cancer at diagnosis between India and HICs likely reflect differences in cancer awareness/education, availability of screening programs, and access to cancer care.…”

PURPOSE Lower socioeconomic status is associated with inferior cancer survival in high-income countries, but whether this applies to low- and middle-income countries is not well described. Here, we use a population-based cancer registry to explore the association between educational level and stage of cancer at diagnosis in South India. METHODS We used the Trivandrum District population-based cancer registry to identify all cases of breast and cervical cancer (women) and oral cavity (OC) and lung cancer (men) who were diagnosed from 2012 to 2014. Educational status—classified as illiterate/primary school, middle school, or secondary school or higher—was the primary exposure of interest. Primary outcome was the proportion of patients with advanced stage disease at diagnosis defined as stage III and IV (breast, cervix, or OC) or regional/metastatic (lung). RESULTS The study population included 4,547 patients with breast (n = 2,283), cervix (n = 481), OC (n = 797), and lung (n = 986) cancer. Educational status was 22%, 19%, and 26% for illiterate/primary, middle, and secondary school or higher, respectively. Educational status was missing for 33% of patients. The proportion of all patients with advanced stage disease was 37% (breast), 39% (cervix), 67% (OC), and 88% (lung). Patients with illiterate/primary school educational status were considerably more likely to have advanced breast cancer (50% v 39% v 36%; P < .001), cervix cancer (46% v 43% v 24%; P = .002), and OC cancer (77% v 76% v 59%; P < .001) compared with patients with higher educational levels. The proportion of patients with advanced lung cancer did not vary across educational levels (89% v 84% v 88%; P = .350). CONCLUSION A substantial proportion of patients in South India have advanced cancer at the time of diagnosis. This is particularly true among those with the lowest levels of education. Future health awareness and preventive interventions must target less-educated communities to reduce delays in seeking medical care for cancer.

Objective Prior evidence on the relative risk of cancer among people with psychotic disorders is equivocal. The objective of this study was to compare incidence and stage at diagnosis of cancer for people with psychotic disorders relative to the general population. Method We constructed a retrospective cohort of people with a first diagnosis of non‐affective psychotic disorder and a comparison group from the general population using linked health administrative databases in Ontario, Canada. The cohort was followed for incident diagnoses of cancer over a 25‐year period. We used Poisson and logistic regression models to compare cancer incidence and stage at diagnosis between people with psychotic disorders and the comparison group, adjusting for confounding factors. Results People with psychotic disorders had an 8.6% higher incidence (IRR = 1.09, 95%CI = 1.05,1.12) of cancer overall relative to the comparison group, with effect modification by sex and substantial variation across cancer sites. People with psychotic disorders also had 23% greater odds (OR = 1.23, 95%CI = 1.13,1.34) of being diagnosed with more advanced stage cancer relative to the comparison group. Conclusions We found evidence of elevated cancer incidence in people with non‐affective psychotic disorders relative to the general population. The higher odds of more advanced stage cancer diagnoses in people with psychotic disorders represents an opportunity to improve patient participation in recommended cancer screening, as well as timely access to services for cancer diagnosis and treatment. Future research should examine confounding effects of lifestyle factors and antipsychotic medications on the risk of developing cancer among people with psychotic disorders.
