Extensive stage small cell lung cancer (ES-SCLC) and palliative care disparities: a national cancer database study

Literature on disparities in palliative care receipt among extensive stage small cell lung cancer (ES-SCLC) patients is scarce. The purpose of this study was to examine disparities in palliative care receipt among ES-SCLC patients.

Patients aged 40 years or older diagnosed with ES-SCLC between 2004 and 2015 in the National Cancer DataBase (NCDB) were eligible. Two palliative care variables were created: (1) no receipt of any palliative care and (2) no receipt of pain management-palliative care. The latter variable indicated pain management receipt among those who received any palliative care. Log binomial regression models were constructed to calculate risk ratios by covariates. Unadjusted and mutually adjusted models were created for both variables.

Among 83 175 patients, the risk of no palliative care receipt was higher among Blacks compared with Whites in unadjusted and adjusted models (both model HRs 1.02; 95% CIs 1.00 to 1.03, p<0.05). Patients older than 59 years were at a higher risk of not receiving palliative care than younger patients (HR 1.02; 95% CI 1.01 to 1.03 for 59-66, HR 1.04; 95% CI 1.03 to 1.05 for 66-74, HR 1.06; 95% CI 1.05 to 1.08 for >74). Among 19 931 patients, the risk of no pain management-palliative care was higher among black patients on unadjusted analysis (HR 1.02; 95% CI 1.00 to 1.03, p<0.05). Patients between 66 and 74 years were at a higher risk of not receiving pain management-palliative care than patients younger than 59 years (HR 1.02; 95% CI 1.00 to 1.03, p<0.05).

Significant disparities exist in palliative care receipt among ES-SCLC patients.
