Burn-injured patients - the preferably unheard.

BACKGROUND

Data on colorectal cancer (CRC) diagnosis to treatment interval (DTI), an index of quality assurance in high-income countries (HICs) is lacking in South Africa. This study aimed to determine DTIs and their impact on CRC survival in a South African cohort.

METHODS

Participants (n = 289) from the Colorectal Cancer in South Africa (CRCSA) cohort were identified for inclusion. The DTI was defined as the duration between the diagnosis and initial definitive treatment and categorised into approximate quartiles (Q1-4). The DTI quartiles were 0-14 days, 15-28 days, 29-70 days, and ≥ 71 days. Overall survival (OS) was illustrated using the Kaplan-Meier method and compared between DTI groups using Cox proportional hazards (PH) regression.

RESULTS

There was no significant impact of the DTI (as quartiles) on overall CRC survival. The median length of time between DTI in this cohort was 29 days. Significant associations were identified between the DTI and self-reported ethnicity (p-value = 0.025), the site of the malignancy (colon vs rectum) (p-value < 0.0001), multidisciplinary team (MDT) review (p-value = 0.015) and the initial treatment modality (p-value < 0.0001).

CONCLUSION

Prolonged DTIs did not significantly impact survival for those with CRC in the CRCSA cohort. Symptom to diagnosis time should be investigated as a determinant of survival.
