Stage of presentation and survival rates of head and neck cancer in Western Cape, South Africa.

BACKGROUND

The Western Cape province in South Africa has a high age-standardised mortality from cancer. Most literature reports significantly poorer access to healthcare, more advanced cancers and worse survival for rural and remote populations. This study investigates if significant disparities exist with regard to stage at presentation and overall survival of patients with head and neck cancer (HNC) between geographical areas within the Western Cape province in South Africa.

METHODS

A retrospective chart review was conducted on all patients managed at the Combined ENT & Head and Neck Oncology clinic at Groote Schuur from January 2010 to December 2014. Ethics approval was granted by the University of Cape Town Human Research Ethics Committee (HREC, 351-2017).

RESULTS

Although we observed no significant difference in TNM clinical stages or overall survival between metropolitan and remote patients, there were statistically and clinically significant differences in terms of both stages of HNC and overall survival between some individual metropolitan and remote areas. The remote area of Eden had a median overall survival of more than 6 months less than that of the Southern subdistrict of the City of Cape Town.

CONCLUSION

Differences in HNC stages and overall survivals between some subdistricts of the City of Cape Town and remote areas are not only statistically significant but also clinically relevant.

CONTRIBUTION

This article highlights the need to improve on diagnostic and referral pathways for management of patients with HNC in the Western Cape.
