Abstract
While numerous surveys of pattern of practices of palliative radiotherapy (RT) in advanced esophageal cancers have been published in developed countries, there is no such survey in African countries. During and after a regional training course by the International Atomic Energy Agency (IAEA) in palliative cancer care, a questionnaire was distributed to African RT centers to gather information about infrastructure and human resources available, and the pattern of practice of palliative RT for esophageal cancers. Twenty‐four of the 35 centers (60%) completed the questionnaire. Twenty out of 23 (87%) centers treat patients with esophageal cancer presenting with dysphagia using external beam RT (16 centers external beam RT alone and 4 centers also use brachytherapy as a boost). Twelve (60%) centers prescribe RT doses of 30 Gy in 10 fractions and 2 centers 20 Gy in 5 fractions. Eighteen centers (78%) have low dose rate (LDR) brachytherapy, and 9 (39%) centers have high dose rate (HDR) brachytherapy. One center only used HDR brachytherapy alone to a dose of 16 Gy in 2 fractions over 8 days. RT remains a major component of treatment of patients with esophageal cancers in African countries. Still, there is a great variety among centers in both indications for RT and its characteristics for a treatment indication.

During and after a regional training course by the International Atomic Energy Agency (IAEA) in palliative cancer care, a questionnaire was distributed to African RT centers to gather information about infrastructure and human resources available, and the pattern of practice of palliative RT for esophageal cancers. Twenty‐four of the 35 centers (60%) completed the questionnaire. Twenty out of 23 (87%) centers treat patients with esophageal cancer presenting with dysphagia using external beam RT (16 centers external beam RT alone and 4 centers also use brachytherapy as a boost). Twelve (60%) centers prescribe RT doses of 30 Gy in 10 fractions and 2 centers 20 Gy in 5 fractions. Eighteen centers (78%) have low dose rate (LDR) brachytherapy, and 9 (39%) centers have high dose rate (HDR) brachytherapy. One center only used HDR brachytherapy alone to a dose of 16 Gy in 2 fractions over 8 days. RT remains a major component of treatment of patients with esophageal cancers in African countries. Still, there is a great variety among centers in both indications for RT and its characteristics for a treatment indication.</p></abstract></abstractGroup></contentMeta><noteGroup><note xml:id="fn1" numbered="no"><p>This paper was presented as a poster at the 11th World Congress of the Diseases of Esophagus at Budapest, Hungary, in September 2008.</p></note></noteGroup></header></component></istex:document></istex:metadataXml><mods version="3.6"><titleInfo lang="en"><title>Palliative radiation therapy practice for advanced esophageal carcinoma in Africa</title></titleInfo><titleInfo type="abbreviated" lang="en"><title>Advanced esophageal carcinoma in Africa</title></titleInfo><titleInfo type="alternative" contentType="CDATA" lang="en"><title>Palliative radiation therapy practice for advanced esophageal carcinoma in Africa</title></titleInfo><name type="personal"><namePart type="given">V.</namePart><namePart type="family">Sharma</namePart><affiliation>Johannesburg Hospital, University of Witwatersrand, Johannesburg, South Africa;</affiliation><description>Correspondence: Vinay Sharma, MD, PhD, Johannesburg Hospital, University of Witwatersrand, Johannesburg 2193, South Africa.
