We describe complication rates and outcomes, focusing on stricture rates following chemoradiotherapy and radiotherapy, for oesophageal squamous cell carcinoma.
Background
Definitive chemoradiation for oesophageal squamous cell carcinoma (SCC) is the first‐line treatment in many centres. However, it is not without morbidity. We assess outcomes for patients treated with definitive chemoradiotherapy and radiotherapy.
Methods
A retrospective review of a prospectively maintained database (Radiotherapy Department, Canterbury District Health Board) was undertaken. All patients who underwent definitive radiotherapy for oesophageal SCC between October 1996 and April 2015 were included.
Results
Sixty patients underwent chemoradiotherapy with curative intent and 17 underwent definitive radiotherapy with curative intent. Median age was 69 years (44–84 years) for those undergoing chemoradiotherapy and 73 years (36–85 years) for those who underwent definitive radiotherapy. Tumour location in all patients was upper third in 14 (18%), middle third in 39 (51%), lower third in 22 (29%) cases and junctional tumour in two (3%). Staging information was complete for 73 of 77 patients (stage I 16/77 (21%), stage II 40/77 (52%), stage III 17/77 (22%)). Median dose of external beam radiotherapy for those who underwent definitive chemotherapy was 50.4 Gy (30–63 Gy) and 60 Gy (50–64 Gy) for definitive radiotherapy. Median length of follow‐up was 39 months (range 4–120 months). Strictures developed in 58% of all patients (52% chemoradiotherapy and 76% definitive radiotherapy). Twenty‐four (32%) patients were dilated and 14 (18%) stented. The chemoradiotherapy group had higher 5‐year survival than definitive radiotherapy group (34% versus 6%, P = 0.0034).
Conclusion
Oesophageal SCC treated with chemoradiation has a 5‐year survival rate of 34%. Post‐treatment strictures occur in 52% of patients with chemoradiotherapy and 76% with definitive radiotherapy.
