Salvage Strategies in Esophageal Cancer Treatment

Salvage therapy for oesophageal cancer addresses locoregional persistence or recurrence following definitive chemoradiotherapy or radiotherapy. Approaches range from radical salvage oesophagectomy to less-invasive endoscopic techniques, re-irradiation and photodynamic therapy. Patient selection is guided by tumour location, depth of invasion, prior treatment toxicity and overall performance status. Recent advances in imaging, endoscopic equipment and radiotherapy planning have refined indications, improved local control and reduced morbidity. A multidisciplinary framework ensures that interventions are tailored to maximise survival benefit while preserving organ function and quality of life.

Research from Nature Portfolio

Recent studies have demonstrated the efficacy of endoscopic resection for local residual or recurrent oesophageal squamous cell carcinoma following definitive chemoradiotherapy or radiotherapy. A retrospective analysis of ninety-eight lesions treated over seven years identified key endoscopic and ultrasonographic parameters predictive of complete resection. Flat tumours on white-light endoscopy and preservation of the fifth ultrasound layer were associated with R0 resection rates in excess of 94 %, guiding patient selection for this minimally invasive approach. These findings underscore the importance of high-resolution imaging and tailored endoscopic techniques in optimising salvage outcomes.

The graph below shows the total number of articles in salvage strategies in esophageal cancer treatment across all publications each year (not limited to Nature Index journals).

Technical terms

Salvage therapy: Treatment administered after initial curative-intent therapy fails, aiming to eradicate residual or recurrent disease.

Chemoradiotherapy (CRT): Combined use of chemotherapy and radiotherapy to enhance tumour control.

Endoscopic resection (ER): Removal of superficial neoplastic lesions via endoscopy, including mucosal and submucosal dissections.

Photodynamic therapy (PDT): A light-activated treatment that induces tumour cell death following administration of a photosensitising agent.

R0 resection: Surgical or endoscopic removal of a tumour with histologically negative margins.

Endoscopic ultrasonography (EUS): High-frequency ultrasound probe used during endoscopy to assess tumour depth and adjacent structures.
