Long-term complete response in stage IVa esophageal squamous cell carcinoma treated with chemoradiotherapy and modulated electro-hyperthermia: A case report

Figure 5 Follow-up endoscopy and imaging after treatment completion. Endoscopic and radiological follow-up after multimodal treatment. A: Endoscopic view at approximately 2.2 months post-chemoradiotherapy showed a healing ulcer without evidence of residual tumor; B: Follow-up endoscopy at 58 months post-chemoradiotherapy revealed no signs of local recurrence; C: Follow-up computed tomography scan at approximately 2.5 months post-chemoradiotherapy, showing significant tumor regression and resolution of pneumonia; D: Follow-up computed tomography scan at 60 months (5 years) post-chemoradiotherapy, confirming a sustained complete response and progression-free status.
