Traditional treatment options for esophageal cancer have centered on the triad of surgery, chemotherapy, and radiotherapy. Although surgery remains the gold standard for operable disease, photodynamic therapy (PDT) is emerging as a valid minimally invasive option for select patients with inoperable disease. Years of experience with PDT for esophageal cancer seem to suggest that it may be particularly useful for treatment of early unresectable lesions, palliation of locally advanced disease, and salvage therapy for stent blockage or local tumor recurrence. Further investigation into the ideal role for PDT, perhaps through a comparative study with other nonsurgical options, may help clarify where it fits in the treatment armamentarium for esophageal cancer.
