The use of photodynamic therapy (PDT) with porfimer is contraindicated for the treatment of esophageal cancer in patients with an existing bronchoesophageal or tracheoesophageal fistula. Prior to administration of PDT, patients must be evaluated by barium swallow to rule out fistulas, which can occur with PDT, particularly if the esophageal tumor is eroding into the trachea or bronchial tree.

Light should not be given directly to the variceal area because of the high risk of bleeding. In general, photodynamic therapy is not suitable for patients with esophageal or gastric varices, or patients with esophageal ulcers >1 cm in diameter.
