Laser therapy and BICAP tumor probe therapy offer effective and safe means of palliating obstructive esophageal cancer. Future developments may allow more precise application of these techniques, based on more sensitive means of identifying abnormal tumor tissue. The development of endoscopic ultrasonography and the use of tissue sensitizing agents (such as hematoporphyrin derivatives) may allow more accurate means of differentiating normal from abnormal tissue. This may lead to more precise and extensive tumor destruction, less injury to normal tissue, and less potential for complication. As the use of both of these modalities becomes more widespread, their role in the treatment of esophageal cancer will continue to grow.
激光疗法和BICAP肿瘤探头疗法为缓解梗阻性食管癌提供了有效且安全的手段。未来的发展可能会基于更敏感的异常肿瘤组织识别方法，使这些技术的应用更加精确。内镜超声检查的发展以及组织致敏剂（如血卟啉衍生物）的使用，可能会带来更准确的区分正常组织与异常组织的方法。这可能会导致更精确、更广泛的肿瘤破坏，对正常组织的损伤更小，并发症的可能性更低。随着这两种治疗方式的使用越来越广泛，它们在食管癌治疗中的作用将持续增强。
