Advantages
- Relative selectivity and tissue speciality for tumor cells;
- Low toxicity, good safety, no immunosuppression and marrow inhibition;
- No bad effect on other therapies, complementary to surgery, radiotherapy and chemotherapy;
- Short treatment time;
- initiating therapeutic effectwithin 48-72 hours;
CLINICAL APPLICATION
Oral- pharygeal tumor
Early oral, nosal and nasopharygeal cancer: PDT had effective rates of 75%-100%.
Esophageal cancer
- PDT had radical effect for early esophageal cancer;
- PDT brings the five-year survival rate of 74%-84% in T1 and T2 stage of esophageal squamous and adenocarcinoma; PDT can effectively ameliorate obstruction of advanced esophageal carcinoma. Very effective for cervical esophageal cancer, Able to treat undermucosal disseminated and latent cancer. For cancer which grows into intracavity and stent has been placed, PDT can eradicate neoplasm in cavity.
Barrett esophagus
Normal squamous epithelium lining the esophagus is replaced by glandular columanar epithelium, that called Barrett esophagus, which increases the risk of esophageal adenocarcinoma. PDT not only can effectively eradicate Barrett epithelium, but has good result for early adenocarcinoma.
Lung cancer
- For lung cancer with bronchial obtruction, PDT induce improvement of air-way obstruction
