Sonodynamic therapy-assisted immunotherapy: A novel modality for cancer treatment.

Sonodynamic therapy (SDT), which is based on photodynamic therapy (PDT), is a new cancer treatment modality. Unlike PDT, which has poor tissue penetration, ultrasound can penetrate deeply into tissues and largely target tumor tissue to mediate the cytotoxicity of sonosensitizers. We hypothesize that, similar to PDT, SDT may perform effectively as a cancer vaccine.

Retrospective analysis of therapeutic effect and prognostic factors on early glottic carcinoma.

Objective: To investigate the therapeutic effect of surgery, radiotherapy and photodynamic therapy on early glottic carcinoma and prognostic factors.

Methods: Retrospective analysis of 202 cases with early glottic carcinoma (Tis-T2N0M0) underwent surgery (n=152), radiotherapy (n=20) and PDT (n=30) from 2000 to 2013 The KPS score, the disease-free survival (DFS), overall survival (OS), local control (LC), larynx preservation rate, laryngeal function were evaluated. The methods of χ (2)test or Fisher's exact probability method, Kaplan Meier method, log-rank test of Kaplan-Meier method, Cox proportional hazards model were used to analyze the data.
