问：腹膜间皮瘤，患者男，53岁，部队转业干部，以前身体良好。此次病情：2007年7月发现腹膜上有很多小结节，大的有黄豆那么大，小的比绿豆还小，当时没有切除，也没有引起重视。2009年7·8月份开始腹水，10月份到泸州医学院附属医院肿瘤科化疗。
答：胸膜、腹膜间皮瘤属于恶性肿瘤，但是治愈率非常低，国外有资料显示术中光动力治疗，能够降低肿瘤复发率，明显延长患者生存期。如下是最新的资料：Malignant pleural mesothelioma is a deadly cancer, incurable and with a median survival 8 of approximately nine months. The best available chemotherapy, arguably the standardof care, only yields a 40% response rate and an 11 week extension in median survival.Surgery, the modality most likely to be associated with prolonged remission, remainsinvestigational and must always be combined with other modalities in an effort to treatthe microscopic disease that will remain after even the most aggressive operations. Onesuch modality, photodynamic therapy (PDT), is a light-based cancer treatment that hasfeatures making it particularly well suited as a component of a surgery-based multimodaltreatment plan. Utilizing intraoperative PDT has enabled development of a less drasticsurgical procedure that is also yielding some encouraging survival results. A uniqueaspect of photodynamic therapy is its stimulation of a tumor directed immune response, afeature that offers promise for designing future treatments.
