June 4th, 2008. Malignant mesothelioma 2008

Novel therapies including intrapleural chemotherapy, photodynamic therapy and hyperthermic perfusion have also been used with some success. Finally there are several attempts at immunomodulating and targeted treatments, which are in phase I/II trials.

August 3rd, 2007. Polyhematoporphyrin-mediated photodynamic therapy and decortication in palliation of malignant pleural mesothelioma: a clinical pilot study

At 6-month follow up local tumor control and survival showed a significant difference in both groups. Although the study only includes a small number of patients not allowing definite conclusions, it indicates that the additional PDT/HBO represents a safe and technically feasible approach in the palliative setting of advanced malignant mesothelioma of the pleura.

June 15th, 2007. Effect of the TAT-RasGAP(317-326) peptide on apoptosis of human malignant mesothelioma cells and fibroblasts exposed to meso-tetra-hydroxyphenyl-chlorin and light

Conclusion: TAT-RasGAP317–326 selectively enhanced the effect of mTHPC and light delivery on H-meso-1 cells but not on fibroblasts. However, this effect was mTHPC dose-dependent and occurred only at a low sensitizer dose.

April 14th, 2007. Treatment of malignant pleural mesothelioma

As other treatment methods, chemohyperthermia, treatments using various kinds of cytokines and angiogenesis inhibitors, genetic treatment and photodynamic therapy have been attempted. The current treatment results for this disease are very poor, and there has been a strong demand for establishing an effective treatment method.

June 21st, 2006. Preclinical Comparison of mTHPC and Verteporfin for Intracavitary Photodynamic Therapy of Malignant Pleural Mesothelioma

Mediastinal organs were spared for both sensitizers but verteporfin resulted in a higher extent of tumour necrosis (80%) than mTHPC (50%). Drug dose escalation revealed a higher extent of PDT-related tumour necrosis for both sensitizers (mTHPC 55%, verteporfin 88%), however, verteporfin-PDT was associated with a higher toxicity than mTHPC-PDT.

May 23rd, 2006. Management of malignant mesothelioma by decortication and adjunct phototherapy

The survival curve was compared to that of 17 matched patients treated by decortication alone. Median survival increased from 250 to 440 days in the combined treatment group.

October 21st, 2005. Intraoperative photodynamic therapy of the chest cavity in malignant pleural mesothelioma bearing rats

Conclusions: PDT following pneumonectomy in mesothelioma bearing rats was technically feasible and allowed to study its effect on tumor and normal tissues. PDT-related tumor necrosis was observed after spherical and focal light delivery, however, pneumonectomy followed by PDT with spherical light delivery to the tumor-bearing chest cavity resulted in fatal complications.

July 1st, 2005. Photodynamic therapy as an adjunct to surgery for malignant pleural mesothelioma

Experimental work on MPM has shown that tumor selectivity of PDT depend on treatment conditions and can be improved by structural modification and improved targeting of the sensitizers. Refinements of PDT for mesothelioma will depend on a more detailed understanding of the pathways for preferential sensitizer accumulation within the tumor as well as on synergistic effects between PDT and chemotherapeutic agents.
