Summary
Brief summary (as posted)
To evaluate the therapeutic efficacy and the safety for the treatments on malignant melanoma by combining semiantigen dinitrophenyl (DNP) in situ immunotherapy and laser therapy, and carry out monitoring on related immunological parameters of the patients. 72 patients with stage III (b or c) or stage IV skin (which could not be excised by operations) malignant melanoma were treated by combining simple semiantigen DNP in situ immunotherapy and laser therapy respectively. The changes in peripheral blood CD4+CD25+Treg regulatory T cells (Treg), CD8+T, CD4+ T effector cells, IL-10, TGF-β and other inhibitory cytokines of the patients were detected, the changes in anti-DNP IgG antibody titer was monitored, the relationship between delayed-type hypersensitivity (DTH) and survival was observed, and results of clinical follow-ups were also examined.

- description
- diluted dinitrophenyl(DNP) Vaseline (which equaled to 2% DNP 0.1ml) was started to be directly spread on the surfaces of primary or metastatic tumors of malignant melanoma patients since the first day of every circle of chemotherapy, simultaneously laser irradiation was carried out for 10 min, the power density of laser irradiation was 1W/cm2. The tumors were wrapped and blocked for two days to induce contact dermatitis. If lymph nodes had been cleared, sensibilization of 2×2cm was performed at occipital region. It was repeated once a week.
