RESUMO
Objective To investigate the short-term clinical effect of CT guided 125Ⅰ radioactive particle therapy in superficial malignant tumor. Methods The clinic data of 28 patients with metastatic superficial malignant tumor in our hospital were analyzed retrospectively.All patients were treated with CT guided 125Ⅰ radioactive particle therapy.The short-term effects,1 year survival rate and 1 year progression free survival rate of the patients were compared.Results Objective remission rate(ORR)and disease control rate(DCR)after 6 months were 92.86% and 100.00%.1 year overall survival and 1 year progression free survival were 96.43%(27/28)and 82.14%(23/28), respectively.The median overall survival and median progression free survival were 26.978 months (95%CI:22.558-31.399)and 16.932 months (95 % CI:14 .471-19.393).There were 27 cases of 0-Ⅱ degree adverse reactions,1 case of grade Ⅲ adverse reactions and no grade Ⅳ adverse reactions.No signs of 125Ⅰ radioactive particle translocation,vascular embolism and vascular rupture were found. Conclusion 125Ⅰ radioactive particle treatment of superficial malignant tumor has a definite short-term curative effect,with overall survival and progression free survival longer and higher safety,which can be considered in clinical application.
RESUMO
In Palliative care, we meet patients with easy-bleeding superficial malignant tumors, such as head and neck cancer, skin metastasis of all kinds of cancer and unresectable breast cancer. But it is not easy to control bleeding even though we use various means, and many doctors have difficulties in stopping bleeding. We report a case with a recurrent tumor of pharyngeal cancer that showed easy-bleeding and discharged massive exudates. Although she received several alcohol local injections because of bleeding of the tumor, she needed a dressing change over 5 times in a day. It made her QOL worse. In this case, we used Mohs paste and after using it, the surface had been fixed and dried up, resulting in a decrease in bleeding, exudate, frequency of dressing change and bad odor. Mohs paste was made of distilled water, zinc chloride, zinc starch and Glycerol. Zinc chloride changes to zinc ion by water in the wound and makes protein cohere and thereafter tissues, vessels and cell membrane of bacteria are fixed chemically. We could stop bleeding for 15 days with only 20 minutes contact with Mohs paste, and massive exudates and bad odor decreased. Mohs paste, which is made in your hospital pharmacy with cheap materials, can be used for bleeding or massive exudates repeatedly if there is not a thick blood vessel anatomically under the tumor. It was effective to improve her QOL. Palliat Care Res 2009; 4(2): 346-350
