Abstract

In Asian countries, fast neutron therapy was first introduced at the National Institute of Radiological Sciences (NIRS), and followed by the Institute of Medical Science (IMS), Tokyo University, and Korea Cancer Center Hospital (KCCH). At NIRS, 2,129 patients were treated with d(30 MeV)+Be neutrons between 1975 and 1994. There were 274 patients referred for the treatment with P(50.5 MeV)+Be neutrons at KCCH during the period of 1986 through 1992. Unfortunately, fast neutron therapy performed at IMS was discontinued in 1991, where 458 patients had been treated with d(14 MeV)+Be neutrons since 1976. At NIRS, a vertical beam with multileaf collimator system was used for treatment of patients referred. The results showed that local control rates were 79% (19/24), 53% (14/26), and 89.3% (50/56) for carcinoma of the salivary gland, osteogenic sarcoma and carcinoma of the prostate, while complications for those were found to be 8.8, 8.3 and 17.8%, respectively. In the treatment of carcinoma of the lung, results were better for patients with adenocarcinoma than those with squamous cell carcinoma. Of 32 patients suffering from Pancoast tumor, 14 achieved local control, whereas 2 of 32 patients developed complications. On the other hand,...Continue Reading
