Here we report 3 cases of advanced cancer using multidisciplinary treatment including reibaisan (WTMCGEP, a dry extract of Wisteria floribunda, Trapa natans, Myristica fragrans, Coix semen, Ganoderma lucidum, Elfvingia applanata, Punica granatum). Case 1 : 87-year-old man, suffering from stage IV esophageal squamous cell carcinoma (ESCC) with aortic and bronchial invasion, was referred to our clinic for palliative care. He had radiotherapy and chemotherapy. Only one course of chemotherapy was performed due to its intolerable side effects. The treatment with reibaisan started 11 months after the diagnosis. ESCC disappeared after 17 months of reibaisan treatment, and no relapse was observed for 66 months after the diagnosis. Case 2 : 79-year-old man, suffering from stage III ESCC, was initially scheduled for surgery after preoperative chemotherapy. Only one course of preoperative chemotherapy was performed because of its intolerable side effects. Therefore, radiotherapy combined with reibaisan followed. ESCC disappeared 6 months later, and no relapse was observed for 33 months after the diagnosis. Case 3 : 73-year-old woman, suffering from stage IV pancreatic cancer with systemic metastasis (brain, lung, and peritoneum). She initially showed Trousseau syndrome and was treated with low-molecular-weight heparin for multiple cerebral infarctions. One-month palliative chemotherapy and reibaisan resulted in a rapid reduction of ascites and improvement of neurological symptoms. Her progression-free survival period was 7 months. She lived 13 months thereafter. This suggests that reibaisan, which contains crude drugs that have been shown to have antitumor effects, may be another promising treatment for advanced cancers.

We report a case of refractory transient ischemic attack (TIA) successfully treated with chotosan. A 64-year-old woman with recurrent right hemiparesis and dysarthria was seen in our clinic. Twenty-three months before coming to our clinic, she had a history of right hemiparesis and dysarthria, which resolved soon after treatment. Magnetic resonance imaging (MRI) revealed an ischemic legion in the left corona radiata. Then 4 months before coming, she had repeated transient right hemiparesis and dysarthria, which lasted for 40 to 50 minutes and recurred 3 to 4 times a week. She was hospitalized and treated with an intensive TIA therapy including direct thrombin inhibitor, dual antiplatelet therapy, statin, calcium channel blocker and benzodiazepine. Though she continued the therapy for 4 months, it proved ineffective. She was referred to our clinic, and we started to administer chotosan 7.5 g per day for anxiety and dizziness during an attack. Chotosan attenuated TIA within a week, but aggravated after discontinuation on her own. The medication was resumed and TIA diminished within three months. Chotosan treatment has now been continued for 17 months without a single TIA for 14 months. Multiple studies have shown the protective effect of chotosan against cerebrovascular diseases including cerebral infarction and TIA. Therefore, chotosan may be an effective prescription for refractory TIA.
