RESUMEN
Two published case reports described palliation of disease after Seihai-to therapy for refractory aspiration pneumonia caused by recurrent laryngeal nerve paralysis and cerebrovascular disease. We undertook an open-label trial in patients with relapsing aspiration pneumonia. Fifteen patients with relapsing aspiration pneumonia were randomly divided into conventional therapy group (n = 8) or Seihai-to group (n = 7). In Seihai-to group, patients were treated with Seihai-to in addition to conventional therapy (Western medicines). Frequency of feverish days and antibiotics-use, CRP value and chest CT or X-ray findings were compared between the two groups during the study period of 16 weeks. In the Seihai-to group, the latency of swallowing reflex was measured in 6 patients before and after administration of Seihai-to. The mean values of fever index, CRP value and antibiotics-use in the Seihai-to group were decreased significantly, compared with those of the conventional therapy group. However, the latency of the swallowing reflex after 4 weeks of treatment was not significantly changed (p = 0.249), compared with the latency before administration of Seihai-to. No adverse reaction was observed in either group. Seihai-to was effective in reducing relapse of aspiration pneumonia in this small group. Seihai-to might not improve the swallowing reflex, but might instead improve a defense mechanism or excessive inflammation caused by pneumonia in the lower airway. Further evaluation of Seihai-to therapy for patients with aspiration pneumonia in a larger population is warranted.

Continuous hyperthermic peritoneal perfusion (CHPP) with anticancer agents (mitomycin C and cisplatin) in warm saline was performed in patients with peritoneal dissemination of gastric cancer following resection of the primary lesion. The effect of CHPP was examined by a second-look operation. This study includes 41 cases of gastric cancer with peritoneal dissemination but without liver metastasis treated during the past 6 years. The overall median survival was 14.6 months to 64.2 months from CHPP to death and the 3-year survival rate was 28.5%. Second look surgery revealed a remarkable diminution in the degree of peritoneal dissemination in 7 (50%) of 14 patients with disappearance of ascites after only one course of CHPP in 7 (77.8%) of 9 patients. Long-term 3 year-survival was noted in 4 (9.8%) patients on CHPP. Side effects were renal insufficiency in 2 (5%) patients, leukopenia in 2 (5%) patients, and perforation of the small intestine in 1 (2%) patient. These results suggest the effectiveness of CHPP in the treatment of gastric cancer with peritoneal dissemination.

Thermochemotherapy was performed on gastric cancer cases of hepato-metastasis. The subjects were 12 gastric cancer cases having hepato-metastatic lesions (10 synchronous, 2 heterochronous). Using 8 or 13.58 MHz-dielectric heating apparatus, thermotherapy was carried out for 40-60 min (twice a week, 5-35 times, averaging 12.8 per case) at an intra-tumoral temperature greater than 42 degrees C. Chemotherapy consisted of hepato-arterial infusion of MMC 10 mg/BW, CDDP 75 mg/m2 once per 3-4 weeks and consecutive daily administration p.o. of UFT 800 mg/BW. Effect greater than PR was noted in 75% (9/12) on the whole and in 100% (5/5) and 57% (4/7) for H1-2 and H3, respectively. Mean and 50% survival periods were 9.3 and 7.2 months, respectively, with a one-year survival rate of 38%. Chemotherapy-induced side effects were nausea and vomiting in 83% and leukopenia and thrombopenia in 67%, while the only thermotherapy-induced side effect was subcutaneous fatty tissue necrosis in 3 cases. The above results suggested the effectiveness of the present thermochemotherapy in the treatment of hepato-metastasis of gastric cancer.

Following the resection of its primary lesion, continuous hyperthermic peritoneal perfusion (CHPP) with anticancer drug (mitomycin C, cisplatin) containing warmed physiological saline was performed on gastric cancer having peritoneal dissemination, and the effect of CHPP was examined by second look operation (SLO). The subjects were 41 cases of gastric cancer with peritoneal dissemination but without hepatic metastasis, which we have experienced in the past 7 years. The prognosis of these CHPP-treated cases was such that 50% survival period, 3 year survival rate and 5 year survival rate were 398 days, 28.5 and 12%, respectively. Comparison of the effects of CHPP by SLO revealed remarkable diminution of the peritoneal dissemination in 7 (44%) of 16 cases and disappearance of the ascites with a single course of CHPP in 7 of ascitic cases. Long-term survival (greater than 3 years) was noted in 4 of the CHPP-treated cases. Side effects were renal insufficiency, leukopenia and small intestinal perforation in 2(5), 2(5) and 1 cases (2%), respectively. The above results suggested the effectiveness of CHPP for the treatment of gastric cancer having peritoneal dissemination.

A total of 31 patients with gastric cancer showing peritoneal dissemination received continuous hyperthermic peritoneal perfusion (CHPP) in combination with the administration of cisplatin (CDDP) and mitomycin C (MMC). The authors developed a new special device named the peritoneal cavity expander (PCE) for sufficient perfusion and direct temperature measurement in the peritoneal cavity. As complications of CHPP three patients presented with bone marrow suppressions (leukocytes less than or equal to 3000/mm3 and/or platelets less than or equal to 30,000/mm3): one, leakage of intestinal anastomosis; one, intestinal perforation; and one, acute renal failure. But none of them was lethal. Twelve of 31 patients who had received CHPP during the initial operation underwent second-look operation (SLO) for the assessing the effects of CHPP and for resecting residual or recurrent tumors. Among 12 patients who received SLO complete response (CR) was observed in four patients, partial response (PR) in one, no change (NC) in three, and progressive disease (PD) in four, with the overall response rates (%CR + %PR) standing at 41%. Two-year survival rate of the complete and partial responders was 50%, which was significantly higher than 0% of the other responders (NC + PD). The survival curves of the two groups were significantly different (P less than 0.05, generalized Wilcoxon test). These results supported that CHPP was well tolerated and effective for the treatment of patients with peritoneal dissemination in gastric cancer when combined with anti-cancer drugs having synergism with hyperthermia. Since the outcome of SLO was one of prognostic factors it was important to follow up these patients by SLO.

A 60-year-old woman was diagnosed as having liver metastasis from gastric cancer 14 months after total gastrectomy and total pancreatectomy. The liver tumor was so huge and the complication, diabetes mellitus, was so severe that she was palliatively treated by hyperthermo-chemo-radiotherapy (HCR therapy) with 8-MHz capacitive heating system. Because hyperthermia for deep seated tumor is very difficult, irradiation (10 MV X-ray, 36 Gy) and systemic chemotherapy (CDDP, MMC) were combinedly used. After 10 session of hyperthermia, the tumor showed a remarkable regression in size, followed by S8 subsegmentectomy of the liver. Histologically, cancer cells were still viable in the midst of fibrosis around coagulation necrosis, while normal liver cells remained intact. Multidisciplinary HCR therapy is quite a useful modality for liver tumors and may serve to expand the indication for surgical operation.

We carried out a combination preoperative therapy involving radiofrequency hyperthermia (8 MHz or 13.56 MHz) with radiation (10-MV X-ray) or chemotherapy (Mitomycin C, CDDP or UFT) for 24 advanced gastric cancers with the aim of preventing local recurrence and improving resectability. The tumor and histological effects were evaluated in each case. Furthermore, an agar phantom possessing a cavity, for simulating the stomach, was employed in an experiment to evaluate temperature distribution upon RF-heating. In the experiment using the agar phantom, the rising temperature around the cavity at 3 o'clock was higher than at 5' and 6 o'clock. This suggested that gastric juice and air must be aspirated when treating a patient by RF-heating. Of the 24 tumors, 4 (17%) showed partial response. Histological effects were observed in 67% of 21 primary tumors. The rate of histological effects in metastases of lymph nodes, liver and peritoneum were 29% (4/14), 100% (2/2) and 0% (0/4), respectively. Tumor response was closely correlated with irradiation and the temperature in the stomach cavity (over 42.5 degrees C). Almost all patients showed good tolerance of this combined therapy. These results show that combined treatment involving radiation, chemotherapy and hyperthermia appears to be a potentially useful from of preoperative therapy for patients with advanced gastric cancer.

Ninety one patients with unstable angina were evaluated by clinical and angiographic study. Of 91 patients, 42 (46%) responded poorly to the intensive medical treatment. Emergency coronary arteriography was then performed on these patients. The important pathoanatomical mechanisms contributing to instability of angina pectoris and/or refractoriness to the intensive medical treatment were observed in 19 of 42 patients (45%). These include: 1) More severe disease with left main lesion; 2) Refractory coronary spasm; 3) Coronary dissection; 4) Rapid progression of atherosclerosis; 5) Ulcerating plaque and 6) Coronary thrombus. Our results presented here suggest that an appropriate knowledge regarding pathophysiology might improve the approach to treatment.

A 72-year-old woman developed adenocarcinoma of the left parotid gland. Because of the excessive size of her tumor and the fact that she suffered from severe liver dysfunction, she was treated by hyperthermo-chemo-radiotherapy (HCR therapy). After ten sessions of radiofrequency hyperthermia with HEH 500 (13.56 MHz radiofrequency wave), 50-Gy irradiation from a linac and administration of 33.0g of tegafur in suppository form, the tumor mass showed remarkable regression decreasing in size by as much as 84% on computed tomography. Histologically the tumor which was resected under local anesthesia, showed almost total necrosis. The multidisciplinary HCR therapy was well tolerated and effective as a therapy for cancer in this case.
