Pharyngeal cancer patients treated with intensity-modulated proton therapy (IMPT) using a model-based approach were retrospectively reviewed, and acute toxicities were analyzed. From June 2016 to March 2019, 15 pharyngeal (7 naso-, 5 oro- and 3 hypo-pharyngeal) cancer patients received IMPT with robust optimization. Simulation plans for IMPT and intensity-modulated X-ray therapy (IMXT) were generated before treatment. We also reviewed 127 pharyngeal cancer patients with IMXT in the same treatment period. In the simulation planning comparison, all of the normal-tissue complication probability values for dysphagia, dysgeusia, tube-feeding dependence and xerostomia were lower for IMPT than for IMXT in the 15 patients. After completing IMPT, 13 patients completed the evaluation, and 12 of these patients had a complete response. The proportions of patients who experienced grade 2 or worse acute toxicities in the IMPT and IMXT cohorts were 21.4 and 56.5% for dysphagia (P < 0.05), 46.7 and 76.3% for dysgeusia (P < 0.05), 73.3 and 62.8% for xerostomia (P = 0.43), 73.3 and 90.6% for mucositis (P = 0.08) and 66.7 and 76.4% for dermatitis (P = 0.42), respectively. Multivariate analysis revealed that IMPT was independently associated with a lower rate of grade 2 or worse dysphagia and dysgeusia. After propensity score matching, 12 pairs of IMPT and IMXT patients were selected. Dysphagia was also statistically lower in IMPT than in IMXT (P < 0.05). IMPT using a model-based approach may have clinical benefits for acute dysphagia. 相似文献

A multi-center, randomized controlled collaborative study was conducted in 310 institutions located throughout Japan for 3 years and 9 months from February 1985 until October 1988 to evaluate the efficacy of post-operative adjuvant therapy for patients who had previously undergone curative surgery for treatment of Stage IIIa breast cancer. Patients with estrogen receptor-positive [ER( + )] breast cancer were treated with two types of regimens, ie, cyclophosphamide + adriamycin + fluorouracil (CAF; 2 cycles) + Futraful (FT) or CAF (2 cycles) + FT + tamoxifen (TAM), and the clinical benefit of additional use of TAM was evaluated. Of the 509 ER( + ) patients registered for the trial, 473 patients (92.9%) were eligible for evaluation. The 5-year survival rate was 77.2% for the CAF + FT group and 74.6% for the CAF + FT+TAM group, and the 5-year disease-free survival rate was 56.7% for the CAF+FT group and 59.2% for the CAF + FT + TAM group. Neither the survival rate nor the disease-free survival rate differed significantly between the groups. Analyses by factor revealed that the 5-year disease-free rate for lymph node-negative patients in the CAF + FT + TAM group was significantly higher than that for the corresponding patients in the CAF + FT group. No differences were noted in the incidence of adverse reactions between the two treatment groups, other than an increase in LDH (the frequency of which was higher in the CAF + FT+TAM group than in the CAF + FT group). Patients with estrogen receptor-negative [ER( -)] breast cancer were treated with two types of regimens, ie, CAF + FT or CAF + FT + adriamycin (ADR), and the clinical benefit of the combined use of intermittent doses of ADR was evaluated. Of the 514 ER(-) patients registered in the trial, 478 (93.0%) were eligible for evaluation. The 5-year survival rate was 64.9% for the CAF + FT group and 63.0% for the CAF + FT + ADR group, and the 5-year disease-free survival rate was 59.2% for both CAF + FT and CAF + FT + ADR groups. Neither the survival rate nor the disease-free survival rate differed significantly between the groups. There were no significant differences between these groups in analyses by nodal or menopausal status. The incidences of adverse reactions including anorexia, nausea/vomiting and alopecia were higher in the CAF + FT+ADR group than in the CAF + FT group. 相似文献

MDM2 protein is thought to bind to p53 tumor suppressor protein leading to inhibition of p53-mediated transactivation. Amplification of the MDM2 gene has been frequently observed in human sarcoma, and relevant overexpression of the MDM2 protein is assumed to contribute to tumorigenesis through inactivation of the p53 function. In order to determine whether MDM2 amplification plays a role in the development of human breast cancer without genetic alteration of p53, we analyzed, MDM2 gene amplification by quantitative hybridization and genetic alteration of p53, in 32 primary tumors and 26 metastatic lymph nodes. Low grade amplification of the MDM2 gene (2-6 fold) was observed in four cases, none of which showed even subtle genetic alterations of p53 or loss of alleles on 17p. Moreover, in three of the four cases with MDM2 gene amplification, the level of gene amplification in the metastatic lymph nodes was slightly higher than that in the primary tumors. These results, taken together with previous findings, suggest that a subset of breast cancers without genetic alteration of p53 may also arise by inactivation of the p53 function through interaction with the overexpressed MDM2 protein induced by gene amplification. 相似文献

An experience of indwelling of a urethral stent (Urolume Wallstent) for urethral stricture accompanying pelvic fracture in a young man 总被引:1,自引:0,他引:1
Hanai T Miyatake R Katoh Y Iguchi M Hashimoto K Kurita T 《Hinyokika kiyo. Acta urologica Japonica》1999,45(11):767-770
The patient was a 15-year-old boy, who sustained pelvic fracture and complete disruption of the urethra in a traffic accident. The previous doctor performed two-staged treatment for complete disruption of the urethra, which ended in postoperative urethral stricture. We performed two sessions of endoscopic operations and a pull-through procedure, but the procedures were not effective. Five years later, a urethral stent was indwelt. Urolume Wallstent of AMS, Co, Ltd. was used as the urethral stent. At 4 months, the stent started to be enveloped in the urethral epithelia and no complications have been found in particular. However, detention of a permanent-type stent in a young man such as ours remains a controversial issue and long-term follow-up is needed. 相似文献

Using the Pines' Burnout Scale, we conducted the first nationwide survey in Japan to study burnout among 3,774 staff members in 216 social welfare facilities for persons with mental retardation. Mean burnout scores were significantly higher among direct-care staff members than among facility directors, middle managers, and other types of staff personnel. Burnout scores were significantly lower for staff members who reported having supervisors whom they could consult about work or personal problems than those who reported they could not. Findings suggest that supervisor support can reduce burnout among direct-care staff members at social welfare facilities for persons with mental retardation. 相似文献

Total Esophagectomy versus Proximal Esophagectomy for Esophageal Cancer at the Cervicothoracic Junction 总被引:1,自引:0,他引:1
Fujita H Kakegawa T Yamana H Sueyoshi S Hikita S Mine T Tanaka Y Ishikawa H Shirouzu K Mori K Inoue Y Tanabe HY Kiyokawa K Tai Y Inutsuka H 《World journal of surgery》1999,23(5):486-491
To investigate the adequate extent of esophagectomy and lymphadenectomy for an esophageal cancer localized at the cervicothoracic
junction, the mortality and morbidity rates, survival rates, and patterns of recurrence were retrospectively analyzed in two
groups—14 patients who underwent total esophagectomy with or without laryngectomy and 15 patients who underwent proximal esophagectomy
with or without laryngectomy—at Kurume University Hospital from 1981 to 1996. Proximal esophagectomy with or without laryngectomy
resulted in a lower hospital mortality rate and better overall survival for patients who underwent curative esophagectomy
compared with total esophagectomy with or without laryngectomy. Multivariate analysis indicated that the extent of esophagectomy
(total esophagectomy versus proximal esophagectomy) was not a prognostic factor. The incidence of recurrence was not different
between the two groups. Lymph node metastasis or recurrence from such esophageal cancers was localized to the neck and upper
mediastinum. For an esophageal cancer localized at the cervicothoracic junction, therefore, proximal esophagectomy with or
without laryngectomy and with cervical and upper mediastinal lymphadenectomy could be better indicated for preselected patients. 相似文献

Endothelin-1 enhances vascular cell adhesion molecule-1 expression in tumor necrosis factor alpha-stimulated vascular endothelial cells 总被引:9,自引:0,他引:9
Ishizuka T Takamizawa-Matsumoto M Suzuki K Kurita A 《European journal of pharmacology》1999,369(2):237-245
Vascular cell adhesion molecule-1 (VCAM-1) is a mononuclear leukocyte-selective adhesion molecule that is expressed in human vascular endothelial cells at sites of local inflammation. It participates in local endothelial-monocyte interactions during the initiation of atherosclerosis. In the present study, endothelin alone did not induce the surface expression and mRNA accumulation of VCAM-1 in human vascular endothelial cells, but inhibition of endogenous nitric oxide (NO) by N(G)-monomethyl-L-arginine enhanced the surface expression and mRNA accumulation of VCAM-1 stimulated by endothelin-1. It is conceivable that in human vascular endothelial cells, stimulation of an endothelin receptor results in the production of nitric oxide (NO), suppressing the expression of VCAM-1. Endothelin-1 enhanced the surface expression and mRNA accumulation of VCAM-1 in cells treated with tumor necrosis factor alpha (TNF-alpha). The enhancement by endothelin-1 may be explained by the inhibitory effect of TNF-alpha on endothelin-induced NO production. Pretreatment with BQ788 (an endothelin ET(B) receptor antagonist) or inhibitors of nuclear factor kappa B (NF-kappaB) activation completely diminished the synergistic enhancement of VCAM-1 expression by endothelin-1 in TNF-alpha-stimulated vascular endothelial cells, both at the protein and mRNA levels. These findings suggest that the synergistic enhancement of VCAM-1 expression by TNF-alpha and endothelin ET(B) receptor stimulation may be augmented by the induction of NF-kappaB binding activity in human vascular endothelial cells. 相似文献
