Background: Olfactory neuroblastoma is a rare sino‐nasal tumor arising from the olfactory epithelium and is often characterized by local invasion or metastasis. The role of chemotherapy in the treatment of this tumor is unclear. The purpose of this study was to review our institution’s experience of chemotherapy for advanced or recurrent olfactory neuroblastoma. Methods: Twenty‐one patients with histologically proven olfactory neuroblastoma were treated at our institution between 1992 and 2002. Twelve of these patients received chemotherapy in the setting of unresectable or recurrent disease and were retrospectively reviewed for clinical characteristics, treatment outcome or survival. Results: Eight patients of the 12 patients received cisplatin‐based chemotherapy and the remaining four patients received chemotherapy consisting of docetaxel plus irinotecan (three patients) or cyclophosphamide, doxorubicin, and vincristine (1 patient). A partial response was achieved in five patients, with an overall response rate of 42%, although the chemotherapeutic regimens were heterogeneous. Two partial responses were obtained among the three patients who received docetaxel plus irinotecan. The response rate to chemotherapy was 83% in the younger age group (<40 years), as opposed to 0% in the older age group (≥40 years), and the difference between the two groups was statistically significant (P = 0.02). Conclusion: Our study indicated that olfactory neuroblastoma would be sensitive to chemotherapy, especially with young patients. Docetaxel plus irinotecan has the possibility of showing favorable response, and warrants further investigation. 相似文献

BACKGROUND: We retrospectively compared the 5-year survival rates of T1b-T3N0M0 prostate cancer patients treated either by endocrine therapy plus radical prostatectomy or endocrine therapy alone. METHODS: Clinical T1b-T3N0M0 prostate cancer patients were enrolled at 104 institutions in Japan. They were assigned to study 1 (n = 176), if they were indicated to prostatectomy, if not indicated, they were assigned to study 2 (n = 151). The indication of prostatectomy was based on the clinical judgement of physicians and/or patients. Those assigned to study 1 underwent prostatectomy and adjuvant endocrine therapy with or without preoperative androgen deprivation. Those assigned to study 2 were treated with leuprorelin acetate with or without chlormadinone acetate. They were followed-up every 3 months until death or for 5 years and over. RESULTS: Those assigned to study 1 were younger (mean age 67.2 vs 75.7 years), less advanced in clinical stage, and had lower prostate specific antigen levels (mean 43.8 vs 103.6 ng/mL). Death for any reason was observed less frequently in study 1 (n = 29, 16%) than study 2 (n = 50, 33%), and the 5-year overall survival rate was higher in study 1 (87 vs. 68%). However, prostate cancer deaths were comparatively seldom (9% in study 1 and 7% in study 2), resulting in the identical 5-year cause specific survival rate in both study groups (91%). In both study groups the overall survival was almost equal to the natural survival of age-matched men. CONCLUSIONS: Endocrine therapy offers a reasonable survival rate in T1b-T3 prostate cancer patients within a 5-year follow-up. Observation will be extended to determine 10-year outcomes. 相似文献

We report five female cases of hypouricaemia accompanied byacute viral hepatitis (serum urate 101 ± 12 µmol/1,mean ± SD). Their urate clearance was increased to 14.2±3.4 ml/min during hyperbilirubinaemia but 24-h urateexcretion was not elevated (2.09 ± 0.64 mmol/24 h). Noother renal tubular abnormalities were detected. Comparing uratemetabolism with that of four cases of inborn renal hypouricaemia,the degree of uricosuria was lower. One patient showed elevationof serum and urinary oxypurine, which normalized with returnof a normal blood uric acid level. In all cases, the serum uratereturned to normal after improvement of liver function. We suggestthat renal uricosuria due to an isolated renal defect of uratetransport might contribute to hypouricaemia in these cases butthat inhibition of xanthine oxidase activity might also contributeto this phenomenon.

ABSTRACT. CRP, α1-acid glycoprotein and haptoglobin were studied in 13 septic shock neonates. Endotoxin was recovered from eight infants. Serum Cortisol concentration from infants with en-dotoxemia (917 ± 596 ng/ml) was significantly higher than that from infants without en-dotoxemia (398 ± 239 ng/ml). Serum Cortisol correlated well with immature neutrophil counts denned as the unit "band/neutrophil". Increased Cortisol level and immature neutrophil counts preceded the elevation of CRP, α1-acid glycoprotein and haptoglobin in four extremely premature neonates. We conclude that positive interactions between endotoxin, Cortisol and acute phase protein synthesis are present in the initial period of infection, and delayed acute phase protein synthesis is suspected in extremely premature neonates. 相似文献

The relationships between histological findings, adaptively increased cytochrome a(+a3) levels in chronic liver disease and complications after hepatectomy were studied in order to clarify the mechanism of mitochondrial derangement. The liver specimens of 53 hepatectomized patients were randomly evaluated by three independent hepatopathologists and were compared with cytochrome a(+a3) levels in the biopsied liver, the extent of operation and postoperative complications. The cytochrome a(+a3) concentrations did not show any significant difference between cases of chronic hepatitis and liver cirrhosis nor groups classified by regeneration. Severity of piecemeal necrosis was categorized into three groups: group A--minimal (n = 20); group B--moderate (n = 19); and group C--severe (n = 14). There were significant differences (P less than 0.01) in cytochrome a(+a3) concentrations between the groups (A: 99 +/- 9; B: 135 +/- 6; C: 155 +/- 10 pmol/mg of mitochondrial protein). Extensive hepatectomy, involving segmentectomy or more, was frequently complicated (four of nine, 44.4%) in group C, whereas there were few complications (two of 16, 12.5%) in group A cases in which extensive hepatectomy was performed. Evidence will be presented which will show that deranged liver function, as indicated by cytochrome a(+a3) levels, is closely correlated with piecemeal necrosis. This may be attributed to the damage of periportal hepatocytes which are the main sites of oxidative phosphorylation. 相似文献

A case of an aneurysm associated with four coronary artery fistulaeoriginating from three vessels is reported. The patient, a 52-year-oldwoman, had chest heaviness and palpitations. Coronary arteriographyreveaed the four fistulae originating from three coronary vesselswith an aneurysm draining into the left ventricle and the mainpulmonary artery.The patient's symptoms were relieved afterfistulectomy and the aneurysmectomy, suggesting that a coronarysteal phenomenon through the fistulae was the cause of her symptoms.This case is of interest because of its rarity, since this isthe first case report of an aneurysm associated with four coronaryartery fistulae from three vessels. 相似文献

BACKGROUND: The effects of preoperative androgen deprivation on the outcomes of prostate cancer patients who received radical prostatectomy and subsequent adjuvant endocrine therapy have not yet been fully evaluated. METHODS: Patients with stage A(2), B or C prostate cancers were randomized to one of two groups: group I (n = 90), who received androgen deprivation (leuprolide and chlormadinone acetate) for 3 months followed by radical prostatectomy and subsequent adjuvant endocrine therapy (leuprolide alone), and group II (n = 86), who underwent the surgery followed by 3-month androgen deprivation (leuprolide and chlormadinone acetate) and subsequent adjuvant endocrine therapy (leuprolide alone). The effects of preoperative androgen deprivation on survival, clinical relapse (serum prostate specific antigen, PSA, above the normal level, local recurrence, or distant metastases), and PSA relapse (PSA above the detectable level) were evaluated at 5 years or later after treatment. RESULTS: There were no significant differences in overall, cause-specific, clinical relapse-free, or PSA relapse-free survival rates between the two groups. In a subanalysis, no prostate cancer deaths or clinical relapses were noted in 29 patients with organ-confined disease (OCD: negativity of capsular invasion, seminal vesicle invasion, surgical margins or nodal involvement). The odds ratio for OCD depending on group assignment was 2.44 (95% confidence interval, CI 1.04-5.72), for group I, demonstrating a higher probability of having OCD. This ratio was increased to 4.00 (95% CI 1.06-15.16) if the analysis was conducted in a subpopulation with prostate specific antigen levels less than 35.6 ng/mL and with clinical stage B or C cancers. CONCLUSION: Preoperative androgen deprivation has no demonstrable benefit in 5-year outcomes for patients undergoing radical prostatectomy and adjuvant endocrine therapy. However, it did increase the probability of OCD, which was associated with no clinical relapse during the follow-up. A longer observation is needed to clarify the exact extent of the benefits in terms of survival. 相似文献

The immunohistochemical localization of copper, zinc-superoxide dismutase (Cu,Zn-SOD) in human gastric mucosa and gastric cancer was studied using a monoclonal antibody. In gastric mucosa, parietal cells, pyloric glandular cells and foci of intestinal metaplasia showed positive staining in the cytoplasm and/or nucleus. The wide distribution of Cu, Zn-SOD in the gastric mucosa suggests cell function may be vulnerable to active oxygen species. In gastric cancer, 34 of 70 cases showed a positive reaction for Cu, Zn-SOD. There was a relationship between the grade of Cu,Zn-SOD immunoreactivity and the histological type of gastric cancer, well-differentiated types of gastric cancer being more frequently positive. The positive cases of poorly-differentiated adenocarcinoma were characterized by a pattern of diffusely infiltrative invasion. These results suggest that some types of gastric cancer are resistant to active oxygen species. 相似文献

Summary: Patients with thin basement membrane disease (TBMD) exhibit persistent haematuria with a diffuse thinning of the glomerular basement membrane (GBM), especially of the lamina densa. It appears to be an autosomal dominant trait. It has been reported that the Goodpasture epitope, which is located in the non-collagenous domain of type IV collagen α 3 chain, may be reduced in patients with TBMD. We speculated that the candidate gene for TBMD could be the type IV collagen α 3 chain gene ( COL4A3 ), which is present closely to type IV collagen α 4 chain gene ( COL4A4 ) on chromosome 2q35–37. We conducted a linkage analysis to investigate the relationship between familial TBMD and COL4A3 gene, using COL4A3 cDNA polymorphism and a (CA)n microsatellite marker located in the COL4A3 gene. We examined 32 individuals from four Japanese families with TBMD. There were no associations between the patients with haematuria and certain alleles of the two markers in the pedigrees of three families. It has been reported that type IV collagen α 1 chain gene ( COL4A1 ) and α 2 chain gene ( COL4A2 ) are not involved in TBMD, and that α 5 chain gene ( COL4A5 ) and a 6 chain gene ( COL4A6 ) map to chromosome X. In conclusion, our findings suggested that familial TBMD is not caused by the genetic abnormalities of type IV collagen genes isolated thus far. 相似文献
