Modified pharmacokinetic modulating chemotherapy using 5-fluorouracil,UFT, and taxotere (docetaxel) for advanced gastric cancer 总被引:2,自引:0,他引:2

The efficacy of neoadjuvant chemotherapy for advanced gastric carcinoma is controversial. Moreover, a standard regimen for such chemotherapy has not been clearly established. Pharmacokinetic modulating chemotherapy (PMC), a combination of infused 5-fluorouracil and oral uracil-tegafur, has been proven to be highly effective for the treatment of colorectal carcinoma. We report two patients with advanced gastric carcinoma successfully treated with PMC and infused taxotere (TXT; docetaxel). Preoperative treatment with PMC and TXT significantly decreased the depth of wall penetration of the tumor in one patient and reduced the size of the tumor in the other patient. In both patients, there were significant chemotherapeutic effects on the primary tumor and on regional lymph nodes pathologically. Preoperative PMC plus TXT produced primary tumor downstaging, leading to improved resectability. The responsiveness of metastatic cancer cells in the regional lymph nodes suggested the possibility of nodal downstaging by this regimen. 相似文献

Biweekly administration regimen of docetaxel combined with CPT-11 in patients with inoperable or recurrent gastric cancer 总被引:2,自引:0,他引:2

Background. Both docetaxel (TXT) and irinotecan (CPT-11) are active chemotherapeutic agents for gastric cancer. We designed a biweekly administration regimen of TXT combined with CPT-11 for 4 weeks as one cycle in patients with inoperable or recurrent gastric cancer, and conducted a dose-escalation study.
Methods. Patients with histologically confirmed gastric cancer were treated with the regimen. The dosage levels of TXT and CPT-11 were as follows: level 1, 30mg/m2 and 50mg/m2; level 2, 35 and 50mg/m2; level 3, 40 and 50mg/m2; level 4, 40 and 60mg/m2; and level 5, 50 and 60mg/m2. The dose escalation was based on the dose-limiting toxicity (DLT) observed during the first cycle.
Results. Grade 4 neutropenia was observed at level 3, but no other DLT was observed at less than level 4 during the first cycle. However, three patients at level 3 could not continue treatment without a decrease in the dosage after the second cycle. Based on these results, level 2 was considered to be the clinically recommended dosages.
Conclusion. Biweekly TXT and CPT-11 was well tolerated. The recommended dosages of TXT and CPT-11 for a phase II trial are 35mg/m2 and 50mg/m2, respectively. 相似文献

The two neuropeptide Y (NPY) systems innervating the hypothalamic paraventrivular nucleus were examined regarding their roles in the prefeeding corticosterone peak developed under restricted daily feeding (RF). Protein and mRNA levels of NPY were measured in the arcuate nucleus (ARC) and the nucleus of the solitary tract (NST) in rats under 48-h food deprivation (48-hFD), RF, and 72-h food deprivation imposed after RF (post-RF 72-hFD) with 7 days of ad libitum feeding in between. NPY protein and mRNA levels in the ARC significantly increased with 48-hFD and decreased with re-feeding, whereas those in the NST were not changed by 48-hFD. When rats had RF imposed with free access to food from 10.00 to 12.00 h (lights on from 06.00 to 18.00 h) for 3 weeks, NPY concentrations in the ARC increased at 10.00 h, just prior to the daily meal, but those in the NST did not change significantly throughout the period examined. On the other hand, NPY mRNA levels in both the ARC and NST increased before the meal supply and remained high for 4 h after feeding. Under post-RF 72-hFD, the prefeeding peak of NPY mRNA was detected in the NST, but NPY mRNA levels in the ARC were continuously high throughout the 24-h period. These findings indicate that the NPY neurons from the NST are specifically activated by RF, whereas those from the ARC are generally stimulated by an increased food demand. 相似文献

Anxiolytic potency of 1 week of treatment with alprazolam or tandospirone in psychiatric outpatients with anxiety disorders was evaluated by changes in the scores on the Hamilton Anxiety Scale and the State and Trait Anxiety Inventory and in the saliva level of free-3-methoxy-4-hydroxyphenylglycol (free-MHPG). Saliva level of free-MHPG was significantly reduced by 1 week of treatment with alprazolam but not with tandospirone. Reductions in the HAS score after 1 week of drug treatment were greater in patients treated with alprazolam than in those treated with tandospirone. These results indicate that the short-term anxiolytic potency of alprazolam is greater than that of tandospirone and that the saliva level of MHPG would be a useful marker for the evaluation of the therapeutic potency of anxiolytic agents.

Objective Exposure to polychlorinated biphenyls (PCBs) is considered to have culminated between 1950 and 1970 in Japan, and exposure
through diet, the major exposure route, has decreased significantly over the last 10 years. The primary goal of the present
study was to investigate the long-term trends and congener profiles of serum and dietary levels of PCBs using historical samples.
Methods Using banked samples collected in 1980, 1995, and 2003 surveys, we determined the daily intakes and serum concentrations of
13 PCB congeners (#74, #99, #118, #138, #146, #153, #156, #163, #164, #170, #180, #182, and #187) in women.
Results The total daily PCB intake [ng/day, geometric mean (geometric standard deviation)] decreased significantly from 523 (2.5)
in 1980 to 63 (3.2) in 2003. The serum total PCB level (ng/g lipid) in women <40 years of age decreased significantly from
185 (1.8) in 1980 to 68 (1.8) in 2003. In contrast, the level in women >50 years of age increased significantly from 125 (1.7)
in 1980 to 242 (1.7) in 2003. Specifically, the serum concentrations of hexa (#138, #146, #153, #156, #163, and #164) and
hepta (#170, #180, #182, and #187) congeners increased significantly. A comparison of the serum PCB levels of women born from
1940 to 1953 revealed that their serum total PCB level was significantly higher in the 2003 survey [242 (1.7), n = 9] than in the 1995 [128 (2.0), n = 17] surveys. This increase in the total PCB level was attributable to increases in the hepta congener groups.
Conclusion Present results suggest a decreased rate of elimination of hepta congeners with aging in females, rather than a birth-generation
phenomenon. 相似文献

Combined chemotherapy including 5-FU plus radiation treatment resulted in a synergistic effect has been reported. S-1 enhances a radiation response of colon cancer cell line xenografts. Also the effectiveness of S-1 + radiation therapy has been reported. A 66-year-old man underwent a low anterior resection for lower rectal cancer. Adjuvant chemotherapy was not performed due to Stage II rectal cancer. Twenty months after the operation, solitary sacral bone metastasis was found during the postoperative work-up. S-1 (120 mg/day) combined with radiotherapy was performed on days 1-14 and 21-35. Radiation (3 Gy) was administered a total of 45 Gy on days 1-5, 7-12 and 35-40. Moreover, the reduction was judged as complete response after 11 courses of mFOLFOX 6. There has been no sign of recurrence for 44 months. It suggested that local control therapy (S-1 + radiation) plus systemic chemotherapy (mFOLFOX6) was one of the promising effective therapies for single sacral bone metastasis of rectal cancer. 相似文献

We describe here a case of accidental electrocution. A 48-year-old male was found dead in his room. At autopsy, there was a current mark on the right thumb and big toe. Histological examination revealed that the skin wound had the characteristics of a current mark, including vacuolation and elongation of the cell nuclei. We could also identify titanium metallization on the skin surface of the current mark using a variable-pressure scanning electron microscope (VP-SEM) equipped with energy dispersive X-ray microanalyser (EDX). The autopsy finding and the subsequent investigation support the conclusion that the cause of his death was electrocution. Our result shows that the VP-SEM with EDX is a useful tool for the forensic diagnosis of electrocution. 相似文献
