From these results, the feasibility of the weekday-on/weekend-off schedule was judged to be good. It is suggested that the feasibility would be even better if the dose of UFT was set according to body surface area.

Longevity of patients with unresectable synchronous liver metastases from colorectal cancer is affected adversely by the presence of nodal metastases and extent of liver metastases. This should be considered in the planning treatment.

Large microvessels in the primary tumor favor intravasation of cancer cells.

Symptoms of Systemic Inflammatory Response Syndrome (SIRS) presenting immediately after surgery have lately been regarded as potential warnings of impending postoperative complications and multiple organ failure. Reports discussing the relationship between operative stress and SIRS are found in the field of digestive surgery, but not in that of oral surgery. Sixty-five patients with jaw deformity who had undergone maxillary and mandibular orthognathic surgery (Le Fort I osteotomy and sagittal splitting ramus osteotomy) between September 2003 and October 2006 were involved in this study. A search based on the SIRS diagnostic criteria resulted in assignment of 33 cases to the SIRS group and 32 cases to the non-SIRS group. Postoperative complications occurred in 27.3% of the SIRS group and 0.0% of the non-SIRS group (pϽ0.01). In four cases, a postoperative fluctuation in IL-6 level evaluated. These results suggest the importance of careful management of postoperative SIRS patients in preventing complications.

Erythropoiesis-stimulating agent (ESA) has been recognized as an effective way in the treatment of anemia due to chronic kidney disease, but we sometimes see intractable hemodialysis (HD) patients. The causes of ESA-resistant anemia in HD patients include deficiency of trace elements. We report the case of an 89-year-old male who developed pancytopenia after taking an excessive amount of zinc formulation for ESA-resistant anemia during maintenance dialysis. He was prescribed zinc acetate hydrate formulation about 6 months before his presentation. He was found to have pancytopenia 1 month before his presentation, at which point he was introduced to our hospital. We suspected a copper deficiency at the first visit and stopped zinc and added copper, and his condition subsequently improved without being handicapped. Zinc antagonizes copper, so we must take care to diagnose patients ingesting zinc supplements.

BACKGROUND: The deleterious effect of blood transfusions on survival has been reported in patients with cancers of various organs. However, it remains unclear whether there is any adverse effect of blood transfusion when the patients are administered anticancer drugs after surgery for gastric cancers.METHODS: Data from patients with gastric resection for advanced gastric cancer were retrospectively analyzed to determine the influence of perioperative blood transfusion on the survival rate. All patients were administered anticancer drugs (mitomycin C [MMC] and tegafur-uracil [UFT]). Sixty-nine (33%) of 208 patients received blood transfusion perioperatively, while 139 patients (67%) did not receive transfusion. Multivariate analysis of clinicopathologic prognostic factors, including blood transfusion, was performed. Lymphocyte subsets were measured to investigate the immunosuppressive effect of blood transfusion.RESULTS: The 5-year survival rate was 48.8% in the 69 transfused patients and 66.9% in the 139 non-transfused patients ( P < 0.01). Cox's multiple regression analysis showed that, when patients received anticancer drugs, perioperative blood transfusion was not a significant factor affecting survival after the gastric cancer surgery. However, the CD4/CD8 ratio at 3 months after the surgery was significantly lower in the transfused group than in the non-transfused group.CONCLUSION: Blood transfusion did not affect the survival of operated patients who received postoperative adjuvant chemotherapy. However, the finding that the ratio of CD4/CD8 after surgery was significantly higher in the non-transfused group than in the transfused group supports the notion that transfusion causes broad-spectrum immunosuppression.
