The number of dialysis patients in Japan is increasing every year. The medical expense for dialysis patients has now surpassed well over 7 per cent of all medical costs. This has become a great burden on national finance. The D3-30 project was started in April 2006 for Toride city residents. The purpose of this project was a 30% reduction of the yearly number of new dialysis patients in three years. Toride city is located in southern Ibaraki prefecture; it had a population of 112, 152 in fiscal 2006, and 19% of the residents were over 65 years of age. The treatment procedure for chronic kidney disease (CKD) patients at the predialysis stage comprised the following four parts: 1. control of blood pressure, 2. mild restiction of protein and sodium intake, 3. administration of antiproteinuric drugs (angiotensin receptor blocker, angiotensin converting enzyme inhibitor, some calcium channel blocker, etc.), and 4. multifactorial treatment.  CKD patients were recruited through introductions from hospital registered doctors and public health nurses. Some patients entered voluntarily. The number of patients that started dialysis was counted by inquiring at the dialysis center of Toride Kyodo General Hospital and eighteen neighboring dialysis centers. In 2005, before intervention, 36 patients started dialysis; subsequently, the number of patients was 30 in 2006, 33 in 2007, 22 in 2008, and 23 in 2009. The rate of decrease was 39% in 2008 and, 36% in 2009, so the aim of the project was achieved.  If this treatment becomes widespread, it will contribute greatly to the curtailment of medical expenses. However, the difficulty of the treatment may hamper its spread. For it to spread, it is necessary to add the new medical fee for guidance and management for CKD patients.

OBJECTIVE: The purpose of the present study was to elucidate the incidence of deep venous thrombosis (DVT) before treatment in ovarian cancer and the appropriate cut-off value of D-dimer (DD) for the diagnosis of DVT. METHODS: Between July 2007 and October 2008, eighty seven patients with presumed ovarian cancer (final diagnosis: ovarian cancer, n=59; borderline malignancy, n=28) were enrolled. Measurement of DD levels and subsequent venous ultrasonography were performed before treatment. RESULTS: The mean DD level was 4.1 microg/mL. Subsequent venous ultrasonography revealed DVT in 14 of 87 (16.1%) patients (ovarian cancer, 12 cases; borderline malignancy, 2 cases). None were found to have developed DVT if they had a DD level of <1.5 microg/mL. If 1.5 microg/mL was used as a cut-off value for DD levels to diagnose DVT, sensitivity, specificity, positive predictive value, and negative predictive value were 100%, 61.6%, 33.3%, and 100%. There was noclinical onset of postoperative pulmonary thromboembolism. CONCLUSION: Our data suggest that presumed ovarian cancer patients with at least more than 1.5 microg/mL should be examined using venous ultrasonogaphy to detect DVT.

OBJECTIVE: The aim of the present study was to assess prognostic factors for patients with locally advanced cervical cancer treated with radiotherapy as the primary treatment and to assess the posttreatment cut-off levels of squamous cell carcinoma antigen (SCC-Ag) to predict three-year overall survival (OS) rates. METHODS: One hundred and twenty-eight patients with cervical squamous cell carcinoma (International Federation of Gynecology and Obstetrics [FIGO] stage IIB-IVA) treated using radiotherapy or concurrent chemoradiotherapy were identified. Of these patients, 116 who had SCC-Ag levels >1.5 ng/mL prior to treatment were analyzed retrospectively. RESULTS: Median age was 68 years (range, 27 to 79 years). The complete response rate was 70.7% and the three-year OS rate was 61.1%. The median levels of pretreatment and posttreatment SCC-Ag were 11.5 ng/mL (range, 1.6 to 310.0 ng/mL) and 0.9 ng/mL (range, 0.4 to 41.0 ng/mL), respectively. Multivariate analysis showed that pretreatment anemia (p=0.041), pelvic lymph node metastasis (p=0.016) and posttreatment SCC-Ag levels (p=0.001) were independent prognostic factors for three-year OS. The SCC-Ag level cut-off point for three-year OS rates, calculated using a receiver operating characteristic curve, was 1.15 ng/mL (sensitivity, 80.0%; specificity, 74.0%). CONCLUSION: Pretreatment anemia and pelvic lymph node metastasis are poor prognostic factors in locally advanced cervical cancer. Furthermore, posttreatment SCC-Ag levels <1.15 ng/mL predicted better three-year OS rates.

OBJECTIVE: In the present study, we evaluated changes in CA-125 cut-off values predictive of complete interval debulking surgery (IDS) after neoadjuvant chemotherapy (NAC) using receiver operating characteristic (ROC) analysis. METHODS: This retrospective single-institution study included patients with International Federation of Gynecology and Obstetrics (FIGO) stage III epithelial ovarian cancer and a pre-NAC serum CA-125 level of greater than 40 U/mL who were treated with neoadjuvant platinum-based chemotherapy followed by IDS between 1994 and 2009. Logistic regression analysis was used to evaluate univariate and independent multivariate associations with the effect of clinical, pathological, and CA-125 parameters on complete IDS, and ROC analysis was used to determine potential cut-off values of CA-125 for prediction of the possibility of complete IDS. RESULTS: Seventy-five patients were identified. Complete IDS was achieved in 46 (61.3%) patients and non-complete IDS was observed 29 (38.7%). Median pre-NAC CA-125 level was 639 U/mL (range, 57 to 6,539 U/mL) in the complete IDS group and 1,427 U/mL (range, 45 to 10,989 U/mL) in the non-complete IDS group. Median pre-IDS CA-125 level was 15 U/mL (range, 2 to 60 U/mL) in the complete IDS group and 53 U/mL (range, 5 to 980 U/mL) in the non-complete IDS group (p<0.001). Multivariate analyses performed with complete IDS as the endpoint revealed only pre-IDS CA-125 as an independent predictor. The odds ratio of non-complete IDS was 10.861 when the pre-IDS CA-125 level was greater than 20 U/mL. CONCLUSION: The present data suggest that in the setting of IDS after platinum-based NAC for advanced ovarian cancer, a pre-IDS CA-125 level less than 20 U/mL is an independent predictor of complete IDS.
