Currently, the main regimen of neoadjuvant chemotherapy (NAC) used in NCS includes cisplatin. The antitumor effects of NAC reduce lymph node metastasis and the tumor diameter in patients prior to surgery, and this can reduce the number of high risk patients who require postoperative radiation therapy. Many randomized controlled trials (RCTs) have examined the long-term prognosis of NCS compared to primary surgery, but the utility of NCS remains uncertain. The advent of concurrent chemoradiotherapy (CCRT) has markedly improved the outcome of radiotherapy (RT), and CCRT is now used as a standard method in many cases of advanced bulky cervical cancer. NCS gives a better treatment outcome than radiation therapy alone, but it is important to verify that NCS gives a similar or better outcome compared to CCRT.展开更多

The aim of this study was to investigate chronological change in MR-ADL among chronic dialysis patients in need of long-term care and the effect of admission to long-term care facilities on their MR-ADL. Methods: Data were analyzed from a long-term care eligibility assessment survey conducted in late March 2009 of 1000 individuals residing in Niigata City, Japan who were approved to receive long-term care. Then data from those individuals who had undergone the assessment survey ≥4 times over a period of ≥4 years were statistically evaluated. To reveal change in MR-ADL, this study performed a three-way analysis of variance with mean survey scores from assessment categories 2 - 5 containing questions related to MR-ADL as the independent variable and the number of eligibility assessment surveys (within-subjects factor), facility admission, and dialysis therapy (between-subjects factors) as dependent variables. Results: We observed the effect of facility admission in individuals aged >70 years for categories 2 - 5, and observed the effect of the number of assessment surveys taken only in women ≥80 years for categories 2 and 5. Regarding the effect of dialysis therapy, female dialysis patients aged ≥80 years and in need of long-term care scored significantly higher on survey items for transferring, grooming, toileting, eating, and instrumental activities of daily living, all of which are indicators of a moderate decline in ADL. Conclusions: Because dialysis is often initiated in women aged around 80 years, ADL in this group of individuals can be improved by the initiation and proper provision of dialysis.展开更多

Many are caused by benign diseases such as lobular endocervical glandular hyperplasia (LEGH), and it is important to differentiate these lesions from those due to malignant diseases such as minimal deviation adenocarcinoma (MDA). In cases in which fertility preservation is not a concern, the final pathology is often confirmed by hysterectomy. To investigate the feasibility and safety of laparoscopic surgery for cervical cystic lesions, we retrospectively examined cases in which total laparoscopic hysterectomy (TLH) was performed for diagnosis and treatment. Methods: The subjects were 28 women who underwent TLH from April 2012 to March 2017 at Keio University Hospital. The pre- and post-operative courses of these patients were examined. Results: The average age was 49.4 (range 39 - 65) years and the mean body mass index was 21.7 (16.8 - 30.5) kg/m2. The average operation time was 159 (101 - 314) min and the average bleeding volume was 106.8 (0 - 600) g. There were no severe perioperative complications. The average hospital stay was 8.4 (7 - 14) days. In postoperative pathological diagnosis, 13 cases had benign diseases such as Nabot cysts, there were 14 cases of LEGH, and one patient was diagnosed with MDA. In the MDA case, additional bilateral salpingo-oophorectomy and pelvic lymph node dissection were performed at a later date. No metastasis was observed in these excised specimens. Conclusions: Our results suggest that TLH for cervical cystic lesions can be performed safely. However, it is important to consider the TLH indication before surgery based on the possibility of malignant disease.展开更多
