Chemotherapy-induced neutropenia is a common complication in cancer treatment. In this study, we investigated chemotherapy-induced that was recently detected all patients with gynecologic malignancy. Between January 2009 and December 2011, examined cases of reported our hospital. We analyzed the incidence clinical features febrile During study period, administered over 1614 infusions (29 regimens) to 291 patients. The median age 60 years (range 24-84 years). occurred 147 (50.5%) 378 (23.4%)...

The residual tumor after surgery is the most significant prognostic factor of patients with epithelial ovarian cancer. Near-infrared (NIR) fluorescence-guided actively utilized for localization and complete resection during surgery. However, currently available contrast-enhancing agents display low on-target binding, unfavorable pharmacokinetics, toxicity, thus not ideal clinical use. Here we report ultrabright stable squaraine fluorophores optimal pharmacokinetics by introducing an...

Clear cell adenocarcinomas (CA), unlike serous (SA) of the ovary, are often at stage I, resistant to platinum-based drugs and have a poor prognosis. The causes these differences unclear. In this study, in progression between CA SA were examined terms apoptosis-related tumor invasion-related factors. 16 cases reviewed. Excised tissues classified into primary or metastatic loci, expressions survivin, Bcl-2 matrix metalloproteinase-2 (MMP-2) each locus immunohistochemically assayed. Whether...

Objective: In Japan, the possible adverse events upon HPV vaccination was widely reported in media. MHLW announced suspension of aggressively encouraging 2013, and inoculation rate has sharply declined. The aim present study estimation future cervical cancer risk.Methods: latest data on at each age Sakai City were first investigated. experiencing sexual intercourse 12, 13, 14, 15, 16, 17 throughout lifetime is assumed to be 0%, 1%, 2%, 5%, 15%, 25%, 85% respectively. risk regarded...

Uterine smooth muscle tumors (SMTs) are common pelvic in women, and most of them diagnosed as usual leiomyoma (UL). Exclusion malignant disease is important the management SMTs. However, differentiation SMTs remains difficult. In this study, we aimed to improve preoperative diagnosis We examined 21 ULs, 7 atypical leiomyomas (ALs), 6 leiomyosarcomas (LMSs), all which were by uterine tumor biopsy. Immunohistochemical findings (low-molecular-mass polypeptide 2 (LMP2) Ki-67) clinical features...

In Japan, new HPV immunizations have dropped dramatically after repeated adverse media reports and a June 2013 temporary suspension of the government's recommendation for vaccine. The aim present study was to develop an efficient strategy improve immunization coverage across Japan.We conducted internet survey in Japan mothers 12-16 year-old girls who were unvaccinated as May, 2015. goal gather behavioral information from improving Japanese coverage.Valid answers obtained 2060 mothers. found...

Vaginal melanoma is a rare tumor, accounting for <1% of all melanomas and ~1-5% vaginal malignant tumors. The prognosis extremely poor, as it often resistant to chemotherapy radiotherapy, metastases may develop in the early stages disease. present study investigated 5 patients with treated at Department Gynecology Osaka City University Hospital (Osaka, Japan) between October, 2000 April, 2014. All cases presented abnormal genital bleeding main complaint. Notably, 3 tumors appeared...

Concurrent chemoradiotherapy is the standard treatment for locally advanced uterine cervical cancer. However, effective neoadjuvant chemotherapy (NAC) can reduce tumor size and facilitate hysterectomy NAC could improve prognosis of patients with if ineffective, radiotherapy must be pursued. This causes a delay in initiating core results worse prognosis. Therefore, identification predictive markers whether likely to cancer patient Uncoupling protein 2 (UCP2) broadly expressed cells,...

In Japan, the trend for cervical cancer at younger ages has been increasing. As a countermeasure, HPV vaccine was introduced as routine vaccination in April 2013. However, Ministry of Health, Labour and Welfare (MHLW) announced "Suspension its active inoculation recommendation vaccine" June 2016, 32 months after that suspension, we conducted survey via Internet compared results with our previous ones 9 23 suspension (in 2014 2015, respectively). We examined 'time-dependent change' 'intention...

Introduction Uterine leiomyoma is a benign smooth muscle tumor. It does not necessarily require curative treatment, but if conservative management chosen, it important to rule out uterine leiomyosarcoma. When size increase observed, one must consider malignancy, and thus objective cost-effective measurement of important, especially for early detection malignant change. Although MRI imaging thought be the gold standard diagnosis leiomyosarcoma, frequent impractical because incidence economic...
