Comparing Injection Site Reactions of Aprepitant and Fosaprepitant in Gynecologic Cancer Chemotherapy.

Background/aim: The frequency rate of injection site reactions (ISR) due to fosaprepitant meglumine (Fos APR) has been shown to vary depending on the types of combined anticancer drug. This study aimed to elucidate the impact of Fos APR on ISR in patients receiving paclitaxel and carboplatin, with and without bevacizumab therapy (TC±Bev).

Patients And Methods: This study focused on patients with gynecologic cancer (n=93) who received TC±Bev administration at Fujita Health University Hospital from March 2016 to February 2020, and monitored up to six cycles.

A case of primary signet-ring cell carcinoma of the cervix containing full genome of human papillomavirus 16.

We herein present a case of primary signet-ring cell carcinoma of the cervix. Pelvic magnetic resonance imaging revealed a 38-mm cervical tumor, and computed tomography revealed no findings suggestive of distal metastasis or other tumor origins. Gastrointestinal endoscopy showed no abnormal findings.

Preliminary therapeutic outcomes of using direct oral anticoagulants to treat venous thromboembolism in gynecological cancer patients.

Objectives: Venous thromboembolism (VTE) is often a problematic complication in patients with gynecological cancer. Despite increasing opportunities to use direct oral anticoagulants (DOACs) to treat VTE, there are no reports on the therapeutic outcomes of DOACs in patients with gynecological cancer; however, there are some studies on cancer patients in general. We retrospectively examined the efficacy and safety of using DOACs to treat VTE in such patients.

Identification of miRNAs in cervical mucus as a novel diagnostic marker for cervical neoplasia.

microRNAs (miRNAs) play important roles in regulation of gene expression during cervical carcinogenesis. We investigated expression profiles of miRNAs in cervical cancer and its precursor lesions by utilizing cervical mucus. Cervical mucus was collected from 230 patients with a normal cervix, cervical intraepithelial neoplasia (CIN), squamous cell carcinoma (SCC), or adenocarcinoma (AD).

Comparison of methods using paraffin-embedded tissues and exfoliated cervical cells to evaluate human papillomavirus genotype attribution.

Monitoring the attribution of human papillomavirus (HPV) genotypes to cervical precancerous lesions is essential in assessing the efficacy of HPV vaccines. To resolve the lack of studies comparing the HPV genotyping procedures used to estimate HPV genotype attribution, we undertook a retrospective cross-sectional study to determine the appropriate genotyping procedures for evaluating the potential efficacy of HPV vaccines. Three procedures, including two different genotyping methods, Clinichip HPV test (C-Chip) and modified GP5+/6+ PCR coupled to fluorescent bead sorter detection (MGP), using exfoliated cervical cells (C-Chip and C-MGP, respectively) or formalin-fixed paraffin-embedded tissues (F-MGP), were compared.

Factors affecting platinum sensitivity in cervical cancer.

The present study aimed to investigate the association between nedaplatin (NDP) sensitivity and the expression of biological factors in cervical cancer. A total of 45 cervical cancer specimens, including 18 pretreatment biopsies and 27 surgical specimens, were used in histoculture drug response assays to determine the chemosensitivity of cervical cancer specimens to NDP. Each specimen was assessed for immunohistochemical expression of Ki-67, p53, B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), cleaved caspase-3, cyclooxygenase-2 (COX-2), and excision repair cross-complementation group 1 (ERCC1).

Cytological scoring and prognosis of poorly differentiated endometrioid adenocarcinoma.

Objective: Histopathological variation has been demonstrated in grade 3 endometrioid adenocarcinomas. We attempted to evaluate the clinicopathological features of grade 3 tumors by endometrial cytological features using a scoring system.

Study Design: Twenty-one endometrial cytological samples were evaluated using 5 cytological features: rates of cluster formation in tumor cells; nuclear pleomorphism; nuclear dimension; size of nucleoli, and chromatin structure and distribution.

Retrospective comparative study of irinotecan and pegylated liposomal doxorubicin for platinum-resistant or -refractory epithelial ovarian and primary peritoneal carcinoma.

Purpose: This study was conducted to retrospectively compare the efficacy and safety of irinotecan (CPT-11) and pegylated liposomal doxorubicin (PLD) in patients with platinum-resistant or -refractory recurrent epithelial ovarian and primary peritoneal carcinoma.

Methods: Nineteen patients who received CPT-11 and eleven patients who received PLD were enrolled. CPT-11 was intravenously administered at a starting dose of 60-100 mg/m(2) on day 1, 8, and 15 every 28 days, and PLD was administered at a starting dose of 40-50 mg/m(2) on day 1 every 28 days.

ERCC1 expression and chemosensitivity in uterine cervical adenocarcinoma cells.

Unlabelled: BACKGROUD/AIM: We previously demonstrated that high protein expression of excision repair cross-complementation group-1 (ERCC1) was associated with poor disease-free survival in patients who received adjuvant cisplatin-based chemotherapy or chemoradiotherapy with cisplatin, and was shown to be an independent prognostic factor. In the present study, we evaluated ERCC1 expression levels in uterine cervical adenocarcinoma cell lines to assess whether they are affected by treatment with cisplatin with and without 5-fluorouracil (5-FU).

Materials And Methods: Firstly, half-maximal (50%) inhibitory concentration (IC50) values for cisplatin or 5-FU were calculated in cervical adenocarcinoma, HCA-1, and TCO-2 cell lines by 3-(4,5-di-methylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, yellow tetrazole (MTT) assay.

Overcoming paclitaxel resistance in uterine endometrial cancer using a COX-2 inhibitor.

Cyclooxygenase (COX)-2 inhibitors have been reported to potentially modulate the resistance of cancer cells to chemotherapeutic drugs by affecting multidrug resistance 1 (MDR1) expression. In the present study, we investigated the association between COX-2 and MDR1 expression in endometrial cancers and evaluated the effects of the COX-2 inhibitor, etodolac, in combination with paclitaxel on paclitaxel-resistant endometrial cancer cells. The relationship between COX-2 and MDR1 mRNA expression was examined by quantitative PCR in 36 endometrial cancer specimens.

Human epidermal growth factor receptor-2 overexpression and amplification in metastatic and recurrent high grade or type 2 endometrial carcinomas.

Introduction: Human epidermal growth factor receptor (HER)-2 overexpression or gene amplification is more common in high-grade or type 2 endometrial carcinomas. We assessed the discordance of HER-2 expression between primary and metastatic or recurrent endometrial carcinomas.

Materials And Methods: Thirty-six primary, along with 14 metastatic and five recurrent tumors (matched to primaries), pathologically confirmed as high-grade or type 2 endometrial carcinomas, were submitted for immunohistochemistry (IHC) for HER-2.

The relationship between ERCC1 expression and clinical outcome in patients with FIGO stage I to stage II uterine cervical adenocarcinoma.

Objective: Several studies have suggested that excision repair cross-complementation group 1 (ERCC1), a protein involved in nucleotide excision repair, is associated with resistance to platinum agent-based chemotherapy or chemoradiotherapy with platinum agents in various types of cancer. Herein we evaluated ERCC1 protein expression in uterine cervical adenocarcinoma and the relationship between this expression, clinicopathological factors, and clinical outcome, particularly in patients receiving adjuvant cisplatin-based chemotherapy or chemoradiotherapy with cisplatin.

Methods: Thirty-six patients with International Federation of Gynecology and Obstetrics (FIGO) stage IB to stage IIB cervical adenocarcinoma who underwent radical hysterectomy were evaluated.

[Treatment outcomes for advanced ovarian cancers with peritoneal dissemination].

Purpose: The prognosis of advanced ovarian cancer primarily depends on maximal surgical debulking and chemosensitivity of the tumor. Neo-adjuvant chemotherapy(NAC), maintenance chemotherapy, and interval debulking surgery(IDS)are sometimes used to improve the prognosis of advanced ovarian cancer patients. In this study, we evaluated the outcomes of these therapeutic options in the treatment of FIGO stage III and IV ovarian cancers with intraperitoneal dissemination.

Effects of a selective COX-2 inhibitor in patients with uterine endometrial cancers.

Purpose: COX-2 is highly expressed in endometrial cancers, suggesting that a selective COX-2 inhibitor could be valuable for treating endometrial cancers that overexpress COX-2. In this study, we investigated the anti-tumor effects of the selective COX-2 inhibitor etodolac on endometrial cancer patients.

Methods: Etodolac (400 mg, bid, for 2 weeks) was administered preoperatively to 21 endometrial cancer patients who had provided informed consent.

A case of primary uterine cervical neuroendocrine tumor with meningeal carcinomatosis confirmed by diagnostic imaging and autopsy.

Primary uterine cervical neuroendocrine tumors are rare, but affect relatively young women and the prognosis is poor despite multidisciplinary treatment. The incidence of meningeal carcinomatosis arising from malignant tumors of the uterine cervix is extremely low, only two patients with meningeal carcinomatosis arising from a uterine cervical neuroendocrine tumor have been reported in the English literature. Moreover, there have been no reports in which this was confirmed at autopsy.

Expression of podoplanin in epithelial ovarian carcinomas and its potential as a marker for clear cell adenocarcinoma.

Podoplanin is a 43-kd mucin-type transmembrane glycoprotein that is a candidate marker for the pathologic diagnosis of mesothelioma and lymphatic endothelial cells and lymphangiogenesis. The aim of this study was to investigate podoplanin expression in epithelial ovarian carcinomas. Immunohistochemistry was performed on the paraffin-embedded tissues from 78 patients with epithelial ovarian carcinomas consisting of serous adenocarcinoma (SA), endometrioid adenocarcinoma (EM), mucinous adenocarcinoma (MA), and clear cell adenocarcinoma (CCC) cases.
