Japan Society of Gynecologic Oncology guidelines 2017 for the treatment of uterine cervical cancer.

The Japan Society of Gynecologic Oncology (JSGO) Guidelines 2017 for the Treatment of Uterine Cervical Cancer are for the purpose of providing standard treatment strategies for cervical cancer, indicating treatment methods currently considered appropriate for cervical cancer, minimizing variances in treatment methods among institutions, improving the safety of treatment and prognosis of diseases, reducing the economic and psychosomatic burden of patients by promoting performance of appropriate treatment, and enhancing mutual understanding between patients and healthcare professionals. The guidelines were prepared through consensus of the JSGO Guideline Committee, based on careful review of evidence gathered through the literature searches and in view of the medical health insurance system and actual clinical practice situations in Japan. The guidelines comprise eight chapters and five algorithms. The main features of the 2017 revision are as follows: (1) evidence was collected using a search formula and with cooperation of the Japan Library Association. The bibliographical search formula was placed at the end of the book; (2) regarding clinical questions (CQs) where evidence or clinical inspection in Japan was lacking, opinions of the Guidelines Committee were described as "proposals for future directions"; (3) cervical intraepithelial neoplasia (CIN) 3 and adenocarcinoma in situ (AIS) were treated as a cervical precancerous lesion; (4) the CQs of endoscopic surgery, radical trachelectomy, and sentinel node biopsy were newly added in Chapter 3, "primary treatment for stage IB-II cervical cancer"; and (5) the CQ about hormone replacement therapy after cancer treatment was newly established. Each recommendation is accompanied by a classification of recommendation categories based on the consensus reached by the Guideline Committee members. Here, we present the English version of the JSGO Guidelines 2017 for the Treatment of Uterine Cervical Cancer.

Multicenter Clinicopathological Study of High-Grade Serous Carcinoma Presenting as Primary Peritoneal Carcinoma.

OBJECTIVE: We conducted a multicenter clinicopathological study to characterize patients with high-grade serous carcinoma presenting as primary peritoneal carcinoma (clinical PPC). METHODS: At 9 sites in Japan, patients with clinical PPC diagnosed according to Gynecologic Oncology Group criteria were enrolled retrospectively. The Gynecologic Oncology Group criteria allow for minor ovarian involvement by high-grade serous carcinoma. There was no systematic detailed histopathological review of the fallopian tubes to determine whether they were involved by serous carcinoma. RESULTS: There were 139 patients and 64% were aged 60 years or older. Median pretreatment serum CA-125 was 1653.5 IU/mL. Pretreatment performance status was poor in more than 50%, endometrial cytology was positive in 40.3%, and the preoperative clinical diagnosis was correct in 72.7%. Primary debulking surgery was performed in 36% of patients, whereas 64% underwent neoadjuvant chemotherapy (NAC) with interval debulking surgery (IDS). The main tumor sites were the upper abdomen (greater omentum), extrapelvic peritoneum, mesentery, and diaphragm. Lymph node metastasis was found in 46.8% of patients undergoing systematic retroperitoneal node dissection. The optimal surgery rate was 32.0% with primary debulking surgery versus 53.9% with NAC and IDS (P = 0.0139). The response rate was 82.0% with NAC and 80.6% with postoperative chemotherapy. Median progression-free survival was 19.0 months and median overall survival was 41.0 months. Multivariate analysis showed that prognostic factors for progression-free survival were NAC and residual tumor diameter after debulking surgery, whereas the only prognostic factor for overall survival was the residual tumor diameter. CONCLUSIONS: This study identified various characteristics of clinical PPC. Neoadjuvant chemotherapy with IDS is a reasonable treatment strategy, and complete debulking surgery is optimum.

Japan Society of Gynecologic Oncology guidelines 2015 for the treatment of vulvar cancer and vaginal cancer.

BACKGROUND: Vulvar cancer and vaginal cancer are relatively rare tumors, and there had been no established treatment principles or guidelines to treat these rare tumors in Japan. The first version of the Japan Society of Gynecologic Oncology (JSGO) guidelines for the treatment of vulvar cancer and vaginal cancer was published in 2015 in Japanese. OBJECTIVE: The JSGO committee decided to publish the English version of the JSGO guidelines worldwide, and hope it will be a useful guide to physicians in a similar situation as in Japan. METHODS: The guideline was created according to the basic principles in creating the guidelines of JSGO. RESULTS: The guidelines consist of five chapters and five algorithms. Prior to the first chapter, basic items are described including staging classification and history, classification of histology, and definition of the methods of surgery, radiation, and chemotherapy to give the reader a better understanding of the contents of the guidelines for these rare tumors. The first chapter gives an overview of the guidelines, including the basic policy of the guidelines. The second chapter discusses vulvar cancer, the third chapter discusses vaginal cancer, and the fourth chapter discusses vulvar Paget's disease and malignant melanoma. Each chapter includes clinical questions, recommendations, backgrounds, objectives, explanations, and references. The fifth chapter provides supplemental data for the drugs that are mentioned in the explanation of clinical questions. CONCLUSION: Overall, the objective of these guidelines is to clearly delineate the standard of care for vulvar and vaginal cancer with the goal of ensuring a high standard of care for all women diagnosed with these rare diseases.

Japan Society of Gynecologic Oncology guidelines 2015 for the treatment of ovarian cancer including primary peritoneal cancer and fallopian tube cancer.

The fourth edition of the Japan Society of Gynecologic Oncology guidelines for the treatment of ovarian cancer including primary peritoneal cancer and fallopian tube cancer was published in 2015. The guidelines contain seven chapters and six flow charts. The major changes in this new edition are as follows-(1) the format has been changed from reviews to clinical questions (CQ), and the guidelines for optimal clinical practice in Japan are now shown as 41 CQs and answers; (2) the 'flow charts' have been improved and placed near the beginning of the guidelines; (3) the 'basic points', including tumor staging, histological classification, surgical procedures, chemotherapy, and palliative care, are described before the chapter; (4) the FIGO surgical staging of ovarian cancer, fallopian tube cancer, and primary peritoneal cancer was revised in 2014 and the guideline has been revised accordingly to take the updated version of this classification into account; (5) the procedures for examination and management of hereditary breast and ovarian cancer are described; (6) information on molecular targeting therapy has been added; (7) guidelines for the treatment of recurrent cancer based on tumor markers alone are described, as well as guidelines for providing hormone replacement therapy after treatment.

Japan Society of Gynecologic Oncology guidelines 2013 for the treatment of uterine body neoplasms.

The third version of the Japan Society of Gynecologic Oncology guidelines for the treatment of uterine body neoplasms was published in 2013. The guidelines comprise nine chapters and nine algorithms. Each chapter includes a clinical question, recommendations, background, objectives, explanations, and references. This revision was intended to collect up-to-date international evidence. The highlights of this revision are to (1) newly specify costs and conflicts of interest; (2) describe the clinical significance of pelvic lymph node dissection and para-aortic lymphadenectomy, including variant histologic types; (3) describe more clearly the indications for laparoscopic surgery as the standard treatment; (4) provide guidelines for post-treatment hormone replacement therapy; (5) clearly differentiate treatment of advanced or recurrent cancer between the initial treatment and the treatment carried out after the primary operation; (6) collectively describe fertility-sparing therapy for both atypical endometrial hyperplasia and endometrioid adenocarcinoma (corresponding to G1) and newly describe relapse therapy after fertility-preserving treatment; and (7) newly describe the treatment of trophoblastic disease. Overall, the objective of these guidelines is to clearly delineate the standard of care for uterine body neoplasms in Japan with the goal of ensuring a high standard of care for all Japanese women diagnosed with uterine body neoplasms.

Japanese Society of Clinical Oncology clinical practice guidelines 2010 for antiemesis in oncology: executive summary.

The purpose of this article is to disseminate the standard of antiemetic therapy for Japanese clinical oncologists. On the basis of the Appraisal of Guidelines for Research and Evaluation II instrument, which reflects evidence-based clinical practice guidelines, a working group of the Japanese Society of Clinical Oncology (JSCO) reviewed clinical practice guidelines for antiemesis and performed a systematic review of evidence-based domestic practice guidelines for antiemetic therapy in Japan. In addition, because health-insurance systems in Japan are different from those in other countries, a consensus was reached regarding standard treatments for chemotherapy that induce nausea and vomiting. Current evidence was collected by use of MEDLINE, from materials from meetings of the American Society of Clinical Oncology National Comprehensive Cancer Network, and from European Society of Medical Oncology/Multinational Association of Supportive Care in Cancer guidelines for antiemesis. Initially, 21 clinical questions (CQ) were selected on the basis of CQs from other guidelines. Patients treated with highly emetic agents should receive a serotonin (5-hydroxytryptamine; 5HT3) receptor antagonist, dexamethasone, and a neurokinin 1 receptor antagonist. For patients with moderate emetic risk, 5HT3 receptor antagonists and dexamethasone were recommended, whereas for those receiving chemotherapy with low emetic risk dexamethasone only is recommended. Patients receiving high-emetic-risk radiation therapy should also receive a 5HT3 receptor antagonist. In this paper the 2010 JSCO clinical practice guidelines for antiemesis are presented in English; they reveal high concordance of Japanese medical circumstances with other antiemetic guidelines that are similarly based on evidence.

Japan Society of Gynecologic Oncology guidelines 2011 for the treatment of uterine cervical cancer.

The second edition of the Japan Society of Gynecologic Oncology guidelines for the treatment of uterine cervical cancer was published in 2011. The guidelines comprise eight chapters and five algorithms. They were prepared by consensus among the members of the Japan Society of Gynecologic Oncology Guidelines Formulation Committee and Evaluation Committee and are based on a careful review of the evidence obtained from the literature, health insurance system, and actual clinical settings in Japan. The highlights of the 2011 revision are (1) the recommended grades have been changed to five stages--A, B, C1, C2, and D; (2) the revisions are consistent with the new International Federation of Gynecology and Obstetrics staging system; (3) the roles are shared between the 'Japanese classification of cervical cancer' and the new guidelines; (4) clinical questions related to adenocarcinoma have been revised; and (5) a clinical question regarding cervical cancer in pregnant patients has been added. Each chapter includes a clinical question, recommendations, background, objectives, explanations, and references. Each recommendation is accompanied by a classification of recommendation categories. The objective of these guidelines is to update the standard treatment strategies for cervical cancer, thus eliminating unnecessary and insufficient treatment.

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. The relationships between cytological scores and clinicopathological factors or prognosis were investigated. RESULTS: The median cytological score was 6 (range 4-14); therefore, samples with scores of 4-5 were defined as having low scores, while those with scores of 6-14 were defined as high scores. The accuracy of the cytological diagnosis for grade 3 tumors in the high score group (8/10 patients, 80.0%) was significantly higher than that of the low score group (2/11 patients, 18.2%; p=0.009). Significant relationships between cytological scores and lymph node metastases or positive peritoneal cytology were observed (p=0.03 and 0.035, respectively). The overall survival rate was significantly worse in the high score group (30.0%) than the low score group (88.9%; p=0.02). CONCLUSIONS: Grade 3 endometrioid adenocarcinomas varied in cytological features; according to the scoring system used, high scores were associated with worse clinicopathological factors and poorer prognosis than low scores.

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. Primary outcomes were overall response rate (complete response [CR] + partial response [PR]), disease control rate (CR + PR + stable disease), and progression-free survival (PFS) in each group. Clinical response was evaluated every two or three cycles using the Response Evaluation Criteria in Solid Tumors criteria; CA125 analysis was not performed. RESULTS: The overall response rate was 21.1 % (PR, four cases) and 0 % (p = 0.10) in the CPT-11 and PLD groups, respectively, and the disease control rate was 73.7 and 45.5 % (p = 0.12), respectively. Median PFS was 25.3 (range 5.4-69.9) weeks and 12.7 (range 4.0-43.1) weeks in the CPT-11 and PLD groups, respectively; however, this difference was not statistically significant (p = 0.064). Major adverse events in the CPT-11 group were neutropenia, nausea, and diarrhea, whereas those in the PLD group included thrombocytopenia, anemia, stomatitis, and hand-foot syndrome. CONCLUSIONS: This retrospective study demonstrated comparable efficacy outcomes for CPT-11 and PLD. The overall response rate, disease control rate, and median PFS were more favorable in the CPT-11 group compared to the PLD group, although the difference was not significant. The adverse event profiles were different between groups. These results suggest that CPT-11 might be a feasible choice as single-agent salvage chemotherapy for platinum-resistant or -refractory recurrent epithelial ovarian and primary peritoneal carcinoma beside established regimen like PLD.

Effect of ursolic acid on MAPK in cyclin D1 signaling and RING-type E3 ligase (SCF E3s) in two endometrial cancer cell lines.

Cyclin D1 regulates G1 progression and is important in the development and proliferation of various human cancers. Cyclin D1 gene expression is activated by the Ras kinase cascade. Nuclear cyclin D1 levels are dependent on cytoplasmic degradation of cyclin D1 via ubiquitin-mediated proteolysis. We sought to determine whether the important MAPK signaling pathway, in the cyclin D1 cascade, including FBXW8, Cullin1, and the ubiquitination pathway mediated these effects. Ursolic acid (UA) treatment of SNG-2 cells, an endometrial cancer cell line, decreased cyclin D1, pERK1/2, FBXW8, and Cullin1 levels in a dose- and time-dependent manner. RING-type E3 ligase consists of CulIin1, Rbx, Skp1, and a member of the F-box protein family. In SNG-2, both dose- and time-dependent inhibition of Rbx 1 were observed following treatment with UA. Moreover, in HEC108 cells, another endometrial cancer cell line, UA treatment decreased cyclin D1, pERK1/2, and Cullin1 levels in a dose- and time-dependent manner and UA markedly inhibited FBXW8. Treatment of HEC108 cells moderately decreased Rbx1 in a dose- and-time-dependent fashion. In contrast, UA treatment increased ubiquitinated proteins in a dose- and time-dependent manner in both cell lines. RING-type E3 ligase accumulated in the cytoplasm following UA treatment of SNG-2cells. That in turn prevented cytoplasmic degradation of cyclin D1 via RING-type E3 (SCF E3s) ligase. In conclusion, our study found inhibition of the MAPK- cyclin D1 pathway and RING type E3 ligase (SCF E3s) in both endometrial cancer cell lines. Furthermore, CD36 was noted as a cell surface receptor for UA.

Mutations of the SYCP3 gene in women with recurrent pregnancy loss.

Aneuploidy, a chromosomal numerical abnormality in the conceptus or fetus, occurs in at least 5% of all pregnancies and is the leading cause of early pregnancy loss in humans. Accumulating evidence now suggests that the correct segregation of chromosomes is affected by events occurring in prophase during meiosis I. These events include homologous chromosome pairing, sister-chromatid cohesion, and meiotic recombination. In our current study, we show that mutations in SYCP3, a gene encoding an essential component of the synaptonemal complex that is central to the interaction of homologous chromosomes, are associated with recurrent pregnancy loss. Two out of 26 women with recurrent pregnancy loss of unknown cause were found to carry independent heterozygous nucleotide alterations in this gene, neither of which was present among a group of 150 fertile women. Analysis of transcripts from minigenes harboring each of these two mutations revealed that both affected normal splicing, possibly resulting in the production of C-terminally mutated proteins. The mutant proteins were found to interact with their wild-type counterpart in vitro and inhibit the normal fiber formation of the SYCP3 protein when coexpressed in a heterologous system. These data suggest that these mutations are likely to generate an aberrant synaptonemal complex in a dominant-negative manner and contribute to abnormal chromosomal behavior that might lead to recurrent miscarriage. Combined with the fact that similar mutations have been previously identified in two males with azoospermia, our current data suggest that sexual dimorphism in response to meiotic disruption occurs even in humans.

Asymptomatic synchronous quintuple primary cancers.

We encountered a 46-year-old woman with synchronous quintuple primary cancers. She did not present with any symptoms, and her tumors were discovered at a gynecological screening. She had clear cell adenocarcinoma of the right ovary, moderately differentiated endometrioid adenocarcinoma of the endometrium, moderately differentiated adenocarcinoma of the ascending colon, well-differentiated adenocarcinoma of the rectum, and poorly differentiated papillary adenocarcinoma of the left lung. A fluorodeoxyglucose-positron emission tomography and other imaging techniques were extremely useful for the diagnosis of multiple primary cancers. Moreover, MSH2 protein expression was absent in the tumors of the ovary, endometrium, ascending colon, and rectum, while the rectal cancer also lacked MLH1 protein. These findings suggested that an abnormality of DNA mismatch repair genes was responsible for carcinogenesis.

The effects of the selective cyclooxygenase-2 inhibitor on endometrial cytological findings in uterine endometrial cancer patients.

OBJECTIVE: We previously reported that oral administration of the selective cyclooxygenase-2 (COX-2) inhibitor etodolac results in antitumor effects in endometrial cancer tissue. Herein, we investigated whether these antitumor effects could be assessed using endometrial cytological findings. STUDY DESIGN: Etodolac (400 mg b.i.d. for 2 weeks) was administered preoperatively to 21 endometrial cancer patients: 16 had COX-2-positive disease and 5 had COX-2-negative disease. Twenty-one pairs of pre- and post-etodolac-treatment endometrial cytological samples were collected to review changes in the cytological features. RESULTS: In the COX-2-positive patients, nuclear atypia was slightly decreased in 3 of the 16 cases, while the mitotic index was decreased in all cases. Cellular overlapping and tumor cell cluster outlines were somewhat affected in 6 and 8 cases, respectively. Nuclear/cytoplasmic ratio, anisokaryosis and hyperchromasia were also reduced in 6, 4, and 2 cases, respectively; however, tumor diathesis and nucleoli features were unchanged. In contrast, endometrial cytological features did not appear to be affected in the 5 COX-2-negative patients. CONCLUSIONS: We conclude that the antitumor effects observed in endometrial cancer tissues following oral administration of etodolac are reflected in and can be easily assessed by evaluating endometrial cytological features.

New terminology for intrauterine endometrial samples: a group study by the Japanese Society of Clinical Cytology.

OBJECTIVE: To evaluate the sensitivity and specificity of endometrial cytology obtained by intrauterine sample using a descriptive reporting format for endometrial cytological diagnosis. STUDY DESIGN: 10,152 consecutive endometrial scrapings obtained in 13 different Japanese hospitals were analyzed. Cytological results were classified as 'negative for malignancy', 'atypical endometrial cells' (ATEC), 'endometrial hyperplasia', 'atypical endometrial hyperplasia' or 'malignant tumor'. ATEC was subclassified as 'ATEC, of undetermined significance' (ATEC-US) and 'ATEC, cannot exclude atypical endometrial hyperplasia or more' (ATEC-A). Cytological results were compared with the histological diagnosis as a gold standard. When the cytological result was 'negative for malignancy' and there was no subsequent histological examination, the case was considered a true negative when the endometrium was assessed as normal on transvaginal ultrasonography and there was no abnormal uterine bleeding. RESULTS: 1,083 cases in which histology was not performed, 557 cases of 'unsatisfactory specimen' and 76 cases of ATEC-US were excluded. In the remaining 8,436 cases, the sensitivity and specificity, positive predictive value and negative predictive value for detecting atypical endometrial hyperplasia or malignant tumors were 79.0 and 99.7, 92.9 and 98.9%, respectively. CONCLUSION: The current diagnostic standards for endometrial cytology in Japan were established. Specificity is satisfactory for excluding cancer or precancerous diseases.

Polymorphisms in the annexin A5 gene promoter in Japanese women with recurrent pregnancy loss.

Recent findings have raised the possibility that polymorphisms within the annexin A5 gene (ANXA5) promoter contribute to the etiology of recurrent pregnancy loss (RPL). In our present study, 243 Japanese women who had suffered more than three fetal losses and a group of 119 fertile controls were genotyped for four ANXA5 gene promoter single-nucleotide polymorphisms (SNPs; SNP1-4: g.-467G >A, g.-448A>C, g.-422T>C, g.-373G>A) previously reported to be associated with this disorder. An additional two SNPs located within the 5'-untranslated region of the ANXA5 (SNP5 and 6: g.-302T>G, g.-1C>T) were also evaluated. Our case--control study revealed that the minor allele was significantly more frequent in the RPL group than controls for all six of these SNPs, among which SNP5 showed the highest significance (P= 0.002). As with the M2 haplotype for SNP1-4 (A-C-C-A) for a western population in previous reports, a haplotype comprising all of the minor alleles for SNP1-6 (A-C-C-A-G-T), the third major haplotype in the Japanese population, showed a significantly higher frequency in our current RPL subjects than in controls (P= 0.025). In addition, the second major haplotype (G-A-T-G-G-C) was found to confer a significant risk of RPL (P= 0.036), implicating SNP5 as a major risk determinant for this disease. Our present findings support the hypothesis that genomic variations within the ANXA5 gene upstream region impact upon the disease susceptibility to RPL. Our data indicate that SNP5 is a novel risk factor for this disease in the Japanese population.

Comparative gene expression profiling of placentas from patients with severe pre-eclampsia and unexplained fetal growth restriction.

BACKGROUND: It has been well documented that pre-eclampsia and unexplained fetal growth restriction (FGR) have a common etiological background, but little is known about their linkage at the molecular level. The aim of this study was to further investigate the mechanisms underlying pre-eclampsia and unexplained FGR. METHODS: We analyzed differentially expressed genes in placental tissue from severe pre-eclamptic pregnancies (n = 8) and normotensive pregnancies with or (n = 8) without FGR (n = 8) using a microarray method. RESULTS: A subset of the FGR samples showed a high correlation coefficient overall in the microarray data from the pre-eclampsia samples. Many genes that are known to be up-regulated in pre-eclampsia are also up-regulated in FGR, including the anti-angiogenic factors, FLT1 and ENG, believed to be associated with the onset of maternal symptoms of pre-eclampsia. A total of 62 genes were found to be differentially expressed in both disorders. However, gene set enrichment analysis for these differentially expressed genes further revealed higher expression of TP53-downstream genes in pre-eclampsia compared with FGR. TP53-downstream apoptosis-related genes, such as BCL6 and BAX, were found to be significantly more up-regulated in pre-eclampsia than in FGR, although the caspases are expressed at equivalent levels. CONCLUSIONS: Our current data indicate a common pathophysiology for FGR and pre-eclampsia, leading to an up-regulation of placental anti-angiogenic factors. However, our findings also suggest that it may possibly be the excretion of these factors into the maternal circulation through the TP53-mediated early-stage apoptosis of trophoblasts that leads to the maternal symptoms of pre-eclampsia.

High prevalence of hypovitaminosis D in pregnant Japanese women with threatened premature delivery.

Serum 25-hydroxyvitamin D (25-OHD) concentrations are thought to accurately reflect vitamin D stores, and vitamin D deficiency causes secondary hyperparathyroidism, irreversible bone loss, and increased risk of fracture. Recent studies suggest that decrease of serum 25-OHD level in mothers could increase the risk of preeclampsia, cesarean section, and craniotabes. Furthermore, this deficiency may affect bone mass and the incidence of neuromuscular diseases of their children in the future. In the present study, the serum concentration of 25-OHD in 93 pregnant women after the 30th week of their gestation was determined by direct radioimmunoassay. Mean 25-OHD levels in spring, summer, fall, and winter were 14.3 ± 5.1, 15.7 ± 6.4, 13.7 ± 5.1, and 13.9 ± 4.2 ng/ml, respectively. Severe vitamin D deficiency (25-OHD < 10 ng/ml) was found in 10 of these 93 women. Overall, hypovitaminosis D, which was defined as serum 25-OHD concentration equal to or less than 20 ng/ml, was revealed in 85 mothers (89.5%). Serum 25-OHD levels were not associated with either intact parathyroid hormone or corrected calcium concentrations, but were negatively associated with serum type I collagen N-terminal telopeptide and bone-specific alkaline phosphatase in these subjects. Mothers with threatened premature delivery had significantly lower 25-OHD levels (11.2 ± 3.2 ng/ml) than those in mothers with normal delivery (15.6 ± 5.1 ng/ml). In conclusion, the present data suggest a high prevalence of hypovitaminosis D in perinatal pregnant Japanese women throughout the year, which seems to affect bone metabolism and to be associated with threatened premature delivery.

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. Excision repair cross-complementation group 1 protein expression was examined by immunohistochemistry in tumor tissues. The relationship between ERCC1 expression levels and clinicopathological factors (age, FIGO stage, histological grade, tumor size, vascular invasion, cervical stromal invasion, and lymph node metastases) and prognosis was evaluated. RESULTS: No significant differences between ERCC1 expression levels and clinicopathological factors were observed. The patients in the ERCC1 high-expression group (n = 7) experienced significantly worse disease-free survival than the patients in the ERCC1 low-expression group (n = 29; P = 0.005). Among the 25 patients who received cisplatin-based chemotherapy or chemoradiotherapy with cisplatin, those with high ERCC1 expression (n = 5) also experienced significantly worse disease-free survival than those with low ERCC1 expression (n = 20; P = 0.002). Moreover, univariate and multivariate analyses revealed that high ERCC1 expression was an independent prognostic factor in patients receiving cisplatin-based chemotherapy or chemoradiotherapy with cisplatin. CONCLUSIONS: This is the first analysis of the association between ERCC1 expression and clinical outcomes in patients with uterine cervical adenocarcinoma. High ERCC1 protein expression was revealed to be associated with worse disease-free survival in the patients who received adjuvant cisplatin-based chemotherapy or chemoradiotherapy with cisplatin and was shown to be an independent prognostic factor. Further evaluation with a larger number of patients is required to confirm these preliminary observations.

A case of primary alveolar soft part sarcoma of the uterine cervix and a review of the literature.

Alveolar soft part sarcoma (ASPS) that originates from the uterine cervix is extremely rare, with only thirteen cases reported. The participation of the ASPL-TFE3 chimeric gene, translocation (X; 17) (p11; q25), has been demonstrated in ASPS. Here, we report a case of cervical ASPS, along with a review of the literature. The patient, a 56-year-old woman, was referred for a 70 × 80 mm cervical tumor. She underwent a hysterectomy and bilateral salpingo-oophorectomy, and remained disease free for 66 months without adjuvant therapy. Pathological examination revealed features consistent with ASPS. In addition, the present case demonstrated strong positive nuclear staining for TFE3, and ASPL-TFE3 fusion gene type 1 was detected by RT-PCR. In a review of fourteen cases of this tumor (including the present case), the immunohistochemical expression patterns of myogenic or neuroendocrine markers were somewhat varied among cases. In all cases except for the present case, the patients were under 40 years of age, and the tumor sizes were under 5 cm. The prognosis of ASPS in the cervix was considerably better than that of ASPS in soft tissues. Complete resection with adequate margins is thought to be important, although the appropriate surgical method, including lymph node dissection, is uncertain. The role of chemotherapy or radiotherapy as adjuvant therapy has not been defined. Cervical ASPS is extremely rare, making case series the most viable option for understanding their natural history and for developing a treatment strategy, including an optimal surgical procedure and adjuvant therapy.

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. We encountered a pregnant woman aged 33 years who was diagnosed as having atypical carcinoid of the uterine cervix after radical surgery. Despite multidrug chemotherapy (paclitaxel + etoposide + cisplatin and irinotecan + carboplatin), the patient developed multiple organ metastases. Although there was no metastasis to the brain parenchyma or the spinal cord parenchyma, the patient also developed meningeal carcinomatosis. Whole-brain radiation therapy was performed, but was ineffective. The patient died at 19 months after her initial operation and 10 days after diagnosis of meningeal carcinomatosis. The presence of meningeal carcinomatosis was confirmed at autopsy.
