[Association of marital relationships with obstetrical history and physical and psychosocial factors of pregnant women in urban areas: A cross-sectional analysis from the perspective of adaptation to pregnancy].

Objectives　This study aimed to determine the association of marital relationships with pregnant women's obstetrical history, physical and psychosocial factors, and characteristics of women and husbands from the perspective of adaptation to pregnancy. Moreover, it sought to offer suggestions regarding support for couples during pregnancy in urban areas.Methods　We distributed self-reported questionnaires to pregnant women who participated in antenatal classes, organized by Public Interest Incorporated Foundation A, in four designated cities in the Kansai region of Japan. We investigated women's obstetrical history, physical and psychosocial factors, and characteristics of women and husbands using the Japanese Prenatal Self-Evaluation Questionnaire (Relationship with Husband) (J-PSEQ). Of the 778 women, 413 (53.1%) responded. After applying the exclusion criteria, 388 participants were eligible for analysis (valid response rate: 93.9%). Based on their J-PSEQ scores, participants were divided into two groups: poor marital relationship and normal or good marital relationship. Logistic regression analysis was performed to examine the factors related to the quality of marital relationships from the perspective of adaptation to pregnancy.Results　Based on the J-PSEQ scores, 93 (24.0%) participants were categorized into the poor marital relationship group, and 295 (76.0%) were categorized into the normal or good marital relationship group. For the poor marital relationship group, the logistic regression analysis showed that the odds ratios (confidence intervals) for "pregnancy after infertility treatment," "easily angered and irritated," and "husband's health: somewhat poor" were 2.54 (1.38-4.66), 3.55 (1.86-6.78), and 3.54 (1.06-11.87), respectively. Women who described household finances, husbands' working conditions, and lack of support to be the most stressful factors were more likely to have poor marital relationships. The factors associated with normal or good marital relationships included women experiencing physical discomfort, women not engaging in Satogaeri Shussan (staying at women's parents' homes before and after birth), husbands taking paternity leave after childbirth, and husbands having good health.Conclusions　This study revealed that the factors associated with poor marital relationships in terms of adaptation to pregnancy were pregnancy after infertility treatment, anger and irritation in women, and poor health of husbands. Healthcare professionals may need to focus more closely on supporting such couples in urban areas during pregnancy.

Regression of uterine cervical diffuse large B-cell lymphoma transformed from mucosa-associated lymphoid tissue lymphoma subsequent to Chlamydia trachomatis eradication.

A 37-year-old-woman was referred to our center after her uterine cervix health screening presented abnormal findings. We performed a biopsy of the uterine cervix to examine for cervical dysplasia, and diagnosed a diffuse large B-cell lymphoma transformed from mucosa-associated lymphoid tissue (MALT) lymphoma of the cervix. The patient presented with concurrent chlamydial cervicitis and received eradication therapy for Chlamydia trachomatis. Four months later, the CD20 positive abnormal lymphocyte disappeared and complete remission was achieved. MALT lymphoma is considered to correlate with infection and inflammation. Particularly, the relationship between gastric MALT lymphoma and Helicobacter pylori is well known. MALT lymphoma of the uterine cervix is rare, and its relationship with C.trachomatis infection is unknown. Further studies are warranted to investigate this association.

[A case and literature review of ovarian carcinosarcoma with long-term survival after repeated recurrences].

Ovarian carcinosarcoma is a rare and aggressive tumor with a poor prognosis. We report a case of ovarian carcinosarcoma and also review the literature. In 2000, a 63-year-old woman underwent optimal cytoreductive surgery for ovarian carcinosarcoma( International Federation of Gynaecology and Obstetrics[FIGO]stage III c[pT3cN0M0]). She received adjuvant chemotherapy with paclitaxel and carboplatin(TC). In 2005, a recurrent tumor was noted anterior to the sacrum. The patient had a complete response after 6 cycles of TC chemotherapy; however, a year later, the tumor recurred and was resected. In 2013, the tumor recurred adjacent to the right kidney and was surgically removed after a partial response to 3 cycles of TC chemotherapy. The pathologic findings included epithelial and non-epithelial components with histologic variation and differentiation; specifically, a leiomyosarcoma, cartilaginous tissues with cellular atypia, and a rhabdomyosarcoma were identified in specimens obtained during the first, second, and third surgical procedures, respectively. In keeping with the combination theory of histogenesis, the ovarian carcinosarcoma described herein may have originated from a monoclonal stem cell. The long survival of this patient is attributed to optimal cytoreduction during the primary operation, solitary recurrent tumors that were completely resected, and sensitivity to chemotherapy.

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.

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. The paclitaxel-resistant cell line OMC-2P was established from OMC-2 cells. Paclitaxel (1 µg/ml) with or without etodolac (10 µg/ml) was added to OMC-2 and OMC-2P cells, and COX-2 and MDR1 mRNA expression levels were examined. The concentration of prostaglandin E2 (PGE2) in the supernatant of each cell line was examined by enzyme-linked immunosorbent assay. The function of MDR1 was determined by intracellular accumulation of rhodamine 123 using flow cytometry, and the concentration of intracellular paclitaxel was determined by high-performance liquid chromatography. We found a positive relationship between COX-2 and MDR1 mRNA expression in endometrial cancer. Both COX-2 mRNA expression and PGE2 production were elevated in resistant OMC-2P cells when compared to non-resistant OMC-2 cells. Additionally, MDR1 mRNA expression was markedly upregulated in OMC-2P cells. In OMC-2 cells, COX-2 and MDR1 mRNA levels were significantly upregulated by paclitaxel treatment and downregulated by co-administration with etodolac. In OMC-2P cells, COX-2 mRNA expression was also significantly upregulated by paclitaxel treatment and tended to be downregulated by co-administration with etodolac. Moreover, co-administration of paclitaxel and etodolac suppressed the induction of MDR1 mRNA. Rhodamine 123 efflux was increased in OMC-2P cells when compared to the efflux in the OMC-2 cells and was increased in response to paclitaxel treatment. Co-administration of paclitaxel and etodolac in both cell lines resulted in decreased rhodamine 123 efflux. The actual concentration of intracellular paclitaxel in OMC-2P cells was significantly lower than that in OMC-2 cells treated with paclitaxel alone and was significantly increased after co-administration of paclitaxel and etodolac. These findings suggest that paclitaxel resistance may be associated with COX-2 and MDR1 expression in cancer cells. Co-administration of COX-2 inhibitors and paclitaxel may have a key role in modulating or overcoming paclitaxel resistance in endometrial cancers.

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.

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 effect of chemotherapy or radiotherapy on thymidine phosphorylase and dihydropyrimidine dehydrogenase expression in cancer of the uterine cervix.

OBJECTIVE: Levels of 5-FU metabolic or related enzymes, particularly thymidine phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD), have been investigated in various cancer types, including uterine cervical cancer. Intratumoral TP levels have been reported to increase in response to several chemotherapeutic agents or irradiation in both xenografts and clinical studies. In cervical cancer, however, only a few studies about changes in TP and DPD expression associated with cancer treatment have been published. We evaluated the effect of chemotherapy and/or irradiation on TP and DPD expression in cervical squamous cell carcinoma. STUDY DESIGN: Of 27 patients in this study, 12 patients underwent neoadjuvant chemotherapy consisting of nedaplatin, ifosfamide, and/or peplomycin followed by radical surgery, and 15 patients underwent radiotherapy (n=8) or chemoradiotherapy with nedaplatin (n=7) as initial treatment. Tumor specimens were obtained from biopsies acquired before treatment and after administration of chemotherapy (2 weeks after the first and second cycles), and after irradiation with 10 Gy, 20 Gy, and 30 Gy. These specimens were used to measure TP and DPD levels by ELISA. RESULTS: In the 12 patients who received neoadjuvant chemotherapy, intratumoral TP and DPD levels did not change. In contrast, in the 15 patients who underwent radiotherapy or chemoradiotherapy with nedaplatin, TP or DPD expression appeared to be slightly increased or decreased, respectively, after irradiation with 20 Gy, and consequently the TP/DPD ratio was significantly higher after irradiation with 20 Gy than before irradiation. CONCLUSIONS: These results suggest a clinical advantage of chemoradiotherapy with capecitabine or doxyfluridine over radiotherapy alone via the elevation of the TP/DPD ratio in cervical squamous cell carcinoma. However, no advantage of combination chemotherapy with these 5-FU derivatives was demonstrated. Therefore, further evaluation with a larger number of patients or with other chemotherapeutic agents is required to confirm these observations.

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.

Detection of M2 macrophages and colony-stimulating factor 1 expression in serous and mucinous ovarian epithelial tumors.

Tumor-associated macrophages (TAM) are known to possess the immunosuppressive M2 macrophage phenotype. They contribute to tumor growth, invasion, and metastasis by producing various mediators. Macrophages, especially M2 polarized macrophages, preferentially express CD163 and CD204, but few studies have investigated macrophage phenotypes in human ovarian tumors. The purpose of the present study was therefore to present results on macrophage differentiation in human ovarian serous and mucinous epithelial tumors. The method focused on immunostaining of paraffin-embedded tumor samples. Almost all macrophages infiltrating tumor tissues expressed CD163 and CD204, indicating the phenotypic shift toward M2 macrophage. The numbers of CD68-positive macrophages as well as of CD163- and CD204-positive macrophages in borderline and malignant tumors were significantly higher than in benign tumors. They correlated well with histological gradient of malignancy. Macrophage colony-stimulating factor (also known as colony-stimulating factor; CSF-1), which is one of the cytokines considered to induce TAM to polarize toward an M2 phenotype, was then evaluated. CSF-1 expression in malignant tumor cells was significantly higher than that in benign tumor cells and correlated with histological malignancy. These results suggest that CSF-1 derived from tumor tissues induces macrophages to shift toward the M2 phenotype, which is considered to promote tumor growth.

AM-3K, an anti-macrophage antibody, recognizes CD163, a molecule associated with an anti-inflammatory macrophage phenotype.

CD163 is a member of the scavenger receptor cysteine-rich superfamily restricted to the monocyte/macrophage lineage and is thought to be a useful marker for anti-inflammatory or alternatively activated macrophages. In this study we used mass spectrometric analysis to determine that the antigen recognized by the antibody AM-3K, which we previously generated as a tissue macrophage-specific monoclonal antibody, was CD163. An anti-inflammatory subtype of macrophages stimulated by dexamethasone or interleukin-10 showed strong reactivity for AM-3K and increased expression of CD163 mRNA. Immunohistochemical staining of routinely processed pathological specimens revealed that AM-3K recognized a specialized subpopulation of macrophages. In granulomatous diseases such as tuberculosis, sarcoidosis, or foreign body reactions, tissue macrophages around granulomas, but not component cells of the granulomas such as epithelioid cells and multinucleated giant cells, showed positive staining for AM-3K. In atherosclerotic lesions, scattered macrophages in diffuse intimal lesions were strongly positive for AM-3K, whereas foamy macrophages in atheromatous plaques demonstrated only weak staining. We therefore suggest that, in routine pathological specimens, AM-3K is a useful marker for anti-inflammatory macrophages because these cells can be distinguished from inflammatory or classically activated macrophages. Because AM-3K cross-reacts with macrophage subpopulations in different animal species including rats, guinea pigs, rabbits, cats, dogs, goats, pigs, bovine species, horses, monkeys, and cetaceans, it will have wide application for detection of CD163 in various animals.
