RESUMO

Reproduction in mammals includes two general categories of behaviors: mating and parenting. Historically and cross-culturally, men invest more than women in mating; women invest more than men in parenting. Sex differences in attention and attitude toward mating and parenting stimuli have rarely been assessed together despite theoretical interest. To evaluate these differences simultaneously in a naturalistic setting, 582 study participants (459 women, 123 men) were presented with sexual and infant images, online in the privacy of their home, at three time periods spanning several weeks for a more reliable result. Attention was measured by covertly recording viewing time of images using Qualtrics software, and attitude was measured via self-report after each viewing session. Men reported a more positive attitude than women toward the sexual images; women reported a more positive attitude than men toward the infant images. Women viewed the infant images marginally longer than did men, and the infant-to-sexual viewing ratio was larger for women. The sexual-to-infant viewing ratio was larger for men than for women. Unexpectedly, both genders viewed the sexual images longer than the infant images, with no significant gender difference in the sexual image viewing time. The results suggest that women and men may give equal attention to visual sexual stimuli despite self-reported sex differences in interest. The possibly underestimated valence of visual sexual stimuli for women is discussed.

RESUMO

Summary The S3-guideline on endometrial cancer, first published in April 2018, was reviewed in its entirety between April 2020 and January 2022 and updated. The review was carried out at the request of German Cancer Aid as part of the Oncology Guidelines Program and the lead coordinators were the German Society for Gynecology and Obstetrics (DGGG), the Gynecology Oncology Working Group (AGO) of the German Cancer Society (DKG) and the German Cancer Aid (DKH). The guideline update was based on a systematic search and assessment of the literature published between 2016 and 2020. All statements, recommendations and background texts were reviewed and either confirmed or amended. New statements and recommendations were included where necessary. Aim The use of evidence-based risk-adapted therapies to treat women with endometrial cancer of low risk prevents unnecessarily radical surgery and avoids non-beneficial adjuvant radiation therapy and/or chemotherapy. For women with endometrial cancer and a high risk of recurrence, the guideline defines the optimum level of radical surgery and indicates whether chemotherapy and/or adjuvant radiation therapy is necessary. This should improve the survival rates and quality of life of these patients. The S3-guideline on endometrial cancer and the quality indicators based on the guideline aim to provide the basis for the work of certified gynecological cancer centers. Methods The guideline was first compiled in 2018 in accordance with the requirements for S3-level guidelines and was updated in 2022. The update included an adaptation of the source guidelines identified using the German Instrument for Methodological Guideline Appraisal (DELBI). The update also used evidence reviews which were created based on selected literature obtained from systematic searches in selected literature databases using the PICO process. The Clinical Guidelines Service Group was tasked with carrying out a systematic search and assessment of the literature. Their results were used by interdisciplinary working groups as a basis for developing suggestions for recommendations and statements which were then modified during structured online consensus conferences and/or additionally amended online using the DELPHI process to achieve a consensus. Recommendations Part 1 of this short version of the guideline provides recommendations on epidemiology, screening, diagnosis, and hereditary factors. The epidemiology of endometrial cancer and the risk factors for developing endometrial cancer are presented. The options for screening and the methods used to diagnose endometrial cancer are outlined. Recommendations are given for the prevention, diagnosis, and therapy of hereditary forms of endometrial cancer. The use of geriatric assessment is considered and existing structures of care are presented.

RESUMO

Purpose The aim was to develop and update a guideline which would improve the quality of care offered to women with gestational and non-gestational trophoblastic disease, a group of diseases characterized by their rarity and biological heterogeneity. Methods In accordance with the method used to compile S2k-guidelines, the guideline authors carried out a search of the literature (MEDLINE) for the period 1/2020 to 12/2021 and evaluated the recent literature. No key questions were formulated. No structured literature search with methodical evaluation and assessment of the level of evidence was carried out. The text of the precursor version of the guideline from 2019 was updated based on the most recent literature, and new statements and recommendations were drafted. Recommendations The updated guideline contains recommendations for the diagnosis and therapy of women with hydatidiform mole (partial and complete moles), gestational trophoblastic neoplasia after pregnancy or without prior pregnancy, persistent trophoblastic disease after molar pregnancy, invasive moles, choriocarcinoma, placental site nodules, placental site trophoblastic tumor, hyperplasia at the implantation site und epithelioid trophoblastic tumor. Separate chapters cover the determination and assessment of human chorionic gonadotropin (hCG), histopathological evaluation of specimens, and the appropriate molecular pathological and immunohistochemical diagnostic procedures. Separate chapters on immunotherapy, surgical therapy, multiple pregnancies with simultaneous trophoblastic disease, and pregnancy after trophoblastic disease were formulated, and the corresponding recommendations agreed upon.

RESUMO

The publication of two large randomized studies - the ENGOT-EN-6-NSGO/GOG-3031/RUBY trial and the NRG-GY018 trial - which investigated combining chemotherapy with immunotherapy to treat patients with primary advanced or recurrent endometrial cancer (EC) has transformed the clinical study landscape in terms of first-line therapy for affected patients and has set a new standard of therapy. In the ENGOT-EN-6-NSGO/GOG-3031/RUBY trial, the addition of dostarlimab to standard chemotherapy with carboplatin and paclitaxel resulted in a significant and clinically relevant improvement of progression-free survival and overall survival in the overall population, a significant and clinically relevant improvement of progression-free survival and overall survival in the subgroup with dMMR/MSI-high tumors, and a significant and clinically relevant improvement of progression-free survival in the subgroup with pMMR/MSI-low tumors. In the NRG-GY018 trial, the addition of pembrolizumab to standard chemotherapy with carboplatin and paclitaxel resulted in a significant and clinically relevant improvement of progression-free survival in the group with dMMR tumors, and a significant and clinically relevant improvement of progression-free survival in the group with pMMR tumors. As expected, the effect in both trials was much more pronounced in the group of patients with dMMR/MSI-high tumors. According to the assessment of the Uterus Organ Commission of the AGO, all patients with dMMR/MSI-high tumors should receive chemoimmunotherapy and all patients with pMMR/MSI-low tumors who meet the inclusion criteria of the two trials discussed here may have chemoimmunotherapy. For dostarlimab this means: patients with EC recurrence who will not undergo surgery or radiotherapy, patients with stage IIIA, IIIB or IIIC1 disease and a measurable lesion postoperatively, patients with stage IIIA, IIIB or IIIC1 disease with histological findings of serous EC, clear-cell EC or carcinosarcoma with or without a measurable lesion postoperatively, and patients with stage IIIC2 or IV disease with or without a measurable lesion postoperatively. For pembrolizumab this means: patients with EC recurrence (except carcinosarcoma) who will not undergo surgery or radiotherapy, and patients with stage III or IVA disease (except carcinosarcoma) and a measurable lesion postoperatively or with stage IVB disease with or without a measurable lesion.

RESUMO

Beliefs about which sex lies more or is better at lying can have subtle but widespread effects on human interactions, yet little is known about such beliefs. In Study 1, an American sample of participants (N = 407, ages 18-64) completed a 12-item survey on perceptions of sex differences in deception. In Study 2, a Korean sample (N = 197, ages 19-58) completed the same survey. Men from both cultures and Korean women perceived no difference regarding which sex tells more white (i.e., relatively harmless or low-stakes) lies. American women perceived that women tell more white lies. Women from both cultures and American men perceived that men tell a greater number of serious (i.e., nonwhite or high-stakes) lies. Korean men perceived no difference regarding which sex tells a greater number of serious lies. Both sexes from both countries reported a perception that (1) men are more likely to lie about height, income, and sexual infidelity, (2) women are more likely to lie about weight and age, and (3) women are better at lying. The findings were mixed regarding perceptions about emotional infidelity. Results are interpreted in light of sex-different challenges to mating and parenting.

RESUMO

PURPOSE AND OBJECTIVES: Although food insecurity is associated with poor dietary intake and risk of chronic disease, few studies have demonstrated the effectiveness of diabetes prevention interventions delivered through food banks. Food banks serve vulnerable communities. The purpose of this pilot project was to assess the effectiveness of a food bank-delivered intervention aimed at improving food security and reducing risk factors for type 2 diabetes among at-risk clients. INTERVENTION APPROACH: We screened adult English- and Spanish-speaking food bank clients for type 2 diabetes risk at 12 community food distribution sites in Alameda County, California. Screening and enrollment for a pilot intervention took place from November 2017 to March 2018. Intervention components were delivered from November 2017 through March 2019. The intervention included monthly diabetes-appropriate food packages, text-based health education, and referrals to health care. EVALUATION METHODS: Food bank staff members administered surveys to participants at baseline, 6 months (midpoint), and 12 months (postintervention); participants self-reported all responses. Primary outcomes assessed were food security status, dietary intake, health-related behaviors, and body mass index (BMI). Information on demographic characteristics, food pantry access, health care use, and symptoms of depression was also collected. RESULTS: We screened 462 food bank clients for eligibility. Of the 299 who were eligible, 244 enrolled; 90.6% were female, 80.1% were Hispanic, and 49.1% had an annual household income less than $20,000. At baseline, 68.8% of participants had low or very low food security. At midpoint, participants had significant improvements in food security status, dietary intake, physical activity, health status, and depression scores. Mean BMI did not change. IMPLICATIONS FOR PUBLIC HEALTH: This intervention demonstrated that food banks can effectively screen clients at high risk for diabetes and improve household food security and other risk factors for diabetes. Food banks may be an important and strategic partner for health care systems or community-based organizations working to prevent diabetes in food-insecure populations.

RESUMO

Summary The first German interdisciplinary S3-guideline on the diagnosis, therapy and follow-up of patients with endometrial cancer was published in April 2018. Funded by German Cancer Aid as part of an Oncology Guidelines Program, the lead coordinators of the guideline were the German Society of Gynecology and Obstetrics (DGGG) and the Gynecological Oncology Working Group (AGO) of the German Cancer Society (DKG). Purpose Using evidence-based, risk-adapted therapy to treat low-risk women with endometrial cancer avoids unnecessarily radical surgery and non-useful adjuvant radiotherapy and/or chemotherapy. This can significantly reduce therapy-induced morbidity and improve the patient's quality of life as well as avoiding unnecessary costs. For women with endometrial cancer and a high risk of recurrence, the guideline defines the optimal extent of surgical radicality together with the appropriate chemotherapy and/or adjuvant radiotherapy if required. An evidence-based optimal use of different therapeutic modalities should improve the survival rates and quality of life of these patients. This S3-guideline on endometrial cancer is intended as a basis for certified gynecological cancer centers. The aim is that the quality indicators established in this guideline will be incorporated in the certification processes of these centers. Methods The guideline was compiled in accordance with the requirements for S3-level guidelines. This includes, in the first instance, the adaptation of source guidelines selected using the DELBI instrument for appraising guidelines. Other consulted sources included reviews of evidence, which were compiled from literature selected during systematic searches of literature databases using the PICO scheme. In addition, an external biostatistics institute was commissioned to carry out a systematic search and assessment of the literature for one part of the guideline. Identified materials were used by the interdisciplinary working groups to develop suggestions for Recommendations and Statements, which were then subsequently modified during structured consensus conferences and/or additionally amended online using the DELPHI method, with consent between members achieved online. The guideline report is freely available online. Recommendations Part 2 of this short version of the guideline presents recommendations for the therapy of endometrial cancer including precancers and early endometrial cancer as well as recommendations on palliative medicine, psycho-oncology, rehabilitation, patient information and healthcare facilities to treat endometrial cancer. The management of precancers of early endometrial precancerous conditions including fertility-preserving strategies is presented. The concept used for surgical primary therapy of endometrial cancer is described. Radiotherapy and adjuvant medical therapy to treat endometrial cancer and uterine carcinosarcomas are described. Recommendations are given for the follow-up care of endometrial cancer, recurrence and metastasis. Palliative medicine, psycho-oncology including psychosocial care, and patient information and rehabilitation are presented. Finally, the care algorithm and quality assurance steps for the diagnosis, therapy and follow-up of patients with endometrial cancer are outlined.

RESUMO

PURPOSE: The available literature on the treatment options for recurrent or metastatic endometrial cancer (EC) is full of controversies. Therefore, we explore the results of the AGO pattern of care studies from the years 2013, 2009 and 2006. METHODS: A questionnaire was developed and sent to all 682 German gynecological departments in 2013 (775 in 2009, 500 in 2006, respectively). The results of the questionnaires were compared with each other using Fisher's exact test. RESULTS: Responses were available in 40.0 % in 2013, 33.3 % in 2009 and 35.8 % in 2006. In 2013 the most preferred endocrine drug was progestin (79.8 %), followed by tamoxifen (42.8 %), aromatase inhibitor (19.8 %), fulvestrant (16.3 %) and a combination (3.9 %) (p < 0.001). 65.3, 59.8, 51.7 and 38.2 % of the participants used platinum, taxane, a combination of cytostatic drugs, anthracycline in metastatic EC, respectively (p = 0.215). 96.2, 92.7, 49.8 and 60.9 % of the participants performed an operation, radiotherapy, endocrine therapy and chemotherapy in 2013 because of a local recurrence, respectively (p < 0.001). Compared to 2009 and 2006 these rates remained stable (no p value <0.05). Because of a distant metastasis 50.4, 64.2, 78.5 and 90.8 % of the participants performed an operation, radiotherapy, endocrine therapy and chemotherapy in 2013, respectively (p < 0.001). Compared to 2009 and 2006 more participants performed an operation or radiotherapy and less an endocrine treatment. CONCLUSIONS: Whereas progestin was the favorite drug, the participants of this study did not prefer a specific cytostatic drug for metastatic EC in 2013. This might have reflected the available literature, which did not provide a real standard of care.

RESUMO

PURPOSE: In 2013, 2009 and 2006, the Arbeitsgemeinschaft Gynäkologische Onkologie evaluated the therapeutic approaches for endometrial carcinoma and the adherence to their guideline in Germany. Here, the adjuvant treatment decisions were presented. METHODS: A questionnaire was developed and sent to all 682 German gynecological departments in 2013 (775 in 2009 and 500 in 2006, respectively). The results of the questionnaires were compared with the recommendations of the guideline and with each other using Fisher's exact test. RESULTS: Responses were available in 40.0 % in 2013, 33.3 % in 2009 and 35.8 % in 2006. Participants recommended external beam radiotherapy (EBRT) in 13 out of 16 requested stages and vaginal brachytherapy (VBT) in only 10 out of 16 requested stages as suggested by the guideline. Comparing the results of 2013 with 2009, less participants used EBRT and VBT in 7 out of 16 and in 6 out of 16 requested stages, respectively. Conversely, more participants offered adjuvant chemotherapy (CT) in 2013 (90.4 %) compared to 61.9 % in 2009 (p < 0.001) and 48.8 % in 2006 (p < 0.001), respectively. However, the stage-adjusted recommendations of CT were not in line with the guideline in 11 out of 15 requested stages. In total, 77.3 % of the participants use a multiple drug schedule with a platinum and a taxane compound. CONCLUSIONS: The results suggest non-adherence to the guideline concerning the stage-adjusted use of VBT and CT in endometrial carcinoma. These findings emphasize great uncertainties and the need of more clarifying trials. Furthermore, a shift from radiotherapy toward CT is observable.

RESUMO

PURPOSE: In 2013, 2009, and 2006, the Arbeitsgemeinschaft Gynäkologische Onkologie evaluated the therapeutic approaches and the adherence to their guidelines for endometrial carcinoma (EC) in Germany. Here, we present the results concerning the surgical procedures. METHODS: A questionnaire was developed and sent to 682 German gynecological departments in 2013 (775 in 2009 and 500 in 2006). The results were compared with the recommendations of the guideline and with each other. RESULTS: Responses were available in 40.0 % in 2013, 33.3 % in 2009, and 35.8 % in 2006, respectively. Pelvic lymphadenectomy (LAN) was performed in accordance with the guidelines with some exceptions in 2013, 2009, and 2006, whereas paraaortic LAN was performed in accordance with the guideline only in 2009. Histological high-risk subtypes of EC received pelvic and paraaortic LAN in 2013, 2009, and 2006 in accordance with the guidelines with small exceptions. LAN for Patients, who were postoperatively upstaged or upgraded, was not conducted in accordance with the guidelines in 2013, 2009, and 2006. In 2013, 84.6 % of the participants offered the laparoscopic approach (LSA) for hysterectomy and bilateral salpingo-oophorectomy, 63.3 % for pelvic LAN, and 49.1 % for paraaortic LAN, respectively. More participants offered the LSA in 2013 compared to 2009 and 2006 (p values <0.014). CONCLUSIONS: The paraaortic LAN, the LSA as well as the second operation on patients who had postoperatively been upstaged were not conducted in accordance with the guideline [CORRECTED]. Improvements concerning surgical treatment are possible and might lead to higher survival rates and a reduction of morbidity in patients with EC in Germany.

RESUMO

OBJECTIVE: In 2009 and 2006, the Arbeitsgemeinschaft Gynäkologische Onkologie evaluated therapeutic approaches for endometrial carcinoma (EC) in Germany. METHODS AND MATERIALS: A questionnaire was developed and sent to 775 German gynecologic departments in 2009 (500 in 2006). The results of the questionnaires were compared with each other and with the recommendations of the Arbeitsgemeinschaft Gynäkologische Onkologie's guideline. Subgroup analyses were performed, dividing the participating centers into small and large centers and into centers with less and more experience with EC. RESULTS: Responses were available in 33.3% in 2009 and 35.8% in 2006. Comparing 2009 with 2006, it became apparent that peritoneal washing cytology was performed in 94.6% versus 86.9% (P = 0.008), pelvic lymphadenectomy (LAN) in 98.3% versus 95.3%, and paraaortic LAN in 90.2% versus 73.8% (P < 0.001) for endometrioid EC, and LAN for histologic high-risk subtypes of EC in 99.6% versus 94.2% (P = 0.001), respectively. In 2009, all these criteria met the recommendation of the guidelines. Reoperation for LAN after postoperative upstaging was performed in 66.1% versus 50.6% (P = 0.002), and adjuvant systemic treatment with chemotherapy and endocrine therapy was performed in 63.7% versus 48.8% (P = 0.003) and 25.7% versus 15.4% (P = 0.014), respectively. This showed nonadherence to the guidelines. Laparoscopic approach was performed in 30.4% versus 19.7% (P = 0.014) of the participating centers, respectively. In subgroup analysis, laparoscopic approach showed a significant difference between small centers (11.5%) and large centers (27.3%) in 2006 (P = 0.012). CONCLUSIONS: German hospitals increasingly follow the guidelines concerning LAN and peritoneal washing cytology. However, recommendations concerning reoperating in upstaged patients and adjuvant treatment decisions do not meet the guidelines, thus underlining great uncertainties in this field of gynecologic oncology.

RESUMO

Metastasis from primary tumors remains a major problem for tumor therapy. In the search for markers of metastasis and more effective therapies, the tumor metabolome is relevant because of its importance to the malignant phenotype and metastatic capacity of tumor cells. Altered choline metabolism is a hallmark of cancer. More specifically, a decreased glycerophosphocholine (GPC) to phosphocholine (PC) ratio was reported in breast, ovarian, and prostate cancers. Improved strategies to exploit this altered choline metabolism are therefore required. However, the critical enzyme cleaving GPC to produce choline, the initial step in the pathway controlling the GPC/PC ratio, remained unknown. In the present work, we have identified the enzyme, here named EDI3 (endometrial differential 3). Purified recombinant EDI3 protein cleaves GPC to form glycerol-3-phosphate and choline. Silencing EDI3 in MCF-7 cells decreased this enzymatic activity, increased the intracellular GPC/PC ratio, and decreased downstream lipid metabolites. Downregulating EDI3 activity inhibited cell migration via disruption of the PKCα signaling pathway, with stable overexpression of EDI3 showing the opposite effect. EDI3 was originally identified in our screening study comparing mRNA levels in metastasizing and nonmetastasizing endometrial carcinomas. Both Kaplan-Meier and multivariate analyses revealed a negative association between high EDI3 expression and relapse-free survival time in both endometrial (P < 0.001) and ovarian (P = 0.029) cancers. Overall, we have identified EDI3, a key enzyme controlling GPC and choline metabolism. Because inhibition of EDI3 activity corrects the GPC/PC ratio and decreases the migration capacity of tumor cells, it represents a possible target for therapeutic intervention.

RESUMO

Because of wide disparities in college students' math knowledge-that is, their math achievement-studies of cognitive processing in math tasks also need to assess their individual level of math achievement. For many research settings, however, using existing math achievement tests is either too costly or too time consuming. To solve this dilemma, we present three brief tests of math achievement here, two drawn from the Wide Range Achievement Test and one composed of noncopyrighted items. All three correlated substantially with the full achievement test and with math anxiety, our original focus, and all show acceptable to excellent reliability. When lengthy testing is not feasible, one of these brief tests can be substituted.

RESUMO

PURPOSE: Epithelial cell adhesion molecule (Ep-CAM) recently received increased attention not only as a prognostic factor in breast cancer but also as a potential target for immunotherapy. We examined Ep-CAM expression in 402 consecutive node-negative breast cancer patients with long-term follow-up not treated in the adjuvant setting. EXPERIMENTAL DESIGN: Ep-CAM expression was evaluated by immunostaining. Its prognostic effect was estimated relative to overexpression/amplification of HER-2, histologic grade, tumor size, age, and hormone receptor expression. RESULTS: Ep-CAM status was positive in 106 (26.4%) patients. In multivariate analysis, Ep-CAM status was associated with disease-free survival independent of age, pT stage, histologic grade, estrogen receptor (ER), progesterone receptor (PR), as well as HER2 status (P = 0.028; hazard ratio, 1.60; 95% confidence interval, 1.05-2.44). Recently, so-called triple-negative (HER-2, ER, and PR) breast cancer has received increased attention. We noticed a similar association of Ep-CAM with disease-free survival in the triple-negative group as for the entire cohort. CONCLUSION: In this study of untreated breast cancer patients, Ep-CAM overexpression was associated with poor survival in the entire cohort and in the subgroup of triple-negative breast cancer. This suggests that Ep-CAM may be a well-suited target for specific therapies particularly in HER-2-, ER-, and PR-negative tumors.

RESUMO

Estrogen receptor (ER) expression and proliferative activity are established prognostic factors in breast cancer. In a search for additional prognostic motifs, we analyzed the gene expression patterns of 200 tumors of patients who were not treated by systemic therapy after surgery using a discovery approach. After performing hierarchical cluster analysis, we identified coregulated genes related to the biological process of proliferation, steroid hormone receptor expression, as well as B-cell and T-cell infiltration. We calculated metagenes as a surrogate for all genes contained within a particular cluster and visualized the relative expression in relation to time to metastasis with principal component analysis. Distinct patterns led to the hypothesis of a prognostic role of the immune system in tumors with high expression of proliferation-associated genes. In multivariate Cox regression analysis, the proliferation metagene showed a significant association with metastasis-free survival of the whole discovery cohort [hazard ratio (HR), 2.20; 95% confidence interval (95% CI), 1.40-3.46]. The B-cell metagene showed additional independent prognostic information in carcinomas with high proliferative activity (HR, 0.66; 95% CI, 0.46-0.97). A prognostic influence of the B-cell metagene was independently confirmed by multivariate analysis in a first validation cohort enriched for high-grade tumors (n = 286; HR, 0.78; 95% CI, 0.62-0.98) and a second validation cohort enriched for younger patients (n = 302; HR, 0.83; 95% CI, 0.7-0.97). Thus, we could show in three cohorts of untreated, node-negative breast cancer patients that the humoral immune system plays a pivotal role in metastasis-free survival of carcinomas of the breast.

RESUMO

OBJECTIVE: The results obtained using plastic surgery reconstruction in 207 patients with a primary or recurrent vulvar carcinoma were analyzed with regard to the surgical procedures applied, pre-treatment and post-operative findings, along with the long-term oncological disease course. STUDY DESIGN: Standardized data concerning the surgical procedures applied and clinical factors were collected in a databank and statistically analyzed. RESULTS: The flaps employed were termed either 'local' (cutaneous or fasciocutaneous; n=84) or 'regional' (myocutaneous, n=123). For local flaps, the rate of secondary healing was 31%, dropping to 20% for regional flaps. Such healing disturbances often affected the donor region and did not lead to lasting clinical problems such as stenosis or distortion. Severe disturbances of wound healing (loss of more than 10%) were not observed in local flaps, whereas such problems were encountered in 5.9% of regional flaps. Gluteal thigh flaps were most frequently applied and were also the most successful type of myocutaneous reconstruction. Therapy was selected on an individual basis according to tumor status. CONCLUSION: Plastic surgery reconstruction broadens the range of operative therapies available for the treatment of vulvar carcinomas, especially those at an advanced stage or recurrent tumors, and leads to a favorable oncological disease course as well as improved cosmetic results.

RESUMO

BACKGROUND: HER3 (erbB-3) is a member of the epidermal growth factor receptor (EGFR) family. After dimerization with other members of the EGFR family several signal transduction cascades can be activated, including phosphoinosite 3'-kinase (PI3-K)/Akt and extracellular signal-regulated kinase (ERK1/2). Here, we studied a possible association between HER3 expression and prognosis in patients with ovarian cancer. METHODS: Tumor tissue of 116 consecutive patients diagnosed with primary epithelial ovarian cancer between 1986 and 1995 was analyzed immunohistochemically for HER3 expression. A possible influence of HER3 expression on survival was studied by multivariate Cox regression adjusting for established clinical prognostic factors. RESULTS: A positive HER3 expression was observed in 53.4% of the patients. HER3 expression was associated with decreased survival in proportional hazard modeling, including the International Federation of Gynecology and Obstetrics (FIGO) stage, histologic grade and type, residual disease, and age. After likelihood ratio forward as well as backward selection, only HER3 expression (hazard ratio, 1.71; 95% CI, 1.10 to 2.67; P = .018), FIGO stage (hazard ratio, 4.78; 95% CI, 1.89 to 12.08; P = .001), residual tumor (hazard ratio, 2.69; 95% CI, 1.40 to 5.17; P = .003), and age (hazard ratio, 2.06; 95% CI, 1.17 to 3.65; P = .013) were found to be significant. Kaplan-Meier plots demonstrated a clear influence of HER3 expression on survival time. Median survival time was 3.31 years (95% CI, 1.93 to 4.68) for patients with low HER3 expression, compared with only 1.80 years (95% CI, 0.83 to 2.78) for patients with HER3 overexpression (log-rank test P = .0034). CONCLUSION: HER3 may represent a new prognostic factor in primary epithelial ovarian cancer. Pending validation, exploration of therapeutic strategies to block HER3 could be warranted.

RESUMO

OBJECTIVE: The success of various surgical interventions in 201 cases with recurrent vulvar carcinoma was examined in the light of patients' pretreatment, surgical therapy, plastic reconstruction, and postoperative disease course. STUDY DESIGN: A databank of standardized clinical data was analyzed using statistical procedures. RESULTS: Therapy was selected on an individual basis according to tumor status. Recurrence at a site distant from the primary tumor, particularly in the inguinal region, indicated a markedly unfavorable prognosis. In contrast, tumors recurring locally did not exhibit any significant differences. Plastic surgery reconstruction led to improvements with respect to operability, wound healing, and survival. CONCLUSION: Individualized reconstructive surgery of the vulva leads to good results in patients with recurrent vulvar cancer. To an even greater extent than is the case for primary therapy, plastic surgery enlarges the spectrum of feasible surgical alternatives so that a more favorable oncological outcome and excellent cosmetic results may be expected.

RESUMO

In addition to the loss of function, mutant p53 can possess a dominant-negative effect on wild-type p53 and may also exert gain-of-function activity. It is not clear whether the functional status of p53 mutation contributes to differences in outcome in endometrial cancer. We collected a total of 92 RNA samples of high quality from endometrial cancer tissues, and the samples were subjected to yeast functional assay and sequencing for p53 mutations. The detected mutant p53 genes were further investigated for their dominant-negative activity using a yeast-based transdominance assay. p53 mutation was found in 24 out of 92 (26.1%) tumors, of which 10 exhibited no dominant-negative activity (recessive mutation) and 14 showed dominant-negative activity. Dominant-negative p53 mutation was related to advanced stages (p = 0.01), nonendometrioid type tumors (p = 0.01) and grade 3 tumors (p = 0.04). The patients with dominant-negative mutation had significantly shorter survival than patients with no mutation (p < 0.0001) and those with a recessive mutation (p = 0.01) in the p53 gene. No difference in survival was found between the patients with tumors harboring a recessive p53 mutation and those with tumors harboring a wild-type p53. Multivariate analysis revealed that dominant-negative p53 mutation (p = 0.019), FIGO stage (p = 0.0037) and histologic subtype (p = 0.014) were independently related to patient survival. Dominant-negative p53 mutation was the most important prognostic factor for stage III/IV endometrial cancer (p = 0.0023). In conclusion, dominant-negative p53 mutation is often found in advanced stages and aggressive histologic subtypes of endometrial cancer and it is a strong predictor of survival of patients with advanced endometrial cancer. To elucidate further the role of p53 mutation in endometrial cancer, it is necessary to investigate gain-of-function activity involving dominant-negative p53 mutant proteins.
