  • Article: Transcript Expression in Endometrial Cancers from Black and White Patients.
    [show abstract] [hide abstract]
    ABSTRACT: OBJECTIVE: Previous studies suggest that differences in molecular features of endometrial cancers between racial groups may contribute to the poorer survival in Blacks. The objective of this investigation was to determine whether gene expression among endometrial cancers is different between Blacks and Whites. METHODS: Fresh frozen tumors from 25 Black patients were matched by stage, grade, and histology to endometrial cancer specimens from 25 White patients. Each case was macrodissected to produce specimens possessing a minimum of 75% cancer cellularity. A subset of 10 matched pairs was also prepared using laser microdissection (LMD) to produce specimens possessing a minimum of 95% cancer cells. Total RNA isolated from each sample was analyzed using the Affymetrix Human Genome U133 Plus 2.0 arrays. Data were analyzed using principal component analysis and binary class comparison analyses. RESULTS: Unsupervised analysis of the 50 endometrial cancers failed to identify global gene expression profiles unique to Black or White patients. In a subset analysis of 10 matched pairs from Blacks and Whites prepared using LMD and macrodissection, unsupervised analysis did not reveal a unique gene expression profile associated with race in either set, but associations were identified that relate to sample preparation technique, histology and stage. CONCLUSIONS: Our microarray data revealed no global gene expression differences and identified few individual gene differences between endometrial cancers from Blacks and Whites. More comprehensive methods of transcriptome analysis could uncover RNAs that may underpin the disparity of outcome or prevalence of endometrial cancers in Blacks and Whites.

  • Article: Mitochondrial proteomic analysis of Cisplatin resistance in ovarian cancer.
    [show abstract] [hide abstract]
    ABSTRACT: Epithelial ovarian cancer (EOC) is the leading cause of death among women with gynecologic malignancies and accounts for approximately 6% of cancer deaths among women. Cisplatin and its analogues form the backbone of the most active chemotherapy regimens in advanced EOC; however, development of platinum resistance is common and typically marks a transition in which curing the patient is no longer possible. An emerging theme in many cancers is that mitochondrial dysfunction contributes to an aggressive carcinogenic phenotype. We hypothesized that changes in the mitochondrial proteome are required to support development of cisplatin resistance in human EOC. To investigate this hypothesis, an organellar proteomics approach was utilized to quantify alterations in protein abundance in mitochondria enriched from isogenic cisplatin-sensitive (A2780) and -resistant (A2780-CP20) human EOC cells. Protein isolates from mitochondria-enriched fractions were analyzed by high resolution liquid chromatography-tandem mass spectrometry (LC-MS/MS), and relative abundance of identified proteins was quantified by spectral counting. Pathway analyses revealed significant increases in notch signaling pathways, cell survival, and alternate apoptotic pathways in the A2780-CP20 subtype. Among the alterations identified in the mitochondrial proteomic composition in cisplatin-resistant EOC cells, activated leukocyte cell adhesion molecule (AKAP12) and A kinase anchoring protein 12 (AKAP12) were elevated, while nestin was diminished in the mitochondrial fraction of A2780-CP20 relative to A2780. This was verified by immunoblot analysis. These results confirm that important changes in the mitochondrial proteome, many of which promote evasion of apoptosis and tumor invasiveness and metastasis, are present in cisplatin-resistant EOC.

  • Article: Sexual Self Schema as a Moderator of Sexual and Psychological Outcomes for Gynecologic Cancer Survivors
    [show abstract] [hide abstract]
    ABSTRACT: Gynecologic cancer patients are at high risk for emotional distress and sexual dysfunction. The present study tested sexual self schema as an individual difference variable that might be useful in identifying those at risk for unfavorable outcomes. First, we tested schema as a predictor of sexual outcomes, including body change stress. Second, we examined schema as a contributor to broader quality of life outcomes, specifically as a moderator of the relationship between sexual satisfaction and psychological statue (depressive symptoms and quality of life). A cross-sectional design was used. Gynecologic cancer survivors (N=175) 2–10years post treatment were assessed during routine follow up. In regression analyses controlling for sociodemographic variables, patients’ physical symptoms/signs as evaluated by nurses, health status, and extent of partner sexual difficulties, sexual self schema accounted for significant variance in the prediction of current sexual behavior, responsiveness, and satisfaction. Moreover, schema moderated the relationship between sexual satisfaction and psychological outcomes, suggesting that a positive sexual self schema might “buffer” patients from depressive symptoms when their sexual satisfaction is low. Furthermore, the combination of a negative sexual self schema and low sexual satisfaction might heighten survivors’ risk for psychological distress, including depressive symptomatology. These data support the consideration of sexual self schema as a predictor of sexual morbidity among gynecologic cancer survivors.

  • Article: Physical Sequelae and Depressive Symptoms in Gynecologic Cancer Survivors: Meaning in Life as a Mediator
    [show abstract] [hide abstract]
    ABSTRACT: BackgroundContinuing symptoms and poor health following cancer treatments may alter meaning in life for cancer survivors. Gynecologic cancer survivors are particularly troubled with physical sequelae. In addition, for the most common sites of disease, such as breast and gynecologic cancers, the prevalence of depression is also high. PurposeThis study tests meaning in life as a mechanism for the relationship between physical symptoms and depressive symptoms. MethodsGynecologic cancer survivors (N = 260) participated. Measures of physical sequelae (nurse rated symptoms/signs, patient-reported gynecologic symptoms), meaning in life (harmony, life purpose, spirituality, and conversely, confusion and loss), and depressive symptoms were obtained at the time of a routine clinical follow-up visit 2–10years following the completion of treatment. Latent variables were defined, and structural equation modeling tested a mediator model. ResultsAnalyses support partial mediation. That is, survivors with more physical sequelae also reported lower levels of meaning in life, which was associated with higher levels of depressive symptoms. ConclusionsGynecologic cancer patients have been neglected in psychosocial research, and findings highlight the importance of existential issues in their lives. While many adjust well, those with persistent physical functioning deficits may experience depressive symptoms. By appreciating the role of meaning in their experience, we may help survivors foster their own growth and perspectives important for their future.

  • Article: Should stage IIIC ovarian cancer be further stratified by intraperitoneal vs. retroperitoneal only disease?: a Gynecologic Oncology Group study.
    [show abstract] [hide abstract]
    ABSTRACT: To examine whether clinical outcomes varied with intraperitoneal (IP) and/or retroperitoneal (RP) involvement in stage IIIC epithelial ovarian cancer (EOC) patients with microscopic residual disease after cytoreduction. Retrospective review was performed for EOC patients enrolled in Gynecologic Oncology Group (GOG)-182 who underwent primary cytoreduction to microscopic residual disease. Patients were divided into 3 groups: stage IIIC by lymphadenopathy with <2 cm IP spread (RP); >2 cm IP spread and negative nodes (IP/RP-); and >2 cm IP dissemination and positive lymphadenopathy (IP/RP+). Product-limit and multivariate proportional hazards modeling were used. Analyses included 417 stage IIIC women who underwent primary cytoreduction with lymphadenectomy to microscopic residual. There were 203, 123, and 91 in the RP, IP/RP-, and IP/RP+ groups, respectively. IP/RP+ and IP/RP- were associated with worse progression-free survival (PFS) (Hazard Ratio (HR) 1.68, 95% confidence interval (CI) 1.23-2.30; HR 1.38, 95% CI 1.04-1.84) vs. RP only. IP/RP+ was associated with worse overall survival (OS) (HR 1.79, 95% CI 1.24-2.57) while IP/RP- trended towards worse OS (HR 1.21, 95% CI 0.85-1.73) vs. RP only. Median PFS for IP/RP+ and IP/RP- groups was 21 and 29 months, respectively, vs. 48 months in the RP group (p=0.0007) and median OS of 63 and 79 months vs. "not reached," respectively (p=0.0038). Among EOC patients surgically cytoreduced to microscopic residual disease, those upstaged to IIIC by retroperitoneal involvement demonstrated significant improvement in PFS and OS compared to patients with intraperitoneal tumor, suggesting that these women may represent a unique subset of FIGO stage IIIC patients.

    Article: Analysis of PSPHL as a Candidate Gene Influencing the Racial Disparity in Endometrial Cancer.
    [show abstract] [hide abstract]
    ABSTRACT: Endometrial cancer is the most commonly diagnosed gynecologic malignancy in the United States. A well recognized disparity by race in both incidence and survival outcome exists for this cancer. Specifically Caucasians are about two times more likely to develop endometrial cancer than are African-Americans. However, African-American women are more likely to die from this disease than are Caucasians. The basis for this disparity remains unknown. Previous studies have identified differences in the types and frequencies of gene mutations among endometrial cancers from Caucasians and African-Americans suggesting that the tumors from these two groups might have differing underlying genetic defects. We performed a gene expression microarray study in an effort to identify differentially expressed transcripts between African-American and Caucasian women's endometrial cancers. Our gene expression screen identified a list of potential biomarkers that are differentially expressed between these two groups of cancers. Of these we identified a poorly characterized transcript with a region of homology to phospho serine phosphatase (PSPH) and designated phospho serine phosphatase like (PSPHL) as the most differentially over-expressed gene in cancers from African-Americans. We further clarified the nature of expressed transcripts. Northern blot analysis confirmed the message was limited to a transcript of under 1 kB. Sequence analysis of transcripts confirmed two alternate open reading frame (ORF) isoforms due to alternative splicing events. Splice specific primer sets confirmed both isoforms were differentially expressed in tissues from Caucasians and African-Americans. We further examined the expression in other tissues from women to include normal endometrium, normal and malignant ovary. In all cases PSPHL expression was more often present in tissues from African-Americans than Caucasians. Our data confirm the African-American based expression of the PSPHL transcript in endometrial cancer and also identify its expression in other tissues from African-Americans including ovary and ovarian cancer. PSPHL represents a candidate gene that might influence the observed racial disparity in endometrial and other cancers.

  • Article: Further validation of the uterine fibroid symptom and quality-of-life questionnaire.
    [show abstract] [hide abstract]
    ABSTRACT: To further examine the reliability, validity and responsiveness of the uterine fibroid symptom and quality-of-life (UFS-QOL) questionnaire among women with and without uterine fibroids. A multicenter, non-randomized, prospective study was conducted with women undergoing treatment for uterine fibroids (fibroid treatment group [FTG]) and normal controls (normal control group [NCG]). Women in the FTG were recruited when they were scheduled for treatment; women in the NCG were recruited during their annual exam. Participants completed the UFS-QOL and a short form 36 health survey (SF-36) at enrollment and at 6 and 12 months. Descriptive statistics, Cronbach's alpha, Spearman's correlations, t tests, and general linear models were used to analyze the internal consistency and test-retest reliability, concurrent and discriminant validity, and responsiveness of the UFS-QOL. There were 89 NCG and 234 FTG women who completed the study. Mean age was 43.1 years for FTG and 40.8 for NCG (P < 0.001). The FTG reported significantly greater symptom severity and worse health-related quality of life (HRQL) than the NCG (all UFS-QOL subscales P < 0.001). The UFS-QOL subscales were significantly correlated in the expected direction and magnitude with each SF-36 subscale in the FTG, indicating acceptable concurrent validity. Cronbach's alphas were 0.73 to 0.97, reflecting adequate internal consistency. Each UFS-QOL subscale was responsive to changes after treatment in the FTG with effect sizes ranging between 1.1 and -2.35. The UFS-QOL remained stable in the NCG during the 1 year follow-up. The UFS-QOL is a valid and reliable measure to assess symptoms and HRQL in women with uterine fibroids and is highly responsive to treatment-related changes.

  • Article: Longitudinal evaluation of cancer-associated biomarkers before and after weight loss in RENEW study participants: implications for cancer risk reduction.
    [show abstract] [hide abstract]
    ABSTRACT: Obesity is a major risk factor for the development of endometrial cancer (EC). An improved understanding of biologic mechanisms associated with weight loss, including alteration in inflammation, hormonal balance, and cancer antigens expression may lead to the development of effective cancer prevention strategies. The goal of this study was to explore longitudinal biomarker changes in obese women who underwent weight loss intervention, testing the hypothesis biomarker levels can be altered through intentional weight loss. Serum samples from 89 participants with Class II and Class III obesity and 43 non morbidly obese comparisons were obtained in Re-Energize with Nutrition, Exercise and Weight Loss (RENEW) study as previously reported. Twenty-one bead-based xMAP immunoassays were utilized, including cancer-associated antigens, cytokines, chemokines, and hormones. One-way repeated measures ANOVA was used to examine the association between changes in biomarker expression levels over time (baseline, 6 months and 12 months). Linear mixed effects models were used to examine longitudinal relationships between biomarker expression levels. Mean levels of VEGF, soluble E-selectin, GH, adiponectin, IL-6, IL-7, CA-125, and IGFBP-1 significantly differed between time periods. In adjusted mixed linear models, decreasing BMI was significantly associated with lower levels of soluble E-selectin and IL-6 and increases in GH, adiponectin, and IGFBP-1. This is one of the first efforts to explore changes in cancer-associated biomarkers in a cohort of weight loss research participants at high risk for EC development. Our findings demonstrate that changes in the expression of markers can be achieved with weight loss intervention.

  • Article: PPP2R1A mutations are common in the serous type of endometrial cancer.
    [show abstract] [hide abstract]
    ABSTRACT: Recently unbiased sequencing efforts identified PPP2R1A mutations in clear cell ovarian cancers (OCC). Similar mutations were also noted with high frequency in uterine serous carcinoma. Because the endometrium develops from the same developmental precursors we further examined the hypothesis that PPP2R1A mutations might also occur in diverse histologic subtypes of uterine cancer. We sequenced the PPP2R1A in 22 cell line models of uterine cancer and 10 primary cancers. We found no mutations in the cell lines originally derived from endometrioid (n = 13), undifferentiated (n = 3), clear cell (n = 1), and carcinosarcoma (n = 3) cancers. However, we found a CCC (Pro) to CGC (Arg) codon 179 mutation in the ACI-158 serous carcinoma cell line, a CCC (Pro) to CTC (Leu) in a primary serous carcinoma as well as a CGC (Arg) to CAC (His) codon 258 mutation in a poorly differentiated endometrioid cancer. We sequenced a large panel of endometrial malignancies (n = 181) and found 12 mutants. Importantly, we confirmed a high frequency of mutation in 8 of 25 (32%) serous carcinomas a subtype with well-recognized poor prognosis. Mutations were infrequent in endometrioid cancer and absent in clear cell and carcinosarcoma subtypes. The PPP2R1A mutation regions are conserved among species and known to interact with the regulatory subunits of the PP2A enzyme. PPP2R1A mutant endometrial cancers may represent good candidates for personalized drug therapies particularly for women with the lethal serous histologic variant of uterine cancer. © 2011 Wiley Periodicals, Inc.

    Article: Racial disparities in histopathologic characteristics of uterine cancer are present in older, not younger blacks in an equal-access environment.
    [show abstract] [hide abstract]
    ABSTRACT: We sought to determine whether racial disparities in tumor characteristics among uterine cancer patients persisted, and varied by age, in an equal-access healthcare population. The distributions of tumor histology, stage and grade by race were compared for uterine cancers diagnosed from 1990 to 2003 using data from the U.S. Department of Defense's Automated Central Tumor Registry. Comparisons were conducted overall and stratified by age (<50, ≥50) using the Chi-square test. Of 2582 uterine tumors identified, 2057 (79.7%) were diagnosed among White women and 183 (7.1%) among Black women. Among all women analyzed, Blacks were more likely than Whites to present with non-endometrioid tumors (47.7% vs 23.5%, p<0.01), non-localized tumors (31.8% vs 24.5%, p=0.02), and poorly differentiated tumors (20.5% vs 15.0%, p<0.01). Among women 50 years and older, similar significant racial disparities were observed. However, no significant racial differences were observed among young patients. When comparisons were restricted to endometrioid histology adenocarcinomas, trends in age-specific disparities for older women were observed. Our study suggests that racial disparities in uterine cancers persist between Blacks and Whites in an equal-access population. Blacks endure higher stage and grade tumors, and more aggressive histologies. This disparity in clinicopathologic factors is confined to women older than 50 years. Multiple factors such as racial variation in age-related health knowledge/behavior and estrogen metabolism may be related to the racial disparity.

  • Article: The impact of disease distribution on survival in patients with stage III epithelial ovarian cancer cytoreduced to microscopic residual: a Gynecologic Oncology Group study.
    [show abstract] [hide abstract]
    ABSTRACT: To assess the survival impact of initial disease distribution on patients with stage III epithelial ovarian cancer (EOC) cytoreduced to microscopic residual. We reviewed data from 417 stage III EOC patients cytoreduced to microscopic disease and given adjuvant intravenous platinum/paclitaxel on one of three randomized Gynecologic Oncology Group (GOG) trials. We subdivided patients into three groups based on preoperative disease burden: (1) minimal disease (MD) defined by pelvic tumor and retroperitoneal metastasis (2) abdominal peritoneal disease (APD) with disease limited to the pelvis, retroperitoneum, lower abdomen and omentum; and (3) upper abdominal disease (UAD) with disease affecting the diaphragm, spleen, liver or pancreas. We assessed the survival impact of potential prognostic factors, focusing on initial disease distribution using a proportional hazards model and estimated Kaplan-Meier survival curves. The study groups had similar clinicopathologic characteristics. Median overall survival (OS) was not reached in MD patients compared to 80 and 56 months in the APD and UAD groups (P<0.05). The five-year survival percentages for MD, APD, and UAD were 67%, 63%, and 45%. In multivariate analysis, the UAD group had a significantly worse prognosis than MD and APD both individually and combined (Progression Free Survival (PFS) Hazards Ratio (HR) 1.44; P=0.008 and OS HR 1.77; P=0.0004 compared to MD+APD). Stage III EOC patients with initial disease in the upper abdomen have a worse prognosis despite cytoreductive surgery to microscopic residual implying that factors beyond cytoreductive effort are important in predicting survival.

    Article: Identifier mapping performance for integrating transcriptomics and proteomics experimental results.
    [show abstract] [hide abstract]
    ABSTRACT: Studies integrating transcriptomic data with proteomic data can illuminate the proteome more clearly than either separately. Integromic studies can deepen understanding of the dynamic complex regulatory relationship between the transcriptome and the proteome. Integrating these data dictates a reliable mapping between the identifier nomenclature resultant from the two high-throughput platforms. However, this kind of analysis is well known to be hampered by lack of standardization of identifier nomenclature among proteins, genes, and microarray probe sets. Therefore data integration may also play a role in critiquing the fallible gene identifications that both platforms emit. We compared three freely available internet-based identifier mapping resources for mapping UniProt accessions (ACCs) to Affymetrix probesets identifications (IDs): DAVID, EnVision, and NetAffx. Liquid chromatography-tandem mass spectrometry analyses of 91 endometrial cancer and 7 noncancer samples generated 11,879 distinct ACCs. For each ACC, we compared the retrieval sets of probeset IDs from each mapping resource. We confirmed a high level of discrepancy among the mapping resources. On the same samples, mRNA expression was available. Therefore, to evaluate the quality of each ACC-to-probeset match, we calculated proteome-transcriptome correlations, and compared the resources presuming that better mapping of identifiers should generate a higher proportion of mapped pairs with strong inter-platform correlations. A mixture model for the correlations fitted well and supported regression analysis, providing a window into the performance of the mapping resources. The resources have added and dropped matches over two years, but their overall performance has not changed. The methods presented here serve to achieve concrete context-specific insight, to support well-informed decisions in choosing an ID mapping strategy for "omic" data merging.

  • Article: Proteomic analysis of stage I endometrial cancer tissue: identification of proteins associated with oxidative processes and inflammation.
    [show abstract] [hide abstract]
    ABSTRACT: The present study aimed to identify differentially expressed proteins employing a high resolution mass spectrometry (MS)-based proteomic analysis of endometrial cancer cells harvested using laser microdissection. A differential MS-based proteomic analysis was conducted from discrete epithelial cell populations gathered by laser microdissection from 91 pathologically reviewed stage I endometrial cancer tissue samples (79 endometrioid and 12 serous) and 10 samples of normal endometrium from postmenopausal women. Hierarchical cluster analysis of protein abundance levels derived from a spectral count analysis revealed a number of proteins whose expression levels were common as well as unique to both histologic types. An independent set of endometrial cancer specimens from 394 patients were used to externally validate the differential expression of select proteins. 209 differentially expressed proteins were identified in a comparison of stage I endometrial cancers and normal post-menopausal endometrium controls (Q<0.005). A number of differentially abundant proteins in stage I endometrial cancer were identified and independently validated by western blot and tissue microarray analyses. Multiple proteins identified with elevated abundance in stage I endometrial cancer are functionally associated with inflammation (annexins) and oxidative processes (peroxiredoxins). PRDX1 and ANXA2 were both confirmed as being overexpressed in stage I cancer compared to normal endometrium by independent TMA (Q=0.008 and Q=0.00002 respectively). These data provide the basis for further investigation of previously unrecognized novel pathways involved in early stage endometrial carcinogenesis and provide possible targets for prevention strategies that are inclusive of both endometrioid and serous histologic subtypes.

  • Article: Racial disparities in risk of second primary cancers in endometrial cancer patients: Analysis of SEER Data.
    [show abstract] [hide abstract]
    ABSTRACT: INTRODUCTION: Endometrial cancer (EC) is the most common gynecologic cancer in the United States. Racial disparities in the incidence and mortality of this cancer are apparent; black women are less likely to develop this malignancy, and yet are more likely to die when diagnosed. Racial differences of second primary cancer (SPC) have not been examined and are the goal of this study. METHODS: Using the National Cancer Institute's Surveillance, Epidemiology, and End Results database, SPC risk in white and black EC cases was compared to the general population and to women with other primary cancers. Standardized incidence ratios (SIRs) of SPC (overall and by tumor site) with 95% confidence intervals were calculated. Poisson regression was used to estimate the race-specific risk of SPC in EC cases treated with radiotherapy vs. non-irradiated cases. RESULTS: The analysis included 11,047 EC cases diagnosed between 1973 and 2007 that developed a SPC. Overall risk of SPC in white EC cases was significantly lower than the general population (SIR=0.85, 95% CI: 0.84, 0.87), but significantly higher in black EC cases (SIR=1.19, 95% CI: 1.08, 1.31). White EC cases treated with radiotherapy were more likely to develop SPC compared to non-irradiated cases (IRR=1.18, 95% CI: 1.14, 1.23). CONCLUSIONS: This is the first analysis of race-specific SPC risk in EC cases and it suggests differences between white and black cases. Although exploratory, these data provide important clues about the etiology of SPC in patients with EC. This analysis also highlights the need for careful monitoring following diagnosis and treatment of EC.

    Article: Sexual morbidity associated with poorer psychological adjustment among gynecological cancer survivors.
    [show abstract] [hide abstract]
    ABSTRACT: Sexual morbidity is a distressing and undertreated problem in gynecological cancer survivorship known to occur early and persist well beyond the period of physical recovery. Although often studied as a separate domain, sexuality represents an integral component of psychological adjustment and quality of life (QoL) that is adversely affected by cancer treatments. The present study tests the association between sexual morbidity, and adverse psychological adjustment and QoL outcomes. A cross-sectional design was used. The participants were gynecological (cervical, endometrial, ovarian, and vulvar) cancer survivors who were partnered (N = 186), whose cancer was diagnosed 2 to 10 years previously, and who were at least 6 months post any cancer therapy. Most had been found to have early-stage disease (70%) and were treated with hysterectomy (77%), chemotherapy (43%), and/or radiotherapy (23%). Sexual morbidity was operationalized as a multidimensional construct including sexual behavior, sexual functioning, and subjective sexual satisfaction, assessed by patient self-report. Outcomes included self-reported depressive symptoms, traumatic stress symptoms, cancer-specific stress, stress about body changes, and QoL. Nurse-rated of performance status and disruptive signs/symptoms of treatment toxicity, as well as relevant sociodemographic and disease variables were collected as potential controls. Hierarchical multiple regression analyses tested sexual morbidity as a predictor of poor outcomes. All statistical models were significant, accounting for 12% to 53% of the variance in psychological adjustment/QoL. Sexual morbidity covaried with worsened depressive symptoms, body change stress, and psychological QoL beyond the negative contributions of (older) age, (poorer) performance status, and (greater) fatigue. Notably, disease and treatment variables were not statistically significant correlates of psychological adjustment or QoL. These findings suggest that prevention or treatment of sexual morbidity might foster improved psychological adjustment/QoL. Given the high rates of sexual morbidity in this population and the connection between sexuality and broader psychological adjustment/QoL, there is a clear need for better integration of sexuality rehabilitation into routine clinical care.

  • Article: Direct and buffering effects of social support among gynecologic cancer survivors.
    [show abstract] [hide abstract]
    ABSTRACT: There are few studies of QoL among long-term gynecologic cancer survivors; available data suggest significant sequelae of disease and treatment. Research clarifying circumstances that improve difficult survivorship trajectories is lacking. The present study examines whether social support moderates the relationship between physical functioning and psychological outcomes by testing the stress-buffering hypothesis. Participants (N = 260) were gynecologic cancer survivors (cervical, n = 47; endometrial, n = 133; ovarian, n = 69; vulvar, n = 11). Compromised physical health was conceptualized as multidimensional. Social support (SNI, PSS-Fa, PSS-Fr, ISEL) was tested as a buffer of adverse psychological outcomes (IES-R, CES-D). Results for traumatic stress provided evidence for buffering; whereas social support was of general benefit for depressive symptoms. Effects varied by source and type of support. These results suggest that circumstances for gynecologic cancer survivors burdened with physical symptoms may be worse for those with fewer support resources, providing needed insight into a common target of psychosocial interventions for cancer survivors.

  • Article: Clinical decision making using ovarian cancer risk assessment.
    Michael P Stany, G Larry Maxwell, G Scott Rose
    [show abstract] [hide abstract]
    ABSTRACT: OBJECTIVE: Although any adnexal abnormality found at imaging can be concerning for an ovarian malignancy, the clinician must perform an evaluation to decide if the actual likelihood of malignancy justifies the risk of surgery. When determining the likelihood of an asymptomatic, incidental adnexal mass being malignant, the provider must answer one important question: Do the clinical findings warrant the potential morbidity of surgery? This article will focus on the decision making that goes into such an evaluation. CONCLUSION: A patient's medical history, physical examination, CA-125 level, and imaging characteristics are all factors that impact the ultimate decision of whether a patient can be observed with repeat imaging or should proceed to surgical evaluation.

  • Article: Chemotherapy intensity and toxicity among black and white women with advanced and recurrent endometrial cancer: a Gynecologic Oncology Group Study.
    [show abstract] [hide abstract]
    ABSTRACT: The purpose of this study was to confirm whether black and white women with endometrial cancer are equally tolerant of chemotherapy and identify factors that impact survival. A retrospective review of 169 black women and 982 white women with the International Federation of Gynecologists and Obstetricians stage III, stage IV, or recurrent endometrial carcinoma was performed. All patients received doxorubicin combined with cisplatin. Chemotherapy parameters that were reviewed included relative dose, relative time, and relative dose intensity. Treatment cycles > or =7 were defined as treatment completion. Although black patients were more likely to experience grades 3-4 anemia (20% vs 14%) and genitourinary (5% vs 1%) toxicity, and less likely to experience severe gastrointestinal toxicity (10% vs 17%), the overall incidence of grades 3-4 treatment-related chemotoxicity was the same between the 2 groups (82% vs 82%). There were no differences in the number of cycles received, relative dose (0.57 vs 0.58), relative time (0.77 vs 0.78), or relative dose intensity (0.76 vs 0.76) for black and white patients. Black patients with advanced stage or recurrent endometrial cancer, treated on 4 Gynecologic Oncology Group (GOG) protocols, had similar dose intensity and severe chemotherapy-related toxicity compared with white patients, suggesting that previously described racial disparities in survival among patients in GOG trials may have an novel etiology.

    [show abstract] [hide abstract]
    ABSTRACT: Diffuse laminar endocervical glandular hyperplasia is extremely rare with only 14 cases reported in the literature. Diffuse laminar endocervical glandular hyperplasia is a benign lesion that is easily confused with malignancy. We present a 22-year-old woman referred to our gynecologic oncology service with a 2.0 x 4.0-cm exophytic cervical mass. Colposcopic-directed cervical biopsies were diagnosed as adenocarcinoma, suggestive of minimal deviation adenocarcinoma. Computed tomographic scans of the abdomen and the pelvis failed to reveal any metastatic foci. A radical abdominal hysterectomy with pelvic and para-aortic lymph node sampling was performed without complications. Final pathology revealed diffuse laminar endocervical glandular hyperplasia. Diffuse laminar endocervical glandular hyperplasia is an uncommon histological type of pseudoneoplastic glandular lesions that may be found in the cervix, and this entity should be considered in the differential diagnosis of a potentially malignant endocervical glandular lesion.
