Depression and anxiety in women with malignant ovarian germ cell (MOGCT) and sex cord stromal tumors (SCST): an analysis of the AGO-CORSETT database.

INTRODUCTION: The intention of this study was to evaluate the level of anxiety and depression of malignant ovarian germ cell (MOGCT) and sex cord stromal tumors (SCST) survivors and to identify possible alterable cofactors. METHODS: CORSETT was an observational, multicenter, mixed retrospective/prospective cohort study of the AGO Studygroup. Women who had been diagnosed with MOGCTs and SCSTs between 2001 and 2011 were asked to complete the Hospital Anxiety and Depression Scale (HADS) to evaluate distress. Predictors of distress (type of surgery, chemotherapy, time since diagnosis, recurrence, second tumor, pain) were investigated using multivariate linear regression analysis. RESULTS: 150 MOGCT and SCST patients with confirmed histological diagnosis completed the questionnaire median seven years after diagnosis. They had a HADS total score ≥ 13 indicating severe mental distress in 34% of cases. Patients after fertility-conserving surgery had lower probability of severe mental distress than those without fertility-conserving treatment (ß = - 3.1, p = 0.04). Pain was associated with the level of distress in uni- and multivariate analysis (coef 0.1, p < 0.01, coef. Beta 0.5). DISCUSSION: Severe mental distress was frequent in patients with MOGCT and SCST and the level of pain was associated with the level of distress. Fertility conserving therapy, however, was associated with less mental distress. Screening and treatment of pain and depression is required to improve mental well-being in survivors of MOGCT and SCST.

Outcome of breast cancer patients with low hormone receptor positivity: analysis of a 15-year population-based cohort.

BACKGROUND: Guideline recommendations for the treatment of breast cancer with low hormone receptor (HR) expression (1%-9%) are ambiguous and several studies showed more similarities with HR-negative tumors than with HR strongly positive tumors (≥10%). We used a population-based 15-year cohort to compare patient characteristics and outcome of HR low positive tumors with HR-negative and HR strongly positive tumors, respectively. PATIENTS AND METHODS: A total of 38  560 women diagnosed with early invasive breast cancer between 2004 and 2018 within the scope of the Munich Cancer Registry with 4.9 million inhabitants were included. Descriptive analyses of prognostic factors, treatment, and outcome analyses using the Kaplan-Meier method; cumulative incidence in consideration of competing risks; and multivariate analyses (Cox regression and Fine-Gray model) were conducted. Endpoints were time to local recurrence (TTLR), time to lymph node recurrence (TTLNR), time to metastasis (TTM), overall survival (OS), and relative survival (RS). RESULTS: A total of 861 patients (2%) had HR low positive, 4862 (13%) HR-negative, and 32  837 (85%) HR strongly positive tumors. Within the HER2-negative cohort (n = 33  366), survival of HR low positive tumors was significantly worse than that of HR strongly positive tumors [OS hazard ratio 0.66 (95% confidence interval 0.55-0.78)], whereas between HR low positive and HR-negative tumors no significant survival difference could be detected [OS hazard ratio 0.93 (95% confidence interval 0.78-1.11)]. TTLR, TTLNR, and TTM showed similar results. By contrast, within the HER2-positive cohort (n = 5194), no statistically significant differences between the three HR groups could be detected in multivariate analyses. CONCLUSION: Current definitions for HR positivity and its clinical relevance should be reconsidered. Patients with HR low positive/HER2-negative tumors could be regarded and treated similar to patients with triple-negative tumors.

[TNM classification of gynecologic malignancies : What remains to be done beyond 2017?] / TNM-Klassifikation gynäkologischer Tumoren : Was bleibt über 2017 hinaus zu tun?

For some gynecologic malignancies, there are disagreements between the most recent WHO and TNM classifications and the recommendations of the International Collaboration of Cancer Reporting. These discrepancies are addressed and discussed in this paper. The WHO definition for primary vaginal cancer does not match the TNM definition. The paper also discusses and provides TNM classifications for rare gynecologic tumors like primary malignant vulvar melanomas, sarcomas of the vulva, perivascular epithelioid cell tumor (PECom) of the uterus, undifferentiated uterine sarcomas, and extra-intestinal gastrointestinal stromal tumors (GIST), and provides some recommendations for the reporting and categorization of regional lymph nodes in nonuterine serous pelvic cancer.

[S3 guidelines on the diagnosis and treatment of carcinoma of the endometrium : Requirements for pathology]. / S3-Leitlinie Diagnostik und Therapie des Endometriumkarzinoms : Anforderungen an die Pathologie.

The present article summarises the relevant aspects of the S3 guidelines on endometrioid carcinomas. The recommendations include the processing rules of fractional currettings as well as for hysterectomy specimens and lymph node resections (including sentinel lymph nodes). Besides practical aspects, the guidelines consider the needs of the clinicians for appropriate surgical and radiotherapeutic treatment of the patients. Carcinosarcomas are assigned to the endometrial carcinoma as a special variant. For the first time, an algorithmic approach for evaluation of the tumour tissue for Lynch syndrome is given. Prognostic factors based on morphologic findings are summarised.

[The 2016 update of the S3 guideline for malignant tumours of the ovary : Role of pathology in diagnosis, therapy and clinical management of epithelial tumours]. / Update der S3-Leitlinie für maligne Ovarialtumoren 2016 : Rolle der Pathologie in Diagnostik, Therapie und Nachsorge epithelialer Tumoren.

Tumor stage, residual postoperative tumor, histological type and grading are considered among the main prognostic parameters in the consensus-based recommendations in the new S3 guidelines for diagnosis, treatment and clinical follow-up of malignant tumours of the ovary. Based on the 2014 update of the WHO Classification of Tumours of the Female Reproductive Organs this article summarizes the most significant changes. For example now the same TNM and FIGO classification applies for tumours of the ovary, peritoneum or fallopian tube. Noninvasive implants of serous borderline tumours are now named implants. In contrast, invasive implants are regarded as low-grade serous carcinoma. By presenting the current background information, we want to provide a basis for discussion, regarding more detailed consensus recommendations for pathologists and clinicians in the future.

[Grading of gynecological tumors : Current aspects]. / Grading gynäkologischer Tumoren : Aktuelle Aspekte.

Histopathological assessment of the tumor grade and cell type is central to the management and prognosis of various gynecological malignancies. Conventional grading systems for squamous carcinomas and adenocarcinomas of the vulva, vagina and cervix are poorly defined. For endometrioid tumors of the female genital tract as well as for mucinous endometrial, ovarian and seromucinous ovarian carcinomas, the 3­tiered FIGO grading system is recommended. For uterine neuroendocrine tumors the grading system of the gastrointestinal counterparts has been adopted. Uterine leiomyosarcomas are not graded. Endometrial stromal sarcomas are divided into low and high grades, based on cellular morphology, immunohistochemical and molecular findings. A chemotherapy response score was established for chemotherapeutically treated high-grade serous pelvic cancer. For non-epithelial ovarian malignancies, only Sertoli-Leydig cell tumors and immature teratomas are graded. At this time molecular profiling has no impact on the grading of tumors of the female genital tract.

The EndoPredict score provides prognostic information on late distant metastases in ER+/HER2- breast cancer patients.

BACKGROUND: ER+/HER2- breast cancers have a proclivity for late recurrence. A personalised estimate of relapse risk after 5 years of endocrine treatment can improve patient selection for extended hormonal therapy. METHODS: A total of 1702 postmenopausal ER+/HER2- breast cancer patients from two adjuvant phase III trials (ABCSG6, ABCSG8) treated with 5 years of endocrine therapy participated in this study. The multigene test EndoPredict (EP) and the EPclin score (which combines EP with tumour size and nodal status) were predefined in independent training cohorts. All patients were retrospectively assigned to risk categories based on gene expression and on clinical parameters. The primary end point was distant metastasis (DM). Kaplan-Meier method and Cox regression analysis were used in an early (0-5 years) and late time interval (>5 years post diagnosis). RESULTS: EP is a significant, independent, prognostic parameter in the early and late time interval. The expression levels of proliferative and ER signalling genes contribute differentially to the underlying biology of early and late DM. The EPclin stratified 64% of patients at risk after 5 years into a low-risk subgroup with an absolute 1.8% of late DM at 10 years of follow-up. CONCLUSION: The EP test provides additional prognostic information for the identification of early and late DM beyond what can be achieved by combining the commonly used clinical parameters. The EPclin reliably identified a subgroup of patients who have an excellent long-term prognosis after 5 years of endocrine therapy. The side effects of extended therapy should be weighed against this projected outcome.

EndoPredict improves the prognostic classification derived from common clinical guidelines in ER-positive, HER2-negative early breast cancer.

BACKGROUND: In early estrogen receptor (ER)-positive/HER2-negative breast cancer, the decision to administer chemotherapy is largely based on prognostic criteria. The combined molecular/clinical EndoPredict test (EPclin) has been validated to accurately assess prognosis in this population. In this study, the clinical relevance of EPclin in relation to well-established clinical guidelines is assessed. PATIENTS AND METHODS: We assigned risk groups to 1702 ER-positive/HER2-negative postmenopausal women from two large phase III trials treated only with endocrine therapy. Prognosis was assigned according to National Comprehensive Cancer Center Network-, German S3-, St Gallen guidelines and the EPclin. Prognostic groups were compared using the Kaplan-Meier survival analysis. RESULTS: After 10 years, absolute risk reductions (ARR) between the high- and low-risk groups ranged from 6.9% to 11.2% if assigned according to guidelines. It was at 18.7% for EPclin. EPclin reassigned 58%-61% of women classified as high-/intermediate-risk (according to clinical guidelines) to low risk. Women reclassified to low risk showed a 5% rate of distant metastasis at 10 years. CONCLUSION: The EPclin score is able to predict favorable prognosis in a majority of patients that clinical guidelines would assign to intermediate or high risk. EPclin may reduce the indications for chemotherapy in ER-positive postmenopausal women with a limited number of clinical risk factors.

Expression pattern and prognostic potential of histamine receptors in epithelial ovarian cancer.

PURPOSE: Despite recent advances in the treatment of ovarian cancer (OC), long-term remissions remain scarce. For a targeted approach, prognostic markers are indispensable for predicting survival and treatment response. Given their association with multiple hallmarks of cancer, histamine receptors (HR) are emerging as promising candidates. Here, we investigate their expression pattern and prognostic value in OC. METHODS: Specimens of 156 epithelial OC patients were collected during cytoreductive surgery at the Department of Obstetrics and Gynecology, LMU, between 1990 and 2002 and combined in a tissue microarray. Immunohistochemical staining of the HR H1, H2, H3 and H4 was quantified by an immunoreactive score and linked with clinico-pathological data by Spearman's correlation. Via ROC curve analysis, optimal cut-off values for potential prognostic markers were defined. Overall survival (OS) was visualized in Kaplan-Maier curves and significances determined by log-rank testing. A Cox regression model was applied for multivariate analysis. RESULTS: HR H3 and H4 expression was restricted to the cytosol of OC cells, while H1 was also present in the nucleus. A significant association between HR H1, H3 and H4 expression with several clinico-pathological parameters was revealed. In addition, HR H1 and H3 expression correlated positively, HR H4 expression negatively with OS. In addition, HR H3 was identified as independent prognostic marker for OS. HR H2 expression had no prognostic value. CONCLUSIONS: HR H1, H3 and H4 could serve as potential predictors for OS of OC patients. Further research is warranted to elucidate their pathophysiologic role and their predictive and therapeutic potential in OC.

Characterization and prognostic impact of ACTBL2-positive tumor-infiltrating leukocytes in epithelial ovarian cancer.

Actin beta-like 2 (ACTBL2) was recently identified as a new mediator of migration in ovarian cancer cells. Yet, its impact on tumor-infiltrating and thus migrating leukocytes (TILs) remains to date unknown. This study characterizes the subset of ACTBL2-expressing TILs in epithelial ovarian cancer (EOC) and elucidates their prognostic influence on the overall survival of EOC patients with special regard to different histological subtypes. Comprehensive immunohistochemical analyses of Tissue-Microarrays of 156 ovarian cancer patients revealed, that a tumor infiltration by ACTBL2-positive leukocytes was significantly associated with an improved overall survival (OS) (61.2 vs. 34.4 months; p = 0.006) and was identified as an independent prognostic factor (HR = 0.556; p = 0.038). This significant survival benefit was particularly evident in patients with low-grade serous carcinoma (OS: median not reached vs. 15.6 months, p < 0.001; HR = 0.058, p = 0.018). In the present cohort, ACTBL2-positive TILs were mainly composed of CD44-positive cytotoxic T-cells (CD8+) and macrophages (CD68+), as depicted by double-immunofluorescence and various immunohistochemical serial staining. Our results provide significant evidence of the prognostic impact and cellular composition of ACTBL2-expressing TILs in EOC. Complementary studies are required to analyze the underlying molecular mechanisms of ACTBL2 as a marker for activated migrating leukocytes and to further characterize its immunological impact on ovarian carcinogenesis.

Free asymmetric dimethylarginine (ADMA) is low in children and adolescents with classical phenylketonuria (PKU).

INTRODUCTION: Free asymmetric dimethylarginine (ADMA) is a competitive inhibitor of the nitric oxide synthases (NOS). Suppression of nitric oxide (NO) synthesis increases the risk of atherosclerosis. Nevertheless, in the condition of oxidative stress, NOS blockade by ADMA may exert protective effects. Protein metabolism is altered in patients with phenylketonuria (PKU) on dietary treatment and as shown recently, oxidative stress is high in PKU. Since free ADMA concentrations are determined by both protein metabolism and oxidative stress we hypothesized, that free ADMA levels may be elevated in PKU patients. DESIGN: Sixteen patientswith PKU on dietary treatment (mean age 10.1 ± 5.2 yrs), and 91 healthy children (mean age 11.6 ± 3.7 yrs) participated in a cross sectional study. RESULTS: ADMA, total homocysteine (tHcy) and blood glucose were lower and the L-arginine/ADMA ratio was higher in PKU patients compared to controls. No significant correlation was present between phenylalanine (Phe) concentrations, protein intake, and lipid profile, history of cardiovascular disease or ADMA. DISCUSSION: In contrast to our hypothesis, ADMAwas lower and the L-arginine/ADMA ratio was higher in PKU patients. Therefore, in PKU patients, the regulating function of ADMA on NO synthesis is altered and may thus contribute to oxidative stress.

Relapse and survival in early-stage ovarian cancer.

OBJECTIVE: To analyze the prognostic influence of patient characteristics, diagnostic markers or therapeutic procedures in women diagnosed with early ovarian cancer based on relapse and survival in long term follow-up. MATERIALS AND METHODS: All women diagnosed and treated for early ovarian cancer at our institution between 1992 and 2006 were included in this retrospective study. Patient characteristics, clinical data including operative procedure, serum markers, stage and histology at first diagnosis as well as follow-up data were analyzed with regard to survival times and relapse rates. RESULTS: Altogether, 116 patients were included. Mean follow-up time was 7.0 +/- 3.3 years (range 2-14 years). Histology revealed a serous tumor in 64.7% (75/116), mucinous in 19.0% (22/116) and endometiroid tumors in 7.8% (9/116) of all cases. TNM classification was pT1a in 49.1% (57/116), pT1b in 6% (7/116), pT1c in 32.8% (38/116) and pT2a in 12.1% (14/116). Lymph node involvement (N1) was found in 3.4% of all patients. 17 deaths and 17 relapses (each 14.7%) were documented during follow-up time with a mean time to recurrence of 3.3 +/- 2.1 years (range 1-7 years). The general 1-, 2-, 5- and 10-year survival rates were 99, 95.7 and 88.9 and 81.0%, respectively. Patients with tumor stage pT1a and pT1b had a significantly better survival (P = 0.0003) and significantly lower risk of recurrence (P = 0.0138) compared to higher tumor stages. Moreover, patients who experienced recurrent disease or presented with ascites at primary diagnosis had a significantly worse overall survival (recurrence: hazard ratio 0.17, 95% confidence interval 0.0155-0.2182, P = 0.0001; ascites: HR 2.84, CI 1.1919-10.1131, P = 0.0225). The risk for recurrent disease was significantly elevated for patients with low grade (G3) tumors (P = 0.0330). Interestingly, there was neither a worse survival rate nor a higher relapse rate for patients with primary laparoscopic surgical access. CONCLUSION: Patients with early ovarian cancer stage pT1c and pT2a or low grade tumor have to be monitored closely in oncologic follow-up as they bare a significant risk for disease recurrence. Ascites at primary diagnosis, pT1c or pT2a tumor stage or recurrent disease are associated with a poor survival even in early ovarian cancer.

The presented case shows how difficult it can be to diagnose rare diseases if they present with masses in atypical locations. In an extensive further diagnostic workup other characteristic findings then point to the correct diagnosis.

[Basal and myoepithelial phenotype of metastatic mammary carcinomas. A prognostic factor in the palliative situation?]. / Basaler und myoepithelialer Phänotyp des invasiven Mammakarzinoms. Prognostischer Faktor in der palliativen Situation?

AIMS: The aim of the present study was to evaluate the prognostic impact of basal and myoepithelial phenotype in breast carcinomas (BBC and MBC) in the palliative situation. METHODS: Paraffin-embedded material from 244 primary breast carcinomas of patients with subsequent metastatic disease was stained immunohistochemically for CK 5/6, CK14, smooth-muscle actin, p63, estrogen receptor and progesterone receptor. BBC was defined as positive for CK5/6 and/or CK14 and MBC as positive for SMA and/or p63. Clinical and pathological data were available for all patients and follow-up data for 96.3% (range 5 days-151 months). RESULTS: Until the end of the follow-up period 90.2% of patients died and 6.1% are still alive. Of the tumours 28.7% could be classified as BBC and 8.2% as MBC. Kaplan Meier analysis revealed a trend for reduced survival after first diagnosis of metastasis (OASM) for BBC and MBC. Differences in survival were significant for BBC (log-rank =5.0; p=0.025), but not for MBC. CK5/6+ and CK14+ double positive tumours (n=18; 7.4%) were identified as a subgroup of BBC associated with reduced OASM (log-rank=8,6; p=0.003). This subgroup, but not BBC or MBC was an independent negative prognostic factor in a multivariate analysis including age, typing, tumour size, grading, axillary nodes, HR, Her2/neu, site of first metastasis and disease-free interval. CONCLUSION: The association of BBC and MBC with reduced OASM in metastatic breast carcinomas is not independent from established prognostic factors. CK5/6+ CK14+ double positive tumours may be a subgroup of BBC with particularly unfavourable outcome.

International practices in the dietary management of fructose 1-6 biphosphatase deficiency.

BACKGROUND: In fructose 1,6 bisphosphatase (FBPase) deficiency, management aims to prevent hypoglycaemia and lactic acidosis by avoiding prolonged fasting, particularly during febrile illness. Although the need for an emergency regimen to avoid metabolic decompensation is well established at times of illness, there is uncertainty about the need for other dietary management strategies such as sucrose or fructose restriction. We assessed international differences in the dietary management of FBPase deficiency. METHODS: A cross-sectional questionnaire (13 questions) was emailed to all members of the Society for the Study of Inborn Errors of Metabolism (SSIEM) and a wide database of inherited metabolic disorder dietitians. RESULTS: Thirty-six centres reported the dietary prescriptions of 126 patients with FBPase deficiency. Patients' age at questionnaire completion was: 1-10y, 46% (n = 58), 11-16y, 21% (n = 27), and >16y, 33% (n = 41). Diagnostic age was: <1y, 36% (n = 46); 1-10y, 59% (n = 74); 11-16y, 3% (n = 4); and >16y, 2% (n = 2). Seventy-five per cent of centres advocated dietary restrictions. This included restriction of: high sucrose foods only (n = 7 centres, 19%); fruit and sugary foods (n = 4, 11%); fruit, vegetables and sugary foods (n = 13, 36%). Twenty-five per cent of centres (n = 9), advised no dietary restrictions when patients were well. A higher percentage of patients aged >16y rather than ≤16y were prescribed dietary restrictions: patients aged 1-10y, 67% (n = 39/58), 11-16y, 63% (n = 17/27) and >16y, 85% (n = 35/41). Patients classified as having a normal fasting tolerance increased with age from 30% in 1-10y, to 36% in 11-16y, and 58% in >16y, but it was unclear if fasting tolerance was biochemically proven. Twenty centres (56%) routinely prescribed uncooked cornstarch (UCCS) to limit overnight fasting in 47 patients regardless of their actual fasting tolerance (37%). All centres advocated an emergency regimen mainly based on glucose polymer for illness management. CONCLUSIONS: Although all patients were prescribed an emergency regimen for illness, use of sucrose and fructose restricted diets with UCCS supplementation varied widely. Restrictions did not relax with age. International guidelines are necessary to help direct future dietary management of FBPase deficiency.
