Treatment of endometrial cancer from 2000 to 2020 in Germany: a retrospective population based cohort study.

PURPOSE: Endometrial cancer (EC) is one of the most common malignancies among women in western countries. This study aimed to assess data on patient treatment in Germany throughout two decades to evaluate the development and effect of surgery, radiation, and chemotherapy. METHODS: This retrospective registry study included 34,349 EC patients diagnosed between 2000 and 2020. Patients were classified into five risk groups. Overall survival was analyzed by Kaplan-Meier method as well as univariable and multivariable Cox regression to evaluate risk factors and treatment options. RESULTS: Over the study period, minimal invasive surgery was used more often compared to open surgery and was associated with better overall survival. Patients with advanced EC were more likely to receive multimodal therapy. Patients with intermediate risk EC had a good prognosis upon surgery, which further improved when radiotherapy was added. High-risk patients showed poorer prognosis but clearly benefited from additional radiotherapy. Survival of elderly high-risk patients with a non-endometrioid histology was improved when chemotherapy was added to surgery and radiotherapy. CONCLUSION: Our study includes a large analysis of data from German clinical cancer registries on the care of endometrial cancer during two decades. We observed an increase of minimal invasive surgery. There is evidence that minimal invasive surgery is not inferior to open surgery. Adjuvant radio- and chemotherapy further improves survival depending on risk group and age.

Pirfenidone in patients with progressive fibrotic interstitial lung diseases other than idiopathic pulmonary fibrosis (RELIEF): a double-blind, randomised, placebo-controlled, phase 2b trial.

BACKGROUND: Pirfenidone has been shown to slow disease progression in patients with idiopathic pulmonary fibrosis (IPF). However, there are few treatment options for progressive fibrotic interstitial lung diseases (ILDs)) other than IPF. In view of the pathomechanistic and clinical similarities between IPF and other progressive fibrotic ILDs, we aimed to assess the efficacy and safety of pirfenidone in patients with four non-IPF progressive fibrotic ILDs. METHODS: We did a multicentre, double-blind, randomised, placebo-controlled, parallel phase 2b trial (RELIEF) in 17 centres with expertise in ILD in Germany. Eligible participants were patients aged 18-80 years with progressive fibrotic ILD due to four diagnoses: collagen or vascular diseases (ie, connective tissue disease-associated ILDs), fibrotic non-specific interstitial pneumonia, chronic hypersensitivity pneumonitis, or asbestos-induced lung fibrosis. Other eligibility criteria included a forced vital capacity (FVC) of 40-90% predicted, a diffusing capacity of the lung for carbon monoxide of 10-90% predicted, and an annual decline of FVC of at least 5% predicted despite conventional therapy, based on at least three measurements within 6-24 months before enrolment. Patients who had received any previous antifibrotic therapy were excluded. We randomly assigned patients (1:1) to either oral pirfenidone (267 mg three times per day in week 1, 534 mg three times per day in week 2, and 801 mg three times per day thereafter) or matched placebo, added to their ongoing medication. Randomisation was done centrally using permuted block randomisation with varying block sizes stratified by the four diagnostic groups. Patients, investigators, statisticians, monitors, and the study coordinator were masked to treatment assignment until database closure. The placebo-controlled study period was 48 weeks (including up-titration). The primary endpoint was absolute change in percentage of predicted FVC (FVC % predicted) from baseline to week 48 in the intention-to-treat population, with imputation of missing data by the smallest sum of squared differences and attribution of deceased patients to the lowest rank in a rank ANCOVA model. Additionally, we did linear mixed-model repeated measures slope analyses of FVC % predicted longitudinal data over the course of the study as a prespecified sensitivity analysis and post-hoc sensitivity analyses of the primary endpoint in the intention-to-treat population using imputation methods of last observation carried forward [LOCF] and a regression-based multiple imputation procedure. Safety was assessed in all patients who received at least one dose of study medication. This trial is registered with EudraCT 2014-000861-32; DRKS00009822 and is no longer recruiting. FINDINGS: Between April 5, 2016, and Oct 4, 2018, we randomly assigned 127 patients to treatment: 64 to pirfenidone, 63 to placebo. After 127 patients had been randomised, the study was prematurely terminated on the basis of an interim analysis for futility triggered by slow recruitment. After 48 weeks and in the overall population of 127 patients, rank ANCOVA with diagnostic group included as a factor showed a significantly lower decline in FVC % predicted in the pirfenidone group compared with placebo (p=0·043); the result was similar when the model was stratified by diagnostic group (p=0·042). A significant treatment effect was also observed when applying the LOCF and multiple imputation methods to analyses of the primary endpoint. The median difference (Hodges-Lehmann estimate) between pirfenidone and placebo groups for the primary endpoint was 1·69 FVC % predicted (95% CI -0·65 to 4·03). In the linear mixed-model repeated measures slope analysis of FVC % predicted, the estimated difference between treatment and placebo groups from baseline to week 48 was 3·53 FVC % predicted (95% CI 0·21 to 6·86) with imputation of deaths as prespecified, or 2·79 FVC % predicted (95% CI 0·03 to 5·54) without imputation. One death (non-respiratory) occurred in the pirfenidone group (2%) and five deaths (three of which were respiratory) occurred in the placebo group (8%). The most frequent serious adverse events in both groups were infections and infestations (five [8%] in the pirfenidone group, ten [16%] in the placebo group); general disorders including disease worsening (two [3%] in the pirfenidone group, seven [11%] in the placebo group); and cardiac disorders (one ([2%] in the pirfenidone group, 5 [8%] in the placebo group). Adverse events (grade 3-4) of nausea (two patients on pirfenidone, two on placebo), dyspnoea (one patient on pirfenidone, one on placebo), and diarrhoea (one patient on pirfenidone) were also observed. INTERPRETATION: In view of the premature study termination, results should be interpreted with care. Nevertheless, our data suggest that in patients with fibrotic ILDs other than IPF who deteriorate despite conventional therapy, adding pirfenidone to existing treatment might attenuate disease progression as measured by decline in FVC.

Prognostic role of thrombocytosis in recurrent ovarian cancer: a pooled analysis of the AGO Study Group.

PURPOSE: Although thrombocytosis in patients with primary ovarian cancer has been widely investigated, there are only very few data about the role of thrombocytosis in recurrent ovarian cancer. The aim of our study was to investigate the impact of pretreatment thrombocytosis prior to chemotherapy on clinical outcome in patients with recurrent platinum eligible ovarian cancer. METHODS: In our retrospective analysis we included 300 patients who were treated by AGO Study Group Centers within three prospective, randomized phase-III-trials. All patients included had been treatment-free for at least 6 months after platinum-based chemotherapy. We excluded patients who underwent secondary cytoreductive surgery before randomization to the trial. Thrombocytosis was defined as a platelet count of ≥ 400⋅109/L. RESULTS: Pretreatment thrombocytosis was present in 37 out of 300 (12.3%) patients. Patients with thrombocytosis responded statistically significantly less to chemotherapy (overall response rate 35.3% and 41.6%, P = 0.046). The median progression-free survival (PFS) for patients with thrombocytosis was 6.36 months compared to 9.00 months for patients without thrombocytosis (hazard ratio [HR] = 1.19, 95% confidence interval [CI] = 0.84-1.69, P = 0.336). Median overall survival (OS) of patients with thrombocytosis was 16.33 months compared to 23.92 months of patients with a normal platelet count (HR = 1.46, 95% CI = 1.00-2.14, P = 0.047). CONCLUSIONS: The present analysis suggests that pretreatment thrombocytosis is associated with unfavorable outcome with regard to response to chemotherapy and overall survival in recurrent ovarian cancer.

Predicting the course of disease in recurrent vulvar cancer - A subset analysis of the AGO-CaRE-1 study.

OBJECTIVE: In vulvar cancer (VSCC), the course of disease with regard to localization of recurrence and relation of different recurrence sites is poorly described. METHODS: The AGO CaRE-1 study is a retrospective survey of treatment patterns and prognostic factors in vulvar cancer. Patients (pts) with primary VSCC, FIGO stage ≥1B treated in Germany from 1998 to 2008 were included in a centralized database (n = 1618). In the current subgroup analysis, different sites of primary recurrence and their impact on disease course and survival were analyzed using multistate and competing risks methods. RESULTS: 1249 pts with surgical groin staging and known lymph-node status (35.8% N+) were included in the analysis. 360 pts (28.8%) developed disease recurrence; thereof 193 (53.6%) at the vulva only, with a cumulative incidence of 12.6% after 2 years. Generally, prognosis after disease depended on recurrence site: Hazard ratios (HRs) (95% confidence interval) to die for pts with compared to without recurrence at the same time: vulvar only: 5.9 (4.3-8.2); groins only: 6.0 (3.0-10.2); vulvar and groins: 14.1 (7.6-26.4); pelvic/distant: 21.2 (15.3-29.4). Fifty-eight (30.1%) pts with local recurrence developed second recurrence. 2-year mortality after any recurrence was 56.3%. After vulvar recurrence pts had a 2-year and 5-year overall survival rate of 82.2% and 66.9%. CONCLUSIONS: Prognosis after recurrence is highly depending on recurrence site. Pts with isolated vulvar recurrence have an impaired prognosis as many affected pts develop second recurrences.

Impact of EMT in stage IIIB/IV NSCLC treated with erlotinib and bevacizumab when compared with cisplatin, gemcitabine and bevacizumab.

The aim of the present study was to assess the expression of epithelial-mesenchymal transition biomarkers (E-cadherin and vimentin) and their potential significance as prognostic markers in patients with stage IIIB/IV non-squamous non-small cell lung cancer (NSCLC) enrolled in the INNOVATIONS trial, receiving treatment with either erlotinib/bevacizumab (EB) or cisplatin/gemcitabine/bevacizumab (PGB). The tumor tissues of 104 patients were retrospectively analyzed using immunohistochemistry to assess the expression of E-cadherin and vimentin. The distribution between the treatment arms was 46 patients in the EB-arm and 58 in the PGB-arm. Comparing the treatment arms according to E-cadherin and vimentin expression, the analysis revealed that progression-free survival (PFS) was increased in the PGB treatment group when compared with EB treatment in patients with low expression of E-cadherin [hazard ratio (HR)=0.353; 95% confidence interval (CI) 0.189- 0.658; log-rank P=0.0007] and in those with high expression of vimentin [HR=0.276 (95% CI, 0.115- 0.659), log-rank P=0.0021]. In patients that exhibited high E-cadherin and were negative for vimentin, there was no difference in the PFS between the PGB and EB treatment groups. In conclusion, in non-squamous NSCLC with downregulated E-cadherin and upregulated vimentin, the efficacy of chemotherapy with PGB was superior compared with EB; but the same effect was not observed in patients with high E-cadherin and low vimentin. Although increased PFS was observed in patients with PGB treatment compared with EB treatment in the whole analysis populations, in the subgroup of patients with the mesenchymal phenotype, no prognostic or predictive value of either biomarker could be identified. The potential role of bevacizumab in overcoming chemotherapy resistance in the population with the mesenchymal phenotype has to be further explored.

No association between Parkinson disease and autoantibodies against NMDA-type glutamate receptors.

BACKGROUND: IgG-class autoantibodies to N-Methyl-D-Aspartate (NMDA)-type glutamate receptors define a novel entity of autoimmune encephalitis. Studies examining the prevalence of NMDA IgA/IgM antibodies in patients with Parkinson disease with/without dementia produced conflicting results. We measured NMDA antibodies in a large, well phenotyped sample of Parkinson patients without and with cognitive impairment (n = 296) and controls (n = 295) free of neuropsychiatric disease. Detailed phenotyping and large numbers allowed statistically meaningful correlation of antibody status with diagnostic subgroups as well as quantitative indicators of disease severity and cognitive impairment. METHODS: NMDA antibodies were analysed in the serum of patients and controls using well established validated assays. We used anti-NMDA antibody positivity as the main independent variable and correlated it with disease status and phenotypic characteristics. RESULTS: The frequency of NMDA IgA/IgM antibodies was lower in Parkinson patients (13%) than in controls (22%) and higher than in previous studies in both groups. NMDA IgA/IgM antibodies were neither significantly associated with diagnostic subclasses of Parkinson disease according to cognitive impairment, nor with quantitative indicators of disease severity and cognitive impairment. A positive NMDA antibody status was positively correlated with age in controls but not in Parkinson patients. CONCLUSION: It is unlikely albeit not impossible that NMDA antibodies play a significant role in the pathogenesis or progression of Parkinson disease e.g. to Parkinson disease with dementia, while NMDA IgG antibodies define a separate disease of its own.

Cognitive decline in Parkinson's disease: the impact of the motor phenotype on cognition.

OBJECTIVES: Parkinson's disease (PD) is the second most common neurodegenerative disorder and is further associated with progressive cognitive decline. In respect to motor phenotype, there is some evidence that akinetic-rigid PD is associated with a faster rate of cognitive decline in general and a greater risk of developing dementia.The objective of this study was to examine cognitive profiles among patients with PD by motor phenotypes and its relation to cognitive function. METHODS: Demographic, clinical and neuropsychological cross-sectional baseline data of the DEMPARK/LANDSCAPE study, a multicentre longitudinal cohort study of 538 patients with PD were analysed, stratified by motor phenotype and cognitive syndrome. Analyses were performed for all patients and for each diagnostic group separately, controlling for age, gender, education and disease duration. RESULTS: Compared with the tremor-dominant phenotype, akinetic-rigid patients performed worse in executive functions such as working memory (Wechsler Memory Scale-Revised backward; p=0.012), formal-lexical word fluency (p=0.043), card sorting (p=0.006), attention (Trail Making Test version A; p=0.024) and visuospatial abilities (Leistungsprüfungssystem test 9; p=0.006). Akinetic-rigid neuropsychological test scores for the executive and attentive domain correlated negatively with non-tremor motor scores. Covariate-adjusted binary logistic regression analyses showed significant odds for PD-mild cognitive impairment for not-determined as compared with tremor-dominant (OR=3.198) and akinetic-rigid PD (OR=2.059). The odds for PD-dementia were significant for akinetic-rigid as compared with tremor-dominant phenotype (OR=8.314). CONCLUSION: The three motor phenotypes of PD differ in cognitive performance, showing that cognitive deficits seem to be less severe in tremor-dominant PD. While these data are cross-sectional, longitudinal data are needed to shed more light on these differential findings.

ERCC1 assessment in upfront treatment with and without cisplatin-based chemotherapy in stage IIIB/IV non-squamous non-small cell lung cancer.

Prior studies have demonstrated an association between excision repair cross-complementation group 1 (ERCC1) expression level and outcomes in patients with advanced non-small cell lung cancer (NSCLC) treated with platinum-based chemotherapy. The aim of this study was to assess the impact of ERCC1 on survival for patients with stage IIIB/IV non-squamous NSCLC (NS-NSCLC) enrolled in the INNOVATIONS trial, thus receiving as treatment either erlotinib/bevacizumab (EB) or cisplatin/gemcitabine/bevacizumab (PGB). We retrospectively analyzed tumor tissue of 72 patients using immunohistochemistry to assess the expression of ERCC1. The distribution between treatment arms was equal (36 patients each). Two different H scores were calculated and correlated with survival. In ERCC1-positive patients, no significant difference in terms of progression-free survival (PFS) between treatment arms has been detected. ERCC1-negative patients benefited from PGB compared to EB arm (H score: HR = 0.377, 95% CI [0.167-0.849], p = 0.0151; modified H score: HR = 0.484, 95% CI [0.234-1.004], p = 0.0468). With respect to the scoring system, in the EB-arm, a significant superior PFS turned out in ERCC1-positive patients when employing the H-score (HR = 0.430, 95% CI [0.188-0.981], p = 0.0397; median 4.9 vs. 3.9 months), but not with the modified H-score. Our findings support the hypothesis that NS-NSCLC displaying a low ERCC1 expression might benefit from cisplatin-based chemotherapy. High expression indicated better PFS in the EB arm supporting the prognostic impact. However, as impact of ERCC1-assessment even might depend on scoring systems differences, the need in standardization of assessment methodology is emphasized.

A GATA3-specific DNAzyme attenuates sputum eosinophilia in eosinophilic COPD patients: a feasibility randomized clinical trial.

BACKGROUND: A subset of COPD-patients presents with eosinophilic airway inflammation. While treatment of asthmatic patients with the GATA3-specific DNAzyme SB010 attenuated sputum eosinophilia after allergen challenge, this specific treatment has not been evaluated in patients with COPD. Our objective was to evaluate the feasibility and safety of inhaled SB010 in COPD patients with sputum eosinophilia. METHODS: We conducted a randomized, double-blind, placebo-controlled, multicentre clinical trial in COPD-patients with sputum eosinophilia (≥2.5% non-squamous cells). Patients inhaled 10 mg SB010 bid or matching placebo via the controlled inhalation system AKITA2 APIXNEB for 28 days. Endpoints included the feasibility of the study (primary), patient's safety, sputum eosinophils, FENO, lung function, symptoms, and biomarkers. The study was registered in the German Clinical Trials Register: DRKS00006087. RESULTS: One hundred thirty patients were screened, 23 patients were randomized (FEV1 49.4 ± 11.5%; sputum eosinophils 8.0 ± 8.4%) and 19 patients completed the study (10 placebo, 9 SB010. After 28 days, SB010 decreased the relative sputum eosinophil count (p = 0.004) as compared to no changes in placebo-treated patients. FENO, lung function, and symptoms were not affected significantly. We found an increase in blood IFN-γ (p = 0.02) and a trend to lower IL-5 levels in patients treated with SB010. SB010 was safe and well tolerated. Thirty five AEs (22 SB010, 13 placebo including 1 SAE) were observed with 3 AEs in each group judged to be possibly treatment-related. CONCLUSION: In patients with eosinophilic COPD, sputum eosinophils could be reduced by inhalation of SB010. Long-term studies are needed to demonstrate clinical efficacy.

Exploring efficacy and safety of oral Pirfenidone for progressive, non-IPF lung fibrosis (RELIEF) - a randomized, double-blind, placebo-controlled, parallel group, multi-center, phase II trial.

BACKGROUND: Pirfenidone is currently approved in the EU for the treatment of mild to moderate idiopathic pulmonary fibrosis (IPF) and offers a beneficial risk-benefit profile. However, there are several other, progressive fibrotic lung diseases, in which conventional anti-inflammatory therapy is not sufficiently effective and antifibrotic therapies may offer a novel treatment option. METHODS/DESIGN: We designed a study protocol for inclusion of patients with progressive fibrotic lung disease despite conventional anti-inflammatory therapy (EudraCT 2014-000861-32). The study population comprises patients with collagen-vascular disease-associated lung fibrosis (CVD-LF), fibrotic non-specific interstitial pneumonia (fNSIP), chronic hypersensitivity pneumonitis (cHP), and asbestos-related lung fibrosis (ALF). Disease progression needs to be proven by slope calculation of at least three Forced Vital Capacity (FVC) values obtained within 6-24 months prior to inclusion, documenting an annualized decline in percent predicted FVC of 5% (absolute) or more despite appropriate conventional therapy. Absolute change in percent predicted FVC from baseline - analyzed using a rank analysis of covariance (ANCOVA) model - will serve as efficacy-related primary study endpoint. DISCUSSION: There is an urgent unmet clinical need for effective therapies for patients with a progressive fibrotic lung disease other than IPF. The current study protocol is unique with respect to selecting patients with different disease entities of lung fibrosis which have, however, essential pathophysiological characteristics in common. Moreover, by selecting patients with evidence of disease progression despite conventional therapy, the protocol ensures that a cohort of interstitial lung disease (ILD) patients with a high unmet medical need is targeted and it may allow a sufficiently high event rate for evaluation of treatment responses.

Propensity Scoring after Multiple Imputation in a Retrospective Study on Adjuvant Radiation Therapy in Lymph-Node Positive Vulvar Cancer.

Propensity scoring (PS) is an established tool to account for measured confounding in non-randomized studies. These methods are sensitive to missing values, which are a common problem in observational data. The combination of multiple imputation of missing values and different propensity scoring techniques is addressed in this work. For a sample of lymph node-positive vulvar cancer patients, we re-analyze associations between the application of radiotherapy and disease-related and non-related survival. Inverse-probability-of-treatment-weighting (IPTW) and PS stratification are applied after multiple imputation by chained equation (MICE). Methodological issues are described in detail. Interpretation of the results and methodological limitations are discussed.

Role of tumour-free margin distance for loco-regional control in vulvar cancer-a subset analysis of the Arbeitsgemeinschaft Gynäkologische Onkologie CaRE-1 multicenter study.

AIM OF THE STUDY: A tumour-free pathological resection margin of ≥8 mm is considered state-of-the-art. Available evidence is based on heterogeneous cohorts. This study was designed to clarify the relevance of the resection margin for loco-regional control in vulvar cancer. METHODS: AGO-CaRE-1 is a large retrospective study. Patients (n = 1618) with vulvar cancer ≥ FIGO stage IB treated at 29 German gynecologic-cancer-centres 1998-2008 were included. This subgroup analysis focuses on solely surgically treated node-negative patients with complete tumour resection (n = 289). RESULTS: Of the 289 analysed patients, 141 (48.8%) had pT1b, 140 (48.4%) pT2 and 8 (2.8%) pT3 tumours. One hundred twenty-five (43.3%) underwent complete vulvectomy, 127 (43.9%) partial vulvectomy and 37 (12.8%) radical local excision. The median minimal resection margin was 5 mm (1 mm-33 mm); all patients received groin staging, in 86.5% with full dissection. Median follow-up was 35.1 months. 46 (15.9%) patients developed recurrence, thereof 34 (11.8%) at the vulva, after a median of 18.3 months. Vulvar recurrence rates were 12.6% in patients with a margin <8 mm and 10.2% in patients with a margin ≥8 mm. When analysed as a continuous variable, the margin distance had no statistically significant impact on local recurrence (HR per mm increase: 0.930, 95% CI: 0.849-1.020; p = 0.125). Multivariate analyses did also not reveal a significant association between the margin and local recurrence neither when analysed as continuous variable nor categorically based on the 8 mm cutoff. Results were consistent when looking at disease-free-survival and time-to-recurrence at any site (HR per mm increase: 0.949, 95% CI: 0.864-1.041; p = 0.267). CONCLUSIONS: The need for a minimal margin of 8 mm could not be confirmed in the large and homogeneous node-negative cohort of the AGO-CaRE database.

Apolipoprotein E ε4 does not affect cognitive performance in patients with Parkinson's disease.

INTRODUCTION: Cognitive impairment is a common and disabling non-motor symptom in Parkinson's disease (PD). The apolipoprotein E (APOE) allele ε4 is a known risk factor for Alzheimer's disease and has also been suggested to be a risk factor for dementia in PD and even a predictor of impairment in certain cognitive domains. METHODS: A total of 447 PD patients (PD patients without cognitive impairment: n = 187; PD patients with mild cognitive impairment: n = 188; PD patients with dementia: n = 72) were included from an ongoing observational German multicenter cohort study (LANDSCAPE study). All patients underwent an extensive neuropsychological test battery, including assessments of memory, visuospatial functioning, attention, language, and executive function. APOE genotype was determined by an allelic discrimination assay. Linear regression analysis was used to explore the associations between APOE-ε4 and cognitive performance. RESULTS: The APOE-ε4 allele was not associated with a diagnosis of cognitive impairment in PD (PD with mild cognitive impairment and PD with dementia) or with deficits in specific neuropsychological domains in our study cohort. CONCLUSION: Our data question the relevance of the APOE-ε4 allele as a predictor of cognitive impairment in PD.

Temsirolimus in women with platinum-refractory/resistant ovarian cancer or advanced/recurrent endometrial carcinoma. A phase II study of the AGO-study group (AGO-GYN8).

OBJECTIVES: To evaluate activity and toxicity of mTOR inhibitor temsirolimus in patients with platinum-refractory/resistant ovarian cancer (OC) or advanced/recurrent endometrial carcinoma (EC). METHODS: Women with epithelial ovarian, fallopian tube or primary peritoneal cancer were eligible, when they had progression during treatment with a platinum based regimen or within 6 months after receiving a platinum based regimen and a previous taxane treatment. Women with advanced/recurrent EC, no longer amenable to curative surgery and/or radiotherapy were eligible when they had no previous or only adjuvant chemotherapy. Preceding endocrine therapy for metastatic/recurrent disease was allowed. Patients received weekly IV infusions of 25mg temsirolimus. Primary endpoint was progression free survival rate after 4 months (OC) or 6 months (EC). A two stage design was applied. RESULTS: Forty-four patients (OC: n=22; EC: n=22) were enrolled and received temsirolimus treatment. Median age was 56 years (OC) or 63 years (EC). After eight weeks of treatment, 10 of 21 evaluable patients in the OC cohort and 8 of 20 evaluable patients in the EC cohort had progressive disease. Thus efficacy did not meet the predefined levels during the first stage of recruitment and the trial was stopped. Some patients in both cohorts had long lasting PFS (>7 months). Toxicity of temsirolimus was mild. CONCLUSIONS: Temsirolimus treatment was well tolerated in our patients, but did not meet the predefined efficacy criteria. In our study as in other trials on rapalogs in OC or EC, a few patients had long lasting disease stabilisations.

Adjuvant therapy in lymph node-positive vulvar cancer: the AGO-CaRE-1 study.

BACKGROUND: Women with node-positive vulvar cancer have a high risk for disease recurrence. Indication criteria for adjuvant radiotherapy are controversial. This study was designed to further understand the role of adjuvant therapy in node-positive disease. METHODS: Patients with primary squamous-cell vulvar cancer treated at 29 gynecologic cancer centers in Germany from 1998 through 2008 were included in this retrospective exploratory multicenter cohort study. Of 1618 documented patients, 1249 had surgical groin staging and known lymph node status and were further analyzed. All statistical tests were two-sided. RESULTS: Four hundred forty-seven of 1249 patients (35.8%) had lymph node metastases (N+). The majority of N+ patients had one (172 [38.5%]) or two (102 [22.8%]) positive nodes. The three-year progression-free survival (PFS) rate of N+ patients was 35.2%, and the overall survival (OS) rate 56.2% compared with 75.2% and 90.2% in node-negative patients (N-). Two hundred forty-four (54.6%) N+ patients had adjuvant therapy, of which 183 (40.9%) had radiotherapy directed at the groins (+/-other fields). Three-year PFS and OS rates in these patients were better compared with N+ patients without adjuvant treatment (PFS: 39.6% vs 25.9%, hazard ratio [HR] = 0.67, 95% confidence interval [CI[= 0.51 to 0.88, P = .004; OS: 57.7% vs 51.4%, HR = 0.79, 95% CI = 0.56 to 1.11, P = .17). This effect was statistically significant in multivariable analysis adjusted for age, Eastern Cooperative Oncology Group, Union internationale contre le cancer stage, grade, invasion depth, and number of positive nodes (PFS: HR = 0.58, 95% CI = 0.43 to 0.78, P < .001; OS: HR = 0.63, 95% CI = 0.43 to 0.91, P = .01). CONCLUSION: This large multicenter study in vulvar cancer observed that adjuvant radiotherapy was associated with improved prognosis in node-positive patients and will hopefully help to overcome concerns regarding adjuvant treatment. However, outcome after adjuvant radiotherapy remains poor compared with node-negative patients. Adjuvant chemoradiation could be a possible strategy to improve therapy because it is superior to radiotherapy alone in other squamous cell carcinomas.
