Clinical management of borderline tumours of the ovary: results of a multicentre survey of 323 clinics in Germany

The aim of this survey was to analyse the standard of care in diagnostic, surgery, chemotherapy and aftercare management for patients with borderline tumours of the ovary (BOTs) in Germany. A structured questionnaire comprising different dimensions was sent to all 1114 gynaecological departments. The questionnaire could be returned anonymously. The overall response rate was 29.0% (323 departments). Most departments were on secondary care (71.8%), tertiary care (23.2%) or university hospital (5.0%) level. Most clinicians performed not more than five BOT operations (89.2%) per year. Most departments (93.2%) used in addition to classical bimanual examination and vaginal ultrasound, tumour marker CA-125 detection, CT scan, MRI or PET-CT techniques. Departments in university and tertiary care hospitals performed more often a fresh frozen section (87 vs 64%). In young women, clinicians performed much seldom unilateral salpingo-oophorectomy (92%) and only in 53% biopsies of the contralateral ovary. Generally, biopsies of the contralateral ovary were performed in 4–53% of the patients. Chemotherapy was mostly favoured in ‘high-risk' patients with tumour residual, microinvasion or invasive implants. Thus, a high grade of insecurity in diagnostic and therapy of BOT exists in some gynaecological departments and underlines the need for more educational and study activities

Revision of FIGO surgical staging in 2009 for endometrial cancer validates to improve risk stratification

Objective. Correct staging is a cornerstone in cancer treatment. The FIGO surgical staging for endometrial cancer was revised in 2009. We have evaluated if the revision improved stratification with respect to prognosis in a large prospective multicenter setting. Methods. 1268 endometrial cancer patients have been prospectively recruited in the MoMaTEC study for the investigation of clinical and histopathological data. Results. Restaging from FIGO 88 to FIGO 09 criteria increased the number of stage I cases from 932 to 979. The majority of the non-endometrioid tumors, down-staged to FIGO 09 stage!, were of serous histology. One third of the patients classified as stage II tumors based on FIGO 88 criteria (FIGO88 IIA) were down-staged to FIGO 09 IA (53%) and FIGO 09 IB (47%). The histological subtype for these cases was mainly endometrioid (86.1%) and high/intermediate grade (77.7%). Patients with FIGO 88 stages IA, IB, IIA and IIIA with positive cytology only, showed similar survival. In Cox multivariate survival analysis adjusting for histopathological variables we found that the revised FIGO 09 criteria improved prognostication. For FIGO stage I patients the adjusted HR was 3.9 (p = 0.01, Cl 1.35-11.36) for FIGO IB compared to FIGO IA. The independent prognostic impact for the FIGO 09 staging was also confirmed in a subset analysis of patients not subjected to lymphadenectomy and for the endometrioid subgroup. Conclusions. The FIGO 2009 staging system has improved prediction of prognosis, and is less complex, compared to earlier versions. Careful assessment of myometrial invasion seems particularly important for patients not subjected to lymphadenectomy. (C) 2011 Elsevier Inc. All rights reserve

Impact of lymphadenectomy and lymphoedema on health-related quality of life 1 year after surgery for endometrial cancer : A prospective longitudinal multicentre study

Objective To assess the impact of lymphadenectomy and lymphoedema of the lower limbs (LLL) on health-related quality of life (HRQoL) 1 year after surgery for endometrial cancer (EC). Design Prospective longitudinal cohort multicentre study. Setting Departments of obstetrics and gynaecology at four university hospitals, six central hospitals and four county hospitals in Sweden. Population Two-hundred-and-thirty-five women with early stage EC were included; 116 with high-risk EC underwent surgery including lymphadenectomy (+LA), and 119 with low-risk EC had surgery without lymphadenectomy (-LA). Methods The generic SF-36 and EQ-5D-3L and the lymphoedema-specific LYMQOL questionnaire were used to assess HRQoL. LLL was assessed by systematic circumferential measurements of the legs enabling volume estimation, clinical evaluation and patient-reported perception of leg swelling. All assessments were carried out on four occasions; preoperatively, and 4-6 weeks, 6 months and 1 year postoperatively. Main outcome measure HRQoL scores. Results No significant differences were seen in HRQoL between the +LA and -LA groups 1 year postoperatively. Irrespective of method of determining LLL, women with LLL were significantly more affected in the LYMQOL domains Function, Appearance/body image and Physical symptoms, but not in the domain Emotion/mood, than women without LLL. No such differences were seen in the generic HRQoL or in the LYMQOL global score between the groups with and without LLL. Conclusions Lymphadenectomy did not seem to affect generic HRQoL adversely. Irrespective of the method of measuring, LLL affected the lymphoedema-specific HRQoL negatively, mainly in physical domains, but had no impact on the generic HRQoL.

DNA ploidy in curettage specimens identifies high-risk patients and lymph node metastasis in endometrial cancer

Background: Preoperative risk stratification is essential in tailoring endometrial cancer treatment, and biomarkers predicting lymph node metastasis and aggressive disease are aspired in clinical practice. DNA ploidy assessment in hysterectomy specimens is a well-established prognostic marker. DNA ploidy assessment in preoperative curettage specimens is less studied, and in particular in relation to the occurrence of lymph node metastasis. Methods: Curettage image cytometry DNA ploidy in relation to established clinicopathological variables and outcome was investigated in 785 endometrial carcinoma patients prospectively included in the MoMaTEC multicentre trial. Results: Diploid curettage status was found in 72.0%, whereas 28.0% were non-diploid. Non-diploid status significantly correlated with traditional aggressive postoperative clinicopathological features, and was an independent predictor of lymph node metastasis among FIGO stage I–III patients in multivariate analysis (OR 1.94, P=0.033). Non-diploid status was related to shorter disease-specific survival (5-year DSS of 74.4% vs 88.8% for diploid curettage, P<0.001). When stratifying by FIGO stage and lymph node status, the prognostic effect remained. However, in multivariate regression analysis, preoperative histological risk classification was a stronger predictor of DSS than DNA ploidy. Conclusions: Non-diploid curettage is significantly associated with aggressive clinicopathological phenotype, lymph node metastasis, and poor survival in endometrial cancer. The prognostic effect was also observed among subgroups with (presumably) less aggressive traits, such as low FIGO stage and negative lymph node status. Our results indicate curettage DNA ploidy as a possible supplement to existing parameters used to tailor surgical treatment

Asparaginase-like protein 1 expression in curettage independently predicts lymph node metastasis in endometrial carcinoma: a multicentre study

OBJECTIVE: Correct preoperative identification of high-risk patients is important to optimise surgical treatment and improve survival. We wanted to explore if asparaginase-like protein 1 (ASRGL1) expression in curettage could predict lymph node metastases and poor outcome, potentially improving preoperative risk stratification. DESIGN: Multicentre study. SETTING: Ten hospitals in Norway, Sweden and Belgium. POPULATION: Women diagnosed with endometrial carcinoma. METHODS: ASRGL1 expression in curettage specimens from 1144 women was determined by immunohistochemistry. MAIN OUTCOME MEASURES: ASRGL1 status related to disease-specific survival, lymph node status, preoperative imaging parameters and clinicopathological data. RESULTS: ASRGL1 expression had independent prognostic value in multivariate survival analyses, both in the whole patient population (hazard ratio (HR) 1.63, 95% CI 1.11-2.37, P = 0.012) and in the low-risk curettage histology subgroup (HR 2.54, 95% CI 1.44-4.47, P = 0.001). Lymph node metastases were more frequent in women with low expression of ASRGL1 compared with women with high ASRGL1 levels (23% versus 10%, P < 0.001), and low ASRGL1 level was found to independently predict lymph node metastases (odds ratio 2.07, 95% CI 1.27-3.38, P = 0.003). CONCLUSIONS: Low expression of ASRGL1 in curettage independently predicts lymph node metastases and poor disease-specific survival. TWEETABLE ABSTRACT: Low ASRGL1 expression in curettage predicts lymph node metastasis and poor survival in endometrial carcinoma.status: publishe

High-throughput interrogation of PIK3CA, PTEN, KRAS, FBXW7 and TP53 mutations in primary endometrial carcinoma

Objective Endometrial cancer patients may benefit from systemic adjuvant chemotherapy, alone or in combination with targeted therapies. Prognostic and predictive markers are needed, however, to identify patients amenable for these therapies. Methods Primary endometrial tumors were genotyped for > 100 hot spot mutations in genes potentially acting as prognostic or predictive markers. Mutations were correlated with tumor characteristics in a discovery cohort, replicated in independent cohorts and finally, confirmed in the overall population (n = 1063). Results PIK3CA, PTEN and KRAS mutations were most frequently detected, respectively in 172 (16.2%), 164 (15.4%) and 161 (15.1%) tumors. Binary logistic regression revealed that PIK3CA mutations were more common in high-grade tumors (OR = 2.03; P = 0.001 for grade 2 and OR = 1.89; P = 0.012 for grade 3 compared to grade 1), whereas a positive TP53 status correlated with type II tumors (OR = 11.92; P < 0.001) and PTEN mutations with type I tumors (OR = 19.58; P = 0.003). Conversely, FBXW7 mutations correlated with positive lymph nodes (OR = 3.38; P = 0.045). When assessing the effects of individual hot spot mutations, the H1047R mutation in PIK3CA correlated with high tumor grade and reduced relapse-free survival (HR = 2.18; P = 0.028). Conclusions Mutations in PIK3CA, TP53, PTEN and FBXW7 correlate with high tumor grade, endometrial cancer type and lymph node status, whereas PIK3CA H1047R mutations serve as prognostic markers for relapse-free survival in endometrial cancer patients

Preoperative and intraoperative assessment of myometrial invasion in endometrial cancer : A Swedish Gynecologic Cancer Group (SweGCG) study

Introduction Deep myometrial invasion (&amp;gt;= 50%) is a prognostic factor for lymph node metastases and decreased survival in endometrial cancer. There is no consensus regarding which pre/intraoperative diagnostic method should be preferred. Our aim was to explore the pattern of diagnostic methods for myometrial invasion assessment in Sweden and to evaluate differences among magnetic resonance imaging (MRI), transvaginal sonography, frozen section, and gross examination in clinical practice. Material and methods This is a nationwide historical cohort study; women with endometrial cancer with data on assessment of myometrial invasion and FIGO stage I-III registered in the Swedish Quality Registry for Gynecologic Cancer (SQRGC) between 2017 and 2019 were eligible. Data on age, histology, FIGO stage, method, and results of myometrial invasion assessment, pathology results, and hospital level were collected from the SQRGC. The final assessment by the pathologist was considered the reference standard. Results In the study population of 1401 women, 32% (n = 448) had myometrial invasion of 50% of more. The methods reported for myometrial invasion assessment were transvaginal sonography in 59%, MRI in 28%, gross examination in 8% and frozen section in 5% of cases. Only minor differences were found for age and FIGO stage when comparing methods applied for myometrial invasion assessment. The sensitivity, specificity, and accuracy to find myometrial invasion of 50% or more with transvaginal sonography were 65.6%, 80.3%, and 75.8%, for MRI they were 76.9%, 71.9%, and 73.8%, for gross examination they were 71.9%, 93.6%, and 87.3%, and for frozen section they were 90.0%, 92.7%, and 92.0%, respectively. Conclusions In Sweden, the assessment of deep myometrial invasion is most often performed with transvaginal sonography, but the sensitivity is lower than for the other diagnostic methods. In clinical practice, the accuracy is moderate for transvaginal sonography and MRI.Funding Agencies|Swedish Cancer SocietySwedish Cancer Society</p
