BackgroundPredictive models based on radiomics features are novel, highly promising approaches for gynaecological oncology. Here, we wish to assess the prognostic value of the newly discovered Radiomic Prognostic Vector (RPV) in an independent cohort of high-grade serous ovarian cancer (HGSOC) patients, treated within a Centre of Excellence, thus avoiding any bias in treatment quality.MethodsRPV was calculated using standardised algorithms following segmentation of routine preoperative imaging of patients (n = 323) who underwent upfront debulking surgery (01/2011-07/2018). RPV was correlated with operability, survival and adjusted for well-established prognostic factors (age, postoperative residual disease, stage), and compared to previous validation models.ResultsThe distribution of low, medium and high RPV scores was 54.2% (n = 175), 33.4% (n = 108) and 12.4% (n = 40) across the cohort, respectively. High RPV scores independently associated with significantly worse progression-free survival (PFS) (HR = 1.69; 95% CI:1.06–2.71; P = 0.038), even after adjusting for stage, age, performance status and residual disease. Moreover, lower RPV was significantly associated with total macroscopic tumour clearance (OR = 2.02; 95% CI:1.56–2.62; P = 0.00647).ConclusionsRPV was validated to independently identify those HGSOC patients who will not be operated tumour-free in an optimal setting, and those who will relapse early despite complete tumour clearance upfront. Further prospective, multicentre trials with a translational aspect are warranted for the incorporation of this radiomics approach into clinical routine.

Identification of families at risk for ovarian cancer offers the opportunity to consider prophylactic surgery thus reducing ovarian cancer mortality. So far, identification of potentially affected families in Germany was solely performed via family history and numbers of affected family members with breast or ovarian cancer. However, neither the prevalence of deleterious variants in BRCA1/2 in ovarian cancer in Germany nor the reliability of family history as trigger for genetic counselling has ever been evaluated.
Prospective counseling and germline testing of consecutive patients with primary diagnosis or with platinum-sensitive relapse of an invasive epithelial ovarian cancer. Testing included 25 candidate and established risk genes. Among these 25 genes, 16 genes (ATM, BRCA1, BRCA2, CDH1, CHEK2, MLH1, MSH2, MSH6, NBN, PMS2, PTEN, PALB2, RAD51C, RAD51D, STK11, TP53) were defined as established cancer risk genes. A positive family history was defined as at least one relative with breast cancer or ovarian cancer or breast cancer in personal history.
In total, we analyzed 523 patients: 281 patients with primary diagnosis of ovarian cancer and 242 patients with relapsed disease. Median age at primary diagnosis was 58 years (range 16-93) and 406 patients (77.6%) had a high-grade serous ovarian cancer. In total, 27.9% of the patients showed at least one deleterious variant in all 25 investigated genes and 26.4% in the defined 16 risk genes. Deleterious variants were most prevalent in the BRCA1 (15.5%), BRCA2 (5.5%), RAD51C (2.5%) and PALB2 (1.1%) genes. The prevalence of deleterious variants did not differ significantly between patients at primary diagnosis and relapse. The prevalence of deleterious variants in BRCA1/2 (and in all 16 risk genes) in patients <60 years was 30.2% (33.2%) versus 10.6% (18.9%) in patients ≥60 years. Family history was positive in 43% of all patients. Patients with a positive family history had a prevalence of deleterious variants of 31.6% (36.0%) versus 11.4% (17.6%) and histologic subtype of high grade serous ovarian cancer versus other showed a prevalence of deleterious variants of 23.2% (29.1%) and 10.2% (14.8%), respectively. Testing only for BRCA1/2 would miss in our series more than 5% of the patients with a deleterious variant in established risk genes.
26.4% of all patients harbor at least one deleterious variant in established risk genes. The threshold of 10% mutation rate which is accepted for reimbursement by health care providers in Germany was observed in all subgroups analyzed and neither age at primary diagnosis nor histo-type or family history sufficiently enough could identify a subgroup not eligible for genetic counselling and testing. Genetic testing should therefore be offered to every patient with invasive epithelial ovarian cancer and limiting testing to BRCA1/2 seems to be not sufficient.

Incidence Patterns and Temporal Trends of Invasive Nonmelanotic Vulvar Tumors in Germany 1999-2011. A Population-Based Cancer Registry Analysis
2015
Time trends on the incidence and characteristics of invasive vulvar cancer in Germany have so far been studied in few local population- and hospital based tumor registries. We aimed to provide an overview on recent developments of vulvar cancer in Germany, using population-based cancer registry data.
We analyzed the data on vulvar cancer of eight population-based German cancer registries for the period 1999-2011. ICD-10 codes and ICD-O-3 morphology codes were used to select site and histologic types. The annual percentage change was calculated on age-adjusted incidence rates with a joinpoint regression model.
A total of 12,711 registered cases of invasive carcinoma of the vulva were included in the analyses, hereof were 12,205 of squamous cell origin. Age-standardized incidence rates of vulvar cancer annually increased by 6.7% (95% confidence limits: 5.6-7.9) from 1.7 per 100,000 women in 1999 to 3.6 per 100,000 women in 2011. An increase was observed among women of all ages, and especially between 30 and 69 years of age.
The annual incidence of invasive carcinoma of the vulva nearly doubled in the past decade in Germany, considerably exceeding the rates observed in other Western European countries. A combination of changes in risk factors, and documentation practice might have contributed to the observed substantial increase in vulvar cancer incidence.

Clinicopathologic and molecular predictors of survival in BRCA-deficient tubo-ovarian high-grade serous carcinoma
2026
BRCA
-associated homologous recombination deficiency (HRD) is present in ~50% of high-grade serous carcinomas (HGSC) and predicts sensitivity to platinum-based therapy. However, there is little understanding of why some patients with
BRCA
-deficient tumors experience poor outcomes. In a large HGSC cohort (n = 1389) including 282 individuals with pathogenic germline
BRCA
variants (g
BRCA
pv), residual disease after primary surgery has limited prognostic effect in g
BRCA
pv-carriers compared to non-carriers, and prognostic outcomes differ based on the mutation location within functional domains of the
BRCA
genes. Multi-omic profiling is performed on 154 tumors, enriched for patients with
BRCA
-deficient tumors that experienced short overall survival ( ≤ 3 years, n = 42). Patients with
BRCA2
-deficient HGSC and loss of
NF1
survive twice as long as those without
NF1
loss, whereas
PIK3CA
,
RAD21
and
MYC
amplification define
BRCA2
-deficient HGSC with exceptionally short survival. Patients with
BRCA1
-deficient HGSC and a more elevated HRD score survive significantly longer.
BRCA1
-deficient tumors in short survivors have evidence of immunosuppressive c-kit signaling and EMT. Our findings confirm that outcome is not determined by
BRCA
status alone, but rather a combination of co-occurring genomic alterations, the extent of DNA repair deficiency, and the tumor-immune microenvironment.
It remains unclear why some BRCA-deficient high-grade serous carcinomas (HGSC) do not respond to platinum-based therapy. Here, multi-omic analysis of BRCA1- and BRCA2-deficient HGSC attributes co-occurring mutations, DNA repair deficiency and tumor microenvironment features to short survival in these patients.

A correlation between the morphology of ovarian high-grade serous carcinomas (HGSOCs) and BRCA mutations has been previously reported.
To investigate, beyond BRCA, the association between the morphology of HGSOC and the presence of homologous recombination deficiency (HRD).
We reviewed 522 of 806 cases of HGSOC from the PAOLA-1 clinical trial, including 163 cases with tumor BRCA mutation, 345 cases without tumor BRCA mutation, and 14 cases with inconclusive BRCA tests. Regarding HRD status (myChoice HRD Plus assay), 269 cases (52%) were positive (HRD+), 198 (38%) negative (HRD-), and 55 (10%) inconclusive. Morphologic analysis included tumor architecture (with more than 25% of solid, pseudoendometrioid, and transitional patterns defining a SET architecture), tumor-infiltrating intraepithelial lymphocytes (ieTILs), and tumor stromal lymphocytes (sTILs).
SET architecture (51% versus 40%, P = .02), high number of ieTILs (16% versus 8%, P = .007), and more than 10% of sTILs (27% versus 18%, P = .02) were associated with tumor BRCA mutation, mostly for tumors with a BRCA1 mutation. These criteria were also associated with HRD status: 54% versus 33% (P < .001) for SET architecture, 14% versus 6% (P = .008) for high number of ieTILs, and 27% versus 15% (P = .003) for more than 10% of sTILs. SET architecture was also significantly associated with HRD+ tumors without tumor BRCA mutation (P < .001) when compared with HRD- tumors. The combination of these 3 criteria showed high specificity (0.99; 95% CI, 0.97-0.99) but low sensitivity (0.07; 95% CI, 0.04-0.10).
The morphology of HGSOC correlates with HRD status and BRCA status but cannot substitute for molecular analysis in daily practice.

Adult ovarian granulosa cell tumors: analysis of outcomes and risk factors for recurrence
2023
ObjectiveAdult granulosa cell tumors represent less than 5% of all ovarian malignancies. The aim of this study was to analyze the clinicopathological parameters and their impact on progression-free and overall survival.MethodsPatients with primary adult granulosa cell tumors treated in three international referral centers between July 1999 and December 2018 were included. The following data were anonymously exported from the prospective database: age at diagnosis, International Federation of Gynecology and Obstetrics (FIGO) stage, adjuvant therapy, surgical procedures, progression-free survival, and overall survival. Descriptive statistical analysis regarding tumor and treatment characteristics was performed. Survival analyses included Kaplan–Meier functions and Cox proportional hazard ratios (HR).ResultsA total of 168 patients with primary adult granulosa cell tumors were included. Median age was 50 years (range 13–82). With regard to stage distribution, 54.2% (n=91) of patients were FIGO stage IA, 1.2% (n=2) were stage IB, 26.8% (n=45) were stage IC, and 17.9% (n=30) were FIGO stage II–IV. 66.7% (n=112) of patients underwent surgical restaging, of whom 17.9% (n=20) were moved to a higher stage. In addition, 36 (21.4%) patients underwent fertility-sparing surgery. After a median follow-up of 61 months (range 0–209), 10.7% of patients (n=18) had recurrent disease and 4.8% (n=8) died of disease. Five-year progression-free survival was 86.1% and estimated overall survival was 95.7%. Five-year progression-free survival was worse for patients with advanced stages (FIGO stage IA/B vs IC: HR 5.09 (95% CI 1.53 to 16.9); FIGO stage IA/B vs II–IV: HR 5.62 (95% CI 1.58 to 19.9)). Nineteen patients receiving adjuvant chemotherapy had lower estimated 5-year progression-free survival compared with patients not receiving chemotherapy (49.7% vs 91.1%, p<0.001; HR 9.15 (95% CI 3.62 to 23.1)).ConclusionThe prognosis of patients with primary adult granulosa cell tumors is mainly determined by FIGO stage. The outcome of patients with FIGO stage IC is comparable to those with advanced stages. Fertility-sparing surgery seems to be a safe procedure in stage IA. Our data do not support the use of adjuvant chemotherapy in early and advanced stages of adult granulosa cell tumors.

Purpose
The chemotherapy response score (CRS) is a histopathological tool to evaluate response to neoadjuvant chemotherapy (NACT) in high-grade serous ovarian cancer (OC). We critically evaluated the clinical value of CRS and compared its predictive power to standard serological (CA125) and radiological response.
Methods
A retrospective analysis of 277 OC patients, who received primary chemotherapy, was performed. CRS, serological, and radiological findings were correlated with progression-free (PFS) and overall survival (OS).
Results
CRS could be determined in 172 of 277 patients (62.1%). In patients with CRS3, a longer median PFS and OS was observed compared with CRS1/2 patients (31.2 vs. 18.9,
P
< 0.001; 55.0 vs. 36.1 months,
P
= 0.050). CA125 and radiological response evaluation were also predictive for PFS and OS. Patients with serological and radiological complete response showed longer PFS (23.0 vs. 14.4,
P
= 0.011; 21.4 vs. 9.6 months,
P
< 0.001) and OS (49.5 vs. 29.0,
P
= 0.003; 45.0 vs. 12.9 months,
P
< 0.001). Patients with pathological complete response (pCR) had the best median PFS (52.8 months), even compared with non-pCR CRS3 (27.8 months). In the total study cohort, serological, and radiological complete response was better at predicting PFS (hazard ratio 2.23 and 2.77).
Conclusion
In this study, evaluation of response to chemotherapy by CRS was not superior to conventional methods (CA125 or radiology). Independent of the evaluation method, response to NACT was predictive of PFS and OS. We observed no added value for CRS as a prognostic marker. The clinical relevance of CRS should be discussed, as no therapeutic consequences result from CRS evaluation.

Cell-free tumor DNA, CA125 and HE4 for the objective assessment of tumor burden in patients with advanced high-grade serous ovarian cancer
2022
The present prospective study aimed at determining the impact of cell-free tumor DNA (ct-DNA), CA125 and HE4 from blood and ascites for quantification of tumor burden in patients with advanced high-grade serous epithelial ovarian cancer (EOC).
Genomic DNA was extracted from tumor FFPE and ct-DNA from plasma before surgery and on subsequent post-surgical days. Extracted DNA was subjected to hybrid-capture based next generation sequencing. Blood and ascites were sampled before surgery and on subsequent post-surgical days. 20 patients (10 undergoing complete resection (TR0), 10 undergoing incomplete resection (TR>0)) were included.
The minor allele frequency (MAF) of TP53 mutations in ct-DNA of all patients with TR0 decreased significantly, compared to only one patient with TR>0. It was not possible to distinguish between patients with TR0 and patients with TR>0, using CA125 and HE4 from blood and ascites.
Based upon the present findings, ct-DNA assessment in patients with high-grade serous EOC might help to better determine disease burden compared to standard tumor markers. Further studies should prospectively evaluate whether this enhancement of accuracy can help to optimize management of patients with EOC.

Purpose
Current guidelines for Lynch syndrome detection in endometrial cancer (EC) patients rely either on risk evaluation, based on personal/family history, or detection of mismatch repair (MMR) deficiency on tumor tissue. We present a combined screening algorithm for Lynch syndrome.
Methods
In this study, 213 consecutive patients treated for EC at Kliniken Essen-Mitte between 2014 and 2018 were included. Personal/family history was evaluated by the Amsterdam II, revised Bethesda/German-DKG criteria and prediction model PREMM
5
. MMR testing was performed by immunohistochemistry (IHC) and/or polymerase chain reaction (PCR) based microsatellite analysis on tumor tissue. MLH1 promoter methylation analysis was performed in case of MLH1 loss or microsatellite instability.
Results
Based on personal/family history 2/213 (Amsterdam II), 31/213 (revised Bethesda/German-DKG) and 149/213 (PREMM
5
) patients were identified as at risk for Lynch syndrome. MMR analysis was performed by IHC in 51.2%, by PCR in 32.4%, and in 16.4% of patients both methods were used. MMR deficiency was detected in 20.6% (44/213). Methylation analysis was performed in 27 patients of whom, 22 (81.4%) showed MLH1 promoter hypermethylation. Only 9% of MMR deficient patients were identified as at risk for Lynch syndrome by the revised Bethesda/German-DKG criteria. A pathogenic germline mutation was discovered in 3 out of 20 patients that underwent genetic testing. None of these patients were younger than 50 years or had a family history of Lynch syndrome-associated malignancies.
Conclusion
General MMR assessment is a feasible strategy to improve the detection of Lynch Syndrome in patients with EC.

Perception of side effects associated with anticancer treatment in women with breast or ovarian cancer (KEM-GO-1): a prospective trial
2020
Purpose
Due to advances in anticancer treatment and supportive care, patients increasingly complained about nonphysical side effects of chemotherapy and targeted therapy in recent years. Therefore, continuous assessment of side effects and patients’ perceptions is important. The aim of this study was to evaluate the identification and severity of side effects perceived by ovarian cancer (OC) and breast cancer (BC) patients undergoing contemporary anticancer therapy.
Methods
Between 2015 and 2017, consecutive chemo-naïve OC and BC patients were enrolled in this prospective cohort study. Interviews were performed 12 ± 3 weeks after start of anticancer therapy, and patients were asked to select and rank, according to severity, 72 physical or nonphysical symptoms potentially related to their treatment. Data were analyzed with descriptive statistics.
Results
Forty-five OC patients and 98 BC patients completed the interview. Sleeping difficulties were ranked as the most troublesome symptom, followed by concerns about family or partner, and loss of hair. Alopecia was the most predominant side effect for BC patients, whereas OC patients were highly afflicted by numbness in limbs. Chemotherapy alone or in combination with targeted therapy caused pronounced sleep disturbances. Prolonged taxane treatment led to shortness of breath and numbness in limbs. Vomiting was ranked by one and nausea by eight women among the five most bothersome symptoms.
Conclusions
Sleep disturbances have lately emerged as the most severe problem in women with OC or BC receiving anticancer therapy. Concerns about family and partner were ranked second in the current study and first in previous investigations.
