ObjectivesBenign leiomyomas are the most common uterine tumors. In contrast, uterine leiomyosarcomas are malignancies with a poor prognosis due to difficulties in early diagnosis and inappropriate surgical treatment. Most often they are diagnosed incidentally after surgery performed for treatment of leiomyoma. As the appropriate surgical treatment is crucial for survival of the patient, there is a high demand to predict leiomyosarcoma pre-operatively. Available scoring systems to discriminate leiomyoma from leiomyosarcoma are based on retrospective studies with limited numbers of patients and are not implemented in routine clinical practice.MethodsThe aim of our study was to evaluate a recently published score—the pre-operative leiomyosarcoma (pLMS) score—to determine whether it would have been predictive of leiomyosarcoma in 177 patients from the NOGGO-REGSA study, a German register of histologically proven gynecological sarcoma detected during routine clinical investigation.ResultsThe threshold of the pLMS score for ‘leiomyosarcoma not probable’ (< −3) failed for 7.5% of the patients and the threshold ‘indicator for leiomyosarcoma’ (>+1) was true for 39.1% of the patients. 53.4% of the patients were attributed to the group ‘additional investigations are recommended’ (−3 to +1). The most relevant parameters in our analysis were suspicious sonography and rapid growth, but neither have been quantitatively defined.ConclusionIn our validation cohort, the pLMS score seems not to be a reliable tool to predict leiomyosarcoma and therefore we do not recommend its clinical implementation to identify leiomyosarcoma.

BackgroundMedications from Anthroposophical Medicine (AM) are clinically used for the treatment of infections within a whole medical system but have not yet been evaluated regarding antibacterial effects. The aims of this study was to investigate antibacterial activity of AM medications in cell culture.MethodsScreening of AM drug registers for preparations used to treat any kind of infection and being available in dilutions ≤ D2 and without alcoholic content. Selected medications were screened for antimicrobial activity against Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa using the agar diffusion method. For antimicrobial active preparations growth kinetics (drop plate method) and minimal inhibitory concentrations (MIC, macrodilution method) were determined.ResultsThirty-three preparations matched the selection criteria and were chosen for own experiments. One of them (Berberis Decoctum D2) exhibited bactericidal activities against Bacillus subtilis and Staphylococcus aureus, including methicillin resistant strains. The MIC could be determined as 5 mg/ml. The effects could be related to the content of berberine in the extract. No activity towards gram-negative bacteria was found. The other tested extracts had no antibacterial effects.ConclusionBerberis Decoctum D2 which is used in AM to treat infections exhibits bactericidal effects on Staphylococcus aureus, including methicillin resistant strains.

Background Malignant sex cord‐stromal cell tumours (SCST) account for only 7% of ovarian malignancies. The Arbeitsgemeinschaft fuer Gynaekologische Onkologie (AGO) study group has established a clinicopathological database to provide an overview of the current treatment strategies and survival of SCST patients and to identify research needs. Methods Twenty centres provided mixed retro‐ and prospective data of patients with tumour specimens and second‐opinion pathology review treated between 2000 and 2014. Descriptive analyses of treatment strategies, Kaplan–Meier curves and cox regression analyses were conducted. Results Two hundred and sixty‐two SCST patients were included. One hundred and ninety‐one Granulosa‐cell tumour (GCT) and 17 Sertoli‐Leydig cell tumour (SLCT) patients were stage I disease (>80%). Forty four GCT (18.7%) and two (8.3%) SLCT patients received adjuvant systemic treatment. After a median observation time of 78.2 months, 46% of all SCST patients experienced disease recurrence, treated predominantly with secondary debulking surgery (> 90%). Advanced FIGO stage, lymph node involvement and intra‐operative capsule rupture were associated with disease recurrence on univariate analysis (all p < 0.05). Median OS time was not reached. Discussion In this analysis of SCST patients, adjuvant chemotherapy was unable to prevent disease recurrence. Despite high recurrence rates, overall survival rates were excellent.

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.
