RESUMO
The prognostic relevance of circulating tumor cells (CTCs) in breast cancer is well established. However, little is known about the association of CTCs and site of first metastasis. In the SUCCESS A trial, 373 out of 3754 randomized high-risk breast cancer patients developed metastatic disease. CTC status was assessed by the FDA-approved CellSearch®-System (Menarini Silicon Biosystems, Bologna, Italy) in 206 of these patients before chemotherapy and additionally in 159 patients after chemotherapy. CTCs were detected in 70 (34.0%) of 206 patients before (median 2 CTCs, 1-827) and in 44 (27.7%) of 159 patients after chemotherapy (median 1 CTC, 1-124); 16 (10.1%) of 159 patients were CTC-positive at both timepoints. The site of first distant disease was bone-only, visceral-only, and other-site-only in 44 (21.4%), 60 (29.1%), and 74 (35.9%) patients, respectively, while 28 (13.6%) patients had multiple sites of first metastatic disease. Patients with CTCs at both timepoints more often showed bone-only first distant disease (37.5% vs. 21.0%) and first distant disease at multiple sites (31.3% vs. 12.6%) than patients without CTCs before and/or after chemotherapy (p = 0.027). In conclusion, the presence of CTCs before and after chemotherapy is associated with multiple-site or bone-only first-distant disease and may trigger intensified follow-up and perhaps further treatment.
RESUMO
BACKGROUND: Anthracycline/cyclophosphamide-taxane-containing chemotherapy (AC-T) is the standard of care in the adjuvant treatment of HER2-negative early breast cancer (EBC), but recent studies suggest omission of anthracyclines for reduced toxicity without compromising efficacy. METHODS: Based on individual patient data (n = 5924) pooled from the randomised Phase III trials PlanB and SUCCESS C, we compared disease-free survival (DFS) and overall survival (OS) between intermediate to high-risk HER2-negative EBC-patients treated with either six cycles of docetaxel/cyclophosphamide (TC6) or an AC-T regime using univariable and adjusted multivariable Cox regression models. RESULTS: AC-T conferred no significant DFS or OS advantage in univariable (DFS: hazard ratio (HR) for TC vs. AT 1.05, 95% confidence interval (CI): 0.89-1.24, P = 0.57; OS: HR 1.00, 95% CI: 0.80-1.26, P = 1.00) and adjusted multivariable analysis (DFS: HR 1.01, 95% CI: 0.86-1.19, P = 0.91; OS: HR 0.97, 95% CI: 0.77-1.22, P = 0.79). Patients receiving TC6 had significantly fewer grade 3-4 adverse events. Exploratory subgroup analysis showed that AC-T was associated with significantly better DFS and OS in pN2/3 patients, specifically in those with lobular histology. CONCLUSION: For most patients with HER2-negative EBC, AC-T is not associated with a survival benefit compared to TC6. However, patients with lobular pN2/pN3 tumours seem to benefit from anthracycline-containing chemotherapy.

PURPOSE: Evaluation of a novel ultrasound-simulation-app for training fetal echocardiography as a possible useful addition for students, residents and specialist doctors. Furthermore, comparison to a conventional learning-method with special attention on orientation and recognition of physiological structures. METHODS: Prospective two-arm study with the participation of 226 clinical students. 108 students were given an extract from a textbook on fetal echocardiography (PDF-group, n = 108) for 30 min to study. 118 students were able to use the new ultrasound-simulator-app (Simulator-group, n = 118) to learn for 30 min. The knowledge of the students was examined both before and after the learning-period by having them identify sonographic structures in videos using single-choice selection. RESULTS: There were no significant differences between the two groups regarding age (p = 0.87), gender (p = 0.28), and the number of previously performed ultrasound-examinations (p = 0.45). In the Simulator-group, there was a significantly higher learning effect regarding the proportion of students with an increase of correct answers in the video test examination (p = 0.005). At the end of learning, the students in the Simulator-group needed significantly less time to display the structures in the app's simulation (median initially 10.9 s vs. 6.8 s at the end; p < 0.001). CONCLUSIONS: The novel ultrasound-simulation-app seems to be a useful addition and improvement to ultrasound training. Previous difficulties such as simultaneously having patients, ultrasound-machines, and professors at disposal can thus be avoided. This means that another important step towards remote learning can be taken, which has been proven increasingly essential lately, due to the COVID-19 pandemic.

INTRODUCTION: Ki67 as a proliferative marker has prognostic and therapeutic relevance in early breast cancer (EBC). However, standard cutoffs for distinguishing low and high Ki67 do not exist. MATERIAL AND METHODS: Data from all patients treated at the University Hospital Ulm for EBC between January 2013 and December 2015 with documented results for internal Ki67 assessment of the primary (n = 917) tumor were retrospectively analyzed evaluating the associations between Ki67 and other clinicopathological factors. RESULTS: 595 (64.9%) patients had a Ki67 <20% and 322 (35.1%) a Ki67 ≥20%. The median Ki67 was 10% (range 1-90%). Median Ki67 values according to the hormone receptor (HR)/ human epidermal growth factor receptor 2 (HER2) subtypes were 10% for HR-positive/HER2 negative (HR+/HER2-) disease (n = 717), 20% for HR+/HER2+ (n = 76), 30% for HR-/HER2+ (n = 45), and 60% for HR-/HER2- (n = 75). 75.2% or 89.3% of all patients with HER2-positive or triple-negative disease had a Ki67 ≥20%, respectively. Using a multivariable logistic regression with Ki67 (<20% vs. ≥20%) as binary dependent variable, younger age, positive nodal status, higher grading, histological nonspecific type carcinoma, negative HR status, and positive HER2 status were shown to be significantly associated with a higher proliferative index (Ki67 ≥20%). CONCLUSION: This analysis described Ki67 in different subtypes in EBC and its association with clinicopathological factors. According to more aggressive tumor biology, the respective subgroups also showed higher median Ki67 levels. However, definition of low and high proliferation index itself is difficult. It is essential to interpret Ki67 indices carefully with regard to the own institutional values and other clinicopathological factors.

Background Current research in breast cancer focuses on individualization of local and systemic therapies with adequate escalation or de-escalation strategies. As a result, about two-thirds of breast cancer patients can be cured, but up to one-third eventually develop metastatic disease, which is considered incurable with currently available treatment options. This underscores the importance to develop a metastatic recurrence score to escalate or de-escalate treatment strategies. Patients and methods Data from 10,499 patients were available from 17 clinical cancer registries (BRENDA-project [1]. In total, 8566 were used to develop the BRENDA-Index. This index was calculated from the regression coefficients of a Cox regression model for metastasis-free survival (MFS). Based on this index, patients were categorized into very high, high, intermediate, low, and very low risk groups forming the BRENDA-Score. Bootstrapping was used for internal validation and an independent dataset of 1883 patients for external validation. The predictive accuracy was checked by Harrell's c-index. In addition, the BRENDA-Score was analyzed as a marker for overall survival (OS) and compared to the Nottingham prognostic score (NPS). Results: Intrinsic subtypes, tumour size, grading, and nodal status were identified as statistically significant prognostic factors in the multivariate analysis. The five prognostic groups of the BRENDA-Score showed highly significant (p < 0.001) differences regarding MFS:low risk: hazard ratio (HR) = 2.4, 95%CI (1.7-3.3); intermediate risk: HR = 5.0, 95%CI.(3.6-6.9); high risk: HR = 10.3, 95%CI (7.4-14.3) and very high risk: HR = 18.1, 95%CI (13.2-24.9). The external validation showed congruent results. A multivariate Cox regression model for OS with BRENDA-Score and NPS as covariates showed that of these two scores only the BRENDA-Score is significant (BRENDA-Score p < 0.001; NPS p = 0.447). Therefore, the BRENDA-Score is also a good prognostic marker for OS. Conclusion: The BRENDA-Score is an internally and externally validated robust predictive tool for metastatic recurrence in breast cancer patients. It is based on routine parameters easily accessible in daily clinical care. In addition, the BRENDA-Score is a good prognostic marker for overall survival. Highlights: The BRENDA-Score is a highly significant predictive tool for metastatic recurrence of breast cancer patients. The BRENDA-Score is stable for at least the first five years after primary diagnosis, i.e., the sensitivities and specificities of this predicting system is rather similar to the NPI with AUCs between 0.76 and 0.81 the BRENDA-Score is a good prognostic marker for overall survival.
RESUMO
Splenosis is a rare disease, which is often discovered incidentally years after surgical procedures on the spleen or traumatic splenic lesions. Through injury of the splenic capsule, splenic cells are able to spread and autoimplant in a fashion similar to the process of metastatic cancer. Here we present the case of a 62-year-old female patient with a palpable tumor of the lower abdomen. Her medical history was unremarkable, except for splenectomy after traumatic splenic lesion in her childhood. Clinical examination and diagnostic imaging raised the suspicion of advanced ovarian cancer, which was further substantiated by the typical presentation of adnexal masses and disseminated peritoneal metastases during the following staging laparotomy. Surprisingly, we also found peritoneal implants macroscopically similar to splenic tissue. Microscopic examination of tissue specimens by intrasurgical frozen section confirmed the diagnosis of intra-abdominal splenosis. The patient then underwent cytoreductive surgery with complete resection of all cancer manifestations, sparing the remaining foci of splenosis to avoid further morbidity. This case demonstrates the rare coincidence of intra-abdominal carcinoma and splenosis, which could lead to intraoperative difficulties by misinterpreting benign splenic tissue. Therefore, splenosis should be considered in patients with medical history of splenic lesions and further diagnostic imaging like Tc-99m-tagged heat-damaged RBC scan could be used for presurgical distinguishing between tumor spread in the abdominal cavity and disseminated splenosis. The presented case report should not only raise awareness for the rare disease splenosis, but also emphasize the need to consider the possibility of simultaneous incidence of benign and malignant intra-abdominal lesions, as to our knowledge this is the first published case of simultaneous peritoneal carcinomatosis and splenosis.
RESUMO
Reconciliation of family and work life is an important topic for employees. Due to common work in shifts within the health care sector, this is even more essential for health care workers and has great implications in work satisfaction and individuals Ì health. Within all employees of the department of OB/GYN of the German university hospital Ulm, an anonymous and voluntary survey on compatibility of work and family was performed in the summer of 2017. The questionnaires consisted of established and newly designed tools to assess reconciliation of family/work life as well as work-family (WFC) and family-work conflict (FWC). Return rate of questionnaires was 63% (n=136). Physicians (n=33), nurses (n=53), and midwives (n=31) were grouped together as "medical staff" (n=115). There was no significant difference between employees with (n=73) or without children (n=59) regarding WFC and FWC. The group of nurses/midwives and the group of physicians had a significantly higher inter-role conflict (p<0.001) than the group of administrative staff. A negative correlation with "work satisfaction" was found for WFC and FWC. The group of nurses/midwives has significantly higher inter-role conflicts than the administrative staff. Especially the negative correlation of work satisfaction and inter-role conflicts shows the enormous need for improvement in sufficient compatibility of work and family life of employees in the health care sector. This needs to be addressed quickly and effectively as there is an alarming deficit of nurses and midwives in the German health care system.

BACKGROUND: When chemotherapy is indicated in patients with early breast cancer, regimens that contain anthracyclines and taxanes are established standard treatments. Gemcitabine has shown promising effects on the response and prognosis in patients with metastatic breast cancer. The SUCCESS-A trial (NCT02181101) examined the addition of gemcitabine to a standard chemotherapy regimen in high-risk early breast cancer patients. METHODS: A total of 3754 patients with at least one of the following characteristics were randomly assigned to one of the two treatment arms: nodal positivity, tumor grade 3, age ≤ 35 years, tumor larger than 2 cm, or negative hormone receptor status. The treatment arms received either three cycles of 5-fluorouracil, epirubicin, and cyclophosphamide, followed by three cycles of docetaxel (FEC â Doc); or three cycles of FEC followed by three cycles of docetaxel and gemcitabine (FEC â Doc/Gem). The primary study aim was disease-free survival (DFS), and the main secondary objectives were overall survival (OS) and safety. RESULTS: No differences were observed in the 5-year DFS or OS between FEC â Doc and FEC â Doc/Gem. The hazard ratio was 0.93 (95% CI, 0.78 to 1.12; P = 0.47) for DFS and 0.94 (95% CI, 0.74 to 1.19; P = 0.60) for OS. For patients treated with FEC â Doc and FEC â Doc/Gem, the 5-year probabilities of DFS were 86.6% and 87.2%, and the 5-year probabilities of OS were 92.8% and 92.5%, respectively. CONCLUSION: Adding gemcitabine to a standard chemotherapy does not improve the outcomes in patients with high-risk early breast cancer and should therefore not be included in the adjuvant treatment setting. TRIAL REGISTRATION: Clinicaltrials.gov NCT02181101 and EU Clinical Trials Register EudraCT 2005-000490-21. Registered September 2005.

Background The prognostic value of lymph node removal in ovarian cancer varies depending on the tumor stage. While in the advanced stage the removal of clinically normal lymph nodes does not improve the prognosis, this is still unclear in the early stages. Evaluation of the lymph nodes based on preoperative imaging influences the surgical procedure. Methods This retrospective analysis was performed by analyzing data from 114 patients with ovarian cancer, treated in our university hospital in the years 2000â-â2012. Diagnostic performance of imaging by computer tomography with respect to the correct prediction of lymph node status was analyzed in terms of sensitivity, specificity, positive predictive value and negative predictive value. Results Imaging by computer tomography showed a rather limited diagnostic performance with regard to the detection of lymph node metastases in ovarian cancer, with a sensitivity of 40.7%, a specificity of 89.1%, a positive predictive value of 80.0%, and a negative predictive value of 58.3%. A separate analysis for pelvic and paraaortic lymph node involvement showed a better diagnostic performance of computer tomography for the detection of positive paraaortic lymph nodes (41.2, 93.1, 84.0, and 64.3% for sensitivity, specificity, positive predictive value and negative predictive value, respectively) as compared to the detection of positive pelvic lymph nodes (25.6, 91.8, 62.5, and 69.8%). Conclusion The preoperative prediction of lymph node status by computer tomography is limited. A decision for or against lymphadenectomy should not be made solely on the basis of this approach.
RESUMO
BACKGROUND: Nodal status is the most important prognostic factor in cervical cancer. However, further risk stratification in node positive cervical cancer patients is warranted for optimal therapeutic decisions. MATERIAL AND METHODS: Nodal positive patients (n = 86) were retrospectively stratified into two groups according to either number of positive nodes (>3 vs. 1-3) or lymph node ratio (LNR) (≥10 vs. <10% and >6.6 vs. ≤6.6%). Univariable log-rank tests and both univariable and adjusted multivariable Cox regression models were used to evaluate the association between number of positive nodes or LNR and disease-free survival (DFS) and overall survival (OS). RESULTS: LNR was significantly associated with worse DFS in adjusted multivariable analysis, both when categorized as ≥10 versus <10% (HR 2.25, 95% CI 1.06-4.76, p = 0.034) and when categorized as >6.6 versus ≤6.6% (HR 2.79, 95% CI 1.23-6.37, p = 0.015). However, we found no significant association between number of positive nodes or LNR and OS. DISCUSSION: In operable node-positive cervical cancer, both number of positive lymph nodes and LNR can be used for further risk stratification with regard to DFS but not OS.

INTRODUCTION: Large translational research projects may contribute to further progress in cancer treatment by exploring molecular biology, immunologic approaches and identification of new prognostic and predictive factors. Therefore, the BRandOBio-project combines a clinical registry for collection of patient and tumor characteristics with a biobank comprising tumor and liquid biopsies. In addition, sociodemographic, environmental and lifestyle factors of included patients with primary newly diagnosed breast or ovarian cancer, other rare malignant ovarian tumors or gestational trophoblastic disease are prospectively collected. METHODS: The target population includes the German "Alb-Allgäu-Bodensee Region" which constitutes the outreach area of the University Hospital Ulm with affiliated academic centers and private practices. Clinical data combined with primary tumor tissue samples and longitudinal repeatedly collected blood samples [before, 6 (in high-risk situations), 12, 36 and 60 months after treatment and at relapse] will be acquired from more than 4000 patients within the next years. Standardized questionnaires are given to patients of the University Hospital Ulm and eight selected external sites for assessing life style and cancer risk factors. Concomitantly, storage of paraffin-embedded tumor samples as well as liquid biopsy samples will allow translational research projects, for example in terms of investigating circulating DNA and germ line DNA from cell pellets. RESULTS: Starting in January 2016 at the University Hospital Ulm, 19 additional external sites started recruiting patients in March 2017. As of September 15th 2019, 2151 patients with newly diagnosed cancers could be recruited (2044 breast cancer; 107 ovarian cancer). Nearly all patients provided biological samples (tumor and liquid biopsy) and about 80% returned the standardized questionnaire. After 1 year follow-up, blood samples were available from more than 80% of the participating patients. CONCLUSIONS: The BRandO BIO study is a large prospective cohort study with integrated comprehensive biobank and evaluation of sociodemographic and life style factors of gynecological cancer patients in a well-defined geographical area in the South West of Germany. Continuous high patient recruitment and stable rates over 80% for returned questionnaires as well as for repeated blood sampling show high acceptance of the BRandO study program and confirms feasibility of the project.

OBJECTIVE: At the end of the year 2018, a new FIGO classification for cervical cancer was published, mainly revising stage IB and introducing a new stage IIIC, which includes irrespectively of tumor size and local spread all patients with lymph node metastasis. METHODS: We retrospectively analyzed all cases of cervical cancer stage I to IIB who underwent surgery as primary treatment at our institution from 2000 until 2016 and therefore had a histological confirmation of tumor stage. We reclassified all histologies according to the new FIGO classification and calculated outcome according to the new stages. RESULTS: Out of 265 patients, 146 (55%) patients were reclassified into a higher FIGO stage. Most changes appeared within stage IB and from any stage to stage IIIC1. Kaplan-Meier curves for new stages showed a significant difference in disease-free survival (DFS) and overall survival (OS) between stages I versus II versus III (log-rank test, both p < 0.001). Overall, patients that were upstaged had a significant worse DFS (p = 0.012) and OS (p = 0.008) than patients whose stage did not change. Similar observations were made within sub-stages, when node-positive IB or IIB tumors were upstaged to IIIC tumors. CONCLUSION: The new FIGO classification for cervical cancer reflects the strong impact of lymph node metastases on survival and is a clear improvement compared to the old FIGO classification with regard to risk stratification.

BACKGROUND: Medical education is evolving from "learning by doing" to simulation-based hands-on tutorials. OBJECTIVE: The aim of this prospective 2-armed study was to evaluate a newly developed augmented reality ultrasound app and its effect on educational training and diagnostic accuracy. METHODS: We recruited 66 medical students and, using imaging and measuring a kidney as quality indicators, tested them on the time they needed for these tasks. Both groups used textbooks as preparation; in addition, the study group had access to a virtual ultrasound simulation app for mobile devices. RESULTS: There was no significant difference between the study arms regarding age (P=.97), sex (P=.14), and previous ultrasound experience (P=.66). The time needed to complete the kidney measurements also did not differ significantly (P=.26). However, the results of the longitudinal kidney measurements differed significantly between the study and control groups, with larger, more realistic values in the study group (right kidney: study group median 105.3 mm, range 86.1-127.1 mm, control group median 92 mm, range 50.4-112.2 mm; P<.001; left kidney: study group median 100.3 mm, range 81.7-118.6 mm, control group median 85.3 mm, range 48.3-113.4 mm; P<.001). Furthermore, whereas all students of the study group obtained valid measurements, students of the control group did not obtain valid measurements of 1 or both kidneys in 7 cases. CONCLUSIONS: The newly developed augmented reality ultrasound simulator mobile app provides a useful add-on for ultrasound education and training. Our results indicate that medical students' use of the mobile app for training purposes improved the quality of kidney measurements.
RESUMO
Background Peripartal hysterectomy (PH) is a challenging surgical procedure with elevated maternal morbidity. Methods From 2004 to 2016, 41 emergency PHs were performed at the tertiary care center of the Department of Gynecology and Obstetrics at University Hospital Ulm. In our retrospective analysis, the incidence of PH in our hospital was 12.8 per 10,000 deliveries with a maternal mortality of 2.4%. PH followed in 80.5% after cesarean section (c-section). Underlying causes/indications for PH were abnormal placentation (53.7%; n=22), uterine atony (26.8%; n=11), uterine lacerations (14.6%; n=6) and in rare cases uterine infection (4.9%; n=2). The median number of transfused products was 11 packed red blood cells (range 0-55 products), 10 fresh frozen plasma units (range 1-43) and two platelet concentrates (0-16). Results Loss of blood as estimated by surgeons was significantly correlated with actual transfused blood volume (P<0.001). Clinically relevant intra- and/or postoperative complications occurred in 53.7% of patients (n=22). Abnormal placentation was the leading cause for PH with an increased incidence during the last 10 years presumptively representing the elevated rate of c-sections. Conclusion PH goes along with increased rates of blood product transfusions independently of indication for surgery and has a high morbidity with a major complication rate of more than 50%. Prepartal assessment of risk factors like abnormal invasive placenta are crucial for reducing maternal morbidity.

Objective: In the last 5 years there has been much discussion about the surgical procedure for uterine fibroids, and essentially, also uterine sarcoma. Still there exists no reliable presurgical diagnostic tool to differentiate between benign fibroids and uterine sarcomas. The aim of this study was to confirm the suspected association between intraoperative spread of tumor by morcellation and impaired outcomes in patients with sarcoma. Material and Methods: After the local ethics commission positively reviewed the study protocol, the oncologic database of our university hospital was retrospectively reviewed for patients with uterine sarcomas over a time period of 13 years (2002-2015). Data was extracted from the medical files and survival information was collected by contacting the patient's general practitioners if last follow-up-status was older than 6 months. For the analysis, patients were split into two groups with either intrasurgical morcellation (M+) or no morcellation (M-) regarding information provided by the surgical report. Results: Data on 57 patients with uterine sarcoma were available for further analysis. The median age and body mass index of the patients was 63 years and 27 kg/m², respectively. The sarcoma subtypes were 25 leiomyosarcoma, 19 carcinosarcoma, 9 endometrioid stroma sarcoma, 3 adenosarcoma, and one case without further differentiation. In the majority, no morcellation was performed (M- group, n=44) and 51 patients received open surgery (3 laparoscopic, 1 vaginal, and 2 incomplete surgeries). The median time of follow-up was 31 months. The disease-free survival was 50.5 months and the Cox regression analysis showed a hazard ratio of 3.06 [no significant difference between the two subgroups (p=0.079; 95% confidence interval (CI): 0.9-10.6)]. The overall survival was found as 62.2 months and the Cox regression analysis showed a hazard ratio of 3.216 with a statistically significant difference between the two subgroups (p=0.013; 95% CI: 1.3-8.1). Conclusion: Despite the efforts to find a pre-surgical diagnostic tool, the clinical situation remains unsatisfactory. Overall sarcoma prevalence is low during the last 13 years at our university center, but morcellation occurred in a relevant portion of patients (13 of 57). If sarcoma is suspected or diagnosed then en-bloc resection of the uterus can prolong survival. Thus, morcellation of the uterus and not the surgical technique (en-bloc resection) is the prognostic factor and should be avoided in any suspicious case.
RESUMO
BACKGROUND: The prognostic relevance of circulating tumor cells (CTCs) at the time of primary diagnosis has been well established. However, little information is available regarding their prognostic relevance to follow-up care. METHODS: The multicenter, open-label, phase III SUCCESS A trial compared two adjuvant chemotherapy regimens followed by 2 vs 5 years of zoledronate for early-stage, high-risk breast cancer patients. The presence of CTCs was assessed before and 2 years after chemotherapy using the FDA-approved CellSearch System. Overall survival (OS) and disease-free survival (DFS) were analyzed using univariate log-rank tests and multivariable Cox regressions. OS and DFS were measured starting from an assessment of CTCs 2 years after the completion of chemotherapy. All statistical tests were two-sided. RESULTS: The sample included 1087 patients who participated in the translational research program of the SUCCESS A trial and for whom sufficient translational data were available regarding CTC status at baseline and at the 2-year follow-up visit. Two years after chemotherapy, 198 (18.2%) patients were CTC-positive. The median follow-up after this timepoint was 37 months. Cox regressions that included CTC status at baseline revealed that CTC status 2 years after chemotherapy had statistically significant and independent prognostic relevance for OS (hazard ratio [HR] = 3.91, 95% confidence interval [CI] = 2.04 to 7.52, P < .001) and DFS (HR = 2.31, 95% CI = 1.50 to 3.55, P < .001). CONCLUSION: The presence of CTCs 2 years after chemotherapy was associated with decreased OS and DFS. Based on these results, active individualized surveillance strategies for breast cancer survivors based on biomarkers should be reconsidered.

Background Guideline recommendations for axillary surgical approach in breast cancer (BC) treatment changed over the last decade. Methods Data from all invasive BC patients (n = 5344) treated with breast conserving surgery (BCS) at the breast cancer centers of the University Hospital Ulm (U-BCC) and the community hospital Dachau (D-BCC) were included into a retrospective analysis for assessing information on axillary surgery between 2003 and 2016 based on the documented cancer registry data. Results The average annual rate of sentinel node biopsy (SNB) was 85.5% and 87.2% in Ulm and Dachau, respectively. SNB was performed more precisely at the U-BCC with a median of 2.4 resected lymph nodes (LN) compared to a median of 3.2 resected LN in Dachau. Median number of resected LN for axillary lymph node dissection (ALNE) showed a statistically significant reduction over time in Ulm (r s = -â0.82; p < 0.001) and Dachau (r s = -â0.76; p = 0.002). The rate of secondary ALNE (after SNB; 2° ALNE) decreased significantly in U-BCC (r s = -â0.76; p = 0.002) while it remained stable in D-BCC. The influential publication of the Z0011 study in 2010 resulted in a significant reduction of secondary ALNE (24.1% preZ0011 and 14.4% postZ0011; p < 0.001) in Ulm. Conclusion Changes in axillary surgery over time can be seen in the annual statistics of the reviewed BCCs. With BCS, mostly SNB was performed and numbers of removed LN in ALNE have decreased. In the U-BCC, the rate of 2° ALNE dropped after the publication of the Z0011 data. The fact that no such decrease for 2° ALNE was found in D-BCC suggests that university hospitals implement new data and research results into clinical routine earlier than peripheral community hospitals.
RESUMO
BACKGROUND: Despite a trend for less radical surgical approaches in breast cancer due to better understanding of tumour biology and new treatment options such as neoadjuvant chemotherapy (NAC) and intra-operative radiotherapy (IORT), seroma production remains one of the main surgical side effects that can result in prolonged recovery, delay of radiotherapy and patient discomfort. The aim of this study is to provide an update on risk factors for seroma production after breast cancer surgery considering the latest treatment options. METHODS: A retrospective analysis of seroma production in primary breast cancer patients treated between 01.01.2010 and 31.12.2014 at the Breast Cancer Centre, University Hospital Ulm, was performed. Patients with previous breast/axillary surgery or more than one intervention were excluded. Seroma formation was measured using wound drains placed in breast and axilla. RESULTS: In total, 581 patients met the inclusion criteria. Median age at diagnosis was 60 years, and median BMI 25.6 kg/m2. 60 (10.3%) patients had a mastectomy, 175 (30.1%) patients received IORT, and 72 (12.4%) patients received NAC. Median amount of seroma production was 82.5 ml (range 0-3012.5 ml). Multivariate analysis revealed that most of the observed variation in seroma production was due to type of surgery (mastectomy vs. breast conserving), length of surgery and number of removed lymph nodes. Both NAC and IORT explained a significant but very small amount of the observed variation in seroma production. CONCLUSION: The most important factors for seroma production are extent and duration of breast surgery.

BACKGROUND/AIMS: The self-quantification of patients is extending beyond the daily routine. More and more patients ask about the 'optimal' physical condition for an elective surgery. As the hysterectomy is one of the most common surgeries, a literature review was conducted to answer the question for the optimal surgical self preparation (prehabilitation). METHODS: A literature review with the search terms 'physical activity' or 'physical exercise' or 'sport' or 'prehabilitation' and 'hysterectomy' was conducted in the National Library of Medicine database (PubMed) and Web of science. The search was limited to English or German language and publishing date after 2000. Two independent researchers (SO, FE) reviewed the results and excluded irrelevant or double articles. RESULTS: After excluding irrelevant articles, five publications were left for review. One article published a study protocol and one a case report. Three articles reported study results. The numbers of patients reported are low. Prehabilitation programs differ depending on the primary study outcome. There seems to be a benefit for earlier discharge if patients undergo prehabilitation. CONCLUSION: Unlike other disciplines where prehabilitation has been studied, a gynecologic viewpoint still needs establishing and further studies are needed to clarify the benefit for the patients.

Dissemination of tumour cells and the development of solid metastases occurs via blood vessels and lymphatics. Circulating tumour cells (CTCs) and circulating tumour DNA (ctDNA) can be detected in venous blood in patients with early and metastatic breast cancer, and their prognostic relevance has been demonstrated on numerous occasions. Repeated testing for CTCs and ctDNA, or regular so-called "liquid biopsy", can be performed easily at any stage during the course of disease. Additional molecular analysis allows definition of tumour characteristics and heterogeneity that may be associated with treatment resistance. This in turn makes personalised, targeted treatments possible that may achieve both improved overall survival and quality of life.
