ABSTRACT
Introduction: Studies have shown that pregnant women with COVID-19 have a higher risk of intensive care unit admission and invasive mechanical ventilation support than non-pregnant women. Pregnancy-associated physiological changes in respiratory function may contribute to the elevated risk. Alteration in lung volumes and capacities are attributed to the mechanical impediment caused by the growing fetus. Multiple pregnancies may therefore compromise functional lung capacity earlier than singleton pregnancies and contribute to severe respiratory symptoms of COVID-19. Materials and Methods: A total of 5514 women with a symptomatic SARS-CoV-2 infection during pregnancy registered in the COVID-19 Related Obstetric and Neonatal Outcome Study were included. The COVID-19-related adverse maternal outcomes were compared in 165 multiple versus 5349 singleton pregnancies. Combined adverse maternal outcome was defined as presence of COVID-19-related hospitalization and/or pneumonia and/or oxygen administration and/or transfer to ICU and/or death. Multivariate logistic regression was used to estimate the odds ratios and 95% confidence intervals were calculated. Results: The frequency of dyspnea, likelihood of developing dyspnea in a defined pregnancy week and duration of the symptomatic phase of the COVID-19 infection did not differ between the two groups. On average, COVID-19-related combined adverse outcome occurred earlier during pregnancy in women expecting more than one child than in singleton pregnancies. The overall incidence of singular and combined COVID-19-associated adverse maternal outcomes was not significantly different between groups. However, regression analysis revealed that multiple gestation, preconceptional BMI > 30 kg/m 2 and gestational age correlated significantly with an increased risk of combined adverse maternal outcome. Conversely, maternal age and medically assisted reproduction were not significant risk factors for combined adverse maternal outcome. Conclusion: Our data show that multiple gestation alone is a risk factor for COVID-19-associated combined adverse maternal outcome. Moreover, severe courses of COVID-19 in women expecting more than one child are observed earlier in pregnancy than in singleton pregnancies.
ABSTRACT
OBJECTIVE: Gynecological sarcomas account for 3% of all gynecological malignancies and are associated with a poor prognosis. Due to the rarity and heterogeneity of gynecological sarcomas there is still no consensus on optimal therapeutic strategies. This study's objective was to describe the treatment strategies used in patients with gynecological sarcomas in the primary course of disease. METHODS: The German prospective registry for gynecological sarcoma (REGSA) is the largest registry for gynecological sarcomas in Germany, Austria and Switzerland. Primary inclusion criteria for REGSA are histological diagnosis of sarcoma of the female genital tract, sarcoma of the breast or uterine smooth muscle tumors of uncertain malignant potential (STUMP). We evaluated data of the REGSA registry on therapeutic strategies used for primary treatment from August 2015 to February 2021. RESULTS: A total of 723 patients from 120 centers were included. Data on therapeutic strategies for primary treatment were available in 605 cases. Overall, 580 (95.9%) patients underwent primary surgery, 472 (81.4%) of whom underwent only hysterectomy. Morcellation was reported in 11.4% (n=54) of all hysterectomies. A total of 42.8% (n=202) had no further surgical interventions, whereas an additional salpingo-ophorectomy was performed in 54% (n=255) of patients. An additional lymphadenectomy was performed in 12.7% (n=60), an omentectomy in 9.5% (n=45) and intestinal resection in 6.1% (n=29) of all patients. Among 448 patients with available information, 21.4% (n=96) received chemo- or targeted therapies, more commonly as single-agent treatment than as drug combinations. Information about anti-hormonal treatment was available for 423 patients, among which 42 (9.9%) received anti-hormonal treatment, 23 (54.8%) of whom with low-grade endometrial stroma sarcomas. For radiotherapy, data of 437 patients were available, among which 29 (6.6%) patients underwent radiotherapy. CONCLUSION: Our study showed that treatment of patients with gynecologic sarcomas is heterogeneous. Further trials are needed along with more information on treatment modalities, therapy response and patient-reported outcomes to implement new treatment strategies.

ABSTRACT
Introduction To date, the optimal axillary staging procedure for initially node-positive breast carcinoma patients after neoadjuvant chemotherapy (NACT) has been unclear. The aim of the AXSANA study is to prospectively compare different surgical staging techniques with respect to the oncological outcome and quality of life for the patients. Little is known about current clinical practice in Germany. Material and Methods In this paper we analyzed data from patients enrolled in the AXSANA study at German study sites from June 2020 to March 2022. Results During the period under investigation, 1135 patients were recruited at 143 study sites. More than three suspicious lymph nodes were initially found in 22% of patients. The target lymph node (TLN) was marked in 64% of cases. This was done with clips/coils in 83% of patients, with magnetic seeds or carbon suspension in 8% each, and with a radar marker in 1% of patients. After NACT, targeted axillary dissection (TAD) or axillary lymphadenectomy (ALND) were each planned in 48% of patients, and sentinel lymph node biopsy alone (SLNB) in 2%. Clinically, the nodal status after NACT was found to be unremarkable in 65% of cases. Histological lymph node status was correctly assessed by palpation in 65% of patients and by sonography in 69% of patients. Conclusion At the German AXSANA study sites, TAD and ALND are currently used as the most common surgical staging procedures after NACT in initially node-positive breast cancer patients. The TLN is marked with various markers prior to NACT. Given the inadequate accuracy of clinical assessment of axillary lymph node status after NACT, it should be questioned whether axillary dissection after NACT should be performed based on clinical assessment of nodal status alone.
ABSTRACT
BACKGROUND: The impact of comprehensive pelvic and para-aortic lymphadenectomy on survival in patients with stage I or II endometrial cancer with a high risk of recurrence is not reliably documented. The side effects of this procedure, including lymphedema and lymph cysts, are evident. PRIMARY OBJECTIVE: Evaluation of the effect of comprehensive pelvic and para-aortic lymphadenectomy in the absence of bulky nodes on 5 year overall survival of patients with endometrial cancer (International Federation of Gynecology and Obstetrics (FIGO) stages I and II) and a high risk of recurrence. STUDY HYPOTHESIS: Comprehensive pelvic and para-aortic lymphadenectomy will increase 5 year overall survival from 75% (no lymphadenectomy) to 83%, corresponding to a hazard ratio of 0.65. TRIAL DESIGN: Open label, randomized, controlled trial. In arm A, a total hysterectomy plus bilateral salpingo-oophorectomy is performed. In arm B, in addition, a systematic pelvic and para-aortic lymphadenectomy up to the level of the left renal vein is performed. For all patients, vaginal brachytherapy and adjuvant chemotherapy (carboplatin/paclitaxel) are recommended. MAJOR INCLUSION CRITERIA: Patients with histologically confirmed endometrial cancer stages pT1b-pT2, all histological subtypes, and pT1a endometrioid G3, serous, clear cell, or carcinosarcomas can be included when bulky nodes are absent. When hysterectomy has already been performed (eg, for presumed low risk endometrial cancer), study participation is also possible. EXCLUSION CRITERIA: Patients with pT1a, G1 or 2 of type 1 histology or uterine sarcomas (except for carcinosarcomas), endometrial cancers of FIGO stage III or IV (except for microscopic lymph node metastases) or visual extrauterine disease. PRIMARY ENDPOINT: Overall survival calculated from the date of randomization until death. SAMPLE SIZE: 640 patients will be enrolled in the study. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: At present, 252 patients have been recruited. Based on this, accrual should be completed in 2025. Results should be presented in 2031. TRIAL REGISTRATION: NCT03438474.

BACKGROUND & AIMS: Ketogenic diets (KDs) have been proposed as complementary nutritional treatments for cancer patients. Because it is important to gain knowledge about the safety of KDs adopted during cancer therapy, we studied the effects of KDs on quality of life and blood parameters in women with early-stage breast cancer undergoing radiotherapy. METHODS: A total of 29 patients consuming a KD were compared to 30 patients consuming their standard diet (SD) with respect to EORTC-QLQ30 questionnaire scores and different metabolic and hormonal blood parameters that were obtained prior to, in the middle of and at the end of radiotherapy. Baseline-to-end differences were assessed using Wilcoxon tests, and longitudinal changes were analyzed using linear mixed effects models. RESULTS: Compared to the SD, women consuming a KD experienced significant improvements in emotional functioning, social functioning, sleep quality, future perspectives and systemic therapy side effects (all p-values <0.01). While breast symptoms increased significantly in both groups, the increase was less pronounced in the KD group. There was no hint of a detrimental effect of the KDs on either liver or kidney function; in contrast, biomarkers of metabolic health (gamma-glutamyl-transpeptidase, creatinine, triglycerides, IGF-1, free T3) significantly improved in the KD, but not the SD group. CONCLUSIONS: These data support the hypothesis that consuming a KD during radiotherapy is safe for women with breast cancer and has the potential to improve quality of life and metabolic health.

Evolutionary principles are rarely considered in clinical oncology. We here aimed to test the feasibility and effects of a dietary and physical activity intervention based on evolutionary considerations in an oncological setting. A total of 13 breast cancer patients referred to our clinic for curative radiotherapy were recruited for this pilot study. The women were supposed to undertake a "Paleolithic lifestyle" (PL) intervention consisting of a Paleolithic diet and daily outdoor activity of at least 30 min duration while undergoing radiotherapy. Body composition was measured weekly by bioimpedance analysis. Blood parameters were assessed before, during, and at the end of radiotherapy. A control group on an unspecified standard diet (SD) was assigned by propensity score matching. A total of eleven patients completed the study. The majority of patients (64%) reported feeling good or very good during the intervention. The intervention group experienced an average decrease of 0.4 kg body weight (p < 0.001) and 0.34 kg (p < 0.001) fat mass per week, but fat-free and skeletal muscle mass were not significantly affected. Vitamin D levels increased slightly from 23.8 (11-37.3) ng/ml to 25.1 (22.6-41.6) ng/ml (p = 0.053). ß-hydroxybutyrate levels were significantly increased and triglycerides and free T3 hormone levels significantly reduced by the PL intervention. This pilot study shows that adoption of a PL intervention during curative radiotherapy of breast cancer patients is feasible and able to reduce fat mass. Daily outdoor activity could eliminate vitamin D deficiency (vitamin D < 20 ng/ml). Future studies are needed to confirm these findings.

BACKGROUND: Patients with metastatic breast cancer (MBC) are treated with a palliative approach with focus on controlling for disease symptoms and maintaining high quality of life. Information on individual needs of patients and their relatives as well as on treatment patterns in clinical routine care for this specific patient group are lacking or are not routinely documented in established Cancer Registries. Thus, we developed a registry concept specifically adapted for these incurable patients comprising primary and secondary data as well as mobile-health (m-health) data. METHODS: The concept for patient-centered "Breast cancer care for patients with metastatic disease" (BRE-4-MED) registry was developed and piloted exemplarily in the region of Main-Franconia, a mainly rural region in Germany comprising about 1.3 M inhabitants. The registry concept includes data on diagnosis, therapy, progression, patient-reported outcome measures (PROMs), and needs of family members from several sources of information including routine data from established Cancer Registries in different federal states, treating physicians in hospital as well as in outpatient settings, patients with metastatic breast cancer and their family members. Linkage with routine cancer registry data was performed to collect secondary data on diagnosis, therapy, and progression. Paper and online-based questionnaires were used to assess PROMs. A dedicated mobile application software (APP) was developed to monitor needs, progression, and therapy change of individual patients. Patient's acceptance and feasibility of data collection in clinical routine was assessed within a proof-of-concept study. RESULTS: The concept for the BRE-4-MED registry was developed and piloted between September 2017 and May 2018. In total n = 31 patients were included in the pilot study, n = 22 patients were followed up after 1 month. Record linkage with the Cancer Registries of Bavaria and Baden-Württemberg demonstrated to be feasible. The voluntary APP/online questionnaire was used by n = 7 participants. The feasibility of the registry concept in clinical routine was positively evaluated by the participating hospitals. CONCLUSION: The concept of the BRE-4-MED registry provides evidence that combinatorial evaluation of PROMs, needs of family members, and raising clinical parameters from primary and secondary data sources as well as m-health applications are feasible and accepted in an incurable cancer collective.
ABSTRACT
One of the most common adverse events (AEs) occurring during treatment with aromatase inhibitors (AIs) is musculoskeletal pain. The aim of our study was to analyze the influence of preexisting muscle/limb pain and joint pain on the development of AI-induced musculoskeletal AEs. Women eligible for upfront adjuvant endocrine therapy with letrozole were included in the PreFace study, a multicenter phase IV trial. During the first treatment year, they were asked to record musculoskeletal AEs monthly by answering questions regarding pain symptoms and rating the pain intensity on a numeric rating scale from 0 (no pain) to 10 (very strong pain). Pain values were compared using nonparametric statistical tests. Overall, 1,416 patients were evaluable. The average pain value over all time points in women with preexisting muscle/limb pain was 4.3 (median 4.3); in those without preexisting pain, it was 2.0 (median 1.7). In patients without preexisting muscle/limb pain, pain levels increased relatively strongly within the first 6 months (mean increase +0.9, p < 0.00001) in comparison with those with preexisting pain (mean increase +0.3, p < 0.001), resulting in a statistically significant difference (p < 0.00001) between the two groups. The development of joint pain was similar in the two groups. Women without preexisting muscle/limb pain or joint pain have the greatest increase in pain after the start of adjuvant AI therapy. Women with preexisting pain have significantly higher pain values. The main increase in pain values takes place during the first 6 months of treatment.

PURPOSE: Evidence shows that genetic and non-genetic risk factors for breast cancer (BC) differ relative to the molecular subtype. This analysis aimed to investigate associations between epidemiological risk factors and immunohistochemical subtypes in a cohort of postmenopausal, hormone receptor-positive BC patients. METHODS: The prospective, single-arm, multicenter phase IV PreFace study (Evaluation of Predictive Factors Regarding the Effectivity of Aromatase Inhibitor Therapy) included 3529 postmenopausal patients with hormone receptor-positive early BC. Data on their epidemiological risk factors were obtained from patients' diaries and their medical histories. Data on estrogen receptor, progesterone receptor, and HER2 receptor status were obtained from pathology reports. Patients with incomplete information were excluded. Data were analyzed using conditional inference regression analysis, analysis of variance, and the chi-squared test. RESULTS: In a cohort of 3392 patients, the strongest association with the molecular subtypes of BC was found for hormone replacement therapy (HRT) before diagnosis of early BC. The analysis showed that patients who took HRT at diagnosis had luminal A-like BC more often (83.7%) than those who had never taken HRT or had stopped taking it (75.5%). Luminal B-like BC and HER2-positive BC were diagnosed more often in women who had never taken HRT or had stopped taking it (13.3% and 11.2%, respectively) than in women who were taking HRT at diagnosis of BC (8.3% and 8.0%, respectively). CONCLUSIONS: This analysis shows an association between HRT and the distribution of molecular subtypes of BC. However, no associations between other factors (e.g., age at diagnosis, body mass index, smoking status, age at menopause, number of deliveries, age at first delivery, breastfeeding history, or family history) were noted.

BACKGROUND: Conventional parameters including Ki67, hormone receptor and Her2/neu status are used for risk stratification for breast cancer. The serine protease urokinase plasminogen activator (uPA) and the plasminogen activator inhibitor type-1 (PAI-1) play an important role in tumour invasion and metastasis. Increased concentrations in tumour tissue are associated with more aggressive potential of the disease. Multigene tests provide detailed insights into tumour biology by simultaneously testing several prognostically relevant genes. With OncotypeDX®, a panel of 21 genes is tested by means of quantitative real-time polymerase chain reaction. The purpose of this pilot study was to analyse whether a combination of Ki67 and uPA/PAI-1 supplies indications of the result of the multigene test. METHODS: The results of Ki67, uPA/PAI-1 and OncotypeDX® were analysed in 25 breast carcinomas (luminal type, pT1/2, max pN1a, G2). A statistical and descriptive analysis was performed. RESULTS: With a proliferation index Ki67 of < 14%, the recurrence score (RS) from the multigene test was on average in the low risk range, with an intermediate RS usually resulting if Ki67 was > 14%. Not elevated values of uPA and PAI-1 showed a lower rate of proliferation (average 8.5%) than carcinomas with an increase of uPA and/or PAI-1 (average 13.9%); p = 0.054, Student's t-test. When Ki67 was > 14% and uPA and/or PAI-1 was raised, an intermediate RS resulted. These differences were significant when compared to cases with Ki67 < 14% with non-raised uPA/PAI-1 (p < 0.03, Student's t-test). Without taking into account the proliferative activity, an intermediate RS was also verifiable if both uPA and PAI-1 showed raised values. CONCLUSION: A combination of the values Ki67 and uPA/PAI-1 tended to depict the RS to be expected. From this it can be deduced that an appropriate analysis of this parameter combination may be undertaken before the multigene test in routine clinical practice. The increasing cost pressure makes it necessary to base the implementation of a multigene test on ancillary variables and to potentially leave it out if not required in the event of a certain constellation of results (Ki67 raised, uPA and PAI-1 raised).

During the multidisciplinary planning of postoperative therapy after breast cancer, borderline cases can arise with no clear rationale for or against adjuvant chemotherapy. In 50 hormone- receptor-positive, Her2neu-negative carcinomas of the breast with no or only minimal lymph node involvement (max. pT1a) we initiated an Oncotype DX® multigene assay in addition to the evaluation of usual parameters. In the oncology conference a vote for or against chemotherapy was taken on the basis of the conventional criteria for decision-making before the test results were available. The final recommendation was made after the multigene test. In 32 breast carcinomas (64%) a low recurrence score could be documented, while 26 (32%) showed an intermediate RS and 3 (6%) showed a high RS. In most cases the result of the test could validate the choice of therapy established using conventional criteria. In 5 cases the initial recommendation for adjuvant therapy was revised, and in 3 cases chemotherapy was secondarily recommended after evaluation of the test results. Conversely, in some cases a low or intermediate risk constellation did not argue against a recommendation for adjuvant chemotherapy. Altogether, the results of our study do not indicate that a multigene assay should be used as a routine diagnostic tool. Instead a thorough compilation and careful analysis of conventional parameters for therapeutic decision-making should take precedence, with special emphasis on histopathological and immunohistochemical results. In selected cases, however, a multigene assay can be a useful tool in the deliberation for or against a therapeutic pathway.
ABSTRACT
PURPOSE: Serodiscordant couples with a human immunodeficiency virus type 1 (HIV-1)-infected man request assisted reproductive technology (ART) in order to achieve safe conception. Most of these men are on highly active antiretroviral therapy (HAART). HIV-1 infection and the antiretroviral drugs are blamed for semen alterations. The aim of our study was to investigate the semen parameters in HIV-1-infected patients with and without HAART and to compare their sperm characteristics with those of healthy men. MATERIALS AND METHODS: A prospective study of 226 men attended the university fertility center of Mannheim between May 1996 and July 2003. The patients were divided into three groups: HIV-infected men taking antiretroviral therapy, HIV-infected patients who did not take antiretroviral therapy until now and a control group with 93 men consulting our fertility center together with their wives because of tubal sterility. Semen samples were examined with regard to ejaculate volume, sperm concentration, motility, and morphology. RESULTS: The study showed significant differences between the ejaculate of HIV-infected and non-infected men. The HIV-infected men as a whole group and the subgroup of men with HAART had a lower ejaculate volume, less slow progressive and more abnormally shaped spermatozoa compared with the control group. The HIV-infected men without an antiretroviral therapy had a significant lower ejaculate volume compared with the control group; the other parameters were not altered significantly. Differences between the subgroups with and without HAART were not significant. CONCLUSION: The spermiogram in HIV-1-infected men in comparison to a control group of healthy men is negatively altered. Especially in men with HAART, ejaculate volume as well as sperm morphology and motility changed significantly.

It is estimated that, in 2010, one in every 250 adults will be a childhood cancer survivor. This review discusses the impact of current cancer treatment on fertility potential and the assisted-reproduction innovations available today for the most common cancers in young women. As the emerging discipline of fertility preservation is steadily attracting increasing interest, developments in the near future promise to be very exciting. However, in everyday routine work, better interdisciplinary cooperation between gynecological and pediatric oncologists, surgeons, immunologists and endocrinologists is necessary so that individualized options for fertility preservation can be offered in advance of surgical procedures or cancer treatments.
ABSTRACT
Aggressive chemotherapy has improved the life expectancy for reproductive-age women with breast cancer, but it often causes infertility or premature ovarian failure due to destruction of the ovarian reserve. Many questions concerning fertility preservation in breast cancer patients remain unanswered--for example, whether fertility preservation methods interfere with chemotherapy, and whether subsequent pregnancy has negative effects on the prognosis. Fertility preservation is a critical factor in decision-making for younger breast cancer patients, however, and clinicians should address this. The present article reviews the incidence of chemotherapy-induced amenorrhea, and discusses fertility-preservation options and the prognosis for patients who become pregnant after breast cancer.

OBJECTIVE: To examine the safety and effectiveness of assisted reproduction using sperm washing for HIV-1-serodiscordant couples wishing to procreate where the male partner is infected. DESIGN AND METHODS: A retrospective multicentre study at eight centres adhering on the European network CREAThE and involving 1036 serodiscordant couples wishing to procreate. Sperm washing was used to obtain motile spermatozoa for 3390 assisted reproduction cycles (2840 intrauterine inseminations, 107 in-vitro fertilizations, 394 intra-cytoplasmic sperm injections and 49 frozen embryo transfers). An HIV test was performed in female partners at least 6 months after assisted reproduction attempt. The outcome measures recorded were number of assisted reproduction cycles, pregnancy outcome and HIV test on women post-treatment. RESULTS: A total of 580 pregnancies were obtained from 3315 cycles. Pregnancy outcome was unknown in 47 cases. The 533 pregnancies resulted in 410 deliveries and 463 live births. The result of female HIV testing after assisted reproduction was known in 967 out of 1036 woman (7.1% lost to follow-up). All tests recorded were negative. The calculated probability of contamination was equal to zero (95% confidence interval, 0-0.09%). CONCLUSION: This first multicentre retrospective study of assisted reproduction following sperm washing demonstrates the method to be effective and to significantly reduce HIV-1 transmission risk to the uninfected female partner. These results support the view that assisted reproduction with sperm washing could not be denied to serodiscordant couples in developed countries and, where possible, could perhaps be integrated into a global public health initiative against HIV in developing countries.

A local renin-angiotensin system (RAS), including specific angiotensin II receptor subtypes, is present in the rat ovary. Immunohistochemistry using a polyclonal antibody and mRNA in situ hybridization were performed on perfusion-fixed, paraffin-embedded ovaries obtained from untreated sexually mature, normally cycling rats. Immunofluorescent staining revealed an exclusive and distinct labeling of follicular granulosa cells showing a plaque-like expression pattern at the cell borders, being detectable in different stages of atretic degeneration. On adjacent sections the expression of the respective mRNA could be shown in granulosa cells of the same follicle. The AT2 receptor may be implicated in the ovarian atretic process by influencing follicular cell-cell communication.
