Long-term Follow-up and Safety of Patients after an Upfront Therapy with Letrozole for Early Breast Cancer in Routine Clinical Care - The PreFace Study.

Introduction: Adjuvant treatment of patients with early-stage breast cancer (BC) should include an aromatase inhibitor (AI). Especially patients with a high recurrence risk might benefit from an upfront therapy with an AI for a minimum of five years. Nevertheless, not much is known about the patient selection for this population in clinical practice. Therefore, this study analyzed the prognosis and patient characteristics of postmenopausal patients selected for a five-year upfront letrozole therapy. Patients and Methods: From 2009 to 2011, 3529 patients were enrolled into the adjuvant phase IV PreFace clinical trial (NCT01908556). Postmenopausal hormone receptor-positive BC patients, for whom an upfront five-year therapy with letrozole (2.5 mg/day) was indicated, were eligible. Disease-free survival (DFS), overall survival (OS) and safety in relation to patient and tumor characteristics were assessed. Results: 3297 patients started letrozole therapy. The majority of patients (n = 1639, 57%) completed the five-year treatment. 34.5% of patients continued with endocrine therapy after the mandated five-year endocrine treatment. Five-year DFS rates were 89% (95% CI: 88-90%) and five-year OS rates were 95% (95% CI: 94-96%). In subgroup analyses, DFS rates were 83%, 84% and 78% for patients with node-positive disease, G3 tumor grading, and pT3 tumors respectively. The main adverse events (any grade) were pain and hot flushes (66.8% and 18.3% of patients). Conclusions: The risk profile of postmenopausal BC patients selected for a five-year upfront letrozole therapy showed a moderate recurrence and death risk. However, in subgroups with unfavorable risk factors, prognosis warrants an improvement, which might be achieved with novel targeted therapies.

Total Pelvic Floor Lifting: A New Approach for the Anatomic Repair of Pelvic Floor Hypermobility and Vaginal Laxity in Parous Women.

Recent years have seen a steady increase in the information available regarding pelvic floor changes after childbirth. Obstetric trauma, to which all structures of the urogenital sphere are subjected, can affect different anatomical areas, including the vagina, perineum, deep pelvic floor muscles, and sphincter. Main complaints of parous women with regard to their pelvic floor are vaginal laxity, a wide introitus, and increased mobility of the uterus. Unilateral pectineal suspension is a novel method for surgical correction of the sequelae of vaginal birth-giving such as uterine hypermobility and perception of loose tissue, restoring a natural anatomy when conservative therapy has failed. Since the method is not ablative and does not interfere with anatomical structures, subsequent pregnancies and deliveries remain possible. Furthermore, there is no mesh application, adding to the safety aspects of this unique approach. The surgical technique is straightforward and can be adopted by laparoscopically trained surgeons without problems. The procedure consists of five clearly defined steps, which makes it easily reproducible. Unilateral pectineal suspension restores the pelvic floor and the vagina, with a single suture lifting the sagging structures back to their original position. If needed and according to the patient's choice, a short perineum associated with a wide introitus can be corrected in the same session by perineoplasty, resulting in a total aesthetic reconstruction of the female genital anatomy.

Retrospective analysis of apical prolapse correction by unilateral pectineal suspension: perioperative and short-term results.

INTRODUCTION AND HYPOTHESIS: We have previously published the novel method of unilateral pectineal suspension (UPS) for apical prolapse correction. UPS provides mesh-free midline uterus suspension using a single non-absorbable suture to attach the anterior cervix to the lateral part of the iliopectineal ligament. The purpose of this retrospective cohort study was to analyze the short-term efficacy, perioperative complication rate, and overall patient acceptance of the new UPS surgical concept. METHODS: Forty-seven patients with POP-Q stage 2-4 who underwent robotic UPS between January 1, 2020 and December 31, 2021 were included in the study. Patient data were taken retrospectively from the patient files. Treatment success was the primary endpoint, measured both objectively using a defined composite endpoint and subjectively according to patients' acceptance 3-6 months after surgery during a follow-up examination. Secondary outcome measures included complications and conversions, and effect of additional procedures on operative time. RESULTS: Treatment success as measured by the defined composite endpoint was 93.6% for the entire cohort. No complications or conversions occurred. Mean operation time for isolated UPS was 46.5 min (n = 33 patients). UPS can be easily combined with additional surgical procedures for repair of remaining pelvic floor defects, incontinence surgery or other indications. Additional procedures performed had a significant influence on operation time (p < 0.0005, n = 14). CONCLUSIONS: UPS shows highly favorable results when looking at an unselected cohort of patients in need of primary POP surgery with respect to established quality parameters of POP repair.

H2S in Critical Illness-A New Horizon for Sodium Thiosulfate?

Ever since the discovery of endogenous H2S and the identification of its cytoprotective properties, efforts have been made to develop strategies to use H2S as a therapeutic agent. The ability of H2S to regulate vascular tone, inflammation, oxidative stress, and apoptosis might be particularly useful in the therapeutic management of critical illness. However, neither the inhalation of gaseous H2S, nor the administration of inorganic H2S-releasing salts or slow-releasing H2S-donors are feasible for clinical use. Na2S2O3 is a clinically approved compound with a good safety profile and is able to release H2S, in particular under hypoxic conditions. Pre-clinical studies show promise for Na2S2O3 in the acute management of critical illness. A current clinical trial is investigating the therapeutic potential for Na2S2O3 in myocardial infarct. Pre-eclampsia and COVID-19 pneumonia might be relevant targets for future clinical trials.

Human Placental Tissue Contains A Placental Lactogen-Derived Vasoinhibin.

Hormonal factors affecting the vascular adaptions of the uteroplacental unit in noncomplicated and complicated pregnancies are of interest. Here, 4 human placentas from women with and without preeclampsia (PE) were investigated for the presence of placental lactogen (PL)-derived, antiangiogenic vasoinhibin. Western blotting and mass spectrometry of placental tissue revealed the presence of a 9-kDa PL-derived vasoinhibin, the normal 22-kDa full-length PL, and a 28-kDa immunoreactive protein of undetermined nature. The sequence of the 9-kDa vasoinhibin includes the antiangiogenic determinant of vasoinhibin and could constitute a relevant factor in normal pregnancy and PE.

Robotic mesh-supported pectopexy for pelvic organ prolapse: expanding the options of pelvic floor repair.

Pelvic organ prolapse affects 30-50% of the female population. For definitive treatment surgery is unavoidable. Sacrocolpopexy has been the gold standard for anatomical correction of pelvic organ prolapse since the 1990s. Recently, pectopexy has been introduced as a new surgical procedure to correct apical prolapse. We have translated the laparoscopic pectopexy into a robotic procedure. The charts of the first 30 consecutive patients who underwent robotic pectopexy at the department for robotic and pelvic floor surgery were reviewed. All patients were analyzed for estimated blood loss, operation time, as well as complications. Treatment success was evaluated after 3-6 months using a composite endpoint including anatomical and subjective components. Of the 30 patients analyzed, 18 underwent hysteropectopexy (n = 18), 6 patients underwent vaginopectopexy and 6 patients underwent cervicopectopexy. Additional procedures were performed in 14 patients, and this influenced operation time and intraoperative blood loss. No intraoperative complications were noted and no conversions were necessary. Treatment success according to the primary composite endpoint was achieved in 30 (100%) patients. Furthermore, neither de novo urgency nor obstructive bowel symptoms were noted in any of the patients treated with robotic pectopexy. Similar to SCP, pectopexy is designed for prolapse repair. The robotic technique for pectopexy capitalizes on the advantages of robotic surgery as compared to conventional laparoscopy since it allows for anatomical preparation and simplification of applying sutures and mesh material, reducing operating time and minimizing surgical trauma. The technique is safe, and anatomical outcomes are excellent.

Survival benefit of tamoxifen in male breast cancer: prospective cohort analysis.

BACKGROUND: Due to the lack of prospective data, current treatment of male breast cancer (MBC) is based on information obtained from retrospective analysis or by extrapolation from studies on female patients. In this prospectively enrolled cohort study, we retrospectively examined the survival effect of tamoxifen in MBC patients. METHODS: In this prospectively enrolled cohort study, 448 patients with MBC were treated between May 2009 and June 2018. The primary endpoint was disease-free survival (DFS). RESULTS: Between May 2009 and June 2018, 448 men with breast cancer were identified, with a median age at diagnosis of 69 years (range 27-96 years). The median follow-up was 39 months (range 3-89 months). Most tumours were larger than 20 mm; invasive ductal carcinoma was of no special histological type and with an intermediate grade of differentiation. Almost half of the men were diagnosed with positive axillary lymph nodes (43.5%). Hormone receptor (HR) positivity was observed in 98.4% of the patients. Notably, DFS among men who did not receive tamoxifen was significantly reduced as compared with those who underwent tamoxifen therapy (P = 0.002). The recurrence rate and mortality in the group of patients without and with tamoxifen treatment were 18.2% and 11.2%, respectively. The most common localisation of metastases was the bone. After adjustment for prognostic factors, we found that tamoxifen was found to reduce the recurrence rate by 68% (hazard ratio HR = 0.32; 95% confidence interval, CI: 0.14-0.74). CONCLUSIONS: Tamoxifen treatment was associated with improved DFS for MBC patients. CLINICAL TRIAL REGISTRATION: DRKS00009536.

Influence of patient and tumor characteristics on therapy persistence with letrozole in postmenopausal women with advanced breast cancer: results of the prospective observational EvAluate-TM study.

BACKGROUND: Treatment of postmenopausal, hormone receptor-positive metastatic breast cancer (MBC) patients varies despite clear therapy guidelines, favoring endocrine treatment (ET). Aim of this study was to analyze persistence of palliative aromatase inhibitor (AI) monotherapy in MBC patients. METHODS: EvAluate-TM is a prospective, multicenter, noninterventional study to evaluate treatment with letrozole in postmenopausal women with hormone receptor-positive breast cancer. To assess therapy persistence, defined as the time from therapy start to the end of the therapy (TTEOT), two pre-specified study visits took place after 6 and 12 months. Competing risk survival analyses were performed to identify patient and tumor characteristics that predict TTEOT. RESULTS: Out of 200 patients, 66 patients terminated treatment prematurely, 26 (13%) of them due to causes other than disease progression. Persistence rate for reasons other than progression at 12 months was 77.7%. Persistence was lower in patients who reported any adverse event (AE) in the first 30 days of ET (89.5% with no AE and 56% with AE). Furthermore, patients had a lower persistence if they reported compliance problems in the past before letrozole treatment. CONCLUSIONS: Despite suffering from a life-threatening disease, AEs of an AI will result in a relevant number of treatment terminations that are not related to progression. Some subgroups of patients have very low persistence rates. Especially with regard to novel endocrine combination therapies, these data imply that some groups of patients will need special attention to guide them through the therapy process. TRIAL REGISTRATION: Clinical Trials Number: CFEM345DDE19.

Preexisting musculoskeletal burden and its development under letrozole treatment in early breast cancer patients.

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.

Association between breast cancer risk factors and molecular type in postmenopausal patients with hormone receptor-positive early breast cancer.

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.

Oncotype DX® in breast cancer patients: clinical experience, outcome and follow-up-a case-control study.

PURPOSE: Breast cancer is the leading cause of death from cancer in women and the most common cancer in the world [1]. To date, many patients with estrogen-receptor-positive (ER+) breast cancer are overtreated with chemotherapy when the rationale for adjuvant chemotherapy is based on clinicopathologic parameters. Different studies were able to demonstrate that a 21-gene expression assay (Oncotype DX® Genomic Health, Redwood City, CA) can predict the benefit from adjuvant chemotherapy in ER+ breast cancers [2, 3] and provide additional prognostic information independent of clinicopathological features [4]. RESULTS: Data from all patients with ER+ Her2neu- breast cancer undergoing Oncotype DX® testing between 2011 and 2014 at a tertiary referral center in Germany were analyzed. Oncotype DX® was performed in 69 cases, in 2 cases data were missing and in 3 cases Oncotype DX® could not be performed by the company. The results showed a low risk in 39 cases, an intermediate risk in 22 cases and a high risk in 3 cases. Based on Oncotype results, treatment recommendations were changed in 39 of 64 patients (61%). Before Oncotype DX® testing, chemotherapy was recommended in 67 patients, afterwards only in 25 patients. Data from 44 of 67 patients were matched to controls for stage, tumor grade, menopausal and hormone receptor status. Within a mean observation time of 19.7 months, cancer recurrence was observed in two patients. CONCLUSIONS: Oncotype DX® testing can be recommended for risk-tailored chemotherapy. Results should be validated in larger prospective studies.

Gynecologic oncologists' attitudes and practices relating to integrative medicine: results of a nationwide AGO survey.

PURPOSE: The growing popularity and acceptance of integrative medicine is evident both among patients and among the oncologists treating them. As little data are available regarding health-care professionals' knowledge, attitudes, and practices relating to the topic, a nationwide online survey was designed. METHODS: Over a period of 11 weeks (from July 15 to September 30, 2014) a self-administered, 17-item online survey was sent to all 676 members of the Research Group on Gynecological Oncology (Arbeitsgemeinschaft Gynäkologische Onkologie) in the German Cancer Society. The questionnaire items addressed the use of integrative therapy methods, fields of indications for them, advice services provided, level of specific qualifications, and other topics. RESULTS: Of the 104 respondents (15.4%) using integrative medicine, 93% reported that integrative therapy was offered to breast cancer patients. The second most frequent type of tumor in connection with which integrative therapy methods were recommended was ovarian cancer, at 80% of the participants using integrative medicine. Exercise, nutritional therapy, dietary supplements, herbal medicines, and acupuncture were the methods the patients were most commonly advised to use. CONCLUSION: There is considerable interest in integrative medicine among gynecological oncologists, but integrative therapy approaches are at present poorly implemented in routine clinical work. Furthermore there is a lack of specific training. Whether future efforts should focus on extending counseling services on integrative medicine approaches in gynecologic oncology or not, have to be discussed. Evidence-based training on integrative medicine should be implemented in order to safely guide patients in their wish to do something by themselves.

Interest in Integrative Medicine Among Postmenopausal Hormone Receptor-Positive Breast Cancer Patients in the EvAluate-TM Study.

BACKGROUND: Breast cancer patients often use complementary and alternative medicine, but few prospectively collected data on the topic are available specifically for postmenopausal breast cancer patients. A large prospective study was therefore conducted within a noninterventional study in order to identify the characteristics of patients interested in integrative medicine. METHODS: The EvAluate-TM study is a prospective, multicenter noninterventional study in which treatment with the aromatase inhibitor letrozole was evaluated in postmenopausal women with hormone receptor-positive primary breast cancer. Between 2008 and 2009, 5045 postmenopausal patients were enrolled at 339 certified breast centers in Germany. As part of the data collection process, patients were asked at the baseline about their interest in and information needs relating to integrative medicine. RESULTS: Of the 5045 patients recruited, 3411 responded to the questionnaire on integrative medicine and took part in the analysis, 1583 patients expressed an interest in integrative medicine, and 1828 patients declared no interest. Relevant predictors of interest in integrative medicine were age, body mass index, tumor size, previous chemotherapy, and use of concomitant medications for other medical conditions. Interest in integrative medicine declined highly significantly ( P < .001) with age (<50 years, 74.1%; 50-60 years, 54.1%; >65 years, 38.0%). Patients in favor of integrative medicine were significantly less satisfied with the information received about individual treatments and antihormonal therapy. Patients with interest in integrative medicine were more often interested in rehabilitation and fitness, nutritional counseling, and additional support from self-help organizations. These women were mostly interested in receiving information about their disease and integrative medicine from a physician, rather than from other sources. CONCLUSIONS: This study shows that a considerable proportion of postmenopausal breast cancer patients are interested in integrative medicine. Information about integrative medicine should therefore be provided as part of patient care for this group. It was found that receiving concomitant medication for other medical conditions is one of the main predictors for women not being interested in integrative medicine. This group of patients may need special attention and individualized information about integrative medicine. Additionally, most patients were interested in obtaining the relevant information from their doctor.

Factors Influencing Decision-Making for or against Adjuvant and Neoadjuvant Chemotherapy in Postmenopausal Hormone Receptor-Positive Breast Cancer Patients in the EvAluate-TM Study.

BACKGROUND: Decision-making for or against neoadjuvant or adjuvant chemotherapy in postmenopausal patients with hormone receptor-positive breast cancer does not follow any clear guidelines, and some patients may unnecessarily undergo chemotherapy and be exposed to the associated toxicity. The aim of this study was to identify the patient population for whom this issue may bear relevance. METHODS: Patients being treated with letrozole in the prospective multicenter noninterventional EvAluate-TM study were recruited. The percentage of patients receiving chemotherapy and factors associated with chemotherapy administration were identified. RESULTS: In all, 3,924 (37.4%) patients received chemotherapy before treatment with letrozole. Of these, 293 (20%) underwent neoadjuvant therapy. Younger age was predictive for both adjuvant and neoadjuvant therapy. Overall, decisions in favor of administering chemotherapy are more likely to be made in patients with a higher body mass index (BMI), and neoadjuvant chemotherapy is administered at a higher rate in women with a lower BMI. Concomitant medication influenced the overall decision-making regarding chemotherapy, irrespective of whether it was given on a neoadjuvant or adjuvant basis. CONCLUSION: There is an ongoing debate as to whether all of the many patients who receive chemotherapy actually benefit from it. Neoadjuvant chemotherapy is frequently administered in this patient population, and this should encourage further research to resolve current clinical and research issues.

Quality assured health care in certified breast centers and improvement of the prognosis of breast cancer patients.

BACKGROUND: Increasing effort has been put in the implementation and certification of breast centers in order to establish standardized, quality assured health care for breast cancer patients. The aim of this analysis was to investigate whether patients treated in certified breast centers (CBC) have a favorable prognosis as compared to patients treated outside of certified breast treatment units. PATIENTS AND METHODS: The data of 3,940 patients with invasive nonmetastatic breast cancer were analyzed with regard to differences in patient and tumor characteristics and crude overall survival according to diagnosis in or outside CBC in Middle Franconia, Germany. Patient, tumor, and follow-up data were obtained from the clinical cancer registry. RESULTS: Patients in CBC were younger, and had lower disease stages and lower grading. Independent of the effects of these variables on overall survival, being treated at a CBC added to the prediction of overall survival. Patients treated at a CBC had a hazard ratio of 0.70 (95% confidence interval 0.52-0.93) in the adjusted Cox model. CONCLUSIONS: Independent from common prognostic factors, diagnosis and treatment of breast cancer at a CBC improves the prognosis of patients. It can be hypothesized that this effect is mediated through quality assured health care provided by the certification process.

Autoantigens in ovarian autoimmunity associated with unexplained infertility and premature ovarian failure.

OBJECTIVE: To identify ovarian autoantigens associated with ovarian autoantibodies. DESIGN: Hypothesis-generating prospective study. SETTING: Urban infertility referral centers and academic research institution. PATIENT(S): Seventy-four patients with infertility, 19 patients with premature ovarian failure (POF), and 16 healthy control women. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Identification of autoantigens. RESULT(S): To identify major antigens for ovarian autoimmunity, sera from 74 women with unexplained infertility were screened for ovarian autoantibodies (AOAs) by immunoassay and one-dimensional Western blot. The majority of sera had immunoreactions at 50-56 kDa. Six representative positive infertility sera were used to identify antigens between 40 and 60 kD by two-dimensional Western blot and mass spectrometry. Antigens included aldehyde (retinal) dehydrogenases (ALDH1A1, ALDH1A2, and ALDH7A1), protein disulfide isomerase A3, vimentin, α-enolase, phosphoglycerate dehydrogenase, and selenium-binding protein 1 (SBP1). Sixty percent (24 out of 40) of infertility and POF sera were positive for recombinant ALDH1A1, SBP1, or enolase; 80.7% (21 out of 26) of AOA-positive sera had antibodies to one or more of the three antigens, and only 7% (1 out of 14) of AOA-negative sera had antibodies to recombinant proteins. CONCLUSION(S): ALDH1A1 and SBP1 are unique to ovarian autoimmunity associated with infertility and POF, and may provide the basis for specific tests to identify patients with ovarian autoimmunity.

Long-term efficacy and safety of a monophasic combined oral contraceptive containing 0.02 mg ethinylestradiol and 2 mg chlormadinone acetate administered in a 24/4-day regimen.

OBJECTIVE: This study was conducted to assess the long-term efficacy and safety of a low-dose monophasic combined oral contraceptive (COC) containing 0.02 mg ethinylestradiol (EE) and 2 mg chlormadinone acetate (CMA) in a novel regimen administered daily for 24 days followed by a 4-day placebo interval. STUDY DESIGN: In this multicenter, uncontrolled, Phase III trial, 1665 subjects took the COC 0.02 mg EE/2 mg CMA for up to 21 cycles. The overall Pearl Index was the primary end point; cycle control, safety, effect on acne and seborrhea, and changes in body weight and libido were secondary end points. RESULTS: Contraceptive efficacy was analyzed for 1653 subjects completing 21,495 cycles. Six pregnancies occurred during trial duration with one attributable to method failure. The overall Pearl Index for the first year of use was 0.33 (95% confidence interval, 0.09-0.85). The mean number of bleeding/spotting days during six 90-day reference periods (RPs) decreased from 17.0 (RP 1) to 11.7 (RP 6), and the number of bleeding episodes per RP decreased from 3.8 (RP 1) to 2.7 (RP 6). Among subjects who presented with acne at the baseline visit, a decrease of papules/pustules and comedones was observed during the course of the trial. The most common "at least possibly related" adverse events were headache, breast discomfort and nausea. The tolerability and well-being was reported as being excellent or good in the majority of trial subjects (84.6% and 80.2%, respectively). CONCLUSIONS: The low-dose COC 0.02 mg EE/2 mg CMA administered daily for 24 days followed by a 4-day placebo interval provides high contraceptive efficacy combined with an adequate cycle control and safety profile, beneficial effects on acne, and is well tolerated.
