Since 1990 the WHO Global Tuberculosis Programme (GTB) has promoted the revision of national tuberculosis programmes to strengthen the focus on directly observed treatment, short-course (DOTS) and close monitoring of treatment outcomes. GTB has encouraged in-depth evaluation of activities through a comprehensive programme review. Over the period 1990-95, WHO supported 12 such programme reviews The criteria for selection were as follows: large population (Bangladesh, Brazil, China, Ethiopia, India; Indonesia, Mexico, and Thailand); good prospects of developing a model programme for a region (Nepal, Zimbabwe); or at advanced stage of implementation of a model programme for a region (Guinea Peru). The estimated combined incidence of smear-positive pulmonary tuberculosis was 82 per 100 000 population, about 43% of the global incidence. The prevalence of infection with human immunodeficiency virus (HIV) was variable, being very high in Ethiopia and Zimbabwe but negligible in Bangladesh, China, Nepal and Peru. The programme reviews were conducted by teams of 15-35 experts representing a wide range of national and external institutions. After a 2-3-month preparatory period, the conduct of the review usually lasted 2-3 weeks, including a first phase of meetings with authorities and review of documents, a second phase for field visits, and a third phase of discussion of findings and recommendations. The main lessons learned from the programme reviews were as follows: programme review is a useful tool to secure government commitment, reorient the tuberculosis control policies and replan the activities on solid grounds the involvement of pubic health and academic institutions cooperating agencies and nongovernmental organizations secured a broad support to the new policies; programme success is linked to a centralized direction which supports a decentralized implementation through the primary health care services; monitoring and evaluation of case management functions well if it is based on the right classification of cases and quarterly reports on cohorts of patients, a comprehensive programme review Should include teaching about tuberculosis in medical, nursing, and laboratory workers' schools; good quality diagnosis and treatment are the essential requirements for expanding a programme beyond the pilot testing, and control targets cannot be achieved if private and social security patients are left outside the programme scope. The methodology of comprehensive programme review should be recommended to all countries which require programme reorientation; it is also appropriate for carrying out evaluations at 4-5-year intervals in countries that are implementing the correct tuberculosis control policies., Introduction Since 1990 the WHO Global Tuberculosis Programme (GTB) has promoted the revision of national tuberculosis programmes to strengthen focus on the following: passive case finding; directly observed treatment, short-course [...]

Deaths due to tuberculosis have decreased uniformly in all countries in Western Europe, and most have occurred among those aged [is greater than or equal to] 65 years. In recent years, tuberculosis case notifications have continued to decline in Belgium, Finland, France, Germany, and Spain, and have levelled off in Sweden and the United Kingdom; increases have, however, been recorded in Austria, Denmark, Ireland, Italy, Netherlands, Norway, and Switzerland. In Denmark, Netherlands, Norway, Sweden, and Switzerland an increasing number of cases of tuberculosis among foreign-born residents has resulted in a change from the expected downward trend. Human immunodeficiency virus (HIV) infection appears to contribute only marginally to the overall tuberculosis morbidity; however, it appears to be important in Paris and its surrounding areas, and tuberculosis is very common among HIV-infected persons in Italy and Spain. Despite these recent changes in the incidence of tuberculosis, there is currently no evidence of its increased transmission among the youngest age groups of the indigenous populations. Properly designed disease surveillance systems are critical for monitoring the tuberculosis trends so that each country can identify its own high-risk groups and target interventions to prevent, diagnose, and treat the disease. Tuberculosis remains a global disease and because of increasing human migrations, its elimination in Western Europe cannot be envisaged without concomitant improvements in its control in high-incidence, resource-poor countries., Introduction In several industrialized countries the regular decline in tuberculosis notifications, as expected from years of observation, appears to have become disturbed. The phenomenon was first reported in the USA [...]

Chyloperitoneum is not rare and is often associated with other chylous disorders particularly in more complex clinical conditions. An accurate diagnostic study is indispensable to plan the correct therapeutic approach, and we examined the long-term outcomes of our experience in the management of primary and secondary chyloperitoneum in fifty-eight patients (50 adults and 8 children; 34 primary and 24 secondary forms). Diagnostic assessment consisted of paracentesis, whole body lymphoscintigraphy, lymphangio-MR, and lymphangio-CT (LAG-CT). The management of chyloperitoneum consisted initially of non-operative procedures (MCT diet, TPN, octreotide). Surgical treatment was performed in patients not responsive to conservative methods and involved different options using surgical and microsurgical approaches. Microsurgical techniques included chylousvenous shunts connecting chyliferous vessels and mesenteric veins. Fibrin glue or platelet gel injection at the site of the chylous leakage was also used to treat one case of refractory secondary chyloperitoneum. Patients were followed clinically and instrumentally (echography and labs tests) for 6 months to over 5 years. We found that LAG-CT was the primary diagnostic modality to provide precise topographic information concerning the site, cause, and extension of chylous pathology, all of which allowed proper planning of therapeutic procedures. Thirty-four patients did not have a relapse of the chyloperitoneum and 22 patients had a persistence of a small quantity of ascites with no protein imbalance. We observed early relapse of chylous ascites in 2 cases that required a peritoneal-jugular shunt leading to good outcomes. An accurate diagnostic study (above all LAG-CT) and a microsurgical approach proved to represent an effective management of chyloperitoneum refractory to non-operative treatment.

The effects of inhaled MgSO4on histamine bronchoprovocation test (BPT) were studied in nine asthmatics in clinical remission (FEV1> 80% of predicted). Patients performed histamine BPT on 2 separate days, one day after saline and the other after MgSO4 inhalation, in a randomized double-blind design. Spirometry and flow/volume curve were recorded on each test day before and 5 min after NaCl or MgSO4. No significant difference was observed in lung function measurements 2 days before and after either NaCl or MgSO4. The dose of histamine which produced a 20% decrease in control FEV1 (PD20FEV1]) was significantly increased by aerosolized MgSO4 (from 0.177 ± 0.036 mg after NaCl to 0.350 ± 0.085 after MgSO4, P < 0.05. After MgSO4 the dose-steps of histamine concentration increased two-fold in two subjects and one-fold in five. [ABSTRACT FROM AUTHOR]

There is considerable exigency to take all necessary steps to cure tuberculosis cases and prevent further emergence of drug-resistant tuberculosis. The most important of these steps is to ensure that the treatment, particularly of sputum smear-positive cases, is adequate and that patients adhere to their treatment by supervised, direct observation of drug-taking according to the standardized regimens. Use of fixed-dose combinations (FDCs) of tablets against tuberculosis is now being recommended by WHO and the International Union Against Tuberculosis and Lung Disease (IUATLD) as an additional step to ensuring proper treatment. FDCs simplify the prescription of drugs and the management of drug supply, and may also limit the risk of drug-resistant tuberculosis arising as a result of inappropriate drug selection and monotherapy. Only FDCs of proven quality and proven rifampicin bioavailability should be purchased and used. In most situations, blood levels of the drugs are inadequate because of poor drug quality rather than poor absorption. This is true irrespective of the human immunodeficiency virus (HIV) infection status of the tuberculosis patients (other than those with overt acquired immunodeficiency syndrome, with CD4 counts

Introduction: Anticancer treatments have significantly contributed to increasing cure rates of breast cancer in the last years; however, they can also lead to short- and long-term side effects, including gonadotoxicity, and compromised fertility in young women. Oncofertility is a crucial issue for young patients who have not yet completed their family planning at the time of cancer diagnosis., Areas Covered: This review aims to cover all the latest available evidence in the field of oncofertility, including the gonadotoxicity of currently adopted anticancer therapies in the curative breast cancer setting, the available strategies for fertility preservation and the feasibility of achieving a pregnancy following anticancer treatment completion., Expert Opinion: Over the past years, a significant progress has been made in oncofertility care for young women with breast cancer. In the context of the currently available evidence, every young woman with newly diagnosed breast cancer should receive a proper and complete oncofertility counseling before starting any anticancer treatment to increase her chances of future pregnancies.

The drug's activity at the target tissue could help to define the minimal effective dose to promote cancer preventive therapy. Here we present exemestane and sex hormone concentrations within breast tissue from a pre-surgical study of alternative exemestane schedules. Postmenopausal women candidate for breast surgery for estrogen receptor-positive breast cancer were randomized to exemestane 25 mg once daily (QD), 25 mg three times/week (TIW), or 25 mg per/week (QW) for 4-6 weeks before surgery. Drug and sex hormones were analyzed from homogenized frozen tissue using a QTRAP 6500+ LC-MS/MS System. Tissue drug concentrations were detectable only in the QD arm with higher concentrations in non-malignant tissue. Estradiol was nearly suppressed in all groups in the non-malignant tissue (QD vs TIW p = .364 and QD vs QW p = .693). In contrast, a dose-response trend was observed in cancer tissue. Based on estradiol suppression in non-malignant tissue, lower exemestane schedules should be explored for breast cancer preventive therapy., (© The Author(s) 2024. Published by Oxford University Press.)

In a 3-arm presurgical trial, four-six weeks exemestane 25 mg three times/week (TIW) was non-inferior to 25 mg/day (QD) in suppressing circulating estradiol in postmenopausal women with ER-positive breast cancer. Since obesity may decrease exemestane efficacy, we analyzed changes in sex steroids, adipokines, Ki-67, and drug levels in relation to obesity. Postmenopausal women with early-stage ER-positive breast cancer were randomized to either exemestane 25 mg QD (n = 57), 25 mg TIW (n = 57), or 25 mg/week (QW, n = 62) for 4-6 weeks before breast surgery. Serum and tissue pre- and post-treatment biomarkers were stratified by body mass index (BMI)< or ≥30 kg/m 2 . Post-treatment median exemestane and 17-OH exemestane levels were 5-6 times higher in the QD arm compared to the TIW arm. For obese women, TIW maintained comparable reductions to QD in systemic estradiol levels, although the reduction in estrone was less with the TIW regimen. There was less suppression of SHBG with the TIW versus the QD dose schedule in obese women which should result in less systemic bioavailable estrogens. Metabolically, the effect of the TIW regimen was similar to the QD regimen for obese women in terms of leptin suppression and increase in the adiponectin-leptin ratio. Reduction in tissue Ki-67 was less for obese women on the TIW regimen than QD, although changes were similar for non-obese women. Our findings suggest that TIW exemestane should be explored further for primary cancer prevention in both normal weight and obese cohorts., (© 2024. The Author(s).)

Background: In clinically node-positive (cN+) breast cancer (BC) patients who become clinically node-negative (cN0) following neoadjuvant chemotherapy (NACT), sentinel lymph node biopsy (SLNB) after lymphatic mapping with lymphoscintigraphy is not widely accepted; therefore, it has become a topic of international debate., Objective: Our literature review aims to evaluate the current use of this surgical practice in a clinical setting and focuses on several studies published in the last six years which have contributed to the assessment of the feasibility and accuracy of this practice, highlighting its importance and oncological safety. We have considered the advantages and disadvantages of this technique compared to other suggested methods and strategies. We also evaluated the role of local irradiation therapy after SLNB and state-of-the-art SLN mapping in patients subjected to NACT., Methods: A comprehensive search of PubMed and Cochrane was conducted. All studies published in English from 2018 to August 2023 were evaluated., Results: Breast units are moving towards a de-escalation of axillary surgery, even in the NACT setting. The effects of these procedures on local irradiation are not very clear. Several studies have evaluated the oncological outcome of SLNB procedures. However, none of the alternative techniques proposed to lower the false negative rate (FNR) of SLNB are significant in terms of prognosis., Conclusions: Based on these results, we can state that lymphatic mapping with SLNB in cN+ BC patients who become clinically node-negative (ycN0) following NACT is a safe procedure, with a good prognosis and low axillary failure rates.

Introduction: Breast cancer is the most commonly diagnosed malignancy during pregnancy. Breast cancer during pregnancy is a challenging clinical condition requiring proper and timely multidisciplinary management., Areas Covered: This review focuses on the management of breast cancer during pregnancy with a focus about the current state-of-the-art on the feasibility and safety of pharmacotherapy approaches in this setting., Expert Opinion: Multidisciplinary care is key for a proper diagnostic-therapeutic management of breast cancer during pregnancy. Engaging patients and their caregivers in the decision-making process is essential and psychological support should be provided. The treatment of patients with breast cancer during pregnancy should follow the same recommendations as those for breast cancer in young women outside pregnancy but taking into account the gestational age at the time of treatment.Anthracycline-, cyclophosphamide-, and taxane-based regimens can be safely administered during the second and third trimesters with standard protocols, preferring weekly regimens whenever possible. Endocrine therapy, immune checkpoint inhibitors, and targeted agents are contraindicated throughout pregnancy, also due to the very limited data available to guide their administration in this setting. During treatment, careful fetal growth monitoring is mandatory, and even after delivery proper health monitoring for the children exposed in utero to chemotherapy should be continued.

Importance: Successful therapeutic cancer prevention requires definition of the minimal effective dose. Aromatase inhibitors decrease breast cancer incidence in high-risk women, but use in prevention and compliance in adjuvant settings are hampered by adverse events., Objective: To compare the noninferiority percentage change of estradiol in postmenopausal women with estrogen receptor-positive breast cancer given exemestane, 25 mg, 3 times weekly or once weekly vs a standard daily dose with a noninferiority margin of -6%., Design, Setting, and Participants: This multicenter, presurgical, double-blind phase 2b randomized clinical trial evaluated 2 alternative dosing schedules of exemestane. Postmenopausal women with estrogen receptor-positive breast cancer who were candidates for breast surgery were screened from February 1, 2017, to August 31, 2019. Blood samples were collected at baseline and final visit; tissue biomarker changes were assessed from diagnostic biopsy and surgical specimen. Biomarkers were measured in different laboratories between April 2020 and December 2021., Interventions: Exemestane, 25 mg, once daily, 3 times weekly, or once weekly for 4 to 6 weeks before surgery., Main Outcomes and Measures: Serum estradiol concentrations were measured by solid-phase extraction followed by liquid chromatography-tandem mass spectrometry detection. Toxic effects were evaluated using the National Cancer Institute terminology criteria, and Ki-67 was assessed by immunohistochemistry., Results: A total of 180 women were randomized into 1 of the 3 arms; median (IQR) age was 66 (60-71) years, 63 (60-69) years, and 65 (61-70) years in the once-daily, 3-times-weekly, and once-weekly arms, respectively. In the intention-to-treat population (n = 171), the least square mean percentage change of serum estradiol was -89%, -85%, and -60% for exemestane once daily (n = 55), 3 times weekly (n = 56), and once weekly (n = 60), respectively. The difference in estradiol percentage change between the once-daily and 3-times-weekly arms was -3.6% (P for noninferiority = .37), whereas in compliant participants (n = 153), it was 2.0% (97.5% lower confidence limit, -5.6%; P for noninferiority = .02). Among secondary end points, Ki-67 and progesterone receptor were reduced in all arms, with median absolute percentage changes of -7.5%, -5.0%, and -4.0% for Ki-67 in the once-daily, 3-times-weekly, and once-weekly arms, respectively (once daily vs 3 times weekly, P = .31; once daily vs once weekly, P = .06), and -17.0%, -9.0%, and -7.0% for progesterone receptor, respectively. Sex hormone-binding globulin and high-density lipoprotein cholesterol had a better profile among participants in the 3-times-weekly arm compared with once-daily arm. Adverse events were similar in all arms., Conclusions and Relevance: In this randomized clinical trial, exemestane, 25 mg, given 3 times weekly in compliant patients was noninferior to the once-daily dosage in decreasing serum estradiol. This new schedule should be further studied in prevention studies and in women who do not tolerate the daily dose in the adjuvant setting., Trial Registration: ClinicalTrials.gov Identifier: NCT02598557; EudraCT: 2015-005063-16.

In patients with early breast cancer, the combination of different systemic treatment strategies, including chemotherapy, endocrine therapy, targeted therapy, and more recently also immunotherapy has demonstrated to significantly improve their survival outcomes. However, this gain is often obtained at the cost of higher toxicity calling for the need of increased attention toward survivorship-related issues, including fertility preservation in young women. According to available guidelines, health care providers should offer oncofertility counseling to all patients with cancer diagnosed at reproductive age. Counselling should focus on the risk of gonadotoxicity of anticancer treatments and on the access to fertility preservation techniques. However, several surveys have demonstrated suboptimal implementation of these recommendations. This review aims at summarizing the available evidence on oncofertility to guide health care providers involved in the management of young women with breast cancer. Available and effective options for fertility preservation include oocyte/embryo cryopreservation or ovarian tissue cryopreservation. Patient, disease, and treatment characteristics should be carefully considered when offering these strategies. Ovarian function preservation with gonadotrophin-releasing hormone agonists during chemotherapy should be discussed and offered to every premenopausal woman concerned about developing premature ovarian insufficiency and independently of her wish to preserve fertility. Current available data confirm that pregnancy occurring after proper treatment for breast cancer is safe, both in terms of long-term clinical outcomes and for the babies. Fertility preservation and pregnancy desire should be pivotal components of the multimodal management of breast cancer in young women, and require a multidisciplinary approach based on close collaborations between oncologists and fertility specialists., Competing Interests: Disclosure Matteo Lambertini reports advisory role for Roche, Lilly, Novartis, Astrazeneca, Pfizer, Seagen, Gilead, MSD and Exact Sciences and speaker honoraria from Roche, Lilly, Novartis, Pfizer, Sandoz, Libbs, and Takeda, and Travel Grants from Gilead outside the submitted work.

Background: Breast cancer is traditionally classified into three clinical subtypes based on hormone receptor and HER2 status (i.e., luminal-like, HER2-positive, and triple negative). Each subtype has distinct clinical-pathological and molecular characteristics and requires tailored treatments. Recent research efforts have been focusing on a new classification, identifying the so-called "HER2-low" category, including tumors characterized by a low level of HER2 expression (immunohistochemistry score 1+ or 2+ without in situ hybridization amplification). Emerging evidence shows that patients with HER2-low tumors can derive benefit from selected anti-HER2 therapies. This represents a major advancement in the field of breast oncology, where a broader proportion of patients with breast cancer can ultimately benefit from new effective targeted treatment strategies., Summary: The antibody-drug conjugate trastuzumab deruxtecan has proven impressive efficacy in patients with HER2-low breast cancer, and several other drugs are currently under investigation in this subset of patients. Additional investigation is needed to address open issues that exist in this field, including appropriate pathological assessment of HER2-low status, clarification of its prognostic implications, and global access to newly approved drugs., Key Message: Our review aims to summarize the available evidence regarding HER2-low breast cancer, illustrating the current challenges that are being addressed and the future perspectives in this exciting new field., Competing Interests: Dr. Molinelli received honoraria from Novartis and Lilly outside the submitted work.

Background and Aim: In vulvar cancer, the standard treatment is radical local excision, with immediate reconstruction. Reconstruction aims to restore anatomy and function of the external female genitalia, facilitating preservation of normal body image, sexual function, and micturition and defecation functions., Methods: The purpose of this paper is to describe the principles of perforator flaps for vulvar reconstruction., Results: Basic concepts, indications and operative technique are discussed and detailed., Conclusions: In vulvar reconstruction, the use of perforator flaps is a superior surgical technique when compared to the use of conventional flaps.

Abstract: Survivorship has become a crucial component in breast cancer care. For women who have not completed their family planning, conceiving at the end of anticancer treatments should not be discouraged but might be challenging. Oncofertility counseling should be offered at the time of diagnosis to all patients, in order to inform them about the potential treatment-induced gonadotoxicity as well as the available strategies for fertility preservation, thus allowing to increase the chances of a future pregnancy.

Background: Massive weight loss (MWL) has a positive impact on the comorbidities associated with obesity but leaves patients with ongoing body issues due to skin excess. Almost all patients present some degree of breast ptosis and breast volume deficiency, which can be addressed with different techniques including autologous flaps., Material and Methods: A literature search was conducted by using PubMed, Google Scholar, and Cochrane databases. Patient's characteristics, type of bariatric surgery, amount of weight loss, flap size and design, simultaneous breast and extra-breast procedures were analyzed. Aesthetic and patient-reported outcomes, postoperative complications, revision rate, and donor site morbidity were also registered., Results: Twelve articles fulfilled inclusion criteria, and 79 patients were included, for a total of 157 flaps. Different flap designs and flap combinations were described; those originating from lateral chest wall area were the most commonly used. Simultaneous breast procedures were reported in 72 patients. Simultaneous extra-breast body contouring (BC) procedure was performed in 40 cases. The overall complication rate was 9.55% and a total of ten revisionary procedures were performed. Satisfaction of the patients was globally quite high., Conclusions: Advantages of the use of autologous tissue in breast reshaping after MWL is the avoidance of implant-related complications and the simultaneous improvement of the silhouette. The complication rate resulted in acceptable, aesthetic, and patient-reported outcomes resulted to be encouraging, even if there was a lack of standardization in the evaluation. A comparative randomized study to confront the use of autologous flaps combined with mastopexy versus the use of implants combined with mastopexy can be useful to confirm the promising results., Level of Evidence Iii: This journal requires that authors assign a level of evidence to each article.

Immunotherapy has changed the landscape of treatments for advanced disease in multiple neoplasms. More and more patients are long survivors from a metastatic disease. Most recently, the extension of indications and evidence of efficacy in early disease settings, such as the adjuvant and neoadjuvant setting in breast cancer, lung cancer, glioma, and gastric cancer, places more attention on what happens to patients who survive cancer. In particular, we evaluated what happens in young patients, a population in whom some immune-related effects are still poorly described. Immunotherapy is already a reality in early disease settings and the scientific community is lagging in describing what to expect in adolescent and young adult (AYA) patients. For instance, the impact of these therapies on female and male fertility is not clear, similarly to the interaction that may occur between these drugs and pregnancy. This review aims to highlight these little-known topics that are difficult to evaluate in ad hoc studies., Competing Interests: CG received honoraria from Astra Zeneca, Bristol-Myers-Squibb, Merck-Sharp-Dohme, Roche, and Boehringer-Ingelheim.

A significant number of women receive a cancer diagnosis before their age of natural menopause. Among these patients, the most frequent neoplasms are breast cancer, gynecological, and hematological malignancies. Premature ovarian insufficiency and infertility are among the most feared short- to long-term consequences of anticancer treatments in premenopausal patients. Both patient- and treatment-related characteristics are key factors in influencing the risk of gonadotoxicity with the use of chemotherapy. The cryopreservation of oocytes/embryos is a standard strategy for fertility preservations offered to young women interested in future family planning, but it does not allow gonadal function protection during chemotherapy. Ovarian suppression with gonadotropin-releasing hormone agonist (GnRHa) during chemotherapy is now recommended as an option to reduce the risk of gonadotoxicity in order to avoid the negative consequences of premature ovarian insufficiency in premenopausal women receiving cytotoxic therapy, including those not interested in fertility preservation. This review summarizes the risk of treatment-induced gonadotoxicity in premenopausal patients and the evidence available on the protective role of administering GnRHa during chemotherapy to preserve ovarian function.

Background: Whether the extent of residual disease in the sentinel lymph node (SLN) after neoadjuvant chemotherapy (NAC) influences the prognosis in clinically node-positive breast cancer (BC) patients remains to be ascertained., Methods: One hundred and thirty-four consecutive cN+/BC-patients received NAC followed by SLN biopsy and axillary lymph node dissection. Cumulative incidence of overall (OS) and disease-free (DFS) survival, BC-related recurrences and death from BC were assessed using the Kaplan-Meier method both in the whole patient population and according to the SLN status. The log rank test was used for comparisons between groups., Results: The SLN was identified in 123/134 (91.8%) patients and was positive in 98/123 (79.7%) patients. Sixty-five of them (66.3%) had other axillary nodes involved. SLN sensitivity and false-negative rate were 88.0% and 2.0%, Median follow-up was 10.2 years. Ten-year cumulative incidence of axillary, breast and distant recurrences, and death from BC were 6.5%, 11.9%, 33.4% and 31.3%, respectively. Ten-year OS and DFS were 67.3% and 55.9%. When stratified by SLN status, 10-year cumulative incidence of BC-related and loco-regional events, and death from BC were similar between disease-free SLN and micrometastatic SLN subgroups (28.9% vs 30.2%, p = 0.954; 21.6% vs 13.4%, p = 0.840; 12.9 vs 24.5%, p=0.494). Likewise, 10-year OS and DFS were comparable (80.0% vs 75.5%, p=0.975 and 68.0% vs 69.8, p=0.836). Both OS and DFS were lower in patients presenting a macrometastatic SLN (60.2% and 47.5%)., Conclusion: Outcome of patients with micrometastatic SLN was similar to that of patients with disease-free SLN, which was more favorable as compared to that of patients with macrometastatic SLN., Competing Interests: Declaration of competing interest None of the authors declares conflicts of interest., (Copyright © 2021.

Introduction: Aromatase inhibitors are effective in lowering breast cancer incidence among postmenopausal women, but adverse events represent a barrier to their acceptability and adherence as a preventive treatment. This study aims to assess whether lowering exemestane schedule may retain biological activity while improving tolerability in breast cancer patients., Methods/design: We are conducting a, pre-surgical, non-inferiority phase IIb study in postmenopausal women with newly diagnosed estrogen receptor-positive breast cancer. Participants are randomized to receive either exemestane 25 mg/day or 25 mg/three times-week or once a week for 4 to 6 weeks prior to surgery. The primary endpoint is the percentage change of serum estradiol concentration between baseline and surgery comparing the three arms. Sample size of 180 women was calculated assuming a 6% non-inferiority of the percent change of estradiol in the lower dose arms compared with the 80% decrease predicted in the full dose arm, with 80% power and using a one-sided 5% significance level and a two-sample t-test. Main secondary outcomes are: safety; change in Ki-67 in cancer and adjacent pre-cancer tissue, circulating sex hormones, adipokines, lipid profile, insulin and glucose changes, in correlation with drug and metabolites concentrations., Results and Discussion: The present paper is focused on methodology and operational aspects of the study. A total of 180 participants have ben enrolled. The trial is still blinded, and the analyses are ongoing. Despite the short term duration, results may have relevant implications for clinical management of women at increased risk of developing a ER positive breast cancer., (Copyright © 2021 The Authors.
