Introduction: Metastatic breast cancer (MBC) presents an enduring and significant challenge for affected women, requiring sustained commitment over the years. Case Presentation: This paper presents a case of a woman affected by bone and visceral MBC with a very long 20-year survival, excellent quality of life, and high resilience. She is now 51 years old and underwent quadrantectomy for breast cancer in 2005, and in 2013, she developed a recurrence with bone and liver metastases. Despite the widespread stage of the disease with visceral compromise, the patient was treated with a multidisciplinary approach that included surgery, chemotherapy, radiotherapy, hormone therapy, bone target agents, metabolic radiotherapy, and ozone therapy for medication-related osteonecrosis of the jaw. Multidisciplinary management results in a complete clinical and metabolic response to treatment in a visceral metastatic setting. Conclusion: This report supports the possibility of achieving unusual survival outcomes in patients with MBC. This study also highlights the importance of resilience in breast cancer patients who continue to manage their disease and pursue treatment for over 2 decades. Understanding these resilience factors can improve clinical practice and support patients’ long-term care. [ABSTRACT FROM AUTHOR]

Simple Summary: Axillary management in breast cancer has undergone significant changes over the past decades, especially with the introduction of neoadjuvant chemotherapy (NACT). NACT aims to shrink tumors before surgery, allowing for less invasive axillary approaches such as sentinel lymph node biopsy (SLNB) and targeted axillary dissection (TAD). These techniques help reduce the need for axillary lymph node dissection (ALND), which is associated with higher risks of complications like lymphedema. However, patient selection for these procedures depends on factors such as tumor biology, response to NACT, and the extent of nodal disease. This review discusses the latest evidence supporting de-escalation strategies in axillary surgery and highlights ongoing research that aims to further refine the selection criteria for these approaches. Multidisciplinary collaboration remains key to implementing personalized treatments that optimize patient outcomes while minimizing surgical morbidity. Background. In breast cancer (BC) patients, axillary management has undergone major improvements over the last few years, and efforts to identify the optimal strategy for the management of axillary surgery are still ongoing. Methods. In current clinical practice, women with clinically node-positive (cN+) BC usually receive neoadjuvant chemotherapy (NACT) with the aim of reducing the extent of primary disease and, thus, allowing for axillary-conservative surgery. Remarkably, after NACT, up to one out of three patients achieves an axillary pathologic complete response, which, in turn, is associated with a more favorable prognosis than residual axillary disease. However, NACT is not without drawbacks, as NACT-associated inflammation can damage lymphatic vessels. Furthermore, varying degrees of response may occur in the axillary lymph nodes, increasing the false negative rate for sentinel biopsy. Results. At present, there is no consensus on the optimal approach in patients with cN+ BC undergoing NACT, although multidisciplinary management seems to be recommended. Conclusions. This narrative review provides a comprehensive overview of axillary management in cN+ BC patients undergoing NACT. It uses a multidisciplinary approach that encompasses the oncological management perspectives, as well as surgical and chemotherapeutic viewpoints. [ABSTRACT FROM AUTHOR]

Introduction: Metronomic oral cyclophosphamide (MOC) presents many potential advantages, such as significantly less severe side effects than standard regimens, ease of administration, and the delivery of a dose-dense but not necessarily dose-intense treatment. These observations prompted us to evaluate in a retrospective, multicenter study the efficacy and toxicity of MOC in a real-life series of pretreated cancer patients. Methods: The study is a multicenter, retrospective analysis of the activity of single-agent MOC in patients with recurrent or residual epithelial ovarian, fallopian tube, or primary. Eligible patients were continuously treated with MOC at 50 mg/day until progression, toxicity, or death. Overall response rate (ORR), stable disease (SD), and disease control rate (DCR) were reported. Results: The study included 62 patients. Three patients reached a complete response rate (5%), 11 had a partial response rate (18), and 15 had stabilization of disease (24) for an ORR of 23% and a DCR of 47%. Patients with low-grade indolent tumors showed an ORR and an SD rate higher than that observed in non-indolent ones (33% vs. 18% and 28% vs. 14%, respectively). Overall, progression-free survival was 3.5 months (range 1–9 months). Conclusion: Single-agent MOC is active and very well tolerated in a significant fraction of patients with refractory, recurrent, or residual epithelial ovarian, fallopian tube, or primary peritoneal cancer. In the vision of a practical approach, single-agent MOC may be a useful palliative treatment option for patients with poor tolerance to high-dose regimens or widely pretreated. Further studies are needed better to characterize the role of such an approach in clinical practice. [ABSTRACT FROM AUTHOR]

Simple Summary: Brain metastases are a major challenge for patients with HER2+ breast cancer. Traditional treatments, like radiotherapy, can help but often cause severe side effects and may not provide lasting control. Researchers are exploring new, more precise treatments, including antibodies, drug-antibody combinations, and small molecule drugs that can better penetrate the brain. These new therapies have shown promise in clinical trials, helping to control brain tumors more effectively and with fewer side effects than radiotherapy. The goal of this review is to improve treatments for HER2+ breast cancer patients who develop brain metastases, enhancing their survival rates and quality of life. The findings from this research could significantly impact the medical community by offering better alternatives to radiotherapy and improving how brain metastases are managed. This progress could provide new hope for patients facing this challenging condition and potentially transform treatment strategies in the future. Brain metastases (BM) pose a significant challenge in the management of HER2+ breast cancer since almost 50% of patients with HER2+ breast cancer develop brain tumors. The complex process of brain metastases involves genetic mutations, adaptations and mechanisms to overcome the blood–brain barrier. While radiotherapy is still fundamental in local therapy, its use is associated with cognitive adverse effects and limited long-term control, necessitating the exploration of alternative treatments. Targeted therapies, including tyrosine kinase inhibitors, monoclonal antibodies, and antibody–drug conjugates, offer promising options for HER2+ breast cancer patients with BM. Clinical trials have demonstrated the efficacy of these agents in controlling tumor growth and improving patient outcomes, posing the question of whether radiotherapy is always the unique choice in treating this cancer. Ongoing research into novel anti-HER2 antibodies and innovative combination therapies holds promise for advancing treatment outcomes and enhancing patient care in this clinical scenario. This narrative review provides a comprehensive overview of traditional medical treatments, molecularly targeted therapy and investigational agents in the management of HER2+ breast cancer with BM, highlighting the evolving landscape and potential future directions in treatment strategies to improve patient survival and quality of life.

Sarcopenia is a prevalent and clinically significant condition, particularly among older age groups and those with chronic disease. Patients with cancer frequently suffer from sarcopenia and progressive loss of muscle mass, strength, and function. The complex interplay between cancer and its treatment, including medical therapy, radiotherapy, and surgery, significantly contributes to the onset and worsening of sarcopenia. Cancer induces muscle wasting through inflammatory processes, metabolic alterations, and hormonal imbalance. Moreover, medical and radiation therapies exert direct toxic effects on muscles, contributing to the impairment of physical function. Loss of appetite, malnutrition, and physical inactivity further exacerbate muscle wasting in cancer patients. Imaging techniques are the cornerstones for sarcopenia diagnosis. Magnetic resonance imaging, computed tomography, and dual-energy X-ray absorptiometry provide valuable insights into muscle structure and quality. Although each modality has advantages and limitations, magnetic resonance imaging produces high-resolution images and provides dynamic information about muscle function. Despite these challenges, addressing sarcopenia is essential for optimizing treatment outcomes and improving survival rates in patients with cancer. This review explored the factors contributing to sarcopenia in oncologic patients, emphasizing the importance of early detection and comprehensive management strategies. [ABSTRACT FROM AUTHOR]

Introduction: In recent years, generative Artificial Intelligence models, such as ChatGPT, have increasingly been utilized in healthcare. Despite acknowledging the high potential of AI models in terms of quick access to sources and formulating responses to a clinical question, the results obtained using these models still require validation through comparison with established clinical guidelines. This study compares the responses of the AI model to eight clinical questions with the Italian Association of Medical Oncology (AIOM) guidelines for ovarian cancer. Materials and Methods: The authors used the Delphi method to evaluate responses from ChatGPT and the AIOM guidelines. An expert panel of healthcare professionals assessed responses based on clarity, consistency, comprehensiveness, usability, and quality using a five-point Likert scale. The GRADE methodology assessed the evidence quality and the recommendations' strength. Results: A survey involving 14 physicians revealed that the AIOM guidelines consistently scored higher averages compared to the AI models, with a statistically significant difference. Post hoc tests showed that AIOM guidelines significantly differed from all AI models, with no significant difference among the AI models. Conclusions: While AI models can provide rapid responses, they must match established clinical guidelines regarding clarity, consistency, comprehensiveness, usability, and quality. These findings underscore the importance of relying on expert-developed guidelines in clinical decision-making and highlight potential areas for AI model improvement. [ABSTRACT FROM AUTHOR]

Objective: Oral metronomic cyclophosphamide has been used as a single agent or in combination with other drugs for several solid tumors with interesting results in disease palliation and mild to moderate toxicity, notably in patients with recurrent epithelial ovarian cancer (EOC) progressing after systemic chemotherapy. In this paper, we report a review and a metanalysis of heterogeneous data published up to date. Data sources: The literature search was restricted to single-agent MOC. The analysis was conducted through March 2023 by consulting PubMed, Embase, Google Scholar, and The Cochrane Library databases. Research string and Medical Subject Headings included "ovarian tumor," "ovarian carcinoma," or "ovarian cancer," "fallopian tube cancer," "primary peritoneal cancer," "oral chemotherapy," and "metronomic cyclophosphamide." All articles were assessed for quality by at least two investigators independently, and a < 18 patients sample size cutoff was chosen as a lower limit with a Cohen's kappa statistical coefficient for accuracy and reliability. Metanalysis of selected papers was carried out according to a fixed model. Data summary: The percentage of agreement between investigators on literature study selection was very high, reaching 96.9% with a Cohen's k of 0.929. MOC pooled objective response rate (ORR) and disease control rate for recurrent or platinum-refractory ovarian cancer were 18.8% (range 4–44%) and 36.2% (range 16–58.8%), respectively. The mean progressive-free survival and overall survival were 3.16 months (range 1.9 to 5.0 months) and 8.7 months (range 8 to 13 months), respectively. The fixed model metanalysis of selected studies showed a 16% median ORR (12–20% CI, p < 0.001). Conclusions: Single-agent oral cyclophosphamide in EOC holds promise as a treatment option, even in the era of precision medicine. Genetic factors, such as DNA repair gene polymorphisms, may influence treatment response. Combining cyclophosphamide with biological agents such as PARP inhibitors or immunotherapy agents is an area of active investigation. [ABSTRACT FROM AUTHOR]

Introduction: Breast cancer (BC) is one of the most common tumors; better screening policies and multidisciplinary approach allow personalized treatment. Radiotherapy (RT) plays a central role in the multimodal approach in BC, and recent evidence has shown the non-inferiority of hypofractionated treatments. The aim of this study was to describe the feasibility and validity of stereotactic RT (SBRT) in BC in a neoadjuvant and exclusive setting. Methods: A PubMed/MEDLINE and Embase systematic review was conducted to assess the role of radiomics in BC. The search strategy was "breast [All Fields] AND "stereotactic" [All Fields] AND "radiotherapy" [All Fields]" and only original articles referred to BC in humans in the English language were considered. Results: A total of 2,149 studies were obtained using the mentioned search strategy on PubMed and Embase. After the complete selection process, a total of 12 papers were considered eligible for the analysis of the results. SBRT in BC was described in 8 studies regarding neoadjuvant approach and 4 papers regarding exclusive approach. Conclusions: Relative low toxicity rates, the reduced treatment volumes in the neoadjuvant setting, and the possibility to replace surgery when not feasible in exclusive setting resulted to be main advantages for SBRT in BC. Current evidence shows that both the neoadjuvant and the definitive settings seem to be promising clinical scenarios for SBRT, especially for EBC. [ABSTRACT FROM AUTHOR]

Immune checkpoint inhibitor (ICI) therapy has revolutionized cancer treatment by enhancing the immune response against tumor cells. However, their influence on immune pathways can lead to immune-related adverse events such as pneumonitis, necessitating rapid diagnosis and management to prevent severe complications. These adverse events arise from the activation of the immune system by immunotherapeutic drugs, leading to immune-mediated inflammation and tissue damage in various organs and tissues throughout the body. The present review article discusses the pathophysiology, clinical presentation, diagnostic modalities and management strategies for ICI-related pneumonitis, emphasizing early recognition and tailored interventions. Future research endeavors should focus on elucidating the underlying mechanisms of pneumonitis and identifying predictive biomarkers to guide personalized treatment strategies in this evolving field of oncology.
