The orbit represents an unusual metastases site for patients diagnosed with cancer, however, breast cancer is the main cause of metastases at this level. These orbital metastases were discovered in patients with a history of breast cancer as unique or synchronous lesions. We present a rare case of a unique retroocular metastasis as the first initial symptom of a tubulo-lobular mammary carcinoma in a postmenopausal woman. A 57-year-old patient complains of diplopia, diminishing visual acuity, orbital tenderness, slight exophthalmia and ptosis of the left eyelid, with insidious onset. Clinical examination and subsequent investigations revealed a left breast cancer cT2 cN1 pM1 stage IV. Breast conserving surgery was performed on the left breast. Pathological examination with immunohistochemistry staining established the complete diagnostic: pT2pN3aM1 Stage IV breast cancer, luminal B subtype. After two years from the initial breast cancer diagnosis, the patient was diagnosed by the psychiatrist with a depressive disorder and was treated accordingly. Orbital metastases are usually discovered in known breast cancer patients and they are found in the context of a multi-system end-stage disease. Most reports cite that up to 25% of the total orbital metastases cases are discovered before the diagnosis of the primary tumor, as our case did. MRI is the gold standard for evaluating orbital tumors. The ILC histological subtype metastasizes in the orbitals more frequently than invasive ductal carcinoma. The prognosis of patients with orbital metastases is poor. The median survival after diagnosis of orbital metastases from a breast cancer primary is ranging from 22 to 31 months. Overall survival of our patient was 56 months, longer than the median survival reported in literature. Orbital metastases must be taken into account when patients accuse ophthalmologic symptoms even in the absence of a personal history of cancer. Objective examination of every patient that incriminates these types of symptoms is essential, and breast palpation must be made in every clinical setting. Orbital biopsy is necessary for the confirmation of the diagnosis and for an adequate treatment. Although recommendations for management of orbital metastases are controversial, it appears that multidisciplinary treatment of both metastases and primary cancer improves overall survival.

The safety profile and effectiveness of existing anti-HER2-targeted therapies have not been evaluated in patients with breast cancer and visceral crisis. We report the case of a 26-year-old woman who was diagnosed with advanced HER2-positive breast cancer and initially treated with curative intent therapy in a neoadjuvant setting, using Trastuzumab and Pertuzumab in combination with Docetaxel; her cancer recurred two years later, with liver metastases and pulmonary lymphangitic carcinomatosis, causing visceral crisis. Furthermore, the patient’s clinical status worsened when she developed respiratory failure, hepatomegaly and a severe hepatocytolysis. Since the patient was free of disease more than six months, we started with Paclitaxel half dose because of the hepatic dysfunction, and we gradually reintroduced Trastuzumab and then Pertuzumab. In the meantime, the patient changed her lifestyle by increasing her consumption of fresh fruits and vegetables and fiber and reducing her intake of processed meat, dairy and sugar. As a result, the patient showed a significant improvement in her respiratory symptoms and liver tests in less than two months. Imaging reevaluation showed partial remission of liver metastases and pulmonary lymphangitic carcinomatosis. She underwent seven months of dual anti-HER2 blockade before relapsing cerebrally. Our results suggest that the sequential combination therapy with Trastuzumab, Pertuzumab and Paclitaxel presented in this study, associated with a healthy lifestyle, may be a good management for recurrent HER2-positive breast cancer with pulmonary visceral crisis and severe liver dysfunction.

Background/Objectives: Cyclin-dependent kinase 4/6 inhibitors combined with endocrine therapy have become the standard of care for HR+/HER2− metastatic breast cancer. Given the metabolic functions of CDK4/6 and the endocrine activity of adipose tissue, body mass index has been proposed as a potential prognostic or predictive factor in this setting. This systematic review aimed to summarize current evidence on the association between BMI and treatment outcomes in HR+/HER2− MBC patients receiving CDK4/6i. Methods: A systematic literature search was conducted in PubMed and Scopus databases, covering publications from 2015 to 2025. We included real-world studies and clinical cohorts reporting survival outcomes of HR+/HER2− MBC patients treated with CDK4/6i in relation to BMI and other body composition parameters. Results: From 69 records identified, 14 studies met the inclusion criteria. Findings were heterogenous; four studies reported improved survival outcomes in higher BMI patients, whereas most identified no significant association. Studies incorporating computed tomography-based metrics demonstrated that body composition parameters such as visceral adiposity and skeletal muscle area were more reliable predictors of prognosis than BMI alone. Conclusions: Our findings indicate that BMI as a standalone metric is an insufficient predictor of clinical outcomes or treatment response for those receiving CDK4/6i, highlighting the need for precise body composition evaluation. More detailed anthropometric and metabolic profiling could clarify the clinical significance of adiposity in HR+/HER2− MBC.

With improved survival, more patients with prior breast cancer are at risk of having a second primary cancer diagnosed. The pattern and impact of second primary cancers following breast cancer is important for overall breast cancer therapeutic management. Our study is a first analysis of the trend of second primary tumours over time in terms of incidence, sites with significantly elevated risks and correlation with stage, molecular subtype and therapeutic strategies conducted in Eastern Europe in postmenopausal women with breast cancer. Patients and methods: Our study population included 28 patients with prior breast cancer (BC) and second primary tumours, which were diagnosed and treated in our Institution between 2004 and 2017. The criteria for selection were based on the completeness of the documentation of the first treatment for breast cancer, stage of disease, molecular subtype, the site of origin of the second tumours and the survival data. Results: An increased risk of second primary cancer was associated with the 51–60 years age group (53.6%), with the greater prevalence in patients living in urban environments (82.1%). The use of chemotherapy increased the risk of the occurrence of gynecological second malignancies (75%). Our study is a first analysis of the trend of second primary tumours over time in terms of identifying sites with significantly elevated risks and correlation with therapeutic strategies conducted in Eastern Europe in postmenopausal women with breast cancer. Conclusions: Our study is a first analysis of the trend of second primary tumours over time in terms of correlation with luminal subtype and stage at diagnosis of primary cancer sites with significantly elevated risks and correlation with therapeutic strategies in postmenopausal women with breast cancer conducted in Eastern Europe. The reported time from primary to second primary malignancy onset, with a significantly higher rate for postmenopausal breast cancer patients, was less than one year (50%). With the advances and wider availability of genetic testing (e.g., gene panels), patients diagnosed with multiple primaries should be increasingly investigated for an underlying cancer predisposition. Postmenopausal women with breast cancer may benefit from increased surveillance and advice to avoid second malignancies.

Background: Palbociclib, when combined with endocrine therapy, represents a valuable treatment option for patients diagnosed with hormone receptor (HR) positive/human epidermal growth factor receptor 2 (HER2) negative advanced breast cancer (BC) or metastatic breast cancer (MBC). Approved in Europe following phase II/III trials, it became the first CDK4/6 inhibitor used alongside hormone therapy. Available real-world data demonstrate the strong performance of Palbociclib in unselected, heavily pretreated patient groups. Our retrospective, observational, multicenter study, conducted in six Romanian institutions during a follow-up period of 2.5 years, aimed to assess Palbociclib’s safety and effectiveness in clinical practice. Objectives: The primary endpoints included response rate such as overall response rate (ORR), duration of response (DOR), disease control rate (DCR) and best clinical response (BCR), progression free survival (PFS) and overall survival (OS). The secondary objectives focused on treatment duration with aromatase inhibitors (AI) or fulvestrant and subsequent therapies after disease progression. Grade 3/4 adverse events were individually recorded. Exploratory analysis evaluated the potential predictive biomarkers such as Ki67, lower levels of HER2 expression (HER2-low), and histological or luminal subtype. Methods: Approximately 650 patients were planned for inclusion. PFS and OS were analyzed via the Kaplan–Meier method, with median times, 1- and 2-year estimates, and 95% confidence intervals reported. Conclusions: This study supports the integration of clinical trial evidence into real-world settings, enhancing patient selection and treatment personalization.

Background: Breast cancer mortality and long-term survival are influenced by the unpredictability of recurrences, which cause significant diagnostic and therapeutic challenges for oncology teams. The risk of local and distant recurrence is higher in advanced stages and in the first two years following initial treatment. Accurate staging and continuous monitoring of recurrence are crucial for effective therapy planning. Indicators of recurrence, such as luminal subtype, disease stage, age, and treatment choice, can provide new knowledge and improve patient disease-free and overall survival rates. Methods: We conducted a retrospective cohort study of patients with stage I-III invasive breast cancer at a regional-based institution. The study population consisted of 98 patients with distant and locoregional recurrences from a large cohort of 744 patients diagnosed and treated at our institution between 2007 and 2024. Data on previous treatment for breast cancer, disease stage, molecular subtype, initial size and location of the tumor in the breast, lymph node status, living environment, and type of recurrence were recorded retrospectively. Results: The recurrence patterns in 98 patients included local recurrence in 25 (25.5%), distant recurrence in 70 (71.4%), and both local and distant recurrence in three (3.1%). Our study showed that patients diagnosed with stage II (40.8%) or stage III (55.1%) breast cancer, as well as those with the luminal B subtype (43.87%), were more likely to experience recurrence. The majority of patients affected by recurrent disease were postmenopausal women aged between 51 and 70 years (32 cases aged 51–60 years and 34 cases aged 61–70 years). Tumors measuring between 2 and 5 cm were more likely to produce distant single-organ recurrence (26 cases). More cases were associated with urban areas (77 cases). Conclusions: In menopausal women, most causes of local breast cancer recurrence are related to advanced stage at diagnosis and luminal B subtype. Patient age, primary tumor location in the CSE, and previous adjuvant treatment with aromatase inhibitors may affect the risk of recurrence. Comprehensive studies on recurrence in postmenopausal women can provide a more precise understanding of the extent of disease in such patients.
