Horner's syndrome: An unusual presentation of metastatic disease in breast cancer.

Horner's syndrome (HS) is caused by an interruption of the cervical sympathetic pathway to the eye and the face. Acquired HS is mainly caused by benign or malignant neoplasms, and in patients with a history of cancer, it is almost always the result of tumor infiltration into the periphery or the central region of the cervical sympathetic chain.We present the case of a 52-year-old patient with long-term disease-free survival (6 years) after a radical mastectomy for breast cancer who presented with cervicobrachialgia and typical HS due to a left lateral-cervical and supraclavicular lymph nodal mass. Treatment of the metastatic disease with taxanes and concurrent trastuzumab resulted in a complete pain resolution, as well as long-term clinical and radiologic remission; however, the neurological cohort of HS remained as the expression of permanent damage to the sympathetic pathway.This report presents a highly rare case of HS as the first and solitary appearance of metastatic disease in a breast cancer patient. This neurologic involvement should always raise suspicion of metastatic infiltration, and the early recognition of the syndrome may prevent permanent nerve injury.

Effect of splenectomy on iron balance in patients with ß-thalassemia major: a long-term follow-up.

OBJECTIVE: A retrospective study was performed to explore the effect of splenectomy on iron balance in thalassemia major (TM). METHODS: Twenty two TM patients treated with splenectomy were compared with a control group (non-splenectomized patients) matched for sex, age, pretransfusional Hb, chelation therapy, and duration of follow-up in a retrospective study to evaluate blood consumption, iron intake, and serum ferritin during an overall observation period of 6 yrs before and 10 yrs after splenectomy. RESULTS: Splenectomy improved parameters of iron balance, determining a significant reduction in blood consumption (P < 0.01), iron intake (P < 0.01), and serum ferritin (P < 0.01). Comparing the two groups, blood consumption and iron intake were similar in presplenectomy period (P > 0.05), but serum ferritin was significantly higher in splenectomized patients (P < 0.01). After splenectomy, blood consumption and iron intake were significantly lower (P < 0.01) in splenectomized group while serum ferritin did not differ significantly (P > 0.05) between two groups, except for the first year (P < 0.05). CONCLUSION: Splenectomy determines immediate drop in blood consumption and iron intake but slow downtrend of ferritin; direct measurements of iron overload, such as magnetic resonance studies, are needed to better understand the effect of splenectomy on iron balance parameters. Tailoring chelation therapy and eventually its intensification seem more efficient measures to manage iron accumulation in TM and to lower iron level to safety threshold.

Safety and efficacy of tomosynthesis-guided breast biopsies in the prone position: monocentric study and review of the literature.

PURPOSE: The purpose of this study is to describe the safety and efficacy of 9G needle biopsy under tomosynthesis guidance with the patient in the prone position. MATERIALS AND METHODS: This is a retrospective observational study conducted on patients with non-palpable breast mass exclusively detectable through tomosynthesis, performed from the 1st January 2018 to the 1st August 2020. The procedures were performed by taking 12 tissue samples from each mass. The evaluated technical success was considered as a conclusive sample for histological diagnosis. We performed a comparison between the procedural data of interventions in patients who have a lesion < or = 10 mm and > 10 mm and between high-contrast and low-contrast masses. The histological data of the samples were analyzed. RESULTS: Five hundred biopsies of the total 1500 performed from the 1st January 2018 to the 1st August 2020 were included in the study; repetitions for inadequate withdrawal occurred 0.4% (3/500). No major complications have ever been observed. Two cases (0.2%) of minor bleeding were observed with self-limited bleeding from the skin breach at 90 min without clinical sequelae in an asymptomatic patient. The biopsy samples showed carcinoma in 55.2% (276/500). CONCLUSION: Our study suggests that the 9G needle sampling biopsy procedure through tomosynthesis guide with prone patient is a safe and effective procedure for the characterization of indeterminate breast mass.

Pre-Menopausal Breast Fat Density Might Predict MACE During 10 Years of Follow-Up: The BRECARD Study.

OBJECTIVES: This study sought to determine whether the breast gland adipose tissue is associated with different rates of major adverse cardiac events (MACEs) in pre-menopausal women. BACKGROUND: To our knowledge, no study investigated the impact of breast adipose tissue infiltration on MACEs in pre-menopausal women. METHODS: Prospective multicenter cohort study conducted on pre-menopausal women >40 years of age without cardiovascular disease and breast cancer at enrollment. The study started in January 2000 and ended in January 2009, and the end of the follow-up for the evaluation of MACEs was in January 2019. Participants underwent mammography to evaluate breast density and were divided into 4 groups according to their breast density. The primary endpoint was the probability of a MACE at 10 years of follow-up in patients staged for different breast deposition/adipose tissue deposition. RESULTS: The propensity score matching divided the baseline population of 16,763 pre-menopausal women, leaving 3,272 women according to the category of breast density from A to D. These women were assigned to 4 groups of the study according to baseline breast density. At 10 years of follow-up, we had 160 MACEs in group 1, 62 MACEs in group 2, 27 MACEs in group 3, and 16 MACEs in group 4. MACEs were predicted by the initial diagnosis of lowest breast density (hazard ratio: 3.483; 95% confidence interval: 1.476 to 8.257). Further randomized clinical trials are needed to translate the results of the present study into clinical practice. The loss of ex vivo breast density models to study the cellular/molecular pathways implied in MACE is another study limitation. CONCLUSIONS: Among pre-menopausal women, a higher evidence of adipose tissue at the level of breast gland (lowest breast density, category A) versus higher breast density shows higher rates of MACEs. Therefore, the screening mammography could be proposed in overweight women to stage breast density and to predict MACEs.

Sublingual immunotherapy in children with allergic polysensitization.

Polysensitization is quite frequent in allergic children and may cause difficulties for the allergist in prescribing allergen-specific immunotherapy. This study aimed at evaluating the clinical effectiveness of 1 year of sublingual immunotherapy (SLIT) in a cohort of Italian allergic children with polysensitization. This open study was performed on 51 polysensitized children (34 boys; mean age, 11.8 years; range, 5.2-17.7 years) with allergic rhinitis and/or mild to moderate asthma. All of them were treated with SLIT for 1 year. The kind and the number of prescribed allergen extracts, the type of diagnosis, the severity of symptoms, and the use of drugs were evaluated at baseline and after 1 year. The adverse events to SLIT were also evaluated. Forty-two children were treated with a single extract, four with two different extracts and three with a mix of allergens. SLIT treatment induced a significant reduction in the number of sensitizations (p = 0.018); significant improvement of allergic rhinitis classification and severity; significant reduction of ocular, nasal, and bronchial symptoms (p < 0.01 for all); and drugs use (p < 0.01 for all drugs). No systemic reactions to SLIT were observed. This open study provides evidence that polysensitization is not an obstacle for prescribing SLIT in polysensitized children. Indeed, SLIT efficacy on clinical parameters is significant after 1 year and the therapy is safe.

18FDG-PET for early prediction of complete response to lapatinib and capecitabine in HER2-positive metastatic breast cancer: a case report.

Targeted therapies against HER2 (trastuzumab, lapatinib) have improved the efficacy of treatment and the outcome of patients with HER2-positive breast cancer. Lapatinib is a tyrosine kinase inhibitor targeting EGFR1 and HER2: it binds the intracellular domain of these receptors and blocks their downstream signaling pathways. In combination with capecitabine, it is the standard of care for patients with trastuzumab-resistant advanced breast cancer. We present the case of a patient exhibiting a complete and prolonged clinical response to second-line treatment with lapatinib and capecitabine after failure of trastuzumab-based therapy. 18FDG-PET allowed the detection of disease remission several months before computed tomography. Molecular imaging with 18FDG seems the most powerful way to measure the pharmacodynamic effects of targeted anticancer drugs. This case report confirms that 18FDG-PET plays a key role not only in detecting metastatic disease but also in evaluating the response to HER2-directed therapy.
