Invasive lobular breast cancer: Focus on prevention, genetics, diagnosis, and treatment.

Invasive lobular cancer (ILC) is the most common of the breast cancer special types, accounting for up to 15% of all breast malignancies. The distinctive biological features of ILC include the loss of the cell adhesion molecule E-cadherin, which drives the tumor's peculiar discohesive growth pattern, with cells arranged in single file and dispersed throughout the stroma. Typically, such tumors originate in the lobules, are more commonly bilateral compared to invasive ductal cancer (IDC) and require a more accurate diagnostic examination through imaging.

Metaplastic breast cancer: an all-round multidisciplinary consensus.

Metaplastic breast cancer (MpBC) is a rare and aggressive histologic subtype of breast cancer (BC) characterized by the presence of at least two cellular types, commonly epithelial and mesenchymal components. Despite growing evidence that MpBC is a unique entity, it has long been treated as a variant of nonspecial type (NST) BC. MpBC typically shows the phenotype of triple-negative breast cancer (TNBC), but compared to NST-TNBC, it is a relatively chemorefractory tumor associated with worse outcomes.

Antitumor T-cell function requires CPEB4-mediated adaptation to chronic endoplasmic reticulum stress.

Tumor growth is influenced by a complex network of interactions between multiple cell types in the tumor microenvironment (TME). These constrained conditions trigger the endoplasmic reticulum (ER) stress response, which extensively reprograms mRNA translation. When uncontrolled over time, chronic ER stress impairs the antitumor effector function of CD8 T lymphocytes.

Successful retrieval of a needle point from the breast through a vacuum-assisted breast biopsy system.

Stereotactic vacuum-assisted breast biopsy (VABB) system is generally used to perform breast biopsies after identifying suspicious lesions that are occult on ultrasound. In this case, we used an 8-Gauge VABB to retrieve a needle point retained in the outer-lower quadrant of the right breast of a patient previously treated with lumpectomy. The use of stereotactic VABB system in this specific clinical setting has been never described before and resulted minimally invasive and perfectly suitable for correct localisation and retrieval of the 3-mm needle point; moreover, it may be easily reproduced elsewhere.

Local treatment in patients with hereditary breast cancer: decision-making process in low-, moderate-, high-penetrance pathogenic germline mutation carriers.

Purpose Of Review: We summarize recent evidence regarding commonly tested breast cancer susceptibility genes and review indications derived from recently published guidelines regarding management of carriers affected by early breast cancer (BC).

Recent Findings: Management of affected women with a known genetic predisposition to BC was matter of debate at the most relevant international conferences, such as St. Gallen International Consensus Conference and San Antonio Breast Cancer Symposium held both in 2021.

Macrophage inflammation resolution requires CPEB4-directed offsetting of mRNA degradation.

Chronic inflammation is a major cause of disease. Inflammation resolution is in part directed by the differential stability of mRNAs encoding pro-inflammatory and anti-inflammatory factors. In particular, tristetraprolin (TTP)-directed mRNA deadenylation destabilizes AU-rich element (ARE)-containing mRNAs.

Immune translational control by CPEB4 regulates intestinal inflammation resolution and colorectal cancer development.

Upon tissue injury, cytokine expression reprogramming transiently remodels the inflammatory immune microenvironment to activate repair processes and subsequently return to homeostasis. However, chronic inflammation induces permanent changes in cytokine production which exacerbate tissue damage and may even favor tumor development. Here, we address the contribution of post-transcriptional regulation, by the RNA-binding protein CPEB4, to intestinal immune homeostasis and its role in inflammatory bowel diseases (IBD) and colorectal cancer (CRC) development.

The First Use of Human-Derived ADM in Prepectoral Direct-to-Implant Breast Reconstruction after Skin-Reducing Mastectomy.

Introduction: Large and ptotic breasts always represented a great reconstructive challenge for plastic surgeons. In order to deal with these patients, we started performing Wise-pattern skin-reducing mastectomies (SRM) followed by direct-to-implant breast reconstructions (DTI-BR) in the prepectoral space where the implants were covered with the autologous adipo-dermal flap and a human acellular dermal matrix called MODA.

Materials And Method: We retrospectively reviewed all patients that underwent Wise-pattern SRM followed by MODA-assisted, prepectoral, DTI-BR between January 2017 and November 2019 at our Institution.

"Bifidus pedicle", The Use of Bilobed Superomedial Pedicle for Breast Reshaping Following Upper Outer Quadrantectomy: A New Oncoplastic Breast Surgery Technique.

Introduction: The aim of this work was to describe our technique, the "Bifidus pedicle", which is a modification of the superomedial pedicle, for managing large breast cancers (BCs) in the upper outer quadrant (UOQ) in patients with medium/large breasts and associated ptosis. Observed complications, cosmetic outcome and oncologic safety were also reported.

Materials And Methods: Thirty patients underwent our modification of the superomedial pedicle combined with a Wise skin resection pattern for large BCs in the UOQ.

A possible future for anaesthesia in breast surgery: thoracic paravertebral block and awake surgery. A prospective observational study.

Introduction: Quadrantectomy is a surgical procedure traditionally performed under general anaesthesia with intraoperative and postoperative opioid-based analgesia. The use of locoregional anaesthesia techniques in breast surgery has become widespread and allows excellent management of intraoperative and postoperative pain with reduced opioid consumption. We chose thoracic paravertebral block as regional anaesthesia technique in breast surgery to investigate the possibility of carrying out this surgery with the patient awake.

The Thyroid Hormone Inactivator Enzyme, Type 3 Deiodinase, Is Essential for Coordination of Keratinocyte Growth and Differentiation.

Thyroid hormones (THs) are key regulators of development, tissue differentiation, and maintenance of metabolic balance in virtually every cell of the body. Accordingly, severe alteration of TH action during fetal life leads to permanent deficits in humans. The skin is among the few adult tissues expressing the oncofetal protein type 3 deiodinase (D3), the TH inactivating enzyme.

Single shot ultrasound-guided thoracic paravertebral block for opioid-free radical mastectomy: a prospective observational study.

Background: General anesthesia (GA) is the most commonly used anesthesiological technique for radical mastectomy operations and can be associated with loco-regional anesthesia techniques. The aim of our study, carried out on 51 patients, was to assess the effectiveness of thoracic paravertebral block (TPVB) associated with GA, or as a sole anesthesiological technique for postoperative pain control and for the reduction of intra and postoperative opioids consumption.

Materials And Methods: Fifty-one patients with neoplastic breast disease and elected as candidates for radical mastectomy were included in the study.

Translational reprogramming in tumour cells can generate oncoselectivity in viral therapies.

Systemic treatment of cancer requires tumour-selective therapies that eliminate cancer cells yet preserve healthy tissues from undesired damage. Tumoral transformation is associated with profound effects in translational reprogramming of gene expression, such that tumour-specific translational regulation presents an attractive possibility for generating oncoselective therapies. We recently discovered that mRNA translational control by cytoplasmic polyadenylation element-binding proteins (CPEBs) is reactivated in cancer.

Fat grafting for breast cancer patients: From basic science to clinical studies.

Fat grafting in the surgical treatment of breast cancer has become popular in a short period of time because of the rising expectations of good esthetic results by the patients as well as the simplicity of the technique; however, the oncological safety for breast cancer patients remains a matter of debate. The procedure raises many questions considering that recent in-vitro studies have shown that fat grafting could promote tumor recurrence through diverse mechanisms, or even facilitate distant metastasis. We present a review of the currently available experimental and clinical data in order to describe and discuss patient selection criteria following breast cancer surgery.

Intracellular inactivation of thyroid hormone is a survival mechanism for muscle stem cell proliferation and lineage progression.

Precise control of the thyroid hormone (T3)-dependent transcriptional program is required by multiple cell systems, including muscle stem cells. Deciphering how this is achieved and how the T3 signal is controlled in stem cell niches is essentially unknown. We report that in response to proliferative stimuli such as acute skeletal muscle injury, type 3 deiodinase (D3), the thyroid hormone-inactivating enzyme, is induced in satellite cells where it reduces intracellular thyroid signaling.

The NOTA Study (Non Operative Treatment for Acute Appendicitis): prospective study on the efficacy and safety of antibiotics (amoxicillin and clavulanic acid) for treating patients with right lower quadrant abdominal pain and long-term follow-up of conservatively treated suspected appendicitis.

Objectives: To assess the safety and efficacy of antibiotics treatment for suspected acute uncomplicated appendicitis and to monitor the long term follow-up of non-operated patients.

Background: Right lower quadrant abdominal pain is a common cause of emergency department admission. The natural history of acute appendicitis nonoperatively treated with antibiotics remains unclear.

A proposed algorithm for multimodal liver trauma management from a surgical trauma audit in a western European trauma center.

Management of liver trauma is challenging and may vary widely given the heterogeneity of liver injuries' anatomical configuration, the hemodynamic status, the settings and resources available. Perhaps the use of non-operative management (NOM) may have potential drawbacks and the role of damage control surgery (DCS) and angioembolization represents a major evolving concept.1 Most severe liver trauma in polytrauma patients accounts for a significant morbidity and mortality.

An Intimate Relationship between Thyroid Hormone and Skin: Regulation of Gene Expression.

Skin is the largest organ of the human body and plays a key role in protecting the individual from external insults. The barrier function of the skin is performed primarily by the epidermis, a self-renewing stratified squamous epithelium composed of cells that undergo a well-characterized and finely tuned process of terminal differentiation. By binding to their receptors thyroid hormones (TH) regulate epidermal cell proliferation, differentiation, and homeostasis.

Epigenetic control of type 2 and 3 deiodinases in myogenesis: role of Lysine-specific Demethylase enzyme and FoxO3.

The proliferation and differentiation of muscle precursor cells require myogenic regulatory factors and chromatin modifiers whose concerted action dynamically regulates access to DNA and allows reprogramming of cells towards terminal differentiation. Type 2 deiodinase (D2), the thyroid hormone (TH)-activating enzyme, is sharply upregulated during myoblast differentiation, whereas type 3 deiodinase (D3), the TH-inactivating enzyme, is downregulated. The molecular determinants controlling synchronized D2 and D3 expression in muscle differentiation are completely unknown.

Identification and functional characterization of a novel mutation in the NKX2-1 gene: comparison with the data in the literature.

Background: NKX2-1 mutations have been described in several patients with primary congenital hypothyroidism, respiratory distress, and benign hereditary chorea, which are classical manifestations of the brain-thyroid-lung syndrome (BTLS).

Methods: The NKX2-1 gene was sequenced in the members of a Brazilian family with clinical features of BTLS, and a novel monoallelic mutation was identified in the affected patients. We introduced the mutation in an expression vector for the functional characterization by transfection experiments using both thyroidal and lung-specific promoters.

Deiodination in cancer growth: the role of type III deiodinase.

Thyroid hormone (TH) is a pleiotropic agent that has widespread biological functions, i.e., it controls cellular growth, tissue development and homeostasis and neoplastic transformation.
