The sentinel lymph node (SLN) is defined as the first regional lymph node to receive lymphatic drainage from a malignant tumor. Therefore, this node is a "sentinel" for second metastatic lymph node stations and for labeling regional tumor spread. For SLN detection, many surgeons preferred a combination of a preoperative injection of radiolabeled colloid and the intraoperative injection of blue dye. Under this combination protocol, nodes are considered to be "sentinel nodes" if they are radioactive and blue...

The secreted semaphorin Sema3E controls cell migration and invasiveness in cancer cells. Sema3E-receptor, PlexinD1, is frequently upregulated in melanoma, breast, colon, ovarian and prostate cancers; however, the mechanisms underlying PlexinD1 upregulation and the downstream events elicited in tumor cells are still unclear. Here we show that the canonical RBPjk-dependent Notch signaling cascade controls PlexinD1 expression in primary endothelial and cancer cells. Transcriptional activation was studied by quantitative PCR and promoter activity reporter assays...

BACKGROUND: Several cellular functions relate to ion-channels activity. Physiologically relevant chains of events leading to angiogenesis, cell cycle and different forms of cell death, require transmembrane voltage control. We hypothesized that the unordered angiogenesis occurring in solid cancers and vascular malformations might associate, at least in part, to ion-transport alteration. METHODS: The expression level of several ion-channels was analyzed in human solid tumor biopsies...

Kindlins are a small family of 4.1-ezrin-radixin-moesin (FERM)-containing cytoplasmic proteins. Kindlin-3 is expressed in platelets, hematopoietic cells, and endothelial cells. Kindlin-3 promotes integrin activation, clustering and outside-in signaling. Aberrant expression of kindlin-3 was reported in melanoma and breast cancer. Intriguingly, kindlin-3 has been reported to either positively or negatively regulate cancer cell metastasis. In this study, we sought to clarify the expression of kindlin-3 in melanoma cells and its role in melanoma metastasis...

Positron emission tomography (PET) imaging has transformed diagnostic nuclear medicine and become an essential strategy in cancer management. With the expected growth of this molecular imaging modality, there is a recognized need for new PET probes to address the clinical challenges in the early diagnosis and staging of various types of cancers. In this endeavor, the prospect of using 64Cu in the form of simple Cu2+ ions as PET probe is not only a cost-effective proposition, but also seems poised to broaden the palette of molecular imaging probes in the foreseeable future...

As new and effective novel therapies in inflammatory bowel disease (IBD) become available, patients are living longer with advancing age and are at increased risk for malignancy. The management of IBD and malignancy involves multiple combinations of chemotherapy agents and IBD drugs, with the potential for interactions between these therapies. Interactions may either potentiate the effectiveness of drug class or exacerbate their common side effects. In this review article, we present a guide on studied interactions between IBD therapies and chemotherapy agents, specifically those of colorectal cancer, breast cancer, non-Hodgkin's lymphoma, and melanoma...

The radio guided occult lesion localization (ROLL) technique has been in use since the mid-90's, mainly in breast surgery. It is nowadays used for many oncological pathologies such as parathyroid lesions, melanoma, and colorectal tumors. We present the case of a patient with an 11 mm left meso rectal solitary recurrence of a primary ovarian cancer in whom the ROLL technique was used to identify the implant. The radio isotope was introduced with a 22g needle with Endoscopic ultrasound technique using an Echo lineal endoscope...

Glycosylation is the most complex post-translational modification of proteins. Altered glycans on the tumor- and host-cell surface and in the tumor microenvironment have been identified to mediate critical events in cancer pathogenesis and progression. Tumor-associated glycan changes comprise increased branching of N-glycans, higher density of O-glycans, generation of truncated versions of normal counterparts, and generation of unusual forms of terminal structures arising from sialylation and fucosylation. The functional role of tumor-associated glycans (Tn, sTn, T, and sLe(a/x)) is dependent on the interaction with lectins...

Cowden Syndrome (CS) is an uncommon autosomal dominant multiorgan/system genodermatosis. It is characterized by the development of multiple hamartomas of endodermal, mesodermal and ectodermal origin, an increased lifetime risk of breast, thyroid, endometrial, and other cancers and an identifiable germline mutation. Mucocutaneous hamartomas are the most common lesions seen and mainly include facial trichilemmomas, oral mucosal papillomas, and benign acral keratoses. Herein, we report a case of a 63-year-old Caucasian male with a long-established diagnosis of CS and history of thyroid cancer, colonic polyps, and innumerable trichilemmomas, seborrheic keratoses, squamous papillomas, and non-melanoma skin cancers excised in the past...

Honokiol (C18H18O2) is a biphenolic natural product isolated from the bark and leaves of Magnolia plant spp. During the last decade or more, honokiol has been extensively studied for its beneficial effect against several diseases. Investigations have demonstrated that honokiol possesses anti-carcinogenic, anti-inflammatory, anti-oxidative, anti-angiogenic as well as inhibitory effect on malignant transformation of papillomas to carcinomas in vitro and in vivo animal models without any appreciable toxicity. Honokiol affects multiple signaling pathways, molecular and cellular targets including nuclear factor-κB (NF-κB), STAT3, epidermal growth factor receptor (EGFR), cell survival signaling, cell cycle, cyclooxygenase and other inflammatory mediators, etc...

The movement toward precision medicine with targeted therapeutics for cancer treatment has been hindered by both innate and acquired resistance. Understanding the molecular wiring and plasticity of oncogenic signaling networks is essential to the development of therapeutic strategies to avoid or overcome resistance. The mechanistic target of rapamycin (mTOR) complex 1 (mTORC1) represents a highly integrated signaling node that is dysregulated in the majority of human cancers. Several studies have revealed that sustained mTORC1 inhibition is essential to avoid resistance to targeted therapeutics against the driving oncogenic pathway in a given cancer...

OBJECTIVE: Brain metastases occur between 10 and 40% of patients with cancer and are more common than primary brain tumors (30-40%) and their incidence is growing because of the improvements in control of systemic disease, the prolonged survival and the better radiological detection. Modern treatment of brain metastases dramatically changed their expected prognosis that traditionally has been considered very poor referring such patients only to palliation because their terminal stage, and new prognostic indexes have been proposed to evaluate them...

Cutaneous squamous cell carcinoma is the second common cutaneous cancer, especially in the elderly. Sentinel lymph node biopsy is generally performed in breast cancers and cutaneous melanomas to detect occult nodal metastases. The benefit of sentinel lymph node biopsy in improving cutaneous squamous cell carcinoma prognosis is doubtful. One hundred and sixty-nine patients who underwent treatment for cutaneous squamous cell carcinoma between 2004 and 2015, and who were followed up for at least 6 months or developed metastases within the follow-up period were included...
