OBJECTIVE: The role of sentinel lymph node (SLN) biopsy alone for staging of early-stage cervical cancer remains controversial. We aimed to determine the validity of this technique in women with early-stage cervical cancer. METHODS: We retrospectively reviewed women with early-stage cervical cancer who underwent SLN mapping followed by complete pelvic lymphadenectomy as part of initial surgical management from August 1997 through October 2015. All modes of surgical approach were included...

Metastatic cancer cells express Membrane Type 1-Matrix Metalloproteinase (MT1-MMP) to degrade the extracellular matrix in order to facilitate migration and proliferation. Tissue Inhibitor of Metalloproteinase (TIMP)-2 is the endogenous inhibitor of the MMP. Here, we describe a novel and highly effective fusion strategy to enhance the delivery of TIMP-2 to MT1-MMP. We can reveal that TIMP-2 fused to the haemopexin +/- transmembrane domains of MT1-MMP (two chimeras named T2PEX+TM and T2PEX) are able to interact with MT1-MMP on the cell surface as well as intracellularly...

OBJECT: In recent times, many published papers reported the diagnostic performance of CT, MRI, positron emission tomography (PET) using 2-[18F] fluoro-2-deoxy-D-glucose (FDG) and diffusion-weighted magnetic resonance imaging (DW-MRI) for detecting the lymph nodes (LNs) metastases in patients with cervical cancer. This study is aimed at assessing and comparing the diagnostic value of those non-invasive modalities in detecting the LNs metastases in cervical cancer patients. METHODS: Studies on the non-invasive modalities for the detection of metastatic LNs were searched in PubMed, Medline, Web of Science, Cochrane Library and Embase databases...

BACKGROUND: Nivolumab is an immune checkpoint inhibitor specific for the programmed death 1 (PD-1) receptor that has led to clinical responses in many cancer types. Identifying biomarkers predictive of response to PD-1 blockade is an area of active investigation. CASE PRESENTATION: We present a patient with recurrent, metastatic, PD-L1-negative small cell neuroendocrine carcinoma of the cervix (SCNEC) who experienced a complete response to nivolumab. Though nivolumab was discontinued over 4 months ago due to treatment-related adverse events, she continues to have no evidence of disease...

Cervical metastases from breast carcinoma are extremely rare after several years of disease-free survival. In this article, a metastatic tumor of the neck originating from a breast carcinoma, which has been treated 14 years ago, is discussed. A case is presented of a 48-year-old female patient with a history of breast carcinoma, which was surgically treated approximately 14 years ago. Patient was evaluated as glomus vagale because of clinical and radiologic characteristics. The resection of the mass was performed under general anesthesia, without any complications...

BACKGROUND: Oral squamous cell carcinoma (OSCC) is the most frequently occurring malignant tumour in the oral cavity. OSCC arises because of multiple genetic alterations. Cell cycle aberrations and aneuploidy are reportedly among the main characteristics of cancer cells and are associated with aggressive growth and poor prognosis. METHODS: The study sample included 47 non-metastasised (NM) and 39 metastasised (M) primary OSCC, with matched positive cervical lymph nodes (LN) and 17 normal oral mucosa (NOM) samples...

We report a case of minimal thyroid carcinoma diagnosed by a solitary pulmonary metastasis. A 70's man visited a medical practitioner because of chest discomfort, and there was an abnormality on the chest X-ray. Chest computed tomography(CT) showed a nodule in the right middle lobe of the lung. Positron emission tomography with 18-fluorodeoxyglucose(FDG)-PET revealed increased FDG uptake in that tumor, but did not reveal any other lesion. The tumor was clinically suspected to be a carcinoid tumor, primary lung cancer, metastatic lung cancer, or a benign tumor...

Radiotherapy remains the important therapeutic strategy for patients with esophageal cancer (EC). At present, there is no uniform opinion or standard care on the range of radiotherapy in the treatment of EC patients. This study aimed to investigate the risk factors associated with lower cervical lymph node metastasis (LNM) and to explore the distribution pattern of lower cervical metastatic lymph nodes. It could provide useful information regarding accurate target volume delineation for EC. We identified 239 patients who initial diagnosed with esophageal squamous cell carcinoma...

The tumor microenvironment is critical for metastasis to occur. Subcutaneous xenografts of tumors in immunodeficient mice are usually encapsulated and rarely metastasize as opposed to orthotopic tumors which metastasize if the original tumor was metastatic. In the present report, we were able to reconstitute a metastatic tumor microenvironment by subcutaneously co-transplanting a human cervical cancer cell line and human cervical cancer-associated fibroblasts (CAFs), in athymic mice, which resulted in lymph node metastasis in 40% of the animals...

Cancer of the uterine cervix (CACX) is one of the most common carcinoma affecting women worldwide. During treatment, histologically lymph node (LN) metastasis and presence of HPV DNA in blood plasma act as a major prognostic factor. Despite the lack of apparent LN involvement, some early-invasive CACX patients have shown recurrences and poor survival. This is suggestive of undetected early dissemination of cancer cells characterized by presence of HPV DNA in histologically non-metastatic LNs which finally progresses into histologically visible metastasis...

A new series of oxadiazoles were designed to act as inhibitors of the anti-apoptotic Bcl-2 protein. Virtual screening led to the discovery of new hits that interact with Bcl-2 at the BH3 binding pocket. Further study of the structure-activity relationship of the most active compound of the first series, compound 1, led to the discovery of a novel oxadiazole analogue, compound 16j, that was a more potent small molecule inhibitor of Bcl-2. 16j had good in vitro inhibitory activity with sub-micromolar IC50 values in a metastatic human breast cancer cell line (MDA-MB-231) and a human cervical cancer cell line (HeLa)...
