Objective: Neoadjuvant concurrent chemoradiotherapy (CCRT) is an increasingly common therapeutic strategy for locally advanced rectal cancer, but stratification of risk and final outcomes remain a major challenge. Transcobalamin 1 (TCN1), a vitamin B12 (cobalamin)-binding protein, regulates cobalamin homeostasis. High expression of TCN1 have been reported in neoplasms such as breast cancer and hepatocellular carcinoma. However, little is known about the relevance of TCN1 to rectal cancer receiving CCRT. This study examined the predictive and prognostic impact of TCN1 expression in patients with rectal cancer following neoadjuvant CCRT...

Purpose: Novel partners for established immune checkpoint inhibitors in the treatment of cancer are needed to address the problems of primary and acquired resistance. The efficacy of combination RANKL and CTLA4 blockade in anti-tumor immunity has been suggested by recent case reports in melanoma. Here we provide a rationale for this combination in mouse models of cancer. <br />Experimental Design: The efficacy and mechanism of a combination of RANKL and CTLA4 blockade was examined by tumor infiltrating lymphocyte analysis, tumor growth and metastasis using a variety of neutralizing antibodies and gene-targeted mice...

TGF-β1-induced epithelial-mesenchymal transition (EMT) has been proved to be associated with metastasis of breast cancer cells. We attempted to detect a novel mechanism that microRNAs mediated the TGF-β1-induced EMT in the process of breast cancer metastasis. Here we reported that the expression of miR-23a was higher in breast cancer cells with high metastasis ability and patients with lymph node metastasis and the treatment of TGF-β1 significantly upregulated the expression of miR-23a in breast cancer cells...

Background : Colorectal cancer is the third most common cancer in both sex worldwide and it is also the fourth most common cause of cancer mortality. For rectal cancer, neoadjuvant concurrent chemoradiotherapy (CCRT) followed by radical proctectomy is gold standard treatment for patients with stage II/III rectal cancer. By data mining a documented database of rectal cancer transcriptome (GSE35452) from Gene Expression Omnibus, National Center of Biotechnology Information, we recognized that ALDOB was the most significantly up-regulated transcript among those related to glycolysis (GO: 0006096)...

Peri-operative chemotherapy has been proposed to improve the survival of patients with colorectal cancer hepatic metastases (CRCHM). However, the role of the adjuvant chemotherapy post-metastasectomy for CRCHM patients who have undergone pre-operative chemotherapy is still undetermined. We retrospectively analyzed the role of adjuvant chemotherapy post-metastasectomy on relapse-free survival (RFS) and overall survival (OS) in 163 CRCHM patients who received pre-operative chemotherapy using a Kaplan-Meier curve and univariate/multiple Cox model...

Isoprenylcysteine carboxylmethyltransferase (ICMT) catalyzes the post-translational modification of RAB GTPases that contain C-terminal CXC motifs. However, the functional impact of this modification on RAB proteins has not been actively explored. We found that inhibition of ICMT significantly reduced cell migration in vitro and cancer invasion and metastasis in vivo. This role of ICMT was found to be mediated by RAB4A, an essential regulator of the fast recycling of integrin β3. Integrin β3 regulates cell polarity and migration when localized appropriately to the plasma membrane, thereby having an essential role in cancer metastasis...

AIM: Gastrointestinal stromal tumors (GIST) are quite rare tumors, but yet they are the most common mesenchymal lesions of gastrointestinal tract. Their outmost frequent origin site is stomach and presently surgical resection is the mainstay in the treatment of gastric non metastatic GIST. Their peculiar characteristic of growth and poor metastatic tendency make this tumors particularly prone to be managed by minimally invasive technique. Presenting our experience we want show the feasibility and safeness of laparoscopic approach for gastric GIST and its benefits versus traditional open surgery and pointing out short term and long terms outcomes...

Kasabach-Merritt syndrome (KMS) is a rare type of vascular tumor associated with a severely decreased platelet count. No standard guidelines for the treatment of the disease have been established so far. In the present study, a 1-year-old pediatric patient with KMS arising from tufted angioma was successfully and variously treated with steroids, vincristine, surgery and propranolol for 18 months. Systemic steroids stabilized the platelet count stable, while vincristine reduced the size of the tumor. Due to unpredictable response, the patient was operated...

Pituitary carcinomas are defined as pituitary tumors with craniospinal and/or systemic metastasis. These are rare and highly aggressive lesions. We present an unusual case of a 52-year-old male who had a pituitary adenoma removed via craniotomy. The tumor recurred three years post-op near the surgical tract, and slowly enlarged before removal two years later. Technically, this lesion was defined as a pituitary carcinoma, even though the histology and clinical course were atypical. There is no standardized grading system for pituitary tumors and ideal criteria should correlate clinically...

The bone is one of the most common sites of metastasis in patients with cancer. Current treatments for bone metastases include bisphosphonates, denosumab, non-steroidal anti-inflammatory drugs and analgesics, but each of them has certain limitations. Cytokines and mediators released from various cells in the bone microenvironment may drive a vicious cycle of osteolytic bone metastases. Iguratimod (T-614), a novel disease-modifying anti-rheumatic drug, has demonstrated therapeutic effects by suppressing the production of inflammatory cytokines in rats and patients with rheumatoid arthritis...
