BACKGROUND: Malnutrition can adversely affect treatment responses and oncological outcomes in cancer patients. However, among patients with rectal cancer who undergo chemoradiotherapy (CRT), the significance of peri-treatment nutrition assessment as a predictor of treatment response and outcome remains unclear. OBJECTIVE: The aim of this study was to determine whether the Prognostic Nutrition Index (PNI) based on peri-treatment serum can be used as a predictor of treatment response and outcome in patients with rectal cancer who undergo CRT...

Interactions between tumor cells and fibroblasts play a pivotal role in cancer development and progression. Indeed, the paracrine communication between these two cell types is known to have physiological effects that alter carcinogenic and metastatic potential. An often overlooked player in these interactions is the involvement of the extracellular matrix (ECM). The network of ECM proteins secreted from fibroblasts is reportedly altered with cancer initiation and progression, and in several cases has been associated with patient outcome...

Current treatments of advanced prostate cancer only marginally increase overall survival and can be regarded as predominantly palliative. Hence, there is an urgent need for novel therapeutic strategies for the treatment of primary tumors and, more importantly perhaps, for the prevention of tumor progression and metastasis formation. Clinically relevant preclinical models are therefore urgently needed. An ideal, clinically relevant preclinical model would mimic the genetic and phenotypic changes that occur at the different stages of human prostate cancer progression and subsequent metastasis...

In this research, a novel method was used to successfully make Pluronic P123 stably coated on mesoporous silica nanoparticles (MSN). That P123 and MSN co-constructed a drug delivery system (DDS) had not been reported. In this DDS, the coating of P123 was realized through hydrophobic interaction with octadecyl chain modified MSN. Experiments found only Pluronic with an appropriate ratio of hydrophilic and lipophilic segment could keep the nanoassemblies stable.
 For comparison, nanoassemblies consisted of P123 and octadecyl chain modified MSN with or without disulfide bond were prepared, which were denoted as PSMSN and PMSN respectively...

Tumour invasion into the surrounding stroma is a critical step in metastasis, and it is necessary to clarify the role of microenvironmental factors in tumour invasion. We present a microfluidic system that simulated and controlled multi-factors of the tumour microenvironment for three-dimensional (3D) assessment of tumour invasion into the stroma. The simultaneous, precise and continuous arrangement of two 3D matrices was visualised to observe the migration of cancer cell populations or single cells by transfecting cells with a fluorescent protein...

The facultative anaerobe Salmonella strain VNP20009 selectively colonizes into tumors following systemic injection due to its preference for the hypoxia in the tumor cores. However, the Phase 1 Clinical Trial of VNP20009 has been terminated mainly due to its weak anti-tumor effects and exhibition of dose-dependent toxicity. Here we leveraged the advantages of VNP20009 biotherapy together with polydopamine-mediated photothermal therapy in order to enhance the antitumor efficacy toward malignant melanoma. VNP20009 was coated with polydopamine via oxidation and self-polymerization, which was then injected into tumor-bearing mice via the tail vein...

BACKGROUND: Prophylactic central compartment neck dissection (pCCND) in addition to total thyroidectomy (TT) includes removal of central compartment lymph nodes in the absence of clinical involvement on preoperative and intraoperative evaluation. The data regarding the influence of pCCND on oncologic outcomes and surgical complication rates is mixed and, therefore, is the focus of this analysis. METHODS: A systematic review of the literature on total thyroidectomy with prophylactic central compartment neck dissection (TT + pCCND) from January 1990 to October 2017 identified 221 abstracts of which 17 met inclusion criteria and were reviewed (1 randomized-control trial, 13 retrospective cohort studies, and 3 meta-analyses)...

Aberrant extra-vascular expression of VE-cadherin (VEC) has been observed in metastasis associated with vasculogenic mimicry (VM); however, the ultimate reason why non-endothelial VEC favors the acquisition of this phenotype is not established. In this study, we show that human malignant melanoma cells have a constitutively high expression of phoshoVEC (pVEC) at Y658; pVEC is a target of focal adhesion kinase (FAK) and forms a complex with p120-catenin and the transcriptional repressor kaiso in the nucleus...

Given that dysregulation of mechanics contributes to diseases ranging from cancer metastasis to lung disease, it is important to develop methods for screening the efficacy of drugs that target cellular forces. Here, nanoparticle-based tension sensors are used to quantify the mechanical response of individual cells upon drug treatment. As a proof-of-concept, the activity of bronchodilators is tested on human airway smooth muscle cells derived from seven donors, four of which are asthmatic. It is revealed that airway smooth muscle cells isolated from asthmatic donors exhibit greater traction forces compared to the control donors...

We describe a highly unusual case of metastatic melanoma in a 61-year-old female that manifested as a single groin lymph node metastasis accompanied by two distinct, subcutaneous sarcomatoid tumors on the same leg, without evidence of a primary tumor. Characterization encompassed extensive immunohistochemical staining as well as next-generation sequencing (NGS). The lymph node metastasis showed obvious features of melanoma. The two subcutaneous lesions, however, were morphologically and immunohistochemically consistent with high-grade myxofibrosarcoma and soft tissue mixed tumor, respectively...

BACKGROUND: Delta-shaped anastomosis is usually applied for an intracorporeal gastrogastrostomy in totally laparoscopic pylorus-preserving gastrectomy (TLPPG). However, the remnant stomach is slightly twisted around the anastomosis because it connects in side-to-side fashion. To realize an intracorporeal end-to-end gastrogastrostomy using an endoscopic linear stapler, we invented a novel method including a unique anastomotic technique. MATERIALS AND METHODS: In this new approach, we first made small gastrotomies at the greater and lesser curvatures of the transected antrum and then pierced it using an endoscopic linear stapler...

Primary liver cancer is a common kind of digestive cancers with high malignancy, causing 745,500 deaths each year. Hepatocellular carcinoma is the major pathological type of primary liver cancer. Traditional treatment methods for patients with hepatocellular carcinoma have shown poor efficacy in killing residual cancer cells for a long time. In recent years, tumor immunotherapy has emerged as a promising method owing to its safety and efficacy with respect to delaying the progression of advanced tumors and protecting postoperative patients against tumor relapse and metastasis...

We report a rare case of primary amelanotic malignant melanoma of the male urethra. A 65-year-old man with a urethral mass was referred to our hospital. A pathological diagnosis of a biopsy specimen revealed malignant melanoma. Thereafter, the patient underwent partial penectomy. The histopathological diagnosis was amelanotic malignant melanoma of the urethra. The patient had received DAV-Feron in an adjuvant setting; however, PET-CT revealed multiple metastasis. After receiving more than 10 cycles of nivolumab, the accumulation of FDG was no longer observed on PET-CT...
