BACKGROUND: Epidermodysplasia verruciformis (EV) is a genodermatosis leading to infections with cutaneous HPV, persistent plane warts and a high rate of non-melanoma skin cancer (NMSC). Biallelic loss-of-function mutations in TMC6 and TMC8 are known to be causative. OBJECTIVE: The aim of this study was to report EV-causing mutations in four patients with EV and to give an overview of all described EV patients. PATIENTS AND METHODS: We investigated four patients with classical features of EV from two families...

BACKGROUND: Salvage radiotherapy (SRT) after radical prostatectomy (RPE) and lymphadenectomy (LAE) is the appropriate radiotherapy option for patients with persistent/ recurrent prostate cancer (PC). (68)Ga-PSMA-PET imaging has been shown to accurately detect PC lesions in a primary setting as well as for local recurrence or for lymph node (LN) metastases. OBJECTIVE: In this study we evaluated the patterns of recurrence after RPE in patients with PC, putting a highlight on the differentiation between sites that would have been covered by a standard radiation therapy (RT) field in consensus after the RTOG consensus and others that would have not...

Because no effective methods for preventing or screening for ovarian cancer exist, symptom recognition is integral to its early detection. The Centers for Disease Control and Prevention's Inside Knowledge: Get the Facts about Gynecologic Cancer campaign was developed to raise awareness and educate women and providers about risk factors, symptoms, recommended screening, and prevention strategies for the five main gynecologic cancers, including ovarian cancer. Inside Knowledge campaign materials were utilized by CDC's National Comprehensive Cancer Control Program grantees to educate women and providers about gynecologic cancer from 2014 to 2015...

There are unaesthetic aspects in teaching people about the early detection of colorectal cancer using the fecal immunochemical test. Comics were seen as a way to overcome those unaesthetic aspects. This study used the Asian grocery store-based cancer education venue to pilot-test the clarity, cultural acceptability, and alignment of five colorectal cancer education comics intended for publication in Asian American and Pacific Islander (API) community newspapers. After developing the colorectal cancer education comics, API students asked shoppers to review a comic from their collection and provide feedback on how to make the comic clearer and more culturally pertinent to API readers...

It has been reported that long non-coding RNA PANDA was disregulated in varieties types of tumor, but its expression level and biological role in hepatocellular carcinoma (HCC) remains contradictory. We detected PANDA expression in two independent cohorts (48 HCC patients following liver transplantation and 84 HCC patients following liver resection), and found that PANDA was down-regulated in HCC. Thereafter we explored its function in cancer biology by inversing its low expression. Surprisingly, overexpression of PANDA promoted HCC proliferation and carcinogenesis in vitro and in vivo...

P38 MAP kinase-dependent EGF receptor (EGFR) endocytosis is induced by stress. Ligand and stresses like X-rays, reportedly promote nuclear traffic of endocytosed EGFR for regulation of gene transcription and DNA repair. We fail to detect EGFR endocytosis or nuclear transport following X-ray treatment of HeLa or head and neck cancer cells, despite extensive DNA damage induction. Apparent nuclear staining with EGFR extracellular domain antibody remained present despite reduced/absent EGFR expression and so did not represent nuclear EGFR...

(68)Ga-PSMA PET/CT scanning has been shown to be more sensitive than conventional imaging techniques in patients with prostate cancer. This prospective Australian multicenter study assessed whether (68)Ga-PSMA PET/CT imaging impacts on management intent in patients with primary or recurrent prostate cancer. Methods: Prior to undertaking (68)Ga-PSMA PET imaging, referring medical specialists completed a questionnaire detailing relevant demographic and clinical data as well as their proposed management plan. A separate follow up questionnaire was completed after the (68)Ga-PSMA PET/CT scan results were available to determine whether their management plan would change...

Purpose:  The majority of genomic alterations causing intratumoral heterogeneity (ITH) in colorectal cancer (CRC) are thought to arise during early stages of carcinogenesis as a burst but only after truncal mutations in APC have expanded a single founder clone. We have investigated if the initial source of ITH is consequent to multiple independent lineages derived from different crypts harboring distinct truncal APC and driver KRAS mutations, thus challenging the prevailing monoclonal monocryptal model. <p>Experimental design: High-depth next-generation sequencing and SNP arrays were performed in whole lesion extracts of 37 FAP colorectal adenomas...

BACKGROUND: The bone represents one of the most common sites of metastases in breast cancer. The aim of the current study was to evaluate the diagnostic potential of several circulating markers to detect metastasis to bones in patients with breast cancer. PATIENTS AND METHODS: Receptor activator of Nuclear Factor-kappa β (NF-Kβ) ligand (RANKL), osteoprotegrin (OPG), vitamin D (VIT D), Chitinase-3-like protein 1; also known as YKL-40, topoisomerase IIα (TOPO2a), and human epidermal growth factor receptor 2 (HER2) were measured in blood samples obtained from 122 patients with breast cancer and 25 healthy controls...

BACKGROUND: In standard pre-analytical conditions, an isolation step is required for circulating tumor DNA (ctDNA) analysis. The need for this step remains unclear with the development of ultrasensitive detection technologies such as digital PCR (dPCR). The aim of our study was to evaluate the ctDNA detection by dPCR platform either directly from plasma (plasma group, PG) or after an isolation step (isolation group, IG). METHODS: We included 17 patients corresponding to a selection of 43 blood samples in metastatic colorectal cancer patients...

Drug resistance is one of the major cause of pancreatic cancer treatment failure. Thus, it is still imperative to develop new active compounds and novel approach to improve drug efficacy. Here we present 9-amino-1-nitroacridine antitumor agent, C-1748, developed in our laboratory, as a candidate for pancreatic cancer treatment. We examined (i) the cellular response of pancreatic cancer cell lines: Panc-1, MiaPaCa-2, BxPC-3 and AsPC-1, differing in expression levels of commonly mutated genes for this cancer type, to C-1748 treatment and (ii) the role of P450 3A4 isoenzyme and cytochrome P450 reductase (CPR) in the modulation of this response...

INTRODUCTION: Venous thromboembolism (VTE) represents a serious complication after oncologic surgery. Recent studies have shown that the risk of VTE persists several weeks after surgery. This study assesses the form of presentation and time course of VTE after abdominal and pelvic cancer surgery. METHODS: Prospective, multicenter, observational study that analyzes data from an international registry (RIETE) that includes consecutive patients with symptomatic VTE...

BACKGROUND: Ovarian tissue cryopreservation is a technique for fertility preservation addressed to prepubertal girls or to patients for whom no ovarian stimulation is possible before initiation of gonadotoxic treatments. Autotransplantation of frozen-thawed ovarian tissue is the only available option for reuse but presents some limitations: ischemic tissue damages post-transplant and reintroduction of malignant cells in cases of cancer. It is therefore essential to qualify ovarian tissue before autograft on a functional and oncological point of view...

BACKGROUND: As cancer metastasis is the deadliest aspect of cancer, causing 90% of human deaths, evaluating the molecular mechanisms underlying this process is the major interest to those in the drug development field. Both therapeutic target identification and proof-of-concept experimentation in anti-cancer drug development require appropriate animal models, such as xenograft tumor transplantation in transgenic and knockout mice. In the progression of cancer metastasis, circulating tumor cells (CTCs) are the most critical factor in determining the prognosis of cancer patients...

Acute abdomen secondary to epithelial ovarian cancer rupture during pregnancy is a rare event. Our aim is to present how the work of a coordinated multidisciplinary team in a case of ruptured epithelial ovarian cancer during pregnancy is feasible to obtain the best results possible. A 34-year-old woman during the 37th week of her first gestation presented with an acute abdomen. During laparotomy, a ruptured 16.5-cm left ovarian tumor was detected; the tumor was extirpated and sent to pathologic evaluation. In the meantime, a Kerr cesarean section was performed, and a healthy female neonate was born...

Squamous cell carcinoma (SCC) is the sixth most frequent malignant tumor of the head and neck region. Despite advances in therapeutic options over the last decades, the rate of mortality and morbidity has not been improved markedly. A small subset of cells, cancer stem cells (CSCs), with self-renewal properties have become a major focus of current cancer research. CD44 and p63 are identified as candidate stem cell markers in normal squamous epithelium and SCC. The role of these markers in oral squamous cell carcinoma (OSCC) is still debatable...

Current methods for identifying neoplastic cells and discerning them from their normal counterparts are often nonspecific and biologically perturbing. Here, we show that single-cell micro-Raman spectroscopy can be used to discriminate between resistant and sensitive multiple myeloma cell lines based on their highly reproducible biomolecular spectral signatures. In order to demonstrate robustness of the proposed approach, we used two different cell lines of multiple myeloma, namely MM.1S and U266B1, and their counterparts MM...

INTRODUCTION: The conservative surgery is more and more indicated for breast cancer. However, we still fear local recurrence which is mostly due to residual tumors?. Several techniques have been used to minimize theses residual tumors; one of them is the systematic circumferential tumor cavity shaving (SCTCS). METHODS: We sampled 75 female patients who had conservative surgery with positive shaved margins in the anatomopathology examination and to whom a complementary treatment with mastectomy have been decided...
