Importance: Population-level disease metrics are critical to guide the distribution of resources and implementation of public health initiatives. Internet search data reflect population interest in health topics and may be an alternative metric of disease characteristics when traditional sources are lacking, such as in basal and squamous cell carcinomas, which are not included in national cancer registries. However, these data are not yet well validated or understood. Objective: To evaluate whether state-specific normalized internet search volume correlates with incidence and mortality rates of common cancers in the United States, including melanoma...

Helicobacter pylori (H. pylori) is a Gram-negative and motile bacterium that colonizes the hostile microniche of the human stomach, then persists for the host's entire life, if not effectively treated. Clinically, H. pylori plays a causative role in the development of a wide spectrum of diseases including chronic active gastritis, peptic ulceration, gastric adenocarcinoma, and gastric mucosa-associated lymphoid tissue lymphoma. Due to the global distribution of H. pylori, it is no exaggeration to conclude that smart strategies are contributing to adaptation of the bacterium to its permanent host...

Anal intraepithelial neoplasia (AIN) is a premalignant lesion of the anal mucosa that is a precursor to anal cancer. Although anal cancer is relatively uncommon, rates of this malignancy are steadily rising in the United States, and among certain high risk populations the incidence of anal cancer may exceed that of colon cancer. Risk factors for AIN and anal cancer consist of clinical factors and behaviors that are associated with the acquisition and persistence of human papilloma virus (HPV) infection. The strongest HPV-associated risk factors are HIV infection, receptive anal intercourse, and high risk sexual behavior...

PURPOSE: Cetuximab and panitumumab are monoclonal antibody inhibitors that bind the epidermal growth factor receptor (EGFR) currently used in the treatment of metastatic colorectal cancer. The main adverse event related to EGFR inhibitors (EGFR-Is) is cutaneous toxicity, which can cause dosage reduction and interruption of treatment. State-of-the-art management of skin toxicity associated with EGFR-Is therapy involves the topical administration of corticosteroids and oral antibiotics, but is not completely effective in the management of toxicity...

Colon cancer is a leading cause of cancer related mortality. Until very recently the only existing options that medical oncologists had to treat metastatic colon cancer were a combination of chemotherapy, anti-EGFR and anti-angiogenic agents. We currently have the first proof that immune therapies could be an effective approach to battle colorectal cancers that carry a mismatch repair machinery deficient phenotype. It is expected that as our knowledge of the different mechanisms of immune-resistance grows, this therapeutic modality might soon be applicable to all patients...

Companion diagnostics (CoDx) will likely continue to rapidly increase in number and application to disease areas including solid tumors, for example EGFR for gefitinib and ALK fusion gene for crizotinib in non-small-cell lung cancer; KRAS against the use of cetuximab and panitumumab in colorectal cancer; HER2 for trastuzumab in breast cancer. CoDx are an indispensable part of personalized medicine and pharmacogenomics. In CoDx development, there are still many challenges, such as the business model promoting cooperation between diagnostics and pharmaceutical companies, and also the regulations related to CoDx...

Diabetic foot ulcers (DFUs) have a significant impact on patient quality of life. A prospective, descriptive pilot study was conducted between May 2012 and December 2013 through the dermatology outpatient unit in a Brazilian hospital to evaluate the clinical benefits of using Calendula officinalis hydroglycolic extract in the treatment of DFUs. Patients diagnosed with a stable neuropathic ulcer of >3 months' duration; ranging in size from 0.5-40 cm(2); without osteomyelitis, gangrene, bone exposure, cancer, or deep tissue infection; ages 18-90 years; with adequate glycemic control and no history of an allergy to C...

INTRODUCTION: Mechanical bowel obstruction in rectal cancer is a common problem, requiring stoma placement to decompress the colon and permit neo-adjuvant treatment. The majority of patients operated on in our hospital are referred; after stoma placement at the referring centre without overseeing final type of surgery. Stoma malpositioning and its effects on rectal cancer care are described. METHODS: All patients who underwent surgery for locally advanced or locally recurrent rectal cancer between 2000 and 2013 in our tertiary referral centre were reviewed and included if they received a stoma before curative surgery...

To establish the individualized treatment of patients with colorectal cancer, factors associated with chemotherapeutic effects should be identified. However, to the best of our knowledge, few studies are available on this topic, although it is known that the prognosis of patients and sensitivity to chemotherapy depend on the location of the tumor and that the tumor location is important for individualized treatment. In this study, primary tumors obtained from 1,129 patients with colorectal cancer were used to measure the mRNA expression levels of the following genes associated with the effects of standard chemotherapy for colorectal cancer: 5-fluorouracil (5-FU)-related thymidylate synthase (TYMS), dihydropyrimidine dehydrogenase (DPYD) and thymidine phosphorylase (TYMP); folate-related dihydrofolate reductase (DHFR), folylpolyglutamate synthase (FPGS) and gamma-glutamyl hydrolase (GGH); irinotecan-related topoisomerase I (TOP1); oxaliplatin-related excision repair cross-complementing 1 (ERCC1); biologic agent-related vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR)...

For many years, the question of whether hyperglycaemia, a manifestation of prediabetes, diabetes mellitus and metabolic syndrome, is a risk factor for colorectal cancer has been intensely studied. In fact, even after the conclusion of several prospective studies, the topic is still controversial. We conducted a systematic review and meta-analysis to investigate the dose-response relationship between blood glucose concentration and the incidence of colorectal cancer. A linear (P = 0.303 for non-linearity) dose-response relationship was observed between fasting plasma glucose (FPG) and colorectal cancer risk without significant heterogeneity...

The prognostic value of mast cells (MCs) in patients with liver metastases is a relatively new topic. The present study comparatively assessed tryptase-positive (MCT(+)) and CD117(+) MCs in liver metastases from various sites and correlated their expression with clinicopathological prognostic factors and survival. Our data pointed to differences in MCT and CD117 expression in liver metastases that seem to be related to the origin of the primary tumor. For colon cancer metastases, intra-tumor MCT(+) MCs were significantly correlated with tumor grade and nodal status, while peritumoral MCT(+) MCs and peritumoral CD117(+) MCs were significantly correlated with overall survival...

Ten years after the approval of bevacizumab in colorectal cancer patients, results from ML18147 and CORRECT studies have recently demonstrated the possibility to target angiogenesis in patients previously exposed to anti-VEGF. An increasing number of anti-angiogenic treatments are now available, however, no biomarker has yet succeeded in rationalizing our therapeutic strategies. Nevertheless, several lessons have been learned from preclinical and pivotal clinical studies. The first clinical trials demonstrated a survival benefit, adding VEGFA targeting monoclonal antibodies to chemotherapy in metastatic colorectal cancer patients (AVF2107, ECOG 3200)...
