Platinum/5-fluorouracil (PF) is commonly used for chemoradiotherapy (CRT) for locally advanced esophageal and esophagogastric junction (EGJ) cancers. Weekly carboplatin and paclitaxel (CP) regimen for preoperative CRT has increased in popularity due to its potentially less toxicity. We retrospectively compared the tolerability and efficacy of these regimens. Patients with esophageal and EGJ squamous cell carcinoma (SCC) or adenocarcinoma who received CRT with curative intent were included. Safety and tolerability during CRT were evaluated using the CTCAE version 4...

Tumor biomarkers such as hormone receptors, HER-2 and Ki-67 are used routinely in clinical practice for classification of molecular subtypes of breast cancer. Cell proliferation evaluated by Ki-67 antigen expression is important to determine tumor aggressiveness. However, there is a paucity of studies comparing Ki-67 expression in an expressive number of cells among molecular subtypes of breast cancer, particularly among less and more aggressive tumors, such as luminal A and triple-negative, which have led us to the present study...

Research on the long-term effects of complementary and integrative medicine (CIM) is limited. In this study, we explore the impact of a CIM intervention on gastro-intestinal (GI)-related concerns in patients with breast/gynecological cancer undergoing chemotherapy. Patients reporting chemotherapy-related GI concerns were referred by their cancer care providers to a CIM consultation and treatments and assessed at baseline and at 12 weeks. The following tools were used: Edmonton Symptom Assessment Scale (ESAS), Measure Yourself Concerns and Wellbeing (MYCAW) and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)...

Management of human epidermal growth factor receptor-2-positive (HER2+) breast cancer patients includes the combination of adjuvant chemotherapy and trastuzumab. A meta-analysis reported that <5% of HER2+ breast cancer patients will develop trastuzumab-induced cardiotoxicity (TIC). Observational data suggest that incidence is much higher. We aimed to determine the incidence, time to development, and risk factors associated with TIC among less selected patients. A retrospective cohort study was carried out in 160 HER2+ breast cancer patients who received adjuvant chemotherapy with trastuzumab from January 2006 to June 2014 at St...

The aim of this study was to examine whether novel agents proteasome inhibitor bortezomib and immunomodulatory drugs lenalidomide and thalidomide are effective in prolonging overall survival (OS) for patients with newly diagnosed multiple myeloma (MM) in the real-world practice setting. A nationwide and population-based retrospective cohort of elderly patients with advanced newly diagnosed MM from 2000 to 2009 were identified from the Surveillance, Epidemiology, and End Results-Medicare linked data. Survival was compared between cases in 2005-2009 and in 2000-2004, and between patients treated with anti-MM therapy and the untreated among cases in 2005-2009, using Cox proportional hazards models, Kaplan-Meier methods, and propensity score adjustment to further control for baseline confounding...

Accelerated hypofractionated whole-breast radiotherapy (WBRT) is considered a standard therapeutic option for early breast cancer (EBC) in the postoperative setting after breast conservation (BCS). A boost to the lumpectomy cavity may further increase local control. We herein report on the 10-year results of a series of EBC patients treated after BCS with hypofractionated WBRT with a concomitant photon boost to the surgical bed over 4 weeks. Between 2005 and 2007, 178 EBC patients were treated with a basic course of radiotherapy consisting of 45 Gy to the whole breast in 20 fractions (2...

Ovarian cancer is often diagnosed at advanced stages, when poorly responsive to standard treatment. First-line treatment consists in schemes including cytoreductive surgery followed by adjuvant chemotherapy schemes with platinum and taxane derivatives. Second-line regimens are based on gemcitabine and liposomal doxorubicin. Third line is often not worthwhile because of the high toxicity with poor response to treatment. Previously, we showed that paclitaxel (PTX) carried in non-protein lipid core nanoparticles (LDE) resembling the chemical structure of LDL has remarkably reduced toxicity...

Cancer survivors often have poor outcomes compared to their peers without cancer. Mortality from prostate cancer has been steadily decreasing, and these cancer survivors have other comorbidities that progress over time. Current study explores the type of admissions and associated risk factors with recurrent hospitalizations among prostate cancer survivors. A retrospective review of medical records was performed at a single academic institution for male patients aged 40 years and older who were diagnosed with prostate cancer more than 2 years prior to the study's observation period from January 2008 to December 2010...

Previous research has identified disparities between urban and rural cancer care, including clinical trial access. Therefore, we addressed three different questions in patients with metastatic renal cell cancer managed according to national guidelines in a rural Norwegian standard practice setting. (1) How many patients would have been eligible for three recent landmark randomized clinical trials? (2) Is survival different between eligible and non-eligible patients receiving first-line systemic therapy? (3) Is survival different between eligible patients and published trial results? We performed a retrospective analysis of 101 consecutive patients (2006-2016)...

Human papillomavirus (HPV) infection is associated with several genetic alterations including oncogene amplification, leading to increased aggression of tumors. Recently, a relationship between HPV infection and oncogene amplification has been reported, but this finding remains controversial. This study therefore investigated relationships between HPV infection and amplification of genes in the epidermal growth factor receptor (EGFR) signaling cascade in oral squamous cell carcinoma (OSCC). Extracted DNA from 142 formalin-fixed paraffin-embedded (FFPE) OSCC tissues was performed to investigate the copy number of EGFR, KRAS, c-myc and cyclin D1 genes using real-time polymerase chain reaction (RT-PCR) and compared with calibrators...

High-dose capsaicin patch is effective in treatment of neuropathic pain in HIV-associated neuropathy and diabetic neuropathy. There are no studies assessing effectiveness of high-dose capsaicin patch in treatment of chemotherapy-induced peripheral neuropathy. We sought to determine the effectiveness of treatment of pain associated with chemotherapy-induced peripheral neuropathy with high-dose capsaicin patch. Our study group consisted of 18 patients with clinically confirmed oxaliplatin-induced neuropathy. Baseline characteristic including underling disease, received cumulative dose of neurotoxic agent, neuropathic symptoms, prior treatment and initial pain level were recorded...

Biomarkers for the prognosis of breast cancer have been routinely used in clinical practice, including the expression of hormone receptors, Ki-67 and HER-2. More recently, Bcl-2 has been recognized as an important prognostic factor in breast cancer, although controversies persist with respect to the significance of its expression. The aim of the present study was to evaluate Bcl-2 antigen expression in luminal A and triple-negative breast cancer. Sixty women with invasive ductal carcinoma were included in the study and divided into two groups: Group A (luminal A) and Group B (triple-negative), with 30 cases in each group...

It is unclear how treatment sequencing for metastatic castration-resistant prostate cancer (mCRPC) affects real-world patient outcomes. We assessed treatment sequences, patient characteristics and overall survival (OS) in post-docetaxel mCRPC patients. mCRPC patients receiving second-line cabazitaxel or androgen receptor-targeted therapy (ART; abiraterone/enzalutamide) post-docetaxel were identified using electronic medical records. OS was assessed from second-line therapy initiation using Cox regressions adjusting for: metastases; prostate-specific antigen (PSA); hemoglobin; alkaline phosphatase (ALP); albumin; second-line therapy initiation year...

As the overall survival of patients with lung cancer continues to increase, more cancer survivors are faced with the risk of developing treatment-related cardiovascular toxicities. The increased knowledge of the molecular biology of non-small cell lung cancer has led to new and more personalized treatments. Nevertheless, the usual chemotherapy schemes and radiation therapy induce cardiac toxicities that are frequently underappreciated or go unnoticed. Up to date, the majority of cardiotoxicity studies have been focused in breast cancer, but new treatments in lung cancer patients, such as immune checkpoint-blocking antibodies or tyrosine kinase inhibitors, may also exert these cardiac toxic effects and therefore demand of the close collaboration of oncologists and cardiologists, in order to be addressed...

Although DNA hypermethylation at non-promoter region of the Zygote arrest 1 (ZAR1) gene has been observed in many types of tumor, including neuroblastoma (NB), the role of this gene in tumor development and/or progression is unclear. One reason is that knowledge about the function of ZAR1 protein is limited. Although it has been reported that ZAR1 plays a crucial role in early embryogenesis and may act as a transcriptional repressor for some transcripts, the detailed mechanism is still elusive. In the present study, we analyzed public data of NB patients and found that higher expression levels of ZAR1 were significantly associated with a shorter survival period...

Aberrant DNA methylation of CpG islands occurred frequently in CRC and associated with transcriptional silencing of key genes. In this study, the CIMP combined with MLH1 or p16 (INK4a) methylation status was determined in CRC patients and correlated with clinicopathological parameters and overall survival. Our data showed that CIMP+ CRCs were identified in 32.9% of cases and that CACNAG1 is the most frequently methylated promoter. When we combined the CIMP with the MLH1 or the p16 (INK4a) methylation status, we found that CIMP-/MLH1-U (37...

MiR-181a-2 plays a major role in cell proliferation both positively and negatively depending on tissue type by targeting several regulators 3'UTR regions. We have predicted several targets for miR-181a-2 through computational approaches and characterized one its interesting target, CUL4A, an E3 ubiquitin ligase. CUL4A regulates diverse functions in the cells including DNA repair, DNA replication, cell cycle, genomic stability through polyubiquitination of target proteins. Deregulation of both miR-181a-2 and CUL4A are reported in many cancerous cells, but the functional link between them is unknown...

DNA methyltransferases make use of alternative splicing mechanism to generate various splice variants, but their role(s) in modulating DNA methylation patterns in the cells is unclear. Notably, DNMT3B alone contains nearly 40 different splice variants. In this study, we have identified a novel splice variant of DNMT3B, which lacks exon 7 and 10 from leukemic cell lines which we termed as DNMT3B9. The exon 7 codes for the major part of PWWP domain, and exon 10 inclusion serves as a pluripotent marker. By quantitative RT-PCR using exon-exon junction-specific primers, we showed higher level of DNMT3B9 transcripts in several leukemic cell lines...
