Tobacco smoking and oxidative stress (OS) are both related to a wide spectrum of adverse age-related health outcomes, but their association is not yet well-established. We examined the associations of self-reported smoking indicators, serum cotinine levels and smoking-related DNA methylation biomarkers with two urinary proxy markers of OS, 8-isoprostane (8-iso) and 8-hydroxy-2'-deoxyguanosine (8-oxodG), in two independent subsets of older adults recruited in Germany (discovery set: n = 978, validation set: n = 531)...

PURPOSE: In the randomized G-PCNSL-SG-1 trial, the addition of whole brain radiotherapy (45 Gy) to high-dose methotrexate (HD-MTX)-based chemotherapy (early WBRT arm) did not prolong overall survival (OS) as compared to HD-MTX-based chemotherapy alone (no early WBRT arm) in primary CNS lymphoma (PCNSL) patients. To determine whether WBRT might lead to quality of life (QoL)-relevant late neurotoxicity, this trial prospectively monitored QoL. METHODS: QoL measurements were performed using the EORTC-QLQ-C30 and BN20 questionnaires and combined with repeated Mini Mental State Examinations (MMSE)...

NKG2D, an activating receptor expressed on CD8(+) T lymphocytes, serves as a co-stimulation molecule by engagement with its ligands MICA/B and ULBPs to trigger immune activation against tumors. Currently, the biological function and clinical significance of NKG2D in gastric cancer remains unexplored. The study aims to investigate the expression of NKG2D in gastric cancer in association with clinical prognosis and its biological function. Real-time PCR was used to analyze NKG2D expression in paired cancer and adjacent non-malignant tissues in 139 gastric cancer patients between 2007 and 2010 in Shanghai Cancer Center...

INTRODUCTION: Cytotoxic chemotherapy is the mainstay treatment for metastatic colorectal cancer (mCRC). Fluoropyrimidines, oxaliplatin, and irinotecan are the most active drugs; however, their optimal sequencing has not yet been established. Some evidence has shown that upfront treatment with 5-fluorouracil, oxaliplatin, and irinotecan (FOLFOXIRI regimen) can improve outcomes for patients with mCRC. MATERIALS AND METHODS: We performed a systematic search in electronic databases...

Hepatic arterial infusion chemotherapy (HAIC) is a treatment used for liver metastases (LM) of colorectal cancer (CRC). Because of its technical conditions, it has been used in only a few experienced centers in France. Our aim was to evaluate its feasibility, efficacy and tolerance in 4 centers. Clinical, biological, and radiological data of patients treated with HAIC for unresectable LM from CRC in 4 institutions from October 2011 to January 2016 were retrospectively analyzed. Sixty-one patients with unresectable LM from CRC were included...

BACKGROUND AND PURPOSE: Radiotherapy (RT) to the primary nasopharyngeal tumor is frequently offered to patients with metastatic nasopharyngeal carcinoma (mNPC). However, only limited data exist to support RT in this setting. We used the National Cancer Database (NCDB) to evaluate outcomes for mNPC patients receiving chemotherapy with and without local RT. METHODS: The NCDB was queried for patients with mNPC with synchronous metastatic disease at diagnosis who received chemotherapy...

BACKGROUND: Current guidelines recommend adjuvant chemotherapy for resected pancreatic adenocarcinoma (PDAC). However, no studies have addressed its survival benefit for stage I patients as they comprise <10% of PDAC. METHODS: Using the NCDB 2006-2012, resected PDAC patients with stage I disease who received adjuvant therapy (chemotherapy or chemoradiation) were analyzed. Factors associated with overall survival (OS) were identified. RESULTS: 3909 patients with resected stage IA or IB PDAC were identified...

BACKGROUND: We evaluated the clinical significance of the presence of a ground glass opacity (GGO) component in clinical stage IA radiologic invasive non-small cell lung cancer (NSCLC). METHODS: We reviewed 497 surgically resected clinical stage IA radiologic invasive NSCLCs, which were then classified into two groups based on consolidation tumor ratio (CTR), that is part-solid (0.5 ≤ CTR < 1.0, n = 177) and pure-solid (CTR = 1.0, n = 320). The part-solid tumors were subdivided into GGO-predominant (0...

BACKGROUND: The prognostic nutritional index (PNI), calculated as 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (cells/mm(3)), can reportedly predict postoperative complications and prognosis for various types of malignancy. However, the clinical significance and prognostic value of the PNI for both short- and long-term outcomes remains uncertain in patients with lung cancer. METHODS: We retrospectively reviewed 248 patients with completely resected non-small cell lung cancer (NSCLC)...

The low-energy wing of the C∼B21←X∼(1)A1 absorption spectra for SO2 in the ultraviolet region is computed for the 32S,(33)S,(34)S and (36)S isotopes, using the recently developed ab initio potential energy surfaces (PESs) of the two electronic states and the corresponding transition dipole surface. The state-resolved absorption spectra from various ro-vibrational states of SO2(X∼(1)A1) are computed. When contributions of these excited ro-vibrational states are included, the thermally averaged spectra are broadened but maintain their key characters...

For high-risk low-grade gliomas (LGGs), adjuvant radiotherapy (RT) with procarbazine/lomustine/vincristine (PCV) chemotherapy increases overall survival (OS) over RT alone. However, in practice, temozolomide (TMZ) is often used instead of PCV. Using the National Cancer Data Base (NCDB), we provide the first investigation of practice patterns and outcomes of chemoradiotherapy with single-agent chemotherapy (SAC, analogous to TMZ) or multi-agent chemotherapy (MAC, analogous to PCV) for LGG. Patients with high-risk Grade II LGGs were queried in the NCDB...

Primary CNS lymphoma (PCNSL) is chemosensitive to high-dose methotrexate-based chemotherapy. However, responses in the elderly are short-lasting and outcome is poor. Given that radiotherapy and intensive chemotherapy expose elderly to severe toxicities, alternative consolidation approaches need to be evaluated. In this multicenter study, we retrospectively analyzed consecutive patients with newly-diagnosed PCNSL, aged >60, treated with a (R)-MPV-AAA regimen. The regimen consisted of three 28-day cycles of methotrexate (3...

Cancer is a leading cause of mortality in the world, with osteosarcoma being one of the most common types among children between 1 and 14 years old. Current treatments including preoperative chemotherapy, surgery and postoperative chemotherapy produce several side effects with limited effectiveness. The use of lipid nanoparticles as biodegradable shells for controlled drug delivery shows promise as a more effective and targeted tumor treatment. However, in vitro validation of these vehicles is limited due to fluid stagnation in current techniques, in which nanoparticles sediment onto the bottom of the wells killing the cells by asphyxiation...

BACKGROUND: In colon cancer, T4 stage is still assumed to be a relative contraindication for laparoscopic surgery considering the oncological safety. The aim of this systematic review with meta-analysis was to evaluate short- and long-term oncological outcomes after laparoscopic surgery for T4 colon cancer, and to compare these with open surgery. METHODS: Using systematic review of literature, studies reporting on radicality of resection, disease-free survival (DFS), and/or overall survival (OS) after laparoscopic surgery for T4 colon cancer were identified, with or without a control group of open surgery...

The effects of laparoscopic liver resection (LLR) and open liver resection (OLR) on oncological outcomes for colorectal cancer liver metastases (CCLM) remain inconclusive. Major databases were searched from January 1992 to October 2016. Effects of LLR vs OLR were determined. The primary endpoints were oncological outcomes. In total, 32 eligible non-randomized studies with 4697 patients (LLR: 1809, OLR: 2888) were analyzed. There were higher rates of clear surgical margins (OR: 1.64, 95%CI: 1.32 to 2.05, p < 0...

It has been reported that younger patients with non-small cell lung cancer (NSCLC) tend to have a better prognosis. Yet, few studies have focused on the clinicopathological characteristics and prognosis of young small cell lung cancer (SCLC), especially for patients with age < 50. In our study, we used Surveillance, Epidemiology, and End Results (SEER) population-based data and identified 16503 patients with SCLC including 711 patients aged < 50, 3338 patients aged 50-59, 5937 patients aged 60-69, 4649 patients aged 70-79 and 1868 patients aged ≥ 80 between 2010 and 2013...

Here we present a parallel study of mRNA and microRNA expression during oral siphon (OS) regeneration in Ciona robusta, and the derived network of their interactions. In the process of identifying 248 mRNAs and 15 microRNAs as differentially expressed (DE), we also identified 57 novel microRNAs, several of which are among the most highly DE. Analysis of functional categories identified enriched transcripts related to stress responses and apoptosis at the wound healing stage, signaling pathways including Wnt and TGF-β during early regrowth, and negative regulation of extracellular proteases in late stage regeneration...
