INTRODUCTION: While radical cystectomy is the gold standard for muscle-invasive bladder cancer (MIBC), in octogenarians cystectomy results in a higher perioperative mortality rate (6.8-11.1%) than in younger patients (2.2%). Trimodality therapy is a bladder-sparing regimen composed of transurethral resection of bladder tumour (TURBT) and chemoradiotherapy, with intent for salvage cystectomy, and has a 62.5-90% initial complete response rate. In this study, we evaluate TURBT and chemoradiotherapy without salvage cystectomy in medically inoperable octogenarian patients...

The origins and spatial and temporal distributions of air pollutants (PM2.5, PM10, CO, SO2, NO2 and O3) during May to June of 2015 were investigated using data from 1490 monitoring sites in China. Aerosol number concentrations and meteorological data from Shijiazhuang, Nanjing, and Suzhou were combined with the MIX Asian emission data and the HYSPLIT model. Furthermore, the diurnal variation, size distribution, and main sources of air pollutants and aerosols were selectively characterized in the North China Plain (NCP) and the Yangtze River Delta (YRD)...

The design, synthesis and activity of polymodal compounds for the treatment of inflammatory bowel disease are reported. The compounds, being based on a metal-Schiff base motif, are designed to degrade during intestinal transit to release the bioactive components in the gut. The compounds have been developed sequential with the biomodal compounds combining copper or zinc with a salicylaldehyde adduct. These compounds were tested in a formalin induced colonic inflammation model in BK:A mice. From these studies a trimodal compound based on a zinc Schiff base analogue of sulfasalazine was designed...

Given the lack of randomized evidence comparing trimodal therapy (TMT) to radical cystectomy (RC) for muscle-invasive urothelial carcinoma of the bladder (UCB), we performed an observational cohort study to examine the comparative effectiveness of these two definitive treatments. Within the National Cancer Data Base (2004-2011),we identified 1257 (9.8%) and 11 586 (90.2%) patients who received TMT and RC, respectively. Inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier analysis showed that median overall survival (OS) was similar between the TMT (40 mo, 95% confidence interval [CI] 34-46) and RC groups (43 mo 95% CI 41-45; p=0...

Purpose Multidisciplinary management improves complex treatment decision making in cancer care, but its impact for bladder cancer (BC) has not been documented. Although radical cystectomy (RC) currently is viewed as the standard of care for muscle-invasive bladder cancer (MIBC), radiotherapy-based, bladder-sparing trimodal therapy (TMT) that combines transurethral resection of bladder tumor, chemotherapy for radiation sensitization, and external beam radiotherapy has emerged as a valid treatment option. In the absence of randomized studies, this study compared the oncologic outcomes between patients treated with RC or TMT by using a propensity score matched-cohort analysis...

In this work, we developed the surfactant-free aqueous synthesis of novel polyethylene glycol (PEG) coated Ba2GdF7:Yb(3+), Er(3+) upconversion nanoparticles (named as, Ba2GdF7:Yb(3+), Er(3+)@PEG UCNPs) for in vivo multimodality imaging including upconversion luminescence (UCL), X-ray computed tomography (CT), and T1-weighted magnetic resonance (MR). The as-prepared Ba2GdF7:Yb(3+), Er(3+)@PEG UCNPs not only present bright UCL and reasonably high CT/MR enhancements but also exhibit excellent colloidal stability, inappreciable cytotoxicity, and negligible organ toxicity...

Peripheral Artery Disease is a severe medical condition commonly characterized by critical or acute limb ischemia. Gradual accumulation of thrombotic plaques in peripheral arteries of the lower limb may lead to intermittent claudication or ischemia in muscle tissue. Ischemic muscle tissue with lesions may become infected, resulting in a non-healing wound. Stable progression of the non-healing wound associated with severe ischemia might lead to functional deterioration of the limb, which, depending on the severity, can result in amputation...

REVIEW
In-Jae Oh, Sung-Ja Ahn
Locally advanced non-small cell lung cancer (LA-NSCLC) is composed of heterogeneous subgroups that require a multidisciplinary team approach in order to ensure optimal therapy for each patient. Since 2010, the National Comprehensive Cancer Network has recommended chemoradiation therapy (CRT) for bulky mediastinal disease and surgical combination for those patients with single-station N2 involvement who respond to neoadjuvant therapy. According to lung cancer tumor boards, thoracic surgeons make a decision on the resectability of the tumor, if it is determined to be unresectable, concurrent CRT (CCRT) is considered the next choice...

Although radical cystectomy (RC) is considered as the standard therapy for muscle-invasive bladder cancer (MIBC), trimodal therapy (TMT) combining transurethral resection of the tumor with radiotherapy and chemotherapy is increasingly recommended as an alternative approach for bladder preservation. In the absence of randomized trials, we compared the clinical outcomes between RC and TMT using propensity score matching with 50 patients in the RC arm and 29 patients in the TMT arm. With respective median follow-up periods of 23 and 32 months for the RC and TMT groups, 5-year distant metastasis-free survival (58% vs...

REVIEW
Johannes R Kratz, Gavitt Woodard, David M Jablons
Superior sulcus tumors have posed a formidable therapeutic challenge since their original description by Pancoast and Tobias in the early twentieth century. Initial therapeutic efforts with radiotherapy were associated with high rates of relapse and mortality. Bimodality therapy with complete surgical resection in the 1960s paved the way for trimodality therapy as the current standard of care in the treatment of superior sulcus tumors. The evolution of treatment approaches over time has provided outcomes that come increasingly closer to rivaling those of similarly staged nonapical lung cancer...

INTRODUCTION: Higher target conformity and better sparing of organs at risk with modern radiotherapy (RT) may result in higher tumor control and less toxicities. In this study, we compare our institutional multimodality therapy experience of adjuvant chemotherapy and hemithoracic intensity-modulated pleural RT (IMPRINT) to previously used adjuvant conventional RT (CONV) in patients with malignant pleural mesothelioma (MPM) treated with lung-sparing pleurectomy/decortication (P/D). METHODS: We analyzed 209 patients who underwent P/D and adjuvant RT (n[CONV]=131, n[IMPRINT]=78) for MPM between 1974 and 2015...

Recent years have witnessed a number of clinical trials in Stage IIIA non-small cell lung cancer (NSCLC) comparing (A) induction chemotherapy (CHT) with induction CHT and radiotherapy (RT), each followed by surgery; (B) either induction CHT or induction RT-CHT, each followed by surgery, with definitive RT-CHT (no surgery). Due to the heterogeneity of patient, tumor and treatment characteristics across these trials, various meta-analyses (MAs) have been performed to define the optimal treatment approach in this setting for this clinical presentation...

BACKGROUND: Guidelines for the treatment of nonmetastatic inflammatory breast cancer (IBC) using trimodality therapy (TT) (chemotherapy, surgery, and radiotherapy) have remained largely unchanged since 2000. However, many patients with nonmetastatic IBC do not receive TT. It is unknown how patient-level (PL) and facility-level (FL) factors contribute to TT use. METHODS: Using the National Cancer Data Base, patients with nonmetastatic IBC who underwent locoregional treatment from 2003 through 2011 were identified...
