Raman Thakur, Jata Shankar
Aspergillus terreus is an emerging opportunistic fungal pathogen that causes invasive aspergillosis in immunocompromised individuals. The main risk group of individuals for this organism is leukopenic patients, individuals having cancers, bone marrow transplant persons and those who have immunological disorders. The lack of early diagnostic marker for A. terreus and intrinsic resistance to Amphotericin B, further limits the successful therapy of A. terreus-associated infections. The germination of inhaled conidia is the key step to establish successful invasion in host tissues or organs...

PURPOSE: Invasive lobular carcinoma (ILC) of the breast has unique clinicopathologic characteristics, compared to invasive ductal carcinoma. The role of the 21-gene Recurrence Score (RS) has not been clearly defined for ILC. We sought to determine the prognostic value of RS and the impact of adjuvant chemotherapy on long-term survival in patients with ILC. METHODS: Utilizing the Surveillance, Epidemiology and End Results database from 2004 to 2013, we identified records of women aged 18-74 years, diagnosed with estrogen receptor (ER)-positive ILC (stage I to III) with RS available...

Hepatocellular carcinoma (HCC) is the sixth most common cancer and the second leading cause of cancer mortality worldwide. Incidence rates of liver cancer vary widely between geographic regions and are highest in Eastern Asia and sub-Saharan Africa. In the United States, the incidence of HCC has increased since the 1980s. HCC detection at an early stage through surveillance and curative therapy has considerably improved the 5-year survival. Therefore, medical societies advocate systematic screening and surveillance of target populations at particularly high risk for developing HCC to facilitate early-stage detection...

PURPOSE: The staging of multiple pulmonary adenocarcinomas requires the distinction of intrapulmonary metastasis (IPM) from multiple primary lung cancers (MPLC). This can be challenging in some patients, and the addition of data from oncogenic driver mutations in these tumors may be helpful in this determination. PROCEDURES: As a proof of principle, molecular driver results from primary tumors and their metastases in 45 patients were compared (cohort 1). Then, 69 patients with a total of 154 synchronous or metachronous lung carcinomas were identified, with pathologic findings compared to oncogenic driver mutation...

OBJECTIVE: Sex differences in bladder cancer survival are well known. However, the effect of type of treatment, timing to surgery when rendered, and survival outcomes according to sex have not been extensively examined. Given the relatively low incidence of bladder cancer in females, large multicenter and population-based studies are required to elucidate sex differences in survival. In this study, we sought to characterize the effect of use and timing of radical cystectomy (RC) according to sex and survival outcomes...

Preoperative contrast-enhanced (CE) breast magnetic resonance imaging (MRI) remains controversial in the newly diagnosed breast cancer patient. Additional lesions are frequently discovered in these patients with CE breast MRI. As staging and treatment planning evolve to include more information on tumor biology and aggression, so should our consideration of extent of disease. Directing CE breast MRI to those patients most likely to have additional disease may be beneficial. We sought to develop practical guidance for the use of preoperative CE breast MRI in the newly diagnosed breast cancer patient based on recent scientific data...

Researches have shown that miR-425-5p expression altered in lung, esophageal, and glial cancer. Similarly, in our previous study, we found miR-425-5p expression was up-regulated in GC cells and could promote gastric cancer (GC) cell invasion and metastasis. However, the functional mechanism and the prognostic significance of miR-425-5p in GC remain unclear. Therefore, the present study examined miR-425-5p expression in GC tissues and also evaluated miR-425-5p of the therapeutic and prognostic value. Moreover, with interference of miR-425-5p expression in cell lines, we investigated the molecular mechanism of miR-425-5p and the expression level was higher in GC tissues comparing with that in gastric tumor-adjacent mucosa...

INTRODUCTION: It is 40 years since the initial documentation of the efficacy of bacille Calmette-Guérin (BCG) in the management of non-muscle invasive bladder cancer (NMIBC) and probably an opportune a time as any to retrace the origins of this development and to reflect on the progress that has occurred on the use of immune modifiers in the treatment of NMIBC. MATERIALS AND METHODS: A PubMed search for publications on the history of BCG was conducted, and those related to the development of the vaccine for protection against tuberculosis as well as those published in the last 40 years related to its use for treatment for NMIBC were selected for review...

The importance of the P450 enzyme CYP1B1 in both cancer therapy and prevention are reviewed and evidence is discussed, which provides strong biological plausibility for the therapeutic merits of this approach. The significant resistance to chemotherapy among common cancers, and the realization that in many cases chemotherapy leaves behind drug-resistant cancer cells that eventually cause recurrence and metastatic disease, has recently prompted the search for natural compounds that would circumvent this problem...

Hepatocellular carcinoma (HCC) is one of the most aggressive and heterogeneous cancers worldwide. Herein, we demonstrate KIF4A (Chromosome-associated kinesin KIF4A) as a potential biomarker, is up-regulated in most samples of HCC. The expression level of KIF4A in tumor tissue is significantly associated with the survival time, and a significant correlation between KIF4A expression and clinical information stage, metastasis and tumor dimension was observed. We further measured the proliferation and migration ability of two HCC cell lines, HCC-LM3 and PLC/PRF/5, following KIF4A-siRNA transfection...
