Prostate cancer is the most common solid tumor malignancy in men worldwide. Treatment with surgery and radiation can be curative in organ-confined disease. Unfortunately, about one third of men develop biochemically recurrent disease based only on rising prostate-specific antigen (PSA) in the absence of visible disease on conventional imaging. For these patients with biochemical recurrent prostate cancer, there is no uniform guideline for subsequent management. Based on available data, it seems prudent that biochemical recurrent prostate cancer should initially be evaluated for salvage radiation or prostatectomy, with curative intent...

Galactomannan films from Cassia grandis seeds, associated or not with Cramoll 1,4, were used on topical wounds of rats for the evaluation of the healing process during 14 days. All of the films were evaluated by cytotoxic assay, FTIR and lectin hemagglutinating activity (HA). Forty-five male rats were submitted to aseptic dermal wounds (Ø=0.8cm) and divided in groups (n=15): control, test 1, and test 2, treated respectively with saline, galactomannan film and film with immobilized Cramoll 1,4. Macroscopic evaluations were performed by clinical observations and area measurements, and microscopic analysis by histological criteria...

Alternative promoter usage, alternative splicing and alternative cleavage/polyadenylation (referred here as to alternative transcription and splicing) are main instruments to diversify the transcriptome from a limited set of genes. There is a good deal of evidence that chemotherapeutic drugs affect these processes, but the therapeutic incidence of these effects is poorly documented. The scope of this study is to review the impact of chemotherapy on alternative transcription and splicing and to discuss potential implications in cancer therapy...

INTRODUCTION: Nodal ratio (NR) has been demonstrated to be an independent prognostic factor in patients with gastric cancer. We evaluated the prognostic role of NR comparing it with the current TNM (2010) classification in gastric cancer patients treated with curative (R0) D1 resection. MATERIALS AND METHODS: We retrospectively reviewed 110 patients who underwent R0 resection for gastric cancer at University Hospital of Larissa between 2002 and 2011. All patients had a D1 lymphadenectomy plus the nodes along the left gastric artery...

Mood disorders are wide spread with estimates that one in seven of the population are affected at some time in their life (Kessler et al., 2012). Many of those affected with severe depressive disorders have cognitive deficits which may progress to frank neurodegeneration. There are several peripheral markers shown by patients who have cognitive deficits that could represent causative factors and could potentially serve as guides to the prevention or even treatment of neurodegeneration. Circadian rhythm misalignment, immune dysfunction and oxidative stress and circadian rhythm misalignment are key pathologic processes implicated in neurodegeneration and cognitive dysfunction in depressive disorders...

BACKGROUND: In rectal cancer, anastomotic leakage was reported to have a negative impact on both short- and long-term outcomes. However, there is limited data on the impact of anastomotic leakage on oncologic outcomes in patients with colon cancer. We aimed to evaluate the impact of anastomotic leakage on disease recurrence and long-term survival after curative resection of colon cancer. METHODS: This multicenter, retrospective cohort study of 4,919 consecutive patients utilized data from the Japanese Society for Cancer of the Colon and Rectum...

Liver transplantation (LT) is a life-saving and curative treatment for Wilson disease (WD), providing restoration of function of the liver and mitigation of portal hypertension. Indications for LT in patients with WD include acute liver failure or end-stage liver disease not treatable by medical therapy. LT is also used to treat hepatocellular carcinoma when it develops in patients with WD when tumor resection is not feasible. LT solely for neurologic or psychiatric WD remains controversial. Living liver donation as well as cadaveric orthotopic and auxiliary LT are options for transplantation for WD...

BACKGROUND: Considering that pneumonectomy itself is a disease, avoidance of pneumonectomy needs to be deliberated. Herein, we evaluated the role of neoadjuvant chemoradiotherapy for avoidance of pneumonectomy in patients with centrally located locally advanced non-small cell lung cancer. METHODS: Patients who underwent neoadjuvant chemoradiotherapy after being judged to require pneumonectomy by cancer board between 1997 and 2011 were retrospectively evaluated. RESULTS: Twelve patients, including 10 males and 2 females with median age 63...

Surgical resection of metastases represents an integral part of curative management in patients with testicular germ cell tumors (GCT). Primary nerve-sparing retroperitoneal lymph node dissection (nsRPLND) for low volume metastases in clinical stages I-IIB has to be differentiated from the more complex and more extensive postchemotherapeutic procedures. In Europe, primary nerve-sparing retroperitoneal lymph node dissection (nsRPLND) for clinical stage I nonseminomatous GCT (NSGCT) plays a subordinate. In clinical stage IIA/B, nsRPLND is indicated for patients with marker-negative metastases in whom cure rates of about 65% can be achieved with surgery alone...

BACKGROUND AND AIMS: The effects of chemotherapeutic agents on the development of colorectal adenomas in patients with previous colorectal cancer (CRC) are not defined. Therefore, we evaluated the potential effect of adjuvant chemotherapy on the incidence of colorectal adenomas in patients with previous CRC. METHODS: We selected patients with low-risk stage II CRC with or without postoperative 5-fluorouracil-based adjuvant chemotherapy to reduce selection bias. Among 1808 patients with stage II CRC who underwent colonoscopic surveillance after curative resection of CRC between 2006 and 2013, 192 patients were retrospectively enrolled in this study after matching for age and sex...

BACKGROUND: Due to a lack of consensus on adjuvant treatments for pT1N1 gastric cancer, surgeons face a dilemma when deciding treatments for patients with pT1N1 gastric cancer after gastrectomy. The objective of this study was to determine survival benefits of adjuvant chemotherapy and risk factors for tumor recurrence in gastric cancer patients with pT1N1. METHODS: Between 1996 and 2010, 510 patients who underwent curative resection for pT1N1 gastric cancer at three institutes were divided into two groups: adjuvant chemotherapy group (N = 150) and surgery-only group (N = 360)...

BACKGROUND: In studies of recurrent events, it is common to consider a person who has suffered a disease episode and received curative treatment to be not at risk of suffering a new episode for a duration of time. It is a common practice to deduct this duration from the person's observation time in the statistical analysis of the incidence data. METHODS: We examined the concepts of incidence and protective efficacy from a real life point of view. We developed simple formulae to show the relationship between the incidence rate and protective efficacy between analyses with and without deducting the curative treatment time from the observation time...

For the majority of patients with newly diagnosed follicular lymphoma (FL), current treatments, while not curative, allow for long remission durations. However, several important needs remain unaddressed. Studies have consistently shown that approximately 20% of patients with FL experience disease progression within 2 years of first-line treatment, and consequently have a 50% risk of death in 5 years. Better characterization of this group of patients at diagnosis may provide insight into those in need of alternate or intensive therapies, facilitate a precision approach to inform clinical trials, and allow for improved patient counseling...

Prostate cancer is a main urological disease associated with significant morbidity and mortality. Radical prostatectomy and radiotherapy are potentially curative for localized prostate cancer, while androgen deprivation therapy is the initial systemic therapy for metastatic prostate disease. However, despite temporary response, most patients relapse and evolve into castration resistant cancer.Epithelial-mesenchymal transition (EMT) is a complex gradual process that occurs during embryonic development and/or tumor progression...

The aim of this study was to retrospectively compare the long-term efficacy of MW ablation as a curative therapy for hepatocellular carcinoma(HCC) adjacent to large vessels(≥3 mm) with that in safe location. Between 2010 and 2016, 406 patients diagnosed with early-stage HCC at Chinese PLA general hospital were enrolled. One-to-one matched pairs between the vessel group and the safe group were generated using propensity score matching. The associations of treatment strategy with overall survival and local tumor progression were determined by Cox regression...

1,4-Pentadien-3-one derivatives derived from curcumin possess excellent inhibitory activity against plant viruses. On the basis of this finding, a series of novel 1,4-pentadien-3-one derivatives containing a 1,3,4-thiadiazole moiety were designed and synthesized, and their structures confirmed by IR, ¹H-NMR, and (13)C-NMR spectroscopy and elemental analysis. The antiviral activities of the title compounds were evaluated against tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV) in vivo. The assay results showed that most of compounds had remarkable antiviral activities against TMV and CMV, among which compounds 4b, 4h, 4i, 4k, 4o, and 4q exhibited good curative, protection, and inactivation activity against TMV...
