OBJECTIVE: Gastric cancer is the most common gastrointestinal malignancy and the leading cause of cancer-related deaths in East Asia. Increasing evidence has revealed that autophagy is closely associated with tumor initiation and progression. The present work aimed to investigate the role of autophagy in adjuvant chemotherapy for gastric cancer. MATERIALS AND METHODS: Gastric cancer stem cells (CSCs) were isolated from gastric cancer cell lines using the cell surface markers CD44 and CD54 and cultured in a three-dimensional cell culture system...

Background: Aromatase inhibitors improve disease-free survival compared with tamoxifen in postmenopausal women with hormone receptor-positive breast cancer. The Tamoxifen and Exemestane Adjuvant Multinational (TEAM) trial compared exemestane monotherapy with sequential therapy of tamoxifen followed by exemestane. The trial failed to show a statistically significant difference between treatment arms. A robust translational program was established to investigate predictive biomarkers. Methods: A tissue microarray was retrospectively constructed using a subset of patient tissues (n = 4631) from the TEAM trial (n = 9766)...

PURPOSE OF REVIEW: To provide an updated perspective on the use of probiotics as adjuvant treatment strategy for patients suffering from or at risk of developing mucositis. RECENT FINDINGS: Studies suggest that oral and intestinal microbiota could be relevant to mucositis development and treatment, but no clear high-risk pattern has been identified and no single probiotic formulation has emerged from human clinical trials for strong recommendation. Promising results from available clinical trials suggest their use in patients with peri-implant mucositis or at risk of anticancer treatment-related oral or intestinal mucositis...

AIM: Recently, D,L-methadone has been put forward as adjuvant treatment in glioblastoma (GBM). METHODS: We analyzed the μ-opioid receptor expression in a set of GBM cell lines and investigated the efficacy of D,L-methadone alone and in combination with temozolomide (TMZ). Results & conclusion: Expression of the μ-opioid receptor was similar in the tested cell lines. High concentrations of D,L-methadone induced apoptosis in all cell lines and showed treatment interaction with TMZ...

PURPOSE: A meta-analysis of 22 randomized trials accrued from 1964 to 1986 demonstrated significantly higher rates of locoregional failure (LRF) and breast-cancer mortality in women with 1-3 positive nodes without postmastectomy radiotherapy (PMRT) after mastectomy (mast.). Recent data demonstrate that PMRT reduces distant metastases (DM) in women with pN1 disease. The challenge today is whether all patients with pathologic T1-2pN1 disease have similar substantial LRF/DM risk that routinely warrants PMRT...

This study evaluates a novel technique of laparoscopic ovarian transposition performed by Gynecologic Oncologists prior to pelvic radiation for gynecologic cancer. A retrospective review was completed of all patients that underwent laparoscopic ovarian transposition from February 2007 to June 2017 at one tertiary care cancer. The technique involves salpingectomy, followed by retroperitoneal dissection to move the ovaries lateral to the hepatic and splenic flexures of the colon. Normal ovarian function was defined by the absence of vasomotor symptoms, FSH and menstrual history (if menstruating)...

A robust and accurate gene expression signature is essential to assist oncologists to determine which subset of patients at similar Tumor-Lymph Node-Metastasis (TNM) stage has high recurrence risk and could benefit from adjuvant therapies. Here we applied a two-step supervised machine-learning method and established a 12-gene expression signature to precisely predict colon adenocarcinoma (COAD) prognosis by using COAD RNA-seq transcriptome data from The Cancer Genome Atlas (TCGA). The predictive performance of the 12-gene signature was validated with two independent gene expression microarray datasets: GSE39582 includes 566 COAD cases for the development of six molecular subtypes with distinct clinical, molecular and survival characteristics; GSE17538 is a dataset containing 232 colon cancer patients for the generation of a metastasis gene expression profile to predict recurrence and death in COAD patients...

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are combined to treat peritoneal surface malignancies (PSM). The objective of cytoreduction is to eradicate macroscopic disease, while HIPEC addresses residual microscopic disease. Currently, there are no protocols guiding treatment of cirrhotic patients with PSM. We report the case of a cirrhotic patient with signet ring cell (SRC) appendiceal adenocarcinoma who underwent normothermic, as opposed to hyperthermic intraperitoneal chemotherapy (IPC)...

Vaccines against a variety of infectious diseases have been developed and tested. Although there have been some notable successes, most are less than optimal or have failed outright. There has been discussion about whether either B cells or dendritic cells (DCs) could be useful for the development of antimicrobial vaccines with the production of high titers of antibodies. Invariant (i)NKT cells have direct antimicrobial effects as well as adjuvant activity, and iNKT-stimulated antigen-presenting cells (APCs) can determine the form of the ensuing humoral and cellular immune responses...

Venous ulcer is an extremely common aetiology of lower extremity ulceration, which affects approximately 1% population in most of the countries, and the incidence rate increases with age and female gender. Proper assessment and diagnosis of both the patient and ulcer are inevitable in order to differentiate venous ulcers from other lower extremity ulceration and to frame an adequate and individualised management plan. Venous ulcers generally persist for weeks to many years and are typically recurrent in nature...

Information on patterns of clinical care for elderly breast cancer patients is lacking. The aims of this study are two-fold, firstly, to clarify daily practice treatments for elderly breast cancer patients in Japan, and secondly, to plan a prospective clinical trial to address unresolved clinical questions. We investigated practice care of elderly breast cancer patients in 38 institutions of the Japan Clinical Oncology Group (JCOG). Questionnaires asked: (1) definition of "elderly" for each treatment, (2) clinical standard anti-HER2 therapy in each age-group, (3) recommended docetaxel dose in each age-group, (4) considerations for future clinical trials, and (5) other information about geriatric oncology concerning breast cancer...

Gonorrhea, an important sexually transmitted disease, is becoming a growing public health problem around the globe. Vaccination is considered the best long-term approach for control of infection. In this study, we designed a novel Neisseria gonorrhoeae (N. gonorrhoeae) DNA vaccine delivered by bacterial ghosts and characterized its immune responses in vitro and in vivo. Our results demonstrate that bacterial ghosts greatly promoted BMDCs maturation and activation. Bacterial ghosts loaded with N. gonorrhoeae DNA vaccine were efficiently taken up by mouse macrophage RAW264...

INTRODUCTION: Breast cancer patients with tumors > 5 cm but without nodal disease who undergo mastectomy present a clinical challenge regarding the appropriate adjuvant treatment. Traditionally, postmastectomy radiation therapy (PMRT) was the standard of care. However, recent studies have suggested local failure rates without PMRT might be low enough to omit RT. This might be especially true in the elderly. PATIENTS AND METHODS: Women aged ≥ 75 years with a diagnosis of T3N0 breast cancer who had undergone mastectomy were identified from the Surveillance, Epidemiology, and End Results (SEER) 18 database...

Botrytis cinerea is the pathogen of gray mold disease affecting a wide range of plant hosts, with consequential economic losses worldwide. The increased frequency of fungicide resistance of the pathogen challenges its disease management, and thus the development of alternative control strategies are urgently required. In this study, we showed excellent synergistic interactions between resveratrol and pyrimethanil. Significant synergistic values were recorded by the two-drug combination on the suppression of mycelial growth and conidia germination of B...
