Importance: The current staging system of gastric cancer is not adequate for defining a prognosis and predicting the patients most likely to benefit from chemotherapy. Objective: To construct a survival prediction model based on specific tumor and patient characteristics that enables individualized predictions of the net survival benefit of adjuvant chemotherapy for patients with stage II or stage III gastric cancer. Design, Setting, and Participants: In this multicenter retrospective analysis, a survival prediction model was constructed using data from a training cohort of 746 patients with stage II or stage III gastric cancer who satisfied the study's inclusion criteria and underwent surgery between January 1, 2004, and December 31, 2012, at Nanfang Hospital in Guangzhou, China...

This study aimed to investigate the feasibility of the establishment of a human cancer xenograft model using samples from computed tomography (CT)-guided percutaneous biopsy. Fresh tumor tissues obtained from 10 cancer patients by CT-guided percutaneous biopsy were subcutaneously inoculated into NOD-Prkdcem26Il2rgem26Nju (NCG) mice to establish human patient-derived tumor xenograft (PDTX) models. The formation of first and second generation xenografts was observed, and tumor volume was recorded over time. Tumor tissue consistency between the PDTX model and primary tumors in patients was compared using H&E staining and immunohistochemistry...

OBJECTIVE: Analyze the probability of specific survival and factors associated with the risk of death of patients with prostate cancer who received outpatient cancer treatment in the Brazilian Unified Health System, Brazil. METHODS: Retrospective cohort study using the National Database of Oncology, developed through the deterministic-probabilistic pairing of health information systems: outpatient (SIA), hospital (SIH) and mortality (SIM). The probability of overall and specific survival was estimated by the time elapsed between the date of the first ambulatory treatment, from 2002 to 2003, until the patient's death or the end of the study...

REVIEW
Katie E Gilligan, Róisín M Dwyer
There remains an urgent need for novel therapeutic strategies to treat metastatic cancer, which results in over 8 million deaths annually worldwide. Following secretion, exosomes are naturally taken up by cells, and capable of the stable transfer of drugs, therapeutic microRNAs and proteins. As knowledge of the biogenesis, release and uptake of exosomes continues to evolve, and thus also has interest in these extracellular vesicles as potential tumor-targeted vehicles for cancer therapy. The ability to engineer exosome content and migratory itinerary holds tremendous promise...

β-thalassemia major is a hereditary anemia resulting from defects in β-globin production. It is also characterized by a hypercoagulable state with an increased risk of thrombosis. Thalidomide, a drug known for its immunomodulating and antiangiogenic properties, has recently been demonstrated to induce γ-globin gene expression and to increase the proliferation of erythroid cells. An increasing incidence of thromboembolic events in thalidomide-treated patients has been reported. This is often in the context of thalidomide combinations with other drugs, including steroids and particularly anthracycline-based chemotherapy, and with very low incidence of thrombosis with single-agent thalidomide treatment...

BACKGROUND: As no standard chemotherapy exists for pancreatoblastoma (PB), surgical resection is the most effective way of achieving complete remission. CASE REPORT: A 3-year-old girl with PB causing portal vein obstruction was referred to our hospital. Because of the portal vein involvement, she initially received 5 cycles of preoperative chemotherapy after biopsy, consisting of cyclophosphamide, vincristine, pirarubicin, and cisplatin. After chemotherapy, she underwent distal pancreatectomy, and the tumor was resected completely...

BACKGROUND: The delay in immune reconstitution after hematopoietic stem cell transplantation (HSCT), especially a delay in central immune reconstitution, leads to opportunistic infections and disease relapse after transplantation and affects the long-term outcome of HSCT. This delay is mainly attributable to thymic damage after myeloablative chemotherapy and radiotherapy METHODS: We established a model of allogeneic bone marrow transplantation (BMT) in mice and administered ghrelin (GRL) 7 days before the conditioning regimen or the day after BMT...

Lung cancer is the third most common cancer in the United States and the top cause of cancer-related mortality in men and women. Despite advances in chemotherapy, molecular therapies, and CT screening, overall survival remains dismal. Additional options and a new treatment paradigm are needed. This article focuses on immunotherapy, a promising new approach targeted at the PD-1 inhibition pathway.

RATIONALE: The optimal therapeutic regimen for primary malignant melanoma of the esophagus (PMME) need to be further elucidated. Besides, the efficacy of surgery for PMME with remote metastasis is uncertain for its rarity. PATIENT CONCERNS: Herein a previously healthy patient was admitted for dysphagia and fatigue, without significant weight loss. DIAGNOSES: The pathological and molecular tests revealed his diagnosis of BRAF-mutant, advanced PMME with localized pulmonary metastasis...

RATIONALE: Jaw metastasis is a very rare condition associated with lung cancer evolution. In this paper we present two cases of patients who underwent different approach.Lung cancer is the leading cause of cancer related death worldwide. Survival depends on the staging and biology of tumor. Smoking may affect the prognosis. PATIENT CONCERNS: There are herein reported the cases of two patients affected by squamous cell lung cancer with spread to mandibular bone. DIAGNOSES: In the first case a computed tomography (CT scan) showed a large mass located in upper right lung , then bronchoscopy was performed with biopsies and the histology revealed a squamous cell carcinoma P63+ and TTF-...

The aim of this retrospective analysis was to evaluate the antimicrobial resistance, clinical features, and risk factors for septic shock and death of nosocomial E coli bacteremia in adult patients in a single hematological center in China. A retrospective case-control study of 157 adult hematological patients with 168 episodes of E coli bacteremia was initiated from April 2012 to July 2015. Antimicrobial susceptibility as well as antimicrobial co-resistance rates were analyzed. Clinical features and outcomes were also studied...

To identify prognostic factors for overall survival after recurrence (OSr) in endometrioid endometrial cancer (EC) patients and categorize patient subgroups that predict outcomes using these variables.Consecutive patients with recurrent endometrioid EC seen in our institution from 1989 to 2013 were retrospectively reviewed. Cox regression models were used to identify the clinicopathological factors associated with OSr. By summing scores proportionate to the hazard ratio (HR) for each significant variable, we stratified patients into 3 risk groups...

This study was designed to investigate the effect of laparoscopic gastrectomy on adjuvant chemotherapy in patients with gastric cancer.Patients with gastric cancer who underwent radical gastrectomy at our institution from January 2008 to January 2015 with R0 resection, as determined by a pathological examination, were included in this study. According to the surgical approach, patients were divided into the laparoscopic gastrectomy (LG) group and open gastrectomy (OG) group. Short-term and long-term outcomes were compared between the 2 groups...

Although non-small cell lung cancer (NSCLC) patients benefit from standard taxane-platin chemotherapy, many relapse, developing drug resistance. We established preclinical taxane-platin-chemoresistance models and identified a 35-gene resistance signature, which was associated with poor recurrence-free survival in neoadjuvant-treated NSCLC patients and included upregulation of the JumonjiC lysine demethylase KDM3B. In fact, multi-drug-resistant cells progressively increased the expression of many JumonjiC demethylases, had altered histone methylation, and, importantly, showed hypersensitivity to JumonjiC inhibitors in vitro and in vivo...

Multimodal treatment in high-risk neuroblastoma has modestly improved survival; limited data exist on the late effects from these regimens. We report the sequelae of treatment incorporating 3 consecutive cycles of high-dose therapy and autologous stem cell transplants (ASCTs) without the use of total body irradiation (TBI). We reviewed the medical records of 61 patients treated on or following the Chicago Pilot 2 protocol between 1991 and 2008. Of the 25 patients who are alive (41%), 19 had near complete data to report...
