Purpose: To identify the maximum tolerated dose (MTD) and describe dose-limiting toxicities (DLT) of pemetrexed and oxaliplatin given on a once-every-2-week schedule in patients with metastatic cancer.
Patients And Methods: Twenty-five patients were enrolled. Due to toxicities observed at the first dose level in unselected patients, a second MTD was determined in patients who had received zero to two prior chemotherapy regimens.
Ependymoblastomas are distinct embryonal tumors of the central nervous system reported only rarely in the literature. Most examples arise in young children under the age of 2 years, in the supratentorial compartment, and may or may not be related to the ventricular system. We report the case of a one-day-old infant who presented with a 6.

With these observations, we designed a phase II trial to evaluate the efficacy and safety of erlotinib plus celecoxib in advanced NSCLC.
Experimental Design: Previously treated stage IIIB/IV NSCLC patients were given celecoxib at 400 mg orally twice daily and erlotinib at 150 mg orally daily until disease progression.

Thermal sealing devices, such as the LigaSure (ValleyLab-Tyco Healthcare; Boulder, CO) or Gyrus PK (Gyrus ACMI, Maple Grove, MN) are minimally invasive instruments that can be used to seal the pulmonary parenchyma in pediatric lung resections. But these devices were only available in laparoscopic form, and no robotically similar instruments were manufactured. This handicaps the surgeon at the console, because these nonrobotic instruments must be manipulated and used by the bedside assistant instead of the console surgeon.

Patients And Methods: Patients (n = 101) with BAC (n = 12) or adenocarcinoma, BAC subtype (n = 89), were enrolled. All patients received erlotinib 150 mg daily.
Background: E4599 was a phase II/phase III trial, in which 878 patients with advanced non-small cell lung cancer were randomized to carboplatin + paclitaxel (PC arm) or PC + bevacizumab (BPC arm). Survival and progression-free survival were superior on the BPC arm. The rationale for markers used in this correlative study was based on elevated vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), soluble intercellular adhesion molecule (ICAM) and E-selectin in a variety of malignancies and changes in response to endothelial cell apoptosis.

Background: The purpose of this study was to examine the efficacy and acceptability of an open-label conditioned placebo dose reduction (CPDR) treatment in 70 children with attention deficit hyperactivity disorder (ADHD). This paper focuses on the qualitative data from the study.
Methods: Following a double-blind, crossover dose finding procedure to determine each subject's optimal dose of stimulant medication, subjects were randomized to the CPDR treatment or one of two control groups.

Background: This study examined short-term efficacy, side effects and acceptability of a placebo treatment procedure designed to maintain children with attention deficit hyperactivity disorder (ADHD) on 50% of their usual stimulant dose.
Methods: An open-label prospective crossover trial was conducted in 26 children with ADHD, ages 7-15 years, stable on stimulant therapy, followed at a community-based developmental paediatrics ADHD clinic. Subjects were randomly assigned to one of two orders of experimental conditions: (1) baseline (100%) dose (1 week), then 50% dose (1 week), then 50% dose + placebo (1 week), or (2) baseline (100%), then 50% dose + placebo, then 50% dose.
Purpose: Fit elderly patients with advanced non-small-cell lung cancer (NSCLC) benefit from platinum-based, two-drug chemotherapy. Bevacizumab (B) in combination with carboplatin (C) and paclitaxel (P) improves survival for advanced, nonsquamous NSCLC, as evidenced in Eastern Cooperative Oncology Group (ECOG) 4599. We conducted a subset analysis of ECOG 4599 to determine the outcome for elderly patients.
View Article and Find Full Text PDFPurpose: Robotic technology allows surgeons to perform complex procedures which may be difficult with standard laparoscopic instruments. We believe that complex hepatobiliary procedures are ideally suited for robotic surgery in children and present our experience with Kasai portoenterostomy and excision of choledochal cysts.
Methods: We performed 4 complex hepatobiliary procedures in children using the Da Vinci surgical robot (Intuitive Surgical, Sunnyvale, CA): 2 Kasai portoenterostomies and 2 choledochal cyst resections.
Background: Robotic surgery is a new technology that may eventually replace laparoscopy in treating many surgical issues in children. Resident education using robotic surgery has been a concern for many institutions. We present our first 50 consecutive robotic fundoplications in children and our teaching experience with this procedure.

Iatrogenic splenic injury requiring splenectomy is a well-recognized and potentially serious complication of colon resection. Iatrogenic splenectomy is associated with significant morbidity and mortality, including bleeding and the postsplenectomy sepsis syndrome. Our study aims to compare the incidence of iatrogenic splenectomy in laparoscopic colon resection with that of open colon resection over an 11-year-period at Mount Sinai.

Although the anomaly has been approached from both the abdomen and the chest, the defect can be difficult to close as the posterolateral region may be difficult to reach with precise suturing using standard rigid laparoscopic instruments. The articulating instruments of robotic surgery offer a substantial improvement in degrees of freedom and may help over come these obstacles.

Methods: A MEDLINE search was performed to identify pertinent peer-reviewed articles that addressed the questions posed for this section. The writing committee developed and graded recommendations, which were subsequently approved by the American College of Chest Physicians.
Purpose: Bevacizumab, a humanized anti-vascular endothelial growth factor monoclonal antibody, and erlotinib, a reversible, orally available epidermal growth factor receptor tyrosine kinase inhibitor, have demonstrated evidence of a survival benefit in the treatment of non-small-cell lung cancer (NSCLC). A single-arm phase I and II study of bevacizumab plus erlotinib demonstrated encouraging efficacy, with a favorable safety profile.
Patients And Methods: A multicenter, randomized phase II trial evaluated the safety of combining bevacizumab with either chemotherapy (docetaxel or pemetrexed) or erlotinib and preliminarily assessed these combinations versus chemotherapy alone, as measured by progression-free survival (PFS).
Angiogenesis and its role in the growth and development of metastases has become a topic of increasing importance. In non-small cell lung cancer (NSCLC), vascular endothelial growth factor (VEGF) plays an important role in angiogenesis, growth of the primary tumor, and development of metastases. In addition, elevated expression in tissue samples is a negative prognostic feature.

Background: Clusterin is a glycoprotein that has been implicated in many processes, including apoptosis, cell cycle regulation, and DNA repair. Previous studies have examined the prognostic value of clusterin expression in various malignancies. In the present study, we examined clusterin staining in tumors resected from patients with non-small cell lung cancer (NSCLC).

During the summer months aerosols collected in Israel are highly polluted by metals (EF(Ni) = 120, EF(Cu) = 320, EF(Zn) = 30, EF(Pb) = 540; average values). The fraction of European Pb of mostly industrial sources is 61 +/- 21% in Jerusalem, and the fraction of European Cu, Zn, Ni, and aerosols should be on the same order.

Vascular endothelial growth factor (VEGF) is a key angiogenic factor implicated in tumor blood vessel formation and permeability. Overexpression of VEGF has been observed in a variety of cancers and has been associated with a worse relapse-free and overall survival.

Despite advances in treatment, the prognosis remains poor with recurrence rates as high as 50% after surgical resection alone. In this article, we review the rationale and evidence for neoadjuvant and adjuvant therapy with chemotherapy, radiation therapy, and combined modality therapy in patients with resected non-small cell lung cancer.
