Recent sequencing studies demonstrated the MYD88 L265P mutation in more than 70% of primary central nervous system lymphomas (PCNSL), and the clinical significance of this mutation has been proposed as diagnostic and prognostic markers in PCNSL. On the other hand, mutational analyses using cell-free DNAs have been reported in a variety of systemic lymphomas. To investigate how sensitively the MYD88 L265P mutation can be identified in cell-free DNA from PCNSL patients, we performed droplet digital PCR (ddPCR) and targeted deep sequencing (TDS) in consecutive 14 PCNSL patients from whom paired tumor-derived DNA and cell-free DNA was available at diagnosis...

PURPOSE: Shared decision-making in acute myeloid leukemia (AML) requires understanding patients' longitudinal experiences of illness, but little is known about the impact of remission status on patient-reported outcomes (PROs). We aimed to explore the association between remission status and PROs 6-12 months following induction chemotherapy. METHODS: Forty-two patients completed three validated instruments characterizing symptom burden (Patient Care Monitor v2...

PURPOSE: Diffuse intrinsic pontine glioma (DIPG) remains the main cause of death in children with brain tumors. Given the inefficacy of numerous peripherally delivered agents to treat DIPG, convection enhanced delivery (CED) of therapeutic agents is a promising treatment modality. The purpose of this study was to determine which MR imaging type provides the best discrimination of intratumoral heterogeneity to guide future stereotactic implantation of CED catheters into the most cellular tumor regions...

The prognostic value of anaplastic lymphoma kinase (ALK) expression in patients with anaplastic large-cell lymphoma (ALCL) remains controversial. Data on the clinical features of ALCL in a Chinese population are limited. We retrospectively reviewed 1293 patients with pathologically diagnosed lymphoma at Guangdong General Hospital from June 2007 through August 2016. We evaluated the incidence of ALCL, clinical characteristics, survival status, and outcome of crizotinib use in four relapsed/refractory ALK-positive patients...

In recent years, studies have suggested a novel pathway for cell survival, which faces scientific skepticism and interest in its concept of cell 'resurrection' - that is, the anastasis of cells at late-stage apoptosis. While biomarkers have been discovered, many of these are related to the endoplasmic reticulum (ER) stress response - acting also to promote cell survival in the presence of perturbation. The promises of anastasis, if accepted, will greatly impact translational medicine especially in the treatment of cancer, since apoptosis is generally irreversible in the late stages, and chemotherapy is performed to maximize tumor death and minimize off-target effects...

BACKGROUND: The aim of ESCAP-2011-CPHG, promoted by the French College of General Hospital Respiratory Physicians, was to describe therapeutic strategies in lung cancer in the first 2 years after diagnosis, in a real-life setting. This article focuses on patients undergoing surgical management of a non-small cell lung cancer (NSCLC). METHODS: A prospective multicentre study was conducted in 53 French general hospitals. For each patient with lung cancer diagnosed in 2010, a standardised form was completed following each change in treatment strategy up to 2 years after diagnosis...

BACKGROUND: PARP inhibitors are currently evaluated in combination with radiotherapy and/or chemotherapy. As sensitizers, PARP inhibitors are active at very low concentrations therefore requiring highly sensitive pharmacodynamic (PD) assays. Current clinical PD-assays partly fail to provide such sensitivities. The aim of our study was to enable sensitive PD evaluation of PARP inhibitors for clinical sensitizer development. MATERIAL AND METHODS: PBMCs of healthy individuals and of olaparib and radiotherapy treated lung cancer patients were collected for ELISA-based PD-assays...

BACKGROUND: The emergence of oligoclonal bands, proteins differing from those originally identified at diagnosis, has been reported in multiple myeloma patients after high-dose chemotherapy followed by autologous stem cell transplantation and after successful conventional chemotherapy. The clinical relevance of oligoclonal bands remains unclear, but their emergence has been associated with better prognosis. The aim of the present study was to determine the prevalence, clinical characteristics and prognostic impact of the presence of oligoclonal bands in multiple myeloma patients...

Cancer is a disease of the elderly as demonstrated by the epidemiological evolution of Western countries. Indeed, two third of cancers newly diagnosed occur over 65 years. However, older cancer patients have been often excluded from clinical trials in oncology and the extrapolation of cancer treatments in this population remains difficult in practice. Scientific societies recommend that a comprehensive geriatric assessment (CGA) be performed in patients aged 70 and over and selected using screening tools for frailty such as the G8 index...

REVIEW

Synchronous lung and esophageal cancers are rare but represent a unique challenge to thoracic surgeons. The literature is limited but series describe long-term survival with curative surgery for concomitant esophageal and lung cancer. Preoperative risk assessment is critical because surgical resection of both cancers requires adequate cardiopulmonary function and performance status. Chemotherapy and radiation are used as adjuvant therapy or as primary treatment of unresectable lesions. Although long-term survival for patients with concomitant lung and esophageal cancer is lower than that of patients with either one alone, survival with curative surgery is higher than that of patients with metastatic disease of either primary...

REVIEW
Matthew Low, Sharon Ben-Or
Small cell lung cancer (SCLC) has a complex history and remains difficult to treat. Most patients with SCLC present with metastases or extensive stage disease, rendering most not amenable to surgical resection. Until recently, chemoradiotherapy had become the standard of care for all patients with SCLC. However, recent studies have shown improved survival following surgical resection with chemotherapy in patients with early-stage SCLC, specifically those with stage I disease. This article presents the literature on treatment of early-stage SCLC and addresses the question of whether surgery should be considered a viable treatment modality...

BACKGROUND: Cytoreductive surgery (CRS) plus hyperthermic intra-operative peritoneal chemotherapy (HIPC) for gastric peritoneal carcinomatosis (PC) is controversial, and selection criteria for this treatment modality are lacking. METHODS: Thirty-two patients (F/M ratio 12/20; median (range) age 58 (32-75) years) underwent CRS + HIPC with cisplatin for PC from gastric adenocarcinoma in 2010-2014. This monocentric phase-2 nonrandomized prospective study with a power of 90% aimed to improve the 1-year overall survival (OS) rate with 40% (historical reference of 52% to 72%)...

Tumor cell chemoresistance is a major challenge in cancer therapeutics. Major select metal-based drugs are potent anticancer agents yet they exhibit undesirable side-effects and are effective against only a few types of cancers. A need, therefore, arises for new metallodrugs with an improved spectrum of efficacy and lower toxicity. Development of anticancer drugs based on antitumor metals is currently a very active field, with considerable efforts having been made toward elucidating the mechanisms of immune action of complex metalloforms and optimizing their immunoregulatory bioactivity through appropriate structural modification...

BACKGROUND: The GETUG 13 phase III trial tested personalised chemotherapy based on tumour marker decline in patients with poor-prognosis germ-cell tumour (GCT) and demonstrated that a dose-dense regimen improves progression-free survival in patients with an unfavourable decline. We investigated the pattern of relapse for patients included in GETUG 13. METHODS: We conducted an analysis of relapse events in patients from GETUG 13. Baseline procedures before inclusion in the trial comprised a thoraco-abdomino-pelvic computed tomography scan and a magnetic resonance imaging of the brain...

PURPOSE: L-type amino acid transporter 1 (LAT1) is linked to tumor cell proliferation, angiogenesis, and survival in various human cancers. Although the expression of LAT1 was identified as a significant prognostic predictor after surgery in patients with pancreatic ductal adenocarcinoma (PDAC), little is known about the clinical significance of LAT1 as a chemotherapeutic resistance factor in PDAC. METHODS: A total of 110 patients with surgically resected PDAC were retrospectively reviewed as the training set...

The translationally controlled tumor protein (TCTP) is a highly conserved protein that is regulated due to a high number of extracellular stimuli. TCTP has an important role for cell cycle and normal development. On the other side, tumor reversion and malignant transformation have been associated with TCTP. TCTP has been found among the 12 genes that are differentially expressed during mouse oocyte maturation, and an overexpression of this gene was reported in a wide variety of different cancer types. Its antiapoptotic effect is indicated by the interaction with several proapoptotic proteins of the Bcl-2 family and the p53 tumor suppressor protein...

An intrarenal approach using a percutaneous nephrostomy tube is a novel method to deliver chemotherapy and biotherapy to patients with upper urinary tract urothelial carcinoma. A paucity of evidence exists regarding basic nursing implications for this unique treatment option. This column will provide suggested guidelines to administer intrarenal treatment via a percutanous nephrostomy tube.
