Nal-IRI/LV5-FU versus paclitaxel as second-line therapy in patients with metastatic esophageal squamous cell carcinoma (OESIRI)-PRODIGE 62: A multice…

2020

Half of patients newly diagnosed with esophageal squamous cell cancer (ESCC) have metastatic disease (mESCC) and therefore a poor prognosis. Furthermore, half of patients with initial loco-regional disease present disease recurrence after surgery and/or chemoradiation. In mESCC, the recommended first-line treatment combines 5-fluorouracil and cisplatin, although this has not been validated by a phase III trial. Patients with disease progression or recurrence after platinum-based chemotherapy and good performance status probably benefit from second-line chemotherapy. Several molecules have been evaluated in phase I/II trials or retrospective studies (docetaxel, paclitaxel and irinotecan) but…

What can platinum offer yet in the treatment of PS2 NSCLC patients? A systematic review and meta-analysis

2015

Abstract: Background: Randomized phase III trials showed interesting, but conflicting results, regarding the treatment of NSCLC, PS2 population. This meta-analysis aims to review all randomized trials comparing platinum-based doublets and single-agents in NSCLC PS2 patients. Materials and methods: Data from all published randomized trials, comparing efficacy and safety of platinum-based doublets to single agents in untreated NSCLC, PS2 patients, were collected. Pooled ORs were calculated for the 1-year Survival-Rate (ly-SR), Overall Response Rate (ORR), and grade 3-4 (G3-4) hematologic toxicities. Results: Six eligible trials (741 patients) were selected. Pooled analysis showed a significan…

Looking for a new panacea in ALK-rearranged NSCLC: may be Ceritinib?

2014

Abstract: In the past decade, the advent of targeted therapy led to a silent revolution in the war against lung cancer and a significant evolution on the concept of Phase I clinical trials design. Thanks to the specificity of their target, the new drugs have radically changed NSCLC treatment, leading to the development of personalized strategies. The accelerated approval of the first ALK-inhibitor, Crizotinib and more recently Ceritinib, without a Phase III randomized, clinical trial, has been an amazing success story in lung cancer research, marking the beginning of a new decade of targeted drugs development, characterized by modern, biomarker-driven, early clinical trial design and shorte…

Cetuximab in squamous cell head and neck carcinomas.

2007

The epidermal growth factor receptor (EGFR) antagonist, cetuximab, has recently been shown to enhance the effects of radiotherapy, and reports to date indicate that this effect occurs without any change in the pattern and severity of toxicity usually associated with head and neck radiation and/or chemotherapy (CT) administration. Moreover, several studies have reported that the expression of EGFR is strongly linked to poor outcome in patients undergoing therapy. Therefore, the presence of the EGFR in almost all cases of head and neck carcinoma offers a new therapeutic opportunity to most patients. In this paper, we report a review of the major studies dealing with the use of cetuximab in ad…

Phase imaging microscopy under the Gabor regime in a minimally modified regular bright-field microscope

2021

Quantitative phase imaging (QPI) is nowadays a powerful tool for visualization and analysis of biological processes. QPI is usually attained from specifically designed optical microscopes retrieving phase information in a quantitative way. In this paper we report on an extremely simple, low cost and compact way to update a standard bright-field microscope with coherent sensing capabilities. It is based on the in-line Gabor holography concept and only needs to replace the illumination broadband source of the regular microscope with a coherent one. The proposed methodology is completed by the recording of a digital in-line Gabor hologram instead of regular imaging conditions and by the numeri…

Single-shot two-frame π-shifted spatially multiplexed interference phase microscopy

2019

Single-shot, two-frame, π-shifted spatially multiplexed interference microscopy (π-SMIM) is presented as an improvement to previous SMIM implementations, introducing a versatile, robust, fast, and accurate method for cumbersome, noisy, and low-contrast phase object analysis. The proposed π-SMIM equips a commercially available nonholographic microscope with a high-speed (video frame rate) enhanced quantitative phase imaging (QPI) capability by properly placing a beam-splitter in the microscope embodiment to simultaneously (in a single shot) record two holograms mutually phase shifted by π radians at the expense of reducing the field of view. Upon subsequent subtractive superimposition of hol…

Opioid metabolism and clinical aspects.

2015

Opioids are are commonly used for the management of acute and chronic pain. Opioids have different physicochemical and pharmacokinetic characteristics, which explain the profound changes in the clinical effect in several clinical conditions. Pharmacokinetics influences the opioid response affecting bioavailability, production of metabolites with residual clinical activity, and elimination. Generality of opioid metabolism and clinical implications for specific opioids in different clinical conditions were reviewed to bridge the gap between pharmacokinetics and clinical response. The knowledge of opioid metabolism is essential, particularly for older and complicated patients who receive multi…

Single-shot slightly off-axis digital holographic microscopy with add-on module based on beamsplitter cube

2019

Slightly off-axis digital holographic microscopy (SO-DHM) has recently emerged as a novel experimental arrangement for quantitative phase imaging (QPI). It offers improved capabilities in conventional on-axis and off-axis interferometric configurations. In this contribution, we report on a single-shot SO-DHM approach based on an add-on module adapted to the exit port of a regular microscope. The module employs a beamsplitter (BS) cube interferometer and includes, in addition, a Stokes lens (SL) for astigmatism compensation. Each recorded frame contains two fields of view (FOVs) of the sample, where each FOV is a hologram which is phase shifted by π rads with respect to the other. These two …
