The Use of the RETeval Portable Electroretinography Device for Low-Cost Screening: A Mini-Review.

Electroretinography (ERG) provides crucial insights into retinal function and the integrity of the visual pathways. However, ERG assessments classically require a complicated technical background with costly equipment. In addition, the placement of corneal or conjunctival electrodes is not always tolerated by the patients, which restricts the measurement for pediatric evaluations. In this short review, we give an overview of the use of the RETeval portable ERG device (LKC Technologies, Inc., Gaithersburg, MD, USA), a modern portable ERG device that can facilitate screening for diseases involving the retina and the optic nerve. We also review its potential to provide ocular biomarkers in systemic pathologies, such as Alzheimer's disease and central nervous system alterations, within the framework of oculomics.

Refractive results of photorefractive keratectomy comparing trans-PRK and PTK-PRK for correction of myopia and myopic astigmatism.

PURPOSE: To compare refractive outcomes after transepithelial photorefractive keratectomy (tPRK) and combined phototherapeutic keratectomy (PTK-PRK) procedure using two different excimer laser platforms for correction of myopia and myopic astigmatism. METHODS: In this retrospective multicenter study, we compared the results of two different PRK methods. The first group received a tPRK treatment with the Amaris750 excimer laser (Schwind eye-tech solutions). The second group received a combined PTK-PRK treatment with the MEL90 excimer laser (Carl Zeiss). Only healthy eyes with no previous surgery and a spherical equivalent (SE) of -1 to -8 diopters (D) were included. Preoperative spherical equivalent (SE), age, and sex were matched among the two groups. All treatments were performed by the same surgeon in different clinics. This study was approved by the local Ethics Committee (No. 2022-1980). RESULTS: We included 154 eyes of 86 patients in our study. There was no difference in predictability of SE between the two groups. Efficacy and safety indices were equally high in both groups. Similarly, no significant differences were seen in change of higher order aberrations (HOA) between the two groups (p > 0.05). No complications occurred. CONCLUSION: Both investigated methods provide safe and effective refractive results. The combination of PTK with PRK may be a suitable option to the already used one-step tPRK for the correction of myopia.

Refractive outcomes of small lenticule extraction (SMILE) Pro® with a 2 MHz femtosecond laser.

PURPOSE: To evaluate the initial visual outcomes of Small Incision Lenticule Extraction (SMILE) Pro® using a 2 MHz femtosecond laser (VisuMax 800, Carl Zeiss Meditec) and to assess the efficacy, safety, predictability, accuracy, and complication rate. METHODS: This retrospective analysis included eyes which underwent the SMILE Pro® procedure using VisuMax 800 femtosecond laser to correct myopia. All surgeries were performed by one surgeon (DB). Follow-up was conducted 3 months postoperatively to evaluate visual outcomes after neuroadaptation, corrected visual acuity (CDVA) and intra- and postoperative complications. RESULTS: One hundred and fifty-two eyes of 82 patients (mean age 31 ± 6 years) results at 3 months are presented. The mean spherical equivalent (SE) was - 4.44 ± 1.86 D preoperatively while -0.24 ± 0.32 D postoperatively. 99% of eyes achieved SE within ± 1.0 D of attempted correction and 91% were within ± 0.5 D. Efficacy index was 0.93 while the safety index was 1. No complications occurred intra- or postoperatively. No eyes lost more than 1 line of their preoperative CDVA. All highly myopic eyes (- 6.25 to - 10.00 D; n = 18) achieved 20/20 at 3 months postoperatively and were within 0.5 D from the attempted SE and no eyes lost more than 1 line of CDVA. CONCLUSION: The SMILE Pro® is a safe, efficient, and predictable procedure for the treatment of myopia and myopic astigmatism, with comparable results of conventional SMILE surgery. High myopic eyes achieve better results than low and moderate myopia. No complications were recorded in our patients.

Surgical outcomes of laser in situ keratomileusis (LASIK) in patients with stable systemic disease.

PURPOSE: To evaluate the surgical outcome in terms of safety, efficacy, predictability, and retreatment rate of LASIK surgery in patients with controlled systemic diseases in comparison with healthy individuals. METHODS: The retrospective study included data from 1936 eyes of 976 patients with stable systemic diseases who underwent LASIK surgery between January 2016 and June 2019. The safety, efficacy, predictability of the surgery, and retreatment rate were evaluated in comparison with a control group comprising 1951 patients. The study was approved by the local ethics committee and adhered to the principles of the Declaration of Helsinki. Statistical analysis was performed using R team and the level of statistical significance was set at p < 0.05. RESULTS: All treatment groups demonstrated high safety and efficacy indices after LASIK surgery. Furthermore, the study arms demonstrated comparable predictability and retreatment rates to the control group in nearly all cases. Retreatment rates were significantly higher in the rheumatoid arthritis group (p = 0.03), while safety indices were significantly lower in the hay fever group compared to the control group (p = 0.004). No intra- or postoperative sight-threatening complications were documented. CONCLUSION: Our findings suggest that selected patients with stable systemic conditions can safely undergo LASIK surgery and achieve comparable outcomes to healthy individuals. Further research is needed to better understand the treatment outcomes in this challenging patient population.

Influence of perfluorohexyloctane (Evotears®) on higher order aberrations.

PURPOSE: To prospectively assess the effect of regular application of perfluorohexyloctane (F6H8; Evotears®) on the tear film lipid layer, higher order aberrations (HOA) and the repeatability of measurements in healthy eyes. METHODS: This prospective clinical study included 104 eyes treated with F6H8 four times daily for four weeks (group A) and 101 eyes that served as controls (group B). Measurements were performed with the WASCA aberrometer (Carl Zeiss Meditec GmbH, Jena, Germany). Main outcome measurement in addition to subjective refraction were the root mean square values of HOA measured before and after the intervention. RESULTS: Regular use of F6H8 over a period of four weeks significantly increases HOA in healthy eyes (p < 0.05). In addition, the repeatability of measurement increases after the application of F6H8. CONCLUSION: F6H8 may be a suitable treatment option to improve the accuracy of refractive assessment, although it increases HOA. Further studies are needed to confirm the effect on HOA and the repeatability of measurement.

Egyptian Society of Liver Cancer Recommendation Guidelines for the Management of Hepatocellular Carcinoma.

Globally, hepatocellular carcinoma (HCC) is the fourth most common cause of death from cancer. The prevalence of this pathology, which has been on the rise in the last 30 years, has been predicted to continue increasing. HCC is the most common cause of cancer-related morbidity and mortality in Egypt and is also the most common cancer in males. Chronic liver diseases, including chronic hepatitis C, which is a primary health concern in Egypt, are considered major risk factors for HCC. However, HCC surveillance is recommended for patients with chronic hepatitis B virus (HBV) and liver cirrhosis; those above 40 with HBV but without cirrhosis; individuals with hepatitis D co-infection or a family history of HCC; and Nonalcoholic fatty liver disease (NAFLD) patients exhibiting significant fibrosis or cirrhosis. Several international guidelines aid physicians in the management of HCC. However, the availability and cost of diagnostic modalities and treatment options vary from one country to another. Therefore, the current guidelines aim to standardize the management of HCC in Egypt. The recommendations presented in this report represent the current management strategy at HCC treatment centers in Egypt. Recommendations were developed by an expert panel consisting of hepatologists, oncologists, gastroenterologists, surgeons, pathologists, and radiologists working under the umbrella of the Egyptian Society of Liver Cancer. The recommendations, which are based on the currently available local diagnostic aids and treatments in the country, include recommendations for future prospects.

Prognostic impact of MYD88 and TP53 mutations in diffuse large B Cell lymphoma.

Diffuse large B cell lymphoma (DLBCL) is the most common subtype of lymphoma. It is a highly heterogeneous lymphoid neoplasm, with variations in gene expression profiles and genetic alterations. MYD88 and TP53 genes are common to be expressed and mutated in DLBCL patients with controversy regarding their role in prognosis and survival. This study aims to determine the predictive and prognostic role of MYD88 and TP53 gene mutation in DLBCL. A prospective cohort study was conducted on 50 patients who were diagnosed with DLBCL and 30 healthy individuals to assess the sensitivity and specificity of MYD88 and TP53 genetic mutations. MYD88 and TP53 gene mutations were more sensitive, specific, and accurate in predicting overall mortality and disease progression in comparison with the international prognostic index. Mutant MYD88 and TP53 showed their prognostic importance for worse objective response rates and survival outcomes. Both mutant MYD88 and TP53 were associated with worse ORR. There was a significant statistical difference for both MYD88 and TP53 with regard to 2-year PFS and 2-year OS rate. Hence, both mutant MYD88 and TP53 can be used in predicting disease progression and overall mortality.

Repeatability of pupil diameter measurements using three different topography devices.

PURPOSE: To evaluate the intra- and inter-device repeatability of pupil diameter measurements using three different devices in patients prior to corneal refractive surgery. METHODS: We examined preoperative measurements from a total of 204 eyes (102 patients) scheduled for corneal refractive surgery at two private centers between July and December 2021. Three consecutive scans were performed with three different devices (Sirius anterior segment analyzer, Pentacam HR, IOLMaster 500) in the same session by the same examiner under standardized conditions. To assess the intra- and inter-device repeatability, we calculated the Intraclass Correlation Coefficient (ICC) and demonstrated results using Bland-Altman plots. RESULTS: The measurement accuracy (intra-device repeatability) of Sirius and IOLMaster was comparable (ICC = 0.64 and 0.61, respectively), with almost no statistically significant differences. Sirius showed the highest measurement accuracy among the three devices. Pentacam measurements resulted in lower precision, with an ICC of 0.09. The agreement between the pairs of devices (inter-device repeatability) was low (wide LoA ranges, Table 5). CONCLUSION: In this study, the intra-device repeatability of Sirius and IOLMaster was higher than that of the Pentacam, although it did not achieve an optimal level across all three devices. The three devices examined cannot be used interchangeably.

Pre- and postoperative angle kappa in MIOL patients after touch-up LASIK.

PURPOSE: To study the influence of angle kappa (κ) on visual acuity after implantation of a multifocal intraocular lens (MIOL) and consecutive "touch-up" corneal refractive surgery with Laser-in-situ-Keratomileusis (LASIK). METHODS: This retrospective multicenter study included patients who underwent MIOL surgery and consecutive LASIK (= Bioptics) in the period from 2016 to 2020 at Care Vision Refractive Centers in Germany. Our study was approved by the local ethics committee at the University in Duesseldorf (approval date: 23.04.2021) and conducted according to the tenets of the Declaration of Helsinki and Good Clinical Practices Guidelines. The pre- and post-operative κ of 548 eyes were measured using a Scheimpflug-based imaging system. Corrected distance visual acuity (CDVA) and the safety index (SI) were analyzed in relation with κ. For a more detailed analysis, the cohort was divided into pre-operative hyperopic and myopic patients to show group-specific differences. RESULTS: There was a significant decrease (p<0.001) in the magnitude of κ after MIOL implantation and Bioptics. However, there was almost no significant correlation of κ on CDVA and SI, pre- and postoperatively. CONCLUSION: A large κ is not a significant risk factor for poor visual acuity. Therefore, it is not a suitable clinical predictor of postoperative outcomes after a Bioptic procedure.

The influence of a mineral oil cationic nanoemulsion or perfluorohexyloctane on the tear film lipid layer and higher order aberrations.

PURPOSE: To prospectively assess the effect of a single and regular application of either a cationic nanoemulsion of mineral oil (CN) or perfluorohexyloctane (F6H8) on the lipid layer of the tear film and higher order aberrations (HOA) in patients with Dry Eye Disease (DED). METHODS: Fifty-seven patients with a lipid layer thickness (LLT) ≤ 75 interferometric colour units (ICU) were included in the study. In group A (20 patients) the effect of a single drop of F6H8 or CN on HOA and LLT was assessed immediately after application and up to two hours later. For long term effects (Group B) 37 patients applied CN or F6H8 five times a day for 12 weeks. Measurement of LLT, HOA, non-invasive-tear-break-up-time (NIBUT) and meibography were assessed prior to as well as at 4 weeks and 12 weeks after initiation of treatment. Our study is registered in the "German Clinical Trials Register" under the trial number: DRKS00028696. RESULTS: CN led to an increase of the LLT from 46.8 ± 16.9 ICU to 76.3 ± 23.5 ICU (p = 0.021) and to an increase of HOA from 0.43 ± 0.06 µm to 0.48 ± 0.08 µm immediately after application (p = 0.027). There was no correlation between the increase of LLT and HOA (r = -0.04; p = 0.90). In group B an increase of LLT was observed in the F6H8 group from 45.8 ± 8.8 ICU at baseline to 66.7 ± 19.5 ICU at 12 weeks (p = 0.002). No changes of HOA were measured throughout the observation period in group B. After 12 weeks CN increased NIBUT from 9.9 ± 5.3 seconds to 15.5 ± 5.6 seconds (p = 0.04). F6H8 increased NIBUT from 12.4 ± 5.9 seconds to 16.9 ± 4.7 seconds (p = 0.02) after 12 weeks. CONCLUSION: CN leads to a short-term increase in LLT and HOA, but only immediately after application. In contrast F6H8 does lead to an increase of LLT after regular long-term use but has no effect on HOA. The regular application of lipid-based products does not seem to decrease the quality of vision as measured in HOA. Instead, CN and F6H8, both are able to stabilize the tear film after regular application.

Pelvi-abdominal ACTINOMYCOSIS as a complication of long-term use of intrauterine device (IUD). The important role of imaging in diagnosis and follow-up.

ACTINOMYCOSIS is a rare chronic granulomatous disease caused by anaerobic filamentous gram-positive bacteria, the most common of which is Actinomyces israelii. Actinomycetes are commensal inhabitants of the oral cavity and gastrointestinal tract, but they may become pathogenic through invasion of breached or necrotic tissue. Pelviabdominal ACTINOMYCOSIS is uncommon and can mimic a variety of disease processes, including abdominal mass mimicking malignancy, acute abdomen, asthenia, and weight loss. We describe a 38-year-old woman who presented with acute abdominal pain and tenderness, as well as constitutional manifestations and elevated inflammatory markers. On initial computerized tomography (CT) and MRI, a large fluid collection underlining the anterior abdominal wall at the false pelvic cavity, as well as parietal peritoneal enhancement and smudging of the mesenteric fat and a bulky fibroid uterus with an implanted IUD, were identified. The ultrasound guided aspiration and anaerobic culture revealed positive growth for Actinomyces bacteria. An exploratory laparoscopy revealed extensive adhesions between the abdominal wall and the small intestine, as well as hyperemic and thickened peritoneum, and peritoneal biopsy confirmed ACTINOMYCOSIS. After the diagnosis was established, the IUD was removed and the patient was given Ceftriaxone 2 gm once daily for 6 weeks before switching to oral doxycycline 100 mg twice daily for another 3 months. A significant regression of the suprapubic fluid collection, and peritoneal-mesenteric changes were confirmed on follow-up. The case is discussed, and the relevant literature reviewed and analyzed.

Prognostic utility of lncRNAs (LINC00565 and LINC00641) as molecular markers in glioblastoma multiforme (GBM).

BACKGROUND AND AIM: Glioblastoma multiforme (GBM) is primary brain tumor grade IV characterized by fast cell proliferation, high mortality and morbidity and most lethal gliomas. Molecular approaches underlying its pathogenesis and progression with diagnostic and prognostic value have been an area of interest. Long-non coding RNAs (lncRNAs) aberrantly expressed in GBM have been recently studied. The aim is to investigate the clinical role of lncRNA565 and lncRNA641 in GBM patients. PATIENTS AND METHODS: Blood samples were withdrawn from 35 newly diagnosed GBM cases with 15 healthy individuals, then lncRNA565 and lncRNA641 expression were evaluated using real time-PCR. Their diagnostic efficacy was detected using receiver operating characteristic curve. Progression free survival (PFS) and overall survival (OS) were studied using Kaplan-Meier curves. RESULTS: lncRNAs expressions were increased significantly among GBM as compared to control group. Their expressions were correlated with clinico-pathological data and survival pattern for the studied GBM patients. Higher levels of both lncRNAs were correlated to worse performance status. Expression of lncRNA565 was increased with large tumor size (≥ 5 cm). Survival analysis showed that both investigated lncRNA were increased with worse PFS and OS. CONCLUSION: Expression of lncRNA565 and lncRNA641 in a liquid biopsy sample can be used as prognostic biomarker for GBM patients.

Resource Oriented Decision Making for Treatment of Metastatic Colorectal Cancer (mCRC) in a Lower-Middle Income Country: Egyptian Foundation of Medical Sciences (EFMS) Consensus Recommendations 2020.

PURPOSE: Colorectal cancer (CRC) is the third most commonly diagnosed cancer worldwide and the second cause of cancer related mortality. Treatment options for patients with metastatic CRC (mCRC) expanded during the last two decades, with introduction of new chemotherapeutic and targeted agents. Egypt is a lower middle-income country; Egyptian health care system is fragmented with wide diversity in drug availability and reimbursement policies across different health care providing facilities. We report the results of consensus recommendations for treatment of patients with metastatic colorectal cancer developed by Egyptian Foundation of Medical Sciences (EFMS), aiming to harmonize clinical practice through structured expert consensus-based recommendations consistent with the national status. EFMS recommendations could be utilized in other countries with similar economic status. METHODS: EFMS recommendations were developed using a modified Delphi process, with three rounds of voting till the final recommendations were approved. A non-systematic review of literature was conducted before generating the provisional statements. Content experts were asked to vote on some recommendations in two different resource groups (restricted resources and non-restricted resources). External review board of experts from a low income and lower-middle countries voted on the applicability of EFMS recommendations in their countries. RESULTS: The current recommendations highlighted the discrepancy in health care between restricted and non-restricted resources with expected survival loss and quality of life deterioration. Access to targeted agents in first line is very limited in governmental institutions, and no access to agents approved for third line in patients who failed oxaliplatin and irinotecan containing regimens for patients treated in restricted resource settings. CONCLUSION: Management of mCRC in developing countries is a challenge. The currently available resource-stratified guidelines developed by international cancer societies represent a valuable decision-making tool, adaptation to national status in each country based on healthcare system status is required.

Impact of TNF-α Gene Polymorphisms on Pancreatic and Non-Small Cell Lung Cancer-Induced Cachexia in Adult Egyptian Patients: A Focus on Pathogenic Trajectories.

BACKGROUND: Cachexia is a frequent syndrome in pancreatic and non-small cell lung (NSCL) cancer patients. The storm of cancer-induced inflammatory cytokines, in particular TNF-α, is a crucial pathogenic mechanism. Among the molecular alterations accused of cancer-induced cachexia, TNF-α 308 G/A (rs1800629) and -1031T/C (rs1799964) are single-nucleotide polymorphisms (SNPs) within the gene encoding this pro-inflammatory cytokine. Recent studies have demonstrated the crucial role of non-coding microRNAs (miRNAs) in pathogenesis of different diseases including cachexia. Moreover, the mechanistic cytokine signaling pathway of miR-155, as a TNF-α regulator, supports the involvement of SOCS1, TAB2, and Foxp3, which are direct targets of TNF-α gene. AIM: A case-control study (NCT04131478) was conducted primarily to determine the incidence of TNF-α 308 G/A (rs1800629) and -1031T/C (rs1799964) gene polymorphisms in adult Egyptian patients with local/advanced or metastatic pancreatic or NSCL cancer and investigate both as cachexia risk factors. The association of gene polymorphism with cachexia severity and the expression of miR-155 in cachectic patients were analyzed. A mechanistic investigation of the cytokine signaling pathway, involving SOCS1, TAB2, and Foxp3, was also performed. RESULTS: In both pancreatic and NSCL cancer cohorts, the mutant TNF-α variant of 308 G/A was positively associated with cachexia; on the contrary, that of 1031T/C was negatively associated with cachexia in the NSCL cancer patients. MiR-155 was higher in cachexia and in alignment with its severity in the cachectic group as compared with the non-cachectic group in both the pancreatic and NSCL cancer patients. Though TAB2 did not change to any significant extent in cachectic patients, the levels of SOCS1 and Foxp3 were significantly lower in the cachectic group as compared with the non-cachectic group. CONCLUSION: Carriers of the A allele 308 G/A gene and high miR-155 are at greater risk of cachexia in both the pancreatic and NSCL cancer patients; however, the mutant variant of 1031T/C gene is protective against cachexia in the NSCL cancer patients. Finally, high levels of miR-155 in the cachectic group lead to negative feedback inhibition of both SOCS1 and Foxp3 in both the pancreatic and NSCL cancer patients.

The effect of itraconazole on the clinical outcomes of patients with advanced non-small cell lung cancer receiving platinum-based chemotherapy: a randomized controlled study.

Itraconazole is an oral antifungal that has a been reported to have anticancer effect in non-small cell lung cancer (NSCLC) through inhibition of angiogenesis. The aim is to evaluate the effect of using itraconazole on the clinical outcome of metastatic NSCLC. This was a prospective randomized controlled open-label study conducted on 60 chemotherapy-naive metastatic NSCLC. Patients were simply randomized to either Control group who received platinum-based chemotherapy for a maximum of six cycles or Itraconazole group who received the same chemotherapy regimen in addition to itraconazole 200 mg daily for 21 days starting from day 1 in each cycle. Primary outcome was 1-year progression-free survival (PFS) while secondary outcomes included overall response rate (ORR), 1-year overall survival (OS) and tolerability. The two groups were comparable at baseline with no significant difference between groups regarding demographics and clinical characteristics. The ORR in Control group was 66.7% versus 90% in Itraconazole group (p value 0.028). There was a significant difference between groups regarding PFS where the mean 1-year PFS was 5.415 months in Control group versus 6.556 months in Itraconazole group (p value = 0.002). However, there was no significant difference between groups with respect to 1-year OS. All adverse effects reported were tolerable except for one patient who developed grade 2 cardiotoxicity in Itraconazole group requiring itraconazole discontinuation. Itraconazole use was beneficial in NSCLC in terms of 1-year PFS and ORR which was not reflected by improvement in 1-year OS.Clinical trial.gov registration number: NCT03664115, date of registration: September 10, 2018.

Pentoxifylline and vitamin E reduce the severity of radiotherapy-induced oral mucositis and dysphagia in head and neck cancer patients: a randomized, controlled study.

The purpose of this study was to assess the impact of pentoxifylline and vitamin E on the incidence and severity of radiotherapy-induced oral mucositis and dysphagia in head and neck cancer patients. This is a prospective, randomized, controlled study. Head and neck cancer patients receiving 30-35 radiotherapy fractions with or without concurrent chemotherapy excluding those intolerant to xanthines, with any bleeding tendency were included. Sixty patients were enrolled; 30 patients received radiotherapy (control group) and 30 patients received radiotherapy with pentoxifylline and vitamin E (intervention group). The incidence, severity, onset and duration of oral mucositis and/or dysphagia were assessed. Locoregional control, quality of life, need for hospitalization, radiotherapy breaks, and adverse events were recorded and compared between groups. Pentoxifylline and vitamin E combination did not affect the incidence or the onset of oral mucositis or dysphagia. After adjusting for age, the combination reduced the incidence of severe oral mucositis (p = 0.01) and dysphagia (p = 0.012). The combination decreased the duration of oral mucositis and dysphagia by 5 weeks (p = 0.002) and 4 weeks (p = 0.003), respectively. The study drugs reduced the need for hospitalization (p = 0.002) and for radiotherapy breaks (p = 0.002) with improvement of FOIS (p = 0.014), EQ-5D index (p = 0.009) and VAS score (p = 0.012). Pentoxifylline and vitamin E decreased the occurrence of dysgeusia (p = 0.026) and fatigue (p = 0.026) without compromising locoregional control. Pentoxifylline/vitamin E combination reduced the severity and duration of acute radiotherapy-induced oral mucositis and dysphagia in head and neck cancer patients.Trial registry ClinicalTrials.gov registration number: NCT02397486.

Doxorubicin-loaded nanoparticles for patients with advanced hepatocellular carcinoma after sorafenib treatment failure (RELIVE): a phase 3 randomised controlled trial.

BACKGROUND: Cytotoxic chemotherapy is generally ineffective in patients with hepatocellular carcinoma. We assessed the intravenous perfusion of doxorubicin-loaded nanoparticles in patients with hepatocellular carcinoma in whom previous sorafenib therapy had failed. METHODS: We did a multicentre, open-label, randomised, controlled phase 3 trial at 70 sites in 11 countries. Patients with hepatocellular carcinoma with one or more previous systemic therapies, including sorafenib, were randomly assigned to receive 30 mg/m2 doxorubicin-loaded nanoparticles (30 mg/m2 group), 20 mg/m2 doxorubicin-loaded nanoparticles (20 mg/m2 group), or standard care using a computer-generated randomisation list prepared by the funder and stratified by geographic region. Patients in the experimental groups received perfusion of the drug every 4 weeks and those in the control group received any systemic anticancer therapy (except sorafenib) as per investigator decision. The primary endpoint was overall survival in the intention-to-treat population. Safety was assessed in the population of patients who received at least one dose of their assigned treatment. This trial is registered with ClinicalTrials.gov, number NCT01655693. FINDINGS: Between June 15, 2012, and Jan 27, 2017, 541 patients were screened, of whom 144 were excluded and 397 were randomly assigned to one of the groups (133 to the 30 mg/m2 group; 130 to the 20 mg/m2 group; and 134 to the control group). Median follow-up was 22·7 months (IQR 11·2-34·9). After pooling the doxorubicin groups for the efficacy analysis, median overall survival was 9·1 months (95% CI 8·1-10·4) in the pooled doxorubicin-loaded nanoparticles group and 9·0 months (7·1-11·8) in the control group (HR 1·00 [95% CI 0·78-1·28], two-sided p=0·99). 227 (94%) of 242 patients who received doxorubicin-loaded nanoparticles and 100 (75%) of 134 patients in the control group had at least one treatment-emergent adverse event. The most common drug-related grade 3 or 4 treatment-emergent adverse events were neutropenia (25 [10%] of 242 treated with doxorubicin-loaded nanoparticles and eight [6%] of 134 in the control group), asthenia (six [2%] and four [3%]), and thrombocytopenia (three [1%] and ten [7%]). Six (2%) patients treated with doxorubicin-loaded nanoparticles and one (1%) of those in the control group were deemed by investigators to have had a drug-related death. Serious adverse events occurred in 74 (31%) patients who received doxorubicin-loaded nanoparticles and 48 (36%) in the control group. INTERPRETATION: Doxorubicin-loaded nanoparticles did not improve overall survival for patients with hepatocellular carcinoma in whom previous sorafenib treatment had failed. FUNDING: Onxeo.

L-Carnosine protects against Oxaliplatin-induced peripheral neuropathy in colorectal cancer patients: A perspective on targeting Nrf-2 and NF-κB pathways.

BACKGROUND: Chemotherapy-induced peripheral neuropathy is a common side effect afflicting cancer patients treated with oxalipatin based chemotherapy. AIM: The study investigated the potential prophylactic effect of L-carnosine against acute oxaliplatin neurotoxicity in colorectal cancer patients with emphasis on the redox (Nrf-2, MDA), inflammatory (NF-κB, TNF-α), and apoptotic (caspase-3) parameters. METHODS: In this pilot study, 65 patients were recruited using a prospective randomized controlled study design and enrolled randomly into two arms; Arm A, 31 patients received FOLFOX-6 regimen (oxaliplatin, 5FU & leucovorin) and Arm B, 34 patients received FOLFOX-6 regimen and daily oral L-carnosine (500 mg) along the treatment period. Patients were followed up for three months, then both arms were analyzed for neuropathy incidence/grade and any additional toxicities according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTC version 4). RESULTS: The neuropathy grading evaluation of Arm B vs Arm A revealed that 17 patients (56.7%) vs 11 patients (35.5%) suffered grade 1, one patient (3.3%) vs 19 patients (61.3%) suffered grade 2, while 12 patients (40%) vs one patient (3.2%) were normal. In arm B, the addition of L-carnosine decreased significantly the levels/activity of NF-κB (27%) and TNF-α (36.6%); this anti-inflammatory effect entailed also its anti-oxidative and anti-apoptotic effects, thus MDA level (51.8%) and caspase-3 activity (49%) were also reduced, whereas Nrf-2 was increased (38.7%) as compared to Arm A. In both arms a significant correlation was only evident between TNF-α and the neuropathy grading score (P < .03); the correlation analysis was significantly positive between NF-κB and both Nrf-2 and caspase 3. CONCLUSION: L-Carnosine exerted a neuroprotective effect against oxaliplatin-induced peripheral neuropathy in colorectal cancer patients by targeting Nrf-2 and NF-κB pathways.

The Association Between the FTO rs9939609 Variant and Malignant Pleural Mesothelioma Risk: A Case-Control Study.

AIMS: Despite the established link between malignant pleural mesothelioma (MPM) and asbestos exposure, genetic risk factors may play a key role in MPM pathogenesis. The rs9939609 polymorphism in the FTO gene has recently been implicated as a risk factor for some types of cancer, such as breast, pancreatic, and prostate cancers. FTO variation is associated with altered adipocytokine expression and oxidative stress inflammation, which may influence asbestos mediated-carcinogenesis. This is the first study to investigate a possible association between this polymorphism and MPM risk. MATERIALS AND METHODS: FTO rs9939609 (T >A) genotypes were screened using a TaqMan® Genotyping Assay in a total of 235 Egyptian subjects (86 MPM patients versus 149 controls). The chi-square test and logistic regression were used to evaluate the association between the candidate variant and MPM risk using a case-control design. RESULTS: In the additive genetic model, the AT and AA genotypes were associated with a 2.48-fold (95% confidence intervals [CI] = 1.04-5.92, p = 0.04) and a 3.46-fold (95% CI = 0.99-12.01, p = 0.051) increase in the odds of developing MPM, respectively, when compared to the TT genotype after adjustment for body mass index, age, and gender. Additionally, in the dominant genetic model AT/AA genotypes were associated with a 2.63-fold increase in the odds of developing MPM (95% CI = 1.13-6.12, p = 0.025). CONCLUSIONS: The present study shows for the first time that rs9939609 polymorphism in the FTO gene may be a genetic risk factor for MPM. This study highlights the association of this genetic polymorphism with cancer susceptibility, and therefore, it should be investigated in various other populations, in relation to different types of cancer, and with larger sample sizes.

A prospective randomized controlled study of cisplatin versus carboplatin-based regimen in advanced squamous nonsmall cell lung cancer.

BACKGROUND: The use of cisplatin (Cis) versus carboplatin (Carb) in the treatment of advanced nonsmall cell lung cancer (NSCLC) is controversial. The aim of the study was to compare the safety and efficacy of Cis versus Carb in squamous NSCLC. PATIENTS AND METHODS: A prospective, randomized, controlled, open-label study was conducted on advanced squamous NSCLC patients who were randomly assigned to receive Cis (40 mg/m 2 [day 1 and day 8]) or Carb (area under the curve = 5 [day 1]) combined with gemcitabine [Gem] (1000 mg/m 2 [day 1 and day 8]) of a 3-week schedule for six cycles. Study objectives were a radiological response after three cycles and six cycles, 1-year progression-free survival (PFS), 1-year overall survival (OS), and quality of life (QOL) assessment using functional assessment of cancer therapy-lung at baseline, after three cycles, and after six cycles. STATISTICAL ANALYSIS: Statistical analysis was done using Statistical Package for Social Science version 15. A P < 0.05 was considered statistically significant. RESULTS: Seventy-one patients were enrolled (Gem/Cis group [n = 36], Gem/Carb group [n = 35]). Response rates were comparable in both arms. Nonsignificant differences were found regarding 1-year PFS (P = 0.308) and 1-year OS (P = 0.929) between the two groups. Neutropenia was significantly higher in Gem/Carb group, while vomiting and ototoxicity were significantly higher in Gem/Cis group. The effect on QOL was similar in both groups. CONCLUSION: Cis and Carb have similar efficacy, tolerability, and effect on QOL and both can be used as a first-line treatment of squamous NSCLC.
