RESUMEN

Smoking is recognized as the major cause of lung cancer. Healthcare professionals play an important role in lung cancer prevention policies, as they act as a source of guidance for patients and advocates. The following survey evaluated prevalence, knowledge, and attitudes toward tobacco smoking among a sample of workers in "IRCCS Istituto Tumori "Giovanni Paolo II" of Bari, an Italian cancer hospital. An anonymous questionnaire was completed by 104 healthcare professionals to collect personal and occupational data about smoking status, knowledge about the harms of smoking, current legislation in place, Second-Hand Smoke (SHS) awareness, and, for ex-smokers, the reasons for quitting. Among participants, 17.8% were current smokers, 26.2% former smokers, and 56% never smoked. Only 40% acknowledged that the smoking ban is generally respected, and 63.2% reported that they smoke during working hours. Most of the participants perceived tobacco control policy as an efficient way to protect public health. Currently, the implementation of Italian anti-smoking legislation has so far improved neither smoking cessation rates nor the will to quit smoking completely. Our experience highlights that to date the anti-smoking strategies have limited efficacy even in a cancer center; in fact, there is still a large prevalence of smokers among hospital personnel. Therefore, it is strongly suggested that interventions be shared with all healthcare workers, specifically aimed at developing a culture of health promotion.

RESUMEN

MicroRNAs (miRNAs) are small non-coding RNAs that control the expression of many target messenger RNAs (mRNAs) involved in normal cell functions (differentiation, proliferation and apoptosis). Consequently their aberrant expression and/or functions are related to pathogenesis of many human diseases including cancers. Haematopoiesis is a highly regulated process controlled by a complex network of molecular mechanisms that simultaneously regulate commitment, differentiation, proliferation, and apoptosis of hematopoietic stem cells (HSC). Alterations on this network could affect the normal haematopoiesis, leading to the development of haematological malignancies such as lymphomas. The incidence of lymphomas is rising and a significant proportion of patients are refractory to standard therapies. Accurate diagnosis, prognosis and therapy still require additional markers to be used for diagnostic and prognostic purpose and evaluation of clinical outcome. The dysregulated expression or function of miRNAs in various types of lymphomas has been associated with lymphoma pathogenesis. Indeed, many recent findings suggest that almost all lymphomas seem to have a distinct and specific miRNA profile and some miRNAs are related to therapy resistance or have a distinct kinetics during therapy. MiRNAs are easily detectable in fresh or paraffin-embedded diagnostic tissue and serum where they are highly stable and quantifiable within the diagnostic laboratory at each consultation. Accordingly they could be specific biomarkers for lymphoma diagnosis, as well as useful for evaluating prognosis or disease response to the therapy, especially for evaluation of early relapse detection and for greatly assisting clinical decisions making. Here we summarize the current knowledge on the role of miRNAs in normal and aberrant lymphopoiesis in order to highlight their clinical value as specific diagnosis and prognosis markers of lymphoid malignancies or for prediction of therapy response. Finally, we discuss their controversial therapeutic role and future applications in therapy by modulating miRNA.

RESUMEN

This article investigates the effects of tobacco control policies on smoking initiation, cessation and prevalence by examining the papers published in the last 5 years. Twenty-one articles have been selected by two authors and sorted by four types of tobacco control: tobacco prices, anti-smoking campaigns for young people, mass media intervention and public smoking bans. Price/tax increase has deterrent effect on smoking initiation but does not promote smoking cessation; intervention on young people could reduce the smoking initiation if carried out at an early age and if acted on social skills and with peer-led approach, as opposed to restraining measures which hare generally easily circumvented by young people. The mass media campaigns showed positive effect on attempts to quit among smokers if carried forward over time and by involving multiple communication channels (TV, internet, radio). The bans in public have little effect on smoking cessation but could improve the overall well-being of non-smokers. Heterogeneous results have been described by different studies probably because of different research methodologies, cultural aspects and the really effective implementation of the rules for each country. In conclusion, comprehensive tobacco control interventions to reduce smoking prevalence and modify the smoking behavior are recommended. Moreover, the use of e-cigarettes and heat-not-burn (HnB) products, as possible helping tool for smoke cessation, currently remains controversial.

RESUMEN

BACKGROUND: Second-line immunotherapy (IO) has shown an overall survival benefit. However, only 18% to 20% of patients with advanced non-small-cell lung cancer (aNSCLC) will respond, with a median progression-free survival (PFS) of 2 to 4 months. Thus, biomarkers to select those patients most likely to benefit from IO are greatly needed. PATIENTS AND METHODS: We conducted a retrospective analysis of 154 patients with aNSCLC who had received anti-programmed cell death 1 therapy as second line or further treatment. We assessed the absolute neutrophil, lymphocyte, monocyte, and eosinophil counts at baseline (T0) and the second (T1) and third (T2) cycles. The neutrophil/lymphocyte ratio (NLR), derived-NLR (dNLR), lymphocyte/monocyte ratio (LMR), and their percentage of change at T1 and T2 compared with T0 were evaluated. The clinical characteristics and lactate dehydrogenase (LDH) level were also considered. Univariate and multivariate analyses were performed. Significant biomarkers for PFS on multivariate analysis were combined in a prognostic score. RESULTS: For overall survival, the negative prognostic biomarkers were Eastern Cooperative Oncology Group (ECOG) performance status (PS) 2, NLR at T0, and dNLR at T1; the LMR at T0, T1, and T2 was identified as a positive prognostic biomarker. For PFS, the negative prognostic biomarkers were ECOG PS 2, liver metastases, NLR at T0, dNLR at T1 and T2, and ≥ 30% increase of NLR from T0 to T1; the positive prognostic biomarkers were heavy smoking, LDH, and LMR at T2. The ≥ 30% increase of LMR from T0 to T1 and T0 to T2 correlated with the overall response rate. A prognostic score (EPSILoN score; smoking, ECOG PS, liver metastases, LDH, NLR) identified 3 prognostic groups (median PFS, 10.2, 4.9, and 1.7 months, respectively; P < .001). CONCLUSIONS: The EPSILoN score combines 5 baseline clinical and blood biomarkers and can help to identify patients with aNSCLC who will most likely benefit from second-line IO. Further studies are warranted.

RESUMEN

BACKGROUND: In Europe the prevalence of tobacco use in adults and adolescents is among the highest within the WHO regions. Many resources have been allocated toward the prevention and support for smoking cessation. However, the implemented strategies in Europe have not been systematically evaluated. METHODS: A systematic literature review was carried out to identify studies that analyzed the efficacy of the main smoking-prevention campaigns conducted in Europe. PRISMA guidelines were used to systematically review and extract data. RESULTS: A total of 24 studies meeting inclusion criteria were identified. Each article was thoroughly reviewed and evaluated for quality, design, and methodology, with reference to the main areas of intervention: school (8); mass media (4) and technological tools (4); smoke-free environments (3); packaging (2) and taxes (3). The school programmes focusing on building skills to recognize and resist negative influences, the intensive use of media and technological equipments, health warnings and excise taxes have showed to be effective tools in reducing the tobacco use. CONCLUSIONS: Intervention programmes to implement tobacco control policies and smoking cessation are active in many European countries. However, these programmes need to be constantly sustained to achieve a long term efficacy.

RESUMEN

OBJECTIVES: Considering the frequent expression of somatostatine receptors, we designed the G04.2011 trial to investigate the efficacy of the somatostatine analogue lanreotide in maintenance for SCLC patients after response to standard treatment. MATERIALS AND METHODS: A multicenter, randomized, phase 3 trial was conducted in SCLC expressing somatostatine receptors at baseline Octreoscan, responding after platinum-based chemotherapy with/without radiotherapy. Patients were randomized 1:1 to receive maintenance lanreotide 120 mg subcutaneously every 28 days, up to 1 year or progression versus observation. Randomization was stratified according to stage (limited/extended, LD/ED). The primary end-point was progression-free survival (PFS). Secondary endpoints were overall survival (OS) and safety. RESULTS: Seventy-one patients were randomly assigned (39 to lanreotide, 32 to observation) in 9 Italian institutions. Median PFS was 3.6 (95% CI 3.2-3.9) with lanreotide versus 2.3 months (95% CI 1.7-2.9) with observation (HR 1.51, 95% CI 0.90-2.50; P = 0.11). Stage was an independent predictor for PFS (HR 3.14, 95% CI 1.77-5.57; P < 0.0001). Median PFS was 7.0 (95% CI <1-13.5) with lanreotide versus 3.8 months (95% CI <1-8.6) with observation in LD (P = 0.21), and 3.0 (95% CI 2.2-3.8) versus 2.2 (95% 1.7-2.7) in ED (P = 0.19). Median OS was 9.5 (95% CI 4.8-14.3) with lanreotide versus 4.7 months (95% CI <1-16.6) with observation (P = 0.47). Treatment-related adverse events occurred in 28% of patients with lanreotide (grade 3 in two patients). CONCLUSION: Although survival outcomes were not significantly prolonged with lanreotide as a maintenance in SCLC expressing somatostatin receptors after response to standard treatment, lanreotide showed a slight PFS benefit in LD SCLC deserving further investigations.

RESUMEN

INTRODUCTION: Contract research organization (CRO) support is largely included in clinical trial management, although its effect in terms of time savings and benefit has not yet been quantified. We performed a retrospective multicenter analysis of lung cancer trials to explore differences in term of trial activation timelines and accrual for studies with and without CRO involvement. MATERIALS AND METHODS: Results regarding study timelines from feasibility data to first patient enrollment were collected from 7 Italian thoracic oncology departments. The final accruals (screened/enrolled patients) are reported. We considered CRO/sponsor-administered and CRO-free trials according to who was responsible for the management of the crucial setup phases. RESULTS: Of 113 trials, 62 (54.9%) were CRO-administered, 34 (30.1%) were sponsor-administered, and 17 (15.0%) were CRO-free. The median time from feasibility invitation to documentation obtainment was 151 days in the CRO-administered trials versus 128 in the sponsor-administered and 120 in the CRO-free trials. The time from document submission to contract signature was 142 days in the CRO-administered versus 128 in the sponsor-administered and 132 in the CRO-free trials. The time from global accrual opening to first patient enrollment was 247 days for the CRO-administered versus 194 in the sponsor-administered and 151 in the CRO-free trials. No significant differences were observed in terms of the median overall timeline: 21 months in the CRO-administered, 15 in the sponsor-administered, and 18 months in the CRO-free studies (P = .29). CONCLUSION: Although no statistically significant differences were identified, the results of our analysis support the idea that bureaucratic procedures might require more time in CRO-administered trials than in sponsor-administered and CRO-free studies. This bureaucratic delay could negatively affect Italian patients' screening and enrollment compared with other countries.
