Quantitative experiments to explain the change of seasons

The science education literature shows that students have difficulty understanding what causes the seasons. Incorrect explanations are often due to a lack of knowledge about the physical mechanisms underlying this phenomenon. To address this, we present a module in which the students engage in quantitative measurements with a photovoltaic panel to explain changes to the sunray flow on Earth’s surface over the year. The activities also provide examples of energy transfers between the incoming radiation and the environment to introduce basic features of Earth’s climate. The module was evaluated with 45 secondary school students (aged 17–18) and a pre-/posttest research design. Analysis of students’ learning outcomes supports the effectiveness of the proposed activities

EGFR status and prognosis of patients with locally advanced head and neck cancer treated with chemoradiotherapy

Overexpression of epidermal growth factor receptor (EGFR) is related to poor prognosis in patients with head and neck cancer (HNC) treated with surgery or radiotherapy. We assessed the relationship between EGFR status and outcome in patients treated with concurrent chemoradiotherapy

Patients with cancer and hospital admissions: Disease trajectory and strategic choices

Objectives: Hospital admission (HA) in cancer history is a common, repeated and frequently unplanned event. The emergency departments (EDs) and the oncological outpatient service (OOS) are the ordinary way of entry. We studied the reasons of admission, pathways of access and discharge and prognostic factors in a population of admitted patients with cancer. Methods: The health records of the admitted patients in the oncological ward of a referral hospital in a 6-month period were retrieved and analysed. The characteristics of those admitted in the last 3 months of life were compared with the other group. Results: Among the 147 HA, 79.5% were unplanned, 48.9% passing through the ED and 30.6% through the OOS; 56.5% were due to cancer-related symptoms; 50.3% occurred in the last 3 months of life. Median overall survival was 90 days (95% IC 53.1-126.9). Independent prognostic factors for survival were: being admitted for symptoms, referral through the ED and not being discharged at home. Conclusions: Hospital is a turning point in the cancer care pathway. Patients needing HA have a dismal prognosis, half of them being in the last 3 months of life. This group can be identified using universally available variables

A phase II, open-label, single-arm trial of carboplatin plus etoposide with bevacizumab and atezolizumab in patients with extended-stage small-cell lung cancer (CeLEBrATE study): background, design and rationale

Based on improved survival from the addition of PD-L1 inhibitors in phase III trials, the combination of immunotherapy and platinum-doublet chemotherapy has become the new standard treatment for extended-stage small-cell lung cancer (ES-SCLC). Furthermore, the antiangiogenetic agent bevacizumab showed a longer progression-free survival by targeting VEGF that has pleiotropic effects, including immunosuppressive ones. We, therefore, hypothesized that targeting angiogenesis would improve the efficacy of chemoimmunotherapy. The CeLEBrATE trial is an open-label, multicenter, phase II study designed to assess the efficacy and safety of the combination of carboplatin and etoposide plus bevacizumab and atezolizumab in treatment-naive patients with ES-SCLC. The primary end point is overall survival rate at 1 year, while secondary end points include overall response rate, progression-free survival and toxicity

Pemetrexed versus pemetrexed and carboplatin as second-line chemotherapy in advanced non-small-cell lung cancer: Results of the GOIRC 02-2006 randomized phase II study and pooled analysis with the NVALT7 trial

Presented at the 47th Annual Meeting of the American Society of Clinical Oncology, Chicago, June 3-7, 2011; 14th World Conference on Lung Cancer, Amsterdam, the Netherlands, July 3-7, 2011; and 13th National Congress of Medical Oncology, Bologna, Italy, November 5-7, 2011.Purpose: To compare efficacy of pemetrexed versus pemetrexed plus carboplatin in pretreated patients with advanced non–small-cell lung cancer (NSCLC). Patients and Methods: Patients with advanced NSCLC, in progression during or after first-line platinum-based chemotherapy, were randomly assigned to receive pemetrexed (arm A) or pemetrexed plus carboplatin (arm B). Primary end point was progression-free survival (PFS). A preplanned pooled analysis of the results of this study with those of the NVALT7 study was carried out to assess the impact of carboplatin added to pemetrexed in terms of overall survival (OS). Results: From July 2007 to October 2009, 239 patients (arm A, n _ 120; arm B, n _ 119) were enrolled. Median PFS was 3.6 months for arm A versus 3.5 months for arm B (hazard ratio [HR], 1.05; 95% CI, 0.81 to 1.36; P _ .706). No statistically significant differences in response rate, OS, or toxicity were observed. A total of 479 patients were included in the pooled analysis. OS was not improved by the addition of carboplatin to pemetrexed (HR, 90; 95% CI, 0.74 to 1.10; P _ .316; P heterogeneity _ .495). In the subgroup analyses, the addition of carboplatin to pemetrexed in patients with squamous tumors led to a statistically significant improvement in OS from 5.4 to 9 months (adjusted HR, 0.58; 95% CI, 0.37 to 0.91; P interaction test _ .039). Conclusion: Second-line treatment of advanced NSCLC with pemetrexed plus carboplatin does not improve survival outcomes as compared with single-agent pemetrexed. The benefit observed with carboplatin addition in squamous tumors may warrant further investigation.Andrea Ardizzoni, Marcello Tiseo, Luca Boni, Andrew D.

Final results of the SENECA (SEcond line NintEdanib in non-small cell lung CAncer) trial

Objectives: Despite the scant docetaxel's tolerability, second-line association with nintedanib still represents a standard-of-care for non-squamous non-small cell lung cancer (nsNSCLC), giving to rapidly-progressing patients the greatest survival advantage. The SENECA trial is a phase IIb, open-label, study evaluating whether nintedanib/docetaxel can be equally effective and safe regardless docetaxel schedule.Materials and Methods: Recurrent nsNSCLC patients were stratified into cohort 1 and 2, according to relapse-time (within or over 3 months) from end of first-line chemotherapy. They were treated with docetaxel (T1: 33 mg/mq on days 1 and 8 in a 21-days cycle; T2: 75 mg/mq q3wks) plus nintedanib, allowing maintenance in case of disease-control. Primary endpoint was progression-free survival (PFS) by investigator's assessment; secondary endpoints: overall survival (OS), safety and quality-of-life.Results: Between January 2016-April 2018, 212 patients were evaluated: 30 resulted screening-failures, 12 were excluded for lack of compliance. According to investigator's choice, 85 patients received T1 docetaxel and 85 T2; 138 (81.2%) were stratified in C1, 32 (18.8%) in C2, with a median relapse-time of 0.54 and 9.29 months, respectively. Baseline characteristics were balanced between groups. After 35.5 months follow-up, no survival differences appear between cohorts and treatments; toxicity seems to be slightly higher in T2, especially for chemotherapy-related events. Perception of quality-of-life remains stable and docetaxel schedule doesn't modify patients' load.Conclusion: The SENECA trial confirms efficacy of second-line nintedanib/docetaxel for nsNSCLC, regardless time of recurrence and docetaxel schedule; higher toxicities for q3wks docetaxel, without alterations in quality-of-life, have been described, underling the possibility, adopting the weekly schedule, to maintain efficacy with better tolerability
