RESUMEN

Graphene and related 2D material (GRM) thin films consist of 3D assembly of billions of 2D nanosheets randomly distributed and interacting via van der Waals forces. Their complexity and the multiscale nature yield a wide variety of electrical characteristics ranging from doped semiconductor to glassy metals depending on the crystalline quality of the nanosheets, their specific structural organization ant the operating temperature. Here, the charge transport (CT) mechanisms are studied that are occurring in GRM thin films near the metal-insulator transition (MIT) highlighting the role of defect density and local arrangement of the nanosheets. Two prototypical nanosheet types are compared, i.e., 2D reduced graphene oxide and few-layer-thick electrochemically exfoliated graphene flakes, forming thin films with comparable composition, morphology and room temperature conductivity, but different defect density and crystallinity. By investigating their structure, morphology, and the dependence of their electrical conductivity on temperature, noise and magnetic-field, a general model is developed describing the multiscale nature of CT in GRM thin films in terms of hopping among mesoscopic bricks, i.e., grains. The results suggest a general approach to describe disordered van der Waals thin films.

RESUMEN

The combination of perioperative chemotherapy plus complete surgical resection is currently accounted as the first-choice strategy in patients with locally advanced Gastric Cancer (LAGC). Nevertheless, the partial response rate makes it necessary to search biological parameters useful to select patients who would benefit most from neoadjuvant chemotherapy (NAD-CT). We performed a retrospective analysis on a cohort of 65 LAGC cases, EBV negative and without MMR defect, submitted to perioperative chemotherapy plus surgical resection. We evaluated the neutrophil-lymphocytes ratio (NLR) in peripheral blood, the TILs density (reported as CD4/CD8 tissue ratio) and PD-L1 expression by immunohistochemistry on bioptic tissues before the treatment. Results were correlated with the biological features, histological response (TRG) and clinical outcome (PFS and OS). We found that NLR, TILs and PD-L1 expression showed a significant correlation with TNM stage, lymphovascular invasion and response to NAD-CT (TRG). Correlating the NLR, TILs and PD-L1 expression with PFS and OS, we found that patients with lower NLR levels (< 2.5 ratio), lower TILs (< 0.2 ratio) and higher PD-L1 level (CPS ≥ 1) had a significantly better PFS and OS than those with higher NLR, higher TILs and lower PD-L1 expression (p < 0.0001). Multivariate and multiple regression analyses confirmed the predictive and prognostic role of all three parameters, especially when all three parameters are combined. Our study demonstrated that pre-treatment NLR, TILs and PD-L1 expression are predictive and prognostic parameters in NAD-CT-treated LAGC suggesting a pivotal role of the systemic and tumor microenvironment immunological profile in the response to chemotherapy.

RESUMEN

BACKGROUND: This Phase 1b/2 study evaluated tepotinib, a highly selective MET inhibitor, in US/European patients with sorafenib pretreated advanced hepatocellular carcinoma (aHCC) with MET overexpression. METHODS: Eligible adults had aHCC, progression after ≥4 weeks of sorafenib, and, for Phase 2 only, MET overexpression. Tepotinib was administered once daily at 300 or 500 mg in Phase 1b ('3 + 3' design), and at the recommended Phase 2 dose (RP2D) in Phase 2. Primary endpoints were dose-liming toxicities (DLTs; Phase 1b) and 12-week investigator-assessed progression-free survival (PFS; Phase 2). RESULTS: In Phase 1b (n = 17), no DLTs occurred and the RP2D was confirmed as 500 mg. In Phase 2 (n = 49), the primary endpoint was met: 12-week PFS was 63.3% (90% CI: 50.5-74.7), which was significantly greater than the predefined null hypothesis of ≤15% (one-sided binomial exact test: P < 0.0001). Median time to progression was 4 months. In Phase 2, 28.6% of patients had treatment-related Grade ≥3 adverse events, including peripheral oedema and lipase increase (both 6.1%). CONCLUSIONS: Tepotinib was generally well tolerated and the RP2D (500 mg) showed promising efficacy and, therefore, a positive benefit-risk balance in sorafenib pretreated aHCC with MET overexpression. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02115373.

RESUMEN

Aim: To help to remove misperception of an appropriate position of trifluridine/tipiracil (FTD/TPI) in the treatment of metastatic colorectal cancer. Materials & methods: The RAND Corporation/UCLA Appropriateness Method was used by a panel of Italian experts to develop recommendations concerning daily practice with FTD/TPI. Forty-three clinical scenarios were discussed in two rounds and the resulting statements were rated as appropriate, uncertain or inappropriate, according to the median score. Results: Several topics were dealt with, covering the profile of eligible patients, therapeutic options beyond the second line, the practice of treatment with FTD/TPI, evaluation and efficacy and toxicity, as well as costs and compliance. Conclusion: FTD/TPI is an important therapeutic resource in refractory metastatic colorectal cancer that combines manageability and safety.

RESUMEN

The international PRECONNECT Phase IIIb study demonstrated safety and efficacy of trifluridine/tipiracil in the management of patients with metastatic colorectal cancer. Post-hoc analyses in a national context are important because of the differences in disease management across countries. Post-hoc safety and efficacy analyses in the PRECONNECT Italian patient subset were conducted. Patients' quality of life was assessed from baseline to end of treatment. In Italy, 161 patients were enrolled. The median age was 64 years, with a performance status of 0-1. The most common hematological drug-related adverse events ≥grade 3 were neutropenia (41.0%) and anemia (13.7%). The median progression-free survival was reached at 3.0 months, with a disease control rate of 28.6%. The Quality of Life Questionnaire Core 30 score improved in 25.4% of the patients. Safety, efficacy and quality of life results confirmed trifluridine/tipiracil as a feasible and favorable treatment option for metastatic colorectal cancer patients.


Lay abstract PRECONNECT is an international study demonstrating the efficacy and tolerability of the drug combination trifluridine/tipiracil in adult patients with metastatic colorectal cancer treated in everyday clinical practice. For this publication, the authors conducted an analysis performed on the 161 Italian patients enrolled in this study. These kinds of analyses are important because of the differences that may arise across different countries. The most common contraindications were not dangerous to health. Furthermore, 3 months from beginning the medication, half of the patients did not show a worsening of the disease and quality of life during treatment was maintained. Clinical trial registration: NCT03306394 (ClinicalTrials.gov).

RESUMEN

BACKGROUND: In the phase III CORRECT trial, regorafenib significantly improved survival in treatment-refractory metastatic colorectal cancer (mCRC). The CONSIGN study was designed to further characterize regorafenib safety and allow patients access to regorafenib before market authorization. METHODS: This prospective, single-arm study enrolled patients in 25 countries at 186 sites. Patients with treatment-refractory mCRC and an Eastern Cooperative Oncology Group performance status (ECOG PS) ≤1 received regorafenib 160 mg once daily for the first 3 weeks of each 4-week cycle. The primary endpoint was safety. Progression-free survival (PFS) per investigator assessment was the only efficacy evaluation. RESULTS: In total, 2,872 patients were assigned to treatment and 2,864 were treated. Median age was 62 years, ECOG PS 0/1 was 47%/53%, and 74% had received at least three prior regimens for metastatic disease. Median treatment duration was three cycles. Treatment-emergent adverse events (TEAEs) led to dose reduction in 46% of patients. Regorafenib-related TEAEs led to treatment discontinuation in 9%. Grade 5 regorafenib-related TEAEs occurred in <1%. The most common grade ≥3 regorafenib-related TEAEs were hypertension (15%), hand-foot skin reaction (14%), fatigue (13%), diarrhea (5%), and hypophosphatemia (5%). Treatment-emergent grade 3-4 laboratory toxicities included alanine aminotransferase (6%), aspartate aminotransferase (7%), and bilirubin (13%). Ongoing monitoring identified one nonfatal case of regorafenib-related severe drug-induced liver injury per DILI Working Group criteria. Median PFS (95% confidence interval [CI]) was 2.7 months (2.6-2.7). CONCLUSION: In CONSIGN, the frequency and severity of TEAEs were consistent with the known safety profile of regorafenib. PFS was similar to reports of phase III trials. ClinicalTrials.gov: NCT01538680. IMPLICATIONS FOR PRACTICE: Patients with metastatic colorectal cancer (mCRC) who fail treatment with standard therapies, including chemotherapy and monoclonal antibodies targeting vascular endothelial growth factor or epidermal growth factor receptor, have few treatment options. The multikinase inhibitor regorafenib was shown to improve survival in patients with treatment-refractory mCRC in the phase III CORRECT (N = 760) and CONCUR (N = 204) trials. However, safety data on regorafenib for mCRC in a larger number of patients were not available. The CONSIGN trial, carried out prospectively in more than 2,800 patients across 25 countries, confirmed the safety profile of regorafenib from the phase III trials and reinforced the importance of using treatment modifications to manage adverse events.

RESUMEN

Aim: This single institution Phase II study evaluated drug-eluting beads loaded with irinotecan (DEBIRI) plus capecitabine in pretreated patients with colorectal cancer liver metastases. Patients & methods: Forty patients with liver-limited or liver-dominant disease, who have failed at least two previous lines of chemotherapy, underwent either four DEBIRI at 2-week interval or two DEBIRI every 4 weeks for bilobar or single-lobe metastases, respectively. Capecitabine was given at 1000 mg/m2 twice-daily on days 1-14 every 3 weeks. Results: Seven partial responses and 12 stable diseases were observed, achieving a disease control rate of 47.5%. Median progression-free survival and overall survival resulted 4 and 8 months, respectively. Grade 3 adverse events occurred in 6/40 points (15%) of patients. Conclusion: DEBIRI plus capecitabine is a valid treatment option for heavily pretreated patients with colorectal cancer liver metastases.

RESUMEN

OPINION STATEMENT: Unresectable or relapsed malignant pleural mesothelioma (MPM) has dismal prognosis. First-line combination therapy with pemetrexed and a platinum analog allows a modest survival benefit, while no clear therapeutic options exist for the second-line therapy. In this setting, pemetrexed seems to be the most active drug; however, the inclusion in front-line treatment limits its use in further lines. Nevertheless, rechallenge with one or both drugs used in first-line remains a feasible strategy for responder patients. Alternatively, only few cytotoxic drugs have demonstrated a mild activity in refractory MPM. Among other options, targeted therapy has unfortunately produced disappointing results as salvage treatment probably due to the lack of a clear understanding of the tumor biology. In contrast, recent data suggest moderate efficacy and mild toxicity of immunotherapy also for the treatment of MPM. The combination of checkpoint inhibitors with chemotherapy or other immunological agents seems promising and could really "raise the bar" in this setting.

RESUMEN

AIM: To evaluate gefitinib outcomes in EGFR-mutated non-small-cell lung cancer (NSCLC) patients harboring EGFR mutations, according to their sarcopenia status. PATIENTS & METHODS: We retrospectively evaluated 33 patients with advanced NSCLC and EGFR mutations (exon 19 or 21), dividing them into sarcopenic patients, with low skeletal muscle index ≤39 cm2/m2 for women and ≤55 cm2/m2 for men, and nonsarcopenic patients. RESULTS: Sarcopenia does not affect response to gefitinib treatment in EGFR mutated NSCLC patients, even if it is a bad prognostic indicator for overall survival (p = 0.035). CONCLUSION: Early recognition of sarcopenia is beneficial for prevention of cancer cachexia and detection of patients at potential risk of serious adverse events. Gefitinib dosage should be reduced and modulated in sarcopenic patients.

RESUMEN

The optimal duration and intensity of first-line therapy in metastatic colorectal cancer patients once they have achieved an objective response is controversial. In a molecularly selected RAS and BRAF wild-type (wt) population, this concern is amplified. Once disease control has been achieved with a combination therapy including an anti-EGFR antibody, further exposure both to cytotoxic drugs and targeted therapy might result only in increased toxicity. In unresectable metastatic RAS and BRAF wt colorectal cancer patients, a deintensified therapy could represent a valuable option that might preserve quality of life. We designed a study to compare FOLFIRI/cetuximab to FOLFIRI/cetuximab for eight cycles followed by cetuximab alone in first-line treatment of RAS and BRAF (wt) metastatic colorectal cancer patients.

RESUMEN

Our contribution assesses the role of information barriers for patterns of participation in Higher Education (HE) and the related social inequalities. For this purpose, we developed a large-scale clustered randomised experiment involving over 9,000 high school seniors from 62 Italian schools. We designed a counseling intervention to correct student misperceptions of the profitability of HE, that is, the costs, economic returns and chances of success of investments in different tertiary programs. We employed a longitudinal survey to test whether treated students' educational trajectories evolved differently relative to a control group. We find that, overall, treated students enrolled less often in less remunerative fields of study in favour of postsecondary vocational programmes. Most importantly, this effect varied substantially by parental social class and level of education. The shift towards vocational programmes was mainly due to the offspring of low-educated parents; in contrast, children of tertiary graduates increased their participation in more rewarding university fields. Similarly, the redistribution from weak fields to vocational programmes mainly involved the children of the petty bourgeoisie and the working class, while upper class students invested in more rewarding university fields. We argue that the status-maintenance model proposed by Breen and Goldthorpe can explain these socially differentiated treatment effects. Overall, our results challenge the claim that student misperceptions contribute to horizontal inequalities in access to HE.

RESUMEN

BACKGROUND: The literature on hospital admissions costs shows that classification of hospitalization systems such as the DRG system used in Italy, do not reflect the real cost of the production factors used, including those of nursing care in relation to the complexity of the hospital effort. OBJECTIVE: This concept paper outlines the study protocol and the methodology used to measure nursing care in economic terms. The objective of the study is developed on the assumption of creating economic indicators from a quantitative analysis of nursing activities provided to specific patients, in order to determine not only who costs but also the reasons for the cost, and demonstrate the variability of nursing not only for DRG, but also each individual patient. METHODS: A retrospective study and a longitudinal prospective study will be performed. In the first phase of the study, using a bottom-up Microcosting methodology the type, volume, time and costs of nursing activities for DRG will be determined and the incidence of nursing costs on reimbursement will be highlighted.In the second phase, the above analysis will be supplemented by the recognition of the complexity of individual cases measured through the Corridor Triage(Tri-CO), in order to figure out the incidence of costs of nursing activities on the reimbursement in relation to the level of care complexity. Main sources of data: hospital discharge card (SDO); Professional Assessment Instrument (PAI); datasets for collecting the time of delivery of nursing activities on PAI. Power calculation: For retrospective study, the survey will be conducted on a sample of 150 patients hospitalized in the first quarter of 2016. For the longitudinal prospective study, 150 patients will be included in the first quarter of 2017 after the structured introduction of Tri-CO as a valuation tool of care complexity. The sample examined is approximately 30% of the total number of admissions per year. RESULTS: The study started in February 2016 and the results are expected for May 2017. Through this study it is expected to verify whether by implementing a unbundling approach, ie the "unpacking" of the production factors (nursing activity costs) used for the explication of hospitalization, and by adopting a methodology based on standard analytical costs, a more detailed knowledge of the overall DRG rate data available today will be obtained, which is currently lacking of explicit notation of all the amounts that make up it.

RESUMEN

BACKGROUND: Phosphatidylinositol 3-kinase (PI3K) pathway activation in squamous cell carcinoma of the head and neck contributes to treatment resistance and disease progression. Buparlisib, a pan-PI3K inhibitor, has shown preclinical antitumour activity and objective responses in patients with epithelial malignancies. We assessed whether the addition of buparlisib to paclitaxel improves clinical outcomes compared with paclitaxel and placebo in patients with recurrent or metastatic squamous cell carcinoma of the head and neck. METHODS: In this multicentre, randomised, double-blind, placebo-controlled phase 2 study (BERIL-1), we recruited patients aged 18 years and older with histologically or cytologically confirmed recurrent and metastatic squamous cell carcinoma of the head and neck after disease progression on or after one previous platinum-based chemotherapy regimen in the metastatic setting. Eligible patients were enrolled from 58 centres across 18 countries and randomly assigned (1:1) to receive second-line oral buparlisib (100 mg once daily) or placebo, plus intravenous paclitaxel (80 mg/m2 on days 1, 8, 15, and 22) in 28 day treatment cycles. Randomisation was done via a central patient screening and randomisation system with an interactive (voice and web) response system and stratification by number of previous lines of therapy in the recurrent and metastatic setting and study site. Patients and investigators (including local radiologists) were masked to treatment assignment from randomisation until the final overall survival analysis. The primary endpoint was progression-free survival by local investigator assessment per Response Evaluation Criteria In Solid Tumors (version 1.1) in all randomly assigned patients. Efficacy analyses were done on the intention-to-treat population, whereas safety was analysed in all patients who received at least one dose of study drug and had at least one post-baseline safety assessment according to the treatment they received. This trial is registered with ClinicalTrials.gov, number NCT01852292, and is ongoing but no longer enrolling patients. FINDINGS: Between Nov 5, 2013, and May 5, 2015, 158 patients were enrolled and randomly assigned to receive either buparlisib plus paclitaxel (n=79) or placebo plus paclitaxel (n=79). Median progression-free survival was 4·6 months (95% CI 3·5-5·3) in the buparlisib group and 3·5 months (2·2-3·7) in the placebo group (hazard ratio 0·65 [95% CI 0·45-0·95], nominal one-sided p=0·011). Grade 3-4 adverse events were reported in 62 (82%) of 76 patients in the buparlisib group and 56 (72%) of 78 patients in the placebo group. The most common grade 3-4 adverse events (occurring in ≥10% of patients in the buparlisib group vs the placebo group) were hyperglycaemia (17 [22%] of 76 vs two [3%] of 78), anaemia (14 [18%] vs nine [12%]), neutropenia (13 [17%] vs four [5%]), and fatigue (six [8%] vs eight [10%]). Serious adverse events (regardless of relation to study treatment) were reported for 43 (57%) of 76 patients in the buparlisib group and 37 (47%) of 78 in the placebo group. On-treatment deaths occurred in 15 (20%) of 76 patients in the buparlisib group and 17 (22%) of 78 patients in the placebo group; most were caused by disease progression and none were judged to be related to study treatment. INTERPRETATION: On the basis of the improved clinical efficacy with a manageable safety profile, the results of this randomised phase 2 study suggest that buparlisib in combination with paclitaxel could be an effective second-line treatment for patients with platinum-pretreated recurrent or metastatic squamous cell carcinoma of the head and neck. Further phase 3 studies are warranted to confirm this phase 2 finding. FUNDING: Novartis Pharmaceuticals Corporation.

RESUMEN

BACKGROUND: This multicentre phase II trial (DOVIGIST) evaluated the antitumour activity of dovitinib as second-line treatment of patients with gastrointestinal stromal tumour (GIST) refractory to imatinib or who do not tolerate imatinib. METHODS: Patients received oral dovitinib 500 mg day-1, 5 days on/2 days off, until GIST progression or unacceptable toxicity, with an objective to evaluate efficacy, assessed as the disease control rate (DCR) at 12 weeks. Tumour assessment and response to dovitinib therapy were evaluated by Response Evaluation Criteria In Solid Tumours (RECIST v1.1) and the Choi criteria. Secondary objectives included assessment of progression-free survival (PFS), safety and tolerability, and DCR at the end of treatment. RESULTS: Thirty-eight of the 39 patients enrolled had histologically confirmed GIST. The DCR at 12 weeks was 52.6% (90% confidence interval (CI), 38.2-66.7%) meeting the preset efficacy criterion for the primary end point. The objective response rate (complete response+partial response) was 2.6% (1 of 38; 90% CI, 0.1-11.9%), and 5.3% (n=2; 90% CI, 0.9-15.7%) at the end of the study. The median PFS was 4.6 months (90% CI, 2.8-7.4 months). Dose interruption was required in 26 patients (66.7%), of which 18 (69.2%) were due to adverse events. The most frequently observed grade 3 adverse events included hypertension (n=7), fatigue (n=5), vomiting (n=4), hypertriglyceridaemia (n=4), and γ-glutamyltransferase increase (n=4). CONCLUSIONS: Dovitinib is an active treatment for patients with GIST who are intolerant to imatinib or whose GIST progresses on imatinib.

RESUMEN

BACKGROUND: The BALLET study was an open-label, multicenter, expanded access study designed to allow treatment with everolimus plus exemestane in postmenopausal women with hormone receptor-positive metastatic breast cancer progressed following prior endocrine therapy. A post hoc analysis to evaluate if previous chemotherapy in the metastatic setting affects the safety profile of the combination regimen of everolimus and exemestane was conducted on the Italian subset, as it represented the major part of the patients enrolled (54%). PATIENTS AND METHODS: One thousand one hundred and fifty-one Italian patients were included in the present post hoc analysis, which focused on two sets of patients: patients who never received chemotherapy in the metastatic setting (36.1%) and patients who received at least one chemotherapy treatment in the metastatic setting (63.9%). RESULTS: One thousand one hundred and sixteen patients (97.0%) prematurely discontinued the study drug, and the main reasons reported were disease progression (39.1%), local reimbursement of everolimus (31.1%), and adverse events (AEs) (16.1%). The median duration of study treatment exposure was 139.5 days for exemestane and 135.0 days for everolimus. At least one AE was experienced by 92.5% of patients. The incidence of everolimus-related AEs was higher (83.9%) when compared with those that occurred with exemestane (29.1%), and the most commonly reported everolimus-related AE was stomatitis (51.3%). However, no significant difference in terms of safety related to the combination occurred between patients without and with chemotherapy in the metastatic setting. CONCLUSION: Real-life data of the Italian patients BALLET-related cohort were an adequate setting to state that previous chemotherapy did not affect the safety profile of the combination regimen of everolimus and exemestane. IMPLICATIONS FOR PRACTICE: With the advent of new targeted agents for advanced or metastatic breast cancer, multiple lines of therapy may be possible, and components of the combined regimens can overlap from one line to another. Thus, it is important to assess even the potential of cumulative and additive toxic effects among the drugs. Previous chemotherapy did not affect the safety profile of the combination regimen of everolimus and exemestane. The continuous monitoring of the safety signals of this drug combination from general clinical practice is important, in particular for stomatitis.

RESUMEN

PURPOSE: To compare transfemoral approach (TFA) and transradial approach (TRA) in patients undergoing hepatic chemoembolization in terms of safety, feasibility, and procedural variables, including fluoroscopy time, radiation dose (reference air kerma [RAK]), and patient preference. MATERIALS AND METHODS: A single-center prospective intrapatient comparative study was conducted with 42 consecutive patients with hepatic malignancies who received 2 consecutive treatment sessions of unilobar hepatic chemoembolization within a 4-week interval over a 6-month period with both TRA and TFA. All procedures were performed by 1 interventional radiologist who assessed the eligibility of patients for inclusion in the study. The primary endpoint was intraprocedural conversion rate. Secondary endpoints were access site complications, angiographic and procedural variables, and evaluation of patient discomfort and preferences. RESULTS: A 100% technical success rate and a crossover rate of 0% were recorded. There were no major vascular complications and similar rates of minor complications (4.8% for TRA, 7.1% for TFA; P = .095), which were self-limited and without any clinical sequelae. TRA treatments required a significantly longer preparation time for the procedure (P = .008) with no significant differences for other procedural variables. Greater discomfort at the access route and patient inability to perform basic activities after the procedure were recorded for TFA (P < .001). TRA was preferred by 35 patients (35/42) for potential future transarterial procedures. CONCLUSIONS: TRA is safe and feasible for transarterial hepatic chemoembolization, with high technical success, low overall complications, and improved patient comfort.

RESUMEN

This article assesses how processes of social closure enhance intergenerational immobility in the regulated professions and thus promote persistence at the top of the occupational hierarchy. We compare four European countries (GB, Germany, Denmark and Sweden) that differ considerably in their degree of professional regulation and in their broader institutional arrangements. We run log-linear and logistic regression models on a cumulative dataset based on three large-scale surveys with detailed and highly comparable information at the level of unit occupations. Our analyses indicate that children of licensed professionals are far more likely to inherit the occupation of their parents and that this stronger micro-class immobility translates into higher chances of persistence in the upper class. These results support social closure theory and confirm the relevance of a micro-class approach for the explanation of social fluidity and of its cross-national variations. Moreover, we find that, when children of professionals do not reproduce the micro-class of their parents, they still display disproportionate chances of persistence in professional employment. Hence, on the one hand, processes of social closure erect barriers between professions and fuel micro-class immobility at the top. On the other hand, the cultural proximity of different professional groups drives intense intergenerational exchanges between them. Our analyses indicate that these micro- and meso-class rigidities work as complementary routes to immobility at the top.

RESUMEN

Endocrine treatment is the first-line therapy in hormone-sensitive metastatic breast cancer while chemotherapy is the first option in tumors refractory to endocrine therapy and in hormone-negative disease. Optimal duration, efficacy and safety of a maintenance endocrine therapy or chemotherapy after an induction treatment are still a matter of debate. We performed a literature review to identify studies regarding maintenance hormonal and chemotherapy treatments in metastatic breast cancer. We analyzed data relating to efficacy (improvement of progression-free survival and overall survival) and safety (symptoms relief and quality of life [QoL]). Maintenance endocrine therapy could prolong progression-free survival with a better control of symptoms and improving QoL. Maintenance chemotherapy prolong the response to a previous treatment, worsening the QoL, except for metronomic capecitabine.

RESUMEN

OPINION STATEMENT: New treatments-as immunotherapies and new antiangiogenic agents-are now available in second-line setting for patients affected by EGFR wild-type and ALK-negative non-small-cell lung cancer (NSCLC). Nintedanib, ramucirumab, nivolumab and pembrolizumab have to be included in the therapeutic sequences for patients affected by NSCLC, but no clear selection criteria are to date offered, except for patients with PD-L1 expression ≥50 %. Performance status, smoking habits and comorbidities should be considered as clinical criteria in order to select the appropriate treatment, but also tumour characteristics as histotype, platinum resistance and rapid progression after a first-line therapy should be taken into account. The aim of the present paper is to identify subgroups of patients eligible for different therapy sequences.
