A case report of a lung cancer patient with two uncommon EGFR mutations and a review of the literature: two sides of the same coin.

Lung cancer is the malignancy with the highest morbidity and mortality worldwide. Approximately 60% of non-small cell lung cancer (NSCLC) presents driver alterations most of which are targetable. Nowadays, limited clinical data are available regarding the efficacy of epithelial growth factor receptor (EGFR) tyrosine kinase inhibitors in patients with NSCLC harboring uncommon EGFR mutations, considering their heterogeneity. Herein, we report a rare case of EGFR-mutated lung adenocarcinoma which has developed into squamous cell carcinoma with uncommon EGFR (Ex18) compound mutations and phosphatidylinositol 3-kinase mutation receiving afatinib at the forefront.

Oral anticancer therapy project: Clinical utility of a specific home care nursing programme on behalf of Italian Association of Medical Oncology (AIOM).

AIMS AND OBJECTIVES: To assess the effectiveness of a specific home care nursing programme in addition to standard care in patients (pts) receiving oral anticancer treatments. BACKGROUND: Oral anticancer therapy present challenges for pts since treatment is a home-based therapy. This study evaluates the potentiality of a home care nursing programme in decreasing hospital accesses for not severe toxicity. METHODS: This is an open-label, multicentre, randomised trial including pts who were receiving an anticancer oral drug. The study complies with the CONSORT checklist published in 2010. Concomitant use of radiation therapy, intravenous or metronomic therapies, or the intake of previous oral drugs was not allowed. Pts were randomly assigned to home care nursing programme (A) or standard care (B). In arm A, dedicated nurses provided information to pts, a daily record on which pts would take note of drugs and dosages and a telephone monitoring during the first two cycles of therapy. The primary outcome was the reduction in improper hospital accesses for grade 1-2 toxicity according to CTCAE v4.0. RESULTS: Out of 432 randomised pts, 378 were analysed (184 pts in arm A and 194 in arm B). Hospital accesses were observed in 41 pts in arm A and in 42 pts in arm B (22.3% vs. 21.6%, respectively). No difference was detected in proportion of improper accesses between arm A and arm B (29.3% vs. 23.8%, respectively). CONCLUSIONS: Our experience failed to support the role of a specific home care nursing programme for pts taking oral chemotherapy. An improved attention to specific educational practice and information offered to pts can explain these results. RELEVANCE TO CLINICAL PRACTICE: Our results underline the role of nurse educational practice and information offered to patients. A careful nurse information of patients about drugs is essential to reduce toxicities avoiding the opportunity of a specific home monitoring.

Cytidine deaminase enzymatic activity is a prognostic biomarker in gemcitabine/platinum-treated advanced non-small-cell lung cancer: a prospective validation study.

BACKGROUND: Cytidine deaminase (CDA) plays a crucial role in the degradation of gemcitabine. In our previous retrospective study, CDA enzymatic activity was the strongest prognostic biomarker of the activity and efficacy of platinum/gemcitabine combinations. The aim of this prospective study was to validate the prognostic role of CDA activity in the first-line treatment of advanced non-small-cell lung cancer. METHODS: A total of 124 untreated patients received standard doses of platinum/gemcitabine. CDA activity was baseline measured in plasma samples by spectrophotometric assay. RESULTS: Using the median CDA level as cut-off, in the patients with high versus low CDA activity the response rate was 25.0% (95% CI, 14.7-37.8) and 54.1% (95% CI, 40.8-66.9), P = 0.0013; the 6-month progression rate was 34.5% (95% CI, 22.6-46.6) and 54.1% (95% CI, 40.9-65.6), HR = 2.01 (95% CI, 1.32-3.06), P < 0.001; the 1-year survival rate was 23.3% (95% CI, 13.6-34.6) and 57.3% (95% CI, 43.9-68.6), HR = 2.20 (95% CI, 1.46-3.34), P = 0.0002, respectively. CDA activity resulted to be an independent prognostic factor for progression and survival at multivariate analysis. CONCLUSIONS: This study validated prospectively the prognostic role of the CDA activity and should prompt larger and adequately designed randomised prospective studies to establish the predictive impact of this test in improving the outcome of selected patients.

Activity and safety of nivolumab, an anti-PD-1 immune checkpoint inhibitor, for patients with advanced, refractory squamous non-small-cell lung cancer (CheckMate 063): a phase 2, single-arm trial.

BACKGROUND: Patients with squamous non-small-cell lung cancer that is refractory to multiple treatments have poor outcomes. We assessed the activity of nivolumab, a fully human IgG4 PD-1 immune checkpoint inhibitor antibody, for patients with advanced, refractory, squamous non-small-cell lung cancer. METHODS: We did this phase 2, single-arm trial at 27 sites (academic, hospital, and private cancer centres) in France, Germany, Italy, and USA. Patients who had received two or more previous treatments received intravenous nivolumab (3 mg/kg) every 2 weeks until progression or unacceptable toxic effects. The primary endpoint was the proportion of patients with a confirmed objective response as assessed by an independent radiology review committee. We included all treated patients in the analyses. This study is registered with ClinicalTrials.gov, number NCT01721759. FINDINGS: Between Nov 16, 2012, and July 22, 2013, we enrolled and treated 117 patients. 17 (14·5%, 95% CI 8·7-22·2) of 117 patients had an objective response as assessed by an independent radiology review committee. Median time to response was 3·3 months (IQR 2·2-4·8), and median duration of response was not reached (95% CI 8·31-not applicable); 13 (77%) of 17 of responses were ongoing at the time of analysis. 30 (26%) of 117 patients had stable disease (median duration 6·0 months, 95% CI 4·7-10·9). 20 (17%) of 117 patients reported grade 3-4 treatment-related adverse events, including: fatigue (five [4%] of 117 patients), pneumonitis (four [3%]), and diarrhoea (three [3%]). There were two treatment-associated deaths caused by pneumonia and ischaemic stroke that occurred in patients with multiple comorbidities in the setting of progressive disease. INTERPRETATION: Nivolumab has clinically meaningful activity and a manageable safety profile in previously treated patients with advanced, refractory, squamous non-small cell lung cancer. These data support the assessment of nivolumab in randomised, controlled, phase 3 studies of first-line and second-line treatment. FUNDING: Bristol-Myers Squibb.

Efficacy and Safety of Chemotherapy after Immunotherapy in Patients with Advanced Non-Small-Cell Lung Cancer.

Background: There are currently few data about the safety and effectiveness of chemotherapy for patients with metastatic non-small-cell lung cancer (NSCLC) who have progressed from prior immunotherapy. Methods: Data from patients with consecutive stage IIIB-IV, ECOG performance status (PS) 0-2, non-small-cell lung cancer (NSCLC) treated with combination or single-agent chemotherapy following progression on an earlier immunotherapy regimen were retrospectively gathered. Recorded were baseline attributes, outcome metrics, and toxicities. The neutrophil/lymphocyte (N/L) ratio's predictive usefulness was examined through an exploratory analysis. Results: The analysis comprised one hundred subjects. The adeno/squamous carcinoma ratio was 77%/23%, the M/F ratio was 66%/34%, the ECOG PS was 0/1/≥2 47%/51%/2%, and the median PD-L1 expression was 50% (range 0-100). The median age was 67 (range 39-81) years. Prior immunotherapy included a single-agent treatment in 83% of cases, with pembrolizumab use being prevalent, and a median N/L ratio of four prior to chemotherapy. The overall median time-to-progression on previous immunotherapy was 6 months. After immunotherapy, just 33% of subjects underwent chemotherapy. A median of 4 (range 1-16) cycles of chemotherapy were administered; platinum doublets (primarily carboplatin) were delivered in only 31% of cases, vinorelbine accounted for 25%, taxanes for 25%, and gemcitabine for 8%. The median clinical benefit was 55%, while the overall response rate was 21%. The median overall survival was 5 months (range 1-22) and the median time to progression was 4 months (range 1-17). Subgroups with low and high N/L ratios were compared, but there was no discernible difference in survival. Conclusions: After immunotherapy, a small percentage of patients with advanced NSCLC had chemotherapy. Following immunotherapy advancement, chemotherapy demonstrated a moderate level of therapeutic effectiveness; no adverse concerns were noted. The effectiveness of chemotherapy following immunotherapy was not predicted by the baseline N/L ratio.

Early-Stage Non-Small Cell Lung Cancer: Prevalence of Actionable Alterations in a Monocentric Consecutive Cohort.

Early-stage (ES) non-small cell lung cancer (NSCLC) is diagnosed in about 30% of cases. The preferred treatment is surgery, but a significant proportion of patients experience recurrence. Neoadjuvant and adjuvant chemotherapy has a limited clinical benefit. EGFR tyrosine kinase inhibitors and immunotherapy have recently opened new therapeutic scenarios. However, only a few data are available about the ES-NSCLC molecular landscape and the impact of oncogene addiction on therapy definition. Here, we determined the prevalence of the main lung cancer driver alterations in a monocentric consecutive cohort. Molecular analysis was performed on 1122 cases, including 368 ES and 754 advanced NSCLC. The prevalence of actionable alterations was similar between early and advanced stages. ES-NSCLC was significantly enriched for MET exon-14 skipping alterations and presented a lower prevalence of BRAF p.(V600E) mutation. PD-L1 expression levels, evaluated according to actionable alterations, were higher in advanced than early tumors harboring EGFR, KRAS, MET alterations and gene fusions. Taken together, these results confirm the value of biomarker testing in ES-NSCLC. Although approved targeted therapies for ES-NSCLC are still limited, the identification of actionable alterations could improve patients' selection for immunotherapy, favoring the enrollment in clinical trials and allowing a faster treatment start at disease recurrence.

Clinical utility of Next Generation Sequencing of plasma cell-free DNA for the molecular profiling of patients with NSCLC at diagnosis and disease progression.

BACKGROUND: The present study evaluates the utility of NGS analysis of circulating free DNA (cfDNA), which incorporates small amounts of tumor DNA (ctDNA), at diagnosis or at disease progression (PD) in NSCLC patients. METHODS: Comprehensive genomic profiling on cfDNA by NGS were performed in NSCLC patients at diagnosis (if tissue was unavailable/insufficient) or at PD to investigate potential druggable molecular aberrations. Blood samples were collected as routinary diagnostic procedures, DNA was extracted, and the NextSeq 550 Illumina platform was used to run the Roche Avenio ctDNA Expanded Kit for molecular analyses. Gene variants were classified accordingly to the ESCAT score. RESULTS: A total of 106 patients were included in this study; 44 % of cases were requested because of tissue unavailability at the diagnosis and 56 % were requested at the PD. At least one driver alteration was observed in 62 % of cases at diagnosis. Driver druggable variants classified as ESCAT level I were detected in 34 % of patients, including ALK-EML4, ROS1-CD74, EGFR, BRAF, KRAS p.G12C, PI3KCA. In the PD group, most patients were EGFR-positive, progressing to a first line-therapy. Sixty-three percent of patients had at least one driver alteration detected in blood and 17 % of patients had a known biological mechanism of resistance allowing further therapeutic decisions. CONCLUSIONS: The present study confirms the potential of liquid biopsy to detect tumour molecular heterogeneity in NSCLC patients at the diagnosis and at PD, demonstrating that a significant number of druggable mutations and mechanisms of resistance can be detected by NGS analysis on ctDNA.

Real-world outcomes of Italian patients with advanced non-squamous lung cancer treated with first-line pembrolizumab plus platinum-pemetrexed.

PURPOSE: The aim of this multi-center, retrospective/prospective cohort observational study was to evaluate outcomes in routine clinical practice of first-line chemo-immunotherapy with cis/carboplatin, pemetrexed and pembrolizumab in patients with advanced non-squamous non-small cell lung cancer (NSCLC) in 33 Italian centers. METHODS: The outcome measure was to evaluate overall survival (OS) in a real-world patient population. Secondary endpoints were: progression-free survival (PFS), objective response rate (ORR), duration of response (DoR) and incidence of treatment-related adverse events (AEs). RESULTS: 1068 patients were enrolled at the time of data cut-off (January 31st, 2023), and 812 (76.0%) belonged to the retrospective cohort. Median age was 66 years (27-85), ECOG PS was ≥ 2 in 91 (8.6%) patients; 254 (23.8%) patients had brain metastases at baseline; 38 (3.6%) patients had tumor with PD-L1 expression ≥ 50%. After a median follow-up of 17.0 months (95% CI, 16.1-17.9), median OS was 16.1 months (95% CI, 14.4-18.8) and PFS was 9.9 months (95% CI, 8.8-11.2). Median DoR (n = 493) was 14.7 months (95% CI, 13.6-17.1). ORR was 43.4% (95% CI, 40.4-46.4). Any-grade AEs occurred in 636 (59.6%) patients and grade ≥ 3 in 253 (23.7%) patients. Most common grade ≥ 3 AEs were neutropenia (6.3%) and anemia (6.3%). CONCLUSIONS: First-line chemo-immunotherapy was effective and tolerable in this large, real-world Italian study of patients with advanced non-squamous NSCLC. Our results were in line with the KEYNOTE-189 registration study, also considering the low number of PD-L1 ≥ 50% patients included in our study.

Different pathological response and histological features following neoadjuvant chemotherapy or chemo-immunotherapy in resected non-small cell lung cancer.

Introduction: Non-small cell lung cancer (NSCLC) is the leading cause of cancer incidence and mortality worldwide. Neoadjuvant chemo-immunotherapy has led to clinical benefits in resectable NSCLC in comparison to chemo-therapy alone. Major pathological response (MPR) and pathological complete response (pCR) have been used as surrogates of neoadjuvant therapy response and clinical outcomes. However, the factors affecting the pathological response are still controversial. Therefore, in this study we retrospectively examined MPR and pCR in two different cohorts of NSCLC patients, 14 treated by chemotherapy and 12 by chemo-immunotherapy in the neoadjuvant setting. Methods: In resected tumor specimens, different histological characteristics were evaluated: necrosis, fibrosis, inflammation, presence of organizing pneumonia, granuloma, cholesterol cleft, and reactive epithelial alterations. In addition, we evaluated how MPR impacts on event-free survival (EFS) and overall survival (OS). In a small group of patients treated by chemo-immunotherapy, a gene expression analysis of the Hippo pathway was performed both in preoperative biopsies and matched post-surgical specimens. Results: We observed a better pathological response in the chemo-immunotherapy treated cohort: 6/12 patients (50.0%) achieved a MPR ≤10% and 1/12 (8.3%) achieved pCR both on primary tumor and on lymph nodes. On the contrary, no patient treated with chemotherapy alone achieved pCR or MPR ≤10%. A higher amount of stroma in the neoplastic bed was observed in patients treated with immuno-chemotherapy. Moreover, patients achieving better MPR (including pCR) had significantly improved overall survival (OS) and event-free survival (EFS). After neoadjuvant chemo-immunotherapy, residual tumors showed a remarkable upregulation of genes consistent with the activation of YAP/TAZ. Also, alternative checkpoint, such as CTLA-4, were enhanced. Discussion: Our findings showed that neoadjuvant chemo-immunotherapy treatment improves MPR and pCR thus resulting in better EFS and OS. Moreover, a combined treatment could induce different morphological and molecular changes in comparison to chemotherapy alone, thus giving new insights in the assessment of pathological response.

Concomitant Drugs Prognostic Score in Patients With Metastatic Renal Cell Carcinoma Receiving Ipilimumab and Nivolumab in the Compassionate Use Program in Italy: Brief Communication.

A concomitant drug-based score was developed by our group and externally validated for prognostic and predictive purposes in patients with advanced cancer treated with immune checkpoint inhibitors (ICIs). The model considers the use of three classes of drugs within a month before initiating ICI, assigning score 1 for each between proton pump inhibitor and antibiotic administration until a month before immunotherapy initiation and score 2 in case of corticosteroid intake. In the present analysis, the drug score was validated in a prospective population of 305 patients with metastatic renal cell carcinoma treated with ipilimumab plus nivolumab in the first-line setting. The value of the model in predicting overall survival and progression-free survival was statistically significant and clinically meaningful, with an overall survival rate at 12 months of 73% vs. 44% (P<0.0001), and median progression-free survival of 11.6 (95% CI: 9.1-14.1) months versus 4.8 (95% CI: 2.7-7.0) months (P=0.002), respectively, for patients belonging to the favorable group (score 0-1) versus the unfavorable (score 2-4). Further development will be represented by the gut microbiome analysis according to the drug-based model classification and to the outcome of patients to ICI therapy to demonstrate the link between drug exposure and immune sensitivity.

Impact of influenza vaccination on survival of patients with advanced cancer receiving immune checkpoint inhibitors (INVIDIa-2): final results of the multicentre, prospective, observational study.

Background: The prospective multicentre observational INVIDIa-2 study investigated the clinical effectiveness of influenza vaccination in patients with advanced cancer receiving immune checkpoint inhibitors (ICI). In this secondary analysis of the original trial, we aimed to assess the outcomes of patients to immunotherapy based on vaccine administration. Methods: The original study enrolled patients with advanced solid tumours receiving ICI at 82 Italian Oncology Units from Oct 1, 2019, to Jan 31, 2020. The trial's primary endpoint was the time-adjusted incidence of influenza-like illness (ILI) until April 30, 2020, the results of which were reported previously. Secondary endpoints (data cut-off Jan 31, 2022) included the outcomes of patients to immunotherapy based on vaccine administration, for which the final results are reported herein. A propensity score matching by age, sex, performance status, primary tumour site, comorbidities, and smoking habits was planned for the present analysis. Only patients with available data for these variables were included. The outcomes of interest were overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and disease-control rate (DCR). Findings: The original study population consisted of 1188 evaluable patients. After a propensity score matching, 1004 patients were considered (502 vaccinated and 502 unvaccinated), and 986 of them were evaluable for overall survival (OS). At the median follow-up of 20 months, the influenza vaccination demonstrated a favourable impact on the outcome receiving ICI in terms of median OS [27.0 months (CI 19.5-34.6) in vaccinated vs. 20.9 months (16.6-25.2) in unvaccinated, p = 0.003], median progression-free survival [12.5 months (CI 10.4-14.6) vs. 9.6 months (CI 7.9-11.4), p = 0.049], and disease-control rate (74.7% vs. 66.5%, p = 0.005). The multivariable analyses confirmed the favourable impact of influenza vaccination in terms of OS (HR 0.75, 95% C.I. 0.62-0.92; p = 0.005) and DCR (OR 1.47, 95% C.I. 1.11-1.96; p = 0.007). Interpretation: The INVIDIa-2 study results suggest a favourable immunological impact of influenza vaccination on the outcome of cancer patients receiving ICI immunotherapy, further encouraging the vaccine recommendation in this population and supporting translational investigations about the possible synergy between antiviral and antitumour immunity.

Adjuvant chemotherapy of pT1a and pT1b breast carcinoma: results from the NEMESI study.

BACKGROUND: The prognosis of pT1a-pT1b breast cancer (BC) used to be considered very good, with a 10-y RFS of 90%. However, some retrospective studies reported a 10-y RFS of 81%-86% and suggested benefit from adjuvant systemic therapy. METHODS: To evaluate the variables that determined the choice of adjuvant chemotherapy and the type of chemotherapy delivered in pT1a-pT1b BC, we analysed the small tumours enrolled in the NEMESI study. RESULTS: Out of 1,894 patients with pathological stage I-II BC enrolled in NEMESI, 402 (21.2%) were pT1a-pT1b. Adjuvant chemotherapy was delivered in 127/402 (31.59%). Younger age, grading G3, high proliferative index, ER-negative and HER2-positive status were significantly associated with the decision to administer adjuvant chemotherapy. An anthracycline without taxane regimen was administered in 59.1% of patients, anthracycline with taxane in 24.4%, a CMF-like regimen in 14.2% and taxane in 2.4%. Adjuvant chemotherapy was administered in 88.4% triple-negative and 73.46% HER2-positive pT1a-pT1b BC. Adjuvant trastuzumab was delivered in 30/49 HER2-positive BC (61.2%). CONCLUSIONS: Adjuvant chemotherapy was delivered in 31.59% T1a-pT1b BC treated at 63 Italian oncological centres from January 2008 to June 2008. The choice to deliver chemotherapy was based on biological prognostic factors. Anthracycline-based chemotherapy was administered in 83.5% patients.

Ribociclib Plus Letrozole in Italian Male Patients with Hormone Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative Advanced Breast Cancer: Case Studies of Phase 3b CompLEEment-1 Trial.

Abstract: Male breast cancer (BC) is rare, globally constituting only 0.5-1% of all patients with BC. In Italy, more than 2000 new male BC cases were registered between 2000 and 2014. The survival rate was lower in males than in females. Delayed diagnosis may be the reason for poorer outcome observed in male BC patients compared with female patients. Due to lack of substantial evidence and low availability of published data on male BC, the current treatment recommendations are based on evidence derived from trials on female patients. In Italy, most of the male BC patients are estrogen and progesterone receptor-positive. Targeted therapy in combination with endocrine therapy provides a clinically meaningful outcome in patients with hormone receptor-positive (HR-positive), human epidermal growth factor receptor 2-negative (HER2-negative) advanced BC. CompLEEment-1 is a single-arm, open-label, multicenter, phase 3b trial investigating the safety and efficacy of a CDK4/6 inhibitor, ribociclib, in combination with letrozole in men and women. Herein, we report the results from a retrospective analysis of five Italian male patients who completed the core phase. In this case series, the combination of ribociclib and letrozole was well tolerated and appeared to be effective in the male cohort with HR-positive, HER2-negative advanced BC in Italy. CompLEEment-1 trial representative of a real-world setting would add value by supporting the existing efficacy and safety profile of ribociclib in combination with letrozole in male patients with HR-positive, HER2-negative advanced BC. ClinicalTrialsgov Registration Number: NCT02941926.

Pembrolizumab for First-Line Treatment of Advanced Non-Small-Cell Lung Cancer: Analysis of Prognostic Factors of Outcomes.

BACKGROUND: In advanced non-small-cell lung cancer, without activating mutations and with PD-L1≥50%, Pembrolizumab monotherapy is the therapeutic standard in Europe. OBJECTIVE: To evaluate retrospectively the safety and efficacy of this drug and to investigate potential prognostic factors in daily clinical practice. METHODS: From September 2017 to September 2019, 205 consecutive patients from 14 Italian Medical Oncology Units were enrolled in the study. Gender, Age (> or <70 years), ECOG-PS (0-1 or 2), histology (squamous or nonsquamous), presence of brain, bone and liver metastases at baseline, PD-L1 score (>90% or <90%), smoking status (never or former or current) were applied to the stratified log-rank. Cox's proportional hazards model was used for multivariate analysis. RESULTS: At a median follow-up of 15.2 months, median progression-free and overall survival (mPFS and mOS) were 9.2 months (95% C.I., 4.8-13.5) and 15.9 months (95% C.I., not yet evaluable), respectively. Patients with Eastern Cooperative Oncology Group performance status (ECOG-PS) 2 had mPFS of 2.8 months (95% C.I., 2.1-3.4) and mOS of 3.9 months (95% C.I., 2.5-5.3). Patients with liver metastases at diagnosis had an mPFS of 3.2 months (95% C.I., 0.6-5.8) and an mOS of 6.0 months (95% C.I., 3.7-8.4). At multivariate analysis for OS gender, ECOG-PS 2, and presence of liver metastases were independent prognostic factors. CONCLUSION: Patients with ECOG-PS 2 derived little benefit from the use of first-line pembrolizumab. In patients with liver metastases, the association of pembrolizumab with platinum-based chemotherapy could be a better option than pembrolizumab alone.

Randomized phase III trial of adjuvant epirubicin followed by cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) versus CMF followed by epirubicin in patients with node-negative or 1-3 node-positive rapidly proliferating breast cancer.

Adjuvant cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) have proven highly effective in rapidly proliferating breast cancer (RPBC). It has also been seen that sequential administration of doxorubicin and CMF is superior to their alternation, especially in indolent tumors. In a phase III study, we evaluated whether adjuvant epirubicin (E) followed by CMF is superior to the inverse sequence in RPBC. Patients with node-negative or 1-3 node-positive RPBC (Thymidine Labeling Index > 3% or histological grade 3 or S-phase > 10% or Ki67 > 20%) were randomized to receive E (100 mg/m(2) i.v. d1, q21 days for 4 cycles) followed by CMF (600, 40, 600 mg/m(2) i.v. d1 and 8, q28 days for 4 cycles) (E â†’ CMF) or CMF followed by E (CMF â†’ E) or CMF for 6 cycles. From November 1997 to December 2004, 1066 patients were enrolled: E â†’ CMF 440, CMF â†’ E 438, and CMF 188. At a median follow-up of 69 months, 5-year OS was 91% (95% CI 88-94) for E â†’ CMF and 93% (95% CI 90-95) for CMF â†’ E, with adjusted hazard ratio of 0.88 (95% CI 0.58-1.35), and DFS was 80% in both arms, with adjusted hazard ratio of 0.99 (95% CI 0.73-1.33, Cox model). Adverse events were similar, apart from a higher rate of neutropenia in the CMF â†’ E arm. No important differences in clinical outcome were observed between the two different sequences, making both a valid option in early breast cancer. Further molecular characterization of the tumors might help to identify subgroups achieving higher benefit from either sequence.

Differences in the availability of new anti-cancer drugs for Italian patients treated in different regions. Results of analysis conducted by the Italian Society Of Medical Oncology (AIOM).

AIMS AND BACKGROUND: Italy is divided into 20 regions. As a consequence of local autonomy, following marketing authorization by the Italian Medicines Agency, each drug for hospital use is not immediately available, because its approval needs to undergo further steps that can be different among regions. The Italian Society of Medical Oncology conducted the present study to describe the impact of the existence of sub-national pharmaceutical formularies on the disparity of access to new anti-cancer drugs among patients treated in different Italian regions. METHODS: The availability of 8 new anti-cancer drugs at a regional level and the coherence of regional authorizations compared with national authorizations approved by the Italian Medicines Agency were analyzed as of April 2009. RESULTS: Fourteen regions and autonomous province of Trento have a regional pharmaceutical formulary. In most cases, the regional pharmaceutical formularies include the eight analyzed drugs, with therapeutic indications coherent with national marketing authorization indications. Five drugs (bevacizumab, trastuzumab, rituximab, erlotinib, sunitinib) were included in all the existing regional pharmaceutical formularies, without restrictions, whereas three drugs (cetuximab, sorafenib, pemetrexed) were found to have restrictions in some regions. CONCLUSIONS: The presence of multiple hierarchical levels of drug evaluation creates a potential element of disparity in the access to pharmacological therapies for Italian citizens.

Immune-related adverse events correlate with clinical outcomes in NSCLC patients treated with nivolumab: The Italian NSCLC expanded access program.

OBJECTIVES: The incidence of any and of severe-grade immune-related adverse events (irAEs) with second-line nivolumab monotherapy is 31-65 % and 2-5 % respectively. While potentially serious and even fatal, in the absence of an appropriate therapy, such events might be indicators of the activation of the immune system and, potentially, of efficacy. MATERIALS AND METHODS: We collected the records of 1959 non-small-cell lung cancer (NSCLC) patients treated with nivolumab in the Italian expanded access program, and we registered the appearance of any and of severe grade irAEs. We retrospectively searched for correlations between toxicity and efficacy parameters by using Cox's regression analysis. RESULTS: Overall, 342 (17.8%) patients developed an irAE of any grade. We observed that patients developing irAE of any grade achieved a significantly higher response rate (RR 27.2% vs 15.2%; p < 0.0001), disease control rate (DCR 60.5% vs 40.2%; p < 0.0001), median progression-free survival (mPFS 6.0 months [95% CI 4.9-7.1] vs 3.0 [95% CI: 2.8-3.2], p < 0.0001) and median overall survival (mOS 16.7 months [95% CI: 13.5-19.9] vs 9.4 [95% CI: 8.4-10.4], p < 0.00001) compared to patients who did not. At multivariate analysis the development of an irAE remained an independent indicator of nivolumab efficacy (HR 1.44 [95% CI: 1.22-1.71] p < 0.0001). CONCLUSIONS: This report, performed in Caucasian NSCLC patients, showed that the appearance of irAEs correlated with outcome.

Epidermal growth factor receptor and K-RAS mutations in 411 lung adenocarcinoma: a population-based prospective study.

Targeting the epidermal growth factor receptor has played a central role in advanced non-small cell lung cancer research, treatment, and patient outcomes over the last several years; however, a number of questions about this approach remain to be addressed. Through the Istituto Toscano Tumori and the Italian Association of Women Against Lung Cancer Project, we collected 411 lung adenocarcinomas from several clinical centers in Tuscany. Mutations were assessed by sequencing exons 18-21 of the epidermal growth factor receptor gene, and by restriction fragment length polymorphism analysis of codons 12 and 13 of the K-RAS gene. Epidermal growth factor receptor mutations (12.6%) were more frequently observed in females (p<0.0001), in non-smokers (p=0.005), and in the presence of bronchioloalveolar features (p=0.0004). K-RAS mutations (17.9%) were more frequent in males (p=0.0007) and were associated with smoking habits (p=0.005). Epidermal growth factor receptor and K-RAS mutations were mutually exclusive (p=0.001). We focused on 21 female patients with advanced/metastatic lung adenocarcinoma who received gefitinib 250 mg/day (expanded access) or erlotinib 150 mg/die as second/third-line therapy; partial response was associated with classic epidermal growth factor receptor mutations (p=0.006) and with a non-smoking history (p=0.02). None of the female patients with partial response and/or stable disease showed K-RAS alterations. Although the data obtained in our study have yet to be analyzed and confirmed with a larger number of patients treated with tyrosine kinase inhibitors, they should provide useful information for targeted therapy, in particular for non-smoking female lung cancer patients.

Treatment of metastatic non-small cell lung cancer: 2018 guidelines of the Italian Association of Medical Oncology (AIOM).

The treatment landscape of metastatic non-small cell lung cancer (NSCLC) has dramatically evolved in recent years, since the recognition of several clinical-biological entities requiring personalized treatment approaches, leading to significant improvements in patients' survival outcomes. In particular, targeted therapies acting against EGFR, ALK, and ROS1, and immunotherapeutic agents modulating the PD-1/PD-L1 axis, represent new milestones in the treatment of advanced disease, supporting a chemotherapy backbone within a multidisciplinary model. The Italian Association of Medical Oncology (AIOM) has developed evidence-based guidelines for the management of lung tumors. Given the epidemiologic relevance, this report is dedicated to the treatment of advanced/metastatic NSCLC. These guidelines serve as a practical tool for oncologists, physicians, and other healthcare professionals to easily embrace the updated key points of NSCLC treatment strategies. Considering the upcoming introduction of potential new standards of care in several disease settings, these guidelines represent a benchmark from which to move forward.

Management of locally advanced non-small cell lung cancer in the modern era: A national Italian survey on diagnosis, treatment and multidisciplinary approach.

Concurrent chemotherapy and radiotherapy (cCRT) is considered the standard treatment of locally advanced non-small cell lung cancer (LA-NSCLC). Unfortunately, management is still heterogeneous across different specialists. A multidisciplinary approach is needed in this setting due to recent, promising results obtained by consolidative immunotherapy. The aim of this survey is to assess current LA-NSCLC management in Italy. From January to April 2018, a 15-question survey focusing on diagnostic/therapeutic LA-NSCLC management was sent to 1,478 e-mail addresses that belonged to pneumologists, thoracic surgeons, and radiation and medical oncologists. 421 answers were analyzed: 176 radiation oncologists, 86 medical oncologists, 92 pneumologists, 64 thoracic surgeons and 3 other specialists. More than a half of the respondents had been practicing for >10 years after completing residency training. Some discrepancies were observed in clinical LA-NSCLC management: the lack of a regularly planned multidisciplinary tumor board, the use of upfront surgery in multistation stage IIIA, and territorial diffusion of cCRT in unresectable LA-NSCLC. Our analysis demonstrated good compliance with international guidelines in the diagnostic workup of LA-NSCLC. We observed a relationship between high clinical experience and good clinical practice. A multidisciplinary approach is mandatory for managing LA-NSCLC.
