Addition of Bevacizumab to Erlotinib as First-Line Treatment of Patients With EGFR-Mutated Advanced Nonsquamous NSCLC: The BEVERLY Multicenter Randomized Phase 3 Trial.

INTRODUCTION: Adding bevacizumab to erlotinib prolonged progression-free survival (PFS) of patients with EGFR-mutated advanced NSCLC in the Japanese JO25567 trial, but limited data were available in non-Asian patients. BEVERLY is an Italian, multicenter, randomized, phase 3 investigating the addition of bevacizumab to erlotinib as first-line treatment of advanced EGFR-mutated NSCLC. METHODS: Eligible patients were randomized 1:1 to erlotinib plus bevacizumab or erlotinib alone. Investigator-assessed PFS and blinded independent centrally reviewed PFS were coprimary end points. With 80% power in detecting a 0.60 hazard ratio and two-sided α error of 0.05, 126 events of 160 patients were needed. The trial was registered as NCT02633189 and EudraCT 2015-002235-17. RESULTS: From April 11, 2016, to February 27, 2019, a total of 160 patients were randomized to erlotinib plus bevacizumab (80) or erlotinib alone (80). At a median follow-up of 36.3 months, median investigator-assessed PFS was 15.4 months (95% confidence interval [CI]: 12.2-18.6) with erlotinib plus bevacizumab and 9.6 months (95% CI: 8.2-10.6) with erlotinib alone (hazard ratio = 0.66, 95% CI: 0.47-0.92). Blinded independent centrally reviewed PFS analysis confirmed this result. A statistically significant interaction with treatment effect was found for smoking habit (p = 0.0323), with PFS prolongation being clinically significant only among current or previous smokers. Hypertension (grade ≥3: 24% versus 5%), skin rash (grade ≥ 3: 31% versus 14%), thromboembolic events (any grade: 11% versus 4%), and proteinuria (any grade: 23% versus 6%) were more frequent with the combination. CONCLUSIONS: The addition of bevacizumab to first-line erlotinib prolonged PFS in Italian patients with EGFR-mutated NSCLC; toxicity was increased with the combination but without unexpected safety issues.

Definition of the Prognostic Role of MGMT Promoter Methylation Value by Pyrosequencing in Newly Diagnosed IDH Wild-Type Glioblastoma Patients Treated with Radiochemotherapy: A Large Multicenter Study.

Background. O6-methylguanine (O6-MeG)-DNA methyltransferase (MGMT) methylation status is a predictive factor for alkylating treatment efficacy in glioblastoma patients, but its prognostic role is still unclear. We performed a large, multicenter study to evaluate the association between MGMT methylation value and survival. Methods. We evaluated glioblastoma patients with an assessment of MGMT methylation status by pyrosequencing from nine Italian centers. The inclusion criteria were histological diagnosis of IDH wild-type glioblastoma, Eastern Cooperative Oncology Group Performance Status (ECOG-PS) ≤2, and radio-chemotherapy treatment with temozolomide. The relationship between OS and MGMT was investigated with a time-dependent Receiver Operating Characteristics (ROC) curve and Cox regression models. Results. In total, 591 newly diagnosed glioblastoma patients were analyzed. The median OS was 16.2 months. The ROC analysis suggested a cut-off of 15% for MGMT methylation. The 2-year Overall Survival (OS) was 18.3% and 51.8% for MGMT methylation <15% and ≥15% (p < 0.0001). In the multivariable analysis, MGMT methylation <15% was associated with impaired survival (p < 0.00001). However, we also found a non-linear association between MGMT methylation and OS (p = 0.002): median OS was 14.8 months for MGMT in 0−4%, 18.9 months for MGMT in 4−40%, and 29.9 months for MGMT in 40−100%. Conclusions. Our findings suggested a non-linear relationship between OS and MGMT promoter methylation, which implies a varying magnitude of prognostic effect across values of MGMT promoter methylation by pyrosequencing in newly diagnosed IDH wild-type glioblastoma patients treated with chemoradiotherapy.

Patient-reported outcomes in a phase II randomised study of regorafenib compared with lomustine in patients with relapsed glioblastoma (the REGOMA trial).

BACKGROUND: The REGOMA trial showed that regorafenib significantly improved overall survival in patients with recurrent glioblastoma compared with lomustine. Patients treated with regorafenib experienced a higher occurrence of grade 3-4 drug-related adverse events than those receiving the standard treatment. Because this safety profile was expected, it was considered of great importance to assess the patient point of view regarding the disease and treatment impact on different aspects of life and patient well-being. We here report the final results of the health-related quality of life (HRQoL) assessment, a secondary end-point of the study. This trial is registered with ClinicalTrials.gov, NCT02926222. METHODS: Patient-reported outcomes were assessed, within a prospective, randomised, multicentre, open-label phase II trial, by the European Organisation for Research and Treatment of Cancer core questionnaire and brain module at baseline and every 8-weekly neuroradiological assessment till disease progression. Mixed-effect linear models were fitted for each of the HRQoL domain to examine the change over progression-free time within and between arms. Furthermore, differences were also classified as clinically meaningful changes. To correct for multiple comparisons and avoid type I errors, the level of significance was set at P = 0.01 (2-sided). RESULTS: Of 119 enrolled patients, 56/59 (95%) patients and 58/60 (97%) patients treated with regorafenib and lomustime completed questionnaires at baseline, respectively. No significant differences were observed in any generic or cancer-specific domain during treatment in both arms, or between the two arms, except for the appetite loss and diarrhoea scales which were significantly worse in patients treated with regorafenib. The rate of patients with a clinically meaningful worsening for appetite loss, diarrhoea and for any other domain was not statistically different between the two arms. CONCLUSIONS: Regorafenib did not negatively affect HRQoL in patients with recurrent glioblastoma. These data combined with the survival benefit shown in the REGOMA trial support the use of regorafenib as a treatment option for these patients.

Depatuxizumab Mafodotin (Depatux-M) Plus Temozolomide in Recurrent Glioblastoma Patients: Real-World Experience from a Multicenter Study of Italian Association of Neuro-Oncology (AINO).

BACKGROUND: Depatuxizumab Mafodotin (Depatux-M; ABT-414) is an antibody-drug conjugate consisting of a specific antibody against activated EGFR and a cytotoxic agent with antimicrotubule activity. The INTELLANCE 2/EORTC 1410 phase 2 trial produced interesting results for the combination regimen of Depatux-M and temozolomide in EGFR-amplified glioblastoma patients at first recurrence. For the first time worldwide, our work investigated the clinical outcome and safety of this combination in a real-life population. MATERIALS AND METHODS: Patients were enrolled from seven AINO (Italian Association of Neuro-Oncology) Institutions. The major inclusion criteria were: histologically confirmed diagnosis of glioblastoma, EGFR-amplified, one or more prior systemic therapies and ECOG PS ≤ 2. According to the original schedule, patients received Depatux-M 1.25 mg/kg every 2 weeks combined with temozolomide. The primary endpoints of the study were overall survival and safety. RESULTS: A total of 36 patients were enrolled. The median age was 57 years, ECOG PS was 0-1 in 28 patients (88%), MGMT methylated status was found in 22 (64%), 15 patients (42%) received the combined treatment as second-line therapy. The median OS was 8.04 months (95% CI, 5.3-10.7), the 12 month-OS was 37%. On univariate and multivariate analyses, the MGMT methylation status was the only factor resulting significantly associated with survival. Grade 3 ocular toxicity occurred in 11% of patients; no grade 4 ocular toxicity was reported. No death was considered to be drug-related. CONCLUSIONS: The study reported the first "real world" experience of Depatux-M plus temozolomide in recurrent glioblastoma patients. Encouraging clinical benefits were demonstrated, even though most patients were treated beyond second-line therapy. Overall, the results are close to those reported in the previous phase 2 trial. Toxicity was moderate and manageable.

Adjuvant chemotherapy after severe myelotoxicity during chemoradiation phase in malignant gliomas. Is it feasibile? Results from AINO study (Italian Association for Neuro-Oncology).

BACKGROUND: Malignant gliomas (MG) are aggressive brain tumours in adults. The standard of care is concurrent radiation plus temozolomide (TMZ) [chemo-radiotherapy (CRT)] followed by TMZ maintenance up to 6 months. TMZ is considered to have a low toxicity profile, but several studies reported occurrence of severe myelosuppression, especially during the concomitant phase. Toxicity may be prolonged, thus treatment should be discontinued. PURPOSE: To evaluate the risk of recurrente myelotoxicity during adjuvant chemotherapy (CT) in patients who recovered from severe myelotoxicity during CRT. METHODS: We retrospectively collected data on patients with MG who developed and recovered from severe myelotoxicity during CRT from eight Italian neuro-oncology centers. RESULTS: We included 87 patients. Histology was Glioblastoma (GBM) in 78 patients (89.7%); 60% of patients were female. After myelotoxicity recovery, 54 (62%) received treatment. The majority of them (82%, n = 44) received adjuvant TMZ and 18% (n = 10) others treatments. Out of 44 patients who received adjuvant TMZ, 34% experienced the re-occurrence of grade 3-4 myelotoxicity which required permanent CT discontinuation in 6 (13%) cases. Patients who received TMZ or other treatments had longer overall (OS) (adjusted HR 0.46, p = 0.008) and progression free survival (PFS) (adjusted HR 0.57, p = 0.034) than those who remained untreated. CONCLUSION: Our study suggests that after severe myelotoxicity the majority of patients received treatment, particularly with TMZ. Only a fraction of patients experienced toxicity recurrence, suggesting that TMZ is well tolerated and had an impact on PFS and OS.

Afatinib in EGFR TKI-naïve patients with locally advanced or metastatic EGFR mutation-positive non-small cell lung cancer: Interim analysis of a Phase 3b study.

OBJECTIVES: Randomized controlled trials have demonstrated that afatinib is a suitable treatment option for patients with epidermal growth factor receptor mutation-positive (EGFRm +) non-small cell lung cancer (NSCLC). However, such studies often exclude patients treated in routine clinical practice. We report interim results from a Phase 3b, open-label, multicenter, single-arm, exploratory trial, in which afatinib was investigated in a real-world setting. MATERIALS AND METHODS: Patients with EGFRm + tyrosine kinase inhibitor (TKI)-naïve NSCLC received afatinib 40 mg orally, once-daily, until disease progression, or voluntary withdrawal. Primary objective was safety. RESULTS: Overall, 479 patients received afatinib: median age 65 years, 8 % of patients had an ECOG performance status ≥ 2, 17 % had brain metastases, and 13 % had tumors containing uncommon mutations only. All but one patient (99.8 %) had an adverse event (AE). Treatment-related AEs (TRAEs; any/grade ≥ 3) occurred in 97 %/44 % of patients; most common were diarrhea (87 %/16 %) and rash (51 %/11 %). AEs leading to afatinib dose-reduction were reported in 258 patients (54 %), and 37 patients (8 %) discontinued treatment due to a TRAE. Objective response rate was 45.5 %, median duration of response was 14.1 months (95 % CI: 12.2-16.4). Overall median time to symptomatic progression and progression-free survival were 14.9 months (95 % CI: 13.8-17.6) and 13.4 months (95 % CI: 11.8-14.5), respectively, in the overall population and 19.3 months (95 % CI: 15.6-21.8) and 15.9 months (95 % CI: 13.9-19.1) in patients with EGFR exon 19 deletions. CONCLUSIONS: Afatinib administration in routine clinical practice was well tolerated with no new safety signals and demonstrated promising efficacy in patients with EGFRm + NSCLC. TRAEs were generally manageable with tolerability-guided dose reductions. Overall, these data independently support findings from randomized controlled trials of afatinib in EGFRm + NSCLC.

A molecular signature associated with prolonged survival in glioblastoma patients treated with regorafenib.

BACKGROUND: Patients with glioblastoma (GBM) have a dramatically poor prognosis. The recent REGOMA trial suggested an overall survival (OS) benefit of regorafenib in recurrent GBM patients. Considering the extreme genetic heterogeneity of GBMs, we aimed to identify molecular biomarkers predictive of differential response to the drug. METHODS: Total RNA was extracted from tumor samples of patients enrolled in the REGOMA trial. Genome-wide transcriptome and micro (mi)RNA profiles were associated with patients' OS and progression-free survival. RESULTS: In the first step, a set of 11 gene transcripts (HIF1A, CTSK, SLC2A1, KLHL12, CDKN1A, CA12, WDR1, CD53, CBR4, NIFK-AS1, RAB30-DT) and 10 miRNAs (miR-93-5p, miR-203a-3p, miR-17-5p, let-7c-3p, miR-101-3p, miR-3607-3p, miR-6516-3p, miR-301a-3p, miR-23b-3p, miR-222-3p) was filtered by comparing survival between regorafenib and lomustine arms. In the second step, a mini-signature of 2 gene transcripts (HIF1A, CDKN1A) and 3 miRNAs (miR-3607-3p, miR-301a-3p, miR-93-5p) identified a subgroup of patients showing prolonged survival after regorafenib administration (median OS range, 10.6-20.8 mo). CONCLUSIONS: The study provides evidence that a signature based on the expression of 5 biomarkers could help identify a subgroup of GBM patients exhibiting a striking survival advantage when treated with regorafenib. Although the presented results must be confirmed in larger replication cohorts, the study highlights potential biomarker options to help guide the clinical decision among regorafenib and other treatments in patients with relapsing GBM.

Platinum-Based Chemotherapy in Older Patients with Non-Small Cell Lung Cancer: What to Expect in the Real World.

BACKGROUND: The role of platinum-based chemotherapy (PBC) for the treatment of older patients with non-small cell lung cancer (NSCLC) is still a matter of debate, despite the advent of immunotherapy. OBJECTIVE: The aim of the study was to identify factors associated with first-line PBC prescription and, secondly, to evaluate the impact of first-line PBC on survival, treatment intensity, risk of hospitalization, and subsequent treatments. PATIENTS AND METHODS: We reviewed a consecutive series of 474 older patients (age ≥ 70 years) diagnosed with stage IIIB-IV NSCLC at the Department of Oncology, University Hospital of Udine, Italy from January 2009 to March 2017. RESULTS: Overall, 198 patients were deemed eligible, and 65.2% received a PBC. At multivariate analysis, older age was the only factor associated with PBC prescription. In the whole cohort, 46 patients (23.2%) were hospitalized for chemotherapy-related toxicity. Both PBC prescription (odds ratio [OR] 2.23, 95% confidence interval [CI] 1.02-4.87, p = 0.04) and tumor burden (OR 2.39, 95% CI 1.07-5.32, p = 0.03) emerged as independent risk factors for hospitalization. Moving to significant predictors of patterns of care, Eastern Cooperative Oncology Group (ECOG) performance status > 0 was associated with greater risk of first-line failure (OR 2.20, 95% CI 1.15-4.20, p = 0.02), while bone metastases (OR 0.29, 95% CI 0.12-0.69, p = 0.005) and a Charlson Comorbidity Index score ≥ 3 (OR 0.40, 95% CI 0.19-0.84, p = 0.016) independently predicted lower probability of receiving second-line therapy. Remarkably, PBC did not significantly impact overall survival (hazard ratio [HR] 0.83, 95% CI 0.61-1.14, p = 0.24) and progression-free survival (HR 0.95, 95% CI 0.70-1.28, p = 0.73) compared to single-agent chemotherapy (SAC). However, according to an exploratory landmark analysis, patients who received four cycles of treatment or maintenance therapy experienced prolonged overall survival, regardless of PBC use. CONCLUSIONS: This study evaluated the real-world use of PBC in older patients with NSCLC, offering an insight into the determinants of its prescription and the pattern of care of these patients. Of note, PBC use was associated with a higher likelihood of hospitalization for chemotherapy-related toxicity, with no benefit on survival compared to SAC.

Phosphorylated Acetyl-CoA Carboxylase Is Associated with Clinical Benefit with Regorafenib in Relapsed Glioblastoma: REGOMA Trial Biomarker Analysis.

PURPOSE: Preclinical studies show that antiangiogenic therapy exacerbates tumor glycolysis and activates liver kinase B1/AMP kinase (AMPK), a pathway involved in the regulation of tumor metabolism. We investigated whether certain metabolism-related in situ biomarkers could predict benefit to regorafenib in the phase II randomized REGOMA trial. PATIENTS AND METHODS: IHC and digital pathology analysis were used to investigate the expression in glioblastoma (GBM) sections of monocarboxylate transporter 1 and 4 (MCT1 and MCT4), associated with OXPHOS and glycolysis, respectively, phosphorylated AMPK (pAMPK), and phosphorylated acetyl-CoA carboxylase (pACC), a canonical target of AMPK activity. The status of each biomarker was associated with clinical endpoints, including overall survival (OS) and progression-free survival (PFS) in patients with relapsed GBM treated either with regorafenib or lomustine. RESULTS: Between November 2015 and February 2017, 119 patients were enrolled (n = 59 regorafenib and n = 60 lomustine) and stratified for surgery at recurrence, and baseline characteristics were balanced. Biomarker analysis was performed in 84 patients (71%), including 42 patients of the regorafenib arm and 42 patients of the lomustine arm. Among all markers analyzed, only pACC showed predictive value in terms of OS. In fact, median OS was 9.3 months [95% confidence interval (CI), 5.6-13.2] for regorafenib and 5.5 months (95% CI, 4.2-6.6) for lomustine for pACC-positive patients, HR, 0.37 (95% CI, 0.20-0.70); log rank P = 0.0013; test for interaction = 0.0453. No statistically significant difference was demonstrated for PFS according to pACC status. CONCLUSIONS: We found that AMPK pathway activation is associated with clinical benefit from treatment with regorafenib in relapsed GBM.

Regorafenib compared with lomustine in patients with relapsed glioblastoma (REGOMA): a multicentre, open-label, randomised, controlled, phase 2 trial.

BACKGROUND: Glioblastoma is a highly vascularised tumour and there are few treatment options after disease recurrence. Regorafenib is an oral multikinase inhibitor of angiogenic, stromal, and oncogenic receptor tyrosine kinases. We aimed to assess the efficacy and safety of regorafenib in the treatment of recurrent glioblastoma. METHODS: REGOMA is a randomised, multicentre, open-label phase 2 trial done in ten centres in Italy. Eligible patients (aged ≥18 years) with histologically confirmed glioblastoma, Eastern Cooperative Oncology Group performance status 0 or 1, and documented disease progression after surgery followed by radiotherapy and temozolomide chemoradiotherapy were randomly assigned (1:1) by a web-based system, stratified by centre and surgery at recurrence (yes vs no), to receive regorafenib 160 mg once daily for the first 3 weeks of each 4-week cycle or lomustine 110 mg/m2 once every 6 weeks until disease progression, death, unacceptable toxicity, or consent withdrawal. The primary endpoint was overall survival in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT02926222, and is currently in follow-up. FINDINGS: Between Nov 27, 2015, and Feb 23, 2017, 124 patients were screened and 119 eligible patients were randomly assigned to receive regorafenib (n=59) or lomustine (n=60). Median follow-up was 15·4 months (IQR 13·8-18·1). At the analysis cutoff date, 99 (83%) of 119 patients had died: 42 (71%) of 59 in the regorafenib group and 57 (95%) of 60 in the lomustine group. Overall survival was significantly improved in the regorafenib group compared with the lomustine group, with a median overall survival of 7·4 months (95% CI 5·8-12·0) in the regorafenib group and 5·6 months (4·7-7·3) in the lomustine group (hazard ratio 0·50, 95% CI 0·33-0·75; log-rank p=0·0009). Grade 3-4 treatment-related adverse events occurred in 33 (56%) of 59 patients treated with regorafenib and 24 (40%) of 60 with lomustine. The most frequent grade 3 or 4 adverse events related to regorafenib were hand-foot skin reaction, increased lipase, and blood bilirubin increased (in six [10%] of 59 patients each). In the lomustine group, the most common grade 3 or 4 adverse events were decreased platelet count (eight [13%] of 60 patients), decreased lymphocyte count (eight [13%]), and neutropenia (seven [12%]). No death was considered by the investigators to be drug related. INTERPRETATION: REGOMA showed an encouraging overall survival benefit of regorafenib in recurrent glioblastoma. This drug might be a new potential treatment for these patients and should be investigated in an adequately powered phase 3 study. FUNDING: Veneto Institute of Oncology and Bayer Italy.

Defining a prognostic score based on O6-methylguanine-DNA methyltransferase cut-off methylation level determined by pyrosequencing in patients with glioblastoma multiforme.

PURPOSE: Epigenetic variations in the O6-methylguanine-methyltransferase gene had been widely associated with a favorable impact on survival in patients affected by glioblastoma multiforme (GBM). Aim of this study is to explore a scoring system based on the gene promoter methylation in order to predict patients' prognosis. METHODS: A series of 128 patients with GBM was retrospectively analyzed. A training set and a validations set were then generated. The methylation level of CpGi from 74 to 83 was determined by pyrosequencing. In accordance to previous literature, each island was assigned with 1 point if the corresponding methylation level was higher than 9%. The sum consisted in a score that went from 0 (all CpGi < 9%) to 10 (all CpGi ≥ 9%). A threshold capable to detect a favorable outcome (overall survival, OS > 24 months) was identified by ROC analysis. RESULTS: Median OS and follow-up were 14 and 32.6 months respectively. Among the total population, 35% of the pts had a score of 0, while 29% had a score of 10. A score ≥ 6 was associated with a favorable prognosis also when corrected for age (> 70 vs. ≤ 70 years) and ECOG performance status (0-1 vs. 2-3). Similar results were observed also in terms of PFS. Results were consistent in the training and in the validation set. CONCLUSIONS: The present manuscript explored a novel scoring system capable to take into consideration the methylation status of each single CpGi, capable to better predict prognosis in GBM patients.

MGMT pyrosequencing-based cut-off methylation level and clinical outcome in patients with glioblastoma multiforme.

AIM: MGMT promoter methylation has been associated with improved survival in glioblastoma multiforme treated with temozolomide. However, there is no consensus on specific cut-off levels of methylation. The aims of the study were to explore the prognostic impact of MGMT methylation status and to analyze the role of specific cut-off values. MATERIALS & METHODS: We analyzed 108 glioblastoma multiforme patients treated between 2008 and 2013 stratified according to three pyrosequencing-based quantitative methylation in: unmethylated (methylation <9%), intermediate (9-29%) and highly methylated (>29%). RESULTS: The three-class stratification has a prognostic impact (median progression-free survival: 7.97, 11.6 and 15 months respectively; p = 0.004; median OS: 13.2, 15.8 and 19.5 months, respectively; p = 0.0002), especially in patients exposed to temozolomide. CONCLUSION: Our study confirmed that the independent prognostic role of MGMT methylation status. An average level of methylation between all investigated CpGs of 9% may help discriminating between methylated and unmethylated tumors.

Combining Clinical and Molecular Data to Predict the Benefits of Carmustine Wafers in Newly Diagnosed High-Grade Gliomas.

PURPOSE OF REVIEW: The purpose of this study was to retrospectively evaluate the use of carmustine wafers (CWs) in the management of high-grade gliomas (HGGs). The data from our monoinstitutional series was compared with studies reported in the literature. Special emphasis was placed on the evaluation of side effects and the analysis of extent of resection and molecular profile as risk factors. RECENT FINDINGS: The implantation of CWs into the resection cavity during HGG treatment to deliver localized chemotherapy, followed by the Stupp protocol, remains debated in a clinical setting, largely due to the lack of appropriate phase III studies. Given the high expense and poorly characterized side effects associated with CW treatment, identification of patients most likely to benefit from this therapy could be clinically relevant. CWs may represent an effective and safe first-line treatment for patients with HGG that exhibit complete tumor resection and harboring a methylated MGMT promoter. Our investigation showed a much larger group of patients exhibiting long-term survival (> = 36 months), strongly supporting a potential survival benefit conferred via CW treatment. The pre-surgical definition of the MGMT promoter status could be of clinical use in identifying "good responders" to CW implantation.

Predictors of survival and effect of short (40 Gy) or standard-course (60 Gy) irradiation plus concomitant temozolomide in elderly patients with glioblastoma: a multicenter retrospective study of AINO (Italian Association of Neuro-Oncology).

The efficacy of temozolomide (TMZ) plus radiation therapy (RT) in elderly patients with glioblastoma is unclear. We performed a large multicenter retrospective study to analyze prognostic factors and clinical outcome in these patients. Inclusion criteria were age ≥65 years, newly histologically confirmed glioblastoma, ECOG PS 0-2, adjuvant treatment with RT plus TMZ. We enrolled 237 patients; the average age was 71 and ECOG PS was 0-1 in 196 patients; gross total resection was performed in 174 cases. MGMT was analyzed in 151 persons and was methylated in 56 %. IDH1 was assessed in 100 patients and was mutated in 6 %. Seventy-one patients were treated with RT 40 Gy and 166 with RT 60 Gy. Progression-free survival and overall survival (OS) were 11.3 and 17.3 months, respectively. Overall survival was 19.4 vs 13.8 months for patients treated with RT 60 Gy and 40 Gy (p = 0.02); OS was 17.7 versus 16.1 months for patients treated with gross total resection vs partial surgery (p = 0.02); OS was 21.2 versus 13.6 months for methylated and unmethylated MGMT (p < 0.001). On multivariate analysis, gross total resection, RT 60 Gy, methylated MGMT and ECOG PS 0-1 were independent predictors of longer survival. Twenty-five patients (10 %) had grade 3-4 haematological toxicity during the concomitant treatment. We showed that, in elderly patients in good clinical condition treated with concomitant treatment, standard-course irradiation might be more effective than short-course irradiation. Methylated MGMT remains the most important prognostic factor.

Adopting integrated care pathways in non-small-cell lung cancer: from theory to practice.

INTRODUCTION: Integrated care pathways (ICPs) have been proposed as effective strategies for quality improvement. To date, limited data are available that detail the methodology to design an optimal care pathway for patients with non-small-cell lung cancer (NSCLC). The main aim of this study was to assess the quality of health care delivered to lung cancer patients referred to a hub university hospital. METHODS: All professionals involved with the management of NSCLC patients, in cooperation with health care researchers, identified 11 quality indicators and associated benchmarks. These were used to estimate the quality and efficiency of health care delivered to a cohort of 175 NSCLC patients. RESULTS: The gap between "desired" and "actual" performance has been measured by benchmarking current practice against key quality indicators. Diagnostic workup, multidisciplinary team care and medical treatment of advanced disease have emerged as areas of good performance. Conversely, the management of early-stage disease offers room for improvement, in terms of both accuracy of nodal staging and surgical timeliness. CONCLUSIONS: Analyzing the process of caring for NSCLC patients is feasible and offers room for improvement. Acquired knowledge may be shared with hospital administrators, guide the revision of ICPs, and enable the delivery of consistent, high-quality clinical standards.

Phase II study of irinotecan and docetaxel in patients with previously treated non-small cell lung cancer: an Alpe-Adria Thoracic Oncology Multidisciplinary group study (ATOM 007).

This study was designed to evaluate the activity and tolerability of irinotecan and docetaxel in patients with previously treated non-small cell lung cancer (NSCLC). Eligibility included recurrent or progressive NSCLC, previous chemotherapy, age > or = 18 years, ECOG PS < or = 2. Treatment consisted of irinotecan (160 mg/m2 i.v.), followed by docetaxel (65 mg/m2 i.v.) on day 1 of a 21-day cycle, for a maximum of 6 cycles. Forty patients were enrolled. Median age was 60 years and median ECOG PS was 1. All patients were evaluable for toxicity and 31 (78%) were evaluable for response. A total of 125 cycles was administered (median, 3; range, 1-6). Most common grade 3-4 toxicities were neutropenia (62%), neutropenic fever (22%), and diarrhea (32%). Response rate was 10%; a further 40% of patients achieved stable disease. All responses were observed in patients with ECOG PS < or = 1, age <70 years, and who had received only one prior chemotherapy regimen. Median time to progression was 2.8 months and median survival was 7.4 months. Because of significant toxicity and limited activity, further investigation of irinotecan plus docetaxel in second line NSCLC is not recommended.

Sequential chemotherapy with paclitaxel plus cisplatin, followed by vinorelbine, followed by gemcitabine in advanced non-small cell lung cancer: an Alpe-Adria Thoracic Oncology Multidisciplinary group study (ATOM 001).

Aim of this study was to determine the activity and toxicity of a sequential chemotherapy regimen in advanced non-small cell lung cancer (NSCLC). Fifty-one previously untreated stage IIIB/IV NSCLC patients were enrolled to receive two cycles of cisplatin plus paclitaxel (80/175 mg/m(2) every 21 days), followed by two cycles of vinorelbine (30 mg/m(2) on days 1 and 8 every 21 days), followed by two cycles of gemcitabine (1000 mg/m(2) on days 1, 8, and 15 every 28 days). Forty-one patients (82%) completed the planned six cycles. Grade 3-4 neutropenia was the major toxicity (41% of patients) and it was mainly associated with vinorelbine administration. Response rate after cisplatin plus paclitaxel was 18%; this percentage increased to 41% after vinorelbine, and it reached 43% upon completion of the entire six cycle treatment program. Median survival time was 14.4 months, 1-year survival rate was 53%, and 2-year survival rate was 18%. Median time to disease progression was 6.8 months. This sequential chemotherapy regimen is feasible and active in patients with advanced NSCLC. This pilot experience provides the basis for an ongoing randomized phase III trial comparing our sequential regimen versus cisplatin plus gemcitabine.
