Efficacy and Safety of Lanreotide Autogel and Temozolomide Combination Therapy in Progressive Thoracic Neuroendocrine Tumors (Carcinoid): Results from the Phase 2 ATLANT Study.

INTRODUCTION: Lanreotide autogel (LAN) and temozolomide (TMZ) are guidelines-recommended monotherapies for thoracic neuroendocrine tumors (carcinoids; T-NETs), but prospective data for both combined and monotherapies are lacking. ATLANT (NCT02698410) evaluated efficacy and safety of LAN/TMZ in progressive T-NETs. METHODS: ATLANT was a 12-month, Italian, phase 2, single-arm, open-label, multicenter pilot study. Eligible patients had unresectable, locally advanced/metastatic, well-/moderately differentiated T-NETs with radiological progression. Patients received subcutaneous LAN 120 mg every 28 days and oral TMZ 250 mg/day for 5 consecutive days every 28-day cycle. Main endpoints are disease control rate (DCR) at 9 months (primary; investigator-assessed), median progression-free survival (PFS), biomarkers, and safety. RESULTS: The number of patients was 40; 60% were male. Primary tumor site was lung (90%) and thymus (10%). Carcinoid type was typical (20.0%) and atypical (52.5%). DCR at 9 months was 35.0% (95% confidence interval (CI) 20.63-51.68; nonacceptability threshold ≤10%, p < 0.0001; not significantly above clinically relevant threshold ≥30%, p = 0.2968). DCR between 7.5 and 10.5 months (sensitivity analysis) was 45.0% (95% CI: 29.26-61.51) and clinically relevant (p = 0.0320 at ≥30% threshold). Median PFS was 37.1 (95% CI: 24.1-52.9) weeks. No association was observed between biomarker variations (chromogranin A, neuron-specific enolase, somatostatin receptor type-2, Ki-67, 6-O-methylguanine-DNA-methyl-transferase) and DCR or PFS. Most patients (97.5%) had treatment-emergent adverse events (TEAEs); 72.5% had treatment-related TEAEs. TEAEs were mainly grade 1/2. No unanticipated TEAEs were reported. CONCLUSIONS: This study showed that the LAN/TMZ combination has promising efficacy in progressive T-NETs, and was well tolerated. Larger studies are warranted to support the clinical benefits of LAN/TMZ in patients with T-NETs.

Lynch syndrome-associated lung cancer: pitfalls of an immunotherapy-based treatment strategy in an unusual tumor type.

Lynch syndrome is a hereditary cancer predisposition syndrome caused by germline alterations in mismatch repair (MMR) genes leading to increased risk of colon cancer as well as other cancer types. Non-small cell lung cancer (NSCLC) is not among typical Lynch syndrome-associated tumors: pembrolizumab, an immune checkpoint inhibitor, is actually approved for the treatment of NSCLC patients and represents a promising treatment option for patients with advanced metastatic MMR-deficient cancer, regardless of tumor origin. This case report describes the clinical presentation and management of a 74-year-old female with a history of rectal adenocarcinoma and ovarian cancer, who has a documented frameshift pathogenic variant in the exon 8 of MSH6 gene and an intronic variant in the BRCA2 gene (classified as a variant of uncertain significance), affected by NSCLC with brain metastases. Despite these premises, the patient was treated with pembrolizumab and she did not benefit from this kind of treatment.

Questioning the prognostic role of BAP-1 immunohistochemistry in malignant pleural mesothelioma: A single center experience with systematic review and meta-analysis.

INTRODUCTION: The prognostic role of BRCA1 associated protein-1 (BAP1) expression in malignant pleural mesothelioma (MPM) is a matter of debate. We aimed to clarify whether MPM patients with loss of BAP1 expression have better overall survival (OS) compared to BAP1 positive patients. METHODS: BAP1 immunohistochemical staining of tumor samples from 60 MPM patients treated at our institution with first-line chemotherapy was evaluated. A systematic literature search was also performed. Only cohort studies that investigated BAP1 by immunohistochemistry (IHC) and reported hazard ratio (HR) values for OS obtained through multivariate analysis (or adjusted for histotype) were considered. A dataset comprising 638 MPM patients was added to our cohort and included in the meta-analysis. RESULTS: In our cohort, 23 samples (38 %) were BAP1 positive/retained (≥1 %) and 37 samples (62 %) were BAP1 negative/loss. BAP1 loss was associated with epithelioid histotype (p 0.01). Median OS times were 14.8 months (95 % CI: 10.7-29.3) and 18.1 months (95 % CI: 11.2-25.8) for negative and positive BAP1 expression, respectively (p 0.2). At multivariate analysis, again no differences were observed among the two groups (p 0.81). Similarly, the meta-analysis consisting of 698 patients showed no difference in terms of OS according to BAP1 status (HR 1.11; 95 % CI, 0·76-1·61; p 0.60). CONCLUSIONS: BAP1 expression is not an independent prognostic factor for MPM patients and it should not be considered without taking into account tumor histotype. Future studies should investigate its predictive role in patients treated with new emerging therapies such as immunotherapy.

The role of angiogenetic single-nucleotide polymorphisms in thymic malignancies and thymic benign lesions.

BACKGROUND: We previously showed that selected single-nucleotide-polymorphisms (SNPs) of genes involved in angiogenesis influence the aggressiveness of thymic epithelial tumors (TETs). This study analyzes their role in TETs and in thymic benign lesions, in order to investigate potential correlation with risk and outcome. METHODS: Genomic DNA was extracted from paraffin-embedded tissue of 92 patients, undergoing surgery at our Institution. We investigated by Real-Time PCR the SNPs of the following genes: platelet-derived growth factor receptor-α (PDGFRα), hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor A (VEGF-A), vascular endothelial growth factor receptor-2 and 3 (VEGF-2, VEGFR-3), excision repair cross-complementation group-1 (ERCC1). RESULTS: Fifty-seven TETs and 35 thymic benign lesions were included into the study. Frequency of SNPs was as follows: rs2057482 C, rs11158358 C and rs11549465 C polymorphisms of HIF1-a: thymomas < general population (P=0.008, P=0.007, and P=0.044 respectively). HIF1-a alleles: general population > study groups, rs1951795C SNP (P=0.026 for benign lesions and P=0.0007 for thymomas), rs10873142T SNP (P=0.008 and P=0.001 respectively), rs12434438 A SNP (P=0.034 and P=0.0007) and rs2301113A SNP (P=0.027 and P=0.010). rs699947C polymorphism of VEGF-A: benign lesions > general population (P=0.012). CONCLUSIONS: This is the first study investigating the angiogenetic polymorphisms in thymic benign lesions and TETs. SNPs analysis may represent a further asset in identification of patients who could benefit from anti-angiogenetic therapy.

Prognostic relevance of programmed cell death protein 1/programmed death-ligand 1 pathway in thymic malignancies with combined immunohistochemical and biomolecular approach.

BACKGROUND: The aim of the study was to investigate Programmed cell Death protein 1 (PD-1) and Programmed Death-Ligand 1 (PD-L1) and their mRNA expression in thymic epithelial tumors (TETs). RESEARCH DESIGN AND METHODS: We analyzed 68 samples of formalin-fixed paraffin-embedded tissue (63 thymomas and 5 thymic carcinomas). PD-1 and PD-L1 protein expression were evaluated by immunohistochemistry, and mRNA expression was evaluated by real-time PCR. RESULTS: M/F ratio was 33/35, and median age was 60.5 years. Twenty patients had Myasthenia Gravis (MG). In the subgroup with large tumors (>5 cm), PD-L1 mRNA overexpression was significantly associated with worse prognosis vs. patients with no mRNA overexpression (p = 0.0083) and simultaneous PD-L1 immunostaining (>1%); PD-L1 mRNA overexpression was significantly associated with worse prognosis, respect to patient with PD-L1 negative immunostaining, and no PD-L1 mRNA overexpression (p = 0.0178). The elderly patients (>60 years) with large tumors showed worse prognosis (p = 0.0395). PD-L1 immunostaining (>50%) resulted to be significantly associated with MG. CONCLUSIONS: Our data suggest the potential involvement of the PD-1 and PD-L1 pathway in TETs' progression. According to our results, it may be helpful to design future trials with anti-PD-1 drugs to establish high-risk patients after surgery.

Systemic treatment for lung carcinoids: from bench to bedside.

In the huge spectrum of lung neuroendocrine neoplasms, typical and atypical carcinoids should be considered as a separate biological entity from poorly differentiated forms, harboring peculiar molecular alterations. Despite their indolent behavior, lung carcinoids correlate with a worse survival. To date, only limited therapeutic options are available and novel drugs are strongly needed. In this work, we extensively reviewed scientific literature exploring available therapeutic options, new molecular targets and future perspectives in the management of well differentiated neoplasms of bronchopulmonary tree. Systemic therapy represents the main option in advanced and unresectable disease; accepted choices are somatostatin analogs, peptide receptor radionuclide therapy, everolimus and chemotherapy. To date, an univocal treatment strategy has not been identified yet, thus tailored therapeutic algorithms should consider treatment efficacy as well as safety profiles. Several molecular alterations found in carcinoid tumors might act as molecular targets leading to development of new therapeutic options. Further studies are necessary to identify new potential "druggable" molecular targets in the selected subset of low-grade lung carcinoids. Furthermore, evaluating the available therapies in more homogeneous population might improve their efficacy through a perfect tailoring of treatment options.

Listening understanding and acting (lung): focus on communicational issue in thoracic oncology.

BACKGROUND: In the field of oncological assistance, nowadays we have to deal with a complex scenario where patients got used to obtain a huge amount of information through internet or social media and to apply them in performing their health-related decisions. This landscape requires that clinicians become able to handle therapeutical approaches and adequate skills in communication tools to satisfy the current needs. Our project aimed to build a communication model based on clinical oncologists' real experiences in order to find a simple way to share with patients all the innovative therapeutical opportunities today available in lung cancer. The final goal is to design a flexible and personalized model adaptable to clinician's personal characteristics and to the specific patient he is facing. We applied both traditional educational tools and innovative techniques in order to make the results effective and applicable to support peer learning. METHODS: The first step consisted in a Board synthesized the definition of the diagnostic process, the identification of treatment strategies and any potential communication barrier clinicians may face dealing with patients. The second step consisted in teamwork including a theoretical part and a training part. In the third step we produce five training videos and video interviews regarding communication praxis and a "Small communication manual". The last step consisted in the publication of the produced material on website and its diffusion through the social media. RESULTS: In medicine, the universal application of a single model of communication does not represent the optimal solution. By contrary, the availability of simple and practical suggestions to improve the communicative style could allow clinicians to abandon stereotyped formulas identically repurposed to all patients. The "from bottom to top" training, starting from real-life to take advantage of the clinician's experience, give the clinicians the possibility to meditate about their own communicative style and to train in the context of a protected environment. Applying these rules, we design an effective communication model, based on healthcare humanization, which could represent a fundamental support for the patient in order to be gently driven by the clinician to the most appropriate therapeutical choice, balancing efficacy and quality of life. The relational training may improve the quality of clinician-patient communication and could be widespread to other clinicians through the media. CONCLUSIONS: Considering the innovative therapeutical options available, particularly for lung cancer patients, and the increasing access of health-related information through internet or social media the clinician-patient communication has become crucial to support the achievement of the most appropriate therapeutical choice for the patient, facing the intricate illness experience. Building a shareable and easy-to-apply communication model represents a challenge aimed to help clinicians and including technology not as a threat, but as a positive tool.

Sequential chemotherapy with cisplatin/gemcitabine (CG) followed by mitoxantrone/methotrexate/mitomycin (MMM) in patients with malignant pleural mesothelioma. A multicenter Italian Phase II Study (SITMP1).

PURPOSE: We performed a multicenter phase II trial to evaluate the impact on the activity, efficacy, symptom control and safety of using two active regimens in a sequential schedule (cisplatin/gemcitabine followed by mitoxantrone/methotrexate/mitomycin) as first-line chemotherapy for unresectable malignant pleural mesothelioma (MPM). PATIENTS AND METHODS: A total of 54 patients received cisplatin 75 mg/m(2) on day 1 and gemcitabine 1,200 mg/m(2) on days 1 and 8, every 3 weeks for four courses (CG regimen) followed by mitoxantrone 10 mg/m(2) on day 1, methotrexate 35 mg/m(2) on day 1 and mitomycin 7 mg/m(2) on day 1, every 3 weeks with mitomycin in alternate cycles for four courses (MMM regimen). RESULTS: We observed 3 complete responses (CRs) (5.6%) and 13 partial responses (PRs) (24.0%), with an overall response rate (ORR) of 29.6% (95% confidence interval, 17-42%), 33 stable disease (SD) (61.1%) and 5 progressive disease (PD) (9.2%). Median time to progression (TTP) was 9.5 months (range, 2-23). Median overall survival (OS) was 13 months (range, 3-33); 1-year survival rate was 63%. The treatment produced a good symptom control, with an improvement during chemotherapy in dyspnea and pain in 52.9 and 48.3% of patients, respectively. The major toxicity observed was hematological. Grades 3-4 NCI-CTC v 2.0 toxicity with the CG regimen included: neutropenia (11.1%), anemia (1.9%), thrombocytopenia (7.4%), vomiting (11.1%) and with the MMM regimen: neutropenia (35.2%), anemia (5.5%), thrombocytopenia (7.4%) and stomatitis (1.9%). CONCLUSION: This phase II study with the sequential approach of two active regimens showed a good disease control in MPM, with symptom improvement and only mild toxicity.

Economic sustainability of anti-PD-1 agents nivolumab and pembrolizumab in cancer patients: Recent insights and future challenges.

Anti-programmed death (PD)-1 agents pembrolizumab and nivolumab have recently obtained enthusiastic results in terms of progression-free survival (PFS), overall survival (OS) and tolerability in cancer patients. Despite these promising data, the high cost of these agents needs careful consideration. Indeed, the evaluation of cost-effectiveness analysis (CEA) and quality-adjusted life year (QALY), as well as different drug reimbursement modalities, will represent fundamental tools in order to guarantee the economic sustainability of health system and the access to care for all cancer patients. In this review, we discussed the recent results obtained by immunotherapy in cancer patients and we evaluated the economic impact of recently approved nivolumab and pembrolizumab in patients with advanced melanoma, non-small cell lung cancer (NSCLC) and renal cell carcinoma (RCC).

Hormonal receptors in lung adenocarcinoma: expression and difference in outcome by sex.

BACKGROUND: Lung cancer seems to have different epidemiological, biomolecular and clinical characteristics in females than in males, with a better prognosis for women. The aim of the study is to determine gender differences in lung adenocarcinoma in terms of androgen (AR), estrogen (ER)α and progesterone (PgR) receptors expression and their impact on outcome. RESULTS: Overall survival was significantly better in ERα and in PgR positive lung adenocarcinoma patients (median survival 45 vs. 19 months).Eight out of 62 patients showed positive expression of nuclear (n) AR and 18 of cytoplasmic (c) AR with a significantly better survival (49 vs. 19 and 45 vs. 19 months, respectively). There was a significant difference in survival between patients with vs. without c-AR expression (30 vs. 17 months). Finally, in the subgroup of women, median survival was greater in positive expression of c-AR than for women with negative c-AR (45 vs. 21 months). MATERIALS AND METHODS: We conducted an analysis on a cohort of 62 patients with advanced NSCLC treated at our institution. We investigated the immunohistochemical expression of n/c AR, ERα and PgR in 62 NSCLC and we correlated it with patients' clinic-pathologic characteristics and with prognosis. CONCLUSIONS: Our results showed that the positive expression of one hormonal receptor could represent a prognostic factor.Furthermore our study suggests that AR should become object of close examination in a larger series of lung adenocarcinoma patients, also for selection of the patients with best prognosis that can perform more chemotherapy lines.

Impact of VEGF, VEGFR, PDGFR, HIF and ERCC1 gene polymorphisms on thymic malignancies outcome after thymectomy.

We aimed to analyze genotypes of VEGF-A, VEGFR2, Flt4, PDGFRα, HIF-1α and ERCC1 and their correlation with thymic tumor risk and patient outcome. DNA of 57 consecutive patients (43 thymomas and 14 thymic carcinomas) who underwent total thymectomy at our Institution was extracted from paraffin-embedded tissue. We selected polymorphisms in the following genes:HIF1-α (rs2057482T > C, rs1951795A > C, rs2301113C > A, rs10873142C > T, rs11158358G > C, rs12434438G > A, rs11549465C > T, rs11549467G > A), VEGF-A (rs2010963G > C, rs699947A > C), VEGFR-2 (rs2305948C > T, rs1870377T > A), VEGFR-3 (rs307826T > C, rs307821C > A), PDGFR-α (rs35597368C > T) and ERCC1 (rs11615A > G). Gene polymorphisms were determined by Real-Time PCR using TaqMan assays. As compared to the general population, the allele frequency of PDGFR-α rs35597368T was significantly higher (95% vs. 87%, p = 0.036), while the frequency of alleles HIF1-α rs2057482C (78% vs. 90%), rs1951795C (69% vs. 87%), rs2301113A (70% vs. 83%), rs10873142T (70% vs. 87%), rs11158358C (75% vs. 88%), rs12434438A (67% vs. 84%) were significantly lower. VEGFR-3 rs307821C frequency was significantly higher in thymomas vs. thymic carcinomas (79% vs. 72%, p = 0.0371). The following factors were significantly correlated with a longer overall survival: VEGFR-3 rs307826C, VEGFR-2 rs1870377A, PDGFR-α rs35597368T/C, HIF1-α rs2301113C, rs2057482C/T, rs1951795C, rs11158358G/C and rs10873142T/C, ERCC1 rs11615A (p < 0.05). Our results suggest, for the first time, that PDGFR-α, HIF-1α and VEGFR-3 SNPs are associated with thymic cancer risk and survival.

Randomized, multicenter, phase II study of gemcitabine plus cisplatin versus gemcitabine plus carboplatin in patients with advanced non-small cell lung cancer.

BACKGROUND: We conducted a phase II randomized study to assess the efficacy, with response as the primary endpoint, and the toxicity of gemcitabine/cisplatin (GP) and gemcitabine/carboplatin (GC) in patients with advanced non-small cell lung cancer (NSCLC). METHODS: Patients were randomized to GP (gemcitabine 1200 mg/m(2), days 1 and 8 plus cisplatin 80 mg/m(2) day 2) or GC (gemcitabine 1200 mg/m(2), days 1 and 8 plus carboplatin AUC=5 day 2). Cycles were repeated every 3 weeks. RESULTS: Sixty-two patients were randomized to GP and 58 to GC. A total of 533 cycles were delivered (264 GP, 269 GC), with a median of four cycles/patient. The objective response rate was 41.9% (95% C.I., 29.6-54.2%) for GP and 31.0% (95% C.I., 18.2-42.8%) for GC (P=0.29). No significant differences between arms were observed in median survival (10.4 months GP, 10.8 months GC) and median time to progression (5.4 months GP, 5.1 months GC). Both regimens were very well tolerated with no statistical differences between arms in grade 3/4 toxicities. When all toxicity grades were combined, emesis, neuropathy and renal toxicity occurred more frequently on the GP arm (P<0.005). CONCLUSIONS: GC arm did not provide a significant difference in response rate compared with GP arm, with better overall tolerability. Carboplatin could be a valid alternative to cisplatin in the palliative setting.

In vitro study of farnesyltransferase inhibitor SCH 66336, in combination with chemotherapy and radiation, in non-small cell lung cancer cell lines.

K-ras alterations have been reported in 20-30% of non-small cell lung cancer (NSCLC) and represent a suitable target for the development of novel anticancer agents, such as Farnesyl transferase inhibitors (FTi), a new class of agents inhibiting the post-translational modification of the K-ras proteins. The effectiveness of FTi SCH66336 in inhibiting cell proliferation and deranging cell cycle of NSCLC cell lines as well as its interaction with chemotherapy or radiation have been evaluated. The activity of FTi SCH66336, alone or in combination with paclitaxel, gemcitabine, and radiotherapy, was examined in 3 cell lines, A-549, LX-1 and CaLu-6, by colorimetric MTT assay. Cell cycle perturbation and apoptosis were also assessed by cytofluorimetric analysis. The activity of SCH 66336 was found to be concentration- and time-dependent. The effect of SCH 66336, as demonstrated by cell growth recovery experiments, resulted cytostatic and it was superimposable in both cell lines bearing 2 different K-ras mutations (A-549 and LX-1) and in K-ras wild-type Ca-Lu-6. In all cell lines the combination of SCH 66336 and paclitaxel resulted in a synergism of action when SCH 66336 followed paclitaxel treatment, whereas, antagonism was found when SCH 66336 preceded paclitaxel treatment. No significant synergism or addition with SCH 66336 followed by radiation treatment was noted. Different cell cycle phase blocks at various drug concentrations were observed. In conclusion, SCH 66336 displays concentration-dependent cytostatic antitumour activity and schedule-dependent synergy with 2 commonly used anticancer agents in NSCLC cell lines. Further clinical testing of these combinations is warranted.

Preoperative maximum oxygen consumption is associated with prognosis after pulmonary resection in stage I non-small cell lung cancer.

BACKGROUND: The objective of this investigation was to evaluate whether maximum oxygen consumption (VO2max) is a reliable prognostic factor after lung resection for pathologic stage I non-small cell lung cancer (NSCLC). METHODS: Observational analysis of 157 patients undergoing pulmonary lobectomy or segmentectomy for pathologic stage I (T1 or T2-N0 only) NSCLC, with preoperative measurement of Vo2max and complete follow-up (2006-2011). Survival was calculated by the Kaplan-Meier method. The log-rank test was used to assess differences in survival between groups. The relationships between survival and several baseline and clinical variables were determined by Cox multivariate analyses. RESULTS: The median follow-up time was 40 months. The average preoperative Vo2max was 16.1 mL/kg · min and 69% of predicted value. Sixty-two (40%) patients had a Vo2max below 60%. The median and 5-year overall survivals of patients with preoperative Vo2max above 60% were significantly longer than in those with Vo2max below 60% (median not reached vs 48 months: 73% vs 40%, p=0.0004). Cox regression model showed that an age older than 70 years (p=0.005, hazard ratio 2.3) and Vo2max below 60% (p=0.001, hazard ratio 2.4) were independent prognostic factors significantly associated with overall survival. Cancer-specific survival was also longer in patients with Vo2max above 60% (81% vs 61%, p=0.01). CONCLUSIONS: Exercise tolerance may influence the physiologic outcomes associated with cancer that can potentially affect survival. Physical rehabilitation aimed at improving exercise tolerance can possibly improve the long-term prognosis after operations for lung cancer.

Thymic neoplasms: an update on the use of chemotherapy and new targeted therapies. A literature review.

Thymic malignancies represent a wide range of clinical, histological and molecular entities, with probably considerable heterogeneity even among tumors of the same histotype. Systemic chemotherapy with cisplatin-based regimens continues to represent the standard of care in metastatic or inoperable refractory/recurrent diseases and ADOC regimen (including cisplatin, doxorubicin, vincristine and cyclophosphamide) demonstrated the longer overall response rate and median survival in the first line setting, although no randomized trial is available; and there is still a lack of standard treatment after first-line failure. To date research efforts are focused on translational studies on molecular pathways involved in thymic tumors carcinogenesis, aimed to better understand and predict the efficacy of chemotherapy and targeted therapy. Recent molecular characterization includes identification of a number of oncogenes, tumor suppressor genes, chromosomal aberrations, angiogenic factors, and tumor invasion factors involved in cellular survival and proliferation and in tumor growth. The use of biologic drugs is currently not recommended in a routine practice because there are limited data on their therapeutic role in thymic epitelial tumors. Because of the lack of data from adequate-sized, prospective trials are required for validation and the enrolment of patients with advanced disease into available clinical trials has to be encouraged.

Development of a patient-centered aggregate score to predict survival after lung resection for non-small cell lung cancer.

OBJECTIVE: The objective of this analysis was to develop a survival aggregate score (SAS), including objective and subjective patient-based parameters, and assess its prognostic role after major anatomic resection for non-small cell lung cancer. METHODS: A total of 245 patients underwent major lung resections for non-small cell lung cancer with preoperative evaluation of quality of life (Short-Form 36v2 survey) and complete follow-up. The Cox multivariable regression and bootstrap analyses were used to identify prognostic factors of overall servival, which were weighted to construct the scoring system and summed to generate the SAS. RESULTS: Cox regression analysis showed that the factors negatively associated with overall survival and used to construct the score were 36-item short-form health survey physical component summary score less than 50 (hazard ratio [HR], 1.7; P = .008), aged older than 70 years (HR, 1.9; P = .002), and carbon monoxide lung diffusion capacity less than 70% (HR, 1.7; P = .01). Patients were grouped into 4 risk classes according to their SAS. The 5-year overall survival was 78% in class SAS0, 59% in class SAS1, 42% in class SAS2, and 14% in class SAS3 (log-rank test, P < .0001). SAS maintained its association with overall survival in patients with stages pT1 (log-rank test, P = .01), pT2 (log-rank test, P = .02), or pT3-4 (log-rank test, P = .001), and in those with stages pN0 (log-rank test, P = .0005) or pN1-2 (log-rank test, P = .02). The 5-year cancer-specific survival was 83% in class SAS0, 71% in class SAS1, 63% in class SAS2, and 17% in class SAS3 (log-rank test, P < .0001). CONCLUSIONS: This system may be used to refine stratification of prognosis for clinical and research purposes.

Preoperative quality of life predicts survival following pulmonary resection in stage I non-small-cell lung cancer.

OBJECTIVES: The objective of this study was to assess the prognostic role of preoperative quality of life (QoL) in patients operated on for early-stage non-small-cell lung cancer (NSCLC). METHODS: This is an observational analysis of 131 consecutive patients (2003-08) submitted to pulmonary lobectomy and systematic nodal dissection for pathological pT1N0 or pT2N0 stages NSCLC with a complete follow-up (median 40 months). QoL was measured by the Short Form 36v2, a multidimensional survey assessing eight domains and two composite scales (physical component score [PCS] and mental component score [MCS]). Survival was calculated by the Kaplan-Meier method. The log-rank test was used to assess differences between groups. The relationships between survival and QoL composite scales were determined by Cox proportional hazards regression analysis adjusting for the effect of several baseline and clinical variables. PCS and MCS were categorized according to their values greater or lower than 50 percentiles (general population norms). RESULTS: Fifty-three (40%) patients had PCS <50 and 71 (54%) had MCS <50. Results from physical functioning (P = 0.03) and general health (P = 0.03) scales were directly associated with survival. Multivariable regression showed that significant factors associated with overall survival were age >70 (hazard ratio [HR] 2.4, 95% confidence interval [95% CI] 1.2-4.8, P = 0.01) and PCS <50 (HR 2.3, 95% CI 1.4-4.4, P = 0.01). MCS, pT stage, histology, forced expiratory volume in 1 s, DLCO were not associated with prognosis. Patients with PCS >50 lived longer than those with PCS <50 (5-year overall survival 79 vs 49%, P = 0.01), in both pT1 (5-year overall survival 80 vs 49%) and pT2 stages (5-year overall survival 78 vs 48%). Cancer-specific 5-year survival was better in patients with a preoperative PCS >50 compared with those with PCS <50 (89 vs 73%, P = 0.05). Deaths due to cancer recurrence were similar in patients with PCS <50 and >50 (55 vs 53%, P = 0.9). CONCLUSIONS: The physical component of QoL was associated with overall and cancer-specific survivals in patients operated on for early-stage NSCLC. Supportive interventions aimed at improving the perception of physical well-being should be tested to verify whether they can improve long-term prognosis after lung cancer surgery.

State of the art for cardiotoxicity due to chemotherapy and to targeted therapies: a literature review.

Cardiotoxicity is a common complication of many anti-cancer agents and it remains a major limitation, strongly impacting the quality of life and the overall survival, regardless of the oncologic prognosis. Cardiotoxicity may occur during or shortly after treatment (within days or weeks), or it may become evident months, and sometimes years, after completion of chemotherapy. Cardiotoxicity associated with cancer therapies can range from asymptomatic subclinical abnormalities, including electrocardiographic changes and temporary left ventricular ejection fraction decline, to life-threatening events such as congestive heart failure or acute coronary syndromes. The aim of this review is to summarize potential cancer chemotherapeutics-related cardiovascular toxicities in adult cancer-patients and to suggest monitoring and treatment options for each agent, that can serve as a tool in the clinical practice.

Novel small molecule EGFR inhibitors as candidate drugs in non-small cell lung cancer.

In the last decade, better understanding of the role of epidermal growth factor receptor in the pathogenesis and progression of non-small cell lung cancer has led to a revolution in the work-up of these neoplasms. Tyrosine kinase inhibitors, such as erlotinib and gefitinib, have been approved for the treatment of non-small cell lung cancer, demonstrating an improvement in progression-free and overall survival, particularly in patients harboring activating EGFR mutations. Nevertheless, despite initial responses and long-lasting remissions, resistance to tyrosine kinase inhibitors invariably develops, most commonly due to the emergence of secondary T790M mutations or to the amplification of mesenchymal-epithelial transition factor (c-Met), which inevitably leads to treatment failure. Several clinical studies are ongoing (http://www.clinicaltrials.gov), aimed to evaluate the efficacy and toxicity of combined approaches and to develop novel irreversible or multitargeted tyrosine kinase inhibitors and mutant-selective inhibitors to overcome such resistance. This review is an overview of ongoing Phase I, II, and III trials of novel small molecule epidermal growth factor receptor inhibitors and combinations in non-small cell lung cancer patients.

Role of maspin in cancer.

Maspin (mammary serine protease inhibitor), is a member of the serine protease inhibitor/non-inhibitor superfamily. Its expression is down-regulated in breast, prostate, gastric and melanoma cancers but over-expressed in pancreatic, gallbladder, colorectal, and thyroid cancers suggesting that maspin may play different activities in different cell types. However, maspin expression seems to be correlated with better prognosis in prostate, bladder, lung, gastric, colorectal, head and neck, thyroid and melanoma cancer. In breast and ovarian cancer maspin significance is associated with its subcellular localization: nucleus maspin expression correlates with a good prognosis, whilst in pancreatic cancer it predicts a poor prognosis. Since tumor metastasis requires the detachment and invasion of tumor cells through the basement membrane and stroma, a selectively increased adhesion by the presence of maspin may contribute to the inhibition of tumor metastasis. Furthermore the different position of maspin inside the cell or its epigenetic modifications may explain the different behavior of the expression of maspin between tumors. The expression of maspin might be useful as a prognostic and possibly predictive factor for patients with particular types of cancer and data can guide physicians in selecting therapy. Its expression in circulating tumor cells especially in breast cancer, could be also useful in clinical practice along with other factors, such as age, comorbidities, blood examinations in order to select the best therapy to be carried out. Focusing on the malignancies in which maspin showed a positive prognostic value, therapeutic approaches studied so far aimed to re-activate a dormant tumor suppressor gene by designed transcription factors, to hit the system that inhibits the expression of maspin, to identify natural substances that can determine the activation and the expression of maspin or possible "molecules binds" to introduce maspin in cancer cell and gene therapy capable of up-regulating the maspin in an attempt to reduce primarily the risk of metastasis.Further studies in these directions are necessary to better define the therapeutic implication of maspin.
