Chemotherapy-induced nausea and vomiting (CINV) in patients with advanced lung cancer during the first-line treatment: assessment by physicians, nurses, and patients from an Italian multicenter survey.

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) still represents a common side-effect of chemotherapy, and often, its perception differs between patients and healthcare professionals. The aim of this study was to evaluate the agreement on the perception of CINV and other items among clinicians, patients, and nurses. METHODS: This observational prospective study was part of an evaluation program promoted by the Women Against Lung Cancer in Europe (WALCE) Onlus. From August 2015 to February 2016, a survey was administered in 11 oncologic institutions to 188 stage IV lung cancer patients and to their oncologists and nurses during first-line chemotherapy. Our survey investigated 11 aspects: anxiety, mood, weakness, appetite, nausea, vomiting, pain, drowsiness, breath, general condition, and trust in treatments. These items were assessed through Numerical Rating Scale at four consecutive evaluations: at T0 (immediately prior to the first cycle), at T1 (immediately prior to the second cycle), at T2 (immediately prior to the third cycle), and at T3 (immediately prior to the fourth cycle). Clinician versus patient (CvP), nurse versus patient (NvP), and clinician versus nurse (CvN) agreements were estimated applying Weighted Cohen's kappa. A multivariate logistic model and generalized equation estimates were applied to evaluate factors possibly influencing CINV development. RESULTS: The incidence of patients reporting CINV varied from 40% at T0 to 71% at T3. Both CvP and NvP agreement on the investigated items were mainly moderate, slightly increasing over time, and becoming substantial for some items, in particular for NvP. Pre-chemotherapy anxiety in its mild, moderate, and severe manifestations, as well as mild, moderate, and severe anxiety experienced after chemotherapy start, exposed patients to a higher risk of anticipatory and acute/delayed CINV, respectively. CONCLUSIONS: Despite clinical staff awareness of patients' status and perceptions, CINV still represents a clinical problem. This study confirms that particular attention should be paid to anxiety due to its key role in CINV development.

KRAS G12C mutation and risk of disease recurrence in stage I surgically resected lung adenocarcinoma.

KRAS G12C mutations are found in about 12-13% of LUAD samples and it is unclear whether they are associated with worse survival outcomes in resected, stage I LUAD. We assessed whether KRAS-G12C mutated tumours had worse DFS when compared to KRAS-nonG12C mutated tumours and to KRAS wild-type tumours in a cohort of resected, stage I LUAD (IRE cohort). We then leveraged on publicly available datasets (TCGA-LUAD, MSK-LUAD604) to further test the hypothesis in external cohorts. In the stage I IRE cohort we found a significant association between the KRAS-G12C mutation and worse DFS in multivariable analysis (HR: 2.47). In the TCGA-LUAD stage I cohort we did not find statistically significant associations between the KRAS-G12C mutation and DFS. In the MSK-LUAD604 stage I cohort we found that KRAS-G12C mutated tumours had worse RFS when compared to KRAS-nonG12C mutated tumours in univariable analysis (HR 3.5). In the pooled stage I cohort we found that KRAS-G12C mutated tumours had worse DFS when compared to KRAS-nonG12C mutated tumours (HR 2.6), to KRAS wild-type tumours (HR 1.6) and to any other tumours (HR 1.8); in multivariable analysis, the KRAS-G12C mutation was associated with worse DFS (HR 1.61). Our results suggest that patients with resected, stage I LUAD with a KRAS-G12C mutation may have inferior survival outcomes..

Social distress among medical oncologists and other healthcare professionals during the first wave of COVID-19 pandemic in Italy.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has rapidly spread to every country around the world taking on pandemic proportions. Since 8 March 2020, the Italian government ordered a nationwide lockdown with unavoidable social isolation. Healthcare professionals (HCPs) represent the most physically and emotionally involved category. The aim of this study is to assess the social distress among HCPs in Italy. PATIENTS AND METHODS: In this online, totally anonymous survey, 24 multiple choice questions were posed to medical staff employed in the Italian Healthcare System during the COVID-19 pandemic. Data collection was performed from 30 March to 24 April 2020. RESULTS: A total of 600 HCPs completed the questionnaire. The majority of respondents expressed the fear of being at higher risk of contagion than the general population (83.3%) and the weighty concern of infecting their families (72.5%). An insufficient supply of personal protective equipment (PPE; P = 0.0003) and inadequate training about procedures to follow (P = 0.0092) were seen to significantly coincide with these worries. More than two-thirds declared a change in family organisation, which showed a significant correlation with the concern of infecting their relatives (P < 0.0001). CONCLUSIONS: This is the first Italian survey on social distress among HCPs during the COVID-19 pandemic. The unavailability of PPE, screening procedures and adequate training strongly affected HCPs' emotional status. Although there was a predominance of oncologists (especially from the North of Italy), which impairs the generalisation of our findings, this survey underlined the social impact that this health emergency has had on HCPs.

Single-arm, open label prospective trial to assess prediction of the role of ERCC1/XPF complex in the response of advanced NSCLC patients to platinum-based chemotherapy.

BACKGROUND: Platinum-based therapy, combined or not with immune checkpoint inhibitors, represents a front-line choice for patients with non-small-cell lung cancer (NSCLC). Despite the improved outcomes in the last years for this malignancy, only a sub-group of patients have long-term benefit. Excision repair cross-complementation group 1 (ERCC1) has been considered a potential biomarker to predict the outcome of platinum-based chemotherapy in NSCLC. However, the ERCC1 gene is transcribed in four splice variants where the isoform 202 was described as the only one active and able to complex Xeroderma pigmentosum group F-complementing protein (XPF). Here, we prospectively investigated if the active form of ERCC1, as assessed by the ERCC1/XPF complex (ERCC1/XPF), could predict the sensitivity to platinum compounds. PATIENTS AND METHODS: Prospectively enrolled, patients with advanced NSCLC treated with a first-line regimen containing platinum were centrally evaluated for ERCC1/XPF by a proximity ligation assay. Overall survival (OS), progression-free survival (PFS) and objective response rate (ORR) were analyzed. RESULTS: The absence of the ERCC1/XPF in the tumor suggested a trend of worst outcomes in terms of both OS [hazard ratio (HR) 1.41, 95% confidence interval (CI) 0.67-2.94, P = 0.373] and PFS (HR 1.61, 95% CI 0.88-3.03, P = 0.123). ORR was marginally influenced in ERCC1/XPF-negative and -positive groups [odds ratio (stable disease + progressive disease versus complete response + partial response) 0.87, 95% CI 0.25-3.07, P = 0.832]. CONCLUSION: The lack of ERCC1/XPF complex in NSCLC tumor cells might delineate a group of patients with poor outcomes when treated with platinum compounds. ERCC1/XPF absence might well identify patients for whom a different therapeutic approach could be necessary.

Nuclear and cytoplasmic cellular distribution of survivin as survival predictor in resected non-small-cell lung cancer.

AIM: Survivin is a member of the inhibitors of apoptosis (IAP) gene family that acts through pathways different from those involving the bcl-2 family. Largely undetectable in normal adult tissues, survivin is deregulated in most human cancers including non-small-cell lung cancer (NSCLC) and may represent a tumor marker with prognostic and therapeutic implications. Aim of our study was to determine the prognostic role of survivin as an apoptosis-related biomarker in a series of resected NSCLC patients. METHODS: A retrospective series of resected NSCLC patients were retrieved from the files of the Regina Elena National Cancer Institute. Survivin was detected by immunohistochemistry (IHC) using a polyclonal antibody. Survivin displayed two kinds of immunoreactivity: (i) a diffuse cytoplasmic staining and (ii) a distinct nuclear staining. A score-scale to distinguish positive (score 1-2) vs. negative (score 0) pattern was applied. Clinical and biological (nuclear and cytoplasmic survivin staining) covariables were screened for a prognostic relationship with overall survival (OS) and disease-free survival (DFS) into the univariate and multivariate analyses. RESULTS: Data referring to 116 NSCLC patients who underwent surgery for stage I-IIIA NSCLC were collected. Multivariate analyses identified tumor size, nodal status and nuclear, but not cytoplasmic, expression of survivin as significant independent predictors of OS, with a hazard ratio of 2.40 (95% CI 1.44, 3.99, p=0.001), 2.03 (95% CI 1.26, 3.26, p=0.003) and 1.83 (95% CI 1.01, 3.30, p=0.044), respectively. Median OS for nuclear survivin positive (score 1-2) and negative (score 0) patients were 23 months (95% CI 15, 31) and 36 months (95% CI 1, 76), respectively (p=0.01); five-year survival for score 1-2 and score 0 patients were 20% and 44.5%, respectively. Conversely, no significant impact on survival is found when patients are stratified according to cytoplasmic survivin expression. CONCLUSIONS: Data presented herein open the issue that prognosis of stage I-IIIA NSCLC can be linked to the cellular pattern of distribution of survivin.

Gene expression of ERCC1 as a novel prognostic marker in advanced bladder cancer patients receiving cisplatin-based chemotherapy.

BACKGROUND: Customizing chemotherapy on the basis of chemosentitivity prediction may improve outcome in advanced bladder cancer patients. Since DNA damaging agents are the cornerstones of therapy, we hypothesized that levels of DNA repair genes could predict survival. PATIENTS AND METHODS: Messenger RNA expression levels of excision repair cross complementing 1 (ERCC1), breast cancer 1 (BRCA1), ribonucleotide reductase subunit M1 (RRM1) and caveolin-1 were determined by RT-PCR in tumor DNA from 57 advanced and metastatic bladder cancer patients treated with either gemcitabine/cisplatin or gemcitabine/cisplatin/paclitaxel (Taxol). Levels were correlated with survival, time to disease progression and chemotherapy response. RESULTS: Median survival was significantly higher in patients with low ERCC1 levels (25.4 versus 15.4 months; P = 0.03) (median follow-up 19 months). A trend towards longer time to progression was observed in patients with tumors expressing low levels of all markers. Levels of RRM1, BRCA1 and caveolin-1, however, failed to predict the survival and a clear link with chemotherapy response could not be established. On multivariate analysis with pretreatment prognostic factors, ERCC1 emerged as an independent predictive factor for survival. CONCLUSION: The results of the study indicate that ERCC1 may predict survival in bladder cancer treated by platinum-based therapy.

Second- and third-generation aromatase inhibitors as first-line endocrine therapy in postmenopausal metastatic breast cancer patients: a pooled analysis of the randomised trials.

The purpose of this study was to estimate in all randomised trials the relative risk of overall response rate (ORR), clinical benefit (CB), time to progression (TTP), overall survival (OS), and toxicity of aromatase inhibitors (AI), compared with tamoxifen (Tam) as first-line endocrine therapy in postmenopausal metastatic breast cancer (PMBC) women. Prospective randomised studies were searched through computerised queries of MEDLINE, EMBASE, and the American Society of Clinical Oncology (ASCO) abstract database. Relative risk, 95% confidence interval, and heterogeneity were derived according to the inverse variance and Mantel-Haenszel method and Q statistics. Six phase III prospective randomised trials including 2787 women were gathered. A significant advantage in ORR (P = 0.042), TTP (P = 0.007), and CB (P = 0.001) in favour of AI over Tam was detected at the fixed effects model. These results were not significant at the random effects model, owing to the significant heterogeneity. On the contrary, no difference was registered for OS (P = 0.743) with no significant heterogeneity. Regarding toxicity, Tam caused more frequently thromboembolic events (P = 0.005) and vaginal bleeding (P = 0.001) compared with AI. Aromatase inhibitors appear to be superior to Tam as first-line endocrine option in PMBC women. Owing to a component of variability between the six studies analysed, the random effects estimates differed from corresponding fixed ones. Investigators should assess heterogeneity of trial results before deriving summary estimates of treatment effect.
