RESUMO
BACKGROUND: Tumor spread through air spaces (STAS) in lung adenocarcinoma is a novel mechanism of invasion. STAS has been proposed as an independent predictor of poor prognosis. The aim of this study was to evaluate the correlations between STAS status and other clinicopathologic variables and to assess the prognostic implications of STAS and the distance from the edge of the tumor to the farthest STAS in patients with resected lung adenocarcinoma. MATERIAL AND METHODS: This is a single-institution retrospective observational study. We included all patients with resected lung adenocarcinoma from January 2017 to December 2018 at La Paz University Hospital. The cut-off for the distance from the edge of the tumor to the farthest STAS was 1.5 mm and was assessed by the area under the receiver operating characteristic curve. RESULTS: A total of 73 patients were included. STAS was found in 52 patients (71.2%). Histological grade 3 (P = 0.035) and absence of lepidic pattern (P = 0.022) were independently associated with the presence of STAS. The median recurrence-free survival (RFS) was 48.06 months [95% confidence interval (CI) 33.58 months to not reached]. STAS-positive patients had shorter median RFS [39.23 months (95% CI 29.34-49.12 months)] than STAS-negative patients (not reached) (P = 0.04). STAS-positive patients with a distance from the edge of the tumor to the farthest STAS ≥1.5 mm had an even shorter median RFS [37.63 months (95% CI 28.14-47.11 months)]. For every 1 mm increase in distance, the risk of mortality increased by 1.26 times (P = 0.04). CONCLUSIONS: Histological grade 3 and absence of lepidic pattern were independently associated with the presence of STAS. STAS was associated with a higher risk of recurrence. The distance from the edge of the tumor to the farthest STAS also had an impact on overall survival.

BACKGROUND: Malignant pleural mesothelioma (MPM) is a rare and aggressive tumor, with a poor prognosis. MPM needs to find prognostic factors of survival. We provided the management of patients with MPM and sought to determine whether pre-treatment levels of derived neutrophil-to-lymphocyte ratio (dNLR) as well as PD-L1 expression were reliable prognostic factors of survival. METHODS: We conducted a single-institution retrospective study, including all patients with MPM treated at La Paz University Hospital between December 2009 and March 2018. Baseline disease, demographics, clinical data, treatment characteristics and complete blood cell counts were collected. We examined dNLR at baseline and data for PD-L1 expression were analyzed in tumor cells by immunohistochemistry. RESULTS: We included 25 patients. The median overall survival (OS) was 15.7 months (95% CI 11.3-20.0). 5 patients had a dNLR greater than 3 (20%). Patients with a dNLR greater than 3 had shorter median OS (8.5 months), than patients with a dNLR less than 3 (17.0 months), with statistically significant differences (p = 0.038). Ten patients (40%) had positive PD-L1 expression (≥ 1%). Patients with positive PD-L1 expression had shorter median OS (8.5 months) than patients with negative PDL1 expression (15.7 months), but without statistically significant association (p = 0.319). CONCLUSION: The survival data obtained in our sample are consistent with those previously reported. Pretreatment levels of dNLR greater than 3 and positive PD-L1 expression could be significant prognostic factors for poor survival in patients with MPM. Further and prospective studies are needed to explore this relationship and to derive definitive conclusions.

Lung cancer in young patients is an uncommon and understudied entity that harbors distinctive epidemiological, clinic-demographic, and genomic features. We carried out a systematic review of genomic profiling in young patients with lung cancer from 2010 to 2020 in the main electronic databases and selected 23 manuscripts. Lung cancer in young patients occurs more frequently in women with adenocarcinoma histology and at more advanced stages. Some studies report higher oncogenic genomic alteration in this population, with higher anaplastic lymphoma kinase rearrangements, a distinct profile of epidermal growth factor receptor mutations, and other novel genomic alterations. Although still uncommon, the implementation of next-generation sequencing (NGS) has shed some light on germline genomic alterations associated with lung cancer in young patients. Although outcomes when compared with the older population are conflicting, the overall prognosis is still poor in this subset of patients and efforts to find targetable genomic alterations should be made to improve survival.

BACKGROUND: Cancer and cancer therapies have been associated with an increased incidence of venous thromboembolic events (VTE). However, the incidence of VTE in patients on immunotherapy has not been well characterized. The aim of this study was to assess the incidence of VTE in cancer patients receiving immunotherapy and ascertain its prognostic utility. MATERIALS AND METHODS: We conducted a single-institution retrospective study, including all cancer patients treated with anti-Programmed cell Death 1 (PD-1), anti-Programmed cell Death Ligand-1 (PD-L1), anti-Cytotoxic T-Lymphocyte-Associated Protein 4 (CTLA4), a combination of anti-PD-1/anti-PD-L1 and anti-CTLA4 or a combination including any of these drugs with chemotherapy, antiangiogenic agents or both between June 2013 and April 2019 at La Paz University Hospital, Madrid (Spain). RESULTS: We selected 229 patients. VTE occurred in 16 of 229 patients (7%). VTE occurred more frequently in patients with lung cancer followed by melanoma. Female sex and melanoma were independently associated with an increased risk of VTE. 12 of 16 VTE (75%) were symptomatic. Progressive disease to immunotherapy [HR 31.60 (95% CI 11.44-87.22), p = 0.00], lung cancer [HR 2.55 (95% CI 1.34-4.86), p = 0.00] and melanoma [HR 2.42 (1.20-4.86), p = 0.01] were independently associated with shorter OS. VTE occurrence was not independently associated with shorter OS [HR 1.33 (95% CI 0.63-2.80), p = 0.44]. CONCLUSIONS: The incidence of VTE in cancer patients receiving immunotherapy in our study appeared to be similar to the incidence previously reported in other series of cancer patients treated with systemic therapies. VTE occurrence did not correlate with the prognosis. Further and prospective studies are needed to derive definitive conclusions.

BACKGROUND: The prognostic value of neutrophil-to-lymphocyte ratio (NLR) has been extensively studied in cancer patients. However, the performance of NLR as an early marker of efficacy of immune checkpoint inhibitors (ICI) is still understudied. We studied the utility of NLR at baseline (bNLR), before the second dose of immunotherapy (NLR2) and the NLR trend for predicting efficacy outcomes. METHODS: We included all patients with advanced cancer treated with ICI from June 2013 to April 2019 at La Paz University Hospital, Madrid (Spain). We examined bNLR, NLR2 and NLR trend and explored the association with progression-free survival (PFS) at 6 months, median PFS and overall survival (OS). RESULTS: We included 211 patients. PFS and OS were significantly longer in the low bNLR group than in the high bNLR group [HR 0.71 (95% CI 0.60-0.84) and HR: 0.66 (95% CI 0.55-0.79), respectively]. Regarding NLR2, patients with low NLR2 had significantly longer PFS and OS than patients with high NLR2 [HR 0.67 (95% CI 0.57-0.79) and HR: 0.60 (95% CI 0.50-0.72), respectively]. Finally, for NLR trend, PFS and OS for patients with NLR trend < 1 were significantly longer than those patients with NLR trend ≥ 1 [HR 0.59 (95% CI 0.43-0.82) and HR 0.63 (95% CI 0.44-0.90), respectively]. At the multivariate analysis for PFS and OS, bNLR, NLR2 and NLR trend were all independent prognostic factors for PFS and OS. CONCLUSIONS: bNLR, NLR2 and NLR trends are independent prognostic factors for survival in patients on immunotherapy. The dynamics of NLR in patients on immunotherapy is a promising marker that needs further investigation.

INTRODUCTION: Depression in cancer patients is prevalent and negatively impacts their quality of life. Likewise, it correlates with lower overall survival. The aim of this work is to analyze whether different coping strategies, as well as sociodemographic and clinical factors are associated with the presence of depressive symptoms in individuals with a resected, non-metastatic neoplasm about to initiate adjuvant chemotherapy. METHODS: NEOcoping is a cross-sectional, prospective, observational, multicenter study. Clinical (tumor site and stage, time to diagnosis, risk of recurrence, and type of adjuvant treatment) and sociodemographic characteristics (age, gender, marital status, educational level, occupational sector, and employment status), coping strategies (Mini-MAC scale), and depressive symptoms (BSI scale) were collected. A two-block linear regression model was performed to determine the predictive variables of depressive symptoms. RESULTS: 524 adults with resected, non-metastatic cancer were recruited. Twenty-six percent of patients have clinically significant depressive symptoms. Being female, < 40 years of age, having breast and stomach cancer, and > 50% chance of recurrence were associated with increased risk of depression. Likewise, depression was associated with greater helplessness and anxious preoccupation, and less fighting spirit. Age, gender, and risk of recurrence accounted for only 7% of the variance in depressive symptoms. Including coping strategies in the regression analysis significantly increased the variance explained (48.5%). CONCLUSION: Early psychological intervention in patients with maladaptive coping strategies may modulate the onset of depressive symptoms, especially in those at higher risk for depression.

BACKGROUND: Capectiabine is an oral antineoplastic drug used in multiple malignancies. Proton pump inhibitors (PPI) have been proven to interact with other oral antineoplastic agents. In this systematic review we will summarize the clinical evidence on the efficacy of capecitabine when used concomitantly with PPI. MATERIALS AND METHODS: We performed a systematic literature search on the main databases up to November 2019. RESULTS: Nine studies met our inclusion criteria: 8 retrospective studies and 1 phase II clinical trial. Patients with colorectal, breast and gastroesophageal were represented. Four out of the 9 studies reported a shorter efficacy outcome in uni- or multivariate analysis when capecitabine was taken concomitantly with PPI than alone. CONCLUSIONS: Up to date, the clinical evidence reported on the use of capecitabine concomitantly with PPI is scarce and shows conflicting results. While awaiting further data, avoiding misuse of PPI in cancer patients taking capecitabine is recommended.

INTRODUCTION: This study analyzes the prevalence of malnutrition, depression, anxiety, and somatization and which factor has the biggest effect on quality of life (QoL) in individuals with resected cancer. METHODS: A prospective study was conducted among 747 participants. Participants completed the EORTC-QLQ30, MST, and BSI-18 questionnaires. RESULTS: Prevalence for risk of malnutrition, depression, anxiety, and somatization were 36.4%, 35.5%, 35.2%, and 48.8%, respectively. Hierarchical multiple regression analyses revealed that malnutrition risk, somatization, depression, and anxiety accounted for 50.8% of the variance in functional scale, 45.3% in symptom scale, and 52.2% in global health. Malnutrition, somatization, depression, and anxiety displayed high explanatory power on all health-related QoL (HRQoL) scales. CONCLUSION: The risk of malnutrition and psychological symptoms is strongly associated with HRQoL in cancer patients; thus, medical oncologists should develop effective interventions that contribute to lowering the risk of malnutrition and psychological distress, thereby improving subjects' HRQoL before initiating adjuvant chemotherapy.

OBJECTIVE: The aim of this study was to analyze the psychometric properties of the Shared Decision-Making Questionnaire-Physician version (SDM-Q-Doc) in a sample of medical oncologists who provide adjuvant treatment to patients with non-metastatic resected cancer and the correlations between the total SDM-Q-Doc score and physician satisfaction with the information provided. METHODS: Prospective, observational and multicenter study in which 32 medical oncologists and 520 patients were recruited. The psychometric properties, dimensionality, and factor structure of the SDM-Q-Doc were assessed. RESULTS: Exploratory factor analyses suggested that the most likely solution was two-dimensional, with two correlated factors: one factor regarding information and another one about treatment. Confirmatory factor analysis based on cross-validation showed that the fitted two-dimensional solution provided the best fit to the data. Reliability analyses revealed good accuracy for the derived scores, both total and sub-scale, with estimates ranging from 0.81 to 0.89. The results revealed significant correlations between the total SDM-Q-Doc score and physician satisfaction with the information provided (p < 0.01); between information sub-scale scores (factor 1) and satisfaction (p < 0.01), and between treatment sub-scale scores (factor 2) and satisfaction (p < 0.01). Medical oncologists of older age and those with more years of experience showed more interest in the patient preferences (p = 0.026 and p = 0.020, respectively). Patient age negatively correlated with SDM information (p < 0.01) and physicians appear to provide more information to young patients. CONCLUSION: SDM-Q-Doc showed good psychometric properties and could be a helpful tool that examines physician's perspective of SDM and as an indicator of quality and satisfaction in patients with cancer.

BACKGROUND: Oxaliplatin-based chemotherapy (CT), widely used as adjuvant therapy for stage III and selected high-risk stage II colon cancer (CC) patients, is often associated with cumulative peripheral neuropathy. Our aim is to identify single-nucleotide polymorphisms (SNPs) in genes involved in oxaliplatin metabolism, DNA repair mechanisms, cell cycle control, detoxification or excretion pathways to predict severe (grade 2-3) oxaliplatin-induced peripheral neuropathy (OXPN) among CC patients treated with oxaliplatin and fluoropyrimidine-based adjuvant CT. PATIENTS AND METHODS: Genomic DNA was extracted from formalin-fixed-paraffin-embedded peritumoral samples from 206 high-risk stage II and stage III CC patients receiving oxaliplatin-based adjuvant CT from January 2004 to December 2009. Genotyping was carried out for 34 SNPs in 15 genes using MassARRAY (SEQUENOM) technology. A total of 181 stage II-III CC patients treated with the same CT regimens were enrolled as a validation set. RESULTS: The rs2230641 cyclin H (CCNH) rs2230641 C/C [odd ratio (OR)=5.03, 95% confidence interval (CI) 1.061-2.41, P=0.042] and the ATP-binding cassette subfamily G, member 2 (ABCG2) rs3114018 A/A genotypes (OR=2.67; 95% CI 0.95-4.41; P=0.059) were associated with a higher risk of severe OXPN. In addition, patients harboring the combination of CCNH C/C and/or the ABCG2 rs3114018 A/A genotypes had a higher risk of grade 2-3 OXPN than those with the CCNH any T and ABCG2 any C genotypes (37.73% versus 19.42%; OR=2.46; 95% CI 1.19-5.07; P=0.014) in the logistic regression analysis using age, gender, adjuvant CT regimen and cumulative dose of oxaliplatin as covariates. The ability to predict severe OXPN of this combined analysis was independently validated in the second cohort (58% versus 33.33%; OR=2.99; 95% CI 1.45-6.13; P=0.002). CONCLUSIONS: Our results suggest that SNPs in CCNH and ABCG2 can modulate the development of severe OXPN among stage II-III CC patients who received oxaliplatin-based CT, thus enabling the individualization of adjuvant treatment.
