Gender influence on work satisfaction and leadership for medical oncologists: a survey of the Spanish Society of Medical Oncology (SEOM).

BACKGROUND: Women represent an increasing proportion of the oncology workforce; however, globally this does not translate into leadership roles, reflecting disparities in career opportunities between men and women. The Spanish Society of Medical Oncology (SEOM) undertook a survey to investigate gender disparity in the Spanish oncology context. DESIGN: An online survey was made available to SEOM medical oncologists between February and May 2019. It included demographics, professional context and achievements, parenthood and family conciliation issues, workplace gender bias, and approaches to address disparities. RESULTS: Of the 316 eligible respondents, 71.5% were women, 59.5% were aged 45 or younger, and 66.1% had children. Among women, 12.4% were division or unit heads, compared with 45.5% of men, with most women (74.3%) being attending medical oncologists, compared with 45.5% of men. More males were professors (34.4% versus 14.2% of females), had a PhD (46.7% versus 28.8%), and/or had led clinical research groups (41.1% versus 9.7%). Spending time overseas after completing a residency was also more common for men than women (34.4% versus 20.4%). Professional satisfaction was similar between genders, driven primarily by patient care and intellectual stimulation. More women (40.7%) considered parenthood to have a strong negative impact on their career, compared with men (9.0%). Main perceived barriers to gender equality included a lack of work-life balance (72.6% women, 44.4% men), bias of peers and superiors (50.0% women, 18.9% men), and different career goals (41.2% women, 24.4% men). Preferred solutions included educational programs and scholarships (52.9%), communication and leadership training (35.8%), childcare at conferences (33.2%), and postmaternity return-to-work incentives (32.0%). CONCLUSION: There is a clear paucity of equal opportunities for female oncologists in Spain. This can be addressed by encouraging professional development and merit recognition particularly for younger female oncologists, and empowering women to be involved in management and leadership of institutions and professional societies.

Treatment strategy optimization for patients with non-small-cell lung cancer harboring EGFR mutation: a Delphi consensus.

AIM: To stablish a consensus on the treatment strategy for advanced non-small-cell lung cancer (aNSCLC) with epidermal growth factor receptor mutation (EGFRm) in Spain. METHODS: After a systematic literature review, the scientific committee developed 33 statements in 4 fields: molecular diagnosis (10 items); histologic profile and patient clinical characteristics (7 items); first-line (1L) treatment in EGFRm aNSCLC (8 items); and subsequent-line treatment (8 items). A panel of 31 experts completed 2 Delphi online questionnaires rating their degree of agreement/disagreement for each statement through a 1-9 range scale (1-3 = disagree, 7-9 = agree). Consensus was reached if 2/3 of the participants are in the median range. RESULTS: In the first Delphi round consensus was achieved for 24/33 of the statements. One of the assertions was deleted, proceeding to a second round with the eight remaining questions with no consensus or in the range of indeterminacy. Determination of the EGFR status from tissue and analysis of the different biomarkers are two important variables that influenced treatment decision in patients with aNSCLC. 1L treatment should be the best therapeutic option, independently of the subsequent lines of treatment. For patients with the most common activating mutations osimertinib was considered the most efficient and safe 1L option. In case of disease progression, a new biopsy was needed. CONCLUSIONS: A consensus document is proposed to optimize the treatment strategy for untreated patients with a NSCLC with EGFR sensitizing mutations.

SEOM clinical guidelines for the treatment of small-cell lung cancer (SCLC) (2019).

Small-cell lung cancer (SCLC) accounts for 15% of lung cancers. Only one-third of patients are diagnosed at limited stage. The median survival remains to be around 15-20 months without significative changes in the strategies of treatment for many years. In stage I and IIA, the standard treatment is the surgery followed by adjuvant therapy with platinum-etoposide. In stage IIB-IIIC, the recommended treatment is early concurrent chemotherapy with platinum-etoposide plus thoracic radiotherapy followed by prophylactic cranial irradiation in patients without progression. However, in the extensive stage, significant advances have been observed adding immunotherapy to platinum-etoposide chemotherapy to obtain a significant increase in overall survival, constituting the new recommended standard of care. In the second-line treatment, topotecan remains as the standard treatment. Reinduction with platinum-etoposide is the recommended regimen in patients with sensitive relapse (≥ 3 months) and new drugs such as lurbinectedin and immunotherapy are new treatment options. New biomarkers and new clinical trials designed according to the new classification of SCLC subtypes defined by distinct gene expression profiles are necessary.

Updated guidelines for predictive biomarker testing in advanced non-small-cell lung cancer: a National Consensus of the Spanish Society of Pathology and the Spanish Society of Medical Oncology.

In 2011 the Spanish Society of Medical Oncology (SEOM) and the Spanish Society of Pathology (SEAP) started a joint project to establish guidelines on biomarker testing in patients with advanced non-small-cell lung cancer (NSCLC) based on current evidence. As this field is constantly evolving, these guidelines have been updated, previously in 2012 and 2015 and now in 2019. Current evidence suggests that the mandatory tests to conduct in all patients with advanced NSCLC are for EGFR and BRAF mutations, ALK and ROS1 rearrangements and PD-L1 expression. The growing need to study other emerging biomarkers has promoted the routine use of massive sequencing (next-generation sequencing, NGS). The coordination of every professional involved and the prioritisation of the most suitable tests and technologies for each case remains a challenge.

Treatment options beyond immunotherapy in patients with wild-type lung adenocarcinoma: a Delphi consensus.

PURPOSE: Immunotherapy-based approaches are standard first-line treatments for advanced/metastatic lung cancer or for chemoradiotherapy consolidation in locally advanced disease. Uncertainty on how to treat patients at disease progression prompted us to develop a consensus document on post-immunotherapy options in Spain for patients with advanced wild-type lung adenocarcinoma. METHODS: After extensive literature review, a 5-member scientific committee generated 33 statements in 4 domains: general aspects (n = 4); post-durvalumab in locally advanced disease (n = 6); post-first-line immunotherapy ± chemotherapy in advanced/metastatic disease (n = 11); and post-first-line platinum-based chemotherapy in advanced/metastatic disease (n = 12). A panel of 26 lung cancer experts completed 2 Delphi iterations through an online platform rating their degree of agreement/disagreement (first-round scale 1-5 and second-round scale 1-4, 1 = strongly disagree, 4/5 = strongly agree) for each statement. Second-round consensus: ≥ 70% of responses were in categories 1/2 (disagreement) or 3/4 (agreement). RESULTS: Consensus was reached for 2/33 statements in the first Delphi round and in 29/31 statements in the second round. Important variables informing treatment at disease progression with an immunotherapy-based treatment include: disease aggressiveness, previous treatment, accumulated toxicity, progression-free interval, PD-L1 expression, and tumour mutational burden. A platinum-based chemotherapy should follow a first-line immunotherapy treatment without chemotherapy. Treatment with docetaxel + nintedanib may be appropriate post-durvalumab in refractory patients or following progression to first-line chemotherapy + immunotherapy, or second-line chemotherapy after first-line immunotherapy, or first-line chemotherapy in some patients with low/negative PD-L1 expression, or second-line immunotherapy after first-line chemotherapy. CONCLUSIONS: To support decision making following progression to immunotherapy-based treatment in patients with advanced wild-type lung adenocarcinoma, a consensus document has been developed.

Clinical utility of plasma-based digital next-generation sequencing in patients with advance-stage lung adenocarcinomas with insufficient tumor samples for tissue genotyping.

BACKGROUND: Approximately 30% of tumor biopsies from patients with advanced-stage lung adenocarcinomas yield insufficient tissue for successful molecular subtyping. We have analyzed the clinical utility of next-generation sequencing (NGS) of cell-free circulating tumor DNA (ctDNA) in patients with inadequate tumor samples for tissue genotyping. PATIENTS AND METHODS: We conducted the study in a multi-institutional prospective cohort of clinically unselected patients with advanced-stage lung adenocarcinomas with insufficient tissue for EGFR, ALK or ROS1 genotyping across 12 Spanish institutions (n = 93). ctDNA NGS was carried out by Guardant Health (Guardant360, Redwood City, CA), using a hybrid-capture-based 73-gene panel. Variants were deemed actionable if they were part of the OncoKB precision oncology knowledge database and classified in four levels of actionability based on their clinical or preclinical evidence for drug response. RESULTS: Eighty-three out of 93 patients (89%) had detectable levels of ctDNA. Potentially actionable level 1-4 genomic alterations were detected in 53 cases (57%), of which 13 (14%) had level 1-2A alterations (Food and Drug Administration-approved and standard-care biomarkers according to lung cancer guidelines). Frequencies of each genomic alteration in ctDNA were consistent with those observed in unselected pulmonary adenocarcinomas. The majority of the patients (62%), particularly those with actionable alterations (87%), had more than one pathogenic variant in ctDNA. The median turnaround time to genomic results was 13 days. Twelve patients (13%) received genotype-matched therapies based on ctDNA results, deriving the expected clinical benefit. Patients with co-occurring pathogenic alterations had a significantly shorter median overall survival as compared with patients without co-occurring pathogenic alteration (multivariate hazard ratio = 5.35, P = 0.01). CONCLUSION: Digital NGS of ctDNA in lung cancers with insufficient tumor samples for tissue sequencing detects actionable variants that frequently co-occur with other potentially clinically relevant genomic alterations, allowing timely initiation of genotype-matched therapies.

Efficacy of tyrosine kinase inhibitors in EGFR-mutant lung cancer women in a real-world setting: the WORLD07 database.

BACKGROUND: The WORLD07 project is a female specific database to assess the characteristics of women with lung cancer. METHODS: WORLD07 database sets up in 2007, and prospectively stores clinical characteristics, treatment, outcome, and follow-up of lung cancer women. All women with epidermal growth factor receptor (EGFR) mutation non-small cell lung cancer (NSCLC) were selected for this analysis. RESULTS: From October 2007 to December 2012, a total of 1775 NSCLC women were recruited. EGFR mutation was identified in 34.4% of patients. Upfront EGFR tyrosine kinase inhibitor (TKI) reported a response rate of 60%, a median progression-free survival of 11.7 months, and median overall survival of 23.0 months. EGFR TKI, EGFR-mutation type, and smoking status did not impact in the outcome of treated women. CONCLUSION: Prevalence of EGFR mutation in women with NSCLC is higher than overall population with NSCLC. Efficacy of EGFR TKI in this real-world setting is similar to that previously reported.

Long-term survival in advanced non-squamous NSCLC patients treated with first-line bevacizumab-based therapy.

BACKGROUND/AIM: First-line bevacizumab-based therapies have been shown to improve clinical outcomes in patients with non-squamous non-small-cell lung cancer (NSCLC). We aimed to descriptively analyse patients with non-squamous NSCLC who received a long-term period of maintenance bevacizumab. PATIENTS AND METHODS: This retrospective study included 104 patients who had already reached a progression-free survival (PFS) of at least 9 months. RESULTS: Median overall survival and PFS were 30.7 and 15.1 months, respectively. The overall response rate was 83 %. Weight loss ≤5 %, ECOG PS = 0, or low number of metastatic sites seem to be predictive factors of good evolution. The incidence of bevacizumab-related adverse events appeared to be similar as the previous studies. CONCLUSION: Our findings show that there is a long-term survivor group whom the administration of bevacizumab resulted in a relevant prolongation of response without new safety signals. Due to the population heterogeneity, it was not possible to identify the standardised predictive factors.

A consensus statement on the gender perspective in lung cancer.

Lung cancer is the most common cancer globally and has the highest mortality. Although this disease is not associated with a particular gender, its incidence is rising among women, who are diagnosed at an increasingly younger age compared with men. One of the main reasons for this rise is women taking up smoking. However, many non-smoking women also develop this disease. Other risk factors implicated in the differential development of lung cancer in women are genetic predisposition, tumour histology and molecular profile. Proportionally more women than men with lung cancer have a mutation in the EGFR gene. This consensus statement reviews the available evidence about the epidemiological, biological, diagnostic, therapeutic, social and psychological aspects of lung cancer in women.

SEOM Clinical Guideline for bone metastases from solid tumours (2016).

Bone metastases are common in many advanced solid tumours, being breast, prostate, thyroid, lung, and renal cancer the most prevalent. Bone metastases can produce skeletal-related events (SREs), defined as pathological fracture, spinal cord compression, need of bone irradiation or need of bone surgery, and hypercalcaemia. Patients with bone metastases experience pain, functional impairment and have a negative impact on their quality of life. Several imaging techniques are available for diagnosis of this disease. Bone-targeted therapies include zoledronic acid, a potent biphosfonate, and denosumab, an anti-RANKL monoclonal antibody. Both reduce the risk and/or delay the development of SREs in several types of tumours. Radium 233, an alpha-particle emitter, increases overall survival in patients with bone metastases from resistant castration prostate cancer. Multidisciplinary approach is essential and bone surgery and radiotherapy should be integrated in the treatment of bone metastases when necessary. This SEOM Guideline reviews bone metastases pathogenesis, clinical presentations, lab tests, imaging techniques for diagnosis and response assessment, bone-targeted agents, and local therapies, as radiation and surgery, and establishes recommendations for the management of patients with metastases to bone.

[Recommendations for radiological diagnosis and assessment of treatment response in lung cancer: a national consensus statement by the Spanish Society of Medical Radiology and the Spanish Society of Medical Oncology]. / Recomendaciones para el diagnóstico radiológico y la valoración de la respuesta terapéutica en el cáncer de pulmón. Consenso nacional de la Sociedad Española de Radiología Médica y la Sociedad Española de Oncología Médica.

The last decade has seen substantial progress in the diagnostic and therapeutic approach to lung cancer, thus meaning that its prognosis has improved. The Spanish Society of Medical Radiology (SERAM) and the Spanish Society of Medical Oncology (SEOM) have therefore produced a national consensus statement in order to make recommendations for radiological diagnosis and assessment of treatment response in patients with lung cancer. This expert group recommends multi-detector computed tomography (MDCT) as the technique of choice for investigating this disease. The radiology report should include a full assessment by the TNM staging system. Lastly, when the patient is on immunotherapy, response evaluation should employ not only Response Evaluation Criteria in Solid Tumours (RECIST 1.1) but also Immune-Related Response Criteria (irRC).

Biomarker testing in advanced non-small-cell lung cancer: a National Consensus of the Spanish Society of Pathology and the Spanish Society of Medical Oncology.

In 2011, the Spanish Society of Medical Oncology and the Spanish Society of Pathology started a joint project to establish recommendations on biomarker testing in patients with advanced non-small-cell lung cancer based on the current evidence. Most of these recommendations are still valid, but new evidence requires some aspects to be updated. Specifically, the recommendation about which biomarkers to test in which patients is being amended, and the best way to manage tumour samples and minimum requirements for biomarker test material are defined. Suitable techniques for testing for epidermal growth factor receptor mutations and anaplastic lymphoma kinase rearrangement are also reviewed, and a consensus is reached on which situations warrant re-biopsy.

Two biomarker-directed randomized trials in European and Chinese patients with nonsmall-cell lung cancer: the BRCA1-RAP80 Expression Customization (BREC) studies.

BACKGROUND: In a Spanish Lung Cancer Group (SLCG) phase II trial, the combination of BRCA1 and receptor-associated protein 80 (RAP80) expression was significantly associated with outcome in Caucasian patients with nonsmall-cell lung cancer (NSCLC). The SLCG therefore undertook an industry-independent collaborative randomized phase III trial comparing nonselected cisplatin-based chemotherapy with therapy customized according to BRCA1/RAP80 expression. An analogous randomized phase II trial was carried out in China under the auspices of the SLCG to evaluate the effect of BRCA1/RAP80 expression in Asian patients. PATIENTS AND METHODS: Eligibility criteria included stage IIIB-IV NSCLC and sufficient tumor specimen for molecular analysis. Randomization to the control or experimental arm was 1 : 1 in the SLCG trial and 1 : 3 in the Chinese trial. In both trials, patients in the control arm received docetaxel/cisplatin; in the experimental arm, patients with low RAP80 expression received gemcitabine/cisplatin, those with intermediate/high RAP80 expression and low/intermediate BRCA1 expression received docetaxel/cisplatin, and those with intermediate/high RAP80 expression and high BRCA1 expression received docetaxel alone. The primary end point was progression-free survival (PFS). RESULTS: Two hundred and seventy-nine patients in the SLCG trial and 124 in the Chinese trial were assessable for PFS. PFS in the control and experimental arms in the SLCG trial was 5.49 and 4.38 months, respectively [log rank P = 0.07; hazard ratio (HR) 1.28; P = 0.03]. In the Chinese trial, PFS was 4.74 and 3.78 months, respectively (log rank P = 0.82; HR 0.95; P = 0.82). CONCLUSION: Accrual was prematurely closed on the SLCG trial due to the absence of clinical benefit in the experimental over the control arm. However, the BREC studies provide proof of concept that an international, nonindustry, biomarker-directed trial is feasible. Thanks to the groundwork laid by these studies, we expect that ongoing further research on alternative biomarkers to elucidate DNA repair mechanisms will help define novel therapeutic approaches.

Lung cancer in women: an overview with special focus on Spanish women.

Lung cancer incidence is decreasing worldwide among men but rising among women due to recent changes in smoking patterns in both sexes. In Europe, the smoking epidemic has evolved different rates and times, and policy responses to it, vary substantially between countries. Differences in smoking prevalence are much more evident among European women reflecting the heterogeneity in cancer incidence rates. Other factors rather than smoking and linked to sex may increase women's susceptibility to lung cancer, such as genetic predisposition, exposure to sex hormones and molecular features, all of them linked to epidemiologic and clinical characteristics of lung cancer in women. However, biological bases of sex-specific differences are controversial and need further evaluation. This review focuses on the epidemiology and outcome concerning non-small cell lung cancer in women, with emphasis given to the Spanish population.

Adjuvant therapy with bemiparin in patients with limited-stage small cell lung cancer: results from the ABEL study.

INTRODUCTION: The haemostatic system plays an important role in the process of cancer development and spread. Anticoagulants, mainly low molecular weight heparins, could prolong survival in cancer patients, particularly in patients with lung cancer, beyond prevention of thromboembolic events. METHODS: In a multicenter, investigator-initiated, open-label, randomized, sequential study, 38 patients with newly-diagnosed, limited-stage small-cell lung cancer were randomized to receive standard chemoradiotherapy or the same therapy plus 3,500 IU daily of bemiparin for a maximum of 26 weeks. The primary outcome was progression-free survival. RESULTS: The study was terminated early due to slow recruitment. Median progression-free survival was 272 days with chemoradiotherapy alone and 410 days in the bemiparin group; hazard ratio, 2.58 (95% confidence interval [CI], 1.15-5.80); p=0.022. Median overall survival was 345 days with chemoradiotherapy alone and 1133 days in the bemiparin group; hazard ratio, 2.96 (95% CI, 1.22-7.21); p=0.017. The rate of tumor response was similar in both study arms. There was no significant between-group difference in the rates of major bleeding. Toxicity related with the experimental treatment was minimal. CONCLUSION: The addition of bemiparin to first line therapy with chemoradiotherapy significantly increases survival in patients with newly-diagnosed, limited-stage small-cell lung cancer.

Regulation of intrahepatic biliary duct morphogenesis by Claudin 15-like b.

The intrahepatic biliary ducts transport bile produced by the hepatocytes out of the liver. Defects in biliary cell differentiation and biliary duct remodeling cause a variety of congenital diseases including Alagille Syndrome and polycystic liver disease. While the molecular pathways regulating biliary cell differentiation have received increasing attention (Lemaigre, 2010), less is known about the cellular behavior underlying biliary duct remodeling. Here, we have identified a novel gene, claudin 15-like b (cldn15lb), which exhibits a unique and dynamic expression pattern in the hepatocytes and biliary epithelial cells in zebrafish. Claudins are tight junction proteins that have been implicated in maintaining epithelial polarity, regulating paracellular transport, and providing barrier function. In zebrafish cldn15lb mutant livers, tight junctions are observed between hepatocytes, but these cells show polarization defects as well as canalicular malformations. Furthermore, cldn15lb mutants show abnormalities in biliary duct morphogenesis whereby biliary epithelial cells remain clustered together and form a disorganized network. Our data suggest that Cldn15lb plays an important role in the remodeling process during biliary duct morphogenesis. Thus, cldn15lb mutants provide a novel in vivo model to study the role of tight junction proteins in the remodeling of the biliary network and hereditary cholestasis.

Predicting and managing the risk of pulmonary haemorrhage in patients with NSCLC treated with bevacizumab: a consensus report from a panel of experts.

BACKGROUND: Bevacizumab is a monoclonal antibody against vascular endothelial growth factor. Severe pulmonary haemorrhage (PH) is a rare but serious potential adverse event associated with bevacizumab therapy for advanced non-squamous non-small-cell lung cancer (NSCLC). METHODS: A panel of expert oncologists, pulmonologists and radiologists reviewed the available data to identify predictive factors for PH in order to help guide physicians using bevacizumab in patients with NSCLC. RESULTS: Patients with NSCLC are at an increased risk of PH owing to the underlying disease process. Patients with squamous histology and/or a history of grade ≥ 2 haemoptysis (≥ 2.5 ml per event) should not receive bevacizumab. No clinical or radiological features (including cavitation and central tumour location) reliably predict severe PH in bevacizumab-treated patients. Major blood vessel infiltration and bronchial vessel infiltration, encasement and abutting may predict PH; however, standardised radiological criteria for defining infiltration have not been established. Eligibility for bevacizumab is not affected by patient age, performance status or anticoagulation or antiplatelet therapy. CONCLUSIONS: An individualised risk-benefit assessment should be undertaken in all patients with NSCLC in whom bevacizumab is being considered. Further research is required to elucidate the mechanisms underlying PH and the clinical risk factors.

Brain metastases from lung cancer responding to erlotinib: the importance of EGFR mutation.

Median survival of patients with brain metastases from nonsmall cell lung cancer (NSCLC) is poor and more effective treatments are urgently needed. We have evaluated the efficacy of erlotinib in this setting and its association with activating mutations in the epidermal growth factor receptor (EGFR) gene. We retrospectively identified patients with NSCLC and brain metastases treated with erlotinib. EGFR mutations in exons 19 and 21 were analysed by direct sequencing. Efficacy and tolerability were compared according to EGFR mutational status. 69 NSCLC patients with brain metastases were identified, 17 of whom harboured EGFR mutations. Objective response rate in patients with EGFR mutations was 82.4%; no responses were observed in unselected patients (p<0.001). Median (95% CI) time to progression within the brain for patients harbouring EGFR mutations was 11.7 (7.9-15.5) months, compared to 5.8 (5.2-6.4) months for control patients whose EGFR mutational status had not been assessed (p<0.05). Overall survival was 12.9 (6.2-19.7) months and 3.1 (2.5-3.9) months (p<0.001), respectively. The toxicity of erlotinib was as expected and no differences between cohorts were observed. Erlotinib is active in brain metastases from NSCLC; this clinical benefit is related to the presence of activating mutations in exons 19 or 21 of the EGFR gene.
