Approximately 20% of breast cancers (BC) overexpress human epidermal growth factor receptor 2 (HER2). This subtype of BC is a clinically and biologically heterogeneous disease that was associated ...with an increased risk for the development of systemic and brain metastases and poor overall survival before anti-HER2 therapies were developed. The standard of care was dual blockade with trastuzumab and pertuzumab as first-line followed by TDM-1 as second-line. However, with the advent of new HER2-targeted monoclonal antibodies, tyrosine kinase inhibitors and antibody- drug conjugates, the clinical outcomes of patients with HER2-positive BC have changed dramatically in recent years, leading to a paradigm shift in the treatment of the disease. Notably, the development of new-generation ADCs has led to unprecedented results compared with T-DM1, currently establishing trastuzumab deruxtecan as a new standard of care in second-line. Despite the widespread availability of HER2-targeted therapies, patients with HER2-positive BC continue to face the challenges of disease progression, treatment resistance, and brain metastases. Response rate and overall life expectancy decrease with each additional line of treatment, and tumor heterogeneity remains an issue. In this review, we update the new-targeted therapeutic options for HER2-positive BC and highlight the future perspectives of treatment in this setting.
Objective
To evaluate the efficacy and safety of apalutamide prostate cancer compared to the pivotal trials patients and to identify the first subsequent therapy in a real‐world setting.
Methods
The ...study is prospective and observational based on real‐world evidence, performed by different medical disciplines and eight academics centres around Barcelona, Spain. It included all patients with metastatic hormone‐sensitive prostate cancer (mHSPC) and high‐risk non‐metastatic castration‐resistant prostate cancer (nmCRPC) treated with apalutamide from June 2018 to December 2022.
Results
Of 227 patients treated with apalutamide, 10% had ECOG‐PS 2, and 41% were diagnosed with new‐generation imaging. In the mHSPC group (209 patients), 75 years was the median age, 53% had synchronous metastases, and 22% were M1a. In the nmCRPC (18 patients), 82 years was the median age, and 81% ≤6 months had PSA doubling time. Patients achieved PSA90 in 92% of mHSPC and 50% of nmCRPC and PSA ≤0.2 in 71% of mHSPC and 39% of nmCRPC. Treatment‐related adverse events occurred in 40.1% of mHSPC and 44.4% of nmCRPC. After discontinuation of apalutamide due to disease progression, 54.5% in mHSPC and 75% in nmCRPC started chemotherapy, while after discontinuation because of adverse events, 73.3% in mHSPC and 100% in nmCRPC continued with other hormonal‐therapies.
Conclusions
The efficacy and safety of apalutamide were similar to that described in the pivotal trials, despite including an older and more comorbid population. Usually, subsequent therapies after apalutamide differed depending on the reason for discontinuation: by disease progression started chemotherapy and by adverse events hormonal sequencing.

CheckMate 743 trial demonstrated survival benefit of immunotherapy in first line in MPM with some differences in the efficacy of chemotherapy according to histology. The objective of this study is to ...characterize the impact of chemotherapy according to histology in patients diagnosed with MPM at our institution. Clinical records of all MPM patients diagnosed at Vall d'Hebron University Hospital between November 2002 and April 2020 were reviewed. Associations between clinical variables and outcomes were assessed with Cox regression models. Survival data were calculated by the Kaplan-Meier method. 189 patients were included with 76% of tumors classified as epithelioid subtype. First line chemotherapy was offered to 85% of patients. Median survival in overall population was 21.3 months (95% CI 17.2-24.3). We found that patients with epithelioid tumors had better overall survival (OS) and progression free survival (PFS). Median OS of epithelioid patients treated with first line chemotherapy was 26.7 months versus 15.0 months in non-epithelioid patients (HR 2.25 CI 95% 1.4-3.4; p < 0.001). Median PFS for patients with epithelioid tumors treated with chemotherapy was 4.8 months versus 3.6 months in non-epithelioid (HR 1.5 CI 95% 1.0-2.3; p = 0.03). The improvement of outcomes in patients with epithelioid histology was detected in patients treated with cisplatin or carboplatin. Histology was not a predictive factor for the platinum agent sensitivity (p of interaction PFS = 0.09, p of interaction OS = 0.65). In our series, patients with non-epithelioid tumors presented worse prognosis. Although epithelioid tumors exposed to cisplatin had higher PFS, histology was not a clear predictor of chemotherapy efficacy.
Collecting duct renal cell carcinoma (cdRCC), which until recently was thought to arise from the collecting ducts of Bellini in the renal medulla, is a rare and aggressive type of non-clear renal ...cell carcinoma (ncRCC), accounting for 1% of all renal tumors and with nearly 50% of patients being diagnosed with Stage IV disease. The median overall survival in this setting is less than 12 months. Several regimens of chemotherapies had been used based on morphologic and cytogenetic similarities with urothelial cell carcinoma described previously, although the prognosis still remains poor. The use of targeted therapies also did not result in favorable outcomes. Recent works using NGS have highlighted genomic alterations in
SETD2, CDKN2A, SMARCB1
, and
NF2
. Moreover, transcriptomic studies have confirmed the differences between urothelial carcinoma and cdRCC, the possible true origin of this disease in the distal convoluted tubule (DCT), differentiating from other RCC (e.g., clear cell and papillary) that derive from the proximal convoluted tubule (PCT), and enrichment in immune cells that may harbor insights in novel treatment strategies with immunotherapy and target agents. In this review, we update the current aspects of the clinical, molecular characterization, and new targeted therapeutic options for Collecting duct carcinoma and highlight the future perspectives of treatment in this setting.
Los proyectos de infraestructura energética en Colombia presentan reclamaciones contractuales de manera constante. Tradicionalmente, el equipo del proyecto y su director son los encargados de atender ...estas reclamaciones, sin que sean expertos en temas contractuales, legales o de gestión de reclamaciones. En los casos en que estas reclamaciones son atendidas por los departamentos legales de las organizaciones, se observa una falta de experticia en cuanto a la dinámica de las reclamaciones, enfocada en las características de los proyectos y en las necesidades de los equipos de proyectos. El objetivo de este artículo es analizar la importancia de la constitución de equipos de gestión de reclamaciones contractuales para proyectos de infraestructura energética como un componente de gobernanza. En esta investigación exploratoria se aplicó análisis de contenido mediante el software Maxqda Pro-2019 a casos representativos de reclamaciones contractuales, complementado con la revisión de artículos en revistas especializadas. Se analizaron cuarentaiocho casos en entidades vinculadas descentralizadas del sector de minas y energía en Colombia, y se revisaron siete documentos en Science Direct, con los criterios de “Energy + Contracts”, “Energy + Projects”, y “Projects + Claims”. Como resultados relevantes, se generó una taxonomía de diez temas que evidencian la importancia de la propuesta del equipo de gestión de las reclamaciones, y se analizó la pertinencia de la creación de la oficina de gestión de reclamaciones de proyectos (CPMO).
Immune checkpoint inhibitors (ICIs) have transformed non-small cell lung cancer (NSCLC) treatment. Unfortunately, only some patients benefit from these therapies. Thus, certain clinicopathological ...characteristics of the patients have been proposed as biomarkers of ICIs response. We assembled a retrospective cohort of 262 NSCLC patients treated with ICIs, compiled relevant clinicopathological characteristics, and studied their associations with treatment outcome using Cox proportional-hazards survival models. Additionally, we investigated the interrelations between clinicopathological features and devised a method to create a compendium associated with ICIs response by selecting those that provide non-redundant information. In multivariate analyses, ECOG performance status (hazard ratio (HR) 1.37 (95% CI 1.11 to 1.68),
< 0.005), LDH (HR 1.24 (95% CI 1.03 to 1.48),
= 0.02)) and PD-L1 negativity were associated with decreased PFS (HR 1.92 (95% CI 1.03 to 3.58),
< 0.04), whereas presentation of immune-related adverse events (irAEs) (HR 0.35 (95% CI 0.22 to 0.55,
< 0.005) or females (HR 0.52 (95% CI 0.33 to 0.80,
< 0.005) had longer progression-free survival. Additionally, numerous clinicopathological indicators were found to be interrelated. Thus, we searched for features that provide non-redundant information, and found the combination of LDH levels, irAEs, and gender to have a better association with ICIs treatment response (cross-validated c-index = 0.66). We concluded that several clinicopathological features showed prognostic value in our real-world cohort. However, some are interrelated, and compendiums of features should therefore consider these interactions. Joint assessment of LDH, irAEs, and gender may be a good prognostic compendium.
Rothmund-Thomson syndrome, a heterogeneous genodermatosis with autosomal recessive hereditary pattern, is an uncommon cancer susceptibility genetic syndrome. To date, only 400 cases have been ...reported in the literature, and the severity of the features varies among individuals with the condition. Here, we describe a 55-year-old male who had been diagnosed with Bloom Syndrome during childhood due to the suggestive physical features such as short stature, chronic facial erythema, poikiloderma in face and extremities, microtia and microcephaly. However, the genetic test demonstrated that the patient carried two pathogenic variants resulting in compound heterozygous in the RECQL4 gene (c.2269C>T and c.2547_2548delGT). He subsequently developed a calcaneal osteosarcoma, which was successfully treated, and has currently been oncologic disease-free for 3 years.
Hereditary breast and ovarian cancer (HBOC) is a syndrome defined by an increased risk of developing breast and/or ovarian cancer most commonly due to germline disease-causing variants in the BRCA1 ...and BRCA2 genes, but also other causative genes such as PALB2, ATM and CHEK2. As genetic testing becomes more prevalent and new clinical data emerge, updates of national guidelines are required to incorporate these advances in our knowledge. The aim of this work is to review the guidelines for HBOC genetic testing and clinical surveillance across European countries, mostly affiliated to the European Reference Network (ERN) for Genetic Tumor Risk Syndroms (GENTURIS). Young onset breast cancer (BC), triple negative phenotype, or bilateral BC are considered as criteria for genetic testing in all, with differences in age limits. Testing of invasive epithelial non-mucinous ovarian cancer is also universally accepted. While breast magnetic resonance imaging (MRI) is consistently recommended in high-risk individuals, age of onset for mammograms differ between 30 and 40 years. Risk-reducing mastectomy is commonly offered as an option, while risk-reducing salpingo-oophorectomy is universally recommended. The largest differences are observed with respect to ovarian surveillance prior to risk-reducing salpingo-oophorectomy and in breast surveillance for carriers of non-BRCA1/2 genes. These differences in national guidelines reflect the variations in clinical consensus that may be reached in the absence of consistent evidence for some recommendations.
