ABSTRACT

Genomic Instability (GI) is a transversal phenomenon shared by several tumor types that provide both prognostic and predictive information. In the context of high-grade serous ovarian cancer (HGSOC), response to DNA-damaging agents such as platinum-based and poly(ADP-ribose) polymerase inhibitors (PARPi) has been closely linked to deficiencies in the DNA repair machinery by homologous recombination repair (HRR) and GI. In this study, we have developed the Scarface score, an integrative algorithm based on genomic and transcriptomic data obtained from the NGS analysis of a prospective GEICO cohort of 190 formalin-fixed paraffin-embedded (FFPE) tumor samples from patients diagnosed with HGSOC with a median follow up of 31.03 months (5.87-159.27 months). In the first step, three single-source models, including the SNP-based model (accuracy = 0.8077), analyzing 8 SNPs distributed along the genome; the GI-based model (accuracy = 0.9038) interrogating 28 parameters of GI; and the HTG-based model (accuracy = 0.8077), evaluating the expression of 7 genes related with tumor biology; were proved to predict response. Then, an ensemble model called the Scarface score was found to predict response to DNA-damaging agents with an accuracy of 0.9615 and a kappa index of 0.9128 (p < 0.0001). The Scarface Score approaches the routine establishment of GI in the clinical setting, enabling its incorporation as a predictive and prognostic tool in the management of HGSOC.

ABSTRACT

OBJECTIVES: Adding maintenance olaparib to bevacizumab provided a significant progression-free survival (PFS) benefit in patients with newly diagnosed, advanced ovarian cancer in the randomized, double-blind PAOLA-1/ENGOT-ov25 trial (NCT02477644). We analyzed PFS by clinical risk and biomarker status. METHODS: Patients received olaparib 300 mg twice daily for up to 24 months plus bevacizumab 15 mg/kg every 3 weeks for up to 15 months in total, or placebo plus bevacizumab. This post hoc exploratory analysis evaluated PFS in patients classified as higher risk (stage III with upfront surgery and residual disease or neoadjuvant chemotherapy; stage IV) or lower risk (stage III with upfront surgery and no residual disease), and by biomarker status. RESULTS: Of 806 randomized patients, 74% were higher risk and 26% were lower risk. After a median 22.9 months of follow-up, PFS favored olaparib plus bevacizumab versus placebo plus bevacizumab in higher-risk patients (hazard ratio [HR] 0.60; 95% confidence interval [CI] 0.49-0.74) and lower-risk patients (0.46; 0.30-0.72). Olaparib plus bevacizumab provided a substantial PFS benefit versus bevacizumab alone in the homologous recombination deficiency (HRD)-positive subgroup (higher risk: HR 0.39; 95% CI 0.28-0.54 and lower risk: 0.15; 0.07-0.30), with 24-month PFS rates in lower-risk patients of 90% versus 43%, respectively (Kaplan-Meier estimates). CONCLUSIONS: In PAOLA-1, maintenance olaparib plus bevacizumab provided a substantial PFS benefit in HRD-positive patients with a reduction of risk of progression or death of 61% in the higher-risk group and of 85% in the lower-risk group compared with bevacizumab alone.

ABSTRACT

Ovarian cancer is the seventh most common type of cancer and the fifth leading cause of cancer death among women worldwide. The current usual therapeutic approach in this disease includes optimal cytoreductive therapy followed by platinum-based adjuvant chemotherapy, along with neoadjuvant chemotherapy prior to surgery in selected cases. The platinum-free interval (PFI) continues to be the most useful tool to assist in the selection of the subsequent therapy and to predict response to treatment. The combination of trabectedin and pegylated liposomal doxorubicin (PLD) is useful in patients with partially platinum-sensitive recurrent ovarian cancer, in patients who have previously received two or more platinum-based chemotherapy regimens, in patients who have already experienced a platinum-induced hypersensitivity reaction and in patients who have previously failed to respond to a platinum-based treatment. CASE PRESENTATION: A 64-years-old postmenopausal woman with pain, abdominal distension, and an altered intestinal transit and with partially platinum-sensitive recurrent ovarian cancer, was successfully treated with a second line of trabectedin chemotherapy in combination with PLD, followed by trabectedin in monotherapy. This case proves the effectiveness of the combination of trabectedin and PLD and demonstrates how the administration of trabectedin, even in monotherapy, allows to maintain an adequate clinical response with good tolerance to the treatment during more than two years of drug administration.

ABSTRACT

Objetivo: Realizar un análisis modal de fallos y efectos (AMFE) aplicado a la utilización de jeringas orales. Métodos: Un grupo multidisciplinar dentro del Comité de Seguridad analizó las etapas en la administración oral de los medicamentos líquidos, identificándose las más críticas y estableciendo modos potenciales de fallo que podrían producir un error. El riesgo asociado a cada modo de fallo se calculó utilizando el número de prioridad de riesgo (NPR). Se sugirieron acciones preventivas. Resultados: Se identificaron cinco modos de fallo, todos clasificados de alto riesgo (NPR>100). Siete de las ocho recomendaciones fueron implementadas. Conclusiones: La aplicación de la metodología AMFE ha sido una herramienta muy útil que ha permitido conocer los riesgos, analizar las causas que los pueden provocar y saber los efectos que tienen en la seguridad del paciente; todo ello con el fin de implantar acciones para reducirlos (AU)


Objective: To carry out a Failure Mode and Effects Analysis (FMEA) to the use of oral syringes. Methods: A multidisciplinary team was assembled within the Safety Committee. The stages of oral administration process of liquid medication were analysed, identifying the most critical and establishing the potential modes of failure that can cause errors. The impact associated with each mode of failure was calculated using the Risk Priority Number (RPN). Preventive actions were proposed. Results: Five failure modes were identified, all classified as high risk (RPN> 100). Seven of the eight preventive actions were implemented. Conclusions: The FMEA methodology was a useful tool. It has allowed to know the risks, analyse the causes that cause them, their effects on patient safety and the measures to reduce them (AU)

ABSTRACT

Parasellar and hypothalamic metastases are uncommon. Their principal clinical manifestation is diabetes insipidus. Associated hypopituitarism is very rare. We report the case of a 54-year-old man with small cell lung cancer and hypopituitarism. A brain magnetic resonance imaging scan revealed a mass in the anterior region of the third ventricle with no clear etiology. The patient began chemotherapy treatment and the mass disappeared, which confirmed the diagnosis of secondary hypopituitarism caused by hypothalamic metastasis from small cell lung cancer.

ABSTRACT

Las metástasis en la región selar e hipotalámica son raras y la principal manifestación clínica es la diabetes insípida. Un hipopituitarismo concomitante se produce en muy pocas ocasiones. Presentamos el caso de un varón de 54 años con carcinoma microcítico de pulmón e hipopituitarismo. Una resonancia magnética cerebral reveló una lesión en la cara anterior del tercer ventrículo sin etiología clara. El paciente inició tratamiento con quimioterapia y la lesión desapareció. Por lo tanto, el paciente fue diagnosticado de hipopitituarismo secundario a metástasis hipotalámica de carcinoma microcítico de pulmón (AU)
