Maintenance olaparib in patients with platinum-sensitive relapsed ovarian cancer: Outcomes by somatic and germline BRCA and other homologous recombination repair gene mutation status in the ORZORA trial.

BACKGROUND: The open-label, single-arm, multicenter ORZORA trial (NCT02476968) evaluated the efficacy and safety of maintenance olaparib in patients with platinum-sensitive relapsed ovarian cancer (PSR OC) who had tumor BRCA mutations (BRCAm) of germline (g) or somatic (s) origin or non-BRCA homologous recombination repair mutations (HRRm) and were in response to their most recent platinum-based chemotherapy after ≥2 lines of treatment. METHODS: Patients received maintenance olaparib capsules (400 mg twice daily) until disease progression. Prospective central testing at screening determined tumor BRCAm status and subsequent testing determined gBRCAm or sBRCAm status. Patients with predefined non-BRCA HRRm were assigned to an exploratory cohort. The co-primary endpoints were investigator-assessed progression-free survival (PFS; modified Response Evaluation Criteria in Solid Tumors v1.1) in BRCAm and sBRCAm cohorts. Secondary endpoints included health-related quality of life (HRQoL) and tolerability. RESULTS: 177 patients received olaparib. At the primary data cut-off (17 April 2020), the median follow-up for PFS in the BRCAm cohort was 22.3 months. The median PFS (95% CI) in BRCAm, sBRCAm, gBRCAm and non-BRCA HRRm cohorts was 18.0 (14.3-22.1), 16.6 (12.4-22.2), 19.3 (14.3-27.6) and 16.4 (10.9-19.3) months, respectively. Most patients with BRCAm reported improvements (21.8%) or no change (68.7%) in HRQoL and the safety profile was as expected. CONCLUSIONS: Maintenance olaparib had similar clinical activity in PSR OC patients with sBRCAm and those with any BRCAm. Activity was also observed in patients with a non-BRCA HRRm. ORZORA further supports use of maintenance olaparib in all patients with BRCA-mutated, including sBRCA-mutated, PSR OC.

Efficacy and Safety of Mirvetuximab Soravtansine in Patients With Platinum-Resistant Ovarian Cancer With High Folate Receptor Alpha Expression: Results From the SORAYA Study.

PURPOSE: Single-agent chemotherapies have limited activity and considerable toxicity in patients with platinum-resistant epithelial ovarian cancer (PROC). Mirvetuximab soravtansine (MIRV) is an antibody-drug conjugate targeting folate receptor α (FRα). SORAYA is a single-arm, phase II study evaluating efficacy and safety of MIRV in patients with PROC. METHODS: SORAYA enrolled FRα-high patients with PROC who had received one to three prior therapies, including required bevacizumab. The primary end point was confirmed objective response rate (ORR) by investigator; duration of response was the key secondary end point. RESULTS: One hundred six patients were enrolled; 105 were evaluable for efficacy. All patients had received prior bevacizumab, 51% had three prior lines of therapy, and 48% received a prior poly ADP-ribose polymerase inhibitor. Median follow-up was 13.4 months. ORR was 32.4% (95% CI, 23.6 to 42.2), including five complete and 29 partial responses. The median duration of response was 6.9 months (95% CI, 5.6 to 9.7). In patients with one to two priors, the ORR by investigator was 35.3% (95% CI, 22.4 to 49.9) and in patients with three priors was 30.2% (95% CI, 18.3 to 44.3). The ORR by investigator was 38.0% (95% CI, 24.7 to 52.8) in patients with prior poly ADP-ribose polymerase inhibitor exposure and 27.5% (95% CI, 15.9 to 41.7) in those without. The most common treatment-related adverse events (all grade and grade 3-4) were blurred vision (41% and 6%), keratopathy (29% and 9%), and nausea (29% and 0%). Treatment-related adverse events led to dose delays, reductions, and discontinuations in 33%, 20%, and 9% of patients, respectively. CONCLUSION: MIRV demonstrated consistent clinically meaningful antitumor activity and favorable tolerability and safety in patients with FRα-high PROC who had received up to three prior therapies, including bevacizumab, representing an important advance for this biomarker-selected population.

Lung function and radiological findings 1 year after COVID-19: a prospective follow-up.

BACKGROUND: The coronavirus disease (COVID-19) pandemic has already affected more than 400 million people, with increasing numbers of survivors. These data indicate that a myriad of people may be affected by pulmonary sequelae of the infection. The aim of this study was to evaluate pulmonary sequelae in patients with bilateral COVID-19 pneumonia according to severity 1 year after hospital discharge. METHODS: COVID-FIBROTIC is a multicenter prospective observational cohort study for admitted patients with bilateral COVID-19 pneumonia. Pulmonary functional outcomes and chest computed tomography sequelae were analyzed 12 months after hospital discharge and we classified patients into three groups according to severity. A post hoc analysis model was designed to establish how functional test changed between groups and over time. A multivariable logistic regression model was created to study prognostic factors for lung diffusion impairment and radiological fibrotic-like changes at 12 months. RESULTS: Among 488 hospitalized patients with COVID-19 pneumonia, 284 patients had completed the entire evaluation at 12 months. Median age was 60.5 ± 11.9 and 55.3% were men. We found between-group differences in male sex, length of hospital stay, radiological involvement and inflammatory laboratory parameters. The functional evaluation of pulmonary sequelae showed that severe patients had statistically worse levels of lung diffusion at 2 months but no between group differences were found in subsequent controls. At 12-month follow up, however, we found impaired lung diffusion in 39.8% unrelated to severity. Radiological fibrotic-like changes at 12 months were reported in 22.7% of patients (102/448), only associated with radiological involvement at admission (OR: 1.55, 95% CI 1.06-2.38; p = 0.02) and LDH (OR: 0.99, 95% CI 0.98-0.99; p = 0.046). CONCLUSION: Our data suggest that a significant percentage of individuals would develop pulmonary sequelae after COVID 19 pneumonia, regardless of severity of the acute process.

Impact of disease progression on health-related quality of life of advanced ovarian cancer patients - Pooled analysis from the PRIMA trial.

OBJECTIVE: Progression-free survival (PFS) is an important early efficacy endpoint in ovarian cancer (OC) and its relevance to patients should be assessed. PRIMA, a phase III trial, assessed niraparib in patients with OC; this post hoc analysis examined the relationship between disease progression in OC and health-related quality of life (HRQoL). METHODS: The PRIMA trial randomized patients with advanced OC responsive to first-line platinum-based chemotherapy to once daily maintenance oral niraparib or placebo. This post hoc analysis evaluated the impact of disease progression on HRQoL by comparing HRQoL at the last visit pre-progression to end of treatment (EoT), and after 4, 8, 12, and 24 weeks. Assessments included the Functional Assessment of Cancer Therapy-Ovarian Symptom Index (FOSI), the European Quality of Life Five Dimension Five Level questionnaire (EQ-5D-5L) and EQ Visual Analogue Scale (EQ-VAS), the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (EORTC-QLQ-C30), and the EORTC Quality of Life Questionnaire Ovarian Cancer module (EORTC-QLQ-OV28). RESULTS: This post hoc analysis included 733 patients. Mean FOSI, EQ-5D-5L, and EQ-VAS scores deteriorated from last visit pre-progression to EoT and remained low up to 24-week follow-up. Least squares mean changes from last visit pre-progression to EoT were -2.1 (95% confidence interval -2.4, -1.7) for FOSI, -4.6 (-5.6, -3.5) for the EQ-5D-5L index, and -7.9 (-9.6, -6.3) for EQ-VAS. CONCLUSIONS: Disease progression negatively impacted HRQoL in patients with OC. PFS is clinically relevant, and prolonging PFS may preserve HRQoL.

Efficacy and safety results from GEICO 1205, a randomized phase II trial of neoadjuvant chemotherapy with or without bevacizumab for advanced epithelial ovarian cancer.

BACKGROUND: Bevacizumab is an approved treatment after primary debulking surgery for ovarian cancer. However, there is limited information on bevacizumab added to neoadjuvant chemotherapy before interval debulking surgery. OBJECTIVE: To evaluate neoadjuvant bevacizumab in a randomized phase II trial. METHODS: Patients with newly diagnosed stage III/IV high-grade serous/endometrioid ovarian cancer were randomized to receive four cycles of neoadjuvant chemotherapy with or without ≥3 cycles of bevacizumab 15 mg/kg every 3 weeks. After interval debulking surgery, all patients received post-operative chemotherapy (three cycles) and bevacizumab for 15 months. The primary end point was complete macroscopic response rate at interval debulking surgery. RESULTS: Of 68 patients randomized, 64 completed four neoadjuvant cycles; 22 of 33 (67%) in the chemotherapy-alone arm and 31 of 35 (89%) in the bevacizumab arm (p=0.029) underwent surgery. The complete macroscopic response rate did not differ between treatment arms in either the intention-to-treat population of 68 patients (6.1% vs 5.7%, respectively; p=0.25) or the 55 patients who underwent surgery (8.3% vs 6.5%; p=1.00). There was no difference in complete cytoreduction rate or progression-free survival between the treatment arms. During neoadjuvant therapy, grade ≥3 adverse events were more common with chemotherapy alone than with bevacizumab (61% vs 29%, respectively; p=0.008). Intestinal (sub)occlusion, fatigue/asthenia, abdominal infection, and thrombocytopenia were less frequent with bevacizumab. The incidence of grade ≥3 adverse events was 9% in the control arm versus 16% in the experimental arm in the month after surgery. CONCLUSIONS: Adding three to four pre-operative cycles of bevacizumab to neoadjuvant chemotherapy for unresectable disease did not improve the complete macroscopic response rate or surgical outcome, but improved surgical operability without increasing toxicity. These results support the early integration of bevacizumab in carefully selected high-risk patients requiring neoadjuvant chemotherapy for initially unresectable ovarian cancer.

Prevalence of persistent blood eosinophilia: relation to outcomes in patients with COPD.

The impact of blood eosinophilia in chronic obstructive pulmonary disease (COPD) remains controversial.To evaluate the prevalence and stability of a high level of blood eosinophils (≥300 cells·µL-1) and its relationship to outcomes, we determined blood eosinophils at baseline and over 2 years in 424 COPD patients (forced expiratory volume in 1 s (FEV1) 60% predicted) and 67 smokers without COPD from the CHAIN cohort, and in 308 COPD patients (FEV1 60% predicted) in the BODE cohort. We related eosinophil levels to exacerbations and survival using Cox hazard analysis.In COPD patients, 15.8% in the CHAIN cohort and 12.3% in the BODE cohort had persistently elevated blood eosinophils at all three visits. A significant proportion (43.8%) of patients had counts that oscillated above and below the cut-off points, while the rest had persistent eosinophil levels <300 cells·µL-1 A similar eosinophil blood pattern was observed in controls. Exacerbation rates did not differ in patients with and without eosinophilia. All-cause mortality was lower in patients with high eosinophils compared with those with values <300 cells·µL-1 (15.8% versus 33.7%; p=0.026).In patients with COPD, blood eosinophils ≥300 cells·µL-1 persisting over 2 years was not a risk factor for COPD exacerbations. High eosinophil count was associated with better survival.

Disseminated Oligodendroglial-like Leptomeningeal Tumor of Childhood: A Distinctive Entity Revised and Correlated with Pathology.

Disseminated oligodendroglial-like leptomeningeal tumor is a recently acknowledged entity whose radiological characteristics have rarely been discussed before. Typical of the childhood period, it should be differentiated clinically and radiographically from granulomatous or infectious conditions such as tuberculous meningitis, which is more common in this age group. The key to the diagnosis, even at an early stage, might be the presence of tiny T2 hyperintense lesions on the surface of the brain or spine. When suspected, a meningeal biopsy should be performed to confirm the diagnostic.

The Genus Criodion (Audinet-Serville, 1833) (Coleoptera, Cerambycidae): First Record for Panama.

BACKGROUND: The Cerambycidae are one of the largest beetle families. Cerambycid beetles are found on all continents, but the tropics are extremely rich in this species. The genus Criodion (Audinet-Serville, 1833) includes 13 species in the Neotropical Region, two of which occur in Central America. Panama has a high biodiversity, yet a small number of sites have been extensively studied. In this contribution, new distributional data are given for C. cinereum (Olivier, 1795) and C. tuberculatum Gahan, 1892. NEW INFORMATION: Two species of the genus Criodion (Audinet-Serville, 1833) are recorded for first time in Panama, Criodion cinereum (Olivier, 1795) and Criodion tuberculatum Gahan, 1892. Relevant details are presented for each species.

Differential Effect of Modified Medical Research Council Dyspnea, COPD Assessment Test, and Clinical COPD Questionnaire for Symptoms Evaluation Within the New GOLD Staging and Mortality in COPD.

OBJECTIVE: The modified Medical Research Council (mMRC) dyspnea, the COPD Assessment Test (CAT), and the Clinical COPD Questionnaire (CCQ) have been interchangeably proposed by GOLD (Global Initiative for Chronic Obstructive Lung Disease) for assessing symptoms in patients with COPD. However, there are no data on the prognostic value of these tools in terms of mortality. We endeavored to evaluate the prognostic value of the CAT and CCQ scores and compare them with mMRC dyspnea. METHODS: We analyzed the ability of these tests to predict mortality in an observational cohort of 768 patients with COPD (82% men; FEV1, 60%) from the COPD History Assessment in Spain (CHAIN) study, a multicenter observational Spanish cohort, who were monitored annually for a mean follow-up time of 38 months. RESULTS: Subjects who died (n = 73; 9.5%) had higher CAT (14 vs 11, P = .022), CCQ (1.6 vs 1.3, P = .033), and mMRC dyspnea scores (2 vs 1, P < .001) than survivors. Receiver operating characteristic analysis showed that higher CAT, CCQ, and mMRC dyspnea scores were associated with higher mortality (area under the curve: 0.589, 0.588, and 0.649, respectively). CAT scores ≥ 17 and CCQ scores > 2.5 provided a similar sensitivity than mMRC dyspnea scores ≥ 2 to predict all-cause mortality. CONCLUSIONS: The CAT and the CCQ have similar ability for predicting all-cause mortality in patients with COPD, but were inferior to mMRC dyspnea scores. We suggest new thresholds for CAT and CCQ scores based on mortality risk that could be useful for the new GOLD grading classification.

New GOLD classification: longitudinal data on group assignment.

RATIONALE: Little is known about the longitudinal changes associated with using the 2013 update of the multidimensional GOLD strategy for chronic obstructive pulmonary disease (COPD). OBJECTIVE: To determine the COPD patient distribution of the new GOLD proposal and evaluate how this classification changes over one year compared with the previous GOLD staging based on spirometry only. METHODS: We analyzed data from the CHAIN study, a multicenter observational Spanish cohort of COPD patients who are monitored annually. Categories were defined according to the proposed GOLD: FEV1%, mMRC dyspnea, COPD Assessment Test (CAT), Clinical COPD Questionnaire (CCQ), and exacerbations-hospitalizations. One-year follow-up information was available for all variables except CCQ data. RESULTS: At baseline, 828 stable COPD patients were evaluated. On the basis of mMRC dyspnea versus CAT, the patients were distributed as follows: 38.2% vs. 27.2% in group A, 17.6% vs. 28.3% in group B, 15.8% vs. 12.9% in group C, and 28.4% vs. 31.6% in group D. Information was available for 526 patients at one year: 64.2% of patients remained in the same group but groups C and D show different degrees of variability. The annual progression by group was mainly associated with one-year changes in CAT scores (RR, 1.138; 95%CI: 1.074-1.206) and BODE index values (RR, 2.012; 95%CI: 1.487-2.722). CONCLUSIONS: In the new GOLD grading classification, the type of tool used to determine the level of symptoms can substantially alter the group assignment. A change in category after one year was associated with longitudinal changes in the CAT and BODE index.

Influencia de la inmigración en los patrones de transmisión de la tuberculosis en Castellón (2004–2007) / Influence of immigration on tuberculosis transmission patterns in Castellón, Spain (2004–2007)

Objetivo: Describir los patrones de transmisión de la tuberculosis en Castellón en un periodo de importantes cambios demográficos. Métodos: Estudio prospectivo descriptivo de los pacientes con cultivo positivo en la provincia de Castellón entre 2004 y2007. Se describen los pacientes por año y nacionalidad, y se cotejan con los casos declarados a la Dirección General de Salud Pública (DGSP). Se estudia la población con patrón molecular disponible por RFLP (restriction fragment length polymorphism) y se analizan las variables de los pacientes agrupados (clusters) a partir de los datos de la DGSP y del Programa de Gestión del Laboratorio.Resultados: Según la DGSP, la tasa global de tuberculosis por 100.000 habitantes en la provincia de Castellón fue de 15,7 en 2004, 19,9 en 2005, 18,2 en 2006 y 17,5 en 2007. En nuestro laboratorio se identificaron las cepas de 301 pacientes, que suponen el 77% (301/390) de los casos declarados y el94% (301/321) aquellos con cultivo positivo. El porcentaje de tuberculosis en extranjeros aumentó hasta superar el 50% en 2007. Se disponía de estudio molecular en el 95% de los casos (286), con un 58% deespañoles y un 42% de extranjeros. El porcentaje de agregación fue del 40%, con un 30% de clusters mixtos.Según el estudio convencional de contactos, el 85% de los pacientes en cluster habían sido considerados casos aislados. Conclusiones: El aumento de la tasa de tuberculosis en Castellón se debe, principalmente, al creciente número de los casos en extranjeros. Disponer del estudio molecular de todos los pacientes con cultivo positivo nos ha permitido analizar cómo y dónde se transmite la tuberculosis. El 40% de los pacientes se agruparon en clusters, y eran mixtos un tercio de ellos, lo que indica una elevada integración de los inmigrantes (AU)

Background: This study aimed to identify tuberculosis transmission patterns in Castellón in a period ofmajor demographic changes. Methods: A prospective study of patients with positive culture in the province of Castellon over a 4-yearperiod (2004–2007) was carried out. Cases were described by year and nationality and were compared with those reported to the Department of Public Health. We studied the population with available molecular patterns, identified through restriction fragment length polymorphism (RFLP) and analyzed the variables from patient clusters, based on data collected in surveys of the Department of Health and the Laboratory Management Program.

Medidas de bioseguridad en una sala de disección de anatomía patológica / Biosecurity measures in a dissecting room pathology

El objetivo principal es analizar las medidas de bioseguridad en el laboratorio de disecciÓn de anatomía patolÓgica del hospital Max Peralta en Cartago. Con el fin de valorar los riesgos asociados con la exposición al forma debido, se utilizaron las guías de referencia de la Administración en Salud y Seguridad Ocuapcional (OSHA) y del Instituto Nacional de Salud y Seguridad (NIOSH). Tomando en cuenta tres variables: uso de medidas de protección, diseño del laboratorio y ventilación. Los datos fueron analizados en el mes de diciembre del 2009. Se encontró que en la sala de disección no existe un adecuado sistema de ventilación para evitar la acumulación de formalina en el aire. El personal que labora allí si toma las medidas de seguridad para protección personal. El diseño de la sala cumple con la mayor parte de los requerimientos tales como que se encuentre separado del area de oficinas, presencia de lavamanos y mesas de materiales resistente que permitan una fácil limpieza y desinfección. Pero los estantes que se encuentran en el pasillo principal en los cuales se almacenan tejidos para la docencia, no se encuentran asegurados a la pared, lo que evidencia un potencial riesgo en caso de sismo o incendio al obstruir la única salida del laboratorio. Conclusión: Es importante identificar los riesgos en el lugar de trabajo que podrían causar daño. Deben anticiparse y evaluarse cuidadosamente la prevención de riesgo y salud, para que se incorporen medidas de diseño recomendadas según sea posible. Si embargo, no importa que tan bien estructurado esté un laboratorio, pues su uso inapropiado puede producir riesgos laborales...
