Efficacy and safety of trabectedin in metastatic uterine leiomyosarcoma: A retrospective multicenter study of the Spanish ovarian cancer research group (GEICO)

Objective: We assessed trabectedin in patients with advanced uterine leiomyosarcoma (uLMS) in real-life clinical practice given according to the marketing authorization. Methods: Thirty-six women from 11 tertiary hospitals across Spain who received trabectedin after anthracyclinecontaining regimen/s were retrospectively analyzed. The primary endpoint was progression-free survival (PFS). Results: Median PFS and overall survival (OS) since starting trabectedin treatment were 5.4 (95%CI: 3.5–7.3) and 18.5 months (95%CI: 11.5–25.6), respectively. Median OS was significantly higher (P = 0.028) in patients receiving trabectedin in ≤ 2nd line (25.3 months) than in ≥ 3rd (15.1 months) and with ECOG performance status ≤ 1 at trabectedin start (19.8 months) than ECOG 2–3 (6.0 months, P = 0.013). When calculating OS since diagnosis, patients had longer OS with localized disease at diagnosis (87.4 months) vs. locally advanced (30.0 months) or metastatic (44.0 months, P = 0.041); and patients who received adjuvant therapy (87.4 months) compared with those who did not (30.0 months, P = 0.003), especially when receiving radiochemotherapy (106.7 months, P = 0.027). One patient (2.8%) had a complete response (CR) and nine patients (25.0%) achieved a partial response (PR) for an objective response rate of 27.8% with median response duration of 11 months (range: 4–93). Eighteen patients (50.0%) had disease stabilization for a disease control rate (DCR) of 77.8%. More patients receiving trabectedin in 1st-line of advanced disease achieved CR (16.7%) and PR (50.0%) than those in ≥ 2nd line/s (0.0% and 20.0%), whereas the DCR was similar across treatment lines. Reversible neutropenia was the most common grade 3/4 laboratory abnormality (19.4%). Conclusions: Trabectedin confers clinical benefit in patients with recurrent/metastatic uLMS, given after failure to an anthracycline-based regimen being comparable to those reported in clinical trials and with a manageable safety profile

Flow cytometry for fast screening and automated risk assessment in systemic light-chain amyloidosis

Early diagnosis and risk stratification are key to improve outcomes in light-chain (AL) amyloidosis. Here we used multidimensional-flow-cytometry (MFC) to characterize bone marrow (BM) plasma cells (PCs) from a series of 166 patients including newly-diagnosed AL amyloidosis (N = 94), MGUS (N = 20) and multiple myeloma (MM, N = 52) vs. healthy adults (N = 30). MFC detected clonality in virtually all AL amyloidosis (99%) patients. Furthermore, we developed an automated risk-stratification system based on BMPCs features, with independent prognostic impact on progression-free and overall survival of AL amyloidosis patients (hazard ratio: ≥ 2.9;P ≤ .03). Simultaneous assessment of the clonal PCs immunophenotypic protein expression profile and the BM cellular composition, mapped AL amyloidosis in the crossroad between MGUS and MM; however, lack of homogenously-positive CD56 expression, reduction of B-cell precursors and a predominantly-clonal PC compartment in the absence of an MM-like tumor PC expansion, emerged as hallmarks of AL amyloidosis (ROC-AUC = 0.74;P < .001), and might potentially be used as biomarkers for the identification of MGUS and MM patients, who are candidates for monitoring pre-symptomatic organ damage related to AL amyloidosis. Altogether, this study addressed the need for consensus on how to use flow cytometry in AL amyloidosis, and proposes a standardized MFC-based automated risk classification ready for implementation in clinical practice

Factors associated with therapeutic response in acromegaly diagnosed in the elderly in Spain

ContextSome reports suggest that acromegaly in elderly patients has a more benign clinical behavior and could have a better response to first-generation long-acting somatostatin receptor ligands (SRL). However, there is no specific therapeutic protocol for this special subgroup of patients. ObjectiveThis study aimed at identifying predictors of response to SRL in elderly patients. DesignMulticentric retrospective nationwide study of patients diagnosed with acromegaly at or over the age of 65 years. ResultsOne-hundred and eighteen patients (34 men, 84 women, mean age at diagnosis 71.7 +/- 5.4 years old) were included. Basal insulin-like growth factor type 1 (IGF-1) above the upper limit of normal (ULN) and growth hormone (GH) levels (mean +/- SD) were 2.7 +/- 1.4 and 11.0 +/- 11.9 ng/ml, respectively. The mean maximal tumor diameter was 12.3 +/- 6.4 mm, and up to 68.6% were macroadenoma. Seventy-two out of 118 patients (61.0%) underwent surgery as primary treatment. One-third of patients required first-line medical treatment due to a rejection of surgical treatment or non-suitability because of high surgical risk. After first-line surgery, 45/72 (63.9%) were in disease remission, and 16/34 (46.7%) of those treated with SRL had controlled disease. Patients with basal GH at diagnosis <= 6 ng/ml had lower IGF-1 levels and had smaller tumors, and more patients in this group reached control with SRL (72.7% vs. 33.3%; p < 0.04) [OR: 21.3, IC: 95% (2.4-91.1)], while male patients had a worse response [OR: 0.09, IC 95% (0.01-0.75)]. The predictive model curve obtained for SRL response showed an AUC of 0.82 CI (0.71-0.94). ConclusionsThe most frequent phenotype in newly diagnosed acromegaly in the elderly includes small adenomas and moderately high IGF-1 levels. GH at diagnosis <= 6 ng/ml and female gender, but not age per se, were associated with a greater chance of response to SRL

Non-functioning pituitary adenomas: epidemiology, clinical and postoperative outcome

Introducción. Los adenomas hipofisarios no funcionantes son el grupo tumoral más frecuente en la región selar. Suelen ser neoplasias benignas diagnosticadas por síntomas visuales u hormonales, aunque no es infrecuente detectarlos como un hallazgo casual. Objetivo. Analizar los aspectos clínicos hallados en esta enfermedad y su respuesta tras el tratamiento quirúrgico. Pacientes y métodos. En una serie de 100 casos, se analizaron datos epidemiológicos, clínicos, endocrinológicos, visuales y radiológicos antes y después del tratamiento quirúrgico, y se recogen las complicaciones relacionadas con la cirugía y el seguimiento a largo plazo. Resultados. El síntoma más frecuente en el momento del diagnóstico fue la afectación del campo visual (62%), y sólo el 7% de los adenomas se trataba de un hallazgo casual. El déficit hormonal más frecuente era el hipogonadismo hipogonadótropo (48%). Tras la cirugía se observó recuperación completa del defecto campimétrico en el 54,8% de los pacientes, con sólo un 1% de empeoramiento tras la cirugía, y la incidencia de diabetes insípida fue del 4%. La resección fue superior al 95% en el 63% de los casos, a pesar de que el porcentaje de adenomas con invasión del seno cavernoso en grados altos fue elevado (45%). Conclusiones. Aunque el síntoma más frecuente de los adenomas hipofisarios no funcionantes es la afectación campimétrica, ésta tiene una excelente respuesta a la cirugía si se realiza dentro del tiempo adecuado. El grado de invasión del seno cavernoso parece el factor más limitante para una resección quirúrgica completa.Introduction. Non-functioning pituitary adenomas are the most frequent tumor group in the sellar region. They are usually benign neoplasms diagnosed after visual or hormonal symptoms, although it is not uncommon to detect them as a casual finding. Aim. To analyze the clinical aspects found in this disease and its response after surgical treatment. Patients and methods. In a series of 100 cases, epidemiological, clinical, endocrinological, visual and radiological data were analyzed before and after surgical treatment, as well as the complications related to surgery and long-term follow-up. Results. The most frequent symptom at the time of diagnosis was visual field involvement (62%), and only the 7% of adenomas were a casual finding. The most common hormonal deficit was hypogonadotropic hypogonadism (48%). After surgery, complete recovery of the visual field defect was observed in 54.8% of the patients, only 1% worsening after surgery, and the incidence of diabetes insipidus was 4%. The resection was superior to 95% in 63% of cases, although the percentage of adenomas with invasion of the cavernous sinus in Knosp grades 3 and 4 it was high (45%). Conclusions. Although the most frequent symptom of non-functioning pituitary adenomas is campimetric involvement, it has an excellent response to surgery if it is performed within the appropriate time. The grade of invasion of the cavernous sinus is the most limiting factor for a complete surgical resectio

Maintained effectiveness of an electronic alert system to prevent venous thromboembolism among hospitalized patients

Despite current guidelines, venous thromboembolism (VTE) prophylaxis is underused. Computerized programs to encourage physicians to apply thromboprophylaxis have been shown to be effective in selected populations. Our aim was to analyze the impact of the implementation of a computer-alert system for VTE risk in all hospitalized patients of a teaching hospital. A computer program linked to the clinical record database was developed to assess all hospitalized patients' VTE risk daily. The physician responsible for patients at high risk was alerted, but remained free to order or withhold prophylaxis. Over 19,000 hospitalized, medical and surgical, adult patients between January to June 2005 (pre-intervention phase), January to June 2006 and January to June 2007 (post-intervention phase), were included. During the first semesters of 2006 and 2007, an electronic alert was sent to 32.8% and 32.2% of all hospitalized patients, respectively. Appropriate prophylaxis among alerted patients was ordered in 89.7% (2006) and 88.5% (2007) of surgical patients, and in 49.2% (2006) and 64.4% (2007) of medical patients. A sustained reduction of VTE during hospitalization was achieved, Odds ratio (OR): 0.53, 95% confidence interval (CI) (0.25-1.10) and OR: 0.51, 95%CI (0.24-1.05) during the first semesters of 2006 and 2007 respectively, the impact being significant (p < 0.05) among medical patients in 2007, OR: 0.36, 95%CI (0.12-0.98). The implementation of a computer-alert program helps physicians to assess each patient's thrombotic risk, leading to a better use of thromboprophylaxis, and a reduction in the incidence of VTE among hospitalized patients. For the first time, an intervention aimed to improve VTE prophylaxis shows maintained effectiveness over time

Cancer Histology and Natural History of Patients with Lung Cancer and Venous Thromboembolism

Background: In patients with lung cancer and venous thromboembolism (VTE), the influence of cancer histology on outcome has not been consistently evaluated. Methods: We used the RIETE registry (Registro Informatizado Enfermedad TromboEmb&oacute;lica) to compare the clinical characteristics and outcomes during anticoagulation in patients with lung cancer and VTE, according to the histology of lung cancer. Results: As of April 2022, there were 482 patients with lung cancer and VTE: adenocarcinoma 293 (61%), squamous 98 (20%), small-cell 44 (9.1%), other 47 (9.8%). The index VTE was diagnosed later in patients with squamous cancer than in those with adenocarcinoma (median, 5 vs. 2 months). In 50% of patients with adenocarcinoma, the VTE appeared within the first 90 days since cancer diagnosis. During anticoagulation (median 106 days, IQR: 45&ndash;214), 14 patients developed VTE recurrences, 15 suffered major bleeding, and 218 died: fatal pulmonary embolism 10, fatal bleeding 2. The rate of VTE recurrences was higher than the rate of major bleeding in patients with adenocarcinoma (11 vs. 6 events), and lower in those with other cancer types (3 vs. 9 events). On multivariable analysis, patients with adenocarcinoma had a non-significantly higher risk for VTE recurrences (hazard ratio [HR]: 3.79; 95%CI: 0.76&ndash;18.8), a lower risk of major bleeding (HR: 0.29; 95%CI: 0.09&ndash;0.95), and a similar risk of mortality (HR: 1.02; 95%CI: 0.76&ndash;1.36) than patients with other types of lung cancer. Conclusions: In patients with lung adenocarcinoma, the rate of VTE recurrences outweighed the rate of major bleeding. In patients with other lung cancers, it was the opposite

Cancer-associated thrombosis: Beyond clinical practice guidelines-A multidisciplinary (SEMI-SEOM-SETH) expert consensus

Despite the growing interest and improved knowledge about venous thromboembolism in cancer patients in the last years, there are still many unsolved issues. Due to the limitations of the available literature, evidence-based clinical practice guidelines are not able to give solid recommendations for challenging scenarios often present in the setting of cancer-associated thrombosis (CAT). A multidisciplinary expert panel from three scientific societies—Spanish Society of Internal Medicine (SEMI), Spanish Society of Medical Oncology (SEOM), and Spanish Society Thrombosis and Haemostasis (SETH) —agreed on 12 controversial questions regarding prevention and management of CAT, which were thoroughly reviewed to provide further guidance. The suggestions presented herein may facilitate clinical decisions in specific complex circumstances, until these can be made leaning on reliable scientific evidence
