RESUMEN

BACKGROUND: Afamitresgene autoleucel (afami-cel) showed acceptable safety and promising efficacy in a phase 1 trial (NCT03132922). The aim of this study was to further evaluate the efficacy of afami-cel for the treatment of patients with HLA-A*02 and MAGE-A4-expressing advanced synovial sarcoma or myxoid round cell liposarcoma. METHODS: SPEARHEAD-1 was an open-label, non-randomised, phase 2 trial done across 23 sites in Canada, the USA, and Europe. The trial included three cohorts, of which the main investigational cohort (cohort 1) is reported here. Cohort 1 included patients with HLA-A*02, aged 16-75 years, with metastatic or unresectable synovial sarcoma or myxoid round cell liposarcoma (confirmed by cytogenetics) expressing MAGE-A4, and who had received at least one previous line of anthracycline-containing or ifosfamide-containing chemotherapy. Patients received a single intravenous dose of afami-cel (transduced dose range 1·0 × 109-10·0 × 109 T cells) after lymphodepletion. The primary endpoint was overall response rate in cohort 1, assessed by a masked independent review committee using Response Evaluation Criteria in Solid Tumours (version 1.1) in the modified intention-to-treat population (all patients who received afami-cel). Adverse events, including those of special interest (cytokine release syndrome, prolonged cytopenia, and neurotoxicity), were monitored and are reported for the modified intention-to-treat population. This trial is registered at ClinicalTrials.gov, NCT04044768; recruitment is closed and follow-up is ongoing for cohorts 1 and 2, and recruitment is open for cohort 3. FINDINGS: Between Dec 17, 2019, and July 27, 2021, 52 patients with cytogenetically confirmed synovial sarcoma (n=44) and myxoid round cell liposarcoma (n=8) were enrolled and received afami-cel in cohort 1. Patients were heavily pre-treated (median three [IQR two to four] previous lines of systemic therapy). Median follow-up time was 32·6 months (IQR 29·4-36·1). Overall response rate was 37% (19 of 52; 95% CI 24-51) overall, 39% (17 of 44; 24-55) for patients with synovial sarcoma, and 25% (two of eight; 3-65) for patients with myxoid round cell liposarcoma. Cytokine release syndrome occurred in 37 (71%) of 52 of patients (one grade 3 event). Cytopenias were the most common grade 3 or worse adverse events (lymphopenia in 50 [96%], neutropenia 44 [85%], leukopenia 42 [81%] of 52 patients). No treatment-related deaths occurred. INTERPRETATION: Afami-cel treatment resulted in durable responses in heavily pre-treated patients with HLA-A*02 and MAGE-A4-expressing synovial sarcoma. This study shows that T-cell receptor therapy can be used to effectively target solid tumours and provides rationale to expand this approach to other solid malignancies. FUNDING: Adaptimmune.

RESUMEN

Background: To date, limited evidence exists on the impact of COVID-19 in patients with soft tissue sarcoma (STS), nor about the impact of SARS-CoV-2 vaccines and recent chemotherapy on COVID-19 morbidity and mortality in this specific population. Methods: We described COVID-19 morbidity and mortality among patients with STS across 'Omicron' (15 December 2021-31 January 2022), 'Pre-vaccination' (27 February 2020-30 November 2020), and 'Alpha-Delta' phase (01 December 2020-14 December 2021) using OnCovid registry participants (NCT04393974). Case fatality rate at 28 days (CFR28) and COVID-19 severity were also described according to the SARS-CoV-2 vaccination status, while the impact of the receipt of cytotoxic chemotherapy within 4 weeks prior to COVID-19 on clinical outcomes was assessed with Inverse Probability of Treatment Weighting (IPTW) models adjusted for possible confounders. Results: Out of 3820 patients, 97 patients with STS were included. The median age at COVID-19 diagnosis was 56 years (range: 18-92), with 65 patients (67%) aged < 65 years and most patients had a low comorbidity burden (65, 67.0%). The most frequent primary tumor sites were the abdomen (56.7%) and the gynecological tract (12.4%). In total, 36 (37.1%) patients were on cytotoxic chemotherapy within 4 weeks prior to COVID-19. The overall CFR28 was 25.8%, with 38% oxygen therapy requirement, 34% rate of complications, and 32.3% of hospitalizations due to COVID-19. CFR28 (29.5%, 21.4%, and 12.5%) and all indicators of COVID-19 severity demonstrated a trend toward a numerical improvement across the pandemic phases. Similarly, vaccinated patients demonstrated numerically improved CFR28 (16.7% versus 27.7%) and COVID-19 morbidity compared with unvaccinated patients. Patients who were on chemotherapy experienced comparable CFR28 (19.4% versus 26.0%, p = 0.4803), hospitalizations (50.0% versus 44.4%, p = 0.6883), complication rates (30.6% versus 34.0%, p = 0.7381), and oxygen therapy requirement (28.1% versus 40.0%, p = 0.2755) compared to those who were not on anticancer therapy at COVID-19, findings further confirmed by the IPTW-fitted multivariable analysis. Conclusion: In this study, we demonstrate an improvement in COVID-19 outcomes in patients with STS over time. Recent exposure to chemotherapy does not impact COVID-19 morbidity and mortality and SARS-CoV-2 vaccination confers protection against adverse outcomes from COVID-19 in this patient population.


An analysis from the OnCovid registry on the impact of chemotherapy and SARS-CoV-2 vaccines on clinical outcomes of patients with soft tissue sarcoma and COVID-19 Soft tissue sarcomas (STS) are a group of rare and aggressive tumours, usually treated with high dose cytotoxic chemotherapy. To date no clear evidence exists on the impact of COVID-19 in patients with STS, nor on the potential impact of recent chemotherapy and prior SARS-CoV-2 vaccination in this specific patient population. This is the 1st study to show COVID-19 outcomes in patients with STS, highlighting a substantial vaccine efficacy with no negative impact of recent chemotherapy on COVID-19 outcomes.

RESUMEN

Soft tissue sarcomas (STS) are an uncommon and biologically heterogeneous group of tumors arising from mesenchymal cells. The incidence is estimated at five cases per 100,000 people per year. Retroperitoneal sarcomas (RPS) account for 10-15% of all STS, and their management depends on their anatomical characteristics and histotype. Due to their very low incidence, it is recommended that RPS be treated in reference centers and evaluated by an experienced multidisciplinary team (MDT). In Spain, the Spanish Group for Research in Sarcomas (GEIS) brings together experts from various specialties to promote research on sarcomas and improve treatment results. This paper summarizes the GEIS recommendations for the diagnosis, treatment, and follow-up of patients with RPS.

RESUMEN

Case summary: A case of skin fragility in an 8-year-old domestic shorthair cat with pituitary-dependent hyperadrenocorticism is described. The cat was referred to the Feline Centre at Langford Small Animal Hospital with a 2-month history of multiple skin wounds with no known traumatic aetiology. A low-dose dexamethasone suppression test was performed before referral, which was consistent with hyperadrenocorticism. On presentation, the cat had multiple cutaneous lacerations and patchy areas of alopecia. CT was performed, which revealed a pituitary mass most consistent with pituitary-dependent hyperadrenocorticism. Treatment with oral trilostane (Vetoryl; Dechra) was commenced and clinical improvement was observed; however, further extensive skin lesions as a consequence of her skin fragility resulted in euthanasia. Relevance and novel information: Hyperadrenocorticism is an uncommon endocrinopathy of cats; however, it is an important differential for skin thinning and non-healing wounds. Skin fragility remains an important factor in the consideration of appropriate treatment protocols and ongoing quality of life in these patients.

RESUMEN

We report the case of a 10-month-old girl who presented with failure to thrive and multiple small atrophic violaceous plaques, with no other findings on her physical examination. The laboratory examinations, abdominal ultrasound and bilateral hand radiography performed were unremarkable. The skin biopsy revealed fusiform cells and focal ossification in the deep dermis. The genetic study showed a pathogenic variant of GNAS.

RESUMEN

Few reports on clinical factors, treatment, and survival in children and adolescents with Central nervous system tumors in low-income and middle-income countries in Latin America exist. We retrospectively reviewed such data in all cases of patients younger than 18 years with brain tumors diagnosed in a single tertiary care center in Peru from 2007 through 2017. Variables were analyzed for association with overall survival and event-free survival by using the Kaplan-Meier method and the Cox hazards ratio regression. Seventy-five patients' data were analyzed (40 boys, 35 girls; mean age=7.7 y). The main clinical symptoms were headache, vomiting, difficulty walking, and visual disturbances. The most frequent clinical signs were hydrocephalus, cerebellar signs, visual abnormalities, and focal motor signs. The median time to diagnosis was 12 weeks. Tumor resection was performed in 68 patients, and 37 patients received postoperative radiotherapy. The most frequent histologic subtypes were low-grade gliomas and medulloblastomas. Overall survival rates at 1 and 5 years of disease were 78% (CI 95%, 0.67 to 0.86) and 74% (CI 95%, 0.62 to 0.82), respectively, and the 5-year event-free survival rate was 62% (CI 95%, 0.47 to 0.73). Although diagnosis occurred late in our cohort, the survival rate was higher than that in other Latin American countries.

RESUMEN

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.

RESUMEN

PURPOSE: Cancer survivors face higher rates of unemployment compared with individuals without a history of cancer. Compared to other cancer types, head and neck cancer (HNC) survivors face unique disease and treatment-specific issues that may limit return to work (RTW). This review aimed to determine employment outcomes of HNC survivors post-treatment and identify factors associated with RTW. METHODS: A systematic search was conducted in MEDLINE, CINAHL and PsycINFO in December 2021. Inclusion criteria included adults (≥ 18 years); completed treatment for HNC; data available on RTW post-treatment. Both quantitative and qualitative studies were considered. Studies were critically appraised and data synthesised narratively. RESULTS: Twenty-nine publications were included: 22 quantitative, four qualitative and three mixed methods. The proportion of HNC survivors who RTW ranged from 32 to 90%, with participants taking 3.6-11 months to RTW. Working in a professional role and having a supportive work environment were positively associated with RTW. CONCLUSIONS: The proportion of HNC survivors who RTW varies significantly which may be due to the heterogeneity between the studies including difference in clinical characteristics of the participants and/or sample size. Future studies that are longitudinal, adequately powered and measure a range of clinical and demographic variables are needed to better understand the RTW experience and assist development of effective RTW strategies. IMPLICATIONS FOR CANCER SURVIVORS: This review suggests potential areas for intervention, including enhanced symptom management and engaging with employers to foster supportive work environments to support RTW of HNC survivors.

RESUMEN

Resumen (analítico) El Estado chileno ha ejercido violencia contra el pueblo mapuche por generaciones, promoviendo la construcción de imaginarios en pichikeche (niños y niñas), lo que impacta en la expresión política de los movimientos sociales. Para analizar dicho impacto se usó una metodología cualitativa con diseño etnográfico. Los datos se obtuvieron mediante observación participante, entrevistas y dibujos. Participaron pichikeche de 5 a 12 años de edad, pertenecientes a cinco familias mapuche, respaldados por loncos (dirigentes) de su comunidad. Los resultados muestran que los imaginarios de dolor e incomprensión frente a la violencia, racismo y crueldad por parte del Estado pueden promover la generación de movimientos sociales que incluyen respuestas similares en colectivos de personas que carecieron de estrategias para la contención y resignificación de tales eventos traumáticos. A esto se le denomina «rebelión incubada¼.


Abstract (analytical) The Chilean State has committed violence against the Mapuche people for generations, promoting Mapuche children's construction of imaginary realities. This situation has an impact on the political expression of social movements. A qualitative methodology based on an ethnographic design was used. Data generation techniques included participant observation, interviews and pichikeche's drawings. The participants in this study were pichikeche (children) between 5 and 12 years of age from five Mapuche families supported by loncos (leaders) from their community. The results suggest that imaginary pain and misunderstanding caused by excessive and unjustified violence, racism and cruelty carried out by the State against Mapuche communities has promoted the generation of social movements. This could provoke a similar response among people who lack strategies for the containment and defining of these traumatic events, which is known as an incubated rebellion.

RESUMEN

BACKGROUND: Pediatric early warning systems (PEWS) aid in the early identification of deterioration in hospitalized children with cancer; however, they are under-used in resource-limited settings. The authors use the knowledge-to-action framework to describe the implementation strategy for Proyecto Escala de Valoracion de Alerta Temprana (EVAT), a multicenter quality-improvement collaborative, to scale-up PEWS in pediatric oncology centers in Latin America. METHODS: Proyecto EVAT mentored participating centers through an adaptable implementation strategy to: (1) monitor clinical deterioration in children with cancer, (2) contextually adapt PEWS, (3) assess barriers to using PEWS, (4) pilot and implement PEWS, (5) monitor the use of PEWS, (6) evaluate outcomes, and (7) sustain PEWS. The implementation outcomes assessed included the quality of PEWS use, the time required for implementation, and global program impact. RESULTS: From April 2017 to October 2021, 36 diverse Proyecto EVAT hospitals from 13 countries in Latin America collectively managing more than 4100 annual new pediatric cancer diagnoses successfully implemented PEWS. The time to complete all program phases varied among centers, averaging 7 months (range, 3-13 months) from PEWS pilot to implementation completion. All centers ultimately implemented PEWS and maintained high-quality PEWS use for up to 18 months after implementation. Across the 36 centers, more than 11,100 clinicians were trained in PEWS, and more than 41,000 pediatric hospital admissions had PEWS used in their care. CONCLUSIONS: Evidence-based interventions like PEWS can be successfully scaled-up regionally basis using a systematic approach that includes a collaborative network, an adaptable implementation strategy, and regional mentorship. Lessons learned can guide future programs to promote the widespread adoption of effective interventions and reduce global disparities in childhood cancer outcomes. LAY SUMMARY: Pediatric early warning systems (PEWS) are clinical tools used to identify deterioration in hospitalized children with cancer; however, implementation challenges limit their use in resource-limited settings. Proyecto EVAT is a multicenter quality-improvement collaborative to implement PEWS in 36 pediatric oncology centers in Latin America. This is the first multicenter, multinational study reporting a successful implementation strategy (Proyecto EVAT) to regionally scale-up PEWS. The lessons learned from Proyecto EVAT can inform future programs to promote the adoption of clinical interventions to globally improve childhood cancer outcomes.

RESUMEN

INTRODUCTION: We aimed to analyse health care services for adolescents and young adults (AYA) with sarcomas in Spain. METHODS: A survey was sent to all Spanish cancer centres, including questions about demographic, facilities, and treatment strategies for AYAs with sarcomas in the last 2 years. RESULTS: Thirty-five units participated in the survey, 17 paediatric and 15 adult units. There were three specialized AYA units. First line regimen varied depending on whether the treating unit was paediatric or not, for osteosarcomas, rhabdomyosarcomas, and non-rhabdomyosarcomas. By contrast, 91.4% of Ewing sarcomas were treated according to EE2012. In the relapse setting, differences between units were higher in all tumours. Additionally, 48% of the units reported not having trials for this population. CONCLUSION: There are major differences in the treatment of AYAs with sarcomas between adult and paediatric units. Enormous efforts are needed to homogenize treatments and increase the access to innovation.

RESUMEN

Erythema induratum of Bazin is a rare form of cutaneous tuberculosis, considered as part of the spectrum of tuberculids or hipersensitivity reactions to Mycobacterium tuberculosis. Treatment with biologic agents is a known risk factor for tuberculosis reactivation, especially in areas of high incidence like Latin America, which is why screening and treatment protocols must be followed before these therapies are initiated. We present a case of erythema induratum of Bazin as a reactivation of latent tuberculosis infection in a patient with rheumatoid arthritis treated with golimumab.

RESUMEN

PURPOSE: Antitumor activity in preclinical models and a phase I study of patients with dedifferentiated liposarcoma (DD-LPS) was observed with selinexor. We evaluated the clinical benefit of selinexor in patients with previously treated DD-LPS whose sarcoma progressed on approved agents. METHODS: SEAL was a phase II-III, multicenter, randomized, double-blind, placebo-controlled study. Patients age 12 years or older with advanced DD-LPS who had received two-five lines of therapy were randomly assigned (2:1) to selinexor (60 mg) or placebo twice weekly in 6-week cycles (crossover permitted). The primary end point was progression-free survival (PFS). Patients who received at least one dose of study treatment were included for safety analysis (ClinicalTrials.gov identifier: NCT02606461). RESULTS: Two hundred eighty-five patients were enrolled (selinexor, n = 188; placebo, n = 97). PFS was significantly longer with selinexor versus placebo: hazard ratio (HR) 0.70 (95% CI, 0.52 to 0.95; one-sided P = .011; medians 2.8 v 2.1 months), as was time to next treatment: HR 0.50 (95% CI, 0.37 to 0.66; one-sided P < .0001; medians 5.8 v 3.2 months). With crossover, no difference was observed in overall survival. The most common treatment-emergent adverse events of any grade versus grade 3 or 4 with selinexor were nausea (151 [80.7%] v 11 [5.9]), decreased appetite (113 [60.4%] v 14 [7.5%]), and fatigue (96 [51.3%] v 12 [6.4%]). Four (2.1%) and three (3.1%) patients died in the selinexor and placebo arms, respectively. Exploratory RNA sequencing analysis identified that the absence of CALB1 expression was associated with longer PFS with selinexor compared with placebo (median 6.9 v 2.2 months; HR, 0.19; P = .001). CONCLUSION: Patients with advanced, refractory DD-LPS showed improved PFS and time to next treatment with selinexor compared with placebo. Supportive care and dose reductions mitigated side effects of selinexor. Prospective validation of CALB1 expression as a predictive biomarker for selinexor in DD-LPS is warranted.

RESUMEN

Resumen El eritema indurado de Bazin es una tuberculosis cutánea rara, considerada una tuberculide o reacción de hipersensibilidad a Mycobacterium tuberculosis. El tratamiento con agentes biológicos es un factor de riesgo conocido para la reactivación de tuberculosis, especialmente en áreas de alta incidencia como Latinoamérica, por lo que existen protocolos de búsqueda y tratamiento antes del inicio de este tipo de terapias. Se presenta un caso clínico de eritema indurado de Bazin como reactivación de una infección tuberculosa latente en una paciente con artritis reumatoide que recibía tratamiento con golimumab.

RESUMEN

Cutaneous pseudolymphomas are reactive lymphoproliferations. The most frequent type is nodular pseudolymphoma, and to date, their ultrasonographic appearance has not been reported. We reviewed the ultrasound images of histologically confirmed nodular types of pseudolymphomas studied with 18 and 71 MHz linear probes. All lesions were predominantly hypoechoic and presented prominent vascularity. Seventy percent of cases involved dermis and hypodermis, and 30% were only dermal. Seventy percent of cases showed internal hypoechoic globules, and 100% presented a teardrop sign, more clearly detected at 71 MHz. Ultrasound can support the diagnosis, assessment of the extent, and degree of vascularity of cutaneous nodular pseudolymphomas.

RESUMEN

Resumen (analítico) El objetivo general fue conocer las actitudes hacia la sexualidad de estudiantes universitarios de las generaciones milenial y centenial. Como objetivo específico se validó un cuestionario de actitudes. Se siguió una metodología no experimental, transversal, con análisis descriptivo de respuestas de 402 estudiantes (69.1% mujeres, 30.9% hombres), con una media de edad de 20.8 años (DE 2.07). Resultaron actitudes favorables hacia: expresiones sexuales homosexuales y transexuales, eliminación de roles de género, uso del condón y re-chazo hacia la violencia en redes sociales. Se presentaron actitudes desfavorables hacia el amor y actitudes indecisas hacia las relaciones casuales. Concluimos que el conocimiento de las actitudes es fundamental en el diseño y la ejecución de políticas de salud pública dirigidas a promover y preservar la salud sexual de las generaciones actuales.


Abstract (analytical) The general objective of this study was to identify attitudes towards sexuality held by university students pertaining to the millennial and centennial generations. An attitudes questionnaire was validated as a specific objective. A non-experimental, cross-sectional methodology was followed, involving a descriptive analysis of 402 students' responses (69.1% women, 30.9% men) with a mean age of 20.8 years (SD 2.07). Favorable attitudes were found towards: homosexual and transexual expressions of sexuality, elimination of gender roles, condom use and rejection of violence in social networks. There were unfavorable attitudes toward love and marriage and a lack of definition towards casual relationships. The authors conclude that knowledge of attitudes is essential for the design and implementation of public health policies aimed at promoting and preserving the sexual health of current generations.

Among all Soft Tissue sarcomas there are some subtypes with low incidence and/or peculiar clinical behaviour, that need to be consider separately. Most of them are orphan diseases, whose biological characteristics imply a clearly different diagnostic and therapeutic approach from other more common sarcoma tumors. We present a brief and updated multidiciplinary review, focused on practical issues, aimed at helping clinicians in decision making. In this second part we review these subtypes: Alveolar Soft Part Sarcoma, Epithelioid Sarcoma, Clear Cell Sarcoma, Desmoplastic Small Round Cell Tumor, Rhabdoid Tumor, Phyllodes Tumor, Tenosynovial Giant Cell Tumors, Myoepithelial Tumor, Perivascular Epithelioid Cell Neoplasms (PEComas), Extraskeletal Myxoid Chondrosarcoma, NTRK-fusions Sarcomas. Most of them present their own radiological and histopathological feautures, that are essential to know in order to achieve early diagnosis. In some of them, molecular diagnosis is mandatory, not only in the diagnosis, but also to plan the treatment. On the other hand, and despite the low incidence, a great scientific research effort has been made to achieve new treatment opportunities for these patients even with approved indications. These include new treatments with targeted therapies and immunotherapy, which today represent possible therapeutic options. It is especially important to be attentive to new and potential avenues of research, and to promote the conduct of specific clinical trials for rare sarcomas.

RESUMEN

The aim of this study was to identify an easily reliable prognostic score that selects the subset of advanced soft tissue sarcoma (ASTS) patients with a higher benefit with trabectedin in terms of time to progression and overall survival. A retrospective series of 357 patients with ASTS treated with trabectedin as second- or further-line in 19 centers across Spain was analyzed. First, it was confirmed that patients with high growth modulation index (GMI > 1.33) were associated with the better clinical outcome. Univariate and multivariate analyses were performed to identify factors associated with a GMI > 1.33. Thus, GEISTRA score was based on metastasis free-interval (MFI ≤ 9.7 months), Karnofsky < 80%, Non L-sarcomas and better response in the previous systemic line. The median GMI was 0.82 (0-69), with 198 patients (55%) with a GMI < 1, 41 (11.5%) with a GMI 1-1.33 and 118 (33.1%) with a GMI > 1.33. The lowest GEISTRA score showed a median of time-to-progression (TTP) and overall survival (OS) of 5.7 and 19.5 months, respectively, whereas it was 1.8 and 3.1 months for TTP and OS, respectively, for the GEISTRA 4 score. This prognostic tool can contribute to better selecting candidates for trabectedin treatment in ASTS.
