SEOM-GEICAM-SOLTI clinical guidelines for early-stage breast cancer (2022)

Breast cancer is the leading cause of cancer in women in Spain and its annual incidence is rapidly increasing. Thanks to the screening programs in place, nearly 90% of breast cancer cases are detected in early and potentially curable stages, despite the COVID-19 pandemic possibly having impacted these numbers (not yet quantified). In recent years, locoregional and systemic therapies are increasingly being directed by new diagnostic tools that have improved the balance between toxicity and clinical benefit. New therapeutic strategies, such as immunotherapy, targeted drugs, and antibody–drug conjugates have also improved outcomes in some patient subgroups. This clinical practice guideline is based on a systematic review of relevant studies and on the consensus of experts from GEICAM, SOLTI, and SEOM (AU)

Immunological Landscape of HER-2 Positive Breast Cancer.

Understanding the biological aspects of immune response in HER2+ breast cancer is crucial to implementing new treatment strategies in these patients. It is well known that anti-HER2 therapy has improved survival in this population, yet a substantial percentage may relapse, creating a need within the scientific community to uncover resistance mechanisms and determine how to overcome them. This systematic review indicates the immunological mechanisms through which trastuzumab and other agents target cancer cells, also outlining the main trials studying immune checkpoint blockade. Finally, we report on anti-HER2 vaccines and include a figure exemplifying their mechanisms of action.

Possible substantive improvements in the structure of the Quality of Life in Adult Cancer Survivors (QLACS) scale? A study based on its Spanish version.

PURPOSE: Quality of Life in Adult Cancer Survivors (QLACS) scale is one of the most commonly used and validated measures to assess the Health-Related Quality of Life (HRQoL) in this population. However, there are some aspects related to its structure that still deserve consideration. The aim of this study was to test the substantive improvement over the original QLACS structure resulting from several proposals reflected in the literature. METHOD: Using a cross-sectional design and Confirmatory Factorial Analysis, we explored those proposals. Reliability, convergent validity, and factor invariance across three cancer survivorships phases (re-entry, early, and long term) were also analyzed. 1.862 post-treatment survivors of diverse cancer types completed the Spanish versions of QLACS, Brief Symptom Inventory-18 (BSI-18), and Subjective Happiness Scale (SHS). RESULTS: The original model with twelve domains, grouped (with the exception of benefits) into a single total score, versus two subtotal (Generic and Cancer-specific) obtained a good fit. The values of Cronbach's alpha, Composite reliability, Average Variance Extracted indexes, and Pearson correlations supported the internal consistency and temporal stability (interval of 2-3 weeks) of the QLACS. Results also showed its adequate convergent validity and an invariant factor structure across survival periods (re-entry survivorship, early survivorship, long-term survivorship). CONCLUSION: In its original structure, albeit the replacement of the scores on the two subscales by a total score, our results support QLACS as a valid and useful tool for the assessment of HRQoL in post-treatment cancer survivors throughout the different survival phases.

Consenso español para la prevención y el tratamiento de la infección bronquial por Pseudomonas aeruginosa en el paciente con fibrosis quística / Spanish Consensus on the Prevention and Treatment of Pseudomonas aeruginosa Bronchial Infections in Cystic Fibrosis Patients

Pseudomonas aeruginosa es el patógeno más importante en la infección broncopulmonar en fibrosis quística (FQ). Solo se erradica en la infección inicial, mientras que la reducción de su carga bacteriana es el objetivo terapéutico en la infección crónica y exacerbaciones. El cribado neonatal y la farmacociné- tica/farmacodinámica han cambiado el manejo del paciente con FQ. Se debe realizar un seguimiento microbiológico en los pacientes sin infección por P. aeruginosa. En la infección inicial se recomienda tratamiento inhalado (28 días) con colistina (0,5-2 MU/8 h), tobramicina (300 mg/12 h) o aztreonam (75 mg/8 h) con o sin ciprofloxacino oral (15-20 mg/kg/12 h, 2-3 semanas). En la infección crónica se recomienda solo vía inhalada en tratamiento continuo con colistina, o en ciclos on-off de 28 días con tobramicina o aztreonam. Durante las exacerbaciones leves-moderadas se recomienda tratamiento oral (ciprofloxacino, 2-3 semanas) y en las graves tratamiento intravenoso (-lactámico asociado a un aminoglicósido o una fluoroquinolona). Estudios futuros sustentarán la rotación y nuevas combinaciones de antimicrobianos. Se deben establecer también medidas epidemiológicas que eviten nuevas infecciones y la transmisión cruzada de P. aeruginosa

Pseudomonas aeruginosa is the main pathogen in bronchopulmonary infections in cystic fibrosis (CF) patients. It can only be eradicated at early infection stages while reduction of its bacterial load is the therapeutic goal during chronic infection or exacerbations. Neonatal screening and pharmacokinetic/pharmacodynamic knowledge has modified the management of CF-patients. A culture based microbiological follow-up should be performed in patients with no infection with P. aeruginosa. At initial infection, inhaled colistin (0,5-2 MU/tid), tobramycin (300 mg/bid) or aztreonam (75 mg/tid) with or without oral ciprofloxacin (15-20 mg/kg/bid, 2-3 weeks) are recommended. In chronic infections, treatment is based on continuous administration of colistin or with a 28-day on-off regimen with tobramycin or aztreonam. During mild-moderate exacerbations oral ciprofloxacin (2-3 weeks) can be administered while serious exacerbations must be treated with intravenous combination therapy (beta-lactam with an aminoglycoside or a fluoroquinolone). Future studies will support antibiotic rotation and/or new combination therapies. Epidemiological measures are also recommended to avoid new P. aeruginosa infections and "patient-to-patient transmission" of this pathogen

Spanish consensus on the prevention and treatment of Pseudomonas aeruginosa bronchial infections in cystic fibrosis patients.

Pseudomonas aeruginosa is the main pathogen in bronchopulmonary infections in cystic fibrosis (CF) patients. It can only be eradicated at early infection stages while reduction of its bacterial load is the therapeutic goal during chronic infection or exacerbations. Neonatal screening and pharmacokinetic/pharmacodynamic knowledge has modified the management of CF-patients. A culture based microbiological follow-up should be performed in patients with no infection with P.aeruginosa. At initial infection, inhaled colistin (0,5-2MU/tid), tobramycin (300mg/bid) or aztreonam (75mg/tid) with or without oral ciprofloxacin (15-20mg/kg/bid, 2-3weeks) are recommended.

Transmisión reciente de la tuberculosis en Madrid: utilidad de las técnicas moleculares / Recent transmission of tuberculosis in Madrid (Spain): usefulness of molecular techniques

Fundamento: En las zonas desfavorecidas de las grandes ciudades la incidencia de tuberculosis puede deberse en gran medida a la transmisión reciente de Mycobacterium tuberculosis. Pacientes y métodos: Estudio poblacional prospectivo de los pacientes diagnosticados de tuberculosis mediante cultivo en tres distritos urbanos de Madrid (población: 455.050 habitantes), en 1997 y 1998. Se cumplimentó un protocolo clinicoepidemiológico en todos los pacientes. Se incluyeron en agrupaciones los pacientes cuyos aislados tenían: a) idéntico patrón RFLP (fragmentos de restricción de longitud polimórfica) con 6 o más bandas de IS6110, o b) idéntico patrón RFLP con ó 5 bandas e idéntico patrón con la técnica de spoligotyping. Resultados: De los 207 pacientes con cultivo positivo para Mycobacterium tuberculosis se realizó RFLP a 148 (71,5 por ciento). Se identificaron 18 agrupaciones que incluían a 62 de los 148 pacientes (41,9 por ciento). Las agrupaciones contenían entre 2 y 12 casos. Los factores de riesgo asociados a la pertenencia a las distintas agrupaciones fueron la edad < 35 años (odds ratio [OR] = 4,1, intervalo de confianza [IC] del 95 por ciento: 1,9-8,9), el uso de drogas inyectadas (OR = 4,7, IC del 95 por ciento: 1,6-14,8), la infección por el VIH (OR = 2,7, IC: del 95 por ciento: 1,1-6,8) y la estancia previa en prisión (OR = 2,9, IC del 95 por ciento: 1,2-7,2). La investigación epidemiológica confirmó la transmisión reciente de la enfermedad en el 27 por ciento de los casos agrupados. Conclusiones: Una elevada proporción de los casos de tuberculosis diagnosticados en personas residentes en el sur de la ciudad de Madrid son resultado de transmisión reciente de la enfermedad. La investigación epidemiológica y molecular realizadas conjuntamente aportan información valiosa para el control de la enfermedad (AU)
