RESUMO
INTRODUCTION: Hypofractionated whole breast irradiation (hWBI) and intraoperative radiotherapy (IORT) could be associated in breast cancer patients showing high-risk factors of local recurrence after breast conserving therapy (BSC). The aim of this trial was to evaluate, for the first time, the toxicity and cosmesis of hWBI after photon-IORT in high-risk patients treated by adjuvant chemotherapy. MATERIALS AND METHODS: Thirty-one high-risk localized breast cancer patients treated by BCS, IORT (20 Gy), and adjuvant chemotherapy were included from February 2019 to August 2020 in this prospective trial, of hWBI (40.5 Gy/2.67 Gy/15 fractions). Acute and late toxicity (CTCAEv5.0) and cosmesis (Harvard scale), were assessed after treatment. RESULTS: All patients completed their treatment and were evaluable after treatment. No patients showed severe (G3) acute/late toxicity. Excellent/good cosmesis at least 6 months after completing the treatment, was present in 93.6% of the patients. CONCLUSION: hWBI in high-risk localized breast cancer patients treated by chemotherapy seems to have similar toxicity and cosmetic results than conventionally fractionated WBI in combination to photon-IORT after BCS.

INTRODUCTION: Hypofractionated whole breast irradiation (HWBI) is the current standard of treatment after breast conservative surgery (BCS). Intraoperative radiotherapy (IORT) must be associated to WBI in patients showing high-risk factors of local recurrence in the definitive pathology report. The aim of this trial was to evaluate, for the first time, the acute toxicity and cosmesis of HWBI after photon-IORT. MATERIALS AND METHODS: Twenty-six luminal breast cancer patients treated by BCS and IORT(20 Gy) were included between February and December 2019, in this prospective trial, of adjuvant HWBI (40.5 Gy/2.67 Gy/15 fractions). Acute toxicity (CTCAEv5.0) and cosmesis (Harvard scale), were assessed 3 months after treatment. RESULTS: All patients completed their treatment without interruptions. All cases were evaluable 3 months after treatment showing no toxicity ≥ G3 and excellent/good cosmesis assessment in 88% of the patients. CONCLUSION: HWBI seems to have similar acute toxicity and cosmesis results than conventionally fractionated WBI in combination to photon-IORT after BCS.

INTRODUCTION: Clinical studies results show that policosanol (20 mg/day) + aspirin therapy had benefits versus placebo + aspirin to patients with recent non-cardioembolic ischemic stroke. AIM: To analyze the policosanol treatment effects in the hypertensive patients included in two non-cardioembolic ischemic stroke recovery trials. PATIENTS AND METHODS: Hypertensive patients with a modified Rankin Scale (mRS) score 2 to 4 were randomized, within 30 days of onset, to policosanol + aspirin or placebo + aspirin, for six months. The primary outcome was mRS score reduction. RESULTS: One hundred forty two hypertensive patients (mean age: 66 years) were included in the analysis. Policosanol + aspirin decreased significantly the mRS score mean from the first interim check-up. The policosanol treatment effect did not wear off, on the contrary, even improved after six months therapy. More over, policosanol + aspirin (80.3%) treatment achieved significant results (mRS <= 1), whereas the placebo + aspirin did not (8.5%). Two patients discontinued and four (two from each group) referred mild adverse events. CONCLUSIONS: The treatment for six months with policosanol + aspirin in hypertensive patients who had suffered a non-cardioembolic ischemic stroke proved to be more effective than the placebo + aspirin treatment in the functional recovery of these patients.
TITLE: Efectos del policosanol en la recuperacion funcional de pacientes hipertensos con ictus isquemico no cardioembolico.Introduccion. Los resultados de los estudios clinicos muestran que el tratamiento con policosanol (20 mg/dia) + aspirina produce beneficios frente a placebo + aspirina en pacientes con ictus isquemico no cardioembolico reciente. Objetivo. Analizar los efectos del tratamiento con policosanol en pacientes hipertensos incluidos en dos ensayos de recuperacion de ictus isquemico no cardioembolico. Pacientes y metodos. Pacientes hipertensos que sufrieron un ictus en los 30 dias previos y que, con una puntuacion de 2 a 4 en la escala de Rankin modificada (mRS), se distribuyeron aleatoriamente en dos grupos y recibieron policosanol + aspirina o placebo + aspirina durante seis meses. La variable primaria de eficacia fue la reduccion de la puntuacion en la mRS. Resultados. Se incluyo a un total de 142 pacientes hipertensos (edad media: 66 años) en el analisis. El policosanol + aspirina disminuyo significativamente la puntuacion de la mRS desde el primer chequeo intermedio. El efecto del tratamiento con policosanol no desaparecio, sino que incluso mejoro despues de seis meses de tratamiento. El numero de pacientes que alcanzaron valores de la mRS <= 1 fue mayor en el grupo de policosanol + aspirina (80,3%) que en el de placebo + aspirina (8,5%). Dos pacientes causaron baja del estudio y cuatro (dos de cada grupo) refirieron efectos adversos leves. Conclusiones. El tratamiento durante seis meses con policosanol + aspirina a pacientes hipertensos que habian sufrido un ictus isquemico no cardioembolico demostro ser mas efectivo que el tratamiento con placebo + aspirina en su recuperacion funcional.
