A Phase II Prospective, Randomized, Double‐Blind , Placebo‐Controlled and Multicenter Clinical Trial to Assess the Safety of 0.005% Estriol Vaginal Gel in Hormone Receptor–Positive Postmenopausal Women With Early Stage Breast Cancer in Treatment With Aromatase Inhibitor in the Adjuvant Setting

Lessons learned: The levels of circulating follicle-stimulating hormone, luteinizing hormone, estriol, estradiol, and estrone remained unchanged after a 12-week treatment with 0.005% estriol vaginal gel in postmenopausal women receiving nonsteroidal aromatase inhibitors for hormone receptor-positive early breast cancer. These results support the safety of 0.005% estriol vaginal gel for the treatment of bothering symptoms of vulvovaginal atrophy in breast cancer survivors. The results provide clinicians with confidence in the use of this product in women who do not experience symptom relief with nonhormonal remedies. Background: Symptoms of vulvovaginal atrophy associated with treatment with nonsteroidal aromatase inhibitors (NSAIs) negatively impact patients' quality of life and may affect adherence to NSAIs. Vaginal estrogens effectively improve these symptoms, although their safe use in breast cancer survivors remains unclear. Methods: Postmenopausal women with hormone receptor-positive early breast cancer receiving NSAI and moderate-to-severe vaginal dryness were randomized to 0.005% estriol vaginal gel or placebo for 12 weeks. Circulating estrogens, follicle-stimulating hormone (FSH), and luteinizing hormone (LH), were analyzed at baseline and at weeks 1, 3, 8, and 12. The primary safety outcome was the variation in serum FSH from baseline to week 12. Results: Sixty-one women (mean age, 59 years) enrolled in the study. Small oscillations were observed in FSH and LH, although they were always maintained within the postmenopausal range. No significant differences were found in the variation of FSH and LH between baseline and week 12 from the physiological variation observed before treatment. Women receiving 0.005% estriol vaginal gel had slightly increased estriol levels at weeks 1 and 3, with a subsequent reduction until normalizing at week 12; estradiol and estrone remained the below limit-of-quantitation in almost all samples. Conclusion: Ultralow-dose 0.005% estriol vaginal gel did not significantly influence estrogens, FSH, and LH levels in women with breast cancer receiving NSAI. A transient negligible absorption of estriol and a nonsignificant variation of FSH after 12 weeks were observed. These findings provide confidence for the safe use of 0.005% estriol vaginal gel in women with breast cancer with an indication for treatment with vaginal estrogens

Enzyme activities in vineyard soils long-term treated with copper-based fungicides

Copper-based fungicides have been applied in vineyard soils for a long time, which has resulted in increasing soil Cu concentration. However, information relating to non-target effects of these fungicides on microorganisms of these soils is scarce. The aim of this study was to determine the potential enzyme activities of vineyard soils in relation to Cu content and evaluate the potential risks of long-term application of Cu-based fungicides. For this purpose, a wide range of soil samples, having different total, exchangeable and bioavailable Cu contents, were collected from six regions of quality wines located in the NW Iberian Peninsula, and the activity of dehydrogenase, b-glucosidase, urease and phosphatase were measured. Overall, the results obtained indicate adverse effects of Cu on dehydrogenase, b-glucosidase and phosphatase activities and an inconsistent effect on urease activity. Threshold Cu concentrations at which changes in the enzyme activities became evident were 150e200 mg total Cu kg 1 and 60e80 mg bioavailable Cu kg-1.Xunta de Galici

Hydroxytyrosol Supplementation Modifies Plasma Levels of Tissue Inhibitor of Metallopeptidase 1 in Women with Breast Cancer

The etiology of breast cancer can be very different. Most antineoplastic drugs are not selective against tumor cells and also affect normal cells, leading to a wide variety of adverse reactions such as the production of free radicals by altering the redox state of the organisms. Therefore, the objective of this study was to elucidate if hydroxytyrosol (HT) (an antioxidant present in extra virgin olive oil) has a chemomodulatory effect when combined with the chemotherapeutic drugs epirubicin and cyclophosphamide followed by taxanes in breast cancer patients. Changes in plasma levels of matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of metalloproteinases 1 (TIMP-1) throughout the chemotherapy treatment were studied. Both molecules are involved in cell proliferation, apoptosis, neoangiogenesis, and metastasis in breast cancer patients. Women with breast cancer were divided into two groups: a group of patients receiving a dietary supplement of HT and a control group of patients receiving placebo. The results showed that the plasma levels of TIMP-1 in the group of patients receiving HT were significantly lower than those levels found in the control group after the epirubicin-cyclophosphamide chemotherapy.This research was funded by Junta de Andalucía, Spain, Servicio Andaluz de Salud: Subvenciones para la financiacion de la Investigación, Desarrollo, e Innovación Biomédica en Ciencias de la Salud en Biomedicina, Grant number PI-0695-2012

Bevacizumab plus preoperative chemotherapy in operable HER2 negative breast cancer: biomarkers and pathologic response

Purpose: The primary aim of this trial was to assess the rate of pathologic complete responses (pCR) of doxorubicin/cyclophosphamide (AC) followed by bevacizumab/docetaxel (BT), as neoadjuvant therapy for breast cancer (BC). Furthermore, the association between biomarkers and the pCR was explored. Methods: Patients with HER-negative operable stage II–III BC ≥2 cm were enrolled. Four cycles of AC (A 60 mg/m2 and C 600 mg/m2, every 3 weeks) followed by 4 cycles of BT (B 15 mg/kg and T 75 mg/m2, every 3 weeks), were planned. A core-biopsy was performed for biological markers assessment. Results: Seventy-two women were included. Forty-three (63 %) patients were hormone receptor-positive. Sixty-four (89 %) completed the planned treatment, and 66 evaluable patients underwent surgery (92 %): a pCR was achieved in 16 of them (24, 95 % CI 15–36 %). pCR was significantly higher in tumors hormone receptor-negative, and in those with Angiotensin II type 1 receptor (AGTR1) protein overexpression. The overall clinical response rate was 86 % (95 % CI 76–93 %), including 42 complete responses. No unexpected toxicities or treatment-related deaths were observed. Conclusion: This regimen showed a remarkable clinical and pathological activity: the suggested relation between pCR and AGTR1 overexpression should be confirmed in larger trials.Financial support for this research was provided by Roche Farma, S.A

Ozone Therapy in the Management of Persistent Radiation-Induced Rectal Bleeding in Prostate Cancer Patients

Introduction. Persistent radiation-induced proctitis and rectal bleeding are debilitating complications with limited therapeutic options. We present our experience with ozone therapy in the management of such refractory rectal bleeding. Methods. Patients (n=12) previously irradiated for prostate cancer with persistent or severe rectal bleeding without response to conventional treatment were enrolled to receive ozone therapy via rectal insufflations and/or topical application of ozonized-oil. Ten (83%) patients had Grade 3 or Grade 4 toxicity. Median follow-up after ozone therapy was 104 months (range: 52–119). Results. Following ozone therapy, the median grade of toxicity improved from 3 to 1 (p<0.001) and the number of endoscopy treatments from 37 to 4 (p=0.032). Hemoglobin levels changed from 11.1 (7–14) g/dL to 13 (10–15) g/dL, before and after ozone therapy, respectively (p=0.008). Ozone therapy was well tolerated and no adverse effects were noted, except soft and temporary flatulence for some hours after each session. Conclusions. Ozone therapy was effective in radiation-induced rectal bleeding in prostate cancer patients without serious adverse events. It proved useful in the management of rectal bleeding and merits further evaluation

Aplicaciones didácticas del cómic. Hacia la configuración de un temario universitario

Desde 2008, Unicómic, a través de las Jornadas de Cómic de la Universidad de Alicante (), dedica una parte de sus sesiones a reflexiones teóricas sobre el cómic, lo que ha dado pie a que se convierta en un referente académico en torno a la narración gráfica. En 2011, con la aparición del Club de Lectura Universitario de Cómic y Álbum Ilustrado (CLUECA), se creó un espacio de encuentro a lo largo de todo el curso para presentar obras fundamentales, tanto del cómic como del álbum ilustrado. En el curso 2012-2013 se realizaron las primeras jornadas Cómic como elemento didáctico (), que en noviembre de 2013 tuvieron la segunda edición () y, en 2015, la tercera (). Con la consolidación de la red en docencia universitaria «Cómic como herramienta didáctica. La narración gráfica en disciplinas académicas y tramos de preparación a la universidad» (código 3283), se configura un espacio de intercambio y de estudio más amplio. Desde su creación, se han defendido distintos TFG y TFM, y se han incorporado aspectos a distintas asignaturas universitarias. En el siguiente trabajo se hace un recorrido por todas estas propuestas como una nueva estrategia metodológica en la formación universitaria para responder a los múltiples cambios a los que se enfrenta nuestro sistema educativo, reivindicando así las posibilidades didácticas del cómic

Polymorphisms within autophagy-related genes influence the risk of developing colorectal cancer: a meta-analysis of four large cohorts

The role of genetic variation in autophagy-related genes in modulating autophagy and cancer is poorly understood. Here, we comprehensively investigated the association of autophagy-related variants with colorectal cancer (CRC) risk and provide new insights about the molecular mechanisms underlying the associations. After meta-analysis of the genome-wide association study (GWAS) data from four independent European cohorts (8006 CRC cases and 7070 controls), two loci, DAPK2 (p = 2.19 × 10−5) and ATG5 (p = 6.28 × 10−4) were associated with the risk of CRC. Mechanistically, the DAPK2rs11631973G allele was associated with IL1 β levels after the stimulation of peripheral blood mononuclear cells (PBMCs) with Staphylococcus aureus (p = 0.002), CD24 + CD38 + CD27 + IgM + B cell levels in blood (p = 0.0038) and serum levels of en-RAGE (p = 0.0068). ATG5rs546456T allele was associated with TNF α and IL1 β levels after the stimulation of PBMCs with LPS (p = 0.0088 and p = 0.0076, respectively), CD14+CD16− cell levels in blood (p = 0.0068) and serum levels of CCL19 and cortisol (p = 0.0052 and p = 0.0074, respectively). Interestingly, no association with autophagy flux was observed. These results suggested an effect of the DAPK2 and ATG5 loci in the pathogenesis of CRC, likely through the modulation of host immune responses.This work was partially supported by grants from the Instituto de Salud Carlos III (Madrid, Spain; PI12/02688 and PI17/02256).

Trajectories of alcohol consumption during life and the risk of developing breast cancer

Background Whether there are lifetime points of greater sensitivity to the deleterious effects of alcohol intake on the breasts remains inconclusive. Objective To compare the influence of distinctive trajectories of alcohol consumption throughout a woman's life on development of breast cancer (BC). Methods 1278 confirmed invasive BC cases and matched (by age and residence) controls from the Epi-GEICAM study (Spain) were used. The novel group-based trajectory modelling was used to identify different alcohol consumption trajectories throughout women's lifetime. Results Four alcohol trajectories were identified. The first comprised women (45%) with low alcohol consumption (= 15 g/day), never having a low alcohol consumption. Comparing with the first trajectory, the fourth doubled BC risk (OR 2.19; 95% CI 1.27, 3.77), followed by the third (OR 1.44; 0.96, 2.16) and ultimately by the second trajectory (OR 1.17; 0.86, 1.58). The magnitude of BC risk was greater in postmenopausal women, especially in those with underweight or normal weight. When alcohol consumption was independently examined at each life stage, >= 15 g/day of alcohol consumption in adolescence was strongly associated with BC risk followed by consumption in adulthood. Conclusions The greater the alcohol consumption accumulated throughout life, the greater the risk of BC, especially in postmenopausal women. Alcohol consumption during adolescence may particularly influence BC risk.This study was funded by the Fundacion Cientifica Asociacion Espanola Contra el Cancer (AECC) (Scientific Foundation of the Spanish Association against Cancer 2006 & 2016) (Marina Pollan), Sociedad Espanola de Oncologia Medica (SEOM) (Spanish Society of Medical Oncology) (Miguel Martin), Scholarship 'Contrato de atraccion de talento' from Community of Madrid (Carolina Donat-Vargas), Fundacion Cerveza y Salud 2005 (Beer and Health Foundation 2005) (Miguel Martin) and Federacion de Asociaciones de Mujeres con Cancer de Mama (FECMA) (Spanish Federation of Associations of Women with Breast Cancer) (Miguel Martin, Marina Pollan)

Quality of life with palbociclib plus fulvestrant versus placebo plus fulvestrant in postmenopausal women with endocrine-sensitive hormone receptor-positive and HER2-negative advanced breast cancer : patient-reported outcomes from the FLIPPER trial

In the FLIPPER trial, palbociclib/fulvestrant significantly improved progression-free survival (PFS) compared with placebo/fulvestrant in postmenopausal women with HR+/HER2− advanced breast cancer (ABC). We assessed health-related quality of life (QoL) using patient-reported outcomes (PROs). In this phase II double-blinded study, PROs were assessed at baseline after every three cycles and at the end of the treatment using the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR23. Time to deterioration (TTD) in global health status (GHS)/QoL was defined as a decrease of ⩾10 points. Changes from baseline (CFB) and TTD were analysed using linear mixed-effect and Cox regression models, respectively. Of the 189 randomised (1:1) patients, 178 (94%) completed ⩾1 post-baseline assessment; 50% received ⩾22 cycles of study treatment, with a questionnaire compliance >90%. Mean baseline scores were comparable between arms. GHS/QoL scores were maintained throughout the palbociclib/fulvestrant treatment. CFB showed significant differences for GHS/QoL, appetite loss, constipation and systemic therapy side effect scores favouring placebo/fulvestrant. TTD in GHS/QoL was delayed in placebo/fulvestrant versus palbociclib/fulvestrant [30.3 versus 11.1 months; adjusted hazard ratio (aHR): 1.57, 95% CI: 1.03-2.39, p = 0.036]; this difference was not significant in patients with progressive disease (aHR: 1.2, 95% CI: 0.6-2.2, p = 0.658). No statistically significant differences in TTD were found for the other QLQ-C30 and QLQ-BR23 scales. Although TTD in GHS/QoL was prolonged with placebo/fulvestrant, no differences were observed on other functional or symptom scales. This finding and the improvement in PFS support the combination of palbociclib/fulvestrant as a beneficial therapeutic option for HR+/HER2− ABC.
