RESUMO

BACKGROUND: This study retrospectively analyzed the risk factors for oral mucositis (OM) during cetuximab treatment. MATERIAL AND METHODS: We screened patients using cetuximab and retrospectively evaluated the presence of OM based on medical records. We collected information from 2 years of evaluations. Patient medical records were reviewed to obtain data on chemotherapy cycle and dose, sex, age, primary tumor, TNM stage, and head and neck radiotherapy (HNR) history. The X2 test and multinomial logistic regression were used for statistical analysis (SPSS 20.0, p < 0.05). RESULTS: Among 1831 patients, OM was showed in 750 in any grade (41%), during cetuximab treatment. Most patients were female (n=944, 51.6%), <70years-old (n=1149, 62.8%), had larynx cancer (n=789, 43.1%) in T4 (n=579, 47.7%), N0 (n=509, 52.6%) stages. Primary tumor surgery was performed in 1476 (80.6%) patients, radiotherapy in 606 (33.1%) patients and cetuximab protocols most used involved up to four cycles (n=1072, 58.5%) of <400mg (n=996, 54.4%) cetuximab doses. Female (OR [odds ratio] = 2.17, CI95% = 1.26-3.75), >70 years-old patients (OR = 16.02, CI95% = 11.99-21.41), with HHNR (OR = 1.84, 1.41-2.40), treated with >4 cycles (OR = 1.52, CI95% = 1.16-2.01) and high doses of cetuximab (OR = 3.80, CI95% = 2.52-5.71) are the greatest risk factors for OM. CONCLUSIONS: Since the clinical benefit of cetuximab in the treatment of older patients is limited and there is a high OM, especially in women with head and neck treated with radiotherapy, high doses and a high number of cetuximab cycles must be administered with caution.

RESUMO

Antecedentes y objetivo: La pérdida de peso es un motivo frecuente de consulta que abarca múltiples posibilidades diagnósticas. El objetivo de este trabajo es estudiar las características de los pacientes que acuden a consulta por pérdida de peso y establecer la relación de esta con las neoplasias. Método: Se analizaron datos demográficos, pérdida de peso cuantificada, sintomatología acompañante y diagnóstico de los pacientes que acuden a consulta por este motivo, durante el año 2015. Resultados: Se incluyeron 226 pacientes, de los cuales el 44,2% presentaba una pérdida de peso≥5% en los 6 meses previos. El diagnóstico más frecuente en este grupo fueron las neoplasias, mientras que en el resto de los pacientes fueron las enfermedades digestivas. Se establece relación entre una pérdida de peso≥5% y la presencia de neoplasias. Conclusión: Una pérdida de peso superior al 5% en los 6 meses previos se asocia con la presencia de enfermedades neoplásicas, lo que exige un estudio diagnóstico exhaustivo


Background and objective: Unintentional weight loss is frequent reason to visit a doctor and it has multiple diagnostic possibilities. The objective of this study is to examine the background of the patients who seek consultation for weight loss and to establish the relationship between weight loss and neoplasia. Method: An analysis was performed on the demographic data, quantified weight loss, accompanying symptomatology, and diagnosis of patients who sought medical advice for unintentional weight loss during the year 2015. Results: A total of 226 patients were included, of whom 44.2% of them had an intentional weight loss ≥ 5% in 6 months. The most frequent diagnosis in this group was a neoplasia, whereas in the rest of patients the most common diagnosis was a gastrointestinal disease. In light of this study we can conclude that there is a relationship between unintentional weight loss≥5% and the presence of neoplasia. Conclusion: An unintentional weight loss greater than 5% in the previous 6 months is associated with the presence of neoplastic diseases, and therefore requires further diagnostic study

RESUMO

We have measured quasiinstantaneous transverse patterns in a broad aperture laser. Nonordered patterns yielding to boundary determined regular structures in progressive time-integrated recording are observed. The linear analysis and numerical integration of the full Maxwell-Bloch equations allow us to interpret the features of the experiment. We show that this system being far from threshold cannot be fully understood with a perturbative model.
