Objectives: To evaluate the results of the comprehensive geriatric assessment (CGA) before allogeneic hematopoietic stem cell (HSCT) transplantation in patients aged 60 years and over. Methods: We evaluated all consecutive patients undergoing CGA before HSCT between September 2011 and July 2018 in a private hospital in Brazil. We also evaluated the Hematopoietic Cell Transplantation-Specific Comorbidity Index (HCT-SCI) and the Disease Risk Index (DRI). Results: During the study period, 61 patients were referred for transplant evaluation. After exclusions, we analyzed 40 patients, with a mean age of 67.6 years (60-76). The CGA detected vulnerability and frailty in 43% and 18.9% respectively according to the Fried Frailty Phenotype score; limitations across the domain of function and disability with handgrip test alterations in 65.8%. However, 36 (90%) were independent for instrumental activities of daily living (IADL). Cognitive and depression domain have shown abnormal with the clock test in 44.4%, and loss of memory complains in 37.5%. But the mini-mental test was normal in 89%. Geriatric Depression Scale (GDS) was normal in 82.5%. 30% were considered at risk for malnutrition. Half of the patients (50%) had a high Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI) score. 32.5% needed ICU admission. The overall survival and non-relapse mortality at 2 years were 41.8% and 38.7% respectively. Conclusion: The CGA was feasible in detecting the patients' vulnerabilities in our population. More studies, multicentric and with a larger number of patients, are needed to evaluate the role of CGA in this context of allo-HCT in our population.

Objective: To evaluate the effect of waiting time (WT) to radiotherapy (RT) on overall survival (OS) of glioblastoma (GBM) patients as a reliable prognostic variable in Brazil, a scenario of medical disparities. Method: Retrospective study of 115 GBM patients from two different health-care institutions (one public and one private) in Brazil who underwent post-operative RT. Results: Median WT to RT was 6 weeks (range, 1.3-17.6). The median OS for WT # 6 weeks was 13.5 months (95%CI , 9.1-17.9) and for WT . 6 weeks was 14.2 months (95%CI, 11.2-17.2) (HR 1.165, 95%CI 0.770-1.762; p = 0.470). In the multivariate analysis, the variables associated with survival were KPS (p , 0.001), extent of resection (p = 0.009) and the adjuvant treatment (p = 0.001). The KPS interacted with WT to RT (HR 0.128, 95%CI 0.034-0.476; p = 0.002), showing that the benefit of KPS on OS depends on the WT to RT. Conclusion: No prognostic impact of WT to RT could be detected on the OS. Although there are no data to ensure that delays to RT are tolerable, we may reassure patients that the time-length to initiate treatment does not seem to influence the control of the disease, particularly in face of other prognostic factors.Keywords: glioblastoma, radiotherapy, waiting time, delay, prognosis, survival. RESUMOObjetivo: Avaliar o efeito do tempo de espera (TE) até radioterapia na sobrevida global de pacientes com glioblastoma como um fator prognóstico confiável. Método: Estudo retrospectivo de 115 pacientes com glioblastoma, que foram submetidos à radioterapia pós-operatória, em dois serviços diferentes no Brasil (um público e outro privado). Resultados: Mediana de TE para radioterapia foi de 6 semanas (variação, 1,3-17,6). A mediana de sobrevida para TE # 6 semanas foi de 13,5 meses (IC95%, 9,1-17,9) e para TE . 6 semanas foi de 14,2 meses (IC95%, 11,2-17,2) (HR 1,165, 0,762; p = 0,470). Na análise multivariada, as variáveis associadas à sobrevida foram perfomance status (p , 0,001), extensão da ressecção (p = 0,009) e tratamento adjuvante (p = 0,001). Conclusão: Não se observou impacto prognóstico para TE até a radioterapia na sobrevida. Diante de outros fatores prognósticos, é possível assegurar de que o espaço de tempo até a radioterapia não parece influenciar o controle da doença.Palavras-chave: glioblastoma, radioterapia, tempo de espera, atraso, prognóstico, sobrevida.

Background Angiogenesis is one of the hallmarks of cancer. This complex mechanism of tumor progression provides tumors cells with essential nutrients. There have been a limited number of investigations of markers of angiogenesis in Glioblastomas (GBMs), and most previous studies have focused on VEGF-A. Recent evidence suggests that there is a complex lymphatic system in central nervous system (CNS), which suggests VEGF-C and VEGF–D as interesting biomarker candidates. This study was designed to evaluate the expressions of VEGF-A, −C, −D and their co-receptors, VEGFR-1, VEGFR-2, and VEGFR-3 by immunohistochemistry (IHC) using a series of GBMs. In addition, we evaluate any putative correlations between IHC expression levels of VEGF and clinical data of patients. Methods Tumor samples of 70 GBM patients (64 isocitrate dehydrogenase-1 wildtype (wtIDH-1) and 6 mutant (mutIDH-1)) were assessed by IHC using tissue microarray platforms for VEGF subunits and their co-receptors. The medical records were reviewed for clinical and therapeutic data. Results All VEGF subunits and receptors were highly expressed in GBMs: 57 out of 62 (91.9%), 53 out of 56 (94.6%) and 55 out of 63 cases (87.3%) showed VEGF-A, VEGF-C and -D imunoexpression, respectively. Interestingly, we had found both nuclear and cytoplasmic localization of VEGF-C staining in GBM tumor cells. The frequency of immunoexpression of VEGF receptors was the following: VEGFR-1, 65 out of 66 cases (98.5%); VEGFR-2, 63 out of 64 cases (98.4%); VEGFR-3, 49 out of 50 cases (90.0%). There were no significant differences in the patient overall survival (OS) related to the VEGF staining. A weak and monotonous correlation was observed between VEGF and its cognate receptors. The pattern of VEGF IHC was found to be similar when GBM mutIDH-1 subtypes were compared to wtIDH-1. Conclusion Both VEGF-C and –D, together with their receptors, were found to be overexpressed in the majority GBMs, and the IHC expression levels did not correlate with OS or IDH status. To understand the significance of the interactions and increased expression of VEGF-C, VEGF-D, VEGFR-2, and VEGFR-3 axis in GBM requires more extensive studies. Also, functional assays using a larger series of GBM is also necessary to better address the biological meaning of nuclear VEGF-C expression in tumor cells.

Despite obvious disparities between the hospitals, the medical assistance scenario was not an independent predictor of survival. However, survival was directly influenced by additional treatment after surgery. Therefore, increasing access to resources in developing countries like Brazil is critical.

The Brazilian Nutritional Consensus in Hematopoietic Stem Cell Transplantation: Elderly was elaborated by nutritionists, nutrologists and hematologists physicians from 15 Brazilians reference centers in hematopoietic stem cell transplantation, in order to emphasize the importancy of nutritional status and the body composition during the treatment, as well as the main characteristics related to patient’s nutritional assessment. Establishing the consensus, we intended to improve and standardize the nutritional therapy during the hematopoietic stem cell transplantation. The Consensus was approved by the Brazilian Society of Bone Marrow Transplantation.

ObjectiveTo describe the clinical characteristics of Latin American patients with metastatic renal cell carcinoma (mRCC) who experienced a progression-free survival (PFS) for at least 15 months following treatment with sunitinib.Patients and methodsIn this retrospective analysis, mRCC patients in two institutions in Latin America received sunitinib at a starting dose of either 50 mg/day for 4 weeks followed by 2 weeks off treatment (Schedule 4/2) in repeated 6-week cycles or sunitinib 37.5 mg on a continuous daily dosing schedule. Clinical characteristics, tolerability, and PFS data were collected.ResultsTwenty-nine patients with long-term clinical benefit from sunitinib were identified between September 2005 and August 2009. Median PFS was 23 months (range: 15–54 months). Two of the 29 patients with prolonged PFS achieved a complete response and additional eleven had a partial response. Most patients were aged <60 years, had good performance status, favorable or intermediate Memorial Sloan Kettering Cancer Center prognostic risk, and disease limited to one or two sites. Dose reduction was necessary in all patients who started sunitinib at 50 mg/day administered on Schedule 4/2. Adverse events leading to dose reduction included grade 3 hand–foot syndrome, mucositis, fatigue, and hypertension. At the time of data cutoff, four patients were still receiving sunitinib treatment.ConclusionExtended PFS can be achieved in Latin American patients with mRCC treated with sunitinib. Although the small sample size and retrospective nature of this evaluation preclude the identification of pretreatment predictive factors contributing to this benefit, the current analysis warrants further investigation using a larger data set in this population.

O aumento da expressão de receptores do fator de crescimento epidérmico (EGFR) está envolvido no estímulo ao crescimento tumoral. Seus inibidores demonstraram eficácia no tratamento de neoplasias de cabeça e pescoço, cólon e pulmão.A inibição do EGFR pode determinar reações cutâneas em mais de 50% dos pacientes. Em geral, são reversíveis, mas, quando graves, limitam o uso da droga. Lesões papulopustulosas em face e tronco são as mais comuns, além de xerose, alterações ungueais e dos pelos. A intensidade da toxicidade cutânea tem relação direta com a resposta antitumoral. Uma abordagem dermatológica adequada é essencial para dar continuidade à terapia contra o câncer de forma satisfatória.
