RESUMEN

BACKGROUND: Premenopausal, high-risk, hormone receptor-positive breast cancer patients are often treated with ovarian suppression in combination with aromatase inhibitors (AI). This combination has important adverse effects, particularly in sexual function, such as vaginal dryness and loss of libido. There is no effective therapy for reduced sexual function in this setting. Our study aimed to determine the efficacy and safety, particularly regarding sexual function, of a low-dose, topical testosterone gel administration. METHODS: This is a pilot, single-center study, designed to evaluate the efficacy of topical testosterone gel (3 mg/day) in improving sexual function in 29 premenopausal patients on ovarian suppression in combination with an AI. The primary safety endpoint was to assess serum estradiol elevation. The primary efficacy endpoint was sexual function improvement, assessed by the Female Sexual Function Index questionnaire. RESULTS: We report the results on 29 patients. Twenty-two patients (75%) completed the 3-month treatment, and seven discontinued treatment before completion, mostly due to logistical difficulties related to the COVID-19 pandemic. All patients maintained the value of baseline mass spectrometry assay for estradiol of less than 2.7 pg/mL during the undertaken measurements. We observed a significant improvement in Female Sexual Function Index measures over the visits, with an increase from a mean of 11.7 at baseline to 19.1 in the third month (p < 0.001), with the greatest improvement observed between the second and third months. CONCLUSIONS: Our findings suggest that topical testosterone seems to be safe and may be effective in improving sexual function in patients on ovarian suppression and AI. TRIAL REGISTRATION: The project was submitted and approved through the hospital's SGPP platform in 11/26/2019 (Project No. SGPP 393819) and CAAE (Research Ethics Committee) (CAAE No 25609719.5.0000.007).

RESUMEN

Inactivation of the cyclin-dependent kinase inhibitor 2A (CDKN2A) gene is considerably more frequent in squamous cell lung cancer (SqCLC) than in other subtypes of lung cancer and may be a promising target for this histology. Here, we present the course of diagnosis and treatment of a patient with advanced SqCLC, harboring not only CDKN2A mutation but also PIK3CA amplification, Tumor Mutational Burden-High (>10 mutations/megabase), and a Tumor Proportion Score of 80%. After disease progression on multiple lines of chemotherapy and immunotherapy, he responded favorably to treatment with the CDK4/6i Abemaciclib and later achieved a durable partial response to immunotherapy rechallenge with a combination of anti-PD-1 and anti-CTLA-4, nivolumab, and ipilimumab.

RESUMEN

Objetivo: Traduzir e realizar a adaptação transcultural para a Língua Portuguesa do escore de toxicidade de Hurria, instrumento utilizado para avaliação de toxicidade à quimioterapia em idosos. Métodos: Realizada a tradução e adaptação transcultural do escore, seguindo a técnica proposta por Guilemin de tradução/retrotradução. Resultados: A tradução foi realizada por dois brasileiros fluentes em inglês, sendo um médico e um tradutor profissional. Sequencialmente, realizou-se a retrotradução do escore por dois profissionais independentes ao estudo, ligados a um serviço especializado de tradução linguística. Finalmente, um comitê formado por especialistas em Oncologia, Geriatria e Hematologia checou a consistência da tradução/retrotradução, chegando a um modelo final na Língua Portuguesa. Posteriormente, esse modelo sofreu avaliação prática em uma amostra de prontuários de um ambulatório de Oncogeriatria, com versão em português do instrumento atingindo alto grau de confiabilidade pelo teste estatístico de Kappa. Conclusão: A versão final do escore de toxicidade de Hurria em português mostrou-se clara, simples e de rápida aplicação, estando adequada para o uso na prática clínica.


Objective: To describe the translation and transcultural adaptation of Hurria's chemotherapy toxicity score, a prediction tool to estimate chemotherapy toxicity in the elderly. Methods: The original English version of the score was translated to Portuguese using the forward and backward translation technique, as described by Guilemin. Results: The translation was performed by two Brazilians (a physician and a professional translator), both fluent in English. Two professionals from a specialized linguistic service, not related to the study, then carried out the backward translation. Finally, a medical committee composed of oncologists, geriatricians, and hematologists discussed the consistency of the score, choosing a final version of the instrument in Portuguese. This version was piloted-tested in medical charts in an Oncogeriatric service, with high reliability as tested by Kappa statistic test. Conclusion: The final version of Hurria's chemotherapy toxicity score in Portuguese proved to be an easy, clear, and quick tool, suitable for use in clinical practice.

RESUMEN

OBJECTIVE: To analyze how elderly patients with glioblastoma are managed in Brazil. MATERIAL AND METHODS: We identified 30 patients aged ≥ 65 years treated between 2003 and 2011 at Albert Einstein Hospital in Sao Paulo. We retrospectively reviewed medical records to obtain data on clinical variables, treatment and outcomes. Overall survival (OS) was evaluated using Kaplan-Meier methods and compared using a Wilcoxon log-rank test. RESULTS: The median age was 73 years. The majority of patients (73.2%) underwent surgical intervention. Following surgery, 80% received radiotherapy (RT), and of those, 79.2% were treated with concurrent temozolomide (TMZ). The median progression free survival and OS were 5 and 10.6 months, respectively. Patients with a KPS ≥ 70 had a median OS of 16.2 months, compared to 6.4 months for those with a KPS <70 (p=0.032). For those patients in whom biopsy only was performed, the median OS was 5.3 months, as compared to 7.8 months for those who underwent partial resection and 18.6 months for those treated with gross total resection (p=0.021). A longer survival was found among patients who received RT versus those who did not (11 months vs. 1 month, p=0.003), as well as for those treated with chemoradiation (13.6 months vs. 6.4 months, p<0.0001). CONCLUSIONS: This study brings new information about the management of elderly patients with glioblastoma in Brazil. Our data may suggest that elderly patients who undergo cytoreductive surgery and adjuvant RT with concurrent TMZ can do better than those with less aggressive treatment.

RESUMEN

Treating elderly cancer patients is a challenge for oncologists, especially considering the several therapeutic modalities in glioblastoma. Extensive tumor resection offers the best chance of local control. Adequate radiotherapy should always be given to elderly patients if they have undergone gross total resection and have maintained a good performance status. Rather than being ruled out, chemotherapy should be considered, and temozolomide is the chosen drug. A comprehensive geriatric assessment is a valuable tool to help guiding treatment decisions in elderly patients with glioblastoma.


O tratamento de idosos com câncer é um desafio para a prática oncológica, especialmente no que se refere à terapêutica multimodal do glioblastoma. Nessa população, a ressecção ampla do tumor oferece a melhor chance de controle local e, naqueles pacientes que mantenham um bom performance status, a radioterapia complementar deve sempre ser levada em consideração. A quimioterapia também tem um papel no tratamento, sendo a temozolomida a droga de eleição. Frente à heterogeneidade desses pacientes, uma avaliação geriátrica ampla é um instrumento valioso no auxílio da decisão terapêutica em idosos com glioblastoma.
