RESUMEN

Abstract Background With the COVID-19 pandemic, the clinical practice of physicians who work in the head and neck field in Brazil dropped dramatically. The sustained impact of the pandemic is not known. Methods An anonymous online survey was distributed to Brazilian otolaryngologists, head and neck surgeons, medical and radiation oncologists, asking about their clinical practice in the third to fourth months of the pandemic. Results The survey was completed by 446 specialists. About 40 % reported reduction of more than 75 % in outpatient care. A reduction of 90 % to 100 % in airway endoscopies was reported by 50 % of the responders, and the same rate of reduction regarding surgeries (pediatric or nasosinusal) was reported by 80 % of them. Family income decreased by 50 %, and the psychological burden on physicians was considerable. The availability of personal protective equipment and safety precautions were limited, especially in the public sector. Conclusion COVID-19 is still impacting the head and neck field, and safety concerns may hinder the prompt resumption of elective care.

RESUMEN

ABSTRACT Objective: Adjuvant chemotherapy (AC) improves survival of patients with resected non-small cell lung cancer (NSCLC). However, the cisplatin-vinorelbine regimen has been associated with a significant risk of clinically relevant toxicity. We sought to evaluate the effectiveness, safety, and feasibility of AC for NSCLC patients in a real-world setting. Methods: This was a single-center, retrospective cohort study of patients with stage I-III NSCLC undergoing surgery with curative intent between 2009 and 2018. AC was administered at the discretion of physicians. The patients were divided into two groups: AC group and no AC (control) group. Study outcomes included overall survival (OS) and recurrence-free survival (RFS), as well as the safety profile and feasibility of the cisplatin-vinorelbine regimen in a real-world setting. Results: The study involved 231 patients, 80 of whom received AC. Of those, 55 patients received the cisplatin-vinorelbine regimen. Survival analyses stratified by tumor stage showed that patients with stage II NSCLC in the AC group had better RFS (p = 0.036) and OS (p = 0.017) than did those in the no AC group. Among patients with stage III NSCLC in the AC group, RFS was better (p < 0.001) and there was a trend toward improved OS (p = 0.060) in comparison with controls. Of those who received the cisplatin-vinorelbine regimen, 29% had grade 3-4 febrile neutropenia, and 9% died of toxicity. Conclusions: These results support the benefit of AC for NSCLC patients in a real-world setting. However, because the cisplatin-vinorelbine regimen was associated with alarming rates of toxicity, more effective and less toxic alternatives should be investigated.


RESUMO Objetivo: A quimioterapia adjuvante melhora a sobrevida de pacientes com câncer pulmonar de células não pequenas (CPCNP) ressecado. No entanto, o esquema cisplatina-vinorelbina está relacionado com risco significativo de toxicidade clinicamente relevante. Nosso objetivo foi avaliar a eficácia, segurança e viabilidade da quimioterapia adjuvante para pacientes com CPCNP em um cenário de mundo real. Métodos: Estudo retrospectivo de coorte realizado em um único centro com pacientes com CPCNP em estágio I-III submetidos a cirurgia com intuito curativo entre 2009 e 2018. A quimioterapia adjuvante foi administrada a critério dos médicos. Os pacientes foram divididos em dois grupos: quimioterapia adjuvante e sem quimioterapia adjuvante (grupo controle). Os desfechos estudados foram sobrevida global (SG) e sobrevida livre de recidiva (SLR), bem como o perfil de segurança e viabilidade do esquema cisplatina-vinorelbina em um cenário de mundo real. Resultados: O estudo envolveu 231 pacientes, 80 dos quais receberam quimioterapia adjuvante. Destes, 55 receberam o esquema cisplatina-vinorelbina. As análises de sobrevida estratificadas pelo estágio do tumor mostraram que os pacientes com CPCNP em estágio II que receberam quimioterapia adjuvante apresentaram melhor SLR (p = 0,036) e SG (p = 0,017) do que os do grupo controle. Entre os pacientes com CPCNP em estágio III que receberam quimioterapia adjuvante, a SLR foi melhor (p < 0,001) e houve uma tendência a melhor SG do que no grupo controle (p = 0,060). Dos que receberam o esquema cisplatina-vinorelbina, 29% apresentaram neutropenia febril de grau 3-4, e 9% morreram em virtude de toxicidade. Conclusões: Os resultados confirmam o efeito benéfico da quimioterapia adjuvante em pacientes com CPCNP em um contexto real. No entanto, o esquema cisplatina-vinorelbina relacionou-se com taxas alarmantes de toxicidade e alternativas mais eficazes e menos tóxicas devem ser investigadas.

RESUMEN

OBJECTIVES: To evaluate the molecular testing and treatment patterns in a retrospective cohort of newly diagnosed treatment-naïve patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC). METHODS: This is an observational retrospective cohort study conducted across 10 cancer centers in Brazil. Treatment-naïve patients with locally advanced or metastatic NSCLC were enrolled from January to December 2014. The following data were collected from the medical records of patients from diagnosis until the last record (death, loss to follow-up, or the end of the maximum follow-up period): demographics; medical history; smoking status; disease characteristics; previous treatments; and molecular testing patterns and results. The overall survival (OS) was also estimated. Results: A total of 391 patients from 8 different Brazilian states were included, with a median age of 64.1 years (23.7-98.7), with most patients being males (60.1%). The smoking status of 74.2% of patients was a 'former' or 'current smoker'. Stage IV NSCLC at diagnosis was observed in 82.4% of patients, with 269 of them (68.8%) presenting adenocarcinoma (ADC). Among the stage IV ADC patients, 54.0% were referred for molecular testing. Among the patients with an available epidermal growth factor receptor (EGFR) mutation status, 31 (24.0%) were EGFR-positive. The first-line treatment was a platinum-based chemotherapy for 98 patients (25.1%), while non-platinum-based regimens were used in 54 patients (13.8%). OS data were available for 370 patients, with a median OS of 10.8 months. Never smokers had a significantly higher median OS versus current or former smokers (14.6 versus 9.1 months; log-rank p=0.003). Among the patients for whom molecular testing data were available, those with EGFR-positive results had a longer median OS (34.6 versus 12.8 months; log-rank p=0.003). Conclusion: Our findings provide relevant information for prescribers and policy decision-makers by highlighting the unmet needs of patients and the importance of molecular testing in newly diagnosed locally advanced or metastatic lung adenocarcinoma. We also highlight the respective EGFR-tyrosine kinase inhibitor treatment when the result is positive and the areas in which further efforts are required to grant access to effective treatment.

RESUMEN

Summary Total thyroidectomy, radioiodine (RAI) therapy, and TSH suppression are the mainstay treatment for differentiated thyroid carcinomas (DTCs). Treatments for metastatic disease include surgery, external-beam radiotherapy, RAI, and kinase inhibitors for progressive iodine-refractory disease. Unresectable locoregional disease remains a challenge, as standard therapy with RAI becomes unfeasible. We report a case of a young patient who presented with unresectable papillary thyroid carcinoma (PTC), and treatment with sorafenib allowed total thyroidectomy and RAI therapy. A 20-year-old male presented with severe respiratory distress due to an enlarging cervical mass. Imaging studies revealed an enlarged multinodular thyroid gland, extensive cervical adenopathy, severe tracheal stenosis, and pulmonary micronodules. He required an urgent surgical intervention and underwent tracheostomy and partial left neck dissection, as the disease was deemed unresectable; pathology revealed PTC. Treatment with sorafenib was initiated, resulting in significant tumor reduction allowing near total thyroidectomy and bilateral neck dissection. Postoperatively, the patient underwent radiotherapy for residual tracheal lesion, followed by RAI therapy for avid cervical and pulmonary disease. The patient's disease remains stable 4 years after diagnosis. Sorafenib has been approved for progressive RAI-refractory metastatic DTCs. In this case report, we describe a patient with locally advanced PTC in whom treatment with sorafenib provided sufficient tumor reduction to allow thyroidectomy and RAI therapy, suggesting a potential role of sorafenib as an induction therapy of unresectable DTC.

RESUMEN

ABSTRACT Lung cancer is one of the most incident types of cancer and a leading cause of cancer mortality in Brazil. We reviewed the current status of lung cancer by searching relevant data on prevention, diagnosis, and treatment in the country. This review highlights several issues that need to be addressed, including smoking control, patient lack of awareness, late diagnosis, and disparities in the access to cancer health care facilities in Brazil. We propose strategies to help overcome these limitations and challenge health care providers, as well as the society and governmental representatives, to work together and to take a step forward in fighting lung cancer.


RESUMO O câncer de pulmão é um dos tipos de câncer com maior incidência e uma das principais causas de mortalidade por câncer no Brasil. Revisamos a situação atual do câncer de pulmão por meio de pesquisa de dados relevantes a respeito de prevenção, diagnóstico e tratamento no país. Esta revisão mostra várias questões que precisam de atenção, tais como controle do tabagismo, educação dos pacientes, desconhecimento por parte dos pacientes, diagnóstico tardio e desigualdade de acesso ao tratamento de câncer no Brasil. Propomos estratégias para ajudar a superar essas limitações e desafiamos os profissionais de saúde, a sociedade e os representantes do governo a trabalhar em conjunto e dar um passo à frente na luta contra o câncer de pulmão.
