Abstract
Although lung cancer (LC) is one of the most common and lethal tumors, only 15% of patients are diagnosed at an early stage. Smoking is still responsible for more than 85% of cases. Lung cancer screening (LCS) with low-dose CT (LDCT) reduces LC-related mortality by 20%, and that reduction reaches 38% when LCS by LDCT is combined with smoking cessation. In the last decade, a number of countries have adopted population-based LCS as a public health recommendation. Albeit still incipient, discussion on this topic in Brazil is becoming increasingly broad and necessary. With the aim of increasing knowledge and stimulating debate on LCS, the Brazilian Society of Thoracic Surgery, the Brazilian Thoracic Association, and the Brazilian College of Radiology and Diagnostic Imaging convened a panel of experts to prepare recommendations for LCS in Brazil. The recommendations presented here were based on a narrative review of the literature, with an emphasis on large population-based studies, systematic reviews, and the recommendations of international guidelines, and were developed after extensive discussion by the panel of experts. The following topics were reviewed: reasons for screening; general considerations about smoking; epidemiology of LC; eligibility criteria; incidental findings; granulomatous lesions; probabilistic models; minimum requirements for LDCT; volumetric acquisition; risks of screening; minimum structure and role of the multidisciplinary team; practice according to the Lung CT Screening Reporting and Data System; costs versus benefits of screening; and future perspectives for LCS.

ACTA ACUST UNITED AC 2020; 47:e20190426. [PMID: 33331462 PMCID: PMC7889323 DOI: 10.36416/1806-3756/e20190426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2010] [Accepted: 06/07/2020] [Indexed: 11/29/2022]
Abstract
Objective: To evaluate the evolution of clinical and epidemiological data, as well as data related to diagnosis, staging, treatment, and survival, among patients undergoing curative surgery for lung cancer at a tertiary referral center in the city of São Paulo, Brazil. Methods: This was a retrospective study of cases in the International Association for the Study of Lung Cancer database. We selected only cases of patients undergoing curative surgery between January of 2011 and April of 2018. We determined overall and disease-free survival at 36 months and compared the data between two periods (2011-2014 and 2015-2018). Results: Comparing the two periods (N = 437 cases), we observed trends toward increases in the number of female patients, as well as in the proportions of former smokers (44.09% vs. 53.59%), of patients diagnosed with adenocarcinoma (52.21% vs. 59.72%), and of patients diagnosed at an earlier pathological stage, together with a decrease in 30-day mortality (4.05% vs. 2.39%). There were significant increases in the proportions of cases diagnosed at an earlier clinical stage (p = 0.002) or incidentally (p = 0.003). Although lobectomy was the main surgical technique employed, there was a proportional increase in segmentectomies (2.67% vs. 7.11%; p = 0.026). Overall and disease-free survival rates were 79.4% (95% CI: 74.0-83.9%) and 75.1% (95% CI: 69.1-80.1%), respectively. The difference in overall survival between the periods lost statistical significance when adjusted for pathological stage, the only factor that affected survival (log-rank: p = 0.038 to p = 0.079). Conclusions: The clinical and epidemiological evolution presented in this study corroborates global trends. The decrease in 30-day mortality was probably due to better patient selection and improved surgical techniques.

Abstract
Objective Lung cancer is the leading cause of death by cancer, and the bones are one of the most common sites of metastasis from this condition. This study aimed to evaluate the influence of lung carcinoma histology on the frequency of bone metastases. Methods This retrospective study evaluated the medical records of 407 patients diagnosed with lung cancer between 2003 and 2012. The prevalence of bone metastases and their association with histological subtypes were evaluated using chi-squared tests, odds ratios (ORs) and 95% confidence intervals (CIs). The overall survival was evaluated using the Kaplan-Meier method. Results The prevalence of bone metastases was 28.2% ( n = 115), and the spine was the most frequently affected site (98 metastases; 32.1%). Adenocarcinoma was the most common histological subtype of lung carcinoma (46.7%), and it was significantly more frequent among patients with bone metastases (58.3% versus 42.1%; p = 0.003; OR = 1.92; 95% CI: 1.29-2.97). Squamous cell carcinoma was significantly less frequent among patients with bone metastases (13.0% versus 29.8%; p = 0.0004; OR = 0.35; 95% CI: 0.19-0.64). The median survival time after the first bone metastasis diagnosis was 4 months. Conclusion Adenocarcinoma was the most common histological subtype of lung carcinoma, and it was significantly associated with a higher risk of developing bone metastases.

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.

Abstract
Lung cancer persists throughout the world as a major cause of death. In 2014, data from the Brazilian National Cancer Institute (INCA) estimated 16.400 new cases of lung cancer among men (second most common) and 10.930 new cases among women (fourth most common). These data are consistent for all Brazilian regions and reflect the trends of cancer in the country over the last decade. Brazil is a continental country, the largest in Latin America and fifth in the world, with an estimated population of >200 million. Although the discrepancy in the national income between rich and poor has diminished in the last 2 decades, it is still huge. More than 75% of the Brazilian population do not have private health insurance and rely on the national health care system, where differences in standard of cancer care are evident. It is possible to point out differences from the recommendations of international guidelines in every step of the lung cancer care, from the diagnosis to the treatment of advanced disease. This review aims to describe and recognize these differences as a way to offer a real discussion for future modifications and action points toward delivery of better oncology care in our country.

Abstract
OBJECTIVES Regarding the fatality rates stemming from various existing forms of cancers worldwide, lung cancer (LC) is ranked as the main cause of death amongst those who suffer from cancer. Although the epidemiological, clinical, and histological profile of patients with this type of cancer is largely unknown, Brazil has made tremendous efforts to generate data for supporting healthcare policies concerning lung cancer. Taking these factors into account, this study aims to analyse the epidemiological, clinical, and histological profiles of patients with non-small-cell lung cancer (NSCLC) in Brazil. MATERIAL AND METHODS For this study, a cross-sectional epidemiological study was conducted to nationally analyse patient's data within the cancer hospital registries found in the National Cancer Institute (INCA) and the São Paulo Cancer Foundation (FOSP) between 2000 and 2011. RESULTS A total of 35,018 patients diagnosed with NSCLC in Brazil between 2000 and 2011 were analysed. The analysis demonstrated the occurrence of an epidemiological shift, related to the most prevalent histological type of NSCLC in the study population from 2003. The shift resulted in a higher percentage of adenocarcinoma (43.3%) over squamous cell carcinoma (36.5%). Additionally, there was a significant increase in both the number of cases of LC in women and in the rates of patients diagnosed with metastatic disease. CONCLUSION The use of filtered cigarettes since the 60's and the increase in the number of LC cases in women, were one of the causes for the switch in the histological profile of NSCLC in Brazil. Consequently, adenocarcinoma is now the predominant type of cancer detected. Late diagnosis is a hallmark sign.

Abstract
Cancer is now the second leading cause of death in Brazil (after cardiovascular diseases) and a public health problem, with around 500,000 new cases in 2012. Excluding nonmelanoma skin cancer, lung cancer is the second most incident cancer type in men, with 17,210 expected new cases. In women, it is the fifth most incident cancer, with 10,110 expected new cases. The estimated age-adjusted lung cancer mortality rate is about 13/100,000 for men and 5.4/100,000 for women. Lung cancer rates in men increased until the early 1990s and decreased thereafter, especially in the younger population. In contrast, a steady upward trend was observed for women. The positive effects in men were probably due to the successful anti-tobacco campaign conducted in Brazil over the last decades, which led to a decrease in the adult smoking population, from 32% in the early 1980s to 17% in the 2000s. Although the Brazilian National Cancer Institute is strongly committed to providing excellence in multimodality care to cancer patients, limitations in availability and adequate geographic distribution of specialists and well-equipped cancer centers are evident. Major disparities in patient access to proper staging and state-of-the-art treatment still exist. Considering that World Health Organization (WHO) officials estimate that cancer will become the number one cause of death in most developing countries, including Brazil, in the next decades, it is highly recommended for government authorities to implement firm actions to face this tremendous challenge.

Abstract
OBJETIVO: Analisar a tomografia computadorizada e a broncoscopia no diagnóstico do câncer pulmonar e verificar a eficácia destas técnicas perante a presença desta doença. Os parâmetros idade, gênero, hábitos tabágicos, tipos histológicos, estadiamento e terapêutica foram, igualmente, analisados. MATERIAIS E MÉTODOS: Foram analisados 70 pacientes do Serviço de Pneumologia do Hospital Distrital da Figueira da Foz, Coimbra, Portugal, que realizaram ambas as técnicas em estudo, tendo-se confirmado ou não a presença de câncer pulmonar. RESULTADOS: Diagnosticaram-se 37 tumores pulmonares, 23 casos no gênero masculino e 14 no feminino. Histologicamente, 40,54% eram adenocarcinomas, seguido do carcinoma escamoso (32,43% dos casos) e do carcinoma de pequenas células (18,92%). O estadiamento mostrou 6,70% no estádio IB, 23,30% no estádio IIIA comparativamente ao IIIB com 36,70%, encontrando-se 33,30% dos doentes no estádio IV. A quimioterapia isolada foi efetuada em 75,7% dos doentes. A sensibilidade da broncoscopia foi de 83,8%, a especificidade, de 81,8%, e a precisão, de 82,8%. A sensibilidade da tomografia computadorizada foi de 81,1%, a especificidade, de 63,6%, e a precisão, de 72,8%. CONCLUSÃO: Os resultados da broncoscopia confirmaram a sua importância no diagnóstico do câncer pulmonar, pela dependência deste no exame anatomopatológico do tecido ou células, obtido por várias técnicas de biópsia. A tomografia computadorizada apresentou boa sensibilidade, de 81,1%, contudo, a sua especificidade, de apenas 63,6%, resulta do número de falso-positivos (36,4%).
