Abstract

Introduction: This study aimed to investigate the interval between the diagnosis and definitive surgical treatment of lung cancer patients at a public institution in São Paulo.

Method: A retrospective observational study was conducted, using medical records to collect data on the periods between the first abnormal chest computed tomography (CT) scan, the initial consultation with the specialist, and the subsequent tumor resection.

Results: The analysis of 20 patients revealed a substantial average waiting period of 425.6 days between diagnosis and definitive treatment. During this interval, an average of 282 days elapsed between diagnosis and the initial specialist consultation, while the period between the first consultation and treatment averaged 143 days. By comparing the initial and final staging, 70% of the patients progressed to a higher stage over this period.

Conclusions: The identified interval is concerning and exposes patients to elevated risks during this waiting period. This prolonged duration poses potential threats to patient health, resulting in decreased quality of life, increased risk of disease progression, reduced chances of cure, and diminished overall survival prospects. Addressing and minimizing this extended interval is crucial for improving patient outcomes and enhancing the effectiveness of lung cancer treatment.

圣保罗某公共机构肺癌诊断与最终治疗间隔的评估。

简介：本研究旨在调查在圣保罗公立机构肺癌患者的诊断和最终手术治疗之间的时间间隔。方法：采用回顾性观察研究方法，收集患者首次胸部异常CT扫描、首次专科会诊到后续肿瘤切除的病历资料。结果：对20例患者的分析显示，从诊断到最终治疗，平均等待期为425.6天。在此期间，从诊断到初次专家会诊的平均时间为282天，而从初次会诊到治疗的平均时间为143天。通过比较初始和最终分期，70%的患者在此期间进展到更高阶段。结论：确定的间隔令人担忧，并使患者在此等待期间面临更高的风险。这种持续时间的延长对患者健康构成潜在威胁，导致生活质量下降，疾病进展风险增加，治愈机会减少，总体生存前景下降。解决和最小化这一延长间隔对于改善患者预后和提高肺癌治疗的有效性至关重要。

期刊介绍： History: The publication and dissemination of scientific activities of its members is one of the aims of medical societies. The Brazilian College of Surgeons (Colégio Brasileiro de Cirurgiões – CBC), founded in 1929, already in its first statute provided for the issuance of the “Bulletin of the Brazilian College of Surgeons” as its official division, whose starting number was published in January 1930. In 1967, the National Directory of CBC changed its name to "Journal of the Brazilian College of surgeons", which, however, went on to be published without due regularity. From 1974 on, the journal began to be published bi-monthly, on a regular basis, to the present day. In these more than 40 years of uninterrupted publication, the Journal of the CBC gained importance and scope. With standards and criteria for selection and publication of scientific articles in the area of General and specialist Surgery, including "peer review", the Journal of the CBC falls along the lines of the main international journals and has an Editorial Board that evaluates the merits for publication of submitted manuscripts.
