Identification of the top 100 cited articlesBetween July and August 2018 , we performed a retrospective bibliometric analysis, identifying articles through the Web of Science (Thomson Reuters, New York, USA) which searches the Science Citation Index Expanded database, allowing access to over 12,000 peer reviewed journals and collected citation data published since 1945.Using selected key terms ("lung cancer", "surgery'", "lobectomy", "segmentectomy", "pneumonectomy", "wedge resection", "video-assisted thoracic surgery", "thoracotomy"), our search performed between July and August 2018 yielded a total of 18,268 articles. The top 100 articles were identified subsequently which were ranked by the number of citations.
Analysis of the top 100 cited articlesA further analysis of individual articles was carried out by three reviewers (J Shen, K Jin, and Q Hu) to extract relevant information for the analysis. Individual articles were reviewed to identify the authorship, journal title, journal IF, subject matter, article type (e.g., prospective analysis, retrospective analysis, meta-analysis or systematic review, randomized controlled trial, review article, guideline, technical note, or case report), institution and country of origin, level of evidence, and year of publication. The analysis method used the Australian National Health and Medical Research Council evidence hierarchy (11). Of note, this classification defines clinical guidelines as level I evidence and randomized control trials as level II evidence.Furthermore, the citation count and citations per year were extracted using the Web of Science. When there was disagreement or discordance between reviewers, the senior author (D Ma) was included to achieve consensus.
ResultsThe top 100 articles regarding the thoracic surgery management of lung cancer according to the most citations received are listed in Table 1."Cisplatin-based adjuvant chemotherapy in patients with completely resected non-small-cell lung cancer", published in The New England Journal of Medicine in 2004, has received totally 1,720 citations, the most citations in the past 14 years. Of note, it also remains the most cited article per year, being cited 122.86 times on average, per year. The article with the lowest number of citations in the top 100 list, "A practical molecular assay to predict survival in resected non-squamous, non-small-cell lung cancer: Development and international validation studies", received 177 citations. Overall, the mean number of citations was 356, with the top 100 articles cited an average of 26 times per year.Only one of the top 100 articles was published prior to 1980 (Table 2), with 63% (n=63) published since the year 2000 and 13% published within the past decade. Eighteen authors contributed four or more articles (Table 3). Rusch, Ginsberg, Johnson, and Livingston have contributed the most articles. Rusch and Ginsberg were the first named authors on four articles each. Rusch is the most published author, appearing on a total of ten articles.A total of 31 journals mad...
