Abstract
BACKGROUND
The incidence of multiple primary lung cancer (MPLC) in China is 0.52%-2.45%. Most primary lung cancer cases have reported two lesions or three in rare cases. We report a rare case of bilateral simultaneous multiple primary lung adenocarcinoma of four different genotypes.
CASE SUMMARY
A 58-year-old woman was admitted to our hospital on June 29, 2021, and upon physical examination, four multiple pulmonary nodules were identified in both lungs. Further computed tomography (CT) images revealed the presence of ground glass nodules, predicted to be high-risk cancer lesions by artificial intelligence. With the guidance of three-dimensional reconstruction of preoperative CT images, the nodules were resected under thoracoscopy. Postoperative pathological investigation revealed that the nodule types were adenocarcinoma in situ, invasive alveolar adenocarcinoma, and microinvasive adenocarcinoma. The excised nodules were further sequenced using high-throughput sequencing (semiconductor sequencing method) of 26 lung cancer genes to confirm that the four lesions were not homologous. The patient was discharged on postoperative day 8, that is, on July 15, 2021. One month later, she returned to the hospital for follow-up and reexamination. Chest CT examination showed that she had recovered well, and no obvious exudation and effusion were found in both pleural cavities. Evaluation of postoperative pulmonary function showed that her forced vital capacity was 1.40 L (preoperative value, 2.27 L) and forced expiratory volume was 1.24 L (preoperative value, 2.23 L).
CONCLUSION
The surgical plan for multiple pulmonary nodules should be carefully considered. For carefully selected patients with concurrently occurring multiple lung nodules in both lungs, sublobectomy is a safe and feasible plan for concurrent bilateral resection of the lesions. Genetic sequencing is necessary for MPLC diagnosis and treatment.
Core Tip: In this case, nodules in bilateral four lobes were resected simultaneously via video-assisted thoracic surgery. Postoperative pathological and genetic analyses revealed that the types of nodules were left upper lobe adenocarcinoma in situ [epidermal growth factor receptor (EGFR) exon 21], left lower lobe invasive adenocarcinoma (Erb-B2 receptor tyrosine kinase 2 exon 20 and tumor protein p53 exon 8), and right upper lobe microinvasive adenocarcinoma (EGFR exon 19), and right lower lobe microinvasive adenocarcinoma (EGFR exon 18). Genetic examination is of decisive significance in the identification of multiple lung cancers and metastatic cancers.
