The incidence and mortality of lung cancer are increasing globally. With the spread of CT, more and more early-stage lung cancer can be detected and treated in a timely manner. As the main treatment of lung cancer, thoracoscopic anatomical segmentectomy in the treatment of non-small cell lung cancer is causing concern to the thoracic surgeons. Here, we will discuss the application of thoracoscopic anatomical segmentectomy in the treatment of early non-small cell lung cancer.
Lung cancer, as one of the malignant tumors with the fastest increasing morbidity and mortality in the world, has a serious impact on people's health. With the continuous advancement of medical technology, more and more medical methods are applied to lung cancer screening, which has gradually increased the detection rate of early lung cancer. At present, the standard operation for the treatment of early non-small cell lung cancer (NSCLC) is still lobectomy and mediastinal lymph node dissection. There is a growing trend to use segmentectomy for the treatment of early stage lung cancer. Anatomical segmentectomy not only removes the lesions to the maximum extent, but also preserves the lung function to the greatest extent, and its advantages are also obvious. This article reviews the progress of anatomical segmentectomy in the treatment of early NSCLC.
Objective To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. MethodsWe retrospectively enrolled 100 patients who underwent VATS segmentectomy for bilateral lung cancer at the Department of Thoracic Surgery of Peking Union Medical College Hospital from December 2013 to May 2022. We divided the patients into two groups: a one-stage group (52 patients), including 17 males and 35 females with a mean age of 55.17±11.09 years, and a two-stage group (48 patients), including 16 males and 32 females with a mean age of 59.88±11.48 years. We analyzed multiple intraoperative variables and postoperative outcomes. Results All 100 patients successfully completed bilateral VATS, and at least unilateral lung received anatomical segmentectomy. Patients in the one-stage group were younger (P=0.040), had lower rate of comorbidities (P=0.030), were less likely to have a family history of lung cancer (P=0.018), and had a shorter interval between diagnosis and surgery (P=0.000) compared with patients in the two-stage group. Wedge resection on the opposite side was more common in the one-stage group (P=0.000), while lobectomy was more common in the two-stage group. The time to emerge from anesthesia in the one-stage group was longer than that in the first and second operations of the two-stage group (P=0.000, P=0.002). Duration of surgery and anesthesia were similar between two groups (P>0.05). Total number of lymph node stations for sampling and dissection (P=0.041) and lymph nodes involved (P=0.026) were less in the one-stage group. Intraoperative airway management was similar between two groups (P>0.05). The one-stage group was associated with lower activities of daily living (ADL) scores. Conclusion Segmentectomy is safe in one- or two-staged VATS for bilateral lung cancer, including contralateral sublobectomy and lobectomy. Duration of surgery and perioperative complications are similar between two groups, but the one-stage group is associated with lower ADL scores. On the basis of comprehensive consideration in psychological factors, physical conditions and personal wishes of patients, one-staged sequential bilateral VATS can be the first choice.
ObjectiveTo explore the efficacy of single-port thoracoscopic anatomical lung segmentectomy in treating Stage IA non-small-cell lung cancer (NSCLC) and to analyze its impact on the body's stress response and lung function. MethodsA retrospective analysis was conducted on the clinical data of patients with stageⅠA NSCLC admitted to the Second Affiliated Hospital, Air Force Military Medical University, from January 2021 to June 2022. Patients were divided into two groups based on their treatment plans: those who underwent single-port thoracoscopic lobectomy were in the lobe group, and those who underwent single-port thoracoscopic anatomical lung segmentectomy were in the segment group. The surgical-related indicators, complication rates, survival rates of the two groups were compared, as well as the body's stress response indicators before and after surgery [C-reactive protein (CRP), interleukin-6 (IL-6), cortisol (Cor), creatine kinase (CK)], prognostic lung function indicators [forced vital capacity (FVC), maximal voluntary ventilation (MVV), forced expiratory volume in one second (FEV1), FEV1/FVC ratio], and auxiliary tumor markers [carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), CA724, cyto-keratin 21-1 fragment (CYFRA21-1)]. ResultsEach group included 53 patients, with 29 males and 24 females in the segment group, with an average age of (70.38±3.67) years; and 26 males and 27 females in the lobe group, averaging an age of (71.09±3.80) years. The intraoperative blood loss in the segment group was less than that in the lobe group [(118.41±14.58) mL vs. (130.36±10.61) mL, P＜0.001], and the hospital stay was shorter in the segment group [(7.13±1.14) d vs. (8.52±1.33) d, P＜0.001]. One day and three days post-surgery, the serum levels of CRP, IL-6, Cor, and CK in the segment group were lower those in the lobe group, while the levels of FVC, FEV1, FEV1/FVC ratio, and MVV were higher (P＜0.05). One month and three months post-surgery, the serum levels of CEA, CA125, CA724, and CYFRA21-1 in the segment group showed no statistically significant difference compared to the lobe group (P＞0.05); the incidence of postoperative complications and survival rates in the segment group were 3.77% and 80.39%, respectively, while they were 7.55% and 76.92% in the lobe group, respectively, with no statistical difference between the two groups (P＞0.05). ConclusionSingle-port thoracoscopic anatomical lung segmentectomy for stage ⅠA NSCLC has significant advantages in reducing intraoperative damage, stabilizing the body's stress response, and has less impact on lung function, which is beneficial for postoperative recovery.
