Objective To analyze the safety of surgical treatment and optimal surgical procedure for lung cancer patients with prior history of lung resection. Methods The medical records of 69 lung cancer patients with history of lung resection was retrospectively collected. There were 53 males and 16 females with a median age of 68 years ranging from 45 to 80 years. The risk factors for postoperative complications were analyzed using one-way ANOVA and logistic regression analysis. By comparing the data between the lobectomy and sublobectomy groups, the best surgical procedure was chosen. Results The 90-day mortality rate was 4.3%. Postoperative complication rate was 24.6%. Results of one-way ANOVA showed that blood loss during operation (P=0.020), tumor size (P=0.007), smoking (P=0.028) and FEV1%pre (P=0.018) were associated with increased major postoperative complications. Logistic regression analysis showed that FEV1%pre<77.0% (OR=0.935, 95%CI 0.888 to 0.984, P=0.010) and tumor size≥2 cm (OR=4.288, 95%CI 1.375 to 13.373, P=0.012) were independent risk factors for major postoperative complications. Lobectomy and sublobectomy groups had similar postoperative mortality and complication rate (P=0.063). Conclusion Surgical resection for selected lung cancer patients with history of lung resection is safe with low postoperative mortality and complication rate. Lobectomy with lymph node resection is the first choice if cardiopulmonary function permits. Pneumonectomy is not recommended.
Objective To observe the turbulence of regional intra-artery implantation chemotherapy and peripheral venous chemotherapy on immunologic function of patients. Methods Two weeks after radical operation of gastric carcinoma, chemotherapy was performed. Eighty-three patients were divided into two groups, one (42 patients) received peripheral venous chemotherapy (PVC) and the other (41 patients) received regional intra-artery implantation pump chemotherapy (RAIPC). The serum T-lymphocyte subsets and immunoglobulin level before and 1-4 days after the chemotherapy were measured. Results After PVC, proportion of CD3 and CD4, CD4/CD8 and IgG, IgA, IgM concentration in PVC group were significantly decreased compared with those before PVC （P＜0.05， P＜0.01）, and it is the same when compared with postRAIPC patients except for CD4 and IgM （P＜0.05）. In RAIPC group, there were no significant changes in proportion of CD3, CD4 and CD8, CD4/CD8 and IgG, IgA concentration between pre- and post-RAIPC patients. Conclusion After radical operation of gastric carcinoma, RAIPC affects the immunologic function more moderate than PVC.
Objective To explore the safety and feasibility of preferential manual bronchoplasty in single-port video-assisted thoracoscopic surgery (VATS) upper lobectomy. MethodsThe clinical data of 457 patients with non-small cell lung cancer who underwent single-port VATS lobectomy in the Department of Thoracic Surgery of Peking University First Hospital from March 2020 to March 2022 were retrospectively analyzed. The patients were divided into a preferential manual bronchoplasty group and a traditional single-port VATS lobectomy group with a 1 : 1 propensity score matching for further research. Results A total of 204 patients were matched, and there were 102 patients in each group. There were 50 males and 52 females aged 62.2±10.1 years in the preferential bronchoplasty group, and 49 males and 53 females aged 61.2±10.7 years in the traditional single-port VATS group. The preferential bronchoplasty group had shorter surgical time (154.4±37.0 min vs. 221.2±68.9 min, P<0.01), less bleeding (66.5±116.9 mL vs. 288.6±754.5 mL, P=0.02), more lymph node dissection (19.8±7.5 vs. 15.2±4.7, P<0.01), and a lower conversion rate to multi-port or open surgery (2.3% vs. 13.8%, P=0.04) in left upper lobe resection. In the right upper lobe resection surgery, there was no statistical difference in postoperative results between two groups. There was no perioperative death or occurrence of bronchopleural fistula in both groups. ConclusionCompared with traditional single-port VATS upper lobectomy, preferential bronchoplasty has similar safety and feasibility. In addition, priority bronchoplasty in left upper lobectomy has the advantages of shorter surgical time, less bleeding, more lymph node dissection, and lower conversion rate to multi-port or open surgery.
