RESUMO
@#Objective To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. Methods We 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.
RESUMO
Pulmonary inflammatory myofibroblastic tumor (PIMT) is a rare lung tumor that is poorly understood by clinicians. Based on the data of patients with PIMT in our center, a comprehensive search and a brief summary analysis of previous reports of the disease were carried out in this article. PIMTs were more likely to be present in male patients and in the right lung, and their clinical and radiographic findings were heterogeneous. Surgery is the most important treatment method, and complete resection is of great significance to the prognosis of patients. Targeted therapy represented by crizotinib may be helpful for patients with positive ALK mutations.
RESUMO
@#Thymic neuroendocrine tumors (TNETs) are a series of rare diseases with aggressive biology and poor prognosis. Clinical manifestations of TNETs are atypical, and ectopic secretion of adrenocorticotropic hormone can be found in some cases, resulting in associated endocrine symptoms. Due to the low morbidity and strong heterogeneity, it’s difficult to diagnose, treat and obtain new treatment regimen. Early complete surgical resection is an effective treatment. For advanced cancer, clinical trials of new drugs are expected to improve the survival of patients.
