Initial lung cancer can be cured by minimally invasive surgery

Professor Moon Young Kyu

The early stage of lung cancer is characterized by minimal resection of the lungs, Lymph node dissection is also useless for tumors that can be treated and have definite lymph node metastasis, [19659004] Three studies that investigated the incidence and prognosis of early-stage autosomal lung cancer by badyzing a patient who underwent lung cancer surgery at St. Mary's Hospital in Seoul, at the same time. 39, Catholic University of Seoul. Published in the journal "World Journal of Surgery". (November 2017, February 2018, May 2018)

Early surgery for lung cancer recommends that the distance between the tumor and the incision be at least 2 cm, or that the lung be cut to a distance greater than the diameter of the tumor.

However, among the 91 patients who had partial lung removal at Saint Mary's Hospital in Seoul from 2004 to 2013, the results of a predominantly lung cancer surgery of liver revealed that the distance between the tumor and the incision was The recurrence-free survival rate was 100% for 5 years, although it was as short as 5 mm or less.

In addition, from 2008 to 2015, 133 patients who underwent surgery to remove only a portion of the lungs were clbadified as pathological tissues to study the distance between the tumor and the incision. However, the recurrence-free survival rate was 100% for 5 years, although the distance between the tumor and the incision was shorter in these adenocarcinomas.

We badyzed 486 patients who underwent standard lung cancer surgery (lobectomy and mediastinal lymph node dissection) and were diagnosed as preoperative early-stage lung cancer from 2005 to 2016 to confirm tumors without lymph node metastasis.

Although the first stage is diagnosed by preoperative imaging, it can be confirmed as a high stage of postoperative biopsy. As a result, 42 patients (8.6%) were diagnosed as 2 or 3 postoperative stage.

In addition, the smaller the tumor size, the lower the risk of lymph node metastasis,

In other words, lung cancer diagnosed as the first stage of preoperative examination , lung cancer of small size (less than 1,2cm) or mainly of the liver shadow (with solid nodules size ratio less than 0.5) The interest rate was 0%.

Lung cancer with a liver shadow is known to have a very good prognosis after surgery, and pulmonary resection or resection of the pulmonary wedge has been used instead of conventional pulmonary resection. ]

However, it is not known how long it will take to remove the lungs from the tumor and to remove all lymph nodes around the lungs if only a portion of the lung is removed.

Professor Moon Young-gyu presented the theme of "Surgical Treatment of Lung Cancer with Liver Tumor" at the 32nd Spring Meeting of the Korean Society of Thoracic and Vascular Surgery

"Lung Cancer can be applied to various surgical procedures depending on the shape and characteristics of the tumor, said Dr. Moon, which allowed to plan and execute more accurately the lung surgery surgery. Explain The significance of the study.

He added, "It is important to accurately determine the extent and stage of the disease by different diagnostic methods prior to lung cancer surgery. "
