Abstract： Surgery is an effective therapy for non-small cell lung cancer (NSCLC). The standard operation includes lobectomy and systematic dissection of lymph nodes. However, postoperative tumor recurrence is common even among incipient patients due to incomplete dissection of lymph nodes and micrometastasis of lymph nodes. Injecting a carbon nanoparticles suspension is a new technique aimed at preventing this recurrence. The carbon nanoparticles carry lymph node tracers that help surgeons locate lymph nodes in order to clean them thoroughly. The tracers also target the lymph nodes for chemotherapy, thus killing residual tumor cells intraoperatively to avoid postoperative cancer recurrence. Carbon nanoparticles suspension injection is already widely and successfully used in surgery for gastrointestinal and mammary gland tumors, and is being tested for effectiveness in NSCLC patients. Some studies have indicated that carbon nanoparticles suspension injection is effective in NSCLC patients and improves their prognoses. We reviewed the features, application methods, and clinical applications of studies of carbon nanoparticles suspension injection for NSCLC.
ObjectiveTo discuss the causes of esophageal benign diseases and how to prevent, diagnose and treat such diseases. MethodsWe reviewed and analyzed the clinical data of 162 patients with esophageal benign diseases treated in our hospital from March 1994 to July 2011. Causes, diagnosis, treatment and prognosis of this kind of diseases were analyzed and summarized. ResultsEighty-five patients had definite inducements. All patients were diagnosed through barium swallow radiography, CT, and gastroscopic inspection and underwent operation. A total of 155 patients were cured by positive treatment, but 7 patients died because of severe infection. ConclusionMost patients suffering from esophageal benign diseases have definite inducements. Therefore, many such diseases can be prevented. Once being confirmed, active surgery is the main treatment. Most patients can be cured if treatment is performed in time.
