METHODS: We retrospectively analyzed 208 consecutive patients (146 men and 62 women) with NSCLC treated with 3D-CRT. The median age of the patients was 64 years (range 35-87 years). The clinical and treatment parameters including gender, age, performance status, sequential chemotherapy, concurrent chemotherapy, presence of carinal or subcarinal lymph nodes, pretreatment weight loss, mean dose to the entire esophagus, maximal point dose to the esophagus, and percentage of volume of esophagus receiving ＞55 Gy were studied. Clinical and dosimetric factors for radiation-induced acute and late grade 3-5 esophageal injury were analyzed according to Radiation Therapy Oncology Group (RTOG) criteria.RESULTS: Twenty-five (12%) of the two hundred and eight patients developed acute or late grade 3-5 esophageal injury. Among them, nine patients had both acute and late grade 3-5 esophageal injury, two died of late esophageal perforation. Concurrent chemotherapy and maximal point dose to the esophagus ≥60 Gy were significantly associated with the risk of grade 3-5 esophageal injury. Fifty-four (26%) of the two hundred and eight patients received concurrent chemotherapy. Among them, 25 (46%) developed grade 3-5 esophageal injury (P = 0.0001＜0.01). However, nograde 3-5 esophageal injury occurred in patients who received a maximal point dose to the esophagus ＜60 Gy (P= 0.0001＜0.01).CONCLUSION: Concurrent chemotherapy and the maximal esophageal point dose ≥60 Gy are significantly associated with the risk of grade 3-5 esophageal injury in patients with NSCLC treated with 3D-CRT.展开更多

Methods： We described simultaneous surgery performed on 49 cases with both esophaoeal carcinoma and buUous emphysema, accounting for 2.5% of all esophagectomy patients from January 2000 to January 2003. Radical resection of upper and mid-thoracic esophageal cancer was performed in 31 cases, including three approaches from the right chest, left neck and midsection. Thirty-six patients were underwent cervical anastomosis and 13 cases were operated by intrathoracic anastomosis. Results： No perioperative period death occurred. And postoperative com- plications were as follows： cervical anastomotic leakage in 9 cases, lung infection in 11 cases, pulmonary air leak in 13 cases （2 cases lasted for 4 weeks）, recurrent laryngeal nerve damage in 4 cases, supraventricular tachycardia in 4 cases. Patients all recovered and left the hospital with average hospitalization time of 17.5 days. Conclusion： Patients with both esophageal carcinoma and bullous can perform the esophageal carcinoma resection and lung volume reduction surgery （LVRS） simulta- neously. It will not increase the mortality rate and show the feasibility and safety in patients.展开更多
