P1.02-014 - Predictive Factors of Postoperative Acute Exacerbation of Interstitial Pneumonia for Patients with Lung Cancer (ID 3048)
09:30 - 09:30 | Author(s): H. Yukiue
- Abstract
Background:
Currently, postoperative acute exacerbation (AE) of idiopathic interstitial pneumonia (IIP) accounts for the most common cause of death after pulmonary resection for lung cancer. Preoperative risk assessment and prevention of postoperative AE is essential for the operative performance improvement.
Methods:
From 2000 through 2013, a total of 1730 patients underwent pulmonary resections for primary lung cancer. One hundred and two patients (5.9%) were diagnosed the lung cancer combined with IIP based on the postoperative pathological findings. Postoperative AE was defined as acute exacerbation within 30 days after the operation.
Results:
Postoperative AE was observed in 9 patients (8.8%), of which 6 patients (66.7%) died of respiratory failure. Although three patients had improved and discharged, two patients of which finally died with re-exacerbation. All of the postoperative AE patients were men having all cases smoking history, and many of them were advanced stage. The AE patients were significantly worse than non-AE patients in following clinicopathological factors. Preoperative serum LDH（248±52IU/l vs 206±45）、CRP（1.6±1.8mg/dl vs 0.9±1.8）、PaO2（78.1±7.8mmHg vs 84.9±10.5） and ％VC（78.9±14.3% vs 94.4±15.1）. Moreover, for the postoperative AE patients, the changes of these factors and X-ray or CT findings before operation were analyzed. An exacerbation before operation observed for serum LDH in five patients, CRP in three patients, and increased lung opacity on imaging findings observed in four patients.
Conclusion:
To see the exacerbation of laboratory values (LDH, CRP) and imaging findings (increasing lung opacity) during preoperative time, there is a possibility of selecting high-risk patients of postoperative AE.

P2.01-049 - Surgical Treatment Results of T4 Lung Cancer Invading Mediastinum (ID 387)
09:30 - 09:30 | Author(s): H. Yukiue
- Abstract
Background:
Inoperable cases are common in T4 lung cancer patients, and their prognoses are mostly poor. Nevertheless, among those who undergo resection, some can achieve long-term survival. We reviewed the validity of surgical treatment for T4 lung cancer at our department.
Methods:
Fifty-six cases of pathologically confirmed T4 lung cancer resection between January 1989 and December 2013 were selected for this study. Cases of nodules in different lobes of the same lung were ineligible. The relationships among the number of infiltrated organs, pN factor, presence or absence of preoperative treatment, histological effect (Ef), and surgical curative rate and prognosis were assessed using statistical techniques.
Results:
The subjects consisted of 53 males and 3 females with an average age of 62.2 years. Depending on the histological types, they were classified as squamous cell cancer (29 cases), adenocarcinoma (16 cases), adenosquamous cancer (7 cases), large cell cancer (1 case), and other cancers (2 cases). Also, there were 37 single and 19 multiple organ infiltration cases, which were classified by infiltrated organ as 16 in the trachea and tracheal bifurcation, 11 in the vertebral body, 10 in the aorta, 10 in the superior vena cava, 9 in the mediastinum, 6 in the left atrium, 6 in the pulmonary artery, 5 in the esophagus, and 2 in the subclavian artery, including duplicated cases. Preoperative treatment was carried out in 22 cases (chemoradiotherapy, 14; chemotherapy, 8), whose histological effect was Ef0-1 in 13 and Ef2-3 in 9. The surgical curative rate was complete resection in 27 and incomplete resection in 29; complete resection was common in those receiving preoperative treatment. There were no death cases within 30 days after the surgery. In all cases, the five-year survival rate was 21.7% and median survival time (MST) was 16.5 months. The five-year survival rate was 27.5% in single organ infiltration compared with 15.8% in multiple organ infiltration (P = 0.08), 27.5% in n0-1 versus 13.8% in n2-3 (P = 0.30), 36.8% with preoperative treatment in contrast to 11.2% without preoperative treatment (P = 0.06), 9.4% in Ef0-1 as opposed to 76.2% in Ef2-3 (P = 0.05), and 37.7% in complete resection in comparison with 7.8% in incomplete resection (P = 0.003). Long-term survival over 5 years was noted in 7 cases (12.5%), 4 of which involved single organ infiltration, n0-1, preoperative treatment, and Ef2-3.
Conclusion:
Single organ infiltration and n0-1 are good surgical indications for T4 lung cancer, and a favorable prognosis can be expected if preoperative treatment and complete resection are performed.
