A 65-year-old-male had a mass in the oral cavity, and this was ultimately determined to be squamous cell carcinoma and he underwent wide excision for it. Postoperatively, he underwent the staging work up; this showed that he had other cancers in the esophagus, stomach and lung. We performed a curative resection of all the lesions simultaneously. We report here on a case of synchronous multiple cancers of the esophagus, stomach, lung and oral cavity.

BACKGROUND: Many recent results of clinical trials show that pre-operative concurrent chemoradiotherapy and surgical resection could increase the survival of N2 positive stage IIIA non-small cell lung cancer. This study was performed to assess the feasibility, toxicity, and affect rates of concurrent chemoradiotherapy and surgical resection in N2 positive stage IIIA non-small cell lung cancer. MATERIAL AND METHOD: Thirty-one patients who underwent preoperative concurrent chemoradiotherapy for N2 positive stage IIIA non-small-cell lung cancer from May 1997 to April 1999 were entered into the study. Mean age was 61 yrs (43-70 yrs), There were 24 men and 7 women. The confirmation of N2 disease were achieved through mediastinoscopic biopsy (24) and CT scans (7). Induction was achieved by two cycles of cisplatin and etoposide(EP) plus concurrent chest radiotherapy to 45 Gy. Resections were done at 3 weeks after the complection of preoperative concurrent chemoradiotherapy. Resections were performed in 23 patients, excluding 5 refusals and 3 distant metastasis. All patients were compled the thoracic radiotherapy except one who had distant metastasis. Twenty three patients were completed the planned 2 cycles of EP chemotherapy, and 8 patients were received only 1 cycle for severe side effects (6), refusal (1), and distant metastasis(1). There was one postoperative mortality, and the cause of death was ARDS. Three patients who had neutropenic fever and one patient who had radiation pneumonitis were required admission and treatment. Esophagitis was the most common acute side effect, but relatively well-tolerated in most patients. The complection rate of concurrent chemoradiotherapy was 74%, resection rate was 71%, pathologic complete remission rate was 13.6%, and pathologic down-staging rate was 68%. CONCLUSION: Morbidity related to each treatment was acceptable and many of the patients have benefited down staging of its disease. Further prospective, preferably randomized, clinical trials of larger scale may be warranted to confirm the actual benefit of preoperative concurrent chemoradiotherapy and surgical resection in N2-positive stage IIIA non-small cell lung cancer.

Fibrovascular polyp of the esophagus is a rare and benign pedunculated intraluminal tumor. The tumor consists of varying amount of vascular fibrous and adipose tissue that arises in the submucosa and is covered by squamous epithelium. We report the typical radiographic, CTand MR findings of a case of giant fibrovascular polyp of the esophagus.

An accessory cardiac bronchus (ACB) is a rare congenital anomaly of the trachobronchial tree. It rarely presents with symptoms, and is usually diagnosed incidentally by chest CT, bronchoscopy, or during surgery. We experienced a case of accessory cardiac bronchus found incidentally in the bronchus intermedius with lung cancer in the right lower lobe, and surgically removed.

BACKGROUND: Because of the common etiologic factor, such as smoking, lung cancer and chronic obstructive Pulmonary disease are often present in the same patient. The preoperative prediction of remaining pulmonary function after the resectional surgery is very important to prevent serious complication and postoperative respiratory failure. 99mTc-MAA perfusion scan has been used for the prediction of postoperative pulmonary function, but it may be inaccurate in case of large V/Q mismatching. We compared 99mTc-DTPA radioaerosol inhalation scan with 99mTc-MAA perfusion scan in predicting postoperative lung function. METHOD: Preoperative inhalation scan and/or perfusion scan were performed and pulmonary function test were performed preoperatively and 2 month after operation. We predicted the postoperative pulmonary functions using the following equations. Postpneumonectomy FEV1=Preop FEV1x% of total function of lung to remain RESULTS: 1) The inhalation scan showed good correlations between measured and predicted FEV1, FVC and FEF25-75%. (correlation coefficiency; 0.94, 0.91, 0.87 respectively). 2) The perfusion scan also showed good correlations between measured and predicted FEV1, FVC and FEF25-75%. (correlation coefficiency; 0.86, 0.72, 0.97 respectively). 3) Among three parameters, FEV1 showed the best correlations in the prediction by lung scans. 4) Comparison between inhalation scan and perfusion scan in predicting pulmonary function did not show any significant differneces except FVC. CONCLUSION: The inhalation scan and perfusion scan are very useful in the prediction of postoperative lung function and don't make a difference in the prediction of pulmonary function although the former showed a better correlation in FVC.
