Abstract
This study aims to assess the influence of esophagectomy with gastric transposition on the gastroesophageal reflux (GER) and gastric acidity in patients with esophageal cancer. Data on 53 esophageal cancer patients who underwent 24-hour impedance-pH monitoring after esophagectomy were retrospectively analyzed. We used a solid-state esophageal pH probe in which the esophageal pH sensor is placed 1.5 cm distal to the upper esophageal sphincter and the gastric pH sensor is located 15 cm distal to the esophageal pH channel. 24-hour impedance-pH monitoring data and other clinical data including anastomosis site stricture and incidence of pneumonia were collected. We defined pathologic reflux with reference to known normative data. Stricture was defined when an intervention such as bougienage or balloon dilatation was required to relieve dysphagia. The esophageal and gastric mean pH were 5.47 ± 1.51 and 3.33 ± 1.64, respectively. The percent time of acidic pH (<4) was 6.66 ± 12.49% in the esophagus and 70.53 ± 32.19% in the stomach. Esophageal pathologic acid reflux was noticed in 32.1%, 20.8%, and 35.8% during total, upright, and recumbent time, respectively. Esophageal pathologic bolus reflux was noted in 83.0%, 77.4%, and 64.2% during total, upright, and recumbent time, respectively. Gastric acidity increased with time after esophagectomy. Esophageal acid exposure time correlated with intragastric pH. However, esophageal pathologic acid reflux was not associated with anastomosis site stricture or pneumonia. In conclusion, GER frequently occurs after esophagectomy. Thus, strict lifestyle modifications and acid suppression would be necessary in patients following esophagectomy.

Abstract
BACKGROUND To evaluate the long-term needs of lung cancer survivors and to explore factors associated with unmet need. PATIENTS AND METHODS We recruited lung patients treated with curative surgery from 2001 through 2006 at two centers in Korea. Needs in the domains of information, supportive care, education and counseling, and socioeconomic support were measured. We selected the four most frequently reported items of unmet need among 19 items in four domains. RESULTS The most frequently reported unmet needs were Complementary and alternative medicine (CAM) and folk remedies (59.8%) in the Information domain, Counseling and treatment of depression and anxiety (63.5%) in the Supportive care domain, diet, exercise and weight control (55.1%) in the Education and counseling domain and Financial support (90.4%) in the socioeconomic support domain. Unmet needs for psychological treatment was significantly greater in participants who were employed (adjusted odds ratio [aOR], 2.25; 95% confidential interval [CI], 1.12 to 4.53). Unmet needs for diet, exercise and weight control were significantly greater in participants who had not received chemotherapy (aOR, 1.76; 95% CI, 1.09 to 2.85). Unmet need for financial support was greater in participants who were married (aOR, 4.14, 95%CI, 1.12 to 15.22) and those who had not received chemotherapy (aOR, 5.91, 95%CI, 1.91 to 18.31). CONCLUSION There were substantial unmet needs for information regarding psychological support, education for diet and exercise, and financial support among lung cancer survivors.

Abstract
Chest radiographs and CT scans, obtained in six patients with proven postpneumonectomy empyema, were retrospectively reviewed by comparing the radiologic image obtained at present with that obtained before symptom onset. Convexity or straightening of the concave mediastinal margin of the postpneumonectomy space was identified on CT scans in all of six patients (100%), while contralateral mediastinal shift was noted on both radiographs and CT scans in four patients (67%). Multiple air-fluid levels appeared equally on radiographs and CT scans in three patients (50%). CT depicted increased thickening of the parietal pleura (n=5, 83%) and the extrapleural tissues (n=3, 50%) and empyema necessitans (n=2, 33%), which were not apparent on radiographs. Postpneumonectomy empyema is characterized on CT scans by reversal of the normal concavity of the mediastinal margin with increased thickening of the residual parietal pleura. CT is superior to radiography in assessing the manifestations of postpneumonectomy empyema.

Abstract
AIMS Basaloid squamous carcinoma (BSC) is an uncommon variant of squamous cell carcinoma, with its prevalent sites being the hypopharynx, tongue base and larynx. In the oesophagus, BSC is rarer than in the head and neck region. This study was aimed to document the clinicopathological features of BSCs of the oesophagus, and to present their relative incidence and immunohistochemical findings. METHODS AND RESULTS Eighteen cases of BSC of the oesophagus, comprising 3.6% of 502 oesophageal carcinomas, were reviewed for their pathological and clinical features, and examined for the immunohistochemical expression of neuroendocrine markers, cytokeratins, p53, pRb and bcl-2. Oesophageal basaloid squamous carcinomas tended to be biphasic or multiphasic carcinomas, most commonly with basaloid and squamous components (eight cases), or with additional adenocarcinoma (three cases) or with small cell carcinoma (two cases). Each component was microscopically clearly distinguishable from the others, and metastasized separately, chiefly the basaloid component. The remaining five cases were apparently pure basaloid carcinomas, being characterized by lobules and nests of monotonous round undifferentiated cells with frequent comedo necrosis. They resembled, but were differentiated from, the small cell carcinoma on the basis of neuroendocrine markers and cytokeratin expression. p53, pRb and bcl-2 oncoprotein, which are known to normally present in the basal/parabasal cells of the oesophageal epithelium, were detected in 40-50% of cases, with a heterogeneous expression pattern. The patients were all male, with the age ranging 47-74 years (median 57) and presented at variable stages. The plotted 3 years survival rate was 51%, and the immunohistochemical expression of p53, pRb and bcl-2 was not related to the survival of the patients. CONCLUSION Basaloid squamous carcinoma of the oesophagus is a peculiar neoplasm with a capacity of multidirectional differentiation, often with heterogeneous oncogene expression, probably reflecting the pluripotential stem cell origin.

Abstract
BACKGROUND Stage II non-small-cell lung cancer is regarded as one of the early lung cancers. Although resection, including the mediastinal lymph nodes, is currently regarded as the standard treatment, the survival rate of this disease is not encouraging. It is well known that the most common causes of death are locoregional recurrences or distant metastases, or both. However, the best adjuvant treatment to improve survival is as controversial an issue as ever. METHODS This study was designed as a randomized, blinded, two-armed study with operation and adjuvant radiotherapy in one arm, versus operation and adjuvant mitomycin C (10 mg/m2), vinblastine (6 mg/m2), and cisplatin (100 mg/m2) (MVP) chemotherapy in the other arm. We assigned 57 resected patients with pathologic proven stage II non-small cell lung cancer to the groups according to our eligibility criteria. RESULTS The most common pattern of recurrence was distant metastases, and nearly all the recurrences (17 of 18 patients) in both groups were found within 2 years after operation. The rates of the locoregional and distant metastases were 3.6% and 46.4% in the adjuvant radiotherapy group and 6.9% and 10.3% in the adjuvant chemotherapy group (p = 0.018). The 5-year disease-free survival rates were 52.0% in the adjuvant radiotherapy group and 74.0% in the adjuvant chemotherapy group (p = 0.16, log-rank test). The 2-year, 5-year, and 6-year survival portions were 60.3%, 56.5%, and 28.3% in the adjuvant radiotherapy group, and 82.8%, 70.1%, and 60.1% in the adjuvant chemotherapy group (p = 0.01, p = 0.17, and p = 0.03, Z-test). The difference of the actuarial survival between these two groups was somewhat significant (p = 0.09, log-rank test). CONCLUSIONS Our results suggest that the addition of adjuvant MVP chemotherapy may reduce the distant metastasis rates and prolong the survival of the surgically resected stage II non-small-cell lung cancer patients.

Abstract
Gastric adenocarcinomas involving the esophagogastric junction represent a particular therapeutic problem because they lie in the border area between two body cavities: the thorax and the abdomen. The prognosis of gastric adenocarcinomas involving esophagogastric junction is poor because there is widespread lymphatic metastasis, making curative resection difficult. Even in patients with localized disease who are potentially curable, the 5-year survival rate is approximately 20% with curative resection only, somewhat lower than for those with cancer elsewhere in the stomach. The authors conducted a pilot study to evaluate the safety and possible efficacy of adjuvant chemotherapy with cisplatin, etoposide, and 5-fluorouracil (PEF) after curative resection of gastric adenocarcinoma involving esophagogastric junction. Three cycles of adjuvant PEF chemotherapy with cisplatin (20 mg/m2/day intravenously on days 1-5), etoposide (100 mg/m2/day intravenously on days 1, 3, and 5), and 5-fluorouracil (800 mg/m2/day continuous intravenous infusion on days 1-5) were given every 3 weeks after curative resection of gastric adenocarcinoma involving the esophagogastric junction. Between November 1989 and June 1995, a total of 50 patients with postoperative stage II, IIIA, or IIIB disease entered this trial. In 14 of 50 patients (28%), the disease recurred during the follow-up of 4-83 months (median 26 months). Disease-free survival was 4-83+ months (median 48 months), and the actuarial 5-year disease-free survival rate was 48% (95% CI: 41% to 55%). Overall survival was 4-83+ months (median 62 months), and the actuarial 5-year survival rate was 54% (95% CI: 40% to 68%). The prognostic factor analysis showed that the postoperative N stage and the interval between surgery and chemotherapy affected disease-free survival and overall survival. The toxicities of PEF adjuvant chemotherapy were leukopenia, nausea/vomiting, and alopecia, but they were mostly mild and reversible except in one patient who died because of treatment-related sepsis. Adjuvant chemotherapy with three cycles of PEF regimen was well tolerated and seems to be a promising treatment for gastric adenocarcinoma involving the esophagopstric junction, in comparison with previous treatments. To define the efficacy of adjuvant PEF chemotherapy for gastric adenocarcinoma involving esophagogastric junction, prospective randomized trials are warranted.

Abstract
PURPOSE The purpose of this study was to evaluate the significance of obliteration of the pulmonary vein in assessing local extent of lung cancer with CT, particularly in regard to intrapericardial extension of tumor through the vein. METHOD Preoperative CT scans of 325 patients, who underwent thoracotomy for primary lung cancer, were reviewed. Among them, CT scans of 19 patients showed obliteration of the pulmonary vein up to its entrance into the left atrium, without filling defect in the left atrium. Surgical records of these patients were then reviewed to investigate the extent of tumor growth through the pulmonary vein, with particular emphasis on intrapericardial extension. RESULTS The surgical records revealed extension of tumor through the pulmonary vein beyond the pericardial reflection in 14 or 19 patients. In 10 patients showing obliteration of either the left of the right superior pulmonary vein, all tumors extended beyond the pericardial reflection (100%). Intrapericardial extension occurred in four of nine patients showing obliteration of either the left or the right inferior pulmonary vein (44%). The difference was statistically significant (p < 0.05). CONCLUSION When assessing local extent of lung cancer with CT, obliteration of the superior pulmonary vein is a highly suggestive finding for intrapericardial extension of tumor through the pulmonary vein. On the contrary, obliteration of the inferior pulmonary vein is believed to be a less reliable finding for intrapericardial extension of lung cancer.

Abstract
OBJECTIVE Differentiation of invasive thymoma from thymic carcinoma is important because of their different clinical behaviors. Retrospectively, we evaluated the CT findings of invasive thymomas and thymic carcinomas to determine the differential points between them. MATERIALS AND METHODS We reviewed the CT scans of 12 patients with invasive thymoma and 10 patients with thymic carcinoma that were confirmed by surgery or percutaneous needle aspiration. We analyzed CT scans, paying special attention to homogeneity, attenuation, invasion of adjacent mediastinal structures, pleural implants, mediastinal nodes, and extramediastinal metastases. RESULTS Most of the invasive thymomas and thymic carcinomas were homogeneous and isodense with chest wall muscle. Irregular infiltration into the adjacent organ suggesting invasion was seen in 11 patients (92%) with invasive thymoma and 8 patients (80%) with thymic carcinoma. Pleural implants were observed in four patients (33%) with invasive thymoma and one patient (10%) with thymic carcinoma. Mediastinal lymphadenopathy was seen in one patient (8%) with invasive thymoma and four patients (40%) with thymic carcinoma. Metastases to the lung, adrenal glands, or liver were observed in four patients (40%) with thymic carcinoma but none with invasive thymoma. CONCLUSION Despite the similarities of CT findings between invasive thymoma and thymic carcinoma, there are some differential points. Thymic carcinomas were infiltrating tumor and were more commonly associated with mediastinal nodes and extrathymic metastases, but less commonly associated with pleural implants than invasive thymoma.

Abstract
A carcinoid tumor of the thymus combined with thymoma in a 62-year-old man is described. The mediastinal tumor had been present for 13 years and was associated with pure red cell aplasia. Carcinoid tumor occupied the central two-thirds of the tumor, consisting of nests and trabeculae of monotonous round cells, which ultrastructurally showed many intracytoplasmic dense-core granules. Typical spindle cell type thymoma surrounded the carcinoid area. Clinico-pathologic findings of this unique case suggested that the carcinoid tumor developed within a preexisting thymoma, illustrating a possibility of neuroendocrine differentiation of thymic epithelial cells.
