Abstract
OBJECTIVE The purposes of this article are to summarize the relevant literature on aerogenous metastasis, explain the putative pathogenetic mechanism of aerogenous spread, present the characteristic imaging and pathologic features, and review the importance of aerogenous spread to staging and clinical management. CONCLUSION Cumulative evidence suggests that aerogenous spread may exist and is underrecognized. Imaging features are helpful in differentiating possible aerogenous spread of tumor from hematogenous and lymphatic metastases and from synchronous primary tumors. The putative occurrence of intrapulmonary aerogenous metastasis of lung cancer has staging, management, and prognostic implications.

Abstract
尽管用于此修订本的大样本量患者数据库已极大地拓宽了我们的知识面,但最新提出的肺癌分期系统仍以解剖学特征为基础。可以预见,由于所鉴定出的患者亚群数目不断增加,肺癌分期系统变得愈加复杂。表述这些亚组的临床特征有可能为我们提供肿瘤亚组特殊的生物学行为特性的线索。本文探索了可用于以解剖学为基础的新分期系统的肿瘤生物学相关观念。

Abstract
Until additional multi-institutional, randomized, controlled trials provide evidence to the contrary, open lobectomy with mediastinal lymphadenectomy should be considered the gold standard for treating patients with stage I NSCLC with sufficient cardiopulmonary reserve, including older patients. It is the operation with which alternative pulmonary resections, including video-assisted thoracoscopic lobectomy and sublobar resection, should be compared. In treating stage I NSCLC patients, sublobar resection should be reserved for patients with inadequate physiologic reserve to tolerate lobectomy and for those enrolled in clinical trials.

Abstract
Purpose To review recent advances in pathology and computed tomography (CT) of lung adenocarcinoma and bronchioloalveolar carcinoma (BAC). Methods A pathology/CT review panel of pathologists and radiologists met during a November 2004 International Association for the Study of Lung Cancer/American Society of Clinical Oncology consensus workshop in New York. The purpose was to determine if existing data was sufficient to propose modification of criteria for adenocarcinoma and BAC as newly published in the 2004 WHO Classification of Lung Tumors, and to address the pathologic/radiologic concept of diffuse/multicentric BAC. Results Solitary small, peripheral BACs have an excellent prognosis. Most lung adenocarcinomas with a BAC pattern are not pure BAC, but rather adenocarcinoma, mixed subtype with invasive patterns. This applies to tumors presenting with a diffuse/multinodular as well as solitary nodule pattern. The percent of BAC versus invasive components in lung adenocarcinomas appears to be prognostically important. However, a consensus definition of “minimally invasive” BAC with a favorable prognosis could not be achieved. While recognition of a BAC component is possible, the diagnosis of BAC with exclusion of invasive adenocarcinoma cannot be made by small biopsy or cytology specimens. Conclusion There is a need to work toward a mutual understanding and consensus between pathologists, clinicians, and researchers with the use of the term BAC versus adenocarcinoma. Future studies should make some attempt to quantitate these components and/or other features such as size of scar, size of invasive component, or pattern of invasion. Hopefully, this work will allow definition of a category of adenocarcinoma, mixed subtype with predominant BAC/minimal invasion and a favorable prognosis.

Abstract
We present the case of a 70-year-old man who previously had a left upper lobectomy for nonsmall cell lung carcinoma that subsequently developed into small cell carcinoma, which was successfully treated, and finally he had a right upper lobectomy that revealed three synchronous lung malignancies. We were unable to find a previous case report with a total of five separate lung malignancies with a combination of metachronous and synchronous tumors. This case demonstrates the importance of screening after the diagnosis and treatment of lung carcinoma.

Abstract
STUDY OBJECTIVES To facilitate marking and to reduce its complications, we performed barium marking using an ultrathin bronchoscope with virtual bronchoscopic (VB) navigation before thoracoscopic surgery for small pulmonary peripheral lesions. We then evaluated the feasibility, safety, and efficacy of this technique. DESIGN A pilot study. SETTING A tertiary teaching hospital. PATIENTS The subjects were consecutive patients with small pulmonary peripheral lesions (ie, </= 10 mm) showing a CT scan-confirmed pure ground-glass opacity pattern between December 2001 and August 2003. INTERVENTIONS VB images to the planned marking sites near each lesion were produced from helical CT scan data. Based on these images, an ultrathin bronchoscope was advanced to the target bronchus under direct vision. Under CT scan and radiographic fluoroscopy, a catheter was inserted to the planned site via the bronchoscope, and barium sulfate suspension was instilled for marking. RESULTS The subjects were 23 patients (8 men and 15 women) who had a total of 31 lesions. The bronchial branching patterns seen in VB images were highly consistent with those confirmed using the ultrathin bronchoscope. Therefore, the ultrathin bronchoscope could be guided under direct vision to a median of the sixth generation bronchi (range, fourth to ninth generation bronchi) toward the planned marking sites. Marking was achieved without causing complications in any of the patients. The median marking time was 23.5 min, and the median shortest distance between the barium marker and the lesion was 4 mm (within 10 mm in 27 lesions). In patients undergoing thoracoscopic surgery, all barium-marked sites were identified by intraoperative radiographic fluoroscopy, and all lesions were resected. A pathologic examination demonstrated primary lung cancer in 17 lesions (bronchioloalveolar carcinoma, 15; adenocarcinoma, 2), atypical adenomatous hyperplasia in 12 lesions, and pneumonia in 2 lesions. CONCLUSIONS This method can be readily performed without complications and is a useful marking method before thoracoscopic surgery for small pulmonary peripheral lesions.

Abstract
The aim of this study was to assess the probability of malignancy in one or two small nodules 1 cm or less coexisting with potentially operable lung cancer (coexisting small nodules). The preoperative helical CT scans of 223 patients with lung cancer were retrospectively reviewed. The probability of malignancy of coexisting small nodules was evaluated based on nodule size, location, and clinical stage of the primary lung cancers. Seventy-one coexisting small nodules were found on conventional CT in 58 (26%) of 223 patients, and 14 (6%) patients had malignant nodules. Eighteen (25%) of such nodules were malignant. The probability of malignancy was not significantly different between two groups of nodules larger and smaller than 0.5 cm ( p=0.1). The probability of malignancy of such nodules within primary tumor lobe was significantly higher than that in the other lobes ( p<0.01). Metastatic nodules were significantly fewer in clinical stage-IA patients than in the patients with the other stage ( p<0.01); however, four (57%) of seven synchronous lung cancers were located in the non-primary tumor lobes in the clinical stage-I patients. Malignant coexisting small nodules are not infrequent, and such nodules in the non-primary tumor lobes should be carefully diagnosed.

Abstract
BACKGROUND With recent advances in low-dose helical computed tomography (CT), detection of ground-glass opacity (GGO) has increased. The aim of this study was to correlate high-resolution CT (HRCT) findings with pathologic features and to evaluate the efficacy of thoracoscopic limited resection for focal GGO, which were selected based on HRCT findings. METHODS Focal GGO lesions were classified into two subtypes based on HRCT findings: pure type and mixed type. Ninety-six patients with persistent GGO 2 cm or less in diameter underwent pulmonary resection from January 1997 to December 2001. Among these, thoracoscopic wedge resection was performed prospectively between June 2000 and December 2001 in 33 patients with pure GGO lesions that were 1 cm or less. RESULTS Thoracoscopic wedge resection was completed with complete safety. The histologic diagnoses of these 33 lesions were adenocarcinoma in 1, bronchioloalveolar carcinoma (BAC) in 23, and atypical adenomatous hyperplasia (AAH) in 9. No patients have had any evidence of tumor recurrence to date. Of the total 96 GGO lesions, 93.0% (53/57) of pure GGO 1 cm or less were BAC or AAH, whereas 38.5% (15/39) of pure GGO larger than 1 cm or mixed GGO were adenocarcinoma. CONCLUSIONS Pure GGO 1 cm or less was characteristic of noninvasive lesions. Thoracoscopic limited resection for small GGO lesions selected by HRCT was valid.

Abstract
BACKGROUND We reported that bronchioloalveolar adenocarcinoma (BAC) without active fibroblastic proliferation of the lung had no lymph node and pulmonary metastasis and had a favorable prognosis. However, there has been no prospective trial regarding limited pulmonary resection for this type of BAC. The purpose of this study is to confirm the effectiveness of limited resection for histologically confirmed BAC without active fibroblastic proliferation. METHODS From 1996 through 1999, 42 patients who had small peripheral lung tumors (< or = 20 mm), suspected of being BAC, were enrolled in this trial. The patient population consisted of 24 men and 18 women with a mean age of 58.4 years. Limited resection was completed when BAC, without both active fibroblastic proliferation and lymph node metastasis, was confirmed histologically by intraoperative pathologic examination. RESULTS Limited resection was completed in 36 patients, wedge resection in 34, and segmentectomy in 2 patients. In 6 patients, the procedure was converted into lobectomy because of pathologic invasive sign in 3, active fibroblastic proliferation in 1, and for other reasons in 2 patients. All patients have been followed for a median follow-up period of 30 months and are alive without sign of recurrence. CONCLUSIONS Our early results indicate that limited resection may be an acceptable alternative to lobectomy for histologically confirmed BAC without active fibroblastic proliferation.

Abstract
BACKGROUND Serum-soluble interleukin-2 receptor (IL-2R) concentrations have been found to be elevated in cancer patients. However, the importance of this finding in patients with non-small-cell lung cancer (NSCLC) has not been previously established. METHODS Preoperative serum-soluble IL-2R concentrations were determined in 65 consecutive patients with operable NSCLC. The correlation of preoperative serum-soluble IL-2R concentrations with various clinicopathological features of this cancer was evaluated to clarify the clinical significance of this parameter. RESULTS Although serum-soluble IL-2R concentrations were not significantly higher in operable NSCLC patients than in normal controls (P = .1180), serum-soluble IL-2R concentrations were significantly higher in patients with stage IIIB or IV disease than in normal controls (P = .0001). The presence of intrapulmonary metastasis was the only clinicopathological feature that was significantly correlated to serum-soluble IL-2R concentration (P = .0004). The sensitivity of serum-soluble IL-2R concentration in identifying the presence of intrapulmonary metastasis was 87.5%; specificity was 75%. CONCLUSIONS Elevated preoperative serum-soluble IL-2R concentrations in patients with operable NSCLC reflect the occurrence of intrapulmonary metastasis. Preoperative examination of serum-soluble IL-2R concentrations may be valuable in the detection of the intrapulmonary metastasis preoperatively.

Abstract
PURPOSE Bronchioloalveolar cell adenomas (BAAs) have been described in up to 10% of patients with bronchogenic carcinoma. Their prognostic significance is unknown. The purpose of this study was to determine the prognostic implications of finding BAAs coexisting in specimens resected for primary bronchogenic carcinoma and to determine how frequently BAAs can be detected radiologically. METHODS Follow-up information for a mean of 30 months was obtained on 28 patients with a single primary bronchogenic carcinoma and one or more coexistent BAAs. Preoperative chest radiographs (n=27) and CT scans (n=24) were retrospectively reviewed to assess the number of patients in whom BAAs could be detected radiologically. RESULTS There was no significant difference between percentage survival of patients with a primary bronchogenic carcinoma and coexistent BAAs when compared with the percentage predicted survival of these patients based on their primary bronchogenic carcinoma alone. BAAs could be detected retrospectively in 1 of 27 (4%) preoperative radiographs and 11 of 24 (46%) CT scans. CONCLUSIONS On standard preoperative imaging for bronchogenic carcinoma, BAAs were retrospectively detected in more than one third of patients in whom they were detected pathologically. However, the presence of coexistent BAAs with bronchogenic carcinoma does not affect short- and medium-term prognosis.

Abstract
We reviewed our experience with second primary lung cancer (SPLC) at the Little Rock Veterans Affairs Medical Center from 1966 to 1993. Fifty-four patients were found to have 65 such lesions after 1,572 "curative" resections for lung cancer (4.1%). Eleven patients had at least a third primary tumor (3 having more). Metachronous SPLCs comprised 60% (39/65) and synchronous 40% (26/65). The mean interval between first and second tumors was 54.63 +/- 8 (standard error) months (range, 5 to 218 months), and that between second and third was 26.1 +/- 7.4 (standard error) (range, 5.5 to 51 months). Squamous cell carcinoma comprised 58.4% (38/65), adenocarcinoma 30.8% (20/65), and small cell carcinoma 10.8% (7/65). Histology of the SPLC was the same as that of the first tumor in 50.7% (33/65). Stage I primary tumors comprised 76% (41/54) of index tumors, 61.1% (33/54) of SPLCs, and 72.2% (8/11) of third primary tumors. Second primary lung cancer followed minimal resection in 44% (24/54), lobectomy in 37% (20/54), and pneumonectomy in 13% (7/54) of cases. There was no evidence that minimal resection for the first primary tumor predisposed to SPLC. After 1983 the majority of SPLCs were diagnosed with computed tomographic scanning. After resection of SPLCs, survival rates at 3 and 5 years were 26% and 18%, metachronous 39% and 23.4%, and synchronous 12.25% and 12.25%.

Abstract
Three cases of second primary lung cancer following radiation therapy to the first pulmonary cancer were reported. In all cases, the first cancers located in the upper lobe and were unresectable diseases, their histologic type being epidermoid carcinoma. Radiation therapy was given with total doses of 60-70 Gy. Ten years later the second cancers arose in the contralateral lung and were treated with radiation therapy again.

Abstract
Synchronous primary lung cancers (SPLCs) occur in up to 0.5% of patients with lung cancer. They are first diagnosed intraoperatively or upon pathologic examination of resected tissue in up to 40% of patients with SPLCs. Complete surgical resection is possible in over 90% of patients, with an operative mortality of 2.1%. Despite a high frequency of early stage disease (two thirds of patients have either stage I or II tumors), surgical therapy yields an overall 5-year survival of only 20%, far lower than expected. These findings suggest that the biology of SPLCs is different from that of ordinary lung cancers, or that the diagnosis of SPLCs is being made too often, and that in some patients the second cancer focus actually represents metastatic disease. The use of newer techniques of identifying the molecular and biologic characteristics of these cancers, including analysis of DNA ploidy patterns, may more accurately define SPLC patients. Optimal interventional and preventive therapies remain to be determined.

Abstract
BACKGROUND The treatment of patients with multiple intrapulmonary lesions remains controversial. METHODS Fifty-three patients with lung cancer, in whom preoperative evaluation disclosed intrapulmonary nodules distinct from the main tumor, were analyzed retrospectively to establish the optimal treatment in such cases. RESULTS These sublesions proved to be intrapulmonary metastases (PM) in 16 cases (30%), multiple primary lung cancers in 7 cases (13%), and various nonmalignant lesions in the others. The survival of the 53 patients, and of patients with clinical Stage I/II disease in particular, compared favorably with that of all patients with resected lung cancer. Those with multiple sublesions had a poorer prognosis, irrespective of their nature. Although patients with PM as sublesions often had clinically advanced cancer, metastatic foci, per se, did not influence the survival data as calculated by a multivariate analysis. CONCLUSIONS The authors conclude that the existence of a solitary intrapulmonary sublesion should not preclude surgical treatment, unless surgery is contraindicated because of other clinical and radiologic findings.

Abstract
Two hundred forty-four veterans, with a mean age of 62.4 years, mainly asymptomatic (pulmonary), were admitted generally for other disease or pension evaluation and underwent lobectomy (131), segmentectomy (107), or wedge resection (6) for T1 N0 M0 lung cancer between 1966 and 1988. Conservative resection was preferred during the past decade. The average lesion diameter was 2 cm. Thirty-day mortality was 2.9%, similar for the three procedures. Absolute 5-year survival, 51%, was 78% if only deaths from the initial lesion are considered; 19% died of comorbidity, and 8% died of second lung cancers. Routine preoperative computed tomographic staging and intraoperative sampling of even normal-sized hilar and mediastinal nodes, conducted after 1982, improved survival (p less than 0.006). Patients with lesions less than 2 cm in diameter (146) did better (p less than 0.04), and those with squamous tumors improved similarly (p less than 0.02). Lesions that communicated with a bronchus (88) were more malignant than those (156) that did not (p less than 0.02), because from that locus undifferentiated nonsquamous tumors metastasized widely. These results suggest that the T1 N0 M0 category is not uniform. Histology, size, and location in the lung are significant variables. Results of conservative resection were similar or better than those of lobectomy. The latter was used more in deep-seated lesions, however, when major intersegmental planes were transgressed, and before modern preoperative and intraoperative staging. The T1 N0 M0 category should include lesions 2 cm or less in diameter as a discrete entity.
