Cox ML, Yang CFJ, Speicher PJ, Anderson KL, Fitch ZW, Gu L, Davis RP, Wang X, D'Amico TA, Hartwig MG, Harpole DH, Berry MF. The Role of Extent of Surgical Resection and Lymph Node Assessment for Clinical Stage I Pulmonary Lepidic Adenocarcinoma: An Analysis of 1991 Patients. J Thorac Oncol 2017; 12:689-696. [PMID: 28082103 DOI: 10.1016/j.jtho.2017.01.003] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2016] [Revised: 12/12/2016] [Accepted: 01/02/2017] [Indexed: 12/30/2022]
Abstract
BACKGROUND This study examined the association of extent of lung resection, pathologic nodal evaluation, and survival for patients with clinical stage I (cT1-2N0M0) adenocarcinoma with lepidic histologic features in the National Cancer Data Base. METHODS The association between extent of surgical resection and long-term survival for patients in the National Cancer Data Base with clinical stage I lepidic adenocarcinoma who underwent lobectomy or sublobar resection was evaluated using Kaplan-Meier and Cox proportional hazards regression analyses. RESULTS Of the 1991 patients with cT1-2N0M0 lepidic adenocarcinoma who met the study criteria, 1544 underwent lobectomy and 447 underwent sublobar resection. Patients treated with sublobar resection were older, more likely to be female, and had higher Charlson/Deyo comorbidity scores, but they had smaller tumors and lower T status. Of the patients treated with lobectomy, 6% (n = 92) were upstaged because of positive nodal disease, with a median of seven lymph nodes sampled (interquartile range 4-10). In an analysis of the entire cohort, lobectomy was associated with a significant survival advantage over sublobar resection in univariate analysis (median survival 9.2 versus 7.5 years, p = 0.022, 5-year survival 70.5% versus 67.8%) and after multivariable adjustment (hazard ratio = 0.81, 95% confidence interval: 0.68-0.95, p = 0.011). However, lobectomy was no longer independently associated with improved survival when compared with sublobar resection (hazard ratio = 0.99, 95% confidence interval: 0.77-1.27, p = 0.905) in a multivariable analysis of a subset of patients in which only those patients who had undergone a sublobar resection including lymph node sampling were compared with patients treated with lobectomy. CONCLUSIONS Surgeons treating patients with stage I lung adenocarcinoma with lepidic features should cautiously utilize sublobar resection rather than lobectomy, and they must always perform adequate pathologic lymph node evaluation.

Abstract
BACKGROUND Five-year survival rates for resected stage I adenocarcinoma approach 100%. Given previous studies describing the prolonged indolent natural history of ground-glass lesions suspicious for early adenocarcinoma, our purpose in this study was to determine if outcomes were different among patients who were observed for radiographic and biopsy suspected early adenocarcinoma compared with those who were resected immediately. METHODS We identified 63 patients with no prior history of lung adenocarcinoma who had undergone computer tomography-guided fine-needle aspiration of ground-glass opacities with cytology concerning for new early adenocarcinoma between January 2002 and December 2011. We compared the clinical outcomes of patients who were resected after abnormal cytology results and those who opted for watchful waiting. RESULTS Sixteen patients elected to observe their ground-glass nodules despite having suspicious cytology results, whereas 47 opted for immediate resection. Of the 16 observed patients, six (37.5%) ultimately demonstrated growth or increase solid component of the ground-glass nodule. Five of these patients elected for definitive therapy by surgical resection or radiation. There were no occurrences of distant metastasis or lung cancer-associated deaths in the observed group. Of the 47 resected patients, two developed metastatic disease, five developed new cancers in remaining lung, and three developed progression in existing ground-glass nodules. CONCLUSIONS Ground-glass lesions that were observed after biopsy did not demonstrate any increased rates of metastasis or cancer-related deaths and delayed resection does not seem to have a negative effect on outcomes.

Abstract
Pneumonic-type lung adenocarcinoma (P-ADC) represents a distinct subset of lung cancer with specific clinical, radiological, and pathological features. Given the weak association with tobacco-smoking and the striking similarities with jaagsiekte sheep retrovirus (JSRV)-induced ovine pulmonary adenocarcinoma, it has been suggested that a zoonotic viral agent infecting pulmonary cells may predispose to P-ADC in humans. Our objective was to explore whether exposure to domestic small ruminants may represent a risk factor for P-ADC. We performed a multicenter case-control study recruiting patients with P-ADC as cases and patients with non-P-ADC non-small cell lung cancer as controls. A dedicated 356-item questionnaire was built to evaluate exposure to livestock. A total of 44 cases and 132 controls were included. At multivariate analysis, P-ADC was significantly more associated with female gender (Odds-ratio (OR) = 3.23, 95% confidence interval (CI): 1.32–7.87, p = 0.010), never- smoker status (OR = 3.57, 95% CI: 1.27–10.00, p = 0.015), personal history of extra-thoracic cancer before P-ADC diagnosis (OR = 3.43, 95% CI: 1.10–10.72, p = 0.034), and professional exposure to goats (OR = 5.09, 95% CI: 1.05–24.69, p = 0.043), as compared to other subtypes of lung cancer. This case-control suggests a link between professional exposure to goats and P-ADC, and prompts for further epidemiological evaluation of potential environmental risk factors for P-ADC.

Abstract
A 73-year old healthy woman presented for pacemaker replacement. Chest X-ray showed an right upper lobe consolidation. CT-scan and bronchoscopy with bronchoalveolar lavage could not yield a specific diagnosis. Due to progression of the consolidation in a CT scan after 10 weeks another bronchoscopy with transbronchial biopsy was performed and yielded bronchiolo-alveolar carcinoma. The patient underwent resection of the right upper lobe and middle lobe with curative intent.

Abstract
Bronchoalveolar carcinoma (BAC) is a previously uncommon subset of non-small-cell lung cancer (NSCLC) with unique epidemiology, pathology, clinical features, and natural history compared with other NSCLC subtypes. Recent data indicate that the incidence of BAC is increasing. Although many studies have reported that patients with BAC have prolonged survival, advanced BAC remains incurable, with most patients eventually dying of respiratory failure from progressive pulmonary involvement or intercurrent illness. Previous limited data suggest that chemotherapy for BAC provides modest benefit; however, anecdotal reports of swift and durable responses after treatment with tyrosine kinase (TK) inhibitors of the epidermal growth factor receptor (EGFR) in patients with BAC have prompted further investigation in this subset of patients. Two trials using the EGFR TK inhibitors gefitinib and/or erlotinib have demonstrated encouraging results, and have prompted further enthusiasm for this approach. Furthermore, recent insights into mechanisms of drug sensitivity should impact future clinical trial design.

Abstract
PURPOSE To analyze diagnostic approaches, survival predictors, and treatment efficacy in pneumonic-type adenocarcinoma (P-ADC). PATIENTS AND METHODS Fifty-two patients with P-ADC diagnosed between January 1986 and December 2000 were studied. P-ADC was defined as histologically or cytologically proven pulmonary adenocarcinoma with a pneumonia-like consolidation, in a patient with no prior diagnosis of thoracic or extrathoracic adenocarcinoma. RESULTS Sixty percent of the patients were men (n = 31), and 65% (n = 34) were current or former smokers. Mean (+/- SD) age at diagnosis was 66 +/- 1.4 years. P-ADC was diagnosed by routine chest radiography in 17% of cases (n = 9). Bronchorrhea was present in 31% of cases (n = 16), and crepitant rales in 58% (n = 30). The primary tumor appeared as consolidations, which could not be assessed and were thus classified Tx, in 83% of the patients (n = 43). Ten percent of the patients (n = 5) had a satellite tumor within the lobe containing the primary tumor (T4), and 63% (n = 33) had a satellite tumor in another lobe (M1). Extrathoracic metastases were present in 5% of cases (n = 3). Bronchial biopsy, transbronchial biopsy, bronchial aspiration, and BAL were positive in 21%, 80%, 44%, and 66% of cases, respectively. The median survival time after diagnosis was 10.5 months (range, 1 to 150 months). The outcome of patients treated by lobectomy or bilobectomy was significantly better than that of patients treated with pneumonectomy, chemotherapy, or best supportive care (p < 0.01). Bronchorrhea and crepitant rales were independent predictors of shorter survival when the treatment modality (surgery vs no surgery) was not entered as a risk factor. CONCLUSIONS P-ADC is characterized by aerogenous propagation, as emphasized by the results of multivariate analysis showing that bronchorrhea and crepitant rales were the only two independent factors of shorter survival. Surgery remains the most effective treatment in P-ADC, especially when lobectomy is feasible. As CT is not sensitive enough to detect multifocal lesions, new tools are required to evaluate pulmonary involvement and thereby to refine the surgical strategy.

Abstract
BACKGROUND No effective therapy is currently available for the diffuse stage of bronchioloalveolar carcinoma. OBJECTIVE We tested the hypothesis that total lung replacement with standard lung transplantation techniques would provide curative therapy. METHODS Nine patients aged 31 to 58 years with bronchioloalveolar carcinoma were entered in the study. Five patients initially had bilateral diffuse tumor. Four patients had recurrence in the contralateral lung after pulmonary resection. RESULTS Between 1993 and 1998, all 9 patients underwent transplantation (2 single-lung and 7 bilateral transplants, 1 reoperative single-lung transplant, and 1 reoperative bilateral transplant). Two patients had mediastinal node metastasis (level 7) at the time of transplantation, and 1 of these had a frankly invasive adenocarcinoma. Of the 8 patients with pure bronchioloalveolar carcinoma, 6 had recurrent pulmonary tumor after transplantation. In 2 of these patients the tumor was localized and could be resected with left lower lobectomy in one case and left pneumonectomy in the other. One is alive 89 months after transplantation; the other died 82 months after transplantation. Four other patients had a diffuse pattern of pulmonary recurrence. Two died of progressive pulmonary failure; 1 of these had retransplantation with recurrence. A third patient died of cerebral edema shortly after bilateral retransplantation. The other patient is alive with recurrence 39 months after transplantation and has bronchiolitis obliterans. Two patients without recurrence are well with unrestricted performance levels 87 and 76 months after transplantation. CONCLUSIONS Transplantation produces a powerful palliative outcome in patients with advanced bronchioloalveolar carcinoma, but the recurrence rate is high. Transplantation for this indication remains controversial.

Abstract
BACKGROUND The histologic criteria defining bronchioloalveolar carcinoma (BAC) were recently revised, but it is unclear whether these criteria predict clinical behavior. This study determined the outcome of resected BAC in relationship to clinical and radiologic disease pattern, and pathologic features. METHODS Between 1989 and 2000, 100 consecutive surgically treated patients with adenocarcinomas exhibiting various degrees of BAC features were retrospectively studied. Histology was reviewed; tumors were classified as pure BAC, BAC with focal invasion, and adenocarcinoma with BAC features. Clinical and radiologic pattern were classified as unifocal, multifocal, or pneumonic. Demographic data, tumor stage, and outcome were recorded. Survival was analyzed by the Kaplan-Meier method, and prognostic factors were determined by the log-rank test. RESULTS Patient median age was 65, and 74% of the patients were female. Pure BAC, BAC with focal invasion, and adenocarcinoma with BAC features occurred in 47, 21, and 32 patients, respectively. Unifocal disease occurred in 64 patients, multifocal in 29, and pneumonic in 7. Seventy-one patients had stage I/II tumors, 22 had stage III/IV, and 7 patients had Stage X tumors. Overall 5-year survival was 74%. There was no significant difference in survival among the three histologic subtypes. The pneumonic pattern had significantly worse survival compared with unifocal and multifocal patterns. Pathologic stage predicted survival, with 5-year survivals for I/II and III/IV of 83.7% and 59.6%, respectively. CONCLUSIONS Clinical pattern and pathologic stage, but not the degree of invasion on histologic examination predict survival. Multifocal disease is associated with excellent long-term survival after resection. The favorable survival of stage III/IV BAC indicates that the current staging system does not fully describe this disease in patients undergoing resection because of its distinct tumor behavior.

Abstract
OBJECTIVE As bronchioloalveolar carcinoma (BAC) is noninvasive but, in its later stages, has a worse prognosis than adenocarcinoma with bronchioloalveolar features (ACB), early identification and differentiation is important for therapeutic and prognostic purposes. We wanted to identify features of BAC, which differentiated it from ACB when both presented as ground-glass opacities (GGOs) on CT. MATERIALS AND METHODS We reviewed all pathologic specimens of patients who were diagnosed with BAC and ACB in the lung from 1991 to 1999 in our institution and whose malignancy presented as a GGO on CT. This yielded 29 patients, 15 with BAC and 14 with ACB with GGOs on CT. Both univariate frequency table and multivariate logistic regression approaches were used to analyze the CT characteristics of these GGOs (location, GGO pattern, size, shape, margin, presence and type of air bronchogram and pseudocavitation). RESULTS BAC most frequently had a "GGO halo" around a solid opacity, often was a GGO "mixed with consolidation" with the smallest BACs being "pure GGO." Air bronchograms were frequently present in the largest GGOs. Pseudocavitations were rare. ACB, on the other hand, most frequently presented as a GGO "mixed with consolidation," less frequently with a "GGO halo" and rarely with "superimposed lymphangitis." The air bronchograms, frequently present, were usually tortuous and ectatic. Pseudocavitation was present in about one-third of the cases. The most useful CT features of GGO in separating those due to BAC from those due to ACB were pure (uniform) ground-glass attenuation and absence of lymphangitis. CONCLUSION The CT features of BAC and ACB presenting as GGO reflect the histologic descriptions of these carcinomas.

Abstract
OBJECTIVE Bronchioloalveolar lung carcinoma (BAC) is characterized by bronchial and lymphatic dissemination explaining multifocal and bilateral spreading. Bilateral BAC is usually considered as a contraindication to surgery. Regarding poor efficacy of symptomatic and oncological treatments, we hypothesized that surgery might play a role to palliate hypoxemia associated with serious intrapulmonary shunting, as well as continuous bronchorrhea. METHODS We retrospectively studied here four consecutive patients, who underwent palliative pneumonectomy. RESULTS The shunt was confirmed again at the time of the surgery by a pulmonary artery occlusion demonstrating immediate improvement in arterial oxygen saturation from 89% at baseline to 98% after occlusion. Lung resections consisted of a left pneumonectomy in three cases and a right pneumonectomy in one. PaO(2) levels under 5l/min oxygen therapy improved dramatically when comparing preoperative data (mean 50.5 mmHg) to post-operative results (mean 150 mmHg). One patient died postoperatively. Three patients, who experienced an uneventful immediate post-operative course, received chemotherapy after surgery. Improvement of quality of life is testified by the absence of both symptoms and any need for oxygen therapy for few months. Disabling symptoms reappeared at 1, 8 and 10 months. Survival of these patients was 3, 12 and 18 months. CONCLUSIONS These results support the interest of consideration of a surgical resection for highly selected patients presenting with bilateral BAC and severe intrapulmonary shunting.

Abstract
Studies on the molecular mechanisms of transformation of retrovirus-induced neoplasms in domestic and laboratory animal species have provided insights into the genetic basis of cancer. Ovine pulmonary adenocarcinoma (OPA) is a retrovirus-induced spontaneous lung tumor of sheep that has striking analogies to some forms of human adenocarcinoma. The etiologic agent of OPA, jaagsiekte sheep retrovirus (JSRV), is unique among retroviruses for having a specific tropism for the differentiated epithelial cells of the lung, and it is the only virus known to cause a naturally occurring lung adenocarcinoma. Expression of the JSRV envelope protein is sufficient to induce cell transformation in vitro, possibly via the activation of the phosphatidylinositol 3-kinase/Akt-signaling pathway mediated by the cytoplasmic tail of the transmembrane protein. The aim of this review is to draw the attention of basic and clinical scientists engaged in lung cancer research to this unique animal model, to explore the possible use of OPA as a tool to investigate the mechanisms of pulmonary carcinogenesis, and to underline the similarities between OPA and some forms of human lung adenocarcinoma. The possibility of a viral etiology for the latter will be evaluated in this review.

Abstract
OBJECTIVES The aim of our study was to retrospectively compare the patient characteristics, the frequency and pattern of recurrent disease, and survival in patients with stage I bronchioloalveolar carcinoma and adenocarcinoma of the lung. METHODS Patients with stage I bronchioloalveolar carcinoma or adenocarcinoma other than bronchioloalveolar carcinoma resected between 1984 and 1992 with adequate clinical follow-up were studied. The clinical characteristics of the patients, extent of initial surgical resection, sites of recurrent disease, and overall survival were examined and compared between the 2 groups. The median follow-up for patients with bronchioloalveolar carcinoma and adenocarcinoma was 6.2 years and 5.9 years, respectively. RESULTS A total of 138 patients were identified. Thirty-three patients had bronchioloalveolar carcinoma and 105 patients had adenocarcinoma. Eleven (33%) of the patients with bronchioloalveolar carcinoma had never smoked cigarettes versus 9 (9%) of the patients with adenocarcinoma (P =.0036). There were no significant differences between patients with bronchioloalveolar carcinoma and adenocarcinoma in sex distribution and overall recurrence rate. Of the 12 patients with recurrent bronchioloalveolar carcinoma, 1 patient (8%) had extrathoracic disease develop at the site of first recurrence compared with 49% of patients with recurrent adenocarcinoma (P <.001). The 5-year survival in patients with bronchioloalveolar carcinoma and in those with adenocarcinoma was 83% and 63%, respectively (P =.04). CONCLUSIONS Stage I bronchioloalveolar carcinoma is more likely to occur in nonsmokers. Survival is longer in patients with bronchioloalveolar carcinoma. Further research is warranted to define the etiology, clinical course, and molecular abnormalities in patients with bronchioloalveolar carcinoma to generate more effective therapeutic approaches.

Abstract
BACKGROUND The incidence of bronchioloalveolar carcinoma of the lung (BAC), a pathologically distinct type of nonsmall cell lung carcinoma (NSCLC), appears to be rising. In this study, the authors compared data on the clinical presentation and clinical courses of patients with Stage IIIB and IV BAC with data on other types of NSCLC. METHODS The authors collected clinical, radiographic, and pathology information about 28 patients with Stage IIIB and IV BAC and 124 patients with other histologic types of NSCLC. RESULTS Twelve of 28 BAC patients (43%) were women, compared with 40 of 124 control patients (32%). Nine (32%) of the patients with BAC had never smoked cigarettes, versus 20 controls (16%) (P = 0.02). Eighteen patients (64%) with BAC had bilateral multilobar or multicentric pulmonary involvement, compared with 13 controls (15%) (P < 0.001). Patients with advanced stage (IIIB and IV) BAC had a median survival of 15 months from the time of diagnosis; for patients with other types of Stage IIIB and IV NSCLC, had a median survival of 10 months (P = 0.01). CONCLUSIONS Patients with BAC of the lung have clinical, radiographic, and pathologic characteristics that distinguish them from patients with other types of NSCLC. A greater proportion of women and nonsmokers present with BAC than with other types of NSCLC. Patients with advanced stage BAC are more likely to have bilateral diffuse pulmonary involvement, are less likely to develop brain metastases, and have longer survival than patients with other types of Stage IIIB and IV NSCLC. Further research is warranted to define etiology, molecular abnormalities, and more effective therapeutic interventions.

Abstract
BACKGROUND The principal feature of bronchoalveolar carcinoma is that it spreads along airways or aerogenously with multifocality, but many issues are unresolved. METHODS We studied 119 patients with pathologically confirmed bronchoalveolar carcinoma. Symptoms, smoking status, radiologic findings, the size of tumor, operative procedures, and complications were reviewed. We studied the pathologic features: presence or absence of aerogenous spread, patterns of growth, cell type, nuclear grade, mitosis, rate of bronchoalveolar carcinoma in adenocarcinoma, and lymphocyte infiltration. The correlation among clinical, radiologic, and pathologic findings was examined, and the factors affecting survival were analyzed. RESULTS Symptomatic patients had more infiltrative radiographic features, and asymptomatic patients tended to have more mass-like features (P <.0001). Tumors with radiographically infiltrating lesions tended to have mucinous histologic features (P =.006). Tumors with mass lesions by radiograph tended to have nonmucinous and sclerosing histologic features (P =.003). Aerogenous spread was seen in 94% of specimens. The presence of a variety of cell types suggested multiple clonal origin. The overall survival in those patients undergoing resection was 69.1% at 5 years and 56.5% at 10 years. The significant factors affecting survival were radiologic presence of a mass or infiltrate, pathologic findings of the presence of sclerosis, association with a scar, the rate of bronchoalveolar carcinoma in adenocarcinoma, lymphocyte infiltration grade, nodal involvement, and status of complete resection. Mitosis or nuclear grade of tumor cells did not correlate with survival. CONCLUSIONS Bronchoalveolar carcinoma showed good overall survival with appropriate surgical procedures. Certain radiologic or pathologic findings correlated with survival. These findings may enhance the ability to predict long-term survival.

Abstract
STUDY DESIGN To determine the long-term results after surgical treatment of bronchioloalveolar lung carcinoma (BALC) and to identify prognostic factors. PATIENTS AND METHODS A retrospective study of 70 patients (49 men, 21 women), mean age 61+/-10 years, was carried out. Their carcinomas were classified into three clinicopathologic types: nodular or tumoral, pneumonic, and diffuse types. All the diagnosed BALC cases were reviewed and were classified into histologic types: mucinous, nonmucinous (including fibrotic center), and mixed tumors. Univariate and multivariate analyses were carried out. RESULTS The nodular or tumoral type was identified in 42 patients, pneumonic in 21, and diffuse in seven. Histologically, there were 36 mucinous, 25 nonmucinous, and nine mixed tumors. Resection was complete in 61 instances (87%) and incomplete in five. The 5-year survival rate was 34% in patients with curative resections. Five prognostic factors were identified by univariate analysis, but in multivariate analysis, only three factors remained significant: the absence of symptoms, the TNM stage, and completeness of resection. Thirty-six patients with curative resection (59%) developed recurrences (in the lung in 26 patients; mediastinal lymph nodes, four; distant metastases, nine). The frequency of recurrence was significantly greater in patients with pneumonic-type BALC than in nodular or tumoral types (p<0.01), and pulmonary recurrences were significantly more frequent in pneumonic than in tumoral types (p<0.02). CONCLUSIONS This study confirmed that the overall prognosis of BALC is not significantly different from that of the other non-small cell lung cancers. We found that the lungs are the predominant site of recurrence in BALC, especially in the pneumonic types. The complete surgical resection of localized BALC offers the best chances of long-term survival.

Abstract
Primary pulmonary tumors are infrequent in children. Bronchioloalveolar carcinoma has been documented rarely in the pediatric population. Before this report, there have been only three cases of bronchioloalveolar carcinoma in patients less than 16 years of age. Our two cases represent two of the youngest cases (ages 6 and 15 years) reported with bronchioloalveolar carcinoma. They illustrate many of the typical findings of this disease including clinical presentation, diagnostic difficulty, and better prognosis compared with other pulmonary malignancies. This neoplasm appears to have a favorable outcome in childhood.

Abstract
There continues to be confusion as to whether papillary adenocarcinoma (PA) of the lung is a specific histologic entity or simply a variant of bronchioloalveolar carcinoma (BAC). We reviewed our files from 1981 through 1993 for all cases (n = 155) of resected primary lung adenocarcinoma specifically diagnosed as having papillary or bronchioloalveolar features. In addition, a random 10% (n = 67) of all remaining lung adenocarcinomas were reviewed. True PA was diagnosed when > or = 75% of the neoplasm contained papillary structures supported by fibrovascular cores with complicated secondary and tertiary branches. Marked nuclear atypia was present in 100%, and psammoma bodies were seen in 42% of cases. In contrast to BAC, true PA filled and distorted or replaced air spaces in the lung. Thirty-one cases of true PA were found, including 19 men and 12 women (mean age, 64.5 years). The lesions were solitary (n = 27) or multifocal (n = 4) with a mean diameter of 4.1 cm. Forty-five percent of patients had bronchopulmonary lymph node involvement at diagnosis; another 10% had extensive intrapulmonary lymphatic permeation by tumor. Disease-free survival for stage I and II PA was 40% (n = 15) and 25% (n = 8), respectively, at a mean of 3.4 and 3.5 years. Papillary adenocarcinoma of the lung is a distinct clinicopathologic entity with considerably worse morbidity and mortality than BAC.

Abstract
Bronchioloalveolar carcinoma is a subtype of adenocarcinoma of the lung with a relatively better prognosis. We reviewed the cases of 50 consecutive patients with bronchioloalveolar carcinoma treated during a 10-year period and attempted to analyze factors related to prognosis. During the 10-year study period, the prevalence of bronchioloalveolar carcinoma relative to adenocarcinoma of the lung remained steady. The subjects included 32 male and 18 female patients with mean ages of 64.7 years and 55.1 years, respectively (p = 0.0030). The preoperative radiographic findings included 40 cases of localized and 10 cases of diffuse bronchioloalveolar carcinoma. The clinicopathologic TNM staging included 20 patients with stage I cancer, 4 with stage II cancer, 11 with stage IIIa cancer, 3 with stage IIIb cancer, and 12 with stage IV cancer. Forty patients with clinical stage I, II, or III disease underwent operation (operability 80%). The resectability rate was 90% (36 of 40). Thirty-four procedures were considered as curative. The overall cumulative survival at 5 years was 22.2% (46.4% for stage I). Different TNM stages showed significant differences in survival time (p = 0.0001). The median survival times were 64.6 months for stage I, 48.0 months for stage II, 24.7 months for stage IIIa, 9.0 months for stage IIIb, and 4.5 months for stage IV disease. The median survival time for localized bronchioloalveolar carcinoma was 27.5 months, and the median survival time for diffuse bronchioloalveolar carcinoma was 4.3 months (p = 0.0002). The median survival time for the curative resection group was 30.6 months, and the median survival time for the noncurative resection or nonresection group was 5.8 months (p = 0.0001). On the basis of this study we conclude that (1) the prevalence of bronchioloalveolar carcinoma is quite steady, (2) bronchioloalveolar carcinoma presents at an earlier age in women, (3) bronchioloalveolar carcinoma frequently presents with lymphatic spread or systemic metastasis at diagnosis, (4) most localized bronchioloalveolar carcinomas are resectable and the prognosis with this type is better than that of the diffuse type, and (5) long-term survival correlates closely with initial roentgenographic appearance, TNM stage, and completeness of surgical resection.

Abstract
The solitary pulmonary nodule (SPN), a single intrapulmonary spherical lesion that is fairly well circumscribed, is a common clinical problem. About half of SPNs seen in clinical practice are malignant, usually bronchogenic carcinomas. Some nodules are primary tumors of other kinds or metastatic. Virtually all benign SPNs are tuberculous or fungal granulomas. The standard management of the SPN of unknown cause is prompt surgical removal unless benignity is established by prior chest roentgenograms showing that the nodule has been stable (i.e., showing no growth) for 2 years or by the presence of a "benign" pattern of calcification. Less universally accepted criteria for benignity include (1) transthoracic needle aspiration biopsy (TNAB) showing a specific benign process, and (2) patient's age under 30 to 35 years. Bronchoscopy has a low diagnostic yield, particularly for benign nodules. SPNs usually grow at constant rates, expressed as the "doubling time" (DT). A nodule with a DT between 20 and 400 days is usually malignant. Benign nodules usually have a DT greater than 400 days. The prospective determination of DT by serial chest roentgenograms (the "wait and watch" strategy) is widely criticized but has clinical utility in special circumstances, particularly if the likelihood of malignancy is low and/or the anticipated surgical mortality is high. The presence and pattern of calcification are best shown by high-resolution thin-section computed tomography (CT). Diffuse, laminated, central or "popcorn" patterns of calcification indicate benignity. An eccentric calcium deposit or a stippled pattern does not rule out malignancy. CT densitometry will often show "occult" calcification in nodules that show no direct visual evidence of calcium deposition. The characteristics of the edge of the nodule correlate with the likelihood of malignancy. Nodules with irregular or spiculated margins are almost always malignant. The probability that the nodule is malignant (pCA) is related to the age of the patient, the diameter of the nodule, the amount of tobacco smoke inhalation, the overall prevalence of malignancy in SPNs, the nature of the edge of the lesion, and the presence or absence of occult calcification. It is possible by Bayesian techniques to combine these factors to calculate a more precise and comprehensive prediction of pCA in any given nodule. The 5-year survival after nodule resection depends on the size of the nodule at the time of surgery; it may be as high as 80% with nodules that are 1 cm in diameter. Lymph node involvement is uncommon with small tumors, and many authorities question the need for CT staging in such cases.(ABSTRACT TRUNCATED AT 400 WORDS)
