Alterations in extracellular matrix, cell-cell and cell-matrix adhesion, and oncogenes are thought to be important in tumor progression and metastasis. Adenocarcinomas of the lung from 31 patients were studied for immunohistochemical expression of basement membrane molecule type IV collagen, type IV collagenase, and integrins alpha2,3,v adhesion molecules to assess their diagnostic and prognostic importance in pathological stage T2 tumors. The results indicate that with decreasing tumor differentiation, there is a progressive loss of type IV basement membrane collagen (P = .06) and decreased integrin alpha2 expression (P = .03). Type IV collagenase expression was significantly associated with the presence of lymph node metastases, with moderate to strong expression present in 53% T2N1 tumors compared with none (0%) of the T2N0 tumors (P = .008). Integrin alpha(v) was increased in tumors with nodal metastases compared with those without (P = .08). Loss of alpha2 and alpha3 integrins was associated with increased alpha v expression (P = .03). Median survival was 48 months for T2N0 and 20 months for T2N1 (P = .07). In correlating expression of the immunohistochemical markers and survival, type IV collagenase expression was found to be a predictor of survival at a level of P = .07. Measurable alterations in integrins and extracellular matrix, and in particular, expression of matrix-degrading enzyme type IV collagenase may be of prognostic importance in resectable adenocarcinoma of the lung.

An 80-year-old woman was admitted to the hospital because of a nodular lesion in the right upper lobe of the lung. Transbronchial biopsy was performed and adenocarcinoma of the lung was confirmed by pathological examination. The tumor was resected by right upper lobectomy and was found to be a moderately differentiated tubular adenocarcinoma. Numerous non-caseating epithelioid cell granulomas were also found intermingled with the cancer cells. Metastasis was apparent in several regional lymph nodes but no granulomatous lesions were found in any lymph node, regardless of metastasis. These findings were compatible with a "sarcoid-like reaction" because there was no clinical evidence of generalized sarcoidosis or pulmonary mycobacterial infection. Although sarcoid-like reactions are occasionally associated with cancer, formation of an epithelioid cell granuloma inside the primary tumor is very rare. All the reported cases of a sarcoid-like reaction within the primary lung tumor so far were with adenocarcinoma. The sarcoid-like reaction may be a local immune response to the cancer cells.

In order to clarify the morphological and biological characteristics of well differentiated adenocarcinoma of the lung predominantly composed of goblet cells (WDAG), histopathological examinations, including some molecular biological procedures, were carried out using 42 surgical specimens of primary lung carcinoma which were predominantly (>50% of the total cell population) or totally composed of goblet cells. The subjects included 19 men and 21 women, ranging in age from 41 to 81 (mean 60 years old) with predominantly nodular, peripherally located lesions. Ultrastructural examination revealed characteristic apical microvillous filamentous core rootless (AFCR) in some, but not all, cases. Histologically, these AFCR corresponded well with structures stained by phosphotungstic acid hematoxylin (PTAH). The goblet cells of WDAG were divided into PTAH-positive (26 cases) and -negative (16 cases) groups. The PTAH-positive group had larger tumor size, greater number of intrapulmonary and extrapulmonary metastases and shorter disease-free interval. The immunoexpression of p53 protein (60%) and rate of K-ras point mutation (84%) were also higher in the PTAH-positive group. Therefore the goblet cell population of WDAG, though it may appear morphologically homogeneous under light microscopy, is actually composed of heterogeneous groups of cells with different histopathological characteristics and biological behavior.

A case report of stage I adenocarcinoma of the lung in a 43-year-old female with recurrence in the small bowel and liver 11 months after pneumonectomy is presented. In addition, a cohort of 733 patients with non-small cell lung cancer (NSCLC) in all pretreatment stages (stages I-IV) with a total of 218 autopsies are evaluated, and the literature on the topic is reviewed, in order to define the frequency of metastases from NSCLC to the small bowel. There were 10 cases with and 208 cases without small bowel involvement among 218 consecutive autopsies (autopsy rate, 30%,). The frequency of small bowel involvement was 4.6% (95%, confidence interval, 2.2-8.3%), and all were in patients with adenocarcinoma of the lung. All patients with small bowel involvement at autopsy had also other concurrent metastatic sites as well and the following were the most frequent: adrenals (90%, of cases), mediastinal lymph nodes (80%), liver (70%), pleura (60%), contralateral lung (60%), bones (60%), and brain (50%). Significantly more metastatic sites were observed in patients with than without small bowel involvement, both totally (P = 0.0001) and with respect to number of extrathoracic (P = 0.0001) and intrathoracic (P = 0.01) metastatic sites. In conclusion, small bowel involvement in NSCLC is relatively infrequent. As a unique finding, over-representation of patients with poorly differentiated tumors (P = 0.03) and patients having solid carcinoma with mucus formation after histologic subtyping (P = 0.04) among cases with small bowel involvement was observed. This indicates, that small bowel metastases is an epiphenomonen of NSCLC tumors with certain biological characteristics, although as yet undiscovered, which leads to a high metastatic potential. If such biological characteristics could be identified, they may be used in the selection of treatment options for individual patients, e.g. indicating a need for adjuvant or neoadjuvant chemotherapy in addition to surgery in resectable or marginally resectable NCSLC patients.

When diagnosed as primary lung cancer, metastases from the abdomen, plus false negative cases have little effect on epidemiology studies of male smokers, but may result in a severe dilution of the lung cancers among women and nonsmokers. We have attempted to quantitate this handicap for epidemiological studies using two approaches. The relative frequency of diagnosed primary lung and abdominal cancer among males, women, and nonsmokers differs substantially and is used here to calculate magnitude. The second approach postulates that the ratio of nonsmokers among persons with squamous cell lung cancer and primary adenocarcinoma of the lung would be constant by sex if there were no distortion by abdominal metastases. These two approaches indicate that the much higher ratio of metastatic disease diagnosed as primary lung cancer among nonsmoking women (factor of 15 to 20), makes it more difficult to identify an environmental carcinogen among women or nonsmokers than among male smokers in case-control studies.

Haematogenous skeletal muscle metastases from non-small-cell lung cancer (NSCLC) are rare, and are even more uncommonly observed bilaterally. Usually, NSCLC metastasizes to the liver, adrenal glands, lung, bone, central nervous system and kidney. We report a case of a long-surviving patient with contemporaneous histologically proven bilateral muscle metastases in the right and left forearm triceps, from adenocarcinoma of the lung.

Cardiac metastases are uncommon and difficult to diagnose clinically; thus, they are most often found only at autopsy. Here we present a case of isolated right atrial cardiac metastasis found 7 weeks after the resection of the primary tumor, which was an adenocarcinoma of the lung. The patient presented with intractable obstructive shock, caused by a ball-valve effect of the atrial lesion that prevented forward blood flow from the right atrium. Computed tomography (CT) scans and echocardiograms failed to detect the lesion, and the patient died 2 weeks later. An autopsy revealed a large, isolated right atrial metastatic adenocarcinoma.

The patient was a 60-year-old female with adenocarcinoma of the lung. An effective radiation therapy was performed for cervical lymph node metastases found 19 months after the operation. A right adrenal metastasis and abdominal paraaortic lymph node metastases were detected 11 months later, and chemotherapy with cisplatin (CDDP) was administered. Although a temporary partial response was obtained, the metastatic lesion was refractory to CDDP. The patient was treated with gemcitabine (GEM) and CDDP, which resulted in near complete response continued for 3 months. The combination therapy of GEM and CDDP may be effective for recurrent non-small-cell lung cancer refractory to other regimens.

Clinical, gross pathology, histopathology and electron microscopy of the ovine pulmonary adenocarcinoma (OPA, jaagsiekte) either natural or experimentally induced in sheep, goat and moufflon are described. OPA is caused by an oncogenic betaretrovirus,jaagsiekte sheep retrovirus (JSRV). Most natural cases of OPA appear in animals 1-4 years old. There is no evidence of sex or breed susceptibility. Sheep affected by OPA show an afebrile respiratory illness associated with loss of weight. A very characteristic clinical sign is moist rales caused by the accumulation of fluid in the respiratory airways which is discharged from the nostrils when the head is lowered. Gross lesions are confined to the lungs but occasionally thoracic or extrathoracic structures are also affected. Two pathologic forms of OPA are currently recognized, classical and atypical. In classical forms the neoplastic lesions occurs particularly in the cranioventral parts of all lung lobes. They are diffuse or nodular, light grey or light purple in colour. On the cut surface the tumour is moist, and frothy fluid may pour from the airways on slight pressure. Atypical forms tend to be more nodular in both early and advanced tumours. They are pearly white in colour, very hard in consistency, very well demarcated from the surrounding parenchyma and their surface is dry. Histology of the lung sections reveals the presence of several foci of epithelial cell neoplastic proliferation in both alveolar or bronchiolar regions. The tumours, derived from type II pneumocytes and Clara cells, proliferate into mostly papillary but also acinar or occasionally solid growths. The tumour generally shows a benign histological pattern but intra- and extrathoracic metastases have been detected in some cases. Several considerations suggest that the tumour should be classified as an adenocarcinoma of the lung. The histology of atypical OPA is similar to that of the classical disease, with an increase in the stromal reaction accompanying the epithelial proliferations. Pathological features of OPA induced experimentally in sheep, or of OPA in goats and moufflon are similar to those described in sheep. Detailed electron microscopy of tumour material confirms that type II pneumocytes and Clara bronchiolar epithelial cells are the origin of the neoplasia. Also included in this chapter is a description of the morphology of the viral particles associated with OPA.

We describe a patient with adenocarcinoma of the lung who developed hydronephrosis secondary to compression by right common iliac lymph node metastases. The most common primary sites of cancers causing ureteral obstruction are the cervix, prostate, bladder and colo-rectum. To date, few reports of ureteral obstruction attributable to lung cancer have been published. Although rare, physicians should be aware that hydronephrosis can complicate the course of patients with non-small cell lung cancer.
