Abstract. In this communication, we will present a very rare case of the coexistence of non-Hodgkin's lymphoma (NHL; low malignant lymphocytic lymphoma of the B-cell type) and a non-small-cell lung carcinoma (NSCLC). A patient with a 15-year history of NHL developed a generalized relapse of the lymphoma with an additional tumor mass in the left lower lobe of the lung. Bronchoscopy showed the evidence of the NHL. Due to non-responding chemotherapy on the lung tumor, the coexistence of a second malignancy was histologically proved in a second bronchoscopy. Resection of the lung tumor with complex lobectomy and lymphadenectomy was performed. After that, chemotherapy with four cycles of carboplatin supplemented with taxol was induced. The patient was discharged from the hospital with a stable remission of both tumor diseases. Restaging after six months showed no evidence of a tumor relapse. This is a very rare case of the coexistence of NHL and NSCLC; we will discuss the difficulty of diagnostic and treatment of both tumor diseases.

The role of sex hormones in the pathogenesis of lung cancer is still unknown. There are conflicting results regarding immunohistochemical detection of the estrogen and progesterone receptors expression in non small cell lung cancer. To clarify these discrepancies 32 samples of lung carcinoma tissues obtained by lobectomy or pneumonectomy were studied. Two monoclonal antibodies (6F11 and ID5) for estrogen receptor detection and one (1A6) for progesterone receptor detection were used. Eighteen adenocarcinoma and 14 squamous cell carcinoma cases were investigated. There were 11 women and 7 men with adenocarcinoma and 4 women and 10 men with squamous cell carcinoma. Weak (+1) nuclear estrogen hormone receptor expression was detected in only one specimen of a woman with adenocarcinoma and in one specimen of a man with squamous cancer. None of the 32 blocks of paraffin embedded specimens expressed progesterone receptor. The positive estrogen and progesterone receptors expression in cancer tissue is an important argument against the pulmonary origin of the unknown primary tumor.

A 57-year-old Caucasian woman presented with nonproductive cough. Computed tomography revealed a peripheral solid mass in the upper lobe of the left lung. She underwent thoracotomy and upper lobectomy. Histology of the excised tumor demonstrated lymphoepithelioma-like carcinoma of the lung, with no associated Epstein-Barr virus activity. Being a rare entity and mostly seen in Asians, very few cases have been described previously.

Early hilar lung cancer is rare. It is usually curable if properly diagnosed and treated. We recently encountered two cases of early stage squamous cell carcinoma of the left upper division bronchus, which responded well to left upper division sleeve segmentectomy. Case 1 was a 74-year-old man, a heavy smoker, who was referred to our hospital after sputum cytology had resulted in a positive diagnosis while receiving inpatient care for heart failure at another hospital. Bronchoscopy revealed a thickened tumor at the spur between left B(1+2) and B(3). Squamous cell carcinoma was diagnosed by forceps biopsy via bronchoscopy. Left upper division sleeve segmentectomy with lymph node dissection was performed. Since the bronchi to be anastomosed to each other were greatly different in diameter, telescoped anastomosis was used. His postoperative course was uneventful, and he continues to show good respiratory condition, without any evidence of recurrence 25 months after surgery. Case 2 was a 60-year-old man, a heavy smoker, who was identified by sputum cytology as needing detailed examination during a mass screening of high-risk groups for early detection of lung carcinoma. Bronchoscopy revealed a nodular tumor at the orifice of the left upper division bronchus. Squamous cell carcinoma was diagnosed by forceps biopsy via bronchoscopy. Left upper division sleeve segmentectomy with lymph node dissection was performed. During surgery for this case, the lingular bronchus was dissected obliquely to make its cross-section wide enough to match the diameter of the left upper lobe bronchus to which the former was anastomosed. His postoperative course was uneventful, and he shows good respiratory condition, without any evidence of recurrence five months after surgery. The pathological stage was TisN0M0 (stage 0) in both patients, and their tumors were confirmed as early hilar lung cancer. Sleeve segmentectomy, aimed at radical resection of cancer while preserving lung function, can serve as a standard procedure for surgical treatment of cases of early hilar lung cancer confined to the segmental bronchi.

On computerized tomography (CT) screening for lung cancer within the Early Lung Cancer Action Project, both at baseline and repeat screening, we found not only solid but also subsolid nodules, which unlike solid ones do not completely obscure the lung parenchyma. We established that subsolid nodules represent approximately 20% of the nodules shown on screening and that they have a higher frequency of malignancy than solid nodules. Although we found growth of solid nodules to be a reliable indicator of malignancy, growth of subsolid nodules was more difficult to assess. On review of our results to date in screening, we have continued to refine our definition of a positive result of screening from that given in our initial publication on screening. We have also provided an updated screening regimen. It starts with the initial, low-dose CT test and for all those with positive results on this initial test, the regimen continues by specifying the work-up needed to rule-in a diagnosis of malignancy. In this regimen, we found growth assessed by high-resolution CT to be a useful indicator of malignancy and have developed image-processing tools to help in this assessment. Once growth is ascertained, we recommend fine-needle aspiration for confirmation of malignancy. It may be that once criteria for definitive growth are established and validated, fine-needle aspiration may become optional. However, in the meantime, in the context of screening, a more cautious approach is warranted.

Cardiac tumors, benign or malignant, are rare and most are benign. The most common benign tumor is the cardiac myxoma. Malignant cardiac tumors are usually sarcomas. The pericardium can be the site of benign and malignant cardiac tumors, though metastatic tumors occur here far more commonly than do primary tumors. Successful treatment for benign cardiac tumors is usually achieved by surgical resection. Surgery for primary malignant tumors is, however, much less successful as complete resection is usually not possible. Primary cardiac lymphoma may be successfully treated by chemotherapy. Tumors that metastasize to the heart from other organs occur 100- to 1000-fold more commonly than primary cardiac tumors. Metastatic spread to the heart has been identified in approximately one-fifth of all patients who have metastatic cancer with lung carcinoma being the most common primary tumor. Symptoms of cardiac metastases vary, and they depend on the site and extent of the lesions. Treatment varies depending on the pathology of the primary tumor. However, the aim of treatment is usually symptomatic relief. With the advent of AIDS, Kaposi's sarcoma and high grade B cell lymphomas have also been identified in cardiac tissue. The aim of this article is to review the epidemiology, clinical presentation, pathology and treatment of cardiac tumors.

We herein report a case of metastasis to the thyroid from lung adenocarcinoma mimicking thyroid carcinoma. The thyroid tumor was palpated in the left lobe of the thyroid and diagnosed as primary thyroid carcinoma by fine-needle aspiration cytology. The patient also had a large pulmonary tumor and tiny pulmonary nodules, which were respectively diagnosed as moderately differentiated adenocarcinoma of the lung and intrapulmonary metastases from the main large lung carcinoma by the pathological examination of the biopsy specimens obtained by video-assisted thoracic surgery. Hemithyroidectomy with radical neck dissection was performed. The thyroid tumor was diagnosed as metastasis to the thyroid from lung adenocarcinoma, because it showed mucin production, positive immunoreactivity for carcinoembryonic antigen and negative immunoreactivities for thyroglobulin and calcitonin. The patient received systemic chemotherapy and died of the disease 1 year and 7 months after the diagnosis was made.

We report a case of combined large cell neuroendocrine carcinoma. A 78-year-old man with vertigo was referred to our hospital where chest X-ray revealed a tumor shadow in the right lung. A transbronchial lung biopsy specimen verified a diagnosis of non-small cell lung carcinoma (cT1N0M0). Right lower lobectomy with mediastinal lymph node dissection (#7, 8, 9) was performed. A postoperative histological diagnosis was combined large cell neuroendocrine carcinoma of a component of squamous cell carcinoma [pT4 (pm) N2M0]. The patient received concurrent chemoradiotherapy due to upper mediastinal lymph node metastasis 4 months after surgery. The chemoradiotherapy well responded and the patient remains well 9 months after surgery.

It has been widely recognized that the oft-quoted randomized clinical trials (RCTs) of lung cancer screening by chest radiography--studies that were interpreted as showing no benefit--were seriously flawed. We begin by describing the shortcomings of these trials and presenting an analysis of the problems typically encountered in performing RCTs in this area. Screening for lung cancer using computed tomography (CT) has shown that CT offers great superiority over chest radiography in diagnosing small lung cancers in the three studies that performed both CT and chest radiography on all patients. The Early Lung Cancer Action Project (ELCAP), showed that false-positive results can be kept reasonably low and are much less common on repeat screening, and that CT screening can be managed with no notable excess of percutaneous or surgical biopsies when following a well-defined regimen of screening. This regimen details the parameters of the initial CT, the definition of a positive result, and the subsequent work-up of positive results. Following the updated International (I)-ELCAP protocol, it has been further found that (1) the frequency of positive results is low: 15% for the baseline cycle of screening and 6% for the subsequent cycles. (2) The frequency of screen-diagnoses as compared with all diagnoses is 97% or higher. (3) The relative frequency of presurgical Stage I is well over 80%; the median diameter of the screen-diagnosed cases on repeat screening is 8 mm (versus 15 mm at baseline screening). (4) A high percentage of the screen-diagnosed cases were genuine cancers which led to death if not treated. (5) The estimated 8-year cure rate for resected baseline screen-diagnosed lung cancers without evidence of lymph node metastases is 95% and for resected annual repeat cancers is 98%. (6) CT screening appears to be highly cost-effective. These preliminary results of CT screening suggests that the cure rate of screen-diagnosed lung cancer, using the I-ELCAP regimen of screening, may be over 70% as compared with that of usual care of 10% and that of chest radiographic screening of 20%.

The purpose of this study was to determine the clinical patterns, short- and long-term survival in elderly patients after surgery for non-small cell lung carcinoma. The 273 patients aged over 70 years who underwent curative resection from 1986 to 2001 were retrospectively assessed. Mean age was 73.2+/-3.1 years, (11% were>80 years). The mean follow-up was 31 months. Standard procedures were used: 151 lobectomies, 49 bilateral lobectomies, 42 pneumonectomies, 9 sleeve resections, and 22 wedge resections. The 30-day mortality was 5.4%. Multivariate analysis showed that extended procedures, male sex, and age were predictors of mortality. Overall survival rates at 5, 10, and 15 years were 35.6%, 10.5%, and 2.5%, respectively. Advanced disease stage, low forced expiratory volume in 1 second, and previous cardiac disease were independent predictors that adversely influenced survival. Geriatric patients with non-small cell lung carcinoma can undergo resection safely with acceptable long-term survival. Lobectomy is the procedure of choice, extended resections should only be carried out in highly selected patients. Careful attention to preoperative clinical staging is important as the elderly beyond the early stage of disease fare poorly. Surgery is justified for the treatment of stage I-II lung cancer.
