The results of treatment and the survival time of lung cancer patients are strictly dependent on early diagnosis. Fiberoptic bronchoscopy and bronchoalveolar lavage (BAL) are the most effective diagnostic methods in cancer diagnosis. These methods allowed us to evaluate biological neoplastic markers at the site of the tumor. Using commercially available ELISA kits (Endogen) followed by ETI-system (SORIN) analysis we measured the IL-2 concentration in BALF of 36 non-small cell lung cancer (NSCLC) patients before (Gr. I) and after (Gr. II) surgery and 18 non-neoplastic lung disorder patients as a control group (6 cases of sarcoidosis and 12 cases of COPD). In BALF of Gr. I Macrophage percentage was higher (x = 74.125%), and lymphocyte percentage was lower (x = 15.875%) than in sarcoidosis x = 38.33% and x = 64.3% respectively. IL-2 of BALF was not detected in 83.4% of squamous cell lung cancer cases (Gr. I) before treatment. The average IL-2 BALF concentration of the remaining portion of this group was 80.49pg/ml/mg p. IL-2 was detected in Gr. II (x = 151.003 pg/ml/mg p.) after combined cancer resection. An inverse correlation was found between IL-2 BALF concentration and disease stage.

The prognostic significance of neutropenic fever in lung cancer patients receiving chemotherapy with or without radiotherapy was investigated. Male patients and patients with squamous cell lung cancer had a higher incidence of febrile episodes than female patients and patients with other cell types, but the differences were not significant. Patients with a poor performance status had a significantly higher incidence of febrile episodes. An indwelling central venous catheter was an important risk factor for febrile episodes, indicating that bacteremia was one of the major causes of fever. The median survival time of the patients who developed febrile episodes during chemotherapy was significantly shorter than that of patients without fever (6.1 vs 12.0 months), whether or not cases of early death within 3 months were excluded (8.9 vs 13.1 months). The prevention of infectious complications during anticancer treatment by the use of rh G-CSF and the early initiation of antimicrobial chemotherapy, although the results are inconclusive, may be worthwhile.

Forty six patients with T3 lung cancer underwent pulmonary resection in our institutes. The actual survival rate of lung cancer patients with invasion in pericardium at five years is significantly higher than that in parietal pleura and chest wall (63.5% vs 13.2%, 11.1%). The survival rate of patients with large cell lung cancer is significantly lower than that with squamous cell lung cancer and small cell lung cancer (0.0% vs 39.9%, 16.7%). It is suggested that T3 large cell lung cancer patients might be contraindication of pulmonary resection. The five-year survival rate of patients with n0, n1, n2 disease are 35.5%, 66.7%, 6.7% respectively. There are significant differences in survival rate between patients with n0 + n1 and n2 disease.

Myocardial involvement by malignant neoplasm is rare and often not clinically manifested. The diagnosis is usually made only at autopsy. A 71-year-old man with squamous cell lung cancer presented with chest discomfort. His electrocardiogram was diagnostic of acute myocardial infarction. However, because of the lack of classic symptoms and signs of acute myocardial infarction and normal serum levels of cardiac enzymes, an echocardiography was performed before initiation of thrombolytic therapy. The echocardiography showed a huge hyperechoic mass located in the posterolateral aspect of the left ventricle with myocardium invasion. Thrombolytic therapy was withheld. In patients with lung cancer, an electrocardiogram representative of acute myocardial infarction can rarely be induced by myocardial involvement with lung cancer.

A 57-year-old man with myasthenia gravis had undergone extended thymothymomectomy for invasive thymoma and postoperative irradiation 15 years ago. At present, an abnormal shadow on his left lung field on chest X-ray and an elevated SCC-Ag level led us to suspect primary lung cancer (squamous cell lung cancer). He underwent left lower lobectomy and partial resection of the upper lobe. After the operation, this tumor was identified pathologically as a thymoma. Comparing this tumor with the previous invasive thymoma, we concluded that the present lesion was a metastasis of the former thymoma. This case suggests that a metastatic lung tumor should be suspected when an abnormal shadow is detected on chest X-ray following extended thymothymomectomy for invasive thymoma.

We report a case of squamous cell lung cancer with nephrotic syndrome. A 69-year-old man was admitted because of proteinuria and microhematuria. A plain chest X-ray film on admission showed a large mass in the left-lower lung field. The patient was given a diagnosis of minimal-change-nephrotic syndrome and squamous cell lung cancer. We first treated the nephrotic syndrome with glucocorticoid therapy, and then treated the lung cancer with chemo-radiotherapy. This reduced the lung cancer, alleviated the proteinuria, and completely resolved the nephrotic syndrome. Nephrotic syndrome is generally associated with malignant lymphoma and other nonepithelial neoplasms. As the underlying disease, epithelial neoplasms are less common, but lung cancer is one of the most widely reported. Histologically, most cases of cancer-associated nephrotic syndrome exhibit membranous nephropathy; Minimal-change nephrotic syndrome is rare. Deposits of immunocomplex on glomerular basement membrane are considered to play a pathogenic role in membranous nephropathy. However, the pathogenesis of minimal-change nephrotic syndrome is different.

We reviewed our experience with pneumonia in patients with lung cancer over a 14-year period at Kurume University Hospital. We examined the clinical features and significance of pathogenic microbes isolated from sputum in patients with lung cancer complicated by pneumonia. Many investigators have noted that patients with squamous cell lung cancer tend to contract pneumonia more readily than patients with cancers of other histopathological types. Our review, however, disclosed no significant differences among histopathological types. Bacteriological examinations of sputum revealed the frequent involvement of Staphylococcus aureus, Enterococcus faecalis, and various gram-negative organisms (e.g., Pseudomonas, Acinetobacter, Enterobacter, and Klebsiella species) that are known to be causative agents of hospital-acquired infection. Beta-lactam and CLDM were less effective. Carbapenem used alone as the second regimen of treatment for lung cancer patients with pneumonia was found to be as effective as combination therapy with beta-lactam and aminoglycoside. However, more detailed investigations (e.g., randomized prospective studies) will be needed to identify suitable antibiotics against pneumonia in patients with lung cancer. We concluded that it will be necessary to evaluate the clinical features and outcome of pneumonia in lung cancer patients in order to provide more effective treatment.

Lung cancer is the leading cause of cancer death in Taiwan. Potential molecular markers associated with cancer susceptibility and prognosis are the genes involved in tumorigenesis. Therefore, we investigated the association of p53 codon 72 polymorphism with prognosis in 114 lung cancer patients. The estimated median survival times for patients with proline (Pro)/Pro, arginine (Arg)/Arg, and Arg/Pro genotypes were 25, 26 and 36 months, respectively. We also found that patients with the Pro/Pro genotype had a worse prognosis compared with those with Arg/Pro genotypes, especially for patients with squamous cell lung cancer (P = 0.013), male patients (P = 0.028) and those aged 60-69 years (P = 0.052). In patients with early stage lung cancer, patients with Pro/Pro and Arg/Arg genotypes had a tendency for a worse prognosis than those with the Arg/Pro genotype (P = 0.057). Our data suggest that p53 codon 72 polymorphism may be a potential prognostic factor in certain sub groups of lung cancer patients in Taiwan.

Epidemiological studies indicate that low serum total cholesterol level may increase the risk of death due to cancer, mainly lung cancer. The aim of our study was to evaluate serum levels of total cholesterol (TC) and triglycerides (TG) in patients with squamous cell and small cell lung cancer and their dependence on the histological type and the clinical stage of the neoplasm. Lung cancer patients (n=135) and healthy controls (n=39) entered the study. All lung cancer patients had higher rate of hypocholesterolemia and lower TC and TG levels than the control group. TC concentration was lower in lung cancer patients and in both histological types in comparison with the control group, TG level was lower only in patients with squamous cell lung cancer. There were no statistically significant differences of TC and TG levels between the histological types, or between the clinical stages of each histological type.

A 62-year-old nonsmoking female was admitted to our hospital in May, 1998 complaining of marked cough accompanied by repeated hemosputa. Chest X-ray and CT examinations revealed a large tumor, located adjacent to a cystic lesion in the left lower lung field, in association with a clearly recognizable swelling of the ipsilateral hilar as well as the mediastinal lymph nodes. Sputum cytology after bronchofiberscopy led to the diagnosis that the patient suffered from squamous cell lung cancer of Stage IIIA with bulky N2 (T2N2M0). Chemotherapy was selected as the most reasonable treatment for this patient. The new chemotherapeutic agent docetaxel (60 mg/m2) in combination with cisplatin (CDDP: 80 mg/m2) was tried, resulting in a remarkable reduction in tumor size by 60% after the initial course of chemotherapy was completed, which fulfilled the definition of a partial response (PR). Furthermore, after 4 courses of the chemotherapy, the hilar and mediastinal lymphadenopathy had conspicuously abated and only scar tissue was visible at the site where the lung cancer was thought to have originally developed. We herein report a case in which squamous cell lung cancer sprouted in a nonsmoking female, who was successfully treated by the combined chemotherapy of docetaxel and CDDP. The present case may suggest the efficacy of newly developed docetaxel in treating non-small cell lung cancer.
