Background : Lung cancer is one of the most common malignancy in the world. Types of lung cancer are Non small cell lung cancer and small cell lung cancer. Subtypes of Non small cell lung cancer are adenocarcinoma, squamous cell carcinoma and large cell carcinoma. Knowing the type of lung cancer is important in determining both treatment and prognosis. Recently, due to newly developed anti-cancer drugs, squamous cell carcinoma has relatively poor prognosis than non-squamous cell carcinoma. Case : We report a squamous cell lung cancer case treated with allergen removed Rhus verniciflua Stokes (aRVS) extract. The patients initially diagnosed stage squamous cell lung carcinoma, but she refused recommended operation. She initiated aRVS extract monotherapy in October. 2006. The follow up Computed tomography in March. 2007, she diagnosed stable disease of tumor response on aRVS treatment. However, this case was lost to follow up for 6 months while she was treated with tomotherapy. In October 2007, she came back to our cancer center after diagnosed stage IV metastasized lung to lung, and aRVS monotherapy was restarted. She had survived 2 years after metastasis of squamous cell lung carcinoma. Conclusion : Allergen removed Rhus verniciflua Stokes(aRVS) sucessfully prolonged overall survival of a squamous cell lung cancer patient.

Knowledge of molecular pathogenesis of non-small cell lung cancer has increased remarkably and changed the principles of treatment, especially during the past decade. These advancements have been limited mainly to adenocarcinoma of the lung. Recently, genetic alterations in squamous cell lung cancer (SQCLC) have been detailed and positive results of clinical trials using agents targeting these changes have indicated the potential for improved treatment outcomes for SQCLC.

Primary lung cancer is unusual in children; the squamous cell variant is extremely rare. Lung cancer is classified by histologic types into small-cell lung cancer, non-small cell lung caner, carcinoid, mucoepidermoid carcinoma, and adenoid cystic carcinoma. Furthermore, non-small cell lung cancer is subclassified into adenocarcinoma, large-cell carcinoma, and squamous cell carcinoma. The incidence of lung cancer is influenced by smoking, especially in squamous cell carcinoma, and large cell carcinoma. The present treatments for these tumors are chemotherapy, radiation therapy, and surgical resection depending on their histologic types or stages, but yield very poor survival rates. In this article, we report a case of basaloid squamous cell lung carcinoma in an 11-year-old boy who had symptoms of both leg weakness and back pain radiating to both legs. We confirmed the primary lung carcinoma cells by percutaneous transthoracic needle biopsy. The metastatic carcinoma cells were identified at the bone marrow and lumbar spine. We treated with a combination chemotherapy and radiation therapy. However, he expired 4 months after the onset of disease.

Background: Lung cancer is the leading cause of cancer mortality in the world. Many factors can protect against or facilitate its development. A TNF family member TRAIL, has a complex physiological role beyond that of merely activating the apoptotic pathway in cancer cells. Vitamin D is converted to its active form locally in the lung, and is also thought to play an important role in lung health. Our goal was to investigate the possible clinical significance of serum sTRAIL and 1,25-dihydroxyvitamin D(3) levels in patients with non-small cell lung cancer (NSCLC). Materials and Methods: Totals of 18 consecutive adenocarcinoma and 22 squamous cell carcinoma patients with stage-IV non-small cell lung cancer referred to our institute were included in this study. There were 12 men and 6 women, with ages ranging from 38 to 97 (mean 60.5) years with adenocarcinoma, and 20 men and 2 women, with ages ranging from 46 to 80 (mean 65) years with squamous cell carcinoma. Serum levels of sTRAIL and 1,25-dihydroxyvitamin D(3) were measured in all samples at the time of diagnosis. Results: sTRAIL levels in NSCLC patients were higher than in the control group. Although there was no correlation between patient survival and sTRAIL levels, the highest sTRAIL levels were correlated with age and cigarette smoking in the adenocarcinoma patients. sTRAIL level in healthy individuals were correlated with serum 1,25-dihydroxyvitamin D(3). Conclusions: Serum sTRAIL concentrations were increased in NSCLC patients, and correlated with age and smoking history, but not with overall survival.

The lung adenocarcinoma is considered more aggressive than other types of non-small cell lung cancer. As metabolites of tryptophan degradation along the kynurenine pathway, including kynurenic acid, have been shown to induce immunosuppression and facilitate escape of tumor cells from immune surveillance, a hypothesis was set up that differences in biological behavior between types of lung cancer may be associated with altered activity of the kynurenine metabolic pathway. The aim of the study was to determine kynurenic acid levels in the serum of patients with bronchial adenocarcinoma for comparison with other types of non-small cell lung cancer. A total of 227 patients with non-small cell lung cancer were enrolled in the study, including 71 with adenocarcinoma and 96 with squamous cell carcinoma. Serum kynurenic acid concentration was determined with use of high performance liquid chromatography and fluorometry. The level of kynurenic acid in the serum of patients with adenocarcinoma was significantly higher than in those with squamous cell lung cancer ($107.1{\pm}62.8$ pmol/ml; 95%CI: 92.4 to 132.3 pmol/ml versus $82.1{\pm}47.6$ pmol/ml; 95%CI: 78.5 to 91.2 pmol/ml, respectively; p = 0.027). Differences between other histological types of lung cancer were insignificant. We conclude that increased activity of kynurenine metabolic pathway manifested by elevated serum kynurenic acid level may be one of the factors associated with clinically distinct biological behavior of adenocarcinoma, in particular high invasiveness and rapid progression.

Background: About 30% to 40% of the patients with pathologic stage I non-small cell lung cancer (NSCLC) die within 5 years after complete resection. The identification of poor prognostic factors and the application of additional treatment are very important to improve the survival rate in resected stage I NSCLC. Materials and methods: Sixty-eight(68) patients who had been diagnosed postoperatively between Janury 1989 and December 1995 as having stage I non-small cell lung cancer according to the TNM classification were studied. The postoperative 5-year survival rate was calculated with the Kaplan-Meier method, and clinico- histopathologic factors including age, sex, operative method, type of tumor cell, T factor, grade of the differentiation in a squamous cell carcinoma, invasion of blood vessel and expression of the nm23-H1 protein were investigated and analyzed. Results: The median survival of the entire group of patients was 58$\pm$3 months, with a 5-year survival of 58.9%. In univariate analysis, invasion of blood vessel and poor differentiation of the tumor cell in a squamous cell carcinoma significantly worsened the survival. In multivariate analysis, invasion of blood vessel and grade of the differentiation of the tumor cells in a squamous cell carcinoma remained independent prognostic factors. High expression of the nm23-H1 protein was related to a high postoperative 5-year survival in comparision with low expression of the nm23-H1 pretein (73.0% vs 50.7%), but there was no statistical significance. Conclusions: These results highlight the negative prognostic value of poor differentiation of tumor cells in a squamous cell carcinoma and invasion of blood vessel in stage I non-small cell lung cancer. Also, further studies are necessary to be determined prognostic value of the T factor and expression of the nm23 protein in non-small cell lung cancer.

A proper pathologic diagnosis of small cell lung cancer(SCLC) is essential for the application of aggressive treatment modalities. However, various authors have suggested several subtypes of SCLC based on morphological features. Among them, the incidence of small cell lung cancer(SCLC) combined with squamous cell and/or adenocarcinoma, represents less than 1% to 3% of all SCLC tumors. Because of the rarity of SCLC combined with squamous cell and/or adenocarcinoma, very little is known about its clinical characteristics and response to therapy. We report a case of SCLC combined with squamous cell and adenocarcinoma in a 68 year old male who experienced pneumonectomy of the left lung.

Background: Lung cancer is one of the most common types of cancer causing high morbidity and mortality worldwide. An increasing incidence of lung cancer has been observed in India. Objectives:To evaluate the clinicpathological profile and haematological abnormalities associated with lung cancer in Bangalore, India. Materials and Methods: This prospective study was carried out over a period of 2 years. A total of 96 newly diagnosed and histopathologically confirmed cases of lung cancer were included in the study. Results: Our lung cancer cases had a male to female ratio of 3:1. Distribution of age varied from 40 to 90 years, with a major contribution in the age group between 61 and 80 years (55.2%). Smoking was the commonest risk factor found in 69.7% of patients. The most frequent symptom was cough (86.4%) followed by loss of weight and appetite (65.6%) and dyspnea (64.5%). The most common radiological presentation was a mass lesion (55%). The most common histopathological type was squamous cell carcinoma (47.9%), followed by adenocarcinoma (28.1%) and small cell carcinoma (12.5%). Distant metastasis at presentation was seen in 53.1% patients. Among the haematological abnormalities, anaemia was seen in 61.4% of patients, leucocytosis in 36.4%, thrombocytosis in 14.5% and eosinophilia in 19.7% of patients. Haematological abnormalities were more commonly seen in non small cell lung cancer. Conclusions: Squamous cell carcinoma was found to be the most common histopathological type and smoking still remains the major risk factor for lung cancer. Haematological abnormalities are frequently observed in lung cancer patients, anaemia being the commonest of all.

Objective: To observe the efficacy and toxicity of nanoparticle albumin bound paclitaxel (nab-paclitaxel) plus platinum agent (cisplatin or carboplatin) as first line treatment for stage III/IV squamous non-small-cell lung cancer (NSCLC). Methods: Forty chemotherapy naive patients with stage III/IV squamous NSCLC received nab-paclitaxel $125mg/m^2$ on day 1 and day 8, cisplatin $75mg/m^2$ on day 1, carboplatin area under the concentration-time curve of 5 (AUC=5) on day 1. One cycle of treatment was 3 weeks, and at least two were completed in each case. Results: Of the 40 patients who participated in the study, 25 achieved partial responses (PR), 12 reached a stage of stable disease (SD), and 3 suffered progressive disease (PD). The overall response rate (ORR) was 62.5% and the disease control rate (DCR) was 92.5%. Of the 20 patients without surgery or radiotherapy, 10 achieved PR, 7 reached a stage of SD, and 3 PD. The ORR was 50.0% and the DCR was 85.0%. The median progression-free survival time (PFS) of patients without surgery or radiotherapy was 5.0 months. Of the 20 patients receiving surgery or radiotherapy, 15 had PR and 5 p had SD, with an ORR of 75.0% and a DCR of 85.0%. Specifically, the DDP arm demonstrated a significantly higher ORR than the CBP arm (100%vs 54.5%, P<0.05). Common treatment related adverse events were myelosuppression, gastrointestinal response, baldness and neurotoxicity, most of which were grade 1 to 2. Conclusion: Nab-paclitaxel plus platinum agent (cisplatin or carboplatin) is effective as a first-line chemotheraphy for stage III/IV squamous NSCLC, and its adverse effects are tolerable.

Background: Lung cancer and chronic obstructive lung disease often coexist in the same person who are elderly and cigarette smoking. There are several reports that the presence of chronic obstructive pulmonary disease constitutes an independent risk factor for the development of lung cancer. Moreover, the association between mucus hypersecrtion and lung cacer has been reported. Method: In 72 cases with primary lung cancer which were confirmed histopathologically at Chonbuk University Hospital from August 1986 to July 1991, We evaluated the relationship between spirometry and lung cancer characteristics. Results: Six cases(8.3%) showed normal lung function, 16(22.2%) cases showed pure restrictive lung disease, 46(63.9%) cases showed moderated obstructive lung disease and 4(5.6%) cases showed severe obstructive lung disease. $FEV_1$(%) was lower in central type than in peripheral type, lower in advanced non-small cell cancer and lower in subjects with phlegm. $FEV_1$/FVC(%) was higher in small cell cancer than in squamous cell cancer and higher in patients without previous pulmonary disease than with previous pulmonary disease. But there was no statistically significant difference in lung function according to histologic types and smoking history. Lung cancers with $FEV_1$/FVC less than 75% consisted of 35 cases of squamous cell cancer, 7 of small cell cancer(14%), 5 of adenocarcinoma(10%), 2 of large-cell carcinoma and 1 of unclassified carcinoma. Squamous cell carcinoma occured more in patients with $FEV_1$/FVC<75% than with $FEV_1$/FVC$\geq$75%(p<0.05). Conclusion: It was suggest that low $FEV_1$/FVC, as reflection of obstructive lung disease, may be at greater risk for squamous cell carcinoma in cigarette smoker.
