폐의 기저세포양 편평세포암은 2015년 WHO 분류체계에서 편평세포암의 한 아형으로 분류되었고 폐암에서는 드물기에 잘 알려지지 않은 유형이다. 저자들은 두 기저세포양 편평세포암 증례를 보고하고 이들의 전산화단층촬영 영상소견을 명시하고자 한다. 85세 그리고 68세의 기저세포양 편평세포암을 가진 환자가 내원하여 수술적 절제를 시행 받았다. 전산화단층 촬영에서 두 병변은 각각 3.1과 2.8 cm 크기로 경계가 좋으며, 둥글면서 소엽상 경계였고 내부는 괴사를 시사하는 저음영이 풍부하였다. 후자는 수술 후 20개월 동안 추적 관찰하였고 전산화단층촬영에서 재발은 없었다. 비록 드문 아형의 폐암이지만 이러한 전산화단층촬영 소견을 공유한다면 기저세포양 편평세포암을 고려해 볼 수 있겠다.

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.

Squamous cell carcinoma and adenocarcinoma are the major histological types of non-small cell lung cancer. Because they differ on the basis of histopathological and clinical characteristics and their relationship with smoking, their etiologies may be different; for example, different tumor suppressor genes may be related to the genesis of each type. We used microarray data to construct three regulatory networks to identify potential genes related to lung adenocarcinoma and squamous cell carcinoma and investigated the similarity and specificity of them. In the network, some of the observed transcription factors and target genes had been previously proven to be related to lung adenocarcinoma and squamous cell carcinoma. We also found some new transcription factors and target genes related to SCC. The results demonstrated that regulatory network analysis is useful in connection analysis between lung adenocarcinoma and squamous cell carcinoma.

Background: Globally, there have been important changes in trends amongst gender, histology and smoking patterns of lung cancer cases. Materials and Methods: This retrospective study was conducted on 466 patients with lung cancer who were registered in Regional Cancer Center, Regional Institute of Medical Sciences, Manipur from January 2008 to December 2012. Results: Most were more than 60 years of age (67.8%) with a male: female ratio of 1.09:1. Some 78.8% of patients were chronic smokers with male smoker to female smoker ratio of 1.43:1. Consumption of alcohol was found in 29.4%, both smoking and alcohol in 27.5%, betel nut chewing in 37.9% and tobacco chewing in 25.3%. A history of tuberculosis was present in 16.3% of patients. The most frequent symptom was coughing (36.6%) and most common radiological presentation was a mass lesion (70%). Most of the patients had primary lung cancer in the right lung (60.3%). The most common histological subtype was squamous cell carcinoma (49.1%), also in the 40-60 year age group (45.9%), more than 60 year age group (51.6%), males (58.1%) and females (41.8%). As many as 91.9% of squamous cell carcinoma patients had a history of smoking. About 32.5% of patients had distant metastasis at presentation with brain (23.8%) and positive malignant cells in pleural effusions (23.1%) as common sites. The majority of patients were in stage III (34.4%), stage IV (32.5%) and stage II (30.2%). Conclusions: Our analysis suggests that the gender gap has been narrowed such that about half of the patients diagnosed with lung cancer are women in this part of India. This alarming rise in female incidence is mainly attributed to an increased smoking pattern. Squamous cell carcinoma still remains the commonest histological subtype. Most of the patients were elderly aged and presented at locally or distantly advanced stages.

Objective To derive further studies evaluating the effectiveness of Cultured Wild Ginseng Pharmacopuncture (CWGP) Therapy on squamous cell carcinoma as a first line. Methods Three cycles (4 weeks/cycle) of CWGP were administered as a dosage of 10 ml per day. Patient was diagnosed with stage IIIB squamous cell carcinoma and refused all therapy of conventional medicine because of old age and cardiac invasion of tumor. Intensive treatment of CWGP for 3 cycles was done on the patient. Computed Topography (CT) was performed to evaluate the therapeutic efficacy. Results After the intravenous infusion of 2 cycles of CWGP, chest CT revealed the mass size and pleural invasion sustained stable disease. After the point injection of 1 cycle of CWGP, chest CT revealed progressive disease. The disease free survival rate was 1 month. Conclusion This case may provide us the possibility that CWGP offers potential benefits for patients with squamous cell lung carcinoma. But this is a single case study and further case-series research should be compensated.

SCY1-like 1-binding protein 1 (SCYL1BP1) is a newly identified transcriptional activator domain containing protein with many unknown biological functions. Recently emerging evidence has revealed that it is a novel regulator of the p53 pathway, which is very important for the development of human cancer. However, the effects of SCYL1BP1 on human lung squamous carcinoma cell biological behavior remain poorly understood. In this study, we present evidence that SCYL1BP1 can promote the degradation of MDM2 protein and further inhibit the G1/S transition of lung squamous carcinoma cell lines. Functional assays found that reintroduction of SCYL1BP1 into lung squamous carcinoma cell lines significantly inhibited cell proliferation, migration, invasion and tumor formation in nude mice, suggesting strong tumor suppressive function of SCYL1BP1 in lung squamous carcinoma. Taken together, our data suggest that the interaction of SCYL1BP1/MDM2 could accelerate MDM2 degradation, and may function as an important tumor suppressor in lung squamous carcinomas.

Spontaneous pneumothorax is a rare manifestation of primary lung cancer and it is even more rare as an initial manifestation. Recently we have experienced three cases of lung cancer presenting initially as spontaneous pneumothorax. These three cases involved 2 men and one woman with an average age of 70 years [66 - 74years]. Lung cancer was discovered by explothoracotomy in two cases and by endoscopic biopsy in one case. In pathologic cell types, the one was alveolar cell carcinoma and the others were squamous cell carcinoma. We report these three cases of primary lung cancer presenting initially as spontaneous pneumothorax with review of the literatures.
