Background: Docetaxel is one of the standard treatments for advanced non-small cell lung cancer. Docetaxel is usually administered in a 3-week schedule, but there is significant toxicity. In this phase II clinical study, we investigated the efficacy and safety of a 4-weekly schedule of docetaxel monotherapy, as first-line chemotherapy for advanced squamous cell carcinoma in elderly lung cancer patients. Methods: Patients with stage IIIB/ IV lung squamous-cell carcinoma age 70 or older, that had not undergone cytotoxic chemotherapy were enrolled. Patients received docetaxel $25mg/m^2$ on days 1, 8, and 15, every 4 weeks. Primary endpoint was the objective response rate (ORR). Secondary endpoints were progression-free survival (PFS), overall survival (OS), and toxicity profiles. Results: A total of 19 patients were enrolled. Among 19 patients, 17 were for evaluated efficacy and safety. In the intent-to-treat population, ORR and disease control rate (DCR) were 11.8% and 47.1%, respectively. In the response evaluable population, ORR was 16.7% and DCR was 66.7%. Median PFS and OS were 3.1 months and 3.3 months, respectively. There were three adverse grade 3/4 events. Grade 1 neutropenia was reported in one patient. Conclusion: Our data failed to demonstrate efficacy of a 4-weekly docetaxel regimen, in elderly patients with a poor performance status. However, incidence of side effects, including neutropenia, was lower than with a 3-week docetaxel regimen, as previously reported.

연구목적: Cytokeratin 19는 기관지의 상피세포와 같은 단순 또는 가중층상피세포에 국한된 40KD의 산성 분자로 면역조직학적 검사를 통해 cytokeratin 19가 폐암 조직에서 많이 발현되는 것으로 알려져 있다. Cytokeratin 19에 특징적인 단일 클론 항체 BM 19-21과 KS 19-1을 이용한 면역방사계수법, CYFRA 21-1을 이용하여 cytokeratin 19분절이 폐암 특히 편평상피세포암의 진단에 유용한 표지자가 될 수 있다는 보고가 있어 폐암 표지자로서 CYFRA 21-1의 유용성을 조사해 보기 위하여 본 연구를 하였다. 방법: 저자 등은 영남대학교 의과대학 부속병원 내과에 1993년 4월부터 1994년 8월까지 입원한 원발성 폐암 환자 39명(편평상피 세포암 19명, 선암 11명, 소세포암 9명)을 폐암군으로, 비악성 호흡기질환자 15명(폐결핵 8명, 만성 폐색성 폐질환 3명, 폐렴 2명, 만성 폐색성 폐질환과 폐결핵이 동반된 환자 2명)을 대조군으로 하여 새로운 폐암 표지자의 가능성이 있는 CYFRA 21-1의 유용성을 조사하였다. CYFRA 21-1의 측정은 면역방사계수측정 kit인 ELSA-CYFRA 21-1을 사용하였다. 결과: 폐암의 조직학적 분류에 따른 CYFRA 21-1의 혈중 측정치는 편평상피세포암이 $20.2{\pm}4.7ng/ml$, 선암이 $7.2{\pm}1.6ng/ml$, 비소세포암이 $15.5{\pm}4.7ng/ml$로 모두 대조군의 $1.7{\pm}0.5ng/ml$보다 유의하게 증가되어 있었다(p<0.01). 또한 비소세포암중 편평상피세포암에서 선암보다 유의하게 증가되어 있었다(p<0.05). 그러나 소세포암에서는 $2.9{\pm}0.9ng/ml$로 대조군과 유의한 차이가 없었다. CYFRA 21-1의 정상 범위를 3.3ng/ml 이내로 하였을때 소세포암에서는 민감도 11.1%, 특이도 65.2% 였으나, 비소세포암에서는 민감도 70.0%, 특이도 62.5%였고 이 중 편평상피 세포암인 경우 민감도 73.7%, 특이도 75%였으며 선암인 경우 63.6%, 78.9%로 산출되었다. 결론: CYFRA 21-1은 비소세포암의 종양 표지자로 유용성이 있을 것으로 생각되며, 특히 편평상피 세포암의 진단에 도움이 될 것으로 생각되었다.

Combined type of primary lung cancer is a very rare form in clinical experience, which is 3 histologically different variants of bronchogenic carcinoma. These type had a well differentiated squamous carcinoma forming keratin pearls, well differentiated adenocarcinoma and pleomorphic undifferentiated cell carcinoma, usually small cell carcinoma. The patient, a male, 49-Y-0, was complaint coughing, mild dyspnea, blood tinged sputum and chest pain. Under diagnosis of lung cancer preoperatively, the right total pneumonectomy was performed with very difficulty such as arrhythmia, ventilation impairment during post operation course. The histology of specimen was disclose as 3 different histological type, combined lung cancer as squamoadenoundifferentiated carcinoma. The mediastinal nodes were freed from metastasis but the parietal pleural metastatic loci was found. The radio & chemotherapy were performed post-operatively. The patient had been experienced empyema at post-pneumonectomy space and then open drainage procedure and thoracoplasty had been added for treatment course. The patient is alive recently.

From June 1979 to July 1988 for 9 years, total 440 cases of lung cancer[including biopsy and surgical specimen] of the Pusan Paik hospital were examined for the clinical and pathology study. The findings of the study are as follows; [1] The incidence of lung cancer started to increase from 1982, and it again remarkably increased since 1987. Such increase was solely brought by the increase of male lung cancer. Male and female ratio is 5.6: 1. [2] Histopathologically, the most prevalent type is squamous cell carcinoma[60.ado], and next are adenocarcinoma[15.6%] and small cell carcinoma[15.0%]. But in female alone, the most prevalent type is adenocarcinoma[40.3%], and next are squamous cell carcinoma[37.3%] and small cell carcinoma[11.9%]. [3] The absolute number of adenocarcinoma are approximately equally distributed among both sexes until 60 years of age. Above 61 years of age, mostly male was shown while female was not. Most probably, many female patient.- of that old age simply did not visit general hospitals for surgery in Korea. [4] Surgical treatment was performed in 8% of total cases of lung cancer. And most cases showed stage I progression of the cancer. Average size of the cancer was 5 cm in diameter in the operated 35 cases suggesting that the cancer could be detected more than 10 years ago before the time of surgery. [5] Lung cancer affected more in the right lung [right: left=1.6: 1], and each upper lobe of both lungs are affected about 1/4 of cases indicating that about 1/2 of all lung cancer develop from the upper lobes. [6] There are more nonsmokers[67.6%] among the lung cancer patients[male 64.6%, female 82.1%]. Probably, this will mean that there are other potent carcinogenic agents in our environment like automobile exhaust beside tobacco smoke. For the past history of lung disease other than cancer, tuberculosis is the most prevalent disease[16.1%, male 17.4%, female 9.0%]. Most of them is probably not related etiologically though this possibility is not completely denied.

The clinical and radiographic findings of lung cancer have been well established many journals. Even if the radiographic findings of lung cancer show a typical pattern, the specific cell type of lung cancer sometimes needs to be determined prior to a pathological diagnosis. For example, the usual finding of a squamous cell carcinoma is similar to other cancer types such as an adenocarcinoma or a small cell carcinoma but with a lower incidence. Therefore, it should not be used to make a diagnosis of the cell type prior to a pathological diagnosis. Many unusual findings of lung cancer, so called atypical pattern have been reported, but atypical findings are widely accepted. The more important thing is not to diagnose a specific cell type of cancer but to differentiate it from other benign conditions such as tuberculosis, fungal infections or organizing pneumonia. This paper presents typical information of the cell type of lung cancer along with the atypical radiographic findings.

Metastasis of lung cancer to the skin is uncommon, presenting in 0.22% to 12% of lung cancer patients, and it is extremely rare for skin metastasis to be the first clinical manifestation of lung cancer. In the few cases where skin metastasis has been reported as the first sign of lung cancer, the patients were typically heavy smokers or had preexisting respiratory diseases and symptoms. This prompted clinicians to consider skin metastasis of a pulmonary malignancy. Large cell neuroendocrine carcinoma (LCNEC) is a rare type of lung cancer that accounts for approximately 3% of lung cancers. LCNEC mainly metastasizes to visceral organs, such as the liver, bone, and brain, and it only shows metastasis to the skin in very rare cases. Herein, we report an unusual case of a metastatic skin lesion as the first sign of primary pulmonary LCNEC, in a 63-year-old woman with no pulmonary symptoms or personal history of smoking or pulmonary disease.

Background: To compare the current histologic distribution of lung cancer in Lebanon to the worldwide trends, according to the 2004 WHO Classification. Materials and Methods: 1,760 patients with a pulmonary pathology examination at Hotel-Dieu de France University Hospital between July 2009 and July 2014 were included. Results: Some 676 out of the total investigated patients (38.4%) had a lung tumor. In 665 (98.4%) the tumors were malignant, with a mean age at diagnosis of 63.8 years and a male/female (M/F) sex ratio of 1.7:1. Among the malignant tumors, 86.2% were epithelial tumors with a mean age at diagnosis of 64.8 years and an M/F sex ratio of 1.9. Other malignant tumors consisted of metastatic tumors (10.2%), lymphoproliferative tumors (2.1%) and mesenchymal tumors (1.5%). Most common carcinoma subtypes were adenocarcinoma (48.0%), squamous cell carcinoma (23.0%) and small cell carcinoma (13.3%). Carcinoid tumors were the only carcinoma subtype with an M/F sex ratio below 1 (0.7). Salivary gland tumors were the carcinoma with lowest mean age at diagnosis (45.5 years). Conclusions: The histologic distribution of lung tumors in Lebanon is similar to that in developed countries. We believe this resemblance is due to common smoking habits, known to be responsible for the increase of lung adenocarcinoma at the expense of other subtypes.

Primary pulmonary lymphoepithelioma-like carcinoma (LELC) is rare, with a more favorable prognosis compared with that of other types of non-small cell lung cancers. Herein, we describe an interesting case of primary pulmonary LELC confirmed postoperatively, which had been initially diagnosed as poorly differentiated adenocarcinoma. We suggest that despite the rarity of pulmonary LELC, it should be included as one of the differential diagnoses for lung malignancies. Physicians should consider taking a larger biopsy, especially when histologic examination shows undifferentiated nature.
