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: The main goal of this study was to evaluate the diagnostic efficacy of reverse transcription-nested polymerase chain reaction (RT-nested PCR) in bronchial washing fluid with MAGE A1-6 common primers for the detection of lung cancers invisible by bronchoscopy. Methods: To determine the expression of MAGE A1-6 gene in 189 lung cancers diagnosed by conventional fluoroscopy-guided lung biopsy and 89 cancer-free controls, RT-nested PCR was performed in bronchial washing specimens. We analyzed MAGE A1-6 RT-nested PCR data according to tumor histology, stage, size, and compared them with cytological data. Results: 189 patients (111 cases in adenocarcinoma, 47 cases in squamous cell carcinoma, 22 cases in small cell lung carcinoma, and 9 cases in other cancers) and 89 benign patients were investigated. The expression of MAGE was performed by nested RT-PCR using common MAGE primer. Among 189 cancer patients, the expression rate of MAGE was 49.2%, and the positive predictive value was 89.4%. However, the expression rate of MAGE in patients with benign lesions was 12.4%. In peripheral lung cancer, the positive rate of MAGE expression was 57.4% in squamous cell carcinoma, 44.1% in adenocarcinoma and 59.1% in small cell lung cancer. Whereas the expression rate of bronchial washing cytology in peripheral lung cancer was 9.0% (p=0.011). Conclusion: MAGE RT-PCR in bronchial washing fluid gave us promising data for the detection of peripheral lung cancer. It could be a useful method for selecting diagnostic tools for peripheral lesions.

Percutaneous needle aspiration has been widely used in the diagnosis of pulmonary lesions, because it is a fairly simple procedure with good diagnostic accuracy and low complication rate. Among its complications, the spread of malignant cells along the needle tract is rare but serious one. We report a case of chest wall implantation of lung cancer after the percutaneous fine needle aspiration biopsy. A 57-year-old man had undergone a right upper lobectomy for squamous cell carcinoma [T2N0M0] of the lung, 3 months after the operation, a growing mass, located far from the previous thoracotomy incision, developed on the right anterior chest wall where the diagnostic thin needle biopsy had been performed before the lobectomy. A wide excision of the chest wall mass was performed, and permanent histology showed squamous cell carcinoma as noted before.

Background: Prior series investigated the expression of prepro-gastrin releasing peptide (prepro-GRP) in the peripheral blood of lung cancer patients. Our aim was to assess any prepro-GRP role as a prognostic factor for small cell lung cancer (SCLC) and NSCLC and correlations with clinical presentation and treatment outcome. Methods: A prospective study was conducted during the time period from the beginning of January 2012 till the end of January 2014. Prepro-GRP expression was analysed using a nested RT-PCR assay in peripheral blood of 62 untreated lung cancer patients attending the National Cancer Institute (NCI), Cairo University, and 30 age and sex matched healthy volunteers. Results: Among the 62 lung cancer cases, there were 24 (38.7%) SCLC, and 38 (61.3%) NSCLC (10 squamous cell carcinomas, 12 adenocarcinomas, 11 large cell carcinomas, 4 undifferentiated carcinomas, and 1 adenosquamous carcinoma). Twenty six patients (41.9%) were prepro-GRP positive. Prepro-GRP expression was higher (58.3%) among SCLC patients compared to NSCLC (squamous cell carcinoma (15.4%), large cell carcinoma (36.4%), and adenocarcinoma (25%)). Mean OS among prepro-GRP negative cases was longer than that among preprogastrin positive cases (17.6 vs 14.9 months). The mean PFS durations among preprogastrin negative versus positive cases were 7.7 vs 4.6 months (p= 0.041). No difference in response to chemotherapy was identified between the groups (p=0.983). Conclusion: Prepro-GRP is suggested to be a useful prognostic marker for lung cancer patients, especially with the fast- growing, bad prognostic SCLC type. More studies should aim at detailed understanding of the mechanisms of prepro-GRP action and its use in monitoring the response to treatment in a larger cohort.

Primary lung cancer commonly metastasizes to the brain, bones, liver, and adrenal glands. In some cases, bone metastasis serves as the first presenting sign of lung cancer with bone pain and headache, but it is not common. The incidence of skull metastasis in lung squamous cell carcinoma (SCC) is low, and there have been only a few cases of skull metastases serving as the first sign of malignancy with skull mass and epidural bleeding; however, no similar cases have been reported regarding that of hematoma. We report a case of an 84-year-old man who first presented with a simple forehead hematoma and was eventually diagnosed with SCC of the lung.

A 64-year-old male was admitted due to weight loss of 5kg during a month. Chest X-ray showed two large, lobulated masses on both lower lobe. Chest CT showed ill-defined, multilobulated mass on left lower lobe and irregular, relatively homogenous mass with air-bronchogram on right lower lobe. Left lower lobectomy and right lower lobectomy was performed sequentially with three months interval. Microscopic findings showed squamous cell carcinoma of both mass. It was thought that this patient had synchronous double primary lung cancer.

Carcinosarcoma of the lung is an admixture of cardinomatous and sarcomatous lesion and accounts for 0.3% of all pulmonary neoplasm. Clinicopathological features are often related to anatomical location : central endobronchial type and peripheral parenchymal type. Noninvasive diagnostic tests had a low yield in detection carcinosarcoma. Metastasis to regional lymph nodes and to distant organ is common. The prognosis is poor and the median survival is less than one year.Two cases of carcinosarcoma patients are reported here - one case is composed of undifferent cell carcinoma and spindle cell sarcoma in the male of 72 year old and the other case squamous cell carcinoma and spindle cell sarcoma in the male of 65 year old.

Background: Pemetrexed has been prescribed newly as a second line chemotherapy in advanced non-small cell lung carcinoma (NSCLC). The aim of study was to determine the efficacy and toxicity of pemetrexed in advanced NSCLC. Methods: Patients with histologically or cytologically confirmed NSCLC were evaluated from June 2006 to December 2008. The patients had relapsed or progressed after prior chemotherapy treatment. They were treated with intravenous pemetrexed $500mg/m^2$ for 10 min on Day 1 of each 21-day cycle. Results: A total of 89 patients were eligible for analysis. The response rate and disease control rate were 11% and 66%. Non-squamous cell carcinoma histology was significantly associated with a superior response rate (p=0.035) and disease control rate (p=0.009) than squamous cell carcinoma histology. The median survival time was 13 months and the median progression free survival time was 2.3 months. The median survival time of patients with ECOG PS 0~1 was 13.2 months, whereas median survival time was 11.6 months for patients with PS 2 (p=0.002). The median progression free survival time of patients with PS 0~1 were 3.8 months, but 2.1 months for patients with PS 2 (p=0.016). The median progression free survival time of smokers with non-squamous cell carcinoma was 3.4 months, which was significant (p=0.014). Grade 3~4 neutropenia were seen in 7.9% patients. Conclusion: Pemetrexed has efficacy in patients who had prior chemotherapy with advanced NSCLC and less hematologic toxicity.

Objective: Cyclooxygenase-2 (COX-2) has been claimed to play role in carcinogenesis and be related to a bad prognosis in tumours. The aim of this study was to investigate the relationship between COX-2 expression and clinical and pathological parameters in early and advanced stage lung cancer patients. Materials and Methods: A total of 73 patients with lung cancer (27 adenocarcinomas, 33 squamous cell carcinomas, 4 large cell carcinomas and 9 small cell cancer) were analysed retrospectively. COX-2 expression was evaluated by immunohistochemistry in resection materials or lung biopsies. Tumor cells demonstrating more intense staining than smooth muscle and endothelial cells were recorded as COX-2 positive. We investigated the correlation between increased COX-2 expression and histological type of the tumor, the stage of the disease and survival. Results: COX-2 expression was observed in 55% of the adenocarcinomas, 45% of the squamous cell carcinomas and 22% of the small cell carcinomas. No correlation was apparent between COX-2 expression and disease stage, histological type and the survival. Conclusion: The results of this study do not support COX-2 expression as an independent prognostic factor in lung cancer. However, since results of the literature are different, further studies made in larger series are needed.
