Materials and Methods: Of the 580 pulmonary adenocarcinomas diagnosed between March 2010 and February 2011, immunohistochemical staining for ALK was performed in 269 cases showing any suspicious histologic features in previous reports. The subtype according to the World Health Organization classification and the characteristic histologic features were re-evaluated in ALK-expressing cases. Results: A total of 46 cases (7.9% of the 580 adenocarcinomas, 17.1% of the 269 studied cases) were positive for ALK. Among the 46 cases showing ALK positivity, 35 cases (76%) showed intra- and/or extra-cytoplasmic mucin. The most well-known characteristic finding associated with ALK, signet ring cells, was found in 18 cases (39.1%). Cribriform pattern with extracytoplasmic mucin was identified in five cases. In six cases, all three features were found. On the other hand, there were three other cases that did not show any of the aforementioned histologic features. In 12 lobectomy specimens, the most common histologic pattern was a solid pattern (five cases, 41.6%). Conclusion: Intra- and/or extra-cytoplasmic mucin, including signet ring cell appearance and a cribriform pattern with extracytoplasmic mucin, are characteristic features of ALK-expressing non-small cell lung cancer.

Most CTCs require an initial enrichment step, since CTCs are a very rare event. The different technologies and also the differences among the screened populations make the clinical significance of detecting CTCs difficult to interpret. Peripheral blood analyses are more convenient for patients than invasive BM sampling and many research groups are currently assessing the clinical utility of CTCs for assessing the prognosis and monitoring the response to systemic therapies in lung cancer patients. Here we will review the different assays that are currently available for CTC detection and analysis of lung cancer.

Most patients present with advanced disease that requires systemic chemotherapy, which merely confers several months of survival benefit. Recent advances in understanding the molecular mechanisms underlying lung cancer have led to molecular targeted therapy in this field. Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are the first successful personalized therapy for non-small cell lung cancer (NSCLC), with about 30 months of median overall survival in patients with sensitive EGFR mutations. In addition, monoclonal antibodies against vascular endothelial growth factor (VEGF) or EGFR are also in current clinical use. Resistance to EGFR-TKIs has emerged as a major limitation of these agents and become challenge clinically. A number of novel targeted agents have been developed and investigated in clinical trials to overcome the limitation of agents currently available. Recently, echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase fusion gene ( EML4-ALK), as a novel molecular target of NSCLC, has been identified, and its inhibitor is under rapid clinical development. We herein review the molecular targeted therapies currently available for NSCLC and discuss the clinical data of novel agents under clinical development.

Materials and Methods: Patients with pathologically-confirmed LD SCLC with the following inclusion criteria were retrospectively analyzed: age ≥18 years; measurable lesion; Eastern Cooperative Oncology Group Performance Status 0 ∼2; chemotherapy naive; and adequate bone marrow and organ function. Patients received an intravenous (IV) infusion of irinotecan (35 mg/m 2 on days 1, 8, and 15) and cisplatin (60 mg/m 2 on day 1), which was repeated every 4 weeks for up to 6 cycles. Concurrent TRT was administered with the beginning of chemotherapy. Irinotecan was increased to 60 mg/m2 after completion of TRT. Patients with a complete response (CR) subsequently received prophylactic cranial irradiation. Results: Nineteen patients were analyzed. There were 8 patients (42.1%) with CR, 9 patients (47.4%) with partial response, and 1 patient each (5.3%) with stable disease and progressive disease (PD). The overall response rate was 89.5%.

Materials and Methods: From 2004 to 2008, 21 patients received curative radiotherapy for locoregionally recurrent NSCLC without systemic metastasis after surgery. At the time of recurrence, the median age was 70 years (range 49∼81 years), and 19 patients were male. Most patients (n=17) were ECOG 0 or 1 performance status. The median disease-free interval was 15 months. Distribution of recurrence sites were mediastinal lymph nodes (n=10), ipsilateral hilar lymph nodes (n=4), ipsilateral lung parenchyma (n=4), bronchial stump (n=2) and ipsilateral supraclavicular lymph nodes (n=1). Radiotherapy was administered (median 66 Gy, range 59.4∼70 Gy) by a three-dimensional conformal technique. Thirteen patients received chemotherapy concurrently during radiotherapy. Pulmonary function test (PFT) was also used to detect lung function change before and after radiation. Results: The median survival and 1and 2-year survival rates were 17 months, 68% and 34%, respectively. Concurrent chemotherapy did not affect postrecurrence overall survival (p=0.183). Seven patients (33% of all patients) had re-progression within the radiation field at a median time of 4 months after completion of radiation. Diffusing lung capacity for carbon monoxide of lung after radiotherapy decreased significantly compared with pre-radiotherapy status (p=0.033). Radiation pneumonitis of any grade was seen in 11 patients. Three patients died of pulmonary complications: one of bacterial pneumonia, one of exacerbation of underlying interstitial pulmonary fibrosis and one of radiation pneumonitis. Conclusion: This retrospective study showed that curative radiotherapy for locoregionally recurrent NSCLC resulted in a median survival of 17 months and a 2-year survival rate of 34%, which is comparable to other studies. Patients suitable for curative radiotherapy for recurrent NSCLC could be treated aggressively, such as using high dose radiation with or without chemotherapy.

Docking proteins (DOKs) are tyrosine-phosphorylated proteins that negatively regulate tyrosine kinase signaling and they are considered to be tumor suppressors. Deletion and the altered expression of the DOK2 gene have been studied in leukemias and lung cancers. However, the somatic mutation status of the DOK2 gene has not been studied in lung cancers. The aim of this study was to see whether alterations of DOK2 protein expression and somatic mutation of the DOK2 gene are present in human non-small cell lung cancer (NSCLC). Materials and Methods: We analyzed DOK2 somatic mutation in 45 NSCLCs (23 adenocarcinomas (AD) and 22 squamous cell carcinomas (SCC) by single-strand conformation polymorphism (SSCP). We examined the DOK2 protein expression in 45 NSCLCs by immunohistochemistry. Results: SSCP analysis revealed no evidence of somatic mutation in the DNA sequences encoding the DOK2 gene in the 45 NSCLCs. Among the informative cases, 27% and 21% of the ADs and SCCs showed allelic loss in the DOK2 locus, respectively. On the immunohistochemistry, DOK2 protein was expressed in the normal bronchial epithelial cells, while it was lost in 10 (22%) of the NSCLCs. Conclusion: Our data indicates that DOK2 is altered in NSCLC at the expressional level, but not at the mutational level. The data also suggests that loss of the expression of DOK2 might play roles in NSCLC development by possibly altering tyrosine kinase signaling.

Many pathways are known to affect tumor growth, and targeting these pathways provides the cornerstone by which cancer is treated. Somatostatin receptors (SSTR) are a family of G protein coupled receptors that signal to alter hormonal secretion, increase apoptosis, and decrease cellular proliferation. These receptors are expressed in many normal and malignant cells, including both small cell and non-small cell lung cancer. Synthetic analogs of SSTRs are commercially available, but their effects in lung cancer are still largely uncertain. Signaling pathway studies have shown that SSTRs signal through phosphotyrosine phosphatases to induce apoptosis as well as to decrease cell proliferation. Radiolabeled SSTR2 analogs are utilized for radiographic imaging of tumors, which, when combined with positron emission tomography-computed tomography (PET-CT) may improve detection of lung cancer. These radiolabeled SSTR2 analogs also hold promise for targeted chemotherapy as well as radiotherapy.
