[PMID: 37240229 DOI: 10.3390/ijms24108883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 05/13/2023] [Accepted: 05/15/2023] [Indexed: 05/28/2023] Open
Abstract
The clinical management of small cell lung cancer (SCLC) treatment remains a major challenge for thoracic oncologists, with very few therapeutic advances significantly impacting patients' survival. The recent introduction of immunotherapy in the clinical setting produced a marginal benefit for a limited subset of metastatic patients, while the therapeutic scenario for relapsing extended-disease small cell lung cancers (ED-SCLCs) remains almost deserted. Recent efforts clarified the molecular features of this disease, leading to the identification of key signalling pathways which may serve as potential targets for clinical use. Despite the large number of molecules tested and the numerous therapeutic failures, some targeted therapies have recently shown interesting preliminary results. In this review, we describe the main molecular pathways involved in SCLC development/progression and provide an updated summary of the targeted therapies currently under investigation in SCLC patients.

Cancer-associated fibroblasts are associated with poor prognosis in solid type of lung adenocarcinoma in a machine learning analysis. Sci Rep 2021; 11:16779. [PMID: 34408230 PMCID: PMC8373913 DOI: 10.1038/s41598-021-96344-1] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Accepted: 07/31/2021] [Indexed: 12/21/2022] Open
Abstract
Cancer-associated fibroblasts (CAFs) participate in critical processes in the tumor microenvironment, such as extracellular matrix remodeling, reciprocal signaling interactions with cancer cells and crosstalk with infiltrating inflammatory cells. However, the relationships between CAFs and survival are not well known in lung cancer. The aim of this study was to reveal the correlations of CAFs with survival rates, genetic alterations and immune activities. This study reviewed the histological features of 517 patients with lung adenocarcinoma from The Cancer Genome Atlas (TCGA) database. We performed gene set enrichment analysis (GSEA), network-based analysis and survival analysis based on CAFs in four histological types of lung adenocarcinoma: acinar, papillary, micropapillary and solid. We found four hallmark gene sets, the epithelial-mesenchymal transition, angiogenesis, hypoxia, and inflammatory response gene sets, that were associated with the presence of CAFs. CAFs were associated with tumor proliferation, elevated memory CD4+T cells and high CD274 (encoding PD-L1) expression. In the pathway analyses, CAFs were related to blood vessel remodeling, matrix organization, negative regulation of apoptosis and transforming growth factor-β signaling. In the survival analysis of each histological type, CAFs were associated with poor prognosis in the solid type. These results may contribute to the development of therapeutic strategies against lung adenocarcinoma cases in which CAFs are present.

Increased VEGF-A in solid type of lung adenocarcinoma reduces the patients' survival. Sci Rep 2021; 11:1321.

Abstract
The histological classification of lung adenocarcinoma includes 5 types: lepidic, acinar, papillary, micropapillary and solid. The complex gene interactions and anticancer immune response of these types are not well known. The aim of this study was to reveal the survival rates, genetic alterations and immune activities of the five histological types and provide treatment strategies. This study reviewed the histological findings of 517 patients with lung adenocarcinoma from The Cancer Genome Atlas (TCGA) database and classified them into five types. We performed gene set enrichment analysis (GSEA) and survival analysis according to the different types. We found six oncogenic gene sets that were higher in lung adenocarcinoma than in normal tissues. In the survival analysis of each type, the acinar type had a favorable prognosis, and the solid subtype had an unfavorable prognosis; however, the survival differences between the other types were not significant. Our study focused on the solid type, which had the poorest prognosis. The solid type was related to adaptive immune resistance associated with elevated CD8 T cells and high CD274 (encoding PD-L1) expression. In the pathway analyses, the solid type was significantly related to high vascular endothelial growth factor (VEGF)-A expression, reflecting tumor angiogenesis. Non-necrosis/low immune response affected by high VEGF-A was associated with worse prognosis. The solid type associated with high VEGF-A expression may contribute to the development of therapeutic strategies for lung adenocarcinoma.

Abstract
DNA replicase polymerase ε (POLE) is critical in proofreading and correcting errors of DNA replication. Low POLE expression plays a pivotal role in accumulation of mutations and onset of cancer, contributing to development and growth of tumor cells. The aim of this study is to reveal the survival, alternative genes and antitumoral immune activities in non-small cell lung cancer (NSCLC) patients with low POLE expression and provide treatment strategies that can increase their survival rates. This study investigated the clinicopathologic parameters, various tumor-infiltrating lymphocytes (TILs), endogenous retrovirus, molecular interactions and in vitro drug screen according to POLE mutation/expression in 168 and 1,019 NSCLC patients from the Konkuk University Medical Center (KUMC) and the Cancer Genome Atlas, respectively. We identified mutations of 75 genes in the sequencing panels, with POLE frame shift p.V1446fs being the most frequent (56.8%) in KUMC based on 170 targeted sequencing panels. Mutant and high expression of POLE correlated with favorable prognosis with increased TILs and tumor mutation burden, compared with wild type and low expression of POLE. We found specific molecular interactions associated with cell cycle and antigen presentation. An in vitro drug screen identified dasatinib that inhibited growth of the NSCLC cell line with low POLE expression. POLE could contribute to the future development of anticancer drugs for patients with NSCLC.

Abstract
Background Small cell lung cancer (SCLC) is a highly aggressive lung cancer subtype with poor survival and limited treatment options. Sequencing results have revealed gene mutations associated with SCLC, however, the correlation between the genomic alterations and clinical prognosis of SCLC is yet unclear. Methods Targeted next-generation sequencing of 62 cancer related genes was performed on 53 SCLC samples. The correlations between clinical outcomes and genomic alterations were analyzed. Results 38/62 (61.3%) candidate genes harbored some alterations, while all the SCLC samples carried at least 3 gene mutations. The most common nonsynonymous mutations included ERBB2 (95.9%), CREBBP (95.9%), and TP53 (77.6%). The median nonsynonymous tumor mutation burden (TMB) was 21.7 mutations/Mb (rang, 9.3–55.9). High TMB (> 21 mutations/Mb) was good prognostic factor in overall survival (OS) (21.7 vs. 10.4 months, P = 0.012). Multivariate analysis showed that high TMB was an independent prognostic factor. The overall survival (OS) of patients carrying KIAA1211 mutation was significantly longer than those with wild-type KIAA1211 (P < 0.001). Conclusions The current study highlights the potential role of genomic alterations for the prognosis of SCLC. Higher TMB was associated with a better prognosis, and KIAA1211 might be a good prognostic factor in SCLC.

Abstract
Aim and background Small cell carcinoma of the prostate (SCCP) is a relatively rare entity, an aggressive tumor with a tendency to metastasize early. There is no standard chemotherapy regimen for SCCP. We report the case of a 67-year-old man with an initial diagnosis of prostate adenocarcinoma with bone metastases who subsequently developed a small cell carcinoma of the prostate with liver metastases. Methods and study design A review of this case and of the current literature was done with a view to highlighting the ideal approach to such an unusual tumor. Results and conclusion The patient was treated with carboplatin and etoposide and after 3 cycles achieved a good response. Unfortunately he developed massive pulmonary embolism which impeded the continuation of treatment and caused his death. By reviewing the literature we found there is no standard of care and new targeted therapies have failed to prove any benefit so far. It is mandatory to persevere in planning trials and exploring new drugs to improve the outcome of patients with SC-C P. It might also be worth creating a register for SCCP where data can be collected to coordinate the management of these patients and to establish better connections among cancer centers.

Trastuzumab emtansine suppresses the growth of HER2-positive small-cell lung cancer in preclinical models. Biochem Biophys Res Commun 2017; 488:596-602.

Abstract
Overcoming chemoresistance is essential for achieving better prognoses in SCLC. Previously, we reported that HER2 is upregulated when HER2-positive SCLC cells acquire chemoresistance. HER2-upregulated cisplatin- or etoposide-resistant SCLC cells were sensitive to trastuzumab-mediated ADCC. However, irinotecan-resistant SCLC cells, such as SBC-3/SN-38, were refractory to trastuzumab despite high HER2 expression. To address this issue, we examined the antitumor efficacy of trastuzumab emtansine (T-DM1) on trastuzumab-resistant HER2-positive SCLC. Treatment with T-DM1 significantly suppressed the growth of SBC-3/SN-38 xenografts in mice compared with trastuzumab (P < 0.05). Histological analysis of xenografts was performed to evaluate the therapeutic effect on apoptosis, proliferation and tumor vasculature. T-DM1 monotherapy induced apoptosis in SBC-3/SN-38 xenografts to a greater extent than trastuzumab monotherapy with the apoptotic index of 3.71 ± 1.56% vs. 0.60 ± 0.32% (P < 0.05), and also inhibited the proliferation of tumor cells compared with trastuzumab with the proliferative index of 74.30 ± 5.54% vs. 80.12 ± 4.81% (P < 0.05). On the other hand, no significant difference in micro vessel density was observed between the treatment groups. In vivo imaging using fluorescence-labeled T-DM1 showed that intravenously administered T-DM1 was rapidly delivered to xenografts and continued to accumulate for several days in a HER2-selective fashion. From these findings, delivery of the cytotoxic agent DM1 into cells via HER2-mediated internalization is expected to exert antitumor effect in such ADCC-lacking SCLC cells. Collectively, T-DM1 will be a promising option for overcoming trastuzumab-resistance in HER2-upregulated SCLC.

Abstract
Chemotherapy represents the cornerstone of treatment for patients with small cell lung cancer (SCLC); however, standard therapy has reached a plateau in improving patient survival with overall disappointing results. The demonstration that SCLC expresses neuroendocrine markers, such as somatostatin (SST) receptors, has led to use SST analogs or radiolabeled SST analogs in the treatment of SCLC patients. In the current review, we would focus on the possible role of SST analogs in SCLC.

Abstract
INTRODUCTION Circulating tumor cells (CTCs) can be isolated from the peripheral blood of cancer patients. Several studies to assess the prognostic and/or predictive role of CTCs have been performed in lung cancer patients. AREAS COVERED The state-of-the-art of the role of CTCs in lung cancer patients is reviewed and discussed. A structured search of bibliographic databases for peer-reviewed research literature and of main meetings using a focused review question was undertaken. Expert commentary: Although in the revised studies different technologies, cutoffs, patients' populations and statistical approaches have been used, a high CTCs count as prognostic role in small-cell lung cancer is suggested, whereas additional studies are required to confirm this correlation in non-small-cell lung cancer. A reduction in CTCs count is also likely to be correlated with the lung cancer patients' outcome. Large prospective trials need to confirm the prognostic and/or predictive role of CTCs in lung cancer.

Abstract
With 5-year survival rates below 5%, small cell lung carcinoma (SCLC) has very poor prognosis and requires improved therapies. Despite an excellent overall response to first-line therapy, relapses are frequent and further treatments are disappointing. The goal of the study was to improve second-line therapy of SCLC. The effect of chemotherapeutic agents was evaluated in cell lines (apoptosis, reactive oxygen species, and RNA and protein expression) and in mouse models (tumour development). We demonstrate here that valproic acid, a histone deacetylase inhibitor, improves the efficacy of a second-line regimen (vindesine, doxorubicin and cyclophosphamide) in SCLC cells and in mouse models. Transcriptomic profiling integrating microRNA and mRNA data identifies key signalling pathways in the response of SCLC cells to valproic acid, opening new prospects for improved therapies.

Abstract
Small cell lung cancer (SCLC) is one of the most malignant cancers in the world and 5-year survival rate has not been significantly improved with conventional chemotherapy. Targeting treatment may be a promising alternative to enhance the antitumor efficacy. Present study was aimed at establishing a targeting nanodrug delivery system for SCLC therapy. A targeting peptide (AHSGMYP, named AP), screened in H446 cells by phage display technology, was conjugated to the docetaxel (DTX) encapsulated polylactic acid nanoparticles (DN) to prepare the targeting DTX nanoparticles (AP-DN). Cell cytotoxicity, cellular uptake, therapeutic efficacy and biodistribution of AP-DN were investigated in vitro and in vivo experiment. The mean particle size of AP-DN was 260 nm with encapsulation efficiency >94% and a sustained release profile. Cytotoxicity of AP-DN against H446 cell was superior to that of DTX and DN. AP-DN exhibited excellent antitumor efficacy and particularly effectively inhibited the liver metastases with better tolerance. Results of cellular uptake and biodistribution indicated that the excellent antitumor efficacy of AP-DN was attributed to both the increased accumulation of drug and cellular uptake. To our knowledge, this is the first report on establishing SCLC targeting delivery system which offers a potential therapeutic alterative for SCLC therapy.

Abstract
BACKGROUND Small cell lung cancer (SCLC) is a recalcitrant malignancy with distinct biologic properties. Antibody targeting therapy has been actively investigated as a new drug modality. METHODS We tested the expression of IGF-1R and calculated the survival in 61 SCLC patients. We also evaluated the anti-tumor effects of anti-IGF-1R monoclonal antibody Figitumumab (CP) on SCLC, and tried two drug combinations to improve CP therapy. RESULTS Our clinical data suggested that high IGF-1R expression was correlated with low SCLC patient survival. We then demonstrated the effect of CP was likely through IGF-1R blockage and down-regulation without IGF-1R auto-phosphorylation and PI3K/AKT activation. However, we observed elevated MEK/ERK activation upon CP treatment in SCLC cells, and this MEK/ERK activation was enhanced by ß-arrestin1 knockdown while attenuated by ß-arrestin2 knockdown. We found both MEK/ERK inhibitor and metformin could enhance CP treatment in SCLC cells. We further illustrated the additive effect of metformin was likely through promoting further IGF-1R down-regulation. CONCLUSION Our results highlighted the potential of anti-IGF-1R therapy and the adjuvant therapy strategy with either MEK/ERK inhibitor or metformin to target SCLC, warranting further studies.

Abstract
Small cell lung cancer (SCLC) accounts for 15% of lung cancer cases and is associated with a dismal prognosis. Standard therapeutic regimens have been improved over the past decades, but without a major impact on patient survival. The development of targeted therapies based on a better understanding of the molecular basis of the disease is urgently needed. At the genetic level, SCLC appears very heterogenous, although somatic mutations targeting classical oncogenes and tumor suppressors have been reported. SCLC also possesses somatic mutations in many other cancer genes, including transcription factors, enzymes involved in chromatin modification, receptor tyrosine kinases and their downstream signaling components. Several avenues have been explored to develop targeted therapies for SCLC. So far, however, there has been limited success with these targeted approaches in clinical trials. Further progress in the optimization of targeted therapies for SCLC will require the development of more personalized approaches for the patients.

Abstract
Small-cell lung cancer (SCLC) easily recurs with multidrug resistance phenotype. However, standard therapeutic strategies for relapsed-SCLC remain unestablished. Human epidermal growth factor receptor 2 (HER2) expression correlates with poor prognosis in extensive disease-SCLC. We have reported previously that HER2 expression is upregulated when HER2-positive SCLC cells acquire chemoresistance, and also demonstrated that trastuzumab exerts significant antitumor activity toward HER2-upregulated chemoresistant SCLC, mainly via antibody-dependent cell-mediated cytotoxicity mechanism. Based on these preclinical data, we treated two patients with HER2-positive SCLC by combination of trastuzumab (6 mg/kg, day 1) and irinotecan (80 mg/m(2), days 1 and 8) every 21 days as the third-line chemotherapy following two prior regimens, first-line carboplatin plus etoposide and second-line amrubicin. One patient achieved partial response after the first cycle and received 6 cycles in total without disease progression for 4.5 months. The other also received 4 cycles and kept stable disease for 3.5 months. This treatment can be continued safely at an outpatient clinic without any severe adverse event. In conclusion, trastuzumab plus irinotecan chemotherapy is promising and feasible against HER2-positive relapsed SCLC. Further clinical studies are encouraged to confirm the antitumor efficacy of trastuzumab in SCLC.

Abstract
There is increasing evidence for the use of circulating tumor cells (CTCs) as a "liquid biopsy" for early detection of lung cancer recurrence, prognosticating disease and monitoring treatment response. Further, CTC molecular analysis and interrogation of single cells hold significant potential in providing insights into tumor biology and the metastatic process. Ongoing research will likely see the translation of CTCs as a prognostic and predictive biomarker in both small cell, and non-small cell, lung cancer to routine clinical practice.

Abstract
Poly (ADP) ribose polymerase (PARP) plays a key role in DNA repair and is highly expressed in small cell lung cancer (SCLC). We investigated the therapeutic impact of PARP inhibition in SCLC. In vitro cytotoxicity of veliparib, cisplatin, carboplatin, and etoposide singly and combined was determined by MTS in 9 SCLC cell lines (H69, H128, H146, H526, H187, H209, DMS53, DMS153, and DMS114). Subcutaneous xenografts in athymic nu/nu mice of H146 and H128 cells with relatively high and low platinum sensitivity, respectively, were employed for in vivo testing. Mechanisms of differential sensitivity of SCLC cell lines to PARP inhibition were investigated by comparing protein and gene expression profiles of the platinum sensitive and the less sensitive cell lines. Veliparib showed limited single-agent cytotoxicity but selectively potentiated (≥50% reduction in IC50) cisplatin, carboplatin, and etoposide in vitro in five of nine SCLC cell lines. Veliparib with cisplatin or etoposide or with both cisplatin and etoposide showed greater delay in tumor growth than chemotherapy alone in H146 but not H128 xenografts. The potentiating effect of veliparib was associated with in vitro cell line sensitivity to cisplatin (CC = 0.672; P = 0.048) and DNA-PKcs protein modulation. Gene expression profiling identified differential expression of a 5-gene panel (GLS, UBEC2, HACL1, MSI2, and LOC100129585) in cell lines with relatively greater sensitivity to platinum and veliparib combination. Veliparib potentiates standard cytotoxic agents against SCLC in a cell-specific manner. This potentiation correlates with platinum sensitivity, DNA-PKcs expression and a 5-gene expression profile.

Abstract
Given the large socio-economic burden of cancer, there is an urgent need for in vivo animal cancer models that can provide a rationale for personalised therapeutic regimens that are translatable to the clinic. Recent developments in establishing mouse models that closely resemble human lung cancers involve the application of genetically engineered mouse models (GEMMs) for use in drug efficacy studies or to guide patient therapy. Here, we review recent applications of GEMMs in non-small cell lung cancer research for drug development and their potential in aiding biomarker discovery and understanding of biological mechanisms behind clinical outcomes and drug interactions.

Abstract
Although advances in cancer therapies continue to develop, the shortness of the survival of lung cancer patients is still disappointing. Therefore, finding new adjuvant strategies is within the focus of cancer cure. Based on observations that deuterium depletion inhibits the growth of cancer cell lines and suppresses certain proto-oncogenes, we have conducted a clinical study in 129 patients with small cell and nonsmall cell lung cancers who consumed deuterium-depleted drinking water (DDW) as a nontoxic agent in addition to conventional chemotherapy and radiotherapy. Median survival time (MST) was 25.9 mo in males and 74.1 mo in female patients; the difference between genders was statistically significant (p < 0.05). Median survival of subjects with brain metastasis was 27.1 mo. Cumulative 5-yr survival probabilities were 19%, 52%, and 33% in males, females, and all patients with brain metastasis, respectively. Gene expression analysis in mouse lung indicated that DDW attenuates 7,12-dimethylbenz(a)anthracene (DMBA)-induced expression of Bcl2, Kras, and Myc in females. In conclusion, DDW counteracts the DMBA-induced overexpression of Bcl2, Kras and Myc genes in mouse lung, and it may extend survival of lung cancer patients as a nontoxic anticancer dietary supplement, especially for women with tumors overexpressing cancer-related genes, because MST of DDW-consuming group was 2-4 times longer than it is generally observed in lung cancer patients.

Abstract
SUMMARY Small-cell lung cancer (SCLC) accounts for approximately 15% of all new lung cancer diagnoses. The therapeutic approach is based according to the two-stage classification: limited-stage (LS) and extensive-stage (ES) disease. In LS-SCLC, concomitant radiochemotherapy, followed in nonprogressing patients by prophylactic cranial irradiation, is the standard of care. In ES-SCLC, chemotherapy is the cornerstone treatment, followed in patients who do not progress by prophylactic cranial irradiation. Platinum/etoposide is the regimen that has been used in both stages since the 1980s. This review focuses on the current state-of-the-art treatment of LS- and ES-SCLC and on specific questions that can be addressed to improve their outcomes, and looks at possible future developments.

Abstract
INTRODUCTION Therapeutic options for patients with relapsed, chemo-resistant small-cell lung cancer (SCLC) are limited. Since paclitaxel has demonstrated single-agent activity in the second-line setting of SCLC and angiogenesis seems to play an important role in the pathogenesis of the disease, a phase II trial was conducted in order to evaluate the efficacy and the tolerance of their combination in patients with relapsed, chemo-resistant SCLC. PATIENTS AND METHODS Patients with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 who experienced relapse within 3 months after completion of 1st line chemotherapy for SCLC were eligible. Patients were treated with paclitaxel (90 mg/m(2), days 1, 8 and 15) along with bevacizumab (10mg per kg of body weight, days 1 and 15) in cycles of 28 days. RESULTS Thirty patients (male/female: 27/3) with a median age of 64 years and ECOG performance status 0/1/2: 2/25/3 were enrolled. Nineteen patients (63.3%) had received at least two lines of prior treatment, 17 (56.7%) had undergone prior radiotherapy and nine (30%) had brain metastases at the time of study entry. The overall objective response rate was 20% (95% CI: 5.69-34.31%), including one complete remission, whereas the disease control rate was 36.7%. The median duration of response was 2.5 months (range, 1.5-5.7), the median progression-free survival 2.7 months (range, 0.5-9.2) and the median overall survival 6.3 months (range, 0.5-17.9). Grades 3 and 4 toxicities were limited in neutropenia, diarrhea and fatigue. There was one case of non-fatal pulmonary embolism. CONCLUSIONS The combination of paclitaxel with bevacizumab was feasible and active in this poor prognosis and heavily pretreated population of patients with advanced, chemoresistant SCLC, representing a valid therapeutic alternative which merits further evaluation.

Abstract
The incidence and mortality of small-cell lung cancer worldwide make this disease a notable health-care issue. Diagnosis relies on histology, with the use of immunohistochemical studies to confirm difficult cases. Typical patients are men older than 70 years who are current or past heavy smokers and who have pulmonary and cardiovascular comorbidities. Patients often present with rapid-onset symptoms due to local intrathoracic tumour growth, extrapulmonary distant spread, paraneoplastic syndromes, or a combination of these features. Staging aims ultimately to define disease as metastatic or non-metastatic. Combination chemotherapy, generally platinum-based plus etoposide or irinotecan, is the mainstay first-line treatment for metastatic small-cell lung cancer. For non-metastatic disease, evidence supports early concurrent thoracic radiotherapy. Prophylactic cranial irradiation should be considered for patients with or without metastases whose disease does not progress after induction chemotherapy and radiotherapy. Despite high initial response rates, most patients eventually relapse. Except for topotecan, few treatment options then remain. Signalling pathways have been identified that might yield new drug targets.

Abstract
Small cell carcinoma of the uterine cervix (SCCUC) is rare and its biologic behavior is aggressive. To analyze prognostic factors and determine optimal therapy in patients with International Federation of Gynecology and Obstetrics (FIGO) stage IB1-IIA SCCUC, we retrospectively reviewed 96 patients (14 patients treated in our center and 82 patients identified by a search on PubMed) treated with radical surgery (SU), surgery plus adjuvant chemotherapy (SU+Chemo), or surgery plus adjuvant chemotherapy and radiotherapy (SU+Chemo+RT) between 1990 and 2010. Of the 96 patients, 11 patients were treated with SU, 33 with SU+Chemo, and 52 with SU+Chemo+RT. The 5-year survival rate for the 96 patients was 45%. A total of 6% (2/32) of patients had local recurrence, 75% (24/32) had distant metastases, and 19% (6/32) had both. The 5-year survival rate in stage IB1 and IB2-IIA disease was 58 and 34%, respectively (P=0.049). For patients with and without lymph node metastases (LNM), survival was 33 and 60%, respectively (P=0.045). Patients with inner 1/3 stromal invasion had a better survival than those with deep stromal invasion (DSI) (100 vs. 34%, P=0.003). Survival was not significantly different in patients treated with the above three modalities, albeit treatment selection was related to LNM (P=0.000) and DSI (P=0.027). Thus, FIGO stage, LNM and DSI are significant predictors of survival. Adjuvant therapy after SU has not improved survival compared with surgery alone. Thus, newer multimodality therapy should be evaluated.

Abstract
Background Small-cell lung carcinoma (SCLC) is an aggressive malignancy characterised by an early relapse, a tendency towards drug resistance, and a high incidence of metastasis. SCLC cells are of neuroendocrine origin and express high levels of somatostatin receptors; therefore, future treatment might involve targeting tumours with radiolabelled somatostatin analogues. This therapy induces abundant necrotic patches that contain exposed keratins; thus, keratin 8, which is one of the most abundant cytoskeletal proteins may represent an interesting secondary target for SCLC. This study aimed to investigate the effects of177Lu-DOTA-Tyr3-octerotate and the binding of the monoclonal anti-keratin 8 antibody, TS1, in vitro in treated SCLC- and midgut-xenografted mouse models. Methods NCI-H69- and GOT1-xenotransplanted mice were treated with three doses of 30 MBq177Lu-DOTA-Tyr3-octreotate administered 24 h apart. Mice xenotransplanted with NCI-H69 were sacrificed 1, 5, 12, 20 and 150 days post-injection or when the tumour had regrown to its original size. GOT1-xenotransplanted mice were sacrificed 3 days post-injection. Immunohistochemistry was performed to evaluate TS1 staining in tumours and in seven human biopsies of primary SCLC from pulmonary bronchi. Central cell density and nucleus size were determined in NCI-H69 sections. Results Twelve days after177Lu-DOTA-Tyr3-octerotate treatment, the SCLC xenograft response was extensive. Twenty days after treatment, one of three analysed tumours displayed complete remission. The other two tumours showed 1/4 the cell density of untreated controls and cell nuclei were about three times larger than those of untreated controls. At 150 days after treatment, one of four mice exhibited complete remission. Treated tumours displayed increased TS1 antibody accumulation and high TS1 binding in necrotic patches. All seven human SCLC biopsies displayed necrotic areas with TS1 staining. Conclusions Radiation treatment with three injections of 30 MBq177Lu-DOTA-Tyr3-octreotate had pronounced effects on tumour cell density and cell nuclei, which indicated mitotic catastrophe. Despite these anti-tumour effects, two of three SCLC tumours recurred. Further studies should investigate the nature of tumour cell survival and develop more effective treatments. High TS1 accumulation in tumour sections in vitro after177Lu-DOTA-Tyr3-octerotate treatment indicated that TS1 might represent a promising secondary therapeutic strategy.

Abstract
OBJECTIVE To determine the clinicopathologic factors associated with survival in neuroendocrine small cell cervical cancer patients. STUDY DESIGN Patients were identified from a review of literature with an additional 52 patients from four hospitals. Kaplan-Meier and Cox regression methods were used for analyses. RESULTS Of 188 patients, 135 had stages I-IIA, 45 stages IIB-IVA, and 8 stage IVB disease. A total of 55.3% underwent surgery, 16.0% had chemoradiation, 12.8% radiation, and 3.2% chemotherapy alone. The 5-year disease-specific survival in stage I-IIA, IIB-IVA, and IVB disease was 36.8%, 9.8%, and 0%, respectively (P < .001). Adjuvant chemotherapy or chemoradiation was associated with improved survival in patients with stages IIB-IVA disease compared with those who did not receive chemotherapy (17.8% vs 6.0%; P = .04). On multivariable analysis, early-stage disease and use of chemotherapy or chemoradiation were independent prognostic factors for improved survival. CONCLUSION Use of adjuvant chemotherapy or chemoradiation was associated with higher survival in small cell cervical cancer patients.

Abstract
Although the incidence of small cell lung cancer (SCLC) has declined during the past 30 years, it remains a significant cause of cancer mortality in the United States and across the world. With appropriate treatment, about 20% of patients who present with limited stage SCLC can be cured of their disease. Unfortunately, the outcome for the remainder of patients is extremely poor. The only significant advance in extensive stage SCLC in the past 2 decades is the recent discovery that prophylactic cranial irradiation improves survival in those patients whose disease has responded to initial chemotherapy. Numerous attempts to enhance the antitumor effects of traditional chemotherapy for SCLC have not been successful. As the understanding of the biology of SCLC increased, a number of rational molecular targets for therapy have been identified. Although initial attempts at "targeted therapy" in SCLC have been unsuccessful, several newly identified targets hold promise and give hope that significant improvements in therapy for this challenging disease are not far away.

Abstract
Background: Small-cell lung cancer is highly chemo- and radiosensitive tumor. We evaluated two different radiotherapy doses applied sequentially with chemotherapy in relation to time to progression, progression free survival, and overall survival in patients with limited disease of small cell lung cancer. Methods: From 1998 to 2003, 81 patients were treated for small-cell lung carcinoma. Median age was 57 years (range, 36-77 years) and female: male ratio was 1:4. Patients were initially treated with four cycles of chemotherapy during three weeks (cisplatin 80mg/m2 IV, day 1 and etoposide 100 mg/m2 IV, days 1 - 3). One month later, patients received up to 44 Gy, 2 Gy per day, 5 days per week (group I, 41 patients) or above 44 Gy, standard fractionation (group II, 40 patients), to mediastinum and tumor. Range of higher radiotherapy doses was 54 Gy to 64 Gy, standard fractionation. We evaluated if different radiotherapy doses had any influence on time to progression, progression free survival, and overall survival. Results: The median follow up time was 23 months (range, 12-72 months) for both groups of patients (81). The median time to progression in group I of patients (41) was 13 months (range, 11-29 months) while median time to progression in group II of patients (40) was 20 months (min=9, max=60). There was no statistically significant difference in relapse rate between two groups of patients (p>0.05, Fisher test). However, there was difference but not statistically significant in one-year progression free survival (p=0.05, chi square test) between groups, while there was statistically significant difference in two-year progression free survival favoring higher doses of radiotherapy (p<0.05, chi-square test). The median overall survival was 18 months (range, 12-35 months) for group I of patients and 28 months (range, 15-72 months) for group II of patients. There was no statistically significant advantage between two groups of patients for one-year overall survival (p>0.05, chi-square test). However, there was statistically significant difference in overall survival favoring higher radiotherapy doses for two-year overall survival (p<0.05, chi-square test). Conclusion: We found that higher radiotherapy doses had an impact on long-term time to progression, progression free survival, and overall survival (2 years) of patients.

Abstract
Protoapigenone, isolated from the native fern plant Thelypteris torresiana, has anticancer activity against some cancer cells. However, the toxicological mechanism for protoapigenone is still unknown. Here, we investigated the anticancer effect of protoapigenone on human lung cancer cell lines. The comet assay showed that DNA damage induced by protoapigenone is dose-dependent. Trypan blue exclusion showed that the cell killing by protoapigenone is both time and dose dependent. The IC(50) of protoapigenone for 12, 24, and 48 h in H1299 cells is 6.11, 2.74, and 1.49 microM, respectively. Flow cytometry showed cell cycle perturbation such as sub-G(1) accumulation (at 1.57 microM for 48 h and at 3.57 microM for 12 and 24 h) and G(2)/M arrest (at 3.57 microM for 12 and 24 h) for protoapigenone. The sub-G(1) accumulation phenomena in the 3.57 microM for 24 h sample were shown to be apoptosis using Annexin V-immunofluorescence/propidium iodide staining. These results suggest protoapigenone is a potential chemotherapeutic agent for lung cancers.
