Lambrecht L, Arnold P, Behr J, Mertsch P, Tufman A, Kauffmann-Guerrero D. Topotecan in a Real-World Small-Cell Lung Cancer Cohort: Prognostic Biomarkers Improve Selection of Patients for Second-Line Treatment. Diagnostics (Basel) 2024; 14:1572. [PMID: 39061709 PMCID: PMC11276225 DOI: 10.3390/diagnostics14141572] [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: 06/02/2024] [Revised: 07/15/2024] [Accepted: 07/18/2024] [Indexed: 07/28/2024] Open
Abstract
BACKGROUND Small-cell lung cancer (SCLC) is a highly aggressive tumor, and overall survival (OS) remains poor despite intensive efforts to develop new treatment strategies. In second line, topotecan is the only approved drug, with a median OS of 5.9 months. However, real-world SCLC patients are often in worse condition and harbor more comorbidities than study populations. Therefore, the real-world performance of topotecan may differ from that seen in studies. Here, we analyzed outcomes of SCLC patients receiving topotecan and identified predictive and prognostic markers. PATIENTS AND METHODS We retrospectively analyzed 44 consecutive SCLC patients receiving topotecan between 2015 and 2022. We analyzed baseline characteristics (age, ECOG-PS, topotecan cycles, and dosage) and pre-treatment blood values (LDH, CRP, sodium) as well as prognostic scores (neutrophil/lymphocyte ratio (NLR), thrombocyte/lymphocyte ratio (TLR), Glasgow Prognostic Score, prognostic nutritional score, systemic inflammation index (SII), and the prognostic index) extracted from electronic patients' charts to identify predictive and prognostic markers. RESULTS In our cohort, mPFS and mOS were only 1.9 and 5.6 months, respectively. Gender, ECOG-PS, active brain metastases, NLR, GPS, PNI, and SII significantly influenced PFS and OS in univariate analysis. ECOG-PS (p > 0.001), active brain metastases (p = 0.001), and SII (p = 0.008) were significant independent prognostic variables in a multivariate COX regression model. Selecting patients by these three markers achieved an mPFS of 5.7 months and thus increased the mPFS three-fold. Patients not meeting all criteria had an mPFS of 1.8 months (p = 0.006). Patients identified by prognostic markers had an mOS of 9.1 months (p = 0.002). CONCLUSIONS The efficacy of topotecan in SCLC real-world patients is poor, indicating that many patients were treated without any benefit. Easy-to-obtain markers can predict response and treatment efficacy and should therefore be validated in larger cohorts to identify patients who are more likely to benefit from topotecan.

Abstract
Lung cancer is the most malignant human cancer worldwide, also with the highest incidence rate. However, small-cell lung cancer (SCLC) accounts for 14 % of all lung cancer cases. Approximately 10 % of patients with SCLC have brain metastasis at the time of diagnosis, which is the leading cause of death of patients with SCLC worldwide. The median overall survival is only 4.9 months, and a long-tern cure exists for patients with SCLC brain metastasis due to limited common therapeutic options. Recent studies have enhanced our understanding of the molecular mechanisms leading to meningeal metastasis, and multimodality treatments have brought new hopes for a better cure for the disease. This review aimed to offer an insight into the cellular processes of different metastatic stages of SCLC revealed by the established animal models, and into the major diagnostic methods of SCLC. Additionally, it provided in-depth information on the recent advances in SCLC treatments, and highlighted several new models and biomarkers with promises to improve the prognosis of SCLC.

Real-life second-line epirubicin-paclitaxel regimen as treatment of relapsed small-cell lung cancer: EpiTax study. Cancer Med 2022; 12:2658-2665. [PMID: 36000584 PMCID: PMC9939142 DOI: 10.1002/cam4.5143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 08/02/2022] [Accepted: 08/05/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Few therapeutic options are approved as second-line treatment after failure of platinum-based chemotherapy for patients with extensive-stage small-cell lung cancer (ES-SCLC). Topotecan widespread use remains challenged by the risk of severe toxicities in a pretreated population. Little is known about the efficacy and safety of epirubicin-paclitaxel doublet in second-line and beyond and especially cerebral outcomes. METHODS EpiTax is a retrospective multicenter observational real-life study. We evaluated the efficacy of epirubicin 90 mg/m2 combined with paclitaxel 175 mg/m2 every 3 weeks in SCLC patients after failure of at least one line of platinum-based chemotherapy. The primary endpoint was progression-free survival (PFS). Secondary endpoints were overall survival (OS), objective response rate (ORR), disease control rate (DCR), intracranial control rate (ICR), and safety. RESULTS A total of 29 patients were included. The median of previous systemic therapy lines was 2 (1-4). Eleven patients received the treatment in the second line. Characteristics of patients were a median age of 60 years (45-77), 65.5% of males with 72.4% of PS 0-1. Fifteen patients had a history of brain metastases. Median PFS and OS achieved 11.0 (95% CI, 8.1-16.3) and 23 (95% CI, 14.1-29.6) weeks, respectively. ORR was 34.5% and DCR was 55.2%. ICR was 3/15 (20%). Grade 3-4 adverse events were mainly hematological and concerned 7 patients. No case of febrile neutropenia or toxic death was reported. CONCLUSION Epirubicin-paclitaxel association highlighted promising efficacy with PFS and OS of 11 and 23 weeks, respectively, ORR of 34.5%, and a tolerable safety profile. This doublet could represent another valuable therapeutic option for ES-SCLC patients treated in the second line and beyond.

Abstract
Brain metastases (BrM) are common in both non-small-cell lung cancer and small-cell lung cancer. Substantial progress in BrM management has occurred in the past decade related to advances in both radiation and medical oncology. Recent and ongoing radiation trials have focused on increasing the candidacy for focal therapy of BrM with stereotactic radiosurgery; reducing the toxicity and improving patient selection for whole brain radiotherapy; and, in small-cell lung cancer, evaluating brain magnetic resonance imaging surveillance without prophylactic cranial irradiation, hippocampal avoidance in prophylactic cranial irradiation and whole brain radiotherapy, and the role of upfront stereotactic radiosurgery for BrM. In medical oncology, the development of multiple tyrosine kinase inhibitors with encouraging CNS activity and emerging data on the CNS activity of immune checkpoint inhibitors in some patients have opened the door to novel systemic and multidisciplinary treatment strategies for the management of BrM. Future research will focus on more robust characterizations of the CNS activity of targeted therapy and immunotherapies, as well as optimal integration and patient selection for multidisciplinary strategies involving CNS-active drugs, radiation therapy, and CNS surveillance.

Abstract
Stem cell therapy may present an effective treatment for metastatic brain cancer and glioblastoma. Here we posit the critical role of a leaky blood-brain barrier (BBB) as a key element for the development of brain metastases, specifically melanoma. By reviewing the immunological and inflammatory responses associated with BBB damage secondary to tumoral activity, we identify the involvement of this pathological process in the growth and formation of metastatic brain cancers. Likewise, we evaluate the hypothesis of regenerating impaired endothelial cells of the BBB and alleviating the damaged neurovascular unit to attenuate brain metastasis, using the endothelial progenitor cell (EPC) phenotype of bone marrow-derived mesenchymal stem cells. Specifically, there is a need to evaluate the efficacy for stem cell therapy to repair disruptions in the BBB and reduce inflammation in the brain, thereby causing attenuation of metastatic brain cancers. To establish the viability of stem cell therapy for the prevention and treatment of metastatic brain tumors, it is crucial to demonstrate BBB repair through augmentation of vasculogenesis and angiogenesis. BBB disruption is strongly linked to metastatic melanoma, worsens neuroinflammation during metastasis, and negatively influences the prognosis of metastatic brain cancer. Using stem cell therapy to interrupt inflammation secondary to this leaky BBB represents a paradigm-shifting approach for brain cancer treatment. In this review article, we critically assess the advantages and disadvantages of using stem cell therapy for brain metastases and glioblastoma.

Abstract
PURPOSE OF REVIEW Management of metastasis to the central nervous system (CNS) has evolved, and molecular characterization of metastatic disease is now routinely done. Targeted therapies, once few in number with limited penetration into the CNS, have multiplied in number and increased in CNS coverage. This article addresses recent advances in the evaluation and clinical management of patients with CNS metastasis. RECENT FINDINGS Metastasis of cancer to the CNS can be diagnosed and characterized with novel techniques, including molecular analyses of the spinal fluid, so-called liquid biopsies. Resected parenchymal CNS metastases are now routinely subjected to genomic sequencing. For patients with CNS metastases displaying targetable mutations, a wide variety of treatment options are available, including deferral of radiation therapy in favor of a trial of an orally bioavailable targeted therapy or immunotherapy. For patients without a molecularly targetable lesion, local treatment in the form of radiation therapy, now most often stereotactic radiosurgery, is supplanting untargeted whole-brain radiation therapy. SUMMARY Technologic advances in diagnosis and management have resulted in new diagnostic and therapeutic approaches to patients with metastasis to the CNS, with resulting improvements in progression-free and overall survival.

Synchronized Ratiometric Codelivery of Metformin and Topotecan through Engineered Nanocarrier Facilitates In Vivo Synergistic Precision Levels at Tumor Site. Adv Healthc Mater 2018; 7:e1800300.

Abstract
The combination of metabolic modulators with chemotherapy holds vast promise for effective inhibition of tumor progression and invasion. Herein, a ratiometric codelivery platform is developed for metformin (MET), a known metabolic modulator and topotecan (TPT), a chemotherapeutic drug, by engineering lipid bilayer-camouflaged mesoporous silica nanoparticles (LB-MSNs). In an attempt to deliver and maintain high tumor site concentrations of MET and TPT, a novel ion pairing-assisted loading procedure is developed using pamoic acid (PA) as an in situ trapping agent. PA, a hydrophobic counterion, increases the hydrophobicity of MET and TPT and facilitates MSNs with exceptionally high payload capacity (>40 and 32 wt%, respectively) and controlled release profile. Further, the synergy between MET and TPT determined by a modeling approach helps to afford synchronized delivery of both the drugs. Coloaded MET and TPT LB-MSNs present synergistic cytotoxicity against MDA-MB-231/4T1 cells and effectively promote apoptosis via mitochondrial membrane depolarization and cell cycle arrest. Extended pharmacokinetic profiles in preclinical models with fourfold to sevenfold longer circulation half-life and 7.5-100 times higher tumor site concentrations correspond to a significant increase in pharmacodynamic efficacy. Taken together, the developed codelivery approach effectively addresses the challenges in the chemotherapeutic efficacy of MET and TPT collectively.

Abstract
OPINION STATEMENT Treatment options for leptomeningeal metastases are expanding with greater tolerability and efficacy than in the past. Improved knowledge of molecular subtypes of some cancers can guide in choosing more effective therapeutic options; however, physicians should be mindful that these molecular types can be different in the central nervous system compared to the rest of the body. This is particularly true in breast and lung cancer, in which some patients now can live for many months or even years after diagnosis of leptomeningeal metastases. Options for intrathecal therapies are expanding, but physicians should be mindful that this is a passive delivery system that relies on normal CSF flow, so therapies will not penetrate bulky or parenchymal disease sites, especially in the presence of abnormal CSF flow. When chemotherapeutic options are lacking or unsuccessful, focal radiosurgery which can provide symptomatic relief and proton craniospinal radiation remain effective options. Hopefully more formal studies will be conducted in the future to verify which treatments are indeed most effective for particular types of cancer.

Abstract
Brain metastases are very common in lung cancer patients. The condition of these patients is complicated and difficult to treat, and adverse reactions following treatment can affect the nervous system, which severely reduces quality of life. Lung cancers are categorized as small cell lung cancers and non-small cell lung cancers. Patients with brain metastasis of small cell lung cancers are generally treated with brain radiotherapy and systemic chemotherapy, but stage III/IV patients with brain metastasis of non-small cell lung cancers are generally not responsive to radiotherapy or chemotherapy. With the recent development of targeted drugs, tumor molecular profile detection allows the selection of appropriate targeted drugs for adjuvant pharmacological treatment of brain metastasis in lung cancer patients. In recent years, immune checkpoint inhibitors have emerged and have been approved by the Food and Drug Administration (FDA) for the treatment of certain cancers, but their efficacy in lung cancer patients with brain metastases still needs to be confirmed. This paper focuses on highlighting drugs for targeted therapy of brain metastasis in lung cancer patients and their molecular targets and mechanisms of drug resistance.

Abstract
Medulloblastoma (MB) is the most common childhood brain tumor, which occurs in the posterior fossa. MB tumors are highly heterogeneous and have diverse genetic make-ups, with differential microRNA (miRNA) expression profiles and variable prognoses. MB can be classified into four subgroups, each with different origins, pathogenesis, and potential therapeutic targets. miRNA and small-molecule targeted therapies have emerged as a potential new therapeutic paradigm in MB treatment. However, the development of chemoresistance due to surviving cancer stem cells and dysregulation of miRNAs remains a challenge. Combination therapies using multiple drugs and miRNAs could be effective approaches. In this review we discuss various MB subtypes, barriers, and novel therapeutic options which may be less toxic than current standard treatments.

Abstract
BACKGROUND Small cell lung cancer (SCLC) frequently leads to development of brain metastases. These unfortunately continue to be associated with short survival. Substantial advances have been made in our understanding of the underlying biology of disease. This understanding on the background of previously evaluated and currently utilized therapeutic treatments can help guide the next steps in investigations into this disease with the potential to influence future treatments. DESIGN A comprehensive review of the literature covering epidemiology, pathophysiology, imaging characteristics, prognosis, and therapeutic management of SCLC brain metastases was performed. RESULTS SCLC brain metastases continue to have a poor prognosis. Both unique aspects of SCLC brain metastases as well as features seen more universally across other solid tumor brain metastases are discussed. Systemic therapeutic studies and radiotherapeutic approaches are reviewed. CONCLUSIONS A clearer understanding of SCLC brain metastases will help lay the framework for studies which will hopefully translate into meaningful therapeutic options for these patients.

Abstract
Lung cancer continues to be the leading cause of cancer-related mortality in the United States. Brain metastases are a significant problem in patients with lung cancer and have conventionally been treated with whole-brain radiation. This article reviews the data for systemic chemotherapy to treat brain metastasis from lung cancer and examines the activity of small molecule tyrosine kinase inhibitors for the targeted therapy for brain metastases from EGFR-mutant and ALK-rearranged non-small cell lung cancer. Future directions for evaluating the role of immunotherapy in treating brain metastasis are also discussed.

Outcome and prognostic factors in patients with brain metastases from small-cell lung cancer treated with whole brain radiotherapy. J Neurooncol 2017; 134:205-212. [PMID: 28560661 DOI: 10.1007/s11060-017-2510-0] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2017] [Accepted: 05/20/2017] [Indexed: 12/20/2022]
Abstract
The purpose of this study was to evaluate prognostic factors associated with overall survival (OS) and neurological progression free survival (nPFS) in small-cell lung cancer (SCLC) patients with brain metastases who received whole-brain radiotherapy (WBRT). From 2003 to 2015, 229 SCLC patients diagnosed with brain metastases who received WBRT were analyzed retrospectively. In this cohort 219 patients (95%) received a total photon dose of 30 Gy in 10 fractions. The prognostic factors evaluated for OS and nPFS were: age, Karnofsky Performance Status (KPS), number of brain metastases, synchronous versus metachronous disease, initial response to chemotherapy, the Radiation Therapy Oncology Group recursive partitioning analysis (RPA) class and thoracic radiation. Median OS after WBRT was 6 months and the median nPFS after WBRT was 11 months. Patients with synchronous cerebral metastases had a significantly better median OS with 8 months compared to patients with metachronous metastases with a median survival of 3 months (p < 0.0001; HR 0.46; 95% CI 0.31-0.67). Based on RPA classification median survival after WBRT was 17 months in RPA class I, 7 months in class II and 3 months in class III (p < 0.0001). Karnofsky performance status scale (KPS < 70%) was significantly associated with OS in both univariate (HR 2.84; p < 0.001) and multivariate analyses (HR 2.56; p = 0.011). Further, metachronous brain metastases (HR 1.8; p < 0.001), initial response to first-line chemotherapy (HR 0.51, p < 0.001) and RPA class III (HR 2.74; p < 0.001) were significantly associated with OS in univariate analysis. In multivariate analysis metachronous disease (HR 1.89; p < 0.001) and initial response to chemotherapy (HR 0.61; p < 0.001) were further identified as significant prognostic factors. NPFS was negatively significantly influenced by poor KPS (HR 2.56; p = 0.011), higher number of brain metastases (HR 1.97; p = 0.02), and higher RPA class (HR 2.26; p = 0.03) in univariate analysis. In this series, the main prognostic factors associated with OS were performance status, time of appearance of intracranial disease (synchronous vs. metachronous), initial response to chemotherapy and higher RPA class. NPFS was negatively influenced by poor KPS, multiplicity of brain metastases, and higher RPA class in univariate analysis. For patients with low performance status, metachronous disease or RPA class III, WBRT should be weighed against supportive therapy with steroids alone or palliative chemotherapy.

Abstract
Development of brain metastasis (BM) portends a dismal prognosis for patients with cancer. Melanomas and carcinomas of the lung, breast, and kidney are the most common malignancies to metastasize to the brain. Recent advances in molecular genetics have enabled the identification of actionable, clinically relevant genetic alterations within primary tumors and their corresponding metastases. Adoption of genotype-guided treatment strategies for the management of systemic malignancy has resulted in dramatic and durable responses. Unfortunately, despite these therapeutic advances, central nervous system (CNS) relapses are not uncommon. Although these relapses have historically been attributed to limited blood brain barrier penetration of anti-neoplastic agents, recent work has demonstrated genetic heterogeneity such that metastatic sites, including BM, harbor relevant genetic alterations that are not present in primary tumor biopsies. This improved insight into molecular mechanisms underlying site specific recurrences can inform strategies for targeting these oncogenic drivers. Thus, development of rational, genomically guided CNS-penetrant therapies is crucial for ongoing therapeutic success.

Abstract
Approximately half of all patients with non-small cell lung cancer (NSCLC) develop central nervous system metastases during the course of their disease which indicate poor prognosis. A part of NSCLC patients demonstrates activating epidermal growth factor receptor gene (EGFR) mutations who represent effectiveness and well tolerance of EGFR-specific tyrosine kinase inhibitors (TKIs) therapy. Although the systemic efficacy of targeted agents is established, the efficacy of central nervous system (CNS) metastases is not as well characterized. In this article, we review recent data on the use of EGFR inhibitors for treatment of patients with NSCLC and CNS metastases.

Abstract
Systemic treatment of lung cancer patients with brain metastases is based on clinical (presence of symptomatic intracranial lesions), pathological and molecular characteristics of the disease. The efficacy of standard platinum-based chemotherapy is comparable inside and outside the brain, justifying its use as front-line therapy. The intracranial efficacy of targeted therapies (EGFR tyrosine kinase inhibitors, ALK inhibitors) is demonstrated, and is globally superior to the efficacy of standard chemotherapy, justifying their use as front-line therapy in case of EGFR activating mutation or ALK rearrangement (providing the change in the crizotinib label in France). The concomitant use of whole brain radiotherapy and a systemic treatment (chemotherapy or targeted therapy) is not recommended in the absence of a demonstrated better efficacy and/or acceptable safety profile. Several trials are ongoing to assess new whole brain radiotherapy modalities, new targeted therapies alone or in combination, especially exploring immunotherapy.

Abstract
We propose that stem cell therapy may be a potent treatment for metastatic melanoma in the brain. Here we discuss the key role of a leaky blood-brain barrier (BBB) that accompanies the development of brain metastases. We review the need to characterize the immunological and inflammatory responses associated with tumor-derived BBB damage in order to reveal the contribution of this brain pathological alteration to the formation and growth of brain metastatic cancers. Next, we discuss the potential repair of the BBB and attenuation of brain metastasis through transplantation of bone marrow-derived mesenchymal stem cells with the endothelial progenitor cell phenotype. In particular, we review the need for evaluation of the efficacy of stem cell therapy in repairing a disrupted BBB in an effort to reduce neuroinflammation, eventually attenuating brain metastatic cancers. The demonstration of BBB repair through augmented angiogenesis and vasculogenesis will be critical to establishing the potential of stem cell therapy for the treatment/prevention of metastatic brain tumors. The overarching hypothesis we advanced here is that BBB breakdown is closely associated with brain metastatic cancers of melanoma, exacerbating the inflammatory response of the brain during metastasis, and ultimately worsening the outcome of metastatic brain cancers. Abrogating this leaky BBB-mediated inflammation via stem cell therapy represents a paradigm-shifting approach to treating brain cancer. This review article discusses the pros and cons of cell therapy for melanoma brain metastases.

Abstract
BACKGROUND Combination chemotherapy has been the mainstay of treatment for extensive stage small celI lung cancer (SCLC) over the last 30 years, even though it only gives a short prolongation in median survival time. The main goal for these patients should be palliation with the aim of improving their quality of life. OBJECTIVES To determine the effectiveness of first-line chemotherapy versus placebo or best supportive care (BSC) in prolonging survival in patients with extensive SCLC at diagnosis and the effectiveness of second-line chemotherapy at relapse or progression after first-line chemotherapy compared with BSC or placebo in prolonging survival in patients with extensive SCLC; as well as to evaluate the adverse events of treatment and the quality of life of patients. SEARCH METHODS This is the second update of the review. MEDLINE (1966 to October 2013), EMBASE (1974 to October 2013), and the Cochrane Central Register of Controlled Trials (CENTRAL) (2012, Issue 3) were searched. Experts in the field were contacted. SELECTION CRITERIA Phase III randomised controlled trials in which any chemotherapy treatment was compared with placebo or BSC in patients with extensive SCLC, as first-line or second-line therapy at relapse. DATA COLLECTION AND ANALYSIS Two authors independently extracted data and assessed study quality. We resolved disagreements by discussion. Additional information was obtained from one study author. MAIN RESULTS Two studies of unclear risk of bias were included for first-line chemotherapy. A total of 88 men under 70 years with good performance status were randomised to receive either supportive care, placebo infusion or ifosfamide. Ifosfamide gave an extra mean survival of 78.5 days compared with supportive care or placebo infusion. Partial tumour response was greater with the active treatment. Toxicity was only seen in the chemotherapy group and quality of life was only assessed at the beginning of treatment. The quality of the evidence for overall survival and adverse effects was very low.Three studies of moderate risk of bias were included for second-line chemotherapy at relapse (one identified in the last search). A total of 932 men and women under 75 years and any performance status were randomised to receive either methotrexate-doxorubicin, topotecan, or picoplatin versus symptomatic treatment or BSC. The methotrexate-doxorubicin treatment gave a median survival of 63 days longer than in the symptomatic-treatment group for patients allocated to receive four cycles of first-line chemotherapy, and 21 days longer for patients allocated to receive eight cycles of first-line chemotherapy.Treatment with topotecan gave a median survival of 84 days longer than in the BSC group (log-rank P = 0.01). The adjusted hazard ratio (HR) for overall survival was 0.61 (95% CI 0.43 to 0.87). Treatment with picoplatin gave a median survival time of six days longer than BSC (HR 0.817, 95% CI 0.65 to 1.03, P = 0.0895). A meta-analysis of topotecan and picoplatin gave a HR of 0.73 (95% CI 0.55 to 0.96, P = 0.03; low-quality evidence).Partial or complete response in the methotrexate-doxorubicin group was 22.3%. Five patients (7%, 95% CI 2.33 to 15.67) showed a partial response with topotecan. No data were provided about tumour response in the picoplatin study. Toxicity was worst in the chemotherapy group (moderate-quality evidence). Quality of life was better in the topotecan group and was not measured in the methotrexate-doxorubicin and picoplatin studies (low-quality evidence). AUTHORS' CONCLUSIONS Two small RCTs from the 1970s suggest that first-line chemotherapeutic treatment (based on ifosfamide) may provide a small survival benefit (less than three months) in comparison with supportive care or placebo infusion in patients with advanced SCLC. However platinum-based combination chemotherapy regimens have been shown to increase complete response rates when compared to non-platinum chemotherapy regimens with no significant difference in survival, and so these are currently the standard first-line treatment for patients with SCLC.Second-line chemotherapy at relapse or progression may prolong survival for some weeks in relation to BSC. Nevertheless, the impact of first-line chemotherapy on quality of life, older patients, women and patients with poor prognosis is unknown and the benefits of second-line chemotherapy are also unclear for older people. Globally, the evidence on which these conclusions are based is very scarce and of uncertain or low quality, which calls for well-designed, controlled trials to further evaluate the trade-offs between benefits and risks of different chemotherapeutic schedules in patients with advanced SCLC.

Abstract
BACKGROUND Patients with brain metastases from lung cancer have poor prognoses and short survival time, and they are often excluded from clinical trials. Whole-cranial irradiation is considered to be the standard treatment, but its efficacy is not satisfactory. The purpose of this phase II clinical trial was to evaluate the preliminary efficacy and safety of the treatment of whole-brain irradiation plus three-dimensional conformal boost combined with concurrent topotecan for the patients with brain metastases from lung cancer. METHODS Patients with brain metastasis from lung cancer received concurrent chemotherapy and radiotherapy: conventional fractionated whole-brain irradiation, 2 fields/time, 1 fraction/day, 2 Gy/fraction, 5 times/week, and DT 40 Gy/20 fractions; for the patients with ≤ 3 lesions with diameter ≥ 2 cm, a three-dimensional (3-D) conformal localised boost was given to increase the dosage to 56-60 Gy; and during radiotherapy, concurrent chemotherapy with topotecan was given (the chemoradiotherapy group, CRT). The patients with brain metastasis from lung cancer during the same period who received radiotherapy only were selected as the controls (the radiotherapy-alone group, RT). RESULTS From March 2009 to March 2012, both 38 patients were enrolled into two groups. The median progression-free survival(PFS) time , the 1- and 2-year PFS rates of CRT group and RT group were 6 months, 42.8%, 21.6% and 3 months, 11.6%, 8.7% (χ2 = 6.02, p = 0.014), respectively. The 1- and 2-year intracranial lesion control rates of CRT and RT were 75.9% , 65.2% and 41.6% , 31.2% (χ2 = 3.892, p = 0.049), respectively. The 1- and 2-year overall survival rates (OS) of CRT and RT were 50.8% , 37.9% and 40.4% , 16.5% (χ2 = 1.811, p = 0.178), respectively. The major side effects were myelosuppression and digestive toxicities, but no differences were observed between the two groups. CONCLUSION Compared with radiotherapy alone, whole-brain irradiation plus 3-D conformal boost irradiation and concurrent topotecan chemotherapy significantly improved the PFS rate and the intracranial lesion control rate of patients with brain metastases from lung cancer, and no significant increases in side effects were observed. Based on these results, this treatment method is recommended for phase III clinical trial.

Abstract
BACKGROUND The efficacy and limitations of salvage gamma knife surgery (GKS) have not been thoroughly described. This study evaluated the efficacy of GKS for treating brain metastases associated with small-cell lung cancer (SCLC) after whole-brain radiotherapy (WBRT) as the first-line radiation therapy. METHODS Forty-four patients with recurrent or new SCLC-associated brain metastases underwent GKS after receiving WBRT (median age, 62 years; median duration between WBRT and first GKS, 8.8 months). The median Karnofsky performance status (KPS) score was 100 (range, 40-100), and the median number of brain metastases at the first GKS was five. Ten patients who partially or completely responded to chemotherapy received prophylactic cranial irradiation (PCI) for limited disease. RESULTS The median prescribed dose and number of lesions treated with the initial GKS were 20.0 Gy and 3.5, respectively, and the tumor control rate was 95.8 % (median follow-up period, 4.0 months). The 6-month new lesion-free survival, functional preservation rates, and overall survival were 50.0 %, 94.7 %, and 5.8 months, respectively. Neurological death occurred in 17.9 % of cases. The poor prognostic factors for new lesion-free survival time and functional preservation were >5 brain metastases and carcinomatous meningitis, respectively. Poor prognostic factors for survival time were KPS <70, >10 brain metastases, diameter of the largest tumor >20 mm, and carcinomatous meningitis. Median overall survival time from brain metastasis diagnosis was 16.9 months. CONCLUSIONS GKS may be an effective option for controlling SCLC-associated brain metastases after WBRT and for preventing neurological death in patients without carcinomatous meningitis.

Abstract
Lung cancer represents the most common cause of cancer-related mortality in the United States and around the world. DNA topoisomerase I (TOP1) drugs such as irinotecan and topotecan represent a unique class of chemotherapeutic agents that exhibit not only potent cytotoxic effect, but also tumor-selective radiation-sensitizing effect. The mechanism of cytotoxicity and radiation sensitization by TOP1 drugs has been intensely investigated. Modern radiotherapy, aided by improved imaging and treatment delivery technology, is capable of targeting tumors more precisely, while sparing surrounding critical structures. Clinical trials with camptothecin derivatives and radiotherapy have been conducted in lung cancers. Combined modality therapy with TOP1 drugs and radiotherapy offers a new frontier for lung cancer therapy. We review the present state of TOP1-targeted chemotherapy and modern radiotherapy for lung cancer.

Abstract
The prognosis of patients with CNS involvement of solid tumors is poor. In these patients, systemic chemotherapy has a theoretical advantage of concurrent treatment of systemic disease and reduced risk of neurotoxicity. Here, we report on the efficacy and toxicity of topotecan/ifosfamide (TOPO/IFO) combination chemotherapy in patients treated for CNS involvement of different solid malignancies. Fourteen patients with CNS manifestations (seven with brain metastases, two meningeal carcinomatosis, and five both) of solid tumors (seven with breast cancer, six lung cancer, and one unknown primary cancer) received TOPO/IFO treatment. Eleven patients each were pretreated with 1-6 systemic therapy regimens and whole-brain irradiation. Patients received a total of 34 (median 2) TOPO/IFO cycles. TOPO dosage was 3.6 mg/m(2) (1.2 mg/m(2), days 1-3) and IFO dosage 3,000 mg/m(2) (1,500 mg/m(2), days 1-2) per cycle. Of 12 patients with brain metastases, one patient had partial remission, three stable disease, two progressed, and six had no radiologic CNS response evaluation. Response of meningeal carcinomatosis was found in two and progressive disease in two (three patients not evaluated). Neurologic improvement or stabilization was observed in six of twelve evaluable patients. No systemic tumor response was seen in seven evaluated patients. Grade 3/4 toxicities in eleven evaluable patients were leukopenia (n = 9), infection (n = 6), and thrombopenia (n = 5). Median time to treatment failure was 43 days and median overall survival 107 days. Symptom control was frequently achieved with TOPO/IFO systemic chemotherapy despite a low objective response rate. The feasibility of this treatment is impaired by severe hematotoxicity.

Abstract
Each year approximately 170,000 patients are diagnosed with brain metastasis in the United States, making this the most common intracranial tumor in adults. Historically, treatment strategies focused on the use of whole brain radiation therapy (WBRT) for palliation, yielding a median survival time of only 3 to 6 months. The possible effect of WBRT on cognitive function has generated much concern and debate regarding the use of this modality. Thus, the use of WBRT alone, or in conjunction with other treatment modalities should take into account both risks and benefits, to ensure the best patient outcome with regard to disease state and functional status. The advent of technologies permitting local dose-escalation have clearly increased local control rates, and in select patients, even survival, thereby, further intensifying the debate regarding the use of WBRT. Here, we review the use of WBRT, radiosurgery, and resection for the treatment of brain metastases. Further, we will review the use of radiation sensitizers and blood-brain barrier penetrating cytotoxics such as temozolomide. Finally, we will discuss current treatment strategies for possibly maintaining and improving cognitive function for these patients.

Abstract
BACKGROUND Combination chemotherapy has been the mainstay of treatment for extensive stage small celI lung cancer (SCLC) over the last 30 years even though it only gives a short prolongation in median survival time. The main goal for these patients should be palliation with the aim of improving their quality of life. OBJECTIVES To evaluate the effectiveness of chemotherapy in extensive SCLC compared with best supportive care (BSC) or placebo treatment. SEARCH STRATEGY MEDLINE (1966 to July 2008), EMBASE (1974 to week 31, 2008), and the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3, 2008). Experts in the field were contacted. SELECTION CRITERIA Randomised controlled trials in which any chemotherapy treatment was compared with placebo or BSC in patients with extensive SCLC, as first or second therapy at relapse. DATA COLLECTION AND ANALYSIS Two authors independently extracted data and assessed study quality. We resolved disagreements by discussion. Additional information was obtained from one study author. MAIN RESULTS Two studies were included for first-line chemotherapy. A total of 65 patients were randomised to receive either placebo or ifosfamide. Ifosfamide gave an extra mean survival of 78.5 days compared with placebo. Partial tumour response was greater with the active treatment. Toxicity was only seen in the chemotherapy group.Two studies were included for second-line chemotherapy at relapse. A total of 531 patients were randomised to receive either methotrexate-doxorubicin or symptomatic treatment, or to receive oral topotecan versus BSC. The methotrexate-doxorubicin treatment gave a median survival of 63 days longer than in the symptomatic treatment group, and 21 days longer for patients allocated to receive four or eight cycles of first-line chemotherapy, respectively.Treatment with topotecan gave a median survival of 84 days longer than in the BSC group (log-rank P = 0.01). The adjusted hazard ratio for overall survival was 0.61 (95% CI, 0.43 to 0.87). Partial or complete response in the methotrexate-doxorubicin group was 22.3%. Five patients (7%, 95% CI, 2.33 to 15.67) showed a partial response with topotecan. Toxicity was worst in the chemotherapy group. Quality of life was better in the topotecan group. AUTHORS' CONCLUSIONS Chemotherapeutic treatment prolongs survival in comparison with placebo in patients with advanced SCLC. Nevertheless, the impact of first-line chemotherapy on quality of life and in patients with poor prognosis is unknown. Well-designed, controlled trials are needed to further evaluate the risks and benefits of different chemotherapeutic schedules in patients with advanced SCLC.

Abstract
BACKGROUND Ovarian cancer is the fourth cause of death from gynaecological cancer and cervical cancer is the first in women <45 years old in developing countries. The aim of this article is to review the role of topotecan (Hycamtin), a semi-synthetic alkaloid derivative of camptothecin, in ovarian and cervical cancer in monotherapy and in combination. METHODS This article reviews the mechanism of action, pharmacokinetics, toxicity and efficacy of topotecan. The paper also reports the principal phases II and III studies of topotecan in advanced or recurrent ovarian and cervical cancer. RESULTS Topotecan (Hycamtin), currently indicated for the treatment of relapsed ovarian cancer, has demonstrated activity both in platinum-sensitive and in platinum-resistant disease. The combination cisplatin-topotecan for the treatment of advanced and recurrent cervical cancer has demonstrated a clinical benefit in terms of response rate, overall survival and progression free survival. Haematological toxicity of topotecan also is easy to manage and not cumulative, especially with the weekly scheduled recently introduced in clinical practice. CONCLUSION Topotecan (Hycamtin) will continue to play a role in the treatment of advanced ovarian and cervical cancer, in monotherapy or in combination with other cytotoxic agents.

Abstract
The multimodality management of brain metastases has undergone significant refinement in the last decade. Although brain metastases remain a significant source of morbidity and mortality for many cancer patients, aggresive management has led to pronounced gains in neurological functioning, disease free survival and overall survival compared to standard treatment regimens consisting of only whole brain radiation therapy. Representative studies reviewing the role of aggressive management approaches including surgical resection with or without whole brain radiation therapy or non-surgical approaches employing stereotactic radiosurgery alone or in combination with whole brain radiation therapy are highlighted. Additionally, the emerging role of systemic agents showing distinct clinical activity in patients with brain metastases are also discussed. As we continue to gain advances in systemic therapies for metastatic disease, local control of brain metastases in these patients is likely to become more critical in improving survival and quality of life, thereby calling for a more aggressive multi-modal approach to this population of patients.

Abstract
AIM The aim of this study was to investigate the effect of topotecan (TPT) on cancer cell migration. METHODS Growth inhibition of TPT was analyzed by MTT assay, and cancer cell migration was measured by transwell double chamber assay. To verify the effect of TPT on the chemokine receptors CXCR4 and CCR7, quantitative PCR, semi-quantitative PCR and Western blot analysis were performed. The secretion of MMP-2 and MMP-9 was detected by enzyme-linked immunosorbent assay (ELISA) and gelatin zymography. To evaluate possible contributions of CCR7 to MMP secretion, the overexpression vectors pcDNA3.1(+)-CCR7 and CCR7 siRNA were transiently transfected into MDA-MB-435 cells. RESULTS TPT inhibited cancer cell migration in a dose-dependent manner. Additionally, TPT significantly decreased the expression of CCR7 in both MDA-MB-435 and MDA-MB-231 cells and moderately reduced the expression of CXCR4 in MDA-MB-435 cells. The secretion of MMPs (MMP-2, MMP-9) was also inhibited by TPT. Overexpression of CCR7 increased the secretion of MMP-2/9 and cancer cell migration, whereas knockdown of CCR7 reduced active MMP-2/9 production and migration of MDA-MB-435 cells. CONCLUSION TPT inhibited cancer cell migration by down-regulation of CCR7 and MMPs (MMP-2 and MMP-9).

Abstract
A 46-year-old woman with IgA-lambda myeloma in partial remission, after a tandem autologous hematopoietic stem cells transplantation, complained of progressive lower back pain associated with paraplegia and neurological bladder 6 months after the second transplant. A lumbar puncture revealed atypical malignant plasma cells in the cerebral spinal fluid associated with multiple foci of altered signal intensity of brain and spinal cord demonstrated by magnetic resonance. Considering the lack of efficacious chemotherapies for neurological myeloma, an experimental systemic treatment with topotecan, temozolamide, and dexamethasone associated with concurrent radiotherapy of brain and spinal cord was initiated. During this treatment, the patient rapidly improved with disappearance of back pain, paresthesia, and urinary incontinence lasting 5 months, before dying of progressive disease. The proposed systemic chemotherapy associated with concurrent radiotherapy may have an antitumor activity against MM with CNS involvement.

Abstract
Brain metastases represent an important cause of morbidity in patients with lung cancer and are associated with a mean survival of less than 6 months. Thus, new regimens improving the outcome of these patients are urgently needed. On the basis of promising data raised in a phase I/II trial, we initiated an open, randomised, prospective, multicentric phase III trial, comparing whole brain radiation therapy (WBRT; 20 × 2 Gy) alone with WBRT+topotecan (RCT; 0.4 mg m−2 day−1 × 20). A total of 320 patients with CNS-metastases due to SCLC or NSCLC were projected. The primary end point was overall survival, whereas second end points were local response and progression-free survival. However, until the cutoff date of study completion (i.e., a study duration of 34 months), only a total of 96 (RCT:47, WBRT:49) patients had been recruited, and so an analysis was performed at that time point. Although the numbers of grade 3/4 non-haematological toxicities (besides alopecia 115 (RCT/WBRT: 55 out of 60) were evenly distributed, the 25 haematological events occurred mainly in the combined treatment arm (24 out of 1). Local response, evaluated 2 weeks after treatment, was assessable in 44 (RCT/WBRT: 23 out of 21) patients, showing CR in eight (3 out of 5), PR in 17 (11 out of 6), SD in 14 (8 out of 6) and PD in five (1 out of 4) patients (all differences n.s.). Neither OAS (RCT/WBRT: median (days)): 87 out of 95, range 3–752/4–433; HR 1.32; 95% CI (0.83; 2.10)) nor PFS (median (days)): 71 out of 66, range, 3–399/4–228; HR 1.28, 95% CI (0.73; 2.43) differed significantly. On the basis of these results and the slow recruitment, a continuation of the study did not seem reasonable. The available data show no significant advantage for concurrent radiochemotherapy for patients with lung cancer; however, the recruited number of patients is too low to exhibit a small advantage of combined treatment.

Abstract
PURPOSE Brain metastasis occurs commonly in patients with small-cell lung cancer (SCLC). Herein, we report the efficacy of irinotecan and carboplatin in the treatment of brain metastases from SCLC. In addition, we review the existing data on chemotherapy for brain metastases in SCLC. PATIENTS AND METHODS Eighty patients with metastatic or relapsed SCLC were enrolled in a phase II trial of irinotecan and carboplatin. Patients naive to chemotherapy were treated with irinotecan 200 mg/m2 and carboplatin AUC of 5, and patients previously treated with chemotherapy received irinotecan 150 mg/m2 and carboplatin AUC of 5, every 21 days for 6 cycles. RESULTS Among the 80 patients, 15 (19%) presented with brain metastases. An analysis of 14 assessable patients with brain metastases revealed an overall response rate of 65% after 2 cycles of chemotherapy and a median survival of 6 months (range, 1-24 months). Upon review of the literature, 8 studies were identified as having > 10 patients who received chemotherapy for brain metastases from SCLC. Based on these studies, the response rate of brain metastases from SCLC to a variety of chemotherapy and median survival of patients ranged from 22% to 85% and 3 months to 9 months, respectively. CONCLUSION Chemotherapy, including the regimen of irinotecan and carboplatin, is an effective treatment for SCLC brain metastases.

Abstract
PURPOSE The brain is a pharmacologic sanctuary site, due to the presence of the blood-brain barrier (BBB). Whereas the effect of P-glycoprotein (P-gp) at the BBB is well established, the role of breast cancer resistance protein (BCRP) that is also expressed at the BBB is not. EXPERIMENTAL DESIGN We have studied the effect of BCRP by administering topotecan to wild-type (WT), single Mdr1a/b(-/-) and Bcrp1(-/-), and compound Mdr1a/b(-/-)Bcrp1(-/-) knockout mice. Drug levels in plasma and tissues were determined by high-performance liquid chromatography. RESULTS The area under the plasma and tissue concentration-time curve (AUC) of topotecan in brains of Mdr1a/b(-/-) and Bcrp1(-/-) mice was only 1.5-fold higher compared with WT mice, but in Mdr1a/b(-/-)Bcrp1(-/-) mice, where both transporters are absent, the AUC increased by 12-fold. The AUC in plasma was approximately 0.75-, 2.4-, and 3.7-fold higher in Mdr1a/b(-/-), Bcrp1(-/-), and Mdr1a/b(-/-)Bcrp1(-/-) mice, respectively, resulting in 2.0-fold (P < 0.01), 0.65-fold (P, not significant), and 3.2-fold (P < 0.01), respectively, higher brain-to-plasma AUC ratios. Results using Mrp4(-/-) mice showed that this transporter had no effect on the brain penetration of topotecan. The P-gp/BCRP inhibitor elacridar fully inhibited P-gp-mediated transport of topotecan, whereas inhibition of Bcrp1-mediated transport by elacridar was minimal. CONCLUSIONS Our results using Mdr1a/b(-/-)Bcrp1(-/-) mice clearly show the effect of Bcrp1 at the BBB and also show how two drug transporters act in concert to limit the brain penetration of topotecan. We expect that this finding will also apply to other drugs that are substrates of both P-gp and BCRP. Consequently, to improve the brain penetration of such compounds for targeting intracranial malignancies in patients, it will be essential to use potent inhibitors of both drug transporters.

Abstract
Topotecan is a semisynthetic derivative of camptothecin that specifically targets topoisomerase I. It has well-established antineoplastic properties and has been successfully combined with other antineoplastic agents with activity dependent on DNA disruption, such as cisplatin and etoposide. Topotecan is indicated for the treatment of small cell lung cancer (SCLC) sensitive disease after failure of first-line chemotherapy and metastatic ovarian carcinoma after failure of initial or subsequent chemotherapy. Since the approval of topotecan for the second-line treatment of SCLC, studies have been conducted in the first-line setting. Recent studies demonstrate the utility of i.v. topotecan in combination with cisplatin for untreated SCLC. Further, an oral formulation of topotecan is currently under investigation and may provide added convenience for patients. Oral topotecan has been studied in the first- and second-line settings for both SCLC and non-small cell lung cancer (NSCLC). Three recent phase III trials have demonstrated the activity of oral topotecan. In the first study of chemotherapy-naïve patients with extensive-disease SCLC, oral topotecan plus cisplatin provided efficacy and safety similar to those of etoposide plus cisplatin. In a second study of patients with relapsed SCLC, treatment with oral topotecan showed a statistically significant and clinically meaningful longer overall survival time and improvement in dyspnea and quality of life compared with best supportive care alone in all prognostic groups. Finally, in previously treated patients with NSCLC, single-agent oral topotecan was shown to be noninferior in 1-year survival rate relative to the current standard of i.v. docetaxel. In future studies, oral topotecan will represent a good candidate for combination therapy with other i.v. or oral chemotherapy agents, monoclonal antibodies, and small molecule tyrosine kinase inhibitors.
