Abstract
Elevated expression of the ATP-binding cassette (ABC) drug transporter ABCG2 in cancer cells contributes to the development of the multidrug resistance phenotype in patients with advanced non-small-cell lung cancer (NSCLC). Due to the lack of U.S. Food and Drug Administration (FDA)-approved synthetic inhibitors of ABCG2, significant efforts have been invested in discovering bioactive compounds of plant origin that are capable of reversing ABCG2-mediated multidrug resistance in cancer cells. Sophoraflavanone G (SFG), a phytoncide isolated from the plant species Sophora flavescens, is known to possess a wide spectrum of pharmacological activities, including antibacterial, anti-inflammatory, antimalarial, and antiproliferative effects. In the present study, the chemosensitizing effect of SFG in ABCG2-overexpressing NSCLC cells was investigated. Experimental results demonstrate that at subtoxic concentrations SFG significantly reversed ABCG2-mediated multidrug resistance in a concentration-dependent manner. Additional biochemical data and in silico docking analysis of SFG to the inward-open conformation of human ABCG2 indicate that SFG inhibited the drug transport function of ABCG2 by interacting with residues within the transmembrane substrate-binding pocket of ABCG2. Collectively, these findings provide evidence that SFG has the potential to be further tested as an effective inhibitor of ABCG2 to improve the efficacy of therapeutic drugs in patients with advanced NSCLC.

[PMID: 29052349 PMCID: PMC5754284 DOI: 10.1111/1759-7714.12535] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2017] [Revised: 09/09/2017] [Accepted: 09/09/2017] [Indexed: 11/29/2022] Open
Abstract
Background The objective of this study was to evaluate the effects of gene polymorphisms, including UGT1A1*7, *27, and *29, on the safety of irinotecan therapy. Methods The eligibility criteria were: lung cancer patients scheduled to undergo irinotecan therapy, aged ≥ 20 years, with a performance status of 0–2. Thirty‐one patients were enrolled and their blood was collected and used to examine the frequency of UGT1A1*6, *7, *27, *28, and *29 polymorphisms and the concentrations of irinotecan, SN‐38, and SN‐38G after irinotecan therapy. Results The patients’ characteristics were as follows: male/female 25/6, median age 71 years (range 55–84), stage IIB/IIIA/IIIB/IV 2/6/11/12, and adenocarcinoma/squamous cell carcinoma/small cell carcinoma/other 14/10/3/4, respectively. The −/−, *6/−, *7/−, *27/−, *28/−, and *29/− UGT1A1 gene polymorphisms were observed in 10 (32%), 10 (32%), 2 (6%), 2 (6%), 7 (23%), and 0 (0%) cases, respectively. The UGT1A1*27 polymorphism occurred separately from the UGT1A1*28 polymorphism. The lowest leukocyte counts of the patients with the UGT1A1*27 and UGT1A1*6 gene polymorphisms were lower than those observed in the wild‐type patients. SN‐38 tended to remain in the blood for a prolonged period after the infusion of irinotecan in patients with UGT1A1*27 or UGT1A1*28 polymorphisms. No severe myelotoxicity was seen in the patients with UGT1A1*7. Conclusion UGT1A1*27 can occur separately from UGT1A1*28 and is related to leukopenia during irinotecan treatment. UGT1A1*7 is less relevant to irinotecan‐induced toxicities, and UGT1A1*29 seems to have little clinical impact.

Abstract
Purpose. The primary objective of this article is to discuss the pharmacology, pharmacokinetics, clinical use, and adverse effects of the approved topoisomer ase I inhibitors. This is the second in a series of two articles and will focus on irinotecan. Data Sources. We reviewed the literature through a MEDLINE search of English language arti cles from 1985 through 1998. Relevant articles cited in the titles obtained from the MEDLINE search were also used. The following terms were used for purpose of conducting the MEDLINE search: topoisomerase inhibitors, irinotecan, topoisomerase I, camptosar, and CPT-11. Data Extraction. We have reviewed the current literature to discuss the pharmacology, pharmacokinet ics, clinical use, toxicity, drug interactions, indications, formulation, dosage and administration, and pharmaceu tical issues surrounding the use of irinotecan. Data Synthesis. The topoisomerase I inhibitors are new antineoplastic agents with a unique mechanism of action. Promising areas of application include colo rectal cancer, non-small-cell lung cancer, small-cell lung cancer, cervical cancer, and lymphomas. Clinical trials detailing the activity of topoisomerase I inhibitors in these areas are presented.

Abstract
PURPOSE To determine the maximum tolerated dose of amrubicin (AMR) with a fixed dose of irinotecan (CPT-11). METHODS Patients having pathologically proven small cell lung cancer (SCLC) relapsed after one or two chemotherapies, and Eastern Cooperative Oncology Group performance status of 0 to 2 were eligible for the study. CPT-11 was delivered as 50 mg/m2 on days 1 and 8, every 21 days. AMR was delivered on day 1. Doses of AMR were level 1: 80 mg/m2, level 2: 90 mg/m2, and level 3: 100 mg/m2. Dose elevation was determined using the modified continuous reassessment method. Tolerability was assessed after the first cycle. Another two cycles were conducted when disease progression or unacceptable toxicities were not observed. RESULTS Eighteen patients (mean age: 66.3 years) were enrolled. A total of 40 courses were conducted. Grade 3/4 toxicities of the first cycle were leukocytopenia: 11 (61%, grade 3/4: 8/3); neutropenia: 15 (83%, grade 3/4: 6/9); and thrombocytopenia: three (17%, grade 3/4: 2/1). Other grade 3 toxicities observed were febrile neutropenia, one; infection, three; diarrhea, one; and dyspnea, one. Dose-limiting toxicity was observed in two of six patients at level 2 (neutropenia and febrile neutropenia) and in one of six at level 3 (thrombocytopenia and infection). The maximum tolerated dose was level 3, and so, the recommended dose for phase II trials was judged to be 90 mg/m2. Objective response was obtained in four of eight patients who were able to evaluate responses. Median survival time was 13 months, with 68% at 1-year survival rate. CONCLUSIONS This combination was well tolerated and showed encouraging activities in SCLC. Randomized phase II trials are being planned in chemonaive SCLC.

Abstract
INTRODUCTION To determine whether irinotecan maintenance therapy in extensive disease-small cell lung cancer can improve survival of patients who responded to irinotecan plus cisplatin (IP) induction therapy. METHODS A total of 120 chemo-naive patients with adequate organ functions and Eastern Cooperative Oncology Group performance status of 0 to 2 were enrolled from March 2003 through April 2006. After IP induction therapy, with either schedule A (I: 60 mg/m intravenously (IV) on days 1, 8, and 15; P: 30 mg/m IV on days 1 and 8, every 4 weeks for six cycles) or schedule B (I: 60 mg/m and P: 30 mg/m IV on days 1, and 8, every 3 weeks for eight cycles), responding patients were randomized to either maintenance with irinotecan 100 mg/m IV on days 1, 8, and 15, every 4 weeks up to six cycles, or observation. RESULTS Overall, 100 (83%) of 120 patients achieved objective tumor responses (12 complete responses, 88 partial responses) after IP induction therapy. Of those patients who remained in remission upon completion of planned cycles of induction therapy, 45 were randomized to maintenance (n = 21) or observation (n = 24). Median progression-free survival (PFS) and overall survival (OS) for all patients were 7.2 and 14.0 months, respectively. For the maintenance arm, median PFS and OS were 12.0 and 17.6 months, respectively. For the observation arm, median PFS and OS were 9.9 and 20.5 months, respectively, which was not significantly different from the maintenance arm. CONCLUSIONS IP chemotherapy is very useful for the treatment of small cell lung cancer. However, maintenance irinotecan therapy did not seem to further affect the clinical outcome of patients who had responded to IP induction therapy.

Abstract
OBJECTIVE To clarify the association between pre-treatment total bilirubin (PTB) level and severe toxicity in patients receiving cisplatin and irinotecan. METHODS We analyzed retrospectively the relationships of grade 4 neutropenia or grade 3-4 diarrhea and clinical variables including PTB and pre-treatment neutrophil counts (PNC) using a logistic regression model. RESULTS One hundred and twenty-seven patients (93 men, 34 women; median age: 61 years; range: 24-74 years) received cisplatin (60 or 80 mg/m2) on day 1 and irinotecan (60 mg/m2) on days 1 and 8 every 3 weeks or on days 1, 8 and 15 every 4 weeks. Grade 4 neutropenia occurred in 29 patients (23%) and grade 3-4 diarrhea occurred in 13 patients (10%). Grade 4 neutropenia was associated with a higher PTB level (odds ratio: 4.9; 95% confidence interval: 1.4-17.7), a higher cisplatin dose (2.8, 1.0-7.8) and a lower PNC (1.5, 1.0-2.3). Grade 3-4 diarrhea was associated with liver metastasis (11.2, 2.2-57.4), a higher cisplatin dose (5.0, 1.2-21.3) and a lower PNC (2.0, 1.1-3.6). CONCLUSIONS PTB level was associated with the severity of neutropenia caused by cisplatin and irinotecan.

Abstract
Object
There is currently no effective chemotherapy for meningiomas. Although most meningiomas are treated surgically, atypical or malignant meningiomas and surgically inaccessible meningiomas may not be removed completely. The authors have investigated the effects of the topoisomerase I inhibitor irinotecan (CPT-11) on primary meningioma cultures and a malignant meningioma cell line in vitro and in vivo.
Methods
The effects of irinotecan on cellular proliferation in primary meningioma cultures and the IOMM-Lee malignant meningioma cell line were measured by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium bromide assay and flow cytometry. Apoptosis following drug treatment was evaluated by the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling and the DNA laddering assays. The effects of irinotecan in vivo on a meningioma model were determined with a subcutaneous murine tumor model using the IOMM-Lee cell line.
Irinotecan induced a dose-dependent antiproliferative effect with subsequent apoptosis in the primary meningioma cultures (at doses up to 100 μM) as well as in the IOMM-Lee human malignant meningioma cell line (at doses up to 20 μM) irinotecan. In the animal model, irinotecan treatment led to a statistically significant decrease in tumor growth that was accompanied by a decrease in Bcl-2 and survivin levels and an increase in apoptotic cell death.
Conclusions
Irinotecan demonstrated growth-inhibitory effects in meningiomas both in vitro and in vivo. Irinotecan was much more effective against the malignant meningioma cell line than against primary meningioma cultures. Therefore, this drug may have an important therapeutic role in the treatment of atypical or malignant meningiomas and should be evaluated further for this purpose.

Abstract
OBJECTIVES The combination of irinotecan and cisplatin given every 4 weeks is one of the standard treatments for advanced nonsmall-cell lung cancer (NSCLC) in Japan. The purpose of this study is to evaluate the efficacy, safety and dose-intensity as a measure of the feasibility of 3-week scheduling of irinotecan and cisplatin in patients with advanced NSCLC in phase II study. METHODS Previously untreated patients with stage IIIB and IV NSCLC were treated intravenously with irinotecan (60 mg/m2) on days 1 and 8 and cisplatin (60 mg/m2) on day 1 of a 3-week cycle. RESULTS Of the 28 patients enrolled, 27 were evaluable for response and toxicity. The response rate was 30% (95% confidence interval, 14-50%). The median duration of response was 16 weeks (range, 10-26 weeks). The median survival time for all patients was 52 weeks and the 1-year and 2-year survival rates were 48% and 29%, respectively. The dose-intensity of irinotecan was 34 mg/m2/wk (range, 19-40). The major toxicities observed were neutropenia (grade 3, 30%; 4, 30%), leukopenia (grade 3, 30%), and diarrhea (grade 3, 22%). Other toxicities were generally mild. CONCLUSIONS Three-week scheduling of irinotecan and cisplatin is effective and feasible in advanced NSCLC.

Abstract
PURPOSE The use of in vitro drug cytotoxicity assays for the assessment of drug-drug interactions that lead to synergy may not take into account the many cellular determinants responsible for combination effects. Administration of the anticancer drug CPT-11, for example, is associated with rapid conversion of drug from its active lactone form to the inactive carboxylate form. Thus it is difficult to model, in vitro, the behavior of this drug when used as a single agent and when used in a combination setting, this factor may contribute to the interactions measured. Therefore, the objective of this study was to examine the influence of CPT-11 lactone ratio on the cellular accumulation of CPT-11 when used as a single agent and under conditions where it is used in combination with cisplatin. METHODS A fixed ratio experimental design was used and drug ratios of CPT-11 and cisplatin were judged to be antagonistic, additive, or synergistic to the non-small cell lung cancer cell line, H460, on the basis of the median effect analysis methodology of Chou and Talalay. The influence of extracellular pH on CPT-11 accumulation was evaluated at pH 7.4 and pH 6.6 when the drug was added immediately to the cells or first pre-equilibrated at the indicated pH. These studies were completed in the presence and absence of cisplatin. RESULTS When CPT-11 was added as a single agent to cells in pH = 7.4 media, the drug underwent hydrolysis to the carboxylate form; however, there was a rapid accumulation of the CPT-11 lactone form which peaked at 3,800 pmol/mg protein by 30 min and drops to 570 pmol/mg protein by 24 h. In pH = 6.6 media, accumulation of CPT-11 lactone was substantially lower over a 60 min timecourse; however, the cellular uptake measured at 24 h was comparable to that observed when the drug was added into pH 7.4 media. When evaluating CPT-11 lactone accumulation in a combination setting with cisplatin no significant difference in either CPT-11 lactone accumulation or cisplatin accumulation was observed, suggesting that drug interactions that led to synergy were mechanistically based. Results are presented which suggest that when cisplatin and CPT-11 are used in combination, there was a significant prolongation of platinum association with DNA compared to results obtained when cisplatin was used alone. CONCLUSION These results suggest that the CPT-11 lactone to carboxylate ratio does not influence the accumulation of the active CPT-11 lactone form in H460 cells and that CPT-11 does not influence cisplatin uptake when used in combination. It is argued, therefore, that the improved cytotoxicity between CPT-11 and cisplatin, as determined using cell-based assay, has the potential to be preserved in vivo assuming the optimal drug-drug ratio and concentration can be effectively delivered to the tumor.

Abstract
BACKGROUND A Phase II study was conducted to evaluate the efficacy and toxicity of an irinotecan plus capecitabine combination, a new nonplatinum regimen, in chemonaive patients with advanced nonsmall cell lung carcinoma (NSCLC). METHODS Between July 2003 and April 2004, 53 patients with a histologically confirmed diagnosis of NSCLC were enrolled. All but 5 patients were male, 52 (98%) had an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1, 39 (74%) had AJCC Stage IV disease, and the median age was 61 years. Treatment consisted of intravenous irinotecan at a dose of 90 mg/m(2) on Days 1 and 8 and oral capecitabine at a dose of 1000 mg/m(2) twice daily on Days 1-14 of each 21-day cycle, given up to 12 cycles. RESULTS Of 53 patients enrolled, 22 achieved objective tumor responses (all partial responses) for an overall response rate of 41.5% (95% confidence interval [95% CI], 28.2-54.8%). After a median follow-up of 17.4 months, the median survival was 14.6 months with a 1-year survival rate of 60.1% (95% CI, 46.9-73.4%) and a median progression-free survival of 5.1 months. Treatment was very well tolerated, with only 10% of patients experiencing NCI-CTC Grade 3 or 4 toxicities. The most common toxicities were hand-foot syndrome and diarrhea. In multiple logistic regression analysis for overall response, only the stage predicted for significantly better response (P = 0.04). Squamous cell carcinoma was marginally predictive for better response (P = 0.08). CONCLUSIONS The irinotecan plus capecitabine regimen demonstrated an antitumor activity that is favorably comparable with other commonly used cisplatin-based regimens. Given the mild toxicity profile and favorable survival outcome, this nonplatinum regimen warrants further evaluation in a randomized trial.

The combination of cisplatin (CDDP) and 5-fluorouracil (5-FU) has been reported to show marked therapeutic effects on experimental tumors and human malignancies, such as head and neck cancer. In these clinical studies, CDDP was administered on day 1 and followed by a 5-d continuous infusion of 5-FU. However, it was repeatedly shown that the sequence of 5-FU followed by CDDP is more active and less toxic in tumor-bearing animals. Thus, the optimal administration schedule of CDDP and 5-FU against L1210 murine leukemia was examined and compared with that of the combination of 5-FU and carboplatin (JM-8). The combinations of 5-FU (days 1 to 5) and CDDP, given either on day 1 or on day 5, showed a similar level of antitumor activity and toxicity. On the other hand, the combinations of 5-FU (days 1 to 5) and JM-8 given on day 5 showed significantly higher antitumor activity and rather less toxicity, as compared with the combinations on the reverse sequence. Thus, the treatment sequence of platinum compounds followed by a 5-d continuous infusion of 5-FU in many clinical studies appears to be extremely favorable to CDDP than JM-8. In addition, pathological examinations of died mice showed that accumulation of ascites and pleural effusion was inhibited most effectively by JM-8, given alone or in combination with 5-FU. These results strongly suggest that the combination of 5-FU followed by JM-8 will be expected to show more excellent antitumor activity against human malignancies, and may be especially useful in patients who are unable to tolerate CDDP-related toxicity.

Abstract
PURPOSE OF REVIEW This review examines the evidence for the causality and pathogenesis of lung cancer associated with interstitial lung disease. RECENT FINDINGS Although cigarette smoking is the leading cause of lung cancer, several other conditions either predispose to lung cancer or increase the risk of lung cancer in smokers. The evidence supports an increased risk of lung cancer due to specific fibrotic and inflammatory lung diseases (termed interstitial lung diseases), including idiopathic pulmonary fibrosis, systemic sclerosis, and certain pneumoconioses. The potential pathogenetic mechanisms indicate that recurrent injury and inflammation result in genetic alterations that predispose to lung cancer. SUMMARY Idiopathic pulmonary fibrosis, systemic sclerosis, and certain pneumoconioses are associated with an independent increased risk of lung cancer; however, a unifying pathogenetic mechanism to explain the causality of this association has not been described. In addition, the inconsistently reported lung cancer frequencies call attention to the need for prospective studies of good quality.

Abstract
The aim of this study was to compare the irinotecan/cisplatin regimen with cisplatin as second-line chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC) pretreated with a taxane/gemcitabine regimen. Patients (n = 147) with stage IV NSCLC pretreated with a taxane/gemcitabine regimen were randomly assigned to receive either irinotecan (110 mg m(-2), day 1 and 100 mg m(-2), day 8) and cisplatin (80 mg m(-2), day 8) (IC; n = 74) or CDDP (80 mg m(-2), day 1) (C; n = 73) every 3 weeks. Patients treated with IC and C had a median survival of 7.8 and 8.8 months, respectively (P = 0.933). The 1-year survival rate was 34.3% for IC-treated patients and 31.7% for C-treated patients. Cox's regression analysis revealed that response to treatment (hazard ratio (HR) = 2.787; 95% confidence interval (CI): 1.1578-4.922) and performance status (HR = 1.865; 95% CI: 1.199-2.872) was independent prognostic factors for survival. Overall response rate was 22.5% (95% CI: 12.8-32.2%) for IC-treated patients and 7.0% (95% CI: 1.15-13.6%) for C-treated patients (P = 0.012); tumour growth control (partial remission (PR) + stable disease (SD)) was observed in 26 (38%) IC and 25 (36%) C patients (P = 0.878). There was no difference in terms of quality of life between the two chemotherapy arms. The incidence of febrile neutropenia, grade 3 and 4 neutropenia and grade 3 and 4 diarrhoea was significantly higher in the IC- than the C-treated patients. Other toxicities were mild. There were no treatment-related deaths in either arm. The IC regimen did not confer a survival benefit compared with C as second-line treatment of patients with advanced NSCLC pretreated with a taxane/gemcitabine regimen, despite its better efficacy in terms of response rate.

Abstract
Irinotecan, a new topoisomerase I inhibitor, has significant activity in the treatment of untreated and previously treated patients with small-cell lung cancer (SCLC). In combination with cisplatin, a Japanese randomized trial showed a statistically significant survival advantage over cisplatin/etoposide in chemotherapy- naive patients with extensive-stage disease. This represents the first major advance in the treatment of extensive-stage SCLC in 20 years. Randomized trials in the United States are underway to confirm these impressive results. Meanwhile, trials incorporating irinotecan and cisplatin into treatment regimens for limited-stage disease are being conducted. Furthermore, irinotecan-containing regimens with other agents such as carboplatin, etoposide, and paclitaxel in first- or second-line therapies for SCLC are being evaluated. Preliminary results are encouraging. This article will highlight the exciting results achieved with irinotecan in SCLC and discuss its promising future in this disease.

Abstract
More than one third of all non-small-cell lung cancer (NSCLC) patients present with advanced stage IV disease with metastases or with stage IIIB disease with a malignant pleural or pericardial effusion. The prognosis for these patients remains poor despite some improvement in survival produced by 2-drug chemotherapy combinations. With the best 2-drug combinations, the expected median survival is 8-9 months and > 80% of patients die within 2 years of diagnosis. The overall response rate to the best combination is < 40% and the complete response rate is only 1%. Clearly, superior therapies are needed. The topoisomerase I inhibitors have been developed because the topoisomerase I enzyme plays a critical role in the DNA repair process. Irinotecan is a topoisomerase I inhibitor developed during the 1990s. It was initially approved in the United States for the treatment of colorectal cancer. In early trials, considerable activity was seen in both small-cell lung cancer and NSCLC. These observations led to combination studies with cisplatin. Cisplatin-based therapy had become a standard approach in both stage IV disease and in combination with chest radiotherapy in stage IIIB disease because metaanalyses of randomized trials showed that cisplatin-based therapy significantly improved survival. Randomized trials also showed that cisplatin-based therapy improved symptoms in the majority of patients and improved quality of life. In early combination studies, the irinotecan/cisplatin combination produced responses in an average of 40% of patients and produced median survival times that averaged about 10 months. In randomized trials comparing irinotecan/cisplatin to vindesine/cisplatin, the irinotecan/cisplatin combination was slightly better than irinotecan alone and vindesine/cisplatin. These encouraging results led to ongoing randomized trials comparing the 2-drug combination of irinotecan/cisplatin to other 2-drug combinations. Irinotecan has also been combined safely and effectively with carboplatin. The 2-drug combination of irinotecan/carboplatin produced results similar to those achieved with irinotecan/cisplatin. Irinotecan has also been incorporated into 3-drug combinations such as irinotecan/carboplatin/paclitaxel with encouraging results. A randomized trial comparing docetaxel/irinotecan to docetaxel/cisplatin showed similar results. Randomized trials comparing the 3-drug combination to a 2-drug combination are in progress. The irinotecan/cisplatin combination has considerable activity in the second-line setting. Randomized trials comparing this combination to docetaxel are needed. Irinotecan is an active agent in the first- and second- line therapy of NSCLC.

Abstract
To determine a standard combination chemotherapy for patients with advanced non-small-cell lung cancer (NSCLC), we conducted a phase III trial of irinotecan (CPT-11) to test the hypotheses that CPT-11+cisplatin is superior to cisplatin+vindesine and that CPT-11 monotherapy is not inferior to cisplatin+vindesine. A total of 398 patients with previously untreated NSCLC were randomised to receive cisplatin+CPT-11 (CPT-P), cisplatin+vindesine (VDS-P) or CPT-11 alone (CPT). In the CPT-P arm, CPT-11 60 mg m(-2) was administered on days 1, 8 and 15, and cisplatin 80 mg m(-2) was administered on day 1. In the VDS-P arm, cisplatin 80 mg m(-2) was administered on day 1, and vindesine 3 mg m(-2) was administered on days 1, 8 and 15. In the CPT arm, CPT-11 100 mg m(-2) was administered on days 1, 8 and 15. The median survival time was 50.0 weeks for patients on CPT-P, 45.6 weeks for those on VDS-P and 46.0 weeks for those on CPT (P=0.115, CPT-P vs VDS-P; P=0.089, CPT vs VDS-P), and the hazard ratio was 0.85 (95% confidence interval (CI): 0.65-1.11) for CPT-P vs VDS-P and 0.83 (0.64-1.09) for CPT vs VDS-P. The response rate was 43.7% for patients on CPT-P, 31.7% for those on VDS-P and 20.5% for those on CPT. Major adverse reactions were grade 4 neutropenia observed in 37, 54 and 8% of the patients on CPT-P, VDS-P and CPT, respectively; and grades 3 and 4 diarrhoea observed in 12, 3 and 15% of the patients, respectively. CPT-P therapy produces comparable survival to VDS-P in patients with advanced NSCLC. CPT-11 monotherapy is not inferior to VDS-P in terms of survival. The CPT-11-containing regimen is one of the most efficacious and well tolerated in the treatment of advanced NSCLC.

Abstract
Irinotecan possesses significant single-agent activity in non-small-cell lung cancer (NSCLC) and is active in combination with either cisplatin or carboplatin. Two phase III trials completed in Japan have suggested that the combination of irinotecan/cisplatin yields superior survival rates in stage IV NSCLC patients compared to vindesine/cisplatin. The principal toxicities of the irinotecan/cisplatin regimen are neutropenia and diarrhea. This regimen is currently being tested in Japan against regimens commonly used in the United States, such as cisplatin/gemcitabine, cisplatin/vinorelbine, and carboplatin/paclitaxel. These studies include evaluation of monthly as well as weekly schedules of cisplatin in combination with irinotecan as well as a triplet regimen of irinotecan/carboplatin/paclitaxel. Ongoing trials are evaluating these regimens as well as irinotecan/carboplatin and several nonplatinum-based irinotecan-containing doublets in both the first- and second-line treatment of advanced NSCLC. Several ongoing trials are attempting to integrate irinotecan with thoracic radiation therapy in stage III NSCLC. These trials are using irinotecan-containing regimens as induction and concurrent therapy with thoracic radiation therapy. Irinotecan is also being evaluated in the preoperative setting in early-stage resectable NSCLC. Many of these trials are also incorporating celecoxib, a potent inhibitor of the cyclooxygenase-2 pathway, in combination with irinotecan-containing regimens in both advanced as well as early-stage NSCLC. Future trials should focus on the integration of the new targeted agents in combination with irinotecan-containing regimens in all stages of NSCLC.

Abstract
BACKGROUND This Phase II multicenter, open-label, single-arm study evaluated the efficacy and safety of a three-drug combination of irinotecan (CPT-11), paclitaxel, and carboplatin in advanced nonsmall cell lung carcinoma (NSCLC). METHODS Patients received repeated 21-day cycles at starting doses of paclitaxel 175 mg/m(2) administered over 3 hours, followed by carboplatin AUC of 5 over 30 minutes and CPT-11 at a starting dose level of 100 mg/m(2) over 90 minutes, all given on the first day of each cycle. Patients were evaluated for objective tumor response, time to tumor progression (TTP), survival, and safety. RESULTS Forty patients were enrolled. Baseline patient characteristics included: median age 58 years (range, 32-79); 23 males and 17 females; performance status of 0 (21 patients), 1 (18 patients), or 2 (1 patient); and Stage IIIB (10 patients) and Stage IV (30 patients) disease. A median of six cycles (range, one to eight) were administered. Grade 3-4 toxicities observed in >/= 10% of the patients included neutropenia (78%), asthenia (20%), diarrhea (20%), nausea (18%), vomiting (13%), anemia (10%), and dyspnea (10%). Febrile neutropenia occurred in eight patients (20%), with one death due to neutropenic sepsis. Twelve of 38 evaluable patients had confirmed tumor responses (32%), while 21 (55%) had stable disease (including 12 patients [32%] with minor responses). Only 13% had disease progression at their initial tumor assessment. The median TTP and survival were 5.3 months (range, 0.03-6.2 months) and 12.5 months (range 0.3-28.6+ months), respectively. The one and two year survival probabilities were 0.50 (95% confidence interval [CI], 0.28-0.73) and 0.21 (95% CI, 0.0-0.67), respectively. CONCLUSIONS The combination of CPT-11, paclitaxel, and carboplatin can be safely administered and is active in the treatment of advanced NSCLC. Based on the favorable survival outcome, this regimen is undergoing evaluation in prospective randomized trials.

Abstract
Combinations of topoisomerase I (topo I) poisons and platinum derivatives have synergistic antitumoral effects. However, their clinical development is limited by supra-additive haematological toxicity. The aim of this study was to determine whether sustained doses of topotecan and oxaliplatin could be achieved using a synergistic sequence. 34 advanced cancer patients and 186 cycles were evaluable for toxicity over five dosing levels. Oxaliplatin at 85-110 mg/m(2) was given on day 1, followed by topotecan 0.5-1.25 mg/m(2)/day x 5 from day 1 to 5, every 3 weeks. Plasma pharmacokinetics (PK) of total and ultrafiltrable platinum, total and lactone forms of topotecan were determined in the first cycle. The dose-limiting toxicity (DT) was identified as grade 4 thrombocytopenia. The occurrence of grade 4 thrombocytopenia did not correlate with topotecan PK, but it did with the patient's characteristics. Severe thrombocytopenia was seen in 1/8 of patients without clinical or biological evidence of malnutrition, with a creatinine clearance higher than 1 ml/s, and no more than two previous chemotherapy regimens, while it was seen in 8/10 patients with one of these characteristics (P<0.004). In conclusion, the recommended doses of oxaliplatin 110 mg/m(2) and topotecan 1 mg/m(2)/day, every 3 weeks can be administered to patients with a favourable general status and pretreatment characteristics and a phase II study is worthwhile in ovarian cancer patients.

Abstract
PURPOSE We conducted a phase I trial of escalating doses of topotecan (TOPO) in association with a fixed systemic exposure of carboplatin (CARBO) with or without granulocyte colony-stimulating factor (G-CSF) in children. PATIENTS AND METHODS Two separate cohorts of patients (pts) with solid tumors were studied: (A) pts with refractory or recurrent disease and (B) pts with no prior myelosuppressive therapy or newly diagnosed tumors for which there was no standard chemotherapy. CARBO was given on day 1 at an area under the curve of 6.5, followed by TOPO as a continuous infusion for 3 days; the starting dose of TOPO was 0.50 mg/m(2)/d. Cycles were repeated every 21 days. G-CSF was given at a dose of 5 microg/kg/d starting on day 4. RESULTS Forty-eight of 51 pts were assessable for toxicity. In group A, dose-limiting myelosuppression persisted despite de-escalation of TOPO to 0.3 mg/m(2)/d and use of G-CSF. In group B, the maximum-tolerated dose of TOPO was 0.5 mg/m(2)/d for 3 days, and 0.6 mg/m(2)/d for 3 days with G-CSF. No significant nonhematologic toxicities were observed. Among 46 pts assessable for response, one had complete response, five had partial response, and 18 had stable disease. CONCLUSION Although this combination possesses antineoplastic activity in pediatric solid tumors, hematologic toxicity precluded any meaningful TOPO dose escalation. The addition of G-CSF did not alter this. The potential for preservation of activity and diminution of toxicity with alternative sequences and schedules of administration (topoisomerase followed by alkylating or platinating agents) should be evaluated.

Abstract
In the last years, the main topoisomerase I inhibitors (TP1-I) (i.e. topotecan and irinotecan) have been used in combination chemotherapy in non-small cell lung cancer. Several drugs (also alternative to cisplatin) have been used in combination with TP1-I, but to date the higher remission rate obtained with combinations is not translated into a more prolonged survival in comparison with TP1-I given alone. On the other hand, the toxicity of TP1-I combinations is greater than those of TP1-I used alone. The superior efficacy of combinations versus TP1-I used alone remains an open question. Furthermore, the best schedule for TP1-I has not been completely elucidated. Randomised studies are few (only two phase III trials) and only controlled studies will be able to clarify the best TP1-I combination regimen.

Abstract
Irinotecan (CPT-11) and cisplatin (P) are both active agents against non-small cell lung cancer (NSCLC), and their combination has shown in vitro an additive or synergistic effect. We conducted a phase II study to determine the toxicity and efficacy of their combination as salvage treatment in patients with advanced NSCLC progressing after a docetaxel-based front line regimen. Forty-four patients with histologically confirmed NSCLC were enrolled. The patients' median age was 60.5 years; 39 patients (87%) were male; 38 (86%) had stage IV disease; and 32 (73%) had a performance status (WHO) 0-1. CPT-11 was administered as a 60 min i.v. infusion at a dose of 100 mg/m(2) on day 1 and 110 mg/m(2) on day 8; P was administered at a dose of 80 mg/m(2) on day 8 after CPT-11 administration. Treatment was repeated every 3 weeks. A total of 159 chemotherapy cycles was administered. In an intention-to-treat analysis, nine patients (22; 95% CI: 9.28-34.62%) achieved a partial response (PR), 8 (20%) had stable disease (SD), and 24 (58%) progressive disease (PD). The median duration of response was 4 months, the median time-to-progression (TTP) 8 months, and the median survival for the entire group 8 months. Grade 3-4 neutropenia was observed in 20 (46%) patients and in four cases this was febrile, requiring patient's hospitalisation. Grade 3-4 thrombocytopenia occurred in four (9%) patients. Grade 3-4 diarrhoea was seen in 12 (27%) patients and three of them required hospitalisation. Grade 2-3 neurotoxicity was observed in two (4%) patients and grade 2-3 fatigue in 14 (32%). Other toxicity was mild and no treatment-related death was reported. The combination of CPT-11 and P is a safe, well-tolerated, and active regimen for the treatment of patients with advanced NSCLC previously treated with a docetaxel-based front-line regimen.

Abstract
Cisplatin (DDP) is one of the key drugs used to treat patients with ovarian cancer, although resistance to DDP can occur. Paclitaxel and SN-38 (an active metabolite of irinotecan (CPT-11)) are two drugs that are effective in patients with DDP-resistant ovarian cancer. To study how these drugs may overcome the intrinsic and / or acquired resistance of cancer cells to DDP, we investigated the effect of a combination of DDP with paclitaxel and a combination of DDP with SN-38 on three ovarian cancer cell lines, RTSG (intrinsically resistant cell line), KF (DDP-sensitive cell line), and KFra (acquired resistant cell line obtained from KF). We found that these combinations showed additive to synergistic antitumor activity. A time-dependent platinum (Pt) accumulation was observed in the DDP-sensitive KF cell line, while a decrease occurred in the KFra cell line. Little accumulation was observed in RTSG. Intracellular Pt accumulation was increased in all three cell lines by exposure to paclitaxel or SN-38. Ouabain, a Na(+),K(+)-ATPase inhibitor, decreased Pt accumulation in KF and KFra cell lines and inhibited the paclitaxel- and SN-38-induced increases in Pt accumulation in these cell lines. When we assessed the mRNA levels of the multidrug resistance-associated protein (MRP), which may be an efflux pump for DDP, the combination of paclitaxel or SN-38 with DDP down-regulated these levels, which are up-regulated by DDP alone. These results suggest that paclitaxel and SN-38 overcome DDP resistance of ovarian cell lines by controlling intracellular accumulation of DDP via both the influx and efflux systems.

Abstract
BACKGROUND In 1999, the World Health Organization categorized large cell neuroendocrine carcinoma, large cell carcinoma with neuroendocrine differentiation, and large cell carcinoma with neuroendocrine morphology as a variant of large cell carcinoma. Patients with large cell carcinoma with neuroendocrine features have poor prognoses, comparable to those for small cell lung carcinoma. Small cell lung carcinoma is sensitive to chemotherapy; however, it is still unclear whether large cell carcinoma with neuroendocrine features is responsive to adjuvant chemotherapy. METHODS The authors analyzed 73 patients with large cell carcinoma with neuroendocrine features who underwent resection of the tumor and studied the effect of adjuvant chemotherapy for large cell carcinoma with neuroendocrine features. RESULTS In patients with Stage I disease, the overall survival for patients with adjuvant chemotherapy based on cisplatin, carboplatin, or cyclophosphamide, which were used as standard chemotherapy for small cell lung carcinoma, were significantly higher than the overall survival for patients without adjuvant chemotherapy. In patients with Stage II, III, and IV disease, there was no significant difference between patients with adjuvant chemotherapy and without adjuvant chemotherapy. CONCLUSIONS Adjuvant chemotherapy based on cisplatin, carboplatin, or cyclophosphamide prolongs survival of patients with large cell carcinoma with neuroendocrine features in early stage.

Abstract
A phase II study of fractionated administration of irinotecan (CPT-11) and cisplatin (CDDP) in patients with non-small-cell lung cancer (NSCLC) was conducted. Between January 1996 and January 1998, 44 previously untreated patients with stage IIIB or IV NSCLC were enrolled. CDDP at a dose of 60 mg x m(-2) was given first and followed by CPT-11 at a dose of 50 mg x m(-2). Both drugs were given by 1-hour infusion on days 1 and 8, and repeated every 4 weeks up to 4 cycles. 42 patients were evaluated for response and 44 for survival and toxicity. 20 patients (48%: 95% confidence interval 32-63%) achieved an objective response. The median duration of responses was 8 months, and the median survival time and the 1-year survival rate were 12.5 months and 56.8%, respectively. Major toxicities were neutropenia and diarrhoea. Grade 3 or 4 neutropenia occurred in 70.5% of the patients and one patient died of sepsis. Grade 3 or 4 diarrhoea was experienced in 25.0%, but manageable by conventional therapy. In conclusion, fractionated administration of CPT-11 and CDDP was highly effective for advanced NSCLC with manageable toxicities.

Abstract
The objectives of this phase I/II trial were to determine the maximum tolerated dose, toxicities, and the dose suitable for phase II/III trials of irinotecan (CPT-11) combined with paclitaxel and carboplatin in patients with advanced non small-cell lung cancer (NSCLC). Seventy-three patients with stage IIIB/IV NSCLC were enrolled in this multicenter, phase I/II study. The initial regimen was paclitaxel 225 mg/m2 over 3 hours, followed by carboplatin at an area under the curve (AUC) of 6 over 30 minutes on day 1 and CPT-11 starting at 40 mg/m2 over 90 minutes on days 1 and 8, every 3 weeks. Dose-limiting toxicity occurred in three of the original seven patients. The regimen was amended with doses reduced to paclitaxel 175 mg/m2 over 3 hours, carboplatin AUC = 5, and CPT-11 at 40 mg/m2, all on day 1 every 3 weeks. Dose escalation of CPT-11 proceeded to 80 mg/m2 and 125 mg/m2 before dose-limiting toxicities were experienced. Subsequent patients received an intermediate CPT-11 dose of 100 mg/m2. Doses suitable for phase II study were determined to be paclitaxel 175 mg/m2 over 3 hours, carboplatin AUC = 5, and CPT-11 100 mg/m2. The pri-mary first-cycle dose-limiting toxicities were neutropenia and diarrhea. The most common grade 3/4 toxicity observed during all cycles was neutropenia. On the phase I portion of the study, objective tumor response was observed in 39% (12 of 31, 95% confidence interval: 22%-58%). The median time to tumor progression was 6.8 months, median survival was 11.0 months, and 1-year survival probability was 0.46. These data were confirmed in the phase II portion with a 30% objective response rate, median time to progression of 5.6 months, median survival of 12.5 months, and a 1-year survival probability of 0.50. In conclusion, CPT-11 100 mg/m2, paclitaxel 175 mg/m2, and carboplatin AUC = 5 given every 3 weeks can be safely administered in patients with advanced NSCLC. Neutropenia and diarrhea are the dose-limiting toxicities. The combination shows appreciable activity, and survival data are favorable, warranting further study of this regimen. A review of other irinotecan-containing triplet combinations is presented.

Abstract
Lung cancer is the leading cause of cancer death in the United States and in the world. In the United States, lung cancer ranks first in cancer deaths for both men and women. The 5-year survival rate is only 15%, but this has improved considerably from the 5% rate in the early 1960s. For many years, the standard therapy for patients with advanced, stage IIIB and IV non small-cell lung cancer (NSCLC) was best supportive care, which consisted of palliative radiotherapy, pain management, and other symptom management. The median survival for these patients was only 4 months, and more than 85% died in the first year after diagnosis. Cisplatin was the first drug that was shown to prolong the survival of patients with advanced lung cancer. Meta-analyses of randomized trials showed that cisplatin reduced the hazard rate of death by 26%, increased median survival from 4 to 6 months, and increased 1-year survival from 15% to 25%. Cisplatin-based therapy also relieved symptoms in the majority of patients and improved the quality of life as assessed by patients themselves. Still, further advances are desperately needed, as three fourths of the cisplatin-treated patients die within a year of diagnosis. Topoisomerase I inhibitors are a new class of chemotherapeutic agents introduced into lung cancer therapy during the 1990s. Irinotecan (CPT-11) was shown to be active in patients with both small-cell and non small-cell lung cancers. The activity of irinotecan in advanced NSCLC made it logical to combine irinotecan with the two platinums, cisplatin and carboplatin. The combination of irinotecan with cisplatin produced response rates of about 40% in phase II trials conducted in previously un-treated patients with advanced NSCLC. The median survival in these studies ranged from 6-8 months, and the 1-year survival rates ranged from 40%-60%. Because carboplatin is more convenient and better tolerated than cisplatin, a number of more recent phase II trials have evaluated the combination of irinotecan and carboplatin in patients with advanced NSCLC. These trials produced results similar to those achieved with irinotecan/cisplatin and with other two-drug combinations such as paclitaxel/carboplatin and gemcitabine/ cisplatin. The excellent activity of the two-drug combination or irinotecan and a platinum led to trials of three-drug combinations, such as irinotecan/carboplatin/paclitaxel. Preliminary results from these studies showed excellent survival, although the toxicity required some dosage reductions. Randomized trials will be necessary to determine whether such three-drug combinations will be preferred over standard two-drug combinations.

Abstract
PURPOSE To determine the maximum-tolerated dose, toxicities, and dose suitable for phase II/III trials of irinotecan (CPT-11) combined with paclitaxel and carboplatin in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Patients with stage IIIB/IV NSCLC were enrolled to this multicenter, phase I study. The initial regimen was paclitaxel 225 mg/m(2)/3 h, followed by carboplatin area under the curve (AUC) 6 over 30 minutes on day 1, and CPT-11 starting at 40 mg/m(2) over 90 minutes, days 1 and 8, every 3 weeks. Dose-limiting toxicity occurred in three of seven patients. The regimen was amended, with doses reduced to paclitaxel 175 mg/m(2)/3 h, carboplatin AUC 5 and CPT-11 at 40 mg/m(2), all on day 1 every 3 weeks. Dose escalation of CPT-11 proceeded to 80 mg/m(2) then 125 mg/m(2) before dose-limiting toxicities were experienced. Subsequent patients received an intermediate CPT-11 dose of 100 mg/m(2). RESULTS Thirty-three patients were enrolled; 32 patients were assessable for safety, and 31 were assessable for tumor response. The primary first-cycle dose-limiting toxicities were neutropenia and diarrhea. The most common grade 3/4 toxicity observed during all cycles was neutropenia (16 patients [50%], with six [19%] developing neutropenic fever). Objective tumor response was observed in 39% (12/31, 95% confidence interval, 22% to 58%). The median time to tumor progression was 6.8 months, median survival 11.0 months, and 1-year survival probability 0.46. CONCLUSION CPT-11 100 mg/m(2), paclitaxel 175 mg/m(2), and carboplatin AUC 5 given every 3 weeks can be safely administered in patients with advanced NSCLC. Neutropenia and diarrhea are the dose-limiting toxicities. The combination shows appreciable activity, and survival data are favorable.

Abstract
PURPOSE A phase I study was conducted to determine the maximum-tolerated dose (MTD) and the dose-limiting toxicities (DLTs) of a CPT-11 plus cisplatin combination as salvage treatment in patients with advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS Twenty-two patients with histologically confirmed NSCLC, who had failed taxotere-based front-line chemotherapy, were enrolled. The patients' median age was 61 years, 19 (86%) were male, and 17 (77%) had a performance status (World Health Organization (WHO)) 0-1. CPT-11 was administered as a 60-min i.v. infusion at a fixed dose of 100 mg/m2 on day 1 and at escalating doses on day 8, starting from 100 mg/m2 with increments of 10 mg/m2; cisplatin was administered at a fixed dose of 80 mg/m2 on day 8, 2 h after CPT-11 administration. Treatment was repeated every 3 weeks. RESULTS At the dose of CPT-11 120 mg/m2, three out of four enrolled patients presented DLTs (grade 4 neutropenia, febrile neutropenia and delayed diarrhea); the addition of G-CSF at this level did not permit further dose-escalation. Grade 3/4 neutropenia was observed in 12 (18%) cycles, febrile neutropenia in four (6%), and grade 3/4 thrombocytopenia in four (6%). Grade 3/4 diarrhea was seen in six (29%) patients, and grade 2/3 nausea and vomiting in 12 (57%). Neurotoxicity grade 2 was observed in six (29%) patients and grade 3 in one (5%). Other toxicities were mild. The MTD was CPT-11 100 mg/m2 on day 1 and 110 mg/m2 on day 8 in combination with CDDP 80 mg/m2 on day 8. Among 12 patients evaluable for response, partial response was achieved in two (16.7%) patients and stable disease in five (41.7%). CONCLUSION The combination of CPT-11 and cisplatin has substantial but manageable toxicity and marginal activity as salvage treatment of patients with NSCLC who have failed taxotere-based front-line chemotherapy: further investigation is warranted to define its precise role in the second-line setting.

Abstract
A phase I study was conducted in patients with stage IIIB or IV non-small cell lung cancer to determine the maximum tolerated dose (MTD) of irinotecan combined with a fixed schedule of docetaxel and carboplatin with recombinant human granulocyte colony stimulating factor (rhG-CSF) (nartograstim) support. Docetaxel was given at 60 mg/m2 on day 1 with carboplatin. The dose of carboplatin was calculated using the Calvert formula to achieve an estimated AUC of 5.0 mg/ml x min. Irinotecan was administered at a starting dose of 40 mg/m2 on day 1 and increased in increments of 10 mg/m2. rhG-CSF was given at 1 microg/kg on days 5-15. Cycles were repeated every 3 weeks. Between February 1998 and March 1999, 22 patients were enrolled in this phase I study. Five patients were chemotherapy naive. The MTD of irinotecan was 60 mg/m2. Diarrhea was considered to be the dose-limiting toxicity. The irinotecan dose intensity of 16.7 mg/m2/week was low compared with other irinotecan-containing regimens. The overall response rate was 38.1% and median survival was 278 days. Irinotecan 50 mg/m2 in combination with 60 mg/m2 docetaxel and carboplatin on day 1 with rhG-CSF support is recommended for phase II study. The response rate and survival data in this phase I study are encouraging.

Abstract
BACKGROUND To determine the dose-limiting toxicity of CPT-11 in combination with oxaliplatin, and the maximal tolerated dose (MTD) and the recommended dose (RD) of CPT-11 using an every two weeks schedule. PATIENTS AND METHODS The study was designed to evaluate escalated doses of CPT-11 starting at 100 mg/m2 with a fixed clinically-relevant dose of 85 mg/m2 oxaliplatin given every two weeks. RESULTS Twenty-three patients and 186 cycles were evaluable for toxicity (median per patient: 7, range: 1-13). Grade 3 oxaliplatin-induced neurotoxicity was cumulative and limiting in 39% (9 of 23) of patients. The MTD of CPT-11 was 200 mg/m2, with incomplete neutrophil recovery at day 15 as limiting toxicity. At the RD (175 mg/m2 of CPT-11): no grade 4 neutropenia was seen in the two first cycles; 30% of patients experienced grade 3-4 diarrhea. Febrile neutropenia (3.2% of all cycles) was 3-fold more frequent in performance status (PS) 2 than in PS0-1 patients. Among eleven colorectal cancer (CRC) patients, three complete and four partial responses were documented, including in three 5-fluorouracil (5-FU) refractory patients. CONCLUSION To combine CPT-11 175 mg/m2 and oxaliplatin 85 mg/m2 every two weeks is feasible in an outpatient setting, and very active in 5-FU resistant CRC patients. A dose of 150 mg/m2 CPT-11 is recommended in PS2 patients.

Abstract
The camptothecin analogs topotecan and irinotecan have shown to be among the most effective anticancer agents and, as S-phase specific agents, their antitumor effect is maximized when they are administered in protracted schedules. The documented activity as single agents in many adult and pediatric malignancies has been followed by their use in combination with other anticancer agents. These studies have shown promising results, and have placed topotecan and irinotecan in the first line treatment for some malignancies. However, studies to better determine the optimal schedules and sequence of combinations are needed.

Abstract
Treatment of patients with advanced non-small cell lung cancer (NSCLC) remains a vexing problem and long-term survival beyond 5 years is extremely rare. Five new agents, paclitaxel, docetaxel, vinorelbine, gemcitabine and irinotecan, have been introduced for the treatment of NSCLC and investigated extensively both preclinically and clinically. Monotherapy with one of these agents has produced survival benefits over the best supportive care in Phase III studies. Combination chemotherapy with a new agent and platinum produced a higher response rate than conventional cisplatin-based chemotherapy and improved survival was observed in some randomised trials. There was little difference in efficacy and toxicity between the chemotherapeutic regimens with a new agent and a platinum in Phase III trials, suggesting the clinical utility of these regimens is similar. Many trials have focused on regimens containing two new agents, with or without platinum. Preliminary results of Phase III trials of three drug combinations versus two drug combinations suggested the former to be more promising, in terms of response rates and survival. Whether the era of platinum-based chemotherapy in the treatment of NSCLC should continue or not must be determined by Phase III trials, evaluating the use of a platinum agent with one of the new agent combinations. These aggressive chemotherapeutic combinations will hopefully improve survival and quality of life for patients with advanced NSCLC.

Abstract
The effects of methanol extract of Rubus crategifolius roots and its solvent fractions were investigated on the proliferation of MCF-7 human breast carcinoma cells. The methanol extract inhibited the proliferation of MCF-7 cells in a concentration dependent manner. Moreover, their methanol soluble (W-M) fraction had the greatest inhibitory effect on the growth of MCF-7 cells. To evaluate whether the W-M fraction affects on the cell cycle of MCF-7 cells, cells treated with this fraction were analyzed with flow cytometry. The W-M fraction increased G0/G1 phase after 24 h-treatment and induced apoptosis after 48 h-treatment. The hallmark of apoptosis, DNA fragmentation, also appeared by W-M fraction after 48 h-treatment. Furthermore, the methanol extract and its W-M fraction inhibited the activity of the topoisomerase I enzyme in the relaxation assay. From these results, their W-M fraction as well as methanol extract of R. crategifolius roots are necessary for further studies as a potent inhibitor of the growth of cancer cells.

Abstract
BACKGROUND A phase II study was conducted in order to determine the toxicity and efficacy of the combination of CPT-11 and cisplatin, as salvage treatment in patients with advanced non-small-cell lung cancer (NSCLC), progressing after a docetaxel-based front-line regimen. PATIENTS AND METHODS Thirty-one patients (median age 61 years) with NSCLC, were enrolled. Twenty-six (84%) patients were male, twenty-five (81%) had disease stage IV, and twenty-eight (90%) had a performance status (WHO) 0-1. CPT-11 was administered as a 60-minute i.v. infusion at the dose of 100 mg/m2 on day 1 and 110 mg/m2 on day 8; cisplatin was administered at the dose of 80 mg/m2 on day 8, after CPT-11 administration. Treatment was repeated every three weeks. RESULTS A total of 110 chemotherapy cycles were administered. In an intention-to-treat analysis 7 patients (23%; 95%) Introduction confidence interval (95% CI): 8%-37%) achieved a partial response, 6 (19%) had stable disease, and 18 (58%) progressive disease. Three of responders had failed a previous docetaxel-carboplatin combination. The median duration of response was 3 months, the median TTP 8 months and the median survival for the entire group 8 months. Grade 3-4 neutropenia was observed in 16 (52%) patients and in two cases this was febrile. Grade 3 and 4 thrombocytopenia occurred in two (7%) patients, respectively. Grade 3 and 4 diarrhea was seen in 10 (33%) patients, grade 2-3 neurotoxicity in 2 (6%), and fatigue grade 2-3 in 12 (39%). Other toxicities were mild. CONCLUSIONS The combination of CPT-11 and cisplatin has manageable toxicity and interesting activity as salvage treatment of patients with advanced NSCLC, previously treated with a docetaxel-based front-line regimen.

Abstract
The renewed interest in topoisomerase 1 inhibitors, based on new insights on the mechanism of action and the development of semi-synthetic derivates of camptothecin with a more favourable toxicity profile, has led to extensive preclinical and clinical research. Significant levels of anti-tumor activity in human tumor xenografts were seen especially with prolonged duration of exposure. Since oral drug delivery is a more convenient method for prolonged drug administration, and preferred by patients, further development of oral formulations seems attractive. Common concerns in the development of oral formulations are their sometimes low oral bioavailability and the frequently large intra- and interpatient variation in systemic exposure. Efforts to improve absorption and minimize intestinal metabolism/efflux of the oral chemotherapeutic agent using new formulas might lead to better bioavailability. Pharmacokinetic and pharmacodynamic evaluations have enabled guidance in recommendations of schedules. Given the interpatient variation in exposure it is interesting to note that flat dosing of topotecan resulted in the same systemic exposure compared with the more complex dosing per body surface area. In order to diminish the interpatient variation in exposure to 9-AC a limited sampling model for oral 9-AC was developed, enabling prediction of the systemic exposure for 9-AC and optimizing treatment for any given patient. Drug sequencing plays a key role in the combination topotecan/cisplatin and might be important for combination with other classes of drugs. Therefore, forthcoming phase 1 trials on combination therapy with oral topoisomerase 1 inhibitors should include studies on sequence dependence and pharmacokinetic analyses to evaluate any mutual interaction.

Abstract
Over the past 5 to 7 years, new and promising systemic agents have entered the therapeutic armamentarium in the treatment of advanced non-small-cell lung cancer. In particular, the taxanes, irinotecan, vinorelbine, and gemcitabine, have each been shown to perturb the natural history of this disease. In combination with cisplatin, these agents have yielded improvements in response rates and in survival, compared with either cisplatin alone or with older platinum combinations, with consistent 1-year survival rates of 30% to 40% or more and response rates exceeding 25%. Other factors may also be responsible for improved survival rates, including patient selection, improved supportive care, and more extensive screening procedures, such as CT and positron emission tomography, which have resulted in stage migration. Future directions will focus on the role of nonplatinum combinations, particularly in the elderly and in patients with compromised performance status; salvage therapy in patients with intact performance status; quality of life and quality adjusted survival; and the role of new biologic agents, which alter the tumor milieu and may be readily integrated into standard cytotoxic regimens. Except for unfit or unwilling patients, there is no room for therapeutic nihilism.

Abstract
PURPOSE To assess the feasibility, pharmacokinetic interaction, and possible sequence-dependent effects of the irinotecan/cisplatin combination given every 3 weeks, and to assess the influence of additional granulocyte colony-stimulating factor (G-CSF) on the hematologic toxicity. PATIENTS AND METHODS Patients who had received no more than one prior combination chemotherapy regimen or two single-agent regimens were entered. Treatment consisted of a 90-minute irinotecan infusion followed by a 3-hour cisplatin infusion on day 1, with cycles repeated once every 3 weeks. After the maximum-tolerated dose was determined, the sequence of administration was reversed. In a separate cohort of six patients, we assessed the effect of G-CSF on the experienced hematologic toxicity and dose-intensity. Irinotecan doses ranged from 175 to 300 mg/m(2) and cisplatin doses ranged from 60 to 80 mg/m(2). RESULTS Fifty-two patients entered the study; one was not eligible, and two were not assessable for response. Twenty-five patients were pretreated, and 26 were not. Fifty-one patients received a total of 223 courses. The dose-limiting toxicity was a combination of neutropenic fever, diarrhea, and fatigue at a dose level combining irinotecan 300 mg/m(2) with cisplatin 80 mg/m(2). Neutropenia was common (grades 3 to 4, 68%). Irinotecan pharmacokinetics were linear over the dose range studied. No sequence-dependent side effects were observed. Tumor responses included three complete responses and eight partial responses. CONCLUSION For phase II studies, we recommend irinotecan 260 mg/m(2) combined with cisplatin 80 mg/m(2) once every 3 weeks for chemotherapy-naive patients in good physical condition, and irinotecan 200 mg/m(2) combined with cisplatin 80 mg/m(2) for other patients.

Abstract
PURPOSE To investigate the pharmacokinetics and pharmacodynamics of irinotecan and cisplatin administered once every 3 weeks in a dose-escalating study in patients with solid tumors. PATIENTS AND METHODS Fifty-two cancer patients were treated with irinotecan administered as a 90-minute infusion at doses ranging from 175 to 300 mg/m(2) followed by cisplatin administered as a 3-hour intravenous infusion at doses ranging from 60 to 80 mg/m(2). After reaching the maximum-tolerated dose, the sequence of drug administration was revised. For pharmacokinetic analysis, serial plasma samples were obtained on days 1 through 3 of the first cycle. Forty-five patients were assessable for irinotecan pharmacokinetics, and 46 were assessable for cisplatin pharmacokinetics. RESULTS Irinotecan and cisplatin demonstrated linear pharmacokinetics comparable to that observed with single-agent administration, which suggests an absence of pharmacokinetic interaction. SN-38G constituted the major plasma metabolite of irinotecan, whereas 7-ethyl-10-[4-N-(1-piperidino)1-amino]-carbonyloxycamptothecine (NPC) was only a minor metabolite in plasma, possibly indicating a rapid conversion of NPC to SN-38. The terminal elimination phases of SN-38 and SN-38G were similar and relatively delayed when compared with the elimination of irinotecan. Maximal DNA adduct formation did not significantly differ from that observed with single-agent administration. The percentage decrease in WBC was significantly related to the areas under the plasma concentration-time curve (AUCs) of the lactone form of irinotecan (P =.0245) and SN-38 (P =. 0123). The severity of diarrhea was not significantly related to the AUCs of irinotecan and SN-38, nor to the systemic glucuronidation rate of SN-38. CONCLUSION There was no apparent pharmacokinetic interaction between irinotecan and cisplatin in this study. Reversion of the administration sequence of the drugs did not seem to have any influence on the pharmacokinetics. The incidence and severity of delayed-type diarrhea was not related to any of the studied parameters.
