Abstract
Non-small cell lung cancer (NSCLC) is the most frequent type of lung cancer accounting up to 80-85% of all lung cancer (LC) cases. Gemcitabine (Gem), a pyrimidine nucleoside antimetabolite, is widely used chemotherapy offering several months survival benefit in patients with NSCLC. The emergence of Gem resistance is a main clinical concern in cancer treatment and thus a continuous demand for development of new therapeutic strategies to improve its antitumor activity. Hence, we report an adjuvant therapeutic regimen based on natural compound, gambogic acid (GA) which has been shown to enhanced Gem induced inhibition of cancer cell growth, arrest cell cycle, and induce apoptosis by enhanced accumulation of Gem. The in vitro cell viability, clonogenicity, invasion, and migration assays demonstrated a significant higher therapeutic effect of Gem when it was combined with GA in A549 and H1299 cells. A better access of internalization of drug molecules achieved in rhodamine 123 assay when GA was used as adjuvant treatment. Further, GA and Gem combination significantly reduced tubular formation of HUVEC cells indicates lowering angiogenesis potential. Microarray and Western blot studies confirm that GA + Gem co-treatment strategy promotes cancer cell death by downregulating anti-apoptotic proteins, chemoresistance-associated proteins, and upregulation of apoptosis proteins. More importantly, a significant higher therapeutic benefit was noticed for GA and Gem combination in A549 xenograft mice model. Together, these results offer a rationale to evaluate the clinical translational possibility of GA as adjuvant therapy to overcome Gem resistance. This combination regimen can be a new therapeutic concept to eradicate this devastating disease.

Association between polymorphisms of ERCC1 and XPD and survival in non-small-cell lung cancer patients treated with cisplatin combination chemotherapy. Lung Cancer 2004; 44:311-6. [PMID: 15140544 DOI: 10.1016/j.lungcan.2003.11.019] [Citation(s) in RCA: 182] [Impact Index Per Article: 9.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2003] [Revised: 11/20/2003] [Accepted: 11/25/2003] [Indexed: 11/30/2022]
Abstract
ERCC1 (excision repair cross-complementation group 1) and XPD (ERCC2, excision repair cross-complementation group 2) as genes have been known to be belonged to the nucleotide excision repair pathway and therefore related to DNA repair. Polymorphisms in these genes have been rarely evaluated in terms of predicting cancer patient survival. We investigated whether these polymorphisms have an effect on response to chemotherapy and survival in 109 patients with non-small-cell lung cancer treated with cisplatin combination chemotherapy. Polymorphisms of ERCC1 Asn118Asn (C --> T), XPD Lys751Gln (A --> C) and Asp312Asn (G --> A) were evaluated using a SNaPshot kit. As for chemotherapy response, treatment response did not show statistically significant differences between the wild genotypes and the variant genotypes for the ERCC1 and XPD gene. The median survival time of all patients was 376 days (95% CI, 291-488). As for survival rate according to the polymorphism of codon 118 in ERCC1, median survival time in patients showing C/C genotype was 486 days (95% CI, 333-x), which was significantly different from the 281 days (95% CI, 214-376) of patients with the variant genotype (T/T or C/T) (P = 0.0058). Using the Cox-proportional hazards model, the polymorphism of codon 118 in ERCC1, response to chemotherapy, weight loss and performance status effected overall survival significantly (P = 0.0001, 0.0001, 0.0028 and 0.0184, respectively). However, polymorphisms of codons 751 and 312 in the XPD gene did not affect patient survival (P = 0.4711 and 0.4542, respectively). Therefore, we suggest that the C/C genotype in codon 118 of ERCC1 is a surrogate marker for predicting better survival in non-small-cell lung cancer patients treated with cisplatin combination chemotherapy.

Abstract
BACKGROUND AND AIMS Most patients with non-small cell lung cancer (NSCLC) cannot tolerate a cisplatin-based chemotherapy because of old age, general conditions, and/or multiorgan metastatic sites. Oxaliplatin is active in NSCLC, offers advantage in terms of toxicity, and shows synergism with gemcitabine. The aims of this phase II study were to evaluate the response rate and toxicity of the gemcitabine-oxaliplatin combination in patients with advanced NSCLC and poor prognosis. METHODS Patients were given a gemcitabine infusion (1000 mg/m(2) over 30 min on days 1 and 8) followed by oxaliplatin (65 mg/m(2) over 120 min on days 1 and 8) every 21 days for six cycles. RESULTS Thirty-two patients with poor-prognosis advanced NSCLC received 136 cycles. There were 25 males and seven females, and the median age was 65 years (range 29-76). Fifty-six percent of patients had adenocarcinoma, and 31% had squamous cell carcinoma. Sixty-six percent of patients had stage IV disease, and 34% had stage IIIB disease. Eastern cooperative oncology group (ECOG) performance status was 2-3 in 50%, 1 in 44%, and 0 in 6% of patients. Eight patients (25%) had been previously treated with cisplatin or carboplatin. All patients were symptomatic. Of the 32 patients who received study drug, five (16%) achieved partial response, six (19%) had minor response, three (9%) had stable disease, and 15 (47%) progressed. The median overall survival was 27 weeks. Thirty-one patients were evaluable for toxicity: seven patients (23%) had grade 3-4 thrombocytopenia with no bleeding; four patients (13%) had grade 3-4 neutropenia with no febrile neutropenia, and three patients (10%) had grade 3 anemia. Two patients (6%) had grade 3, and six patients (19%) had grade 1-2 neurotoxicity. CONCLUSION The combination of gemcitabine and oxaliplatin seems to be well tolerated and active in patients with poor prognosis advanced NSCLC and deserves further evaluation in phase II clinical trials.

Abstract
Cisplatin-based chemotherapy is being tried in the treatment of nonoperable cases of non-small-cell lung cancer (NSCLC). However, the prognosis is unfavorable and to improve survival, clinical studies using various combinations of a variety of drugs as well as experimental material are in progress. We compared the efficacy and toxicities of combination chemotherapy using different doses of vinorelbine and ifosfamide with a constant dose of cisplatin in this study. Patients diagnosed with inoperable stage III or IV NSCLC between June 1997 and December 1998 were included. Cisplatin was administered at a constant dose of 80 mg/m2 on day 5, whereas vinorelbine on days 1 and 5 and ifosfamide on day 5 were administered in one of two different doses. In arm A, vinorelbine 25 mg/m2 and ifosfamide 3.0 g/m2 were administered. In arm B, vinorelbine 20 mg/m2 and ifosfamide 2.5 g/m2 were administered. Also, we reviewed for phase II and III studies that test 1) cisplatin, 2) vinorelbine monotherapy, and 3) vinorelbine/cisplatin/ifosfamide combination chemotherapy for stage IIIb-IV non-SCLC. Summation dose intensity (SDI) was calculated in each published and current study. Twenty patients in arm A and 35 patients in arm B were available for evaluation. There was no difference in patient activity, pathologic diagnosis, and differentiation or stage between the two arms. The median number of cycles was four in both arms. The response rate was 50% in arm A and 30% in arm B. The median survival times for arm A and B were 40 and 42 weeks, respectively, whereas the SDI was 1.94 and 1.7, respectively. More than grade III leukopenia was observed in 28.9% in arm A, which is more frequent than the 17.2% in arm B. There was a significant correlation between the SDIs and response rates and median survival (r2 = 0.629, p = 0.001; r2 = 0.453, p = 0.001, respectively). Although the follow-up period is relatively short, the survival time was similar in both arms. Because a high response rate may not be followed by a high survival time in combination chemotherapy of NSCLC, further studies on the appropriate dose of individual agents with regard to the relationship between response rate, severity, and incidence of toxicities and survival rate should be carried out.

Abstract
Non-small cell lung cancer (NSCLC) accounts for about 80% of all primary lung cancers, and 60% of cases present as advanced stages IIIB and IV disease. Traditionally, treatment of stages IIIB and IV disease was only symptomatic (including radiotherapy) and supportive care, and cytotoxic chemotherapy was relatively ineffective. Our initial clinical trials, using MACC, FuAM, FAM, Hi-FAM and cisplatin-VP16, gave response rates of 5-20% and a stabilization rate of 7-25%, with no impact on median survival. Our most recent chemotherapy regimen MIP (mitomycin-C, ifosfamide and cisplatin) proved to be more effective with a 44% response rate and a 28% stabilzation rate, and produced a significantly longer median survival (32 weeks) than best supportive care alone (19.5 weeks, P< 0.05). The response rate further increased to 62.5% with dose intensification and GM-CSF support. Chemotherapy can now be recommended to motivated, well-informed patients with good performance status in institutions with experience in cancer chemotherapy on a protocol basis. The most recent addition of new effective cytotoxic agents such as paclitaxel, docetaxel, gemitabine and vinorelbine gave promising results in NSCLC, and optimal combinations and dose schedules are being defined by multicentred studies.

Abstract
The aim of this phase II study was to determine the antitumour activity and safety of trans-1-diaminocyclohexane-platinum (oxaliplatin) in previously untreated advanced non-small cell lung cancer (NSCLC) patients. 33 patients with unresectable and measurable NSCLC were entered into this phase II study between January 1992 and January 1994. Patients had either locoregional disease with performance status 2 (19 patients) or a stage IV disease (14 patients). Oxaliplatin (130 mg/m2) was given on an out-patient basis (2-h infusion, every 21 days) without hydration. Response was assessed after every two courses. One hundred courses were administered, with a mean of three courses per patient (range 1-12). All patients were evaluable for response; 1 had a complete response, and 4 a partial response (overall response rate 15%, 95% confidence interval 5.1-31.9%). The median response duration was 5.9 months. All cycles (n = 100) were evaluable for toxicity assessment. Transient reversible, cold-related finger dysesthesias occurred in 29 patients, but were mild, and disappeared in most cases within a few days. We observed brief episodes of pharyngolaryngeal discomfort (8 patients, 11 episodes) accompanied in 4 cases (3 patients), by transient episodes of inspiratory stridor, leading 2 patients to treatment withdrawal. We conclude that oxaliplatin has activity in poor-prognosis NSCLC and that this treatment is feasible in out-patients; the absence of renal and haematological toxicity makes this drug a good candidate for further evaluation in NSCLC.

Abstract
Chemotherapy has been shown to lengthen survival in patients with stage IIIA NSCLC when used pre-operatively (major response rates of 50% to 75%). Chemotherapy in combination with radiation for unresectable stage IIIA or IIIB disease has also improved survival rates. Major response rates of 10% to 30% are reported in cases of stage IV disease. Chemotherapy is now remarkably successful in achieving response in patients with limited SCLC, and 5-year survival rates as high as 10% to 15% are reported. Further increases in the 5-year survival rate will depend on improved chemotherapeutic treatment of nonsurgical disease. Research in the 1990s has presented a number of new chemotherapeutic agents with promising activity against this recalcitrant disease.

Abstract
Combination chemotherapy with anti-proliferative agents is often used in patients with advanced non-small cell lung cancer (NSCLC) in good performance status. The mitomycin C, vinblastine and cisplatin (MVP) regimen has been the Eastern Cooperative Oncology Group (ECOG) standard for several years because of high response rates in spite of significant toxicity. In a phase II study, we observed 55 consecutive patients treated with MVP chemotherapy using the same dosage, schedule, and precautions as used by the ECOG group. The dose intensity reached for each drug was 85% of the projected dose. Fifty-one patients were assessable for response and toxicity, while all subjects were evaluable for survival. There was no complete remissions, 8 partial (15%), 34 stable (66%) and 9 progressive (17%) in patients. The median survival rate was 34 weeks (95% confidence interval 28-37 weeks). There were no treatment-related deaths and no grade 4 toxicity. Alopecia and emesis were the most significant adverse effects. Haematological toxicity was minimal. Other side-effects, such as neuropathy and nephrotoxicity, were also rare. Hence, response rates and toxic complications were lower than previously reported. We conclude that the MVP regimen has to be re-evaluated.

Abstract
10-ethyl-10-deazaaminopterin (10-EDAM) is a rationally designed derivative of the antifolate, methotrexate (MTX). In a number of tumor models these design features have resulted in an improved spectrum of antiproliferative activity as compared with the parent compound. Using an MTT growth assay, we compared in vitro antiproliferative activity of 10-EDAM with MTX in eight lung cancer cell lines. Growth was inhibited in all lines tested by clinically achievable concentrations of 10-EDAM (0.1-1,000 nM). 10-EDAM was more cytotoxic than MTX at the same concentrations in all eight lung cancer cell lines. In an effort to enhance the antiproliferative effect, we evaluated the addition of dipyridamole (DPM), an inhibitor of nucleoside transport, to 10-EDAM (0.1-10 microns). DPM decreased the concentration of 10-EDAM required to cause 50% growth inhibition (IC50) in all eight cell lines tested. This suppression was statistically significant by 2-sided sign test (P = .0078). By contrast, the IC50 of MTX was decreased in only two of the eight cell lines when DPM was added (0.1-10 microM). In defined thymidine depleted media, cell kill by the combination of 10-EDAM and DPM was no greater than 10-EDAM alone, consistent with the possibility that DPM exerts some of its effect by inhibition of extrinsic nucleoside salvage. In consideration of the published activity of 10-EDAM in lung cancer and the modest clinical toxicity of DPM based biochemical modulation, we conclude the current in vitro data provide justification for clinical evaluation of this combination in patients with lung cancer.
