Efforts in Bioprospecting Research: A Survey of Novel Anticancer Phytochemicals Reported in the Last Decade. Molecules 2022; 27:molecules27238307. [PMID: 36500400 PMCID: PMC9738008 DOI: 10.3390/molecules27238307] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Revised: 11/10/2022] [Accepted: 11/22/2022] [Indexed: 11/30/2022] Open
Abstract
Bioprospecting natural products to find prominent agents for medical application is an area of scientific endeavor that has produced many clinically used bioactive compounds, including anticancer agents. These compounds come from plants, microorganisms, and marine life. They are so-called secondary metabolites that are important for a species to survive in the hostile environment of its respective ecosystem. The kingdom of Plantae has been an important source of traditional medicine in the past and is also enormously used today as an exquisite reservoir for detecting novel bioactive compounds that are potent against hard-to-treat maladies such as cancer. Cancer therapies, especially chemotherapies, are fraught with many factors that are difficult to manage, such as drug resistance, adverse side effects, less selectivity, complexity, etc. Here, we report the results of an exploration of the databases of PubMed, Science Direct, and Google Scholar for bioactive anticancer phytochemicals published between 2010 and 2020. Our report is restricted to new compounds with strong-to-moderate bioactivity potential for which mass spectroscopic structural data are available. Each of the phytochemicals reported in this review was assigned to chemical classes with peculiar anticancer properties. In our survey, we found anticancer phytochemicals that are reported to have selective toxicity against cancer cells, to sensitize MDR cancer cells, and to have multitarget effects in several signaling pathways. Surprisingly, many of these compounds have limited follow-up studies. Detailed investigations into the synthesis of more functional derivatives, chemical genetics, and the clinical relevance of these compounds are required to achieve safer chemotherapy.

Validation of survival prognostic models for non-small-cell lung cancer in stage- and age-specific groups. Lung Cancer 2015; 90:281-7. [PMID: 26319317 DOI: 10.1016/j.lungcan.2015.08.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2015] [Revised: 07/03/2015] [Accepted: 08/13/2015] [Indexed: 01/16/2023]
Abstract
PURPOSE Prognostic models have been proposed to predict survival for non-small-cell lung cancer (NSCLC). It is important to evaluate whether these models perform better than performance status (PS) alone in stage- and age-specific subgroups. PATIENTS AND METHODS The validation cohort included 2060 stage I and 1611 stage IV NSCLC patients from 23CALGB studies. For stage I, Blanchon (B), Chansky (C) and Gail (G) models were evaluated along with the PS only model. For stage IV, Blanchon (B) and Mandrekar (M) models were compared with the PS only model. The c-index was used to assess the concordance between survival and risk scores. The c-index difference (c-difference) and the integrated discrimination improvement (IDI) were used to determine the improvement of these models over the PS only model. RESULTS For stage I, B and PS have better survival separation. The c-index for B, PS, C and G are 0.61, 0.58, 0.57 and 0.52, respectively, and B performs significantly better than PS with c-difference=0.034. For stage IV, B, M and PS have c-index 0.61, 0.64 and 0.60, respectively; B and M perform significantly better than PS with c-difference=0.015 and 0.033, respectively. CONCLUSION Although some prognostic models have better concordance with survival than the PS only model, the absolute improvement is small. More accurate prognostic models should be developed; the inclusion of tumor genetic variants may improve prognostic models.

Abstract
BACKGROUND Patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) should be treated with first-line and second-line chemotherapy or target therapy according to the lung cancer guidelines. However, no recommended treatments are available after failure to these treatments. In our study, the efficacy and safety of combined chemotherapy of vinorelbine and ifosfamide as third-line therapy or beyond for advanced NSCLC was evaluated. METHODS A total of 41 patients took a combination of vinorelbine and ifosfamide as third-line or above chemotherapy in Peking Union Hospital between May 2010 and May 2014. They were pathologically or cytologically confirmed as having locally advanced or metastatic NSCLC. Clinically measurable lesions existed, and Eastern Cooperative Oncology Group performance status ranged from 0 to 2. No serious complications were observed in the hematopoietic system, and liver and renal functions were normal. RESULTS The 41 patients enrolled in this study were given 150 cycles of chemotherapy, of which 23 cycles (15.3%) were delayed or dose-adjusted. Results of the objective response evaluation showed that 3 cases had objective partial response (7.3%) and 25 cases were stable (61.0%). The median progression-free survival time was 5.5 months, and the median overall survival time was 10.5 months. Hematological toxicity was the most frequent adverse event. Grade 3/4 neutropenia had 10.7% occurrence; grade 3/4 white blood cell decrease had 8.7%; and grade 3/4 anemia had 8.7%. All adverse events were manageable, and no drug-related death was found. CONCLUSIONS Vinorelbine and ifosfamide as third-line treatment and beyond of NSCLC were well tolerated. Most patients can benefit from this combined chemotherapy. A clinical trial with large samples is necessary to prove whether overall survival will .

Abstract
PURPOSE In a retrospective analysis of the prevalence of KRAS mutations in patients with advanced non-small cell lung cancer (NSCLC), we detected a unique and not earlier described case of a double combination of mutations at codons 12 and 13 of the KRAS gene in a patient with lung adenocarcinoma. MATERIAL/METHODS To determine the molecular characteristics of the infrequent mutation and the mutational status of the KRAS gene in metastatic brain tumors in the same patient, we performed morphological and molecular tests. RESULTS Molecular analysis of the nature of the double mutation showed that the unique combination of variants is a monoallelic mutation. This type of changes has not yet been registered in the Catalogue of Somatic Mutations in Cancer database. Molecular assessment of the KRAS mutation status in the brain metastatic site in the same patient, showed no mutations in codons 12 and 13. Moreover, we did not find mutation at exon 19 and 21 of EGFR gene, both in primary tumor as well as in secondary metastatic foci in the brain. CONCLUSIONS The presented case shows an example of KRAS gene molecular mosaicism and heterogeneity of lung adenocarcinoma primary and metastatic tumors. Molecular heterogeneity of lung adenocarcinoma tumors can significantly affect eligibility of patients for targeted therapies.

Abstract
Background Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI) have been widely used for the treatment of non-small cell lung cancer (NSCLC). KRAS and EGFR somatic mutations in NSCLC may predict resistance and responsiveness to TKI, respectively. Nevertheless, most research to date has been conducted on samples from primary tumors. For many patients with advanced disease, their samples can only be obtained from metastases for test. The molecular characteristics of metastasized tumors may be different from those of primary tumors. Materials and methods Mutation status of KRAS and EGFR between primary tumors and local lymph node metastases of 80 Chinese patients with NSCLC were analyzed by direct sequencing. Five of them were given gefitinib as neoadjunvant treatment after the EGFR-TKI sensitive mutations were detected in their biopsies of mediastinal lymph nodes metastases. McNemar's test was used to compare the EGFR and KRAS mutation status between primary tumors and corresponding local lymph node metastases. Data evaluation was carried out with SPSS_13.0 statistical software. Results Among the 160 samples, one primary tumor and seven metastases were identified with KRAS mutations and 21 primary tumors and 26 metastases were found to have EGFR mutations. KRAS and EGFR mutation status was different between primary tumors and corresponding metastases in 6 (7.5%) and 7 (8.75%) patients, respectively. One patient with no TKI sensitive mutations detected in the primary tumor showed disease progression. Conclusion Our results suggest that a considerable proportion of NSCLC in Chinese population showed discrepancy in KRAS and EGFR mutation status between primary tumors and corresponding metastases. This observation may have important implication for the use of targeted TKI therapy in the treatment of NSCLC patients.

Abstract
Chemotherapeutic combination regimens for advanced non-small cell lung cancer traditionally have been based on platin compounds. However, a mechanistic rationale could lead to effective non-platin combinations. Paclitaxel and vinorelbine are antimicrotubule agents with different mechanisms of action, both of which have single agent activity against non-small cell lung cancer. A Phase I/II trial of paclitaxel Day 1 and vinorelbine Days 1-3 every 21 days was, therefore, performed for patients with Stage IIIB or Stage IV non-small cell lung cancer who had not previously received chemotherapy for metastatic disease. In the Phase I investigation, up to 4 patients were treated at each dose level. The maximum tolerated dose level was found to be paclitaxel 150 mg/m2 IV Day 1 and vinorelbine 16 mg/m2 IV Days 1-3, with dose-limiting toxicities of fatigue, myalgia, and mucositis at higher doses. This dose level was then expanded with an additional 15 patients. Of the 23 patients treated for up to 10 cycles at or near the maximum tolerated dose level (19 patients with paclitaxel 150 mg/m2 IV Day 1 and vinorelbine 16 mg/m2 Days 1-3, and 4 patients with paclitaxel 150 mg/m2 IV Day 1 and vinorelbine 13 mg/m2 Days 1-3), 7 patients achieved partial response and 5 patients achieved minor response. Fatigue, myalgia, peripheral neuropathy, and transient leukopenia were the most common cumulative toxicities seen. The non-platin chemotherapy doublet of paclitaxel and vinorelbine given on this convenient 3-day schedule is worthy of further investigation in the treatment of non-small cell lung cancer.

Abstract
PURPOSE A dose-escalation Phase I study of taxol (paclitaxel) administered in combination with standard dose ifosfamide was conducted in children with relapsed or refractory solid tumors. Primary objectives were to estimate the maximum tolerated dose (MTD) and to describe the dose-limiting toxicities (DLTs). PATIENTS AND METHODS Paclitaxel was administered as a 6-hr continuous infusion (hr 0-6), followed by intravenous ifosfamide (2 g/m(2)/day x 3 days) over 1 hr at hours 6-7, 24-25, and 48-49. Patients at dose level 1 received 250 mg/m(2) paclitaxel. Subsequent dose escalation proceeded using a standard 3 x 3 Phase I design. RESULTS Fifteen patients received a combined 46 courses of therapy. The median age was 14.5 years (range, 2-19 years), and diagnoses included sarcoma (7), neuroblastoma (3), and other (5). Three patients received paclitaxel at 250 mg/m(2) (10 courses), six at 325 mg/m(2) (19 courses), three at 425 mg/m(2) (8 courses), and three at 550 mg/m(2) (9 courses). DLTs occurred in 2/3 patients at 550 mg/m(2) paclitaxel during cycle 1, including grade 3 hypotension and grade 4 anaphylaxis in 1 patient each. Common non-dose-limiting toxicities included bone marrow suppression and peripheral neuropathy. Response was evaluable in 14 patients and included mixed response (3), stable disease (5), and progressive disease (6). CONCLUSION Paclitaxel hypersensitivity reactions were dose limiting when the drug was administered as a 6-hr infusion. The MTD and recommended Phase II dose of paclitaxel administered as a 6-hr continuous intravenous infusion followed by standard dose intravenous ifosfamide is 425 mg/m(2) paclitaxel.

Abstract
PURPOSE To investigate the effect of socioeconomic status, as measured by education, on the survival of 1,577 lung cancer patients treated on 11 studies conducted by the Cancer and Leukemia Group B. PATIENTS AND METHODS Sociodemographic data, including education, was reported by the patient at the time of clinical trial accrual. Cox proportional hazards model stratified by treatment arm/study was used to examine the effect of education on survival after adjustment for known prognostic factors. RESULTS The patient population included 1,177 patients diagnosed with non-small-cell lung cancer (NSCLC; stage III or IV) and 400 patients diagnosed with small-cell lung cancer (SCLC; extensive or limited). Patients with less than an eighth grade education (13% of patients) were significantly more likely to be male, nonwhite, and older; have a performance status (PS) of 1 or 2; and have chest pain. Significant predictors of poor survival in the final model included male sex, PS of 1 or 2, dyspnea, weight loss, liver or bone metastases, unmarried, presence of adrenal metastases and high alkaline phosphatase levels among patients with NSCLC, and high WBC levels among patients with advanced disease. Education was not predictive of survival. CONCLUSION The physical condition of patients with low education who enroll onto clinical trials is worse than patients with higher education. Once enrolled onto a clinical trial, education does not affect the survival of patients with SCLC or stage III or IV NSCLC. The standardization of treatment and follow-up within a clinical trial, regardless of education, is one possible explanation for this lack of effect.

Abstract
OBJECTIVE The goal of this study was to determine the effectiveness of taxane-containing regimens versus non-taxane-containing regimens using a metanalysis and its subsequent pharmacoeconomic assessment to define the role of taxanes as first-line therapy for non micro-cytic lung cancer. METHOD A search of the MEDLINE database from 2000 to June 2005 was performed. The search was restricted to phase-III clinical trials, and 29 papers were selected. Effectivity measures considered included: objective response, 1- and 2-year survival. Maentel-Haenszel combined odds ratio (OR) was estimated in the metanalysis. The statistical analysis of effectiveness across categories was performed using a one-way analysis of variance (ANOVA). Differences were statistically considered for p values = 0.01. All results obtained were weighted according to number of patients. RESULTS OR estimates for the various effectiveness variables showed statistically significant differences when 2-year survival was considered both for taxanes in general and docetaxel specifically versus non-taxane regimens. These same results are seen when the effectiveness analysis is performed using ANOVA. For the pharmacoeconomic analysis taxane-free regimens were considered as reference, this being of choice for comparisons versus paclitaxel-containing regimens whereas the selection of docetaxel-containing schemes represents additional costs per extra effectiveness unit that oscillate between 26,559 and 96,527 (2-year survival and objective response, respectively) versus taxane-free regimens. The sensitivity analysis ultimately confirmed our study s results. CONCLUSIONS To conclude, taxane-containing schemes are valid therapeutic options, but at a very high cost.

Abstract
UNLABELLED This evidence-based practice guideline on the use of paclitaxel (Taxol) or docetaxel (Taxotere) as first-line treatment for patients with advanced non-small cell lung cancer who are candidates for palliative first-line chemotherapy is based on a systematic search and review of literature published in full or in abstract form between 1985 and April 2005. Forty-five randomized trials, including 11 abstracts, were reviewed and clinicians in the province of Ontario, Canada, provided feedback on a draft version of the guideline. Two phase III trials detected a statistically significant survival advantage for a taxane (paclitaxel or docetaxel) with best supportive care versus best supportive care alone. Among the nine fully published phase III trials comparing platinum-based chemotherapies, taxane-platinum combinations achieved higher response rates compared with older chemotherapy combinations, although significantly longer survival was observed only for docetaxel-cisplatin compared with vindesine-cisplatin. Response rates and survival were generally not significantly different for taxane-platinum combinations compared with other current chemotherapy combinations, although the toxicity profile of the regimens varied. However, in one large trial, improved tumor response and modest survival and quality of life benefits were associated with docetaxel-cisplatin compared with vinorelbine-cisplatin. No statistically significant survival differences were detected in the three fully published phase III trials comparing a taxane-gemcitabine combination with a taxane-platinum regimen. RECOMMENDATIONS (i) paclitaxel or docetaxel combined with cisplatin is recommended as one of a number of chemotherapy options for the first-line treatment of advanced non-small cell lung cancer in patients with a good performance status; (ii) carboplatin may be combined with a taxane if a patient is unable or unwilling to take cisplatin; (iii) a taxane-gemcitabine combination may be considered for patients with a contraindication to cisplatin and carboplatin; (iv) no firm recommendation can be made on the optimal dose and schedule of taxane-based chemotherapy; however, commonly used regimens include cisplatin 75 mg/m2 combined with either docetaxel 75 mg/m2 or paclitaxel 135 mg/m2 (24-h infusion) and carboplatin AUC 6 combined with paclitaxel 225 mg/m2 (3-h infusion); (v) a single-agent taxane may be used if combination chemotherapy is considered inappropriate.

Abstract
BACKGROUND To evaluate the activity and tolerability of gemcitabine plus irinotecan or docetaxel as first-line chemotherapy for advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS Eligible patients with chemotherapy-naïve stage IIIB or IV NSCLC were randomized to receive gemcitabine 1000 mg/m2 on days 1 and 8, plus either irinotecan 100 mg/m2 or docetaxel 40 mg/m2 on days 1 and 8. Treatment was administered every 3 weeks. RESULTS Of the 80 enrolled patients with stage IIIB or IV NSCLC, 78 were evaluable for activity and safety. Overall response rates, consisting of partial responses, were 12.8% [95% confidence interval (CI) 4% to 35%] for gemcitabine-irinotecan and 23.1% (95% CI 10% to 42%) for gemcitabine-docetaxel. Median overall survival was 7.95 months (95% CI 5.2-10.2) and 12.8 months (95% CI 7.9-17.1) for gemcitabine-irinotecan and gemcitabine-docetaxel, respectively. The corresponding estimated 1-year survivals were 23% and 51%, respectively. The 2-year survival rate in arm A (gemcitabine-irinotecan) is not currently estimable. The 2-year survival rate for arm B (gemcitabine-docetaxel) is 22% (95% CI 6% to 37%). Both combinations were well tolerated; the most common hematological toxicity was neutropenia, which occurred in 26% of patients in each treatment arm. CONCLUSIONS These results suggest that gemcitabine plus docetaxel or irinotecan is well tolerated in patients with chemotherapy-naïve advanced NSCLC. The survival data with the combination gemcitabine-docetaxel are promising. Gemcitabine-docetaxel combination therapy may be particularly useful for patients who have experienced toxicities with a platinum regimen or in patients who may be more susceptible to platinum-related toxicity.

BACKGROUND The aim of this study was to evaluate feasibility and tolerability of the three-drug combination of paclitaxel, ifosfamide and carboplatin (TIC) in patients with advanced non-small-cell lung cancer. The specific objectives of the study were: (i) to define the dose-limiting toxicities (DLTs) and the maximum-tolerated dose of ifosfamide administered as part of the combination; and (ii) to determine the overall response rate and overall survival of patients treated with this regimen. PATIENTS AND METHODS Patients with untreated, stage IIIB (pleural effusion) or stage IV non-small-cell lung cancer were enrolled in one of three cohorts. Patients received paclitaxel 200 mg/m(2) as a 1-h infusion on day 1 with carboplatin at an area under the concentration-time curve (AUC) of 6 mg.min/ml on day 2. For dose level I, ifosfamide was administered at a dose of 2 g/m(2) on days 1 and 2. For dose levels II and III, the dose of ifosfamide was decreased to 1.5 g/m(2) on days 1 and 2 and the dose of carboplatin was decreased to AUC 5 mg.ml/min. Therapy for dose levels I and III included filgrastim support (5 micro g/kg/day), which was initiated on day 3 and continued until after day 11 or until an absolute neutrophil count >10 000/ micro l. Treatment cycles were repeated every 21 days. Once the phase II dose was established, a full cohort of patients received therapy at this dose level to examine further the regimen's activity and tolerability. RESULTS Neutropenia was the DLT encountered for dose levels I and II. No DLT was encountered in the initial six patients treated at dose level III, and therefore this dose level was declared the recommended phase II dose. A total of 49 patients were treated at the recommended phase II dose. The predominant non-hematological toxicity encountered with this triplet regimen was cumulative peripheral neuropathy. Of the 65 eligible patients enrolled in this study, 17 (26%) responded. There were 15 patients with partial responses (23%), two with regression, and 26 with stabilization of disease (40%). Median progression-free and overall survival were 4.8 and 9.4 months, respectively. CONCLUSIONS The combination TIC is well-tolerated. This triplet regimen produced response and survival rates in advanced non-small-cell lung cancer similar to those of other current combination chemotherapy regimens.

Abstract
Platinum-based combination and single-agent chemotherapy have become accepted as treatments for locally advanced and metastatic nonsmall cell lung cancer as a consequence of improved survival, quality of life, and symptom control compared with best supportive care. However, it is clear that a therapeutic plateau has been reached with current combinations requiring a re-evaluation of strategies to improve clinical outcomes. Dose intensification may offer one way in which to achieve better results, as may extension of the duration of treatment. The evidence suggests that dose intensification is a useful tool, and that its use in combination with markers of treatment duration and cumulative dose may help to maximize results from current active drug combinations.

Abstract
BACKGROUND Among patients diagnosed with advanced non-small-cell lung carcinoma (NSCLC), African-Americans have lower survival rates than non-African-Americans. Whether this difference is due to innate characteristics of the disease in the two ethnicities or to disparities in health care is not known. We investigated whether the disparity in survival would persist when patients were treated with similar systemic therapies (i.e., in phase II and phase III Cancer and Leukemia Group B [CALGB] trials). METHODS We assessed 504 consecutive patients (458 non-African-American and 46 African-American) receiving systemic chemotherapy in CALGB studies for advanced NSCLC during the period from 1989 through 1998. Clinical and demographic characteristics, treatment received, and survival data were obtained from the CALGB database. Cox's proportional hazards model was used to assess the effect of race/ethnicity on survival after adjustment for other known prognostic factors. All statistical tests were two-sided. RESULTS The unadjusted 1-year survival rate was 22% (95% confidence interval [CI] = 13% to 38%) for African-American patients and 30% (95% CI = 26% to 35%) for non-African-American patients, a statistically significant difference (8%; 95% CI on the difference = 5% to 12%; P =.03). Multivariable adjustment for the effect of treatment arm, histology, and metastatic site at presentation did not alter the worse outcome for African-American patients. However, the effect of race/ethnicity disappeared after adjustment for performance status and weight loss. African-American patients were more likely than non-African-Americans to present with a poor performance status (83% versus 60%) and substantial weight loss (41% versus 27%) and to be unmarried (59% versus 28%), disabled (31% versus 15%), unemployed (17% versus 7%), and Medicaid recipients (30% versus 8%). CONCLUSIONS The relationship that we observed between poor performance, weight loss, and socioeconomic status suggests that social circumstances lead to African-Americans presenting with poorer prognostic features.

Abstract
BACKGROUND Lung cancer remains a devastating disease with few effective treatment options. Recent developments in chemotherapy have led to cautious optimism. This paper reviews the evidence on the clinical and cost effectiveness of four of the new generation drugs for patients with lung cancer. METHODS A systematic review of randomised controlled trials (RCTs) identified from 11 electronic databases (including Medline, Cochrane library and Embase), reference lists and contact with experts and industry was performed to assess clinical effectiveness of paclitaxel, docetaxel, gemcitabine and vinorelbine. Clinical effectiveness was assessed using the outcomes of patient survival, quality of life, and adverse effects. Cost effectiveness was assessed by development of a costing model and presented as incremental cost per life year saved (LYS) compared with best supportive care (BSC). RESULTS Of the 33 RCTs included, five were judged to be of good quality, 10 of adequate quality, and 18 of poor quality. Gemcitabine, paclitaxel, and vinorelbine as first line treatment and docetaxel as second line treatment appear to be more beneficial for non-small cell lung cancer than BSC and older chemotherapy agents, increasing patient survival by 2-4 months against BSC and some comparator regimes. These gains in survival do not appear to be at the expense of quality of life. Survival gains were delivered at reasonable levels of incremental cost effectiveness for vinorelbine, vinorelbine with cisplatin, gemcitabine, gemcitabine with cisplatin, and paclitaxel with cisplatin regimens compared with BSC. CONCLUSION Although the clinical benefits of the new drugs appear relatively small, their benefit to patients with lung cancer appears to be worthwhile and cost effective.

Abstract
BACKGROUND Our goal was to assess the effectiveness of paclitaxel therapy in patients with non-small-cell lung cancer (NSCLC) by means of a meta-analysis of published clinical trials. MATERIAL AND METHOD We carried out a search of controlled and randomized clinical trials which evaluated treatment with paclitaxel in patients with NSCLC from January 1996 to April 2001, regardless of any other associated therapy and without restrictions in the publication language. We also performed a sensitivity analysis and an analysis of sample heterogeneity. RESULTS Six randomized and controlled studies fulfilled the inclusion criteria. Results from the analysis of effectiveness favoured significantly treatment with paclitaxel (OR 95% total responders: 1.42 [1.16-1.74]; p = 0.07). These results remained unchanged with the sensitivity analysis. Analysis of survival after 1 year of treatment was not significant (OR 95% 0.96 [0.79-1.17]; p = 0.2) CONCLUSIONS Paclitaxel in patients with NSCLC offers a therapeutic advantage over other chemotherapy regimes with an overall OR of 1.42. However, this therapy does not appear to offer a significant survival advantage after 1 year.

Abstract
The introduction of new agents in the treatment of lung cancer raised in the past few years new interest in clinical research on this topic. The use of taxanes as paclitaxel and docetaxel may represent a significant progress in the treatment of lung cancer. Taxanes used as single agents show a substantial activity in lung cancer and, because of their unique mechanism of action, it is possible to combine these drugs with other non-cross-resistant agents. Taxanes share a radiosensitizing effect and their use with concurrent radiotherapy appears to become a new standard. This review will focus on the European clinical experience in the treatment of lung cancer with the two compounds.
