Real-world outcomes in patients with KRAS G12C-mutated advanced non-small cell lung cancer treated with docetaxel in second-line or beyond. Lung Cancer 2023; 181:107260. [PMID: 37285629 DOI: 10.1016/j.lungcan.2023.107260] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Revised: 05/17/2023] [Accepted: 05/22/2023] [Indexed: 06/09/2023]
Abstract
INTRODUCTION The KRAS G12C mutation has recently become a druggable target in non-small cell lung cancer (NSCLC). In this observational study, we present real-world clinicopathological characteristics, treatment patterns, and survival outcomes data in patients with KRAS mutation-positive advanced NSCLC (aNSCLC), including those with KRAS G12C and KRAS non-G12C mutations, who received docetaxel as standard-of-care treatment in the second-line and beyond (2L+). METHODS US-based electronic health record-derived de-identified databases were used to assess clinicopathological characteristics and outcomes in adult aNSCLC patients with KRAS mutations treated with 2L+ docetaxel between January 1, 2011, and March 31, 2021. The primary endpoints were median real-world overall survival OS (rwOS) and median real-world progression-free survival (rwPFS), which were estimated in 2L, third-line, fourth-line, and 2L+ analysis sets among patients who had a 6-month minimum opportunity for follow-up and were not taking a clinical trial drug. RESULTS Of the 677 patients with KRAS-mutant aNSCLC (KRAS mutant cohort) treated with 2L+ docetaxel, 295 (43.6%) had KRAS G12C mutation (KRAS G12C cohort) and 382 (56.4%) had KRAS non-G12C mutation (KRAS non-G12C cohort). Across all cohorts, approximately 47%, 35%, 14-15%, and 6-9% of patients received 2L, third-line, fourth-line, and fifth- or later-line docetaxel, respectively. In the KRAS G12C cohort, ∼68% of patients were treated with a PD-1/PD-L1 inhibitor prior to 2L+ docetaxel. Most 2L+ docetaxel regimens in the KRAS G12C cohort were combinations (59.5%), primarily with ramucirumab (45.2%). In the KRAS G12C cohort, the median rwOS and median rwPFS after 2L+ docetaxel were 6.0 (95% CI, 4.9-7.1) and 3.4 (95% CI, 2.7-4.2) months, respectively, with similar trends observed in other cohorts and lines of therapy. CONCLUSIONS Real-world outcomes were poor in patients with KRAS G12C-mutated aNSCLC treated with 2L+ docetaxel. Targeted and more efficacious treatment options in these patients are warranted.

Abstract
BACKGROUND This study aimed to quantitatively evaluate factors influencing the efficacy and safety of the docetaxel-platinum regimen to provide reliable information for optimizing chemotherapy regimens. RESEARCH DESIGN AND METHODS A parametric survival function model was used to describe the time course of overall survival (OS) of patients with advanced non-small cell lung cancer (NSCLC) receiving a docetaxel-platinum regimen. A random-effects model in a single-arm meta-analysis was used to analyze the objective response rate and grade 3-4 adverse event rates based on various docetaxel-platinum regimens. RESULTS The model revealed that the risk of death in East Asians was approximately 1.5-fold higher than that in non-East Asians, with a median OS of 13.7 (95% confidence interval [CI]: 12.8-14.7) months and 9.3 (95% CI: 7.7-11.1) months, respectively. No significant impact of different administration regimens on OS was found. However, when drug exposure increased, the incidence of grade 3-4 anemia or neutropenia significantly increased. CONCLUSIONS The docetaxel-platinum regimen has different efficacies in the treatment of advanced NSCLC between East Asian and non-East Asian populations. A better benefit-risk ratio can be obtained with a lower exposure regimen of docetaxel combined with platinum.

Afatinib versus erlotinib as second-line treatment of patients with advanced squamous cell carcinoma of the lung: Final analysis of the randomised phase 3 LUX-Lung 8 trial. EClinicalMedicine 2021; 37:100940. [PMID: 34195574 PMCID: PMC8225678 DOI: 10.1016/j.eclinm.2021.100940] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Revised: 05/12/2021] [Accepted: 05/14/2021] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND LUX-Lung 8 was a randomised, controlled, phase 3 study comparing afatinib and erlotinib as second-line treatment of patients with advanced squamous cell carcinoma (SCC) of the lung. We report the final overall survival (OS) and safety analyses of LUX-Lung 8 and investigate the characteristics of patients who achieved long-term benefit (≥12 months' treatment). METHODS LUX-Lung 8 (NCT01523587) enroled patients between March 2012 and January 2014 in 183 cancer centres located in 23 countries worldwide and this final analysis had a data cut-off of March 2018. Eligible patients had stage IIIB or IV lung SCC and had progressed after at least four cycles of platinum-based chemotherapy. Patients were randomly assigned (1:1) to receive afatinib (40 mg per day) or erlotinib (150 mg per day) until disease progression. Endpoints included OS and safety; a post-hoc analysis of patients with long-term benefit (≥12 months on treatment) was also conducted. FINDINGS 795 eligible patients were randomly assigned (398 to afatinib, 397 to erlotinib). OS was significantly prolonged with afatinib compared with erlotinib (median 7·8 months vs 6·8 months; hazard ratio 0·84; 95% CI 0·73-0·97; p = 0·0193). These findings were consistent with those of the primary analysis and were consistent across subgroups. Adverse events (AEs) were manageable with dose interruption and reduction, with similar AEs being experienced between both groups. Twenty-one (5·3%) patients receiving afatinib and 13 (3·3%) patients receiving erlotinib achieved long-term benefit; median OS was 34·6 months and 20·1 months, respectively. Amongst 132 afatinib-treated patients who underwent tumour genetic analysis, ERBB family mutations were more common in patients with long-term benefit than in the overall population (50% vs 21%). INTERPRETATION Afatinib is a treatment option for patients with SCC of the lung progressing on chemotherapy who are ineligible for immunotherapy, particularly those with ERBB family genetic aberrations. Afatinib has a predictable and manageable tolerability profile, and long-term treatment may be well tolerated.

Abstract
OBJECTIVE The results from basket trials utilized to gain regulatory approval of tumor-agnostic therapies can be difficult to interpret without the context of a comparator arm. We describe the role and efficacy of histology-based treatments to provide a historical comparison with larotrectinib. METHODS A systematic literature review (SLR) was conducted on the clinical outcomes of current histology-based standard of care treatments used in non-small cell lung cancer, colorectal cancer, thyroid cancer, gliomas, soft tissue sarcoma, salivary gland cancer, and infantile fibrosarcoma (7 of the 21 tumor histologies in the larotrectinib trials). The review focused on advanced stage/metastatic disease to make a historical comparison with larotrectinib. RESULTS Larotrectinib provides positive outcomes in both adult and pediatric patients with advanced or metastatic solid tumors known to harbor NTRK gene fusions across a wide range of tumor types. Although the numbers of patients per tumor type are limited, the results of this historical comparison demonstrated that larotrectinib is an efficacious treatment option when naïvely indirectly compared with historical treatments across all 7 reviewed tumor types, especially in comparison to later lines of therapy. CONCLUSIONS Utilizing larotrectinib as a case example across these types of historical comparisons shows that larotrectinib provides positive efficacy outcomes in TRK fusion cancer across tumor histologies known to harbor NTRK gene fusions that may be preferable to historical treatments.

Upfront dose-reduced chemotherapy synergizes with immunotherapy to optimize chemoimmunotherapy in squamous cell lung carcinoma. J Immunother Cancer 2020; 8:jitc-2020-000807. [PMID: 33115941 PMCID: PMC7594539 DOI: 10.1136/jitc-2020-000807] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/29/2020] [Indexed: 12/25/2022] Open
Abstract
Background The survival benefits of combining chemotherapy (at the maximum tolerated dose, MTD) with concurrent immunotherapy, collectively referred to as chemoimmunotherapy, for the treatment of squamous cell lung carcinoma (SQCLC) have been confirmed in recent clinical trials. Nevertheless, optimization of chemoimmunotherapy in order to enhance the efficacy of immune checkpoint inhibitors (ICIs) in SQCLC remains to be explored. Methods Cell lines, syngeneic immunocompetent mouse models, and patients’ peripheral blood mononuclear cells were used in order to comprehensively explore how to enhance ectopic lymphoid-like structures (ELSs) and upregulate the therapeutic targets of anti-programmed death 1 (PD-1)/anti-PD-1 ligand (PD-L1) monoclonal antibodies (mAbs), thus rendering SQCLC more sensitive to ICIs. In addition, molecular mechanisms underlying optimization were characterized. Results Low-dose chemotherapy contributed to an enhanced antigen exposure via the phosphatidylinositol 3-kinase/Akt/transcription factor nuclear factor kappa B signaling pathway. Improved antigen uptake and presentation by activated dendritic cells (DCs) was observed, thus invoking specific T cell responses leading to systemic immune responses and immunological memory. In turn, enhanced antitumor ELSs and PD-1/PD-L1 expression was observed in vivo. Moreover, upfront metronomic (low-dose and frequent administration) chemotherapy extended the time window of the immunostimulatory effect and effectively synergized with anti-PD-1/PD-L1 mAbs. A possible mechanism underlying this synergy is the increase of activated type I macrophages, DCs, and cytotoxic CD8+ T cells, as well as the maintenance of intestinal gut microbiota diversity and composition. In contrast, when combining routine MTD chemotherapy with ICIs, the effects appeared to be additive rather than synergistic. Conclusions We first attempted to optimize chemoimmunotherapy for SQCLC by investigating different combinatorial modes. Compared with the MTD chemotherapy used in current clinical practice, upfront metronomic chemotherapy performed better with subsequent anti-PD-1/PD-L1 mAb treatment. This combination approach is worth investigating in other types of tumors, followed by translation into the clinic in the future.

No relation between docetaxel administration route and high-grade diarrhea incidence. Pharmacol Res Perspect 2020; 8:e00633.

Abstract
Oral administration of docetaxel in combination with the CYP3A4 inhibitor ritonavir is used in clinical trials to improve oral bioavailability of docetaxel. Diarrhea was the most commonly observed and dose-limiting toxicity. This study combined preclinical and clinical data and investigated incidence, severity and cause of oral docetaxel-induced diarrhea. In this study, incidence and severity of diarrhea in patients were compared to exposure to orally administered docetaxel. Intestinal toxicity after oral or intraperitoneal administration of docetaxel was further explored in mice lacking Cyp3a and mice lacking both Cyp3a and P-glycoprotein. In patients, severity of diarrhea increased significantly with an increase in AUC and Cmax (P = .035 and P = .025, respectively), but not with an increase in the orally administered dose (P = .11). Furthermore, incidence of grade 3/4 diarrhea after oral docetaxel administration was similar as reported after intravenous docetaxel administration. Intestinal toxicity in mice was only observed at high systemic exposure to docetaxel and was similar after oral and intraperitoneal administration of docetaxel. In conclusion, our data show that the onset of severe diarrhea after oral administration of docetaxel in humans is similar after oral and intravenous administration of docetaxel and is caused by the concentration of docetaxel in the systemic blood circulation. Mouse experiments confirmed that intestinal toxicity is caused by a high systemic exposure and not by local intestinal exposure. Severe diarrhea in patients after oral docetaxel is reversible and is not related to the route of administration of docetaxel.

Abstract
Introduction: The treatment of lung cancer is not defined in the third-line setting and remains an unanswered question. Erlotinib is the only drug approved in the third-line setting. With the introduction of effective first- and second-line therapies, more and more patients warrant an effective third-line therapy. We did a post hoc analysis of our randomized trial for the epidermal growth factor receptor (EGFR)-positive patients who received third-line therapy. Materials and Methods: The present series is of 85 patients who received third-line therapy. Demographic data were collected which included age, performance status, gender, stage, comorbidities, and sites of metastasis. Data were collected for the type of systemic treatment patients received and number of cycles received. Information related to the impact of treatment on the symptoms of patients and the imaging done for response evaluation was collected. Results: Of the 85 patients, there were 13 patients (15%) who achieved a partial response and 34 patients (40%) who had stable disease as best response. There were no complete response and 20 patients (24%) had disease progression at the time of first assessment. The median overall survival (OS) was 8.36 months (95% confidence interval [CI] 6.8–9.8 months) and median progression-free survival was 4.4 months (95% CI 3.3–4.9 months). Grade 3 or 4 toxicities were seen in 42.5% (n = 36) of the total patients. Conclusions: The study provides the patterns and outcomes of systemic treatment in metastatic EGFR-mutated lung adenocarcinoma in patients who have progressed on two or more lines of systemic therapies. This data suggest that third-line systemic therapy may provide meaningful outcomes in these patients.

Comparative Efficacy of Second- and Subsequent-line Treatments for Metastatic NSCLC: A Fractional Polynomials Network Meta-analysis of Cancer Immunotherapies. Clin Lung Cancer 2019; 20:451-460.e5.

Abstract
BACKGROUND Extended onset of treatment effect and longer-term survival with anti-programmed death-ligand 1 (PD-L1)/programmed cell death protein 1 (PD-1) immunotherapies, atezolizumab, nivolumab, and pembrolizumab, have changed the landscape of second- or subsequent-line (2L+) treatments for adults with non-small-cell lung cancer (NSCLC). This systematic literature review included phase I to IV randomized, controlled trials of 2L+ NSCLC therapies from MEDLINE, Embase, and secondary sources. MATERIALS AND METHODS Studies of treatments approved in the European Union or United States had to be in English with ≥ 10 patients per arm. A fractional polynomials network meta-analysis (NMA) was conducted because traditional NMA of hazard ratios does not account for delayed onset of clinical effect or long-term survival observed in PD-L1/PD-1 inhibitor trials. Adjusted analyses accounted for treatment switching in the atezolizumab OAK trial. Expected survival time reflected area under the curve over the time horizon. Expected overall survival (OS) was ranked by median ranking with 95% credible intervals and by surface under the cumulative ranking curve. Of 25,115 screened records, 28 studies were included in the quantitative analyses of OS and progression-free survival. RESULTS PD-L1/PD-1 inhibitors had comparable expected 5-year OS; all performed better than other treatment options. In unadjusted analyses, surface under the cumulative ranking curve ranked nivolumab first (87.9%), followed by atezolizumab (85.8%) and pembrolizumab (82.8%). Analyses adjusted for patients switching from docetaxel to immunotherapy ranked atezolizumab first (89.6%), followed by nivolumab (86.5%) and pembrolizumab (81.9%). CONCLUSION This NMA applied an appropriate approach for indirect comparisons, including cancer immunotherapies, and supported robustness of PD-L1/PD-1 immunotherapies for 2L+ treatment of NSCLC.

Abstract
BACKGROUND Locally advanced or metastatic non-small cell lung cancer (NSCLC) that has progressed after first-line treatment has a poor prognosis. Recent randomized clinical trials (RCTs) have demonstrated survival benefits of alternative treatments to docetaxel. However, information is lacking on which patients benefit the most and what drug or regimen is optimal. We report a systematic review and network meta-analysis (NMA) of second-line treatments in all subgroup combinations determined by histology, programmed death ligand 1 (PD-L1) expression, and epidermal growth factor receptor (EGFR) mutation. METHODS MEDLINE, PubMed, EMBASE, Biosciences Information Service (using the Dialog Platform), Cochrane Library, and abstracts from scientific meetings were searched for RCTs published up to September 2015. Key outcomes were overall survival (OS) and progression-free survival (PFS). Bayesian hierarchical exchangeable NMAs were conducted to calculate mean survival times and relative differences for eight subgroups, using docetaxel as the reference comparator. For OS, the NMA was based on hazard ratios applied to a first-order fractional polynomial model fitted to the reference treatment. For PFS, a second-order fractional polynomial model was fitted to reconstructed patient-level data for the entire network of evidence. RESULTS The search identified 30 studies containing 17 different treatment regimens. Docetaxel plus ramucirumab was associated with a significant improvement in OS and PFS, relative to docetaxel, regardless of patient type. Docetaxel plus nintedanib showed similar efficacy to docetaxel plus ramucirumab in the nonsquamous populations. EGFR tyrosine kinase inhibitors (TKIs) erlotinib and gefitinib showed superior levels of efficacy in EGFR mutation-positive populations and the one PD-1 immunotherapy (nivolumab) studied showed superior efficacy in the populations exhibiting high PD-L1 expression. CONCLUSIONS In the absence of head-to-head comparisons, we performed a mixed-treatment analysis to synthesize evidence of the efficacy of each treatment. Benefits are optimized by targeting specific treatments to individual patients guided by histology, PD-L1 expression, and EGFR mutation status.

Abstract
The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of metastatic non-small-cell lung cancer (NSCLC) was published in 2016. At the ESMO Asia Meeting in November 2017 it was decided by both ESMO and the Chinese Society of Clinical Oncology (CSCO) to convene a special guidelines meeting immediately after the Chinese Thoracic Oncology Group Annual Meeting 2018, in Guangzhou, China. The aim was to adapt the ESMO 2016 guidelines to take into account the ethnic differences associated with the treatment of metastatic NSCLC cancer in Asian patients. These guidelines represent the consensus opinions reached by experts in the treatment of patients with metastatic NSCLC representing the oncological societies of China (CSCO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), Singapore (SSO) and Taiwan (TOS). The voting was based on scientific evidence, and was independent of both the current treatment practices and the drug availability and reimbursement situations in the six participating Asian countries. During the review process, the updated ESMO 2018 Clinical Practice Guidelines for metastatic NSCLC were released and were also considered, during the final stages of the development of the Pan-Asian adapted Clinical Practice Guidelines.

Abstract
Background Docetaxel is one of the standard treatments for advanced non-small cell lung cancer. Docetaxel is usually administered in a 3-week schedule, but there is significant toxicity. In this phase II clinical study, we investigated the efficacy and safety of a 4-weekly schedule of docetaxel monotherapy, as first-line chemotherapy for advanced squamous cell carcinoma in elderly lung cancer patients. Methods Patients with stage IIIB/ IV lung squamous-cell carcinoma age 70 or older, that had not undergone cytotoxic chemotherapy were enrolled. Patients received docetaxel 25 mg/m2 on days 1, 8, and 15, every 4 weeks. Primary endpoint was the objective response rate (ORR). Secondary endpoints were progression-free survival (PFS), overall survival (OS), and toxicity profiles. Results A total of 19 patients were enrolled. Among 19 patients, 17 were for evaluated efficacy and safety. In the intent-to-treat population, ORR and disease control rate (DCR) were 11.8% and 47.1%, respectively. In the response evaluable population, ORR was 16.7% and DCR was 66.7%. Median PFS and OS were 3.1 months and 3.3 months, respectively. There were three adverse grade 3/4 events. Grade 1 neutropenia was reported in one patient. Conclusion Our data failed to demonstrate efficacy of a 4-weekly docetaxel regimen, in elderly patients with a poor performance status. However, incidence of side effects, including neutropenia, was lower than with a 3-week docetaxel regimen, as previously reported.

In 2005, we included wPCT 80 mg/m for 6 consecutive weeks, followed by a 2-week interval in our department's everyday clinical practice guidelines for the second-line (or subsequent) treatment of patients with nonsquamous histologies who have previously received pemetrexed-based treatments and patients with squamous histology. In the absence of clinical evidence of disease progression, patients repeat the pretreatment staging procedures after 16 weeks (two cycles) and, in the absence of disease progression or severe toxicity, continue treatment for a maximum of four courses. Between May 2005 and December 2013, we treated 60 patients (47 in second-line and 13 in third/fourth line), who received a median of two courses (range: 1-4). The most frequent toxicity was grade 1-2 neutropaenia (five patients); only four patients experienced grade 3-4 toxicity. When used as a second-line treatment, wPCT led to a disease control rate of 36.2%, with a median progression-free survival of 3.7 months and a median overall survival of 9.0 months; when used in the third/fourth line, the disease control rate was 41.7%, the median progression-free survival was 5.0 months and the median overall survival was 10.3 months. Our data confirm that wPCT is active and well tolerated in an unselected patient population with aNSCLC and can be considered a valuable alternative to docetaxel in a second-line treatment.

Abstract
INTRODUCTION The treatment of lung cancer has radically changed over the last few years. The discovery of druggable oncogenic alterations and the introduction of immunotherapy have provided lung cancer patients with the possibility of more efficient and less toxic therapeutic alternatives than chemotherapy. In the case of lung squamous cell carcinoma (LSCC), the treatment progress is slower than adenocarcinoma, for which several targeted agents have been already approved. The standard first-line therapy for LSCC, in most sites of the world, is platinum-based chemotherapy. After disease progression, these patients now have novel treatment options, including antiangiogenic agents and immune checkpoint blockade. Areas covered: We provide a summary of the recent novelties for the second-line therapy of LSCC, emphasizing on the results of the most important clinical trials that have led to regulatory approvals. Expert commentary: Immune checkpoint inhibitors have changed the therapeutic algorithm for LSCC patients. Other treatment options in the second-line setting include ramucirumab in combination with docetaxel and afatinib. However, we still lack biomarkers to predict which patients could respond better to each treatment. Despite the identification of several actionable molecular alterations, there are no approved targeted agents specific for advanced LSCC. Results from ongoing biomarker-driven studies are eagerly awaited to establish effective treatments for molecularly selected subgroups of patients.

Abstract
Innovative therapeutic agents have significantly improved outcome with an acceptable safety profile in a substantial proportion of non-small cell lung cancer (NSCLC) patients, who depend on oncogenic molecular alterations for their malignant phenotype. Despite the survival improvement achieved with first-line chemotherapy, about 30% of patients do not obtain a tumor response. Moreover, those patients, initially sensitive to treatment, acquire resistance and develop tumor progression after a median of about 5 months. Approximately 60% of the patients progressing from first-line chemotherapy receive further systemic treatment in the second-line setting. Moreover, new options have emerged in the second-line armamentarium for the treatment of patients with NSCLC, including immune checkpoint inhibitors and antiangiogenic agents. The current review provides an overview on the clinical studies that gained the approval of chemotherapy agents (docetaxel and pemetrexed) and epidermal growth factor receptor gene–tyrosine kinase inhibitors as second-line treatment options for NSCLC patients, not carrying molecular alterations.

Abstract
INTRODUCTION Non-small cell lung cancer lung cancer (NSCLC) is a devastating disease, with poor prognosis for patients with metastatic disease. The management of these patients has evolved during the past decade, challenging the role of cytotoxic chemotherapy as the only available treatment option. Nevertheless, chemotherapy still retains a dominant position for the majority of both treatment naïve and pretreated patients. Among the chemotherapeutic agents, docetaxel is one of the most commonly used in 1st and subsequent treatment lines, even in the current era of precision medicine. Areas covered: We searched Medline, Embase, Scopus and Cochrane Library for randomized phase III trials that evaluated docetaxel in various clinical settings of NSCLC and for meta-analyses of such trials and we present all relevant data regarding the pharmacology and clinical use of docetaxel in NSCLC. Expert commentary: Despite its diminishing role, docetaxel in combination with novel targeted agents remains an important option of the therapeutic armamentarium in advanced NSCLC.

Consolidation chwemotherapy after concurrent chemoradiotherapy vs. chemoradiotherapy alone for locally advanced unresectable stage III non-small-cell lung cancer: A meta-analysis. Mol Clin Oncol 2016; 5:271-278. [PMID: 27446563 PMCID: PMC4950681 DOI: 10.3892/mco.2016.910] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2016] [Accepted: 05/09/2016] [Indexed: 12/25/2022] Open
Abstract
Concurrent chemoradiotherapy (CCRT) has been considered to be the standard of care for locally advanced unresectable stage III non-small-cell lung cancer (LA-NSCLC). Whether consolidation chemotherapy (CCT) following CCRT is able to further improve the clinical outcome remains unclear. We therefore undertook a meta-analysis to compare the two regimens for LA-NSCLC. A literature search was performed through PubMed, Embase, Cochrane Library and Chinese Biology Medicine, from their inception to November, 2015. Irrelevant studies were excluded using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards. Our primary endpoint was overall survival (OS), which was defined as the time from randomisation until death from any cause; the secondary endpoint was progression-free survival (PFS). All analyses were by intention-to-treat. Five phase III randomized controlled trials with 958 patients were included in the present meta-analysis. The results were expressed as odds ratios (ORs) with 95% confidence intervals (CIs). Compared with CCRT, CCT after CCRT was not associated with statistically significant differences in OS (OR=1.24; 95% CI: 0.89-1.72; P=0.21) or PFS (OR=1.16; 95% CI: 0.74-1.83; P=0.53), but increased the risk of toxicity, including infection (P=0.02), pneumonitis (P=0.003) and treatment-related death (P=0.04). There were no significant differences in terms of benefit according to particular patient characteristics, such as age, gender, performance status, tumor histology or clinical stage. Thus, the present study failed to support the use of CCT after CCRT over CCRT alone, as there was no significant OS and PFS benefit for LA-NSCLC patients, but the use of CCT after CCRT resulted in increased toxicity.

Abstract
Background To investigate the efficacy, safety, and tolerability of weekly docetaxel treatment in advanced non‐small cell lung cancer (NSCLC) patients in Korea. Methods This prospective observational study included Korean advanced NSCLC patients with Eastern Cooperative Oncology Group performance status <2 who received weekly monotherapy of docetaxel at a dose determined by the physician. Efficacy measurements included tumor response rate, overall survival (OS), progression‐free survival, and one‐year survival rate. Safety was analyzed through recorded incidences of adverse events (AEs), serious adverse events (SAEs), deaths, and other related safety parameters, along with their toxicity grades. Results: Of 274 patients analyzed, one patient achieved a complete response and 42 partial responses; thus, the overall response rate was 15.7%. The OS rate at baseline and at one‐year follow‐up was 38.3% and 33.8%, respectively. AEs were reported in 229 (83.6%) patients. The most frequently reported hematologic AE of grade ≥3 was a decrease in neutrophils, with 6.6% of the patients developing neutropenia. In non‐hematologic AEs of grade ≥3, the most common were infection with unknown absolute neutrophil count and death not associated with Common Terminology Criteria for Adverse Events (CTCAE) (4.7% each). The most common SAE reported was death, not associated with CTCAE (7.3%). Conclusions In Korean patients, the weekly regimen of docetaxel monotherapy was safe and efficacious against advanced NSCLC.

Abstract
BACKGROUND Lung cancer is the second most diagnosed cancer in the UK. Over 70% of lung cancers are non-small cell lung cancers (NSCLCs). Patients with stage III or IV NSCLC may be offered treatment to improve survival, disease control and quality of life. One-third of these patients receive further treatment following disease progression; these treatments are the focus of this systematic review. OBJECTIVES To appraise the clinical effectiveness and cost-effectiveness of erlotinib [Tarceva(®), Roche (UK) Ltd] and gefitinib (IRESSA(®), AstraZeneca) compared with each other, docetaxel or best supportive care (BSC) for the treatment of NSCLC after disease progression following prior chemotherapy. The effectiveness of treatment with gefitinib was considered only for patients with epidermal growth factor mutation-positive (EGFR M+) disease. DATA SOURCES Four electronic databases (EMBASE, MEDLINE, The Cochrane Library, PubMed) were searched for randomised controlled trials (RCTs) and economic evaluations. Manufacturers' evidence submissions to the National Institute for Health and Care Excellence were also considered. REVIEW METHODS Outcomes for three distinct patient groups based on EGFR mutation status [EGFR M+, epidermal growth factor mutation negative (EGFR M-) and epidermal growth factor mutation status unknown (EGFR unknown)] were considered. Heterogeneity of the data precluded statistical analysis. A de novo economic model was developed to compare treatments (incremental cost per quality-adjusted life-year gained). RESULTS Twelve trials were included in the review. The use of gefitinib was compared with chemotherapy (n = 6) or BSC (n = 1), and the use of erlotinib was compared with chemotherapy (n = 3) or BSC (n = 1). One trial compared the use of gefitinib with the use of erlotinib. No trials included solely EGFR M+ patients; all data were derived from retrospective subgroup analyses from six RCTs [Kim ST, Uhm JE, Lee J, Sun JM, Sohn I, Kim SW, et al. Randomized phase II study of gefitinib versus erlotinib in patients with advanced non-small cell lung cancer who failed previous chemotherapy. Lung Cancer 2012;75:82-8, V-15-32, Tarceva In Treatment of Advanced NSCLC (TITAN), BR.21, IRESSA Survival Evaluation in Lung cancer (ISEL) and IRESSA NSCLC Trial Evaluating REsponse and Survival versus Taxotere (INTEREST)]. These limited data precluded conclusions regarding the clinical effectiveness of any treatment for EGFR M+ patients. For EGFR M- patients, data were derived from the TArceva Italian Lung Optimization tRial (TAILOR) trial and Docetaxel and Erlotinib Lung Cancer Trial (DELTA). Retrospective data were also derived from subgroup analyses of BR.21, Kim et al., TITAN, INTEREST and ISEL. The only statistically significant reported results were for progression-free survival (PFS) for TAILOR and DELTA, and favoured docetaxel over erlotinib [TAILOR hazard ratio (HR) 1.39, 95% confidence interval (CI) 1.06 to 1.82; DELTA HR 1.44, 95% CI 1.08 to 1.92]. In EGFR unknown patients, nine trials (INTEREST, IRESSA as Second-line Therapy in Advanced NSCLC - KoreA, Li, Second-line Indication of Gefitinib in NSCLC, V-15-32, ISEL, DELTA, TITAN and BR.21) reported overall survival data and only one (BR.21) reported a statistically significant result favouring the use of erlotinib over BSC (HR 0.7, 95% CI 0.58 to 0.85). For PFS, BR.21 favoured the use of erlotinib when compared with BSC (HR 0.61, 95% CI 0.51 to 0.74) and the use of gefitinib was favoured when compared with BSC (HR 0.82, 95% CI 0.73 to 0.92) in ISEL. Limitations in the clinical data precluded assessment of cost-effectiveness of treatments for an EGFR M+ population by the Assessment Group (AG). The AG's economic model suggested that for the EGFR M- population, the use of erlotinib was not cost-effective compared with the use of docetaxel and compared with BSC. For EGFR unknown patients, the use of erlotinib was not cost-effective when compared with BSC. CONCLUSIONS/FUTURE WORK The lack of clinical data available for distinct patient populations limited the conclusions of the assessment. Future trials should distinguish between patients with EGFR M+ and EGFR M- disease. FUNDING The National Institute for Health Research Health Technology Assessment programme.

Use of the lung cancer-specific Quality of Life Questionnaire EORTC QLQ-LC13 in clinical trials: A systematic review of the literature 20 years after its development. Cancer 2015; 121:4300-23. [PMID: 26451520 DOI: 10.1002/cncr.29682] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2015] [Revised: 06/24/2015] [Accepted: 07/02/2015] [Indexed: 12/19/2022]
Abstract
The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13) covers 13 typical symptoms of lung cancer patients and was the first module developed in conjunction with the EORTC core quality-of-life (QL) questionnaire. This review investigates how the module has been used and reported in cancer clinical trials in the 20 years since its publication. Thirty-six databases were searched with a prespecified algorithm. This search plus an additional hand search generated 770 hits, 240 of which were clinical studies. Two raters extracted data using a coding scheme. Analyses focused on the randomized controlled trials (RCTs). Of the 240 clinical studies that were identified using the LC13, 109 (45%) were RCTs. More than half of the RCTs were phase 3 trials (n = 58). Twenty RCTs considered QL as the primary endpoint, and 68 considered it as a secondary endpoint. QL results were addressed in the results section of the article (n = 89) or in the abstract (n = 92); and, in half of the articles, QL results were presented in the form of tables (n = 53) or figures (n = 43). Furthermore, QL results had an impact on the evaluation of the therapy that could be clearly demonstrated in the 47 RCTs that yielded QL differences between treatment and control groups. The EORTC QLQ-LC13 fulfilled its mission to be used as a standard instrument in lung cancer clinical trials. An update of the LC13 is underway to keep up with new therapeutic trends and to ensure optimized and relevant QL assessment in future trials.

A Phase II Study of Weekly Docetaxel as Second-Line Chemotherapy in Patients With Metastatic Urothelial Carcinoma. Clin Genitourin Cancer 2015; 14:76-81.

Abstract
UNLABELLED The present multicenter phase II study evaluated the efficacy and safety of weekly docetaxel as second-line chemotherapy for metastatic urothelial carcinoma. Weekly docetaxel was well tolerated but demonstrated modest activity, with a response rate of 6%, a median progression-free survival (PFS) of 1.4 months, and a median overall survival (OS) of 8.3 months. The dichotomy between PFS and OS was likely associated with subsequent platinum-based chemotherapy received by 58% of the patients. BACKGROUND Docetaxel is commonly used for second-line therapy for metastatic urothelial carcinoma (UC). However, myelosuppression is a substantial concern when the traditional 3-week docetaxel cycle is used. The present multicenter phase II study evaluated the efficacy and safety of weekly docetaxel as second-line chemotherapy for metastatic UC. PATIENTS AND METHODS Patients with progression after previous platinum-based chemotherapy for advanced or metastatic disease were treated with docetaxel 30 mg/m(2) on days 1 and 8 every 21 days. The primary endpoint was the response rate. RESULTS The study enrolled 31 patients. Their median age was 64 years (range, 40-79 years). An Eastern Cooperative Oncology Group performance status of 1, liver metastasis, and a hemoglobin level < 10 g/dL were observed in 100%, 32%, and 23% of patients, respectively. Previous platinum-based chemotherapy had been administered for metastatic disease in 29 patients (94%). Although fatigue (13%) and anorexia (6%) were the most frequently observed grade 3 to 4 toxicities, the safety profiles were generally mild and manageable. Two patients (6%) achieved an objective response, which was maintained for 3.0 to 7.8 months. Eight patients experienced disease stabilization (disease control rate, 32%). The median progression-free survival (PFS) and overall survival (OS) were 1.4 months (95% confidence interval [CI], 1.3-1.6) and 8.3 months (95% CI, 5.9-10.6), respectively. A relatively long OS was associated with further salvage platinum-based chemotherapy (n = 18, 58%) showing an encouraging activity (response rate, 44%; median PFS, 4.0 months). CONCLUSION Second-line chemotherapy with weekly docetaxel was well tolerated but demonstrated modest activity in patients with metastatic UC. A platinum-based combination as second-line treatment might be considered for selected patients.

Abstract
PURPOSE To determine the efficacy of consolidation chemotherapy (CC) with docetaxel and cisplatin (DP) after concurrent chemoradiotherapy (CCRT) with the same agents in locally advanced non-small-cell lung cancer (LA-NSCLC). PATIENT AND METHODS Patients were randomly assigned to either CCRT alone (observation arm) or CCRT followed by CC (consolidation arm). CCRT with docetaxel (20 mg/m(2)) and cisplatin (20 mg/m(2)) was administered every week for 6 weeks with a total dose of 66 Gy of thoracic radiotherapy in 33 fractions. In the consolidation arm, patients were further treated with three cycles of DP (35 mg/m(2) each on days 1 and 8, every 3 weeks). The primary end point was 40% improvement in progression-free survival (PFS) compared with observation. RESULTS From October 2005 to April 2011, 437 patients were randomly assigned. Seventeen patients did not start CCRT as a result of consent withdrawal or ineligibility reasons after random assignment, leaving 420 patients for this analysis (n = 211 for observation; n = 209 for consolidation). Patient characteristics were similar in both arms. In the consolidation arm, 143 patients (68%) received CC, of whom 88 (62%) completed three planned cycles. The median PFS was 8.1 months in the observation arm and 9.1 months in the consolidation arm (hazard ratio, 0.91; 95% CI, 0.73 to 1.12; P = .36). Median overall survival times were 20.6 and 21.8 months in the observation and consolidation arms, respectively (HR, 0.91; 95% CI, 0.72 to 1.25; P = .44). CONCLUSION CC with DP after CCRT with weekly DP in LA-NSCLC failed to further prolong PFS. CCRT alone should remain the standard of care.

Pharmacokinetics, dynamics and toxicity of docetaxel: Why the Japanese dose differs from the Western dose. Cancer Sci 2015; 106:497-504.

Abstract
Docetaxel (Taxotere®) has been one of the most important chemotherapeutic drugs for cancer treatment since 1996. Although a large number of clinical studies have been conducted in various cancer fields, there is a discrepancy in the standard dose between Japan and Western countries. This article reviews the pharmacokinetic, pharmacodynamic and toxicological profiles of docetaxel, and explains why there exists an ethnic difference in dose, and further discusses which direction we should go forward to solve this problem. The original recommended dose was 100 mg/m2 every 3 weeks in US and European populations, while a Japanese phase I study suggested the recommended dose as 60 mg/m2 every 3 weeks. A prospective population pharmacokinetic analysis of docetaxel conducted in both the USA/Europe and Japan, indicated an absence of ethnic difference in the pharmacokinetics. Both analyses demonstrated that docetaxel clearance is related to α1-acid glycoprotein level, hepatic function, age and body surface area. The relationship was observed between increasing docetaxel dose and increased tumor response rates across the dose range of 60 to 100 mg/m2. The area under the serum concentration time curve (AUC) of docetaxel at the first cycle was significantly related to time to progression. Hematological toxicities were well correlated with the AUC of docetaxel, and severe hematological toxicities were more frequently observed in Japanese patients treated with 60 mg/m2, compared to the US/European patients treated with 75–100 mg/m2 dose. The Japanese population seems more susceptible to the toxicity of docetaxel. A docetaxel dose of 75 mg/m2 is now standard not only in global trials but also in recent Japanese trials. Although the optimal dose of docetaxel is still unclear, we need to continue to seek the appropriate dose of docetaxel depending on patient status and the goals of chemotherapy.

Abstract
Based on demonstrated favourable risk-benefit profiles, taxanes remain a key component in the first-line standard of care for advanced non-small-cell lung cancer (nsclc) and nsclc subtypes. In 2012, a novel taxane, nab-paclitaxel (Abraxane: Celgene Corporation, Summit, NJ, U.S.A.), was approved, in combination with carboplatin, for the first-line treatment of locally advanced or meta-static nsclc. The approval was granted because of demonstrated improved antitumour activity and tolerability compared with solvent-based paclitaxel-carboplatin in a phase iii trial. This review focuses on the evolution of first-line taxane therapy for advanced nsclc and the new options and advances in taxane therapy that might address unmet needs in advanced nsclc.

Abstract
BACKGROUND Weekly docetaxel demonstrated similar efficacy but better tolerability than standard triweekly docetaxel, and carboplatin was less nephrotoxic, neurotoxic and emetogenic than cisplatin. This study aimed to evaluate the efficacy and safety of weekly docetaxel with carboplatin as first-line chemotherapy for advanced non-small cell lung cancer (NSCLC). METHODS Forty-three Chinese patients have been included. Patients were administered docetaxel at a dose of 35 mg/m(2) on days 1, 8, 15 and carboplatin at an area under the curve (AUC) 5 on day 1 every 28-day cycle (maximum six cycles). RESULTS Of the 43 eligible patients, the assessed overall response rate (RR) was 30.2% with 30.2% partial response (PR) in 13 patients, 48.8% stable disease (SD) in 21 patients and 20.9% progressive disease (PD) in 9 patients. The estimated median progression free survival and median overall survival (OS) time were respectively, 120 days (95% CI: 80-160 days) and 340 days (95% CI: 224-456 days) with the patients surviving of 46.5% (95% CI: 31.6-61.4%) at one year and 20.0% (95% CI: 7.1-33.3%) at two years. The major grade 3/4 hematological toxicities were included leucocytopenia in 6 patients (13.9%) and neutropenia in 8 patients (18.6%). One patient (2.3%) suffered grade 1 febrile neutropenia. All grade of the nonhematological toxicities, such as nausea, vomiting, alopecia and fatigue held the proportion of 48.8% (grade 3/4 4.6%), 27.9%, 55.8% and 53.5% (grade 3/4 9.3%), respectively. CONCLUSIONS The combination of weekly docetaxel and carboplatin showed feasible efficacy with acceptable hematologic toxicities for advanced lung cancer.

Abstract
Differences in survival outcomes with various treatments for advanced non-small cell lung cancer are very modest. Despite this, end points looking at the patients' subjective benefit, such as symptom control, quality of life or clinical benefit, have only been sparsely implemented into clinical trials as primary points of interest. This review focuses on available evidence regarding these patients' subjective end points in recent clinical trials. Compared with best supportive care, chemotherapy offers symptom control, not only in patients with objective response to chemotherapy, but also in a proportion of patients with disease stabilization. However, interpretation of quality-of-life objectives is more difficult, owing to several methodological problems, but improvement in various domains of quality of life is also reported. Different treatment options, such as older platinum-based schedules, modern platinum-based doublets, single-agent treatment with a new drug or nonplatinum-based doublets, are comprehensively reviewed. Future randomized studies should take up the challenge of looking at the patients' benefit as a primary end point.

Treatment of stage IV non-small cell lung cancer: Diagnosis and management of lung cancer, 3rd ed: American College of Chest Physicians evidence-based clinical practice guidelines. Chest 2013; 143:e341S-e368S.

Abstract
BACKGROUND Stage IV non-small cell lung cancer (NSCLC) is a treatable, but not curable, clinical entity in patients given the diagnosis at a time when their performance status (PS) remains good. METHODS A systematic literature review was performed to update the previous edition of the American College of Chest Physicians Lung Cancer Guidelines. RESULTS The use of pemetrexed should be restricted to patients with nonsquamous histology. Similarly, bevacizumab in combination with chemotherapy (and as continuation maintenance) should be restricted to patients with nonsquamous histology and an Eastern Cooperative Oncology Group (ECOG) PS of 0 to 1; however, the data now suggest it is safe to use in those patients with treated and controlled brain metastases. Data at this time are insufficient regarding the safety of bevacizumab in patients receiving therapeutic anticoagulation who have an ECOG PS of 2. The role of cetuximab added to chemotherapy remains uncertain and its routine use cannot be recommended. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors as first-line therapy are the recommended treatment of those patients identified as having an EGFR mutation. The use of maintenance therapy with either pemetrexed or erlotinib should be considered after four cycles of first-line therapy in those patients without evidence of disease progression. The use of second- and third-line therapy in stage IV NSCLC is recommended in those patients retaining a good PS; however, the benefit of therapy beyond the third-line setting has not been demonstrated. In the elderly and in patients with a poor PS, the use of two-drug, platinum-based regimens is preferred. Palliative care should be initiated early in the course of therapy for stage IV NSCLC. CONCLUSIONS Significant advances continue to be made, and the treatment of stage IV NSCLC has become nuanced and specific for particular histologic subtypes and clinical patient characteristics and according to the presence of specific genetic mutations.

Risk factors for metastatic castration-resistant prostate cancer (CRPC) predict long-term treatment with docetaxel. PLoS One 2012; 7:e48186. [PMID: 23118948 PMCID: PMC3484044 DOI: 10.1371/journal.pone.0048186] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2012] [Accepted: 09/21/2012] [Indexed: 11/22/2022] Open
Abstract
Purpose For patients with metastatic castration-resistant prostatic cancer (mCRPC), docetaxel plus prednisone leads to superior survival and a higher response rate compared with mitoxantrone plus prednisone. We analyzed the efficacy of long-term treatment with ≥10 cycles of docetaxel, and validated the risk group classification in predicting overall survival (OS) in Japanese patients with mCRPC. Patients and Methods Fifty-two patients with mCRPC were administered 55 mg/m2 docetaxel and 8 mg dexamethasone, every 3 or 4 weeks, simultaneously with hormonal therapy and daily oral dexamethasone. They were divided into two groups, short-term (9 or fewer cycles) and long-term (10 or more cycles). Four risk factors including the presence of anemia, bone metastases, significant pain and visceral metastases were utilized for the risk group classification. Results Fourteen patients (27%) had an elevation of PSA in spite of docetaxel treatment, while 23 patients (44%) had a decline in PSA level, including 9 patients (17%) whose PSA level declined by ≥50%. The median duration of OS after the initiation of this therapy was 11.2 months in the short-term group and 28.5 months in the long-term group. The good risk group showed a significant difference in OS compared with the intermediate and poor risk groups (P<0.001). The median number of cycles of treatment was 14, 4 and 3 for each risk group, respectively (p<0.01). Conclusions The present study indicated that ≥10 cycles of this docetaxel therapy can significantly prolong survival in Japanese men with CRPC. This risk group classification for men with mCRPC at the initiation of this chemotherapy is useful.

Personalising docetaxel and G-CSF schedules in cancer patients by a clinically validated computational model. Br J Cancer 2012; 107:814-22.

Abstract
Background: This study was aimed to develop a new method for personalising chemotherapeutic and granulocyte colony-stimulating factor (G-CSF) combined schedules, and use it for suggesting efficacious chemotherapy with reduced neutropenia. Methods: Clinical data from 38 docetaxel (Doc)-treated metastatic breast cancer patients were employed for validating a new pharmacokinetic/pharmacodynamics model for Doc, combined with a mathematical model for granulopoiesis. An optimisation procedure was constructed and used for selecting improved treatment schedules. Results: The combined model accurately predicted observed nadir timing (r=0.99), grade 3 or 4 neutropenia (86% success) and neutrophil counts over time in individual patients (r=0.63), and showed robustness to CYP3A-induced variability in Doc clearance. For average patients, the predicted optimal support for the standard chemotherapy regimen, Doc 100 μg m−2 tri-weekly, is G-CSF, 300 μg, Q1D × 3, starting day 7 post-Doc. This regimen largely moderates chemotherapy-induced neutrophil nadir and neutropenia duration. The more intensive Doc dose, 150 mg m−2, is optimally supported by the slightly less cost-effective G-CSF 300 μg, Q1D × 4, 5 days post-Doc. The latter regimen is optimal for borderline patients (2000 neutrophils per μl) under Doc, 100–150 mg m−2 tri-weekly. Conclusions: The new computational method can serve for tailoring efficacious cytotoxic and supportive treatments, minimising side effects to individual patients. Prospective clinical validation is warranted.

Abstract
Lung cancer incidence continues to rise and is the number one cause of cancer death in both men and women worldwide with projected 221,130 new cases and 156,940 deaths in the United States in 2011.1 Non-small cell lung cancer (NSCLC) represents more than 85% of the cases with most patients having either locally advanced or metastatic disease at the time of initial diagnosis, and approximately 60%-70% of them have an adenocarcinoma histologic subtype. In the last three years, we have seen several advances in the management of NSCLC, with several factors playing an important role in the treatment decision making process. Maintenance therapy has been added to the algorithm of NSCLC management and Pemetrexed has been studied as single agent or in combination in this setting with recent studies showing safety and improved progression free survival (PFS) and/or overall survival (OS), still the disease for the most part has a dismal outcome. More research work needs to be done to identify which patients truly benefit from these approaches, and to whom we should offer maintenance or switch maintenance vs. close observation.

Abstract
BACKGROUND Ethnic differences in drug susceptibility and toxicity are a major concern, not only in drug development but also in the clinical setting. We review the toxicity profiles of docetaxel according to dose and ethnicity. METHODS We analyzed phase II and III clinical trials that included a once-every-3-weeks single-agent docetaxel arm. Logistic regression analysis was applied to identify the significant variables affecting the reported incidence of docetaxel-induced severe neutropenia. RESULTS Multivariate logistic regression analysis identified studies conducted in Asia [odds ratio (OR) 19.0; 95% confidence interval (95% CI) 3.64-99.0] and docetaxel dose (OR 1.08; 95% CI 1.03-1.13) as independent variables for the incidence of grade 3/4 neutropenia. CONCLUSIONS There is a significant difference in the incidence of docetaxel-induced severe neutropenia between Asian and non-Asian clinical studies. Physicians and pharmacists should consider ethnic diversity in docetaxel toxicity when interpreting the results of clinical trials.

A multicenter, randomized, phase 2 clinical trial to evaluate the efficacy and safety of combination docetaxel and carboplatin and sequential therapy with docetaxel then carboplatin in patients with recurrent platinum-sensitive ovarian cancer. Cancer 2011; 118:3283-93. [PMID: 22072307 DOI: 10.1002/cncr.26610] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2011] [Revised: 06/20/2011] [Accepted: 07/06/2011] [Indexed: 11/09/2022]
Abstract
BACKGROUND The aim of this randomized clinical trial was to evaluate the efficacy and safety of combination (cDC) and sequential (sDC) weekly docetaxel and carboplatin in women with recurrent platinum-sensitive epithelial ovarian cancer (EOC). METHODS Participants were randomized to either weekly docetaxel 30 mg/m(2) on days 1 and 8 and carboplatin area under the curve (AUC) = 6 on day 1, every 3 weeks or docetaxel 30 mg/m(2) on days 1 and 8, every 3 weeks for 6 cycles followed by carboplatin AUC = 6 on day 1, every 3 weeks for 6 cycles or until disease progression. The primary endpoint was measurable progression-free survival (PFS). RESULTS Between January 2004 and March 2007, 150 participants were enrolled. The response rate was 55.4% and 43.2% for those treated with cDC and sDC, respectively. The median PFS was 13.7 months (95% confidence interval [CI], 9.9-16.8) for cDC and 8.4 months (95% CI, 7.1-11.0) for sDC. On the basis of an exploratory analysis, patients treated with sDC were at a 62% increased risk of disease progression compared to those treated with cDC (hazard ratio = 1.62; 95% CI, 1.08-2.45; P = .02). The median overall survival time was similar in both groups (33.2 and 30.1 months, P = .2). The incidence of grade 2 or 3 neurotoxicity and grade 3 or 4 neutropenia was higher with cDC than with sDC (11.7% vs 8.5%; 36.8% vs 11.3%). The sDC group demonstrated significant improvements in the Functional Assessment for Cancer Therapy-Ovarian, Quality of Life Trial Outcome Index scores compared with the combination cohort (P = .013). CONCLUSIONS Both cDC and sDC regimens have activity in recurrent platinum-sensitive EOC with acceptable toxicity profiles. The cDC regimen may provide a PFS advantage over sDC.

Abstract
PURPOSE To evaluate the clinical literature supporting reduced doses of dexamethasone to prevent taxane hypersensitivity reactions (HSRs), and edema/skin toxicities in respect to docetaxel, when taxanes are given weekly, as opposed to every 3 weeks. DATA SOURCE Clinical literature of human-controlled clinical trials, accessed through MEDLINE and meeting abstract databases (from 1990 to 2010). DATA EXTRACTION The retrieved literature was reviewed to include all human clinical trials that recorded adverse effect information with weekly taxanes utilizing reduced-dose or tapering dexamethasone schemas, either prospectively or retrospectively. DATA SYNTHESIS Prophylaxis for paclitaxel-related HSRs generally includes one or more 20 mg doses of dexamethasone, with histamine-1 and -2 receptor antagonists prior to infusion of paclitaxel. Prophylaxis for docetaxel-related HSRs generally includes dexamethasone beginning 1 day before docetaxel, and continuing twice daily for a total of 3 days. These schedules were designed for taxanes given every 3 weeks, but may lead to steroid-related adverse effects when given weekly with weekly taxane administration. Treatment strategies designed to reduce corticosteroid exposure in patients receiving weekly taxanes have been investigated. CONCLUSIONS Several predication strategies utilizing reduced doses of dexamethasone with weekly taxanes appear to be feasible and safe, and can be considered for patients experiencing, or at high risk for steroid-induced side effects. However, the optimal schedule is not yet determined; larger prospective clinical trials are needed.

Abstract
Lung cancer is the major cause of cancer death in the world. Non Small Cell Lung Cancer (NSCLC) accounts approximately 80-85% of all lung cancer diagnosis; the majority of patients will be diagnosed with non operable, advanced-stage disease. Palliative chemotherapy and/or radiotherapy represent the standard of care of this disease. Platinum based doublets with third generation agents are considered the standard of first line advanced NSCLC treatment. However, data arising from the availability of pemetrexed suggest that histology could play a key role in decision making. Advances in understanding of the molecular pathogenesis of lung cancer have led to the identification of several specific targets such as vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) for therapeutic agents. Bevacizumab is the first recombinant humanized monoclonal antibody (mAb) binding VEGF to demonstrate clinical benefit and a rather survival prolongation in combination with chemotherapy in the treatment of non squamous chemo-naive advanced NSCLC patients. Two types of anti-EGFR targeting agents have reached advanced clinical development: mAbs and small molecule inhibitors of the EGFR tyrosine kinase enzymatic activity (TKIs). Among TKIs gefitinib has been tested in several phase II-III studies showing an improvement in survival and responses in first, second and third line treatment in selected patients with specific clinical and molecular characteristics. Furthermore, erlotinib has showed to significantly improve survival in an unselected population of patients following the failure of one or two chemotherapy regimens. This review will discuss the different therapeutic options for first and second line treatment in the clinical practice.
