The availability of chemotherapeutic drugs administrable by oral route represents a step forward in the management of cancer patients. Among oral agents, vinorelbine is particularly interesting for its pharmacological characteristics and clinical efficacy. Oral vinorelbine is rapidly absorbed (1.5-3 hours) with an elimination half-life of approximately 40 hours. It shows a low level of binding to plasma proteins (13%), is highly bound to platelets (78%) and has a hepatic metabolism and an absolute bioavailability of 40% with a moderate and similar interpatient variability for the two forms. Food has no influence on the pharmacokinetic profile of oral vinorelbine even if nausea/vomiting is less frequent and less severe in the fed patients than in the fasting patients. Therefore, to ensure patient comfort, it is recommended that oral vinorelbine is administered with a snack. All the metabolites of oral vinorelbine have been identified and, among these, only deacetyl-vinorelbine presented activity demonstrating that for both oral and intravenous (i.v.) routes of administration the drug has the same metabolism pattern. Oral vinorelbine is eliminated mainly in a unconjugated form via the bile. In this process, the CYP 3A4 isoform of cytochrome P450 is mostly involved. Absorption of oral vinorelbine is not delayed in elderly patients. After oral administration, blood concentrations of vinorelbine in elderly patients are within the range of values observed in younger patients. The absolute bioavailability is close to 38% in elderly whereas it is close to 40% in younger patients. This difference is not significant. As compared to the intravenous drug, oral vinorelbine demonstrated linear pharmacokinetics as well an absolute bioavailability of approximately 40%, and a reliable dose-correspondence of 80 mg/m2 oral form --> 30 mg/m2 i.v. and 60 mg/m2 oral --> 25 mg/m2 i.v. Therefore, i.v. and oral forms show similar interindividual variability, same metabolism pattern, reproducible intra-patient blood exposure, and same pharmacokinetic-pharmacodynamic relationship. Oral vinorelbine has shown significant activity in advanced non-small cell lung cancer. Given at 60 mg/m2/week for the first 3 administrations and then increased to 80 mg/m2/week achieved the same efficacy as i.v. vinorelbine in terms of progression-free survival, overall survival, objective response. Mild-to-moderate gastrointestinal toxicity, easily manageable with standard treatment was recorded. Reproducible efficacy compared to previously reported results with vinorelbine i.v. Also, in advanced breast cancer, oral vinorelbine has shown significant activity with a good therapeutic index. Albeit no formal comparison between the oral and the intravenous formulations of vinorelbine has been made, however, the oral route seems to offer major advantages to patients who are faced with a clear decrease in the frequency of hospital admissions as compared to that needed to give intravenous chemotherapy.  相似文献

Introduction: Originally formulated as an intravenous (i.v.) agent, vinorelbine is also currently available as an oral chemotherapeutic agent. Oral vinorelbine has demonstrated significant activity in different settings for NSCLC, including adjuvant treatment for resected disease, concurrent chemoradiation for locally advanced NSCLC and palliative chemotherapy for recurrent/metastatic NSCLC, as part of combination schedules or as a single-agent treatment.

Areas covered: The authors explored the available data describing the use of oral vinorelbine in NSCLC. PubMed articles and abstracts presented at international conferences were analysed, and relevant trials were reported and discussed. Specific settings, including the treatment of elderly and unfit patients and metronomic schedules including oral vinorelbine, were evaluated. Available pharmacoeconomic data were also assessed.

Expert opinion: Oral vinorelbine is an appealing agent, particularly as part of combination regimens containing platinum derivatives, although it can have a role as a single-agent treatment as well. Its safety profile is generally favourable and its route of administration is generally preferred by patients receiving chemotherapy. Compared to i.v. vinorelbine and other antineoplastic agents, oral vinorelbine has been reported to be advantageous in terms of cost savings.  相似文献

Non-small cell lung cancer (NSCLC) may be considered typical of advanced age. More than 50% of NSCLC patients are diagnosed at > 65 years of age and approximately one-third of all patients are > 70 years of age. Elderly patients tolerate chemotherapy poorly compared with their younger counterpart because of the progressive reduction of organ function and comorbidities related to age. For this reason, these patients are often not considered eligible for aggressive platinum-based chemotherapy, the standard medical treatment for advanced NSCLC. In clinical practice, single-agent chemotherapy should remain the standard treatment. Feasibility of platinum-based chemotherapy remains an open issue and has to be proven prospectively. Moreover, a multidimensional geriatric assessment for individualised treatment choice in NSCLC elderly patients is mandatory. This review focuses on the currently-available evidences for the treatment of elderly patients affected by advanced NSCLC with regards to the role and safety of platinum-based chemotherapy.  相似文献

生物标志物检测使得许多晚期非小细胞肺癌(NSCLC)患者获益。近年来,针对表皮生长因子受体(EGFR)和间变性淋巴瘤激酶(ALK)突变呈阳性的NSCLC患者,以吉非替尼、厄洛替尼、阿法替尼为代表的表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI)和以克唑替尼为代表的ALK-TKI取得了卓越的疗效。但是,大多数第一代EGFR-TKI和ALK-TKI的疗效因为不可避免的继发性耐药而被减弱。目前,第三代EGFR-TKI正是基于第二代EGFR-TKI的耐药机制研发而成。除此之外,还有许多针对其他突变位点的晚期NSCLC维持治疗的靶向抑制剂。遗憾的是,针对突变比例最大的K-RAS突变,尚无疗效确切的靶向药物。因此,基于肿瘤驱动基因突变机制的探索和靶向药物的开发是目前NSCLC的研究热点。  相似文献

The objective of this study was to assess whether adding cisplatin to gemcitabine/vinorelbine combination improves the clinical outcome in patients with non-small-cell lung cancer (NSCLC). Chemotherapy-na?ve patients with advanced NSCLC; age < or = 75 years: Karnofsky performance status > or = 60%, and with adequate hematological, renal and hepatic function, were randomized into 2 treatment groups to receive Gemcitabine 1250 mg/m2 + vinorelbine 30 mg/m2 (GV group), or cisplatin 50 mg/m2 + gemcitabine 1000 mg/m2 + vinorelbine 25 mg/m2 (CGV group). All drugs were administered on days 1 and 8 every three weeks: From September 1999 to March 2003, 114 patients were enrolled. No statistically significant difference was observed in GV vs CGV group in objective response (37 versus 47%, respectively; P = 0.5), median time to progression (5 versus 5.8 months; P = 0.6), overall survival (9 versus 10 months; P = 0.9) and 1-year survival (26 versus 28%; P = 0.9). Conversely, toxicities were significantly higher for CGV, including grade 3-4 neutropenia (24 versus 45%); neutropenic fever (4 versus 14%, including one toxic death); grade 3-4 thrombocytopenia (2 versus 14%); and grade 3-4 emesis (2 versus 14%). Our results suggest that the combination of gemcitabine and vinorelbine is less toxic than three-drug combination with cisplatin while showing similar efficacy.  相似文献

Introduction: Crizotinib is a first-in-class ALK tyrosine kinase inhibitor (TKI), which has proven its superiority over standard platinum-based chemotherapy for the first-line therapy of ALK-rearranged non-small cell lung cancer (NSCLC) patients. The development of acquired resistance to crizotinib represents an ongoing challenge with the central nervous system being one of the most common sites of relapse. Ceritinib and alectinib are approved second-generation ALK TKIs. Several novel ALK inhibitors, more potent and with different selectivity compared to crizotinib, are currently in development.

Areas covered: This review will focus on new ALK inhibitors, currently in phase 1 or 2 clinical studies. We will also comment on the mechanisms of resistance to ALK inhibition and the strategies to delay or overcome resistance.

Expert opinion: The therapeutic management of ALK-rearranged NSCLC has been greatly improved. Next-generation ALK inhibitors have shown differential potency against ALK rearrangements and ALK resistance mutations. The molecular profile of the tumor at the time of disease progression to crizotinib is crucial for the sequencing of novel ALK TKIs. Ongoing clinical studies will address key issues, including the optimal therapeutic algorithm and whether combinational approaches are more effective than single ALK inhibition for the outcome of ALK-rearranged NSCLC patients.  相似文献

Summary Cisplatin-based chemotherapy is the standard treatment for advanced non-small cell lung cancer (NSCLC). Several platinum-based doublets have been tested in phase II/III trials with equivalent results in terms of tumour response and survival. Our study was designed to evaluate activity, tolerability and convenience of alternating intravenous (i.v.) and oral vinorelbine in combination with cisplatin in advanced NSCLC. Forty chemo-naive patients with stage IV or relapsed unresectable disease and good performance status were enrolled to receive i.v. cisplatin 40 mg/m2 on days 1 and 2 plus i.v. vinorelbine 25 mg/m2 on day 1, every 3 weeks. Oral vinorelbine 60 mg/m2 was given at home on day 5, without checking of blood cell count. A total of 175 treatment cycles were delivered. The overall response rate was 30% (one complete, 11 partial responses). Median time to progression and overall survival were 5 and 10 months, respectively. The main toxicity was haematological, with grade 3–4 neutropenia observed in 75% of patients, without febrile neutropenia. Non-haematological toxicity was mild. This schedule of cisplatin and vinorelbine treatment showed a good toxicity profile and an efficacy similar to other standard regimens. Oral vinorelbine could be administered safely at home on day 5.  相似文献
