吉西他滨为基础的化疗方案治疗进展期胰腺癌的临床研究 总被引:2,自引:0,他引:2
背景与目的:进展期胰腺癌预后差.吉西他滨可以改善胰腺癌患者的生存质量,但吉西他滨联合方案疗效是否优于单药,还存在争议,国内更缺乏相关的临床研究.本研究目的是比较吉西他滨为基础的联合化疗方案与吉西他滨单药治疗进展期胰腺癌的疗效.方法:回顾性分析2000~2005年收治的40例经临床或病理确诊的进展期胰腺癌临床资料,其中吉西他滨单药组15例,吉西他滨剂量为1 000 mg/m2,每周1次,连用7周,休息2周,之后每周1次,连用3周,4周重复;吉西他滨联合治疗组25例,联合化疗方案包括吉西他滨1 000 mg/m2,每周1次,连用2周,分别联合:(1)氟尿嘧啶425~600 mg/m2,静脉滴注或持续静脉泵入,d1-5,3周重复;(2)顺铂60~75 mg/m2,分第1、2天,3周重复;(3)奥沙利铂85~130 mg/m2,d1,3周重复;(4)卡培他滨l000 mg/m2,2次/天,d1-14,3周重复.采用Kaplan-Meier生存曲线分析患者的生存期,并比较两组间的临床受益反应、中位疾病进展时间、中位生存时间和不良反应.结果:吉西他滨联合组与单药组患者的临床受益反应均得到改善(56.0% vs.46.7%),但疾病控制率、中位生存时间、临床受益反应在两组之间差异无统计学意义(P>0.05),不良反应的发生率也相似(P>0.05).对Ⅲ~Ⅳ期患者进行分层分析,发现吉西他滨联合组疾病控制率高于单药组(75.0% vs.45.5%),但无统计学意义(P=0.13).结论:吉西他滨联合方案与单药治疗进展期胰腺癌相比,疗效、临床受益反应、中位生存时间两组相似. 相似文献

Since pancreatic cancers are frequently discovered in an advanced stage, the expectations for chemotherapy are high. However, the response rate to chemotherapy of advanced cancer remains low. In Western countries, gemcitabine (GEM), a newly approved drug in Japan, was reported to be useful in improving symptoms and prolonging survival. In the present study, we compared 13 patients with unresectable advanced pancreatic cancer who were treated with GEM alone and 13 patients with pancreatic cancer treated with 5-fluorouracil/cisplatin (FP) as historical controls, with reference to therapeutic results, adverse reactions, and clinical benefit response. Although the response rate to GEM was low, at 7.7% (1/13), prolonged NC was seen in 76.9% (10/13) of cases, suggesting a contribution to prolonged survival (p = 0.0025). A clinical benefit response was seen in 38.5% (5/13) of the GEM group, as compared with the lower rate of 7.7% (1/13) in the FP group (p = 0.063). Since GEM is convenient to-administer, and does not diminish a patient's QOL, it is considered to be useful as a drug of first choice in the treatment of advanced pancreatic cancer in terms of clinical benefits. 相似文献

BACKGROUND: This phase II study was initiated to determine the activity and toxicity of a combination of gemcitabine (GEM) and cisplatin (CDDP) in patients with pancreatic cancer. PATIENTS AND METHODS: CDDP 35 mg/m(2) was given as a 30-min infusion and GEM 1000 mg/m(2) as a 30-min infusion. Both drugs were administered once weekly for 2 consecutive weeks out of every 3 weeks to chemonaive patients with locally advanced or metastatic pancreatic cancer. RESULTS: Forty-five advanced pancreatic cancer patients received this regimen for a total of 180 cycles of chemotherapy. One complete and four partial responses have been observed for an overall response rate of 9% (95% confidence interval 10% to 11%). Twenty-one patients (46%) had stable disease and 19 progressed on therapy. The median time to progression was 3.6 months, with a median survival of 5.6 months. A clinical benefit was obtained in nine of 37 patients (24%). Side-effects were mainly represented by hematological toxicity. Grade 3/4 WHO toxicities included neutropenia (6% of the patients) and thrombocytopenia (11%). The dose of GEM and CDDP was reduced in 14 patients (31%) and treatment was delayed in 10 patients (22%). CONCLUSIONS: Our results in terms of response rate, clinical benefit and survival do not support an advantage for the combination of GEM and CDDP given by this schedule. 相似文献

The aim of this phase II multicenter trial was to evaluate the activity of a novel combination of gemcitabine (GEM) and epirubicin (EPI) in advanced pancreatic cancer patients. Clinical benefit and response rate were the main efficacy end-points. From December 1997 to October 1999, 30 consecutive patients with measurable advanced pancreatic cancer were enrolled. Gemcitabine was administered intravenously in 30 min at a dose of 800 mg/m2 on days 1, 8, 15 followed by i.v. injection of epirubicin 25 mg/m(2); treatment was repeated every 28 days. With regard to clinical benefit response, 8/21 patients (38%) experienced significant palliation of tumor-related symptoms; the median symptom control time was 25 weeks. No complete responses were recorded while 6 patients achieved a partial remission, for an overall response rate of 20%; 10 patients (30%) had a stable disease and 14 (46%) had progressive disease. The median time to progression was 14 weeks. Median survival was 26 weeks, with 6 patients (20%) having long-term survival at 46 weeks. In general, chemotherapy was well tolerated; 9 patients (30%) suffered from WHO grade 3-4 haematological toxicity and 5 patients (16.6%) suffered from grade 3 non-haematological toxicity. In conclusion, the GEM plus EPI regimen represent a feasible approach for improvement of clinical benefit in advanced pancreatic cancer patients, but confirmatory investigations are required. 相似文献

OBJECTIVE: The purpose of this study was to identify prognostic factors in patients with gemcitabine-refractory pancreatic cancer and to determine criteria for selecting candidates for second-line treatment. METHODS: The records of 74 patients who were treated with gemcitabine (GEM) and followed up until disease progression were reviewed retrospectively. Sixteen clinical variables at the time of disease progression after GEM chemotherapy were chosen for analysis in this study. Univariate and multivariate analyses were conducted to identify prognostic factors associated with survival. RESULTS: At the time of analysis, 71 patients had died because of tumor progression. The overall median survival time was 5.1 months after first-line chemotherapy with GEM was initiated. Median survival time after disease progression was 2.0 months. Three factors, performance status, peritoneal dissemination and C-reactive protein level, were identified as independent prognostic factors in multivariate analysis. Median survival time in the good prognosis group (patients with performance status 0 or 1, no peritoneal dissemination and C-reactive protein <5.0 mg/dl) was 3.4 months. CONCLUSIONS: Performance status, serum level of C-reactive protein and peritoneal dissemination were identified as important prognostic factors in patients with GEM-refractory pancreatic cancer. These factors should be considered in determining the treatment following first-line chemotherapy in patients with advanced pancreatic cancer. 相似文献

Clinical features of long time survivors with unresectable pancreatic cancer treated by gemcitabine alone 总被引:1,自引:0,他引:1
Kobayashi N Fujita K Fujisawa T Takahashi H Fujisawa N Yoneda M Abe Y Inamori M Kawamura H Kirikoshi H Shimamura T Kubota K Sakaguchi T Saito S Nakajima A 《Gan to kagaku ryoho. Cancer & chemotherapy》2006,33(2):207-212
The objective of this study was to clarify the clinical features of long-time survivors with unresectable pancreatic cancer treated by gemcitabine (GEM) alone and to predict survival time after the first course of treatment. Eighteen consecutive patients (median age 65.3 years, range 49-77 years; 12 males, 6 females) with unresectable pancreatic cancer and a baseline Karnofsky's performance state = or >60 were treated with GEM in a dose of 1,000 mg/m(2) weekly x 3 followed by 1 week of rest until progression. The overall response rate was 0% (CR 0, PR 0, SD 11 cases, and PD 5 cases), and the median survival time (MST) was 268 days. We observed a statistically significant difference in the patients with or without liver metastasis at the start of treatment (131.6 vs 324.9 days; p=0.0045). We also evaluated the usefulness of serial CA 19-9 measurements as a biochemical response marker and an outcome prognostic parameter in patients with unresectable pancreatic cancer receiving GEM alone. We classified two subgroups into responders (patients with a decrease of = or >10% of the baseline CA 19-9 level after 4 weeks of chemotherapy) and non-responder (patients with a increase of the baseline CA 19-9 level or with a decrease of <10% of the baseline CA 19-9 level after 4 weeks of chemotherapy). Responder had a significantly better median survival than non-responders (416.6 vs 138.3 days; p=0.009). In conclusion, CA 19-9 serum concentration serves as an early indicator of response to chemotherapy with GEM alone in unresectable pancreatic cancer. 相似文献

Postoperative adjuvant gemcitabine and concurrent radiation after curative resection of pancreatic head carcinoma: a phase II study 总被引:1,自引:0,他引:1
Van Laethem JL Demols A Gay F Closon MT Collette M Polus M Houbiers G Gastelblum P Gelin M Houtte PV Closset J 《International journal of radiation oncology, biology, physics》2003,56(4):974-980
PURPOSE: The addition of radiation to adjuvant 5-fluorouracil for the treatment of pancreatic cancer has not yet shown any definite benefit. Gemcitabine (GEM) has potential activity in advanced pancreatic cancer and is a powerful radiosensitizer. We evaluated the feasibility of postoperative administration of GEM alone, followed by concurrent GEM and irradiation (RT) after curative resection for pancreatic adenocarcinoma. METHODS AND MATERIALS: GEM 1000 mg/m(2) on Days 1 and 8 every 21 days for three courses was given within 8 weeks after surgery and was followed by GEM 300 mg/m(2) weekly +40 Gy in a split course. Twenty-two patients (median age 59 years, range 39-74, Performance Status 0-1) with Stage II and III curatively resected pancreatic head adenocarcinoma were included. RESULTS: For GEM alone, all patients received the three planned courses, with dose reductions in 7 (32%) of 22 patients. All patients, except two, completed full chemoradiation; one received only 20 Gy because of both World Health Organization Grade 4 vomiting and thrombopenia and the other stopped RT after 32 Gy because of early disease progression. No reduction in GEM during RT was necessary; no toxic death was noted; and World Health Organization Grade 3-4 hematologic and nonhematologic toxicities occurred in 8 (36%) and 7 (nausea, vomiting) (32%) of 22 patients respectively. No late toxicity developed. After a median follow-up of 15 months, 11 patients were alive, and 2 patients had died of causes unrelated to their disease or toxicity, The median disease-free survival and overall survival was 6 and 15 months, respectively. CONCLUSION: This adjuvant regimen was well tolerated and can be easily administered after curative surgery for pancreatic cancer. Its intensification with continuous RT is currently being investigated. 相似文献

We analyzed a treatment outcome and the effect of systemic chemotherapy for patient with unresectable gallbladder carcinoma. Sixteen patients were investigated. Gemcitabine (GEM) was administrated for fifteen patients as the first-line chemotherapy. S-1 was administrated for ten patients as the second-line chemotherapy. The response rate and tumor control rate of the first-line GEM were 14.3% and 78.6%, respectively. The median progression free time of the first-line GEM was 6.0 months. The response rate and tumor control rate of the second-line S-1 were respectively 20.0% and 30.0%. The median progression free time of the second-line S-1 was 1.8 months. The median survival time of all cases was 14.9 months. The outcome of systemic chemotherapy for patients with unresectable gallbladder carcinoma in our hospital was feasible compared with past reports. 相似文献

The early diagnosis of pancreatic cancer is difficult because of the lack of specific early symptoms,and surgery with curative intent can be performed in only 20% of patients. Chemotherapy for unresectable pancreatic cancer has been advancing ever since gemcitabine (GEM) was confirmed to provide a survival advantage in patients with advanced pancreatic cancer. For more than 20 years, the standard treatment for locally advanced diseases has been chemoradiotherapy using 5-FU, but more effective chemotherapy regimens are required. New standard treatments for locally advanced pancreatic cancer, including GEM chemotherapy and chemoradiotherapy using new agents, should be investigated. Several randomized clinical trials comparing GEM-based chemotherapy and GEM alone for the treatment of unresectable pancreatic cancer have been conducted, but a new standard chemotherapy regimen superior to GEM alone has not established. In Japan, phase II studies of S-1 or a combination of GEM and S-1 have produced promising survival rates, and a large phase III study using GEM and S-1 is necessary to establish the standard chemotherapy. Furthermore, second-line chemotherapy regimens for use after GEM chemotherapy should be investigated to improve the survival of patients with advanced pancreatic cancer. 相似文献

Colorectal, gastric and pancreatic cancers are major health problems worldwide. Although surgery is a curative option in 50% of patients with colorectal cancer, it is much less effective in gastric cancer (<20% of patients) and virtually ineffective in pancreatic cancer. These three cancer types also respond poorly to chemotherapy. CPT-11 (irinotecan), a novel cytotoxic drug, is now available in many countries as a single agent for second-line therapy in metastatic colorectal cancer. The response rate in the pivotal European study of metastatic colorectal cancer patients was 14%, with a median duration of response of 8.5 months. There was also a high rate of disease stabilisation (44%), with a median duration of 4.8 months. Median survival time was 10.4 months. The dose-limiting toxicities (DLT) for CPT-11 are delayed diarrhoea and neutropenia, both of which are schedule dependent and non-cumulative. These encouraging data in second-line therapy support the further study of CPT-11 as first-line therapy for colorectal cancer in combination with other agents. Four Japanese trials of CPT-11 as first- and/or second-line single-agent therapy for advanced gastric cancer report response rates of 18–43%. The median durations for response and survival time in the late phase II trial were 2.3 months and 5.8 months, respectively. These results are in the range of those reported for sequential high-dose methotrexate and 5-fluorouracil (5-FU)/doxorubicin (FAMTX), etoposide/leucovorin/5-FU (ELF) or cisplatin/5-FU therapy in gastric cancer. Data are currently available from five phase II studies of CPT-11 in advanced pancreatic cancer: four Japanese and one European. The response rates ranged from 9 to 19%. The median duration of survival for all treated patients in the European study was 5.2 months. CPT-11 in combination with 5-FU is currently being investigated in Japan, the U.S.A. and Europe in patients with gastrointestinal tumours. CPT-11 is also being evaluated in combination with each of the following agents: oxaliplatin, docetaxel, raltitrexed, etoposide and mitomycin C. Japanese studies of CPT-11 plus cisplatin in patients with gastric cancer have produced response rates of 48–59%. These encouraging data highlight the potential for CPT-11 in combination therapy for gastrointestinal tumours. 相似文献

Background/Objectives
Gemcitabine (GEM) is a gold-standard chemotherapy agent for advanced pancreatic cancer. Because of the malignant character of the disease, nearly all patients show disease progression despite treatment with GEM-based chemotherapy; therefore, second-line chemotherapy may be beneficial for these patients. We report a retrospective analysis of 5 patients with advanced pancreatic cancer, treated with a paclitaxel-containing regimen as second-, third- or fourth-line chemotherapy after various therapies, such as a GEM-based regimen, S-1 regimen, and chemoradiation. We retrospectively analyzed the efficacy and adverse events, and evaluated the paclitaxel-containing regimens. A review of the literature is also discussed.Results
The median overall survival from the start of salvage therapy was 10.7 months. The disease control rate of the paclitaxel-containing regimen according to RECIST criteria was 60%, including complete response in 0 patients, partial response in 3, and stable disease in 2. Two patients had malignant ascites at the start of this salvage therapy, and in both of them the ascites and clinical complaints improved. Grade 3 and 4 hematological adverse events were observed in 2 patients and 1 patient, respectively.Conclusion
Salvage paclitaxel-based therapy could be beneficial to advanced pancreatic cancer patients who maintain good performance status after several chemotherapy failures.Key words: Pancreatic cancer, Paclitaxel, Chemotherapy, Gemcitabine failure, Second-line therapy 相似文献13.

PURPOSE: To determine the efficacy and tolerability of gemcitabine (GEM)-concurrent chemoradiotherapy (CCRT) vs. 5-fluorouracil (5-FU) CCRT for locally advanced pancreatic cancer. METHODS AND MATERIALS: Thirty-four patients with locally advanced pancreatic cancer were studied. Eighteen patients were randomized to receive GEM CCRT (600 mg/m(2)/wk for 6 weeks) and 16 patients to receive bolus 5-FU CCRT (500 mg/m(2)/d for 3 days repeated every 2 weeks for 6 weeks). All patients were to receive 3D-CRT 50.4-61.2 Gy at 1.8-Gy/d fractions and GEM (1000 mg/m(2) weekly for 3 weeks repeated every 4 weeks) after RT. RESULTS: The median survival and median time to progression were 14.5 months and 7.1 months for the GEM CCRT group and 6.7 months and 2.7 months for the 5-FU CCRT group (p = 0.027 and p = 0.019, respectively). The quality-adjusted life month survival time was 11.2 +/- 0.5 months for GEM CCRT and 6.0 +/- 0.3 months for 5-FU CCRT patients (p <0.001). The response rate was 50% (four complete responses and five partial responses) for GEM CCRT and 13% (two partial responses) for 5-FU CCRT (p = 0.005). Pain control was 39% for GEM CCRT and 6% for 5-FU CCRT (p = 0.043). Grade 3-4 neutropenia (34% vs. 19%), thrombocytopenia (0% vs. 7%), nausea (33% vs. 31%), vomiting (17% vs. 19%), hospitalization days per month of survival (7.4 +/- 1.7 days vs. 8.0 +/- 1.3 days), and full dose of RT received (78% vs. 75%) were not significantly different between the GEM CCRT and 5-FU CCRT patients. CONCLUSION: GEM CCRT appears more effective than 5-FU CCRT for locally advanced pancreatic cancer and has comparable tolerability. 相似文献

Gemcitabine and oxaliplatin (GEMOX) are active as first-line therapy against advanced pancreatic cancer. This study aims to evaluate the activity and tolerability of this combination in patients refractory to standard gemcitabine (GEM). A total of 33 patients (median age of 57) were included with locally advanced and metastatic evaluable diseases, who had progressed during or following GEM therapy. The GEMOX regimen consisted of 1000 mg m(-2) of GEM at a 100-min infusion on day 1, followed on day 2 by 100 mg m(-2) of oxaliplatin at a 2-h infusion; a cycle that was given every 2 weeks. All patients received at least one cycle of GEMOX (median 5; range 1-29). Response by 31 evaluable patients was as follows: PR: 7/31(22.6%), s.d. > or = 8 weeks: 11/31(35.5%), s.d. < 8 weeks: 1/31(3.2%), PD: 12/31(38.7%). Median duration of response and TTP were 4.5 and 4.2 months, respectively. Median survival was 6 months (range 0.5-21). Clinical benefit response was observed in 17/31 patients (54.8%). Grade III/IV non-neurologic toxicities occurred in 12/33 patients (36.3%), and grade I, II, and III neuropathy in 17(51%), 3(9%), and 4(12%) patients, respectively. GEMOX is a well-tolerated, active regimen that may provide a benefit to patients with advanced pancreatic cancer after progression following standard gemcitabine treatment. 相似文献

Introduction.
Targeted biologic agents showed clinically meaningful efficacy as front-line therapy for advanced radioiodine-refractory and medullary thyroid cancer. The clinical benefit of these agents beyond the front line has yet to be established.Methods.
We assessed the clinical benefit of targeted agents in patients with advanced differentiated and medullary thyroid cancer treated at a single academic cancer center. We determined efficacy and compared front-line and second-line benefit using biochemical and anatomic response, time to treatment failure, and progression-free survival (PFS). Statistical differences were assessed by t test and chi-square test. Survival curves were generated by the Kaplan-Meier method. Differences in survival were assessed using the log-rank test, and a p value <.05 was considered significant.Results.
We identified 39 patients with advanced differentiated and medullary thyroid cancer treated with targeted biologic agents. Median age was 56.3 years. Overall, 25 men and 14 women participated. Histology showed 23% medullary and 77% differentiated cancer. Nineteen patients progressed on front-line therapy and subsequently received second-line therapy. Targeted agents conferred clinically meaningful benefit in the second-line setting in terms of biochemical response (13.3%), clinical benefit (83.3%), median time to treatment failure (4.0 months; 95% confidence interval: 2.6–8.2), and median PFS (4.6 months; 95% confidence interval: 3.2–8.2). Second-line benefit (median PFS) was more modest in comparison to the front-line setting in both genders (women: 3 months vs. 12.2 months; men: 6 months vs. 19.7 months), in differentiated cancers (4.1 months vs. 15.7 months), and with vascular targeting agents (4.4 months vs. 20.1 months).Conclusion.
Patients with advanced thyroid cancer derived meaningful clinical benefit from additional therapy with a biologic agent following disease progression on front-line targeted therapy. 相似文献17.
A phase II trial of gemcitabine plus capecitabine for patients with advanced pancreatic adenocarcinoma 总被引:2,自引:2,他引:0

Purpose While gemcitabine (GEM) is widely accepted for the treatment of advanced pancreatic cancer, capecitabine (CAP) has shown single
agent activity and promising efficacy in combination with GEM. This phase II study was conducted to evaluate the efficacy
and toxicity of GEM combined with dose escalated 14-day CAP as first-line chemotherapy for advanced pancreatic cancer. In
addition, we also analyzed the correlation between CA19-9 response and clinical outcomes.
Methods Patients had advanced pancreatic adenocarcinoma, no prior systemic chemotherapy other than that given concurrently with radiation
therapy, at lease one measurable disease, and adequate organ functions. The patients were treated with GEM 1,000 mg/m2 IV on days 1, 8 and CAP 1,000 mg/m2 twice a day PO on days 1–14, in 21-day cycles.
Results The objective RR among 45 patients was 40.0% (95% CI; 25.1–54.9), including 1CR (2.2%). The median TTP and OS were 5.4 months
(95% CI; 1.8–9.0) and 10.4 months (95% CI; 6.2–14.5), respectively. Patients with ≥25% decline of serum CA19-9 had significantly
better outcomes in terms of TTP and OS than those who did not (P < 0.03). The most frequent, grade 3–4, non-hematologic toxicity was hand–foot syndrome (6.7%).
Conclusions The combination of GEM with dose escalated 14-day CAP is well tolerated and offers encouraging activity in the treatment of
advanced pancreatic cancer. In addition, CA19-9 response correlates well with clinical outcomes in this population. 相似文献

A novel biweekly pancreatic cancer treatment schedule with gemcitabine, 5-fluorouracil and folinic acid 总被引:4,自引:0,他引:4
Correale P Messinese S Marsili S Ceciarini F Pozzessere D Petrioli R Sabatino M Cerretani D Pellegrini M Di Palma T Neri A Calvanese A Pinto E Giorgi G Francini G 《British journal of cancer》2003,89(2):239-242
Pancreatic adenocarcinoma is a common disease considered to be poorly responsive to antiblastic treatment. Recent clinical and preclinical results suggest that a combined treatment of gemcitabine (GEM), 5-flurouracil (5-FU) and folinic acid (FA) offers a clinical benefit in patients with advanced pancreas adenocarcinoma. The aim of this phase II clinical trial was to evaluate the antitumour activity and toxicity of a novel biweekly schedule of this combination in patients with pancreatic adenocarcinoma. A total of 42 patients received a 30 min infusion of FA (100 mg m(-2)) and 5-FU (400 mg m(-2)) (FUFA) on days 1-3, and GEM 1000 mg m(-2) on day 1 every 15 days. We observed 13 objective responses (two complete, 11 partial) and 23 stable diseases. The median time to progression was 9.75 months (95% Confidence Interval (CI), 6.88-12.62) and the median overall survival was 13.10 months (95% CI 9.64-16.56). There were seven cases of each grade III gastroenteric and haematological toxicity. The GEM plus FUFA combination appears to be well tolerated and very active in patients with pancreatic carcinoma. 相似文献

The active mutation of epidermal growth factor receptor (EGFR) and clinical characteristics are significant biomarkers for chemotherapy selection in non-small cell lung cancer (NSCLC). Although docetaxel is a key agent in second-line therapy for NSCLC, predictive biomarkers for assessing its efficacy have yet to be determined. To assess the clinical efficacy of docetaxel in second-line therapy for NSCLC according to NSCLC histology and the therapeutic effect of EGFR-tyrosine kinase inhibitors (EGFR-TKIs), we retrospectively reviewed 454 NSCLC patients treated with docetaxel between April 2002 and April 2009. In total, 239 patients with advanced NSCLC treated with docetaxel as second-line therapy following failure of platinum-based chemotherapy were analyzed in this study. A total of 59 (25%) patients had squamous cell carcinoma. The overall response rate and median progression-free survival time in the squamous cell group were significantly inferior to those in the non-squamous cell group (p=0.031 and p=0.005, respectively). Following the failure of docetaxel, 91 non-squamous patients were treated with EGFR-TKIs. The patients that achieved clinical benefit from EGFR-TKIs (n=32) demonstrated a significantly better response rate and longer progression-free survival compared to the other group (p<0.001 and p=0.027, respectively). In the univariate and multivariate analysis, the favorable therapeutic effect of EGFR-TKIs had an independent effect on progression- free survival (HR 1.484, p=0.0464). In conclusion, this retrospective study suggests that non-squamous histology and favorable therapeutic effect from EGFR-TKIs are useful markers for predicting the efficacy of docetaxel in second-line therapy for NSCLC. 相似文献
