Experience with the treatment of advanced pancreatic cancer in Hungary

In the first phase of this study 34 patients with advanced pancreatic cancer have been treated either with gemcitabine/cisplatin or gemcitabine/5-fluorouracil (5FU)/leucovorin combination. (Gemzar: 900 mg/m2, Cisplatin: 20 mg/m2, 5-FU: 750 mg/m2). Treatments were continued till tumor progression. There was no difference observed between the two protocols in the clinical response rates (PR=65%). On the other hand, a significant difference was found between the two protocols regarding the side effects. In the case of gemcitabine/5-FU neutropenia, thrombocytopenia and anaemia (as well as nausea and vomiting) were much less frequent compared to gemcitabine/cisplatin combination. Based on these data the efficacy of gemcitabine/5-FU combination was evaluated in 99 stage III, T1-4, N1 and stage IV, T1-4, N0-1, M1 pancreatic cancer patients throughout 364 treatment cycles. OR was achieved in 10% while stable disease in 52% of the cases. The average survival period was 8.33 months while the time to progression was 5.75 months. Based on these data we recommend gemcitabine/5-FU/leucovorin combination for the treatment of advanced pancreatic cancer.     

晚期非小细胞肺癌p53 和ERCC1 表达状态与顺铂为主的 联合方案化疗的近期有效率的相关性研究*

目的:研究晚期非小细胞肺癌不同的p53和ERCC1表达状态与基于顺铂为主的姑息化疗近期有效率的相关性。方法:对经顺铂联合多西他赛或顺铂联合吉西他滨治疗的48例晚期非小细胞肺癌患者进行回顾性分析,利用既往免疫组化资料,观察基于顺铂为主的方案近期有效率(RR)的影响因素及化疗不良反应。结果:全组48例患者均完成至少两周期化疗,并行疗效评价。该组患者化疗的近期有效率为28例(58.3%),RR与不同的转移病灶部位(P=0.042)及病灶数目(P=0.034)有显著差异。该类方案的近期有效率与ERCC1状态(P=0.012)密切相关,而与p53表达状态(P=0.401)无关。毒性反应主要是骨髓抑制、脱发及消化道反应等。结论:晚期非小细胞肺癌ERCC1阴性患者较ERCC1阳性患者运用顺铂为主的联合方案化疗的近期有效率较高。ERCC1可能是顺铂疗效预测的敏感因子。p53的表达状态可能不是该类方案的疗效预测因子。

Effectiveness of Gemzar-Cisplatin therapy in stage IIIA-N2, IIIB and IV non-small cell lung cancer

120 chemotherapy naive patients were treated with gemcitabine 1250 mg/m2 iv. days 1 and 8 and cisplatin 70 mg/m2 iv. on day 1 between May 1999 and June 2001. The treatments were administered in 21 cycles. The median age of the patients was 53.1 years, the male/female ratio 65%-35%. Performance status was: WHO 0: 26%, WHO 1: 74%. The staging of patients were: IIIA-N2 23%, IIIB 37%, IV 40%. By histology the tumors were: 53.3% adenocarcinoma, 40% squamous cell carcinoma, 2.5% adenosquamous carcinoma, 0.8% macrocellular carcinoma and 3% non-small cell carcinoma (not categorised). We evaluated 413 cycles of chemotherapy. The median number of cycles was 3.44. The primary endpoint of the study was the median survival and time to progression, and the response rate. The results are the following: RR 40% (PR 37.5%, CR 2.5%), MR 13.3%, SD 25%, PD 22%. The time to progression (TTP) in the SD+MR group: 29.8 weeks, in the RR group: 34.1 weeks, mean of all patients: 28.1 weeks. The survival time was estimated by Kaplan-Meier curves. The median survival (MS) of all treated patients was: 54.9 weeks, in the PD group: 34.4 weeks, in the SD+MR group: 59.1 weeks, in the PR+CR group: 62.1 weeks. Conclusion: gemcitabine and cisplatin combination is a very well tolerated therapeutic regimen in the 1st line treatment of NSCLC. Furthermore, this treatment improves the RR and the survival of the patients as well.     

吉西他滨与吉非替尼联合顺铂治疗西北区非小细胞肺癌患者的疗效分析

目的：比较吉西他滨与吉非替尼联合顺铂治疗非小细胞肺癌的临床有效性及安全性。方法：80例非小细胞肺癌患者根据入院顺序平分为治疗组与对照组各40例,治疗组采用吉西他滨联合顺铂治疗,对照组采用吉非替尼联合顺铂治疗。对比观察两组治疗效果及存活时间。结果：经过治疗后,治疗组无完全缓解患（CR）病例,部分缓解（PR）16例,有效率（RR）40．0％;对照组无完全缓解（CR）病例,部分缓解（PR）8例,有效率（RR）20．0％。治疗组的治疗有效率明显高于对照组,两组差异有显着性意义（P〈0．05）。治疗组1年生存率为50．0％（20／40）,对照组1年生存率为45．0％（18／40）,两组1年生存率比较无统计学差异（P〉005）。治疗组在治疗中有20例患者出现不同程度的不良反应,治疗组出现23例不同程度的不良反应。两组不良反应主要为皮疹、腹泻、转氨酶升高、皮肤水泡等。两组总的不良反应发生率与各个单项不良反应发生率相比无显着性差异,具有可比性（P〉0．05）。结论：吉西他滨联合顺铂治疗非小细胞肺癌的临床有能取得更好的近期治疗效果,同时无明显不良反应,但不会提高1年生存率,值得推广应用。     

Gemcitabine in the first and second-line chemotherapy of advanced non-small cell lung cancer

Aim of this study was to estimate efficacy of gemcitabine in first and the second-line chemotherapy for patients with advanced non-small cell lung cancer (stage III and IV). In first-line chemotherapy, 120 patients were treated with different chemotherapy regimens. Fifty-nine patients were treated with gemcitabine / cisplatin (PG), 41 with cisplatin / etoposide (PE) and 20 with mitomycin / ifosfamide / cisplatin (MIC). Forty patients, unsuccessfully treated with PE and MIC in first-line therapy were treated with PG (24 pts) and with best supportive care (BSC) (16 pts). In first-line therapy PG was superior to PE and MIC protocol (mean survival (MS) 10 vs. 7 vs. 8.5 months). Response rate (RR) for PG in first-line therapy was 46% and 21% in second-line. We showed also significantly better survival in patients treated with PG in second-line chemotherapy comparing to best supportive care (MS 9 vs. 5.5 months). Toxic side effects for combination PG was acceptable. This study confirmed that PG combination is safe and effective as first and second-line chemotherapy for patients with advanced non-small cell lung cancer.     

Endostar Combined with Gemcitabine and Cisplatin Chemotherapy for Patients with Metastatic Nasopharyngeal Carcinoma: an Update

OBJECTIVE: A previous phase-2 trial to assess the addition of Endostar to gemcitabine and cisplatin (GC) chemotherapy showed that it improves prognosis in metastatic nasopharyngeal carcinoma (M-NPC) but the study cohort was small. We wished to update that phase-2 trial by enrolling an additional 44 patients and to assess the benefit of Endostar+GC chemotherapy. METHODS: An analysis of 72 M-NPC patients treated between July 2010 and November 2016 was done. The treatment regimen was a combination of gemcitabine (1,000 mg/m²) on days 1 and 8, cisplatin (80 mg/m²) on day 1, and Endostar (15 mg/day) from day 1 to day 14 of a 21-day cycle for ≥2 cycles. The acute toxic effects and therapeutic efficacy were analyzed. RESULTS: The response rate was 77.8%. The median progression-free and overall survivals were 12 and 19.5 months, respectively. A total of 329 cycles of GC and 288 cycles of Endostar were delivered to 72 patients, with the median number of four (range, 2–10) cycles administered per patient. The main grade-3/4 hematologic toxicities were leukopenia (54.1%) and neutropenia (59.8%). The number of non-hematologic adverse events was minimal. The regimen was well-tolerated. CONCLUSIONS: Endostar+GC chemotherapy is an effective, well-tolerated regimen for M-NPC.

Role of angiotensin II and vasopressin in cisplatin-induced emesis

Cisplatin-containing chemotherapy regimens are known to produce intense nausea and vomiting. Angiotensin II (AII) and vasopressin (AVP) have been shown to have emetic properties. The role of these two peptides on cisplatin-induced vomiting was investigated in beagle dogs. Cisplatin (2 mg/kg, IV over 5 min) produced consistent emesis in all dogs after a mean latency time of 144 +/- 4 min. Serum Angiotensin Converting Enzyme (ACE) and plasma AII levels did not significantly change 3 hr after cisplatin administration (at the time of nausea and emesis) in control animals. AVP levels rose from 0.3 pg/ml to 7.5 pg/ml 3 hrs after cisplatin. Complete inhibition of ACE with enalapril (given at 3 mg/kg p.o., 3 hrs prior to cisplatin) reduced AII levels by 70%, but failed to significantly modify the increase in AVP levels (7.2 +/- 2.2 pg/ml), the latency time to emesis (149 +/- 2 min) and the number of emetic episodes induced by cisplatin. These results suggest that AII does not mediate cisplatin-induced emesis, nor does it mediate the increase in AVP observed at the time of emesis. We propose that AVP may be a good marker for nausea and emesis, and that increases in AVP may be neurally-mediated. The large increase in circulating AVP may represent a desirable water conservation response in anticipation of fluid losses induced by vomiting.     

不同化疗方案联合手术治疗非小细胞肺癌的临床疗效及对患者免疫功能的影响分析

目的:探讨分析不同化疗方案联合手术治疗非小细胞肺癌的临床疗效以及对患者免疫功能的影响。方法:经病理学证实的非小细胞肺癌患者94例,随机数字表法将其分为顺铂组与洛铂组,各47例。2组患者均采取手术治疗,并术前行辅助化疗。其中顺铂组采取紫杉醇+顺铂方案,洛铂组接受紫杉醇+洛铂方案。比较治疗前后2组患者临床疗效及KPS评分,并对Ig A、Ig G、Ig M、CD4+及CD8+指标水平进行分析。结果:洛铂组有效率(CR+PR)为87.2%(41/47),与顺铂组[80.8%(38/47)]差异无统计学意义(P0.05)。洛铂组术后KPS评分及CD4+水平高于顺铂组(P0.05),但CD8+水平低于顺铂组(P0.05),差异有统计学意义;2组患者手术前后Ig A、Ig G及Ig M均无统计学意义(P0.05)。洛铂组毒副反应发生率低于顺铂组(P0.05)。结论:含洛铂术前辅助化疗方案有助于改善非小细胞肺癌患者的免疫功能,降低化疗的毒副反应。

Multicenter Phase II Study Evaluating Two Cycles of Docetaxel,Cisplatin and Cetuximab as Induction Regimen Prior to Surgery in Chemotherapy-Naive Patients with NSCLC Stage IB-IIIA (INN06-Study)

Background

Different strategies for neoadjuvant chemotherapy in patients with early stage NSCLC have already been evaluated. The aim of this study was to evaluate the tolerability and efficacy of a chemoimmunotherapy when limited to two cycles.

Methods

Between 01/2007 and 03/2010 41 patients with primarily resectable NSCLC stage IB to IIIA were included. Treatment consisted of two cycles cisplatin (40 mg/m² d1+2) and docetaxel (75 mg/m² d1) q3 weeks, accompanied by the administration of cetuximab (400 mg/m² d1, then 250 mg weekly). The primary endpoint was radiological response according to RECIST.

Results

40 patients were evaluable for toxicity, 39 for response. The main grade 3/4 toxicities were: neutropenia 25%, leucopenia 11%, febrile neutropenia 6%, nausea 8% and rash 8%. 20 patients achieved a partial response, 17 a stable disease, 2 were not evaluable. 37 patients (95%) underwent surgery and in three of them a complete pathological response was achieved. At a median follow-up of 44.2 months, 41% of the patients had died, median progression-free survival was 22.5 months.

Conclusions

Two cycles of cisplatin/ docetaxel/ cetuximab showed promising efficacy in the neoadjuvant treatment of early-stage NSCLC and rapid operation was possible in 95% of patients. Toxicities were manageable and as expected.

氟西汀联合同步放化疗治疗局部晚期非小细胞肺癌的临床观察

目的：观察氟西汀联合同步放化疗治疗局部晚期非小细胞肺癌（none small cells lung carcinoma,NSCLC）的临床疗效及其安全性。方法：选择2010年10月～2011年4月我院收治的III期不能手术的NSCLC患者47例,根据患者的入院顺序,随机分为两组,同步放化疗组（对照组）22例,接受三维适形或调强放疗：肿瘤处方剂量60~66Gy,常规分割：1．8～2．0Gy／次;放疗期间同步两周期“紫杉醇＋顺铂”方案化疗,放疗后再原方案巩固化疗2--3个周期;氟西汀联合治疗组（实验组）25例,从同步放化疗开始起同时服用氟西汀（20-40mg／day）,持续服药半年。随访至1年,观察和评价两组的疗效以及不良反应的发生情况。结果：对照组与实验组的客观有效率分别为77-3％（17／22）和80％（20／25）（P〉0．05）;1年生存率分别为68．2％（15／22）和80％（20／25）（P〉0．05）;1年局控率分别为45．5％（10／22）和76％（19／25）,差异有统计学意义（P〈0．05）。治疗后,实验组患者CD＋／CD8＋比率由1．34±0．23升至1．58±0．22（P〈0．05）,而汉密尔顿抑郁量表（HAMD）总分由13．4±4．8降至9．6±3（P〈0．05）;全组患者主要不良反应为骨髓抑制、消化道反应、放射性食管炎和放射性肺炎,来发生4级不良反应,两组3级不良反应发生率无明显差异（P〉0．05）。结论：对于不能手术的局部晚期NSCLC患者,在同步放化疗的基础上联合氟西汀治疗可以提高肿瘤的1年局控率,促进抗肿瘤免疫,并缓解患者的抑郁情绪,且不加重不良反应。     

Experience with aprepitant in the prevention of nausea and vomiting caused by highly emetic chemotherapy of lung cancer

Approximately one half of cancer patients experience nausea or vomiting during chemotherapy containing high-dose cisplatin, despite the use of a corticosteroid and 5-hydroxytryptamine(3) (5-HT(3)) receptor antagonists. The addition of aprepitant, a neurokinin 1 receptor antagonist, improves control of emesis by a further 15-20%, and improves late phase symptoms (>24 h after chemotherapy). The cornerstone of standard first line lung cancer chemotherapy is high-dose cisplatin. Our experience with aprepitant in the chemotherapy of 10 lung cancer patients is described, who reported more than one episode of vomiting caused by chemotherapy despite the use of ondansetron previously. Aprepitant prevented acute and late phase oncoming vomiting in all 10 patients and acute and late phase nausea in 9 of the 10 patients. According to our experience on a limited number of patients, aprepitant may be of clinical benefit in the supportive treatment of lung cancer, in achieving better quality of life during chemotherapeutic cycles in these patients.     

Adjuvant Chemotherapy with Docetaxel,Cisplatin, and Continuous-Infusion 5-Fluorouracil for Gastric Cancer: A Phase II Study

PURPOSE: This study evaluated the efficacy and safety of adjuvant chemotherapy with the docetaxel plus cisplatin and 5-fluorouracil (5-FU) (DCF) regimen in patients with gastric cancer. PATIENTS AND METHODS: Thirty-two patients with gastric or gastroesophageal junction cancer were enrolled in this study after undergoing radical resection. The patients received the following chemotherapy: docetaxel (60 mg/m²) on day 1, cisplatin (12 mg/m² per day) on days 1 to 5, and 5-FU (2500 mg/m²) continuous infusion for 120 hours, repeated every 3 weeks for six cycles. The primary end point was disease-free survival (DFS). RESULTS: The median DFS was 17.0 months. The 1-year DFS was 72%, and the 2-year DFS was 37.5%. The median overall survival was 28.0 months. Using univariate analysis, the technique of lymph node dissection was a predictor for postoperative relapse. The median DFS was 15.0 months in the D1 group and 18.0 months in the D2 group (P = .043). The most frequent grade 3/4 adverse events were neutropenia (56.25%), diarrhea (9.38%), nausea (6.25%), and vomiting (6.25%); 12.5% of patients developed febrile neutropenia. There were no chemotherapy-related deaths. CONCLUSIONS: The modified DCF regimen is an effective adjuvant chemotherapy in gastric cancer. Hematologic toxicity was frequent but manageable. This regimen merits further investigation.

The role of neoadjuvant and adjuvant chemotherapy regimens consisting of different combinations of drugs in the treatment of advanced oral cancer

We performed a retrospective analysis on the effect of neoadjuvant chemotherapy with three cycles of methotrexate (100 mg/m² on day 1), cisplatin (90 mg/m² on day 1) and bleomycin (20 mg/m² on day 1–5) with 21 d gap between each cycle in 44 patients with advanced squamous cell carcinoma of the cheek, lip and tongue followed by surgery and adjuvant chemotherapy consisting of cisplatin (90 mg/m² on day 1), Mitomycin C (6 mg/m² on day 1) and 5-fluorouracil (1000 mg/m² 120 h continuous infusion from day 1) repeated every 3 weeks for three cycles. Following induction chemotherapy, complete response was observed in 11 out of 44 patients (25%), and a partial response in a further 28 patients (64%). The overall median survival of all patients was 29 months and those in stage III and stage IV were 30 and 15 months respectively (P<0.001). The median duration of the time to relapse in patients who responded to adjuvant chemotherapy was 28 months. The main toxic effect was vomiting followed by hematological toxicity. No treatment-related deaths occurred. The regimen showed a significant response, encouraging median survival and a good tolerability profile.
