[Abstract] Objective To study the drug concentration change of chemotherapeutic agents in plasma and tissue after arterial and intravenous injection. Methods Gemcitabine and Cisplatin were injected into the 40 mature nude rats with xenografted tumor. The rats were divided into vein injection group and artery injection group randomly. The rats were given Gemcitabine and Cisplatin respectively. Blood samples were collected at 5, 10, 20, 40, 80, 120, 360, 720 min after injection and the tumor tissue specimens were collected at 10, 40, 120, 720 min after injection. Gemcitabine concentration in plasma and tumor tissues were determined by high performance liquid chromatography (HPLC) method, while Cisplatin was determined by inductively coupled plasma-mass spectrometry (ICP-MS)method. The data were analyzed by the pharmacokinetic program. Results Regular concentration change of the three drugs in plasma and tissues were observed after the intravenous and arterial injection, which met the two-compartment model. The pharmacokinetic parameters of the two drugs after intravenous and arterial injection were different. The peak concentration in plasma of artery injection group [Gemcitabine: (20.84±10.11) μg/mL; Cisplatin: (15.13±7.12) μg/mL] were lower than those of the vein injection group [(Gemcitabine: (28.96±7.02) μg/mL; Cisplatin: (21.64±9.72) μg/mL], the peak concentration in tissues of the arterial injections group [Gemcitabine: (20.18±9.43) μg/mL; Cisplatin: (6.98±0.31) μg/mL] were higher than those of the intravenous injection group [Gemictabine: (18.19±10.30) μg/mL; Cisplation: (3.04±0.11) μg/mL], and area under curve (AUC) value [(Gemcitabine: (2641±411) μg/(min·mL); Cisplatin:(6025±870) μg/(min·mL)], in tissues of the arterial injections group were higher than those of the intravenous injection group [Gemcitabine:(1663±568) μg/(min·mL); Cisplatin: (1780±883) μg/(min·mL)]. Conclusion Intraarterial chemotherapy has advantages to intravenous chemotherapy in gemcitabine and cisplatin. These advantages depend on the drug pharmacological properties.endprint

肺癌在我國居惡性腫瘤死亡的第1位,其發(fā)病率仍逐年上升[1]。肺癌分為非小細胞肺癌(non-small cell lung cancer,NSCLC)和小細胞肺癌(small cell lung cancer,SCLC)。非小細胞肺癌占肺癌總數(shù)的85%,其中肺腺癌占30%~40%[2]。大多數(shù)肺癌患者臨床診斷時往往已屬晚期,喪失了手術(shù)治療時機。因此,在肺癌的治療方案選擇中,化療藥物仍然發(fā)揮著舉足輕重的作用[3]。吉西他濱聯(lián)合順鉑治療肺癌的確切療效在一些中外研究中已得到驗證[4-5],但是兩種藥物不同給藥途徑治療肺癌的療效比較研究卻鮮有報道。本研究通過動物實驗研究吉西他濱及順鉑動脈化療與靜脈化療的藥代動力學(xué)表現(xiàn),比較兩種給藥途徑的藥代動力學(xué)特點,以了解動脈化療是否有其優(yōu)勢。

1.3 方法

1.3.1 細胞培養(yǎng)

將人肺癌A549細胞復(fù)蘇,含10%小牛血清的DMEM培養(yǎng)液培養(yǎng),取生長指數(shù)良好的人肺癌A549細胞,用0.25%胰蛋白酶消化,離心,收集細胞用磷酸鹽緩沖液(PBS)稀釋,濃度調(diào)整為5×106/mL,每只小鼠以0.2 mL接種于右腋皮下,待腫瘤長至體積約為1000 mm3時移植于裸大鼠耳后造模。

1.3.4 藥物濃度測定

1.3.4.1 吉西他濱藥物分析 用高效液相色譜法(惠普1100 HPLC系統(tǒng))測定吉西他濱的血漿藥物濃度。采用惠普 Hypersil ODS分析柱(125 mm×4 mm,5μm)。流動相為水,流速為0.8 mL/min。紫外檢測波長268 nm。測定方法的日間誤差及日內(nèi)誤差均<10%。血漿樣品的處理:血漿0.5 mL,加入0.1 mg/mL吉西他濱(內(nèi)標(biāo))50 μL,以乙酸乙酯進行萃取,吹干氮氣,用水溶解殘留物后進樣測定。組織標(biāo)本的處理:在標(biāo)本組織中分別加入0.1 mg/mL吉西他濱、0.1 mg/mL順鉑各50 μL和水2 mL,剪碎,勻漿30 min,取1 mL均勻血漿液,2000 r/min離心10 min,上清液以乙酸乙酯萃取,其余步驟與血漿樣品處理相同。

1.3.4.2 鉑含量檢測 吸取血漿200 μL,對組織樣本進行稱重,經(jīng)濕法消解后,利用電感耦合等離子體質(zhì)譜法(inductively coupled plasma-mass spectrometry,ICP-MS)進行鉑含量測定,分別以“鉑含量/血漿含量(μg/mL)”、“鉑含量/組織含量(μg/mL)”表示測定結(jié)果。通過以下公式將鉑含量換算為藥物含量,結(jié)果表示為“藥物含量/血漿含量(μg/mL)”、“藥物含量/組織含量(μg/mL)”:順鉑含量=檢測的鉑含量×300.05/195.08。ICP MS檢測大鼠血漿、腫瘤鉑含量的加標(biāo)回收率分別為99.70%和97.30%。endprint

1.4 統(tǒng)計學(xué)方法

采用SPSS 13.0統(tǒng)計學(xué)軟件進行數(shù)據(jù)分析,計量資料數(shù)據(jù)用均數(shù)±標(biāo)準(zhǔn)差(x±s)表示,兩組間比較采用t檢驗,以P < 0.05為差異有統(tǒng)計學(xué)意義。應(yīng)用DAS 2.0軟件進行藥代動力學(xué)分析。

2 結(jié)果

2.1 兩組注射化療藥物后血漿及組織中的濃度變化情況比較

動脈及靜脈組注射兩組藥物后,血漿及組織中的藥物濃度出現(xiàn)規(guī)律性變化。如藥物在血漿中的濃度變化,藥物在組織中的濃度變化也可用數(shù)學(xué)模型來描述。吉西他濱血漿及組織中藥物濃度變化符合藥代動力學(xué)兩室模型,用藥0~40 min后,靜脈組血漿藥物濃度明顯高于動脈組,并且隨著時間延長,兩組間血漿藥物濃度差異漸消失;藥物注射后動脈組及靜脈組的藥物峰濃度分別為(30.84±10.11)μg/mL及(48.96±7.02)μg/mL,兩組比較差異有高度統(tǒng)計學(xué)意義(P < 0.01)。腫瘤組織內(nèi)藥物濃度水平動脈組與靜脈組相似,峰濃度分別為(20.18±9.43)μg/mL和(18.19±10.30)μg/mL,差異有統(tǒng)計學(xué)意義(P < 0.05)。動靜脈組的血漿及組織藥物峰濃度均在注射藥物結(jié)束時出現(xiàn)(圖1A~D)。

2.2 兩組注射化療藥物后在組織和血漿中藥代動力學(xué)參數(shù)比較

兩組注射順鉑后,靜脈組血漿藥物峰濃度明顯高于動脈組,其峰濃度分別為(21.64±9.72)μg/mL和(15.13±7.12)μg/mL,兩組比較差異有高度統(tǒng)計學(xué)意義(P < 0.01)。動脈組用藥后10 min左右還可在血漿中見雙峰現(xiàn)象,第2峰低于第1峰。兩組用藥后組織中藥物峰濃度動脈組明顯高于靜脈組,兩組比較差異有高度統(tǒng)計學(xué)意義(P < 0.01),因順鉑存在組織吸收過程,靜脈組的組織內(nèi)藥物峰濃度出現(xiàn)于用藥后約28 min。見圖1A、C。

2.3 兩組注射化療藥物后的藥代動力學(xué)參數(shù)變化

兩組注射化療藥物后的藥代動力學(xué)參數(shù)有所差異,從表1可以看出,動靜脈組藥物注射后,組織內(nèi)藥時曲線下面積(AUC)值動脈組均大于靜脈組;血漿的AUC值動脈組均小于靜脈組。兩組注射藥物后,組織內(nèi)的藥物消除速率常數(shù)(β)值動脈組明顯低于靜脈組,因藥物在動脈組組織內(nèi)滯留時間延長。

2.4 兩組注射化療藥物后在組織和血漿中峰濃度比值的比較

動脈注射吉西他濱后,藥物在組織與血漿中的峰濃度比值為(0.591±0.106),AUC比值為(4.61±2.07);靜脈注射吉西他濱后,藥物在組織與血漿中的峰濃度比值為(0.412±0.045),AUC比值為(2.31±0.961),動脈組顯著高于靜脈組(P < 0.05)。動脈注射順鉑后,藥物在組織與血漿中的峰濃度比值為(0.463±0.165),AUC比值為(3.58±0.625),靜脈注射順鉑后,藥物在組織與血漿中的峰濃度比值為(0.141±0.062),AUC比值為(2.04±1.66),動脈組顯著高于靜脈組(P < 0.05)。

3 討論

吉西他濱是目前NSCLC治療最有效的第三代化療藥之一。其作用機制是在機體細胞內(nèi)的核苷激酶作用下生成具有活性的二磷酸核苷(dFdCDP)及三磷酸核苷(dFdCTP),具有抑制細胞DNA合成的聯(lián)合作用,從而發(fā)揮抗腫瘤作用,主要影響細胞DNA合成期(S期),阻止細胞從G1期進入S期。順鉑屬細胞周期非特異性抗腫瘤藥,作用機制為可將細胞阻滯于S期,因其與其他抗癌藥物無交叉耐藥性,故常與其他藥物聯(lián)用共同治療腫瘤[5-8]。1998年美國食品藥品監(jiān)督管理局(FDA)根據(jù)相關(guān)臨床試驗結(jié)果,批準(zhǔn)吉西他濱和順鉑聯(lián)合化療作為晚期NSCLC患者一線治療方案。國內(nèi)外多項體內(nèi)外研究證實吉西他濱與順鉑聯(lián)合用藥可明顯提高生存期,緩解全身癥狀及改善生活質(zhì)量,治療NSCLC效果明顯優(yōu)于以往的常規(guī)化療方案[9-12]。

隨著介入放射學(xué)的發(fā)展,經(jīng)支氣管動脈化療目前已成為治療不可切除性中、晚期肺癌的重要手段[13-15]。但肺癌介入治療的化療用藥方案一般為順鉑、絲裂酶素C、5-氟尿嘧啶、表阿霉素等第二代藥物化療方案[15-16]。吉西他濱動脈灌注給藥已經(jīng)廣泛用于肝轉(zhuǎn)移瘤、胰腺癌和膽管腫瘤的介入治療[17-22],但在肺癌的介入治療中鮮有報道。通過對肺癌動物實驗研究吉西他濱動脈用藥與靜脈用藥的藥物代謝動力學(xué)研究尚未見報道。在臨床應(yīng)用中,雖然裸小鼠肺癌模型制作比較成熟,但因其體積小無法行血管造影檢查,不便在血管介入診療領(lǐng)域進行深入研究。其他大型動物卻成瘤困難。本實驗采用A549肺癌細胞株建立裸大鼠耳后移植瘤,建造肺癌模型,成瘤率高,便于動脈插管,它的成功制作有利于肺癌荷瘤動物動脈介入實驗的順利開展。

研究發(fā)現(xiàn)動脈化療與靜脈化療相比有獨特優(yōu)勢[17,23-25]。首先,動脈注射藥物后,靶組織藥物峰濃度較高,滯留時間也較長,有利于其藥效發(fā)揮,并且動脈給藥后血漿藥物峰濃度及AUC值相對較低,可減少化療藥物全身毒性。局部組織滯留化療藥物的能力是動脈給藥的主要優(yōu)勢,而藥物的藥理特性決定化療藥物藥物在組織中的滯留時間。動脈給藥,可使藥物首先從血漿分布至靶組織,再從靶組織進入循環(huán)系統(tǒng),分布到其他組織中去;而對于靜脈注射,化療藥物首先進入循環(huán)系統(tǒng),再分布至靶組織。由于動脈及靜脈注射藥物經(jīng)歷不同代謝過程,其藥代動力學(xué)參數(shù)必然有所差異。本研究發(fā)現(xiàn)動脈或靜脈注藥后,組織及血漿中藥物濃度出現(xiàn)規(guī)律性變化,可以用兩室模型描述其變化過程。另外,本研究也發(fā)現(xiàn)藥物濃度在血漿分布相快速降低的同時,組織藥物濃度也快速下降,這可能是由于血漿藥物濃度下降加速了藥物從組織向血漿中的轉(zhuǎn)運。

吉西他濱和順鉑兩組藥物經(jīng)頸內(nèi)動脈及尾靜脈注射后,血漿及組織中的濃度變化有不同特點。吉西他濱注射后,血漿及組織峰濃度均在注射結(jié)束后出現(xiàn),藥物分配快。順鉑注射后,靜脈組靶組織內(nèi)藥物峰濃度出現(xiàn)于注射后28 min,而動脈組出現(xiàn)于注射完畢時??梢姡樸K靜脈注射后存在較緩慢的組織吸收過程,這可能與順鉑的蛋白結(jié)合率高及結(jié)合力強有關(guān)。動脈注射后,順鉑首先經(jīng)過靶組織,大量游離順鉑快速分布到靶組織中,而靜脈注射后順鉑首先進入全身循環(huán)與血漿蛋白結(jié)合,減緩了順鉑在組織的分布速度,并減少其在組織中分布濃度。組織內(nèi)AUC定義為藥物在組織內(nèi)濃度和時間的乘積,是組織與藥物接觸程度的量化指標(biāo)。藥物在組織內(nèi)的AUC 值與峰濃度可作為藥物對靶組織作用強度的指標(biāo),或作為對全身作用強度的指標(biāo),也可通過比較靶組織與血漿中藥物的AUC 比值及峰濃度反映動靜脈用藥的優(yōu)劣。endprint

動脈及靜脈注射吉西他濱和順鉑較靜脈注射有不同程度的優(yōu)勢。組織內(nèi)藥代動力學(xué)參數(shù)α、β值反映組織內(nèi)藥物向血漿轉(zhuǎn)運的速度,而血漿內(nèi)的α、β值反映藥物從血漿向組織的分布速度及藥物從血漿的消除速度,α、β值與藥物從血漿或組織的排除速度呈正相關(guān)。本研究發(fā)現(xiàn),動脈注射吉西他濱后,組織內(nèi)α、β值均小于血漿α、β值,表明動脈注射優(yōu)勢本質(zhì)上是藥物在組織中的轉(zhuǎn)運速率低于藥物在血漿中的分布及消除速率。動脈注射順鉑后,這種優(yōu)勢體現(xiàn)于有更多游離順鉑進入靶組織中。若將吉西他濱及順鉑聯(lián)合治療可能有藥代動力學(xué)的互補作用。
