如何使用「卡铂剂量计算器(Calvert 公式)」?How do I use the Carboplatin Dose Calculator (Calvert) tool?

在「卡铂剂量计算器(Calvert 公式)」中,填写「GFR 来源」、「目标 AUC(mg/mL·min)」、「GFR(mL/min)」、「年龄(岁)」、「体重」等参数,结果会随输入实时计算并显示在下方。In the Carboplatin Dose Calculator (Calvert): Fill in "GFR source", "Target AUC (mg/mL·min)", "GFR (mL/min)", "Age (years)", "Weight"; results are recalculated instantly as you type.

Calvert 公式是什么?What is the Calvert formula?

总剂量(mg)= 目标 AUC(mg/mL·min)×(GFR + 25),得到的是 mg,不是 mg/m²。卡铂说明书中常用的目标 AUC 为 4–6。Total dose (mg) = target AUC (mg/mL·min) × (GFR + 25). The result is in mg, not mg/m². The carboplatin label describes target AUCs of 4–6 as typical.

为什么 GFR 封顶在 125?Why is GFR capped at 125?

2010 年 FDA 与美国国家癌症研究所(NCI CTEP)提示:用 IDMS 方法测得的肌酐偏低,可能高估 GFR、导致剂量过高。因此当 GFR 是估算值时,Calvert 公式中的 GFR 不应超过 125 mL/min,最大剂量 = AUC × 150(如 AUC 6 → 900 mg,AUC 5 → 750 mg)。实测 GFR 不受此限制。部分指南(如澳大利亚 ADDIKD)另有做法,以本院方案为准。In 2010 the FDA and the US National Cancer Institute (NCI CTEP) warned that lower IDMS creatinine values can overestimate GFR and lead to overdosing. So when GFR is estimated, the GFR used in the Calvert formula should not exceed 125 mL/min, giving a maximum dose of AUC × 150 (e.g. AUC 6 → 900 mg, AUC 5 → 750 mg). A measured GFR is not capped. Some guidelines (e.g. Australia's ADDIKD) differ; follow your institution's protocol.

Cockcroft–Gault 怎么算?How is Cockcroft–Gault calculated?

CrCl(mL/min)=(140 − 年龄)× 体重(kg)÷(72 × 血清肌酐 mg/dL),女性再 × 0.85。本页使用输入的实际体重;肌酐 µmol/L 按 ÷ 88.4 换算为 mg/dL。肥胖或低体重者常改用理想或校正体重,肌酐异常偏低时 NCI 建议把肌酐下限设为 0.6 mg/dL 或封顶 GFR。CrCl (mL/min) = (140 − age) × weight (kg) ÷ (72 × serum creatinine in mg/dL), × 0.85 for women. This page uses the actual weight you enter; creatinine in µmol/L is divided by 88.4 to get mg/dL. For obese or underweight patients, ideal or adjusted weight is often used instead, and for an abnormally low creatinine the NCI suggests a minimum creatinine of 0.6 mg/dL or capping the GFR.

可以用于临床吗?Can I use this clinically?

不可以。本页只用于学习和核对计算,不能替代处方、医嘱或药师审核。No. This page is only for learning and double-checking the arithmetic; it does not replace a prescription, the treating team or a pharmacist's check.

能举个计算实例吗?Can you show a worked example?

例如在「卡铂剂量计算器(Calvert 公式)」中填 GFR 来源 = 估算 GFR(直接输入),目标 AUC(mg/mL·min) = 5,GFR(mL/min) = 75,结果区显示:用于计算的 GFR:75 mL/min;卡铂剂量(Calvert):500 mg;估算 GFR 时的最大剂量(AUC × 150):750 mg;⚠ 仅供学习和核对,不可用于处方;抗肿瘤药剂量必须由肿瘤科医生和药师确定For example, entering GFR source = Estimated GFR (enter it), Target AUC (mg/mL·min) = 5, GFR (mL/min) = 75 in the Carboplatin Dose Calculator (Calvert) gives: GFR used: 75 mL/min; Carboplatin dose (Calvert): 500 mg; Maximum dose with an estimated GFR (AUC × 150): 750 mg; ⚠ For learning and double-checking only — not for prescribing; oncology doses must be set by the oncology team and pharmacist

哪些输入会被检查?Which inputs are validated?

「卡铂剂量计算器(Calvert 公式)」会检查这些输入——「目标 AUC(mg/mL·min)」:必须填写,须大于 0 且不超过 10;「GFR(mL/min)」:必须填写,须大于 0 且不超过 250;「年龄(岁)」:必须填写,须在 18–120 之间;「体重」:必须填写,须大于 0;「血清肌酐」:必须填写,须在 0.1–20 mg/dL(约 9–1768 µmol/L)之间;绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示,不会给出数字。The Carboplatin Dose Calculator (Calvert) checks its inputs — "Target AUC (mg/mL·min)": required, must be more than 0 and at most 10; "GFR (mL/min)": required, must be more than 0 and at most 250; "Age (years)": required, must be 18–120; "Weight": required, must be greater than 0; "Serum creatinine": required, must be 0.1–20 mg/dL (about 9–1768 µmol/L); numbers above 10¹⁵ in absolute value are rejected too.
