Describes how this page is sourced, not how dangerous the drug is. Thinly sourced means fewer of the sourcing signals are met — not that the agent is kidney-safe. A rule-based summary, not a formal certainty appraisal.

A melanoma alkylator that menaces the hepatic endothelium far more than the nephron.

§01

Signature kidney injury

Direct nephrotoxicity is minimal and not well quantified; the notable vascular toxicity is hepatic veno-occlusive disease / sinusoidal obstruction (now recognized as not rare), with renal effects largely secondary to severe systemic illness, hepatic injury or volume loss.Source: Kintzel, Drug Saf 2001

Onset & rechallenge

Time to injuryVariable / unpredictable

Onset is variable, with hepatic veno-occlusive disease typically occurring days to weeks after exposure.

Distilled from: “Variable; hepatic VOD typically days to weeks after exposure.”

§03

Kidney injury

Mechanism of kidney injury

Dacarbazine and its reactive metabolites are selectively toxic to hepatic sinusoidal endothelial cells through a glutathione-dependent mechanism (depletion of endothelial GSH precedes toxicity), the basis of hepatic veno-occlusive disease and, occasionally, fatal hepatic vein thrombotic occlusion. The kidney is not a primary target; any AKI is typically prerenal from vomiting/volume depletion or hepatorenal-type hypoperfusion accompanying severe hepatic injury.

Clinical presentation

When present, prerenal azotemia (elevated BUN:creatinine ratio, low urine sodium) in the setting of nausea/vomiting and volume depletion; in VOD, hepatomegaly, right-upper-quadrant pain, weight gain and hyperbilirubinemia with secondary renal hypoperfusion.

Management

Supportive: rehydration and antiemetics for prerenal AKI; supportive care for VOD. Prerenal injury reverses with restoration of perfusion; severe hepatic vascular toxicity can be fatal.Lesion-level management framework

Risk factors

  • Volume depletion from severe emesis
  • Hepatic veno-occlusive disease / eosinophilia (reported association)
  • Concurrent hepatotoxins/nephrotoxins

Prevention

  • Robust antiemesis and hydration
Anticancer mechanism· how it treats cancer

Imidazole-carboxamide prodrug activated in the liver (CYP-mediated N-demethylation) to a methylating diazonium species that alkylates DNA at O6-guanine. Used for metastatic melanoma, Hodgkin lymphoma (ABVD) and soft-tissue sarcoma.

§04

Clinical depth

Renal dose adjustment

No established renal CrCl dose modification; dacarbazine is partly renally excreted but dose adjustment is driven mainly by hematologic toxicity and hepatic function. Use general caution and maintain hydration in renal impairment.

Dialyzability & ESKD dosing

Short-lived parent prodrug undergoing hepatic activation; not a drug managed by dialysis. ESKD data are minimal.

Differential diagnosis

Renal injury here is almost always prerenal (low FeNa, volume-responsive) or hepatorenal in the setting of VOD - not intrinsic tubular or microangiopathic injury. Recognizing VOD (tender hepatomegaly, weight gain, hyperbilirubinemia) reframes the AKI as a hepatic, not renal, problem.

Monitoring

  • Volume status and antiemetic adequacy each cycle
  • Liver function tests and clinical exam for veno-occlusive disease
  • Serum creatinine if volume-depleted or hepatically ill

Key trials & series

  • ABVD lymphoma and dacarbazine-based melanoma regimens as the principal exposure context
  • Hepatic vascular toxicity (veno-occlusive disease / Budd-Chiari) is the characteristic severe event; renal involvement is secondary

Clinical pearls

  • Dacarbazine's dangerous vascular toxicity is hepatic (VOD), not renal - the kidney suffers only secondarily.
  • Most dacarbazine-associated AKI is simple prerenal azotemia from emesis - hydrate and the creatinine follows.
  • New hepatomegaly, weight gain and jaundice after dacarbazine should trigger a VOD work-up, not a renal biopsy.

Boxed warning

WARNING It is recommended that dacarbazine be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. 1.Hemopoietic depression is the most common toxicity with dacarbazine (see WARNINGS ). 2.Hepatic necrosis has been reported (see WARNINGS ). 3.Studies have demonstrated this agent to have a carcinogenic and teratogenic effect when used in animals. 4.In treatment of each patient, the physician must weigh carefully the possibility of achieving therapeutic benefit against the risk of toxicity.

What gets reported — FAERS

Everything below is FAERS — adverse events someone chose to report, about 7,411 of them for this agent. Nobody counts the patients who were fine, so none of these numbers is an incidence, a risk, or a rate: they describe what gets reported, shaped by a drug's fame, its indication, and who was watching. How these numbers work.

  • Reporting odds ratio (ROR) — is kidney injury named in this agent's reports more often than in every other drug's? Above 1 means yes, disproportionately.
  • Renal phenotypes — the same question asked separately for each kind of kidney injury, so the ratios differ from the overall one and from each other.
  • Outcomes — a share of this agent's own reports, not of patients: how many were filed as involving a death or a hospitalization. Not a case-fatality rate.
FAERS reported renal phenotypes· 3 signals

Only significant signals appear (95% CI lower bound above 1) — a phenotype missing here was tested and did not reach significance, except Prerenal / Hemodynamic AKI, Pseudo-AKI, Renal Cysts, Chronic Interstitial Nephropathy — outside the clinician-reviewed MedDRA term map, never queried — and ATN and AIN, queried but biopsy-bound: real cases are filed as generic “acute kidney injury”, so their absence is not a negative. As of 2026-10-01.
