Introduction:
Ifosfamide is an alkylating agent, frequently used in the treatment of sarcoma. Major side effects of ifosfamide are classified as nephropathy, neuropathy, and hematologic complications. The aim of present study was to determine the frequency and severity of ifosfamide nephropathy in patients with various types of sarcoma.
Materials And Methods:
Ninety patients (52 males and 38 females) who had received ifosfamide chemotherapy for sarcoma were included in this study. Data on physical examination, laboratory studies, and estimation of glomerular filtration rate were collected. The median duration of follow-up was 6 to 12 months. Records of documented nephropathy were identified in these patients.
Results:
The age range of patients on ifosfamide was 5 to 59 years. Thirty-four of the patients were children and 56 were adults. The most common renal side effects were proteinuria (15.5%), glycosuria (7.8%), elevation of serum creatinine (2.2%), hematuria (14.4%), and combination of proteinuria and glycosuria (5.5%). None of the patients had gross hematuria, but microscopic hematuria was present in 14.4%.
Conclusions:
Ifosfamide nephropathy was seen with different degrees of severity in patients with sarcoma. Monitoring of the side effects of ifosfamide should be revised in different populations.
Insights
Ifosfamide chemotherapy can cause kidney damage (nephropathy) in sarcoma patients. This study found varying degrees of ifosfamide nephropathy, highlighting the need for revised monitoring strategies.
Area of Science:
- Oncology
- Nephrology
- Pharmacology
Background:
- Ifosfamide is a key alkylating agent for sarcoma treatment.
- Major ifosfamide toxicities include nephropathy, neuropathy, and hematologic complications.
- This study focuses on ifosfamide-induced nephropathy in sarcoma patients.
Purpose of the Study:
- To determine the frequency and severity of ifosfamide nephropathy.
- To analyze renal side effects in patients receiving ifosfamide for sarcoma.
Main Methods:
- Ninety sarcoma patients (52 male, 38 female) treated with ifosfamide were analyzed.
- Data included physical exams, lab results, and glomerular filtration rate.
- Follow-up duration ranged from 6 to 12 months.
Main Results:
- Renal side effects observed: proteinuria (15.5%), microscopic hematuria (14.4%), glycosuria (7.8%), and elevated serum creatinine (2.2%).
- A combination of proteinuria and glycosuria occurred in 5.5% of patients.
- No gross hematuria was reported, but microscopic hematuria was present in 14.4%.
Conclusions:
- Ifosfamide nephropathy presents with varying severity in sarcoma patients.
- Current monitoring protocols for ifosfamide side effects may require adjustments for different patient populations.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
