Abstract
Introduction
Cisplatin (cis-diaminedichloroplatinum II, CDDP), also known as Peyrone's salt, was discovered as a substance in 1844, 100 years before its first use as a cytostatic drug. Its chemical structure was discovered in 1893 by Alfred Werner. In 1965, one property of the salts resulting from platinum electrolysis was accidentally discovered to inhibit bacterial division without, however, a bactericidal effect, which resulted in the formation of 300 times longer than usual bacterial filaments. It is to be noted that the trans isomer does not maintain these properties. The chemical formula of the active form is the hydrolyzed cis-[PtCl(NH3)2(H2O)]+ (1). It was approved for use in 1978 for testicular cancer; its introduction increased the cure rate from 10 to 85% (2).
According to the Summary of Product Characteristics, the current indications for cisplatin treatment alone or in combination chemotherapy, in curative or palliative treatments are testicular carcinoma, ovarian carcinoma (stages III and IV) and squamous cell epithelium of the head and neck (palliative therapy), sarcomas and lymphomas. Its efficiency has been also observed in cases of lung carcinoma, bladder cancer, cervical tumors (3,4). The dosages may increase up to 120 mg/m2 body surface, with administration cycles every three or four weeks (5).
The mechanism of action is the inhibition of DNA synthesis by creating cross-links between and within the DNA strands (the preferred binding site is N-7 position of guanine and adenosine). To a lesser extent, RNA synthesis and protein synthesis are inhibited. DNA alterations induce cell apoptosis. Immunogenic effects (by increasing the tumor antigenicity) were observed, as well as immunosuppressive and radiosensitizing effects.
Concerning pharmacokinetics, cisplatin binds relatively irreversibly to plasma proteins (over 90%), and the bond amount does not exert antineoplastic effects. There is an initial t½ (by distribution) of 10-60 min and a terminal t½ (by elimination) of 2-5 days. Within five days, no more than 45% of the administered quantity is excreted. Fecal excretion is minimal (6).
The most frequent adverse effects are nephrotoxicity, ototoxicity, neuropathy, spinal toxicity, allergic phenomena, a potential carcinogen (late risk of leukemia). The occurrence of chromosomal aberrations in cultured animal cells has been noted. The drug includes special warnings regarding dose-dependent, cumulative and potentially severe renal toxicity (manifesting in 30-40% of the patients); the nephrotoxic potential is additive with other nephrotoxic agents (for example aminoglycosides, contrast agents and ifosfamide). Cisplatin toxicity is also potentiated by co-administration of diuretics (furosemide) and beta-blockers (propranolol). For this reason, it is not advisable to force diuresis with furosemide during the administration of cisplatin treatment, although higher diuresis has a protective effect. Nephrotoxicity is the dose-limiting effect of cisplatin treatment.
Additionally, nausea and associated emesis potential (an effect that can extend up to 7 days after administration) have been noted. Cisplatin is one of the most emetogenic substances used in oncology.
Other side effects are neurotoxicity and cumulative ototoxicity (also potentiated by other ototoxic substances: furosemide and aminoglycosides). The mechanism of ototoxicity may be related to the non-competitive binding (but potentially reversible) at the level of the mechanosensitive transmembrane transporter Na+/H+ (3); mutagenicity potential and fertility reduction (all chemotherapies carry a restriction of conception during the administration and for 6 months after the end of treatment, for both sexes). It is contraindicated during pregnancy. It is teratogenic and mutagenic for laboratory animals; hyponatremia, hypokalemia, hypomagnesemia and hypocalcemia may occur during cisplatin treatment; cardiac arrhythmias and pyrexia (very common).
Cisplatin exerts influence on other chemotherapies: Paclitaxel clearance is reduced by 33%. Overdose can be lethal, and there is no specific antidote.
Calcitriol appears to potentiate the antiproliferative effect of cisplatin. In addition, cisplatin appears to exert oxidative phosphorylation decoupling effects (7).
With regard to renal toxicity, the kidneys accumulate more cisplatin than other tissues, being the main route of elimination (glomerular filtration and tubular secretion). The concentration achieved in the proximal contorted tube is five times higher than the plasmatic one. This phenomenon probably explains the nephrotoxic characteristics of cisplatin (7).
Current strategies used to prevent nephrotoxicity and acute kidney injury are hydration, magnesium supplementation (8-16 mEq) and mannitol-induced diuresis (osmotic diuresis) (8). The second most important platinum derivative used in oncology is carboplatin, for which nephrotoxicity is not so expressed, although it has the disadvantage of more severe myelosuppression. Moreover, carboplatin has a much higher t½ (30 h), and for similar antitumor effects, dosages are in the ratio of 4:1 (carboplatin:cisplatin).
Acute kidney injury associated with cisplatin administration is more common in men, and it occurs with urinary loss of sodium, magnesium and decreased urine concentration. Organic cation transporter 2 (OCT2) is involved in CDDP nephrotoxicity. Hypomagnesemia increases OCT2 expression in the proximal contort tube and increases CDDP uptake, a reason for additional magnesium intake to prevent toxicity. It has been also found that cimetidine would exert protective effects on CDDP by decreasing the expression of the copper transporter 1 (Ctr-1) (9).
The pathophysiological mechanisms involved in CDDP nephrotoxicity are: tubular toxicity, vascular lesions (vasoconstriction), glomerular lesions andinterstitial injury (secondary to an inflammatory response) (10).
Acute kidney injury is defined as an increase of at least 25% in the creatinine value relative to the baseline value within 30 days of cisplatin administration. A study of 821 adults who survived at least 5 years after treatment with CDDP revealed the presence of acute kidney injury in 31.5% of patients with a median GFR decline estimated at 10 ml/1.73 m2 BSA. GFR decreases at values <29 ml/min were found to occur in only 3% of the patients, without dialysis during follow-up. The incidence of acute kidney injury was double in the segment >66 years of age compared to the segment 45-65 years. Most patients suffered from small, but permanent reductions in estimated GFR (11).
Patients and methods
Patients and treatment
The study was approved by the Oncohelp Clinic Ethics Committee; all 163 patients included in the study have voluntarily agreed to participate and provided written consents. One hundred and sixty-three chemotherapy initiations containing cisplatin in the period December 18, 2018 to February 19, 2020 (107 men and 56 women) with 436 treatment cycles (276 in men and 160 in women) were identified retrospectively in the records of OncoHelp Oncology Center. The mean age of the patients at the initiation of treatment was 56.88 years (55.48 for the subgroup of men and 59.29 for the subgroup of women).
The data were processed after anonymization. We carried out the correlation between the biometric data [height, weight and body mass index (BMI)] and the paraclinical data (complete blood count and blood biochemistry) at the patients' hospital admission and during the chemotherapy administration; their treatment endurance being also tracked (number of chemotherapy cycles per patient).
For data processing, we chose individuals who had undergone at least three cycles of cisplatin treatment (81 cases and 243 administrations). The biometric and biological data from the evaluation for cycle 1 (C1) treatment and the evaluation before C3 treatment (after two administrations) were compared. The glomerular filtration rate was estimated using the Cockcroft-Gault formula (12).
Statistical analysis
For statistical evaluations, P<0.05 was considered a significance threshold upon applying t-test and paired t test (available online https://www.medcalc.org/calc/comparison_of_means.php and https://www.statskingdomrespectively.com/160MeanT2pair.html).
Results
The number of treatment cycles undergoing each patient was found to vary
Some patients ceased the treatment because of various reasons, either due to the disease progression or due to their toxicity intolerance. The average number of treatment cycles was 1.72 for men and 2.85 for women and there was a sharp decrease in patient number from one chemo cycle to another (Table I).
The mean creatinine value at initiation was higher for men and its relative increase until entry into treatment cycle 3 was also higher for men (Table II).
The mean GFR was higher for men at the time of treatment initiation, but renal function suffered less during treatment for female patients (Table III and Fig. 1).
It was observed that young people had the lowest functional renal damage following treatment, while for people >65 years the renal functional loss was significant (Table IV and Fig. 2).

Unexpectedly, overweight patients (BMI between 25 and 30) had the best behavior in terms of renal function (Table V and Fig. 3).

A low value (>18 U/l) for aspartate aminotransferase (AST, enzyme also present in the kidneys) was associated with a higher risk of damage to the renal function (Table VIII).

Significant weight loss and significant hemoglobin loss were often associated with cases of marked decreases in GFR (Table IX).
Discussion
The average number of treatment cycles administered per patient could have been higher in the case of a longer follow-up (some of the treatments initiated were ongoing at the time of data collection), but their proportion was not extremely high given the ratio of the average treatment duration of 8 weeks and the duration of the follow-up of 60 weeks. Conversely, chemotherapy with cisplatin is ‘well known’ for its poor tolerability, being listed among the most emetic chemotherapeutic drugs (13).
Women appeared to be somehow protected from the decline in renal function (cisplatin dosing only takes into account creatinine or GFR as an on-off condition). The decline of GFR was found to be proportional to patient age. Special attention should be paid to the age group over 65 years.
Overweight patients (not obese) had the best GFR behavior for cisplatin aggression. Systematic review performed by other authors for cisplatin dosage revealed actual body weight utilization as most frequent used weight input (14) and this was also the case in our chemotherapy dose calculation.
The association of anemia is a risk factor for a steeper decline of GFR. An MCV in the upper normal area is associated with a lower starting GFR, although it appears to be a renoprotective factor, meaning that the relative GFR loss is less important. Animal models indicated cisplatin-induced anemia as a persistent condition (many weeks) and unaccompanied by expected EPO response (15).
From a statistical point of view, the volume of available patients for whom there were complete data on cycles 1, 2 and 3 of cisplatin administration allowed the following statistical validations through a pair-t-test that shows the levels of significance P<0.05 reached for decreases of GFR from cycle 1 to cycle 3 (evaluations after C1 and C2, before the administration of C3) (P=0.00059, mean variation of GFR =-9 ml/min, standard deviation of variation=22.82, cases=82).
In addition, a value of P=0.00562 was calculated for the decrease of GFR from C1 to C3 in cases over 65 years (P=0.00562, mean variation of GFR=-13 ml/min, standard deviation of variation =18.03, cases=19). Authors investigating elderly and non-elderly patients treated with cisplatin did not demonstrate differences in pharmacokinetics (clearance and volume of distribution) for the age criteria (16).
The t-test performed for the differences observed at C3 reached significance levels P<0.05 for the patients group <50 years old vs. group >65 years [P=0.0011; GFR=118.9 vs. 75.7 ml/min, standard error (STD)=46 vs. 26, N=19 vs. 19].
The patients group with BMI <25 vs. BMI group=25-29 reached statistical significance (P=0.0049; GFR=85.8 vs. 110.1 ml/min, STD=27.3 vs. 35, N=32 vs. 24).
In addition, the female group vs. the male group demonstrated statistical significance (P=0.0453 creatinine=0.749 vs. 0.848 mg/dl, STD=0.16 vs. 0.23, N=28 vs. 54). (NB validation performed for GFR revealed P=0.10).
After two cisplatin administrations (evaluation made before the third administration), the mean relative decrease of GFR was 8% (-9.0 ml/min), that is, from a pre-therapeutic mean of 110.06 ml/min before initiation to 101.02 ml/min before cycle three (average relative decrease of GFR of -9% for men and -5% for women).
Protective factors associated with lower GFR decline were observed in the following categories of patients: Overweight (-3% relative GFR decline), female (-5% relative GFR decline), aged >50 years (-5%), absence of anemia (-6%). Factors associated with higher GFR losses were observed in the following categories of patients: Age >65 years (-15% relative decline in GFR), obesity (-14%), presence of anemia and AST values <18 (-12%), male sex (-9%). The recorded decreases for the GFR were statistically significant for the group as a whole, especially for the patients >65 years. The following factors were correlated with lower GFR: Age >65 years and BMI group <25 for evaluation performed prior to cycle three.
