Oxaliplatin-induced hypersensitivity reaction: underlying mechanisms and management

High-dose oxaliplatin induces severe hypersensitivity reactions and high recurrence rates during rechallenge in patients treated with hepatic arterial infusion chemotherapy

AIM

To analyze the risk factors for oxaliplatin (OXA)-induced severe hypersensitivity reactions and identify the recurrence rate of the reactions after an OXA rechallenge in patients treated with hepatic arterial infusion chemotherapy (HAIC).

METHODS

Among the 2251 patients treated with HAIC (OXA), 84 patients with gastrointestinal cancer who displayed hypersensitivity reactions between May 2013 and May 2022 were included in this study. Among the 84 patients, 23 (27.4%) developed severe anaphylactic reactions (grade III/IV), and 61 (72.6%) developed grade I/II reactions. We explored the risk factors for severe OXA-induced hypersensitivity reactions. Twenty-seven patients with grade I/II reactions underwent retreatment (HAIC with OXA), and the recurrence rate of the hypersensitivity reactions was determined. A multivariate logistic regression model was used to analyze the risk factors for OXA-induced hypersensitivity reaction.

RESULTS

In the study, multivariate analysis indicated that the dose of OXA (odds ratio [OR] 3.077, 95 % confidence interval [CI] 1.106-8.558, p = 0.031) was an independent risk factor for OXA-induced severe hypersensitivity reactions. Twenty-seven patients with non-severe hypersensitivity reactions underwent retreatment HAIC with OXA and 14 (51.9 %) experienced HSR recurrence, including 2 (7.4 %) who experienced hypersensitivity shock.

CONCLUSIONS

The administration of OXA doses is a risk factor for OXA-induced severe hypersensitivity reactions in patients treated with HAIC (OXA). Rechallenging HAIC with OXA appears to be associated with a higher recurrence rate of the HSR.

Active surveillance and clinical analysis of anaphylaxis based on the China Hospital Pharmacovigilance System

Objective: This study aimed to develop active surveillance programs (ASPs) for anaphylaxis using the China Hospital Pharmacovigilance System (CHPS) and analyze the characteristics, allergens, and management strategies for anaphylaxis within a tertiary hospital setting in China. Methods: We retrospectively analyzed the anaphylaxis cases reported to the National Adverse Drug Reaction Monitoring System in our hospital from 2014 to 2021. Characteristic medical orders, progress notes, and diagnoses in these cases were recorded to identify initial anaphylaxis trigger entries. Based on these initial entries, the questionnaire was developed, and the Delphi method was used to establish consensus entries for anaphylaxis triggers. The CHPS was used to program these trigger entries and construct ASPs, which were then tested on the 238,194 discharged patients to evaluate their performance and analyze the related clinical data. Results: Ten anaphylaxis triggers and three ASPs were ultimately identified. The ASPs captured 309 cases, out of which 94 cases were confirmed as anaphylaxis following manual screening. After removing duplicates, we noted 76 patients who experienced anaphylaxis 79 times. The positive rate of triggers and the positive predictive value of the programs were 0.13% and 30.42%, respectively. The incidence of anaphylaxis in our study was 0.03%, and the number of anaphylaxis cases detected by the ASPs was 5.64 times higher than those detected by the spontaneous reporting system. Anaphylaxis was more common among female patients. Antibacterial drugs, antineoplastic drugs, and contrast media were the most prevalent allergens in clinical practice. Anaphylaxis to antineoplastic drugs had the highest incidence (0.6%) when compared with patients admitted during the same period. Our study revealed a significant underuse of epinephrine and overuse of second-line therapy (glucocorticoids and antihistamines) in the management of anaphylaxis. Furthermore, we found the use and dosage of epinephrine to be inappropriate. Conclusion: The CHPS can effectively utilize both structured and unstructured data to construct anaphylaxis ASPs, and this could counteract the under-reporting by the spontaneous reporting system, the primary adverse reaction monitoring method in China. The treatment and management of anaphylaxis are currently inadequate and require improvement to reduce mortality risk.

Oxaliplatin-Related Hypersensitivity Reactions: A Single Institution Series and Literature Review

Oxaliplatin-based chemotherapy is extensively used for the treatment of gastrointestinal tumors and other malignancies. Oxaliplatin-related hypersensitivity reactions (HSRs) are common during antitumor treatment. Several studies have been conducted to identify predictive risk factors for oxaliplatin-related HSRs, but findings remain controversial. No definitive approach has been identified to reduce the risk of developing HSRs. The aim of this article is to provide an overview of oxaliplatin-related HSRs, and to report our institution's experience. With our work, we reviewed available data from the literature and described our case series. A total of 153 patients were treated with oxaliplatin and 17 developed an HSR. On the whole, 70.6% of reactions were Grade 3, mostly with respiratory and cutaneous symptoms. Steroids and antihistamines were administered to reduce hypersensitivity symptoms and prevent further reactions. A stronger premedication and prolonged time of infusion resulted in milder reactions or absence of subsequent reactions. We did not find any clear predictive factor for the development of HSRs. Although it is not possible to cancel the risk of oxaliplatin-based HSRs, strategies to reduce the risk of occurrence could be stronger premedication and prolonged time of infusion.

Attention and Intervention of Oncologists on Oxaliplatin-induced Adverse Reactions in Mainland China: A Cross-sectional Internet-based Survey

OBJECTIVE

This cross-sectional study aimed to investigate the current attention and intervention of oncologists on oxaliplatin (OXA)-induced adverse reactions (ADRs).

METHODS

In 31 provinces or administrative regions across China, 401 oncologists were surveyed through a self-designed questionnaire. The survey queried the basic information of respondents, clinical use of OXA, OXA-induced ADRs, and relative interventions. Chi-square tests and multiple logistic regression were used to explore the sociodemographic factors influencing the safety perception of OXA and the relevant interventions.

RESULTS

The survey showed that the age of respondents was mainly distributed between 30 and 40 years and the working period for most oncologists was no more than 5 years. Oncologists with long working years were more willing to conduct patient education and inquire about ADRs than those with short working years. The rate of ADRs reported by oncologists with intermediate professional titles was significantly higher than that reported by oncologists with junior and senior professional titles.

CONCLUSION

Our findings indicate that oncologists in mainland China are concerned about OXA-induced ADRs, but the reporting of ADRs still needs to be strengthened. Therefore, training and educational programs are urgently needed to improve the risk management of OXA-induced ADRs among oncologists.

Meta-analysis of risk factors associated with oxaliplatin hypersensitivity reactions in cancer patients

This study aimed to investigate risk factors associated with oxaliplatin hypersensitivity reactions in cancer patients through a meta-analysis. A comprehensive retrieve of Chinese databases China National Knowledge Infrastructure, Wanfang Data, VIP Database and English databases PubMed, ScienceDirect, Embase and Cochrane library was conducted. The studies that meet the requirements for meta-analysis according to inclusion and exclusion criteria were screened and assessed for eligibility. Odds ratio (OR) / Weighted mean difference (WMD) and 95% confidence intervals (95% CIs) or calculable dichotomous and continuous raw data were extracted to perform meta-analysis using random effect model or fixed effect model on the basis of heterogeneity between studies through Review Manager 5.4 software. A total of 14 cross-sectional studies and 3367 cancer patients were included. Meta-analysis results showed that platinum exposure history (OR value 3.13, 95% CI 2.19-4.48, heterogeneity P = 0.26), allergy history (OR value 1.76, 95% CI 1.09-2.85, heterogeneity P = 0.61), platinum free interval (OR value 3.75, 95% CI 2.00-7.06, heterogeneity P = 0.83), dexamethasone premedication dose (OR value 0.28, 95% CI 0.13-0.58, heterogeneity P = 0.21) were significantly correlated to oxaliplatin hypersensitivity reactions. Gender, age, metastasis, combination with bevacizumab, XELOX regimen and cancer types were detected to have no statistically significant effect on oxaliplatin hypersensitivity reactions. Platinum exposure history, allergy history and long platinum-free interval are risk factors of oxaliplatin hypersensitivity reactions. High dexamethasone premedication dose is a protective factor of oxaliplatin hypersensitivity reactions.

Safety Profile of Oxaliplatin in 3,687 Patients With Cancer in China: A Post-Marketing Surveillance Study

Background

Oxaliplatin (OXA), a third-generation platinum derivative, has become one of the main chemotherapeutic drugs for colorectal cancer and other cancers, but reports of adverse reactions are also increasing with the extensive application of OXA. In this study, post-marketing surveillance was carried out to investigate the safety profile of OXA in a real-world setting in Chinese cancer patients to provide a reference for the rational application of OXA.

Methods

All patients with cancer who received OXA-based chemotherapy in 10 tertiary hospitals in Hubei Province, China, between May 2016 and November 2016 were enrolled. A central registration method was used to document patients' demographics, clinical use, and any incidence of adverse reactions to OXA. All adverse drug reactions (ADRs) were collected and analyzed to assess causality, severity, treatment, and outcome.

Results

In total, 3687 patients were enrolled in this study. Approximately 64.6% of the patients were male, and 68.8% were aged 50-70 years, with a mean age of 55.3 years. The proportions of patients diagnosed with colorectal and gastric cancers were 59.3% and 31.6%, respectively. In this study, the overall incidence of ADRs and serious ADRs was 42.7% and 1.3%, respectively. The most common ADRs were gastrointestinal disorders (25.7%), blood disorders (21.1%), and peripheral nervous system disorders (8.0%). The serious ADRs identified were hypersensitivity reactions, thrombocytopenia, abnormal hepatic function, and leukopenia/neutropenia. The median onset of gastrointestinal toxicity, myelosuppression, peripheral neurotoxicity, and abnormal hepatic function was 1 d, 5 d, 1 d, and 14 d, respectively. The majority (84.7%) of hypersensitivity reactions were mild to moderate, and the median time to onset of these reactions was within the first 20 min of OXA infusion. Almost 88.0% of patients who experienced ADRs recovered or improved with treatment.

Conclusion

Our data suggest that OXA-induced ADRs are very common in Chinese patients with cancer; however, more attention should be paid to hypersensitivity reactions caused by OXA. This study provides a valuable reference regarding the safe application of OXA in a real-world setting.

Clinical Features of Oxaliplatin-induced Hypersensitivity Reactions in Chinese Patients: A Retrospective Multicenter Analysis

OBJECTIVE

The characteristics of oxaliplatin-induced hypersensitivity reactions (HSRs) in Chinese patients were investigated to provide a reference for patients treated with oxaliplatin.

METHODS

The study reviewed the records of patients who developed oxaliplatin-induced HSRs in 17 hospitals from May 2016 to May 2017. We collected and analyzed the basic information, history of oxaliplatin administration and premedication treatments, chemotherapy cycles, HSR symptoms, and the management and outcomes of these patients.

RESULTS

Oxaliplatin-induced HSRs were recorded in 137 patients who had been treated with oxaliplatin-containing regimens. Five different chemotherapy regimens were applied. The median infusion cycle when oxaliplatin-induced HSRs occurred was 7, and HSRs occurred during or shortly after oxaliplatin infusion. Most of the patients experienced grade 1 or grade 2 HSRs with mild symptoms of pruritis (49.64%), flushing (46.72%), chest discomfort (26.28%), and urticaria (25.55%). The majority of the patients completely recovered from HSRs following treatment with antihistamines and dexamethasone. Seven patients completed chemotherapy with oxaliplatin after the symptoms resolved with proper management.

CONCLUSION

The results indicate that oxaliplatin-induced HSRs remain an important issue in safely and successfully fulfilling oxaliplatin-containing chemotherapy. Further studies are needed to analyze the risk factors and establish prophylaxis for such reactions.

Oxaliplatin-induced hepatic sinusoidal obstruction syndrome

Oxaliplatin (OXA) is a third-generation platinum anticancer drug that is mainly used for the treatment of metastatic colorectal cancer (CRC). Of note, hepatic sinusoidal obstruction syndrome (HSOS) induced by OXA has become a key concern for patients with CRC receiving chemotherapy with OXA in recent years. Splenomegaly, thrombocytopenia, abnormal liver function, and portal hypertension are some of the main clinical characteristics seen in patients with OXA-induced HSOS. Previous studies have suggested that oxidative stress, inflammatory damage, liver fibrosis, and platelet aggregation and adhesion may be involved in the pathogenesis of OXA-induced HSOS. Currently, there are no specific drugs for prevention and treatment of OXA-induced HSOS. In this review, we summarized the epidemiology, pathological characteristics, clinical predictive indicators, related mechanisms, possible prevention and treatment of OXA-related HSOS.

Successful oxaliplatin desensitization protocol in a patient with colorectal metastatic cancer

INTRODUCTION

Platinum compounds are frequently used for the treatment of colorectal cancer as initial chemotherapy. Oxaliplatin is a third-generation platinum used for the treatment of stage III colorectal cancer and is associated with hypersensitivity reactions. The incidence of hypersensitivity reaction is approximately 12%, with 1-2% of patients developing moderate to severe reactions.

CASE REPORT

A 54-year-old male patient with stage III B colon cancer was diagnosed and chemotherapy with oxaliplatin was indicated by the oncology service. Within 20 min of the first cycle of oxaliplatin, he developed dyspnea, laryngeal spam, foreign body sensation in the throat, nausea, and diarrhea; therefore, the infusion of oxaliplatin was suspended, and intramuscular epinephrine was administered and intravenous hydrocortisone along with chlorpheniramine with adequate resolution of symptoms.Management and outcome: Intradermal skin test performed at the concentration of 5 mg/ml (dilution 1:100) was positive. Due to the symptoms presented we decided to perform desensitization to oxaliplatin (total dose: 250 mg) with three bags-12 steps protocol with an initial concentration dose of 1/100 of the total dose in a course of 5.56 h with no hypersensitivity reactions.

DISCUSSION

Approximately 50% of patients who are exposed to oxaliplatin may have hypersensitivity despite premedication. Desensitization protocol induces tolerance to a drug temporarily and is dependent on continuous exposure.

Oxaliplatin rechallenge in metastatic colorectal cancer patients after prior oxaliplatin treatment

Because the number of cytotoxic agents available for the treatment of metastatic colorectal cancer (mCRC) is limited, rechallenge with the same chemotherapy agents can provide a continuum of treatment. This study investigated the efficacy and feasibility of oxaliplatin rechallenge in mCRC patients who had been previously exposed to oxaliplatin-based chemotherapy. Patients were included if they had mCRC and evaluable disease, had remained disease-free or progression-free for at least 6 months after the last dose of prior oxaliplatin-based therapy, and were retreated with oxaliplatin therapy. Between January 2009 and May 2014, 110 patients were retreated with oxaliplatin-based regimens; of these, 42 (38.2%) had received prior oxaliplatin as adjuvant chemotherapy and 68 (61.8%) as palliative chemotherapy. The overall response rate to oxaliplatin rechallenge was 30.9% (34/110), and the disease control rate was 68.2% (75/110), with one patient achieving complete response, 33 achieving partial response, and 41 having stable disease. Median progression-free survival and overall survival following oxaliplatin rechallenge were 5.9 months (95% confidence interval [CI], 4.4-7.4 months) and 18.5 months (95% CI, 14.0-23.0 months), respectively. Sixteen patients experienced grade 2 or 3 neuropathy. Ten patients experienced any grade hypersensitivity reaction within four cycles of treatment, including six who stopped treatment due to grade 3 or 4 hypersensitivity reactions. Rechallenge with oxaliplatin-based therapy may be an option for patients who achieve at least 6 months of disease-free or progression-free survival with prior oxaliplatin-based chemotherapy. However, neurotoxicity and hypersensitivity reactions should be carefully monitored in this setting.

Comparison between hypersensitivity reactions to cycles of modified FOLFOX6 and XELOX therapies in patients with colorectal cancer

PURPOSE

Although hypersensitivity reactions (HSRs) to oxaliplatin (L-OHP) therapy are well-documented, few reports have compared different therapies in terms of HSR occurrence. In this study, we compared the frequency and pattern of HSRs to modified FOLFOX6 (mFOLFOX6; 5-fluorouracil, levofolinate calcium and L-OHP infusions) and XELOX (capecitabine and L-OHP) therapies, and sought to identify risk factors associated with HSRs.

METHODS

Patients who had received mFOLFOX6 or XELOX chemotherapeutic regimens for unresectable colon or rectal cancer or as adjuvant chemotherapy following colon cancer surgery between April 2012 and August 2015 were included. Potential correlation between treatment modalities (regimen, dosage and route of administration of L-OHP, and injection timing for dexamethasone administration) and HSRs was assessed.

RESULTS

Among the 240 patients included in the study, 136 had received mFOLFOX6 therapy and 104 had received XELOX therapy. Although the frequency of HSRs did not differ between the two groups, incidence of HSRs in the first cycle was higher in the XELOX therapy group. Treatment method or cumulative dosage was not identified as a risk factor for HSR; however, the incidence of ≥grade-2 HSR was higher in cases where the cumulative L-OHP dosage was ≥600 mg/m² and in patients in whom dexamethasone was not co-infused with L-OHP.

CONCLUSION

Although HSR rates were comparable among patients treated with mFOLFOX6 and XELOX, HSRs tended to occur more frequently during the first cycle of XELOX therapy as compared to that with mFOLFOX6 therapy. Our findings warrant careful assessment of ≥grade-2 HSRs in patients who are prescribed cumulative L-OHP dosages of ≥600 mg/m².

Down-Regulating Receptor Interacting Protein Kinase 1 (RIP1) Promotes Oxaliplatin-Induced Tca8113 Cell Apoptosis

Background

Oxaliplatin is a crucial chemotherapy drug that plays an important role in colorectal cancer and oral cancer treatment. However, the molecular mechanism of oxaliplatin in killing tongue squamous cell cancer cells is still unknown. This paper investigates the mechanism of by which oxaliplatin regulates tongue squamous cell carcinoma Tca8113 cell survival and death.

Material/Methods

Tca8113 was treated with 1 μmol/L oxaliplatin for 24 h. Tca8113 cell proliferation and apoptosis were determined by MTT method and flow cytometry, respectively. Western blot was applied to detect receptor-interacting protein kinase 1 (RIP1) level. Tca8113 was transfected with siRNA RIP1 and then treated with 1 μmol/L oxaliplatin, and the cell apoptosis was detected.

Results

We found that 1 μmol/L oxaliplatin could inhibit Tca8113 cell growth (cell survival rate was 19.3%), reduce mitochondrial membrane potential (reduce 82.3%) and phosphatidylserine eversion (positive rate was 62.7%), and activate caspase-3 (increased 2.6 times). We also found that 1 μmol/L oxaliplatin treatment could increase RIP1 expression in Tca8113 cells. Cell apoptosis rate increased after siRNA RIP1 and 1 μmol/L oxaliplatin treatment (apoptosis rate was 90.2%).

Conclusions

Down-regulating RIP1 promotes oxaliplatin induced Tca8113 cells apoptosis.
