Hypersensitivity Reaction to Carboplatin during Treatment for Ovarian Cancer: Successful Resolution by Replacement with Cisplatin

Cisplatin may be a Valid Alternative Approach in Ovarian Carcinoma with Carboplatin Hypersensitivity. Report of Three Cases

Platinum-based therapy is considered the standard treatment for patients with advanced ovarian cancer. Carboplatin has a more favorable toxicity profile than cisplatin; however, hypersensitivity reactions to carboplatin have been reported occasionally. We reviewed 112 cases of ovarian cancer treated with carboplatin at our institute to identify the hypersensitivity reactions to this chemotherapeutic agent. Hypersensitivity reactions were documented in nine cases (8%). No deaths occurred, but the reactions were judged severe in three of the 112 patients (2.6%). In our own experience with patients showing idiosyncrasy to carboplatin we observed successful resolution after retreatment with cisplatin. Since patients who relapse after initial treatment with carboplatin often respond to it a second time, it is important to continue this treatment.

Desensitization treatment with cisplatin after carboplatin hypersensitivity reaction in gynecologic cancer

Platinum-based chemotherapy is the standard regimen for the treatment of gynecologic cancers; however, hypersensitivity reactions (HR) to platinum often lead to discontinuation of this effective treatment. Here we performed a desensitization protocol for platinum infusion in 3 patients who required platinum re-administration after developing HR. Two patients (Case 1 and 2) were treated with the desensitization protocol successfully without developing HR during the subsequent 3 courses. Case 3 tolerated desensitization well for 2 courses, but in the 3(rd) course, she developed severe HR immediately after the initiation of cisplatin infusion because the desensitization protocol was unintentionally omitted. These cases show the usefulness and effectiveness of the desensitization protocol for the continuation of platinum treatment in patients who have undergone an extended number of treatments.

The prophylactic conversion to an extended infusion schedule and use of premedication to prevent hypersensitivity reactions in ovarian cancer patients during carboplatin retreatment

OBJECTIVE

Repeated exposure to carboplatin can lead to hypersensitivity reactions during retreatment with carboplatin. This may prevent its further use in platinum-sensitive ovarian cancer patients. At our institution, an increasing proportion of patients are prophylactically converted to an extended schedule of infusion after 8 cycles of carboplatin. We sought to determine whether an incrementally increasing, extended 3-hour infusion of carboplatin with appropriate premedication was associated with a lower rate of hypersensitivity reactions compared to the standard 30-minute schedule in sequentially treated patients.

METHODS

We performed a retrospective electronic medical record review of patients with recurrent ovarian cancer retreated with carboplatin at our institution from January 1998 to December 2008.

RESULTS

Seven hundred and seventy-seven patients with relapsed ovarian, fallopian tube, or primary peritoneal cancer were retreated with carboplatin and met study inclusion criteria. Of these, 117 (17%) developed hypersensitivity reactions during second-line or greater carboplatin-based treatment for recurrent disease. Only 6 (3.4%) of the 174 patients who received the extended schedule developed hypersensitivity reactions (0% grade 4; 50% grade 3) compared to 111 (21%) of 533 patients in the standard schedule group (13% grade 4; 77% grade 3). The first hypersensitivity episode occurred after a median of 16 platinum (carboplatin and cisplatin) treatments in the extended group compared to 9 in the standard group. Using the Fisher exact test, there was an association with a reduced incidence of hypersensitivity reactions with the extended infusion schedule (P<0.001).

CONCLUSION

Our data suggest appropriate premedication and prophylactic conversion to an extended infusion during carboplatin retreatment may reduce hypersensitivity reactions.

Incidence of Carboplatin-related hypersensitivity reactions in Japanese patients with gynecologic malignancies

Carboplatin is one of the most commonly used and well-tolerated agents for gynecologic malignancies. The rate of hypersensitivity reactions (HSRs) in the overall population of patients receiving carboplatin has been reported to increase after multiple doses of the agent. We retrospectively analyzed the incidence, clinical features, management, or outcome of carboplatin-related HSRs in 113 Japanese patients with gynecologic malignancies and the possibility of rechallenge with the drug. We intravenously administered carboplatin after paclitaxel or docetaxel. Mild HSRs are resolved by temporary interruption of carboplatin infusion, an additional antihistamine, and/or a corticosteroid. If HSRs arose, carboplatin was diluted, not exceeding 1 mg/mL, and slowly infused over 2 hours in subsequent cycles. Ten patients experienced carboplatin HSRs, with an overall incidence of 8.85%. The first HSR episode was mild in all cases. When retreated with carboplatin, 4 exhibited severe HSRs. More than 9 cycles and/or more than 5000 mg of carboplatin administration significantly increased the incidence of HSRs. In particular, carboplatin treatment beyond 15 cycles and/or 8000 mg increased the risk of severe HSRs (P < 0.0001). The incidence of HSRs in the ovarian carcinoma group was significantly greater than that in the uterine carcinoma group (P = 0.0046). Careful attention should be paid to HSRs during carboplatin treatment beyond 9 cycles and/or 5000 mg. The rate of severe HSRs greatly increases beyond 15 cycles and/or 8000 mg. Further studies are needed to identify potential risk factors that may contribute to the development of carboplatin HSRs and to decrease the risk of reactions.

[Platinum salts hypersensitivity]

It become usually after 4 to 8 courses of treatment. A long platin free interval is an increased risk of reaction. Clinical manifestations are various and can be separate in light to mild or severe reactions. Diagnose is retrospective with results of skin test. Prick test and IDR (using sequentially diluted platin salt and delayed reading) are the most available, essentially in case of acute reaction (<2h after injection of platin salt). IDR realized 30 min before injection of platin salt can be a good predictive test of hypersensitivity reaction. Management of this adverse effect depends on clinical manifestation: light to mild: careful re-introduction with a desensitization protocol; severe: no re-introduction. If it's necessary, careful replacement by another platin salt can be possible, eventually in accordance with results of IDR to all platinum salt.

Use of cisplatin without desensitization after carboplatin hypersensitivity reaction in epithelial ovarian and primary peritoneal cancer

OBJECTIVE

The purpose of this study was to evaluate the results of substituting cisplatin for carboplatin in women who experienced a carboplatin-associated hypersensitivity reaction while undergoing treatment for gynecologic cancers.

STUDY DESIGN

Using a comprehensive data repository, we identified all epithelial ovarian cancer and primary peritoneal cancer patients who experienced a documented significant hypersensitivity reaction to carboplatin and were subsequently treated with cisplatin at our institution from 1995 to the present. We also performed a review of published case reports of similar patient management.

RESULTS

We identified a total of 24 patients who met inclusion criteria. Eighteen patients (75%) tolerated cisplatin without any adverse events. Six patients (25%) eventually developed a reaction to cisplatin; none was life threatening, and only 1 required hospitalization. Twenty-three of the 24 patients (96%) tolerated at least 1 cycle of cisplatin. Of the 5 patients who initially tolerated cisplatin but eventually experienced a reaction, the mean number of cycles tolerated was 3.4.

CONCLUSION

The use of cisplatin without desensitization is a reasonable approach for continuing platinum-based chemotherapy in patients with a significant carboplatin hypersensitivity reaction. Patients should be advised of risks and closely monitored, given published case reports of anaphylaxis.

Hypersensitivity and idiosyncratic reactions to oxaliplatin

BACKGROUND

Oxaliplatin is a third-generation platinum analog that is used to treat a variety of solid tumors, particularly colorectal carcinoma. Patients may develop hypersensitivity reactions, although this complication occurs infrequently.

METHODS

Three patients developed hypersensitivity reactions to oxaliplatin while undergoing treatment on a Phase I trial of oxaliplatin and capecitabine. An Entrez PUBMED search was performed to identify other cases.

RESULTS

Two patients experienced the abrupt onset of erythema alone or with pruritus during the 9th and 11th infusions of oxaliplatin, whereas the other patient developed fever and mild dyspnea a few hours after the 9th oxaliplatin infusion. All 3 patients were rechallenged successfully for at least 1 additional oxaliplatin infusion by using oral dexamethasone, 20 mg orally, 6 and 12 hours before the administration of oxaliplatin and by administering intravenously 125 mg of solumedrol, 50 mg of diphenhydramine, and 50 mg of cimetidine 30 minutes before oxaliplatin. The literature review suggests two distinct patterns of reactions: classic hypersensitivity (as experienced by the first two patients) and idiosyncratic reactions (as experienced by the third patient).

CONCLUSIONS

Patients who develop mild to moderate hypersensitivity to oxaliplatin may be pretreated with steroids and antagonists of Type 1 and 2 histamine receptors, whereas patients who develop severe reactions are unlikely to tolerate further therapy.

Analysis of patients with epithelial ovarian cancer or fallopian tube carcinoma retreated with cisplatin after the development of a carboplatin allergy

OBJECTIVE

We report the outcome of seven patients treated for recurrent ovarian cancer with cisplatin after an allergic reaction to carboplatin. One case is presented in which a heavily pretreated patient suffered a severe anaphylactic reaction, which was refractory to standard resuscitative measures and resulted in her death.

METHODS

Six further patients who received cisplatin after documentation of an allergic reaction to carboplatin (CBDCA) for the treatment of recurrent epithelial ovarian cancer between 1993 and 2000 were identified from the MSKCC database. Electronic medical records were reviewed for relevant treatment and outcome data.

RESULTS

Five of six of these patients were successfully treated without further allergic reactions. One patient with platinum-refractory disease had an allergic reaction to carboplatin and subsequently to cisplatin.

CONCLUSION

Few patients with a carboplatin allergy are subsequently treated with cisplatin at our center. One patient suffered a serious hypersensitivity reaction following retreatment and died. Based on this limited experience, cross allergy can exist although the true incidence is not known. Routine retreatment of carboplatin-allergic patients with cisplatin in the relapsed setting cannot be recommended without careful consideration of potential risks and benefits.
