Cold thermal injury from cold caps used for the prevention of chemotherapy-induced alopecia.

INTRODUCTION: The use of scalp cooling for the prevention of chemotherapy-induced alopecia (CIA) is increasing. Cold caps are placed onto the hair-bearing areas of the scalp for varying time periods before, during, and after cytotoxic chemotherapy. Although not yet reported, improper application procedures could result in adverse events (AEs). At present, there are no evidence-based scalp cooling protocols, and there is no regulatory oversight of their use. OBJECTIVE: To report the occurrence of cold thermal injury (frostbite) on the scalp, following the use of cold caps for the prevention of CIA. MATERIALS AND METHODS: We identified four patients who developed cold thermal injuries on the scalp following the application of cold caps. Medical records were analyzed to retrieve the demographic and clinical characteristics. RESULTS: The cold thermal injuries in our patients were grade 1/2 in severity and improved with topical interventions and interruption of cold cap use, although grade 1 persistent alopecia ensued in 3 patients. The true incidence of such injuries in this setting, however, remains unknown. CONCLUSIONS: Cold thermal injuries are likely infrequent and preventable AEs that may result from improper device application procedures during cold cap use. Although these untoward events are usually mild to moderate in severity, the potential occurrence of long-term sequelae (e.g., permanent alopecia and scarring) or the need to discontinue cold cap use, are not known. Prospective studies are needed to further elucidate the risk and standardize healthcare delivery methods, and to improve patient/supportive/healthcare provider education.

The Impact of Independent Chemotherapy Prescribing by Advanced Practice Providers on Patient Safety and Clinician Satisfaction.

BACKGROUND: Literature on advanced practice providers (APPs) prescribing chemotherapy independently, without physician cosignature, is limited. OBJECTIVES: This project assessed safety and provider satisfaction for an existing independent APP chemotherapy prescribing privilege at a National Cancer Institute-designated comprehensive cancer center. METHODS: Rate of Reporting to Improve Safety and Quality events associated with APPs with independent chemotherapy prescribing privileges was compared to that of physicians during a three-year period. Satisfaction of APPs with independent chemotherapy prescribing privileges was evaluated. FINDINGS: The odds of a reported event were higher for physicians than for APPs. APP survey responses were positive for readiness, confidence, and satisfaction with independent chemotherapy prescribing privilege.

Harmonization of the Upfront Osteosarcoma Treatment Paradigm for Adolescents and Young Adults.

Limited guidance exists on streamlining cancer therapy for adolescent and young adult (AYA) patients 15-39 years of age, as much of the current data are extrapolated from pediatric or adult counterparts and can differ significantly between the two care models. Harmonization of standard treatment approaches has the potential to improve outcomes and establish a foundation for the development of future clinical trials. We present our experience harmonizing treatment and supportive care regimens for AYA patients with osteosarcoma receiving treatment with methotrexate, doxorubicin, and cisplatin (MAP) therapy on the pediatric and adult sarcoma services at the Memorial Sloan Kettering Cancer Center.

A Phase I Study of Alpelisib in Combination with Trastuzumab and LJM716 in Patients with PIK3CA-Mutated HER2-Positive Metastatic Breast Cancer.

PURPOSE: Activating mutations in PIK3CA promote resistance to HER2-targeted therapy in breast cancer; however, inhibition of PI3K alone leads to escape via feedback upregulation of HER3. Combined inhibition of HER2, HER3, and PI3K overcomes this mechanism preclinically. PATIENTS AND METHODS: This phase I study investigated the MTD of alpelisib given in combination with trastuzumab and LJM716 (a HER3-targeted antibody) in patients with PIK3CA-mutant HER2-positive (HER2+) metastatic breast cancer (MBC) using the continual reassessment method. Secondary analyses included efficacy and exploratory correlative studies. RESULTS: Ten patients were treated initially with daily alpelisib (arm A). Grade ≥3 adverse events seen in ≥2 patients included diarrhea (n = 6), hypokalemia (n = 3), abnormal liver enzymes (n = 3), hyperglycemia (n = 2), mucositis (n = 2), and elevated lipase (n = 2). The MTD of alpelisib in arm A was 250 mg daily. This prompted the opening of arm B in which 11 patients received intermittently dosed alpelisib. Grade ≥3 adverse events seen in ≥2 patients included diarrhea (n = 5), hypokalemia (n = 3), and hypomagnesemia (n = 2). The MTD of alpelisib in arm B was 350 mg given 4 days on, 3 days off. Among 17 patients assessed, 1 had a partial response, 14 had stable disease, and 2 had disease progression at best response. Five patients had stable disease for >30 weeks. mRNA profiling of pre- and on-treatment tissue demonstrated PIK3CA target engagement by alpelisib via induction of downstream signaling and feedback pathways. CONCLUSIONS: Combination treatment with alpelisib, trastuzumab, and LJM716 was limited by gastrointestinal toxicity. Further efforts are warranted to target the PI3K pathway in HER2+ MBC.

Electronic Chemotherapy Order Entry: A Major Cancer Center's Implementation.

Implementation of a computerized provider order entry system for complex chemotherapy regimens at a large cancer center required intense effort from a multidisciplinary team of clinical and systems experts with experience in all facets of the chemotherapy process. The online tools had to resemble the paper forms used at the time and parallel the successful established process as well as add new functionality. Close collaboration between the institution and the vendor was necessary. This article summarizes the institutional efforts, challenges, and collaborative processes that facilitated universal chemotherapy computerized electronic order entry across multiple sites during a period of several years.

Bevacizumab 5 mg/kg can be infused safely over 10 minutes.

PURPOSE: Bevacizumab is a humanized monoclonal antibody that targets vascular endothelial growth factor. As a result of concerns for potential infusion-related hypersensitivity reactions (HSRs), initial phase I trials used a 90-, 60-, 30-minute initial infusion sequence. We sought to determine if the initial prolonged infusion was still necessary and if an infusion time of fewer than 30 minutes could be safely used. METHODS: We used computerized pharmacy records to identify all patients who received bevacizumab at our institution in the first 2 years of commercial availability (February 1, 2004, to June 30, 2006). Our institutional adverse drug reaction reporting program was used to identify any infusion reactions possibly related to bevacizumab, and patient medical records were reviewed for confirmation. RESULTS: A total of 1,077 patients were treated with 10,606 doses of bevacizumab, and 765 of these patients received a 5-mg/kg dose (total of 8,494 doses). No HSRs occurred with the 90-, 60-, 30-minute infusion sequence in the first 202 patients. The standard infusion rate was then modified to 30 minutes for all bevacizumab doses. No HSRs were encountered. The infusion was again modified to a rate of 0.5 mg/kg/min. Of the 370 patients who received a total of 2,311 doses of bevacizumab at 5 mg/kg over 10 minutes, six (1.6%) experienced events of minor clinical consequence that were possibly consistent with nonserious HSRs. CONCLUSION: Ninety- and 60-minute initial infusion times are unnecessary. Use of a standard infusion rate of 0.5 mg/kg/min is safe, logical, and the current policy at our institution.

Establishing clinical guidelines for the management of acute hypersensitivity reactions secondary to the administration of chemotherapy/biologic therapy.

A performance improvement initiative was undertaken to establish treatment guidelines for the management of infusion-related hypersensitivity reactions (iHSRs) secondary to the administration of chemotherapy/biologic therapy and to develop an efficient process to ensure application of these standards in the care of patients at increased risk of experiencing iHSRs. The project yielded a standardized approach that ensures the application of an evidence-based standard of care in managing these reactions. In addition, the effort resulted in improvements in the reporting of this type of adverse drug reaction (ADR) to the institutional ADR reporting program.

Arterial desaturation syndrome following pleurodesis with talc slurry: incidence, clinical features, and outcome.

The objectives were to define the incidence, risk factors, clinical features and outcome of arterial desaturation syndrome following talc pleurodesis in patients with malignant pleural effusions. This retrospective, observational study took place at a tertiary care cancer center in New York. All patients were those with malignancy who underwent pleurodesis with talc in 1998 at Memorial Sloan Kettering Cancer Center. Characteristics of patients are described by using summary statistics. Differences between groups were assessed with the Fisher's exact statistic for categorical variables and Student's t-test for continuous variables. Among patients who were considered to have arterial desaturation syndrome, we evaluated the relation of SaO2/FIO2 pre- and post-talc installation using a paired Student's t-test. During 1998, 120 patients underwent pleurodesis with talc, and 8 (7%) developed arterial desaturation following the procedure. Symptoms included chest pain, dyspnea, fever, and increased need for oxygen supplementation developed typically within 1 day. Three of the eight patients in this series required mechanical ventilation, but all recovered uneventfully after treatment, which included high-dose corticosteroids. Patients with breast and ovarian cancer appeared to be at increased risk for this complication compared to those patients with other types of cancer (p = 0.01). Approximately 7% of patients who have undergone sclerosis with talc for a malignant pleural effusion will develop arterial desaturation with clinically significant hypoxia requiring supplemental oxygen following the procedure. It appears that most patients recover from this complication and that those with breast and ovarian cancer may be at higher risk.
