Retrospective assessment of chemotherapy/biotherapy toxicity in a Hispanic/Latinx population versus published study population.

INTRODUCTION: Eskenazi Health in Indianapolis, Indiana, USA. services diverse communities in Central Indiana, including the Hispanic/Latinx community. It has been postulated that this population experiences toxicities at a higher rate and with a faster onset than the general population when treated with chemotherapy or biotherapy. The published clinical trials that have evaluated chemotherapy/biotherapy efficacy and toxicity have not adequately represented the Hispanic/Latinx population. This retrospective analysis aims to analyze the incidence and severity of adverse drug events in the Hispanic/Latinx population compared to the general study population. METHODS: A retrospective chart review included patients reported as Hispanic/Latinx in the electronic medical record who had breast cancer, colon cancer, acute myeloid leukemia, or multiple myeloma currently receiving chemotherapy/biotherapy and/or received chemotherapy/biotherapy during the study period. Seventy-three instances of patients receiving chemotherapy/biotherapy and 46 unique patients were included in the final analysis. RESULTS: Of the 73 instances, 29 (40%) had toxicity at baseline prior to chemotherapy/biotherapy received during the study period. Of those 29 baseline toxicities, 26 (90%) of them had new toxicity during the study period. Of the 73 instances, 62 (85%) experienced toxicities during the study period. CONCLUSION: Ethnicity has a proven effect on medication efficacy and safety, but the specific impact of ethnicity on chemotherapy/biotherapy toxicity risk has not been well elucidated. This study found that a majority (85%) of Hispanic/Latinx patients treated with chemotherapy/biotherapy experienced toxicity of any grade, and the majority (90%) patients who had prior toxicity experienced another toxicity.

Retrospective analysis of the incidence and severity of acute kidney injury (AKI) in patients with head and neck cancer receiving weekly cisplatin with radiotherapy (RAISe-AKI).

INTRODUCTION: Low-dose, weekly cisplatin (40 mg/m2) regimens are currently utilized at Eskenazi Health in Indianapolis, Indiana for the treatment of head and neck cancer due to enhanced tolerability. This retrospective analysis analyzes the incidence, severity, and risk factors for AKI in patients who received this regimen. METHODS: A retrospective chart review was conducted including patients with head and neck cancer treated with weekly, low dose cisplatin (40 mg/m2) with concurrent radiotherapy (RT). From this criteria, 22 patients were identified and included in the final analysis. AKI was defined by the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. RESULTS: Of the 22 patients included, 12 (54.5%) experienced AKI, with 10 patients (45.5%) experiencing grade 1 AKI and 2 patients (9.1%) experiencing grade 2 AKI. Six patients (27.3%) required dose adjustments or delays due to renal adverse events, all of which had initial cisplatin total weekly doses of >70 mg. Those receiving a total weekly cisplatin dose of >70 mg were found to have a higher risk of developing an episode of AKI compared to the group receiving <70 mg (p = 0.029). CONCLUSION: This analysis showed patients receiving weekly doses >70 mg of cisplatin as their initial treatment dose for head and neck cancer were more likely to experience AKI. There are inconsistencies in the frequency of AKI in our study compared to published literature; however, this comparison is difficult due to the small sample size of our trial. This demonstrates the need for further investigation into the issue.

Virtually there: An innovative approach for training oncology pharmacy residents in gynecologic oncology.

OBJECTIVE: To develop an alternative approach to provide oncology pharmacy practice residents' education and training in the management of gynecologic malignancies in the absence of a specialist in this area at their institution. SETTING: Gynecologic oncology is a unique specialty in oncology. There is a need for more oncology clinical pharmacy specialists to participate in the care of patients with gynecologic malignancies as many do not have specific education in this area. PRACTICE DESCRIPTION: A virtual learning experience was developed that included all aspects of a typical experience with the exception of direct patient care. Postgraduate year 2 oncology pharmacy residents from 3 different programs were included. PRACTICE INNOVATION: Although the number of oncology clinical pharmacy specialists who are subspecialized in gynecologic oncology has grown, it is difficult to find experienced preceptors in gynecology oncology. We set to offer a virtual learning environment for programs that did not have a dedicated or highly specialized pharmacist in this area. EVALUATION: A pre- and postlearning assessment of the resident's knowledge of gynecologic malignancies was administered. Each trainee independently completed a validated 20-question gynecologic oncology knowledge assessment tool before and again after completion of all sessions. Midpoint and end-of-experience evaluations were completed via the phone with each resident. All evaluations were documented in PharmAcademic (McCreadie Group, Ann Arbor, MI), a required software program for postgraduate residency training programs. RESULTS: To date, 7 oncology pharmacy practice residents completed the virtual experience. A 42% improvement in scores pertaining to gynecologic oncology knowledge was identified. Residents were also satisfied with the overall virtual experience. Based on the assessment tool, all the residents gave positive evaluations with "always true" for 6 of the 7 questions. CONCLUSIONS: This pilot of a virtual experience was a successful platform to provide clinical knowledge and skills for oncology pharmacy residents in gynecologic oncology.

Assessment of bleeding incidences associated with rivaroxaban therapy in adults with solid tumors.

PURPOSE: Report bleeding incidences associated with rivaroxaban in adult patients with solid tumor malignancies requiring anticoagulation therapy. METHODS: This retrospective review was conducted at Indiana University Health, University Hospital and the Simon Cancer Center in Indianapolis, IN from January 2013 - February 2016. Patients were included if they had a solid tumor malignancy and prescribed rivaroxaban. Data were collected on 144 patients. Major bleeding was defined as bleeding requiring treatment (local, systemic treatment, blood cell transfusions) or hospitalization and minor bleeding was defined as bleeding not requiring treatment or hospitalization. RESULTS: Sixty-four (44%) patients experienced bleeding while on rivaroxaban. There were six cancer types that had a higher incidence of bleeding: bladder, breast, melanoma, pancreas, prostate, and renal cell cancers; 40% (6/15) of patients with bladder cancer experienced bleeding; 54% (7/13) with breast cancer experienced bleeding; 40% (4/10) of patients with melanoma experienced bleeding; 58% (11/19) of patients with pancreatic cancer experienced bleeding; 45% (10/22) of patients with prostate cancer experienced bleeding; and 56% (5/9) of patients with renal cell carcinoma experienced bleeding. No other data collected identified increased incidence of bleeding. CONCLUSIONS: Patients on rivaroxaban with a diagnosis of bladder, breast, melanoma, pancreas, prostate, or renal cell cancers had a higher incidence of bleeding compared to other solid tumors. Major bleeding was higher in bladder, breast, pancreas, and renal cell carcinomas, while minor bleeding was higher in patients with melanoma and prostate cancer.

Adjunct Histamine Blockers as Premedications to Prevent Carboplatin Hypersensitivity Reactions.

OBJECTIVE: The objective of this study was to evaluate the impact of premedications given as an adjunct to carboplatin on the incidence of hypersensitivity reactions in women with ovarian cancer. Medications of interest include a histamine1 (H1 ) and histamine2 (H2 ) blocker in addition to dexamethasone. METHODS: This was a retrospective chart review evaluating the addition of an H1 and H2 blocker in addition to dexamethasone as standard premedications on the incidence of carboplatin hypersensitivity reactions (CHRs) in women with ovarian cancer. MAIN RESULTS: The odds ratio for premedication use was 0.46 with a 95% confidence interval (0.17-1.27), suggesting that patients with premedication use had approximately half the risk of CHR compared with patients without premedication. The overall incidence of CHRs decreased from 7.9% at baseline to 3.2% after the addition of premedications. The incidence of CHRs was 5.2% in 58 patients with recurrent or progressive disease compared with 2.1% in 96 newly diagnosed patients. Lifetime dose greater than 3377 mg, number of cycles more than six, and progressive or recurrent disease were predictive factors of CHR in women with ovarian cancer. PRINCIPAL CONCLUSIONS: Total lifetime exposure to carboplatin remains the greatest predictive factor of CHR in women with ovarian cancer. Although data analysis indicates the addition of premedications for all ovarian cancer patients receiving carboplatin did not result in a statistically significant reduction in CHRs, a patient benefit in CHR reduction was observed. A prospective study is needed to confirm these findings.
