Assessment of Quality of Life and Treatment Outcomes of Patients With Persistent Postchemotherapy Alopecia
Persistent alopecia occurs in a subset of patients undergoing chemotherapy, yet the quality of life (QOL) of these patients and their response to therapy have not been described in a large patient cohort.
To characterize the clinical presentation of patients with persistent chemotherapy-induced alopecia (pCIA) or endocrine therapy-induced alopecia after chemotherapy (EIAC) and their QOL and treatment outcomes.
A retrospective multicenter cohort of 192 women with cancer treated with cytotoxic agents who received a clinical diagnosis of persistent alopecia (98 with pCIA and 94 with EIAC) between January 1, 2009, and July 31, 2017, was analyzed. All patients were from the dermatology service in 2 comprehensive cancer centers and 1 tertiary-care hospital. Data on demographics, chemotherapy regimens, severity, clinical patterns, and response to hair-growth promoting agents were assessed. Data from the Hairdex questionnaire were used to assess the QOL of patients with alopecia.
The clinical presentation, response to dermatologic therapy, and QOL of patients with pCIA were assessed and compared with those of patients with EIAC.
A total of 98 women with pCIA (median age, 56.5 years [range, 18-83 years]) and 94 women with EIAC (median age, 56 years [range, 29-84 years]) were included. The most common agents associated with pCIA were taxanes for 80 patients (82%); the most common agents associated with EIAC were aromatase inhibitors for 58 patients (62%). Diffuse alopecia was predominant in patients with pCIA compared with patients with EIAC (31 of 75 [41%] vs 23 of 92 [25%]; P = .04), with greater severity (Common Terminology Criteria for Adverse Events, version 4.0, grade 2) among patients with pCIA (29 of 75 [39%] vs 12 of 92 [13%]; P < .001). A negative emotional effect was reported by both groups. After treatment with topical minoxidil or spironolactone, moderate to significant improvement was observed for 36 of 54 patients with pCIA (67%) and for 32 of 42 patients with EIAC (76%).
Persistent chemotherapy-induced alopecia is frequently more severe and diffuse when compared with EIAC, and both groups of patients experienced a negative effect. A modest benefit was observed with dermatologic therapy. Additional studies are warranted to develop effective strategies for prevention and effective therapy for pCIA and EIAC

The PARP Inhibitor Veliparib Can Be Safely Added to Bendamustine and Rituximab and Has Preliminary Evidence of Activity in B-Cell Lymphoma
The PARP inhibitor veliparib enhances the cytotoxicity of alkylating agents. This phase I study evaluated veliparib with the bifunctional alkylator bendamustine (VB) in patients with relapsed/refractory lymphoma, multiple myeloma, and solid malignancies, with a cohort expansion of VB with rituximab (VBR) in patients with B-cell lymphomas.
This dose-escalation study evaluated safety, pharmacokinetics, and preliminary efficacy of veliparib (20-400 mg twice a day, days 1-7 of 28-day cycle) and bendamustine (70 and 90 mg/m
intravenously, days 1 and 2). A cohort expansion was conducted, which combined veliparib and bendamustine at the maximum tolerated dose (MTD) with rituximab (375 mg/m
, day 1) in patients with B-cell lymphomas. Thirty-four patients were treated in seven dose-escalation cohorts and seven patients in the dose-expansion cohort.
The MTD was veliparib 300 mg twice daily plus bendamustine 90 mg/m
Dose-limiting toxicities (DLT) were anemia, nausea, hypertension, and hyperhidrosis. Grade ≥3 toxicities included lymphopenia (87.8%), anemia (19.5%), neutropenia (12.2%), thrombocytopenia (9.8%), leukopenia (9.8%), nausea (7.3%), and hypophosphatemia (7.3%). Apparent veliparib clearance was slightly lower than previously reported. Of 14 patients with lymphoma evaluable for response, five of seven (71%) on VB and six of seven (86%) on VBR achieved objective response. One patient with multiple myeloma achieved partial response.
VB and VBR were generally well-tolerated. VBR had preliminary clinical activity in patients with B-cell lymphoma, which warrants further investigation in a phase II trial. This trial was registered at www.clinicaltrials.gov as NCT01326702
