Many patients with metastatic human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC) are candidates for trastuzumab emtansine (T-DM1) treatment sometime in their disease history. KAMILLA evaluated safety of T-DM1 in patients with previously treated HER2-positive locally advanced or metastatic BC (advanced BC). KAMILLA (NCT01702571) is a single-arm, open-label, international, phase IIIb safety study of patients with HER2-positive advanced BC with progression after prior treatment with chemotherapy and a HER2-directed agent for MBC or within 6 months of completing adjuvant therapy. Patients received T-DM1 (3.6 mg/kg every 3 weeks) until unacceptable toxicity, withdrawal or disease progression. Among 2002 treated patients, median age was 55 years (range, 26-88; 373 [18.6%] aged ≥65 years), 1321 (66.0%) received ≥2 prior metastatic treatment lines and 398 (19.9%) had baseline central nervous system metastases. Adverse events (AEs) and serious AEs occurred in 1862 (93.0%) and 427 (21.3%) patients, respectively. Grade ≥3 AEs occurred in 751 (37.5%) patients; the three most common (individual Medical Dictionary for Regulatory Activity terms) were anaemia (3.0%), thrombocytopaenia (2.7%) and fatigue (2.5%). Median progression-free survival (PFS) was 6.9 months (95% confidence interval [CI], 6.0-7.6). Median overall survival (OS) was 27.2 months (95% CI, 25.5-28.7). With increasing lines of prior advanced therapy (0-1 versus 4+), median PFS and OS decreased numerically from 8.3 to 5.6 months and from 31.3 to 22.5 months, respectively. KAMILLA is the largest cohort of T-DM1-treated patients studied to date. Results are consistent with prior randomised studies, thereby supporting T-DM1 as safe, tolerable and efficacious treatment for patients with previously treated HER2-positive advanced BC.

This study presents comprehensive real-world data on the use of anti-human epidermal growth factor receptor 2 (HER2) therapies in patients with HER2-positive metastatic breast cancer (MBC). Specifically, it describes therapy patterns with trastuzumab (H), pertuzumab + trastuzumab (PH), lapatinib (L), and trastuzumab emtansine (T-DM1). The PRAEGNANT study is a real-time, real-world registry for MBC patients. All therapy lines are documented. This analysis describes the utilization of anti-HER2 therapies as well as therapy sequences. Among 1936 patients in PRAEGNANT, 451 were HER2-positive (23.3%). In the analysis set (417 patients), 53% of whom were included in PRAEGNANT in the first-line setting, 241 were treated with H, 237 with PH, 85 with L, and 125 with T-DM1 during the course of their therapies. The sequence PH → T-DM1 was administered in 51 patients. Higher Eastern Cooperative Oncology Group (ECOG) scores, negative hormone receptor status, and visceral or brain metastases were associated with more frequent use of this therapy sequence. Most patients received T-DM1 after treatment with pertuzumab. Both novel therapies (PH and T-DM1) are utilized in a high proportion of HER2-positive breast cancer patients. As most patients receive T-DM1 after PH, real-world data may help to clarify whether the efficacy of this sequence is similar to that in the approval study.

Patient-Centered Innovations, Education and Technology for Cancer Care and Cancer Research

Objective: Medical cancer treatment is often accompanied by appearance‐related side effects such as hair loss, skin irritation, and paleness, which can subsequently lead to psychosocial distress. Initial evidence suggests that beauty care interventions may reduce distress and improve quality of life (QoL), body image, and self‐esteem immediately.Methods: We investigated the effects of a brief beauty care intervention on self‐reported symptoms of depression, quality of life, body image, and self‐esteem in 39 female primary breast cancer patients with appearance‐related treatment side effects. Patients were randomly assigned either to an immediate intervention group (IG) or to a wait‐list control (WL). The intervention consisted of a single‐session group makeup workshop, a photo shooting, and of receiving professionally edited portrait and upper‐body photos.Results: While groups did not differ regarding any measure at the pretreatment baseline assessment, IG patients reported less symptoms of depression, higher QoL, and higher self‐esteem compared with baseline and compared with WL. Follow‐up at 8 weeks indicated moderate stability of these improvements.Conclusions: In contrast to previous research, results indicate beneficial short‐term and midterm effects of beauty care on psychological outcomes in patients with early breast cancer. These results emphasize the utility of this type of brief, low‐cost intervention in women undergoing medical cancer treatment in order to improve their well‐being.
