Reduction mammaplasty has been shown to effectively treat symptomatic breast hypertrophy with high patient satisfaction. Despite the obvious benefits, reimbursement requests for reduction mammaplasty are initially often refused by the patient's health insurance company, thereby frequently resulting in additional examinations and eventually extra expenses.

Primary outcome measures included median duration between the first request for reimbursement sent to the health insurance and the receipt of its approval, the number of requests needed per patient, as well as the number and type of additional outpatient visits conducted by specialists other than plastic surgeons, including the need for further diagnostic investigations and therapeutic measures.

There are no widely accepted treatment guidelines available. Lymphoma-like regimens with or without autologous or allogenic transplantation were the cornerstone of most therapeutic concepts. A few years ago, the CD123-directed immunoconjugate tagraxofusp emerged as a new valuable treatment option. The goal of our research was to collect available data on BPDCN-patients treated at large centres in Switzerland and worldwide and to draw conclusions regarding the incidence, clinical presentation, prognostic factors and therapeutic strategies.</p><p><strong>Methods: </strong>We collected data from BPDCN patients from leading Swiss haemato-oncology centres from 2005 to 2022. Furthermore, we reviewed and analysed the published literature (cohorts and case reports in peer-reviewed journals) from 1997 to 2020 (structured review of the literature).</p><p><strong>Results: </strong>We identified 115 international publications including 600 patients from all over the world. Most of them had very small sample sizes (only ten papers with more than ten patients) and all but one were retrospective or observational respectively. Most included patients were Europeans (n = 385, 64%) and Asians (n = 120, 20%), followed by Americans (n = 90, 15%) and patients from Australia/New Zealand (n = 3) and Africa (n = 2). BPDCN was more common in men with a predominance of 3:1. The median age (n = 414) at diagnosis was 66.5 years ranging from one month to 103 years. Newly diagnosed women were significantly younger than men (median: 62 vs 67 years, mean: 53.4 vs 59.3 years, p = 0.027) and less often had bone marrow infiltration and affected lymph nodes. Upfront allogenic transplantation as well as ALL regimens performed best, with response to first-line therapy clearly associated with better overall survival. The Swiss cohort contained 26 patients (23 males and 3 females) over 18 years (2005-2022). The median age at diagnosis was 68.5 years (range: 20-83). Ten patients underwent upfront stem cell transplantation (seven allogenic and three autologous), at least trending towards a better overall survival than other therapies.

The CodeBreak 200 trial demonstrated that sotorasib, a new drug targeting the G12C-mutated KRAS protein, modestly improved progression-free survival compared with docetaxel in patients whose cancer had progressed after receiving platinum chemotherapy and programmed cell death protein 1 (PD-1) / programmed death ligand 1 (PD-L1) inhibitors as first-line treatment. Consequently, sotorasib received temporary approval in Switzerland. Our analysis assessed the cost-effectiveness of sotorasib as a second-line treatment in Swiss patients with non-small cell lung cancer from the perspective of the Swiss statutory health insurance system.</p><p><strong>Methods: </strong>A partitioned survival model based on the CodeBreak 200 trial was constructed with a time horizon of 10 years and a discount rate of 3% for costs and quality-adjusted life years (QALYs). Parametric survival curves were fitted to the published Kaplan-Meier data, and survival was extrapolated. QALYs were obtained from the CodeBreak 100 trial and the literature. The costs of drugs, drug administration, diagnostics, disease management, and adverse events were considered. Because the price of sotorasib has not been established in Switzerland, two scenarios were analysed: the first used the published expected monthly United Kingdom (UK) price in Swiss francs (CHF 7870); the second used one-quarter of that price (CHF 1968), according to the lower dose used in the most recent trial, under the condition that one-quarter of the original sotorasib dose is equally effective.

For sotorasib versus docetaxel, our estimation showed no difference in QALYs (1.28 QALYs for both treatments), as the reduced adverse events reported in CodeBreak 200 for sotorasib had a minimal impact on the QALYs in our calculation. This made an incremental cost-effectiveness ratio (ICER) calculation irrelevant. Total per-patient costs were CHF 138,894 for the full sotorasib dose, CHF 82,741 for the one-quarter dose, and CHF 80,383 for docetaxel.
