Breast cancer (BC) is a global concern, with Peru experiencing a high incidence and mortality. Trastuzumab, a crucial treatment for human epidermal growth factor receptor 2-positive BC, is administered intravenously or subcutaneously (SC). This study evaluates the costs associated with both methods at Peru's Instituto Nacional de Enfermedades Neoplásicas.

Trastuzumab has marked a significant milestone in the management of this disease. It has been shown to improve prognosis in human epidermal growth factor receptor 2 (HER2)-expressing female patients, but its repercussions and efficacy are yet to be analyzed in a context with limited resources.

Methods: Patients were randomly assigned to osimertinib plus platinum-pemetrexed (combination) or osimertinib monotherapy until disease progression or discontinuation. Brain scans were performed in all patients at baseline and progression and at scheduled assessments until progression for patients with baseline CNS metastases; scans were assessed by neuroradiologist CNS blinded independent central review (BICR).
Article Synopsis
- - The study evaluated the effectiveness of adding durvalumab, a PD-L1 antibody, to standard chemoradiotherapy for patients with locally advanced cervical cancer, aiming to improve outcomes due to high recurrence rates despite existing treatments.
- - The CALLA trial was a phase 3, double-blind study involving 105 hospitals in 15 countries, focusing on patients with untreated cervical cancer who were randomly assigned to receive either durvalumab or a placebo alongside chemoradiotherapy.
- - The primary goal was to measure progression-free survival, while safety was assessed for those receiving at least one dose of the treatment, highlighting the rigorous methodology and safety monitoring throughout the trial.
Background: Osimertinib is a third-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) that is selective for EGFR-TKI-sensitizing and T790M resistance mutations. Evidence suggests that the addition of chemotherapy may extend the benefits of EGFR-TKI therapy.
Methods: In this phase 3, international, open-label trial, we randomly assigned in a 1:1 ratio patients with -mutated (exon 19 deletion or L858R mutation) advanced non-small-cell lung cancer (NSCLC) who had not previously received treatment for advanced disease to receive osimertinib (80 mg once daily) with chemotherapy (pemetrexed [500 mg per square meter of body-surface area] plus either cisplatin [75 mg per square meter] or carboplatin [pharmacologically guided dose]) or to receive osimertinib monotherapy (80 mg once daily).
