Human epidermal growth factor 2 (HER-2)-positive breast cancer represents 15–20% of all breast cancer subtypes and has an aggressive biological behavior with worse prognosis. The development of HER-2-targeted therapies has changed the disease’s course, having a direct impact on survival rates and quality of life. Drug development of HER-2-targeting therapies is a prolific field, with numerous new therapeutic strategies showing survival benefits and gaining regulatory approval in recent years. Furthermore, the acknowledgement of the survival impact of HER-2-directed therapies on HER-2-low breast cancer has contributed even more to advances in the field. The present review aims to summarize the newly approved therapeutic strategies for HER-2-positive breast cancer and review the new and exploratory HER-2-targeted therapies currently under development.

Gastric cancer is the fifth most common cancer worldwide and its incidence is rising. Surgery is the only curative strategy and its association with perioperative chemotherapy is now standard treatment for most resectable tumors. Despite treatment advances, disease relapse is high, even in early stages, and continued improvement in curative treatment is imperative. With deeper knowledge of gastric cancer heterogeneity, molecular subtypes, and the tumor immune microenvironment, new standard treatment strategies may emerge in the near future. This paper provides a comprehensive review of the current treatment landscape in resectable gastric cancer and future perspectives for the next decade regarding new agents such as targeted therapies, immunotherapy, antibody–drug conjugates, and the combination of multiple treatment modalities.

Background/Objectives: Breast cancer is the most common malignant neoplasm in women and the leading cause of cancer-related death. Approximately 50% of HER2-negative breast cancers exhibit low expression of this protein (HER2-low). Trastuzumab deruxtecan (T-DXd) is an antibody-drug conjugate targeting the HER2 receptor which has shown benefit in patients with HER2-low metastatic breast cancer in the DESTINY-Breast04 study. However, few data are available on its efficacy in real-world practice. Methods: We conducted a retrospective multicenter national study (eight centers) including patients with advanced HER2-low breast cancer (immunohistochemistry 1+ or 2+/ in situ hybridization negative) who started T-DXd treatment between January 2022 and March 2024. Patients had received at least one previous line of treatment. The primary endpoint was real-world progression-free survival (rwPFS) in patients with metastatic HER2-low breast cancer treated with T-DXd. The secondary endpoints were real-world overall survival (OS) and objective response rate (ORR). Results: The study included 35 patients (34 female and 1 male patient), with a median age of 54 years at the start of T-DXd. All patients had an ECOG-PS 0–1, and 26 patients (74%) had hormone receptor (HR)-positive disease. The median number of prior lines of treatment was 4 [1–7], and 23 patients (65.8%) had metastases in three or more sites. With a median follow-up of 7.8 months, rwPFS was 6 months (95% CI, 2.3–9.7), and OS was 15 months (95% CI, 4.7–25.3). In HR-positive patients, the median rwPFS was 6 months (95% CI, 1.2–10.7), compared to 4 months (95% CI, 2.1–5.9) in HR-negative patients. The overall ORR was 52.9%. Adverse events of grade 3 or higher were neutropenia (2.9%) and fatigue (2.9%). Conclusions: This study provides real-world data on T-DXd in the treatment of advanced HER2-low breast cancer. It is noteworthy that the population was heavily pre-treated and had a higher proportion of HR-negative patients, which may explain the lower efficacy compared to the DESTINY-Breast04 study.

Sexual dysfunction (SD) prevalence in lung cancer (LC) patients is largely unknown. This study aims to assess the prevalence of SD among LC patients at our center. We conducted a cross-sectional survey of 69 patients using a questionnaire on sexual activity and satisfaction. Participants were recruited from 1 July 2023 to 30 September 2024 and had to be diagnosed with LC, age > 18 years, able to read, and with at least 1 month of treatment. A total of 61 patients completed the survey, predominantly male (67.2%) with stage IV LC (68.9%). Less than half (45.9%) reported recent sexual activity, while many expressed little to no interest (55.7%) and minimal satisfaction with their sex life (42.8%). The factors affecting sexual satisfaction included fatigue (37.7%) and feelings of anxiety/stress (24.6%). The reasons for decreased sexual activity included a lack of interest (36.4%), difficulties with erection (24.2%), and issues with partners (24.3%). A significant association was found between SD and the perceived impact of LC on sexual life, with higher dysfunction scores linked to more negative reports. SD is common among LC patients. Implementing assessment strategies and interventions may improve the sexual life of these patients.
