Background: Novel antibody-drug conjugates (ADCs) drugs present a promising anti-cancer treatment, although survival benefits for HER2-positive advanced breast cancer (BC) remain controversial. The aim of this meta-analysis was to evaluate the comparative effect of ADCs and other anti-HER2 therapy on progression-free survival (PFS) and overall survival (OS) for treatment of HER2-positive locally advanced or metastatic BC.
Methods: Relevant randomized controlled trials (RCTs) were retrieved from five databases. The risk of bias was assessed with the Cochrane Collaboration's tool for RCTs by RevMan5.4 software. The hazard ratio (HR) and 95% confidence intervals (CIs) were extracted to evaluate the benefit of ADCs on PFS and OS in HER2-positive advanced BC by meta-analysis.
Results: Meta-analysis of six RCTs with 3870 patients revealed that ADCs significantly improved PFS (HR: 0.63, 95% CI: 0.49-0.80, P = 0.0002) and OS (HR: 0.79, 95% CI: 0.72-0.86, P < 0.0001) of patients with HER2-positive locally advanced or metastatic BC. Subgroup analysis showed that PFS and OS were obviously prolonged for patients who previously received HER2-targeted therapy. Sensitivity analysis and publication bias suggested that the results were stable and reliable.
Conclusion: Statistically significant benefits for PFS and OS were observed with ADCs in HER2-positive locally advanced or metastatic BC, especially for those who received prior anti-HER2 treatment.

Background: HER2 expression has been confirmed to be associated with bladder cancer aggressiveness. Anti-HER2 RC48-ADC is approved in China for the treatment of patients with advanced urothelial carcinoma with failed chemotherapy who are HER2 positive (IHC 2 + or 3 +). The discovery of HER2 positivity in urothelial carcinoma and the development of anti-HER2 drugs have brought new hope for bladder preservation treatment in MIBC.

Background: In the current era of targeted axillary dissection (TAD), there are still cases where axillary lymph node dissection (ALND) is indicated, but histopathological examination confirms the regression of nodal metastases (ypN0). In this situation, ALND may represent undesirable overtreatment.
Methods: A retrospective study at the Comprehensive Cancer Centre was conducted based on a prospectively maintained database.

In the primary analysis of the open-label phase III PRECIOUS study, pertuzumab retreatment combined with trastuzumab plus chemotherapy of physician's choice (PTC) significantly improved investigator-assessed progression-free survival (PFS) compared with trastuzumab plus physician's choice chemotherapy (TC) in patients with human epidermal growth factor receptor 2 (HER2)-positive locally advanced/metastatic breast cancer (LA/mBC). Here, we report final overall survival (OS) at the median follow-up of 25.8 months.

Background: Trastuzumab deruxtecan (TDXd) is an antibody-drug conjugate that has demonstrated impressive activity in randomized controlled clinical trials in the context of patients with HER2-amplified and HER2-low metastatic breast cancer. We aimed to review the activity and adverse event profile of TDXd in heavily pretreated breast cancer patients in real practice.
Methods: We describe a single-center retrospective case series of metastatic breast cancer patients who were treated with TDXd.

Background: The prognosis for urothelial carcinoma remains poor, with limited therapeutic options, emphasizing the need for further research into targeted therapies. The prognostic and predictive significance of human epidermal growth factor receptor 2 (HER2) expression in urothelial carcinoma remains unclear, with previous studies reporting conflicting results.
Methods: We conducted a retrospective analysis of advanced urothelial carcinoma cases diagnosed between January 2017 and December 2022.
