Proof of concept for low dose and delayed release of tigilanol tiglate in the treatment of equine sarcoids

Gideon P. Stemmet, Peter Parsons, Jenny Johns, Paul Reddell, Raphael Labens

Intra-tumoural administration of tigilanol tiglate has been shown effective in local treatment of cutaneous equine neoplasias. The drug causes rapid oncolysis and tumour slough, but may also be associated with comorbidities in sensitive and/or intricate anatomical sites due to its initial pro-inflammatory mode of action. Here we describe two approaches to optimise and further de-risk treatment of equine sarcoids with tigilanol tiglate, especially in difficult locations. Firstly, we provide preliminary clinical and …

Prospective Clinical Trial on Expanding the Eligibility Criteria for Targeted Axillary Dissection after Neoadjuvant Systemic Therapy in Breast Cancers with Advanced Nodal Disease

A. J. T. Lee, B. H. H. Cheung, D. T. K. Suen, A. Kwong

Abstract Background Targeted axillary dissection (TAD) is an established axillary restaging approach in breast cancer after neoadjuvant chemotherapy (NAC), but evidence to date has focused largely on clinical N1 disease with limited nodal involvement. For higher nodal burden patients, axillary dissection (AD) is still frequently performed despite high axillary pathologic complete response (pCR) rates. We hypothesized that TAD is noninferior to AD for nodal staging in patients with advanced nodal disease. Patients a …

Longitudinal In Vivo Imaging at Single-Lesion Resolution Identifies Allele-Associated Response and Resistance Dynamics in EGFR-Mutant Lung Cancer

Eva Cabrera San Millan, Daniele Panetta, Paolo Armanetti, Mauro Quaglierini, Alessandro Zega, Raffaella Mercatelli, Emilia Bramanti, Luca Menichetti, Giorgia Maroni, Elena Levantini

Acquired resistance to targeted therapies is inevitable in EGFR-mutant non-small cell lung cancer (NSCLC), yet the principles governing its emergence in vivo remain incompletely understood. In particular, how lesion-level response patterns vary across distinct EGFR allele contexts during therapy has not been systematically examined at single-lesion resolution. Here, we establish a longitudinal in vivo imaging platform enabling single-lesion resolution tracking of tumor behavior during therapy in genetically enginee …
