Abstract:
Bone metastases have a major impact on morbidity and on mortality in cancer patients. Despite its clinical relevance, metastasis remains the most poorly elucidated aspect of carcinogenesis. The biological mechanisms leading to bone metastasis establishment have been referred as "vicious circle," a complex network between cancer cells and the bone microenvironment. This review is aimed to underline the new molecular targets in bone metastases management other than bisphosphonates. Different pathways or molecules such as RANK/RANKL/OPG, cathepsin K, endothelin-1, Wnt/DKK1, Src have recently emerged as potential targets and nowadays preclinical and clinical trials are underway. The results from those in the advanced clinical phases are encouraging and underlined the need to design large randomised clinical trials to validate these results in the next future. Targeting the bone by preventing skeletal related events (SREs) and bone metastases has major clinical impact in improving survival in bone metastatic patients and in preventing disease relapse in adjuvant setting.
Insights
New molecular targets beyond bisphosphonates show promise for managing bone metastases, offering hope for improved patient survival and reduced cancer relapse. Further clinical trials are needed to validate these findings.
Area of Science:
- Oncology
- Cancer Biology
- Bone Metastasis Research
Background:
- Bone metastases significantly increase cancer patient morbidity and mortality.
- Metastasis is a poorly understood aspect of carcinogenesis, involving complex interactions between cancer cells and the bone microenvironment.
- Current management often relies on bisphosphonates, necessitating exploration of novel therapeutic strategies.
Purpose of the Study:
- To review emerging molecular targets for bone metastases management beyond traditional bisphosphonates.
- To highlight novel pathways and molecules showing potential in preclinical and clinical studies.
- To emphasize the need for large-scale clinical trials to validate new therapeutic approaches.
Main Methods:
- Review of current literature on molecular targets in bone metastasis.
- Identification of key pathways including RANK/RANKL/OPG, cathepsin K, endothelin-1, Wnt/DKK1, and Src.
- Analysis of ongoing preclinical and clinical trial data.
Main Results:
- Several novel molecular targets and pathways have emerged as promising for bone metastases treatment.
- Early clinical trial results for these targets are encouraging.
- The identified targets represent a shift towards more targeted therapies for bone metastasis.
Conclusions:
- New molecular targets offer potential for improved bone metastases management.
- Targeting these pathways may prevent skeletal-related events and improve survival in metastatic patients.
- Further large randomized clinical trials are crucial to confirm the efficacy and safety of these novel agents.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Non-Canonical Wnt Signaling Pathways
Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
