Breast Cancer: Modern Treatment Methods and Innovations in Oncology

Evolution of Cancer Treatment Approaches: From Tradition to Innovation

Breast cancer, like other oncological diseases, requires a comprehensive approach to treatment. Traditional methods, such as surgery, chemotherapy, and radiation therapy, have long formed the basis of oncological practice. However, despite their efficacy, these approaches are often associated with limited therapeutic effect and significant adverse events, which substantially affects the quality of patients' lives [2]. The continuous search for ways to improve treatment outcomes and minimize toxicity stimulates the development of new, more targeted and personalized strategies.

Nanotechnology in the Fight Against Cancer: Metal-Organic Frameworks (MOFs)

One of the most promising areas in modern oncology is the application of nanotechnology. In particular, metal-organic frameworks (MOFs) represent innovative nanoplatforms that are actively being researched to improve cancer therapy [2]. MOFs are unique materials consisting of metal ions or clusters connected by organic ligands via coordination bonds. Their key advantages include:

• Controlled morphology and tunable diameter;
• Diverse composition and adjustable porosity;
• High specific surface area and easy functionalization [2].

These properties make MOFs ideal candidates for targeted drug delivery, enhancing their stability and efficacy, as well as reducing systemic side effects. They can be used to improve various therapeutic methods, including radiotherapy, chemotherapy, chemodynamic therapy, phototherapy, starvation therapy, and immunotherapy, opening new possibilities for combination treatment [2].

Targeted Therapy and Immunotherapy: A Personalized Approach

The growing understanding of the molecular mechanisms of cancer has led to the emergence of targeted therapy, which focuses on specific molecular targets involved in tumor growth and spread. For instance, in aggressive anaplastic thyroid cancer, the combination of BRAF and MEK inhibitors has shown significant and sustained effects in patients with the BRAFV600E mutation, achieving a response rate of 69% [3]. This example demonstrates the potential of targeted intervention against genetic alterations characteristic of the tumor.

Immunotherapy is also showing promising results in combating various types of cancer, including those with complex immune profiles [3, 7]. This approach aims to activate the patient's own immune system to recognize and destroy cancer cells. In the case of anaplastic thyroid cancer, as well as non-muscle-invasive bladder cancer, immunotherapy has shown promising, albeit more limited, results [3, 7]. New insights into the immune profile of tumors significantly improve and provide new accessible treatment strategies [7].

Overall, modern oncology is moving from empirical approaches to therapy based on a deep understanding of tumor biology and drug mechanisms of action [1]. This approach, which can be termed "mechanism-oriented therapy," allows for more precise selection of treatment regimens, taking into account the specific features of the disease and individual patient characteristics [1].

Prospects for Combination Therapy and New Delivery Systems

To increase treatment efficacy and overcome therapeutic resistance, combination therapy—combining multiple modalities to target the tumor—is becoming increasingly important [2]. This may include combining traditional methods with new biological agents or nanotechnologies. For example, in ovarian cancer, despite decades of experience with various chemotherapeutic agents, long-term survival remains low, emphasizing the need to develop new chemotherapeutic agents and effective biological agents used both in combination and as maintenance therapy [4].

The development of new drug delivery systems also plays a key role. Alongside MOFs, other innovative systems are being developed capable of delivering therapeutic agents directly to the tumor while minimizing impact on healthy tissues [7]. This is particularly relevant for fields such as intravesical therapy for bladder cancer, where new technologies and delivery systems are showing promising results [7].

The Future of Oncology: An Interdisciplinary Approach

The future of treatment for breast cancer and other oncological diseases lies in the further development of an interdisciplinary approach that integrates advances in surgery, radiation therapy, chemotherapy, targeted therapy, immunotherapy, and nanotechnology. Numerous clinical trials are actively underway, evaluating the efficacy of new kinase inhibitors and immunotherapeutic drugs [3]. Understanding disease mechanisms, including autoimmune dysregulation and metabolic disorders, contributes to the development of more targeted treatment methods [6]. The goal of all these efforts is not only to improve survival rates but also to reduce therapy toxicity and maintain a high quality of life for patients [4].
