Question 1

What is the Meaning of Molecular Oncology?

Accepted Answer

Molecular Oncology is a specialized scientific domain investigating molecular and cellular mechanisms underlying cancer development, progression, and treatment response. It focuses on identifying genetic alterations, protein abnormalities, and signaling pathways driving malignant transformation. This discipline integrates molecular biology, genetics, and cell biology to understand oncogenesis fundamentally.

Question 2

What is the Context of Molecular Oncology?

Accepted Answer

This field operates within human physiology and pathology, addressing dysregulation of normal cellular processes leading to uncontrolled cell growth and metastasis. It examines how aberrations in DNA, RNA, and protein function disrupt cellular homeostasis, affecting cell cycle control, apoptosis, and intercellular communication. Understanding these molecular deviations provides crucial insights into disease biology.

Question 3

What is the Significance of Molecular Oncology?

Accepted Answer

Molecular Oncology holds significant clinical importance by informing personalized cancer therapy and improving patient outcomes. Its findings enable tumor classification based on unique molecular profiles, guiding targeted therapy selection, predicting efficacy, and identifying resistance mechanisms. This precision approach minimizes collateral damage while maximizing therapeutic impact.

Question 4

What is the Mechanism of Molecular Oncology?

Accepted Answer

At its core, Molecular Oncology elucidates how genetic mutations, such as oncogene activation or tumor suppressor gene inactivation, alter intracellular signaling cascades. These molecular changes affect growth factor receptors, kinase activities, or DNA repair pathways, leading to aberrant cell proliferation and survival. It also investigates epigenetic modifications contributing to oncogenesis.

Question 5

What is the Application of Molecular Oncology?

Accepted Answer

In clinical practice, Molecular Oncology is applied through molecular diagnostic tests, including next-generation sequencing and immunohistochemistry, to detect biomarkers in tumor tissue or circulating tumor DNA. These tests identify actionable mutations, gene fusions, or amplifications targetable by small molecule inhibitors or monoclonal antibodies, allowing tailored treatment strategies.

Question 6

What is the Metric of Molecular Oncology?

Accepted Answer

The effects of molecular oncology-guided interventions are measured by various clinical and laboratory metrics. These include tumor response rates assessed by imaging (e.g., CT, MRI), progression-free survival, overall survival, and monitoring of circulating tumor biomarkers. Molecular assays can also quantify minimal residual disease, providing early indications of treatment success.

Question 7

What is the Risk of Molecular Oncology?

Accepted Answer

Risks associated with molecular oncology approaches include potential misinterpretation of complex genomic data, leading to inappropriate therapy selection. Targeted therapies, while specific, can still induce significant side effects, and acquired drug resistance is a common challenge requiring continuous monitoring. Reliance on sophisticated technology also presents accessibility and cost barriers.
