10 topics with brief reviews: definitions, key facts, and class questions.
This chapter is dedicated to the basic principles of oncology, which are essential for the clinical practice of a modern physician. We will discuss the etiology and pathogenesis of neoplasms, study their classification and key oncological syndromes, including the syndrome of "minor signs".
This section covers the entire workflow for managing an oncology patient: from taking a specific medical history and conducting a physical examination to instrumental diagnostics and staging according to the international TNM system. You will learn the specifics of surgical intervention (the principles of ablastic and antiblastic surgery), get acquainted with the basics of radiation therapy and chemotherapy, and understand how the oncological service is organized.
During practical classes and examinations, the TNM system, principles of oncological alertness, early diagnosis algorithms, and criteria for radical surgical treatment are questioned most strictly. Pay special attention to the clinical picture and syndromes—this knowledge is what saves lives in the early stages of the disease.
What does the term "independence (autonomy)" mean when applied to a tumor?
Autonomy means that the growth, development, and metabolism of the neoplasm occur independently of the regulatory systems (nervous, endocrine, immune) of the body itself.
What is the difference between cancer and sarcoma?
Cancer (cancer) originates exclusively from epithelial tissue and accounts for 95% of malignant cases. Sarcoma (sarcoma) develops from connective tissue and is significantly less common, occurring in 5% of cases.
Is pain syndrome characteristic of the early stages of tumor development?
No, pain is almost never observed in the early stages. Mild general symptoms and discomfort come to the forefront.
Does an oncology patient always look emaciated?
No, wasting (emaciation) is not characteristic of early stages. Patients may maintain a healthy appearance and normal body weight; cachexia develops in advanced forms.
What does a "woody" consistency of a neoplasm indicate?
Such an extremely high density is typical of a cancerous tumor. It is usually combined with the absence of clear borders due to infiltrative growth into adjacent tissues.
Who should primarily demonstrate oncological alertness?
Physicians of all specialties without exception. This applies particularly to outpatient specialists (general practitioners and gynecologists), as patients first contact them.
