Sarcoma means cancer of which organ/tissue?

Appeared in: Raj. CHO - 2023

Explanation

Option A: Cancers originating from glandular tissue are known as adenocarcinomas.
Option B: Cancers originating from the epithelial layer of the skin are called carcinomas (e.g., basal cell carcinoma, squamous cell carcinoma).
Option C: Cancers that arise from the cells of the lymphatic system (lymphocytes) are called lymphomas.

Visual 1: Diagram - An infographic illustrating the different origins of cancer. It should show three main branches: Epithelial tissue leading to Carcinoma, Connective tissue leading to Sarcoma, and Lymphoid tissue leading to Lymphoma/Leukemia, with examples under each branch.

Clinical Relevance

Nursing practice connection: Knowing Classification of malignant neoplasms based on their tissue of origin helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Understanding the tissue of origin is critical because it determines the cancer's behavior, including its pattern of spread (metastasis).
Sarcomas typically spread through the bloodstream (hematogenously), most commonly to the lungs. Nurses caring for patients with sarcoma should be vigilant for respiratory symptoms like a new cough or shortness of breath.
Carcinomas, in contrast, most often spread through the lymphatic system to nearby lymph nodes first. This is why lymph node biopsies are a standard part of staging for many carcinomas.

How to Approach the Question

This is a factual recall question that tests your knowledge of basic oncologic terminology.
Identify the key term in the question: 'Sarcoma'.
Recall the fundamental classification of cancers based on their tissue of origin.
Associate 'Sarcoma' with its corresponding tissue type: Connective Tissue (mesenchyme).
Evaluate the given options. 'Connective tissue' is listed as an option.
Mentally differentiate from other cancer types to confirm your answer: Carcinoma (epithelial tissue), Lymphoma (lymphatic tissue), and Leukemia (blood-forming cells).
