Bone Marrow Biopsy (S)

 a highly specialized and definitive diagnostic test used to examine the solid part of the bone marrow. Unlike bone marrow aspiration, which collects liquid marrow, a bone marrow biopsy removes a small core of bone and marrow tissue for detailed microscopic evaluation.

সহজভাবে বললে, এই পরীক্ষার মাধ্যমে Bone Marrow-এর গঠন (architecture), কোষের বিন্যাস এবং রোগের গভীরতা নির্ণয় করা হয়।

What is Bone Marrow Biopsy?

Bone marrow biopsy is a minor surgical procedure where a small cylindrical piece of bone marrow is taken, usually from the posterior iliac crest (hip bone). The tissue is then processed, sectioned, stained, and examined by an experienced pathologist.

Why is Bone Marrow Biopsy Done?

Doctors advise bone marrow biopsy when aspiration alone is not sufficient or when a deeper evaluation is required.

এই পরীক্ষা করা হয় বিশেষ করে যখন:

• Bone marrow aspiration report inconclusive হয়

• Blood cancer suspected or confirmed

• Marrow infiltration জানতে হয়

• Fibrosis বা marrow architecture দেখতে হয়

• Disease staging বা treatment response assess করতে হয়

Conditions Diagnosed by Bone Marrow Biopsy

Bone marrow biopsy helps diagnose and confirm:

Acute & Chronic Leukemia

• Multiple Myeloma

• Lymphoma (marrow involvement)

Aplastic anemia

• Myelofibrosis

• Myelodysplastic Syndrome (MDS)

• Pancytopenia

Breast cancer

• Prostate cancer

• Lung cancer (spread to bone marrow)

Tuberculosis

• Fungal infections

• Granulomatous diseases

Difference Between Bone Marrow Aspiration and Biopsy

👉 অনেক ক্ষেত্রেই Aspiration + Biopsy together করা হয় for accurate diagnosis।

How is the Procedure Performed?

The biopsy procedure usually takes 20–30 minutes.

Steps include:

1. Patient positioned comfortably

2. Local anesthesia given

3. Special biopsy needle inserted

4. Core marrow tissue obtained

5. Pressure applied to prevent bleeding

⚠️ কিছুটা pressure বা discomfort অনুভূত হতে পারে, তবে এটি সহনীয় এবং নিরাপদ।

Tests Performed on Bone Marrow Biopsy Sample

From the biopsy tissue, the following evaluations are done:

• Histopathological examination (H&E stain)

• Reticulin & fibrosis grading

• Immunohistochemistry (IHC)

• Special stains (AFB, PAS, Iron, etc.)

এই কারণে biopsy রিপোর্ট highly reliable and detailed হয়।

Interpretation of Bone Marrow Biopsy Report

Normal cellularity

• Balanced hematopoiesis

Increased or decreased marrow activity

Suggests myelofibrosis or advanced disease

Leukemia, lymphoma, or metastatic cancer

👉 রিপোর্ট সবসময় clinical findings, CBC, peripheral smear এবং aspiration report-এর সাথে মিলিয়ে ব্যাখ্যা করা হয়।

Advantages of Bone Marrow Biopsy

✔ Confirms difficult diagnoses
✔ Evaluates marrow architecture
✔ Detects fibrosis and infiltration
✔ Helps in staging and prognosis
✔ Essential for cancer management

Is Bone Marrow Biopsy Safe?

Yes, when done by trained professionals:

• Complications are rare

• Minor pain or bleeding may occur

• Widely practiced and safe procedure

When Should You Consult for Bone Marrow Biopsy?

আপনার যদি থাকে:

• Unexplained anemia

• Persistent low blood counts

• Suspected blood cancer

• Abnormal bone marrow aspiration

• Unexplained fever or weight loss

👉 তাহলে দ্রুত একজন physician / hematologist-এর পরামর্শ নিন।
