Non-Hodgkin Lymphoma Cancer from Diagnosis to Treatment


What Is Non-Hodgkin Lymphoma?

Non-Hodgkin Lymphoma is a cancer that starts in the lymphatic system, part of the immune system that helps fight infections.

It occurs when lymphocytes | B-cells or T-cells | grow and multiply abnormally, forming tumors in lymph nodes or other organs such as the spleen, bone marrow, or intestines.

Unlike Hodgkin Lymphoma, NHL does not contain Reed - Sternberg cells and includes many different subtypes - some slow-growing | indolent | and others fast-growing | aggressive.


1. Early Signs and Symptoms

Painless swollen lymph nodes
Unexplained weight loss
Night sweats and fever
Persistent fatigue
Shortness of breath or chest pain
Abdominal pain or swelling
Loss of appetite
Frequent infections


2. Causes and Risk Factors
The exact cause is unknown, but risk factors include

Weakened immune system
Autoimmune diseases
Family history of lymphoma
Exposure to certain chemicals

Infections such as
Epstein-Barr virus
Helicobacter pylori
Hepatitis C virus


3. Diagnostic Procedure

Physical Examination
Checking for enlarged lymph nodes, spleen, or liver.

Blood Tests
To assess blood cell counts and organ function.

Lymph Node Biopsy
A tissue sample is examined under a microscope to confirm NHL and determine the subtype.

Imaging Tests
CT scan, MRI, or PET scan to locate tumors and assess spread.

Bone Marrow Aspiration and Biopsy
Determines if lymphoma has reached the bone marrow.

Molecular and Immunophenotyping Tests
Identify whether the lymphoma arises from B-cells or T-cells.


4. Types and Staging

B-cell lymphomas
Diffuse Large B-Cell Lymphoma, Follicular Lymphoma, Burkitt Lymphoma.

T-cell lymphomas
Peripheral T-Cell Lymphoma, Anaplastic Large Cell Lymphoma.

Stage I - One lymph node region or one organ.

Stage II - Two or more areas on the same side of the diaphragm.

Stage III - Affected nodes on both sides of the diaphragm.

Stage IV - Cancer spread to bone marrow, liver, or other organs.

Each stage is also classified as:

A - Without B symptoms.
B - With B symptoms | fever, night sweats, weight loss.


5. Treatment Options

Chemotherapy

CHOP regimen:
Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone.
Often combined with immunotherapy.

Immunotherapy

Rituximab | Rituxan:
Monoclonal antibody targeting CD20 on B-cells.

Other options:
Obinutuzumab, Ofatumumab.

Targeted Therapy

Ibrutinib, Acalabrutinib:
Block cancer cell signaling.

Lenalidomide, Idelalisib:
Used for relapsed/refractory cases.

Radiation Therapy

For localized or early-stage disease.
Can also shrink tumors causing pressure or pain.

Stem Cell Transplant

Used when NHL relapses after standard treatment.
Autologous | patient’s own cells | or Allogeneic | donor cells.

CAR T-Cell Therapy

A cutting-edge option for advanced or recurrent B-cell lymphomas.
Patient’s T-cells are modified to attack lymphoma cells.


6. Preferred Nutrition for Patients

Protein-rich foods:
fish, eggs, poultry, lentils.

Fruits & vegetables:
spinach, oranges, berries, tomatoes.

Whole grains:
oats, brown rice, whole wheat bread.

Hydration:
water, soups, and fresh juices | pasteurized.

Healthy fats:
olive oil, nuts, seeds, avocado.



7. Follow-Up

Indolent lymphomas progress slowly and may be managed for many years.

Aggressive lymphomas respond well to prompt treatment and can be cured in many cases.

Regular follow-up with blood tests and imaging is essential to monitor remission or recurrence.
