Lymphoma

Definition of Lymphoma
- Cancers of lymphocyte cells, leading to tumors in lymph nodes, which are crucial for antibody production and fighting infections.
- Can metastasize to various organs.
- Types of lymphoma include:
  - Hodgkin’s Lymphoma (HL)
  - Non-Hodgkin’s Lymphoma (NHL)

Characteristics
- Fairly rare, with peaks in ages:
  - Teens and young adults
  - Adults in their 50s and 60s
- Causes: Possible links to viral infections and exposure to chemicals.
- Typically starts in a single node or chain of nodes containing Reed-Sternberg cells.
- Pattern of spread: Predictable progression from one lymph node group to another.
- Survival Rates: Approximately 86% at 5 years.
Symptoms
- Often begins with a painless enlarged lymph node, commonly in:
  - Cervical area
  - Supraclavicular area
  - Mediastinal region
- Other symptoms include:
  - Pruritus (unknown cause)
  - B-symptoms (fever, drenching night sweats, unintentional weight loss, fatigue)

Impact on Organs
- Lymphoma cells can invade various organs, causing:
  - Abdomen: Compression of ureters and kidneys, nausea, anorexia, weight loss
  - Lungs: Cough, respiratory distress
  - Mediastinal area: Compression of trachea leading to dyspnea
  - Liver: Jaundice
  - Spleen: Abdominal pain
  - Bone: Bone pain
Diagnostics
- Biopsy for Reed-Sternberg cells
- Physical examination for B symptoms, palpable nodes, and enlarged organs
- Imaging: CT scan, chest X-ray (CXR)
- Laboratory tests: CBC, platelet count, ESR, liver function tests (LFT), renal studies
Treatment Options
- Chemotherapy: Increased intensity yields better cure rates but carries risks of toxicity.
- Radiation therapy: Used alone or in combination with chemotherapy.
- Hematopoietic Stem Cell Transplant (HSCT): Considered in certain scenarios.
- Long-term risks include secondary malignancies and increased cardiovascular disease risk due to anterior chest radiation.

Characteristics
- Affects both men and women, with a median diagnosis age of 66.
- Comprises various cancers from lymphocytes, with differences in morphology:
  - 85% are malignant B lymphocytes
  - 15% are malignant T lymphocytes
Symptoms
- Variable symptoms due to the diversity of cell types:
  - Lymphadenopathy (common symptom)
  - B-symptoms (1/3 of patients experience)
  - Other symptoms may include:
    - Chest pain, pressure
    - Chills
    - Drenching night sweats
    - Fatigue
    - Shortness of breath or cough
    - Unexplained weight loss
Diagnostics
- Staging: Extensive testing essential for tailored treatment (NHL has over 60 subtypes).
- Diagnosis often delayed until nodes are enlarged.
- Utilization of tests like:
  - CT, PET scans
  - Bone marrow biopsy
  - CSF analysis
  - Histological examination to identify cell type
Treatment Options
- Dependent on patient’s tolerance and other health conditions.
- Early-stage: May involve localized radiation.
- Aggressive cases may require combination chemotherapy, with intrathecal chemotherapy if CNS is involved.

Monitoring for Infection
- Vital signs monitoring and infection signs (fever)
- Daily CBC inspection; inspect IV sites, wounds
- Private room, strict hand hygiene, limited visitation
Bleeding Management
- Monitoring labs for thrombocytopenia and coagulation status
- Observe for signs of bleeding; use soft toothbrushes, electric razors
Care for Mucositis
- Daily oral assessments; avoid irritants
- Suggest saline mouth rinses; provide anesthetics for discomfort
Nutritional Intake Improvement
- Oral care pre-and post-meals; ensure nutrient-dense, soft foods
- Daily weight and caloric assessments; may need parenteral nutrition
Pain Management
- Regular assessment with pain scale, early administration of analgesics
- Use of distraction techniques in children
Addressing Fatigue
- Encourage structured rest and light exercise; nutritional support
Emotional Support
- Support for patients and families regarding changes in body image;
- Encourage participation in decision-making and express feelings.
