Description

Oncology emergencies are urgent medical situations that arise in cancer patients, often requiring immediate intervention. Types of Emergencies: Tumor Lysis Syndrome (TLS): Occurs due to rapid cell destruction, leading to metabolic imbalances. Hypercalcemia: Elevated calcium levels can cause confusion, dehydration, and cardiac issues. Spinal Cord Compression: Results from tumor pressure on the spinal cord, leading to neurological deficits. Superior Vena Cava Syndrome: Obstruction of blood flow in the superior vena cava, causing swelling and respiratory distress. Febrile Neutropenia: Fever in patients with low white blood cell counts, indicating possible infection. Management: Prompt recognition and treatment are critical to prevent complications and improve outcomes. Interventions may include hydration, medications, radiation, or surgical procedures depending on the emergency.

PATHOLOGY
Cancer is a significant public health issue in Kenya, with rising incidence and mortality rates. Key Statistics: Breast, cervical, and prostate cancers are the most prevalent types. Increasing cases attributed to lifestyle changes, environmental factors, and improved diagnostic capabilities. Challenges: Limited access to early detection and treatment facilities, particularly in rural areas. Inadequate healthcare infrastructure and a shortage of trained oncology professionals. Initiatives: Government and non-governmental organizations are implementing awareness campaigns and screening programs. Efforts to improve treatment access through the establishment of specialized cancer centers and palliative care services. Future Directions: Emphasis on research, prevention strategies, and enhancing healthcare systems to address the growing cancer burden.

PATHOLOGY
Cancer treatment varies based on the type, stage, and location of cancer, as well as the patient's overall health. The main treatment modalities include: 1. Surgery Purpose: Remove the tumor and surrounding tissue. Types: Curative surgery (to remove cancer completely). Palliative surgery (to relieve symptoms). 2. Radiation Therapy Purpose: Use high-energy particles or waves to destroy or damage cancer cells. Types: External beam radiation (from outside the body). Internal radiation (brachytherapy). 3. Chemotherapy Purpose: Use of drugs to kill cancer cells or stop their growth. Administration: Can be given orally, intravenously, or via injection. Side Effects: Nausea, fatigue, hair loss, etc. 4. Immunotherapy Purpose: Boost the body’s natural defenses to fight cancer. Types: Monoclonal antibodies. Immune checkpoint inhibitors. 5. Targeted Therapy Purpose: Target specific molecules involved in cancer growth and progression. Examples: Tyrosine kinase inhibitors, PARP inhibitors. 6. Hormone Therapy Purpose: Block or lower the amount of hormones in the body to slow or stop the growth of cancer. Used for: Hormone-sensitive cancers (e.g., breast and prostate cancer). 7. Stem Cell Transplant Purpose: Replace damaged bone marrow with healthy stem cells. Used for: Certain types of blood cancers (e.g., leukemia, lymphoma). Conclusion Cancer treatment is often a combination of these modalities, tailored to the individual patient's needs. Ongoing research and clinical trials continue to improve treatment options and outcomes.
