Study Notes

Benign and Malignant Neoplasms

Benign Neoplasms: Non-cancerous growths that do not spread to other parts of the body.
Malignant Neoplasms: Cancerous tumors that invade surrounding tissues and can metastasize to distant sites.

Systemic Effects of Malignant Tumors

Weight Loss and Cachexia: Caused by increased metabolic demand and altered metabolism leading to severe tissue wasting.
Anemia: Results from chronic bleeding, bone marrow depression, and decreased food intake.
Bleeding: Occurs due to erosion of blood vessels and tissue ulceration.
Infections: Related to bone marrow suppression and impaired immune responses.
Paraneoplastic Syndromes: Tumor cells release substances affecting various bodily functions and can lead to hyper-coagulation.
Effusions: Inflammation results in fluid accumulation in body cavities.

Cancer Invasion and Metastasis

Metastasis: The spread of cancer cells to distant organs, requiring cells to survive, proliferate, and find a compatible environment.
Invasion: First step in metastasis, where cancer spreads locally, often through lymphatic and blood systems.

Pathways of Spread

Dissemination occurs through lymphatic, hematogenous, or transcoelomic pathways.

Tumor Classification Systems

Anatomic Site Classification: Classifies tumors by their tissue of origin and behavior (e.g., carcinomas, sarcomas).
Histologic Classification: Evaluates abnormal cells based on their appearance and differentiation (Grades I-IV).
Clinical Staging: Determines the extent of disease spread, from Stage 0 (in situ) to Stage IV (metastatic).

Benign Brain Tumors

Statistics: Approximately 55,000 Canadians live with a brain tumor; 27 new diagnoses daily.
Types: Primary tumors arise from brain tissues; secondary tumors stem from metastasis.
Meningioma: Represents 54% of benign brain tumors, causing symptoms from local mass effects or seizures.

Meningioma – Diagnosis and Treatment

Diagnosis: Confirmed via MRI; CT scans used for accessibility. Asymptomatic cases may require observation.
Treatment Options: Symptomatic cases require surgical resection; radiotherapy may be adjunctive.

Colorectal Cancer

Requires screening starting at age 50 or earlier based on family history.
Diagnosis: Involves physical exams, stool tests, colonoscopy, and imaging studies.
Treatment: Options depend on staging and may include surgery, chemotherapy, or radiation.

Malignant Melanoma

Most aggressive skin cancer, with rising incidence rates.
Typically occurs due to UV radiation exposure (natural or artificial).
Types: Includes superficial spread melanoma (SSM), nodular melanoma (NM), lentigo maligna melanoma (LMM), and acral lentiginous melanoma (ALM).
Clinical Features: Changes in moles (ABCDEs: Asymmetry, Border, Color, Diameter, Evolving).

Osteosarcoma

Most common bone cancer in children and young adults; peak incidence is between ages 10-25.
Characterized by rapid growth and frequent metastasis, often to lungs.
Symptoms: Include bone pain, swelling, and fractures.
Treatment: Can involve surgical resection or amputation, with chemotherapy as an adjunct.

Nursing Assessments and Goals of Care

Monitor neurological function and pain levels for tumor patients.
Goals include maintaining normal intracranial pressure (ICP) and optimizing neurological function.
Provide education on disease progression and emotional support for patients and families.
