Study Notes
Epidemiology of Cancer
- In 2023, approximately 1,958,310 new cancer cases and 609,820 deaths projected in the U.S.
- Lung cancer incidence decreased in women by 1.1% annually, significantly slower than men at 2.6% from 2015 to 2019.
- Breast and uterine corpus cancers show increasing trends; liver cancer and melanoma rates remain stable in men over 50 but are declining in younger men.
- Prostate cancer incidence rose by 3% annually from 2014 to 2019, with 99,000 additional cases reported.
Pharmacist's Role in Chemotherapy
- Pharmacists must possess extensive knowledge of antineoplastic drug pharmacology and pharmacokinetics to manage drug-induced toxicities effectively.
Characteristics of Cancer Cells
- Cancer cells grow without external growth signals, unlike normal cells which require them.
- They ignore apoptotic signals, invade surrounding tissues, and can spread throughout the body.
Benign vs. Malignant Tumors
- Benign Tumors: Non-cancerous, grow slowly, stay in one place, and typically do not recur after removal, with rare exceptions.
- Malignant Tumors: Cancerous, have larger, irregular nuclei, grow uncontrollably, invade nearby tissues, can metastasize, and may recur after removal.
Classifications of Cancer
- Carcinomas: Involve cells that cover body surfaces, including lung and breast cancers.
- Sarcomas: Arise from supportive tissues like bone and muscle.
- Lymphomas: Originate in lymph nodes and immune system tissue.
Genetic Factors in Cancer
- Key genetic "drivers" include proto-oncogenes, tumor suppressor genes, and DNA repair genes that contribute to cancer development.
Warning Signs of Cancer (C-A-U-T-I-O-N)
- Change in bowel or bladder habits
- A sore that does not heal
- Unusual bleeding or discharge
- Thickening or lump in the breast/testicles
- Indigestion or difficulty swallowing
- Changes in size/appearance of a wart/mole
- Persistent cough or hoarseness
Diagnosis of Cancer
- Early detection is crucial for improving treatment success; imaging techniques like X-rays, CT, MRI, PET scans, and ultrasounds are frequently used.
- Biopsy Techniques: Fine-needle aspiration and examination for "false feet" characteristic of cancer cells.
- Blood Tests: Used to detect tumor markers such as HCG (human chorionic gonadotropin) and PSA (prostate-specific antigen).
Staging and Work-Up
- Tumors are staged to assess disease extent and inform treatment planning; the TNM classification system is commonly used.
- TNM Classification:
- T = Tumor size and extent (T1-T4)
- N = Nodal involvement (N0-N3)
- M = Metastasis presence (M0 or M1)
Treatment Objectives for Cancer Management
- Cure: Complete removal of cancer or eradication of cancer cells (primary treatments often involve surgery).
- Adjuvant Therapy: Additional treatments such as chemotherapy, radiation, or hormone therapy to support primary treatments.
- Palliative Treatment: Focused on alleviating symptoms and side effects of treatment rather than curing the disease.
