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.
