Study Notes
Prophylaxis and Early Treatment
- Eradication of precancerous lesions is crucial, e.g., familial polyposis often requires total proctocolectomy.
- Mastectomy is a common preventive measure in high-risk patients.
Multidisciplinary Approach to Cancer Treatment
- Early cancer (loco-regional) indicates curable and operable conditions, with no evidence of distal spread.
- Radical treatment is essential, employing loco-regional modalities such as surgery and radiotherapy.
- Adjuvant systemic treatment (chemotherapy) is used when distant metastasis is a possibility.
- The number of involved lymph nodes correlates with the risk of microscopic metastasis.
Late-Stage Cancer Management
- Incurable, systemic late-stage cancer requires palliative treatment due to distant metastasis.
- Palliative care focuses on alleviating symptoms through systemic treatments like chemotherapy and hormones.
- Surgery or radiotherapy may be employed for symptom relief, with analgesics utilized for pain management.
Surgical Treatment
- Radical surgery aims to completely remove the primary tumor with a wide safety margin to avoid microscopic extensions.
- Lymph node management varies per cancer type, with removal recommended in gastrointestinal tumors when involved.
- Care must be taken to prevent spillage of malignant cells during surgery.
Advantages and Disadvantages of Surgery
- Surgery provides quick and effective treatment, often ensuring complete excision verified by histopathological examination.
- However, it can result in functional and cosmetic disabilities and is not applicable for advanced tumors.
Radiotherapy
- Can serve as an alternative to surgery or supplement it; particularly effective in lymphoma cases.
- Utilizes powerful types of radiation: teletherapy (external) and brachytherapy (internal placement of radioactive materials).
Advantages and Disadvantages of Radiotherapy
- Benefits include minimal functional impairment and the ability to eliminate microscopic extensions, suitable for patients unfit for surgery.
- Drawbacks include less sensitivity for certain tumors, potential skin burns, and a slower treatment course (5-8 weeks).
Chemotherapy
- Considered when micro metastasis is likely, used as secondary treatment in early stages or primary in late-stage cancers.
- Operates by preventing cancer cell multiplication via DNA replication interference.
Advantages and Disadvantages of Chemotherapy
- Can reach malignant cells systemically, offering cures for various cancers like lymphomas and testicular tumors.
- Associated side effects include damage to healthy cells, leading to conditions like anemia and nausea.
Hormone Therapy
- Involves hormone blocking or supplementation to manage cancer growth rates (e.g., anti-estrogens for breast cancer).
Prognosis Factors for Malignant Neoplasms
- Tumor characteristics, classified by TNM (size, lymph node involvement, metastasis), affect prognosis significantly.
- Larger tumors and involvement of numerous lymph nodes worsen outcomes; well-differentiated tumors provide a better prognosis than undifferentiated ones.
- Other factors include tumor site, type (sarcomas worse than carcinomas), age, chronic conditions, and delays in management.
Management Considerations
- Emphasizes the importance of early detection and timely treatment.
- Poor prognosis is linked to age, chronic illnesses, immunosuppressive treatments, malnutrition, and any delays in healthcare access.
