Study Notes

Cancer Therapeutics

  •  Cancer is a broad term, encompassing over 200 different types. Each type requires unique diagnosis and treatment.

  •  Discussions about cancer can evoke strong emotions or memories; approaching these topics with sensitivity is crucial.

Lecture Outline

  • Lecture 1 (Today): Diagnosis and treatment modalities for cancer.
  • Lecture 2: Mechanism of action for common chemotherapy drugs and common side effects for patients.
  • Lecture 3: Radiotherapy and nuclear pharmacy.

Patient's Journey

  • Earlier diagnosis and treatment lead to better patient outcomes. Delayed treatment increases complications and healthcare costs.
  • The NHS Faster Diagnosis Standard aims for diagnosis within 28 days of referral by a GP and treatment within 62 days.
  • A specific pathway exists for patients presenting with non-specific symptoms. These patients require more in-depth diagnosis via blood tests and symptom-specific tests (CT, endoscopy), which are needed for triage.

Diagnosis of Cancer

  • Cancer diagnosis varies significantly depending on the type of cancer (solid vs. blood cancers).
  • A physical exam might not be suitable for diagnosing leukaemia.
  • Common diagnostic tests include imaging scans (CT, PET), laboratory tests for tumor biomarkers, and biopsies.

Pharmacist's Role

  • Pharmacists play a crucial role in cancer diagnosis.
  • Pharmacist duties include medication management, patient education and collaboration with the wider healthcare team.
  • Recognizing red flag symptoms that necessitate GP referral is part of the pharmacist's role. (including organ-specific symptoms like blood in the urine, persistent cough, and unexplained lumps.)
  • Red flag examples for all ages - unexplained lump in neck; unexplained ulceration in mouth (lasting >3 weeks); persistent hoarseness (lasting >4 weeks). Additional concerns for those aged 45+ with these symptoms, and repeat purchase of throat lozenges or medication.

Management: Aims & Strategy

  • The primary goals for cancer management are prevention, early detection, and cure.

  • Prevention includes vaccination and the reduction of risk factors.

  • Early detection focuses on public health initiatives and screening programs (e.g., bowel, breast, and cervical cancer screenings).

  • Cure aims for the total eradication of cancer cells.

  • The hierarchy of aims in cancer management includes curing cancer, remission/mitigation, symptom management/palliation, and terminal care.

Cancer Treatment

  • A realistic assessment of the cancer management program is essential before initiating treatment.

  • The hierarchy of aims includes:

  • Cure: eradication of the tumor and metastasis.

  • Remission/Mitigation: significant reduction in tumour load, leading to increased survival.

  • Symptomatic/Palliation: treatment of complications and relief of symptoms.

  • Terminal Care: improving quality of life and optimizing symptom control.

Modes of Therapy

  • Treatment methods depend heavily on the precise cancer type being treated.
  • Common modes include: surgery, radiotherapy, and drug therapy (cytotoxic, hormone, and immunotherapy).
  • Adjuvant therapies often complement initial treatment approaches.
  • Neoadjuvant therapies aim to debulk or downstage tumors before definitive treatment.

Chemotherapy

  •  In cancer treatment, chemotherapy aims to kill rapidly dividing cells, including normal cells (this is why there are side effects).
  • The agents are not inherently tumor-specific.
  • Chemotherapy is a major cancer treatment method.
  • Factors influencing treatment decisions include empirical evidence and practical considerations.
  • Chemotherapy is often used in combination, rather than as a single-agent therapy.
  • Timing of treatment, combination of drugs, and the shortest possible time between treatments are important.
  • Remission or a measurable response to treatment can aid in ongoing treatment decisions.

Terminology

  • Remission: lack of detectable cancer cells in the body, even if small numbers remain, not actively growing.
  • Palliation: relief of tumor symptoms and prolongation of life when a cure is not possible, this can improve quality of life.

Key Diagnostic Factors

  • The variety of cancer symptoms can often be non-specific (fatigue).
  • The diagnosis process depends on specialist teams to pinpoint causes.
  • Specific diagnostic tools include imaging (CT, PET scans), lab tests to find tumor biomarkers, and biopsies to confirm or rule out cancer.

Quiz

  • A quiz link is provided.

Chemotherapy Regimens

  • Regimens vary by cancer type.
  • Regimens detail: the indication (disease), drug and doses, investigations, and concurrent medications. Dose modifications may also be needed.

Supportive Medications

  •  Anti-emetics are routinely given to mitigate nausea and vomiting, the side effects of chemotherapy.
  • Pre- and post-hydration are crucial for patients undergoing cisplatin chemotherapy to maintain kidney function and flush the medicine out of the body.

Other

  • Combination therapy, compared to single-agent therapy, often leads to greater remission, but also comes with more significant side effects.
  • Different cancer types may require adjustments to drug dosages.
