Oncological management Flashcards
Non-surgical management types
- Cytotoxic chemotherapy (kills all cells, doesn’t differentiate well between cancerous/non-cancerous cells)
- RT (done by clinical oncologists, not medical oncologists)
- Targeted therapies
- Immunotherapy (risk of inducing autoimmune reactions)
- Endocrine
- Bisphosphonates (breast cancer - reduce recurrence; also treats hyperCa2+ and bone mets)
- Supportive care
Prognosis of different cancers.
a) Good
b) Bad
a) Testicular, prostate, breast, melanoma (note: even if metastatic, may have good treatments that mean they live for years)
b) Pancreas, UGI, lung, brain, thyroid?
Selecting candidates for treatment
a) Cancer features
b) Performance status
a) TNM, biology,
b) WHO grades 0-5 (>2 risks probably outweigh benefit)
Haematological (non-solid) cancers - managed by…?
Haematologists, not oncologists
Chemotherapy types
- Radical (e.g. metastatic germ cell)
- Adjuvant (after surgery) and neoadjuvant (before surgery) - reduce risk of local/distant relapse
- Chemoradiotherapy (potentiates effect of RT; used in head and neck, anorectal, bladder, cervix; e.g. cisplatin)
- Palliative - may improve QoL by reducing symptoms
Investigations
History and examination
Imaging of mass
Staging CT (generally CAP)
Biopsy and grading
Breast cancer drug management
- ER positive: Pre-menopausal: tamoxifen Post-menopausal: aromatase inbibtor (anastrazole) - HER positive: herceptin - Other?
Radiotherapy
- Stereotactic (gamma knife) - brain primaries and secondaries
- Proton therapy
Endocrine treatment
- Tamoxifen - selective oestrogen receptor modulator - breast Ca (pre-menopausal)
- Aromatase inhibitors - breast Ca (post-menopausal only)
- GnRH analogues - prostate Ca
Targeted therapies
- Tyrosine kinase inhibitors - given in …?
- CDK4/6 inhibitors - given in breast Ca with aromatase inhibitors
Radiotherapy: side effects
a) Common skin problems (and management)
b) Other common issues
c) Site-specific: i) Head and neck, ii) Chest, iii) Abdo/ Pelvis
a) Acute radiation dermatitis: range from erythema and itching to blistering and ulceration. Manage with topical therapies
b) Fatigue
c) i) N/V, dry mouth, mouth sores, metallic taste, jaw stiff
ii) Breast tenderness, SOB, radiation pneumonitis/ fibrosis
iii) N/V, diarrhoea, bladder dysfunction, rectal bleeding, sexual dysfunction and infertility
Chemotherapy: side effects
think ‘loss’
- Loss of hair
- Loss of appetite and weight loss
- Loss of muscle strength/ fatigue
- Loss of cognitive function
- Loss from back passage (diarrhoea)
- Beau’s lines in nails
RT/chemo: late effects
- Second cancer (esp. RT - cause skin cancer/thyroid)
- Chest: HTN, CCF, arrhythmias, lung fibrosis
- Endocrine: infertility, hypopituitarism, sexual dysfunction
- Psychological: depression, anxiety, etc.
Most common treatment-related reasons for admission in oncology patients
- Suspected neutropenic sepsis
- Infection, not neutropenic
- Nausea and vomiting
- Diarrhoea
- Electrolyte imbalance (including tumour lysis)
- Head and neck radiotherapy symptom management
Most common non-treatment related reasons for admission in oncology patients
- Pain and symptom management
- Oncology emergency (collapse)
- Disease related symptoms (e.g. jaundice, hypercalcaemia)
- Pulmonary embolus, DVT
