Aromatase enzyme inhibitors in TTT of **Breast Cancer** - Drugs
- (Aminoglute themide) - (Femara/anastrazol)
26
Aromatase enzyme inhibitors in TTT of **Breast Cancer** - Mechanism
27
Aromatase enzyme inhibitors in TTT of **Breast Cancer** - Indications
- Post-menopausal - Low grade - HR-positive - HER2 -ve disease
28
Hormonal Therapy in TTT of **Breast Cancer** - Protocols acc to age
**Pre-menopausal:** Tamoxifen then LHRH agonists then oophorectomy **Post-menopausal:** Aromatase Inhibitors then Tamoxifen then progestagens
29
Hormonal Therapy in TTT of **Breast Cancer** - SERD
Fulvestrant
30
Radiotherapy in **Breast Cancer**
31
Radiotherapy in **Breast Cancer** - Techniques
- **External radiation:** 5000 rad 5 days/week over 5 weeks (25 sessions) - **Partial breast irradiation (PBI):** if negative axilla
32
Radiotherapy in **Breast Cancer** - Indications
▪ All BCS ▪ Post mastectomy - T3 (1ry tumor > 5 cm) - Node + (>4 LN ) - +ve safety margin or <1mm
33
Target Therapy in **Breast Cancer** - Indications
Her2/neu +ve
34

Herceptin “Trastuzumab”, Pertuzumab (Perjeta)
35
ImmunoTherapy in **Breast Cancer** - Indications
high risk TNBC with chemotherapy
36
ImmunoTherapy in **Breast Cancer** - Examples
Pembrolizumab
37
Adjuvant bisphosphonates in **Breast Cancer** - Indications
bone stabilizer and risk reduction of mets
38
Adjuvant bisphosphonates in **Breast Cancer** - Examples
Zoledronate “Zometta”
39
Pathological complete Response - Def
Absence of invasive disease in breast & LN
40
**Pathological complete Response** - Incidence
41
**Pathological complete Response** - US Guided Clipping
- US guided Clipping is used before receiving Neoadjuvant to help localize the tumor site after complete response to facilitate BCS
42
TTT of **Stage IV Breast Cancer**
43
TTT of **Stage IV Breast Cancer** - Systemic
As before + - CD4/6 inhibitors - mTor inhibitors - PARP inhibitors - Immunotherapy
44
TTT of **Stage IV Breast Cancer** - Palliative
▪ Toilet mastectomy ▪ Laminectomy or vertebroplasty -----> Bone metastasis ▪ Pleurodesis ----> pleural effusion
45
Bernard Fissure’s theory
**Breast cancer is a systemic disease from the start, as it spreads so early by blood micrometastases**
