CANCER OF THE UTERINE CERVIX: RADIOTHERAPY Radical radiotherapy: Delivered with a curative intention; for stages I-IIIB; selected cases of IVA Concurrent Chemoradiotherapy is an option for stage II and III disease Dose delivery reference points: Points A & B Post OP RT in high risk early stage disease after surgery Palliative radiotherapy
Slide 13-

CANCER OF THE UTERINE CERVIX: RADICAL RADIOTHERAPY A combination of external-beam pelvic irradiation covering the uterus, parametria and the lymphnodes and intracavitary irradiation for the central disease is used The aim is to deliver a total dose of around 80 Gy to point A
Slide 14-

CANCER OF THE UTERINE CERVIX: EXTERNAL RADIOTHERAPY Parallel pair of portals Four-field beam arrangement Special midline shields (after 20 Gy in stages I & II; after 40 Gy in stage III) 40-50 Gy in 20-25 F over 4-5 weeks
Slide 15-

CANCER OF THE UTERINE CERVIX: INTRACAVITARY RADIOTHERAPY LDR: 1 (for stage III) or 2 (for stages I & II if midline shield is used) applications of 30 Gy to point A HDR: 5 weekly applications of 7 Gy to point A (for stages I and II if midline shield is used) or 3 applications of 7 Gy to point A (for stage III) 1 – Tandem 2 – Rectal marker 3 – Marker seeds 4 – Flange 5 – Right ovoid 6 – Urinary catheter balloon 1 – Rectal marker 2 – Tandem 3 – Ovoids
Slide 16-

CANCER OF THE UTERINE CERVIX: PALLIATIVE RADIOTHERAPY In most cases of IVA and IVB 30 Gy in 10 F over 2 weeks

BREAST CANCER IN THE WORLD 1.15 million new cases Incidence increasing in most countries 470 000 deaths Half of the global burden in low- and medium-resourced countries

BREAST CONSERVING SURGERY Breast cancer screening programs Increase mass awareness Patients with earlier stages presenting to clinic Better psycho-social Adjustment BREAST CONSERVING THERAPY (BCT) Better Quality of life

RECENT ADVANCES IN RADIOTHERAPY CT simulators and Portal imaging 3DCRT IMRT IGRT Portable LA for IORT Only 20% of population has access to RT in Africa; 40 % in Asia and 50 % in Latin America

EARLY DETECTION APPROACHES Screening: mass application of screening test in asymptomatic populations at regular intervals Early clinical diagnosis: detection of early clinical stages of disease in symptomatic or high-risk subjects
