OTHERConventional Radiograph based Brachytherapy
Interventions
MRI based BT prescription will be in accordance to the GEC-ESTRO guidelines \[Intention will be to treat the whole cervix and the remaining residual tumour tissue at the primary site at the time of BT (high risk-clinical target volume) to a dose level analogue to the dose level previously prescribed for point-A\]
The standard conventional radiography based prescription will be according to Manchester system Point A and bladder \& rectum ICRU point dose constraints
Eligibility Criteria
You may qualify if:
- Cancer of the uterine cervix considered suitable for curative treatment with definitive radio-(chemo) therapy including MRI guided Brachytherapy.
- Positive biopsy showing squamous-cell carcinoma, adenocarcinoma or adeno-squamous cell carcinoma of the uterine cervix.
- Stage IIB/IIIB according to FIGO and tumor node metastasis (TNM) guidelines
- Suitable for Brachytherapy boost
- MRI of pelvis at diagnosis is performed
- MRI, Computed Tomography (CT) or Positron Emission Tomography (PET) -CT of the retroperitoneal space and abdomen at diagnosis is performed to rule out Para-aortic lymph node metastasis.
- Patient informed consent
- Pre-treatment Haemoglobin level \>10 g/dL
You may not qualify if:
- Other primary malignancies except carcinoma in situ of the cervix and basal cell carcinoma of the skin.
- Metastatic disease
- Patients with para-aortic metastatic nodes (stage IVB) to the level of L2 vertebra or further dissemination
- Previous pelvic or abdominal radiotherapy
- Previous total or partial hysterectomy
- Combination of preoperative radiotherapy with surgery
- Patients receiving BT only
- Patients receiving EBRT only
- Patients receiving neoadjuvant chemotherapy
- Contraindications to MRI
- Contraindications to BT
- Active infection or severe medical condition endangering treatment delivery.
- Pregnant, lactating or childbearing potential without adequate contraception
