Brief Summary
This pilot study hypothesizes that hyperthermia delivered via magnetic resonance-guided focused ultrasound (MRg-FU) is technically feasible and can be safely used in combination with concurrent reirradiation and chemotherapy for the treatment of recurrent rectal cancer. Twenty recurrent rectal cancer patients who are not candidates for surgery will be recruited for hyperthermia treatment delivered via MRg-FU concurrent with reirradiation and oral chemotherapy.

Study Arms (1)
MRg-FU
EXPERIMENTALHyperthermia via magnetic resonance-guided focused ultrasound will be administered once per week for three weeks concurrent with standard radiation and chemotherapy.
Interventions
Targeted warming of the tumor via 3 weekly MR-guided ultrasound procedures. Concurrent with radiation and chemotherapy.
30.6 Gray (Gy) over 17 fractions concurrent with chemotherapy (institutional standard).
3.5 weeks concurrent with radiation therapy (institutional standard).

- Prior pelvic radiotherapy
- Target lesion visible by MR
- Target lesion accessible for MRg-FU procedure
- Target lesion maximum dimension ≤ 6cm
- Able to communicate sensation during MRg-FU treatment
You may not qualify if:
- Abdominal or pelvic surgery (excluding biopsy) ≤ 6 weeks prior to study enrolment
- Chemotherapy or other systemic anti-cancer agent ≤ 6 weeks prior to enrolment
- Previous radiotherapy ≤ 6 weeks prior to enrolment
- Recurrent tumour involves small bowel
- Unable to characterize pain
- Pregnant / Nursing woman
- Orthopaedic implant along proposed MRg-FU beam path or at site of target lesion.
- Serious cardiovascular, neurological, renal or hematological chronic disease
- Active infection
