• Patients should not have received radiotherapy to the target area within the preceding 12 months.
• Subject has clinically acceptable haematological, electrolyte and hepatic function as demonstrated by serum laboratory values within 14 days prior of VTP treatment:
• Absolute neutrophil count (ANC) ≥ 1500mm-3
• Platelet count ≥ 100,000mm-3
• Haemoglobin ≥ 10gdl-1
• Prothrombin time (PT) ≤ 1.5 * Upper Limit of Normal (ULN)
• Activated partial thromboplastin time (APPT) ≤ 1.5 * ULN
• Total bilirubin < 2.5 * ULN
• Aspartate aminotransferase (AST) < 3 * ULN
• Alkaline phosphatase (ALP) < 2 * ULN; unless arising from bone
• Participants has a clinically acceptable ECG
• Able (in the Investigators opinion) and willing to comply with all study requirements.
• Willing to allow his or her General Practitioner and consultant, if appropriate, to be notified of participation in the study.

Exclusion Criteria:

The participant may not enter the study if ANY of the following apply:

• Non menopausal women
• Significant hepatic impairment.
• Significant renal impairment as to mean surgical resection is unsuitable
• Clinical or radiological evidence of metastatic disease
• Subjects with tumours lying adjacent to vital structures such that VTP treatment would risk damage to these structures
• Subjects currently taking immunosuppressive medication
• Patients whose medical conditions need the following medication which have potential photosensitizing effects (tetracyclines, sulphonamides, phenothiazines, sulfonylurea hypoglycaemic agents, thiazide diuretics, griseofulvin and amiodarone (see appendix G)) if these treatments cannot be stopped or replaced by other treatments without photosensitizing properties
• Patients who have an absolute need for anticoagulant drugs or antiplatelet drugs (e.g., warfarin, aspirin), which cannot be withdrawn during the 10 days prior to the VTP procedure.
• Scheduled elective surgery or other procedures requiring general anaesthesia during the study.
• Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the study, or may influence the result of the study, or the participant's ability to participate in the study.
• Participants involved in the treatment phase of a clinical trial (observational or follow-up studies will be allowed)
• An American Society of Anaesthesiologists (ASA) score of ≥ 3
