Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be intravenously administered 1.8-2.2MBq/kg (maximum 220MBq) of [68Ga]gallium 2,2'-(7-(4-((1-carboxy-4-((1-((carboxymethyl)amino)-3-((2-((4-(dihydroxyarsaneyl)phenyl)amino)-2-oxoethyl)thio)-1-oxopropan-2-yl)amino)-4-oxobutyl)amino)-1-carboxylato-4-oxobutyl)-1,4,7-triazonane-1,4-diyl)diacetate (68Ga Cell Death Indicator [68Ga-CDI]) on two occasions, once within 14 days prior to commencing treatment and the second between day 15 and day 20 (inclusive) after commencement of treatment (chemoradiotherapy in the case of oesophageal / gastro-oesophageal and rectal carcinoma and chemotherapy in the case of breast carcinoma and lymphoma).

One hour following each 68Ga-CDI administration, participants will undergo a positron emission tomography (PET) scan where they will lie still on a scanning bed (breathing normally). The scan will take approximately 30 minutes.

68Ga-CDI will be administered by a nuclear medicine specialist or medical radiation scientist. 68Ga-CDI administration and PET scannning will occur at the Prince of Wales Hospital (Randwick, NSW), St George Hospital (Kogarah, NSW), St. Vincent's Hospital (Darlinghurst, NSW), Concord Hospital (Concord, NSW), and Westmead Hospital (Westmead, NSW).

Statistical methods / analysis
The statistical analysis of the 68Ga-CDI PET scans will assess tumour and normal tissue SUVmax, SUVmean before and following commencement of treatment as well as the change between pre-treatment and following commencement of treatment.

To determine if there is a significant change in the mean values pre-treatment and following commencement of treatment for tumour and normal tissues a paired t-test will be used.

To further determine the clinical significance of absolute and change in CDI uptake, correlation with subsequent clinical outcome will be undertaken. For oesophageal/GOJ adenocarcinoma, rectal adenocarcinoma and breast carcinoma, pathological response on the surgical specimen will be used as the reference, and for DLBCL and grade 3 FL the Deauville score of end of treatment FDG PET CT will be used as the reference standard.
