Brief Summary

Worldwide, breast cancer (BC) is the most frequent type of cancer in women yet, it is associated with relatively lower mortality rates, as it ranks fifth in cancer-related deaths overall, which is attributed to evolution in the treatment of recurrent and metastatic lesions, especially when these lesions were detected early . BC recurrence can occur even 15 years after primary treatment.

Outcome Measures

Primary Outcomes (1)

  • identification of recurrence

    correlation between PET/CT parameters and the serum level of tumour markers in suspected recurrent BC as well as finding the best cut-off value of tumor markers that can be used in the identification of recurrence

    2 years

Study Arms (1)

Recurrent breast cancer patients with elevated tumor markers

PET/CT is the functional imaging tool that can measure increased glucose metabolism in cancer cells by using 18F-FDG. Its ability to identify tumor recurrence before detection of morphologic changes in conventional imaging reflecting its importance in detecting BC recurrence in asymptomatic patients with high tumor markers and negative results of radiological imaging. 18F-FDG PET/CT is frequently used for BC evaluation. However, data on its value in evaluating BC recurrence in patients with elevated tumor markers are limited and unclear

Diagnostic Test: PET/CT

Interventions

PET/CTDIAGNOSTIC_TEST

Patients with previous breast cancer, already treated and with clinical or biochemical suspicion of disease relapse. All patients will underwent 18F-fluorodeoxyglucose (FDG) PET/CT. In all patients, the value of CA 15.3 was compared to PET/CT. The final diagnosis of relapse will be derived from histopathological sampling As much as possible or radiological follow up for at least 6 months will be compared with PET/CT results.
