The study will be conducted as an open label, single-dose, explorative study with patients with histologically proven cancer and, preferably, tumor positive lesions in previously performed nuclear medicine imaging examinations.

The investigational drug will be given as a single administration in a dose of \

Inclusion Criteria:

• Males/females >/= 18 years
• Patients with a diagnosis of primary prostate cancer (biopsy proven) and scheduled for radical prostatectomy or patients with prostate tumor recurrence (Patients with advanced tumor disease and a high likelihood to display lymph node metastasis are to be preferably included.)
• ECOG (Eastern Cooperative Oncology Group) performance status of 0-2, determined within one week prior to treatment with BAY94-9392
• Patient had an [18F]-fluorodeoxyglucose (FDG) PET/CT for detection, or staging, or restaging, or therapy response assessment that still showed tumor mass with high certainty for a cancer such as melanoma, or colorectal cancer, or head & neck cancer for which FDG-PET/CT is used in clinical routine, and the primary cancer disease is histologically confirmed. In case of recurrent disease confirmation of the primary tumor is sufficient
• No clinically relevant deviations in renal function as determined by Cockcroft and Gault method using serum creatinine at screening.

Exclusion Criteria:

• Concurrent severe and/or uncontrolled and/or unstable medical disease other than cancer or inflammation (e.g. poorly controlled diabetes, congestive heart failure, myocardial infarction within 12 months prior to planned injection of BAY94-9392, unstable and uncontrolled hypertension, chronic renal or hepatic disease, severe pulmonary disease) which could compromise participation in the study
• Known sensitivity to the study drug or components of the preparation
• Previous treatment with BAY94-9392 in this study
