Multiple primary synchronous malignant tumors

BACKGROUND: Patients with primary multiple malignancies are progressively increasing due to prolonged survival of cancer patients and to the advances in diagnostic techniques and therapeutic options. CASE PRESENTATION: Here we present a 66 year-old caucasian patient with four synchronous primary malignant tumors affecting the lung, oropharynx, large bowel and prostate gland, respectively, treated with multidisciplinary approach. CONCLUSIONS: The increased incidence of multiple malignant tumors is a real challenge to the clinician and clinical attention should be made to avoid a misdiagnosis. In addition an early diagnosis is essential to achieve a radical treatment. We believe that the treatment modality should be carefully made and tailored on the individual patient suffering from this disease.
