Although most malignant lymphadenopathy in the neck represent lymphomas or metastases from head and neck primary tumors, occasionally, metastatic disease from remote, usually infraclavicular, sites presents as cervical lymphadenopathy with or without an obvious primary tumor. In general, these tumors metastasize to supraclavicular lymph nodes, but occasionally may present at an isolated higher neck level. A search for the primary tumor includes information gained by histology, immunohistochemistry, and evaluation of molecular markers that may be unique to the primary tumor site. In addition, 18F-fluoro-2-deoxyglocose positron emission tomography combined with CT (FDG-PET/CT) has greatly improved the ability to detect the location of an unknown primary tumor, particularly when in a remote location. Although cervical metastatic disease from a remote primary site is often incurable, there are situations in which meaningful survival can be achieved with appropriate local treatment. Management is quite complex and requires a truly multidisciplinary approach. © 2015 Wiley Periodicals, Inc. Head Neck 38: E2374-E2385, 2016.

Cervical lymph node metastases from remote primary tumor sites

In testicular germ cell tumour (GCT), imaging plays a central role in assessment of tumour bulk, sites of metastases, monitoring response to therapy, surgical planning and accurate assessment of disease at relapse. The primary modality used for imaging patients with GCT is computed tomography (CT) but plain film radiography, ultrasound, magnetic resonance imaging (MRI) and positron emission tomography (PET) may all have roles to play. This article reviews the role of imaging of testicular germ cell tumours.

No Role for Routine Chest Radiography in Stage I Seminoma Surveillance

Tricuspid valve metastasis from testicular carcinoma: a case report and review of the literature.

BACKGROUND. This study evaluated the cost-effectiveness of posttreatment surveillance after radiation therapy for early stage seminoma. METHODS. From 1988-1995, 47 patients with Stage I, and 11 patients with Stage II seminoma (based on the Royal Marsden staging system) received paraaortic and pelvic lymph node radiation after radical orchiectomy. Patient records were reviewed and patients surveyed to determine the tests ordered for posttreatment surveillance. RESULTS. With a median follow-up of 55 months, there were 2 recurrences among the 58 patients. Eight-year actuarial disease free survival was 93%, with 100% overall survival. Information concerning follow-up screening was available for 56 patients. The follow-up tests ordered included 842 physical examinations, 815 chest X-rays, 839 serum markers, 250 computerized tomography scans, and 112 abdominal plain films. The total cost of these examinations according to 1996 private sector charges and 1996 Medicare reimbursement rates, respectively, was $602,673.01 (average $10,762.02 per patient) and $282,746.52 (average $5049.05 per patient). The two patients who experienced recurrence were diagnosed independently of their posttreatment screening program. One patient recurred 7.5 months after his original diagnosis with an isolated spinal cord compression. The second patient had a mediastinum recurrence > 6 years after treatment. At last follow-up, both patients were disease free after salvage treatment. CONCLUSIONS. Patients with early stage seminoma treated with orchiectomy and radiation have excellent disease free survival rates. The cost of the surveillance program studied does not appear to be justifiable.
