106 Background: Some patients with lymph node metastases experience prolonged survival following radical prostatectomy. The purpose of this study was to determine the outcome of patients with clinically suspicious lymph nodes on preoperative imaging who underwent radical prostatectomy and lymphadenectomy. Methods: Patients with lymph node metastases diagnosed during radical prostatectomy from 1988-2003 were reviewed. Patients with preoperative CT or MRI images were included in the study. Radiology reports were reviewed to determine if patients had clinically suspicious lymphadenopathy (cN+). For all analyses, patients with cN+ were compared to those with clinically negative nodes (cN−). Results: Preoperative imaging was available in 202 men with lymph node metastasis at the time of prostatectomy. Of these 17% (34/202) were cN+. None had pre-operative lymph node biopsy and none had abandoned prostatectomy. At a median follow-up of 11.1 years, PSA recurrence occurred in 50% (17/34) and 49% (82/186), local recurrence in 18% (6/34) and 13% (22/186) and systemic progression in 32% (11/34) and 24% (40/186) of patients with cN+ and cN-, respectively. On multivariate analysis, cN+ was not associated with increased risk of death (HR 1.66, p=0.1). Conclusions: cN+ patients undergoing surgical therapy for prostate cancer may experience similar outcomes to cN− patients. The presence of clinically suspicious lymph nodes on preoperative imaging should not be an absolute contraindication for surgical therapy. No significant financial relationships to disclose.

AbstractObjective:To investigate the performance of indirect computed tomography lymphography with iopamidol for detecting cervical lymph node metastases in a tongue VX2 carcinoma model.Materials and methods:A metastatic cervical lymph node model was created by implanting VX2 carcinoma suspension into the tongue submucosa of 21 rabbits. Computed tomography images were obtained 1, 3, 5, 10, 15 and 20 minutes after iopamidol injection, on days 11, 14, 21 (six rabbits each) and 28 (three rabbits) after carcinoma transplantation. Computed tomography lymphography was performed, and lymph node filling defects and enhancement characteristics evaluated.Results:Indirect computed tomography lymphography revealed bilateral enhancement of cervical lymph nodes in all animals, except for one animal imaged on day 28. There was significantly slower evacuation of contrast in metastatic than non-metastatic nodes. A total of 41 enhanced lymph nodes displayed an oval or round shape, or local filling defects. One lymph node with an oval shape was metastatic (one of 11, 9.1 per cent), while 21 nodes with filling defects were metastatic (21/30, 70 per cent). The sensitivity, specificity, accuracy, and positive and negative predictive values when using a filling defect diameter of 1.5 mm as a diagnostic criterion were 86.4, 78.9, 82.9, 82.6 and 83.3 per cent, respectively.Conclusion:When using indirect computed tomography lymphography to detect metastatic lymph nodes, filling defects and slow evacuation of contrast agent are important diagnostic features.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the breast and the brain reside the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in humans with metastatic breast cancer. We found that collagen type XVI alpha 1 chain, COL16A1, was among the genes whose expression was most different in the lymph node metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. COL16A1 mRNA was present at decreased quantities in lymph node metastases as compared to primary tumors of the breast. Importantly, expression of COL16A1 in primary tumors of the breast was correlated with patient overall survival, in lymph node negative patients but not in lymph node positive patients. Modulation of COL16A1 expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph nodes and the brain in humans with metastatic breast cancer.

We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in humans with metastatic breast cancer. We found that teashirt zinc finger homeobox 3, TSHZ3, was among the genes whose expression was most different in the lymph node metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Analysis of a separate microarray dataset revealed that TSHZ3 was also differentially expressed in brain metastatic tissues. TSHZ3 mRNA was present at decreased quantities in lymph node metastases as compared to primary tumors of the breast. Importantly, expression of TSHZ3 in primary tumors of the breast was correlated with patient post-progression survival, in lymph node positive patients but not in lymph node negative patients. Modulation of TSHZ3 expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph nodes and the brain in humans with metastatic breast cancer.
