Renal cell carcinoma presenting with metastases to pulmonary hilar nodes

Neocarzinostatin-induced complete regression of metastatic renal cell carcinoma

We report a case of histologically confirmed pulmonary and hilar metastases from renal cell carcinoma. Complete response to neocarzinostatin has been maintained for 18 months.

Metastatic renal cell carcinoma simulating sarcoidosis. Analysis of 12 patients with bilateral hilar lymphadenopathy

Case summaries of four patients with bilateral hilar lymphadenopathy (BHL) caused by metastatic renal cell carcinoma are presented, and these and eight similar cases from the literature are analyzed. In nine patients, sarcoidosis was the provisional clinical diagnosis, but four of these patients had a past history of renal cell carcinoma. In the remaining five patients, a distinction from sarcoidosis could not be made by history, physical examination, and chest roentgenogram. This underscores the need for tissue confirmation in the diagnosis of sarcoidosis and alerts the physician to consider metastatic renal cell carcinoma in the differential diagnosis of BHL.

Metastatic processes and a potential indication of treatment for metastatic lesions of renal adenocarcinoma

Renal adenocarcinoma findings from 307 autopsied cases with metastasis to 1 and 2 organs were investigated concerning the mode of metastasis. The lung was the most frequent site of metastasis to 1 organ, although the frequency was rather low (30 per cent), followed by bones (over-all), lymph nodes (over-all) and brain, and involving frequently the thoracic spine and retroperitoneal lymph nodes. In patients with metastases to 2 organs a significant correlation was found between the pulmonary-tracheal lymph nodes and those to the lungs. Potential indications for treatment of metastatic lesions were 1) lymphadenectomy and/or radiation therapy for the retroperitoneal and para-aortic lymph nodes and 2) resection of metastatic lesions in the lungs combined with lymphadenectomy and/or radiation therapy for the pulmonary-tracheal lymph nodes. In patients without lung metastasis lymphadenectomy and/or radiation therapy for the pulmonary-tracheal lymph nodes is not always necessary.
