Stage II seminoma is divided into bulky and nonbulky disease for treatment planning and expression of prognosis. Bulky disease is generally defined as tumors larger than 5 cm on a computed tomographic (CT) scan (i.e., stage IIC disease). Nonbulky disease can be further subdivided into stage IIA, meaning no lymph node mass larger than 2 cm, and stage IIB, meaning a lymph node mass between 2 cm and 5 cm.
This complementary and alternative medicine (CAM) information summary provides an overview of the use of Cannabis and its components as a treatment for people with cancer -related symptoms caused by the disease itself or its treatment.
This summary contains the following key information:
Cannabis has been used for medicinal purposes for thousands of years.
By federal law, the possession of Cannabis, also known as marijuana, is illegal in the United States; however, a growing number of states...
Nonbulky stage II disease has a cure rate of about 90% to 95% with radiation alone at doses of 30 Gy to 36 Gy,[1,2,3,4] and most relapsing patients can be cured with chemotherapy. Cure rates are slightly higher for patients with stage IIA disease than for those with IIB disease, but the figures are within the range given above. Risk factors for relapse include multiple enlarged nodes.
Results for patients with stage IIC disease have been less favorable. For example, one institution reported that 9 of 16 (56%) stage IIC patients relapsed following radiation therapy, while relapse occurred in only 1 of 23 (4%) IIC patients treated with chemotherapy. A pooled analysis of earlier studies reported a 65% relapse-free survival (RFS) for men receiving radiation therapy for bulky stage II seminoma. Unfortunately, only sparse contemporary data are available on the use of radiation therapy to treat bulky stage II seminomas, and there are no randomized trials comparing radiation therapy with chemotherapy in this population. Combination chemotherapy with cisplatin is effective therapy in patients with bulky stage II seminomas and has become the most widely accepted treatment option.[6,7]
Residual radiologic abnormalities are common at the completion of chemotherapy. Many abnormalities gradually regress over a period of months. Some clinicians advocate empiric attempts to resect residual masses 3 cm or larger, while others advocate close surveillance, with intervention only if the residual mass increases in size. Postchemotherapy radiation therapy is no longer favored, in part because of a retrospective study of a consecutive series of 174 seminoma patients with postchemotherapy residual disease seen at ten treatment centers that reported that empiric radiation was not associated with any medically significant improvement in progression-free survival after completion of platinum-based combination chemotherapy.[Level of evidence: 3iiDiii]
