Refer to the Treatment Option Overview section of this summary for a more detailed discussion of the roles of surgery, radiation therapy, and chemotherapy.
In the setting of lung metastasis, resection of metastatic tumors may be associated with long-term disease-free survival in patients selected for optimal underlying disease biology (i.e., patients with a limited number of metastases and slow tumor growth).[1,2,3] It is not clear to what degree the favorable outcomes are attributable to the efficacy of surgery or to careful selection of patients based upon factors that are associated with less-virulent disease.[1,2,3] The value of resection of hepatic metastases is unclear.
Cannabis, also known as marijuana, is a plant grown in many parts of the world (see Question 1).
The use of Cannabis for medicinal purposes dates back to ancient times (see Question 3).
By federal law, possessing Cannabis is illegal in the United States (see Question 1).
In the United States, Cannabis is a controlled substance that requires special licensing for its use (see Question 1 and Question 3).
Cannabinoids are active chemicals in Cannabis that cause drug -like effects...
As noted in the Treatment Option Overview section above, doxorubicin is the standard systemic therapy in the management of metastatic sarcomas.[4,5] Other drugs that are felt to have clinical activity as single agents are ifosfamide, epirubicin, gemcitabine, and paclitaxel.[6,7,8,9] Their clinical activity relative to single-agent doxorubicin is not clear, and they are not known to have superior activity. There is controversy about whether adding drugs to doxorubicin offers clinical benefit beyond what is achieved by doxorubicin as a single agent. For older patients to avoid severe toxicity, sequential use of single agents may be the preferred strategy for palliation.
Standard treatment options
Single-agent chemotherapy, with subsequent single agents for disease regrowth.[4,5,6,8,9,10] Doxorubicin is generally the first-line agent. Ifosfamide also has substantial single-agent activity.
Doxorubicin-based combination chemotherapy. A variety of regimens have been used, but none has been proven to increase overall survival compared to doxorubicin alone.[4,5] There is some evidence that the addition of ifosfamide increases response rates (but not survival). Toxicity is increased with the addition of drugs to doxorubicin. No quality-of-life studies have been reported in comparisons of single-agent therapy versus combination therapy.
Resection of pulmonary lesions may be performed if the primary tumor is under control.[1,2,3]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage IV adult soft tissue sarcoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
