Brief summary: In patients with unresectable soft tissue sarcoma, what is the response rate if treated with Alimta and gemcitabine?

Detailed description: Soft tissue sarcomas represent 0.7% of all malignancies diagnosed in the United States. The peak incidence occurs in children and young adults with a second peak occurring in middle age, resulting in significant morbidity and mortality in young, productive individuals. Although limb preserving surgery and radiation therapy have improved the primary treatment of these tumors, the therapy of advanced, metastatic tumors is unsatisfactory. The purpose of this phase II study is to evaluate the efficacy of treatment with Alimta and gemcitabine given on day 1 of a 14 day cycle to patients with unresectable or metastatic soft tissue sarcomas. Gemcitabine is an established salvage therapy for soft tissue sarcomas in combination with docetaxel. Alimta is a multitargeted antifolate drug which inhibits several folate dependent enzymes required for cell proliferation. Alimta has shown efficacy in several solid tumor types both as a single agent and in combination with other agents. The combination of Alimta and gemcitabine is synergistic and is likely to have efficacy against soft tissue sarcomas. The primary objective of this study is to determine the response rate among patients with unresectable soft tissue sarcoma treated with this combination. Secondary endpoints will evaluate the median survival of this patient population, as well as time to objective tumor response, time to treatment failure and overall survival. The toxicities of this regimen in this population will also be analyzed. Given the desperate need for new agents to treat these patients, a phase II trial of this combination therapy should be pursued.

Eligibility criteria: Inclusion Criteria:

* Histologically proven soft tissue sarcoma (except the following histologies: gastrointestinal stromal tumors (GIST), Kaposi's Sarcoma, mesotheliomas).
* Age ≥ 18 years
* Recurrent or progressive disease defined as an increase in size of any existing tumor mass, or the development of new tumor mass or masses, which is not amenable to definitive surgical therapy.
* Patients may have had another cancer but there must be convincing clinical evidence that the sarcoma is the disease requiring therapeutic intervention. (i.e. Several sarcoma patients have had had a prior cancer \[Hodgkin's disease or breast cancer\] treated years previously and then developed a clinically active sarcoma.)
* Patients may have received no prior chemotherapy, or may have failed 0-2 prior cytotoxic regimens.
* Measurable disease defined as lesions that can be measured in at least one dimension by physical examination or by means of medical imaging techniques. Ascites and pleural effusions will not be considered measurable disease.
* Karnofsky performance status of greater than or equal to 60%.
* At least 3 weeks since prior chemotherapy or at least 6 weeks since prior radiation therapy.

Exclusion Criteria:

* Soft tissue sarcomas with the following histologies: gastrointestinal stromal tumors (GIST), Kaposi's sarcoma, mesotheliomas.
* Active or uncontrolled infection
* Prior treatment with gemcitabine or Alimta
* Pregnant or lactating women
* Uncontrolled central nervous system metastases
* Inability to stop treatment with NSAIDs
