Inclusion Criteria:

- Histologically confirmed unresectable metastatic or locally recurrent leiomyosarcoma,
Malignant Fibrous Histiocytoma (MFH, also known as high grade Undifferentiated
Pleomorphic Sarcoma) pleomorphic liposarcoma, rhabdomyosarcoma or angiosarcoma.

therapy will not count provided it was more than one year previously.

Therapy may not start until at least 3 weeks since prior cytotoxic chemotherapy, two
weeks from completion of radiation therapy, and one week for patients on tyrosine
kinase inhibitors or other targeted therapy.

- Age 18 To 75. As it is quite difficult to administer high dose docetaxel with
gemcitabine, to the elderly, in order to protect patient safety, we will restrict
eligibility to patients between the ages of 18 and 75.

- ALT (SGOT) or AST (SGPT) < or = to 5 x ULN.

- Alkaline Phosphatase < or = to 2.5 x ULN or ≤ 5 x ULN in presence of liver
metastases.

- Serum creatinine 2.0 mg/dL

- Ability to understand informed consent and comply with treatment protocol

- Normal cardiac ejection fraction

- Urine protein:creatinine (UPC) ratio < than or = to 1.0 at screening

Exclusion Criteria:

- Uncontrolled intercurrent illness including infection or congestive heart failure
within 6 months.

- Prior therapy with gemcitabine, docetaxel or bevacizumab

- Patients receiving other investigational agents

warfarin or low-molecular weight heparin, and have had no major bleeds within the
past 6 months.

diastolic blood pressure > 100 mmHg lasting > 24 hours on antihypertensive
medications)

- Proteinuria at screening as demonstrated by

- Urine protein:creatinine (UPC) ratio > or = to 1.0 at screening (patients discovered
to have UPC ratio > or = to 1.0 at baseline should undergo a 24 hour urine
collection and must demonstrate ≤ 1g of protein in 24 hours to be eligible).

- Known hypersensitivity to any component of bevacizumab

- Pregnant (positive pregnancy test) or lactating. Use of effective means of
contraception (men and women) in subjects of child-bearing potential
