Soft Tissue Sarcoma

Grade II sarcoma, Grade III sarcoma
Brief summary
The purpose of this Phase 1 research study is to obtain data or information on the safety and effectiveness of the combination of gemcitabine, docetaxel with radiation.
Detailed description
Primary Objective: • To determine the maximum tolerated doses Gemcitabine and Taxotere when given weekly with concurrent radiation in the neoadjuvant setting for patients with soft tissue sarcoma of the extremities. Secondary Objective: • To evaluate immunological changes induced by gemcitabine and docetaxel with radiation in patient with high risk-soft tissue sarcomas in blood. This would include T cell subsets, NK, and dendritic cells and tumor macrophages all of which make up the tumor microenvironment. Long term follow-up will occur every 3-4 months for 24 months in person or video consultation.
Interventions
Gemcitabine will be administered on day 1 of each one-week cycle for 6 cycles concurrently with radiation to the extremity on a 3+3 escalating dose (100 mg/m² to 300 mg/m²)
Docetaxel will be administered on day 1 of each one-week cycle for 6 cycles concurrently with radiation to the extremity (10 mg/m² to 25 mg/m²).
Radiation is to be done with standard preop dose of 50 Gy but at lower doses per fraction. Thus 50.4 Gy in 28 FX. Radiation will be given for 5 days (Monday - Friday) every week for approx. 6 weeks.
Upon completing neoadjuvant chemotherapy plus radiation therapy, surgical resection will occur.
Before treatment, blood (about 2 tubes of 10 mls each) to better understand some aspects of participants' immune system before chemotherapy.

Eligibility
Inclusion criteria
* Patients must have a histologically or cytologically confirmed Grade II or III soft tissue sarcoma that is considered to be resectable and are candidates for pre-op radiation. * Age greater than or equal to 18 years. No children will be enrolled on this protocol. * Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 2. * Women of child-bearing potential and men must agree to use adequate contraception (hormonal or double-barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. * Ability to understand and the willingness to sign a written informed consent document.
Exclusion criteria
* Patients taking concurrent hormonal therapy, biologic or other chemotherapy are excluded except women on hormonal contraceptives. * Patients taking an investigational agent are excluded. * Pregnant and nursing women are excluded. * Patients who require amputation for local control. * Patients who underwent unplanned excision or other previous surgery involving the affected extremity. * Patients with sarcoma subtypes for which established chemotherapeutic regimens exist. * History of radiation to the limb.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Maximum Tolerated Dose Chemotherapy and Radiation | Up to 8 weeks | Maximum tolerated dose of Gemcitabine and Taxotere and radiation will be completed by monitoring toxicities and using the 3+3 dose escalation plan. |
| Number of Toxicity Incidences | 8 weeks post-surgery | Complication/side effects from the chemotherapy combination of gemcitabine and taxotere concurrent with radiation will be assessed by toxicity counts/rates presented descriptively by toxicity, severity, and dose level using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Immunological Changes in Blood | 8 weeks post-surgery | The effects of the treatment on the immune system will be analyzed using paired t-test or the non-parametric counterpart. Correlations between immune cells and immune factor levels will be assessed using Spearman correlation coefficient. All tests will be two-sided with a significance level of 0.05, and no adjustment for multiple comparisons will be made due to the exploratory nature of these studies. |
