RATIONALE: Celecoxib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving celecoxib together with radiation therapy after surgery may kill any tumor cells that remain after surgery.
PURPOSE: This phase I trial is studying the side effects and best dose of celecoxib when given together with radiation therapy in treating patients with stage II or stage III soft tissue sarcoma of the arm, hand, leg, or foot that has been removed by surgery.
- Determine the maximum tolerated dose of adjuvant celecoxib administered with radiotherapy in patients with resected stage II or III soft tissue sarcoma of the extremity.
OUTLINE: This is a dose-escalation study of celecoxib.
Beginning within 10 weeks of the most recent resection, patients undergo standard radiotherapy once daily, 5 days a week, in weeks 1-7. Patients also receive oral celecoxib twice daily in weeks 1-7 in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of celecoxib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity. A maximum of 6 patients are treated at the MTD.
After completion of study treatment, patients are followed periodically.
PROJECTED ACCRUAL: A total of 24 patients will be accrued for this study.
Primary Purpose: Treatment

The goal of this clinical research study is to assess the safety of pembrolizumab (also called MK-3475) after radiation therapy (with or without surgery and/or chemotherapy) in patients wi...
This is a study for patients with resectable, locally advanced esophageal cancer. There is evidence to suggest that celecoxib in combination with cisplatin and irinotecan (CPT-11) may work...
The primary objectives of this study are to evaluate whether the administration of AdV-tk to malignant brain tumors followed by anti-herpetic prodrug in combination with radiation therapy ...
RATIONALE: Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from di...
Primary Objectives: - To determine the feasibility, activity, and toxicity of a novel regimen using a concurrent irinotecan (CPT-11)/cisplatin and celecoxib combination for patien...
Local recurrence is a common failure pattern in adenocarcinoma of the cecum. This study aimed to investigate the potential role of adjuvant radiation therapy on oncologic outcomes of patients with ade...
Following radical prostatectomy (RP), adjuvant radiation therapy (RT) decreases biochemical recurrence and potentially improves metastasis-free and overall survival for patients with high-risk patholo...
The Cancer and Leukemia Group B 9,343 demonstrated that postoperative radiation can be safely omitted in women ≥70 years who underwent breast-conserving therapy for clinical stage I (T1N0M0) estroge...
Studies have shown that a number of women do not receive adjuvant radiation therapy following breast-conserving surgery; the reasons have not been well investigated. We reviewed the charts of 267 pati...

Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
A therapeutic approach, involving chemotherapy, radiation therapy, or surgery, after initial regimens have failed to lead to improvement in a patient's condition. Salvage therapy is most often used for neoplastic diseases.
Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
Radiotherapy given to augment some other form of treatment such as surgery or chemotherapy. Adjuvant radiotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
