Filter by:This is a non-randomized Phase II study. Patients determined at initial diagnosis to have a carcinoma of unknown primary site will have their treatment selected with the use of a molecular profiling assay. A molecular profiling assay will be performed on paraffin-embedded tumor tissue from a biopsy specimen. Patients given specific diagnoses (e.g., lung, pancreas, colon, breast, renal cell, prostate and ovarian cancer) will receive treatment regimens of proven activity. If no specific diagnosis is made with the molecular profiling assay, empiric chemotherapy with paclitaxel, carboplatin, bevacizumab and erlotinib will be administered.
This randomized phase III trial studies chemotherapy to see how well it works with or without bevacizumab in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or that has spread to other parts of the body (metastatic). Drugs used in chemotherapy, such as docetaxel, cisplatin, carboplatin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. Bevacizumab may also make tumor cells more sensitive to chemotherapy and stop the growth of head and neck cancer by blocking blood flow to the tumor. It is not yet known whether combination chemotherapy is more effective when given with or without bevacizumab in treating patients with head and neck squamous cell carcinoma.
The purpose of this study is to investigate the efficacy of Cisplatin, Paclitaxel, Gemcitabine +/- Avastin (Bevacizumab) in patients with unknown primary tumors.
RATIONALE: Imaging procedures, such as PET scan and CT scan, may help doctors predict a patient's response to treatment and plan the best treatment. PURPOSE: This clinical trial is studying how well PET scans and CT scans show response to treatment in patients with locally advanced head and neck cancer undergoing chemotherapy and radiation therapy.
We will evaluate the feasibility, toxicity, and effectiveness of combination chemotherapy (paclitaxel/carboplatin)plus combination targeted therapy (bevacizumab/erlotinib)in the first line treatment of patients with carcinoma of unknown primary site. There is limited experience with either bevacizumab or erlotinib in the treatment of cancers of unknown site but given the heterogeneous nature of the tumor, it is likely that inhibition of angiogenesis pathways and/or the EGFR pathway are effective strategies in at least a proportion.
RATIONALE: Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well gemcitabine works in treating patients with metastatic cancer of unknown primary.
Primary objectives: 1. To determine the overall tumor response rate with oxaliplatin in combination with gemcitabine (GEMOX) as first line and second line therapy in unknown primary cancer (UPC). 2. To determine the tolerability (toxicity) of this regimen in this patient population. Secondary objectives: 1. To determine the median overall survival (OS) and time to progression (TTP) for patients treated with this combination. 2. To determine the impact of this combination on quality of life (QOL) in this patient population.
Investigate the final diagnosis and treatment result of metastatic cervical carcinoma of unknown primary
Is PET-CT scan better than PET or CT alone in diagnosing primary tumours in patients with unknown primary tumors? Can information obtained with PET-CT replace other clinical and radiological investigations? Is PET/CT cost-effective?
This study will determine the maximum tolerated dose of the triplet combination of capecitabine that can be administered in combination with weekly paclitaxel and every four weeks with carboplatin.
