Active clinical trials for "Precancerous Conditions"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combining topotecan, fluorouracil, and leucovorin in treating patients who have advanced cancer.

RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy and radiation therapy used to kill tumor cells. PURPOSE: Phase I trial to study the effectiveness of treated donor stem cell transplantation in treating patients who have hematologic cancer.

RATIONALE: Radiation therapy uses high-energy x-rays to damage cancer cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation in treating patients who have hematologic cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of combining docetaxel, ifosfamide, and carboplatin followed by peripheral stem cell transplantation in treating patients with refractory cancer.

This is a multicenter minimal risk or burden prospective 3-cohort follow-up and monitoring study that aims to collect clinical, socio-psychological, medico-economics data and biospecimens for patients with oral potentially malignant lesions (OPML) or resectable head and neck squamous cell carcinoma (HNSCC) : Cohort A: OPML patients. Cohort B (specific design): smokers (adults who have smoked at least 100 cigarettes in their lifetime) motivated to quit - either current smokers (who currently smokes cigarettes every day (daily) or some days (nondaily)) or former smokers (adults who have smoked at least 100 cigarettes in their lifetime, but say they currently do not smoke) who stops smoking within 3 months prior to the diagnosis - with a resectable HNSCC requiring postoperative radiotherapy or chemoradiation. Cohort C: Patients with resectable HNSCC non-eligible to cohort B. The primary objective of this study is the identification of biomarkers (predictive of malignant transformation or second primary tumor) and new strategies for prevention and therapy, mainly through extensive genomic, epigenomic and immune characterization of OPML and HNSCC.

RATIONALE: Photodynamic therapy uses light and drugs that make cancer cells more sensitive to light to kill tumor cells. Photodynamic therapy using aminolevulinic acid may be effective in treating patients with skin cancer. PURPOSE: This randomized phase II trial is studying how well photodynamic therapy that includes aminolevulinic acid works in treating patients with skin cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of decitabine in treating patients with stage III or stage IV melanoma or other advanced cancer that has not responded to previous therapy.

RATIONALE: Interleukin-2 may stimulate a person's white blood cells to kill metastatic cancer cells. Interferon alfa may interfere with the growth of the cancer cells. Combining interleukin-2 and interferon alfa may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of interleukin-2 plus interferon alfa in treating adults with metastatic cancer.

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of vitamin D may keep colorectal cancer from forming in patients with colon polyps. PURPOSE: This randomized phase I trial is studying a vitamin D supplement to see how well it works compared with a placebo in preventing colorectal cancer in African Americans with colon polyps.

RATIONALE: Pemetrexed disodium may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Studying samples of cerebrospinal fluid and blood from patients with cancer in the laboratory may help doctors learn how pemetrexed disodium works in the body and identify biomarkers related to cancer. PURPOSE: This clinical trial is studying the side effects and how well pemetrexed disodium works in treating patients with leptomeningeal metastases.
