Resection

This phase I trial studies the safety of giving multiple intracerebral doses of NSC-CRAd-S-pk7 to treat patients with glioblastoma at first recurrence. NSC-CRAd-S-pk7 consists of neural stem cells that can target glioblastoma cells and carry a virus, which can kill cancer cells. Giving multiple doses of NSC-CRAd-S-pk7 may kill more tumor cells.

This phase I trial tests the safety, side effects, and best dose of triapine in combination with temozolomide in treating patients with glioblastoma that has come back after a period of improvement (recurrent). Triapine inhibits an enzyme responsible for producing molecules required for the production of deoxyribonucleic acid (DNA), which may inhibit tumor cell growth. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Giving triapine in combination with temozolomide may be safe, tolerable, and/or effective in treating patients with recurrent glioblastoma.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related incidence and mortality in China and represents a major public health challenge. Surgical resection is the most commonly used curative treatment for HCC and can provide favorable long-term outcomes. However, resection is associated with substantial perioperative morbidity, and its applicability is limited in certain patient populations, including those with recurrent disease, those who have undergone conversion therapy, and those with significant coexisting medical conditions. Advances in radiotherapy technology and the development of highly precise delivery techniques have led to the increasing use of stereotactic body radiotherapy (SBRT) in the management of HCC, particularly in patients with small tumors. Randomized controlled trials conducted by our group have shown that, in patients with recurrent small HCC, SBRT provides superior local tumor control compared with radiofrequency ablation. These findings suggest that SBRT may represent a potentially curative treatment option for selected patients with small HCC. On the basis of this evidence, the present study is designed to compare the efficacy and safety of surgical resection and SBRT in patients with small HCC. Patients with a solitary tumor measuring 5 cm or less in maximum diameter will be randomly assigned to undergo either surgical resection or SBRT. The primary end point of the study is overall survival. This trial aims to define the relative benefits and risks of these two treatment strategies and to provide high-quality evidence to inform clinical decision making and future guideline recommendations.

This phase I trial studies the side effects and best dose of EGFR/IL13Rα2 pool-chimeric antigen receptor (CAR) T cells when given through a thin, flexible tube into the brain (locoregional administration) in treating patients with high-grade gliomas that have come back after a period of improvement (recurrent) or that are growing, spreading, or getting worse (progressive). EGFR/IL13Rα2 pool-CAR T cells are a type of CAR T cell therapy. CAR T cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack tumor cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's tumor cells is added to the T cells in the laboratory. The special receptor is called a CAR. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers.

This phase I trial is to find out the best dose, possible benefits and/or side effects of engineered natural killer (NK) cells containing deleted TGF-betaR2 and NR3C1 (cord blood \[CB\]-NK-TGF-betaR2-/NR3C1-) in treating patients with glioblastoma that has come back (recurrent). CB-NK-TGF-betaR2-/NR3C1- cells are genetically changed immune cells that may help to control the disease.

This phase I trial investigates the effects of influenza vaccine in treating patients with stage I-IV melanoma. While intramuscular administration of influenza vaccine provides immunization against the influenza virus, giving influenza vaccine directly into the tumor (intralesional) may decrease the size of the injected melanoma tumor, or the extent of the melanoma within the body.

This trial will evaluate the efficacy and safety of various therapies in participants with Stage IB, IIA, IIB, IIIA, or selected IIIB resectable and untreated NSCLC tumors that meet protocol-specified biomarker criteria.

This phase I trial tests the safety, side effects and best dose of TGFβR2KO/IL13Rα2 chimeric antigen receptor (CAR) T-cells given within the skull (intracranial) in treating patients with glioblastoma or IDH-mutant grade 3 or 4 astrocytoma that has come back after a period of improvement (recurrent) or that is growing, spreading, or getting worse (progressive). CAR T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack tumor cells. T cells are taken from a patient's blood. When the cells are taken from the patient's own blood, it is known as autologous. Then the gene for special receptors that bind to a certain proteins on the patient's tumor cells are added to the T cells in the laboratory. The special receptors are called CAR. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain tumors. Giving TGFβR2KO/IL13Rα2 CAR T cells may be safe, tolerable, and/or effective in treating patients with recurrent or progressive glioblastoma or grade 3 or 4 IDH-mutant astrocytoma.

This phase III trial compares total ablative therapy and usual systemic therapy to usual systemic therapy alone in treating patients with colorectal cancer that has spread to up to 4 body sites (limited metastatic). The usual approach for patients who are not participating in a study is treatment with intravenous (IV) (through a vein) and/or oral medications (systemic therapy) to help stop the cancer sites from getting larger and the spread of the cancer to additional body sites. Ablative means that the intention of the local treatment is to eliminate the cancer at that metastatic site. The ablative local therapy will consist of very focused, intensive radiotherapy called stereotactic ablative radiotherapy (SABR) with or without surgical resection and/or microwave ablation, which is a procedure where a needle is temporarily inserted in the tumor and heat is used to destroy the cancer cells. SABR, surgical resection, and microwave ablation have been tested for safety, but it is not scientifically proven that the addition of these treatments are beneficial for your stage of cancer. The addition of ablative local therapy to all known metastatic sites to the usual approach of systemic therapy could shrink or remove the tumor(s) or prevent the tumor(s) from returning.

This phase I trial studies the performance, including ultrasound visibility, of an optimized ultrasound twinkling marker in imaging lymph nodes in patients with clinically node-positive breast cancer. In patients with biopsy-proven breast cancer, biopsy markers are used to identify the sites of cancer involvement in both the breasts and lymph nodes. These biopsy markers are critical for guiding surgical management many months after the marker is placed. For breast radiologists and breast surgeons, there is a need for simple, consistent visibility of biopsy markers by ultrasound, particularly several months after marker placement. Ultrasound is the imaging method of choice, particularly for lymph nodes in the armpit (axilla). Ultrasound is non-ionizing and is more comfortable for patients compared to mammography. However, ultrasound visibility of these markers is challenging and inconsistent, with ultrasound failing to detect the marker approximately 25% of the time. The Mayo-designed investigational biopsy marker takes advantage of an ultrasound phenomenon called twinkling artifact. The Mayo-designed optimized ultrasound twinkling marker may work better than standard biopsy clip marker in imaging lymph nodes in patients with clinically node-positive breast cancer.
