Active clinical trials for "Abdominal Neoplasms"

St. Jude Children's Research Hospital is studying ways to make ultrasound images clearer - to be able to see blood vessels, body structures, and tumors better. Ultrasound uses sound waves to create pictures, allowing doctors and other medical professionals to "see" inside the body. Researchers are studying a contrast agent (like a dye) called Optison™. St. Jude Children's Research Hospital researchers want to learn the best and safest dose of this ultrasound "dye."

This study aims to compare the effects of local wound infiltration with ketamine versus dexmedetomidine when added to bupivacaine on stress response and postoperative pain in lower abdominal cancer surgery.

This a clinical trial that evaluates the efficacy and safety of three different doses of morphine, namely 1.5 mg, 3 mg and 4.5 mg, via the epidural route regarding reducing pain in elderly patients after a cancer surgery in the lower abdomen

the investigators aim is to investigate the effect of continuous preperitoneal bupivacaine wound infiltration versus epidural analgesia on the inflammatory cytokines response following radical cytectomy

Irreversible electroporation (IRE) is a novel non-thermal ablation modality with promise for revolutionizing the treatment for local solid tumors. With the growing demand for alternative and less invasive treatments for localized tumors, the investigators have seen the development and investigation of several tissue ablation modalities, including radiofrequency ablation (RFA), microwave ablation, and cryoablation. Although these modalities have been efficacious, they have some disadvantages owing to their reliance on thermal energy for creating cell death.

This is a clinical study on patients to compare the effects of CPAP on lung volume diaphragm motion, heart position and tumor motion compared to free breathing. Only patients with significant tumor motion of greater than 1 cm amplitude or unfavorable chest wall geometry (heart close to chest wall) identified on standard imaging and simulation will be candidates for the study. Patients will be re- simulated and planned for radiation treatments with CPAP. The radiation plans generated with and without CPAP will be compared to evaluate the impact of CPAP on tumor motion and dose delivered to adjacent critical structures such as the heart and lung.

This research will confirm that Pcv-aCO2 is suitable for the guidance of early fluid therapy and the evaluation of the prognosis of patients with abnormal hemodynamics after abdominal tumor surgery, and is expected to be a new monitoring index to improve the therapeutic effect of these patients.

Background: Preoperative exercise training programs of long duration, that delay surgical resection of tumors, may not be feasible in the treatment of malignant disease. In people with lung cancer, improvements in postoperative outcomes have been demonstrated with short duration (i.e. up to seven days) preoperative exercise training programs. However, the feasibility of short duration preoperative exercise training programs in people with abdominal cancer has not been investigated. Objective: In people undergoing surgical resection for abdominal cancer, to investigate the effects of a seven-day preoperative exercise training program on preoperative exercise capacity and peripheral muscle strength as well as adherence rates, adverse events and subjective perception of satisfaction and discomfort of participants to the preoperative treatment. Design: A feasibility study. Setting: Participants will be recruited from the surgical ward of a public hospital in São Paulo, Brazil. Participants: 22 inpatients over 18 years old, awaiting surgical resection for colorectal, esophageal, gastric, hepatic or pancreatic cancer. Intervention: The participants will undergo a seven-day, inpatient preoperative exercise training program that includes aerobic and resistance exercises. Measurements: preoperative exercise capacity, peripheral muscle strength, adherence rates (consent rates, recruitment rates, completion rates and adherence), adverse events, the reasons for ineligibility and the reasons for declining participation and the subjective perception of satisfaction and discomfort of the participants to the preoperative treatment.

High-intensity focused ultrasound (HIFU), a recently developed tumor ablation equipment, can be a non-invasive treatment for solid tumors. The principle of HIFU is physically focus the ultrasound point on the biological tissue to form high-intensity ultrasound focus, and kill tumor cells by the thermal effects, mechanical effects and acupuncture effects of the high-intensity ultrasound.

To determine the yield of tissue biopsy specimen and the diagnostic accuracy of tissue acquisition using a newly developed 22 gauge needle in patients with solid lesions throughout the GI tract.
