A Multicenter, Prospective Study on the Prognostic Value of PSMA PET in Patients With Newly Diagnosed, Treatment-naïve Prostate Cancer

Xijing Hospital · The First Hospital of Lanzhou University, Lanzhou, Gansu

Brief Summary: Under the support of the PROMISE scoring criteria, PSMA PET has demonstrated significant prognostic value. However, previous studies on PSMA PET included patients with various stages of prostate cancer, and the mixture of different disease stages may compromise the accuracy of prognostic tools. This study aims to specifically investigate the prognostic value of initial staging PSMA PET for progression-free survival in patients with newly diagnosed, treatment-naïve prostate cancer, and to develop corresponding prognostic tools. Need: The prognostic value of initial staging with PSMA PET is needed for treatment management and study design. Primary Outcome: To assess the prognostic value of initial staging by PSMA PET: generate a prognostic tool (PSMA-VISION score) based on initial staging of PSMA PET to predict progression-free survival. Secondary Outcomes: To compare PSMA-VISION score with the other prognostic tools (such as NCCN, STARCAP, PPP nomogram, PPP2 nomogram, etc.) and to evaluate the prognostic value of initial staging by PSMA PET to predict overall survival (OS). The correlation with clinicopathological variables and prediction of early progression (Exploratory) was also investigated. Inclusion: 1. Patients with pathologically confirmed prostate cancer by prostate biopsy. 2. Undergone PSMA PET examination as initial staging before any treatment. 3. Have at least 2 years of follow-up data for progression-free survival and overall survival. Exclusion Criteria: 1. Patients undergone any prior prostate cancer treatment before undergoing PSMA PET imaging. 2. Patients with metastasized or disseminated malignancy other than prostate cancer 3.

A Mobile Application to Improve the Quality of Colonoscopy in Colorectal Cancer Screening Program (PrepColon APP)

Hospital del Rio Hortega · Hospital Universitario Rio Hortega, Valladolid, Valladolid

Colonoscopy is the gold standard for the diagnosis and resection of preneoplastic lesions, allowing the prevention of colon cancer. A colonoscopy is more efficient with proper preparation of the colon, as it allows for a higher rate of adenoma detection and cecal intubation. In routine practice, up to 30% of colonoscopies are poorly prepared and 11% of patients do not show up for their appointment. Adenomas not visualized in the initial colonoscopy due to poor preparation reached 68% and the rate of undetected cancers was 66.7%. A proper colon cleanse is conditioned by different factors; among them, failure to comply with the diet and take laxatives poses 5 times the risk of having a deficient colon preparation. The purpose of our study is the design and implementation of an app that facilitates the preparation of colonoscopy and evaluates its impact on compliance with diet and laxative intake.

Eligibility: 50 Years to 74 Years · All · * -Subjects between 50-69 years old from the CRC screening program with FIT (\>100ng/ml). * Informed consent granted in writing

Evaluation of Geriatric Assessment and Management for Older Adults With Non-small Cell Lung Cancer Receiving Chemotherapy Radiation Therapy

City of Hope Medical Center · City of Hope Medical Center, Duarte, California

This clinical trial tests how well a geriatric assessment (GA) with GA-directed treatment recommendations, compared to GA with usual care, works in identifying risk factors, reducing chemotherapy radiation toxicity and functional decline, and improving the overall quality of life in older patients with non-small cell lung cancer (NSCLC). Older patients with lung cancer undergoing chemotherapy are at an increased risk of adverse outcomes including treatment toxicity and functional and physical consequences. This makes it very challenging for the physicians to balance the benefits against the risk of chemotherapy in older cancer patients. A geriatric assessment may be useful in identifying risk factors for chemotherapy radiation toxicity. Communicating these geriatric assessment findings and assessment-based recommendations to a patient's treating physicians may help them make more informed decisions about treatment options for patients. Making treatment decisions using GA-based recommendations may reduce adverse events and improve outcomes in patients receiving treatment for NSCLC.

Eligibility: 60 Years to · All · * ONCOLOGY PHYSICIANS INCLUSION: * Oncology physicians must work at the participating site with no plans to leave that site or retire at the time of enrollment into the study * PATIENTS INCLUSION: * Any patient with unresectable non-small cell lung cancer diagnosis who is 60 years of age or older and must be treated at the participating site * Clinical staging without pathological confirmation of nodal disease is allowed * Plan to start a new cancer treatment regimen within 4-6 weeks from time of baseline study visit. The treatment regimen is up to the discretion of the treating oncology physician. The regimen must include a chemotherapy drug or other agents that have similar prevalence of toxicity. This can be either concurrent or sequential with radiation therapy * Chemotherapy will be defined as cytotoxic drugs; in addition, agents (e.g., monoclonal antibodies and targeted agents) will be allowed. Given the rapidly changing landscape of new drugs for cancer, the study team led by the principal investigator (PI) will update the list accordingly after reviewing the toxicity profile of new therapies * Patients who are receiving approved cancer treatment in combination or sequentially with radiation including hypo fractionated radiation (45-60Gy in 15-20 fractions) are eligible * Those patients with oligometastatic disease having only one site and one lesion outside of the radiation field will be eligible. Examples include a solitary brain metastasis (met), contralateral lung nodule or an adrenal metastatic site * A patient may also be enrolled on a treatment trial and participate in this study, if all other inclusion and exclusion criteria are met * Able to provide informed consent, or if the oncology physician determines the patient to not have decision-making capacity, a patient-designated health care proxy (or authorized representative per institutional policies) must sign consent by the baseline visit * Participant or healthcare proxy has adequate understanding of the English language (preferred) because not all GA measures have been validated in other languages. Study team should be contacted for any participants with other preferred languages including Spanish and Mandarin. Inclusion of these participants will depend upon the availability of the translators and their ability to accurately translate the measures as approved by the local Institutional Review Board (IRB)
