Filter by:For now, neoadjuvant chemoradiotherapy is routinely performed for T3N1-2M0 rectal cancer. However, there are lots of complications following neoadjuvant chemoradiotherapy, such as Wound-related complications, anastomotic leakage, anastomotic stenosis, sexual dysfunction, testicular or ovary failure. Patients undergoing resection for rectal cancer had low rates of local recurrence and long disease-free survival regardless of whether an APR, CAA or low AR was performed. The main purpose of preoperative radiotherapy is to lower the local recurrence. For the T3N1-2M0 rectal cancer with negative circumferential resection margin based on MRI assessment, we suppose might not necessary to receive neoadjuvant chemoradiotherapy, for operation can achieve the negative circumferential resection margin.
Breast cancer is the most prevalent cancer affecting women. To treat locally advanced breast cancers, neoadjuvant chemotherapy (NACT) is often carried out before surgery to reduce the tumour size to allow breast conservation surgery. However, treatment response for individual patients varies, where the tumour may not respond to treatment and the quality of patient care is compromised if the NACT treatment plan is not optimised. Therefore, the assessment of NACT efficacy is beneficial for the early identification of these patients and appropriate management of treatment. Breast tumours have unique features compared to healthy tissue, including abnormal tissue structure and biochemical composition. With NACT there are specific changes to such tumour features indicating tumour treatment response. The purpose of this study is to establish how the changes to breast tumour features following NACT treatment are seen in non-invasive imaging. This study will look at scans of breast tumours using magnetic resonance imaging (MRI). Changes to tissue structure will be measured by advanced diffusion MRI techniques and changes to tumour related biochemical substances will be measured by advanced magnetic resonance spectroscopy techniques. The investigators aim to assess if these techniques can provide information on the tumour treatment response following subsequent rounds of NACT treatment. In this longitudinal study, 25 patients undergoing NACT will be recruited for four repeated MRI investigations over the course of NACT treatment. Magnetic resonance (MR) measurements of tissue microstructure and biochemical composition will be compared against histological measurements and radiological assessments of treatment response. The study will recruit patients undergoing treatment at the NHS Grampian. This research is funded by Friends of ANCHOR, Tenovus Scotland Grampian and the NHS Grampian Endowment Research Fund.
The main objective of the study is to show that the addition of ultrasonography to the dual tracer scintigraphy MIBI-Tc99m/Iodine-123 will increase (at least +5%) the negative predictive value compared to the dual tracer scintigraphy alone in detection of malignancy in thyroid nodules ≥15 mm classified as Bethesda III-IV on cytology.
This study proposes to establish a CT radiomics-based prediction model for identifying metastasis of each station lymph nodes in gastric cancer.
Background Information With the advance in cancer biology, we realize that malignant neoplasm is related with different biological patterns in metabolome and microbiota. Because of the progress in optical spectrometry, it has become possible to evaluate whole visible and innon-visiable absorptive spectrum in human specimens, which may enable detection of minor changes in compound related with altered metabolome and microbiota. We hope to utilize hyperspectral imagingthis spectrum technology to reveal the possible clues of neoplasm for early stage detection Material and Methods This research intended to enroll one hundred patients into the study. This includes patients with positive stool or urine analysis admitted for workup of colorectal cancer. We will scan the stool and urine with hyperspectral imaging sensoroptical spectrometer, which utilize multichannel charge-coupled device and InGaAs array to analyze the full spectrum of light patterns. The image pattern will be stored and used to linked final diagnosis. Absorption, scattering, and reflection spectra are expected for analysis. Follow up analysis after cancer staging will be used for lowering background noise in all spectra. Expected Results We expect that there will be specific spectral pattern in stool of colorectal cancer patients, which may be related with cancer staging and different from those in patients without malignancy. Difference in spectra will lead to discovery of new biomarker for colorectal cancer and related diseases. The optic spectra pattern of stool and urine may assist early diagnosis and staging of different malignancies
AIM1a: AYAs with cancer experience many challenges that impact their health-related quality of life (HRQOL) but few measures adequately capture AYAs' HRQOL in valid and reliable ways. The main goal of the study is to expand the use of the Patient-Reported Outcome Measurement Information System (PROMIS) to provide valid and reliable assessment of important HRQOL concerns for AYAs. The study team will do this by validating existing PROMIS measures and developing and validating new measures of financial distress, fertility/parenthood concerns, and body image concerns for AYAs with cancer. AIM1b: Investigators have developed conceptual frameworks and created item pools for body image, fertility, and financial burden domains and are ready to proceed with the next aim of our measure development work, cognitive interview testing.
Assessment of the efficacy and safety of Regorafenib and Avelumab in patients with advanced or metastatic solid tumors (ten cohorts), once the Recommanded Phase II Dose (RP2D) has been determined (phase I trial). Assessement of the efficacy and safety of a low-dose of regorafenib (80mg/day) with avelumab in patients with advanced or metastatic colorectal tumors.
This phase Ib/II trial studies the side effects and best dose of venetoclax and how well it works when given together with ivosidenib with or without azacitidine, in treating patients with IDH1-mutated hematologic malignancies. Venetoclax and ivosidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ivosidenib and venetoclax with azacitidine may work better in treating patients with hematologic malignancies compared to ivosidenib and venetoclax alone.
The purpose of this phase II trial is to determine the feasibility and efficacy of nimotuzumab combined with concurrent chemoradiotherapy for initially inoperable locally advanced cervical squamous cell carcinoma.
The purpose of this study is to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of humanized anti-PD-1 monoclonal antibody, HLX10, in patients with advanced or metastatic tumors refractory to standard therapy. This study will also evaluate the pharmacokinetics, pharmacodynamics, immunogenicity and anti-tumor effect of HLX10 and explore the potential prognostic and predictive biomarkers.
