Filter by:The data will be obtained from 10 tertiary centers located in Poland (Cracow - coordinating center, Warsaw - 3 centers, Sosnowiec, Szczecin, Bydgoszcz, Lublin, Gdansk, Poznan) and 5 foreign centers. The analyses will include patients with rectal cancer operated on between 2013-2019. A database in MS Excel is prepared that consists of following data: - Type of neoadjuvant treatment (if any) - Time-interval between the end of neoadjuvant treatment and surgery - Type of surgery - Staging of rectal cancer i.e. (y)pTNM - Number of retrieved lymph nodes - Number of lymph nodes with metastases - R classification (R0, R1, R2) - Preoperative medications (metformin, statins, NSAIDs, anticoagulants) - Recurrence date and type (local, systemic, both diagnosed at the same time) - Date of death or date of last follow-up visit The aims of the study are following: 1. Establishing whether neoadjuvant treatment (PSCR or chemoradiotherapy) influences number of retrieved lymph nodes in rectal cancer 2. Establishing whether time-interval between the end of PSCR and surgery influences lymph node yield 3. Establishing the prognostic value of lymph node ratio - validation of the previously calculated cutoff point at the level of 0.41 4. Determining independent prognostic factors in rectal cancer - in particular related to medications taken before the operation, metformin and anti diabetic drugs in the first place
Patients with locally advanced gastric adenocarcinoma (cT2-4a N-/+ M0) were selected as study subjects to investigate the safety, efficacy, and feasibility of ICG near-infrared imaging tracing in guiding laparoscopic D2 lymph node dissection for gastric cancer after neoadjuvant chemotherapy by comparing injection ICG group and non-injection ICG group
The study is a prospective, single arm phase I/II study. The primary aim of this study is to evaluate the feasibility of 111In-PSMA I&T radio guided surgery in patients diagnosed with prostate cancer who are highly suspected of having one or more pelvic lymph node metastases based on pre-operative imaging. Patients with prostate cancer who have a high risk of lymph node metastases based on PSMA PET/CT and scheduled for robot-assisted PLND (with or without prostatectomy) will be recruited. Eligible patients will receive an additional ferumoxtran-10 enhanced MRI to complement pre-operative imaging. Twenty-four hours before surgery, patients will receive the radiolabelled PSMA tracer. Pelvic Lymph node dissections are carried out according to standard of care procedures. During surgery, the surgeon will be provided with a gamma-probe to detect PSMA expressing lymph nodes in vivo. Dissected samples will be systematically assessed on tracer accumulation using the gamma-probe ex vivo. After surgery, the samples will be scanned in the small animal SPECT/CT and 7T-MRI. After scanning, samples will be presented to pathologists for pathological analysis according to standard of care including staining for PSMA expression. At 3 months after surgery, patients will undergo a PSMA-PET/CT. Up until one year after surgery patients will be followed according to standard of care-guidelines by 3-monthly serum-PSA measurements.
The infrapyloric (No.206) and greater curvature (No.204) lymph node metastasis in adenocarcinoma located at hepatic flexure and right half of transverse colon has not been well discribed and analysed. The aim of this study is to assess the rate of this lymph node metastasis and to reveal its prognostic value for colon cancer located at hepatic flexure and right half of transverse colon. Meanwhile, we can evaluate the safety and feasibility of this extented lymphadenectomy in right hemi-colectomy.
This study will evaluate the clinical and pathological response to vemurafenib and cobimetinib in the neoadjuvant treatment of patients with histologically confirmed, BRAF V600 mutation-positive Stage IIIB and C melanoma. 20 patients will be treated with vemurafenib and cobimetinib for 2 months. Then they will be assessed for surgery. Patients will undergo surgery and subsequently resume taking vemurafenib and cobimetinib after recovery from surgery. Patients will undergo radiation therapy if appropriate then continue vemurafenib and cobimetinib. The maximum treatment period is 12 months. After 12 months of treatment, patients will be followed for disease recurrence and survival during for a total of 5 years.
This clinical trial studies positron emission tomography (PET)/computed tomography (CT) and lymph node mapping in finding lymph node metastasis in patients with endometrial cancer that is at high risk of spreading. A PET/CT scan is a procedure that combines the pictures from a PET scan and a CT scan, which are taken at the same time from the same machine. The combined scans give more detailed pictures of areas inside the body than either scan gives by itself. Lymph node mapping uses a radioactive dye, called indocyanine green solution, to identify lymph nodes that may contain cancer cells. PET/CT and sentinel lymph node mapping may be better ways than surgery to identify cancer in the lymph nodes.
This randomized phase IIA trial studies how well antiandrogen therapy works with or without axitinib before surgery in treating patients with previously untreated prostate cancer that is known or suspected to have spread to lymph nodes. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as antiandrogen therapy may lessen the amount of androgen made by the body. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known if antiandrogen therapy is more effective with or without axitinib before surgery in treating patients with prostate cancer.
This proposal is targeted at all patients with prostate cancer who are candidates for either curative surgery or curative radiotherapy in whom lymph node staging is indicated. Recently, it has been shown, that in patients with PSA <10 ng/ml and Gleason score < 7 the risk of lymph node metastases is low. Therefore, unnecessary PLND and non-invasive imaging can be avoided safely in this group. PLND is nowadays performed only in patients with intermediate or high risk for nodal metastases. Thus the subgroup of patients targeted in this study consists of patients with prostate cancer with a PSA >10 ng/ml and Gleason score > 6. - If the high sensitivity (90%) and negative predictive value (96%) of MRL can be validated in the 8 participating centres, in patients with a negative MRL invasive PLND may be avoided. - In patients with a positive MRL with enlarged nodes (larger than 8 mm) histological diagnosis may be obtained by imaged guided biopsy, and thus also in these patients avoid PLND. A limitation of image guide biopsy, however, is the 30% false negative rate. [Barentsz, Oyen, Wolf] - In patients with positive small nodes (smaller than 8 mm) the urologist may, focussed by the MRL findings of a positive node outside his “surgical field-of-view”, extend his dissection, and thus improve his accuracy. - Based on the expected higher sensitivity of MRL this technique will completely replace CT-scanning.
