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
The evidence on the value of aspirin, statins, metformin, beta-blocking ACE inhibitors agents as chemopreventive agents in patients with pancreatic ductal adenocarcinoma is limited. The aim of this study is to assess whether regular use of aspirin, statins, metformin, angiotensin converting enzyme (ACE)-inhibitors and beta-blocking agents use, before diagnosis, after surgery and in neo-adjuvant treatment setting, can increase rate of disease-free survival (DFS) and overall survival (OS) in participants with pancreatic ductal adenocarcinoma. The secondary aim is to evaluate if there is any difference in terms of "chemoprevention" between aspirin, statins, metformin and beta-blocking as chemopreventive agents, and if their prolonged daily use can positively influence the chemopreventive action. 400 patients with the following inclusion criteria will be enrolled in 3 years: 1. cytological or histological diagnosis of pancreatic ductal adenocarcinoma in any portion of the gland, with or without metastases in other sites 2. patient age between 18 and 90 years 3. any medicine or drug in the daily patient therapy 4. Patients undergone to primary chemoradiotherapy or surgical resection, followed by adjuvant therapy or preceded by neoadjuvant chemoradiotherapy, are included in the study Anamnestic, clinical and pathological data, included data on the aspirin, statins, metformin, angiotensin converting enzyme (ACE)-inhibitors and beta-blocking agents assumption will be collected during the first visit with the surgeon. A database managed by a dedicated data manager will be created to collect and analyse data. Patients will be followed for at least 24 months The study will last overall 5 years.
