- [Cardia cancer: attempt at a therapeutically relevant classification]. (201 citations)
What are the main themes of his work throughout his whole career to date?
J. R. Siewert mostly deals with Surgery, Internal medicine, Abdominal surgery, Esophagus and Cardiothoracic surgery.
J. R. Siewert interconnects Gastrectomy, Carcinoma and Esophagectomy in the investigation of issues within Surgery.
His research in Carcinoma intersects with topics in Stage, Lymphadenectomy, Lymph node and Radiology.
His Internal medicine study combines topics from a wide range of disciplines, such as Gastroenterology and Oncology.
The various areas that J. R. Siewert examines in his Abdominal surgery study include Cardiac surgery and Vascular surgery.
As part of the same scientific family, J. R. Siewert usually focuses on Esophagus, concentrating on Adenocarcinoma and intersecting with Pathology.
He most often published in these fields:
- Surgery (40.73%)
- Internal medicine (27.82%)
- Abdominal surgery (20.56%)
What were the highlights of his more recent work (between 2007-2016)?
- Surgery (40.73%)
- Internal medicine (27.82%)
- Gastroenterology (15.73%)
In recent papers he was focusing on the following fields of study:
His primary areas of investigation include Surgery, Internal medicine, Gastroenterology, Carcinoma and Abdominal surgery.
Surgery is closely attributed to Gastrectomy in his research.
His work deals with themes such as Oncology and Conservative treatment, which intersect with Internal medicine.
The Stomach and Serum bilirubin research J. R. Siewert does as part of his general Gastroenterology study is frequently linked to other disciplines of science, such as Progressive encephalopathy, therefore creating a link between diverse domains of science.
His biological study spans a wide range of topics, including Pancreas, Lymph, Endoscopic ultrasound, Radiology and Stage.
His work focuses on many connections between Abdominal surgery and other disciplines, such as Cardiothoracic surgery, that overlap with his field of interest in Vascular surgery and Gynecology.
Between 2007 and 2016, his most popular works were:
- Histopathological response after preoperative radiochemotherapy in rectal carcinoma is associated with improved overall survival. (51 citations)
- Limited resection and free jejunal graft interposition for squamous cell carcinoma of the cervical oesophagus. (44 citations)
- Was leistet die Endosonographie im präoperativen Staging des Ösophaguskarzinoms (35 citations)
In his most recent research, the most cited papers focused on:
- Internal medicine
- Surgery
- Cancer
Carcinoma, Radiology, Surgery, Internal medicine and Gastroenterology are his primary areas of study.
The study incorporates disciplines such as Stage, Preoperative care, Neoadjuvant therapy and Mean age in addition to Carcinoma.
His studies deal with areas such as Preoperative treatment, Pancreas and Lymph as well as Radiology.
J. R. Siewert has researched Surgery in several fields, including Body weight, Gastric carcinoma and Oesophagojejunal.
In the subject of general Internal medicine, his work in Intensive care unit, Serum bilirubin and Pancreatitis is often linked to Amanita phalloides poisoning, thereby combining diverse domains of study.
His study in Gastroenterology is interdisciplinary in nature, drawing from both Bone marrow suppression, Liver transplantation and Rectal carcinoma.
