ENSmall intestine cancer is rare: the small bowel is the longest part of the digestive tract, yet few digestive tumours start there. Symptoms are vague — abdominal pain, anaemia, hidden bleeding, bouts of obstruction — so the tumour is often found late or by chance.
Small intestine cancer treatment in Germany depends above all on the tumour type: one name covers four different diseases. This page covers the types, surgery, drugs, hospitals, costs and travel. Colon and rectal cancer follow other rules — see colorectal cancer treatment in Germany.
Types of small bowel tumours and how they are found
Four main malignant tumours occur in the small intestine. Adenocarcinoma arises from the bowel lining, most often in the duodenum. A neuroendocrine tumour (NET) grows from hormone-producing cells, usually in the last part of the small bowel; it typically grows slowly and sometimes causes flushing and diarrhoea — carcinoid syndrome, mostly once the liver is involved. A gastrointestinal stromal tumour (GIST) starts in wall cells that control bowel contractions. Lymphoma, a tumour of immune cells, is treated by haematologists.
Gastroscopy and colonoscopy miss most of the small bowel, so doctors use capsule endoscopy: a swallowed camera capsule photographs the bowel from inside. Biopsies are taken by balloon enteroscopy, which moves an endoscope along the bowel with inflatable balloons. CT or MR enterography shows the tumour, lymph nodes and metastases. See digestive system diagnostics.
For a suspected NET, doctors add a chromogranin A blood test and PET-CT with a tracer that binds to somatostatin receptors on tumour cells: the weakly radioactive tracer gathers in the tumour and metastases, making them visible. The tumour board decides on treatment once histology — tissue examined under the microscope — is available.
Surgery for small intestine cancer
For adenocarcinoma, GIST and most NETs, surgery is the basis of treatment. With adenocarcinoma and NET, the surgeon removes the affected segment with the lymph nodes of the mesentery, the tissue fold that carries the bowel’s vessels, and joins the ends. In GIST, lymph nodes are usually left alone because these tumours rarely spread to them; the aim is to remove the tumour intact.
A duodenal tumour may need a larger operation, sometimes including part of the pancreas: the Whipple procedure removes the duodenum, the head of the pancreas, the gallbladder and the end of the bile duct, and reconnects the remaining organs to the bowel. It is done in pancreatic surgery centres. In NET, the mesenteric nodes and sometimes liver metastases are also removed, as planned by the tumour board.
Drug therapy and radiotherapy
Drug therapy depends on the tumour type: adenocarcinoma receives chemotherapy after surgery when the risk of recurrence is high, for example with affected lymph nodes, or in advanced disease. Trials are few, so regimens follow those for colon cancer, usually a fluoropyrimidine with a platinum drug. More on chemotherapy in Germany.
GIST is treated with tablets that block growth signals — tyrosine kinase inhibitors — after surgery when the risk of recurrence is high and in metastatic disease; testing the KIT and PDGFRA genes shows which drug is suitable. For NET, doctors use somatostatin analogues, injections that slow growth and ease hormone symptoms, and peptide receptor radionuclide therapy, given in nuclear medicine departments: a radioactive drug finds tumour cells through the same receptors and irradiates them from inside. See targeted therapy for rare tumours; NET management is set out in the guidance of the European Neuroendocrine Tumor Society (ENETS).
Radiotherapy is rarely used for small bowel cancer: the bowel moves and is very sensitive to radiation. It is used selectively, for example for painful bone metastases.
Where small bowel tumours are treated in Germany
Small bowel tumours are operated on in departments experienced in bowel and pancreatic surgery. At Rechts der Isar Hospital (TUM) in Munich, Prof. Helmut Friess directs the Department of Surgery; his main field is pancreatic surgery, and his department treats small bowel cancer, GIST and neuroendocrine tumours of the bowel. In Frankfurt, Prof. Thilo Welsch heads General, Visceral and Tumour Surgery at Nordwest Hospital, focusing on surgical oncology and robotic surgery.
PD Dr Holger Seidl, one of the directors of gastroenterology and gastrointestinal oncology at the ISAR Klinikum in Munich, holds the DGVS certificate in gastrointestinal oncology; his postdoctoral research focused on small intestine motility. Which nuclear medicine departments offer radionuclide therapy is confirmed per request. With a rare tumour, experience with that tumour type matters more than the city: ENETS advises referral to specialised centres of high expertise.
Costs of treatment
Costs are made up of diagnostics (enteroscopy, CT or MRI, PET-CT for NET), surgery with the hospital stay, and drug therapy; the total depends on tumour type and extent of treatment. See cancer treatment costs in Germany.
With GIST and NET, drugs are taken for months or years, so clarify early which parts — injections, tablets, check-ups — can continue at home. The hospital issues an official estimate (Kostenvoranschlag) after reviewing the documents.
Frequently asked questions
Can small intestine cancer be cured?
Yes, if the tumour can be removed completely before it spreads to distant organs; for early-stage adenocarcinoma, surgery is the only curative option. The outlook depends on the tumour type, stage and lymph node involvement. NETs usually grow slowly, and even with metastases treatment aims to control the disease for a long time.
Is a carcinoid the same as a neuroendocrine tumour?
Yes: “carcinoid” is the older name for a neuroendocrine tumour, still seen in some reports and in the term carcinoid syndrome. Pathologists now write NET and add a grade from G1 to G3, reflecting how fast the tumour cells divide. The grade guides treatment.
Is small intestine cancer hereditary?
Usually not: most of these tumours have no inherited cause. The risk of small bowel adenocarcinoma is higher with Crohn’s disease, coeliac disease and some inherited syndromes, such as familial adenomatous polyposis and Lynch syndrome. If several close relatives have had bowel cancer, tell your doctor, who may suggest genetic counselling.
How AlenMed arranges small intestine cancer treatment
AlenMed starts with the documents: histology report and slides, endoscopy reports, CT or MRI discs and blood tests are translated and sent to surgical and gastroenterology centres across Germany. With a rare tumour, reviewing the histology is especially important: the whole plan depends on the tumour type.
AlenMed then arranges the visa invitation, accommodation and an interpreter, and before discharge helps obtain a follow-up plan for home. AlenMed’s office is in Munich; partner hospitals are all over Germany.
This material is for information only and is not an offer. The treatment plan is decided by the doctor at an in-person consultation.
