From June 1986 to December 1988, 107 patients (median age, 49 years; median performance score, 1) with haematogeneous metastases from breast carcinoma were treated with concomitant radiation and chemotherapy. Overall, 97% of the patients had been pretreated with surgery; 65%, with radiation; and 56%, with hormones. In all, 38% had received adjuvant chemotherapy. Patients with prior palliative chemotherapy were excluded from the study. All patients fulfilled at least two high-risk criteria. Chemotherapy was given according to the EI protocol (4-epirubicin and ifosfamide), and all patients simultaneously received radiation to the main tumour sites. Gastro-intestinal toxicity was moderate (11.1%, WHO grade 4), and bone marrow depression was marked in all cases. After three treatment courses, the overall response rate was 67% [21% complete response (CR), 46% partial response (PR)]. In all, 28% had stable disease (NC) and the rate of progressive disease (PD) was 5%. The median duration of tumour response was 8 months, with 12 months for CRs, 9 months for PRs and 6 months for NCs. The median survival was 13.5 months.

A thirty-eight year-old man, treated medically since 1985 for a chronic pancreatitis, showed a choroidal infiltrate in the superior mid periphery of the left fundus. A thorough systemic examination could not reveal an underlying cause. The differential diagnosis of the lesion included metastasis, intraocular lymphoma and sarcoidosis. Two months later the lesion had increased both on fundoscopy and echography and was accompanied by a serous macular detachment. A choroidal biopsy showed a moderately well differentiated mucinous adenocarcinoma. The primary site could not be determined. The mucinous character is rather suggestive for a gastrointestinal origin. Gastro intestinal choroidal metastases, and more specifically the pancreatic ones, are however rare.

Metastases of malignant melanoma to the small bowel are only rarely seen by the radiologist. In the majority of cases small bowel invasion causes only aspecific symptoms. Gastro-intestinal bleeding is frequently the first specific complaint. Enteroclysis is the most appropriate technique for demonstrating mucosal abnormalities. CT however is not only more sensitive but it also better delineates local and mesenteric involvement.

Gastro-intestinal stromal tumour (GIST) is increasingly recognized as a distinct entity within the group of soft tissue tumours. Mostly, GIST arises from the muscular components of the stromal layer, but the tumour may also originate from the autonomic nerve system, recently designated as gastro-intestinal autonomic nerve tumour (GANT). The majority of GIST is located in the stomach and small intestine; only 4% of GIST is found in the duodenum. Clinical and pathological criteria to differentiate benign from malignant GIST are not well established. Tumour size and mitotic activity are commonly considered as important features, predicting biological behaviour and outcome. It has been suggested that the clinical course of the GANT-type tumours may be more aggressive. We present a case of a radically resected duodenal stromal tumour with benign features, in a young woman, with metastases to the liver and peritoneum occurring 8 years after the initial diagnosis.

Gastro-intestinal stromal tumors are rare and their evolution is dubious. This observation of port site metastasis after laparoscopic resection of a small duodenal stromal tumor would be, to our knowledge, the first case reported in the literature. Several direct and indirect mechanisms were supposed to be involved in the appearance of metastases after laparoscopic surgery, but the risk of dissemination remains badly evaluated on its frequency as well as on its mechanisms.

A 72-year-old man was diagnosed as gastric cancer with pyloric stenosis by an upper gastorintestinal endoscopy for anemia in July 2001. Computed tomography (CT) of the abdomen showed multiple liver metastases. Serum CEA was 6.2 ng/ml. At laparotomy to improve anemia and pyloric stenosis in September 2001, lymphnode metastases invaded the stomach and the pancreatic body. Gastro-jejunostomy was performed without gastrectomy. Oral administration of 100 mg of TS-1 for 28 consecutive days followed by a 14-day rest was given postoperatively. The response assessment of chemotherapy after 1 year was no change (NC) of the primary lesion on endoscopic examination, and liver metastases showed a partial response (PR) on CT. Serum CEA was raised to 86.1 ng/ml in April 2004. The treatment was changed to weekly paclitaxel. The patient died in July 2005. This case with unresectable gastric cancer had been treated by oral administration of TS-1 as an outpatient for 3 years and 7 months.

Gastro-intestinal stromal tumors (GIST), an abdominal sarcoma entity are characterized by a gain-of-function mutation in c-kit proto-oncogen (CD117). Initial treatment should aim at complete removal of the primary tumor (R0 resection) which almost never develops lymphatic metastases. Distant metastatic spread involves mainly the peritoneal cavity and the liver. In patients with metastatic disease, treatment with tyrosinkinase inhibitor imatinib mesylate (Glivec) is indicated and very effective. Systemic chemotherapy and external beam radiation must be considered ineffective. Patients requiring multivisceral resection to remove their primary tumor rapidly develop tumor recurrence and could potentially benefit from preoperative treatment with imatinib. Primary tumors are classified into four risk categories according to their size and mitotic activity. Whether there is an advantage of adjuvant treatment is currently under investigation within international randomized trials. Patients who develop an extensive remission of metastatic disease should be evaluated individually for resection of the tumor remnants. Even resection of single progressive lesions (with newly developed mutations) should be considered in carefully selected patients, if the remaining tumor can be controlled by continued imatinib treatment.

Gastro-intestinal stromal tumors (GIST) form the commonest subgroup of soft tissue sarcomas. They arise in the muscular layer of the esophagus, stomach, small intestines and rectum. Characteristic and important for the assessment of the extent of tumors is the peripheral rim vascularization of primary tumors and metastases. Indications for resection are given for tumors larger than 2 cm in size. Locally advanced GISTs can be advantageously treated with imatinib/sunitinib as neoadjuvant and it is often possible to select a low level of resection for this size of tumor and when the rim area is not hypervascularized. Even in the metastasizing stage surgical treatment can be used for elimination of resistant metastases or for removal of residual tumor tissue in an attempt to counteract secondary tumor progression. The effect of this treatment is currently being tested in a randomized phase III study.

Gastro-entero-pancreatic neuroendocrine tumours (GEP NETs) are unusual. Their incidence, the different tumour types and growth patterns are described. The tumours should be classified according to the WHO 2000 classification and the Tumour Node Metastasis classification according to guidelines from the European Neuroendocrine Tumour Society. Important parameters are localization, size, hormonal secretion, mitotic index, and proliferation index (Ki-67) of the primary tumour. Patients with GEP NET should be referred to as few centres as possible in order to obtain the highest experience and the greatest understanding of these tumours thereby achieving the capacity to offer patients the best possible treatment and to create optimal conditions for research.

Gastro-intestinal stromal tumours are the most common mesenchymal neoplasms of the gastrointestinal tract. Their usual metastatic sites are the liver and the peritoneum, but gastro-intestinal stromal tumours rarely metastasize to the bones. We report the case of a 56-year-old male presenting with bone lesions six years after initial surgical resection. We discuss through this paper the possibilities of management of these lesions and the place of radiotherapy.
