Clinical presentation and treatment of gastric metastasis from other malignancies of solid organs.

ABSTRACT: The aim of the present study was to analyze the clinicopathologic features and treatment outcomes of gastric metastasis from other malignancies of solid organs. A review was conducted of patients with metastatic tumors in the stomach from other malignancies of solid organs detected endoscopically at the Department of Surgery, Kochi Medical School, from January 1991 to December 2015. Seven patients (four men and three women), with a median age of 64 years (range, 42-71 years), had metastatic gastric tumors. Median tumor size was 7.3 cm (range, 2.5-12.0 cm). The primary malignancy leading to metastatic tumors in the stomach was esophageal cancer in three patients, breast cancer in two patients, renal cell carcinoma in one patient, and ovarian cancer in one patient. Gastric metastasis presented as solitary lesions in six patients and as multiple lesions in one patient. Four patients had solitary gastric metastasis, whereas three had multiple metastases in other organs. The median tumor size was significantly smaller in patients with solitary rather than multiple metastases (4.6 vs. 12.0 cm, respectively; P=0.038). Three patients received systemic therapy and four underwent surgical resection of the metastatic tumor, and of these, only one was alive 58 months after surgery. Clinicians should be aware of the possible existence of metastatic gastric cancer, especially in breast carcinoma and esophageal cancer. Surgical resection may considerably improve patients' quality of life, and could be of benefit when there is a risk of bleeding and/or a solitary metastasis.

Project description:AIM:GDF-15 is an established cardiovascular risk marker but is equally implicated in tumour biology. Elevated levels of GDF-15 have indeed been observed in distinct tumour entities. This study aimed to explore the relation of GDF-15 to other cardiac biomarkers and the general association of GDF-15 on prognosis in an unselected cohort of treatment-naïve cancer patients. METHODS:We prospectively enrolled 555 consecutive patients at time of diagnosis of malignant disease prior receiving anticancer therapy. Plasma GDF-15 concentrations were determined alongside other cardiac and routine laboratory markers. All-cause mortality was defined as primary endpoint. RESULTS:GDF-15 levels were 338 ng/L (IQR:205-534) for the total cohort, and values were comparable for different tumour entities except breast cancer. Metastatic disease was characterized by higher plasma GDF-15 [435 ng/L (IQR:279-614) vs 266 ng/L (IQR:175-427), P < .001]. GDF-15 correlated positively with inflammatory status reflected by CRP, SAA and IL-6 [r = .31, P < .001, r = .23, P < .001 and r = .14, P = .002] and cardiac biomarkers as NT-proBNP, hsTnT, MR-proADM and CT-proET-1 [r = .46; r = .46; r = .59 and r = .50; P < .001 for all]. GDF-15 was significantly associated with all-cause mortality after multivariate adjustment [adj.HR for ln(GDF-15) 1.78, 95%CI:1.47-2.16, P < .001]. There was a significant interaction between solid and haematological malignancies with loss of association of GDF-15 with outcome in myelodysplastic and myeloproliferative disease. CONCLUSIONS:Elevated plasma GDF-15 is associated with progressing disease severity and poor prognosis in solid tumours of treatment-naïve cancer patients. GDF-15 increase is accompanied by worsening systemic inflammation and a subclinical functional impairment of different organs including the heart. GDF-15 represents a promising target for our pathophysiologic understanding in cardio-oncology linking conditions of both cardiac and neoplastic disease.
