ABSTRACT

We report a case of patient who is alive 10 years after total gastrectomy and partial liver resection for gastric cancer and liver metastasis, respectively. The patient is 69-year-old man who was examined in another hospital for nausea, tarry stool, and weight loss. Diagnosis by stomach fluoroscopy revealed gastric cancer and he was admitted to our hospital in September 2002. Computed tomography (CT) scan and ultrasonography (US) revealed liver metastasis in S7. Distant metastases were not detected. The patient underwent distal gastrectomy, transverse colon partial resection, and a hepatic partial resection in October 2002. Pathological findings showed SI, N1, and M1. Though adjuvant chemotherapy was given, a local recurrence was detected in the liver in February 2003. Hepatic arterial infusion (HAI) was started in April 2003. After 8 courses, HAI was discontinued because of hepatic artery obstruction. No additional distant metastases were found. Therefore, transdiaphragmatic radiofrequency ablation (RFA) was performed by thoracotomy. Currently, the patient is treatment free and remains alive after 10 years with no recurrence.

ABSTRACT

OBJECTIVE: Because diffusion-weighted imaging (DWI) can predict the prognosis of patients with oesophageal squamous cell carcinoma (ESCC), we hypothesised that apparent diffusion coefficient (ADC) values might be correlated with the collagen content and tumour angiogenesis. The purpose of this study was to determine the correlation between ADC values of ESCC before treatment and oesophageal tumour stroma and angiogenesis. METHODS: Seventeen patients with ESCC were enrolled. The ADC values were calculated from the DWI score. Seventeen patients who had undergone oesophagectomy were analysed for tumour stroma, vascular endothelial growth factor (VEGF) and CD34. Tissue collagen was stained with azocarmine and aniline blue to quantitatively analyse the extracellular matrix in cancer stroma. Tissues were stained with VEGF and CD34 to analyse the angiogenesis. RESULTS: The ADC values decreased with stromal collagen growth. We found a negative correlation between the tumour ADC and the amount of stromal collagen (r = -0.729, P = 0.001), i.e. the ADC values decreased with growth of VEGF. We also found a negative correlation between the ADC of the tumours and the amount of VEGF (r = 0.538, P = 0.026). CONCLUSION: Our results indicated that the ADC value may be a novel prognostic factor and contribute to the treatment of oesophageal cancer. KEY POINTS: • Magnetic resonance apparent diffusion coefficient values inversely indicate tumour stromal collagen • There is also negative correlation between ADCs and vascular endothelial growth factor • ADC values may contribute to the treatment of oesophageal cancer.
