Colorectal cancer (CRC) is the third common malignant tumor worldwide and the second cause of cancer-related death. Liver metastasis is the main cause of mortality in colorectal cancer. Exploration of the mechanism and the processes of liver metastasis, and therapeutic intervention are important to improve the overall survival and the quality of life of patients with colorectal cancer. Biomarkers has been one of the hot spots in the study of colorectal cancer. More and more biomarkers are being found and warrant further study.

Gastric cancer with liver metastasis (GCLM) is the leading cause of death in patients with advanced gastric cancer. Multiple metastasis was common in GCLM and usually complicated with lesions outside the liver, especially peritoneal metastasis. Most of liver metastasis lesions could not be resected radically. Currently, main treatments for GCLM included radical operation, palliative resection of gastric cancer, ablation of metastatic lesions, intervention and systemic chemotherapy. Based on the current progress in the treatment for GCLM and our clinical experience, the general status of patients, the type of gastric cancer and the degree of liver metastasis should be analyzed, and a cooperative multidisciplinary team (MDT) should be applied to conduct and to choose active and suitable comprehensive treatment for GCLM patients based on individualized therapy principle.

OBJECTIVETo improve the diagnosis and treatment of far advanced prostate cancer without clinically detectable bone metastasis.

METHODSCancer metastatic lesions were found in the liver and lungs respectively of two patients on routine medical examination, and only an abnormally elevated level of the serum prostate specific antigen (PSA) was observed in the following system examinations. The patients were diagnosed as having prostate cancer by prostate biopsy. MRI showed a discontinued prostate capsule, and ECT revealed no bone metastasis. Diagnostic treatment was conducted by giving LHRHa combined with antiandrogens. One of the patients underwent surgical castration at 12 months, and both received intensity modulated radiation therapy (80 Gy) at 15 and 18 months, respectively.

RESULTSThe metastatic lesions in the liver and lungs of the patients were either absent or significantly reduced after treated by maximal androgen blockade for 3 months, and all disappeared after 6 months'treatment, with the PSA level stabilized at less than 0.02 microg/L in one patient, and around 0.5 microg/L in the other. Antiandrogen treatment was suspended after radiotherapy. The results of liver, lung and bone scanning were normal during the 12-month follow-up, and the PSA level was below 1.0 microg/L.

CONCLUSIONRemote metastasis of prostate cancer may occur in ectosteal organs first, which deserves special attention. A combination of different treatment methods promises satisfactory results.

The study examined the association between calcified liver metastases and the histopathology of the primary colorectal carcinoma in Chinese. The clinical, pathological and CT data were retrospectively analyzed in 210 patients (mean age: 54.2 years) with liver metastases from colorectal carcinoma. Plain CT scanning and contrast-enhanced scanning were performed in all the patients. For the contrast-enhanced examination, iohexol was injected by using a high pressure syringe at a flow rate of 2.5-3.0 mL/s. The arterial phase lasted approximately 25 s and the portal venous phase about 60 s. All patients had no history of chronic liver diseases and had never received interventional treatments. χ(2)-test was used to analyze the rate of calcification in the liver metastasis from colorectal cancer of different differentiation degrees. Among the 210 cases of liver metastases, 22 patients (10.5%) were found to have calcified liver metastases on CT scan. Two patients with calcified liver metastasis received lumpectomy and developed calcification in recurrent tumors. Another two patients had calcification in newly developed tumor masses. And the calcification in the newly developed masses was similar to that of their primary counterparts in terms of morphology and distribution. On the enhanced CT scan, the tumors exhibited no enhancement during hepatic arterial phase and showed slight rim enhancement during portal venous scan in the 22 cases. The calcification became obscure on contrast-enhanced scans. Histopathologically, the primary tumors were well-differentiated adenocarcinoma in 6 cases, moderately-differentiated adenocarcinoma in 10, poorly-differentiated adenocarcinoma in 4 and mucinous adenocarcinoma in 2 among the 22 cases. No statistical correlation was noted between the incidence of calcified liver metastasis and the pathological subtypes and differentiation degrees of the primary colorectal carcinoma. It was concluded that calcified liver metastases may result from colorectal adenocarcinomata of different differentiation degrees or mucinous adenocarcinomata in Chinese population. There is no correlation between calcification of liver metastases and the pathological subtype of the primary colorectal carcinoma in Chinese, which is different from the findings that calcified metastases were associated with colorectal mucinous adenocarcinoma in other ethnic groups.
