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.

OBJECTIVEThis review discusses the current status and progress in studies on gastric cancer with liver metastasis (GCLM), involving the routes, subtypes, and prognosis of GCLM; the genes and molecules associated with metastasis; the feasibility and value of each imaging modality; and current treatment options.

DATA SOURCESThe data used in this review were mainly from Medline and PubMed published in English from 2005 to August 2010. The search terms were "gastric cancer" and "liver metastasis".

STUDY SELECTIONArticles regarding the characteristics, diagnostic modalities, and various therapeutic options of GCLM were selected.

RESULTSThe prognosis of GCLM is influenced by the clinicopathological characteristics of primary tumors, as well as the presence of liver metastases. Improved understanding of related genes and molecules will lead to the development of methods of early detection and targeted therapies. For the diagnosis of GCLM, each imaging modality has its relative benefits. There remains no consensus regarding therapeutic options.

CONCLUSIONSEarly detection and characterization of liver metastases is crucial for the prognosis of gastric cancer patients. Multidisciplinary team discussions are required to design optimal treatment strategies, which should be based on the clinicopathological characteristics of each patient.

Extrahepatic metastasis in patients with hepatocellular carcinoma (HCC) occurs frequently. The most common site of metastasis is the lung, followed by regional lymph nodes and bones. However, gastrointestinal metastasis of HCC is a rare condition and solitary polypoid metastatic lesion on stomach without any evidence of direct invasion from primary mass is very rare. These metastatic lesions are usually asymptomatic, and most are discovered at postmortem examination or are found incidentally during laparotomy. The choice of treatment for gastrointestinal metastatic lesion of HCC includes surgery, transarterial chemoembolization, and local injection but the treatment is often difficult and unsuccessful. We report a case of 69 years old man who presented disappearance of a polypoid metastatic lesion of HCC on the gastric fundus by transarterial chemoembolization.

In recent years there have been great developments in the diagnosis and comprehensive treatment of colorectal cancer liver metastases (CRLM). Guidelines for the Diagnosis and Comprehensive Treatment of Colorectal Cancer Liver Metastases were compiled to standardize and improve the diagnosis and treatment outcomes in China. This paper summarizes the updated content in the Guideline (V.2013). We should conduct gene testing related to CRLM to guide individual treatment, emphasize the role of the multidisciplinary team, and select molecular targeted drugs reasonably. In addition, we discuss the operative timing of CRLM, minimally invasive operation and regional therapy of liver metastases.

Colorectal cancer is one of the most common malignancies in human, and colorectal liver metastasis (CLM) is one of the most common leading causes of death in these patients. In recent years, along with the update of diagnosis and treatment concept and advancement of operative technique, more and more patients with CLM get surgical treatment opportunities and the outcomes are improved. In clinical practice of CLM, depending on evidence-based medicine, standardized diagnosis and treatment is particularly important, which includes diagnosis and treatment by multidisciplinary team, accurate evaluation of the resectability of CLM, standardized surgical resection and essential comprehensive treatment.

The liver is the most common anatomical site for hematogenous metastases of colorectal cancer, and colorectal liver metastases is one of the most difficult and challenging points in the treatment of colorectal cancer. In order to improve the diagnosis and comprehensive treatment in China, the Guidelines have been edited and revised for several times since 2008, including the overall evaluation, personalized treatment goals and comprehensive treatments, to prevent the occurrence of liver metastases, improve the resection rate of liver metastases and survival. The revised Guideline includes the diagnosis and follow-up, prevention, MDT effect, surgery and local ablative treatment, neoadjuvant and adjuvant therapy, and comprehensive treatment, and with advanced experience, latest results, detailed content, and strong operability.

Hepatocellular carcinoma (HCC) is a major health problem worldwide, and it has a poor prognosis. Extrahepatic metastasis from HCC is not unusual, with direct invasion representing the main spreading mode. Sites that are frequently involved are the lung, bone, and lymph nodes. There are few reports of HCC invading the distant gastrointestinal tract, especially hematogenously. Herein we report a case of sigmoid colon metastasis from HCC. The patient was diagnosed with HCC and treated with transcatheter arterial chemoembolization (TACE). Eighteen months after TACE the patient presented with abdominal pain on the left lower quadrant, and a CT scan showed an enhanced mass on the sigmoid colon. Immunohistochemical staining revealed that a tumor cell was positive for polyclonal carcinoembryonic antigen and weakly positive for hepatocyte antigen, supporting the diagnosis of HCC metastasis. The patient underwent anterior resection for the metastatic HCC.

OBJECTIVETo investigate the prognostic factors of colorectal cancer patients with liver metastasis in order to provide reference for clinical practice.

METHODSClinicopathological and follow-up data of 264 cases of colorectal liver metastasis in our department from January 1997 to January 2012 were analyzed retrospectively. Among these 264 patients, 217 underwent primary colorectal cancer resection, 33 underwent combined resection of primary colorectal lesion plus liver metastasis, and 14 received stoma creation alone. Besides, 197 patients received adjuvant chemotherapy, 14 received adjuvant radiotherapy, and 42 underwent interventional treatment. Clinicopathological features and treatment scheme affecting prognosis were analyzed and prognostic stratification analysis was performed according to emergence time of liver metastasis (synchronous or metachronous).

RESULTSOf 264 patients, 1-, 3-, and 5-year overall survival rates were 77.0%, 31.7%, and 14.0%; median survival time was 25 months; 1-, 3-, and 5-year survival rates of synchronous colorectal liver metastasis were 68.8%, 22.3%, and 7.7%; 1-, 3-, and 5-year survival rates of metochronous colorectal liver metastasis were 95.8%, 49.0%, and 21.3%, whose difference was statistically significant (P<0.05). Multivariate analysis showed that primary tumor differentiation, CEA level, adjuvant chemotherapy, and radical resection were independent prognostic factors of colorectal cancer patients with liver metastasis (all P<0.05), while primary tumor differentiation, CEA level, and radical resection were independent prognostic factors of synchronous liver metastasis (all P<0.05), and primary tumor location and CEA level were independent prognostic factors of metachronous liver metastasis (all P<0.05).

CONCLUSIONSRadical operation and adjuvant chemotherapy should be emphasized for colorectal liver metastasis, especially for synchronous colorectal liver metastasis. Simple resection of primary tumor can not improve the overall survival of patients with colorectal liver metastasis.

Spontaneous regression of hepatocellular carcinoma (HCC) is extremely rare. We report a case of 67-year-old man having HBV-associated HCC with multiple lung metastases which regressed spontaneously. The patient had single liver mass and received surgical resection. The mass was confirmed as HCC histopathologically. Nine years after surgical resection, a 3.3 cm sized recurred HCC was detected on the resection margin in CT scan. Transarterial chemoembolization (TACE) was performed 3 times, and lung metastases developed thereafter. The patient received 2 more sessions of TACE, however, metastatic lung nodules were in progress very rapidly. We decided to stop TACE and followed the patient regularly without any anti-cancer treatment. Nine months after development of lung metastasis, the size and number of metastatic lung nodules decreased and were not detected anymore after 14 months. Serum alpha-fetoprotein levels also decreased to normal range and no viable tumor was noted in the liver. The patient is still alive 12 years after the first diagnosis of HCC and 16 months after lung metastasis developed.

This manuscript describes an unusual case of rapid intra-hepatic dissemination of hepatocellular carcinoma with pulmonary metastases occurring 1 month after combined chemoembolization and radiofrequency ablation. Inferior vena cava and portal vein invasion tumor thrombus was also detected, possibly accounting for the mechanism of disease dissemination route of disease.
