The liver is the main target organ for hematogenous metastases from colorectal cancer, and colorectal liver metastasis is one of the most difficult and challenging situations in the treatment. In order to improve the diagnosis and comprehensive treatment in China, the Guidelines have been edited and revised for seven times since 2008, including the overall evaluation, personalized treatment goals and comprehensive treatments, to prevent the occurrence of liver metastases, increase the local damage rate of liver metastases, prolong long-term survival, and improve quality of life. The revised Guideline version 2025 includes the diagnosis and follow-up, prevention, multidisciplinary team (MDT), surgery and local ablative treatment, neoadjuvant and adjuvant therapy, comprehensive treatment. The revised Guideline emphasizes precision treatment based on genetic molecular typing, especially recommending immune checkpoint inhibitors for dMMR/MSI-H patients, and enriched local treatment methods, such as liver transplantation, yttrium-90 microsphere selective internal radiotherapy, etc. The revised Guideline includes state-of-the-art experience and findings, detailed content, and strong operability.

What are the new contents of the guideline since 2010?A.Patients with primary and non-primary sclerosing cholangitis (PSC) are included in these guidelines for the diagnosis and management of cholangiocarcinoma.B.Define "related stricture" as any biliary or hepatic duct stricture accompanied by the signs or symptoms of obstructive cholestasis and/or bacterial cholangitis.C.Patients who have had an inconclusive report from MRI and cholangiopancreatography should be reexamined by high-quality MRI/cholangiopancreatography for diagnostic purposes. Endoscopic retrograde cholangiopancreatography should be avoided for the diagnosis of PSC.D. Patients with PSC and unknown inflammatory bowel disease (IBD) should undergo diagnostic colonoscopic histological sampling, with follow-up examination every five years until IBD is detected.E. PSC patients with IBD should begin colon cancer monitoring at 15 years of age.F. Individual incidence rates should be interpreted with caution when using the new clinical risk tool for PSC for risk stratification.G. All patients with PSC should be considered for clinical trials; however, if ursodeoxycholic acid (13-23 mg/kg/day) is well tolerated and after 12 months of treatment, alkaline phosphatase (γ- Glutamyltransferase in children) and/or symptoms are significantly improved, it can be considered to continue to be used.H. Endoscopic retrograde cholangiopancreatography with cholangiocytology brushing and fluorescence in situ hybridization analysis should be performed on all patients suspected of having hilar or distal cholangiocarcinoma.I.Patients with PSC and recurrent cholangitis are now included in the new unified network organ sharing policy for the end-stage liver disease model standard.J. Liver transplantation is recommended after neoadjuvant therapy for patients with unresectable hilar cholangiocarcinoma with diameter < 3 cm or combined with PSC and no intrahepatic (extrahepatic) metastases.

The diagnosis of cystic liver disease has made great progress with the advent of enhanced imaging techniques. At the same time, its management has gradually improved over the past few decades, providing the basis for the development of appropriate diagnostic and treatment guidelines. To this end, the European Association for the Study of the Liver has developed clinical guidelines for the diagnosis and treatment of non-infectious cystic liver disease. This guideline put forward recommendations based on an in-depth review of the relevant literature for addressing clinical issues, including the diagnosis and treament of hepatic cysts, hepatic mucocystic tumors, biliary hamartomas, polycystic liver disease, Caroli disease or Caroli syndrome, biliary hamartomas, and peribiliary cyst.

OBJECTIVE: To retrospectively evaluate the safety and efficacy of percutaneous radiofrequency ablation (RFA) in patients with metachronous hepatic metastases arising from pancreatic adenocarcinoma who had previously received curative surgery.MATERIALS AND METHODS: Between 2002 and 2017, percutaneous RFA was performed on 94 metachronous hepatic metastases (median diameter, 1.5 cm) arising from pancreatic cancer in 60 patients (mean age, 60.5 years). Patients were included if they had fewer than five metastases, a maximum tumor diameter of ≤ 5 cm, and disease confined to the liver or stable extrahepatic disease. For comparisons during the same period, we included 66 patients who received chemotherapy only and met the same eligibility criteria described.RESULTS: Technical success was achieved in all hepatic metastasis without any procedure-related mortality. During follow-up, local tumor progression of treated lesions was observed in 38.3% of the tumors. Overall median survival and 3-year survival rates were 12 months and 0%, respectively from initial RFA, and 14.7 months and 2.1%, respectively from the first diagnosis of liver metastasis. Multivariate analysis showed that a large tumor diameter of > 1.5 cm, a late TNM stage (≥ IIB) before curative surgery, a time from surgery to recurrence of < 1 year, and the presence of extrahepatic metastasis, were all prognostic of reduced overall survival after RFA. Median overall (12 months vs. 9.1 months, p = 0.094) and progression-free survival (5 months vs. 3.3 months, p = 0.068) were higher in the RFA group than in the chemotherapy group with borderline statistical difference.CONCLUSION: RFA is safe and may offer successful local tumor control in patients with metachronous hepatic metastases arising from pancreatic adenocarcinoma. Patients with a small diameter tumor, early TNM stage before curative surgery, late hepatic recurrence, and liver-only metastasis benefit most from RFA treatment. RFA provided better survival outcomes than chemotherapy for this specific group with borderline statistical difference.

OBJECTIVE: To review the application of medical imaging in diagnosis and management of fetal hepatic hemangioma. METHODS: Clinical data and imaging findings of 14 cases of fetal hepatic hemangioma, who were diagnosed prenatally and followed up in Women's Hospital of Zhejiang University School of Medicine from February 2014 to September 2018 were retrospective reviewed. RESULTS: The fetal hepatic hemangiomas were single lesions in all 14 cases, and most of them were located in the right lobe of the liver (13/14). Ultrasound images were mainly hypoechoic with heterogeneity, the honeycomb-like or grid-like anechoic regions were presented in 9 lesions and circumferential blood flow was observed with low to moderate blood flow resistance index. MRI findings showed well-defined lesions with low signal intensity on T1WI, and high or slightly high signal intensity on T2WI. Among 14 cases, there were 8 cases of induced labor and 6 cases of continuing pregnancy. In 6 cases of successful delivery, 2 were treated with propranolol, 4 cases were followed-up without treatment. The growth and development of 6 children were normal. The lesions of hepatic hemangioma showed no significant changes in 3 children and were reduced in the other 3 children, of whom the lesion was complete disappeared in 1 case. CONCLUSIONS Fetal hepatic hemangiomas present relatively typical imaging characteristics, and prenatal diagnosis can be made with ultrasound and MRI. If there are no complications, the fetus with hepatic hemangioma can be delivered at full term with a good outcome.

Due to advances in the treatment and diagnosis of cancer, many women survive long after treatment, and therefore express concerns about the impact of estrogen deficiency on their quality of life. Cancer treatment can induce menopause through surgical removal of the ovaries, chemotherapy, or radiation. Women who undergo induced menopause usually experience more sudden and severe menopausal symptoms, including vasomotor symptoms, psychological symptoms, genitourinary symptoms, cardiovascular disease, and osteoporosis. Menopausal hormone therapy (MHT) is especially important in women younger than 40. In this review, we consider the role of MHT after the diagnosis of breast, gynecologic, colorectal, stomach, liver, lung, and hematologic cancers. MHT is advantageous in endometrial cancer type I, cervical squamous cell carcinoma, colorectal cancer, hepatocellular carcinoma, and hematologic malignancies. However, MHT is not recommended for use in breast cancer, endometrial stromal sarcoma, hormone receptor–positive gastric cancer, and lung cancer survivors because it is linked to an increased risk of cancer recurrence. Depending on the type of cancer, clinicians should recommend that cancer survivors receive appropriate MHT in order to reduce vasomotor symptoms and to benefit from its positive effects on the cardiovascular and skeletal systems.

Primary neuroendocrine tumors originating from the extrahepatic bile duct are rare. Among these tumors, large cell neuroendocrine carcinomas (NECs) are extremely rare. A 59-year-old man was admitted to Sanggye Paik Hospital with jaundice that started 10 days previously. He had a history of laparoscopic cholecystectomy, which he had undergone 12 years previously due to chronic calculous cholecystitis. Laboratory data showed abnormally elevated levels of total bilirubin 15.3 mg/dL (normal 0.2–1.2 mg/dL), AST 200 IU (normal 0–40 IU), ALT 390 IU (normal 0–40 IU), and gamma-glutamyl transferase 1,288 U/L (normal 0–60 U/L). Serum CEA was normal, but CA 19-9 was elevated 5,863 U/mL (normal 0–37 U/mL). Abdominal CT revealed a 4.5 cm sized mass involving the common bile duct and liver hilum and dilatation of both intrahepatic ducts. Percutaneous transhepatic drainage in the left hepatic duct was performed for preoperative biliary drainage. The patient underwent radical common bile duct and Roux-en-Y hepaticojejunostomy for histopathological diagnosis and surgical excision. On histopathological examination, the tumor exhibited large cell NEC (mitotic index >20/10 high-power field, Ki-67 index >20%, CD56 [+], synaptophysin [+], chromogranin [+]). Adjuvant concurrent chemotherapy and radiotherapy were started because the tumor had invaded the proximal resection margin. No recurrence was detected at 10 months by follow-up CT.

Hemangioendothelioma is a rare vascular tumor with involvement of the liver, brain, long bones, and lung. Among the 6 histological subtypes, epithelioid hemangioendothelioma (EHE) is the most aggressive. Its occurrence in the mediastinum is quite rare, and very few cases have been documented. The reported cases in the literature have described difficulties in the preoperative diagnosis due to the unusual histological appearance of the tumor. Immunohistochemistry remains the mainstay for a definitive diagnosis. Due to its low incidence, there is no standard treatment for mediastinal EHE, but curative resection is the preferred treatment option where possible, with chemotherapy used as an adjuvant treatment or in cases of widespread inoperable disease. The present case study describes an aggressive EHE occurring in an 18-year-old woman in the anterior mediastinum.

OBJECTIVE: To explore the prognostic factors of patients with unresectable liver metastasis colorectal cancer after failed conversion chemotherapy. METHODS: A retrospective, case-controlled study was performed. Study subjects were 105 patients who were diagnosed with synchronous liver metastasis colorectal cancer after failed chemotherapy (metastasis evaluated as unresectable after the conversion chemotherapy) at Xinhua Hospital, Shanghai Jiaotong University from January 2012 to December 2015. Overall survival(OS) was retrospectively analyzed using Kaplan-Meier method. Log-rank test was used to compare survival among groups. Univariate and multivariate analysis was conducted for prognosis using Cox regression model. RESULTS: Of 105 cases,70 were male and 35 were female with median age of 60 years old. Twenty-one patients had right colon cancer, 41 had left colon cancer, 42 had rectal cancer and 1 had synchronous cancers(sigmoid colon and rectum). One hundred and two (97.1%) patients were cT3-4 and 90 patients were cN+ (imaging diagnosis). Eighty-nine (84.8%) patients were loaded with 2 or more liver metastases with the median maximum diameter of 48.3 mm. The patients were followed up for 3 to 43 months from the day of diagnosis. The median OS was 11 months (interquartile range, 8-18). The median OS of patients with cN0, cN1 and cN2 stage was 17, 13 and 10 months, respectively(P=0.026). The median OS of patients with single lesion, 2-3 lesions, 4-10 lesions and more than 10 lesions was 15, 15, 17 and 9 months, respectively (P=0.002). OS of patients with maximum diameter of liver metastatic lesion ≤ 50 mm, 51-100 mm and >100 mm was 15, 10 and 8 months, respectively(P=0.003). The median OS of patients with chemotherapy response of partial response (PR), stable disease (SD) and progressive disease (PD) was 17, 14 and 8 months, respectively(P<0.001). OS was 17 months in patients receiving second line chemotherapy and was 10 months in those without second line chemotherapy (P<0.001). OS in patients undergoing primary tumor resection was 13 month and in those without primary tumor resection was 9 months; the difference was not significant (P=0.060). Multivariate analysis showed that cN2(HR=2.115, 95%CI:1.089-4.109, P=0.027), the maximum diameter of liver metastatic lesion more than 100 mm (HR=3.112, 95%CI:1.455-6.657, P=0.003), chemotherapy response of PD (HR=4.435, 95%CI:2.506-7.533,P<0.001) and without second line chemotherapy(HR=4.432,95%CI:2.186-8.986, P=0.010) were independent prognostic factors. CONCLUSIONS For patients with unresectable liver metastasis from colorectal cancer after failed conversion chemotherapy, prognostic factors include cN2, the maximum diameter of liver metastatic lesion, chemotherapy response and second line chemotherapy. Whether the resection of primary tumor can prolong OS further study.
