Objective:To investigate the clinical characteristics and prognosis of Philadelphia (Ph) chromosome-positive chronic myeloid leukemia (CML) patients with additional chromosomal abnormalities.Methods:The data of 351 CML patients with Ph-positive in the Affiliated Hospital of Qingdao University from January 2009 to January 2019 were retrospectively analyzed. The bone marrow chromosomal karyotype analysis of all patients was performed by using R-banding technique. The clinical characteristics and karyotype of Ph-positive CML patients with additional chromosomal abnormalities at initial diagnosis were summarized, and Kaplan-Meier was used to analyze the differences in overall survival (OS) of patients with different karyotypes.Results:Among 351 patients with Ph-positive CML, 32 (9.1%) cases had variant translocation. At initial diagnosis, 47 cases had additional chromosomal abnormalities including 29 cases in chronic phase accounting for 9.15% (29/317) of all patients in chronic phase, 3 cases in accelerated phase accounting for 25.00% (3/12) of all patients in accelerated phase, 15 cases in blast crisis accounting for 68.18% (15/22) of all patients in blast crisis; there was a statistically significant difference in the chromosomal abnormalities rate of all different phases ( χ2=50.799, P<0.05). Among 47 Ph-positive CML patients with additional chromosomal abnormalities, 13 patients had complex karyotypes with more than 3 additional chromosomal abnormalities, the proportion of complex karyotypes in chronic phase, accelerated phase and blast crisis was 13.79% (4/29), 33.33% (1/3) and 53.33% (8/15), respectively, and the difference was statistically significant ( χ2=9.26, P<0.05). The study showed that the most common additional chromosomal abnormalities in chronic phase were double Ph (48.28%, 14/29) and -Y (10.34%, 3/29), while the most common chromosomal abnormalities in the blast crisis were +8 (26.67%, 4/15) and double Ph (26.67%, 4/15). Kaplan-Meier survival analysis showed that at initial diagnosis the OS time of patients with additional chromosomal abnormalities was worse than that of those with the non-additional chromosomal abnormalities group ( χ2 = 61.138, P<0.05). The OS of patients with complex karyotypes for Ph - positive CML patients with additional chromosomal abnormalities at initial diagnosis was worse than that of patients with non-complex karyotypes, and the difference was significant ( χ2 = 4.945, P < 0.05). Conclusions:The additional chromosomal abnormalities is closely related to the progression of CML, and the prognosis of CML patients with additional chromosomal abnormalities is poorer than that of patients with only Ph translocation. Moreover, the more complex the additional chromosomes are, the more likely blastic changes are, and the poorer prognosis. And additional chromosomeal abnormalities during the treatment of CML patients may also lead to the progression of blastic changes.

Malignant obstructive jaundice is caused by direct invasion or compression of the biliary tract by malignant tumors of the bile duct, pancreas and other systems. Patients are often accompanied by symptoms such as malnutrition, low immune function, and organ damage. The treatments of active preoperative biliary drainage and reasonable reinfusion combined with enteral nutrition can help improve the safety of patients during the perioperative period, reduce postoperative complications, and improve the life quality of patients. This article reviewed the research progress of preoperative biliary drainage, bile recycling methods and precautions in patients with malignant obstructive jaundice, aiming to provide reference for clinical diagnosis and treatment practice.

Surgical resection is one of the important means to achieve long-term survival for patients with liver malignant tumor. However, most of the liver malignant tumor has been diagnosed in the middle and late stage, and lose the chance of surgical treatment. For these patients who have lost the chance of surgery, some surgeons have proposed the concept of planned liver resection, which is to reduce tumor stage and increase future liver remnant (FLR) in a planned way, so as to improve the safety of surgery and prolong the survival time of patients after surgery. For patients with FLR insufficiency after prior evaluation or/and treatment, the technique of hepatic hyperplasia is an important part of planned hepatectomy, that is, to effectively increase FLR in a short period of time by various means. Portal vein ligation (PVL) and portal vein embolization (PVE), associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) and liver venous deprivation (LVD) are three main techniques for hepatic hyperplasia. This article reviews the principle, effect and safety of three liver augmentation techniques.

OBJECTIVETo study the relationship between the expression of soluble drug resistance-related calcium-binding protein (sorcin) gene and the clinical multidrug resistance in acute leukemia (AL).

METHODSA semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) was used to investigate the transcription levels of the human sorcin gene in 95 AL patients and 27 controls.

RESULTSSorcin gene expression was significantly higher in AL patients than in normal contrls (P < 0.001), and higher in relapsed/refractory acute myeloid leukemia (AML) patients than in those newly diagnosed or in complete remission. Sorcin gene overexpression was significantly lower in non-resistant patients than in resistant ones (P < 0.001). CR rates of these two groups were 20.0% and 80.0%, respectively. Sorcin gene expression was higher in AML-M(5) patients than M(2), M(3), M(4) patients.

CONCLUSIONSorcin gene overexpression is significantly associated with clinical multidrug resistance and prognosis, it is one of the indicators for predicting prognosis of AL patients.

OBJECTIVETo study the relationship between soluble resistance-related calcium-binding protein (sorcin) gene and multidrug resistance gene (mdr1), and their significance in clinical drug resistance and prognosis of acute myeloid leukemia (AML).

METHODSAmplification of sorcin gene and mdr1 gene in K562/A02 cell detected by Northern blot, were monitored by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) in 65 AML patients and 27 normal controls, with their relationship and clinical outcame analyzed.

RESULTSThe amplification of sorcin gene and mdr1 gene in AML patients were significantly higher than that in the normal control, which were related to clinical drug resistance and prognosis. The amplification of sorcin gene was related to the amplification of mdr1 gene in the two groups. The clinical drug resistance incidence rate and complete remission rate were 92.9% and 7.1% in sorcin(+)/mdr1(+) group. They were 8.6% and 91.4% in the sorcin(-)/mdr1(-) group (P < 0.001).

CONCLUSIONThe co-amplification of sorcin and mdr1 gene can be taken as a good indicator of clinical drug resistance and prognosis of AML.

Surgical resection is the first choice for liver cancer therapy.In order to transform the unresectable part into resectable one,surgeons manage to ensure adequate liver reserves by making the wanted liver tissue become hypertrophy and let the unwanted one become atrophy.However,though ALPPS (associating liver partition and portal vein ligation for staged sepatectomy) as an alternative operation plan in its initial developing stage now becomes a hot topic,it is still under great controversy.The author believes that it is imperative to draw up a personalized plan and carry out a strict and reasonable multicenter-clinical trial for those patients to get an opportunity to conduct a safe and effective operation.

Objective:To evaluate the safety and clinical efficacy of transcatheter arterial chemoembolization (TACE) combined with portal vein embolization (PVE) and percutaneous microwave ablation liver partition with PVE for planned hepatectomy in patients with hepatocellular carcinoma (HCC) with insu-fficient remnant liver volume.Methods:The clinical data of 51 patients with initially unresectable HCC due to insufficient remnant liver volume admitted to Zhejiang Provincial Tongde Hospital and Zhejiang Provincial People’s Hospital from January 2014 to December 2021 were retrospectively analyzed, including 37 males and 14 females, aged (56.7±11.2) years old. Patients were divided into two groups according to the treatment prior to hepatectomy: percutaneous microwave ablation liver partition combined with PVE (AP group, n=12) and TACE with PVE (TP group, n=39). Patients who successfully underwent planned hepatectomy in the above two groups were marked as resectable AP group ( n=10) and the resectable TP group ( n=29), respectively. Clinical data including the waiting time for surgery and the incidence of complications were analyzed. Patients were followed up by telephone or outpatient review. Kaplan-Meier and log-rank analysis were used for survival comparison. Results:The FLR growth rate was higher in AP group [76.5% (65.3%, 81.6%)] than that in TP group [31.4% (28.2%, 41.9%), P<0.01]. The waiting time for planned hepatectomy in the resectable AP group was 12.0 (11.3, 14.5) d, shorter than that in the resec-table TP group [21.0 (15.0, 29.0) d, P<0.05]. The incidence of postoperative complications was higher in the resectable AP group than that in the resectable TP group [80.0% (8/10) vs. 27.6% (8/29), P<0.05]. There was one perioperative death in the resectable AP group. The survival rate after PVE was lower in AP group than that in TP group, and the survival rate after hepatectomy was also lower in the resectable AP group than that in the resectable TP group (all P<0.05). Conclusion:For HCC patients with insufficient FLR, TACE combined with PVE is a safe and effective method for enlargement of liver remnant, whereas percutaneous microwave ablation liver partition with PVE showed a poor prognosis, despite the higher rate of FLR enlargement and shortened the waiting time for planned hepatectomy.

OBJECTIVETo compare the efficacy and toxicity of the chemotherapeutic regimen containing pirarubicin and mitoxantrone on the treatment of relapsed or refractory acute myeloid leukemia (AML) in adults.

METHODSIn this open prospective multicentre study, we randomly assigned patients with relapsed or refractory AML to receive TAE regimen (pirarubicin+cytarabine+etoposide) versus MAE regimen (mitoxantrone + cytarabine + etoposide). The efficacy and toxicity were compared between the two groups.

RESULTS56 patients entered this clinical trial. The complete remission (CR) rate on TAE arm was 79.0% versus 55.6% on MAE arm with the overall response (OR) rates of 86.8% versus 88.9%, respectively. The CR was higher on TAE arm (P=0.035) but with no significant difference between the two groups regarding the overall response (OR) rate. The regimens were well tolerated in both groups. Hematologic and non-hematologic toxicity were similar except relatively lower the mean dosage of G-CSF, red blood cells and platelets transfusion on TAE arm. No significant differences were seen between the two groups regarding the overall survival and relapse free survival rates.

CONCLUSIONTAE regimen might be an effective salvage therapy in patients with relapsed or refractory AML.
