短程间歇预防性给予重组人血小板生成素治疗肺癌化疗诱导的严重血小板减少的疗效

Objective To evaluate the efficacy of short-term intermittent prophylactic use of a recombinant human thrombopoietin ( rhTPO) in chemotherapy-induced severe thrombocytopenia in lung cancer patients. Methods 24 advanced non-small cell lung cancer ( NSCLC) patients who experienced severe thrombocytopenia in the last chemotherapy cycle received prophylactic rhTPO treatment in the next chemotherapy cycle (prophylactic treated cycle, PTC). rhTPO was given subcutaneously 300 U ·kg-1· d-1 on days 2, 4, 6, and 9 after the initiation of chemotherapy. Platelet count was monitored and compared with that in the previous treatment cycle (control cycle, CC ). Results The lowerest platelet count in the prophylactic rhTPO cycle was significantly higher than that in control cycle [(56 ± 16)×109/L vs. ( 28 ± 13) × 10'/L, P < 0.001]. The duration of thrombocytopenia was also shortened by the prophylactic rhTPO [(8±2) d vs. (12 ±3) d, P<0.001]. The area under curve (AUC) of platelet count (21 days) was significantly increased [(3517 ± 685 ) x 109/L vs. (2063 ± 436)×109/L, P < 0. 001]. The time to platelet nadir and peak was not affected. Conclusion Prophylactic use of rhTPO can attenuate the severity and shorten the duration of chemotherapy-induced thrombocytopenia in lung cancer patients.     

Evaluation of the safety and efficacy of glucocorticoid therapy for hyperbilirubinemia in patients with hepatocellular carcinoma who have undergone transcatheter arterial chemoembolization

Objective The aim of this study was to analyze the safety and efficacy of glucocorticoid treatment for hyperbilirubinemia in patients with hepatocellular carcinoma(HCC)who have undergone transcatheter arterial chemoembolization(TACE).Methods We conducted a retrospective analysis of the clinical data of 198 patients with HCC who were admitted to The Fifth Medical Center of PLA General Hospital from June 2014 to August 2019 and underwent TACE therapy.The patients were divided into glucocorticoid(GCC)treatment group and control group.Standard liver-protecting procedures were used in both groups.The treatment group also received intravenous injections of methylprednisolone sodium succinate for 3–5 days.Reduction in bilirubin concentration,mean duration of hospitalization,and complications were compared between the two groups to investigate the safety and efficacy of GCCs for treatment of hyperbilirubinemia after TACE treatment.Results Bilirubin concentrations were significantly lower in the treatment group than in control group on days 3 and 5 after GCC/conventional liver-protecting treatment(P<0.05).The treatment group had significantly shorter durations of total post-surgery hospitalization,and recovery time than the control group(14.5±4.6 days vs.17.5±6.6 days,P<0.001;9.2±3.3 days vs.11.8±5.4 days,P=0.001;7.0±3.3 days vs.9.3±4.6 days,P<0.001).No GCC-associated complications were detected in the treatment group.Conclusion Short-term use of GCCs to treat hyperbilirubinemia in patients with HCC who have undergone TACE is safe and associated with rapid decline in bilirubin concentration and shorter hospital stay compared with patients who did not receive GCCs.

围手术期应用西米替T对结直肠癌TIL浸润及HLA-DR表达的影响

Objective： It has been shown in our previous study that cimetidine （CIM） can boost the hosts＇ cellular immunity in patients with gastrointestinal cancer. This study was conducted to evaluate CIM＇s effects on tumor infiltrating lymphocytes （TIL） and HLA-DR expression in tumor stroma in colorectal cancer （CRC）, so as to investigate its role in local immune response at the tumor site in CRC. Methods： Forty-nine CRC patients were randomized into treatment group of 25 patients who took CIM 7 days before curative surgery till the operation day, and control group of 24 patients who received similar treatment except for CIM intervention. TIL responses and HLA-DR expression were studied on tumor tissues taken before and after surgical resection. Results： The percentage of significant TIL response was increased from 32% （8/25） to 76% （19/25） （P〈0.005） in the CIM treatment group, whereas there were no significant changes in TIL response in the control group [25% （6/24） at recruitment vs. 33% （8/24） at operation, P〉0.50]. Moreover, the percentages of HLA-DR expression were increased from 36% （9/25） to 72% （18/25） in the CIM treatment group, but there were no significant differences in HLA-DR expression in the control group [41.7% （10/24） before resection vs 45.8% （11/24） after resection, P〉0.50]. Conclusion： CIM used before surgery might promote TIL responses and increase the HLA-DR expression in stroma cells in CRC patients, leading to enhanced host immunity against tumor.     

卵巢上皮性癌和血小板计数增高相关性分析

Objective: To evaluate the clinical significance of platelet (PLT) count in epithelial ovarian cancer, and to inves-tigate the correlation between thrombocytosis and the incidence of epithelial ovarian cancer. Methods: We evaluated 220 epithelial ovarian tumor patients divided into early stage epithelial ovarian cancer group (n = 80), advanced stage epithelial ovarian cancer group (n = 50) and benign ovarian tumor group (n = 90) as controls, who underwent primary surgical treatment. Three groups were evaluated with the relationship between platelet counts and preoperative and postoperative CA125, histo-pathology, abdominal edema, residual tumor, and lymph node metastasis. Epithelial ovarian cancer patients were evaluated whether platelet count was decreased after surgery. Results: The mean platelet counts were (234.55±71.51)×109/L in the early stage epithelial ovarian cancer group, (308.12±111.95)×10<'9>/L in the advanced stage epithelial ovarian cancer group,and (206.28±52.62)×109/L in the benign ovarian tumor group, with a significant difference among the 3 groups (P<0.05).In the early stage epithelial ovarian cancer group, the platelet count was correlated with histopathology. In the advanced stage epithelial ovarian cancer group, there was a correlation between thrombocytosis and the incidence of that residual tumor diameter was greater than 2 cm. But there was no relationship between platelet count and histopathology, CA125, abdominal edema, or lymph node metastasis. In general the platelet count was decreased after surgery. Conclusion: An increased platelet count is commonly seen in patients with epithelial ovarian cancer, but it usually decreases after surgery. Patients with thrombocytosis have poor prognosis. Platelet count can be used as a marker for the development and prognosis of epithelial ovarian cancer.

Objective:The aim of the study was to investigate the clinical value and application of ATP based bioluminescence tumor chemosensitivity assay (ATP-TCA) in the chemotherapy for hydrothorax caused by non-small cell lung cancer (NSCLC). Methods:Hydrothorax specimens from 120 NSCLC patients were analyzed by ATP-TCA and the most sensitive chemotherapeutic drugs were used in NSCLC patients (treatment group). At the same time, 56 NSCLC patients with hydrothorax were admitted in our Hospital (Department of Oncology, The No. 2 People’s Hospital of Yibin, China) and given chemotherapy without guidance of the ATP-TCA (control group). Before the third chemotherapeutic cycle, clinical outcomes were analyzed in the two groups. Results:Effective rate of hydrothorax in treatment group was 67%, while 46% in control group (P < 0.05). In refractory hydrothorax patients, they were 69% and 40% (P < 0.05), respectively. In vitro results correlated well with clinical outcomes (P < 0.01). Conclusion:Effective rate of chemotherapy for hydrothorax in NSCLC is higher in treatment group than that in control group. ATP-TCA is especially helpful for refractory hydrothorax.     

Capecitabine maintenance therapy for XT chemotherapy-sensitive patients with metastatic triple-negative breast cancer

Objective： To investigate the efficacy and safety of capecitabine maintenance therapy（MT） after initial capecitabine plus docetaxel（XT） chemotherapy in patients with metastatic triple-negative breast cancer（m TNBC）.
Methods： Fifty-five m TNBC patients treated with XT chemotherapy between May 2007 and June 2013 were retrospectively analyzed. When initial disease control was achieved by the combination chemotherapy, capecitabine was continued for 32 patients（MT）, while 23 patients remained without any treatment（nonMT）. We compared progression-free survival（PFS） and safety of both groups.
Results： The median PFS of 55 patients was 8.1 months, overall median PFS time of 32 patients in the capecitabine MT group and 23 in the non-MT group was 10.1 vs. 6.7 months（P=0.032）, respectively. When compared PFS time of maintenance treatment, single-agent capecitabine prolonged PFS by 7.1 months, for non-MT patients, the PFS without any treatment was 3.1 months, and this between-group difference was statistically significant（P=0.003）. Adverse events, including of hematologic toxicity, gastrointestinal toxicities, hand-foot syndrome and abnormal liver function were not significantly different between two groups.
Conclusions： After initial disease control was achieved with the XT combination chemotherapy, capecitabine MT can significantly prolong PFS time with a favorable safety profile in m TNBC patients.

Clinical and Prognostic Features of Essential Thrombocythemia: Comparison of 2001 WHO Versus 2008/2016 WHO Criteria in a Large Single-center Cohort

BackgroundAccording to 2008/2016 classification of the World Health Organization (WHO), a platelet (PLT) count ≥ 450 × 10⁹/L, reduced from the previously published WHO 2001 indicated level ≥ 600 × 10⁹/L, was considered the new PLT threshold for the diagnosis of essential thrombocythemia (ET).Patients and MethodsTo validate this important diagnostic change in a setting of current clinical practice, we retrospectively analyzed clinical and hematologic features at diagnosis and during follow-up of 162 patients with ET, diagnosed in our center from January 2008 to December 2017. We subdivided patients according to PLT value at baseline into Group A (PLT ≥ 600 × 10⁹/L) (124 patients; 76.5%) and Group B (PLT ≥ 450 × 10⁹/L < 600 × 10⁹/L) (38 patients; 23.5%).ResultsAmong clinical features, only the median value of leukocytes (P < .001) was significantly higher in Group A. Cytostatic treatment was administered in 103 patients, with a significantly higher rate in patients of group A (P < .001). After a median follow-up of 42.4 months (interquartile range, 22.1-70.6 months), 8 thrombotic events were recorded in the entire cohort, without differences between the 2 groups (P = .336). The 5-year overall survival (OS) of the entire cohort was 96.9% (95% confidence interval, 92.6%-100%), without differences between the 2 groups (P = .255).ConclusionsOur data indicate a substantial homogeneity among patients with ET regardless of the PLT count at diagnosis, thus confirming the usefulness of the 2008/2016 WHO diagnostic criteria.     

Significance of thrombocytopenia in myelodysplastic syndromes: associations and prognostic implications

PurposeTo analyze the incidence and significance of thrombocytopenia in patients with myelodysplastic syndrome (MDS).Patients and MethodsA total of 2517 patients with MDS referred to our institution since 1993 were analyzed, with a specific focus on the incidence and associations of thrombocytopenia.ResultsThe median age of the study group was 66 years. The median survival was 13 months. Platelet counts <100 × 10⁹/L were noted in 65%, and platelets counts <30 × 10⁹/L in 26%. Each platelets count drop below the range of 200 × 10⁹/L has shown a larger magnitude change in terms of worsening effect on survival. Therefore, smaller ranges of platelet counts of <200 × 10⁹/L were studied. Platelet cutoffs of 30, 50, and 200 × 10⁹/L thus were identified to have significant associations with differences in survival. Significant thrombocytopenia was associated with poor performance, other cytopenias, adverse karyotype, and advanced MDS phases. Thrombocytopenia was associated with worse prognosis; it also was predicted for worse outcome within each of the International Prognostic Scoring System risk groups.ConclusionPrognosis in MDS is directly associated with the severity of thrombocytopenia.     

Timely Withdrawal of G-CSF Reduces the Occurrence of Thrombocytopenia During Dose-dense Chemotherapy

Summary Background. Post chemotherapy Granulocyte colony stimulating factor (G-CSF) reduces leucopenia, while G-CSF priming shortly before chemotherapy increases myelotoxicity. We performed a trial with a two-schedule crossover design to determine the optimal G-CSF schedule for densified 2-weekly chemotherapy Methods. During 2-weekly chemotherapy days 1 and 2, G-CSF was given on days 3–10, with a G-CSF-free interval before the next chemotherapy cycle of 5 days, or on days 3–13, with a G-CSF-free interval of 2 days. In schedule A, cycle II was preceded by a 5 days, cycle III and IV by a 2 days and cycle V by a 5 days G-CSF free interval. In schedule B, this was 2, 5, 5, and 2 days, respectively Results. Intra-patient comparison for cycles II versus III and cycles IV versus V showed that platelet (PLT) nadir count was significantly lower for cycles preceded by a 2-days compared to a 5-days G-CSF free interval: mean difference 45.7 × 10⁹/l (95% CI 33.2–58.2, p = 0.0001). Neutrophil count did not differ significantly (p = 0.85) Conclusion. Timely withdrawal of G-CSF in dose-dense chemotherapy reduces chemotherapy-related thrombocytopenia. Leucopenia was not aggravated, reflecting a protective effect of post-chemotherapy G-CSF
