A diagnosis of early stage HCC has proven to be very difficult because of its insidious feature in onset and development. At the time of diagnosis, most HCC cases are locally advanced and/or distant metastatic, which results in difficulty to be treated and poor prognosis. For advanced HCC, systemic therapy is frequently adopted as an important palliative method. In recent years, clinical studies and observations have often reported about systemic anti-cancer therapy of advanced HCC, including molecular target therapy, systemic chemotherapy and immunotherapy. In this article, we review these treatment modalities to provide a reference for clinicians.展开更多

Sorafenib is the choice therapy for advanced HCC. Over time several randomized phase Ⅲ trials have been performed testing sunitinib, brivanib, linifanib and other molecules in head-tohead comparison with Sorafenib as first-line treatment for advanced-stage HCC, but none of these has so far been registered in this setting. Moreover, another feared vacuum arises from the absence of molecules registered as second-line therapy for patients who have failed Sorafenib, representing an urgent unmet medical need. To date all molecules tested as second-line therapies for advanced hepatocellular carcinoma, failed to demonstrate an increased survival compared to placebo. What are the possible reasons for the failure? What we should expect in the near future?展开更多

For this study, departmental records in Breast Disease Center of Peking University First Hospital from January 2008 to December 2015 were retrospectively reviewed to identify cases of OBC. Eleven cases were included, and all patients were female, with a median age of 56 (range: 29-75) years. The sensitivity of magnetic resonance imaging (MRD was I00%, and the false positive rate was 33.3%. Based on histologic analysis of the axillary node, 9 (81.8%) cases were grade 3, and 2 (18.2%) cases were grade 2; 4 (36.4%) cases were 〉10% estrogen receptor (ER) positive and 6 (54.5%) human epidermal growth receptor 2 (HER2) positive. Nine cases (81.8%) exhibited over 30% Ki67 expression. PST was performed in 5 of the 11 cases. The lymph node response rate was 100% (5/5), but no complete remission was achieved. In conclusion, aggressive subtypes were predominant among the included cases, and PST should be considered for OBC treatment options.展开更多

In recent years, the combination of conventional aggressive curettage with targeted adjuvant anti-osteoclastic agents including bisphosphonates and denosumab have led to lower recurrence rates in patients with GCT in a small number of retrospective case series. Furthermore, efficacy of the same anti-osteoclastic agents has been shown in cases of unresectable GCT of bone, leading to decreased rates of tumor progression and stabilization of disease. This review assesses whether the current literature weakly, moderately, or strongly supports a targeted systemic treatment as the standard of care in patients with GCT. Methods: We conducted a current search of the MEDLINE database for literature pertaining to systemic GCT treatment. Our inclusion criteria were as follows: 1) studies that reported on a series of patients with resectable or unresectable cases of GCT;2) a subset of patients must have been treated with systemic bisphosphonate or RANK-L inhibitor therapy;3) each series had a minimum of 10 patients with histopathologically confirmed GCT;4) each series stated their follow-up period. Results: Overall 6 studies, reporting on a total of 487 patients, were selected for inclusion in this review. For analysis, these 6 retrospective studies were subdivided into series where all GCT patients had resectable tumors (n = 4) and series where patients had a mix of resectable and unresectable tumors (n = 2). The overall recurrence rate of GCT in patients with resectable tumors treated with adjuvant systemic bisphosphonates was 6.7% compared to 48.4% in patients not treated with adjuvant systemic bisphosphonates (p 0.0001). In patients with both resectable and unresectable primary aggressive, recurrent, or metastatic GCT disease, systemic bisphosphonate and denosumab demonstrated good efficacy with decreased rates of disease progression and recurrence. In general the side effects of bisphosphonates were mild while denosumab had a more severe side effect profile. Conclusions: Systemic treatment with bisphosphonates or denosumab in cases of GCT is promising, but there is a lack of high-level evidence with sufficient follow-up supporting their use. We believe the current literature provides moderate support to recommend a short course of adjuvant peri-operative systemic bisphosphonate treatment for patients with resectable primary GCT and moderate support to recommend adjuvant peri-operative (resectable) and non-operative (unresectable) use of denosumab in cases of primary aggressive, recurrent, or metastatic GCT. With either systemic treatment, patients should be well counseled on all potential side effects in addition to alternative treatment, which includes the option of no systemic treatment.展开更多

The goal of this study was to understand treatment patterns, biomarker testing practices, treatment adherence, and the clinical and economic outcomes associated with chemotherapy for metastatic disease. Methods and Materials: We retrospectively examined electronic health records of patients with metastatic CRC who initiated chemotherapy between 01 January 2007 and 30 June 2011, with follow-up to 30 June 2012. Parameters analyzed included demographics and clinical characteristics, treatment patterns, clinical outcomes, and health care resource utilization. Results: In the analysis, 756 patients were included;median age was 61 years (55% male) at start of first line therapy. The most commonly used regimens in the first, second, and third line were FOLFOX + bevacizumab (46%), FOLFIRI + bevacizumab (23%), and irinotecan + cetuximab (23%) respectively. Adherence to guidelines decreased with increasing line of therapy. When assessed by treatment backbone categories in the third line, outcome measures including overall survival (OS), and time to treatment discontinuation (TTD) were not statistically different between groups. In the multivariable model, body mass index (BMI), performance status, and KRAS were significant predictors of survival. Conclusions: This study provides insight into patterns of care and outcomes of mCRC patients for the aforementioned time period. As treatment options for mCRC evolve, it is valuable to understand the continuum of care to help inform future treatment among candidates for continued therapy.展开更多

The early identification of metastatic disease represents a major prognostic factor for GEP-NENs patients. Radical surgical resection, which is feasible for a minority of patients, is considered the only curative option, while the best management for patients with unresectable liver metastases is still being debated. In the last few years, a number of locoregional and systemic treatments has become available for GEP-NEN patients metastatic to the liver. However, to date only a few prospective studies have compared those therapies and the optimal management option is based on clinical judgement. Additionally, locoregional treatments appear feasible and safe for disease control for patients with limited liver involvement and effective in symptoms control for patients with diffuse liver metastases. Considering the lack of randomized controlled trials comparing the locoregional treatments of liver metastatic NEN patients, clinical judgment remains key to set the most appropriate therapeutic pathway. Prospective data may ultimately lead to more personalized and optimized treatments. The present review analyzes all the locoregional therapy modalities(i.e., surgery, ablative treatments and transarterial approach) and aims to provide clinicians with a useful algorithm to best treat GEP-NEN patients metastatic to the liver.展开更多
文摘Hepatocellular carcinoma(HCC)is a high mortality neoplasm which usually appears on a cirrhotic liver.The therapeutic arsenal and subsequent prognostic outlook are intrinsically linked to the HCC stage at diagnosis.Notwithstanding the current deployment of treatments with curative intent(liver resection/local ablation and liver transplantation)in early and intermediate stages,a high rate of HCC recurrence persists,underscoring a pivotal clinical challenge.Emergent systemic therapies(ST),particularly immunotherapy,have demonstrate promising outcomes in terms of increase overall survival,but they are currently bound to the advanced stage of HCC.This review provides a comprehensive analysis of the literature,encompassing studies up to March 10,2024,evaluating the impact of novel ST in the early and intermediate HCC stages,specially focusing on the findings of neoadjuvant and adjuvant regimens,aimed at increasing significantly overall survival and recurrence-free survival after a treatment with curative intent.We also investigate the potential role of ST in enhancing the downstaging rate for the intermediate-stage HCC initially deemed ineligible for treatment with curative intent.Finally,we critically discuss about the current relevance of the results of these studies and the encouraging future implications of ST in the treatment schedules of early and intermediate HCC stages.

文摘Gastrointestinal stromal tumors(GISTs)are the most common type of soft tissue sarcoma in the gastrointestinal tract.Most GISTs have been attributed to activated gain-of-function mutations in either KIT or platelet-derived growth factor receptorα,making these molecular features essential targets for therapeutic interventions.Although surgery is the standard treatment for localized GISTs,patients often experience relapse and disease progression even after surgery.In recent years,targeted therapy has significantly improved the prognosis of patients with advanced GISTs.Imatinib mesylate,a KIT inhibitor,is the first-line treatment for advanced GISTs and has revolutionized the treatment of this disease.However,drug resistance remains a major issue with imatinib treatment,as a significant majority of patients become resistant to imatinib either after initiation or after 2–3 years of treatment.Consequently,novel tyrosine kinase inhibitors such as sunitinib,regorafenib,ripretinib,and avapritinib have been introduced to address drug resistance.Immunotherapy has emerged as a potential approach for the treatment of advanced GISTs.This review comprehensively summarizes the pathogenesis of GISTs and the development of targeted therapies and immunotherapies,provides an overview of the emergence of drug resistance in advanced GISTs,and discusses the challenges and prospects associated with the treatment of GISTs.

文摘Improvements in early screening,new diagnostic techniques,and surgical treatment have led to continuous downward trends in hepatocellular carcinoma(HCC)morbidity and mortality rates.However,high recurrence and refractory cancer after hepatectomy remain important factors affecting the long-term prognosis of HCC.The clinical characteristics and prognosis of recurrent HCC are heterogeneous,and guidelines on treatment strategies for recurrent HCC are lacking.Therapies such as surgical resection,radiofrequency ablation,and transhepatic arterial chemoembolization are effective for tumors confined to the liver,and targeted therapy is a very important treatment for unresectable recurrent HCC with systemic metastasis.With the deepening of the understanding of the immune microenvironment of HCC,blocking immune checkpoints to enhance the antitumor immune response has become a new direction for the treatment of HCC.In addition,improvements in the tumor immune microenvironment caused by local treatment may provide an opportunity to improve the therapeutic effect of HCC treatment.Ongoing and future clinical trial data of combined therapy may develop the new treatment scheme for recurrent HCC.This paper reviews the pattern of recurrent HCC and the characteristics of the immune microenvironment,demonstrates the basis for combining local treatment and systemic treatment,and reports current evidence to better understand current progress and future approaches in the treatment of recurrent HCC.
文摘Significant progress has been achieved in the treatment of metastatic colorectal cancer(mCRC)patients during the last 20 years.There are currently numerous treatments available for the first-line treatment of mCRC.Sophisticated molecular technologies have been developed to reveal novel prognostic and predictive biomarkers for CRC.The development of next-generation sequencing and wholeexome sequencing,which are strong new tools for the discovery of predictive molecular biomarkers to facilitate the delivery of customized treatment,has resulted in tremendous breakthroughs in DNA sequencing technology in recent years.The appropriate adjuvant treatments for mCRC patients are determined by the tumor stage,presence of high-risk pathologic characteristics,microsatellite instability status,patient age,and performance status.Chemotherapy,targeted therapy,and immunotherapy are the main systemic treatments for patients with mCRC.Despite the fact that these novel treatment choices have increased overall survival for mCRC,survival remains optimal for individuals with non-metastatic disease.The molecular technologies currently being used to support our ability to practice personalized medicine;the practical aspects of applying molecular biomarkers to regular clinical practice;and the evolution of chemotherapy,targeted therapy,and immunotherapy strategies for the treatment of mCRC in the front-line setting are all reviewed here.
文摘Gene therapy has shown great potential to treat various diseases by repairing the abnormal gene function.However,a great challenge in bringing the nucleic acid formulations to the market is the safe and effective delivery to the specific tissues and cells.To be excited,the development of ionizable drug delivery systems(IDDSs)has promoted a great breakthrough as evidenced by the approval of the BNT162b2 vaccine for prevention of coronavirus disease 2019(COVID-19)in 2021.Compared with conventional cationic gene vectors,IDDSs can decrease the toxicity of carriers to cell membranes,and increase cellular uptake and endosomal escape of nucleic acids by their unique pH-responsive structures.Despite the progress,there remain necessary requirements for designing more efficient IDDSs for precise gene therapy.Herein,we systematically classify the IDDSs and summarize the characteristics and advantages of IDDSs in order to explore the underlying design mechanisms.The delivery mechanisms and therapeutic applications of IDDSs are comprehensively reviewed for the delivery of plasmid DNA(pDNA)and four kinds of RNA.In particular,organ selecting considerations and high-throughput screening are highlighted to explore efficiently multifunctional ionizable nanomaterials with superior gene delivery capacity.We anticipate providing references for researchers to rationally design more efficient and accurate targeted gene delivery systems in the future,and indicate ideas for developing next generation gene vectors.
文摘Pancreatic cancer is a deadly disease with an extremely poor 5-year survival rate due to treatment resistance and late-stage detection.Despite numerous years of research and pharmaceutical development,these figures have not changed.Treatment options for advanced pancreatic cancer are still limited.This illness is typically detected at a late stage,making curative surgical resection impossible.Chemotherapy is the most commonly utilized technique for treating advanced pancreatic cancer but has poor efficacy.Targeted therapy and immunotherapy have made significant progress in many other cancer types and have been proven to have extremely promising possibilities;these therapies also hold promise for pancreatic cancer.There is an urgent need for research into targeted treatment,immunotherapy,and cancer vaccines.In this review,we emphasize the founda-tional findings that have fueled the therapeutic strategy for advanced pancreatic cancer.We also address current advancements in targeted therapy,immuno-therapy,and cancer vaccines,all of which continue to improve the clinical outcome of advanced pancreatic cancer.We believe that clinical translation of these novel treatments will improve the low survival rate of this deadly disease.

文摘Immunotherapy has become a promising research“hotspot”in cancer treatment.“Soldier”immune cells are not uniform throughout the body;they accumulate mostly in the immune organs such as the spleen and lymph nodes(LNs),etc.The unique structure of LNs provides the microenvironment suitable for the survival,activation,and proliferation of multiple types of immune cells.LNs play an important role in both the initiation of adaptive immunity and the generation of durable anti-tumor responses.Antigens taken up by antigen-presenting cells in peripheral tissues need to migrate with lymphatic fluid to LNs to activate the lymphocytes therein.Meanwhile,the accumulation and retaining of many immune functional compounds in LNs enhance their efficacy significantly.Therefore,LNs have become a key target for tumor immunotherapy.Unfortunately,the nonspecific distribution of the immune drugs in vivo greatly limits the activation and proliferation of immune cells,which leads to unsatisfactory anti-tumor effects.The efficient nano-delivery system to LNs is an effective strategy to maximize the efficacy of immune drugs.Nano-delivery systems have shown beneficial in improving biodistribution and enhancing accumulation in lymphoid tissues,exhibiting powerful and promising prospects for achieving effective delivery to LNs.Herein,the physiological structure and the delivery barriers of LNs were summarized and the factors affecting LNs accumulation were discussed thoroughly.Moreover,developments in nano-delivery systems were reviewed and the transformation prospects of LNs targeting nanocarriers were summarized and discussed.
文摘BACKGROUND Perihilar cholangiocarcinoma(pCCA)is a highly malignant tumor arising from the biliary tree.Radical surgery is the only treatment offering a chance of long-term survival.However,limited by the tumor’s anatomic location and peri-vascular invasion,most patients lose the chance for curative treatment.Therefore,more methods to increase the resectability of tumors as well as to improve outcomes are needed.CASE SUMMARY A 68-year-old female patient had a hepatic hilar mass without obvious symptoms.Laboratory results showed hepatitis B positivity.Magnetic resonance imaging indicated that the mass(maximum diameter:41 mm)invaded the left and right branches of the main portal vein,as well as the middle,left and right hepatic veins;enlarged lymph nodes were also detected in the hilum.The patient was diagnosed with pCCA,and the clinical stage was determined to be T4N1M0(stage IIIC).Considering the tumor’s anatomic location and vascular invasion,systematic conversion therapy followed by ex vivo liver resection and autotrans-plantation(ELRA)was determined as personalized treatment for this patient.Our original systemic sequential therapeutic strategy(lenvatinib and tislelizumab in combination with gemcitabine and cisplatin)was successfully adopted as conversion therapy because she achieved partial response after three cycles of treatment,without severe toxicity.ELRA,anastomotic reconstruction of the middle hepatic vein,right hepatic vein,root of portal vein,inferior vena cava and right hepatic artery,and lymph node dissection were performed at one month after systemic therapy.Pathological and immunohistochemical examination confirmed the diagnosis of pCCA with lymph node metastasis.Although the middle hepatic vein was partially obstructed four months later,hepatic vein stent implantation successfully addressed this problem.The patient has survived for 22 mo after the diagnosis,with no evidence of recurrence or metastasis.CONCLUSION An effective therapeutic strategy for conversion therapy greatly increases the feasibility and efficiency of ELRA.
文摘Primary liver cancer, mainly consisting of hepatocellular carcinoma(HCC), is one of common malignancies worldwide, and prevalent among the Chinese population. A diagnosis of early stage HCC has proven to be very difficult because of its insidious feature in onset and development. At the time of diagnosis, most HCC cases are locally advanced and/or distant metastatic, which results in difficulty to be treated and poor prognosis. For advanced HCC, systemic therapy is frequently adopted as an important palliative method. In recent years, clinical studies and observations have often reported about systemic anti-cancer therapy of advanced HCC, including molecular target therapy, systemic chemotherapy and immunotherapy. In this article, we review these treatment modalities to provide a reference for clinicians.
文摘Hepatocellular carcinoma(HCC) is the main cause of death in patients with cirrhosis, with an increasing incidence worldwide. Sorafenib is the choice therapy for advanced HCC. Over time several randomized phase Ⅲ trials have been performed testing sunitinib, brivanib, linifanib and other molecules in head-tohead comparison with Sorafenib as first-line treatment for advanced-stage HCC, but none of these has so far been registered in this setting. Moreover, another feared vacuum arises from the absence of molecules registered as second-line therapy for patients who have failed Sorafenib, representing an urgent unmet medical need. To date all molecules tested as second-line therapies for advanced hepatocellular carcinoma, failed to demonstrate an increased survival compared to placebo. What are the possible reasons for the failure? What we should expect in the near future?
文摘BACKGROUND The majority of clinical trials of first-line systemic treatments for hepatocellular carcinoma(HCC)used placebo or sorafenib as comparators,and there are limited data providing a cross comparison of treatments in this setting,especially for newly-approved immune checkpoint inhibitor and vascular endothelial growth factor inhibitor combination treatments.AIM To systematically review and compare response rates,survival outcomes,and safety of first-line systemic therapies for advanced hepatocellular carcinoma.METHODS We searched PubMed,Science Direct,the Cochrane Database,Excerpta Medica Database,and abstracts from the American Society of Clinical Oncology 2020 annual congress.Eligible studies were randomized controlled trials of systemic therapy enrolling adults with advanced/unresectable HCC.Risk of bias was assessed with the Cochrane risk of bias tool for randomized controlled trials.A network meta-analysis was used to synthesize data and perform direct and indirect comparisons between treatments.P value,a frequentist analog to the surface under the cumulative ranking curve,was used to rank treatments.RESULTS In total,1398 articles were screened and 27 included.Treatments compared were atezolizumab plus bevacizumab,brivanib,donafenib,dovitinib,FOLFOX4,lenvatinib,linifanib,nintedanib,nivolumab,sorafenib,sunitinib,vandetanib,11 sorafenib combination therapies,and three other combination therapies.For overall response rate,lenvatinib ranked 1/19,followed by atezolizumab plus bevacizumab and nivolumab.For progression-free survival(PFS),atezolizumab+bevacizumab was ranked 1/15,followed by lenvatinib.With the exception of atezolizumab+bevacizumab[hazard ratios(HR)PFS=0.90;95%confidence interval(CI):0.64-1.25],the estimated HRs for PFS for all included treatments vs lenvatinib were>1;however,the associated 95%CI passed through unity for bevacizumab plus erlotinib,linifanib,and FOLFOX4.For overall survival,atezolizumab plus bevacizumab was ranked 1/25,followed by vandetanib 100 mg/d and donafinib,with lenvatinib ranked 6/25.Atezolizumab+bevacizumab was associated with a lower risk of death vs lenvatinib(HRos=0.63;95%CI:0.44-0.89),while the HR for overall survival for most other treatments vs lenvatinib had associated 95%CIs that passed through unity.Vandetanib 300 mg/d and 100 mg/d were ranked 1/13 and 2/13,respectively,for the lowest incidence of treatment terminations due to adverse events,followed by sorafenib(5/13),lenvatinib(10/13),and atezolizumab+bevacizumab(13/13).CONCLUSION There is not one single first-line treatment for advanced HCC associated with superior outcomes across all outcome measurements.Therefore,first-line systemic treatment should be selected based on individualized treatment goals.

文摘There is a lack of investigation into the biological characteristics and preoperative systemic therapy (PST) for occult breast cancer (OBC). For this study, departmental records in Breast Disease Center of Peking University First Hospital from January 2008 to December 2015 were retrospectively reviewed to identify cases of OBC. Eleven cases were included, and all patients were female, with a median age of 56 (range: 29-75) years. The sensitivity of magnetic resonance imaging (MRD was I00%, and the false positive rate was 33.3%. Based on histologic analysis of the axillary node, 9 (81.8%) cases were grade 3, and 2 (18.2%) cases were grade 2; 4 (36.4%) cases were 〉10% estrogen receptor (ER) positive and 6 (54.5%) human epidermal growth receptor 2 (HER2) positive. Nine cases (81.8%) exhibited over 30% Ki67 expression. PST was performed in 5 of the 11 cases. The lymph node response rate was 100% (5/5), but no complete remission was achieved. In conclusion, aggressive subtypes were predominant among the included cases, and PST should be considered for OBC treatment options.
文摘Background: Giant cell tumor (GCT) is a common benign tumor of the appendicular and axial skeleton that represents 5% of all primary bone tumors. In recent years, the combination of conventional aggressive curettage with targeted adjuvant anti-osteoclastic agents including bisphosphonates and denosumab have led to lower recurrence rates in patients with GCT in a small number of retrospective case series. Furthermore, efficacy of the same anti-osteoclastic agents has been shown in cases of unresectable GCT of bone, leading to decreased rates of tumor progression and stabilization of disease. This review assesses whether the current literature weakly, moderately, or strongly supports a targeted systemic treatment as the standard of care in patients with GCT. Methods: We conducted a current search of the MEDLINE database for literature pertaining to systemic GCT treatment. Our inclusion criteria were as follows: 1) studies that reported on a series of patients with resectable or unresectable cases of GCT;2) a subset of patients must have been treated with systemic bisphosphonate or RANK-L inhibitor therapy;3) each series had a minimum of 10 patients with histopathologically confirmed GCT;4) each series stated their follow-up period. Results: Overall 6 studies, reporting on a total of 487 patients, were selected for inclusion in this review. For analysis, these 6 retrospective studies were subdivided into series where all GCT patients had resectable tumors (n = 4) and series where patients had a mix of resectable and unresectable tumors (n = 2). The overall recurrence rate of GCT in patients with resectable tumors treated with adjuvant systemic bisphosphonates was 6.7% compared to 48.4% in patients not treated with adjuvant systemic bisphosphonates (p 0.0001). In patients with both resectable and unresectable primary aggressive, recurrent, or metastatic GCT disease, systemic bisphosphonate and denosumab demonstrated good efficacy with decreased rates of disease progression and recurrence. In general the side effects of bisphosphonates were mild while denosumab had a more severe side effect profile. Conclusions: Systemic treatment with bisphosphonates or denosumab in cases of GCT is promising, but there is a lack of high-level evidence with sufficient follow-up supporting their use. We believe the current literature provides moderate support to recommend a short course of adjuvant peri-operative systemic bisphosphonate treatment for patients with resectable primary GCT and moderate support to recommend adjuvant peri-operative (resectable) and non-operative (unresectable) use of denosumab in cases of primary aggressive, recurrent, or metastatic GCT. With either systemic treatment, patients should be well counseled on all potential side effects in addition to alternative treatment, which includes the option of no systemic treatment.

文摘BACKGROUND Undifferentiated embryonal sarcoma of the liver(UESL)is a rare and aggressive mesenchymal tumor in children.Herein,we describe our experience in neoadjuvant therapy(NAT)and subsequent surgery for the treatment of UESL in children.AIM To evaluate the efficacy of NAT and explore a new choice for successful operation of UESL in children.METHODS We retrospectively analyzed six patients newly diagnosed with unresectable UESL who received NAT and then surgery at our center between January 2004 and December 2019.The tumor was considered unresectable if it involved a large part of both lobes of the liver or had invaded the main hepatic vessels or inferior vena cava.The NAT included preoperative transcatheter arterial chemoembol ization(TACE)and systemic chemotherapy.The patients were 4 boys and 2 girls with a mean age of 7 years.The longest tumor at presentation ranged from 8.6 to 14.8 cm(mean,12 cm).Extrahepatic metastases were present in 2 cases.Preoperative systemic chemotherapy was administered 3 wk after TACE.Tumor resection was performed 3 wk after one or two cycles of NAT.The patients received systemic chemotherapy after surgery.RESULTS All patients successfully underwent NAT and complete resection.The tumor volumes decreased by 18.2%–68.7%,with a mean decrease of 36%after 1 cycle of NAT(t=3.524,P=0.017).According to the Response Evaluation Criteria In Solid Tumors criteria,4 patients had a partial response and underwent surgery,while 2 had stable disease and received another cycle of NAT before surgery.Massive tumor necrosis was seen on pathological examination of the surgical specimen:>90%necrosis in two,>50%necrosis in three,and 25%necrosis in 1,with an average of 71.8%.Post-NAT complications included fever,nausea and vomiting,and mild bone marrow suppression.Elevated alanine transaminase levels occurred in all patients,which returned to normal within 7–10 d after treatment.No cardiac or renal toxicity,severe hepatic dysfunction,bleeding and nontarget embolization were observed in the patients.The median follow-up period was 8 years with an overall survival of 100%.CONCLUSION NAT effectively reduced tumor volume,cleared the tumor margin,and caused massive tumor necrosis.This may be a promising choice for successful surgery of UESL in children.
文摘A number of very interesting studies presented this year at the ASCO (American Society of Clinical Oncology) Annual Meeting, the ASCO-GU (ASCO Genitourinary Cancers) Spring Meeting, and the ESMO (European Society for Medical Oncology) Annual Congress could strongly influence or even revolutionize the systemic treatment of advanced renal cell carcinoma (RCC). The aim of this article is to identify, summarize and discuss some outstanding studies of direct or indirect clinical relevance for systemic therapy.
文摘Objective: To research the effectiveness of ulinastatin in combination with continuous renal replacement therapy in treating sepsis acute kidney injury and its effect on systemic inflammation, immune function and miRAN expression. Methods: The 84 patients who were diagnosed with sepsis complicated by acute kidney injury in our hospital between May 2020 and June 2022 were chosen and randomly assigned to the study group (n = 42) and the control group (n = 42). Ulinastatin in combination with continuous renal replacement therapy was administered to the study group, whereas the control group was administered with continuous renal replacement therapy alone. Both groups’ clinical effects were observed. The levels of blood urea nitrogen (BUN), serum creatinine (SCr), tumor necrosis factor-α (TNF-α), high sensitivity Creactive protein (hs-CRP), vascular cell adhesion molecule-1 (VCAM-1), IgG, IgA, IgM, expression levels of miR-233 and miR-10a were compared among both the groups, pre-, and post-treatment. Results: The study group’s overall effectiveness rate was higher that is 95.24%, in comparison to the control group’s 78.57%, and this difference was statistically significant (P α, hs-CRP, VCAM-1, and miR-233 and miR-10a expression levels in both the study and control groups were decreased, however, the study group had reduced levels in comparison to the control group, with statistically significant differences (P P Conclusion: Ulinastatin in combination with continuous renal replacement therapy for treating sepsis acute kidney injury exhibits a positive effect and can significantly improve the systemic inflammation and immune function in patients.
文摘Introduction: Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the third leading cause of cancer deaths in the United States. The goal of this study was to understand treatment patterns, biomarker testing practices, treatment adherence, and the clinical and economic outcomes associated with chemotherapy for metastatic disease. Methods and Materials: We retrospectively examined electronic health records of patients with metastatic CRC who initiated chemotherapy between 01 January 2007 and 30 June 2011, with follow-up to 30 June 2012. Parameters analyzed included demographics and clinical characteristics, treatment patterns, clinical outcomes, and health care resource utilization. Results: In the analysis, 756 patients were included;median age was 61 years (55% male) at start of first line therapy. The most commonly used regimens in the first, second, and third line were FOLFOX + bevacizumab (46%), FOLFIRI + bevacizumab (23%), and irinotecan + cetuximab (23%) respectively. Adherence to guidelines decreased with increasing line of therapy. When assessed by treatment backbone categories in the third line, outcome measures including overall survival (OS), and time to treatment discontinuation (TTD) were not statistically different between groups. In the multivariable model, body mass index (BMI), performance status, and KRAS were significant predictors of survival. Conclusions: This study provides insight into patterns of care and outcomes of mCRC patients for the aforementioned time period. As treatment options for mCRC evolve, it is valuable to understand the continuum of care to help inform future treatment among candidates for continued therapy.
文摘Gastroenteropancreatic neuroendocrine neoplasms(GEP-NENs) frequently present with distant metastases at the time of diagnosis and the liver is the most frequent site of spreading. The early identification of metastatic disease represents a major prognostic factor for GEP-NENs patients. Radical surgical resection, which is feasible for a minority of patients, is considered the only curative option, while the best management for patients with unresectable liver metastases is still being debated. In the last few years, a number of locoregional and systemic treatments has become available for GEP-NEN patients metastatic to the liver. However, to date only a few prospective studies have compared those therapies and the optimal management option is based on clinical judgement. Additionally, locoregional treatments appear feasible and safe for disease control for patients with limited liver involvement and effective in symptoms control for patients with diffuse liver metastases. Considering the lack of randomized controlled trials comparing the locoregional treatments of liver metastatic NEN patients, clinical judgment remains key to set the most appropriate therapeutic pathway. Prospective data may ultimately lead to more personalized and optimized treatments. The present review analyzes all the locoregional therapy modalities(i.e., surgery, ablative treatments and transarterial approach) and aims to provide clinicians with a useful algorithm to best treat GEP-NEN patients metastatic to the liver.
