Filter by:Introduction: Gastrointestinal Stromal Tumors (GISTs) located in the jejunum or ileum (JI-GIST) are considered of worse prognosis compared to other locations. It has been suggested that this dogma should be revised. The aim of this study is to describe the characteristics of jejunoileal GISTs and its prognosis; and to compare them with gastric GISTs in the era of imatinib. Patients and methods: We retrospectively reviewed the clinical histories of all the patients diagnosed with GISTs between January 2000 and November 2016. Clinical and pathological data, as well recurrence, metastatic, disease-free survival (DFS) as overall (OS) rates of patients with JI-GIST or gastric GIST (G-GIST) were collected and compared.
To validate the tumor response rate: in the previous study, the investigators showed that TILA-TACE achieved 100% tumor response rate. However, as the study sample size was 40, the investigators need to validate the tumor response rate using a larger sample size; To validate the overall survival: in the previous study, the investigators showed that TILA-TACE significantly prolonged the overall survival of the patients with large and massive tumor. Again, the sample size was small, the investigators need to validate the data using a large sample size.
Although there seems to be no benefit from improving the histologic response rate or long-term survival of intra-arterial infusion of cisplatin for localized osteosarcoma of extremities with IOR/OS-3, IOR/OS-5, and COSS 86 protocols, such a treatment strategy is still believed to potentially increase the tumoricidal effect with an increase in higher local concentrations of the infused agents combined with longer tissue exposure time. Besides, the relationship of chemotherapy-induced necrosis and surgical margins is still the main concern for localized osteosarcoma patients to achieve long-term survival. The investigators intend to analyze the gain and loss from transcatheter intra-arterial limb infusion of cisplatin for extremity osteosarcoma in the past six years.
The investigators design a large sample size study in the real-world to explore whether targeted therapy and immunotherapy can improve the survival, quality of life and drug safety of patients with advanced hepatobiliary tumors, and analyze the correlation between genetic variation and the effectiveness of therapy.
To identify the efficiency of Irinotecan, Oxaliplatin, and S1 in patients with previously untreated local regional or metastatic pancreatic cancer.
Prostate cancer (PCa) is the second most frequently diagnosed cancer in men worldwide, accounting for 15% of all male cancers. In 2015, there were 220,800 estimated new cases of prostate cancer and 27,540 deaths by PCa, making this disease the second leading cause of cancer-related death for North American men. Men with PCa may develop lower urinary tract symptoms (LUTS) when prostate tumors invade or compress the prostatic urethra, the bladder or the neurovascular bundles, or when the prostate is enlarged. It has been estimated that over 40% of men with PCa experience moderate or severe LUTS. LUTS can impact profoundly on a man's quality of life (QoL); an effect that increases with increasing LUTS severity. Transurethral resection of prostate (TURP) can offer immediate relief of the obstruction in patients with benign prostatic hyperplasia (BPH). In contrast, palliative TURP (p-TURP) (the so-called "channel" TURP), is transurethral resection of prostate tissue in a patient with metastatic or locally advanced and/or previously treated PCa to alleviate obstructive voiding symptoms. Al¬though TURP is commonly performed to relieve bladder outlet ob¬struction (BOO) symptoms in patients with BPH, little known about the outcome of palliative transurethral plasma kinetic resection of prostate (p-TUPKRP) in patients with ad-vanced PCa. Gonadotropin-releasing hormone (GnRH) agonists as androgen deprivation therapy (ADT) are the standard treatment for many patients with PCa, particularly those with advanced or metastatic disease. The impact of ADT on tumor control and achieving the reduction in prostate specific antigen (PSA) is well established. But there is less information available on the effects on LUTSs in men with PCa. Some short-term studies of ADT with the GnRH antagonist or with ADT in the neoadjuvant setting have demonstrated reductions in LUTSs, measured by the International Prostate Symptom Score (IPSS). There are few published data on the longer-term effects of ADT on LUTSs, apart from an earlier interim analysis of data from the current study. In this study, p-TUPKRP combined with ADT will perform for 50 patients with advanced PCa complicated with severe LUTS. As a control, other 50 advanced PCa patients with same symptoms will be treated with ADT only. Some clinical data, including PSA, IPSS, QoL, Urinary flow rate (UFR), ECOG Score, Overall survival (OS), progression-free survival (PFS), will be analyzed. It is expected to explore the efficacy and safety of the combination therapy to advanced PCa with severe LUTS.
ICAN was a non-interventional study to explore the EGFR gene mutation status, clinical outcome and recurrent risk factors in early stage Chinese NSCLC with adenocarcinoma histology after complete resection (NIS-OCN-DUM-2009/1). The study had enrolled 571 patients from Apr. 2010 to Dec. 2010 in 24 sites located in the mainland of China. The study had completed and major results showed that EGFR mutation rate was 55.1% and 3-year DFS rate was 61.7% in early stage Chinese NSCLC with adenocarcinoma histology after complete resection. Postoperative pathologic stage, gender, surgical and resection types had a statistically significant association with 3-year DFS. This study is ICAN extension study with the purpose to collect the overall survival data from previous ICAN study. Approximately 571 patients who participated in ICAN study will be enrolled.
Prospective study of Predictive Factors of Survival With and Without Repetition With 5 and 10 Years Curative Post-oesophagectomy for Cancer of the Oesophagus
To standardize the surgery for advanced right hemi colon cancer with laparoscopy and investigate whether dorsal and medial hybrid approach could improve disease-free survival in patients with right colon cancer, compared with traditional medial-to-lateral approach in laparoscopic righ hemicolectomy.
After standard multimodal therapy, the prognosis of relapsed and unresectable high-grade osteosarcoma is dismal and unchanged over the last decades. We have already finished a prospective trial about apatinib for advanced osteosarcoma(NCT02711007) and find it has a objective response rate of aproximately 45% with median progression-free survival around 5 months. Thus, the investigators explored apatinib activity together with anti-PD1 therapy in order to induce durable response in patients with relapsed and unresectable osteosarcoma after the failure of first-line or second-line chemotherapy. Apatinib is a small-molecule vascular endothelial growth factors receptor (VEGFR) tyrosine kinase inhibitor, similar to pazopanib, but with a binding affinity 10 times to VEGFR-2 comparing with pazopanib or sorafenib. SHR-1210 is a humanized anti-PD-1 monoclonal antibody.
