BackgroundAt present, regorafenib and fruquintinib are the standard regimens for refractory metastatic colorectal cancer patients in China, but both options have limited efficacy. The aim of this study was to investigate the efficacy and safety of low-dose apatinib plus S-1 compared with regorafenib and fruquintinib in patients with metastatic colorectal cancer (mCRC) refractory to standard therapies.MethodsThe records of 114 patients with refractory mCRC in our center from April 2016 to September 2020 were retrospectively reviewed. Among these patients, 43 received apatinib 250 mg/day combined with S-1, 36 received regorafenib starting at 80 mg/day with weekly escalation, and 35 received fruquintinib 5 mg/day orally. Patients received radiographic examination every 1.5–2 months during the treatment period, progression-free survival time and overall survival time were analyzed and recorded.ResultsThe baseline clinical characteristics of the patients were broadly similar among the three groups. The median progression-free survival (mPFS) was 3.9 months [95% confidence interval (CI): 2.5–5.3] in the apatinib plus S-1 group, 3.1 months (95% CI: 1.9–4.2) in the fruquintinib group, and 2.4 months (95% CI: 2.1–2.7) in the regorafenib group, the mPFS of apatinib plus S-1 was significantly longer than that of regorafenib (HR =0.49, P=0.003) and fruquintinib (HR =0.60, P=0.048). The median overall survival (OS) was 8.2 months (95% CI: 5.4–11.0) in the apatinib plus S-1 group, 7.8 months (95% CI: 5.3–10.3) in the fruquintinib group, and 7.5 months (95% CI: 4.2–10.7) in the regorafenib group, which was comparable among the 3 groups. There was no statistical difference in disease control rate (DCR) among the three groups. Patients in the apatinib plus S-1 group had a higher incidence of hematological toxicity including anemia (62.8%), neutropenia (30.2%), and thrombocytopenia (39.5%), and the hand-foot skin reaction (58.3%) was more prevalent in the regorafenib group, while the adverse reaction of hypertension (45.7%) in the fruquintinib group was very significant.ConclusionsLow-dose apatinib plus S-1 prolonged PFS compared with regorafenib and fruquintinib, and is a potential alternative regimen for the treatment of refractory mCRC with tolerable and controlled toxicity. 相似文献

AIM and METHODS: We reviewed the oncological outcome in 40 consecutive patients with an osteosarcoma of the pelvic region, registered in the files of the Netherlands Committee on Bone Tumours (NCBT) between 1978 and 1995. RESULTS: Six patients had distant metastases at initial presentation (Enneking stage IIIB), 33 patients had stage IIB osteosarcoma and one patient stage IB osteosarcoma. Patients with metastases were treated with chemotherapy (four) or palliative procedures (two). Patients with non-metastatic osteosarcoma were treated with surgical procedures with (14) or without (four) neoadjuvant chemotherapy, chemotherapy without surgical resection (nine), or palliative procedures (seven). The median survival of stage IIB and IIIB osteosarcoma was 14 months (2-175) and 7.5 months (2-16), respectively. Survival in patients with stage IIB osteosarcoma treated with curative procedures was significantly better (P<0.0006) compared with stage IIB patients treated with palliative intent. Two and 5-year survival for patients with curatively treated stage IIB osteosarcoma was 35% and 26%, respectively; distant metastases had developed in 65% of these patients. On univariate analysis, positive prognostic factors for patients with stage IIB osteosarcoma were complaints of 3 months or less before initial presentation, tumour size of 8 cm or less, osteoblastic subtype, surgical resection of the primary tumour and limb salvage procedures. CONCLUSION: In conclusion, the prognosis of pelvic osteosarcoma remained poor despite modern multimodality treatment regimens, including neoadjuvant chemotherapy. 相似文献

Patients with metastatic, progressive, or recurrent bone tumors have a dismal outcome. Sorafenib has been proposed as an effective salvage regimen for some malignancies. Thus, we sought to evaluate this approach for young patients with relapsed or refractory bone tumors. Twelve patients with refractory bone tumors (two with Ewing sarcoma, two with chondrosarcoma, and eight with osteosarcoma) received salvage treatment with sorafenib. All patients had standard tumor imaging and laboratory evaluation. All toxicities were documented. At the time of the beginning of sorafenib treatment median age among 12 patients was 18 years (range 4.1–27.9 years), eight were male, and eight had osteosarcoma. All received sorafenib because of relapse. Seven patients were treated parallel to other standard chemotherapy. Overall response rate was 75%. Median time to sorafenib time to progression for patients with osteosarcoma was 4 months (range 1.8–7.9 months). Four patients (33%) are alive, in that two with no evidence of disease with a median follow-up of 41 months (range 26.5–60.9 months). The estimated 5 year overall survival (OS) for the whole group was 64.49%. There were no serious toxicities. Sorafenib is well-tolerated in young patients with bone tumors, and particularly could be an option for patients with metastatic disease and refractory osteosarcoma. Sorafenib only allows to extend OS and different procedures are needed to achieve permanent remission. This regimen deserves further investigation in the upfront management of patients with high-risk bone tumors. 相似文献

Lessons Learned
- Apatinib has potential as an effective and safe second‐line or higher treatment for patients with chemotherapy‐refractory esophageal squamous cell carcinoma (ESCC).
- Clinical safety is of potential concern when administering apatinib to patients with uncontrolled esophageal lesions or severe invasion of trachea, bronchi, or major blood vessels.
- To the best of the authors'' knowledge, this is the first prospective phase II study to investigate apatinib for patients with chemotherapy‐refractory ESCC. Apatinib could provide an alternative option for ESCC after first‐line or higher therapy in carefully selected patients.

BackgroundHigh-grade meningioma (HGM) is difficult to treat, and recurrent HGM after radiotherapy has an especially poor prognosis. We retrospectively analyzed the cases of 44 consecutive patients with recurrent and refractory HGM who were treated by reactor-based boron neutron capture therapy (BNCT).MethodsIn 2005–2019, we treated 44 recurrent and refractory HGMs by reactor-based BNCT. We analyzed the patients’ tumor shrinkage, overall survival (OS) after initial diagnosis, OS after BNCT, progression-free survival (PFS) post-BNCT, and treatment failure patterns.ResultsThe median OS (mOS) after BNCT and mOS after initial diagnosis were 29.6 (95% CI: 16.1–40.4) and 98.4 (95% CI: 68.7–169.4) months, respectively. The median follow-up after BNCT was 26 (6.4–103) months. The grade 2 (20 cases) and 3 (24 cases) post-BNCT mOS values were 44.4 (95% CI: 27.4–not determined) and 21.55 (10.6–30.6) months, respectively (P = .0009). Follow-up images were obtained from 36 cases at >3 months post-BNCT; 35 showed tumor shrinkage during the observation period. The post-BNCT median PFS (mPFS) of 36 cases was 13.7 (95% CI: 8.3–28.6) months. The post-BNCT mPFS values in patients with grade 2 and 3 disease were 24.3 (95% CI: 9.8–not determined) and 9.4 (6.3–14.4) months, respectively (P = .0024). Local recurrence was observed in only 22.2% of cases. These results showed good local tumor control and prolonged survival for recurrent HGM cases.ConclusionsMost of these cases had relatively large tumor volumes. The proportion of grade 3 patients was extremely high. Our patients thus seemed to have poor prognoses. Nevertheless, reactor-based BNCT exerted relatively good local control and favorable survival for recurrent and refractory HGMs. 相似文献

Background:
To evaluate surgical outcome and survival benefit after quaternary cytoreduction (QC) in epithelial ovarian cancer (EOC) relapse.Methods:
We systematically evaluated all consecutive patients undergoing QC in our institution over a 12-year period (October 2000–January 2012). All relevant surgical and clinical outcome parameters were systematically assessed.Results:
Forty-nine EOC patients (median age: 57; range: 28–76) underwent QC; in a median of 16 months (range:2–142) after previous chemotherapy. The majority of the patients had an initial FIGO stage III (67.3%), peritoneal carcinomatosis (77.6%) and no ascites (67.3%). At QC, patients presented following tumour pattern: lower abdomen 85.7% middle abdomen 79.6% and upper abdomen 42.9%. Median duration of surgery was 292 min (range: a total macroscopic tumour clearance could be achieved. Rates of major operative morbidity and 30-day mortality were 28.6% and 2%, respectively.Mean follow-up from QC was 18.41 months (95% confidence interval (CI):12.64–24.18) and mean overall survival (OS) 23.05 months (95% CI: 15.5–30.6). Mean OS for patients without vs any tumour residuals was 43 months (95% CI: 26.4–59.5) vs 13.4 months (95% CI: 7.42–19.4); P=0.001. Mean OS for patients who received postoperative chemotherapy (n=18; 36.7%) vs those who did not was 40.5 months (95% CI: 27.4–53.6) vs 12.03 months (95% CI: 5.9–18.18); P<0.001.Multivariate analysis indentified multifocal tumour dissemination to be of predictive significance for incomplete tumour resection, higher operative morbidity and lower survival, while systemic chemotherapy subsequent to QC had a protective significant impact on OS. No prognostic impact had ascites, platinum resistance, high grading and advanced age.Conclusion:
Even in this highly advanced setting of the third EOC relapse, maximal therapeutic effort combining optimal surgery and chemotherapy appear to significantly prolong survival in a selected patients ‘group''. 相似文献11.

Background
Antiangiogenic therapy has shown improved clinical outcome in metastatic colorectal cancer (mCRC). After the failure of standard treatments, regorafenib and TAS-102 would be recommended for patients with mCRC, however, they have not been approved in China during this study period.Patients and Methods
This pilot study aimed to assess the efficacy and safety of apatinib, a novel oral inhibitor targeting vascular endothelial growth factor receptor 2, as third-line treatment for patients with mCRC refractory to standard therapies. In this retrospective study, all patients received apatinib treatment until progressive disease (PD), death, unacceptable toxicity, and curative surgery. The dose or treatment schedule was modified according to the physician's discretion according to the toxicity profiles.Results
Between March 2015 and June 2017, 36 patients were enrolled and eligible for evaluation of the safety and efficacy. One patient (2.8%) achieved complete response, 3 (8.3%) achieved partial response, 24 (66.7%) achieved stable disease, and 8 (22.2%) PD. The objective response rate and the disease control rate were 11.1% (4 of 36), and 77.8% (28 of 36), respectively. Moreover, the median overall survival (OS) since the initiation of first-line treatment was 33.2 months. The median progression-free survival (PFS) and median OS from apatinib treatment were 4.8 and 10.1 months, respectively. Intergroup analysis showed that there was no significant difference in median PFS and median OS between patients who were previously treated with and without bevacizumab. The most common Grade 3 to 4 adverse reactions were hand-foot syndrome, hypertension, and proteinuria.Conclusion
Our results suggested that apatinib was active as a third-line treatment of refractory mCRC with a manageable tolerability profile. In addition, preliminary data suggested that the efficacy of apatinib would not be affected by previous bevacizumab treatment. Further prospective randomized controlled clinical trials are urgently needed. 相似文献12.

We reviewed patient and health care provider (HCP) surveys performed through the REaCT program. The REaCT team has performed 15 patient surveys (2298 respondents) and 13 HCP surveys (1033 respondents) that have addressed a broad range of topics in breast cancer management. Over time, the proportion of surveys distributed by paper/regular mail has fallen, with electronic distribution now the norm. For the patient surveys, the median duration of the surveys was 3 months (IQR 2.5–7 months) and the median response rate was 84% (IQR 80–91.7%). For the HCP surveys, the median survey duration was 3 months (IQR 1.75–4 months), and the median response rate, where available, was 28% (IQR 21.2–49%). The survey data have so far led to: 10 systematic reviews, 6 peer-reviewed grant applications and 19 clinical trials. Knowledge users should be an essential component of clinical research. The REaCT program has integrated surveys as a standard step of their trials process. The COVID-19 pandemic and reduced face-to-face interactions with patients in the clinic as well as the continued importance of social media highlight the need for alternative means of distributing and responding to surveys. 相似文献

Children with a brain tumor treated with high-dose busulfan-thiotepa with autologous stem cell transplantation (ASCT) and radiation therapy (RT) often experience radiographic changes during follow-up. The purpose of the study was to identify the incidence, time course, risk factors, and clinical outcome of this complication. From May 1988 through May 2007, 110 patients (median age, 3.6 years; range, 1 month to 15.3 years) with a brain tumor had received 1 course of high-dose busulfan-thiotepa with stem cell rescue, followed or preceded by RT as part of their treatment. All MRI follow-up examinations were systematically reviewed. Twenty-three patients (21%) developed neuroradiological abnormalities at a median time of 9.2 months (range, 5.6–17.3 months) after ASCT. All contrast-enhancing lesions appeared in patients who had received RT after ASCT and were localized inside the 50–55Gy isodoses. They disappeared in 14 of 23 patients after a median time of 8 months (range, 3–17 months), leaving microcalcifications in some cases. The presence of MRI abnormalities was an independent prognostic factor for overall survival in the multivariate analysis (hazard ratio, 0.12; 95% confidence interval [CI], 0.04–0.33), with a 5-year overall survival rate of 84% among patients with MRI abnormalities (95% CI, 62–94), compared with 27% (95% CI, 19–37) among those without lesions. MRI-detectable pseudoprogression is a common early finding in children treated with high-dose busulfan-thiotepa followed by radiation therapy and is correlated with a better outcome. 相似文献

Bendamustine demonstrated synergistic efficacy with bortezomib against multiple myeloma (MM) cells in vitro and seems an effective treatment for relapsed-refractory MM (rrMM). This phase II study evaluated bendamustine plus bortezomib and dexamethasone (BVD) administered over six 28-day cycles and then every 56 days for six further cycles in patients with rrMM treated with ⩽4 prior therapies and not refractory to bortezomib. The primary study end point was the overall response rate after four cycles. In total, 75 patients were enrolled, of median age 68 years. All patients had received targeted agents, 83% had 1–2 prior therapies and 33% were refractory to the last treatment. The response rate⩾partial response (PR) was 71.5% (16% complete response, 18.5% very good PR, 37% partial remission). At 12 months of follow-up, median time-to-progression (TTP) was 16.5 months and 1-year overall survival was 78%. According to Cox regression analysis, only prior therapy with bortezomib plus lenalidomide significantly reduced TTP (9 vs 17 months; hazard ratio=4.5; P=0.005). The main severe side effects were thrombocytopenia (30.5%), neutropenia (18.5%), infections (12%), neuropathy (8%) and gastrointestinal and cardiovascular events (both 6.5%). The BVD regimen is feasible, effective and well-tolerated in difficult-to-treat patients with rrMM. 相似文献

BackgroundPatients with metastatic breast cancer (MBC) are living longer, but the development of brain metastases often limits their survival. We conducted a systematic review and meta-analysis to determine the incidence of brain metastases in this patient population.MethodsArticles published from January 2000 to January 2020 were compiled from four databases using search terms related to breast cancer, brain metastasis, and incidence. The overall and per patient-year incidence of brain metastases were extracted from studies including patients with human epidermal growth factor receptor-2 positive (HER2+), triple negative, and hormone receptor (HR)+/hormone receptor negative (HER2−) MBC; pooled overall estimates for incidence were calculated using random effects models.Results937 articles were compiled, and 25 were included in the meta-analysis. Incidence of brain metastases in patients with HER2+ MBC, triple negative MBC, and HR+/HER2− MBC was reported in 17, 6, and 4 studies, respectively. The pooled cumulative incidence of brain metastases was 31% for the HER2+ subgroup (median follow-up: 30.7 months, IQR: 24.0–34.0), 32% for the triple negative subgroup (median follow-up: 32.8 months, IQR: 18.5–40.6), and 15% among patients with HR+/HER2− MBC (median follow-up: 33.0 months, IQR: 31.9–36.2). The corresponding incidences per patient-year were 0.13 (95% CI: 0.10–0.16) for the HER2+ subgroup, 0.13 (95%CI: 0.09–0.20) for the triple negative subgroup, and only 0.05 (95%CI: 0.03–0.08) for patients with HR+/HER2− MBC.ConclusionThere is a high incidence of brain metastases among patients with HER2+ and triple negative MBC. The utility of a brain metastases screening program warrants investigation in these populations. 相似文献

BackgroundTo report on our institutional experience using Proton stereotactic body radiation therapy (SBRT) for patients with liver metastases.MethodsAll patients with liver metastases treated with Proton SBRT between September 2012 and December 2017 were retrospectively analyzed. Local control (LC) and overall survival (OS) were estimated using the Kaplan-Meier method calculated from the time of completion of Proton SBRT. LC was defined according to Response Evaluation Criteria in Solid Tumors (RECIST) guidelines (version 1.1). Toxicity was graded according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.ResultsForty-six patients with 81 lesions were treated with Proton SBRT. The median age was 65.5 years old (range, 33–86 years) and the median follow up was 15 months (range, 1–54 months). The median size of the gross tumor volume (GTV) was 2.5 cm (range, 0.7–8.9 cm). Two or more lesions were treated in 56.5% of patients, with one patient receiving treatment to a total of five lesions. There were 37 lesions treated with a biologically effective dose (BED) ≤60, 9 lesions with a BED of 61–80, 22 lesions with a BED of 81–100, and 13 lesions with a BED >100. The 1-year and 2-year LC for all lesions was 92.5% (95% CI, 82.7% to 96.8%). The grade 1 and grade 2 toxicity rates were 37% and 6.5%, respectively. There were no grade 3 or higher toxicities and no cases of radiation-induced liver disease (RILD).ConclusionsProton SBRT for the treatment of liver metastases has promising LC rates with the ability to safely treat multiple liver metastases. Accrual continues for our phase II trial treating liver metastases with Proton SBRT to 60 GyE (Gray equivalent) in 3 fractions. 相似文献
