Phase II trial of concurrent sunitinib and image-guided radiotherapy for oligometastases.

ABSTRACT: Preclinical data suggest that sunitinib enhances the efficacy of radiotherapy. We tested the combination of sunitinib and hypofractionated image-guided radiotherapy (IGRT) in a cohort of patients with historically incurable distant metastases.Twenty five patients with oligometastases, defined as 1-5 sites of active disease on whole body imaging, were enrolled in a phase II trial from 2/08 to 9/10. The most common tumor types treated were head and neck, liver, lung, kidney and prostate cancers. Patients were treated with the recommended phase II dose of 37.5 mg daily sunitinib (days 1-28) and IGRT 50 Gy (days 8-12 and 15-19). Maintenance sunitinib was used in 33% of patients. Median follow up was 17.5 months (range, 0.7 to 37.4 months).The 18-month local control, distant control, progression-free survival (PFS) and overall survival (OS) were 75%, 52%, 56% and 71%, respectively. At last follow-up, 11 (44%) patients were alive without evidence of disease, 7 (28%) were alive with distant metastases, 3 (12%) were dead from distant metastases, 3 (12%) were dead from comorbid illness, and 1 (4%) was dead from treatment-related toxicities. The incidence of acute grade ? 3 toxicities was 28%, most commonly myelosuppression, bleeding and abnormal liver function tests.Concurrent sunitinib and IGRT achieves major clinical responses in a subset of patients with oligometastases.ClinicalTrials.gov NCT00463060.

Project description:PurposeThe use of concurrent doublet chemotherapy with radiation for locoregionally advanced cervical cancer (LACC) is limited by gastrointestinal and hematologic toxicity. By reducing radiation dose to bowel and bone marrow, image guided intensity modulated radiation therapy (IG-IMRT) may improve chemotherapy tolerance. The goal of this study was to determine whether IG-IMRT could lead to improved tolerance to concurrent cisplatin and gemcitabine for LACC.Methods and materialsWe conducted an open-label, nonrandomized, prospective phase 1 dose escalation trial at a tertiary academic cancer center (ClinicalTrials.gov identifier: NCT01554410). We enrolled patients with stage IB-IVA cervical cancer, with either an intact cervix or posthysterectomy with residual/recurrent pelvic or paraortic nodal involvement, undergoing radical pelvic or extended field chemoradiation therapy. Treatment consisted of chemoradiation with IG-IMRT (45-47.6 Gy, 25-28 fractions to the pelvis ± paraortic nodes with simultaneous nodal boost to 53.2-59.4 Gy, 28 fractions) plus 5 cycles of concurrent weekly cisplatin 40 mg/m2 with escalating doses of gemcitabine (50, 75, 100, or 125 mg/m2). Cohorts were separated preregistration according to whether the patient received pelvic or extended field IG-IMRT and whether gemcitabine followed (CG) or preceded (GC) cisplatin delivery. Dose-limiting toxicity (DLT) events were monitored up to 30 days after chemoradiation therapy. The primary endpoint was maximum tolerated dose (MTD) resulting in DLT probability ≤20%.ResultsBetween February 2011 and June 2019, 35 patients were registered. Overall, 7 patients (20.0%) experienced DLTs. For the pelvic field cohort, the estimated MTD was 100 mg/m2 with GC sequencing, which is higher than the previously reported MTD for this regimen. The extended field cohort was closed after 2 of 3 patients experienced a DLT at the first dose level.ConclusionsIG-IMRT can permit higher doses of concurrent gemcitabine with cisplatin and pelvic radiation for LACC. However, acute toxicity remains a factor with this regimen, depending on radiation volume and chemotherapy sequencing.

Project description:ImportancePalliative radiotherapy (RT) is generally recommended for older patients with esophageal squamous cell carcinoma (ESCC) with poor prognosis. A new combination treatment is therefore needed.ObjectiveTo assess the efficacy and toxicity of RT plus icotinib vs RT alone in older patients with ESCC.Design, setting, and participantsThis randomized, multicenter, open-label, phase II clinical trial was conducted in China, with enrollment between January 1, 2015, and October 31, 2016. Patients aged 70 years or older with clinical stage T2 to T4, N0/1, M0/1a unresectable (because of comorbidities, T4 disease, unresectable lymph node, or refused surgery) ESCC were randomized 1:1 to receive RT plus icotinib or RT alone. Radiation was prescribed at 60 Gy in 30 fractions in both groups, and icotinib was administered at a dosage of 125 mg 3 times a day in the RT plus icotinib group. The last follow-up was completed on June 30, 2019, and data were analyzed from July 1 to September 30, 2019.InterventionsPatients were randomized to either RT plus icotinib or RT alone.Main outcomes and measuresThe primary end point was overall survival (OS). Treatment-related toxic effects were evaluated. Immunohistochemistry was performed to analyze epidermal growth factor receptor (EGFR) expression if available.ResultsA total of 127 patients (median age, 76 years [range, 70-91 years]; 76 men [59.8%]) were enrolled and were eligible for survival analysis. Median OS was 24.0 (95% CI, 22.2-25.8) months in the RT plus icotinib group vs 16.3 (95% CI, 13.8-18.8) months in the RT group (hazard ratio, 0.53; 95% CI, 0.33-0.87; P = .008). No difference was observed in grades 3 or 4 adverse events. Patients with EGFR overexpression had a significantly better median overall survival (not reached vs 16.3 months [range, 2.6-45.1 months]; P = .03) in the RT plus icotinib group.Conclusions and relevanceIn this randomized clinical trial, icotinib plus RT was well tolerated and improved OS in older patients with ESCC relative to RT alone. Patients with EGFR overexpression benefitted more from icotinib with RT.Trial registrationClinicalTrials.gov Identifier: NCT02375581.

Project description:After definitive chemoradiotherapy for non-metastatic nasopharyngeal carcinoma (NPC), more than 10% of patients will experience a local recurrence. Salvage treatments present significant challenges for locally recurrent NPC. Surgery, stereotactic ablative body radiotherapy, and brachytherapy have been used to treat locally recurrent NPC. However, only patients with small-volume tumors can benefit from these treatments. Re-irradiation with X-ray-based intensity-modulated radiotherapy (IMXT) has been more widely used for salvage treatment of locally recurrent NPC with a large tumor burden, but over-irradiation to the surrounding normal tissues has been shown to cause frequent and severe toxicities. Furthermore, locally recurrent NPC represents a clinical entity that is more radio-resistant than its primary counterpart. Due to the inherent physical advantages of heavy-particle therapy, precise dose delivery to the target volume(s), without exposing the surrounding organs at risk to extra doses, is highly feasible with carbon-ion radiotherapy (CIRT). In addition, CIRT is a high linear energy transfer (LET) radiation and provides an increased relative biological effectiveness compared with photon and proton radiotherapy. Our prior work showed that CIRT alone to 57.5 GyE (gray equivalent), at 2.5 GyE per daily fraction, was well tolerated in patients who were previously treated for NPC with a definitive dose of IMXT. The short-term response rates at 3-6 months were also acceptable. However, no patients were treated with concurrent chemotherapy. Whether the addition of concurrent chemotherapy to CIRT can benefit locally recurrent NPC patients over CIRT alone has never been addressed. It is possible that the benefits of high-LET CIRT may make radiosensitizing chemotherapy unnecessary. We therefore implemented a phase I/II clinical trial to address these questions and present our methodology and results.The maximal tolerated dose (MTD) of re-treatment using raster-scanning CIRT plus concurrent cisplatin will be determined in the phase I, dose-escalating stage of this study. CIRT dose escalation from 52.5 to 65 GyE (2.5 GyE × 21-26 fractions) will be delivered, with the primary endpoints being acute and subacute toxicities. Efficacy in terms of overall survival (OS) and local progression-free survival of patients after concurrent chemotherapy plus CIRT at the determined MTD will then be studied in the phase II stage of the trial. We hypothesize that CIRT plus chemotherapy can improve the 2-year OS rate from the historical 50% to at least 70%.Re-treatment of locally recurrent NPC using photon radiation techniques, including IMXT, provides moderate efficacy but causes potentially severe toxicities. Improved outcomes in terms of efficacy and toxicity profile are expected with CIRT plus chemotherapy. However, the MTD of CIRT used concurrently with cisplatin-based chemotherapy for locally recurrent NPC remains to be determined. In addition, whether the addition of chemotherapy to CIRT is needed remains unknown. These questions will be evaluated in the dose-escalating phase I and randomized phase II trials.
