Objective:This study is a prospective randomized, double-blind, placebo-controlled study to evaluate the effect of calcium and magnesium (Ca/Mg) infusion on amelioration of oxaliplatin neuropathy, the dose-limiting toxicity. Methods:Sixty patients with resected colorectal carcinoma (CRC) planned to receive adjuvant oxaliplatin-containing regimen were randomly assigned to two arms; Arm A:patients received Ca/Mg were given as 1 gm Ca gluconate and 1 gm MgSO 4 in 250 mL of intravenous (IV) solution over 30 min pre and post oxaliplatin infusion, and Arm B:patients received 250 mL of IV solution without Ca/Mg over 30 min pre and post oxaliplatin infusion. Primary outcome was to assess percentage of patients with oxaliplatin-induced neurotoxicity. Neurotoxicity was assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 3.0. Results:Sixty patients in both arms were assessed, 30 with Ca/Mg infusion and 30 without. Patients developed neurotoxicity in arm A were significantly lower than that in arm B after the end of treatment; 7 (23.3%) and 14 (46.6%) respectively (P < 0.05), and significantly lower duration of neuropathy in months (8 ± 2.5 vs 18 ± 3) respectively (P < 0.001). Conclusion:Use of IV Ca/Mg showed a statistically significant reduction of peripheral neuropathy (PN) in patients with CRC receiving oxaliplatin in the adjuvant settings. 相似文献

Multiple systems have been developed for grading the adverse effects (AEs) of cancer treatment. The National Cancer Institute Common Toxicity Criteria (CTC) system has substantially evolved since its inception in 1983. The most recent version, CTCAE v3.0 (Common Terminology Criteria for Adverse Events version 3.0) represents the first comprehensive, multimodality grading system for reporting the acute and late effects of cancer treatment. The new CTC requires changes in the application of AE criteria including new guidelines regarding late effects, surgical and pediatric effects, multimodality issues, and for reporting the duration of an effect. It builds on the strengths of previous systems, represents a considerable effort among hundreds of participants, and signifies an international collaboration and consensus of the oncology research community. This article updates recent progress in the evolution of adverse effects grading systems and reviews the development of CTCAE v3.0. 相似文献

The Common Terminology Criteria for Adverse Events (CTCAE), version 3.0, and its predecessors, the Common Toxicity Criteria (CTC) versions 1.0 and 2.0, were developed under the direction of the Cancer Therapy Evaluation Program of the National Cancer Institute (NCI) in an effort to provide standard language for reporting adverse events that occur in NCI-sponsored clinical trials. Each successive version of the CTC has improved the accuracy, precision, and completeness of the criteria in an effort to standardize reporting. We believe that the current version of the CTCAE cannot adequately code the subacute adverse events that commonly occur with today's targeted therapies. 相似文献

PURPOSE: To assess the association between the dose distributions in the rectum and late Radiation Therapy Oncology Group and the European Organisation for Research and Treatment of Cancer (RTOG/EORTC), Late Effects of Normal Tissue SOMA, and Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 graded rectal toxicity among patients with prostate cancer treated with RT. METHODS AND MATERIALS: Included in the study were 124 patients who received three-dimensional conformal RT for prostate cancer to a total dose of 70 Gy in 2-Gy fractions. All patients completed questionnaires regarding rectum complaints before RT and during long-term follow-up. Late rectum Grade 2 or worse toxicity, according to RTOG/EORTC, LENT SOMA, and CTCAE v3.0 criteria, was analyzed in relation to rectal dose and volume parameters. RESULTS: Dose-volume thresholds (V40>or=65%, V50>or=55%, V65>or=45%, V70>or=20%, and a rectum volumeor=70 Gy (V70) was most predictive for late Grade 2 or worse rectal toxicity with each of the grading systems. The associations were strongest, however, with use of the LENT SOMA system. CONCLUSIONS: Volume effects for late radiation-induced rectal toxicity are present, but their clinical significance depends on the grading system used. This should be taken into account in the interpretation of studies reporting on radiation-induced rectal toxicity. 相似文献

PURPOSE: To better understand rectal toxicity after prostate brachytherapy, we employed the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE version 3.0), a comprehensive system with distinct and separately reported gastrointestinal adverse event items (unlike Radiation Therapy Oncology Group morbidity scoring), to evaluate item-specific postimplant rectal toxicities. METHODS AND MATERIALS: We analyzed 135 patients treated with brachytherapy +/- hormonal therapy, using CTCAE v3.0 to score acute/late rectal toxicities (median follow-up, 41 months). Dosimetric parameters were evaluated for ability to predict toxicities. RESULTS: Use of CTCAE yielded a novel rectal toxicity profile consisting of diarrhea, incontinence, urgency, proctitis, pain, spasms, and hemorrhage event rates. No item had a < 5% Grade 1-2 acute toxicity rate (except spasms). Rectal dosimetry predicted late toxicities: for diarrhea, 5% Grade 1 toxicity rate for %V25 (percent of rectal volume receiving 25% of prescribed prostate dose) < or = 25% vs. 60% for %V25 > 25% (p < 0.001); for maximum toxicity, 10% Grade 1 toxicity rate for %V10 < or = 40% vs. 44% for %V10 > 40% (p = 0.007). CONCLUSIONS: A comprehensive understanding of item-specific postimplant rectal toxicities was obtained using CTCAE. Rectal %V25 > 25% and %V10 > 40% predicted worse late diarrhea and maximum toxicity, respectively. 相似文献

We surveyed the current status and the differences of treatment of colorectal cancer using modified FOLFOX6 regimen, in two general hospitals, Sakai City Hospital (A hospital) and Takarazuka Municipal Hospital (B hospital) between April 2005 and November 2006, retrospectively. The numbers of examined patients were 33 and 17 in A and B hospitals, respectively. The grade of myelosuppression and peripheral neuropathy were evaluated according to Common Terminology Criteria for Adverse Events v 3.0(CTCAE v 3.0)and Neurotoxicity Criteria of DEBIOPHARM(DEB-NTC). The setting of dosage was differed in two hospitals. In A hospital, the dosages of oxaliplatin, 5-FU bolus and 5-FU continuous infusion were more than 90% of the standard one at first time, and were reduced with almost same degree in the appearance of adverse effects. On the other hand, in B hospital, the dosages of these drugs were reduced about 20% even at first administration and, especially, the dose of 5-FU bolus tended to be remarkable reduction. Of adverse events, the rates of the appearance of neutropenia more than grade 3 was 21.2% and 47.1%, in A and B hospitals, respectively. No difference in peripheral neuropathy was detected at both hospitals. In conclusion, the differences in these two hospitals were detected in the dosage setting and myelosuppression, not in non-hematological adverse effects. 相似文献

PURPOSE: To quantify the incidence and severity of acute local toxicity in head and neck cancer patients treated with radiotherapy (RT), with or without chemotherapy (CHT), using the Common Terminology Criteria for Adverse Events, version 3.0 (CTCAE v3.0), scoring system. METHODS AND MATERIALS: Between 2004 and 2006, 149 patients with head and neck cancer treated with RT at our center were prospectively evaluated for local toxicity during treatment. On a weekly basis, patients were monitored and eight toxicity items were recorded according to the CTCAE v3.0 scoring system. Of the 149 patients, 48 (32%) were treated with RT alone (conventional fractionation), 82 (55%) with concomitant CHT and conventional fractionation RT, and 20 (13%) with accelerated-fractionation RT and CHT. RESULTS: Severe (Grade 3-4) adverse events were recorded in 28% (mucositis), 33% (dysphagia), 40% (pain), and 12% (skin) of patients. Multivariate analysis showed CHT to be the most relevant factor independently predicting for worse toxicity (mucositis, dysphagia, weight loss, salivary changes). In contrast, previous surgery, RT acceleration and older age, female gender, and younger age, respectively, predicted for a worse outcome of mucositis, weight loss, pain, and dermatitis. The T-score method confirmed that conventional RT alone is in the "low-burden" class (T-score = 0.6) and suggests that concurrent CHT and conventional fractionation RT is in the "high-burden" class (T-score = 1.15). Combined CHT and accelerated-fractionation RT had the highest T-score at 1.9. CONCLUSIONS: The CTCAE v3.0 proved to be a reliable tool to quantify acute toxicity in head and neck cancer patients treated with various treatment intensities. The effect of CHT and RT acceleration on the acute toxicity burden was clinically relevant. 相似文献

Background: Brachytherapy in treatment of endometrial cancer patients is growing and therefore, evaluation ofmore feasible schedule has become of great importance. The purpose of current study was to evaluate the complicationsof accelerated short course high dose rate intravaginal brachytherapy (HDR IVB), a new brachytherapy approachwhich is a more feasible treatment option in developing countries. Method: From 2017 to 2018, 54 patients diagnosedwith endometrial cancer and FIGO stages IA to IIB who underwent total abdominal hysterectomy with a bilateralsalpingo-oophorectomy were enrolled in present study. They were treated with a total dose of 25 Gy in 5 fractionswhich was prescribed daily. A dose of 5 Gy was prescribed at a depth of 0.5 cm in the upper third and middle thirdof vagina. Adverse effects related to organs at risk consist of bladder, vagina and rectum were documented based onthe Common Terminology Criteria for Adverse Events v3.0 (CTCAE v3.0). Results: The accelerated short courseHDR IVB was well tolerated and no grade 3 or higher toxicities was reported for patients during the follow up period.There were no chronic rectal toxicities and only one patient showed chronic urinary toxicities. However, the incidencerate of vaginal toxicities at the end of 4-month and 8-month follow up periods was higher than acute toxicities andsignificantly lower in elderly group compared to younger group. Conclusion: Overall, the accelerated HDR IVB wassafe and was well tolerated in endometrial cancer patients and the incidence rate of undue complications were equal,if not less, in elderly patients compared to the younger ones. 相似文献

Primary aim of the phase II study is to assess the antitumoral activity of new agents and in a second step their therapeutic effectivity. In addition, toxicity will be assessed. For cytotoxic agents, tumor shrinkage, the socalled response, is the dominant parameter for evaluation. Nowadays, the Response Evaluation Criteria in Solid Tumors (RECIST) are widely used. For cytostatic agents with preponderance of tumor growth inhibition, the time interval to tumor progression has been proven to be the more relevant parameter. In addition, further parameters of clinical benefit are to be tested. Whether or not a parameter can be used as surrogate for a relevant endpoint has to be validated for each of them separately. For the assessment of toxicity, the Common Terminology Criteria for Adverse Events (CTCAE; current version 3.0) are used. The early phase II study allows to assess cumulative toxicity, pharmacokinetics, and pharmacokinetic-pharmacodynamic interactions. The socalled late phase II study focuses on the assessment of the therapeutic effect of both single-agent therapy and combinations of drugs and/or therapeutic modalities. The phase II study continues to be of high impact, especially for the testing of substances with well-defined molecular targets to identify those which will consecutively yield positive phase III trials out of a plethora of substances. 相似文献

BackgroundBortezomib-induced peripheral neuropathy (BiPN) is a dose-limiting adverse effect of bortezomib-based therapy for multiple myeloma (MM). The reporting of BiPN is variable because of the use of different neuropathy scales. Most investigators use the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE).Patients and MethodsWe prospectively evaluated the incidence of BiPN in treatment-naive patients with MM receiving weekly cyclophosphamide, bortezomib, and dexamethasone (CyBorD) in 28-day cycles using 3 neuropathy scores: Total Neuropathy Score—reduced (TNSr) and —clinical (TNSc), and NCI CTCAE v4.0.ResultsTwenty-six patients received CyBorD. Twenty patients completed follow-up. The rates of occurrence of BiPN were as follows: TNSr - 55% (n = 11), TNSc - 40% (n = 8), and NCI CTCAE - 45% (n = 9). All 3 scales showed worsening after treatment (P < .01). When compared to BiPN by TNSr, sensitivities for NCI CTCAE and TNSc were 77.8% and 88.9%, respectively. Specificity was 63.3% for both NCI CTCAE and TNSc. Among 12 patients who did not have BiPN by NCI CTCAE scale, 41.7% (n = 5) and 16.7% (n = 2) patients satisfied the criteria for BiPN by TNSr and TNSc, respectively. The higher detection rate of neuropathy by TNSr and TNSc is probably due to increment in scores that are allotted for increase in anatomic extent of sensorimotor involvement, unlike the NCI CTCAE scale, which requires functional limitation for increase in grade.ConclusionNCI CTCAE may be suboptimal in comparison to TNSr and TNSc in assessment of BiPN because it may miss worsening neuropathy without functional limitation. 相似文献
