Concurrent Chemoradiotherapy

Concurrent Chemoradiotherapy is a treatment modality that involves the simultaneous administration of chemotherapy and radiotherapy.
This approach is commonly used to treat various types of cancer, including head and neck, lung, and esophageal cancers.
The combination of these therapies can enhance the efficacy of treatment by targeting cancer cells through different mechanisms, leading to imporved outcomes for patients.
Selecting the optimal protocols and products for Concurrent Chemoradiotherapy can be challenging, which is why PubCompare.ai offers a powerful AI-driven platform to help researchers and clinicians easily locate the latest protocols, identify the best options, and streamline their research process.

Fresh-frozen tumor specimens from 293 consecutive CRC patients were retrieved from the tissue banks of the Royal Melbourne Hospital, Western Hospital and Peter MacCallum Cancer Center in Australia, and the H. Lee Moffitt Cancer Center in the United States; individuals who had received preoperative chemo- and/or radiotherapy or for whom tumor-derived total RNA was inadequate for microarray analysis (RIN < 6) were excluded. All patients gave informed consent, and this study was approved by the medical ethics committees of all sites. Patient median age at diagnosis was 67 years (range 26 to 92 years). All specimens were derived from primary carcinomas and were snap-frozen in liquid nitrogen immediately after surgery for storage at −80°C. Cases comprised 44 stage A, 95 stage B, 93 stage C and 61 stage D cancers; 252 were localized to the colon and 40 to the rectum, with one case missing this information. 22 of 94 patients who had stage B disease and 64 of 91 patients who had stage C disease had received standard adjuvant chemotherapy (either single agent 5-fluouracil/capecitabine or 5-fluouracil and oxaliplatin) or postoperative concurrent chemoradiotherapy (50.4 Gy in 28 fractions with concurrent 5-fluorouracil) according to hospital protocols. All patients were assessed annually. For stage B and C patients, follow-up and additional clinical data including patient gender and TNM staging were collected by Biogrid Australia 1 for Australian patients and the Moffitt Cancer Center Tumor Registry for US patients. The median duration of follow-up was 47.8 months (range 0.9 to 118.6 months) for the 140 patients without recurrence, and 19.1 months (range 1.6 to 93.7 months) for the 48 patients with local or distant recurrence. The median follow-up for all 188 patients was 37.2 months (range 0.9 to 118.6 months).
Total RNA was extracted using Trizol reagent (Invitrogen) from CRC samples containing >60% tumor cells. All samples included showed good integrity of 18S and 28S ribosomal bands (RIN > 6) using a 2100 Bioanalyzer (Agilent Technologies). Total RNA was labeled and hybridized to HG-U133Plus2.0 GeneChip arrays (Affymetrix) according to the manufacturer’s instructions. The microarray data on a subset of 174 tumors have been published previously (NCBI Gene Expression Omnibus, GSE5206 and GSE13067).
In addition, published gene expression data were retrieved for 42 stage A CRCs, 83 stage B, 73 stage C and 62 stage D CRCs analyzed as part of the Expression Project for Oncology (expO) 2 using HG-U133Plus2.0 GeneChip arrays (Affymetrix) (Supplementary Table S1). Of the 62 stage D CRCs, 32 were primary cancer and 30 were metastectomy specimens. None of the primary cancer patients had received preoperative therapy, but 17 metastectomy specimens were from patients who had received adjuvant chemotherapy treatment prior to resection. Data processing and analysis were performed using the statistical software package R (15 ) and appropriate Bioconductor packages (16 (link)).

This trial was designed to compare the toxicity and effectiveness of PSPT with that of standard IMRT, both with concurrent chemotherapy, for patients with locally advanced NSCLC (Appendix: Protocol). Patients were treated at The University of Texas MD Anderson Cancer Center and at Massachusetts General Hospital. The protocol was approved by the institutional review boards of both institutions, and all enrollees provided written informed consent to participate.
Eligibility criteria included age >18 years, Karnofsky Performance Status score ≥70, stage II–IIIB disease, or stage IV disease with a single brain metastasis, or recurrent tumor after surgical resection that could be treated definitively with concurrent chemoradiation, and baseline pulmonary function of forced expiratory volume in the first second of ≥1 liter. Patients who had received systemic chemotherapy regardless of response before enrollment were also eligible. Eligible patients consented to participate after they were evaluated and deemed suitable candidates for concurrent chemoradiation.
The primary endpoint was the first occurrence of either severe (grade ≥3) RP or local failure (LF). The choice to use two primary endpoints emphasized the importance of being free of RP, a potentially lethal form of toxicity, in addition to local disease control. From our historical data13 ,14 (link) we assumed 15% RP rates at 1 year in the IMRT group and 5% in the PSPT group; we further assumed a 25% LF rate in both groups (because the prescribed dose to tumor was the same in both arms by design). With a maximum of 150 randomized and evaluable patients, we would have 81% power to detect such a difference with a one-sided type I error rate of ≥10%. The posterior probability of PSPT being better than IMRT based on the primary endpoints was to be reported. The Bayesian adaptive design was constructed to possess the desirable frequentist properties. Detailed information on assumptions for the study design and trial operating characteristics can be found in the study protocol (Appendix: Protocol).

On the basis of our phase II study,15 (link) sample size calculations were made assuming a projected median survival of 56 months for patients assigned to group CRT and 39 months for those assigned to group S. With a two-sided type I error of 0.05 and a power of 80%, a randomization ratio of 1:1 between the experimental and control arms, 7 years of accrual, 2 years of follow-up, and two planned interim analyses, and with a 10% dropout rate taken into account, the intended number of randomly assigned patients was 430 (215 per arm). This study was powered to detect a two-sided 5% significance level hazard ratio (HR) of 0.72. The calculations were performed assuming exponential distribution.
All patients randomly assigned to a group (the intention-to-treat population) were included in the primary evaluation of OS. The per-protocol population was defined as all patients who received surgery. We included the per-protocol population in the analysis of postoperative complications. Only the patients who achieved R0 resection were included in the assessment of DFS. We included patients who received concurrent chemoradiotherapy in the analysis for toxicity of chemotherapy and radiotherapy.
OS and DFS were calculated using the Kaplan-Meier method and were then compared by the log-rank test. The rate of R0 resection, incidence of complications, and peritreatment mortality were compared with the χ2 test or Fisher’s exact test, if indicated. Univariate and multivariate analysis with the Cox proportional hazards model was used to investigate the effect of different factors on survival. Covariates included treatment, age (≤ 60 years v > 60 years), sex, tumor location, clinical T stage (T1 to T2 v T3 v T4) and clinical N stage (Appendix Fig A1, online only). We also used the Cox proportional hazards model to calculate HRs and 95% CIs. We performed two formal interim analyses on Jun 1, 2011, and Dec 31, 2015, after 123 and 451 patients had been enrolled. The significance threshold was defined by the O'Brien-Fleming type boundary 0.000527 in the first interim analysis, 0.014 in the second interim analysis, and 0.045 for the final analysis. The data cutoff for the analysis presented here was December 31, 2016. This trial is registered at ClinicalTrials.gov.

A variety of nCRT-related adverse reactions were evaluated, including bone marrow suppression, radioactive proctitis, intestinal obstruction or perforation, narrow lumen, anastomotic fistula, perianal skin injury, emesis, and hand-foot syndrome. Hand-foot syndrome was mainly associated with capecitabine treatment. During concurrent chemoradiotherapy, blood routine examinations and biochemical examinations were conducted weekly. RTOG radiation injury classification and Common Terminology Criteria for Adverse Events (CTCAE, Version 5) were adopted to assess adverse events. Grades 1 and 2 myelosuppression were considered mild, while grades 3 and 4 were considered moderate to severe. Similarly, grades 1 and 2 were defined as mild radiation proctitis, and grades 3 and 4 were defined as moderate to severe radiation proctitis. The remaining adverse reactions including intestinal obstruction or perforation, narrow lumen, anastomotic fistula, perianal skin injury, emesis, and hand-foot syndrome were evaluated by their occurrence or not.
