Preoperative chemoradiation therapy with capecitabine/oxaliplatin and cetuximab in rectal cancer: long-term results of a prospective phase 1/2 study.

Hide Abstract
We have previously shown that the addition of cetuximab to chemoradiation therapy failed to improve complete response rates (pCR) in rectal cancer. Here we report the long-term results of the cetuximab added to preoperative radiation therapy with capecitabine and oxaliplatin (CET-CAPOX-RT) phase 1/2 study that evaluated preoperative chemoradiation with cetuximab, capecitabine, and oxaliplatin in patients with rectal cancer.

Analysis of Bevacizumab-based Preoperative Radiochemotherapy in Patients with Locally Advanced Rectal Cancer on Surgery-associated Spectrum of Complications.

Show Abstract
Hide Abstract
Preoperative radiochemotherapy (RCT) is a standard of care for patients with locally advanced rectal cancer (LARC; stages II and III). Results of our phase II study (BevXelOx-RT) have shown that this regimen is feasible but without a significant improvement of pathological complete response. Whether preoperatively administered bevacizumab, due to its specific toxicity profile, leads to increased rates of surgical complications is currently a subject for debate. This analysis focusses on the surgery-associated spectrum of complications.

Hide Abstract
BACKGROUND: Preoperative radiochemotherapy (RCT) with 5-FU or capecitabine is the standard of care for patients with locally advanced rectal cancer (LARC). Preoperative RCT achieves pathological complete response rates (pCR) of 10-15%. We conducted a single arm phase II study to investigate the feasibility and efficacy of addition of bevacizumab and oxaliplatin to preoperative standard RCT with capecitabine. METHODS: Eligible patients had LARC (cT3-4; N0/1/2, M0/1) and were treated with preoperative RCT prior to planned surgery. Patients received conventionally fractionated radiotherapy (50.4 Gy in 1.8 Gy fractions) and simultaneous chemotherapy with capecitabine 825 mg/m2 bid (d1-14, d22-35) and oxaliplatin 50 mg/m2 (d1, d8, d22, d29). Bevacizumab 5 mg/kg was added on days 1, 15, and 29. The primary study objective was the pCR rate. RESULTS: 70 patients with LARC (cT3-4; N0/1, M0/1), ECOG < 2, were enrolled at 6 sites from 07/2008 through 02/2010 (median age 61 years [range 39--89], 68% male). At initial diagnosis, 84% of patients had clinical stage T3, 62% of patients had nodal involvement and 83% of patients were M0. Mean tumor distance from anal verge was 5.92 cm (+/- 3.68). 58 patients received the complete RCT (full dose RT and full dose of all chemotherapy). During preoperative treatment, grade 3 or 4 toxicities were experienced by 6 and 2 patients, respectively: grade 4 diarrhea and nausea in one patient (1.4%), respectively, grade 3 diarrhea in 2 patients (3%), grade 3 obstipation, anal abscess, anaphylactic reaction, leucopenia and neutropenia in one patient (1.4%), respectively. In total, 30 patients (46%) developed postoperative complications of any grade including one gastrointestinal perforation in one patient (2%), wound-healing problems in 7 patients (11%) and bleedings in 2 patients (3%). pCR was observed in 12/69 (17.4%) patients. Pathological downstaging (ypT < cT and ypN <= cN) was achieved in 31 of 69 patients (44.9%). All of the 66 operated patients had a R0 resection. 47 patients (68.1%) underwent sphincter preserving surgery. CONCLUSIONS: The addition of bevacizumab and oxaliplatin to RCT with capecitabine was well tolerated and did not increase perioperative morbidity or mortality. However, the pCR rate was not improved in comparison to other trials that used capecitabine or capecitabine/oxaliplatin in preoperative radiochemotherapy.

Margins! Margins. Margins? How Important Is Margin Status in Breast-Preserving Therapy?
Breast Care (Basel)
PUBLISHED: 10-31-2011
Show Abstract
Hide Abstract
Margin status is surely a prognostic factor in patients undergoing breast-conserving therapy, but its impact is probably overestimated in case of adequate adjuvant radiotherapy. Radiotherapy improves local control after excision of the primary tumor in all subgroups of patients. There is, in contrast, no evidence that a certain margin width or a re-resection improves local control.

Does Radiotherapy Have Curative Potential in Metastatic Patients? The Concept of Local Therapy in Oligometastatic Breast Cancer.
Breast Care (Basel)
PUBLISHED: 10-13-2011
Show Abstract
Hide Abstract
In 1995, Hellmann and Weichselbaum defined for the first time the term oligometastases which is used to describe limited metastasis with a maximum of 3-4 clinically detectable metastases. It is assumed that these patients have a better prognosis and that local treatment of the metastases plays a significant part in the further development of the disease. Therefore, these patients could benefit from a curative local therapy of the manifested metastases. Local therapy measures include mainly radiotherapeutic methods alongside invasive ablative processes, such as surgical resection and radiofrequency ablation. Patients subjected to radiation therapy benefit especially from the usage of modern precision technology as it reduces the radiation exposure to the normal tissue, and because short radiation sessions with escalating doses are possible (e.g. radiation surgery, image-assisted radiation therapy, stereotactic radiation). Initial clinical studies show very good local tumor control rates which are on a par with resection and ablative methods, but with very few side effects and risks. This article summarizes the integration of the concept of oligometastases in the radiotherapy of limited metastatic breast cancer.

EGF61 polymorphism predicts complete pathologic response to cetuximab-based chemoradiation independent of KRAS status in locally advanced rectal cancer patients.

Hide Abstract
Cetuximab has shown significant clinical activity in metastatic colon cancer. However, cetuximab-containing neoadjuvant chemoradiation has not been shown to improve tumor response in locally advanced rectal cancer patients in recent phase I/II trials. We evaluated functional germline polymorphisms of genes involved in epidermal growth factor receptor pathway, angiogenesis, antibody-dependent cell-mediated cytotoxicity, DNA repair, and drug metabolism, for their potential role as molecular predictors for clinical outcome in locally advanced rectal cancer patients treated with preoperative cetuximab-based chemoradiation.

Phase II trials in locally advanced rectal cancer have shown that cetuximab-based neoadjuvant radiochemotherapy is feasible but without an improvement in complete pathologic response rates. Our goal was to identify patients who would benefit from cetuximab-based neoadjuvant chemoradiation measuring gene expression levels of proteins involved in tumor growth [endothelial growth factor receptor (EGFR)], angiogenesis [VEGF, VEGF receptors 1 and 2 (VEGFR1, VEGFR2)], DNA repair [excision repair cross-complementing 1 (ERCC1)], and drug metabolism [thymidylate synthetase (TS)]. We also determined mutation status of KRAS and BRAF.

Concurrent chemoradiation of metastases with capecitabine and oxaliplatin and 3D-CRT in patients with oligometastatic colorectal cancer: results of a phase I study.
Radiat Oncol
Show Abstract
Hide Abstract
Local control appears to be an important treatment aim in patients with limited metastases (oligometastases) of colorectal cancer (CRC). Those patients show a favourable prognosis, if--in addition to the local effective treatment--an occurrence of new metastases may also be postponed by effective systemic therapy. The purpose of this dose escalation phase I study was to establish the efficacy of local radiotherapy (RT) of oligometastatic CRC with a concurrent standard chemotherapy regimen.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
