The Assessment of Risk Factors for Long-term Survival Outcome in ypN0 Patients With Rectal Cancer After Neoadjuvant Therapy and Radical Anterior Rese…
2021
Abstract Background The main negative prognostic factors in patients with rectal cancer after radical treatment include regional lymph node involvement, lymphovascular invasion, and perineural invasion. However, some patients still develop cancer recurrence despite the absence of the above risk factors. The aim of the study was to assess clinicopathological factors influencing long-term oncologic outcomes in ypN0M0 rectal cancer patients after neoadjuvant therapy and radical anterior resection. Methods A retrospective survival analysis was performed on a group of 195 patients. We assessed clinicopathological factors which included tumor regression grade, number of lymph nodes in the specime…
Peritoneal Carcinomatosis and Multi-Organ Metastases are Prognostic Factors in Colorectal Cancer: A Retrospective Analysis
2016
Background: Peritoneal carcinomatosis and multi-organ metastases might be prognostic factors in patients with advanced colorectal cancer and inoperable metastases at diagnosis. Methods: A retrospective study was performed to examine the relationship between patient clinical characteristics and prognosis in patients with colorectal cancer and indication for first-line systemic chemotherapy. Results: One hundred and twelve patients were accrued. According to univariate analysis, peritoneal carcinomatosis, lack of primary tumour resection and multi-organ metastases were associated with poor overall survival. According to multivariate analysis, patients with peritoneal carcinomatosis and patie…
A Long-Term Extension Study of Bevacizumab in Patients With Solid Tumors
2021
Abstract Background Bevacizumab has been studied in numerous clinical trials in multiple types of cancer; however, patients may receive bevacizumab over an extended period of time. This study assessed the long‐term safety and tolerability of bevacizumab among patients with solid tumors. Materials and Methods Patients enrolled in a Roche/Genentech‐sponsored trial who had derived benefit from bevacizumab therapy as monotherapy or in combination with anticancer drugs were eligible for continuation of bevacizumab in this long‐term extension (LTE) study. The primary endpoints were the incidence of adverse events (AEs) of Common Terminology Criteria for AEs (CTCAE) grade ≥3 related to bevacizumab…
“Bevacizumab (Bev), irinotecan (IRI), folinic acid (FA), and 5-fluorouracil (FU) every 2 weeks (BIFF regimen) as first-line treatment for metastatic …

e15067 Background: The IRIFAFU regimen produced in MCRC pts a consistent activity (RR, 33% [95% CI, 27–39%], PFS, 7.4 [95% CI, 6.5–8.3] mo.) in 2 consecutive randomized SICOG trials . Bev was proven to significantly improve the efficacy of IFL regimen. Here we report the safety and activity results of the BIFF regimen as first-line treatment of MCRC. Patients: From Feb 2007 to Jul 2008, 95 pts with MCRC were treated: so far, 85 pts were evaluated for safety: M/F were 47/38, median age (range) was 64 (35–78) yrs. Fifty-six pts had a colon, and 29 pts a rectal carcinoma. ECOG PS was 0 (63 pts, 74%), or 1 (22 pts, 26%). Thirty-four (40%) pts had 1 site, 33 (39%) 2 sites, and 18 (21%) pts ≥3 s…

Lynch syndrome (LS) increases cancer risk. There is considerable individual variation in LS cancer occurrence, which may be moderated by lifestyle factors, such as body weight and physical activity (PA). The potential associations of lifestyle and cancer risk in LS are understudied. We conducted a retrospective study with cancer register data to investigate associations between body weight, PA, and cancer risk among Finnish LS carriers. The participants (n = 465, 54% women) self-reported their adulthood body weight and PA at 10-year intervals. Overall cancer risk and colorectal cancer (CRC) risk was analyzed separately for men and women with respect to longitudinal and near-term changes in …
The impact of TP53 mutation on high-risk rectal cancer patients treated within the EXPERT-C trial, a randomized phase II study of neoadjuvant oxalipl…
2012
e14088 Background: The EXPERT-C trial randomised 165 patients into neoadjuvant CAPOX and CRT ± cetuximab and demonstrated a significant increase in radiological response (RR) and overall survival (OS) with cetuximab in KRAS/BRAF wild type (WT) rectal cancer (Dewdney et al JCO in press). TP53 mutation has been associated with worse CRT response and survival in rectal cancer and could lead to stimulation of PI3K signalling pathway, thus potential resistance to cetuximab. This analysis evaluates the impact of TP53 mutation in the EXPERT-C trial. Methods: FFPE tissue from biopsy (n=102) and resection specimens (n=99) were analysed for TP53 mutations (exons 5-8) using a multiplex PCR method fol…
FCγRIIa and FCγRIIIa polymorphisms (SNPs) and cetuximab (C) benefit in the EXPERT-C trial.
2014
3573 Background: FCγRIIa-H131R and FCγRIIIa-V158F SNPs have been reported to enhance the immune-mediated effects of monoclonal antibodies including cetuximab (C) in metastatic colorectal cancer (CR...
Abstract LB-220: Translational research with RG7160 (GA201) leads to a phase II clinical study in combination with FOLFIRI in 2nd line metastatic col…
2012
Abstract GA201 is a novel dual-acting humanized, engineered IgG1 anti-EGFR mAb designed to enhance ADCC in combination with signaling inhibition. Superior efficacy was demonstrated versus cetuximab in orthotopic CRC xenograft models. Preclinical data indicated an increase in macrophages (4-5 fold) and NK cells (2-3 fold) infiltration in tumors treated with GA201 compared to cetuximab. In a phase I clinical study objective responses and long lasting disease stabilizations were observed. A marked reduction in circulating NK cells and an increased infiltration of immune cells into skin rash was seen. Preliminary evidence of the enhanced ADCC capacity of GA201 was investigated in 25 third line …
Clinical results of EGFR-targeted therapies in advanced colorectal cancer
2008
Abstract This paper is an updated review of the pre-clinical rationale and clinical results of new EGFR-targeted agents – cetuximab and panitumumab – employed in the management of advanced/ metastatic colorectal cancer. The addition of either biologic agent or last generation standard chemotherapy regimens – FOLFIRI and FOLFOX – has yielded better results as compared to those reported for chemotherapy alone. These results have been obtained without a significant increase in severe toxicity with the exception of skin side-effects.
