Peptide Receptor Radionuclide Therapy Combined With Chemotherapy in Patients With Neuroendocrine Tumors
2019
Combinations of therapies may enhance therapeutic effects without significantly increasing the incidence of adverse events. However, there are few data regarding survival after concomitant chemotherapy and peptide receptor radionuclide therapy (PRRT) with [Lu]Lu-octreotate in patients with neuroendocrine tumors (NETs). Thus, we explored the outcome of this combination of therapies.Fifteen patients with somatostatin receptor-positive, rapidly progressive G2/G3 NETs during chemotherapy or PRRT alone from 2 German cancer centers were included in the retrospective analysis. The patients received a combination of PRRT and chemotherapy with temozolomide (n = 3) or temozolomide plus capecitabine (…
Multicenter Randomized Phase II Clinical Trial Comparing Neoadjuvant Oxaliplatin, Capecitabine, and Preoperative Radiotherapy With or Without Cetuxim…
2012
Purpose To evaluate the addition of cetuximab to neoadjuvant chemotherapy before chemoradiotherapy in high-risk rectal cancer. Patients and Methods Patients with operable magnetic resonance imaging–defined high-risk rectal cancer received four cycles of capecitabine/oxaliplatin (CAPOX) followed by capecitabine chemoradiotherapy, surgery, and adjuvant CAPOX (four cycles) or the same regimen plus weekly cetuximab (CAPOX+C). The primary end point was complete response (CR; pathologic CR or, in patients not undergoing surgery, radiologic CR) in patients with KRAS/BRAF wild-type tumors. Secondary end points were radiologic response (RR), progression-free survival (PFS), overall survival (OS), an…
Oxaliplatin and Capecitabine-Based Chemoradiotherapy for Gastric Cancer—An Extended Phase I MARGIT and AIO Trial
2008
Purpose Adjuvant 5-fluorouracil–based chemoradiotherapy has been shown to improve the prognosis of gastric cancer. To optimize these results, in the present study oxaliplatin and capecitabine were used instead of 5-fluorouracil. We sought to determine the maximum tolerated dose and the dose-limiting toxicities (DLT) of these drugs in combination with intensity-modulated radiotherapy. Methods and Materials Patients with resected adenocarcinoma of the stomach or the gastroesophageal junction were included. They received two cycles of induction chemotherapy (oxaliplatin and capecitabine [XelOx] regimen). Using standard Phase I methodology, patients received 45 Gy in 1.8-Gy fractions either in …
Prognostic role of the LCS6 KRAS variant in locally advanced rectal cancer: results of the EXPERT-C trial
2015
KRAS mutation has been reported as a marker of radio-resistance in rectal cancer and unfavourable outcome in both colon and rectal cancer. This study suggests that a single-nucleotide polymorphism of the KRAS gene (LCS-6 variant) may predict response to neoadjuvant treatment and mitigate the poor prognosis associated with KRAS mutation in locally advanced rectal cancer.

Role of Kras Status in Patients with Metastatic Colorectal Cancer Receiving First-Line Chemotherapy plus Bevacizumab: A TTD Group Cooperative Study
2012
Background: In the MACRO study, patients with metastatic colorectal cancer (mCRC) were randomised to first-line treatment with 6 cycles of capecitabine and oxaliplatin (XELOX) plus bevacizumab followed by either single-agent bevacizumab or XELOX plus bevacizumab until disease progression. An additional retrospective analysis was performed to define the prognostic value of tumour KRAS status on progression-free survival (PFS), overall survival (OS) and response rates. Methodology/Principal Findings: KRAS data (tumour KRAS status and type of mutation) were collected by questionnaire from participating centres that performed KRAS analyses. These data were then cross-referenced with efficacy da…
Effects of nicotine on spatial learning in C57BL mice
2000
In the present study, the effects of nicotine on spatial memory in C57BL/6J mice was evaluated. Mice were trained in a water maze during four daily sessions of three trials each. In the first experiment, nicotine (0.7 and 0.35 mg/kg) or saline was administered once daily for 4 days, 15 min before the start of daily training: an impairment of performance of the water maze was observed in the group treated with 0.7 mg/kg of nicotine. In the second experiment, nicotine (0.7 and 0.35 mg/kg) or saline was administered from the 5 days prior to the beginning of the task and during the 4 days of acquisition. The results indicated an improvement in the rate of learning in the 9-day nicotine treated …
KRAS and BRAF mutations in circulating tumour DNA from locally advanced rectal cancer.
2018
Abstract There are limited data on circulating, cell-free, tumour (ct)DNA analysis in locally advanced rectal cancer (LARC). Digital droplet (dd)PCR was used to investigate KRAS/BRAF mutations in ctDNA from baseline blood samples of 97 LARC patients who were treated with CAPOX followed by chemoradiotherapy, surgery and adjuvant CAPOX ± cetuximab in a randomised phase II trial. KRAS mutation in G12D, G12V or G13D was detected in the ctDNA of 43% and 35% of patients with tumours that were mutant and wild-type for these hotspot mutations, respectively, according to standard PCR-based analyses on tissue. The detection rate in the ctDNA of 10 patients with less common mutations was 50%. In 26 ca…
A translational paradigm to dtudy the rffects of uncontrollable stress in humans
2020
Theories on the aetiology of depression in humans are intimately linked to animal research on stressor controllability effects. However, explicit translations of established animal designs are lacking. In two consecutive studies, we developed a translational paradigm to study stressor controllability effects in humans. In the first study, we compared three groups of participants, one exposed to escapable stress, one yoked inescapable stress group, and a control group not exposed to stress. Although group differences indicated successful stress induction, the manipulation failed to differentiate groups according to controllability. In the second study, we employed an improved paradigm and co…
Negatively condition dependent predation cost of a positively condition dependent sexual signalling.
2006
Predation is considered as an important factor constraining the expression of sexual signals. Nevertheless, direct quantitative evidence for predation provoking significant viability costs on individuals signalling at high rates is scarce. Moreover, it is unclear whether high rate signallers are able to balance presumably increased predation costs. We examined whether a condition dependent audible sexual signal, drumming, makes Hygrolycosa rubrofasciata male spiders more prone to predation by pied flycatchers (Ficedula hypoleuca), and whether sexual signalling rate is related to escaping ability once attacked. When birds were given a choice between two spider males manipulated to drum eithe…
