Abstract
INTRODUCTION Whereas in the adult population 5-Aminolevulinic acid (5-ALA) fluorescence guidance has been widely accepted for improving the extent of tumor resection, the application in children remains an off-label use. Even though most pediatric study protocols require a complete resection for improving outcome parameters, only few pediatric patients have been operated with fluorescence guidance, and it remains questionable, whether and which pediatric tumors show useful fluorescence. We present casuistic reports of application of 5-ALA in children collected from three different neurosurgical departments. PATIENTS AND METHODS In children with suspected malignant intracerebral tumor or recurrence, individual informed consent was obtained in each case from the parents. 5-ALA was administered according to the adult protocol, with 20 mg/kg, 2 h before induction of anesthesia. We retrospectively analyzed 18 patients (13 male, 5 female; age 3-18 years), using the intraoperative neurosurgical protocol, the postoperative MRI results, and the follow-up clinical examinations. RESULTS The use of 5-ALA fluorescence guidance proved to be safe in our group of pediatric patients. Fluorescence guidance was most useful for recurrent glioblastoma resection. Medulloblastoma tissue displayed fluorescence only inconsistently, and most pilocytic astrocytoma remained without staining. Ganglioglioma showed partial staining in the central tumor areas, without allowing the use for circumferent resection. CONCLUSION The off-label use of 5-ALA fluorescence guidance in pediatric patients appears to be most useful in recurrent high-grade gliomas. Fluorescence accumulation in other pediatric brain tumor entities is not predictable and should be evaluated in future clinical studies before being integrated into the current treatment protocols.

Abstract
There has been a long lasting debate, whether planned neck dissections after curative radio(chemo)therapy for locally advanced head and neck squamous cell carcinomas offer some benefit in tumor control or survival. We did a thorough literature research on that topic. The results of several recently published studies are described, summarized, and reviewed. Patients with residual disease in clinical or radiographic examinations (CT or MRI scans) up to 3 months after completion of radiochemotherapy profit from neck dissections. In patients with an initial or delayed clinical complete remission after completion of radiochemotherapy, a neck dissection can be safely omitted. In conclusion, there is no longer evidence for a benefit of prophylactic post-radiochemotherapy neck dissections, but strong evidence for a therapeutic post-radiochemotherapy neck dissection in this group of patients.

Abstract
The aim of this study was to correlate acute organ toxicity during preoperative radiochemotherapy with overall survival and tumor regression for patients with primarily operable esophageal carcinoma. From 1995 to 2002, 60 patients with primarily operable esophageal carcinoma were treated in a preoperative setting at our department. Thirty-three percent of the patients had International Union against Cancer (UICC)-stage II tumors, 62% had UICC-stage III tumors, and 5% had UICC-stage IVA tumors. All patients received irradiation (40 Gy at 2 Gy/fraction). Chemotherapy for all patients with adenocarcinoma and, from 2001, also for patients with squamous cell carcinoma consisted of two cycles, 5-fluorouracil and cisplatinum; between 1995 and 2001, patients with squamous cell carcinoma received three courses of chemotherapy (folinic acid, etoposide, 5-fluorouracil, and cisplatinum every 3 weeks) before and further cisplatinum and etoposide during radiotherapy. We found a significant correlation between acute organ toxicity and histopathological tumor regression, as well as overall survival. The probability to achieve tumor regression grade 1 after radiochemotherapy was nearly four times higher for patients with worsening of odynophagia than for those without an increase (odds ratio: 3.97). Patients with worsening of odynophagia had a 5-year overall-survival rate of 66% compared with 39% in patients without (P = 0.048). Our data indicate that normal tissue and tumor tissue may behave similar with respect to treatment response, as acute organ toxicity showed to be an independent prognostic marker in our patient population. The hypothesis should be further analyzed on biomolecular and clinical level in future clinical trials.

Abstract
BACKGROUND Valrubicin is a cytostatic anthracycline analogue, lacking toxicity by skin and tissue contact, and represents a new drug with potential for topical treatment of psoriasis and nonmelanoma skin cancer (NMSC); the beneficial effects have been partly explained by its antiproliferative and proapoptotic characteristics. OBJECTIVES To assess the effect of valrubicin on skin inflammation as inflammation also plays a key role in psoriasis and NMSC. METHODS The effect of topical valrubicin treatment on skin inflammation in vivo was addressed in skin inflammation mouse models, where 12-O-tetradecanoylphorbol 13-acetate was used to induce irritant contact dermatitis. An acute and a chronic model were included, to investigate the effect of valrubicin in short-term inflammation and in more persistent inflammation. Inflammation-associated ear oedema was evaluated by measuring ear thickness, infiltration of neutrophil cells, and expression of inflammatory cytokines, interleukin (IL)-1β and IL-6. RESULTS Topical valrubicin treatment effectively reduced the inflammatory response in the acute and the chronic models. CONCLUSIONS The present data document an anti-inflammatory effect of valrubicin, and may suggest an interesting new role for valrubicin in other debilitating skin diseases in which inflammation is a significant factor.

Abstract
SALL4 (sal-like protein 4) is a pluripotency transcription factor, which is highly expressed in embryonic stem (ES) cells and which is essential for mouse preimplantation development. In adult mouse organs, Sall4 mRNA is highly expressed in the testis and ovary, while there is only little or no expression in other organs. There is also a high expression of SALL4 in human testicular germ cell tumors. However, there is as yet no detailed analysis of SALL4 expression during mammalian testicular development. We analyzed SALL4 expression in ES cells, preimplantation embryos, and the developing and adult testis of a nonhuman primate (NHP) species, the common marmoset monkey (Callithrix jacchus). Immunofluorescence revealed SALL4 in the nuclei of marmoset ES cells and preimplantation embryos. Marmoset SALL4 isoform analysis in ES cells and newborn and adult testis by RT- PCR and Western blotting showed two different isoforms, SALL4-A and SALL4-B. Immunohistochemistry localized this transcription factor to the nuclei of primordial germ cells and most gonocytes in the prenatal and early postnatal marmoset testis. In the pubertal and adult testis SALL4 was present in undifferentiated spermatogonia. In the developing and adult human and mouse testis SALL4 expression mimicked the pattern in the marmoset. Adult testes from additional NHP species, the treeshrew, the cat and the dog also exhibited SALL4 in undifferentiated spermatogonia, indicating a conserved expression in the mammalian testis. Taking into account the importance of SALL4 for mouse development, we conclude that SALL4 may play an important role during mammalian germ cell development and is involved in the regulation of spermatogonial proliferation in the adult testis.

Abstract
In the last decades the chances of surviving childhood cancer have increased. Nowadays psychological and psychosocial long term side effects become more spotlighted. Especially the posttraumatic stress disorder is focused at the moment as a possible side effect of childhood cancer. Cancer as a life-threatening illness is unpredictable and associated with repeating loads, such as medical procedures or treatment. Most of the patients report anxiety, especially young children have an increased risk of making a traumatic experience while undergoing medical treatment. A psychological support before, meanwhile and after can ensure compliance as well as reducing emotional and behavioral disorders. Even preventive impact is conceivable. Therefore psychological support has become a standard in pediatric cancer treatment. The current case report of the 10 year old Tom is a practical example how to support has undergoing medical procedures. The interventions described have the aim of stabilizing the patient and reducing his anxiety and discomfort. They also show an effect on self-efficacy.

Abstract
LBA3505 Background: The German CAO/ARO/AIO-94 trial established preoperative chemoradiotherapy (CRT), surgery, and postoperative chemotherapy with 5-FU as standard treatment for locally advanced rectal cancer. With this approach local relapse rates are below 10%. The development of distant metastasis is the predominant mode of failure. Integrating more effective systemic treatment into combined modality therapy was the goal of CAO/ARO/AIO-04. Methods: Between 7/2006-2/2010, patients with rectal cancer within 12 cm from the anal verge and clinical evidence of perirectal fat or lymph node involvement were randomly assigned to receive preoperative CRT, surgery, and adjuvant chemotherapy with 5-FU according to CAO/ARO/AIO-94 (arm 1), or preoperative CRT (50.4 Gy in 28 fractions) with 5-FU (250 mg/m2/days 1-14 and 22-35) and oxaliplatin (50 mg/m2/days 1, 8, 22, 29), surgery, and 8 cycles of adjuvant chemotherapy according to modified FOLFOX6 regimen (arm 2). Disease-free survival was the primary endpoint. We present early secondary endpoints, including acute toxicity, treatment compliance, and pCR-rates. Results: 637 patients were randomly assigned to arm 1 and 628 to arm 2. Full dose preoperative RT and full dose concurrent chemotherapy was delivered in 97% and 74% of patients in both arms, respectively. Preoperative grade 3/4 toxicity occurred in 21.6% in arm 1 and in 22.9% in arm 2. The R0-resection rate was 95.4% in both arms, and abdominoperineal resections were limited to 11.9% and 12.2% in arms 1 and 2, respectively. Overall postoperative complications were not different between both arms (21.0% and 21.9%). The pCR rate (ypT0N0) was 13.1% in arm 1 and 17.6% in arm 2 (p = 0.033, Cochran-Mantel-Haenszel Chi-Squared Test without continuity correction for conditional independence of pCR rate in the two treatment arms in each stratum). Conclusions: Inclusion of oxaliplatin to 5-FU based CRT was well tolerated and associated with increased pCR-rates compared with 5-FU-CRT alone. Longer follow-up is necessary to evaluate the primary endpoint, disease-free survival.
