Meta-Analysis of the Prognostic Significance of Perinodal Spread in HNSCC Patients
Dünne AA, Müller HH, Eisele DE, Kessel K, Moll P, Werner JA
Eur. J. Cancer (in press)
Study methodology allowed enrollment of only 9 studies of 115 published papers
Excluded studies lacked regarding primary tumor location, number and location of lymph node metastases, values on five-year survival, or adequate follow-up data
Results:Perinodal spread is a doubling risk factor that reduces the 5-year-survival by univariate analysis
Conclusion: Creation of international standards for assessment of micro- or macroscopic perinodal spread is important. This challenge should be approached by carefully designed multi-centre studies
Meta-Analysis on the Significance of Matrix Metalloproteinases for Nodal Disease in Head and Neck Squamous Cell Carcinoma
S. Wiegand, A.A. Dünne, H.H. Müller, R. Mandic, P. Barth, R.K. Davis, J.A. Werner
Cancer 104: 94-100 (2005)
Problem: Heterogenity of data collection, immuno-histochemical staining and statistical methods
14 studies with 710 patients for 5 different MMPs (MMP-1, -2, -3, -9, -14) could be included into Meta-Analysis
Results: MMP-2, -3, -14 were found to possibly play a role in the metastatic behaviour of HNSCC tumors
Conclusion: As a first step, standardization of immuno-histochemical staining procedures and evaluation protocols is required. These are the prerequisites to achieve comparable results for further evaluation.
in Head and Neck Cancer
=> Extirpation of only one SN (SN1) is not representative!
=> Lymphatic mapping with detection of SN 1-3 confirms concept of SND with removal of the main metastatic level.
=> Shall three tracer accumulating lymph nodes be extirpated regularly or is it a question of further limiting selective ND (e.g. SND II-III or IIA-III)?

Sentinel node biopsy in squamous cell cancer of the oral cavity and oral pharynx: a diagnostic meta-analysis.Head Neck. 2005 Sep;27(9):739-47.
Systematic review and diagnostic meta-analysis of published literature regarding until December 2003.
Total of 301 patients with oral cavity primary tumors and 46 patients with oropharyngeal primary tumors from 19 articles were included for the meta-analysis.
Quality of injection and thus experience of the examiner plays an important role for the exactness of this technique
Complex architecture and distribution of lymph vessels in the head and neck lead to a high risk of possible pitfalls
B-mode sonography plus FNA (van d. Brekel) has the same specificity and sensitivity, depending on the examiner, however, IT IS NON-INVASIVE

Extent of surgical intervention in case of N0 neck in head and neck cancer patients – an analysis of data collection of 39 hospitals
Dünne A.A., Folz B.J., Kuropkat C., Werner J.A.
Eur. Arch. Otorhinolaryngol. 261: 295-303 (2004)
Standardized questionnaire: 52 year-old male patient, moderately differentiated squamous cell carcinoma (G2), no lymphangiosis carcinomatosa, N0 neck according to imaging
Results: There is no unique treatment concept of the surgical neck treatment in Germany.
Conclusion: Necessity to develop stage-associated treatment concepts of the cervical lymphatic drainage.
Presence of malignant tumor cells in persistent neck disease after radiotherapy
Stenson KM et al. (2000) Arch Otolaryngol Head Neck Surg 126:950-956
Neck dissection for patients with N2 or greater neck disease after CRT is necessary to eradicate residual disease. The complication rate of SND after CRT with hyperfractionated radiotherapy is low. SNDs are technically feasible when performed within the "window" between the acute and chronic CRT injury (4-12 weeks).

A phase III placebo-controlled study in advanced head and neck cancer using intratumoural cisplatin/epinephrine gel
Werner J.A., Kehrl W., Pluzanska A., Arndt O., Lavery KM, Glaholm J., Dietz A., Dykhoff G., Maune S., Stewart M.E., Orenberg E.K., Leavitt R.D.
Br. J. Cancer 87: 938-944 (2002)
Intratumoral injection of cisplatin/epinephrine gel: 14/57 patients (25%) tumor volume reduction (16% complete, 9% partial regression), vs. 3% regression under placebo control (p=0.007)
Side effect: Volume reduction of neighbouring lymph nodes
Possibility of drug targeting utilizing CDDP conjugated block copolymer tracking systems for translymphatic treatment of draining lymph nodes
Block copolymer carrier systems for translymphatic chemotherapy of lymph node metastases
Dünne A.A., *Börner H.G., Schlaad H., Kukula H., Werner J.A., Antonietti M.
Most effective application of high cargo-load CDDP tracking system (48 wt.% CDDP) curing 90% of animals. Systems containing 1 or 10 wt.% of CDDP were less effective but still cured 50% of the animals.
Systems contained 0.25-0.003 mg/kg per body weight CDDP compared to 1ml/kg per body weight as usually used for curative intravenous administration
Side effect: No severe systemic and local side effects during therapy and follow-up phase, but mild adverse effects in all animals (therapy groups): local hair loss after 7-12 days accompanied by mild, local inflammation after 10-14 days
Next step:Design of PEO-b-polypeptides with advanced functions, such as programmed carrier degradation or specific liberation of reporter molecules after delivery of the drug load.
BMBF BIO-DISC: Guided local and regional pharmacotherapy utilizing an external magnetic field and shock waves (FKZ 0313674)
External magnetic field concentrates ferrofluide particles in lymph nodes, followed by application of extern shock waves to unhinge the chemo-therapeutic agent from its linkage, which results in an increase of local effectiveness

Future Concept ?
Radioimmunodetection and Immuno-PET
G A van Dongen, Amsterdam
Controversy concerning the optimized management of the neck must be aimed a subgroup definition of high risk patients by virtue of individual risk profils in order to reduce the rate of unnecessary surgical or radiotherapeutical interventions.
For this purpose, histological and/or molecular markers must be detected which allow high risk patients to be identified on the basis of the primary tumor who might then benefit from a surgical or radiotherapeutical procedure.
