NLS-diagnostic Methods Of Meta Hunter And The Diagnostics Of Nasopharynx Cancer

Problems in modern diagnostics of nasopharynx cancer (NPC) are pressing in the present time, it is proven by the fact that in 70% – 80% of patients treatment starts only at III-IV stages of disease, when average period of patients medical examination is 7 months before final diagnosis is identified.

Reasons of late diagnostics of nasopharynx cancer are: prolonged asymptomatic disease course, anatomico-topographic peculiarities of nasopharynx structure, imperfection of traditional widely used diagnostic techniques, difficulties in interpretation of tumorous and non-tumorous pathology visual pictures, low oncological vigilance of general therapists.

For the last decades NLS-diagnostic methods of Meta hunter became widely spread in combined examination of patients; they demonstrate great diagnostic value at various diseases of digestive tract and respiratory organs. 3D NLS-graphy of upper respiratory tracts as diagnostic technique was developed last of all – its development was started by the Institute of Practical Psychophysics in 2006. In the future this examination method may be widely used in diagnostics of various nasopharynx pathologies and differential diagnostics of tumors of various geneses.

3D NLS-graphy allows therapists to visualize primary tumor, evaluate it spreading to pharynx walls, identify form of growth and detect genesis and character of neoplasm on the basis of resonance-entropy analysis (REA). Introduction of 3D NLS-graphy of upper respiratory tract into practical oncology made possible to develop and fulfill practical application of virtual microscopic researches with REA at the same time with routine histological examination. It extends significantly potentials of NLS-diagnostics, has an advantage over existing morphological methods of examination and allows to increase accuracy of diagnostics.

Nasopharynx neoplasms are characterized by variety of morphological forms, differing in their clinical course, histogenesis, applied methods of treatment and prognosis.

NPC is a combined group of tumors and there are many various morphological classifications with variety of used terms for it. Nowadays the most convenient in practical meaning is considered to be Micheau classification:
1. Non-differentiated cancer of nasopharyngeal type (variants: Schminke, Regaud, spindle-cell).
2. Epidermoid cancer (highly-, moderately- and lowdifferentiated ones).
3. Adenocarcinoma.
4. Cystadenocarcinoma.
5. Malignant mucoepidermoid tumor.
6. Others.
