p53, Ki67 and cyclin D1 as prognosticators of lymph node metastases in laryngeal carcinoma.

The prognosis in patients suffering from head and neck squamous cell carcinomas depends on many factors. However, regional lymph node metastases are the most important parameter in determining the cure and survival of patients with head and neck cancers. The evaluation of cancer cell biology enables differentiation of their proliferation and tendency of metastases. Immunohistochemical examinations complement the well-established routine histological examination. The aim of this study was to evaluate the prognostic importance of the level of immunoproliferating proteins such as cyclin D1, nuclear antigen Ki67 and suppressor gene p53 for regional lymph node metastases in laryngeal carcinoma. The research was carried out on 73 patients treated for squamous cancer of the larynx in the Department of Otolaryngology University School of Medical Sciences in Poznan in the years 1994-1999. The group was comprised of 4 female and 69 male patients. Their ages ranged from 37 to 79 years, with a mean of 59 years. Clinical data included sex, age, localization and local and regional extent of the tumor, presence or lack of distant metastases, treatment, histological examination as well as immunohistochemical evaluation of suppressor gene p53, proliferative proteins Ki67 and cyclin D1. No statistically significant correlation was found between staining intensity of suppressor gene p53, cyclin D1 and the degree of local advancement (T). There was no correlation between the level of immunoproliferative markers and regional lymph node metastases. Statistically significant correlation was found between T stage and staining for Ki67 (P=0.017) as well as between cyclin D1 level and Ki67 (P<0.05). In conclusion, (1) no significant correlation was found between Ki67 and cyclin D1, p53 and TNM classification; (2) lack of correlation was confirmed between N+, p53, Ki67, cyclin D1 and Jacobsson classification; (3) the degree of histological grading correlated, however, with Jacobsson classification and cyclin D1 expression.

[Laser cordectomy: treatment of precancerous stages of the larynx]. / Chordektomia laserowa w stanach przedrakowych krtani.

UNLABELLED: Diagnostics and treatments of precancerous states of cancer of larynx will demand in select chances the multistages treatment AIM: In work one priced radicality and efficiencies of treatment of precancerous stages of larynx with method of carbone dioxide laser cordectomy. The retrospective examination was executed of years 1991-2000 imicrosurgical interventions of larynx--in talked over period one executed 308 of surgical interventions with use of laser CO2, in number this 41 of interventions were partial laser cordectomies in stages with precancerous changes on the vocal cords. In chances of extensive precancerous changes of vocal cords in sorted chances not one should limit oneself to receiving of specimens from several localization, but change to remove in wholes. Permits this on obtainment radicality of intervention with possibility of obtainment the large material to histopathological investigations.

[Metastasis of papillary thyroid carcinoma resembling the cervical lateral cyst]. / Przerzut raka brodawkowatego tarczycy imitujacy torbiel boczna szyi.

Cystic neck mass, enlarging for many years, as the first symptom of occult thyroid carcinoma was presented. On the basis of clinical and ultrasonographical examination the initial diagnosis was made: bronchiogenic neck cyst. The metastases of papillary carcinoma of thyroid gland were recognized in histological examination. The patient was admitted for surgical treatment.

[The value of endoscopic ultrasound examination for tongue neoplasms]. / Wartosc badania ultrasonograficznego z uzyciem glowicy endoskopowej w guzach jezyka.

The aim of the paper was to assess the value of endoral ultrasound in tongue tumors diagnostics. It was performed by the evaluation of the tumor advancement and its comparison with palpation, assessment of neoplastic tissue infiltration, detection of satellite foci surrounding the main tumor mass. Endoral ultrasound vs transcutaneous ultrasound was compared. Follow-up by means of transoral ultrasound was applied. The limitations of the method were presented. 65 patients with tongue tumors, treated in ENT Department K. Marcinkowski University School of Medical Sciences between 1995-1999 were under study. 9 patients with suspicion of local recurrence were included to the examined group. Not able value of the method was proved. In 81.5% of cases the method occurred to be much more precise than palpation and revealed the bigger dimension of the tumor then stated clinically. The satellite foci and small lesions, not possible to be detect by means of transcutaneous ultrasound, were find out and thanks to it treated radically. This method allows to differentiate the scarred and neoplastic tissue, especially in patients with clinical suspicion of relapse. The limitations of the method: trismus, big extension of the lesion, surface bleeding and gag reflex are to be listed.

[Craniofacial bone dysplasia]. / Osteodysplazja twarzoczaszki.

The case of fibrous dysplasia localised in the maxilla in 7 years old girl was described. Attention was paid to etiology, symptoms and treatment. The differential diagnosis was discussed.

[Breast carcinoma metastasis to paranasal sinuses]. / Przerzut raka sutka do zatok przynosowych.

The presented case is breast cancer metastatic into the paranasal sinuses. Accompanied symptoms suggested thrombosis of cavernosus sinus with very fast growing eye and neurological symptoms caused by metastases to brain tissue. Breast cancer metastatic into the paranasal sinuses is extremely rare and usually ends with death, as it is a result of neoplastic dissemination and does not react to systemic treatment. This type of neoplasm was for the first time presented in literature by Robin in 1938. Until 1994 nine cases of patients suffering from this type of neoplasm have been described. All of them died.

[Endoscopic ultrasound probe applications for diagnosis of the oral cavity and throat tumors]. / Zastosowanie glowicy endoskopowej w diagnostyce ultrasonograficznej Guzów jamy ustnej i gardla.

Assessment of neoplastic lesions situated inside palatinal tonsils and tongue may cause a lot of difficulties. Bringing into practice diagnostic tools such as: transcutaneous ultrasound, CT, MRI have met numerous limitations and obstacles. Apart from restrictions set by anatomical borders, other drawbacks of methods mentioned above are: high cost of single examination, expensive equipment and difficulties of access. In this paper the results of examination of 20 tongue tumors and 23 tonsil tumors carried out by means of endoral ultrasound are presented. Endoral ultrasound provided evaluation of size, localisation, extension and delimitation of and detect small nodules satellite to the predominant tumor mass. Evaluation of lesion echostructure enables to differentiate the tumor nature and advises to plan other diagnostic procedures.
