[Treatment results of patients with adenoid cystic carcinoma in the Otolaryngology Department at the University School of Medical Sciences in Poznań between 1958-1999].

In the years 1958-1999 the ENT Department at the University School of Medical Sciences in Poznań treated 125 patients suffering from adenoid cystic carcinoma located in the head and neck area. The aim of this study was to assess treatment results over a span of 41 years. The cases treated included 68 women and 57 men. The highest incidence of the disease was observed in men in their 70's--16 cases and women in their 50's--19 cases. In a majority of cases, the cancer started in major salivary glands, specifically parotid--51, submandibular--11, sublingual--4. Other places included minor salivary glands located in the palate--15, cheek--8, oral cavity--5 and tongue--4. Other glands affected by the tumor were those in the ethmoidomaxillary area--23. The treatment of choice was surgery with subsequent radiation. All patients were subjected to surgical treatment, 89 of them being subsequently radiated. Local recidivation was observed in 12 patients (i.e. 10%), metastases to neighbouring lymph nodes in 9 patients (i.e. 7%). Distant metastases affected the lungs--4 cases, liver--1 and bone--1.

[Intracranial complications of sinusitis in the material of the Otolaryngology Department, K. Marcinkowski University of Medical Sciences in Poznań in the years 1964-1999].

In the period of 35 years 25 patients with intracranial complications of paranasal sinusitis were treated in the Department of Otolaryngology of the Karol Marcinkowski University School of Medical Sciences in Poznań. In the past 15 years the number of complications decreased annually by half. Intracranial sinusal complications were more frequently present in young men. In 25 patients abscesses of the frontal lobe and epidural abscesses were most often diagnosed. Surgical treatment was carried out in each case when the inflammation process spread into the bony parts or into intracranial space. The method of choice in treatment of frontal lobe abscess and subdural abscesses is elimination of sinuses inflammatory foci with a simultaneous evacuation of the abscess by puncturing of the abscess and gradual exchange of its content into antibiotic solution. Intensive antibiotic therapy was carried out for the period of 4 weeks. Mortality rate in our material concerned patients with the brain frontal lobe abscesses and amounted to 12%. In the last 15 years we succeeded to treat all 17 patients.

[Oral cavity and oropharyngeal carcinomas in the materials of the University of Medical Science, ENT Department, in Poznan, in years 1980-1999].

624 patients with malignant neoplasms of the mouth and the oropharynx treated in the ENT Department K. Marcinkowski University of Medical Sciences in Poznań between 1980 and 1999 were analysed. Since the middle of the 90-ies a rapid increase of neoplasms incidence of this location has been observed. The most numerous group were tumours of the palatine tonsil (34.8%), tongue (32.5%), floor of the mouth (5.9%), soft palate (5.3%). Advanced neoplasms which encompassed the tongue, oropharynx, mouth floor base was observed in 134 patients (21.5%). The precise definition of their site of origin primary location was not possible to establish. In the analysed group males were dominating. Heavy smoker and alcohol-abuse constitute the majority of risk-factor patients. Poor dental status and mouth hygiene in this population was observed. In the histological examination squamous cell carcinoma was a dominating. Prognosis in patients with malignant neoplasms of the palatine tonsil were better in comparison with tongue cancer.

[Comparison of DNA adducts between oral, pharyngeal and larynx cancer].

The results concerning examination of DNA adducts in oral (23 patients), pharyngeal (23 patients) and larynx cancer (10 patients) subjects are presented. DNA adduct levels were compared in respect to anatomical structure (primary tumour location), number of cigarettes smoked, TNM stage, and age of patients. DNA was isolated from removed tissue (tumour and non-tumour surrounding tissue) using detergent/phenol extraction. 32P-postlabelling assay including nuclease P1-enhancement modification was applied. Aromatic DNA adducts were found in all studied tissues. Total DNA adduct levels (tumour and non-tumour tissues) was lowest in larynx cancer, higher in oral cancer and highest in pharyngeal cancer. There were no influence of age into formation of DNA adducts. The higher level of DNA adducts was found in tumour tissue of oral cancer in the group of smokers with metastasis into lymph nodes.

Analysis of aromatic DNA adducts in laryngeal biopsies.

Epidemiological studies have confirmed the correlation between tobacco smoking, environmental pollution and the incidence of cancers of the respiratory tract. The occurrence of laryngeal cancer in Poland is relatively high compared to other European countries. Since 1969 the mortality related to larynx cancer appears to be increasing. Tobacco smoke contains an abundance of such carcinogenic compounds as polycyclic aromatic hydrocarbons (PAH), aromatic amines and N-nitrosoamines, which can react with DNA and form adducts. We analyzed aromatic DNA adducts in laryngeal tissues from patients with primary laryngeal, which was confirmed histopathologically to be squamous cell carcinoma. The group consisted of 33 patients (5 women and 28 men). Total laryngectomy was performed in patients. A detergentphenol method was used for DNA isolation. Aromatic DNA adducts were analyzed by a 32P-postlabelling technique with butanol extraction and high performance liquid chromatography. The presence of aromatic DNA adducts was demonstrated in all tissues. Large interindividual differences of DNA adduct levels were seen in each tissue studied. There was a higher mean level of DNA adducts in interarytenoid area non-tumors (51.96/10(8) +/- 91.71 NN) than in non-tumor tissue elsewhere (46.91/10(8) +/- 46.36 NN) and tumor tissue (43.52/10(8) +/- 45.88 NN). Adduct levels were correlated with age, sex, cigarette smoking and TNM stage.

[Reconstructive surgery in larynx cancer].

Subtotal laryngectomies with larynx reconstruction are an acceptable alternative to the total laryngectomy in T2, T3 larynx cancer treatment. One procedure resection and reconstruction allow for radical oncological treatment with simultaneous preservation of air passage continuity and the function of the neolarynx. In the years 1988-1997 in ENT Dept. of Karol Marcinkowski University of Medical Sciences 38 subtotal laryngectomies with larynx reconstruction were performed. They were: 34 supracricoid laryngectomies with cricohyoidopexy, 2 with epiglotohyoidopexy and 3 supraglotic laryngectomies with reconstruction. The basic criterion of the evaluation of such procedures effectiveness was their oncological radicality. The follow-up period ranged from 2 to 9 years. Local relapse was observed in none of the cases, nodal relapse was started in 2 patients. Another aspect taken into consideration was the function of the neolarynx. In 3 cases two or three laser procedures were performed because of neolarynx lumen structure which were followed by T-dren plasty. In 10 patients temporary swallowing difficulties, especially liquids, were observed in the first three month. Gastrostomy was performed in one case. The authors discuss indications to this type of surgery, operation technique, oncological and functional results. Spirometry results and voice analyses after larynx resection and reconstruction in these patients are presented.

[Value of intraoral ultrasonography in diagnosis of tonsillar tumors].

UNLABELLED: Aim of the study was to establish clinical utility of intraoral ultrasonography in diagnosis of tonsillar tumours in respect to its magnitude, location, histological structure, presence of satellite lesions and furthermore compare results obtained by endoral to transcutaneous ultrasonography. 64 patients with tonsillar tumour entered the study. Endoral ultrasonography was performed by probe UST-937 Convex 5 MHz. CONCLUSION: Endoral ultrasonography is very efficient in exact tumour localisation and correlation between endoral ultrasonography and intraoperative assessment of T tumor is statistically significant. Ultrasonography is sensitive in recognition of satellite lesions. In the case of planoepithelial cancer, malignant lymphoma and inflammatory process very characteristic features of tumor can be described. Endoral ultrasonography is better then transcutaneous in tonsillar tumours diagnosis.

[Analysis of aromatic DNA adducts in oral cavity and pharyngeal cancer].

An exposure to tobacco smoke carcinogens is followed by an interaction of chemical carcinogens with DNA molecule resulted by the formation of carcinogen: DNA adducts. The study subjects were 40 oral and pharyngeal cancer patients with primary tumours diagnosed as squamous cell carcinoma. The biological samples purchased for analysis included tumour biopsy, the surrounding tissue (histopathologically recognised as non-malignant) and peripheral blood leucocytes. For DNA adducts analysis first DNA was isolated using phenol detergent extraction followed by 32P-postlabelling assay including P1 nuclease enhancement. Aromatic DNA adducts were found in all studied tissues. The average levels of DNA adducts in tumour and non-tumour tissues were found higher than in leucocytes. Biopsies from pharynx contained higher levels of DNA adducts than from oral cavities. Confounding effect of tobacco smoking and alcohol consumption on DNA adducts level was observed but it has not reached statistical significance. Formation of DNA adducts was not depended on such factors as patients age, sex, pulmonary tuberculosis, cancer progression (TNM), environmental pollution and mechanical irritation.

[Primary malignant melanoma of the larynx].

Primary malignant melanoma of the larynx is very rare. The case of larynx malignant melanoma in 71-years old men is presented. Hoarseness was the main complaint that encouraged the patient to visit a doctor. The patient was heavy smoker, he had been smoking 40 cigarettes for the last 50 years. He used to drink about 200 ml of pure alcohol per day. In the direct laryngoscopy gluish had cyanotic tumor, extending to the true vocal cord, ventricle, ventricle fold and subglottic space was seen. Enlarged cervical lymph nodes, laterally to the main vessels were found both in palpation and in US examination. Total laryngectomy and neck dissection was performed. The histological examination of surgical specimen revealed; Malignant melanoma. Metastases in the lymph nodes. Neoplastic infiltration of the nodal capsule. The patient was admitted to the complementary radiotherapy. At the moment the follow up in outpatient. The article contains the review of literature concerning the diagnosis, treatment and prognosis in cases of laryngeal malignant melanoma.

[Practical significance of the 6 level neck classification in cancers of the aerodigestive tract].

Lymph node metastases are one of the main reasons of treatment failure in head and neck cancer. Thus, knowledge of lymphatic system anatomy and routs of spreading the metastases in particular primary tumor localisation is of great practical importance. Typical sites of neck metastases in larynx and tonsil cancer were presented. The neck lymphatic system classification according to American Academy of Otolaryngology--Head and Neck Surgery from 1991 was used. The most often site of metastases in larynx cancer was the II and III level, in tongue and floor of mouth cancer--level I and II and in nasopharynx malignancies--level II and V respectively. Knowledge of the neck regions with elevated risk of harbouring metastases was important not only during the surgery but as well before planning of the selective or elective radiotherapy.
