[Adenoid cystic carcinoma. Presentation of three clinical cases].

Adenoid cystic carcinomas are malignant epithelial tumors that originate in body regions containing exocrine and eccrine glands. Their most common location is the salivary glands. These tumors have specific, highly individualized histopathological and clinical features. Three cases of adenoid cystic carcinoma in different sites, palate, sublingual gland, and nasal cavity, are reported. The literature is reviewed for information about the fundamental clinical, diagnostic, and therapeutic aspects of these tumors.

Tonsil and adenoid surgery for upper airway obstruction in children.

We studied the outcomes of 76 children, aged 3 to 12 years, with large tonsils and/or large adenoids who underwent surgery to relieve upper airway obstruction over a 1-year period. Following surgery, nearly all patients experienced an alleviation of all symptoms, except for enuresis. We suggest that children who have large tonsils and/or adenoids will gain substantial benefit if they are removed, even children who do not have a history of severe sleep apnea or objective evidence from polysomnography.

[Adenoid cystic carcinoma of the minor salivary glands. Our experience].

Adenoid cystic carcinoma is the most frequent malignant tumor of the minor salivary glands. It is characterized by a slow, but aggressive, clinical evolution, which tends to produce distant metastases even years after the initial surgical treatment. We present a clinical study of 19 patients with adenoid cystic carcinoma of the minor salivary glands that were treated with surgery and radiotherapy. The survival (vital) prognosis for this study declined in the third year after initial treatment, with recurrence and distant metastases occurring several years after treatment. Therefore, the clinical course of this disease requires long-term follow-up of patients.

[Adenoids in adults].

127 patients with adenoids aged 15-48 years were treated. Adenoids in the adults have some special clinical features, they frequently arise in the presense of nasal pathology (septal defects, hypertrophy of the turbinated bones), simulate nasopharyngeal tumors. Adenotomy in adults should be made in hospital. Its technique differs in some details from this operation in children.

[Adenoid cystic carcinomas of the head and neck (cylindromas)].

In the years 1958-1997 111 patients with adenoid cystic carcinoma in the head and neck of different localization were treated at the Department of Otolaryngology--Head and Neck Surgery. Majority of the tumors originated of the major salivary glands, mainly in the parotid gland (47 cases). The most common location among the tumor of the minor salivary glands was the palate (14 persons). The tumors arising from other mucous glands, most frequently has located in the maxillo-ethmoideal complex (20 cases). The authors stress diagnostic difficulties, the necessity of a proper selection of the surgical method and postoperative radiotherapy, describing the treatment results in the patients. Radial surgical procedure of the adenoid cyctic carcinoma yelds optimal local control and survival rates.

Choanal adenoid syndrome--a preliminary report.

A series of 19 patients with long-lasting nasal stenosis despite repeated treatment attempts, including, in many cases, repeated adenoidectomy, was found to have ectopic adenoid tissue inside the choanae. The choanal adenoid tissue could not be removed by curettage, only transnasally using forceps. The treatment was successful in all 19 patients. It is estimated that in at least 2% of the patients with long-lasting nasal stenosis, attention should be focused on the bottleneck of the nasopharyngeal airway represented by the choanae, primarily by fibre optic endoscopic examination.

Combined treatment of adenoid cystic carcinoma of the salivary glands.

A retrospective review of the experience of a single surgeon over a 20-year period is presented. Fifteen patients with primary adenoid cystic carcinoma of the major (6) or minor (9) salivary glands underwent combined treatment with wide local excision and radical postoperative radiotherapy. The actuarial survival is 100% at 5 years and 62% at 10 and 15 years. The disease-specific survival is 100% at 5 years and 86% at 10 and 15 years. There were no loco-regional recurrences. Wide local excision and radical postoperative radiotherapy seems to be an effective treatment for adenoid cystic carcinoma of the salivary glands.

Uncontrolled central adenoid cystic carcinoma: case report.

Central adenoid cystic carcinomas are rare malignancies that are believed to arise in ectopic salivary gland tissue within the maxilla or mandible. We describe the diagnosis and treatment of a central adenoid cystic carcinoma in a 54-year-old man, which we believe was a recurrence of an earlier growth that had not been completely excised. We also present a review of the literature.

Adenoid cystic carcinoma of Bartholin's gland: a case report.

Adenoid cystic carcinoma is an uncommon histological type of the already rare carcinoma of Bartholin's gland with 51 cases described in the literature. We present a case of a 66-year-old woman who was admitted with severe pelvic pain. In an examination under anesthesia a 10x5 cm apparently fixed mass at the left vaginal wall originating from the area of Bartholin's gland was found. and biopsy indicated carcinoma. The patient underwent wide local excision. Although clinically inoperable, the tumor did not infiltrate the bony pelvis and no evidence of metastasis was found. Pathology examination revealed adenoid cystic carcinoma of Bartholin's gland. PCR did not detect human papillomavirus DNA in the specimen. The patient has been treated with adjuvant radiotherapy, and is alive with no evidence of disease after ten months.

[A case of tracheal adenoid cystic carcinoma in a young woman].

A case of an adenoid cystic carcinoma of trachea is presented. A 30-year-old non-smoking woman with strong inspiratory dyspnea at rest was admitted to the Dept. of Pulmonary Diseases. At auscultation a respiratory murmur was more silent at right lung and stridor over trachea was heard. CT scan revealed tumor at the bifurcation of the trachea. Bronchoscopy was made and biopsy established the diagnosis: adenoid cystic carcinoma. The tumor was partially removed with rigid bronchoscope and radiotherapy was started. Clinical improvement occurred; in control CT scan tumor vanished. The trachea cancers are rare. Symptoms often mimic asthma or chronic bronchitis. Thus in every patient with chronic cough and dyspnea bronchoscopy should be made. A treatment of choice is primary resection and postoperative radiotherapy.

[The effect of protein kinase C on the invasive behavior of human salivary adenoid cystic carcinoma in vitro].

OBJECTIVE: To explore the relationship between protein kinase C (PKC) and invasion/metastasis of salivary adenoid cystic carcinoma and to explore the possibility of treatment against invasion/metastasis of the tumor cell by PKC inhibitor. METHODS: SACC-83 cell line cells were treated by endogenous PKC inhibitor BS-PKCI extracted from bovine spermatozoa and exogenous PKC inhibitor H(7), while the adhesion to basement membrane, movement (expressed by the cell numbers moving out from agarose drop and the furthest distance) and invasive capacity in vitro were observed. RESULTS: (1) The two inhibitors suppressed significantly adhesion of the tumor cell to basement membrane (P < 0.05). (2) The two inhibitors suppressed significantly movement of the tumor cells (P < 0.05). (3) The two inhibitors suppressed significantly invasive capacity of the tumor cells in vitro (P < 0.01). CONCLUSIONS: There was a close relationship between PKC and invasion/metastasis of salivary adenoid cystic carcinoma; the two PKC inhibitor suppressed significantly adhesion, movement and invasive capacity of SACC - 83 cell line cells in vitro.

Adenoid cystic carcinoma of the paranasal sinuses or nasal cavity: a 40-year review of 35 cases.

We retrospectively reviewed 35 cases of adenoid cystic carcinoma that had originated in the minor salivary glands of the paranasal sinuses or nasal cavity. All patients had been seen at two tertiary-care referral centers in western New York State between 1960 and 2000. Twenty patients had been treated with surgery and adjuvant radiotherapy, 10 patients with surgery alone, three with radiotherapy alone, and two with concurrent radiotherapy and chemotherapy. During the study, 22 patients developed recurrent disease--11 locally; three distantly; seven locally and distantly; and one locally, regionally, and distantly. At the conclusion of the study, 14 patients were alive and disease-free, and eight were alive with disease; 10 patients had died with disease, and three had died of other causes with no evidence of disease. Adenoid cystic carcinoma of the paranasal sinuses or nasal cavity is an aggressive neoplasm that results in a high incidence of both local recurrence and distant metastasis, regardless of treatment modality. Most cases are ultimately fatal, although long disease-free intervals have been observed. A combination of surgery and radiotherapy offers these patients the best chance for disease control.

[Adenoid cystic carcinoma (cylindroma) of the nasopharynx with extension into the cavernous sinus].

INTRODUCTION: The adenoid cystic carcinoma or cylindroma of the nasopharynx is a rare tumour characterised by its slow progression, high risk of local recurrence and prolonged survival, even in the locally advanced and/or metastatic forms. Treatment is pluridisciplinary. OBSERVATION: In a 30 year-old man consulting for right retroauricular pain, hypoacousia and epistaxis, diagnosis of a nasopharyngeal cylindroma was made in 1994. Treatment consisted first line surgery combined with loco-regional radiotherapy. Twenty-six months after complete remission had been obtained, a loco-regional relapse was revealed, combined with pulmonary metastases. The treatment combining radiotherapy, surgery and chemotherapy led to the stabilisation of the disease. COMMENTS: The adenoid cystic carcinoma of the nasopharynx a rare neoplasia of the head and neck, characterised by its slow progression over time, a high risk of relapse and the progression of metastases at distance. The corner stone of its therapeutic management is surgery. Radiotherapy improves the local control of the disease and chemotherapy is helpful in treating the metastatic disease.

[Analysis of 19 cases adenoid cystic carcinoma of the nasal cavity].

OBJECTIVE: To study the biological features of adenoid cystic carcinoma of the nasal cavity in order to provide a basis for its clinical treatment. METHOD: A retrospective analysis was made to 19 cases which were treated with operation combined with preoperative chemotherapy and radiation. RESULT: 5, 8, and 10 years' follow-ups conducted post treatment showed the local recurrence rates were 5.3%, 21.1%, and 31.6% respectively. CONCLUSION: Adenoid cystic carcinoma of the nasal cavity is highlighted because of high-degree local infiltration, the specific anatomy of the cavity, and the difficulty of wide-ranging surgical resection. Preoperative chemotherapy combined with radiation has the advantages of extinguishing the recessive cancerous foci, inhibiting the primary foci and lowering local recurrences and cancerous metastases. Thus it constitutes an effective way to deal with this malignancy.

[Clinical analysis of 20 cases of adenoidal hypertrophy in adult].

OBJECTIVE: To discuss the diagnosis and properly treatment to the adult adenoidal hypertrophy. METHOD: To do nasal endoscopic and pathologic exam to all the 20 symptomatic patients before conservative or operative treatment. RESULT: The results of exam under endoscope were that 8 patients were hypertrophy I, 8 hypertrophy II, 4 hypertrophy III. Pathologic exam: 7 acute and chronic inflammation, 13 chronic inflammation with hyperplasia. TREATMENT: 10 of them received conservative treatment all have negative result. 6 received traditional operation, 2 of them reoccurred within 1 year. 4 received adenoidectomy and microwave treatment under nasal endoscope, all have good result in the next 1 year. CONCLUSION: Some adults have different sizes of adenoidal hypertrophy. This hypertrophy is different with children's under the pathologic microscope. Operative treatment especially the nasal endoscopic adenoidectomy and microwave treatment is a safe and effective method.

[Expression of TGF beta 1 and TGF beta RI proteins in tissues of salivary adenoid cystic carcinoma].

OBJECTIVE: To determine the possible role of TGF beta 1 and TGF beta RI in facilitating neoplastic progression in human salivary adenoid cystic carcinoma (ACC). METHODS: The expression of TGF beta 1 and TGF beta RI protein in human salivary adenoid cystic carcinoma was detected by the streptavidin-peroxidase (S-P) immunohistochemical method, and their contents were compared with those of normal salivary gland tissues and salivary pleomorphic adenoma (PA). RESULTS: 1. TGF beta 1 and TGF beta RI proteins were expressed in most ductal epithelial cells and myo-epithelial cells, but they were not expressed in the acinar epithelial cells of any normal glands examined; 2. TGF beta 1 and TGF beta RI proteins were expressed in the duct-like arranging tumor cells and other solid proliferating tumor cells of salivary pleomorphic adenoma, and no difference of their contents existed between PA and normal salivary gland tissues (P > 0.05); 3. The contents of TGF beta 1 in ACC were significantly higher than those in normal salivary glands (P < 0.01), while the contents of TGF beta RI in ACC were significantly lower than those in normal salivary glands (P < 0.01). CONCLUSION: The abnormal expression of TGF beta 1 and TGF beta RI might play an important role in tumor genesis and the development of malignant salivary gland tumors such as ACC; the over-expression of TGF beta 1 and low-expression of TGF beta RI might involve the bad biological behavior of ACC.
