Middle meatus nasal cytology compared to inferior turbinate cytology in non allergic rhinitis.

PURPOSE: Non allergic rhinitis (NAR) comprises different clinical definitions and phenotypes, including non inflammatory non allergic (NINAR) and cellular inflammatory forms. Nasal cytology, usually performed by scraping the inferior turbinate, is a non invasive, cheap and point-of-care tool to distinguish among the different NAR phenotypes, but still a relevant proportion of patients evaluated by nasal cytology receive a non precise definition of NAR phenotype. We hypothesize that collecting nasal cytology samples from middle meatus could increase the diagnostic accuracy. METHODS: Consecutive patients with chronic rhinitis without evidence of allergic sensitization were assessed for nasal cytology by means of scraping both the inferior turbinate and the middle meatus (lateral-inferior wall of the middle turbinate). RESULTS: 107 consecutive patients with NAR were enrolled in the study. According to inferior turbinate cytology, 42.1% were defined as affected by NINAR, 2.8% by bacterial rhinitis, 10.3% by non allergic rhinitis with eosinophils (NARES), 15.0% non allergic rhinitis with neutrophils (NARNE), 19.6% non allergic rhinitis with mast-cells (NARMA) and 10.3% non allergic rhinitis with eosinophils and mast-cells (NARESMA). Middle meatus cytology was in accordance with inferior turbinate cytology in only 37.6% of cases. Eosinophils and mast-cells were detectable more frequently in middle meatus samples (49.5% vs 19.6%, p < 0.01, 59.8% vs 29.9%, p < 0.01, respectively). 93.3% of NINAR patients received an inflammatory NAR phenotype at middle meatus cytology: 26.7% NARES, 24.4% NARNE, 31.1% NARMA and 11.1% NARESMA. CONCLUSION: Middle meatus cytology is more reliable than inferior turbinate cytology in phenotyping patients with NAR. Our study strengthen that nasal cytology should be implemented in clinical practice collecting samples at the middle meatus level.

Turbinate surgery: which rhinitis are most at risk.

BACKGROUND AND AIM: Allergic rhinitis (AR) and non-allergic rhinitis (NAR) belong to field of vasomotor rhinitis, characterized by nasal hyper-reactivity. Since AR and NAR are two separate nosological entities, these rhinopaties can coexist in the same patient in up to 15-20% of cases. Overlapped rhinitis (ORs) are associated with intense and persistent symptoms and are often misdiagnosed. Typically, when medical treatment fails, patients undergo turbinate surgery. We evaluated which rhinopaties are most at risk of undergoing turbinate surgery and established the percentage of ORs.  Methods: The study included 120 patients undergoing turbinate surgery for turbinate hypertrophy. Anterior rhinoscopy, nasal endoscopy, nasal cytology, skin prick tests (SPT) and/or specific IgE serum assays (CAP-RAST) were performed preoperative on all patients. RESULTS: Among patients with indication for turbinate surgery, 75% suffered from AR, whereas 25% of them had NAR. On closer analysis, only 7 (8%) of allergic patients presented a "pure" allergy.  NAR with eosinophils and mast cells (NARESMA) represented the most common type of superimposed rhinitis (62.5%), while NAR with mast cells (NARMA) and with eosinophils (NARES) represented 25% and 12.5% of the superimposed forms, respectively. CONCLUSION: Most of the patients undergoing turbinate surgery actually have complex forms of rhinitis. The non-allergic component of ORs often causes therapeutic failure. NARESMAs overlapping ARs are at most risk of undergoing turbinate surgery. Correctly framing a rhino-allergological patient is essential in order to guarantee the most adequate treatment. Hence the importance of introducing in clinical practice investigations, including allergy tests and nasal cytology.

Chronic rhinosinusitis with nasal polyps: how to identify eligible patients for biologics in clinical practice.

Objective: This study compared three severity measures for chronic rhinosinusitis with nasal polyps (CRSwNP). The outcome was to identify patients who are eligible for biological therapy. Methods: 330 adult patients with CRSwNP were examined. Nasal polyp score (NPS), sinonasal outcome test (SNOT-22) and clinical-cytological grading (CCG) were compared. Clinical history, past surgery and asthma control test were also considered. Results: Only 45 (13.6%) patients had a contextual positivity to the three severity measures. The concordance among tests was slight/fair. Patients with severe disease (all tests positive) had more impaired parameters. The mixed cytotype (OR = 4.07), nasal obstruction (OR = 10.06), post-nasal drip (OR = 1.98), embarrassment (OR = 2.53) and difficulty falling asleep (OR = 1.92) were significantly associated with severe CRSwNP. Conclusions: To identify candidates for biological therapy, the contextual use of NPS, SNOT-22 and CCG is preferable. In this way, global assessment of CRSwNP, including morphology, inflammation, comorbidity, symptoms and quality of life is possible.

PEComa of the nasal cavity with worrisome histologic features and benign behavior: a case report.

OBJECTIVES: PEComas (perivascular epithelioid cell tumors) are a family of neoplastic lesions that share overlapping ultrastructure and morphological and immunohistochemical appearance and include angiomyolipoma, lymphangioleiomyomatosis, and clear cell "sugar" tumor of the lung, as well as similar tumors that occur in a variety of visceral, cutaneous, and soft tissue sites throughout the body. METHODS: A 40-year-old woman came to medical attention because of epistaxis and because of unilateral nasal obstruction of 3 months' duration. Endoscopic examination revealed a well-demarcated exophytic lesion attached to the anterior portion of the middle turbinate. RESULTS: The lesion was superficially located, and therefore amenable to complete surgical excision. Seven years after surgery, the patient is alive and well, without evidence of local recurrence or metastastic disease. Based on morphological and immunohistochemical appearance, a diagnosis of PEComa with worrisome histologic features was rendered. CONCLUSIONS: In the present study, we describe a PEComa that occurred in the nasal cavity and discuss the behavior of this entity. The importance of recognizing this disease will ensure its consideration in the differential diagnosis of tumors of the head that have similar morphological features. The histogenesis of PEComa still remains elusive, and collection of additional cases with a prolonged follow-up will be important in accurately determining the behavior of these distinctive tumors.

Ki-67 proliferation rate as a prognostic marker in major salivary gland carcinomas.

OBJECTIVES: The study was performed to evaluate the prognostic relevance of cell proliferation associated with Ki-67/ Mib-1 immunostaining in malignant tumors of the major salivary glands. METHODS: Cell proliferation was evaluated by Mib-1 antibody against Ki-67 antigen in 41 patients with cancer of the parotid or submandibular glands, including 14 acinic cell carcinomas, 12 ductal carcinomas, 7 mucoepidermoid carcinomas, 5 carcinomas ex pleomorphic adenoma, 1 adenoid cystic carcinoma, 1 undifferentiated carcinoma, and 1 polymorphous low-grade adenocarcinoma. RESULTS: Patients with Ki-67 values of more than 15% and those with Ki-67 values of 15% or less differed both in disease-free survival (p < 0.001) and in overall survival (p < 0.001). We evaluated the association between Ki-67 and time to recurrence in correlation to age, sex, ductal histotype, and N stage; the Cox regression model was significant (p = 0.013). In the group of patients with T1 and T2 cancers, those with Ki-67 values of 15% or less had better survival rates than did those with Ki-67 values of more than 15% (p = 0.004). In the group of patients with N0 cancers, those with Ki-67 values of 15% or less had a better survival than did those with Ki-67 values of more than 15% (p < 0.001). CONCLUSIONS: To our knowledge, this is the first study to stratify different risk classes in early T1-T2 or N0 malignant tumors of the major salivary glands that identified aggressive lesions with elevated Ki-67 expression at an initial stage.

Cervical bronchogenic cyst: asymptomatic neck mass in an adult male.

Bronchogenic cysts are rare congenital malformations of ventral foregut development. They are usually located in the mediastinum and intrapulmonary regions. Localization in the cervical area is unusual and the majority of cases reported have been found in the pediatric population: the literature reports few cases in adults. We describe a 57-year-old male who presented an asymptomatic right lateral neck mass. Diagnostic studies included chest X-ray, pharyngo-esophagus double-contrast X-ray, computed tomography (CT), and bronchoscopy. The mass was excised through a transverse right cervical skin incision. The right lateral neck mass of the patient was identified as a bronchogenic cyst. The embryology, the presentation, the pathological and radiological evaluation, treatment of the cyst and a review of the English literature are reported in this paper. Cervical bronchogenic cysts are usually diagnosed in the pediatric population; these lesions are rare in adults. We suggest that the clinical observation of an asymptomatic lateral neck mass in an adult should include the possibility of a bronchogenic cyst in the differential diagnosis. Surgical excision is the elective treatment for this tumor, in order to prevent complications including infection, compression symptoms, malignant transformation, and the rare but fatal air embolism.

Supracricoid laryngectomies: long-term oncological and functional results.

CONCLUSIONS: Our results confirm that supracricoid laryngectomies (SL) are reliable techniques for glottosupraglottic tumors, even for selected T3 and T4 cases, if the indications are correct. These surgical techniques allow a good quality of life with the preservation of the larynx. OBJECTIVE: SL with cricohyoidoepiglottopexy (CHEP) and cricohyoidopexy (CHP) have been popular over the last 20 years for the treatment of the glottic and/or supraglottic squamous cell carcinoma due to demonstrated good oncological and functional results. We report our experience with these techniques, with special focus on long-term oncological and functional results. PATIENTS AND METHODS: We retrospectively reviewed 206 patients who had undergone SL with CHEP or CHP technique between 1987 and 1998 for glottosupraglottic squamous cell carcinoma in our department. The long-term results for 206 patients with T1-T4 laryngeal carcinomas treated with SL are reported: 90.8% CHEP and 9.2% CHP. The mean follow-up was 62 months. RESULTS: Oncological results: the 5-year actuarial disease-free survival was 85%; the 5-year determinate actuarial survival was 88.3%. Functional results: organ preservation rate was 97%. Phonation was assessed according to the GRBAS scale.

Does unnecessary elective neck treatment affect the prognosis of N0 laryngeal cancer patients?

OBJECTIVE: Among detractors of elective neck (N0) treatments, most suggest that lymphadenectomy removes a barrier to the spread of disease with deleterious immunologic consequences. To test this hypothesis we performed a retrospective comparison of the survival results of N0 laryngeal cancer patients who received unnecessary elective neck treatments (N0-) and those of N0 patients subjected to close and regular follow-up. MATERIAL AND METHODS: A retrospective chart review of 749 N0 laryngeal cancer patients treated at the Institute of Otolaryngology-Head and Neck Surgery, University of Florence between January 1980 and January 1993 was performed. Of these, 245 (33%) received elective neck dissection (ED), while the remaining 504 (67%) N0 patients were subjected to close and regular follow-up (wait-and-see policy; WS). RESULTS: Of the 245 ED patients, 43 (17.5%) showed an occult neck disease, while of the 504 WS subjects, 83 (17%) developed neck metastases during follow-up. Moreover, 15 ED patients subsequently experienced a contralateral occult failure despite a unilateral negative neck specimen (N0-). Thus, ultimately 187 ED (164 of whom were treated unilaterally and 23 bilaterally) and 421 WS patients were used for survival analysis. No differences in terms of postoperative complications, local or distant failure or disease-free or overall actuarial survival were found between the two groups analyzed. CONCLUSIONS: These data indicate that unilateral or bilateral removal of cervical lymphatics in the absence of histologically proven lymph node metastases does not negatively affect the prognosis of N0 laryngeal cancer patients who were overtreated to the neck.

Epidermal growth factor receptor and p53 expression in T1-T2 glottic cancer involving the anterior or posterior commissure.

OBJECTIVE: We surveyed retrospectively the expression of epidermal growth factor receptor (EGFR) and p53 in cases of T1-T2 glottis cancer involving the anterior (AC) or posterior commissure (PC) subsites to check for differences possibly explaining the different prognoses of cancer at these subsites. MATERIAL AND METHODS: Between 1970 and 1995, 15 patients with T1-T2 primary glottis cancer involving the PC, either partly or entirely, were treated. Thirty more cases were selected among 184 patients treated during the same time period for AC glottis cancer, to match the former cases with regard to age, sex, tumor stage, smoking habits and alcohol consumption. RESULTS: A significantly higher frequency of EGFR expression occurred in PC than in AC cancer. CONCLUSION: These results, and the anatomy of the PC subsite, may explain the more frequent recurrence of T1-T2 PC compared to T1-T2 AC cancer and why radiotherapy achieves worse results in T1-T2 PC cancer than in AC cancer of comparable T grade.

Risk factors and prognosis of anterior commissure versus posterior commissure T1-T2 glottic cancer.

For better understanding of the causation and behavior of T1-T2 commissural glottic laryngeal tumors, we retrospectively analyzed risk factors and outcome related to T class and type of therapy for tumors involving the anterior (184 cases) or the posterior (60 cases) commissure. The patients' smoking habits and alcohol consumption were similar, regardless of involved subsite. The disease-free interval was longer after surgery than after radiotherapy. The survival rates after recovery upon relapse were similar among subsites, T classes, and types of therapy. In anterior commissure tumors, the larynx remained preserved more frequently after partial laryngeal resection than after radiotherapy, and was more frequently preserved the lower the T class. In posterior commissure tumors, larynx preservation was less frequent and apparently independent of type of therapy or T class. In conclusion, smoking and alcohol consumption play similar pathogenetic roles in either subsite; partial laryngeal resection gave a higher rate of laryngeal preservation than did radiotherapy; and anatomic peculiarities of the subsites influence tumor behavior.

[Induction chemotherapy and larynx preservation: is such practice useful?]. / Chimiothérapie d'induction et préservation laryngée qu'en est-il en pratique?

BACKGROUND: Surgery followed by irradiation is considered to be the standard treatment but require frequently a total laryngectomy. Chemotherapy followed by irradiation is available in larynx and hypopharynx squamous cell carcinoma (SCC) treatment. Are results obtained in daily induction chemotherapy usefulness identical to results obtained in larynx preservation studies? PATIENTS AND METHOD: We conducted a retrospective study on patients treated at centre Oscar-Lambret, Lille, from 1986 to 1995, by chemotherapy followed by definitive radiotherapy or by surgery and radiotherapy for laryngeal or hypopharyngeal cancer treatment. All patients were naive of previous head and neck SCC and a surgical treatment, requiring total laryngectomy, should be proposed with curative intent. Induction chemotherapy associated cisplatin (100 mg/m2) on day 1 and 5-fluorouracil (5FU)(1,000 mg/m2) on days 1-4 or 1-5. Irradiation was performed for responders (complete or partial > 50%). If case of non-responder, patients underwent surgical treatment followed by irradiation. We compared results obtained with patients enrolled in clinical trial and with patients whom benefited from this protocol out of trial. RESULTS: Hundred-eight patients were evaluable for purposes of this study. Fifty-two patients were included in clinical trial (group 1) while 56 patients (group 2) were not. There was no statistical difference as regard neither to sex nor to node (palpable or not palpable) and metastasis status between the groups. We found a higher frequency of laryngeal tumour in group 2 (31 vs 17; p =.03). We observed more stage III and less stage IV in group 1. For chemotherapy-related toxic reactions, the exclusive statistical difference observed was haematological toxicity grade III and IV after the second cycle (0 pt in group 1 vs 8 pts in group 2; p =.02). After initial treatment, complete response was achieved without statistical difference between the groups (88.2% vs 78%; p =.27). A surgical procedure was performed in 46 cases without difference according to the reference group and functional larynx preservation was 55.8% (29/52) in group 1 and 53.6% (30/56) in group 2. Whatever the group, causes of death were similarly distributed. Cancer was the first cause of death in both groups. The overall survival of the population (108 patients) was 81.5% at one year, 49.6% at 3 years and 35.3% at 5 years with a median survival of 3 years. There was no statistical difference between both groups. Some parameters influenced the overall survival like T (p =.04), response to chemotherapy (p=.006), extra capsular spread (p = 0.03) and response after completion treatment. CONCLUSION: Induction chemotherapy is available for larynx preservation but cannot be considered as a standard treatment. Nevertheless, results should be reproduced in daily practice with experimented teams as found with non included patient's results. The long-term side effects of such protocols should be evaluated. Recent publication, on increase postoperative infection after chemotherapy, should be evaluated in clinical trial. If confirmed, cost effectiveness of such complication must be integrated in larynx preservation protocols. Larynx preservation remains an interesting point of view for patients but stay an optional procedure and not a reference.
