Currently, allergic rhinitis (AR) is the most common allergic disease worldwide. AR is defined as immunoglobulin E (IgE)-mediated chronic inflammatory disease of the upper airways. It characterizes by symptoms like nasal obstruction, rhinorrhea, nasal itching, and sneezing. The immune system and genetic susceptibility in the interaction with the environment lead to the development of AR. Many cytokines, chemokines and cells maintain allergic inflammation. Studies show that 10% to 30% of the adult population are affected, and that prevalence rates are increasing world widely. AR, nasal polyps (NP), as well as chronic rhinosinusitis (CRS) are all associated with eosinophilic infiltration and large quantities of mast cells (MCs) within the mucosa. The diagnosis and management of chronic sinonasal diseases involves the analysis of eosinophilic infiltration, MCs, and their markers eosinophilic cationic protein (ECP) and tryptase. Regarding nasal cancer, nasal allergies were found to exhibit a dual function: immune surveillance may help in the defense against malignant cells, but an opposite effect is observed in tissues with chronic stimulation and inflammation. In the present paper, we studied a group of 70 patients diagnosed with AR and NP, rhinosinusitis or nasal cancer, admitted to the Ear, NoseThroat (ENT) Clinic of the Emergency City Hospital, Timişoara, Romania, between January 2016 and December 2020, and we identified 37 (53%) patients diagnosed with AR and NP, 25 (36%) patients diagnosed with AR and rhinosinusitis, and eight (11%) patients diagnosed with AR and nasal cancer. The average age of the patients was 53 years old. Every patient included in the study was histopathologically and immunohistochemically diagnosed.

The melanoma, having its origin in the melanocyte cells, is one of the most aggressive forms of skin cancer in the world with one of the highest rates of brain metastasis. The incidence of cutaneous melanoma in the Mediterranean countries varies from three to five cases∕100 000 people∕year. Its prognosis is based on an early diagnosis. Sinonasal mucosal melanoma (SNMM) is an extremely rare tumor, accounting for 0.3-2% of all melanomas. The non-specific symptomatology is often delaying the presentation of the patient at the hospital and therefore the diagnosis. The SNMM is a highly aggressive tumor, and the presence of metastasis at the diagnosis usually implies a poor prognosis. The management of the melanomas requires a precise pre-therapeutic assessment and a multidisciplinary approach for the diagnosis, with surgical treatment or radiotherapy required in order to ensure a better a quality of life. In this paper, we retrospectively analyzed two cases of mucosal melanoma and one case of cutaneous melanoma of the nose.

In the last decade, the incidence and mortality associated with laryngeal malignancies has experienced an unfavorable evolution in Romania, in terms of this pathology the country that has become the leader, among the European Union (EU)-27 countries. The aim of the present retrospective study was to analyze the epidemiological data regarding laryngeal cancer and histopathological (HP) particularities in patients diagnosed in Western Romania. Within three years and 10 months (during October 2016-July 2020) in Ear, Nose and Throat (ENT) Clinic of Timişoara Municipal Emergency Clinical Hospital, 194 patients with laryngeal neoplasms (LN) were diagnosed. Most of the patients were male (93.8%), from Timiş County, mainly and the neighboring Counties of Caraş-Severin, Hunedoara, Mehedinţi and Arad. Patient's average age (both sexes) was 62.6 years, with a range from 38 to 84 years and the highest percentages in the 60+ age group (48%). Regarding smoker status, the main cause of the development of the LN, 93.9% of patients were active ones. Regarding localization [International Classification of Diseases 11th Revision (ICD-11)], about 69% were malignant neoplasm of glottis (C32.0), followed by supraglottis (C32.1), larynx-unspecified (C32.9), and subglottis (C32.2). From the HP point of view, several types of tumors were identified, most of which were non-keratinized and keratinized squamous cell carcinomas (about 90%). In addition, there were identified types of verrucous carcinoma, acantholytic carcinoma, squamous papilloma, a possible pleomorphic sarcoma, and pyogenic granuloma. The data presented in this study highlight the growing incidence of LN, which mainly affect men, at an increasingly young age. It is imperative to involve specialists from nutrition, general medicine, ENT, dentistry to start awareness programs and to develop prevention protocols.

This retrospective study aimed to evaluate the outcomes of bilateral cochlear implantation in patients with severe-to-profound sensorineural hearing loss at the Timisoara Municipal Emergency Clinical Hospital ENT Clinic. The study involved 77 participants, divided into four groups based on their hearing loss characteristics and implantation history. Assessments were conducted pre- and post-implantation, focusing on speech perception, speech production, and reading achievement. Standard surgical procedures were performed, and participants were provided with a comprehensive rehabilitation program involving auditory training and communication therapy. The variables considered for analysis included demographic factors, implantation period, and quality of life assessment, with no statistically significant differences pre-implantation between the four study groups. Results revealed significant improvements in speech perception, speech production, and reading achievement after cochlear implantation. In adult patients, speech perception scores increased from 21.3% to 73.4% for WIPI and from 22.7% to 68.4% for HINT after 12 months of rehabilitation. Speech production scores improved from 33.5% to 76.8% and reading achievement scores increased from 76.2 to 106.3. Moreover, there was a significant improvement in patients’ quality of life following cochlear implantation, with mean scores increasing from 2.0 to 4.2. Although it is known that bilateral cochlear implantation significantly improves speech perception, speech production, reading achievement, and quality of life in patients with severe-to-profound sensorineural hearing loss, this is the first study of its kind from Romania. Further research is warranted to optimize patient selection and rehabilitation strategies to maximize outcomes and determine better policies towards funding and access of cochlear implants for a wider range of patients in need.

Chondrosarcoma (CHS) is a malignant tumor of soft tissue with cartilaginous differentiation that represent one tenth of all malignant proliferations developed from bone tissues. Even if CHS represents the third malignancy with bone localization, after myeloma and osteosarcoma, it is far less diagnosed in the head and neck region. The current paper presented two cases of conventional CHSs, which were diagnosed in Department of Thoracic Surgery and Department of Otorhinolaryngology of Emergency City Hospital, Timişoara, Romania, between February and June 2021. The malignant cases were of peripheral CHSs, one of scapula, and the other one had an extremely rare tracheal location with microscopic features of conventional low-grade tumors (grade 1). In all cases, conservative surgical curative treatment was performed, with a favorable postoperative evolution.

Due to their anti-inflammatory, antiangiogenic and antiedematous properties, corticosteroids have been commonly used in the treatment of retinal diseases. Intravitreal administration of steroids offers the maximal drug efficacy and the lowest risk of systemic side effects. The authors report three cases of presumed sterile endophthalmitis induced by triamcinolone acetonide (TA) in three eyes with intermediate non-infectious uveitis. Each patient received a single intravitreal injection of TA of 4 mg. Because of the intense vitreous inflammatory reaction, retina examination and the optical coherence tomography could not be performed, although vitreous opacities were observed on the ocular ultrasound. The dense vitreous opacity is a defining factor, the anterior segment inflammation is mild to moderate and a hypopyon is present, which may be a sterile inflammatory reaction or the triamcinolone material itself. In cases of sterile endophthalmitis, the visual acuity increases progressively as the intraocular inflammation diminishes. Local treatment with topical antibiotics, prednisolone acetate and cycloplegic eyedrops is recommended to control the inflammatory reaction.

Multiple primary tumors (MPT) represent an important factor affecting the survival of some patients. They present an incidence of about 0.7-11% of all carcinomas developing in any region of the human body, being either synchronous or metachronous. These tumors raise problems of differential diagnosis, with tumoral relapses and distance metastases; also, they involve problems related to chemotherapy, radiotherapy and surgical treatment. In the present paper, we studied a group of 902 patients diagnosed with head and neck tumors admitted to the Ear, NoseThroat (ENT) Clinic of the Emergency County Hospital of Timişoara, Romania, and we identified 12 patients with metachronous tumors, representing 1.33% of the hospitalized cases. Of the 12 patients with metachronous tumors, a single case was a woman, the other 11 cases being diagnosed in men. Regarding the age of the patients with metachronous tumors, only a single patient was aged less than 60 years old; most of them (nine patients) were aged between 60 and 69 years old, while two patients were aged over 70 years old. Nine patients were alcohol consumers, while 10 (83.33%) patients were smokers of about 20 cigarettes∕day. All the metachronous tumors localized in the head and neck were squamous cell carcinomas. The second primary tumor was identified in the prostate, kidneys, ureter, lungs, salivary gland, thyroid gland, meninges, colon, rectum or skin.

The aim of this study was to reveal the important role of CEUS in identifying correctly benign hepatic lesion vs a malignant one. We report a case of a diffuse hepatic steatosis particular sonographic aspect in a middle aged male presenting with general malaise. History revealed cardiac pathology, diabetes mellitus type 2 and chemotreated prostate neoplasia. The abdominal ultrasound (US) presented numerous hyperechoic lesions disseminated in the whole parenchyma. A contrast enhanced ultrasound (CEUS) of the lesions described an isoenhancement pattern of the lesions in the arterial phase, followed by the same aspect in the venous phase, with a high uptake pattern in the late phase. The CT and MRI also confirmed a diagnosis of a benign pathology. Hepatic steatosis may occur in chemotreated cancer patients, raising a suspicion of hepatic metastasis, but also due to the amount of lipid deposit distribution in the liver. Thus, CEUS was able to establish a correct diagnosis in a fast and reliable way.

A number of studies highlight the harmful effects of smoking and the extremely serious consequences of the majority of compounds found in cigarettes and cigarette smoke. Of these, nicotine has attracted attention due to the suspicion of a carcinogen compound. The present study investigated the effect of nicotine on primary gingival keratinocytes but also on pharyngeal tumor cells, by evaluating viability and apoptotic processes.

The study present a case of splenic lymphoma in a middle-aged male, showing up with abdominal pain, weight loss and recurrent oral candidosis. Blood test revealed remarkable leukocytosis, anemia and thrombocytopenia. Abdominal ultrasound showed marked splenomegaly with multiple hyperechogenic lesions. Contrast enhanced ultrasound (CEUS), performed on the lower pole of the spleen, showed a lesion lightly hypoenhanced in the arterial time, with progressive washout and marked hypoenhancement in the late phase, raising the suspicion of a malignant pathology. MRI results were consistent with a high suspicion of splenic malignancy, a possible lymphoid infiltration. The peripheral blood smear revealed lymphocytosis with villous lymphocytes, a variant form of hairy cell leukaemia. Iliac crest bone marrow biopsy confirmed the diagnosis. Our aim behind highlighting the topic is to underline the role of CEUS in identifying a malignant lesion, promptly leading us to further hematological investigation.

Our study aimed to determine pain levels and the state of welfare connected to laser-based procedures in the treatment of patients diagnosed with uncontrolled glaucoma. The study group included 100 eyes of 100 patients diagnosed with glucoma, 50 of them being treated with micropulse transscleral laser cyclophotocoagulation, and the other 50 eyes being treated with continuous transscleral laser cyclophotocoagulation. We used visual analog scale to gather information from each patient. After analysing the individual information the following results were obtained: the pain level for the micropulse transscleral laser cyclophotocoagulation was 60.23 mm, signifying moderate pain; and the pain score for the continuous transscleral laser cyclophotocoagulation was 76.34 mm, corresponding to moderate-intense pain. Pain level generated by minimally invasive laser procedures is discussed.

Human papilloma virus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) has been recognized as a distinct disease entity associated with oral HPV infection with high-risk serotypes, mainly among white man at younger age. Lifetime number of oral sex partners of HPV-positive OPSCC patients is the strongest risk factor associated. HPV type 16 is now established as oncogenic and it is the main cause (over the 80%) of this type of OPSCC, followed by HPV 18 (3%). Nowadays, it is reported a dramatic rising of HPV-positive OPSCC, mainly in developed countries, including Australia, Canada, Denmark, Netherlands, Norway, Sweden, Poland, Slovakia, Switzerland, Estonia, France, Japan, United States (US) and United Kingdom. At present, the yearly number of new incidence OPSCC cases given to HPV worldwide has been estimated of 29 000 by the International Agency for Research on Cancer (IARC). If incidence trends continue, the annual number of HPV-positive oropharyngeal cancers is expected to overcome the annual number of cervical cancers by the year 2020, in the US.The aim of this paper is to review the recent data about several topics including risk factors of HPV-positive OPSCCs, guidelines in diagnostic evaluation, treatment, prognosis and prevention strategies, through prophylactic HPV vaccine on both sexes. Nowadays, HPV detection is a clinical standard of care for oropharyngeal malignancy by reporting tumors as HPV positive or p16 positive.

We report a case of rare benign tumor of the larynx - amyloidosis of larynx - in a 52-year-old female who presented to the Department of Ear, Nose and Throat (ENT), Timişoara Municipal Hospital, Romania, with dysphonia. The patient's first presentation was in June 2012, with a polypoid formation localized on left vocal cord. The patient underwent a suspended microlaryngoscopy (SM) with tumor removal followed by histopathological examination, which revealed a laryngeal amyloidosis. The tumor recurred in 2013, 2014, 2016, 2017 and 2018. The patient underwent tracheotomy, followed by SM with endoscopic CO2 laser procedures, in order to remove the tumor and to ensure the airway. The follow-up was for six years. In May 2018, amyloid was located in subglottis, glottis and left false vocal fold. The patient needed five revision surgical procedures. The patient did not developed systemic amyloidosis during the follow-up period.

Osteonecrosis of the jaw (ONJ) is a multifactorial condition associated with bisphosphonates (BPs) treatment, head and neck irradiation, malignancy, chemotherapy, periodontal disease or trauma. The first cases of BPs-related ONJ (BRONJ) were reported over a decade ago.The study was retrospective and analyzed archived material. The study included 38 patients diagnosed and treated in the Clinic of Oral and Maxillofacial Surgery, Emergency City Hospital, Timişoara, Romania, for BRONJ, between 2013 and 2016. For all the cases were noted gender, age, localization of osteonecrosis, therapeutic indications for BPs (osteoporosis or malignancy), history of radiotherapy or chemotherapy, presence of bone metastases. If the treatment consisted in surgical removal of necrotic bone, the surgically removed specimens were sent to Service of Pathology of the same Hospital. The excised specimens were prepared with routine histological technique.All the patients included in the current study were diagnosed with BRONJ. The patient history and clinical characteristics were the most useful diagnostic methods. Radiographic changes are not significant in early stages of osteonecrosis. The prevalence of BPs-associated ONJ is higher between 55-74 years old.ONJ is an important complication of BPs medication. The majority of affected patients develop this complication after dentoalveorar surgery, especially after dental extraction. Therefore, a good state of dental health is one of the most important directives when dealing with potential candidates for BPs therapy.

Basal cell carcinoma (BCC) is the most common locally invasive malignant epidermal neoplasm. It is generally a tumor that runs a slow progressive course and can usually be cured by surgery. Basosquamous carcinoma is considered by some authors a rare subtype of BCC, while others describe it as independent tumor with different evolution from BCC. The aim of the study was to present a very interesting case of initially otherwise ordinary BCC that during its repeated and extensive relapses changed its histopathology in a basosquamous carcinoma, despite the free surgical margins and leading to major surgeries with loss of right eye. We present a case of 75-year-old male diagnosed in 2008 with a tumor located in the right naso-orbital region. The patient underwent surgical treatment, the histopathology being consistent with BCC. He presented recurrences of the tumor in 2009 and 2010 that were excised at approximately 9 and 16 months, respectively, from the first intervention. In 2010, the surgical procedure was radical, with removal of the tumor and the entire right superior eyelid. This approach proved to have negative side effects over the right eye in time. Therefore, after two months, a complete exenteration of the right orbit was necessary. The tumor recurred again for three times, after 20, 30 and 42 months from the first intervention and every time surgical treatment was applied. The microscopic inspection of the biopsies showed similarities between recurrences and initial tumor. In 2013, after 57 months from the first intervention, the patient was readmitted with a lesion in the same region that was excised but that time the histopathology differed from the previous, the tumor being composed of sheets of achromic epithelioid cells, with vesicular nuclei and prominent, eosinophilic nucleoli. The tumor cells were positive for pan-cytokeratin AE1∕AE3 and negative for S100 protein, human melanoma black 45 (HMB45) and vimentin that sustained the diagnosis of basosquamous carcinoma. The paper presented an interesting case with different histopathological features from a recurrence to other, with important implication in diagnosis and prognosis. The transformation of BCC into basosquamous carcinoma sustain that the basosquamous carcinoma is better a rare, aggressive variant of BCC, than an individual lesion.

Cervical lipomas are tumors that may present as painless masses with slow growth. This type of tumors is usually asymptomatic until they reach a large size. They can be solitary or multiple. When multiple and symmetrical distributed around neck area, the lesions can be classified as Madelung's disease, a rare condition that affects mostly Mediterranean men. Our objective was to describe the symptoms, cytological and histological aspects, diagnostic problems and treatment strategies of the large size lipomas and to highlights that the differential diagnosis between common lipoma of cervical area and Madelung's disease can be established only on clinical grounds, with major implications in the treatment options.The study was retrospective and analyzed archived material. We selected four cases of cervical lipomas, each with its particularities, treated in the Clinic of Oral and Maxillofacial Surgery, Timişoara City Hospital, Romania. For all the cases, we performed a fine-needle aspiration with consequent cytological exam. The microscopic evaluation of Papanicolaou-stained slides established the diagnosis of lipomas. The surgically removed specimens were sent to the Department of Pathology. The excised specimens were prepared with routine histological technique.The cases presented one or more lateral cervical swelling of the neck, inserted among major vascular-nervous elements, becoming life-threatening conditions. All the cases studied had the same cytological and histopathological features consistent with lipoma, fibrolipoma or angiolipoma, but, instead of this, clinical aspects differed from case to case. On clinical grounds, two patients were considered as Madelung's diseases.Despite of the same histopathological aspects, lateral cervical lipomas can be classified in varies categories with different treatment strategies and prognostic factors. The correct diagnosis of Madelung's disease is important in order to add other treatment options to the surgery or liposuction as avoiding alcohol or medication for metabolic disorders.

Anterior wall of the oropharynx or the base of the tongue is the site of different types of cancers, most of them usually diagnosed in advanced stages. The most common histological type of cancer diagnosed in these patients is squamous cell carcinoma (SCC). The treatment methods are multiple, but the optimal therapeutic option with best results on outcome and on the patients' quality life has not been established. The objectives of our study were to evaluate the tongue base SCCs treated by transhyoid approach and the oncological outcomes of the surgery combined with radiotherapy.The retrospective study was performed over a period of 10 years (2001-2010) on 37 previously untreated patients. All the tumors were biopsied and after histopathological (HP) diagnosis, the tumors were excised. All the specimens were fixed in 4% (v/v) buffered formalin and sent for the HP evaluation.In the study were included only the patient diagnosed on biopsy with different types of SCC. The mean age was 61 years old, most of the patients (94.59%) being males. We performed a tongue base transhyoid tumor resection in 23 (62.17%) cases followed by epiglottectomy in five (13.51%) cases or horizontal supraglottic laryngectomy in nine (24.32%) cases, respectively. Bilateral neck dissections and postoperative radiotherapy were performed in all cases. The postoperative and post-therapeutic evolution was favorable at three years (81.1%) and five years (75.67%). There were no signs of local or regional recurrences. The tumor specific three-year and five-year survival rates were: pT2 100%, pT3 87.5%, pT4a 71.42% and 57.14%, and pT4b 50% and 25%, respectively. The stage specific three-year and five-year survival rates were: stage II 100%, stage III 85.71%, stage IVA 83.33% and 79.16%, and stage IVB 50% and 25%, respectively.The prognosis for the SCC of the tongue base is poor. Cancer resection by transhyoid approach is a feasible procedure, which permits a good tumor control with limited postoperative morbidity, with an important benefit on the life quality of the patients.

Rare naso-sinonasal lesions represent a diagnostic challenge for clinicians because of the paucity of the cases and similarities with other more frequently sinonasal pathologies. The aim of the study was to present five rare sinonasal lesions in order to emphasize their symptomatology, imaging aspects, histopathological features, algorithms of diagnosis, and strategies of treatment and importance of teamwork between clinicians, pathologists and radiologists for a correct and prompt diagnosis.The cases were represented by patients with nasal sarcoidosis, nasal primitive neuroectodermal tumors, sinonasal mucosal melanoma, sinonasal plasmacytomas and nasal-type extranodal natural killer (NK) T-cell lymphoma. All the patients were biopsied in the Department of ENT (Ear, Nose and Throat), "Victor Babes" University of Medicine and Pharmacy, Timisoara, Romania, and the diagnosis was made using routine and immunohistochemical (IHC) stainings. The patients with sinonasal melanoma and the patient with extranodal NK T-cell lymphoma died in few months after diagnosis, despite treatment. Rare sinonasal lesions share similar symptomatology and imaging aspects with other, more frequently diagnosed entities. The cases reported in this paper showed the same pattern as those presented in other studies; the symptomatology, diagnosis, treatment and prognosis were the same. Clinical examination, imaging studies and routine and IHC markers guides us to the right diagnosis that should be prompt because of the prognosis of some tumors. The treatment has a few characteristics: surgery excision within safe margins, working with other specialties (oncology, radiotherapy, hematology, nephrology, pneumology), follow-up and correctly informing the patient being mandatory.In this paper, there were presented five interesting cases of rare sinonasal lesions, in order to highlight the importance of teamwork for a quick and correct diagnosis.

Extranodal natural killer (NK)÷T-cell lymphomas, nasal type are rare and aggressive non-Hodgkin's lymphomas (NHLs), with unknown etiology, rapid evolution and poor prognosis, due to midline tissue destruction and rapid spreading of the tumor. These lymphomas occur commonly in the nasal cavity and upper aerodigestive tract, but can also present involvement of the skin, salivary gland, and testis. We describe a case of nasal type T-cell NHL involving the nasal cavity and determining right thigh cutaneous metastases in a 47-year-old female associated with liver comorbidities and occupational dust exposure. The patient was suffering from chronic type C hepatitis and cirrhosis and she has been occupationally exposed to metal dust for 10 years. Clinical and laboratory investigations were performed. Essential for diagnosis and treatment protocol was nasal endoscopy and biopsy of nasal and cutaneous lesions. The histopathological exam was consistent with NK÷T-cell lymphoma. Patient was diagnosed in Ann Arbor stage IVA. Chemotherapy was initiated with Bleomycin, Etoposide, Adriamycin (Doxorubicin), Cyclophosphamide, Oncovin (Vincristine), Procarbazine and Prednisone, but it was stopped after two cycles because of the liver condition. The treatment plan also included radiotherapy, but soon after initiation, the patient died because of a liver complication. We present a rare case of extranodal NK÷T-cell lymphoma, nasal type, with cutaneous involvement to which the treatment could not be properly applied because of the late diagnosis and liver comorbidities.

Femtosecond laser-assisted cataract surgery is a new technique that offers the possibility to have some steps of the surgery done by an extremely precise machine with very high accuracy. Despite the high influence on the surgery steps of a nonsubjective machine, there are still some possible potential errors especially during the learning curve of the surgeon who is still crucial in both, the management and also the proceeding of the cataract surgery. We are reporting the case of a 61-year-old man, which was referred to our retinal department because of luxation of multiple lens fragments following femtosecond laser cataract surgery in his right eye, performed 1 day before. The anterior segment examination revealed residual lens cortex in the anterior chamber, an eccentric and intact anterior capsulorhexis, and a large posterior capsule rupture. During removal of the lens fragments from the posterior segment, a giant retinal tear was discovered in the infero-temporal periphery of the right eye, approximately 130 ° in circumferential extension, associated with a large subretinal lens fragment. Removal of the dropped lens fragments from both the vitreous and the subretinal space, as well as the management of the giant retinal tear are described. This case describes a rare intraoperative complication of a femtosecond laser-assisted cataract surgery, and we are trying to discuss different scenarios, which could have caused the capsular break and the retinal tear, thus offering possible pathways to prevent this kind of situations.

Laryngeal neoplasm contributes to 30-40% of carcinomas of the head and neck. Mast cells are normal connective tissue residents, well represented in the respiratory tract. Experimental evidence suggests that the growth of a tumor beyond a certain size requires angiogenesis, which may also permit metastasis. The aim of this study was to evaluate the correlation between mast cell density, microvascular density, histopathological type and histological grade. Our study included 38 laryngeal carcinomas as follows: adenoid cystic carcinoma (2 cases), malignant papilloma (2 cases) and squamous cell carcinoma (34 cases). The combined technique of CD 34-alcian blue safranin (ABS) was used to identify microvessel and mast cell density, which was quantified by the hot spot method. A significant correlation was found between both mast cell and microvascular density, and G1/G2 histological grade (p=0.002 and p=0.004, respectively). Squamous cell carcinoma was significantly correlated with mast cell density (p=0.003), but not with microvascular density (p=0.454).

The CO2 laser surgery represents a treatment method of laryngeal bicordal and anterior commissure glottic cancer T1b, T2, N0. In Department of ENT, Timisoara, Romania, during 1.01.2001-31.12.2011 were analyzed 781 files from patients with laryngeal neoplasm. One hundred twenty-seven patients presented the tumor that involved both vocal cords and anterior commissure, stages T1b, T2 and T3. Therapeutic options included CO2 laser microsurgical excision for 55 (43.30%) patients, frontolateral hemilaryngectomy for 16 (12.59%) patients, total laryngectomy for 42 (33.07%) patients, radiotherapy for 10 (7.87%) patients, and four (3.14%) patients, initially, refused any treatment modality. Endoscopic laser CO2 microsurgery was the primary and solitary management for curative resection of the glottic cancer. All operations were performed under general anesthesia with orotracheal intubations. The mean follow-up was 58 months, with the range between 36 to 84 months. Suspended microlaryngoscopy with CO2 laser surgery has been performed in 43 (33.85%) patients staged T1bN0Mx and 12 (9.44%) patients staged T2N0Mx. In five (9.09%) patients, we encountered local recurrences. The endoscopic CO2 laser surgery is in our view the elective and preferable surgical method in laryngeal glottic cancer stage T1b and T2 for cure, with oncological and functional results superior to those of conventional surgical procedures.

Molecular classifications of several malignancies are already accepted and applied in clinical practice. For head and neck squamous cell carcinomas (HNSCCs) there exist few and controversial data regarding their stratification on distinct groups or sub-groups and thus, none of them are validated as useful tools for diagnosis and therapy. Starting from the highly expressed markers in HNSCC (epidermal growth factor receptor, keratin 5 and E cadherin) we proposed to identify distinct HNSCC sub-groups with a potential impact on prognosis and therapy. Complex analysis of immunohistochemical expression for six surrogate markers (EGFR, p53, Bcl2, CD117, keratin 5 and E-cadherin) defined three distinct sub-classes amongst EGFR-positive cases, based on the association and differential expression of p53 and Bcl2 (EGFR(+)/p53(-)/bcl2(-), EGFR(+)/p53(+)/bcl2(-) and EGFR(+)/p53(+)/bcl2(+)). Amongst them, only the EGFR(+)/p53+/bcl2(-) sub-class showed significant correlations with grade and TNM parameters. Keratin 5-positive cases were grouped in a special "basal like" group with a particular sub-class rich in CD117(+)/p63(+) cells also highly expressing EGFR. Presence of K5(+)/CD117(+)/p63(+) cells was correlated with all TNM staging parameters defining a particular sub-class with high aggressiveness and particular behavior. Our data sustain EGFR as the key player in the pathogenesis of HNSCCs, but its diagnostic value may be improved by association with other prognostic or therapeutic markers. We herein defined two distinct HNSCCs groups (EGFR(+) and K5(+)) with several sub-classes, identifiable by the additional assessment of p53, Bcl2 and CD117.
