    Tumor thickness as a predictive factor of lymph node metastasis and disease recurrence in T1N0 and T2N0 squamous cell carcinoma of the oral tongue
    (2014) MATOS, Leandro Luongo de; MANFRO, Gabriel; SANTOS, Ricardo Vieira dos; STABENOW, Elaine; MELLO, Evandro Sobroza de; ALVES, Venancio Avancini F.; PINTO, Fabio Roberto; KULCSAR, Marco Aurelio Vamondes; BRANDAO, Lenine Garcia; CERNEA, Claudio Roberto
    Objective. The aim of the study was to compare the thickness of primary tumors with the frequency of nodal metastases and survival in patients surgically treated for T1/T2N0 oral tongue squamous cell carcinoma. Study Design. This is a retrospective longitudinal study with 74 patients. Results. None of the patients with a tumor thickness (TT) <= 7 mm presented with nodal metastasis, whereas 25 of the patients with a TT > 7 mm (51.0%) developed metastases (P < .0001). Multivariate analysis showed that TT > 7 mm was a risk factor for occult nodal metastasis (odds ratio = 8.7; P = .002) with 81.9% accuracy. TT > 10 mm was also a predictive factor of worse disease-free survival in these patients (hazard ratio = 12.2; P = .003). Conclusions. Tumor thickness of greater than 7 mm is predictive of a higher incidence of lymph node metastasis, and a TT > 10 mm is predictive of worse disease-free survival in squamous cell carcinoma of the oral tongue.

    Delayed postoperative radiation therapy in local control of squamous cell carcinoma of the tongue and floor of the mouth
    (2014) AMAR, Ali; CHEDID, Helma Maria; CURIONI, Otávio Alberto; DEDIVITIS, Rogério Aparecido; RAPOPORT, Abrão; CERNEA, Claudio Roberto; BRANDÃO, Lenine Garcia
    Objective To evaluate the effect of time between surgery and postoperative radiation therapy on local recurrence of squamous cell carcinoma of the tongue and floor of the mouth. Methods A total of 154 patients treated between 1996 and 2007 were selected considering local recurrence rate and time of the adjuvant radiotherapy. Results Local recurrence was diagnosed in 54 (35%) patients. Radiation therapy reduced the rate of local recurrences, although with no statistical significance. The time between surgery and initiation of postoperative radiotherapy did not significantly influence the risk of local recurrence in patients referred to adjuvant treatment (p=0.49). Conclusion In the presence of risk factors for local recurrence, a short delay in starting the adjuvant radiation therapy does not contraindicate its performance.

    (2013) AMAR, Ali; RAPOPORT, Abrao; CURIONI, Otavio Alberto; DEDIVITIS, Rogerio Aparecido; CERNEA, Claudio Roberto; BRANDAO, Lenine Garcia
    The presence of metastatic nodes is a survival-limiting factor for patients with mouth tumors. Objective: To evaluate the causes of treatment failure in carcinomas of the tongue and floor of the mouth due to staging. Method: This study included 365 patients with squamous cell carcinoma of the mouth treated from 1978 to 2007; 48 were staged as T1, 156 as T2, 98 as T3, and 63 as T4, of which 193 were pNo and 172 pN+. Results: Among the pN+ cases, 17/46 (36.9%) of the patients not treated with radiation therapy had relapsing tumors, against 46/126 (36.5 %) of the patients who underwent radiation therapy. Success rates in the group of subjects submitted to salvage procedures were 16/51 (31.3%) for pN0 patients and 3/77 (3.9%) for pN+ patients. Conclusion: Salvage procedure success and survival rates are lower for pN+ patients; pN+ individuals also have more relapsing local disease.

    Negative and positive predictive values of nerve monitoring in thyroidectomy
    (2012) CERNEA, Claudio R.; BRANDAO, Lenine G.; HOJAIJ, Flavio C.; CARLUCCI JR., Dorival De; BRANDAO, Jose; CAVALHEIRO, Beatriz; SONDERMANN, Adriana
    Background Recurrent nerve injury is 1 of the most important complications of thyroidectomy. During the last decade, nerve monitoring has gained increasing acceptance in several centers as a method to predict and to document nerve function at the end of the operation. We evaluated the efficacy of a nerve monitoring system in a series of patients who underwent thyroidectomy and critically analyzed the negative predictive value (NPV) and positive predictive value (PPV) of the method. Methods. NIM System efficacy was prospectively analyzed in 447 patients who underwent thyroidectomy between 2001 and 2008 (366 female/81 male; 420 white/47 nonwhite; 11 to 82 years of age; median, 43 years old). There were 421 total thyroidectomies and 26 partial thyroidectomies, leading to 868 nerves at risk. The gold standard to evaluate inferior laryngeal nerve function was early postoperative videolaryngoscopy, which was repeated after 4 to 6 months in all patients with abnormal endoscopic findings. Results. At the early evaluation, 858 nerves (98.8%) presented normal videolaryngoscopic features after surgery. Ten paretic/paralyzed nerves (1.2%) were detected (2 unexpected unilateral paresis, 2 unexpected bilateral paresis, 1 unexpected unilateral paralysis, 1 unexpected bilateral paralyses, and 1 expected unilateral paralysis). At the late videolaryngoscopy, only 2 permanent nerve paralyses were noted (0.2%), with an ultimate result of 99.8% functioning nerves. Nerve monitoring showed absent or markedly reduced electrical activity at the end of the operations in 25/868 nerves (2.9%), including all 10 endoscopically compromised nerves, with 15 false-positive results. There were no false-negative results. Therefore, the PPV was 40.0%, and the NPV was 100%. Conclusions. In the present series, nerve monitoring had a very high PPV but a low NPV for the detection of recurrent nerve injury. (C) 2011 Wiley Periodicals, Inc. Head Neck 34: 175-179, 2012

    The surgical management of parotid gland tumours
    Background: The parotid tissue can give rise to a large variety of benign and malignant neoplasms. The objective of this study was to describe the management and outcome of parotid gland tumours over a 15-year period. Method: The records of consecutive patients treated by parotid gland excision from January 1995 to December 2008 were reviewed retrospectively. Data recorded were age, gender, history, physical findings, surgical procedure, fine-needle aspiration biopsy (FNAB), final pathological diagnosis and complications. Results: The vast majority of patients (306) had benign neoplasms, and 14 patients had malignant neoplasms. Overall, pleomorphic adenoma contributed to 76% of the lesions, and Warthin's tumour to 17%. The sensitivity and specificity of FNAB was 79% and 100%, respectively. There were 15 cases of marginal mandibular transitory paresis and 12 cases of seroma. Marginal mandibular definitive paralysis was observed in three cases with malignant tumour. Conclusion: Standardised parotidectomy is a safe operation, with a low complication rate.

    Successful parathyroid tissue autograft after 3 years of cryopreservation: a case report
    (2014) LEITE, Ana K. N.; JUNIOR, Climerio P. do N.; ARAP, Sergio S.; MASSONI, Ledo; LOURENCO, Delmar M.; BRANDAO, Lenine Garcia; MONTENEGRO, Fabio L. de M.
    After a total parathyroidectomy, well-established protocols for the cryopreservation of parathyroid tissue and for the delayed autograft of this tissue exist, especially in cases of secondary hiperparathyroidism (HPT) or familial or sporadic parathyroid hyperplasia. Although delayed autografts are effective, the published success rates vary from 10% to 83%. There are numerous factors that influence the viability, and therefore the success, of an autograft, including cryopreservation time. Certain authors believe that the tissue is only viable for 24 months, but there is no consensus on how long the parathyroid tissue can be preserved. A 63-year-old male who was diagnosed with sporadic multiple endocrine neoplasia type 1 and primary hyperparathyroidism, and was submitted to a total parathyroidectomy and an autograft in the forearm. The implant failed, and the patient developed severe hypoparathyroidism in the months following the surgery. Thirty-six months after the total parathyroidectomy, the cryopreserved autograft was successfully transplanted, and hypoparathyroidism was reversed (most recent systemic parathyroid hormone, PTH, of 36 pg/mL, and total calcium of 9.1 mg/dL; no oral calcium supplementation). The case presented here indicates that cryopreserved parathyroid tissue may remain viable after 24 months in storage, and may retain the capacity to reverse permanent postsurgical hypoparathyroidism. These data provide reasonable evidence that the time limit for cryopreservation remains undetermined and that additional research would be valuable.

    Biometric measurements involving the terminal portion of the thoracic duct on left cervical level IV: an anatomic study
    (2016) LOUZADA, Andressa Cristina Sposato; LIM, Soo Jin; PALLAZZO, Jaqueline Fabiano; SILVA, Viviane Passarelli Ramin; OLIVEIRA, Ruan Vitor Silva de; YOSHIO, Alvaro Masahiro; ARAUJO-NETO, Vergilius Jose Furtado de; LEITE, Ana Kober Nogueira; SILVEIRA, Andre; SIMOES, Cesar; BRANDAO, Lenine Garcia; MATOS, Leandro Luongo de; CERNEA, Claudio Roberto
    To determine the point of entrance of the thoracic duct in the venous system, as well as to evaluate some biometric measurements concerning its terminal portion, we conducted an anatomic study on 25 non-preserved cadavers. The termination of the thoracic duct occurred on the confluence between the left internal jugular vein and the left subclavian vein in 60 % of the individuals. The average results for the biometric measurements were: distance between the end of left internal jugular vein and omohyoid muscle 31.2 +/- A 2.7 mm; distance between the end of thoracic duct and the left internal jugular vein 0.0 +/- A 0.0 mm; distance between the end of thoracic duct and the left subclavian vein 3.6 +/- A 1.0 mm; distance between the end of thoracic duct and the left brachiocephalic vein 10.7 +/- A 3.1 mm. Moreover, it was identified that the left internal jugular vein length in level IV, measured between its entrance in the left subclavian vein and the omohyoid muscle, was able to predict the termination of the thoracic duct on the junction between the left internal jugular vein and the left subclavian vein (OR = 2.99) with high accuracy (79.3 %). In addition, the left internal jugular vein length at level IV was able to predict the localization of thoracic duct termination. Thus, this finding has practical value in minimizing the risk for a potential chyle leak during or after a left-sided neck dissection.
