Influence of bethanechol on salivary parameters in irradiated patients
2017
Background Some studies have shown evidence that the prophylactic use of bethanechol chloride (BC) may be useful in preventing the incidence and/or severity of xerostomia (XT). However, the indication of BC in irradiated patients with XT needs to be better characterized. The study aimed to evaluate the influence of BC on XT, salivary flow rate, and salivary composition in patients previously submitted to head and neck radiotherapy. Material and Methods Forty five irradiated patients complaining of XT used 50 mg/day of BC for 3 months, and the salivary parameters were evaluated in 4 Phases (Before BC therapy, after one month of BC, 2 months of BC, and 3 months of BC). Biochemical analysis in…
Effects of sex on naevus body distribution and melanoma risk in two melanoma case-control studies at different latitudes
2016
Naevus count is the most predictable phenotypic risk factor for melanoma and is mainly influenced by genetic factors1,2,3. Melanoma disparities according to gender have been reported in many studies in term of body distribution, survival and to a lesser extent incidence1,2. It is well established that women are more likely to get melanoma on the lower limbs, whilst men are more prone to melanoma on the trunk. In this study, we explore the effects of gender on the distribution of naevi on the body in melanoma cases and controls from different latitudes and whether the odds ratios for melanoma associated with naevi at different body sites are affected by gender. Two case control studies are c…
Lower lip squamous cell carcinoma in patients with photosensitive disorders : analysis of cases treated at the Brazilian National Cancer Institute (I…
2017
Background Lower lip squamous cell carcinoma (LLSCC) is a common malignancy of the head and neck, being mainly a consequence of a chronic exposure to ultraviolet (UV) light solar radiation. Here, we evaluated the clinicopathological profile of patients with photosensitive disorders (xeroderma pigmentosum, lupus erythematosus and albinism) that developed LLSCC. Material and Methods Data from patients who had a diagnosed LLSCC with a prior xeroderma pigmentosum, lupus erythematosus or albinism diagnosis that were treated at INCA from 1999 to 2012 were collected from patients’ medical records (n=16). The control group was composed of 68 patients with LLSCC without a medical history of photosen…
[Double second branchial cleft anomaly].
2009
Second branchial cleft anomalies are the most common of this type of neck masses. They can be classified in four types (Bailey/Proctor classification) according to their location. Type II is the most common, and related to vital neck structures such as the carotid artery and jugular vein. Cysts are the most frequent among them. Management consists of surgical excision of the cyst and tract by cervicotomy to avoid recurrence. We present an extremely rare case of a 32-year-old male who presented a sudden appearance of a right lateral neck mass that was identified by an image study as a double branchial cleft cyst. A review of simultaneous branchial cleft cyst in the literature is also made.
Treatment of recurrent and/or metastatic squamous cell head and neck carcinoma with a combination of vinorelbine, cisplatin, and 5-fluorouracil: a mu…
1995
Summary Purpose Vinorelbine has been demonstrated to be active against squamous cell carcinomas of the headneck (SCHNC) and lung. This multicenter phase II trial was carried out to evaluate the activity and tolerability of the combination of vinorelbine, cisplatin, and 5-fluorouracil given on an outpatient schedule in a series of 80 patients with recurrent SCHNC. Patients and methods Eighty patients with recurrent and/ or metastatic SCHNC were treated with a combination of CDDP 80 mg/m2 on day 1, 5-FU 600 mg/m2 as a 4-hour infusion on days 2-5, and vinorelbine 25 mg/m2 on days 2 + 8. This cycle was repeated every 28 days. Most patients had oral cavity, larynx, or oropharynx carcinoma (88%).…
Prophylaxis of radiogenic sialadenitis and mucositis by coumarin/troxerutine in patients with head and neck cancer--a prospective,randomized, placebo…
2001
To study the efficacy of coumarin/troxerutine for the protection of salivary glands and mucosa during irradiation. Design: Prospective, randomized, placebo-controlled, double-blind trial. Setting: University hospital, Germany. Patients: 48 patients who had radiotherapy to the head and neck. Main outcome measures: Salivary gland scintigraphy and acute side-effects of radiotherapy (Radiation Therapy Oncology Group (RTOG) score). Results: 23 patients (11 experimental, 12 placebo) completed the study. The global efficacy measure combining scintigraphy and RTOG score favoured the experimental arm (P= 0.07). The RTOG score showed significantly fewer acute side-effects of radiation in the experime…
Survival and prognostic factors in patients with oral squamous cell carcinoma
2020
Background This study aimed to evaluate sociodemographic and clinical factors influencing overall survival (OS) in patients with oral squamous cell carcinoma (OSCC). Material and Methods Medical charts of 547 patients with OSCC from a public hospital in northeastern Brazil seen between 1999 and 2013 were evaluated. Survival analysis was performed using the Kaplan-Meier method. The influence of age, sex, ethnicity, clinical stage, anatomical location, type of treatment, and comorbidities on the patients’ prognosis was evaluated. Cox proportional hazards regression model was used to identify independent prognostic factors. Results The 5-year OS was 39%. Multivariate analysis showed that age <…
Three-dimensional sonographic diagnosis of a large cystic neck lymphangioma.
2004
Lymphangiomas are fairly well-circumscribed benign masses of lymphatic vessels or channels that vary in size, are usually greatly dilated, and are lined with normal endothelial cells. They may be classified into 3 groups: lymphangioma simplex, consisting of capillary-sized channels; cavernous lymphangiomas, consisting of dilated channels with a fibrous adventitial covering; and cystic lymphangiomas, or hygromas, composed of multiple cysts of varying sizes that are lined with endothelial cells. Mixed types may coexist within a given lesion. Although lymphangiomas can occur in any part of the body where lymphatic ducts are located, 95% of them are found in the neck, the head, or the axilla. 1…
Head and neck squamous cell carcinoma in young patients : a 26-year clinicopathologic retrospective study in a Brazilian specialized center
2020
Made available in DSpace on 2020-12-10T20:02:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-05-01 Background: To describe the clinicopathologic profile of young patients with head and neck squamous cell carcinoma (HNSCC) and compare to middle-aged and elderly adults. Material and Methods: Patients' individual records were reviewed for clinicopathologic data. Eighty-nine patients with age 18-45 years old met the inclusion criteria of the study. Two additional groups of middle-aged (n=89) and old (n=89) adults were set to comparative analysis. Results: Young patients represented 11.9% of all patients diagnosed with HNSCC. Women were more affected by HNSCC in the young and elder gro…
The pesticides use and the risk for head and neck cancer: A review of case-control studies
2020
Background Tobacco, alcohol consumption, and HPV infection are the most common risk factors for head and neck cancer (HNC). Despite of this, recent evidences are growing on the association between long-term exposure to pesticides and the risk of chronic diseases, including different types of cancer. The present review evaluated in current literature evidence of an association between exposure to pesticides and the occurrence of HNCs. Material and Methods A literature search of the case-control studies was conducted in the PubMed, Web of science and Cochrane databases. Methodological quality of each study was rated with the Scottish Intercollegiate Guidelines Network (SIGN 50) checklist. Res…
