The aim of this study was to detect lower lip squamous cell carcinomas (SCC) that had metastasized to the lymph nodes and to evaluate if neck dissection was necessary for patients with T1 or T2-stage lip cancer after a sentinel lymph node biopsy (SLNB). The study was conducted as a prospective clinical study to detect occult neck metastases in patients with T1 or T2 stage SCC of the lower lip. Thirty-one patients were eligible and underwent echo-ultrasound, computer tomography, magnetic resonance and lymphoscintigraphy (LSG) as diagnostic procedures. LSG was performed on the same day as the surgical procedure, after intradermal injection of 37 Mbq Tc99m-Sn-colloid/mL at four peritumoral sites. In patients with positive LSG results, the sentinel lymph nodes were extracted surgically. The risk factors for cancer development were sun exposure and smoking. The highest accuracy for detecting lymph node enlargements was achieved with magnetic resonance imaging (MRI; 80.7%). LSG showed excellent sensitivity (100%) and negative predictive value (NPV; 100%). Overall, occult metastases were diagnosed with an SLNB in eight (25.8%) patients. According to the results, with great caution, we suggest that an SLNB is reasonable to initiate only for patients with positive sentinel nodes by positive LSG, to be used as a lower morbidity approach for selected patients with T1 and T2 stage cancers.

Treatment of squamous cell carcinoma of the lip is primarily surgical. Unlike other oral lesions, lower lip cancers do not metastasize to lower cervical lymph nodes without invading submental and submandibular lymph nodes. This study presents 30 patients with NO lower lip carcinoma who were treated by en bloc resection of the tumor with suprahyoid neck dissection. Occult metastasis was found in 4 patients (13%). Four patients, 3 of whom had no occult metastases, died of local or regional uncontrollable disease. Suprahyoid or modified radical neck dissection appears to be beneficial, even in small tumors of the lower lip, in detecting occult metastases.

Abstract In a study on cytological specimens from 30 cats with histologically confi rmed cutaneous squamous cell carcinoma, the morphometric variables mean nuclear area (MNA, μm2), mean nuclear perimeter (MNP, μm), mean nuclear diameter (D mean, μm), minimum nuclear diameter (D min, μm) and maximum nuclear diameter (D max, μm) were studied and compared to metastases in regional lymph nodes. The mean values of these parameters were signifi cantly greater in cats with lymph node metastases compared to parameters of tumour cells from cats which were lymph node-negative. A signifi cant positive correlation was observed between all studied morphometric parameters and metastases in the regional lymph nodes. In conclusion, computer -assisted nuclear morphometry could be used as a prognostic method in the diagnosis of spontaneous feline cutaneous squamous cell carcinomas.

A cross sectional study of 29 cases of oral squamous cell carcinoma with or without  cervical lymph node metastasis was done among Bangladeshi patients from January 2006 to December 2007. Majority of the study subjects (34.5%) belonged to the age group of 40-49 years. 58.6% of the study subjects were male, while remaining 41.4% of them were female. 51.7% of the lesions were located in the alveolar ridge where the other common sites were buccal mucosa (27.6%) and retro molar area (13.8%). Half of the study subjects (51.7%) were habituated to betel quid chewing followed by 37.9% and 10.3% were habituated to smoking and betel quid-smoking respectively. Grade I lesions was most prevalent (75.9%) in the study subjects.  Majority of cases presented with Stage IV lesions (55.2%). The sensitivity, specificity, positive predictive value, negative predictive value & accuracy of clinical palpation method for determining metastatic cervical lymph nodes were 93.33%, 64.29%, 73.68%, 90% and 79.3% respectively. Careful and repeated clinical palpation plays important role in evaluation of cervical lymph nodes though several modern techniques may help additionally in the management of oral cancer.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13978 Update Dent.

The analysis of the diagnostic informativeness of modern radiodiagnosticis methods in determining metastatic lymph node of pelvic cancer gynecological organs according to domestic and foreign publications. At the present stage methods of obtaining visual images pelvic lymph nodes are radiodiagnostics technologies (radiological, ultrasound, magnetic resonance tomography, scintigraphic). The analysis has shown that the researches devoted to diagnostic informational content of modern methods of radiodiagnosis in a differentiation of nature of damage of pelvic lymph nodes aren't enough. According to the literature, the most rational and perspective method for radiodiagnosis metastatics lymph node is a magnetic resonance imaging due to the high information content and thus specificity. At the same time, the continued relevance of further study of methods of radiodiagnostics in order to find the optimal one for the assessment of pelvic lymph nodes.
