J Craniomaxillofac Surg 2018; 47:47-52. [PMID: 30528947 DOI: 10.1016/j.jcms.2018.09.036] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2018] [Revised: 08/20/2018] [Accepted: 09/10/2018] [Indexed: 01/10/2023] Open
Abstract
PURPOSE To evaluate whether elective neck dissection (END) was beneficial for cN0 patients with salivary gland carcinoma. MATERIALS AND METHODS The rates of regional failure-free survival and disease-free survival were calculated using Kaplan-Meier methods and Cox models. The risk factors for occult lymph node metastasis (OLNM) in cN0 patients undergoing END was analyzed using logistic regression. A nomogram was formulated to calculate the estimated probability of OLNM. RESULTS Neck dissection was performed in 84 patients (43.3%). OLNM was detected in eight of the patients who underwent END. During the follow-up period, regional recurrences involving cervical lymph nodes were found in 10 patients. Cox model analysis revealed that neck dissection was not related to regional failure-free survival and disease-free survival. Logistic regression analysis revealed that older age, neural symptoms, and positive adjacent lymph nodes were associated with OLNM. A nomogram comprising age, neural symptoms, and adjacent lymph nodes was developed to predict the risk of OLNM. CONCLUSION The incidence of OLNM was low in cN0 patients after detailed preoperative evaluations. There was no strong evidence supporting END as a conventional therapy in cN0 patients with salivary cancers. Our nomogram is a simple and practical instrument for strengthening the prediction of OLNM.

Abstract
Difficulty in precise decision making on necessity of surgery is a major problem when managing oral squamous cell carcinomas (OSCCs) with clinically negative neck. Therefore, use of clinical and histopathological parameters in combination would be important to improve patient management. The main objective is to develop a model that predicts the presence of nodal metastasis in patients with OSCC.623 patients faced neck dissections with buccal mucosal or tongue squamous cell carcinoma (SCC) were selected from patients’ records. Demographic data, clinical information, nodal status, Depth of invasion (DOI) and pattern of invasion (POI) were recorded. The parameters which showed a significant association with nodal metastasis were used to develop a multivariable predictive model (PM). Univariate logistic regression was used to estimate the strengths of those associations in terms of odds ratios (OR). This showed statistically significant associations between status of the nodal metastasis and each of the following 4 histopathological parameters individually: size of the tumour (T), site, POI, and DOI. Specifically, OR of nodal metastasis for tongue cancers relative to buccal mucosal cancers was 1.89, P-value < 0.001. Similarly, ORs for POI type 3 and 4 relative to type 2 were 1.99 and 5.83 respectively. A similar relationship was found with tumour size; ORs for T2, T3, and T4 compared to T1 were 2.79, 8.27 and 8.75 respectively. These four histopathological parameters were then used to develop a predictive model for nodal metastasis. This model showed that probability of nodal metastasis is higher among tongue cancers with increasing POI, with increasing T, and with larger depths while other characteristics remained unchanged. The proposed model provides a way of using combinations of histopathological parameters to identify patients with higher risks of nodal metastasis for surgical management.

Abstract
PURPOSE OF REVIEW As patients with HIV infection are living longer with their disease, we have seen the evolution of skin cancer in this population. Cancer registries have not documented the incidence and prevalence of these cancers but we do have relevant data from cohorts. This article attempts to bring to light the extent to which skin cancer is an issue in HIV disease both domestically and internationally. RECENT FINDINGS Squamous cell cancer is increasing in incidence in the United States and elsewhere. The anatomic locations of skin cancer vary according to demographics, host factors, and environment. In this review, squamous cell cancer will be contrasted to the other skin cancers namely, melanoma, and basal cell cancers. SUMMARY As our HIV population ages, clinicians should be informed as to the relevant risk factors for development of skin cancer. With the increasing incidence of these cancers in the modern era of HIV, clinicians and researchers will be informed with regard to prevention and treatment strategies.
