[Primary acinic cell carcinoma in mandible: a case report].

Acinic cell carcinoma is a relatively rare salivary gland tumor predominantly occurring in the major glands. Therefore, acinic cell carcinoma rarely occurs in the mandible. In this study, a case of primary acinic cell carcinoma of the mandible was reported, and relevant literature was reviewed.

Lymph node ratio is associated with adverse clinicopathological features and is a crucial nodal parameter for oral and oropharyngeal cancer.

The lymph node ratio(LNR) has been described as a novel predictor of the survival of patients with oral and oropharyngeal squamous cell carcinoma(O/OPSCC). The purpose of this study was to evaluate whether LNR is better at predicting survival and the need for adjuvant treatment than traditional tumour-nodal-metastasis(TNM) staging. Eight hundred nine patients with O/OPSCC and positive lymph node disease were retrospectively enrolled in this study.

Clinicopathological features, management and outcome of patients with poorly-differentiated oral and oropharyngeal squamous cell carcinoma.

Background: The purpose of this study was to explore the clinicopathological features, risk factors, and management of poorly differentiated oral and oropharyngeal squamous cell carcinoma (OOSCC) patients in the northern Chinese population.

Method: A total of 118 poorly differentiated OOSCC patients from 2236 consecutive cases were retrospectively enrolled in this study.

Results: Cox regression analysis showed that site (hazard ratio (HR): 2.

Predicting Radiotherapy Necessity in Tongue Cancer Using Lymph Node Yield.

Purpose: In patients with head and neck cancer and a single metastatic lymph node (pN1), the value of lymph node yield (LNY) remains controversial in determining the prognosis and identifying patients who require radiotherapy. This study evaluated the role of LNY in predicting the adequacy of neck dissection, need for adjuvant radiotherapy, and survival in patients with pN1 oral tongue squamous cell carcinoma.

Materials And Methods: The authors implemented a retrospective cohort study.

Second primary cancer after index head and neck squamous cell carcinoma in Northern China.

Objective: To evaluate the clinicopathologic features, prognostic factors, and management of patients in the North Chinese population with head and neck squamous cell carcinoma (HNSCC) who developed a second primary malignancy (SPM).

Methods: This was a retrospective study including 1818 eligible patients between June 1999 and April 2011.

Results: A total of 188 HNSCC patients developed SPM.

Risk factors for patients with multiple synchronous primary cancers involving oral and oropharyngeal subsites.

Objective: To evaluate risk factors and prognosis for multiple synchronous primary cancers (MSPCs) associated with head and neck squamous cell carcinoma.

Study Design: The retrospective study included 1623 patients.

Results: The most common MSPC site involved was the head and neck region.

Risk factors for relapse of middle-stage squamous cell carcinoma of the submandibular region and floor of mouth: the importance of en bloc resection.

Our aim was to investigate retrospectively the rate of recurrence in the intervening region for middle-stage squamous cell carcinoma (SCC) of the tongue and identify the factors that predict relapse and prognosis. A total of 204 patients were included, 96 in the en bloc group and 108 in the control group. The groups were comparable.
