schwannomas are benign nerve sheath tumors that originate from any anatomical site. most of the schwannomas are found in the head, neck or limbs. schwannoma arising in a lymph node is extremely rare. we have found only four cases in the review of the literature. we experienced a case of intranodal schwannoma in a perigastric lymph node. a 72 year-old female underwent cholecystectomy due to clin...

BACKGROUND The current study was conducted to develop a multifactorial statistical model to predict the specific head and neck (H&N) tumor site origin in cases of squamous cell carcinoma confined to the cervical lymph nodes ("unknown primaries"). METHODS The Surveillance, Epidemiology, and End Results (SEER) database was analyzed for patients with an H&N tumor site who were diagnosed between ...

JNCI Vol. 100, Issue 10 | May 21, 2008 The presence of cervical lymph node metastasis is an important prognostic factor in patients with head and neck squamous cell carcinoma (HNSCC). However, the management of patients without neck metastases, as determined from physical examination (ie, clinically negative neck, cN0), remains controversial ( 1 , 2 ). These patients usually undergo elective ne...

BACKGROUND This study was aimed at investigating the role and molecular mechanism of Sam68 in cervical cancer lymph node metastasis. MATERIALS AND METHODS Sam68 expression profile was detected by quantitative polymerase chain reaction, western blotting and immunohistochemical staining. Short hairpin RNA interfering approach was employed to suppress endogenous Sam68 expression in cervical canc...

OBJECTIVE By performing sentinel lymph node (SLN) biopsy, its detecting and predictive value to the cervical metastasis in the head and neck cancer patients was studied. METHODS Intraoperative SLN biopsy was done in 51 untreated head and neck cancer patients who all had no metastasis before operation. The lesions were: laryngeal cancer 23, pharyngeal cancer 6, thyroid cancer 20 and cancer of ...

PURPOSE We performed this network meta-analysis to compare the diagnostic value of 4 imaging methods (magnetic resonance imaging, positron emission tomography, computed tomography, and diffusion-weighted imaging) for diagnosing lymph node metastases in cervical cancer. METHOD Diagnostic tests regarding different imaging methods to diagnose lymph node metastases in cervical cancer were retriev...

BACKGROUND The initial draining lymph node for a primary tumor is referred to as the "sentinel" node. Firstly adopted in the management of patients with cutaneous melanoma and breast cancer, it is now widely tested in cervical cancer. In patients with cervical cancer, lymph node status is the most important prognostic factor for survival. In patients with cervical cancer FIGO stage I and II pel...

Cervical lymph node metastases are very common in patients with papillary thyroid cancer (PTC). Despite that PTC has an excellent prognosis, lymphatic spread is associated with increased risk of loco-regional recurrence, which significantly impairs quality-of-life and can alter prognosis of the patient. Therefore, the identification of lymph node metastases preoperatively is very important for ...

In most cancers of epithelial origin, metastases to the lymph nodes constitute the most important prognostic factor and are predictive of the results of the surgical and adjuvant therapies. Data on the lymph node status allows to design an appropriate treatment plan. Despite advances in gynecologic oncology the importance of lymph node micrometastases in cervical cancer especially in nonsentine...

OBJECTIVE This study was to evaluate the treatment outcomes and prognostic factors of patients treated with salvage radiotherapy for the treatment of isolated lymph node recurrence of cervical cancer. METHODS Between 1990 and 2009, 22 cervical cancer patients with lymph node recurrence who had previously undergone radical hysterectomy and pelvic lymph node dissection were treated with salvage...
