BACKGROUND: Cell-free DNA (cfDNA) extracted from blood has become a clinically feasible biomarker in various types of cancer. However, the clinical significance of cfDNA in gastrointestinal (GI) tract cancer among Asian populations requires further investigation. RESULTS: The median cfDNA copy number was highest in esophageal cancer, followed by colorectal cancer and gastric cancer, which were all significantly higher than those of healthy individuals. The cfDNA levels were higher in GI tract cancer, followed by those in carcinoma in situ and then healthy individuals (P = 0...

BACKGROUND: The follicular variant of papillary thyroid cancer (FVPTC), especially the encapsulated non-invasive subtype, is a controversial entity. Recent study suggested using 'non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP)' for these indolent carcinomas. We evaluated the impact of reclassification from non-invasive encapsulated FVPTCs (EFVPTCs) to NIFTPs in the diagnosis of thyroid nodules with architectural atypia. METHODS: We reviewed 1301 thyroid nodules with architectural atypia in core needle biopsy (CNB) specimens obtained from March 2012 to February 2013...

PURPOSE: Transanal minimally invasive surgery using single port instrumentation is now well described for the performance of total mesorectal excision with restorative colorectal/anal anastomosis most-often in conjunction with transabdominal multiport assistance. While non-restorative abdomino-endoscopic perineal excision of the anorectum is conceptually similar, it has been less detailed in the literature. METHODS: Consecutive patients undergoing non-restorative ano-proctectomy including a transperineal endoscopic component were analysed...

We encountered a rare case of metastatic brain tumors in the bilateral cerebellopontine angles. The patient was a 61-year-old man, who visited an otorhinolaryngology clinic with complaints of rapidly progressing bilateral hearing impairment and facial palsy. The patient was referred to our hospital because tumorous lesions were suspected in the bilateral cerebellopontine angles on brain magnetic resonance imaging. Regarding tumor markers, the patient's cancer antigen 19-9 and carcinoembryonic antigen levels were high, which suggested metastasis...

BACKGROUND AND PURPOSE: Although core needle biopsy was introduced as a diagnostic alternative to fine-needle aspiration, the utility and safety of core needle biopsy for thyroid nodules in a large population has yet to be studied comprehensively. We evaluate core needle biopsy yields on a large-scale basis to investigate its potential in the preliminary diagnosis of thyroid nodules. MATERIALS AND METHODS: Between March 2005 and December 2013, 2448 initially detected thyroid nodules from 2120 consecutive patients who underwent core needle biopsy were retrospectively evaluated...

We present a case report of a 61-year-old patient with acute pulmonary and cerebral infections with Aspergillus and Rhizopus. The only risk factor for invasive fungal disease was high-dose corticosteroids used to treat her chronic obstructive pulmonary disease exacerbation. She had rapid progression and succumbed to her infections within 2 weeks of diagnosis in spite of aggressive antifungal therapy and surgery. To the best of our knowledge, this is the first reported case of rapidly fatal dual infection with Aspergillus and Rhizopus Our case highlights the role of high-dose corticosteroids as a risk factor for invasive fungal disease in patients without traditional risk factors like haematological malignancies, solid organ transplantation or uncontrolled diabetes...

BACKGROUND: Malignancy is one of the most common long-term complications in renal transplant patients, often related to immunosuppressive treatment although other factors could be considered. Vitamin D plays an important role in reducing cancer risk. After kidney transplantation (KT), 25-hydroxyvitamin D (25OH-D, or calcidiol) insufficiency concerns >85%. The main aim of the present study was to determine the relationship between calcidiol blood levels and cancer development in KT recipients...

BACKGROUND: Staging of mediastinal lymph nodes in non-small cell lung cancer (NSCLC) is mandatory. The maximum Standard Uptake Value (SUVmax) obtained using F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) is the best non-invasive technique available for this evaluation, but its performance varies from center to center. The aim of the present study was to identify FDG-PET predictors of mediastinal malignancy that are able to minimize intercenter variability and improve the selection of subsequent staging procedures...

BRCA mutation carriers have a very high risk of breast and ovarian cancer by age 70, in the ranges 47%-66% and 40%-57%, respectively. Additionally, women with BRCA mutation-associated breast cancer also have an elevated risk of other or secondary malignancies. Fortunately, the breast and ovarian cancer outcome for BRCA1/2 mutation carriers is at least as good as for non-carriers with chemoprevention, prophylactic surgeries and appropriate use of therapies. Therefore, identification of those who might have a mutation is important so that genetic counseling, testing, screening and prevention strategies can be applied in a timely manner...

Importance: Management of cervical lymph node metastasis without a known primary tumor is a diagnostic and treatment challenge for head and neck oncologists. Identification of the occult mucosal primary tumor minimizes the morbidity of treatment. Objective: To analyze the role of transoral robotic surgery (TORS) in facilitating the identification of a primary tumor site for patients presenting with squamous cell carcinoma of unknown primary (CUP). In addition, we assessed treatment deintensification by determining the number of patients who did not undergo definitive radiation therapy and chemotherapy...

The vast majority of benign tumors of the cerebellopontine angle, temporal bone, and parotid gland can be successfully resected without permanent injury to the facial nerve. Malignant tumors or recurrent disease may require facial nerve sacrifice, especially if preoperative facial paresis is present. This article will present case examples of the various methods to reconstruct facial animation after lateral skull base resections that require sacrifice of cranial nerve VII, and the associated mimetic facial musculature...

Undifferentiated pleomorphic sarcoma, previously called malignant fibrous histiocytoma, usually arises in the extremities and retroperitoneum. Primary laryngeal undifferentiated pleomorphic sarcoma is very rare, with only 63 cases having been reported in the literature as of 2015. The disease has a poor prognosis because of problems with local recurrence and metastasis. Wide resection has been recommended as a treatment modality in previous reports. We report a case of undifferentiated pleomorphic sarcoma of the vocal fold in a 64-year-old man presenting with rapid growth...

Nowadays, surgery still remains the mainstay treatment for gastrointestinal stromal tumor (GIST). Nevertheless, some GIST patients have also experienced tumor recurrence/metastasis even with R0 resection. Meanwhile, the prognosis of GIST has been dramatically improved after targeted drug imatinib used in clinical practice for GIST, but tumor recurrence/metastasis still occurred in some patients with high-risk when adjuvant treatment course ended, as such, the 2008 modified NIH criterion, which is used to guide the adjuvant treatment of GIST, still has shortcomings...

BACKGROUND: Postoperative ileus (POI) is a major cause of morbidity, increased length of stay (LOS) and hospital cost after colorectal surgery. Alvimopan is a µ-opioid antagonist used to accelerate upper and lower gastrointestinal function after bowel resection. We hypothesized that alvimopan would reduce LOS in patients undergoing colorectal resection with stoma, a situation that has not been evaluated. METHODS: A retrospective review (2010-2015) identified 58 patients who underwent colorectal resection for benign or malignant disease with stoma creation and received alvimopan...

Background. The survival of patients with cutaneous malignant melanoma (MM) depends on multiple factors whose role is continuously updated, as the molecular mechanisms underlying the disease progression are understood. This study intended to assess whether the patient's gender and tumor location affect the disease outcome. Methods. Between 2008 and 2012, 155 patients with cutaneous MM underwent various types of surgeries in our clinic. Patients were staged according to the 2009 TNM classification. There were 90 women and 65 men...

Papillary thyroid carcinoma (PTC) is a type of well-differentiated thyroid cancer that accounts for the majority of thyroid malignancies. The prognosis of PTC is very good and distant metastases are rare, especially to the skull base. The authors report the case of a 47-year-old woman with biopsy-proven PTC treated with surgery and radiation therapy who presented with headache and diplopia after 5 years and was found to have clivus and cavernous sinus metastasis. Following radiation therapy for her skull base and cavernous sinus lesion, she subsequently developed sixth nerve ocular neuromyotonia...

Constrictive pericarditis (CP) is an uncommon post inflammatory disorder. It is described as pericardial thickening, myocardial constriction, and impaired diastolic filling. The most common etiologies are idiopathy, mediastinal radiotherapy, and prior cardiac surgery. Less common etiologies include viral infections, collagen vascular disorders, renal failure, sarcoidosis, tuberculosis, and blunt chest trauma. CP can less commonly be caused by malignancy. We report a very rare case of non-Hodgkin's lymphoma (NHL) presenting twice with attacks of decompensated heart failure...
