PURPOSE: Identification of clinicopathological factors predicting for a locoregional recurrence (LRR) after neoadjuvant chemotherapy (NAC) could help to decide on the optimal locoregional radiotherapy. The objective of this trial is to identify those factors in the context of a phase III trial (European Organisation for Research and Treatment of Cancer 10994). METHODS: Patients received NAC followed by surgery with or without radiotherapy. Radiotherapy was administered according to pre-specified guidelines...

The surgical risk factors and neuro-imaging characteristics associated with cerebellar mutism (CM) remain unclear and require further investigation. Therefore, we aimed to examine surgical and MRI findings associated with CM in children following posterior fossa tumor resection. Using our data registry, we retrospectively collected data from pediatric patients who acquired CM and were matched based on age and pathology type with individuals who did not acquire CM after posterior fossa surgery. The strength of association between surgical and MRI variables and CM were examined using odds ratios (ORs) and corresponding 95% confidence intervals (CIs)...

BACKGROUND: Ectopic pituitary adenomas (EPAs) are rare, and the suprasellar cistern seems to be the most common location. At this time, no detailed original classification, diagnosis, or treatment protocols for suprasellar pituitary adenomas (SPAs) have been described. CASE DESCRIPTION: A 19-year-old man showed visual disturbances and lack of libido for 3 years, he suffered a sharp decline in vision with only light perception in the last week. Magnetic resonance imaging scans revealed a large suprasellar cystic lesion with a normal pituitary in the sella turcica...

OBJECTIVES: Women seeking sterilization are usually parous and have no major complains, such as pelvic pain. This could be a good model to indirectly assess the prevalence of endometriosis in the general population. Prevalence of endometriosis in women undergoing tubal sterilization by laparoscopy has been assessed in 17 published reports. Results indicate a surprising wide variation of prevalence of endometriosis, ranging from 1.4% to 43.3 %. This clinical study describes the prevalence and clinical presentations of endometriosis identified at interval laparoscopic tubal sterilization, as a close representation of endometriosis in general population...

BACKGROUND: The new American Joint Committee on Cancer eighth edition (AJCC8) staging is the first to describe separate clinical and pathology staging systems, but still has low performance to predict prognosis in patients with oesophageal/gastroesophageal junction (O/GOJ) adenocarcinoma, who are candidates for surgery. Recent studies have demonstrated that O/GOJ cancer patients with 18F-fluorodeoxyglucose (FDG) avid regional lymph nodes (RLNs) may have poor prognosis. The aim of our study was to examine whether the baseline assessment of the FDG uptake of RLN improves the prognostic accuracy of the new AJCC8 staging...

BACKGROUND: A transoral approach has been experimentally introduced to the field of thyroid surgery and several groups in Asia have recently used the technique to treat patients. We performed transoral endoscopic thyroidectomies on patients with thyroid cancer or a benign tumor. METHODS: We reviewed the medical records of patients who underwent transoral endoscopic thyroid surgery between July 2016 and January 2017. A midline incision was made in the vestibule, and a 10 mm cannula was placed; then, the working space was widened by insufflating CO2 at a pressure of 5-6 mmHg...

Chondrosarcoma is a malignant hyaline cartilage forming tumor. It is a rare pathology, with an estimated incidence of one in 200 000 individuals per year. It appears in two forms: primary, representing 90% of all cases and secondary emergence that develops on preexistent lesions. Primary chondrosarcomas are uncommon in the hand, with a frequency of only 1.5-3.2% of all chondrosarcomas. In conventional chondrosarcoma (cCS), the histological malignancy grading represents the main prognostic factor for surgical planning and prognosis...

Small and deeply seated pure ground-glass opacity (GGO) pulmonary nodules (PNs) are not discernible during video-assisted thoracoscopic surgery (VATS). Moreover, pathologists have difficulty in detecting these nodules due to insufficient localization. We percutaneously injected a mixture of lipiodol and India ink during preoperative CT-guided localization in a 52-year-old female patient presenting with a pure GGO PN. A black-pigmented tattoo lesion was clearly identified, and thoracoscopic wedge resection was performed without difficulty...
