The aim of the present study was to compare the recovery of sufentanil and remifentanil anesthesia by target-controlled infusion (TCI) in elderly patients with laparoscopic-assisted radical resection of colorectal cancer. The effect of anesthesia on patient stress response and cellular immune function was also observed. Elderly patients (n=192) who underwent laparoscopic radical resection of colorectal cancer between July 2014 and October 2015 were randomly divided into the sufentanil and remifentanil groups (n=96 per group). ⋯ The adverse reactions rate during anesthesia of the remifentanil group was significantly higher than that of the sufentanil group. In conclusion, sufentanil- and remifentanil-based anesthesia with TCI has certain advantages, including improved recovery effect, less stress response, less inhibition of cellular immunity and fewer adverse reactions. It has the potential to become the first choice of anesthetic in the clinic for elderly patients who undergo laparoscopic radical resection for colorectal cancer.

The present study reports a case of low-grade fibromyxoid sarcoma that occurred in a 62-year-old woman 9 years subsequent to whole breast irradiation for a carcinoma of the left breast, and 18 years following chemotherapy and radiotherapy (RT) for non-Hodgkin's lymphoma (NHL; diagnosed at the age of 43). The patient was 53 years of age when a cT2N0M0 stage IIA breast tumor was identified and excised. A 2.5 cm diameter nodule with dimpling in the upper-outer region of the left breast was detected. ⋯ The patient remained clinically stable for 4 years thereafter, until 2008 when the patient experienced a local relapse and underwent surgery. On 19 October 2011, the patient succumbed to RIS. The current study suggests that the RT history of a patient requires consideration due to the possible development of RIS, including the development of a low-grade fibromyxoid sarcoma, which may lead to a poor prognosis.

Langerhans' cell histiocytosis (LCH) is a rare disease with a wide spectrum of clinical manifestations, varying from an isolated lesion to systemic involvement. The etiology of this disease remains to be elucidated. ⋯ Magnetic resonance imaging revealed a heterogeneously contrast-enhanced mass near the left temporal pole, which eroded into the patient's left orbit and maxillary sinus. The lesion was totally excised and confirmed to be LCH through biopsy.

The present study aimed to investigate the genes and signaling pathways associated with squamous cell carcinoma (SCC) by bioinformatics analysis. For this purpose, the GSE2503 was downloaded from the Gene Expression Omnibus database, and the differentially expressed genes (DEGs) between 6 normal skin and 5 SCC samples were analyzed using the Linear Models for Microarray Data package. Gene Ontology (GO) and pathway enrichment analysis of DEGs were performed, followed by functional annotation and construction of a protein-protein interaction (PPI) network. ⋯ Integrin alpha (ITGA)6 and 2 were enriched in several pathways, including focal adhesion and extracellular matrix-receptor interaction. DEGs of SCC were primarily enriched in pathways associated with cancer and cell adhesion. Therefore, DEGs such as IL8, MMP1, HIF1A, ITGA6 and ITGA2 may be potential targets for the diagnosis and treatment of SCC.

A giant-cell tumor of the bone (GCTB) is a benign but locally aggressive bone tumor. Recently, the receptor activator of nuclear factor κB (RANK) ligand inhibitor, denosumab, has demonstrated activity against giant-cell tumors. The current study reports a case of a sacral GCTB with lung metastasis. ⋯ The specimen from the pulmonary nodule exhibited similar findings to the surgical specimen. It was reported that denosumab treatment was able to reduce the number of giant cells and RANK-positive stromal cells, and cause the formation of new bone in the primary lesion. The present study reports the first case to demonstrate the efficiency of denosumab in treating pulmonary metastasis of GCTB.
