Gardner syndrome (GS) is a form of familial adenomatous polyposis (FAP) and is characterized by colonic polyposis, osteomas, and soft-tissue tumors. Desmoid tumors (DT) are lesions of mesenchymal origin and are an extra-colonic manifestation of GS. Gardner-associated fibroma (GAF) is considered to be a benign soft-tissue lesion related to DT and FAP. Here we present a case of an 18-year-old female patient with a huge lump in her right thoracic cavity and another lump located in her left lumbar muscles who was diagnosed with GS through a colonoscopy and through adenomatous polyposis coli (APC) gene mutation detection. The patient underwent a surgical resection of the right thoracic tumor. Three months later, the left waist lump underwent medical treatment with tamoxifen and celecoxib and was monitored using computed tomography (CT). Subsequently, colonoscopy screening was performed annually to prevent colorectal cancer. GAF is frequent in GS, and such a huge GAP in the thorax is very rare, with few cases reported in the literature. Patients with GS must be closely monitored, and clinical and imaging examinations must be performed to detect any signs of tumors.Pilomatrix carcinoma (PC) is a rare skin adnexal neoplasm derived from piliferous follicles, usually occurring in the head and neck region. An optimal treatment for PC has not yet been established, while surgery with wide margins is recommended, with radiation therapy (RT) and chemotherapy improving the curative effect. Location of this tumor in the breast is exceedingly rare, especially for a male. We now report an unusual case of a 53-year-old male who presented with 2 palpable masses in the right breast, which had been removed surgically about 4 and a half years prior, but recurred after 7 months. Ultrasonography revealed 2 irregular low-echo masses with a well-defined boundary, and computed tomography (CT) showed 2 soft tissue masses in subcutaneous tissue of the right breast. The tumors were completely removed without RT and chemotherapy. After about 4 years' follow-up, the patient remains free of local recurrence and metastasis. To the best of our knowledge, only 2 cases of PC in the breast region have been reported, but were female.Epithelioid sarcoma (ES) is a rare histological type of soft tissue sarcoma presenting as a subcutaneous or deep dermal mass in the distal extremities of young adults. Recently, a more aggressive, so called 'proximal-type' ES has been described. The literature is limited on the clinical features and management of ES originating in the head and neck area. We here report a case of 16-year-old female who initially presented with progressive swelling and pain in the left cheek. On physical and radiographic examination, a malignant neoplasm was found in the left maxillary sinus with bony invasion. The definite diagnosis of proximal-type ES was based on the pathological and immunohistochemical characteristics. A subtotal maxillectomy with wide margins was performed on this patient. The patient survived uneventfully for three years. This is the first report of a proximal-type ES found in the maxillary sinus.Desbuquois dysplasia (DBQD) is a severe chondrodysplasia characterized by short stature, retarded development, multiple joint dislocations, and a distinct radiological appearance of the proximal femur. Pathogenic variants in the calcium-activated nucleotidase 1 (CANT1) or xylosyltransferase 1 (XYLT1) gene have been previously reported to cause DBQD. Here we present a 12-year-old boy manifesting the typical features of DBQD type 1 caused by a homozygous intronic variant c.836-9G>A of CANT1. To our knowledge, this is the first DBQD case described in China revealing that a CANT1 variant was also responsible for DBQD in the Chinese population and further emphasizing the role of CANT1 variants in the etiology of DBQD type 1. Our finding provides certainty for the DBQD clinical diagnosis of this patient and expands the spectrum of known DBQD genetic risk factors. On the basis of this study, amniocentesis-based prenatal diagnosis or preimplantation genetic diagnosis (PGD)-based assisted reproduction could be a helpful aristogenesis strategy to avoid the birth of a DBQD affected child.
To investigate the influence of PD-L1 polymorphisms on the susceptibility of non-small-cell lung cancer (NSCLC) and the prognosis of NSCLC patients who undergo platinum-based chemotherapy.
9 single nucleotide polymorphisms (SNPs) in the PD-L1 gene, including rs822336 (G>C), rs822337 (T>A), rs10815225 (G>C), rs7866740 (C>G), rs866066 (C>T), rs822338 (C>T), rs2890657 (C>G), rs2890658 (C>A), and rs229136 (C>G) were selected for this study. Genotyping was performed in 281 advanced NSCLC patients and 251 healthy volunteers using the matrix assisted laser desorption ionization time-of-flight (MALDI-TOF) method.
The G allele of PD-L1 rs7866740 was significantly related to the risk of NSCLC. compound 78c research buy Compared with the C allele, the G allele an increase the risk of NSCLC (OR=3.532, 95% CI 1.232-10.129,
=0.001). In terms of the clinical outcomes, PD-L1 rs2890658 C>A was significantly associated with both a worse progression-free survival (adjusted HR=1.367, 95% CI=1.0-1.8,
=0.038) and a worse overall survival (adjusted HR=1.402, 95% CI=1.0-1.9,
=0.026) of NSCLC patients. PD-L1 rs822336 G>C was significantly related to a worse overall survival (adjusted HR=1.393, 95% CI=1.1-1.8,
=0.021).
PD-L1 rs7866740 C>G may play a role in the pathogenesis of NSCLC. PD-L1 rs2890658 C>A and rs822336 G>C are related to the prognoses of patients receiving platinum-based chemotherapy.
C are related to the prognoses of patients receiving platinum-based chemotherapy.
Benign prostatic hyperplasia (BPH) is an age-related disease, occurring in >70% of men of age >60. Because telomeres and telomerase play a key role in aging and age-related diseases, and certain telomerase gene single nucleotide polymorphisms (SNPs) are shown to be associated with the susceptibility to age-related diseases, we wanted to determine the relationship between BPH and leukocyte telomere length (LTL) and telomere length-related single nucleotide polymorphisms (SNPs) of the telomerase holoenzyme genes.
Peripheral blood was collected from both BPH patients and age-matched healthy male controls and genomic DNA was extracted. rs2736100 and rs2736098 at the
and rs12696304 at the
locus were analysed using pre-designed TaqMan SNP genotyping assay kits. LTL was determined using qPCR.
Patients with BPH had significantly shorter LTL (1.231 ± 0.532 vs 0.899 ± 0.322, P < 0.001). The genotyping results show similar frequencies in rs2736100, rs2736098 and rs12696304 between healthy and BPH individuals.
