    55; 95% CI 1.83, 6.86; P=0.0002; I²=0). FP was obviously associated with the occurrence of POPF (OR=3.75; 95% CI 1.64, 8.58; P=0.002; I²=78).

    FP is closely associated with the development of POPF, and the early identification of these high-risk patients can help to reduce the incidence of POPF.

    It has been debated whether familial non-medullary thyroid carcinoma (FNMTC) is more aggressive and has a worse prognosis than sporadic non-medullary thyroid carcinoma (SNMTC). Our aim was to compare the invasiveness and prognosis of FNMTC and SNMTC by their biological behavior and molecular changes.

    Our group mainly compared 106 patients with FNMTC whom have complete clinicopathological data during 2011-2019 in West China Hospital, Sichuan University, and 212 randomly selected cases with SNMTC were included to compare their biological behavior, recurrence and mortality, and molecular expression of

    V600E and

    promoter. At the same time, FNMTC cases were divided into four subgroups, namely, two affected members group, three or more affected members, parent/offspring group, and sibling group, and they were compared with SNMTC separately to analyze the difference in their invasiveness and prognosis.

    We found that the mean tumor size of FNMTC (0.96 ± 0.53cm) was smaller than that of SNMTC (1.15 ± 0.72 s and prognosis between FNMTC and SNMTC by biological behavior, patient survival, and molecular level comparison.

    The preoperative systemic immune-inflammation index (SII) is correlated with prognosis in several malignancies. The aim of this study was to investigate the prognosis value of SII in patients with resected breast cancer.

    A total of 784 breast cancer patients who underwent surgical resection were consecutively investigated. The optimal cutoff value of SII was evaluated using the receiver operating characteristic (ROC) curve. The collection of SII with clinicopathological characteristic and prognosis was further evaluated.

    The optimal cutoff value for SII in the prediction of survival was 514 according to ROC curve analysis. A high SII was significantly correlated with younger age (

    = 0.037), PR status (

    < 0.001), and HER2 status (

    = 0.035). Univariate analysis revealed that SII (

    < 0.001), T-stage (

    < 0.001), lymph node involvement post-surgery (

    = 0.024), and histological grade (

    < 0.001) were significantly related to DFS, and SII (

    < 0.001), T-stage (

    = 0.003), lymph node involvement post-surgery (

    = 0.006), and histological grade (

    < 0.001) were significantly associated with OS. In multivariate analysis, a high SII was an independent worse prognostic factor for DFS (HR, 4.530; 95% CI, 3.279-6.258;

    < 0.001) and OS (HR, 3.825; 95% CI, 2.594-5.640;

    < 0.001) in all the enrolled patients. Furthermore, subgroup analysis of molecular subtype revealed that SII was significantly associated with prognosis in all subtypes.

    Preoperative SII is a simple and useful prognostic factor for predicting long-term outcomes for breast cancer patients undergoing surgery.

Chest CT showed large mixed density shadow of anterior mediastinum, multiple flaky fat density shadow, left lower lung compression, atelectasis, partial compression of right lung and obvious heart pressure. The patient’s symptoms are caused by the compression of the heart and lung by the mediastinal mass. The results of routine examination were normal. After excluding surgical contraindications, the patient underwent resection of a huge mediastinal tumor before median thoracotomy. The operation was smooth and the intraoperative vital signs were stable. The symptoms of chest tightness and shortness of breath disappeared after operation. The size of the tumor tissue removed after operation was about 45×30×25 cm3 and the weight was about 3.7 kg. The pathological diagnosis was thymolipoma. Postoperative reexamination of chest CT showed that the heart and lungs returned to the normal position. In this case, the operation is effective for large thymic tumors, and the symptoms of the patients are significantly relieved. Early diagnosis and surgical treatment are the key to improve the prognosis of patients. In this study, we reported a successful removal of a giant thymolipoma with complete disappearance of symptoms and no serious complications such as myasthenia gravis, aplastic anemia, and vitamin B12 deficiency.Cervical spondylotic myelopathy (CSM) is the most common disease of the cervical spinal cord in patients older than 55 and is characterized by an initial asymptomatic period followed by progressive neurological deficit from degenerative changes of the cervical vertebrae. These changes cause compression and vascular compromise to the cervical spinal cord. Because there are no pathognomonic symptoms, its diagnosis is commonly delayed. Herein we report the first case of the use of IONM during a transabdominal adrenalectomy in a patient with CSM, which prevented an iatrogenic spinal cord injury (SCI). The patient is a 74-year-old male with what was proven later as cervical spinal stenosis who presented for robotic-assisted transabdominal adrenalectomy. When positioned supine on the operating table, he exhibited upper and lower extremity neurological symptoms, prompting awake fiberoptic intubation and the use of IONM secondary to suspicion for CSM. After being positioned into lateral decubitus, IONM showed a loss of transcranial motor evoked potentials (TcMEP) and attenuated somatosensory evoked potentials (SSEP) from the right lower extremities and the procedure was aborted and the patient returned supine. TcMEPs returned to baseline, but SSEPs remained attenuated. The patient exhibited normal movement and sensation in post-anesthesia care. A high index of suspicion for CSM is required for older patients, as early diagnosis allows for spinal surgery treatment before acute worsening during anesthesia or non-spinal surgery. Furthermore, a low threshold for the use of IONM in patients with a high likelihood of CSM who require a non-spinal surgery can successfully prevent iatrogenic SCI.Tall cell carcinoma with reversed polarity (TCCRP) is an extremely rare type of invasive breast cancer with only 17 literatures and 75 cases reported. Knowledge on TCCRP is still scanty. The present study reported 2 cases of TCCRP, analyzed their clinicopathological characteristics, and used whole exome sequencing to perform genetic testing. Both two cases were proved to have typical clinicopathological manifestations (solid and papillary architectures lined by tall columnar cells with nuclei displaying “reverse polarization”) and hotspot mutations (IDH2 and PIK3CA mutations) of TCCRP. Zn-C3 nmr Furthermore, positive expression of TTF-1 was found in a small number of tumor cells nuclei and normal ductal epithelial cells, while the negative rate of TTF-1 in previous case reports was 100%. Attention should be paid in core needle biopsy to avoid misdiagnosis. In addition, this article also reviewed all previous cases and demonstrated that the positive expression of calretinin might have an indicative significance for TCCRP, which could be used as one of the auxiliary diagnosis tools. The diagnosis of TCCRP requires comprehensive analysis of clinical pathology and genetic testing results. There is no clear treatment standard for TCCRP currently, further research should be reported to characterize and deeply investigate the diagnosis and treatment criteria of TCCRP.While the incidence of metastatic breast cancer tumors in the thyroid gland is extremely rare, invasive micropapillary carcinoma (IMPC) of the breast metastasizing to the thyroid gland is even rarer. There are no known reported cases in which both invasive ductal carcinoma-no special type (IDC-NST) and IMPC existed in the breast tissue and where only the latter metastasized into the thyroid gland. This report details the case of a 59-year-old Chinese woman who was first diagnosed with grade 2 IDC-NST of the breast with involvement of 6 axillary lymph nodes in 2015. However, 5 years later, blood tests revealed increased tumor markers. Imaging revealed multiple solid nodules in both sides of the thyroid gland. Total thyroidectomy and bilateral cervical lymph node dissection were performed; the findings showed both IDC-NST and IMPC in the lymph nodes, but only the latter in the thyroid gland. Immunohistochemically, these tumor cells were positive for estrogen receptor (ER), progesterone receptor (PR), GATA binding protein 3 (GATA3), and mammaglobin, but negative for thyroglobulin (TG) and thyroid transcription factor-1 (TTF-1). Ultimately, the patient was diagnosed as having mixed breast cancer with metastatic IMPC in the thyroid gland, and chemotherapy was continued. Apart from the possibility of IDC-NST in breast tissue metastasizing to the thyroid, metastasis of IMPC of the breast must also be taken into consideration, especially when the patient has a history of breast cancer and thyroid nodules. Accurate diagnosis of metastatic breast carcinoma is vital for precise treatment and can improve the prognosis of patients.

    This study aimed to provide an extensive overview of clinical and pathological findings along with various therapeutic options analyzing in addiction, retrospectively, the surgical outcomes of a single center cohort.

    Thymic neoplasms are rare thoracic tumors which commonly are located in the anterior mediastinum and are associated with a wide spectrum of clinical presentations. They may run an indolent course or could present a very aggressive biologic progression with infiltration of mediastinal structures and presence of distant metastases. The pathogenesis of these tumors is so far not completely clear. Several treatment modalities in a multidisciplinary setting have to be considered in order to provide the best treatment for patients affected by thymic tumors.

    We conducted a retrospective cohort analysis of all patients who underwent surgery due to thymic tumor in a university hospital located in Switzerland (Bern University Hospital) and then we performed a narrative review of the English literature using PubMed, Embase, Cochrane Database of Systematic Reviews and Scopus.

    Minimally invasive techniques play an important role in the treatment of thymic tumors. A careful patients selection in a multidisciplinary setting is mandatory in order to offer the best treatment for patients affected by thymic tumors.

    Deltex 1 (

    ) is a single transmembrane protein with ubiquitin E3 ligase activity which has been found to play a role in the development of several cancers. We aimed to investigate the associations between

    and breast cancer (BC).

    We explored the roles and mechanisms of

    in BC by using BC cell lines

    . Levels of

    in serum and tissues were determined in 316 patients with BC, 102 patients with fibroadenoma, and 113 healthy controls by immunohistochemistry (IHC) and reverse transcription-polymerase chain reaction (RT-PCR). The associations between

    and clinical characteristics of BC were analyzed using multivariate analysis and Cox regression survival analysis.

    Lower levels of

    promoted BC cell proliferation, migration, and invasion. The cell growth and survival of BC might be regulated by DTX1 via the Notch signaling pathway. Levels of

    in BC tissues were lower compared to fibroadenoma tissues and peri-neoplastic breast tissues (P<0.01). A lower level of

    was shown to be associated with advanced tumor grade (P=0.
