Serum Enzymes and Pathologic Complete Response to the Addition of Targeted Therapy in Neoadjuvant Chemotherapy for HER2-Positive Breast Cancer Patients.

Background: This study investigated the association between circulating alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH), and gamma-glutamyltransferase (GGT) and the pathologic complete response (pCR) in patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer receiving neoadjuvant chemotherapy with trastuzumab (H) and pertuzumab (P).

Methods: Data were collected from 290 patients with HER2-positive breast cancer at Sichuan Cancer Hospital between August 2019 and August 2023. Blood samples were collected to assess the serum enzyme levels, including ALT, AST, CK, LDH, and GGT.

Association of CYP7B1 expression with the prognosis of endometrial cancer: a retrospective study.

Background: Endometrial cancer (EC) tissues express CYP7B1, but its association with prognosis needs to be investigated.

Methods: Immunohistochemistry and image analysis software were used to assess CYP7B1 protein expression in paraffin-embedded endometrial tumor sections. Associations between CYP7B1 and clinical factors were tested with the Wilcoxon rank-sum test.

Association between pathologic complete response and biochemical indicators after neoadjuvant therapy for HER2-positive breast cancer.

Purpose: This study investigated the changes in the fasting blood glucose (FBG), fasting triglyceride (FTG), and fasting total cholesterol (FTC) levels during neoadjuvant therapy (NAT) for human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC) and the association with pathologic complete response (pCR).

Methods: Relevant data from Sichuan Cancer Hospital from June 2019 to June 2022 were collected and analyzed, and FBG, FTG, and FTC were divided into baseline, change, and process groups, which were grouped to analyze the changes after receiving NAT and the association with pCR.

Results: In the estrogen receptor (ER)-negative subgroup, patients with low levels of FTG in the process group were more likely to achieve pCR compared to high levels, and in the progesterone receptor (PR)-negative subgroup, patients with lower FTG compared to higher FTG after receiving NAT was more likely to achieve pCR.

Differences between the efficacy of HER2(2+)/FISH-positive and HER2(3+) in breast cancer during dual-target neoadjuvant therapy.

Introduction: This study investigated the differences in efficacy between IHC(2+)/FISH-positive and IHC(3+) in HER2-positive breast cancer (BC) during neoadjuvant chemotherapy (NAC) combined with trastuzumab and pertuzumab. The research also aimed to provide insight into treatment strategies for clinical HER2(2+)/FISH-positive and HER2(3+) BC.

Materials And Methods: A retrospective analysis was performed on the clinical and pathological data of patients with confirmed diagnoses of invasive BC treated via combined NAC and dual-target therapy who underwent surgery at the Breast Surgery Center of Sichuan Cancer Hospital between June 2019 and June 2022.

Timely assessment of 5-year relative survival for patients with thyroid cancer from Taizhou, eastern China: a period analysis.

Background: While timely assessment of long-term survival in thyroid cancer patients is critical for assessing early detection and screening programs for thyroid cancer, those data are sorely lacking in China. We aimed to timely and accurately assess the long-term survival of thyroid cancer patients in eastern China.

Methods: Patients diagnosed with thyroid cancer during 2004-2018 from four cancer registries in Taizhou, eastern China were included.

Use of period analysis to timely assess 5-year relative survival for breast cancer patients from Taizhou, Eastern China.

Objectives: While timely assessment of long-term survival for patients with breast cancer is essential for evaluation on early detection and screening programs, those data are extremely scant in China. We aimed to derive most up-to-date survival estimates and to predict future survival using the cancer registry data from Taizhou city, Eastern China.

Methods: Patients diagnosed with breast cancer during 2004-2018 from four cancer registries with high-quality data from Taizhou, Eastern China were included.

The comparative burden of brain and central nervous system cancers from 1990 to 2019 between China and the United States and predicting the future burden.

Background: Brain and central nervous system (CNS) cancers represent a major source of cancer burden in China and the United States. Comparing the two countries' epidemiological features for brain and CNS cancers can help plan interventions and draw lessons.

Methods: Data were extracted from the Global Burden of Disease repository.

Sinomenine Inhibits Vasculogenic Mimicry and Migration of Breast Cancer Side Population Cells via Regulating miR-340-5p/SIAH2 Axis.

Hypoxia and its induced vasculogenic mimicry (VM) formation, which both closely related with stem-like side population (SP) cells, are the main culprits leading to tumor invasion and metastasis. Sinomenine exhibits excellent anticancer activity in breast cancer, but whether and how it affects hypoxia-triggered VM formation in breast cancer SP cells remains unclear. In this study, breast cancer SP cells were sorted from MDA-MB-231 cells and cultured with sinomenine under hypoxic conditions.

Myocardin inhibits estrogen receptor alpha-mediated proliferation of human breast cancer MCF-7 cells via regulating MicroRNA expression.

Myocardin is frequently repressed during human malignant transformation, and restoration of myocardin expression in sarcoma cells contributes to the inhibition of malignant growth. However, its role in breast carcinoma has barely been addressed. Here, we reported that myocardin could inhibit the proliferation of MCF-7 cells.

miR‑96 functions as a tumor suppressor gene by targeting NUAK1 in pancreatic cancer.

microRNA-96 (miR-96) is known to be downregulated in pancreatic cancer. The overexpression of miR-96 in MIA PaCa-2 pancreatic cancer cells has been shown to inhibit cell proliferation, migration and invasion; however, the mechanisms involved have not yet been fully elucidated. Novel (nua) kinase family 1 (NUAK1) functions as an oncogene in non‑small cell lung cancer (NSCLC), melanoma, glioma, breast cancer, hepatocellular carcinoma and pancreatic cancer.

miR-219 inhibits the proliferation, migration and invasion of medulloblastoma cells by targeting CD164.

It is known that microRNA-219 (miR-219) expression is downregulated in medulloblastoma. In the present study, we investigated the expression, targets and functional effects of miR-219 in D283-MED medulloblastoma cells. We first demonstrated that miR-219 not only inhibits proliferation, but also suppresses the invasion and migration of D283-MED cells.

Estrogen receptor α mediates proliferation of breast cancer MCF-7 cells via a p21/PCNA/E2F1-dependent pathway.

High expression of estrogen receptor α (ERα) is associated with a poor prognosis that correlates closely with cellular proliferation in breast cancer. However, the exact molecular mechanism by which ERα controls breast cancer cell proliferation is not clear. Here we report that ERα regulates the cell cycle by suppressing p53/p21 and up-regulating proliferating cell nuclear antigen (PCNA) and proliferation-related Ki-67 antigen (Ki-67) to promote proliferation of MCF-7 cells.

Electroless deposition of platinum nanoparticles in room-temperature ionic liquids.

The electroless deposition of Pt nanoparticles (Pt-NPs) could be carried out by dissolving potassium tetrachloroplatinate(II) (K2[PtCl4]) in 1-ethyl-3-methylimidazolium (EMI(+)) room-temperature ionic liquids (RTILs) containing bis(trifluoromethylsulfonyl) imide (NTf2(-)) or tetrafluoroborate (BF4(-)) anion and small cations, such as H(+), K(+), and Li(+). In this case, no deposition of Pt-NPs occurred in RTILs without such small cations. The formation of Pt-NPs was only observed in RTILs containing trifluoromethanesulfonimide (HNTf2) and protons at high temperature (≥80 °C) when potassium hexachloroplatinate(IV) (K2[PtCl6]) was dissolved in the RTILs.
