  • * It found that tamoxifen significantly reduces the risk of cancer recurrence compared to AIs, especially in stage 2 cancer cases, while stage 1 showed no difference in efficacy.
  • * The conclusion emphasizes the potential of tamoxifen for improving outcomes and highlights the importance of adherence to treatment to minimize recurrence in affected patients.

Invasive lobular cancer (ILC) of the breast is the second most common type of invasive breast cancer. Clinical determination of the growth pattern of ILC of the breast is difficult. Furthermore, the ILC of the breast has a unique metastatic pattern that involves gastrointestinal and peritoneal sites.

Inspired by Connected-UNets, this study proposes a deep learning model, called Connected-SegNets, for breast tumor segmentation from X-ray images. In the proposed model, two SegNet architectures are connected with skip connections between their layers. Moreover, the cross-entropy loss function of the original SegNet has been replaced by the intersection over union (IoU) loss function in order to make the proposed model more robust against noise during the training process.

Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Patients with inflammatory bowel disease (IBD) have a high risk of developing CRC. Inflammatory cytokines are regulated by complex gene networks and regulatory RNAs, especially microRNAs.

Background: The multinational BREAKOUT study (NCT03078036) sought to determine the prevalence of germline BRCA1/2 (gBRCA1/2) and somatic BRCA1/2 (sBRCA1/2) mutations and mutations in other homologous recombination repair (HRR) genes in women with HER2-negative metastatic breast cancer (MBC) starting first-line chemotherapy.

Methods: Genetic testing for gBRCA, sBRCA, and HRR gene mutations was performed in patients who started first-line chemotherapy for MBC in the last 90 days (341 patients across 14 countries) who were not selected based on risk factors for gBRCA mutations. We report data from the Asian cohort, which included patients in Japan (7 sites), South Korea (10 sites), and Taiwan (8 sites).

Article Synopsis
  • En bloc right hemicolectomy plus pancreaticoduodenectomy (cPD) is a surgical procedure for advanced colon cancer affecting the duodenum or pancreatic head, often performed in emergency situations where patients exhibit acute abdominal symptoms.
  • A study retrospectively evaluated 30 patients with locally advanced right colon cancer who underwent cPD, with 11 of those surgeries performed under emergency conditions due to critical issues like bowel obstruction and perforation.
  • Findings showed that while emergency surgery had a higher complication rate (63.6%) compared to non-emergency (42.1%), both groups had similar long-term outcomes without any fatalities related to the cPD procedure.

As research progressed, the recommended duration of endocrine therapy for breast cancer patients has been extended from 5 to 10 years. This study aimed to investigate how the duration of endocrine medication and therapy affect survival rate in the real world. By using the National Health Insurance Research Database (NHIRD), this study examined 1002 breast cancer patients newly diagnosed between 2000 and 2005 as research subjects, and conducted follow-up until 2013.

The unregulated activation of STAT3 has been demonstrated to occur in many cancers and enhances tumour growth, migration, and invasion. Stimulation by cytokines, growth factors, and hormones triggers this activation by phosphorylating STAT3 at tyrosine 705. Novel imidazopyridine compounds were synthesized to evaluate the inhibition of STAT3 at Y705.

Cervical cancer is one of the most common cancers in women worldwide and it is a prominent cause of cancer mortality. Curcumin is one of the major compounds from Turmeric and has been shown to induce cytotoxic cell death in human cervical cancer cells. However, there is no study to show curcumin induced DNA damage action via the effect on the DNA damage and repair protein in cervical cancer cells in detail.

Agaricus blazei Murill (AbM) is traditionally used against a wide range of conditions such as ulcerative colitis, Crohn's disease, foot-and-mouth disease and chronic hepatitis C infection. In this study, we evaluated the immunomodulatory effects of AbM. For the non-specific immune response experiments, a total of 40 female BALB/c mice were divided into control (group 1) and experimental (groups 2-4) groups of 10 animals each.

Antrodia cinnamomea is a natural component of some herbal medicines used for treatment of abdominal pain, hypertension and hepatocellular carcinoma in Taiwan and other countries. Subchronic oral toxicity studies of A. cinnamomea extracts in male and female BALB/c mice were performed to evaluate its safety.

A number of experiments have demonstrated that benzyl-isothiocyanate (BITC) induces cytotoxic cell death through the induction of apoptosis in various human cancer cell lines. In the present study, we investigated the effects of BITC on the growth of A375.S2 cell xenograft tumors in nude BALB/c mice in vivo.

Compound C, a well-known inhibitor of the intracellular energy sensor AMP-activated protein kinase (AMPK), has been reported to cause apoptotic cell death in myeloma, breast cancer cells and glioma cells. In this study, we have demonstrated that compound C not only induced autophagy in all tested skin cancer cell lines but also caused more apoptosis in p53 wildtype skin cancer cells than in p53-mutant skin cancer cells. Compound C can induce upregulation, phosphorylation and nuclear translocalization of the p53 protein and upregulate expression of p53 target genes in wildtype p53-expressing skin basal cell carcinoma (BCC) cells.
