Spica Prunellae Extract Enhances Fluorouracil Sensitivity of 5-Fluorouracil-Resistant Human Colon Carcinoma HCT-8/5-FU Cells via TOP2 α and miR-494.

In this study, we explored the mechanism of 5-FU resistance by bioinformatics analysis of the NCBI public dataset series GSE81005. Fifteen hub genes were screened out of 582 different expressed genes. Modules of the hub genes in protein-protein interaction networks gathered to TOP2α showed a decrease in HCT-8 cells but an increase in 5-FU-resistant HCT-8/5-FU cells with 5-FU exposure. Downregulation of TOP2α with siRNA or miR-494 transfection resulted in an increase of cytotoxicity and decrease of cell colonies to 5-FU for HCT-8/5-FU cells. Moreover, we found that an ethanol extract of Spica Prunellae (EESP), which is a traditional Chinese medicine with clinically beneficial effects in various cancers, was able to enhance the sensitivity of 5-FU in HCT-8/5-FU cells and partly reverse the 5-FU resistance effect. It significantly helped suppress cell growth and induced cell apoptosis in HCT-8/5-FU cells with the expression of TOP2α being significantly suppressed, which increased by 5-FU. Consistently, miR-494, which reportedly regulates TOP2α, exhibited reverse trends in EESP/5-FU combination treatment. These results suggested that Spica Prunellae may be beneficial in the treatment of 5-FU-resistant CRC patients. PMID: 31662984 [PubMed - in process]

CONCLUSION: Although classically, majority of studies have shown oncogenic roles of nucleoporins as genetic fusion partners in several types of leukemia, emerging evidence suggests that nucleoporins also modulate many cellular signaling pathways that are associated with several major non-hematological malignancies, such as carcinomas of skin, breast, lung, prostate and colon. Hence, nucleoporins are emerging as novel therapeutic targets in human tumors. PMID: 31654122 [PubMed - indexed for MEDLINE]

ConclusionTo optimize targeting and visualization of the surgical field in right pelvic sidewall/paracolic gutter, robotic arms can be placed in a straight line from above the pubic symphysis extending to the left subcostal line and between the midline vertical and midclavicular lines. Robotic tumor debulking should be considered in selected patients with recurrent ovarian cancer who present with oligo-metastatic disease, in the absence of carcinomatosis.

We reported a case of a 66-year-old man after surgery, chemotherapy, and radiation therapy for colon cancer. Two months after these therapies, the patient complained of nonproductive cough for 1 week. Diagnoses: 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) scanning revealed increased FDG uptake along the thickened bronchovascular bundles, in bilaterally scattered ground-glass opacities and in mediastinal lymphadenopathy. The transbronchial biopsy and pathological study confirmed the diagnosis of PLC. Interventions: Antineoplastic treatment (cetuximab) were administered afte...

ConclusionsDevelopment of PD-1 B-cell vaccine was successful, showing no evidence of toxicity or autoimmunity in mice, rabbits and beagle dogs. The combination vaccines could provide improved outcomes in early stage disease sparing patients the toxicity of chemotherapy. A phase 1 clinical trial with the PD-1 vaccine is under planning.Legal entity responsible for the studyThe authors.FundingNIH; Imugene.DisclosureAll authors have declared no conflicts of interest.

Abstract A 60-year-old Caucasian male was diagnosed with lung adenocarcinoma and multiple metastases to the bone, spleen, and brain. He underwent radiotherapy for the brain and lumbar spine metastases, plus chemotherapy (cisplatin and pemetrexed). The chemotherapy was discontinued due to vomiting and hyponatremia, and nivolumab was then administered. Eight months later, 18F-fluorodeoxyglucose positron emission tomography showed tracer uptake in the colon. Colonoscopy revealed a reddish multinodular polyp in the sigmoid colon. The polyp showed irregular microvessels. No colonic mucosal surface structures were obser...

CONCLUSION: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for isolated low-volume colorectal peritoneal metastases are not safe and effective, with low morbidity. It offers selected patients a highly favorable overall and relapse-free survival. See Video Abstract at http://links.lww.com/DCR/B2.

We describe two patients with advanced non ‐small‐cell lung cancer (NSCLC), including one in whom the definitive diagnosis of pulmonary pleomorphic carcinoma (PPC) was made by histopathology of the resected tumour and another in whom the diagnosis of “favor adenocarcinoma containing sarcomatoid components” was made by tissue biopsy. Both were resistant to first line platinum‐based chemotherapy, but responded dramatically to second line nivolumab therapy. We present two cases of pulmonary pleomorphic carcinoma (PPC) treated with Nivolumab. A 57 ‐year‐old man presented with a 3.5‐cm mass in the left l...

Many studies ascribe the risk of the appearance of this cancer to the Western life style : a sedentary life, obesity, and low -fiber, high -fat diets can promote the onset of disease.

We present a patient who received nivolumab for heterogeneity of right-sided metastatic colon carcinoma. Intervention: The patient was treated with nivolumab combined with chemotherapy. Outcome: The computed tomography showed mass lesion in the left lobe of liver remained stable while metastasis tumors under envelop of liver were exacerbated after 6 cycles of nivolumab combined with chemotherapy, and later regressed. Lessons: The status of mismatch repair in primary tumor and metastatic liver carcinoma is contradictory but using nivolumab demonstrated encouraging efficacy. This is the first case of pseudo progress...
