REVIEW
Huiqin Guo, Kangla Tsung
Tumor reductive therapy is to reduce tumor burden through direct killing of tumor cells. So far, there is no report on the connection between antitumor immunity and tumor reductive therapies. In the last few years, a new category of cancer treatment, immunotherapy, emerged and they are categorized separately from classic cytotoxic treatments (chemo and radiation therapy). The most prominent examples include cellular therapies (LAK and CAR-T) and immune checkpoint inhibitors (anti-PD-1 and CTLA-4). Recent advances in clinical immunotherapy and our understanding of the mechanism behind them revealed that these therapies have a closer relationship with classic cancer treatments than we thought...

Despite the urgency for prevention and treatment of lung adenocarcinoma (LUAD), we still do not know drivers in pathogenesis of the disease. Earlier work revealed that mice with knockout of the G-protein coupled receptor Gprc5a develop late onset lung tumors including LUADs. Here, we sought to further probe the impact of Gprc5a expression on LUAD pathogenesis. We first surveyed GPRC5A expression in human tissues and found that GPRC5A was markedly elevated in human normal lung relative to other normal tissues and was consistently down-regulated in LUADs...

BACKGROUND: The primary objective of our study was to assess the association of primary tumor lymph node ratio (LNR) in stage IV colorectal adenocarcinomas (CRC) with overall survival (OS) and the extent of metastatic disease in the liver. METHODS: We analyzed data on 53 stage IV CRC patients who underwent surgical resection of the primary tumor. The median LNR of 0.25 was used to stratify patients into high LNR (H-LNR) and low LNR (L-LNR) groups. Statistical comparison was performed using chi square test and multiple regression models...

Over the past decade we have seen significant changes in the biological characterization and strategies for treatment of mantle cell lymphoma (MCL). MCL is heterogeneous a disease, and so are the people that have it; although guidelines are appropriate, therapeutic approaches must be individualized based on a variety of factors. In this review, we summarize data on the range of therapeutic options, from observation in patients with slowly progressive low-tumor-burden MCL, to bendamustine-based regimens in typical MCL, to high-dose cytarabine-based regimens in young, fit patients...

PURPOSE OF REVIEW: The prevalence of obesity has risen dramatically in the general population and among cancer survivors in the last three decades. In this review, we highlight the impact of obesity on carcinogenesis and survival with a focus on bladder cancer and renal cell carcinoma (RCC). RECENT FINDINGS: Obesity presents an established risk factor for an up to 1.8-fold relative risk of RCC. Data with regard to bladder cancer are less abundant but support this association as well...

A 77-year-old Japanese man presented to our hospital with a 1-month history of low back pain and was diagnosed as having stage IV EGFR mutation-positive lung adenocarcinoma. After treatment with EGFR tyrosine kinase inhibitor and cytotoxic chemotherapy, nivolumab was started as fourth-line therapy. Remarkable regression of the primary tumor was observed, suggesting high anti-tumor activity of nivolumab. We retrospectively investigated the change in circulating tumor DNA (ctDNA) variant allele fractions in serial plasma samples before and after the nivolumab therapy...

We previously demonstrated that alkyl gallates coupled to triphenylphosphine have a selective and efficient antiproliferative effect by inducing mitochondrial uncoupling in vitro due to the increased mitochondrial transmembrane potential of tumor cells. Therefore, in this work, the in vivo antitumor activities of alkyl gallate triphenylphosphonium derivatives (TPP(+)C8, TPP(+)C10 and TPP(+)C12) were evaluated in a syngeneic murine model of breast cancer. We found that TPP(+)C10 increased the cytosolic ADP/ATP ratio and significantly increased the AMP levels in a concentration-dependent manner in TA3/Ha murine mammary adenocarcinoma cells...

Cyclin-dependent kinase 9 (CDK9), a subunit of the positive transcription elongation factor b (P-TEFb) complex, regulates gene transcription elongation by phosphorylating the carboxy-terminal domain (CTD) of RNA polymerase II (RNAPII).  The deregulation of CDK9/P-TEFb has important implications for many cancer types.  BAY 1143572 is a novel and highly selective CDK9/P-TEFb inhibitor currently being investigated in phase I studies. We evaluated the therapeutic potential of BAY 1143572 in adult T-cell leukemia/lymphoma (ATL)...

Purpose: Targeting the B-cell receptor (BCR) pathway with inhibitors of BTK and PI3K-delta is highly effective for the treatment of chronic lymphocytic leukemia (CLL). However, deep remissions are uncommon and drug resistance with single-agent therapy can occur. In vitro studies support the effectiveness of combing PI3K-delta and BTK inhibitors. <p>Experimental design: As CLL proliferation and survival depends on the microenvironment, we used murine models to assess the efficacy of the BTK inhibitor acalabrutinib combined with the PI3K-delta inhibitor ACP-319 in vivo We compared single-agent with combination therapy in TCL1-192 cell-injected mice, a model of aggressive CLL...

The primary curative modality for localized rectal cancer is total mesorectal excision (TME). Local control rate of rectal cancer has been improved after neoadjuvant chemoradiotherapy and even pathological complete response (pCR) has been demonstrated in a significant minority. Patients who achieve pCR to neoadjuvant chemoradiotherapy have an excellent prognosis compared with those without pCR. If the patients with complete response to neoadjuvant chemoradiation can be demonstrated by clinical findings and medical imaging (cCR), a non-operative management (NOM) strategy may be pursued to preserve sphincter function and avoid complications induced by TME, which is a new tendency in the treatment of rectal cancer in recent years...

BACKGROUND: We aimed to find the clinical value of metastatic tumor burden evaluated with F18-FDG PET/CT in gastric cancer patients, considering the human epidermal growth factor receptor 2 (HER2) status. METHODS: We retrospectively reviewed 124 patients with locally advanced or metastatic gastric cancer at Yonsei Cancer Center between January 2006 and December 2014 who had undergone baseline FDG PET/CT before first-line chemotherapy. We measured the maximum standardized uptake value from the primary tumor (SUVmax) and whole-body (WB) PET/CT parameters, including WB SUVmax, WB SUVmean, WB metabolic tumor volume (WB MTV), and WB total lesion glycolysis (WB TLG), in all metabolically active metastatic lesions (SUV threshold ≥2...

BACKGROUND: Neuroendocrine tumors (NETs) can secrete hormonal peptides that lead to additional symptom burdens. However, it is largely unknown whether and to what extent the additional symptom burdens translate into higher costs of care. This study aimed to examine the cost pattern of elderly NET patients during the first year of diagnosis, taking into account of the carcinoid syndrome status. METHODS: We used Surveillance, Epidemiology, and End Results Medicare data to identify elderly NET patients diagnosed between January 2003 and December 2011...

Evidence points to many benefits of "early palliative care," the provision of specialist palliative care services upstream from the end of life, to improve patients' quality of life while living with a serious illness. Yet most trials of early palliative care have not included patients with hematologic malignancies. Unfortunately, patients with hematologic malignancies are also known to have substantial illness burden, poor quality of life, and aggressive care at the end of life, including a greater likelihood of dying in the hospital, receiving chemotherapy at the end of life, and low hospice utilization, compared to patients with solid tumors...

Despite potentially curative surgery pancreatic cancer has a dismal prognosis. Serum cancer antigen 19-9 (CA 19-9) correlates with tumor burden, resectability and survival in patients with pancreatic ductal adenocarcinoma. Identification of novel biomarkers may facilitate early diagnosis of pancreatic cancer and improve survival. Pancreatic juice is a rich source of cancer-specific proteins rendering it a promising tool for identifying biomarkers. Recent proteomic and microRNA expression analyses have identified several biomarkers of potential diagnostic and prognostic value...

Vasoactive intestinal peptide (VIP) is a neuroendocrine peptide hormone that has potent anti-inflammatory activities. VIP signaling through its receptor VPAC1 on T cells leads to reduced proliferation and a reduction in pro-inflammatory cytokine secretion. We report here that inhibition of the VIP pathway with a peptide antagonist significantly enhances a T-cell-dependent, autologous anti-leukemia response in murine models of acute myeloid leukemia and T lymphoblastic leukemia. Subcutaneous administration of the VIP antagonist, VIPhyb, resulted in reduced tumor burden and significantly enhanced survival (30-50% survival) over vehicle-treated controls (0-20% survival)...
