Laparoscopic surgery has been increasingly used in rectal cancer surgery. Though there are still some controversies, most of the research results support that the outcome is similar for rectal cancer patients with either laparoscopic or open surgery, in term of short-term such as safety and efficacy and long-term such as oncologic outcome. Standardization of laparoscopic training together with the comprehensive management concept are the prerequisites of laparoscopic rectal cancer surgery. Those doctors who do minimally invasive surgery should follow the rationale that smaller incision and sphincter preservation are secondary to safety and oncological result of the patients...

It has been established that signal transducer and activator of transcription 3 serves as an oncoprotein in various human cancers; targeting it is therefore a reasonable approach for emerging cancer therapies. Cryptotanshinone, a natural compound extracted from the root of Salvia miltiorrhiza Bunge, has been identified as a potential STAT3 inhibitor. However, its functional role in renal cell carcinomas remains largely unknown. Therefore, we investigated the mode of action for cryptotanshinone. We found that cryptotanshinone substantially suppressed cancer cell growth while it promoted cell apoptosis by inhibiting the phosphorylation of STAT3 at Tyr705 and its blocking nuclear translocation...

Ovarian cancer is the deadliest of all gynecologic cancers. Despite success with initial chemotherapy, the majority of patients relapse with an incurable disease. Development of chemotherapy resistance is a major factor for poor long-term survival in ovarian cancer. The biological effects of estrogens are mediated by estrogen receptor alpha (ERα) and estrogen receptor beta (ERβ). Emerging evidence suggests that ovarian cancer cells express ERβ that functions as a tumor suppressor; however, the clinical utility of ERβ agonists in ovarian cancer remains elusive...

Natural polyphenols are organic chemicals which contain phenol units in their structures. They show anticancer properties. However, a key problem is their short half-life and low bioavailability under in vivo conditions. Still, definitively demonstrating the human benefits of isolated polyphenolic compounds (alone or in combination) using modern scientific methodology has proved challenging. The main discrepancy between experimental and clinical observations is the frequent use of non-physiologically relevant concentrations of polyphenols in mechanistic studies...

Polymorphisms in drug-metabolizing enzymes might not completely explain inter-individual differences in toxicity profiles of patients with colorectal cancer (CRC) that receive folinic acid/5-fluorouracil/oxaliplatin (FOLFOX4). Recent data indicate that the immune system could contribute to FOLFOX4 outcomes. In light of the immune inhibitory nature of human leukocyte antigen-G (HLA-G), a non-classical major histocompatibility complex (MHC) class I molecule, we aimed to identify novel genomic markers of grades 3 and 4 (G3-4) toxicity related to FOLFOX4 therapy in patients with CRC...

Lung cancer causes huge mortality to population, and pharmaceutical companies require new drugs as an alternative either synthetic or natural targeting lung cancer. The conventional therapies cause side effects, and therefore, natural products are used as a therapeutic candidate in lung cancer. Chemical diversity among natural products highlights the impact of evolution and survival of fittest. One such neglected natural product is Ganoderma lucidum used for promoting health and longevity for a longer time...

Blood transfusion is a clinical replacement therapy with many successes with some benefit and, also, some harm. Cancer is a multifaceted disease potentially associated with the immune system's weakness where the cancerous tumor cells escape from the immune system. Allogeneic blood transfusion, through five major mechanisms including the lymphocyte-T set, myeloid-derived suppressor cells (MDSCs), tumor-associated macrophages (TAMs), natural killer cells (NKCs), and dendritic cells (DCs) can help the recipient's defense mechanisms...

BACKGROUND: Adult hemophagocytic lymphohistiocytosis is a secondary immunopathologic phenomenon, mainly secondary to malignancy, infection, or autoimmune disorders. The performance of diagnostic criteria, studied in the pediatric population, is yet to be validated in the adult population. Some of the criteria include cytopenias and organomegaly that are inherent features to malignant processes, thus making the diagnosis of hemophagocytic lymphohistiocytosis a challenge in patients with cancer...

Euphorbia species have been used in traditional medicine in many countries for the treatment of cancer. This paper aims to evaluate the capability of a new lathyrane diterpene isolated from Euphorbia aellenii to induce apoptosis in the Caov-4 cell line to determine the underlying mechanism of its anticancer effects. A new 6(17)-epoxylathyrane diterpenes: aellinane from Euphorbia aellenii was evaluated for viability of Caov-4 cells by MTT method. Apoptosis induction by lathyrane diterpene was confirmed by annexin V-FITC/PI staining, and caspase-6 activation...

OBJECTIVE: Limitations associated with current animal models serve as a major obstacle to reliable preclinical evaluation of therapies in pancreatic cancer (PC). In an effort to develop more reliable preclinical models, we have recently established a subcutaneous patient-derived xenograft (PDX) model. However, critical aspects of PC responsible for its highly lethal nature, such as the development of distant metastasis and cancer cachexia, remain underrepresented in the flank PDX model...

Oral cancer is among the most prevalent cancers in the world. Moreover, it is one of the major health problems and causes of death in many regions of the world. The traditional treatment modalities include surgical removal, radiation therapy, systemic chemotherapy, or a combination of these methods. In recent decades, there has been significant interest in intraoral site-specific chemoprevention via local drug delivery using polymeric systems. Because of its easy accessibility and clear visibility, the oral mucosa is amenable for local drug delivery...

Angiogenesis leads to the growth, progression, and metastases of a variety of solid tumors, including metastatic colorectal cancer (mCRC), involving particularly the family of vascular endothelial growth factors (VEGF) and their receptors (VEGFR). Several anti-angiogenic inhibitors are already registered for mCRC therapy: bevacizumab, aflibercept, ramucirumab, regorafenib. Nintedanib is a new triple angiokinase oral inhibitor that potently blocks the proangiogenic pathways mediated by VEGFR, platelet-derived growth factor receptor (PDGFR), and fibroblast growth factor receptor (FGFR)...

Despite advances in treatments like chemotherapy and radiotherapy, metastatic cancer remains a leading cause of death for cancer patients. While many chemotherapeutic agents can efficiently eliminate cancer cells, long-term protection against cancer is not achieved and many patients experience cancer recurrence. Mobilizing and stimulating the immune system against tumor cells is one of the most effective ways to protect against cancers that recur and/or metastasize. Activated tumor specific cytotoxic T lymphocytes (CTLs) can seek out and destroy metastatic tumor cells and reduce tumor lesions...

The importance of the P450 enzyme CYP1B1 in both cancer therapy and prevention are reviewed and evidence is discussed, which provides strong biological plausibility for the therapeutic merits of this approach. The significant resistance to chemotherapy among common cancers, and the realization that in many cases chemotherapy leaves behind drug-resistant cancer cells that eventually cause recurrence and metastatic disease, has recently prompted the search for natural compounds that would circumvent this problem...

Epigenetic changes resulting from aberrant methylation patterns are a recurrent observation in hematologic malignancies. Hypomethylating agents have a well-established role in the management of patients with high-risk myelodysplastic syndrome or acute myeloid leukemia. In addition to the direct effects of hypomethylating agents on cancer cells, there are several lines of evidence indicating a role for immune-mediated anti-tumor benefits from hypomethylating therapy. Areas Covered: We reviewed the clinical and basic science literature for the effects of hypomethylating agents, including the most commonly utilized therapeutics azacitidine and decitabine, on immune cell subsets...

Protein nanocarriers possess unique merits including minimal cytotoxicity, numerous renewable sources, and high drug-binding capability. In opposition to delivery carriers utilizing hydrophilic animal proteins, hydrophobic plant proteins (e.g, zein) have great tendency in fabricating controlled-release particulate carriers without additional chemical modification to stiffen them, which in turn evades the use of toxic chemical crosslinkers. Moreover, zein is related to a class of alcohol-soluble prolamins and generally recognized as safe (GRAS) carrier for drug delivery...

The ATP-binding cassette (ABC) drug transporter ABCG2 can actively efflux a wide variety of chemotherapeutic agents out of cancer cells and subsequently reduce the intracellular accumulation of these drugs. Therefore, the overexpression of ABCG2 often contributes to the development of multidrug resistance (MDR) in cancer cells, which is one of the major obstacles to successful cancer chemotherapy. Moreover, ABCG2 is highly expressed in various tissues including the intestine and blood-brain barrier (BBB), limiting the absorption and bioavailability of many therapeutic agents...

REVIEW
Sin-Aye Park, Young-Joon Surh
The tumor microenvironment provides a niche in which cancer cells and their surrounding stromal cells reside and in which their interactions occur. The cross talk between cancer and stromal cells in the tumor microenvironment promotes many biological processes to support cancer cell growth, invasion, angiogenesis, and metastasis. Recently, not only cancer cells but also multiple types of surrounding stromal cells, including endothelial cells, immune cells, and fibroblasts in the tumor microenvironment, have been recognized to be attractive targets for reducing resistance to anticancer therapy and tumor recurrence...

Recent breakthroughs in next-generation sequencing technology and complementary genomic platforms have transformed our capacity to interrogate the molecular landscapes of human cancers, including childhood brain tumors. Numerous high-throughput genomic studies have been reported for the major histologic brain tumor entities diagnosed in children, including interrogations at the level of the genome, epigenome, and transcriptome, many of which have yielded essential new insights into disease biology. The nature of these discoveries has been largely platform dependent, exemplifying the usefulness of applying different genomic and computational strategies, or integrative approaches, to address specific biologic and/or clinical questions...
