BACKGROUND AND OBJECTIVES: We conducted a dose-finding study for 5-fluorouracil (5-FU) administered with cisplatin (CDDP) and mitomycin C (MMC) to find an improved regimen for hyperthermic intraperitoneal chemotherapy (HIPEC) for advanced gastric cancer (GC). METHODS: The appropriate HIPEC regimen previously determined in vitro was 5-FU (200 µg/mL), MMC (2 µg/mL), and CDDP (10 µg/mL) at hyperthermic conditions (42°C) for 30 min. This was a clinical study to determine the recommended dose of 5-FU in combination with MMC and CDDP at 42°C for 30 min and to evaluate HIPEC safety in patients at high risk of developing peritoneal metastases following GC surgery...

OBJECTIVES: To investigate the relevance of lymphangiogenic gene expression in primary and liver metastasis of colorectal cancer (CRC) and identify determinants of lymphatic invasion. BACKGROUND: Lymphatic development promoting vascular endothelial growth factor C (VEGFC) is associated with poor outcome in primary CRC. For colorectal liver metastasis (CRLM), intrahepatic lymph invasion and lymph node metastasis are poor prognostic factors. Exact biological factors promoting lymphatic involvement remain elusive, just as the association with molecular subtypes of CRC...

Multidrug resistance (MDR) and metastasis are the major obstacles in cancer chemotherapy. Nanotechnology-based combination therapy is a useful strategy. Recently, the combination of biologics and small drugs has attracted much attention in cancer therapy. Yet, the treatment outcomes are often compromised by the different pharmacokinetics profiles of the co-administered drugs, thus leading to inconsistent drug uptake and suboptimal drug combination at the tumor sites. Nanotechnology-based codelivery offers a promising method to address this problem, which is well demonstrated in the use of small drugs combination...

REVIEW
Luana Schito, Gregg L Semenza
Intratumoral hypoxia (reduced O2 availability) is a common finding in human cancer and leads to increased activity of hypoxia-inducible factors (HIFs), which regulate the expression of genes that contribute to angiogenesis, metabolic reprogramming, extracellular matrix remodeling, epithelial-mesenchymal transition, motility, invasion, metastasis, cancer stem cell maintenance, immune evasion, and resistance to chemotherapy and radiation therapy. Conventional anticancer therapies target well-oxygenated and proliferating cancer cells, whereas there are no approved therapies that target hypoxic cancer cells, despite growing clinical and experimental evidence indicating that intratumoral hypoxia is a critical microenvironmental factor driving cancer progression...

To survive inhospitable environments, tumor cells are forced to remodel their signaling pathways by altering transcription, translation, and post-translational modifications. This adaptation is regulated in a spatial and temporal manner and gives rise to individual tumor cells with distinct gene expression and metabolic signatures. Such phenotypic heterogeneity is the result of tumor cell plasticity, which-together with the genetic background of the tumor-determines whether cells resist environmental stress, enter dormancy, or metastasize...

REVIEW
Daniele V F Tauriello, Eduard Batlle
Colorectal cancer (CRC) diagnosis often occurs at late stages when tumor cells have already disseminated. Current therapies are poorly effective for metastatic disease, the main cause of death in CRC. Despite mounting evidence implicating the tumor microenvironment in CRC progression and metastasis, clinical practice remains predominantly focused on targeting the epithelial compartment. Because CRCs remain largely refractory to current therapies, we must devise alternative strategies. Transforming growth factor (TGF)-β has emerged as a key architect of the microenvironment in poor-prognosis cancers...

IL-6 has been found to be associated with poor response to chemoradiotherapy and poor overall prognosis of patients with cervical cancer. However, little is known about the clinicopathological significance of IL-6 receptor (IL-6R) expression in the setting of cervical cancer. To investigate the clinicopathological meaning of IL-6R in cervical cancer, expression of IL-6R was detected using immunohistochemistry in cervical cancer tissue microarray composed of 98 cases of cervical cancer and paired normal controls...

Metastasis to the posterior thoracic paraaortic lymph nodes rarely occurs in esophageal cancer, and a treatment strategy has not been established. We treated two cases of esophageal cancer with this type of metastasis; in both cases, we successfully performed surgical resection after neoadjuvant chemotherapy. In case 1, the patient received neoadjuvant chemotherapy, which consisted of docetaxel, cisplatin and 5-fluorouracil, and then underwent dissection of the posterior thoracic paraaortic lymph nodes. The left thoracic approach was used together with subtotal esophagectomy via a right thoracotomy...

Tumour metastasis in the lymphatics is a crucial step in the progression of breast cancer. The dynamics by which breast cancer cells (BCCs) travel in the lymphatics remains poorly understood. The goal of this work is to develop a model capable of predicting the shear stresses metastasising BCCs experience using numerical and experimental techniques. This paper models the fluidic transport of large particles ([Formula: see text] where [Formula: see text] is the particle diameter and W is the channel width) subjected to lymphatic flow conditions ([Formula: see text]), in a [Formula: see text] microchannel...

Epidermal cysts are cystic tumors lined with keratinized squamous layer and filled with keratin debris. Epidermal cysts may develop by implantation of surface epidermal layer into the dermis or subcutaneous tissue after trauma or surgical procedures. Cervix cancer spreads either directly or via the vascular and lymphatic systems. Distant skin metastasis of endometrium or cervix cancer is very rare. In this case report, a patient who had a history of cervix cancer operation 11 years ago and presented with a mass that mimicked incision line metastasis and was histopathologically diagnosed with epidermal cyst is presented...
