INTRODUCTION: We aimed to analyze the clinical and histological effects of chemotherapy in superficial esophageal squamous cell carcinoma (SESCC). METHODS: We analyzed tumor samples from five patients with cT1bN1M0 who underwent subtotal esophagectomy following two courses of a new triplet chemotherapy regimen including docetaxel, cisplatin, and 5-fluorouracil (DCF). To assess the histological effects of chemotherapy, resected specimens were analyzed by macroscopic examination, hematoxylin & eosin (HE) staining, immunohistochemical (IHC) staining (p53, Ki-67 and cytokeratin) and periodic acid-Schiff (PAS) staining...

PURPOSE: Irinotecan (CPT-11) in combination with 5-fluorouracil (5FU) is widely used in the treatment of colorectal cancer. We assessed potential clinical variables that may predict toxicity and more specifically the role of UGT1A1 polymorphisms associated with irinotecan toxicity. We used data from the PETACC3 trial, which randomised patients in adjuvant setting to 6 months of leucovorin (LV) and 5FU (LV5/FU2) or LV5/FU2 + irinotecan. PATIENTS AND METHODS: Clinical and toxicity data were available for 2982 patients, DNA was available for 1200 (40%) of these patients...

Uridine triacetate has been shown to be an effective antidote against mortality and toxicity caused by either overdoses or exaggerated susceptibility to the widely used anticancer agents 5-fluorouracil (5-FU) and capecitabine. However, a direct assessment of efficacy based on when emergency treatment was initiated was not clinically feasible. In this study we used mouse models of 5-FU overdose and of dihydropyrimidine dehydrogenase (DPD) deficiency to compare the efficacy of uridine triacetate in reducing toxicity and mortality when treatment was initiated at time points from 4 to 144 h after administration of 5-FU...

Store-and-forward teledermatology involves transmission of a patient's images to a healthcare provider and subsequent response from the provider about the diagnosis or management. Furthermore, teledermatology in which mobile phones (e.g. smartphones) are utilized for communication between the patient and their provider is referred to as mobile-teledermatology. In this study, we investigate the use of mobile-teledermatology in the management of actinic keratoses. We demonstrate that mobile-teledermatology may enhance communication between the patient and their provider when managing cutaneous disease and that even individuals in older age groups are highly satisfied with this type of follow up...

5-fluorouracil, a fluoropyrimidine antineoplastic drug, is used to topically treat actinic keratoses. Local skin reactions to the medication are common and anticipated. However, severe adverse events from topical 5-fluorouracil are rare and unexpected. A 69-year-old man with a lower lip actinic keratosis developed severe neutropenia on day 11 of topical 5-fluorouracil treatment - after 14 applications. After receiving a subcutaneous injection of filgrastim, his neutrophil count normalized. The PubMed database was used to search the following terms: agranulocytosis, cream, 5-fluorouracil, granulocytopenia, neutropenia, severe, systemic, topical, and toxicity...

Cutaneous squamous cell carcinoma (SCC) is among the most common cancers in humans, and many patients with SCC will develop multiple tumors within their lifetime. The field cancerization concept, originally proposed over 60 years ago, hypothesized that multiple primary cancers may arise simultaneously and coexist with subclinical precursor lesions within a defined field. Genetic sequencing of SCC and precursor lesions has identified what may be the earliest clonal proliferations in SCC development and confirmed that field cancerization in the skin is mediated by ultraviolet radiation...

To date, there is no consensus regarding first‑line chemotherapy for patients with HER2‑negative, locally advanced/metastatic gastric cancer (a/m GC). In the present study we reported a retrospective case‑series of patients treated with a weekly regimen containing timed‑flat infusion of 5‑fluorouracil (TFI/5‑FU), docetaxel and oxaliplatin. From June 2007 to July 2017, 32 consecutive a/m GC patients were treated with first‑line standard (st) or modulated (mod) 'FD/FOx' regimen: Weekly 12 h (from 10...

Nuclear Nrf2 (nNrf2) binding to the antioxidant response element may promote chemoresistance in colorectal cancer. However, the shuttling of Nrf2 between cytoplasm and nucleus in colon cancer cells has revealed the possibility that cytoplasmic location of Nrf2 (cNrf2) may play a specific role in chemoresistance. Transfection of a nuclear location sequence (NLS)-wild-type or NLS-mutated Nrf2 expression vector into a stable shNrf2 HCT116 clone using the MTT assay to examine whether chemoresistance induced by cNrf2 may be greater than nNrf2...

New anticancer agents with lower toxicity have been always urged because of drug resistance associated with overused chemotherapy agents. In this study, steviol, a colonic metabolite of natural sweetener and also a component in leaves of stevia rebaudiana bertoni , was found to possess intensive anticancer activity on the human gastrointestinal cancer cells. Steviol inhibited six human gastrointestinal cancer cells intensively as 5-fluorouracil did at 100 μg/mL. The inhibition mechanism follows mitochondrial apoptotic pathway that was evidenced by increase of Bax/Bcl-2 ratio, activation of p21 and p53; and caspase 3-independent mechanism was also involved...

Chemotherapeutic 5-fluorouracil (5-FU) combined with oxaliplatin is often used as the standard treatment for colorectal cancer (CRC). The disturbing side effects and drug resistance commonly observed in chemotherapy motivate us to develop alternative optimal therapeutic options for CRC treatment. Chrysin, a natural and biologically active flavonoid abundant in propolis, is reported to have antitumor effects on a few CRCs. However, whether and how chrysin achieves similar effectiveness to the 5-FU combination is not clear...

Metastatic pancreatic ductal adenocarcinoma (mPDAC) is a lethal disease with a poor 5-year survival. Systemic treatments can be used to control symptoms and prolong life. Cytotoxic chemotherapies are commonly administered, with combination treatments, such as fluorouracil, folinic acid, irinotecan and oxaliplatin (FOLFIRINOX) or nab-paclitaxel and gemcitabine showing the largest clinical benefits. Newer genomic classifications of PDAC may provide a rationale for targeted therapies or immunotherapies, although at present these remain largely experimental...

Renal cell carcinoma (RCC) is highly resistant to chemotherapies. The lack of efficacious treatment for metastatic RCC has led to a poor 5-year survival rate. Here, we found that Apoptosis-stimulating protein of p53-2(ASPP2) was frequently decreased in primary RCC tissues in comparison with non-tumoural kidney controls. Decreased ASPP2 was correlated with high grades and poor outcomes of RCC. Further studies revealed that ASPP2 downregulation promoted EMT and increased resistance to 5-Fluorouracil (5-FU)-induced apoptosis...

BACKGROUND: Continuous-infusion 5-fluorouracil (5FU) and calcium leucovorin plus nab-paclitaxel and oxaliplatin have been shown to be active in patients with pancreatic cancer. As a protracted low-dose infusion, 5FU is antiangiogenic, and has synergy with bevacizumab. As shown in the treatment of breast cancer, bevacizumab and nab-paclitaxel are also synergetic. OBJECTIVE: In this paper we retrospectively analyze the survival of 65 patients with advanced pancreatic cancer who were treated with low-dose continuous (metronomic) chemotherapy given in conjunction with conventional anti-VEGF therapy...
