Chemotherapy agents are widely and effectively used for the treatment of different malignant tumors. Nonetheless, their use may lead to different adverse outcomes such as nephrotoxicity which is the main cause of morbidity and hospitalization of patients in intensive care units. Melatonin is a small molecule with pleiotropic healing properties and effectiveness in the management of a wide range of diseases. The aim of this study was to investigate the potential role of melatonin in the prevention of chemotherapy-induced nephrotoxicity at the preclinical level...

Vincristine is included in vincristine, cyclophosphamide, doxorubicin and prednisone (CHOP) chemotherapy protocols, which are the gold-standard treatment for high-grade canine lymphoma. Vincristine can result in relatively high rates of gastrointestinal toxicity, whereas vinblastine is generally well tolerated and thus may represent an under-utilized and minimally toxic alternative to vincristine. Our objective was to determine the response rate and toxicity associated with a single dose of vinblastine administered to dogs with treatment-naïve, intermediate to large-cell, multicentric lymphoma...

BACKGROUND: Cochlea sparing can reduce late ototoxicity in head and neck cancer patients treated with cisplatin-based radiochemotherapy. In this situation, a mean cochlear dose (MCD) constraint of 10 Gy has been suggested by others based on the dose-effect relationship of clinical data. We aimed to investigate whether this is feasible for primary and postoperative radiochemotherapy in locoregionally advanced tumors without compromising target coverage. PATIENTS AND METHODS: Ten patients treated with definitive and ten patients treated with adjuvant intensity-modulated radiotherapy (IMRT) and concurrent chemotherapy were investigated...

BACKGROUND: Differentiated thyroid cancer typically has an indolent clinical course but can cause significant morbidity by local progression. Surgery can be difficult due to the proximity to critical normal structures in the neck. Our objective was to review the safety, feasibility, and outcomes of definitive-intent intensity modulated radiation therapy (IMRT) and to analyze whether patients receiving concurrent chemotherapy (CC-IMRT) had higher rates of disease control and survival over IMRT alone in patients with unresectable or gross residual disease (GRD)...

BACKGROUND: In the era of intensity-modulated radiotherapy (IMRT), the role of additional concurrent chemotherapy (CC) to radiotherapy (RT) after induction chemotherapy (IC) compared to IC followed by RT alone remains unclear for stage II-IVB nasopharyngeal carcinoma (NPC) patients. The aim of this study was to evaluate the efficacy and toxicities of IC/RT and IC/CCRT in the treatment of NPC with volumetric modulated arc therapy (VMAT). METHODS: From January 2012 to March 2016, a total of 217 NPC patients were retrospectively assessed...

Background: Hypopharyngeal squamous cell carcinoma (HPSCC) is an aggressive head and neck squamous cell carcinoma with poor prognosis. Neoadjuvant chemotherapy (NACT) followed by concurrent chemoradiotherapy could provide better efficacy in HPSCC treatment. Identification of predictive biomarkers is critically needed to improve selection of patients who derive the most benefit from NACT. The aim of this study was to investigate whether transcobalamin I (TCN1) could be a novel predictive biomarker for NACT in HPSCC...

BACKGROUND: Time to start adjuvant therapy has been shown to be an important determinant of survival following curative resection of colorectal cancer. Time to start systemic therapy following diagnosis of metastatic colorectal cancer (mCRC) needs to be additionally studied and assessed. METHODS: This is a pooled analysis of the raw data of the comparator arms of two randomized studies (NCT00272051; NCT00305188). Univariate and Multivariate analysis of predictors of overall and progression-free survival was conducted through Cox regression analysis...

Background: The HER3 receptor functions as a major cause of drug resistance in cancer treatment. It is believed that therapeutic targeting of HER3 is required to improve patient outcomes. It is not clear whether a novel strategy with two functional cooperative miRNAs would effectively inhibit erbB3 expression and potentiate the anti-proliferative/anti-survival effects of a HER2-targeted therapy (trastuzumab) and chemotherapy (paclitaxel) on HER2-overexpressing breast cancer cells. Results: Combination of miR-125a and miR-205, as compared to either miRNA alone, potently inhibited expression of HER3 in HER2-overexpressing breast cancer BT474 cells...

BACKGROUND: Pilocytic astrocytoma is a low-grade central nervous system tumor most commonly seen in children. Dissemination from a primary intracranial tumor along the neuroaxis has been described at both presentation and disease progression. However, the development of an intradural extramedullary pilocytic astrocytoma independent of a primary intraparenchymal tumor in an adult patient with no history of pilocytic astrocytoma has rarely been reported. CASE PRESENTATION: A 69-year-old woman presented with progressive myelopathic symptoms and thoracic radicular pain...

BACKGROUND:  Prognosis in limited disease small-cell lung cancer (SCLC) after concurrent chemoradiotherapy is poor. While some studies show better survival after multimodality treatment including surgery, other trials failed to prove a surgery-related survival benefit. Therefore, this study investigated survival in stage IA-IIIB SCLC following surgery combined with chemotherapy and/or thoracic radiotherapy. METHODS:  We retrospectively reviewed all stage IA-IIIB SCLC patients without supraclavicular lymph node involvement at a single institution between January 1999 and August 2016 after multimodality treatment with curative intent...
