Specific metabolic biomarkers as risk and prognostic factors in colorectal cancer.

Advances in genomics, molecular pathology and metabolism have generated many candidate biomarkers of colorectal cancer with potential clinical value. Epidemiological and biological studies suggest a role for adiposity, dyslipidaemia, hyperinsulinemia, altered glucose homeostasis, and elevated expression of insulin-like growth factor (IGF) axis members in the risk and prognosis of cancer. This review discusses some recent past and current approaches being taken by researches in obesity and metabolic disorders.

VDR gene single nucleotide polymorphisms and their association with risk of oral cavity carcinoma.

Vitamin D3 (1,25(OH)2D3 (1,25-dihydroxyvitamin D3)) is a hormone playing a crucial role in numerous biological processes in the human body, including induction and control of cell proliferation and differentiation. Numerous data relate the vitamin D3 level with various types of cancer. It has been suggested that SNPs in the vitamin D3 receptor (VDR) gene might influence both the risk of cancer occurrence and cancer progression.

Maxillary reconstruction using a multi-element free fibula flap based on a three-dimensional polyacrylic resin model.

Preoperative preparation of working models of the skull and free bone flaps using the digital print technology and photocured polyacrylic resins may be of a great benefit to the patient, for whom a virtual resection and reconstruction procedure may be planned in detail and performed. The purpose of mid-facial reconstruction using 3D models is to plan a functional mid-facial reconstruction procedure in order to restore supportive function of intraorbital structures and to make placement of dental implants and further prosthetic rehabilitation possible.Maxillary and mid-facial reconstruction using a free fibula flap based on a three-dimensional working model was performed in a patient diagnosed with a squamous cell carcinoma of the left maxillary sinus penetrating to the orbit, the ethmoid complex, and the pterygopalatine fossa.

Salvage surgery of recurrence after laryngectomy--when should the alt free flap be modified?

Background: Reconstruction of the pharynx and cervical esophagus has significantly progressed in the last 2 decades. A revolution in microvascular surgery has provided numerous choices for primary restoration, or in secondary reconstructions necessary for recurrences or complications of primary surgery. The goals of reconstruction after laryngopharyngoesophagectomy are to provide continuity of the alimentary tract, to protect major blood vessels, to heal the primary wound, and to restore the swallowing and breathing functions with minimal donor site and neck morbidity and deformation.

The use of prefabrication technique in microvascular reconstructive surgery.
