Second malignancies in hydroxyurea and interferon-treated Philadelphia-negative myeloproliferative neoplasms.

Objective: In an era of controversy in regard to 'hydroxyurea-leukaemogenicity' and when interferon-alfa2 (IFN) is being revived in the treatment of Philadelphia-negative myeloproliferative neoplasms (MPNs), we aim in this single-centre observational study to describe the frequencies of second malignancies in a cohort of MPN patients treated with hydroxyurea (HU) or IFN monotherapy or the combination of these agents.

Patients And Methods: Records of a MPN cohort of 196 patients were reviewed, and a retrospective analysis was performed on 90 patients treated with HU, 38 patients treated with IFN and 68 patients treated with both IFN and HU. Logistic regression was used to compare frequencies in second malignancies.

Limited Evidence for Robot-assisted Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Purpose: To evaluate available evidence on robot-assisted surgery compared with open and laparoscopic surgery.

Method: The databases Medline, Embase, and Cochrane Library were systematically searched for randomized controlled trials comparing robot-assisted surgery with open and laparoscopic surgery regardless of surgical procedure. Meta-analyses were performed on each outcome with appropriate data material available.

A nationwide Danish cohort study challenging the categorisation into right-sided and left-sided colon cancer.

Objectives: The categorisation of colon cancer (CC) into right-sided (RCC) and left-sided (LCC) disease may not capture more subtle variances in aetiology and prognosis. In a nationwide study, we investigated differences in clinical characteristics and survival of RCC versus LCC and of the complete range of CC subsites.

Design: Prospective nationwide cohort study.

Possible better long-term survival in left versus right-sided colon cancer - a systematic review.

Introduction: Colon cancer is one of the most frequent types of cancer in Denmark and the western world. Recent studies indicate that there are differences between right- and left-sided colon cancer with regard to epidemiology, clinical manifestation, pathology and prognosis. The present systematic literature review focuses on this subject.
