Objectives: To obtain health-related quality of life valuations (ie, utilities) for human papillomavirus (HPV)-related cancer health states of vulval, vaginal, penile, anal and oropharyngeal cancers for use in modelling cost-effectiveness of prophylactic HPV vaccination. Methods: Written case descriptions of each HPV-associated cancer describing the 'average' patient surviving after the initial cancer diagnosis and treatment were developed in consultation with oncology clinicians. A general overview, standard gamble questionnaire for each health state and a quiz was conducted in 120 participants recruited from the general population. Results: In the included population sample (n= 99), the average age was 43 years (range = 18-70 years) with 54% men, 44% never married/43% married, 76% education beyond year 12 and 39% employed full-time. The utility values for the five health states were 0.57 (95% CI 0.52 to 0.62) for anal cancer, 0.58 (0.53 to 0.63) for oropharyngeal cancer, 0.59 (0.54 to 0.64) for vaginal cancer, 0.65 (0.60 to 0.70) for vulval cancer and 0.79 (0.74 to 0.84) for penile cancer. Participants demonstrated a very good understanding of the symptoms, diagnosis and treatment of these cancers with a mean score of 9 (SD=1.1) on a 10-item quiz. Conclusions: This study provides utility estimates for the specific HPV-related cancers of vulval, vaginal, penile, anal and oropharyngeal cancers valued by a general population sample using standard gamble. The results demonstrate considerable quality of life impact associated with surviving these cancers that will be important to incorporate into modelling cost-effectiveness of prophylactic HPV vaccination in different populations.

Objective: To determine whether medical students perceive a foundation and core trainee finals revision programme as useful. Design: Questionnaires were used to assess students' perception of the teaching programme. Setting: A medical school in the South of England. Participants: There were 106 final year medical students in the cohort. Results: The teaching scored well in all facets analysed and scored best on enthusiasm, interactivity and communication. Conclusions: We provide a framework for how foundation and core trainees could provide a very well received teaching programme benefiting medical students, the doctors and the medical school.

Short-course preoperative radiotherapy (SC-RT) followed by total mesorectal excision (TME) is one therapeutic option for locally advanced rectal cancer (LARC) patients. Since radio-induced DNA damage may affect tumor immunogenicity, Myeloid-derived suppressor cells (MDSCs) and T regulatory cells (Tregs) were evaluated in 13 patients undergoing SC-RT and TME for LARC. Peripheral Granulocytic-MDSCs (G-MDSC) [LIN-/HLA-DR-/CD11b+/CD14-/CD15+/CD33+], Monocytic (M-MDSC) [CD14+/HLA-DR-/lowCD11b+/CD33+] and Tregs [CD4+/CD25hi+/FOXP3+- CTLA-4/PD1] basal value was significantly higher in LARC patients compared to healthy donors (HD). Peripheral MDSC and Tregs were evaluated at time 0 (T0), after 2 and 5 weeks (T2-T5) from radiotherapy; before surgery (T8) and 6-12 months after surgery (T9, T10). G-MDSC decreased at T5 and further at T8 while M-MDSC cells decreased at T5; Tregs reached the lowest value at T5. LARC poor responder patients displayed a major decrease in M-MDSC after SC-RT and an increase of Treg-PD-1. In this pilot study MDSCs and Tregs decrease during the SC-RT treatment could represent a biomarker of response in LARC patients. Further studies are needed to confirm that the deepest M-MDSC reduction and increase in Treg-PD1 cells within 5-8 weeks from the beginning of treatment could discriminate LARC patients poor responding to SC-RT.

Background The incidence of metachronous cancer will become an important clinical consideration as the life expectancy of the population increases and as rates of curative resection improve. Objective To assess the pattern of metachronous cancer development following curative resection of colorectal cancer in an unselected patient population offered postoperative colonoscopic surveillance. Method Prospective clinical follow-up after curative colorectal cancer resection and surveillance colonoscopy with or without polypectomy in accordance with the national guidelines. Actuarial analysis and competing risk analysis were performed to account for death and recurrence and to stratify for age, gender, stage, and tumor site. Results Five hundred thirty-eight patients with median follow-up 4 years 2 month (0-16) years. Fifteen patients (3%) developed metachronous cancer, at a median time interval of 90 months from primary resection. Thirteen metachronous cancer patients (87%, 13/15) underwent one to five surveillance colonoscopies: nine patients were asymptomatic at time of diagnosis of metachronous cancer. Competing risks analysis suggests that the adjusted cumulative incidence in males aged 55 is 4% at 10 years compared with 1% in females aged 85 years old. Conclusions A patient aged under 65 at the time of the primary curative resection carries a 2% 5-year risk of metachronous cancer, implying that 3 year surveillance colonoscopy is justified. Whereas patients aged over 75 carry less than a 2% 10-year risk, implying that it is seldom warranted to repeat the colonoscopy more frequently than every 5 years. A stratified approach to the frequency of surveillance colonoscopy requires further consideration. © 2013 Wiley Periodicals, Inc.

Purpose: The aim of this study was to determine if mechanical bowel preparation (MBP) influences the intramucosal bacterial colony count in the colon. Materials and methods: Macroscopically normal colon mucosa was collected from 37 patients (20 with and 17 without MBP) who were undergoing elective colorectal surgery at three hospitals. The biopsies were processed and cultured in the same laboratory. Colony counts of the common pathogens Escherichia coli and Bacteroides: as well as of total bacteria were conducted. The study groups were comparable with regard to age, gender, antibiotics use, diagnosis and type of resection. Results: MBP did not influence the median colony count of E. coli, Bacteroides or total bacteria in our study. Conclusions: MBP did not affect the intramucosal bacterial count in this study. Further studies are suggested to confirm these findings. © Springer-Verlag 2009.
