Clinical decision-making in a multidisciplinary gynaecological cancer team: a qualitative study

Objective  To explore the factors that influence treatment decision-making in a gynaecological cancer team (MDT).
Design  Qualitative study using interviews and observations.
Setting  Gynaecological cancer MDT meetings and participants' offices.
Sample  A gynaecological cancer MDT and members of that team.
Methods  Observations of ten MDT meetings and semistructured interviews with 16 team members. Data analysis using the constant comparison technique of grounded theory and ethnography.
Main outcome measures  Factors affecting treatment decisions in the MDT meetings.
Results  Disease-centred information was central to decision-making, whereas patient-centred factors such as patient choice and co-morbidity were more peripheral. This was partly due to variation in team members' type and level of participation: senior clinicians occupied the most dominant roles in discussions and decision-making, whereas nurses contributed less but were more likely to focus on patient-related factors. Three main decision-making pathways emerged: a short discussion followed by a clear decision, a prolonged discussion ending in a definite treatment plan, and a lengthy discussion with no clearly stated decision at the end. The type of pathway followed depended on a case's complexity and the extent of agreement among team members.
Conclusions  The process of treatment decision-making was not consistent for all women but was affected by factors such as the complexity of the case, which team members participated, and the extent of team members' agreement. Improvements are needed to ensure patient-centred information is included for all women and that clear decisions are reached and recorded in all cases.     

Official Positions of the International Society for Clinical Densitometry and executive summary of the 2007 ISCD Position Development Conference.

The International Society for Clinical Densitometry (ISCD) convenes a Position Development Conference (PDC) every 2 yr to make recommendations for standards in the field of bone densitometry. The recommendations are based on clinically relevant issues in bone densitometry such as quality control, acquisition, analysis, interpretation and reporting. Topics for consideration are developed by the ISCD Board of Directors and its Scientific Advisory Committee. Clinically relevant questions related to each topic area are assigned to task forces for a comprehensive review of the medical literature and subsequent presentation of the reports to an international panel of experts. For this PDC, the Expert Panel included representatives of the American Society for Bone and Mineral Research, International Bone and Mineral Society and the National Osteoporosis Foundation. The recommendations of the PDC Expert Panel are then reviewed by the ISCD Board of Directors. Recommendations that are approved become Official Positions of the ISCD. The most recent PDC was held July 20-22, 2007, in Lansdowne, Virginia, USA. Topics considered included vertebral fracture assessment, technical and clinical issues relevant to dual-energy X-ray absorptiometry (DXA), and bone densitometry technologies other than central DXA. This report describes the methodology and the results of the Lansdowne, Virginia, USA 2007 PDC, and a summary of all ISCD Official Positions, including the ones recently adopted by this PDC and the 2007 Pediatric PDC held in Montreal, Quebec, Canada.

Malignant evolution of choroid plexus papilloma

Choroid plexus tumors are rare CNS neoplasms. The distinction between choroid plexus papilloma (CPP) and choroid plexus carcinoma (CPC) is made on the basis of clinical and histological criteria. Malignant evolution of CPP may occur, and the presence of mitotic figures in CPP may predict the likelihood of recurrence or malignant evolution. Close surveillance is mandated for these patients. We report on two such cases of CPP that transformed to CPC at the time of recurrence.     

Neonatal necrotizing enterocolitis: a retrospective and multicentric review of 331 cases

The authors retrospectively review 331 cases of necrotizing enterocolitis from 13 different departments of pediatric surgery; 184 cases were treated only medically at the acute stage (47 of whom developed intestinal stricture) and 147 cases were operated on at the acute stage. The different procedures of acute surgical intervention are reported and the results of two surgical procedures are compared. The first is a classical one comprising a laparotomy with exploration of the intestinal tract and resection of the necrotic segments followed by enterostomy above the resected area. The other procedure comprises a minimal laparotomy in the right lower quadrant with ileostomy above necrotic areas, without resection of necrotic segments associated with peritoneal drainage. The results are assessed using the postoperative mortality rate and the number of secondary intestinal strictures. Mortality during the first postoperative month occurred in 27.9% of cases, and intestinal strictures were noted in 31.3% of cases after acute surgical procedure.     

No association between HPV infection and the neoplastic progression of esophageal squamous cell carcinoma: result from a cross-sectional study in a high-risk region of China

Esophageal cancer is a leading cause of cancer death, especially in developing countries. In high-risk regions, squamous cell carcinoma is the most common type of esophageal cancer, and its etiology remains poorly understood. The purpose of this study was to evaluate the association between human papillomavirus (HPV) infection and esophageal squamous cell carcinoma (ESCC) and related precursor lesions in a high-risk area of China. We conducted a cross-sectional study among adult inhabitants of Linxian, China. All subjects were interviewed about potential risk factors, had the length of their esophagus sampled by a balloon cytology examination and underwent endoscopy with mucosal iodine staining and biopsy of all unstained lesions. A multivalent HPV hybridization probe, Digene Hybrid Capture II (Gaithersburg, MD), which recognizes high-risk types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and 68, was used to determine the HPV infection status of the cytologic specimens, and the endoscopic biopsies were used to classify each subject's esophageal disease. 740 subjects completed the cytologic and endoscopic exams, and 702 had adequate cytologic and biopsy specimens. Using a cutpoint of > or =3.0 pg/ml of HPV DNA to define a positive test, HPV positivity was identified in 13% (61/475) of subjects without squamous dysplasia, 8% (8/102) with mild dysplasia, 7% (6/83) with moderate dysplasia, 16% (6/38) with severe dysplasia and zero (0/4) with invasive ESCC. Changing the cutpoint defining a positive test did not change the association of HPV infection and dysplasia grade. In this high-risk population, infection of esophageal cells with high-risk HPV types occurs in 13% of asymptomatic adults with no evidence of squamous dysplasia and a similar proportion of individuals with mild, moderate or severe dysplasia. This suggests that HPV infection is not a major risk factor for ESCC in this high-risk Chinese population. Further studies are warranted to determine if infection with this agent is associated with neoplastic progression in a subset of cases.
