Diagnostic accuracy and economic impact of three work-up strategies identifying risk groups in endometrial cancer, fully incorporating sentinel lymph node algorithm.

BACKGROUND: According to the European Society for Medical Oncology/ European Society of Gynaecological Oncology/European Society for Radiotherapy and Oncology (ESMO/ESGO/ESTRO) Consensus Conference, the role of preoperative risk groups (RGs) in endometrial cancer (EC) is to direct surgical nodal staging. We compared diagnostic accuracy and economic impact of three work-up strategies to identify RGs. METHODS: A retrospective multicentre study including patients with early-stage EC. The three different work-up strategies were as follows:-Mondovì Hospital: transvaginal ultrasonography, pelvic magnetic resonance imaging (MRI); frozen section examination of the uterus in case of imaging discordance. High-risk patients underwent abdominal computed tomography.-Gemelli Hospital: transvaginal ultrasonography, MRI, One-Step Nucleic Acid Amplification (OSNA) of sentinel lymph node (SLN); frozen section examination of the uterus in case of imaging discordance.-Negrar Hospital: positron emission tomography (PET), frozen section examination of the uterus and of SLN. For statistical purposes patients were assigned, preoperatively and postoperatively, to two groups: group A (high-risk) and group B (not high-risk). RESULTS: Three hundred eighty-five patients were included (93 Mondovì, 215 Gemelli, 77 Negrar). Endometrial biopsy errors led to 47.3% misclassifications. Test accuracy of Mondovì, Gemelli and Negrar strategies was 0.83 (95%CI 0.734-0.901), 0.95 (95%CI 0.909-0.975) and 0.94 (95%CI 0.866-0.985), respectively. Preoperative work-up mean cost per patient in group A was €514.5 at Mondovì, €868.5 at Gemelli, and €1212.8 at Negrar hospital (p-value < 0.001), while in group B was €378.8 at Mondovì, €941.2 at Gemelli, and €1848.4 at Negrar hospital (p-value < 0.001). CONCLUSIONS: In our study, work-up strategies with more relevant economic impact showed a better diagnostic accuracy. Upcoming guidelines should specify recommendations about the gold standard work-up strategy, including the role of SLN.

Comparison of minimally invasive surgery with laparotomic approach in the treatment of high risk endometrial cancer: A systematic review.

OBJECTIVE: To analyze all published studies comparing minimally invasive surgery (MIS) with laparotomic one in the surgical treatment of high-risk endometrial cancer (EC) in term of operative, peri-operative and oncological outcomes. DATA SOURCES: We conducted a systematic literature search in PubMed between January 1995-March 2019. METHODS OF STUDY SELECTION: Titles and abstracts were analyzed by two reviewers. A set of explicit criteria was used for selection of literature: 1) randomized controlled trials (RCT), prospective or retrospective cohort studies, given the rarity of this tumor and the concomitant lack of data in the form of large trials, all reviewed original report publications with an appropriate number of subjects were considered and included; 2) participants of interest being patients who have suffered from high risk EC 3) the outcome measures including overall survival (OS), disease-free survival (DFS) and recurrence, (4) English language, (5) abstract available. RESULTS: Thirty relevant articles were selected for full reading. For final analysis 20 studies were selected. Then, as second step, the full articles were evaluated to determine whether full inclusion criteria were met. In total, 9 papers were identified and included. CONCLUSION: MIS appears to be safe in the management of high-risk EC patients, showing better perioperative and postoperative outcomes and comparable oncological outcomes than open surgery. Prospective randomized trial would be needed to confirm this data.

Cephalosporin-induced Hemolytic Anemia in a Sicilian Child.

A 27-month-old child developed acute hemolysis on two occasions after the administration of cephalosporin. On the first occasion, hemolysis was intravascular and was due to the formation of complexes between antibodies and the drug, which bound to red blood cells and caused severe hemolysis. On the second occasion, hemolysis was extravascular and was probably due to antibody-dependent cell mediated cytotoxicity. Marked increases in levels of CD19(+), and CD57(+) CD8(+) cells were detected among the subpopulations of the patient's lymphocytes but only in the level of CD19(+) cells from the patient's father, after incubation of a sample of whole blood with a solution of cephalosporins. These results might explain the differences between the immune response of the patient and those of other members of his family and of an unrelated control.

Cephalosporin-induced Hemolytic Anemia in a Sicilian Child; Erythropoiesis.

A 27-month-old child developed acute hemolysis on two occasions after the administration of cephalosporin. On the first occasion, hemolysis was intravascular and was due to the formation of complexes between antibodies and the drug, which bound to red blood cells and caused severe hemolysis. On the second occasion, hemolysis was extravascular and was probably due to antibody-dependent cell-mediated cytotoxicity. Marked increases in levels of CD(19) (+) and CD(57) (+) CD(8) (+) cells were detected among the subpopulations of the patient's lymphocytes but only in the level of CD(19) (+) cells from the patient's father, after incubation of a sample of whole blood with a solution of cephalosporins. These results might explain the differences between the immune response of the patient and those of other members of his family and of an unrelated control.

Hemophilia: pathophysiology and musculoskeletal complications.

By its nature, hemophilia and its complications are ideally suited to the team-care approach. This paper reviews the pathophysiology of hemophilia and its concomitant musculoskeletal involvement, and discusses the approach and contributions of various disciplines.
