Objective: To examine the association between the performance of mapping biopsies and surgical outcomes postexcision of extramammary Paget's disease (EMPD)., Background: Primary EMPD is a rare entity associated with poorly defined surgical margins and difficult-to-access sites of lesions. Surgical resection with clear margins remains the preferred management method. The use of mapping biopsies might be beneficial, particularly in lowering disease recurrence., Methods: Available literature was reviewed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology before a fixed-effect meta-analysis was performed to identify the presence of a correlation between performing mapping biopsies and positive margins on permanent sections as well as disease-free survival. Additional study results not included in the quantitative assessment were qualitatively assessed and reported., Results: A total of 12 studies were shortlisted for final analysis. 294 patients who underwent mapping biopsies and 48 patients who did not undergo mapping biopsies were included in the assessment. Forest plot analysis revealed a pooled rate ratio of 0.50 (95% CI, 0.32-0.77) in the prevalence of positive margins in patients with mapping biopsies performed as compared to patients without. The pooled rate ratio of the prevalence of disease-free survival in patients with mapping biopsies performed as compared to patients without was 1.38 (95% CI, 1.03-1.84). Qualitative assessment of the remaining selected studies revealed equivocal results., Conclusions: Mapping biopsies are able to improve EMPD surgical excision outcomes but given the rarity of the disease and heterogeneity of mapping biopsy procedures, further confirmation with randomized controlled trials or a larger patient pool is necessary., (Copyright © 2023 The Author(s).

To evaluate the trajectories and sustainability of health-related quality of life (HRQoL) outcomes after palliative gastrointestinal (GI) surgery and perioperative factors associated with HRQoL improvement postsurgery., Background: Palliative patients face a wide range of physical, emotional, social, and functional challenges. In evaluating the efficacy of palliative surgical interventions, a major pitfall of traditional surgical outcome measures is that they fall short of measuring outcomes that are meaningful to patients during end-of-life. HRQoL tools may provide a more comprehensive assessment of the true value and impact of palliative surgery., Methods: We prospectively recruit advanced cancer patients undergoing palliative GI surgery. The Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire was administered before and at regular intervals after surgery. HRQoL improvement was defined as ≥4-points increment in FACT-G total score over baseline. Duration of sustained HRQoL improvement above this threshold and factors associated with varying extents of HRQoL change were evaluated., Results: Of the 65 patients, intestinal obstruction was the most common indication for surgery (70.8%). The mean baseline FACT-G total score was 70.7 (95% CI: 66.3-75.1). Forty-six (70.8%) patients experienced HRQoL improvement after surgery. This HRQoL improvement was sustained over a median duration of 3.5 months and was driven mainly by improvements in patients' physical and emotional well-being. Albumin was significantly associated with the extent of HRQoL improvements ( P = 0.043)., Conclusion: A clinically significant and sustained improvement in HRQoL was observed after palliative GI surgery. Patients with higher preoperative albumin levels were more likely to experience HRQoL improvements., Competing Interests: The authors declare that there is no conflict of interest., (Copyright © 2022 The Author(s).
