RESUMEN
BACKGROUND: Effective mentorship is an important component of medical education with benefits to all stakeholders. In recent years, conceptualization of mentorship has gone beyond the traditional dyadic experienced mentor-novice mentee relationship to include group and peer mentoring. Existing theories of mentorship do not recognize mentoring's personalized, evolving, goal-driven, and context-specific nature. Evidencing the limitations of traditional cause-and-effect concepts, the purpose of this review was to systematically search the literature to determine if mentoring can be viewed as a complex adaptive system (CAS). METHODS: A systematic scoping review using Krishna's Systematic Evidence-Based Approach was employed to study medical student and resident accounts of mentoring and CAS in general internal medicine and related subspecialties in articles published between 1 January 2000 and 31 December 2023 in PubMed, Embase, PsycINFO, ERIC, Google Scholar, and Scopus databases. The included articles underwent thematic and content analysis, with the themes identified and combined to create domains, which framed the discussion. RESULTS: Of 5,704 abstracts reviewed, 134 full-text articles were evaluated, and 216 articles were included. The domains described how mentoring relationships and mentoring approaches embody characteristics of CAS and that mentorship often behaves as a community of practice (CoP). Mentoring's CAS-like features are displayed through CoPs, with distinct boundaries, a spiral mentoring trajectory, and longitudinal mentoring support and assessment processes. CONCLUSION: Recognizing mentorship as a CAS demands the rethinking of the design, support, assessment, and oversight of mentorship and the role of mentors. Further study is required to better assess the mentoring process and to provide optimal training and support to mentors.

BACKGROUND: Reviewing experiences and recognizing the impact of personal and professional views and emotions upon conduct shapes a physician's professional and personal development, molding their professional identity formation (PIF). Poor appreciation on the role of reflection, shortages in trained tutors and inadequate 'protected time' for reflections in packed medical curricula has hindered its integration into medical education. Group reflection could be a viable alternative to individual reflections; however, this nascent practice requires further study. METHODS: A Systematic Evidence Based Approach guided Systematic Scoping Review (SSR in SEBA) was adopted to guide and structure a review of group reflections in medical education. Independent searches of articles published between 1st January 2000 and 30th June 2022 in bibliographic and grey literature databases were carried out. Included articles were analysed separately using thematic and content analysis, and combined into categories and themes. The themes/categories created were compared with the tabulated summaries of included articles to create domains that framed the synthesis of the discussion. RESULTS: 1141 abstracts were reviewed, 193 full-text articles were appraised and 66 articles were included and the domains identified were theories; indications; types; structure; and benefits and challenges of group reflections. CONCLUSIONS: Scaffolded by current approaches to individual reflections and theories and inculcated with nuanced adaptations from other medical practices, this SSR in SEBA suggests that structured group reflections may fill current gaps in training. However, design and assessment of the evidence-based structuring of group reflections proposed here must be the focus of future study.

Evolving individual, contextual, organizational, interactional and sociocultural factors have complicated efforts to shape the professional identity formation (PIF) of medical students or how they feel, act and think as professionals. However, an almost exclusive reliance on online learning during the COVID-19 pandemic offers a unique opportunity to study the elemental structures that shape PIF and the environmental factors nurturing it. We propose two independent Systematic Evidence-Based Approach guided systematic scoping reviews (SSR in SEBA)s to map accounts of online learning environment and netiquette that structure online programs. The data accrued was analysed using the clinically evidenced Krishna-Pisupati Model of Professional Identity Formation (KPM) to study the evolving concepts of professional identity. The results of each SSR in SEBA were evaluated separately with the themes and categories identified in the Split Approach combined to create richer and deeper 'themes/categories' using the Jigsaw Perspective. The 'themes/categories' from each review were combined using the Funnelling Process to create domains that guide the discussion. The 'themes/categories' identified from the 141 included full-text articles in the SSR in SEBA of online programs were the content and effects of online programs. The themes/categories identified from the 26 included articles in the SSR in SEBA of netiquette were guidelines, contributing factors, and implications. The Funnelling Process identified online programs (encapsulating the content, approach, structures and the support mechanisms); their effects; and PIF development that framed the domains guiding the discussion. This SSR in SEBA identifies the fundamental elements behind developing PIF including a structured program within a nurturing environment confined with netiquette-guided boundaries akin to a Community of Practice and the elemental aspect of a socialisation process within online programs. These findings ought to be applicable beyond online training and guide the design, support and assessment of efforts to nurture PIF.

INTRODUCTION: Despite advances in diagnosis and management, patients with advanced pheochromocytomas and paragangliomas (PPGL) face limited treatment options. This study aims to evaluate the safety and efficacy of peptide receptor radionuclide therapy (PRRT) in patients with advanced PPGL, based on a single-institution experience and provide a comprehensive review of the literature. METHODS: A retrospective analysis was conducted on patients with advanced pheochromocytoma and paraganglioma who received PRRT at a single institution from April 2012 to March 2022. Clinical characteristics, treatment response, adverse events, and survival outcomes were assessed. A systematic literature review was also performed. RESULTS: A total of 15 patients with advanced PPGL were included, the majority of whom had both metastatic and functional disease. Most patients received four infusions of 177Lu-DOTATATE (73%). The median therapeutic 177Lu-DOTATATE radioactivity for each infusion was 7.4 GBq. Only one patient was treated with one infusion of 90Y-DOTATATE (4.2 GBq) in addition to three infusions of Lu-177 DOTATATE. Overall, PRRT suggests a promising efficacy with disease control rate of 63.6% by RECIST v1.1. The median overall survival (OS) was not reached and the median progression free survival (PFS) was 25.9 months. In terms of safety, PRRT was well tolerated. Review of the literature revealed consistent findings, supporting the efficacy and safety of PRRT in PPGL. CONCLUSION: This study suggests that PRRT is a safe and effective therapeutic option for patients with PPGL. Our findings align with the existing literature, providing additional evidence to support the use of PRRT in this challenging patient population.

ABSTRACT: We present a case of a 68-year-old man with metastatic small bowel neuroendocrine tumor who underwent 4 cycles of peptide receptor radionuclide therapy with 177 Lu-DOTATATE. For his first 3 cycles, therapy was performed approximately 4 weeks after his last dose of octreotide LAR. Because of miscommunication in scheduling, his fourth cycle was performed only 48 hours after his last full dose of octreotide LAR. Despite this, we found that the tumoral uptake was not reduced at all, which may add to the increasing evidence on the nonnecessity of stopping somatostatin analogs before peptide receptor radionuclide therapy.

BACKGROUND: Medical education has enjoyed mixed fortunes nurturing professional identity formation (PIF), or how medical students think, feel and act as physicians. New data suggests that structured mentoring programs like the Palliative Medicine Initiative (PMI) may offer a means of developing PIF in a consistent manner. To better understand how a well-established structured research mentoring program shapes PIF, a study of the experiences of PMI mentees is proposed. METHODOLOGY: Acknowledging PIF as a sociocultural construct, a Constructivist approach and Relativist lens were adopted for this study. In the absence of an effective tool, the Ring Theory of Personhood (RToP) and Krishna-Pisupati Model (KPM) model were used to direct this dual Systematic Evidence-Based Approach (Dual-SEBA) study in designing, employing and analysing semi-structured interviews with PMI mentees and mentoring diaries. These served to capture changes in PIF over the course of the PMI's mentoring stages. Transcripts of the interviews and mentoring diaries were concurrently analysed using content and thematic analysis. Complementary themes and categories identified from the Split Approach were combined using the Jigsaw Approach and subsequently compared with mentoring diaries in the Funnelling Process. The domains created framed the discussion. RESULTS: A total of 12 mentee interviews and 17 mentoring diaries were analysed, revealing two domains-PMI as a Community of Practice (CoP) and Identity Formation. The domains confirmed the centrality of a structured CoP capable of facilitating longitudinal mentoring support and supporting the Socialisation Process along the mentoring trajectory whilst cultivating personalised and enduring mentoring relationships. CONCLUSION: The provision of a consistent mentoring approach and personalised, longitudinal mentoring support guided along the mentoring trajectory by structured mentoring assessments lay the foundations for more effective mentoring programs. The onus must now be on developing assessment tools, such as a KPM-based tool, to guide support and oversight of mentoring relationships.

BACKGROUND: Mentoring plays a pivotal yet poorly understood role in shaping a physician's professional identity formation (PIF) or how they see, feel and act as professionals. New theories posit that mentoring nurtures PIF by functioning as a community of practice through its structured approach and its support of a socialisation process made possible by its assessment-directed personalized support. To test this theory and reshape the design, employ and support of mentoring programs, we evaluate peer-mentor experiences within the Palliative Medicine Initiative's structured research mentoring program. METHODS: Semi-structured interviews with peer mentors under the Palliative Medicine Initiative (PMI) at National Cancer Centre Singapore were conducted and triangulated against mentoring diaries to capture longitudinal data of their PMI experiences. The Systematic Evidence-Based Approach (SEBA) was adopted to enhance the trustworthiness of the data. SEBA employed concurrent content and thematic analysis of the data to ensure a comprehensive review. The Jigsaw Perspective merged complementary themes and categories identified to create themes/categories. The themes/categories were compared with prevailing studies on mentoring in the Funnelling Process to reaffirm their accuracy. RESULTS: Twelve peer-mentors participated in the interviews and eight peer-mentors completed the mentoring diaries. The domains identified were community of practice and identity work. CONCLUSIONS: The PMI's structured mentoring program functions as a community of practice supporting the socialisation process which shapes the peer-mentor's belief system. Guided by a structured mentoring approach, stage-based assessments, and longitudinal mentoring and peer support, peer-mentors enhance their detection and evaluation of threats to their regnant belief system and adapt their self-concepts of identity and personhood to suit their context. These insights will help structure and support mentoring programs as they nurture PIF beyond Palliative Medicine.

BACKGROUND: Reflective writing (RW) allows physicians to step back, review their thoughts, goals and actions and recognise how their perspectives, motives and emotions impact their conduct. RW also helps physicians consolidate their learning and boosts their professional and personal development. In the absence of a consistent approach and amidst growing threats to RW's place in medical training, a review of theories of RW in medical education and a review to map regnant practices, programs and assessment methods are proposed. METHODS: A Systematic Evidence-Based Approach guided Systematic Scoping Review (SSR in SEBA) was adopted to guide and structure the two concurrent reviews. Independent searches were carried out on publications featured between 1st January 2000 and 30th June 2022 in PubMed, Embase, PsychINFO, CINAHL, ERIC, ASSIA, Scopus, Google Scholar, OpenGrey, GreyLit and ProQuest. The Split Approach saw the included articles analysed separately using thematic and content analysis. Like pieces of a jigsaw puzzle, the Jigsaw Perspective combined the themes and categories identified from both reviews. The Funnelling Process saw the themes/categories created compared with the tabulated summaries. The final domains which emerged structured the discussion that followed. RESULTS: A total of 33,076 abstracts were reviewed, 1826 full-text articles were appraised and 199 articles were included and analysed. The domains identified were theories and models, current methods, benefits and shortcomings, and recommendations. CONCLUSIONS: This SSR in SEBA suggests that a structured approach to RW shapes the physician's belief system, guides their practice and nurtures their professional identity formation. In advancing a theoretical concept of RW, this SSR in SEBA proffers new insight into the process of RW, and the need for longitudinal, personalised feedback and support.

BACKGROUND: A socioculturally appropriate appreciation of dignity is pivotal to the effective provision of care for dying patients. Yet concepts of dignity remain poorly defined. To address this gap in understanding and enhance dignity conserving end-of-life care, a review of current concepts of dignity is proposed. METHODS: To address its primary research question "How do patients conceive the concept of dignity at the end of life?", this review appraises regnant concepts and influences of dignity, and evaluates current dignity conserving practices. To enhance accountability, transparency and reproducibility, this review employs the Ring Theory of Personhood (RToP) as its theoretical lens to guide a Systematic Evidence Based Approach guided Systematic Scoping Review (SSR in SEBA) of patient perspectives of dignity. Three independent teams of reviewers independently analysed included articles from a structured search of PubMed, Embase, PsycINFO, Scopus, CINAHL and Cochrane Databases using thematic and content analyses. The themes and categories identified were compared and combined using the Funnelling Process to create domains that guide the discussion that follows. RESULTS: Seventy-eight thousand five hundred seventy-five abstracts were identified, 645 articles were reviewed, and 127 articles were included. The three domains identified were definitions of dignity, influences upon perceptions of dignity, and dignity conserving care. CONCLUSIONS: This SSR in SEBA affirms the notion that dignity is intimately entwined with self-concepts of personhood and that effective dignity conserving measures at the end of life must be guided by the patient's concept of dignity. This SSR in SEBA posits that such personalised culturally sensitive, and timely support of patients, their family and loved ones may be possible through the early and longitudinal application of a RToP based tool.

ABSTRACT: Anastomosing hemangioma (AH) is a rare benign vascular lesion that primarily involves the genitourinary tract. Cases have also rarely been reported in other organs. AH is often discovered incidentally and resembles angiosarcoma histologically. On imaging, it may mimic other vascular lesions such as renal cell carcinoma and neuroendocrine tumors. We present a case of a 32-year-old woman with incidentally detected AH involving the kidneys, adrenal glands, liver, and retroperitoneum, initially presumed to be neuroendocrine tumors based on imaging findings on CT and 68Ga-DOTATATE PET scans.

BACKGROUND: Concepts of moral distress (MD) among physicians have evolved and extend beyond the notion of psychological distress caused by being in a situation in which one is constrained from acting on what one knows to be right. With many accounts involving complex personal, professional, legal, ethical and moral issues, we propose a review of current understanding of MD among physicians. METHODS: A systematic evidence-based approach guided systematic scoping review is proposed to map the current concepts of MD among physicians published in PubMed, Embase, PsycINFO, Web of Science, SCOPUS, ERIC and Google Scholar databases. Concurrent and independent thematic and direct content analysis (split approach) was conducted on included articles to enhance the reliability and transparency of the process. The themes and categories identified were combined using the jigsaw perspective to create domains that form the framework of the discussion that follows. RESULTS: A total of 30 156 abstracts were identified, 2473 full-text articles were reviewed and 128 articles were included. The five domains identified were as follows: (1) current concepts, (2) risk factors, (3) impact, (4) tools and (5) interventions. CONCLUSIONS: Initial reviews suggest that MD involves conflicts within a physician's personal beliefs, values and principles (personal constructs) caused by personal, ethical, moral, contextual, professional and sociocultural factors. How these experiences are processed and reflected on and then integrated into the physician's personal constructs impacts their self-concepts of personhood and identity and can result in MD. The ring theory of personhood facilitates an appreciation of how new experiences create dissonance and resonance within personal constructs. These insights allow the forwarding of a new broader concept of MD and a personalised approach to assessing and treating MD. While further studies are required to test these findings, they offer a personalised means of supporting a physician's MD and preventing burn-out.

CONTEXT: Advanced colorectal cancer and its treatment can bring about challenges associated with psychological distress. OBJECTIVES: The primary aims of this study were to examine the feasibility and acceptability of a cognitive behavioral therapy (CBT)-based intervention to improve coping with the disease. The secondary aim is to evaluate preliminary intervention efficacy. METHODS: Patients with advanced colorectal cancer in Singapore (N = 60) were randomized to either receive a four-session CBT intervention immediately or be waitlisted. Intervention feasibility (i.e., recruitment and intervention adherence) and acceptability (i.e., participant satisfaction and cultural sensitivity) were assessed. Changes in psychological distress and self-efficacy were examined. RESULTS: The study successfully recruited the intended sample (mean age 61; 62% men). A proportion (12%) reported Hospital Anxiety and Depression Scale scores indicative of distress at baseline. Most (88%) completed all sessions. Participants reported high rates of satisfaction (97%), helpfulness (96%), and cultural sensitivity (95%) of the intervention. The intervention group did not show decrease in psychological distress; however, self-efficacy in cancer-related coping (information seeking: effect size [ES] = 0.64; 95% CI = 0.17, 0.85; coping with side effects: ES = 0.69; 95% CI = 0.33, 0.82; and maintaining positive attitude: ES = 0.45; 95% CI = 0.19, 0.79) increased in the intervention group compared with the waitlisted group. CONCLUSION: The CBT-based intervention was feasible and acceptable to patients in Singapore. There is no sufficient evidence to warrant a larger trial in this sample with low baseline distress. Future work should identify and target those who are most in need of support.

AIM: The survival benefit of using a non-cross resistant second-line chemotherapy in the third-line setting in metastatic gastroesophageal cancer is unproven. We evaluated the utility of third-line chemotherapy in patients treated at a single institution. METHODS: Between 2010 and 2014, efficacy and toxicity data of patients who received three or more lines of systemic therapies for metastatic gastroesophageal adenocarcinoma at the National Cancer Centre Singapore was retrospectively analyzed. RESULTS: Thirty-two (6%) patients received three or more lines of chemotherapy. The median age and ECOG performance status were 59 years (36-82) and 1 (0-2), respectively. Majority of patients (88%) had tumor located in the stomach and 13 patients (41%) had diffuse histology or poorly cohesive or signet ring cells. Four (12%) patients had HER2-positive disease. Prior therapy was platinum (100%), fluoropyrimidine (97%), taxane (63%), irinotecan (28%), anthracycline (13%) and ramucirumab (3%). Third-line therapy consisted of 24 (75%) monotherapy, 6 (19%) doublet, 1 (3%) triplet chemotherapy and 1 (3%) clinical trial. Monotherapy irinotecan (44%) was most common, followed by docetaxel (19%) and paclitaxel (9%). Of 22 patients evaluable for response, there was 1 (5%) partial response, 9 (41%) stable disease. Median overall survival was 18.3 weeks (4.3-65.1). Of 30 patients evaluable for toxicities, 17 (57%) experienced at least one grade 3 or 4 toxicities. CONCLUSION: The benefit of using non-cross resistant second-line regimens as third-line chemotherapy was small with moderate toxicity. Newer agents such as nivolumab or TAS-102 or clinical trial may be preferred.

BACKGROUND: Epidemiological evidence suggests there are differences in gastroenteropancreatic neuroendocrine neoplasm (GEPNEN) among population groups. We aimed to contribute to the current evidence by evaluating the clinicopathological characteristics of GEPNEN in a multi-ethnic Asian group. MATERIALS AND METHODS: This was a retrospective chart review of patients diagnosed with GEPNEN at a tertiary medical institution at Singhealth Outram Campus, Singapore, between 1995 and 2015. RESULTS: Two hundred ninety-five patients were included in the evaluation, comprising Chinese (74.6%), Malay (4.4%), Indian (9.5%) and other (11.5%) ethnic backgrounds. The median age at diagnosis was 59 years; 52.5% were males. Distribution of disease stage at diagnosis was: localised (42.4%), regional (15.3%) and distant (38.0%). The three most common primary tumour sites were located in the pancreas (38.6%), rectum (19.7%) and stomach (9.5%), which varied significantly with ethnic background and age at diagnosis. Malay patients were younger (median 42 years) at diagnosis than Chinese (60 years). Patients with an appendiceal neuroendocrine neoplasm (NEN) (48 years) were younger compared to oesophageal NEN (66 years). Disease stage correlated with primary tumour site and grade (p < 0.001). Median overall survival (OS) for all GEPNEN was 10.2 years. Age at diagnosis, disease stage and grading were prognostic factors of OS in multivariable analyses. CONCLUSION: Our findings correspond with other studies that focus on GEPNEN incidences in Asian countries, with the pancreas, rectum and stomach being the most common primary tumour sites. Our findings suggest racial differences in primary tumour site and age at diagnosis. Further prospective population-based registries are required to understand these epidemiological differences.

PURPOSE: To evaluate the maximum tolerated dose (MTD) and pharmacokinetic profile of a chronomodulated, dose-intensified regimen of capecitabine in combination with oxaliplatin (XELOX) in metastatic colorectal cancer (mCRC). METHODS: Patients (N = 18) with 0 or 1 line of prior chemotherapy received oxaliplatin 100 mg/m(2) on day 1 from 1400 to 1800 hours with escalating dose levels of capecitabine (2,500, 3,000, 3,500, 4,000, 4,500, and 5,000 mg) once daily taken at 2400 hours on days 1-5. Each cycle lasted 14 days. RESULTS: The MTD of capecitabine was 4,500 mg. Transaminitis and anemia were the commonest non-hematologic and hematologic toxicities, respectively. Toxicities were generally mild, with only five occurrences of grade 3 toxicity and none of grade 4. There were no dose-limiting toxicities, defined as specific grade 3 or 4 toxicities occurring in the first two cycles of treatment. The objective response rate was 33.3 %, and median overall survival was 16.3 months (95 % CI: 11.2-18.2 months). The maximum plasma concentration (C(max)) and area under plasma concentration-time curve from time 0 to infinity (AUC([0-∞])) of the capecitabine metabolites in our fixed-dosing chronomodulated regimen were comparable to values seen with comparably dose-intense regimens but associated with significantly reduced toxicity. CONCLUSIONS: Chronomodulated dose-intensified XELOX facilitates delivery of dose-intense treatment in mCRC with a favorable therapeutic index that is promising.

INTRODUCTION: Communication between patients and physicians is crucial in the disclosure of cancer diagnosis. Although westernisation of Asian societies has resulted in increased awareness of patient autonomy, the family continues to play an important influencing role in the disclosure process. Therefore, in this study, we aimed to characterise the experience of physicians with the disclosure of cancer diagnosis in a westernised Asian population. METHODS: Oncologists at a tertiary hospital were approached to participate in this study. Information pertaining to the extent and approach to disclosure was collated. Logistic regression analysis was performed to characterise factors pertaining to the willingness of physicians to fully disclose a diagnosis of cancer. RESULTS: In all, 25 oncologists (mean age 38 years; 72% men) responded to the survey. A majority of oncologists disclosed a cancer diagnosis directly to the patient over the first few visits. The main reason behind partial or non-disclosure was family objection. Ordinal logistic regression analysis showed that family resistance was the only significant predictor of reluctance to disclose a cancer diagnosis (p = 0.01). CONCLUSION: In this pilot study, contrary to previous reports, we found that oncologists were more likely to disclose a diagnosis of cancer to the patient first, that they do not accede fully to the family's request for non-disclosure and that family resistance was the only significant predictor of reluctance to disclose a diagnosis of cancer.

AIM: To analyze the outcome of patients who received concurrent capecitabine (Xeloda) and radiation (XRT) compared to the established concurrent 5-fluorouracil (5-FU) with radiation (5FU-RT) and fluoropyrimidine-based chemotherapy alone as adjuvant treatment in gastric cancers. METHODS: All patients with gastric cancers who received adjuvant treatment at the National Cancer Centre Singapore between 1996 and 2006 were reviewed. Treatment outcomes of patients who received XRT were compared with those who had 5FU-RT or chemotherapy alone as adjuvant therapy for gastric cancers. RESULTS: A total of 108 patients were reviewed. Median age at diagnosis was 60. The majority of the patients (64.8%) had advanced stage III and IV disease (with no distant metastasis). All except 4 patients had D2 gastrectomy. Twenty one patients (19.4%) had positive surgical resection margins. Thirty three patients received XRT compared with 52 who had 5FU-RT and 23 who received chemotherapy alone. For the patients in the chemotherapy-only group, all had fluoropyrimidine-based therapy, with added cisplatin in 7 patients and epirubicin in 2 patients. Median recurrence-free survival was longer for the XRT group (52 mo) compared to the 5FU-RT (35 mo) and chemotherapy-only groups (25 mo) (P = 0.48). The patients in the XRT group achieved similar median overall survival (53 mo) as the 5FU-RT (54 mo) and the chemotherapy-only groups (44 mo) (P = 0.5). CONCLUSION: Capecitabine with concurrent radiation was as effective as concurrent 5FU with radiation or fluoropyrimidine-based chemotherapy alone when used as adjuvant treatment in patients with gastric cancers.
