RESUMEN

Introduction: Patients are increasingly turning to other sources for their health information. Social media has become mainstream, and the easy access to online communities, health professionals, and shared experiences of other patients has made social media a place where many patients turn to. Methods: In this qualitative report, 2 patients who have had breast cancer describe the reasons why they use social media, what they perceive the advantages and disadvantages are, and what the impact of social media has been through their cancer treatment and beyond. Results: The reasons why patients turn to social media are varied. These can include information gathering, peer support, shared experiences, and advocacy. There appear to be advantages and disadvantages; however, overall, the impact seems to be a positive one when used judiciously. Discussion: It is clear that social media has a role to play in healthcare, whether by providing meaningful social connections, delivery of information, or psychological support. Healthcare professionals perhaps should consider the importance of social media in their practice.

RESUMEN

Introduction: Increasing evidence suggests that de-escalation of axillary surgery is safe, without significantly impacting patient outcome. Obtaining positive lymph nodes at a sentinel lymph node biopsy (SNB) can guide decisions toward the requirement of axillary nodal clearance (ANC). However, methods to predict how many further nodes will be positive are not available. This study investigates the feasibility of predicting the likelihood of a negative ANC based on the ratio between positive nodes and the total number of lymph nodes excised at SNB. Methods: Retrospective data from January 2017 to March 2022 was collected from electronic medical records. Patients with oestrogen receptor (ER) positive and HER2 negative receptor disease were included in the study. ER-negative and HER2-positive disease was excluded, alongside patients who had chemotherapy before ANC. Results: Of 102 patients, 58.8% (n=60) had no macrometastasis at ANC. On average, 2.76 lymph nodes were removed at SNB. A higher SNB ratio of positive to total nodes [OR 11.09 (CI 95% 2.33-52.72), P=0.002] had a significant association with positive nodes during ANC. SNB ratio less than or equal to 0.33 (1/3) had a specificity of 79.2% in identifying cases that later had a negative completion ANC, with a 95.8% specificity of no further upgrade of nodal staging. Conclusion: A low SNB ratio of less than 0.33 (1/3) has a high specificity in excluding the upgradation of nodal staging on completion of ANC, with a false-negative rate of less than 5%. This may be used to identify patients with a low risk of axillary metastasis, who can avoid ANC.

RESUMEN

BACKGROUND: It is not well understood the overall changes that multidisciplinary teams (MDTs) have had to make in response to the COVID-19 pandemic, nor the impact that such changes, in addition to the other challenges faced by MDTs, have had on decision-making, communication, or participation in the context of MDT meetings specifically. METHODS: This was a mixed method, prospective cross-sectional survey study taking place in the United Kingdom between September 2020 and August 2021. RESULTS: The participants were 423 MDT members. Qualitative findings revealed hybrid working and possibility of virtual attendance as the change introduced because of COVID-19 that MDTs would like to maintain. However, IT-related issues, slower meetings, longer lists and delays were identified as common with improving of the IT infrastructure necessary going forward. In contrast, virtual meetings and increased attendance/availability of clinicians were highlighted as the positive outcomes resulting from the change. Quantitative findings showed significant improvement from before COVID-19 for MDT meeting organisation and logistics (M = 45, SD = 20) compared to the access (M = 50, SD = 12, t(390) = 5.028, p = 0.001), case discussions (M = 50, SD = 14, t(373) = -5.104, p = 0.001), and patient representation (M = 50, SD = 12, t(382) = -4.537, p = 0.001) at MDT meetings. DISCUSSION: Our study explored the perception of change since COVID-19 among cancer MDTs using mixed methods. While hybrid working was preferred, challenges exist. Significant improvements in the meeting organisation and logistics were reported. Although we found no significant perceived worsening across the four domains investigated, there was an indication in this direction for the case discussions warranting further 'live' assessments of MDT meetings.

RESUMEN

BACKGROUND: Multidisciplinary teams (MDTs) are widely used in cancer care. Recent research points to logistical challenges impeding MDT decision-making and dissatisfaction among members. This study sought to identify different types of logistical issues and how they impacted team processes. METHODS: This was a secondary analysis of a cross-sectional observational study. Three cancer MDTs (breast, colorectal, and gynaecological) were recruited from UK hospitals. Validated observational instruments were used to measure decision-making (Metrics of Observational Decision-making, MDT-MODe), communication (Bales' Interaction Process Analysis, Bales' IPA), and case complexity (Measure of Case Discussion Complexity, MeDiC), including logistical challenges (Measure of Case Discussion Complexity, MeDiC), across 822 case discussions from 30 videoed meetings. Descriptive analysis and paired samples t tests were used to identify and compare frequency of different types of logistical challenges, along with partial correlations, controlling for clinical complexity of cases, to understand how such issues related to the MDT decision-making and communication. RESULTS: A significantly higher frequency of administrative and process issues (affecting 30 per cent of cases) was seen compared with the frequency of equipment issues (affecting 5 per cent of cases; P < 0.001) and the frequency of the attendance issues (affecting 16 per cent of cases; P < 0.001). The frequency of the attendance issues was significantly higher than the frequency of equipment issues (P < 0.001). Partial correlation analysis revealed that administrative and process issues, including attendance, were negatively correlated with quality of information (r = -0.15, P < 0.001; r = -0.11, P < 0.001), and equipment issues with the quality of contribution to meeting discussion (r = -0.14, P < 0.001). More questioning and answering by MDT members was evident with the administrative and process issues (r = 0.21, P < 0.001; r = 0.19, P < 0.001). Some differences were observed in teams' socioemotional reactions to the administrative and process issues with the gynaecological MDT showing positive correlation with positive socioemotional reactions (r = 0.20, P < 0.001), and the breast cancer MDT with negative socioemotional reactions (r = 0.17, P < 0.001). CONCLUSION: Administrative and process issues were the most frequent logistical challenges for the studied teams. Where diagnostic results were unavailable, and inadequate patient details provided, the quality of decision-making was reduced.

RESUMEN

BACKGROUND: Multidisciplinary teams (MDT) formulate expert informed treatment recommendations for people with cancer. We set out to examine how the factors proposed by the functional perspective of group decision making (DM), that is, interaction process, internal factors (factors emanating from within the group such as group size), external circumstances (factors coming from the outside of the team), and case-complexity affect the quality of MDT decision making. METHODS: This was a cross-sectional observational study. Three cancer MDTs were recruited with 44 members overall and 30 of their weekly meetings filmed. Validated observational instruments were used to measure quality of DM, interactions, and complexity of 822 case discussions. RESULTS: The full regression model with the variables proposed by the functional perspective was significant, R2  = 0.52, F(20, 801) = 43.47, P < .001, adjusted R2  = 0.51. Positive predictors of DM quality were asking questions (P = .001), providing answers (P = .001), team size (P = .007), gender balance (P = .003), and clinical complexity (P = .001), while negative socioemotional reactions (P = .007), gender imbalance (P = .003), logistical issues (P = .001), time-workload pressures (P = .002), and time spent in the meeting (P = .001) were negative predictors. Second half of the meetings also saw significant decrease in the DM quality (P = .001), interactions (P = .001), group size (P = .003), and clinical complexity (P = .001), and an increase in negative socioemotional reactions (P = .001) and time-workload pressures (P = .001). DISCUSSION: To the best of our knowledge, this is the first study to attempt to assess the factors proposed by the functional perspective in cancer MDTs. One novel finding is the effect of sociocognitive factors on team DM quality, while another is the cognitive-catch 22 effect: while the case discussions are significantly simpler in the second half of the meeting, there is significantly less time left to discuss the remaining cases, further adding to the cognitive taxation in teams who are now rapidly attempting to close their time-workload gap. Implications are discussed in relation to quality and safety.

RESUMEN

BACKGROUND AND OBJECTIVE: There is increasing emphasis in cancer care globally for care to be reviewed and managed by multidisciplinary teams (ie, in tumor boards). Evidence and recommendations suggest that the complexity of each patient case needs to be considered as care is planned; however, no tool currently exists for cancer teams to do so. We report the development and early validation of such a tool. METHODS: We used a mixed-methods approach involving psychometric evaluation and expert review to develop the Measure of case-Discussion Complexity (MeDiC) between May 2014 and November 2016. The study ran in six phases and included ethnographic interviews, observations, surveys, feasibility and reliability testing, expert consensus, and multiple expert-team reviews. RESULTS: Phase-1: case complexity factors identified through literature review and expert interviews; Phase-2: 51 factors subjected to iterative review and content validation by nine cancer teams across four England Trusts with nine further items identified; Phase 3: 60 items subjected to expert review distilled to the most relevant; Phase 4: item weighing and further content validation through a national UK survey; Phases 5 and 6: excellent interassessor reliability between clinical and nonclinical observers, and adequate validity on 903 video case discussions achieved. A final set of 27 factors, measuring clinical and logistical complexities were integrated into MeDiC. CONCLUSIONS: MeDiC is an evidence-based and expert-driven tool that gauges the complexity of cancer cases. MeDiC may be used as a clinical quality assurance and screening tool for tumor board consideration through case selection and prioritization.

RESUMEN

Introduction Breast cancer remains the most common cancer diagnosis in the UK. The current clinical practice utilises two different types of modalities to estimate the prognosis, risk of recurrence and benefit from adjuvant chemotherapy treatment in patients with early breast cancer. The first set of modalities includes risk calculators based on clinicopathological features, e.g. PREDICT or the Nottingham Prognostic Index (NPI); the second includes genetic profiling of tumour tissue using Oncotype DX (ODX; Genomic Health, Redwood City, CA) testing. PREDICT, NPI and ODX stratify breast cancers into high-, intermediate- and low-risk categories to help guide adjuvant chemotherapy treatment decisions. This study compares PREDICT, NPI and ODX Recurrence Scores (RS), with the aim of assessing 1) the correlation between the RS for PREDICT, NPI and ODX and 2) whether early breast cancer patients are stratified into similar risk categories by all three modalities. Methods This retrospective study included early breast cancer patients treated at a National Health Service (NHS) hospital over a 12-month period (October 1, 2017 to September 30, 2018). Inclusion criteria: consecutive patients with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative and lymph node-negative breast cancer. All patients were discussed at the local multidisciplinary team (MDT) meeting and underwent ODX testing. Exclusion criteria: patients without ODX test scores; patients with an in-breast recurrence; patients who did not undergo a sentinel lymph node biopsy (SLNB); and patients with ductal carcinoma in situ (DCIS) only. NPI and PREDICT scores were calculated for each patient using online tools, and ODX data was obtained through Genomic Health and MDT records. Patients were risk-stratified into high, intermediate and low risk of recurrence groups based on their PREDICT, NPI and ODX scores. The thresholds for risk stratification were based on current practice, which is evidence-based. Correlations between PREDICT, NPI and ODX scores were analysed using Spearman's correlation coefficient. Results Forty-six patients (mean age: 56 years), with a total of 57 early breast cancers, underwent ODX testing. Risk categories generated by PREDICT very strongly correlated with NPI for all patients (r=0.92; P<0.0001). However, the RS generated by ODX testing only strongly correlated for patients with low-risk PREDICT scores (r=0.51; P=0.0134), while no correlation between RS and PREDICT was observed for patients with intermediate- or high-risk PREDICT scores (r=-0.0064; P=0.9767). Similar results were seen between NPI and RS. Overall, only 19/46 (41.3%) patients had an RS which corresponded to PREDICT risk category, while 18/46 (39.1%) patients had an RS that indicated a higher risk of recurrence than PREDICT, and 9/46 (19.6%) patients had an RS indicating a lower risk of recurrence than PREDICT. Similar results were found when comparing RS and NPI. Conclusion The risk of recurrence estimated by ODX in patients deemed low risk by PREDICT or NPI highly correlated, while no such correlation existed in patients with an estimated intermediate- or high-risk breast cancer. In PREDICT- or NPI-estimated intermediate- and high-risk patients, ODX provided valuable additional prognostic information to guide adjuvant treatment, while the potential avoidance of ODX testing in low-risk patients presents significant cost-savings.

RESUMEN

OBJECTIVE: The objective of this study was to examine effectiveness of codesigned quality-improving interventions with a multidisciplinary team (MDT) with high workload and prolonged meetings to ascertain: (1) presence and impact of decision-making (DM) fatigue on team performance in the weekly MDT meeting and (2) impact of a short meeting break as a countermeasure of DM fatigue. DESIGN AND INTERVENTIONS: This is a longitudinal multiphase study with a codesigned intervention bundle assessed within team audit and feedback cycles. The interventions comprised short meeting breaks, as well as change of room layout and appointing a meeting chair. SETTING AND PARTICIPANTS: A breast cancer MDT with 15 members was recruited between 2013 and 2015 from a teaching hospital of the London (UK) metropolitan area. MEASURES: A validated observational tool (Metric for the Observation of Decision-making) was used by trained raters to assess quality of DM during 1335 patient reviews. The tool scores quality of information and team contributions to reviews by individual disciplines (Likert-based scores), which represent our two primary outcome measures. RESULTS: Data were analysed using multivariate analysis of variance. DM fatigue was present in the MDT meetings: quality of information (M=16.36 to M=15.10) and contribution scores (M=27.67 to M=21.52) declined from first to second half of meetings at baseline. Of the improvement bundle, we found breaks reduced the effect of fatigue: following introduction of breaks (but not other interventions) information quality remained stable between first and second half of meetings (M=16.00 to M=15.94), and contributions to team DM improved overall (M=17.66 to M=19.85). CONCLUSION: Quality of cancer team DM is affected by fatigue due to sequential case review over often prolonged periods of time. This detrimental effect can be reversed by introducing a break in the middle of the meeting. The study offers a methodology based on 'team audit and feedback' principle for codesigning interventions to improve teamwork in cancer care.

RESUMEN

Isolated amyloidomas derived from insulin are extremely rare, and there is only one reported case to date of insulin-derived amyloidoma in the breast.We present the case of a 36-year-old woman reporting a lump in the right breast. It was clinically assessed as a probable fibroadenoma but was removed surgically given the size of the lesion. On histological analysis, the lesion had features consistent with amyloid. Further investigations showed the amyloid to be derived from insulin. The lump was removed in its entirety, and the patient made a full recovery.

RESUMEN

A 73-year-old man with gallstone disease was admitted with right upper quadrant abdominal pain. He was treated for cholecystitis with intravenous antibiotics. Two days later, he reported of new onset left iliac fossa pain, with tenderness and guarding. An abdominal X-ray demonstrated small bowel obstruction, a CT scan demonstrated an impacted gallstone within the proximal ileum. He was treated for a gallstone ileum and underwent an uncomplicated laparotomy, small bowel enterotomy and removal of a faceted gallstone. Three months later, the patient re-presented with generalised abdominal pain, guarding and rebound tenderness. Small bowel obstruction was again demonstrated with an impacted gallstone within the distal ileum seen on CT scan. A second laparotomy revealed two further faceted gallstones, which were removed through an enterotomy. The densely adherent gallbladder to the duodenum precluded a surgical repair of the cholecystoduodenal fistula. He made an uneventful recovery and was subsequently discharged home.

RESUMEN

The posterior aspect of the pancreatic head has proven to be a technically demanding region to approach laparoscopically. Previously, this region was approached through the gastrocolic ligament with the patient in a left semilateral position. We believe that this makes the laparoscopic approach to the posterior pancreatic head extremely difficult. In the technique presented here, which has been successfully used in 4 patients, the patient was in full left lateral position, and Nathanson retractors were used to retract the liver and right kidney. This allowed full exposure of the second part of the duodenum before any major dissection. The duodenum was then Kocherized, and the posterior aspect of the pancreatic head, along with the inferior vena cava, left renal vein, and aorta, was exposed. We describe here a safe and feasible laparoscopic method for access to and management of lesions related to the posterior aspect of the pancreatic head.

RESUMEN

Transcriptional silencing by CpG island hypermethylation is a potential mechanism for the inactivation of tumor-related genes. Virtually, all types of human cancers show CpG island hypermethylation, and gastric carcinoma (GC) is one of the tumors with a high frequency of aberrant CpG island hypermethylation. In this study, we prescreened DNA methylation of 170 CpG island loci in a training set of 8 paired GC and GC-associated non-neoplastic mucosae (GCN) using MethyLight technology and selected 27 DNA methylation markers showing higher methylation frequency or level in GC than in GCN. These markers were then analyzed in a tester set of 25 paired GC and GCN and 27 chronic gastritis (CG) from non-cancer patients to generate their DNA methylation profiles. We identified 17 novel methylation markers in GC, including SFRP4, SEZ6L, TWIST1, BCL2, KL, TERT, SCGB3A1, IGF2, GRIN2B, SFRP5, DLEC1, HOXA1, CYP1B1, SMAD9, MT1G, NR3C1, and HOXA10. Of the 27 selected CpG island loci, 23 were methylated in GC, GCN, and CG and the remainder four loci (DLEC1, CHFR, CYP1B1, and NR3C1) were only methylated in GC. We found that the number of methylated loci was significantly higher in GC than in GCN or CG and that Helicobacter pylori infection was strongly associated with aberrant CpG island hypermethylation in CG. Hypermethylation was more prevalent in Epstein-Barr virus (EBV)-positive GC than in EBV-negative GC and in diffuse-type GC than in intestinal-type GC. Through our large-scale screening of 170 CpG island loci, we found 17 new DNA methylation markers of GC, which may serve as useful markers that may identify a distinct subset of GC.

RESUMEN

BACKGROUND: Surgery, as the mainstay of treatment for localized esophageal cancer, is currently being challenged by the assumed high risk of esophagectomy and the poor longterm survival after resection. Epidemiologic and clinical changes over the past decade indicate that these assumptions should be reevaluated. The aim of this study was to assess the modern outcomes of esophagectomy for adenocarcinoma. STUDY DESIGN: We studied 263 consecutive patients (215 men, 48 women), who had esophagectomy for adenocarcinoma from 1992 to 2002. Ninety-seven (37%) were stage I, 63 (24%) were stage II, 93 (35%) were stage III, and 10 (4%) were stage IV. Forty-five percent (119 of 263) had curative en bloc resection, 52% (138 of 263) had node involvement, and 18% (48) received neoadjuvant therapy. RESULTS: Seventeen percent (44 of 263) of the patients were identified in a Barrett's surveillance program. The frequency of T1N0 adenocarcinoma increased over the study period (p=0.024). The overall 5-year survival was 46.5%, and for the last 5 years of the study was 50.4%. The overall 5-year survival for stage I was 81%; for stage II, 51%; for stage III, 14%; and for stage IV, 0%. Complications occurred in 61% and there were 12 perioperative deaths (4.5%). Cox proportional hazard analysis identified tumor stage and type of resection as independent predictors of survival. CONCLUSIONS: Nearly half of patients undergoing esophagectomy for adenocarcinoma survive >or=5 years. Improvements in survival are associated with increased detection of early stage disease, and a liberal use of en bloc resection. Nonsurgical treatments should be compared with these contemporary outcomes measures.

RESUMEN

BACKGROUND: The incidence of adenocarcinoma in the distal esophagus and at the gastroesophageal junction (GEJ) has been increasing in the last decades. It has been suggested that patients in whom Barrett mucosa can be identified in the surgical specimen have a better prognosis compared with those without. This has led to the belief that patients with and without Barrett mucosa may represent 2 distinct cancer types. HYPOTHESIS: Distal esophageal-GEJ adenocarcinoma with and without Barrett mucosa share the same origin, but differ only in clinical presentation and outcome. DESIGN AND SETTING: Retrospective cohort study in a university tertiary referral center. PATIENTS AND METHODS: Between 1992 and 2002, 215 patients (173 men and 42 women; median age, 66 years; age range, 26-91 years) had esophagogastrectomy for adenocarcinoma of the distal esophagus-GEJ. Patients receiving neoadjuvant chemotherapy or radiation therapy were excluded. MAIN OUTCOME MEASURES: Clinical presentation, tumor characteristics, and survival were compared in patients with Barrett mucosa (n = 140) and those without (n = 75). RESULTS: Patients with Barrett mucosa in the specimen had tumors that were diagnosed earlier; were smaller in size; earlier in stage, with fewer node metastases; and had a better 5-year survival. CONCLUSIONS: Observed differences in survival between patients with distal esophageal-GEJ adenocarcinoma with and without Barrett mucosa can be explained by earlier diagnosis. Patients without Barrett mucosa have their tumors detected later, when the disease is more advanced. This suggests the possibility that tumors without Barrett mucosa are not of a different origin, but rather are larger tumors that may have overgrown areas of Barrett mucosa.
