RESUMEN

BACKGROUND: Haematological ('blood') cancers are a diverse group of non-solid cancers with varying incidence, mortality and survival. While there is some evidence that Maori experience disparities in blood cancer outcomes relative to New Zealand's majority European population, there is a need for a comprehensive overview of the current state of evidence in this context. METHODS: Blood cancer registrations were derived from the NZ Cancer Registry for the 2007-2019 period (combined blood cancers: 2653 Maori, 20,458 Europeans), and linked to Mortality records. We calculated age-sex-standardised incidence and mortality rates, and conducted cancer-specific survival analysis, for four main categories of blood cancers (leukaemia, Hodgkin lymphoma, non-Hodgkin lymphoma and myeloma) as well as for sub-types of leukaemia non-Hodgkin lymphoma. RESULTS: We found that Maori are more likely to be diagnosed with (incidence) and to die from (mortality) both leukaemia and myeloma, and similarly likely to be diagnosed or die from Hodgkin and non-Hodgkin lymphoma, compared to Europeans. Maori had demonstrably poorer cancer-specific survival outcomes across most blood cancer types (age-sex-adjusted hazard ratios [HRs], Maori vs European: leukaemia 1.77, 95 % CI 1.57-2.00; Hodgkin lymphoma 1.18, 95 % CI 0.65-2.16; non-Hodgkin lymphoma 1.71, 95 % CI 1.50-1.95; myeloma 1.40, 95 % CI 1.19-1.64). CONCLUSION: Blood cancers are a common cancer type for Maori, and we found evidence of disparities in incidence, mortality and survival compared to Europeans. Further research is required to further pinpoint exactly where interventions should be aimed to reduce blood cancer incidence and address survival disparities for Maori.

RESUMEN

BACKGROUND: Emergency laparotomy has high morbidity and mortality rates. Frailty assessment remains underutilized in this setting, in part due to time constraints and feasibility. The Clinical Frailty Scale has been identified as the most appropriate tool for frailty assessment in emergency laparotomy patients and is recommended for all older patients undergoing emergency laparotomy. The prognostic impact of measured frailty using the Clinical Frailty Scale on short- and long-term mortality and morbidity rates remains to be determined. METHODS: Observational cohort studies were identified by systematically searching Medline, Embase, Scopus and CENTRAL databases up to February 2024, comparing outcomes following emergency laparotomy for frail and non-frail participants defined according to the Clinical Frailty Scale. The primary outcomes were short- and long-term mortality rates. A random-effects model was created with pooling of effect estimates and a separate narrative synthesis was created. Risk of bias was assessed. RESULTS: Twelve articles comprising 5704 patients were included. Frailty prevalence was 25% in all patients and 32% in older adults (age ≥55 years). Older patients with frailty had a significantly greater risk of postoperative death (30-day mortality rate OR 3.84, 95% c.i. 2.90 to 5.09, 1-year mortality rate OR 3.03, 95% c.i. 2.17 to 4.23). Meta-regression revealed that variations in cut-off values to define frailty did not significantly affect the association with frailty and 30-day mortality rate. Frailty was associated with higher rates of major complications (OR 1.93, 95% c.i. 1.27 to 2.93) and discharge to an increased level of care. CONCLUSION: Frailty is significantly correlated with short- and long-term mortality rates following emergency laparotomy, as well as an adverse morbidity rate and functional outcomes. Identifying frailty using the Clinical Frailty Scale may aid in patient-centred decision-making and implementation of tailored care strategies for these 'high-risk' patients, with the aim of reducing adverse outcomes following emergency laparotomy.

RESUMEN

BACKGROUND: Lung cancer is a deadly cancer. Early diagnosis and access to timely treatment are essential to maximizing the likelihood of survival. Indigenous peoples experience enduring disparities in lung cancer survival, and disparities in access to and through lung cancer services is one of the important drivers of these disparities. In this manuscript, we aimed to examine the current evidence on disparities in Indigenous access to services along the lung cancer treatment pathway. METHODS: A narrative literature review was conducted for all manuscripts and reports published up until July 20, 2022, using Medline, Scopus, Embase, and Web of Science. Following the identification of eligible literature, full-text versions were scanned for relevance for inclusion in this review, and relevant information was extracted. After scanning 1,459 documents for inclusion, our final review included 36 manuscripts and reports that included information on lung cancer service access for Indigenous peoples relative to non-Indigenous peoples. These documents included data from Aotearoa New Zealand, Australia, Canada, and the USA (including Hawai'i). RESULTS: Our review found evidence of disparities in access to, and the journey through, lung cancer care for Indigenous peoples. Disparities were most obvious in access to early detection and surgery, with inconsistent evidence regarding other components of the pathway. CONCLUSION: These observations are made amid relatively scant data in a global sense, highlighting the need for improved data collection and monitoring of cancer care and outcomes for Indigenous peoples worldwide. Access to early detection and guideline-concordant treatment are essential to addressing enduring disparities in cancer survival experienced by Indigenous peoples globally.

RESUMEN

BACKGROUND: Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumours of the gastrointestinal tract. The New Zealand (NZ) population incidence has not previously been documented nor has the potential effect of ethnicity been reviewed. We furthermore wanted to assess the difference between those undergoing a wedge resection versus a more extensive operation which we hypothesised would correlate with recurrence and mortality. METHODS: All patients (n = 103) with a GIST diagnosed and treated at Te Whatu Ora Waitemata (Auckland, New Zealand) between 2012 and 2021 are presented. Patient demographics, method of GIST detection, management approach, index surgery, histological features, use of adjuvant and neoadjuvant imatinib, follow-up, recurrence and mortality rates were analysed. RESULTS: This paper reports the largest NZ GIST cohort to date and estimates an incidence of 17 cases per million per year. Eighty-four patients underwent surgical resection, 58 received a wedge resection and 17 received a more extensive operation. Five-year disease-free survival rates were 100% in the low/very low risk, 90% in the intermediate and 59% in the high risk groups as determined by the modified NIH criteria. Our overall 5-year GIST-specific survival rate was 83%; it was 91% in those who underwent a wedge resection and 60% in the extensive operation group. There is evidence that Maori have higher rates of GIST recurrence compared to non-Maori and are more likely to require an extensive surgical resection.

RESUMEN

BACKGROUND: The clinico-oncological outcomes of precursor epithelial subtypes of adenocarcinoma arising from intraductal papillary mucinous neoplasms (A-IPMN) are limited to small cohort studies. Differences in recurrence patterns and response to adjuvant chemotherapy between A-IPMN subtypes are unknown. METHODS: Clincopathological features, recurrence patterns and long-term outcomes of patients undergoing pancreatic resection (2010-2020) for A-IPMN were reported from 18 academic pancreatic centres worldwide. Precursor epithelial subtype groups were compared using uni- and multivariate analysis. RESULTS: In total, 297 patients were included (median age, 70 years; male, 78.9%), including 54 (18.2%) gastric, 111 (37.3%) pancreatobiliary, 80 (26.9%) intestinal and 52 (17.5%) mixed subtypes. Gastric, pancreaticobiliary and mixed subtypes had comparable clinicopathological features, yet the outcomes were significantly less favourable than the intestinal subtype. The median time to recurrence in gastric, pancreatobiliary, intestinal and mixed subtypes were 32, 30, 61 and 33 months. Gastric and pancreatobiliary subtypes had worse overall recurrence (p = 0.048 and p = 0.049, respectively) compared with the intestinal subtype but gastric and pancreatobiliary subtypes had comparable outcomes. Adjuvant chemotherapy was associated with improved survival in the pancreatobiliary subtype (p = 0.049) but not gastric (p = 0.992), intestinal (p = 0.852) or mixed subtypes (p = 0.723). In multivariate survival analysis, adjuvant chemotherapy was associated with a lower likelihood of death in pancreatobiliary subtype, albeit with borderline significance [hazard ratio (HR) 0.56; 95% confidence interval (CI) 0.31-1.01; p = 0.058]. CONCLUSIONS: Gastric, pancreatobiliary and mixed subtypes have comparable recurrence and survival outcomes, which are inferior to the more indolent intestinal subtype. Pancreatobiliary subtype may respond to adjuvant chemotherapy and further research is warranted to determine the most appropriate adjuvant chemotherapy regimens for each subtype.

RESUMEN

AIM: The primary aim of the study is to define the post-colonoscopy colorectal cancer (PCCRC) three-year rate and the post-endoscopy upper gastrointestinal cancer (PEUGIC) three-year rate across public hospitals in Aotearoa New Zealand. METHOD: This retrospective cohort study will be conducted via the trainee-led STRATA Collaborative network. All public hospitals in Aotearoa New Zealand will be eligible to participate. Data will be collected on all adult patients who are diagnosed with colorectal adenocarcinoma within 6 to 48 months of a colonoscopy and all adult patients diagnosed with gastroesophageal cancer within 6 to 48 months of an upper gastrointestinal endoscopy. The study period will be from 2010 to 2022. The primary outcome is the PCCRC 3-year rate and the PEUGIC 3-year rate. Secondary aims are to define and characterize survival after PCCRC or PEUGIC, the cause of PCCRC as based on the World Endoscopy Organization System of Analysis definitions, trends over time, and centre level variation. CONCLUSION: This protocol describes the methodology for a nationwide retrospective cohort study on PCCRC and PEUGIC in Aotearoa New Zealand. These data will lay the foundation for future studies and quality improvement initiatives.

RESUMEN

BACKGROUND: Intraductal oncocytic papillary neoplasms (IOPNs) of the pancreas are now considered a separate entity to intraductal papillary mucinous neoplasms (IPMN). Invasive IOPNs are extremely rare, and their recurrence patterns, response to adjuvant chemotherapy and long-term survival outcomes are unknown. METHODS: Consecutive patients undergoing pancreatic resection (2010-2020) for invasive IOPNs or adenocarcinoma arising from IPMN (A-IPMN) from 18 academic pancreatic centers worldwide were included. Outcomes of invasive IOPNs were compared with A-IPMN invasive subtypes (ductal and colloid A-IPMN). RESULTS: 415 patients were included: 20 invasive IOPN, 331 ductal A-IPMN and 64 colloid A-IPMN. After a median follow-up of 6-years, 45% and 60% of invasive IOPNs had developed recurrence and died, respectively. There was no significant difference in recurrence or overall survival between invasive IOPN and ductal A-IPMN. Overall survival of invasive IOPNs was inferior to colloid A-IPMNs (median time of survival 24.4 months vs. 86.7, months, p = 0.013), but the difference in recurrence only showed borderline significance (median time to recurrence, 22.5 months vs. 78.5 months, p = 0.132). Adjuvant chemotherapy, after accounting for high-risk features, did not reduce rates of recurrence in invasive IOPN (p = 0.443), ductal carcinoma (p = 0.192) or colloid carcinoma (p = 0.574). CONCLUSIONS: Invasive IOPNs should be considered an aggressive cancer with a recurrence rate and prognosis consistent with ductal type A-IPMN.

RESUMEN

BACKGROUND: Quality performance indicators for the management of oesophagogastric cancer can be used to objectively measure and compare the performance of individual units and capture key elements of patient care to improve patient outcomes. METHODS: Two systematic reviews were completed to identify evidence-based quality performance indicators for the surgical management of oesophagogastric cancer. Based on the indicators identified, a two-round modified Delphi process with invitations was sent to all members of the Australia and Aotearoa New Zealand Gastric and Oesophageal Surgery Association. The expert working group discussed each suggested indicator and either removed, added, or adjusted the list of indicators of oesophagogastric cancer. RESULTS: The final list of both OG cancer indicators included Specialized Multi-disciplinary team discussion, Endoscopy documentation, Staging Contrast CT Chest/Abdomen and Pelvis, Neoadjuvant or Adjuvant chemo/radiotherapy administered in accordance with the Local multi-disciplinary team, Pathological margin clearance (R0 Resection), Lymphadenectomy retrieving 15 or more nodes, Formal review of pathological findings and documentation, Postoperative complications, 30-day and 90-day postoperative mortality, clinical surveillance and Specialized Dietetic guidance. Indicators specific to gastric cancer included Preoperative biopsy for pathological diagnosis and Staging Laparoscopy. Indicators specific to oesophageal cancer include positron emission tomography scan if CT negative for metastasis, Perioperative Oesophagectomy Care Pathway, length of stay of 21 days or more, and Unplanned readmission within 30 days. CONCLUSIONS: The results of this study present a core set of indicators for the surgical management of oesophagogastric cancer that can be used to measure quality and compare performance between different units.

RESUMEN

BACKGROUND: Predictors of long-term survival after resection of adenocarcinoma arising from intraductal papillary mucinous neoplasms are unknown. This study determines predictors of long-term (>5 years) disease-free survival and recurrence in adenocarcinoma arising from intraductal papillary mucinous neoplasms and derives a prognostic model for disease-free survival. METHODS: Consecutive patients who underwent pancreatic resection for adenocarcinoma arising from intraductal papillary mucinous neoplasms in 18 academic pancreatic centers in Europe and Asia between 2010 to 2017 with at least 5-year follow-up were identified. Factors associated with disease-free survival were determined using Cox proportional hazards model. Internal validation was performed, and discrimination and calibration indices were assessed. RESULTS: In the study, 288 patients (median age, 70 years; 52% male) were identified; 140 (48%) patients developed recurrence after a median follow-up of 98 months (interquartile range, 78.4-123), 57 patients (19.8%) developed locoregional recurrence, and 109 patients (37.8%) systemic recurrence. At 5 years after resection, the overall and disease-free survival was 46.5% (134/288) and 35.0% (101/288), respectively. On Cox proportional hazards model analysis, multivisceral resection (hazard ratio, 2.20; 95% confidence interval, 1.06-4.60), pancreatic tail location (hazard ratio, 2.34; 95% confidence interval, 1.22-4.50), poor tumor differentiation (hazard ratio, 2.48; 95% confidence interval, 1.10-5.30), lymphovascular invasion (hazard ratio, 1.74; 95% confidence interval, 1.06-2.88), and perineural invasion (hazard ratio, 1.83; 95% confidence interval, 1.09-3.10) were negatively associated with long-term disease-free survival. The final predictive model incorporated 8 predictors and demonstrated good predictive ability for disease-free survival (C-index, 0.74; calibration, slope 1.00). CONCLUSION: A third of patients achieve long-term disease-free survival (>5 years) after pancreatic resection for adenocarcinoma arising from intraductal papillary mucinous neoplasms. The predictive model developed in the current study can be used to estimate the probability of long-term disease-free survival.

RESUMEN

AIM: This feasibility study was undertaken to implement and assess a Rongoa Maori (traditional Maori healing)/Western medicine collaboration model in a general surgical outpatient setting. METHODS: Six patients were recruited and consulted with both a Rongoa Maori practitioner and a Western trained surgeon three times in 6 months. Appointments were an average of 45 minutes duration, patient whanau (family) were welcome and kai (food) was provided as a culturally appropriate custom. Qualitative interviews were conducted with patients, whanau and practitioners after the final appointment with practitioners. The data were thematically analysed and reviewed by the team researchers. RESULTS: Seven themes were identified from the successful collaboration: benefits of Rongoa/medical collaboration to participants; the high value of healer/doctor relationships with participants; participants' experiences of healer/doctor collaboration; healer/doctor perceptions of the Rongoa/medical collaboration process; paying attention to the ecosystem of each participant; unanimous support for Rongoa/medical collaboration to be implemented in the health system; suggestions for Rongoa/medical collaboration improvement. CONCLUSIONS: Many challenges remain, but collaboration between Rongoa Maori healing and Western health professionals in public hospitals is not only possible, but also meets the need for patient-centred care.

RESUMEN

BACKGROUND: The clinical impact of adjuvant chemotherapy after resection for adenocarcinoma arising from intraductal papillary mucinous neoplasia is unclear. The aim of this study was to identify factors related to receipt of adjuvant chemotherapy and its impact on recurrence and survival. METHODS: This was a multicentre retrospective study of patients undergoing pancreatic resection for adenocarcinoma arising from intraductal papillary mucinous neoplasia between January 2010 and December 2020 at 18 centres. Recurrence and survival outcomes for patients who did and did not receive adjuvant chemotherapy were compared using propensity score matching. RESULTS: Of 459 patients who underwent pancreatic resection, 275 (59.9%) received adjuvant chemotherapy (gemcitabine 51.3%, gemcitabine-capecitabine 21.8%, FOLFIRINOX 8.0%, other 18.9%). Median follow-up was 78 months. The overall recurrence rate was 45.5% and the median time to recurrence was 33 months. In univariable analysis in the matched cohort, adjuvant chemotherapy was not associated with reduced overall (P = 0.713), locoregional (P = 0.283) or systemic (P = 0.592) recurrence, disease-free survival (P = 0.284) or overall survival (P = 0.455). Adjuvant chemotherapy was not associated with reduced site-specific recurrence. In multivariable analysis, there was no association between adjuvant chemotherapy and overall recurrence (HR 0.89, 95% c.i. 0.57 to 1.40), disease-free survival (HR 0.86, 0.59 to 1.30) or overall survival (HR 0.77, 0.50 to 1.20). Adjuvant chemotherapy was not associated with reduced recurrence in any high-risk subgroup (for example, lymph node-positive, higher AJCC stage, poor differentiation). No particular chemotherapy regimen resulted in superior outcomes. CONCLUSION: Chemotherapy following resection of adenocarcinoma arising from intraductal papillary mucinous neoplasia does not appear to influence recurrence rates, recurrence patterns or survival.

RESUMEN

INTRODUCTION: New Zealand has a population of only 5.5 million meaning that for many surgical procedures the country qualifies as a "low-volume center." However, the health system is well developed and required to provide complex surgical procedures that benchmark internationally against comparable countries. This investigation was undertaken to review regional variation and volumes of complex resection and palliative upper gastrointestinal (UGI) surgical procedures within New Zealand. METHODS: Data pertaining to patients undergoing complex resectional UGI procedures (esophagectomy, gastrectomy, pancreatectomy, and hepatectomies) and palliative UGI procedures (esophageal stenting, enteroenterostomy, biliary enteric anastomosis, and liver ablation) in a New Zealand hospital between January 1, 2000 and December 31, 2019 were obtained from the National Minimum Dataset. RESULTS: New Zealand is a low-volume center for UGI surgery (229 hepatectomies, 250 gastrectomies, 126 pancreatectomies, and 74 esophagectomies annually). Over 80% of patients undergoing hepatic resection/ablation, gastrectomy, esophagectomy, and pancreatectomy are treated in one of the six national cancer centers (Auckland, Waikato, Mid-Central, Capital Coast, Canterbury, or Southern). There is evidence of the decreasing frequency of these procedures in small centers with increasing frequency in large centers suggesting that some regionalization is occurring. Palliative procedures were more widely performed. Indigenous Maori were less likely to be treated in a nationally designated cancer center than non-Maori. CONCLUSIONS: The challenge for New Zealand and similarly sized countries is to develop and implement a system that optimizes the skills and pathways that come from a frequent performance of complex surgery while maintaining system resilience and ensuring equitable access for all patients.

RESUMEN

BACKGROUND: Videos on Robotic pancreaticoduodenectomy (RPD) may be watched by surgeons learning RPD. This study sought to appraise the educational quality of RPD videos on YouTube. METHODS: One-hundred videos showing RPD or 'Robotic Whipple' were assessed using validated scales (LAP-VEGaS & Consensus Statement Score (CSS)). The association between the scores and the video characteristics (e.g. order of appearance, provider type etc) was assessed. The minimum number of videos required to cumulatively cover the entire LAP-VEGaS and CSS was also noted. RESULTS: The videos were of variable quality; median LAP-VEGaS = 0.67 (0.17-0.94), median CSS = 0.45 (0.29-0.53). There was no association between the educational quality of the videos and their order of appearance, view counts, provider type, length or country of origin. Videos lacked information such as patient consent (100%), potential pitfalls (97%) or surgeon credentials (84%). The first 29 videos cumulatively met all the criteria of CSS and LAP-VEGaS scores except for reporting consent. CONCLUSION: YouTube videos on RPD are of variable quality, without any recognised predictors of quality, and miss important safety information. An impractical number of videos need to be watched to cumulatively fulfil educational criteria. There is a need for high-quality, peer-reviewed videos that adhere to educational principles.

RESUMEN

BACKGROUND: An increasing number of older patients are undergoing emergency laparotomy (EL). Frailty is thought to contribute to adverse outcomes in this group. The best method to assess frailty and impacts on long-term mortality and other important functional outcomes for older EL patients have not been fully explored. METHODS: A prospective multicenter study of older EL patients was conducted across four hospital sites in New Zealand from August 2017 to September 2022. The Clinical Frailty Scale (CFS) was used to measure frailty-defined as a CFS of ≥5. Primary outcomes were 30-day and one-year mortality. Secondary outcomes were postoperative morbidity, admission for rehabilitation, and increased care level on discharge. A multivariate logistic regression analysis was conducted, adjusting for age, sex, and ethnicity. RESULTS: A total of 629 participants were included. Frailty prevalence was 14.6%. Frail participants demonstrated higher 30-day and 1-year mortality-20.7% and 39.1%. Following adjustment, frailty was directly associated with a significantly increased risk of short- and long-term mortality (30-day aRR 2.6, 95% CI 1.5, 4.3, p = <0.001, 1-year aRR 2.0, 95% CI 1.5, 2.8, p < 0.001). Frailty was correlated with a 2-fold increased risk of admission for rehabilitation and propensity of being discharged to an increased level of care, complications, and readmission within 30 days. CONCLUSION: Frailty was associated with increased risk of postoperative mortality up to 1-year and other functional outcomes for older patients undergoing EL. Identification of frailty in older EL patients aids in patient-centered decision-making, which may lead to improvement in outcomes.

RESUMEN

OBJECTIVES: The objective of this study is to investigate the influence of diabetes on breast cancer-specific survival among women with breast cancer in Aotearoa/New Zealand. METHODS: This study included women diagnosed with invasive breast cancer between 2005 and 2020, with their information documented in the Te Rehita Mate Utaetae-Breast Cancer Foundation National Register. Breast cancer survival curves for women with diabetes and those without diabetes were generated using the Kaplan-Meier method. The hazard ratio (HR) of breast cancer-specific mortality for women with diabetes compared to women without diabetes was estimated using the Cox proportional hazards model. RESULTS: For women with diabetes, the 5-year and 10-year of cancer-specific survival were 87% (95% CI: 85%-88%) and 79% (95% CI: 76%-81%) compared to 89% (95% CI: 89%-90%) and 84% (95% CI: 83%-85%) for women without diabetes. The HR of cancer-specific mortality for patients with diabetes compared to those without diabetes was 0.99 (95% CI: 0.89-1.11) after adjustment for patient demographics, tumor characteristics, and treatments. Age at cancer diagnosis and cancer stage had the biggest impact on the survival difference between the two groups. When stratified by cancer stage, the cancer-specific mortality between the two groups was similar. CONCLUSIONS: While differences in survival have been identified for women with diabetes when compared to women without diabetes, these are attributable to age and the finding that women with diabetes tend to present with more advanced disease at diagnosis. We did not find any difference in survival between the two groups due to differences in treatment.

OBJECTIVE: The aim of the present study was to compare long-term post-resection oncological outcomes between A-IPMN and PDAC. SUMMARY BACKGROUND DATA: Knowledge of long term oncological outcomes (e.g recurrence and survival data) comparing between adenocarcinoma arising from intraductal papillary mucinous neoplasms (A-IPMN) and pancreatic ductal adenocarcinoma (PDAC) is scarce. METHODS: Patients undergoing pancreatic resection (2010-2020) for A-IPMN were identified retrospectively from 18 academic pancreatic centres and compared with PDAC patients from the same time-period. Propensity-score matching (PSM) was performed and survival and recurrence were compared between A-IPMN and PDAC. RESULTS: 459 A-IPMN patients (median age,70; M:F,250:209) were compared with 476 PDAC patients (median age,69; M:F,262:214). A-IPMN patients had lower T-stage, lymphovascular invasion (51.4%vs. 75.6%), perineural invasion (55.8%vs. 71.2%), lymph node positivity (47.3vs. 72.3%) and R1 resection (38.6%vs. 56.3%) compared to PDAC(P<0.001). The median survival and time-to-recurrence for A-IPMN versus PDAC were 39.0 versus19.5months (P<0.001) and 33.1 versus 14.8months (P<0.001), respectively (median follow-up,78 vs.73 months). Ten-year overall survival for A-IPMN was 34.6%(27/78) and PDAC was 9%(6/67). A-IPMN had higher rates of peritoneal (23.0 vs. 9.1%, P<0.001) and lung recurrence (27.8% vs. 15.6%, P<0.001) but lower rates of locoregional recurrence (39.7% vs. 57.8%; P<0.001). Matched analysis demonstrated inferior overall survival (P=0.005), inferior disease-free survival (P=0.003) and higher locoregional recurrence (P<0.001) in PDAC compared to A-IPMN but no significant difference in systemic recurrence rates (P=0.695). CONCLUSIONS: PDACs have inferior survival and higher recurrence rates compared to A-IPMN in matched cohorts. Locoregional recurrence is higher in PDAC but systemic recurrence rates are comparable and constituted by their own distinctive site-specific recurrence patterns.

RESUMEN

BACKGROUND: The majority of patients with pancreatic adenocarcinoma (PDAC) have advanced disease at presentation, preventing treatment with curative intent. Management of these patients is often provided by surgical teams for whom there are a lack of widely accepted strategies for care. The aim of this study was to conduct a systematic review to identify key issues in patients with advanced PDAC and integrate the evidence to form a care bundle checklist for use in surgical clinics. METHODS: A systematic review of the literature was performed regarding best supportive care for advanced PDAC according to the PRISMA guidelines. Interventions pertaining to supportive care were included whilst preventative and curative treatments were excluded. A narrative review was planned. RESULTS: Forty-four studies were assessed and four themes were developed: (i) Pain is an undertreated symptom, requiring escalating analgesics and sometimes invasive modalities. (ii) Health-related quality of life necessitates optimisation by involving family, carers and multi-disciplinary teams. (iii) Malnutrition and weight loss can be mitigated with early assessment, replacement therapies and resistance exercise. (iv) Biliary and duodenal obstruction can often be relieved by endoscopic/radiological interventions with surgery rarely required. CONCLUSION: This is the first systematic review to evaluate the different types of interventions utilized during best supportive care in patients with advanced PDAC. It provides a comprehensive care bundle for surgeons that informs management of the common issues experienced by patients within a multidisciplinary environment.

RESUMEN

PURPOSE: Indigenous communities experience worse cancer outcomes compared with the general population partly because of lower cancer screening access. One-size-fits-all screening programs are unsuitable for reaching Indigenous communities. In this review, we summarize available evidence on the perspectives of these communities; with a view to informing the improvement of cancer screening services to achieve equitable access. METHODS: We undertook a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, using the databases MEDLINE, Scopus, PubMed, and Google Scholar. The search terms used were "Indigenous community or Indigenous communities," "cancer screening," and "facilitators, enablers, desires, or needs." Qualitative studies published up to the August 30, 2022 investigating the perspectives of Indigenous communities on factors encouraging screening participation were included in the study. The included studies were reviewed and analyzed inductively by two independent reviewers, and key themes regarding indigenous access to cancer screening were then extracted. RESULTS: A total of 204 unique articles were identified from the search. The title and abstracts of these studies were screened, and 164 were excluded on the basis of the exclusion and inclusion criteria. The full texts of the remaining 40 studies were examined and 18 were included in the review. Four key themes were identified pertaining to culturally tailored education and information dissemination, community involvement, positive relationships with health care providers, and individual empowerment and autonomy. CONCLUSION: Improvements, on the basis of the key themes identified from this review, must be made at all levels of the health care system to achieve equitable screening participation in Indigenous communities. However, we recommend an investigation into the perspectives of the local Indigenous communities before the initiation of cancer screening programs.

RESUMEN

PURPOSE: Lung cancer is the biggest cancer killer of indigenous peoples worldwide, including Maori people in New Zealand. There is some evidence of disparities in access to lung cancer treatment between Maori and non-Maori patients, but an examination of the depth and breadth of these disparities is needed. Here, we use national-level data to examine disparities in access to surgery, radiation therapy and systemic therapy between Maori and European patients, as well as timing of treatment relative to diagnosis. METHODS: We included all lung cancer registrations across New Zealand from 2007 to 2019 (N = 27,869) and compared access with treatment and the timing of treatment using national-level inpatient, outpatient, and pharmaceutical records. RESULTS: Maori patients with lung cancer appeared less likely to access surgery than European patients (Maori, 14%; European, 20%; adjusted odds ratio [adj OR], 0.82 [95% CI, 0.73 to 0.92]), including curative surgery (Maori, 10%; European, 16%; adj OR, 0.72 [95% CI, 0.62 to 0.84]). These differences were only partially explained by stage and comorbidity. There were no differences in access to radiation therapy or systemic therapy once adjusted for confounding by age. Although it appeared that there was a longer time from diagnosis to radiation therapy for Maori patients compared with European patients, this difference was small and requires further investigation. CONCLUSION: Our observation of differences in surgery rates between Maori and European patients with lung cancer who were not explained by stage of disease, tumor type, or comorbidity suggests that Maori patients who may be good candidates for surgery are missing out on this treatment to a greater extent than their European counterparts.
