Room to Improve: An Audit of In-Hospital End-of-Life Care for Oncology Patients in a Tertiary Cancer Centre in Ireland During the COVID-19 Pandemic.

The COVID-19 pandemic compounded isolation for patients through social distancing measures and staff shortages. We were concerned about the impact of COVID-19 on the quality of care provided at end-of-life in 2021 in a national cancer centre, and instigated the first ever review of the care of the dying. Quality of care was assessed retrospectively using a validated instrument developed by the United Kingdom's National Quality Board. Sixty-six patient deaths occurred in our cancer centre in 2021. The 'risk of dying' was documented in 65.2% of records. Palliative care services were involved in 77%, and pastoral care in 10.6%. What was important to the patient was documented in 24.2%. The 'quality-of-death' score was satisfactory for most but poor in 21.2%. Our study prompted change, including appointment of an end-of-life coordinator, development of a checklist to ensure comprehensive communication, expansion of the end-of-life committee to include junior doctors, and regular audit.

A pilot project investigating the use of ONCOpatient®-An electronic patient-reported outcomes app for oncology patients.

Purpose: To investigate the feasibility of implementing a remote patient monitoring system using an electronic patient-reported outcomes (ePROs) platform in a tertiary cancer center in the Republic of Ireland. Methods: Patients receiving oral chemotherapy and oncology clinicians were invited to participate in the study. Patients were asked to submit weekly symptom questionnaires through an ePRO mobile phone application (app)-ONCOpatient®. Clinical staff were invited to use the ONCOpatient® clinician interface. After 8 weeks all participants submitted evaluation questionnaires. Results: Thirteen patients and five staff were enrolled in the study. The majority of patients were female (85%) with a median age of 48 years (range 22-73). Most (92%) were enrolled over telephone requiring on average 16 minutes. Compliance with the weekly assessments was 91%. Alerts were triggered by 40% of patients who then required phone calls to aid with symptom management. At the end of study, 87% of patients reported they would use the app frequently, 75% reported that the platform met their expectations, and 25% that it exceeded their expectations. Similarly, 100% of staff reported they would use the app frequently, 60% reported that it met their expectations, and 40% that it exceeded their expectations. Conclusions: Our pilot study showed that it is feasible to implement ePRO platforms in the Irish clinical setting. Small sample bias was recognized as a limitation, and we plan to confirm our findings on a larger cohort of patients. In the next phase we will integrate wearables including remote blood pressure monitoring.

Are CT-Derived Muscle Measurements Prognostic, Independent of Systemic Inflammation, in Good Performance Status Patients with Advanced Cancer?

The present study examined the relationships between CT-derived muscle measurements, systemic inflammation, and survival in advanced cancer patients with good performance status (ECOG-PS 0/1). Data was collected prospectively from patients with advanced cancer undergoing anti-cancer therapy with palliative intent. The CT Sarcopenia score (CT-SS) was calculated by combining the CT-derived skeletal muscle index (SMI) and density (SMD). The systemic inflammatory status was determined using the modified Glasgow Prognostic Score (mGPS). The primary outcome of interest was overall survival (OS). Univariate and multivariate Cox regressions were used for survival analysis. Three hundred and seven patients met the inclusion criteria, out of which 62% (n = 109) were male and 47% (n = 144) were ≥65 years of age, while 38% (n = 118) were CT-SS ≥ 1 and 47% (n = 112) of patients with pre-study blood were inflamed (mGPS ≥ 1). The median survival from entry to the study was 11.1 months (1-68.1). On univariate analysis, cancer type (p < 0.05) and mGPS (p < 0.001) were significantly associated with OS. On multivariate analysis, only mGPS (p < 0.001) remained significantly associated with OS. In patients who were ECOG-PS 0, mGPS was significantly associated with CT-SS (p < 0.05). mGPS may dominate the prognostic value of CT-derived sarcopenia in good-performance-status patients with advanced cancer.

Real-world outcomes and toxicity of adjuvant chemotherapy in NSCLC: a single-center experience.

Aim: Adjuvant chemotherapy in NSCLC is associated with modest benefits and significant toxicity. We sought to evaluate the toxicity of adjuvant chemotherapy and disease-specific outcomes in a real-world population. Methods: We performed a retrospective analysis of patients undergoing adjuvant chemotherapy for NSCLC in an Irish center over a 7-year period. We described treatment-associated toxicity, recurrence-free survival and overall survival. Results: 62 patients underwent adjuvant chemotherapy. Treatment-associated hospitalisation occurred in 29% of patients. Relapse was recorded in 56% of patients and median recurrence-free survival was 27 months. Conclusion: High rates of disease recurrence and treatment-associated morbidity were observed in patients receiving adjuvant chemotherapy for NSCLC. Novel therapeutic strategies are required to improve outcomes in this population.

Early NSCLC is primarily managed with lung cancer surgery. Chemotherapy is offered to some patients with early NSCLC after surgery depending on the size of the tumor and lymph node involvement. The benefit of post-surgery (adjuvant) chemotherapy in reducing the chance of cancer recurrence has been shown to be relatively small in previous studies. Large studies of post-surgery chemotherapy in NSCLC have included limited numbers of older patients, and patients with significant medical issues. This study looked to evaluate the safety and treatment-associated side effects of adjuvant chemotherapy in a group of patients more reflective of everyday clinical practice, and to assess the rates of cancer recurrence in these patients. In our study of 62 patients who underwent adjuvant chemotherapy for NSCLC, nearly 1 in 3 patients required hospital admission due to treatment-associated side effects. Almost 40% of patients experienced significant blood test abnormalities (including anaemia, reduced platelets, and reduced white blood cells). Approximately 1 in 4 patients required a reduction in the doses of their treatment due to treatment-associated side effects. More than half of the patients in our study experienced a recurrence of their cancer. Our study demonstrates the significant side effects associated with adjuvant chemotherapy in NSCLC and highlights the need for better-tolerated treatment strategies to reduce cancer recurrence in early NSCLC.

Lactate dehydrogenase: relationship with the diagnostic GLIM criterion for cachexia in patients with advanced cancer.

BACKGROUND: Although suggestive of dysregulated metabolism, the relationship between serum LDH level, phenotypic/aetiologic diagnostic Global Leadership Initiative on Malnutrition (GLIM) criteria and survival in patients with advanced cancer has yet to examined. METHODS: Prospectively collected data from patients with advanced cancer, undergoing anti-cancer therapy with palliative intent, across nine sites in the UK and Ireland between 2011-2016, was retrospectively analysed. LDH values were grouped as <250/250-500/>500 Units/L. Relationships were examined using χ2 test for linear-by-linear association and binary logistics regression analysis. RESULTS: A total of 436 patients met the inclusion criteria. 46% (n = 200) were male and 59% (n = 259) were ≥65 years of age. The median serum LDH was 394 Units/L and 33.5% (n = 146) had an LDH > 500 Units/L. LDH was significantly associated with ECOG-PS (p < 0.001), NLR (p < 0.05), mGPS (p < 0.05) and 3-month survival (p < 0.001). LDH was significantly associated with 3-month survival independent of weight loss (p < 0.01), BMI (p < 0.05), skeletal muscle mass (p < 0.01), metastatic disease (p < 0.05), NLR (p < 0.05) and mGPS (p < 0.01). DISCUSSION: LDH was associated with performance status, systemic inflammation and survival in patients with advanced cancer. LDH measurement may be considered as an aetiologic criteria and become a potential therapeutic target in the treatment of cancer cachexia.

Consensus statement on the surveillance of patients with gastrointestinal malignancies.

BACKGROUND: Improvements in early detection, screening and treatment of cancer have resulted in a significant improvement in cancer mortality and an increase in the number of cancer survivors globally. Accordingly, a significant rise in the number of cancer survivors in Ireland has been observed. The surveillance of survivors of gastrointestinal malignancies in Ireland is heterogeneous and represents an unmet need for standardisation. AIMS: There are currently no national guidelines in Ireland to guide follow-up practices for these patients. The aim of this study was to establish homogeneity nationally with respect to follow-up of these patients by medical oncologists. METHODS/RESULTS: A consensus group consisting of Irish oncologists with an interest in gastrointestinal malignancies was created to address this issue, and determined that it would be reasonable to adopt the NCCN guidelines for this purpose, but that this recommendation would not be prescriptive, and should be individualised to each patient. CONCLUSION: We hope that this initiative may help to homogenise survivorship practices in this cohort of Irish patients, and may support the implementation of survivorship initiatives by the National Cancer Control Programme (NCCP).

Cost and public reimbursement of cancer medicines in the UK and the Republic of Ireland.

INTRODUCTION/AIMS: There are disparities in the availability of systemic anticancer therapies (SACTs) globally. We set out to investigate the cost and reimbursement of SACTs in the United Kingdom (UK) and the Republic of Ireland (ROI) in conjunction with efficacy and licensing authority decisions in the United States (US) and the European Union (EU). METHODS: We sought data pertaining to licensing in the EU, reimbursement in ROI/UK and cost/efficacy of SACTs licensed by the Food and Drug Administration (FDA) between January 2015 and May 2021. Independent samples t tests, chi-square test and Pearson's correlation were used for statistical analysis. RESULTS: We identified that the majority of FDA-approved regimens are licensed by the European Medicines Agency (EMA) (n = 91, 67.9%). However, only a minority of these are currently reimbursed in the UK (n = 60, 45%) or the ROI (n = 28, 21%) as of the 1st of May 2021. In addition, only a minority of regimens have demonstrated a statistically significant OS benefit (n = 54, 40%). There was no association between cost of regimens and either the presence (t = 0.846, p = 0.40) or duration of OS benefit (t = - 0.84, p = 0.64). CONCLUSIONS: Our study highlights that many licensed systemic anticancer treatments are not currently reimbursed in ROI/UK. The high cost of these medicines is independent of the presence of an OS benefit. Collaboration between regulatory agencies, governments and industry partners is needed to ensure health expenditure is directed towards the most effective treatments.

A large, multi-centre prospective study demonstrating high prevalence of malnutrition associated with reduced survival in ambulatory systemic anti-cancer therapy patients.

BACKGROUND & AIMS: The nutritional status of cancer patients is highly variable, and known to impact on clinical outcomes. To date, no large study evaluating the nutritional status of Irish cancer patients has been reported. The aim of this study was to describe the nutritional status, using gold standard methods, of a large cohort of ambulatory oncology patients receiving Systemic Anti-Cancer Therapy and to assess the impact of abnormal body composition phenotypes on survival. METHODS: A prospective study in adults undergoing Systemic Anti-Cancer Therapy for solid tumours enrolled patients between 2012 and 2016. Baseline details were collected incorporating demographics, cancer pathology, lifestyle, body composition (by computed tomography (CT), and inflammatory status. Skeletal muscle index (SMI) and mean muscle attenuation (MA) were obtained from CT images and categorised to low muscle mass and low MA using previously published sex specific cut points. Survival was monitored for a median of 25 months [IQR:10-46 months]. Survival analyses were conducted using multivariate Cox Proportional Hazards Models. RESULTS: Of 1015 patients recruited, 940 patients with an evaluable CT were included in this analysis. Median age was 64 years [IQR 55-71] and 56% were male. Colorectal cancer (28%) and gastro-oesophageal (16%) were the most common diagnoses and 58% of patients had stage IV disease. Despite 56% being overweight or obese (BMI >25 kg/m2), 52% were weight losing and 17% had lost >10% body weight. Cancer Cachexia (CC) was present in 42%, 39% had low muscle mass (MM) (sarcopenia) and 45% had low MA. Overall, 73% of patients exhibited an abnormal body composition (BC) phenotype (≥1 of CC, low MM/MA). Overall survival was significantly lower in those with abnormal BC phenotype, independent of site, stage, sex, ECOG and mGPS (HR: 1.416 [95% CI: 1.069-1.875], p = 0.015). CONCLUSIONS: Malnutrition and abnormal body composition phenotypes are common in cancer, but are often masked by adiposity. Appropriate screening and diagnostic tools should consider this co-presentation of overweight and obesity, alongside muscle depletion. Given that abnormal body composition phenotypes detectable only via CT are associated with reduced survival, these should be more widely employed to identify patients at risk of poor prognosis, and allow potentially more effective, early intervention.

Pembrolizumab-associated erythema nodosum in the treatment of metastatic melanoma.

A 66-year-old woman receiving pembrolizumab for metastatic melanoma presented with tender red nodules on her shins and forearms. Biopsy was consistent with erythema nodosum (EN). The eruption responded to oral minocycline and potent topical steroids. Subsequent investigations detected bihilar lymphadenopathy, biopsied as granulomatous lymphadenitis, confirming the diagnosis of pembrolizumab-associated sarcoidosis. Pembrolizumab was stopped for two cycles and was restarted without recrudescence of EN or bihilar lymphadenopathy. Immunotherapy-associated sarcoidosis is a rare but recognized adverse event related to therapy with immune checkpoint inhibitors. EN is an uncommon manifestation of immunotherapy-induced sarcoidosis. New-onset bihilar lymphadenopathy in the context of immunotherapy requires prompt histological evaluation to differentiate between immunotherapy-associated sarcoidosis and metastatic progression. We review the literature related to immunotherapy-associated EN.

Pembrolizumab (trade name Keytruda^®) is a type of immune therapy that stimulates the body's immune system to fight cancer cells. This immune therapy can cause a variety of rashes. In this article, we describe a patient who developed a red lumpy rash on her limbs that is not commonly described with pembrolizumab. A woman was diagnosed with advanced melanoma and was treated with pembrolizumab. She developed a red lumpy rash on her arms and legs, and a biopsy showed signs of a condition called erythema nodosum. Treatment with an antibiotic tablet and strong steroid ointment were helpful. Scans of her chest showed signs of sarcoidosis in her lungs, which can be associated with erythema nodosum. Pembrolizumab was stopped, and both the rash and lung sarcoidosis stayed away when it was restarted. This type of rash has rarely been described with this kind of immune therapy, and it can be a sign of lung involvement.

Therapeutic Response Evaluation in Advanced Melanoma Patients Incorporating Plasma cfDNA, LDH, VEGF, PD-L1, and IFN-γ Measurements.

BACKGROUND/AIM: Current treatment strategies for advanced melanoma require serial assessment of disease status in affected patients. In this study, we sought to examine the relationship between radiographic tumour burden and blood borne biomarkers including plasma cfDNA, serum LDH, plasma VEGF, PD-L1 and IFN-γ in advanced melanoma patients receiving immunotherapy. We hypothesized that a combination of these explanatory variables in a suitable regression analysis model may predict changes in tumour burden during patient treatment. MATERIALS AND METHODS: We extracted and quantified circulating cfDNA, LDH, VEGF, PD-L1, and IFN-γ from thirty patients with stage IV melanoma at baseline and at six months. All participating patients were evaluated with paired blood sample collection and CT scan assessments during treatment. RESULTS: Changes in radiographic tumour burden correlated with changes in levels of cfDNA (p≤0.001), LDH (p≤0.001), VEGF (p≤0.001), and PD-L1 (p<0.05) during treatment. Multiple regression analysis consisting of the follow-up to baseline assessment ratios of cfDNA, LDH, VEGF and PD-L1 explained changes in tumour burden (F (4, 23)=32.05, p<0.001); with an R2 of 0.8479 (Y=ß0+ß1*B+ß2*C+ß3*D+ß4*E). CONCLUSION: A quantitative measure of cfDNA, LDH, VEGF and PD-L1 may complement current methods of assessing tumour burden in advanced melanoma patients.

The implication of BRAF mutation in advanced colorectal cancer.

BACKGROUND: Advanced colorectal cancer (CRC) is frequently a lethal disease. Mutations in the BRAF gene is a key driver in CRC pathogenesis and confers a poor prognosis. To date, Irish data on this molecular subtype of CRC is lacking. AIMS: Our aim was to compare the natural history of Irish patients with BRAF (BRAFMUT) metastatic CRC with a control group of metastatic CRC patients without BRAF mutation (BRAFWT wild- type). METHOD: A retrospective observational analysis of advanced CRC patients with known BRAFMUT was conducted by chart review. BRAFMUT patients were identified from the Cork University Hospital (CUH) histopathology database. Controls with known BRAFWT were randomly selected from the database. Demographic characteristics and clinicopathological data were recorded. Survival was assessed with Kaplan-Meier curve/Cox proportional hazard models. RESULTS: Twenty patients with BRAFMUT and 36 with BRAFWT were studied. BRAFMUT were more likely female (75% vs 33%, p = 0.007) and right-sided (65% vs 31.4%, p = 0.033). Median overall survival was lower in BRAFMUT group (17.3 months (95% CI 0-40.8)) compared to patients with BRAFWT (median survival not reached, log rank p = 0.001). On multivariate analysis, BRAFMUT was independently associated with an increased risk of mortality (HR 12.76 (95% CI 3.15-51.7), p < 0.001). CONCLUSION: BRAFMUT advanced colorectal cancer was associated with significantly reduced overall survival in this Irish CRC population. Knowledge of mutation status should now be considered standard of care and should dictate management. Surgeons should be aware of this genetic signature as the natural history of the disease may mitigate against an aggressive surgical strategy. A prospective study should be conducted to further corroborate these findings.

Malignant triton tumour (MTT) of the lung with metastasis to the proximal femur.

A 65-year-old female patient has a history of malignant triton tumour of the right upper lobe of the lung. She underwent right upper lobectomy and lymphadenectomy in May 2018. She presented in November 2019 with pathological fracture of the left proximal femur. It was not associated with neurofibromatosis. We decided to do an excisional biopsy of the mass and proximal femoral replacement followed by radiotherapy. Four months later, she presented with local recurrence. We organised a multidisciplinary team between the orthopaedic, histopathology and oncology teams. Then, we decided to treat her with chemotherapy. After 2 months of follow-up, she responded well to the chemotherapy with no further deterioration of her condition.

A national survey of oncology survivors examining nutrition attitudes, problems and behaviours, and access to dietetic care throughout the cancer journey.

BACKGROUND: Attitudes of cancer survivors to nutrition and nutrition care have rarely been captured. A better understanding of their needs based on a review of their experiences would give voice to this patient group (which has rarely been captured) and allow for better planning of nutritional care. AIMS: To conduct a national survey to determine: (1) survivors' experience in relation to nutrition and diet-related problems, (2) perceived importance of the role of nutrition to cancer survivors, (3) the experience of accessing dietetic support, (4) the sources where survivors get nutrition information, and (5) their use of alternative dietary strategies. METHODS: Survivors (any adult ever diagnosed with cancer) who had been diagnosed with or treated for cancer in Ireland within the past 5 years, were asked to complete a 25-item paper-based survey at one of 20 different hospital sites in Ireland. The survey was also hosted online on the websites of major cancer charities. Descriptive statistics were used to examine quantitative data. RESULTS: In total, 1073 valid responses were received (63% female, mean age 57 years (range 18-88)). Breast cancer was the most common (n = 362), followed by colorectal (n = 121). One third of respondents had metastatic disease. Diet-related problems were reported by 45%. Weight loss was experienced by 44% and amongst those, 42% reported they were 'unhappy or worried' by this, while 27% reportedbeing 'delighted/happy' with their weight loss. Muscle loss was noted by 52%, with 20% reporting they had noticed 'a lot' of muscle loss. Nutrition was rated as 'very/extremely' important to cancer care by 89% of respondents, yet 58% reported being asked about dietary issues by their medical team only 'sometimes', 'rarely' or 'never'. Only 39% had been assessed/treated by a registered dietitian (RD) and 74% rated their advice/care as 'very/extremely' helpful. Worryingly, 39% of survivors with involuntary weight loss, and 29% of survivors on a texture modified diet had not received nutritional care from an RD. Overall, 57% of those who did not see an RD said they wanted more dietetic support (access to a helpline/dietitian/additional reliable information). Of concern, 37% of survivors were following or had tried alternative, unproven dietary strategies (e.g. restrictive diets, herbal remedies, juicing or detoxes), and 32% reported avoiding specific foods, e.g. processed meat or dairy. A majority (56%) felt confused by the often conflicting nutrition information available in the media and offered by people around them. CONCLUSIONS: While nutrition is considered highly important by cancer survivors and a high proportion experience potentially serious diet-related problems including weight and muscle loss, fewer than half surveyed had access to a dietitian. Over a third had used at least one alternative dietary strategy, and over half felt confused about nutrition. Comprehensive nutritional screening and referral programmes to oncology dietitians need to be implemented in the ambulatory setting in order to identify and facilitate early management of the nutritional concerns of cancer survivors.

Assessing the Quality of Care Delivered to Transgender and Gender Diverse Patients with Cancer in Ireland: A Case Series.

INTRODUCTION: "Transgender" and "gender diverse" are umbrella terms encompassing those whose gender identities or expressions differ from those typically associated with the sex they were assigned at birth. There is scant global information on cancer incidence, outcome, and mortality for this cohort. This group may present with advanced cancer, have mistrust in health care services and report anxiety and depression at higher frequencies, a finding often seen in marginalized groups because of minority stress. MATERIALS AND METHODS: Medical oncologists were contacted by secure email to identify patients who self-identify as transgender and gender diverse in three Irish hospitals. Five patients were identified. A retrospective chart review was conducted and a pseudonymized patient survey was distributed. RESULTS: All patients included in our chart review (n = 5) were diagnosed with advanced disease on initial diagnosis. Two patients identified as men, two as women, and one as a transwoman. Two of five patients' health record charts reflected a name or gender change. Three patients had gender transitioning treatment postponed. Assessing comorbidities, it was seen that four patients required psychiatry input. Predominant issues noted in our patient survey by the two respondents (n = 2) were "mis-gendering," lack of a gender-neutral hospital environment, lack of inclusion in cancer groups, and barriers in changing name and/or sex on hospital records. CONCLUSION: Components of care requiring revision include patient accessible pathways to change names and gender on health records, earlier access to psychological support and targeted screening and support groups. Resources for hospital staff to improve awareness of correct terminology and to provide gender neutral facilities are worthwhile. IMPLICATIONS FOR PRACTICE: The implications for practice on an international level include patient-friendly pathways for changing hospital name and gender so that patients may feel comfortable using wristbands. The need for international screening guidelines for transgender patients and national transgender cancer support groups is highlighted. On a day-to-day level for providers, the correct use of pronouns makes a big difference to patients. Asking about preferred pronoun on first visit and noting on patient's file is worthwhile. It is important for providers to know that increased psychological support should be offered early on first clinic visit and engaged with as necessary when patient has a history of anxiety or depression. Providers should discuss openly that some gender transitioning treatment will be postponed because of cancer care and refer to both the physical and psychological sequelae of this. Asking transgender patients which room or bathroom they would prefer when rooms are gendered is essential.

The Relationship between ECOG-PS, mGPS, BMI/WL Grade and Body Composition and Physical Function in Patients with Advanced Cancer.

Cancer remains one of the leading causes of mortality worldwide and the associated reduction in physical function has a marked impact on both quality of life and survival. The aim of the present study was to examine the relationship between Eastern Cooperative Oncology Group-Performance status (ECOG-PS), modified Glasgow Prognostic Score (mGPS), Body Mass Index/ Weight Loss grade (BMI/WL grade), and Computerised Tomography (CT)-derived body composition measurement and physical function in patients with advanced cancer. Nine sites contributed prospective data on patient demographics, ECOG-PS, mGPS, physical function tests, and CT-derived body composition. Categorical variables were analysed using χ2 test for linear-by-linear association, or χ2 test for 2-by-2 tables. Associations were analysed using binary logistic regression. A total of 523 cancer patients (266 males, 257 females) were included in the final analysis and most had metastatic disease (83.2%). The median overall survival was 5.6 months. On multivariate binary logistic regression analysis, a high ECOG-PS remained independently associated with a low skeletal muscle index (p < 0.001), low skeletal muscle density (p < 0.05), and timed up and go test failure (p < 0.001). A high mGPS remained independently associated with a low skeletal muscle density (p < 0.05) and hand grip strength test failure (p < 0.01). A high BMI/WL grade remained independently associated with a low subcutaneous fat index (p < 0.05), low visceral obesity (p < 0.01), and low skeletal muscle density (p < 0.05). In conclusion, a high ECOG-PS and a high mGPS as outlined in the ECOG-PS/mGPS framework were consistently associated with poorer body composition and physical function in patients with advanced cancer.

Determinants of quality of life in patients with incurable cancer.

BACKGROUND: Optimizing quality of life (QoL) remains the central tenet of care in patients with incurable cancer; however, determinants of QoL are not clear. The objective of the current study was to examine which factors influence QoL in patients with incurable cancer. METHODS: A multicenter study of adult patients with advanced cancer was conducted in Ireland and the United Kingdom between 2011 and 2016. Data were collected from patients at study entry and included patient demographics, Eastern Cooperative Oncology Group performance status (ECOG-PS), nutritional parameters (the percentage weight loss [%WL]), muscle parameters assessed using computed tomography images (skeletal muscle index and skeletal muscle attenuation), inflammatory markers (modified Glasgow Prognostic score [mGPS]), and QoL data (the European Organization for Research and Treatment Quality-of-Life Questionnaire C-30). The relation between clinical, nutritional, and inflammatory parameters with QoL was assessed using the Spearman rank correlation coefficient and multivariate binary logistic regression. Components of the European Organization for Research and Treatment Quality-of-Life Questionnaire C-30 (physical function, fatigue, and appetite loss) and summary QoL scores were mean-dichotomized for the logistic regression analyses. RESULTS: Data were available for 1027 patients (51% men; median age, 66 years). Gastrointestinal cancer was most prevalent (40%), followed by lung cancer (26%) and breast cancer (9%). Distant metastatic disease was present in 87% of patients. The %WL, ECOG-PS, and mGPS were significantly correlated with deteriorating QoL functional and symptom scales (all P < .001). On multivariate regression analysis, >10% WL (odds ratio [OR], 2.69; 95% CI, 1.63-4.42), an ECOG-PS of 3 or 4 (OR, 14.33; 95% CI, 6.76-30.37), and an mGPS of 2 (OR, 1.58; 95% CI, 1.09-2.29) were independently associated with poorer summary QoL scores. These parameters were also independently associated with poorer physical function, fatigue, and appetite loss (all P < .05). Low skeletal muscle attenuation was independently associated with poorer physical functioning (OR, 1.67; 95% CI, 1.09-2.56), but muscle parameters were not independently associated with fatigue, appetite loss, or QoL summary scores. CONCLUSIONS: The current findings indicate that QoL is determined (at least in part) by WL, ECOG-PS, and the systemic inflammatory response in patients with advanced cancer. Identifying early predictors of poor QoL may allow the identification of patients who may benefit from early referral to palliative and supportive care, which has been shown to improve QoL.

Effects of weight loss and sarcopenia on response to chemotherapy, quality of life, and survival.

It has frequently been shown that patients with cancer are one of the largest hospital patient groups with a prevalence for malnutrition. Weight loss is a frequent manifestation of malnutrition in patients with cancer. Several large-scale studies over the past 35 y have reported that involuntary weight loss affects 50% to 80% of these patients with the degree of weight loss dependent on tumor site and type and stage of disease. The aim of this review was to determine the consequences of malnutrition, weight loss, and muscle wasting in relation to chemotherapy tolerance, postoperative complications, quality of life, and survival in patients with cancer. The prognostic impact of weight loss on overall survival has long been recognised with recent data suggesting losses as little as 2.4% predicts survival independent of disease, site, stage or performance score. Recently the use of gold-standard methods of body composition assessment, including computed tomography, have led to an increased understanding of the importance of muscle abnormalities, such as low muscle mass (sarcopenia), and more recently low muscle attenuation, as important prognostic indicators of unfavourable outcomes in patients with cancer. Muscle abnormalities are highly prevalent (ranging from 10-90%, depending on cancer site and the diagnostic criteria used). Both low muscle mass and low muscle attenuation have been associated with poorer tolerance to chemotherapy; increased risk of postoperative complications; significant deterioration in a patients' performance status, and poorer psychological well-being, overall quality of life, and survival.

High concordance of BRAF mutational status in matched primary and metastatic melanoma.

BACKGROUND: Techniques for the accurate identification of activating mutations of BRAF in metastatic melanoma are of great clinical importance, due to the availability of targeted therapies for these tumors. There is uncertainty regarding the frequency with which BRAF status differs between primary and metastatic sites. METHODS: Between 2011 and 2016, 219 melanoma cases underwent BRAF testing in our institution. In 53 of these cases, paired primary and metastatic specimens were available for polymerase chain reaction (PCR) and immunohistochemical evaluation. RESULTS: Fifty-two out of 53 cases (98%) showed concordant BRAF status between primary and metastatic site by immunohistochemistry (IHC). In one case, a metastasis and its matched primary were positive by IHC, but the metastasis was negative on PCR. On further investigation, PCR was positive in the primary, and repeat PCR in the metastasis was positive, following macrodissection. CONCLUSIONS: Our results suggest that discordance of BRAF mutational status between primaries and metastases is a rare occurrence. In one case, IHC provided strong evidence that initial PCR testing had provided a false-negative result due to low tumor volume. Thus, in cases where tissue is difficult to obtain from a metastasis or unavailable, the primary tumor can be used with confidence.
