Palliative non-small cell lung cancer treatment and end-of-life care stratified by sex and childlessness: an important interplay in unmarried patients?

PurposeTo analyze the interplay of sex and presence of children in unmarried patients with non-small cell lung cancer, because previous studies suggested sex-related disparities. Adult children may participate in treatment decisions and provision of social support or home care.MethodsRetrospective single-institution analysis of 186 unmarried deceased patients, managed according to national guidelines outside of clinical trials. Due to the absence of other oncology care providers in the region and the availability of electronic health records, all aspects of longitudinal care were captured.ResultsEighty-eight female and 98 male patients were included, the majority of whom had children. Comparable proportions in all four strata did not receive active therapy. Involvement of the palliative care team was similar, too. Patients without children were more likely to receive systemic therapy (39% utilization in women with children, 67% in women without children, 41% in men with children, 52% in men without children; p = 0.05). During the last 3 months of life, female patients spent significantly more days in hospital than their male counterparts. Place of death was not significantly different. Home death was equally uncommon in each group. In the multivariate analysis, survival was associated with age and cancer stage, in contrast to sex and presence of children.ConclusionIn contrast to studies from other healthcare systems, unmarried male patients were managed in a largely similar fashion to their female counterparts and with similar survival outcome. Unexpectedly, patients without children more often received systemic anti-cancer treatment.

Comparison of staging laparoscopy for peritoneal metastases with or without Pressurized Intra-Peritoneal Aerosol Chemotherapy (PIPAC)

Background: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) has been introduced for palliative treatment of peritoneal cancer (PC) and is currently tested also in the neoadjuvant and prophylactic setting. The aim was therefore to compare safety and tolerance of staging laparoscopy with or without PIPAC.

Efficacy and safety of 3D printing coplanar template-assisted iodine-125 seed implantation as palliative treatment for inoperable pancreatic cancer.

PurposeTo investigate clinical efficacy and safety of 3D printing coplanar template-assisted iodine-125 (125I) seed implantation as a palliative treatment for inoperable pancreatic cancer.Material and methodsConsecutive 28 patients (16 males and 12 females, median age of 64 years) with histologically diagnosed pancreatic cancer who underwent 3D printing coplanar template-assisted 125I seed implantation between June 2016 and May 2019 were analyzed. Among these 28 patients, 9 (32.1%) and 19 (67.9%) patients were presenting with tumor node metastasis (TNM) stage IIB and stage III cancer, respectively. Seed implantation was conducted for pain palliation intent in 25 patients and recurrent cancer after radiotherapy in 3 patients.ResultsNo significant differences were found between pre-planned and post-operative dosimetric parameters, involving D90, D100, V90, V100, V150, conformity index, external index, and homogeneity index (all p > 0.05). Two months after implantation, pain relief rate was 76% (19/25) for pain patients. Overall tumor response rate (complete response + partial response) was 60.7% (complete response 0 patients, partial response 17 patients, stable disease 8 patients, and progressive disease 3 patients). Median survival was 10.5 months and estimated 1-year survival rate was 26.7%. Only one patient presented with a slightly upper gastro-intestinal hemorrhage, and another patient suffered from incomplete intestinal obstruction soon after implantation, both recovered after conservative medical treatment without a prolonged hospital stay. No major complication was observed.Conclusions3D printing coplanar template-assisted 125I seed implantation appears to be safe and effective palliative treatment for inoperable pancreatic cancer with favorable clinical outcomes.

Dendritic Cell Therapy in the palliative Treatment of Pancreatic Cancer Patients. Experience in 200 Patients

Purpose: Despite improved diagnostic and therapeutic facilities median survival in pancreatic cancer is still unsatisfactory Here we retrospectively analyzed the outcome of immunotherapy in the additional palliative treatment of pancreatic cancer with long antigen exposition dendritic cell therapy (LANEX-DC®) in 200 patients who were treated at our institution (intent-to- treat-analysis). Patients: Data were available of 200 patients.The mean interval between first diagnosis and start of treatment was 1,5 months. 148 patients received one cycle of dendritic cell therapy, 52 patients received 2 or more cycles of dendritic cell therapy. Results: Therapy was well tolerated and no serious side effects were observed. The survival rate after 6 months was 70,9 % and afters 9 month 51,0%. The median survival time according to Kaplan- Meier regression analysis was 9,1 months. Median survival was significantly higher in the group of patients who started immunotherapy within 1,5 months following diagnosis (7,9 months versus11,8 months, p=0,009). Patients with two or more cycles of dendritic cell therapy lived significantly longer than patients with just one cycle (17,5 months versus 7,4 months, p=0,001). Interestingly younger patients < 65 years of age lived significantly longer as patients >= 65 years of age (p = 0,004). Conclusion: We were able to demonstrate in a large retrospective cohort analysis that additional treatment with dendritic cells is highly effective and extends the median survival times up to 17,5 months in case of regular repetition of dendritic cell therapy. Furthermore, we were able to demonstrate that median survival can be increased by early beginning dendritic cell therapy.

Role of GPs in shared decision making with patients about palliative cancer treatment: a qualitative study in the Netherlands.

BackgroundGPs are well placed to enhance shared decision making (SDM) about treatment for patients with advanced cancer. However, to date, little is known about GPs’ views about their contribution to SDM.AimTo explore GPs’ perspectives on their role in SDM about palliative cancer treatment and the requirements they report to fulfil this role.Design and settingQualitative interview study among Dutch GPs.MethodGPs were sampled purposefully and conveniently. In-depth, semi-structured interviews were conducted, recorded, and transcribed verbatim. Transcripts were analysed by thematic analysis.ResultsFifteen GPs took part in this study. Most of them reported practices that potentially support SDM: checking the quality of a decision, complementing SDM, and enabling SDM. Even though most of the GPs believed that decision making about systemic cancer treatment is primarily the oncologist’s responsibility, they did recognise their added value in the SDM process because of their gatekeeper position, the additional opportunity they offer patients to discuss treatment decisions, and their knowledge and experience as primary healthcare providers at the end of life. Requirements for them to support the SDM process were described as: good collaboration with oncologists; sufficient information about the disease and its treatment; time to engage in conversations about treatment; a trusting relationship with patients; and patient-centred communication.ConclusionGPs may support SDM by checking the quality of a decision and by complementing and enabling the SDM process to reach high-quality decisions. This conceptualisation of the GP’s supporting role in SDM may help us to understand how SDM is carried out through interprofessional collaboration and provide tools for how to adopt a role in the interprofessional SDM process.

Jejunostomy in the palliative treatment of gastric cancer: A clinical prognostic score

BACKGROUNDClinical stage IV gastric cancer (GC) may need palliative procedures in the presence of symptoms such as obstruction. When palliative resection is not possible, jejunostomy is one of the options. However, the limited survival of these patients raises doubts about who benefits from this procedure.AIMTo create a prognostic score based on clinical variables for 90-d mortality for GC patients after palliative jejunostomy. METHODSWe performed a retrospective analysis of Stage IV GC who underwent jejunostomy. Eleven preoperative clinical variables were selected to define the score categories, with 90-d mortality as the main outcome. After randomization, patients were divided equally into two groups: Development (J1) and validation (J2). The following variables were used: Age, sex, body mass index (BMI), American Society of Anesthesiologists classification (ASA), Charlson Comorbidity index (CCI), hemoglobin levels, albumin levels, neutrophil-lymphocyte ratio (NLR), tumor size, presence of ascites by computed tomography (CT), and the number of disease sites. The score performance metric was determined by the area under the receiver operating characteristic (ROC) curve (AUC) to define low and high-risk groups.RESULTSOf the 363 patients with clinical stage IVCG, 80 (22%) patients underwent jejunostomy. Patients were predominantly male (62.5%) with a mean age of 62.4 years old. After randomization, the binary logistic regression analysis was performed and points were assigned to the clinical variables to build the score. The high NLR had the highest value. The ROC curve derived from these pooled parameters had an AUC of 0.712 (95%CI: 0.537–0.887, P = 0.022) to define risk groups. In the validation cohort, the diagnostic accuracy for 90-d mortality based on the score had an AUC of 0.756, (95%CI: 0.598–0.915, P = 0.006). According to the cutoff, in the validation cohort BMI less than 18.5 kg/m2 (P < 0.001), CCI ≥ 1 (P = 0.001), ASA III/IV (P = 0.002), high NLR (P = 0.012), and the presence of ascites on CT exam (P = 0.004) were significantly associated with the high-risk group. The risk groups showed a significant association with first-line (P = 0.012), second-line chemotherapy (P = 0.009), 30-d (P = 0.013), and 90-d mortality (P < 0.001).CONCLUSIONThe scoring system developed with 11 variables related to patient’s performance status and medical condition was able to distinguish patients undergoing jejunostomy with high risk of 90 d mortality.

A Possible Distinct Molecular Subtype (Quintuple-Wildtype) of Metastatic Colorectal Cancer in First-Line Anti-EGFR Therapy with Cetuximab Plus FOLFIRI – Palliative Precision Therapy and a Multidisciplinary Treatment Approach: Interim Analysis of the IVOPAK II Trial with Early Results

Objective: The study aimed to prospectively evaluate a new molecular biomarker panel (KRAS, NRAS, BRAF, PIK3CA, and ERBB2) for palliative first-line treatment of colorectal cancer (CRC), including a multidisciplinary treatment approach. The rate of secondary metastasis resections was assessed. Patients and Methods: A total of 40 patients with definitively nonresectable metastatic CRC were enrolled from 10 centers before the interim analysis (June 2019) of the IVOPAK II trial (Interdisciplinary Care with Quality Control in Palliative Treatment of Colorectal Cancer). After determination of 5 molecular biomarkers in the tumor (KRAS, exons 2–4; NRAS, exons 2–4; BRAF V600E; PIK3CA; and ERBB2), patients in the IVOPAK II study received FOLFIRI plus cetuximab for all-RAS/quintuple-wildtype disease and FOLFIRI plus bevacizumab in the case of RAS mutations. The current article presents the early description of the clinical outcome of the interim analysis of IVOPAK II comparing the all-RAS/quintuple-wildtype and RAS-mutations populations, including a multidisciplinary-treated case report of a quintuple-wildtype patient. Results: The quintuple-wildtype population treated with FOLFIRI plus cetuximab in first-line exhibited a significantly higher response rate and enhanced early tumor shrinkage in the interim analysis than the RAS-mutations population, as well as a high rate of secondary metastatic resections. Conclusion: Initial results of this new biomarker panel (quintuple-wildtype) are promising for anti-EGFR therapy with cetuximab plus doublet chemotherapy (FOLFIRI) in first-line treatment of metastatic CRC. These results warrant confirmation with higher case numbers in the IVOPAK II trial.

Incidental Diagnosis of Metastatic Prostate Cancer Post-Inguinal Hernia Repair

This report discusses the case of an 83-year-old male who was incidentally found to have a diagnosis of metastatic prostate cancer on pathology from elective inguinal hernia repair. The medical record, radiology, operative reports, and pathology of the patient were reviewed and a literature search was subsequently performed. A new cancer diagnosis is a very rare finding during routine hernia surgery. Moreover, the decision of whether to send a hernia sac for routine pathology is often dependent on individual surgeon practices and institutional guidelines. However, this case demonstrates the potential for an unexpected finding on routine pathology to significantly alter the clinical course of a patient's care as the patient subsequently underwent both medical and palliative surgical treatment for prostate cancer.

Experiences of bereaved family caregivers with shared decision making in palliative cancer treatment: a qualitative interview study

BackgroundPatients with incurable cancer face complex medical decisions. Their family caregivers play a prominent role in shared decision making processes, but we lack insights into their experiences. In this study, we explored how bereaved family caregivers experienced the shared decision making process.MethodsWe performed a qualitative interview study with in-depth interviews analysed with inductive content analysis. We used a purposive sample of bereaved family caregivers (n = 16) of patients with cancer treated in a tertiary university hospital in the Netherlands.ResultsFour themes were identified: 1. scenarios of decision making, 2. future death of the patient 3. factors influencing choices when making a treatment decision, and 4. preconditions for the decision making process. Most family caregivers deferred decisions to the patient or physician. Talking about the patient’s future death was not preferred by all family caregivers. All family caregivers reported life prolongation as a significant motivator for treatment, while the quality of life was rarely mentioned. A respectful relationship, close involvement, and open communication with healthcare professionals in the palliative setting were valued by many interviewees. Family caregivers’ experiences and needs seemed to be overlooked during medical encounters.ConclusionsFamily caregivers of deceased patients with cancer mentioned life prolongation, and not quality of life, as the most important treatment aim. They highly valued interactions with the medical oncologist and being involved in the conversations. We advise medical oncologists to take more effort to involve the family caregiver, and more explicitly address quality of life in the consultations.

Aluminium (III) phthalocyanine chloride tetrasulphonate is an effective photosensitizer for the eradication of lung cancer stem cells

Cancer stem cells (CSCs) are considered to contribute to the recurrence of lung cancer due to their stem-like nature and the involvement of genetic markers associated with drug efflux, regeneration and metastases. Photodynamic therapy (PDT) is a cost-effective and non-invasive therapeutic application that can act as an alternative therapy for lung cancer when considering CSC involvement. Stem-like cells derived from the A549 lung cancer cell line, positive for CD133, CD56 and CD44 antigen markers, were characterized, intracellular localization of aluminium (III) phthalocyanine chloride tetrasulphonate (AlPcS4Cl) determined and its anti-cancer PDT effects were evaluated. Results confirmed that isolated cells were stem cell-like and subcellular localization of AlPcS4Cl in integral organelles involved in cell homeostasis supported the destruction of CSC. AlPcS4Cl's effectivity was demonstrated with CSC eradication showing a significant increase in cytotoxicity and cell death via apoptosis, caused by a decrease in mitochondrial membrane potential. PDT could serve as a palliative treatment for lung cancer and improve prognosis by elimination of lung CSCs.

Long-term changes in nutritional status and body composition in patients with malignant pancreatic disease - A systematic review.

Patients with pancreatic cancer often experience significant deterioration in nutritional status over time. Malnutrition is complex and multifactorial, with malabsorption, pain, toxic dependencies, co-morbidities and malignant processes all playing a role. The aims of this systematic review were to assess nutritional changes over time and identify tolerance of nutritional intervention, thus identifying potential areas for further research to improve patient outcomes. A systematic review of MEDLINE, EMBASE and PubMed was carried out in February 2020, identifying 2620 articles. After screening to exclude those reporting short-term measures, with only one data point, or in the wrong population, thirteen papers were selected for analysis (four trials in neo-adjuvant treatment, five in populations undergoing palliative treatment for pancreatic cancer, and four in mixed populations undergoing pancreatic resection). Overall, studies were limited by predominantly retrospective designs, and poor control of potentially confounding variables. Meta-analysis could not be performed due to heterogenicity in study design and reporting methods. Surgery in mixed cohorts did not appear to result in weight loss. Only one small intervention study was identified. Patients with pancreatic cancer experienced a decline in nutritional status, with 44-63% of patients undergoing neoadjuvant chemotherapy having low muscle mass prior to starting treatment. There is a paucity of data regarding nutritional intervention in pancreatic cancer. Future work should include the use of validated functional and clinical assessment tools to further explore the impact of nutritional intervention, and the relationship between nutritional status and outcome.

ACCEPT®: A Complementary Anthroposophical Program for the Palliative Treatment of Lung Cancer – Rationale and a Randomized Feasibility Study

Background: Lung cancer is the oncological disease with the highest mortality worldwide. Health-related quality of life is severely compromised in the majority of patients. While the efficacy of early palliative psychosocial therapy has been demonstrated in several recent studies, appropriate therapy modules could so far not be integrated into daily practice of care. Therefore, an additive multimodal treatment concept for oncological centers was drafted: the Additive anthroposophic integrative medicine Cancer Concept of Early supportive or Palliative lung cancer Treatment (ACCEPT®). Patients and Methods: The first module consisted of a 3-month health education program, the second module was a concept of psychosocial interventions, and the third module was a supervised home training program. Between 2017 and 2018, 20 lung cancer patients (UICC IIIB/IV) were included and randomly assigned to treatment (n = 10) or a waiting control group (n = 10). The treatment group started ACCEPT® for 3 months immediately after diagnosis and received also standard oncological care (SOC) while the waiting control group received SOC only for 3 months, followed by ACCEPT® after this period. Health-related quality of life, disease management, disease-specific symptoms, and feasibility of the ACCEPT® were monitored at 4 time points. Results: 7 out of 10 patients in the treatment group (3 dropped out) and 6 out of 10 in the waiting control group (4 died during the intervention) completed treatment. Discussion/Conclusion: Lung cancer patients with high symptom load may benefit from ACCEPT®. The feasibility of this adjunctive therapy was demonstrated. The combination of SOC and ACCEPT® is feasible and applicable to a heterogeneous patient group and should be further evaluated with respect to efficacy and dosing.

Oral etoposide as a single agent in childhood and young adult cancer in England: Still a poorly evaluated palliative treatment.

Oral etoposide is commonly used in palliative treatment of childhood and young adult cancer without robust evidence. We describe a national, unselected cohort of young people in England treated with oral etoposide using routinely collected, population-level data. Patients aged under 25years at cancer diagnosis (1995-2017) with a treatment record of single-agent oral etoposide in the Systemic AntiCancer Dataset (SACT, 2012-2018) were identified, linked to national cancer registry data using NHS number and followed to 5 January 2019. Overall survival (OS) was estimated for all tumours combined and by tumour group. A Cox model was applied accounting for age, sex, tumour type, prior and subsequent chemotherapy. Total 115 patients were identified during the study period. Mean age was 11.8years at cancer diagnosis and 15.5years at treatment with oral etoposide. Median OS was 5.5months from the start of etoposide; 13 patients survived beyond 2years. Survival was shortest in patients with osteosarcoma (median survival 3.6months) and longest in CNS embryonal tumours (15.5months). Across the cohort, a median of one cycle (range one to nine) of etoposide was delivered. OS correlated significantly with tumour type and prior chemotherapy, but not with other variables. This report is the largest series to date of oral etoposide use in childhood and young adult cancer. Most patients treated in this real world setting died quickly. Despite decades of use, there are still no robust data demonstrating a clear benefit of oral etoposide for survival.

Surveying the Challenges to Improve Linear Accelerator-based Radiation Therapy in Africa: a Unique Collaborative Platform of All 28 African Countries Offering Such Treatment

Radiation therapy is a critical component for curative and palliative treatment of cancer and is used in more than half of all patients with cancer. Yet there is a global shortage of access to this treatment, especially in Sub-Saharan Africa, where there is a shortage of technical staff as well as equipment. Linear accelerators (LINACs) offer state-of-the-art treatment, but this technology is expensive to acquire, operate and service, especially for low- and middle-income countries (LMICs), and often their harsh environment negatively affects the performance of LINACs, causing downtime.A global initiative was launched in 2016 to address the technology and system barriers to providing radiation therapy in LMICs through the development of a novel LINAC-based radiation therapy system designed for their challenging environments. As the LINAC prototype design phase progressed, it was recognised that additional information was needed from LMICs on the performance of LINAC components, on variables that may influence machine performance and their association, if any, with equipment downtime. Thus, a survey was developed to collect these data from all countries in Africa that have LINAC-based radiation therapy facilities. In order to understand the extent to which these performance factors are the same or different in high-income countries, facilities in Canada, Switzerland, the UK and the USA were invited to participate in the survey, as was Jordan, a middle-income country. Throughout this process, LMIC representatives have provided input on technology challenges in their respective countries.This report presents the method used to conduct this multilevel study of the macro- and microenvironments, the organisation of departments, the technology, the training and the service models that will provide input into the design of a LINAC prototype for a LINAC-based radiation therapy system that will improve access to radiation therapy and thus improve cancer treatment outcomes. It is important to note that new technology should be introduced in a contextual manner so as not to disrupt existing health systems inadvertently, especially with regards to existing staffing, infrastructure and socioeconomic issues. A detailed analysis of data is underway and will be presented in a follow-up report. Selected preliminary results of the study are the observation that LINAC-based facilities in LMICs experience downtime associated with failures in multileaf collimators and vacuum pumps, as well as power instability. Also, that there is a strong association of gross national product per capita with the number of LINACs per population.

MO153RENAL FUNCTIONS OUTCOME IN METASTATIC NON SMALL LUNG CARCINOMA PATIENTS: THE RISK OF AKI IN FIRST LINE THERAPY

Abstract Background and Aims The optimal use of immune and target therapies, the optimal use of standard chemotherapy (CT) is of paramount importance, especially for patients affected by chronic kidney disease (CKD) who require dose adjustment according to the glomerular filtration rate (GFR) to avoid acute kidney injury (AKI) establishment. Immune checkpoint inhibitors (ICIs) and platinum-based chemotherapy (CT) are options for the palliative treatment of metastatic non-small cell lung cancer (NSCLC). Recently, CT in combination with immune-checkpoint inhibitors has become the treatment of choice for this setting of patients. Therefore, it is fundamental to investigate the potential nephrotoxic effects of both treatments and their potential additive effects on renal function. Aim of our study was to compare the nephrotoxic effect of both ICIs and CT (cisplatin and carboplatin-based) in a consecutive cohort of patients affected by metastatic NSCLC. Method A consecutive cohort of 126 patients treated in first-line for NSLCL was enrolled in a single tertiary Hospital between 2018 and 2020. Inclusion criteria were: age (&amp;gt; 18 years old), eGFR (&amp;gt; 15 ml/min/1.73), histological diagnosis of metastatic NSCLC. Each patient underwent immunotherapy or CT according to clinical conditions, comorbidities and programmed death ligand 1 (PD-L1) expression status. eGFR (using CKD-EPI formula 2009) was detected at baseline and after each cycle of immunotherapy or CT (using cisplatin or carboplatin) in order to determine the correct renal status using the K-DIGO 2012 guidelines for AKI stages and CKD classes. Pts were subdivided into CKD categories G according to their eGFR values before and after the treatment. AKI onset was evaluated by rise in creatine levels according to K-DIGO criteria. Clinical stage according to cTNM (AJCC TNM system-2019) was collected at baseline before the first treatment. Comorbidities (e.g., diabetes, blood hypertension, overweight and obesity) were also included. Comparison between numerical variables was performed using linear regressions; between groups using Kruskal-Wallis rank sum test for numerical variables and Pearson’s Chi square test for categorical variables. Log rank test was used to test differences between groups in terms of AKI onset during the therapy. Results Clinical and pathological characteristics are reported in table 1. From the analysis, no significative differences were detected between Immunotherapy and CT group for age, gender, basal serum creatinine, basal eGFR, basal BMI, diagnosis of diabetes, hypertension, basal CKD G group or overall AKI onset. Treatment cycles were significantly different between the two groups (p&amp;lt;0.001) with a short median number of cycles for the CT group. No significative difference in terms of decay of eGFR calculated as final-basal values was detected (p=0.8). AKI onset over cycles was significantly different between the two groups (p=0.02), observing a higher risk of developing earlier AKI for CT group (cisplatin or carboplatin) (13,9%) with respect to immunotherapy (7,4%) (figure 1 and 2). Conclusion Our study highlights that both cisplatin and carboplatin-based CT displays an augmented incidence of AKI development after a lower number of therapy cycles in respect of immunotherapy. The nephrotoxic effects of combined therapy for NSLCL should be always evaluated by nephrologist during the treatment of NSLCL patients to avoid an augmented risk of AKI derived from the combination of immunotherapy and CT in first line.

General treatment for metastatic colorectal cancer: From KEYNOTE 177 study

In the palliative treatment of metastatic colorectal cancer (mCRC), doublet chemotherapy (FOLFOX or FOLFIRI) or triplet chemotherapy (FOLFOXIRI) combined with targeted drugs (cetuximab or bevacizumab) is the main regimen. Recently, microsatellite instability-high (MSI-H) or DNA mismatch repair deficient (dMMR) was discovered as a biomarker to distinguish immunotherapy-benefited populations. In this context, recently published randomized phase III clinical trials tested the efficacy and safety of immunotherapy and traditional chemotherapy with or without targeted drugs as first-line treatment for patients with MSI-H/dMMR mCRC.Here, we briefly analyze this article and further discuss immune monotherapy or double immunotherapy for patients with MSI-H/dMMR mCRC, the immunotherapy for patients with BRAF V600E mutant mCRC, and the immunotherapy for patients with microsatellite stable mCRC.

Bridging the gap: a pre-post feasibility study of embedding exercise therapy into a co-located cancer unit.

PurposeTo establish the feasibility of embedding a flexible, exercise-based rehabilitation program into a cancer treatment unit to allow cancer survivors early exercise support.MethodA pre-post study was conducted using Bowen’s Framework to describe key domains of feasibility: demand (referrals), acceptability (uptake, attendance, satisfaction), implementation (resources), practicality (adverse events, costs) and limited-efficacy (function, quality of life, self-efficacy). Participants were medically stable, adult cancer survivors receiving curative or palliative treatment for cancer at the health service. Participants completed an 8-week home or hospital-based exercise program. Data were analysed descriptively. Standardised mean differences (Hedge’s g) and mean differences were calculated to determine effect size and clinical significance.ResultsThe exercise-based rehabilitation service received 155 referrals over 6 months. Of those eligible, 73/119 (61%) commenced. Participants opting for twice-weekly, hospital-based exercise attended 9/16 (56%) sessions. Participants reported high satisfaction and there were no major adverse events. The program utilised existing resources, with the predominant cost being staff. The average health service cost per participant was AUD $1,104. Participants made clinically significant gains in function (6-min walk distance; + 73 m, 95% confidence interval 49 to 96) and quality of life (EORTC QLQ-C30 Global quality of life; + 8 units, 95% confidence interval 3 to 13).ConclusionImplementation of exercise-based rehabilitation in a co-located cancer unit was safe and feasible. Access, patient and staff education and establishing funding streams are important implementation considerations.Implications for cancer survivorsAccess to exercise in a cancer unit provides opportunity for early intervention to optimise function during treatment.Supplementary InformationThe online version contains supplementary material available at 10.1007/s00520-021-06261-2.

Does systemic anti-tumor therapy increase COVID-19 risk in patients with cancer?

PurposeWe aimed to determine the COVID-19 infection rate and determine the factors that affect hospitalization and prognosis in patients receiving systemic chemotherapy (CT), immunotherapy (IT) and molecular-targeted therapies at our hospital within three months after the onset of COVID-19 pandemic.Materials and methodsThe patients who received systemic treatment at chemotherapy unit with diagnosis of cancer between 11 March 2020 and 11 June 2020 were included. The clinical and demographic characteristics of patients, the systemic treatments that they received (CT, IT, targeted therapies), and the stage of disease were determined. For the parameters that affect the hospitalization of COVID-19 infected patients were also determined.ResultsAmong 1149 patients with cancer, 84 of them were infected with COVID-19, and the median age of infected patients was 61.0 (IQR: 21–84) and 60.7% of them were male. As a subtype of cancers lung cancer was more frequent in the patients who infected with COVID compared with non-infected ones and the difference was statistically significant when the underlying malignities were compared (32.1% vs 19.0%, p = 0.031). The hospitalization rate and receiving COVID-19 treatment were more frequent in metastatic patients who were receiving palliative therapy, and the difference was statistically significant (p = 0.01, p = 0.03). In our study, infection rate was similar among patients treated with CT, IT and CT plus targeted therapy; however, fewer COVID-19 infections were seen at patients who received only targeted therapy.ConclusionCOVID-19 infection is more frequent in cancer patients and tends to be more severe in metastatic cancer patients receiving anticancer treatment, and the continuation of palliative cancer treatments in these patients may cause increased cancer and infection-related morbidity and mortality.

Can Long-Standing GnRH Therapy Cause a Pituitary Prolactinoma?

Abstract Background: Pituitary adenoma (PA) is the most common cause of sellar masses and accounts for about 10% of all intracranial tumors. Several physiological, pathological, drugs, and rare causes like hypothyroidism can cause PA. We describe a case of long-standing treatment with GnRH analogues possibly contributing to development of PA. Clinical Case: An 86-year-old man with a history of prostate cancer (PC) treated with medical therapy, presented to the hospital with progressively worsening loss of vision in his right eye associated with low-grade headaches over the past few years. Fifteen years prior to presentation, the patient was diagnosed with Gleason 6 (3 + 3) localized PC. He had refused surgical intervention and hence was treated with flutamide, then leuprolide. Labs were significant for an elevated prolactin 34.2 ng/mL [n= 2.5 -17.4], low LH 0.7 mIU/mL [n=1.2-10.6], with normal FSH, TSH, ACTH, IGF, Cortisol, and PTH. CT head and MRI brain identified a 2.7cm x 2.6.3 cm X 1.7 cm mass in the suprasellar region involving the left cavernous sinus and right optic chiasm. These findings were consistent with a diagnosis of Prolactinoma. Patient refused surgery and hence was started on bromocriptine. The findings were suspected to be secondary to long-standing GnRH agonist therapy, and leuprolide was discontinued. DEXA scan confirmed osteoporosis with a T score of --2.5, which was treated with denosumab. Subsequently his vision improved. The patient continues to follow with endocrinology for the management of osteoporosis and prolactinoma. Conclusion: Primary hypothyroidism predisposes to PA due to loss of thyroxine feedback inhibition to hypothalamus with overproduction of TRH with hyperplasia of lactotrophs. We speculate that constant stimulation of the pituitary by GnRH analogues can also lead to enlargement of the anterior pituitary in a similar fashion, and can lead to the development of prolactinoma. LHRH agonists such as Leuprolide, as palliative treatment for advanced prostate cancer, causes desensitization of the anterior pituitary and decreases the production of LH and FSH, which ultimately leads to decreased testosterone in males. Although not standard of care for treatment of locally advance tumors, medical therapy was chosen in this patient’s case due to refusal of surgical intervention. He then developed a clinically significant pituitary adenoma years after the therapy. We suggest that constant stimulation of the pituitary by GnRH analogues can lead to enlargement of the anterior pituitary in a similar fashion, resulting in the development of the prolactinoma.

Gemcitabine/nab-Paclitaxel versus FOLFIRINOX for palliative first-line treatment of advanced pancreatic cancer: A propensity score analysis

BackgroundGemcitabine/nab-paclitaxel (GN) and FOLFIRINOX are standard first-line treatment options for advanced pancreatic ductal adenocarcinoma (aPDAC), but currently no prospective randomised head-to-head comparison between these treatments has yet been performed. MethodsWe conducted a comparative propensity score (PS) analysis of overall (OS) and progression-free survival (PFS) in a tri-centre cohort of patients with aPDAC undergoing palliative first-line treatment with either GN or FOLFIRINOX. ResultsIn unadjusted analysis, OS and PFS were highly similar between patients treated with GN (n = 297) and FOLFIRINOX (n = 158). In detail, median, 1- and 2-year OS estimates were 10.1 months, 42% and 18% in the GN group, as compared to 11.2 months, 45% and 12% in the FOLFIRINOX group, respectively (log-rank p = 0.783). Accordingly, median (4.6 versus 4.8 months), 6-month (40% versus 43%) and 1-year (9% versus 9%) PFS estimates did not significantly differ (log-rank p = 0.717). However, patients treated with FOLFIRINOX were significantly younger, had fewer comorbidities, and a better Eastern Cooperative Oncology Group performance status. These imbalances were accounted for by weighting the data with the PS. In PS analysis of survival outcomes, OS and PFS remained comparable between the two treatment groups. In detail, PS-weighted median, 1- and 2-year OS estimates were 10.1 months, 42% and 18% in the GN group, as compared to 10.1 months, 40% and 13% in the FOLFIRINOX group (PS-weighted log-rank p = 0.449). PS-weighted PFS estimates again did not differ (PS-weighted log-rank p = 0.329). ConclusionThis real-world comparative effectiveness study indicates that FOLFIRINOX and GN have similar effectiveness in the palliative first-line treatment of aPDAC.
