Combined chemotherapy and endoscopic ultrasound-guided intratumoral 32P implantation for locally advanced pancreatic adenocarcinoma: a pilot study.

BACKGROUND: This study evaluated clinical outcomes of combined chemotherapy and endoscopic ultrasound (EUS)-guided intratumoral radioactive phosphorus-32 (32P) implantation in locally advanced pancreatic adenocarcinoma (LAPC). METHODS: Consecutive patients with newly diagnosed LAPC were recruited over 20 months. Baseline computed tomography and 18F-2-fluoro-2-deoxy-D-glucose (18FDG) positron emission tomography-computed tomography were performed and repeated after 12 weeks to assess treatment response. Following two cycles of conventional chemotherapy, patients underwent EUS-guided 32P implantation followed by six chemotherapy cycles. RESULTS: 12 patients with LAPC (median age 69 years [interquartile range 61.5-73.3]; 8 male) completed treatment. Technical success was 100 % with no procedural complications. At 12 weeks, median reduction in tumor volume was 8.2 cm3 (95 % confidence interval 4.95-10.85; P = 0.003), with minimal or no 18FDG uptake in nine patients (75 %). Tumor downstaging was achieved in six patients (50 %), leading to successful resection in five (42 %), including four R0 resections (80 %). CONCLUSIONS: EUS-guided 32P implantation was feasible, well tolerated, and resulted in a 42 % surgical resection rate. Further evaluation in a larger randomized multicenter trial is warranted.

Polypharmacy cut-points in older people with cancer: how many medications are too many?

PURPOSE: Polypharmacy is often defined as use of 'five-or-more-medications'. However, the optimal polypharmacy cut-point for predicting clinically important adverse events in older people with cancer is unclear. The aim was to determine the sensitivities and specificities of a range of polypharmacy cut-points in relation to a variety of adverse events in older people with cancer. METHODS: Data on medication use, falls and frailty criteria were collected from 385 patients aged ≥70 years presenting to a medical oncology outpatient clinic. Receiver operating characteristic (ROC) curves were produced to examine sensitivities and specificities for varying definitions of polypharmacy in relation to exhaustion, falls, physical function, Karnofsky Performance Scale (KPS) and frailty. Sub-analyses were performed when stratifying by age, sex, comorbidity status and analgesic use. RESULTS: Patients had a mean age of 76.7 years. Using Youden's index, the optimal polypharmacy cut-point was 6.5 medications for predicting frailty (specificity 67.0 %, sensitivity 70.0 %), physical function (80.2 %, 49.3 %) and KPS (69.8 %, 52.1 %), 5.5 for falls (59.2 %, 73.0 %) and 3.5 for exhaustion (43.4 %, 74.5 %). For polypharmacy defined as five-or-more-medications, the specificities and sensitivities were frailty (44.9 %, 77.5 %), physical function (58.0 %, 69.7 %), KPS (47.7 %, 69.4 %), falls (44.5 %, 75.7 %) and exhaustion (52.6 %, 64.1 %). The optimal polypharmacy cut-points were similar when the sample was stratified by age, sex, comorbidity status and analgesic use. CONCLUSIONS: Our results suggest that no single polypharmacy cut-point is optimal for predicting multiple adverse events in older people with cancer. In this population, the common definition of five-or-more-medications is reasonable for identifying 'at-risk' patients for medication review.

Sociodemographic disparities in survival from colorectal cancer in South Australia: a population-wide data linkage study.

BACKGROUND: Inequalities in survival from colorectal cancer (CRC) across socioeconomic groups and by area of residence have been described in various health care settings. Few population-wide datasets which include clinical and treatment information are available in Australia to investigate disparities. This study examines socio-demographic differences in survival for CRC patients in South Australia (SA), using a population-wide database derived via linkage of administrative and surveillance datasets. METHODS: The study population comprised all cases of CRC diagnosed in 2003-2008 among SA residents aged 50-79 yrs in the SA Central Cancer Registry. Measures of socioeconomic status (area level), geographical remoteness, clinical characteristics, comorbid conditions, treatments and outcomes were derived through record linkage of central cancer registry, hospital-based clinical registries, hospital separations, and radiotherapy services data sources. Socio-demographic disparities in CRC survival were examined using competing risk regression analysis. RESULTS: Four thousand six hundred and forty one eligible cases were followed for an average of 4.7 yrs, during which time 1525 died from CRC and 416 died from other causes. Results of competing risk regression indicated higher risk of CRC death with higher grade (HR high v low =2.25, 95% CI 1.32-3.84), later stage (HR C v A = 7.74, 95% CI 5.75-10.4), severe comorbidity (HR severe v none =1.21, 95% CI 1.02-1.44) and receiving radiotherapy (HR = 1.41, 95% CI 1.18-1.68). Patients from the most socioeconomically advantaged areas had significantly better outcomes than those from the least advantaged areas (HR =0.75, 95% 0.62-0.91). Patients residing in remote locations had significantly worse outcomes than metropolitan residents, though this was only evident for stages A-C (HR = 1.35, 95 % CI 1.01-1.80). These disparities were not explained by differences in stage at diagnosis between socioeconomic groups or area of residence. Nor were they explained by differences in patient factors, other tumour characteristics, comorbidity, or treatment modalities. CONCLUSIONS: Socio-economic and regional disparities in survival following CRC are evident in SA, despite having a universal health care system. Of particular concern is the poorer survival for patients from remote areas with potentially curable CRC. Reasons for these disparities require further exploration to identify factors that can be addressed to improve outcomes.

Oral vinorelbine and cisplatin with concomitant radiotherapy in stage III non-small-cell lung cancer: an open-label phase II multicentre trial (COVeRT study).

Chemoradiotherapy regimens for stage III non-small-cell lung cancer (NSCLC) require ongoing evaluation. This South Australian multicentre prospective phase II study evaluated the safety, activity and outcomes of combination oral vinorelbine and cisplatin administered concurrently with radiotherapy for stage III NSCLC. Consecutive eligible patients received two cycles of oral vinorelbine 50 mg/m day 1 (D1), day 8 (D8) and intravenous cisplatin 50 mg/m D1 and D8 in a 21-day cycle. Chemotherapy was administered concurrently with radiotherapy at 60 Gy in 30 fractions, 2 Gy/fraction to the isocentre, all fields treated daily, 5 days a week over 6 weeks using 10 MV photons and three-dimensional conformal radiotherapy. The primary endpoint was to evaluate the progression-free survival (PFS). The secondary end points were safety, response rates and overall survival (OS). Forty-three eligible patients with stage III NSCLC - comprising 21 squamous cell carcinoma, 18 adenocarcinoma and four large cell carcinoma - were studied. Four patients did not complete the treatment. By intention-to-treat analysis, 25% showed a partial response and 65% had stable disease. None achieved a complete response. Of the 39 patients who completed protocol-specified treatment, 11 (28%) showed a partial response and 28 (72%) had stable disease. The median PFS was 25.2 months and the median OS was 48.3 months. Toxicities were manageable and generally mild, with the majority being either grade 1 (n=38) or grade 2 (n=21). Toxicities were mainly of oesophagitis, pneumonitis, fatigue, nausea and dysphagia. Two cycles of chemotherapy with oral vinorelbine and cisplatin administered concurrently with radical radiation had an acceptable toxicity profile and was active in inoperable stage III NSCLC. PFS and OS outcomes were encouraging. This regimen warrants further investigation.

Phase I study evaluating the safety and efficacy of oral panobinostat in combination with radiotherapy or chemoradiotherapy in patients with inoperable stage III non-small-cell lung cancer.

Panobinostat is a radiosensitizing agent and targets the epigenetics of malignancy. This phase I study evaluated the safety and efficacy of combining oral panobinostat with radiotherapy (RT) or chemoradiotherapy (CRT) in patients with inoperable stage III non-small-cell lung cancer. This study had a parallel dose-escalating design combining oral panobinostat twice a week (dose escalations 20, 30, 45 mg) with either palliative RT (group A) or radical CRT (group B) using a standard chemotherapy protocol of cisplatin and etoposide. In group A (RT), nine recruited patients received treatment with oral panobinostat (doses 20, 30, 45 mg) with RT. Two serious adverse events, rapid atrial fibrillation and tracheo-oesophageal fistula, were not attributable to study treatment. The most common grade 3/4 toxicities were thrombocytopenia and lymphopenia, which resolved promptly after cessation of panobinostat. The disease control rate was 66%, the progression-free survival was 3 months and the median overall survival was 9 months. In group B (CRT), panobinostat dose was not escalated beyond 20 mg because of infection-related complications. Serious adverse events included opportunistic infection associated with treatment-related lymphopenia and febrile neutropenia without a source. One patient had cerebral infarct that was not attributed to study treatment. All patients achieved a partial response to treatment. At 33 months of follow-up, all patients were still alive. Panobinostat can be combined with palliative-dose RT at doses up to 45 mg twice a week with tolerable toxicity. Dose-limiting toxicities prevented the dose escalation of the panobinostat with CRT.

Prevalence and factors associated with polypharmacy in older people with cancer.

PURPOSE: Polypharmacy has been associated with drug-drug interactions, adverse drug events, hospitalisation and increased mortality. The purpose of this study was to investigate the prevalence and factors associated with polypharmacy in older people with cancer. PATIENTS AND METHODS: Patients aged≥70 years (n=385) presenting to the medical oncology outpatient clinic at Royal Adelaide Hospital between January 2009 and July 2010 completed a structured data collection instrument. The instrument included domains related to medications, diagnoses, instrumental activities of daily living (IADLs), Karnofsky Performance Scale (KPS), physical function (SF-36), pain (ten-point visual analogue scale, VAS), weight loss (patient self-reported over previous 6 months), exhaustion (CES-D) and distress (ten-point VAS). Frailty was computed using Fried's frailty phenotype. Logistic regression was used to compute unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the association between polypharmacy (defined as five or more self-reported daily medications) and clinical parameters. RESULTS: Polypharmacy was present in 57% (n=221) of patients. When adjusting for age, gender and Charlson Comorbidity Index (CCI), polypharmacy was associated with being pre-frail (OR=2.35, 95%CI=1.43-3.86) and frail (OR=4.48, 95%CI=1.90-10.54) compared to being robust. When adjusting for age, gender, exhaustion, KPS, IADLs, pain and distress, polypharmacy was associated with higher CCI scores (OR=1.58, 95%CI=1.29-1.94) and poorer physical function (OR=1.13, 95%CI=1.06-1.20). CONCLUSIONS: Polypharmacy is highly prevalent in older people with cancer and associated with impaired physical function and being pre-frail and frail compared to being robust. Research is needed to identify strategies to minimize patients' medication regimens.

A descriptive study of persistent oxaliplatin-induced peripheral neuropathy in patients with colorectal cancer.

BACKGROUND: Prolonged neurotoxicity after systemic chemotherapy has the potential to impact on quality of life. We explored the frequency of persistent peripheral neuropathy in patients who received oxaliplatin for colorectal cancer at two local centres. PATIENTS AND METHODS: Questionnaires were sent to patients who completed treatment with oxaliplatin for colorectal cancer at least 20 months prior to entering the study. Neuropathy questions were adapted from the FACT/GOG-Ntx (V.4) questionnaire. RESULTS: Of the 56 eligible patients, 27 returned the questionnaire. Twenty-five patients (93 %) experienced neuropathic symptoms during their treatment; 11 had grade-2, and two had grade-3 symptoms. At the time of completing the questionnaire, 17 patients (63.0 %; 95%CI 43.9-79.4 %) were still symptomatic with 12 patients (44.4 %; 95%CI 26.8-63.3) having grade-2 or grade-3 symptoms and three patients (11.1 %; 95%CI 2.9-27.3) having grade-3 neuropathic symptoms. Participants who received more than 900 mg/m2 oxaliplatin had a significantly higher risk of persistent grade-2 or grade-3 neuropathy (p = 0.031, RR = 8.3 95%CI = 1.2-57.4). There was a trend toward increased risk of persistent neuropathy of any grade among participants with a history of regular alcohol use (p = 0.051; RR = 1.7 95%CI 1.0-2.8). CONCLUSION: Persistent oxaliplatin-induced neuropathy is not as uncommon as previously suggested, and the rate of grade-2 and grade-3 symptoms could be considerably higher than previous reports.

Successful Osimertinib Rechallenge After Relapse Following Adjuvant Osimertinib: A Case Report.

Adjuvant osimertinib represents a recent paradigm shift in the management of resected EGFR-mutated lung cancer. The optimal subsequent treatment of patients who relapse after completion of 3 years of adjuvant osimertinib is unknown. Here, we report two cases of complete response to osimertinib rechallenge after relapse from previous adjuvant osimertinib use, and a serial molecular panel exhibiting a lack of acquired resistance mechanisms. Future prospective studies are warranted to confirm the optimal treatment of patients who relapse after previous adjuvant osimertinib.

Elevation of the tumor marker CA19-9 in a pancreatic cancer survivor with benign prostatic hyperplasia: A clinical case report.

Serum carbohydrate antigen 19-9 (CA19-9) is used for recurrence surveillance in patients with resected pancreatic ductal adenocarcinoma (PDAC). This report describes the association of increasing CA19-9 in a male PDAC survivor with presence of prostatic hyperplasia. Unexplained elevation of CA19-9 in male PDAC survivors might be attributable to benign prostatic conditions.

Printing a cure: A tailored solution for localized drug delivery in liver cancer treatment.

Adjuvant chemotherapy is highly recommended for liver cancer to enhance survival rates due to its tendency to recur frequently. Localized drug-eluting implants have gained traction as an alternative to overcome the limitations of systemic chemotherapy. This work describes the development of biodegradable 3D printed (3DP) bilayer films loaded with 5-fluorouracil (5FU) and cisplatin (Cis) with different infill percentages where the 5FU layers were 40%, 30%, and 30% and Cis layers were 10%, 15%, and 10% for films A, B, and C, respectively. The relevant characterization tests were performed, and the drug content of films was 0.68, 0.50, and 0.50 mg of 5FU and 0.39, 0.80, and 0.34 mg of Cis for films A, B, and C, respectively. Cis release was affected by the alterations to the film design, where films A, B, and C showed complete release at 12, 14, and 23 days, respectively. However, 5FU was released over 24 h for all films. The films were stable for up to two weeks after storage at 25 °C/65% relative humidity and four weeks at 4 °C where drug content, tensile strength, FTIR, and thermal analysis results demonstrated negligible alterations. The cytotoxicity of the films was assessed by MTS assays using HepG2 cell lines demonstrating up to 81% reduction in cell viability compared to blank films. Moreover, apoptosis was confirmed by Western Blots and the determination of mitochondrial cell potential, highlighting the potential of these films as a promising approach in adjuvant chemotherapy.

Mesenchymal chondrosarcoma: An Australian multi-centre cohort study.

BACKGROUND: Mesenchymal chondrosarcoma (MCS) is an ultra-rare sarcoma that follows a more aggressive course than conventional chondrosarcoma. This study evaluates prognostic factors, treatments (surgery, chemotherapy, and radiation), and outcomes in an Australian setting. METHODS: We collected demographics, clinicopathological variables, treatment characteristics, and survival status from patients with MCS registered on the national ACCORD sarcoma database. Outcomes include overall survival (OS) and progression-free survival (PFS). RESULTS: We identified 22 patients with MCS between 2001-2022. Median age was 28 (range 10-59) years, 19 (86%) had localised disease at diagnosis of whom 16 had surgery (84%), 11 received radiation (58%), and 10 chemotherapy (53%). Ten (52%) developed recurrence and/or metastases on follow-up and three patients with initial metastatic disease received surgery, radiation, and chemotherapy. At a median follow-up of 50.9  (range 0.4-210) months nine patients had died. The median OS was 104.1 months (95% CI 25.8-182.3). There was improved OS for patients with localised disease who had surgical resection of the primary (p = 0.003) and those with ECOG 0-1 compared to 2-3 (p = 0.023) on univariate analysis. CONCLUSIONS: This study demonstrates contemporary Australian treatment patterns of MCS. The role of chemotherapy for localised disease remains uncertain. Understanding treatment patterns and outcomes help support treatment decisions and design of trials for novel therapeutic strategies.

Managing patients with advanced soft tissue sarcoma: Evolving landscape from an Australian perspective.

AIM: Despite lack of advances in the first-line systemic therapy, the overall survival (OS) has continued to improve in patients with advanced soft tissue sarcoma (STS) with the recent estimation of median OS at 20 months. Several systemic therapy options are available now for the second-line and beyond, with more treatment tailored to histology and molecular subtype. The aim of this retrospective study was to characterize current patterns of care in managing patients with advanced STS (aSTS) in Australia. METHODS: Sarcoma databases from 7 Australian sarcoma services were accessed to identify patients diagnosed with locally advanced inoperable and/or metastatic STS between January 1, 2010 and December 31, 2015. Baseline clinicopathological factors and initial treatment patterns were descriptively analyzed. For the Victorian cohort where treatment of aSTS and follow-up details were available, further exploratory analysis was conducted to determine the impact of patient and tumor characteristics and the use of palliative-intent treatment OS. RESULTS: Of 2261 cases of STS, 671 were deemed as aSTS. Two thirds were relapsed disease with a mean 1.9 years from initial diagnosis. Median age at diagnosis of aSTS was 59 years (18-95 years) and 56.3% was male. Histology classification revealed four main subtypes: undifferentiated pleomorphic sarcoma (UPS) (23.1%), leiomyosarcoma (18.2%), liposarcoma (12.8%), synovial sarcoma (8.2%), and other comprising 14 STS subtypes. For the Victorian cohort (N = 361), approximately 80% of patients accessed palliative-intent treatment of various modalities. Nearly 40% of patients underwent tumor-debulking surgery or metastasectomy, of which lung wedge resection was the most common (N = 83, 47.7%). A total of 438 palliative-intent radiotherapy treatments were delivered to 259 patients (71.7%), with the majority in the form of external beam radiotherapy. Palliative-intent systemic therapy was delivered to 51.5% of patients (N = 186), mostly (73%). Anthracycline-based therapy was the most commonly delivered therapy (N = 135, 72.6%). Approximately half of the patients in each line of therapy failed to proceed to the subsequent line of systemic therapy with 29.4% receiving three or more lines of therapy (N = 55). A total of 18.3% of patient (N = 34) participated in clinical trials or accessed off-label drugs. The median OS for the Victoria cohort was 15.4 months (95% confidence interval: 12.1, 18.2). The UPS histology subtype was associated with poorer OS, whereas receiving any modality of palliative-intent treatment conferred survival benefit. CONCLUSION: In Australia, aSTS is managed with diverse treatment approaches comprising various therapy modalities. Further work is planned in describing healthcare resource utilization and estimating costs by this patient cohort.

Phase I Trial of nab-Paclitaxel Administered Concurrently With Radiotherapy in Patients With Locally Advanced Inoperable Pancreatic Adenocarcinoma.

OBJECTIVES: Nab-paclitaxel has radiosensitizing antitumor efficacy in pancreatic cancer. We aimed to establish maximum tolerated dose (MTD) of nab-paclitaxel with radiotherapy in unresectable locally advanced pancreatic cancer. METHODS: In a phase I dose escalation trial patients received weekly nab-paclitaxel for 6 weeks with external beam radiotherapy (EBRT). 3 + 3 design was used with nab-paclitaxel doses: 25 mg/m 2 (cohort 1), 50 mg/m 2 (cohort 2), 75 mg/m 2 (cohort 3), and 100 mg/m 2 (cohort 4). Primary endpoint was MTD. Secondary objectives were progression-free survival and overall survival. RESULTS: Fourteen patients were recruited. Median age was 69 years (range, 40-86). Grade 1/2 toxicities were nausea (93%), vomiting (54%), diarrhea (57%), and fatigue (69%). There were no dose limiting toxicities (DLT) in cohorts 1 to 3. In cohort 4, DLTs of febrile neutropenia and enterocolitis were observed in patient 1. Subsequent DLT of febrile neutropenia and enterocolitis occurred in patient 5 in the expanded cohort. Following chemoradiotherapy median progression-free survival was 4.7 months (95% confidence interval, 2.5-27.5) and median overall survival was 10.8 months (95% confidence interval, 6.37-25.2). CONCLUSIONS: Nab-paclitaxel and EBRT was well-tolerated at doses below 100 mg/m 2 . The MTD and recommended phase II study dose for nab-paclitaxel with EBRT is 75 mg/m 2 in this disease.

Development of an Australia and New Zealand Lung Cancer Clinical Quality Registry: a protocol paper.

INTRODUCTION: Lung cancer is the leading cause of cancer mortality, comprising the largest national cancer disease burden in Australia and New Zealand. Regional reports identify substantial evidence-practice gaps, unwarranted variation from best practice, and variation in processes and outcomes of care between treating centres. The Australia and New Zealand Lung Cancer Registry (ANZLCR) will be developed as a Clinical Quality Registry to monitor the safety, quality and effectiveness of lung cancer care in Australia and New Zealand. METHODS AND ANALYSIS: Patient participants will include all adults >18 years of age with a new diagnosis of non-small-cell lung cancer (NSCLC), SCLC, thymoma or mesothelioma. The ANZLCR will register confirmed diagnoses using opt-out consent. Data will address key patient, disease, management processes and outcomes reported as clinical quality indicators. Electronic data collection facilitated by local data collectors and local, state and federal data linkage will enhance completeness and accuracy. Data will be stored and maintained in a secure web-based data platform overseen by registry management. Central governance with binational representation from consumers, patients and carers, governance, administration, health department, health policy bodies, university research and healthcare workers will provide project oversight. ETHICS AND DISSEMINATION: The ANZLCR has received national ethics approval under the National Mutual Acceptance scheme. Data will be routinely reported to participating sites describing performance against measures of agreed best practice and nationally to stakeholders including federal, state and territory departments of health. Local, regional and (bi)national benchmarks, augmented with online dashboard indicator reporting will enable local targeting of quality improvement efforts.

Curative therapy for rectal cancer.

Introduction: A comprehensive trimodality approach has become the standard of care for patients with locally advanced rectal cancer. However, the sequencing and duration of chemotherapy and chemoradiotherapy around surgery varies between clinical studies and geographical regions. Growing evidence is also mounting for strategies such as total neoadjuvant therapy and non-operative management for carefully selected patients.Areas covered: We provide a perspective review of the current evidence and controversies in the treatment of locally advanced rectal cancer including the recent updates from the 2020 ASCO annual conference.Expert opinion: With ongoing advances in the management of locally advanced rectal cancer, a multidisciplinary team approach is necessary as treatments could involve multiple approaches. Chemoradiotherapy whether short or long course followed by at least 3 months of systemic chemotherapy may be the preferred option to balance local and distant disease control. Albeit the choice of doublet or triplet chemotherapy is still controversial. As total neoadjuvant treatment becomes part of the standard of care in rectal cancer, modification of the surveillance schedule is needed to detect early recurrences which may be limited by resources and availability of services.

Patterns of care and outcomes for gastric and gastro-oesophageal junction cancer in an Australian population.

BACKGROUND: A single state-wide upper gastrointestinal (GI) cancer video-linked multidisciplinary team (MDT) meeting guides management and evidence-based care for all newly diagnosed upper GI cancer patients in South Australia. This study determined the patterns of care and outcomes for patients diagnosed with gastric and gastro-oesophageal junction (GOJ) cancers. METHODS: Patients diagnosed with gastric cancer and GOJ (Siewert III) cancer between June 2012 and June 2016 were included. Patient demographics, cancer stage, histology, diagnostic modalities and treatment data was analysed from a prospective database. Stage-specific survival outcomes were determined and analysed for each treatment modality. RESULTS: The study included 218 patients and at diagnosis 132 (61%) patients had stage I-III and 86 (39%) patients had stage IV disease. One hundred and ninety-five (89%) patients had gastric cancer and 23 (11%) had GOJ cancer (Siewert III). One hundred and nine (50%) patients underwent surgery, with 92% R0 resection rate. Forty-six patients received perioperative chemotherapy and 111 (51%) patients received palliative intent treatment. Median overall survival for stage II, III and IV cancers was 57.6 (95% CI 57.6-NR), 22.8 (95% CI 20.4-43.2), and 6.0 months (95% CI 4.8-8.4) respectively (p < 0.001). Median overall survival for patients who underwent perioperative chemotherapy and surgery was not reached as compared to 44.4 months (95% CI 28.8-NR) for patients who underwent surgery alone. CONCLUSION: Treatment outcomes for patients with gastric and GOJ cancer managed across South Australia met contemporary evidence-based practice. However, as most patients continue to present with late-stage disease, longer-term survival remains poor.

Epidemiology of neuroendocrine cancers in an Australian population.

OBJECTIVE: The aim was to explore incidence, mortality and case survivals for invasive neuroendocrine cancers in an Australian population and consider cancer control implications. METHODS: Directly age-standardised incidence and mortality rates were investigated from 1980 to 2006, plus disease-specific survivals. RESULTS: Annual incidence per 100,000 increased from 1.7 in 1980-1989 to 3.3 in 2000-2006. A corresponding mortality increase was not observed, although numbers of deaths were low, reducing statistical power. Increases in incidence affected both sexes and were more evident for female lung, large bowel (excluding appendix), and unknown primary site. Common sites were lung (25.9%), large bowel (23.3%) (40.9% were appendix), small intestine (20.6%), unknown primary (15.0%), pancreas (6.5%), and stomach (3.7%). Site distribution did not vary by sex (p = 0.260). Younger ages at diagnosis applied for lung (p = 0.002) and appendix (p < 0.001) and older ages for small intestine (p < 0.001) and unknown primary site (p < 0.001). Five-year survival was 68.5% for all sites combined, with secular increases (p < 0.001). After adjusting for age and diagnostic period, survivals were higher for appendix and lower for unknown primary site, pancreas, and colon (excluding appendix). CONCLUSIONS: Incidence rates are increasing. Research is needed into possible aetiological factors for lung and large-bowel sites, including tobacco smoking, and excess body weight and lack of exercise, respectively; and Crohn's disease as a possible precursor condition.

Cardiac angiosarcoma: A diagnostic and therapeutic challenge.

Cardiac angiosarcomas are a rare group of soft tissue sarcomas, characterized by aggressive local growth and early spread. Because this is an uncommon disease, there is currently no standard treatment approach. When localized, surgery appears to lead to the best outcomes, but this can be technically challenging and not always feasible. Upfront chemoradiotherapy provides an alternative that may shrink the tumor to enable definitive surgical resection. We report a case of primary cardiac angiosarcoma with a complete metabolic and pathological response after upfront chemoradiotherapy with paclitaxel, who then underwent surgery, as a potential treatment option for patients with this rare condition. .

A systematic scoping review of determinants of multidisciplinary cancer team access and decision-making in the management of older patients diagnosed with colorectal cancer.

Early diagnosis of colorectal cancer (CRC) and access to optimal treatment achieves optimal cancer outcomes. However, CRC survival inequalities persist with a lower survival rate for older patients (≥65 years). Although the reasons for poorer cancer survival in older people are complex, evidence suggests that these patients are less likely to receive best practice care as indicated by access to multidisciplinary team (MDT) care. Three electronic databases were systematically searched to examine factors that affect access to, and clinical decision-making, in the context of MDT care of older people with CRC. We included studies reporting empirical data relating to predictors for a patient's case being discussed at a MDT meeting and/or factors that impact treatment decision-making during the meeting. From 303 returned titles and abstracts, eighteen articles were reviewed. Eight studies specifically selected older patients, with eligibility criteria varying from ≥65 to ≥80 years. Five articles explored predictors of MDT access, with all articles identifying age as a negative, and advanced stage as a positive predictor of MDT discussion. Fourteen studies explored factors that influenced the MDT decision-making process, with older age and presence of comorbid disease negatively influencing treatment decisions (cases less often discussed and/or treatment not recommended). A few studies identified access to a MDT discussion as an independent predictor for CRC treatment. Access to the MDT process for older patients with a CRC diagnosis should be based on relevant geriatric domains rather than on chronological age alone, which is expected to allow more appropriate clinical decision-making and reduce treatment inequities for older patients with cancer.
