An abnormal baseline geriatric 8 screening tool score strongly associates with increased long-term healthcare utilization in older patients with cancer

 A recent retrospective analysis conducted in the Department of General Medical Oncology at University Hospitals Leuven in Belgium indicates that "in the first 3 months after diagnosis of cancer in older patients, the healthcare utilization peaked, typically related to active cancer treatment, and then decreased in the time thereafter."  Healthcare utilization consisted of hospital admission, length of stay, visits to the emergency department, days in intensive care, appoints with general practitioners, home care, and transfers to nursing homes.  According to Professor Hans Wildiers, (General Medical Oncology, University Hospital Leuven, Belgium) "to optimize cancer treatment for older patients, it is important to identify frailty and underlying geriatric conditions at cancer diagnosis."

New studies presented at 2023 ASCO annual meeting ties loneliness and major financial event to cancer diagnoses and higher mortality risk

 New studies unveiled at the 2023 annual meeting of the American Society of Clinical Oncology (ASCO), held in Chicago from June 2-6, 2023, indicate loneliness and experiencing a major financial event as direct correlations to a cancer diagnosis and higher mortality risk.  

Led by Jingxuan Zhao, senior associate scientist of health services research at the American Cancer Society, cancer survivors 50 years and older reported "elevated loneliness scores [and] had higher hazard ratios, indicating higher mortality risks."  These findings occurred even after adjusting for sociodemographic characteristics, leading to strong recommendations to implement programs to screen for loneliness among cancer survivors and provide social support. 

An additional study unveiled at the ASCO annual meeting indicates that 1/3 of cancer patients experienced a major adverse financial event (AFE), such as bankruptcy, lien, or eviction, prior to being diagnosed with cancer, and were subsequently diagnosed at a later cancer stage.  Of the 101,649 patients studied, 32.6% had a major AFE before being diagnosed, most commonly among non-Hispanic Black, unmarried, and low-income patients.  However, "even 27% of patients in the highest income group had an AFE prior to diagnosis."

Use of immune checkpoint inhibitors safe and effective in cancer patients with HIV and on antiretroviral therapy

 A recently conducted retrospective study by the Cancer Therapy Using Checkpoint Inhibitors in People Living with HIV-International (CATCH0IT) Consortium determined that immune checkpoint inhibitors were found to be safe and had "differential activity across tumour types."  CATCH-IT enrolled 390 cancer patients with HIV into their cohort, "who received anti-PD-1 or anto-PD-L1 therapies and evaluated the safety and activity." This cohort was unique, as patients with HIV are at higher risk for developing cancer, due to dysfunctional immune systems.   The 3 most common cancer identified in the cohort included non-small-cell lung cancer (28%), hepatocellular carcinoma (11%), and head and neck squamous cell carcinoma (10%).  While the study authors acknowledged the relatively small sample size for this study, the results do support "the growing body of evidence [among] the use of ICIs [in] patients with HIV to enhance their inclusion in clinical studies."

New study shows mortality rates for most cancers decreasing globally, except liver cancer in men and lung cancer in women increasing

A new study conducted by the American Cancer Society has found a downward trend in mortality rates for major cancers worldwide, with the exception of liver cancer in men and lung cancer in women.  According to Dr. Ahmedin Jemal, senior author of the study, "these findings reinforce the importance of strengthening the health systems not only in resource-limited countries but also in high-income countries across the world for broad and equitable implementation of known cancer prevention and control interventions."   24 countries in the study reported higher mortality rates from lung cancer in women, with the highest increase noted in Spain (4.3%), Uruguay (3.7%), and Greece (3.2%).  For men, highest increases in liver cancer were found in Ireland (5.8%), Norway (5.3%), and Malta (4.8%), increases which have been attributed to hepatitis C infection, and nonviral etiology, including obesity, diabetes, and heavy alcohol consumption.

Patients diagnosed with cancer during pregnancy may have increased risk of mortality

 A recently completed population-based cohort study at the University of Calgary's Department of Obstetrics and Gynaecology indicates that patients diagnosed with cancer while pregnant "had elevated mortality, but this association was not consistent across all cancer sites."  According to Dr. Amy Metcalfe and colleagues, cancer is the 2nd leading cause of death in premenopausal women, attributable to "increases in delayed childbearing, , improvements in diagnostic testing, awareness of genetic risk factors and subsequent screening, and expansion of population-based screening programs."  Further, only 25% of cancers are diagnosed during pregnancy; 75% of diagnoses occur in the postpartum period.

Similarity of molecular portraits in synchronous bilateral breast cancers could be influenced by common environmental factors

 A recent study conducted within the Translational Research Department, Institut Curie, Universite de Paris, found that in breast cancer patients, "immune infiltration was not determined purely by local tumour microenvironment properties, but was different according to the subtype of the contralateral tumour."  The study further unveiled that 5% of patients with bilateral breast cancers carry BRCA1 or BRCA2 mutations; from the 17575 patients listed in the Institut Curie clinical databases, only 2.3% (404) patients had synchronous bilateral breast cancers.

study of Hodgkin lymphoma survivors suggests a dose-response association of colorectal cancer risk with subdiaphragmatic radiotherapy

 Findings from a case-control study of Hodgkin lymphoma survivors after a 5-year period found a "dose-response association between radiotherapy and colorectal cancer risk, and modification of this association by procarbazine."  Study authors also indicated that Hodgkin lymphoma survivors have a 2.8 times higher rate of a colorectal cancer diagnosis, a rate that remains at this increased level for over 40 years.  While these results are specific to a 5-year period (patients treated more recently would experience lower radiotherapy and chemotherapy doses), "an understanding of the dose-response relationship is needed to quantify and estimate the risk of secondary cancers based on individual treatment exposures."

Large genomic analysis identifies persistent tumour mutational burden associated with immunotherapy response

Findings from a recently completed genomic analysis published in Nature Medicine indicates that "a high persistent TMB [tumour mutational burden], a biologically relevant measure of tumour foreignness within the overall TMB, represents an 'uneditable' target set for adaptive immune responses and may function as an intrinsic driver of sustained immunologic tumour control that cannot be readily bypassed by neoantigen loss via chromosomal deletions during cancer evolution."  Following an extensive evaluation of mutations across 31 tumour types amongst 9,242 patients, along with 8 patient cohorts (total of 524 patients) diagnosed with non-small-cell lung cancer, melanoma, mesothelioma, and head and neck cancer patients, the study team discovered that "mutations in single-copy regions and those present in multiple copies per cell constitute a pTMB...linked with response to immune checkpoint blockade.

Prognostic role of ctDNA in patients with surgically resectable colorectal cancer

 Results from GALAXY, part of the CIRCULATE study from Japan, analyzing circulating tumour DNA (ctDNA) was recently published in Nature Medicine.  Investigators from GALAXY demonstrated that "postsurgical ctDNA status is a most significant prognostic biomarker than the currently used high-risk clinicopathological features in resectable colorectal cancer and can potentially be predictive of adjuvant chemotherapy benefit."  The study authors thus believe that incorporating postsurgical ctDNA into TNM staging criteria can be further developed as a result of findings from GALAXY.

Suicide risk higher among individuals with cancer

 A new study conducted by researchers at the American Cancer Society (ACS) indicates that "the risk for suicide of individuals diagnosed with cancer...is 26% higher compared with the general population."  While the study explains that additional characteristics, including geographic, racial/ethnic, and socioeconomic also play contributing roles to this statistic, Dr. Xuesong Han, senior study author explains that joint efforts by local and national governments are needed to ensure insurance coverage for psycho-oncological and psychosocial issues, as well as "development of appropriate clinical guidelines for suicide risk screening and inclusion of suicide prevention in survivorship care plans."
