ABSTRACT

Neoantigens arise from mutations in cancer cells and are important targets of T cell-mediated anti-tumor immunity. Here, we report the first open-label, phase Ib clinical trial of a personalized neoantigen-based vaccine, NEO-PV-01, in combination with PD-1 blockade in patients with advanced melanoma, non-small cell lung cancer, or bladder cancer. This analysis of 82 patients demonstrated that the regimen was safe, with no treatment-related serious adverse events observed. De novo neoantigen-specific CD4+ and CD8+ T cell responses were observed post-vaccination in all of the patients. The vaccine-induced T cells had a cytotoxic phenotype and were capable of trafficking to the tumor and mediating cell killing. In addition, epitope spread to neoantigens not included in the vaccine was detected post-vaccination. These data support the safety and immunogenicity of this regimen in patients with advanced solid tumors (Clinicaltrials.gov: NCT02897765).

ABSTRACT

A quintessential setting for precision medicine, theranostics refers to a rapidly evolving field of medicine in which disease is diagnosed followed by treatment of disease-positive patients using tools for the therapy identical or similar to those used for the diagnosis. Against the backdrop of only-treat-when-visualized, the goal is a high therapeutic index with efficacy markedly surpassing toxicity. Oncology leads the way in theranostics innovation, where the approach has become possible with the identification of unique proteins and other factors selectively expressed in cancer versus healthy tissue, advances in imaging technology able to report these tissue factors, and major understanding of targeting chemicals and nanodevices together with methods to attach labels or warheads for imaging and therapy. Radiotheranostics-using radiopharmaceuticals-is becoming routine in patients with prostate cancer and neuroendocrine tumors who express the proteins PSMA (prostate-specific membrane antigen) and SSTR2 (somatostatin receptor 2), respectively, on their cancer. The palpable excitement in the field stems from the finding that a proportion of patients with large metastatic burden show complete and partial responses, and this outcome is catalyzing the search for more radiotheranostics approaches. Not every patient will benefit from radiotheranostics; but, for those who cross the target-detected line, the likelihood of response is very high.

ABSTRACT

While there is a great clinical need to understand the biology of metastatic cancer in order to treat it more effectively, research is hampered by limited sample availability. Research autopsy programmes can crucially advance the field through synchronous, extensive, and high-volume sample collection. However, it remains an underused strategy in translational research. Via an extensive questionnaire, we collected information on the study design, enrolment strategy, study conduct, sample and data management, and challenges and opportunities of research autopsy programmes in oncology worldwide. Fourteen programmes participated in this study. Eight programmes operated 24 h/7 days, resulting in a lower median postmortem interval (time between death and start of the autopsy, 4 h) compared with those operating during working hours (9 h). Most programmes (n = 10) succeeded in collecting all samples within a median of 12 h after death. A large number of tumour sites were sampled during each autopsy (median 15.5 per patient). The median number of samples collected per patient was 58, including different processing methods for tumour samples but also non-tumour tissues and liquid biopsies. Unique biological insights derived from these samples included metastatic progression, treatment resistance, disease heterogeneity, tumour dormancy, interactions with the tumour micro-environment, and tumour representation in liquid biopsies. Tumour patient-derived xenograft (PDX) or organoid (PDO) models were additionally established, allowing for drug discovery and treatment sensitivity assays. Apart from the opportunities and achievements, we also present the challenges related with postmortem sample collections and strategies to overcome them, based on the shared experience of these 14 programmes. Through this work, we hope to increase the transparency of postmortem tissue donation, to encourage and aid the creation of new programmes, and to foster collaborations on these unique sample collections. © 2024 The Authors.

ABSTRACT

During the COVID-19 pandemic recommendations were made to adapt cancer care. This population-based study aimed to investigate possible differences between the treatment of patients with metastatic cancer before and during the pandemic by comparing the initial treatments in five COVID-19 periods (weeks 1-12 2020: pre-COVID-19, weeks 12-20 2020: 1st peak, weeks 21-41 2020: recovery, weeks 42-53 2020: 2nd peak, weeks 1-20 2021: prolonged 2nd peak) with reference data from 2017 to 2019. The proportion of patients receiving different treatment modalities (chemotherapy, hormonal therapy, immunotherapy or targeted therapy, radiotherapy primary tumor, resection primary tumor, resection metastases) within 6 weeks of diagnosis and the time between diagnosis and first treatment were compared by period. In total, 74,208 patients were included. Overall, patients were more likely to receive treatments in the COVID-19 periods than in previous years. This mainly holds for hormone therapy, immunotherapy or targeted therapy and resection of metastases. Lower odds were observed for resection of the primary tumor during the recovery period (OR 0.87; 95% CI 0.77-0.99) and for radiotherapy on the primary tumor during the prolonged 2nd peak (OR 0.84; 95% CI 0.72-0.98). The time from diagnosis to the start of first treatment was shorter, mainly during the 1st peak (average 5 days, p < .001). These findings show that during the first 1.5 years of the COVID-19 pandemic, there were only minor changes in the initial treatment of metastatic cancer. Remarkably, time from diagnosis to first treatment was shorter. Overall, the results suggest continuity of care for patients with metastatic cancer during the pandemic.

ABSTRACT

Identifying the primary site of origin of metastatic cancer is vital for guiding treatment decisions, especially for patients with cancer of unknown primary (CUP). Despite advanced diagnostic techniques, CUP remains difficult to pinpoint and is responsible for a considerable number of cancer-related fatalities. Understanding its origin is crucial for effective management and potentially improving patient outcomes. This study introduces a machine learning framework, ONCOfind-AI, that leverages transcriptome-based gene set features to enhance the accuracy of predicting the origin of metastatic cancers. We demonstrate its potential to facilitate the integration of RNA sequencing and microarray data by using gene set scores for characterization of transcriptome profiles generated from different platforms. Integrating data from different platforms resulted in improved accuracy of machine learning models for predicting cancer origins. We validated our method using external data from clinical samples collected through the Kangbuk Samsung Medical Center and Gene Expression Omnibus. The external validation results demonstrate a top-1 accuracy ranging from 0.80 to 0.86, with a top-2 accuracy of 0.90. This study highlights that incorporating biological knowledge through curated gene sets can help to merge gene expression data from different platforms, thereby enhancing the compatibility needed to develop more effective machine learning prediction models.

ABSTRACT

BACKGROUND: Feasibility of exercise in patients with metastatic cancer is still a challenge. This study aimed to determine the feasibility and preliminary efficacy of an exercise intervention based on a patient-preferred delivery mode in patients affected by metastatic cancer. MATERIALS AND METHODS: Forty-four patients with a confirmed diagnosis of metastatic cancer were recruited in a 3-month exercise program. Whereas the exercise program consisted of aerobic and resistance activities performed twice a week, the participants may choose the mode of delivery: home based, personal training, or group based. The primary endpoint was the feasibility, defined by recruitment rate, attendance, adherence, dropout rate, tolerability (comparing the session RPE with the target RPE), and safety (using the Common Terminology Criteria for Adverse Events, version 5.0). Secondary endpoints included cardiorespiratory fitness (six minutes walking test), muscle strength (handgrip strength test and isometric leg press test), flexibility (the back scratch and chair sit and reach tests), anthropometric parameters (body mass index and waist-hip ratio), quality of life (EORTC QLQ C-30 questionnaire), and amount of physical exercise (Godin's Shepard Leisure Time Exercise Questionnaire). Descriptive statistics, Student t test, and Wilcoxon signed rank test were used to analyze data. RESULTS: The study recruitment rate was 81%. Out of 44 recruited patients, 28 chose the personal training program, 16 chose the home-based program, and none chose the group-based program. Nine dropouts occurred (20%), 6 in the personal training program, and 3 in the home-based intervention. The median attendance rate was 92%, adherence was 88%, tolerability was 100%, and 9 nonsevere adverse events were registered during the exercise sessions. An increase in cardiorespiratory fitness (P < .001) and flexibility (P = .011 for chair sit and reach; P = .040 for back scratch) was observed at the end of the intervention, while no changes in anthropometric values and muscle strength were detected. Different quality-of-life domains were improved following the intervention, including physical (P = .002), emotional (P < .001), and role functioning (P = .018), fatigue (P = .030), and appetite loss (P = .005). CONCLUSION: A 3-month exercise program based on a patient-preferred delivery mode is feasible in patients with metastatic cancer and may improve physical function and quality of life. TRIAL REGISTRATION: NCT04226508.

ABSTRACT

BACKGROUND: We aim to provide survival scenario estimates for patients with advanced melanoma starting targeted therapies and immunotherapies. MATERIALS AND METHODS: We sought randomized trials of targeted therapies and immunotherapies for advanced melanoma and recorded the following percentiles (represented survival scenario) from each overall survival (OS) curve: 90th (worst-case), 75th (lower-typical), 50th (median), 25th (upper-typical), and 10th (best-case). We tested whether these scenarios can be estimated for each OS curve by multiplying its median by 4 multiples: 0.25 (worst-case), 0.5 (lower-typical), 2 (upper-typical), and 3 (best-case). RESULTS: We identified 15 trials with 8025 patients. For first-line combination targeted therapy treatment groups, the median (interquartile range, IQR) in months for each percentile was: 90th, 6.2 (6.0-6.5); 75th, 11.3 (11.3-11.4); and median, 24.4 (23.5-25.3). For the first-line combination immunotherapy treatment group, the percentiles in months were: 90th, 3.9 (2.8-4.5); 75th, 13.4 (10.1-15.4), median 73 (not applicable). In targeted therapy groups, simple multiples of the median OS were accurate for estimating the 90th percentile in 80%; 75th percentile in 40%; 25th percentile in 100%. In immunotherapy groups, these multiples were accurate at 0% for the 90th percentile, and 43% for the 75th percentile. The 90th percentile (worst-case scenario) was better estimated as 1/6× median OS, and the 75th percentile (lower-typical) as 1/3× median OS. CONCLUSIONS: Simple multiples of the median OS are a useful framework to estimate scenarios for survival for patients receiving targeted therapies, not immunotherapy. Longer follow-up is required to estimate upper-typical and best-case scenarios.

ABSTRACT

BACKGROUND: Immunotherapy brings new hope to patients with advanced gastric cancer. However, liver metastases can reduce the efficacy of immunotherapy in patients. Tumor-associated macrophages (TAMs) may be the cause of this reduction in efficacy. SPP1 + TAMs are considered to have immunosuppressive properties. We aimed to investigate the involvement of SPP1 + TAMs in the metastasis of gastric cancer. METHODS: The single-cell transcriptome was combined with batched BULK datasets for analysis. Animal models were used to verify the analysis results. RESULTS: We reveal the interaction of SPP1 + TAMs with CD8 + exhausted T cells in metastatic cancer. Among these interactions, GDF15-TGFBR2 may play a key immunosuppressive role. We constructed an LR score to quantify interactions based on ligands and receptors. The LR score is highly correlated with various immune features and clinical molecular subtypes. The LR score may also guide the prediction of the efficacy of immunotherapy and prognosis. CONCLUSIONS: The crosstalk between SPP1 + TAMs and CD8 + exhausted T cells plays a key immunosuppressive role in the gastric metastatic cancer microenvironment.

ABSTRACT

BACKGROUND: Few studies have focused on palliative surgery in patients with advanced gastroesophageal junction (GEJ) or gastric cancer. We sought to evaluate clinical observational outcomes following palliative surgery in this population. PATIENTS AND METHODS: Patients with GEJ or gastric cancer who underwent palliative surgery (1/2010-11/2022) were identified. The primary outcomes were symptom improvement, ability to tolerate an oral diet, discharge to home, 30 "good days" without hospitalization, and receipt of systemic treatment. Postoperative outcomes and survival were secondarily evaluated. RESULTS: Among 93 patients, the median age was 59 (IQR 47-68) years, and the median Eastern Cooperative Oncology Group Performance Status (ECOG-PS) was 1 (range 0-3). The most frequent indication for palliative surgery was primary tumor obstruction [75 (81%) patients]. The most common procedures were feeding tube placement in 60 (65%) and intestinal bypass in 15 (16%) patients. A total of 75 (81%) patients experienced symptom improvement. Of these, 19 (25%) developed recurrent and 49 (65%) developed new symptoms. ECOG-PS was significantly associated with symptom-free time. Among those who underwent a bypass, resection, or ostomy creation for malignant obstruction, 16 (80%) tolerated an oral diet. Postoperatively, 87 (94%) were discharged home, 72 (77%) had 30 good days, and 64 (69%) received systemic treatment. Postoperative complications occurred in 35 (38%) patients, and 7 (8%) died within 30 days. The median survival time was 7.7 (95% CI 6.4-10.40) months. CONCLUSIONS: Patients with incurable GEJ or gastric cancer can benefit from palliative surgery. Prognosis and performance status should inform goals-of-care discussions and patient selection for surgical palliation.

ABSTRACT

PURPOSE: Fluorescence imaging-guided surgery has been used in oncology. However, for tiny tumors, the current imaging probes are still difficult to achieve high-contrast imaging, leading to incomplete resection. In this study, we achieved precise surgical resection of tiny metastatic cancers by constructing an engineering erythrocyte membrane-camouflaged bioprobe (AR-M@HMSN@P). METHODS: AR-M@HMSN@P combined the properties of aggregation-induced emission luminogens (AIEgens) named PF3-PPh3 (P), with functional erythrocyte membrane modified by a modular peptide (AR). Interestingly, AR was composed of an asymmetric tripodal pentapeptide scaffold (GGKGG) with three appended modulars: KPSSPPEE (A6) peptide, RRRR (R4) peptide and cholesterol. To verify the specificity of the probe in vitro, SKOV3 cells with overexpression of CD44 were used as the positive group, and HLF cells with low expression of CD44 were devoted as the control group. The AR-M@HMSN@P fluorescence imaging was utilized to provide surgical guidance for the removal of micro-metastatic lesions. RESULTS: In vivo, the clearance of AR-M@HMSN@P by the immune system was reduced due to the natural properties inherited from erythrocytes. Meanwhile, the A6 peptide on AR-M@HMSN@P was able to specifically target CD44 on ovarian cancer cells, and the electrostatic attraction between the R4 peptide and the cell membrane enhanced the firmness of this targeting. Benefiting from these multiple effects, AR-M@HMSN@P achieved ultra-precise tumor imaging with a signal-to-noise ratio (SNR) of 15.2, making it possible to surgical resection of tumors < 1 mm by imaging guidance. CONCLUSION: We have successfully designed an engineered fluorescent imaging bioprobe (AR-M@HMSN@P), which can target CD44-overexpressing ovarian cancers for precise imaging and guide the resection of minor tumors. Notably, this work holds significant promise for developing biomimetic probes for clinical imaging-guided precision cancer surgery by exploiting their externally specified functional modifications.

ABSTRACT

OBJECTIVE: Patients with advanced cancer who parent minor children report parenting concerns and increased psychological distress. This cross-sectional study seeks to understand parenting-related issues in patients and spousal caregivers from a relationship perspective. METHODS: Patients with a metastatic solid malignancy and their spouses independently completed cross-sectional assessments of psychological distress (Hospital Anxiety and Depression Scale), parenting concerns (Parenting Concern Questionnaire) and efficacy (Cancer-Related Parenting Self-Efficacy Scale), and relationship measures (DAS-7, Couples' Illness Communication Scale, and Family Relationship Index). RESULTS: Of the 51 patients (57% female, 49% NHW, mean age 42 years) and spouses (43% female, 43% NHW, mean age of 42 years), approximately 50% couples endorsed psychological distress and were at risk for family dysfunction. Spouses reported significantly higher levels of parenting-related concerns (t = -2.0, p < 0.05) and anxiety (t = -2.8, p < 0.001) than patients. Parenting concerns were significantly associated with illness communication (r = -0.56, p < 0.001) and family function (r = -0.38, p < 0.001). Although the expected interactions between parenting concerns and relationship variables (i.e., illness communication, dyadic adjustment, and family function) were significant for depressive symptoms at p < 0.05, the associations were not in the expected direction. Relationship function buffered against depressive symptoms for those with low rather than high parenting concerns. CONCLUSIONS: Not only patients but also spouses report cancer-related parenting concerns. The associations between parenting concerns and distress were stronger for spouses than patients. Dual caregiving appears to be a particularly stressful role. Because relationship function was associated with parenting concerns, we suggest that parent support programs that are couple-based and include both parenting-specific and relationship-specific content may be most effective in reducing distress for this vulnerable population.

ABSTRACT

BACKGROUND: Schizophrenia and advanced cancer are complex conditions that impact life expectancy. This study aimed to examine the receipt of specialized palliative care (SPC) in patients with metastatic cancer and a coexisting diagnosis of psychosis compared to patients with cancer only. Secondary objectives included analyzing differences in emergency visits and place of death in relation to receipt of SPC. PATIENTS AND METHODS: This retrospective, observational registry study utilized health care consumption data from the Stockholm Regional Council. We included 23,056 patients aged >18 years who died between 2015 and 2021 with a diagnosis of metastatic cancer, hematologic malignancy, or malignant brain tumor in the Stockholm Gotland region. Among them, 320 patients had a concomitant diagnosis of psychosis. RESULTS: Patients with cancer and psychosis were less likely to receive SPC compared to patients with cancer only (61% vs. 74%, p < 0.001). Additionally, they were, on average, four and a half years younger at the time of death (68.5 years vs. 73.1 years, p < 0.0001), more likely to reside in nursing homes (25% vs. 11%, p < 0.0001), and had a higher prevalence of low area-based socioeconomic status (46% vs. 32%, p < 0.0001). Receipt of SPC was associated with reduced frequency of emergency visits and a higher probability of place of death to be at home or in a care facility outside the acute hospital. CONCLUSIONS: Patients with a coexisting diagnosis of psychosis and metastatic cancer have a lower probability of receiving SPC. Receipt of specialized palliative care was associated with reduced number of unplanned emergency visits and a lower risk for death at an acute hospital. Efforts are needed to ensure equitable provision of SPC for patients with cancer and psychosis.

ABSTRACT

PURPOSE: This study describes financial toxicity (FT) reported by people with metastatic cancer, characteristics associated with FT, and associations between FT and compensatory strategies to offset costs. METHODS: Cancer Support Community's Cancer Experience Registry data was used to identify respondents with a solid tumor metastatic cancer who completed the Functional Assessment of Chronic Illness Therapy COmprehensive Score for Financial Toxicity (FACIT-COST) measure. Multivariable logistic regression analyses examined associations between respondent characteristics and FT, and FT and postponing medical visits, nonadherence to medications, and postponing supportive and/or psychosocial care. RESULTS: 484 individuals were included in the analysis; the most common cancers included metastatic breast (31%), lung (13%), gynecologic (10%), and colorectal (9%). Approximately half of participants (50.2%) reported some degree of FT. Those who were non-Hispanic White, Hispanic, or multiple races (compared to non-Hispanic Black), and who reported lower income, less education, and being less than one year since their cancer diagnosis had greater odds of reporting FT. Individuals with any level of FT were also more likely to report postponing medical visits (Adjusted Odds Ratio [OR] 2.58; 95% Confidence Interval [CI] 1.45-4.58), suboptimal medication adherence (Adjusted OR 5.05; 95% CI 2.77-9.20) and postponing supportive care and/or psychosocial support services (Adjusted OR 4.16; 95% CI 2.53-6.85) compared to those without FT. CONCLUSIONS: With increases in the number of people living longer with metastatic cancer and the rising costs of therapy, there will continue to be a need to systematically screen and intervene to prevent and mitigate FT for these survivors.

ABSTRACT

PURPOSE: The time toxicity of anticancer therapy, defined as days spent with healthcare contact during treatment, represents a critical but understudied outcome. This study aims to quantify time toxicity among older patients with cancer receiving palliative systemic treatment. METHODS: All patients aged ≥ 65 years with metastatic cancer receiving cytotoxic chemotherapy, immunotherapy, or targeted therapy at a single center in Mexico were selected from a prospective patient navigation cohort. Patients completed a baseline assessment, including the G8 screening and quality of life measures. Physical healthcare contact days within the first 6 months were extracted from medical records and divided by days alive during the same period. Beta regression models were used to identify predictors of time toxicity. RESULTS: We identified 158 older patients (median age 71 years); 86% received cytotoxic chemotherapy. Seventy-three percent had an impaired G8 score and were considered vulnerable/frail. Six-month overall survival was 74%. Within the first 6 months, patients spent a mean of 21% (95% confidence interval (CI) 19-23%) of days with healthcare contact. Concurrent radiotherapy (odds ratio (OR) 1.55; 95%CI 1.21-1.97), cytotoxic chemotherapy versus targeted therapy (OR 1.64; 95%CI 1.13-2.37), and an impaired G8 (OR 1.27; 95%CI 1.01-1.60) were associated with increased time toxicity. CONCLUSION: Older adults with metastatic cancer spend 1 in 5 days with healthcare contact during treatment, with a higher burden of time toxicity for patients receiving radiotherapy or cytotoxic chemotherapy and those with potential frailty. These findings underscore the importance of informing patients about their expected healthcare contact days within the context of a limited life expectancy.

ABSTRACT

People with advanced cancer and cachexia experience significant body weight loss, adversely impacting physical function and quality of life (QOL). Effective, evidence-based treatments for cancer cachexia are lacking, leaving patients with unmet needs. Exercise holds promise to improve patient QOL. However, information on patients' experiences of exercise, including their ability to cope with structured exercise, is limited. PURPOSE: To explore patient experiences completing a structured, supervised exercise program for people with cachexia due to advanced cancer. METHODS: Semi-structured interviews were conducted with participants enrolled in a phase II feasibility, randomized controlled trial to explore their experiences of an 8-week virtually supervised exercise program delivered via videoconference technology. Interviews were analysed using reflexive thematic analysis. RESULTS: Seventeen participants completed interviews (female n = 9, 53%). Main interview themes included the following: (1) Deciding to exercise involves balancing concerns and expectations, (2) the exercise program is a positive experience, and (3) moving forward after the exercise program. While some participants initially held doubts about their physical capabilities and exercise safety, most wanted to exercise to enhance their wellbeing. Participants described the exercise program as a positive experience, offering diverse benefits. Some would have preferred in-person exercise, but all agreed the virtual format increased convenience. Participants emphasized the need to recommend the program to others in similar circumstances. They underscored the necessity and desire for ongoing support to sustain their new exercise habits. CONCLUSION: Based on patient experiences, virtually supervised exercise programming appears to be feasible and meaningful to people with advanced cancer and cachexia.

ABSTRACT

BACKGROUND: Improving quality of life (QOL) in advanced and metastatic cancer is a priority with increasing survivorship. This systematic review synthesizes psychosocial and behavioral interventions incorporating culture with the goal of examining their benefit for understudied and medically underserved populations with advanced and metastatic cancer. METHOD: Reports were systematically screened for (1) a focus on advanced and metastatic cancer survivors, (2) psychosocial or behavioral intervention intended to improve QOL, (3) evidence of incorporating the culture(s) of understudied/underserved populations, and (4) availability in English. Bias was evaluated using the JBI Critical Appraisal Checklist and the Methodological index for non-randomized studies. Qualitative synthesis and quantitative meta-analyses were completed. RESULTS: Eighty-six reports containing 5981 participants' data were examined. Qualitative synthesis of 23 studies identified four overarching themes relevant for incorporating culture in interventions. Meta-analysis of 19 RCTs and 4 quasi-experimental studies containing considerable heterogeneity indicated greater improvements in QOL (g = 0.84), eudaimonic well-being (g = 0.53), distress (g = -0.49), and anxiety (g = -0.37) for main intervention conditions compared to controls. Meta-analysis of 10 single-arm trials containing minimal to moderate heterogeneity found benefit for anxiety (g = -0.54), physical symptoms (g = -0.39), and depression (g = -0.38). CONCLUSION: Psychosocial and behavioral interventions with cultural incorporation appear beneficial for improving QOL-related outcomes in advanced and metastatic cancer. Studies incorporating culture in psychosocial or behavioral interventions offer noteworthy insight and suggestions for future efforts such as attending to deep cultural structure.

BACKGROUND: This study aimed to assess the health-related quality of life (HRQOL) (physical, functional, emotional, social, spiritual) and psychological (anxiety and depression) well-being and their associations with patient characteristics among patients with metastatic cancer in Bangladesh. METHODS: A convenience sample of 386 Bangladeshi patients with stage IV solid cancers was recruited from a palliative care outpatient department and an inpatient palliative center. Dependent variables included the physical, functional, emotional, social, and overall scores of the Functional Assessment of Cancer Therapy-General (FACT-G) scale, the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being (FACIT-SP) scale, the anxiety, depression, and overall scores of the Hospital Anxiety and Depression (HADS) scale. Linear regressions examined the association between dependent variables and patient characteristics. RESULTS: A substantial proportion of Bangladeshi patients reported anxiety (59% of outpatients and 55% of inpatients) and depression (60% of outpatients and 73% of inpatients) symptoms. Generally, greater financial difficulty and symptom burden scores were associated with worse health outcomes. Older patients reported poorer functional and spiritual well-being but better anxiety scores. Females reported worse anxiety and depressive symptoms and physical well-being but better spiritual outcomes. CONCLUSIONS: Additional efforts must be directed at improving the HRQOL of patients with metastatic cancer in Bangladesh. Furthermore, assistance should be made more accessible to vulnerable groups, including women, the elderly, and those with financial difficulty.

ABSTRACT

Background and Objectives: Rectal cancer is considered cured if no recurrence is found during the 5-year follow-up period after treatment. After this period, patients often believe that the cancer is completely eradicated. However, in modern society, where lifespans have become longer, it is important to recognize that metastatic cancer may occur long after the initial treatment has concluded. This highlights the necessity of continued vigilance and the long-term follow-up of cancer survivors. Case report: We present a case of metastatic cancer of the coccyx in an 87-year-old female patient. This patient had undergone successful surgery and treatment for rectal cancer 10 years prior. She was considered cured after the standard 5-year follow-up period as she showed no signs of recurrence. The patient presented with simple coccygeal pain as the main complaint, without any other accompanying symptoms such as weight loss, fever, or changes in bowel habits, typically associated with cancer recurrence. During the clinical evaluation, irregularities in the bone cortex were detected while performing a nerve block using ultrasound. Given these findings, further diagnostic evaluations were performed. Advanced imaging techniques including MRI and CT scans led to a diagnosis of coccygeal metastasis. Conclusions: While the 5-year mark post-treatment is a significant milestone for rectal cancer patients, it does not guarantee the absolute eradication of the disease. Long-term monitoring and a thorough evaluation of new symptoms are essential for the early detection and management of late metastatic recurrences. This approach ensures that patients receive timely and appropriate care, potentially improving outcomes and quality of life.

ABSTRACT

BACKGROUND: Immunotherapy (IO) has become a standard of care for treating various types of metastatic cancers and has significantly improved clinical outcome. With the exception of metastatic melanoma in complete response for which treatment can be stopped at 6 months, these treatments are currently administered until either disease progression for some IO, 2 years for others, or unacceptable toxicity. However, a growing number of studies are reporting maintenance of response despite discontinuation of therapy. There is currently no evidence of a dose effect of IO in pharmacokinetic studies. Maintaining efficacy despite a reduction in treatment intensity by decreasing the frequency of administration in patients with highly selected metastatic cancer, is the hypothesis evaluated in the MOIO study. METHOD/DESIGN: This non-inferiority, randomized phase III study aims to compare the standard regimen to a 3 monthly regimen of variousIO drugs in adult patients with metastatic cancer in partial (PR) or complete response (CR) after 6 months of standard IO dosing (except melanoma in CR). This is a French national study conducted in 36 centers. The main objective is to demonstrate that the efficacy of a three-monthly administration is not unacceptably less efficacious than a standard administration. Secondary objectives are cost-effectiveness, quality of life (QOL), anxiety, fear of relapse, response rate, overall survival and toxicity. After 6 months of standard IO, patients with partial or complete response will be randomized 1:1 between standard IO or a reduced intensity dose of IO, administered every 3 months. The randomization will be stratified on therapy line,, tumor type, IO type and response status. The primary endpoint is the hazard ratio of progression-free survival. With a planned study duration of 6 years, including 36 months enrolment time, 646 patients are planned to demonstrate with a statistical level of evidence of 5% that the reduced IO regimen is non-inferior to the standard IO regimen, with a relative non-inferiority margin set at 1.3. DISCUSSION: Should the hypothesis of non-inferiority with an IO reduced dose intensity be validated, alternate scheduling could preserve efficacy while being cost-effective and allowing a reduction of the toxicity, with an increase in patient's QOL. TRIAL REGISTRATION: NCT05078047.

ABSTRACT

BACKGROUND: The goal of therapy for many patients with advanced stage malignancies, including those with metastatic gastric and esophageal cancers, is to extend overall survival while also maintaining quality of life. After weighing the risks and benefits of treatment with palliative chemotherapy (PC) with non-curative intent, many patients decide to pursue treatment. It is known that a subset of patients who are treated with PC experience significant side effects without clinically significant survival benefits from PC. METHODS: We use data from 150 patients with stage-IV gastric and esophageal cancers to train machine learning models that predict whether a patient with stage-IV gastric or esophageal cancers would benefit from PC, in terms of increased survival duration, at very early stages of the treatment. RESULTS: Our findings show that machine learning can predict with high accuracy whether a patient will benefit from PC at the time of diagnosis. More accurate predictions can be obtained after only two cycles of PC (i.e., about 4 weeks after diagnosis). The results from this study are promising with regard to potential improvements in quality of life for patients near the end of life and a potential overall survival benefit by optimizing systemic therapy earlier in the treatment course of patients.
