Update on thymic epithelial tumors: a narrative review.

Background and Objective: Thymoma, thymic carcinoma and thymic neuroendocrine tumors originate from the epithelial cells of the thymus and account for the thymic epithelial tumors (TETs). Although TETs are uncommon, they are the most frequent tumor type in the anterior mediastinum. Multidisciplinary approach is essential for their correct management. The aim of the present review is to summarize the update management for TETs. Methods: For this review, we searched in Excerpta Medica database (EMBASE) and MEDLINE until 6 September 2023. The terms used in the search included thymoma, thymic carcinoma, thymic epithelial tumors, management, immunotherapy, multiple tyrosine kinases inhibitors. Key Content and Findings: The therapeutic approach is based on histology and tumor stage and may involve surgery with or without neoadjuvant or adjuvant treatment. In the metastatic setting, platinum-based chemotherapy is the standard of care and patients who do not respond to first-line treatment have limited treatment options mainly because of the poor efficacy shown in subsequent lines of therapy. Conclusions: Future research should focus on identifying predictive biomarkers for patients with TETs, and should implement multicenter collaborations and appropriate clinical trials tailored for rare tumor types. Immune check point inhibitors, mammalian target of rapamycin (mTOR) and antiangiogenic multikinase inhibitors have also been studied in this clinical setting.

Systemic Inflammation Response Index and weight loss as prognostic factors in metastatic pancreatic cancer: A concept study from the PANTHEIA-SEOM trial.

BACKGROUND: The prognostic value of the Systemic Inflammation Response Index (SIRI) in advanced pancreatic cancer is recognized, but its correlation with patients´ nutritional status and outcomes remains unexplored. AIM: To study the prognostic significance of SIRI and weight loss in metastatic pancreatic cancer. METHODS: The PANTHEIA-Spanish Society of Medical Oncology (SEOM) study is a multicentric (16 Spanish hospitals), observational, longitudinal, non-interventional initiative, promoted by the SEOM Real World-Evidence work group. This pilot study sought to analyze the association between weight loss and inflammatory status as defined by SIRI. The cohort stems from a proof-of-concept pilot study conducted at one of the coordinating centers. Patients with pathologically confirmed metastatic pancreatic adenocarcinoma, treated from January 2020 to January 2023, were included. The index was calculated using the product of neutrophil and monocyte counts, divided by lymphocyte counts, obtained within 15 days before initiation chemotherapy. This study evaluated associations between overall survival (OS), SIRI and weight loss. RESULTS: A total of 50 patients were included. 66% of these patients were male and the median age was 66 years. Metastasis sites: 36% liver, 12% peritoneal carcinomatosis, 10% lung, and 42% multiple locations. Regarding the first line palliative chemotherapy treatments: 50% received gemcitabine plus nab-paclitaxel; 28%, modified fluorouracil, leucovorin, irinotecan and oxaliplatin, and 16% were administered gemcitabine. 42% had a weight loss > 5% in the three months (mo) preceding diagnosis. 21 patients with a SIRI ≥ 2.3 × 103/L exhibited a trend towards a lower median OS compared to those with a SIRI < 2.3 × 103/L (4 vs 18 mo; P < 0.000). Among 21 patients with > 5% weight loss before diagnosis, the median OS was 6 mo, in contrast to 19 mo for those who did not experience such weight loss (P = 0.003). Patients with a weight loss > 5% showed higher SIRI levels. This difference was statistically significant (P < 0.000). For patients with a SIRI < 2.3 × 103/L, those who did not lose > 5% of their weight had an OS of 20 mo, compared to 11 mo for those who did (P < 0.001). No association was found between carbohydrate antigen 19-9 levels ≥ 1000 U/mL and weight loss. CONCLUSION: A higher SIRI was correlated with decreased survival rates in patients with metastatic pancreatic cancer and associated with weight loss. An elevated SIRI is suggested as a predictor of survival, emphasizing the need for prospective validation in the upcoming PANTHEIA-SEOM study.

Validation of the CoVID-TE model as a tool to predict thrombosis, bleeding, and mortality in the oncology patient with Sars-Cov-2 infection: a study by the SEOM cancer and thrombosis group

Purpose The CoVID-TE model was developed with the aim of predicting venous thrombotic events (VTE) in cancer patients with Sars-Cov-2 infection. Moreover, it was capable of predicting hemorrhage and mortality 30 days following infection diagnosis. The model is pending validation. Methods/patients Multicenter retrospective study (10 centers). Adult patients with active oncologic disease/ antineoplastic therapy with Sars-Cov-2 infection hospitalized between March 1, 2020 and March 1. 2022 were recruited. The primary endpoint was to study the association between the risk categories of the CoVID-TE model and the occurrence of thrombosis using the Chi-Square test. Secondary endpoints were to demonstrate the association between these categories and the occurrence of post-diagnostic Sars-Cov-2 bleeding/ death events. The Kaplan–Meier method was also used to compare mortality by stratification. Results 263 patients were enrolled. 59.3% were men with a median age of 67 years. 73.8% had stage IV disease and lung cancer was the most prevalent tumor (24%). A total of 86.7% had an ECOG 0–2 and 77.9% were receiving active antineoplastic therapy. After a median follow-up of 6.83 months, the incidence of VTE, bleeding, and death 90 days after Sars-Cov-2 diagnosis in the low-risk group was 3.9% (95% CI 1.9–7.9), 4.5% (95% CI 2.3–8.6), and 52.5% (95% CI 45.2–59.7), respectively. For the high-risk group it was 6% (95% CI 2.6–13.2), 9.6% (95% CI 5.0–17.9), and 58.0% (95% CI 45.3–66.1). The Chi-square test for trends detected no statistically significant association between these variables (p > 0.05). Median survival in the low-risk group was 10.15 months (95% CI 3.84–16.46), while in the high-risk group it was 3.68 months (95% CI 0.0–7.79). The differences detected were not statistically significant (p = 0.375) (AU)

Psychological factors and prognostic communication preferences in advanced cancer: multicentre study.

OBJECTIVES: Communication regarding prognosis to patients with advanced cancer is fundamental for informed medical decision making. Our objective was to analyse (1) the proportion of subjects with advanced cancer who prefer to know their prognosis, (2) the characteristics associated with patients' preference for prognostic information, (3) the psychological factors that impact the preference to know prognosis and 4) the concordance between preference for prognostic information perceived among physicians and patients. METHODS: A prospective, cross-sectional design was adopted. Data were collected from 748 participants with advanced cancer at 15 tertiary hospitals in Spain. Participants completed the following questionnaires: Mental Adjustment to Cancer; Trust in the Physician; Uncertainty in Illness Scale Patient's Prognostic Preferences. RESULTS: Fifty-two per cent of advanced cancer sufferers preferred to know the prognosis of their disease. Compared with participants who preferred not to know, those who did reported more uncertainty, greater satisfaction with their physician and higher scores on positive attitude (all p=0.001). Thirty-seven per cent of the physicians believed that patients want to know their prognosis, indicating that they underestimate the number of such patients. No significant differences were found regarding preference to know prognosis as a function of sociodemographic and clinical variables. CONCLUSIONS: A substantial proportion of individuals with advanced cancer prefer to know the prognosis of their disease. It appears that knowing their prognosis was mainly motivated by a need to maintain a positive attitude, lessen uncertainty and by satisfaction with the physician. It is important to explore patients' preferences for information to offer more personalised communication.

The differences detected were not statistically significant (p = 0.375). CONCLUSIONS: The data from our series does not validate of the CoVID-TE as a model to predict thrombosis, hemorrhage, or mortality in cancer patients with Sars-Cov-2 infection.

Complete response to third-line treatment with trifluridine/tipiracil (TAS-102) in stage IV colon adenocarcinoma.

A clinical case of a 61-year-old female diagnosed with stage IV right colon adenocarcinoma (unresectable liver and multiple lymph node metastases at the time of diagnosis), Kirsten rat sarcoma viral oncogene homolog (KRAS), neuroblastoma rat sarcoma viral oncogene homolog (NRAS) and v-raf murine sarcoma viral oncogene homolog B (BRAF) wild-type, proficient mismatch repair (pMMR), in whom a complete response to the third-line of systemic treatment with trifluridine/tipiracil (TAS-102) was obtained. The complete response has been maintained for more than 2 years after its suspension.

The AGAMENON-SEOM model for prediction of survival in patients with advanced HER2-positive oesophagogastric adenocarcinoma receiving first-line trastuzumab-based therapy.

Background: Trastuzumab and chemotherapy is the standard first-line treatment in human epidermal growth factor receptor 2 (HER2)-positive advanced gastro-oesophageal cancer. The objective was to develop a predictive model for overall survival (OS) and progression-free survival (PFS) in patients treated with trastuzumab. Methods: Patients with HER2-positive advanced gastro-oesophageal adenocarcinoma (AGA) from the Spanish Society of Medical Oncology (SEOM)-AGAMENON registry and treated first line with trastuzumab and chemotherapy between 2008 and 2021 were included. The model was externally validated in an independent series (The Christie NHS Foundation Trust, Manchester, UK). Results: In all, 737 patients were recruited (AGAMENON-SEOM, n = 654; Manchester, n = 83). Median PFS and OS in the training cohort were 7.76 [95% confidence interval (CI), 7.13-8.25] and 14.0 months (95% CI, 13.0-14.9), respectively. Six covariates were significantly associated with OS: neutrophil-to-lymphocyte ratio, Eastern Cooperative Oncology Group performance status, Lauren subtype, HER2 expression, histological grade and tumour burden. The AGAMENON-HER2 model demonstrated adequate calibration and fair discriminatory ability with a c-index for corrected PFS/OS of 0.606 (95% CI, 0.578-0.636) and 0.623 (95% CI, 0.594-0.655), respectively. In the validation cohort, the model is well calibrated, with a c-index of 0.650 and 0.683 for PFS and OS, respectively. Conclusion: The AGAMENON-HER2 prognostic tool stratifies HER2-positive AGA patients receiving trastuzumab and chemotherapy according to their estimated survival endpoints.

Current professional standing of young medical oncologists in Spain a nationwide survey by the Spanish Society of Medical Oncology + MIR section

Background There is a lack of knowledge about the career paths and employment situation of young medical oncologists. The aim of our study was to evaluate the current professional standing of these professionals in Spain. Methods The Spanish Society of Medical Oncology + MIR section conducted a national online survey in May 2021 of young medical oncology consultants (< 6 years of expertise) and final year medical oncology residents. Results A total of 162 responses were eligible for analysis and included participants from 16 autonomous communities; 64% were women, 80% were consultants, and 20% were residents. More than half of the participants performed routine healthcare activity and only 7% research activity. Almost three quarters (73%) were subspecialized in a main area of interest and almost half of these chose this area because it was the only option available after residency. Half of the respondents (51%) considered working abroad and 81% believed the professional standing in Spain was worse than in other countries. After finishing their residency, only 22 were offered a job at their training hospital. Just 16% of participants had a permanent employment contract and 87% were concerned (score of ≥ 5 on a scale of 1–10) about their job stability. In addition, one quarter of the participants in our study showed an interest in increasing their research activity. Conclusions The choice of subspecialty in medical oncology may depend on job opportunities after residency rather than personal interest. The abundance of temporary contracts may have influenced the job stability concerns observed. Future mentoring strategies should engage in building a long-term career path for young medical oncologists (AU)

Excess weight and anti-PD-1 immune checkpoint inhibitor’s outcomes in non-small cell lung cancer

Immune checkpoint inhibitors are one of the most effective treatments available in advanced non-small cell lung cancer. However, at present, there are no clinical or analytical biomarkers that define which patients benefit with certainty from these treatments. In our study, we evaluated whether excess weight could be a good predictive biomarker of benefit from these drugs.MethodsWe studied a population of 79 patients, divided into a study group with 39 patients diagnosed with non-small cell lung cancer treated with immunotherapy and 40 patients in a control group, diagnosed with different advanced cancers, treated with non-immunotherapy treatment. We analyzed according to the presence of excess weight or not, the treatment’s outcome in the study group and in the control group (objective response, and progression-free and overall survival).ResultsIn our study, we detected a better response rate to immunotherapy in patients with excess weight (62.50 vs 26.08%, OR 4.72, p = 0.02), and a better median progression-free survival (14.19 vs 5.03 months, HR 0.50, p = 0.058) and median overall survival (33.84 months vs 20.76 months, HR 0.43, p = 0.01) in the study group. These findings were specific to the immunotherapy group since in the control group, with patients who did not receive immune checkpoint inhibitors, these findings were not found.ConclusionOur study suggests that patients with excess weight who receive anti-PD-1 immune checkpoint inhibitors diagnosed with non-small cell lung cancer have a better outcome. This effect is specific to patients receiving immunotherapy. (AU)

Role of sex on psychological distress, quality of life, and coping of patients with advanced colorectal and non-colorectal cancer.

BACKGROUND: Patients with advanced gastrointestinal cancer must cope with the negative effects of cancer and complications. AIM: To evaluate psychological distress, quality of life, and coping strategies in patients with advanced colorectal cancer compared to non-colorectal cancer based on sex. METHODS: A prospective, transversal, multicenter study was conducted in 203 patients; 101 (50%) had a colorectal and 102 (50%) had digestive, non-colorectal advanced cancer. Participants completed questionnaires evaluating psychological distress (Brief Symptom Inventory-18), quality of life (EORTC QLQ-C30), and coping strategies (Mini-Mental Adjustment to Cancer) before starting systemic cancer treatment. RESULTS: The study included 42.4% women. Women exhibited more depressive symptoms, anxiety, functional limitations, and anxious preoccupation than men. Patients with non-colorectal digestive cancer and women showed more somatization and physical symptoms than subjects with colorectal cancer and men. Men with colorectal cancer reported the best health status. CONCLUSION: The degree of disease acceptance in gastrointestinal malignancies may depend on sex and location of the primary digestive neoplasm. Future interventions should specifically address sex and tumor site differences in individuals with advanced digestive cancer.

Psychological distress and resilience in patients with advanced cancer during the Covid-19 pandemic: the mediating role of spirituality.

BACKGROUND: The purpose of this study was to investigate the sociodemographic factors related to psychological distress, spirituality, and resilience, and to examine the mediating role of spirituality with respect to psychological distress and resilience in patients with advanced, unresectable cancer during the Covid-19 pandemic. METHODS: A prospective, cross-sectional design was adopted. Data were collected from 636 participants with advanced cancer at 15 tertiary hospitals in Spain between February 2019 and December 2021. Participants completed self-report measures: Brief Resilient Coping Scale (BRCS), Brief Symptom Inventory (BSI-18), and Spiritual well-being (FACIT-Sp). Hierarchical linear regression models were used to explore the mediating role of spirituality. RESULTS: Spirituality was significantly different according to the person's age and marital status. Psychological distress accounted for 12% of the variance in resilience (ß = - 0.32, p < 0.001) and spirituality, another 15% (ß =0.48, p < 0.001). Spirituality acted as a partial mediator in the relationship between psychological distress and resilience in individuals with advanced cancer. CONCLUSIONS: Both psychological distress and spirituality played a role in resilience in cases of advanced cancer. Spirituality can help promote subjective well-being and increased resilience in these subjects.

RESULTS: In our study, we detected a better response rate to immunotherapy in patients with excess weight (62.50 vs 26.08%, OR 4.72, p = 0.02), and a better median progression-free survival (14.19 vs 5.03 months, HR 0.50, p = 0.058) and median overall survival (33.84 months vs 20.76 months, HR 0.43, p = 0.01) in the study group. These findings were specific to the immunotherapy group since in the control group, with patients who did not receive immune checkpoint inhibitors, these findings were not found. CONCLUSION: Our study suggests that patients with excess weight who receive anti-PD-1 immune checkpoint inhibitors diagnosed with non-small cell lung cancer have a better outcome. This effect is specific to patients receiving immunotherapy.

Stoic attitude in patients with cancer from the NEOcoping study: Cross-sectional study.

AIM: Stoicism has been applied to describe a wide range of behaviors in the face of disease and influences an individual's use of coping strategies. This study tested the relationship between stoicism and social support, optimism, psychological distress, and coping strategies in patients with cancer. METHOD: NEOcoping is a multicenter, cross-sectional study. Participants' data were collected using a standardized, self-report form and LSS, MSPSS, Mini-MAC, BSI-18, and LOT-R questionnaires. Linear regression analyses were used to assess the association between stoicism and distress scores in both genders. A total of 932 individuals with non-metastatic, resected cancer were recruited. RESULTS: Males perceived a higher risk of recurrence and toxicity with adjuvant chemotherapy and obtained higher stoic attitude scores than females. Women scored higher on somatization, depression, and anxiety. Patients with high stoicism scores were older and experienced more maladaptive coping (helplessness, anxious preoccupation), and depression, while those with lower stoicism scores had greater perceived social support, optimism, and positive attitude. In both males and females, stoicism correlated negatively with perceived social support, optimism, and positive attitude, and positively with helplessness, anxious preoccupation, and depression. In men, stoicism was directly and negatively associated with social support and optimism, and positively with anxious preoccupation. In women, stoicism was positively associated. In women, stoicism was directly and negatively associated with social support and positively with age and optimism. Stoicism was directly and positively associated with helplessness. DISCUSSION: A stoic attitude was associated with lower social support, reduced optimism, and passive coping strategies (helplessness and anxious preoccupation) in this series of patients with cancer.

Introduction: Breast cancer is the most frequent tumor in Spanish women. Continuous advances in the treatment of this neoplasm, have contributed to progressively improve survival in early stages. In the last years, neoadjuvant treatment has evolved and changes have occurred in the treatment indication and in the results.Material and methodsWe have assessed the temporal evolution of indications and results of neoadjuvant therapy in breast cancer over a 10-year period. We have analyzed the clinical characteristics, the complete pathological response (CRp), overall survival (OS) and progression-free survival (PFS) of all patients with breast cancer treated with neoadjuvant therapy between January 1st 2007 and December 31st 2016.ResultsDuring the study period, 212 patients were treated.  Throughout the 10-year period, we observed that increasingly older patients had been treated (p < 0.001), a greater number of menopausal patients (p = 0.029), a greater number of triple negative and HER2 positive cases. In addition, a larger number of conservative surgeries and sentinel lymph node biopsies had been performed.ConclusionsNeoadjuvant therapy is increasing in patients with breast cancer, especially in subtypes with poor prognosis (triple negative and HER2). The emerging new drugs and treatment in earlier stages has increased the rate of pCR and breast conserving surgery. (AU)

Peripheral Blood Mononuclear Cells Predict Therapeutic Efficacy of Immunotherapy in NSCLC.

In lung cancer immunotherapy, biomarkers to guide clinical decisions are limited. We now explore whether the detailed immunophenotyping of circulating peripheral blood mononuclear cells (PBMCs) can predict the efficacy of anti-PD-1 immunotherapy in patients with advanced non-small-cell lung cancer (NSCLC). We determined 107 PBMCs subpopulations in a prospective cohort of NSCLC patients before starting single-agent anti-PD-1 immunotherapy (study group), analyzed by flow cytometry. As a control group, we studied patients with advanced malignancies before initiating non-immunotherapy treatment. The frequency of PBMCs was correlated with treatment outcome. Patients were categorized as having either high or low expression for each biomarker, defined as those above the 55th or below the 45th percentile of the overall marker expression within the cohort. In the study group, three subpopulations were associated with significant differences in outcome: high pretreatment levels of circulating CD4+CCR9+, CD4+CCR10+, or CD8+CXCR4+ T cells correlated with poorer overall survival (15.7 vs. 35.9 months, HR 0.16, p = 0.003; 22.0 vs. NR months, HR 0.10, p = 0.003, and 22.0 vs. NR months, HR 0.29, p = 0.02). These differences were specific to immunotherapy-treated patients. High baseline levels of circulating T cell subpopulations related to tissue lymphocyte recruitment are associated with poorer outcomes of immunotherapy-treated advanced NSCLC patients.

The Homologous Recombination Deficiency Scar in Advanced Cancer: Agnostic Targeting of Damaged DNA Repair.

BRCA1 and BRCA2 are the most recognized tumor-suppressor genes involved in double-strand DNA break repair through the homologous recombination (HR) system. Widely known for its role in hereditary cancer, HR deficiency (HRD) has turned out to be critical beyond breast and ovarian cancer: for prostate and pancreatic cancer also. The relevance for the identification of these patients exceeds diagnostic purposes, since results published from clinical trials with poly-ADP ribose polymerase (PARP) inhibitors (PARPi) have shown how this type of targeted therapy can modify the long-term evolution of patients with HRD. Somatic aberrations in other HRD pathway genes, but also indirect genomic instability as a sign of this DNA repair impairment (known as HRD scar), have been reported to be relevant events that lead to more frequently than expected HR loss of function in several tumor types, and should therefore be included in the current diagnostic and therapeutic algorithm. However, the optimal strategy to identify HRD and potential PARPi responders in cancer remains undefined. In this review, we summarize the role and prevalence of HRD across tumor types and the current treatment landscape to guide the agnostic targeting of damaged DNA repair. We also discuss the challenge of testing patients and provide a special insight for new strategies to select patients who benefit from PARPi due to HRD scarring.

Prediction of quality of life in early breast cancer upon completion of adjuvant chemotherapy.

Quality of life (QoL) is a complex, ordinal endpoint with multiple conditioning factors. A predictive model of QoL after adjuvant chemotherapy can support decision making or the communication of information about the range of treatment options available. Patients with localized breast cancer (n = 219) were prospectively recruited at 17 centers. Participants completed the EORTC QLQ-C30 questionnaire. The primary aim was to predict health status upon completion of adjuvant chemotherapy adjusted for multiple covariates. We developed a Bayesian model with six covariates (chemotherapy regimen, TNM stage, axillary lymph node dissection, perceived risk of recurrence, age, type of surgery, and baseline EORTC scores). This model allows both prediction and causal inference. The patients with mastectomy reported a discrete decline on all QoL scores. The effect of surgery depended on the interaction with age. Women with ages on either end of the range displayed worse scores, especially with mastectomy. The perceived risk of recurrence had a striking effect on health status. In conclusion, we have developed a predictive model of health status in patients with early breast cancer based on the individual's profile.

Psychometric Properties of the PDRQ-9 in Cancer Patients: Patient-Doctor Relationship Questionnaire.

BACKGROUND: The patient-doctor relationship is an important concept in health care. The aim of this study was to evaluate the psychometric properties, convergent validity, and factorial invariance of the Patient-Doctor Relationship Questionnaire (PDRQ-9). METHOD: Confirmatory factor analysis was conducted to explore the scale's dimensionality and test for strong measurement invariance across sex, age, and tumor site in a prospective, multicenter cohort of 560 patients who completed the PDRQ-9, Health-related Quality of Life Questionnaire (EORTC-QLQ-C30), and Brief Symptom Inventory (BSI) scales. RESULTS: The data supported a unidimensional structure. Thresholds and factor loadings could be constrained to be invariant across sex, age, and tumor site, indicating strong measurement invariance. Scores derived from the unidimensional structure exhibited satisfactory degrees of reliability and determinacy. Evidence of convergent validity was supported by modest positive correlations with functional (p<.001) and global quality-of-life (p<.001) and negative correlations with psychological distress (p<.001). Low satisfaction with the oncologist was associated with anxiety (p=.006), and depression (p=.004). CONCLUSIONS: The PDRQ-9 is a suitable, valid instrument for assessing the quality of patient-doctor relationships in cancer patients.
