ABSTRACT

We investigated expressions of PD-L1, LAG-3, TIM-3, and OX40L as immune checkpoint proteins, and MSI (repetitive short-DNA-sequences due to defective DNA-repair system) status were analyzed with immunohistochemistry from tissue blocks. Of 83 patients, PD-L1 expression was observed in 18.1% (n = 15) of the patients. None of the patients exhibited LAG-3 expression. TIM-3 expression was 4.9% (n = 4), OX40L was 22.9% (n = 19), and 8.4% (n = 7) of the patients had MSI tumor. A low-to-intermediate positive correlation was observed between PD-L1 and TIM-3 expressions (rho: 0.333, p < 0.01). Although PD-L1 expression was higher in grade 3 NET/NEC, MSI status was prominent in grade 1/2 NET.

ABSTRACT

INTRODUCTION: Niraparib, a strong poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitor, contributed significantly to progression-free survival as a maintenance therapy in the platinum-sensitive period in both first-line and recurrent ovarian cancer, regardless of the BRCA mutation. Grade 3-4 anemia, which has a manageable side effect profile, especially hematological, is seen in almost 1 out of every 4 patients. To the best of our knowledge, there has been no reported case of pure red cell aplasia (PRCA) induced by niraparib treatment. CASE REPORT: A 65-year-old woman diagnosed with stage 3 serous carcinoma of the tuba received niraparib front-line maintenance treatment had grade 4 anemia after 3 months of niraparib treatment. She underwent bone marrow aspiration and biopsy because of refractory anemia, which needs red blood cell (RBC) transfusions despite interruption of treatment. MANAGEMENT AND OUTCOME: The patient was treated with 1 mg/kg methyl prednisolone, after histopathological assessment was consistent with PRCA. The hemoglobin count returned to the normal range with steroid treatment. DISCUSSION: In daily practice, it should be kept in mind that in the case of refractory anemia induced by niraparib, the underlying cause might be PRCA and can be improved with steroid administration.

ABSTRACT

BACKGROUND: PD-L1 and VISTA are thought to play a role in escape from the immune system, tumor progression, and treatment response in tumoral tissue. The current study aimed to evaluate the effects of radiotherapy (RT) and chemoradiotherapy (CRT) on PD-L1 and VISTA expression in head and neck cancers. METHODS: PD-L1 and VISTA expression were compared between the primary biopsy taken at the time of diagnosis and refractory tissue biopsies of patients who received definitive CRT or recurrent tissue biopsies of patients who had surgery followed by adjuvant RT or CRT. RESULTS: In total, 47 patients were included. Radiotherapy had no effect on the expression levels of PD-L1 and VISTA in patients with head and neck cancer (p = 0.542 and p = 0.425, respectively). A positive correlation was found between PD-L1 and VISTA expression (p < 0.001; r = 0.560). PD-L1 and VISTA expression in the first biopsy were found to be significantly higher in clinical lymph node-positive patients compared to node-negative patients (PD-L1 p = 0.038; VISTA p = 0.018). The median overall survival of patients with ≥ 1% VISTA expression in the initial biopsy was significantly shorter than that of patients with < 1% VISTA expression (52.4 vs. 110.1 months, respectively; p = 0.048). CONCLUSION: It was found that PD-L1 and VISTA expression did not change with RT or CRT. Further studies are needed to evaluate the relationship of PD-L1 and VISTA expression with RT and CRT.

ABSTRACT

INTRODUCTION: Resistance to immune checkpoint inhibitors (ICI) is a significant issue in metastatic renal cell carcinoma (mRCC), as it is in the majority of cancer types. An important deficiency in immunooncology today is the lack of a predictive factor to identify this patient group. Myeloid-derived suppressor cells (MDSC) are a type of cell that contributes to immunotherapy resistance by inhibiting T cell activity. While it accumulates in the tumor microenvironment and blood, it can also accumulate in lymphoid organs such as the spleen and cause splenomegaly. Therefore we aimed to evaluate the effect of increase in splenic volume, which can be considered as an indirect indicator of increased MDSC cells, on survival outcomes in mRCC patients. METHODS: We analyzed 45 patients with mRCC who received nivolumab as a second-line or subsequent therapy. Splenic volume was analyzed from baseline imaging before starting nivolumab and from control imaging performed within the first 6 months of treatment initiation. Additionally, we analyzed how patients' body mass index (BMI), IMDC risk score, ECOG performance status, nephrectomy status, neutrophil-lymphocyte ratio (NLR), Platelet-to-lymphocyte ratio (PLR) and sites of metastasis. RESULTS: Median splenic volume change was 10% (ranging from - 22% to + 117%) during follow-up. Change in splenic volume was found to be associated with overall survival (OS) and progression-free survival (PFS) (p = 0.025, 0.04). The median PFS in patients with increased splenic volume was 5 months, while it was 17 months in patients without increased splenic volume. (HR 2.1, 95% CI (1-4), p = 0.04). The median OS in patients with increased splenic volume was 9 months, while it was 35 months in patients without increased splenic volume (HR 2.7, 95% CI (1.1-6.2), p = 0.025). In four patients with decreased splenic volume, neither PFS nor OS could reach the median value. Log-rank p value in respectively (0.015, 0.035), The group in which an increase in volume was accompanied by a high NLR had the shortest survival rate. Basal splenic volume was analyzed separately. However, neither PFS nor OS differed significantly. CONCLUSION: Our findings suggest that the change in splenic volume throughout immunotherapy regimens may be utilized to predict PFS and OS in mRCC patients undergoing treatment.

ABSTRACT

PURPOSE: This study aims to investigate the factors that influence financial toxicity and its effects on both quality of life and psychological distress in Turkish cancer patients. METHODS: Data from 400 cancer patients receiving chemotherapy at a public university in Turkey was analyzed. The Comprehensive Score for Financial Toxicity (COST), Patient Health Questionnaire for Depression and Anxiety (PHQ-4), and Functional Assessment of Cancer Therapy-General (FACT-G) were used to measure financial toxicity, psychological distress, and health quality of life, respectively. RESULTS: Patients' median COST score was 22 (SD = 10.1; range: 1-44) and was consistent with mild financial toxicity. Financial toxicity was associated with lower education level (p < 0.001), lower monthly income (p < 0.001), being a woman (p = 0.021), living in another city (p = 0.012), and previous cancer surgery (p = 0.02). A negative and statistically significant correlation was found between financial toxicity and quality of life (r = - 0.139; p = 0.005) and psychological distress (r = - 0.398; p < 0.001). CONCLUSION: This investigation demonstrated that financial toxicity was a significant determinant of quality of life and psychological distress.

ABSTRACT

INTRODUCTION: Breast cancer is the most common cancer in women worldwide. One of the treatment choices used in hormone receptor positive and HER2 expression negative metastatic breast cancer is cyclin dependent kinase 4/6 (CDK) inhibitors. There are differences between the effects and adverse events of all CDK4/6 inhibitors. In this report, we describe a 48-year-old female patient with breast cancer who developed pulmonary infiltrates secondary to drug in the second year of follow-up with Ribociclib therapy. CASE REPORT: The patient who used ribociclib for metastatic breast cancer was admitted to hospital for routine controls. The patient, in the eighth month of ribociclib treatment, had no active complaints. In the patient's imaging, pulmonary infiltrates were detected in the lower lobe of the right lung. MANAGEMENT AND OUTCOME: The drug was continued in the patient who was asymptomatic and had no infectious signs. Pneumonitis, interstitial lung disease, tuberculosis, COVID-19 and other viral agents were excluded in the patient. A minimal increase in pulmonary infiltrates was observed in the follow-up. However, the patient who does not have any complaints is currently continuing ribociclib at 600 mg/day. DISCUSSION: The pulmonary infiltrates that developed in the patient increased with continued use of ribociclib, suggesting that this was due to ribociclib. The Naranjo Adverse Drug Reaction Probability Scale also indicates probable relationship.

ABSTRACT

BACKGROUND: The optimal sarcopenia measurement method in patients with a diagnosis of glioblastoma multiforme (GBM) is unknown. It has been found that temporal muscle thickness (TMT) may reflect sarcopenia and be associated with survival, but the relationship between temporal muscle area (TMA) and GBM prognosis has never been evaluated before. The primary outcome of the study was to evaluate the relationship between TMA/TMT and overall survival (OS) time in newly diagnosed GBM patients. METHODS: The data of patients who presented at the university hospital between January 2009 and January 2019 with a confirmed diagnosis of glioblastoma multiforme at the time of diagnosis were analyzed retrospectively. Temporal muscle thickness and TMA were measured retrospectively from preoperative MRIs of patients diagnosed with GBM. Due to the small number of patients and the failure to determine a cut-off value with acceptable sensitivity and specificity using ROC analysis, the median values were chosen as the cut-off value. The patients were basically divided into two according to their median TMT (6.6 mm) or TMA (452 mm2 ) values, and survival analysis was performed with the Kaplan-Meier analysis. RESULTS: The median TMT value was 6.6 mm, and the median TMA value was 452 mm2 . The median overall survival (OS) was calculated as 25.8 months in patients with TMT < 6.6 mm, and 15.8 months in patients with TMT ≥ 6.6 mm (p = 0.29). The median overall survival (OS) of patients with TMA < 452mm2 was 26.3 months, and the group with TMA ≥ 452mm2 was 14.6 months (p = 0.06). The median disease-free survival was 18.3 months (%95 CI: 13.2-23.4) in patients with TMT < 6.6mm, while mDFS was 10.9 (%95 CI: 8.0-13.8) months in patients with TMT ≥ 6.6mm (p = 0.21). The median disease-free survival was found to be 21.0 months (%95 CI: 15.8-26.1) in patients with TMA < 452 mm2 and 10.5 months (%95 CI: 7.8-13.2) in patients with TMA ≥ 452 mm2 (p = 0.018). DISCUSSION: No association could be demonstrated between TMT or TMA and OS of GBM patients. In addition, the median DFS was found to be longer in patients with low TMA. There is an unmet need to determine the optimal method of sarcopenia in GBM patients.

ABSTRACT

Inflammatory myofibroblastic tumors (IMTs) are mesenchymal solid tumors, in which anaplastic lymphoma kinase (ALK) gene rearrangement might be detected. A 48-year-old female presented with IMT of lung, treated with surgery. After a 39-month disease-free survival metastatic recurrence was occurred involving soft tissues both infra- and supradiaphragmatic regions. The biopsies obtained from metastatic regions confirmed the recurrence with ALK rearrangement in immunohistochemistry. Initial partial response observed early in treatment course remained as a stable disease with crizotinib treatment. Although an excellent outcome with overall survival of 57 months was observed in our case, there is not enough information about survivals with crizotinib and the treatment options beyond progression. Therefore, every individual case has a unique value paving the way for more effective treatment.

ABSTRACT

We aimed to compare the efficacy and the safety of the FOLFOX and the FLOT regimens in metastatic gastric cancer (mGC) as first-line treatment. It was a retrospective multicenter observational study. The comparisons between groups were conducted in terms of progression-free survival (PFS), overall survival (OS), objective response rate (ORR) and hematologic adverse events. Seventy-nine patients, diagnosed with mGC between March 2012 and December 2019, treated with FOLFOX (n = 43) or FLOT (n = 36) regimens as first-line treatment were included in the study. The mPFS was 10.9 months [95% confidence interval (CI), 5.8-16.1] in the FLOT arm and 7.1 months (95% CI, 5.1-9.1) in the FOLFOX arm (P < 0.001). The ORR was 63.9% in the FLOT arm and 30.2% in the FOLFOX arm (P = 0.003). The mOS was 13.3 months (95% CI, 11.3-15.4) in the FLOT arm and 10.9 months (95% CI, 8.2-13.5) in the FOLFOX arm (P = 0.103). The hematologic adverse events in all grades were 88.4% (n = 38) in the FOLFOX arm compared with 80.6% (n = 29) in the FLOT arm (P = 0.335). The FLOT regimen might be a preferred option in mGC with an improved PFS and ORR compared with the FOLFOX regimen.

ABSTRACT

Introduction: The objective of this study was to evaluate the clinical and laboratory outcomes of solid cancer patients who were reinfected with COVID-19. Methods: Patients who were tested negative on the COVID-19 PCR test and those with improved clinical conditions after infection with COVID-19 were enrolled in this study. Patients who received a positive COVID-19 PCR test 28 days after the initial positive PCR test were considered as reinfected. Results: A total of 1024 patients with the diagnosis of solid malignancy and COVID-19 PCR positivity were examined. The reinfection rate was 3.1%. Mortality rate of reinfection was 34.3%. The serum ferritin and creatinine values in reinfection were found to be significantly higher than the first infection (respectively; p = 0.015, p = 0.014). Conclusion: This study has demonstrated one of the first preliminary clinical results of COVID-19 reinfection in solid cancer patients.


Plain language summary Solid cancer patients are at a higher risk than general population in terms of COVID-19 infectivity and COVID-19-associated death and disease. It is also known that COVID-19 infection has a more severe course in immunocompromised patients. Solid cancer patients may be a vulnerable subgroup of patients to reinfection with COVID-19. The rate of reinfection was 3.1% (n = 32) in our study population of 1024 solid cancer patients who were tested positive on a COVID-19 PCR test. The death rate of the patients with solid cancer was 34.3% (n = 11). In addition, we demonstrated that intensive care follow-up is significantly longer during the reinfection period. It was demonstrated that the time between the last dose of chemotherapy for the patients and the reinfection COVID PCR positivity did not affect the death rate. The COVID-19 pandemic has affected people's daily lives and treatments in many aspects. Owing to the high death rate of reinfection, even if cancer patients have reinfection, our approach is to continue cancer treatment as soon as the patient is cured. Finally, we support the priority vaccination of cancer patients.

ABSTRACT

Background: The efficacy and safety of trifluridine/tipiracil (FTD/TPI) for third-line treatment of metastatic colorectal cancer have been demonstrated. The authors present the Turkish post hoc analysis of the PRECONNECT study. Methods: An international, multicenter, single-arm, open-label, phase IIIb trial evaluating FTD/TPI in patients with ≥2 previous lines of chemotherapy for metastatic colorectal cancer was conducted. The primary end point was safety. Results: In this Turkish cohort (n = 100; eight centers), the most frequent treatment-emergent adverse event was neutropenia (48%). Median progression-free survival was 3.0 months; disease control rate was 36%; quality of life remained stable. Conclusion: Outcomes with FTD/TPI in Turkey are consistent with previous studies and confirm the efficacy and safety of FTD/TPI treatment in the third-line setting. Clinical Trial Registration: NCT03306394 (ClinicalTrials.gov).

ABSTRACT

INTRODUCTION: To evaluate biosimilar understanding and preference trends of medical oncologists in Turkey. METHODS: A survey consisting of 24 multiple-choice questions with checkbox answers was conducted among medical oncologists. The questionnaire was divided into five parts to some intentions: demographic characteristics, general knowledge about biosimilars, knowledge about local approval and reimbursement issues, individual preference trends, and ranking the knowledge of their own. All answers were analyzed as whole cohort, specialists and fellows. RESULTS: Fellows (n = 47) consisted 42%, and academic clinicians (n = 37) consisted 35% of the participants. In the whole cohort, the overall rate of correct answers was 55.1% in the general knowledge about the biosimilars part, and 26.7% in the local approval and reimbursement issues part. At all, 57.7% of the participants declared that they object to switch from a reference product to a biosimilar product. The rate of those who defined themselves as extremely knowledgeable decreased from 8.1% to 2.7% in the whole cohort at the end of the survey. CONCLUSION: The need for more accurate and clarified local regulations and education emerging in the biotechnology era must be met.

ABSTRACT

BACKGROUND: The aim of our study was to compare the efficacy and the safety of the FLOT and the modified DCF (mDCF) regimens in patients with metastatic gastric (GC) and gastroesophageal junction (GEJ) adenocarcinoma as first-line treatment. METHODS: The medical records of 72 patients were retrospectively reviewed. Survivals and hematological adverse events of the patients were examined. Factors affecting survivals were analyzed in univariate analysis. A multivariate analysis was performed with the factors contributing to survivals in univariate analysis. RESULTS: The median PFS (mPFS) was 10.1 months (95% CI, 6.8-13.4) in the FLOT arm (n = 33) and 7.4 months (95% CI, 9.1-21.6) in the mDCF arm (n = 39) (p = 0.041). The median OS (mOS) was 12.9 months (95% CI, 9.7-16.1) in the FLOT arm and 15.4 months (95% CI, 9.1-21.6) in the mDCF arm (p = 0.622). It was found that all grade neutropenia was 51.3% vs. 72.7% (p = 0.063), febrile neutropenia was 8.3% vs. 6.3% (p = 0.743), and thrombocytopenia was 48.7% vs. 51.5% (p = 0.813) in the FLOT and mDCF arms, respectively. Anemia was 59% in the FLOT arm and 100% in the mDCF arm (p < 0.001). Grade 3-4 anemia was 7.7% in the FLOT arm and 24.2% in the mDCF arm (p = 0.052). DISCUSSION: It was shown that the mPFS was significantly increased in the FLOT arm compared to the mDCF arm as the first-line treatment in patients with metastatic GC and GEJC. Hematological adverse events were more favorable in the FLOT arm than in the mDCF arm.

ABSTRACT

We present demographic, clinical, laboratory characteristics and outcomes of the patients with solid malignancies and novel coronavirus disease (COVID-19) collected from the National COVID-19 Registry of Turkey. A total of 1523 patients with a current or past diagnosis of solid tumors and diagnosed with COVID-19 (confirmed with PCR) between 11 March and 20 May 2020 were included. The primary outcome was 30-day mortality. Median age was 61 (range: 18-94), and 752 (49%) were male. The most common types of cancers were breast (19.8%), prostate (10.9%) and colorectal cancer (10.8%). 65% of the patients had at least one comorbidity. At least one COVID-19-directed therapy was given in 73% of the patients.. Hospitalization rate of the patients was 56.6% and intensive care unit admission rate was 11.4%. Seventy-seven (5.1%) patients died within 30 days of diagnosis. The first multivariate model which included only the demographic and clinical characteristics showed older age, male gender and presence of diabetes and receipt of cytotoxic therapy to be associated with increased 30-day mortality, while breast and prostate cancer diagnoses were associated with lower 30-day mortality. In the second set, we further included laboratory parameters. The presence of leukocytosis (OR 6.7, 95% CI 3.3-13.7, P < .001), lymphocytopenia (OR 3,1, 95% CI 1,6-6,1, P = .001) and thrombocytopenia (OR 3,4 95% CI 1,5-8,1, P = .005) were found to be associated with increased 30-day mortality. Relatively lower mortality compared to Western countries and China mainly results from differences in baseline risk factors but may also implicate the importance of intensive supportive care.

ABSTRACT

Aim: To evaluate the immunogenicity and safety of the CoronaVac vaccine in patients with cancer receiving active systemic therapy. Methods: This multicenter, prospective, observational study was conducted with 47 patients receiving active systemic therapy for cancer. CoronaVac was administered as two doses (3 µg/day) on days 0 and 28. Antibody level higher than 1 IU/ml was defined as 'immunogenicity.' Results: The immunogenicity rate was 63.8% (30/47) in the entire patient group, 59.5% (25/42) in those receiving at least one cytotoxic drug and 100% (five of five) in those receiving monoclonal antibody or immunotherapy alone. Age was an independent predictive factor for immunogenicity (odds ratio: 0.830; p = 0.043). Conclusion: More than half of cancer patients receiving active systemic therapy developed immunogenicity.

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate the effect of the serum albumin/globulin ratio (AGR) on the 30-day mortality of febrile neutropenia (FEN). The second aim of the study was to evaluate the effect of the combination of the AGR with the Multinational Association for Supportive Care in Cancer (MASCC) and Clinical Index of Stable Febrile Neutropenia (CISNE) risk indexes on 30-day mortality of FEN. METHODS: A retrospective study evaluating the effect of serum AGR, MASCC and CISNE scores on 30-day FEN mortality. RESULTS: A total of 137 FEN episodes in 120 patients were included in this study. Nineteen patients (14%) died within the first 30 days of FEN episodes. The 30-day mortality rate was calculated as 4% in patients with high AGR and 23% in patients with low AGR (P = .002). According to the MASCC and CISNE risk scores, the mortality rates in low-risk patients were 8% and 6%, respectively, and in the high-risk group 22% and 29%, respectively (P = .024 vs P < .001). In the group of patients with MASCC <21 and CISNE ≥3, the 30-day mortality rate was 7%, when the AGR was >1.13, and in those with AGR ≤1.13 mortality rate increased to 50% (P = .012). CONCLUSION: A low AGR in a patient with FEN was found to be associated with an increased risk of 30-day mortality. Combining the AGR with MASCC and CISNE risk indexes might increase the predictive value of these scoring systems on 30-day mortality.

ABSTRACT

Background/aim: The purpose of this study was to compare efficacy and safety of a combination chemotherapy regimen consisting of oxaliplatin, irinotecan, fluorouracil, and leucovorin (FOLFIRINOX) and gemcitabine-cisplatin as first-line therapy in patients with pancreatic cancer. Materials and methods: Pancreaticobiliary cancer patients who had Eastern Cooperative Oncology Group performance status score of 0 or 1 (on a scale of 0 to 5, with higher scores indicating greater severity of illness) were evaluated to receive folfirinox or gemcitabine plus cisplatin. The primary endpoints were progression-free and overall survival time. Safety analysis was also evaluated as secondary measures. Results: There were 32 patients in the folfirinox group and 36 patients in the gemcitabine-cisplatin group. The median overall survival was 18.1 months (7.5­28.7) in the folfirinox group as compared with 9.7 months (6.5­13) in the gemcitabine-cisplatin group (p = 0.009). Median progression-free survival was 16.2 months (9­23.4) in the folfirinox group and 6.9 months (6.1­7.6) in the gemcitabine- cisplatin group (p = 0.001). Conclusion: Folfirinox is an option for the first-line treatment of patients with pancreatic cancer and good performance status.

ABSTRACT

BACKGROUND: Although staff spiritual care provision plays a key role in patient-centered care, there is insufficient information on international variance in attitudes toward spiritual care and its actual provision. METHODS: A cross-sectional survey of the attitudes of Middle Eastern oncology physicians and nurses toward eight examples of staff provision of spiritual care: two questionnaire items concerned prayer, while six items related to applied information gathering, such as spiritual history taking, referrals, and encouraging patients in their spirituality. In addition, respondents reported on spiritual care provision for their last three advanced cancer patients. RESULTS: Seven hundred seventy responses were received from 14 countries (25% from countries with very high Human Development Index (HDI), 41% high, 29% medium, 5% low). Over 63% of respondents positively viewed the six applied information gathering items, while significantly more, over 76%, did so among respondents from very high HDI countries (p value range, p < 0.001 to p = 0.01). Even though only 42-45% overall were positively inclined toward praying with patients, respondents in lower HDI countries expressed more positive views (p < 0.001). In interaction analysis, HDI proved to be the single strongest factor associated with five of eight spiritual care examples (p < 0.001 for all). Significantly, the Middle Eastern respondents in our study actually provided actual spiritual care to 47% of their most recent advanced cancer patients, compared to only 27% in a parallel American study, with the key difference identified being HDI. CONCLUSIONS: A country's development level is a key factor influencing attitudes toward spiritual care and its actual provision. Respondents from lower ranking HDI countries proved relatively more likely to provide spiritual care and to have positive attitudes toward praying with patients. In contrast, respondents from countries with higher HDI levels had relatively more positive attitudes toward spiritual care interventions that involved gathering information applicable to patient care.

ABSTRACT

OBJECTIVE: When patients feel spiritually supported by staff, we find increased use of hospice and reduced use of aggressive treatments at end of life, yet substantial barriers to staff spiritual care provision still exist. We aimed to study these barriers in a new cultural context and analyzed a new subgroup with "unrealized potential" for improved spiritual care provision: those who are positively inclined toward spiritual care yet do not themselves provide it. METHOD: We distributed the Religion and Spirituality in Cancer Care Study via the Middle East Cancer Consortium to physicians and nurses caring for advanced cancer patients. Survey items included how often spiritual care should be provided, how often respondents themselves provide it, and perceived barriers to spiritual care provision.ResultWe had 770 respondents (40% physicians, 60% nurses) from 14 Middle Eastern countries. The results showed that 82% of respondents think staff should provide spiritual care at least occasionally, but 44% provide spiritual care less often than they think they should. In multivariable analysis of respondents who valued spiritual care yet did not themselves provide it to their most recent patients, predictors included low personal sense of being spiritual (p < 0.001) and not having received training (p = 0.02; only 22% received training). How "developed" a country is negatively predicted spiritual care provision (p < 0.001). Self-perceived barriers were quite similar across cultures.Significance of resultsDespite relatively high levels of spiritual care provision, we see a gap between desirability and actual provision. Seeing oneself as not spiritual or only slightly spiritual is a key factor demonstrably associated with not providing spiritual care. Efforts to increase spiritual care provision should target those in favor of spiritual care provision, promoting training that helps participants consider their own spirituality and the role that it plays in their personal and professional lives.
