Prognostic relevance of pretreatment quality of life in diffuse large B-cell lymphoma patients treated with rituximab-CHOP: Results from a prospective cohort study

Health-related quality of life profile of newly diagnosed patients with Hodgkin and non-Hodgkin lymphomas: A real-world study including 3922 patients from the French REALYSA cohort

INTRODUCTION

Considering the notable advances made in the treatment of lymphoma, assessment of health-related quality of life (HRQoL) of lymphoma patients has become a critical aspect to consider both in clinical research and routine practice. However, there is paucity of information about lymphoma specific HRQoL profile at diagnosis.

PATIENTS AND METHODS

HRQoL at diagnosis was assessed for 3922 adult patients with newly diagnosed high-grade (HG) (n = 1994), low-grade (LG) (n = 1053) non-Hodgkin (NHL) and Hodgkin (HL) (n = 875) lymphomas included in REal world dAta in LYmphoma and Survival in Adults (REALYSA, NCT03869619), a prospective non-interventional multicentric cohort in France. Disease-specific HRQoL aspects were assessed with three validated EORTC questionnaires, namely, the QLQ-NHL-HG29, the QLQ-NHL-LG20 and the QLQ-HL27, for patients with NHL-HG, NHL-LG and HL, respectively.

RESULTS

We confirmed the high-level of completion of these questionnaires in REALYSA cohort, ranging from 84 % for QLQ-HG29 to 88 % for QLQ-HL27. The proportion of patients with impaired global health status was as follows: T-cell NHL, 67 %; diffuse large B-cell (DLBCL), 62 %; Burkitt, 61 %; HL, 53 %; marginal zone, 49 %; mantle cell, 48 %; follicular, 47 %. Multivariable regression analyses for DLBCL, follicular and HL showed that gender, performance status and B symptoms were independently associated with all HRQoL dimensions. However, a variable effect of age and stage were observed among these three subtypes.

CONCLUSIONS

A comprehensive analysis was made describing the HRQoL profile of newly diagnosed patients with different types of lymphomas. Our data may help to enhance the interpretation of HRQoL results in future studies using the recently validated EORTC lymphoma specific questionnaires.

Quality of life assessment in diffuse large B-cell lymphoma (DLBCL) in REFLECT: a prospective, non-interventional, multicenter, German study, assessing Sandoz rituximab in combination with CHOP

Health-related quality of life (HRQoL) data are important indicators of health status in patients with lymphoma. The objective of this analysis was to assess the impact of treatment with Sandoz rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) on HRQoL in treatment-naïve adult patients with diffuse large B-cell lymphoma (DLBCL) included in the prospective, real-world REFLECT study. REFLECT is the first prospective study to assess HRQoL in patients with DLBCL treated with a rituximab biosimilar. HRQoL was assessed via the patient-reported European Organization for Research and Treatment of Cancer Core Quality of Life questionnaire at baseline, mid-treatment (month 3), end of treatment (month 6), and follow-up (months 9 and 12). Subgroup analyses were performed to evaluate the influence of baseline characteristics on HRQoL, and associations between baseline HRQoL and treatment response. HRQoL was assessed in 169 patients. Mean global health status score remained stable from baseline (54.8) to mid-treatment (month 3; 54.7), before steadily improving through to end of treatment (month 6; 61.4), and follow-up month 9 (64.9) and month 12 (68.8). Similar trends were observed across most functional and symptom subscales. Higher cognitive, physical, or role functioning, and less appetite loss, diarrhea, fatigue, or pain at baseline, were all associated with an improved likelihood of reaching a complete versus partial response at the end of treatment. Overall, these findings confirm the HRQoL benefits of R-CHOP therapy in treatment-naïve adult patients with DLBCL, and suggest that baseline HRQoL may be predictive of treatment response.

Global quality of life and mortality risk in patients with cancer: a systematic review and meta-analysis

PURPOSE

This systematic review and meta-analysis aimed to examine the impact of global quality of life (QOL) on mortality risk in patients with cancer, considering cancer type and timepoint of QOL assessment.

METHODS

A systematic search was conducted using Cumulated Index to Nursing and Allied Health Literature, PubMed/MEDLINE, and Scopus databases from inception to December 2022. Observational studies that assessed QOL and examined mortality risk in patients with cancer were extracted. Subgroup analyses were performed for cancer types and timepoints of QOL assessment.

RESULTS

Overall, global QOL was significantly associated with mortality risk (hazard ratio: 1.06, 95% confidence interval: 1.05-1.07; p < 0.00001). A subgroup analysis based on cancer type demonstrated that lung, head and neck, breast, esophagus, colon, prostate, hematologic, liver, gynecologic, stomach, brain, bladder, bone and soft tissue, and mixed type cancers were significantly associated with mortality risk; however, melanoma and pancreatic cancer were not significantly associated with mortality risk. Additionally, global QOL was associated with mortality risk at all timepoints (pretreatment, posttreatment, and palliative phase); pretreatment QOL had the largest impact, followed by posttreatment QOL.

CONCLUSION

These findings provide evidence that QOL is associated with mortality risk in patients with cancer at any timepoint. These results indicate the importance of evaluating the QOL and supportive interventions to improve QOL in any phase.

Quality of Life and Survivorship in Lymphoma

PURPOSE OF REVIEW

With an increasing number of long-term lymphoma survivors, there has been emphasis on optimizing quality of life and identifying survivorship challenges. This review summarizes the latest advancements pertaining to health-related quality of life and survivorship in lymphoma.

RECENT FINDINGS

Quality of life can vary from diagnosis through survivorship though some physical, social, and emotional effects may be persistent. Incorporation of patient reported outcomes enables recognition of factors that significantly impact quality of life. A greater understanding of quality of life and survivorship issues has generated momentum for practice change, improving education, and designing behavior related interventions. Patients with lymphoma face many challenges as they navigate their cancer experience. There is a tremendous opportunity to build upon this work through well-designed prospective longitudinal studies aimed at identifying vulnerable patient groups and impactful points of intervention during survivorship.

Patient-reported outcomes provide prognostic information for survival in patients with diffuse large B-cell lymphoma: Analysis of 1239 patients from the GOYA study

Purpose

We investigated the prognostic value of pretreatment patient‐reported outcomes (PROs) in patients with diffuse large B‐cell lymphoma (DLBCL) receiving obinutuzumab/rituximab plus chemotherapy in the GOYA phase III study.

Methods

Patients completed the European Organization for Research and Treatment of Cancer Quality of Life (EORTC QLQ‐C30) and the Functional assessment of chronic illness therapy‐Lymphoma (FACT–Lym) lymphoma subscale (LYMS) during the study. PRO scales with high prognostic value were identified through Cox regression analyses of overall survival (OS) and progression‐free survival (PFS). These scales were evaluated in terms of their additional prognostic value beyond the International Prognostic Index (IPI). A preliminary assessment was performed to evaluate whether the scales provided improved patient‐risk stratification beyond IPI.

Results

One thousand two hundred and fifty‐nine patients with valid pretreatment PRO scales were included in the analyses, and complete pretreatment data were available for 1239/1414 patients (87.6%). Four PRO scales with high prognostic value were identified: FACT–Lym LYMS and EORTC QLQ‐C30 physical functioning, global health status/quality of life (QoL), and fatigue. All four scales retained significant prognostic value for OS and PFS after IPI adjustment (all p < 0.05). After adjusting for multiple clinical variables (IPI, cell of origin, BCL2 status, and total metabolic tumor volume), all four scales retained significant prognostic value (all p < 0.05) for OS. Only the EORTC QLQ‐C30 physical functioning scale was significant (p < 0.05) for PFS after adjustment for multiple clinical variables.

Conclusions

In this large population of patients with DLBCL, pretreatment PROs provided prognostic information for OS and PFS beyond the well‐established IPI.

Quality of life of survivors 1 year after the diagnosis of diffuse large B-cell lymphoma: a LYSA study

Health-related quality of life (HRQoL) is a multidimensional concept including physical, emotional, social, and cognitive functions, disease symptoms, and side effects of treatment. Differences in HRQoL due to gender, existence of comorbidities, and number of chemotherapy cycles are little explored in diffuse large B-cell lymphoma (DLBCL) survivors. Our objective was to investigate whether differences in HRQoL in function of these factors exist 1 year after the diagnosis of DLBCL. One hundred and one patients, enrolled in the RT3 (Real-Time Tailored Therapy) Study, answered self-administrated European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), EORTC High-Grade Non-Hodgkin Lymphoma (NHL-HG29), Hospital Anxiety and Depression Scale (HADS), Post Traumatic Growth Inventory (PTGI), and Multidimensional Fatigue Inventory (MFI) questionnaires. Adjusted means of scores were calculated in multivariate linear regression models. Fifty-seven survivors (mean age of 58.5 years) answered all questionnaires. Women have significantly higher scores of posttraumatic growth and lower physical functioning than men (P < 0.04). Survivors with comorbidities have increased physical fatigue and symptom burden, increased emotional impact, mental fatigue and depression, and reduced physical functioning and global health status (all P < 0.05). A greater number of cycles of chemotherapy increase the level of symptoms (pain, neuropathy, and dyspnoea; P < 0.05). The various aspects related to HRQoL should be discussed with DLBCL patients and investigated, with the aim of developing strategies to ensure appropriate psychosocial and supportive care and to improve the HRQoL in these patients.

Quality of life at diagnosis predicts overall survival in patients with aggressive lymphoma

Our aim was to evaluate whether quality of life (QOL) scores at diagnosis predict survival among patients with aggressive lymphoma. Newly diagnosed lymphoma patients were prospectively enrolled within 9 months of diagnosis in the University of Iowa/Mayo Clinic SPORE and systematically followed for event-free and overall survival (OS). QOL was measured with the Functional Assessment of Cancer Treatment-General (FACT-G), which measures 4 domains: physical, social/family, emotional, and functional well-being (WB); a single item Linear Analogue Self-Assessment (LASA) measuring overall QOL; and a spiritual WB LASA. From 9/2002 to 12/2009, 701 patients with aggressive lymphoma who completed baseline QOL questionnaires were enrolled. At a median follow-up of 71 months (range 6-128), 316 patients (45%) had an event and 228 patients (33%) died. All baseline QOL measures but emotional WB were significantly associated with OS (all P < 0.04); of which all but LASA spiritual remained significant after adjusting for IPI and NHL subtype. The strongest associations were with total FACT-G (adjusted HR = 0.86, 95% CI: 0.79-0.94, P = 0.00062) and functional WB (adjusted HR = 0.88, 95% CI: 0.83-0.93, P < .0001). QOL LASA was associated with OS (adjusted HR = 0.92, 95% CI: 0.87-0.97, P = 0.0041). Patients with clinically deficient QOL (overall QOL ≤50) had a median OS of 92 months compared with 121 months for patients with QOL >50 (P = 0.0004). In this large sample of patients with aggressive lymphoma, we found that baseline QOL is independently predictive of OS. QOL should be assessed as a prognostic factor in patients with aggressive lymphoma.

Health-Related Quality of Life in Non-Hodgkin Lymphoma Survivors: A Prospective Cohort Study

PURPOSE

We evaluated health-related quality of life (HRQOL) in long-term survivors of indolent and aggressive non-Hodgkin lymphoma (NHL).

Materials and Methods

TheHRQOLwas assessed by the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Core 30 (EORTC QLQ-C30) at diagnosis in NHL patients between 2008 and 2011, and follow-up evaluation was conducted from June 2014 to February 2015 using EORTC QLQ-C30 and the quality of life in cancer survivors (QOL-CS) questionnaire. We used linear mixed models to compare changes in HRQOL between indolent and aggressive NHL over time.

RESULTS

The HRQOL of long-term survivors with aggressive NHL improved to the similar level of indolent NHL during the follow-up survey. However, survivors of NHL were found to fear the probability of relapse and second malignancy, and the degree of fear was not different between survivors with aggressive stage I/II or III/IV NHL (p > 0.05). Furthermore, a half of survivors reported impaired sense of psychosocial well-being regardless of aggressiveness and stage during follow-up survey. More than 65% of survivors thought they did not receive sufficient support from others, and patients who had financial difficulties at diagnosis were more frequently associated with suffering from insufficient support. Impaired physical and cognitive functioning at diagnosis was significantly associated with lack of life purpose in long-term survivors.

CONCLUSION

The HRQOL of aggressive NHL survivors improved to a similar level to that of indolent NHL. However, the majority of survivors still had fear of relapse, and psychosocial well-being remained unmet needs.

Rituximab maintenance therapy for patients with diffuse large B-cell lymphoma: A meta-analysis

Purpose

The addition of rituximab to standard chemotherapy has significantly improved survival in patients with lymphoma. Recently, maintenance therapy with rituximab has been shown to prevent relapse and provide survival benefits for patients with follicular or mantle cell lymphoma. However, the effects of rituximab in patients with diffuse large B-cell lymphoma (DLBCL) remain unclear. Two new studies involving rituximab in the treatment of DLBCL were performed this past year. We performed a meta analysis to evaluate the effects of rituximab maintenance treatment of patients with DLBCL.

Methods

Several databases (PubMed, MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials) databases were reviewed for relevant randomized controlled trials published prior to May, 2016. Two reviewers assessed the quality of the included studies and extracted data independently. The hazard ratios (HRs) for time-to-event data and relative risks (RRs) for the other data were pooled and estimated.

Results

Totally 5 studies including 1740 patients were eligible for the meta-analysis. Compared to the observation group, patients who received rituximab maintenance therapy had significantly improved event-free survival (EFS) (HR = 0.80, 95% CI: 0.65–0.98) and progression-free survival (PFS) (HR = 0.72, 95% CI: 0.54–0.94). However, there was no statistically significant difference in overall survival (OS) (HR = 0.66, 95% CI: 0.27–1.29). A subgroup analysis suggested that male patients may benefit from rituximab maintenance therapy with a better EFS (HR = 0.53, 95% CI: 0.34–0.82-), while this advantage was not observed in female patients (HR = 0.99, 95% CI: 0.64–1.52).

Conclusions

Rituximab maintenance may provide survival benefits beyond that afforded by first- and second-line chemotherapy alone, especially in male patients. However, maintenance rituximab treatment may cause more adverse events. It is recommended that both survival benefits and adverse events should be taken into consideration when making treatment decisions.

Diffuse large B-cell lymphoma: R-CHOP failure-what to do?

Although rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is the standard treatment for patients with diffuse large B-cell lymphoma (DLBCL), ∼30% to 50% of patients are not cured by this treatment, depending on disease stage or prognostic index. Among patients for whom R-CHOP therapy fails, 20% suffer from primary refractory disease (progress during or right after treatment) whereas 30% relapse after achieving complete remission (CR). Currently, there is no good definition enabling us to identify these 2 groups upon diagnosis. Most of the refractory patients exhibit double-hit lymphoma (MYC-BCL2 rearrangement) or double-protein-expression lymphoma (MYC-BCL2 hyperexpression) which have a more aggressive clinical picture. New strategies are currently being explored to obtain better CR rates and fewer relapses. Although young relapsing patients are treated with high-dose therapy followed by autologous transplant, there is an unmet need for better salvage regimens in this setting. To prevent relapse, maintenance therapy with immunomodulatory agents such as lenalidomide is currently undergoing investigation. New drugs will most likely be introduced over the next few years and will probably be different for relapsing and refractory patients.

Health-related quality of life in Korean lymphoma survivors compared with the general population

The objective of this study was to evaluate the health-related quality of life (HRQOL) of lymphoma survivors, to compare it with that of the general population, and to identify its predictors in lymphoma survivors. We enrolled 837 participants (mean age, 54.6 years; mean time since diagnosis, 6.3 years) with a history of Hodgkin's lymphoma (HL) (n = 58) or non-Hodgkin's lymphoma (NHL) (n = 779) who had been treated at any of three Korean hospitals from 1989 through 2010. For controls, we selected 1,000 subjects randomly from a representative Korean population. We administered the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and the Hospital Anxiety and Depression Scale. Overall, the HRQOL in both groups of survivors and the general population were comparable, but we observed clinically meaningful worse social functioning in NHL survivors (p < 0.001) and more severe fatigue in HL survivors (p < 0.001) than in the general population. Analysis of covariance revealed no clinically meaningful difference in HRQOL associated with age or sex. Survivors who received peripheral blood stem cell transplants showed clinically meaningful worse role (p = 0.001) and social (p < 0.001) functioning than those who were treated with first-line chemotherapy alone. In multivariate analyses, fatigue, depression, and financial difficulties emerged as the strongest predictors for almost all subscales of functioning and global quality of life. Interventions for alleviating fatigue, depression, and financial difficulties are needed to enhance the HRQOL of Korean lymphoma survivors.
