The objective of this retrospective study (N = 169) was to compare the overall survival (OS) of different subtypes of mantle cell lymphoma (MCL) treated by the Nebraska Lymphoma Study Group between 1984 and 2012. The overall response rate to various therapies including stem cell transplant (SCT) was similar (p = 0.44) between blastoid, diffuse and nodular subtypes. At 5 years, blastoid and diffuse subtypes had worse OS (overallp = 0.005) compared to nodular subtype. In multivariate analysis, the blastoid and diffuse subtypes had similar risk of death (p = 0.14) whereas the nodular subtype had a lower risk compared to blastoid (HR 0.48, 95% CI 0.27–0.87,p = 0.01). The use of SCT was associated with lower risk of death. In univariate analysis, blastoid subtype had better OS with intensive upfront therapy. In conclusion, the OS of blastoid subtype is worse than nodular MCL but may improve with the use of SCT and probably intensive induction therapy. [ABSTRACT FROM AUTHOR]

Clinical practice guidelines are systematically developed statements designed to assist practitioners in making decisions about appropriate healthcare for specific clinical circumstances. Their successful implementation should improve quality of care by decreasing inappropriate variation and expediting the application of effective advances to everyday practice. Despite wide promulgation, guidelines have had limited effect on changing physician behaviors. This two-part review article highlights variations in the current recommended management of lymphoma (Part I) and leukemia (Part II), with some focus on targeted therapies. Focus on variations that may be amenable to educational programs designed for physicians were also considered in the review. For the purpose of this report, 'variation' is defined as any deviation in the treatment or management of a particular hematologic malignancy where practice guidelines exist. Specific studies that demonstrate factors that may cause variations in clinical outcomes of hematologic malignancies and may contribute to variations in practice are featured. [ABSTRACT FROM AUTHOR]

A letter to the editor in response to the article "Transplant related outcomes in patients with hematopoietic stem cell transplant with Clostridium difficile associated diarrhea," that was published in a previous issue of the journal is presented.

Purpose: This study explored the relationship of spirituality and religiosity as it affects the physical and mental quality of life (pQOL, mQOL) of cancer survivors., Methods: This is a prospective observational study that included adults ≥ 19 years who received treatment for various types of cancer. Patients' QOL was obtained at baseline, 6, and 12 months. Cohorts were categorized according to spirituality/religiosity levels: low spirituality-low religiosity (LSLR), low spirituality-high religiosity (LSHR), high spirituality-low religiosity (HSLR), and high spirituality-high religiosity (HSHR)., Results: Of the 551 eligible, 248 (45%) had HSHR, 196 (36%) had LSHR, 75 (14%) had LSLR, and 32 (6%) had HSLR. The pQOL of LSLR were significantly lower than those with HSHR (p = 0.02). The differences in pQOL between LS and HS were observed among those who have HR (p < 0.0001). Among patients with LR, pQOL did not differ. The mQOL of patients with LSLR was significantly lower than those with HSHR (p < 0.0001). The mQOL of those with HS was significantly higher than those with LS in both cohorts having LR (p < 0.0001) or HR (p < 0.0001). pQOL decreased while mQOL increased over time regardless of spirituality or religiosity levels., Conclusion: Spirituality is important in the improvement of both pQOL and mQOL of cancer survivors, while religiosity may have some impact on pQOL. Clinicians' incorporation of spirituality into cancer treatment facilitates well-rounded care, which offers measurable improvements for patients with an illness, of which the treatment is often arduous, and uncertain., (© 2021.

Although a well-established risk factor for lung cancer, the impact of smoking on the survival of non-small cell lung cancer (NSCLC) is not well known. We performed a retrospective analysis of the Veteran's Affairs Comprehensive Cancer Registry of NSCLC patients. Smoking status was categorized as never smoker, past smoker and current smoker based on self-reported history. Multivariate analysis was performed to evaluate the impact of smoking on overall survival (OS) from NSCLC. The study population (n = 61,440) comprised predominantly of males (98 %) and Caucasians (81 %). The median age at diagnosis was 68 years (range 22-108 years). Current smokers were diagnosed with NSCLC at a younger age (65 years) compared to never smokers (71 years) and past smokers (72 years) (p < 0.001). On multivariate analysis, current smokers (n = 34,613) [Hazard ratio (HR) 1.059; 95 % confidence interval (CI) 1.012-1.108], but not past smokers (n = 23,864) (HR 1.008; 95 % CI 0.962-1.056), had worse OS for Stage III and IV NSCLC, compared to never smokers (n = 2,963). Smoking status was not prognostic in stages I and II NSCLC. Current smokers were diagnosed with NSCLC at a younger age than never smokers. Although current smoking was associated with worse prognosis, especially in stages III and IV, the impact of smoking status on OS was modest.
