Review
BACKGROUND
Bendamustine, a bifunctional mechlorethamine alkylating agent, is used in the treatment of patients with hematologic malignancies. Myelosuppression and cytotoxic effect arises quite often after bendamustine treatment. To date, there have been no recommendations for routine chemoprophylaxis for pneumonia (PCP) in patients under treatment with this agent. The present systematic review aimed to evaluate the existing data on bendamustine effects on pneumocystis pneumonia.
METHOD
English papers were systematically reviewed using Web of Science, Embase, Google Scholar, PubMed, and Cochrane library. There was no time constraint for the paper search. The used keywords included "Pneumonia, Pneumocystis"or "Pneumocystis Pneumonia"or "Pneumocystis jirovecii" and "Bendamustine hydrochloride or Bendamustine. "Through our search, 113 papers were found, 26 of which were chosen following a review of the titles and abstracts; ultimately, 10 were included in the research.
RESULT
A total of 10 studies (out of 113 studies) were retrieved. The papers were classified into seven case reports, two clinical trials, and one retrospective analysis study. The case reports included 14 patients diagnosed with PCP after bendamustine administration between 2003 and 2019. The patients' mean age was with a range of 66.8. Non-Hodgkin's lymphoma (including diffuse large B-cell lymphoma and mantle cell lymphoma) ( = 9, 60%), chronic lymphocytic leukemia ( = 4, 26.6%), and breast cancer ( = 2, 13.4%) were the most prevalent types of malignancy. Bendamustine, along with rituximab, were the most commonly prescribed chemotherapy regimens during the treatments. Finally, the mortality rate among the patients whose results were reported ( = 9) was 44.44% ( = 4).
CONCLUSION
The present review described PCP infection in patients with malignancies after the treatment with bendamustine, a chemotherapeutic agent associated with lymphopenia. Further research is required to determine the PCP risk in patients with bendamustine treatment and identify individuals who may benefit from prophylaxis.

Meta-Analysis
BeEAM (Bendamustine, Etoposide, Cytarabine, Melphalan) Versus BEAM (Carmustine, Etoposide, Cytarabine, Melphalan) as Conditioning Regimen Before Autologous Haematopoietic Cell Transplantation: A Systematic Review and Meta-Analysis.
High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is a standard of care for selected patients with refractory/relapsed Hodgkin's lymphoma (HL) or non-Hodgkin's lymphoma (NHL), and it is also used as first-line clinical consolidation option for some aggressive NHL subtypes. Conditioning regimen prior to ASCT is one of the essential factors related with clinical outcomes post transplant. The conditioning regimen of carmustine, etoposide, cytarabine, and melphalan (BEAM) traditionally is considered the standard of care for patients with lymphoma who are eligible for transplantation. Replacement of carmustine with bendamustine (BeEAM) was described as an alternative conditioning regimen in the autograft setting for patients with lymphoma. Several studies have reported inconsistent clinical outcomes comparing BeEAM and BEAM. Therefore, in the lack of well-designed prospective comparative studies, the comparison of BeEAM versus BEAM is based on retrospective trials. To compare the clinical outcomes between BeEAM and BEAM, we performed a meta-analysis of 10 studies which compared the outcomes between BeEAM and BEAM in patients autografted for lymphoma disease (HL or NHL). We searched article titles and compared transplantation with BeEAM versus BEAM in MEDLINE (PubMed), Cochrane library, and EMBASE database. Here, we report the results of nine main endpoints in our meta-analysis comparing BeEAM and BEAM, including neutrophil engraftment (NE), platelet engraftment (PE), overall survival (OS), progression free survival (PFS), non-relapse mortality (NRM), relapse rate (RR), grade 3 mucositis, renal toxicity, and cardiotoxicity. We discovered that the BeEAM regimen was associated with a slightly better PFS [pooled odds ratio (OR) of 0.70, 95% confidence interval (CI), 0.52-0.94, = 0.02], lower RR (0.49, 95% CI, 0.31-0.76, = 0.002), higher mucositis (3.43, 95% CI, 2.29-5.16, = 0.001), renal toxicity (4.49, 95% CI, 2.68-7.51, = 0.001), and cardiotoxicity (1.88, 95% CI, 1.03-3.40, = 0.03). We also discovered that the two groups had equivalent NE (pooled WMD -0.64, 95% CI, -1.46 to 0.18, = 0.13), PE (pooled WMD -0.3, 95% CI, -1.68 to 2.28, = 0.77), OS (0.73, 95% CI, 0.52-1.01, = 0.07), and NRM (1.51, 95% CI, 0.76-2.98, = 0.24). The results of this meta-analysis show that the BeEAM regimen is a viable alternative to BEAM. More prospective comparisons between BeEAM and BEAM are required.

Bendamustine can cause severe autoimmune hemolytic anemia (AIHA), which may require plasma exchange and aggressive immunosuppression. Bendamustine-induced AIHA can be delayed, and many, but not all, cases report prior exposure to fludarabine.

Comparative Study Meta-Analysis
The question of which chemotherapy induction provides the best results for indolent lymphoma patients is yet unanswered. Different regimens have been compared, none of which has been shown to improve overall survival. The use of bendamustine is growing. A number of trials evaluated its efficacy for patients with indolent B-cell lymphoid neoplasms, including chronic lymphocytic leukaemia (CLL). To evaluate the efficacy of bendamustine in that population we performed a systematic review and meta-analysis of 9 randomised controlled trials (2726 patients). Bendamustine was compared to fludarabine-containing regimens, CVP (cyclophosphamide, vincristine, prednisolone), CHOP (CVP+ doxorubicin) and chlorambucil. Due to insufficient reported data, six of the nine trials were included in analysis of overall survival. Bendamustine was associated with a prolonged overall survival, (hazard ratio 0·79, 95% confidence interval 0·65-0·95). Data regarding quality of life was reported for two trials, therefore too scarce to pool. The risk of neutropenia was reduced with bendamustine treatment compared to other chemotherapy. Bendamustine induction is an efficacious option for patients with indolent lymphoma, and CLL. Maintenance therapy was not evaluated after bendamustine induction, and potentially there is an interaction between the two. Chemotherapy-free approach was shown to be efficacious for patients with CLL, while toxicity with that approach is not negligible.
