Meta-Analysis
Bendamustine plus rituximab (BR) and rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP) have been shown to be effective in the treatment of indolent B-cell lymphomas (iBCL). The survival outcomes and adverse events of BR and R-CHOP are still controversial, thus we did a systematic review and meta-analysis to assess them. We searched articles in Pubmed, Cochrane, Embase and Web of Science comparing BR to R-CHOP in patients with iBCL. A total of 3141 patients were included. The results of our meta-analysis revealed that BR has the potential of improving PFS (HR = 0.67, 0.03). No apparent benefit of BR was noted in patients with iBCL for OS (HR = 1.18, 0.04). Compared with R-CHOP, we found that BR regimen had the potential of prolonging PFS, minor toxicity, a better quality of life, and better cost-effectiveness. These results supported BR as a preferred first-line treatment option for patients (especially for elders) with iBCL.

BACKGROUND
Various anticancer drugs are effective therapeutic agents for cancer treatment; however, they cause severe toxicity in body organs. Cardiotoxicity is one of the most critical side effects of these drugs. Based on various findings, turmeric extract has positive effects on cardiac cells.
OBJECTIVE
This study aims to evaluate how curcumin, as the main component of turmeric, may affect chemotherapy- induced cardiotoxicity.
METHODS
A database search was performed up to April 2021 using "curcumin OR turmeric OR Curcuma longa" and "chemotherapy-induced cardiac disease", including their equivalents and similar terms. After screening the total articles obtained from the electronic databases, 25 relevant articles were included in this systematic review.
RESULTS
The studies demonstrate lower body weight and increased mortality rates due to doxorubicin administration. Besides, cancer therapeutic agents induced various morphological and biochemical abnormalities compared to the non-treated groups. Based on most of the obtained results, curcumin at nontoxic doses can protect the cardiac cells mainly through modulating antioxidant capacity, regulation of cell death, and antiinflammatory effects. Nevertheless, according to a minority of findings, curcumin increases the susceptibility of the rat cardiomyoblast cell line (H9C2) to apoptosis triggered by doxorubicin.
CONCLUSION
According to most nonclinical studies, curcumin could potentially have cardioprotective effects against chemotherapy-induced cardiotoxicity. However, based on limited, contradictory findings demonstrating the function of curcumin in potentiating doxorubicin-induced cardiotoxicity, well-designed studies are needed to evaluate the safety and effectiveness of treatment with new formulations of this compound during cancer therapy.

A Systematic Review of the Potential Chemoprotective Effects of Resveratrol on Doxorubicin-Induced Cardiotoxicity: Focus on the Antioxidant, Antiapoptotic, and Anti-Inflammatory Activities.
PURPOSE
Although doxorubicin chemotherapeutic drug is commonly used to treat various solid and hematological tumors, its clinical use is restricted because of its adverse effects on the normal cells/tissues, especially cardiotoxicity. The use of resveratrol may mitigate the doxorubicin-induced cardiotoxic effects. For this aim, we systematically reviewed the potential chemoprotective effects of resveratrol against the doxorubicin-induced cardiotoxicity.
METHODS
In the current study, a systematic search was performed based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline for the identification of all relevant studies on "the role of resveratrol on doxorubicin-induced cardiotoxicity" in the electronic databases of Web of Science, PubMed, and Scopus up to March 2021 using search terms in their titles and abstracts. Two hundred and eighteen articles were screened in accordance with a predefined set of inclusion and exclusion criteria. Finally, 33 eligible articles were included in this systematic review.
RESULTS
The and findings demonstrated a decreased cell survival, increased mortality, decreased heart weight, and increased ascites in the doxorubicin-treated groups compared to the control groups. The combined treatment of resveratrol and doxorubicin showed an opposite pattern than the doxorubicin-treated groups alone. Furthermore, this chemotherapeutic agent induced the biochemical and histopathological changes on the cardiac cells/tissue; however, the results (for most of the cases) revealed that these alterations induced by doxorubicin were reversed near to normal levels (control groups) by resveratrol coadministration.
CONCLUSION
The results of this systematic review stated that coadministration of resveratrol alleviates the doxorubicin-induced cardiotoxicity. Resveratrol exerts these chemoprotective effects through several main mechanisms of antioxidant, antiapoptosis, and anti-inflammatory.

To compare the effectiveness and safety of intensive antileukemic therapy to less-intensive therapy in older adults with acute myeloid leukemia (AML) and intermediate or adverse cytogenetics, we searched the literature in Medline, Embase, and CENTRAL to identify relevant studies through July 2020. We reported the pooled hazard ratios (HRs), risk ratios (RRs), mean difference (MD) and their 95% confidence intervals (CIs) using random-effects meta-analyses and the certainty of evidence using the GRADE approach. Two randomized trials enrolling 529 patients and 23 observational studies enrolling 7296 patients proved eligible. The most common intensive interventions included cytarabine-based intensive chemotherapy, combination of cytarabine and anthracycline, or daunorubicin/idarubicin, and cytarabine plus idarubicin. The most common less-intensive therapies included low-dose cytarabine alone, or combined with clofarabine, azacitidine, and hypomethylating agent-based chemotherapy. Low certainty evidence suggests that patients who receive intensive versus less-intensive therapy may experience longer survival (HR 0.87; 95% CI, 0.76-0.99), a higher probability of receiving allogeneic hematopoietic stem cell transplantation (RR 6.14; 95% CI, 4.03-9.35), fewer episodes of pneumonia (RR, 0.25; 95% CI, 0.06-0.98), but a greater number of severe, treatment-emergent adverse events (RR, 1.34; 95% CI, 1.03-1.75), and a longer duration of intensive care unit hospitalization (MD, 6.84 days longer; 95% CI, 3.44 days longer to 10.24 days longer, very low certainty evidence). Low certainty evidence due to confounding in observational studies suggest superior overall survival without substantial treatment-emergent adverse effect of intensive antileukemic therapy over less-intensive therapy in older adults with AML who are candidates for intensive antileukemic therapy.

Comparative Study Meta-Analysis
Comparison of pegylated liposomal doxorubicin and paclitaxel plus carboplatin-based chemotherapy as first line treatment for patients with ovarian cancer: a systematic review and meta-analysis of randomized controlled trials.
We reviewed studies comparing survival outcomes such as overall survival (OS), progression free survival (PFS), and toxicity profile between patients treated with Pegylated Liposomal Doxorubicin (PLD) combination and those treated with paclitaxel combination for ovarian cancer. We conducted systematic searches in various databases including Medline, Cochrane Controlled Register of Trials (CENTRAL), ScienceDirect, and Google Scholar from inception until August 2019. We used the Cochrane risk of bias tool to assess the quality of published trials. We carried out a meta-analysis with random-effects model and reported pooled Hazard ratios (HR) or Risk ratios (RR) with 95% confidence intervals (CIs). In total, we analysed 7 studies including 3,676 participants. All the studies were randomized controlled trials, while majority of studies had low bias risks. We did not find significant evidence for any of these outcomes except progression free survival (favoured PLD combination therapy pooled HR=0.87; 95% CI: 0.77-0.98). Worst grade toxicities like allergy (pooled RR: 1.86; 95% CI: 1.06-3.24) and neurotoxicity (pooled RR: 5.59; 95% CI: 1.43-21.84) were significantly higher among patients receiving paclitaxel combination therapy when compared to patients receiving PLD combination therapy. To summarize, PLD combination therapy is non-inferior to paclitaxel combination therapy in the management of ovarian cancer with respect to survival outcomes and worst grade toxicity profile. However, clinical recommendations cannot be made, as the evidence is not conclusive or significant enough.

Comparison Between Intravesical Chemotherapy Epirubicin and Mitomycin-C after TURB vs TURB Alone With Recurrence Rate of Non-Muscle Invasive Bladder Cancer: Meta-Analysis.
BACKGROUND
Bladder cancer is still a burden on the world of oncology medicine, which every year affects about 3.4 million people globally with 430,000 new cases per year. It is the fourth most common cancer in men and eighth most common women malignancy in the world. This makes bladder cancer a "silent killer" and it needs appropriate treatment planning. Single immediate instillation of chemotherapy after transurethral resection of the bladder (TURB) is recommended by EAU guideline, but its use remains a controversy.
OBJECTIVE
Study aimed to analyze benefit of intravesical chemotherapy following TURB in terms of recurrency of non-muscle invasive bladder cancer (NMIBC).
METHODS
Systematic review and meta-analysis of randomized controlled trials comparing the efficacy of a single instillation after TURB with TURB alone in NMIBC (pTa-pT1) patients was conducted. Studies searched throughout Medline, PubMed, Embase, and Cochrane in December 2018. Keywords were intravesical chemotherapy, combination, transurethral resection, bladder cancer. Inclusion criteria were RCT studies, subjects in study were treated single immediate chemotherapy instillation after TURB compared to TURB alone in patient with pTa-pT1 urothelial carcinoma of the bladder. Trials with additional treatment prior to first reccurence were not eligible. Studies using recurrence rate as dependent variable. From 361 studies, in total 11 studies were eligible for this meta-analysis.
RESULTS
From those 11 studies, it is shown that intravesical chemotherapy using Epirubicin and Mitomycin-C following TURB showed significant decrease of recurrence rate of bladder cancer even to progression of the disease compared to TURB alone (p<0.05) with pooled Risk Ratio were 0.69 and pooled heterogeneity (I) were 26.6%.
CONCLUSION
This meta-analysis study showed that combination therapy of intravesical chemotherapy after TURB is superior to TURB alone in showing the recurrence rate of NMIBC.

Meta-Analysis
BACKGROUND
It is well known that liposome-based delivery of cytotoxic chemotherapeutics has been proposed as a putative strategy to enhance drug tolerability and efficacy compared to the conventional chemotherapy. However, its potential effect on improving prognosis remains largely unknown. The current meta-analysis is to explore the prognosis of cancer patients undergoing liposomal doxorubicin-based chemotherapy.
METHODS
A detailed review of English and Chinese literature was conducted up to March 21, 2020. We evaluate its possible correlations using hazard ratios (HRs) with 95% confidence intervals (CIs). The pooled data were calculated by STATA software and Review Manager 5.3 software.
RESULTS
Consequently, 26 studies including 7943 patients were satisfied in current analysis. There were no significant differences between liposomal and conventional chemotherapy in OS (HR = 0.98, 95%CI: 0.93-1.04, P = .544) and PFS (HR = 1.00, 95%CI: 0.92-1.10, P = .945). Likewise, subgroup-analysis regarding country, cancer type, and sample sizes also showed the similar results of the 2 paired groups.
CONCLUSION
Taken together, our finding has demonstrated that there was no association of undergoing liposomal doxorubicin-based chemotherapy with cancer prognosis. However, detailed and further studies are needed to confirm our conclusion.

The dilemma of whether to treat elderly patients with diffuse large B-cell lymphoma (DLBCL) with a full or reduced dose intensity (DI) of R-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone+rituximab) is often faced by clinicians. We conducted a systematic review assessing the impact of R-CHOP DI on DLBCL survival outcomes, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols (PRISMA-P) guidelines. We searched MEDLINE, EMBASE, and Cochrane CENTRAL for studies with ≥100 patients treated with R-CHOP/R-CHOP-like therapies published from January 2002 through November 2020. Studies were included if they reported the impact of R-CHOP DI on survival outcomes. We screened records, extracted data, and reviewed all the studies for quality and statistical appraisal. Of 380 screened records, 13 studies including 5188 patients were reviewed. DI was often calculated as the ratio of the cumulative delivered dose of prespecified drug(s) to the cumulative planned dose multiplied by a time-correction factor. Lower DI (intended or relative) was associated with inferior survival in 7 of 9 studies reporting crude survival analyses. Multivariable analysis using DI as a covariate was performed in 10 studies. Six showed an association (P < .05) with adjustment for other covariates, and 4 did not. Most studies and those larger studies of higher quality showed poorer outcomes associated with reduced DI. In subgroups aged ≥80 years, survival was not consistently affected by reduced DI. DI-specific randomized trials are warranted, but these data support full-dose R-CHOP in elderly and fit patients aged <80 years with DLBCL, but not in those aged ≥80 years, where dose-reduced R-CHOP does not appear to compromise survival.

PURPOSE
Considering the increased cancer patient survivorship, the focus is now on addressing the impacts of treatment on quality of life. In young people, altered reproductive function is a major issue and its effects in young males are largely neglected by novel research. To improve clinician awareness, we systematically reviewed side effects of chemotherapy for Hodgkin lymphoma (HL) in young males.
METHODS
The review was prospectively registered (PROSPERO N. CRD42019122868). Three databases (Medline via PUBMED, SCOPUS, and Cochrane Library) were searched for studies featuring males aged 13-51-years who underwent chemotherapy for HL using ABVD (Adriamycin® (doxorubicin), bleomycin, vinblastine, and dacarbazine) or BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone) regimens. These chemotherapy regimens were compared against each other using sperm characteristics, FSH, and inhibin B levels to measure fertility levels.
RESULTS
Data were extracted from five studies featuring 1344 patients. 6 months post-ABVD saw marked deterioration in sperm count, further reduced by more cycles (P = 0.05). Patients treated with BEACOPP rather than ABVD were more prone to oligospermia. Receiving fewer cycles of both regimens increased the likelihood of sperm production recovering. Patients treated with 6-8 cycles of BEACOPP did not recover spermiogenesis.
CONCLUSIONS
ABVD and BEACOPP regimens significantly reduce fertility function to varying effects depending on treatment duration. ABVD temporarily causes significant reductions in male fertility, whereas BEACOPP's effects are more permanent. Therefore, clinicians should discuss fertility preservation with male patients receiving infertility-inducing gonadotoxic therapy. Further high-quality studies are required to more adequality describe the risk to fertility by chemotherapy.

World Journal of Surgical Oncology Feb 2021Isolated primary sacral diffuse large B cell non-Hodgkin's lymphoma is a very rare entity, and only 11 cases have been reported previously.
INTRODUCTION
Isolated primary sacral diffuse large B cell non-Hodgkin's lymphoma is a very rare entity, and only 11 cases have been reported previously.
CASE PRESENTATION
A 36-year-old man was referred with low backache and radiculopathy pain with a clinico-radiological and cytological diagnosis of sacral metastasis. Histopathological examination and immunohistochemistry of image-guided tissue core biopsy from the sacral mass confirmed it as high-grade diffuse large B cell lymphoma (DLBCL). With normal blood counts and bone marrow, and no lesions elsewhere on imaging, he was staged IAE and received 6 cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) regimen chemotherapy followed by radiotherapy. The patient has completed a 3-year follow-up and is doing well with yearly imaging showing no evidence of active disease or recurrence.
CONCLUSIONS
The case shows the importance of an image-guided core biopsy and immunohistochemistry over a fine needle aspiration cytology in select cases as it can alter the treatment and outcome in patients. Because of rarity, the treatment and prognosis in primary sacral NHL is not still very clear as it is treated as per the guidelines of treatment of bone lymphoma.
