BACKGROUND
Uterine leiomyosarcomas are rare malignant mesenchymal tumors. The systemic treatment of these tumors includes chemotherapy and radiotherapy. However, there are still a lot of unanswered questions regarding the ideal therapeutic approach.
METHODS
We have conducted a systematic review of the treatment strategies of uterine leiomyosarcomas for the last ten years.
RESULTS
Adjuvant chemotherapy is still a matter of dilemma. Doxorubicin based chemotherapy or the combination of Gemcitabine-Docetaxel are the regimens of choice for the first line setting. Beyond the first line, there are several options;, including chemotherapy, targeted therapy, and recently efforts of introducing immunotherapy to the therapeutic armamentarium of clinicians treating uterine leiomyosarcomas.
CONCLUSIONS
Despite the efforts of the clinicians dealing with uterine leiomyosarcomas, the optimal therapeutic algorithm is yet to be described.

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.

Meta-Analysis
Doxorubicin (DOX)-induced cardiotoxicity in chemotherapy is a major treatment drawback. Clinical trials on the cardioprotective effects of exercise in cancer patients have not yet been published. Thus, we conducted a systematic review and meta-analysis of preclinical studies for to assess the efficacy of exercise training on DOX-induced cardiomyopathy. We included studies with animal models of DOX-induced cardiomyopathy and exercise training from PubMed, Web of Sciences and Scopus databases. The outcome was the mean difference (MD) in fractional shortening (FS, %) assessed by echocardiography between sedentary and trained DOX-treated animals. Trained DOX-treated animals improved 7.40% (95% CI 5.75-9.05, p < 0.001) in FS vs. sedentary animals. Subgroup analyses revealed a superior effect of exercise training execution prior to DOX exposure (MD = 8.20, 95% CI 6.27-10.13, p = 0.010). The assessment of cardiac function up to 10 days after DOX exposure and completion of exercise protocol was also associated with superior effect size in FS (MD = 7.89, 95% CI 6.11-9.67, p = 0.020) vs. an echocardiography after over 4 weeks. Modality and duration of exercise, gender and cumulative DOX dose did were not individually associated with changes on FS. Exercise training is a cardioprotective approach in rodent models of DOX-induced cardiomyopathy. Exercise prior to DOX exposure exerts greater effect sizes on FS preservation.

Meta-Analysis
BACKGROUND
Treatment with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is standard of care first line treatment for diffuse large B-cell lymphoma (DLBCL), though outcomes remain suboptimal.
METHODS
We performed a systemic review and meta-analysis of randomized controlled trials comparing the efficacy and safety of R-CHOP vs. R-CHOP + X (addition of another drug to R-CHOP) as first line treatment for DLBCL. We searched Cochrane Library, PubMed and conference proceedings up to September 2020.
RESULTS
Our search yielded ten trials including 4206 patients. The added drug was bortezomib or lenalidomide in three trials each, and gemcitabine, bevacizumab and ibrutinib, each drug in one trial. R-CHOP + X was associated with statistically significant improved disease control (HR 0.88, 95% CI 0.78-0.99). The point estimate was in favor of improved overall survival with R-CHOP + X (hazard ratio (HR) 0.87, 95% confidence interval (CI) 0.75-1.00), although this was not statistically significant. Subgroup analysis revealed improved disease control with the addition of lenalidomide and in patients younger than 60 years. R-CHOP + X was associated with an increase in serious adverse events and grade III/IV hematologic toxicity.
CONCLUSION
The addition of another drug to frontline R-CHOP treatment for DLBCL did not result in a significant improvement in OS, although we did observe improved disease control compared to R-CHOP, perhaps most evident with the addition of lenalidomide. Yet, RCHOP + X was associated with an increased risk for serious and hematological adverse events. Further studies could reveal subgroups that would benefit most from augmentation of standard R-CHOP.

Review
INTRODUCTION
Diffuse large B cell Lymphoma (DLBCL) is a potentially curative lymphoma with increasing incidence with ageing. Treatment of elderly DLBCL patients represents a particular challenge due to their comorbidities and performance status.
METHODS
A search for original articles focused on the treatment of elderly DLBCL patients was performed in PubMed database and 633 were found and reviewed. Thirty-eight studies meeting our inclusion criteria were published since 2007.
RESULTS
Thirteen studies were retrospective and 25 phase II/III clinical trials. Most of them investigated the efficacy of dose-adjusted R-CHOP regimen. Alternative therapeutic drugs together with geriatric assessment were also evaluated. For fit patients aged 80 and over, the strongest evidence favours R-miniCHOP regimen.
CONCLUSION
A dose-adjusted R-CHOP may be the recommended treatment in elderly DLBCL patients. New tools such as the Comprehensive Geriatric Assessment provide useful guidance for treatment choice, based on comorbidities and frailty index of this group.

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.

Alveolar rhabdomyosarcoma (ARMS) represents the most common childhood soft tissue sarcoma, but they are rarely seen among adults. Most of the protocols for adults are adapted from pediatric protocols. Here we report a case of a 53-year-old woman diagnosed with a nasal alveolar rhabdomyosarcoma, stage IV at diagnosis, treated by chemotherapy (a regimen inspired from the pediatric protocole pEpSSG RMS 2005) which led to partial response followed by chemo-radiotherapy. We performed a systematic review of adult head and neck ARMS and found 29 cases. Primary chemotherapy with different protocols (VAC, VAI or VIE) should be done followed by surgery and/or external beam radiotherapy (preferably with IMRT). EBRT seems beneficial to every ARMS with a dose around 50Gy in a conventional fractionation, eventually completed with a boost on residual tumor. The target volume must be defined on pre-chemotherapy imaging. Brachytherapy and proton therapy are under evaluation.

Meta-Analysis
OBJECTIVE
Doxorubicin- and epirubicin-induced cardiotoxicities are life threatening for those suffering from breast cancer. Comparing the effects of different strategies on the prevention of these agent-induced cardiotoxicities remains unexplored. A comprehensive review of clinical trials was performed on the prevention of epirubicin- and/or doxorubicin-induced cardiotoxicity in HER2-positive metastatic breast cancer patients. The reduction in ejection fraction was directed at evaluating cardiac toxicity. Fourteen articles evaluated cardiotoxicity as a condition among 2945 individuals, evaluating doxorubicin, epirubicin, Liposomal Doxorubicin (LD), Pegylated Liposomal Doxorubicin (PLD), dexrazoxane plus doxorubicin or epirubicin, and Angiotensin-Converting Enzyme Inhibitors (ACEIs) plus doxorubicin. Pooled Odds Ratio (OR) of 0.043 with a 95% credible interval (CrI) between 0.005 and 0.22 indicated that the dexrazoxane plus epirubicin reduced the number of cardiac events compared with doxorubicin. Furthermore, doxorubicin and epirubicin represented the most effective interventions with a 52% probability of success. Also, the best treatment for reducing Congestive Heart Failure (CHF) was dexrazoxane plus epirubicin with a probability of 43%. For the Left Ventricular Ejection Fraction (LVEF) reduction outcome, ACEIs plus doxorubicin was ranked first with a success probability of 61.2% and they could significantly prevent the reduction in LVEF compared with LD, epirubicin, or doxorubicin.
CONCLUSION
Our data suggested that angiotensin-converting enzyme inhibitors and dexrazoxane plus epirubicin were the most effective interventions for preventing cardiotoxicity and CHF. However, ACEIs plus doxorubicin was the best treatment for preventing LVEF reduction.

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.

Meta-Analysis
PURPOSE
To investigate the effects of mitoxantrone and daunorubicin in induced chemotherapy on complete remission (CR), death during induction therapy, overall survival (OS), disease-free survival (DFS), and relapse in patients of all ages with acute myeloid leukemia (AML).
METHODS
We searched published reports at the Medline, Embase, and Cochrane Databases as well as other databases from inception through July 2019. There was no restriction on date of publication or language (PROSPERO registration CRD42018095843).
RESULTS
We enrolled 12 randomized controlled trials that included data of 4583 AML patients whose disease was untreated or relapsed/refractory, and compared the CR, death during induction therapy, DFS, and OS between mitoxantrone and daunorubicin. Mitoxantrone significantly increased the CR rate (relative risk = 1.07; 95% confidence interval [CI], 1.01, 1.14; P = .03) and DFS (hazard ratio = 0.87; 95% CI, 0.79, 0.96; P = .005) compared to daunorubicin. However, there was no significant difference in death during induction therapy (relative risk = 1.00; 95% CI, 0.81, 1.24; P = .99) and OS (hazard ratio = 0.94; 95% CI, 0.87, 1.01; P = .077) between the two drugs.
CONCLUSION
Although more studies are needed to compare mitoxantrone with higher-dose daunorubicin, the results showed that compared to daunorubicin, mitoxantrone can significantly improve CR and DFS in patients of all ages. These findings suggest that mitoxantrone may be a better choice than daunorubicin as an induction chemotherapy agent for AML patients, especially in developing countries.
