Review
BACKGROUND
PIPAC consists in delivering normothermic chemotherapy solution directly into the peritoneal cavity as an aerosol under pressure. Currently PIPAC is considered as a palliative treatment for patients suffering from non-resectable peritoneal carcinomatosis. We performed a SR to assess tolerance and response of this novel method among patient with OC.
METHODS
We searched electronic database PubMed, Embase, Web of Science, Clinical Trials.gov. We only included clinical studies reporting PIPAC with cisplatin and doxorubicin in patients with ovarian cancer.
RESULTS
This systematic review included 4 studies. In 3 studies all patients were pretreated with cytoreductive surgery, in 1 study surgery was performed in 8/34 (23 %) patients. Mean PCI at first PIPAC procedure ranged from 16.3 to 19.6. All studies reported the proportion of patients with ascites at the first PIPAC with a pooled rate of 48,3 %. Pooled rate of CTCAE Grade 3 toxicity calculated on the total number of PIPAC was 6 % and Grade 4 was 0.9 %. One study reported two cases of small bowel perforation related or potentially related to PIPAC. On study reported a cumulative survival after 400 days of 62 % and a mean actuarial survival time of all patients who underwent PIPAC of 442 days. In another study the mean time to progression was 144 days (95 % CI 122-168 days).
CONCLUSION
This systematic review demonstrated that PIPAC with cisplatin and doxorubicin appear to have a good safety profile with low toxicity and encouraging trend in terms of overall survival.

Meta-Analysis Review
BACKGROUND
Prognosis for patients with metastatic soft tissue sarcomas (STS) is dismal, with median overall survival (OS) of 8-12 months. The role of second-line therapy has been inconsistently investigated over the last 20 years. This systematic review and meta-analysis was performed to assess the efficacy of salvage treatment in pretreated adult type STS, gastrointestinal stromal tumor (GIST) excluded.
MATERIAL AND METHODS
PubMed, Web of Science, SCOPUS, EMBASE, CINAHL, and The Cochrane Library were searched for randomized phase II/phase III trials exploring second- or beyond therapy lines in pretreated metastatic STS. Two independent investigators extracted data; the quality of eligible studies was resolved by consensus. Hazard ratio (HR) of death and progression (OS and progression-free survival [PFS]) and odds ratio (OR) for response rate (RR) were pooled in a fixed- or random-effects model according to heterogeneity. Study quality was assessed with the Cochrane's risk of bias tool, and publication bias with funnel plots.
RESULTS
Overall, 10 randomized trials were selected. The pooled HR for death was 0.81 (95% confidence interval [CI] 0.73-0.9). Second-line therapy reduced the risk of progression by 49% (HR = 0.51, 95% CI 0.34-0.76). This translated into an absolute benefit in OS and PFS by 3.3 and 1.6 months, respectively. Finally, RR with new agents or chemotherapy doublets translated from 4.3% to 7.6% (OR = 1.78, 95% CI 1.22-2.50).
CONCLUSION
Better survival is achieved in patients treated with salvage therapies (chemotherapy, as single or multiple agents or targeted biological agents). A 3-months gain in OS and an almost double RR is observed. Second lines also attained a reduction by 50% the risk of progression.
IMPLICATIONS FOR PRACTICE
There is some evidence that salvage therapies after first-line failure are able to improve outcome in metastatic soft tissue sarcoma (STS). Trabectedin, gemcitabine-based therapy, and pazopanib are currently approved drugs used after conventional upfront treatment. This meta-analysis reviews the benefit of new agents used in randomized trials in comparison with no active treatments or older agents for recurrent/progressed STS. The results show that modern drugs confer a statistically significant 3-month benefit in terms of overall survival, and an increase in response rate. Despite a limited improvement in outcome, currently approved second-line therapy should be offered to patients with good performance status.

Meta-Analysis Review
Optimisation of chemotherapy and radiotherapy for untreated Hodgkin lymphoma patients with respect to second malignant neoplasms, overall and progression-free survival: individual participant data analysis.
BACKGROUND
Efficacy and the risk of severe late effects have to be well-balanced in treatment of Hodgkin lymphoma (HL). Late adverse effects include secondary malignancies which often have a poor prognosis. To synthesise evidence on the risk of secondary malignancies after current treatment approaches comprising chemotherapy and/or radiotherapy, we performed a meta-analysis based on individual patient data (IPD) from patients treated for newly diagnosed HL.
OBJECTIVES
We investigated several questions concerning possible changes in the risk of secondary malignancies when modifying chemotherapy or radiotherapy (omission of radiotherapy, reduction of the radiation field, reduction of the radiation dose, use of fewer chemotherapy cycles, intensification of chemotherapy). We also analysed whether these modifications affect progression-free survival (PFS) and overall survival (OS).
SEARCH METHODS
We searched MEDLINE and Cochrane CENTRAL trials databases comprehensively in June 2010 for all randomised trials in HL since 1984. Key international trials registries were also searched. The search was updated in March 2015 without collecting further IPD (one further eligible study found) and again in July 2017 (no further eligible studies).
SELECTION CRITERIA
We included randomised controlled trials (RCTs) for untreated HL patients which enrolled at least 50 patients per arm, completed recruitment by 2007 and performed a treatment comparison relevant to our objectives.
DATA COLLECTION AND ANALYSIS
Study groups submitted IPD, including age, sex, stage and the outcomes secondary malignant neoplasm (SMN), OS and PFS as time-to-event data. We meta-analysed these data using Petos method (SMN) and Cox regression with inverse-variance pooling (OS, PFS) for each of the five study questions, and performed subgroup and sensitivity analyses to assess the applicability and robustness of the results.
MAIN RESULTS
We identified 21 eligible trials and obtained IPD for 16. For four studies no data were supplied despite repeated efforts, while one study was only identified in 2015 and IPD were not sought. For each study question, between three and six trials with between 1101 and 2996 participants in total and median follow-up between 6.7 and 10.8 years were analysed. All participants were adults and mainly under 60 years. Risk of bias was assessed as low for the majority of studies and outcomes. Chemotherapy alone versus same chemotherapy plus radiotherapy. Omitting additional radiotherapy probably reduces secondary malignancy incidence (Peto odds ratio (OR) 0.43, 95% confidence interval (CI) 0.23 to 0.82, low quality of evidence), corresponding to an estimated reduction of eight-year SMN risk from 8% to 4%. This decrease was particularly true for secondary acute leukemias. However, we had insufficient evidence to determine whether OS rates differ between patients treated with chemotherapy alone versus combined-modality (hazard ratio (HR) 0.71, 95% CI 0.46 to 1.11, moderate quality of evidence). There was a slightly higher rate of PFS with combined modality, but our confidence in the results was limited by high levels of statistical heterogeneity between studies (HR 1.31, 95% CI 0.99 to 1.73, moderate quality of evidence). Chemotherapy plus involved-field radiation versus same chemotherapy plus extended-field radiation (early stages) . There is insufficient evidence to determine whether smaller radiation field reduces SMN risk (Peto OR 0.86, 95% CI 0.64 to 1.16, low quality of evidence), OS (HR 0.89, 95% C: 0.70 to 1.12, high quality of evidence) or PFS (HR 0.99, 95% CI 0.81 to 1.21, high quality of evidence). Chemotherapy plus lower-dose radiation versus same chemotherapy plus higher-dose radiation (early stages). There is insufficient evidence to determine the effect of lower-radiation dose on SMN risk (Peto OR 1.03, 95% CI 0.71 to 1.50, low quality of evidence), OS (HR 0.91, 95% CI 0.65 to 1.28, high quality of evidence) or PFS (HR 1.20, 95% CI 0.97 to 1.48, high quality of evidence). Fewer versus more courses of chemotherapy (each with or without radiotherapy; early stages). Fewer chemotherapy courses probably has little or no effect on SMN risk (Peto OR 1.10, 95% CI 0.74 to 1.62), OS (HR 0.99, 95% CI 0.73 to1.34) or PFS (HR 1.15, 95% CI 0.91 to 1.45).Outcomes had a moderate (SMN) or high (OS, PFS) quality of evidence. Dose-intensified versus ABVD-like chemotherapy (with or without radiotherapy in each case). In the mainly advanced-stage patients who were treated with intensified chemotherapy, the rate of secondary malignancies was low. There was insufficient evidence to determine the effect of chemotherapy intensification (Peto OR 1.37, CI 0.89 to 2.10, low quality of evidence). The rate of secondary acute leukemias (and for younger patients, all secondary malignancies) was probably higher than among those who had treatment with standard-dose ABVD-like protocols. In contrast, the intensified chemotherapy protocols probably improved PFS (eight-year PFS 75% versus 69% for ABVD-like treatment, HR 0.82, 95% CI 0.7 to 0.95, moderate quality of evidence). Evidence suggesting improved survival with intensified chemotherapy was not conclusive (HR: 0.85, CI 0.70 to 1.04), although escalated-dose BEACOPP appeared to lengthen survival compared to ABVD-like chemotherapy (HR 0.58, 95% CI 0.43 to 0.79, moderate quality of evidence).Generally, we could draw valid conclusions only in terms of secondary haematological malignancies, which usually occur less than 10 years after initial treatment, while follow-up within the present analysis was too short to record all solid tumours.
AUTHORS' CONCLUSIONS
The risk of secondary acute myeloid leukaemia and myelodysplastic syndrome (AML/MDS) is increased but efficacy is improved among patients treated with intensified chemotherapy protocols. Treatment decisions must be tailored for individual patients. Consolidating radiotherapy is associated with an increased rate of secondary malignancies; therefore it appears important to define which patients can safely be treated without radiotherapy after chemotherapy, both for early and advanced stages. For early stages, treatment optimisation methods such as use of fewer chemotherapy cycles and reduced field or reduced-dose radiotherapy did not appear to markedly affect efficacy or secondary malignancy risk. Due to the limited amount of long-term follow-up in this meta-analysis, further long-term investigations of late events are needed, particularly with respect to secondary solid tumours. Since many older studies have been included, possible improvement of radiotherapy techniques must be considered when interpreting these results.

Meta-Analysis
Comparison of neoadjuvant treatment and surgery first for resectable or borderline resectable pancreatic carcinoma: A systematic review and network meta-analysis of randomized controlled trials.
BACKGROUND
Current treatment recommendations for resectable or borderline pancreatic carcinoma support upfront surgery and adjuvant therapy. However, neoadjuvant therapy (NT) seems to increase prognosis of pancreatic carcinoma and come to everyone's attention gradually. Randomized controlled trials offering comparison with the NT are lacking and optimal neoadjuvant treatment regimen still remains uncertain. This study aims to compare both treatment strategies for resectable or borderline resectable pancreatic cancer.
METHODS
The PRISMA checklist was used as a guide to systematically review relevant peer-reviewed literature reporting primary data analysis. We searched PubMed, Medline, EMBASE, Cochrane Datebase and related reviews for randomized controlled trials comparing neoadjuvant therapy with surgery first for resectable or borderline resectable pancreatic carcinoma. We estimated relative hazard ratios (HRs) for median overall survival and ratios risks (RRs) for microscopically complete (R0) resection among different neoadjuvant regimens and major complications. We assessed the effects of neoadjuvant therapy on R0 resection rate and median overall survival with Bayesian analysis.
RESULTS
Thirteen eligible articles were included. Eight studies performed comparison neoadjuvant therapy with surgery first, and R0 resection rate was recorded in seven studies. Compared with surgery first, neoadjuvant therapy did increase the R0 resection rate (RR = 1.53, I2 = 0%, P< 0.00001), there was a certain possibility that gemcitabine + cisplatin (Gem+Cis) + Radiotherapy was the most favorable in terms of the fact that there was no significant difference concerning the results from the individual studies. In direct comparison, four studies were included and estimated that Neoadjuvant therapy improved mOS compared with upfront surgery (HR 0.68, 95% CI 0.58-0.92; P = 0.012; I2 = 15%), after Bayesian analysis it seemed that regimen with Cisplatin/ Epirubicin then Gemcitabine/ Capecitabine (PEXG) was most likely the best with a relatively small sample size. The rate of major surgical complications was available for six studies and ranged from 11% to 56% with neoadjuvant therapy and 11% to 45% with surgery first. There was no significant difference between neoadjuvant therapy and surgery first, also with a high heterogeneity (RR = 0.96, 95%CI = 0.65-1.43; P = 0.85; I2 = 46%).
CONCLUSION
In conclusion neoadjuvant therapy might offer benefit over up-front surgery. Neoadjuvant therapy increased the R0 resection rate with gemcitabine + cisplatin + Radiotherapy that was the most favorable and improved mOS with Cisplatin/ Epirubicin then Gemcitabine/ Capecitabine (PEXG) that was most likely the best.

Meta-Analysis Review
BACKGROUND
Autophagy is a mechanism which relies on lysosomes for clearance and recycling of abnormal proteins or organelles. Many studies have demonstrated that the deregulation of autophagy is associated with the development of various diseases including cancer. The use of autophagy inhibitors is an emerging trend in cancer treatment. However, the value of autophagy inhibitors remains under debate. Thus, a meta-analysis was performed, aiming to evaluate the clinical value of autophagy-inhibitor-based therapy.
METHODS
We searched for clinical studies that evaluated autophagy-inhibitor-based therapy in cancer. We extracted data from these studies to evaluate the relative risk (RR) of overall response rate (ORR), 6-month progression-free survival (PFS) rate, and 1-year overall survival (OS) rate.
RESULTS
Seven clinical trials were identified (n = 293). Treatments included 2 combinations of hydroxychloroquine and gemcitabine, 1 combination of hydroxychloroquine and doxorubicin, 1 combination of chloroquine and radiation, 2 combinations of chloroquine, temozolomide, and radiation, and 1 hydroxychloroquine monotherapy. Autophagy-inhibitor-based therapy showed higher ORR (RR: 1.33, 95% confidence interval [CI]: 0.95-1.86, P = .009), PFS (RR: 1.72, 95% CI: 1.05-2.82, P = .000), OS (RR: 1.39, 95% CI: 1.11-1.75, P = .000) values than the therapy without inhibiting autophagy.
CONCLUSION
This meta-analysis showed that autophagy-inhibitor-based therapy has better treatment response compared to chemotherapy or radiation therapy without inhibiting autophagy, which may provide a new strategy for the treatment of cancers.

Comparative Study Meta-Analysis
OBJECTIVE
The objective of this study was to perform a systematic review and meta-analysis to evaluate the two most commonly used chemotherapy regimens gemcitabine plus cisplatin (GC) and methotrexate, vinblastine, doxorubicin/adriamycin, and cisplatin (MVAC) regimens for muscle-invasive bladder cancer (MIBC) patients.
METHODS
We searched for all studies investigating GC and MVAC for MIBC patients in PubMed, Web of Knowledge, and the Cochrane Central Search Library. A systematic review and meta-analysis were performed.
RESULTS
Our searches identified 13 studies among 2174 patients. In the meta-analysis, the pathological complete response to GC regimens was superior to MVAC regimens. No significant difference in pathological partial response was found between the two groups. GC regimens were associated with a significant decrease risk in Grade 3-4 neutropenia, mucositis, and febrile neutropenia, but a significant increase risk in Grade 3-4 thrombocytopenia. There was no significant difference in overall survival (OS), disease-specific survival (DSS) and disease-free survival (DFS) when compared GC regimens to MVAC regimens.
CONCLUSIONS
GC regimens significantly improved pathological complete response compared to MVAC regimens. GC regimens were associated with a significant decrease risk in Grade 3-4 neutropenia, mucositis, and febrile neutropenia, but a significant increase risk in Grade 3-4 thrombocytopenia. There was no significant difference in OS, DSS, and DFS when compared the two regimens.

Meta-Analysis Review
This study systematically reviewed and meta-analysed the prognostic value of complete remission status at end-of-treatment (18) F-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET) in diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP). The systematic PubMed/MEDLINE search yielded seven suitable studies comprising a total of 737 R-CHOP-treated DLBCL patients who were in complete remission at end-of-treatment FDG-PET. Overall, the methodological quality of included studies was reasonable. The disease relapse rate among all patients with complete remission status according to end-of-treatment FDG-PET ranged from 7·0% to 20·0%, with a weighted summary proportion of 13·7%. Five of seven studies reported progression-free survival (PFS) of these patients at various specific time points, i.e., 2-year PFS (n = 1), estimated 3-year PFS (n = 3) and 5-year PFS (n = 1), which was 83%, 85-86·4% and 75%, respectively. Three of seven studies reported overall survival (OS) of these patients at various specific time points, i.e., estimated 3-year OS (n = 2) and estimated 5-year OS (n = 1), which were 90%, 93·6% and 83%, respectively. In conclusion, a non-negligible proportion of R-CHOP-treated DLBCL patients who achieve complete remission according to end-of-treatment FDG-PET experiences disease relapse during follow-up.

The Role of Consolidative Radiotherapy after a Complete Response to Chemotherapy in the Treatment of Diffuse Large B-Cell Lymphoma in the Rituximab Era: Results from a Systematic Review with a Meta-Analysis.
BACKGROUND
The current standard therapy for patients with diffuse large B-cell lymphoma (DLBCL) is rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (RCHOP). The role of radiotherapy (RT) after complete response (CR) to RCHOP in patients with DLBCL remains unclear. This systematic review with a meta-analysis is an attempt to evaluate this role.
METHODS
Studies that evaluated RT versus no-RT after CR to RCHOP for DLBCL patients were searched in databases. Hazard ratios (HR) with their respective 95% confidence intervals (CI) were calculated using a random-effects model.
RESULTS
A total of 4 qualified retrospective studies (633 patients) were included in this review. The results suggested that RT improved overall survival (OS; HR 0.33, 95% CI 0.14-0.77) and progression-free/event-free survival (PFS/EFS; HR 0.24, 95% CI 0.11-0.50) in all patients compared with no-RT. In a subgroup analysis of patients with stage III-IV DLBCL, RT improved PFS/EFS (HR 0.19, 95% CI 0.07-0.51) and local control (HR 0.12, 95% CI 0.03-0.44), with a trend of improving OS (HR 0.35, 95% CI 0.12-1.05).
CONCLUSION
Consolidation RT could significantly improve outcomes of DLBCL patients who achieved a CR to RCHOP. However, the significance of these results was limited by these retrospective data. Further investigation of the role of consolidation RT in the rituximab era is needed.

Meta-Analysis Review
Doxorubicin represents the mainstay in the upfront treatment of diffuse large B-cell lymphoma (DLBCL) patients. However, its administration is sometimes hampered by the coexistence of former comorbidities/cardiac issues, especially in the elderly population. Liposome encapsulated drug delivery systems have been adopted to reduce the exposure of normal tissues to the drug, both in solid cancers and lymphomas. Despite claims for lower toxicity, the efficacy of non-pegylated liposome doxorubicin (NPLD) in DLBCL, as compared to standard doxorubicin, has never been established. We systematically reviewed relevant literature of NPLD in lymphoma treatment. Adjusting for age/comorbidities, our metanalysis revealed that the use of combinations including NPLD (R-COMP) were non-inferior in terms of response, overall and progression-free survival to the standard of care (R-CHOP) in overlapping series of DLBCL patients. R-COMP may represent a safe and active option for elderly patients with DLBCL, or for those with some extent of cardiac impairment at baseline.

Clinical Lymphoma, Myeloma & Leukemia Dec 2018The 2 main formulations of anthracycline used for acute myeloid leukemia (AML) induction therapy are idarubicin (IDA) and daunorubicin. (Meta-Analysis)
Meta-Analysis
BACKGROUND
The 2 main formulations of anthracycline used for acute myeloid leukemia (AML) induction therapy are idarubicin (IDA) and daunorubicin.
PATIENTS AND METHODS
The present systematic review and meta-analysis compared the efficacy and toxicity between IDA and high-dose daunorubicin (HDD) for induction therapy for adult AML. Relevant studies reported before June 2018 were searched from the Medline and Embase databases.
RESULTS
A total of 5 studies with 1809 participants (3 randomized controlled studies and 2 retrospective cohort studies) met the eligibility criteria and were included in the meta-analysis. The patients in the IDA arm for induction therapy had a significantly greater complete response rate after the first course of induction therapy compared with those in the HDD arm (66.7% vs. 61.1%, respectively; odds ratio, 1.23; P = .04; I = 0%). A significantly lower rate of refractory AML was also observed in the IDA group than in the HDD group (16.8% vs. 20.7%, respectively; odds ratio, 0.77; P = .04; I = 0%). However, no difference was found in the long-term overall survival between the 2 groups. Also, the induction mortality rate, febrile neutropenia rate, and cardiotoxicity rate were not significantly different between the 2 groups. The major limitation was the relatively small number of included studies, which could have limited the power of the meta-analysis to demonstrate significant long-term benefits.
CONCLUSION
The complete response rate after the first course of induction therapy was significantly greater among adult patients with AML who had received IDA as part of induction therapy compared with those who had received HDD.
