RESUMO

BACKGROUND: Peritoneal carcinomatosis significantly worsens the prognosis of patients with gastric cancer. Cytoreduction + hyperthermic intraperitoneal chemotherapy (HIPEC) has shown promising results in the prevention and treatment of peritoneal carcinomatosis in advanced gastric cancer (AGC); however, its application remains controversial owing to the variability of the approaches used to perform it and the lack of high-quality evidence. This systematic review and meta-analysis aimed to investigate the role of surgery and HIPEC in the prevention and treatment of peritoneal carcinomatosis of gastric origin. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials comparing surgery + HIPEC vs surgery + chemotherapy for the prophylaxis of peritoneal carcinomatosis and cytoreduction + HIPEC vs chemotherapy or other palliative options for the treatment of peritoneal carcinomatosis. RESULTS: Sixteen studies enrolling 1641 patients were included. Surgery + HIPEC significantly improved overall survival in both prophylactic (hazard ratio [HR], 0.56) and therapeutic (HR, 0.57) settings. When surgery + HIPEC was performed with prophylactic intent, the pooled 3-year mortality rate was 32%, whereas for the control group it was 55%. The overall and peritoneal recurrence rates were also reduced (risk ratio [RR], 0.59 and 0.40, respectively). No significant difference was found in morbidity between groups (RR, 0.92). CONCLUSION: Based on the current knowledge, HIPEC in AGC seems to be a safe and effective tool for prophylaxis and a promising resource for the treatment of peritoneal carcinomatosis. Regarding the treatment of peritoneal carcinomatosis, the scarcity of large-cohort studies and the heterogeneity of the techniques adopted prevented us from achieving a definitive recommendation.

RESUMO

BACKGROUND: Previous studies on oocyte extract supplementation showed benefits in patients with liver tumours. In this trial, we hypothesized that the oocyte extract supplement impacted the QoL after hepatectomy for hepatocellular carcinoma and intrahepatic cholangiocarcinoma. METHODS: This was a multicentre, double-blind, randomized clinical trial designed to assess the QoL of patients receiving a supplement of oocyte extract or placebo postoperatively. QoL was assessed using the Short Form-36 questionnaire in participants randomly assigned to treatment (Synchrolevels) or placebo. All study personnel and participants were masked to treatment assignment. The endpoint was the change in the QoL score. RESULTS: Between June 2018 and September 2022, 66 of 128 expected patients were considered as per interim analysis, of which 33 were assigned to the treatment and 33 to the placebo group. Baseline and clinicopathological characteristics were similar between the two groups. In the treatment group, the health, mental and psychological status improved for many of the items considered, reaching statistical significance, while in the placebo group, those items either did not change or were impaired in comparison with the corresponding baseline. CONCLUSIONS: Supplementation with oocyte extract modifies QoL after liver surgery by enhancing functional recovery. Further in-depth studies are required to confirm this evidence.

RESUMO

BRCA1 and BRCA2 are the most frequently mutated genes in ovarian cancer (OC) crucial both for the identification of cancer predisposition and therapeutic choices. However, germline variants in other genes could be involved in OC susceptibility. We characterized OC patients to detect mutations in genes other than BRCA1/2 that could be associated with a high risk of developing OC and permit patients to enter the most appropriate treatment and surveillance program. Next-generation sequencing analysis with a 94-gene panel was performed on germline DNA of 219 OC patients. We identified 34 pathogenic/likely pathogenic variants in BRCA1/2 and 38 in other 21 genes. The patients with pathogenic/likely pathogenic variants in the non-BRCA1/2 genes mainly developed OC alone compared to the other groups that also developed breast cancer or other tumors (p = 0.001). Clinical correlation analysis showed that the low-risk patients were significantly associated with platinum sensitivity (p < 0.001). Regarding PARP inhibitors (PARPi) response, the patients with pathogenic mutations in the non-BRCA1/2 genes had worse PFS and OS. Moreover, a statistically significantly worse PFS was found for every increase of one thousand platelets before PARPi treatment. To conclude, knowledge about molecular alterations in genes beyond BRCA1/2 in OC could allow for more personalized diagnostic, predictive, prognostic, and therapeutic strategies for OC patients.

RESUMO

HIGHLIGHTS: Although no definitive data exist in literature, adjuvant chemotherapy is usually recommended in patients with radically resected stage III rectal cancer treated with neo-adjuvant chemo-radiotherapy. We performed a systematic review of literature with direct and indirect comparisons to assess the role of adjuvant mono- or poli-chemotherapy in radically resected rectal cancer treated with neoadjuvant chemo-radiotherapy. Neither chemotherapy (mono-or poli-chemotherapy) nor polichemotherapy with oxaliplatin-containing regimens seems to improve Overall Survival and Disease-Free Survival in patients with radically resected rectal cancer treated with neoadjuvant chemo-adiotherapy. Neither the entire population of patients radically resected after neoadjuvant chemotherapy, nor high risk patients seem to benefit from adjuvant chemotherapy. Our data seem to suggest the need of review the actual international guidelines that suggest the need of adjuvant chemotherapy at least in high risk rectal cancer treated with surgery and neoadjuvant chemo-radiotherapy.

RESUMO

BACKGROUND: Cancer trials involving multiple treatment lines substantially increase our understanding of therapeutic strategies. However, even when the primary end-point of these studies is progression-free survival (PFS), their statistical analysis usually focuses on each line separately, or does not consider repeated events, thus missing potentially relevant information. Consequently, the evaluation of the effectiveness of treatment strategies is highly impaired. METHODS: We evaluated the potentially different effect of bevacizumab (B) administered for the first- or second-line treatment of metastatic colorectal cancer (mCRC) in the ITACa (Italian Trial in Advanced Colorectal Cancer) randomized trial. The ITACa trial consisted of two arms: first-line chemotherapy (CT)+B followed by second-line CT alone versus first-line CT alone followed by second-line CT+B or CT+B+cetuximab according to KRAS status. Cox models for repeated disease progression were performed, and potential selection bias was adjusted using the inverse probability of censoring weighting method. Hazard ratios (HR) [95% confidence interval (CI)] for PFS (primary endpoint) were reported. RESULTS: The overall effect of B across the two lines resulted in a HR = 0.80 (95% CI 0.68-0.95, p = 0.008). Evaluating the differential effect of B in first- and second-line, the addition of B to first-line chemotherapy (CT) produced a 10% risk reduction (HR = 0.90, 95% CI 0.72-1.12, p = 0.340) versus CT alone; B added to second-line CT produced a 36% risk reduction (HR = 0.64, 95% CI 0.49-0.84, p = 0.0011) versus CT alone. CONCLUSION: Our results seem to suggest that B confers a PFS advantage when administered in combination with second-line chemotherapy, which could help to improve current international guidelines on optimal sequential treatment strategies.

RESUMO

Aim: To assess the measures applied to reduce the spread of coronavirus disease (COVID-19) and the timing of their application in medical oncology departments. Materials & methods: We surveyed all medical oncology departments from the Italian Emilia Romagna region via a multidomain questionnaire. The questions covered items on patients, healthcare workers, risk reduction measure and clinical trials. Results: A total of 12 centers involving 861 healthcare members joined the survey. The measures applied to patients and health workers partially converged in all the departments while major divergences were found in the clinical trials domain. High rate of COVID-19 infection occurred among medical doctors (21/208, 10.1%) and social care workers (13/110, 11.8%). Rate of infection among nurses was 5.7% (24/418). Conclusion: All measures able to reduce risk of COVID-19 infection must be applied in medical oncology departments. Early introduction of risk reduction measures may be a critical issue.

RESUMO

This paper is aimed at focusing on the writings and the experience of the Hospice movement Founder, Dame Cicely Saunders. The in-depth analysis carried out had the objective of verifying if "the way" of Cicely to understand, live and propose palliative care was still current and "beautiful", so that we can nowadays refer to her fascinating "Original Palliative Care". With "beauty" we mean, on the one hand, a way able to allow a personal path of research of the meaning of the disease and of the care, both for those who care and for those who are cared for. On the other hand, it seems to us that Cicely strongly suggests how this path can not be carried out alone, but is only possible within the context of a network of relationships and support, in a so called "relational autonomy", for the patient, included in a "care ethics". The authors believe that the work extensively documents as the overall approach of Cicely, traditional but always to be rediscovered, is still today the most convincing way of conception and action of palliative care.

RESUMO

BACKGROUND: Nivolumab was the first immune checkpoint inhibitor approved for previously treated advanced non-small cell lung cancer (NSCLC). Before its introduction in the market, nivolumab was made available to NSCLC patients through an expanded access program (EAP). Here we present the Italian cohort of patients with non-squamous NSCLC enrolled in a worldwide nivolumab EAP, with subgroup analyses involving elderly patients, patients with central nervous system (CNS) metastases and patients receiving nivolumab beyond progression. METHODS: Pretreated patients with advanced non-squamous NSCLC received nivolumab at 3 mg/kg every 2 weeks up to 24 months. Efficacy data (investigator-assessed tumour response, progression date and survival) and safety data were collected. FINDINGS: 1588 patients were treated across 153 Italian centres. Overall response rate and disease control rate were 18% and 44%, respectively; median overall survival (OS) was 11.3 months (95% CI: 10.2-12.4). Elderly patients (≥70 n = 522; ≥75 n = 232) achieved outcomes similar to the global study population; patients with CNS metastases (n = 409) had an OS of 8.6 months (95% CI: 6.4-10.8), and a 1-year OS rate of 43%. Nivolumab was administered beyond progression to 276 patients (26%), 57 of whom achieved subsequent disease control; the median OS of patients receiving nivolumab beyond progression was 16.2 months (95% CI: 14.0-18.4), while 1-year OS rate was 62%. INTERPRETATION: To date, this is the largest clinical experience with nivolumab in a real-world setting. Our data support its use in clinical practice for pretreated non-squamous NSCLC, including patients with older age or CNS metastases.

RESUMO

BACKGROUND/AIM: Brain metastases are an additional challenge in patients with non-small-cell lung cancer (NSCLC) because most chemotherapy agents cannot cross the blood-brain barrier. Nivolumab has demonstrated efficacy in patients with advanced squamous NSCLC, but because patients with central nervous system (CNS) metastases are typically excluded from registration trials, 'field-practice' data are needed. PATIENTS AND METHODS: Patients in the Italian cohort of the Expanded Access Program (EAP) who had CNS metastases at baseline were analyzed. RESULTS: Thirty-seven patients with CNS metastases received a median of six doses of nivolumab. Three patients (8%) had grade 3-4 adverse events and one patient discontinued due to an adverse event. The objective response rate was 19%. Median overall survival was 5.8 (95% confidence interval=1.9-9.8) months and median progression-free survival was 4.9 (95% confidence interval=2.7-7.1) months. CONCLUSION: The safety and efficacy of nivolumab in patients with CNS metastases appear to be similar to those seen in the overall EAP cohort in Italy.

RESUMO

BACKGROUND: The Italian Renal Cell Cancer Early Access Program was an expanded access program that allowed access to nivolumab, for patients (pts) with metastatic renal cell carcinoma (mRCC) prior to regulatory approval. METHODS: Pts with previously treated advanced or mRCC were eligible to receive nivolumab 3 mg/kg every 2 weeks. Pts included in the analysis had received ≥1 dose of nivolumab and were monitored for drug-related adverse events (drAEs) using CTCAE v.4.0. Immune-related (ir) AEs were defined as AEs displaying a certain, likely or possible correlation with immunotherapy (cutaneous, endocrine, hepatic, gastro-intestinal and pulmonary). The association between overall survival (OS) and irAEs was assessed, and associations between variables were evaluated with a logistic regression model. RESULTS: A total of 389 pts were enrolled between July 2015 and April 2016. Overall, the objective response rate was 23.1%. At a median follow-up of 12 months, the median progression-free survival was 4.5 months (95% CI 3.7-6.2) and the 12-month overall survival rate was 63%. Any grade and grade 3-4 drAEs were reported in 124 (32%) and 27 (7%) of pts, respectively, and there were no treatment-related deaths. Any grade irAEs occurred in 76 (20%) of patients, 8% cutaneous, 4% endocrine, 2% hepatic, 5% gastro-intestinal and 1% pulmonary. Of the 22 drAEs inducing treatment discontinuation, 10 (45%) were irAEs. Pts with drAEs had a significantly longer survival than those without drAEs (median OS 22.5 versus 16.4 months, p = 0.01). Pts with irAEs versus without irAEs had a more significant survival benefit (median OS not reached versus 16.8 months, p = 0.002), confirmed at the landmark analysis at 6 weeks. The occurrence of irAEs displayed a strong association with OS in univariable (HR 0.48, p = 0.003) and multivariable (HR 0.57, p = 0.02) analysis. CONCLUSIONS: The appearance of irAEs strongly correlates with survival benefit in a real-life population of mRCC pts treated with nivolumab.

RESUMO

BACKGROUND: Platinum/fluoropyrimidine regimens are the backbone of first-line chemotherapy for advanced gastric cancer (AGC). However response rates to first line chemotherapy range from 30 to 50% and disease progression occurs after 4-6 cycles. The optimal duration of first-line therapy is still unknown and its continuation until disease progression represents the standard. However this strategy is often associated with cumulative toxicity and rapid development of drug resistance. Moreover, only about 40% of AGC pts. are eligible for second-line treatment. METHODS: This is a randomized, open-label, multicenter phase III trial. It aims at assessing whether switch maintenance to ramucirumab plus paclitaxel will extend the progression-free survival (PFS) of subjects with HER-2 negative AGC who have not progressed after 3 months of a first-line with a platinum/fluoropyrimidine regimen (either FOLFOX4, mFOLFOX6 or XELOX). The primary endpoint is to compare Progression-Free Survival (PFS) of patients in ARM A (switch maintenance to ramucirumab and placlitaxel) versus ARM B (continuation of the same first-line therapy with oxaliplatin/fluoropyrimidine). Secondary endpoints are: overall survival, time-to-treatment failure, overall response rate, duration of response, percentage of patients that will receive a second line therapy according to arm treatment, safety, quality of life. Exploratory studies including Next-Generation Sequencing (NGS) in archival tumor tissues are planned in order to identify potential biomarkers of primary resistance and prognosis. DISCUSSION: The ARMANI study estimates if patients treated with early swich with ramucirumab plus paclitaxel received benefit when compared to those treated with continuation of first line therapy. The hypothesis is that the early administration of an active, non-cross resistant second-line regimen such as ramucirumab plus paclitaxel may prolong the time in which patients are progression-free, and consequently have a better quality of life. Moreover, this strategy may rescue all those subjects that become ineligible for second-line therapy due to the rapid deterioration of health status after the first disease progression. TRIAL REGISTRATION: ARMANI is registered at ClinicalTrials.gov ( NCT02934464 , October 17, 2016) and EudraCT(2016-001783-12, April 202,016).

RESUMO

BACKGROUND: The aim of this study was to investigate the role of pre-treatment aspartate aminotransferase-lynphocyte ratio (ALRI) as a predictor of prognosis and treatment efficacy in patients with metastatic colorectal cancer (mCRC) enrolled in the prospective multicenter randomized ITACa (Italian Trial in Advanced Colorectal Cancer) trial to receive first-line chemotherapy (CT) + bevacizumab (B) or CT alone. PATIENTS AND METHODS: Patients randomly received CT+B or CT alone as first-line therapy. CT consisted of either FOLFOX4 or FOLFIRI at the clinician's discretion. RESULTS: Out of the 284 patients enrolled, increased ALRI levels were associated with shorter PFS and OS (p<0.0001). At baseline, median PFS was 10.3 months (95% CI 9.4-12.0) and 8.0 months (95 % CI 6.8-8.9), and median OS was 25.2 months (95 % CI 21.3-30.2) and 18.8 months (95 % CI 16.6-21.7) for patients with low (<14) and high (≥14) ALRI levels, respectively (HR 1.43, 95% CI 1.12-1.82, p=0.004; HR=1.51, 95% CI 1.17-1.96, p<0.001). Interaction tests on ALRI levels and treatment efficacy in the CT+B and the CT groups were statistically significant for PFS (p=0.0003), but not for OS (p=0.228). CONCLUSION: Our results indicate that ALRI is a good prognostic and predictive marker for mCRC patients candidate for CT+B.

RESUMO

INTRODUCTION: Although sorafenib is the upfront standard of care for advanced hepatocellular carcinoma (HCC), molecular predictors of efficacy have not been identified yet. In the ALICE-1 study, rs2010963 of VEGF-A and VEGF-C proved to be independent predictive factors for progression-free survival (PFS) and overall survival (OS) in multivariate analysis. The ALICE-1 study results were confirmed in the ALICE-2 study, in which VEGF and VEGFR SNPs were analyzed. In the ePHAS study we analyzed the SNPs of eNOS. In univariate analysis, patients homozygous for an eNOS haplotype (HT1: T-4b at eNOS-786/eNOS VNTR) had significantly shorter median PFS and OS than those with other haplotypes. These data were confirmed in the validation set. METHODS: This nonpharmacological, interventional, prospective multicenter study aims to determine whether eNOS, HIF-1, VEGF, Ang2 and VEGFR polymorphisms play a role in predicting the objective response rate, PFS, and OS of advanced HCC patients treated with sorafenib. The study will involve 160 advanced HCC patients with Child-Pugh class A disease. The primary aim is to validate the prognostic or predictive roles of eNOS, Ang2, HIF-1, VEGF and VEGFR polymorphisms in relation to the clinical outcome (PFS) of HCC patients treated with sorafenib. CONCLUSIONS: Overall, our data may suggest that polymorphism analysis of the VEGF, VEGFR-2, HIF and eNOS genes can identify HCC patients who are more likely to benefit from sorafenib.

RESUMO

INTRODUCTION: To compare the efficacy of abiraterone acetate, enzalutamide, cabazitaxel and Radium-223 in the treatment of castration-resistant, docetaxel-resistant metastatic prostate cancer. METHODS: An indirect comparison of Overall Survival (OS) and time to PSA progression among abiraterone acetate, enzalutamide, cabazitaxel and Radium-223 was performed with a network metaanalysis. OS in the entire population of patients was the primary endpoint. OS in ECOG 0-1/2, BPISF≤ 4/>4, pretreated with 1 or 2 courses of chemotherapy, age≤65/>65 patients, patients with only bone metastases or bone and visceral metastases, and time to PSA progression were the secondary endpoints. An indirect comparison of the Hazard Ratio and the 95% Confidence Interval was performed, assuming an alpha error of 5% as an index of statistical significance. The among-the-trial heterogeneity was assessed using a qualitative methodological and clinical analysis. RESULTS: Four trials were selected. In three trials, the comparator was placebo, in one trial it was mitoxantrone, the effect of which in improving survival was considered negligible. No significant difference in OS among abiraterone acetate, enzalutamide, cabazitaxel and radium 223 was observed in neither the entire population nor all the subgroups of patients. Enzalutamide resulted significantly better than abiraterone acetate, cabazitaxel or radium-223 in time to PSA progression. CONCLUSION: Since no significant difference in efficacy seems to exist between the four therapeutic options in the treatment of castration-resistant, docetaxel-resistant, metastatic prostate cancer, the safety of the treatment, patient's compliance and costs should represent the criteria to guide clinicians' choice in clinical practice.

RESUMO

The ITACa trial was designed to define the role of cetuximab (Cet) and bevacizumab (Bev) in combination with standard chemotherapy (CT, FOLFIRI or FOLFOX4) as first- and second-line treatment in metastatic colorectal cancer. All patients with WT KRAS tumors who had been enrolled in the first-line trial were randomized onto two independent second-line trials: CT or CT + Cet (study 2A) and CT + Bev or CT + Bev + Cet (study 2B). Patients with mutated KRAS were not eligible for randomization and were treated with CT alone (study 2A) or CT + Bev (study 2B). The primary endpoint was progression-free survival (PFS). 48 and 56 KRAS WT patients were randomized while 31 and 40 KRAS mutated patients were treated without randomization. Study 2A: median PFS was 3.4 (95%CI 2.3-4.6) and 6.2 (95%CI 4.3-7.8) months for the CT and CT + Cet arms, respectively, with a hazard ratio (HR) = 0.64 (95%CI 0.35-1.16, p = 0.144). Study 2B: median PFS was 7.7 (95%CI 4.1-10.1) and 4.9 (95%CI 3.2-7.0) months for CT + Bev and CT + Cet + Bev arms, respectively, with a HR = 1.31 (95%CI 0.76-2.26, p = 0.330). Notwithstanding limitations due to the small sample size, among patients with WT KRAS the addition of Cet to second-line CT increased PFS, whereas the addition of Cet to CT + Bev was associated with worse PFS.

RESUMO

An indirect comparison of cisplatin-pemetrexed (CP) and cisplatin-raltitrexed (CR) was performed. The Odds Ratios of 10, 15 and 20 month survival rate and response rate were assumed as indexes of efficacy; the Odds Ratio of grade III-IV side effects, and the absolute risk of overall, hematologic and non-hematologic toxicity, were assumed as indexes of safety. The outcomes of 352 patients were analysed. The Odds Ratios and 95% Confidence Interval (95% CI) of 10, 15 and 20 months survival rate and response rate were 1.2 (95% CI 0.65-2.24, p = 0.559), 1.02 (95% CI 0.49-2.12, p = 0.953), 1.13 (95% CI 0.44-2.91, p = 0.805) and 0.56 (95% CI 0.26-1.21, p = 0.141), respectively. An absolute increased risk of grade III-IV side effects was observed for CP: 6% (95% CI 3-9%, p < 0.001), 9% (95% CI 2-16%, p = 0.008) and 3% (95% CI 0-5%, p = 0.035) for overall, hematological and non-hematological toxicity. CP and CR can be considered comparable in terms of efficacy in the treatment of metastatic pleural mesothelioma, with a modest increased risk of grade III-IV side effects for CP.

RESUMO

Preliminary studies suggest that capecitabine may be safe and effective in HCC patients. The aim of this study was to retrospectively evaluate the safety and efficacy of metronomic capecitabine as second-line treatment. This multicentric study retrospectively analyzed data of HCC patients unresponsive or intolerant to sorafenib treatment with metronomic capecitabine or best supportive care (BSC).Median progression free survival was 3.1 months in patients treated with capecitabine (95%CI: 2.7-3.5). Median overall survival was 12.0 months (95% CI: 10.7-15.8) in patients receiving capecitabine, while 9.0 months (95% CI: 6.5-13.9) in patients receiving BSC. The result of univariate unweighted Cox regression model shows a 46% reduction in death risk for patients on capecitabine (95%CI: 0.357-0.829; p =0.005) compared to patients receiving BSC alone. After weighting for potential confounders, death risk remained essentially unaltered (45%; 95%CI: 0.354-0.883; p = 0.013). Metronomic capecitabine seems a safe second-line treatment for HCC patients in terms of management of adverse events, showing a potential anti-tumour activity which needs further evaluation in phase III studies.

RESUMO

BACKGROUND: To assess the role of docetaxel plus androgen deprivation in metastatic, hormone- sensitive prostate cancer. METHODS: A qualitative systematic review of literature was performed. All the randomized phase III trials comparing docetaxel plus androgen deprivation with androgen deprivation alone in patients with metastatic, hormone-sensitive prostate cancer were considered eligible and included into the analysis. RESULTS: Six papers (3 randomized clinical trials, and 3 systematic reviews with meta-analysis) were considered eligible and included into the analysis. A significant improvement in time to progression and OS in the entire population treated with docetaxel plus androgen deprivation was reported in all the trials and meta-analyses, and in two trials and all meta-analyses, respectively. One trial reported improvement of OS only in patients with high volume disease, and the meta-analysis that also analyzed the subgroups of patients with high or low volume disease reported a benefit of docetaxel plus androgen deprivation for either the entire population or the two subgroups of patients. CONCLUSION: The early use of docetaxel combined with androgen deprivation improves the main outcomes in the treatment of metastatic, hormone-sensitive prostate cancer. The available data suggest that docetaxel plus androgen deprivation could be considered the novel standard for fit patients with metastatic, hormone-sensitive prostate cancer.

RESUMO

BACKGROUND: In stage IV colorectal cancer, bevacizumab-based maintenance therapy, complete stop therapy and continuous therapy are considered all possible approaches after first line induction chemotherapy. However, there are no clear data about which approach is preferable. MATERIAL AND METHODS: All randomized phase III trials comparing bevacizumab-based maintenance therapy (MB) with complete stop therapy (ST) or with continuous therapy (CT) were considered eligible and included into the analysis. Primary endpoint was the Time to failure strategies (TFS). Secondary endpoints were Overall Survival (OS) and Progression free survival (PFS). Meta-analysis was performed in line with the PRISMA statement. RESULTS: 1892 patients of five trials were included into the analysis. A significant improvement in TFS (HR 0.79; CI 95% 0.7-0.9 p=0.0005) and PFS (HR 0.56; CI 95% 0.44-0.71 p<0.00001) were observed in favour of MB versus ST. A trend, but not statistically significant, in favour of MB versus ST was also observed for OS (HR 0.88; CI 95% 0.77-1.01, p=0.08). Comparing maintenance therapy versus continuous therapy no statistically differences were observed in the outcomes evaluated (OS 12 months OR 1.1 p=0.62, OS 24 months OR 1 p=1, OS 36 months OR 0.54 p=0.3, TFS 12 months OR 0.76 p=0.65). CONCLUSIONS: Our meta-analysis suggests that use of MB approach increases TFS, PFS compared to ST. Although without observing any statistically advantage, it should be highlighted that MB versus ST showed a trend in favour of MB. We observed no difference between MB and CT. MB should be considered the standard regimen in patients with stage IV colorectal cancer after first line induction therapy.
