RESUMO
BACKGROUND/AIMS: The aim of this study was to perform a systematic review on primary retroperitoneal cystoadenocarcinoma (PRC), which is an extremely rare disease. METHODS: According to PRISMA guidelines, all the literature about PRC from 1977 to 2015 was reviewed. Thirty articles were selected; characteristics of the patients were collected and described; time to recurrence and overall survival (OS) were investigated when available. RESULTS: Thirty seven patients were included of whom 33 were females; the median age at presentation was 43. PRC was more common in postmenopausal women. Surgery was the standard therapy; the role of chemotherapy and/or radiotherapy was uncertain. Thirty percent of the patients relapsed after 58 months from the surgery; the rupture of the cyst occurred in 13% of the cases and it was associated with poor prognosis as well as premenopausal status. At 125 months from the diagnosis, 72% of the patients were alive and the median OS was not reached. CONCLUSIONS: The present systematic review about PRC is the first performed until the date of drafting this paper. We described some clinical features of PRC and their possible prognostic value. No conclusive data can be presented due to the small population analyzed and to publication bias.

BACKGROUND: Neuroendocrine Carcinomas (NECs) prognosis is poor.No standard second-line therapy is currently recognized after failure of platinum-based first-line treatment. FOLFIRI and CAPTEM regimens have shown promising activity in preliminary studies. We aimed to evaluate these regimens in metastatic NEC patients. METHODS: This is an open-label, multicenter, randomized non-comparative phase II trial to evaluate the activity and safety of FOLFIRI or CAPTEM in metastatic NEC patients. Primary endpoints were the 12 weeks-Disease Control Rate (12w-DCR) by investigator assessment per RECIST v1.1 and safety per CTCAE v5.0. Additional endpoints included overall response rate (ORR), progression-free survival (PFS) and overall survival (OS). Patients' serum samples were subject to NGS miRNome profiling in comparison with healthy donors to reveal differentially expressed miRNAs as candidate circulating biomarkers. RESULTS: The study was halted for futility at interim analysis, as the minimum 12w-DCR threshold of 10 out of 25 patients required for the first step was not reached. From 06/03/2017 to 18/01/2021, 53 out of 112 patients were enrolled. Median follow-up was 22.6 months (range: 1.4-60.4). The 12w-DCR was 39.1 % in the FOLFIRI arm and 28.0 % in the CAPTEM arm. In the FOLFIRI subgroup the 12-months OS rate was 28.4 % (95 % CI: 12.7-46.5) while in the CAPTEM subgroup it was 32.4 % (95 % CI: 14.9-51.3). The most common G3-G4 side effects were neutropenia (n = 5, 18.5 %) and anemia (n = 2, 7.4 %) for FOLFIRI and G3-G4 thrombocytopenia (n = 2, 8.0 %), G4 nausea/vomiting (n = 1, 4.0 %) for CAPTEM. Three microRNAs emerged as NEC independent predictors. High expression values were found to be significantly associated with decreased PFS and OS. CONCLUSION: The safety profile of FOLFIRI and CAPTEM was manageable. FOLFIRI and CAPTEM chemotherapy showed comparable activity in the second-line setting after progression on etoposide/platinum.

BACKGROUND: Knowledge of clinical course in advanced jejunoileal neuroendocrine tumors (NETs) is poor. AIM: To investigate progression-free survival (PFS), overall survival (OS), and possible predictors for disease progression (DP) in advanced jejunoileal NETs. PATIENTS AND METHODS: We carried out a multicenter, retrospective analysis of incoming patients with sporadic advanced jejunoileal NETs. PFS and OS were assessed by Kaplan-Meier analysis. Risk factors for progression were analyzed by the Cox proportional hazards method. RESULTS: Of the 114 patients enrolled, 46.5% had functioning tumors, 93.9% had stage IV disease, and 57.3 and 42.7% were G1 and G2 tumors, respectively. During a median follow-up of 48 months (interquartile range 29-84 months), DP occurred in 61.4% of patients, after 19 months (interquartile range 10-41 months) from diagnosis. Median PFS was 36 months. The 2-year and 5-year PFS were 59 and 33%, respectively, while 5-year OS was 77.5%. Ki67 was the sole strong independent risk factor for unfavorable outcome according to multivariate analysis, being significantly associated with both PFS and OS. CONCLUSIONS: DP occurred in the majority of patients with advanced jejunoileal NETs, with median PFS being 36 months. Ki67 was a significant predictor of DP and should be considered in determining appropriate treatments and planning follow-up for these patients.

INTRODUCTION: Patients with metastatic or locally advanced, non-resectable, grade 3 poorly differentiated gastroenteropancreatic (GEP) and lung neuroendocrine carcinomas (NECs) are usually treated with in first-line platinum compounds. There is no standard second-line treatment on progression. Accurate biomarkers are needed to facilitate diagnosis and prognostic assessment of patients with NEC. METHODS AND ANALYSIS: The SEcond-line therapy in NEuroendocrine CArcinomas (SENECA) study is a randomised, non-comparative, multicentre phase II trial designed to evaluate the efficacy and safety of folinic acid, 5-fluorouracil and irinotecan (FOLFIRI) or capecitabine plus temozolomide (CAPTEM) regimens after failure of first-line chemotherapy in patients with lung NEC and GEP-NEC. Secondary aims are to correlate the serum miRNA profile and primary mutational status of MEN1, DAXX, ATRX and RB-1 with prognosis and outcome and to investigate the prognostic and predictive role of the Ki-67 score and 18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) or 68Ga-PET/CT. The main eligibility criteria are age ≥18 years; metastatic or locally advanced, non-resectable, grade 3 lung or GEP-NECs; progression to first-line platinum-based chemotherapy. A Bryant and Day design taking into account treatment activity and toxicity was used to estimate the sample size. All analyses will be performed separately for each treatment group in the intention-to-treat population. A total of 112 patients (56/arm) will be randomly assigned (1:1) to receive FOLFIRI every 14 days or CAPTEM every 28 days until disease progression or unacceptable toxicity or for a maximum of 6 months. Patients undergo testing for specific biomarkers in primary tumour tissue and for miRNA in blood samples. MiRNA profiling will be performed in the first 20 patients who agree to participate in the biological substudy. ETHICS AND DISSEMINATION: The SENECA trial, supported by Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori (IRST), was authorised by the locals Ethics Committee and the Italian Medicines Agency (AIFA). Results will be widely disseminated via peer-reviewed manuscripts, conference presentations and reports to relevant authorities.The study is currently open in Italy.

There is scant evidence about optimal management of poorly differentiated neuroendocrine carcinoma of the bladder (BNEC). We performed a multicenter retrospective study on BNEC patients from 13 Italian neuroendocrine-dedicated centers to analyze strategies associated with better outcomes. Mixed adeno-neuroendocrine carcinomas (MANEC) were included. We analyzed overall survival (OS) in the overall cohort, relapse-free survival (RFS) in radically operated patients and progression-free survival (PFS) in patients who received chemotherapy for metastatic disease. Fifty-one BNEC patients were included (male: 46, median age: 70 years). Overall, median OS was 16.0 months, radical tumor resection was performed in 37 patients (72.5%) and 11 of these (29.7%) also received peri-operative platinum-etoposide chemotherapy. Median OS was longer in patients with better performance status (PS) and in those with stage I-III disease at diagnosis compared to stage IV. Among patients who underwent radical tumor resection (N = 37), RFS was longer in patients with better PS and showed a trend towards a longer RFS in those treated with peri-operative chemotherapy than with surgery alone (11 vs. 6 months; p = 0.078). Among 28 patients receiving chemotherapy for metastatic disease, PFS was 5.0 months and there was a trend towards improved PFS in patients receiving carboplatin-etoposide chemotherapy compared to other regimens. A multivariate model unmasked a significant association between carboplatin-etoposide chemotherapy and risk for disease progression or death (HR: 0.39 (95%CI: 0.16-0.96) p = 0.040). Performance status might be associated with improved RFS in radically operated patients, while type of chemotherapy might affect PFS in patients receiving chemotherapy for metastatic BNEC.
RESUMO
We statistically investigate the Coronavirus Disease 19 (COVID-19) pandemic, which became particularly invasive in Italy in March 2020. We show that the high apparent lethality or case fatality ratio (CFR) observed in Italy, as compared with other countries, is likely biased by a strong underestimation of the number of infection cases. To give a more realistic estimate of the lethality of COVID-19, we use the actual (March 2020) estimates of the infection fatality ratio (IFR) of the pandemic based on the minimum observed CFR and analyze data obtained from the Diamond Princess cruise ship, a good representation of a "laboratory" case-study from an isolated system in which all the people have been tested. From such analyses, we derive more realistic estimates of the real extent of the infection as well as more accurate indicators of how fast the infection propagates. We then isolate the dominant factors causing the abnormal severity of the disease in Italy. Finally, we use the death count-the only data estimated to be reliable enough-to predict the total number of people infected and the interval of time when the infection in Italy could end.
RESUMO
Few data are available about sorafenib use in patients with metastatic renal cell carcinoma (mRCC) undergoing hemodialysis. No systematic review has been previously performed about this issue. The objective of the present review is to investigate pharmacokinetics and clinical outcomes of sorafenib in mRCC patients undergoing hemodialysis. According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, all the literature about mRCC dialysis patients receiving sorafenib, published from January 1946 to August 2015, was evaluated. Applying inclusion/exclusion criteria, 11 articles were selected for the analysis; 1 patient from our department was also included. The investigated outcomes were pharmacokinetics, toxicity, response rate, progression-free survival, and overall survival where available. A total of 36 patients were included. Median treatment duration was 6.0 months on overall population; median progression-free survival was 6.3 months (calculated on 19 patients); response rate was 22% (on 29 patients); median overall survival was 14.9 months (on 28 patients). Of note, 24 patients started sorafenib at reduced dose; 6 of 36 patients (17%) required dose reduction due to adverse events (AEs). Sorafenib treatment was discontinued in 7 patients (19%) because of AEs. Most of AEs were Grade 1-2; severe toxicities (Grade 4-5) included G4 anemia (1 case), G4 hypertension (1 case), G4 cerebellar hemorrhage (1 patient), and a case of G5 subarachnoid hemorrhage. This review confirmed the efficacy of sorafenib treatment in mRCC patients receiving hemodialysis. Nevertheless, drug toxicity seems to be increased in these patients, despite the initiation of therapy at reduced doses; therefore, sorafenib should be used with caution in dialysis patients.

The colon is a very rare metastatic localization. Here we report a case of colonic metastases from gastric adenocarcinoma whose clinical presentation was suggestive of a de novo adenocarcinoma of the ascending colon. The authors discuss that in the presence of a previous history of gastric cancer, immunohistochemical analysis on endoscopic biopsies may help in the definition of a differential diagnosis. Furthermore, this rare metastatic localization might suggest a poor prognosis and a more accurate diagnostic work-up.
RESUMO
PURPOSE: Second-line chemotherapy in patients with metastatic gastric cancer (MGC) pre-treated with cisplatin is not a standard option. We studied a combination of irinotecan, fluorouracil and folates. METHODS: Patients progressive to cisplatin-based chemotherapy were enrolled. Irinotecan 180 mg/m(2), folinic acid 200 mg/m(2), and fluorouracil 400 mg/m(2) were given on day 1, immediately followed by fluorouracil 2,400 mg/m(2) 46 h continuous infusion (simplified FOLFIRI), every 2 weeks. RESULTS: Between June 2002 and May 2003, 28 patients were treated. Median age was 57 years (range 38-68). Most patients had a distal primary (90%), and metastatic disease (71%). Partial response was obtained in six patients (21%, 95% CI 8-41) and stable disease in eight (21%, 95% CI 13-41). Among the six responsive patients three were refractory to docetaxel. At a median follow-up of 2.9 years median time to progression was 4 months (95% CI: 2-5), and median overall survival was 5 months (95% CI 4-9). Toxicity was mild, without treatment-related deaths or life-treating adverse events. CONCLUSIONS: Simplified FOLFIRI was moderately active and well tolerated in unselected patients with MGC pre-treated with cisplatin-based chemotherapy. Its role in patients refractory to taxanes is promising and warrants further investigation.
