RESUMO

Pretransplant malignancy unrelated to hepatocellular carcinoma is a challenging condition in liver transplantation. Standard of care requires the completion of treatments and a disease-free period before the transplant. However, in the setting of a fulminant hepatic failure, these steps cannot be achieved. A 46-year-old woman with a recent diagnosis of stage 2 breast cancer presented to our center with a fulminant hepatic failure of unknown origin. Because of the rapid worsening of her clinical status, she was listed as eligible for transplant after a multidisciplinary evaluation. Because of a shortage of available donors, a deceased donor ABO-incompatible liver transplant with a synchronous mastectomy and first-level axillary lymphadenectomy was performed. To prevent antibody-mediated rejection, a triple immunosuppression therapy and a postoperative therapeutic plasmapheresis were performed. The patient remains without cancer recurrence at 18 months of follow-up. Recent studies have shown that cancer recurrence in recipients with pretransplant malignancy is considerably lower than suggested in previously published studies. However,this data is not sufficient to establish evidence-based guidelines on the indications and timing of transplant. In selected cases, the presence of a pretransplant malignancy does notrepresent a contraindication for a rescue liver transplant. Further studies are needed to stratify the risk and to help clinicians to choose the best strategy in an urgent context such as this.

RESUMO

BACKGROUND: Second- or third-line treatment options for metastatic renal cell carcinoma (mRCC) have dramatically changed in the last few years. There are no criteria for the choice between nivolumab and cabozantinib, which both demonstrated overall survival (OS) gain in pivotal trials. OBJECTIVE: We conducted an analysis of oncological outcomes in patients treated in the Veneto Region (Italy), studying different sequences of TKI-nivolumab-cabozantinib or TKI-cabozantinib-nivolumab in a publicly funded healthcare system. PATIENTS AND METHODS: We conducted a retrospective, real-world analysis of all consecutive patients with mRCC treated with nivolumab or cabozantinib in 2017-2018 at 19 Oncology Units in the Veneto Region. RESULTS: We identified 170 patients, 73 % males, median age 68.4 years. All patients started second-line treatment, 59 % received a third-line therapy. Patients with NLR > 3 had a shorter OS (p < 0.0001). In the second-line treatment, nivolumab was administered to 108 patients (63 %), cabozantinib to 29 (17 %); in the third-line treatment nivolumab was administered to 42 patients (25 %), cabozantinib to 49 (29 %). Median OS and PFS in second line treatment were 28.4 and 6.6 months for nivolumab, 16.8 and 6.6 months for cabozantinib. Median OS and PFS in third-line treatment were 27 and 5.2 months for nivolumab, 16.6 and 7.5 months for cabozantinib. Median OS for nivolumab>cabozantinib sequence versus cabozantinib > nivolumab was 28.8 versus 19.9 months (p = 0.2); median PFS for both the sequences were similar at 5.7 months. A cost effectiveness per month of survival of the two sequences analysis was performed: the cost per month for the nivolumab > cabozantinib sequence was 1738.60whereas the cost for the other one was €1624.80. CONCLUSIONS: In our real-world cohort, most patients received nivolumab as second-line treatment. Outcomes of single drugs are superimposable with those in the published literature. Both the sequences of nivolumab and cabozantinib appear to be viable, effective strategies from an OS and cost-effective perspective.

RESUMO

INTRODUCTION: Coronavirus disease 2019 (COVID-19) pandemic started in Italy with clusters identified in Northern Italy. The Veneto Oncology Network (Rete Oncologica Veneta) licenced dedicated guidelines to ensure proper care minimising the risk of infection in patients with cancer. Rete Oncologica Veneta covID19 (ROVID) is a regional registry aimed at describing epidemiology and clinical course of Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with cancer. MATERIALS AND METHODS: Patients with cancer diagnosis and documented SARS-CoV-2 infection are eligible. Data on cancer diagnosis, comorbidities, anticancer treatments, as well as details on SARS-CoV-2 infection (hospitalisation, treatments, fate of the infection), have been recorded. Logistic regression analysis was applied to calculate the association between clinical/laboratory variables and death from any cause. RESULTS: One hundred seventy patients have been enrolled. The median age at time of the SARS-CoV infection was 70 years (25-92). The most common cancer type was breast cancer (n = 40). The majority of the patients had stage IV disease. Half of the patients had two or more comorbidities. The majority of the patients (78%) presented with COVID-19 symptoms. More than 77% of the patients were hospitalized and 6% were admitted to intensive care units. Overall, 104 patients have documented resolution of the infection. Fifty-seven patients (33%) have died. In 29 cases (17%), the cause of death was directly correlated to SARS-CoV-2 infection. Factors significantly correlated with the risk of death were the following: Eastern Cooperative Oncology Group performance status (PS), age, presence of two or more comorbidities, presence of dyspnoea, COVID-19 phenotype ≥ 3, hospitalisation, intensive care unit admission, neutrophil/lymphocyte ratio and thrombocytopenia. CONCLUSIONS: The mortality rate reported in this confirms the frailty of this population. These data reinforce the need to protect patients with cancer from SARS-CoV-2 infection.

RESUMO

BACKGROUND: Recent data suggest a potential activity and a good tolerability of capecitabine in advanced hepatocellular carcinoma (HCC). AIMS: To evaluate capecitabine activity and safety in a wide cohort of advanced HCC patients. METHODS: Retrospective analysis of 143 capecitabine-treated patients (January 2010 to December 2017) in three centers of the Veneto Oncology Network. RESULTS: Capecitabine was administered in second and third line, but also in first line instead of sorafenib in Child-Pugh B patients (70%), compromised clinical conditions (14%) or contraindications to antiangiogenetics (16%). Median overall survival (OS) and time to progression (TTP) were 6.9 and 2.8 months, respectively. There were no differences in OS and TTP between the 32 patients treated with non-metronomic scheme (2000 mg/day for 14 days) and the 111 patients treated with metronomic scheme (1000 mg/day) after correction for prognostic factors at baseline with a propensity score analysis. Capecitabine was more active in patients intolerant to sorafenib than in those progressing during treatment (p = 0.024). At least one adverse event (mainly hematological) was experienced by 73% of patients but discontinuation was necessary only in 11 (8%). CONCLUSIONS: Capecitabine can be considered an active and safe option in advanced HCC, especially for patients unfit for other treatments.

RESUMO

BACKGROUND: Post-hoc analyses of AFP response and progression and their relationship with objective measures of response and survival were performed in patients from REACH. METHODS: Serum AFP was measured at baseline and every 3 cycles (2 weeks/cycle). Associations between AFP and radiographic progression and efficacy end points were analysed. RESULTS: Median percent AFP increase from baseline was smaller in the ramucirumab than in the placebo arm throughout treatment. Time to AFP progression (HR 0.621; P < 0.0001) and to radiographic progression (HR 0.613; P < 0.0001) favoured ramucirumab. Association between AFP and radiographic progression was shown at 6 (OR 6.44, 95% CI 4.03, 10.29; P < 0.0001) and 12 weeks (OR 2.28, 95% CI 1.47, 3.53; P = 0.0002). AFP response was higher with ramucirumab compared with placebo (P < 0.0001). More patients in the ramucirumab arm experienced tumour shrinkage and AFP response compared with placebo. Survival was longer in patients with AFP response (13.6 months) than in patients without (6.2 months), irrespective of treatment (HR 0.457, P < 0.0001). CONCLUSIONS: Treatment with ramucirumab prolonged time to AFP progression, slowed AFP increase and was more likely to induce AFP response. Similar benefits in radiographic progression and response correlated with AFP changes.

RESUMO

BACKGROUND: Tivantinib (ARQ 197), a selective, oral MET inhibitor, improved overall survival and progression-free survival compared with placebo in a randomised phase 2 study in patients with high MET expression (MET-high) hepatocellular carcinoma previously treated with sorafenib. The aim of this phase 3 study was to confirm the results of the phase 2 trial. METHODS: We did a phase 3, randomised, double-blind, placebo-controlled study in 90 centres in Australia, the Americas, Europe, and New Zealand. Eligible patients were 18 years or older and had unresectable, histologically confirmed, hepatocellular carcinoma, an Eastern Cooperative Oncology Group performance status of 0-1, high MET expression (MET-high; staining intensity score ≥2 in ≥50% of tumour cells), Child-Pugh A cirrhosis, and radiographically-confirmed disease progression after receiving sorafenib-containing systemic therapy. We randomly assigned patients (2:1) in block sizes of three using a computer-generated randomisation sequence to receive oral tivantinib (120 mg twice daily) or placebo (twice daily); patients were stratified by vascular invasion, extrahepatic spread, and α-fetoprotein concentrations (≤200 ng/mL or >200 ng/mL). The primary endpoint was overall survival in the intention-to-treat population. Efficacy analyses were by intention to treat and safety analyses were done in all patients who received any amount of study drug. This study is registered with ClinicalTrials.gov, number NCT01755767. FINDINGS: Between Dec 27, 2012, and Dec 10, 2015, 340 patients were randomly assigned to receive tivantinib (n=226) or placebo (n=114). At a median follow-up of 18·1 months (IQR 14·1-23·1), median overall survival was 8·4 months (95% CI 6·8-10·0) in the tivantinib group and 9·1 months (7·3-10·4) in the placebo group (hazard ratio 0·97; 95% CI 0·75-1·25; p=0·81). Grade 3 or worse treatment-emergent adverse events occurred in 125 (56%) of 225 patients in the tivantinib group and in 63 (55%) of 114 patients in the placebo group, with the most common being ascites (16 [7%] patients]), anaemia (11 [5%] patients), abdominal pain (nine [4%] patients), and neutropenia (nine [4%] patients) in the tivantinib group. 50 (22%) of 226 patients in the tivantinib group and 18 (16%) of 114 patients in the placebo group died within 30 days of the last dose of study medication, and general deterioration (eight [4%] patients) and hepatic failure (four [2%] patients) were the most common causes of death in the tivantinib group. Three (1%) of 225 patients in the tivantinib group died from a treatment-related adverse event (one sepsis, one anaemia and acute renal failure, and one acute coronary syndrome). INTERPRETATION: Tivantinib did not improve overall survival compared with placebo in patients with MET-high advanced hepatocellular carcinoma previously treated with sorafenib. Although this METIV-HCC trial was negative, the study shows the feasibility of doing integral tissue biomarker studies in patients with advanced hepatocellular carcinoma. Additional randomised studies are needed to establish whether MET inhibition could be a potential therapy for some subsets of patients with advanced hepatocellular carcinoma.

RESUMO

A large body of biomedical evidence indicates that activation of Nrf2 by curcumin increases the nucleophilic tone and damps inflammation cumulatively supporting the malignant phenotype. Conversely, genetic analyses suggest a possible oncogenic nature of constitutive Nrf2 activation since an increased nucleophilic tone is alleged increasing chemoresistance of cancer cells. Aiming to contribute to solve this paradox, this study addressed the issue of safety and efficacy of curcumin as complementary therapy of gemcitabine on pancreatic cancer. This was a single centre, single arm prospective phase II trial. Patients received gemcitabine and Meriva®, a patented preparation of curcumin complexed with phospholipids. Primary endpoint was response rate, secondary endpoints were progression free survival, overall survival, tolerability and quality of life. Analysis of inflammatory biomarkers was also carried out. Fifty-two consecutive patients were enrolled. Forty-four (13 locally advanced and 31 metastatic) were suitable for primary endpoint evaluation. Median age was 66 years (range 42-87); 42 patients had Eastern Cooperative Oncology Group performance status 0-1. The median number of treatment cycle was 4.5 (range 2-14). We observed 27.3% of response rate and 34.1% of cases with stable disease, totalizing a disease control rate of 61.4%. The median progression free survival and overall survival were 8.4 and 10.2 months, respectively. Higher IL-6 and sCD40L levels before treatment were associated to a worse overall survival (p < 0.01). Increases in sCD40L levels after 1 cycle of chemotherapy were associated with a reduced response to the therapy. Grade 3/4 toxicity was observed (neutropenia, 38.6%; anemia, 6.8%). There were no significant changes in quality of life during therapy. In conclusion, the complementary therapy to gemcitabine with phytosome complex of curcumin is not only safe but also efficiently translate in a good response rate in first line therapy of advanced pancreatic cancer.

RESUMO

PURPOSE: To report patient-focused outcomes as measured by quality of life (QoL) and performance status (PS) in REACH, a phase III placebo-controlled randomised study, assessing ramucirumab in advanced hepatocellular carcinoma (HCC) patients who received prior sorafenib. METHODS: Eligible patients had advanced HCC, Child-Pugh A, PS 0 or 1 and prior sorafenib. Patients received ramucirumab (8 mg/kg) or placebo (1:1) on day 1 of a 2-week cycle. QoL was assessed by FACT Hepatobiliary Symptom Index (FHSI)-8 and EuroQoL (EQ-5D) at baseline; cycles 4, 10, and 16; and end of treatment. PS was assessed at baseline, each cycle, and end of treatment. Deterioration in FHSI-8 was defined as a ≥3-point decrease from baseline and PS deterioration was defined as a change of ≥2. Both intention-to-treat and pre-specified subgroup of patients with baseline serum alpha-fetoprotein (AFP) ≥400 ng/mL were assessed. RESULTS: There were 565 patients randomised to ramucirumab and placebo. Compliance with FHSI and EQ-5D was high and similar between groups. In the ITT population, deterioration in FHSI-8, EQ-5D, and PS was similar between ramucirumab and placebo. In patients with baseline AFP ≥400 ng/mL, ramucirumab significantly reduced deterioration in FHSI-8 at the end of treatment compared with placebo (P = 0.0381), and there was a trend towards a delay in the deterioration of symptoms in FHSI-8 (HR 0.690; P = 0.054) and PS (HR 0.642; P = 0.057) in favour of ramucirumab. CONCLUSIONS: We report one of the most comprehensive data sets of QoL and symptom burden in patients undergoing systemic therapy for advanced HCC. Ramucirumab was associated with no worsening of QoL. In patients with baseline AFP ≥400 ng/mL, the significant survival benefit observed in patients treated with ramucirumab was coupled with a trend in patient-focused outcome benefits. CLINICAL TRIAL REGISTRATION: NCT01140347.

RESUMO

Tumor biopsies may help to reliably distinguish hepatocellular carcinoma (HCC) from other tumors, mostly cholangiocarcinoma as well as to identify the patient populations who most benefit from target-driven HCC treatments, in order to improve the success rate of experimental therapies. Clarifying tumor biology may also lead to identify biomarkers with prognostic role and/or enabling to predict response or resistance to therapies. Recently, clinical trials have more efficiently included biomarker endpoints and increasingly collected tumor tissue from enrolled patients. Due to their frail status and sometimes fast-progressing disease, the performance status of patients with HCC progressing on first-line therapy can deteriorate quickly, preventing their enrollment in clinical trials. However, the challenge of identifying the proper patient at the proper time can be overcome by periodic inter-department meetings involving the key specialists taking care of HCC patients, and solid networks between research centers and referring institutions. An early planned biopsy would also facilitate timely inclusion of patients in biology-driven clinical trials. Ultimately, institution of multidisciplinary teams can optimize treatment choice, biopsy timing, and quick enrollment of patients in clinical trials, before their performance status deteriorates.

RESUMO

AIM: We investigated the behavior of circulating endothelial cells (CEC) in patients with hepatocellular carcinoma (HCC) receiving sorafenib, and whether CEC levels were associated with time to progression (TTP). MATERIALS & METHODS: CECs in advanced HCC patients receiving sorafenib were counted at baseline and every 4 weeks. RESULTS: Twenty four HCC patients were enrolled in the study. Median TTP was 3.2 months (1-6). Median baseline CEC levels were 67 cells/ml, with an increase of 169.8% after 4 weeks of treatment. Any time CEC levels in patients with a TTP lower than 4 months were higher, but not statistically significant, compared with those in patients with TTP more than 4 months. CONCLUSION: Treatment with sorafenib changed CEC levels in HCC patients.

RESUMO

INTRODUCTION: Bone metastases affect the majority of patients with castration-resistant prostate cancer (CRPC), resulting in significant morbidity and mortality. This review describes the current therapies available for the management of CRPC patients with bone metastases. Areas covered: Studies on the use of currently available therapeutic approaches for palliating pain, delaying skeletal-related events (SREs) and prolonging survival in CRPC patients with bone metastases have been examined. PubMed database was searched in May 2016 starting with the following keywords: ('castration-resistant prostate cancer' OR 'CRPC') AND 'bone metastases', and approximately 270 results were retrieved. More specific searches were then performed on the epidemiology and molecular pathogenesis (in particular, 'vicious cycle' was used as a keyword), the management of pain, SREs and survival. The following keywords were also used individually: abiraterone, cabazitaxel, denosumab, docetaxel, enzalutamide, radium-223, sipuleucel-T, samarium-153, strontium-89, zoledronate. Randomized-controlled trials, observational studies, reviews, systematic reviews and meta-analyses were selected and articles were excluded if not in English. Expert commentary: Currently, clear recommendations on the optimal use of the agents available to treat mCRPC are lacking. Therefore, to ensure patients the best treatment, both their clinical characteristics and the features of each product have to be considered.

RESUMO

Cetuximab is a monoclonal antibody that competitively inhibits the epidermal growth factor receptor (EGFR). It is used for the treatment of metastatic colorectal cancer after first-line therapy. We report the first case of a pustular psoriasiform drug eruption induced by cetuximab in a patient with colorectal cancer. This paradoxical side effect could be the result of an imbalance in downstream molecular pathways due to the EGFR signal blockade that could, in selected patients, induce alternative signalling pathways related to keratinocyte proliferation.

RESUMO

The aim of the present study was to determine the outcome of patients undergoing pancreatic resection with (VR+) or without (VR-) mesenteric-portal vein resection for pancreatic carcinoma. Between January 1998 and December 2012, 241 patients with pancreatic cancer underwent pancreatic resection: in 64 patients, surgery included venous resection for macroscopic invasion of mesenteric-portal vein axis. Morbidity and mortality did not differ between the two groups (VR+: 29% and 3%; VR-: 30% and 4.0%, resp.). Radical resection was achieved in 55/64 (78%) in the VR+ group and in 126/177 (71%) in the VR- group. Vascular invasion was histologically proven in 44 (69%) of the VR+ group. Survival curves were not statistically different between the two groups. Mean and median survival time were 26 and 15 months, respectively, in VR- versus 20 and 14 months, respectively, in VR+ group (p = 0.52). In the VR+ group, only histologically proven vascular invasion significantly impacted survival (p = 0.02), while, in the VR- group, R0 resection (p = 0.001) and tumor's grading (p = 0.01) significantly influenced long-term survival. Vascular resection during pancreatectomy can be performed safely, with acceptable morbidity and mortality. Long-term survival was the same, with or without venous resection. Survival was worse for patients with histologically confirmed vascular infiltration.

RESUMO

The most common cause of hyperinsulinaemic hypoglycaemia in adult is insulinoma. Although nesidioblastosis is a rare but well-recognized disorder of persistent hypoglycaemia in infants, it is extremely rare in adults.We present a case of a 59-year-old woman with small neuroendocrine tumour of the tail of the pancreas, diagnosed by CT scans and MRI, and hypoglycaemic syndrome. Laparoscopic distal pancreatectomy was performed, and pathologic examination showed a well-differentiated, non-functioning endocrine tumour of the pancreas and diffuse nesidioblastosis in the remnant gland. In the early postoperative period, recurrent hypoglycaemia occurred in spite of oral diazoxide therapy. Plasma proinsulin levels were extremely high. 18F-DOPA positron emission tomography showed a pathologic uptake of tracer in the head and the uncinate process of the pancreas. Subtotal pancreatectomy was suggested but the patient refused operation: she is taking diazoxide 100 mg three times daily. Coexistence of nesidioblastosis with a neuroendocrine tumour makes preoperative diagnosis and management of severe hypoglycaemia more difficult. Nesidioblastosis should be considered in differential diagnosis of hypoglycaemic syndrome, but histological examination is necessary for a definitive tissue diagnosis.

RESUMO

AIM: To confirm the efficacy and safety of bevacizumab/XELOX combination for the treatment of locally advanced or metastatic colorectal cancer (CRC) in Italy. METHODS: This multicentric, prospective, open-label study included patients with CRC previously untreated with chemotherapy. Patients were administered bevacizumab in combination with XELOX. The primary efficacy end-point was progression-free survival (PFS). Secondary end-points included time to overall response (TOR), duration of response (DOR), time to treatment failure (TTF) and overall survival (OS). The incidence and type of adverse events AEs and severe AEs were evaluated. Also, the mutational status of BRAF and KRAS was assessed by high resolution melting and direct sequencing, and quality of life (QoL) was measured by the EuroQoL EQ-5D questionnaire at baseline and at the last visit. RESULTS: The intention-to-treat population included 197 patients (mean age: 62.3 ± 9.9 years, 56.4% males). At baseline, 16/34 evaluable subjects (47.1%) harbored a KRAS and/or a BRAF mutation; the mean QoL index was 80.2 ± 14.3. First-line therapy was given for 223.7 ± 175.9 d, and after a mean follow-up of 387.7 ± 238.8 d all patients discontinued from the study mainly for disease progression (PD, 45.4%) and AEs (25.4%). Median PFS was 9.7 mo (95%CI: 8.4-10.5) and the median values for secondary end-points were: TOR = 3.9 mo (95%CI: 2.6-4.7), DOR = 8.5 mo (95%CI: 7.3-10.3), TTF = 6.7 mo (95%CI: 6.0-7.7) and OS = 23.2 mo (95%CI: 20.1-27.2). Patients carrying at least one lesion had a lower overall response rate (66.7% vs 88.9%) and a lower probability of achieving complete or partial response than those without mutations, but the difference in relative risk was not statistically significant (P = 0.2). Mean EQ-5D-3L raw index score significantly decreased to 74.9 ± 19.1 at the last visit (signed-rank test, P = 0.0076), but in general the evaluation on QoL perceived by patients was good. CONCLUSION: The efficacy of bevacizumab in combination with XELOX in terms of PFS in patients with aCRC or mCRC in Italy was confirmed, with acceptable toxicity.

RESUMO

BACKGROUND: VEGF and VEGF receptor-2-mediated angiogenesis contribute to hepatocellular carcinoma pathogenesis. Ramucirumab is a recombinant IgG1 monoclonal antibody and VEGF receptor-2 antagonist. We aimed to assess the safety and efficacy of ramucirumab in advanced hepatocellular carcinoma following first-line therapy with sorafenib. METHODS: In this randomised, placebo-controlled, double-blind, multicentre, phase 3 trial (REACH), patients were enrolled from 154 centres in 27 countries. Eligible patients were aged 18 years or older, had hepatocellular carcinoma with Barcelona Clinic Liver Cancer stage C disease or stage B disease that was refractory or not amenable to locoregional therapy, had Child-Pugh A liver disease, an Eastern Cooperative Oncology Group performance status of 0 or 1, had previously received sorafenib (stopped because of progression or intolerance), and had adequate haematological and biochemical parameters. Patients were randomly assigned (1:1) to receive intravenous ramucirumab (8 mg/kg) or placebo every 2 weeks, plus best supportive care, until disease progression, unacceptable toxicity, or death. Randomisation was stratified by geographic region and cause of liver disease with a stratified permuted block method. Patients, medical staff, investigators, and the funder were masked to treatment assignment. The primary endpoint was overall survival in the intention-to-treat population. This study is registered with ClinicalTrials.gov, number NCT01140347. FINDINGS: Between Nov 4, 2010, and April 18, 2013, 565 patients were enrolled, of whom 283 were assigned to ramucirumab and 282 were assigned to placebo. Median overall survival for the ramucirumab group was 9·2 months (95% CI 8·0-10·6) versus 7·6 months (6·0-9·3) for the placebo group (HR 0·87 [95% CI 0·72-1·05]; p=0·14). Grade 3 or greater adverse events occurring in 5% or more of patients in either treatment group were ascites (13 [5%] of 277 patients treated with ramucirumab vs 11 [4%] of 276 patients treated with placebo), hypertension (34 [12%] vs ten [4%]), asthenia (14 [5%] vs five [2%]), malignant neoplasm progression (18 [6%] vs 11 [4%]), increased aspartate aminotransferase concentration (15 [5%] vs 23 [8%]), thrombocytopenia (13 [5%] vs one [<1%]), hyperbilirubinaemia (three [1%] vs 13 [5%]), and increased blood bilirubin (five [2%] vs 14 [5%]). The most frequently reported (≥1%) treatment-emergent serious adverse event of any grade or grade 3 or more was malignant neoplasm progression. INTERPRETATION: Second-line treatment with ramucirumab did not significantly improve survival over placebo in patients with advanced hepatocellular carcinoma. No new safety signals were noted in eligible patients and the safety profile is manageable. FUNDING: Eli Lilly and Co.

RESUMO

Bone is a common site for tumor spread in patients with solid tumors. So far bisphosphonates have been the main pharmacological treatment option for patients with bone metastases. We present a case of bone metastatic gastric cancer treated with zoledronic acid at first and later with denosumab. After 1 year of denosumab treatment, the 18F-fluorodeoxyglucose (18F-FDG)-PET/computed tomography scan reassessment documented a metabolic complete response, even in the absence of specific antiblastic treatment. Whether denosumab can be used directly after pretreatment with bisphosphonates has yet to be addressed.

RESUMO

Everolimus is a valid therapeutic option for neuroendocrine tumors (NETs); however, data in a real-world setting outside regulatory trials are sparse. The aim of this study was to determine everolimus tolerability and efficacy, in relation to previous treatments, in a compassionate use program. A total of 169 patients with advanced progressive NETs treated with everolimus were enrolled, including 85 with pancreatic NETs (pNETs) and 84 with nonpancreatic NETs (non-pNETs). Previous treatments included somatostatin analogs (92.9%), peptide receptor radionuclide therapy (PRRT; 50.3%), chemotherapy (49.7%), and PRRT and chemotherapy (22.8%). Overall, 85.2% of patients experienced adverse events (AEs), which were severe (grade 3-4) in 46.1%. The most frequent severe AEs were pneumonitis (8.3%), thrombocytopenia (7.7%), anemia (5.3%), and renal failure (3.5%). In patients previously treated with PRRT and chemotherapy, a 12-fold increased risk for severe toxicity was observed, with grade 3-4 AEs reported in 86.8% (vs. 34.3% in other patients). In addition, 63.3% of patients required temporarily everolimus discontinuation due to toxicity. Overall, 27.8% of patients died during a median follow-up of 12 months. Median progression-free survival (PFS) and overall survival (OS) were 12 months and 32 months, respectively. Similar disease control rates, PFS, and OS were reported in pNETs and non-pNETs. In the real-world setting, everolimus is safe and effective for the treatment of NETs of different origins. Higher severe toxicity occurred in patients previously treated with systemic chemotherapy and PRRT. This finding prompts caution when using this drug in pretreated patients and raises the issue of planning for everolimus before PRRT and chemotherapy in the therapeutic algorithm for advanced NETs.
