RESUMO

BACKGROUND: The non-inferiority of dexamethasone (DEX) on day 1, with or without low-dose DEX on days 2 and 3, combined with oral NEPA (netupitant/palonosetron), compared with the guideline-consistent use of DEX was demonstrated in cisplatin. Here, we complete the analysis by assessing the impact of emesis on daily lives of patients receiving DEX-sparing regimens using the Functional Living Index-Emesis (FLIE). METHODS: Chemotherapy-naïve patients undergoing cisplatin (≥70 mg/m2), were given NEPA and DEX (12 mg) on day 1 and randomized to receive either 1) no further DEX (DEX1), 2) oral DEX (4 mg daily) on days 2-3 (DEX3), or 3) DEX (4 mg twice daily) on days 2-4 (DEX4; control). Patients completed the FLIE questionnaire on day 6 of cycle 1. Endpoints included the FLIE nausea domain, vomiting domain, and overall combined domain scores, as well as the proportion of patients with no impact on daily life (NIDL; overall score > 108). This was a protocol-planned analysis. RESULTS: In the DEX1 group, no significant differences were observed in the FLIE nausea score (48.9 [±1.8; SE] vs. 53.7 [±1.5]), vomiting score (56.6 [±1.4] vs. 58.7 [±0.8]) and overall score (105.6 [±2.8] vs.112.4 [±1.9]) versus DEX4 control; similar results were observed in the DEX3 group for nausea score (49.6 [±1.7]), vomiting score (58.2 [±1]) and overall score (107.8 [±2.4]) versus control. There were no significant between-group differences in the proportion of patients reporting NIDL. CONCLUSION: Reducing DEX, when administered with NEPA, does not seem to adversely impact the daily functioning in patients undergoing cisplatin. TRIAL REGISTRATION: ClinicalTrials.gov NCT04201769 .

RESUMO

Stage I-III triple-negative breast cancer accounts for approximately 15-20% of new diagnoses of early breast cancer. Novel systemic treatment options have recently been assessed as part of the neoadjuvant approach, such as the addition of immune checkpoint inhibitors to cytotoxic chemotherapy. However, several questions remain unanswered, including the identification of predictors of response to immunotherapy in this setting, and further efforts aimed at identifying reliable predictors and clarifying the effective role of PD-L1 status, tumor mutational burden, tumor-infiltrating lymphocytes and other biomarkers are warranted. Herein we will provide an overview of recent clinical studies of neoadjuvant immune checkpoint inhibitors in patients with triple-negative breast cancer, especially focusing on the recently presented and published KEYNOTE-522, IMpassion031 and GeparNUEVO trials.

RESUMO

BACKGROUND: To reduce the overall exposure to dexamethasone (DEX) in patients receiving cisplatin-based chemotherapy, we evaluated the noninferiority of DEX on day 1, with or without low-dose DEX on days 2 and 3, combined with an oral fixed-dose combination of netupitant and palonosetron (NEPA), compared with the guideline-consistent use of 4-day DEX. PATIENTS AND METHODS: In this open-label, multicenter study, chemotherapy-naïve patients undergoing high-dose cisplatin (≥70 mg/m2 ), were given NEPA and DEX (12 mg) on day 1 and randomized (1:1:1 ratio) to receive either (a) no further DEX (DEX1), (b) oral DEX (4 mg daily) on days 2-3 (DEX3), or (c) DEX (4 mg twice daily) on days 2-4 (DEX4). The primary efficacy endpoint was complete response (CR: no emesis and no rescue medication) during the 5-day overall phase. The noninferiority margin was set at -15% difference (DEX1 or DEX3 minus DEX4). Secondary efficacy endpoints included complete protection (CP: CR and none or mild nausea). RESULTS: Two-hundred twenty-eight patients, 76 in each arm, were assessable. Noninferiority was met for both DEX-sparing regimens and the reference arm, with overall phase CR rates of 76.3% in each of the DEX1 and DEX3 arms and 75.0% in the DEX4 arm (95% confidence interval, -12.3% to 15% for each comparison). During the overall phase, CP rates were similar between groups. CONCLUSION: A simplified regimen of NEPA plus single-dose DEX offers comparable chemotherapy-induced nausea and vomiting prevention throughout 5 days post-chemotherapy with the advantage of sparing patients additional doses of DEX in the high-emetic-risk setting of cisplatin-based chemotherapy. IMPLICATIONS FOR PRACTICE: Dexamethasone (DEX) has traditionally played an integral role in the management of chemotherapy-induced emesis. Although generally considered safe, even short-term DEX use is associated with various side effects, and some evidence suggests that concurrent steroids may reduce the efficacy of immunotherapies. This study demonstrates comparable antiemetic control during the 5 days post-chemotherapy with a simplified regimen of netupitant/palonosetron plus single-dose DEX versus the standard 4-day DEX reference treatment in high-dose cisplatin. This represents a clinically relevant achievement as it not only simplifies antiemetic prophylaxis but also offers an opportunity to appropriately use in patients where caution with corticosteroid use is advised.

RESUMO

We demonstrated the non-inferiority of a dexamethasone (DEX)-sparing (single-dose) regimen with NEPA, a netupitant/palonosetron fixed combination, for preventing chemotherapy-induced nausea and vomiting (CINV) caused by cisplatin. This pre-planned exploratory analysis assessed the effect of the DEX-sparing regimen on a patient's food intake. Chemotherapy-naïve patients undergoing cisplatin (≥ 70 mg/m2) were given NEPA and DEX (12 mg) on day 1 and randomized to receive either no further DEX (DEX1), or oral DEX (4 mg BID) on days 2-4 (DEX4). Patient-reported endpoint maintenance of usual daily food intake was assessed during the 5-days post-chemotherapy. The relationship between usual daily food intake and CINV control, pre-chemotherapy self-rated food intake and BMI-adjusted weight loss (WL) were evaluated. One-hundred fifty-two patients (76/group) were assessable. The proportion of patients reporting maintenance of usual daily food intake was similar in both groups: 69.7% (95% CI, 58.6-78.9) for DEX1 vs. 72.4% (95% CI, 61.4-81.2) for DEX4. Only CINV control was significantly associated with maintenance of usual daily food intake (P ≤ 0.001) during the overall phase. The DEX-sparing regimen does not adversely affect patient-reported daily food intake post-chemotherapy. The current analysis adds further insights into antiemetic efficacy of DEX sparing beyond day 1 in the challenging setting of cisplatin.Trial registration: The parent study was registered on ClinicalTrials.gov (NCT04201769).

RESUMO

BACKGROUND: The 2021 has seen the publication of two practice-changing trials on second-line fluoropyrimidine-based doublet chemotherapy for advanced biliary tract cancer (BTC) patients. Herein, we conducted a meta-analysis aimed at assessing the overall survival (OS), disease control rate (DCR), and overall response rate (ORR) in ABC-06 and NIFTY trials. METHODS: We retrieved all the relevant trials through PubMed/Medline, Cochrane library, and EMBASE; additionally, proceedings of the main international oncological meetings were also searched for relevant abstracts. Outcomes of interest included OS, DCR, and ORR. Hazard Ratios (HRs) and their 95% Confidence Intervals (CIs) for OS, and Odds Ratios (ORs) and 95% CIs for DCR and ORR, were extracted. RESULTS: According to our results, fluoropyrimidine-based doublet chemotherapy significantly decreased the risk of death (HR, 0.63; 95% CI, 0.49-0.8) compared with control treatment. In addition, higher DCR and ORR were observed in BTC patients receiving fluoropyrimidine-based combinations. CONCLUSIONS: Although ABC-06 and NIFTY have recently established fluoropyrimidine-based doublet chemotherapy as the standard of care, the role of second-line chemotherapy remains the object of debate in the BTC medical community. Further studies are required to clarify the role of second-line fluoropyrimidine-based chemotherapy in some 'neglected' populations, including BTC patients with poor ECOG-PS.

RESUMO

(1) Background: In recent years, immunotherapy has revolutionized the treatment landscape of non-small cell lung cancer (NSCLC), representing a therapeutic breakthrough in this field. Antacid agents such as proton pump inhibitors (PPIs) and histamine-2-receptor antagonists (H2RAs) are commonly prescribed for extended periods in NSCLC patients, and these drugs have the potential to modify the efficacy of immune checkpoint inhibitors (ICIs). (2) Materials and Methods: Herein, we conducted a systematic review and meta-analysis to investigate the impact of PPIs and H2RAs on progression-free survival (PFS) and overall survival (OS) among patients receiving immunotherapy for metastatic NSCLC. Effect measures for OS were Hazard Ratios (HRs) and 95% Confidence Intervals (CIs), which were extracted from available studies. Forest plots were used to assess HRs to describe the relationship between treatment and OS in the specified cohorts of patients. (3) Results: Six studies were included in the analysis, involving 2267 patients. The pooled HRs for OS and PFS were 1.4 (95% CI, 1.25-1.58) and 1.29 (95% CI, 1.17-1.43), respectively, suggesting that PPIs and H2RAs administration was negatively associated with PFS and OS. (4) Conclusion: Concomitant antacid use could modify the activity of ICIs in NSCLC patients.

RESUMO

PURPOSE: We performed this phase III study to compare the irinotecan, leucovorin (LV), and fluorouracil (FU) regimen (FOLFIRI) versus the oxaliplatin, LV, and FU regimen (FOLFOX4) in previously untreated patients with advanced colorectal cancer. PATIENTS AND METHODS: A total of 360 chemotherapy-naive patients were randomly assigned to receive, every 2 weeks, either arm A (FOLFIRI: irinotecan 180 mg/m(2) on day 1 with LV 100 mg/m(2) administered as a 2-hour infusion before FU 400 mg/m(2) administered as an intravenous bolus injection, and FU 600 mg/m(2) as a 22-hour infusion immediately after FU bolus injection on days 1 and 2 [LV5FU2]) or arm B (FOLFOX4: oxaliplatin 85 mg/m(2) on day 1 with LV5FU2 regimen). RESULTS: One hundred sixty-four and 172 patients were assessable in arm A and B, respectively. Overall response rates (ORR) were 31% in arm A (95% CI, 24.6% to 38.3%) and 34% in arm B (95% CI, 27.2% to 41.5%; P = .60). In both arms A and B, median time to progression (TTP; 7 v 7 months, respectively), duration of response (9 v 10 months, respectively), and overall survival (OS; 14 v 15 months, respectively) were similar, without any statistically significant difference. Toxicity was mild in both groups: alopecia and gastrointestinal disturbances were the most common toxicities in arm A; thrombocytopenia and neurosensorial were the most common toxicities in arm B. Grade 3 to 4 toxicities were uncommon in both arms, and no statistical significant difference was observed. CONCLUSION: There is no difference in ORR, TTP, and OS for patients treated with the FOLFIRI or FOLFOX4 regimen. Both therapies seemed effective as first-line treatment in these patients. The difference between these two combination therapies is mainly in the toxicity profile.

RESUMO

Malignant pleural mesothelioma (MPM) is the most frequent pleural neoplasm, with asbestos exposure as one of the recognized carcinogen agents, causative in 80% of cases. The prognosis is poor; median survival of untreated cases is 6-9 months, with fewer than 5% of patients surviving 5 years. Sarcomatoid mesothelioma (SM) represents the subtype with the worst outcome and median survival ranging from 3.5 to 8 months. In the last few years, an accurate differentiation between the subtypes of MPM has become a crucial issue, due to differences in chemosensitivity and clinical outcome, and several studies have evaluated different immunohistochemical markers to better define the diagnosis. The different and worse outcome of patients with SM and, in general, nonepithelioid subtypes makes it intriguing to select these cases to better study the biomolecular profile in order to find factors linked to prognosis and/or predictive of therapeutic response. Considering recent studies on miRNA and genetic mapping, further investigation of this rare subtype might represent a field for basic and clinical-translational research providing for more tailored therapies.

RESUMO

Rearrangements of the anaplastic lymphoma kinase (ALK) gene are present in 3% to 7% of non-small-cell lung cancers (NSCLCs). Patients harboring ALK rearrangements show very favourable outcomes if treated with targeted agents, among which crizotinib is the first and best studied. Crizotinib, an oral small-molecule tyrosine kinase inhibitor of ALK, MET, and ROS1 kinases, is a very active and well tolerated drug. Nevertheless, the optimal therapy management with this new drug is still partially unknown, especially with regard to the safety of combined treatments. Recently, the integration of locoregional treatments has been proposed as a feasible multimodality strategy in selected patients with good clinical conditions and slow-growing or oligoprogressive disease. In this report, a case of advanced lung adenocarcinoma, progressed after first line chemotherapy and re-biopsied detecting ALK rearrangement, is described. During crizotinib treatment the primary lung tumor showed an excellent regression; meanwhile a major surgery for a metachronous uterine cancer was safely and successfully carried out.

RESUMO

AIMS AND BACKGROUND: Gastric and bladder metastases are rare in non-small-cell lung cancer (NSCLC) and the differential diagnosis with primary tumors requires an in-depth examination. KRAS gene mutations are the main oncogenic driver of lung adenocarcinoma in Caucasian patients, occurring in 25%-30% of cases, but their prognostic and predictive role is complex and not fully clarified. KRAS mutations in lung adenocarcinoma are considered negatively predictive for epidermal growth factor receptor tyrosine kinase inhibitors therapy as well as for adjuvant chemotherapy. In this report, the authors describe a case of lung adenocarcinoma harboring a codon 13 KRAS mutation detected in all the biopsies performed in unusual metastatic sites during an atypical disease course. CONCLUSIONS: Recently, a different prognostic significance of various KRAS mutations in lung adenocarcinoma has been suggested. Further studies on rare biomolecular alterations to identify subgroups of patients with different prognostic/predictive characteristics are needed.

RESUMO

INTRODUCTION: Cisplatin with pemetrexed (CP) and carboplatin with paclitaxel and bevacizumab (CbTB) are standard first-line treatments for patients with advanced nonsquamous (NS) non-small-cell lung cancer (NSCLC). Quality of life (QoL) is a key objective in the management of advanced NSCLC. Thus, effect on QoL could be an additional factor in the choice of treatment. PATIENTS AND METHODS: Patients with untreated stage IIIB/IV NS-NSCLC and Eastern Cooperative Oncology Group performance status of 0 or 1 were randomized to receive first-line chemotherapy with cisplatin 75 mg/m(2) and pemetrexed 500 mg/m(2), every 3 weeks, for 6 cycles followed by maintenance pemetrexed; or carboplatin area under the curve 6, paclitaxel 200 mg/m(2), and bevacizumab 15 mg/kg, every 3 weeks, for 6 cycles followed by maintenance bevacizumab. The primary end point was the difference in QoL between the 2 treatment arms after 12 weeks of maintenance, measured using the EuroQoL 5 Dimensions-Index (EQ5D-I) and EQ5D-visual analogue scale (EQ5D-VAS). RESULTS: One hundred eighteen patients were randomized to CP (n = 60) or CbTB (n = 58). Baseline characteristics were well balanced. The proportion of patients evaluable for the primary end point was lower than planned. After 12 weeks of maintenance, the difference between mean changes in EQ5D-I was 0.137, favoring CP (95% confidence interval [CI], -0.02 to 0.29, Wilcoxon P = .078), although not statistically significant; and the difference between mean changes in EQ5D-VAS was 0.97 (95% CI, -9.37 to 11.31, Wilcoxon P = .41). CONCLUSION: Although the study was underpowered because of a small number of patients evaluable for the primary end point, QoL did not differ between treatment arms. Other factors such as comorbidities and schedule should be used when deciding on first-line treatment.

RESUMO

A phase I study was conducted in order to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of the combination of vinorelbine and capecitabine in patients affected with metastatic breast cancer. Eighteen patients with histologically confirmed advanced breast cancer, who had failed =1 prior chemotherapy regimen, were enrolled. The median age was 56 years (range, 39-70 years). All but 1 had previously received a combination of anthracyclines and taxanes; performance status (Eastern Cooperative Oncology Group) was 0/1 or 2 in 13 and 5 patients, respectively. Vinorelbine was administered at a fixed dosage of 25 mg/m2 on days 1 and 8 every 3 weeks. Capecitabine was administered orally, at an escalated dose ranging from 1400 mg/m2 to 2250 mg/m2 for 14 consecutive days starting on day 1 of the cycle, divided into 2 daily doses delivered half an hour after eating at 12-hour intervals. Three patients were treated at each dose level: if 1 patient developed a DLT, an additional 3 patients were treated at the same dose level. If 2 additional patients experienced DLT, no further escalation was allowed and the previous dose level was declared MTD. Dose-limiting toxicity was reached at 2250 mg/m2 of capecitabine with 3 out of 3 patients experiencing grade 4 neutropenia plus grade 3 diarrhea and grade 3 oral mucositis in 1 patient). Thus, MTD was defined at 2000 mg/m2 capecitabine. Other observed grade 2 side effects were: 1 patient with neutropenia, 1 with hand-foot syndrome, 2 with mucositis, 1 with cutaneous rash, and 1 with thrombocytopenia. With regard to response rate, we observed 1 complete response (5.5%), 6 partial responses (33%), and 4 disease stabilizations (22%). The median time to progression was 12 weeks and the median survival 41 weeks. The MTD of capecitabine in combination with vinorelbine at 25 mg/m2 dosage on days 1 and 8 of a 3-week schedule is 2000 mg/m2/day for 14 consecutive days. Moreover, this regimen showed interesting activity with 61% overall disease control (complete plus partial response plus disease stabilization) in patients pretreated with anthracyclines and taxanes warranting further investigations in a large, multicenter phase II study.

RESUMO

Published data strongly suggest that tumor progression and malignancy are associated with increased angiogenesis. However, no data have been published concerning the relationship between microvascular density (MVD), tumor cytosol, and blood vascular endothelial growth factor (VEGF) concentrations in canine non-Hodgkin lymphoma (C-NHL), a neoplasm that shares biological and clinical characteristics with human NHL. We have evaluated MVD and tumor cytosol, serum (S), platelet-poor plasma (P-PP), plasma-activated platelet rich (P-APR) VEGF concentration in a series of 63 B-cells C-NHL by means of immunohistochemistry and enzyme-linked immuno-sorbent assay (ELISA) detection of VEGF. We found that MVD, VEGF from cytosol, and VEGF from P-APR are significantly correlated (p ranging from 0.001 to 0.003) and that these parameters paralleled with the malignancy degree of NHL. Accordingly, spontaneous C-NHL seems to be an interesting model to study the role of angiogenesis as interspecies pathway of tumor malignancy and we suggest that VEGF from P-APR might be a novel useful circulating bio-marker of tumor angiogenesis.
