Alarming Drop in Early Stage Colorectal Cancer Diagnoses After COVID-19 Outbreak: A Real-World Analysis from the Italian COVID-DELAY Study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has triggered the disruption of health care on a global scale. With Italy tangled up in the pandemic response, oncology care has been largely diverted and cancer screenings suspended. Our multicenter Italian study aimed to evaluate whether COVID-19 has impacted access to diagnosis, staging, and treatment for patients newly diagnosed with colorectal cancer (CRC), compared with pre-pandemic time. METHODS: All consecutive new CRC patients referred to 8 Italian oncology institutions between March and December 2020 were included. Access rate and temporal intervals between date of symptoms onset, radiological and cytohistological diagnosis, treatment start and first radiological evaluation were analyzed and compared with the same months of 2019. RESULTS: A reduction (29%) in newly diagnosed CRC cases was seen when compared with 2019 (360 vs 506). New CRC patients in 2020 were less likely to be diagnosed with early stage (stages I-II-III) CRC (63% vs 78%, P < .01). Gender and sidedness were similar regardless of the year. The percentage of tumors with any mutation among BRAF, NRAS, and KRAS genes were significantly different between the 2 years (61% in 2020 vs 50% in 2019, P = .04). Timing of access to cancer diagnosis, staging, and treatment for patients with CRC has not been negatively affected by the pandemic. Significantly shorter temporal intervals were observed between symptom onset and first oncological appointment (69 vs 79 days, P = .01) and between histological diagnosis and first oncological appointment (34 vs 42 days, P < .01) during 2020 compared with 2019. Fewer CRC cases were discussed in multidisciplinary meetings during 2020 (38% vs 50%, P = .01). CONCLUSIONS: Our data highlight a significant drop in CRC diagnosis after COVID-19, especially for early stage disease. The study also reveals a remarkable setback in the multidisciplinary management of patients with CRC. Despite this, Italian oncologists were able to ensure diagnostic-therapeutic pathways proper operation after March 2020.

Sequencing radium 223 and other life-prolonging agents in castration-resistant prostate cancer patients.

Background: Radium 223 (RA223) is currently administered as part of a therapeutic sequence with the other life-prolonging agents (LPAs) for metastatic castration-resistant prostate cancer (mCRPC). Patients & methods: We retrospectively reviewed the clinical records of patients who had received at least three LPAs including RA223. Results: Median overall survival (OS) from the start of first-line treatment was 39.8 months, with the patients who completed all six planned courses of RA223 having a longer OS than those who did not (53.2 vs 29.5 months; p < 0.0001). Conclusions: Our study confirms the activity of RA223 regardless of the treatment line in which it is administered and suggests that patient selection plays a central role in maximizing this activity.

Fracture risk and survival outcomes in metastatic castration-resistant prostate cancer patients sequentially treated with abiraterone acetate and RADIUM-223.

PURPOSE: To evaluate the fracture risk and survival outcomes in patients with metastatic castration-resistant prostate cancer (mCRPC) who received sequentially abiraterone acetate (AA) and radium 223 [223Ra]RaCl2 in the daily clinical practice. MATERIALS: We retrospectively reviewed the records of mCRPC patients who received [223Ra]RaCl2 immediately after progressing during an AA treatment line in everyday clinical practice. RESULTS: We reviewed data of a consecutive series of 94 mCRPC patients. Most of the patients (85.1%) received [223Ra]RaCl2 as second- or third-line treatment. [223Ra]RaCl2 treatment was well-tolerated; there were only four cases of grade 3 anaemia, two cases of grade 3 leukopenia and one case of grade 3 neutropenia. The overall fracture rate is 2.1%; one fracture was recorded during the course of [223Ra]RaCl2 treatment, and one was recorded 1 month after its end. The fractures both occurred at metastatic sites. Median OS from [223Ra]RaCl2 start was more than 14 months regardless of the treatment line when [223Ra]RaCl2 was administered. CONCLUSION: The findings of this study show that the treatment with [223Ra]RaCl2 immediately after AA was active and safe with a very low risk of a fracture. Thus, the present observational report makes a valuable contribution to the current debate concerning the risks and benefits of including [223Ra]RaCl2 in the therapeutic algorithm.

CK7 and consensus molecular subtypes as major prognosticators in V600EBRAF mutated metastatic colorectal cancer.

BACKGROUND: V600EBRAF mutated metastatic colorectal cancer (mCRC) is a subtype (10%) with overall poor prognosis, but the clinical experience suggests a great heterogeneity in survival. It is still unexplored the real distribution of traditional and innovative biomarkers among V600EBRAF mutated mCRC and which is their role in the improvement of clinical prediction of survival outcomes. METHODS: Data and tissue specimens from 155 V600EBRAF mutated mCRC patients treated at eight Italian Units of Oncology were collected. Specimens were analysed by means of immunohistochemistry profiling performed on tissue microarrays. Primary endpoint was overall survival (OS). RESULTS: CDX2 loss conferred worse OS (HR = 1.72, 95%CI 1.03-2.86, p = 0.036), as well as high CK7 expression (HR = 2.17, 95%CI 1.10-4.29, p = 0.026). According to Consensus Molecular Subtypes (CMS), CMS1 patients had better OS compared to CMS2-3/CMS4 (HR = 0.37, 95%CI 0.19-0.71, p = 0.003). Samples showing less TILs had worse OS (HR = 1.72, 95%CI 1.16-2.56, p = 0.007). Progression-free survival analyses led to similar results. At multivariate analysis, CK7 and CMS subgrouping retained their significant correlation with OS. CONCLUSION: The present study provides new evidence on how several well-established biomarkers perform in a homogenousV600EBRAF mutated mCRC population, with important and independent information added to standard clinical prognosticators. These data could be useful to inform further translational research, for patients' stratification in clinical trials and in routine clinical practice to better estimate patients' prognosis.

The role of patient-reported outcomes in outpatients receiving active anti-cancer treatment: impact on patients' quality of life.

INTRODUCTION: Patient-reported outcomes (PROs) are the gold standard to describe subjective symptoms. Nurses can be successfully involved in collecting symptom information, because of their direct relationship with the patient. In order to improve clinical management of outpatients receiving active anti-cancer treatment, we introduced in routine clinical practice an assessment of patient-reported symptoms and toxicities, starting from January 2018. Our hypothesis was that this could help to better control symptoms, improving patients' quality of life (QoL). METHODS: Eligible patients were receiving an active anti-cancer treatment, as outpatients. Patients included in the control group (treated in 2017) underwent "usual" visits (group A), while patients treated in 2018, before each visit received a questionnaire by a dedicated nurse, in order to provide information about symptoms and toxicities (group B). Primary objective was the comparison of QoL changes, measured by EORTC QLQ-C30. RESULTS: A total of 211 patients have been analyzed (119 group A; 92 group B). After 1 month, mean change from baseline of global QoL was - 1.68 in group A and + 2.54 in group B (p = 0.004, effect size 0.20). Group B showed significantly better mean changes for fatigue, pain, and appetite loss. Proportion of patients obtaining a clinically significant improvement in global QoL score was higher in group B (32.6%) compared to group A (19.3%, p = 0.04). Patients' satisfaction with questionnaire was high. CONCLUSION: Introduction of PROs in clinical practice, thanks to an active role of nurses, was feasible, produced high patients' satisfaction and a significant QoL improvement, compared to the traditional modality of visit.

FOLFOX activity in a rare case of metastatic colonic adenocarcinoma of the tongue: a case report.

BACKGROUND: Adenocarcinomas of the oral cavity are rare neoplasms, and only four cases of primary colonic adenocarcinoma of the tongue have ever been described in literature. Very few information about chemotherapy sensitiveness of this type of neoplasia is available, with only one regimen that showed some activity in a metastatic patient. CASE PRESENTATION: We describe the case of a patient bearing a metastatic colonic adenocarcinoma of the tongue submitted to a first-line chemotherapy with oxaliplatin, 5-fluorouracil and folinic acid (FOLFOX regimen). After chemotherapy the patient obtained the complete disappearance of the primitive neoplasia located in the body of the tongue, and a tumor size reduction > 50% of liver and lung metastases. CONCLUSIONS: This case demonstrated the activity of the combination of oxaliplatin and 5-fluorouracil in this very rare neoplasia. The FOLFOX regimen might be considered either in advanced and especially in the neoadjuvant setting, when the reduction of the primary tumor is highly needed.

Enhanced oxidative stress and platelet activation in patients with Cushing's syndrome.

OBJECTIVE: Cushing Syndrome (CS) is implicated by increased cardiovascular risk (CVR) leading to increased morbidity and mortality. Oxidative stress (OS) and platelet activation (PA) are associated with increased CVR. However, scarce data of OS in CS exist. Our objective was to determine the oxidant-antioxidant balance in CS. DESIGN: Fourteen patients with CS at diagnosis and fourteen healthy subjects (NS) were evaluated OS by measuring plasma 15-F2t -Isoprostane (15-F2t -IsoP), PA by thromboxaneB2 levels (TXB2 ), and antioxidant reserve measuring total antioxidant capacity (TAC) and serum vitamin E. RESULTS: 15-F2t -IsoP and TXB2 levels were significantly higher (P < 0·01) in CS, while vitamin E levels were higher in NS (P < 0·03). 15-F2t -IsoP levels were significantly higher (P < 0·01) in complicated vs not-complicated CS and NS and significantly higher (P < 0·03) in CS not-complicated vs NS. TXB2 levels were significantly reduced (P < 0·03) in NS vs complicated and not-complicated CS. A negative correlation between Vitamin E and UFC was observed in CS (P < 0·05 r = -0·497). TXB2 correlated with glucose, HbA1c and T-score (P < 0·05 r = 0·512, P < 0·03 r = 0·527 and P < 0·01 r = 0·783, respectively) and HDL (P < 0·01 r = -0·651). 15-F2t -IsoP correlated with triglicerides, HbA1c and diastolic pressure (P < 0·01 r = 0·650, P < 0·03 r = 0·571 and P < 0·05 r = 0·498, respectively) and HDL (P < 0·03 r = -0·594). CONCLUSIONS: This study emphasizes the major role of OS in CS. As our findings demonstrated that enhanced OS and PA take place in this rare metabolic disorder which is associated with increased CVR, it could be suggested that these biochemical alterations can further contribute in the pathogenesis of atherosclerosis, increased CVR and mortality in CS.

Cushing's syndrome is associated with sleep alterations detected by wrist actigraphy.

BACKGROUND: The association between the hypothalamic-pituitary-adrenal (HPA) axis and sleep is well described. It is also known that HPA axis disturbances have an effect on sleep. In fact, patients affected by Cushing's syndrome (CS) often complain about poor sleep quality. Our aim was to evaluate objective sleep quality and duration in patients with Cushing's syndrome in active phase, using wrist actigraphy. PATIENTS AND METHODS: In 12 patients with active CS without ongoing specific therapy (11 F, 1 M; age 40.0 ± 10.9 years; BMI 28.4 ± 6.7 kg/m(2)) and 12 healthy control subjects (HS) (11 F, 1 M; age 44.0 ± 11.0 years; BMI 23.9 ± 4.2 kg/m(2)) an actigraphic evaluation was performed on 3 consecutive days under free living conditions. Objective measurement of sleep duration and quality was estimated by an actiwatch, which is a wristwatch-like device used to detect motor activity. RESULTS: In CS patients, wrist actigraphy showed higher fragmented sleep (fragmentation index CS 16.2 ± 4.2, HS 13.0 ± 3.6; p = 0.034) and increased nocturnal motor activity (total activity score CS 8318 ± 4308, HS 4971 ± 2372; p = 0.020; mean activity score CS 8.7 ± 4.2, HS 5.4 ± 2.2; p = 0.030; mean score in active time CS 104.8 ± 39.2, HS 74.8 ± 23.1; p = 0.030). On the contrary, actual sleep time resulted similar in CS and HS. No correlation was found between sleep alterations and urinary free cortisol in patients. CONCLUSIONS: The impaired actigraphic parameters described in our study suggest that hypercortisolism is associated with sleep alterations, which could contribute to the worsening of life quality and metabolic comorbidities associated with CS. These results have to be confirmed in a larger cohort of patients, using more accurate instruments for sleep assessment.

The acute effect of fludrocortisone on basal and hCRH-stimulated hypothalamic--pituitary--adrenal (HPA) axis in humans.

Mineralocorticoid receptors (MR) in the hippocampus display an important role in the control of hypothalamic-pituitary-adrenal (HPA)-axis, mediating the "proactive"-feedback of glucocorticoids. Fludrocortisone (FC), a potent MR agonist, has been shown to decrease HPA activity through a mechanism placed at hippocampal level. In order to clarify the effects of MR agonism on HPA function in humans, we studied the effects of FC, in a dose-related manner, on both basal and CRH-stimulated HPA axis during the quiescent phase. 8 young women were studied. ACTH, cortisol and aldosterone levels were evaluated every 15', from 1600 to 2000 hours, in randomized sessions: (1) placebo p.o. + placebo i.v., (2) 0.3 mg FC p.o. + placebo, (3) 0.1 mg FC. + placebo, (4) 0.075 mg FC + placebo, (5) 0.05 mg FC + placebo, (6) placebo + hCRH (2.0 µg/kg iv-bolus), (7) 0.3 mg FC + hCRH, (8) 0.1 mg FC + hCRH, (9) 0.075 mg FC + hCRH, (10) 0.05 mg FC + hCRH. FC induced a dose-related trend toward a further decrease of the ACTH and cortisol levels, while it showed a significant and dose-dependent inhibition of the hormonal response to hCRH (p < 0.05 for the doses of 0.3, 0.1 and 0.075 mg). Conversely, 0.05 mg FC did not modify the CRH-stimulatory effect on both ACTH and cortisol secretion. Aldosterone levels were not modified by FC administration. Fludrocortisone inhibits corticotrope and adrenal response to hCRH in humans, in a dose-dependent manner. The 0.075 mg FC seems the lowest active while 0.05 mg the first neutral dose on HPA activity. These data suggest a possible hypophysial MR-mediated inhibiting effect of FC, although its pituitary glucocorticoid-mediated effect cannot be excluded. The interplay between fludrocortisone and hypophysial glucocorticoid receptors needs to be clarified in order to define better the clinical consequences of the hormonal replacement therapy of patients with primary adrenal insufficiency.

Acute administration of alprazolam, a benzodiazepine activating GABA receptors, inhibits cortisol secretion in patients with subclinical but not overt Cushing's syndrome.

The purpose of this study is to verify whether acute pre-treatment with alprazolam (ALP), a benzodiazepine that inhibits HPA secretion in normal subjects, could better characterize patients with subclinical Cushing's syndrome (SCS) than the 1-mg dexamethasone test (DST). In 22 patients with SCS, 10 with overt Cushing's syndrome (CS), 11 with non-functioning adrenal incidentalomas (NF) and 14 normal subjects (NS) we studied the effect of ALP (1 mg, p.o. at 2300 hours) on cortisol levels after 1-mg DST. Cortisol levels (mean ± SEM) after DST were lower (P = 0.012) in SCS (3.9 ± 0.3 µg/dl) than in overt CS (10.4 ± 1.9 µg/dl), while they were higher (P = 0.0005) than in NF (1.1 ± 0.1 µg/dl) and NS (1.5 ± 0.1 µg/dl). After ALP pre-treatment, cortisol levels further decreased (P = 0.004) in SCS (3.0 ± 0.3 µg/dl), but neither in CS (9.3 ± 1.3 µg/dl) nor in NF (1.3 ± 0.1 µg/dl) and in NS (1.3 ± 0.1 µg/dl). In SCS, cortisol levels after ALP + 1-mg DST persisted lower (P = 0.0005) than those in CS, but higher (P = 0.0005) than those in NF and NS. Considering individual cases, ALP pre-treatment reduced cortisol levels < 3 and < 1.8 µg/dl in 50 and 23 % of SCS patients, respectively. ALP amplifies the cortisol inhibition exerted by 1-mg DST in patients with SCS but not in those with CS. The clinical usefulness of ALP to increase the sensitivity of 1-mg DST to identify true autonomous cortisol release in patients with adrenal incidentalomas as well as to predict different clinical outcomes remains to be clarified.

The role of nanoliposomal irinotecan plus fluorouracil/leucovorin in the continuum of care of patients with metastatic pancreatic ductal adenocarcinoma.

BACKGROUND: The NAPOLI-I trial showed better outcome of nanoliposomal irinotecan (nal-IRI) plus 5-fluorouracil/leucovorin (5-FU/LV) compared to 5-FU/LV in patients with advanced pancreatic ductal adenocarcinoma cancer (advPDAC) progressed to gemcitabine-based therapy. This study aims to explore the real-world efficacy and safety of 5-FU/LV-nal-IRI. METHODS: This is a retrospective multicenter analysis including advPDAC patients receiving 5-FU/LV-nal-IRI after failure of gemcitabine-based therapy. Survival analyses were performed using Kaplan-Meier method, univariate and multivariate analyses by Cox regression. RESULTS: A total of 296 patients (median age 64.4 years, ECOG PS ≥1 in 56% of cases) were treated at 11 Italian institutions between 2016 and 2018. 34% of them underwent primary tumor resection, and 79% received gemcitabine-nabpaclitaxel as first line. 5-FU/LV-nal-IRI was administered as second-line in 73% of cases. Objective response and disease control rate were 12% and 41%, respectively. Treatment was well tolerated with dose reductions in 50% of patients but no one permanent discontinuation; the commonest grade ≥3 toxicities were neutropenia (14%) and diarrhea (12%). Median PFS and OS from 5-FU/LV-nal-IRI initiation was 3.2 and 7.1 months, respectively. CONCLUSIONS: These real-world data confirm the 5-FU/LV-nal-IRI efficacy and safety in advPDAC patients progressed to gemcitabine-based therapy, with outcomes comparable to NAPOLI-1, even in a less-selected population and with more modern therapeutic algorithm.

A systematic review and meta-analysis of trials assessing PD-1/PD-L1 immune checkpoint inhibitors activity in pre-treated advanced stage malignant mesothelioma.

INTRODUCTION: Advanced stage malignant mesothelioma (asMM) patients have poor prognosis. Several trials investigated the role of programmed cell death protein-1 (PD-1) and its ligand 1 (PD-L1) immune checkpoint inhibitors (ICIs) in pre-treated asMM. METHODS: A systematic review of the literature of clinical trials testing single-agent anti PD-1/PD-L1 ICIs in pre-treated asMM was performed. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS) data were extracted. The predictive role of PD-L1 was assessed. RESULTS: We selected 13 studies including 888 patients. ORR and DCR were 18.1% (95% confidence interval [CI] 13.9-22.8%) and 55.4% (95% CI: 48.1-62.5%), respectively. Median PFS and OS ranged from 2.1 to 5.9 and from 6.7 to 20.9 months, respectively. ORR according to PD-L1 was 27.0% (95% CI: 18.7-36.2%). CONCLUSIONS: Anti-PD-(L)1 ICIs might be considered a treatment option for chemotherapy-resistant asMM, even if reliable predictive factors are still lacking.

A review of molecularly targeted therapy in biliary tract carcinoma: what is the next step?

Patients with unresectable biliary tract carcinomas (BTCs) have a poor prognosis with a median overall survival of fewer than 12 months following systemic chemotherapy. In recent years, the identification of distinct molecular alterations with corresponding targeted therapies is modifying this therapeutic algorithm. The aim of this review is to present an overview of targeted therapy for BTCs, describing published available data and potential future challenges in ongoing trials. From clinicaltrials.gov online database all ongoing trials for BTCs (any stage) was examinated in July 2021, and data regarding study design, disease characteristics and type of treatments were registered. Oncogenic-driven therapy (targeted therapy) was investigated in 67 trials. According to research, 15 ongoing trials (22.4%) are investigating fibroblast growth factor (FGF) receptor (FGFR)-inhibitors in BTCs. Three (18.7%) are open-label randomized multicenter phase 3 trials, 8 (50%) are single-arm phase two trials, and 4 (25%) are phase one studies. Twelve (17.9%) clinical trials dealt with isocitrate dehydrogenase (IDH) 1/2 targeting therapy either in combination with cisplatin (Cis) and gemcitabine (Gem) as first-line treatment for BTCs or in monotherapy in patients with IDH1 mutant advanced malignancies, including cholangiocarcinoma (CCA). Nine (13.4%) clinical trials tested human epidermal growth factor receptor (HER) 2 targeting therapy. Four (44.4%) studies are phase I trials, two (22.2%) are phase I/II trials, and three (33.3%) phase II trials. Rare molecular alterations in BTCs, such as anaplastic lymphoma kinase (ALK), c-ros oncogene1 receptor tyrosine kinase (ROS1), and v-RAF murine sarcoma viral oncogene homologue B1 (BRAF), are also under investigation in a few trials. Forty-four clinical trials (17.2%) are investigating not oncogenic-driven multitarget therapy like multireceptor tyrosin kinase inhibitors and antiangiogenetic agents. In conclusion, this review shows that BTCs management is experiencing important innovations, especially in biomarker-based patient selection and in the new emerging therapeutic approach. Many ongoing trials could answer questions regarding the role of molecular inhibitors leading to new therapeutic frontiers for molecular subcategories of BTCs.

Adoption of multiple primary endpoints in phase III trials of systemic treatments in patients with advanced solid tumours. A systematic review.

BACKGROUND AND AIM: Trial designs using multiple primary endpoints (MPEs) are increasing in phase III cancer trials. Our objectives were to describe the incidence of MPEs in recently published phase III trials testing systemic treatments in patients with advanced cancer; the main characteristics of trials adopting MPEs; the presence of mature results for all endpoints in the primary publication; consistency between results of each endpoint and authors' conclusions. METHODS: Articles of randomised phase III trials conducted in patients with advanced cancer, published between 2017 and 2020, were retrieved from PubMed. The main outcome was the proportion of trials with MPEs. In principle, according to regulatory agencies, we considered two distinct cases: (i) MPEs correspond to 'multiple chances' for the success of experimental treatment, needing adjustment for multiplicity, and (ii) a positive result depends on the success in all MPEs ('co-primary' endpoints). RESULTS: Out of 235 eligible trials, 27 trials (12%) adopted MPE, mostly overall survival (OS) and progression-free survival (PFS). The proportion of trials with MPEs increased over time, from 6% in 2017 to 20% in 2020 (p = 0.025). MPEs were adopted in 16% of for-profit trials versus 4% of non-profit trials (p = 0.006). The proportion of trials adopting MPEs was particularly high with immunotherapy (53%, p < 0.00001). Out of 27 trials with MPEs, 10 (37%) adopted an explicit definition of 'co-primary' endpoints, but only 1/10 declared the positivity of both endpoints critical for interpretation. Most trials (23, 85%) planned correction for multiplicity. Of 21 publications with positive conclusions, only 12 had a statistically significant positive result in both primary endpoints. In four cases (15%), positive conclusions were based on PFS results alone. CONCLUSIONS: Adoption of MPEs in randomised trials in oncology is quite common. Only a minority of trials respect recommendations by regulatory agencies about the adoption of MPEs, definition of 'co-primary' endpoints and correction for multiplicity.

Sequencing Life-Prolonging Agents in Castration-Resistant Prostate Cancer Patients: Comparison of Sequences With and Without 223Ra.

Background: The retrospective studies that have so far described the outcomes of the sequential use of life-prolonging agents (LPAs) did not include metastatic castration-resistant prostate cancer (mCRPC) patients who received radium-223 (223Ra) as part of their treatment. Consequently, it is not known whether including 223Ra in the therapeutic sequence has an impact on cumulative survival. The aim of this study was to evaluate this impact by comparing the cumulative overall survival (OS) in two series of mCRPC patients sequentially treated with two or three LPAs after first-line docetaxel (DOC), including 223Ra and not. Materials and Methods: The authors retrospectively reviewed the records of mCRPC patients with bone involvement alone who received two or three LPAs (including 223Ra) after first-line DOC. The control group was a contemporary series of mCRPC patients with bone involvement alone treated with sequences of two or three LPAs other than 223Ra after first-line DOC. Results: Median cumulative OS was 40.6 months in the 223Ra group of 78 patients and 36.2 months in the non-223Ra group of 186 patients (p = 0.08). OS outcomes were significantly influenced by the number of treatment lines, and baseline Eastern Cooperative Oncology Group performance status (PS) and prostate-specific antigen levels. Conclusions: To the best of the authors' knowledge, this is the first study designed to evaluate the impact of introducing 223Ra in the treatment sequences for mCRPC patients, and the results show that its use does not negatively affect cumulative OS.

Synaptophysin expression in V600EBRAF-mutated advanced colorectal cancers identifies a new subgroup of tumours with worse prognosis.

BACKGROUND: Neuroendocrine differentiation has been extensively associated with worse prognosis and to mechanisms of therapy resistance in several epithelial cancers. A high prevalence of neuroendocrine differentiation was recently described in V600EBRAF-mutated (BRAFmt) metastatic colorectal cancers (mCRCs) but no data are available about its prognostic impact in this setting. METHODS: We assessed synaptophysin immunohistochemical expression in a multi-institutional series of 159 BRAFmt mCRCs with matched clinical and pathological information. Tumours were dichotomized as synaptophysin high and low. Overall survival (OS) and progression-free survival (PFS) were evaluated by Kaplan-Meier and log-rank tests. RESULTS: Thirty-five tumours (22.0%) showed any level of positivity for synaptophysin, and 18 (11.3%) were characterized by positivity in at least 20% of tumour cells. Four cases resulted 100% synaptophysin positive. The histotype of synaptophysin-positive tumours (i.e. ≥20%) was not otherwise specified in 11 cases (61.1%) and mucinous adenocarcinoma in 4 cases (22.2%). Four cases were DNA mismatch repair deficient (22.2%) and 7 (38.9%) were characterized by a high number of tumour-infiltrating lymphocytes. At multivariate analysis, high synaptophysin expression was a negative independent prognostic factor for both PFS (HR = 2.00, 95% confidence interval [CI] 1.21-3.33, p = 0.006) and OS (HR = 2.27, 95% CI 1.35-3.85, p = 0.001). CONCLUSIONS: Among BRAFmt mCRCs, synaptophysin-positive tumours are characterized by worse PFS and OS. Further studies should investigate the molecular mechanisms involved in the acquisition of the neuroendocrine phenotype to identify novel-targeted treatment strategies.

Impact of adoption of patient-reported outcomes in clinical practice on the accuracy of symptom reporting in medical records of cancer patients.

PURPOSE: Medical records are a relevant source for real-world evidence. We introduced patient-reported outcomes (PROs) in clinical practice, demonstrating a significant quality-of-life improvement, compared to usual visit. In this secondary analysis, we describe the agreement between patients' and physicians' reports of 5 symptoms. Our hypothesis was that adoption of PROs questionnaire could significantly improve the agreement. METHODS: Eligible patients were receiving active anti-cancer treatment. Patients in the control group underwent usual visits (group A), while patients of group B, before each visit, filled a PROs paper questionnaire, to provide information about symptoms and toxicities. No specific instructions were provided to physicians to integrate such information in medical records. Agreement between patient and physician evaluations was assessed by Cohen's κ, calculating under-reporting as proportion of toxicities reported by patients but not recorded by physicians. RESULTS: 211 patients (412 visits) have been analyzed. For all symptoms, Cohen's κ was better for group B: emesis (0.25 group A vs. 0.36 group B), diarrhea (0.16 vs. 0.57), constipation (0.07 vs. 0.28), pain (0.22 vs. 0.42), fatigue (0.03 vs. 0.08). For all symptoms, although under-reporting was relevant in both groups, it was lower for group B: emesis (75.49% vs. 60.0%, p=0.031), diarrhea (82.89% vs. 50.0%, p<0.001), constipation (92.11% vs. 69.57%, p<0.001), pain (59.57% vs. 42.31%, p=0.01), fatigue (82.11% vs. 64.10%, p<0.001). CONCLUSION: Adoption of paper PROs allowed a significant reduction in under-reporting of symptoms, but agreement remained suboptimal. Direct integration of electronic PROs could minimize the issue of under-reporting of medical records, increasing their accuracy.

Quality of life assessment and reporting in colorectal cancer: A systematic review of phase III trials published between 2012 and 2018.

BACKGROUND: In this study, our aim was to describe quality of life (QoL) prevalence and heterogeneity in QoL reporting in colorectal cancer phase III trials. METHODS: We included all phase III trials evaluating anticancer drugs in colorectal cancer patients published between 2012 and 2018 by 11 major journals. RESULTS: Out of the 67 publications identified, in 41 (61.2 %) QoL was not listed among endpoints. Out of 26 primary publications of trials including QoL among endpoints, QoL results were not reported in 10 (38.5 %). Overall, no QoL data were available in 51/67 (76.1 %) primary publications. In particular, in the metastatic setting, QoL data were not available in 12/18 (66.7 %) trials with primary endpoint overall survival, and in 20/29 (69.0 %) trials with other primary endpoints. CONCLUSIONS: QoL was absent in a high proportion of recently published phase III trials in colorectal cancer, even in trials of second or further lines, where attention to QoL should be particularly high.

Quality of life analysis in lung cancer: A systematic review of phase III trials published between 2012 and 2018.

OBJECTIVES: We previously reported that quality of life (QoL) is not included among trial endpoints and QoL results are underreported in a significant proportion of phase III oncology trials. Here we describe QoL adoption, reporting and methodology of QoL analysis in lung cancer trials. MATERIALS AND METHODS: We selected all primary publications of lung cancer phase III trials assessing anticancer drugs published between 2012 and 2018 by 11 major journals. RESULTS: 122 publications were included. In 39 (32.0%) publications, QoL was not listed among endpoints: in 10/17 (58.8%) early stage/locally advanced NSCLC, in 15/54 (27.8%) first-line of advanced NSCLC; in 10/41 (24.4%) second and further lines of advanced NSCLC, in 4/10 (40.0%) SCLC. Proportion of trials not including QoL was similar over time: 32.9% publications in 2012-2015 vs. 30.6% in 2016-2018. Out of 83 trials including QoL among endpoints, QoL results were absent in 36 primary publications (43.4%). Proportion of trials without QoL results in primary publication increased over time (30.6% 2012-2015 vs. 61.8% 2016-2018, p = 0.005). Overall, QoL data were not available in 75/122 (61.5%) primary publications, due to the absent endpoint or unpublished results. QoL data were lacking in 48/68 (70.6%) publications of trials with overall survival as primary endpoint, 27/54 (50.0%) with other primary endpoints and 28/54 (51.9%) publications with a positive result. For trials including QoL among endpoints but lacking QoL results in primary publication, probability of secondary publication was 6.3%, 30.1% and 49.8% after 1, 2 and 3 years respectively, without evidence of improvement comparing 2012-2015 vs. 2016-2018. CONCLUSION: QoL is not assessed or published in many phase III lung cancer trials, a setting where QoL value should be highly considered, due to high symptom burden and generally limited life expectancy. Timely inclusion of results in primary publications is worsening in recent years.

Second-line treatment options in hepatocellular carcinoma.

For many years, sorafenib has been the only approved systemic treatment for advanced hepatocellular carcinoma (HCC). For over a decade, randomized controlled trials exploring the efficacy of new drugs both in first- and second-line treatment have failed to prove any survival benefit. However, in the past few years, several advances have been made especially in pretreated patients; phase III trials of regorafenib, cabozantinib, and ramucirumab in patients with elevated α-fetoprotein have demonstrated efficacy in patients progressing after or intolerant to sorafenib. In addition, early phase I and II trials have shown promising results of immunotherapy alone or in combination with tyrosine-kinase inhibitors or monoclonal antibodies in the same setting of patients. In this review, we will discuss the evidence on second-line options for HCC, focusing on the latest results that are currently refining the treatment scenario.
