Prediction of Mortality With the Use of Noninvasive Ventilation for Acute Respiratory Failure

BACKGROUND

In actuality, it is difficult to obtain an early prognostic stratification for patients with acute respiratory failure treated with noninvasive ventilation (NIV). We tested whether an early evaluation through a predictive scoring system could identify subjects at risk of in-hospital mortality or NIV failure.

METHODS

This was a retrospective study, which included all the subjects with acute respiratory failure who required NIV admitted to an emergency department-high-dependence observation unit between January 2014 and December 2017. The HACOR (heart rate, acidosis [by using pH], consciousness [by using the Glasgow coma scale], oxygenation [by using [Formula: see text]/[Formula: see text]], respiratory rate) score was calculated before the NIV initiation (T0) and after 1 h (T1) and 24 h (T24) of treatment. The primary outcomes were in-hospital mortality and NIV failure, defined as the need for invasive ventilation.

RESULTS

The study population included 644 subjects, 463 with hypercapnic respiratory failure and an overall in-hospital mortality of 23%. Thirty-six percent of all the subjects had NIV as the "ceiling" treatment. At all the evaluations, nonsurvivors had a higher mean ± SD HACOR score than did the survivors (T0, 8.2 ± 4.9 vs 6.1 ± 4.0; T1, 6.6 ± 4.8 vs 3.8 ± 3.4; T24, 5.3 ± 4.5 vs 2.0 ± 2.3 [all P < .001]). These data were confirmed after the exclusion of the subjects who underwent NIV as the ceiling treatment (T0, 8.2 ± 4.9 vs 6.1 ± 4.0 [P = .002]; T1, 6.6 ± 4.8 vs 3.8 ± 3.4; T24, 5.3 ± 4.5 vs 2.0 ± 3.2 [all P < .001]). At T24, an HACOR score > 5 (Relative Risk [RR] 2.39, 95% CI 1.60-3.56) was associated with an increased mortality rate, independent of age and the Sequential Organ Failure Assessment score.

CONCLUSIONS

Among the subjects treated with NIV for acute respiratory failure, the HACOR score seemed to be a useful tool to identify those at risk of in-hospital mortality.

Activity of regorafenib in advanced pretreated soft tissue sarcoma: Results of a single-center phase II study

BACKGROUND

Regorafenib, a multitargeted tyrosine kinase inhibitor, proved to be active in patients with soft tissue sarcomas (STS).

METHODS

We conducted an open-label, non-randomized, single-center phase II study in advanced pretreated STS patients. Patients received regorafenib 160 mg daily on days 1 enrule 21 of a 28-day cycle. The primary endpoint was the progression-free survival (PFS) at 8 weeks. Toxicity was registered.

RESULTS

Between April 2015 and November 2016, 21 patients were enrolled in the trial. A total of 13 out of 21 evaluable patients (61.9%) were progression-free at 8 weeks. Median PFS was 3.8 months (95% CI: 2.1-9.4). Median overall survival was 14.8 months (95% CI: 7.7-27.8). In the intention-to-treat population, we reported a PFS of 66.7% at 3 months (95% CI: 40.4-83.4) and 16.7% at 12 months (95% CI: 4.1-36.5). As per the RECIST criteria, the response rate was 4.7% (1 partial response out of 21 evaluable patients) with a clinical benefit rate of 61.9%; no complete response was observed. Treatment was well tolerated.

CONCLUSION

Regorafenib shows signs of clinical activity in patients with advanced STS.

Retrospective analysis of an alternative immuno-score in clinical management of patients with pT2 urothelial carcinoma

e17038

Background: Within the mapping of the genome through the TCGA collaborative project, the urothelial carcinoma (UC) has recently revealed major intrinsic molecular subtypes, Basal, Luminal and Neural muscle-invasive UC. Here we propose a fast and standardized immuno-phenotypical score classification (Piescore), as a surrogate, which may discriminate Luminal, Basal or Neural UC and may correlate with histological and clinical variables in a mono-institutional cohort of patients treated with trans-urethral resection (TURB) and radical cystectomy (RC). Methods: This is a retrospective study of TURB specimens that harbored foci of HG pT2 (MIBC) UC from 116 pts who underwent RC. All the samples were assessed for immunohistochemical pattern, using relevant gene-expression-based markers for Basal type (CD44, CK5/6) and Luminal type (CK20 and pPARg). Piescore, investigated in both superficial and muscle-invasive component of the tumors, divided Basal and Luminal UC-types when at least 3 of the 4 markers were consistent with a specific phenotype, Mixed if two luminal and two basal markers were present simultaneously, and Neural when all four markers were negative. Results: Overall in muscle-invasive component, Piescore identified Basal phenotypes in 49 pts (42,2%), Luminal in 38 pts (32,7%), and Mixed in 9 pts (7,8%). No expression was identified in 20 pts (17,2%): 7 cases with morphological neuroendocrine differentiation and 13 cases with classical urothelial histology, all consistent with Neural phenotype. In 26,7% of cases (31/116 pts) we observed an immuno-phenotypical switch from superficial to deep component: 16 of 31 (51,6%) switched to Basal, 10 (32,2%) switched to Neural, and 5 cases (16,2%) to Mixed phenotype. No cases switched to Luminal. No cases have lost Basal phenotype from superficial to deep component, with the exception of one (switched to Neural). No statistically significant differences in terms of staging, DFS, and OS were observed in the different phenotypes. The presence of phenotypical switch did not affect angioinvasion, staging, DFS, and OS compared to non-switched cases. Conclusions: Piescore immunophenotyping (CD44, CK5/6, CK20 and pPARg) could be a simple surrogate able to stratify UC-TURB patients between Luminal vs Basal type. To our knowledge, preliminary results using the Piescore identify for the first time a phenotypical switch (to basal, Mixed or Neural) between superficial and deeper side of the same tumor, although this phenomenon did not show any prognostic implication.

An international cohort study investigating the impact of age on clinical outcome in patients with hepatocellular carcinoma treated with sorafenib

12049

Background: There is no consensus on the effect of sorafenib dosing on efficacy and toxicity in elderly patients with hepatocellular carcinoma (HCC). Older patients are often empirically started on low dose therapy with the aim to avoid toxicities whilst maximising clinical efficacy. We aimed to verify whether age impacts on overall survival (OS) of patients with HCC, and whether a reduced starting dose of sorafenib impacts on OS or rates of toxicity experienced by the elderly. Methods: In this international, multicentre cohort study, patients with a confirmed diagnosis of advanced-stage HCC receiving sorafenib were recruited from seven specialist centres. Demographic and clinical data including development and grade of sorafenib toxicity and sorafenib starting dose were collected prospectively. Survival time (months) was recorded prospectively. Outcomes for those < or > 75 years were determined Results: A total of 5598 patients were recruited; 792 (14.1%) were over the age of 75. The elderly were more likely to have larger tumours ( > 7cm)(39 vs 33%, p = 0.07) with Child-Pugh A liver function(67 vs 57.7%) and less portal vein thrombosis compared to those < 75years(22.1 vs 29.4)(p < 0.001). They were more likely to be commenced on lower starting dose of sorafenib i.e 400mg/200mg (38.7 vs 37.2%, P < 0.01). In terms of OS, there was no difference in the median OS of those >75 years and patients < 75 (7.3months vs 7.2months; HR 0.98 (95% CI 0.90–1.06), p = 0.63). There was no relationship between starting dose of sorafenib, 800mg vs 400mg/200mg, and OS between those < or > 75years. The elderly experienced a similar incidence of grade 2-4 sorafenib-related toxicity compared to < 75years(74.3 vs 61.7%, p = 0.051)(except for anorexia (14.0 vs 7.2%, p < 0.01) and rash (3.1 vs 6.3%, p < 0.05), irrespective of the dose prescribed. The elderly were more likely to discontinue sorafenib due to toxicity (27.0 vs 21.6%, p < 0.01). This did not vary between different starting doses of sorafenib. The mean duration of treatment was similar between those < and > 75 and, again, the starting dose of sorafenib did not affect treatment duration in the elderly. Conclusions: The median OS in the elderly is the same for that of patients under 75 years and is independent of the dose of sorafenib prescribed. Therefore, sorafenib should be offered to elderly patients and they should not be excluded from therapy

Do irinotecan (IRI) dose reductions driven by UGT1A1*28 genotyping prevent IRI-related severe neutropenia? A real-world study

e16116

Background: IRI is widely used in the treatment of gastrointestinal cancers. Consistent with current guidelines, UGT1A1 genotyping may drive IRI dose reductions, but the usefulness of this approach is still unclear. We assessed potential clinical variables that may predict grade ≥3 neutropenia and more specifically the upfront genotyping of UGT1A1 polymorphisms associated with IRI toxicity, according to predefined IRI dose reductions. Methods: We genotyped UGT1A1*28 polymorphisms in 247 patients with metastic colorectal, gastric and pancreatic cancers who received second or third-line IRI-based chemotherapy in clinical practice at a single academic center. Concomitant DPYD sequencing was undertaken in 179 patients receiving also fluoropyrimidines. We compared the incidence of severe neutropenia with full-dose IRI in UGT1A1 6/6 and 6/7 carriers, and in UGT1A1 7/7 carriers who underwent initial IRI dose reductions by at least 30%. Results: The incidence of UGT1A1 7/7, 6/7, 6/6 genotypes was 11.3%, 51.4%, and 37.2%, respectively. IRI dose reductions were significantly more frequent with UGT1A 7/7 and 6/7 genotypes (odds ratio [OR] = 9.5; 95% confidence interval [CI]: 4.3-21.7), and combination chemotherapy (OR = 3.8; 95%CI: 1.3 – 11.1). Other clinical parameters, including sex, cancer type, baseline neutrophils levels, performance status were not significantly associated with IRI dose reductions. Despite initial IRI reductions driven by the UGT1A1 panel, patients with UGT1A1 7/7 genotype had an increased, albeit non-significant, risk of grade ≥3 neutropenia, compared to patients with UGT1A1 6/6 and 6/7 genotypes who received full dose IRI (incidence: 39% versus 21%; OR = 2.4; 95%CI: 0.85 – 7.03). Conclusions: UGT1A1 testing is a determinant of IRI dose reductions, however this strategy does not reduce the burden of grade ≥3 neutropenia in UGT1A1 7/7 carriers. Further studies beyond the UGT1A1*28 genotype are needed to fully understand the increased risk of neutropenia in patients candidate to IRI-based chemotherapy.

The neural phenotype in invasive urothelial carcinoma patients: Alternative score detection and prognostic implication

e17037

Background: Recent molecular subtyping studies (NGS) identified a subset (5-15%) of muscle invasive urothelial carcinoma (MIBC) with transcriptomic patterns consistent with neuroendocrine (NE) differentiation in the absence of NE histology (NE-like), representing a potentially high risk subgroup of carcinoma which may require a different treatment strategy. We recently set an alternative immuno-phenotypical score (Piescore), to discriminate Luminal from Basal from Neural carcinoma. Aim of this study was to test the ability of Piescore in identifying NE-like cases in a mono-institutional cohort of patients treated with trans-urethral resection and radical cystectomy (RC) and to correlate them with clinical outcomes. Methods: Transurethral resection specimens harbored foci of HG pT2 (MIBC) UC from 116 pts who subsequently underwent RC have been submitted for immunohistochemical analysis, using relevant gene-expression-based markers for Basal type (CD44, CK5/6) and Luminal type (CK20 and pPARg). Piescore divided Basal and Luminal types when at least 3 of the 4 markers were consistent with a specific phenotype; Mixed if two luminal and two basal markers were present simultaneously; NE-like when all four markers were negative. Results: Overall, the Piescore identified Basal phenotypes in 49 patients (42,2%), Luminal in 38 (32,7%), and Mixed in 9 (7,8%). No expression was identified in 20 patients (17,2%): 7 cases with morphological NE differentiation and 13 cases with classical urothelial histology, all consistent with NE-like phenotype. Interestingly, in 10/13 patients the NE-like phenotype was only documented in the muscle invasive component of the tumor whereas in the non-invasive component they retained Luminal phenotype in 9 cases and Basal in one. With a median follow up of 188 months, the pathological stage of disease (pT2 versus ≥pT3 and/or N+) and the tumor vascular invasion (absent versus present) resulted prognostic (Stage: 5-years DFS rate 65% versus 30%, p = 0.038; 5-years OS rate 69% versus 32%, p = 0.017) (vascular invasion: 5-years DFS rate 47% versus 24%, p = 0.020; 5-years OS rate 54% versus 21%, p < 0.001) in all population. No statistically significant differences in terms of pathological stage of disease, vascular invasion, DFS, and OS were observed in NE-like cases compared with non-NE-like cases. Conclusions: The NE-like urothelial carcinoma identified by Piescore immunophenotyping (CD44, CK5/6, CK20 and pPARg) did not show any statistically significant association with worse prognosis.

Biological Characteristics and Long-term Outcomes in Node-negative Breast Cancer

BACKGROUND

Because the risk of relapse of node-negative breast cancer (BC) is varying, we evaluated the prognosis of patients with this disease and the factors associated with increased risk of relapse.

PATIENTS AND METHODS

The clinical charts of patients with BC with evidence of negative nodes and with a potential ≥ 5-year follow-up were retrospectively reviewed.

RESULTS

We analyzed 1276 patients. Over a median follow-up of 71.6 months (range, 1-227.2 months), we observed 159 events of relapse or death. The median RFS was 170 months. The median overall survival (OS) was 192 months. At univariate analysis, older age, negative hormonal receptors, larger tumor size and higher proliferation index (Ki67) were associated with worse recurrence-free survival (RFS) and OS (P < .05); higher grading was associated with worse RFS (P = .01). At multivariate analysis for RFS, age, Ki67 and tumor size confirmed their independent prognostic role. At multivariate analysis for OS, age and positive hormonal receptors showed an independent prognostic role. We observed no differences in prognosis between human epidermal growth factor receptor 2 (HER2) positive and triple-negative (TN) BC, but TNBC showed a worse OS compared with luminal-like BC.

CONCLUSIONS

In node-negative BC, age, hormone receptor status, tumor size and Ki67 were prognostic factors. The TNBC subtype was not associated with poorer prognosis compared with the HER2-positive subtype, but showed a worse OS compared with luminal-like BC.

A phase II study of the combination of gemcitabine and imatinib mesylate in pemetrexed-pretreated patients with malignant pleural mesothelioma

OBJECTIVES

Second-line chemotherapy is not a standard of care in patients with malignant pleural mesothelioma (MPM) that progresses after first-line treatment with cisplatin and pemetrexed. In pre-clinical models, the combination of gemcitabine (GEM) and imatinib mesylate (IM), compared with GEM alone, led to a further tumor growth inhibition and improved survival. This phase II study evaluates the antitumor activity of a combination of IM and GEM in platinum-pemetrexed-pretreated MPM patients expressing PDGFR-β and/or cKIT by immunohistochemistry (IHC).

PATIENTS AND METHODS

GEM (1000 mg/m²) was given on days 3 and 10; IM (400 mg) was taken orally on days 1-5 and 8-12 of a 21-day cycle. The primary endpoint was the 3-month progression-free survival (PFS) rate. The study follows the optimal two-stage design of Simon. A 3-month PFS target of 75 % was required. With a probability error α = 10 % and a power of 80 %, the calculated sample size was 22 patients. In particular, in the first step, six out of nine patients and globally 14/22 patients free from progressive disease at 3 months were required. Secondary endpoints included response rate, duration of response, toxicity and overall survival (OS).

RESULTS

In total, 23 patients were enrolled (ECOG PS 0-1/2: 9/13; one previous line/≥two previous lines: 10/13). Partial response was achieved in four patients (17.4 %) and stable disease in 11 (47.8 %) with a disease control rate of 65.3 %. After a median follow-up of 34.5 months, median PFS and OS were 2.8 and 5.7 months, respectively. The 3-month PFS rate was 39.1 % (9/23 patients). All-grade drug-related adverse events occurred in 17 (73.9 %) patients. Grade 3 treatment-related adverse events were observed in four (17 %) patients.

CONCLUSIONS

The combination of IM and GEM is well tolerated in platinum-pemetrexed-pretreated MPM patients expressing PDGFR-β and/or cKIT by IHC, but it does not show a significant PFS benefit.

Prognostic factors and outcome of HER2+ breast cancer with CNS metastases

Aim: Trastuzumab prolongs progression-free and overall survival in HER2+ breast cancer (BC), but these are associated with increased distant recurrences and central nervous system metastases (CNSm). We retrospectively evaluated outcome and prognostic factors in CNSm and non-CNSm patients. Methods: Records of HER2+ BC treated in 2000-2017 were reviewed. Results: 283/1171 (24%) HER2+ BC patients developed metastatic disease. 109/283 patients (39%) have CNSm associated with worse prognosis and increased risk of death (hazard ratio: 4.7; 95% CI: 3.5-6.4). Prognostic factors were: number of CNSm (single vs multiple lesions; 3-year overall survival 39 vs 18%; p = 0.003); brain radiation (30 vs 14%; p < 0.001); new HER2-targeting therapies (30.6 vs 22.5%; p = 0.025). Conclusion: Prognosis of BC patients with CNSm has improved using HER2-targeting therapies but remains poor.

The role of laparoscopic surgery in isolated adrenal metastasis: our personal experience

BACKGROUND

Over the past 25 years, mini-invasive adrenalectomy has become the treatment of choice for most adrenal diseases, and even adrenal malignancies in selected cases. The aim of this retrospective evaluation is to assess the effectiveness of laparoscopic adrenalectomy as a treatment of choice for adrenal metastases.

METHODS

From 2008 to 2018, 207 laparoscopic adrenalectomies have been performed in our Department of Surgery. Among these, in 12 cases the indication to adrenalectomy was metastatic adrenal lesion.

RESULTS

The right adrenal gland was removed in 8 cases and the left adrenal gland in 4 cases. A complete resection (R0) was achieved in all patients. The median operative time was 130.6 ± 23.3 min. The median postoperative hospitalization was 3.5±2.0 days. Only one patient showed postoperative grade II complications, according to Clavien-Dindo classification. All patients underwent follow-up at 6-12-18 months without showing disease recurrence. There was no intra and perioperative mortality. Conversion to laparotomic surgery has never been performed. Mean tumor size was 2.4 cm ±1.6 cm.

CONCLUSIONS

Laparoscopic adrenalectomy for metastasis permits to achieve similar results to the open approach in term of oncological outcomes, but gaining in terms of postoperative hospitalization, intra and post-operative complications as well a greater patient compliance.

Voice prosthesis rehabilitation after total laryngectomy: are satisfaction and quality of life maintained over time?

Total laryngectomy is the standard of care for advanced laryngeal/hypopharyngeal cancer. Effective voice rehabilitation is mandatory and tracheo-oesophageal speech (TES) has progressively gained approval. In 2011, we evaluated quality of life (QoL) and satisfaction after TES rehabilitation, demonstrating its efficacy in highly motivated subjects. The aim of the present study was to investigate whether those results are maintained over time within the same selected cohort. 15 of 24 patients were left with a minimum 12 year-follow up after voice prosthesis (VP) implantation. Short Form 36-Item Health Survey (SF-36) for QoL assessment and a study-specific structured questionnaire for evaluation of TES-related satisfaction were employed. The 9/24 patients who dropped out from the follow-up were excluded from the original count and the former results were recalculated. A control group of subjects with minor ENT diseases was used for SF-36 analysis. Many SF-36 items (RP, BP, SF, RE) significantly improved over time, approaching the results of the control group. VP duration also increased (6.3 ± 3.1 against 3.0 ± 1.8 months). TES-related satisfaction items did not change in a statistically significant way. Three patients (20.0%) would not have chosen the same kind of voice restoration: these subjects are those more distant from our institution (230 km and 462 km, respectively, against a mean distance of 15.4 ± 13.8 km for other patients). With the present work, we highlight how the striking results of TES can not only be maintained over time (i.e. TES-related satisfaction), but also substantially improve (i.e. QoL). An integrated, widespread network of centres for VP management is needed to optimise patient follow-up and allow studies on larger series.

Regorafenib in patients with refractory metastatic pancreatic cancer: a Phase II study (RESOUND)

Aim: Regorafenib may be active in different cancer types. This Phase II trial included patients with various refractory cancer types treated with regorafenib. Here, we report the results of the pancreatic adenocarcinoma cohort. Methods: The primary end point was progression-free survival (PFS) rate at 8 weeks; further investigation of regorafenib would be warranted with a PFS rate ≥50%. Results: A total of 20 patients were enrolled. The best response was stable disease in four patients (20%). The 8-week PFS rate was 25% with a median PFS of 1.7 months (95% CI: 1.5–2.0). A total of 13 patients (65%) experienced grade 3–4 treatment-related adverse events. Conclusion: The study did not meet its primary end point. Further investigation of regorafenib monotherapy in this setting is not recommended.

Another hospital admission through the emergency room? Looking for a fragility pattern in advanced cancer patients

65

Background: Cancer patients (pts) are often treated with anticancer therapy (CT) even in the last months of life and are often hospitalized through an access to the emergency room (ERa). This is frequently the time when a palliative care (PC) service starts, or when pts die. Methods: We performed a retrospective analysis of pts admitted to our Oncology Unit through an ERa. We evaluated: pts’ characteristics, histology, date of diagnosis, sites of metastases, comorbidities, previous CT and radiotherapy (RT), imaging procedures and other exams in the last 90 days (90d), previous ERa and admissions for supportive care (SC), including transfusions, parenteral/enteral nutrition, high-cost antibiotics, in the last 90d. Pts were divided into 2 fragility groups: less fragile (LF), candidate after discharge to further CT or follow-up, and more fragile (MF), pts candidate to PC or who died in the Oncology Unit. Results: From August 2017 to May 2018 441/756 pts (58.3%) were admitted through an ERa: women/men 219/222, median age 65.4 years (y), range (r) 18.9 - 89.7. 328 pts had visceral metastases, 287 pts had ≥1 comorbidity, 318 pts received ≥1 line of CT (r 1-8), 121 pts received ≥1 RT (r 1-5), 240 pts had ≥1 prior admission for SC (r 1-6), 224 pts had an ERa (r 1-6) and 141 pts had ≥1 hospitalization for SC (r 1-4) in the last 90d, 386 pts received ≥1 diagnostic exam in the last 90d (r 1-12). Pts were grouped as follows: LF/MF 236/205. Differences between the 2 groups were: pts ≥70 y 31% in LF, 40% in MF, p=0.047; visceral metastases 70.1% in LF, 85.1% in MF, p<0.001; ≥1 line of CT 64% in LF, 81% in MF, p<0.001; ≥1 RT 23% in LF, 32% in MF, p=0.036; admissions for SC 47% in LF, 62.9% in MF, p<0.001; ERa in the last 90d 39% in LF, 64% in MF, p<0.001; admissions for SC in the last 90d 24.4% in LF, 39.4% in MF, p=0.004. No other differences were observed between the 2 groups. Conclusions: We identified a MF profile: pts ≥70 y, with visceral metastases, ≥1 line of CT and ≥1 RT course for advanced disease, ≥1 prior hospitalization for SC, ≥1 ERa and ≥1 admission for SC in the last 90d. The identification of this fragility profile may help oncologists timely offer a PC program to advanced stage pts. This could prevent some ERa and hospital admissions close to the end of life.

P05.08 High-grade gliomas and immunotherapeutic early phase clinical trials: a single-center experience

BACKGROUND

Patients with high-grade gliomas (HGGs) have historically been excluded from immunotherapeutic early-phase clinical trials (ieCTs) due to unavailability of serial bioptic sampling, the frequent need of corticosteroids, concerns regarding activity of immunotherapy in central nervous system, and rapid clinical deterioration.

MATERIAL AND METHODS

We retrospectively reviewed data of all recurrent HGG patients enrolled in ieCTs at Humanitas Cancer Center Phase I Unit between 2014 and 2019. Disease control rate (DCR) according to RANO criteria, six-months progression-free and overall survival (PFS-6; OS-6), and treatment-related adverse events (TRAEs), were evaluated. A control-cohort (CC) of patients treated with standard treatments (temozolomide, fotemustine, lomustine and procarbazine, bevacizumab) matched (1:1) for sex, age, line of treatment, MGMT methylation status, and IDH mutational status, was selected for comparison. A series of clinical parameters with an established prognostic value for patients with solid tumors treated into ieCTs were correlated with survivals through an univariate analysis. These include: use of steroids, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, lactate dehydrogenase, albumin, total protein.

RESULTS

Five among the 23 ieCTs conducted at our Phase I Unit allowed inclusion of HGG patients. 25 patients were enrolled in the experimental cohort (EC): 22 (88%) glioblastoma, 3 (12%) anaplastic astrocytoma. Median age was 50 years (range 25–71); 16 patients (64%) were men, 9 (36%) women; 17 pts (68%) required steroid therapy, with a median baseline dexamethasone dose of 2 mg (range 1–6). The median number of prior systemic therapies was 1 (range 1–2). Twelve patients (48%) received monotherapies (anti PD-1, anti CSFR-1, anti TGF-ß, anti cereblon), 13 (52%) combination regimens (anti PD-L1 + anti CD38, anti PD-1 + anti CSFR-1). DCR was 40% (1 CR + 2 PR + 7 SD) and 37% (9 SD), in EC and CC, respectively. Four patients (16%) in EC had grade ≥3 TRAEs (1 neutropenia, 1 pneumonia, 2 hepatitis). With a median follow-up of 14 months PFS-6 were 35% and 16% (p=0.075), in EC and CC respectively, while OS-6 was significantly improved in the EC (82% vs 44%, p=0.004). In our small series, none of clinical factors resulted prognostic.

CONCLUSION

Survival outcomes of ourHGG patients treated into ieCTs compared very favorably with a matched CC. Inclusion of HGGs patients into ieCTs should be strongly encouraged. Identification of clinical factors to select who may benefit from ieCTs still remains crucial.

The supraclavicular artery island flap (SCAIF) in head and neck reconstruction: an Italian multi-institutional experience

The supraclavicular artery island flap (SCAIF) is a thin and pliable pedicled flap that is easy and quick to harvest. Thanks to its particular features and high reliability, it is best indicated for the elderly or most fragile patients. SCAIF is very versatile, as it can be used for reconstruction of oral cavity, oropharynx, hypopharynx, facial and cervical skin and tracheostomal defects. We began using this flap in four Italian tertiary referral centres, with several indications, both as first treatment and as salvage surgery. The aim of the study was to demonstrate the easy reproducibility of the flap among four different centres. A series of 28 patients underwent head and neck reconstructions with SCAIF with no recorded complications during flap harvesting. After the very first cases, harvesting time was approximately 45 minutes; 24 patients had successful flap integration at the recipient site, while the remaining 4 suffered from partial flap necrosis, two of whom needed revision surgery. Other minor complications were reported at the recipient site, always at the most distal and most delicate portion of the flap. Donor site was always closed primarily, with only three cases of partial suture dehiscence. We only selected the most fragile patients for SCAIF reconstruction, such as the elderly or those with one or more comorbidities; for this reason, we reported some serious systemic complications and one intraoperative death. SCAIF is an easy reproducible flap, with multiple possible indications. Its use as an alternative to free flaps in the head and neck region is nowadays under discussion. Its use should be encouraged among head and neck surgeons thanks to its various advantages.

Peripheral Blood Stem Cells versus Bone Marrow for T Cell-Replete Haploidentical Transplantation with Post-Transplant Cyclophosphamide in Hodgkin Lymphoma

Haploidentical stem cell transplantation (haplo-SCT) with post-transplant cyclophosphamide (PT-Cy) represents a potential curative strategy for patients with Hodgkin lymphoma (HL) when a matched related or unrelated donor is not available. The role of graft source, either bone marrow (BM) or peripheral blood stem cells (PBSCs), in this setting has not been fully elucidated. We performed a retrospective study on 91 patients with HL to compare the outcome after BM (n = 53) or PBSC (n = 38) transplant. Eighty-nine patients engrafted with no difference between BM and PBSCs in terms of median time for neutrophil (20 versus 20 days, P = .405) and platelet (26 versus 26.5 days, P = .994) engraftment. With a median follow-up of 40.2 months, 100-day cumulative incidences of grades II to IV acute graft-versus host disease (GVHD) and grades II to IV acute GVHD were 24% and 4%, respectively. Graft source was not associated with a different risk of acute GVHD both by univariate and multivariate analyses. Consistently, 1-year cumulative incidence of chronic GVHD was 7% with no differences between the 2 graft types (P = .761). Two-year rates of overall survival (OS), progression-free survival (PFS), nonrelapse mortality, and GVHD/relapse-free survival (GRFS) were 67%, 58%, 20%, and 52%, respectively. By univariate analysis, pretransplant disease status was the main variable affecting all outcomes. By multivariate analysis, PBSCs resulted in a protective factor for OS (hazard ratio [HR], .29; P = .006), PFS (HR, .38; P = .001), and GRFS (HR, .44; P = .020). The other independent variables affecting the final outcome were pretransplant disease status and hematopoietic cell transplant-specific comorbidity index. In conclusion, when planning a haplo-SCT with PT-Cy for patients with poor-risk HL, graft type is an important variable to take into account when selecting the best available donor.

Clinical and prognostic implications of sarcopenia in patients affected by locally advanced NSCLC

e20046

Background: Sarcopenia is a loss of skeletal muscle mass that has been studied as prognostic factor in several cancers. Retrospective studies have suggested that sarcopenia is associated with poorer survival outcomes and with an increase of major chemotherapy toxicities resulting in dose reduction and delay. This study examined the value of sarcopenia in patients with stage III non-small cell lung cancer (NSCLC). Methods: This retrospective analysis includes 68 patients affected by stage III NSCLC treated with induction chemotherapy followed by surgery or radical radiation therapy in our cancer center. Weight and height were obtained from medical records at diagnosis. Skeletal muscle index (SMI) was measured by the analysis of electronically stored computed tomography images obtained before the start of chemotherapy; sarcopenia was defined by international consensus as a SMI≤39 cm2/m2 for women and ≤55 cm2/m2 for men. Kaplan-Meier method and Log-Rank test were used to determine the impact of sarcopenia on overall survival (OS) and progression-free survival (PFS). Exact Fisher test and Chi-squared test were used to establish the association between the presence of sarcopenia and other variables. Results: A total of 68 patients (stage 3A = 39; stage 3B = 29) with performance status 0-1 and median age 67 yrs were analyzed. Forty-five patients (66%) were sarcopenic: 100% of underweight patients (BMI ≤18.5), 83% of patients with normal weight (BMI 18.5-24.9), 56% of overweight patients (BMI 25-29.9) and 30% of obese (BMI≥30). Sarcopenia was not associated with age≥70 yrs (p = 0.67), Charlson Comorbidity Index (p = 1.00), stage (p = 0.53), response rate to chemotherapy (p = 0.78) or toxicities of grade≥3 (p = 0.83). Median OS in sarcopenic patients was 18.2 months compared with 33.2 months in nonsarcopenic patients (p = 0.03); the difference in terms of PFS was not statistically significant (10.7 vs 14.9 months; p = 0.19). Conclusions: Sarcopenia is associated with shorter OS in patients with locally advanced NSCLC but it seems not related with worse response to induction chemotherapy or higher toxicities. These data should be validated in larger prospective clinical studies.

High-grade gliomas (HGGs) and immunotherapeutic early-phase clinical trials (ieCTs): A single-center experience

e13512

Background: Patients with HGGs have historically been excluded from ieCTs due to unavailability of serial bioptic sampling, frequent need of corticosteroids, concerns on activity of immunotherapy in central nervous system, and rapid clinical deterioration. Methods: We retrospectively reviewed data of all recurrent HGG patients enrolled in ieCTs at Humanitas Cancer Center Phase I Unit between 2014 and 2018. Disease control rate (DCR) according to RANO criteria, six-months progression-free and overall survival (PFS-6; OS-6), and treatment-related adverse events (TRAEs), were evaluated. A control-cohort (CC) of patients treated with standard treatments (temozolomide, fotemustine, lomustine and procarbazine, bevacizumab) matched (1:1) for age, line of treatment, MGMT methylation and IDH mutational status, was selected for comparison. Clinical parameters including use of steroids, neutrophil-to-lymphocyte ratio, lactate dehydrogenase, albumin, total protein, were correlated with survival through an univariate analysis. Results: 5 among 21 ieCTs allowed inclusion of HGG patients. 20 patients were enrolled in our experimental cohort (EC); 17 (85%) glioblastoma, 3 (15%) anaplastic astrocytoma. Median age was 53 years (range 30-71); 12 patients (60%) were men, 8 (40%) women; 13 pts (65%) required steroid therapy, with a median dexamethasone dose of 2 mg (range 1-6). The median number of prior systemic therapies was 1 (range 1-2). 11 patients (55%) received monotherapies (anti PD-1, anti CSFR-1, anti TGF-ß, anti cereblon), 9 (45%) combination regimens (anti PD-L1 + anti CD38, anti PD-1 + anti CSFR-1). DCR was 45% (1 CR + 2 PR + 6 SD) and 30% (1 RP +5 SD), in EC and CC, respectively. 4 patients (20%) in EC had grade ≥3 TRAEs (1 neutropenia, 1 pneumonia, 2 hepatitis). With a median follow-up of 22 months PFS-6 and OS-6 were 53% and 11% (p < .0001), 80% and 42% (p < 0.0001) in EC and CC, respectively. In our small series, none of clinical factors resulted prognostic. Conclusions: Survival outcomes of our HGG patients treated into ieCTs compared very favorably with a matched CC. Inclusion of HGGs patients into ieCTs should be strongly encouraged. Identification of clinical selection factors remains crucial.

Radial vs ulnar forearm flap: a preliminary study of donor site morbidity

The objective of this study was to compare donor site morbidity after reconstructive surgery with Ulnar Forearm Free Flap (UFFF) and Radial Forearm Free Flap (RFFF) with subjective methods. The UFFF and the RFFF were applied for reconstruction of soft tissue defects of the head and neck region in 30 patients (20 M and 10 F; age range 28-75 years) affected by head and neck squamous cell carcinoma. The Disability of Arm, Shoulder and Hand (DASH) questionnaire was used to assess morbidity of the donor site. Analysis of the patients’ DASH scores showed an overall median DASH total score of 9.17. No significant differences were observed for median values of the RFFF and UFFF groups (7.14 vs 10 respectively) or for the values in males and females (5 vs 13.3 respectively). The UFFF can be considered a valid alternative to the RFFF for reconstruction of soft tissue defects of the head and neck area; it is safe, easy to harvest and is not associated with major morbidities of the donor site as demonstrated by the DASH questionnaire.

Liver injury by immune checkpoint inhibitors in patients with hepatocellular carcinoma

341

Background: In patients with hepatocellular carcinoma (HCC) and baseline liver dysfunction, hepatic immune-related adverse events (HIRAEs) during immunotherapy have not been adequately characterized and their impact on subsequent treatment outcomes is not known. Methods: 40 patients with advanced/unresectable HCC and Child Pugh score A have been enrolled in first and second-line clinical trials of anti-programmed cell death protein 1 (PD-1) monoclonal antibodies (mAbs). HCC etiologies were: hepatitis C (32.5%), hepatitis B (7.5%), alcohol abuse (27.5%), other (32.5%). 7 received anti-PD-1 mAbs alone and 33 received combined regimens that included anti-PD-1 mAbs plus either anti-cytotoxic T lymphocyte antigen 4 (30.4%) or tyrosine kinase inhibitors (TKIs) (54.5%), or both (15.1%). We reviewed their liver function tests and HIRAEs onset was related to time to treatment failure (TTF). Results: Overall, 12 patients (30%) developed grade ≥ 3 hepatitis according to Common Toxicity Criteria for Adverse Events v. 4.03, resulting in 4 cases of grade 2 drug-induced liver injury per DILI Working Group criteria. Time between therapy initiation and hepatitis onset was 1.4 months (0.4-2.8) and median peak aminotransferase (AT) level was 258 IU/L (85-869). Out of 6 permanent treatment discontinuations due to adverse events (AEs), 4 were linked to hepatitis. Higher AT median levels at baseline were significantly linked to grade ≥ 3 hepatitis compared with lower grades (95 IU/L vs. 36 IU/L, respectively; p = 0.008). Etiology, age, treatment did not predict HIRAEs onset. TTF in patients in patients with grade ≥ 3 hepatitis was shorter than in the whole cohort (1.4 vs. 3.8 months, p = 0.041), while overall survival did not differ (p = 0.125). Conclusions: We observed a 30% incidence of clinically significant HIRAEs. HIRAEs represent the most frequent AEs leading to treatment discontinuation in patients with HCC undergoing treatments with immune checkpoint inhibitors. Baseline AT levels may identify patients at increased risk of grade ≥ 3 hepatitis.

Prognostic factors and disease course in patients enrolled onto clinical trials of second-line therapy for hepatocellular carcinoma

406

Background: Prognostic factors of survival and disease course in patients with hepatocellular carcinoma (HCC) and preserved liver reserves, enrolled onto clinical trials of second-line treatments after sorafenib, are unclear. Methods: This single-center database analysis included all patients with Child-Pugh A score and ECOG performance status (PS) 0 - 1 participating between 2012 and 2017 in clinical trials of second-line systemic treatments for advanced HCC. Patients received first-line sorafenib and experienced either disease progression (PD) to sorafenib or were sorafenib-intolerant. Their clinicopathologic characteristics were correlated with overall survival (OS, calculated from the first day of second-line treatment to death or last visit available), and post-treatment survival (PTS, calculated from the date of end-of-treatment to death or last follow-up). Results: Ninety-nine patients (21 sorafenib-intolerant, 78 progressors) were enrolled onto trials of checkpoint inhibitors (CPI, 23 patients), tyrosine kinase inhibitors (TKI, 44 patients) versus best supportive care (BSC, 24 patients), open-label TKI (8 patients). Overall, median OS was 9.4 months (9.6, 9.8, and 8.0 months for CPI, TKI and BSC, respectively; p = 0.493). Median time-to-treatment failure was 3.5, 4.4, 3.7 months for CPI, TKI and BSC, respectively (p = 0.561). In multivariable analyses, worse OS was linked to high neutrophil/lymphocyte ratio (Hazard Ratio, HR = 1.13; p = 0.005) and macrovascular invasion [(MVI), HR = 2.59; p < 0.001]. Second-line treatment discontinuation due to liver failure independently conferred worse PTS than adverse events (HR = 2.32; p = 0.111) or PD (HR = 3.44; p = 0.002), as did ECOG PS > 1 at EOT (HR = 3.05; p = 0.002). Death rate within 30 days of end-of-treatment was 4.2% on placebo versus 10.5% on IO versus 22.9% on TKI. Conclusions: In this homogeneous cohort of compensated HCC patients pre-treated with sorafenib, MVI and NLR at start of second-line clinical trial are prognostic factors of OS. Besides ECOG PS and liver failure, further predictors of subsequent PTS to inform treatment options beyond second-line were not identified.

Electroclinical findings and long-term outcomes in epileptic patients with inv dup (15)

OBJECTIVE

To define the electroclinical phenotype and long-term outcomes in a cohort of patients with inv dup (15) syndrome.

MATERIAL AND METHODS

The electroclinical data of 45 patients (25 males) affected by inv dup (15) and seizures were retrospectively analysed, and long-term follow-up of epilepsy was evaluated.

RESULTS

Epilepsy onset was marked by generalized seizures in 53% of patients, epileptic spasms in 51%, focal seizures in 26%, atypical absences in 11% and epileptic falls in 9%. The epileptic syndromes defined were: generalized epilepsy (26.7%), focal epilepsy (22.3%), epileptic encephalopathy with epileptic spasms as the only seizure type (17.7%) and Lennox-Gastaut syndrome (33.3%). Drug-resistant epilepsy was detected in 55.5% of patients. There was a significant higher prevalence of seizure-free patients in those with seizure onset after the age of 5 years and with focal epilepsy, with respect to those with earlier epilepsy onset because most of these later developed an epileptic encephalopathy (69.2% vs 34.4%; P = .03), usually Lennox-Gastaut Syndrome in type. In fact, among patients with early-onset epilepsy, those presenting with epileptic spasms as the only seizure type associated with classical hypsarrhythmia achieved seizure freedom (P < .001) compared to patients with spasms and other seizure types associated with modified hypsarrhythmia.

CONCLUSIONS

Epilepsy in inv dup (15) leads to a more severe burden of disease. Frequently, these patients show drug resistance, in particular when epilepsy onset is before the age of five and features epileptic encephalopathy.

Promoting Participation in a Population Screening Program for Breast and Cervical Cancer: A Randomized Trial of Different Invitation Strategies

Aims and background

Attendance level has been identified as a major determinant of cost-effectiveness of organized screening programs. We tested the effectiveness of 4 different invitation systems in the context of an organized population screening program for cervical and breast cancer.

Methods

Women eligible for invitation - 8385 for cervical and 8069 for breast cancer screening - listed in the rosters of 43 and 105 general practitioners (GP), respectively, who had accepted to collaborate in the program, were randomized to 4 invitation groups: Group A - letter signed by the GP, with a prefixed appointment; Group B - open-ended invitation, signed by the GP, prompting women to contact the screening center to arrange an appointment; Group C - letter (same as for group A), signed by the program coordinator, with a prefixed appointment; Group D - extended letter (highlighting the benefits of early cancer detection) signed by the GP, with a prefixed appointment. Assignment to the interventions was based on a randomized block design (block=GP).

Results

Assuming Group A as the reference, the overall compliance with cervical cancer screening was reduced by 39% in Group B (RR=0.61; 95% CI, 0.56-0.68) and by 14% in Group C (RR=0.86; 95% CI, 0.78-0.93); no difference was observed for Group D (RR=1.03; 95% CI, 0.95-1.1). The response pattern was similar for breast screening (Group B: RR=0.71; 95% CI, 0.65-0.76; Group C: RR=0.87; 95% CI, 0.81-0.94; Group D: RR=1.01; 95% CI, 0.94-1.08).

Conclusions

Personal invitation letters signed by the woman's GP, with preallocated appointments, induce a significant increase in compliance with screening. Efficiency can be ensured through the adoption of overbooking, provided that attendance levels are regularly monitored.

Breast Cancer Screening: Characteristics and Results of the Italian Programmes in the Italian Group for Planning and Evaluating Breast Cancer Screening Programmes (GISMa)

In 1990, GISMa (Italian Group for planning and evaluating Mammographic Screening - Gruppo Italiano per la pianificazione e la valutazione dei programmi di Screening Mammografico), a working group of operators (radiographers, radiologists, epidemiologists, clinicians, surgeons) involved in screening programmes ongoing in Italy, was created within the Italian School of Senology. The aim of this study is to illustrate data, presented at the GISMa meeting held in April 1994, concerning the characteristics of each programme and some early indicators of effectiveness. To assess these parameters (concerning compliance level, recall rate, benign/malignant biopsy ratio, detection rate, stage distribution, nodal involvement and number of cancers with a diameter under 1 cm, rate of cancer, etc.), ‘acceptable’ and ‘desirable’ standards obtained from Italian and North-European cancer screening experiences have been adopted. Most programmes have shown an acceptable standard for most of the indicators, and many of them have attained desirable levels. In most screening programmes the occurrence of interval cancers has not yet been measured, but all centres have (or are working to set up) a systematic active procedure to collect the data. The results indicate that common guidelines can be adopted, even when working in very heterogeneous contexts, and that it is possible to achieve a very high effectiveness and efficacy level. As regards quality control and cost/benefit issues, the goal of extending centralised, population-based screening programmes to other Italian regions becomes a priority.

General Practitioners and Mammographic Screening Uptake: Influence of Different Modalities of General Practitioner Participation

Aims and background

To compare the impact of different modalities of general practitioner (GP) involvement, including the introduction of target payments, on the attendance rate of organized population-based screening programs for breast cancer in Italy.

Study design

The study was conducted between 1994 and 1996 in four Italian cities where mammographic screening programs are active: Caltanissetta (CL), Firenze (Fl), Modena (MO) and Torino (TO). The impact on attendance rate of different invitation strategies based on active GP involvement was tested in each center. The additional effect of economic incentives was also assessed. The incentives were proportional to the level of compliance attained by each GP and weighted by the size of his eligible patients’ list.

Results

In the Firenze project, an invitation signed by the GP and the project co-ordinator attained a statistically significant higher participation (difference: 4.2%, χ2 = 7.42, P = 0.006). In Caltanissetta and Torino there was a significant increase of about 7% in the response rate to the postal reminder in the groups contacted by the GPs. No difference was observed in the Modena project between the two groups.

Conclusions

The main contributions of GP involvement can be: “cleaning up'’ the invitation lists, especially when computerized archives with the mammographic history of the target population are not available; increasing the women's participation by signing the invitation letter, by counseling and active participation in the invitation phase; co-operating in the reminder phase by recalling women non responders at first invitation. The offer of target payment had a certain impact on the screening uptake, but not easily distinguishable from GP signature of the invitation letter; further studies of appropriate design should be planned. Organizational factors, such as availability of a list of non-responders, might be crucial in order to enhance the effect of the GPs’ action.

The entity of thermal-crush-avulsion hand injury (hot-press roller burns) treated with fast acting debriding enzymes (nexobrid): literature review and report of first case

Hand burns are present in >60% of all burn cases and in fire mass casualty incidents even up to 100%. Most trauma and especially burns may be detrimental to the complex and delicate structures of the hand by direct injury, indirect BICS (Burn Induced Compartment Syndrome and interstitial high pressure) or by delayed or faulty treatment. BICS represents a special threat as the increasing swelling and oedema of the small diameter hand and forearm will exert pressure on the capillary/venous system, eventually ending in irreversible damage to the skin, nerves, muscle and vascular bed. Immediate release of constricting skin by incisional escharotomy and sometimes fasciotomy may arrest this vicious cycle: escharotomy is simple for experienced hand or burn surgeons, but they are not always present at the primary treatment site. The diagnosis of BICS is not simple either, as the direct measurement of interstitial/compartment pressure is rarely done. Burns caused by hot rollers such as industrial linen ironing machines are especially traumatic as besides the "simple" thermal burn, the hot rollers exert immense crushing pressure to the hand caught between the rollers. Over the last few years, several publications have described the role of a newly approved Bromelain derived enzymatic debriding agent (NexoBrid) for burns in general and hand burns in particular, and its ability to resolve or prevent BICS. We present a rare severe thermal/crush hand injury case where we were able to successfully treat the patient with NexoBrid enzymatic debridement-escharotomy.

Effect of Comorbidities in Stage II/III Colorectal Cancer Patients Treated With Surgery and Neoadjuvant/Adjuvant Chemotherapy: A Single-Center, Observational Study

BACKGROUND

Comorbidity has a detrimental effect on cancer survival, however, it is difficult to disentangle its direct effect from its influence on treatment choice. In this study we assessed the effect of comorbidity on survival in patients who received standard treatment for resected stage II and III colorectal cancer (CRC).

PATIENTS AND METHODS

In total, 230 CRC patients, 68 rectal (29.6%) and 162 colon cancer (70.4%) treated with surgical resection and neoadjuvant/adjuvant chemotherapy from December 2002 to December 2009 at Humanitas Cancer Center were retrospectively reviewed. The key independent variable was the Charlson Comorbidity Index (CCI) score, measured as a continuous variable. The differences between groups for categorical data were tested using the χ² test. Actuarial survival curves were generated using the Kaplan-Meier method.

RESULTS

Median follow-up was 113 (range, 8.2-145.0) months. Median age was 63 (range, 37-78) years. In univariate analysis CCI score was significantly associated with poorer disease-free survival (hazard ratio [HR], 1.65; 95% confidence interval [CI], 1.52-1.80; P < .001), and overall survival (OS; HR, 1.55; 95% CI, 1.41-1.71; P < .001). Factors associated with poorer outcome also included (stage III vs. stage II, P < .029) and age (age >70 vs. ≤70 years, P < .001). After adjusting for these factors, a significant negative prognostic role of CCI score was still observed (adjusted HR for OS, 1.59; 95% CI, 1.43-1.76; P < .001).

CONCLUSION

Among CRC patients who underwent surgical resection and chemotherapy, a higher CCI score was associated with poorer outcome and might predict long-term survival.

Quality of life and current needs of cancer survivors enrolled in Humanitas Research Hospital's survivorship care model

170

Background: While there are different studies investigating the quality of life (QoL) of cancer patients (pts) during active treatment, few studies report QoL of cancer survivors (CS) after at least 5 years (yrs) from achieving complete remission. We have investigated QoL and concerns about physical\psychological symptom of CS enrolled in our survivorship program from April 2015 to December 2016. Methods: We included pts > 18 yrs affected by hematologic or solid tumors after at least 5 yrs from achieving complete remission. A cross-sectional survey was carried out using validated scales: Cancer Survivors Survey of Needs subscale and a single-item measure of global QoL perception. Results: We analyzed data from 178 CS. The median age was 62 yrs (52 yrs at diagnosis), 70% were females. The most frequent histological types were breast (50%), colorectal (11%) and hematologic tumors (16%). Most pts received both chemotherapy and radiation therapy. With a median observation time of 139 months, the 10-yrs cumulative incidence of second neoplasm and cardiac adverse event was 8% and 7% respectively. 133 pts (65%) reported a good QoL (score > 3). The most frequent symptoms reported were weight changes (77%), memory\concentration deficit (65%), dental\mouth problems (61%). The most common physical\psychological symptoms were fear of relapse (83%), genetic counseling (68%), living with uncertainty (66%). A positive statistically significant association (p < 0.05) was observed between previous hormonal therapy and the following concerns (score ≥2): sleep disturbance (42% vs 35%); weight gain (31% vs 24%), osteoporosis (35% vs 18%), living with uncertainty (44% vs 38%). Female reported more fear of relapse (p 0.023) and sense of uncertainty (p 0.006) than males. 92% of pts have fully or partially adhered to the survivorship care plan. Conclusions: Most CS have a good QoL perception but we observed a high percentage of pts with a low score indicating different needs to be addressed. Pts treated with hormonal therapy are at higher risk of having both physical and psychological concerns. So far, the compliance of pts with the program was high.

Robotic surgery, video-assisted thoracic surgery, and open surgery for early stage lung cancer: comparison of costs and outcomes at a single institute

Background

Robotic surgery is increasingly used to resect lung cancer. However costs are high. We compared costs and outcomes for robotic surgery, video-assisted thoracic surgery (VATS), and open surgery, to treat non-small cell lung cancer (NSCLC).

Methods

We retrospectively assessed 103 consecutive patients given lobectomy or segmentectomy for clinical stage I or II NSCLC. Three surgeons could choose VATS or open, the fourth could choose between all three techniques. Between-group differences were assessed by Fisher's exact, two-way analysis of variance (ANOVA), and Wilcoxon-Mann-Whitney test. P values <0.05 were considered significant.

Results

Twenty-three patients were treated by robot, 41 by VATS, and 39 by open surgery. Age, physical status, pulmonary function, comorbidities, stage, and perioperative complications did not differ between the groups. Pathological tumor size was greater in the open than VATS and robotic groups (P=0.025). Duration of surgery was 150, 191 and 116 minutes, by robotic, VATS and open approaches, respectively (P<0.001). Significantly more lymph node stations were removed (P<0.001), and median length of stay was shorter (4, 5 and 6 days, respectively; P<0.001) in the robotic than VATS and open groups. Estimated costs were 82%, 68% and 69%, respectively, of the regional health service reimbursement for robotic, VATS and open approaches.

Discussion

Robotic surgery for early lung cancer was associated with shorter stay and more extensive lymph node dissection than VATS and open surgery. Duration of surgery was shorter for robotic than VATS. Although the cost of robotic thoracic surgery is high, the hospital makes a profit.

Detection of somatostatin receptor subtypes 2 and 5 by somatostatin receptor scintigraphy and immunohistochemistry: Clinical implications in the diagnostic and therapeutic management of gastroenteropancreatic neuroendocrine tumors

Aims and background

Somatostatin receptor scintigraphy (SRS) is the standard method for the detection of somatostatin receptors (SSTRs). It is commonly used in gastroenteropancreatic neuroendocrine tumor (GEP-NET) staging, and represents the criterion of choice for treatment with somatostatin (SST) analogs. Immunohistochemistry (IHC) was reported as a reliable method for the detection of SSTRs with theoretically superior sensitivity over SRS.

Methods and study design

We retrospectively analyzed the sensitivity and specificity of IHC in the detection of SSTRs in a cohort of consecutive patients with GEP-NETs attending our Institute from 1997 to 2007. IHC analysis was restricted to SSTR2 and SSTR5, and the results were interpreted according to two different scoring systems. SRS was used as the gold standard.

Results

Forty-four patients were enrolled; 24 (55%) had foregut carcinoids, 9 (20%) midgut carcinoids, 2 (5%) hindgut carcinoids, and 9 (20%) had GEP-NETs of unknown primary sites. A high concordance rate between IHC and SRS was shown, irrespective of the IHC scoring system applied (73% and 70%). The sensitivity of IHC was 89.3% and 78.6% and the specificity 43.8% and 50%, depending on the scoring system used.

Conclusions

Although SSTR2 was shown to be expressed by IHC in up to 50% of tumors not visualized by SRS, SRS still remains the method of choice in the diagnostic and therapeutic management of GEP-NETs. More pathological and clinical data are needed to properly understand the clinical relevance of immunohistochemical detection of SSTR expression in the absence of tumor uptake at SRS.

Increased Il-8 Levels in the Cerebrospinal Fluid of Patients with Amyotrophic Lateral Sclerosis

Inflammation has been implicated in the pathogenesis of many neurodegenerative diseases. The chemokine IL-8 is thought to have a pathophysiological role in neurodegenerative diseases. IL-8 has recently been shown to induce death of primary cultured motor neurons in vitro. We determined IL-8 levels in the cerebrospinal fluid (CSF) from 38 patients with sporadic amyotrophic lateral sclerosis (ALS) compared to patients with other non-inflammatory neurological diseases (cerebrovascular disease, degenerative dementia, Parkinson's disease, compressive radiculo-myelopathy). Multiple sclerosis (MS) patients were used as positive controls. The levels of IL-8 in the CSF of ALS patients were significantly higher than those of patients with other, non-inflammatory neurological conditions and similar to those of MS patients. The only variable influencing IL-8 in ALS patients was sex, with higher levels in men than in women. The presence of the inflammatory cytokine IL-8 in the CSF of patients with ALS at the time of diagnosis strengthens the hypothesis of a role for this chemokine in neurodegenerative disorders.

Phase II Study of Everolimus in Patients With Thymoma and Thymic Carcinoma Previously Treated With Cisplatin-Based Chemotherapy

Purpose No effective salvage treatments are available for patients with advanced/recurrent thymoma (T) or thymic carcinoma (TC) who have progressed after platinum-based chemotherapy. This study evaluated the activity of everolimus in patients with advanced/recurrent T or TC previously treated with cisplatin-containing chemotherapy. Patients and Methods This was a single-arm, single-stage, open-label, multicenter, phase II trial. Patients received oral everolimus 10 mg/d until disease progression, unacceptable toxicity, or patient refusal. A Fleming phase II trial was designed. The null hypothesis of a true disease control rate (DCR) of 40% was tested against a one-sided alternative of a true DCR of 60% (α = β = 0.10): If disease control were achieved in ≥ 21 of the first 41 evaluable patients, everolimus could be recommended for further evaluation. Progression-free survival, overall survival, and safety were also evaluated. Results From 2011 to 2013, 51 patients were enrolled (T, n = 32; TC, n = 19). Complete remission was observed in one patient with TC, partial response in five patients (T, n = 3; TC, n = 2), and stable disease in 38 patients (T, n = 27; TC, n= 11), with a DCR of 88% (T,: 93.8%; TC, 77.8%). With a median follow up of 25.7 months, median progression-free survival was 10.1 months (T,: 16.6 months; TC, 5.6 months), and median overall survival was 25.7 months (T, not reached; TC, 14.7 months). Fourteen patients had a serious drug-related adverse event; of these patients, nine permanently discontinued treatment. Three patients died of pneumonitis while in the study. Immunohistochemical positivity for p4E-BP1 or insulin-like growth factor-1 receptor was statistically significantly related to a shorter survival. Conclusion Everolimus may induce durable disease control in a high percentage of patients with T or TC, albeit with a potential high risk of fatal pneumonitis.

Can non-invasive ventilation modify central venous pressure? Comparison between invasive measurement and ultrasonographic evaluation

Central venous pressure (CVP) is primarily measured to assess intravascular volume status and heart preload. In clinical practice, the measuring device most commonly used in emergency departments and intensive care units, is an electronic transducer that interconnects a central venous catheter (CVC) with a monitoring system. Non-invasive ventilation (NIV) consists in a breathing support that supplies a positive pressure in airways through a mask or a cask though not using an endotracheal prosthesis. In emergency settings, non-invasive ultrasonography evaluation of CVP, and hence of intravascular volume status entail the measurement by a subxiphoid approach of inferior vena cava diameter and its variations in relation to respiratory activity. In the literature, there are many studies analyzing the ability to estimate CVP through ultrasonography, rating inspiratory and expiratory vena cava diameters and their ratio, defined as inferior vena cava collapsibility index (IVC-CI). At the same time, the effects of invasive mechanical ventilation on blood volume and the correlation during ventilation between hemodynamic invasive measurement of CVP and inferior vena cava diameters have already been demonstrated. Nevertheless, there are no available data regarding the hemodynamic effects of NIV and the potential correlations during this kind of ventilation between invasive and non-invasive CVP measurements. Therefore, this study aims to understand whether there exists or not an interrelationship between the values of CVP assessed invasively through a CVC and non-invasively through the IVC-CI in patients with severe respiratory distress, and above all to evaluate if these means of assessment can be influenced using NIV.

Treatment Stage Migration Maximizes Survival Outcomes in Patients with Hepatocellular Carcinoma Treated with Sorafenib: An Observational Study

BACKGROUND

Level I evidence supports the use of sorafenib in patients with Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma, where heterogeneity in efficacy exists due to varying clinicopathologic features of the disease.

AIM

We evaluated whether prior treatment with curative or locoregional therapies influences sorafenib-specific survival.

METHODS

From a prospective data set of 785 consecutive patients from international specialist centres, 264 patients (34%) were treatment naïve (TN) and 521 (66%) were pre-treated (PT), most frequently with transarterial chemoembolization (n = 413; 79%). The primary endpoint was overall survival (OS) from sorafenib initiation with prognostic factors tested on uni- and multivariate analyses.

RESULTS

Median OS for the entire cohort was 9 months; the median sorafenib duration was 2.8 months, with discontinuation being secondary to progression (n = 454; 58%) or toxicity (n = 149; 19%). PT patients had significantly longer OS than TN patients (10.5 vs. 6.6 months; p < 0.001). Compared to TN patients, PT patients had a better Child-Pugh (CP) class (CP A: 57 vs. 47%; p < 0.001) and a lower BCLC stage (BCLC A-B, 40 vs. 30%; p = 0.007). PT status preserved an independent prognostic role (p = 0.002) following adjustment for BCLC stage, α-fetoprotein, CP class, aetiology, and post-sorafenib treatment status. PT patients were more likely to receive further anticancer treatment after sorafenib (31 vs. 9%; p < 0.001).

CONCLUSION

Patients receiving sorafenib after having failed curative or locoregional therapies survive longer and are more likely to receive further treatment after sorafenib. This suggests an incremental benefit to OS from sequential exposure to multiple lines of therapy, justifying treatment stage migration in eligible patients.

Lenalidomide and dexamethasone in patients with POEMS syndrome: results of a prospective, open-label trial

Given its anti-angiogenic activity, lenalidomide may have a role in the treatment of POEMS (Peripheral neuropathy, Organomegaly, Endocrinopathy, Monoclonal plasma cell disorder and Skin changes) syndrome. This prospective, open-label, pilot study evaluated the combination of lenalidomide + dexamethasone (RD) in 18 POEMS syndrome patients (13 pre-treated, 5 newly-diagnosed but ineligible for high-dose therapy). Treatment consisted of six cycles of lenalidomide (25 mg/day for 21 days followed by 7 days rest) plus dexamethasone (40 mg/once a week). Patients responding after six cycles continued treatment until progression or unbearable toxicity. The primary endpoint was the proportion of patients with either neurological or clinical improvement. The RD combination was considered as deserving further evaluation if 9 of the first 15 patients responded. Ten responses were observed among the first 15 enrolled patients, meeting the primary endpoint. Fifteen of 18 patients (83%) completed six RD cycles: 13 (72%) patients responded and nine had both clinical and neurological improvement. Among the 15 patients who completed the six RD cycles, four were still on treatment after a 25-month follow-up. At 39 months of follow-up, all patients were alive with a 3-year progression-free survival of 59%. No patient discontinued RD for toxicity. Overall, the RD regimen showed a high incidence of prolonged symptoms improvement and was well tolerated in most POEMS patients.

Prognostic value of the neutrophil-to-lymphocyte ratio in the ARQ 197-215 second-line study for advanced hepatocellular carcinoma

The ARQ 197-215 study randomized patients to tivantinib or placebo and pre-specified efficacy analyses indicated the predictive value of MET expression as a marker of benefit from tivantinib in hepatocellular carcinoma (HCC). We aimed to explore the neutrophil-to-lymphocyte ratio (NLR) in 98 ARQ 197-215 patients with available absolute neutrophil count and absolute lymphocyte count at baseline. The cut-off value used to define high versus low NLR was 3.0. In univariate analysis, high NLR was associated with hazard ratio (HR) for overall survival (OS) of 1.58 [95% confidence interval (CI) 1.01; 2.47; P <0.046], corresponding to median OS of 5.1 months versus 7.8 months in patients with low NLR (P = 0.044). In contrast, time to progression was not significantly affected by NLR (P = 0.20). Multivariable model confirmed that both NLR >3 (P = 0.03) and presence of vascular invasion (P = 0.017) were negatively associated with OS. After adjustment for vascular invasion, NLR independently predicted survival in both the placebo and the tivantinib cohort. For OS, no interaction was detected between NLR status and treatment (P_interaction = 0.40). Baseline NLR is an independent prognostic biomarker in patients with HCC and compensated liver function who are candidate for second-line treatments.

Neuroimaging Changes in Menkes Disease, Part 2

This is the second part of a retrospective and review MR imaging study aiming to define the frequency rate, timing, imaging features, and evolution of gray matter changes in Menkes disease, a rare multisystem X-linked disorder of copper metabolism characterized by early, severe, and progressive neurologic involvement. According to our analysis, neurodegenerative changes and focal basal ganglia lesions already appear in the early phases of the disease. Subdural collections are less common than generally thought; however, their presence remains important because they might challenge the differential diagnosis with child abuse and might precipitate the clinical deterioration. Anecdotal findings in our large sample seem to provide interesting clues about the protean mechanisms of brain injury in this rare disease and further highlight the broad spectrum of MR imaging findings that might be expected while imaging a child with the suspicion of or a known diagnosis of Menkes disease.

Prognostic and predictive role of [18 F]fluorodeoxyglucose positron emission tomography (FDG-PET) in patients with unresectable malignant pleural mesothelioma (MPM) treated with up-front pemetrexed-based chemotherapy

The aim of this study was to evaluate the role of metabolic parameters analyzed at baseline and at interim FDG‐PET in predicting disease outcome in unresectable MPM patients receiving pemetrexed‐based chemotherapy. A consecutive series of MPM patients treated between February 2004 and July 2013 with first‐line pemetrexed‐based chemotherapy, and evaluated by FDG‐PET and CT scan at baseline and after two cycles of chemotherapy, was reviewed. Best CT scan response was assessed according to modified RECIST criteria. Progression‐free survival (PFS) and overall survival (OS) were correlated with FDG‐PET parameters, such as maximum standardized uptake value (SUV_max), total lesion glycolysis (TLG), and percentage changes in SUV_max (∆SUV) and TLG (∆TLG). Overall, 142 patients were enrolled; 77 (54%) received talc pleurodesis before chemotherapy. Baseline SUV_max and TLG showed a statistically significant correlation with PFS and OS (P < 0.05) in both group of patients (treated and untreated with pleurodesis). In 65 patients not receiving pleurodesis, SUV_max reduction ≥25% (∆SUV ≥ 25%) and TLG reduction ≥30% (∆TLG ≥ 30%) were significantly associated with longer PFS (P < 0.05). Patients showing both ∆SUV ≥ 25% and ∆TLG ≥ 30% responses had a significant reduction in the risk of disease progression (HR:0.31, P < 0.001) and death (HR:0.52, P = 0.044). Neither ∆SUV nor ∆TLG showed similar association with survival outcomes in patients treated with pleurodesis. Our study confirmed the prognostic role of baseline FDG‐PET in a large series of MPM patients treated with first‐line pemetrexed‐based chemotherapy. Moreover, use of ∆SUV ≥ 25% and ∆TLG ≥ 30% as cut‐off values to define early metabolic response supported the role of FDG‐PET in predicting disease outcome and treatment response in patients not receiving pleurodesis.

Oncological and complication assessment of CO2 laser-assisted endoscopic surgery for T1-T2 glottic tumours: clinical experience

Several therapeutic options are used for treatment of early stage glottic carcinoma (Tis/T1/T2): open partial laryngectomy (OPL), radiotherapy and CO2 laser-assisted endoscopic surgery. Laser surgery has gradually gained approval in the management of laryngeal cancer. We present our experience in endoscopic laser surgery for early stage glottic carcinomas. This was a retrospective analysis of 72 patients with T1-T2 glottic cancer treated with laser cordectomy between 2006 and 2012. All patients had at least a 36-month follow-up period. Percentages for disease-specific survival, disease-free survival (DFS) and laryngeal preservation rates were 98.6%, 84.7% and 97.2% respectively. Considering neoplastic features that could predict long-term oncological outcome, tumoural involvement of anterior commissure and pathological staging (pT) significantly correlate with local recurrence (p = 0.021 and p = 0.035) and with a lowered DFS (p = 0.017 and p = 0.023). Other variables such as clinical staging, type of cordectomy, involvement of other structures and surgical margin status showed no significant impact on oncological endpoints. CO2 laser surgery is a reliable technique for T1-T2 glottic cancer considering oncological outcomes. The recurrence rate seems to be affected by involvement of anterior commissure and pT stage.

Open partial horizontal laryngectomies: is it time to adopt a modular form of consent for the intervention?

Nowadays, open partial horizontal laryngectomies (OPHLs) are well-established procedures for treatment of laryngeal cancer. Their uniqueness is the possibility to modulate the intervention intraoperatively, according to eventual tumour extension. An OPHL procedure is not easy to understand: there are several types of procedures and the possibility to modulate the intervention can produce confusion and lack of adherence to the treatment from the patient. Even if the surgery is tailored to a patient's specific lesion, a unified consent form that discloses any possible extensions, including a total laryngectomy, is still needed. We reviewed the English literature on informed consent, and propose comprehensive Information and Consent Forms for OPHLs. The Information Form is intended to answer any possible questions about the procedure, while remaining easy to read and understand for the patient. It includes sections on laryngeal anatomy and physiology, surgical aims and indications, alternatives to surgery, complications, and physiology of the operated larynx. The Consent Form is written in a "modular" way: the surgeon defines the precise extension of the lesion, chooses the best OPHL procedure and highlights all possible expected extensions specific for the patient. Our intention, providing these forms both in Italian and in English, is to optimise communication between the patient and surgeon, improving surgical procedure arrangements and preventing any possible misunderstandings and medico-legal litigation.
