First-Line Selpercatinib or Chemotherapy and Pembrolizumab in RET Fusion-Positive NSCLC.

BACKGROUND: Selpercatinib, a highly selective potent and brain-penetrant RET inhibitor, was shown to have efficacy in patients with advanced RET fusion-positive non-small-cell lung cancer (NSCLC) in a nonrandomized phase 1-2 study. METHODS: In a randomized phase 3 trial, we evaluated the efficacy and safety of first-line selpercatinib as compared with control treatment that consisted of platinum-based chemotherapy with or without pembrolizumab at the investigator's discretion. The primary end point was progression-free survival assessed by blinded independent central review in both the intention-to-treat-pembrolizumab population (i.e., patients whose physicians had planned to treat them with pembrolizumab in the event that they were assigned to the control group) and the overall intention-to-treat population. Crossover from the control group to the selpercatinib group was allowed if disease progression as assessed by blinded independent central review occurred during receipt of control treatment. RESULTS: In total, 212 patients underwent randomization in the intention-to-treat-pembrolizumab population. At the time of the preplanned interim efficacy analysis, median progression-free survival was 24.8 months (95% confidence interval [CI], 16.9 to not estimable) with selpercatinib and 11.2 months (95% CI, 8.8 to 16.8) with control treatment (hazard ratio for progression or death, 0.46; 95% CI, 0.31 to 0.70; P<0.001). The percentage of patients with an objective response was 84% (95% CI, 76 to 90) with selpercatinib and 65% (95% CI, 54 to 75) with control treatment. The cause-specific hazard ratio for the time to progression affecting the central nervous system was 0.28 (95% CI, 0.12 to 0.68). Efficacy results in the overall intention-to-treat population (261 patients) were similar to those in the intention-to-treat-pembrolizumab population. The adverse events that occurred with selpercatinib and control treatment were consistent with those previously reported. CONCLUSIONS: Treatment with selpercatinib led to significantly longer progression-free survival than platinum-based chemotherapy with or without pembrolizumab among patients with advanced RET fusion-positive NSCLC.

Atezolizumab Plus Carboplatin and Etoposide in Patients with Untreated Extensive-Stage Small-Cell Lung Cancer: Interim Results of the MAURIS Phase IIIb Trial.

BACKGROUND: MAURIS is an Italian multicenter, open-label, phase IIIb ongoing trial, aiming at evaluating the safety and effectiveness of atezolizumab + carboplatin/etoposide in patients with newly diagnosed, extensive-stage small-cell lung cancer (ES-SCLC). The primary objective is the safety evaluation. MATERIALS AND METHODS: Patients received atezolizumab + carboplatin/etoposide Q3W for 4-6 cycles in the induction phase, followed by atezolizumab maintenance Q3W. We presented the interim analysis on safety (referring to the induction phase) and clinical effectiveness, in all patients (N = 154) and in subgroups that received ≤3 (N = 23), 4 (N = 43), and 5-6 cycles (N = 89) of induction. RESULTS: At a median follow-up of 10.5 months, 139 patients (90.3%) discontinued treatment. Serious adverse events occurred in 29.9% of patients overall, and the rate was lower in patients with 5-6 cycles (19.1%) than in those with 4 (34.9%) or ≤3 (63.6%) cycles. Immune-mediated adverse events were reported in 14.9%, 15.7%, 11.6%, and 18.2% of patients, overall and by subgroup, respectively. The median overall survival and progression-free survival were 10.7 and 5.5 months, respectively. Overall, 111 patients (71.6%) had a tumor response. CONCLUSIONS: Interim results provide further evidences about safety and efficacy profile of atezolizumab + carboplatin/etoposide treatment in a ES-SCLC patient population closer to that observed in clinical practice.

Effective retreatment with osimertinib in CNS-relapsed epidermal growth factor receptor-mutant non-small cell lung cancer patient following resection and adjuvant osimertinib.

For years, adjuvant chemotherapy has been the only standard treatment for resected non-small cell lung cancer patients (NSCLC), offering a dismal survival improvement at 5 years. Following the outstanding results of the recent ADAURA trial, osimertinib has become a new standard treatment for resected epidermal growth factor receptor (EGFR)-mutant non-squamous NSCLC, regardless of the administration of chemotherapy. For patients whose disease relapses after completion of the adjuvant therapy, there is no consensus about the optimal treatment. Herein, we report the case of a 74-year-old woman diagnosed with stage IIIA non-squamous NSCLC, harboring the EGFR p.L858R mutation. After complete tumor resection, the patient received adjuvant chemotherapy with cisplatin and vinorelbine, followed by osimertinib 80 mg daily for 3 years within the ADAURA trial. Brain disease relapse was documented 18 months after treatment completion by computed tomography scans. The patient was then retreated with osimertinib obtaining a deep intracranial partial response, which is still lasting after 21 months. The retreatment with osimertinib in patients whose disease relapsed following adjuvant therapy with the third-generation EGFR inhibitor might be a valid option, especially in patients with intracranial disease relapse. Studies are warranted to confirm this finding and to define the impact of the disease-free interval in this regard.

Adaptive Individualized high-dose preoperAtive (AIDA) chemoradiation in high-risk rectal cancer: a phase II trial.

PURPOSE: To evaluate the pathological complete response (pCR) rate of locally advanced rectal cancer (LARC) after adaptive high-dose neoadjuvant chemoradiation (CRT) based on 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG-PET/CT). METHODS: The primary endpoint was the pCR rate. Secondary endpoints were the predictive value of 18 F-FDG-PET/CT on pathological response and acute and late toxicity. All patients performed 18 F-FDG-PET/CT at baseline (PET0) and after 2 weeks during CRT (PET1). The metabolic PET parameters were calculated both at the PET0 and PET1. The total CRT dose was 45 Gy to the pelvic lymph nodes and 50 Gy to the primary tumor, corresponding mesorectum, and to metastatic lymph nodes. Furthermore, a sequential boost was delivered to a biological target volume defined by PET1 with an additional dose of 5 Gy in 2 fractions. Capecitabine (825 mg/m2 twice daily orally) was prescribed for the entire treatment duration. RESULTS: Eighteen patients (13 males, 5 females; median age 55 years [range, 41-77 years]) were enrolled in the trial. Patients underwent surgical resection at 8-9 weeks after the end of neoadjuvant CRT. No patient showed grade > 1 acute radiation-induced toxicity. Seven patients (38.8%) had TRG = 0 (complete regression), 5 (27.0%) showed TRG = 2, and 6 (33.0%) had TRG = 3. Based on the TRG results, patients were classified in two groups: TRG = 0 (pCR) and TRG = 1, 2, 3 (non pCR). Accepting p < 0.05 as the level of significance, at the Kruskal-Wallis test, the medians of baseline-MTV, interim-SUVmax, interim-SUVmean, interim-MTV, interim-TLG, and the MTV reduction were significantly different between the two groups. 18 F-FDG-PET/CT was able to predict the pCR in 77.8% of cases through compared evaluation of both baseline PET/CT and interim PET/CT. CONCLUSIONS: Our results showed that a dose escalation on a reduced target in the final phase of CRT is well tolerated and able to provide a high pCR rate.

Drug-induced colitis on BRAF and MEK inhibitors for BRAF V600E-mutated non-small cell lung cancer: a case report.

INTRODUCTION: The combination of BRAF and MEK inhibitors has deeply changed the treatment of BRAF V600-mutant non-small cell lung cancer patients. These agents demonstrated high antitumor activity as well as safe and manageable toxicity profile. Hypertension, pyrexia and increased liver enzymes are the most common adverse events. Gastrointestinal toxicities are rare, and mainly consist of mild grade vomiting and diarrhea. CASE REPORT: We report the case of 70-year-old man affected by BRAF V600-mutant NSCLC with bilateral lung and bone metastases. First-line treatment with encorafenib (450 mg once daily) and binimetinib (45 mg twice daily) was administered within a clinical trial. At the first radiological assessment, computed tomography (CT) scan showed a partial response and signs of intestinal inflammation were reported. The investigational treatment was timely withheld. The subsequent colonoscopy demonstrated the presence of ulcerative lesions at the caecal tract, and the histological diagnosis suggested a drug-induced colitis. No specific treatment was given as the patient did not report abdominal disturbances. Forty-five days after treatment interruption a new CT scan showed the resolution of bowel inflammation and investigational treatment was resumed at the same doses. The patient is still alive and free of toxicity recurrence after 11 months from treatment initiation. Conclusion. Severe gastrointestinal toxicities are uncommon with BRAF and MEK inhibitors, although cases of colitis and intestinal perforation have already been reported in literature. The pathogenesis seems to be related to the MAPK pathway inhibition performed by MEK inhibitors. These adverse events should be accounted given the potential to evolve into life-threatening conditions.

Platinum-based adjuvant chemotherapy for upper tract urothelial carcinoma: a change of paradigm? A meta-analysis of aggregate data.

We performed a systematic review and meta-analysis to evaluate the role of platinum-based adjuvant chemotherapy (AC) in upper tract urothelial carcinoma. Eligible studies were identified using Pubmed/Medline, Cochrane library, Embase and meeting abstracts. Outcomes of interest included: overall survival (OS), cancer-specific survival (CSS) and disease-free survival (DFS). Platinum-based AC was associated with improved DFS, while the benefit in OS and CSS was not statistically significant compared to observation. Conversely, platinum-based AC showed a modest OS benefit in an analysis combing multivariable HRs with estimated HRs from Kaplan-Meier curves. Our results suggest that platinum-based AC is associated with improved DFS and a modest OS benefit in patients with locally advanced urothelial carcinomas.

A phase II, open-label, single-arm trial of carboplatin plus etoposide with bevacizumab and atezolizumab in patients with extended-stage small-cell lung cancer (CeLEBrATE study): background, design and rationale.

Based on improved survival from the addition of PD-L1 inhibitors in phase III trials, the combination of immunotherapy and platinum-doublet chemotherapy has become the new standard treatment for extended-stage small-cell lung cancer (ES-SCLC). Furthermore, the antiangiogenetic agent bevacizumab showed a longer progression-free survival by targeting VEGF that has pleiotropic effects, including immunosuppressive ones. We, therefore, hypothesized that targeting angiogenesis would improve the efficacy of chemoimmunotherapy. The CeLEBrATE trial is an open-label, multicenter, phase II study designed to assess the efficacy and safety of the combination of carboplatin and etoposide plus bevacizumab and atezolizumab in treatment-naive patients with ES-SCLC. The primary end point is overall survival rate at 1 year, while secondary end points include overall response rate, progression-free survival and toxicity.

Lay abstract Extended-stage small-cell lung cancer (ES-SCLC) is a highly aggressive lung cancer subtype, accounting for 13­15% of all lung cancers. For several years, the standard treatment for this disease was based on polychemotherapy, with a rapid disease response but with an equally rapid disease progression. The new standard treatment has recently been changed, based on the results of two large clinical trials, which showed the efficacy and safety of the combination of chemotherapy with immunotherapy compared to chemotherapy alone. Nevertheless, prognosis of ES-SCLC remains poor, and new treatment strategies are urgently needed. Therefore, we designed the CeLEBrATE trial to investigate whether the combination of chemotherapy with antiangiogenetic therapy and immunotherapy is safe and could improve survival in patients with ES-SCLC.

Effects of benzydamine and mouthwashes containing benzydamine on Candida albicans adhesion, biofilm formation, regrowth, and persistence.

OBJECTIVES: To assess the effects of benzydamine and mouthwashes (MoWs) containing benzydamine on different stages of Candida albicans biofilm: adhesion, formation, persistence, and regrowth (if perturbed). MATERIALS AND METHODS: C. albicans CA1398, carrying the bioluminescence ACT1p-gLUC59 fusion product, was employed. Fungal cells were exposed for 1', 5', or 15' to 4 different benzydamine concentrations (0.075 to 0.6%) to 2 mouthwashes (MoWs) containing benzydamine and to a placebo MoW (without benzydamine). Treated cells were tested for adhesion (90 min) and biofilm formation (24-h assay). Next, 24- and 48-h-old biofilms were exposed to benzydamine and MoWs to assess regrowth and persistence, respectively. The effects of benzydamine, MoWs containing benzydamine, and placebo on different biofilm stages were quantified by bioluminescence assay and by the production of quorum sensing (QS) molecules. RESULTS: Benzydamine and MoWs containing benzydamine impaired C. albicans ability to adhere and form biofilm, counteracted C. albicans persistence and regrowth, and impaired a 48-h-old biofilm. Some of these effects paralleled with alterations in QS molecule secretion. CONCLUSIONS: Our results show for the first time that benzydamine and MoWs containing benzydamine impair C. albicans capacity to form biofilm and counteract biofilm persistence and regrowth. CLINICAL RELEVANCE: Benzydamine and MoWs containing benzydamine capacity to affect C. albicans biofilm provides an interesting tool to prevent and treat oral candidiasis. Likely, restraining C. albicans colonization through daily oral hygiene may counteract colonization and persistence by other critical oral pathogens, such as Streptococcus mutans, whose increased virulence has been linked to the presence of C. albicans biofilm.

Impact of Baseline Versus Intercurrent Steroids Administration on Upfront Chemo-Immunotherapy for Advanced Non-Small Cell Lung Cancer (NSCLC).

The impact of baseline versus intercurrent steroids on the efficacy of upfront chemotherapy plus pembrolizumab (CT-ICI) for advanced non-small cell lung cancer (NSCLC) patients is unclear. We conducted a retrospective study on metastatic NSCLC patients treated with upfront CT-ICI at our institution between March 2020 and December 2021. The use of steroids was considered as the administration of at least 10 mg of prednisone equivalent. Of 101 patients, 36 (35.6%) received steroid therapy at baseline, and 18 (17.8%) started steroids on treatment. Overall, median progression-free survival (mPFS) was 6.5 months (95% CI, 5.9−8.9) and median overall survival (mOS) was 18.2 months (95% CI, 8.9-NR). Patients taking baseline steroids had significantly shorter survival than those not taking them and those assuming intercurrent steroids (mPFS 5.0 vs. 9.2 vs. 7.3 months, p < 0.001; mOS 7.0 months vs. not reached, p < 0.001). Baseline steroids were significantly associated with poorer survival outcomes in the multivariate model (OS HR 2.94, p = 0.02; PFS HR 3.84, p > 0.001). Conversely, intercurrent prescription did not reach a significant value regardless of other pivotal variables included in the model. Baseline steroid administration was associated with a detrimental effect on survival outcomes in NSCLC patients treated with CT-ICI. The role of intercurrent steroid administration should be further explored in larger studies.

Bone fracture as a novel immune-related adverse event with immune checkpoint inhibitors: Case series and large-scale pharmacovigilance analysis.

Although immune checkpoint inhibitors (ICIs) are associated with different immune-related adverse events (irAEs), the potential effect on the skeleton is poorly defined albeit biologically plausible and assessable through pharmacovigilance. We described a case series of patients experiencing skeletal fractures while on ICIs at the National Cancer Institute of Milan. To better characterize the clinical features of skeletal irAEs reported with ICIs, we queried the FDA Adverse Event Reporting System (FAERS) and performed disproportionality analysis by means of reporting odds ratios (RORs), deemed significant by a lower limit of the 95% confidence interval (LL95% CI) > 1. Bone AEs emerging as significant were scrutinized in terms of demographic and clinical data, including concomitant irAEs or drugs affecting bone resorption or causing bone damage. Four patients with skeletal events while on ICIs were included in our case series, of which three exhibited vertebral fractures. In FAERS, 650 patients with bone and joint injuries and treated with ICIs were retrieved, accounting for 822 drug-event pairs. Statistically significant ROR was found for eight, two and one bone AEs respectively with PD-1, PD-L1 and CTLA-4 inhibitors, being pathological fracture (N = 46; ROR = 3.17; LL95%CI = 2.37), spinal compression fracture (42; 2.51; 1.91), and femoral neck fracture (26; 2.38; 1.62) the most common. Concomitant irAEs or drugs affecting bone metabolism were poorly reported. The increased reporting of serious vertebral fractures in patients without concomitant irAEs and no apparent preexisting risk factors could suggest a possible cause-effect relationship and calls for close clinical monitoring and implementation of dedicated guidelines.

Cyclin-dependent kinase 4/6 inhibitors and interstitial lung disease in the FDA adverse event reporting system: a pharmacovigilance assessment.

PURPOSE: We assessed pulmonary toxicity of cyclin-dependent kinase (CDK)4/6 inhibitors by analyzing the publicly available FDA Adverse Event Reporting System (FAERS). METHODS: Reports of interstitial lung disease (ILD) were characterized in terms of demographic information, including daily dose, latency, concomitant drugs known to be associated with ILD, and causality assessment (adapted WHO system). Disproportionality analyses were carried out by calculating reporting odds ratios (RORs) with 95% confidence interval (CI), accounting for major confounders, including notoriety and competition biases. RESULTS: ILD reports (N = 161) represented 2.1% and 0.3% of all reports for abemaciclib and palbocilcib/ribociclib, respectively, with negligible proportion of concomitant pneumotoxic drugs. Increased reporting was found for CDK4/6 inhibitors when compared to other drugs (ROR = 1.50; 95%CI = 1.28-1.74), and abemaciclib vs other anticancer agents (4.70; 3.62-5.98). Sensitivity analyses confirmed a strong and consistent disproportionality for abemaciclib. Higher-than-expected reporting emerged for palbociclib (1.38; 1.07-1.77) and ribociclib (2.39; 1.34-3.92) only when removing Japan reports. ILD occurred at recommended daily doses, with median latency ranging from 50 (abemaciclib) to 253 (ribociclib) days. Causality was highly probable in 55% of abemaciclib cases, probable in 68% of palbociclib cases. CONCLUSIONS: Increased reporting of ILD with CDK4/6 inhibitors calls for further comparative population-based studies to characterize and quantify the actual risk, taking into account drug- and patient-related risk factors. These findings strengthen the role of (a) timely pharmacovigilance to detect post-marketing signals through FAERS and other real-world data, (b) clinicians to assess early, on a case-by-case basis, the potential responsibility of CDK4/6 inhibitors when diagnosing a lung injury.

Single-agent carboplatin in extensive disease small-cell lung cancer patient with liver failure: a case report within the experience of a single institution.

Until recently, platinum-based chemotherapy has represented the benchmark for the treatment of extensive disease small-cell lung cancer (ED-SCLC). ED-SCLC patients are often diagnosed with poor performance status (PS ≥2) and/or compromised organ functions. In fact, up to 63% of ED-SCLC has extensive liver involvement at diagnosis, which correlates with a poor prognosis. Whether to treat patients with tumor-related organ failure is still debated and the selection of those who could benefit from chemotherapy is crucial. Moreover, severe liver impairment contraindicates the administration of etoposide. Among 74 consecutive ED-SCLC patients followed at our institution from January 2017 to November 2019, three patients received single-agent carboplatin as a first-line treatment due to liver failure. We provide a brief description of a former heavy smoker 70-year-old man who was diagnosed with ED-SCLC and severe liver involvement leading to liver failure. The patient received a first-line treatment with single-agent carboplatin, obtaining a partial response, clinical benefit and the normalization of laboratory test, which documented the complete recovery of liver function. The intent of our work is to highlight the feasibility of single-agent carboplatin in ED-SCLC patients with tumor-related hepatic failure but preserved Eastern Cooperative Oncology Group PS, suggesting that this therapeutic option should not be discouraged a priori. Indeed, the identification of specific tools guiding physicians in the selection of patients who might benefit from the treatment is remarkably needed; meanwhile, the use of available prognostic score (e.g. Manchester score) might be of great value and should be considered in clinical practice.

Prognostic and predictive factors to nivolumab in patients with metastatic renal cell carcinoma: a single center study.

Renal cell carcinoma (RCC) scenario has radically changed with the advent of immunotherapy; in this setting, the identification of predictive and prognostic factors represents an urgent clinical need to evaluate which patients are the best candidate for an immunotherapy approach. The aim of our study was to analyze the association between nivolumab in pretreated patients with metastatic RCC and clinicopathological features, metastatic sites, and clinical outcomes. A total of 37 patients treated between January 2017 and April 2020 in our institution were retrospectively evaluated. All patients received nivolumab as second- or later-line of therapy after progression on previous tyrosine kinase inhibitors. The primary outcomes were overall survival (OS) from immunotherapy start and OS from first-line start. Univariate analysis was performed through the log-rank test and a Cox regression proportional hazards model was employed in multivariable analysis. Of the 12 variables analyzed, 4 were significantly associated with prognoses at multivariate analysis. Cox proportional hazard ratio models confirmed that International Metastatic Renal-Cell Carcinoma Database Consortium (IMDC) risk group, liver metastases at diagnosis, and central nervous system (CNS) metastases at diagnosis were associated with worse OS with an estimated hazard ratio of 4.76 [95% confidence interval (CI), 2.05-19.8] for liver metastases and 2.27 (95% CI, 1.13-28.9) for CNS metastases. Pancreatic metastases at diagnosis were correlated to a better prognosis with an estimated hazard ratio of 0.15 (95% CI, 0.02-0.38). IMDC risk group, liver metastases at diagnosis, and CNS metastases at diagnosis may identify a population of patients treated with immunotherapy in second- or later-line associated with worse prognosis.

PD-(L)1 inhibitors as single-agent or in combination with chemotherapy for advanced, PD-L1-high non-small cell lung cancer: a meta-analysis.

Introduction: The best treatment for advanced, PD-L1-high non-small-cell lung cancer remains a debated issue. Methods: A meta-analysis of randomized clinical trials (RCTs) was performed to compare the efficacy and safety of PD-(L)1 inhibitors alone or plus chemotherapy (CT) for advanced, PD-L1-high non-small-cell lung cancer. Results: 14 RCTs were included. The combination of a PD-(L)1 inhibitor with CT resulted in the improvement of progression-free survival (HR: 0.59; 95% CI: 0.43-0.79; p = 0.0005) and objective response rate (RR: 1.66; 95% CI: 1.14-2.42; p = 0.008). No overall survival difference was documented (HR: 0.99; 95% CI: 0.77-1.27; p = 0.95). The risk of grade ≥3 treatment-related adverse events was significantly reduced with immune-checkpoint inhibitor single-agent therapy compared with immune-checkpoint inhibitors plus CT (RR: 0.38; 95% CI: 0.32-0.45; p = 0.00001). Conclusion: The combination of a PD-(L)1 inhibitor and CT appears to be associated with improved PFS and ORR, but similar OS, compared with PD-(L)1 inhibitor single-agent therapy in patients with PD-L1-high non-small-cell lung cancer.

Quality of life assessment in renal cell carcinoma Phase II and III clinical trials published between 2010 and 2020: a systematic review.

Aims: Quality of life (QoL) assessment is frequently not included among the end points of clinical trials (CTs) on renal cell carcinoma. Herein we aimed to describe the assessment and reporting of QoL in Phase II and Phase III CTs published between 2010 and 2020. Methods: A total of 25 CTs were included; 76% of trials included were conducted in metastatic renal cell carcinoma patients, while 20% of studies evaluated adjuvant systemic treatments. Results: In 13/25 publications, QoL was not listed among the end points, with secondary publications dedicated to QoL present in a minority of cases. Conclusions: QoL was not included among the end points of a large percentage of CTs. Implementing the inclusion of QoL represents an urgent need.

Lay abstract Recent years have seen growing attention toward quality of life (QoL) in medical oncology clinical trials and statistical measurement of this aspect of cancer treatment. Nonetheless, although most clinicians and researchers agree that QoL should represent a fundamental component of clinical trials, the inclusion of QoL results is still inadequate, and our systematic review confirms that implementing the inclusion of QoL remains an urgent need.

Phase 2 study of NAB-paclitaxel in SensiTivE and refractory relapsed small cell lung cancer (SCLC) (NABSTER TRIAL).

BACKGROUND: Despite sensitivity to first-line chemotherapy, most small-cell lung cancer (SCLC) patients relapse. In this setting, topotecan demonstrated modest activity with significant toxicity. Paclitaxel was also active. This study was designed to evaluate activity and safety of nab-paclitaxel in relapsed SCLC. METHODS: In this multicentre prospective Phase 2 trial, patients with refractory or sensitive SCLC progressed to first-line platinum-based chemotherapy received nab-paclitaxel 100 mg/smq on days 1, 8, 15 every 4 weeks up to six cycles, progressive disease or intolerable toxicity. Primary endpoint was investigator-assessed objective tumour response. Secondary endpoints were toxicity, progression-free survival (PFS) and overall survival (OS). RESULTS: Of the 68 patients treated, partial response was 8% in the refractory cohort and 14% in the sensitive cohort. Most common toxicities of any grade were fatigue (54%), anaemia (38%), neutropenia (29%), leukopenia (26%) and diarrhoea (21%). Median PFS was similar in both refractory (1.8 months) and sensitive cohorts (1.9 months), while median OS was longer in sensitive one (6.6 versus 3.6 months). CONCLUSIONS: Although nab-paclitaxel has shown some modest anti-tumour activity in relapsed SCLC, associated with a favourable toxicity profile, the primary end-point of the study was not met. CLINICAL TRIAL REGISTRATION: Clinical Trial registration number is ClinicalTrials.gov Identifier: NCT03219762.

Randomized Pilot Trial of Percutaneous Posterior Tibial Nerve Stimulation Versus Medical Therapy for the Treatment of Low Anterior Resection Syndrome: One-Year Follow-up.

BACKGROUND: Low anterior resection syndrome is significantly associated with a deterioration in the quality of life, and its medical treatment is usually ineffective. OBJECTIVE: The aim of the present study was to establish the efficacy of percutaneous tibial nerve stimulation in treating this syndrome. DESIGN: This is a randomized pilot trial with 1-year follow-up. SETTINGS: The study was conducted in a specialized colorectal unit of a tertiary hospital. PATIENTS: Patients who underwent neoadjuvant chemoradiotherapy and low anterior rectal resection for cancer with low anterior resection syndrome score ≥21 and ileostomy closed at least 18 months earlier were included. INTERVENTIONS: Patients were randomly assigned to receive either percutaneous tibial nerve stimulation plus medical treatment (arm A, n = 6) or medical treatment (arm B, n = 6). Low anterior resection syndrome was assessed using symptom severity and disease-specific quality-of-life scores at baseline, at the end of treatment, and at 1-year follow-up. MAIN OUTCOME MEASURES: The primary outcome was a clinical response, defined as a reduction of the low anterior resection syndrome score. RESULTS: Only in group A low anterior resection syndrome score, fecal incontinence severity index, and obstructed defecation syndrome score improved significantly with treatment (35.8 ± 2.5 vs 29.0 ± 3.8 (p = 0.03); 36.8 ± 4.3 vs 18.5 ± 8.0 (p = 0.02); 10.3 ± 3.9 vs 8.0 ± 4.9 (p = 0.009)) and changes were observed in all domains of quality-of-life instruments. In both groups the symptom severity and quality-of-life scores at 1-year follow-up did not differ significantly from those recorded at the end of treatment. LIMITATIONS: The study had a small number of patients and it was underpowered to detect the within-group effect. CONCLUSIONS: Percutaneous tibial nerve stimulation could be an effective treatment for low anterior resection syndrome. Additional studies are warranted to investigate clinical effectiveness in low anterior resection syndrome. See Video Abstract at http://links.lww.com/DCR/B371. ESTUDIO PILOTO ALEATORIO DE ESTIMULACIÓN PERCUTÁNEA DEL NERVIO TIBIAL POSTERIOR VERSUS TERAPIA MÉDICA PARA EL TRATAMIENTO DEL SÍNDROME DE RESECCIÓN ANTERIOR BAJA: UN AÑO DE SEGUIMIENTO: El síndrome de resección anterior baja se asocia con un deterioro significativo en la calidad de vida y su tratamiento médico generalmente es ineficaz.El objetivo del presente estudio fue establecer la eficacia de la estimulación percutánea del nervio tibial en el tratamiento de este síndrome.Este es un estudio piloto aleatorio con 1 año de seguimiento.El estudio se realizó en una unidad colorrectal especializada de un hospital terciario.Se incluyeron pacientes que se sometieron a quimiorradioterapia neoadyuvante y resección rectal anterior baja por cáncer con puntaje de síndrome de resección anterior baja ≥ 21 e ileostomía cerrada al menos 18 meses antes.Los pacientes fueron asignados aleatoriamente para recibir estimulación percutánea del nervio tibial + tratamiento médico (brazo A, n = 6) o tratamiento médico (brazo B, n = 6). El síndrome de resección anterior baja se evaluó utilizando puntajes de la gravedad de los síntomas y de calidad de vida específicos de la enfermedad al inicio, al final del tratamiento y al año de seguimiento.El resultado primario fue una respuesta clínica, definida como una reducción de la puntuación del síndrome de resección anterior baja.Solo en el grupo A, el puntaje del síndrome de resección anterior baja, el índice de severidad de incontinencia fecal y el puntaje del síndrome de defecación obstruida mejoraron significativamente con el tratamiento (35.8 ± 2.5 vs 29 ± 3.8, p = 0.03; 36.8 ± 4.3 vs 18.5 ± 8.0, p = 0.02; 10.3 ± 3.9 vs 8.0 ± 4.9, p = 0.009, respectivamente) y se observaron cambios en todos los dominios de los instrumentos de calidad de vida. En ambos grupos, los puntajes de severidad de los síntomas y de calidad de vida al año de seguimiento no difirieron significativamente de los registrados al final del tratamiento.El estudio tuvo un pequeño número de pacientes y no logró suficiente poder para detectar el efecto dentro de grupo.La estimulación percutánea del nervio tibial podría ser un tratamiento efectivo para el síndrome de resección anterior baja. Se requieren estudios adicionales para investigar la efectividad clínica en el síndrome de resección anterior baja. Consulte Video Resumen http://links.lww.com/DCR/B371.

Third- and later-line treatment in advanced or metastatic gastric cancer: a systematic review and meta-analysis.

Aim: We performed a systematic review and meta-analysis to investigate the efficacy and safety of third-line (TLT) and salvage treatment (ST) in advanced or metastatic gastric cancer. Materials & methods: Eligible studies included randomized clinical trials assessing TLT and ST versus placebo or best supportive care. Outcomes of interest included: overall survival, objective response rate and disease control rate in TLT; progression-free survival in ST; grade 3-4 adverse events in ST. Results: The use of TLT and ST was superior to placebo or best supportive care in terms of prolonging overall survival and progression-free survival. Hematological toxicities were more frequent in ST. Conclusion: TLT and ST are considerable and tolerable treatment options for patients with advanced or metastatic gastric cancer. Given the substantial heterogeneities affecting the efficacy analyses, these results have to be interpreted cautiously.

Fighting cancer in coronavirus disease era: organization of work in medical oncology departments in Emilia Romagna region of Italy.

Aim: To assess the measures applied to reduce the spread of coronavirus disease (COVID-19) and the timing of their application in medical oncology departments. Materials & methods: We surveyed all medical oncology departments from the Italian Emilia Romagna region via a multidomain questionnaire. The questions covered items on patients, healthcare workers, risk reduction measure and clinical trials. Results: A total of 12 centers involving 861 healthcare members joined the survey. The measures applied to patients and health workers partially converged in all the departments while major divergences were found in the clinical trials domain. High rate of COVID-19 infection occurred among medical doctors (21/208, 10.1%) and social care workers (13/110, 11.8%). Rate of infection among nurses was 5.7% (24/418). Conclusion: All measures able to reduce risk of COVID-19 infection must be applied in medical oncology departments. Early introduction of risk reduction measures may be a critical issue.

Quality of life with second or third line nab-paclitaxel-based regimens in advanced non-small-cell lung cancer.

Aim: Evaluate quality of life (QoL) in patients with advanced non-small cell lung cancer treated with second or third line nab-paclitaxel ± durvalumab. Patients & methods: Longitudinal QoL was assessed using Lung Cancer Symptom Scale, EuroQoL Five-Dimensions Five-Levels and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire 30-item core. Results: QoL was generally stable through eight treatment cycles (both arms). Clinically meaningful improvement from baseline was noted in Lung Cancer Symptom Scale (overall constitutional score and three-item index [nab-paclitaxel + durvalumab]) and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire 30-item core (global health status/QoL and emotional functioning [both arms] and pain [nab-paclitaxel + durvalumab]) analyses. EuroQoL Five-Dimensions Five-Levels domains were stable/improved or completely resolved at least once in 19-56% and 9-51% of patients, respectively. Conclusion: While QoL trends were promising, additional data are required to support these regimens in this setting.
