Impact of the pandemic on surgical oncology in Piedmont, Italy: A retrospective observational study.

BACKGROUND AND METHODS: This retrospective observational study analyzes how the COVID-19 pandemic affected surgical oncology healthcare in a large sample from Piedmont, Northern Italy. Patients admitted for regular hospitalization were included (n = 99 651). Data from 2020 were compared to the averages from 2016 to 2019, stratified by tumor site, year, month, and admission method, using interrupted time series analysis post-March 2020. RESULTS: In 2020, oncological surgeries decreased by 12.3% (n = 17 923) compared to the 2016-2019 average (n = 20 432), notably dropping post-March (incidence rate ratio = 0.858; p < 0.001). The greatest reduction was observed for breast (-19.2%), colon (-18.2%), bladder (-17.5%), kidney (-14.2%), and prostate (-14%) surgeries. There was a huge reduction in nonemergency admissions (-13.6%), especially for colon (-23.8%), breast (-19.4%), and bladder (-18.7%). The proportion of hospitalizations with emergency access increased (p < 0.001). CONCLUSIONS: The COVID-19 pandemic led to a significant decrease in cancer surgeries in Piedmont in 2020, with an increase in the proportion of admissions through emergency access. DISCUSSION: The research provides valuable insights for comparing data with other regions and evaluating the effectiveness of efforts to recover lost surgical procedures. These findings can be useful to policymakers in developing coordinated measures and more efficient access strategies to healthcare services in any future emergency situations.

Treatment of bone metastases from solid tumors with bone-modifying agents: a web survey of Italian oncologists investigating patterns of practice drug prescription and prevention of side effects.

PURPOSE: Optimal use of bone-modifying agents (BMAs) in patients with bone metastases from solid tumors is uncertain in some aspects: the drug choice; the planned treatment duration and long-term therapy; the prevention and management of possible side effects, including renal toxicity, hypocalcaemia, and medication-related osteonecrosis of the jaw (MRONJ). METHODS: Italian oncologists were invited to fulfil a 24-question web survey about prescription of BMAs for bone metastases of breast cancer, prostate cancer, and other solid tumors. Prevention and management of side effects were also investigated. RESULTS: Answers of 191 oncologists were collected. BMAs are usually prescribed at the time of diagnosis of bone metastases by 87.0% (breast cancer) and 76.1% (solid tumors except breast and prostate cancers) of oncologists; the decision is more articulated for prostate cancer (endocrine-sensitive versus castration-resistant). The creatinine level (32.3%), the availability of patient venous access (15.8%), and the type of primary neoplasm (13.6%) are the most reported factors involved in choice between bisphosphonates and denosumab. Zoledronic acid every 3 months was considered as a valid alternative to monthly administration by 94% of Italian oncologists. Oncologists reported a good confidence with measures aimed to prevent MRONJ, whereas uncertainness about prevention and management of hypocalcemia was registered. CONCLUSION: Italian oncologists showed a high attitude in prescribing bisphosphonates or denosumab at the time of diagnosis of bone metastases, with a large application of preventive measures of side effects. Further studies are needed to investigate some controversial aspects, such as optimal drug treatment duration and long-term drug schedules.

Eribulin in brain metastases of breast cancer: outcomes of the EBRAIM prospective observational trial.

Background: Eribulin shows some activity in controlling brain metastasis in breast cancer. Methods: This observational, multicenter study evaluated brain disease control rates, survival and safety in patients with brain metastatic breast cancer treated with eribulin in clinical practice. Results: A total of 34 patients were enrolled (mean age 49 years, 91% with visceral metastases) and 29 were evaluable for brain disease. Fourteen achieved disease control and showed a longer time without progression: 10 months (95% CI: 2.3-17.7) versus 4 months (95% CI: 3.3-4.7) in the control group (p = 0.029). Patients with clinical benefits at 6 months had longer survival. Leukopenia and neutropenia were the most frequent grade 3-4 toxicities. Conclusion: Eribulin confirms its effectiveness in patients with brain metastatic breast cancer. Further studies on larger cohorts are needed to confirm the results.

Trastuzumab-related cardiotoxicity in patients with nonlimiting cardiac comorbidity.

BACKGROUND: Significant and symptomatic cardiac comorbidity is a contraindication to adjuvant trastuzumab in breast cancer patients. However, some patients with asymptomatic, nonlimiting cardiac comorbidity and normal baseline left ventricular ejection fraction (LVEF) receive adjuvant trastuzumab in the clinical practice. We sought to describe the tolerability of trastuzumab in these patients. PATIENTS AND METHODS: Retrospective analysis of patients with baseline asymptomatic, nonlimiting cardiac comorbidity receiving adjuvant trastuzumab at six Institutions between July 2007 and January 2016. RESULTS: Thirty-seven patients with HER2-positive, surgery treated breast cancer at high risk of relapse were studied. Median age was 64 years (range 36-82), median baseline LVEF 61% (range 50%-85%). Thirteen patients (35%) received trastuzumab with adjuvant anthracycline and taxane-based regimens, 19 (51%) with taxane-based, three (8%) with off-label vinorelbine and two (5%) with off-label endocrine therapy. Most frequent cardiac comorbidities were ischemic heart disease (35%), valvular disease (30%), atrial fibrillation (19%), and conduction disorders (14%). Nine patients (24.3%) experienced a cardiac event: congestive heart failure (one patient, 3%), asymptomatic LVEF reduction (six patients, 16%), and rhythm disturbances (two patients, 5%). Trastuzumab had to be discontinued either permanently (five patients, 14%) or temporarily (two patients, 5%). At the time of last follow-up visit, all patients showed LVEF within normal limits, except one who had experienced a symptomatic cardiac event (LVEF value at last follow-up 46%). CONCLUSIONS: Caution is needed in patients with significant ongoing cardiovascular risk factors, but when adjuvant trastuzumab is deemed beneficial on breast cancer outcomes, nonlimiting cardiac comorbidity should not preclude treatment.

Optimal Ki67 cut-off for luminal breast cancer prognostic evaluation: a large case series study with a long-term follow-up.

Although Ki67 index suffers from poor reproducibility, it is one of the most important prognostic markers used by oncologists to select the treatment of estrogen receptor (ER) positive breast cancer patients. In this study, we aim to establish the optimal Ki67 cut-offs for stratifying patient prognosis and to create a comprehensive prognostic index for clinical applications. A mono-institutional cohort of 1.577 human epidermal growth factor receptor 2 negative/ER+ breast cancer patients having complete clinical, histological, and follow-up data was collected. The 14 and 20 % Ki67 cut-offs were correlated to disease-free interval (DFI) and disease-specific survival (DSS). To create a comprehensive prognostic index, we used independent variables selected by uni/multivariate analyses. In terms of DFI and DSS, patients bearing tumors with Ki67 < 14 % proliferation index did not differ from those with Ki67 values between 14 and 20 %. Patients with tumor with Ki67 > 20 % showed the poorest prognosis. Moreover, to tumor size, the number of metastatic lymph nodes and Ki67 > 20 % was given a score value, varying depending on definite cut-offs and used to create a prognostic index, which was applied to the population. Patients with a prognostic index ≥3 were characterized by significant risk of relapse [DFI: Hazard Ratio (HR) = 4.74, p < 0.001] and death (DSS: HR = 5.03, p < 0.001). We confirm that the 20 % Ki67 cut-off is the best to stratify high-risk patients in luminal breast cancers, and we suggest to integrate it with other prognostic factors, to better stratify patients at risk of adverse outcome.

Prevention and treatment of oral mucositis in patients with head and neck cancer treated with (chemo) radiation: report of an Italian survey.

PURPOSE: There is a limited number of therapies with a high level of recommendations for mucositis, while several strategies are currently employed with a limited evidence for efficacy. A national survey among Italian oncologists who treat head and neck cancer (HNC) was conducted in order to assess the most common preventive and therapeutic protocols (including nutritional support and pain control) for oral mucositis (OM) in patients undergoing chemoradiotherapy. METHODS: From September to November 2012, a nationwide electronic survey with 21 focused items was proposed to chemotherapy and radiotherapy centers. RESULTS: We collected 111 answers. Common Terminology Criteria for Adverse Events (CTCAE) scale is employed by 55% of the physicians in assessing mucosal toxicity. The most relevant predictive factors for OM development are considered smoke, alcohol use, planned radiotherapy, and concurrent use of radiosensitizing chemotherapy. Prophylactic gastrostomy is adopted in <10% of the patients. Preventive antibiotics or antimycotics are prescribed by 46% of the responders (mainly local or systemic antimycotic drugs). Alkalinizing mouthwashes or coating agents are frequently adopted (70% of the cases). Among therapeutic interventions, systemic fluconazole is administered by 80% of the physicians. Pain is mainly treated by weak followed by strong opioids. CONCLUSIONS: A variety of preventive and therapeutic protocols for OM exists among the participating Italian centers, with some uniformity in respect to nutritional support, use of antimycotic and painkillers. There is an urgent need for well-conducted clinical trials aimed at assessing the best choices for OM prevention and treatment in HNC.

Conventional 2D (2DRT) and 3D conformal radiotherapy (3DCRT) versus intensity-modulated radiotherapy (IMRT) for nasopharyngeal cancer treatment.

PURPOSE: Nasopharyngeal carcinoma represents a distinct entity as compared to other head and neck tumours. Radio-chemotherapy is the treatment of first choice in non-metastatic disease. Intensity-modulated radiation therapy (IMRT) allows the sparing of parotid glands, improving the toxicity profile. The aim of this study was to compare the results obtained with IMRT with those obtained with conventional 2D (2DRT) and 3D conformal radiation therapy (3DCRT) in terms of tumour control, survival, acute and late toxicity. MATERIALS AND METHODS: We reviewed the clinical records of 52 patients with histologically proven carcinoma of the nasopharynx (stage I-IVB according to the 2002 American Joint Committee on Cancer staging system) treated with curative intent between January 2003 and August 2011: 26 patients were treated with 2D or 3D technique (arm A) and 26 with IMRT technique (arm B) with simultaneous integrated boost. Fifty patients (96 %) received chemotherapy. Local control (LC), locoregional control (LRC), disease-free survival (DFS), overall survival (OS), acute and late toxicity were retrospectively evaluated. RESULTS: After a median follow-up of 37.6 months (69 months in arm A and 23 months in arm B), 69 % of patients were alive and disease-free, 10 % were alive with disease and 21 % died of disease, with an OS of 81 % at 2 years and 79 % at 5 years, a LC rate of 88 % at 2 years and 78 % at 5 years, a LRC rate of 80 % at 2 years and 73 % at 5 years and a DFS of 74 % at 2 years and 65 % at 5 years, with no statistically significant differences between IMRT and 2DRT/3DCRT. In multivariate analysis, the TNM stage and the volume treated at high dose correlated with DFS. No factor was found to be related to OS. Chronic toxicity was not statistically different in the two study groups and in particular ≥ G2 xerostomia rates were 67 and 41 % in arm A and B, respectively (p = 0.10). CONCLUSIONS: The findings of this study confirm that IMRT associated with chemotherapy, even with moderately hypofractionated regimens, allows good disease control with better results in terms of late xerostomia, although without statistically significant differences compared to 2DRT and 3DCRT. The hypothesis of an impact of IMRT on survival has yet to be confirmed.

Association of a gene-expression subtype to outcome and treatment response in patients with recurrent/metastatic head and neck squamous cell carcinoma treated with nivolumab.

BACKGROUND: Immune checkpoint inhibitors have been approved and currently used in the clinical management of recurrent and metastatic head and neck squamous cell carcinoma (R/M HNSCC) patients. The reported benefit in clinical trials is variable and heterogeneous. Our study aims at exploring and comparing the predictive role of gene-expression signatures with classical biomarkers for immunotherapy-treated R/M HNSCC patients in a multicentric phase IIIb trial. METHODS: Clinical data were prospectively collected in Nivactor tiral (single-arm, open-label, multicenter, phase IIIb clinical trial in platinum-refractory HNSCC treated with nivolumab). Findings were validated in an external independent cohort of immune-treated HNSCC patients, divided in long-term and short-term survivors (overall survival >18 and <6 months since the start of immunotherapy, respectively). Pretreatment tumor tissue specimen from immunotherapy-treated R/M HNSCC patients was used for PD-L1 (Tumor Proportion Score; Combined Positive Score (CPS)) and Tumor Mutational Burden (Oncopanel TSO500) evaluation and gene expression profiling; classical biomarkers and immune signatures (retrieved from literature) were challenged in the NIVACTOR dataset. RESULTS: Cluster-6 (Cl6) stratification of NIVACTOR cases in high score (n=16, 20%) and low score (n=64, 80%) demonstrated a statistically significant and clinically meaningful improvement in overall survival in the high-score cases (p=0.00028; HR=4.34, 95% CI 1.84 to 10.22) and discriminative ability reached area under the curve (AUC)=0.785 (95% CI 0.603 to 0.967). The association of high-score Cl6 with better outcome was also confirmed in: (1) NIVACTOR progression-free survival (p=4.93E-05; HR=3.71, 95% CI 1.92 to 7.18) and objective-response-rate (AUC=0.785; 95% CI 0.603 to 0.967); (2) long survivors versus short survivors (p=0.00544). In multivariate Cox regression analysis, Cl6 was independent from Eastern Cooperative Oncology Group performance status, PDL1-CPS, and primary tumor site. CONCLUSIONS: These data highlight the presence of underlying biological differences able to predict survival and response following treatment with immunotherapy in platinum-refractory R/M HNSCC that could have translational implications improving treatment selection.

TEAM Study: Upfront Docetaxel Treatment in Patients With Metastatic Hormone-Sensitive Prostate Cancer: A Real-World, Multicenter, Retrospective Analysis.

BACKGROUND: Treatment of metastatic hormone-sensitive prostate cancer (mHSPC) dramatically changed. PEACE-1 and ARASENS trials established triplet therapy efficacy. Identifying prognostic factors supporting treatment choice is pivotal. METHODS: TEAM is an observational, retrospective study to evaluate prognostic role of variables in mHSPC patients receiving upfront docetaxel in 11 Italian centers. Outcome measures were progression-free survival (PFS) and overall-survival (OS). RESULTS: From September 2014 to December 2020, 147 patients were included. Median PFS and OS were 11.6 and 37.4 months. At univariate analysis, PFS-related variables were Gleason Score (GS) (P = .001), opioid use (P = .004), bone metastases number (P < .001), baseline PSA (P = .006), Hb (P < .001), ALP (P < .001) and LDH (P = .002), time between ADT and docetaxel start (P = .018), 3-month PSA (P < .001) and ALP (P < .001), and number of docetaxel cycles (P < .001). OS-related variables were PSA at diagnosis (P = .024), primary tumor treatment (P = .022), baseline pain (P = .015), opioid use (P < .001), bone metastases number (P < . 001), baseline Hb (P < .001), ALP (P < .001) and LDH (P = .001), NLR ratio (P = .039), 3-month PSA (P < .001) and ALP (P < .001) and docetaxel cycles number (P < .001). At multivariate analysis, independent prognostic variables were GS, opioid use, baseline LDH and time between ADT and docetaxel initiation for PFS, and baseline Hb and LDH for OS. CONCLUSION: Patients receiving upfront docetaxel with high GS, high disease burden, pain or opioid use, baseline unfavorable laboratory values had worse outcomes. Patients had greater docetaxel benefit when initiated early after ADT start. These parameters could be taken into account when selecting candidates for triplet therapy.

The oligometastatic setting in HNSCC: A critical review by the Rete Oncologica Piemonte e Valle d'Aosta multidisciplinary team.

INTRODUCTION: The oligometastatic disease is a low burden metastatic disease that might still benefit from curable treatment. Squamous cell carcinoma of the head and neck (HNSCC) is a complex group of malignancies, with high rates of loco-regional recurrences. Distant metastases are less frequent, and a single or few deposits are often observed (oligometastatic disease). The optimal management of oligometastatic HNSCC remains to be defined. MATERIALS AND METHODS: Key references were derived from a PubMed query. Hand searching and clinicaltrials.gov were also used. RESULTS: This paper contains a narrative report and a critical discussion of the available evidence on the management of oligometastatic HNSCC patients, with a focus on metastasis-directed therapy (MDT), particularly stereotactic ablative radiotherapy (SABR). CONCLUSIONS: in line with literature data, the multidisciplinary evaluation emerged as the key element in the management of oligometastatic HNSCC patients.

First-line treatment of metastatic castration-resistant prostate cancer: the real-world Italian cohort of the Prostate Cancer Registry.

BACKGROUND: With the availability of multiple treatment options for metastatic castration-resistant prostate cancer (mCRPC), new real-world data on disease management and drugs' performance are needed. METHODS: We described characteristics, management and clinical outcomes of patients receiving first-line mCRPC treatment within the Italian cohort of the real-world, prospective, international Prostate Cancer Registry. Patients were enrolled consecutively (2013-2016) in 32 Italian sites and followed for 3 years. RESULTS: 238 patients were included: 157 received first-line abiraterone acetate plus prednisone ("abiraterone" thereafter) and 70 first-line docetaxel; 11 patients receiving other treatments were not considered. Compared with docetaxel-treated patients, those receiving abiraterone were significantly older (age ⩾75: 63.7% vs 38.6%), less frequently had a Gleason score >8 (48.2% vs 67.6%, p<0.005) at initial diagnosis, and more frequently an ECOG score ⩾1 (52.7% vs 36.2%, p<0.05) and comorbidities (76.4% vs 57.1%, p<0.05) at baseline; they reported a lower analgesic use (15.3% vs 30%, p<0.005). In the abiraterone group (median follow-up 22.1 months), median time to progression (TTP) and progression-free survival (PFS) were, respectively, 14.4 months (95% confidence interval, CI, 10.6-18.0) and 13.0 months (95% CI, 9.1-16.8); median overall survival (OS) was not reached, and 3-year OS was 59.1%. In the docetaxel treatment group (median follow-up 25.3 months), median TTP, PFS and OS were, respectively, 8.2 months (95% CI, 6.1-10.3), 8.2 months (95% CI, 5.8-10.3) and 33.2 months (95% CI, 19.2-not estimable). CONCLUSION: This investigation provided valuable information on the overall mCRPC treatment pattern and the effectiveness of first-line abiraterone and docetaxel in a population representative of everyday practice.

Sinonasal Side Effects of Chemotherapy and/or Radiation Therapy for Head and Neck Cancer: A Literature Review.

Radiotherapy and chemotherapy represent important treatment modalities for head and neck cancer. Rhinosinusitis and smell alterations are common side effects in the sinonasal region. This review will summarize and analyze our current knowledge of the sinonasal side effects of chemotherapy and/or radiation therapy for head and neck cancer (HNC), with a specific focus on mucosal and olfactory disorders. A review of the English literature was performed using several databases (PubMed, Embase, Cochrane, Scopus). Fifty-six articles were included in qualitative synthesis: 28 assessed mucosal disorders (rhinitis or rhinosinusitis), 26 evaluated olfactory alterations, and 2 articles addressed both topics. The incidence and severity of olfactory dysfunction and chronic rhinosinusitis were highest at the end of radiotherapy and at three months after treatment and decreased gradually over time. Smell acuity deterioration and chronic rhinosinusitis seemed to be related to radiation dose on olfactory area and nasal cavities, but different degrees of recovery were observed. In conclusion, it is important to establish the severity of chronic rhinosinusitis and olfactory dysfunction in order to find strategies to support patients and improve their quality of life.

Macrophages expressing TREM-1 are involved in the progression of HPV16-related oropharyngeal squamous cell carcinoma.

INTRODUCTION: Many types of research have been performed to improve the diagnosis, therapy, and prognosis of oropharyngeal carcinomas (OP-SCCs). Since they arise in lymphoid-rich areas and intense lymphocytic infiltration has been related to a better prognosis, a TREM-1 putative function in tumour progression and survival has been hypothesized. MATERIALS AND METHODS: Twenty-seven human papillomavirus (HPV) 16+ OP-SCC specimens have been analyzed to relate TREM-1 expression with histiocytic and lymphocytic markers, HPV presence and patients' outcome. RESULTS: No differences have been shown between intratumoral and stromal CD4+ cells, while intratumoral CD8+ lymphocytes are higher with respect to the tumour stroma (p = .0005). CD68+ cells are more than CD35+ and TREM-1+; their presence is related to CD35± and TREM-1± histiocytes (p = .005 and .026, respectively). Intratumoral CD4+ lymphocytes are higher in p16+ cases (11/27) than in p16- (p = .042); moreover, p16 positivity correlates to a better survival (p = .034). CD4+, CD8+ and CD35+ cells have no impact on survival, while CD68 expression heavily influences progression and bad outcome (p = .037). TREM-1 positivity also leads to worst overall survival (p = .001): peritumoral expression and death-cause relationship are always significant, particularly when the cause is OP-SCC (p = .000). CONCLUSION: While p16 shows to better stratify HPV16+ patients' outcome, TREM-1+ macrophages suggest their key importance in HPV-related OP-SCCs progression.KEY MESSAGESTREM-1 positivity correlates to the worst overall survival of HPV16-positive OPSCCs-affected patients.p16-positive HPV16 related OPSCCs patients have a better prognosis with respect to p16-negative ones.

Effectiveness of a Psychosocial Care Quality Improvement Strategy to Address Quality of Life in Patients With Cancer: The HuCare2 Stepped-Wedge Cluster Randomized Trial.

Importance: Many patients with cancer who would benefit from psychosocial care do not receive it. Implementation strategies may favor the integration of psychosocial care into practice and improve patient outcomes. Objective: To evaluate the effectiveness of the Humanization in Cancer Care (HuCare) Quality Improvement Strategy vs standard care as improvement of at least 1 of 2 domains (emotional or social function) of patient health-related quality of life at baseline and 3 months. A key secondary aim included investigation of the long-term effect. Design, Setting, and Participants: HuCare2 was a multicenter, incomplete, stepped-wedge cluster randomized clinical trial, conducted from May 30, 2016, to August 28, 2019, in three 5-center clusters of cancer centers representative of hospital size and geographic location in Italy. The study was divided into 5 equally spaced epochs. Implementation sequence was defined by a blinded statistician; the nature of the intervention precluded blinding for clinical staff. Participants included consecutive adult outpatients with newly diagnosed cancer of any type and stage starting medical cancer treatment. Interventions: The HuCare Quality Improvement Strategy comprised (1) clinician communication training, (2) on-site visits for context analysis and problem-solving, and (3) implementation of 6 evidence-based recommendations. Main Outcomes and Measures: The primary outcome was the difference between the means of changes of individual scores in emotional or social functions of health-related quality of life detected at baseline and 3-month follow-up (within each group) and during the postintervention epoch compared with control periods (between groups). Long-term effect of the intervention (at 12 months) was assessed as a secondary outcome. Intention-to-treat analysis was used. Results: A total of 762 patients (475 [62.3%] women) were enrolled (400 HuCare Quality Improvement Strategy and 362 usual care); mean (SD) age was 61.4 (13.1) years. The HuCare Quality Improvement Strategy significantly improved emotional function during treatment (odds ratio [OR], 1.13; 95% CI, 1.04-1.22; P = .008) but not social function (OR, 0.99; 95% CI, 0.89-1.09; P = .80). Effect on emotional function persisted at 12 months (OR, 1.05; 95% CI, 1.00-1.10; P = .04). Conclusions and Relevance: In this trial, the HuCare Quality Improvement Strategy significantly improved the emotional function aspect of health-related quality of life during cancer treatment and at 12 months, indicating a change in clinician behavior and in ward organization. These findings support the need for strategies to introduce psychosocial care; however, more research is needed on factors that may maximize the effects.

A CT-Based Radiomic Signature Can Be Prognostic for 10-Months Overall Survival in Metastatic Tumors Treated with Nivolumab: An Exploratory Study.

Baseline clinical prognostic factors for recurrent and/or metastatic (RM) head and neck squamous cell carcinoma (HNSCC) treated with immunotherapy are lacking. CT-based radiomics may provide additional prognostic information. A total of 85 patients with RM-HNSCC were enrolled for this study. For each tumor, radiomic features were extracted from the segmentation of the largest tumor mass. A pipeline including different feature selection steps was used to train a radiomic signature prognostic for 10-month overall survival (OS). Features were selected based on their stability to geometrical transformation of the segmentation (intraclass correlation coefficient, ICC > 0.75) and their predictive power (area under the curve, AUC > 0.7). The predictive model was developed using the least absolute shrinkage and selection operator (LASSO) in combination with the support vector machine. The model was developed based on the first 68 enrolled patients and tested on the last 17 patients. Classification performance of the radiomic risk was evaluated accuracy and the AUC. The same metrics were computed for some baseline predictors used in clinical practice (volume of largest lesion, total tumor volume, number of tumor lesions, number of affected organs, performance status). The AUC in the test set was 0.67, while accuracy was 0.82. The performance of the radiomic score was higher than the one obtainable with the clinical variables (largest lesion volume: accuracy 0.59, AUC = 0.55; number of tumoral lesions: accuracy 0.71, AUC 0.36; number of affected organs: accuracy 0.47; AUC 0.42; total tumor volume: accuracy 0.59, AUC 0.53; performance status: accuracy 0.41, AUC = 0.47). Radiomics may provide additional baseline prognostic value compared to the variables used in clinical practice.

Nasopharyngeal cancer in non-endemic areas: Impact of treatment intensity within a large retrospective multicentre cohort.

AIM: Recommendations for managing patients with nasopharyngeal carcinoma (NPC) in non-endemic areas are largely derived from studies conducted in endemic areas. We analysed the impact of treatment approaches on survival in non-endemic areas. METHODS: In an international, multicentre, retrospective study, we analyse consecutive patients with NPC diagnosed between 2004 and 2017 in 36 hospitals from 11 countries. Treatment was categorised as non-intensive (NIT), including radiotherapy alone or concomitant chemoradiotherapy (cCRT), and intensive (IT) including cCRT preceded by and/or followed by chemotherapy (CT). The impact of IT on overall survival (OS) and disease-free survival (DFS) was adjusted for all the available potential confounders. RESULTS: Overall, 1021 and 1113 patients were eligible for overall survival (OS) and disease-free survival (DFS) analyses, respectively; 501 and 554 with Epstein Barr-encoded RNA (EBER) status available. In the whole group, 5-year OS was 84% and DFS 65%. The use of NIT was associated with a risk of death or recurrence 1.37 times higher than patients receiving IT. Patients submitted to NIT and induction CT + concurrent concomitant chemo and three-dimensional Conformal Radiation Therapy (3DCRT) had a risk of death or recurrence 1.5 and 1.7 times higher than patients treated with induction CT + cCRT with intensity-modulated radiotherapy (IMRT), respectively. The IT had no impact on OS in neither patients with EBER+ nor in patients with EBER-; IT showed better DFS in EBER+ but not in patients with EBER-. CONCLUSIONS: In low-incidence areas, patients with NPC treated with induction CT followed by concurrent IMRT cCRT achieved the highest DFS rate. The benefit of IT on DFS was restricted to patients with EBER+, suggesting that additional therapy offers no advantages in EBER- cases.

Cardioprotective Strategy for Patients With Nonmetastatic Breast Cancer Who Are Receiving an Anthracycline-Based Chemotherapy: A Randomized Clinical Trial.

IMPORTANCE: Several studies have evaluated cardioprotective strategies to prevent myocardial dysfunction in patients who are receiving cardiotoxic therapies. However, the optimal approach still represents a controversial issue. OBJECTIVE: To determine whether pharmacological cardioprevention could reduce subclinical heart damage in patients with breast cancer who are being treated with anthracycline-based chemotherapy. DESIGN, SETTING, AND PARTICIPANTS: The SAFE trial was a 4-arm, randomized, phase 3, double-blind, placebo-controlled, national multicentric study conducted at 8 oncology departments in Italy. It was a prespecified interim analysis on the first 174 patients who had completed cardiac assessment at 12 months. The study recruitment was conducted between July 2015 and June 2020. The interim analysis was performed in 2020. Patients were eligible for trial inclusion if they had indication to receive primary or postoperative systemic therapy using an anthracycline-based regimen. Patients with a prior diagnosis of cardiovascular disease were excluded. INTERVENTIONS: Cardioprotective therapy (bisoprolol, ramipril, or both drugs compared with placebo) was administered for 1 year from the initiation of chemotherapy or until the end of trastuzumab therapy in case of ERBB2-positive patients. Doses for all groups were systematically up-titrated up to the daily target dose of bisoprolol (5 mg, once daily), ramipril (5 mg, once daily), and placebo, if tolerated. MAIN OUTCOMES AND MEASURES: The primary end point was defined as detection of any subclinical impairment (worsening ≥10%) in myocardial function and deformation measured with standard and 3-dimensional (3D) echocardiography, left ventricular ejection fraction (LVEF), and global longitudinal strain (GLS). RESULTS: The analysis was performed on 174 women (median age, 48 years; range, 24-75 years) who had completed a cardiological assessment at 12 months and reached the end of treatment. At 12 months, 3D-LVEF worsened by 4.4% in placebo arm and 3.0%, 1.9%, 1.3% in the ramipril, bisoprolol, ramipril plus bisoprolol arms, respectively (P = .01). Global longitudinal strain worsened by 6.0% in placebo arm and 1.5% and 0.6% in the ramipril and bisoprolol arms, respectively, whereas it was unchanged (0.1% improvement) in the ramipril plus bisoprolol arm (P < .001). The number of patients showing a reduction of 10% or greater in 3D-LVEF was 8 (19%) in the placebo arm, 5 (11.5%) in the ramipril arm, 5 (11.4%) in the bisoprolol, arm and 3 (6.8%) in the ramipril plus bisoprolol arm; 15 patients (35.7%) who received placebo showed a 10% or greater worsening of GLS compared with 7 (15.9; ramipril), 6 (13.6%; bisoprolol), and 6 (13.6%; ramipril plus bisoprolol) (P = .03). CONCLUSIONS AND RELEVANCE: The interim analysis of this randomized clinical trials suggested that cardioprotective pharmacological strategies in patients who were affected by breast cancer and were receiving an anthracycline-based chemotherapy are well tolerated and seem to protect against cancer therapy-related LVEF decline and heart remodeling.

A multidisciplinary expert opinion on CINV and RINV, unmet needs and practical real-life approaches.

Introduction: A range of combination chemotherapy regimens are currently used in clinical practice. However, international antiemetic guidelines often only categorize the emetogenic potential of single agents rather than the emetogenicity of combination chemotherapy regimens. To manage the nausea and vomiting induced by antineoplastic combinations, guidelines suggest antiemetics that are appropriate for the component drug with the highest emetogenic potential. Furthermore, antiemetic guidelines generally do not consider the influence of other factors, including individual patient characteristics, on the emetic effects of cancer treatments. Similarly, the emetogenic potential of radiotherapy is stratified only according to the site of radiation, while other factors contributing to emetic risk are overlooked.Areas covered: An Expert Panel was convened to examine unresolved issues and summarize the current clinical research on managing nausea and vomiting associated with combination chemotherapy and radiotherapy.Expert opinion: The panel identified the incidence of nausea and vomiting induced by multi-drug combination therapies currently used to treat cancer at different anatomic sites and by radiotherapy in the presence of other risk factors. Based on these data and the clinical experience of panel members, several suggestions are made for a practical approach to prevent or manage nausea and vomiting due to chemotherapy regimens and radiation therapy.

Effectiveness of abiraterone acetate plus prednisone in chemotherapy-naïve patients with metastatic castration-resistant prostate cancer in a large prospective real-world cohort: the ABItude study.

BACKGROUND: Real-world data on chemotherapy-naïve patients with metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone plus prednisone are limited, largely deriving from small retrospective studies. METHODS: ABitude is an Italian, observational, prospective, multicenter study of mCRPC patients receiving abiraterone plus prednisone in clinical practice. Chemotherapy-naïve mCRPC patients were consecutively enrolled at abiraterone start (February 2016 to June 2017) and are being followed for 3 years, with evaluation approximately every 6 months. Several clinical and patients reported outcomes were examined. RESULTS: In this second interim analysis, among 481 enrolled patients, 453 were evaluable for analyses. At baseline, the median age was 77 years and ~69% of patients had comorbidities (mainly cardiovascular diseases). Metastases were located mainly at bones and lymph nodes; 8.4% of patients had visceral metastases. During a median follow-up of 18 months, 1- and 2-year probability of radiographic progression-free survival were 73.9% and 56.2%, respectively; the corresponding rates for overall survival were 87.3% and 70.4%. In multivariable analyses, the number of bone metastases significantly affected radiographic progression-free survival and overall survival. During abiraterone plus prednisone treatment, 65% of patients had a ⩾50% prostate-specific antigen decline, and quality of life remained appreciably high. Among symptomatic patients according to the Brief Pain Inventory) (32%), scores significantly declined after 6 months of treatment. Overall, eight patients (1.7%) had serious adverse reactions to abiraterone. CONCLUSIONS: Abiraterone plus prednisone is effective and safe for chemotherapy-naïve mCRPC patients in clinical practice.

Breakthrough Cancer Pain Clinical Features and Differential Opioids Response: A Machine Learning Approach in Patients With Cancer From the IOPS-MS Study.

PURPOSE: A large proportion of patients with cancer suffer from breakthrough cancer pain (BTcP). Several unmet clinical needs concerning BTcP treatment, such as optimal opioid dosages, are being investigated. In this analysis the hypothesis, we explore with an unsupervised learning algorithm whether distinct subtypes of BTcP exist and whether they can provide new insights into clinical practice. METHODS: Partitioning around a k-medoids algorithm on a large data set of patients with BTcP, previously collected by the Italian Oncologic Pain Survey group, was used to identify possible subgroups of BTcP. Resulting clusters were analyzed in terms of BTcP therapy satisfaction, clinical features, and use of basal pain and rapid-onset opioids. Opioid dosages were converted to a unique scale and the BTcP opioids-to-basal pain opioids ratio was calculated for each patient. We used polynomial logistic regression to catch nonlinear relationships between therapy satisfaction and opioid use. RESULTS: Our algorithm identified 12 distinct BTcP clusters. Optimal BTcP opioids-to-basal pain opioids ratios differed across the clusters, ranging from 15% to 50%. The majority of clusters were linked to a peculiar association of certain drugs with therapy satisfaction or dissatisfaction. A free online tool was created for new patients' cluster computation to validate these clusters in future studies and provide handy indications for personalized BTcP therapy. CONCLUSION: This work proposes a classification for BTcP and identifies subgroups of patients with unique efficacy of different pain medications. This work supports the theory that the optimal dose of BTcP opioids depends on the dose of basal opioids and identifies novel values that are possibly useful for future trials. These results will allow us to target BTcP therapy on the basis of patient characteristics and to define a precision medicine strategy also for supportive care.
