Management of Germ Cell Tumors During the Outbreak of the Novel Coronavirus Disease-19 Pandemic: A Survey of International Expertise Centers.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has become a public health emergency affecting frail populations, including patients with cancer. This poses the question of whether cancer treatments can be postponed or modified without compromising their efficacy, especially for highly curable cancers such as germ cell tumors (GCTs). MATERIALS AND METHODS: To depict the state-of-the-art management of GCTs during the COVID-19 pandemic, a survey including 26 questions was circulated by e-mail among the physicians belonging to three cooperative groups: (a) Italian Germ Cell Cancer Group; (b) European Reference Network-Rare Adult Solid Cancers, Domain G3 (rare male genitourinary cancers); and (c) Genitourinary Medical Oncologists of Canada. Percentages of agreement between Italian respondents (I) versus Canadian respondents (C), I versus European respondents (E), and E versus C were compared by using Fisher's exact tests for dichotomous answers and chi square test for trends for the questions with three or more options. RESULTS: Fifty-three GCT experts responded to the survey: 20 Italian, 6 in other European countries, and 27 from Canada. Telemedicine was broadly used; there was high consensus to interrupt chemotherapy in COVID-19-positive patients (I = 75%, C = 55%, and E = 83.3%) and for use of granulocyte colony-stimulating factor primary prophylaxis for neutropenia (I = 65%, C = 62.9%, and E = 50%). The main differences emerged regarding the management of stage I and stage IIA disease, likely because of cultural and geographical differences. CONCLUSION: Our study highlights the common efforts of GCT experts in Europe and Canada to maintain high standards of treatment for patients with GCT with few changes in their management during the COVID-19 pandemic. IMPLICATIONS FOR PRACTICE: Despite the chaos, disruptions, and fears fomented by the COVID-19 illness, oncology care teams in Italy, other European countries, and Canada are delivering the enormous promise of curative management strategies for patients with testicular cancer and other germ cell tumors. At the same time, these teams are applying safe and innovative solutions and sharing best practices to minimize frequency and intensity of patient contacts with thinly stretched health care capacity.

Prognostic significance of neutrophil-to-lymphocyte ratio in HPV status era for oropharyngeal cancer.

AIM: To evaluate the role of baseline neutrophil-to-lymphocyte ratio (NLR) as prognostic marker in squamous cell carcinoma of the oropharynx (OPC) treated with definitive chemoradiotherapy (CRT) in the era of HPV status. PATIENTS AND METHODS: A retrospective analysis of 125 patients (pts) affected with locally advanced OPC was performed. Inclusion criteria were age >18 years, stage III or IV (TNM 7th ed.) and definitive CRT. Haematological marker for their independent role as prognostic biomarkers for progression-free survival (PFS) and overall survival (OS). Logistic models were used to assess the association with downstage in TNM 8th ed. RESULTS: Seventy-seven (61.6%) pts had HPV/p16 + related OPC. Therapeutic choice consisted in sequential and concurrent CRT. Median follow-up was 50 months. A value of NLR ≥3 was associated with poorer OS. Two-year OS was 91% and 81% in pts with NLR <3 and ≥3, respectively. CONCLUSION: A baseline NLR ≥ 3 at treatment initiation represented a negative prognostic marker for OPC treated with definitive CRT. These results are in line with literature data, and prognostic value of NLR has been confirmed restaging our cohort with new TNM staging (8th ed.). Therefore, NLR could be considered a valuable biomarker for risk stratification in pts with OPC.

Predictors of Patient-Reported Dysphagia Following IMRT Plus Chemotherapy in Oropharyngeal Cancer.

The aim of this cross-sectional study is to evaluate the factors associated with patient-reported dysphagia in patients affected by locally advanced oropharyngeal cancer (OPC) treated with definitive intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy (CHT), with or without induction CHT. We evaluated 148 OPC patients treated with IMRT and concurrent CHT, without evidence of disease and who had completed their treatment since at least 6 months. At their planned follow-up visit, patients underwent clinical evaluation and completed the M.D. Anderson dysphagia inventory (MDADI) questionnaire. The association between questionnaire composite score (MDADI-CS) and different patients' and tumor's characteristics and treatments (covariates) was investigated by univariable and multivariable analyses, the latter including only covariates significant at univariable analysis. With a median time from treatment end of 30 months [range 6-74 months, interquartile range (IQR) 16-50 months], the median (IQR) MDADI-CS was 72 (63-84). The majority of patients (82.4%) had a MDADI-CS ≥ 60. At multivariable analysis, female gender, human papilloma virus (HPV)-negative status, and moderate and severe clinician-rated xerostomia were significantly associated with lower MDADI-CS. Patient-perceived dysphagia was satisfactory or acceptable in the majority of patients. HPV status and xerostomia were confirmed as important predictive factors for swallowing dysfunction after radiochemotherapy. Data regarding female gender are new and deserve further investigation.

Nutritional Intervention for Nonsurgical Head and Neck Cancer Patients Treated with Radiation Therapy: Results from a Prospective Stepped-Wedge Clinical Protocol.

AIM: To evaluate the impact on weight loss (WL) of a standardized nutritional stepped-wedge protocol on consecutive head and neck cancer (HNC) patients treated with curative radiotherapy (RT). METHODS: We prospectively collected data of patients followed by a trained dietitian and treated according to a pre-defined stepped-wedge protocol. Patients with swallowing defect at the baseline and WL >10% 3 months prior to the beginning of RT were excluded from the analysis. Nutritional status was assessed at the baseline and weekly during the course of RT. Fluid and caloric intake were assessed through a 24-h recall. RESULTS: Between May 2010 and March 2011, 42 patients treated were evaluated. Median overall treatment time was 52.5 days. WL per CTCAE 4.03 was G0, G1 and G2 in 23 (55%), 14 (33%) and 5 (12%) patients, respectively. Thirty-five (83%) patients did not require enteral nutrition. About 90% of patients completed RT without interruption of oral feeding. CONCLUSIONS: Despite the high toxicity profile of curative RT in HN, we proposed a standardized stepped-wedge protocol allowing to prevent severe WL in most of our patients. Further larger prospective studies are warranted to validate our approach and to achieve consensus on nutritional intervention in this subset of patients.

The outcome to axitinib or everolimus after sunitinib in metastatic renal cell carcinoma.

We aimed to investigate the different outcomes in patients with metastatic renal cell carcinoma treated with second-line axitinib or everolimus after sunitinib. Patients treated in 16 oncological centres in Italy were included, and those receiving axitinib or everolimus from January 2013 onwards were analysed for outcomes. Descriptive statistical tests were used to highlight differences between groups. The Kaplan-Meier method was used to estimate overall survival (OS) and progression-free survival (PFS). Data on 634 patients with metastatic renal cell carcinoma treated with first-line sunitinib have been obtained. A total of 182 patients received a second-line therapy with everolimus (79 patients, 43%) or axitinib (103 patients, 57%), respectively. The median PFS was 4.6 [95% confidence (CI): 2.6-6.5] months for patients treated with everolimus and 5.5 (95% CI: 4.3-6.7) months for patients treated with axitinib (P=0.7). The median OS was 13.9 (95% CI: 10.4-17.4) months for patients treated with everolimus and 12.0 (95% CI: 7.9-16.2) months for patients treated with axitinib (P=0.3). No differences were found based on length of first-line treatment. Major limitations are the retrospective nature of the study and the lack of a prospective evaluation of the progression. This study reports no significantly differences between everolimus and axitinib in terms of both PFS and OS. Furthermore, the length of first-line treatment cannot be used as such a predictive factor and cannot suggest the use of a molecule compared with another.

Prognostic role of the cumulative toxicity in patients affected by metastatic renal cells carcinoma and treated with first-line tyrosine kinase inhibitors.

Tyrosine kinase inhibitor-related toxicities have been reported to be predictive and/or prognostic factors in patients affected by metastatic renal cell carcinoma (mRCC). We aim to investigate the incidence of cumulative toxicity and its prognostic role in mRCC patients treated with sunitinib or pazopanib. mRCC patients treated with sunitinib or pazopanib at the European Institute of Oncology in Milan were reviewed for the incidence of adverse events. Cumulative toxicity was defined as the presence of more than one selected adverse event of any grade. Prognoses were evaluated by the International mRCC Database Consortium criteria. Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method and Cox analysis. A total of 104 patients were included in the final analysis. Only 18.3% did not experience any of the selected toxicities: 26.9% had one, 35.6% had two and 19.2% all three toxicities. Accordingly, 54.8% of patients experienced cumulative toxicity. In those with or without cumulative toxicity, the median PFS was 27.6 versus 7.2 months and the median OS was 61.2 versus 18.7 months, respectively. When cumulative toxicity was adjusted for International mRCC Database Consortium prognostic groups, it maintained its prognostic role for both PFS (hazard ratio: 0.31, 95% confidence interval, 0.20-0.49; P<0.001) and OS (hazard ratio: 0.27, 95% confidence interval, 0.15-0.48; P<0.001). A major limitation was the retrospective and monocentric nature of the analysis. We reported the prognostic role of cumulative toxicity because of hypertension, hypothyroidism and hand-foot syndrome in patients affected by mRCC and treated with sunitinib or pazopanib.

Combining standardized uptake value of FDG-PET and apparent diffusion coefficient of DW-MRI improves risk stratification in head and neck squamous cell carcinoma.

OBJECTIVES: To assess the independent prognostic value of standardized uptake value (SUV) and apparent diffusion coefficient (ADC), separately and combined, in order to evaluate if the combination of these two variables allows further prognostic stratification of patients with head and neck squamous cell carcinomas (HNSCC). METHODS: Pretreatment SUV and ADC were calculated in 57 patients with HNSCC. Mean follow-up was 21.3 months. Semiquantitative analysis of primary tumours was performed using SUVmaxT/B, ADCmean, ADCmin and ADCmax. The prognostic value of SUVmaxT/B, ADCmean, ADCmin and ADCmax in predicting disease-free survival (DFS) was evaluated with log-rank test and Cox regression models. RESULTS: Patients with SUVmaxT/B ≥5.75 had an overall worse prognosis (p = 0.003). After adjusting for lymph node status and diameter, SUVmaxT/B and ADCmin were both significant predictors of DFS with hazard ratio (HR) = 10.37 (95 % CI 1.22-87.95) and 3.26 (95 % CI 1.20-8.85) for SUVmaxT/B ≥5.75 and ADCmin ≥0.58 × 10-3 mm2/s, respectively. When the analysis was restricted to subjects with SUVmaxT/B ≥5.75, high ADCmin significantly predicted a worse prognosis, with adjusted HR = 3.11 (95 % CI 1.13-8.55). CONCLUSIONS: The combination of SUVmaxT/B and ADCmin improves the prognostic role of the two separate parameters; patients with high SUVmaxT/B and high ADCmin are associated with a poor prognosis. KEY POINTS: • High SUV maxT/B is a poor prognostic factor in HNSCC • High ADC min is a poor prognostic factor in HNSCC • In patients with high SUV maxT/B , high ADC min identified those with worse prognosis.

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.

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.

Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma in Older Patients: Are New Agents Bringing New Hope?

Head and neck cancer is a broad family of diseases, most of which are of squamous cell origin, affecting the epithelial mucosa lining the upper aerodigestive tract. They often recur or are progressive despite multimodality treatment approaches, resulting in a poor prognosis. Given the progressive aging of the global population, the probability to plan an active and eventually toxic treatment for an older patient, with either curative or palliative intent, can no longer be considered as an uncommon occurrence. A crucial point in offering a systemic treatment to older patients with head and neck squamous cell carcinoma is that they are underrepresented in randomised clinical trials, and evidence-based guidelines are lacking, while, from a clinical point of view, these patients may have varying grades of resilience to anticancer treatments due to differences in their health, social and/or economic status. Our aim is to draw attention to the older patient population suffering from recurrent and/or metastatic head and neck squamous cell carcinoma and to address some open questions, such as possible differences in epidemiology and biology compared with their younger counterparts; to highlight frailty and its components by discussing how to measure and use it to personalise treatment; to evaluate which outcomes should be best achieved in the older adult setting; finally, in the era of immunotherapy, to examine whether there are differences to be addressed when considering new treatments for older patients.

Long-lasting responses with chemotherapy followed by T-cell therapy in recurrent or metastatic EBV-related nasopharyngeal carcinoma.

Background: Refractory or metastatic nasopharyngeal carcinoma (NPC) patients have a poor prognosis due to the lack of effective salvage treatments and prolonged survival by means of combination chemotherapy being described only for a minority of younger patients with oligometastatic disease. Targeting the Epstein - Barr virus (EBV) proteins expressed in NPC cells has been shown to be a feasible strategy that could help control systemic disease. Patients and Methods: Between 2011 and 2014, 16 patients with recurrent/metastatic EBV-NPC received first-line chemotherapy (CT) followed by 2 doses of autologous cytotoxic EBV specific T-lymphocytes (15-25 x 107 total cells/dose, 2 weeks apart), based on our previous studies showing the feasibility and efficacy of this infusion regimen. Cumulative overall survival (OS) and median OS were analysed in the whole population and according to specific clinical and biological parameters. Results: All patients received the planned T-cell therapy schedule, 9 after reaching partial (n=5) or complete (n=4) disease remission with CT, and 7 after failing to obtain benefit from chemotherapy. No severe adverse events were recorded. Patients who received cytotoxic T-lymphocytes (CTLs) had a cumulative 10-year OS of 44%, with a median OS of 60 months (95% CI 42-62). Patients responding to CT, with oligometastatic disease (<3 disease sites), and plasma EBV-DNA <1000 copies/mL had a better outcome. Conclusions: Autologous EBV-specific CTLs transplanted following conventional first-line CT demonstrated promising efficacy with several patients obtaining long-lasting disease control. The rationale provided by this study, with the crucial role likely played by the timing of CTL administration when trying to induce synergy with conventional treatment needs to be confirmed in a prospective controlled trial.

Penile-Sparing Surgery for Tumour Recurrence after Previous Glansectomy/Partial Penectomy: Treatment Feasibility and Oncological Outcomes.

We tested the feasibility and oncological outcomes after penile-sparing surgery (PSS) for local recurrent penile cancer after a previous glansectomy/partial penectomy. We retrospectively analysed 13 patients (1997-2022) with local recurrence of penile cancer after a previous glansectomy or partial penectomy. All patients underwent PSS: circumcision, excision, or laser ablation. First, technical feasibility, treatment setting, and complications (Clavien-Dindo) were recorded. Second, Kaplan-Meier plots depicted overall and local recurrences over time. Overall, 11 (84.5%) vs. 2 (15.5%) patients were previously treated with glansectomy vs. partial penectomy. The median (IQR) time to disease recurrence was 56 (13-88) months. Six (46%) vs. two (15.5%) vs. five (38.5%) patients were treated with, respectively, local excision vs. local excision + circumcision vs. laser ablation. All procedures, except one, were performed in an outpatient setting. Only one Clavien-Dindo 2 complication was recorded. The median follow-up time was 41 months. Overall, three (23%) vs. four (30.5%) patients experienced local vs. overall recurrence, respectively. All local recurrences were safely treated with salvage surgery. In conclusion, we reported the results of a preliminary analysis testing safety, feasibility, and early oncological outcomes of PSS procedures for patients with local recurrence after previous glansectomy or partial penectomy. Stronger oncological outcomes should be tested in other series to optimise patient selection.

Hormone-receptor expression and activity of trastuzumab with chemotherapy in HER2-positive advanced breast cancer patients.

BACKGROUND: The relationship between quantitative immunohistochemical hormone receptor expression and response to the combination of trastuzumab with chemotherapy in HER2-positive advanced breast cancer is currently unknown. METHODS: Estrogen receptor (ER) and progesterone receptor expression was studied both as a dichotomous variable (positivity set at ≥ 1% of positive cells) and as a continuous variable. The effect of hormone receptor expression on overall response rate and progression-free survival in patients receiving trastuzumab-based treatment was studied by univariate and multivariate analysis. RESULTS: One hundred eleven of 227 consecutive advanced breast cancer patients treated at 2 Institutions had hormone receptor-positive tumors (49%). High expression of ER (≥ 30% of tumor cells) predicted reduced probability of tumor response to trastuzumab plus chemotherapy (multivariate odds ratio, 0.422; 95% confidence interval [CI], 0.222-0.803; P = .009). In patients with hormone receptor-positive tumors (≥ 1% of tumor cells), maintenance endocrine therapy added to trastuzumab upon the completion of chemotherapy was associated with a significant progression-free survival benefit (hazard ratio, 0.521; 95% CI, 0.3325-0.836; P = .007). CONCLUSIONS: Our results suggest a predictive role of hormone receptor expression in HER2-positive tumors. Further investigation in this patient subset is warranted to optimize the use of HER2-targeting agents, chemotherapy, and endocrine therapy.

Upfront transoral robotic surgery (TORS) versus intensity-modulated radiation therapy (IMRT) in HPV-positive oropharyngeal cancer: real-world data from a tertiary comprehensive cancer centre.

Objective: This study aims to provide real-world data on oncologic and functional outcomes of the most modern surgical and non-surgical treatments of locally advanced HPV-positive oropharyngeal cancer. Methods: We reviewed data on patients treated for stage III and IV HPV-positive oropharyngeal squamous cell carcinoma with either endoscopic surgery (Transoral Robotic Surgery, TORS; Transoral Laser Microsurgery, TLM - group A) or intensity-modulated radiotherapy (IMRT - group B). The minimum follow-up required was 6 months. Survival outcomes and toxicities of treatments were evaluated. Results: 30 patients in group A and 66 in group B were eligible for the analysis. 28% of patients in group A underwent a unimodal treatment, while 42% needed trimodal treatment. 90% of patients in group B underwent concurrent chemoradiation. We found no statistically significant difference in survival outcomes (group A: overall survival 97%, progression-free survival 83%; group B: OS 98%, PFS 86%) or toxicities between groups. Conclusions: Both transoral surgery and IMRT provide excellent outcomes in HPV-positive oropharyngeal cancer. Because of the good prognosis, treatments need to be refined to reduce toxicities while preserving oncologic soundness.

Oligometastatic Prostate Cancer: A Comparison between Multimodality Treatment vs. Androgen Deprivation Therapy Alone.

Background: We compared multimodality treatment (MMT, defined as robot-assisted radical prostatectomy (RARP) with androgen deprivation therapy (ADT), with or without adjuvant radiotherapy (RT)) vs. ADT alone in oligometastatic prostate cancer (OPC) patients. Methods: From 2010 to 2018, we identified 74 patients affected by cM1a-b OPC (≤5 metastases). Kaplan−Meier (KM) plots depicted cancer-specific mortality (CSM), disease progression, metastatic castration-resistant PC (mCRPC), and time to second-line systemic therapy rates. Multivariable Cox regression models (MCRMs) focused on disease progression and mCRPC. Results: Forty (54.0%) MMT and thirty-four (46.0%) ADT patients were identified. On KM plots, higher CSM (5.9 vs. 37.1%; p = 0.02), mCRPC (24.0 vs. 62.5%; p < 0.01), and second-line systemic therapy (33.3 vs. 62.5%; p < 0.01) rates were recorded in the ADT group. No statistically significant difference was recorded for disease progression. ForMCRMs adjusted for the metastatic site and PSA, a higher mCRPC rate was recorded in the ADT group. No statistically significant difference was recorded for disease progression. Treatment-related adverse events occurred in 5 (12.5%) MMT vs. 15 (44.1%) ADT patients (p < 0.01). Conclusions: MMT was associated with lower CSM, mCRPC, and second-line therapy rates. A lower rate of treatment-related adverse events was recorded for the MMT group.

Penile-sparing surgery for patients with superficial or initially invasive squamous cell carcinoma of the penis: long-term oncological outcomes.

PURPOSE: To report long-term oncological outcomes after penile-sparing surgery (PSS) for superficial (Ta-Tis) or initially invasive (T1) penile cancer patients. METHODS: We retrospectively analysed 85 patients with Ta/Tis/T1cN0cM0 penile cancer (1996-2018). All patients underwent PSS: circumcision, excision or laser ablation. First, Kaplan-Meier plots and multivariable Cox regression models tested tumor recurrence rates (any local/regional/metastatic). Second, Kaplan-Meier plots depicted progression-free survival (≥T2 or N1-3 or M1 disease). RESULTS: Median (IQR) follow-up time was 64 (48-95) months. Overall, 48 (56%) patients experienced tumor recurrence. Median (IQR) time to tumor recurrence was 34 (7-52) months. Higher recurrence rates were observed for Tis (65%) and T1 (64%), compared to Ta (40%), but these differences were not significant on multivariable Cox regression analyses (HR:2.0 with 95% CI [0.9-5.1] and HR:2.2 with 95% CI [0.9-5.9], respectively). Moreover, higher recurrence rates were observed for G2-3 tumors (74%), compared to G1 (57%), but these differences were not significant on multivariable Cox regression analyses (HR:1.6; 95% CI [0.8-3.2]). During follow-up, 15 (17.5%) vs. 18 (21.2%) vs. 10 (11.5%) patients underwent 1 vs. 2 vs. ≥3 PSS. Moreover, 26 (30.6%) and 4 (4.7%) men were treated with glansectomy and partial/total penile amputation due to local progression, tumor size or patient preference. Additionally, 24 (28%) men underwent invasive nodal staging. Last, 22 (25.9%) patients experienced disease progression. Median (IQR) time to disease progression was 51 (31-82) months. CONCLUSION: Patients treated with PSS for newly diagnosed superficial or initially invasive squamous cell carcinoma of the penis should be informed about the non-negligible risk of tumor recurrence and disease progression over time. In consequence, strict follow-up protocols are needed.

Therapeutic Sequences in the Treatment of High-Risk Prostate Cancer: Paving the Way Towards Multimodal Tailored Approaches.

Various definitions are currently in use to describe high-risk prostate cancer. This variety in definitions is important for patient counseling, since predicted outcomes depend on which classification is applied to identify patient's prostate cancer risk category. Historically, strategies for the treatment of localized high-risk prostate cancer comprise local approaches such as surgery and radiotherapy, as well as systemic approaches such as hormonal therapy. Nevertheless, since high-risk prostate cancer patients remain the group with higher-risk of treatment failure and mortality rates, nowadays, novel treatment strategies, comprising hypofractionated-radiotherapy, second-generation antiandrogens, and hadrontherapy, are being explored in order to improve their long-term oncological outcomes. This narrative review aims to report the current management of high-risk prostate cancer and to explore the future perspectives in this clinical setting.

Three weekly versus weekly concurrent cisplatin: safety propensity score analysis on 166 head and neck cancer patients.

BACKGROUND: Radio-chemotherapy with CDDP is the standard for H&N squamous cell cancer. CDDP 100 mg/m2/q3 is the standard; alternative schedules are used to reduce toxicity, mostly 40 mg/m2/q1. METHODS: Patients were treated from 1/2010 to 1/2017 in two Radiation Oncology Centres. Propensity score analysis (PS) was retrospectively used to compare these two schedules. RESULTS: Patients analyzed were 166. Most (114/166) had 1w-CDDP while 52 had 3w-CDDP. In the 3w-CDDP group, patients were younger, with better performance status, smaller disease extent and a more common nodal involvement than in the 1w-CDDP. Acute toxicity was similar in the groups. Treatment compliance was lower in the w-CCDP. Overall survival before PS was better for female, for oropharyngeal disease and for 3w-CDDP group. After PS, survival was not related to the CDDP schedule. CONCLUSIONS: 3w-CDDP remains the standard for fit patients, weekly schedule could be safely used in selected patients.

Survival Outcomes in Oral Tongue Cancer: A Mono-Institutional Experience Focusing on Age.

OBJECTIVE: The prognostic role of age among patients affected by Oral Tongue Squamous Cell Carcinoma (OTSCC) is a topic of debate. Recent cohort studies have found that patients diagnosed at 40 years of age or younger have a better prognosis. The aim of this cohort study was to clarify whether age is an independent prognostic factor and discuss heterogeneity of outcomes by stage and treatments in different age groups. METHODS: We performed a study on 577 consecutive patients affected by primary tongue cancer and treated with surgery and adjuvant therapy according to stage, at European Institute of Oncology, IRCCS. Patients with age at diagnosis below 40 years totaled 109 (19%). Overall survival (OS), disease-free survival (DFS), tongue specific free survival (TSFS) and cause-specific survival (CSS) were compared by age groups. Multivariate Cox proportional hazards models were used to assess the independent role of age. RESULTS: The median follow-up time was 5.01 years (range 0-18.68) years with follow-up recorded up to February 2020. After adjustment for all the significant confounding and prognostic factors, age remained independently associated with OS and DSF (respectively, p = 0.002 and p = 0.02). In CSS and TSFS curves, the role of age seems less evident (respectively, p = 0.14 and p = 0.0.37). In the advanced stage sub-group (stages III-IV), age was significantly associated with OS and CSS with almost double increased risk of dying (OS) and dying from tongue cancer (CSS) in elderly compared to younger groups (OS: HR = 2.16 95%, CI: 1.33-3.51, p= 0.001; CSS: HR = 1.76 95%, CI: 1.03-3.01, p = 0.02, respectively). In our study, young patients were more likely to be treated with intensified therapies (glossectomies types III-V and adjuvant radio-chemotherapy). Age was found as a prognostic factor, independently of other significant factors and treatment. Also the T-N tract involved by disease and neutrophil-to-lymphocyte ratio ≥3 were independent prognostic factors. CONCLUSIONS: Young age at diagnosis is associated with a better overall survival. Fewer younger people than older people died from tongue cancer in advanced stages.

Immunotherapy in Nonendemic Nasopharyngeal Carcinoma: Real-World Data from Two Nonendemic Regions.

BACKGROUND: nasopharyngeal carcinoma (NPC) is a complex disease entity that mainly predominates in endemic regions. Real-world data with immunotherapy from nonendemic regions are limited. METHODS: we collected data from patients with recurrent/metastatic (R/M) NPC treated at a center in Greece and 8 centers in Italy. Between 2016 and 2021, 46 patients who were treated with at least one cycle of immune checkpoint inhibitors (ICI) were identified. Herein, we present our results and a review of the literature. RESULTS: assessment of response was available in 42 patients. Overall, 11 patients responded to immunotherapy (Overall Response Rate-ORR 26.2%). Three patients had complete response (CR), and 8 patients had partial response (PR). Disease control rate (DCR) was 61.9%. Median Progression Free Survival (PFS) was 5.6 months and median Overall Survival (OS) was 19.1 months. Responders to ICI improved PFS and OS as compared to that of nonresponders. A lower probability of responding to ICI was shown in patients with more than three metastatic sites (p = 0.073), metastatic disease at initial diagnosis, (p = 0.039) or EBV DNA positive before ICI initiation, (p = 0.074). Decline in EBV DNA levels was found to be statistically significant associated with best response to ICI (p = 0.049). Safety was manageable. CONCLUSIONS: among 46 patients with R/M NPC treated with immunotherapy in two nonendemic regions, ORR was 26.2% and durable responses were observed. Low disease burden could serve as a biomarker for response to ICI.
