RESUMEN
Lung cancer is the most frequent cause of cancer-related death worldwide and is usually diagnosed in advanced stages. Among those, approximately 7.4% of non-small cell lung cancer (NSCLC) patients will have brain metastasis (BM) at presentation, and 25-30% will develop BM during the course of their disease. To date, patients with BMs are increasingly considered for combined treatment using systemic immune checkpoint inhibition (ICI) and cranial radiation therapy (RT); yet, there is limited data regarding the safety of this approach. Here, we report two cases of NSCLC patients treated with two different types of cranial RT and ICIs.

Oral mucositis is among the most common tissue toxicities associated with both cytotoxic cancer regimens and head and neck radiotherapy. Current management of oral mucositis might comprise growth factors and cytokines, anti-inflammatory agents, anesthetics, analgesics, antimicrobial and coating agents, cryotherapy and mucosal protectants. Despite its long history and its impact on patients, there are currently no effective options for the prevention or treatment of mucositis. In recent years, more attention has been focused on the role of natural drugs. Verbascoside belongs to the phenylpropanoid glycosides family. Several biological properties have been described, such as anti-inflammatory, antimicrobial, antitumor and antioxidant. Verbascoside, particularly when in solution with polyvinylpyrrolidone and sodium hyaluronate, thanks to barrier effect, is useful in re-epithelialization and in reducing pain, oral mucositis score, burning and erythema.

Neurofibromatosis type 2 (NF2) is an autosomal dominant condition caused by pathogenic variants in the NF2 gene. To date, cytotoxic chemotherapy has no established role in the treatment of NF-2. Historical case reports of malignant schwannomas have documented responses to chemotherapies with cyclophosphamide, vincristine and doxorubicin, in patients who develop pulmonary metastases. Recently, several studies proposed the use of anti-HER2, anti-EGFR, anti-platelet-derived growth factor receptors. As reported in our previous review of the literature, vascular endothelial growth factor (VEGF) and its receptor VEGFR-1 have been detected in schwannomas with the best results. We described the case of a young patient with NF2 treated for long time with Bevacizumab. Here, we report the update of the previous case report.

Renal cell carcinoma (RCC) is one of the most frequent malignancies of the adults. Its incidence has been increasing steadily by 2-4% each year. Up to 30% of patients present with metastases at diagnosis. It is a highly vascularized cancer because of the hypoxia-induced factor stabilization as a consequence of von Hippel-Lindau inactivation. Hypoxia-induced factor accumulation leads to transactivation of molecules involved in angiogenesis including vascular endothelial growth factor (VEGF) and platelet-derived growth factor. Sunitinib is an oral tyrosine kinase inhibitor that interacts with several angiogenesis receptors including platelet-derived growth factor receptors and VEGF receptors, and is approved for the first-line treatment in metastatic RCC. In terms of tolerability, patients treated with sunitinib showed a higher incidence of diarrhea, vomiting, hypertension, hand-foot syndrome, and neutropenia, a safety profile consistent with what had been observed in earlier phase studies. Axitnib is a potent and selective tyrosine kinase inhibitor of VEGF receptors 1, 2, and 3, and is approved in the second-line setting for patients with metastatic RCC. The tolerability profile of axitinib is favorable. The most commonly reported treatment-related adverse events are diarrhea, hypertension, fatigue, nausea, and dysphonia. Bowel toxicity, especially pneumatosis intestinalis and bowel perforation, is very uncommon. In particular, the incidence of intestinal perforation or fistulae is not well known for sunitinib or axitinib. Here, for the first time, we report the incidence of rectovaginal fistula in a 57-year-old White woman, with RCC, following treatment with sunitinib and axitinib.

Neurofibromatosis type 2 (NF-2) is an autosomal dominant inherited disease caused by heterozygous mutations in the NF-2 tumor suppressor gene. It is characterized by the development of multiple benign tumors in the central nervous system. A majority of these tumors can be treated with surgery or radiotherapy in the case of the symptomatic disease. Cytotoxic chemotherapy has no established role in the treatment of NF-2. Vascular endothelial growth factor (VEGF) is a critical mediator of tumor angiogenesis and vessel permeability. VEGF and its receptor VEGFR-1 have been detected in schwannomas, and increased levels of these factors correlate with increased rates of tumor growth. The use of bevacizumab has made many progresses in recent years in NF-2 patients. We report a case of a young patient treated with more than 100 administration of bevacizumab, with clinical and instrumental benefits.

PURPOSE: Sinonasal tumours are rare diseases with poor prognosis. Multimodal approach including surgery is widely used, although no standard therapy has been established in prospective trials. This study assessed activity and safety of an innovative integration of multimodality treatment-induction chemotherapy (ICT), surgery and radiotherapy (RT)-modulated by histology and response to ICT. METHODS: Patients with untreated, operable sinonasal tumours with selected histotypes (squamous cell carcinoma, intestinal-type adenocarcinoma, sinonasal undifferentiated and neuroendocrine carcinoma, olfactory neuroblastoma) were enrolled in a single-arm, phase II, multicenter clinical trial. Patients were treated with up to 5 ICT cycles, whose regimen was selected according to histotype, followed either by curative chemo-RT for pts with ≥80% reduction of initial tumour diameter or surgery and adjuvant (chemo)RT. Photon and/or proton/carbon ion-based RT was employed according to the disease site and stage. Primary end-point was 5-year progression-free survival (PFS), secondary end-points were overall survival (OS), ICT objective response rate (ORR) per RECIST 1.1 and safety. RESULTS: Thirty-five patients were evaluable for primary end-point. Fourteen patients (40%) were treated with definitive (CT)RT and 20 (57%) underwent surgery. Five-year PFS was 38% (95% confidence interval [CI], 21-69), with a median PFS of 26 months. Five-year OS was 46% (95% CI, 28-75), with a median OS of 36 months. Three-year PFS-OS for pts achieving PR/CR versus stable disease (SD)/PD to ICT were 49.8-57% versus 43.2-53%, respectively. Three-year PFS for patients achieving major volumetric partial response (≥80% reduction of initial tumour volume, major partial volumetric response [mPRv]) versus non-mPRv were 82% versus 28% and 3-year OS were 92% versus 36% (p value 0.010 and 0.029, respectively). The ORR to ICT was 54% and 60% across all histotypes and in the sinonasal undifferentiated carcinoma (SNUC) subpopulation, respectively, with 6/15 SNUCs (40%) achieving mPRv. CONCLUSION: Treatment of advanced sinonasal cancer with histology-driven ICT followed by (CT)RT in responsive patients was feasible. Overall, these findings suggest a possible role of ICT as the primary approach in newly diagnosed, resectable sinonasal tumours-especially SNUC-to select patients with favourable prognosis. Histology heterogeneity limits generalisation of trial results.

OBJECTIVES: The improvements in survival with expansion of the survivors' population, along with evolution of endoscopically-based treatment modalities, have contributed to emphasize the clinical relevance of recurrences in sinonasal cancers. However, at present, literature is scant regarding the pattern of recurrences and the therapeutic strategies available to manage long survivors who experienced single or multiple failures. The aim of the present study was to analyze sinonasal cancers recurrences to provide data regarding rates and patterns of relapse, predictors of failure and prognostic impact of the recurrence. MATERIALS AND METHODS: All patients receiving multimodal treatments including endoscopic surgery between 1995 and 2021 in three European referral centers were included. Statistical analysis of survival was performed through univariable, multivariable and unidirectional multistate models. Survival after recurrence analysis was implemented for patients experiencing at least one recurrence. RESULTS: The 5- and 10-year recurrence free survival rates were 34.1% and 38.4% for the whole population. With a mean follow-up time of 60 months, a global recurrence rate of 32.9% was observed. The 5- and 10-year survival after recurrence rates were 27.2% and 21.7%, respectively. Incidence and rates of recurrences were significantly associated with histology subtypes. CONCLUSION: This study provides valuable oncologic outcomes regarding a large homogenous cohort of patients affected by sinonasal malignances treated within a multimodal framework, emphasizing the strong correlation of histologic type with prognosis, as well as with pattern of recurrences.

BACKGROUND: Over the last 2 decades, transnasal endoscopic surgery (TES) has become the most frequently employed surgical technique to treat sinonasal malignancies. The rarity and heterogeneity of sinonasal cancers have hampered large non-population-based analyses. METHODOLOGY: All patients receiving TES-including treatment between 1995 and 2021 in 5 referral hospitals were included. A prognostic study was performed, and multivariable models were transformed into nomograms. Training and validation sets were based on results from 3 European and 2 non-European centres, respectively. RESULTS: The training and validation set included 940 and 420 patients, respectively. The mean age at surgery, primary-versus-recurrent presentation, histology distribution, type of surgery, T category and type of adjuvant treatment were differently distributed in the training and validation set. In the training set, 5-year overall survival and recurrence-free survival with a 95%-confidence interval were 72.7% (69.5-76.0%) and 66.4% (63.1-69.8%), respectively, significantly varying with histology. At multivariable analyses, age, gender, previous treatment, the extent of resection on the cranial, lateral and posterolateral axes, grade/subtype, T category, nodal status, margin status and adjuvant treatment were all associated with different prognostic outcomes, displaying a heterogeneous significance and effect size according to histology. The internal and external validation of nomograms was satisfactory (optimism-corrected C-index >0.7 and cumulative area under curve >0.7) for all histologies but mucosal melanoma. CONCLUSIONS: Outcomes of TES-based treatment of sinonasal cancers vary substantially with histology. This large, non-population-based study provides benchmark data on the prognosis of sinonasal cancers that are deemed suitable for treatment including TES.

Head and neck cancer (HNC) can have a devastating impact on patient's lives as both disease and treatment may affect the ability to speak, swallow and breathe. These conditions limit the oral intake of food and drugs, reduce social functioning and impact on patient's quality of life. Up to 80% of patients suffering from HNC have pain due to the spread of the primary tumor, because of consequences of surgery, or by developing oral mucositis, dysphagia or neuropathy as toxic side effects of radiotherapy, chemotherapy or both. All healthcare professionals caring for HNC patients should assess palliative and supportive care needs in initial treatment planning and throughout the disease, with awareness when specialist palliative care expertise is needed. This paper focuses on assessment, characterizations and clinical management of pain in advanced HNC patients undergoing surgery, chemotherapy and radiotherapy, also underlining the importance of symptom assessment in HNC survivors and the need of clinical research in this field.

Gemcitabine is a purine analog with known activity in many solid tumors, namely lung, breast, pancreatic, genitourinary and head/neck cancers. Cardiac toxicity is a rare event and only one report previously described atrial fibrillation (AF) as a consequence of gemcitabine infusion. We report two cases of women suffering from lung cancer who were treated with gemcitabine. Both patients were admitted to hospital for paroxysmal AF occurring 12-24 h after the infusion of the drug. In the first case a sinus rhythm was spontaneously repristinated when AF occurred for the first time, while the second episode required an anti-arrhythmic drug to interrupt the dysrhythmia. In the second case, the patient had to be treated with digitalis glycoside to control the ventricular response without attaining a sinus rhythm. We could not recognize any other precipitating factor beyond the infusion of gemcitabine as a cause for the arrhythmia. Both cases were treated with gemcitabine for lung cancer and we observed the appearance of AF less than 24 h after drug administration. We assume that 2',2'-difluorodeoxyuridine, an active metabolite of gemcitabine, could be responsible for the toxic effect. We conclude that AF is an unusual, but potentially dangerous, side-effect of gemcitabine infusion. The arrhythmia should be suspected whenever patients complain of dyspnea and palpitations beginning 12-24 h after treatment. In these cases, the treatment of AF consists of anti-arrhythmic drugs in order to repristinate a sinus rhythm or control the heart rate.
