RESUMO
BACKGROUND: To reach a consensus on recommendations for the management of high-risk and post-operative non-metastatic prostate cancer by a group of Radiation Oncologists in Catalonia dedicated to prostate cancer. METHODS: A modified Delphi approach was employed to reach consensus on controversial topics in Radiation Oncology on high-risk non-metastatic (eight questions) and post-operative (eight questions) prostate cancer. An agreement of at least 75% was considered as consensus. The survey was electronically sent 6 weeks before an expert meeting where topics were reviewed and discussed. A second-round survey for the controversial questions only was sent and answered by participants after the meeting. RESULTS: After the first round of the survey, 19 experienced Radiation Oncologists attended the meeting and 74% fulfilled the second-round online questionnaire. An agreement of 9 of the 16 questions was accounted for the first round. After the meeting, an additional agreement was reached in 3 questions leading to a final consensus on 12 of the 16 questions. There are still controversial topics like the use of PET for staging of high-risk and post-operative non-metastatic prostate cancer and the optimal dose to the prostate bed in the salvage setting. CONCLUSION: This consensus contributes to establish recommendations and a framework to help in prostate cancer radiation therapy and pharmacological management in daily clinical practice of high-risk and post-operative non-metastatic prostate cancer.

BACKGROUND: Oral cavity cancer (OCC) and oropharyngeal cancer (OPC) are two common malignancies whose mortality is worryingly increasing worldwide. However, few studies have estimated the mortality trends for these cancers in the coming years. This study analysed the mortality rates for OCC and OPC observed between 1980 and 2019 to generate a predictive model for the next 25 years in Spain. METHODS: Mid-year population data and death certificates for the period 1980-2019 were obtained from the Spanish National Institute of Statistics. The Nordpred program (Norwegian Cancer Registry, Oslo, Norway) was used to calculate adjusted mortality rates as well as estimated mortality projections with an age-period-cohort model for the period 2020-2044. RESULTS: The specific mortality rate per 100,000 inhabitants for OCC decreased from 2.36 (1980-1984) to 2.17 (2015-2019) and is expected to decline to 1.68 (2040-2044), particularly in males. For OPC, mortality rates rose from 0.67 (1980-1984) to 1.23 (2015-2019) and are projected to drop to 0.71 (2040-2044). In the group of females > 65 years predictions showed rising mortality rates for both OCC and OPC. The predictive model projects more deaths in females than in males for OCC in the period 2040-2044, while deaths for OPC will decrease in males and gradually increase in females. CONCLUSIONS: Although OCC mortality rates have been found to decrease in males in the last observed decades, there is still room to improve them in females > 65 years in the future by promoting campaigns against smoking and alcohol consumption. OPC mortality will become a growing health problem. Vaccination campaigns for the prevention of human papillomavirus-associated cancers may have a long-term impact on the mortality of these cancers, which should be evaluated in upcoming studies. CLINICAL RELEVANCE: Our findings highlighted the importance of closely monitoring OCC and OPC mortality rates in the coming years by age group and sex, and the need to continue preventive measures against the main known risk factors, such as tobacco, alcohol, and human papillomavirus infection.

PURPOSE: Molecular subtype classifications in glioblastoma may detect therapy sensitivities. IHC would potentially allow the identification of molecular subtypes in routine clinical practice. EXPERIMENTAL DESIGN: Formalin-fixed, paraffin-embedded tumor samples of 124 uniformly treated, newly diagnosed patients with glioblastoma were submitted to RNA sequencing, IHC, and immune-phenotyping to identify differences in molecular subtypes associated with treatment sensitivities. RESULTS: We detected high molecular and IHC overlapping of the The Cancer Genome Atlas (TCGA) mesenchymal subtype with instrinsic glioma subtypes (IGS) cluster 23 and of the TCGA classical subtype with IGS cluster 18. IHC patterns, gene fusion profiles, and immune-phenotypes varied across subtypes. IHC revealed that the TCGA classical subtype was identified by high expression of EGFR and low expression of PTEN, while the mesenchymal subtype was identified by low expression of SOX2 and high expression of two antibodies, SHC1 and TCIRG1, selected on the basis of RNA differential transcriptomic expression. The proneural subtype was identified by frequent positive IDH1 expression and high Olig2 and Ki67 expression. Immune-phenotyping showed that mesenchymal and IGS 23 tumors exhibited a higher positive effector cell score, a higher negative suppressor cell score, and lower levels of immune checkpoint molecules. The cell-type deconvolution analysis revealed that these tumors are highly enriched in M2 macrophages, resting memory CD4+ T cells, and activated dendritic cells, indicating that they may be ideal candidates for immunotherapy, especially with anti-M2 and/or dendritic cell vaccination. CONCLUSIONS: There is a subset of tumors, frequently classified as mesenchymal or IGS cluster 23, that may be identified with IHC and could well be optimal candidates for immunotherapy.

We explored predictive factors of pseudoprogression (PsP) and its impact on prognosis in a retrospective series of uniformly treated glioblastoma patients. Patients were classified as having PsP, early progression (eP) or neither (nP). We examined potential associations with clinical, molecular, and basal imaging characteristics and compared overall survival (OS), progression-free survival (PFS), post-progression survival (PPS) as well as the relationship between PFS and PPS in the three groups. Of the 256 patients studied, 56 (21.9%) were classified as PsP, 70 (27.3%) as eP, and 130 (50.8%) as nP. Only MGMT methylation status was associated to PsP. MGMT methylated patients had a 3.5-fold greater possibility of having PsP than eP (OR: 3.48; 95% CI: 1.606-7.564; P = 0.002). OS was longer for PsP than eP patients (18.9 vs. 12.3 months; P = 0.0001) but was similar for PsP and nP patients (P = 0.91). OS was shorter-though not significantly so-for PsP than nP patients (OS: 19.5 vs. 27.9 months; P = 0.63) in methylated patients. PPS was similar for patients having PsP, eP or nP (PPS: 7.2 vs. 5.4 vs. 6.7; P = 0.43). Neurological deterioration occurred in 64.3% of cases at the time they were classified as PsP and in 72.8% of cases of eP (P = 0.14). PsP confounds the evaluation of disease and does not confer a survival advantage in glioblastoma.

Long-term toxic effects of prophylactic cranial irradiation (PCI) on cognition in small cell lung cancer (SCLC) patients have not yet been well-established. The aim of our study was to examine the cognitive toxic effects together with brain structural changes in a group of long-term SCLC survivors treated with PCI. Eleven SCLC patients, who underwent PCI ≥ 2 years before, were compared with an age and education matched healthy control group. Both groups were evaluated using a neuropsychological battery and multimodal structural magnetic resonance imaging. Voxel-based morphometry and Tract-based Spatial Statistics were used to study gray matter density (GMD) and white matter (WM) microstructural changes. Cognitive deterioration was correlated with GMD and Fractional Anisotropy (FA). Finally, we carried out a single-subject analysis in order to evaluate individual structural brain changes. Nearly half of the SCLC met criteria for cognitive impairment, all exhibiting a global worsening of cognitive functioning. Patients showed significant decreases of GMD in basal ganglia bilaterally (putamen and caudate), bilateral thalamus and right insula, together with WM microstructural changes of the entire corpus callosum. Cognitive deterioration scores correlated positively with mean FA values in the corpus callosum. Single-subject analysis revealed that GMD and WM changes were consistently observed in nearly all patients. This study showed neuropsychological deficits together with brain-specific structural differences in long-term SCLC survivors. Our results suggest that PCI therapy, possibly together with platinum-based chemotherapy, was associated to permanent long-term cognitive and structural brain effects in a SCLC population.

Pulmonary blastomas are rare malignant tumors, comprising only 0.25-0.5% of all malignant lung neoplasms. The prognosis of pulmonary blastoma is very poor, with an overall five-year survival of 16%. No standard treatment has been defined for unresectable disease. We present the case of a 25-year-old woman with unresectable locally advanced classic biphasic pulmonary blastoma (CBPB) successfully treated with neodjuvant chemoradiotherapy based on two chemotherapy induction cycles of cisplatin plus etoposide, followed by concurrent weekly cisplatin to 50.4 Gy radiotherapy treatment. The patient had a significant reduction in tumor size, allowing for complete resection by pneumonectomy. Molecular study for epidermal growth factor receptor (EGFR) mutations, anaplastic lymphoma kinase (ALK), proto-oncogene receptor tyrosine kinase (ROS1) and rearranged during transfection (RET) rearrangements, and programmed death ligand 1 (PD-L1) expression was performed in the pre-treatment tumor sample. Our patient presented a high expression (>90% of tumor cells) of PD-L1. To our knowledge, this is the first report of PD-L1 expression in CBPB. This could lead to new treatment options based on new immunotherapy agents blocking the PD-1/PD-L1 pathway for this rare disease with poor prognosis.

Osteopetrosis is a heterogeneous disorder characterized by abnormal bone remodeling and increased bone density primarily due to defective osteoclast resorption. The diagnosis is based on a history of numerous fractures and radiological findings indicative of osteosclerosis, usually sufficient for a definitive diagnosis. We present a quite rare case of osteopetrosis complicated by recurrent episodes of maxillomandibular osteomyelitis associated with cutaneous fistulization and purulent nasal discharge. We used intravenous antibiotic therapy and necrotic bone debridement that prevented the appearance of acute infections over a 3-year follow-up, but the complete healing of the case was not achieved.

Ameloblastoma is a locally invasive benign odontogenic tumor with a high rate of recurrence in the long term. The authors conducted a retrospective study of patients with mandibular ameloblastoma in order to evaluate recurrent ameloblastoma management. The study included data from 31 patients over a period of 10 years. Data collected included age, gender, tumor location, histological findings, initial treatment, number of recurrences and year of onset, type of treatment of recurrence, reconstruction and follow-up. Recurrences were detected in nine patients (29%). Tumor recurrences appeared at 32 months on average following the initial surgical procedure. Recurrences were associated mainly to inadequate initial therapeutic approach and were treated by bone resection with a safety margin of at least 1 cm beyond the radiographically visible margins. Immediate reconstruction of bone defects was performed with grafts or free flaps.

PURPOSE: Although concurrent chemotherapy and radiation is the standard approach for good risk unresectable stage III non-small cell lung cancer (NSCLC) patients, there is no optimal concurrent chemotherapy regimen. Administration of chemotherapy at full dose with maximal activity against local and micrometastatic disease is highly desirable. This study tested the feasibility of 3 cycles of full dose cisplatin and pemetrexed concurrent with definitive thoracic radiotherapy followed by consolidation pemetrexed, without the dose-limiting toxicity (DLT) exceeding 33% of the patients. METHODS: Patients with unresectable stage III NSCLC, good performance status and no serious comorbidity were eligible. Patients received thoracic radiation to a dose of 66 Gy concurrently with three 21-day cycles of pemetrexed 500 mg/m(2), and cisplatin at escalating doses from 60 to 75 mg/m(2). Consolidation chemotherapy of pemetrexed 500 mg/m(2) was provided for 3 more 21-day cycles. Cisplatin doses were escalated as far as no more than 1/3 of the patients in a level developing dose limiting toxicities (DLT). RESULTS: Fifteen eligible patients were enrolled: nine in the first dose level and 3 in the second and third dose levels respectively. Two out of 9 patients in the first dose level experienced DLT (grade 3 esophagitis resulting in delay in treatment administration). The major serious acute toxicities were esophagitis (40%) and febrile neutropenia (20%). With a median follow up time of 22 months, median time to progression and overall survival has not been reached. The rate of survival at 24 months was 57.5% (95% CI: 27.5-87.4%) of the patients. CONCLUSIONS: Three systemic dose levels of pemetrexed and cisplatin could be administered concurrently with radiotherapy. The rate of survival at 24 months was encouraging.

Odontogenic fibromyxomas are benign odontogenic tumors of mesenchymal origin of rare presentation in the oral cavity, which exhibit locally aggressive behavior and are prone to local recurrence. The controversy has mainly been on therapeutic management with recommendations varying, depending on the clinical cases, from simple curettage of lesion to segmental bone resection. We present a case report describing the reconstruction of an osseous defect in the maxilla and the restoration with dental implants in a 32 year old female patient after radical surgical excision due to an odontogenic fibromyxoma with locally aggressive behavior. The primary reconstruction of maxillary discontinuity defect was carried out by an immediate non-vascularized cortico-cancellous iliac crest graft. Using a computer-guided system for the implant treatment-planning, three dental implants were secondary placed in the bone graft by means of flapless implant surgery. The patient was subsequently restored with an implant-supported fixed prosthesis that has remained in continuous function for a period of three years. The surgical, reconstructive and restorative treatment sequence and techniques are discussed.
