The standard of care (SOC) for high-grade gliomas (HGG) is maximally safe surgical resection, followed by concurrent radiation therapy (RT) and temozolomide (TMZ) for 6 weeks, then adjuvant TMZ for 6 months. Before this SOC was established, glioblastoma (GBM) patients typically lived for less than one year after diagnosis, and no adjuvant chemotherapy had demonstrated significant survival benefits compared with radiation alone. In 2005, the Stupp et al. randomized controlled trial (RCT) on newly diagnosed GBM patients concluded that RT plus TMZ compared to RT alone significantly improved overall survival (OS) (14.6 vs. 12.1 months) and progression-free survival (PFS) at 6 months (PFS6) (53.9% vs. 36.4%). Outside of TMZ, there are four drugs and one device FDA-approved for the treatment of HGGs: lomustine, intravenous carmustine, carmustine wafer implants, bevacizumab (BVZ), and tumor treatment fields (TTFields). These treatments are now mainly used to treat recurrent HGGs and symptoms. TTFields is the only treatment that has been shown to improve OS (20.5 vs. 15.6 months) and PFS6 (56% vs. 37%) in comparison to the current SOC. TTFields is the newest addition to this list of FDA-approved treatments, but has not been universally accepted yet as part of SOC.

Infiltrating Lymphocytes

Objectives: The aim of this study was to assess the number of tumour-infiltrating lymphocytes (TILs) and the expression of Programmed Cell Death 1 Ligand 1 (PD-L1) in Acinic Cell Carcinoma (AciCC) of the salivary glands, to enable a correlation with clinico-pathological features and to analyse their prognostic impact. Methods: This single centre retrospective study represents a cohort of 36 primary AciCCs with long-term clinical follow-up. Immunohistochemically defined immune cell subtypes, i.e., those expressing T-cell markers (CD3, CD4 and CD8) or a B-cell marker (CD20) were characterized on tumour tissue sections. The number of TILs was quantitatively evaluated using software for digital bioimage analysis (QuPath). PD-L1 expression on the tumour cells and on immune cells was assessed immunohistochemically employing established scoring criteria: tumour proportion score (TPS), Ventana immune cell score (IC-Score) and combined positive score (CPS). Results: Higher numbers of tumour-infiltrating T- and B- lymphocytes were significantly associated with high-grade transformation. Furthermore, higher counts of T-lymphocytes correlated with node-positive disease. There was a significant correlation between higher levels of PD-L1 expression and lymph node metastases as well as the occurrence of high-grade transformation. Moreover, PD-L1 CPS was associated with poor prognosis regarding metastasis-free survival (p = 0.049). Conclusions: The current study is the first to demonstrate an association between PD-L1 expression and lymph node metastases as well as grading in AciCCs. In conclusion, increased immune cell infiltration of T and B cells as well as higher levels of PD-L1 expression in AciCC in association with high-grade transformation, lymph node metastasis and unfavourable prognosis suggests a relevant interaction between tumour cells and immune cell infiltrates in a subset of AciCCs, and might represent a rationale for immune checkpoint inhibition.

PURPOSE: To investigate whether the addition of cisplatin (CDDP) to hyperfractionation (Hfx) radiation therapy (RT) offers an advantage over the same Hfx RT given alone in locally advanced (stages III and IV) squamous cell carcinoma of the head and neck. PATIENTS AND METHODS: One hundred thirty patients were randomized to receive either Hfx RT alone to a tumor dose of 77 Gy in 70 fractions in 35 treatment days over 7 weeks (group I, n = 65) or the same Hfx RT and concurrent low-dose (6 mg/m2) daily CDDP (group II, n = 65). RESULTS: Hfx RT/chemotherapy offered significantly higher survival rates than Hfx RT alone (68% v 49% at 2 years and 46% v 25% at 5 years; P = .0075). It also offered higher progression-free survival (46% v 25% at 5 years; P = .0068), higher locoregional progression-free survival (LRPFS) (50% v 36% at 5 years; P = .041), and higher distant metastasis-free survival (DMFS) (86% v 57% at 5 years; P = .0013). However, there was no difference between the two treatment groups in the incidence of either acute or late high-grade RT-induced toxicity. Hematologic high-grade toxicity was more frequent in group II patients. CONCLUSION: As compared with Hfx RT alone, Hfx RT and concurrent low-dose daily CDDP offered a survival advantage, as well as improved LRPFS and DMFS.

Recent evidence implicates cell surface proteins of the tetraspanin superfamily in the process of metastasis whereas the downregulation of KAI-1, a member of the tetraspanin family, is associated with an aggressive clinical phenotype in several types of human cancers. To determine if expression of KAI-1-1 is associated with any known prognostic marker or clinical outcome in high-grade osteosarcoma, we examined 91 nondecalcified archival samples from 47 patients for the expression of KAI-1. Archival, paraffin-embedded, and decalcified pathologic samples were examined by immunohistochemistry and results were correlated to clinical outcomes and known prognostic markers. There were 46 samples from diagnostic biopsies (1 diagnostic sample was not available), 32 tumor resection samples, and 13 metastasis samples. Thirty-three percent (n = 30) of the samples expressed KAI-1 (16 biopsies, 9 resections, and 5 metastasis). KAI-1 expression was not significantly related to known prognostic markers or to either tumor necrosis after neoadjuvant therapy or the incidence of metastasis at diagnosis. KAI-1 expression was not significantly different between paired diagnostic tumor samples and either resection or metastasis tumor samples. Twenty-five patients remain alive at a median follow-up of 95 months. The overall and progression-free survival percentages at 5 years were 62% and 47% for KAI-1-positive patients and 49% and 38% for KAI-1-negative patients, respectively. This difference was not statistically significant. We conclude that KAI-1 is expressed in a proportion of high-grade osteosarcoma but is not of clinical significance and cannot be used to stratify treatment groups for these patients.

Objective and design A clinicopathological score has been proposed by Trouillas et al. to predict the evolution of pituitary adenomas. Aim of our study was to perform an independent external validation of this score and identify other potential predictor of post-surgical outcome. Methods The study sample included 566 patients with pituitary adenomas, specifically 253 FSH/LH-secreting, 147 GH-secreting, 85 PRL-secreting, 72 ACTH-secreting and 9 TSH-secreting tumours with at least 3-year post-surgical follow-up. Results In 437 cases, pituitary adenomas were non-invasive, with low (grade 1a: 378 cases) or high (grade 1b: 59 cases) proliferative activity. In 129 cases, tumours were invasive, with low (grade 2a: 87 cases) or high (grade 2b: 42 cases) proliferative activity. During the follow-up (mean: 5.8 years), 60 patients developed disease recurrence or progression, with a total of 130 patients with pituitary disease at last follow-up. Univariate analysis demonstrated a significantly higher risk of disease persistence and recurrence/progression in patients with PRL-, ACTH- and FSH/LH-secreting tumours as compared to those with somatotroph tumours, and in those with high proliferative activity (grade 1b and 2b) or >1 cm diameter. Multivariate analysis confirmed tumour type and grade to be independent predictors of disease-free-survival. Tumour invasion, Ki-67 and tumour type were the only independent prognostic factors of disease-free survival. Conclusions Our data confirmed the validity of Trouillas’ score, being tumour type and grade independent predictors of disease evolution. Therefore, we recommend to always consider both features, together with tumour histological subtype, in the clinical setting to early identify patients at higher risk of recurrence.

Abstract Background Retroperitoneal (RPS) and intra-abdominal sarcomas (IAS) are associated with poor local and abdominal tumor control. Yet, the benefit of preoperative radio- or chemotherapy alone for these entities currently is unclear. Moreover, as intermediate- and high-grade sarcomas have a tendency for early metastasis, exploration of neoadjuvant strategies is of high importance. This analysis reports the results of our 20-year single-institution experience with preoperative neoadjuvant concurrent chemoradiation.Methods From 2000-2019, 27 patients with intermediate- or high-grade RPS or IAS (12 dedifferentiated liposarcoma, 10 leiomyosarcoma, 5 others) were treated with radiotherapy (median dose: 50.4 Gy; range 45-75 Gy) and two cycles of chemotherapy (doxorubicin 50mg/m² BSA/d3 q28 and ifosfamide 1.5g/m2 BSA/d1-5 q28) in neoadjuvant intention. Chemotherapy consisted of doxorubicin alone in two cases and ifosfamide alone in one case. Fifteen patients (56%) received deep regional hyperthermia additionally.Results The median follow-up time was 53 months (± 56.7 months). 92% of patients received two cycles of chemotherapy as planned and 92% underwent surgery. At 5 and 10 years, abdominal-recurrence-free-survival was 74.6% (± 10.1%) and 66.3% (± 11.9%), distant-metastasis-free-survival was 67.2% (± 9.7%) and 59.7% (± 11.1%), and overall-survival was 60.3% (± 10.5%) and 60.3% (± 10.5%), respectively. CTC grade III and IV toxicities were leukocytopenia (85%), thrombocytopenia (33%) and anemia (11%). There were no treatment-related deaths.Conclusions Neoadjuvant chemoradiotherapy with and without hyperthermia for retroperitoneal and intra-abdominal sarcoma is feasible and provided high local control of intermediate - and high-grade sarcoma.

e17552 Background: In platinum-resistant ovarian cancer treatment, single-agent paclitaxel can be used alone or in combination with bevacizumab. We aimed to assess the efficacy and safety profile of a weekly paclitaxel (WP) scheme in heavily pretreated platinum-resistant high-grade serous ovarian carcinoma. Methods: We retrospectively analyzed 30 adult patients with platinum-resistant high-grade serous ovarian carcinoma treated with WP at our institution between 2015 and 2020. Patients with platinum-resistant ovarian, fallopian tube or primary carcinoma of the peritoneum who had received at least 3 doses of WP (80 mg/m2) alone or in combination with bevacizumab until disease progression or unacceptable toxicity were included in the analysis. Progression-free survival was assessed according to the Response Evaluation Criteria in Solid Tumors version 1.1. Information about toxicity was gathered from medical reports and lab tests. Kaplan-Meier curves and Log-rank test were performed for survival estimates. Results: In our sample, the median age was 68 years (IQR: 60-75) and the median number of previous lines of systemic treatment was 3 (range 1-5). 40% of patients received WP in combination with bevacizumab. The disease control rate was 60.7% (42.9% partial response and 17.8% stable disease). In the overall analysis, the median progression-free survival (mPFS) was 5.0 months (95% CI: 2.0-7.1 months). The presence of ascites significantly shortened the mPFS compared to patients without it (1.1 vs 5.1 months, p < 0.001). Even though the addition of bevacizumab to WP improved the mPFS, the difference was not statistically significant compared to WP alone (7.1 vs 4.06 months, p=0.30). Peripheral neuropathy was the most common adverse event (78% all grades, 18% grade 3). No grade 3 hematologic toxicity was registered. Treatment was discontinued in 6 patients (20%) – 4 due to peripheral neuropathy and two because of toxicoderma. Conclusions: In our sample, WP was an active and safe regimen in heavily pretreated platinum-resistant ovarian carcinoma. WP was well tolerated in elderly patients. The presence of ascites was associated to a shorter PFS in patients treated with WP compared to ascites-free patients.
