OBJECTIVE Microsurgical resection of arteriovenous malformations (AVMs) can be aided by staged treatment consisting of stereotactic radiosurgery followed by resection in a delayed fashion. This approach is particularly useful for high Spetzler-Martin (SM) grade lesions because radiosurgery can reduce flow through the AVM, downgrade the SM rating, and induce histopathological changes that additively render the AVM more manageable for resection. The authors present their 28-year experience in managing AVMs with adjunctive radiosurgery followed by resection. METHODS The authors retrospectively reviewed records of patients treated for cerebral AVMs at their institution between January 1990 and August 2019. All patients who underwent stereotactic radiosurgery (with or without embolization), followed by resection, were included in the study. Of 1245 patients, 95 met the eligibility criteria. Univariate and multivariate regression analyses were performed to assess relationships between key variables and clinical outcomes. RESULTS The majority of lesions treated (53.9%) were high grade (SM grade IV–V), 31.5% were intermediate (SM grade III), and 16.6% were low grade (SM grade I–II). Hemorrhage was the initial presenting sign in half of all patients (49.5%). Complete resection was achieved among 84% of patients, whereas 16% had partial resection, the majority of whom received additional radiosurgery. Modified Rankin Scale (mRS) scores of 0–2 were achieved in 79.8% of patients, and 20.2% had poor (mRS scores 3–6) outcomes. Improved (44.8%) or stable (19%) mRS scores were observed among 63.8% of patients, whereas 36.2% had a decline in mRS scores. This includes 22 patients (23.4%) with AVM hemorrhage and 6 deaths (6.7%) outside the perioperative period but prior to AVM obliteration. CONCLUSIONS Stereotactic radiosurgery is a useful adjunct in the presurgical management of cerebral AVMs. Multimodal therapy allowed for high rates of AVM obliteration and acceptable morbidity rates, despite the predominance of high-grade lesions in this series of patients.

BACKGROUND: Neuroendocrine neoplasm (NEN) is an epithelial cell neoplasm that can give a histopathological appearance resembling high-grade colorectal adenocarcinoma. Immunohistochemical assays with specific neuroendocrine markers of chromogranin A and synaptophysin are required to establish a definite diagnosis of NEN. AIM: This study aimed to determine whether there was an expression of chromogranin A, synaptophysin and Ki67 which indicated the presence of neuroendocrine neoplasms in samples that have been diagnosed as high-grade colorectal adenocarcinoma. MATERIALS AND METHODS: A study of the expression of chromogranin A, synaptophysin and Ki67 in paraffin blocks was carried out as a result of biopsy and tissue surgery of 70 samples of colorectal tumor specimens diagnosed with colorectal adenocarcinoma. Descriptive analyses were used to assess the study results of the amount of chromogranin A, synaptophysin, and sample characteristics. RESULTS: We discovered that eight (8) samples (11.4%) were NEN from 70 previously diagnosed samples as high-grade colorectal adenocarcinoma using immunohistochemical assay with neuroendocrine markers, namely chromogranin A and synaptophysin. CONCLUSION: The final diagnosis obtained from 8 samples diagnosed as NEN were Neuroendocrine tumor (NET) G1, G2, and G3, respectively 1.4% and LCNEC 7.1% based on the specific neuroendocrine markers of chromogranin A, synaptophysin and Ki67.

AbstractThe clinical impact of ET-743 (trabectedin; Yondelis) in women with leiomyosarcoma and undifferentiated uterine sarcoma in patients previously treated with chemotherapy is investigated. Current data show a clinical benefit in 2/5 patients, of which 1 had a partial remission during 9 months. Pooling the treatment outcomes with literature data, a response in 5 (38%) of 13 patients and a clinical benefit in 7 (54%) of 13 patients for all high-grade uterine sarcomas is calculated. When only uterine leiomyosarcomas are concerned, response rate is 5 (45%) of 11 patients with a clinical benefit in 7 (64%) of 11 patients. These results on the use of ET-743 in uterine sarcoma patients support the conductance of larger trials.

Aim and background High-grade gastrointestinal neuroendocrine neoplasms, ie, poorly differentiated neuroendocrine carcinomas, with no effective therapeutic approaches, have a high ability to metastasize. Methods A review of the hospital information system was performed. Patients with histologically proven gastrointestinal neuroendocrine carcinoma who were treated with irinotecan combined with 5-fluorouracil and leucovorin in a first-line setting were eligible for analysis. We extracted information on age, sex, disease stage, laboratory findings, radiological findings, pathological findings, chemotherapy, effectiveness and adverse events of therapy, and outcomes. Results Eleven patients were included in the study. Partial response was observed in 7 patients. Median progression-free survival and overall survival were 6.5 (95% CI, 5.1–7.9) and 13.0 (95% CI, 9.8–16.2) months, respectively. No treatment-related deaths occurred. Conclusions The results demonstrated that irinotecan combined with 5-fluorouracil and leucovorin is an active regimen with acceptable toxicity for patients with metastatic high-grade gastointestinal neuroendocrine carcinoma that merits further investigation in prospective trials.
