Efficacy of High-Ozonide Oil in Prevention of Cancer Relapses Mechanisms and Clinical Evidence.

BACKGROUND: Cancer tissue is characterized by low oxygen availability triggering neo angiogenesis and metastatisation. Accordingly, oxidation is a possible strategy for counteracting cancer progression and relapses. Previous studies used ozone gas, administered by invasive methods, both in experimental animals and clinical studies, transiently decreasing cancer growth. This study evaluated the effect of ozonized oils (administered either topically or orally) on cancer, exploring triggered molecular mechanisms. METHODS: In vitro, in lung and glioblastoma cancer cells, ozonized oils having a high ozonide content suppressed cancer cell viability by triggering mitochondrial damage, intracellular calcium release, and apoptosis. In vivo, a total of 115 cancer patients (age 58 ± 14 years; 44 males, 71 females) were treated with ozonized oil as complementary therapy in addition to standard chemo/radio therapeutic regimens for up to 4 years. RESULTS: Cancer diagnoses were brain glioblastoma, pancreas adenocarcinoma, skin epithelioma, lung cancer (small and non-small cell lung cancer), colon adenocarcinoma, breast cancer, prostate adenocarcinoma. Survival rate was significantly improved in cancer patients receiving HOO as integrative therapy as compared with those receiving standard treatment only. CONCLUSIONS: These results indicate that ozonized oils at high ozonide may represent an innovation in complementary cancer therapy worthy of further clinical studies.

Metronomic oral vinorelbine in patients with advanced non-small cell lung cancer progressing after nivolumab immunotherapy: a retrospective analysis.

PURPOSE: The availability of immune checkpoint inhibitors has deeply changed the therapeutic scenario of patients with advanced non-small cell lung cancer (NSCLC). Up until now, chemotherapy still represents the first-line treatment for patients with advanced NSCLC not harbouring genetic mutations or lacking high expression of programmed death ligand even if the addition of immunotherapy to first-line chemotherapy has recently been shown to improve clinical outcome. We carried out a multi-institutional retrospective analysis on third-line chemotherapy with metronomic oral vinorelbine (VNR) in a series of patients with metastatic NSCLC pre-treated with first-line chemotherapy and second-line immunotherapy. PATIENTS AND METHODS: Thirty patients with metastatic NSCLC with progressive disease after first-line chemotherapy and subsequent immunotherapy were treated with metronomic oral VNR continuously at the fixed dose of 30 mg three times per week. RESULTS: A partial response was achieved in 4 patients (13.3%), while 10 patients (33.3%) displayed disease stabilisation for an overall disease control rate of 46.7%. Median progression-free survival was 3.9 months (range 1-13 months) and median OS reached 8.1 months (range 4.0-24.0+ months) with a 12-month survival rate of 22%. CONCLUSION: Oral metronomic VNR appears to be active and safe in patients with metastatic NSCLC in progression after first-line chemotherapy and second-line immunotherapy. The results reported, although from a limited sample, may suggest its use for long-term stabilisation of the disease with good patient compliance.

Sharing real-world experiences to optimize the management of olaparib toxicities: a practical guidance from an Italian expert panel.

Olaparib is the first poly(ADP-ribose) polymerase inhibitor approved as maintenance therapy of recurrent ovarian cancer (OC) patients with a BRCA mutation. To achieve the maximum clinical benefit, adherence to olaparib must be persistent. However, in clinical practice, this is challenged by the frequent suboptimal management of toxicities. In view of the expanding use of olaparib also in Italy, physicians must learn how to adequately and promptly manage drug toxicities not to unnecessarily interrupt or reduce the dose. The experts agreed that nausea,vomiting, anemia, and fatigue are the most frequent events experienced by OC patients on olaparib, and that these toxicities usually develop early during treatment, are mainly of grade 1-2 and transient and can be managed with simple non-pharmacological interventions. By sharing their real-world experiences, the panel prepared, for each toxicity, an algorithm organized by grade and besides the procedures indicated in the local label, included supportive care interventions based also on nutritional and lifestyle modifications and psycho-oncology consultation. Moreover, in view of the tablet entry into the Italian market, the full and reduced dosages of capsules and tablets were compared. This practical guidance is intended to be a tool to support especially less-experienced physicians in the management of these complex patients, with the aim to help preventing the worsening of patients' conditions and the unnecessary interruption/reduction of olaparib dosage, which may jeopardize treatment efficacy.

Eribulin efficacy based on type of metastatic site: a real-life study in heavily pretreated metastatic breast cancer.

AIM: The halichondrin B analog, eribulin, exerts an anticancer effect, as reported by several clinical and real-life studies on metastatic breast cancer patients. Here, we evaluated efficacy and safety of eribulin, focusing on response to treatment per metastasis type. PATIENTS & METHODS: This monocentric, real-life study was conducted on 31 heavily pretreated patients with metastatic breast cancer. RESULTS: The median progression-free survival and overall survival were 2.0 and 5.5 months, respectively. All patients (12.9%) responding to eribulin were treated in fourth-line setting. Considering response per metastasis type, bone lesions (13.6%) responded more frequently than other metastases to eribulin. CONCLUSION: Eribulin exhibited a good overall response rate, with the highest response observed for bone metastases.

Everolimus in combination with octreotide long-acting repeatable in a first-line setting for patients with neuroendocrine tumors: an ITMO group study.

BACKGROUND: Preclinical and clinical studies suggest synergistic activity between somatostatin analogues and mammalian target of rapamycin inhibitors. The activity and safety of everolimus was assessed in combination with octreotide long-acting repeatable (LAR) in patients with neuroendocrine tumors (NETs) of gastroenteropancreatic and lung origin. METHODS: This was a phase 2, multicenter trial using a Simon's 2-stage minimax design. Treatment-naive patients with advanced well-differentiated NETs of gastroenteropancreatic tract and lung origin received everolimus 10 mg daily, in combination with octreotide LAR 30 mg every 28 days. The primary endpoint was objective response rate (ORR). RESULTS: A total of 50 patients (median age, 60.5 years) were enrolled. Primary tumor sites were: pancreas (14 patients), lung (11 patients), ileum (9 patients), jejunum and duodenum (2 patients), and unknown (14 patients). Thirteen patients (26%) had carcinoid syndrome. Treatment-related adverse events (AEs) were mostly grade 1 or 2; the only grade 4 AE was mucositis in 1 patient, whereas grade 3 AEs included skin rash in 1 case (2%), stomatitis in 4 cases (8%), and diarrhea in 11 cases (22%). The ORR was 18%; 2% of patients had a complete response (CR), 16% a partial response (PR) and 74% achieved stable disease (SD). All CRs and all PRs as well as 92% of SDs had a duration ≥ 6 months. The clinical benefit (CR+PR+SD) was 92%. At a median follow-up of 277 days, median time to progression and overall survival were not reached. CONCLUSIONS: The everolimus-octreotide LAR combination was active and well tolerated in these previously treated patients with advanced NETs, suggesting a possible role as first-line treatment in patients with NET.
