Abstract Grade II/III meningiomas have increased rates of recurrence with no approved medical therapies. The historical progression-free survival at 6 months (PFS-6) is 25% with rates >35% declared of interest for drug development. NF2 gene inactivation occurs in about half of meningiomas. Based on our studies showing mTORC1 and mTORC2/SGK1 pathway activation in NF2-deficient meningiomas and the paradoxical activation of the mTORC2/AKT pathway, we hypothesized that mTORC1/mTORC2 inhibitors would be active in meningiomas. We studied the effect of vistusertib in patients with progressive/recurrent grade II/III meningiomas (NCT03071874). Vistusertib was administered orally at 125mg twice daily on two consecutive days each week. MRIs were obtained every 56 days. Tumor size was defined as the largest cross-sectional area. Progression was defined as ≥ 25% increase in the sum of products of all measurable lesions over smallest sum observed. The primary endpoint was PFS-6. Secondary endpoints included toxicity, radiographic response, and correlative studies including immunohistochemistry for mTORC1/2 pathway activation and genetic biomarkers. Twenty-eight patients (13 female, median age 58 years, median KPS 80%) were enrolled. Median tumor size was 4.4cm; 71% were grade II and 50% harbored pathogenic NF2 variants. Four patients discontinued treatment voluntarily and 1 each withdrew for intercurrent illness and non-compliance. PFS-6 is 47% (CI, 26%-65%) and OS-12 is 72% (95%CI, 48%-86%). PFS but not OS was shorter for patients with grade 3 meningiomas; there was no difference in PFS/OS between genetic groups. Adverse events at least possibly related to vistusertib with frequency >10% include nausea, fatigue, hypophosphatemia, diarrhea, anorexia, dry mouth, hypertriglyceridemia, hypertension, vomiting, increased ALT, constipation, and weight loss. Vistusertib treatment was associated with a PFS-6 rate exceeding the target of 35% for recurrent high-grade meningioma. Adverse events were tolerable in this patient population. These data support the continued development of mTORC1/2 inhibitors in this setting.

2024 Background: Grade II/III meningiomas represent about 20% of tumors and have increased rates of recurrence with no approved medical therapies. Historically, the progression-free survival at 6 months (PFS-6) for these tumors is 25%. The Response Assessment in Neuro-Oncology (RANO) group identified a PFS-6 rate of > 35% to be of interest for trials of grade II/III meningioma. Methods : NF2 gene inactivation occurs in the majority of meningiomas and is associated with mTORC1 activation. Human studies of everolimus for neurofibromatosis 2 patients documented growth arrest in only a minority of tumors. Based on our studies showing mTORC2/SGK1 pathway activation in NF2-deficient meningiomas and the known paradoxical activation of the mTORC2/AKT pathway in meningiomas, we hypothesized that dual inhibition of mTORC1/2 would be superior in meningiomas. Treatment of primary meningioma cells with vistusertib led to decreased cell proliferation and showed greater efficacy than rapamycin, regardless of NF2 expression. We studied the effect of vistusertib in patients with progressive or recurrent grade II/III meningiomas (NCT03071874). Vistusertib was administered orally at 125mg twice daily on two consecutive days each week. MRIs were obtained every 2 cycles (1 cycle = 28 days). Tumor size was defined as the largest cross-sectional area. Progression was defined as ≥25% increase in the sum of products of all measurable lesions over smallest sum observed. The primary endpoint was PFS-6. Secondary endpoints included toxicity, radiographic response, and correlative studies including immunohistochemistry for mTORC1/2 pathway activation and genetic biomarkers. Results: Twenty-eight patients (13 female), with a median age of 58 years (range, 32 to 77 years), were enrolled in this multicenter study. The median Karnofsky performance status was 80. Twenty-five patients have been followed to six months or to tumor progression. The median duration of treatment was 6.5 month (range, 1-18 months). Four patients chose to discontinue treatment, 1 withdrew to intercurrent illness, and 1 was withdrawn due to non-compliance. PFS-6 is 51.5% (CI, 29.3% - 70.0%). Adverse events at least possibly related to vistusertib with frequency > 10% include nausea (54%); fatigue (36%); hypophosphatemia (29%); diarrhea, anorexia, dry mouth, and hypertriglyceridemia (all 14%); hypertension, vomiting, increased ALT, constipation, and weight loss (all 11%). Conclusions: Vistusertib treatment was associated with a PFS-6 rate that exceeds the RANO target of 35% for recurrent high-grade meningioma. The follow-up data continue to mature. Adverse events were tolerable in this patient population. Correlative studies to identify biological factors that correlate with response are under way. These data support the initiation of larger randomized studies of vistusertib in this setting. Clinical trial information: NCT03071874.

2007 Background: EORTC-1320-BTG investigated the activity, safety and quality of life of therapy with the tetrahydroisoquinoline alkaloid trabectedin (Yondelis) in patients with recurrent higher-grade meningiomas. Trabectedin was originally derived from the Caribbean sea squirt, Ecteinascidia turbinata, and currently is manufactured by total synthesis. Methods: Adult patients with histological diagnosis of WHO grade II or III meningioma and radiologically documented progression after maximal feasible surgery and radiotherapy were randomly assigned in a 2:1 ratio to receive intravenous trabectedin (1.5 mg/m2every three weeks) or local standard of care (LOC). The primary endpoint was progression-free survival (PFS). Results: Within 22.1 months, we randomized a total of 90 patients (n=29 in LOC arm, n=61 in trabectedin arm) in 35 institutions and nine countries. In the LOC arm, the following treatments were administered: hydroxyurea (n=11), bevacizumab (n=9), none (n=4), chemotherapy (n=3), somatostatin analogue (n=1), combined chemotherapy and somatostatin analogue (n=1). With 71 PFS events, median PFS was 4.17 months in the LOC and 2.43 months in the trabectedin arm (hazard ratio [HR] for progression, 1.42; 80% CI, 1.00-2.03; p=0.204) with a PFS-6 rate of 29.1% (95% CI, 11.9%-48.8%) in the LOC and 21.1% (95% CI, 11.3%-32.9%) in the trabectedin arm. Median OS was 10.61 months in the LOC and 11.37 months in the trabectedin arm (HR for death, 0.98; 95% CI, 0.54-1.76; p=0.94).Grade 3 to 5 adverse events occurred in 44.4% (18.5% related, 4 serious adverse events, 0 lethal events) of the patients in the LOC and 59% (32.8% related, 57 serious adverse events and 2 toxic deaths) of patient in the trabectedin arm. Conclusions: In this first prospective randomized trial performed in recurrent grade II or III meningioma, trabectedin did not improve PFS and OS and was associated with significantly higher toxicity as compared to LOC treatment. The data collected in this study may serve as benchmark for future clinical trials in this setting. Clinical trial information: NCT02234050.

6512 Background: Lenvatinib is an approved therapy for patients with RAIR DTC. While the overall response rate (ORR) is high, few patients achieve a complete response (CR) and most patients eventually have progressive disease (PD). Combination lenvatinib and pembrolizumab is being explored in many different cancers, and this combination has been approved for advanced endometrial carcinoma. Methods: Patients with RAIR DTC with Response Evaluation Criteria in Solid Tumor (RECIST v1.1) measurable PD (<14 months (mo) prior to registration) were enrolled in this single-arm multicenter phase II study. Patients were excluded if they had received previous VEGFR-directed multikinase therapy. The lenvatinib starting dose was 20 mg/day orally and pembrolizumab was 200mg IV every 3 weeks. The primary endpoint was CR. ORR, progression-free survival (PFS) and safety graded by Common Terminology Criteria for Adverse Events v4.0 were secondary endpoints. Results: Thirty patients were enrolled. The median age was 62.5 years, and 53% of the patients were women. Seventy percent of patients had grade 3 adverse events (AEs) and 10 percent had grade 4 AEs. There were no treatment-related deaths. The most common > grade 3 AEs were hypertension (47%), weight loss (13%), maculopapular rash (13%), leukopenia (7%), diarrhea (7%) and oral mucositis (7%). Twenty-one patients (70%) required lenvatinib dose reduction. Of 29 evaluable patients, 18 (62%) had a partial response (PR) and 10 (35%) had stable disease (SD). The clinical benefit rate (ORR +SD) was 97%. Median time to tumor nadir was 7.4 mo (1.6-17.8 mo). Median PFS was not yet reached. The PFS at 12 months was 74%. Median time on therapy was 9.9 mo (3.2-18.9 mo). Fourteen patients are continuing therapy (7.6-18.9 mo). Six of these patients (43%) have not yet reached tumor size nadir. Three patients (10%) had > 80% target tumor shrinkage. Conclusions: Lenvatinib plus pembrolizumab is reasonably tolerated in patients with RAIR DTC. To date, there have been no documented complete responses. Combination lenvatinib plus pembrolizumab therapy has a high ORR in patients with RAIR DTC. Continuation of this study will help determine the depth and length of the responses. Clinical trial information: NCT02973997 .

e17509 Background: Anlotinib is a novel small molecule antiangiogenic drug, which can inhibit multiple tyrosine kinase receptor activity. Its antitumor activity has been proved in various cancers, including gynecological tumors. This retrospective study explored the efficacy and safety of anlotinib monotherapy or anlotinib combined chemotherapy in cervical cancer patients who have disease progressed or metastasis after chemoradiotherapy. Methods: 28 patients with cervical cancer admitted to the Second Affiliated Hospital of Zhengzhou University were enrolled. These patients who had received radiotherapy and at least one line chemotherapy had tumor progression or metastasis. 13 patients received anlotinib monotherapy (12mg/d from day 1 to day 14 in a 21-day cycle) and 15 patients received chemotherapy combined with the anlotinib. Treatment was continued until disease progression or death or intolerable adverse events. The primary endpoint was the objective response rate (ORR), and the secondary endpoints were disease control rate (DCR), progression-free survival (PFS) and safety. Results: As of Dec 31 2020, no one was lost follow up. 2 patients were still under treatment, and 26 patients were evaluable. 1 CR, 6 PR, 13 SD, 6 PD, yielding the ORR of 26.92%, and the DCR of 76.92%. The median PFS for receiving anlotinib monotherapy was 4.57 (95% CI, 3.85-5.29) months, and 8.47 (95% CI, 5.09-11.85) months for combination group. The most common adverse events (AEs)were grade 1, including hypertension (46.43%), anemia (42.85%) and fatigue (39.29%). Grade 3 AEs were hypertension(10.71%) and anemia(7.14%). No higher grade AEs occurred. Conclusions: Anlotinib is safe and effective for patients with advanced cervical cancer after chemoradiotherapy, and it is well tolerated.

e16054 Background: Patients with a detectable PSA after radical prostatectomy (RRP) have persistent disease and inevitably succumb to disease as progression ensues. Radiation has been used in the salvage setting, but has only been found to cure less than half of these patients. SWOG 8794 has recently reported a significant increase in metastasis free survival in 15 years with adjuvant radiation for patients with high risk findings after RRP. It is of particular interest if adjuvant chemoradiation (CRT) can improve the rate of reaching a PSA nadir of zero after RRP in men with persistent or rising PSA. This ongoing IRB approved trial has thus far evaluated the tolerability of CRT utilizing the radiosensitizing agent Docetaxel (DX) for 7 weeks after RRP followed by adjuvant full dose DX (75mg/m2). Methods: Patients: Chemotherapy/hormone naïve, status post RRP, post-op PSA > 0.2 ng/mL on two separate occasions, ECOG ≤ 2; treated with taxane-based chemotherapy (DX 20mg/m2 weekly) concurrent with standard dose radiation for 7 weeks, and post-radiation chemotherapy DX (75mg/ m2) given every 21 days for 4 cycles with premedication intravenous dexamethasone. Primary endpoint: Rate of PSA decline; Number of subjects reaching PSA nadir of zero. Secondary endpoints: Progression Free Survival (PFS) based on PSA progression, toxicity graded via Common Terminology Criteria for Adverse Events Version 3.0 (CTCAE), and overall survival (OS). Results: From 5/07 to 12/08, 16 pts with detectable PSA after RRP were treated; Median age 65 [48–74]; 16/16 completed CRT; 11/16 completed CRT and adjuvant DX; 3/16 dropped out due to adverse events after CRT; Toxicity: 19% (3/16) patients experienced Grade 3 toxicity during CRT and adjuvant DX; 29% (4/14) patients had Grade 3 toxicity during adjuvant DX; no Grade 4 toxicities. See Table . Conclusions: DX in combination with standard radiation appears to be well tolerated in patients with persistent PSA after RRP.

FOLFIRINOX (FX) and gemcitabine (GEM) plus nab-paclitaxel (GnP) have been reported as effective regimens for unresectable advanced pancreatic cancer (APC). FX may be more effective but is also associated with more adverse events (AEs). Therefore, first-line treatment with FX followed by second-line GnP may be appropriate. Aims: To assess the safety and efficacy of second-line GnP for patients with APC after first-line FX failure. Methods: This study was a multicenter prospective phase II study evaluating second-line GnP in patients with APC after failed first-line FX. The primary endpoint was response rate (RR), and the secondary endpoints were overall survival (OS), progression free survival (PFS), and the frequency and degree of adverse events (AEs). Results: Thirty patients (14 male; median age, 64 years) were enrolled. The RR was 13.3%, with a median follow-up time of 9.3 months. The median OS and PFS were 7.6 and 3.8 months, respectively. From the beginning of first-line treatment, the median OS and PFS were 14.2 and 9.3 months, respectively. Grade 3 or 4 AEs were seen in 70% of patients. Conclusion: Second-line GnP after FX failure for patients with APC could be more effective than GEM alone. Further comparison studies are warranted.

Abstract Background The aim of this study was to evaluate the efficacy and safety of first-line chemotherapy with re-introduction of oxaliplatin (OX) more than 6 months after adjuvant chemotherapy including OX. Methods Stage II/III colon cancer patients with neuropathies of grade ≤ 1 who relapsed more than 6 months after adjuvant chemotherapy including OX were considered eligible. Eligible patients were treated with 5-fluorouracil, l-leucovorin and OX plus molecularly targeted agents or capecitabine and OX plus bevacizumab (BV) or S-1 and OX plus BV. The primary endpoint was the progression-free survival (PFS), and the secondary endpoints were the overall survival (OS), response rate (RR) and toxicity. Results A total of 50 patients were enrolled between September 2013 and May 2019. Twelve patients received 5-fluorouracil, l-leucovorin and OX (FOLFOX) plus BV, 21 patients received capecitabine and OX plus BV, 10 patients received S-1 and OX plus BV and 7 patients received FOLFOX plus cetuximab or panitumumab. The median PFS was 11.5 months (95% confidence interval [CI] 8.3–16.0), the median OS was 45.4 months (95% CI 37.4–NA), and the RR was 56.0% (95% CI 42.3–68.8). Adverse events of grade ≥ 3 that occurred in ≥ 5% of cases were neutropenia in 6 patients (12%), peripheral sensory neuropathy in 5 patients (10%), diarrhea in 4 patients (8%), hypertension in 4 patients (8%), anorexia in 3 patients (6%) and allergic reactions in 3 patients (6%). Conclusions First-line chemotherapy with re-introduction of OX more than 6 months after adjuvant chemotherapy including OX can be used safely with expected efficacy for relapsed colon cancer patients.

<b><i>Introduction:</i></b> Patients with advanced pancreatic cancer have a poor prognosis. FOLFIRINOX (FFX) and gemcitabine plus nab-paclitaxel (GnP) have been established as first-line treatment, but they have not been confirmed as second-line treatment after FFX. The aim of this study was to evaluate the safety and efficacy of GnP as second-line therapy after FFX in patients with unresectable pancreatic cancer. <b><i>Methods:</i></b> Twenty-five patients with unresectable pancreatic cancer were enrolled. The patients were treated with GnP after FFX between September 2015 and September 2019. Tumor response, progression-free survival (PFS), overall survival (OS), and incidence of adverse events were evaluated. <b><i>Results:</i></b> The response rate, disease control rate, median PFS, and median OS were 12%, 96%, 5.3 months, and 15.6 months, respectively. The common grade 3 or 4 adverse events were neutropenia (76%) and anemia (16%). <b><i>Conclusions:</i></b> GnP after FOLFIRINOX is expected to be one of the second-line recommendations for patients with unresectable pancreatic cancer.

AIM: To evaluate and compare the cytograding of breast cancers using Robinson's and Moriquand's grading methods MATERIAL AND METHODS: This study was a cross-sectional retrospective study conducted over a period of three years w. e .f October 2014 to October 2017 and includes diagnosed or highly suspicious malignant cases of breast carcinoma. Slides were retrieved from the cytology section of Department of Pathology, GMC Jammu. A total of 84 cases of breast cancers were studied and grading was done using Robinson's and Mouriquand's methods and the two grading methods were then compared. RESULTS: Out of 84 cases of breast cancers , on using Robinson's grading method , 11 cases [13.10%] were graded as grade 1, 65 cases [77.38%] were graded as grade 2 and 8 cases [9.52%] cases as grade 3. 9 (10.71%) cases are graded as Grade I by Mouriquand's method with score less than 5. 68(80.95%) cases were graded as Grade II with score 5-9 and 7 (8.33%) were graded ad Grade III with score ≥10. On doing comparison between the two cytograding methods, we found a high degree of concordance between the two systems [ 96.42% ] . The relationship observed between the scores obtained by the two methods was also seen to be highly signicant. CONCLUSION: There is possibility of comprehensive cytograding of breast cancers by using the two different methods proposed by Robinson's and Moriquand's but out of the two methods inspite of a high degree of concordance between the two methods , the grading system of Robinson's because of its more objective set of criterias and easy reproducibility has been found to be easier and better.
