Necrotic Change

425 Background: Primary lesion in mRCC often shows necrotic change or only density changes to targeted therapy. As most clinical trials for mRCC have enrolled nephrectomized patients (pts), there is no consensus on including primary lesion in target lesion when evaluating response. We investigated whether best overall response (OR) changes when designate target lesions with or without primary lesion, and such discordance lead to difference in predictive value in terms of time to progression (TTP) and overall survival (OS). Methods: We enrolled mRCC pts with intact primary lesion, at least one measurable metastatic lesion, and proper image data who had received sunitinib in our institution between 2003 and 2011. We documented the variation of the sum of the largest diameters (ΔSLD) with all target lesions and with metastasis-only target lesions separately. Response evaluation was calculated with RECIST v1.1. Results: Of 41 pts, 38 received sunitinib as 1st line treatment and 3 did as 2nd line. The most frequent metastatic site was lung (63.4%) followed by lymph node (46.3%) and bone (42.5%). Median ΔSLD of primary lesion and metastatic target lesion were -6.02% (range: -34.00 to 17.60%), and -18.03% (-100.00 to 120.00%). On response evaluation with metastasis-only target lesions, best OR of 2 pts (4.87%) changed from stable disease to partial response. When categorize pts into responders and non-responders, metastasis-only target lesions resulted in significantly better discrimination of TTP (14.949 vs 4.271 mo, p=0.01) and OS (18.497 vs 9.561 mo, p=0.036) between two groups. Using all target lesions, both TTP (14.949 vs 5.355 mo, p=0.056) and OS (17.971 vs 10.579 mo, p=0.155) were statistically insignificant. Conclusions: Our study showed discordance in OR between using all target lesions and using metastasis-only target lesions, and metastasis-only target lesion could have more accurate predictive value. As response rate is often used as an end point in clinical research of mRCC, further discussion is needed whether primary lesion should be included or not in target lesion. [Table: see text]

Objectives:Antiangiogenic strategies have demonstrated efficacy in epithelial ovarian cancer (EOC). Sorafenib is a novel multitargeted kinase inhibitor with antiangiogenic activity. Gemcitabine has known activity against EOC. A phase 1 clinical trial of this combination suggested activity in ovarian cancer with no dose-limiting toxicity. This phase 2 study was designed to examine the safety and efficacy of gemcitabine and sorafenib in patients with recurrent EOC.Methods:Patients with recurrent EOC after platinum-based chemotherapy and who had subsequently received up to 3 prior chemotherapy regimens were eligible. Gemcitabine (1000 mg/m2 intravenous [IV]) was administered weekly for 7 of 8 weeks in the first cycle, then weekly for 3 weeks of each subsequent 4-week cycle. Sorafenib (400 mg p.o. bid) was given continuously. The primary end point for this trial was objective response rate by the Response Evaluation Criteria in Solid Tumors. Secondary endpoints included Gynecologic Cancer Intergroup (GCIG) CA-125 response, time to progression, overall survival, and toxicity.Results:Forty-three patients were enrolled, and 33 completed at least 1 cycle. Two patients had a partial response (Response Evaluation Criteria in Solid Tumors objective response rate = 4.7%). Ten patients (23.3%) maintained response or stable disease for at least 6 months. GCIG CA-125 response was 27.9%. The median time to progression was 5.4 months, and the median overall survival was 13.0 months. Hematologic toxicity was common but manageable. The most common nonhematologic adverse events were hand-foot syndrome, fatigue, hypokalemia, and diarrhea.Conclusion:This trial of gemcitabine and sorafenib in recurrent EOC did not meet its primary efficacy end point, but the combination was associated with encouraging rates of prolonged stable disease and CA-125 response.

Purpose To assess the efficacy and toxicity of the marine-derived alkaloid trabectedin (ET-743) in patients with advanced ovarian cancer refractory to or experiencing disease relapse after platinum- and taxane-based chemotherapy. Patients and Methods Fifty-nine patients from four institutions either resistant (n = 30) or sensitive (n = 29) to prior platinum and taxanes were treated with a 3-hour infusion of trabectedin every 3 weeks. Patients were monitored weekly for toxicity and restaged every two cycles for response. Response was assessed according to Response Evaluation Criteria in Solid Tumors Group. Results The peer-reviewed objective response rate in platinum-sensitive patients was 43% (95% CI, 23% to 65%) with an estimated median time to progression of 7.9 months (95% CI, 7.5 to 14.1 months); in platinum-resistant patients two partial responses were observed. Responses were durable for up to 12.9 months (median, 5 months). The predominant toxicities at the recommended dose of 1,300 μg/m2 were neutropenia, asthenia, and self-limited increase of aminotransferases never requiring treatment interruption. Conclusion Trabectedin administered as a 3-hour infusion at 1,300 μg/m2 is a safe new drug with promising activity in relapsed ovarian cancer, showing a 43% objective response rate in patients with platinum-sensitive disease, which favorably compares with other salvage treatments and warrants additional development either alone or in combination.

Ziel Die Chemosaturation mittels perkutaner hepatischer Perfusion mit Melphalan (CS-PHP) ist ein palliatives Therapieverfahren für Patienten mit nicht kurativ behandelbaren Lebertumoren. Die CS-PHP erlaubt eine selektive intrahepatische Anreicherung von hochdosiertem Melphalan bei minimaler systemischer Toxizität durch venöse Hämofiltration. Ziel dieser Studie war es, das Ansprechen und Überleben sowie die Sicherheit der CS-PHP-Prozedur bei Patienten mit leberdominant metastasiertem Aderhautmelanom zu evaluieren. Material und Methoden Gesamtansprechrate (overall response rate, ORR) und Krankheitskontrollrate (disease control rate, DCR) wurden anhand von Response Evaluation Criteria In Solid Tumors (RECIST1.1) ermittelt. Medianes Gesamtüberleben (mOS), medianes progressionsfreies Überleben (mPFS) und hepatisches mPFS (mhPFS) wurden mittels Kaplan-Meier-Schätzer ermittelt. Nebenwirkungen wurden entsprechend der einheitlichen Terminologie-Kriterien für Nebenwirkungen (CTCAE) v5 klassifiziert. Ergebnisse 30 Patienten wurden zwischen Oktober 2014 und Januar 2019 mit 70 Chemosaturationen behandelt. Die ORR betrug 42,3 % und die DCR 80,8 %. Das mOS betrug 12 (95 %-Konfidenzintervall (KI) 7–15) Monate, das mPFS 6 (95 %-KI 4–10) und das mhPFS ebenfalls 6 (95 %-KI 4–13) Monate. Signifikante, aber transiente hämatotoxische Nebenwirkungen waren häufig (87 % Grad-3/4-Thrombozytopenie), hepatische Toxizität bis Leberversagen (n = 1/70) sowie kardiovaskuläre Komplikationen (ischämischer Insult, n = 1/70) waren selten. Schlussfolgerung Das palliative Therapiekonzept der Chemosaturation ist bei Patienten mit hepatisch metastasiertem Aderhautmelanom effektiv. Die interventionelle Prozedur ist sicher, seltene, aber schwerwiegende kardiovaskuläre und hepatische Komplikationen erfordern eine sorgfältige Patientenselektion und intensive Aufmerksamkeit.

AbstractThis analysis assessed the efficacy and safety of lenalidomide + dexamethasone in patients with relapsed or refractory multiple myeloma (MM) previously treated with thalidomide. Of 704 patients, 39% were thalidomide exposed. Thalidomide-exposed patients had more prior lines of therapy and longer duration of myeloma than thalidomide-naive patients. Lenalidomide + dexamethasone led to higher overall response rate (ORR), longer time to progression (TTP), and progression-free survival (PFS) versus placebo + dexamethasone despite prior thalidomide exposure. Among lenalidomide + dexamethasone-treated patients, ORR was higher in thalidomide-naive versus thalidomide-exposed patients (P = .04), with longer median TTP (P = .04) and PFS (P = .02). Likewise for dexamethasone alone-treated patients (P = .03 for ORR, P = .03 for TTP, P = .06 for PFS). Prior thalidomide did not affect survival in lenalidomide + dexamethasone-treated patients (36.1 vs 33.3 months, P > .05). Thalidomide-naive and thalidomide-exposed patients had similar toxicities. Lenalidomide + dexamethasone resulted in higher rates of venous thromboembolism, myelosuppression, and infections versus placebo + dexamethasone, independent of prior thalidomide exposure. Lenalido-mide + dexamethasone was superior to placebo + dexamethasone, independent of prior thalidomide exposure. Although prior thalidomide may have contributed to inferior TTP and PFS compared with thalidomide-naive patients, these parameters remained superior compared with placebo + dexamethasone; similar benefits compared with placebo + dexamethasone were not evident for thalidomide-exposed patients in terms of overall survival. Studies were registered at http://www.clinicaltrials.gov under NCT00056160 and NCT00424047.

Unresectable nodular and diffuse hepatocellular carcinoma (HCC) have a poor prognosis with limited treatment options. Systemic traditional chemotherapy has been only rarely reported, with unsatisfactory results. The aim of this prospective, non-randomized, non-blinded, single center clinical trial was to investigate safety profile, objective response rate, time to progression and overall survival of sorafenib in comparison with metronomic chemotherapy (MC) consisting of thalidomide, piroxicam and cyclophosphamide in dogs with advanced, unresectable HCC. Between December 2011 and June 2017, 13 dogs were enrolled: seven received sorafenib, and six were treated with MC. Median time to progression was 363 days (95% CI, 191–535) in dogs treated with sorafenib versus 27 days (95% CI, 0–68) in dogs treated with MC (p = 0.044). Median overall survival was 361 days (95% CI, 0–909) in dogs receiving sorafenib, while 32 days (95% CI, 0–235) in those receiving MC (p = 0.079). Sorafenib seems to be a good candidate for the treatment of dogs with advanced HCC, due to a benefit in disease control and an acceptable safety profile, offering a good basis on which new randomized prospective clinical trials should be undertaken to compare the efficacy and drawback of sorafenib versus MC or traditional chemotherapy.

PURPOSE: Twenty-one–day topotecan infusion was administered as second-line therapy in patients with previously treated ovarian cancer (based on our prior favorable phase I experience) to determine its activity, time to progression, and pharmacodynamics. PATIENTS AND METHODS: Ovarian cancer patients with measurable lesions and one prior platinum-containing regimen were eligible. Topotecan 0.4 mg/m2/d 21-day continuous ambulatory intravenous infusion, with appropriate dose modifications for toxicity, was administered every 28 days. Weekly blood levels of topotecan and topoisomerase-1 (topo-1) levels in peripheral-blood mononuclear cells (PBMCs) were determined for pharmacodynamic correlation. RESULTS: Twenty-four patients were entered onto the study (six cisplatin-refractory, five relapsing within < 6 months and 13 relapsing > 6 months after platinum-based therapy). A total of 128 cycles of topotecan (median, four cycles per patient; range, one to 12 cycles) were administered. The major toxicity was neutropenia (29% grade 3 in all cycles and 4% grade 4). One episode of grade 4 thrombocytopenia (4%) occurred. Fifty-two percent of the patients had anemia that required transfusions. Eight of 23 patients with measurable disease (35%; 95% confidence interval [CI], 15% to 54%) had partial responses (PRs) lasting longer than 1 month. Two of these patients had minor residual computed tomographic changes but had clinical complete remissions that lasted up to 53 weeks while they were not undergoing further therapy. One patient with nonmeasurable disease had a PR (by CA-125 criteria) that lasted 6 months, for an overall response rate of 38% in nine of 24 patients (95% CI, 18% to 57%). The median time to progression was 26 weeks. Pharmacodynamic analysis demonstrated a statistically significant decrease in free PBMC topo-1 level at weeks 2 and 3 of drug administration. There was a strong statistical correlation between the decrease in free topo-1 levels and increasing area under the curve (AUC) for topotecan. This was confirmed in a pharmacodynamic model. CONCLUSION: Twenty-one–day infusion is a well-tolerated method of administering topotecan. Pharmacodynamic studies demonstrate correlations between (1) the week of infusion and the PBMC topo-1 level, (2) the AUC of topotecan and the decrease in topo-1 levels, and (3) the change in topo-1 level and the neutrophil nadir. The objective response rate of 35% to 38% (95% CI, 15% to 57%) in this small multicenter study is at the upper level for topotecan therapy in previously treated ovarian cancer. Prolonged topotecan administration therefore warrants further investigation in larger, randomized studies comparing this 21-day schedule with the once-daily-for-5-days schedule.

PURPOSE: Approximately 60% of patients with small-cell lung cancer (SCLC) develop brain metastases. Whole-brain radiotherapy (WBRT) gives symptomatic improvement in more than 50% of these patients. Because brain metastases are a sign of systemic progression, and chemotherapy was found to be effective as well, it becomes questionable whether WBRT is the only appropriate therapy in this situation. PATIENTS AND METHODS: In a phase III study, SCLC patients with brain metastases were randomized to receive teniposide with or without WBRT. Teniposide 120 mg/m2 was given intravenously three times a week, every 3 weeks. WBRT (10 fractions of 3 Gy) had to start within 3 weeks from the start of chemotherapy. Response was measured clinically and by computed tomography of the brain. RESULTS: One hundred twenty eligible patients were randomized. A 57% response rate was seen in the combined-modality arm (95% confidence interval [CI], 43% to 69%), and a 22% response rate was seen in the teniposide-alone arm (95% CI, 12% to 34%) (P < .001). Time to progression in the brain was longer in the combined-modality group (P = .005). Clinical response and response outside the brain were not different. The median survival time was 3.5 months in the combined-modality arm and 3.2 months in the teniposide-alone arm. Overall survival in both groups was not different (P = .087). CONCLUSION: Adding WBRT to teniposide results in a much higher response rate of brain metastases and in a longer time to progression of brain metastases than teniposide alone. Survival was poor in both groups and not significantly different.
