Kaposi sarcoma is an angioproliferative disease associated with human herpes virus 8 infection. Classic Kaposi sarcoma (CKS) usually develops in older age. Although CKS often does not require systemic therapy, systemic therapy can be administered in progressively symptomatic patients. In this real-life study, we purposed to determine effectiveness and safety of weekly paclitaxel therapy in the first-line treatment of CKS. In this cross-sectional retrospective study, we analyzed the clinical data of 44 patients with CKS who received first-line paclitaxel therapy between January 2000 and December 2020. Paclitaxel was administered by intravenous infusion 80 to 100 mg/weekly. The median age of the patients was 67 years (range, 39–86 years), and majority male (77.2%). All patients had cutaneous involvement in extremities. The median follow-up time from paclitaxel treatment was 39.1 (range, 3.7–173.5) months. The median progression free survival from start of therapy was 35.1 months (range, 2–144 months). Complete response, partial response and stable disease were observed in 7 (15.9%), 28 (63.7%) and 6 (13.6) patients, respectively. Objective control rate was 79.6%, and the median response time after the last dose of paclitaxel was 18.2 months. A total of 4 patients (9.1%) had grade 3 to 4 neutropenia, but it was not complicated by febrile neutropenia. Three patients (6.8%) experienced grade 3 to 4 peripheral neuropathy. No patient had grade 3 to 4 allergic reaction. There was no drug-related death. According to our results, paclitaxel is an effective therapy option with an acceptable safety profile for patients with advanced CKS.
The purpose of the study was to assess the prognosis of HER2-positive metastatic breast cancer patients who received trastuzumab beyond progression and investigate the predictors of complete response. HER2-positive metastatic breast cancer patients who received long-term trastuzumab were included in the study. Predictors of complete response were analyzed with binary regression analysis. The prognosis of patients who had their trastuzumab-based treatment terminated was assessed. Eighty patients were involved in the study. The patients were received with trastuzumab for a median of 62 months (12–191). A complete response was observed in 60 (75%) patients. The median duration to development of complete response was found as 14.8 months (2.4–55). In logistic regression analysis: using endocrine therapy with trastuzumab (p = 0.04), menopausal status (p = 0.03), and the number of metastatic sites (p = 0.01) were found to be statistically significant factors for a complete response. Trastuzumab-based therapy of fifteen patients was terminated, six (40%) patients continued to receive an aromatase inhibitor, and nine (60%) patients were followed up without treatment. After termination of trastuzumab, at a median follow-up of 32 months (11–66), recurrence was detected in two (13.3%) patients. We detected that menopausal status, the number of metastatic sites, and using endocrine therapy with trastuzumab were predictors of complete response in HER2-positive metastatic breast cancer patients who received long-term trastuzumab-based therapy. We observed that HER2-positive metastatic breast cancer patients may be completely cured with trastuzumab-based therapy. There are no defined criteria for termination of trastuzumab treatment in this selected patient group. It is necessary to confirm our data with multicenter studies involving a large number of patients.
e17509 Background: SOLO-2 trial results have proven the efficacy of Olaparib in BRCA-mutant platinum-sensitive relapsed ovarian cancer patients. LynTurk as an open label, multi-center study, designed to show the real world safety and efficacy results of Turkey Olaparib managed access program. Methods: Patients with BRCA mutated relapsed ovarian cancer who are in complete or partial response following platinum based chemotherapy were eligible for Olaparib maintenance in Turkish managed access program. The primary aim was safety. Progression free survival, overall survival were the secondary endpoints. Results: Between December 2014 and March 2021, 48 patients were accepted for program. Due to immaturity of data, in this report, a total of 26 patient results were analyzed. BRCA2 mutation was present in 5 patients, one patient have both BRCA1 and BRCA2 mutations; 20 cases were found to be BRCA1 mutated. The median age of patients was 51 (29-61) years. All patients have high grade serous adenocarcinoma of ovary or primary peritoneal carcinoma. The most common site of involvement are lymph nodes and peritoneal surfaces; in 11% of cases there are liver parenchyma metastasis. All of the patients received at least two lines of platinum-based chemotherapy; median 3 lines (2-4) of treatment were applied before Olaparib maintenance. Previous bevacizumab treatment was allowed in this program, 53.8% of cases were received at least 3 cycles, maintenance bevacizumab was given to 12 patients. Median treatment duration with Olaparib was 26,2 months (3-80m). In 30.7% of cases no adverse events were noted, at least one level dose reduction was needed for 50% of patients due to toxicity. Hematological adverse events were the mostly encountered followed by dyspepsia and fatigue. Anemia was the reason for permanent drug discontinuation in 2 patients (0.7%). No febrile neutropenia was reported. During the follow-up, no secondary malignancy and pneumonitis was noted. Median progression free survival from the end of last chemotherapy was 19.3 months. One-year PFS rate was 88.4% and 2-y PFS rate was 53.8%. One-year OS rate from the end of chemotherapy was 92.3% and 2-year was 61.5%. Conclusions: The real world data from Turkey managed access program has showed that Olaparib has a safety profile in paralel with clinical trials (SOLO). No new safety signals were reported. Although a heterogenous population including heavily pretreated patients, maintenance Olaparib was found effective. This report will be updated as the data of all intent to treat population will gather and will get mature.
Amaç: Parafoliküler C hücrelerinden kaynaklanan medüller tiroid karsinomu (MTC) oldukça nadir bir endokrin tümördür. Hastalığın en özgün yanı %25 ailesel olması ve multiple endokrin neoplazi 2 sendromlarının komponenti olmasıdır. Cerrahi rezeksiyon erken evrelerde küratif potansiyele sahiptir. Rezeke edilemeyen veya ileri evre hastalıkta sistemik tedavi seçenekleri mevcuttur. Hastalığın nadir ve sınırlı tedavi seçeneklerinin olması nedeniyle merkezimizde takip edilen hastalarımızın sonuçlarını paylaşmayı uygun bulduk. Gereç veYöntem: Haziran 2000 ile Haziran 2019 arasında 47 progresif MTC hastası çalışmaya dahil edildi. Hastaların demografik ve klinik özellikleri ile tedavi sonuçları değerlendirildi. Sağkalım ile ilişkili risk faktörlerini belirlemek için istatistiksel analizler yapıldı.Bulgular: Ortanca yaş 46 yıl ve erkek/kadın oranı 32/15 idi. Tüm hastaların Doğu Kooperatifi Onkoloji Grubu -Performans Statüsü (ECOG-PS) 0 (%66,7) veya 1 (%33,3) idi. Hastaların %73'ünde ilk tanı anında lenf nodu metastazı görülürken, %22'sinde uzak organ metastazı vardı. Lokal nüks
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
