Retreatment with carboplatin and paclitaxel for recurrent endometrial cancer: A retrospective study of the Memorial Sloan Kettering Cancer Center experience.

ABSTRACT: Women with endometrial cancer (EC) frequently receive adjuvant paclitaxel and carboplatin (PC) chemotherapy. There is no standard first line chemotherapy at disease recurrence. Data extrapolated from ovarian cancer has suggested that patients with recurrent EC may benefit from further platinum-based chemotherapy. We performed a retrospective analysis of patients who were retreated with PC chemotherapy for recurrent EC at Memorial Sloan Kettering Cancer Center between January 2000 and December 2014. The median progression free survival (PFS) and overall survival (OS) were estimated using the Kaplan Meier method. Twenty patients were included in the analysis. Patients were re-treated with PC a median of 25 (8-79) months from their original PC. There were no complete responses, 10 (50%) patients had partial response (PR), 3 (15%) had stable disease, 2 (10%) had progression at best response and 5 (20%) were not evaluable by RECIST. A median of 6?cycles of PC were administered (2-9). Four patients (20%) transitioned to paclitaxel only due to carboplatin allergy. At the data cut off, one patient continued PC, and another was off therapy with PR. The remainder (N?=?18, 90%) received a median of 2.5 (1-6) further lines of treatments. Median PFS and OS from re-treatment were 10 and 27?months respectively. Median OS from original diagnosis was 74?months. In this small retrospective study, selected patients with recurrent EC who are >6?months from completion of PC derive benefit from retreatment with PC with a response rate of 50%.

Project description:BackgroundExtraneural metastasis of glioma is a rare event, often occurring in patients with advanced disease. Genomic alterations associated with extraneural glioma metastasis remain incompletely understood.MethodsTen patients at Memorial Sloan Kettering Cancer Center diagnosed with extraneural metastases of glioblastoma (9 patients) and gliosarcoma (1 patient) from 2003 to 2018 were included in our analysis. Patient characteristics, clinical course, and genomic alterations were evaluated.ResultsPatient age at diagnosis ranged from 14 to 73, with 7 men and 3 women in this group. The median overall survival from initial diagnosis and from diagnosis of extraneural metastasis was 19.6 months (range 11.2 to 57.5 months) and 5 months (range 1 to 16.1 months), respectively. The most common site of extraneural metastasis was bone, with other sites being lymph nodes, dura, liver, lung, and soft tissues. All patients received surgical resection and radiation, and 9 patients received temozolomide, with subsequent chemotherapy appropriate for individual cases. 1 patient had an Ommaya and then ventriculoperitoneal shunt placed, and 1 patient underwent craniectomy for cerebral edema associated with a brain abscess at the initial site of resection. Genomic analysis of primary tumors and metastatic sites revealed shared and private mutations with a preponderance of tumor suppressor gene alterations, illustrating clonal evolution in extraneural metastases.ConclusionsSeveral risk factors emerged for extraneural metastasis of glioblastoma and gliosarcoma, including sarcomatous dedifferentiation, disruption of normal anatomic barriers during surgical resection, and tumor suppressor gene alterations. Next steps with this work include validation of these genomic markers of glioblastoma metastases in larger patient populations and the development of preclinical models. This work will lead to a better understanding of the molecular mechanisms of metastasis to develop targeted treatments for these patients.

Project description:BackgroundThe proliferation of relationships between community health systems and academic medical centers has created a need to identify effective components of these models. This article reports on frontline physician experiences, with one such relationship established through the Memorial Sloan Kettering Cancer Center (MSK) Cancer Alliance. MSK created the Alliance with the goals of rapidly bringing the newest standards of care into community settings and increasing patient access to clinical trials in their local communities.MethodsAlliance leadership administered a 10-question anonymous survey to physicians treating patients with cancer across the 3 Alliance member health systems: Hartford HealthCare Cancer Institute, Lehigh Valley Cancer Institute, and Miami Cancer Institute at Baptist Health South Florida. The purpose of the survey was to identify opportunities to improve physician engagement.ResultsThere were 103 clinician respondents across Alliance members, of which 87 reported participation in a disease management team and were included in the final analysis. Most respondents reported high value from Alliance activities, such as attending MSK tumor boards (94%) and lecture series (96%), among those who reported them applicable. Across all respondents, most reported satisfaction with engagement opportunities, such as MSK physician participation in their institution's meetings (76%). When asked where they would like to see increased engagement, the most commonly reported response was for more lecture series (45%). Most respondents (88%) reported that the Alliance led to practice change, either for themselves or for other clinicians at their institution. Many attributed this practice change to MSK disease-specific process measures.ConclusionsThe activities most valued by community physicians were heavily physician relationship-based. The encouraging experience of the MSK Cancer Alliance suggests that activities involving physician investment may be effective for promoting practice change in the context of cross-institution relationships. Future research is needed in this area.
