This is a nice, practical study showing that when considering liver directed therapy, options in metastatic CRC, CT’s alone are insufficient and contrasted MRI can be helpful. More than 30% of patients had care that was impacted using MRI prior to any therapeutic decisions.
For our NSCLC patients who carry a driver EGFR mutation, there seems to be little/no benefit of the addition of IO therapy to standard chemotherapy in the second line setting. Prior post hoc analyses showed a trend favoring immunotherapy (IO) therapy in those only having received one prior line of therapy and those with sensitizing EGFR mutations, however this was not confirmed in this randomized phase III study.
This is a Chinese study of neoadjuvant camrelizumab (PD1-MAb) + platinum-based chemo showing impressive effectiveness with an overall response rate (ORR) of 83% and a complete response (CR) of 19%. This drug is being studied in esophageal-SCC with promising reports as well. We will see if this gets studied in a Western population.
This is a negative study looking at atezolizumab + chemo vs. chemo alone in metastatic urothelial carcinoma. In the same issue, there is a negative study on atezolizumab vs. chemo alone, as well. It does seem that atezolizumab has limited disease activity versus some comparable agents.
Initial results from the DUO-E study in metastatic endometrial cancer. The preliminary report suggests that maintenance durvalumab and maintenance durvalumab + olaparib were superior to standard observation after systemic carbo/taxol. As the trial data matures, the question will be: is this in all patients or driven by those with dMMR or HDR mutations?
Negative study for the use of HIPEC in the adjuvant setting of high-risk or locally advanced colorectal cancers, including those with perforation and peritoneal invasion. HIPEC doesn’t seem to reduce the risk of peritoneal recurrence after potentially curative resection.
This is a study showing tumor agnostic activity of trastuzumab deruxtecan (T-DXd) with an all-comer overall response rate (ORR) of 37.1%, duration of response (DOR) of 11.3 months and an overall survival (OS) of 13.4 months in an otherwise heavily pre-treated group. Those with IHC-3+ derived larger benefit than 2+. Patients with ERBB2 mutations who had no expression of HER2 were excluded from the trial.
From our radiation oncology colleagues, this is a study showing that for high-risk bone metastases, those treated prophylactically with radiation were associated with lower rates of skeletal related events. High risk was defined as a bulky (>2cm) lesion in the hip, long bone lesions occupying one-third (1/3) to two-thirds (2/3) of the cortical thickness, or disease of the vertebral body of the junctional spine or posterior element involvement.
This study demonstrates activity of osimertinib in uncommon EGFR mutations. Of note, these were non-exon-20 mutations and included some with compound mutations. Response rates were reasonable and this justifies using targeted therapy in these uncommon subgroups.
This gives more credence to the idea of avoiding bendamustine before CAR T therapy. Patients exposed to bendamustine had about a 20% lower overall response rate (ORR), 50% shorter progression-free survival (PFS) and >50% shorter overall survival (OS) compared to those who were bendamustine naive. Although other factors may also play a role here, these seem to be significant differences and should make it clear that one should not use this drug before pursuing CAR T therapy.
FCS Hematology Oncology Review creates a platform for our physician network to observe the most recent articles and studies available in the oncology and hematology world. By sharing these articles we are building our wealth of knowledge of new observations and treatments as they come available.
