Neoadjuvant chemotherapy and radiation followed by surgical resection of the rectum is a standard treatment for locally advanced rectal cancer. A subset cancer caused deficiency in mismatch repair. Because repair-deficient colorectal responsive to programmed death 1 (PD-1) blockade context metastatic disease, it was hypothesized that checkpoint could be effective patients with repair-deficient,

SUMMARY The PI3K/AKT/mTOR pathway is commonly activated in non-small-cell lung cancer. It plays important roles promoting oncogenesis cancer and mediating resistance to EGF receptor tyrosine kinase inhibitors. Targeted agents against the components of this are currently development their clinical benefits remain be defined. This review provides an overview dysregulation novel targeting In addition, potential predictive biomarkers guiding patient selection for targeted inhibition also discussed.

62 Background: Trastuzumab stimulates HER2-specific T cell responses and increases tumor PD-L1 expression, anti-PD-1 antibody can help enhance cell-specific immunity of trastuzumab. Oxaliplatin further T-cells by activating dendritic cells. We conducted a phase II trial pembrolizumab with chemotherapy/trastuzumab. Methods: Patients previously untreated HER2 IHC 3+ or FISH+ tumors irrespective status received intravenous P 200 mg flat dose, 6 mg/kg (after 8 load), O 130 mg/m2 every 3 weeks...

Background Patients with germline/somatic BRCA1/BRCA2 mutations (g/s BRCA1/2 ) comprise a distinct biologic subgroup of pancreas ductal adenocarcinoma (PDAC). Methods Institutional databases were queried to identify patients who had PDAC g/s . Demographics, clinicopathologic details, genomic data (annotation s according precision oncology knowledge base for somatic mutations), zygosity, and outcomes abstracted. Overall survival (OS) was estimated using the Kaplan‐Meier method. Results In...

16 Background: Total neoadjuvant therapy with induction chemotherapy and chemoradiation (chemoRT) is the standard treatment for locally advanced rectal adenocarcinomas. Mismatch repair deficient (dMMR) tumors respond poorly to chemotherapy. PD-1 blockade effective in patients metastatic dMMR colorectal cancers, but its efficacy has not been established setting. The purpose of this study evaluate clinical benefit cancer. Methods: We designed a prospective, single-arm, phase II which stage III...

<h3>Importance</h3> Predicting outcomes in patients receiving neoadjuvant therapy for rectal cancer is challenging because of tumor downstaging. Validated clinical calculators that can estimate recurrence-free survival (RFS) and overall (OS) among with who have received multimodal are needed. <h3>Objective</h3> To develop validate providing estimates recurrence better individualized decision-making than the American Joint Committee on Cancer (AJCC) staging system or (NAR) score. <h3>Design,...

Importance Clonal hematopoiesis (CH) has been associated with development of atherosclerosis and leukemia worse survival among patients cancer; however, the association cancer therapy efficacy, in particular immune checkpoint blockade (ICB), toxicity not yet established. Given widespread use ICB critical role hematopoietic stem cell–derived lymphocytes play mediating antitumor responses, CH may be therapeutic efficacy hematologic toxicity. Objective To determine between outcomes, toxicity,...

355 Background: We previously evaluated adding D, an anti-PD-L1 antibody, to PET-directed CRT and found the combination be safe promising in terms of pathologic response survival outcomes. 1 Here, we add T combination. Methods: Pts with locally advanced esophageal/GEJ adenocarcinoma were enrolled. received 2 cycles mFOLFOX6 prior repeat PET/CT. PET responders (≥35% reduction SUV (PETr)) 5-FU/capecitabine oxaliplatin RT, while induction non-responders (PETnr) carboplatin/paclitaxel RT. All...

Background: Abdominoperineal resection (APR) has been advocated for persistent or recurrent disease after failure of chemoradiation (CRT) anal squamous cell cancer (SCC). Treatment with salvage APR can potentially achieve a cure. This study aimed to analyze oncological outcomes in recent time period at comprehensive center. Methods: A retrospective review all patients who underwent biopsy-proven SCC between 1 January 2007 and 31 December 2020 was performed. Patients stage IV the initial...

Some patients with previously treated, unresectable, recurrent or metastatic head and neck malignancies are not amenable to curative-intent treatment. Here, we investigated the quad-shot (RTOG 8502) regimen of hypofractionated proton radiotherapy (RT) in that patient population. From 2013 2015, 26 cancers were treated palliative RT quad shot (3.7 Gy twice daily for 2 days). Patient characteristics survival data reviewed. Seventeen (65%) received ≥ 3 cycles 23 (88%) had prior RT. Overall...
