FGFR1 and NTRK3 actionable alterations in “Wild-Type” gastrointestinal stromal tumors

BACKGROUND: About 10–15% of adult, and most pediatric, gastrointestinal stromal tumors (GIST) lack mutations in KIT, PDGFRA, SDHx, or RAS pathway components (KRAS, BRAF, NF1). The identification of additional mutated genes in this rare subset of tumors can have important clinical benefit to identify altered biological pathways and select targeted therapies. METHODS: We performed comprehensive genomic profiling (CGP) for coding regions in more than 300 cancer-related genes of 186 GISTs to assess for their somatic alterations. RESULTS: We identified 24 GIST lacking alterations in the canonical KIT/PDGFRA/RAS pathways, including 12 without SDHx alterations. These 24 patients were mostly adults (96%). The tumors had a 46% rate of nodal metastases. These 24 GIST were more commonly mutated at 7 genes: ARID1B, ATR, FGFR1, LTK, SUFU, PARK2 and ZNF217. Two tumors harbored FGFR1 gene fusions (FGFR1–HOOK3, FGFR1–TACC1) and one harbored an ETV6–NTRK3 fusion that responded to TRK inhibition. In an independent sample set, we identified 5 GIST cases lacking alterations in the KIT/PDGFRA/SDHx/RAS pathways, including two additional cases with FGFR1–TACC1 and ETV6–NTRK3 fusions. CONCLUSIONS: Using patient demographics, tumor characteristics, and CGP, we show that GIST lacking alterations in canonical genes occur in younger patients, frequently metastasize to lymph nodes, and most contain deleterious genomic alterations, including gene fusions involving FGFR1 and NTRK3. If confirmed in larger series, routine testing for these translocations may be indicated for this subset of GIST. Moreover, these findings can be used to guide personalized treatments for patients with GIST. Trial registration NCT 02576431.

Perceived Impact of Urologic Surgery Training Program Modifications due to COVID-19 in the United States

ObjectiveTo assess urology residency program modifications in the context of COVID-19, and perceptions of the impact on urology trainees.MethodsA cross-sectional survey of program leadership and residents at accredited US urology residencies was administered between April 28, 2020 to March 11, 2020. Total cohort responses are reported, and subanalyses were preformed comparing responses between those in in high vs low COVID-19 geographic regions, and between program leaders vs residents.ResultsProgram leaders from 43% of programs and residents from 18% of programs responded. Respondents reported decreased surgical volume (83%-100% varying by subspecialty), increased use of telehealth (99%), a transition to virtual educational platforms (95%) and decreased size of inpatient resident teams (90%). Most residents are participating in care of COVID-19 patients (83%) and 20% endorsed that urology residents have been re-deployed. Seventy nine percent of respondents perceive a negative impact of recent events on urology surgery training and anxiety regarding competency upon completion of residency training was more pronounced among respondents in high COVID-19 regions.ConclusionMajor modifications to urology training programs were implemented in response to COVID-19. Attention must be paid to the downstream effects of the training disruption on urology residents

Cost-Effectiveness Analysis of Elective Neck Dissection in Patients With Clinically Node-Negative Oral Cavity Cancer.

Purpose Recently, a large randomized trial found a survival advantage among patients who received elective neck dissection in conjunction with primary surgery for clinically node-negative oral cavity cancer compared with those receiving primary surgery alone. However, elective neck dissection comes with greater upfront cost and patient morbidity. We present a cost-effectiveness analysis of elective neck dissection for the initial surgical management of early-stage oral cavity cancer. Methods We constructed a Markov model to simulate primary, adjuvant, and salvage therapy; disease recurrence; and survival in patients with T1/T2 clinically node-negative oral cavity squamous cell carcinoma. Transition probabilities were derived from clinical trial data; costs (in 2015 US dollars) and health utilities were estimated from the literature. Incremental cost-effectiveness ratios, expressed as dollar per quality-adjusted life-year (QALY), were calculated with incremental cost-effectiveness ratios less than $100,000/QALY considered cost effective. We conducted one-way and probabilistic sensitivity analyses to examine model uncertainty. Results Our base-case model found that over a lifetime the addition of elective neck dissection to primary surgery reduced overall costs by$6,000 and improved effectiveness by 0.42 QALYs compared with primary surgery alone. The decrease in overall cost despite the added neck dissection was a result of less use of salvage therapy. On one-way sensitivity analysis, the model was most sensitive to assumptions about disease recurrence, survival, and the health utility reduction from a neck dissection. Probabilistic sensitivity analysis found that treatment with elective neck dissection was cost effective 76% of the time at a willingness-to-pay threshold of $100,000/QALY. Conclusion Our study found that the addition of elective neck dissection reduces costs and improves health outcomes, making this a cost-effective treatment strategy for patients with early-stage oral cavity cancer

Correlation of liver and pancreas tumor motion with normal anatomical structures determined with deformable image registration

Purpose. The inherent difficulty of identifying liver and pancreas tumors without intravenous contrast creates the need for implanted metal fiducials to visualize tumor position and motion in stereotactic body radiation therapy (SBRT). Unfortunately, the invasive procedure of implanting fiducials carries a risk of toxicity, introduces a treatment delay, and creates streak artifacts on treatment planning images, which can hinder tumor identification. A fiducial-less motion management strategy would improve the safety, tolerability, and availability of abdominal SBRT. We hypothesized that upper abdominal tumor motion would correlate with the motion of nearby organs and could thereby serve as a fiducial-less proxy for tumor motion. Methods. We retrospectively identified fifteen patients with pancreatic cancer or liver cancer treated with SBRT. The liver, superior mesenteric artery, and celiac artery were delineated on 4DCT images and used to predict tumor position. The correlation with tumor motion was quantified with Pearson correlation coefficients (r), and accuracy of the tumor position prediction was expressed as the mean absolute error. Results. The majority of motion with respiration occurred in the superior-inferior (SI) direction with an average of 6.4 mm (range 2.4-11.3 mm) for pancreatic and 13.0 mm (range 6.4-21.2 mm) for liver tumors. In the SI direction we found a tight correlation between liver and tumor motion in pancreas cancer patients (r = 0.92 0.10), and liver tumor patients (r = 0.97 0.02). Using the liver as surrogate, predicted tumor location was on average 0.5 mm from the actual position and not greater than 3.0 mm. Conclusions. This study demonstrates a potential correlation of normal organ and tumor motion which could serve as a fiducial-less surrogate for SBRT in the upper abdomen as on-site 4D volumetric imaging becomes available during treatment. Moving this motion management strategy into the clinic requires additional research to optimize 4D image quality and understand inter-fraction reproducibility

Transdermal Scopolamine for the Prevention of Postoperative Nausea and Vomiting: A Systematic Review and Meta-Analysis

Background: Transdermal scopolamine (TDS) is a potential long-acting prophylactic antiemetic initially developed to prevent motion sickness. TDS is a centrally acting anticholinergic agent that was approved in 2001 by the US Food and Drug Administration for the prevention of postoperative nausea and vomiting (PONV). Although TDS has been reported to be clinically efficacious in the prevention of PONV, several adverse events (AEs), such as sedation, dry mouth, blurred vision, central cholinergic syndrome, and confusion (particularly in elderly patients with mild cognitive impairment), are potential concerns

Randomized controlled trial of a quadratus lumborum block with liposomal bupivacaine for postoperative analgesia in laparoscopic donor nephrectomy.

Perioperative pain management is an important consideration in early recovery and patient satisfaction following laparoscopic donor nephrectomy. Transmuscular quadratus lumborum block has been described to reduce pain and opioid usage following several abdominal surgeries. In this prospective single-blind randomized controlled trial, we compared 52 patients who adhered to our institutional donor nephrectomy Early Recovery After Surgery pathway, which includes a laparoscopic-guided transversus abdominus plane block, to 40 patients who additionally received a transmuscular quadratus lumborum block with liposomal bupivacaine. Compared to control patients, those who received the block spent longer in the operating room prior to the surgical start (65.4 vs. 51.6 min, P < .001). Both groups had similar total hospital length of stay (33.3 h vs. 34.4 h, P = .61). Pain scores from postoperative days 0-30, number of patients requiring opioids, postoperative nausea, and pain management satisfaction were similar between both groups. Patients who received the block consumed less opioid on postoperative day 1 compared to controls (P = .006). No complications were attributable to the block. The quadratus lumborum block provides a safe pain management adjunct for some patients, and may reduce opioid use in the early postoperative period when combined with our standard institutional protocol for kidney donors
