Background: Accurate and efficient triage is crucial for prioritizing care and managing resources in emergency rooms. This study investigates the effectiveness of ChatGPT, an advanced artificial intelligence system, in assisting health providers with decision-making for patients presenting with metastatic prostate cancer, focusing on the potential to improve both patient outcomes and resource allocation. Methods: Clinical data from patients with metastatic prostate cancer who presented to the emergency room between 1 May 2022 and 30 April 2023 were retrospectively collected. The primary outcome was the sensitivity and specificity of ChatGPT in determining whether a patient required admission or discharge. The secondary outcomes included the agreement between ChatGPT and emergency medicine physicians, the comprehensiveness of diagnoses, the accuracy of treatment plans proposed by both parties, and the length of medical decision making. Results: Of the 147 patients screened, 56 met the inclusion criteria. ChatGPT had a sensitivity of 95.7% in determining admission and a specificity of 18.2% in discharging patients. In 87.5% of cases, ChatGPT made the same primary diagnoses as physicians, with more accurate terminology use (42.9% vs. 21.4%, p = 0.02) and more comprehensive diagnostic lists (median number of diagnoses: 3 vs. 2, p < 0.001). Emergency Severity Index scores calculated by ChatGPT were not associated with admission (p = 0.12), hospital stay length (p = 0.91) or ICU admission (p = 0.54). Despite shorter mean word count (169 ± 66 vs. 272 ± 105, p < 0.001), ChatGPT was more likely to give additional treatment recommendations than physicians (94.3% vs. 73.5%, p < 0.001). Conclusions: Our hypothesis-generating data demonstrated that ChatGPT is associated with a high sensitivity in determining the admission of patients with metastatic prostate cancer in the emergency room. It also provides accurate and comprehensive diagnoses. These findings suggest that ChatGPT has the potential to assist health providers in improving patient triage in emergency settings, and may enhance both efficiency and quality of care provided by the physicians.

Background Both germline and somatic BReast CAncer gene (BRCA) mutations are poor prognostic markers in men with localized or metastatic prostate cancer. For instance, men with these mutations often are diagnosed with prostate cancer earlier and develop metastatic disease earlier compared with those who do not harbor similar mutations. Patients with germline alterations typically have more advanced disease and shorter overall survival (Castro E, Goh C, Olmos D, et al. Germline BRCA mutations are associated with higher risk of nodal involvement, distant metastasis, and poor survival outcomes in prostate cancer. J Clin Oncol. 2013;31(14):1748-1757. doi:10.1200/JCO.2012.43.1882). The risk of disease progression to metastatic disease is significant in patients with this genotype of prostate cancer. The percentage of patients free from metastatic disease was 90%, 72%, and 50%, respectively, compared with 97%, 94%, and 84% at 3, 5, and 10 years for patients with intact DNA repair (P < .001) (Castro E, Goh C, Leongamornlert D, et al. Effect of BRCA mutations on metastatic relapse and cause-specific survival after radical treatment for localised prostate cancer. Eur Urol. 2015;68(2):186-193. doi: 10.1016/j.eururo.2014.10.022). DNA damage repair non-BRCA mutations include alterations in genes such as ATM, CHEK2, PALB2, and RAD51. While less common than BRCA mutations, they have emerged as significant prognostic markers in prostate cancer. These BRCAness mutations are associated with a higher risk of aggressive disease and poorer survival outcomes. Given the debilitating physical and psychological side effects of androgen deprivation therapy (ADT) in relatively younger men with prostate cancer, delaying ADT in these men may be an attractive strategy. Given the proven efficacy of polyadenosine diphosphate-ribose polymerase (PARP) inhibitors in the castration-resistant prostate cancersetting, PARP inhibitor monotherapy in a nonmetastatic castration-sensitive (nmCSPC) setting has the potential to delay metastasis and delay the onset of ADT related symptoms. Methods This is a single-arm, single-center, open-label, phase II trial to assess the efficacy of rucaparib in patients with high-risk biochemically recurrent (BCR) nmHSPC, which was defined as PSA doubling time of <9 months, demonstrating a “BRCAness” genotype (BRCA1/2 and other homologous recombination repair mutations). A total of 15 patients were intended to be enrolled, with an expected enrollment duration of 12 months. Patients were given rucaparib 600 mg orally twice daily and were allowed to remain on study treatment until PSA progression defined by Prostate Cancer Working Group 3, with 2 years of follow-up after study treatment. We anticipated a total of 2-3 years until completion of the clinical trial. The primary endpoint was to assess the PSA progression-free survival (PSA-PFS). The secondary endpoints of the study were safety, the proportion of patients with a PSA 50% response (PSA 50), and an undetectable PSA. A 4-week treatment duration comprised one cycle. Results The study started enrolling in June 2019 and was prematurely terminated in June 2022 after the accrual of 7 patients because of changing standard of care treatments with the introduction of next-generation scans, eg, prostate-specific membrane antigen positron emission tomography (PSMA-PET). Seven patients were enrolled in the study with the following pathogenic alterations: ATM (n = 3), BRCA2 (n = 2), BRCA1 (n = 1), BRIP1 (n = 1), and RAD51 (n = 1). The median duration of follow-up was 18 months. A median of 20 cycles (range 4-42) was completed, median PSA-PFS was 35.37 months (95% CI, 0-85.11 months). In total, 2 patients achieved PSA50; both also achieved nadir PSA as undetectable. Grade ≥ 3 adverse events (AEs) were anemia and rash (in 1 patient each). No dose-limiting toxicities or severe AEs were seen. Conclusion Rucaparib demonstrated acceptable toxicity and efficacy signal as an ADT-sparing approach in patients with biochemically recurrent nonmetastatic prostate cancer. It is currently challenging to understand the optimal value of systemic therapy in this disease setting due to the rapidly changing standard of care. Additionally, there are relatively few patients with BRCAness who present with nonmetastatic hormone-sensitive prostate cancer (ClinicalTrials.gov Identifier: NCT03533946). This article reports clinical trial results of a phase II trial assessing the efficacy of rucaparib in patients with high-risk biochemically recurrent nonmetastatic hormone-sensitive prostate cancer.

Idiopathic granulomatous mastitis (IGM) is a chronic inflammatory disease of the breast, the etiology of which, has still not been elucidated. There have been several mechanisms proposed to explain the pathogenesis. Since the first description of the disease, it has proved itself to be a great diagnostic and therapeutic challenge. It is very often misdiagnosed as cancer, resulting in myriad workup by the physician and great distress to the patient. Clear guidelines as to the management have still not been described. Here, we describe two patients who presented with IGM and have been successfully treated. The first patient was treated with a combination of steroids and antibiotics. The second patient achieved remission of the disease with antibiotics alone. We also propose an algorithm for the management of IGM.

Metastatic urinary tract cancer (mUTC) is challenging to treat in older adults due to comorbidities. We compared the clinical courses of younger and older (≥70 years) adults with mUTC receiving first-line (1L) systemic therapy in a tertiary cancer center. Baseline clinical characteristics, treatments received, tolerability, and survival outcomes were analyzed. Among 212 patients (103 older vs. 109 younger), the older patients had lower hemoglobin at baseline (84% vs. 71%, p = 0.03), the majority were cisplatin-ineligible (74% vs. 45%, p < 0.001), received more immunotherapy-based treatments in the 1L (52% vs. 36%, p = 0.01), received fewer subsequent lines of treatment (median 0 vs. 1, p = 0.003), and had lower clinical trial participation (30% vs. 18%, p = 0.05) compared to the younger patients. When treated with 1L chemotherapy, older patients required more dose adjustments (53.4% vs. 23%, p = 0.001) and received fewer cycles of chemotherapy (median 4 vs. 5, p= 0.01). Older patients had similar OS (11.2 months vs. 14 months, p = 0.06) and similar rates of treatment-related severe toxicity and healthcare visits, independent of the type of systemic treatment received, compared to younger patients. We conclude that select older adults with mUTC can be safely treated with immunotherapy and risk-adjusted regimens of chemotherapy with tangible survival benefits.

Meningiomas are primary CNS tumors that arise from the arachnoid layer of the meninges. Genomic sequencing has revealed that NF2 mutations are the most common genetic alteration seen in meningiomas. Meningiomas although usually low grade, can sometimes progress to high grade. A patient who had several recurrences of meningiomas since childhood presented with recurrent headaches. Imaging showed that he had another recurrence of a meningioma. He underwent surgery for resection of the meningioma and histopathology showed NF2 mutation. He was started on everolimus and bevacizumab with good effect. Studies have shown that NF-2 mutated meningiomas have a good response to everolimus and bevacizumab with increased progression-free survival time and progression-free survival time at 6 months.

Ipilimumab with nivolumab (Ipi + Nivo) and immune checkpoint inhibitors with tyrosine kinase inhibitors (ICI + TKI) are the first-line approved treatments for intermediate- and poor-risk metastatic clear cell renal cell carcinoma (mccRCC); however, they have not been compared head-to-head in prospective trials to guide treatment selection. Thereupon, we sought to compare survival outcomes of patients receiving first-line Ipi + Nivo versus ICI + TKI, using a large, real-world database among patients with intermediate- and poor-risk mccRCC. This retrospective cohort study used a nationwide electronic health record-derived deidentified database, where patients with mccRCC with intermediate- or poor-risk who received first-line Ipi + Nivo or ICI + TKI between 20 June, 2016, and 26 January, 2023, were included. Primary outcomes were real-world time to next therapy (rwTTNT) and real-world overall survival (rwOS), summarized via Kaplan-Meier survival estimates with 95% confidence intervals (CIs) and compared in the context of propensity score (PS) matching weighted analysis. Of the 12,707 patients in the dataset, 1,438 with mccRCC met eligibility and were included. After PS matching weighted analysis, no significant difference in rwOS was noted between both groups (HR 1.01, 95% CI 0.86–1.19; p = 0.91); however, rwTTNT was significantly shorter with Ipi + Nivo than with ICI + TKI (HR 0.78, 95% CI 0.68–0.89; p < 0.001). In this large real-world study, there was evidence that rwOS was comparable, while rwTTNT was superior in patients receiving ICI + TKI compared to those receiving Ipi + Nivo. These real-world data offer important guidance for clinicians in choosing between Ipi + Nivo and ICI + TKI as frontline treatment.

Levamisole is a common contaminant in cocaine and has led to the emergence of an entity known as levamisole-induced vasculitis (LIV). There is no consensus on the management of this condition. We describe a patient who presented with acute on chronic LIV who was treated with pulse dose steroids. We aim to discuss the diagnosis and current management options for LIV. We have compared seven case reports that have measured C-reactive protein (CRP) and compared the CRP levels, site involved, dose, and mode of steroid administration. We postulate that elevated CRP may warrant steroid therapy over conservative management and could lead to a possible decreased hospital stay.

Background and objectives: Intermittent androgen deprivation therapy (iADT) may result in measurable improvements in quality of life over continuous ADT in patients with advanced prostate cancer (aPC). Here, we studied time to castration and testosterone recovery in real-world patients with aPC undergoing iADT with relugolix. Methods and design: Eligibility criteria for this retrospective study were histologically confirmed through the diagnosis of aPC and initiation of iADT with relugolix. Primary endpoints were time to castrate level of testosterone after relugolix initiation and time to recovery to noncastrate levels after relugolix discontinuation. Results: Overall, 25 patients with aPC were treated with iADT and with relugolix. Median time to serum testosterone <50 ng/dL was 1.13 months [range 0.67–2.5 months]. The median time to recovery >50 ng/dL was 1.4 months [range 0.83–6.57 months] from holding treatment with relugolix. Conclusion: iADT with relugolix is associated with a rapid time to testosterone suppression and recovery. These results may guide patients’ counseling and monitoring of serum testosterone and PSA levels in patients wishing to pursue iADT for aPC.

Cervical cancer is the fourth most common cancer in females. Clear cell adenocarcinoma of the cervix is an uncommon histological variant and is usually seen with intrauterine exposure to diethylstilbestrol. A 28-year-old female with no intrauterine exposure to diethylstilbestrol presented with postcoital bleeding. A pelvic exam revealed a cervical mass. Imaging confirmed the cervical mass and positron emission tomography scan showed an increased uptake in the cervical mass as well as the para-aortic and pelvic lymph nodes. Biopsy showed a clear cell carcinoma of the cervix. She was treated with cisplatin and paclitaxel for eight cycles and concurrent radiation therapy. She had a complete response to therapy and has been in complete remission nine months from the end of therapy. There are no clear guidelines for the treatment of clear cell carcinoma with current therapy based on the treatment of squamous and non-clear cell adenocarcinoma. Cisplatin and paclitaxel could be an option, given the successful treatment of the patient in our case.
