Background:Patients with type II diabetes mellitus (DM) have an increased risk of adenomatous colorectal (CRC) polyps and CRC cancer. The use of the anti-hyperglycemic agent metformin is associated with a reduced incidence of cancer-related deaths.Methods:We retrospectively evaluated the medical records of 4758 patients seen at a single institution and determined that 424 patients were identified by their physicians as having type II DM and CRC cancer. Data were subsequently acquired determining the subject's age, body mass index (BMI), and disease date of diagnosis, stage, site of cancer, treatment, and survival.Results:Patients with type II DM and CRC cancer treated with metformin as one of their diabetic medications had a survival of 76.9 months (95% CI=61.4–102.4) as compared with 56.9 months in those patients not treated with metformin (95% CI=44.8–68.8), P=0.048. By using a multivariable Cox regression model adjusted for age, sex, race, BMI, and initial stage of disease, we demonstrated that type II diabetic patients treated with metformin had a 30% improvement in overall survival (OS) when compared with diabetic patients treated with other diabetic agents.Conclusion:Colorectal cancer patients with DM treated with metformin as part of their diabetic therapy appear to have a superior OS.

Patients with sarcomatoid renal cell carcinoma have poor overall survival because of the aggressive biological behavior. Survival is longer for patients presenting with clinically localized disease, single metastatic site, and exhibiting a partial response to systemic therapy.

screening of patients with newly diagnosed cancer for hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV is not routine in oncology practice, and experts disagree about whether universal screening should be performed. OBJECTIVE To estimate the prevalence of HBV, HCV, and HIV infection among persons with newly diagnosed cancer. DESIGN, SETTING, AND PARTICIPANTS Multicenter prospective cohort study of patients with newly diagnosed cancer (ie, identified within 120 days of cancer diagnosis) at 9 academic and 9 community oncology institutions affiliated with SWOG (formerly the Southwest Oncology Group) Cancer Research Network, a member of the National Clinical Trials Network, with enrollment from August 29, 2013, through February 15, 2017. The data analysis was conducted using data available through August 17, 2017. MAIN OUTCOMES AND MEASURES The accrual goal was 3000 patients and the primary end point was the presence of HBV infection (previous or chronic), HCV infection, or HIV infection at enrollment. Patients with previous knowledge of infection as well as patients with unknown viral viral status were evaluated. RESULTS Of 3092 registered patients, 3051 were eligible and evaluable. Median (range) age was 60.6 (18.2-93.7) years, 1842 (60.4%) were female, 553 (18.1%) were black, and 558 (18.3%) were Hispanic ethnicity. Screened patients had similar clinical and demographic characteristics compared with those registered. The observed infection rate for previous HBV infection was 6.5% (95% CI, 5.6%-7.4%; n = 197 of 3050 patients); chronic HBV, 0.6% (95% CI, 0.4%-1.0%; n = 19 of 3050 patients); HCV, 2.4% (95% CI, 1.9%-3.0%; n = 71 of 2990 patients); and HIV, 1.1% (95% CI, 0.8%-1.6%; n = 34 of 3045). Among those with viral infections, 8 patients with chronic HBV (42.1%; 95% CI, 20.3%-66.5%), 22 patients with HCV (31.0%; 95% CI, 20.5%-43.1%), and 2 patients with HIV (5.9%; 95% CI, 0.7%-19.7%) were newly diagnosed through the study. Among patients with infections, 4 patients with chronic HBV (21.1%; 95% CI, 6.1%-45.6%), 23 patients with HCV (32.4%; 95% CI, 21.8%-44.5%), and 7 patients with HIV (20.6%; 95% CI, 8.7%-37.9%) had no identifiable risk factors. CONCLUSIONS AND RELEVANCE Results of this study found that a substantial proportion of patients with newly diagnosed cancer and concurrent HBV or HCV are unaware of their viral infection at the time of cancer diagnosis, and many had no identifiable risk factors for infection. Screening patients with cancer to identify HBV and HCV infection before starting treatment may be warranted to prevent viral reactivation and adverse clinical outcomes. The low rate of undiagnosed HIV infection may not support universal screening of newly diagnosed cancer patients.

In response to the COVID-19 social distancing guidelines, residency and fellowship programs transitioned to virtual instruction to deliver didactics and continue with medical education. The efficacy of such a fully online learning environment, however, remains unknown. To investigate its impact on medical education, this study surveyed hematology/oncology fellows at The University of Texas MD Anderson Cancer Center on their attitudes regarding the online-based lecture program. Fellows were emailed a 19-question survey with questions on demographics, ease of technical access to the online platform, level of comfort with participation, knowledge acquisition, wellness, and COVID-19-specific coverage. A free-text question soliciting ways to improve upon online learning was also included. The response rate was 71% (30/42). Most respondents reported easy/very easy accessibility to the online environment. Seventy-seven percent of the participants did not experience a technical issue. Seventy percent felt comfortable/very comfortable with participating in the conference. Thirty-seven percent felt comfortable/very comfortable with actively offering an answer to questions during the interactive board review session. Eighty-seven percent would have been more willing to offer an answer during the board review session if an anonymous poll format was utilized. Sixty-three percent felt they learned the same amount as they typically do during an in-person session. Thirty-three percent reported they were less focused as compared with an in-person session. One hundred percent of the participants had their questions answered, either at all times (87%) or sometimes (13%). Sixty percent experienced a change in social interactions as compared with an inperson session. Fifty-four percent reported that it was easy/very to balance online attendance despite personal/family commitments. One hundred percent appreciated the flexibility of the online learning environment. Ninety percent felt safer at home attending these lectures compared with receiving these lectures in-person during the COVID-19 pandemic. Overall, most fellows felt comfortable with the transition to a fully online learning environment. Strategies to encourage active participation, enhance social interaction, and provide additional flexibility are still needed.
