Shifting Sociodemographic Characteristics of a Phase I Clinical Trial Population at an NCI-Designated Comprehensive Cancer Center in the Southeast.

Racial and ethnic minority populations are consistently under-represented in oncology clinical trials despite comprising a disproportionate share of a cancer burden. Phase I oncology clinical trials pose a unique challenge and opportunity for minority inclusion. Here we compared the sociodemographic characteristics of patients participating in phase 1 clinical trials a National Cancer Institute ( NCI)-designated comprehensive center to all patients at the center, patients with new cancer diagnosis in metropolitan Atlanta and patients with new cancer diagnoses in the state of Georgia. From 2015 to 2020, 2325 patients (43.4% female, 56.6% male) consented to participate in a phase I trial. Grouped self-reported race distribution was 70.3% White, 26.2% Black, and 3.5% other. Of new patient registrations at Winship Cancer Institute (N = 107 497) (50% F, 50% M), grouped race distribution was 63.3% White, 32.0% Black, and 4.7% other. Patients with new cancer diagnoses in metro Atlanta from 2015 to 2016 (N = 31101) were 58.4% White, 37.2% Black, and 4.3% other. Race and sex distribution of phase I patients was significantly different than Winship patients (P < .001). Over time, percent of White patients decreased in both phase I and Winship groups (P = .009 and P < .001, respectively); percentage of females did not change in either group (P = .54 phase I, P = .063 Winship). Although phase I patients were more likely to be White, male, and privately ensured than the Winship cohort, from 2015 to 2020 the percentage of White patients in phase I trials and among all new patients treated at Winship decreased. The intent of characterizing existing disparities is to improve the representation of patients from racial and ethnic minority backgrounds in phase I clinical trials.

Posttraumatic stress disorder and breast cancer: Risk factors and the role of inflammation and endocrine function.

A breast cancer diagnosis can be a life-changing and stressful experience that can lead to chronic mental health conditions such as posttraumatic stress disorder (PTSD). Greater than one-third of patients initially diagnosed with PTSD after a diagnosis of breast cancer continue to have persistent or worsening PTSD symptoms after 4 years. An emerging body of literature has indicated several key environmental and biological risk factors for PTSD among survivors of breast cancer. Well-recognized risk factors include having a history of childhood trauma, being nonwhite, obesity, younger age at the time of diagnosis, diagnosis with a higher stage of breast cancer, and short time since treatment. Of the emerging risk factors related to fear circuitry in the brain, 2 pathways of particular importance are the stress-driven activation of inflammatory pathways and the long-term effect of antiendocrine therapies. These central and peripheral responses during and after stress exposure are important because increased fear and anxiety can lead to the maintenance of PTSD and worse patient outcomes. Given the poor outcomes associated with PTSD and the high prevalence of breast cancer in women, more research to identify those women at heightened risk of PTSD after breast cancer is warranted to reduce the number of diagnoses and lessen the negative impact of this chronic mental health condition.

The Quest to Eradicate HPV-Related Oropharyngeal Carcinoma: An Opportunity Not to Miss.

Oropharyngeal squamous cell carcinoma (OPSCC) accounts for more than half of all head and neck cancers. Since the 1970s, OPSCC has shifted from an environmentally triggered to virally mediated disease due to a sharp rise in human papillomavirus (HPV)-related squamous cell carcinoma. Although a highly effective prophylactic vaccine is available, its current implementation is far below national targets, and OPSCC incidence is predicted to further increase by 2045. However, we believe that with prompt action now, we can not only defy these predictions but also effectively eradicate HPV-related OPSCC in these next 20 years. We herein provide an overview of the necessary elements to eliminate this disease: improved primary vaccine uptake, a 1-time universal vaccination effort, and implementation of novel therapeutics that have potential to cure existing disease.

Neoadjuvant treatment of pancreatic carcinosarcoma: a case report and review of literature.

Carcinosarcoma of the pancreas is a rare malignancy with high mortality. Diagnosis is based on pathologic demonstration of adjacent malignant epithelial and mesenchymal tissue. Due to inherent limitations of biopsy sampling, tumor heterogeneity is rarely recognized until definitive surgical resection. A 52-year-old woman presented to the emergency department with diarrhea. Abdominal CT imaging showed a 4.1×4.5 cm mass in the head of the pancreas with intrahepatic and extrahepatic ductal dilation. Endoscopic ultrasound (EUS) confirmed the mass with evidence of superior mesenteric vein involvement. Fine-needle aspiration (FNA) showed adenocarcinoma. After multi-disciplinary tumor board discussion, the patient was treated with four cycles of neoadjuvant of oxaliplatin, irinotecan, fluorouracil, and leucovorin (FOLFIRINOX) followed by 50-55 Gray (Gy) photon radiation with concurrent capecitabine. Pancreaticoduodenectomy was performed after 6 months of neoadjuvant therapy. Pathologic examination revealed carcinosarcoma of the pancreas, with pathological partial response in the resected tumor. Patient has been disease-free for 15 months. Carcinosarcoma of pancreas is a rare clinical entity. There is no established systemic therapy and only two patients, inclusive of this case, have been treated with neoadjuvant chemotherapy. Here we report a case of pancreatic carcinosarcoma treated with neoadjuvant FOLFIRINOX followed by chemoradiation with pathological partial response. Modern treatment approaches for pancreatic ductal adenocarcinoma (PDAC) could be applied to this rare pathology.

Sex Differences in Peritraumatic Inflammatory Cytokines and Steroid Hormones Contribute to Prospective Risk for Nonremitting Posttraumatic Stress Disorder.

Women are at higher risk for developing posttraumatic stress disorder (PTSD) compared to men, yet little is known about the biological contributors to this sex difference. One possible mechanism is differential immunological and neuroendocrine responses to traumatic stress exposure. In the current prospective study, we aimed to identify whether sex is indirectly associated with the probability of developing nonremitting PTSD through pro-inflammatory markers and whether steroid hormone concentrations influence this effect. Female (n = 179) and male (n = 197) trauma survivors were recruited from an emergency department and completed clinical assessment within 24 h and blood samples within ∼three hours of trauma exposure. Pro-inflammatory cytokines (IL-6, IL-1 ß , TNF, IFNγ), and steroid hormone (estradiol, testosterone, progesterone, cortisol) concentrations were quantified in plasma. Compared to men, women had a higher probability of developing nonremitting PTSD after trauma (p = 0.04), had lower pro-inflammatory cytokines and testosterone (p's<0.001), and had higher cortisol and progesterone (p's<0.001) concentrations. Estradiol concentrations were not different between the sexes (p = 0.24). Pro-inflammatory cytokines were a significant mediator in the relationship between sex and probability of developing nonremitting PTSD (p < 0.05), such that men had higher concentrations of pro-inflammatory cytokines which were associated with lower risk of nonremitting PTSD development. This effect was significantly moderated by estradiol (p < 0.05), as higher estradiol levels in men were associated with higher pro-inflammatory cytokine concentrations and lower risk for developing nonremitting PTSD. The current results suggest that sex differences in the pro-inflammatory cytokine response to trauma exposure partially mediate the probability of developing nonremitting PTSD, and that the protective ability to mount an pro-inflammatory cytokine response in men may depend on higher estradiol levels in the aftermath of trauma exposure.
