RESUMO
Introduction: Cancer-associated cachexia (CC) is a progressive syndrome characterized by unintentional weight loss, muscle atrophy, fatigue, and poor outcomes that affects most patients with pancreatic ductal adenocarcinoma (PDAC). The ability to identify and classify CC stage along its continuum early in the disease process is challenging but critical for management. Objectives: The main objective of this study was to determine the prevalence of CC stage overall and by sex and race and ethnicity among treatment-naïve PDAC cases using clinical, nutritional, and functional criteria. Secondary objectives included identifying the prevalence and predictors of higher symptom burden, supportive care needs, and quality of life (QoL), and examining their influence on overall survival (OS). Materials and methods: A population-based multi-institutional prospective cohort study of patients with PDAC was conducted between 2018 and 2021 by the Florida Pancreas Collaborative. Leveraging patient-reported data and laboratory values, participants were classified at baseline into four stages [non-cachexia (NCa), pre-cachexia (PCa), cachexia (Ca), and refractory cachexia (RCa)]. Multivariate regression, Kaplan Meier analyses, and Cox regression were conducted to evaluate associations. Results: CC stage was estimated for 309 PDAC cases (156 females, 153 males). The overall prevalence of NCa, PCa, Ca, and RCa was 12.9%, 24.6%, 54.1%, and 8.4%, respectively. CC prevalence across all CC stages was highest for males and racial and ethnic minorities. Criteria differentiated NCa cases from other groups, but did not distinguish PCa from Ca. The most frequently reported symptoms included weight loss, fatigue, pain, anxiety, and depression, with pain significantly worsening over time. The greatest supportive care needs included emotional and physical domains. Males, Black people, and those with RCa had the worst OS. Conclusions: Using clinical, nutritional, and functional criteria, nearly one-quarter of the PDAC cases in our diverse, multi-institutional cohort had PCa and 62.5% had Ca or RCa at the time of diagnosis. The PCa estimate is higher than that reported in prior studies. We recommend these criteria be used to aid in CC classification, monitoring, and management of all incident PDAC cases. Findings also highlight the recommendation for continued emotional support, assistance in alleviating pain, and supportive care needs throughout the PDAC treatment journey.
RESUMO
INTRODUCTION: Explored the diversity and inclusion of our annual meeting. The authors compared our members' diversity to the participation in the impactful portions of our annual conference as a measure of our organizational inclusion. METHODS: The authors retrospectively reviewed and calculated the diversity demographics of our membership based on our 2022 data. Demographics consisted of institutional affiliation and gender. Also the authors retrospectively analyzed the topics discussed at our annual meeting from 2010 to 2022. RESULTS: In 2022, the Association of Program Directors in Surgery (APDS) had 308 members; while we had 100% of the institutional affiliation, most members did not self-report gender or ethnicity information. One hundred eleven members self-reported gender information in 2022: 76% were men and 24% were women. Fifty-seven percent of our institutions had a medical school affiliation, 40% had a nonmedical school affiliation, and 3% had a military instillation affiliation. CONCLUSION: The authors' current analysis demonstrates disparities in the distribution of meaningful space in the APDS meeting program. Future efforts are ongoing to identify members and their demographics, track participation, and encourage more diverse involvement across membership.

Background: Well-annotated, high-quality biorepositories provide a valuable platform to support translational research. However, most biorepositories have poor representation of minority groups, limiting the ability to address health disparities. Methods: We describe the establishment of the Florida Pancreas Collaborative (FPC), the first state-wide prospective cohort study and biorepository designed to address the higher burden of pancreatic cancer (PaCa) in African Americans (AA) compared to Non-Hispanic Whites (NHW) and Hispanic/Latinx (H/L). We provide an overview of stakeholders; study eligibility and design; recruitment strategies; standard operating procedures to collect, process, store, and transfer biospecimens, medical images, and data; our cloud-based data management platform; and progress regarding recruitment and biobanking. Results: The FPC consists of multidisciplinary teams from fifteen Florida medical institutions. From March 2019 through August 2020, 350 patients were assessed for eligibility, 323 met inclusion/exclusion criteria, and 305 (94%) enrolled, including 228 NHW, 30 AA, and 47 H/L, with 94%, 100%, and 94% participation rates, respectively. A high percentage of participants have donated blood (87%), pancreatic tumor tissue (41%), computed tomography scans (76%), and questionnaires (62%). Conclusions: This biorepository addresses a critical gap in PaCa research and has potential to advance translational studies intended to minimize disparities and reduce PaCa-related morbidity and mortality.
RESUMO
Clinical trials have provided guidance in developing triggers for transfusing in the hemodynamically stable patient. These studies have identified that improved outcomes can be obtained in the massively transfused patient when platelets and fresh frozen plasma are transfused with packed red blood cells. Studies that characterize the complications of transfusions, such as transfusion-related acute lung injury and poor cancer-related outcomes, are discussed. Emerging data that characterize the risk factors associated with transfusion-related acute lung injury and suggest metastasis and local recurrence occur at a higher rate in the transfused patient are discussed. Hematologic disorders commonly encountered by surgeons are discussed.

BACKGROUND: Hepatocellular carcinomas (HCC) associated with inflammation that undergo radiofrequency ablation (RFA) appear to have poorer local control rates. Little is known of how mediators of inflammation influence HCC cellular thermotolerance, which in part is mediated by heat shock protein 70 (HSP70). This study determines how inflammatory mediators affect cellular thermotolerance and provides insight into how associated inflammation may impact HCC RFA local control rates. METHODS: HepG2 cell lines were cultured in control medium (CM) or CM containing conditioned medium of endotoxin-activated macrophage (CMM). Serial dilutions of CMM established microenvironments approximating low, medium, and high CMM. All groups underwent a heat shock challenge (HSC) at 45 degrees C for 10 min. Western blot, Northern blot, densitometric analysis, along with thymidine and clonogenic assays determined how inflammation influenced multiple biological endpoints. RESULTS: Cells cultured in low CMM expressed significantly more HSP70 RNA and protein compared with control cells after HSC. The cells also had a higher proliferative and survival rate after HSC compared with control cells. Medium CMM cultured cells had no significant difference in HSP70 RNA and protein production or proliferation and survival rates after HSC, compared with CM cultured cells. AT high CMM, the inhibitory effects of inflammatory mediators prevailed and all of the measured endpoints were significantly less compared with CM cultured cells. CONCLUSIONS: This study demonstrates that inflammation can alter the responsiveness of HCC cells to a HSC in a dose-dependent manner. This study supports the clinical observation that HCC associated with chronic inflammation have worse RFA local control rates.

CONTEXT: The incidence of esophageal adenocarcinoma is rising and has surpassed squamous cell carcinoma. OBJECTIVE: To determine how the increasing incidence of esophageal adenocarcinoma alters the classic clinical presentation and the implications of these changes for diagnosis. DESIGN AND SETTING: A five-year retrospective review (1991-1996) was made. PARTICIPANTS: All patients were identified by a computerized registry search with a diagnosis of esophageal carcinoma. MAIN OUTCOME MEASURES: Clinical presentation; duration of symptoms; and correlation with diagnosis, pathology, treatment and outcome. RESULTS: One-hundred-eight (35%) patients had squamous cell carcinoma and 199 (65%) had adenocarcinoma. Dysphagia and weight loss were more common among patients with squamous cell carcinoma (93% and 68%), when compared to adenocarcinoma (79% and 53%). Twenty-one percent of adenocarcinoma patients had other symptoms presentation, including gastroesophageal reflux disease. Once dysphagia was present, there was no correlation between the duration.of symptoms and survival. However, cancers detected in patients who presented with reflux symptoms without dysphagia showed an improved prognosis over patients who presented with both. CONCLUSIONS: Esophageal adenocarcinoma has surpassed squamous cell carcinoma. Gastroesophageal reflux was associated with an earlier stage of presentation compared to the "classic" presentation of esophageal cancer.

OBJECTIVE: To identify the incidence of parapharyngeal space (PPS) recurrences and how they impact survival in advanced-stage soft-palate carcinoma patients. STUDY DESIGN AND SETTING: One hundred thirty-seven patients' charts were reviewed from 1971 to 1996. Inclusion criteria were patients who received a per-oral resection, discontinuous neck dissection, and postoperative adjuvant radiation therapy; 15 patients met criteria for inclusion. The incidence of PPS recurrences, regional failure, and survival were endpoints that were analyzed. RESULTS: There were no local failures in our study. Regional failures excluding the PPS (levels I-V) were 27%, and 40% occurred within the PPS. Cervical adenopathy was associated with 83% of the PPS recurrences. Median survival for PPS recurrences was 26 months, compared with 67 months for levels I-V recurrences (n = ns). CONCLUSIONS: The incidence of PPS recurrences is substantial in advanced-stage soft-palate cancer. PPS recurrences negatively impact survival; without effective salvage techniques for these recurrences or effective adjuvant therapy, poor patient outcomes can be expected.

Growth of head and neck squamous cell carcinoma (HNSCC) is generally associated with an inflammatory component. It is hypothesized that these tumor cells develop mechanisms to evade the growth inhibitory effects of cytokines that are present in the tumor microenvironment. This study determined the changes in responsiveness to inflammatory cytokines that accompany the transition of normal to transformed epithelial cells. Paired primary cultures of normal epithelial cells (NEC) and SCC cells were established from 16 patients. Receptor-mediated activation of signal transducer and activator of transcription and extracellular signal-regulated kinase pathways in response to cytokine treatments was identified by immunoblot analysis. Thymidine incorporation determined the impact of the cytokines on DNA synthesis. HNNEC and HNSCC displayed a prominent signaling in response to oncostatin M, interleukin-6, IFN-gamma, and epidermal growth factor. Untreated HNSCC showed an elevated level of phosphorylated signal transducer and activator of transcription 3 and extracellular signal-regulated kinase (P < 0.001) compared with HNNEC, suggesting constitutively activated pathways. Moreover, HNSCC cells phosphorylated significantly more signal transducer and activator of transcription 1 in response to oncostatin M (P = 0.002) and IFN-gamma (P = 0.018) treatments. DNA synthesis of SCC cells was less inhibited by cytokines produced by endotoxin-stimulated macrophages (P = 0.016) than that of NEC. Low-dose oncostatin M slightly enhanced proliferation of SCC, whereas that of NEC was suppressed (P = 0.016). This study identified significant alterations in signal transduction pathways engaged by cytokines and which are associated with loss of growth inhibition of HNSCC. Increased signal transducer and activator of transcription phosphorylation, along with constitutively phosphorylated extracellular signal-regulated kinase in HNSCC, suggest that these pathways as molecular markers are important in the malignant transformation process and are potential targets for treatment.

We conducted a retrospective study of 13 patients with parathyroid carcinoma to assess their clinical characteristics and surgical outcomes. Study parameters included patient demographics, survival, treatment response, and recurrence. We found that all patients who had undergone local tumor excision developed a recurrence, compared with only 33% of those available for follow-up after en bloc tumor resection. Based on these findings, we recommend en bloc tumor resection as the initial treatment of choice for patients diagnosed with parathyroid carcinoma.

Simultaneous, synchronous, and metachronous presentation of lung malignancies when treating head and neck squamous cell cancers is one of the most difficult challenges in head and neck surgery. However, good (> 40%) 5-year survival can be obtained when proper screening techniques, patient selection, and therapy are combined. Because of the complexity of the head and neck resection and reconstruction and the multiple surgical and medical services used to diagnose and treat this clinical entity, a comprehensive review of the current literature is provided. The clinically pertinent meanings of simultaneous, synchronous, and metachronous second malignancy of the lung are presented. A review of the current literature is presented that divides second lung malignancy into two groups: second primary and metastasis. The incidence of a second lung malignancy is identified. The tools used in the screening of high-risk patients and the role of the new diagnostic studies such as positron emission tomography and positron emission tomography CT scans are reviewed. Finally, the current literature on patient selection and surgical therapy is used to put forth a clinical pathway followed at the authors' institution for the treatment of these patients.

BACKGROUND: Anaplastic thyroid cancer ranks among the most lethal of all human malignancies. Its rarity and rapidly fatal course have made it a difficult cancer to both study and treat. Unfortunately, there has been little progress in the management and control of this malignancy. Anaplastic transformation, or the intratumoral evolution of anaplastic carcinoma from pre-existing differentiated thyroid cancer, has become a well-accepted process, despite a limited understanding of its underlying mechanisms. METHODS: It is through review of the literature that an understanding of the aggressive disease biology can be developed. The aim of this review is to evaluate the relevant clinical, pathologic, and molecular studies to develop an insight into the mechanisms that underlie the intratumoral molecular evolution of anaplastic thyroid carcinoma. RESULTS/CONCLUSION: It is based on an understanding of this process that effective treatments for this aggressive malignancy are currently being developed.

BACKGROUND: The objective of this study was to describe the clinicopathologic manifestations of disease and outcomes of treatment among individuals without a history of smoking tobacco or consuming alcohol who develop head and neck cancer. METHODS: Of 1648 invasive head and neck cancer cases treated between 1970 and 2001 at Roswell Park Cancer Institute, 40 patients were identified as never having smoked tobacco or consumed alcohol during their lifetime. These cases were reviewed to gather data on multiple clinicopathologic variables. RESULTS: Mean age at presentation of nonsmoker/nondrinker head and neck cancer patients was 60 years (range, 27 to 90 years), and 78% (n = 31) of the patients were women. The distributions of tumor sites were 75.0% oral cavity (n = 30), 20.0% oropharynx (n = 8), and 5.0% larynx (n = 2). Sixteen patients (40%) experienced a recurrence of disease during the follow-up period, and 10 patients (25.0%) developed a second primary tumor a median of 6 years after their initial diagnosis. CONCLUSIONS: The nonsmoker/nondrinker head and neck cancer patient tends to be elderly and female, have oral cavity primary tumors, and be predisposed to second primary tumor development.
