Consensus statement and clinical pathway for the management of colon cancer with peritoneal metastases in the state of Delaware
2023
Background: Increasing data suggests that the combination of modern systemic therapies and Cytoreductive surgery with or without Hyperthermic Intraperitoneal Chemotherapy (HIPEC) may improve the outcome of patients with colon cancer with peritoneal metastases. Patient selection and sequence of treatments remains ill-defined.
Materials and methods: A working group, the State of Delaware Peritoneal Surface Malignancies Task Force (DE-PSM-TF), was created including representatives from medical and surgical oncology from the acute care hospitals in Delaware. An extensive review of all available literature was carried out. Virtual meetings were held, and interpretation and discussion of the data was conducted.

Adjuvant Chemoradiotherapy in Resected Pancreatic Ductal Adenocarcinoma: Where Does the Benefit Lie? A Nomogram for Risk Stratification and Patient Selection
2022
Introduction: The impact of adjuvant sequential chemoradiotherapy (CRT) on survival in resected pancreatic ductal adenocarcinoma (PDAC) remains unclear and warrants further investigation.
Methods: NCDB patients with R0/R1 resected PDAC who received adjuvant chemotherapy without CRT or followed by CRT per RTOG-0848 protocol were included. Cox regression for 5-year overall survival (OS) was performed and used to construct a pathologic nomogram in patients who did not receive CRT. A risk score was calculated and patients were divided into low-risk and high-risk groups. Patients from each risk stratum were matched for the receipt of CRT to assess the added benefit of CRT on survival. The Kaplan-Meier analysis was performed to compare OS.

Adrenal biopsy, as a diagnostic method, is associated with decreased overall survival in patients with T1/T2 adrenocortical carcinoma: A propensity score-matched analysis
2021
Introduction: The standard diagnosis for adrenocortical carcinoma (ACC) is clinical diagnosis (CD) based on radiographic and biochemical studies. Biopsy diagnosis (BD) is seldom required for the suspicion of secondary malignancy. We aim to study the impact of BD in the context of underlying T1/T2 ACC on overall survival (OS) compared with CD.
Methods: National Cancer Database (NCDB) for endocrine malignancies was utilized. Only patients with non-metastatic ACC, whose method of diagnosis and local disease extension were reported, and received a surgical adrenalectomy with curative intent were included. Patients were divided by disease stage into T1/T2, T3, and T4 groups. A propensity score match was applied to those with T1/T2 disease who received CD versus BD and the Kaplan-Meier method was used to compare OS.

Surgical Management of the Axilla of HER2+ Breast Cancer in the Z1071 Era: A Propensity-Score-Matched Analysis of the NCDB
2021
Introduction: We aim to analyze survival outcomes for sentinel lymph node biopsy (SLNB) versus axillary lymph node dissection (ALND) in human epidermal growth factor receptor (HER2)+ infiltrative ductal carcinoma (IDC) that demonstrate complete clinical response (cCR) to neoadjuvant systemic therapy (NAST) after initial presentation with clinical N1 (cN1) disease.
Methods: NCDB 2004-2017 was utilized for the analysis. Female patients with unilateral HER2+ IDC, stage cT1-T4 cN1, who demonstrated cCR to NAST with reported definitive axillary surgical management were included. Patients were propensity score matched, and overall survival (OS) was compared. Cox regression analysis was used to identify survival predictors.

Patient Risk Subgroups Predict Benefit of Adjuvant Chemotherapy in Stage II Rectal Cancer Patients Following Neoadjuvant Chemoradiation and Total Mesorectal Excision
2021
Background: The benefit of adjuvant chemotherapy (AC) is unclear in stage II (cT3-T4 N0) rectal adenocarcinoma (RAC) after neoadjuvant chemoradiation (NCRT) and total mesorectal excision (TME). We aim to identify pathologic factors that influence overall survival (OS) and stratify patients into risk profiles to assess the AC benefit within each profile.
Patients and methods: The National Cancer Database for rectal cancer was utilized to identify patients with stage II RAC who completed NCRT and TME. Cox multivariable analysis was used to identify pathologic predictors of 5-year OS, which were then used to construct a nomogram and stratify patients into low-, intermediate-, and high-risk subgroups. Propensity score matching was applied for the receipt of AC within each risk stratum, and Kaplan-Meier analysis was used to measure 5-year OS.
