Introduction: Patients with non-small-cell lung cancer (NSCLC) who have never smoked or have tumors with mutations in EGFR generally derive minimal benefit from single-agent PD-1/PD-L1 checkpoint inhibitors. Prior data indicate that adding PD-L1 inhibition to anti-VEGF and cytotoxic chemotherapy may be a promising approach to overcoming immunotherapy resistance in these patients, however prospective validation is needed. This trial in progress (NCT03786692) is evaluating patients with stage IV NSCLC who have never smoked or who have tumors with sensitizing EGFR alterations to determine if a 4-drug combination of atezolizumab, carboplatin, pemetrexed, and bevacizumab can improve outcomes compared to carboplatin, pemetrexed and bevacizumab without atezolizumab.

Objective: To evaluate the association between irAEs and atezolizumab efficacy in patients with advanced non-small cell lung cancer (NSCLC) using pooled data from 3 phase 3 ICI studies.
Design, Setting, And Participants: IMpower130, IMpower132, and IMpower150 were phase 3, multicenter, open-label, randomized clinical trials to evaluate the efficacy and safety of chemoimmunotherapy combinations involving atezolizumab.
Background: In locally advanced rectal cancer treatment, neoadjuvant concurrent chemoradiation therapy (cCRT) is the standard of care. The tumor microenvironment (TME) is a complex entity comprising of tumor cells, immune cells and surrounding stroma and is closely associated with tumor growth and survival, response to antitumor therapies and also resistance to treatment. We aimed to assess the change in biomarkers associated with TME following standard neoadjuvant cCRT in rectal cancer.

FPs side effects are caused mainly by a lack of dihydropyrimidine dehydrogenase (DPD) enzyme. It has been noticed that treatment with infusional regimens of 5-FU is associated with more adverse events (AE) compared to bolus forms.

Methods: Overall, 1202 patients (intention-to-treat population) with chemotherapy-naive, metastatic, nonsquamous NSCLC were randomized to ABCP, ACP, or BCP. Patients with treated, stable brain metastases were permitted.
Introduction: We report the final overall survival (OS) analyses of atezolizumab-carboplatin-paclitaxel (ACP [experimental arm]) and OS data with approximately 39.8 months of median follow-up with atezolizumab-bevacizumab-carboplatin-paclitaxel (ABCP) versus bevacizumab-carboplatin-paclitaxel (BCP) in chemotherapy-naive patients with metastatic nonsquamous NSCLC in the phase 3 IMpower150 study (NCT02366143).
Methods: In this randomized, open-label study (N = 1202), coprimary end points included investigator-assessed progression-free survival and OS in intention-to-treat (ITT) wild-type (WT; no EGFR or ALK alterations) patients.
Immune checkpoint inhibitors (ICIs) in the recent times have transformed the landscape of the management of many solid tumors. Unfortunately, many immune-related adverse effects are associated with ICIs, which lead to a negative outcome in cancer treatment. We present a case of a 63-year-old female with metastatic adenocarcinoma of unknown origin, who developed celiac disease during the course of treatment with pembrolizumab.

Malignant cases of both pheochromocytomas and paragangliomas are even rarer, and currently there is no standard of care. This case report details the use of off-label immunotherapy and its efficacy in the management of the aforementioned tumor.
View Article and Find Full Text PDFBackground: The standard of care for non-metastatic squamous cell carcinoma of the anal canal (SCCA) is concurrent chemoradiotherapy. It is postulated that chemotherapy could be omitted for the earliest stages without worsening outcomes.
Methods: We queried the NCDB from 2004-2016 for patients with cT1N0M0 SCCA treated non-operatively with radiation, with and without chemotherapy, and at least two months of follow-up.
Background: Esophageal adenocarcinoma (EAC) is a deadly disease with limited treatment options. STING is a transmembrane protein that activates transcription of interferon genes, resulting in stimulation of APCs and enhanced CD8+ T-cell infiltration. The present study evaluates STING agonists, alone and in combination with radiation to determine durable anticancer activity in solid tumors.

Setting: We reviewed the outcomes of one of the largest data sets of patients with extrapulmonary small cell carcinomas (EPSCCs) identified at Allegheny General Hospital located in Pittsburgh, Pennsylvania, USA.
Participants: Patients diagnosed with grade 3 EPNECs were retrospectively identified.
Purpose This study was conducted to determine factors that influence palliative care (PC) consultation in patients receiving cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). Patient and methods We queried our Electronic Medical Record EPIC for a list of patients who underwent cytoreductive surgery with HIPEC or hyperthermic intrathoracic chemotherapy (HITEC) in the hospital from April 2016-April 2019. Data was manually extracted and patients who did not meet our criteria were excluded.
View Article and Find Full Text PDFPurpose: Large cell neuroendocrine carcinoma (LCNEC) is a rare pulmonary malignancy with clinicopathologic features of both non-small cell lung cancer (NSCLC) and small-cell lung cancer (SCLC). Given the paucity of available data regarding LCNEC management, we queried the National Cancer Database (NCDB) to describe trends in management, identify predictors of treatment receipt, and compare outcomes in patients receiving chemotherapy (ChT) and chemoradiotherapy (CRT).
Methods: We identified patients with locally advanced (Stage III) LCNEC of the lung treated with definitive ChT or CRT between the years of 2004-2015.
Background: Standard of care for locally advanced rectal cancer (LARC) (stage II/III) includes preoperative chemoradiation (CRT) followed by resection and adjuvant chemotherapy. Total neoadjuvant therapy (TNT) is a new treatment paradigm that delivers systemic therapy prior to CRT aimed at improving outcomes for high-risk patients. Here we analyzed the national cancer database (NCDB) comparing short-term post-operative outcomes between patients receiving TNT and CRT.

This study of a large, contemporary national database illustrates incidences of, and risk factors for, post-procedural mortality, prolonged hospital stay, and 30-day readmission.
Methods: From the National Cancer Database (NCDB), stage I-III pancreatic adenocarcinomas were identified [2004-2015].
Background: Surgery is the standard of care for early stage non-small cell lung cancer (NSCLC). Stereotactic body radiotherapy (SBRT) is another definitive treatment option for those patients who have not been treated surgically. Comparison of approaches is being explored in NSCLC, but has yet to be compared exclusively in large cell neuroendocrine carcinoma (LCNEC) of the lung.
View Article and Find Full Text PDFBackground: Adjuvant radiation is generally not recommended for colon cancer but may be considered in certain clinical scenarios [advanced local disease (pT4) and/or positive margins]. Guidelines in this area are lacking; thus we analyzed the National Cancer Database (NCDB) for patterns of care in this regard and any predictors for outcome.
Methods: We queried the NCDB from 2004 to 2016 for patients with resected adenocarcinoma of the colon having pT4 and/or had positive margins on final pathology and who received adjuvant multiagent chemotherapy.
Background: Neoadjuvant chemoradiotherapy (nCRT) followed by resection and postoperative multi-agent chemotherapy (maChT) is the standard of care for locally advanced rectal cancer. Using this approach, maChT administration can be delayed for several months, leading to concern for distant metastases. To counteract this, a novel treatment approach known as total neoadjuvant therapy (TNT) has gained popularity, in which patients receive both maChT and nCRT prior to resection.
View Article and Find Full Text PDFBackground: Response of pancreatic adenocarcinoma to neoadjuvant chemotherapy (nCT) or chemoradiotherapy (nCRT) may be associated with prognosis, but long-term outcomes based on response to neoadjuvant therapy have not been well evaluated to date.
Methods: The National Cancer Database was queried for patients with pancreatic adenocarcinoma receiving nCT/nCRT. To evaluate response to nCT/nCRT, comparisons were made from cT and cN stage to the respective post-neoadjuvant therapy ypT and ypN stages.
Background: Surgery remains the standard of care in rectal cancer. Select patients will not undergo surgery for reasons such as medical inoperability or a watch-and-wait approach and instead are managed with definitive chemoradiation.
Objective: We used the National Cancer Database to identify overall survival and predictors thereof in the nonoperative management of patients with rectal cancer.
Objectives: The appropriate timing of chemotherapy following surgery for resectable pancreatic adenocarcinoma is controversial. Using the National Cancer Database we evaluated time to initiation of chemotherapy postresection and correlated with outcome.
Methods: We identified stage I-III pancreatic adenocarcinoma treated surgically with adjuvant chemoradiotherapy.
Importance: Primary Adenocarcinoma of the anus is a rare disease with a poor prognosis and thus tends to have a more aggressive treatment algorithm, typically involving a surgical approach. Prior to 2001, a few retrospective studies outlined improved outcomes with the incorporation of surgery with chemoradiation. However, since the publication of these studies, advancement in radiotherapy modalities and imaging have left the question of improved outcomes while reserving surgery for salvage.
