Associations with other cancer-related biomarkers might contribute to poor outcomes in RAS-altered, younger patients with colorectal cancer.

Colorectal cancer (CRC) is a common cancer in younger adults. In patients undergoing liver resection with RAS-altered CRCs, there is evidence suggesting younger patients have worse outcomes than older patients. To explain this pattern, differences in associations between RAS status and other cancer-related biomarkers in tumors from younger versus older patients with CRC were evaluated in a cohort of 925 patients with CRC, 277 (30.

Methods for improving colorectal cancer annotation efficiency for artificial intelligence-observer training.

Background: Missing occult cancer lesions accounts for the most diagnostic errors in retrospective radiology reviews as early cancer can be small or subtle, making the lesions difficult to detect. Second-observer is the most effective technique for reducing these events and can be economically implemented with the advent of artificial intelligence (AI).

Aim: To achieve appropriate AI model training, a large annotated dataset is necessary to train the AI models.

Endoscopic Palliative Therapies for Esophageal Cancer.

Endoscopic palliation of dysphagia for patients with inoperable esophageal cancer is complex, highly dependent on local expertise, and best done in a multidisciplinary fashion. Systemic therapy is the standard of care because it has been shown to improve survival. Esophageal stenting has traditionally been the most used endoscopic modality.

Phase 1 study of the safety, pharmacokinetics, and preliminary efficacy of CA102N as monotherapy and in combination with trifluridine-tipiracil in patients with locally advanced or metastatic solid tumors.

CA102N is a covalently bound conjugate of modified nimesulide (Nim) and NaHA, the sodium salt of hyaluronic acid (HA). HA is a natural ligand of cluster of differentiation 44 (CD44), which is over-expressed in colorectal cancer (CRC). CA102N is designed to deliver nimesulide directly to the tumor via the interaction of HA and CD44.

American Radium Society (ARS) Appropriate Use Criteria (AUC) for Locoregional Gastric Adenocarcinoma: Systematic Review and Guidelines.

Objective: The objective of this study was to systematically evaluate the data regarding the use of neoadjuvant, perioperative, surgical, and adjuvant treatment options in localized gastric cancer patients and to develop Appropriate Use Criteria recommended by a panel of experts convened by the American Radium Society.

Methods: Preferred reporting items for systematic reviews and meta-analyses methodology was used to develop an extensive analysis of peer-reviewed phase 2/2R/3 trials, as well as meta-analyses found within the Ovid Medline database between 2010 and 2020. The expert panel then rated the appropriateness of various treatments in 5 representative clinical scenarios through a well-established consensus methodology (modified Delphi).

Infection Masquerading as Recurrence of Pancreatic Ductal Adenocarcinoma: A Cautionary Tale.

We present a case of a 59-year-old male undergoing adjuvant chemotherapy for his pancreatic adenocarcinoma post-surgical resection. He had an acute rise in carbohydrate antigen (CA) 19-9 level, which raised suspicion of metastatic disease. Instead, the patient was diagnosed to have a liver abscess, the treatment of which brought the CA 19-9 level back to normal.

Anti-angiogenesis Revisited: Combination with Immunotherapy in Solid Tumors.

Purpose Of Review: Both anti-angiogenesis and immunotherapy are well-established therapeutic options in solid tumors. Here, we review the rationale as well as clinical evidence of combining these two approaches.

Recent Findings: There is strong rationale and substantial preclinical and clinical evidence that anti-angiogenesis plays a pivotal role in overcoming immunotherapy resistance.

Skeletal metastases in advanced pancreatic ductal adenocarcinoma: a retrospective analysis.

Background: Skeletal metastases (SM) in advanced pancreatic ductal adenocarcinoma (PDAC) is an infrequent occurrence that has been previously reported in literature to occur in less than 2.5% of the cases. Complications such as pathological fractures can result in intractable pain, immobilization and a significant deterioration in quality of life.

When the Tumor Lyses: A Case Report on Spontaneous Tumor Lysis Syndrome.

Tumor lysis syndrome (TLS) is an oncological emergency characterized by severe electrolyte disturbance that typically occurs when hematologic cancer patients have been started on systemic chemotherapy. We present an uncommon case of spontaneous TLS (STLS) occurring in a patient with cholangiocarcinoma. The patient was a 59-year-old male with newly diagnosed differentiated carcinoma of unknown origin who presented with weakness, fatigue, and lightheadedness.

Randomized, double-blind, placebo-controlled phase II study of istiratumab (MM-141) plus nab-paclitaxel and gemcitabine versus nab-paclitaxel and gemcitabine in front-line metastatic pancreatic cancer (CARRIE).

Background: Preclinical data suggest that dual blockade of the insulin-like growth factor-1 receptor (IGF-1R) and HER3 pathways has superior activity to IGF-1R blockade alone in pancreatic ductal adenocarcinoma (PDAC). We tested whether istiratumab, an IGF-1R- and ErbB3-bispecific antibody, can enhance the efficacy of standard of care (SOC) chemotherapy in patients with metastatic PDAC selected for high IGF-1 serum levels.

Patients And Methods: CARRIE was an international, randomized, double-blind, placebo-controlled phase II study for patients with previously untreated metastatic PDAC.

Chemotherapy re-challenge response rate in metastatic colorectal cancer.

Background: There are few treatment options in metastatic colorectal cancer (mCRC) after progression on standard chemotherapy. Third and fourth line therapies typically consist of regorafenib or trifluridine-tipiracil, however, clinical benefit of these medications is limited, as progression free survival is approximately 1.9 months for regorafenib (Grothey 2013) and 2.

Liquid nitrogen spray cryotherapy for dysphagia palliation in patients with inoperable esophageal cancer.

Background And Aims: Dysphagia is a debilitating symptom in patients with inoperable esophageal cancer that contributes to poor quality of life and worsening nutritional status. The 2 most commonly used palliative modalities for dysphagia are radiation therapy and esophageal stent placement. However, radiation therapy is limited by adverse events (AEs) and total dose, and stent placement has a high rate of AEs, including reflux, migration, and chest pain.

Synchronous primary adenocarcinoma of the lung and pancreas: a case series and review of the literature.

Aim: The frequency of pancreatic cancer in association with cancer of other organs ranges from 1 to 20%, with the most common ones being gastric, colon, thyroid and genitourinary. The presence of synchronous lung and pancreatic cancers is extremely rare.

Case Series: Two patients with extensive smoking history and variable presentations were found to have simultaneous lung and pancreatic masses both lesions being different histologically and on immunohistochemical staining.

Comprehensive Genomic Profiling of Esthesioneuroblastoma Reveals Additional Treatment Options.

Background: Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, is a rare malignant neoplasm of the olfactory mucosa. Despite surgical resection combined with radiotherapy and adjuvant chemotherapy, ENB often relapses with rapid progression. Current multimodality, nontargeted therapy for relapsed ENB is of limited clinical benefit.

Novel Diagnostic and Predictive Biomarkers in Pancreatic Adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal disease for a multitude of reasons including very late diagnosis. This in part is due to the lack of understanding of the biological behavior of PDAC and the ineffective screening for this disease. Significant efforts have been dedicated to finding the appropriate serum and imaging biomarkers to help early detection and predict response to treatment of PDAC.

Platinum-Gemcitabine-Avastin (PGA) for platinum-resistant/refractory ovarian cancer.

Objectives: Synergism between gemcitabine and platinum is known clinically. Bevacizumab in combination with single-agent chemotherapy has demonstrated significant clinical activity in platinum-resistant recurrent ovarian cancer in AURELIA study. However, the efficacy of platinum-gemcitabine-bevacizumab (PGA) has not been investigated in the platinum-resistant population.

Signet-Ring Cell Carcinoma of the Colon: A Case Report and Review of the Literature.

Background: Colorectal adenocarcinoma (CRC) is the third leading cause of death in the United States. One of the histologic subtypes of CRC is signet-ring cell carcinoma (SRCC), which has a distinct molecular and tumor biology from that of adenocarcinoma. Primary SRCC diagnosed at an early stage is very rare as most cases are detected at an advanced stage.

Albumin-bound paclitaxel in solid tumors: clinical development and future directions.

Albumin-bound paclitaxel (nab-paclitaxel) is a solvent-free formulation of paclitaxel that was initially developed more than a decade ago to overcome toxicities associated with the solvents used in the formulation of standard paclitaxel and to potentially improve efficacy. Nab-paclitaxel has demonstrated an advantage over solvent-based paclitaxel by being able to deliver a higher dose of paclitaxel to tumors and decrease the incidence of serious toxicities, including severe allergic reactions. To date, nab-paclitaxel has been indicated for the treatment of three solid tumors in the USA.

Metastatic Breast Cancer with Extensive Osseous Metastasis Presenting with Symptomatic Immune Thrombocytopenic Purpura and Anemia: A Case Report and Review of the Literature.

Background: Immune thrombocytopenic purpura (ITP) is a rare acquired bleeding disorder with an estimated incidence of 1 in 10,000 people in the general population. The association of ITP with breast cancer is an even rarer entity with very limited reports in the English literature.

Case Presentation: We report a case of a 51-year-old female with no significant past medical history who presented with sudden onset of malaise, syncope, gingival bleed and epistaxis.

Promising new therapies in advanced pancreatic adenocarcinomas.

Pancreatic ductal adenocarcinoma is a lethal disease due to late diagnosis, early metastasis and the lack of effective therapies. In patients with metastatic disease, 1-year survival ranges from 17 to 23% and 5-year survival is less than 5%. This necessitates an urgent need for developing more effective therapies.

A surprising cause of masses in the chest.

An 82-year-old male presented to the emergency department with an acute onset of chest pain and mild shortness of breath at rest. The pain in his left lower chest was pleuritic with intensity 9- on a 10-point scale. He had driven 2 h in his car that day, but had no other prolonged immobility.
