Mismatch repair deficiency and microsatellite instability in urothelial carcinoma: a systematic review and meta-analysis.

Background: Mismatch repair deficiency (dMMR) and microsatellite instability-high (MSI-H) occur in a subset of cancers and have been shown to confer sensitivity to immune checkpoint inhibition (ICI); however, there is a lack of prospective data in urothelial carcinoma (UC).

Methods And Analysis: We performed a systematic review to estimate the prevalence of dMMR and MSI-H in UC, including survival and clinical outcomes. We searched for studies published up to 26 October 2022 in major scientific databases.

New Therapeutic Horizons for Advanced or Metastatic Penile Cancer.

Penile cancer is a rare malignancy with a poor prognosis. Studies with single-agent immune checkpoint inhibitors (ICIs) have demonstrated efficacy, but response rates are low. Studies combining ICIs with both chemotherapy and targeted therapy are ongoing.

The management of toxicities from immune, targeted and ADCs treatments in patients with urothelial cancer.

Newly approved systemic treatment options for metastatic urothelial cancer (mUC) have diversified treatments and improved responses and survival for chemotherapy refractory disease. These systemic treatments have associated toxicities which need appropriate management for patients to stay on treatment and potentially have longer benefit from treatment. We review the expected toxicities of immune checkpoint inhibitors, FGFR inhibitors such as erdafitinib, and antibody drug conjugates such as enfortumab vedotin and sacituzumab govitecan.

A Case of Metastatic Pancreatic Adenocarcinoma in Complete Remission Using Chemotherapy and Immunotherapy.

Among the various types of cancer, pancreatic cancer is considered to have a particularly grim prognosis. Treatment includes surgery, chemotherapy, or both. While the role of immunotherapy is well-studied in many types of cancer, such is not the case with pancreatic cancer.

Management of men with metastatic castration-resistant prostate cancer following potent androgen receptor inhibition: a review of novel investigational therapies.

Background: Androgen-targeted therapy and chemotherapy are currently the mainstay of treatment in metastatic castration resistant prostate cancer (mCRPC). When progression occurs despite these therapeutic strategies, additional FDA-approved treatment options are lacking. However, there is a vast amount of emerging data surrounding novel investigational therapies in this space.

Pembrolizumab-Induced Cold Agglutinin Disease.

BACKGROUND The introduction of immunotherapy in the management of metastatic lung cancer appears to be changing their natural history. Most patients tolerate immunotherapy without any significant adverse events. Nevertheless, a significant number of patients still experience adverse effects.

A Unique Case of Severe Anemia Secondary to Copper Deficiency in an Adult Patient.

Anemia is a frequently encountered problem in the healthcare system. Common causes of anemia include blood loss, followed by impaired red blood cell production and red blood cell destruction. This case demonstrates the need for cognizance of the less frequent causes of anemia.

The Role of Immunotherapy and Radiation Therapy in Tumor Chemosensitivity in Advanced Head and Neck Cancer.

BACKGROUND Cancer is the second leading cause of death internationally, resulting in millions of deaths each year. While treatment in the past has heavily relied on surgery and radiotherapy, chemotherapy and immunotherapy are being increasingly utilized depending on disease presentation. CASE REPORT A 56-year-old male presented to the Emergency Department with a 3-week history of a rapidly enlarging left supraclavicular neck mass.
