A Hispanic man, aged 42 years, was diagnosed with stage IV metastatic urothelial bladder cancer (MUBC) with nonregional lymphadenopathies and lung, bone, and skin involvement. He received first-line treatment with gemcitabine and cisplatin for 6 cycles, achieving a partial response (PR). Next, he received immunotherapy maintenance with avelumab for 4 months until disease progression. A next-generation sequencing test of paraffin-embedded tumor tissue identified a fibroblast growth factor receptor 3 (FGFR3) S249C missense mutation...

OBJECTIVES: We present our experience with and data about a very rare neoplasm of the kidney, squamous cell carcinoma (SCC). METHODS: A total of 14 patients with a diagnosis of SCC were identified on the basis of a retrospective analysis of medical records of patients who underwent surgery for renal cancers between 2015 and 2021 at the Sindh Institute of Urology and Transplantation. IBM SPSS v25 was used to record and analyze data. RESULTS: Most patients found to have SCC of the kidney were male (71...

BACKGROUND: Immune checkpoint inhibitors (ICIs) that block PD-1/PD-L1 have consistently demonstrated durable clinical activity across multiple histologies but have low overall response rates for many cancers-indicating that too few patients benefit from ICIs. Many studies have explored potential predictive biomarkers (eg, PD-1/PD-L1 expression, tumor mutational burden [TMB]), no consensus biomarker has been identified. METHODS: This meta-analysis combined predictive accuracy metrics for various biomarkers, across multiple cancer types, to determine which biomarkers are most accurate for predicting ICI response...

As a locally aggressive primary benign tumor, giant cell tumor of bone (GCTB) presents a challenge to surgeons, as it often recurs regardless of surgical resection. This report describes a case of GCTB of the distal femur in a man, aged 39 years, treated with intralesional curettage through an arthroscopic approach. A 360° view of the tumor cavity can be achieved with the help of an arthroscope, which can help complete intralesional curettage and minimize possible larger approach-related complications...

PURPOSE: To assess the ability of circulating tumor DNA (ctDNA)-based testing to identify patients with HER2 (encoded by ERBB2)-positive gastric/gastroesophageal adenocarcinoma (GEA) who progressed on or after trastuzumab-containing treatments were treated with combination therapy of anti-HER2 and anti-PD-1 agents. METHODS: ctDNA analysis was performed retrospectively using plasma samples collected at study entry from 86 patients participating in the phase 1/2 CP-MGAH22-05 study (NCT02689284)...

The treatment of patients with relapsed and refractory multiple myeloma has become increasingly complex due to the rising number of available therapies. Patients are also increasingly exposed to, and refractory to, multiple classes of therapy at the time of progression. Patients who are at an early point in their myeloma disease course are likely to have several effective options, but choices and prognosis are limited for relapsing patients who are more heavily pretreated, particularly if they are at least triple-class refractory...

BACKGROUND: Glioblastoma is the most common primary neoplasm of the central nervous system. Standard treatment includes surgery with maximum safe resection and radiotherapy plus concomitant and adjuvant chemotherapy; however, almost invariably, tumor relapse occurs. We aimed to describe signaling pathways and molecular mechanisms present in tumor relapse of glioblastoma. METHODS: This systematic review followed the PRISMA guidelines. We searched the PubMed, EMBASE and Web of Science databases...

BACKGROUND: Mitogen-activated protein kinase (MEK) inhibitors, which integrate the important signaling chain of the RAS-RAF-MEK-ERK1/2 pathway, regulate cell functions such as division and proliferation for patients with solid tumors. However, various ocular adverse effects (AEs) affect patients during clinical treatment. This systematic review aimed to assess the occurrence of AEs during treatment with MEK inhibitors plus targeted therapy or chemotherapy. METHODS: A scientific literature search was conducted in PubMed, the Cochrane Library, Embase, and several Chinese databases to identify randomized controlled trials...

Cutaneous T-cell lymphomas (CTCLs) are clinically heterogeneous T-cell lymphomas that arise in the skin and are characterized by their clinical and pathological features. This review will focus on mycosis fungoides (MF) and Sézary syndrome (SS), which represent 60% to 80% and less than 10% of CTCL cases, respectively. While most patients with MF present with patches and plaques and can be successfully treated with skin-directed therapies, a minority of patients progress from early to advanced stages or undergo large cell transformation...

COVID-19 continues to disproportionately affect patients with cancer because of their underlying immunocompromised state. Strategies to mitigate the impact of COVID-19 on patients with cancer include vaccination, which has demonstrated some level of protection, at least against serious complications such as respiratory failure and death, with limited safety concerns. In this narrative review, we discuss the current COVID-19 vaccines that are available in the United States, the published data regarding vaccine efficacy and safety in patients with cancer, current vaccination guidelines, and future directions...

Richard L. Martin III, MD, MPH, and Stephen Schleicher, MD, MBA, share a perspective on rural cancer care.

BACKGROUND AND PURPOSE: Currently, there is no standard treatment for patients with lung cancer with deteriorated pulmonary function. In this study, we aimed to assess the efficacy of thoracic radiotherapy for unresectable non-small cell lung cancer (NSCLC) with baseline severe pulmonary dysfunction and severe acute radiation pneumonitis (SARP). METHODS: Patients were categorized into a radiotherapy group and a nonradiotherapy group, followed by analysis of clinical variables...

BACKGROUND: Cancer care in rural areas poses unique challenges, including access and proximity to care. This study examined differences in time to treatment initiation (TTI), a potential surrogate for access, and predictors of overall survival (OS) between rural and nonrural patients with breast cancer. METHODS: Women with stage I to III breast cancer diagnosed between 2004 and 2012 in facilities accredited by the National Cancer Database of Commission on Cancer (CoC) were included...

OBJECTIVES: To assess the effectiveness and toxicity of regorafenib in patients with metastatic colorectal cancer (mCRC) in routine clinical practice, as well as predictive factors of effectiveness. METHODS: This was a retrospective multicenter study in patients with mCRC who received regorafenib from November 2013 to May 2020. Effectiveness was evaluated by overall survival (OS) and progression-free survival (PFS) using the Kaplan-Meier method. Cox regression was performed to determine survival predictors...

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma. Historically, radiation therapy (RT) served as the primary treatment modality for patients with localized disease. While still an option for select patients who are not candidates for systemic therapy, RT is currently used most frequently as a consolidation treatment after chemoimmunotherapy. Consolidation RT is most commonly recommended after an abbreviated course of systemic therapy in patients who have bulky disease or multiple risk factors, or in the setting of a partial response...
