Squamous cell carcinoma (SCC) of cervical origin with metastasis to the brain is rare. Our patient was a 30-year-old Caucasian female with squamous cell carcinoma, initially with unknown primary, with metastases to the brain, kidney, cervix, lung, adrenal glands, vulva, pelvic wall, and scalp. She initially presented to her outpatient gynecologist for a vulvar mass. A biopsy of the vulvar mass was consistent with SCC. The patient continued to have fatigue along with thoracic rib pain. An initial work-up was performed, including imaging which showed diffuse metastatic disease involving the lungs, kidneys and adrenal glands, as well as a pathological compression fracture of the seventh thoracic vertebra with cord compression. Brain magnetic resonance imaging (MRI) showed multiple metastatic lesions and she underwent craniotomy for brain lesion resection. Given the aggressive nature of the patient’s disease and her symptomatic burden, she was started on chemotherapy in the hospital with Carboplatin, Paclitaxel, and Pembrolizumab.
BackgroundMany co-existing medical conditions may affect the outcome in patients treated with immune checkpoint inhibitors for advanced cancer. There is currently not any information on whether metabolic syndrome (MetS) impacts the clinical outcome in patients treated with immune checkpoint inhibitors (ICIs) for advanced non-small cell line cancer (NSCLC).MethodsWe carried out a single-center retrospective cohort study to determine the effects of MetS on first-line ICI therapy in patients with NSCLC.ResultsOne hundred and eighteen consecutive adult patients who received first-line therapy with ICIs and had adequate medical record information for the determination of MetS status and clinical outcomes were included in the study. Twenty-one patients had MetS and 97 did not. There was no significant difference between the two groups in age, gender, smoking history, ECOG performance status, tumor histologic types, pre-therapy use of broad-spectrum antimicrobials, PD-L1 expression, pre-treatment neutrophil:lymphocyte ratio, or proportions of patients who received ICI monotherapy or chemoimmunotherapy. With a median follow-up of 9 months (range 0.5-67), MetS patients enjoyed significantly longer overall survival (HR 0.54, 95% CI: 0.31-0.92) (p = 0.02) but not progression-free survival. The improved outcome was only observed in patients who received ICI monotherapy and not chemoimmunotherapy. MetS predicted for higher probability of survival at 6 months (p = 0.043) and 12 months (p = 0.008). Multivariate analysis indicated that, in addition to the known adverse effects of use of broad-spectrum antimicrobials and the beneficial effects of PD-L1 (Programmed cell death-ligand 1) expression, MetS was independently associated with improved overall survival but not progression-free survival.ConclusionsOur results suggest that MetS is an independent predictor of treatment outcome in patients who received first-line ICI monotherapy for NSCLC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
