Lay Summary Biosimilar medications have the potential to significantly reduce the cost of treatment in patients with inflammatory bowel disease. Observational studies have shown similar efficacy and safety of biosimilars to biologic reference products. Shared decision-making is crucial to the successful implementation of these agents.

The NCCN Guidelines for Head and Neck Cancers address tumors arising in the oral cavity (including mucosal lip), pharynx, larynx, and paranasal sinuses. Occult primary cancer, salivary gland cancer, and mucosal melanoma (MM) are also addressed. The specific site of disease, stage, and pathologic findings guide treatment (eg, the appropriate surgical procedure, radiation targets, dose and fractionation of radiation, indications for systemic therapy). The NCCN Head and Neck Cancers Panel meets at least annually to review comments from reviewers within their institutions, examine relevant new data from publications and abstracts, and reevaluate and update their recommendations. These NCCN Guidelines Insights summarize the panel’s most recent recommendations regarding management of HPV-positive oropharynx cancer and ongoing research in this area.

PURPOSEAn ASCO provisional clinical opinion offers timely clinical direction to ASCO's membership following publication or presentation of potentially practice-changing data from major studies. This provisional clinical opinion addresses the appropriate use of tumor genomic testing in patients with metastatic or advanced solid tumors.CLINICAL CONTEXTAn increasing number of therapies are approved to treat cancers harboring specific genomic biomarkers. However, there is a lack of clarity as to when tumor genomic sequencing should be ordered, what type of assays should be performed, and how to interpret the results for treatment selection.PROVISIONAL CLINICAL OPINIONPatients with metastatic or advanced cancer should undergo genomic sequencing in a certified laboratory if the presence of one or more specific genomic alterations has regulatory approval as biomarkers to guide the use of or exclusion from certain treatments for their disease. Multigene panel–based assays should be used if more than one biomarker-linked therapy is approved for the patient's disease. Site-agnostic approvals for any cancer with a high tumor mutation burden, mismatch repair deficiency, or neurotrophic tyrosine receptor kinase ( NTRK) fusions provide a rationale for genomic testing for all solid tumors. Multigene testing may also assist in treatment selection by identifying additional targets when there are few or no genotype-based therapy approvals for the patient's disease. For treatment planning, the clinician should consider the functional impact of the targeted alteration and expected efficacy of genomic biomarker–linked options relative to other approved or investigational treatments.

Objective: To determine the effect of Selective Serotonin Reuptake Inhibitor (SSRI)/Selective Norepinephrine Reuptake Inhibitor (SNRI) use prior to or during admission for aneurysmal subarachnoid hemorrhage (aSAH) on the risk of symptomatic vasospasm and diffuse cerebral ischemia (DCI). Methods: Review of electronic records at Mayo Clinic, Rochester from Jan. 2001 to Dec. 2013 of consecutive patients with aSAH. The variables collected and analyzed were: age, sex, active smoking, transfusion, modified Fisher score, WFNS grade, and outcome at discharge. Multivariate logistic regression analysis was used to evaluate factors associated with DCI, symptomatic vasospasm, and poor outcome (modified Rankin score 3-6) within 1 year. Results: 583 [females 367 (63%)] patients with a median age of 55 (47-65) years were admitted with aSAH during the study period. WFNS at nadir was IV-V in 243 (41.6%) and modified Fisher score was 3-4 in 438 (75.2%). Eighty one (14.6%) patients were taking SSRI or SNRI prior to admission and these medications were continued in all of them. Symptomatic vasospasm was present in 154 (27.7%), radiological infarction in 172(29.5%), and DCI in 250(42.9%) patients. SSRI/SNRI use was not associated with the occurrence of DCI (p=0.458), symptomatic vasospasm (p=0.097), radiological infarction (p=0.972), or poor functional outcome (p=0.376). Conclusions: The use of SSRI/SNRI prior to admission and/or during hospitalization in patients with aSAH was not associated with symptomatic vasospasm or DCI.

BackgroundAlthough many patients with follicular lymphoma (FL) undergo routine radiographic surveillance during their first remission, no consensus exists on the modality, duration, frequency, or need for routine imaging studies. The authors retrospectively examined the effect of surveillance imaging on relapse detection and overall survival (OS) in patients with FL.MethodsPatients with newly diagnosed FL who had a response to induction therapy were identified from the Lymphoid Malignancies Enterprise Architecture Database (LEAD) at Emory University and from the Molecular Epidemiology Resource (MER) of the University of Iowa/Mayo Clinic. Patients were evaluated for both relapse and method of relapse detection (ie, clinical concerns vs radiologic detection through surveillance imaging in an asymptomatic patient).ResultsOf 148 patients in the LEAD cohort, 55 (37%) relapsed, and the majority (n = 35; 64%) of relapses were detected clinically. In the MER cohort, 63 of 177 relapses (54%) were detected clinically. There was no significant difference in OS from the date of diagnosis between the 2 methods of relapse detection in the LEAD (hazard ratio [HR], 0.61; 95% CI, 0.13‐2.94; P = .54) and MER (HR, 1.02; 95% CI, 0.47‐2.21; P = .96) cohorts. Similarly, there was no significant difference in OS from the date of relapse between the 2 methods of relapse detection in the LEAD (HR, 0.47; 95% CI, 0.10‐2.27; P = .35) and MER (HR, 1.02; 95% CI, 0.47‐2.21; P = .96) cohorts.ConclusionsThese findings suggest a limited role for routine surveillance imaging in patients with FL who complete front‐line therapy. Future studies should evaluate which patients may benefit from a more aggressive surveillance approach and should explore novel methods of relapse detection.
