Background: Accurate staging for small cell lung cancer (SCLC) is critical for determining appropriate therapy. The clinical impact of increasing PET adoption and stage migration is well described in non–small cell lung cancer but not in SCLC. The objective of this study was to evaluate temporal trends in PET staging and survival in the Veterans Affairs Central Cancer Registry and the impact of PET on outcomes. Patients and Methods: Patients diagnosed with SCLC from 2001 to 2010 were identified. PET staging, overall survival (OS), and lung cancer–specific survival (LCSS) were assessed over time. The impact of PET staging on OS and LCSS was assessed for limited-stage (LS) and extensive-stage (ES) SCLC. Results: From 2001 to 2010, PET use in a total of 10,135 patients with SCLC increased from 1.1% to 39.2%. Median OS improved for all patients (from 6.2 to 7.9 months), those with LS-SCLC (from 10.9 to 13.2 months), and those with ES-SCLC (from 5.0 to 7.0 months). Among staged patients, the proportion of ES-SCLC increased from 63.9% to 65.7%. Among 1,536 patients with LS-SCLC treated with concurrent chemoradiotherapy, 397 were staged by PET. In these patients, PET was associated with longer OS (median, 19.8 vs 14.3 months; hazard ratio [HR], 0.78; 95% CI, 0.68–0.90; P<.0001) and LCSS (median, 22.9 vs 16.7 months; HR, 0.74; 95% CI, 0.63–0.87; P<.0001) with multivariate adjustment and propensity-matching. In the 6,143 patients with ES-SCLC, PET was also associated with improved OS and LCSS. Conclusions: From 2001 to 2010, PET staging increased in this large cohort, with a corresponding relative increase in ES-SCLC. PET was associated with greater OS and LCSS for LS-SCLC and ES-SCLC, likely reflecting stage migration and stage-appropriate therapy. These findings emphasize the importance of PET in SCLC and support its routine use.

Background: Genomic sequencing of tumor samples is often considered for patients diagnosed with metastatic malignancies. In July 2016, the Veterans Health Administration (VHA) created the VA National Precision Oncology Program (NPOP) to offer next generation sequencing (NGS) multigene panels for veterans with advanced solid tumors. We sought to assess the perceptions of NPOP among medical oncologists across VHA. Methods: Semi-structured interviews were designed to evaluate the following concepts: expectations for NGS testing, required workflow to conduct testing, applicability of testing results, and summative views of genomic sequencing. VHA medical oncologists who had previously sent at least one sample for testing through NPOP were solicited to participate for an in-person or telephonic conversation. Interviews were analyzed by an inductive narrative approach to code responses, which was then followed by thematic analysis for key findings that emerged. Results: 17 medical oncologists were interviewed from 16 different VA medical centers (VAMCs) in 12 states. 16 (94.1%) oncologists reported sending at least 5 samples for NGS testing; 4 (23.5%) oncologists practiced at VAMCs that sent over 100 samples. Clinicians collectively expected that testing would determine all clinically relevant genomic alterations in a reasonable time. Testing was expedited for oncologists who maintained a collaborative relationship with their local pathologists and proceduralists. 8 (47.1%) oncologists felt that testing reports should provide greater insight into the clinical significance of uncommon gene variants. 6 (35.3%) respondents expressed that educational efforts are warranted to describe optimal sample processing, indications for testing, and/or relevance of rare mutations. Twelve (70.6%) respondents felt strongly that NGS testing would improve outcomes for their patients, while 3 (17.6%) oncologists were wary that the current number of actionable mutations is too limited to offer widespread benefit. Conclusions: VHA medical oncologists opined that NGS testing through VA NPOP improved outcomes. The testing process is expedited with multidisciplinary involvement. Designed approaches to semi-algorithmically report testing results may improve efficiency of clinical decision-making. More education is warranted to detail the procedural requirements to conduct testing, indications for test ordering, and interpretation of results.

The NCCN Guidelines for Hepatobiliary Cancers provide treatment recommendations for cancers of the liver, gallbladder, and bile ducts. The NCCN Hepatobiliary 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 discussion and updated recommendations regarding systemic therapy for first-line and subsequent-line treatment of patients with hepatocellular carcinoma.
