Evaluating implementation of NCCN guideline-directed genetic screening recommendations for patients with pancreatic ductal adenocarcinoma.

PURPOSE: In 2019, the National Comprehensive Cancer Network (NCCN) recommended genetic testing for all patients with pancreatic ductal adenocarcinoma (PDAC). To evaluate the status of implementation of these guidelines in a loco-regional setting, we performed a retrospective, observational study among patients with newly diagnosed PDAC who received oncologic care at Northeast Georgia Medical Center in Georgia. METHODS: Chart abstraction of patients with newly diagnosed PDAC from 1 January 2020 to 31 December 2021 was performed to include information on genetic testing recommendation and completion, and time from diagnosis to testing. The deidentified dataset was then analyzed using appropriate descriptive and associative statistical testing. RESULTS: Of the cohort of 109 patients, 32 (29.4%) completed genetic screening; 16 (14.7%) were screened within 10 days of diagnosis. Among the 77 (70.6%) patients who did not receive genetic screening, 45 (41.3%) were not recommended genetic screening despite treatment intent with standard of care therapy. However, 32 (29.4%) were not recommended genetic screening in conjunction with a desire to pursue palliative care/hospice/or due to terminal illness. CONCLUSIONS: The study highlighted the gap in implementation of NCCN guideline-directed genetic testing in PDAC patients as only a third underwent testing suggesting the need for systematic processes to facilitate testing. The test was more likely to be completed if done early in the course, especially soon after the diagnosis. Research is needed to explore discussing genetic testing for the large proportion of patients who are terminally ill at diagnosis where genetic screening would potentially benefit the family members.

A Rare Case of Good Outcome of Hodgkin Lymphoma in a Patient with HIV on Antiretroviral Therapy (ART).

BACKGROUND Recent reports have shown an increased incidence of Hodgkin lymphoma (HL) in patients treated with antiretroviral therapy (ART) for human immunodeficiency virus (HIV) infection. This report is of a case of nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) with a good outcome in a 58-year-old Nigerian HIV-positive man who was being treated with ART. CASE REPORT A 58-year-old HIV-positive man presented to a clinic for evaluation of a left axillary mass. He was diagnosed with HIV in 2005, which was well-controlled by ART. He reported intermittent swelling in the left axillary region for several years. Results of a physical examination were significant for mild tender left anterior axillary lymphadenopathy. He had a computed tomography (CT) scan of the chest and neck, which showed left axillary adenopathy, with the largest measuring 3.5×2.0 cm. A staging positron emission tomography-computed tomography (PET/CT) showed focal uptake in 2 left axillary lymph nodes with no other sites involved. He underwent excision of the left axillary lymph node. Histopathology was consistent with nodular lymphocyte-predominant-type Hodgkin's lymphoma (NLHPL). He underwent radiation therapy with a total dose of 3600 centigray (cGy) according to National Comprehensive Cancer Network (NCCN) guidelines. The 5-month follow-up PET/CT scan showed no evidence of malignancy. CONCLUSIONS We present a case of HIV-associated NLHPL that had an indolent course and a good treatment outcome. This case highlights the importance of regular physical examination in HIV patients while on treatment with ART and accurate diagnosis of the cause of lymphadenopathy to prevent extra-nodal spread in cases of lymphoma.
