A 29-year-old woman presents to the clinic with a 6-week history of a painless, enlarging mass in her right supraclavicular region. She also reports experiencing drenching night sweats and a 5-kilogram (11-pound) weight loss over the past two months. Physical examination confirms a 3.5-centimeter, firm, mobile, non-tender right supraclavicular lymph node. Arrange the following steps in the most appropriate clinical sequence for establishing the diagnosis, evaluating the neoplastic process, and determining management, from first to last.
- 1Perform an excisional lymph node biopsy of the supraclavicular mass.
- 2Conduct histopathologic evaluation and immunohistochemistry (e.g., CD15, CD30).
- 3Obtain a whole-body integrated FDG-PET/CT scan.
- 4Initiate stage-adapted multi-agent systemic chemotherapy.
Cevap
The correct clinical sequence is: 1) Excisional lymph node biopsy, 2) Histopathologic and immunohistochemical evaluation, 3) FDG-PET/CT staging, and 4) Initiation of stage-adapted chemotherapy.
The correct progression in oncologic management for a patient presenting with high-risk 'B symptoms' and painless adenopathy prioritizes tissue acquisition with intact architecture (excisional biopsy). This allows pathologists to evaluate the neoplastic process at the cellular level and apply specific immunohistochemical markers. Only after a malignant diagnosis is confirmed is the patient subjected to the radiation and cost of a staging PET/CT, which subsequently provides the anatomic map required to tailor the final step: stage-adapted chemotherapy.

Anahtar Kavram
The evaluation of suspected lymphoma requires securing an architectural tissue diagnosis (excisional biopsy) and confirming molecular/cellular markers (immunohistochemistry) prior to comprehensive radiologic staging (PET/CT) and treatment initiation.
