For each of the following patients presenting with a surgical condition of the breast or endocrine system, select the most appropriate operative intervention.

  • A 32-year-old pregnant female at 14 weeks gestation is evaluated for a newly diagnosed 2-cm invasive ductal carcinoma of the right breast.Total mastectomy with sentinel lymph node biopsy
  • An adult male undergoes fine-needle aspiration of a 2.5-cm solid thyroid nodule, which reveals medullary thyroid carcinoma; serum calcitonin is markedly elevated.Total thyroidectomy with prophylactic central compartment neck dissection
  • A young adult male with recurrent nephrolithiasis and a family history of prolactinomas and gastrinomas is confirmed to have primary hyperparathyroidism.Bilateral neck exploration with subtotal (3.5-gland) parathyroidectomy
  • A 55-year-old female with treatment-resistant hypertension has a 3-cm right adrenal mass; adrenal vein sampling confirms right-sided aldosterone overproduction.Laparoscopic unilateral adrenalectomy

Cevap

The correct operative management matches require recognizing specific contraindications (avoiding radiation in early pregnancy), natural disease progression (central lymph node spread in medullary thyroid cancer), underlying genetics (multiglandular parathyroid hyperplasia in MEN 1), and appropriate procedural selection for lateralized endocrine overproduction (unilateral adrenalectomy).
Each correct pairing applies core surgical principles: pregnant women in early gestation with breast cancer require mastectomy to avoid radiation; medullary thyroid cancer mandates central compartment neck dissection; MEN 1 hyperparathyroidism requires subtotal parathyroidectomy for multi-gland hyperplasia; and lateralized primary hyperaldosteronism is treated with unilateral adrenalectomy.

Adım Adım Çözüm

1
Analyze the breast cancer patient in early pregnancy.
Identified that breast-conserving surgery is unsafe because mandatory adjuvant radiation is teratogenic, and delaying radiation until postpartum is oncologically unsafe.
Dictates the necessity of choosing total mastectomy over lumpectomy.
2
Evaluate the management of medullary thyroid carcinoma.
Recognized that unlike well-differentiated thyroid cancers, medullary carcinoma requires concurrent central neck dissection.
Medullary thyroid carcinoma has a high rate of early lymphatic metastasis to the central neck.
3
Determine the etiology of hyperparathyroidism in the patient with a family history of pituitary and pancreatic tumors.
Diagnosed MEN 1 syndrome, which involves 4-gland parathyroid hyperplasia.
A localized, minimally invasive procedure would fail to cure the hyperparathyroidism; bilateral exploration is required.
4
Select the surgical approach for lateralized primary hyperaldosteronism.
Matched with laparoscopic unilateral adrenalectomy.
Adrenal vein sampling confirmed unilateral disease, making surgical resection the definitive cure.

Surgical management principles for breast and endocrine pathology require tailoring standard operations to account for physiologic states (pregnancy) and syndromic presentations (MEN 1).
