Karnataka PGET Gynecology MCQ Answer 2

The correct answer is A

Gestational trophoblastic tumors do not have an N classification. Pathologic staging is usually performed after surgical resection of the primary tumor. Pathologic staging depends on pathologic documentation of the anatomic extent of disease, whether or not the primary tumor has been completely removed.

AJCC/UICC TNM Classification for Trophoblastic Tumors

Primary Tumor (T)

• TX Primary tumor cannot be assessed
• T0 No evidence of primary tumor
• T1 Tumor confined to uterus
• T2 Tumor extends to other genital structures (vagina, ovary, broad ligament, fallopian tube) by metastasis or direct extension
  

Regional Lymph Nodes (N)

There is no regional nodal designation (N classification) in the staging of gestational trophoblastic tumors. Nodal involvement in these tumors is rare but has an extremely poor prognosis. Nodal metastases should be classified as metastatic M1b disease.

Distant Metastasis (M)

• MX Distant metastasis cannot be assessed
• M0 No distant metastasis
• M1 Distant metastasis
• M1a Metastasis to lung(s)#
• M1b Other distant metastasis (eg, brain) with or without lung metastasis#
  

# Genital metastasis (vagina, broad ligament, ovary, fallopian tube) is classified as T2. Direct invasion or metastasis to any non-genital structure is classified using the M classification.
