(T) Primary Tumor

TNM

FIGO

Definitions

TX

 

Primary tumor cannot be assessed

T0

 

No evidence of primary tumor

Tis¹

 

Carcinoma in situ (limited to tubal mucosa)

T1

I

Tumor limited to the fallopian tube(s)

T1a

IA

Tumor limited to 1 tube, without penetrating the serosal surface; no ascites

T1b

IB

Tumor limited to both tubes, without penetrating the serosal surface; no ascites

T1c

IC

Tumor limited to 1 or both tubes with extension onto or through the tubal serosa, or with malignant cells in ascites or peritoneal washings

T2

II

Tumor involves 1 or both fallopian tubes with pelvic extension

T2a

IIA

Extension &/or metastasis of uterus &/or ovaries

T2b

IIB

Extension to other pelvic structures

T2c

IIC

Pelvic extension with malignant cells in ascites or peritoneal washings

T3

III

Tumor involves 1 or both fallopian tubes, with peritoneal implants outside the pelvis

T3a

IIIA

Microscopic peritoneal metastasis outside the pelvis

Χαρακτηριστικά Επέκτασης

  • Pattern of spread is similar to ovarian carcinoma
  • Peritoneal spread
    • In approximately 80% of patients with advanced disease, metastases are confined to peritoneal cavity
  • Lymphatic spread
  • Lymphatic drainage of PFTC mirrors that of uterine fundus and ovaries
    • Along ovarian vessels → paraaortic nodes
    • Along broad ligament → pelvic nodes
    • Along round ligament of uterus → superficial inguinal nodes
  • Early lymphatic metastases are common
  • Incidence of positive nodes is 40–60% when there is extratubal tumor spread
  • Can occur to liver, pleura, vagina, lungs, and brain
  • Spread to proximal part of fallopian tube and uterus
  • Hematogenous spread
  • Transluminal spread

Κατηγοριοποίηση (Ιστολογικοί Τύποι)

Primary fallopian tube Ca (PFTC) include

  • Papillary serous carcinoma (49.5-83.3%)
  • Endometrioid (8.3-50%)
  • Mixed (3.9-16.7%)
  • Clear cell (1.9%)
  • Transitional (11.7%)
