This view displays the TNM formula.Please select appropriate value from the list for T/N/M/G variables. The result will be displayed, based on your selection of variables.

Pathological T (pT)

pT Category FIGO Stage pT Criteria
pTX N/A Primary tumor cannot be assessed
pT0 N/A No evidence of primary tumor
pT1 I Tumor limited to ovaries (one or both) or fallopian tube(s)
pT1a IA Tumor limited to one ovary (capsule intact) or fallopian tube, no tumor on ovarian or fallopian tube surface; no malignant cells in ascites or peritoneal washings
pT1b IB Tumor limited to both ovaries (capsules intact) or fallopian tubes; no tumor on ovarian or fallopian tube surface; no malignant cells in ascites or peritoneal washings
pT1c IC Tumor limited to one or both ovaries or fallopian tubes, with any of the following:
pT1c1 IC1 Surgical spill
pT1c2 IC2 Capsule ruptured before surgery or tumor on ovarian or fallopian tube surface
pT1c3 IC3 Malignant cells in ascites or peritoneal washings
pT2 II Tumor involves one or both ovaries or fallopian tubes with pelvic extension below pelvic brim or primary peritoneal cancer
pT2a IIA Extension and/or implants on the uterus and/or fallopian tube(s) and/or ovaries
pT2b IIB Extension to and/or implants on other pelvic tissues
pT3 III Tumor involves one or both ovaries or fallopian tubes, or primary peritoneal cancer, with microscopically confirmed peritoneal metastasis outside the pelvis and/or metastasis to the retroperitoneal (pelvic and/or para-aortic) lymph nodes
pT3a IIIA2 Microscopic extrapelvic (above the pelvic brim) peritoneal involvement with or without positive retroperitoneal lymph nodes
pT3b IIIB Macroscopic peritoneal metastasis beyond pelvis 2 cm or less in greatest dimension with or without metastasis to the retroperitoneal lymph nodes
