Pathologic T
This input is used for staging
Notes
**Note 1:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and extension information on the primary tumor are available, use the extension information to assign the T in preference to a statement of FIGO stage - see Registrar notes. * If the only information is (pathologic) FIGO stage III [NOS] or IIIC, assign the appropriate stage and leave pathologic T, N, and M blank. If the only information is FIGO stage IV, leave T and N blank and see M **Note 2:** Primary peritoneal carcinomas may not involve the ovaries or only involve the ovaries "with minimal surface implants. The clinical presentation, surgical therapy, chemotherapy, and prognosis of these peritoneal tumors mirror those of papillary serous carcinoma of the ovary. Patients who undergo prophylactic oophorectomy for a familial history of ovarian cancer appear to retain a 1 to 2% chance of developing peritoneal adenocarcinoma, which is histopathologically and clinically similar to primary ovarian cancer.NAACCR Item
NAACCR #880| Pathologic T | Pathologic T Display | Description | Registrar Notes |
|---|---|---|---|
| pX | pTX | Primary tumor cannot be assessed | Pathologic classification criteria met, evaluation done: Physician unable to assess T Surgical resection of primary tumor, extension not stated Physician assigns cTX, no other information available to determine T |
| p0 | pT0 | No evidence of primary tumor | |
| p3 | pT3 | Tumor involves one or both ovaries WITH microscopically confirmed peritoneal metastasis outside the pelvis and/or regional lymph node metastasis |
Note: T3 has subcategories of T3a, T3b and T3c. Assign T3 only when there is no information available to assign one of the subcategories. Peritoneal implants, NOS Stated as T3 [NOS] |
| p3A | pT3a | Microscopic peritoneal metastasis beyond pelvis | Microscopic peritoneal implants beyond pelvis including: Liver capsule Mesentery Omentum Pericolic gutter Microscopic peritoneal implants beyond pelvis including peritoneal surface/capsule of: Ascending colon Descending colon Diaphragm Esophagus Gallbladder Transverse colon and flexures Small intestine Spleen Stomach WITHOUT invasion of underlying structures FIGO Stage IIIA Stated as T3a |
| p3B | pT3b | Macroscopic peritoneal, metastasis beyond pelvis, 2 cm or less in greatest dimension | Macroscopic peritoneal implants beyond pelvis less than or equal to 2 cm in diameter: Ascending colon Descending colon Diaphragm Esophagus Gallbladder Liver capsule Mesentery Omentum Pericolic gutter Transverse colon and flexures Small intestine Spleen Stomach WITH or WITHOUT invasion of underlying structures FIGO Stage IIIB Stated as T3b |
| p3C | pT3c | Peritoneal metastasis beyond pelvis, more than 2 cm in greatest dimension and/or regional lymph node metastasis | Macroscopic peritoneal implants beyond pelvis greater than 2cm in diameter: Ascending colon Descending colon Diaphragm Esophagus Gallbladder Transverse colon and flexures Liver Small intestine Spleen Stomach WITH or WITHOUT invasion of underlying structures Extension to: Bone Cartilage Further contiguous extension Stated as T3c |
| 88 | 88 | Not applicable | Primary site/histology not TNM defined Death certificate only (DCO) case |
| <BLANK> | BLANK | See Registrar Notes | Only information is FIGO Stage III [NOS], IIIC, or IV Pathologic classification not met Pathologic classification criteria met, evaluation done: Results not documented in patient record No surgical resection of known primary tumor (not T0) OR Resection insufficient for site-specific pathologic assessment No surgical resection of primary tumor and there isn't a positive biopsy of a structure in the highest T category and highest N category Evidence of metastatic disease (pM1), no other workup |
