Clinical T

This input is used for staging

Notes

**Note 1:** Assign 88 for in situ cases (behavior code /2). TNM nor FIGO include an in situ category for sarcomas of the corpus. **Note 2:** 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 FIGO III [NOS] or IIIC assign the appropriate stage and leave clinical T, N, and M blank. If the only information is FIGO stage IVB, leave T and N blank and see M **Note 3:** Tumor size must be known to assign a value of T1a or T1b. You may use a physician’s statement of the T category if this is the only information in the medical record. * If the tumor appears to be in the T1 category, but no size or category is specified, assign T1

c2B	cT2b	Tumor involves other pelvic tissues	Extension to : Ureter Vulva Extension or metastasis to: Cul de sac (rectouterine pouch) Parietal serosa of pelvic cavity Pelvic wall(s) Vagina Described clinically as "frozen pelvis", NOS FIGO Stage IIB Stated as T2b
c3	cT3	Tumor involves abdominal tissues	Note: T3 has subcategories of T3a and T3b. Assign T3 only when there is no information available to assign one of the subcategories Stated as T3 [NOS]
c3A	cT3a	One site	Infiltration of abdominal tissues, one of the following sites: Abdominal serosa (visceral or parietal peritoneum of abdomen) Sigmoid colon Small intestine Other abdominal tissues FIGO Stage IIIA Stated as T3a
c3B	cT3b	More than one site	FIGO Stage IIIB Stated as T3b

88	88	Not applicable	In situ case but no pTis is defined by TNM Death certificate only (DCO) case
<BLANK>	BLANK	See Registrar Notes	Only information is FIGO Stage III [NOS], IIIC, or IVB Clinical classification not met Clinical classification criteria met, evaluation done: No information about diagnostic workup Results not documented in record Clinical evaluation of primary tumor not done or unknown if done Tumor first detected on surgical resection (no clinical workup) Evidence of metastatic disease [(cM1) or (pM1)], no other workup
