Testicular Cancer Stages
After someone is diagnosed with testicular cancer, doctors will try to figure out if it has spread, and if so, how far. This process is called staging. The stage of a cancer describes how much cancer is in the body. It helps determine how serious the cancer is and how best to treat it. Doctors also use a cancer's stage when talking about survival statistics.
The earliest stage of testicular cancer is stage 0 (also called germ cell neoplasia in situ, or GCNIS). The other stage groupings range from I (1) through III (3). There is no stage IV (4) testicular cancer. Some stages are split further to cover more details, using capital letters (A, B, etc.).
As a rule, the lower the number, the less the cancer has spread. A higher number, such as stage III, means cancer has spread more. And within a stage, an earlier letter means a lower stage. Although each person’s cancer experience is unique, cancers with similar stages tend to have a similar outlook and are often treated in much the same way.
How is the stage determined?
The staging system most often used for testicular cancer is the American Joint Committee on Cancer (AJCC) TNM system, which is based on 4 key pieces of information:
- The size and extent of the main tumor (T): How large is the tumor? Has it grown into nearby structures or organs?
- The spread to nearby lymph nodes (N): Has the cancer spread to nearby lymph nodes ? How many, and how big are they?
- The spread (metastasis) to distant sites (M): Has the cancer spread to distant parts of the body? (The most common sites of spread are distant lymph nodes, the bones, the liver, and the lungs.)
- The serum (blood) levels of tumor markers (S): Are any tumor marker levels higher than normal? This includes lactate dehydrogenase (LDH), human chorionic gonadotropin (HCG), and alpha-fetoprotein (AFP).
Numbers or letters after T, N, M, and S provide more details about each of these factors. Higher numbers mean the cancer is more advanced. Once a person’s T, N, M, and S categories have been determined, this information is combined in a process called stage grouping to assign an overall stage. For more on this, see Cancer Staging.
The system described below is the most recent AJCC system, effective as of January 2018. It's used for germ cell tumors (seminomas and non-seminomas) that occur after puberty, and for sex cord stromal tumors (Leydig cell tumors and Sertoli cell tumors).
Testicular cancer might be given a clinical T category (written as cT) based on the results of a physical exam, biopsy, and imaging tests (as described in Tests for Testicular Cancer). Once surgery is done, the pathologic T category (written as pT) is determined by examining tissue removed during the operation.
Testicular cancer staging can be complex, so ask your doctor to explain it to you in a way you understand.
Stages of testicular cancer
AJCC Stage |
Stage grouping |
Stage description* |
0 |
pTis |
The cancer is only in the seminiferous tubules (small tubes inside each testicle). It has not grown into other parts of the testicle (pTis). It hasn't spread to nearby lymph nodes (N0) or to distant parts of the body (M0). All tumor marker levels are within normal limits (S0). |
I |
pT1-pT4 |
The tumor has grown beyond the seminiferous tubules, and might have grown outside the testicle and into nearby structures (pT1-pT4). The cancer has not spread to nearby lymph nodes (N0) or to distant parts of the body (M0). Tumor marker test results aren’t available, or the tests haven’t been done (SX). |
IA |
pT1 |
The tumor has grown beyond the seminiferous tubules, but is still within the testicle, and it hasn't grown into nearby blood vessels or lymph nodes (pT1). The cancer hasn't spread to nearby lymph nodes (N0) or to distant parts of the body (M0). All tumor marker levels are within normal limits (S0). |
IB |
pT2-pT4 |
The tumor has grown outside of the testicle and into nearby structures (pT2-pT4). The cancer has not spread to nearby lymph nodes (N0) or to distant parts of the body (M0). All tumor marker levels are within normal limits (S0). |
IS |
Any pT (or TX) |
The tumor might or might not have grown outside the testicle (any pT), or the extent of the tumor can’t be assessed for some reason (TX). The cancer has not spread to nearby lymph nodes (N0) or to distant parts of the body (M0). At least one tumor marker level is higher than normal (S1-S3). |
II |
Any pT (or TX) |
The tumor might or might not have grown outside the testicle (any pT), or the extent of the tumor can’t be assessed for some reason (TX). The cancer has spread to 1 or more nearby lymph nodes (N1-N3), but it hasn't spread to distant parts of the body (M0). Tumor marker test results aren’t available, or the tests haven’t been done (SX). |
IIA |
Any pT (or TX) |
The tumor might or might not have grown outside the testicle (any pT), or the extent of the tumor can’t be assessed for some reason (TX). The cancer has spread to at least 1 nearby lymph node (but no more than 5, if checked by surgery), and none of the lymph nodes are larger than 2 centimeters (cm) across (N1). The cancer has not spread to distant parts of the body (M0). All tumor marker levels are within normal limits (S0), or at least 1 tumor marker level is slightly higher than normal (S1). |
IIB |
Any pT (or TX) |
The tumor might or might not have grown outside the testicle (any pT), or the extent of the tumor can’t be assessed for some reason (TX). The cancer has spread to at least 1 nearby lymph node that's larger than 2 cm but no larger than 5 cm across, OR it has grown outside of a lymph node, OR more than 5 nodes contain cancer (found during surgery) (N2). The cancer has not spread to distant parts of the body (M0). All tumor marker levels are within normal limits (S0), or at least 1 tumor marker level is slightly higher than normal (S1). |
IIC |
Any pT (or TX) |
The tumor might or might not have grown outside the testicle (any pT), or the extent of the tumor can’t be assessed for some reason (TX).
