IN SHORT

Three results set the stage together: the tumour type, the CT scan, and the AFP, hCG and LDH levels after the testis is out.

Stage I usually means close surveillance instead of more treatment. Spread to lymph nodes or beyond brings chemotherapy, surgery, or both.

For spread disease, the IGCCCG risk group fixes the chemotherapy: usually three BEP cycles in the good group, four in intermediate or poor.

Three things make the stage

After the testis is removed through the groin, three results together set the stage:

  1. The tumour type from the pathology report: seminoma, or non-seminoma (NSGCT). The two are treated differently at almost every stage.
  2. The CT scan of the chest, abdomen and pelvis: are the lymph nodes at the back of the abdomen enlarged, and how large? Is there spread to the lungs or other organs?
  3. The markers after surgery: AFP, beta-hCG and LDH. The value after the operation, not the one before, decides the marker part of the stage (the S category) and the risk group.

The order of these tests, and why the markers must be taken before the operation as well, is explained in testicular cancer tests in order. This page starts where that one ends: the results are in, and the question is what they mean.

What each stage means, and the usual path

StageWhat it meansUsual path
Stage ICancer confined to the testis; markers back to normal after surgerySurveillance in most men; a single preventive treatment in some
Stage IIALymph nodes at the back of the abdomen, up to 2 cmSmaller, targeted options in selected men, or chemotherapy
Stage IIBLymph nodes 2 to 5 cmSmaller, targeted options in selected men, or chemotherapy
Stage IICLymph nodes larger than 5 cmCisplatin-based chemotherapy, with surgery after it if a mass remains
Stage IIISpread beyond these nodes, such as to the lungs or other organsCisplatin-based chemotherapy by risk group, with surgery after it if a mass remains

This cancer usually responds well to treatment, even after it has spread. So the aim at every stage is the treatment the stage needs: not less, out of caution, and not more for a man who will do well with surveillance.

Stage I seminoma: surveillance first, and two features that open a second option

For stage I seminoma, surveillance is the recommended path. No further treatment is given; instead, regular markers and scans watch for any return, which is then treated.

Two features in the pathology report raise the chance of return: a tumour larger than 4 cm, and spread into the rete testis (the channels at the back of the testis). When either is present, one cycle of carboplatin is discussed as an alternative. Without them, extra treatment adds no real benefit.

Radiotherapy after the operation, once common, is now generally not advised for stage I seminoma, because of the risk of a new cancer in the treated area.

Surveillance only works if you can attend. If distance, travel for work or no phone will make visits hard, the single dose of carboplatin is discussed openly instead. The visit schedule is set out in testicular cancer follow-up.

Stage I non-seminoma: lymphovascular invasion is the feature to look for

For most men with stage I non-seminoma, surveillance is again the preferred path.

The feature that matters most is lymphovascular invasion (LVI): cancer cells seen inside small blood or lymph vessels in the removed testis. It raises the chance of return considerably. One cycle of BEP chemotherapy after the operation lowers that chance, and is discussed when LVI is present.

An operation to remove the lymph nodes at the back of the abdomen (RPLND) is used in selected stage I cases: for example, a teratoma with a non-germ-cell cancer growing inside it, or a man who cannot attend surveillance and does not want chemotherapy.

Stage IIA and IIB: when a smaller treatment may be enough

When lymph nodes are involved but not large, full chemotherapy is not the only route.

For seminoma with normal markers and nodes up to 3 cm, a nerve-sparing RPLND is now an accepted option. Focused radiotherapy with one cycle of carboplatin is another, in selected men. Otherwise, chemotherapy is given.

Nerve-sparing means the nerves that control ejaculation are kept wherever the cancer allows. Whether they could be kept is told to you in person after the operation.

Stage IIC and III: the risk group sets the chemotherapy

Once the cancer has spread further, chemotherapy with BEP (bleomycin, etoposide, cisplatin) is the main treatment. The international risk grouping (IGCCCG) decides how many cycles:

Risk groupSeminomaNon-seminomaUsual chemotherapy
GoodAny marker level; no spread to organs other than the lungsPrimary in the testis or behind the abdomen; no spread to organs other than the lungs; low markersThree cycles of BEP, or four of EP when bleomycin is not suitable
IntermediateSpread to organs other than the lungsIntermediate marker levelsFour cycles of BEP
PoorDoes not exist for seminomaPrimary in the chest (mediastinum), spread to organs other than the lungs, or high markersFour cycles of BEP

One recent change matters for seminoma. In the good group, an LDH more than 2.5 times the upper limit of normal behaves like the intermediate group, so most of these men are given four cycles rather than three.

The cycles are given on time. Doses are not cut or delayed for low blood counts without support to raise them, because keeping to the schedule is part of what makes the treatment work.

After chemotherapy: what a leftover mass means

A scan after chemotherapy may still show a lump in the abdomen. What happens next depends on the type:

  • Non-seminoma: any leftover mass of 1 cm or more, with normal markers, is removed by RPLND. It may contain teratoma, which chemotherapy does not treat and which can grow.
  • Seminoma: a leftover mass is usually watched. Surgery is considered only for a mass of 3 cm or more that lights up on a PET-CT done at least six to eight weeks after chemotherapy.

Surgery after chemotherapy is a major operation. The details are on surgery, sperm banking and nerve-sparing RPLND.

What does not change with the stage

Some things are the same for every man, whatever his stage or group:

  • Sperm banking is offered before any chemotherapy or RPLND, and your answer is written down.
  • A testicular prosthesis is offered and discussed.
  • Every case is discussed by the tumour board (MDT) after the operation, before any further treatment.

Reports can be sent ahead, so the consultation starts with them already read. Treatment is decided at the consultation, after examination.

Frequently asked questions

My markers were high before surgery and normal after. Which value sets my stage?

The value after surgery. The earlier one is the starting point; the stage and the risk group use the marker levels once the testis has been removed.

Why is there no poor risk group for seminoma?

In the international grouping, seminoma is placed only in the good or intermediate group. Spread to organs other than the lungs moves it to intermediate.

Does stage I mean I need no treatment at all?

Usually no further treatment is given, but surveillance is itself the treatment: regular markers and scans, kept on schedule, so any return is found early.

Will I need an operation on the lymph nodes?

Not usually in stage I. RPLND is used for a leftover mass after chemotherapy, in some small-node seminomas, and in selected stage I cases.

Is sperm banking needed if my stage is early?

It is offered to every man, at every stage, before chemotherapy or RPLND. Stage does not decide it; your wishes do.
