IN SHORT
When ovarian cancer looks limited to the ovary, the operation both treats it and proves how far it has gone. Until the pathology report, “early” is a working label.
Three things are settled before the operation: whether pregnancy is still wanted, the BRCA and HRD blood test, and consent for what the surgeon may find.
Chemotherapy after the operation is not automatic. The tumour board decides it from the final report: the confirmed stage, and the tumour’s type and grade.
Why “confined to the ovary” stays a working label until the report
Cancer of the ovary, the fallopian tube and the lining of the abdomen is treated as one disease. When the scan shows a mass in one or both ovaries and nothing elsewhere, the family hears the word early. It is a fair hope, but it is not yet a fact.
Ovarian cancer is staged at the operation, not on the scan. Thin deposits on the lining of the abdomen, or cancer cells floating in fluid, can be too small for any scan. So the operation for apparently early disease is built to look for them, and the stage is written only when the pathologist has examined everything that was removed. How each stage changes the plan is set out in the staging page; this page follows one woman whose scan looks early, from the first consultation to the first follow-up visit.
Three things settled before the operation
- Is a pregnancy still wanted? This has to be said before surgery, not after. Keeping the uterus and one ovary is possible only in a narrow group, and the counselling is written down.
- The BRCA and HRD test is sent at diagnosis. The result takes three to five weeks in India. It matters for later treatment choices and for the woman’s sisters and daughters, so it is not left for a relapse.
- Consent covers what may be found. If the operation shows spread that the scan missed, the aim becomes removing all visible disease. Consent for bowel surgery, and for a stoma if it is needed, is taken before the operation, every time.
Every case is discussed at the tumour board before the first treatment. Weight loss, low albumin or poor eating are checked at the first visit; any one of them brings in the dietitian and a short programme of walking and protein before surgery.
What the operation removes, and why each part matters
| Part of the operation | Why it is done |
|---|---|
| Fluid washings, taken before anything is handled | Cancer cells in the fluid can change the stage even when nothing is seen. |
| Biopsies from the lining of the abdomen, in a set pattern | Hidden deposits are looked for where the lining looks healthy. |
| Uterus, both tubes and both ovaries | Removes the tumour and lets the other organs be checked under the microscope. |
| Omentum, the fatty apron inside the abdomen | A standard part of staging; checked for hidden deposits. |
| Lymph nodes in the pelvis and along the aorta | Nodes can carry cancer that no scan shows. |
| Appendix, when the tumour is the mucinous type | Part of the staging operation for this type. |
Together these steps are called comprehensive staging surgery. Their purpose is to give the pathologist enough tissue to say with confidence that the cancer is, or is not, confined to the ovary. A smaller operation can remove the visible tumour and still leave the stage unknown, which leaves the next decision unanswerable.
When the uterus and the other ovary can be kept
For a young woman who wants a child, the operation can sometimes remove only the affected ovary and tube, with the full staging steps still done. Dr Swati Shah offers this only when all of these are true:
- The final stage is FIGO IA.
- It is grade 1 or 2.
- It is not the clear-cell type.
- She has a definite wish for pregnancy.
- She has been counselled, and that counselling is recorded.
Some of these answers, such as the grade and the type, are confirmed only on the final report. That is why the wish is stated before surgery and the plan is revisited when the report arrives. Outside this group the standard operation is advised. More detail is on the fertility page.
After the report: is chemotherapy needed?
The final report does two things. It confirms the stage, and it names the tumour’s type and grade. The tumour board reads it with the operation notes and decides whether chemotherapy should follow.
| What the report shows | What usually follows |
|---|---|
| Stage I confirmed | Chemotherapy may or may not follow; the board decides from the stage, type and grade |
| Spread within the pelvis (stage II) | Chemotherapy after the operation |
| Spread beyond the pelvis found at surgery | Treated as advanced disease; the plan is made afresh |
When chemotherapy is advised, the usual course is carboplatin with paclitaxel, given every three weeks for six cycles, under the medical oncologist. The appointment with the medical oncologist and the date for the report discussion are fixed before discharge, so nothing waits. Recovery in hospital is described in after ovarian cancer surgery.
Menopause, follow-up and testing the family
When both ovaries are removed, menopause begins at once and is permanent. This is a certainty, not a risk, and it is discussed before the operation. Hormone replacement is acceptable for most women with this type of cancer, after a discussion of her own report.
| When | What is checked |
|---|---|
| Two weeks after surgery | Wound, the final report, the BRCA and HRD result, referral to the medical oncologist |
| Every three months for two years | Symptoms, examination including the pelvis, weight, CA-125 |
| Every four to six months, years three to five | The same checks |
| Once a year after five years | Clinical review; the end of follow-up is decided individually |
Scans are not routine while she is well and the CA-125 is steady; a CT is done if the CA-125 rises or symptoms appear. A rising CA-125 on its own, in a woman who feels well, is not by itself a reason to restart chemotherapy. If the BRCA test is positive, her close relatives are offered testing, and the team follows it until it is done.
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 scan says stage I. Can the stage change after the operation?
Yes. The scan stage is provisional. Washings, biopsies or nodes can show spread the scan could not see, and the final stage comes from the pathology report.
Why remove lymph nodes if they looked normal on the scan?
Because small deposits in nodes are not visible on a scan. In apparently early disease, the pelvic and aortic nodes are removed so the stage is certain.
Can I keep my uterus if I want a child?
Possibly, if the cancer is stage IA, grade 1 or 2, not clear-cell, and you have a definite wish for pregnancy, after counselling that is recorded.
Will I need chemotherapy after the operation?
Not always. The tumour board decides from the final report. Stage II and higher usually receive chemotherapy; in stage I it depends on the type and grade.
Why is the BRCA test sent before treatment starts?
The result takes weeks, it guides later treatment, and it tells the family whether relatives should be tested. Waiting until a relapse loses that time.
