Title: How to followup patients


1
How to follow-up patients
  • Professor Gordon Rustin
  • Director of Medical Oncology
  • Mount Vernon Cancer Centre
  • Northwood
  • UK

2
Why do we follow-up patients who have had germ
cell tumors?
  • To detect relapse in the belief that earlier
    detection improves chance of cure
  • To detect contralateral testis tumors
  • To manage late toxicity
  • For reassurance, support and counselling
  • To collect data

Seminoma 10-year cause-specific survival 68 in
all patients 50 in patients relapsing with vital
malignant tumour 100 in those with teratoma/
necrosis before or after salvage chemotherapy.

ESMO Minimum Clinical Recommendations for
Follow-up for stage 1 seminoma after adjuvant
therapy
Chest X-ray and clinical examination at 1 month,
Then three monthly for 2 years Then 6 monthly to
5 years Pelvic CT in patients treated by
paraaortic strip (and abdominal CT in patients
treated by carboplatin) at year 1,2 and

12
ESMO Minimum Clinical Recommendations for
Follow-up of seminoma after metastatic disease
If normal CT scan follow-up as for stage 1 If
abnormal post-treatment CT scan repeat CT scan
every 6 months until normal or abnormalities
stabilised A PET scan may help identify residual
active cancer Consider biopsy or resection for
large residual or growing masses Huddart RA Ann
Oncol 18, Suppl2 ii40-ii41, 2007
13
Risks of excess CT scans
  • Typical chest CT has an associated radiation dose
    equivalent to 400 chest X-rays (8 vs 0.02 mSv)
    (Royal College of Radiologists, 1998)
  • Whole trunk CT produces dose of 10 to 30 mSv
  • Typical whole trunk CT scan associated with a
    11000 risk of cancer/leukaemia

16
Questions related to follow-up of patients with
germ cell
  • How many different follow-up schedules should be
    running?
  • Could follow-up be nurse led?
  • Is AFP necessary if pure seminoma?
  • Is LDH of value in follow-up?
  • Is Chest X-Ray necessary if no lung metastases
    at time of treatment for metastases?

17
LDH should not be measured routinely in follow-up
of germ cell tumours
125 of 494 stage I patients had elevated LDH at
relapse but in no case was it the first or only
sign of relapse Ackers Rustin BJC 94 1231-2,
2006 499 patients on surveillance or follow
up 26 of 1777 samples (1.4) true positive, 137
(7.7) false positive Only elevated marker at
relapse in 1 of 15 relapses. Contributed to
relapse detection in 4 of 35 (11)

Malignant teratoma 32 years after treatment of
germ cell tumor confined to testis.Pavic M,
Meeus P, Treilleux I, Droz JP. Urology. 2006

Is this the latest relapse after treatment of a
germ cell tumour?
19
How should we organise our follow-up to detect
the rare very late relapse?
Relapse after 10 years is seen in lt 1 of germ
cell patients These patients can be cured by
treatment that usually includes surgery Patients
should be warned about late relapse but their
rarity should not lead to prolonged follow-up
