Key points

  • This list is a decision aid, not a rule; every item has exceptions. But each of these practices has shown harm or futility in studies or guidelines.
  • Most harm comes from "keeping old habits": chemotherapy that has been replaced by a targeted drug, or tests that do not change the outcome.

Treatment

  1. 1

    1. First-line chemoimmunotherapy (FCR, BR or chlorambucil) in CLL, especially with disrupted TP53 or unmutated IGHV

    Ibrutinib-rituximab had better progression-free and overall survival than FCR [4], and venetoclax-obinutuzumab (± ibrutinib) was superior to chemoimmunotherapy [5]. With disrupted TP53, chemotherapy is almost ineffective [16]. (More)

  2. 2

    2. Delaying ATRA when you suspect APL

    Start ATRA at the first clinical suspicion (pancytopenia, coagulopathy, promyelocytes on the smear) and before genetic confirmation; most deaths in the first days are from bleeding [6].

  3. 3

    3. Chemotherapy (instead of ATRA and arsenic) in low-risk APL

    ATRA with arsenic trioxide gave better event-free survival and less toxicity than ATRA with chemotherapy [7].

  4. 4

    4. First-line chemotherapy or immunotherapy in EGFR-mutated lung cancer

    First-line osimertinib increased progression-free and overall survival compared with older TKIs [8]; immunotherapy has little benefit in these patients. Know the EGFR and ALK status before treatment [17].

  5. 5

    5. A targeted drug without testing for the target

    Drugs such as cetuximab (without RAS wild type), trastuzumab (without HER2) or lung cancer TKIs (without a mutation) have no benefit and only add toxicity [2, 17].

  6. 6

    6. Chemotherapy in solid tumours with poor performance status (ECOG 3 to 4) without evidence of benefit

    In these patients, prioritise supportive and palliative care, unless the disease is highly treatment-sensitive (for example lymphoma, germ cell tumours, small cell lung cancer) or the weakness is caused by the cancer itself and is reversible [1].

Tests and imaging

  1. 1

    7. PET, CT or bone scan for staging early breast cancer (stage 0 to 2) or low-risk prostate cancer

    The chance of finding metastases is very low, and false findings lead to biopsies and delays [1].

  2. 2

    8. Tumour markers and routine imaging in the follow-up of treated breast cancer without symptoms

    Finding an asymptomatic recurrence earlier has not improved survival; examination and yearly mammography are enough [1].

  3. 3

    9. Starting rituximab or chemotherapy without testing for hepatitis B

    Check HBsAg, anti-HBc and anti-HBs before treatment; hepatitis B reactivation can be fatal and is preventable with antiviral prophylaxis [9].

  4. 4

    10. Starting a fluoropyrimidine without considering DPYD testing

    DPD deficiency causes fatal toxicity; genotype-guided dosing reduces this risk [10]. (Pharmacogenomics lesson)

Supportive care

  1. 1

    11. Primary G-CSF prophylaxis with low-risk regimens (below 20%) without risk factors

    It has no benefit and adds cost and bone pain [1, 11]. (G-CSF tool)

  2. 2

    12. Strong antiemetics (NK1) for low-emetogenic chemotherapy and multi-day dexamethasone without reason

    Prevention should match the emetogenicity of the regimen; too much dexamethasone has side effects [2, 12]. (Antiemetic tool)

  3. 3

    13. Transfusing at a haemoglobin above 7 to 8 in a stable patient without symptoms

    A restrictive threshold (7 g/dL; 8 in heart disease or orthopaedic surgery) is safe in most admitted patients [15]; give one unit at a time and reassess [3].

  4. 4

    14. Treating asymptomatic CLL or smouldering myeloma just because of a laboratory number

    In CLL, treatment starts only with the iwCLL criteria for active disease, not because of the lymphocyte count [16].

  5. 5

    15. Delaying referral to palliative care until the last days

    Early palliative care in advanced lung cancer improved quality of life, reduced depression and even prolonged survival [13]; ASCO recommends it for all patients with advanced disease from the first weeks [14].

For patients and families

If you have been offered a treatment that is on this list, ask why; sometimes there is a good reason. A simple version: Targeted therapy or chemotherapy?
