A series of three deep cough morning sputum specimens has a 66% sensitivity for confirming lung carcinoma.4 A single sputum specimen has a sensitivity of 0.1-0.7, averaging 0.22 in a review of published studies.5 There is a small gain in additional specimens (up to five). Additional testing is proposed to . However, cervical cytology has two main limitations as a primary screening test: its moderate sensitivity (50-70%) for detection of high-grade CIN and its limited reproducibility due to its . Besides initial diagnosis of lymphoma, it helps in detection of residual disease, recurrences and progression of low‐grade to high‐grade lymphoma, and helps in staging the disease. Due to the limitations of sputum cytology, additional testing is recommended when the test comes back with a negative result (showing no cancer) in patients where lung cancer is suspected to conclusively determine the presence or absence of lung cancer. Thus exfoliative cytology used alone would have led to a false negative diagnosis in 10 out of 16 (62%) of the cases with epithelial atypia verified by histology. One of the major limitations of the programme is the late stage at presentation of common cancers thus reducing the chances of survival. Most urologists understand the inherent limitations of cytology in diagnosing low-grade and noninvasive lesions due to their cellular cohesiveness and lack of nuclear atypia/dysplasia. Therefore not all patients will have their specimen reviewed by a pathologist trained or experienced in stringent criteria required for adequate criteria. • bone marrow core biopsies.

The inclusion of cytology specimens in clinical trials would expand patients&#x27; access to testing and treatment, yet there is a scarcity of clinical trial data regarding the application of IPOX to cytology, which can be attributed to trial designers&#x27; lack of familiarity with the advantages and limitations of cytology.
