Factors leading to delay in diagnosis of invasive cervical cancer

Objective: Screening for cervical cancer has been one of the major successes in American health care. The reasons for screening failure have not been well described. We have encountered 24 patients in the past year on our gynecologic oncology service who have presented with grossly visible stage IB or higher cervical cancers. A questionnaire was developed to determine why these patients presented with invasive cervical cancer, a theoretically preventable disease.Methods: All patients seen at our hospital center with grossly visible cervical cancer were offered entry into this prospective study, approved by the IRB. After informed consent was obtained, a questionnaire was administered to the patients by a physician. The questions involved sexual and gynecologic history, symptom review, social history, and personal concerns involving gynecologic exams. Twenty-four patients were approached for the study and 20 were enrolled. Four patients were unable to participate secondary to medical or social conditions that did not allow them to complete the questionnaire.Results: Of the 20 patients enrolled in this study, 14 of 20 (70%) presented with bleeding irregularities. Upon further questioning, 19 of 20 (95%) reported a history of abnormal bleeding. Only 3 of 20 (15%) patients reported a history of an abnormal Papanicolaou smear, and 7 of 20 (35%) reported not having had a Papanicolaou in the past 5 years. Two patients had never had a Papanicolaou smear. Seventeen of 20 (85%) of all patients in the study had medical insurance at the time of diagnosis, and only 2 patients reported lack of insurance as the reason they had not been seen by a gynecologist in the past 2 years. The majority of the study patients, 17 of 20 (85%) had contact with medical personnel in the 2 years prior to diagnosis. Sixteen of the 20 patients had been seen by a physician, 5 of 20 had surgery or other invasive procedures, and 6 of 20 had been seen in an emergency department. Only 5 of 20 patients knew that a Papanicolaou smear is a screening test for cervical cancer. Five of the 20 thought it to be a test for infections, and 10 of 20 did not know the purpose of a Papanicolaou smear. The main reason women gave for not having had a Papanicolaou smear in the past 2 years was that they felt healthy and had no symptoms (12/20).Conclusion: The majority of patients in our study (17/20) reported contact with a physician within 2 years of diagnosis of their invasive cervical cancer. It appears that failure to screen and lack of understanding regarding Papanicolaou smear screening, rather than lack of access to medical care, is a major cause for delay in diagnosis of cervical cancer.
