Quality control for colposcopy in the Florence screening program for cervical cancer.

The authors report on the quality control for colposcopy adopted in the Florence District screening program. The sensitivity of colposcopy was determined on all cases of CIN III recorded in the local cancer registry in a four-year period. However although this showed that a centralized colposcopic clinic employing a limited number of expert operators is superior to the performance of colposcopy in private practice, such a parameter was impractical for further routine quality control since differences among operators were too small and statistically insignificant. Other parameters for quality control were chosen, namely a) the rate of colposcopically directed biopsies performed, b) the detection rate of CIN II or more severe lesions, and c) the positive predictive value of a directed biopsy for CIN II or more severe lesions. Analysis of these indicators after stratification by cytologic report allows the identification of those operators who need additional training and provides useful information for colposcopists to optimize their diagnostic and operative criteria.

Evaluation of the sensitivity of cervicography in a consecutive colposcopic series.

Cervicography was performed in 606 women referred for colposcopy. Cervigrams were blindly reviewed by two independent readers. The positivity rate at cervicography was high (operator A = 50%, B = 58.8%). The sensitivity for papillomavirus infection (HPV)/cervical intraepithelial neoplasia I (CIN I) (n = 141) was 79.4% for operator A and 80.8% for operator B. The sensitivity for CIN II or more severe lesions (n = 22) was 95.2% and 90.5% for operators A and B, respectively. The positive predictive value for HPV/CIN I or CIN II, or more severe lesions was 36.9% and 6.9% for operator A and 32.1% and 5.3% for operator B, respectively. Interobserver variability was acceptable (kappa = 0.62). Cervicography suspected 27 HPV/CIN I, 1 CIN II and 1 CIN III which showed no cytologic abnormalities. This study confirms that cervicography has a good sensitivity for cervical lesions, but it is based on a selected series, not representative of a screening condition. The combination of cervicography and cytology in screening is presently under evaluation in a prospective study of screened women.

Hysteroscopy and endometrial cancer diagnosis: a review of 2007 consecutive examinations in self-referred patients.

The authors reviewed 2007 consecutive outpatient hysteroscopies performed in self-referred women to assess the detection rate of uterine cancer and the validity of different selection criteria for hysteroscopy. Thirty cases of uterine cancer (29 endometrial, 1 carcinosarcoma) were detected. Abnormal uterine bleeding was the indication most commonly associated with cancer (26 of 30 cases, cancer detection rate = 2.1%), whereas the presence of cervical polyps had no predictive value. Patients age was correlated to cancer detection rate, and the investigation of uterine cancer under the age of 45 was poorly cost effective. Hysteroscopy and endometrial biopsy, performed by Permacurette or Novak curette immediately after hysteroscopy, missed respectively 8 and 2 of 30 cancers. Hysteroscopy should be employed in combination with endometrial biopsy as a standard outpatient investigation whenever endometrial cancer is suspected. These procedures are safe and accurate and rule out more aggressive and costly procedures, such as dilatation and curettage, in most cases.

Response of primary breast cancer to tamoxifen alone in elderly women.

The authors report on a consecutive series of 62 evaluable, elderly (age greater than 69 years) women with primary operable breast cancer treated only with tamoxifen. The treatment schedule was 160 mg on day 1 followed by a daily maintenance dose of 20 mg. Compliance to treatment was excellent, and subjective side effects were minimal. The best response achieved after at least 6 months of treatment was complete in 7, partial in 22 and minor in 3, whereas stable disease or progression was observed in 28 and 2 patients, respectively. The response rate decreased and progressions increased with time. At 6, 12, 24, 36 and 48 months of treatment, the complete + partial response rates were 30.6%, 45%, 45.6%, 38.7% and 25% and the progressive disease rates 4.8%, 19.6%, 34.8%, 45.2% and 66.6%, respectively. These results do not confirm some previous reports of a high response to tamoxifen. This difference is only partially explained by the use of mammography, which is more sensitive than palpation, to assess tumor size and treatment response. The present study does not support primary hormone therapy as a current alternative to surgery, which should be the standard treatment in otherwise healthy elderly patients with operable breast cancer.

Subclinical vulvar papillomavirus infection.

Eighty-eight cases of subclinical human papillomavirus (HPV) vulvar infection were detected in a consecutive colposcopic series of 968 women. Three patterns of acetowhite lesions had a 72% predictive value (88/122) for histologically assessed HPV. The prevalence of subclinical vulvar HPV in self-referred patients was 7.9% (73/918); it was 9% (88/968) in the overall series and significantly higher in younger patients (age less than 25 years: 21/106, or 19.8%) or in those with cervical HPV or cervical intraepithelial neoplasia (CIN) (40/100, or 40%). Routine inspection of the vulva after acetic acid lavage in association with a Papanicolaou test might help identify Papanicolaou-test-negative patients at high risk of developing cervical HPV or CIN. Treatment with beta-interferon (2,000,000 IU daily intramuscularly for 10 days) was given to 30 consecutive patients, but the results were poor: regression was observed in only 2 cases.

Male breast carcinoma: review of a multicenter series of 150 cases. Coordinating Center and Writing Committee of FONCAM (National Task Force for Breast Cancer), Italy.

The authors report on a consecutive retrospective series of 150 male breast cancers. Clinical, diagnostic and therapeutic features are compared over time and with respect to a large consecutive series of female breast cancers. Both age at diagnosis and tumor stage were more advanced in males than in females. Poor alertness of both men and doctors for this infrequent disease may account for such a delay in diagnosis. The use of mammography increased over time and sonography or cytology were frequently and successfully employed in the last decade. Unfortunately no improvement of tumor stage at diagnosis was observed over time in the present series. A time trend was also evident for the type of surgical and postoperative treatment. Modified radical mastectomy and adjuvant chemo- or hormone therapy were increasingly adopted, although Halsted operation and postoperative radiotherapy were still common in the last decade due to the relatively high proportion of locally advanced T3-4 cancers. Both disease-free and overall survival were worse in men than in women, even after adjustment by stage at diagnosis. This study suggests that male breast cancer has a worse prognosis with respect to female breast cancer and provides no complete explanation of this finding, except for an intrinsic higher aggressivity. No evidence was found which may justify a different diagnostic or therapeutic approach with respect to female breast cancer.

The role of fine needle aspiration cytology in the differential diagnosis of suspected breast cancer local recurrences.

The authors report on 228 cases of suspected breast cancer local recurrences studied by fine needle aspiration cytology (FNAC). The nature (malignant = 133, benign = 95) of suspected lesions was assessed on histology (no. = 46) or according to unequivocal follow-up (no. = 182). Inadequacy rate was 0.20, 0.09 or 0.35 in total, cancer or benign cases, respectively, and was particularly high (0.50) for benign chest wall lesions. Accuracy was determined on adequate smears; dubious reports were assumed as positive. Sensitivity and specificity were 0.96 and 0.97, respectively. The routine use of FNAC is recommended since it helps in the differential diagnosis of suspicious cases and may bypass surgical biopsy of positive cases not eligible for surgical treatment.

Risk of breast cancer subsequent to proven gross cystic disease.

3809 women in whom breast cysts were aspirated were followed up to evaluate the observed/expected ratio of subsequent breast cancer. Breast cancer at cyst aspiration was excluded by physical examination and mammography. The first year of follow-up was censored to avoid a prevalence screening effect. Subsequent breast cancers were found either directly or by means of a cancer registry which also provided the expected age and residence specific incidence rates. The number of expected cancers was assessed in person-years (15,915 in the total series). The observed/expected subsequent breast cancer ratio was 1.77 (34/19.15; 95% confidence interval 1.23-2.48, P less than 0.05). The presence of gross cysts was associated with a moderately though significantly increased risk of subsequent breast cancer. Increased surveillance in such patients is not justified.

Referral policy and positive predictive value of call for surgical biopsy in the Florence Breast Cancer Screening Program.

The authors evaluate the referral rates and the predictive value (PV) of call for diagnostic work up or biopsy in a population based breast cancer screening program in the 1979-1986 period. The presence of mammographic abnormalities either benign or suspicious proved to be the only reliable referral criterion (recall rate = 7.9%, recall PV = 3.8%, biopsy call PV = 39%). When mammography was normal the presence of breast complaints other than pain or of a radiologically dense breast were aspecific referral criteria, and since the latter was abandoned, (a) referral rates dropped especially in younger women, (b) referral or biopsy PV improved, whereas (c) cancer detection rate was almost unaffected. Younger age was associated with higher referral rates and with lower PV of both referral or biopsy. Whenever comparison with previous examination was possible, mammography accuracy was higher; this explains the decrease in referral rates and the increased predictivity observed at further rounds with respect to first screening round.

Colposcopic survey of Papanicolaou test-negative cases with hyperkeratosis or parakeratosis.

A colposcopic survey was performed in 269 consecutive women with negative cytology showing hyperkeratosis or parakeratosis. A colposcopy-guided biopsy specimen of cervical abnormalities was taken in 88 cases, and human papillomavirus infection (HPV) was detected histologically in 25 cases. No cervical intraepithelial neoplasia (CIN) was detected. The detection rate of HPV was not significantly different from that observed in a consecutive series of 1073 Papanicolaou test-negative subjects self-referred for colposcopy. Colposcopic screening of subjects showing hyperkeratosis or parakeratosis with otherwise negative smears is not recommended because it does not allow detection of cytologically false-negative CIN.

In situ ductal carcinoma of the breast--analysis of clinical presentation and outcome in 156 consecutive cases.

We report on 156 consecutive cases of in situ ductal carcinoma (DCIS) of the breast observed from 1968 to 1988. The relative frequency of DCIS was much higher in screened, with respect to self-referred, women and a significant association of DCIS with younger age was observed. The combined use of mammography and physical examination identified 138 of 156 total DCIS cases as suspicious. Mammography, physical examination or cytology (of nipple discharge or needle aspirate) were the only tests to provide suspicious evidence in 35, 22 and four cases respectively. DCIS was a relatively unexpected surgical finding in 13 apparently benign cases. Different surgical options were recorded in the study period but a temporal trend in favour of conservative surgery was evident. Subsequent ipsilateral or contralateral breast cancer was recorded in seven and six cases respectively. Death from breast cancer occurred in five cases, all of whom had contralateral or subsequent ipsilateral infiltrating cancer. This figure confirms the high curability of DCIS if local control is achieved.

Prognosis of nonpalpable infiltrating carcinoma of the breast.

A consecutive series of 185 instances of histologically confirmed nonpalpable infiltrating carcinoma of the breast is presented. Histologic nodal involvement was found in 12 per cent and was dependent on the size of the tumor. Conservative surgical treatment was the predominant method used during the study period. The ten year over-all survival was studied and compared with that of 4,217 instances of palpable carcinoma of the breast observed during the same period. The ten year survival rates were, by far, better for nonpalpable (94 per cent) than for palpable carcinomas (65 per cent). A better prognosis for nonpalpable carcinomas was confirmed also by multivariate analysis (Cox) with adjustment for potential confounders, such as age, stage or nodal involvement. The possible confounding effect of over diagnosis and length or lead time bias is discussed. Although this difference in survival might be partially explained by the aforementioned confounders, the chance of increasing life expectancy and conservative surgical treatment encourages preclinical detection of carcinoma of the breast.

Tumor size and prognosis of breast cancer with negative axillary nodes.

A report on 1877 consecutive node negative (N-) breast cancer cases is presented in which the prognostic value of the main clinico-pathologic features is evaluated. Tumor size (and UICC-TNM T category) and lobular infiltrating histologic type were significantly associated with a more favorable prognosis whereas no association was found for patient age, tumor site and number of examined axillary nodes. However tumor size (and T category) is not a very accurate prognostic predictor (71% of all recurrences observed occurred in cases with tumor diameter of more than 20 mm, which represented 58% of the total series), although its efficiency seems almost as good as that of other more recent prognostic predictors such as estrogen receptor content or labeling index. None of the prognostic predictors currently available, including tumor size, seems sufficiently specific and they do not allow for a reliable selection of high risk N-patients for adjuvant treatment.

Fine needle aspiration cytology and breast cancer diagnosis.

The authors report on 315 histologically confirmed consecutive breast cancer (BC) cases undergoing fine needle aspiration cytology (FNAC). Inadequate smears were infrequent (7%), particularly when reaspiration of inadequate cases was employed (1-2%). FNAC suspected BC in 81% of the total or 88% of adequate smears. Univariate and multivariate (Cox's model) analyses showed no correlation between inadequacy or suspect/positive FNAC rate and patient age, T category or histologic type. Differences in the inadequacy and suspect/positive rate were recorded among 30 operators (surgeons, oncologists, radiologists) performing the sampling, but the average results were consistent with literature reports. FNAC was found to be a useful diagnostic tool for BC diagnosis, and proper training of the highest number of operators is recommended to allow the widest diffusion of this diagnostic technique.

Telethermography and breast cancer risk prediction.

The authors report on 4,624 noncancer women classified by telethermography (TH1-2 vs TH3) and followed for an average of 6.6 years (range, 2-12). Breast cancer occurring beyond the sixth month from TH were recorded according to a Cancer Registry, and the association between breast cancer incidence and thermographic class or patient age was evaluated. Univariate analysis showed a significant association of age and thermography with further cancer incidence, but multivariate analysis (Cox's model) confirmed a significant association only for age. Thermography (TH3) showed a nonsignificant odds ratio of 1.6 with respect to TH1-2 cases. Thus thermography did not show any practical role as a breast cancer risk indicator. Possible biases affecting previous reports suggesting the use of thermography as a breast cancer risk indicator are discussed.

"T" category and operable breast cancer prognosis.

The authors report on 4,034 consecutively operated breast cancer cases, evaluating the correlation between clinical T category and long term survival. Age and pathologic nodal status were also considered as independent prognostic factors. Univeriate and multivariate (Cox's) analysis confirmed N status as the most powerful single prognostic indicator and did not reveal any prognostic correlation with age. T category was a strong prognostic indicator, independently of N status, the 10 year overall survival of T1, T2 or T3-4 cases being 0.86, 0.76 and 0.73 in N- and 0.73, 0.56 and 0.35 in N+ subgroups respectively. T category should be carefully considered not only in deciding the extent of surgical excision but also in planning adjuvant postoperative treatment.

Chest X-ray survey in the follow-up of breast cancer patients.

The authors report on 182 cases of intrathoracic metastases (ITM = lung, pleura or mediastinum) observed as first single recurrences in the course of the follow-up of patients treated for primary breast cancer. ITM were detected on standard two-views chest X-ray (CXR) at regular follow-up visits and in absence of subjective symptoms (102 A cases) or in the interval between two consecutive planned controls because of the onset of subjective symptoms (80 S cases). The average disease-free interval since primary treatment was significantly shorter in A with respect to S cases (40.3 vs. 28.5 months, P less than 0.001) as a consequence of the early detection achieved by CXR survey. On the contrary, prognosis was not influenced by ITM early diagnosis as the 10-year survival since primary treatment did not differ significantly between A or S cases (12% vs. 10%, P = 0.68). Results were confirmed on multivariate (Cox's) analysis, adjusting for potential confounders such as age or nodal status. Periodic CXR survey looks a very questionable policy as it does not seem to have any favourable impact on prognosis. Its routine use in breast cancer patients should thus be carefully reconsidered.
