Abstract
BACKGROUND AND PURPOSE To analyse the outcome, the treatment related side effects, the prognostic significance of clinical parameters in a group of patients with rectal cancer receiving postoperative radiotherapy after radical resection. MATERIALS AND METHODS From 1980 to 1990 148 consecutive patients with rectal carcinoma stage B2-B3 or C1-C2-C3 were treated with postoperative radiotherapy after radical surgery. All patients received 50 Gy in 25 sessions in 5 weeks. In 42 a "flash' dose of 5 Gy was also given within 24 h before surgery. Median follow up was 8.1 years. RESULTS At 5 years the overall survival was 54%, the determined (cancer specific) survival 61%, the local recurrence-free survival 88%. The influence of stage, histotype, distance from anal margin, type of surgery, number of involved nodes and flash dose were analysed. Overall and determined survival and distant metastasis rate were significantly influenced (P < 0.005) by the pathological stage. Patients with more than 3 involved nodes presented a significantly lower determined survival (P < 0.001) and a higher distant relapse rate (P < 0.005) than those with 3 or less involved nodes. A higher determined survival (P < 0.01) was also found in patients receiving the preoperative "flash'; this group was however unbalanced in respect to the relative number of cases with 3 or less involved nodes. The incidence of major side effects requiring surgery or hospitalization for medical treatment was 35% before 1985 and 12% thereafter. The systematic use of small bowel visualization during simulation and the discontinuation of the flash dose were the main modifications introduced in the second period. As a consequence of the small bowel visualization the size of lateral fields was slightly reduced and some patients were excluded from the treatment. CONCLUSIONS Value of postoperative radiotherapy to decrease the incidence of local recurrence was confirmed in this retrospective study; the incidence of side effects was however considerable and did not support the addition of chemotherapy as advised by the NIH consensus meeting. Our policy was therefore moved to preoperative irradiation whose combination with chemotherapy was recently reported to be better tolerated and highly effective.

Abstract
Frozen section (FS) diagnosis was routinely performed in a large series of nonpalpable breast lesions from 1977 through 1991. The original FS diagnoses of 672 patients were classified in four categories (1 = benign lesion, 2 = in situ carcinoma, 3 = invasive carcinoma, 4 = deferred diagnosis) and compared with the diagnoses obtained at review of the permanent paraffin sections to estimate the accuracy of FS. A review of the mammographic pattern of the lesion was also performed. Frozen section diagnostic conclusion was deferred to permanent paraffin sections in only 22 cases (3.3%). Benign or malignant (grouping in situ and invasive carcinomas) FS diagnoses were accurate in 623 of 650 cases (95.8%). Overall, the prevalence of malignant lesions was 44.8% with a benign/malignant ratio of 1.2. The diagnosis was modified on the basis of permanent sections in 27 cases (4.2%) with three false positives and 24 false negatives. Sensitivity and specificity of FS diagnoses were 91.7 and 99.2%, respectively. When the comparison between FS and histologic diagnoses was analyzed according to the mammographic pattern, sensitivity among patients with microcalcifications as the only alteration was lower (88.8%) than among patients with opacities (94.9%). On the basis of these results, FS is to be considered a feasible and reliable diagnostic procedure in nonpalpable breast lesions, particularly in cases excised because of a mammographic opacity that is identifiable on gross examination of the surgical specimen.

Abstract
We report on 1182 consecutive histologically confirmed non-palpable breast lesions detected by mammography (infiltrating carcinoma 427, in situ carcinoma 121, benign 634). The proportion of cancer cases varied according to age (< 50 years = 33%; 50-59 years = 46%; > 59 years = 63%), mammographic pattern (regular opacities = 8%, parenchymal distortions = 20%, isolated calcifications = 42%, irregular opacities = 62%, stellate opacities = 73%), and calendar period (1970-1985 = 29%, 1986-1989 = 56%; 1990-1992 = 69%). A sharp decrease of the benign/malignant biopsy ratio was evident after routine fine-needle aspiration cytology (sonography-guided or stereotaxic) was introduced in 1986. The independent significant association of cancer frequency to age, calendar period and mammographic pattern was confirmed by multivariate analysis. A significant trend over time in favour of conservative surgery was also observed for cancer cases (1970-1979 = 6%, 1980-1985 = 41%, 1986-1992 = 83%). Among invasive cancers, node involvement was observed in 11.5% of cases, being associated with tumour size (pT1a = 0%, pT1b = 7%, pT1c = 13%, pT2a = 33%). Five-, ten- and fifteen-year overall survivals of invasive cancers were 98.1, 95.7 and 87.3%, respectively.

Abstract
In breast cancer the study of prognostic factors has been well developed during last years and many biologic and biochemical parameters have been analyzed. Cell kinetics parameters demonstrated the capability to select patients with different risk of evolution of the neoplasia and in some cases treatment protocols are established by means of proliferation rate. The present study deals with the determination of Thymidine Labelling Index in breast tumors mostly T1-T2 with negative lymph nodes. Results demonstrated that the proliferative activity is higher in younger patients, in T2 cancers compared to T1, and in ductal infiltrating forms compared to the other more frequent histotypes. A significant correlation has been observed between TLI and nuclear grade. The preliminary analysis of the prognostic value of TLI has been two performed using an experimental cut off that is able to discriminate groups of patients with overall survival rate of 67% and 88%, depending on the different proliferative activity of the tumor.

Abstract
BACKGROUND The prognostic value of proliferating cell nuclear antigen (PCNA) has been demonstrated in recent studies of human tumors including breast cancer. METHODS PCNA immunoreactivity was assessed retrospectively in a consecutive series of 173 lymph node-negative primary breast cancer cases. The PCNA grade was determined according to estimated quartiles of nuclear immunostaining, and its association to disease-free and overall survival was studied. RESULTS PCNA grade was associated significantly with nuclear grade. On univariate analysis, PCNA grade was associated significantly with both 5-year relapse-free survival rate (Grades 1-2 = 78%; Grades 3-4 = 52%; P = 0.0117) and overall survival. On multivariate analysis, T category and PCNA were associated independently and significantly with both relapse-free and overall survival. Nevertheless, the magnitude of the association of PCNA grade to prognosis was low (relative risk of recurrence in patients with PCNA Grades 3-4 versus Grades 1-2 = 2.13), and only 24% of all relapses or 28.8% of all cancer deaths observed at 5 years occurred in patients with PCNA Grades 3-4. CONCLUSIONS The predictive value of the relationship of PCNA grade to prognosis was too low to be of value as an independent prognostic indicator.

Abstract
The prognostic value of c-erbB-2 oncogene expression was studied retrospectively in a consecutive series of 230 node negative breast cancers, followed-up for at least 7 years after primary treatment. The expression of c-erbB-2 oncoprotein was determined on formalin-fixed paraffin-embedded tissue, using a monoclonal anti-c-erbB-2 antibody by the avidin-biotin immunoperoxidase method. Positive immunostaining was observed in 20.9% of cases, whereas strong diffuse positivity was recorded only in 8.7% of cases. C-erbB-2 gene product showed no association to T category or nuclear grade. A significant association of c-erbB-2 expression to prognosis was observed only for cases showing a strong diffuse immunostaining, but such an association was no longer statistically significant at multivariate analysis adjusting for other prognostic factors such as T category and nuclear grading. C-erbB-2 expression is of no value to predict the clinical course of node negative patients in the current practice.

Abstract
A series of 59 phyllodes tumors of the breast was retrospectively reviewed (average follow-up = 3.9 years). Clinical features (age, size of tumor) and diagnostic tests (palpation, mammography, sonography and cytology) were found to be inaccurate in predicting benign (n = 22), borderline (n = 12) or malignant (n = 25) histological type. Limited surgery was associated with a relatively high proportion of local recurrence (enucleation/enucleoresection = 3/5, wide resection = 12/30) compared with mastectomy (2/24). No significant association was observed between the probability of local recurrence and patient's age, histological type or lesion size. Although the study confirms that limited surgery may cure phyllodes tumor, careful follow-up of all patients is needed, since no reliable risk factors for recurrence are available. In malignant cases, axillary node involvement was nil and distant metastases were infrequently observed (3/25). Axillary dissection and search for asymptomatic metastases is not recommended.

Abstract
The aim was to review a series of 183 intraductal breast cancer to define the diagnostic features and therapeutic outcome. Patients' average age was 54 years. Diagnostic procedures employed were clinical examination, mammography in 173 cases and fine-needle aspiration cytology in 98 cases. The sensitivity of clinical examination was 0.61, of mammography 0.74, of fine needle aspiration cytology 0.70. The sensitivity of clinical examination and mammography associated was 0.93. The surgical options adopted were: conservative surgery 80 cases, mastectomy 103 cases. Conservative surgery was followed by breast irradiation in 34 cases. Axillary dissection was performed in 122. 97 cases have been reviewed histologically. 60% of ductal carcinoma in situ (DCIS) were multifocal and 22% multicentric. Local recurrence, all infiltrating, occurred in the same breast after conservative surgery in 8 cases, 3 of which had received postoperative radiotherapy, and in 3 patients after mastectomy. Contralateral breast cancer was recorded in 13 cases, being synchronous in 4 (infiltrating in 3, DCIS in 1) and metachronous in 8 (all infiltrating). 3 patients died of breast cancer. The present series confirms the risk of ipsilateral cancer recurrence after conservative surgery but there are no significant differences relating to mammographic pattern, size, histological type, margin involvement and radiotherapy.

Abstract
CA 15-3 and MCA assays were tested in 103 operable patients (preoperative determination) and 100 patients with advanced breast cancer. Normal CA 15-3 and MCA values were determined in a series of 68 healthy women. The negative/positive cut-off was set at 28.8 U/ml and 15.5 U/ml respectively for CA 15-3 and MCA (mean value + 2SD). Results were analyzed in the two groups and with respect to T and N pathological categories in the preoperative series. In pT1 (59 pts), pT2 (30 pts), pT3 + pT4 (14 pts), pNO (58 pts), pN1 (45 pts) and overall preoperative series CA 15-3 and MCA sensitivities were respectively 25%, 40%, 57%, 22%, 42%, 30% and 27%, 30%, 35%, 21%, 33%, 26%. In the patients affected by widespread disease, sensitivity was 92% and 80% for CA 15-3 and MCA. Results were significantly different among normal, preoperative and advanced patients (P less than 0.05). Our results suggest that CA 15-3 and MCA levels are correlated with the tumor mass. Nevertheless, the low sensitivity in pT1 and pNO cases indicates that these two assays have no role in the diagnosis of early breast cancer. In the advanced patients, too, the results can be questioned: in the present study, in fact, recurrent cases were characterized by gross disease with multiple site involvement and cannot be considered as an example of early diagnosis of breast cancer recurrence.

Abstract
Estrogen receptors (ER), progesterone receptors (PR) and alkaline phosphatases (AP) were measured in 150 tumors from patients who underwent mastectomy for primary breast cancer. The percentage of ER positive samples was inversely related to the AP activity ranging from 88.9% in low activity samples (less than 30 U/mg prot.) down to 30.6% in the high activity ones (greater than 400 U/mg prot.). When considering only ER positive samples, the ER content was inversely related to the AP activity. This could not be demonstrated for PR. Therefore, the authors suggest the hypothesis that in human breast cancer, the AP may play a role in the dephosphorylation of the ER molecule and in the consequent modulation of its binding capability.

Abstract
Alternative splicing of the c-erbA alpha gene transcript generates mRNAs encoding a thyroid hormone (T3) receptor (alpha 1) and a non-T3-binding variant (alpha 2). Also encoded at this genomic locus is Rev-ErbA alpha (Rev), a non-T3-binding member of the T3/steroid hormone receptor family. The DNA strand coding for Rev is opposite of that encoding the c-erbA alpha proteins, such that bidirectional transcription is required to generate the Rev and alpha 2 mRNAs. We have used cycloheximide as a tool for studying the regulation of gene expression from this complex genomic locus. In 235-1 cells cycloheximide treatment increased Rev mRNA levels by 50-100-fold. The effect was detectable after a 1-2-h incubation with 20 micrograms/ml cycloheximide and maximal at 24 h. The cycloheximide-induced increase in Rev gene expression was due to inhibition of protein synthesis since anisomycin caused a similar induction of Rev mRNA. Nuclear run-on assays revealed an approximately 10-fold increase in the transcriptional rate of the Rev gene during cycloheximide treatment. In addition, cycloheximide stabilized the Rev mRNA, as evidenced by half-life determinations in the presence of actinomycin D (5 ng/ml). Thus, labile proteins repress basal Rev gene expression both transcriptionally and post-transcriptionally. Cycloheximide treatment also increased alpha 1 and decreased alpha 2 mRNA levels, with the alpha 1/alpha 2 ratio increasing approximately 10-fold. Interestingly, however, these effects appeared not to be due to changes in rates of transcription or degradation of either mRNA. A likely alternative, given the structure of the c-erbA alpha gene, is that inhibition of protein synthesis resulted in a change in the c-erbA alpha splicing pattern. We hypothesize that this may be causally related to the accumulation of Rev mRNA (or the nascent Rev gene transcript), which could inhibit splicing to alpha 2 by hybridizing to complementary sequences, favoring alpha 1 mRNA production. Since alpha 1 is a T3 receptor whereas alpha 2 is an inhibitor of T3 action, such changes could influence target cell responsiveness to T3.

Abstract
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.

Abstract
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.

Sixty-four consecutive patients who had undergone curative resection for colorectal carcinoma were studied prospectively to evaluate the roles of sequential CEA determinations and independent instrumental follow-up in the early detection of resectable recurrences. Fifty-two of these patients also were submitted to sequential determinations of other tumor antigens: TPA (tissue polypeptide antigen) and Ca 19-9 (colon cancer antigen detected with a monoclonal antibody), for a retrospective evaluation of their utility as markers of recurrent tumors. Twenty-two recurrences were detected in a period ranging from 12 to 72 months (median, 47 months). CEA was the best predictor of recurrence (sensitivity, 90 percent) when compared with the other two markers (TPA sensitivity, 60 percent; Ca 19-9 sensitivity, 20 percent). When compared with the instrumental or biochemical examinations of the follow-up, CEA was still the most sensitive indicator of relapse although the specificity was quite low (78 percent) if minimal significative increases were considered. History and physical examination were more useful than CEA in detecting local recurrences in rectal cancer where the preoperative CEA level was low. A few second-look explorations based solely on small CEA increases failed to demonstrate recurrence or revealed peritoneal carcinomatosis. Selected second-look surgery based on demonstrated recurrences resulted in a resectability rate of 57 percent. A follow-up program based on frequent CEA assays, history, and physical examinations, including rectal, vaginal, and perineal exploration, is proposed. Extensive instrumental investigations should follow when a minimal significative CEA rise is observed, or when history and physical examinations suggest a possible recurrence. Second-look surgery should be evaluated after confirmed or highly suspected diagnosis of recurrence, on the basis of instrumental or clinical examinations.

Abstract
The authors measured estrogen receptors, and polyamine (putrescine, spermidine and spermine) in breast tumors from patients (n = 23) who had received tamoxifen for a few days (5-10) before surgery. Women undergoing mastectomy without any preoperatory treatment were selected as the control group (n = 44). As already reported about in vitro experiments, the treatment resulted in a significant lowering of the spermidine to spermine ratio. Such a modification was larger in the ER positive tumors then in the ER negative ones and it seems to be related to the regression process of the drug-responsive tumors. On the basis of the experimental data the authors suggest the development of a in vivo tamoxifen-sensitivity test.

Abstract
Thirty-seven (4.1%) cases of nodal metastases skipping the first level are reported in a consecutive series of 912 breast cancer axillary dissections including 392 N+ cases. First level nodes examination is sufficiently accurate in assessing the quality of nodal status (negative or positive) but not the extent of nodal involvement (number of involved nodes).

Abstract
The authors report a series of 97 cases of phlogistic-like process of the breast. Clinical and radiological signs and criteria of differential diagnosis between benign phlogosis and cancer are investigated. The location in the areolar/periareolar region, the presence of fever, and the radiological evidence of limited skin thickening were the features more significantly correlated with benign phlogosis, while cancer should be suspected in the case of lesions located in the upper-outer quadrant and in presence of a diffuse skin thickening at radiological examination. These diagnostic criteria seem particularly useful since the typical clinical or radiological signs of cancer are present only in 50 % of cancer cases. The cytological examination of nipple discharge or needle aspiration fluid is of particular help: no false positive or negative cases were observed in a series of 42 examined patients.
