The clinico-pathological findings are presented in a case of Peutz-Jeghers syndrome associated with a bilateral mammary invasive ductal carcinoma, a well-differentiated mucinous adenocarcinoma of the cervix and microscopic, bilateral ovarian sex cord tumors with annular tubules. The sex cord tumor with annular tubules was described in 1970 by SCULLY, who recognized its striking association with the Peutz-Jeghers syndrome. Two cases of adenocarcinoma of the cervix and another case of uterine adenocarcinoma of unspecified localization associated with Peutz-Jeghers syndrome were found in the literature. It is possible that women with Peutz-Jeghers syndrome run an increased risk of developing adenocarcinoma of the uterine cervix.

A nationwide multicenter joint study was undertaken to investigate the clinicopathologic characteristics of invasive ductal carcinoma of the breast with a predominant intraductal component, a diagnostic entity proposed in the histologic typing of breast tumors by the World Health Organization in 1981. A total of 368 tumors, of which 218 were studied pathologically between 1983 and 1987 and 150 between 1971 and 1977, were accumulated for the present study from seven medical institutes in Japan. The incidence of such types of tumor was higher in the latter period than in the former, as was that of pure intraductal carcinomas. Seventy of the 368 tumors displayed metastatic nodal involvement and nine tumor deaths were observed from 150 tumors followed up for over 10 years following radical mastectomy, the overall quantity of the extraductal stromal invasion clearly acting on lymph node metastases and patients' outcome. We consider a total stromal invasion of greater than 5 mm to be critical in the prognosis of patients with tumor of this type.

Between 1977 and 1986, 879 patients with Stage I and II breast cancer underwent excisional biopsy, axillary dissection, and radiation. Median follow-up was 61 months (range 2-159 months). The patients were divided into seven groups based on histologic subtype: (a) 368 patients with both infiltrating and intraductal ductal carcinoma, (b) 389 infiltrating ductal carcinoma, (c) 41 infiltrating lobular carcinoma, (d) 23 combined infiltrating ductal and lobular carcinoma, (e) 28 medullary carcinoma, (f) 12 colloid carcinomas, and (g) 18 tubular carcinomas. Significant differences in clinical T status, pathologic nodal involvement, administration of chemotherapy, estrogen receptor positivity, progesterone receptor positivity, and age were observed between some histologic subgroups. Tubular and colloid carcinomas were more likely to present with T1 lesions, hormone receptor positivity, and node negative status than the other histologic subtypes. Most medullary carcinomas were hormone receptor negative and were younger than 50 years old. Infiltrating lobular carcinoma patients were more frequently lymph node negative, older, node negative, and estrogen receptor positive compared to the other groups (except for tubular and colloid patients). Differences in the administration of chemotherapy primarily reflected differences in lymph node involvement. Location of the tumor in the breast and menopausal status did not correlate with histologic subtype. There were no significant differences in 5-year actuarial overall survival, cause-specific survival, or relapse-free survival between the histologic categories. In addition, patterns of first failure were not significantly different among the histologic groups in terms of local-only first failure, any local component of first failure, regional-only first failure, or any regional component of first failure. There was, however, a difference among the seven groups in distant metastasis-only at first failure with invasive ductal carcinomas having the highest rate. Despite this difference, histologic subtype had no impact on survival. The site of in-breast failure relative to the location of the original tumor was not significantly different between groups. The histologic subtype of invasive breast cancer is not an independent risk factor in predicting survival or pattern of failure. Conservative surgery and radiation therapy is effective treatment of ductal, lobular, medullary, colloid, and tubular invasive breast cancer.

It is reported upon two patients who were presented to us to evaluate suspicious tumors of the breast: A 64-year-old patient had very painful tumors in both breasts measuring four centimeters in diameter with additional eczematous lesion of the left mamilla, which has developed within the last weeks. For many years she suffered of a pseudoxanthoma elasticum (PXE) of the skin combined with arterial occlusion disease. Histologically these tumors showed necrosis and typical signs of PXE, which is to our knowledge the first case reported in literature. A 79-year-old patient showed an inverted eczematous nipple, combined with a retromamillar painless tumor of the left breast. The histology was Paget's disease with an underlaying ductal carcinoma. --The clinical picture and the diagnosis are presented, followed by the discussion and the differential diagnosis.

Mucinous ductal ectasia is recognized as a premalignant disease. Recently, we have encountered a patient with a mucin-producing neoplasm of the pancreas, who had been under periodic observation for chronic pancreatitis for 7 years prior to diagnosis of carcinoma and surgery. A 54-year-old male who had been investigated with US, CT and ERCP for chronic pancreatitis developed a mucin-producing ductal carcinoma of the pancreas. In this case a series of US and ERCP images obtained during the 7-year period had demonstrated insidious growth of the tumor. Pancreaticoduodenectomy was carried out, and the histopathological diagnosis was mucin-producing adenocarcinoma of the pancreas. The patient has been well and has suffered no recurrence for 2 years after surgery.

Prolactin plays a key role in the regulation and growth of mammary cells, and influences tumor promotion. We have shown that chronic energy restriction intake depresses prolactin levels, inhibits production of MMTV proviral DNA and proto-oncogene expression in mammary glands and prevents development of mammary tumors. Since the expression and proto-oncogene activation of MMTV are regulated by promoter/enhancer elements within its long terminal repeat (LTR), in the present study we used a chloramphenicol acetyl transferase (CAT) reporter gene system and gene transfection methods to study the effect of prolactin on MMTV LTR using a human ductal carcinoma cell line T47D stably or transiently transfected with a plasmid consisting of the LTR upstream of CAT gene. Human prolactin or dexamethasone induced, respectively, a 2-fold or 6-fold increase in CAT activity compared with background CAT activity in the absence of hormones. However, the combination of human prolactin and dexamethasone strongly enhanced (20-fold) induction of the LTR compared with the control. Human prolactin also showed a synergistic effect with progesterone on LTR induction. Both LTR and CAT genes needed to be linked for induction of CAT activity by prolactin and dexamethasone. Our results indicate that human prolactin can act synergistically with steroid hormones to regulate MMTV LTR-directed gene expression in transfected T47D cells.

The association of c-erbB-2 gene amplification product (p185) with histologic tumor type in 100 patients with primary breast cancer was determined. In 49 patients with infiltrating ductal carcinoma p185 detection was correlated with histologic findings (tumor grade, lymphnode status, receptor status). Strong positive staining for p185 protein was found in 10 patients (20%) with infiltrating ductal breast carcinoma and correlated with complete negative estrogen/progesterone receptor status and with histologic grade G3. There was neither an association with lymphnode involvement nor was there any to negative estrogen and progesterone receptor status alone. At present, we cannot say whether or not there is a correlation between the degree of c-erbB-2 gene amplification and prognosis. Follow-up studies are necessary to determine whether c-erbB-2 gene amplification allows definition of a specific subset of women who could benefit from adjuvant therapy.

Benign and malignant diseases of the pancreas were compared with nuclear DNA content by flow cytometry, and the relationship between nuclear DNA content and histopathological findings was studied in ductal carcinoma of the pancreas. The nuclear DNA content in the malignant disease was higher than that in the benign disease. No significant correlation between nuclear DNA content and histopathological findings was observed in ductal carcinoma of the pancreas. A tendency for the nuclear DNA content to increase in proportion to the tumor size and the stage was, however, observed. Study of the nuclear DNA content is believed to be an effective adjuvant modality in differential diagnosis between benign and malignant disease of the pancreas.

A total of 257 autopsy cases of pancreatic carcinoma, including 160 male and 97 female cases with an average age of 68.2 years, were divided into an aged group (70 years or older, 136 cases) and a control group (younger than 70 years, 121 cases), and their respective clinicopathological features were compared. The male to female ratio was 1.2:1 in the aged group and 2.6:1 in the control group. In both groups, abdominal pain was noted in about one-third of the cases as the primary symptom, followed by appetite loss and icterus. Concerning the primary symptoms, the two groups did not differ from each other. The rate of surgical resection was higher in the control group (24.0%) than the aged group (10.3%). Mean survival times were similar in both groups (5.71 months for the aged group and 6.01 for the control group). Intrapancreatic location of the tumor showed similar tendencies in both groups. However, cancer of the head of the pancreas was 2.3 times more common than body/tail cancer in cases aged 80 or more. Approximately 90% of the cases were diagnosed as ductal carcinoma by histological examination. The degree of differentiation was similar in both groups, but the well differentiated type was somewhat predominant in cases 80 years or older. Metastasis or direct invasion was noted to the liver, peritoneum and lung in this order in both groups. Liver and lymph node metastasis were less frequent in cases 80 years or older. Multiple primary cancers were noted in 8.8% of the aged group and 9.1% of the control.(ABSTRACT TRUNCATED AT 250 WORDS)

A 94 year old man with an invasive ductal carcinoma of the breast (T4N2M1, stage IV), underwent a modified radical mastectomy to improve his quality of life. The estrogen receptor status of both the breast tumor and the metastatic axillar lymph nodes was high. Immunohistochemical staining for epidermal growth factor, epidermal growth factor receptor, or c-erbB-2 protein was negative. The patient received only tamoxifen continuously for 3 months, and later apparently showed a complete remission. Therefore, in advanced male breast cancer with a high estrogen receptor status, operation in conjunction with hormone therapy may lead to a favorable result in some cases.
