From 1975 to 1985 we review 12 cases of mucinous carcinoma of the breast in the "Hospital Civil de Guadalajara" and we found: one in the male sex and 11 in female. The mean age was 53 years 4 (36.3%) were nulliparas, the period between the star of symptomatology and the treatment was of 3 months to 6 years, 50% were in the upperexternal quadrant, the size was of 2 to 20 cm; 5 were pure mucinous and 7 mixed (with ductal invasive carcinoma), metastasis were presenting 9 patients and the treatment utilized in the majority of the cases was the radical mastectomy.

Monoclonal antibodies (Mabs) against human ovarian mucinous and serous carcinoma were obtained by the Mab technique. Their reactivities against human tumors were tested by indirect immunofluorescence. One of the Mabs, named 4C7, derived from the spleen cells of mice immunized with mucinous carcinoma line OVA-1, reacted to ovarian mucinous carcinoma, endometrioid carcinoma, and mesonephroid carcinoma but did not react to ovarian serous carcinoma. Another Mab, 3C2, obtained from the spleen cells of mice immunized with serous carcinoma line HOC-21, reacted to serous carcinoma and endometrioid carcinoma of ovary, but never reacted to mucinous carcinoma or mesonephroid carcinoma. Neither of the Mabs reacted to other types of ovarian carcinomas such as undifferentiated carcinoma, dysgerminoma, endodermal sinus tumor, and malignant teratoma of ovary, and also did not react to any benign ovarian tumors or other normal human tissues. Both Mabs 3C2 and 4C7 had no reactivity to carcinoma of other organs such as stomach, colon, lung, lymphoid system, and kidney and also did not react to human lymphocytic or carcinoembryonic antigen as confirmed by using many human cell lines and surgically resected samples. Since the cross-reactivities of these Mabs were limited within the ovarian epithelial carcinomas, it is suggested that two distinct epitopes are expressed on the ovarian epithelial carcinomas. One epitope, identified by Mab 4C7, is expressed only on mucinous carcinoma, endometrioid carcinoma, and mesonephroid carcinoma, while the epitope, identified by Mab 3C2, appears only on serous and endometrioid carcinoma.

The murine monoclonal antibody (Mab) against human common epithelial ovarian carcinoma, CF511, was generated by immunising mice with human fetal tissue extract from early first trimester, followed by booster injection of an ovarian cancer cell line. Mab CF511 recognised the 600 kDa sialylated glycoprotein as different from previously known tumour associated-marker antigens. Distribution of the Mab CF511-recognised antigen (CF511 antigen) in various tissues and sera was investigated. In immunohistochemical analysis, Mab CF511 reacted strongly with tumour cells of ovarian serous, clear cell, endometrioid and undifferentiated carcinoma and partially with those of mucinous carcinoma. Mab CF511 also reacted with breast carcinoma as well as lung carcinoma. In normal tissues, Mab CF511 cross-reacted with only five tissues, namely lung, breast, thyroid gland, fallopian tube and uterus. Serum levels of CF511 antigen were tested by ELISA inhibition using Mab CF511. This assay showed the circulating CF511 antigen levels to be elevated in 25 of 36 sera from patients with various clinical stages of common epithelial ovarian carcinoma compared to three of 47 and three of 111 sera from patients with other benign gynaecological diseases, including ovarian cysts, uterine fibroids with or without endometriosis and normal healthy subjects, respectively. For the relation between antigen levels and clinical stages of common epithelial ovarian carcinoma, greater than 34.0% ELISA inhibition was detected in 100% of patients with advanced stages (FIGO III and IV) compared with in 35.3% with early stages (FIGO I and II) patients. While patients with breast carcinoma (100%) and lung carcinoma (100%) also had elevated circulating CF511 antigen levels, patients with hepatoma, colorectal carcinoma and gastric carcinoma had no detectable elevation of antigen. Although the test showed a high degree of specificity, the detection of an elevated CF511 antigen level would not be so helpful in distinguishing patients with ovarian carcinoma from those with either breast carcinoma or lung carcinoma. These data suggest that CF511 antigen is a useful new ovarian tumour marker for diagnosis and management of the disease.

The antibody against a molecular weight 15,000 protein isolated from the breast cyst fluid (GCDFP-15) was applied to tissue from cutaneous tumors, especially to sweat gland tumors. This protein was purified from the breast cyst fluid; antisera was prepared in rabbits. Ninety six cases of cutaneous tumors were stained by the PAP method. Apocrine hydrocystoma, syringocystadenoma papilliferum, so-called mixed tumor of the skin, extramammary Paget's disease, microcystic adnexal carcinoma, and mucinous carcinoma of the skin were positively stained. Eccrine poroma, eccrine spiradenoma, syringoma, eccrine hydrocystoma, papillary eccrine adenoma, adenoid type of basalioma were negative. These observations indicate that the positively stained tumors have functioning seromucous cells, which are characteristic of apocrine gland cells and eccrine dark cells in the skin.

During a seven year period ending in 1984, the Calvados Registry of Digestive Tract Tumors (France) recorded 1446 cases of colorectal cancer. The sex-ratio, age, and histologic type were studied with respect to location. From cecum to rectum, the sex-ratio varied from 1 to 1.9. Average age at diagnosis varied between 67.5 and 72.6 years for women but was invariable for males. The proportion of mucinous carcinoma varied between 13 p. 100 in the cecum and 5 p. 100 in the sigmoid and rectum. The study of incidence with respect to age and location showed that there were less elderly women with left colonic and rectal carcinoma. Epidemiologically, there seems to be two different types of colonic carcinoma: proximal and distal colonic carcinoma (including the rectum), the separation being determined by the splenic flexure.

Charts of 570 patients with colorectal carcinoma surgically treated in one institution during a 13 year period were retrospectively reviewed to evaluate clinicopathologic patterns and surgical results of those 39 years of age or under. Of the 570 patients, 57 (10 percent) were 39 years of age or under, and this group included more female patients than the older control group. Mucinous carcinoma was frequently found on histologic examination, with significantly high incidences of lymph node involvement, peritoneal dissemination, and advanced tumor stages by Dukes' classification in the young patients. The overall cumulative 5 year survival rate in the younger group was significantly lower than that in the control group (41 percent and 55.9 percent, respectively), whereas the difference in rates among the two groups for curative resection was not statistically significant (71.6 percent and 76.3 percent, respectively). Early diagnosis and attempts at curative resection are of utmost importance in the treatment of young patients with colorectal carcinoma.

To determine the clinicopathologic significance of colloid carcinoma in carcinoma of the colon and rectosigmoid/rectum, a retrospective review of 462 patients who underwent potentially curative surgery at the New England Deaconess Hospital was performed. Seventy-seven patients (17%) were identified who had tumors with some component of colloid present. Colloid carcinoma occurred in 49 (11%). The remaining 28 (6%) had adenocarcinoma with colloid features. Compared to patients with pure adenocarcinoma, the 5-year actuarial survival of patients with colloid carcinoma was lower in the colon, rectosigmoid/rectum, and colorectum. Patterns of failure, expressed as the actuarial incidence of failure at 5 years, were examined by histologic condition and stage. Patients with Dukes' Stage B colloid carcinoma had a higher incidence of total failure, and patients with Dukes' Stage C colloid carcinoma had a higher incidence of local, abdominal, and total failure. None of the differences reached statistical significance. The presence of colloid carcinoma may have a real but small impact on the patterns of failure and survival in colorectal cancer.

Peritoneal implants of mucin and columnar epithelium with variable amounts of free peritoneal mucin complicated 11 mucinous ovarian neoplasms. Slides of the primary ovarian tumors were reviewed in eight cases. Although all contained areas of mucinous cystadenomatous tumor of low malignant potential, the neoplasms displayed additional features not well recognized as manifestations of invasive disease in the ovary. Irregular pools of mucin were present in the ovarian stroma and contained at least rare fragments of columnar epithelium in most cases. The epithelium was often more plentiful in the peritoneal mucin. Cytologic atypia was minimal in all except one case. Goblet cells were present in both the ovarian tumor epithelium and the peritoneal implants in most cases and may have a role in dissemination of the tumor. We propose the term "ovarian carcinoma with extracellular mucin production" for this form of mucinous carcinoma; this term is both descriptive of its histologic appearance and indicative of its malignant behavior. Eight of the 11 patients died of their disease from 8 months to 13.5 years after diagnosis. One additional patient died of chemotherapy-related leukemia. The mean survival was 4.2 years. The short-term prognosis is better than that for mucinous carcinoma in general, but most patients eventually die of their disease.

A case in which an infiltrating mucinous carcinoma developed within a suprasphincteric fistula-in-ano is presented. The diagnosis was suspected on biopsy and confirmed by repeat biopsy. The clinical and histological features of this case establish with certainty that the carcinoma arose within the fistula and was not a secondary manifestation of the tumour. It is suggested that this rare complication of chronic fistula-in-ano may be prevented by prompt expert management of complex primary fistula.

Ovarian tumors of low malignant potential (LMP) must be distinguished from benign, "proliferating" ovarian tumors and from frank ovarian carcinoma. Serous and mucinous tumors of LMP demonstrate epithelial stratification, the formation of epithelial tufts, cytologic atypia, and mitotic activity, but they do not demonstrate stromal invasion by epithelial cells, which is a feature of frank carcinoma. Mucinous carcinoma may also be recognized by epithelial stratification exceeding three cell layers and the formation of true cribriform glandular patterns. Although controversial, we do not at present recognize a LMP tumor of endometrioid type but prefer to classify those endometrioid neoplasms with a prominent fibrous stroma and glandular complexity similar to adenomatous endometrial hyperplasia as proliferating endometrioid adenofibromatous and cystadenofibromatous tumors. There is only mild cytologic atypia in such tumors. Because of the moderate to marked cytologic atypia that occurs in some clear cell neoplasms with a prominent fibrous stroma, we believe those tumors do merit a designation of LMP tumors. In both the proliferating endometrioid and LMP clear cell adenofibromatous and cystadenofibromatous tumors, carcinoma must be excluded by an absence of stromal invasion, which is frequently recognized by a confluent glandular pattern. The histologic features of proliferating Brenner tumors are similar to those of low grade, papillary, noninvasive, urothelial carcinoma, whereas we propose that Brenner tumors of LMP show high grade cytologic atypia but remain noninvasive in the ovary.
