Received May 23, 1979 Twenty-three cases of malignant mixed Mullerian tumor of the fallopian tube have been reported; we report another such case. Type of therapy and outcome of these 24 cases is reviewed and the histogenesis is presented. Thirteen patients were treated with surgery alone, with a mean survival of 14.7 months; the longest survival was 43 years. Nine patients were treated with surgery followed by radiation therapy, five patients died within 15 months, and the longest survivor was 44 years. Three patients survived 12, 24, and 17 months. Our patient responded well to combination chemotherapy after surgery and survived 26 months. The small number of patients precludes conclusions on optimal therapy. Survival does not improve with postoperative radiation therapy. The potential benefit of combination chemotherapy following surgery awaits further evaluation.
Primary fallopian tube malignancy is a rare occurrence, and as such, no single institution is able to study a large series of patients. Accordingly, the importance of reporting every case has been emphasized [l-4]. These malignancies account for only O.l-0.5% of all gynecologic cancers [1,2]. Although approximately 950 cases of primary carcinoma of the fallopian tube have been described in literature [l-5], only 23 cases of malignant mixed Mullerian tumors have been reported. Malignant mixed Mullerian tumors are, as a group, uncommon. The most frequent site is the endometrium, followed in decreasing incidence by the vagina, the cervix, and the ovary. The fallopian tube is the least common site, accounting for less than 4% of the reported cases [6,7]. The purpose of this paper is to report the 24th case of this unusual Mullerian tumor, and briefly review the literature concerning the outcome of 23 previously reported cases. HISTOGENESIS
By definition, malignant mixed Mullerian tumors contain both malignant epithelial and stromal elements. The stromal component may contain tissues homolo381 OWO-8258/80/030381-13$01.00/O Copyright @ 1980 by Academic Press, Inc. All rights of reproduction in any form reserved.

gous and/or heterologous to the Mullerian duct system. Homologous types, such as smooth muscle, endometrial stromal cells, etc., are normally derived from Mullerian tissue. Heterologous elements such as fat, striated muscle, bone, and cartilage are foreign to the Mullerian duct system. It is believed that the origin of both the epithelial and the stromal components is the multipotent mesoderm of the Mullerian system [S]. Malignant mixed Mullerian tumors have been referred to differently in literature. McFarland noted 110 synonyms for this tumor [93. A classification of female genital tract malignancies with sarcomatous components alone or with an epitheha1 component has been formulated only for tumors of endometrial origin [lo]. Norris et al. divided this group of tumors arising from endometrium as carcinosarcoma with homologous sarcomotous elements and malignant mixed mesodermal tumor composed of sarcomatous components foreign to the tissue of origin. They related the better prognosis for the former [I 1,121. To understand this seemingly diverse group of neoplasms, it is important to review the embryology of the female genital tract. In the lo-mm embryo a fold of tissue along each urogenital ridge rolls inward to form the Mullerian duct by invagination of the coelomic epithelium into the vaginal mesenchyme [9]. In the female the caudal portion of the Mullerian duct becomes fused forming the upper vagina and uterus. The cephalad portion of the Mullerian duct remains separated, forming the individual fallopian tubes [7]. In view of a common embryologic origin of these organs, the histologic spectrum of malignant mixed Mullerian tumors becomes understandable. On the basis of multipotentiality of Mullerian stroma (which apparently retains a latent capacity to differentiate into a variety of cell types by a yet unknown stimulus) it is not unreasonable to find this tumor in the vagina, uterus, fallopian tube, or ovaries [7]. Although any benign or malignant tumor including malignant mixed Mullerian tumor noted elsewhere in the paramesonephric system may occur in the tube, the lack of physiological activity of tubal Mullerian stroma has been suggested as the basis for these tumors occurring less commonly in this site than in the endometrium
[6,7,131. BRIEF REVIEW
OF PREVIOUSLY
REPORTED
CASES
In 1973, Wu et al. [7] summarized 14 cases including one of their own. Acosta, Kaplan, and Kaufman reported three additional cases in 1973 [8]. Manes et al. [ 141 reported four cases in 1976 but two patients from their series had questionable diagnosis (Cases 20 and 22 from Table 1). In these patients hysterectomy was not performed, and it could not be determined whether the tumor was primary in the uterus, which is the most common site for this malignancy. One case was reported by Jain in 1977 [ 151. Henderson et al. reported one additional case in 1977 [5]. The present study is the 24th such recorded case. Table 1 summarizes the 24 recorded cases including the present case. CASE HISTORY
M.K., a 62-year-old white woman was admitted to the gynecologic oncology service on May 11, 1975, following a left inguinal node biopsy which revealed poorly differentiated adenocarcinoma. The patient had noticed a left groin mass 5

months prior to biopsy. She was otherwise asymptomatic. She had her last menstrual period 6 years prior to admission with normal menstrual history and no postmenopausal bleeding. The patient’s past history was noncontributary. She was Gravida I, Para I. Examination showed a biopsy site in left inquinal area with a 2 x 2 cm node. No ascites or abdominal distention were noted and no other nodes were palpable. Pelvic examination revealed an 8 x 10 x IO-cm semisolid mass in the region of the left ovary. The hemoglobin was 9 g, red blood count: 4.89 mm3, white blood count: 8,700 mm3, total protein: 7.3 g/dl, albumin: 3.7 g/d], globulin: 3.6 g/dl, alkaline phosphatase 11 IU/liter, serum glutamic oxaloacetic transaminase: 16/IU/liter, chest film, intravenous pyelogram, barium enema, and upper gastrointestinal were normal and pap smear was negative. After transfusion of 2 units of packed cells, an exploratory laparotomy was performed on May 21, 1975, and the following findings were noted: (a) The left adnexal region had a large fungating mass measuring 10 x 8 x 8 cm, taking origin from the fallopian tube. The left ovary was of normal size. No ascites was present. (b) Uterus, right fallopian tube, and ovary appeared normal. (c) The paraaortic area was studded with enlarged firm metastatic lymph nodes. (d) Two large implants of tumor on the omentum and a large 5 x 4 x 5-cm mesenteric node were detected. A total abdominal hysterectomy and bilateral salpingo-oophorectomy, omentectomy, and resection ot mesenteric node were performed. Microscopic examination revealed that throughout the specimen both carcinomatous and malignant stromal components were present in varying proportions. The adenocarcinomatous element was well differentiated with papillary and glandular patterns admixed (Fig 1). Cystic areas of varying sizes, lined by carcinomatous cells evidencing papillary projections were common. Other areas showed a more compact proliferation of neoplastic glands. The malignant stromal component intermingled with the carcinomatous glands. Its appearance throughout the tumor was similar. The stromal cells were undifferentiated and were found in loose bundles which were frequently associated with thin-walled vessels and varying amounts of stromal edema (Fig. 2). The cells were spindle shaped with varying amounts of cytoplasm. The nuclei were hyperchromatic and evidenced significant variation in size. No evidence of rhabdomyoblast or cartilagenous differentiation was observed. The above features were interpreted as that of a malignant mixed Mullerian tumor, homologous type. The patient had an uneventful postoperative course. She was treated with chemotherapy consisting of vincristine, actinomycin D, and cyclophosphamide. Cyclophosphamide, 10 mg/kg/day, and actinomycin, 0.5 mg/day, were administered for 5 days and repeated every 4 to 5 weeks. Vincristine was given in a dose of 2.5 mg weekly. Only eight courses of vincristine were given because the patient developed peripheral neuropathy from which she recovered when vincristine was discontinued. The patient did very well and her response to chemotherapy was excellent. The left inguinal nodes completely disappeared and she was active with no clinical sign of disease. She did well for 20 months until February 1977 when tumor progression was noted. For 4 months prior to this date she had not

patient reported by Acosta et al. [8] (Case 16 from Table 1) is also questionable since the tube and ovary were both involved with tumor and no definite diagnosis of primary tubal tumor could be made. There is clinical similarity in all of the reported cases with adenocarcinoma of the uterine tube. The age incidence is between 14 and 76 with a mean age of 55 at the time of diagnosis. This is similar to age incidence of adenocarcinoma of fallopian tube and malignant mixed Mullerian tumor of other sites [ 1,2,4,5,17]. In the early stage, the tumor does not produce any clinical symptoms even when it attains large size. The late manifestations are nonspecific such as vaginal spotting, cramping, abdominal pain, and abdominal enlargement. Seldom is a preoperative diagnosis made. In the majority of cases the diagnosis is achieved by microscopic examination. The tumor usually develops intraluminally as a polypoid mass and may produce unilateral or bilateral hydrosalphinx. The routes of metastasis are similar to that of carcinoma of the fallopian tube. It may spread via intraperitoneal surface dissemination, lymphatic dissemination, or blood-borne metastasis. The neighboring structures such as ovaries, contralateral fallopian tube, lymph nodes, bowel, and peritoneal surfaces are the most common metastatic sites. Distant metastasis are rare and may include liver, lung, and bones. Metastatic lesions may contain stromal or epithelial elements, or both. The longest reported survival to date has been 54 months. The 23 patients recorded survived between 1 and 54 months after operation with a mean survival of 17.1 months. The cause of all deaths was metastasis. The present case lived 26 months after operation and responded well to chemotherapy consisting of vincristine, actinomycin D, and cyclophosphamide. The mean age of patients with mixed Mullerian tumor of the endometrium is 5 1 and mean survival was reported to be 8.4 months [ 171. This is similar to the incidence of mixed Mullerian tumors of the fallopian tube. The mean survival for mixed Mullerian tumors of the tube was slightly higher but is not significant due to the small number of reported cases. Therefore, in both the tube and endometrium this tumor occurs at the same mean age and it seems that they have the same biologic behavior and fatal outcome. All patients had partial or complete removal of the tumor including total abdominal hysterectomy and bilateral salpingo-oophorectomy. Radiation was used as a therapeutic agent in nine patients [5-8,13,14,18,19]. One patient lived for 44 years after therapy, and five died within 15 months [6,8,14,18,19]. Three patients survived for 12, 24, and 27 months, respectively, after their cases were reported [5,7,141.
Thirteen patients were treated with surgery alone (see Table 1). Seven of these patients were lost to follow-up [20-261. The remaining six patients had a mean survival rate of 14.7 months [8,13-15,271. One of these patients lived 4+ years without evidence of recurrent disease [ 141. Our patient received a total abdominal hysterectomy and bilateral salpingo-oophorectomy, omentectomy, and removal of all resectable gross tumor followed by chemotherapy. Her response was good and she survived for 26 months. Due to the small number of reported cases with this neoplasm, no definite conclusions regarding the best method of therapy can be reached. Because the

prognosis is generally poor, an aggressive mode of therapy is recommended even though some of the patients reported showed a relatively slow course of disease with late recurrences. The primary therapy is surgery. Malignant mixed Mullerian tumors of the endometrium [28], cervix [29], and ovary have been relatively radioresistant. Also, this seems to be a fact in the management of this tumor arising in the fallopian tube as it has little effect on the natural course of this disease when compared to the mean survival between surgery followed by radiation therapy versus surgery alone. Surgery followed by chemotherapy may have a potential benefit. REFERENCES 1. Gusberg, S. B., and Frick, H. C. (Eds.) Corscaden’s gynecologic cancer, Baltimore, Williams & Wilkins, p. 510, (1970). 2.
