Abstract PDF


Invasive endocervical adenocarcinomas, though microinvasive, have the ability to metastasize to the ovaries by retrograde transtubal spread. Endocervical adenocarcinomas with ovarian metastases simulating primary ovarian surface epithelial neoplasms have been reported infrequently. Here, we present a case of adenocarcinoma involving the endocervix and a fallopian tube. The tubectomy might be a possible explanation for the absence of ovarian or peritoneal spread of the tumour.

Case Report

Figure 1: The Endocervix Shows a Focus of Adenocarcinoma.

A 57-year-old female underwent transabdominal hysterectomy with bilateral salpingoophorectomy for adenocarcinoma of the cervix diagnosed by cervical biopsy. On gross examination, the cervix appeared irregular and ulcerated. The endometrium was thinned out and myometrium measured 20mm in maximum thickness. The fallopian tubes showed features of tubectomy. In addition, the right tube was distended measuring 50x15mm. Cut section showed solid and grey white tumour occupying the lumen. Left fallopian tube and both ovaries were within normal limits. Microscopically, the cervix showed extensive ulceration. Only a tiny focus of remnant of adenocarcinoma was seen, possibly from the earlier surgical intervention. The lesion showed papillary pattern formed of multilayered cuboidal to columnar cells exhibiting pleomorphism, scanty cytoplasm and increased mitosis (Figure 1). The uterine wall showed atrophic endometrium with extensive areas of ulceration. No tumor was present (Figure 2). The right fallopian tube showed dilated lumen filled with adenocarcinoma exhibiting complex papillary and solid pattern. Individual tumor cells were cuboidal to low columnar with scant cytoplasm and increased mitosis. The tumor was confined to the mucosa. The mucosa adjacent to the tumor showed no carcinoma in situ changes (Figures 3-6). The left fallopian tube and ovaries were within normal limits (Figures 7 & 8).

According to SEER registry, there are 7.7 new cases of cervical cancer per 100,000 women per year. Improved Pap smear screening has resulted in steady decrease in the number of new cases of cervical cancer over the past decade. But this decrease is limited to squamous cell carcinoma of the cervix only. The incidence of adenocarcinoma of the cervix seems to be rising, especially in women of younger age group [1-3]. Factors like obesity, nulliparity, trends in oral contraceptive usage and difficulty in diagnosing glandular lesions by Pap smear are suggested as reasons [1]. Very few cases of cervical carcinoma involving the upper genital tract have been reported in the literature [4,5]. Increased sampling of fallopian tubes due to change in thoughts about genesis of ovarian tumors has contributed to the increase in number of fallopian tube cancers reported. Rabban et al. [6] studied metastatic fallopian cancers from 100 non gynecological cancers.

Most are adenocarcinomas from breast and colon favoring fimbriae of the fallopian tube and grow as flat to exophytic lesions. They often tend to resemble primary fallopian tube cancers leading to diagnostic difficulty and sometimes require ancillary HPV testing to confirm diagnosis [6,7]. Fallopian tube metastasis from cervical carcinoma is extremely rare and the reported cases are mainly of squamous cell carcinoma [8]. Reyes et al. [9] studied 20 cases of uterine corpus and adnexa involvement by cervical carcinoma. Eight out of ten endocervical adenocarcinomas showed fallopian metastasis [9]. The lesions resembled primary fallopian tube carcinoma. Distinct morphologic analysis and immunohistochemical features are suggested to distinguish metastatic adenocarcinoma from primary tubal malignancies [9]. Over expression of p53 is seen in tubal serous adenocarcinomas while negative p53 indicate endocervical adenocarcinoma.

Tubal serous neoplasm is also positive for WT-1 [10]. The current paradigm of fallopian tube being the origin of serous carcinomas of the ovary has led to increase of fallopian tube sampling, which may have led to increased recognition of metastatic fallopian tube cancers. Thus, all metastatic fallopian tube carcinomas arising from both gynecological and non-gynecological malignancies have recently gained attention [6,11,12]. In our case, morphologic pattern suggest the spread of primary cervical adenocarcinoma to the fallopian tube. Contiguous and transtubal spread is the proposed mechanism of spread of cervical carcinoma to the upper genital tract [10]. Fallopian tube being involved, prognosis and treatment remain unclear with a major concern for tumor spillage into the peritoneal cavity. FIGO staging does not clearly indicate the clinical staging of endocervical carcinoma involving the fallopian tube [13]. The hypothesis of tubal ligation impeding transtubal spread of cancer cells from lower female genital tract has been tested. Lower stage and less mortality was seen in aggressive endometrial carcinoma patients with tubal ligation suggesting the importance of transtubal spread [14]. In conclusion, involvement of upper genital tract by cervical adenocarcinoma is rare. This case is one example, also indicating the impact of tubal ligation on tumor spread.
