The characteristics and treatment of eight patients with primary adenocarcinoma of the vagina were reviewed. Cytologic smears of the vagina aided in the diagnosis of adenocarcinoma but, less often, detected vaginal adenosis. Good correlation existed between the degree of differentiation of the primary tumor and the tendency toward lymphatic spread. The clinical stage, size of the primary lesion, presence and duration of symptoms and lymphangiographic findings were not helpful in this regard. Pretreatment lymphadenectomy as a basis for operative staging demonstrated the critical importance of the status of the lymph nodes in the planning of therapy and determination of prognosis. Vaginal reconstruction and ovarian preservation facilitated rehabilitation.

Gynecologic cancer records of 4,238 patients treated between 1956 and 1974 were reviewed. Sixteen patients developed noeplasia in the cervix or vagina 10 or more years following pelvic irradiation. Three patients had squamous carcinoma in situ; the other 13 patients had invasive squamous cancer involving the upper vagina. Only 1.26 per cent of invasive carcinoma of the cervix treated by radiation therapy from 1956 to 1966 presented with a late or recurrent or new primary tumor involving the vagina or cervix 10 or more years after primary treatment. The authors conclude that the risk of developing radiation-induced carcinoma in the upper vagina or cervix following pelvic irradiation is low. Follow-up Pap smears are indicated for all patients treated for cervical or vaginal malignancies by radiation therapy in order to detect vaginal neoplasia as well as recurrent carcinoma of the cervix.

A 50-year-old Japanese female with choriocarcinoma showed three unusual features: the primary tumor developed in the vagina ectopically without uterine lesion; the first symptoms of atypical vaginal bleeding and coughing occurred 23 years after the last pregnancy; and the tumor appeared during postmenopause. The possible mechanisms for the ectopic location and latency are discussed.

Human papillomavirus (HPV) type 16 DNA was found in three separate neoplastic lesions within a female patient. The physical state of the viral DNA in each lesion was determined by two-dimensional agarose gel electrophoresis. The primary cervical tumor contained large amounts of several distinct episomal forms as well as integrated HPV DNA. Metastatic tumor tissue found in the vagina had greatly reduced levels of episomal DNA and a viral DNA integration pattern that was different from that of the primary tumor. The vulvar carcinoma in situ had what appears to be free and integrated forms of viral DNA. The results show that although metastatic tissue retained HPV DNA, further rearrangements of the integrated viral DNA pattern found in the primary tumor may occur with a dramatic decrease of episomal forms during malignant progression.

The clinical and pathological features of three personally observed and six previously reported cases of renal cell carcinoma metastatic to the ovary are reviewed. The patients' ages ranged from 39 to 64 (average, 52) years. In five patients the ovarian tumor was discovered first. In four of these patients renal tumors were detected during the initial clinical studies or in the early postoperative period, but in the fifth the renal primary tumor was not detected until 8 years later. The ovarian tumor in two cases was initially misdiagnosed as a primary ovarian clear cell carcinoma. In the remaining four patients the ovarian metastasis was detected 5 months, 12 months, 19 months, and 11 years after a renal tumor had been removed. In two patients the initial clinical manifestations were due to a metastasis of the renal tumor, to the thyroid gland in one and to the vagina in the other. The renal tumors in these nine patients typically were well-differentiated renal cell adenocarcinomas of clear cell type. The ovarian tumors measured from 7 to 18 (average, 12.5) cm in greatest dimension; two of them were bilateral. Grossly they were usually solid or solid and cystic; one was a unilocular cyst with a predominantly smooth lining and a 2.5-cm solid nodule in one area. The solid component of the tumors was typically either uniformly yellow or had focal yellow areas with hemorrhagic foci. Microscopic examination showed a relatively uniform picture in most cases: solid or alveolar nests of epithelial cells with abundant clear cytoplasm or tubules lined by clear cells and containing intraluminal eosinophilic material and extravasated blood.(ABSTRACT TRUNCATED AT 250 WORDS)

A retrospective 7 1/4-yr study was performed to evaluate the diagnostic accuracy of fine-needle aspiration (FNA) cytology in the cell typing of persistent or recurrent gynecologic malignancies. A total of 202 aspirates were obtained from 163 patients with documented malignancies of the cervix, uterus, ovary, vulva, and vagina. Information concerning the primary tumor was obtained from surgical reports and/or medical records. In 168/202 cases (83%), the histological diagnosis, including primary tumor cell type and subtype (ex. squamous cell carcinoma, large cell keratinizing), were available. In 12/202 cases (6%), only the tumor cell type (ex. squamous cell carcinoma) was known, and in the remaining 22 cases (11%), only the location of the primary neoplasm was attainable. Aspirated sites included pelvic wall and organs (77 cases), lymph nodes (51 cases), thoracic organs (18 cases), and abdominal wall and organs (56 cases), including liver (33 cases). Of the 168 cases with known histologic diagnoses, the FNA results were positive in 109 (65%). The positive results were divided into three groups: group I, the cytologic findings were predictive of the histologic diagnoses (84 cases, 77%); group II, tumor cell subtyping was not possible on cytology (17 cases, 16%); group III, neither tumor cell typing nor subtyping was possible on cytology (8 cases, 7%). Of the 34 cases in which only the histologic tumor cell type or primary tumor location was known, 13 (38%) were positive on FNA.(ABSTRACT TRUNCATED AT 250 WORDS)

This study was undertaken to review the long-term results of multivisceral resection of locally advanced colorectal carcinoma. Between 1964 and 1980, 1042 patients underwent exploratory surgery for colorectal cancer. Of these, 58 patients (5.5%) underwent curative multivisceral resection for suspected contiguous invasion by the primary tumor. Follow-up was complete for all patients. The primary tumors were located in the rectum (38 patients), sigmoid (9 patients), left colon (6 patients), and right colon (5 patients). En bloc resection of other viscera included uterus, adnexa, bladder, vagina, small intestine, abdominal wall, liver, stomach, kidney, and ureter. The operative morbidity and mortality rates were 31% and 1.7%, respectively. Resection margins were free of tumor in 54 patients. In the four patients with tumor-positive resection margins, recurrence of disease was evident between 8 and 22 weeks after surgery (mean survival time, 8.2 months). Carcinomatous invasion of the resected contiguous organ was confirmed in 49 patients (84%). The mean survival time for patients without lymph node metastases was 100.7 months, but it was only 16.2 months (p less than 0.01) for patients with lymph node metastases. Actuarial 5-year disease-free survival rate for patients without lymph node metastases was 76% (36 of 47 patients). None of the patients (0 of 11) with lymph node metastases survived for 5 years. Three of 36 of the 5-year survivors experienced recurrence of disease before the seventh postoperative year; no cancer-related deaths occurred between 7 and 25 years. These data suggest that survival in locally advanced colorectal carcinoma is more dependent on lymph node status than on the extent of local invasion. Effective disease control associated with survival in the long term can be achieved by multivisceral resection.

Palpable inguinal lymph nodes are a common finding in gynecologic patients. Assessment of such nodes is especially important in the clinical staging of pelvic cancers. To determine the accuracy, safety, and usefulness of fine-needle aspiration in this setting, we retrospectively reviewed pathologic and clinical data from 62 consecutive aspirates of inguinal lymph nodes in 48 gynecologic patients, of whom 42 had cancer. Aspirates from 37 patients yielded diagnostic material. Aspirated tumor cells consistently reflected the primary tumor histology. Tumors included carcinomas of the vulva, vagina, and cervix, and carcinomas and mixed mesodermal cancers of the corpus and ovary. Node excision and clinical observations provided adequate follow-up for 19 positive and 15 negative aspirates, and identified no false positives and two false negatives. The role of fine-needle aspiration varied with the tumor type and stage. It provided the first microscopic diagnosis of cancer in six patients and the first diagnosis of metastasis in six others. Decisions concerning surgery, radiation ports, and chemotherapy frequently depended on the results of fine-needle aspiration. There were no complications from the procedure. Fine-needle aspiration is an accurate, safe, and useful method for assessing clinically suspicious inguinal nodes.

The accuracy of magnetic resonance (MR) imaging in staging invasive carcinoma of the cervix was determined retrospectively in 57 consecutive patients in whom the extent of disease was surgically confirmed. MR images were analyzed for (a) location and size of the primary tumor; (b) tumor extension to the uterine corpus, vagina, parametria, pelvic sidewall, bladder, or rectum; and (c) pelvic lymphadenopathy. The accuracy of MR imaging in determination of tumor location was 91% and for determination of tumor size within 0.5 cm, 70%. Its accuracy was 93% for vaginal extension and 88% for parametrial extension. Pelvic sidewall, bladder, and rectal involvement were accurately excluded in all patients, but the positive predictive values were 75%, 67%, and 100%, respectively. Overall, the accuracy of MR imaging in staging was 81%. MR imaging is valuable because it can accurately demonstrate tumor location, tumor size, degree of stromal penetration, and lower uterine segment involvement. It is also valuable for ruling out parametrial, pelvic sidewall, bladder, and rectal involvement.

Adjuvant combination chemotherapy with cyclophosphamide, doxorubicin and cisplatin was administered to 36 patients after cystectomy for bladder cancer. Therapy was tolerated well except for 1 patient who suffered a fatal chemotherapy complication. Indications for adjuvant chemotherapy included vascular invasion of the primary tumor, perivesicular tumor involvement, invasion of adjacent pelvic viscera (vagina and prostate) and nodal metastases. There were 53 concurrently treated patients who did not receive adjuvant chemotherapy despite similar unfavorable pathological indications (high risk control group). Survival rates (61 and 73 per cent, respectively) were not significantly different for those patients treated with adjuvant chemotherapy and an additional group of 158 patients who underwent cystectomy during the study period but who had no adverse pathological findings (low risk control group). Survival rates differed significantly between the low risk (73 per cent) and high risk (38 per cent) control groups (p less than 0.001). Patients with unfavorable histological findings who received adjuvant chemotherapy had a significant survival advantage over the high risk control groups (61 versus 38 per cent, p equals 0.03). These data confirm the predictive value of post-cystectomy pathological findings and suggest that adjuvant chemotherapy with cyclophosphamide, doxorubicin and cisplatin not only prolongs the survival free of disease for patients at high risk for recurrence but it also may ultimately increase the cure fraction of such patients.
