Squamous cell carcinoma of the vulva in Brazil: prognostic importance of host and viral variables.

BACKGROUND: Certain clinicopathologic features of vulvar squamous cell carcinoma have been correlated with adverse prognosis. However, few large-scale studies have addressed their role in patient survival. This study examined the relationship between multiple variables and prognosis in a large group of vulvar cancers in Brazil. METHODS: One hundred eighty-four Brazilian women with vulvar carcinoma were studied and the following variables recorded: age, pathologic TNM stage, survival, histologic grade, tumor histologic pattern, invasion pattern, tumor thickness, and tissue stromal and inflammatory response. Human papillomavirus (HPV) was detected by polymerase chain reaction amplification of extracted archival DNA. Data were analyzed using Cox proportional hazards modeling. RESULTS: After controlling for age, the probability of cancer survival decreased with increasing age, stage, grade, and tumor thickness, a fibromyxoid stromal response, infiltrative growth pattern, and basaloid histologic pattern. With the exception of fibromyxoid stromal response, each of these variables remained prognostically significant after adjustment for several other predictors in a multivariate model. Women whose tumors displayed a basaloid pattern were 3.5 times as likely to die from cancer than those with keratinizing tumors [hazard ratio (HR) = 3.5, 95% CI(1.3-9.2)]. An infiltrative invasion pattern strongly increased the probability of cancer death [HR = 4.6, 95% CI(1.9,11.4)]. HPV status did not influence survival, despite its association with basaloid histology. CONCLUSIONS: Previously reported associations of negative HPV status and fibromyxoid response with adverse prognosis in vulvar cancer were not confirmed by multivariate analysis. Basaloid variants, and particularly diffusely infiltrative tumors, carry an adverse prognosis.     

Squamous cell cancer of the cervix: prognostic factors related to survival

Seven hundred and fifty-three patients with invasive squamous cell cancer of the cervix treated at the University of Michigan from 1970–1985 are reported. These included stage IA 43, stage IB 345, stage IIA 27, stage IIB 163, stage IIIA 4, stage IIIB 113, stage IVA 32, stage IVB 26. The age ranged from 18 to 92 years with a mean of 49.9 years. Clinical characteristics included: nulliparity 11%, married 93%, obese 41%, hypertensive 37%, diabetes 10%, smoking 50%, bleeding 76%. The cumulative five-year survival for all patients was 67% and this was influenced by the stage of disease: stage IA 98%, stage IB 89%, stage IIA 72%, stage IIB 62%, stage III 37%, stage IVA 14%, stage IVB 4%. Patients with a well-differentiated tumor had an 85% survival rate while those with a poorly differentiated tumor had a 57% survival rate. The probability of metastatic disease to lymph nodes corresponded to the stage of disease; stage I 17%, stage II 55%, stage III 70%, stage IV 81%. When lymph nodes were negative, the survival rate for all patients was 86% while those with positive nodes had a 33% survival rate. Factors which influenced survival in the univariate analysis included stage, node status, tumor grade, age, interval from previous pelvic examination, diabetes. Only stage, node status and tumor grade maintained significance in the multiple proportion hazard analysis.     

Clinical and pathological prognostic factors in squamous cell carcinoma of the vulva

OBJECTIVE: The objective of this study was the prognostic analysis of clinicopathologic variables related to primary tumor and to lymph node metastases. METHODS: We retrospectively analyzed 389 cases of squamous cell carcinoma of the vulva. The following variables were studied: patients' age, diameter and location of the tumor, clinical tumor characteristics, depth of invasion, grade, lymphovascular space involvement (LVSI) and lymph node status. In the subset of 110 node positive patients, we evaluated number of positive nodes, laterality, extension of node dissection, lymph node chains involved, presence of extracapsular spread and rate of lymph node replacement. All variables with P value < 0.2 by the univariate analysis were successively subjected to multivariate analysis (Cox proportional hazard model). RESULTS: Among all the tumor-related variables age, clinical tumor characteristics, LVSI and lymph node status were found to be statistically significant predictors of survival for the log-rank test. On the basis of multivariate analysis, the nodal status was the most significant independent prognostic factor (hazard rate [HR]: 2.06; confidence interval [CI] 95%: 1.57-12.07) followed by LVSI (HR: 3.47; CI95%: 1.85-7.85). The independent prognostic factors among the variables relative to positive nodes were the percentage of nodal replacement (HR: 6.99; CI95%: 3.51-16.14) and the extracapsular spread (HR: 4.88; CI95%: 2.96-10.14). CONCLUSIONS: Lymph node status and nodal features, such as extracapsular spread and nodal replacement rate, were shown to be independent factors. These factors should be considered to identify high risk patients and in planning further adjuvant therapy.     

Squamous cell carcinoma of the vulva with cutaneous metastases

Cutaneous metastases from squamous cell carcinoma of the vulva are extremely uncommon. A 72-year old woman had undergone vulvectomy with bilateral inguinal lymphadenectomy. The operative specimen showed tumor infiltration in the resection borders to a considerable depth. Thereafter she received radiotherapy. Seven months after the primary operation, multiple non-tender tumor metastases appeared on the lower abdomen. These metastases result from cross-section and obstruction of lymphatic channels.     

Squamous cell carcinoma of the vulva and Fanconi anemia

Malignant neoplasia frequently occurs with Fanconi anemia. Generally this represents hematologic disease; however, solid tumors may also appear. The woman described here developed squamous cell carcinoma of the vulva at age 28, and is the third such case in a patient with Fanconi anemia that has been reported. It is a diagnosis to be considered for the young patient with this type of carcinoma. Increased chromosomal breakage in this syndrome may be important in the pathogenesis of these neoplastic changes.

Prognostic factors in invasive squamous cell carcinoma of the vulva.

Histological malignancy grading and its correlation to prognosis were retrospectively investigated in 303 cases of squamous cell carcinoma of the vulva. A scoring system based on several variables is suggested. The scores and the individual histological variables were tested along with clinical factors with a view to predicting survival. Various histological variables including mode of invasion, depth of invasion and nuclear polymorphism, as well as the sum of the scores were good predictors of survival. The study revealed a significantly better survival rate in stage III if no metastases were suspected. An age factor was also found showing that cancer of the vulva has a worse prognosis in older women.     

Value of prognostic parameters in squamous cell carcinoma of the vulva

In a series of 137 patients with cancer of the vulva who had undergone radical surgery we investigated, by means of a Cox regression model, which combination of clinical variables and clinical as well as histopathological variables afforded the best prediction of survival/death from cancer and survival/death from other causes. Among clinical variables the best prediction was afforded by a combination of tumor site in the clitoris/not clitoris, tumor size greater or smaller than 40 mm, obesity/not obesity, and age. Among clinical and histopathological variables the best prediction was by a combination of groin node metastases/not groin node metastases, tumor site in the clitoris/not clitoris, degree of differentiation high/moderate + low, and age. The combination of clinical and histopathological variables had a significantly better predictive power than clinical variables alone. The best prognostic group in both combinations had a 5-year-survival for cancer of 98%, while the poorest prognostic group in the two combinations showed a 5-year survival for cancer of 19 and 9%. The best predictors of death from causes other than cancer were age and a poor general health. It is concluded that the poorest prognostic group is definitely under treated and that the best prognostic group is presumably over treated. Patients in poor general health and with a good cancer prognosis should receive a more conservative treatment.     

The influence of some prognostic factors on the clinical outcome of patients with squamous cell carcinoma of the vulva.

The present paper examined the influence of patient age, surgical T stage, tumor size, tumor differentiation and lymphnodal status on the clinical outcome of 29 patients with primary vulvar squamous cell carcinoma treated with radical surgery. Eighteen patients underwent radical vulvectomy with bilateral inguinal-femoral lymphadenectomy alone; 10 patients had additional bilateral pelvic lymphadenectomy; another patient had additional bilateral pelvic lymphadenectomy and anterior pelvic exenteration for a carcinoma of the clitoris involving the urethra. Nine patients developed relapsing disease; the site of recurrence was local in 4 patients, inguinal in 2, both local and inguinal in one patient, pelvic in one, both pelvic and distant in one. Eight recurrences occurred within 24 months from surgery; another patient developed an inguinal recurrence 45 months after operation. The actuarial 5-year disease-free survival rates were as follows: 64% for patients younger than 70 years and 63% for patients 70 years of age or older (p = not significant); 79% for patients with surgical T1-T2 stage disease and 30% for those with surgical T3 stage disease (p = 0.01); 88% for patients with tumor size less than 3 cm and 31% for those with tumor size greater than 3 cm (p less than 0.001); 66% for patients with well or moderately differentiated tumor and 51% for those with poorly differentiated tumor (p = not significant); 82% for patients with negative groin lymph nodes and 39% for those with positive groin lymph nodes (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)     

Inflammatory cell infiltration and survival in squamous cell carcinoma of the vulva

Summary. The prognostic significance of tumour infiltration by inflammatory cells in squamous cell carcinoma of the vulva was examined in a cohort of 34 patients surviving without recurrence for at least 5 years after radical surgery, and a comparative cohort of 35 patients who died of their diseases. Overall, heavy inflammatory infiltration correlated with a good prognosis and light infiltration with a poor one, independent of other indices such as differentiation, tumour size and nodal status. IgA-containing cell infiltration also correlated with a good prognosis but the presence of IgA-containing cells did not alone account for all the inflammation in the good prognosis group. An immunological response to the tumour may be influencing prognosis. At a practical level, the extent of inflammation appears, at least in this material, to be as useful a prognostic index as many more conventional ones.

Basal cell carcinoma of the vulva.

A clinical and histopathologic study of material from a series of 17 patients with basal cell carcinoma of the vulva are reviewed. The tumors occurred primarily in elderly patients (average age, 59 years), the majority of whom were Causasian. Presenting symptomatology consisted primarily of pruritis vulvae and/or the presence of a vulvar mass (79%) of long duration (average, 6 years, 7 months). The lesions were described grossly as ulcerations or masses located on the anterior labium majus. Etiologies were indeterminate although 2 patients had previously received vulvar irradiation. Therapy consisted primarily of wide local excision and was effective in that follow-up studies in 16 patients revealed no deaths attributable to basal cell carcinoma. These data indicate that basal cell carcinoma is a locally invasive nonmetastasizing tumor best treated by wide local excision providing the tumor edge does not extend to the margin of excision.     

Squamous carcinoma of the vulva: results of treatment, 1938 to 1976.

Clinical data on 264 patients with squamous cell carcinoma of the vulva seen between 1938 and 1976 are reported. Two hundred and four patients were "eligible" for 5 year assessment for a 55% survival rate. Patients treated with radical vulvectomy and bilateral lymphadenectomy had a corrected 5 year survival rate of 86% if the lymph nodes failed to show metastatic disease. Twenty-eight percent of the patients treated with lymphadenectomy had lymph node metastasis at the time of surgery. The presence of lymphatic metastasis appeared to be the most significant prognostic factor. The results obtained have led to a degree of individualization in current treatment policies, together with a re-evaluation of the possible role of radiotherapy.     

Large cell neuroendocrine carcinoma of the cervix: prognostic factors and survival advantage with platinum chemotherapy

Objective

Large cell neuroendocrine carcinoma of the cervix (LCNEC) is a rare cervical neoplasm associated with poor survival. Our objective was to identify treatments associated with improved survival.

Methods

Relevant data were abstracted from an English literature MEDLINE search, SEER database, and a patient treated at our institution. Multivariate analysis was performed by generating Cox proportional hazard ratios.

Results

We identified 62 patients with LCNEC: 49 cases from the English literature, 12 patients in the SEER database and our patient. Out of the 62 women, median age was 37 (range, 21-75). FIGO stage was as follows: 58% had stage I disease, 16% had stage II, 2% had stage III, 8% had stage IV disease and 16% had no stage documented. Of all patients, 73% underwent primary surgery, 4.7% underwent primary radiation, 4.7% underwent chemotherapy, 8% had chemoradiation, and 9.6% had no primary treatment. Of all patients, 58% died of disease, 26% had no evidence of disease, 3% were alive with disease, and 13% had no survival data. The overall median survival was 16.5 months (0.5-151 months). Median overall survival for stage I, II, III, and IV cancers was 19, 17, 3, and 1.5 months, respectively. In a multivariate analysis, earlier stage (p < 0.00001) and the addition of chemotherapy (p = 0.04) were associated with improved survival. Both platinum agents (p = 0.034) and platinum and etoposide together (p = 0.027) were associated with improved survival.

Conclusions

Perioperative chemotherapy, in particular platinum with or without etoposide, improves survival in the rare LCNEC.     

Squamous cell carcinoma of the vulva: study of ploidy, HPV, p53, and pRb.

Seventy-one cases of invasive squamous cell carcinoma (ISCC) of the vulva were compared with 18 cases of vulvar intraepithelial neoplasia (VIN) and 21 cases of lichen sclerosus. Ploidy was studied by image analysis, HPV-DNA by PCR, and p53 and pRb by immunohistochemistry. Univariate and multivariate statistical analyses were performed. The mean age of the patients with ISCC was 70.6 years; only 8.5% were < 60 (range, 43-89) years. For the 43 patients with follow-up, FIGO surgical stages were I in 16.2%, II in 48.8%, III in 27.9%, and IV in 6.9%. The 5-year survival was 90% for the patients with curative surgery (vulvectomy and lymphadenectomy) and 32% for those with tumors in stages III to IV. Previous history of nonneoplastic epithelial alterations was recorded in 54%. Vascular invasion was detected in 4.3% and perineural invasion in 21.4%. Inguinal lymph node metastases were present in 34.9% of the cases. Fifty-one (72%) ISCCs were aneuploid, HPV-DNA-16 was detected in 7 (12.3%) cases, overexpression of p53 was found in 40 (56%), and pRb expression was negative in 15 (21.4%). Fifteen cases (80%) of VIN were aneuploid, 5 (27.7%) contained HPV-DNA, 11 (61%) were positive for p53, and all immunoreacted for pRb. All lichen sclerosus cases were diploid, did not contain HPV-DNA, failed to stain for p53, and were positive for pRb. Our study confirmed the prognostic value of conventional pathological features: stage, lymph node metastasis, histological grade, and vascular and perineural invasion; all were statistically significant for survival in the univariate analysis. Also, ploidy was significant in patients with stages I and II tumors. The only significant variable in the multivariate analysis was stage. p53 overexpression appears as a late event in vulvar carcinogenesis, but it may occur before tumor invasion. Lack of pRb expression can occur in vulvar neoplasia, but it does not seem to play any role in the initiation or prognosis of vulvar ISCC.     

Squamous cell carcinoma antigen and carcinoembryonic antigen levels as prognostic factors for the response of cervical carcinoma to chemotherapy

Between January 1986 and December 1988, 36 patients with primary advanced or recurrent cervical carcinoma were treated with cytostatic drugs in our department. Treatment at first was a combination of cisplatin and etoposide. After August 1987, a combination of carboplatin and ifosfamide was used. In all patients showing primary response to therapy, the squamous cell carcinoma antigen (SCC) and carcinoembryonic antigen (CEA) levels fell rapidly to normal after one or two cycles. In contrast, clinical remission was not obtained in those patients with levels which remained high or rose again following an initial decrease. Chemotherapy is often the only available therapy for advanced cervical carcinoma or recurrent disease, although the results of treatment, especially in squamous cell carcinoma, remain poor. The course of the SCC or CEA levels can help to decide whether the patient would profit from a continuation of the therapy. With the tumor markers, treatment can be individualized so that, above all, cases of therapy failure or further tumor progression can be detected early and the patient can be spared the severe side effects of the treatment.     

Squamous cell carcinoma with sarcomatoid features of the vulva: a case report and review of literature

BACKGROUND: A squamous cell carcinoma with sarcomatoid features of the vulva is an extremely rare malignancy of the female genital tract. This type of tumor is known to grow rapidly and associated with poorer clinical outcomes than those of squamous cell carcinoma of the vulva. CASES: A 43-year-old woman presented to our institute with a 4-month history of an aggravated vulvar mass. A radical local excision, bilateral inguinal lymph node dissection and laparoscopic assisted vaginal hysterectomy were performed. The FIGO stage of the vulvar cancer was stage II (T(2)N(0)M(0)) and the pathologic finding was consistent with a poorly differentiated squamous cell carcinoma with extensive sarcomatoid features. No further treatment was given and there was no clinical evidence of recurrence during the 2 years of follow-up. CONCLUSION: A squamous cell carcinoma with sarcomatoid features of the vulva is a tumor with aggressive biological behavior. To date, there have been only 15 cases of this disease reported in the literature. So, a collection and close study of these cases would be extremely useful in singling out and identifying the best treatment possible for this type of tumor.
