An unusual cervical carcinoma showing exception to epitheliotropism of human papillomavirus.

Human papillomaviruses (HPV) infect epithelial tissues but have not been previously detected within mesenchymal cells. During a systematic investigation of FIGO stage Ib cervical cancers with colorimetric in situ hybridization, we detected HPV 16 DNA within the stromal compartment of an unusual undifferentiated carcinoma. The mesenchymal nature of the HPV-containing cells was confirmed by immunohistochemistry and electron microscopy. No viral particles were identified. Sequencing the majority of the HPV 16 genome identified few changes from the revised reference clone; all previously reported in other HPV 16 variants. These viral changes are unlikely to explain the exceptional mesenchymal localization of the HPV 16 DNA in this case.

Ureteral rhabdomyosarcoma.

Rhabdomyosarcoma is a malignant tumor well known to urologists. These tumors arise from the genitourinary system in 20% to 25% of cases, most commonly from the bladder, prostate, vagina, and paratesticular region. This is the first reported case of a rhabdomyosarcoma arising from the ureter. The radiographic findings and ureteroscopic appearance of this tumor suggested a benign fibroepithelial polyp; however, a ureteroscopic biopsy and subsequent nephroureterectomy revealed an embryonal rhabdomyosarcoma.

Clinical determinants of survival from stage Ib cervical cancer in an inner-city hospital.

This study reviewed a high-risk population of inner-city women with FIGO (International Federation of Gynecologists and Obstetricians) stage Ib cervical cancer diagnosed and treated at a single institution between 1986 and 1993. The patient age at diagnosis averaged 49 years, and most of the patients were black (83%). Squamous carcinomas predominated (75%). Radiotherapy was the most frequent treatment modality (49%), followed by surgery (38%) and combined radiation/surgery (13%). The Kaplan-Meier estimated 4-year survival for all patients completing treatment was 81%. Increased survival was significantly associated with therapy. The Kaplan-Meier estimated survival at 26 months (the time of the last death in radiotherapy patients) was 66% for radiotherapy patients and 100% for those treated with surgery. Radiotherapy patients differed from surgery patients in age, tumor size, and pelvic lymph node status, indicating that treatment selection bias could explain the observed difference in survival. Age, race, histology, and cervical lesion size were not significantly associated with survival.

Human papillomavirus and disease status following therapy for cervical cancer.

We enrolled 85 patients with invasive cervical cancer and collected cervicovaginal lavage samples at each clinical visit for diagnosis, staging, treatment, and follow-up. Lavage samples were tested by L1 consensus polymerase chain reaction for human papillomavirus (HPV). Results were compared with HPV demonstrated in tumor tissue and the clinical status at time of sample collection. Sensitivity and specificity of the lavage for detection of tumor HPV, determined on the basis of results of tests on lavage samples collected prior to therapy, were found to be 56% and 76.9%, respectively. The proportion of lavage samples detecting tumor HPV decreased significantly with treatment, from 0.54 at diagnosis to 0.03 at complete response (P < .001). Local treatment failure was associated with increased detection of tumor HPV; however, no samples were positive prior to clinically detected treatment failure. These results suggest that cervicovaginal lavage is not an effective sampling method for epidemiological analysis of HPV in cervical tumors.

A technique for the use of afterloading 137Cs brachytherapy in renal-sparing irradiation of bilateral Wilms tumor.

PURPOSE: To describe a renal sparing brachytherapy technique for treating patients with bilateral Wilms tumor who have limited residual tumor measuring 2 cm or less after initial chemotherapy. METHODS AND MATERIALS: A technique for using brachytherapy in the radiotherapeutic management of bilateral Wilms tumor is described. Three patients with bilateral Wilms tumor were treated at our institutions. All three patients had initial nephrectomy of the contralateral kidney followed by chemotherapy. Local excision of residual tumor in the remaining kidney was done in all three cases. A 137Cs isotopic source was placed in the tumor bed at the time of the second surgery using a simple afterloading applicator. The techniques of applicator placement, localization, and brachytherapy dosimetry are described. The minimum tumor dose varied from 16 to 25 Gy. RESULTS: All three patients are alive and well at 28, 48, and 66 months after the procedure. There were no serious operative or postoperative sequelae. CONCLUSIONS: This simple brachytherapy technique was effective in selected cases of bilateral Wilms tumor where a renal-sparing radiotherapy approach was needed. This technique is most applicable when there is residual intrarenal tumor after partial nephrectomy, when the tumor is unifocal, and when the tumor bed is less than 2 cm diameter.

Cellulitis of the breast as a complication of breast-conserving surgery and irradiation.

Breast-conserving therapy (BCT) has become a standard treatment option for patients with early-stage breast cancer. We have observed cellulitis of the treated breast as a complication occurring before, during, and after breast irradiation. The cases of five women (median follow-up, 28 months; range, 24-65 months) who developed cellulitis before (n = 1), during (n = 2), or after (n = 2) breast irradiation were reviewed. A consecutive series of BCT patients at Emory University was reviewed to determine the incidence of this complication. Four of five women had an axillary dissection, yielding a median of 14 negative lymph nodes (range, 6-22 nodes). Two of four patients developed axillary seromas requiring aspiration. In these four patients, only the breast was irradiated. A fifth patient had no axillary dissection and had breast and supraclavicular/axillary irradiation. The median whole breast dose was 50 Gy (range, 46-50.4 Gy). The clinical features of cellulitis included erythema, edema, tenderness, and warmth in all patients. Cellulitis was a relapsing problem for four of the five patients. The incidence of this complication in our series of BCT patients was approximately 1%. Cellulitis in the ipsilateral breast can be a relapsing complication of BCT and can be seen before, during, or after breast irradiation. Axillary seromas and aspiration seem to indicate a subset of patients at risk of early cellulitis. Late cellulitis may be caused by a variety of factors related to modifications of vascular and skin integrity by surgery and radiotherapy. Prompt diagnosis and appropriate antibiotic therapy is recommended. This problem need not interrupt a course of breast irradiation, and does not necessarily lead to a poor cosmetic result.

Cervical cancer survival in a high risk urban population.

BACKGROUND: Cervical cancer remains an important public health problem, particularly for the urban minority population. To the authors' knowledge, determinants of cervical cancer survival have not been studied in this high risk population. METHODS: This study included all 158 women diagnosed and treated for invasive cervical cancer from January 1, 1986, through December 31, 1992, at the Grady Memorial Hospital and Clinics (Atlanta, GA). Medical records were abstracted to determine age at diagnosis, race, International Federation of Gynecology and Obstetrics (FIGO) clinical stage, treatment, and survival. Pathologic material was reviewed to confirm the diagnosis. RESULTS: Most patients (80%) were African American, and the stage distribution was similar for African American and white patients. Sixty-six (42%) had FIGO Stage I disease; 50%, Stage II or III; and 8%, Stage IV. Four-year actuarial survival differed significantly according to clinical stage (Ia = 94%, Ib = 79%, II = 39%, III = 26%, IV = 0%). Overall survival was lower for patients with glandular carcinomas than for those with squamous cell carcinomas (26% vs. 55%, P = 0.09). This difference was almost entirely due to increased mortality in patients with Stage Ib adenocarcinomas (53% vs. 88% for squamous cell carcinoma, Stage Ib, P = 0.03). CONCLUSIONS: The major prognostic markers for cervical cancer survival in this high risk patient population were clinical stage and histology, factors identical to those identified for other populations.

Human papillomavirus and disease-free survival in FIGO stage Ib cervical cancer.

To determine if human papillomavirus (HPV) in the primary tumor was associated with disease-free survival of stage Ib cervical cancer patients, archival tissues from 47 patients were analyzed for HPV DNA by in situ hybridization (ISH) and polymerase chain reaction. HPV integration was determined by ISH signal pattern. Laboratory data were correlated with clinical parameters and disease-free survival. Kaplan-Meier estimates of 4-year disease-free survival were 56% in women with HPV detected in the primary tumor by ISH and 100% for women in whom HPV was not detected (P = .02). Four-year disease-free survival was 39% for patients with integrated HPV in the primary tumor (P = .005 vs. HPV-negative tumors and .05 vs. HPV episomal or episomal/integrated). HPV detection and integration state was not associated with any other clinical variable. Detection of integrated HPV DNA in the primary tumor was strongly associated with treatment failure.

Squamous cell carcinoma of the cervix metastatic to a drain site.

A squamous cell carcinoma of the cervix metastatic to the skin at the site of a previous retroperitoneal drain is detailed. A review of the literature concerning skin metastases in cervical cancer is also presented. This is the only case the authors can find in the literature of squamous carcinoma of cervix metastasizing to a drain site.

The relationship between brachytherapy dose and outcome in patients with bulky endocervical tumors treated with radiation alone.

PURPOSE: To evaluate the relationship between brachytherapy dose and outcome in patients treated with external radiotherapy (40 Gy to the whole pelvis) and intracavitary radium therapy for bulky endocervical tumors. METHODS AND MATERIALS: Between 1962 and 1985, 98 patients with Stage IB-IIB bulky endocervical carcinomas (> or = 6 cm in diameter) treated with radiotherapy alone received 40 Gy to the whole pelvis followed by 2 or more intracavitary treatments. Twenty-five patients received < 6000 mg-hr of intracavitary treatment and 73 received > or = 6000 mg-hr (an average dose to point A of approximately 49 Gy). Brachytherapy exposures ranged from 4800-7885 mg-hrs. RESULTS: Patients who received < 6000 mg-hr tended to have unfavorable (narrow) vaginal anatomy (p < 0.01) and to be treated in the later years of the study (p < 0.01). The high-dose group included a somewhat greater proportion of patients with positive lymphangiograms or poor responses to initial external beam treatment. Despite having somewhat more favorable tumors, patients who received less than 6000 mg-hr had a higher rate of pelvic disease recurrence at 5 years (33%) than those who received higher doses (16%) (p = 0.03). Actuarial survival rates at 5 years were 44% and 60% for the low- and high-dose groups, respectively (p = 0.14). Among those who received more than 6000 mg-hr, there was no significant relationship between brachytherapy dose and pelvic disease control. Calculated actuarially, the rate of major (> or = grade 3) complications at 5 years was 23% in the low-dose group and 10% in the high-dose group (p = 0.1). CONCLUSIONS: The relatively high incidence of pelvic disease recurrence and complications in patients who receive less than 6000 mg-hr reflects the narrow therapeutic window for complication-free pelvic disease control in patients with bulky central disease and unfavorable normal tissue anatomy. The results also demonstrate a high pelvic control rate and acceptable morbidity in patients with favorable anatomy treated with high-dose radiotherapy alone.

Bulky endocervical carcinoma: a 23-year experience.

Between 1962 and 1985, 371 patients had initial treatment for bulky endocervical carcinomas of the uterine cervix at The University of Texas M.D. Anderson Cancer Center. All patients had concentric expansion of the cervix by tumors that measured at least 6 cm in greatest transverse diameter. Of the 361 patients treated with curative intent, 211 (57%) had FIGO Stage I disease that was believed to be confined to the uterus, 59 (16%) had FIGO Stage IIA disease, and 101 patients (27%) had FIGO Stage IIB disease. Median follow-up time of surviving patients was 130 months. Actuarial survival rates of 361 patients treated with curative intent were 54% and 48% at 5 and 10 years, respectively. The actuarial pelvic disease control rate was 76% at 10 years. Patients whose tumors were less than 8 cm in maximum diameter (279 patients) had a better survival rate than those with tumors greater than or equal to 8 cm in diameter (92 patients) (p less than 0.01). Of the 282 patients who underwent lymphangiography, survival rate was significantly better for those with negative studies than it was for the 113 patients (40%) with positive or suspicious studies (p less than 0.01). There was no correlation between FIGO stage and survival rate (p = 0.64) or pelvic control rate (p = 0.59). Of patients treated with curative intent, treatment was by radiation alone (RT) in 244 (68%) or by radiation followed by hysterectomy (RT+S) in 117 (32%). Although there has been an overall shift in policy away from the use of adjuvant hysterectomy during the past decade, many patient selection factors also influenced the choice of treatment during the study years, resulting in a significantly higher proportion of patients with adverse prognostic features in the RT group. Patients chosen for treatment with RT alone had a greater likelihood of having tumors greater than or equal to 8 cm (p = 0.03), FIGO stage IIB (p less than 0.01), positive lymphangiogram (p = 0.02), and persistent palpable parametrial disease after external radiotherapy (p less than 0.01). Patients treated with RT alone also had a lower overall survival rate at 10 years than patients treated with RT+S (45% vs 64%, p less than 0.01). Although multivariate analysis suggested that treatment had an independent influence upon survival rate, it was difficult to draw firm conclusions about the value of adjuvant surgery because of the numerous biases in patient selection, some of which may have been difficult to quantify.(ABSTRACT TRUNCATED AT 400 WORDS)

Multimodal treatment for inflammatory breast cancer.

This is a retrospective study of 61 patients with clinically diagnosed breast cancer (IBC) treated with multimodality therapy between September 1977 and September 1985. All patients were scheduled to receive three courses of doxorubicin-based chemotherapy followed by mastectomy, further chemotherapy, and postoperative irradiation. Ten patients (16%) obtained a complete response, defined as either resolution of the clinical signs of inflammatory breast cancer (IBC) (4 patients) or no evidence of tumor in the mastectomy specimen (6 patients). Twenty-seven patients (45%) obtained a partial response, defined as a greater than 50% reduction in the clinical signs of inflammatory breast cancer. No response occurred in 24 patients (39%). Immediate mastectomy was done in 56 patients. Five patients whose disease was not resectable received preoperative irradiation. Nine patients at high risk for locoregional failure received postoperative irradiation immediately after mastectomy and before additional chemotherapy. Postoperative irradiation was given to the chest wall and peripheral lymphatics using standard or accelerated fractionation to a maximum dose of 60 Gy. Forty-six patients completed planned treatment including chemotherapy, surgery, and radiotherapy without failure. The minimum follow-up was 36 months. The 5-year actuarial disease-free survival was 70% for the complete response group, and 35% for the partial response group. All patients with no response failed by 34 months. The actuarial 5-year disease-free survival rate for the entire group was 27%. The 5-year actuarial locoregional control was 89% in the complete response group, 68% in the partial response group, 33% in the no response group, and 58% for all patients. Most failures were on the chest wall within the irradiated volume. Chest wall failures were more frequent in those who did not achieve brisk erythema or moist desquamation after postoperative irradiation. We conclude that multimodal treatment of patients with inflammatory breast cancer results in a low incidence of failure if complete response is obtained following initial chemotherapy. The locoregional control rate and actuarial 5-year disease-free survival for the entire group were not improved when mastectomy was done. Surgery should be done in those patients who respond adequately to chemotherapy, so that late sequelae of high-dose breast irradiation can be eliminated. Higher doses of postoperative irradiation may be required to improve local control in those patients with the poorest response to initial chemotherapy.
