Chemoradiation for primary invasive squamous carcinoma of the vagina.

OBJECTIVE: To report outcomes for patients with primary, invasive, squamous carcinoma of the vagina treated with chemoradiation. METHODS: Between 1986 and 1996, 14 patients were treated with primary therapy consisting of synchronous radiation and chemotherapy. Patients were judged not to be surgical candidates based on tumor size, location, and concerns related to urinary, bowel, or sexual function. Three patients were FIGO stage I, ten patients stage II, and one patient stage III. Radiation consisted of teletherapy alone (six patients) or in combination with intravaginal brachytherapy (eight patients). Total radiation dose ranged from 5700 to 7080 cGy (median 6300 cGy). Chemotherapy consisted of 5-fluorouracil alone (seven patients), or with cisplatin (six patients) or mitomycin-C (one patient). RESULTS: One patient failed locally at 7 months and died of disease at 11 months. Four patients died of intercurrent illness (46, 92, 104, 109 months) and nine are alive and cancer-free 74-168 months after treatment (median 100 months). There were no vesicovaginal or enterovaginal fistulae. CONCLUSIONS: Radiation with synchronous chemotherapy is an effective treatment for squamous carcinoma of the vagina. Cancer control outcomes compare favorably with previously published results employing higher dose radiation as monotherapy.

Endometriosis-related malignancies.

The purpose of this study is to describe the clinical findings, treatment, and outcome of patients with endometriosis-related cancers. Patients meeting Sampson and Scott's criteria for cancer associated with endometriosis in the Sacramento region were identified by chart review and pathology reports. Twenty-seven patients were identified with endometriosis-related malignancies (mean age 51.4 years). The site of origin was ovary in 17 (63.0%) and extra-ovarian in 10 (37%) including vagina, fallopian tube or mesosalpinx, pelvic sidewall, colon, and parametrium. The pattern of spread was local in five (18.5%), regional in 20 (74.1%) and distant in two (7.4%). Six patients had taken unopposed estrogen replacement (mean duration 23.4 years) and all six had extragonadal disease. Surgical procedures included hysterectomy, salpingo-oophorectomy, radical local excision, partial colectomy, and surgical staging. Eighteen patients received postoperative chemotherapy since the majority of patients had ovarian involvement. Fifteen patients received regional radiation therapy. Nineteen patients are without evidence of recurrence (70.4%, mean follow-up of 31 months). Endometriosis-related malignancies have a favorable prognosis. Extragonadal disease was commonly associated with unopposed estrogen replacement therapy. The predominance of local and regional disease strongly influence the application of treatment modalities.

Obstetrical deliveries associated with maternal malignancy in California, 1992 through 1997.

OBJECTIVE: This study aims to characterize the rate of occurrence and nature of outcomes associated with obstetrical deliveries in women with malignant neoplasms among 3,168,911 women who delivered in California in 1992 through 1997. DESIGN: The study is a population-based retrospective review of infant birth and death certificates and maternal and neonatal discharge records. Cases of malignant neoplasms associated with obstetrical delivery were attributed to 1 of 3 categories, depending on the earliest documented hospital discharge diagnosis, as follows: "prenatal" if the diagnosis was first documented by hospitalization within 9 months preceding delivery, "at delivery" if the diagnosis was established from the delivery hospitalization, or "postpartum" if the diagnosis was first documented by hospitalization within 12 months after delivery. METHODS: Computer-linked infant birth and death certificates and maternal and neonatal discharge records were used to identify cases and outcomes. Cases of malignant neoplasms were identified by using International Classification of Diseases, Ninth Revision codes (140-208). Noninvasive neoplasms and carcinoma in situ neoplasms were excluded. In analysis of outcomes, the Mantel-Haenszel estimate for adjusted odds ratios was used. RESULTS: Among 3,168,911 obstetrical deliveries over the 6-year span, a total of 2247 cases of primary malignancy were identified. The observed rate of occurrence for primary malignant neoplasms was 0.71 per 1000 live singleton births. Most cases (53.3%) were first documented in the postpartum period as follows: prenatal, 587 cases (0.18 per 1000); at delivery, 462 cases (0.15 per 1000); and postpartum, 1198 cases (0.38 per 1000). The most frequently documented primary malignant neoplasms associated with obstetrical delivery were breast cancer (423 cases, 0.13 per 1000), thyroid cancer (389 cases, 0.12 per 1000), cervical cancer (266 cases, 0.08 per 1000), Hodgkin's disease (172 cases, 0.05 per 1000), and ovarian cancer (123 cases, 0.04 per 1000). Odds ratios for a variety of demographic factors identified maternal age as the most significant risk factor for development of malignant neoplasms (age greater than 40 vs 20-25, odds ratio 5.7, CI 4.6-6.9). Age-adjusted odds ratios for maternal cancer of any type suggested significantly elevated risks for cesarean delivery (odds ratio 1.4, CI 1.3-1.6), blood transfusion (odds ratio 6.2, CI 4.5-8.5), hysterectomy (odds ratio 27.4, CI 20.8-36.1), and maternal postpartum hospital stay greater than 5 days (odds ratio 30.6, CI 27.9-33.6), but not for postpartum maternal death (odds ratio 0.8, CI 0.6-1.0). Odds ratios also suggested significantly elevated risks for premature newborn (odds ratio 2.0, CI 1.8-2.2), very low birth weight (odds ratio 2.9, CI 2.2-3.8), and newborn hospital stay longer than 5 days (odds ratio 2.6, CI 2.4-3.0), but not for neonatal death (odds ratio 1.6, CI 0.8-3.1) or infant death (odds ratio 1.2, CI 0.5-3.3). However, several types of malignant neoplasms did confer significant elevations in risk for neonatal death. Hospital charges for both maternal and neonatal care were significantly elevated in the maternal malignant neoplasm group. CONCLUSION: A lower than expected occurrence rate of obstetrical delivery associated with maternal malignancy was seen when compared with previously published hospital-based reports. Malignant neoplasms associated with obstetrical delivery were most frequently first documented in the postpartum period. Maternal and neonatal morbidity were significantly increased, yet the risk of in-hospital maternal death was not significantly elevated. A significant increase in risk of neonatal death for infants of mothers with cervical cancer was found.
