Abstract
OBJECTIVE Optimal management of the contralateral groin in patients with early-stage vulvar squamous cell carcinoma (VSCC) and a metastatic unilateral inguinal sentinel lymph node (SN) is unclear. We analyzed patients who participated in GROINSS-V I or II to determine whether treatment of the contralateral groin can safely be omitted in patients with a unilateral metastatic SN. METHODS We selected the patients with a unilateral metastatic SN from the GROINSS-V I and II databases. We determined the incidence of contralateral additional non-SN metastases in patients with unilateral SN-metastasis who underwent bilateral inguinofemoral lymphadenectomy (IFL). In those who underwent only ipsilateral groin treatment or no further treatment, we determined the incidence of contralateral groin recurrences during follow-up. RESULTS Of 1912 patients with early-stage VSCC, 366 had a unilateral metastatic SN. Subsequently, 244 had an IFL or no treatment of the contralateral groin. In seven patients (7/244; 2.9% [95% CI: 1.4%-5.8%]) disease was diagnosed in the contralateral groin: five had contralateral non-SN metastasis at IFL and two developed an isolated contralateral groin recurrence after no further treatment. Five of them had a primary tumor ≥30 mm. Bilateral radiotherapy was administered in 122 patients, of whom one (1/122; 0.8% [95% CI: 0.1%-4.5%]) had a contralateral groin recurrence. CONCLUSION The risk of contralateral lymph node metastases in patients with early-stage VSCC and a unilateral metastatic SN is low. It appears safe to limit groin treatment to unilateral IFL or inguinofemoral radiotherapy in these cases.

Abstract
Our study focused on the influence of herpes simplex virus thymidine kinase (HSV-tk) expression and ganciclovir (GCV) treatment on the sensitivity of C6 glioma cells to frequently used chemotherapeutic drugs, i.e. adriamycin (ADR), cisplatin (CDDP), 5-fluorouracil (5-FU), and methotrexate (MTX). Transfection with HSV-tk revealed an increased sensitivity to GCV and CDDP and a decreased sensitivity to ADR and MTX. No significant differences were found in sensitivity to 5-FU. Combined treatment in a HSV-tk negative cell line revealed an additive effect when GCV was combined with ADR, whereas an antagonistic effect was found when GCV was combined with CDDP, 5-FU, or MTX. Comparable results were obtained in an HSV-tk positive cell line, apart from CDDP, which showed an additive effect. In conclusion, both HSV-tk transfection and subsequent GCV treatment can influence the sensitivity of tumor cells to various chemotherapeutic drugs in an antagonistic manner. Therefore, combining HSV-tk/GCV gene therapy with chemotherapy might not always be beneficial.

Abstract
Prospectively, the relationship between androgen levels in the utero-ovarian circulation, aromatase activity in endometrial and body fat tissue, and the presence or absence of endometrioid endometrial cancer was studied in postmenopausal women. In 43 women with endometrioid endometrial cancer and 8 women with a benign gynecological condition, a hysterectomy with bilateral salpingo-oophorectomy was performed. Using tritium water-release assays, aromatase activities in endometrial and body fat tissue were determined and related to the steroid levels from the peripheral and the utero-ovarian venous circulation (estradiol, androstenedione, testosterone) and to the presence or absence of endometrial cancer. Significant aromatase activity was found in both benign and malignant endometrial tissue samples. Aromatase activity in samples of endometrial tissue and in samples of body fat did not correlate with steroid levels in peripheral or utero-ovarian venous blood. Aromatase activity in samples of benign or malignant endometrium did not differ. Remarkably, in four women with mainly poorly differentiated endometrial cancer, very high aromatase activity was found in endometrial tissue. It is likely that multiple pathogenetic pathways exist that eventually lead to the formation of endometrioid endometrial cancer. The local availability of androgens and the finding that aromatase activity is present in both endometrial cancer and benign endometrial tissue support the hypothesis that aromatase activity in the endometrium may play a role in malignant transformation by converting androgens into mitogenic estrogens in the endometrial tissue.

Abstract
BACKGROUND Concurrent radiochemotherapy is currently considered the new standard treatment in locally advanced cervical cancer. PATIENTS AND METHODS Eight women with cervical cancer stage IB2-IVA were treated with standard radiation therapy in combination with standard carboplatin (AUC=2, once weekly, x 6) and escalating doses of paclitaxel (60 mg/m2, once weekly, x 4, then x 5 and x 6). RESULTS At the lowest dose level, four weekly paclitaxel cycles in six patients, three developed grade III diarrhoea and one severe radiation enteritis several weeks after radiotherapy. Two patients did not achieve complete remission and underwent additive salvage hysterectomy. All patients remained free of local recurrence, but one patient had distant metastases after 13 months. The median disease-free survival was 25 months with a median follow-up of 26 months. CONCLUSION Standard pelvic radiotherapy in combination with weekly carboplatin and paclitaxel is poorly tolerated due to dose-limiting diarrhoea.
