Flap algorithm in vulvar reconstruction after radical, extensive vulvectomy.

The objective of this study was to assess the reconstructive options after radical, extensive vulvectomy; relate them to tumor characteristics; and select a choice of flaps able to correct every remaining defect. This study is a retrospective review of a 4-year experience with 31 flaps in 20 consecutive vulvar reconstructions. Three of the 31 flaps presented nonsignificant delayed healing at their tips and 3 other flaps developed a major breakdown related to an infection or an error in flap planning. According to the authors, the size of the defect is the main issue that must be taken into consideration during the establishment of reconstructive needs. Closure of vulvar defects is preferably performed using fasciocutaneous flaps, which are very reliable flaps and can be raised with different techniques to meet different needs. A flap is then chosen with the fewest potential complications. An algorithm has been thus established: Small to medium-size defects are closed with island V-Y flaps, island gluteal fold flaps, or pedicled pudendal thigh flaps. Among them, the island V-Y flap is the workhorse flap for vulvar reconstruction because of its versatility, reliability, and technical simplicity compared with its very low complication rate. If the vulvar defect is large and/or reaches the vulva-crural fold, V-Y flaps are also preferred to close these large and posteriorly extended excisions. If the vulvar defect is very large, extending both anteriorly and posteriorly, the use of a distally based, vertically oriented rectus abdominis muscle flap is recommended. Using this algorithm, immediate vulvar reconstruction with pedicled local or regional flaps can be performed easily and reliably.

Concurrent 5-fluorouracil, mitomycin C and radiation with or without brachytherapy in recurrent cervical cancer: a scoring system to predict clinical response and outcome.

AIMS AND PURPOSE: This is a prospective, phase II study aimed to evaluate the effect of concurrent 5-fluorouracil, mitomycin C, and radiation with or without brachytherapy on the clinical outcome of a series of recurrent cervical cancer patients and to determine the prognostic impact of a subset of factors. METHODS: Thirty-three patients with locally recurrent, non-metastatic cervical cancer received external beam radiation (4-week split course: 23.4 + 23.4 Gy) plus two courses of concomitant chemotherapy (5-fluorouracil, 96-h continuous infusion, days 1-4, 1 g/m2/day; mitomycin C, 10 mg/m2, bolus i.v., day 1). Twelve patients with vaginal recurrence (36.4%) underwent endocavitary low-dose rate brachytherapy boost (20-25 Gy); 11 patients with lateral pelvic recurrence (33.3%) received external beam radiation boost (14-20 Gy). RESULTS: Fourteen complete responses (42.4%), 7 partial responses (21.2%), 5 disease stabilizations (15.1%) and 7 progressions (21.2%) were obtained. After a median follow-up of 34 months (range, 6-127), overall actuarial 3-year survival, progression-free survival and local progression-free survival were 59.7%, 48.1% and 51.7%, respectively. Patients with vaginal recurrence of less than 4 cm and negative lymph nodes proved to respond best to the treatment. Two patients (6.1%) experienced hematologic grade 3 toxicity. One patient had grade 3 intestinal toxicity (3.0%). No patient had major skin or urological acute toxicity. Severe late toxicity was infrequent. Three patients had prolonged leukopenia (9.0%). Four patients showed severe vaginal stenosis (12.1%). A clinical score of 0 to 1 was assigned to each patient on the basis of the absence (score = 0) or presence (score = 1) of any of the following prognostic factors: time between surgery and recurrence shorter than 12 months, pelvic wall site of recurrence, positive lymph nodes, hemoglobin < 11 g/dL. Using this system, it was clear that patients with a low total score had a significantly better outcome (clinical remission, 51% of patients with a score < or = 2 vs 12% of patients with a score > 2, P = 0.06), local control of the disease (65% vs 20% after 3 years, P = 0.001,) and overall survival (75% vs 30% after 3 years, P = 0.032). CONCLUSIONS: Our data suggest that this combined modality therapy was relatively well tolerated and resulted in reasonable local control and survival. The scoring system proved to be helpful to identify patients with the greatest chance of benefiting from the treatment. Further studies are probably needed to salvage the other patients, whose prognosis remains severe.

Concurrent 5-fluorouracil, mitomycin C and radiation, with or without brachytherapy, in recurrent endometrial cancer: a scoring system to predict clinical response and outcome.

AIMS AND BACKGROUND: This prospective, phase II study aimed to test the efficacy of concurrent 5-fluorouracil, mitomycin C and radiation, with or without brachytherapy, on the clinical outcome of a series of recurrent endometrial cancer patients and to determine the prognostic impact of a subset of factors. METHODS: Thirty patients with locally recurrent, nonmetastatic endometrial cancer received external beam radiation (4-week split course: 23.4 + 23.4 Gy) plus two courses of concomitant chemotherapy (5-fluorouracil, 96-h continous infusion, days 1-4; 1 g/m2/day; mitomycin C, 10 mg/m2, bolus iv, day 1). Nineteen patients (63.3%) underwent endocavitary, low-dose brachytherapy boost (20-25 Gy); eight patients (26.7%) received external beam radiation boost (14-20 Gy). RESULTS: Eleven complete responses (36.7%), 11 partial responses (36.7%), 6 disease stabilizations (20.0%) and 2 progressions (6.6%) were observed. After a median follow-up of 27 months (range, 1-108), overall actuarial 3-year survival, progression-free survival and local progression-free survival were 46.8%, 35.2% and 41.2%, respectively. Two patients (6.7%) experienced hematological grade 3 toxicity. Two patients (6.7%) had grade 3 intestinal toxicity. Severe late toxicity was infrequent, only 3 patients showing severe vaginal stenosis (10.0%). A clinical score of 0 to 1 was assigned to each patient on the basis of the absence (score = 0) or presence (score = 1) of any of the following prognostic factors: time between surgery and recurrence shorter than 12 months, pelvic wall site of recurrence, positive lymph nodes, hemoglobin < 11 g/dL. With this device, it was clear that patients with a low score had a significantly better outcome (clinical remission: 77.2% of patients with a score < 2 vs 25.0% of patients with a score > or = 2, P = 0.009), better local control of the disease (50.2% vs. 0 at 3 years, P = 0.014,) and better overall survival (65.8% vs 0 at 3 years, P = 0.003). CONCLUSIONS: Our data suggest that this combined modality therapy was relatively well tolerated and resulted in reasonable local control and survival. The scoring system proved to be helpful in identifying patients with the best chance of benefiting from the treatment.
