Radiosurgery of cerebral arteriovenous malformations in children: a series of 57 cases.

Purpose: To evaluate the efficacy and outcome of Linac radiosurgery (RS) as treatment of cerebral arteriovenous malformations (cAVM) in a series of 57 children.

Methods And Materials: Between 1984 and 2000, we used Linac radiosurgery to treat 792 patients with cAVM. This series included 57 children (7.

Results of definitive irradiation in a series of 305 epidermoid carcinomas of the anal canal.

Purpose: To evaluate our data concerning the prognostic factors for locoregional control, survival, late complications, and sphincter conservation in a series of epidermoid cancers of the anal canal without clinical evidence of metastasis.

Methods And Materials: Between June 1972 and January 1997, 305 patients were treated with curative-intent radiotherapy (RT). The T stage according to the 1987 International Union Against Cancer classification was T1 in 26, T2 in 141, T3 in 104, and T4 in 34.

Repeat linear accelerator radiosurgery for cerebral arteriovenous malformations.

Purpose: To evaluate repeat radiosurgery (RS2) for cerebral arteriovenous malformations (AVMs) after failure of initial radiosurgery (RS1).

Methods And Materials: Between 1986 and 2000, 41 patients underwent RS2. Nine patients were not assessable: seven had insufficient follow-up (RS2 in 1999 and 2000) and two had no recent control angiography data.

Operable Stages IB and II cervical carcinomas: a retrospective study comparing preoperative uterovaginal brachytherapy and postoperative radiotherapy.

Purpose: To evaluate our data concerning prognostic factors and treatment toxicity in a series of operable cervical carcinomas.

Methods And Materials: Between May 1972 and January 1994, 414 patients with cervical carcinoma, staged according to the 1995 FIGO staging system (286 Stage IB1, 38 Stage IB2, 56 Stage IIA, and 34 Stage IIB with 1/3 proximal parametrial involvement), underwent radical hysterectomy with (n = 380) or without (n = 34) bilateral pelvic lymph node dissection (N+: n = 68). Group I included 168 patients who received postoperative radiation therapy (RT): 64 patients had low-dose-rate vaginal brachytherapy with a median total dose (MTD) of 50 Gy; 93 patients had external beam pelvic RT (EBPRT) with an MTD of 45 Gy over 5 weeks, followed by low-dose-rate vaginal brachytherapy (MTD: 20 Gy); and 11 patients had EBPRT alone (MTD: 50 Gy over 6 weeks).
