[Adenoid cystic carcinoma of the head and neck: a retrospective series of 169 cases].

Purpose: Adenoid cystic carcinoma represents 1% of head and neck cancers. Adenoid cystic carcinomas are slow growing tumours with high potential for local recurrence. Treatment usually associates radiotherapy and surgery, but the role of radiotherapy remains unclear.

Anal canal cancer: management of inguinal nodes and benefit of prophylactic inguinal irradiation (CORS-03 Study).

Purpose: To evaluate the benefit of prophylactic inguinal irradiation (PII) in anal canal squamous cell carcinoma (ASCC).

Methods And Materials: This retrospective study analyzed the outcome of 208 patients presenting with ASCC treated between 2000 and 2004 in four cancer centers of the south of France.

Results: The population study included 35 T1, 86 T2, 59 T3, 20 T4, and 8 T stage unknown patients.

[Stage 1 testicular seminoma].

Testicular cancer is rare, representing only 1 % of malignant tumors, but the most common cancer in young men, 15 to 35 years. Adjuvant radiotherapy after orchidectomy in testicular seminoma stage I, reduces risk of relapse. It aims to eradicate micro-metastatic disease in lymph drainage territories.

[Postoperative radiotherapy of uterine sarcoma: a multicentric retrospective study].

Purpose: Surgery is the treatment of choice for localized uterine sarcomas. We conducted a retrospective study to define prognostic factors.

Patients And Methods: We studied 111 cases of patients treated by adjuvant radiotherapy for uterine sarcoma in seven French centers.

[Normal tissue tolerance to external beam radiation therapy: ovaries].

Clinical situations requiring protections of ovaries are mainly paediatric irradiations and pre-menopausal pelvic irradiations. The main complication of ovarian irradiation is the induced castration. Ovaries are extremely radiosensitive organs with strong interpersonal variations.

[Normal tissue tolerance to external beam radiation therapy: testicles].

Although there is very little evidence for direct irradiation of the testes, they may receive significant doses, especially in the treatment of pelvic tumors in adults and in pediatrics. The exocrine function of the testis seems to be more sensitive to radiotherapy. There is a risk of sterility, even after low doses of radiation.
