Cervical lymph node metastasis from an unknown primary: is a tonsillectomy necessary?

Purpose: The detection of an infraclinical primary by tonsillectomy in case of cervical lymph node of an epidermoid carcinoma with unknown primary after a radical neck dissection, allows avoiding irradiation of the normal larynx. The aim of this study is to quantify the rate of tonsil primary to justify this procedure.

Methods And Materials: From 1969 to 1992, 87 patients had a tonsillectomy as part of the workup for cervical nodal metastasis of an epidermoid carcinoma with unknown primary.

[Optimization of dose distribution of radiation in cancers of the cavum: association of an expert-system and a mathematical algorithm].

Optimization of radiation therapy in nasopharyngeal carcinoma is particularly complex due to both the proximity of at risk organs and the high dose that has to be delivered. To obtain an optimal dose distribution, a knowledge-based optimization technique has been designed that associates an expert-system, named CAVCAV, with numeric optimization (gradient projection method). Based on clinical and physical criteria, CAVCAV determines the geometric characteristics of the radiation fields (beam direction, location and shape of the shielding blocks) for the three stages of radiation therapy of nasopharyngeal carcinomas.

Advanced carcinoma of the larynx: results of surgery and radiotherapy without induction chemotherapy (1980-1985): a multivariate analysis.

Purpose: Induction chemotherapy has been proposed in the case of advanced laryngeal cancer in order to preserve laryngeal function in those patients who are complete responders. To clarify the treatment policies, a retrospective multicentric analysis of 116 patients with advanced carcinoma of the larynx treated by radical surgery and postoperative radiotherapy was carried out in order to evaluate prognostic factors for local control and survival.

Methods And Materials: Between 1980 and 1985, 116 patients with Stage III squamous cell carcinoma of the larynx underwent radical surgery and postoperative radiotherapy with a curative intent.

From 1977 to 1991, we treated 361 carcinomas of the velotonsillar region, either by brachytherapy alone (18 cases), or by an association of external radiotherapy and brachytherapy (343 patients). The latter was performed using a special technique with iridium wires in plastic tubes with afterloading. The primary was the tonsil in 128 patients, the soft palate in 134 patients.

An original technique of brachytherapy in the treatment of epidermoid carcinomas of the buccal mucosa.

Purpose: To report our experience using brachytherapy in buccal mucosa carcinoma with particular attention on the technique of implantation used and on the elective treatment to the lymph nodes.

Methods And Materials: From 1973 to 1991, 42 patients (36 T1 T2 T3, 35 NO) were treated for epidermoid carcinoma of the buccal mucosa as the first site of head and neck cancer. To study the local control, the group of 36 T1-3 patients was divided into two groups according to the brachytherapy technique used: the parallel wires technique and the loop technique (M.

Detection of errors in individual patients in radiotherapy by systematic in vivo dosimetry.

We report 5 years of systematic measurements of the dose delivered to each patient undergoing radiotherapy treatment with photon beams in order to detect any systematic error that may have escaped the different checks performed at each step of planning and calculation prior to the first treatment session, or may have arisen during the set-up or the treatment delivery. For each patient the target-absorbed dose is derived from the entrance and exit doses measured by silicon diodes, on the beam axis at the patient's skin. Depending on the discrepancies observed between the measured and expected doses we have set decision levels for the corrective actions to be taken.

Influence of tumoral, radiobiological, and general factors on local control and survival of a series of 361 tumors of the velotonsillar area treated by exclusive irradiation (external beam irradiation+brachytherapy or brachytherapy alone).

Purpose: To evaluate statistically the factors influencing the therapeutic results.

Methods And Materials: A statistical study was carried out concerning 361 patients treated from 1977 to 1991 for velotonsillar carcinoma. They received either brachytherapy alone (18) or a combination of external beam irradiation and brachytherapy (343 patients) using an afterloading iridium technique in plastic tubes.

Iridium-192 brachytherapy in the management of 147 T2N0 oral tongue carcinomas treated with irradiation alone: comparison of two treatment techniques.

Our purpose is to analyse local control, complications relative to the proportion of total dose delivered by external beam irradiation versus interstitial implant in 147 patients with previously untreated T2N0 squamous cell carcinoma of the oral tongue, managed between 1973 and 1986 (UICC staging system). These T2N0 patients are part of a larger group of 430 patients with oral tongue carcinoma (T1, T2, T3) treated with irradiation alone. Of these 147 T2N0 patients, 70 were treated with interstitial implant alone and 77 with both external beam irradiation and implant.

The distribution of patients according to the localisation was as follows: 106 tonsillar region, 98 soft palate, 45 anterior pillar, 8 posterior pillar and 20 pharyngoglossal sulcus. According to the UICC TNM classification of 1979, the patients were staged as follows: 65 T1, 103 T2, 101 T3, 8 TX.
